The new Rotary kiln sealing plate sealing device Langfang million satisfied seal Ltd.

Flexible two-way rolling Rotary kiln sealing Introduction of new air sealing, leak-proof material to scroll both flexible seal device, a number of on-site by the State Bureau of Building Material Machinery Building Materials Quality Supervision and Inspection Center of follow-up supervision and inspection, its technical performance Advanced stability, quality, reliability, operation to be sure, the State Building Materials Bureau and the State Environmental Protection Administration to promote actively promote energy efficient environmentally friendly high-tech new products. The technology and products in order to succeed in cement production enterprises and metallurgical production enterprises, users and achieved good social and economic benefits. Flexible two-way rolling kiln seals, either kiln seal, kiln seal, in the firing system plays a connection between the fixed parts and rotating parts of seal. Firing system is thermal environment to kiln Case not only high temperature, high dust, vacuum process environment, the presence of the rotary kiln barrel ends at the same time, swing, axial movement integrated complex motion, and in use in the presence of an ellipse and bending deformation. Operation process between the rotary member and the presence of the ever-changing fixture radial, axial and circumferential three-dimensional space. When the sealing means is not good, there will be cold air leaking in, thereby increasing the amount of exhaust gas system, by reducing the amount of smoke useful under reasonable conditions, and increase the system thermal consumption, coal consumption. Leakage, ash leakage and unstable process operation led to a decline in yield reduction and quality, to bring unnecessary losses and increased costs. To resolve ash leakage must address leakage, the gap must be addressed and changes in differential pressure. I developed such a sealing means is a flexible structure that can adapt to the kiln kiln at a high temperature state of the deformation, tube deflection and eccentric, because the sealing materials used for the import of high-temperature materials and special heat treatment production process, Therefore, in the case where the kiln temperature of 1000 ℃ ~ 1200 ℃ still maintain good mechanical properties, thus ensuring the sealing effect. Completely solve the problem of the kiln ash leakage and leakage caused by positive pressure, increase kiln tertiary air temperature to ensure the normal thermal environment. Kiln seal transformation will consider the design of kiln feed raw material situation and return back to the material issues scoops, because each design unit is not in-depth study scoop back in the return feed process complex rotating cast material state, the back scoop No work will be thrown into the material in the feed material into the kiln with the tongue, causing material from the kiln and feeding tongue gap leakage, which reduces the life of the feeding tongue and pollutes the environment and the waste of raw materials. To solve the leakage of material must be designed into the material tongue, back scoop and kiln necking, handle the relationship between the three. Our response to these circumstances when a user seal transformation, the first representing the user's existing nuclear necking smoke chamber, ash feeding device, feeding the tongue, mouth guard and iron kiln design is reasonable, then according to the actual situation in line with the user to transform or re-design under the premise of saving money, thus ensuring the normal production conditions no leakage, no leakage of material, the flexible sealing portion, in use, the life assured. Hopper in the rotary kiln is set to ensure that the production is not normal circumstances pouring spit feed material have to go channel hopper outlet pipe connections or focus on lower tower and the tower according to the device under field conditions, so that the material does not leak to the outside of the apparatus and environmental pollution and burns operatives. Avoid security risks, reduce labor intensity, and savings through multi-channel processing into raw material. The new flexible two-way rolling seals: sealing portion with three layers of special high temperature, wear-resistant combination of semi-flexible material, including wear parts, high temperature nickel-silicon-carbon composite panels, protective plate. A combination of semi-flexible hermetic seal structure as a whole may vary depending on the movement and deformation of the kiln, it is a good fit oval ends of the kiln, deformation and rotation, swing and complex motion ran formation. It is fixed to the end of the kiln hood or kiln smoke chamber and the other end without any gap adjust the tension on the rotating cylinder wear specifically set put, gap-free seal, to ensure no leakage and no leakage of material. Leakage, the results will lead to leakage of material kiln flue gas temperature is reduced, lower production, heat consumption, coal consumption increased, a file roller accelerated wear, reduced life, high wind increased electrical energy consumption, environmental pollution and unstable operation processes. The new flexible sealing means can solve the leakage, the problems caused by the leakage of materials, energy saving, guarantee production. Annual cost savings for the user to one million yuan. And long service life, low cost, no maintenance, reliable operation, good sealing effect, easy installation, short construction period of patent products "flexible two-way rolling" sealed for your business energy saving Lixin Gong. Scroll both flexible seal feature is that it uses a special high-temperature, abrasion-resistant non-metallic material is made of semi-flexible (two carbon silicon nickel composite board), you can use the kiln shell perennial arising reliable seal radial and axial clearance. Scroll both flexible seal has the following four characteristics: A, good sealing effect, allows rotary member and seal holder is formed even with the parent, to solve two major problems of air leakage ash leakage. B, low coefficient of friction, under normal operating conditions 3--5 years without replacement; C, the kiln is not damaged, the flexible seal is unique bi-rolling is that the rotary member and seal holder does not directly produce strong friction, so rolling friction surface resistance. Friction surfaces and high temperature, wear resistance, high lubricity carbide mixed material, the turning passive than the direct friction wear surface reduces wear by 50%, average 70% less expensive, easy to scroll both flexible seal structure, no maintenance. In the original scale-piece or two-soft formula based on no major changes can be made to install the device; D, high energy efficiency, long life and good sealing effect + + kiln body is not damaged = high energy efficiency. Scroll both flexible seal patented product, patent No. 201020177210.5. Practice has proved that scroll both flexible seal and the cylinder type, chip scale, compared to the spring pressure plate, sealing different results, before using a flexible two-way scroll seal kiln smoke chamber than the transformation of the negative pressure significantly increased (approximately 200pa so), smoke chamber temperature increase 100 ℃ Contact: Zhang Chun Qi Phone / Fax: 0316-5836039 Mobile: 13910664624 E-mail: hnjcz99@sina.com http://lfyina.b2b.hc360.com
