Stoker coal feeder manufacturers Shandong coal machine

To coal in power plant applications stoker There are many different types, are used in various industries. Take aspects of the plant, they are blending equipment is mainly used in coal handling system as a pick-feed equipment. It can transport up to a program stored in coal and coal silo come to accept and send them to the device under a program to go, namely the use of transportation equipment to transport them to the boiler or other receiving device to go. Currently used in power plants to coal more types of more trouble, such as vibratory excitation type and motor, impeller, belt and scraper, etc., to assist their equipment mainly by the coal plow coal, blending trolley and mobile belt and so on. In addition, electromagnetic and motor vibration to the coal machine is mainly used in the silo discharge, for example, mixed coal bin and a coal storage bunker system, impeller are mainly used in the elongated slotted coal ditch. Belt type is used in the coal hopper bin dumper by nesting. Blending cars and mobile belt conveyor to work in the coal storage-intensive, and in the middle of the storage pulverizing system, they are not very easy to use. At the same time the distribution of the pulverized coal and coal warehouse interwoven place, is not very convenient to use, generally used plow coal.

Second, sealed to constitute coal machine: BRT stoker sealed by a closed pressure hull, conveying systems, weighing systems, cleaning systems, deviation alarm system, control system and out equipment, etc., can be realized stand-alone or with the plant DCS control system network control. Third, the sealed coal main technical indicators: 1, measurement accuracy: ≦ 1% 2, tape width: 400 ~ 2200mm 3, transport capacity: 1 ~ 250t / h 4, belt load: 20 ~ 500kg / m 5, applicable Temperature: ≦ 120 ℃ 6, power supply: 380 ± 10%, 50Hz 7, Instrument Power: 220V ± 10%, 50Hz 8, Sensor: High bellows pressure sensor 9, belt high temperature: 120 ~ 180 ℃ (optional) Fourth, sealed stoker main functions: 1, scale body shell seal pressure to prevent air leakage leakage coal dust, pressure 0.35Mpa. 2, active roller surface of special processing, effectively prevent deviation. 3, the driven roller tension can be adjusted on the outer body. 4, with automatic cleaning structure. 5, all the maintenance window slot structure, good sealing effect. 6, automatically cleared, by a simple operation, the instrument automatically clears the seal scales. 7, variable-speed control, automatic control instrumentation PID regulation. 8, with the plant DCS network control. 9, with 4 ~ 20mA current output. 10, with R485 serial communication. 11, a variety of school scale way, free chain code calibration, hang code calibration, calibration, and other kind of calibration methods. 12, exit interlocking wind mechanism to prevent the formation of scale body negative pressure so that pulverized gravity. 13, return belt have tension device, automatically corrects the belt deviation. Five services: installation drawings, arrange on-site installation and commissioning guidance technician; 24-hour telephone service, service reach across the country within 48 hours
