Abstract
The invention relates to a stone coal collecting and conveying system, which is used for collecting and conveying stone coal generated by coal mills in a coal pulverizing system in coal-based power plants, and belongs to the technical field of accessory units of the coal mills. For improving the conventional manual conveying, hydraulic conveying and negative pressure conveying of the stone coal, a stone coal bidirectional collecting device is arranged above a conveyer belt of a belt conveyor. Therefore, no leakage for the primary air pressure can be guaranteed. The problem of transport of emergent manual stone coal for rush repair of a transmitting device is solved. The environmental pollution is controlled, and healthy production is guaranteed. A phenomenon of erosive wear of the equipment is substantially absent; the energy consumption is low, and the efficiency is high. The whole system automatically works, has no blockage phenomenon and low maintenance workload under the action of related control circuits. The system capacity is high; the safe operation of the set is effectively guaranteed; the production reliability and production efficiency are effectively improved; and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of stone coal collecting and conveying system, be used for the collection and the conveying of the stone coal of thermal power plant's pulverized coal preparation system coal mill generation, belong to coal mill corollary apparatus technical field.
Background technology
The stone coal processing mode of power plant's application has at home at present: artificial treatment, waterpower conveying, strength conveying etc.The artificial treatment work capacity is big, labour intensity big, the environmental pollution health care is poor; The easy coking plugging of stone coal that waterpower is carried, increasing hydraulic pressure back part is impaired can not to solve the plugging problem, and equipment attrition is serious, and water consumption is big, and efficient is low; Strength is carried can only use negative pressure at present, undercapacity, and especially iron wire can cause plugging, and feeder and air pressure accelerating chamber fault rate are also very high, and the wearing and tearing of pipeline are also quite serious.Above-mentioned many deficiencies bring very big inconvenience for design and safety in production, the variation of the stone coal amount that especially produces because of the variation of coal in thermal power plant, and the adaptive capacity of system is poor.
Summary of the invention
The purpose of this invention is to provide a kind of stone coal collecting and conveying system, solve the above-mentioned many deficiencies that exist on the existing stone coal processing mode, anti-blocking, the undercapacity, equipment attrition, the operating maintenance work capacity that solve the stone coal collecting course of conveying by the present invention effectively are big, thereby guarantee the safe operation of pulverized coal preparation system.
The objective of the invention is to be achieved through the following technical solutions, a kind of stone coal collecting and conveying system, comprise the sending set of forming by the load-transfer device on belt feeder, the belt feeder, it is characterized in that, the top of sending set is provided with the two-way gathering-device of stone coal, the load-transfer device on the corresponding belt feeder of the outlet of the transition segment in the two-way gathering-device of stone coal.
The two-way gathering-device of described stone coal is by the middle bucket that pneumatic insertion plate door is set, set out the feed collecting box of bin gate, the Pneumatic three-way of the discharging opening of middle bucket, the inlet point captive joint of feed collecting box, the case that artificially collects that the end opening bonded assembly transition segment of feed collecting box discharge door and another mouthful of Pneumatic three-way below are provided with constitutes.
The top of feed collecting box is provided with high temperature level-sensing device and blow off valve.
Along load-transfer device one side alternate some spray equipments are set, an end of belt feeder is provided with feed bin.
Load-transfer device adopts high temperature resistant steel band.
The present invention is the improvement of existing stone coal being adopted artificial conveyance, waterpower conveying, negative pressure transportation, by the two-way gathering-device of stone coal is set on the load-transfer device of belt feeder, can guarantee that a wind blast does not have leakage; Solved the transhipment of the emergent artificial stones coal of sending set repairing; Control environmental pollution, ensured healthy production; Substantially do not have equipment erosive wear phenomenon, power consumption is low, efficient is high; Under the effect of relevant control circuit, total system automatic operating, no latch up phenomenon, maintenance load are low; System's height of exerting oneself has effectively ensured the safe operation of unit, effectively improves production stability and production efficiency, has reduced productive costs.
Description of drawings
Fig. 1 is the invention structural representation;
Among the figure, 1 pneumatic insertion plate door, bucket in 2,3 feeding gates, 4 Pneumatic three-ways, 5 artificially collect case, 6 feed collecting boxs, 7 discharge doors, 8 transition segments, 9 load-transfer devices, 10 spray equipments, 11 blows off valve, 12 high temperature level-sensing devices.
The specific embodiment
Further specify the present invention in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, system is made up of gathering-device and sending set.Gathering-device successively the pneumatic insertion plate door 1 of bonded assembly, middle bucket 2, feeding gate 3, Pneumatic three-way 4, artificially collect case 5, feed collecting box 6, discharge door 7, transition segment 8, blow off valve 11, high temperature level-sensing device 12 and form; Sending set is made up of belt feeder, load-transfer device 9, spray equipment 10, feed bin etc.A generator set grinding machine is provided with some gathering-devices, and a generator set grinding machine overlaps sending set with one.When sending set was rushed to repair, Pneumatic three-way inserted and artificially collects case 5.Be provided with high temperature level-sensing device 12 in the feed collecting box 6.
The collection work flow process is: open pneumatic insertion plate door 1, the stone coal enters middle bucket 2.During normal operation, Pneumatic three-way 4 leads to feed collecting box 6 positions, opens feeding gate 3, and the stone coal enters feed collecting box 6, and is to be sent according to router etc.When receiving the transmission signal, close feeding gate 3, open blow off valve 11 releases, open discharge door 7 after the release, the stone coals in the feed collecting box 6 are discharged on the load-transfer device 9 through transition segment 8 and carry.When sending set is rushed to repair, Pneumatic three-way 4 led to artificially collect case 5 positions, open feeding gate 3, the stone coal enters and artificially collects case 5, regularly cleaning after the release.
The transmission workflow is: when load-transfer device 9 is zero load, open the discharge door 7 of each group simultaneously, stone coal in the feed collecting box 6 is discharged on the load-transfer device 9 equably.According to the operating speed of load-transfer device 9, set dumping time, the stone coal that makes a mill draw off arrives till next mill, the stone coal for the treatment of last mill in the past after, discharging once more.If then preferentially carry when the level-sensing device on the feed collecting box 6 is reported to the police.Conveying at load-transfer device 9 is provided with some spray equipments 10 on the way, and automatic spray makes the cooling of stone coal and prevents airborne dust.
Pneumatic insertion plate door 1 among the present invention, discharge door 7, Pneumatic three-way 4 are existing product, and pneumatic insertion plate door 1, discharge door 7 generally use in the grey storehouse or electric dust collector of thermal power plant.
