Description
Technical field
The utility model relates to a kind of exhaust system, refers to especially a kind of removing gangue system of medium-speed pulverizer.
Background technology
At present, the pebble coal treatment system is divided into usually: three kinds of waterpower, machinery and artificial conveyance, to apply all very generally, and three kinds of different systems, have respectively again many variations, and various schemes are multifarious, and the characteristics of oneself are respectively arranged.These modes are mostly external introduction, and good operational performance is arranged abroad, but domestic result of use is not good.Tracing it to its cause, is mainly that external fire coal species is single, ature of coal is well the marketable coal of treated mistake, thereby the pebble coal amount is few and fluctuate little; Domestic power plant soot coal is changeable, ature of coal is poor and unprocessed, and pebble coal is the many and situation of vary within wide limits (number differs and can reach tens times) with regard to the amount of presenting.
The Hydraulic Transportation System complexity, operational efficiency is low, and expense is high, adjusts running-in period long, and fed distance is short, and the bulk obstruction of collection bucket, turn one's coat, and the situations such as the sewage leakage of pump valve are difficult to avoid, and these problems have also proposed challenge to the operation and management level of power plant.Move in bad situation, site environment allows of no optimist.The machinery mode of movement, subterranean tunnel boiler room in is absolutely necessary, and always has one or two conveyers need be arranged in underground confined space, and maintenance workload is large, and it is large to overhaul difficulty.Subterranean tunnel domestic demand design dedusting, flushing, drainage, initial investment is large.In addition, most of system also needs to arrange climbing conveyer, makes troubles to integral arrangement and operation after stove in after taking stove or position, furnace side.Mainly there are two problems in the artificial conveyance system, and the one, site environment pollutes, and the guarantee of operating worker occupational health is poor; The 2nd, labour intensity is large.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of removing gangue system of medium-speed pulverizer, to solve the drawback of prior art.
For solving the problems of the technologies described above, the utility model embodiment provides a kind of removing gangue system of medium-speed pulverizer, comprise medium-speed pulverizer, the deslagging outlet of described medium-speed pulverizer is connected with passage, the outlet of the lower end of described passage is connected with gas-tight silo, and described gas-tight silo is arranged on mobile bucket top, and described the movement below struggling against is provided with weighing platform, described passage is provided with the secondary valve lock, described secondary valve lock and gas-tight silo switch interlocking.
Wherein, the deslagging exit of described medium-speed pulverizer is provided with the one-level gate valve.
Wherein, described removing gangue system comprises the fork truck suitable with described mobile bucket.
Wherein, described weighing platform is provided with the gravity sensitive system.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, lowered the coal pulverizer maintenance workload, saved water, the electric energy consumption of auxiliary group of equipment, improved the stone coal discharge working environment, safeguarded that coal pulverizer normally moves.Improve mobile stone coal bunker, improved mechanization degree, alleviated labor strength, solved the sealing problem in the discharging engineering, reduced the environmental pollution that Workplace is caused.

The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model, for the drawback of prior art, provides a kind of removing gangue system of medium-speed pulverizer.
As shown in Figure 1, the removing gangue system of the utility model embodiment medium-speed pulverizer, comprise medium-speed pulverizer, the deslagging outlet 1 of described medium-speed pulverizer is connected with passage 2, the deslagging of described medium-speed pulverizer exports 1 place and is provided with one-level gate valve 6, and described one-level gate valve 6 is service valve, when system is normally moved, all the time open, just close while needing maintenance secondary gate valve 7; Described passage 2 is provided with secondary valve lock 7, the enclosed switch interlocking of described secondary valve lock 7 and gas-tight silo 3, and when secondary gate valve 7 is opened, the console switch of gas-tight silo 3 is unaffected, and gas-tight silo 3 keeps the sealing states can not pressure release; The lower end outlet of described passage 2 is connected with gas-tight silo 3, described gas-tight silo 3 is arranged on mobile bucket 4 tops, both sealings are good, prevent that dust from emitting contaminated environment outward, described mobile bucket 4 is equipped with suitable with it fork truck, and described mobile the bucket is provided with weighing platform 5 below 4, and described weighing platform 5 is provided with the gravity sensitive system, after the weight of mobile bucket 4 reaches weighing platform 5 setting values, the gravity sensitive system is sent warning.
The whole system workflow is as follows:
Start medium-speed pulverizer and open one-level gate valve 6 and secondary gate valve 7, pebble coal flows out from deslagging outlet 1, through passage 2 and gas-tight silo 3, enter in mobile bucket 4, after the weight of mobile bucket 4 reaches weighing platform 5 setting values, the gravity sensitive system is sent while reporting to the police, close secondary gate valve 7, sound all clear, the console switch in opening encapsulation storehouse 3, gas-tight silo 3 pressure releases depressurization, start fork truck, the mobile bucket 4 of transportation, be poured over assigned address by pebble coal, will move bucket 4 and be classified as, close the console switch of gas-tight silo 3, open secondary gate valve 7.
In such scheme, lowered the coal pulverizer maintenance workload, saved water, the electric energy consumption of auxiliary group of equipment, improved the stone coal discharge working environment, safeguarded that coal pulverizer normally moves.Improve mobile stone coal bunker, improved mechanization degree, alleviated labor strength, solved the sealing problem in the discharging engineering, reduced the environmental pollution that Workplace is caused.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
