Abstract
The utility model relates to a kind of coal dust recovery system sundries cleaning device, comprise the sack cleaner be connected with coal dust input channel, two dedusting coal powder collection casees that sack cleaner is connected therewith successively, two coal dust output channels, unloading valve, coal store and ring balance claim, it is characterized in that above star-shaped dust-discharging valve, square hole dusting cover being installed respectively in described two dedusting coal powder collection casees, and sidewall above two dedusting coal powder collection case square hole dusting covers has manhole door, the sidewall of two dedusting coal powder collection case manhole door 12 correspondences is respectively equipped with resistance pendulum level-sensing device.The utility model has the advantages that: efficiently avoid and cause ring balance pulverized coal scale to be blocked to cause stopping production accident owing to entering foreign material in Pulverized Coal Bin.Stop because the coal dust in the dedusting coal powder collection case caused that comes off of the cloth bag in the deduster of top accumulates too high simultaneously, caused negative pressure in cloth bag case to disappear and the fire that occurs and explosion accident.
Description
Technical field
The utility model belongs to dust recovery technology field, particularly relates to a kind of coal dust recovery system sundries cleaning device.
Background technology
Pelletizing plant adopts chain grate-rotary kiln method to produce oxide pellet, and the coal dust produced by coal-making system at whole production system heat energy used provides.Wherein grinding machine is the key equipment of coal-making system, can the production coal dust of stability and high efficiency, is ensure that chain grate-rotary kiln method produces the prerequisite of oxide pellet production efficiency.
Existing coal making process system production process is: raw coal is rendered to grinding machine from coal yard by conveyer belt, under grinding machine grinds to form-200 mesh sieves 80% coal dust, through sack cleaner, the coal dust after grinding is absorbed dedusting coal powder collection case, then control to enter Pulverized Coal Bin through unloading valve from dedusting coal powder collection case.Pulverized Coal Bin bottom connects the consumption that ring-type balance weighing apparatus controls coal dust.
Because raw coal is mixed with the foreign material such as a large amount of wood, rag, plastics, beverage bottle in the process coals such as transport, storage.Foreign material often will enter grinding machine with raw coal and be ground into the sheet foreign material that leaf differs in size and enter Pulverized Coal Bin with coal dust, coal dust blocks by causing ring balance pulverized coal scale during ring balance pulverized coal scale, cause and stop for coal dust accident completely, in addition because the cloth bag in sack cleaner can block dedusting coal powder collection case because wearing and tearing come off, cause coal dust in dedusting coal powder collection case to pile up too high, cause negative pressure in cloth bag case to disappear and the fire of generation or explosion accident.
Summary of the invention
The utility model provides foreign material in a kind of bug dusting storehouse fast, stop the cleaning plant that pulverized coal scale is blocked, improve the running efficiency of coal powder injection equipment, ensure equipment safety operation in coal-grinding process, stop the coal dust recovery system sundries cleaning device of fire and explosion accident.
The purpose of this utility model is realized by following technical proposals.
Coal dust recovery system sundries cleaning device of the present utility model, comprise the sack cleaner be connected with coal dust input channel, two dedusting coal powder collection casees that sack cleaner is connected therewith, two the coal dust output channels be connected with described two dedusting coal powder collection casees respectively, be separately positioned on the unloading valve of junction on two dedusting coal powder collection casees and two coal dust output channels, the coal store be connected with described two coal dust output channels claims with the ring balance being arranged on coal store bottom, it is characterized in that above star-shaped dust-discharging valve, square hole dusting cover being installed respectively in described two dedusting coal powder collection casees, and sidewall above two dedusting coal powder collection case square hole dusting covers has manhole door, the sidewall that two dedusting coal powder collection case manhole doors are corresponding is respectively equipped with resistance pendulum level-sensing device.
The utility model is provided with sub-feed tube at described two between dedusting coal powder collection case and coal store, and described sub-feed tube one end is communicated with dedusting coal powder collection lower box part sidewall, and the other end is communicated with Pulverized Coal Bin top, and described sub-feed tube is also provided with push-pull valve.
The utility model has the advantages that: owing to have employed said structure, in dedusting coal powder collection case, be provided with square hole dusting cover, efficiently avoid and cause ring balance pulverized coal scale to be blocked to cause stopping production accident owing to entering foreign material in Pulverized Coal Bin.Stop because the coal dust in the dedusting coal powder collection case caused that comes off of the cloth bag in the deduster of top is hoarded too high simultaneously, caused negative pressure in cloth bag case to disappear and the fire that occurs and explosion accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Detailed description of the invention of the present utility model is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, coal dust recovery system sundries cleaning device of the present utility model, comprise the sack cleaner 1 be connected with coal dust input channel, two dedusting coal powder collection casees 2 that sack cleaner 1 is connected therewith, two the coal dust output channels 6 be connected with described two dedusting coal powder collection casees 2 respectively, be separately positioned on the unloading valve 5 of junction on two dedusting coal powder collection casees 2 and two coal dust output channels 6, the coal store 9 be connected with described two coal dust output channels 6 and the ring balance being arranged on coal store 9 bottom claim 10, it is characterized in that above star-shaped dust-discharging valve 5, square hole dusting cover 4 being installed respectively in described two dedusting coal powder collection casees 2, and sidewall above two dedusting coal powder collection case square hole dusting covers 4 has manhole door 11, the sidewall of two dedusting coal powder collection case manhole door 11 correspondences is respectively equipped with resistance pendulum level-sensing device 3.In dedusting coal powder collection case, be provided with square hole dusting cover, and on two dedusting coal powder collection casees, be provided with resistance pendulum level-sensing device 3 respectively, efficiently avoid and cause ring balance pulverized coal scale to be blocked to cause stopping production accident owing to entering foreign material in Pulverized Coal Bin.
Simultaneously for avoiding in coal-grinding process because foreign material are too much, blocking rectangular mesh, causing a large amount of coal dust to be accumulated in sack cleaner 1 makes negative pressure disappear, there is Peng Cang and fire incident, the utility model is provided with sub-feed tube 8 between described two dedusting coal powder collection casees 2 and coal store 9, described sub-feed tube 8 one end is communicated with dedusting coal powder collection case 2 lower sides, and the other end is communicated with Pulverized Coal Bin 9 top, and described sub-feed tube 8 is also provided with push-pull valve 7.The resistance pendulum level-sensing device of setting of the present utility model, coal dust is once too high and alarm, and grinding machine is stopped in time in post, opens push-pull valve, lays down coal dust in run coal bin, the foreign material on manhole door process sieve, after coal dust is emptying, starts grinding machine, continues coal-grinding.
