The second mode is that an underground round small pool is dug under each bag-type dust remover to be used as a slurry melting tank, fine powder of the dust remover is conveyed into the underground slurry melting tank by using a screw machine, and the fine powder is pumped into a slurry making pool in a ball milling workshop by using a plunger pump after slurry melting and is digested in a corresponding formula according to a certain proportion.
The above conventional dust collector further processing methods for absorbing and collecting dust have obvious disadvantages. Thus, the present invention provides a more efficient and energy efficient method of operation in place of the above-described fines treatment methods. The device can be used for directly recovering dry fine powder of a spray tower bag-type dust collector in the ceramic industry.
Referring to fig. 1, the dust removing and recycling apparatus for a spray tower provided by the present invention includes: a spray tower 100, and a dust collector 200 communicating with the spray tower 100. That is, the spray tower 100 and the dust collector 200 are communicated with each other, and the dust collector 200 can collect dust generated in the spray tower 100. The spraying tower 100 is provided with a discharge port 110, and a spraying conveyor belt 300 is arranged below the discharge port 110. The materials in the spray tower 100 are sprayed out from the discharge port 110 onto the spraying material conveyer belt 300 and are merged into a warehouse for use. A recovery material port 210 is arranged on the dust remover 200, and a fine powder conveying belt 400 is arranged below the recovery material port 210; the fine powder conveyer belt 400 is used for conveying the recovered fine powder in the dust collector 200 to the material spraying conveyer belt 300. The material spraying conveying belt 300 and the fine powder conveying belt 400 are controlled by an electric control system, and the electric control system comprises a frequency converter. The spraying conveyer belt 300 and the fine powder conveyer belt 400 may be 10m long and 400mm wide conveyer belts, and the spraying conveyer belt 300 and the fine powder conveyer belt 400 are connected with a first motor, and the power of the first motor is 2.2 kw.
Of course, the material in the spray tower 100 should be guaranteed to be the same formulation as the fine powder in the dust collector 200, and when the formulation in the spray tower 100 is changed, if the formulation in the dust collector 200 is still the same formulation, the fine powder in the dust collector 200 is not conveyed to the fine powder conveyer belt 400 and the injection conveyer belt 300.
Through the common experimental comparison of raw material and process, the fine powder below the bag-type dust collector 200 which is not polluted by other miscellaneous materials in the same formula is taken, and the fine powder is matched with pressure test according to the proportion of 3-7 percent, so that the size and thickness defects of the finished brick are not obviously influenced. Thus, the fine powder conveying belt 400 is directly manufactured below the recycling port 210 of the dust remover 200, and the fine powder with the same formula is directly conveyed to the spraying conveying belt 300 below the spraying tower 100 according to the proportion and put into a bin for use, so that the direct recycling is realized, the efficiency is high, the energy is saved, the speed is high, the environment is protected, the secondary dust raising is avoided, and the efficiency of recycling the fine powder is improved.

The bag-type dust collector 200 is a bag-type dust collector 200, which is a dry dust filter. It is suitable for trapping fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, the dust-containing gas is filtered by the filtering action of the fiber fabric, after the dust-containing gas enters the bag type dust collector 200, dust with large particles and large specific gravity falls into the dust hopper due to the sedimentation of the gravity, and when the gas containing fine dust passes through the filter material, the dust is blocked, so that the gas is purified. The settled fine powder is discharged to the fine powder conveyer 400 through the recovery material port 210 and the recovery material pipe 220.
Further, a discharging hopper 500 is arranged at one end of the fine powder conveying belt 400 close to the spraying conveying belt 300, and the discharging hopper 500 is arranged above the spraying conveying belt 300. That is, in order to smoothly transfer the fine powder on the fine powder conveyor 400 to the blasting conveyor 300, the lower hopper 500 is provided at one end of the fine powder conveyor 400 close to the blasting conveyor 300.
In one implementation, the dedusting recovery device is further provided with a screw machine 600 and a slurry pond 700; the dust remover 200 is provided with a slurry mixing port 230, and the slurry mixing port 230, the screw machine 600 and the slurry mixing tank 700 are communicated in sequence. The screw machine 600 is connected with a second motor, and the power of the second motor can be 4 KW.
Specifically, a set of screw machines 600 is installed below the dust collector 200, when the formulation is changed in the spray tower 100, the fine powder in the dust collector 200 cannot be recovered, and the fine powder is sent to the water pool for slurrying through the screw machines 600. The conversion formula refers to the conversion of the spray type, e.g., material a, to material B in the spray tower 100, so that the fine powder type also becomes material B. Because the formula is converted, the fine powder is also converted from the material A to the material B, the fine powder of the material A is remained in the dust remover 200, the fine powder cannot be recycled, and the residual fine powder of the material A needs to be discharged through the screw machine 600 to form slurry which is pumped out and subjected to ball milling. And after the fine powder is discharged for about 30 minutes, the fine powder is judged to be qualified.
Further, the dust removal recovery device further comprises: a dust collection air pipe; the material spraying conveying belt 300 is provided with a first dustproof shed 310, the fine powder conveying belt 400 is provided with a second dustproof shed 410, the first dustproof shed 310 is provided with a first dust suction pipe 311, the second dustproof shed 410 is provided with a second dust suction pipe 411, and the first dust suction pipe 311 and the second dust suction pipe 411 are connected with a dust suction air pipe. That is, in order to prevent secondary dust emission, a dust-proof shed is provided above the conveyor belt. And the dust raised on the conveyer belt is directly sucked into the dust suction air pipe through the first dust suction pipe 311 and the second dust suction pipe 411, so that the dust raising is avoided.
Further, a third dust suction pipe 510 is disposed on the discharging hopper 500, and the third dust suction pipe 510 is connected to the dust suction air pipe. That is, when the lower hopper 500 transfers the fine powder on the fine powder conveyer 400 to the material spraying conveyer 300, the dust is also raised, and the third dust suction pipe 510 is disposed on the lower hopper 500, so that the raised dust near the lower hopper 500 is sucked to the dust suction duct through the third dust suction pipe 510, thereby preventing the secondary raised dust.
Further, a first pneumatic valve 810 is disposed on the recycling port 210, and a second pneumatic valve 820 is disposed on the slurry melting port 230.
Specifically, when dust removal recovery is performed, the first pneumatic valve 810 is opened, and the fine powder falls onto the fine powder conveyor belt 400 through the recovery pipe 220 until the fine powder is conveyed onto the material spraying conveyor belt 300 through the discharging hopper 500. When it is desired to change formulations, the first pneumatic valve 810 is closed and the second pneumatic valve 820 is opened to deliver the fines to the sump via the auger 600 for slurrying. And when the conversion is finished and the fine powder is qualified and recyclable, closing the second pneumatic valve 820, opening the first pneumatic valve 810, conveying the powder to the material spraying conveying belt 300 by the fine powder conveying belt 400, controlling the rotating speed of the belt by the frequency of the belt frequency converter, and conveying the powder to a storage bin according to the proportion of about 7 percent for recycling.
In one implementation, the spray tower 100 is arranged in parallel with the dust remover 200, the fine powder conveyer belt 400 is arranged between the spray tower 100 and the dust remover 200, and the height of the fine powder conveyer belt 400 near one end of the dust remover 200 is lower than that near one end of the spray tower 100. Thus, the fine powder is conveyed to a high place, and the dust emission can be further reduced.
In one implementation manner, one end of the spraying conveyor belt 300, which is away from the fine powder conveyor belt 400, is communicated with a feed bin, and the height of the spraying conveyor belt 300, which is close to one end of the fine powder conveyor belt 400, is lower than that of the other end. Similarly, the fine powder and the materials are simultaneously conveyed to a high place, and the dust emission is further reduced.
Further, the dust remover 200 is also communicated with a spray tower 900, and the spray tower 900 is used for secondary dust removal. The spray tower is a secondary dust removal device of the whole spray tower system, so that the dust collector is prevented from being damaged and the discharged dust exceeds the standard.
The dust removal recovery device can solve the problem of secondary dust pollution caused by serious secondary dust emission caused by the original dry powder recovery ball milling feeding recovery method. The problem that the pressure of sewage treatment is increased by ball milling and feeding in an old wet method slurry and sewage recovery pool can be solved; the method for conveying the fine powder of the dust remover 200 to an underground slurry melting tank by using the screw 600 and pumping the fine powder into a slurry making tank in a ball milling workshop by using a plunger pump after melting slurry is improved compared with the two methods, but the problems that the power consumption of repeated ball milling in the ball milling workshop is increased and the coal consumption of repeated material spraying of the spray tower 100 is increased are also caused. After the dry recovery method is used, the energy consumption of recovering the fine powder to ball milling for repeated grinding, stirring and spraying can be greatly saved. The proportion of fines was about 8% at a yield of 14000 column 40T/h. Coal consumption is 60KG/T powder, and ball milling power consumption is 46 degrees/material. Calculated according to 330 days of tower opening all the year round, coal consumption 1748T is saved by about 141 ten thousand yuan per year, and electricity consumption 116 is saved by about 70 ten thousand yuan per year. The labor cost for transferring fine powder and the addition amount of auxiliary materials for sewage treatment are reduced by about 10 ten thousand yuan per year, the total saving amount of 327 yuan per year is estimated, and the economic benefit is greatly improved.
