Description
Technical Field
The invention relates to the field of waste gas dust removal, in particular to a dust-containing waste gas treatment device for an animal feed production plant.
Background
In a feed factory, waste gas generated in the production of feed contains a lot of dust, and the dust is filtered to be discharged, and a pulse dust removal mode is generally adopted. The dust removal efficiency of the novel filter material is not high enough in the dust removal method. After the filter material is used for a period of time, due to the effects of screening, collision, detention, diffusion, static electricity and the like, a layer of dust is accumulated on the surface of the filter bag, the layer of dust is called as a primary layer, in the later movement process, the primary layer becomes a main filter layer of the filter material, and the filter material with larger meshes can obtain higher filtering efficiency by virtue of the action of the primary layer. Along with the accumulation of dust on the surface of the filter material, the efficiency and the resistance of the dust remover are correspondingly increased, and when the pressure difference between two sides of the filter material is large, some fine dust particles attached to the filter material are extruded, so that the efficiency of the dust remover is reduced. In addition, the air volume of the dust removal system is significantly reduced due to the excessively high resistance of the dust remover. Therefore, the dust is removed in time after the resistance of the dust remover reaches a certain value. The initial layer cannot be damaged during ash removal, so that the efficiency is prevented from being reduced.
In patent document No. CN209076274U, it is proposed that the axial position of the pleated cloth bag is blocked differently during the re-filtration process, so that the pleated cloth bag cannot be opened according to the amount of dust accumulated on the pleated cloth bag when the dust outside the cloth bag is treated by the pulse, and the efficiency of cleaning the pleated cloth bag by the pulse air flow is reduced.

Particularly, the driven wheel 260 is sleeved with a blocking ring 270, the locking rod 280 is provided with a stop, and when the locking rod 280 moves downwards for a preset distance, the stop contacts with the blocking ring 270 to prevent the lower end of the locking from continuing to extrude the limiting groove 231, so that the rotation resistance of the second wheel 230 is prevented from being increased.
In this embodiment, as shown in fig. 4 to 7, the hydraulic cylinder 200 includes a cylinder body 201, a hydraulic pipe 202, and a connecting sleeve 180; the cylinder body 201 is filled with hydraulic oil, and one end of the cylinder body 201 is fixedly connected with the support ring 170; the hydraulic pipe 202 is inserted in the cylinder body 201 and fixedly connected with the bottom of the cylinder body 201; the hydraulic pipe 202 is communicated with the bottom of the cylinder 201; the first wheel 190 is rotatably sleeved on the hydraulic pipe 202; the inner push rod 210 can be axially slidably and hermetically inserted in the hydraulic pipe 202; the connecting sleeve 180 is positioned between the cylinder body 201 and the connecting sleeve 180, can axially slide and can be rotatably sleeved on the hydraulic pipe 202, and the connecting sleeve 180 is respectively in sealing contact with the cylinder body 201 and the connecting sleeve 180; the connecting sleeve 180 is fixedly connected with the first wheel 190.
During operation, dust-containing waste gas enters the lower cavity in the shell 110 from the ventilation pipeline, meanwhile, the waste gas impacts the baffle 113, and large-particle dust in the waste gas falls into the collecting cavity 150 directly after being filtered by the baffle 113. The process of the exhaust gas entering the upper chamber from the vent hole 112 is filtered by the pleated cloth bag 160, and then the exhaust gas is filtered, so that the filtered gas is discharged upwards from the exhaust port 130, and smaller dust is filtered by the pleated cloth bag 160. When the positions of the pleated cloth bags 160 are blocked differently, the permeability of the parts with serious blockage is reduced, and the larger the thrust from the exhaust gas is, the larger the moving amount of the support rod 241 moving towards the main shaft 250 is. The supporting rod 241 pushes the inner push rod 210 to move through the connecting rod 240, the inner push rod 210 increases the pressure inside the cylinder 201 through the hydraulic pipe 202, and then pushes the connecting sleeve 180 to slide towards the side far away from the main shaft 250, and the connecting sleeve 180 drives the first wheel 190 to move synchronously. The first wheel 190 slides along the radial direction of the driven wheel 260 to the side far away from the main shaft 250, so that the driven wheel 260 drives the transmission ratio of the first wheel 190 to increase. When the connecting rod 240 slides to one side of the main shaft 250 for a certain distance, it indicates that the cloth bag is blocked to a certain extent, at this time, a sensing part of the sensing assembly receives a signal, an electric signal of the sensing part is transmitted to the pressing part, the pressing part drives the driving wheel 310 to move downwards, the driving ring drives the locking ring 290 to move downwards at the same time, and then the locking rod 280 moves downwards and is inserted into the limiting groove 231, so as to achieve the effect of preventing the second wheel 230 from moving towards the direction away from the main shaft 250.
In the process that the driving wheel 310 moves downwards along the main shaft 250, the driving wheel 310 rotates under the action of the spiral groove of the main shaft 250, the driven wheel 260 is driven by the driving wheel 310 through the synchronous rod 330 to rotate, the driven wheel 260 drives the first wheel 190 to rotate through friction transmission, the first wheel 190 drives the second wheel 230 to rotate synchronously, and the second wheel 230 is locked by the locking rod 280 and cannot move along the radial direction of the main shaft 250, and the connecting rod 240 is fixedly connected with the supporting rod 241. Further, under the threaded engagement between the second wheel 230 and the connecting rod 240, the connecting rod 240 moves away from the main shaft 250 relative to the second wheel 230, and at this time, the pleated cloth bag 160 at that position is spread, and the area of the air flow generated by the pulse valve 350 is a little larger, whereas the area of the pulse valve 350 acting on the lightly blocked position is a little smaller. After the pulse valve 350 finishes cleaning the dust on the pleated cloth bag 160, the sensing assembly controls the driving wheel 310 to ascend through the pressing part, the supporting rod 241 and the adjusting wheel restore to the original positions, and the device restores to the original position for the next filtration.
