Description

Technical Field

[0001] The utility model relates to the technical field of pulse dust collectors, in particular to a pulse dust collector for storing raw grains in feed production. Background Art

[0002] A pulse dust collector is a device used to collect and filter dust in the industrial production process, and is widely used in various industries, including feed production, mining, metallurgy, chemical industry, etc. It is favored for its high dust removal performance and low operating cost. In the process of storing and processing feed raw grains (such as unloading, conveying, mixing, etc.), a large amount of dust is inevitably generated. Dust not only affects environmental hygiene, but may also pose a hazard to the health of equipment and operators. A large amount of dust will form "secondary pollution" in the storage area and production area, and an effective dust removal device is needed to maintain the hygiene and safety of the working environment. Using a pulse dust collector can reduce the damage of dust to equipment, reduce equipment failures and shutdowns caused by dust, and will help improve production efficiency.

[0003] After retrieval, a pulse feed dust collector with the publication number of CN208893815U includes a dust collector housing, a card slot and a purification chamber. A slag outlet is installed at the bottom of the dust collector housing, and an air inlet is arranged on the left side of the dust collector housing. A sealing rubber tube is installed inside the air inlet, and a fixing spring is arranged on the outer side of the sealing rubber tube. A filter bag is arranged inside the dust collector housing, and brushes are installed on both the left and right sides of the filter bag. A fixing plate is fixed at the top of the filter bag, and a tooth block is installed on the outer side of the fixing plate. This pulse feed dust collector is provided with a tooth block and a rotating gear. The motor drives the bevel gear to rotate, so that the bevel gear drives the connecting rod and the rotating gear to rotate together. Thus, the rotation of the rotating gear drives the tooth block on the outer side of the fixing plate to move, so that the fixing plate drives the two filter bags to rotate, so as to facilitate the filter bags to filter the air inside the whole device well and improve the efficiency of the whole device.

[0004] For the above-mentioned publicly disclosed pulse dust collector, the air entering the filter bag for dust cleaning is extracted from the air around the working environment. If the air temperature is too high or too humid, it is easy to cause the filter bag to deform, damage, age, and caking on the filter bag. If the air temperature is relatively low, condensed water is likely to form on the surface of the filter bag, resulting in the filter bag being wet, thereby reducing the filtration efficiency, causing dust adhesion, and affecting the dust cleaning effect. At the same time, the filter bag will become more fragile at low temperature and is prone to breakage. Whether it is low temperature or high temperature, if the temperature difference between the air used and the temperature of the environment where the filter bag is located is too large, it will have a negative impact on the dust cleaning effect. Content of the Utility Model

[0005] In view of the technical problem that in the existing patents, for the existing pulse dust collector, the temperature and humidity of the gas ejected during the dust cleaning of the filter bag cannot be regulated, and affected by the temperature and humidity of the gas, the filter bag is prone to caking, damage and aging, and the filtering efficiency of the filter bag is easily reduced, the utility model provides a pulse dust collector for storing raw grains in feed production.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] The following is a further description of the present utility model in conjunction with the attached Figures 1-3 drawings.

[0023] In order to solve the problems existing in the background art, the present application proposes the following technical solution: a pulse dust collector for storing raw grains in feed production.

[0024] In the specific technical solution, it includes a dust removal shell 1 and an anti-frost component 3. One side of the dust removal shell 1 is fixed with an air bag 2, and a dust hopper is fixed below. The air bag 2 is used to store compressed air to provide an instantaneous high-pressure air flow when the filter bag 7 needs to be cleaned, ensuring that there is sufficient air pressure during the cleaning process to effectively backwash the dirt and dust accumulated on the filter bag 7. The dust hopper is used to collect the dust after the filter bag 7 is cleaned of dust, facilitating subsequent treatment and discharge. A plurality of blow pipes 5 are fixed inside the dust removal shell 1, and a plurality of electromagnetic pulse valves 6 are fixed outside the dust removal shell 1. The electromagnetic pulse valves 6 are used to control the release of the compressed air in the air bag 2 through the blow pipes 5 to perform periodic pulse cleaning of the filter bag 7, ensuring that the filter bag 7 can maintain a good filtering effect. A plurality of electromagnetic pulse valves 6 are respectively connected to one end of a plurality of blow pipes 5, and a plurality of electromagnetic pulse valves 6 are all connected to the air bag 2 through air pipes. A plurality of filter bags 7 are arranged inside the dust removal shell 1.

[0025] An air inlet is provided on one side of the dust removal shell 1, connected to an intake pipeline, and an air outlet is provided on the other side, connected to an outlet pipeline. The contaminated gas first enters the dust removal shell 1 through the air inlet. When the gas passes through the filter bag 7, the dust particles are captured on the surface of the filter bag 7. As the filtering process progresses, more and more dust will gradually accumulate on the surface of the filter bag 7, resulting in an increase in the resistance of the filter bag 7. The pulse dust collector is equipped with a pressure sensor to monitor the resistance value of the filter bag 7 to determine whether the filter bag 7 needs to be cleaned. When cleaning, the electromagnetic pulse valve 6 opens the valve, and the high-pressure air stored in the air bag 2 will be quickly released through the solenoid valve. The high-pressure air flow jets rapidly into the interior of the filter bag 7 along the blow pipe 5, forming a strong reverse impact air flow, shaking off the dust particles accumulated on the filter bag 7. The dust falls into the dust hopper, and the filter bag 7 can continue to be used normally.

[0026] The anti-frost component 3 is arranged on one side of the air bag 2 to control the temperature and preliminarily dehumidify the air entering the air bag 2, preventing the air with high temperature, low temperature or high humidity from causing deformation, aging or reducing the service life of the filter bag 7 material, and affecting the filtration effect. The anti-frost component 3 includes a temperature and humidity control component, which is used to control the temperature and humidity of the gas entering the air bag 2. The temperature and humidity control component includes a hollow cooling tank 31 and a heating tank 32. The hollow cooling tank 31 cools the high-temperature air, and the heating tank 32 heats the low-temperature air. Condensate may form on the surface of the filter bag 7 with low-temperature air, causing the filter bag 7 to become wet, thereby reducing the filtration efficiency and affecting the dust cleaning effect. The filter bag 7 of some materials will become more fragile at low temperature and is prone to breakage, while high temperature will cause the filter bag 7 to deform and accelerate the aging process of the filter bag 7 material (such as polyester fiber, etc.), shortening the service life. A spiral cooling pipe 33 is fixed inside the hollow cooling tank 31. A semiconductor refrigeration sheet 34 and a water pump 35 are arranged inside the hollow cooling tank 31. A water suction pipe is fixed at the water inlet end of the water pump 35, and the water outlet end of the water pump 35 is communicated with one end of the spiral cooling pipe 33. The other end of the spiral cooling pipe 33 extends into the hollow cavity of the hollow cooling tank 31 to realize water circulation. A heating wire 36 is arranged inside the heating tank 32. A three-way inlet pipe 37 is fixed above the hollow cooling tank 31 and above the heating tank 32. A moisture absorption sheet 38 is arranged above the three-way inlet pipe 37. The moisture absorption sheet 38 can be made of silica gel or activated carbon. A three-headed connecting pipe is connected below the hollow cooling tank 31 and the heating tank 32. Solenoid valves are arranged at the pipe ends of the three-headed connecting pipe, the heating tank 32 and the hollow cooling tank 31. A temperature sensor is arranged inside the three-headed connecting pipe to judge whether the entering air is high temperature or low temperature. The high temperature value and the low temperature value are set in advance in the controller. If the temperature value belongs to high temperature, the air is sent into the hollow cooling tank 31 through the three-headed connecting pipe, otherwise, it is sent into the heating tank 32.

[0027] The anti-frost component 3 further includes a replacement part, which is arranged above the three-way intake pipe 37 and is used to replace the moisture absorption sheet 38 that needs to be replaced. The replacement part includes a connecting pipe 39 and an internally threaded closing pipe 310. One end of the connecting pipe 39 is fixed to one side of the air bag 2, and the internally threaded closing pipe 310 is fixed to the outside of the three-way intake pipe 37. The outer thread of the connecting pipe 39 is threadedly connected with an installation pipe 311, and a plurality of assisting rods 4 are fixed to the outside of the installation pipe 311 to facilitate applying force when rotating the installation pipe 311. A groove 312 is formed below the installation pipe 311, and a clamping groove 313 is formed on the inner surface of the groove 312. The moisture absorption sheet 38 is clamped inside the groove 312. An annular retaining ring 314 is arranged inside the groove 312, and a force-applying strip is arranged in the middle of the annular retaining ring 314, which facilitates pulling the annular retaining ring 314 out of the groove 312. Elastic clamping strips 315 are fixed to the outer surface of the annular retaining ring 314, and the elastic clamping strips 315 are clamped inside the clamping groove 313. The annular retaining ring 314 is fixed in the groove 312 by using the elastic clamping strips 315 to fix the moisture absorption sheet 38.

[0028] For those skilled in the art to fully understand the technical solution, the following is an overall overview of this application:

[0029] During use, before the air enters the air bag 2, it is judged whether the air is high temperature or low temperature according to the temperature sensor. If the temperature value belongs to high temperature, the air is sent into the hollow cooling tank 31 through the three-way connecting pipe. The semiconductor refrigeration sheet 34 cools the water source stored in the hollow cooling tank 31 to the set temperature, and the water pump 35 pumps the low-temperature water into the spiral cooling pipe 33. The air is cooled through the spiral cooling pipe 33 to prevent the high-temperature air from being sprayed into the filter bag 7 later, and to avoid the deformation, damage and aging of the filter bag 7 under high-temperature conditions. If the temperature value belongs to low temperature, the air is sent into the heating tank 32 through the three-way connecting pipe, and the heating wire 36 is turned on to heat the passing low-temperature air to prevent the low-temperature air from being sprayed into the filter bag 7 later, and to avoid the formation of condensed water on the surface of the filter bag 7, resulting in the wetting of the filter bag 7, thereby reducing the filtration efficiency, preventing the adhesion of dust outside the filter bag 7 caused by the condensed water from affecting the dust cleaning effect, and preventing the filter bag 7 from becoming more fragile and easily damaged at low temperature. By reducing the temperature of the high-temperature air, the condensation of moisture can be promoted, and the moisture in the air can be effectively removed. When the low-temperature air is heated, the relative humidity in the air decreases, reducing the possibility of condensation. Appropriately heating and cooling the air can achieve a more efficient dehumidification effect. The temperature-controlled air passes through the three-way intake pipe 37 and the connecting pipe 39, and is secondarily dehumidified by the moisture absorption sheet 38 and then enters the air bag 2, fully reducing the humidity in the air and preventing the temperature of the air sprayed from the blowing pipe 5 from being too high, too low or too humid during the dust cleaning of the filter bag 7, resulting in the formation of lumps of dust adhering to the filter bag 7 and reducing the filtration effect of the filter bag 7.

[0030] For the replacement of the moisture absorption sheet 38, the installation pipe 311 can be rotated by the assist rod 4 to move it upward until the installation pipe 311 is screwed out of the internally threaded closing pipe 310. After the annular retaining ring 314 is exposed, the annular retaining ring 314 is pulled out of the groove 312 by using the force application strip, and the moisture absorption sheet 38 will fall out. Place the new moisture absorption sheet 38 on the annular retaining ring 314 and put them into the groove 312 together. Press the annular retaining ring 314 until the elastic clamping strip 315 snaps into the clamping groove 313 to fix the position of the annular retaining ring 314. Rotate the installation pipe 311 again until one end of the installation pipe 311 is screwed into the internally threaded closing pipe 310, and the replacement of the moisture absorption sheet 38 can be completed. The replacement method of the moisture absorption sheet 38 is fast and convenient.
