Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a waste gas collection device for feed processing. Background Technology

[0002] Feed is a general term for the food of animals raised by all people. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. Feed processing requires a waste gas collection device for feed processing.

[0003] Existing exhaust gas collection devices suffer from poor collection and treatment effects, allowing exhaust gases to diffuse freely within the space, resulting in high dust levels, especially in cold weather, and significant fogging. Furthermore, existing devices have several drawbacks. They require high overall sealing, which current devices lack, making leaks more likely. Regular cleaning of the primary filter is inconvenient, leading to clogging and rendering the device unusable. Finally, existing devices typically lack the ability to centrally process collected dust, increasing the risk of clogging in the main duct and reducing product recovery rates. Utility Model Content

[0004] The purpose of this utility model is to provide a waste gas collection device for feed processing, so as to solve the problems mentioned in the background art, such as the need to further improve the sealing performance of the waste gas collection device during use, the inconvenience of cleaning the surface of the first filter screen, and the lack of the function of centralized processing of collected powder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas collection device for feed processing, comprising a device base, a fixed box mounted on the surface of the top position of the device base, an air suction pump installed inside the fixed box, the input end of the air suction pump penetrating through the fixed box and extending to the outside of the fixed box, a main air duct arranged above the fixed box, a control button mounted on the surface of the main air duct, the input end of the air suction pump being electrically connected to the output end of the control button, an air inlet pipe mounted above the main air duct by screws, and a first filter screen for filtering and treating waste gas arranged inside the main air duct.

The surface of the collection frame and the inner wall of the collection box are equipped with a centralized collection mechanism. The centralized collection mechanism includes rotating balls, a roller groove, and a centralized collection component.

[0006] Preferably, a second filter screen is installed inside the main air duct, and a mesh plate is installed inside the main air duct, with the mesh plate located below the second filter screen. A pump body is installed inside the housing, with the input end of the pump body electrically connected to the output end of the control button. The output end of the pump body passes through the collection box and extends into the interior of the collection box. A fixing pipe is installed at the input end of the pump body, and a suction pipe is installed on the surface of the fixing pipe by screws. One end of the suction pipe passes through the main air duct and extends into the interior of the main air duct. The suction pipe is located above the mesh plate, and a valve is fitted on the surface of the suction pipe. The input end of the valve is electrically connected to the output end of the control button.

[0007] Preferably, the inner wall of the main air duct is equipped with a sealing frame, and a sealing gasket is provided inside the sealing frame. One end of the sealing gasket extends to the outside of the sealing frame and contacts the inner wall of the air pump. The inner wall of the sealing frame is provided with a guide groove, and the guide groove slides in cooperation with the surface of the sealing gasket.

[0008] Preferably, each of the sealing frames is equipped with equally spaced telescopic columns, one end of which is fixed to the surface of the sealing gasket. Each of the sealing frames is also equipped with equally spaced sealing springs, one end of which is fixed to the surface of the sealing gasket.

[0009] Preferably, the easy-cleaning assembly is disposed on the surface of the first filter and the inner wall of the air inlet pipe. The easy-cleaning assembly consists of a fixing groove, a fixing block and an anti-detachment clip. Fixing blocks are installed on both sides of the first filter, and fixing grooves are provided on the inner wall of the air inlet pipe. The surfaces of the fixing groove and the fixing block slide against each other.

[0010] Preferably, the inner wall of the air inlet pipe is equipped with a first magnet, and the surface of the bottom position of the first filter screen is equipped with a second magnet. The surfaces of the second magnet and the first magnet are magnetically attracted to each other. The surface of the fixing block is equipped with an anti-loosening clip for preventing the first filter screen from loosening. The anti-loosening clip is engaged with the inner wall of the air inlet pipe.

[0011] Preferably, the centralized collection component is disposed on the surface of the collection frame and the inner wall of the collection box. The centralized collection component is composed of a slider and a groove. Sliders are installed on both sides of the collection frame, and grooves are provided on the inner wall of the collection box. The grooves and the surfaces of the sliders slide against each other.

[0012] Preferably, the bottom surface of the collection box is provided with equally spaced roller grooves, and the surface of the roller groove is provided with rotating balls. The rotating balls rotate and cooperate with the inner wall of the roller groove, and the surface of the rotating balls contacts the inner wall of the collection box.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the waste gas collection device for feed processing not only improves the overall sealing performance of the waste gas collection device during use, avoiding waste gas leakage during use, but also makes it convenient for users to pull out the first filter screen from the inside of the main air duct and clean its surface, preventing the waste gas collection device from becoming unusable due to surface blockage of the first filter screen. Furthermore, the waste gas collection device can concentrate and collect powder together, reducing the phenomenon of blockage on the surface of the main air duct during use and improving the product recovery rate.

[0014] 1. By setting up a high-sealing mechanism, the sealing gasket moves under the combined action of the sealing spring and the telescopic column inside the sealing frame. This causes the telescopic column and the sealing spring to slide the sealing gasket inside the guide groove. Under the action of the guide groove, the sealing gasket is guided, so that the telescopic column and the sealing spring drive the sealing gasket to always move until it contacts the inner wall of the suction pump. Under the combined action of the sealing frame and the sealing gasket, the main air duct and the suction pump are sealed to prevent air leakage. This makes the overall airtightness of the exhaust gas collection device higher, achieving the high-sealing function of the exhaust gas collection device. As a result, the overall sealing performance of the exhaust gas collection device is higher during use, avoiding the phenomenon of exhaust gas leakage during the use of the exhaust gas collection device.

[0015] 2. With a convenient cleaning mechanism, the user removes the air inlet pipe from the surface of the main air duct and then pulls the first filter screen inside the main air duct upwards. This causes the first filter screen to slide along the fixing block inside the fixing groove. Under the combined action of the fixing block and the fixing groove, the first filter screen is guided, causing the fixing block to move the anti-detachment clip away from the inside of the air inlet pipe. At this time, the first filter screen moves the second magnet away from the surface of the first magnet, thereby pulling the first filter screen out from the inside of the main air duct for cleaning. This achieves the function of conveniently cleaning the first filter screen of the exhaust gas collection device, making it easy for the user to pull the first filter screen out from the inside of the main air duct for cleaning. This avoids the exhaust gas collection device becoming unusable due to clogging of the first filter screen during use.

[0016] 3. By incorporating a centralized collection mechanism, once the powder inside the collection box has been collected, the user pulls the collection box, causing the slider to slide inside the trough. The slider and trough work together to guide the collection box. Simultaneously, the collection box drives rotating balls to rotate on the surface of the trough. This coordinated action of the rotating balls and trough prevents the collection box from jamming during extraction, allowing it to be pulled out of the collection box for further processing of the powder. This achieves the centralized processing function of the waste gas collection device, ensuring that the powder is collected centrally, reducing clogging of the main duct during operation, and improving product recovery rate.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The structure of the waste gas collection device for feed processing provided by this utility model is as follows: Figure 1 and Figure 2As shown, the device includes a base 1, a mounting box 101 mounted on the top surface of the base 1, an air intake pump 114 (YX series, optional) installed inside the mounting box 101, the input end of the air intake pump 114 passing through the mounting box 101 and extending to the outside of the mounting box 101, a main air duct 102 above the mounting box 101, a control button 104 (LA series, optional) mounted on the surface of the main air duct 102, the input end of the air intake pump 114 electrically connected to the output end of the control button 104, a second filter screen 105 installed inside the main air duct 102, a mesh plate 107 installed inside the main air duct 102 below the second filter screen 105, an air inlet pipe 115 mounted above the main air duct 102 by screws, and a first filter screen 106 for filtering exhaust gas inside the main air duct 102. The top of the device base 1... A collection box 103 is installed on the surface of the location. Inside the collection box 103, a collection frame 113 for collecting dust is provided. A box body 110 is installed on the surface of the top of the collection box 103. Inside the box body 110, a pump body 112 is installed. The pump body 112 can be a YX series model. The input end of the pump body 112 is electrically connected to the output end of the control button 104. The output end of the pump body 112 passes through the collection box 103 and extends into the interior of the collection box 103. A fixing pipe 111 is installed on the input end of the pump body 112. A suction pipe 108 is installed on the surface of the fixing pipe 111 by screws. One end of the suction pipe 108 passes through the main air duct 102 and extends into the interior of the main air duct 102. The suction pipe 108 is located above the mesh plate 107. A valve 109 is fitted on the surface of the suction pipe 108. The valve 109 can be a TM series model. The input end of the valve 109 is electrically connected to the output end of the control button 104.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, both the inner walls of the main air duct 102 and the suction pump 114 are equipped with a high-sealing mechanism 2. The high-sealing mechanism 2 includes a sealing frame 21, a sealing gasket 22, a guide groove 23, a telescopic column 24, and a sealing spring 25. The inner wall of the main air duct 102 is equipped with a sealing frame 21, and a sealing gasket 22 is provided inside the sealing frame 21. One end of the sealing gasket 22 extends to the outside of the sealing frame 21 and contacts the inner wall of the suction pump 114. The inner wall of the sealing frame 21 is provided with a guide groove 23, which slides and engages with the surface of the sealing gasket 22. The inner wall of the sealing frame 21 is equipped with telescopic columns 24 at equal intervals, one end of which is fixed to the surface of the sealing gasket 22. The inner wall of the sealing frame 21 is equipped with sealing springs 25 at equal intervals, one end of which is fixed to the surface of the sealing gasket 22.

[0026] During implementation, the sealing spring 25 and the telescopic column 24 inside the sealing frame 21 work together to move the sealing gasket 22, causing the telescopic column 24 and the sealing spring 25 to slide the sealing gasket 22 inside the guide groove 23. The guide groove 23 guides the sealing gasket 22, ensuring that the telescopic column 24 and the sealing spring 25 keep moving the sealing gasket 22 until it contacts the inner wall of the suction pump 114. The sealing frame 21 and the sealing gasket 22 work together to seal the main air duct 102 and the suction pump 114, making the overall airtightness of the exhaust gas collection device higher, thus achieving the high sealing performance of the exhaust gas collection device.

[0027] Furthermore, such as Figure 2 and Figure 4 As shown, both the surface of the first filter 106 and the inner wall of the air inlet duct 115 are provided with a convenient cleaning mechanism 3. The convenient cleaning mechanism 3 contains a first magnet 31, a second magnet 32, and a convenient cleaning assembly 33. The convenient cleaning assembly 33 is disposed on the surface of the first filter 106 and the inner wall of the air inlet duct 115. The convenient cleaning assembly 33 consists of a fixing groove 331, a fixing block 332, and an anti-detachment clip 333. Fixing blocks 332 are installed on both sides of the surface of the first filter 106. The air inlet duct 115... The inner wall of each is provided with a fixing groove 331, and the surface of the fixing groove 331 and the fixing block 332 slide together. The inner wall of the air inlet pipe 115 is provided with a first magnet 31, and the surface of the bottom position of the first filter screen 106 is provided with a second magnet 32. The surface of the second magnet 32 ​​and the first magnet 31 magnetically attract each other. The surface of the fixing block 332 is provided with an anti-loosening clip 333 for preventing the first filter screen 106 from loosening. The anti-loosening clip 333 is engaged with the inner wall of the air inlet pipe 115.

[0028] In practice, the user removes the air inlet pipe 115 from the surface of the main air pipe 102, and then pulls the first filter screen 106 inside the main air pipe 102 upwards. This causes the first filter screen 106 to slide the fixing block 332 inside the fixing groove 331. Under the combined action of the fixing block 332 and the fixing groove 331, the first filter screen 106 is guided, causing the fixing block 332 to move the anti-detachment clip 333 away from the inside of the air inlet pipe 115. At this time, the first filter screen 106 moves the second magnet 32 ​​away from the surface of the first magnet 31, thereby pulling the first filter screen 106 out of the inside of the main air pipe 102 and cleaning the surface of the first filter screen 106, so as to realize the function of the exhaust gas collection device to facilitate the cleaning of the first filter screen 106.

[0029] Furthermore, such as Figure 2 and Figure 5As shown, a centralized collection mechanism 4 is provided on the surface of the collection frame 113 and the inner wall of the collection box 103. The centralized collection mechanism 4 includes a rotating ball 41, a groove 42 and a centralized collection component 43. The centralized collection component 43 is provided on the surface of the collection frame 113 and the inner wall of the collection box 103. The centralized collection component 43 is composed of a slider 431 and a groove 432. Slider 431 is installed on both sides of the collection frame 113. Grooves 432 are provided on the inner wall of the collection box 103. The surfaces of the grooves 432 and the sliders 431 slide against each other. Grooves 42 with equal spacing are provided on the surface of the bottom of the collection frame 113. Rotating balls 41 are provided on the surface of the grooves 42. The rotating balls 41 rotate against the inner wall of the grooves 42. The surface of the rotating balls 41 is in contact with the inner wall of the collection box 103.

[0030] During implementation, the user pulls the collection frame 113, causing the collection frame 113 to drive the slider 431 to slide inside the trough 432. Under the combined action of the slider 431 and the trough 432, the collection frame 113 is guided. At this time, the collection frame 113 drives the rotating ball 41 to rotate on the surface of the roller groove 42. With the cooperation of the rotating ball 41 and the roller groove 42, the collection frame 113 is prevented from getting stuck when it is pulled out, thereby pulling the collection frame 113 out from the inside of the collection box 103 and processing the powder inside the collection frame 113, so as to realize the function of centralized processing of collected powder by the exhaust gas collection device.

[0031] Working principle: In use, first place the device base 1 in the designated position. When the user places the main air duct 102 at the input end of the suction pump 114, the sealing spring 25 and the telescopic column 24 inside the sealing frame 21 work together to move the sealing gasket 22. This causes the telescopic column 24 and the sealing spring 25 to slide the sealing gasket 22 inside the guide groove 23. The guide groove 23 guides the sealing gasket 22, ensuring that the telescopic column 24 and the sealing spring 25 keep the sealing gasket 22 in contact with the inner wall of the suction pump 114. The sealing frame 21 and the sealing gasket 22 work together to seal the main air duct 102 and the suction pump 114, making the overall airtightness of the exhaust gas collection device higher. This achieves the high sealing performance of the exhaust gas collection device, thus improving its overall sealing performance during use and preventing exhaust gas leakage.

[0032] Subsequently, the exhaust gas inside the feed bin enters the main air duct 102 through the air inlet pipe 115. The exhaust gas is filtered by the first filter screen 106 and then filtered again by the second filter screen 105. The dust in the exhaust gas falls onto the surface of the mesh plate 107. The user then operates the control button 104, which controls the pump 112 and valve 109 inside the box 110. Under the action of the pump 112, the powder on the surface of the mesh plate 107 is sucked into the dust suction pipe 108 and then into the fixed pipe 111. Subsequently, the collected powder enters the collection frame 113 inside the collection box 103 through the pump 112. Under the action of the collection frame 113, the dust in the exhaust gas is collected.

[0033] Subsequently, when the first filter 106 is used for a long time, dust easily accumulates on its surface. It needs to be removed and cleaned promptly to prevent clogging. At this time, the user removes the air inlet duct 115 from the surface of the main air duct 102, and then pulls the first filter 106 inside the main air duct 102 upwards. This causes the first filter 106 to move the fixing block 332 within the fixing groove 331. Under the combined action of the fixing block 332 and the fixing groove 331, the first filter 106 is guided, causing the fixing block 332 to move the anti-detachment clip 333 away from the interior of the air inlet duct 115. At this point, the first filter... A filter screen 106 moves the second magnet 32 ​​away from the surface of the first magnet 31, thereby pulling the first filter screen 106 out of the main air duct 102 and cleaning its surface. This allows the exhaust gas collection device to easily clean the first filter screen 106, making it convenient for users to pull the first filter screen 106 out of the main air duct 102 and clean its surface. This avoids the exhaust gas collection device becoming unusable due to clogging of the first filter screen 106 during use.

[0034] Subsequently, after the powder inside the collection box 113 has been collected, the user pulls the collection box 113, causing the collection box 113 to drive the slider 431 to slide inside the trough 432. Under the combined action of the slider 431 and the trough 432, the collection box 113 is guided. At this time, the collection box 113 drives the rotating ball 41 to rotate on the surface of the roller groove 42. With the cooperation of the rotating ball 41 and the roller groove 42, the collection box 113 is prevented from getting stuck when it is pulled out, thereby pulling the collection box 113 out from the inside of the collection box 103 and processing the powder inside the collection box 113. This realizes the function of the exhaust gas collection device to centrally process the collected powder, so that the exhaust gas collection device can concentrate and collect the powder together when in use, reducing the phenomenon of blockage on the surface of the main air duct 102 during the use of the exhaust gas collection device, improving the product recovery rate, and finally completing the use of the exhaust gas collection device.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
