Description

Technical Field

[0001] This invention relates to the field of motor technology, and more specifically, to a waste gas treatment device for feed additive production. Background Technology

[0002] Feed flavoring and palatability enhancers, also known as flavoring agents or appetite enhancers, are additives specifically designed to improve feed palatability and increase the appetite of livestock. Waste gas treatment is a crucial environmental aspect of the feed flavoring and palatability enhancer production process. These waste gases may contain harmful components such as volatile organic compounds (VOCs), ammonia, and hydrogen sulfide. If these gases are released directly into the atmosphere without proper treatment, they can harm the environment and human health. Chinese patent announcement number CN117414650A discloses a waste gas treatment device for feed additive production, including a filter mechanism. An air inlet is tightly connected to one side of the filter mechanism's inner wall, and a vent pipe is tightly connected to the top inner wall of the filter mechanism. A first suction pump is installed in the middle section of the vent pipe, and one end of the vent pipe is connected to a first three-way vent pipe. A bidirectional solenoid valve is installed on the first three-way vent pipe, and two deodorization mechanisms are tightly connected to their two output ends. A second three-way vent pipe is tightly connected to the same side of the inner wall of both deodorization mechanisms, and solenoid valves are installed at the connection points between the two deodorization mechanisms and the second three-way vent pipe. A second suction pump is tightly connected to the output end of the second three-way vent pipe. This waste gas treatment device for feed additive production disclosed in this patent achieves continuous waste gas treatment while preventing waste gas leakage and ensuring thorough deodorization. Although the above patent utilizes two deodorization mechanisms and components such as the second and third vent pipes to achieve continuous treatment of exhaust gas, avoids exhaust gas leakage and ensures the thoroughness of exhaust gas deodorization, it is necessary to ensure that the air circulation of exhaust gas is sealed during the deodorization and dust removal process, and the treatment on different equipment requires a large amount of factory space. In view of this, we propose a waste gas treatment device for feed additive production. Summary of the Invention

[0009] As a preferred embodiment of the present invention, the extrusion device includes a sliding frame, which is slidably connected to the top of a fixed frame. A fixed plate is fixedly connected to the top of the sliding frame, and connecting plates are fixedly connected to both sides of the fixed plate.

Connecting plates 4511 are fixedly connected to both sides of the fixed plate 451.

A protruding strip 453 is fixedly connected to the outer wall of the sliding frame 45. Fasteners 4531 are provided on both sides of the protruding strip 453.

[0022] like Figures 7-8As shown, a fixed column 454 is fixedly connected to the end of the sliding frame 45 away from the fixed block 452. A slide rail 455 is fixedly connected to the inner wall of the sliding frame 45 near the fixed column 454. A vent column 46 is slidably connected to the slide rail 455. Multiple vent holes 461 are opened on the outer wall of the vent column 46, which are connected to the connecting pipe 31. A push-pull block 434 is rotatably connected to the end of the third connecting rod 433 away from the rotating rod 42. A toggle rod 4341 is fixedly connected to the top of the push-pull block 434. The toggle rod 4341 is slidably connected to the outer wall of the protruding strip 453, and the buckle 4531 and the toggle rod 4341 are on the same horizontal line. The push-pull block 434 is slidably connected to the inner side of the sliding frame 45. One end of the connecting rod 433 is provided with a compression assembly 47, which includes a first compression column 471 and a second compression column 472. The first compression column 471 is fixedly connected to the end of the push-pull block 434 away from the third connecting rod 433. The second compression column 472 is hollow inside. An air intake pipe 4721 is fixedly connected to the end of the second compression column 472 away from the first compression column 471. The second compression column 472 is slidably connected to the outer wall of the fixed column 454. A first connecting column 44 is fixedly connected to the outside of the toggle rod 4341. The first connecting column 44 is fixedly connected to the first filter plate 21 at the end away from the toggle rod 4341. The outer diameter of the first compression column 471 and the second compression column 472 matches the inner diameter of the air column 46.

[0023] Therefore, when exhaust gas needs to be treated, such as Figures 2-7 As shown, the staff connects the exhaust gas source equipment to the air inlet 11. At this time, the exhaust gas enters the first chamber 5 of the treatment chamber 1 from the air inlet 11. In the first chamber 5, part of the exhaust gas passes through the first filter plate 21 to block dust, and another part of the exhaust gas also passes through the second filter plate 22 to block dust. Then, the exhaust gas flows through the first filter plate 21 and the second filter plate 22 to the gap between the drawer 15 and the dust collection plate 23 into the second chamber 51. The exhaust gas in the second chamber 51 flows into the ventilation column 46 from the ventilation hole 461 or the air inlet pipe 4721 and flows into the third chamber 52 through the connecting pipe 31. The mist of chemical solution is sprayed out through the spray pipe 121 and mixes with the dust-removed exhaust gas in the third chamber 52 for deodorization. The function of the mist of chemical solution is partly to mix with the exhaust gas for deodorization. Similarly, after the chemical solution mixes with the exhaust gas in the air, it can effectively reduce a large part of the dust in the exhaust gas. Furthermore, the required dosage of chemical solution varies depending on the volume of exhaust gas entering the system. When the volume of exhaust gas entering the system becomes unbalanced with the volume of chemical solution being sprayed, the extrusion device 4 is activated. Driven by the motor 41, the rotating rod 42 rotates. During the rotation of the rotating rod 42, the first connecting rod 431 rotates as well. Figure 6As shown, during the rotation of the first connecting rod 431, it pulls the second connecting rod 432 and the sliding frame 45 to slide to the right. Correspondingly, the push-pull block 434 and the actuating rod 4341 slide to the right within the sliding frame 45. Simultaneously, the push-pull block 434 drives the first extrusion column 471 to slide to the right within the sliding frame 45. Meanwhile, the sliding frame 45 itself slides to the right on the fixed frame 411. Similarly, driven by the fixed column 454, the second extrusion column 472 slides to the right. At this time, the first extrusion column 471 and the second extrusion column 472 gradually move away from each other. Conversely, when the rotating rod 42 drives the first connecting rod 431 to rotate to the other side, the first extrusion column 471 and the second extrusion column 472 will gradually approach each other. When the first extrusion column 471 and the second extrusion column 472 gradually move away from each other, they will no longer block the vent 461, allowing the exhaust gas to flow from the vent 461 into the connecting pipe 31 and into the third chamber 52. Under the continuous rotation of the rotating rod 42, the first extrusion column 471 and the second extrusion column 472 form a mutual extrusion, intermittently delivering exhaust gas into the third chamber 52, thereby reducing the amount of exhaust gas delivered. Similarly, such as Figure 6 As shown, when the sliding frame 45 drives the second extrusion column 472 to slide to the rightmost end, the air intake pipe 4721 will be attached to the pad plate 14 and the air intake pipe 4721 will be fixed to the pad plate 14 by the buckle, so that the air intake pipe 4721 is sealed. When the toggle rod 4341 slides to the left side of the buckle 4531 on the protrusion strip 453, it will always slide at the left side of the buckle 4531 on the protrusion strip 453 due to the obstruction of the buckle 4531. At this time, the exhaust gas can only flow in from the vent hole 461. Under the continuous rotation of the first connecting rod 431, only the first extrusion column 471 is driven to slide, while the second extrusion column 472 will continuously squeeze and transport the exhaust gas in the vent column 46. It should be noted that the first connecting rod 431 is an electrically retractable connecting rod. When the actuating rod 4341 is blocked by the latch 4531, it retracts under electric drive. At this time, the sliding distance of the sliding frame 45 to the right also becomes smaller. Similarly, the latch 4531 is also an electrically retractable component. By adjusting different modes in the control room, it can automatically retract and unfold under electric drive.
