Description

Technical Field

[0001] This utility model relates to the field of pneumatic gate technology for additive premixed feed production lines, specifically a pneumatic gate device for additive premixed feed production lines. Background Technology

[0002] The additive premixed feed production line is a specialized equipment system for mixing trace components such as vitamins, minerals, and amino acids with carriers or diluents in a specific ratio to produce uniform intermediate feed products. Its core processes include automatic batching, efficient mixing, and precise packaging: the automatic batching system achieves multi-stage precise weighing through electronic scales, ensuring that the error of trace components is less than 0.02%; the mixing stage adopts a twin-shaft paddle or drum-type stainless steel mixer, with a mixing uniformity variation coefficient ≤5% and a residue <100g / t; the packaging system supports automatic metering of 5-50kg specifications, is equipped with a pulse dust collector to reduce dust pollution, and has a compact overall layout, equipped with positive pressure pneumatic conveying and a sealed design to effectively reduce the risk of cross-contamination.

[0003] In existing technologies, due to the complex composition of feed additives and mixed feeds, which contain dust, particles, etc., these substances are easily stuck in the sealing parts during frequent valve opening and closing, damaging the sealing structure. Moreover, after long-term use, the sealing parts wear and age, resulting in a decline in sealing performance. In addition, if the installation accuracy of the pneumatic valve device does not meet the standards, it will also cause poor sealing. These problems lead to material leakage, which not only wastes raw materials and increases costs, but may also pollute the production environment, affect product quality, and bring many adverse effects to the enterprise's production. Therefore, we need a pneumatic gate device for an additive premixed feed production line. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic gate device for an additive premixed feed production line, in order to solve the problems of poor sealing effect and easy material leakage in existing material conveying pipeline sealing devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic gate device for an additive premixed feed production line, comprising a hopper, a screw conveyor at the bottom of the hopper, a sealing assembly at one end of the screw conveyor, a quick-release assembly movably connected to the bottom of the sealing assembly, a mixer fixedly connected to the bottom of the quick-release assembly, the sealing assembly comprising a valve body fixedly mounted on the top of the mixer, a cylinder fixedly connected to one end of the valve body, a valve plate fixedly connected to one end of the cylinder, a sealing block fixedly connected to one side of the valve plate, a sealing gasket fixedly connected to one side of the valve plate, a positioning hole provided inside the sealing gasket, a connecting rod slidably connected inside the positioning hole, a groove provided inside the valve body, and a sealing groove provided inside the valve body.

[0006] Preferably, the valve plate forms a sealing structure through a sealing block and a sealing groove, and the outer diameter of the sealing block matches the inner diameter of the sealing groove, and the outer wall of the sealing block fits against the inner wall of the sealing groove.

[0008] Preferably, the quick-release assembly includes a bolt, which is fixed to one side of the valve body. A nut is threaded to the bottom of the bolt. A fixing block is provided on one side of the valve body. A connecting block is fixedly connected to the bottom of the fixing block. A spring is sleeved on the outer wall of the connecting block. A locking block is engaged with one end of the connecting block. A movable rod is fixedly connected to one end of the locking block. A handle is fixedly connected to one end of the movable rod. A feed hopper is rotatably connected to the outer wall of the handle.

[0009] Preferably, the connecting block forms an elastic structure with the fixing block and the spring, and the top of the connecting block is fixedly connected to the bottom of the fixing block, and the spring is sleeved on the outer wall of the connecting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: 1. In order to solve the problem of poor sealing effect and easy material leakage in the sealing device of the material conveying pipeline in the prior art, this application sets up a sealing component and uses a cylinder to push the valve plate so that the sealing block fits into the sealing groove in the valve body to achieve initial sealing. At the same time, the valve plate drives the sealing gasket to slide along the connecting rod to form a double seal, which effectively prevents material leakage. When it is necessary to open the gate, the cylinder drives the valve plate to move in the opposite direction, the sealing block disengages from the sealing groove, and the material passes through smoothly. The operation is simple and improves the stability and safety of material conveying. 2. To address the cumbersome connection process between the valve body and the feed hopper in existing technologies, which makes it difficult to simultaneously ensure both convenient and secure installation, this application proposes a connection assembly that includes bolts, nuts, and a locking mechanism. First, the valve body and the feed hopper are aligned. Pulling the handle causes the movable rod to rotate the locking block, pressing the connecting block downwards and locking it at the corner, achieving initial locking. During this process, the spring is compressed, enhancing connection stability. Subsequently, bolts are used to penetrate the bottom of the valve body and the top of the feed hopper, and nuts are tightened for secondary fixation. This design simplifies the installation process and significantly enhances connection strength through a dual-fixing method, effectively preventing leakage during material conveying.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model embodiment provides a pneumatic gate device for an additive premixed feed production line, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the assembly includes a hopper 1, a screw conveyor 2 at the bottom of the hopper 1, a sealing assembly 3 at one end of the screw conveyor 2, a quick-release assembly 4 movably connected to the bottom of the sealing assembly 3, and a mixer 5 fixedly connected to the bottom of the quick-release assembly 4. The sealing assembly 3 includes a valve body 301, which is fixedly attached to the top of the mixer 5. A cylinder 302 is fixedly connected to one end of the valve body 301, and a valve plate 303 is fixedly connected to one end of the cylinder 302. A sealing block 304 is fixedly connected to one side of the valve plate 303, and a sealing gasket 305 is fixedly connected to one side of the valve plate 303. A positioning hole 306 is provided inside the sealing gasket 305, and a connecting rod 307 is slidably connected inside the positioning hole 306. A groove is provided inside the valve body 301. 308. A sealing groove 309 is provided inside the valve body 301. The hopper 1 is used to store materials. The bottom screw conveyor 2 transports the materials to the sealing assembly 3. When the cylinder 302 is activated, it can push the valve plate 303 to move, which in turn moves the sealing block 304. This allows the sealing block 304 to fit into the sealing groove 309 inside the valve body 301 to achieve a preliminary seal. The valve plate 303 can also move the sealing gasket 305, which slides along the connecting rod 307 through the positioning hole 306. This double seal prevents material leakage. When the gate needs to be opened, the cylinder 302 moves the valve plate 303, and the sealing block 304 disengages from the sealing groove 309, allowing the material to pass through.

[0017] Furthermore, such as Figure 4 and Figure 5 As shown, the valve plate 303 forms a sealing structure with the sealing block 304 and the sealing groove 309. The outer diameter of the sealing block 304 matches the inner diameter of the sealing groove 309, and the outer wall of the sealing block 304 fits against the inner wall of the sealing groove 309. Through the sealing block 304, the valve plate 303 can fit against the sealing groove 309, thereby sealing the valve plate 303 with the valve body 301 and preventing material leakage.

[0018] Furthermore, such as Figure 4 and Figure 5 As shown, the sealing gasket 305 forms a sliding structure with the connecting rod 307 through the positioning hole 306, and the outer diameter of the connecting rod 307 matches the inner diameter of the positioning hole 306. The outer wall of the connecting rod 307 is fitted to the inner wall of the positioning hole 306. Through the positioning hole 306, the positioning hole 306 can slide along the outer wall of the connecting rod 307 under the action of the sealing gasket 305.

[0019] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 5As shown, the quick-release assembly 4 includes a bolt 401, which is fixed to one side of the valve body 301. A nut 402 is threaded onto the bottom of the bolt 401. A fixing block 403 is provided on one side of the valve body 301. A connecting block 404 is fixedly connected to the bottom of the fixing block 403. A spring 405 is sleeved on the outer wall of the connecting block 404. A locking block 406 is engaged with one end of the connecting block 404. A movable rod 407 is fixedly connected to one end of the locking block 406. A handle 408 is fixedly connected to one end of the movable rod 407. When the valve body 301 is aligned with the feed hopper 409 and the handle 408 is pulled, the handle 408 can drive the movable rod 407 to rotate, which in turn drives the locking block. Rotating 406 allows the locking block 406 to press against one end of the connecting block 404, causing the connecting block 404 to move downwards. This allows one end of the locking block 406 to engage at the bend of the connecting block 404, completing the initial engagement between the valve body 301 and the feed hopper 409. During engagement, the connecting block 404 drives the fixing block 403 to move, which in turn causes the fixing block 403 to press against the spring 405. The spring 405 is then compressed under the support of the feed hopper 409, improving connection stability. At this point, the valve body 301 and the feed hopper 409 can be separated. A bolt 401 is then inserted through the bottom of the valve body 301 and the top of the feed hopper 409, and a nut 402 is tightened for secondary fixation.

[0020] Furthermore, such as Figure 5 As shown, the connecting block 404 forms an elastic structure with the fixing block 403 and the spring 405. The top of the connecting block 404 is fixedly connected to the bottom of the fixing block 403, and the spring 405 is sleeved on the outer wall of the connecting block 404. With the spring 405, the fixing block 403 can compress the spring 405 under the drive of the connecting block 404, and the spring 405 can be compressed under the support of the valve body 301.

[0021] Furthermore, such as Figure 5 As shown, the movable rod 407 forms a locking structure with the connecting block 404 via the locking block 406. One end of the locking block 406 is fixedly connected to one side of the movable rod 407, and the other end of the locking block 406 is locked to one end of the connecting block 404. With the locking block 406, the locking block 406 can rotate under the drive of the movable rod 407, which can squeeze one end of the connecting block 404, so that the connecting block 404 is locked at the corner of the connecting block 404, thus achieving initial fixation.

[0022] Furthermore, such as Figure 1 and Figure 2As shown, the valve body 301 is fixed to the top of the feed hopper 409 by bolts 401, and one end of the bolts 401 passes through the top of the valve body 301 and the feed hopper 409 and is connected to the nut 402. The bolts 401 can fix the top of the valve body 301 and the feed hopper 409, thus achieving secondary fixation.

[0023] Working principle: The hopper 1 is used to store materials. The bottom screw conveyor 2 transports the materials to the sealing assembly 3. Activating the cylinder 302 moves the valve plate 303, which in turn moves the sealing block 304. This allows the sealing block 304 to engage with the sealing groove 309 in the valve body 301, achieving a preliminary seal. The valve plate 303 then moves the sealing gasket 305, which slides along the connecting rod 307 through the positioning hole 306. This double seal prevents material leakage. When the valve needs to be opened, the cylinder 302 moves the valve plate 303, disengaging the sealing block 304 from the sealing groove 309, allowing material to pass through. Aligning the valve body 301 with the feed hopper 409 and pulling the handle 408 allows the handle 401 to open. 8. Rotating the movable rod 407 causes the locking block 406 to rotate, which in turn causes the locking block 406 to press against one end of the connecting block 404, causing the connecting block 404 to move downwards. This allows one end of the locking block 406 to engage at the bend of the connecting block 404, completing the initial engagement between the valve body 301 and the feed hopper 409. During the engagement process, the connecting block 404 drives the fixed block 403 to move, which in turn causes the fixed block 403 to press against the spring 405. This allows the spring 405 to be compressed under the support of the feed hopper 409, improving connection stability. At this point, the valve body 301 and the feed hopper 409 can be separated. A bolt 401 is then inserted through the bottom of the valve body 301 and the top of the feed hopper 409, and a nut 402 is tightened for secondary fixation.

[0024] 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. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
