Description

Technical Field

[0001] This utility model relates to the field of material feeding trough technology, specifically to a material feeding trough device that prevents clogging and material sticking. Background Technology

[0002] In the production processes of industries such as chemicals, food, building materials, and pharmaceuticals, the feed chute is a key component of the material conveying system.

[0003] Existing feeding troughs mostly adopt an inclined design to achieve material flow by gravity. However, for materials with high viscosity or that are prone to moisture absorption and clumping, gravity alone is not enough to effectively prevent material from sticking. Long-term accumulation will lead to narrowing of the feeding channel, affecting conveying efficiency, or even complete blockage. At the same time, materials are prone to clumping at the discharge port due to accumulation pressure or humidity, which is especially common for materials with poor flowability. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a feeding trough device that prevents clogging and material adhesion. By setting the anti-clogging component, the area of ​​the discharge port changes dynamically, which generates a squeezing and shearing effect on the agglomerated material, enhances the crushing ability, and avoids material bridging. By setting the anti-wall adhesion component, the material is kept dry and the material flowability is improved. In conjunction with the wall-adhering airflow layer blown out by the flat nozzle, the material is continuously peeled off and adhered.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material feeding trough device for preventing clogging and material sticking, comprising:

[0006] The material feeding trough body has a feeding hopper connected to the top and a discharge trough connected to the bottom. A discharge trough is provided inside the material feeding trough body.

[0007] An anti-blocking component is provided between the discharge trough and the feed trough body to prevent the discharge trough from becoming blocked. The anti-blocking component includes: an equipment box, a geared motor, a drive rod, a cam, and a movable plate. Two equipment boxes are installed on the back of the feed trough body. A geared motor is installed inside the equipment box. A drive rod is driven and connected to one side of the geared motor. Multiple cams are connected to the drive rod. A movable plate is provided on one side of the cam.

[0008] An anti-fouling component is provided inside the material feeding trough body to reduce material fouling. The anti-fouling component includes a heating chamber, a heater, an equipment chamber, and an air pump. Two heating chambers are provided inside the material feeding trough body, and heaters are installed inside the heating chambers. An equipment chamber is provided inside the material feeding trough body, and an air pump is installed inside the equipment chamber.

[0009] Furthermore, the material feeding trough body has two movable cavities that communicate with the discharge trough. The movable cavities are symmetrically arranged. One end of the drive rod extends into the movable cavity and is connected to the inner wall of the movable cavity through a bearing. The top of the movable plate is rotatably connected to the movable cavity.

[0010] Furthermore, the cam protrusions on the two drive rods are not aligned, and the cam surfaces are in close contact with one side of the movable plate.

[0011] Furthermore, the discharge trough is inclined toward the outlet trough, and a heating plate is installed on the inclined surface of the discharge trough, the heating plate being electrically connected to the heater.

[0012] Furthermore, the air inlet of the vacuum pump protrudes from the outer surface of the material discharge trough body, the material discharge trough body is provided with a conduit, one end of the conduit is connected to the air outlet of the vacuum pump, and the other end of the conduit extends to the top of the inclined surface of the discharge trough and is connected to a flat nozzle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By setting up the anti-blocking component, the asymmetric cam drives the movable plate to swing back and forth, causing the area of ​​the discharge port to change dynamically. This generates a squeezing and shearing effect on the agglomerated material, enhancing the crushing capacity and preventing material bridging. Secondly, by setting up the anti-wall-hanging component, the material is kept dry and its flowability is improved. Combined with the wall-adhering airflow layer blown out by the flat nozzle, it continuously peels off the adhering material, reducing the tendency of sticky material to adhere to the inclined surface.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This application provides a non-clogging and non-sticking material feeding trough device, which solves the problem of existing material feeding troughs being prone to sticking to the walls and clogging.

[0025] By setting up the anti-blocking component, the asymmetric cam 203 drives the movable plate 204 to swing back and forth, causing the area of ​​the discharge port to change dynamically. This generates a squeezing and shearing effect on the agglomerated material, enhancing the crushing capacity and preventing material bridging. Secondly, by setting up the anti-wall-hanging component, the material is kept dry and its flowability is improved. Combined with the wall-adhering airflow layer blown out by the flat nozzle 403, the material adheres continuously and peels off the sticky material, reducing the tendency of sticky material to adhere to the inclined surface.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1 , Figure 2As shown, a non-clogging and non-sticking feeding trough device includes: a feeding trough body 1, with a feeding hopper 101 connected to the top of the feeding trough body 1 and a discharging trough 102 connected to the bottom of the feeding trough body 1, and a discharge trough inside the feeding trough body 1; and an anti-clogging component, which is located between the discharging trough 102 and the feeding trough body 1 to prevent the discharging trough 102 from clogging. The anti-clogging component includes: an equipment box 2, a geared motor 201, a drive rod 202, a cam 203, and a movable plate 204. Two equipment boxes 2 are installed on the back of the feeding trough body 1, and the geared motor is installed inside the equipment box 2. 201, a drive rod 202 is connected to one side of the geared motor 201, and multiple cams 203 are connected to the drive rod 202. A movable plate 204 is provided on one side of the cam 203. The anti-sticking component is located inside the feeding trough body 1 to reduce the situation of material sticking. The anti-sticking component includes: a heating chamber 3, a heater 301, an equipment chamber 4, and an air pump 401. Two heating chambers 3 are opened inside the feeding trough body 1. The heater 301 is installed inside the heating chamber 3. The equipment chamber 4 is opened inside the feeding trough body 1. The air pump 401 is installed inside the equipment chamber 4.

[0028] In use, the material is poured into the discharge trough body 1 through the feed hopper 101, and then discharged into the discharge trough 102 through the discharge channel inside the discharge trough body 1. The heater 301 in the anti-sticking component heats the inclined surface of the discharge trough, so that the material is heated after falling onto the inclined surface of the discharge trough, keeping the material dry and fluid, and reducing the adhesion of some viscous materials. At the same time, the air pump 401 in the anti-sticking component blows air onto the inclined surface of the discharge trough, so that an airflow layer is formed on the surface of the inclined surface of the discharge trough. Combined with the heating of the heater 301, the material is cleaned of the material adhering to the wall. When the material falls into the discharge trough 102, the cam 203 in the anti-blocking component rotates, which drives the movable plates 204 on both sides to swing back and forth. The inclination of the movable plates 204 on both sides is different, so that the area of ​​the discharge area of ​​the discharge trough changes dynamically, and the blocked material is squeezed to reduce the blockage.

[0029] Combination Figure 4 and Figure 7 As shown, further, the material feeding trough body 1 has two movable cavities 103 that communicate with the discharge trough. The movable cavities 103 are symmetrically arranged. One end of the drive rod 202 extends into the movable cavity 103 and is connected to the inner wall of the movable cavity 103 through a bearing. The top of the movable plate 204 is rotatably connected to the movable cavity 103. The cams 203 on the two drive rods 202 have different directions of protrusion, and the surface of the cams 203 is in close contact with one side of the movable plate 204. Multiple cams 203 are evenly distributed on the drive rods 202.

[0030] In use, the geared motor 201 drives the drive rod 202 to rotate, which in turn drives multiple cams 203 to rotate. This causes the protruding parts of the multiple cams 203 on the same rod to turn towards the movable plate 204, pushing the movable plate 204 to swing towards the discharge area of ​​the discharge chute. When the protruding parts rotate away from the movable plate 204, the movable plate 204, under the action of gravity, adheres tightly to the surface of the cams 203 and swings towards the movable cavity 103. This process repeats, allowing the movable plate 204 to continuously swing back and forth towards the discharge area of ​​the discharge chute. The two drive rods... The asymmetrical arrangement of the cam 203 on the moving rod 202 causes the swing amplitude of the two movable plates 204 at the same time to be different, resulting in a dynamic change in the distance between the two movable plates 204. When both movable plates 204 swing towards the discharge chute, they can squeeze the clumped material, dispersing it and preventing blockage. The bottoms of both movable plates 204 extend into the discharge chute 102, and the maximum distance between the bottoms of the two movable plates 204 is less than the size of the discharge chute 102, which can effectively prevent the discharge chute 102 from being blocked.

[0031] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The discharge trough is inclined towards the discharge trough 102, and a heating plate 302 is installed on the inclined surface of the discharge trough. The heating plate 302 is electrically connected to the heater 301. The air inlet of the vacuum pump 401 protrudes from the outer surface of the discharge trough body 1. The discharge trough body 1 is provided with a conduit 402, and one end of the conduit 402 is connected to the air outlet of the vacuum pump 401. The other end of the conduit 402 extends to the top of the inclined surface of the discharge trough and is connected to a flat nozzle 403. The surface of the heating plate 302 is smooth to reduce material adhesion. A filter screen is provided at the air inlet of the vacuum pump 401 to prevent dust from entering.

[0032] During use, the heater 301 powers the heating tubes inside the heating plate 302, generating heat that is transferred to the heating plate 302. This heats the material passing over the heating plate 302, ensuring its dryness and preventing easily hygroscopic and clumping materials from adhering to the inclined surface of the discharge trough. Simultaneously, the air pump 401 draws in external air and delivers it through the conduit 402 to the flat nozzle 403. The air is then blown onto the inclined surface of the discharge trough through the flat nozzle 403, creating an airflow layer that, in conjunction with the heating of the heater 301, removes the material adhering to the wall.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
