Abstract
Description
Technical Field
[0001] This utility model relates to the field of hopper technology, specifically to an anti-clogging hopper. Background Technology
[0002] In industrial production, hoppers, as key components of material conveying systems, are widely used in food processing, chemical, metallurgical, and building materials industries. Traditional hopper structures typically employ a vertical discharge design, which leads to clogging problems during actual use. When materials have high moisture content, uneven particle size, or poor flowability, bridging can easily occur at the connection between the hopper and the conveying pipeline. This is especially true at bends in the connecting pipes, where material accumulation causes blockages, severely impacting production continuity. Therefore, an anti-clogging hopper has been proposed to address these issues. Utility Model Content

Therefore, an anti-blocking hopper is proposed.

[0021] 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.
[0022] In the embodiments, by Figure 1-3 Provided is an anti-clogging hopper, including a support 1, a hopper 2 fixedly connected to the top of the support 1, the hopper 2 being funnel-shaped, a connecting pipe 3 connected to the bottom of the hopper 2, a switch mechanism 4 for controlling the amount of material discharged is provided on the outside of the connecting pipe 3, a discharge pipe 5 connected to the bottom of the connecting pipe 3, the discharge pipe 5 being inclined, and an anti-clogging mechanism 6 provided at the bottom of the connecting pipe 3.
[0023] With the above setup, materials (such as powders, granules, and small lumps) are fed into the hopper 2 through its open top. Because the hopper 2 is funnel-shaped, the materials naturally converge towards the bottom center under gravity. The converged materials enter the connecting pipe 3 from the conical bottom of the hopper 2, and then enter the discharge pipe 5 from the bottom of the connecting pipe 3. Since the discharge pipe 5 is inclined (generally with an inclination angle of 30°-60°), the materials slide downwards along the inclined surface under gravity, reducing frictional resistance and accumulation with the pipe wall. Finally, the materials are discharged from the end of the discharge pipe 5, completing the entire feeding process. If blockage occurs during the process, an anti-blockage mechanism 6 can be used to clear the blockage. The anti-blockage mechanism 6 acts directly on the bottom of the connecting pipe 3 (a point prone to blockage). Compared to existing technologies, this reduces the blockage rate, minimizes downtime for maintenance, and does not affect the continuity of normal production.
[0024] Reference Figure 1-3 The switching mechanism 4 includes a partition 41. The partition 41 is fixedly connected to the outside of the connecting pipe 3. The switch plate 42 is slidably connected to the inside of the partition 41. The switch plate 42 divides the connecting pipe 3 into two sections. A through hole 43 is opened on the switch plate 42. The inner diameter of the through hole 43 is the same as the inner diameter of the connecting pipe 3. A handle 44 is fixedly connected to the front end of the switch plate 42.
[0025] With the above structural setup, pushing the handle 44 aligns the through hole 43 of the switch plate 42 with the axis of the connecting pipe 3, forming a continuous channel through the through hole 43, allowing material to pass through without resistance (maximum flow rate). At this time, the inner wall of the through hole 43 is flush with the inner wall of the connecting pipe 3, without steps or necking, avoiding material buildup or turbulence. Closed or adjustable state: Sliding the switch plate 42 laterally misaligns the through hole 43 with the connecting pipe 3, the degree of misalignment controlling the flow cross-sectional area; Fully closed: The through hole 43 is completely deviated, and the switch plate 42 physically blocks the pipe (cutting off material flow); Half-open: The through hole 43 partially covers the connecting pipe 3, reducing the cross-sectional area → the flow rate decreases proportionally.
[0026] Reference Figure 1-3 The anti-blocking mechanism 6 includes a guide tube 61, the bottom end of the connecting tube 3 is connected to the guide tube 61, the inner diameter of the guide tube 61 is smaller than the inner diameter of the connecting tube 3, the bottom end of the guide tube 61 is provided with an electric telescopic rod 62, the telescopic end of the electric telescopic rod 62 is slidably connected to the inner side of the guide tube 61, the telescopic end of the electric telescopic rod 62 is adapted to the inner diameter of the guide tube 61, and the telescopic end of the electric telescopic rod 62 is fixedly connected to a top head 63.
[0027] With the above-mentioned structure, when material blockage occurs, the electric telescopic rod 62 is activated, and the telescopic rod pushes the top head 63 to move up and down reciprocally. The top head 63 is lifted upward to shear the agglomerated material (such as clumps of fiber or wet powder) and force it to break up. After the blockage is cleared, the electric telescopic rod 62 resumes normal feeding.
[0028] Reference Figure 1-3The left end of the connecting pipe 3 is open.
[0029] With the above structural design, when the viscosity coefficient of the material is too high and it sticks to the top head 63, the top head 63 can be cleaned with water sprayed by a cleaning water gun after the feeding process is finished, so as to avoid affecting normal operation.
[0030] Reference Figure 1-3 Among them, the top 63 is conical;
[0031] With the above structural design, the cone tip penetrates the blockage with a point load, making it easier to puncture the blockage compared to a flat head.
[0032] Reference Figure 1-3 Among them, four reinforcing rods 7 are fixedly connected to the bracket 1, and the four reinforcing rods 7 are respectively fixedly connected to the outside of the fixed end of the electric telescopic rod 62;
[0033] With the above structural arrangement, the four reinforcing rods 7 are evenly distributed in a 90° circumferential direction to form a spatial truss system, which increases the structural stability.
