Description

Technical Field

[0001] This utility model relates to the field of auxiliary material silo technology, and in particular to an anti-clogging conditioner dispensing auxiliary material silo. Background Technology

[0002] Conditioning agents (such as polyaluminum chloride, polyacrylamide, lime, or fly ash) are used in sludge treatment to improve the dewatering performance of sludge. They work by neutralizing charge, bridging by adsorption, or altering particle structure, causing fine colloidal particles to aggregate into larger flocs, thereby improving the efficiency of subsequent mechanical dewatering and reducing the moisture content of the sludge cake. Since conditioning agents are mostly ultrafine powders or materials that are prone to absorbing moisture and caking, they are easily blocked at the silo outlet during storage and feeding due to moisture absorption, electrostatic adsorption, or compaction. This can lead to uneven dosage or even interruption, directly affecting the sludge conditioning effect and the stability of the dewatering system. Therefore, anti-clogging design must be adopted to ensure continuous, accurate, and stable feeding.

[0003] In existing technologies, conditioner feeding silos commonly employ auxiliary arch-breaking devices such as vibratory motors or air cannons. Vibratory motors use high-frequency vibrations to loosen and flow the material, while air cannons utilize the shock waves generated by the instantaneous release of compressed air to break up the material's arch structure. Some systems also supplement this with passive maintenance methods such as manual tapping or periodic silo cleaning in an attempt to maintain smooth material flow.

[0004] However, these methods have obvious limitations. For conditioners with high moisture content and strong viscosity (such as PAM and lime), vibration energy is difficult to effectively transfer to the interior of the material, resulting in a weak arch-breaking effect. At the same time, continuous vibration can easily lead to cracking of the silo welds and loosening of the support structure, posing safety hazards. Although air cannons have strong impact force, their action time is extremely short and their direction is fixed, which can only disturb the surface material and is almost ineffective against deep compacted agglomerates. Moreover, frequent use results in high energy consumption and noise, making them unsuitable for continuous operation. Therefore, we propose an anti-clogging conditioner feeding silo to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-clogging conditioner feeding hopper.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A hopper for discharging auxiliary materials of an anti-clogging conditioner includes a hopper, a material frame fixedly connected to the bottom of the hopper, a breaking ring slidably connected to the bottom of the inner wall of the hopper, two fixed plates fixedly connected to the top of the breaking ring, a guide rod fixedly connected to the outer wall of one of the fixed plates, two breaking V-shaped plates fixedly connected to the inner wall of the breaking ring, a frame fixedly connected to the outer wall of the hopper, a hydraulic cylinder fixedly connected to the top of the frame, the outer wall of the output end of the hydraulic cylinder fixedly connected to the outer wall of the other fixed plate, and a discharging assembly provided at the bottom of the hopper.

[0010] Preferably, the outer wall of the feeding hopper is provided with a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the output end of the hydraulic cylinder.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Depend on Figures 1-4 As shown, a hopper for discharging auxiliary materials for anti-clogging conditioner is disclosed, comprising a hopper 1. Multiple annular ribs 2 are fixedly connected to the outer wall of the hopper 1. The annular ribs 2 increase the stress support points of the outer wall of the hopper 1, greatly improving its resistance to deformation and fatigue, and preventing the hopper body from cracking due to material breakage vibration or heavy material pressure. A top ring 3 is fixedly connected to the top of the hopper 1. An existing hopper cover can be placed on the top of the top ring 3 to reduce the intrusion of external moisture.

[0018] A material frame 4 is fixedly connected to the bottom of the feeding hopper 1, and two mounting seats 5 are fixedly connected to the outer wall of the feeding hopper 1. The mounting seats 5 increase the contact area between the feeding hopper 1 and the mounting surface, distribute the weight of the hopper and the internal materials, and ensure that the hopper is stably installed without loosening or shifting.

[0019] The bottom of the inner wall of the feeding hopper 1 is slidably connected to a crushing ring 6. The crushing ring 6 can slide left and right under the drive of the hydraulic cylinder 11, which drives the crushing V-shaped plate 10 to move synchronously, and longitudinally scrapes and crushes the conditioning agent that is accumulated and clumped at the bottom of the hopper, effectively breaking up bridging and rat holes.

[0020] The top of the crushing ring 6 is fixedly connected to two fixing plates 7. One of the fixing plates 7 has a guide rod 8 fixedly connected to its outer wall. The guide rod 8 provides guidance for the left and right sliding of the crushing ring 6. The outer wall of the discharge bin 1 is fixedly embedded with an oil-free bushing 9. The outer wall of the guide rod 8 is slidably connected to the inner wall of the oil-free bushing 9.

[0021] Two crushing V-shaped plates 10 are fixedly connected to the inner wall of the crushing ring 6. A frame is fixedly connected to the outer wall of the feeding bin 1. A hydraulic cylinder 11 is fixedly connected to the top of the frame. A sliding hole is opened on the outer wall of the feeding bin 1. The inner wall of the sliding hole is slidably connected to the outer wall of the output end of the hydraulic cylinder 11. The outer wall of the output end of the hydraulic cylinder 11 is fixedly connected to the outer wall of another fixed plate 7.

[0022] The bottom of the feeding hopper 1 is equipped with a feeding assembly, which includes a discharge pipe 12. The bottom of the feeding hopper 1 is fixedly connected to the top of the discharge pipe 12. The bottom of the discharge pipe 12 is fixedly connected to a connecting pipe 13. The discharge pipe 12 can guide the crushed conditioner smoothly into the connecting pipe 13 to avoid stagnation and agglomeration at the transition point. The inner walls of the discharge pipe 12 and the connecting pipe 13 are smooth. The bottom of the connecting pipe 13 is fixedly connected to a screw conveyor 14. The screw conveyor 14 pushes the material through the rotation of the screw blades and can control the amount of conditioner added. The outer wall of the screw conveyor 14 is fixedly connected to a feeding pipe 15.

[0023] Working principle: During the conditioner feeding process, when powdered or easily hygroscopic conditioner bridges or clogging at the bottom of the feeding hopper 1, the hydraulic cylinder 11 is activated. Its output end pushes the fixed plate 7 that is fixedly connected to it, which drives the breaking ring 6 to move horizontally back and forth along the inner wall of the feeding hopper 1. The guide rod 8 slides in the two oil-free bushings 9 to ensure smooth movement and reduce friction and wear. The two V-shaped breaking plates 10 fixed on the inner wall of the breaking ring 6 move back and forth synchronously with it, repeatedly scraping, squeezing and shearing the blocked material, effectively destroying the coal arch or rat hole structure and restoring the material flowability. After unblocking, the conditioning agent enters the discharge pipe 12 through the bottom of the feeding hopper 1, and then is sent to the screw conveyor 14 through the connecting pipe 13. The screw conveyor 14 pushes the material quantitatively to the discharge pipe 15 for discharge, thus achieving continuous and stable material supply. The entire device is fixed to the support structure by two mounting bases 5. The annular rib plate 2 and the top ring 3 enhance the overall rigidity of the feed hopper 1, and the material frame 4 provides bottom support.

[0024] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the hydraulic cylinder 11 and the screw conveyor 14 to facilitate the control of the overall operation.
