Description

Technical Field

[0001] This utility model relates to the technical field of flocculant dispensing equipment, and in particular to a flocculant feeding structure. Background Technology

[0002] In wastewater treatment and chemical production processes, flocculants are important chemical agents, and their precise and stable addition is key to ensuring treatment effectiveness. Currently, commonly used flocculant feeding devices adopt a structure combining a silo and a screw conveyor, with the rotation of the screw conveyor achieving quantitative output of flocculants.

[0003] However, flocculants are mostly in powder and granular form, with poor flowability. Some types of flocculants are also highly hygroscopic. When stored in a silo for a long time and in a humid environment, the flocculant will absorb moisture and clump together, or form lumps under its own weight. These lumps will accumulate near the discharge port at the bottom of the silo, forming stable "bridging" and "arching" phenomena. Once "bridging" occurs, the screw conveyor below will not be able to pick up the material, even if it is still running, resulting in interruption of material feeding. This directly affects the stability and processing effect of subsequent processes. Existing technologies require manual intervention by operators, such as tapping the outside of the silo or using tools to poke inside the silo. This method is not only labor-intensive and inefficient, but also poses safety hazards and makes it difficult to achieve the requirements of automated and continuous production.

[0004] Therefore, this utility model proposes a flocculant feeding structure to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems that existing flocculant feeding structures have, such as limited functionality, blockage when flocculant clumps or agglomerates, low automation, and insufficient feeding reliability, this utility model aims to provide a flocculant feeding structure with improved structure that can effectively solve the above problems.

[0006] This utility model provides a flocculant feeding structure, including: a hopper, a hopper bottom, a feeding mechanism, a top cover; and an anti-clogging mechanism.

[0007] The anti-blocking mechanism includes a horizontally arranged anti-blocking component and a vertically arranged anti-blocking component.

[0008] Furthermore, the push plate of the horizontally arranged anti-blocking component is slidably disposed on the inner wall of the bottom of the bin, and the vertically arranged anti-blocking component is installed on the top cover, and the components are combined through the synergistic effect of the dual block-breaking structures in the horizontal and vertical directions.

[0009] Preferably, a guide groove is provided on the inner wall of the bin bottom, and a slider that slides in cooperation with the guide groove is provided at the bottom of the push plate.

[0010] Preferably, the flocculant feeding structure also includes a sealing ring between the pusher plate and the bottom of the silo to improve the sealing of the sliding joint and prevent dust leakage.

[0011] Preferably, the fixed end of the vertical electric actuator is installed at the center of the bottom surface of the top cover, and its telescopic end is connected to the breaking push head.

[0012] Preferably, the flocculant feeding structure further includes a fixing frame, which is fixed to the outside of the silo and the bottom of the silo. The lateral electric push rod is installed through the fixing frame, and its telescopic end is connected to the outside of the push plate.

[0013] Preferably, the feeding mechanism further includes a feeding channel, which connects the bottom of the bin to the feeding cylinder.

[0014] Preferably, bearings are provided at both ends of the feeding cylinder, and the rotating shaft is rotatably connected to the feeding cylinder through the bearings to ensure the stability of the rotating shaft.

[0015] Preferably, the feeding mechanism further includes a motor, the output shaft of which is drivenly connected to one end of the rotating shaft to provide power for feeding.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting a pusher plate that can move horizontally back and forth on the inner wall of the silo bottom and a breaking pusher that can impact vertically downward from the top of the silo, forms a dual anti-blocking mechanism with synergistic effect. It solves the problem in the prior art of flocculant blockage at the discharge port due to agglomeration and caking, which affects the continuity of production. It achieves the technical effect of actively breaking up agglomerates, effectively clearing materials, and significantly improving the reliability and continuity of material discharge.

[0017] 2. This utility model solves the problems of low automation, single function, and inability to effectively deal with sudden material blockages in existing devices by using electric actuators to drive the push plate and the breaking push head separately and integrating them with the spiral feeding mechanism. It achieves the technical effect of compact structure, high automation level, automatic block breaking according to the blockage situation, reduced manual intervention, and improved equipment intelligence and applicability.

[0018] 3. This utility model combines the sliding block-breaking method of the horizontal push plate with the impact block-breaking method of the vertical breaking push head, which solves the problem that a single block-breaking method is difficult to deal with the soft blockage caused by compression and the hard blockage caused by moisture at the same time. It achieves the technical effect of graded and efficient treatment of different types of blockage, strong anti-blockage and blockage-clearing ability, and can adapt to more complex material working conditions.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a flocculant feeding structure, which aims to solve the problem of flocculant caking due to moisture and compression, causing feeding blockage in the prior art.

The cooperation structure between the guide groove 32 and the slider 33 provides precise guidance for the reciprocating motion of the push plate 31. A sealing ring 34 is also provided between the push plate 31 and the bin bottom 2. The vertically arranged anti-blocking component is installed on the top cover 37 and includes a breaking push head 39 and a vertical electric push rod 38 that drives the breaking push head 39. The fixed end of the vertical electric push rod 38 is installed at the center of the bottom surface of the top cover 37, and its telescopic end is connected to the breaking push head 39. The lateral electric push rod 36 that drives the push plate 31 is installed by a fixing frame 35 fixed to the outside of the bin 1 and the bin bottom 2. The telescopic end of the lateral electric push rod 36 is connected to the outside of the push plate 31.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: Please refer to Figure 1 and Figure 4 In order to achieve quantitative delivery of flocculant, the internal structure of the feeding mechanism 4 is refined. The feeding mechanism 4 also includes a feeding channel 41 connecting the bottom of the bin 2 and the feeding cylinder 42. The flocculant enters the inside of the feeding cylinder 42 through the feeding channel 41. Bearings 46 are provided at both ends of the feeding cylinder 42. The rotating shaft 44 is rotatably connected to the feeding cylinder 42 through the bearings 46. The propeller blade 43 is fixed on the outside of the rotating shaft 44 and located inside the feeding cylinder 42. The feeding mechanism 4 also includes a motor 45. The output shaft of the motor 45 is driven to one end of the rotating shaft 44, thereby driving the rotating shaft 44 and the propeller blade 43 to rotate stably and realize the pushing of materials.

[0027] Working principle: The hopper 1 is installed at the top of the feeding port, and the hopper bottom 2 is fixed to the bottom of the hopper 1. One end of the feeding channel 41 is connected to the hopper bottom 2, and the other end is connected to the feeding cylinder 42. The bearings 46 of the feeding mechanism 4 are installed at both ends of the feeding cylinder 42. The rotating shaft 44 is fixed to the inner ring of the bearing 46. The propeller blade 43 is fixed to the outside of the rotating shaft 44 and located inside the feeding cylinder 42. The motor 45 is connected to one end of the rotating shaft 44 and fixed with bolts to complete the assembly of the feeding mechanism 4. The bottom of the hopper bottom 2 has guide grooves 32 on its four sides. The push plate 31 of the anti-blocking mechanism 3 is installed on the bottom of the hopper bottom 2. The slider 33 at the bottom of the push plate 31 is embedded in the guide groove 32 on the side wall of the bottom 2 of the silo. A sealing ring 34 is embedded at the interface between the push plate 31 and the bottom 2 of the silo to prevent flocculant leakage. The fixing frame 35 is fixed on the outside of the silo 1 and the bottom 2 of the silo. The top fixed end of the lateral electric push rod 36 is connected to the fixing frame 35. The bottom telescopic end of the lateral electric push rod 36 is connected to the outside of the push plate 31. The top fixed end of the vertical electric push rod 38 is installed at the bottom of the top cover 37. The breaking push head 39 is connected to the bottom output end of the vertical electric push rod 38. The top cover 37 is closed on the top of the silo 1 to complete the overall installation of the device. Before feeding, open the top cover 37 and pour the flocculant into the silo 1. The flocculant falls into the bottom 2 of the silo under gravity and then into the feeding cylinder 42. Start the motor 45. The motor 45 drives the rotating shaft 44 to rotate. The rotating shaft 44 is kept rotating stably through the bearing 46. At the same time, it drives the propeller blade 43 to rotate. The propeller blade 43 pushes the flocculant in the feeding cylinder 42 to be conveyed downward at a uniform speed to achieve quantitative feeding. If the flocculant in bin 1 and bin bottom 2 clumps together, causing a blockage in the feed, the lateral electric actuator 36 is activated. The lateral electric actuator 36 pushes the push plate 31 to move laterally along the guide groove 32. The push plate 31 pushes the flocculant at the bottom of bin bottom 2 to break up the clumps. If the clumps are hard, the vertical electric actuator 38 is activated. The vertical electric actuator 38 drives the breaking push head 39 to move downward. The breaking push head 39 inserts into the flocculant clumps and breaks them up, ensuring that the flocculant can smoothly enter the feed channel 41. After the material is discharged, turn off the motor 45, stop the propeller blade 43 from rotating, clean the flocculant remaining in the silo 1, the feeding channel 41 and the discharge cylinder 42, check whether the sealing ring 34 and the bearing 46 are intact, and replace them in time if there is wear. Cover the top cover 37 to prevent external impurities from entering the silo 1, so as to realize the quantitative discharge of flocculant and the prevention of blockage.
