Description

Technical Field

[0001] This utility model relates to the field of auxiliary device technology, and in particular to a feeding auxiliary device for a mechanical crusher. Background Technology

[0002] In mechanical crushing and processing, feeding auxiliary devices have become indispensable components to ensure that powder materials can enter the crusher stably and efficiently for processing. Among them, screw feeding auxiliary devices are widely used in the industry due to their conveying and propulsion capabilities. However, in actual operation, conventional screw feeding auxiliary devices have poor adaptability for powder materials with high viscosity and high moisture content. During the conveying process, these materials are prone to adhesion and accumulation on the surface of the screw conveyor blades due to their physical properties, and material bridging can easily form on the inner wall of the feed channel, leading to blockage of the feed channel. Once blockage occurs, not only is it necessary to stop the machine for manual cleaning, interrupting the normal production process, but the blocked material may also deteriorate due to prolonged retention, affecting the quality of the final product.

[0003] Meanwhile, in the structural design of conventional screw feed auxiliary devices, a small gap is often required between the outer wall of the screw and the inner wall of the feed inlet to ensure conveying efficiency. However, this design makes them prone to friction and collision during operation. Long-term friction will accelerate the wear rate of the outer wall of the screw and the inner wall of the feed inlet, which will not only reduce the conveying accuracy of the equipment, but also require regular replacement and maintenance of worn screw components, significantly increasing the maintenance cost and downtime of the equipment.

[0004] Furthermore, the internal structure of traditional screw feed auxiliary devices is relatively complex, with many dead zones. These dead zones easily trap material debris during material conveying. When cleaning the device, it is difficult for workers to thoroughly clean these dead zones. This can lead to the deterioration of residual material, affecting the quality of subsequently conveyed materials. Moreover, when switching to conveying different types of materials, the mixing of residual and new material can easily cause cross-contamination. Therefore, this device is unsuitable for production sites with high material change frequencies, limiting its applicability. In view of this, this utility model proposes a feeding auxiliary device for a mechanical crusher. Utility Model Content

[0005] The purpose of this invention is to address the problems of conventional spiral feeding auxiliary devices used in current mechanical crushers, which are prone to material adhesion and accumulation, bridging and blockage at the feed inlet, rapid wear due to friction, high maintenance costs, difficulty in cleaning, and easy deterioration or cross-contamination of materials, thus limiting their applicability. This invention proposes a feeding auxiliary device for mechanical crushers.

[0006] The technical solution of this utility model is as follows: A feeding auxiliary device for a mechanical crusher includes a feeding assembly, which includes a feeding hopper. Multiple sets of inclined plates are arranged at the bottom of the feeding hopper. The multiple sets of inclined plates are connected to a discharge pipe via flanges. A discharge pipe is connected to the bottom of the discharge pipe, and one end of the discharge pipe is connected to the crusher via a flange. A pneumatic auxiliary mechanism is connected to the end of the discharge pipe away from the crusher. The pneumatic auxiliary mechanism outputs compressed gas to assist in material discharge. An intermittent exhaust assembly is arranged in the pneumatic auxiliary mechanism. The intermittent exhaust assembly is used for intermittent discharge of compressed gas. A vibrating motor is installed on the side of the feeding hopper to generate vibration to prevent material blockage.

[0007] Optionally, a cover plate is fixedly connected to the top of the feed hopper, and a feed pipe communicating with the inside of the feed hopper is installed on the top of the cover plate. The feed pipe is connected to the feeding equipment via a flexible hose.

[0008] Optionally, both the discharge pipe and the outlet pipe are provided with a ceramic lining.

[0009] Optionally, the pneumatic auxiliary mechanism includes a vacuum compressor, the output end of which is connected to an air pipe via a flange, a connector is connected to the end of the air pipe away from the vacuum compressor, a nozzle is threaded onto the connector, a connecting disc is threaded onto the outer ring of the nozzle, the connecting disc is connected to a flange at one end of the discharge pipe, and one end of the nozzle is located in the discharge pipe.

[0010] Optionally, the connecting plate has a stepped hole that communicates with the air pipe, and the inner diameter of the stepped hole is smaller on the side closer to the discharge pipe.

[0011] Optionally, a pressure regulating valve is provided on the air pipe.

[0012] Optionally, the intermittent exhaust assembly includes a connecting block, in which an air passage is opened. Connecting pipes communicating with the air passage are fixedly connected to both sides of the connecting block, and the two sets of connecting pipes are respectively connected to the output end of the vacuum compressor and one end of the air pipe through flanges.

[0013] Optionally, a baffle is slidably connected to the connecting block. The baffle is located in the middle of the airway. A cavity is provided on one side of the baffle in the connecting block. A slide plate is slidably connected to the cavity. The slide plate is fixedly connected to one end of the baffle. Multiple sets of synchronizing rods are fixedly connected to the side of the slide plate away from the baffle. One end of the multiple sets of synchronizing rods extends to the outside of the connecting block and is fixedly connected to a moving block. All of the multiple sets of synchronizing rods are slidably engaged with the connecting block.

[0014] Optionally, a mounting plate is fixedly connected to the side of the connecting block near the moving block. The mounting plate is L-shaped and a servo motor is mounted on the mounting plate. The output end of the servo motor passes through the mounting plate and is fixedly connected to a turntable. A rotating column is fixedly connected to the side of the turntable near the moving block. A sliding groove is provided in the moving block, and the rotating column is slidably connected in the sliding groove.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This invention uses a vibrating motor installed on the side of the feed hopper to generate vibration, which can prevent highly viscous and moist materials from sticking and accumulating on the inclined plate surface. At the same time, the compressed gas output from the vacuum compressor in the pneumatic auxiliary mechanism is gathered through the nozzle and the stepped holes of the connecting plate, which can capture the material and form a gas-solid two-phase flow to accelerate the conveying. Combined with the intermittent exhaust component, the pulse exhaust achieved by the servo motor driving the baffle to move back and forth creates an intermittent impact force on the material, further avoiding blockage in the discharge pipe, eliminating the need for frequent shutdowns for cleaning, ensuring continuous production process, reducing the risk of material retention and deterioration, and improving the quality of the final product.

[0017] Furthermore, the pressure regulating valve on the air pipe in the pneumatic auxiliary mechanism has both filtering and pressure regulating functions, which can ensure the cleanliness of compressed gas and the uniformity of feeding, and avoid the impact of unstable air pressure on the conveying accuracy. At the same time, the entire device is connected to key components through flanges, which makes disassembly and assembly convenient and has no complex dead corner structure, reducing material residue and lowering the risk of cross-contamination. It is suitable for production sites with high material change frequency, expanding the scope of application, while reducing the need for component wear and maintenance, and reducing equipment maintenance costs and downtime.

[0018] In summary, this utility model not only ensures continuous production and improves product quality, but also reduces maintenance costs and expands the scope of application, effectively addressing the pain points of traditional equipment. Attached Figure Description

[0033] Example

[0034] like Figure 1 and Figure 2 As shown, this utility model proposes a feeding auxiliary device for a mechanical crusher, including a feeding assembly 1. The feeding assembly 1 includes a feeding hopper 11, and multiple sets of inclined plates 12 are provided at the bottom of the feeding hopper 11 to ensure slow material feeding. The multiple sets of inclined plates 12 are connected to a discharge pipe 13 via flanges. The bottom of the discharge pipe 13 is connected to a discharge pipe 14, one end of which is connected to the crusher via a flange, facilitating material entry into the crusher. Both the discharge pipe 13 and the discharge pipe 14 have ceramic linings on their inner walls, which can reduce the erosion and wear of the material against the inner wall of the pipe after airflow, reducing the risk of metal foreign objects being generated. A cover plate 15 is fixedly connected to the top of the feed hopper 11. A feed pipe 16, which communicates with the inside of the feed hopper 11, is installed on the top of the cover plate 15. The feed pipe 16 is connected to the feeding equipment via a flexible hose. The upper end of the flexible hose is connected to the feeding device, such as a rotary valve, star-shaped discharge valve, or screw feeder, via a clamp or other means. The lower end is connected to the feed pipe 16 via a clamp or other means, which serves as a buffer, facilitating the removal of the pipe fittings later and allowing production personnel to easily observe the material feeding situation. A vibration motor 4 is installed on the side of the feed hopper 11. The vibration motor 4 is used to generate vibration to prevent material blockage and ensure that material does not accumulate or clog above the inclined plate 12.

[0035] For further details, please refer to Figure 1 and Figure 2The aforementioned auxiliary device also includes a pneumatic auxiliary mechanism 2 connected to the end of the discharge pipe 14 away from the crusher. The pneumatic auxiliary mechanism 2 is used to output compressed gas to assist in the discharge of materials. The pneumatic auxiliary mechanism 2 includes a vacuum compressor 21. The output end of the vacuum compressor 21 is connected to a gas pipe 22 via a flange. The end of the gas pipe 22 away from the vacuum compressor 21 is connected to a connector 23. A nozzle 24 is threaded onto the connector 23. A connecting plate 25 is threaded onto the outer ring of the nozzle 24. The connecting plate 25 is connected to a flange at one end of the discharge pipe 14. One end of the nozzle 24 is located in the discharge pipe 14, facilitating the entry of compressed gas from the output end of the vacuum compressor 21 into the discharge pipe 14. The compressed gas is gathered by the nozzle 24, instantly capturing and mixing the discharged material to form a gas-solid two-phase flow. This two-phase flow is accelerated in the feed inlet of the equipment and injected into the crusher cavity at a high speed, thereby achieving feeding. A stepped hole communicating with the gas pipe 22 is opened in the connecting plate 25, and the inner diameter of the stepped hole is smaller on the side closer to the discharge pipe 14, which is used to gather the compressed gas. A pressure regulating valve 26 is installed on the air pipe 22. The pressure regulating valve 26 has a filtering function, which can filter the compressed air and adjust the amount of compressed air to ensure uniform feeding of the equipment.

[0036] Furthermore, such as Figure 3 and Figure 4As shown, the auxiliary device also includes an intermittent exhaust assembly 3 disposed in the pneumatic auxiliary mechanism 2. The intermittent exhaust assembly 3 is used for the intermittent discharge of compressed gas. The intermittent exhaust assembly 3 includes a connecting block 31, in which an air passage 32 is opened. Connecting pipes 33 communicating with the air passage 32 are fixedly connected to both sides of the connecting block 31. The two sets of connecting pipes 33 are respectively connected to the output end of the vacuum compressor 21 and one end of the air pipe 22 through flanges. The gas output by the vacuum compressor 21 enters the air pipe 22 after passing through the air passage 32. A baffle 34 is slidably connected in the connecting block 31. The baffle 34 is located in the middle of the air passage 32. When the baffle 34 is blocking the air passage 32, it prevents compressed air from passing through. When the baffle 34 is removed, the compressed air passes through normally. A cavity 35 is provided on one side of the baffle 34, which is opened in the connecting block 31. A sliding plate 36 is slidably connected in the cavity 35. The sliding plate 36 is fixedly connected to one end of the baffle 34. When the sliding plate 36 moves, it drives the baffle 34 to move synchronously. Multiple sets of synchronizing rods 37 are fixedly connected to the side of the slide plate 36 away from the baffle 34. One end of each set of synchronizing rods 37 extends to the outside of the connecting block 31 and is fixedly connected to a moving block 38. When the moving block 38 moves, it drives the slide plate 36 to move via the synchronizing rods 37. All sets of synchronizing rods 37 are in sliding engagement with the connecting block 31, and the movement of the moving block 38 and the slide plate 36 is smooth under the limiting action of the synchronizing rods 37. A mounting plate 39 is fixedly connected to the side of the connecting block 31 near the moving block 38. The mounting plate 39 is L-shaped and a servo motor 310 is mounted on the mounting plate 39. The output end of the servo motor 310 passes through the mounting plate 39 and is fixedly connected to a turntable 311. After the servo motor 310 starts, it drives the turntable 311 to rotate. A rotating column 312 is fixedly connected to the side of the turntable 311 near the moving block 38. When the turntable 311 rotates, it drives the rotating column 312 to perform circular motion. The movable block 38 is provided with a slide groove 313, and the rotating column 312 is slidably connected in the slide groove 313. When the rotating column 312 performs circular motion, it slides in the slide groove 313, thereby driving the movable block 38 to perform reciprocating motion, thereby driving the baffle 34 to perform reciprocating motion, realizing intermittent exhaust, and further preventing material blockage by the impact force on the material during intermittent exhaust.

[0037] In this embodiment, the feeding device is connected to the feed pipe 16 via a flexible hose. Both ends of the hose are fixed to the feeding device and the feed pipe 16 respectively with clamps, achieving both material buffering and facilitating observation of the feeding process by the operator. The material enters the feed hopper 11, sealed by a cover plate 15, through the feed pipe 16. The cover plate 15 prevents dust generation during material transport and ensures a stable internal environment within the feed hopper 11. The vibration motor 4 mounted on the side of the feed hopper 11 vibrates upon startup, preventing material from adhering and accumulating on the surface of the inclined plate 12 at the bottom of the feed hopper 11. The inclined plate 12 is tilted, and in conjunction with the vibration effect of the vibration motor 4, it causes the material to move slowly and evenly towards the discharge pipe 13, preventing blockage of subsequent channels due to excessively rapid material descent. The material then enters the discharge pipe 13, connected by a flange, through the inclined plate 12, and then flows through the discharge pipe 13 into the lower discharge pipe 14. One end of the discharge pipe 14 is connected to the crusher via a flange, providing a channel for the material to enter the crusher.

[0038] After the material enters the discharge pipe 14, the vacuum compressor 21 outputs compressed gas. The compressed gas is transported to the connector 23 via the gas pipe 22, and then enters the discharge pipe 14 through the nozzle 24 threaded on the connector 23. The connecting plate 25 is connected to the flange at one end of the discharge pipe 14. The stepped holes inside the plate can initially gather the compressed gas. Combined with the gathering effect of the nozzle 24, the compressed gas can accurately act on the material in the discharge pipe 14, instantly capturing and mixing the material to form a gas-solid two-phase flow. The pressure regulating valve 26 on the gas pipe 22 can filter the compressed gas and adjust the gas pressure to ensure a stable output of the gas-solid two-phase flow and avoid uneven feeding due to excessive or insufficient gas pressure.

[0039] Simultaneously, after the servo motor starts, it drives the turntable 311 at the output end to rotate, and the rotating column 312 on the turntable 311 moves in a circular motion with the turntable 311. The rotating column 312 is slidably connected in the groove 313 of the moving block 38, and during the circular motion, it will push the moving block 38 to reciprocate. The moving block 38 drives the slide plate 36 to slide back and forth in the cavity 35 through multiple sets of synchronous rods 37, which in turn drives the baffle 34 to move back and forth. When the baffle 34 is removed, the compressed gas output by the vacuum compressor 21 passes through the connecting pipe 33. When the baffle 34 blocks the air passage 32, the gas delivery is temporarily interrupted, realizing the intermittent discharge of compressed gas. The intermittently discharged compressed gas forms a pulse impact force on the material in the discharge pipe 14, which can further prevent the material from sticking and blocking in the discharge pipe 14, ensuring that the gas-solid two-phase flow can be injected into the crusher cavity at a stable speed to complete the entire feeding process.

[0040] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
