Description

Technical Field

[0001] This utility model belongs to the technical field of crushing equipment, and specifically relates to a discharge mechanism of a crusher. Background Technology

[0002] In industrial production, pulverizers, as important material handling equipment, are widely used in various industries such as chemical, pharmaceutical, and food processing. Their working principle is to crush lumpy materials into powder through their internal structure to meet the particle size requirements of different production processes. However, existing pulverizers suffer from a common problem in the discharge stage that urgently needs to be addressed.

[0003] During the crushing process, materials are processed by the crusher into powder, which is then output through the discharge port. When most of the material is output, dust is easily generated at the discharge port due to the physical properties of powder. This dust not only quickly spreads into the workshop environment, causing a significant increase in dust concentration, but also seriously affects the overall environmental quality of the workshop and reduces workplace comfort.

[0004] Even more seriously, the dust problem is exacerbated when multiple crushing machines operate simultaneously in the workshop. Large amounts of dust in the air not only reduce visibility in the workshop, affecting workers' field of vision and increasing safety hazards during production—such as potential worker misoperation leading to mechanical accidents or fires—but also cause serious harm to workers' respiratory systems and skin with prolonged exposure to high concentrations of dust, leading to occupational diseases such as pneumoconiosis and severely threatening workers' health.

[0005] Currently, although some dust control measures and equipment exist on the market, most suffer from problems such as insufficient targeting and unsatisfactory results, failing to fundamentally solve the problem of dust emission from the pulverizer discharge port. Therefore, designing a pulverizer discharge mechanism that can effectively control dust emission is of great significance for improving the workshop environment, protecting worker health, and enhancing production safety. Summary of the Invention

[0006] To address the shortcomings of the existing technology, this utility model provides a discharge mechanism for a crusher to solve the aforementioned problems.

[0007] The present invention relates to a discharge mechanism for a pulverizer, comprising a first fan connected to the discharge port of the pulverizer, the first fan being connected to a cyclone dust collector via a material inlet pipe, the cyclone dust collector comprising an exhaust port at the top and a discharge port at the bottom, a first support frame being provided below the cyclone dust collector, and a star-shaped unloader connected to the discharge port being provided on the first support frame.

[0008] Furthermore, the cyclone dust collector includes a top exhaust port, which is connected to a secondary filter via a primary exhaust pipe. The secondary filter includes a recovery filter box, which is divided into two independent areas—a post-filter area and a pre-filter area—by a horizontal plate. The primary exhaust pipe is equipped with a one-way valve and connects to the pre-filter area. The horizontal plate has several through holes, each with a filter element extending into the pre-filter area. The recovery filter box is equipped with a secondary exhaust pipe connecting to the post-filter area. A second support frame is provided below the recovery filter box, and a recovery funnel connecting to the pre-filter area is provided at the bottom of the recovery filter box. A recovery bag is provided at the bottom of the recovery funnel.

[0009] Furthermore, the recovery filter box is equipped with a pulse air pipe that connects to the post-filtration zone, the pulse air pipe is equipped with a quick exhaust valve, and the recovery filter box is equipped with a high-pressure air tank connected to the pulse air pipe, the high-pressure air tank including an air compressor.

[0010] Furthermore, a second fan is installed on the secondary exhaust pipe.

[0011] Furthermore, the recycling filter box is equipped with an inspection door, and a sealing strip is provided between the inspection door and the recycling filter box. The filter element is detachably connected to the through hole.

[0012] Furthermore, the inspection door is equipped with an observation window.

[0013] Furthermore, a vertical pipe is provided at the bottom of the recycling funnel, and an annular groove is provided on the vertical pipe. The recycling bag is tied to the annular groove by a rope.

[0017] To better understand this utility model, the embodiments of this utility model will be explained in detail below with reference to the accompanying drawings.

[0018] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all relative to the direction of the text. Figure 1 The directions are based on "front, back, left, right, up, down".

[0019] The present invention discloses a discharge mechanism for a pulverizer, comprising a first fan 2 connected to the discharge port of the pulverizer 1. The first fan 2 plays a crucial role, as it uses strong suction to draw the powdery material that is about to generate dust from the discharge port of the pulverizer 1 into the feeding pipe 3. The feeding pipe 3 serves as a material transport channel, accurately conveying the powdery material to the cyclone dust collector 4.

[0020] The cyclone dust collector 4 is a key dust removal component of the entire discharge mechanism. It has an exhaust port at the top and a discharge port at the bottom. When the material powder enters the cyclone dust collector 4 through the feed pipe 3, under the action of the special internal structure of the cyclone dust collector 4, the material powder gradually sinks to the bottom due to its own gravity, while the air rises and is discharged from the exhaust port. A first support frame 5 is installed below the cyclone dust collector 4, which provides stable support for the cyclone dust collector 4 and ensures that it remains stable during operation. A star-shaped unloader 6 connected to the discharge port is also installed on the first support frame 5. The star-shaped unloader 6 can accurately control the discharge rate of the material, so that the material is discharged at a stable and uniform speed, avoiding the generation of dust again during the discharge process.

[0021] Furthermore, the exhaust port of the cyclone dust collector 4 is connected to a secondary filter 8 via a primary exhaust pipe 7. The secondary filter 8 is designed to further filter air that may still contain a small amount of dust after being processed by the cyclone dust collector 4. The secondary filter 8 includes a recovery filter box, which is internally divided into two independent areas, a post-filter zone 10 and a pre-filter zone 11, by a horizontal plate 9. The primary exhaust pipe 7 is connected to the pre-filter zone 11 after being equipped with a one-way valve, so that the air discharged from the cyclone dust collector 4 first enters the pre-filter zone 11. The horizontal plate 9 has several through holes, each with a filter element 12 extending into the pre-filter zone 11. The filter element 12 is made of a material with high-efficiency filtration performance, capable of intercepting fine dust particles in the air. The air filtered by the filter element 12 enters the post-filter zone 10, while the intercepted dust remains in the pre-filter zone 11. The recovery filter box is equipped with a secondary exhaust pipe 13 connected to the post-filter zone 10, through which the clean air after secondary filtration is discharged. A second support frame 14 is installed below the recycling filter box to provide stable support for the recycling filter box. A recycling funnel 15, connected to the pre-filter zone 11, is installed at the bottom of the recycling filter box. The recycling funnel 15 is used to collect the dust intercepted in the pre-filter zone 11. A recycling bag 16 is installed at the bottom of the recycling funnel 15. Dust falls into the recycling bag 16 through the recycling funnel 15, facilitating subsequent centralized processing and recycling.

[0022] To ensure the optimal filtration performance of the secondary filter 8, a pulse air pipe is installed on the recovery filter box, connecting to the post-filter zone 10. The pulse air pipe is equipped with a quick-release valve, and the recovery filter box also features a high-pressure air tank 17 connected to the pulse air pipe, which includes an air compressor. When it is necessary to clean the dust adhering to the filter element 12, the quick-release valve is opened, and compressed air from the high-pressure air tank 17 is instantly injected into the post-filter zone 10 through the pulse air pipe, creating a powerful airflow impact that shakes off the dust adhering to the filter element 12, causing it to fall into the pre-filter zone 11 and then into the recovery bag 16 through the recovery funnel 15. This pulse cleaning method efficiently and quickly cleans the filter element 12, ensuring the continuous and stable operation of the secondary filter 8.

[0023] A second fan 18 is installed on the secondary exhaust pipe 13. The function of the second fan 18 is to provide power for the airflow in the secondary filter 8, ensuring that the air can pass smoothly through the filter element 12 for filtration and finally be discharged from the secondary exhaust pipe 13. At the same time, the second fan 18 can also adjust the wind speed according to actual needs to meet the filtration requirements under different operating conditions.

[0024] To facilitate maintenance and repair of the secondary filter 8, a maintenance door 19 is provided on the recovery filter box. A sealing strip is installed between the maintenance door 19 and the recovery filter box to effectively prevent air leakage, ensuring the internal sealing of the secondary filter 8 and guaranteeing filtration efficiency. The filter element 12 is detachably connected to the through hole. When the filter element 12 needs to be replaced or cleaned after a period of use, it can be easily removed from the through hole, processed accordingly, and then reinstalled. In addition, an observation window 20 is provided on the maintenance door 19, allowing real-time observation of the internal condition of the recovery filter box, timely detection of filter element 12 blockage, dust collection status, etc., so as to take appropriate measures in a timely manner.

[0025] A vertical pipe 21 is provided at the bottom of the recycling funnel 15, and an annular groove 22 is provided on the vertical pipe 21. The recycling bag 16 is tied to the annular groove 22 by a rope. This design makes the installation and removal of the recycling bag 16 more convenient and quick, and also ensures the tight connection between the recycling bag 16 and the recycling funnel 15, preventing dust leakage.

[0026] The usage and principle of this utility model: When using the discharge mechanism of this crusher 1, first start the crusher 1 to begin crushing the material. After the material is crushed, start the first fan 2, which draws the powder from the discharge port of the crusher 1 into the cyclone dust collector 4 through the feed pipe 3. The powder undergoes initial separation in the cyclone dust collector 4; dust settles to the bottom and is discharged through the star-shaped unloader 6, while air is discharged from the exhaust port into the secondary filter 8. In the secondary filter 8, after deep filtration by the filter element 12, clean air is discharged through the secondary exhaust pipe 13, while dust is intercepted in the pre-filter area 11 and falls into the recovery bag 16 through the recovery funnel 15. During operation, the quick-exhaust valve on the pulse air pipe can be opened as needed to use compressed air from the high-pressure air tank 17 for pulse cleaning of the filter element 12, ensuring filtration efficiency. When maintenance of the secondary filter 8 is required, the internal condition can be observed through the observation window 20 on the inspection door 19. If necessary, the inspection door 19 can be opened to replace or clean the filter element 12. Through the coordinated operation of the above components, the entire discharge mechanism effectively controls dust generation during the discharge process of the crusher 1, improves the workshop environment, and protects the health and safety of workers.
