Description

Technical Field

[0001] This utility model belongs to the technical field of metal surface treatment and environmental protection equipment, and in particular relates to an environmentally friendly shot blasting machine with dust recovery function. Background Technology

[0002] Shot blasting machines are core surface treatment equipment in the production and processing of metal workpieces. They use a high-speed rotating impeller to propel steel shot, iron shot, and other projectiles onto the surface of the workpiece. The impact force of the projectiles removes impurities such as oxide scale, rust, and burrs from the workpiece surface. At the same time, the surface of the workpiece can be strengthened to improve its surface hardness and fatigue strength. They are widely used in automotive parts, mechanical structural parts, ship components, and other fields, providing a qualified workpiece surface base for subsequent painting, assembly, and other processes.

[0003] Most existing shot blasting machines treat dust through a single impeller and a simple filter. This means that a single impeller generates negative pressure, drawing dust through a pipe into a filter box for initial dust removal. While this type of equipment can reduce dust diffusion to some extent, it still has significant limitations. For example, the negative pressure from the single impeller is insufficient, resulting in low dust extraction efficiency. During operation, a large amount of dust still leaks from the inlet and outlet of the shot blasting machine, polluting the workshop environment and being inhaled by operators, harming their respiratory health. Therefore, we propose a dust-recovery environmentally friendly shot blasting machine. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly shot blasting machine with dust recovery. The coordinated design of the recovery device and the screening device solves the problems of low dust extraction efficiency, easy clogging of the filter screen requiring frequent shutdown for cleaning, and difficulty in separating dust and shot fragments, which leads to resource waste in existing shot blasting machines.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an environmentally friendly shot blasting machine with dust recovery, comprising: an equipment base and a shot blasting device, wherein the shot blasting device is fixedly connected to the top of the equipment base, and a recycling device is provided on the top of the equipment base; The recycling device includes a housing, the bottom of which is fixedly connected to the top of a base. A transmission pipe is fixedly connected to the top of the shot blasting equipment, one end of which is fixedly connected to the top of the housing. A drive motor is fixedly connected to the bottom of the inner wall of the housing, and an extraction impeller is fixedly connected to the output end of the drive motor. A rotating sleeve is fixedly connected to the top of the base, and an extraction impeller is rotatably connected to the inner circumferential surface of the rotating sleeve. An intercepting net is fixedly connected to the side of the inner wall of the housing, a scraper is provided on the top of the intercepting net, a transmission rod is fixedly connected to the side of the scraper, a moving block is fixedly connected to one end of the transmission rod, and a crank is slidably connected to the inner wall of the moving block.

[0006] Furthermore, the output shaft of the drive motor is fixedly connected to a drive pulley, and a transmission belt is provided on the circumferential surface of the drive pulley. The drive pulley is fixed to the output shaft of the drive motor, which can stably output the rotational power of the drive motor and provide a power source foundation for the subsequent operation of the second extraction impeller. The transmission belt enables flexible power transmission between the drive pulley and the driven pulley, which can buffer the vibration generated when the drive motor is working, avoid component wear caused by hard connection, and facilitate subsequent adjustment of transmission distance to improve the adaptability of power transmission.

[0007] Furthermore, a driven pulley is fixedly connected to the circumferential surface of the second extraction impeller. The driving pulley is connected to the driven pulley via a transmission belt. The driving pulley drives the driven pulley to rotate synchronously via the transmission belt, which enables the drive motor to drive both the first and second extraction impellers to operate simultaneously. The dual impellers work together to enhance the negative pressure suction inside the device housing, improving the extraction efficiency of dust generated by the shot blasting equipment. Moreover, the belt drive structure is simple, and subsequent maintenance and replacement are convenient, which can reduce equipment operation and maintenance costs and ensure the continuous and stable operation of the recycling device.

[0008] Furthermore, there are two cranks and two moving blocks, which are symmetrical about each other along the vertical central axis of the scraper. There are four transmission rods, which are also symmetrical about each other along the vertical central axis of the scraper. One end of each of the two cranks is fixedly connected to the output shaft of the drive motor and the circumferential surface of the extraction impeller. The two symmetrical cranks and moving blocks can apply driving force synchronously from both sides of the scraper to avoid the scraper tilting or jamming due to force on one side, and to ensure that the scraper always adheres to the surface of the interception net.

[0009] Furthermore, a screening device is provided on the side of the recycling device. The screening device includes a collection box, the side of which is fixedly connected to the side of the device housing. The bottom of the collection box is fixedly connected to the top of the equipment base. A rotating sleeve II is fixedly connected to the top of the equipment base. A bevel gear shaft I is rotatably connected to the inner circumferential surface of the rotating sleeve II. A rotating frame is fixedly connected to the top of the equipment base. A bevel gear shaft II is rotatably connected to the inner circumferential surface of the rotating frame. A cylindrical cam is fixedly connected to the circumferential surface of the bevel gear shaft II. A screening screen is slidably connected to the inner wall of the cylindrical cam. The side of the screening screen is slidably connected to the inner wall of the collection box. A spring is fixedly connected to the side of the screening screen, and one end of the spring is fixedly connected to the inner wall of the collection box.

[0010] Furthermore, the first bevel gear shaft and the second bevel gear shaft mesh with each other, and there are two rotating frames, which are symmetrical about each other along the vertical central axis of the second bevel gear shaft. The meshing of the first bevel gear shaft and the second bevel gear shaft can convert the horizontal rotational power into the vertical rotational power, accurately adapting to the installation direction requirements of the cylindrical cam and realizing efficient conversion of power direction. The two symmetrical rotating frames can provide stable support from both sides of the second bevel gear shaft, reduce the radial runout when the second bevel gear shaft rotates, avoid deviation or jamming at the bevel gear meshing point, ensure the accuracy of power transmission, and lay a stable foundation for the cylindrical cam to drive the screen movement.

[0011] Furthermore, a transmission pulley is fixedly connected to the circumferential surface of the first bevel gear shaft, and a transmission pulley is fixedly connected to the circumferential surface of the second extraction impeller. A belt is provided on the circumferential surface of the second transmission pulley, and the second transmission pulley is connected to the first transmission pulley via the belt. The second transmission pulley is fixed to the second extraction impeller, and the rotational power of the second extraction impeller can drive the first transmission pulley and the first bevel gear shaft to rotate. This allows the screening device and the recycling device to share the same power source, eliminating the need for an additional drive motor, simplifying the overall structure of the equipment and reducing energy consumption. The belt drive ensures that the first and second transmission pulleys rotate synchronously, matching the working rhythm of the screening device with the dust conveying rhythm of the recycling device, preventing dust accumulation in the collection box, and improving screening efficiency and the continuity of dust treatment.

[0012] This utility model has the following beneficial effects: 1. This utility model uses a recycling device consisting of a first extraction impeller, a second extraction impeller, a driving pulley, a driven pulley, and a scraper. The drive motor synchronously drives the two impellers to rotate via a transmission belt, enhancing the negative pressure suction inside the device's casing. This allows for efficient extraction of dust generated during shot blasting operations, reducing dust leakage into the air and minimizing pollution to the working environment. The drive motor and the second extraction impeller respectively drive symmetrical cranks to rotate, and the scraper slides back and forth along the surface of the interception net through a moving block and transmission rod, improving the continuity and reliability of dust recycling.

[0013] 2. This utility model utilizes a power-sharing structure between the screening device and the recycling device. By using the transmission pulley two on the extraction impeller two, the transmission pulley two drives the bevel gear shaft one to rotate via belt drive. The power is then transmitted through the meshing of the bevel gear shaft one and the bevel gear shaft two. This eliminates the need for an additional drive motor for the screening device, simplifying the overall structure of the equipment and reducing energy consumption. The bevel gear shaft two drives the cylindrical cam to rotate, which, in conjunction with the spring, drives the screening screen to slide back and forth in the collection box. This efficiently separates impurities from the dust, facilitating subsequent centralized dust treatment and impurity recycling, thereby improving the precision of dust treatment and resource utilization.

[0024] As shown in the figure, bevel gear shaft 1 43 and bevel gear shaft 2 45 mesh with each other. There are two rotating frames 44, which are symmetrical about each other along the vertical central axis of bevel gear shaft 2 45. The meshing of bevel gear shaft 1 43 and bevel gear shaft 2 45 can convert the horizontal rotational power into the vertical rotational power, which can accurately match the installation direction requirements of cylindrical cam 46 and realize the efficient conversion of power direction. The two symmetrical rotating frames 44 can provide stable support from both sides of bevel gear shaft 2 45, reduce the radial runout when bevel gear shaft 2 45 rotates, avoid deviation or jamming at the bevel gear meshing point, ensure the accuracy of power transmission, and lay a stable foundation for cylindrical cam 46 to drive the screen 47 to move.

[0025] A specific application of this embodiment is as follows: When the drive motor 33 is started, the output shaft of the drive motor 33 synchronously drives the extraction impeller 34 and the driving pulley 312 to rotate. The driving pulley 312 drives the driven pulley 314 to rotate through the transmission belt 313. The driven pulley 314 is linked to the extraction impeller 36 to rotate in the rotating sleeve 35. The extraction impeller 34 and the extraction impeller 36 rotate together so that the dust generated by the shot blasting equipment 2 is sucked into the device housing 31 through the transmission pipe 32. The interception net 37 separates the air and dust. At the same time, the output shaft of the drive motor 33 and the extraction impeller 36 drive the two cranks 311 to rotate respectively. The cranks 311 push the moving block 310 to move back and forth.

The collected dust falls into the collection box 41. When the second impeller 36 rotates, it synchronously drives the second transmission pulley 410 to rotate. The second transmission pulley 410 drives the first transmission pulley 49 to rotate through the belt 411. The first transmission pulley 49 is linked to the first bevel gear shaft 43 to rotate in the second rotating sleeve 42. The first bevel gear shaft 43 meshes with the second bevel gear shaft 45, converting the horizontal rotational power into the vertical rotational power, which drives the second bevel gear shaft 45 to rotate in the rotating frame 44. The second bevel gear shaft 45 drives the cylindrical cam 46 to rotate. The cylindrical cam 46 pushes the screening screen 47 to slide on the inner wall of the collection box 41. The screening screen 47 forms a reciprocating motion on the cylindrical cam 46. The dust falling into the collection box 41 is vibrated by the screening screen 47. Fine dust passes through the screen holes, while impurities are left on the screening screen 47, thus achieving the separation of dust and impurities.
