A high-efficiency dust-removing shot blasting machine

Abstract

This utility model discloses a high-efficiency dust-removing shot blasting machine, including a base, the upper end of which is fixedly connected to the machine body via a support frame; a feed inlet, which is fixedly installed on the upper end of the machine body; and a discharge channel, which is fixedly installed on the lower end of the machine body. When the shot used in this high-efficiency dust-removing shot blasting machine is discharged from the discharge channel, the drive motor is activated, causing the output end of the drive motor to rotate the first gear. When the first gear meshes with the second gear, the first gear will drive the second gear to rotate 90° clockwise. When the tooth surface of the first gear separates from the tooth surface of the second gear, the second gear will reset by the elastic force of the spiral spring. Similarly, when the third gear separates from or meshes with the tooth surface of the first gear, it will also rotate 90° back and forth. Through the rotation of the second and third gears, the dust collectors on both sides are driven to rotate back and forth, absorbing the dust overflowing from the outside of the discharge channel.

Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a high-efficiency dust-removing shot blasting machine. Background Technology

[0002] Shot blasting machines are important equipment widely used for metal surface treatment, rust removal, oxide scale removal, and strengthening. They achieve cleaning or strengthening effects by high-speed blasting of shot (such as steel shot, ceramic shot, etc.) to impact the surface of the workpiece. However, traditional shot blasting machines have the following technical problems during operation:

[0003] 1. Severe dust pollution: Dust generated during shot blasting (including metal shavings, oxide scale, and shot fragments) easily overflows from the discharge port, polluting the working environment and potentially harming the health of operators. Moreover, existing dust removal equipment mostly uses a single dust collection or filtration method, which has low dust removal efficiency and makes it difficult to completely capture the scattered fine dust.

[0004] 2. Incomplete shot recycling: The discharge channel of traditional shot blasting machines usually relies only on gravity separation or simple screen filtration, which causes some shot to mix with dust, affecting the recycling of shot and increasing production costs;

[0005] 3. Insufficient dust suppression measures: Some equipment attempts to suppress dust through spraying, but the spraying range is fixed and cannot be dynamically adjusted, resulting in uneven dust suppression effect and potentially affecting the drying and recycling of pellets;

[0006] 4. Poor flexibility of dust collection components: Most existing dust collection devices use fixed air inlets, which cannot dynamically adjust the dust collection angle according to the direction of dust diffusion, resulting in some dust escaping.

[0007] To address the aforementioned issues, we have made innovative designs based on the existing high-efficiency dust-removing shot blasting machine structure. Utility Model Content

[0008] The purpose of this utility model is to provide a high-efficiency dust-removing shot blasting machine to solve the problems mentioned in the background art, such as serious dust pollution, incomplete shot recovery, insufficient dust reduction measures, and poor flexibility of dust collection components in existing shot blasting machines.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency dust-removing shot blasting machine, comprising a base, the upper end of which is fixedly connected to an organic body via a support frame; a feed inlet, which is fixedly installed on the upper end of the machine body; a discharge channel, which is fixedly installed on the lower end of the machine body, and a filter screen is fixedly installed at the bottom of the discharge channel; a collection box, which is fixedly installed at the tail end of the discharge channel; a dust suction assembly, which is disposed on the left and right sides of the discharge channel; and a spray assembly, which is disposed on the upper end of the discharge channel; wherein, the dust suction assembly is used to absorb dust overflowing from both sides of the discharge channel; and the spray assembly is used to rinse the shot conveyed inside the discharge channel and to suppress dust floating in the air.

[0010] Preferably, the vacuuming assembly includes a drive motor and a first gear. The drive motor is fixedly mounted on the outside of the machine body, and the output end of the drive motor is fixedly connected to the first gear, which is viewed as a half-tooth structure.

[0011] Preferably, the vacuuming assembly further includes a second gear, a third gear, a concentric shaft, and a connecting block. The second gear and the third gear are respectively meshed and connected to the left and right sides of the first gear, and the concentric shaft is fixedly connected to the inner side of the second gear and the third gear. The connecting block is fixedly connected to the left and right sides of the body, and the inner side of the connecting block is rotatably connected to the concentric shaft.

[0012] Preferably, the dust collection assembly further includes a vacuum cleaner, which is fixedly installed at the end of the concentric shaft. Two sets of vacuum cleaners are arranged in a left-right correspondence about the midpoint of the discharge channel, and the initial states of the suction ends of the two sets of vacuum cleaners are respectively set to tilt upward at 45° and downward at 45°.

[0013] Preferably, the dust collection assembly further includes a spiral spring, the two ends of which are respectively connected to the connecting block and the first gear, the connecting block and the second gear.

[0014] Preferably, the spraying assembly includes a support plate, a water tank, a water pump, a water pipe, and a nozzle. The support plate is fixedly installed on the outside of the machine body, and a water tank is fixedly installed on the outside of the support plate. A water pump is fixedly installed on the outside of the water tank, and the output end of the water pump is connected to a nozzle through a water pipe. The nozzle is fixedly installed at the bottom of the support plate, and the nozzle and the discharge channel are distributed vertically in correspondence.

[0015] Preferably, the spraying assembly further includes a collection box, which is fixedly installed on the upper end of the base, and the collection box and the discharge channel are distributed vertically in correspondence.

[0016] Compared with the prior art, the beneficial effect of this utility model is that the high-efficiency dust-removing shot blasting machine is equipped with:

[0017] 1. Dust-collecting structure: When the pellets are discharged from the discharge channel, the drive motor rotates, causing the first gear to rotate. When the first gear meshes with the second gear, the first gear rotates the second gear 90° clockwise. When the first gear tooth surface separates from the second gear tooth surface, the second gear resets due to the elasticity of the spiral spring. Similarly, when the third gear separates from or meshes with the first gear tooth surface, it also rotates 90° back and forth. The rotation of the second and third gears drives the dust collectors on both sides to rotate back and forth, absorbing the dust overflowing from the outside of the discharge channel and increasing the dust collection range, preventing dust from scattering outside the dust collection range and affecting the surrounding environment.

[0018] 2. Spray structure: When the shot is discharged from the inside of the discharge channel, the water pump is running, so that the water inside the water tank is sprayed onto the inside of the discharge channel through the nozzles, thereby washing the shot inside the discharge channel and suppressing the dust floating in the air. The dust generated by washing will fall into the collection box through the filter screen, thus avoiding pollution to the surrounding environment.

[0019] This device uses the combined action of a dust collection component and a spray component to wash a large amount of dust and impurities into the inside of the collection box by the spray component, while the overflowing dust is absorbed by the dust collection component, thereby improving the dust removal effect.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a high-efficiency dust-removing shot blasting machine, comprising:

[0028] Example 1: As Figures 1-5 The present invention provides a technical solution: a high-efficiency dust-removing shot blasting machine, comprising: a base 1, with a body 3 fixedly connected to the upper end of the base 1 via a support frame 2; a feed inlet 4, fixedly installed on the upper end of the body 3; a discharge channel 5, fixedly installed on the lower end of the body 3, with a filter screen 6 fixedly installed at the bottom of the discharge channel 5; a collection box 7, fixedly installed at the tail end of the discharge channel 5; a dust suction assembly 8, disposed on the left and right sides of the discharge channel 5; and a spray assembly 9, disposed on the upper end of the discharge channel 5. The dust suction assembly 8 is used to absorb dust overflowing from both sides of the discharge channel 5; the spray assembly 9 is used to rinse the shot conveyed inside the discharge channel 5 and to reduce dust floating in the air.

[0029] The vacuuming assembly 8 includes a drive motor 801 and a first gear 802. The drive motor 801 is fixedly mounted on the outside of the body 3, and the output end of the drive motor 801 is fixedly connected to the first gear 802. The first gear 802 is viewed as a half-tooth structure. The vacuuming assembly 8 also includes a second gear 803, a third gear 804, a concentric shaft 805, and a connecting block 806. The second gear 803 and the third gear 804 are respectively meshed and connected to the left and right sides of the first gear 802. The concentric shaft 805 is fixedly connected to the inner side of the second gear 803 and the third gear 804. The left and right sides of the body 3 are fixedly connected to the first gear 802. The assembly includes a connecting block 806, with the inner side of the connecting block 806 rotatably connected to the concentric shaft 805; the vacuuming assembly 8 also includes a vacuum cleaner 807, which is fixedly installed at the tail end of the concentric shaft 805, and two sets of vacuum cleaners 807 are arranged in a left-right correspondence about the midpoint of the discharge channel 5, with the initial states of the suction ends of the two sets of vacuum cleaners 807 being tilted upward at 45° and downward at 45° respectively; the vacuuming assembly 8 also includes a spiral spring 808, with both ends of the spiral spring 808 connected to the connecting block 806 and the first gear 802, the connecting block 806 and the second gear 803 respectively;

[0030] When the pellets are discharged from the discharge channel 5, the drive motor 801 is activated, causing the output of the drive motor 801 to rotate the first gear 802. When the first gear 802 meshes with the second gear 803, the first gear 802 will drive the second gear 803 to rotate 90° clockwise. When the tooth surface of the first gear 802 separates from the tooth surface of the second gear 803, the second gear 803 will be reset by the elastic force of the spiral spring 808. Similarly, when the third gear 804 separates from or meshes with the tooth surface of the first gear 802, it will also rotate 90° back and forth. Through the rotation of the second gear 803 and the third gear 804, the vacuum cleaners 807 on both sides will rotate back and forth to absorb the dust overflowing from the outside of the discharge channel 5 and increase the dust collection range, preventing dust from drifting outside the dust collection range and affecting the surrounding environment.

[0031] Example 2: Figures 1-2 The present invention provides a technical solution: a high-efficiency dust-removing shot blasting machine, which discloses that: the spray assembly 9 includes a support plate 901, a water tank 902, a water pump 903, a water pipe 904, and a nozzle 905. The support plate 901 is fixedly installed on the outside of the machine body 3, and the water tank 902 is fixedly installed on the outside of the support plate 901. The water pump 903 is fixedly installed on the outside of the water tank 902, and the output end of the water pump 903 is connected to the nozzle 905 through the water pipe 904. The nozzle 905 is fixedly installed at the bottom of the support plate 901, and the nozzle 905 and the discharge channel 5 are distributed vertically in correspondence. The spray assembly 9 also includes a collection box 906, which is fixedly installed on the upper end of the base 1, and the collection box 906 and the discharge channel 5 are distributed vertically in correspondence.

[0032] When the shot is discharged from the inside of the discharge channel 5, the water pump 903 operates, causing water from the inside of the water tank 902 to be sprayed onto the inside of the discharge channel 5 through the nozzle 905. This washes the shot inside the discharge channel 5 and suppresses dust floating in the air. The dust generated during washing falls into the collection box 906 through the filter screen 6, thus avoiding pollution to the surrounding environment. Through the cooperation of the dust collection component 8 and the spray component 9, a large amount of dust and impurities are washed into the collection box 906 by the spray component 9, while the overflowing dust is absorbed by the dust collection component 8, thereby improving the dust removal effect.
