Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for automotive parts processing, and in particular to a dust removal device for polishing automotive parts. Background Technology

[0002] Automotive parts, also known as automotive components or spare parts, refer to all components, assemblies, and accessories used for automotive assembly, repair, maintenance, and performance upgrades. Its scope is extremely broad, covering everything from core operating components (such as engines, transmissions, and chassis), key components that ensure vehicle safety and normal operation (such as brake pads, shock absorbers, and tires), to various filters, spark plugs, and other easily worn and consumable parts, as well as all products including in-vehicle electronic equipment, interior parts, and exterior parts.

[0003] In the manufacturing and processing of automotive parts, grinding is a common surface treatment step used to remove burrs, scratches, and other defects from the surface of the parts. However, grinding generates a large amount of dust, which not only pollutes the working environment and endangers the health of operators, but may also adhere to the surface of the automotive parts, affecting the accuracy of subsequent processing and product quality. Existing dust removal devices for grinding automotive parts mostly use a suction fan in conjunction with a filter structure to collect dust. The suction fan draws the dust generated during grinding into the filter structure, which then filters and intercepts the dust. However, traditional dust removal equipment often uses fixed filter plates or cartridges, which have limited contact area between the filter material and the dusty air. Furthermore, the airflow tends to concentrate in localized areas of the filter structure, leading to excessive load on the filter material in certain areas. This not only results in low single-pass filtration efficiency but also accelerates dust accumulation on the filter material surface. Manual cleaning is required later, which is time-consuming, labor-intensive, and reduces overall processing efficiency.

[0004] Therefore, this application provides a dust removal device for polishing automotive parts to meet the requirements. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background art, and to propose a dust removal device for polishing automotive parts.

[0006] The technical problem to be solved by this utility model is to provide a dust removal device for grinding automotive parts, which solves the problem that the filter structure of traditional dust removal equipment is mostly a fixed filter plate or filter cylinder. The filter material has a limited contact area with the dust-laden air and the airflow is prone to local concentration, resulting in excessive load on the filter material in some areas. This not only leads to low single-pass filtration efficiency and accelerated dust accumulation, but also requires manual shutdown for cleaning, which is time-consuming, labor-intensive and reduces the overall processing efficiency.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A dust removal device for polishing automotive parts includes a dust collection box. An exhaust port is provided on the inner wall of one side of the dust collection box. A high-pressure centrifugal fan is detachably connected to the surface of the dust collection box outside the exhaust port. A dust filter assembly capable of automatic dust removal is provided at one end of the dust collection box relative to the exhaust port. An air inlet is provided above the dust filter assembly and at the upper end of the surface of the dust collection box on the side opposite to the exhaust port. The air inlet is interconnected with a dust suction hood provided on the polishing table through an air guide pipe.

[0008] Preferably, the dust filtration assembly includes a servo motor, a first pulley, a second pulley, a transmission rod, a beater belt, a metal mesh frame, and a filter cartridge. The upper end of the dust collection box is rotatably provided with a metal mesh frame, and the filter cartridge is nested inside the metal mesh frame. The servo motor is detachably nested on the side of the dust collection box opposite to the exhaust port and at a position corresponding to the metal mesh frame. The power output end of the servo motor is detachably fixed to one end of the metal mesh frame. The dust collection box surfaces on both sides of the servo motor are respectively rotatably nested with a first pulley and a second pulley. A transmission rod is rotatably provided inside both the first pulley and the second pulley, and the transmission rod is located on both sides of the metal mesh frame. Beater belts are interlaced and fixedly connected to the surface of the transmission rod.

[0009] Preferably, the surface of the servo motor power output end is provided with two sets of belt grooves, the inner cavity of the belt grooves is fitted with a transmission belt, and the other side of the transmission belt is respectively fitted onto the surface of the first pulley and the second pulley.

[0010] Preferably, a mounting base is fixedly connected to the surface of the dust collection box below the servo motor, and the servo motor is detachably connected to the upper surface of the mounting base.

[0011] Preferably, the dust collection box has an air outlet cavity on one side of the high-pressure centrifugal fan, and the air outlet cavity is interconnected with the exhaust port. A Venturi tube inducer is nested inside the air outlet cavity, and the Venturi tube inducer is interconnected with the filter cartridge.

[0012] Preferably, an air chamber is provided on the surface of the dust collection box above the air outlet cavity, and a pulse jet pipe is interconnected on one side of the air chamber, with the air outlet end of the pulse jet pipe located outside the Venturi tube inducer.

[0013] Preferably, the bottom of the inner cavity of the dust collection box is provided with a dust collection groove, and the inner cavity of the dust collection groove is provided with a collection box that can be detached, washed and slidably.

[0014] Preferably, a support rod is fixedly connected around the lower surface of the dust collection box, and a base is fixedly connected to the bottom end of the support rod. An inspection door is detachably connected to one end of the upper surface of the dust collection box.

[0015] In the above solution, the servo motor drives the metal mesh frame and the inner filter cartridge to rotate stably. After the dust-laden air enters the dust collection box from the air inlet, it can flow evenly through the rotating metal mesh frame and the filter cartridge. The filter cartridge fully intercepts the dust, and the filtered clean air is discharged. The rotating filter cartridge can increase the contact area between the filter material and the dust-laden air, avoid local overload, and improve the single-pass filtration efficiency. At the same time, the servo motor drives the first and second pulleys on both sides to rotate through the transmission belt, so that the transmission rod and the surface tapping belt operate synchronously. When the filter cartridge rotates, it taps the surface of the metal mesh frame evenly, shaking the dust off into the dust collection box, realizing automatic cleaning of the filter material. This solves the problem of operation interruption caused by manual cleaning in traditional devices, ensures the continuity of grinding and dust removal, and effectively ensures the stability and efficiency of dust removal.

[0016] In the above solution, when the filter cartridge becomes clogged after prolonged use, the air tank stores high-pressure gas, which is then sprayed into the filter cartridge via a pulse jet pipe to perform backwash cleaning. The filter cartridge rotates continuously under the drive of a servo motor, ensuring that the pulse airflow evenly covers the filter material without dead corners, thus ensuring thorough cleaning. At the same time, during the backwash cleaning process, automatic tapping cleaning can shake off some dust as the filter material rotates, significantly reducing dust accumulation. This reduces the frequency of pulse cleaning, thereby ensuring dust removal effect while also effectively reducing costs and improving the practicality of the device. Attached Figure Description

[0023] Please see Figure 1-4 A dust removal device for grinding automotive parts includes a dust collection box 3. An exhaust port 5 is provided on the inner wall of one side of the dust collection box 3. A high-pressure centrifugal fan 6 is detachably connected to the surface of the dust collection box 3 outside the exhaust port 5. A dust filter assembly 11 capable of automatic dust removal is provided at one end of the dust collection box 3 opposite to the exhaust port 5. An air inlet 12 is provided above the dust filter assembly 11 and on the upper surface of the dust collection box 3 opposite to the exhaust port 5. The air inlet 12 is interconnected with a dust suction hood installed on the grinding table via an air guide pipe. The dust collection box 3, through the high-pressure centrifugal fan 6 at the exhaust port 5, the automatically dust-removing dust filter assembly 11 at the opposite end, and the air inlet 12 above the dust filter assembly 11 communicating with the dust suction hood of the grinding table, constructs a complete dust treatment path of suction, filtration, and exhaust. This allows grinding dust to efficiently enter the dust collection box 3, be filtered by the dust filter assembly 11, and then discharged, effectively ensuring stable dust removal.

[0024] Furthermore, the dust filtration assembly 11 includes a servo motor 111, a first pulley 112, a second pulley 113, a transmission rod 114, a striking belt 115, a metal mesh frame 116, and a filter core 117. The metal mesh frame 116 is rotatably mounted on the upper end of the inner cavity of the dust collection box 3, and the filter core 117 is nested within the inner cavity of the metal mesh frame 116. The servo motor 111 is detachably nested on one side of the dust collection box 3 opposite to the exhaust port 5 and at a position corresponding to the metal mesh frame 116. The power output end of the servo motor 111 is detachably fixed to one end of the metal mesh frame 116. The first pulley 112 and the second pulley 113 are rotatably nested on the surfaces of the dust collection box 3 on both sides of the servo motor 111. A transmission rod 114 is rotatably mounted inside both the first pulley 112 and the second pulley 113, and the transmission rod 114 is located within the metal mesh frame 116. On both sides, the transmission rods 114 are fixedly connected with interlaced striking belts 115. The power output end of the servo motor 111 has two sets of belt grooves 118. The inner cavity of the belt grooves 118 is fitted with a transmission belt 119, and the other side of the transmission belt 119 is respectively fitted onto the surface of the first pulley 112 and the second pulley 113. By detachably fixing the servo motor 111 to the metal mesh frame 116, and by using the transmission belt 119 to link the first and second pulleys 113 and the transmission rods 114, the servo motor 111 can drive the metal mesh frame 116 of the nested filter core cylinder 117 to rotate to expand the contact area between the filter material and the dusty air and improve the filtration efficiency. It can also drive the transmission rods 114 and the striking belts 115 on both sides to rotate synchronously and strike the filter core cylinder 117 evenly to achieve automatic dust removal, avoid easy clogging, and ensure the stability of dust removal.

[0025] Furthermore, a mounting base 10 is fixedly connected to the surface of the dust collection box 3 below the servo motor 111, and the servo motor 111 is detachably connected to the upper surface of the mounting base 10; by supporting the servo motor 111 with the mounting base 10, the stability of the servo motor 111 during use can be ensured, and the rotation accuracy of the dust filter assembly 11 can be avoided due to vibration displacement during motor operation.

[0026] Furthermore, an air outlet chamber 13 is provided inside the dust collection box 3 and on one side of the high-pressure centrifugal fan 6. The air outlet chamber 13 is interconnected with the exhaust port 5. A Venturi tube inducer 15 is nested inside the air outlet chamber 13 and is interconnected with the filter cartridge 117. An air bag 4 is provided on the surface of the dust collection box 3 above the air outlet chamber 13. A pulse jet pipe 14 is interconnected on one side of the air bag 4, and the air outlet of the pulse jet pipe 14 is located outside the Venturi tube inducer 15. The Venturi tube inducer 15 optimizes the flow efficiency of the filtered clean air, ensuring stable airflow discharge. It also allows the high-pressure airflow ejected by the pulse jet pipe 14 to act more accurately on the filter cartridge 117. Combined with the airflow guiding effect of the Venturi tube inducer 15, it enhances the backwash cleaning force, further improves the filter material cleaning effect, and ensures long-term stable operation of the device.

[0027] Furthermore, a dust collection trough 7 is provided at the bottom of the inner cavity of the dust collection box 3, and a collection box 8 is detachably and slidably provided inside the dust collection trough 7; by using the dust collection trough 7 at the bottom of the inner cavity of the dust collection box 3 in conjunction with the detachably and slidably provided collection box 8, the dust that is shaken off can be collected in a concentrated manner, and the collection box 8 can be directly pulled out for cleaning or washing, which effectively improves the convenience of use.

[0028] Furthermore, support rods 2 are fixedly connected around the lower surface of the dust collection box 3, and a base 1 is fixedly connected to the bottom of the support rods 2. An inspection door 9 is detachably connected to one end of the upper surface of the dust collection box 3. The lower surface of the dust collection box 3 is connected to the base 1 through the support rods 2, which can provide stable support for the device and prevent the device from shifting due to vibration during grinding operations, ensuring the smooth progress of the dust removal process. At the same time, the inspection door 9 detachably connected to one end of the upper surface of the dust collection box 3 makes it convenient for staff to regularly open and inspect the internal dust filter components 11 and clean any abnormalities, reducing the difficulty of maintenance operations and further improving the ease of use of the device.

[0029] Working principle: During dust removal, the high-pressure centrifugal fan 6 starts running first. The dust-laden air generated by the grinding table enters the air duct through the dust hood under the action of suction, and then enters the interior of the dust collection box 3 through the air inlet 12 at the top of the dust collection box 3. At this time, the servo motor 111 starts synchronously, and its power output end drives the metal mesh frame 116 and the filter core 117 in the inner cavity to rotate stably. The dust-laden air flows evenly through the rotating metal mesh frame 116 and the filter core 117. The filter core 117 fully intercepts the dust in the air, and the filtered clean air enters the air outlet 13 on one side of the dust collection box 3 and is discharged by the high-pressure centrifugal fan 6 through the exhaust port 5. During the rotation of the filter cartridge 117, the servo motor 111 also drives the first pulley 112 and the second pulley 113 on both sides to rotate synchronously through the transmission belt 119, thereby causing the transmission rod 114 and the tapping belt 115 fixed on the surface to operate synchronously. The tapping belt 115 taps the rotating filter cartridge 117 surface and the metal mesh frame 116 evenly, shaking the attached dust into the collection box 8 of the dust collection trough 7 below, realizing automatic cleaning of the filter material, avoiding the impact of dust accumulation on filtration efficiency, and at the same time, there is no need for manual shutdown for cleaning, ensuring continuous grinding and dust removal operations. When the filter cartridge 117 shows signs of blockage after prolonged use, the air tank 4 releases the stored high-pressure gas and sprays high-pressure airflow into the filter cartridge 117 through the pulse jet pipe 14 for backwash cleaning. The filter cartridge 117 continues to rotate under the drive of the servo motor 111, so that the pulse airflow can evenly cover every area of ​​the filter material, avoiding cleaning dead corners and ensuring that the filter cartridge 117 is thoroughly cleaned. During this process, automatic tapping cleaning is also carried out simultaneously, continuously shaking off some dust to reduce accumulation and effectively reducing the frequency of pulse cleaning. During the later cleaning, the collection box 8 in the dust collection tank 7 is removed to clean the dust. After cleaning, it can be reinstalled for continued use. This not only ensures the stability and efficiency of dust removal but also reduces operating costs, making it suitable for the long-term operation needs of automotive parts grinding workshops.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
