Description

Technical Field

[0001] The present invention relates to the technical field of grinding, and specifically to an environment-friendly sand suction and dust removal system for workpiece grinding. Background Technique

[0002] Grinding is a kind of surface modification technology. Generally, it refers to a processing method that uses rough objects (such as sandpaper containing high-hardness particles) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. During the grinding process, a large amount of dust is usually generated. These dusts will not only pollute the working environment, but also pose a serious threat to the health of operators, such as causing respiratory diseases and other health problems. The dust removal system for grinding usually includes a filtration system, and the filter plate in this system is a key component, which is responsible for capturing and separating dust particles in the air. However, after the filter plate is used for a period of time, it will be blocked due to the accumulation of dust, resulting in a decrease in filtration efficiency, so it needs to be replaced regularly. At present, there are deficiencies in the replacement of the filter plate in the dust removal devices for grinding on the market. When replacing the filter plate, it is necessary to stop the machine. This approach will not only cause the interruption of the grinding operation, reduce the production efficiency, but also increase the maintenance cost and operation complexity.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 13, the present invention provides a technical solution: an environment-friendly sand suction and dust removal system for workpiece grinding, including a grinding working chamber 1. An attracting connecting pipe 2 is connected to the grinding working chamber 1. A shunt connecting pipe 3 is connected to the attracting connecting pipe 2. Two connecting branch pipes 4 are connected to the shunt connecting pipe 3. A partition sliding plate 5 is slidably connected to each of the two connecting branch pipes 4. A filter plate member 8 is slidably arranged on each of the two connecting branch pipes 4. An attracting pipe 9 is connected to one end of each of the two connecting branch pipes 4 away from the shunt connecting pipe 3. A negative pressure fan 11 is arranged in the attracting pipe 9. An alternating driving member 6 for driving the two partition sliding plates 5 to move in opposite directions is arranged between the two connecting branch pipes 4. A convenient fixing member 7 for limiting and fixing the filter plate member 8 is arranged on the connecting branch pipe 4. A pre-wetting member 10 for wetting the filter plate member 8 is arranged inside the partition sliding plate 5. A storage box is connected to the lower end of the connecting branch pipe 4. A sealing door is arranged on the storage box for collecting the sprayed water and dust. By providing two connecting branch pipes 4 and an alternating driving member 6, the driving gear 65 can be rotated. The driving gear 65 drives the L-shaped tooth plate 66 installed on the connecting branch pipe 4 where the filter plate member 8 to be replaced is located, so that it slides downward, thereby driving one partition sliding plate 5 to move downward to close the air duct of the connecting branch pipe 4. The other L-shaped tooth plate 66 slides upward, driving the partition sliding plate 5 thereon to move upward, realizing the opening of the air duct of the other connecting branch pipe 4, and thus realizing the alternating use of the two connecting branch pipes 4. When one connecting branch pipe 4 is in the working state, the other connecting branch pipe 4 is in the closed state, realizing the replacement of the filter plate member 8 on the closed connecting branch pipe 4 without stopping the machine. Through the cooperation of the partition sliding plate 5 and the pre-wetting member 10, when the partition sliding plate 5 slides downward, the square piston 1010 squeezes the water in the liquid collecting box body 101 through the liquid outlet connecting elbow 104. The water enters the liquid distribution cross pipe 1012 and finally sprays out from the atomizing nozzle 108. The sprayed water is used to wet the filter plate member 8 to reduce the flying of dust when the filter plate member 8 is disassembled and improve the environmental protection performance. Through the cooperation of the partition sliding plate 5 and the convenient fixing member 7, when the partition sliding plate 5 slides downward, the vertical sliding push plate 72 contacts the L-shaped folding plate 76 and drives the L-shaped folding plate 76 to move downward. Through the pushing connecting plate 77 and the hinged fixing seat 78, the moving insertion rod 79 is driven to move out of the fixed slot 710, releasing the restriction of the moving insertion rod 79 on the filter plate member 8, facilitating the direct removal of the filter plate member 8. When the partition sliding plate 5 slides upward, the partition sliding plate 5 drives the vertical sliding push plate 72 to move upward through the connecting support plate 71. The vertical sliding push plate 72 is separated from the L-shaped folding plate 76. Under the elastic action of the return spring 75, the L-shaped folding plate 76 is driven to move upward. The L-shaped folding plate 76 drives the moving insertion rod 79 to extend into the fixed slot 710 through the pushing connecting plate 77 and the hinged fixing seat 78, realizing the limiting and fixing of the filter plate member 8 and ensuring the stability of the filter plate member 8.It is convenient to quickly install the filter plate 8.

The support rotating shaft 64 is rotatably connected to the communicating branch pipe 4 through a support plate. The end of the support rotating shaft 64 away from the drive worm gear 63 is fixedly connected to the drive gear 65. Both sides of the drive gear 65 are meshed with the L-shaped toothed plates 66. The two L-shaped toothed plates 66 are respectively slidably connected to the two communicating branch pipes 4. One ends of the two L-shaped toothed plates 66 are respectively fixedly connected to the two partition sliders 5. In actual use, in order to determine whether the filter plate 8 needs to be cleaned or replaced, the air flow passing through the filter plate 8 is monitored, and the clogging condition of the filter plate 8 is judged according to the air flow. This process is the prior art and will not be elaborated here. When the dust accumulates too much on the filter plate 8 and clogging occurs and needs to be cleaned and replaced, by starting the drive motor 61, the drive motor 61 drives the drive worm 62 to rotate, the drive worm 62 drives the drive worm gear 63 to rotate, the drive worm gear 63 drives the drive gear 65 to rotate through the support rotating shaft 64, and the drive gear 65 drives the L-shaped toothed plate 66 installed on the communicating branch pipe 4 where the filter plate 8 to be replaced is located, so that it slides downward, and then drives one partition slider 5 to move downward to close the air duct of the communicating branch pipe 4, and the other L-shaped toothed plate 66 slides upward to drive the partition slider 5 thereon to move upward, realizing the opening of the air duct of the other communicating branch pipe 4, and thus realizing the alternate use of the two communicating branch pipes 4.

A plurality of pushing connecting plates 77 are hinged to one end of the L-shaped folding plate 76 close to the filter plate member 8. One end of the pushing connecting plate 77 away from the L-shaped folding plate 76 is hinged with a hinged fixing seat 78.

[0036] The pre-wetting member 10 includes a liquid collecting box body 101, a liquid inlet elbow 102, a one-way liquid inlet valve 103, a liquid outlet connecting elbow 104, a one-way liquid outlet valve 105, a liquid storage box body 106, a liquid inlet connecting pipe 107, an atomizing nozzle 108, a fixing sliding rod 109, a square piston 1010, a supporting flat plate 1011 and a liquid distribution cross pipe 1012. The liquid storage box body 106 is fixedly installed inside the partition sliding plate 5. The upper end of the liquid storage box body 106 is communicated with a liquid inlet connecting pipe 107. The upper end of the liquid inlet connecting pipe 107 extends out of the partition sliding plate 5. The liquid collecting box body 101 is fixedly installed inside the partition sliding plate 5. The upper end of the liquid collecting box body 101 is communicated with a liquid inlet elbow 102. One end of the liquid inlet elbow 102 away from the liquid collecting box body 101 extends into the liquid storage box body 106. A one-way liquid inlet valve 103 is arranged on the liquid inlet elbow 102. The liquid collecting box body 101 is communicated with a liquid outlet connecting elbow 104. A one-way liquid outlet valve 105 is arranged on the liquid outlet connecting elbow 104. One end of the liquid outlet connecting elbow 104 away from the liquid collecting box body 101 extends out of the partition sliding plate 5 and is communicated with a liquid distribution cross pipe 1012. A plurality of atomizing nozzles 108 are arranged on the liquid distribution cross pipe 1012. One end of the supporting flat plate 1011 is fixedly connected with the partition sliding plate 5, and the other end of the supporting flat plate 1011 is fixedly connected with the liquid distribution cross pipe 1012. The fixing sliding rod 109 is fixedly installed at the inner bottom of the communicating branch pipe 4. The upper end of the fixing sliding rod 109 extends into the partition sliding plate 5 and the liquid collecting box body 101 in sequence. The upper end of the fixing sliding rod 109 is fixedly connected with a square piston 1010. The square piston 1010 is slidably arranged inside the liquid collecting box body 101.

[0037] During actual use, the negative pressure fan 11 is turned on to create a negative pressure environment. The dust generated during the grinding process enters the connecting branch pipe 4 through the suction connecting pipe 2 and the shunt connecting pipe 3. At this time, one connecting branch pipe 4 is in a working state, and the other connecting branch pipe 4 is in a closed state. The filter plate member 8 in the working connecting branch pipe 4 filters the dust. When the dust accumulates too much on the filter plate member 8 and causes blockage and needs to be cleaned and replaced, by starting the driving motor 61, the driving motor 61 drives the driving worm 62 to rotate. The driving worm 62 drives the driving worm gear 63 to rotate. The driving worm gear 63 drives the driving gear 65 to rotate through the support rotating shaft 64, and then drives the L-shaped toothed plate 66 on the connecting branch pipe 4 where the filter plate member 8 needs to be replaced, so that it slides downward. This action drives the partition sliding plate 5 connected thereto to move downward, thereby closing the air duct of this connecting branch pipe 4. At the same time, the other L-shaped toothed plate 66 slides upward, driving the partition sliding plate 5 thereon to move upward, and opening the air duct of the other connecting branch pipe 4. In this way, the alternative use of the two connecting branch pipes 4 is realized. When one connecting branch pipe 4 is in a working state, the other connecting branch pipe 4 is in a closed state, and it is possible to replace the filter plate member 8 on the closed connecting branch pipe 4 without shutting down the machine. When the partition sliding plate 5 slides downward, the square piston 1010 squeezes the water in the liquid collecting box body 101 through the liquid outlet connecting elbow 104. The water enters the liquid distribution cross pipe 1012 and finally sprays out from the atomizing nozzle 108. The sprayed water is used to moisten the filter plate member 8 to reduce the flying of dust when the filter plate member 8 is disassembled. At the same time, the connecting support plate 71 drives the vertical sliding push plate 72 to slide downward. The vertical sliding push plate 72 contacts the L-shaped folding plate 76 and drives the L-shaped folding plate 76 to move downward. The L-shaped folding plate 76 slides downward on the fixed sliding column 74 and squeezes the return spring 75. The L-shaped folding plate 76 moves downward, and drives the moving insertion rod 79 to move out of the fixed insertion slot 710 through the pushing connecting plate 77 and the hinged fixing seat 78, releasing the restriction of the moving insertion rod 79 on the filter plate member 8, facilitating the direct removal of the filter plate member 8, and improving the convenience; when the partition sliding plate 5 slides upward, a negative pressure is formed in the liquid collecting box body 101, and the water in the liquid storage box body 106 enters the liquid collecting box body 101 through the liquid inlet elbow 102. At the same time, the partition sliding plate 5 drives the vertical sliding push plate 72 to move upward through the connecting support plate 71. The vertical sliding push plate 72 separates from the L-shaped folding plate 76. Under the elastic action of the return spring 75, it drives the L-shaped folding plate 76 to move upward. The L-shaped folding plate 76 drives the moving insertion rod 79 to extend into the fixed insertion slot 710 through the pushing connecting plate 77 and the hinged fixing seat 78, realizing the limit fixation of the filter plate member 8, ensuring the stability of the filter plate member 8, and facilitating the rapid installation of the filter plate member 8.
