[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0037] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale.

[0038] Example 1

[0039] Reference Figures 1 to 6 , which is the first embodiment of the present invention, provides a high-efficiency filtration titanium dioxide oil fume purification method, which realizes the effects of enhanced purification materials, auxiliary disassembly and assembly, scraper scraping and cleaning liquid spraying through a high-efficiency filtration titanium dioxide oil fume purification plate and its operation method.

[0040] When the cylinder assembly 102 is working, the fixed frame 302 and the oil fume purification plate body 303 are disassembled and assembled. When the control cylinder 102a is started, the first limiting rod 301 fixed to it is driven to move, and then the fixed frame 302 and the oil fume purification plate body 303 are moved out through the second limiting rod 304, avoiding the inconvenience and potential safety risks of manual operation. At the same time, the scraper assembly 103 is used to assist in scraping when the fixed frame 302 moves, reducing manual operation.

[0041] When the fixed frame 302 moves, the spray mechanism 400 is activated to spray the cleaning agent for auxiliary cleaning. When the fixed frame 302 moves, the control rod 404c on one side rotates through the rotating shaft, and then the plug plate 404b is controlled to open the connecting pipe 402 so that the connected spray nozzle 403 starts spraying, thereby preventing some residual impurities that are difficult to completely remove with only a scraper;

[0042] Titanium dioxide and nickel are added to the material of the oil fume purification plate body 303 for catalytic purification, so that the oil fume particles collide and change in charge, thereby adsorbing the oil fume in the plate and recovering it downstream.

[0043] Example 2

[0044] Reference Figures 2-4 , which is the second embodiment of the present invention, provides a sliding mechanism 200, through which auxiliary disassembly and assembly and cleaning liquid spraying are achieved.

[0045] The sliding mechanism 200 includes a sliding plate 201. Four sliding plates 201 are provided and are symmetrical on the left and right sides. The left side of the sliding plate 201 is slidingly connected to the right side of the fixed plate 101. Sliding grooves 202 are provided on the left and right sides of the fixed plate 101 and at positions corresponding to the sliding plates 201. A fixing mechanism 300 is provided at the front end of the sliding plate 201, and a spraying mechanism 400 is provided on the left and right sides of the fixed plate 101.

[0046] The fixing mechanism 300 includes a first limiting rod 301, the back end of the first limiting rod 301 is fixedly connected to the front end of the sliding plate 201, the inner side of the first limiting rod 301 is slidably connected to a fixing frame 302, the inner side of the fixing frame 302 is provided with an oil fume purification plate body 303, the top and bottom of the fixing frame 302 are fixedly connected to a second limiting rod 304, and the top of the second limiting rod 304 is slidably connected to the bottom of the support plate 104 and the connecting plate 105.

[0047] The spraying mechanism 400 includes a liquid storage box 401, the top and bottom of the right side of the liquid storage box 401 are fixedly connected to a connecting pipe 402, the front end of the connecting pipe 402 is fixedly connected to a spray nozzle 403, and the top and bottom of the liquid storage box 401 are movably connected to a control part 404 through a rotating shaft.

[0048] The control component 404 includes a rotating block 404a, the bottom of the rotating block 404a and the top of the liquid storage box 401 are movably connected through a rotating shaft, the back end of the rotating block 404a is fixedly connected to the plug plate 404b, the book search plug plate 404b passes through the inner cavity of the connecting tube 402, and the front end of the rotating block 404a is fixedly connected to the control rod 404c, and the front end of the control rod 404c extends to the right side of the fixed frame 302.

[0049] Specifically, a sliding groove 202 is provided at a corresponding position of the fixed plate 101 so that the sliding plate 201 can slide smoothly in the sliding groove 202 , thereby ensuring the stability of the overall structure of the device during operation and preventing shaking or deviation.

[0050] Specifically, it ensures that the position of the fixing frame 302 is accurate during installation and subsequent use. At the same time, the first limiting rod 301 has a lateral limiting effect on the fixing frame 302 to prevent it from unnecessary deviation or shaking in the horizontal direction.

[0051] Specifically, when cleaning the oil fume purification plate or other related components, the cleaning liquid can be evenly distributed on the surface to be cleaned, ensuring that all parts can be effectively cleaned, improving cleaning efficiency and reducing cleaning dead corners.

[0052] Specifically, the control of the spraying mechanism 400 is achieved, which avoids the need for the operator to go deep into the equipment to operate control components such as the valve on the liquid storage box 401 or the connecting pipe 402, thereby greatly improving the convenience and safety of operation.

[0053] Furthermore, the cylinder assembly 102 is started, and the control cylinder 102a in the cylinder assembly 102 works to push the rectangular plate 102b at the front end, and the rectangular plate 102b drives the long plates 102c at the top and bottom, and the long plate 102c then makes the sliding plate 201 on the right side slide in the sliding groove 202 on the right side of the fixed plate 101, and then the fixed frame 302 and the oil fume purification plate body 303 can be moved out from one side through the second limiting rod 304. When the cylinder assembly 102 is working, the fixed frame 302 and the oil fume purification plate body 303 are disassembled and assembled to avoid the inconvenience of manual operation and potential safety risks.

[0054] Furthermore, when the fixed frame 302 moves, the control member 404 is operated. When the fixed frame 302 moves, it contacts the control rod 404c, causing the control rod 404c to rotate via the rotating shaft, which in turn drives the rotating block 404a to rotate, causing the insert plate 404b to move within the inner cavity of the connecting tube 402, thereby opening the connecting tube 402 and connecting it to the front spray nozzle 403 to spray the cleaning agent. The movement of the fixed frame 302 activates the spray mechanism 400 to spray the cleaning agent for auxiliary cleaning, avoiding residual impurities that are difficult to completely remove with a scraper alone.

[0055] Example 3

[0056] Reference Figures 1 to 6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: this embodiment provides a titanium dioxide oil fume purification plate with high filtration efficiency.

[0057] When oil smoke passes through, the oil smoke purification plate body 303 starts to work. Since it is set to a front interception mode and the material adds titanium dioxide and nickel for catalytic purification, the oil smoke particles will collide when passing through the purification plate body, and the charge will change, so that the oil smoke is adsorbed in the plate and recovered downstream. The oil separation and recovery rate can reach 96%, effectively purifying the oil smoke. Specific standard parameters: thickness is 10 / 15mm, length and width specifications are 500*500mm, hole density is 18 / 20ppi aperture, water pressure resistance is 3~6Mpa98%, through-hole rate is 92%~95%, porosity is 92%~95%, ventilation flow area ≥95%, oil smoke interception rate is 96%, corrosion resistance is 72 hours, melting point is 1450℃, AI grade non-combustible.

[0058] When maintenance is required on the fixed frame 302 and the oil fume purification plate body 303, the cylinder assembly 102 is started, and the control cylinder 102a in the cylinder assembly 102 works to push the rectangular plate 102b at the front end, and the rectangular plate 102b drives the long plates 102c at the top and bottom, and the long plates 102c then make the sliding plate 201 on the right side slide in the sliding groove 202 on the right side of the fixed plate 101, and then the fixed frame 302 and the oil fume purification plate body 303 can be moved out from one side through the second limiting rod 304. When the cylinder assembly 102 is working, the fixed frame 302 and the oil fume purification plate body 303 are disassembled and assembled, avoiding the inconvenience of manual operation and potential safety risks.

[0059] As the fixed frame 302 moves, the scraper assembly 103 begins to function. The scraper plate 103a in the scraper assembly 103 has its right side fixedly connected to the right side of the inner wall of the fixed plate 101, and its front end in contact with the back of the fixed frame 302. As the fixed frame 302 moves, the scraper plate 103a assists in scraping the surfaces of the fixed frame 302 and the oil fume purification plate body 303, reducing manual labor and removing impurities that may be attached to the surface.

[0060] When fixed frame 302 moves, control member 404 is operated. This movement of fixed frame 302 contacts control lever 404c, causing it to rotate via the shaft. This in turn drives rotating block 404a, causing insert plate 404b to move within the inner cavity of connecting tube 402, thereby opening connecting tube 402 and connecting it to spray nozzle 403 at the front end to spray cleaning agent. The movement of fixed frame 302 activates spray mechanism 400, which sprays cleaning agent for auxiliary cleaning, preventing residual impurities that are difficult to completely remove with a scraper alone.

[0061] In summary, when the cylinder assembly 102 is working, the fixed frame 302 is disassembled and assembled, and when the fixed frame 302 moves, the scraper assembly 103 is used for auxiliary scraping. When the fixed frame 302 moves, the spraying mechanism 400 is started to spray the cleaning agent for auxiliary cleaning, and titanium dioxide and nickel are added to the material of the oil fume purification plate body 303 for catalytic purification.
