Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Such as Figures 1 to 8As shown in the figure, the utility model provides a production paint filtering device, which includes a filtering box 1. A flow guide plate 12 is fixedly connected to the inner wall of the filtering box 1. A stirring mechanism 4 is arranged on the outer wall of the flow guide plate 12. A discharge plate 5 is fixedly connected to the front outer wall of the filtering box 1. A motor 6 is fixedly connected to the rear outer wall of the filtering box 1. The output shaft of the motor 6 is fixedly connected with a main gear 7. A secondary gear 8 is meshed with the outer wall of the main gear 7. A rotating shaft 9 is fixedly connected to the outer wall of the main gear 7. An insertion block 11 is inserted into the inner wall of the rotating shaft 9. A filtering cylinder 3 is fixedly connected to the outer wall of the insertion block 11. An installation mechanism 2 is arranged on the outer wall of the filtering cylinder 3. The installation mechanism 2 includes a fixing block 201. A handle 203 is elastically connected to the inner wall of the fixing block 201 through a scroll spring 202. A fixing plate 204 is fixedly connected to the outer wall of the handle 203. A clamping block 205 is hinged to the outer wall of the fixing plate 204 through a connecting rod 207. A rotating block 206 is rotatably connected to the outer wall of the fixing block 201. A clamping groove 10 is opened on the front inner wall of the filtering box 1.

[0026] Adopting the above scheme: The whole device is inclined. The production paint to be filtered can be first poured into the stirring mechanism 4, and the impurities inside are further dispersed through stirring. Then, it flows on the flow guide plate 12 through the opening below the stirring box 401, and then flows on the filtering cylinder 3 through the flow guide plate 12 for filtering. Finally, the filtered production paint can flow out through the opening at the bottom of the filtering box 1 and the discharge plate 5; when the motor 6 is started, the output shaft of the motor 6 can drive the main gear 7 to rotate. Both the main gear 7 and the secondary gear 8 are rotatably connected to the inner wall of the filtering box 1. The main gear 7 can drive the rotating shaft 9, the insertion block 11 and the filtering cylinder 3 to rotate. Since the main gear 7 and the secondary gear 8 are meshed, the secondary gear 8 can be driven to rotate. The secondary gear 8 can drive the rotating rod 402 to rotate, and the impurities are dispersed through the stirring rod 403.

[0027] As Figures 2 to 6 As shown in the figure, the fixing block 201 is in contact with the front inner wall of the filtering box 1. The handle 203 is rotatably connected to the inner wall of the fixing block 201. The fixing plate 204 is rotatably connected to the inner wall of the fixing block 201; One end of the scroll spring 202 is fixedly connected to the outer wall of the handle 203, and the other end of the scroll spring 202 is fixedly connected to the inner wall of the fixing block 201; One end of the connecting rod 207 is hinged to the outer wall of the clamping block 205, and the other end of the connecting rod 207 is hinged to the outer wall of the fixing plate 204. The clamping block 205 is slidably connected to the inner wall of the fixing block 201, and the clamping block 205 is clamped with the clamping groove 10.

[0028] Adopting the above solution: The filter cartridge 3 can be conveniently and quickly disassembled and installed through the installation mechanism 2 for replacement or cleaning; when not affected by external forces, the scroll spring 202 and the handle 203 are in a static state, and the fixed plate 204, the connecting rod 207, and the clamping block 205 are also in a static state. In this state, the clamping block 205 is clamped with the clamping slots 10 opened on both inner walls of the filter box 1, so that the fixing block 201 can be fixed to the filter box 1; at this time, the insertion block 11 is inserted into the rotating shaft 9, and the inner wall of the rotating shaft 9 is provided with a slot adapted to the shape of the insertion block 11, as Figure 5 and Figure 6 shown. When the motor 6 drives the main gear 7 and the rotating shaft 9 to rotate, the insertion block 11 can be driven to rotate synchronously, so that the filter cartridge 3 rotates; and since the filter cartridge 3 is fixedly connected to the rotating block 206, and the rotating block 206 is rotatably connected to the outer wall of the fixing block 201, the filter cartridge 3 drives the rotating block 206 to rotate on the outer wall of the fixing block 201, thereby achieving the filtering effect.

[0029] When it is necessary to remove the filter cartridge 3, the handle 203 can be rotated to make the scroll spring 202 contract under force, and the fixed plate 204 rotates synchronously, driving the two connecting rods 207 to flip, so that the clamping block 205 moves. Since the clamping block 205 is slidably connected to the inner wall of the fixing block 201 and can only move horizontally, the two clamping blocks 205 can be driven to move towards the middle simultaneously during the rotation of the handle 203. When the clamping block 205 moves out of contact with the clamping slot 10, the limit of the fixing block 201 can be released. At this time, pulling the handle 203 to pull out the fixing block 201 can drive the rotating block 206, the filter cartridge 3, and the insertion block 11 to move outwards synchronously, so that the filter cartridge 3 can be conveniently and quickly taken out from the inside of the filter box 1; during installation, the handle 203 is also rotated to make the clamping block 205 move into the fixing block 201, then the insertion block 11 is aligned with the slot of the rotating shaft 9, and the filter cartridge 3 is inserted into the filter box 1. When the clamping block 205 moves to a position corresponding to the clamping slot 10, the handle 203 can be released. Under the elastic force of the scroll spring 202, the handle 203 and the fixed plate 204 rotate in the reverse direction and reset, driving the two clamping blocks 205 to move towards both sides and be clamped with the clamping slot 10, and the installation can be completed. There is no need to install and disassemble the filter cartridge 3 by operating bolts multiple times, which is more convenient and fast.

[0030] As Figure 7 and Figure 8 shown, the stirring mechanism 4 includes a stirring box 401. A rotating rod 402 is rotatably connected to the inner wall of the stirring box 401. An installation block 406 is fixedly connected to the outer wall of the rotating rod 402. A groove 409 is opened on the inner wall of the installation block 406. A partition plate 408 is elastically connected to the inner wall of the installation block 406 through a telescopic spring 407. A stirring rod 403 is clamped to the inner wall of the installation block 406. Two wedge blocks 405 are slidably connected to the inner wall of the stirring rod 403. The two wedge blocks 405 are elastically connected through a connecting spring 404.

[0031] Adopting the above solution: There is a certain distance between the mixing tank 401 and the deflector 12. When the secondary gear 8 rotates under the influence of the primary gear 7, it can drive the rotating rod 402 to rotate synchronously. The production paint is stirred by the stirring rod 403, and the impurities in it are dispersed, making the dispersion more uniform, reducing the accumulation of impurities, and improving the filtration efficiency. The production paint after stirring can flow out from the opening below the mixing tank 401 and flow through the deflector 12 to the filter cylinder 3 for filtration. When the impurities in the production paint are large and may cause damage to a certain set of stirring rods 403, the damaged stirring rod 403 can be replaced separately, without the need to replace the entire rotating rod 402. The split design saves more maintenance costs.

[0032] As Figure 7 and Figure 8 shown, the mixing tank 401 is fixedly connected to the outer wall of the top of the deflector 12. The rotating rod 402 is fixedly connected to the secondary gear 8. The two ends of the connecting spring 404 are respectively fixedly connected to the outer walls of the two sets of wedges 405. The wedges 405 are clamped with the grooves 409. One end of the telescopic spring 407 is fixedly connected to the outer wall of the partition plate 408, and the other end of the telescopic spring 407 is fixedly connected to the inner wall of the mounting block 406. The outer wall of the partition plate 408 is slidably connected to the inner wall of the mounting block 406. The outer wall of the partition plate 408 is in contact with the outer wall of the stirring rod 403.

[0033] Adopting the above solution: When installing the stirring rod 403, the lower part of the stirring rod 403 can be inserted into the mounting block 406. The arc surface of the wedge 405 moves into the inner wall of the stirring rod 403 under the extrusion of the outer wall of the mounting block 406, and the connecting spring 404 contracts under force. When the stirring rod 403 is inserted until it contacts the partition plate 408, the stirring rod 403 can be rotated until the positions of the wedges 405 and the grooves 409 correspond. At this time, the connecting spring 404 drives the two sets of wedges 405 to pop out due to the elastic force and engage with the grooves 409, so that the stirring rod 403 can be fixed. When disassembling the damaged stirring rod 403, the stirring rod 403 can be pressed downwards. The partition plate 408 moves downwards to squeeze the telescopic spring 407. At this time, the arc surface of the wedge 405 is subjected to the force of the inner wall of the groove 409, and the wedge 405 moves towards the middle and is always kept in the inner wall of the stirring rod 403 under the pressure of the inner wall of the mounting block 406. Then rotate the stirring rod 403 to stagger the vertical positions of the wedges 405 and the grooves 409, and the stirring rod 403 can be moved upwards to be taken out for replacement. Thus, a damaged stirring rod 403 can be replaced separately, and when maintaining, it is not necessary to remove the entire rotating rod 402 for replacement, saving costs.

[0034] The working principle and usage process of the present utility model:

[0035] The operator can pour the production paint to be filtered into the mixing tank 401, and then start the motor 6. The output shaft of the motor 6 drives the main gear 7 to rotate. Both the main gear 7 and the auxiliary gear 8 are rotatably connected to the inner wall of the filter tank 1. On the one hand, the main gear 7 drives the rotating shaft 9, the plug 11, and the filter cylinder 3 to rotate. On the other hand, since the main gear 7 meshes with the auxiliary gear 8, the auxiliary gear 8 is driven to rotate. The auxiliary gear 8 drives the rotating rod 402 to rotate, and the stirring rod 403 on the rotating rod 402 disperses the impurities in the paint, making the impurities more uniform to avoid accumulation affecting filtration. The stirred paint flows out from the opening at the bottom of the mixing tank 401, falls on the deflector 12, and then flows through the deflector 12 to the filter cylinder 3 for filtration. Finally, the filtered production paint flows out through the opening at the bottom of the filter tank 1 and the discharge plate 5.

[0036] Without being affected by external forces, the clamping block 205 is clamped with the clamping groove 10 opened on both inner walls of the filter tank 1 to fix the fixing block 201 and the filter tank 1, and the plug 11 is inserted into the rotating shaft 9. When the motor 6 drives the main gear 7 and the rotating shaft 9 to rotate, the plug 11 can be driven to rotate synchronously, so that the filter cylinder 3 rotates. Since the filter cylinder 3 is fixedly connected to the rotating block 206, and the rotating block 206 is rotatably connected to the outer wall of the fixing block 201, the filter cylinder 3 drives the rotating block 206 to rotate on the outer wall of the fixing block 201, thus achieving the filtering effect. Disassembly process: When the filter cylinder 3 is blocked after long-term use and needs to be removed for cleaning or replacement, the handle 203 can be rotated to make the scroll spring 202 contract under force. The fixing plate 204 rotates synchronously, driving the two connecting rods 207 to turn over, so that the clamping block 205 moves horizontally towards the middle. When the clamping block 205 moves to be out of contact with the clamping groove 10, the limit of the fixing block 201 can be released. At this time, pulling the handle 203 to pull out the fixing block 201 can drive the rotating block 206, the filter cylinder 3, and the plug 11 to move outwards synchronously, and the filter cylinder 3 can be conveniently and quickly taken out from the inside of the filter tank 1.

[0037] After the cleaning or replacement is completed and the filter cylinder 3 needs to be installed, the handle 203 is also rotated to move the clamping block 205 into the fixing block 201. Then, the plug 11 is aligned with the slot of the rotating shaft 9, and the filter cylinder 3 is inserted into the filter tank 1. When the installation mechanism 2 moves to the position where the clamping block 205 corresponds to the clamping groove 10, the handle 203 is released. Under the elastic force of the scroll spring 202, the handle 203 and the fixing plate 204 rotate reversely to reset, driving the two clamping blocks 205 to move towards both sides and be clamped with the clamping groove 10 to complete the installation. There is no need to install and disassemble by rotating bolts or other methods multiple times, which is more convenient and fast.

[0038] After the production paint is poured into the mixing tank 401, it directly contacts the mixing rod 403. After long-term use, a certain set of mixing rods 403 may be damaged due to the impact force of larger impurities. At this time, it can be replaced separately; when it is necessary to disassemble the damaged mixing rod 403, press the mixing rod 403 downward, and the partition plate 408 moves downward to squeeze the telescopic spring 407. At this time, the arc surface of the wedge block 405 moves toward the middle under the force of the inner wall of the groove 409 being squeezed, and is always kept in the inner wall of the mixing rod 403 under the pressure of the inner wall of the mounting block 406. Then rotate the mixing rod 403 to stagger the vertical position of the wedge block 405 and the groove 409, and the mixing rod 403 can be moved upward and taken out for replacement.

[0039] When installing the mixing rod 403, insert the lower part of the mixing rod 403 into the mounting block 406. The arc surface of the wedge block 405 moves to the inner wall of the mixing rod 403 under the extrusion of the outer wall of the mounting block 406, and the connecting spring 404 contracts under force. When the mixing rod 403 is inserted until it contacts the partition plate 408, rotate the mixing rod 403 until the wedge block 405 corresponds to the position of the groove 409. At this time, the connecting spring 404 drives the two wedge blocks 405 to pop out and engage with the groove 409 due to the elastic force, and the mixing rod 403 can be fixed. Thus, a set of damaged mixing rods 403 can be replaced separately, and it is not necessary to remove the entire rotating rod 402 for replacement during maintenance, saving costs.
