Abstract
Description
Technical Field
[0001] This invention relates to the technical field of filtration equipment, and in particular to a resin filter cartridge for coating production. Background Technology
[0002] In the paint production process, various liquid polymer compounds need to be added to the paint raw materials. These ingredients are usually supplied by ingredient manufacturers. After the ingredient manufacturers transport the paint ingredients to the paint production plant in tank trucks, to ensure the purity of the materials, they need to be filtered to remove impurities such as dust and rust mixed in with the ingredients in the tank trucks. Currently, filter elements are usually made of polymer resin materials. The mesh of the resin filter element is easily corroded and damaged after prolonged contact with the material, resulting in collapse and blockage, hindering the flow of the material and causing difficulties in the material transportation process. To solve this problem, the existing utility model patent with patent publication number CN215085430U discloses a security filter that facilitates filter element replacement. Specifically, a movable filter element is installed inside the filter body. The filter element can be pulled out through a fitting component in the top cover hole, thus completing a quick replacement. When the above-mentioned filter is applied to a tank truck, the process of discharging material from the tank truck needs to be stopped when the filter element is replaced or repaired. After the filter element is replaced, the process of discharging material from the tank truck is restarted. This process is cumbersome and makes it difficult to achieve continuous production. In addition, the filter needs to be completely removed from the tank truck's discharge device, which reduces the tank truck's conveying efficiency. Summary of the Invention
[0003] The technical problem this invention aims to solve is that the process of discharging coating liquid from tank trucks is affected by the process of replacing and repairing filter elements, resulting in reduced conveying efficiency.
[0004] The technical solution adopted by this invention to solve its technical problem is: a resin filter cartridge for paint production, comprising a receiving sleeve, a filter tube assembly installed in the receiving sleeve, and a conversion device installed at the end of the receiving sleeve. The receiving sleeve includes a receiving sleeve and a receiving cover fixedly installed at the end of the receiving sleeve. The receiving cover has a rotating hole and a travel groove arranged around the rotating hole. The filter tube assembly includes a filter tube cover installed in the receiving sleeve, filter covers installed at both ends of the filter tube cover, and a filter cartridge tube disposed in the filter tube cover. The filter cartridge tube is fixedly installed... At the end of the filter tube cover, the conversion device includes a rotating rod rotatably mounted on the two receiving covers, a connecting frame sleeved on the rotating rod, a stroke rod slidably inserted in the stroke groove, and a control plate fixedly connecting the rotating rod and the stroke rod. The rotating rod is rotatably inserted into the rotating hole, the connecting frame is fixed on the rotating rod, and sleeves are fixedly installed at both ends of the connecting frame. The sleeves are fixedly sleeved on the filter tube cover, and the control plate is fixedly mounted on the end of the rotating rod. The control plate can also be rotatably sleeved on the stroke rod.
[0005] Furthermore, a clamping nut is fitted onto the stroke rod, and the clamping nuts are located on both sides of the receiving cover. After the clamping nuts are tightened on the stroke rod, they can be pressed against the receiving cover. The stroke rod is fixed in position within the stroke groove by the restriction of the clamping nuts.
[0006] Furthermore, the rotating rod has a mounting groove, which is formed on the side wall along the axial direction of the rotating rod. A brake ring is also fitted on the rotating rod, and a positioning protrusion is provided on the inner side of the brake ring. The positioning protrusion and the mounting groove are in an interference fit. The brake ring positions the connecting frame on the rotating rod through the positioning protrusion.
[0007] Furthermore, the connecting frame is provided with a linkage protrusion, which is slidably inserted into the mounting groove, and the brake ring fixes the position of the connecting frame on the rotating rod.
[0008] Furthermore, a connecting rod is fixedly installed on the end of the rotating rod, and both ends of the connecting plate are sleeved onto the connecting rod and the stroke rod.
[0009] Furthermore, a clamping nut is fitted on both the connecting rod and the travel rod, and the clamping nut fixes the position of the control plate on the connecting rod and the travel rod.
[0010] Furthermore, the filter cover has a flow tube, which is connected to the filter tube cover and passes through the receiving cover.
[0011] Furthermore, one end of the filter element tube is fixedly connected to the inner wall of the filter tube cover, and the other end of the filter element tube is fitted with a positioning ring, which abuts against the inner wall of the filter tube cover.
[0012] Furthermore, the positioning ring has a flow groove, which is arranged along the circumference of the positioning ring and extends through the positioning ring.
[0013] Furthermore, a soft washer is fitted on the travel rod, and the control plate is mounted on the soft washer.
[0014] The beneficial effects of this invention are that when the filter element tube inside the receiving sleeve needs to be replaced or repaired, the movement of the stroke rod in the stroke groove controls the rotation of the rotating rod inside the receiving sleeve. During the rotation of the rotating rod, the rotating frame can be driven to rotate inside the receiving sleeve, thereby driving the sleeve and filter tube cover to rotate inside the receiving sleeve, realizing the exchange of positions between the filter tube cover and the filter element tube at both ends of the rotating frame. The filter cover and filter tube cover can be removed and installed through the receiving sleeve to complete the replacement of the filter element tube. That is, the process of replacing the filter element tube and filter tube cover is completed inside the receiving sleeve, without having to remove the receiving sleeve from the filter, realizing continuous production, saving filter replacement steps, and improving conveying efficiency.

Workers can open the access slots 111 by folding down the receiving cover 120, allowing them to maintain the equipment inside the receiving sleeve 10 through the openings of the access slots 111. The receiving cover 120 is fixedly sealed to the openings at both ends of the receiving sleeve 110. A rotating hole 121 is formed at the center of the receiving cover 120, and a travel groove 122 is formed on the receiving cover 120 with the rotating hole 121 as the center. Mounting holes 123 are also provided on both sides of the rotating hole 121 on the receiving cover 120.
[0026] The filter tube device 20 includes a filter tube cover 210 installed in a receiving sleeve 110, filter covers 220 installed at both ends of the filter tube cover 210, and a filter element tube 230 disposed in the filter tube cover 210.
[0027] There are multiple filter tube covers 210. In this embodiment, two filter tube covers 210 are preferred. The filter tube cover 210 has a cylindrical structure with open ends. The filter tube cover 210 is arranged along the axial direction of the receiving sleeve 110. The filter cover 220 has a bowl-shaped structure. The edge of the filter cover 220 is provided with a flange (not shown in the figure). The filter cover 220 is sealed to the port of the filter tube cover 210 through the flange. The edge of the filter cover 220 is also provided with a sealing flange 223. The sealing flange 223 fits against the inner wall of the filter tube cover 210. Under the restriction of the sealing flange 223, the gap between the filter cover 220 and the filter tube cover 210 is sealed, thereby ensuring that a sealed cavity is formed between the filter tube cover 210 and the filter cover 220. One of the filter tube covers 210 has a flow tube 221 fixedly installed on the filter caps 220 at both ends. The flow tube 221 corresponds to the mounting hole 123. The flow tube 221 extends through the mounting hole 123 to the outside of the receiving sleeve 110 and is connected to the discharge pipe of the tank truck. The other filter tube cover 210 has a sealing tube 222 fixedly installed on the filter caps 220 at both ends. The sealing tube 222 is fixedly inserted into the mounting hole 123. Under the sealing of the sealing tube 222, a sealed cavity structure is formed between the filter tube cover 210 and the filter cap 220 inside the receiving sleeve 110. The filter element tube 230 is fixedly installed in the filter tube cover 210. One end of the filter element tube 230 is fixedly connected to the inner wall of the filter tube cover 210, and the other end of the filter element tube 230 is fitted with a positioning ring 231. The inner wall of the positioning ring 231 is fixedly fitted onto the filter element tube 230, and the outer wall of the positioning ring 231 abuts against the inner wall of the filter tube cover 210. With the support of the positioning ring 231, the position of the filter element tube 230 in the filter tube cover 210 is fixed. A flow groove 232 is opened on the positioning ring 231. The flow groove 232 is arranged along the circumference of the positioning ring 231 and passes through the positioning ring 231. The material discharged from the tanker truck flows through the flow pipe 221 into the filter tube cover 210, and then first enters the filter element tube 230. After being filtered by the filter element tube 230, it is discharged into the cavity between the filter element tube 230 and the filter tube cover 210, and is discharged through the flow pipe 221 at the other end of the filter tube cover 210.
[0028] Preferably, a control valve 224 is also provided on one of the flow pipes 221. The control valve 224 is preferably a ball valve, which can control the connection between the tank truck and the filter cover 210.
[0029] The conversion device 40 includes a rotating rod 410 that is rotatably inserted in the rotating hole 121, a connecting frame 420 sleeved on the rotating rod 410, a stroke rod 430 that is slidably inserted in the stroke groove 122, and a control plate 440 that is fixedly connected to the rotating rod 410 and the stroke rod 430.
[0030] A mounting bearing 415 is fitted onto the rotating rod 410. The mounting bearing 415 is fixedly installed in the rotating hole 121. The rotating rod 410 can be positioned at the axial center position in the rotating hole 121 by the mounting bearing 415. Several mounting grooves 411 are opened on the rotating rod 410. The mounting grooves 411 are opened on the side wall along the axial direction of the rotating rod 410. A brake ring 412 is also fitted onto the rotating rod 410. A positioning protrusion 413 is protruding on the inner side of the brake ring 412. The positioning protrusion 413 corresponds to the mounting groove 411. The positioning protrusion 413 is inserted into the mounting groove 411 in an interference fit manner. The brake ring 412 is slidably fitted onto the rotating rod 410 by the positioning protrusion 413. The connecting frame 420 is sleeved on the rotating rod 410. The connecting frame 420 has a protruding linkage protrusion 422. The linkage protrusion 422 can be slidably inserted into the mounting groove 411. The connecting frame 420 can be slidably sleeved on the rotating rod 410 through the linkage protrusion 422. The two ends of the connecting frame 420 are also fixedly installed with sleeves 421. The sleeves 421 are also set corresponding to the receiving cover 120. The sleeves 421 are sleeved on the filter tube cover 210.
[0031] The stroke rod 430 is a screw rod that slidably passes through the stroke groove 122. Several clamping nuts 431 are fitted on the stroke rod 430, with two clamping nuts 431 located on both sides of the receiving cover 120. Tightening the two clamping nuts 431 restricts the position of the stroke rod 430 on the receiving cover 120. A soft washer 432 is also fitted on the stroke rod 430. A connecting rod 414 is fixedly installed at the end of the rotating rod 410. The control plate 440 has a long plate structure, with both ends of the control plate 440 fitted onto the stroke rod 430 and the connecting rod 414, respectively. One end of the control plate 440 rests on the soft washer 432, and the other end rests on the end of the rotating rod 410. A clamping nut 441 is fitted on both the stroke rod 430 and the connecting rod 414 to fix the position of the control plate 440 on the connecting rod 414 and the stroke rod 430. The control plate 440 and the rotating rod 410 are fixedly connected. In this embodiment, the control plate 440 is preferably fixed to the end face of the rotating rod 410 by clamping with a clamping nut 441 and then welding.
[0032] When using the aforementioned resin filter cartridge 100 for paint production, first connect the flow pipe 221 to the output pipe of the tank truck, start the output pipe to discharge the material in the tank truck into the filter tube cover 210. After the material is filtered by the filter element tube 230, it flows to the target container through the flow pipe 221 on the other side. When the filter element tube 230 needs to be replaced, first close the control valve 224, open the receiving cover 120 on the receiving sleeve 10, and disconnect the flange connection between the filter tube cover 210 and the filter cover 220 through the access slot 111. Control the stroke lever. 430 slides in the stroke groove 122. The stroke rod 430 drives the control plate 440 to rotate around the axis of the receiving sleeve 110. When the control plate 440 rotates, it drives the rotating rod 410 to rotate relative to the receiving sleeve 110. Thus, the connecting frame 420 and the sleeve 421 can be rotated through the mounting groove 411 and the linkage protrusion 422. The two filter tube covers 210 in the sleeve 421 exchange positions. Then the filter cover 220 and the filter tube cover 210 are sealed together. The control valve 224 is opened. While discharging the material, the other filter element tube 230 is replaced and repaired.
[0033] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
