Description

Technical Field

[0001] The invention relates to the technical field of centrifugal separation, in particular to a centrifugal separation device for processing polyurethane resin. Background Art

[0002] Polyurethane resin is a commonly used polymer compound. In order to improve the quality of polyurethane resin solution during its production and processing, it is necessary to centrifuge the polyurethane resin solution and filter and separate the solid impurities contained in the polyurethane resin solution. Usually, the polyurethane resin solution is poured into a filter cartridge, and then the filter cartridge is rotated so that the polyurethane resin solution passes through the filter holes, while the solid impurities remain inside the filter cartridge, thereby achieving the centrifugal separation effect of the polyurethane resin solution. However, in the prior art, the size of the filter cartridge is fixed, so that the solution inside is not easy to contact the filter cartridge, and the contact surface with the filter cartridge is small, resulting in low filtration efficiency. At the same time, the rotation speed cannot be adjusted according to solutions of different concentrations, resulting in a large impact force of the solution on the filter cartridge when filtering a solution with a larger concentration, which is easy to damage it, and the feed speed is fixed, which is prone to pauses and oversupply problems during the production process.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. The present invention provides a centrifugal separation device for processing polyurethane resin, which drives a rotating frame to rotate through a feed pipe. At this time, the centrifugal force generated during the rotation drives multiple support rods and connecting rods to move outward, and at the same time drives the filter plate to rotate. At this time, the solution on the top of the rotating frame contacts the filter plate through centrifugal force and is filtered. The filter plate is set obliquely to increase the contact area between the solution and the filter plate, thereby improving the filtering efficiency.

[0016] 2. The present invention provides a centrifugal separation device for processing polyurethane resin, which can drive the sliding frame at the bottom to move along the slide rail when the support rod moves, and cooperate with the first gear through the second gear. At this time, the rotating rod drives the incomplete gear on the surface to rotate. When the support rod drives the sliding frame to move outward, the toothed section of the incomplete gear meshes with the first rack and drives it to move in the opposite direction, so that the support rod moves in the opposite direction and drives the filter plate to shrink. The shrinking filter plate can squeeze the internal solution so that it can be filtered more quickly, thereby improving the filtration efficiency. When the toothless section of the incomplete gear rotates to the first rack position, the support rod can continue to move outward by centrifugal force, so that the filter plate can be continuously squeezed and expanded. By continuously squeezing the internal solution, the solid and liquid can be quickly and thoroughly separated, thereby improving production efficiency.

[0017] 3. The present invention proposes a centrifugal separation device for processing polyurethane resin, in which the connecting rod will synchronously reciprocate during the reciprocating movement of the support rod, and the rotating rod can be driven to reciprocate through the connection of the positioning rod. The third gear on the top of the multiple rotating rods is in contact with the second rack, which can drive the rotating blades to rotate. When the solution is fully stirred, the gaps between the solutions are filled, and the solid particles are more evenly distributed in the medium, with larger intervals between each other, and the pores are wider, and the filtration speed is improved. At this time, the flow of the solution can be accelerated, the filtration efficiency can be improved, and the particles in the solution can be prevented from aggregating together, resulting in clogging of the filter holes of the filter plate, thereby preventing the fluid from passing through. This aggregation phenomenon can be eliminated by stirring, thereby maintaining the permeability of the medium and making the filtration speed faster.

[0018] 4. The present invention proposes a centrifugal separation device for processing polyurethane resin, in which a motor drives the fourth gear to rotate according to the concentration of the internal solution, thereby driving the connecting pipe to rotate through cooperation with the fifth gear, and the motor is an adjustable speed motor, which can adjust the rotation speed of the feed pipe, thereby adjusting the rotation speed of the rotating frame, and can effectively avoid the rotating speed of the rotating frame being too fast, and the high-concentration solution having a greater impact on the filter plate and causing damage to the filter plate. Therefore, the rotation speed of the rotating frame can be adjusted for different internal concentration solutions according to different production needs, thereby improving the stability and safety of the device during operation.

[0019] 5. The present invention proposes a centrifugal separation device for processing polyurethane resin, in which the support rod drives the support frame to move through the sliding frame at the bottom during the reciprocating movement of the support rod, and the support frame drives the discharge pipe to rise and fall through the push rod. At this time, the solution dropped to the bottom of the tank body can pass through the discharge hole on the discharge pipe. According to the different centrifugal forces applied to the support rod, the maximum displacement distance of the support rod is different. At this time, the rising height of the discharge pipe can be changed with the rotation speed of the rotating frame. The greater the rotation speed, the higher the rising height of the discharge pipe and the faster the discharge speed. By adjusting the size of the discharge opening, the material discharge flow rate can be accurately controlled. Accurate control of the discharge speed can avoid pauses and oversupply in the production process, thereby improving production efficiency and coping with the discharge speeds of solutions of different concentrations, making the production process more flexible and changeable.

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0031] like Figure 1-8 As shown, a centrifugal separation device for processing polyurethane resin includes a tank body 1, a centrifugal mechanism 2 is arranged inside the tank body 1, the centrifugal mechanism 2 includes a feed pipe 201, a feed hole 202 is opened on the outer surface of the feed pipe 201 near the top, a sewage hole 203 is opened on the outer surface of the feed pipe 201 near the bottom, a rotating frame 204 is fixedly connected to the outer surface of the feed pipe 201, a plurality of support rods 205 and connecting rods 206 are slidably connected to the outer surface of the rotating frame 204, filter plates 207 are rotatably connected between adjacent support rods 205 and connecting rods 206 through bearings, a plurality of positioning grooves 208 are opened on the lower surface of the rotating frame 204, a plurality of support rods 205 are slidably connected to the positioning grooves 208, and a plurality of filter plates 207 are slidably connected to the rotating frame 204.

[0032] The effect is that the solution enters the tank body 1 from the feed port on the feed pipe 201, and drives the rotating frame 204 to rotate through the feed pipe 201. At this time, the centrifugal force generated during the rotation drives multiple support rods 205 and connecting rods 206 to move outward, and at the same time drives the filter plate 207 to rotate. At this time, the solution on the top of the rotating frame 204 contacts the filter plate 207 through centrifugal force and is filtered, and is filtered through the filter plate 207. At this time, impurities in the solution remain inside the multiple filter plates 207.

[0033] like Figure 1-8 As shown, a reciprocating mechanism 3 is also provided inside the tank body 1, and the reciprocating mechanism 3 includes a slide rail 301, and the lower surfaces of multiple support rods 205 are rotatably connected to a sliding frame 302 through bearings, the sliding frame 302 is slidably connected to the slide rail 301, and the outer surface of the sliding frame 302 is fixedly connected to a first rack 303, and the lower surface of the feed pipe 201 is connected to a sewage pipe 304, and the outer surface of the sewage pipe 304 is fixedly connected to a first gear 305, and the lower surface of the rotating frame 204 is rotatably connected to a rotating rod 306 through a bearing, and the outer surface of the rotating rod 306 is fixedly connected to a second gear 307 and an incomplete gear 308, the second gear 307 is meshed with the first gear 305, and the incomplete gear 308 is meshed with the first rack 303, the lower surface of the rotating frame 204 is fixedly connected to a sliding rod 6, and the outer surface of the sliding frame 302 is fixedly connected to a slide plate 7, and a spring 8 is provided between the slide plate 7 and the sliding rod 6.

[0034] The effect is that when the support rod 205 moves, the sliding frame 302 at the bottom can be driven to move along the slide rail 301, and the second gear 307 cooperates with the first gear 305. At this time, the rotating rod 306 drives the incomplete gear 308 on the surface to rotate. When the support rod 205 drives the sliding frame 302 to move outward, the toothed section of the incomplete gear 308 engages with the first rack 303 and drives it to move in the opposite direction, so that the support rod 205 moves in the opposite direction and drives the filter plate 207 to shrink. The shrinking filter plate 207 can squeeze the internal solution. When the toothless section of the incomplete gear 308 rotates to the position of the first rack 303, the support rod 205 can continue to move outward through centrifugal force, so that the filter plate 207 can be continuously squeezed and expanded, thereby improving production efficiency.

[0035] like Figure 1-8As shown, a separation mechanism 4 is also provided inside the tank body 1, and the separation mechanism 4 includes a positioning rod 401, and the outer surfaces of multiple connecting rods 206 are rotatably connected to rotating rods 402 through bearings, and adjacent rotating rods 402 are rotatably connected to the positioning rod 401 through bearings, and the upper surface of the rotating frame 204 is fixedly connected to multiple second racks 403, and the upper surfaces of multiple rotating rods 402 are fixedly connected to third gears 404, and the third gears 404 are meshingly connected with the second racks 403. The outer surfaces of multiple rotating rods 402 are fixedly connected to rotating blades 405, and the upper surface of the rotating frame 204 is provided with multiple sliding holes, and the multiple rotating rods 402 and the supporting rods 205 are respectively slidably connected to the sliding holes. A motor 9 is installed on the surface of the tank body 1, and the output end of the motor 9 is fixedly connected to a vertical rod 10, and the outer surface of the vertical rod 10 is fixedly connected to a fourth gear 11, and the outer surface of the feeding pipe 201 is fixedly connected to a fifth gear 12, and the fourth gear 11 is meshingly connected with the fifth gear 12, and the vertical rod 10 is rotatably connected to the tank body 1 through a bearing.

[0036] The effect is that when the support rod 205 moves back and forth, the connecting rod 206 will follow the reciprocating movement, and the connection through the positioning rod 401 can drive the rotating rod 402 to move back and forth. The third gear 404 at the top of the multiple rotating rods 402 contacts the second rack 403, which can drive the rotating rod 402 to rotate, and the rotating rod 402 can drive the rotating blade 405 to rotate, which can accelerate the flow of the solution and improve the filtration efficiency.

[0037] like Figure 1-8 As shown, a discharging mechanism 5 is also provided inside the tank body 1, and the discharging mechanism 5 includes a discharging pipe 501, and the lower surfaces of multiple sliding frames 302 are fixedly connected with support frames 502, and multiple push rods 503 are rotatably connected between the discharging pipe 501 and the multiple support frames 502 through a rotating shaft. The outer surface of the discharging pipe 501 is provided with multiple discharging holes, and the lower surface of the rotating frame 204 is provided with a through hole 504. The discharging pipe 501 is slidably connected to the tank body 1 and the sewage pipe 304 respectively, and multiple slide rails 301 are fixedly connected to the rotating frame 204. The inner surface of the tank body 1 is fixedly connected to the limiting frame 13, and the rotation and sliding connection with the limiting frame 13 are connected. The feed pipe 201 is rotatably connected to the tank body 1 through a bearing, and the sewage pipe 304 is fixedly connected to the tank body 1.

[0038] The effect is that during the reciprocating movement of the support rod 205, the support rod 205 drives the support frame 502 to move through the sliding frame 302 at the bottom, and the support frame 502 drives the discharge pipe 501 to rise and fall through the push rod 503. At this time, the solution that falls to the bottom of the tank body 1 can pass through the discharge hole on the discharge pipe 501 and be discharged from the tank body 1 from the discharge pipe 501, thereby realizing precise control of the material discharge flow rate, and precise control of the discharge speed can avoid pauses and oversupply during the production process.

[0039] Working principle: the resin solution is injected from the feed pipe 201, and the solution enters the tank body 1 from the feed port on the feed pipe 201. The feed pipe 201 is a tube body with hollow ends and a solid middle section. The top and bottom hollow parts are not connected. When mixing, the motor 9 drives the fourth gear 11 to rotate, the fourth gear 11 drives the fifth gear 12 to rotate, and the fifth gear 12 drives the feed pipe 201 to rotate.

At this time, through the centrifugal force generated during the rotation, multiple support rods 205 and connecting rods 206 move outward, and at the same time drive the filter plate 207 to rotate and move outward. At this time, the solution on the top of the rotating frame 204 moves outward by centrifugal force and passes through the filter plate 207. Filtration, at this time, impurities in the solution remain inside the multiple filter plates 207, and a valve is provided inside the sewage pipe 304. The impurities remaining on the rotating frame 204 after filtration can be discharged through the sewage pipe 304. The filtered solution passes through the filter plates 207 and flows downward along the inner wall of the tank body 1, passes through the through hole 504 on the rotating frame 204, and moves to the bottom of the rotating frame 204. At the same time, when the support rod 205 moves, it can drive the sliding frame 302 at the bottom to move along the slide rail 301. The sliding frame 302 rotates, driving the rotating rod 306 to rotate, and the rotating rod 306 drives the second gear 307 to rotate. When the second gear 307 rotates, it contacts the first gear 305 on the sewage pipe 304. At this time, the second gear 307 can rotate on its own, the second gear 307 drives the rotating rod 306 to rotate on its own, and the rotating rod 306 drives the incomplete gear 308 on the surface to rotate on its own, and when the support rod 205 drives the sliding frame 302 to move outward, the toothed section of the incomplete gear 308 meshes with the first rack 303 and drives it to move in the opposite direction, so that the support rod 205 moves in the opposite direction and drives the filter plate 207 to shrink, and the shrinking filter plate 207 can squeeze the solution inside so that it can be filtered more quickly, and when the toothless section of the incomplete gear 308 rotates to the position of the first rack 303, the support rod 205 can continue to move outward through centrifugal force, so that the filter plate 207 can be continuously squeezed and expanded to accelerate the filtration, and at the same time When the support rod 205 moves back and forth, the connecting rod 206 will follow the reciprocating movement, and the connection through the positioning rod 401 can drive the rotating rod 402 to move back and forth. The third gear 404 on the top of the multiple rotating rods 402 contacts the second rack 403, which can drive the rotating rod 402 to rotate, and the rotating rod 402 can drive the rotating blade 405 to rotate. In the process of the reciprocating movement of the support rod 205, the support rod 205 drives the support frame 502 to move through the sliding frame 302 at the bottom, and the support frame 502 drives the discharge pipe 501 to rise and fall through the push rod 503. At this time, the solution that falls to the bottom of the tank body 1 can pass through the discharge hole on the discharge pipe 501 and be discharged from the tank body 1 from the discharge pipe 501.
