Description

A centrifugal separation device for processing polyurethane resin

Technical Field

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

Background Art

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. For this reason, we propose a centrifugal separation device for polyurethane resin processing.

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

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.

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.

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.

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.

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.

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.

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.

As shown in Figures 1-8, 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 to 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.
