Description

Technical Field

[0001] The utility model relates to the technical field of polyol production, in particular to a polyether polymer polyol production device with a filtering effect. Background Technique

[0002] The appearance of polymer polyol is generally white or light milky yellow. Polymer polyol is a kind of polyol containing organic fillers, which can replace inorganic fillers. It can not only endow polyurethane foam with higher load-bearing capacity and good resilience performance, but also improve the cell structure and physical and mechanical properties of the foam. During the production of polymer polyol, there will be a phenomenon that raw materials are not completely reacted, or a certain amount of impurities are mixed in, which affects the quality of polymer polyol. Therefore, the polymer polyol stock solution needs to be filtered during the production process.

[0003] For example, a filtering device in the production of yellowing-resistant polymer polyol disclosed in a Chinese patent with the publication number of CN215538987U includes a storage bin and a reduction motor. One side of the bottom end of the storage bin is provided with a discharge pipe, and the top end of the storage bin is provided with a filtering bin. The filtering bin is communicated with the storage bin. One side of the upper end of the filtering bin is provided with a feed pipe, and the other side of the filtering bin is provided with a slag removal door; a turntable is rotatably installed inside the filtering bin, a shell is fixed on the turntable, and an opening is formed in the middle of the turntable. The opening is located inside the shell. A cavity is arranged in the middle of the shell, and the cavity is communicated with the opening. Filter meshes are installed on both sides of the shell. When this device filters, the filtrate flushes the filter mesh on the side far from the feed pipe, thereby reducing the adhesion of impurities and improving the filtering effect.

[0004] During the implementation of this application, the inventor found that at least the following problems exist in this technology: Although the above technical solution can reduce the adhesion of impurities to the filter mesh and improve the filtering effect, in actual use, since the polymer polyol is a viscous liquid with poor fluidity, and this device still filters vertically, the filtering effect is relatively low, affecting the processing and production efficiency of polyether polymer polyol. Therefore, it can be further improved. Content of the Utility Model

[0005] To solve the above-mentioned problems, the utility model provides the following technical solution: A polyether polymer polyol production device with a filtering effect includes a tank body. A top cover is arranged at the top of the tank body. One side of the top of the top cover is communicated with a feed pipe. The center of the bottom of the tank body is fixedly communicated with a discharge pipe. A valve is arranged outside the discharge pipe. A servo motor is fixedly installed at the center of the top of the top cover. A jitter filtering component is arranged inside the tank body, and the servo motor drives the jitter filtering component.

[0006] As an optimization, the jitter filtering component includes a circular ring arranged inside the tank body and a rotating ring rotatably connected inside the tank body, and the rotating ring is located above the circular ring. A filter screen is arranged inside the circular ring. Four fixing plates are fixedly installed in an array on the inner wall of the tank body and below the circular ring. An activity plate is slidably connected inside the fixing plate. A spring is fixedly installed at the bottom of the activity plate, and the top of the activity plate is fixedly installed on the bottom side of the circular ring. The activity plate will be jacked up by the elastic force of the spring itself, so as to elastically support the circular ring. The polyether polymer polyol processed inside can be filtered through the filter screen.

[0007] As an optimization, a bracket is fixedly installed at the top of the rotating ring, and a rotating shaft is fixedly installed at the center of the top of the bracket. The top of the rotating shaft is fixedly installed at the bottom end of the output shaft of the servo motor. By starting the servo motor, the rotating shaft will be driven to rotate, so the bracket and the rotating ring will be driven to rotate synchronously, and then the polyether polymer polyol inside will be stirred to improve production efficiency.

[0008] As an optimization, a plurality of embedding grooves are arranged in an array on the top side of the circular ring. Corresponding to the embedding grooves on the bottom side of the rotating ring, rolling balls are embedded, and the rolling balls are movably clamped in the embedding grooves. By the rotation of the rotating ring, the rolling balls will be driven to roll along the top side of the circular ring, and then the rolling balls will move in and out of the embedding grooves back and forth, so the circular ring will move up and down back and forth, and then the filtration of the viscous polyol downward can be accelerated.

[0009] As an optimization, a slideway is arranged on the top side of the circular ring, and the slideway communicates with a plurality of embedding grooves, and the rolling balls roll along the track of the slideway. By using the slideway as the movement track of the rolling balls, a guiding effect can be achieved, so that the rolling balls can accurately move in and out of the embedding grooves.

[0010] As an optimization, heating rods are inserted into the wall of the tank body, and a plurality of heating rods are arranged around the tank body in an array. The polyether polymer polyol inside can be uniformly heated through the plurality of heating rods to improve processing efficiency.

[0011] As an optimization, a lead wire is fixedly installed at the bottom of the heating rod, and the bottom of the lead wire is connected with a wire ring. The heating rods are connected in series through the wire ring and the lead wire, which is convenient to start the heating rods for heating.

[0012] The beneficial effects of the present utility model are:

[0013] For the polyether polymer polyol production equipment with a filtering effect, by starting the servo motor, the rotating shaft will be driven to rotate, so the rotating ring will be driven to rotate, making the rolling balls roll along the top side of the circular ring, and then the rolling balls will move in and out of the embedding grooves back and forth, so the circular ring will be extruded. Since the activity plate is jacked up by the elastic force of the spring itself to elastically support the circular ring, the circular ring will move up and down back and forth, thereby accelerating the filtration efficiency of the viscous polyol.

[0021] Please refer to Figure 1 , a polyether polymer polyol production device with a filtering effect, including a tank body 1, a top cover 2 is arranged at the top of the tank body 1, a feed pipe 3 is communicated with one side of the top of the top cover 2, a discharge pipe 4 is fixedly communicated with the center of the bottom of the tank body 1, a valve 5 is arranged outside the discharge pipe 4, a servo motor 6 is fixedly installed at the center of the top of the top cover 2, a jitter filtering assembly 7 is arranged inside the tank body 1, and the servo motor 6 drives the jitter filtering assembly 7.

[0022] Please refer to Figures 2-3, the jitter filtering component 7 includes a circular ring 8 arranged inside the tank body 1 and a rotating ring 9 rotatably connected inside the tank body 1, and the rotating ring 9 is located above the circular ring 8. A filter screen 10 is arranged inside the circular ring 8. Four fixing plates 11 are fixedly installed in an array on the inner wall of the tank body 1 and below the circular ring 8. An activity plate 12 is slidably connected inside the fixing plate 11. A spring 13 is fixedly installed at the bottom of the activity plate 12, and the top of the activity plate 12 is fixedly installed on the bottom side of the circular ring 8. The activity plate 12 will be pushed up by the elastic force of the spring 13 itself, and then the circular ring 8 can be elastically supported. The polyether polymer polyol processed inside can be filtered through the filter screen 10;

[0023] Please refer to Figures 2-3 , a support 14 is fixedly installed at the top of the rotating ring 9. A rotating shaft 15 is fixedly installed at the center of the top of the support 14, and the top of the rotating shaft 15 is fixedly installed at the bottom end of the output shaft of the servo motor 6. By starting the servo motor 6, the rotating shaft 15 will be driven to rotate, so the support 14 and the rotating ring 9 will be driven to rotate synchronously, and then the polyether polymer polyol inside will be stirred to improve production efficiency;

[0024] Please refer to Figures 2-3 , a number of embedding grooves 16 are arranged in an array on the top side of the circular ring 8. A ball 17 is correspondingly embedded in the embedding groove 16 on the bottom side of the rotating ring 9, and the ball 17 is movably clamped in the embedding groove 16. By the rotation of the rotating ring 9, the ball 17 will be driven to roll along the top side of the circular ring 8, and then the ball 17 will move in and out of the embedding groove 16 back and forth, so the circular ring 8 will shake up and down, and then the thick polyol can be filtered downward more quickly;

[0025] Please refer to Figures 2-3 , a slideway 18 is arranged on the top side of the circular ring 8, and the slideway 18 communicates with a number of embedding grooves 16, and the ball 17 rolls along the track of the slideway 18. By using the slideway 18 as the movement track of the ball 17, a guiding effect can be achieved, so that the ball 17 can accurately move in and out of the embedding groove 16.

[0026] Please refer to Figure 4 , a heating rod 19 is inserted into the wall of the tank body 1, and a number of heating rods 19 are arranged around the tank body 1 in an array. The polyether polymer polyol inside can be uniformly heated through the number of heating rods 19 to improve the processing efficiency;

[0027] Please refer to Figure 4 , a lead wire 20 is fixedly installed at the bottom of the heating rod 19, and the bottom of the lead wire 20 is connected to a wire loop 21. The heating rods 19 are connected in series through the wire loop 21 and the lead wire 20, which is convenient to start the heating rods 19 for heating.

[0028] In use, first, raw materials are added into the tank body 1 through the feed pipe 3. Then, by starting the servo motor 6, the rotating shaft 15 will be driven to rotate, which will further drive the support 14 to rotate for stirring. At the same time, the rotating ring 9 will be driven to rotate, causing the ball 17 to roll along the top side of the ring 8. As a result, the ball 17 will move back and forth in and out of the slot 16, so the ring 8 will be squeezed. Since the spring 13 pushes up the movable plate 12 by its own elastic force to elastically support the ring 8, the ring 8 will vibrate up and down, which can accelerate the downward filtration of the viscous polyol. Finally, by opening the valve 5, the material can be discharged outward through the discharge pipe 4.

[0029] In summary, for the polyether polymer polyol production equipment with a filtering effect, by starting the servo motor 6, the rotating shaft 15 will be driven to rotate, which will drive the rotating ring 9 to rotate, causing the ball 17 to roll along the top side of the ring 8. As a result, the ball 17 will move back and forth in and out of the slot 16, so the ring 8 will be squeezed. Since the spring 13 pushes up the movable plate 12 by its own elastic force to elastically support the ring 8, the ring 8 will vibrate up and down, thereby accelerating the filtration efficiency of the viscous polyol.
