Description

Technical Field

[0001] This utility model relates to the field of polyether ester defoamer production technology, specifically a high-efficiency separation device for polyether ester defoamer production. Background Technology

[0002] The separation unit used in the production of polyether defoamers primarily separates waste residue from the production process. During the production of polyether defoamers, after the raw materials undergo polymerization, neutralization, and decolorization steps, some solid impurities or waste residues that are insoluble in the product are generated. These waste residues need to be removed from the product through a separation unit to ensure the quality and purity of the polyether defoamer.

[0003] An existing high-efficiency separation device for the production of polyether ester defoamers typically uses a motor to drive the separation filter cartridge to rotate, utilizing the principle of centrifugal force to effectively separate solid particles suspended in the liquid from the liquid. However, because the connection between the separation filter cartridge and the motor output is relatively fixed, cleaning the solid particles inside the separation filter cartridge can only be done manually, which is time-consuming and inconvenient for timely removal of impurities inside the separation filter cartridge. Excessive accumulation of impurities will affect the separation efficiency. Therefore, it is necessary to propose a high-efficiency separation device for the production of polyether ester defoamers to solve the above problems. Summary of the Invention

[0008] To facilitate the scraping of impurities from the inner wall of the separation filter cartridge, the outer wall of the conical seat, which is preferably used in the production of polyether ester defoamer according to this utility model, abuts against the inner wall of the separation filter cartridge.

[0009] To facilitate the sliding of impurities along the inclined surface, the upper end of the separation tank of this utility model, which is a high-efficiency separation device for the production of polyether ester defoamer, is preferably set with an inclined surface, and the inclination angle is the same as the taper of the conical seat.

A scraper 14 is fixedly connected to the lower end of the auxiliary rod 8.

[0023] In this embodiment: During use, the electric actuator 10 drives the connecting rod 11 and the conical seat 12 to move downwards, so that the lower end of the conical seat 12 abuts against the bottom of the inner interior of the separation filter cartridge 13. Then, the defoamer to be separated is introduced into the interior of the separation filter cartridge 13 for centrifugal separation. After separation for a period of time, the addition of defoamer to the interior of the separation filter cartridge 13 is stopped, and the electric actuator 10 is started to drive the connecting rod 11 and the conical seat 12 to move upwards, so that the upper end of the conical seat 12 abuts against the lower end of the scraper 14. The motor 4 is started to drive the first gear 5 to rotate. When wheel 5 rotates, it drives the second gear 7, which meshes with it, to rotate. When the second gear 7 rotates, it drives the sleeve 6, auxiliary rod 8, and scraper 14 to rotate. The rotation of scraper 14 can scrape the impurities at the upper end of the conical seat 12 into the interior of the slag storage shell 2 for collection. Then, the electric push rod 10 is started again to drive the connecting rod 11 and the conical seat 12 to move downward, so that the lower end of the conical seat 12 abuts against the bottom of the interior of the separation filter cartridge 13. Defoamer is then injected into the interior of the separation filter cartridge 13 for separation. At this time, there are no impurities inside the separation filter cartridge 13, which is conducive to efficient separation.

[0024] As a technical optimization of this utility model, a second motor 15 is installed at the lower end of the separation tank 1, and the output end of the second motor 15 passes through the separation tank 1 and is fixedly connected to the separation filter cartridge 13.

[0025] In this embodiment, the separation filter cartridge 13 can be easily driven to rotate by the second motor 15.

[0026] As a technical optimization of this utility model, the outer wall of the conical seat 12 abuts against the inner wall of the separation filter cartridge 13.

[0027] In this embodiment, the outer wall of the conical seat 12 abuts against the inner wall of the separation filter cartridge 13, which facilitates the falling of impurities separated inside the separation filter cartridge 13 into the upper end of the conical seat 12, and the conical seat 12 can be used to easily scrape off the impurities on the inner wall of the separation filter cartridge 13.

[0028] As a technical optimization of this utility model, the upper end of the separation tank 1 is set with an inclined surface, and the inclination angle is the same as the taper of the conical seat 12.

[0029] In this embodiment, the upper end of the separator 1 is set with an inclined surface, which allows impurities to slide off the inclined surface easily.

[0030] As a technical optimization of this utility model, the lower end of the scraper 14 extends into the interior of the slag storage shell 2, and its outer wall abuts against the outer wall of the conical seat 12 and the separation tank 1.

[0031] In this embodiment, the lower end of the scraper 14 extends into the interior of the slag storage shell 2, and its outer wall abuts against the outer wall of the conical seat 12 and the separation tank 1. The scraper 14 can easily scrape off the impurities that have not slid off the outer wall of the conical seat 12 and the separation tank 1, and at the same time facilitates the movement of impurities inside the slag storage shell 2 to the discharge hopper 16 for discharge.

[0032] As a technical optimization of this utility model, a drain pipe is installed on the outer wall of the separator 1, and a discharge hopper 16 is connected to the lower end of the slag storage shell 2.

[0033] In this embodiment: the separated defoamer can be conveniently discharged through the drain pipe, and the impurities inside the slag storage shell 2 can be conveniently discharged through the discharge hopper 16.

[0034] Working principle: In use, firstly, start the electric actuator 10 to drive the connecting rod 11 and the conical seat 12 to move downwards, so that the lower end of the conical seat 12 abuts against the inner bottom of the separator filter cartridge 13. Then, introduce the defoamer to be separated into the interior of the separator filter cartridge 13. Start the second motor 15 to drive the separator filter cartridge 13 to rotate for centrifugal separation. During the separation process, impurities remain inside the separator filter cartridge 13, and the separated defoamer is discharged through the drain pipe. After a period of separation, stop adding defoamer into the separator filter cartridge 13, and start the electric actuator 10 to drive the connecting rod 11 and the conical seat 12 to move upwards, so that the upper end of the conical seat 12... When the scraper 14 comes into contact with the lower end, the motor 4 is started to drive the first gear 5 to rotate. When the first gear 5 rotates, it drives the second gear 7 that meshes with it to rotate. When the second gear 7 rotates, it drives the sleeve 6, the auxiliary rod 8 and the scraper 14 to rotate. By rotating the scraper 14, the impurities at the upper end of the conical seat 12 can be scraped off and collected inside the slag storage shell 2. Then, the electric push rod 10 is started again to drive the connecting rod 11 and the conical seat 12 to move downward, so that the lower end of the conical seat 12 comes into contact with the bottom end of the separation filter cartridge 13. Defoamer is then injected into the interior of the separation filter cartridge 13 for separation. At this time, there are no impurities inside the separation filter cartridge 13, which is conducive to efficient separation.
