[0002] Polyester catalyst preparation equipment typically refers to specialized equipment used for the catalysts required in the polyester production process. Polyester production, especially in the polycondensation reaction stage, often requires the use of catalysts to accelerate the reaction process, increase yield, and control product quality.

At the same time, the waste liquid generated during the cleaning process cannot be effectively filtered and reused, resulting in resource waste and environmental pollution.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0038] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0039] In summary, with the help of the above-mentioned technical solution of this utility model, during the preparation process, the staff opens the cover 206 through the latch 7, and then classifies and stores different types of polyester catalyst raw materials in the placement chamber one and placement chamber two separated by the partition plate 203. After placement, the cover 206 is closed and sealed by the latch 7. During the preparation process, according to the ratio set by the controller, two metering pumps 204 respectively draw polyester catalyst raw materials from placement chamber one and chamber two, and accurately deliver them to the preparation cylinder 1 through the conveying pipe 205.

[0040] After being conveyed into the preparation cylinder 1, the hollow motor 302 drives the hollow rod 303 to rotate, which in turn drives the preparation rods 304, which are evenly distributed on the surface, to fully stir and mix the raw materials.

[0041] The waste gas generated during the preparation process enters the purification box 10 through the exhaust pipe 9.

The semiconductor cooling chip 13 cools the waste gas. The adsorption pump 14 set in the purification box 10 facilitates the delivery of the purified and cooled waste gas to the hollow motor 302 for auxiliary cooling and heat dissipation.

[0042] After preparation, open control valve 401 and one of the control valves 403. After preparation, the product is discharged through discharge pipe 402 and transported to filter press for deep processing to remove unreacted raw materials or by-products and ensure the purity of the final catalyst product.

[0043] When cleaning is required after preparation, the cleaning solution in the auxiliary box 501 is pumped into the hollow rod 303 through the auxiliary pipe 504 via the outlet pipe 502 and the pump 503. Then, the hollow motor 302 drives the hollow rod 303 to rotate. The cleaning solution is evenly sprayed onto the inner wall of the preparation cylinder 1 through the auxiliary spray head 505 on the surface of the hollow rod 303 and the preparation rod 304 to achieve all-round cleaning. After cleaning, the control valve 1 401 and the other control valve 2 403 are opened to discharge the cleaning waste liquid through the discharge pipe 402 into the filter pipe 404 and deliver it to the filter box 405.

[0044] Then the waste liquid passes sequentially through the filter screen plate 406, ceramic filter element plate 407, glass fiber filter element plate 408, activated carbon mesh plate 409 and ion exchange mesh plate 410 in the filter box 405 to remove impurities and catalyst particles. After filtration, the control valve 3 412 is opened to transport the filtered waste liquid to the auxiliary box 501 for storage through the output pipe 411 for future use. The filter box 405 and the storage box 202 are opened and closed quickly through the sealing cover 6 and the latch 7, respectively, which facilitates the replacement of filter elements or the replenishment of raw materials.
