Description

Technical Field

[0001] This utility model relates to the technical field of road surface crack detection devices, and in particular to a collection device for esterified water synthesized from polyester resin. Background Technology

[0002] Polyester resins are typically synthesized from polybasic acids and polyols through an esterification reaction. During the esterification reaction, the carboxyl group (-COOH) in the acid reacts with the hydroxyl group (-OH) in the alcohol to produce ester (-COO-) and water. A large amount of esterification water is generated during polyester resin synthesis. If this esterification water is not collected and treated effectively and in a timely manner, it will not only affect the production environment but may also corrode equipment. Esterification is a reversible reaction. To propel the reaction towards the formation of polyester resin, the water generated needs to be continuously removed. According to the principle of chemical equilibrium, as water, one of the products, is continuously removed, the reaction equilibrium shifts towards the forward reaction, thus promoting the formation of more polyester resin. If the esterification water is not removed in time, the reaction will reach a certain equilibrium state, hindering further synthesis of polyester resin. Existing systems connect a drain pipe to the bottom of the ester resin synthesis reactor for drainage. However, during drainage, there is a lack of a structure to filter the polyester resin components, resulting in some polyester resin components being discharged along with the esterification water. Furthermore, the polyester resin components in the esterification water are easily adsorbed onto the inner wall of the water collection tank, making cleaning of the tank inconvenient and hindering its use.

[0028] See Figure 1 and Figure 4 As shown;

[0029] This utility model discloses a collection device for esterified water from polyester resin synthesis. A drain pipe 120 is fixedly connected to the center of the bottom of a conical base 110. The drain pipe 120 is used to drain water from the conical base 110. A valve 121 is fixedly installed on the outer wall of the drain pipe 120 to control the flow of the drain pipe. A top cover 200 is inserted and connected to the top of the water collection tank 100. The top cover 200 is used to install a servo motor 240 and to cover the top of the water collection tank 100. A limit ring 210 is provided on the bottom outer wall of the top cover 200. The top cover 200 has a limiting function.

The servo motor 240 is used to drive the drive shaft 230 and the scraper frame 231 to rotate, so that the scraper frame 231 can easily clean the impurities adsorbed on the inner wall of the water collection tank 100. The output shaft of the servo motor 240 is fixedly connected to the drive shaft 230. The scraper frame 231 is fixedly installed on the outer wall of the drive shaft 231. The inner wall of the scraper frame 231 is welded with reinforcing ribs 241. The top inner wall of the top of the top cover 200 has a vent hole 220, which is used to maintain a constant air pressure inside the water collection tank 100.

[0030] Example 3:

[0031] See Figures 1-3 As shown;

[0032] This utility model discloses a collection device for esterified water generated during polyester resin synthesis. The filter includes a housing 330 for mounting a filter element 331. The housing 330 is connected to the top of a first conduit 320 via a flange. The filter element 331 is inserted into the inner wall of the housing 330. The filter element 331 filters and intercepts the polyester resin raw materials, thus facilitating the filtration of esterified water generated during the polyester resin synthesis process. The top of the housing 330 is connected to a filter disc 340 via a flange. A filter screen 341 is installed on the inner wall of the filter disc 340 for filtration. The filter disc 340 is connected to the bottom of the polyester resin synthesis reactor. The output end of a self-priming pump 300 is connected to the inner wall of a water collection tank 100 via a second conduit 310. The self-priming pump 300 is used to transport water from the polyester resin synthesis reactor to the water collection tank 100 for collection under negative pressure.

[0033] The specific usage process of this utility model is as follows: When used by those skilled in the art, the housing 330 is connected to the top of the first conduit 320 via a flange, then the filter element 331 is installed inside the housing 330, then the filter disc 340 is fixedly connected to the top of the housing 330 via a flange, then the filter screen 341 is fixedly installed inside the filter disc 340 with bolts, and the top of the filter disc 340 is fixedly connected to the bottom inner wall of the polyester resin synthesis reactor with bolts. This allows the self-priming pump 300 to generate negative pressure inside the first conduit 320 after esterification water is produced during the polyester resin synthesis process. This allows the first conduit 320 to promptly draw the water produced during the polyester resin synthesis process into its interior. The water is then discharged into the water collection tank 100 through the second conduit 310. Under the action of gravity, the water flows to the conical bottom 110 for collection. When draining the water inside the conical bottom 110, the valve 121 on the outer wall of the drain pipe 120 at the bottom is opened, so that the water in the water collection tank 100 is discharged through the drain pipe 120 under the action of gravity. The water collection tank 100 contains unfiltered polyester resin that is adsorbed on the inner wall of the water collection tank 100. By turning on the servo motor 240 to drive the drive shaft 230 to rotate, the drive shaft 230 can drive the scraper frame 231 and the reinforcing rib 232 to scrape the inner wall of the water collection tank 100, thereby facilitating the cleaning of the surface of the water collection tank 100. The outer wall of the scraper frame 231 is made of soft silicone.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
