Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a cleaning device for purified terephthalic acid powder. Background Technology

[0002] Purified terephthalic acid powder, as an important organic chemical raw material, is widely used in many fields such as polyester fiber, film, and plastics. Its purity directly affects the quality of downstream products; therefore, the cleaning and purification process of purified terephthalic acid powder has extremely high requirements during production and processing.

[0003] Currently, existing purified terephthalic acid powder cleaning devices on the market have shortcomings in practical applications. For example, some cleaning devices only process the powder through simple rinsing, which is insufficient to remove impurities attached to the powder surface, resulting in poor cleaning effect and failing to meet the high-purity production requirements. At the same time, after cleaning, the solid-liquid separation process is often inefficient and incomplete, which not only affects subsequent drying and processing steps but also wastes resources. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to provide a purified terephthalic acid powder cleaning device.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-3As shown, this utility model provides a technical solution: a purified terephthalic acid powder cleaning device, including a base plate 1, columns 2 symmetrically fixedly installed on the top of the base plate 1, a fixing plate 3 fixedly installed on the top of the columns 2, a cleaning tank 4 fixedly installed inside the fixing plate 3, an inlet pipe 5 fixedly installed on the top of the cleaning tank 4, a feed pipe 6 fixedly installed on the top of the cleaning tank 4, a discharge pipe 7 fixedly installed on the bottom of the cleaning tank 4, an mounting plate 8 fixedly installed on the top of the fixing plate 3, a PLC controller 9 fixedly installed on the outside of the mounting plate 8, a solid-liquid separation mechanism 10 installed on the top of the base plate 1, the solid-liquid separation mechanism 10 including a frame 101, an inclined filter plate 102 fixedly installed inside the frame 101, a vibration motor 104 fixedly installed on the top of the frame 101, side plates 105 fixedly installed on both sides of the frame 101, and round rods 106 symmetrically slidably connected inside the side plates 105. A stop 107 is fixedly installed at the top of the round rod 106, and a support column 108 is fixedly installed at the bottom of the round rod 106. A spring 109 and a spring 1010 are fitted on the outer wall of the round rod 106. A flow guide shell 1011 is fixedly installed at the bottom of the frame 101, and a drain pipe 103 is fixedly installed at the bottom of the flow guide shell 1011. There are four sets of support columns 108, and the four sets of support columns 108 are fixedly connected to the base plate 1. One end of the spring 109 is fixedly connected to the support column 108, and the other end of the spring 109 is fixedly connected to the side plate 105. The flow guide shell 1011 is interconnected with the frame 101 and the drain pipe 103. The vibration motor 104 is electrically connected to the PLC controller 9. One end of the spring 1010 is fixedly connected to the side plate 105, and the other end of the spring 1010 is fixedly connected to the stop 107.

[0023] In this embodiment, regarding the situation mentioned in the background art where "the solid-liquid separation process is often inefficient and incomplete after cleaning," the solid-liquid separation mechanism 10 of this device uses a vibration motor 104 to drive the frame 101 to vibrate. This, combined with the inclined filter plate 102, spring 109, and spring 21010, enhances the vibration effect, causing the liquid in the mixture to quickly pass through the inclined filter plate 102. The powder then slides down the inclined filter plate 102 with the help of vibration, achieving efficient and thorough solid-liquid separation and avoiding the impact of separation problems on subsequent drying and processing steps.

[0024] Example 2: As Figure 4 As shown, a drive motor 11 is fixedly installed on the top of the cleaning tank 4, a shaft 12 is fixedly installed on the output end of the drive motor 11, a stirring rod 13 is evenly fixedly installed on the outer wall of the shaft 12, a stirring rod 14 is evenly fixedly installed on the outer wall of the shaft 12, a spiral conveying blade 15 is fixedly installed on the bottom outer wall of the shaft 12, the spiral conveying blade 15 is rotatably connected to the discharge pipe 7, and the drive motor 11 is electrically connected to the PLC controller 9.

[0025] In this embodiment, the drive motor 11 is started by the PLC controller 9, which drives the shaft 12 to rotate. The stirring rod 13 and stirring rod 14 on the outer wall of the shaft 12 rotate synchronously. During the rotation, the stirring rod 13 and stirring rod 14 can fully stir the powder and cleaning liquid in the cleaning tank 4, so that the powder and cleaning liquid can fully contact each other, thereby thoroughly cleaning off the impurities attached to the powder surface. When the spiral conveying blade 15 at the bottom of the shaft 12 rotates, it can smoothly push the mixture to the discharge pipe 7 for subsequent solid-liquid separation operation.

[0026] The working principle of this embodiment is as follows: In use, firstly, the operator puts the purified terephthalic acid powder to be cleaned into the cleaning tank 4 through the feed pipe 6 at the top of the cleaning tank 4, and at the same time injects an appropriate amount of cleaning liquid into the cleaning tank 4 through the liquid inlet pipe 5. Then, the drive motor 11 is started by the PLC controller 9. The drive motor 11 drives the shaft 12 to rotate. The stirring rod 13 and stirring rod 14 on the outer wall of the shaft 12 rotate synchronously. During the rotation, the stirring rod 13 and stirring rod 14 can fully stir the powder and cleaning liquid in the cleaning tank 4, so that the powder and cleaning liquid can fully contact each other, thereby thoroughly cleaning off the impurities attached to the powder surface. When the spiral conveying blade 15 at the bottom of the shaft 12 rotates, it can smoothly push the mixture to the discharge pipe 7 for subsequent solid-liquid separation operation. After cleaning, the mixture enters the frame 101 of the solid-liquid separation mechanism 10 through the discharge pipe 7. At this time, the PLC controller 9 starts the vibration motor 104, which drives the frame 101 to vibrate. The side plates 105 on both sides of the frame 101 slide up and down along the round rod 106. The springs 109 and 1010 sleeved on the outer wall of the round rod 106 extend and retract accordingly, further enhancing the vibration effect of the frame 101. Under the vibration of the frame 101, the liquid in the mixture flows through the inclined filter plate 102 into the guide shell 1011 below, and then is discharged through the drain pipe 103. The purified terephthalic acid powder is trapped on the inclined filter plate 102. Since the inclined filter plate 102 is inclined, the powder slides down along the inclined direction of the inclined filter plate 102 with the help of vibration, realizing efficient solid-liquid separation.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
