Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for acetate production. Background Technology

[0002] Acetates are a general term for compounds formed by the esterification reaction of acetic acid and alcohols. They can be divided into food additives (such as starch acetate) and industrial solvents (such as ethyl acetate and butyl acetate) according to different substituents. In the industrial production of acetates (such as ethyl acetate and butyl acetate), wastewater mainly comes from washing water after esterification reaction, equipment cleaning water and unreacted raw material residue.

[0003] Currently, wastewater treatment generally involves adding acid-base regulators, flocculants, coagulants, and oxidants to purify the wastewater. After being treated by flocculants and coagulants, the wastewater produces a large amount of flocculent flocculation. This flocculent flocculation settles and adheres to the bottom of the treatment equipment, easily causing blockage and accumulation at the outlet. In addition, before adding chemicals to treat the wastewater, preliminary filtration is required to prevent a large number of large particles from directly entering the treatment equipment.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution for a wastewater treatment device for acetate production: It includes a shell 100, a hemispherical bottom frame 110 fixedly installed at the lower end of the outer wall of the shell 100, connecting pipes 120 circumferentially fixedly connected to the upper end of the outer wall of the shell 100, a filter frame 600 fixedly installed at the upper end of the outer wall of the connecting pipe 120, an inlet pipe 610 fixedly connected to the upper side of the outer wall of the filter frame 600, a filter screen 640 detachably connected inside the filter frame 600, a discharge pipe 130 fixedly connected to the lower end of the outer wall of the shell 100, a valve 140 fixedly installed on the discharge pipe 130, and a valve 140 fixedly installed on the inner wall of the shell 100. A rotating rod 200 is rotatably connected to the end of the filter, and a stirring rod 210 is fixedly installed on the outer wall of the rotating rod 200. Wastewater and treatment agents generated during the production of acetate are introduced into the filter frame 600 through the inlet pipe 610. The wastewater entering the filter frame 600 is initially filtered through the filter screen 640 in the filter frame 600, and large particulate impurities are collected and removed. The filtered wastewater enters the shell 100 through the connecting pipe 120. The rotation of the rotating rod 200 can stir the wastewater in the shell 100, allowing it to react fully with the treatment agents and accelerating the treatment rate of the treatment agents.

[0018] An annular sliding frame 300 is fixedly installed on the lower part of the inner wall of the housing 100. A sliding block 320 is slidably connected inside the annular sliding frame 300. A connecting plate 310 is fixedly connected between the sliding block 320 and the rotating rod 200. A connecting rod 330 is fixedly installed on the lower end of the outer wall of the connecting plate 310. An arc-shaped scraper 340 that fits into the inner wall of the hemispherical bottom frame 110 is fixedly connected to the lower end of the outer wall of the connecting rod 330. When the rotating rod 200 rotates, it will drive the connecting plate 310 to rotate, allowing the sliding block 320 to slide inside the annular sliding frame 300, thereby causing the connecting rod 330 and the arc-shaped scraper 340 to rotate. The rotation of the arc-shaped scraper 340 can clean the inner wall of the hemispherical bottom frame 110, preventing the flocculent material generated during the treatment of sewage from settling and sticking to the inner wall of the hemispherical bottom frame 110.

[0019] A motor frame 400 is fixedly connected to the upper side of the outer wall of the housing 100. A motor 410 is fixedly installed inside the motor frame 400. The output end of the motor 410 passes through the housing 100 and is fixedly connected to the rotating rod 200. The rotating rod 200 is rotated by starting the motor 410. A spiral stirring blade 500 is fixedly connected to the lower end of the side wall of the rotating rod 200. When the rotating rod 200 rotates, it will drive the spiral stirring blade 500 to rotate, which will agitate the discharge pipe 130 and prevent excessive accumulation of flocculent material in the discharge pipe 130, thus preventing blockage.

[0020] like Figure 1-3 and Figure 5 As shown, an installation port 620 is fixedly installed on the front end of the outer wall of the filter frame 600. A sliding plate 630 is inserted into the installation port 620, and a filter screen 640 is installed inside the sliding plate 630. A fixing plate 650 is fixedly installed on the front end of the outer wall of the sliding plate 630. A locking screw 660 is threadedly connected between the fixing plate 650 and the installation port 620. A rubber sealing ring 670 is fixedly connected to the rear end of the outer wall of the fixing plate 650. Personnel can pull the sliding plate 630 out of the installation port 620 by unscrewing the locking screw 660, thereby facilitating the removal of large particulate impurities intercepted and collected by the filter screen 640 and the cleaning and replacement of the filter screen 640. An observation window 700 is fixedly installed on the front side of the outer wall of the housing 100, allowing personnel to easily observe the sewage treatment status inside the housing 100.

[0021] The working principle of this utility model is as follows: During use, the wastewater and treatment agents generated during the production of acetate ester enter the filter frame 600 through the inlet pipe 610. The wastewater entering the filter frame 600 is initially filtered through the filter screen 640 in the filter frame 600, collecting and removing large particulate impurities. The filtered wastewater enters the housing 100 through the connecting pipe 120. Then, the motor 410 is started to drive the rotating rod 200 to rotate. The rotation of the rotating rod 200 can stir the wastewater in the housing 100, allowing it to react fully with the treatment agents. At the same time, when the rotating rod 200 rotates, it will drive the connecting plate 310 to rotate, allowing the sliding plate to rotate. The moving block 320 slides inside the annular sliding frame 300, thereby causing the connecting rod 330 and the arc-shaped scraper 340 to rotate. The rotation of the arc-shaped scraper 340 can clean the inner wall of the hemispherical bottom frame 110. When the rotating rod 200 rotates, it will drive the spiral stirring blade 500 to rotate, stirring the discharge pipe 130 to prevent excessive accumulation of flocculents in the discharge pipe 130 and blockage. After the device is used, the personnel can unscrew the locking screw 660 to pull the sliding plate 630 out of the installation port 620, thereby facilitating the removal of large particles of impurities intercepted and collected by the filter screen 640 and the cleaning and replacement of the filter screen 640.

[0022] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
