Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically to a wastewater treatment device for chemical production. Background Technology

[0002] Chemical industry is an abbreviation for "chemical process", "chemical industry", "chemical engineering", etc. All technologies that use chemical methods to change the composition and structure of substances or synthesize new substances belong to chemical production technology, also known as chemical process. The products obtained are called chemicals or chemical products. Initially, these products were produced in handicraft workshops, which later evolved into factories and gradually formed a specific production industry, namely the chemical industry. Chemical engineering is a science that studies the common laws of the production process of chemical products. The relationship between humans and chemical industry is very close. Some chemical products have played an epoch-making role in the history of human development. Their production and application even represent a certain historical stage of human civilization.

[0003] In the treatment of wastewater from chemical production, multi-stage filtration is often used. However, in existing filtration devices, impurities accumulate on the filter plates, making cleaning difficult. Therefore, the filter plates need to be removed and cleaned after use, which causes inconvenience. Furthermore, it is inconvenient to clean the inner wall of the filter box during use. Therefore, we propose a wastewater treatment device for chemical production. Utility Model Content

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-3 This is the first embodiment of the present invention, providing a wastewater treatment device for chemical production, including a filter box 1, with an outlet pipe 11 fixedly connected to the left side below the filter box 1, and the interior of the filter box 1 including:

[0026] The filter assembly 2 includes multiple filter plates 21, which are cone-shaped. Each of the four sides of the opposite side of the multiple filter plates 21 is fixedly connected to a connecting scraper 22. The opposite sides of the multiple connecting scrapers 22 are in contact with the inner wall of the filter box 1. A drain pipe 23 is fixedly connected to the bottom of the lower filter plate 21. The lower end of the drain pipe 23 penetrates the lower side of the inner wall of the filter box 1 to its bottom.

[0027] The cleaning component 3 includes a drive rod 31, with multiple scrapers 32 fixedly connected to the rod wall of the drive rod 31, and multiple plugs 33 fixedly connected to the rod wall of the drive rod 31. The multiple scrapers 32 and plugs 33 are arranged alternately, and the multiple plugs 33 are all located inside the filter plate 21.

[0028] A limiting shell 24 is fixedly connected to the lower side of the inner wall of the filter box 1. The inner wall of the limiting shell 24 is slidably connected to the opposite side of the scraper 32 on the lower side through an annular slider. The lower end of the drain pipe 23 is rotatably connected to the lower side of the inner wall of the filter box 1.

[0029] A drive assembly 25 is provided on the left side of the filter box 1. The drive assembly 25 includes a support platform 251. A drive motor 252 is fixedly connected to the top of the support platform 251. A gear 253 is fixedly connected to the output end of the drive motor 252. An external gear ring 254 is meshed with the right side of the gear 253. A connecting shell 255 is fixedly connected to the inner wall of the external gear ring 254.

[0030] The right side of the support platform 251 is fixedly connected to the left side of the filter box 1, the lower end of the connecting shell 255 is fixedly connected to the upper part of the filter plate 21, and the four sides of the connecting shell 255 are rotatably connected to the upper part of the filter box 1 through a rotating shaft.

[0031] During use, wastewater is injected into filter box 1. The wastewater is filtered step by step by multiple filter plates 21 in filter box 1. The filtered wastewater is discharged through the outlet pipe 11 on filter box 1.

[0032] When the filter plate 21 is in use, the drive motor 252 on the support platform 251 is started, so that the drive motor 252 can drive the external gear ring 254 on the connecting shell 255 to rotate through the gear 253. The connecting shell 255 can drive the filter plate 21 on the upper side to rotate. The filter plates 21 are connected by the connecting scraper 22, so all the filter plates 21 are driven to rotate at the same time. The connecting scraper 22 between the filter plates 21 scrapes off the impurities on the inner wall of the filter box 1.

[0033] During wastewater filtration, all the plugs 33 on the drive rod 31 are located in the filter plate 21 to prevent impurities on the filter plate 21 from falling downwards, thus enabling wastewater filtration. After wastewater filtration is completed, when it is necessary to clean the impurities on the filter plate 21, the scraper 32 on the drive rod 31 moves downwards, bringing the scraper 32 close to the inner wall of the filter plate 21. All the plugs 33 move away from the filter plate 21, and the lower plugs 33 exit from the drain pipe 23 to the bottom of the drain pipe 23. At this time, with the rotation of the filter plate 21, the scraper 32 can scrape off the impurities on the filter plate 21, and the scraped impurities fall down through the opening on the filter plate 21 until they fall into the drain pipe 23 and are discharged through the drain pipe 23.

[0034] Example 2

[0035] Reference Figure 1-3 In the second embodiment of this utility model, an adjustment component 34 is provided above the filter box 1. The adjustment component 34 includes a support frame 341. An internal threaded sleeve 342 is fixedly connected to the inner wall of the support frame 341. A threaded rod 343 is threadedly connected to the inner wall of the scraper 32. A knob 344 is fixedly connected to the upper end of the plug 33.

[0036] The front and rear ends of the support frame 341 are fixedly connected to the front and rear sides of the filter box 1, respectively, and the lower end of the threaded rod 343 is fixedly connected to the upper end of the drive rod 31.

[0037] During use, when it is necessary to move the scraper 32 and the plug 33 on the drive rod 31, the knob 344 is turned so that the knob 344 drives the threaded rod 343 to rotate. Under the action of the internal threaded sleeve 342 in the support frame 341, the threaded rod 343 rotates and causes the drive rod 31 to move up and down. Therefore, after the drive rod 31 moves, the scraper 32 and the plug 33 on the drive rod 31 can move.

[0038] The remaining structure is the same as that in Example 1.
