Description

Technical Field

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

[0002] The reference patent, titled "A Wastewater Treatment Equipment for Fine Chemical Production" (Authorization Announcement No.: CN214528420U, Authorization Announcement Date: 2021.10.29), includes a sedimentation and stirring tank, an inclined plate, a motor, a filter tank, lifting rods, and a filter jacket. The sedimentation and stirring tank has a motor at its bottom, fixedly connected to a rotating shaft. Several stirring blades are evenly distributed on both sides of the rotating shaft. An inclined plate is installed on the inner wall of the bottom of the sedimentation and stirring tank. Lifting rods are installed on the inner walls of both sides of the filter tank, with a filter jacket detachably connected to the bottom of each lifting rod. The filter jacket contains activated carbon. This equipment concentrates sedimentation and stirring in the same tank, improving wastewater treatment efficiency. The inclined plate on the inner wall of the bottom of the sedimentation and stirring tank allows waste to flow through the inclined plate to the drain pipe under gravity during sedimentation, facilitating waste cleaning. A three-layer filtration device is added to the filter tank to enhance the filtration effect.

[0003] Based on the aforementioned document, the treatment of chemical wastewater requires the use of chemical wastewater treatment equipment. Existing chemical wastewater treatment equipment first requires filtering the wastewater through a filter screen to reduce large particulate impurities, thereby facilitating subsequent treatment operations. However, the filtration efficiency of the filter screen in existing chemical wastewater treatment equipment will be affected after long-term use. Moreover, the filter screens of existing treatment equipment are mostly fixed and embedded in the box, making them difficult to disassemble and clean, which will affect the wastewater treatment efficiency. Therefore, this utility model provides a chemical wastewater treatment equipment. Utility Model Content

[0013] Beneficial effects

[0014] This utility model provides a wastewater treatment device for chemical industry. Compared with the prior art, it has the following advantages:

[0015] Beneficial effects:

[0016] 1. This chemical wastewater treatment equipment, when activated by a cleaning cylinder, drives the piston rod and transmission block to slide downwards synchronously. The sliding of the transmission block causes the transmission gear, transmission rod, and cleaning brush to slide downwards synchronously. As the transmission gear slides, it rolls on the surface of the linkage gear, thus starting to rotate. When the transmission gear rotates, it drives the transmission rod and cleaning brush to rotate synchronously. The cleaning brush washes the surface of the filter screen. With the cleaning mechanism, the height of the cleaning brush can be flexibly adjusted by the cleaning cylinder. During the up-and-down sliding of the cleaning brush, it rotates under the drive of the transmission gear and linkage gear. In this way, the surface of the filter screen can be washed by the cleaning brush, avoiding excessive adhesion of impurities on the surface of the filter screen, thereby improving the filtration quality and efficiency of the filter screen.

[0017] 2. This chemical wastewater treatment equipment is equipped with a disassembly and assembly mechanism, which enables quick disassembly and assembly of the filter screen, thus facilitating regular replacement and cleaning of the filter screen. Furthermore, the limit spring ensures that one end of the disassembly and assembly rod remains locked and fixed to the inner surface of the disassembly and assembly groove when not subjected to external force.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A wastewater treatment device for chemical industry includes a treatment tank 1, a filter screen 2 slidably connected inside the treatment tank 1, a disassembly mechanism 3 installed on the top of the treatment tank 1, and a cleaning mechanism 4 inside the treatment tank 1, the cleaning mechanism 4 including:

[0027] The cleaning assembly 41 includes a cleaning cylinder 411 installed on the top of the processing box 1. A piston rod 412 is slidably connected to the bottom of the cleaning cylinder 411. The surface of the piston rod 412 is slidably connected to the top of the processing box 1. The bottom of the piston rod 412 causes the cleaning brush 413 to slide through the transmission assembly 5. The surface of the cleaning brush 413 is in contact with the surface of the filter screen 2.

[0028] The linkage component 42 is located at the bottom of the inner cavity of the processing box 1 and is used to drive the cleaning brush 413 to rotate.

[0029] The treatment box 1 is mainly used for filtering chemical wastewater; the cleaning cylinder 411 is connected to an external air source through an air pipe; the piston rod 412 slides on the top of the treatment box 1; one side of the filter screen 2 is slidably connected to one side of the linkage plate 421.

[0030] In this embodiment, the transmission assembly 5 includes a transmission block 51 installed at the bottom of the piston rod 412. A transmission rod 52 is rotatably connected inside the transmission block 51. The surface of the transmission rod 52 is fixedly connected to one end of the cleaning brush 413. A transmission gear 53 is fixedly connected to one end of the transmission rod 52.

[0031] In this embodiment, the linkage assembly 42 includes a linkage plate 421 installed at the bottom of the inner cavity of the processing box 1. Multiple sets of linkage teeth 422 are fixedly connected to one side of the linkage plate 421, and the surface of the linkage teeth 422 meshes with the surface of the transmission gear 53.

[0032] By activating the cleaning cylinder 411, the piston rod 412 and the transmission block 51 slide downwards synchronously. The sliding of the transmission block 51 drives the transmission gear 53, the transmission rod 52, and the cleaning brush 413 to slide downwards synchronously. As the transmission gear 53 slides, it rolls on the surface of the linkage gear 422, thus starting to rotate. When the transmission gear 53 rotates, it drives the transmission rod 52 and the cleaning brush 413 to rotate synchronously. The cleaning brush 413 brushes the surface of the filter screen 2. With the cleaning mechanism 4, the height of the cleaning brush 413 can be flexibly adjusted by the cleaning cylinder 411. During the up-and-down sliding of the cleaning brush 413, it rotates under the drive of the transmission gear 53 and the linkage gear 422. In this way, the cleaning brush 413 can brush the surface of the filter screen 2, avoiding excessive impurities adhering to the surface of the filter screen 2, thereby improving the filtration quality and efficiency of the filter screen 2.

[0033] In this embodiment, the disassembly and assembly mechanism 3 includes a disassembly and assembly plate 31 installed on the top of the processing box 1. A disassembly and assembly rod 32 is slidably connected inside the disassembly and assembly plate 31. A control block 33 is fixedly connected to one end of the disassembly and assembly rod 32. The surface of the control block 33 is slidably connected to the inside of the disassembly and assembly plate 31. The top end of the control block 33 extends through to the top of the disassembly and assembly plate 31. A limit spring 34 is fixedly connected to one side of the control block 33. One end of the limit spring 34 is fixedly connected to the inner wall of the disassembly and assembly plate 31.

[0034] When the limiting spring 34 is not affected by external force, one end of the disassembly rod 32 will always be engaged with the inner surface of the disassembly groove 7.

[0035] The top of the disassembly plate 31 is provided with a limiting groove for the control block 33 to slide.

[0036] In this embodiment, a disassembly block 6 is fixedly connected to the surface of the filter screen plate 2, and a disassembly groove 7 is fixedly connected to the inner side of the disassembly block 6. The inner surface of the disassembly groove 7 is engaged with one end of the disassembly rod 32.

[0037] In this embodiment, a water inlet pipe 8 is fixedly connected to one side of the treatment tank 1, and a guide pipe 9 is fixedly connected to the other side of the treatment tank 1.

[0038] The inlet pipe 8 is connected to the chemical wastewater pipeline; the diversion pipe 9 is connected to the subsequent wastewater purification equipment.

[0039] With the installation and removal mechanism 3, the filter screen 2 can be quickly installed and removed, which facilitates the regular replacement and cleaning of the filter screen 2. In addition, the limit spring 34 will keep one end of the installation and removal rod 32 locked and fixed to the inner surface of the installation and removal groove 7 when not affected by external force.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0041] Chemical wastewater enters treatment tank 1 through inlet pipe 8, and after filtration in treatment tank 1, it is finally transported to subsequent treatment devices through guide pipe 9. After filtration, inlet pipe 8 needs to be connected to an external clean water source to flush the inside of treatment tank 1. At this time, the cleaning cylinder 411 is activated, which drives the piston rod 412 and transmission block 51 to slide downwards synchronously. The sliding of transmission block 51 will drive the transmission gear 53, transmission rod 52 and cleaning brush 413 to slide downwards synchronously. When the transmission gear 53 slides, it will roll on the surface of the linkage gear 422, thus starting to rotate. When the moving gear 53 rotates, it drives the transmission rod 52 and the cleaning brush 413 to rotate synchronously. The cleaning brush 413 brushes the surface of the filter screen 2. However, after a long period of operation, brushing may not be able to completely remove the impurities from the surface of the filter screen 2. At this time, the control block 33 can be moved to drive the two disassembly rods 32 on both sides to slide synchronously to the opposite side, so that one end of the disassembly rod 32 slides out of the disassembly groove 7, causing the limit spring 34 to be squeezed. Without the disassembly rod 32 locking and positioning, the filter screen 2 can be quickly removed from the treatment box 1 for replacement and cleaning.
