Description

Technical Field

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

[0002] Wastewater treatment is a crucial step in chemical industrial production, especially wastewater containing solid particles, suspended solids, or chemical precipitates. Direct discharge of untreated wastewater can easily cause environmental pollution and even affect subsequent processes. Traditional wastewater treatment equipment typically uses fixed filtration structures, such as filter screens or cartridges, which are prone to clogging after prolonged use, leading to decreased filtration efficiency.

[0003] When performing preliminary filtration of suspended particles and fine fibers in chemical wastewater, conventional filter screens are generally used to intercept the impurities first. The wastewater is then filtered by flowing through the filter screen. However, the interception speed is slow, the interception effect will become worse and worse, and it is easy to cause blockages, which are difficult to clean. Utility Model Content

[0004] The technical problem this invention aims to solve is that using a filter screen to intercept impurities and filtering wastewater by passing it through the screen results in a slow interception speed, a progressively worse interception effect, and easy clogging, which is difficult to clean.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a chemical industrial wastewater treatment device, including a tank, a sealing door hinged to the front side of the tank, an inlet pipe fixedly connected to the top of the tank, and a drain pipe provided on one side of the bottom of the tank, and further including...

[0006] The filter assembly, located inside the housing, includes a filter cartridge that is detachable inside the housing. An inner ring is fixedly connected inside the filter cartridge. A support column perpendicular to the filter cartridge is rotatably connected to the bottom of the housing. A drive mechanism for rotating the support column is provided at the lower end of the support column.

[0007] Furthermore, a support plate is fixedly connected to the upper end of the support column, a bottom frame is fixedly connected to the bottom of the filter cylinder, and symmetrically distributed inserts are fixedly connected to the top of the support plate. The bottom of the bottom frame passes through the inserts and is slidably connected to them. A positioning block is threaded onto the insert.

[0008] Furthermore, the filter cartridge has an opening at the top center, the lower end of the water inlet pipe passes through the opening and is located inside the filter cartridge, and the middle part of the water inlet pipe is a flexible hose.

[0009] Furthermore, an electric push rod is fixedly installed on the inner top of the box, and it is symmetrically distributed relative to the water inlet pipe. The free end of the electric push rod is fixedly connected to a connecting plate, and the water inlet pipe passes through the connecting plate and is fixedly connected to it.

[0010] Furthermore, the bottom wall of the housing is fixedly connected to a bottom plate arranged opposite to the left and right. The driving mechanism includes a horizontal shaft rotatably connected between the opposite side walls of the bottom plate. Adjacent bevel gear one and worm gear are fixedly connected on the horizontal shaft. The lower end of the support column is fixedly connected to a bevel gear two that meshes with bevel gear one. A servo motor is fixedly installed at the bottom of the housing. The output end of the servo motor is fixedly connected to a worm that meshes with the worm gear.

[0011] Furthermore, the bottom of the box is inclined from left to right, and the drain pipe is located on the right side of the box.

[0012] The beneficial effects of this utility model after adopting the above structure are as follows:

[0013] (1) Insert the filter cylinder filled with filter elements into the insert at the top of the support plate, screw the positioning block to fix the filter cylinder in place, control the electric push rod to extend and push the water inlet pipe downward so that its lower end extends into the filter cylinder, ensuring that the sewage input channel is in place.

[0014] (2) The horizontal shaft is driven to rotate by the meshing transmission of the worm and the worm wheel, which in turn drives the first bevel gear to rotate the second bevel gear. The support column drives the filter cylinder to rotate, and the centrifugal force is used to accelerate the filtration of sewage. Solid particles are thrown to the inner wall of the filter cylinder and intercepted by the filter screen. Dissolved pollutants are adsorbed by activated carbon. The treated sewage is discharged from the drain pipe under the guidance of the bottom of the tank.

[0022] like Figure 1-2 As shown, a chemical industrial wastewater treatment device includes a housing 1, a sealing door 2 hinged to the front of the housing 1, an inlet pipe 3 fixedly connected to the top of the housing 1, a drain pipe 4 provided on one side of the bottom of the housing 1, the inner bottom of the housing 1 being inclined from left to right, the drain pipe 4 being located on the right side of the housing 1, and also includes a filter assembly located inside the housing 1.

[0023] like Figure 1-4 As shown, to improve the efficiency of wastewater treatment, the filter assembly includes a filter cylinder 5 detachably installed inside the housing 1. An inner ring 6 is fixedly connected inside the filter cylinder 5. A support column 7 perpendicular to the bottom of the housing 1 is rotatably connected to it. A drive mechanism for rotating the support column 7 is provided at its lower end. A bottom plate 14, arranged opposite each other, is fixedly connected to the bottom wall of the housing 1. The drive mechanism includes a horizontal shaft 15 rotatably connected between the opposite side walls of the bottom plate 14. Adjacent bevel gears 16 and worm gears 17 are fixedly connected to the horizontal shaft 15. The support column... The lower end of the support column 7 is fixedly connected to a bevel gear 18 that meshes with bevel gear 16. A servo motor 19 is fixedly installed at the bottom of the housing 1. The output end of the servo motor 19 is fixedly connected to a worm 20 that meshes with a worm wheel 17. The horizontal shaft 15 is rotated through the meshing transmission of the worm 20 and the worm wheel 17, which in turn causes bevel gear 16 to drive bevel gear 18 to rotate. The support column 7 drives the filter cylinder 5 to rotate, and centrifugal force is used to accelerate the filtration of sewage. Solid particles are thrown to the inner wall of the filter cylinder 5 and intercepted by the filter screen. Dissolved pollutants are adsorbed by activated carbon.

[0024] like Figure 2-4 As shown, to facilitate the installation and removal of the filter cartridge 5, a support plate 8 is fixedly connected to the upper end of the support column 7, a bottom frame 9 is fixedly connected to the bottom of the filter cartridge 5, and symmetrically distributed insertion columns 10 are fixedly connected to the top of the support plate 8. The bottom of the bottom frame 9 passes through the insertion columns 10 and is slidably connected to them. A positioning block 11 is threaded onto the insertion column 10. The filter cartridge 5 filled with filter elements is inserted into the insertion column 10 at the top of the support plate 8, and the positioning block 11 is screwed on to fix the filter cartridge 5 in place. When replacing the filter cartridge 5, the installation steps of the filter cartridge 5 can be reversed.

[0025] like Figure 3-4As shown, to facilitate the entry of sewage, the top center of the filter cylinder 5 is set with an opening. The lower end of the water inlet pipe 3 passes through the opening and is located inside the filter cylinder 5. The middle part of the water inlet pipe 3 is set with a flexible hose. An electric push rod 12 is fixedly installed on the top of the inner box 1, and it is symmetrically distributed with respect to the water inlet pipe 3. The free end of the electric push rod 12 is fixedly connected to a connecting plate 13. The water inlet pipe 3 passes through the connecting plate 13 and is fixedly connected to it. By controlling the electric push rod 12 to extend, the water inlet pipe 3 is pushed downward so that its lower end extends into the interior of the filter cylinder 5, ensuring that the sewage input channel is in place.

[0026] In practical use, the inner wall of the filter cylinder 5 and the outer wall of the inner ring 6, as well as the interior of the inner ring 6, can be filled with corresponding filter elements, such as filter screens and activated carbon. Open the sealing door 2, insert the filter cylinder 5 into the insertion post 10, and install and position the filter cylinder 5 by screwing on the positioning block 11. Then, control the electric push rod 12 to extend so that the lower end of the water inlet pipe 3 enters the interior of the filter cylinder 5. Then, add sewage through the water inlet pipe 3. The sewage enters the inner ring 6 of the filter cylinder 5. Turn on the servo motor 19. The meshing transmission between the worm gear 20 and the worm wheel 17 causes the bevel gear 16 on the horizontal shaft 15 to drive the bevel gear 18 to rotate. This causes the filter cylinder 5 at the upper end of the support column 7 to rotate, centrifuging the sewage and accelerating the sewage treatment efficiency. The sewage that is thrown out is guided at the bottom of the box 1 and discharged through the drain pipe 4. The filter cylinder 5 can be replaced periodically to ensure the sewage treatment effect. When replacing the filter cylinder 5, simply reverse the installation steps of the filter cylinder 5.
