Description

Technical Field

[0001] This patent relates to the field of wastewater treatment technology, specifically a wastewater treatment recycling device. Background Technology

[0002] Wastewater from coking plants is usually pretreated by using filters to trap large debris and prevent clogging of downstream pipes. Existing pretreatment tanks have filters installed on top. Traditionally, when there is too much debris on the filters, they need to be manually disassembled and lifted to a cleaning position for cleaning. Manual cleaning greatly increases labor intensity and reduces cleaning efficiency. Therefore, we propose a wastewater treatment recycling device. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this patent is to provide a wastewater treatment recycling device. This solution uses a hinge to connect the pretreatment tank and the filter screen. When it is necessary to clean the residue on the top of the filter screen, simply flip the filter screen along the hinge point until the top of the filter screen is facing down (180 degrees). At this point, the residue on the filter screen will fall off. Alternatively, the piston rod of the electric actuator can be frequently extended and retracted to impact the flipped filter screen, causing the filter screen to frequently impact the top of the support plate. The impact force will then cause the residue to fall off, improving cleaning efficiency.

[0004] The technical solution adopted by this patent to solve its technical problem is: a sewage treatment circulation device, including a pretreatment box and a hinge. A drain pipe is embedded in the bottom of the left side wall of the pretreatment box, a sewage pipe is provided on the upper side of the pretreatment box, and a filter screen is hinged to the top right end of the pretreatment box through the hinge. A connecting plate is fixedly installed at the bottom of the outer right side wall of the pretreatment box, a support plate is fixedly installed at the top right side of the connecting plate, a mounting base is fixedly installed at the middle of the right side of the support plate, and an electric push rod is fixedly installed at the top of the mounting base. A wheel seat is fixedly installed at the top of the piston rod of the electric actuator, and a top wheel is rotatably connected inside the wheel seat.

[0005] Furthermore, a buffer pad is fixedly installed on the top of the support plate, and the buffer pad is one of a rubber pad or a silicone pad.

[0006] Furthermore, the wheel seat includes a U-shaped seat and a bolt. The U-shaped seat has square holes on both the left and right sides. The left end of the bolt passes through the square hole and the middle hole of the top wheel in sequence and is screwed with a nut. The inner side of the nut is pressed against the outer side of the U-shaped seat. A square part is integrally formed on the threaded side wall of the bolt. The outer side wall of the square part contacts and fits against the inner side wall of the square hole. The diameter of the top wheel is larger than the width of the U-shaped seat.

[0007] Furthermore, a blank area is provided on the threaded sidewall of the bolt, and the middle hole of the top wheel is fitted into the blank area.

[0008] Furthermore, a water distribution pipe is fixedly installed at the bottom end of the sewage pipe, and there are multiple water distribution pipes, with the bottom ends of the multiple water distribution pipes evenly arranged on the top upper side of the filter screen.

[0009] Furthermore, the sewage pipe is equipped with a moving mechanism.

[0010] The beneficial effects of this patent are: 1. This solution uses a hinge to connect the pretreatment box and the filter screen. When it is necessary to clean the residue on the top of the filter screen, simply flip the filter screen along the hinge point until the top of the filter screen is facing down (180 degrees). At this time, the residue on the filter screen will fall off. Alternatively, the piston rod of the electric push rod can be frequently extended and retracted to impact the flipped filter screen, causing the filter screen to frequently hit the top of the support plate. The impact force will then cause the residue to fall off, improving cleaning efficiency. Attached Figure Description

Detailed Implementation

[0016] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0017] See Figure 1 , Figure 2 , Figure 3 and Figure 4This is a schematic diagram of the structure of this patent. A sewage treatment circulation device includes a pretreatment tank 1 and a hinge. A drain pipe 2 is embedded in the bottom of the left side wall of the pretreatment tank 1, a sewage pipe 3 is provided on the upper side of the pretreatment tank 1, and a filter screen 4 is hinged to the top right end of the pretreatment tank 1. A connecting plate 5 is fixedly installed on the bottom of the outer right side wall of the pretreatment box 1. A support plate 6 is fixedly installed on the top right side of the connecting plate 5. A mounting base 7 is fixedly installed in the middle of the right side of the support plate 6. An electric push rod 8 is fixedly installed on the top of the mounting base 7. A wheel seat 9 is fixedly installed at the top of the piston rod of the electric actuator 8, and a top wheel 10 is rotatably connected inside the wheel seat 9.

[0018] By setting the top wheel 10, the smoothness of the disengagement between the piston rod tip of the electric push rod 8 and the filter screen 4 can be increased.

[0019] Traditionally, when cleaning a filter screen, if there is too much residue on it, the screen needs to be disassembled manually and then lifted to the cleaning position for cleaning. Manual cleaning greatly increases labor intensity and reduces cleaning efficiency.

[0020] This solution uses a hinge to connect the pretreatment box 1 and the filter screen 4. When cleaning the residue on the top of the filter screen 4, simply flip the filter screen 4 along the hinge point until it is flipped to the desired position. Figure 1 The top of the middle filter screen 4 can be turned downwards (rotated 180 degrees). At this time, the debris on the filter screen 4 can fall off. Alternatively, the piston rod of the electric push rod 8 can be extended and retracted frequently, thereby impacting the rotated filter screen. This causes the filter screen to frequently impact the top of the support plate 6, and the debris can fall off through the impact force, thus improving cleaning efficiency.

[0021] Pretreatment box 1: Length 800 - 1200mm, Width 600 - 900mm, Height 500 - 800mm, made of stainless steel, wall thickness 3 - 5mm.

[0022] Drain pipe 2: Pipe diameter 50-80mm, material is UPVC or stainless steel.

[0023] Sewage pipe 3: Pipe diameter 80-120mm, material is stainless steel.

[0024] Filter screen 4: The size is adapted to the top opening of the pretreatment box 1. It is generally 750-1150mm long and 550-850mm wide. The mesh size can be selected between 1-5mm according to the sewage treatment precision requirements. The material is stainless steel wire mesh with a thickness of 1-2mm.

[0025] Connecting plate 5: Length 500 - 700mm, Width 100 - 150mm, Thickness 10 - 15mm, made of stainless steel.

[0026] Support plate 6: Height 400 - 600mm, Width 100 - 150mm, Thickness 10 - 15mm, made of stainless steel.

[0027] Mounting base 7: Adapted to the size of electric actuator 8, made of steel plate by welding or casting, and the material is Q235 steel.

[0028] Electric linear actuator 8: Stroke 200 - 400mm, thrust 500 - 1000N, voltage 220V, speed 5 - 10mm / s.

[0029] Top roller 10: Diameter 40 - 60mm, width 20 - 30mm, material is nylon or polyurethane, center hole diameter 10 - 12mm.

[0030] Specifically, a buffer pad 11 is fixedly installed on the top of the support plate 6. The buffer pad 11 is either a rubber pad or a silicone pad.

[0031] The buffer pad 11 reduces the noise of the filter 4 hitting the support plate 6.

[0032] Buffer pad 11: 10-20mm thick, length to fit the top of support plate 6, width 80-120mm, material is rubber or silicone.

[0033] Specifically, the wheel seat 9 includes a U-shaped seat 12 and a bolt 14. The U-shaped seat 12 has square holes 13 on both the left and right sides. The left end of the bolt 14 passes through the square hole 13 and the middle hole of the top wheel 10 in sequence and is screwed with a nut 15. The inner side of the nut 15 is pressed against the outer side of the U-shaped seat 12. A square part 16 is integrally formed on the threaded side wall of the bolt 14. The outer side wall of the square part 16 contacts and fits against the inner side wall of the square hole 13. The diameter of the top wheel 10 is larger than the width of the U-shaped seat 12.

[0034] Traditional wheel mounts are fixed by bolts passing directly through the wheel. However, as the wheel rotates, the friction between the wheel's central hole and the bolt can easily loosen the bolt and the nut connected to it.

[0035] This solution uses the outer wall of the square part 16 to contact and fit against the inner wall of the square hole 13 for bolt 14 positioning, thus preventing the bolt 14 and nut 15 from loosening.

[0036] Specifically, a blank area 17 is provided on the threaded side wall of the bolt 14, and the middle hole of the top wheel 10 is fitted onto the blank area 17.

[0037] No threads are provided in the blank area 17 to increase the sliding ability with the middle hole of the top wheel 10.

[0038] Specifically, a water distribution pipe 18 is fixedly installed at the bottom of the sewage pipe 3. There are multiple water distribution pipes 18, and the bottom ends of the multiple water distribution pipes 18 are evenly arranged on the top upper side of the filter screen 4.

[0039] Water distribution pipe 18: Quantity 4-8, pipe diameter 20-30mm, material is stainless steel.

[0040] The water distribution pipe 18 is used to evenly distribute the coking wastewater discharged from the sewage pipe 3 onto the filter screen 4, thereby increasing the utilization rate of each position of the filter screen 4.

[0041] Specifically, a moving mechanism is provided on sewage pipe 3.

[0042] The moving mechanism can be a cylinder or a screw mechanism. When the filter screen 4 is flipped, the sewage pipe 3 can be moved to the upper position away from the filter screen 4 by the moving mechanism.

[0043] Working principle: Coking wastewater flowing from sewage pipe 3 passes through filter screen 4, where residue is trapped. The wastewater passing through filter screen 4 is discharged through drain pipe 2 to the subsequent fine treatment station. When there is too much residue on filter screen 4, it can be flipped along the hinge point until it is flipped to the desired consistency. Figure 1 The top of the middle filter screen 4 can be turned downwards (rotated 180 degrees). At this time, the debris on the filter screen 4 can fall off. Alternatively, the piston rod of the electric push rod 8 can be extended and retracted frequently, thereby impacting the rotated filter screen. This causes the filter screen to frequently impact the top of the support plate 6, and the debris can fall off through the impact force, thus improving cleaning efficiency.

[0044] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent. In terms of the technical aspects of this design principle, the setting of the device's power mechanism, power supply system and control system is not fully described. However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0045] This solution uses a hinge to connect the pretreatment box and the filter screen. When it is necessary to clean the residue on the top of the filter screen, simply flip the filter screen along the hinge point until the top of the filter screen is facing down (180 degrees). At this time, the residue on the filter screen will fall off. Alternatively, the piston rod of the electric actuator can be frequently extended and retracted to impact the flipped filter screen, causing the filter screen to frequently hit the top of the support plate. The impact force will then cause the residue to fall off, improving cleaning efficiency.
