Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a water pollution treatment device. Background Art

[0002] Water pollution is caused by harmful chemical substances, which reduces or loses the use value of water and pollutes the environment. Sewage will cause harm to organisms in the water, affect their growth, and at the same time deteriorate the water quality of drinking water sources, affecting people's health. With the strengthening of environmental protection awareness, people pay more and more attention to the problem of water pollution and begin to filter and purify sewage to remove toxic substances such as impurities in the sewage, so that the sewage meets the water quality requirements for discharging into a certain water body or being reused again. Sewage treatment is widely used in various fields such as construction, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering.

[0003] Traditional sewage treatment filtering devices often use filter nets to remove large particles. To meet the filtering requirements, after the filter net has been working for a long time, a large amount of large particles accumulate and adsorb on the water-facing surface, making the filtering effect of the filter net worse. And the filtering device generally adopts an integrated structure. When discharging sewage and removing impurities from the filter net, the whole device needs to be disassembled and cleaned. The disassembly is relatively cumbersome, increasing the operation difficulty of the staff. Summary of the Invention

A bottom plate is fixedly connected to the bottom of the inner cylinder. A pushing mechanism is arranged at the bottom of the bottom plate;

[0006] The supporting mechanism includes two assembly plates installed on one side of the inner wall of the housing. Through rods are inserted through the tops of the two assembly plates. A reinforcement rod is fixedly connected to the tops of the two through rods. A limiting bottom plate is fixedly connected to the bottom of the surface of the two through rods. A first spring is arranged between the limiting bottom plate and the assembly plate, and the first spring is sleeved on the surface of the through rod.

[0015] 1. Through the settings of the outer shell, the first motor, the support mechanism, the top strip and the scraper, when in use, the first motor drives the outer shell to rotate. When the outer shell rotates, the water inlet groove at its top rotates from one filter screen to above another filter screen. When the outer shell rotates, it drives the support mechanism and the scraper to rotate at the same time. When the scraper rotates, it scrapes impurities from the used filter screen, pushes the impurities to the pushing port, and thus does not need to disassemble the filter screen for cleaning, improving the efficiency of water treatment. At the same time, the rotating outer shell drives the support mechanism to contact the top strip, and under the action of the top strip, the support mechanism supports the top filter screen, thereby strengthening the strength of the filter screen and avoiding damage to the filter screen caused by excessive sewage volume during filtration.

[0016] 2. Through the setting of the pushing mechanism, the second motor drives the driving rod to rotate, the driving rod rotates to drive the gear disk to rotate, the gear disk rotates to drive the two rack bars on both sides to move in parallel, and then the two rack bars move to drive the two pushing blocks to move through the second pushing port and the first pushing port in sequence. Thus, when the pushing block moves, the pushing surface of the pushing block pushes the impurities scraped by the scraper out of the outer shell, facilitating the cleaning of the scraped impurities. At the same time, the pushing blocks on both sides block the space between the outer shell and the inner cylinder, and thus the space between the outer shell and the inner cylinder is divided into steps for filtration, thereby improving the working efficiency of sewage filtration.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology of a water pollution treatment device in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Reference Figures 1-8 , a water pollution treatment device provided in this embodiment includes a shell 1, the shell 1 is connected to an inner cylinder 2 through a mounting plate 3 rotatably connected to the inner part thereof, filling pads are arranged on both sides of the inner top wall of the shell 1, a top shell 5 is rotatably connected to the top of the shell 1, a first motor 7 is installed on the top of the top shell 5, an output end of the first motor 7 is fixedly connected to the middle of the top of the shell 1, a first push port and a second push port are respectively opened on both sides of the shell 1 and the inner cylinder 2, a scraper 12 is fixedly connected to the inner top wall of the shell 1, the scraper 12 is located between the shell 1 and the inner cylinder 2, wherein the height of the scraper 12 is lower than the filling pad, and the bottom of the scraper 12 is in close contact with the filter screen 4, the filter screen 4 is installed on both sides of the mounting plate 3, a drainage bucket 6 is rotatably connected to the bottom of the shell 1, a bottom plate 9 is fixedly connected to the bottom of the inner cylinder 2, and a pushing mechanism 11 is arranged at the bottom of the bottom plate 9;

[0029] It also includes two top strips 10, the bottom of the top strips 10 is fixedly connected to the bottom plate 9, and the top of the top strips 10 is in contact with the bottom of the penetration rod;

[0030] The first motor 7 drives the housing 1 to rotate. One side of the top of the housing 1 is an inclined trough, and a water inlet trough is arranged at the bottom of the inclined trough. The inclined trough accelerates the rapid inflow of sewage into the water inlet trough, accelerating the flow and filtration of sewage. When the housing 1 rotates, the water inlet trough at its top rotates from one filter net 4 to above another filter net 4. At the same time, the filling pads on both sides of the inner top wall of the housing 1 move along with it to fill and seal the space between the inner top wall of the housing 1 and the top of the inner cylinder 2, preventing the outflow of sewage from the space between the inner top wall of the housing 1 and the top of the inner cylinder 2 when the sewage volume is too large, ensuring the tightness of the separated space. When the housing 1 rotates, it also drives the support mechanism 8 and the scraper 12 to rotate. When the scraper 12 rotates, it scrapes impurities from the used filter net 4 and pushes the impurities to the pushing port, so that the filter net 4 can be cleaned without disassembly;

[0031] The support mechanism 8 includes two fitting plates 801 installed on one side of the inner wall of the housing 1. Through rods are penetrated through the tops of the two fitting plates 801. A reinforcing rod 802 is fixedly connected to the tops of the two through rods. A limiting bottom plate is fixedly connected to the bottom of the surfaces of the two through rods. A first spring 803 is arranged between the limiting bottom plate and the fitting plate 801. The first spring 803 is sleeved on the surface of the through rod. Buffer members 804 are arranged on both sides of the surface of the reinforcing rod 802. When the housing 1 moves, it drives the through rod to contact the top strip 10. Then, under the action of the top strip 10, the limiting bottom plate compresses the first spring 803 upward, causing the reinforcing rod 802 to move upward, and then supporting the filter net 4 above the top of the buffer member 804 to strengthen the strength of the filter net 4; When the conventional filter net 4 is impacted by water flow, the mesh holes are easily torn by the impact. The support mechanism 8 supports the filter net 4 through the reinforcing rod 802 and the buffer member 804, playing a buffering effect, thus avoiding damage to the filter net 4 caused by excessive sewage volume during filtration;

[0032] The buffer member 804 includes a collar 8401 sleeved on the surface of the reinforcing rod 802. The inside of the collar 8401 is slidably connected to the reinforcing rod 802 up and down through a through rod. Two second springs 8402 are arranged between the inner top wall and the inner bottom wall of the collar 8401 and the surface of the reinforcing rod 802. The two ends of the two second springs 8402 are fixedly connected to the collar 8401 and the reinforcing rod 802, and the two second springs 8402 are sleeved on both sides of the surface of the through rod. The collar 8401 contacts the bottom of the filter net 4. When the water volume is too large, the filter net 4 presses down the collar 8401, and under the action of the through rod, the collar 8401 is vertically compressed downward to compress the second spring 8402, buffering the pressure of the water volume through the second spring 8402.

[0033] Specifically, such as Figure 2 and Figure 4As shown, the pushing mechanism 11 includes a second motor 1101 installed at the bottom of the base plate 9, the output end of the second motor 1101 is connected to a driving rod 1102, the top of the driving rod 1102 is connected to a toothed disc 1103, both sides of the toothed disc 1103 are meshed with gear rods 1104, the bottoms of the two gear rods 1104 are slidably connected to the base plate 9, the ends of one end of the two gear rods 1104 are connected to a pushing block 1105 adapted to the first pushing port and the second pushing port, the second motor 1101 drives the driving rod 1102 to rotate, and the rotation of the driving rod 1102 drives the toothed disc 1103 to rotate The toothed disc 1103 rotates to drive the gear rods 1104 on both sides to move in parallel, and then the two gear rods 1104 move to drive the two pushing blocks 1105 to move, passing through the second pushing port and the first pushing port in turn, and then when the pushing block 1105 moves, the pushing surface of the pushing block 1105 pushes the impurities scraped by the scraper 12 out of the outer shell 1, so as to facilitate the cleaning of the scraped impurities. At the same time, the pushing blocks 1105 on both sides block the space between the outer shell 1 and the inner cylinder 2, and then separate the space between the outer shell 1 and the inner cylinder 2 for step-by-step filtration, thereby improving the working efficiency of sewage filtration.

[0034] The second motor 1101 is located between the partition plate 13 and the bottom plate 9. A motor cavity is formed between the partition plate 13 and the bottom plate 9 to protect the second motor 1101.

[0035] Specifically, Figure 2 and Figure 5 As shown, the upper surface of the bottom plate 9 is rotatably connected to the outer shell 1, wherein the bottom plate 9 is fixedly installed inside the drainage bucket 6, and a partition plate 13 is provided inside the drainage bucket 6, wherein the partition plate 13 is connected to the bottom plate 9 through a drainage pipe 14, and then a wiring port for wiring is opened on the surface of the drainage bucket 6.

[0036] Among them, the drain pipe 14 passes through the partition plate 13 to discharge the filtered water into the drain bucket 6, so as to prevent the water from contacting the inner wall of the drain bucket 6 when the drain pipe 14 drains water, causing splashes to touch the second motor 1101 and causing damage to the second motor 1101.

[0037] Working principle: First, the sewage is connected to the water inlet pipe on the top of the top shell 5, and then the sewage flows into the water inlet groove at the bottom of the inclined groove on the top side of the shell 1. The inclined groove accelerates the sewage to flow into the water inlet groove quickly, and then the sewage passes through the filter 4 to filter the sewage. When the filter 4 is filtering, the reinforcement rod 802 and the buffer 804 below it support the filter 4 on the top to strengthen the strength of the filter 4. At the same time, when the water volume is too large, the filter 4 presses down the ring 8401. Under the action of the penetrating rod, the pressing ring 8401 vertically compresses the second spring 8402 downward, and the second spring 8402 buffers the water pressure to avoid the amount of sewage during filtration. The filter screen 4 is too large to be damaged, and then the filtered water is discharged from the drain pipe 14 into the drain bucket 6 and finally discharged. When there are many impurities adsorbed and accumulated on the water-facing surface of the filter screen 4, the injection of sewage is stopped, and then the second motor 1101 drives the driving rod 1102 to rotate, and the driving rod 1102 rotates to drive the toothed disc 1103 to rotate, and the rotation of the toothed disc 1103 drives the gear rods 1104 on both sides to move in parallel, and then the two gear rods 1104 move to drive the two push blocks 1105 to move and draw the two push blocks 1105 back into the inner cylinder 2 to open the space between the outer shell 1 and the inner cylinder 2, and then the outer shell 1 rotates to make the water inlet groove on the top of the filter screen 4 from one of the filter screens 4. The outer shell 1 rotates to the top of another filter screen 4, and at the same time, the filling pads on both sides of the inner top wall of the outer shell 1 follow the movement to fill and seal the space between the inner top wall of the outer shell 1 and the top of the inner tube 2, so as to prevent excessive sewage from flowing out from between the inner top wall of the outer shell 1 and the top of the inner tube 2 during sewage filtration, thereby ensuring the sealing of the separated space. When the outer shell 1 rotates, it also drives the support mechanism 8 and the scraper 12 to rotate. When the scraper 12 rotates, it scrapes the used filter screen 4 and pushes the impurities to the push port, so that the filter screen 4 does not need to be disassembled for cleaning. At the same time, the rotating outer shell 1 drives the support mechanism 8 to rotate, so that it moves from one top strip 10 to another top strip 1 0, under the action of the two top bars 10, the supporting mechanism 8 performs step-by-step replacement support on the two filter screens 4. After the impurities are pushed to the push port, the second motor 1101 moves again, driving the driving rod 1102 to rotate in the opposite direction. The driving rod 1102 rotates in the opposite direction to drive the toothed disc 1103 to rotate in the opposite direction. The toothed disc 1103 rotates in the opposite direction to drive the gear rods 1104 on both sides to move in parallel. Subsequently, the two gear rods 1104 move to drive the two pushing blocks 1105 to move, passing through the second push port and the first push port in turn. Then, when the pushing block 1105 moves, the pushing surface of the pushing block 1105 pushes the impurities scraped by the scraper 12 out of the outer shell 1, so as to facilitate the cleaning of the scraped impurities.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to a water pollution treatment device and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
