Description

Technical Field

[0001] The utility model belongs to the technical field of sewage purification devices, and specifically relates to a sewage purification device for environmental protection. Background Technique

[0002] The sewage purification device is a process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Classified by the source of sewage, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage, and medical sewage, etc. Domestic sewage is the sewage generated in daily life, which refers to a complex mixture of various forms of inorganic and organic substances. Classified by the nature of water pollution, water pollution is divided into two categories: one is natural pollution; the other is human pollution. Currently, the more harmful one to water bodies is human pollution. Water pollution can be mainly divided into three categories: chemical pollution, physical pollution, and biological pollution according to different pollution impurities.

[0003] The patent document with the publication number of CN217555912U in the prior art provides a sewage purification device for environmental protection, including a box body. The bottom of the right inner side wall of the box body is fixedly connected with a water pump. The water suction port of the water pump is interconnected with a suction pipe. The front end of the suction pipe is fixedly connected with a filter screen. The water discharge port of the water pump is interconnected with a transmission pipe. It solves the problem that when replacing the filtering mechanism, professional tools are needed to disassemble the shell, disconnect the connections between various pipelines, and then release the fixation of the filter pipe to be able to replace it. The operation process is relatively cumbersome. And when pumping sewage, solid substances in the sewage will be pumped into the water pump, which will cause the water pump to be blocked at least, and damage the water pump at worst, resulting in the device being unable to be used, and it is suitable for being widely promoted and used.

[0004] However, in the process of using the existing sewage purification device for environmental protection, due to the fact that there are more impurities in the sewage, and during the filtration process, the impurities will accumulate and form sludge, and then the sludge will be stored in the sewage purification device. At the same time, when the filtering components in the sewage purification device filter sewage, they will also retain more impurities. And when cleaning the impurities on the filtering components and the sludge in the sludge tank, it is necessary for the staff to disassemble and clean the device, resulting in a large cleaning difficulty.

[0005] Therefore, the technical personnel in this field have proposed a sewage purification device for environmental protection to solve the problems raised in the background technique. Content of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides a sewage purification device for environmental protection to solve the problems in the prior art that when cleaning the impurities on the filtering components and the sludge in the sludge tank, it is necessary for the staff to disassemble and clean the device, resulting in a large cleaning difficulty, etc.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. In the utility model, through the arranged cleaning motor, lifting screw rod, lifting frame, cleaning plate, sludge tank and filter tank, when using the sewage purification device for environmental protection, sewage enters the water collecting tank from the water inlet pipe, and then the sewage is filtered by the collecting net, so that larger garbage in the sewage is blocked. Then the water enters the primary sedimentation tank, and the primary sedimentation tank precipitates the water. The precipitated water enters the contact tank through the connecting pipe, and the contact tank carries out a chemical reaction with the water to purify the water. Then the water enters the sedimentation tank through the connecting pipe for secondary sedimentation. Then the water enters the filtration tank through the connecting pipe, and the filter tank filters and purifies the water to make the water meet the discharge standard. Then the water enters the clear water tank through the connecting pipe and is discharged from the drain pipe. And the precipitated sludge is pumped by the sludge pump and transported to the sludge tank in the sludge pool through the sludge pipe to be collected. When cleaning is required, the staff starts the cleaning motor, and the cleaning motor drives the lifting screw rod to rotate. Due to the rotation direction of the lifting screw rod, the lifting frame will move downward. When the lifting frame drives the cleaning plate to move upward, the sludge tank and the filter tank under the cleaning plate will move out of the purification main body. At this time, the staff can clean the sludge tank and the filter tank. Therefore, it is not necessary for the staff to disassemble the components for cleaning, thus reducing the cleaning difficulty and facilitating the staff to maintain and manage the sewage purification device.

[0025] As shown in the attached Figure 1 to the attached Figure 4 figures:

[0026] Embodiment 1: A sewage purification device for environmental protection, including a purification main body 2.

A sludge tank 14 is fixedly connected to one side of the filter tank 13. A clear water tank 15 is fixedly connected to one side of the sludge tank 14.

[0027] As can be seen from the above, by starting the cleaning motor 6, the cleaning motor 6 drives the lifting screw rod 7 to rotate, and the lifting frame 8 will move downward due to the rotation direction of the lifting screw rod 7. When the lifting frame 8 drives the cleaning plate 9 to move upward, the sludge tank 901 and the filter tank 902 under the cleaning plate 9 will move out of the purification main body 2, and at this time, the staff can clean the sludge tank 901 and the filter tank 902.

[0028] Embodiment 2: A water collection tank 3 is fixedly connected to the top of the purification main body 2. A water inlet pipe 4 is fixedly connected to the top of the water collection tank 3. A collection net 301 is fixedly connected to the inside of the water collection tank 3.

[0029] As can be seen from the above, sewage enters the water collection tank 3 from the water inlet pipe 4, and then the sewage is filtered by the collection net 301, so that larger garbage in the sewage is blocked.

[0030] Example 3: A filter screen 1301 is fixedly connected to the inner side of the filter box 902. A filter cotton layer 1302 is fixedly connected to the bottom of the filter screen 1301. An activated carbon layer 1303 is fixedly connected to the bottom of the filter cotton layer 1302. A clarification layer 1304 is fixedly connected to the bottom of the activated carbon layer 1303.

[0031] As can be seen from the above, through the filtering components inside the filter box 902, the sewage can be filtered and purified, so that the water can meet the discharge standards.

[0032] Example 4: A drain pipe 5 is fixedly connected to one side of the purification main body 2. Support legs 1 are fixedly connected to the four corners of the bottom of the purification main body 2.

[0033] As can be seen from the above, the sewage purification device is placed more stably and is not prone to shaking.

[0034] Example 5: Sludge pumps 1001 are fixedly connected to the interiors of the primary sedimentation tank 10 and the sedimentation tank 12. A sludge pipe 1002 is fixedly connected to one side of the sludge pump 1001.

[0035] As can be seen from the above, the precipitated sludge is pumped by the sludge pump 1001 and conveyed through the sludge pipe 1002 to the sludge tank 901 in the sludge pool 14 for collection.

[0036] Example 6: Packing materials 1101 and aeration pumps 1102 are fixedly connected to the interior of the contact tank 11. An air inlet pipe 1103 is fixedly connected to one side of the aeration pump 1102.

[0037] As can be seen from the above, the aeration pump 1102 can play an oxygen supply role, and the sewage can quickly carry out chemical reactions.

[0038] Example 7: Connecting pipes 16 are fixedly connected through between the primary sedimentation tank 10 and the contact tank 11, between the contact tank 11 and the sedimentation tank 12, between the sedimentation tank 12 and the filtration tank 13, and between the filtration tank 13 and the clear water tank 15.

[0040] Example 8: A cleaning plate 9 is located at the top of the purification main body 2, and the cleaning plate 9 is movably connected to the purification main body 2.

[0041] As can be seen from the above, the cleaning plate 9 can play a role in sealing the top of the purification main body 2 to prevent sewage from flowing out.

[0042] Working principle: When using the sewage purification device for environmental protection, sewage enters the water collection tank 3 from the water inlet pipe 4, and then the sewage is filtered by the collection net 301, so that larger garbage in the sewage is blocked.

Then the water enters the filtration tank 13 through the connecting pipe 16, and the water is filtered and purified by the filter box 902 to meet the discharge standard. Then the water enters the clear water tank 15 through the connecting pipe 16 and is discharged from the drain pipe 5. And the precipitated sludge is pumped by the sludge pump 1001 and transported through the sludge pipe 1002 to the sludge box 901 in the sludge tank 14 to be collected. When cleaning is required, the staff starts the cleaning motor 6. The cleaning motor 6 drives the lifting screw 7 to rotate, and the lifting frame 8 will move downward due to the rotation direction of the lifting screw 7. When the lifting frame 8 drives the cleaning plate 9 to move upward, the sludge box 901 and the filter box 902 under the cleaning plate 9 will move out of the purification main body 2. At this time, the staff can clean the sludge box 901 and the filter box 902, thus completing the use process of the present utility model. The structure of the present utility model is simple, and it is safe and convenient to use.
