Description

Technical Field

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

[0002] With the acceleration of the urbanization process and the improvement of the industrialization level, the urban sewage discharge has increased significantly, bringing great pressure to the environment. Harmful substances in sewage, such as large particulate impurities, heavy metals, organic matter, bacteria and viruses, if directly discharged without effective treatment, will cause serious pollution and damage to water bodies, soil and ecosystems, and thus affect human health and sustainable development. Although existing treatment devices can treat sewage to a certain extent, there are certain defects in the treatment process. For example, in a Chinese patent with the publication number of "CN217829070U", a sewage treatment device for environmental protection projects is disclosed, which includes a treatment tank. The top of the treatment tank is fixedly installed with a motor through an auxiliary rod. The output end of the motor is fixedly installed with a rotating shaft. The outer surface of the rotating shaft is fixedly installed with a fixing plate. The top and bottom of the fixing plate are both fixedly installed with a plurality of connecting rods. The outer surface of the rotating shaft near the bottom is equidistantly installed with a plurality of crushing knives. The front surface of the treatment tank is installed with a sealing cover through a plurality of screws. The rear surface of the sealing cover is fixedly installed with a sealing ring. One end of the rotating shaft movably penetrates into the interior of the treatment tank, and the other end of the rotating shaft is movably embedded in the bottom of the interior of the treatment tank. One side of the interior of the treatment tank near the bottom is fixedly installed with a reinforcing plate, and a chute is opened at the top of the reinforcing plate. A filter plate is movably embedded in the interior of the chute. The top of the treatment tank near the left side is fixedly communicated with a water inlet pipe. When the above device filters sewage, the sewage is filtered by the filter plate. Therefore, as the use time increases, the filtering structure will gradually be blocked. Therefore, it is necessary to regularly stop the device for cleaning, and it is impossible to clean the filtering structure synchronously when filtering sewage. The cleaning difficulty is high and the cleaning efficiency is low. Content of the Utility Model

[0003] The purpose of the utility model is to provide a sewage treatment device for environmental protection projects to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A sewage treatment device for environmental protection projects includes a container part. The bottom of the container part is fixedly connected with a drain pipe. A filter pipe and a scraping plate are arranged inside the container part. A filter pipe communicating with a hollow cavity is formed inside the filter pipe. A water storage cavity for accommodating sewage is formed between the interior of the container part and the outer wall of the filter pipe. The scraping plate is rotatably connected to the interior of the water storage cavity, and one side of the scraping plate is in contact with the outer peripheral surface of the filter pipe. The drain pipe is communicated with a drainage cavity, and a conveying channel for conveying sewage along a preset path is formed among the water storage cavity, the drainage cavity and the drain pipe.

[0005] Preferably, a sewage discharge pipe is fixedly connected to the bottom of the container part. The sewage discharge pipe is communicated with the water storage cavity, and a second valve is installed on the sewage discharge pipe, and a first valve is installed on the drain pipe.

[0006] Preferably, the container part includes a barrel body. A detachable top cover is screwed to the top of the barrel body, and a water inlet pipe for adding sewage is fixedly connected to the top of the top cover. The water inlet pipe is communicated with the water storage cavity.

[0007] Preferably, the scraper is rotatably connected to the bottom of the top cover, and a motor is fixedly connected to the top of the top cover. The motor is on one side of the water inlet pipe, and the output end of the motor is connected to a connecting shaft. One end of the connecting shaft is connected to the scraper.

[0008] Preferably, a water adding hopper is fixedly connected to the top of the water inlet pipe. The water adding hopper is internally communicated with the water inlet pipe.

[0009] Preferably, a material guiding slope is formed in the water storage cavity slanting downward from the inner wall to the bottom.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] (1) When the present utility model filters sewage through the filter pipe, the scraper rotates synchronously relative to the filter pipe, so that the scraper scrapes the peripheral surface of the filter pipe, and then pushes the large-particle impurities on the outer peripheral surface of the filter pipe, avoiding the blockage of the filter pipe by large-particle impurities and preventing the filter pipe from being gradually blocked. Therefore, there is no need to regularly stop the device for cleaning, and the cleaning can be carried out synchronously during the sewage filtration process, with low cleaning difficulty and high cleaning efficiency.

[0012] (2) When the user needs to discharge the large-particle impurities inside the device, by opening the second valve on the sewage discharge pipe, the scraper pushes the large-particle impurities inside the water storage cavity, so that the large-particle impurities are discharged through the sewage discharge pipe, making it convenient to clean the large-particle impurities inside the device, further reducing the cleaning difficulty of the device and further improving the cleaning efficiency of the device.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 6 As shown, the present utility model provides the following technical solutions:

[0022] An environmental protection engineering sewage treatment device includes a container member. A drain pipe 2 is fixedly connected to the bottom of the container member, and a filter pipe 9 and a scraper 7 are arranged inside the container member. A filter pipe 9 is formed inside the filter pipe 9 and is communicated with a hollow cavity. A water storage cavity 8 for accommodating sewage is formed between the inside of the container member and the outer wall of the filter pipe 9. The scraper 7 is rotatably connected to the inside of the water storage cavity 8, and one side of the scraper 7 is in contact with the outer peripheral surface of the filter pipe 9. The drain pipe 2 is communicated with the drainage cavity 15, and a conveying channel for conveying sewage along a preset path is formed among the water storage cavity 8, the drainage cavity 15 and the drain pipe 2.

[0023] Through the above technical solutions, when sewage needs to be treated, the sewage to be treated is added to the water storage cavity 8 inside the container member. After the sewage is added to the water storage cavity 8, the sewage is filtered by the filter pipe 9, thereby blocking large particle impurities in the sewage and making the large particle impurities stay in the water storage cavity 8. The filtered sewage passes through the filter pipe 9 and enters the drainage cavity 15. When the filter pipe 9 filters the sewage, the scraper 7 rotates inside the water storage cavity 8, so that the scraper 7 scrapes the outer peripheral surface of the filter pipe 9, preventing the large particle impurities from stacking at one place and causing the filter pipe 9 to be blocked. The sewage is guided by the drainage cavity 15 and discharged through the drain pipe 2.

[0024] In order to facilitate the discharge of sundries inside the container member, in the present utility model, as Figures 1 - 6 shown, a sewage discharge pipe 6 is also fixedly connected to the bottom of the container member. The sewage discharge pipe 6 is communicated with the water storage cavity 8, and a second valve 11 is installed on the sewage discharge pipe 6, and a first valve 10 is installed on the drain pipe 2.

[0025] In this embodiment, when the scraper 7 pushes large particulate impurities, the second valve 11 is opened, and the large particulate impurities are discharged through the sewage discharge pipe 6. When the personnel do not need to discharge sewage, the first valve 10 is closed, and when it is necessary to discharge the filtered sewage, the first valve 10 is opened.

[0026] Specifically, in one embodiment, regarding the above-mentioned container part:

[0027] As Figures 1 - 6 shown, the container part includes a barrel body 1, the top of the barrel body 1 is screwed and connected with a detachable top cover 3, and a water inlet pipe 13 for adding sewage is fixedly connected to the top of the top cover 3, and the water inlet pipe 13 communicates with the water storage cavity 8;

[0028] The top of the water inlet pipe 13 is fixedly connected with a water filling hopper 5, and the water filling hopper 5 communicates with the inside of the water inlet pipe 13.

[0029] In this embodiment, when sewage needs to be added, the sewage is added to the water filling hopper 5, the sewage is guided into the inside of the water inlet pipe 13 through the water filling hopper 5, and the sewage is guided through the water inlet pipe 13 and conveyed into the water storage cavity 8.

[0030] In addition, in the present utility model, regarding the installation position of the scraper 7, as Figure 3 、 Figure 4 and Figure 6 shown, the scraper 7 is rotatably connected to the bottom of the top cover 3, and a motor 4 is fixedly connected to the top of the top cover 3. The motor 4 is on one side of the water inlet pipe 13, and the output end of the motor 4 is connected with a connecting shaft 14, and one end of the connecting shaft 14 is connected with the scraper 7.

[0031] In this embodiment, when it is necessary to drive the scraper 7 to rotate, the motor 4 works, and then the motor 4 drives the connecting shaft 14 to rotate. The connecting shaft 14 drives the scraper 7 to rotate, and then the scraper 7 scrapes the peripheral surface of the filter pipe 9. The large particulate impurities are pushed by the scraper 7, so that the large particulate impurities are discharged through the sewage discharge pipe 6.

[0032] When the device discharges impurities, in order to improve the impurity discharge efficiency, as Figures 1 - 2 、 Figure 6 shown, a material guiding slope 12 is formed in the water storage cavity 8 slanting downward from the inner wall to the bottom.

[0033] In this embodiment, when the device discharges large particulate impurities, with the cooperation of the material guiding slope 12, the large particulate impurities can be discharged from the sewage discharge pipe 6 faster.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
