Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and more specifically, to a municipal wastewater filtration pretreatment device. Background Technology

[0002] Municipal wastewater typically originates from various discharges in urban life, such as household sewage, industrial wastewater, and rainwater. This wastewater contains a large amount of pollutants, including suspended solids, organic matter, inorganic matter, bacteria, and viruses. If discharged directly into the environment, it will pollute water bodies and affect the ecological balance and human health.

[0003] A search revealed that Chinese Patent Publication No. CN217103358U discloses "a municipal sewage pretreatment device. This utility model separates the sewage treatment area and the water purification area by setting up a sewage tank and a water purification tank, which can better improve the purification treatment of municipal sewage. The sewage tank uses a coarse filter screen to perform the first filtration of municipal sewage. When the municipal sewage after passing through the coarse filter screen enters the filter cylinder, the filter cylinder performs a second filtration, thus achieving a secondary purification effect. The municipal sewage that has passed through the filter cylinder gathers in the sewage tank, where it is purified by sedimentation. On the other hand, the surface portion of the water enters a connecting hole, where a filter cloth, an activated carbon plate, an ion exchange resin layer, and a sponge layer are arranged in sequence to further purify the settled water. The purified water finally enters the water purification tank, thereby further improving the purification effect of municipal sewage." However, the following defects still exist:

[0004] (1) In actual use, municipal sewage contains a large amount of floating matter and debris, which will clog the filtration equipment and affect the filtration efficiency.

[0005] (2) In actual use, sewage may contain large debris, which is inconvenient to break up. Therefore, a municipal sewage filtration pretreatment device is proposed. Utility Model Content

[0030] like Figure 1-5 As shown, this embodiment proposes a municipal sewage filtration pretreatment device, including a treatment chamber 1, a treatment component 2 on the treatment chamber 1, a guide component 3 on one side of the treatment chamber 1, a separation component 4 installed on the guide component 3, a crushing component 5 inside the treatment chamber 1, and a mixing component 6 on the treatment component 2.

[0031] like Figure 3 and Figure 4As shown, the treatment component 2 includes a sewage inlet pipe 201, a sewage outlet pipe 202, a filter mesh 203, a transport pipe 204, a discharge port 205, a first motor 206, and spiral blades 207. The sewage inlet pipe 201 is located at the top of the treatment chamber 1, the sewage outlet pipe 202 is located at the bottom of the treatment chamber 1, the filter mesh 203 is installed inside the treatment chamber 1, multiple transport pipes 204 are installed on one side of the treatment chamber 1 and connected to the treatment chamber 1, the discharge port 205 is located at the end of the transport pipe 204 away from the treatment chamber 1, multiple first motors 206 are installed on the side of the treatment chamber 1 away from the transport pipe 204, and multiple spiral blades... 207 is fixedly connected to the output end of the first motor 206 and rotatably connected between the transport pipe 204 and the treatment chamber 1. During use, sewage enters the treatment chamber 1 through the sewage inlet pipe 201 and flows through the filter mesh 203 into the sewage outlet pipe 202. Impurities contained in the sewage will accumulate on the filter mesh 203. Then, the first motor 206 is started, driving the spiral blades 207 to rotate, so that the impurities on the filter mesh 203 are transported through the spiral blades 207 to the inside of the transport pipe 204. Finally, they are discharged from the transport pipe 204 through the discharge port 205. This can separate solids contained in sewage, which is convenient for subsequent sewage purification treatment.

[0032] like Figure 4 As shown, the guide assembly 3 includes a support plate 301 and a discharge hopper 302. The support plate 301 is fixedly connected to the side of the processing chamber 1 near the transport pipe 204. The discharge port 205 is fixedly connected to the end of the support plate 301 away from the processing chamber 1 and located below the discharge port 205. During use, the discharged debris will fall onto the discharge hopper 302 for guidance and transport, which facilitates subsequent processing.

[0033] like Figure 4 As shown, the separation component 4 includes a separation grid 401, a collection hopper 402, and a separation pipe 403. The separation grid 401 is installed at the bottom of the discharge hopper 302. The collection hopper 402 is fixedly installed at the bottom of the discharge hopper 302 and located below the separation grid 401. One end of the separation pipe 403 is located at the bottom of the collection hopper 402, and the other end is located inside the treatment chamber 1. During use, some of the wastewater contained in the debris on the discharge hopper 302 will drip through the separation grid 401 onto the collection hopper 402 and return to the separation chamber through the separation pipe 403 to await subsequent wastewater treatment.

[0034] like Figure 5As shown, the crushing component 5 includes a second motor 501 and a crushing roller 502. The two second motors 501 are centrally symmetrically installed on both sides of the treatment chamber 1. The two crushing rollers 502 are respectively fixedly connected to the output ends of the two second motors 501 and mesh with each other. When in use, the second motors 501 are started to drive the two crushing rollers 502 to rotate and crush the impurities contained in the sewage. This can prevent the treatment chamber 1 from being blocked by large pieces of impurities and facilitate subsequent dry and wet separation treatment.

[0035] like Figure 5 As shown, the mixing component 6 includes a motor base 601, a third motor 602, a stirring rod 603, and an inlet pipe 604. The motor base 601 is fixedly connected to the sewage outlet pipe 202. The third motor 602 is mounted on the motor base 601. The stirring rod 603 is fixedly connected to the output end of the third motor 602 and rotatably connected to the inside of the sewage outlet pipe 202. The inlet pipe 604 is located on one side of the treatment chamber 1. During use, flocculant is added into the treatment chamber 1 through the inlet pipe 604. Then, the third motor 602 is started to drive the stirring rod 603 to stir the sewage, which can fully mix the flocculant and the sewage, facilitating subsequent sewage purification treatment.

[0036] like Figure 5 As shown, an anti-backflow check valve 7 is installed on the inlet pipe 604. During use, the anti-backflow check valve 7 can prevent sewage from overflowing through the inlet pipe 604.

[0037] like Figure 5 As shown, a reinforcing plate 8 is fixedly connected to the bottom of the support plate 301. The two ends of the reinforcing plate 8 are fixedly connected to the discharge hopper 302 and the processing chamber 1, respectively. When in use, the reinforcing plate 8 can improve the support effect of the support plate 301.

[0038] Specifically, in operation, this municipal wastewater filtration pretreatment device works as follows: wastewater enters the treatment chamber 1 through the wastewater inlet pipe 201. The wastewater flows through the filter mesh 203 into the wastewater outlet pipe 202. Impurities in the wastewater accumulate on the filter mesh 203. Then, the first motor 206 is started, driving the spiral blades 207 to rotate. This allows the impurities on the filter mesh 203 to be transported through the spiral blades 207 into the transport pipe 204. Finally, the impurities are discharged through the discharge port 205 into the transport pipe 204, thus separating the wastewater into wet and dry components and improving the efficiency of subsequent wastewater treatment. The discharged impurities fall onto the discharge hopper 302 for guidance and transport. The wastewater is transported to the treatment chamber 1 for easy subsequent processing. At the same time, some of the wastewater contained in the debris drips through the separation grid 401 onto the collection hopper 402 and returns to the separation chamber through the separation pipe 403 to await subsequent wastewater treatment. The second motor 501 is started to drive the two crushing rollers 502 to rotate and break up the debris in the wastewater, which can prevent the treatment chamber 1 from being blocked by large debris and facilitate subsequent dry and wet separation. Flocculant is added into the treatment chamber 1 through the liquid inlet pipe 604, and then the third motor 602 is started to drive the stirring rod 603 to stir the wastewater, which can fully mix the flocculant and wastewater, facilitating subsequent wastewater purification treatment.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
