Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an automatic cleaning and filtration device for water treatment. Background Technology

[0002] Water treatment and wastewater removal refers to the separate treatment of highly polluted water and unpolluted or low-polluted water to reduce the amount of pollutants discharged and lower water treatment costs. Through intelligent diversion, precise interception and other technical means, wastewater can be fully collected to ensure urban flood control and drainage safety and restore the ecological function of natural water bodies. The aim is to remove suspended solids, organic pollutants and recalcitrant substances from the water so that the water quality meets the discharge standards or reuse requirements.

[0003] A search revealed that the document with publication number "CN218306378U" mentions "This utility model discloses an automatic multi-stage water treatment filtration device, including a base plate, a stirring mechanism, and a filtration mechanism. A water pump is fixedly installed in the middle of the top surface of the base plate. A first connecting pipe is fixedly connected to the left end of the water pump, and a stirring mechanism is fixedly connected to the other end of the first connecting pipe. The stirring mechanism includes a tank, a fixed plate, a protective cone box, a drive motor, a connecting shaft, a stirring rod, and a support plate. The tank is fixedly connected to the other end of the first connecting pipe. A fixed plate is fixedly installed on the upper end of the inner wall of the tank. A protective cone box is fixedly installed in the middle of the fixed plate, and a drive motor is fixedly installed on the top of the inner wall of the protective cone box." During use, it... The conical box in the tank divides the water to be treated into streams. The drive motor is started to rotate the connecting shaft, which in turn drives the stirring rod to stir and cut the water in the tank. This effectively prevents impurities in the water from clogging the pipes. However, in traditional wastewater treatment, a combination of physical sedimentation and chemical treatment is usually used to remove impurities and pollutants from the water. However, this method has problems such as low efficiency, complex operation, and high maintenance costs. Especially when treating wastewater containing fine particles and light impurities such as hair, traditional filtration equipment often needs to be cleaned manually frequently due to clogging. This not only increases labor intensity but also affects the continuous operation efficiency of the entire water treatment system.

[0004] To address these issues, we provide an automatic cleaning and filtration device for water treatment. Utility Model Content

[0005] The purpose of this invention is to provide an automatic cleaning and filtration device for water treatment, which solves the problems mentioned in the background art.

[0006] This application provides an automatic cleaning and filtration device for water treatment, including an impurity cleaning tank and a debris cleaning assembly. The debris cleaning assembly includes a leakage trough disposed inside the impurity cleaning tank, a steel mesh drum installed inside the leakage trough, a rotary motor installed on the upper middle side of the steel mesh drum, a felt-wrapped cloth tube installed in the middle of the inner side of the steel mesh drum, cutters provided on the outer sides of the felt-wrapped cloth tube, a driven bearing provided on the lower side of the felt-wrapped cloth tube, and a liquid pump installed on the lower side of the impurity cleaning tank. A collection water pipe is welded to the end of the liquid pump.

[0007] Preferably, the steel mesh drum and the impurity cleaning tank are coaxially centered, and a leakage groove is provided in the gap between the steel mesh drum and the impurity cleaning tank. The steel mesh drum and the impurity cleaning tank form a lint filtration structure through the leakage groove.

[0008] Preferably, the felt-covered tube and the steel mesh tube are arranged concentrically, and the felt-covered tube is a steel cylinder with adhesive felt wrapped around its surface.

[0009] Preferably, the cutter and the felt-wrapping tube are evenly distributed around the central axis, and the cutter and the felt-wrapping tube form a stable rotating structure through a rotary motor and a driven bearing.

[0010] Preferably, the liquid pump and the impurity cleaning tank are arranged symmetrically in two groups, left and right, and the ends of the two groups of liquid pumps are connected to a water collection pipe.

[0011] Preferably, a filter tank is welded to the end of the main water pipe, and multiple filter plates are connected to the inner side of the filter tank by slots.

[0012] Preferably, the right-side pipe of the filter water tank is connected to a flocculation sedimentation tank, the right side of the flocculation sedimentation tank is welded with a liquid delivery pump, and the end pipe of the liquid delivery pump is connected to an activated carbon filter.

[0013] As can be seen from the above technical solution, this application provides an automatic cleaning and filtration device for water treatment. In use, wastewater filtered for large impurities is first poured into the steel mesh drum in the middle of the impurity cleaning tank through the inlet. At this time, a rotating motor drives the felt-covered cloth drum and the cutter to rotate along the driven bearing, adsorbing hair and various fine impurities in the water onto the felt-covered cloth drum. Due to gravity, the wastewater flows through the steel mesh drum into the leakage tank. During this process, any remaining hair is adsorbed onto the steel mesh drum, and the cutter removes the hair. The process involves chopping the hair to reduce clogging in the steel mesh tank and simplifying subsequent cleaning by reducing its size. A pump then pumps the filtered wastewater through a mains pipe into the filter tank. After passing through four different multi-stage filter plates that capture solid hair and particles, the wastewater flows into a flocculation and sedimentation tank. Flocculant is then added to flocculate and settle the microparticles. Finally, a pump delivers the flocculated wastewater to an activated carbon filter for further filtration before discharge. This completes the process of using an automatic cleaning and filtration device for water treatment.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Wastewater enters the steel mesh drum through the inlet on the impurity cleaning tank. Due to its own weight, the water seeps from the steel mesh drum into the leakage tank, and is then pumped away by the pump through the gap between the leakage tank and the bottom of the steel mesh drum. This filters out small impurities and hair from the wastewater. Some hair and debris are carried by the water flow and are absorbed by the felt cloth tube, thus reducing the filtration pressure of the steel mesh drum. As the steel mesh drum filters, the rotating motor drives the felt cloth tube and the cutter to rotate in conjunction with the driven bearing. The blade of the cutter is in close contact with the steel mesh drum, cutting off the hair and impurities wrapped around the steel mesh drum and preventing the holes of the steel mesh drum from becoming clogged. The rotation of the felt cloth tube also improves its ability to wrap impurities and hair.

[0016] 2. Two sets of pumps can promptly discharge the filtered wastewater, improving drainage efficiency. After the wastewater is sent into the filtration tank, the first two sets of the four multi-stage filter plates are made of carbon steel, which has high compressive strength and corrosion resistance, and is suitable for capturing dirt of 1-10 mm. The latter two sets are made of PP filter plates, which have high stability and high dirt capture accuracy. The flocculant is poured into the flocculation sedimentation tank. After sedimentation, the pumps extract the flocculated wastewater from the flocculation sedimentation tank and send it into the activated carbon filter, thereby capturing and filtering the fine impurities and bacteria in the wastewater, achieving the final fine filtration effect.

[0017] In summary, this application can reduce the clogging of wastewater by repeatedly adsorbing and capturing hair and various impurities in the wastewater, thereby improving the cleaning effect. Attached Figure Description

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] See Figure 1-5 An automatic cleaning and filtration device for water treatment includes an impurity cleaning tank 1 and a debris cleaning assembly 2. The debris cleaning assembly 2 includes a leakage trough 201 disposed inside the impurity cleaning tank 1. A steel mesh barrel 202 is installed inside the leakage trough 201. A rotary motor 203 is installed on the upper middle side of the steel mesh barrel 202. A felt-wrapped cloth tube 204 is installed in the middle of the inner side of the steel mesh barrel 202. Cutters 205 are provided on the outer side of the felt-wrapped cloth tube 204. A driven bearing 206 is provided on the lower side of the felt-wrapped cloth tube 204. A liquid pump 207 is installed on the lower side of the impurity cleaning tank 1. A collection water pipe 208 is welded to the end of the liquid pump 207.

[0027] In this invention, the steel mesh bucket 202 and the impurity cleaning tank 1 are coaxially centered. A leakage groove 201 is provided in the gap between the steel mesh bucket 202 and the impurity cleaning tank 1. The steel mesh bucket 202 and the impurity cleaning tank 1 form a lint filter structure through the leakage groove 201. When needed, sewage enters the steel mesh bucket 202 from the inlet on the impurity cleaning tank 1. Due to its own weight, the water will seep from the steel mesh bucket 202 into the leakage groove 201, and then be pumped away by the pump 207 from the bottom gap between the leakage groove 201 and the steel mesh bucket 202, thereby filtering out small impurities and hair in the sewage.

[0028] In this invention, the felt-covered cloth cylinder 204 and the steel mesh cylinder 202 are arranged concentrically. The felt-covered cloth cylinder 204 is a steel cylinder with adhesive felt cloth wrapped around its surface. When it is needed, some hair and debris will be adsorbed by the felt-covered cloth cylinder 204 as the water flows, thereby reducing the filtration pressure of the steel mesh cylinder 202.

[0029] In this invention, the cutter 205 and the felt-wrapped cloth tube 204 are evenly distributed around the central axis. The cutter 205 and the felt-wrapped cloth tube 204 form a stable rotating structure through the rotary motor 203 and the driven bearing 206. As the steel mesh barrel 202 filters, the rotary motor 203 drives the felt-wrapped cloth tube 204 and the cutter 205 to rotate in conjunction with the driven bearing 206. The blade of the cutter 205 is tightly fitted with the steel mesh barrel 202, thereby cutting off the hair and impurities wrapped around the steel mesh barrel 202 and preventing the holes of the steel mesh barrel 202 from becoming clogged. The rotation of the felt-wrapped cloth tube 204 also improves its ability to wrap impurities and hair.

[0030] In this invention, the liquid pump 207 and the impurity cleaning tank 1 are arranged symmetrically in two groups on the left and right. The ends of the two groups of liquid pumps 207 are connected to a water collection pipe 208. When needed, the two groups of liquid pumps 207 can discharge the filtered sewage in time, thereby improving drainage efficiency.

[0031] In this utility model, a filter water tank 3 is welded to the end of the main water pipe 208. Multiple filter plates 4 are connected to the inner side of the filter water tank 3 by slots. When needed, the first two sets of the four sets of multiple filter plates 4 are made of carbon steel filter plates, which have high compressive strength, corrosion resistance and are suitable for capturing dirt of 1-10 mm. The latter two sets are made of PP filter plates, which have high stability and high dirt capture accuracy.

[0032] In this invention, a flocculation sedimentation tank 5 is connected to the right side of the filter tank 3 via a pipe. A liquid delivery pump 6 is welded to the right side of the flocculation sedimentation tank 5. An activated carbon filter 7 is connected to the end pipe of the liquid delivery pump 6. When needed, the flocculant is poured into the flocculation sedimentation tank 5. After sedimentation, the liquid delivery pump 6 draws the treated wastewater from the flocculation sedimentation tank 5 and sends it into the activated carbon filter 7, thereby capturing and filtering the fine impurities and bacteria in the wastewater, achieving the final fine filtration effect.

[0033] As can be seen from the above technical solution, during use, the wastewater after being filtered for large impurities is first poured into the steel mesh drum 202 in the middle of the impurity cleaning tank 1 through the inlet. At this time, the rotary motor 203 drives the felt cloth drum 204 and the cutter 205 to rotate along the driven bearing 206, adsorbing the hair and various fine impurities in the water onto the felt cloth drum 204. Due to gravity, the wastewater will flow through the steel mesh drum 202 into the leakage tank 201. During this process, the remaining hair will be adsorbed onto the steel mesh drum 202, and the cutter 205 will chop the hair. To reduce clogging of the steel mesh drum 202 and facilitate subsequent cleaning by reducing the volume of hair, the pump 207 then pumps the filtered wastewater into the filter tank 3 through the collection pipe 208. After passing through four different multi-stage filter plates 4 to capture solid hair and particles in the wastewater, it flows into the flocculation sedimentation tank 5. Then, a flocculant is added to flocculate and precipitate the microparticles in the wastewater. Finally, the pump 6 sends the flocculated wastewater into the activated carbon filter 7 for filtration before it is discharged. This completes the process of using an automatic cleaning and filtration device for water treatment.
