Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater treatment impurity removal device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life. During wastewater treatment, many impurities in the wastewater require multiple filtration and sedimentation processes before subsequent aeration tanks and other more demanding biological treatment procedures. During filtration, impurities need continuous removal, but existing impurity removal equipment suffers from inconvenient internal cleaning and maintenance, and impurities easily accumulate and cause blockages, thus affecting the efficiency of impurity removal.

[0003] Currently, there are many filtration devices on the market, such as the wastewater treatment impurity cleaning device proposed in CN223351112U, which includes a base, two support frames fixedly installed on the top of the base, a tank fixedly sleeved inside the two support frames, an inlet pipe connected to one end of the tank, a flange ring fixedly sleeved on the outer side of the tank away from the inlet pipe, a flange plate movably installed on the outer side of the flange ring, an outlet pipe fixedly sleeved inside the flange plate, and flange rings fixedly installed at opposite ends of the outlet pipe and the inlet pipe.

[0004] Existing wastewater treatment impurity removal equipment mostly uses direct sedimentation during the sedimentation process. In large water flows, most of the sediment cannot be fully settled and is easily carried away by the water flow, thus affecting the wastewater treatment effect and having certain limitations. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment impurity cleaning device to solve the problem mentioned in the background art that existing wastewater treatment impurity cleaning devices have a large water flow during sedimentation, which easily carries away some sediment and affects the filtration effect. This device removes larger particles and floating matter by pre-filtering the influent. After the water flows out through the filter cylinder, it passes through the slow-flow truncated cone and is guided to the slow-flow tank. The two slow-flow processes greatly reduce the water flow speed, thereby allowing for sufficient sedimentation. Compared with traditional purification equipment, this device has significant advantages.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment impurity cleaning device, comprising a purification tank, an outlet fixedly provided on one side of the upper end of the purification tank, an inlet fixedly provided on the other side of the upper end of the purification tank, a top cover fixedly connected to the upper end of the purification tank via a flange thread, a filter cylinder fixedly connected to the top cover, a first slow-flow frustum fixedly connected below the filter cylinder, a first slow-flow groove fixedly connected below the first slow-flow frustum, and a sedimentation zone provided at the lower end of the interior of the purification tank.

[0007] Preferably, a lower cover plate is fixedly connected to one end of the water inlet, and the lower cover plate is sleeved on the bottom of the filter cylinder.

[0008] Preferably, a connecting bracket is fixedly connected to both ends of one side of the purification tank, and a fixed base plate is fixedly connected to one end of the connecting bracket. Threaded fixing holes are fixedly opened at the four corners of the fixed base plate.

[0009] Preferably, an observation window is fixedly provided on one side of the purification tank, and a sewage pump is fixedly connected to the bottom of the interior of the purification tank, with the sewage outlet of the sewage pump connected to a sewage pipe.

[0010] Preferably, a drain valve is fixedly connected to one end of the drain pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model can slow down the flow rate of sewage, allowing the sediment in the sewage to settle fully, avoiding the effect of excessively fast water flow on sediment formation, and thus achieving a good sedimentation effect.

[0012] 2. This utility model can extract and discharge sediment without manual removal. Compared with traditional manual dredging, the sediment extraction and discharge effect is better and more convenient without disassembly. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a wastewater treatment impurity cleaning device, including a purification tank 1, an outlet 2 fixedly provided on one side of the upper end of the purification tank 1, an inlet 3 fixedly provided on the other side of the upper end of the purification tank 1, an upper cover 5 fixedly connected to the upper end of the purification tank 1 by a flange 4, a filter cylinder 6 fixedly connected to the upper cover 5, a first slow-flow frustum 8 fixedly connected to the lower part of the filter cylinder 6, a first slow-flow groove 9 fixedly connected to the lower part of the first slow-flow frustum 8, and a sedimentation zone provided at the lower end of the interior of the purification tank 1.

[0017] In this embodiment, wastewater can be introduced into the purification tank 1 through the inlet 3. After entering the filter cylinder 6, the wastewater can flow out for filtration. The water flowing out of the filter cylinder 6 can be guided to the outer surface of the first slow-flow truncated cone 8 to diffuse in all directions, thus slowing down the flow. The diffused wastewater is guided to the inner wall of the first slow-flow trough 9, where the diffused water flow is concentrated and guided again, thereby completing the slow-flow effect. The slow-flowing water flows to the bottom of the purification tank 1 for sedimentation. The overflow water can flow out from the outlet 2, thus completing the wastewater purification. This design can slow down the flow rate of wastewater, allowing the sediment in the wastewater to settle fully, avoiding the influence of excessively fast water flow on sediment formation, and has a very good sedimentation effect.

[0018] Specifically, a lower cover plate 7 is fixedly connected to one end of the water inlet 3, and the lower cover plate 7 is sleeved on the bottom of the filter cylinder 6.

[0019] In this embodiment, the lower cover plate 7 is sleeved on the bottom of the filter cylinder 6, which allows the water to be filtered through the filter cylinder 6. When the filter cylinder 6 needs to be cleaned, the upper cover 5 can be unscrewed, and the upper cover 5 and the filter cylinder 6 can be taken out as a whole, thereby completing the cleaning of the filter cylinder 6.

[0020] Specifically, a connecting bracket 16 is fixedly connected to both ends of one side of the purification tank 1, and a fixed base plate 17 is fixedly connected to one end of the connecting bracket 16. Threaded fixing holes 18 are fixedly opened at the four corners of the fixed base plate 17.

[0021] In this embodiment, the entire structure can be fixed by the fixed base plate 17.

[0022] Specifically, an observation window 10 is fixedly opened on one side of the purification tank 1, and a sewage pump 11 is fixedly connected to the bottom of the interior of the purification tank 1. The sewage outlet of the sewage pump 11 is connected to a sewage pipe 12.

[0023] In this embodiment, the sediment in the sedimentation zone inside the purification tank 1 can be observed through the observation window 10. When the sediment exceeds a certain amount, the control switch of the sewage pump 11 can be turned on, so that the sewage pump 11 can extract the sediment and discharge it through the sewage pipe 12. The sewage pump 11 can be powered by an external power source. This design method can extract and discharge the sediment without manual cleaning. Compared with traditional manual sludge removal, the sediment extraction and discharge effect is better and more convenient without disassembly.

[0024] Specifically, a drain valve 13 is fixedly connected to one end of the drain pipe 12.

[0025] In this embodiment, the drain valve 13 can be closed to prevent backflow. During use, wastewater can be introduced into the purification tank 1 through the inlet 3. After entering the filter cylinder 6, the wastewater can flow out for filtration. The water flowing out of the filter cylinder 6 can be guided to the outer surface of the first slow-flow truncated cone 8 to diffuse in all directions, thus slowing down the flow. The diffused wastewater is guided to the inner wall of the first slow-flow trough 9, where the diffused water flow is concentrated again for guidance, thereby completing the slow-flow effect. The slow-flowing water flows to the bottom of the purification tank 1 for sedimentation and overflow. Water can flow out from outlet 2, thus completing the sewage purification. The lower cover 7 is fitted onto the bottom of the filter cylinder 6, allowing the water to pass through the filter cylinder 6 for filtration. When the filter cylinder 6 needs cleaning, the upper cover 5 can be unscrewed, and the entire assembly of the upper cover 5 and the filter cylinder 6 can be removed to complete the cleaning of the filter cylinder 6. The sediment in the sedimentation zone inside the purification tank 1 can be observed through the observation window 10. When the sediment exceeds a certain amount, the control switch of the sewage pump 11 can be turned on, allowing the sewage pump 11 to extract the sediment and discharge it through the sewage pipe 12.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
