Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a horizontal pipe sedimentation and separation device. Background Technology

[0002] Conventional horizontal tube sedimentation separation devices consist of multiple layers of horizontally placed rhomboid sedimentation tubes and sludge-sliding ramps at a 60° angle to the horizontal plane. This divides the vertical water flow section into sedimentation tubes and sludge-sliding ramps with equal settling distances, subdividing the sedimentation and sludge removal functions. When the mixed and flocculated influent flows horizontally through the sedimentation tubes, particles or flocs in the water settle vertically. After contacting the bottom of the sedimentation tubes, they slide down and promptly enter the sludge-sliding ramps through the sludge-sliding ramps, separating from the water flow and entering the sludge zone at the bottom of the sedimentation tank. This process separates the sludge from the water, shortens the settling distance of suspended solids, and improves sedimentation efficiency. However, the conventional horizontal tubes have a rhomboid vertical cross-section, making the manufacturing process relatively complex. They are typically made of stainless steel, resulting in high manufacturing costs and complicated operation. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a horizontal tube sedimentation separation device that is simple in structure, easy to manufacture, and has a good sedimentation effect.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A horizontal pipe sedimentation separation device includes an inlet tank, a sedimentation tank, and an outlet tank arranged sequentially and attached to each other in a front-to-back direction. The inlet tank is provided with an inlet, the outlet tank is provided with an outlet, the inlet tank is provided with a first sludge discharge outlet, the sedimentation tank is provided with a second sludge discharge outlet, and the outlet tank is provided with a third sludge discharge outlet. A sedimentation pipe with a circular cross-section is provided in the sedimentation tank. The two ends of the sedimentation pipe are respectively connected to the inlet tank and the outlet tank. The lower end of the sedimentation pipe is provided with an opening communicating with the sedimentation tank.

[0005] The beneficial effects of the above technical solution are as follows: by using a pipe with a circular cross-section as the sedimentation pipe, it is easy to manufacture. PVC pipes can be purchased directly and opened at the bottom. In addition, by using a circular sedimentation pipe, the required sedimentation depth can be reduced while water flow disturbance is reduced, which is conducive to the settling of suspended solids.

[0006] The lower end of the sedimentation tank in the above technical solution is shaped like a hopper and forms the second sludge discharge port.

[0007] The beneficial effect of the above technical solution is that it enables the sediment in the sedimentation tank to accumulate at the lower inner end of the sedimentation tank and be discharged in a concentrated manner.

[0008] In the above technical solution, the sedimentation tank has multiple mud-sliding plates arranged at intervals along the front-to-back direction at the upper end, and the mud-sliding plates are arranged vertically at an incline and parallel to each other. Between two adjacent mud-sliding plates, multiple sedimentation tubes are arranged vertically at intervals.

[0009] The beneficial effect of the above technical solution is that it enables the area between the mud plate and the outside of the sedimentation pipe to form a static liquid zone, and the settled suspended matter enters the bottom of the sludge tank along the mud plate.

[0010] In the above technical solution, the opening extends to both ends near the sedimentation tank.

[0011] The beneficial effect of the above technical solution is that when the fluid in the sedimentation tube flows axially, the suspended matter carried by the fluid will sink to the opening and enter the sedimentation tank, thereby avoiding the accumulation of sediment in the sedimentation tube.

[0012] In the above technical solution, the water inlet pool is provided with multiple buffer plates arranged vertically in the left-right direction. The multiple buffer plates are arranged at intervals in the front-back direction and are staggered in the left-right direction in the water inlet pool to form a serpentine flow channel. The water inlet is located at one end of the flow channel, and the other end of the flow channel is connected to the sedimentation tank.

[0013] The beneficial effects of the above technical solution are that it allows the sewage in the inlet pool to mix more thoroughly with the flocculant, and at the same time, the flocs in the inlet pool settle more fully.

[0014] The water inlet tank described in the above technical solution is also equipped with a stirring component, which is located in the flow channel near the water inlet.

[0015] The beneficial effect of the above technical solution is that the agitator can stir the wastewater containing flocculant, thereby making the flocculant more evenly dispersed in the wastewater.

[0016] The above technical solution describes a partition in the effluent pool, which divides the effluent pool into two pools whose lower ends are connected. The effluent outlet is connected to one of the pools, and the other pool is connected to the sedimentation pipe.

[0017] The beneficial effect of the above technical solution is that it can prevent sewage entering the effluent pool from being directly discharged through the effluent outlet, thus improving the sedimentation effect of suspended solids in the sewage.

[0018] The above technical solution also includes a moving component and a spray assembly. The moving component is disposed on the sedimentation tank or the effluent tank. The water intake of the spray assembly is located in the effluent tank. The spray assembly is used to spray water into the sedimentation tank. The moving component is used to drive the spray assembly to move left and right.

[0019] The beneficial effects of the above technical solution are as follows: Since the water quality in the effluent tank is better than that in the sedimentation tank, water is drawn from the effluent tank by using moving parts in conjunction with the spray assembly and sprayed into the sedimentation tank. This can flush away the dirt accumulated on the outer wall of the sedimentation pipe and the mud plate. When the spray assembly sprays into the sedimentation tank, it moves laterally, which ensures that each sedimentation pipe and mud plate can be thoroughly rinsed.

[0020] The spray assembly described in the above technical solution includes a water pump, a spray pipe, and a water inlet pipe mounted on the moving part. The spray pipe is horizontally positioned above the sedimentation tank in the front-to-back direction. The inlet of the water pump is connected to the outlet tank through the water inlet pipe. The spray pipe is connected to the outlet of the water pump. Multiple spray holes are spaced apart on the spray pipe along its length.

[0021] The beneficial effect of the above technical solution is that it allows the water inlet pipe to draw water directly from the outlet pool, while the spray pipe sprays water onto the sedimentation pipe in the sedimentation tank.

[0022] The moving parts in the above technical solution include a longitudinal beam, two tracks, and two traveling parts. The two tracks are arranged at both ends of the sedimentation tank in the left-right direction. The two traveling parts correspond one-to-one with the two tracks, and each traveling part is arranged on the corresponding track. The longitudinal beam is arranged above the sedimentation tank in the front-back direction, and both ends of the longitudinal beam are respectively connected to the two traveling parts. The spray pipe is arranged below the longitudinal beam, and the water pump is arranged on the traveling part near the effluent tank.

[0023] The beneficial effect of the above technical solution is that the longitudinal beam can move in the left and right directions under the drive of the two traveling parts, so as to ensure that the spray pipe can spray the entire sedimentation tank. Attached Figure Description

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0027] like Figure 1 , Figure 3 and Figure 5 As shown, this embodiment provides a horizontal pipe sedimentation separation device, including an inlet tank 1, a sedimentation tank 2, and an outlet tank 3 arranged sequentially and attached to each other in a front-to-back direction. The inlet tank 1 is provided with an inlet 11, the outlet tank 3 is provided with an outlet 31, the inlet tank 1 is provided with a first sludge discharge port 12, the sedimentation tank 2 is provided with a second sludge discharge port 21, and the outlet tank 3 is provided with a third sludge discharge port 32. A sedimentation pipe 22 with a circular cross-section is provided in the sedimentation tank 2. The two ends of the sedimentation pipe 22 are respectively connected to the inlet tank 1 and the outlet tank 3. The lower end of the sedimentation pipe 22 is provided with an opening 221 communicating with the sedimentation tank 2. By using a pipe with a circular cross-section as the sedimentation pipe, it is easy to manufacture. It can be obtained by directly purchasing PVC pipe and setting the opening 221 at the lower end. In addition, by using a circular sedimentation pipe, the required sedimentation depth can be reduced while reducing water flow disturbance, which is conducive to the settling of suspended solids. For the cross-section of the sedimentation tube, the arc angle corresponding to the opening can be 30-60°.

[0028] In this embodiment, the inlet tank, sedimentation tank and outlet tank can be integrally formed (e.g., the inlet tank and sedimentation tank and the sedimentation tank and outlet tank are separated by baffles. In this case, the sedimentation pipe is horizontally set in the sedimentation tank, and its two ends pass through the two baffles respectively. At this time, the two ends of the sedimentation pipe can be connected to the inlet tank and the outlet tank respectively).

[0029] like Figures 1-3As shown, in the above technical solution, the lower end of the sedimentation tank 2 is hopper-shaped and forms the second sludge discharge port 21; this allows the sediment in the sedimentation tank to accumulate and be discharged centrally at the lower end of the sedimentation tank. In this embodiment, the lower end of the sedimentation tank can be provided with multiple hopper-shaped openings, and thus multiple second sludge discharge ports can be provided.

[0030] like Figures 3-5 As shown in the above technical solution, the upper end of the sedimentation tank 2 is provided with multiple sliding mud plates 23 arranged at intervals along the front-to-back direction and the left-to-right direction. These sliding mud plates 23 are vertically inclined and parallel to each other. Multiple vertically spaced sedimentation tubes 22 are arranged between adjacent sliding mud plates 23. This allows a static liquid zone to be formed between the sliding mud plates and the outside of the sedimentation tubes, allowing the settled suspended solids to enter the bottom of the sludge tank along the sliding mud plates. In this embodiment, the sliding mud plates can also be smooth plastic plates, and the angle of inclination between the sliding mud plates and the horizontal plane is 60-70°. like Figure 3 and Figure 5 As shown, in the above technical solution, the opening 221 extends to both ends near the sedimentation tank 2; thus, when the fluid in the sedimentation tube flows axially, the suspended matter carried by the fluid will sink to the opening and enter the sedimentation tank, thereby preventing the sediment from accumulating in the sedimentation tube.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, in the above technical solution, the inlet pool 1 is provided with multiple buffer plates 13 arranged vertically in the left-right direction (the multiple buffer plates are distributed at intervals in the front-back direction, one side of each buffer plate is connected to the inner wall of the inlet pool, and two adjacent buffer plates are connected to the inlet pool from different sides). The multiple buffer plates 13 are arranged at intervals in the front-back direction and are staggered in the left-right direction in the inlet pool 1 to form a serpentine flow channel 14. The inlet 11 is located at one end of the flow channel 14, and the other end of the flow channel 14 is connected to the sedimentation tank 2. This allows the sewage in the inlet pool to be mixed more thoroughly with the flocculant, and the flocs in the inlet pool to settle more thoroughly.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the inlet tank 1 in the above technical solution is also provided with a stirring element 15, which is located in the flow channel 14 near the inlet 11; in this way, the stirring element can stir the sewage containing flocculant, thereby making the flocculant more evenly dispersed in the sewage.

[0033] In this embodiment, the stirring component is located at the water inlet (a flocculant can be added near the water inlet in the flow channel), and it includes a motor and a stirring paddle. The motor drives the stirring paddle to rotate, and the stirring paddle is located in the water inlet tank. The motor drives the stirring paddle to rotate to stir the sewage.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, in the above technical solution, a partition 33 is provided inside the effluent tank 3. The partition 33 is used to divide the effluent tank 3 into two tanks 34 whose lower ends are interconnected. The outlet 31 is connected to one of the tanks 34, and the other tank 34 is connected to the sedimentation pipe 22. This prevents sewage entering the effluent tank from being directly discharged through the outlet, thus improving the sedimentation effect of suspended solids in the sewage. The partition is arranged in the left-right direction, and both sides are connected to the side walls of the effluent tank. There is a gap between the lower end of the partition and the inner bottom wall of the effluent tank so that the two tanks are interconnected.

[0035] like Figure 2 , Figure 4 and Figure 6 As shown, the above technical solution also includes a moving component 4 and a spray assembly 5. The moving component 4 is installed on the sedimentation tank 2 or the effluent tank 3. The water intake of the spray assembly 5 is located in the effluent tank 3. The spray assembly 5 is used to spray water into the sedimentation tank 2. The moving component 4 is used to drive the spray assembly 5 to move left and right. Since the water quality in the effluent tank is better than that in the sedimentation tank, by using the moving component in conjunction with the spray assembly to draw water from the effluent tank and spray it into the sedimentation tank, the dirt accumulated on the outer wall of the sedimentation pipe and the mud plate can be flushed and removed. When spraying into the sedimentation tank, the spray assembly moves laterally, which ensures that each sedimentation pipe and mud plate can be thoroughly rinsed.

[0036] like Figure 2 and Figure 4As shown, the spray assembly 5 in the above technical solution includes a water pump 51, a spray pipe 52, and a water inlet pipe 53 mounted on the moving part 4. The spray pipe 52 is horizontally positioned above the sedimentation tank 2 along the front-to-back direction. The inlet of the water pump 51 is connected to the outlet tank 3 through the water inlet pipe 53, and the spray pipe 52 is connected to the outlet of the water pump 51. Multiple spray holes 521 are spaced along the length of the spray pipe 52. This allows the water inlet pipe to draw water directly from the outlet tank, while the spray pipe sprays water onto the sedimentation pipes in the sedimentation tank. The moving part 4 includes a longitudinal beam 41, two tracks 42, and two traveling sections. 43. Two tracks 42 are arranged at both ends of the sedimentation tank 2 in the left-right direction. Two traveling parts 43 correspond one-to-one with the two tracks 42. Each traveling part 43 is arranged on the corresponding track 42. The longitudinal beam 41 is arranged above the sedimentation tank 2 in the front-back direction, and the two ends of the longitudinal beam 41 are respectively connected to the two traveling parts 43. The spray pipe 52 is arranged below the longitudinal beam 41. The water pump 51 is arranged on the traveling part 43 near the effluent tank 3. In this way, the longitudinal beam can move in the left-right direction under the drive of the two traveling parts to ensure that the spray pipe can spray the entire sedimentation tank.

[0037] The water inlet pipe 53 can draw water from a pool body equipped with a water outlet, and the water inlet pipe can be a flexible steel wire hose that is resistant to bending.

[0038] In this embodiment, the structure of the slide rail, traveling section and longitudinal beam is similar to that of a gantry crane, while the water pump 51 is located at one end of the moving part and moves horizontally left and right with the corresponding traveling section.

[0039] In this embodiment, the water outlet is located at the upper end of the side wall of the water outlet pool, while the water inlet is located at the upper end of the side wall of the water inlet, and the two can be at the same height.

[0040] In this embodiment, after the wastewater enters the inlet tank, it is first mixed with the flocculant, and then flows along the flow channel until it enters the sedimentation tank through the sedimentation pipe, and finally enters the outlet tank. When the water level in the entire horizontal pipe sedimentation separation device reaches the state of inlet and outlet balance, the water flows smoothly into the outlet tank through the sedimentation pipe in the inlet tank, and the sediment in the water is fully separated and settles in the sedimentation pipe.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
