Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically relating to a circulating wastewater three-dimensional treatment 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, medical care, and catering, and is increasingly becoming a part of ordinary people's daily lives.

[0003] In existing technologies, in order to improve the purification effect of sewage, the relevant purification equipment is often used to treat sewage multiple times using a circulation structure. However, most sewage treatment equipment is a closed integrated structure. After the filter screen has been used for sewage treatment for a long time, a lot of impurities will remain on the filter screen, which will affect the purification effect of the sewage treatment equipment. Moreover, the disassembly and replacement of the filter screen by the staff is also a relatively complicated task, which is time-consuming, labor-intensive and impractical. Summary of the Invention

[0004] This invention provides a circulating three-dimensional sewage treatment device, which aims to solve the problem of poor practicality of existing sewage treatment equipment due to the time-consuming and labor-intensive work of cleaning the filter screen.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a circulating wastewater three-dimensional treatment device, comprising:

[0006] The tank has an open inner groove at the top and an annular groove outside the inner groove. The annular groove has two parallel and spaced-apart straight sections. The tank is provided with an inlet pipe and an outlet pipe that communicate with the inner groove.

[0007] A filter structure is installed in the inner tank. The filter structure has multiple filter sections and is used to filter impurities in wastewater.

[0008] A cleaning component, located above the housing, is used to clean the filter section;

[0009] A linkage adjustment group is installed on the housing and is poweredly connected to the filter structure and the cleaning component, respectively. It is used to enable the cleaning component to clean each filter section one by one during the process of the filter structure filtering the liquid in the inner tank.

[0010] In one possible implementation, the filtering structure includes:

[0011] A connecting shaft is rotatably mounted on the housing. The connecting shaft is connected to four filter plates, each of which is arranged in a ring around the axis of the connecting shaft and extends radially along the connecting shaft.

[0012] Each filter plate is a filter section.

[0013] The inner groove is a semi-circular groove with a circumferential surface corresponding to the protruding end of each filter plate, and the axis of the inner groove is collinear with the axis of the connecting shaft.

[0014] In one possible implementation, the cleaning component includes:

[0015] A reciprocating lead screw is rotatably mounted on the top of the housing in a horizontal direction perpendicular to the axis of the connecting shaft, and is also mounted along the axis of the connecting shaft. Both ends of the reciprocating lead screw are provided with bidirectional threads.

[0016] Two mounting blocks are provided, located at opposite ends of the housing along the length of the reciprocating screw and slidably connected to the housing. Each mounting block is helically connected to both ends of the reciprocating screw. Each mounting block has a mounting shaft slidably connected to it, with the axis of the mounting shaft perpendicular to the axis of the reciprocating screw. A sleeve is rotatably mounted on the mounting shaft, and the outer wall of the sleeve is evenly distributed with several brushes. An adjusting gear is provided at one end of the sleeve.

[0017] The mounting part is located at the end of the mounting shaft away from the adjusting gear, and the mounting part is provided with a connecting rod, one end of which is slidably engaged with the annular groove;

[0018] A rack is fixedly installed on the top of the housing, and its length direction is set along the length direction of the reciprocating lead screw. The rack is used to engage with the adjusting gear after the mounting shaft drives the sleeve to move.

[0019] In one possible implementation, the linkage adjustment component includes:

[0020] A reversing shaft is rotatably mounted on the top of the housing and is perpendicular to the reciprocating screw. One end of the reversing shaft is fixedly connected to a transmission wheel, and the other end of the reversing shaft is fixedly connected to a transmission gear.

[0021] The second transmission gear is fixedly mounted on the reciprocating lead screw and meshes with the first transmission gear;

[0022] A power shaft is rotatably mounted outside the housing. An active dial and a second transmission wheel are connected to the power shaft. The first transmission wheel and the second transmission wheel are connected by a transmission component.

[0023] The driven grooved wheel is fixedly mounted at one end of the connecting shaft. The driven grooved wheel has four elongated notches that are actuated one by one by levers mounted on the active dial.

[0024] In one possible implementation, the end of the connecting rod that extends into the annular groove has a spherical portion.

[0025] In one possible implementation, both the adjusting gear and the rack have helical teeth.

[0026] In one possible implementation, all the brushes are in an arc shape.

[0027] In this implementation, the linkage adjustment component simultaneously coordinates the filter structure and the cleaning component, ensuring that each filter element in the filter structure corresponds to the cleaning component and is cleaned by it. This allows for the cleaning of each filter element without shutting down the machine, improving the filtration effect of the filter structure and reducing the workload of staff to a certain extent, making it highly practical.

Detailed Implementation

[0037] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0038] Please refer to the following: Figures 1 to 7 The circulating wastewater three-dimensional treatment equipment provided by the present invention will now be described. The circulating wastewater three-dimensional treatment equipment includes a housing 1, a filter structure 2, a cleaning component 3, and a linkage adjustment group 4. The housing 1 has an open inner tank 11 at its top and an annular groove 12 located outside the inner tank 11. The annular groove 12 has two parallel and spaced-apart straight sections. The housing 1 is provided with an inlet pipe 22 and an outlet pipe communicating with the inner tank 11. The filter structure 2 is installed in the inner tank 11 and has multiple filter sections, capable of filtering impurities in the wastewater. The cleaning component 3 is located above the housing 1 and can clean the filter sections. The linkage adjustment group 4 is located on the housing 1 and is poweredly connected to both the filter structure 2 and the cleaning component 3, enabling the cleaning component 3 to clean each filter section individually while the filter structure 2 is filtering the liquid in the inner tank 11.

[0039] Compared with the prior art, the circulating sewage three-dimensional treatment equipment provided in this embodiment can simultaneously coordinate the filter structure 2 and the cleaning component 3 through the linkage adjustment group of 4 pieces. This ensures that each filter part in the filter structure 2 corresponds to the cleaning component 3 and is cleaned by the cleaning component 3. The cleaning of each filter part can be completed without stopping the machine, which not only improves the filtration effect of the filter structure 2, but also reduces the workload of the staff to a certain extent. It is highly practical.

[0040] In some embodiments, the filter structure 2 described above can be as follows: Figure 2 The structure shown. See also Figure 2The filter structure 2 includes a connecting shaft 23 and filter plates 21. The connecting shaft 23 is rotatably mounted on the housing 1. The connecting shaft 23 is connected to four filter plates 21. Each filter plate 21 is arranged in a ring around the axis of the connecting shaft 23, and each filter plate 21 extends radially along the connecting shaft 23.

[0041] Each filter plate 21 is a filter section.

[0042] The inner groove 11 is a semi-circular groove with a circumferential surface corresponding to the protruding end of each filter plate 21, and the axis of the inner groove 11 is collinear with the axis of the connecting shaft 23.

[0043] The filter plates 21 are provided in four positions, which ensures that two filter plates 21 can be set horizontally each time as the filter plates 21 rotate with the connecting shaft 23, which is convenient for cleaning and can also increase the cleaning area and improve cleaning efficiency.

[0044] In this embodiment, the filter plates 21 can also be set to six, eight, etc.

[0045] It should be noted that the connecting shaft 23 can rotate clockwise. In this case, the water inlet pipe 22 needs to be connected to the end of the filter plate 21 in the inner tank 11 that rotates upwards. See [reference needed]. Figure 2 Preferably, since the included angle between two adjacent filter plates 21 is 90°, the angle between the line connecting the outlet end of the inlet pipe 22 to the connecting shaft 23 and the line connecting the inlet end of the outlet pipe to the connecting shaft 23 should be greater than 90° to prevent the liquid to be filtered from being discharged directly from the outlet pipe.

[0046] In some embodiments, the cleaning component 3 described above may employ, for example... Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The structure shown. See also Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7The cleaning component 3 includes a reciprocating screw 31, mounting blocks 32, mounting parts 39, and a rack 35. The reciprocating screw 31 is rotatably mounted on the top of the housing 1 along a horizontal direction perpendicular to the axis of the connecting shaft 23, and is positioned along the axis of the connecting shaft 23. Both ends of the reciprocating screw 31 are provided with bidirectional threads. Two mounting blocks 32 are provided, located at opposite ends of the housing 1 along the length of the reciprocating screw 31 and slidably connected to the housing 1. Each mounting block 32 is helically connected to both ends of the reciprocating screw 31. Each mounting block 32 is slidably connected to a mounting shaft 33, the axis of which is perpendicular to the axis of the reciprocating screw 31. A sleeve 36 is rotatably fitted onto the mounting shaft 33, and the outer wall of the sleeve 36 is evenly distributed with several brushes 38. One end of the sleeve 36 is provided with an adjusting gear 37. The mounting part 39 is located at the end of the mounting shaft 33 away from the adjusting gear 37. The mounting part 39 is provided with a connecting rod 34, one end of which is slidably engaged with the annular groove 12. The rack 35 is fixedly mounted on the top of the housing 1, and its length direction is set along the length direction of the reciprocating screw 31. The rack 35 can be engaged with the adjusting gear 37 after the mounting shaft 33 drives the sleeve 36 to move.

[0047] This structure ensures that when the reciprocating screw 31 drives the mounting block 32 to move closer to the connecting shaft 23, the adjusting gear 37 disengages from the rack 35. When the mounting block 32 moves away from the connecting shaft 23, the annular groove 12 limits the connecting rod 34, causing the sleeve 36 to move axially, so that the adjusting gear 37 engages with the rack 35, thereby realizing the rotation of the sleeve 36 and ensuring the cleaning effect on the filter section.

[0048] Of course, when there is only one reciprocating screw 31, the threads on the two mounting blocks 32 are set in opposite directions. Alternatively, there can be two reciprocating screws 31, which are coaxially arranged.

[0049] In this embodiment, the mounting block 32 can be slidably connected to the limiting slide rail provided on the top of the housing 1, and the mounting block 32 is provided with a sliding hole for the mounting shaft 33 to be slidably connected.

[0050] In this embodiment, the annular groove 12 can be located between the inner groove 11 and the lead screw. The annular groove 12 can be approximated as a parallelogram trajectory, as shown in [reference needed]. Figure 3 Its annular groove 12 is provided in two parts, corresponding to two sleeves 36 respectively.

[0051] In some embodiments, the above-mentioned four linkage adjustment components can be adopted as follows: Figure 2 The structure shown. See also Figure 2The linkage adjustment group consists of four components: a reversing shaft 41, a second transmission gear 43, a power shaft 46, and a driven grooved wheel 49. The reversing shaft 41 is rotatably mounted on the top of the housing 1 and perpendicular to the reciprocating screw 31. One end of the reversing shaft 41 is fixedly connected to a first transmission wheel 44, and the other end is fixedly connected to a first transmission gear 42. The second transmission gear 43 is fixedly mounted on the reciprocating screw 31 and meshes with the first transmission gear 42. The power shaft 46 is rotatably mounted outside the housing 1. A drive dial 47 and a second transmission wheel 48 are connected to the power shaft 46, and the first transmission wheel 44 and the second transmission wheel 48 are poweredly connected via a transmission component 45. The driven grooved wheel 49 is fixedly mounted on one end of the connecting shaft 23 and has four elongated notches that are sequentially actuated by levers mounted on the drive dial 47.

[0052] In this embodiment, the power shaft 46 can be connected to an external driver. The power shaft 46 drives the active dial 47 and the second transmission wheel 48 to rotate simultaneously. The second transmission wheel 48 can transmit power to the first transmission wheel 44 through the transmission component 45, and then drive the first transmission gear 42 through the reversing shaft 41, which in turn drives the reciprocating screw 31 to rotate. In addition, the active dial 47 can slide into the elongated notch through the lever. When the lever enters the elongated notch, it will drive the driven groove wheel 49 to rotate. Preferably, the driven groove wheel 49 is provided with four elongated notches at an annular interval to correspond to the four filter plates 21. The lever will drive the driven groove wheel 49 to rotate a quarter turn through one of the elongated notches, thereby changing the vertical filter plate 21 to a horizontal position, or the horizontal filter plate 21 to a vertical position. After the lever disengages from the long slot, it will rotate freely three-quarters of a turn and then fit into the next long slot. During this process, the reciprocating screw 31 will drive the two mounting blocks 32 to achieve a reciprocating cycle, that is, move from the outside of the filter plate 21 close to the connecting shaft 23, and then move from the connecting shaft 23 to the outside of the filter plate 21 to clean the impurities on the horizontally set filter plate 21.

[0053] The reciprocating screw 31 needs to have a certain length to ensure that the mounting block 32 can always be on the outside of the inner groove 11 during the process of the lever driving the long notch to travel a quarter circle.

[0054] In some embodiments, the connecting rod 34 may be adopted as follows: Figure 7 The structure shown. See also Figure 7 The end of the connecting rod 34 that extends into the annular groove 12 has a spherical part to ensure that the connecting rod 34 can slide smoothly in the annular groove 12 and has high stability.

[0055] In some embodiments, the adjusting gear 37 and rack 35 described above can be employed as follows: Figure 5 The structure shown. See also Figure 5The teeth of both the adjusting gear 37 and the rack 35 are helical teeth. This structure can ensure the overlap during the meshing process and also facilitate the meshing of the two.

[0056] In some embodiments, the cleaning brush 38 described above can be employed as follows: Figure 7 The structure shown. See also Figure 7 All cleaning brushes 38 are arc-shaped. The arc-shaped cleaning brushes 38 can ensure a counterclockwise rotational fit with the filter plate 21 to improve the cleaning effect.

[0057] The working principle of the circulating wastewater three-dimensional treatment equipment provided in this embodiment is as follows:

[0058] Water to be filtered is injected into the inner tank 11 of the housing 1 through the inlet end of the inlet pipe 22. The filter plates 21 filter impurities from the wastewater, allowing it to enter from the inlet end of the inlet pipe 22 and exit from the outlet end. Simultaneously, as the wastewater is filtered, the power shaft 46 at one end of the housing 1 rotates counterclockwise, driving the active dial 47 to rotate. At this time, the mounting shaft 33 drives the sleeve 36 to be positioned outside the base circle formed by the outer ends of each filter plate 21. Because the active dial 47 is connected to the driven grooved wheel 49, it further drives the connecting shaft 23 to rotate. The connecting shaft 23 then drives the filter plate 21, which is fixedly connected to it, to rotate a quarter turn. At this point, the mounting shaft 33 moves the sleeve 36 to the end of the filter plate 21 closest to the connecting shaft 23. While the drive shaft 46 drives the active dial 47 to rotate, the second transmission wheel 48 also rotates accordingly. Since the second transmission wheel 48 is connected to the first transmission wheel 44 through the transmission component 45, it can further drive the reversing shaft 41 to rotate. The reversing shaft 41 then drives the first transmission gear 42 located at one end inside the housing 1 to rotate. Through the meshing transmission between the first transmission gear 42 and the second transmission gear 43, it can further drive the reciprocating screws 31 at both ends of the reversing shaft 41 to rotate in different directions. Since the mounting block 32 and the reciprocating screw 31 are connected... The threaded engagement allows the reciprocating screw 31 to rotate, driving the mounting shaft 33 in the middle of the mounting block 32 to move axially along the reciprocating screw 31. During the movement of the mounting shaft 33, the connecting rod 34 at one end of the mounting shaft 33 moves along the path of the annular groove 12 until it moves from the outside of the annular groove 12 to the inside of the annular groove 12. (When the mounting shaft 33 moves towards the connecting shaft 23, the adjusting gear 37 and the rack 35 will not mesh, meaning the connecting rod 34 is on the outside of the annular groove 12. When the mounting shaft 33 moves towards the connecting shaft 23...) When the adjusting gear 37 meshes with the rack 35 (i.e., reaches the inner side of the annular groove 12), and the connecting rod 34 reaches the inner side of the annular groove 12, it can drive the mounting shaft 33 to move axially along the reversing shaft 41, ultimately causing the adjusting gear 37 at one end of the sleeve 36 to mesh with the rack 35. At the same time, the mounting block 32 reaches the end of the reciprocating screw 31. Since the adjusting gear 37 and the rack 35 are meshed at this time, the mounting shaft 33 can move outward along the path of the reciprocating screw 31, and the sleeve 36 on the mounting shaft 33 will rotate around the mounting block 31. The shaft 33 rotates axially, and through the rotation of the sleeve 36, the cleaning brush 38 can sweep the top surface of the filter plate 21, and finally clean the impurities on the two horizontally set filter plates 21, so that the impurities are concentrated in the collection groove at the outer end of the housing 1. As the power shaft 46 achieves rotation adjustment within one cycle, the positions of the filter plate 21 that was originally in the vertical position and the filter plate 21 that was in the horizontal position are interchanged. Through the re-transmission and cooperation of the linkage adjustment group 4, the impurities attached to the top surface of the two filter plates 21 in the horizontal position can be cleaned.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
