Description

Technical Field

[0001] The present invention belongs to the field of sewage treatment, and particularly relates to a self-cleaning sewage treatment device based on solid-liquid separation. Background Art

[0002] With the rapid development of the economic society, the total amount of sewage discharge is increasing continuously, and sewage treatment has become increasingly important. As a key sewage treatment technology, solid-liquid separation of sewage can effectively reduce the burden of solid substances in sewage on subsequent treatment equipment, and improve the treatment effect and efficiency.

[0003] At present, there are various types of sewage treatment equipment on the market, but traditional solid-liquid separation devices generally have some problems. For example:

[0004] Traditional filter screen type solid-liquid separation devices are easily blocked by impurities in sewage, resulting in a decrease in filtration efficiency and even inability to work properly. Regular shutdown for manual cleaning is required, which affects the continuity and efficiency of sewage treatment;

[0017] The connection part of the sewage branch pipe and the separation cylinder can be located in the upper left part of the separation cylinder.

[0018] Furthermore, a water storage cylinder and a filter residue cylinder are respectively arranged on the left and right sides at the bottom of the separation cylinder;

[0019] There are water outlet mesh holes corresponding to the water storage cylinder on the circumferential surface of the lower left part of the separation cylinder;

[0020] There is a slag outlet corresponding to the filter residue cylinder on the circumferential surface of the lower right part of the separation cylinder; a support partition net is arranged in the filter residue cylinder, and the support partition net is a filter mesh structure; a spiral feeding blade is rotatably arranged on the support partition net, a servo motor for driving the spiral feeding blade to rotate is installed on the outer wall of the filter residue cylinder, and the other end of the filter residue cylinder is connected with a discharge cylinder, and the discharge cylinder is communicated with the tail end of the support partition net;

[0021] Both the filter residue cylinder and the water storage cylinder are supported and fixedly installed on the bottom box;

[0026] The water inlet end of the water pump is connected to the internal water storage cavity of the bottom box through a first water pipe, and the water outlet end of the water pump is connected to the inner cavity of the water storage cover through a second water pipe. The water storage cover is coaxially and fixedly installed on the outer wall of one end of the separation cylinder. The water inlet nozzles of multiple water pipes are arranged on the outer circumferential surface of the rotating ring seat.

[0027] Furthermore, a fixed ring seat is coaxially and fixedly arranged on the outer wall of the end of the separation cylinder, and a sealed connection is provided between the outer ring of the fixed ring seat and the inner surface of the open mouth of the water storage cover;

[0032] Compared with the prior art, the beneficial effects of the self-cleaning sewage treatment equipment based on solid-liquid separation of the present invention are as follows:

[0033] First, during the rotation of the rotating sleeve relative to the main drainage pipe, when one of the drainage movable openings aligns with the drainage fixed opening, the sewage in the corresponding separation cavity of the current drainage movable opening undergoes solid-liquid separation through the corresponding separation plate group. The separated wastewater enters the main drainage pipe through the drainage movable opening and the drainage fixed opening for discharge, while the filter residue of the sewage remains in the separation cavity;

[0034] Second, when the separation plate group corresponding to the current separation cavity becomes blocked, as sewage continues to be injected into the separation cavity, the sewage in the separation cavity gradually increases. When the separation cavity is filled with sewage, it will cause the rotating sleeve to rotate relative to the main drainage pipe, so that the next separation cavity aligns with the sewage injection position of the sewage branch pipe to utilize the separation plate group of the next separation cavity for solid-liquid separation treatment of sewage, reducing the situation of shutdown for maintenance; and so on in a cycle, continuous solid-liquid separation can be achieved, and the sewage treatment efficiency is high;

[0035] Thirdly, when the blocked separation plate group rotates to the upper right part of the separation cylinder, multiple first nozzles distributed in an array eject water to reversely flush the filter plate. During the flushing, the filter plate will move away from the bottom plate, causing the protective ring to rotate by a certain angle, making the water outlet nozzle of the second nozzle exposed. At this time, the second nozzle can also eject water, which helps the current separation plate group to rotate counterclockwise. The flushed and cleaned separation plate group rotates counterclockwise to below the water injection point of the sewage branch pipe, enabling the sewage-filled separation chamber to smoothly perform a counterclockwise conversion movement within the separation cylinder, realizing the continuity of sewage solid-liquid separation treatment.

[0055] The following describes the specific implementation of the present invention in detail in combination with specific embodiments.

[0056] As Figures 1 - 3 shown, it is a structural schematic diagram of a self-cleaning sewage treatment device based on solid-liquid separation provided by an embodiment of the present invention. The self-cleaning sewage treatment device provided by the embodiment of the present invention includes a separation cylinder 2, the separation cylinder 2 is placed horizontally, and a main drainage pipe 4 is coaxially supported and fixed inside the separation cylinder 2. The main drainage pipe 4 is used to drain the separated wastewater in the separation cylinder 2. The water outlet end of the main drainage pipe 4 can be connected to the water pipe of the wastewater system to drain the wastewater separated from the separation cylinder 2;

[0057] Among them, a drainage fixed through port 41 is opened on the main drainage pipe 4 located inside the separation cylinder 2, and the wastewater in the separation cylinder 2 enters the main drainage pipe 4 through the drainage fixed through port 41 to achieve further drainage;

[0058] In addition, as Figure 2 and Figure 4As shown, in the embodiment of the present invention, a rotating sleeve 5 sleeved on the outer circumference of the drain main pipe 4 is coaxially and rotatably arranged in the separation cylinder 2. Three separation plate groups 6 are arranged on the outer circumference of the rotating sleeve 5. The three separation plate groups 6 divide the inner cavity of the separation cylinder 2 into three separation chambers. And three drainage movable openings 51 are arranged on the rotating sleeve 5 in a circumferential array distribution. The three drainage movable openings 51 respectively correspond to the three separation chambers. During the rotation of the rotating sleeve 5 relative to the drain main pipe 4, when one of the drainage movable openings 51 is aligned with the drainage fixed opening 41, the sewage in the separation chamber corresponding to the current drainage movable opening 51 is subjected to solid-liquid separation through the corresponding separation plate group 6. The separated wastewater enters the drain main pipe 4 through the drainage movable opening 51 and the drainage fixed opening 41 for discharge, while the filter residue of the sewage remains in the separation chamber.

[0059] Preferably, in the embodiment of the present invention, a sewage main pipe 3 is further included. The sewage main pipe 3 is used to send the sewage to be treated into the separation cylinder 2. Among them, the water outlet end of the sewage main pipe 3 is connected with a plurality of sewage branch pipes 31. The plurality of sewage branch pipes 31 are communicated with the upper part of the separation cylinder 2. By arranging the plurality of sewage branch pipes 31, the sewage can be injected into the separation cylinder 2 for the sewage to be treated at multiple points arranged in a straight row, avoiding the situation that when the sewage is injected at a concentrated place, the excessive impact force causes the rotating sleeve 5 to rotate relative to the drain main pipe 4, playing a role in dispersing the impact force of the sewage.

[0060] As Figure 2 shown, the connection part of the sewage branch pipe 31 and the separation cylinder 2 can be located at the upper left part of the separation cylinder 2, so as to align the water injection part of the sewage branch pipe 31 with the corresponding separation chamber.

[0061] When the separation plate group 6 corresponding to the current separation chamber is blocked, as the sewage continues to be injected into the separation chamber, the sewage in the separation chamber gradually increases. When the separation chamber is filled with sewage, it will cause the rotating sleeve 5 to rotate relative to the drain main pipe 4 (as Figure 2 shown, it rotates counterclockwise), so that the next separation chamber is aligned with the sewage injection position of the sewage branch pipe 31, so as to use the separation plate group 6 of the next separation chamber to carry out solid-liquid separation treatment of the sewage;

[0062] In this way, continuous solid-liquid separation can be realized, and the sewage treatment efficiency is high.

[0063] Correspondingly, please continue to refer to Figures 1 - 3 , in the embodiment of the present invention, a water storage cylinder 22 and a filter residue cylinder 21 are respectively arranged on the left and right sides of the bottom of the separation cylinder 2. Among them, the water storage cylinder 22 is used to discharge the sewage in the blocked separation chamber, and the filter residue cylinder 21 is used to collect and discharge the filter residue in the separation chamber;

[0064] Among them, as Figure 7As shown, on the lower left circumferential surface of the separation cylinder 2, there are water outlet mesh holes 25 corresponding to the water storage cylinder 22, so that the sewage in the blocked separation cavity can be discharged into the water storage cylinder 22 through the water outlet mesh holes 25; correspondingly, on the lower right circumferential surface of the separation cylinder 2, there is a slag outlet 26 corresponding to the slag filter cylinder 21, and the slag outlet 26 directly adopts a large through-hole structure, which is convenient for the filter residue to directly fall into the slag filter cylinder 21.

[0065] In one implementation, as Figure 2 , Figure 3 and Figure 6 shown, a support partition net 24 is arranged in the slag filter cylinder 21. The support partition net 24 is a filter net structure, which is used to discharge some residual sewage in the filter residue, while the filter residue remains on the support partition net 24; a spiral feeding blade 2111 is rotatably arranged on the support partition net 24, and a servo motor 211 for driving the spiral feeding blade 2111 to rotate is installed on the outer wall of the slag filter cylinder 21. The other end of the slag filter cylinder 21 is connected with a discharge cylinder 212, and the discharge cylinder 212 communicates with the tail end of the support partition net 24, which is used to push the filter residue to the discharge cylinder 212 through the spiral feeding blade 2111 for discharge. There is a filter residue collection tank 12 below the discharge cylinder 212, and the filter residue collection tank 12 is used to receive the filter residue discharged from the discharge cylinder 212.

[0066] Preferably, please continue to refer to Figure 1 and Figure 2 , the slag filter cylinder 21 and the water storage cylinder 22 are both supported and fixedly installed on the bottom box 1, so that the slag filter cylinder 21 and the water storage cylinder 22 can act as the feet of the separation cylinder 2 to fix the separation cylinder 2; in addition, the bottom of the water storage cylinder 22 and the bottom of the slag filter cylinder 21 are both connected to the water storage cavity inside the bottom box 1 through a surplus water outlet pipe 213, which is used to collect the excess sewage in the water storage cylinder 22 and the slag filter cylinder 21; the filter residue collection tank 12 is installed on the bottom box 1.

[0067] Particularly, as Figure 4 , Figure 5 , Figures 7 - 10 shown, in one implementation of the separation plate group 6 of the present invention, the separation plate group 6 includes a bottom plate 61. One end of the bottom plate 61 is fixedly connected to the outer circumferential surface of the rotating sleeve 5, and the other end of the bottom plate 61 is integrally formed with a tail seat 65, and the outer surface of the tail seat 65 contacts the inner wall surface of the separation cylinder 2;

[0068] Optionally, the outer surface of the tail seat 65 may have a wear-resistant rubber layer, which is used to generate a contact friction force between the outer surface of the tail seat 65 and the inner wall surface of the separation cylinder 2, and play a limiting role in the position of the separation plate group 6 in the separation cylinder 2. When the separation cavity is filled with sewage and the gravity of the sewage is greater than the above contact friction force, the tail seat 65 can slide relative to the inner wall surface of the separation cylinder 2;

[0069] Further, the separation plate group 6 further includes a filter plate 62. One end of the filter plate 62 is rotatably connected to the outer periphery of the rotating sleeve 5 through a hinge shaft. The other end of the filter plate 62 abuts against the receiving grooves 651 inside the tailstock 65. There are multiple receiving grooves 651, and the central axis of the arc surface of the receiving groove 651 is coaxial with the hinge shaft. When the filter plate 62 rotates around its hinge shaft, the other end of the filter plate 62 always contacts the arc surface of the receiving groove 651.

[0070] Further, a plurality of second nozzles 68 are provided at the top of the tailstock 65, and the plurality of second nozzles 68 correspond to the plurality of receiving grooves 651; the plurality of second nozzles 68 are all connected in series on a horizontal water pipe, and a plurality of protective rings 69 are rotatably sleeved on the horizontal water pipe. The plurality of protective rings 69 correspond to the plurality of second nozzles 68 one by one. Each protective ring 69 has a protective opening 691. When the protective ring 69 rotates a certain angle, the protective opening 691 can be aligned with the second nozzle 68. At this time, the second nozzle 68 can eject water, and when the protective opening 691 is not aligned with the second nozzle 68, the protective ring 69 plays a protective role for the second nozzle 68.

[0071] Furthermore, the protective ring 69 and the end of the filter plate 62 are connected through a connecting plate 64. Specifically, the end of the filter plate 62 is hinged to the bottom end of the connecting plate 64, and the top end of the connecting plate 64 is hinged to the protective ring 69; in addition, the filter plate 62 and the bottom plate 61 are supported and connected through a connecting spring 63. When the separation chamber is filled with sewage, the filter holes of the surface filter plate 62 are blocked. At this time, the connecting spring 63 will be compressed to a certain extent. When the end of the filter plate 62 is pressed down, the protective ring 69 is pulled to rotate clockwise by a certain angle through the connecting plate 64. The second nozzle 68 is located inside the protective ring 69, realizing the protective effect on the second nozzle 68; on the contrary, when the filter plate 62 is lifted upward relative to the bottom plate 61, the protective ring 69 can be rotated counterclockwise by a certain angle, and the second nozzle 68 is exposed. At this time, when the second nozzle 68 ejects water, it helps to drive the separation plate group ⑥ to rotate counterclockwise in the separation cylinder 2.

[0072] As a preference, as Figure 4 shown, a plurality of first nozzles 67 are arranged in an array distribution on the surface of the bottom plate 61 facing the filter plate 62. A plurality of water pipes 66 are arranged on the other side of the bottom plate 61. The horizontal water pipe and the first nozzles 67 on the tailstock 65 are respectively connected to the corresponding water pipes 66. The water pipes 66 are used to extract the residual sewage collected in the bottom box 1.

[0073] In the specific implementation of the separation plate group 6 of the embodiment of the present invention, the blocked separation plate group 6 operates to as Figure 2When it is at the upper right part of the separation cylinder 2 shown, at this time, start the lift pump 13 that conveys water into the water delivery pipe 66. When the multiple first nozzles 67 distributed in an array eject water, the filter plate 62 is reversely flushed. During the flushing, the filter plate 62 will move away relative to the bottom plate 61, thereby causing the protective ring 69 to rotate by a certain angle, making the water outlet nozzle of the second nozzle 68 exposed. At this time, the second nozzle 68 can also eject water, which helps the current separation plate group 6 to rotate counterclockwise, and helps the washed and cleaned separation plate group 6 to rotate counterclockwise to below the water injection point of the sewage branch pipe 31 (this process also cooperates with and facilitates the downward reverse rotation action when the previous separation chamber is filled with sewage), so that the separation chamber filled with sewage can smoothly perform a counterclockwise conversion movement in the separation cylinder 2, realizing the continuity of the sewage solid-liquid separation treatment.

[0074] Further, please refer to Figure 2 , in the embodiment of the present invention, a sensor group 7 is arranged on the inner ring inner wall of the separation cylinder 2. The sensor group 7 is used to control the start and stop of the lift pump 13. Among them, the sensor group 7 includes a stop sensor 71 and a start sensor 72. When the outer side of the tail seat 65 of the separation plate group 6 first touches the start sensor 72, the start sensor 72 controls the lift pump 13 to start. When the outer side of the tail seat 65 of the separation plate group 6 touches the stop sensor 71, the stop sensor 71 controls the lift pump 13 to close.

[0075] In an implementation manner of the present invention, both the stop sensor 71 and the start sensor 72 adopt contact pressure switches. When the tail seat 65 abuts against the sensor, a certain extrusion is generated on the sensor, and the sensor obtains a pressure signal therefrom; specifically, during implementation, the stop sensor 71 is only used to send a closing signal to the lift pump 13. When the stop sensor 71 is extruded by the tail seat 65 and in response to the generated pressure signal, the stop sensor 71 will generate a closing signal to close the lift pump 13; on the contrary, the start sensor 72 is only used to send a start signal to the lift pump 13. When the start sensor 72 is extruded by the tail seat 65 to generate a pressure signal, a start signal to open the lift pump 13 is generated, which is used to control the lift pump 13 to open.

[0076] Please continue to refer to Figure 1 and Figure 3 , in the embodiment of the present invention, a lift pump 13 is arranged on the bottom box 1. The lift pump 13 is electrically connected to the start sensor 72 and the stop sensor 71, that is, the start sensor 72 triggers the lift pump 13 to start, and the stop sensor 71 triggers the lift pump 13 to close;

[0077] Correspondingly, the water inlet end of the water pump 13 is connected to the internal water storage cavity of the bottom box 1 through the first water pipe 131, and the water outlet end of the water pump 13 is connected to the inner cavity of the water storage cover 23 through the second water pipe 132. The water storage cover 23 is coaxially and fixedly installed on the outer wall of one end of the separation cylinder 2. By disassembling the water storage cover 23, it is convenient to maintain the rotating ring seat 231 inside the water storage cover 23 and the water inlet nozzle 661 on the water pipe 66.

[0078] Optionally, a water pressure sensor can be provided on the water storage cover 23 to detect the water pressure inside the water storage cover 23 in real time. When the filter plate 62 is flushed during the start of the water pump 13, a warning is issued for insufficient water pressure to give a reminder.

[0079] Specifically, in the embodiment of the present invention, the water storage cover 23 is used for the transit function of injecting flushing water into the water pipe 66. Specifically, the water inlet nozzles 661 of multiple water pipes 66 are arranged on the outer circumferential surface of the rotating ring seat 231. A fixed ring seat 232 is also coaxially and fixedly arranged on the outer wall of the end of the separation cylinder 2. The outer ring of the fixed ring seat 232 is hermetically connected to the inner surface of the open mouth of the water storage cover 23, and the inner ring of the fixed ring seat 232 is coaxially rotatably sleeved on the outer ring of the rotating ring seat 231. When the rotating sleeve 5 rotates relative to the drain main pipe 4, the rotating ring seat 231 is synchronously driven to rotate coaxially inside the fixed ring seat 232.

[0080] Preferably, the fixed ring seat 232 has a notch 233, and the set notch 233 is adapted to the coverage range of the sensor group 7. When the rotating ring seat 231 rotates and drives the water inlet nozzle 661 of a certain water pipe 66 to enter the area of the notch 233, the water in the water storage cover 23 can enter the current water pipe 66 through the water inlet nozzle 661. This water pipe 66 also corresponds to the separation plate group 6 in the area covered by the sensor group 7, and the separation plate group 6 can be flushed and cleaned. Correspondingly, when the separation plate group 6 leaves the coverage area of the sensor group 7, the water inlet nozzle 661 of the current water pipe 66 will also leave the area of the notch 233, and the fixed ring seat 232 closes the water inlet nozzle 661 of the water pipe 66 that leaves the notch 233.

[0081] During implementation, when the separation plate group 6 that needs to be flushed and cleaned rotates counterclockwise in the separation cylinder 2 until it abuts against the start sensor 72, at this time, the water inlet nozzle 661 of the water delivery pipe 66 corresponding to the current separation plate group 6 also enters the area of the notch 233. At this time, the start sensor 72 controls the start of the water extraction pump 13 by generating a start control instruction. The water extraction pump 13 injects water into the water storage cover 23, and the water in the water storage cover 23 is introduced into the corresponding water delivery pipe 66 through the water inlet nozzle 661 in the area of the notch 233 to perform a flushing and cleaning operation on the current separation plate group 6. Correspondingly, as the separation plate group 6 continues to rotate counterclockwise, when the separation plate group 6 abuts against the stop sensor 71, the water extraction pump 13 is controlled to close.

[0082] In the embodiment of the present invention, the inner ring of the rotating ring seat 231 is coaxially and fixedly sleeved on the outer ring of the end of the rotating sleeve 5;

[0083] The end of the drain main pipe 4 is coaxially and fixedly connected to the inner wall of the water storage cover 23;

[0084] During specific implementation, by cooperating with the stop sensor 71 and the start sensor 72, the flushing and cleaning work of the separation plate group 6 passing through the area where the sensor group 7 is located can be started to clean the current separation plate group 6; and the filtering surface of the separation plate group 6 in the current state faces downward, ensuring the cleaning effect of flushing the filtering surface.

[0085] Please continue to refer to Figure 1 , a control panel 11 is also provided on the front side of the bottom box 1. The control panel 11 has a controller and control buttons, etc. The control buttons are used to manually control the opening or closing of driving parts such as the servo motor 211; the controller can receive the pressure signals of the sensor group 7 and generate corresponding control instructions for controlling the start or stop of the lifting pump 13.

[0086] The above solutions are only illustrations of a preferred example, but are not limited thereto. When implementing the present invention, appropriate substitutions and / or modifications can be made according to the needs of users.
