Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device based on environmental protection. Background Technology

[0002] In order to protect the natural environment, it is often necessary to effectively remove pollutants (such as organic matter, nitrogen and phosphorus, heavy metals, pathogens, etc.) through multi-stage treatment to prevent eutrophication of water bodies, ecological damage and health risks.

[0003] Patent CN206927727U discloses a wastewater treatment device, including a primary sedimentation tank, an aeration tank, a sedimentation tank, and a disinfection tank. The primary sedimentation tank has an inlet pipe on one side and an aeration tank on the other. A sludge pump is installed at the bottom of the primary sedimentation tank, with one end connected to a sludge discharge pipe leading to the outside of the primary sedimentation tank. A scraper is installed at the top of the aeration tank, and an aerator is installed on one side of the aeration tank, connected to the interior of the aeration tank via an air supply pipe. The sedimentation tank is located to one side of the aeration tank, with a flocculant storage tank installed at the top and a sludge pump installed at the bottom. The flocculant storage tank is connected to the sedimentation tank via a conduit. One end of the disinfection tank is connected to the sedimentation tank, and the other end has an outlet pipe. A disinfectant storage tank is installed at the top of the disinfection tank, connected to the disinfection tank via a conduit. This device performs multi-stage purification of wastewater, resulting in more thorough wastewater treatment, making it safe to use. It also features a high degree of automation, reducing labor costs.

[0004] However, the above-mentioned multi-stage wastewater treatment devices still have the following problems in actual use:

[0005] Wastewater treatment typically includes three main stages: primary treatment, secondary treatment, and tertiary treatment. Primary treatment mainly removes suspended solids and sand particles from wastewater through physical methods (such as screens, grit chambers, and primary sedimentation tanks). Secondary treatment utilizes biodegradation processes to effectively remove organic matter and nutrients such as nitrogen and phosphorus. Tertiary treatment is a deep purification stage, aiming to further remove trace pollutants so that the effluent meets reuse standards or strict discharge requirements.

[0006] During the primary and secondary treatment processes, some suspended solids in the wastewater will gradually settle to the bottom of the treatment tank due to gravity, forming sludge. To prevent excessive sludge accumulation and facilitate centralized collection and subsequent disposal, wastewater treatment tanks are usually equipped with sludge scraping devices to periodically scrape the sludge from the bottom of the tank to the sludge discharge port.

[0007] However, existing sludge scraping equipment typically operates in the following mode: first, it moves along the bottom of the tank from one end to the other, pushing the sludge deposited at the bottom of the tank to the sludge discharge port; after scraping the sludge, the equipment is raised to the water surface and then returns to the other end of the tank along the water surface to push floating debris (such as oil film, foam or light garbage) to the outlet baffle or the water collection hopper. Since sewage treatment tanks are usually quite long, this reciprocating stroke is relatively long.

[0008] Furthermore, in cold regions such as northern my country, the low temperatures during winter, especially in slow-flowing secondary biological treatment tanks, easily lead to the formation of a thin layer of floating ice or fine ice fragments on the water surface. When the sludge scraper operates on the return journey, floating ice easily accumulates in front of it. As the scraper moves forward, the ice continues to pile up, increasing the operating resistance of the equipment and, in severe cases, causing the scraping mechanism to jam or even stop. Currently, sludge scraping devices on the market have relatively limited functions, mainly focusing on sludge scraping and surface scum removal. They generally lack the ability to effectively break up or guide floating ice, making it difficult to meet the actual needs of long-term, stable, and reliable operation under low-temperature conditions. Summary of the Invention

[0009] In view of the shortcomings of the prior art, the present invention provides an environmentally friendly sewage treatment device that can not only remove sludge from the bottom of the pool by the sludge scraping mechanism, but also break up the floating ice formed on the surface of the sewage.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a wastewater treatment device based on environmental protection, comprising:

[0011] The pool body has an internal cavity, one end of which extends to the surface of the pool body to form the first opening;

[0012] Several sludge scraping mechanisms are provided, which can scrape the sludge at the bottom of the cavity to the sludge discharge port, and the sludge scraping mechanisms can also push the debris floating on the surface of the sewage in the cavity to the water collection hopper.

[0013] The power mechanism drives the sludge scraping mechanism to circulate within the cavity.

[0014] At least one ice-breaking mechanism is provided, which can break up floating ice on the surface of sewage when the sludge scraping mechanism is driven by the power mechanism to circulate within the cavity. The sludge scraping mechanism can also prevent the broken floating ice from clogging the ice-breaking mechanism.

[0015] Furthermore, it also includes a rotating mechanism that drives the ice-breaking mechanism to rotate on the sewage surface about a first axis as the sludge scraping mechanism moves in a cycle. The first axis is parallel to the sewage surface.

[0016] Furthermore, it also includes a reversing mechanism, which can rotate the rotating mechanism from one side of the ice-breaking mechanism to the other side of the ice-breaking mechanism with the ice-breaking mechanism as the axis when the rotating mechanism moves to both ends of the cavity. The reversing mechanism can fix the position of the rotating mechanism after changing its position on both sides of the ice-breaking mechanism.

[0017] Furthermore, it also includes a straightening mechanism that can limit the angle of the sludge scraping mechanism at the bottom of the cavity and on the surface of the sewage.

[0018] Furthermore, the power mechanism includes a motor, a first rod, two chains, six second rods, and eight sprockets. The outer wall of the motor is fixedly connected to the outer wall of the pool. The output shaft of the motor is fixedly connected to one end of the first rod. The other end of the first rod extends into the interior of the pool and is fixedly connected to two of the sprockets. The outer wall of the first rod is rotatably connected to the inner wall of the pool through a first bearing. A seal is provided at the penetration point between the first rod and the pool. One end of each of the six second rods is rotatably connected to the inner wall of the pool through a second bearing. The other ends of the six second rods are fixedly connected to the remaining six sprockets. The eight sprockets are divided into two groups. The two chains mesh with the two groups of sprockets respectively. Several sludge scraping mechanisms are connected to the two chains.

[0019] Furthermore, the sludge scraping mechanism includes a first plate, a fourth plate, and several first magnets. The several first magnets are divided into two groups, and the two groups of first magnets are fixedly connected to the upper and lower sides of the first plate, respectively. The two groups of first magnets are also connected to the straightening mechanism. The two ends of the first plate are fixedly connected to two chains, respectively. One side of the fourth plate is fixedly connected to one side of the first plate.

[0020] Furthermore, the straightening mechanism includes at least two first magnetic plates, at least two second magnetic plates, and several first blocks. The several first blocks are divided into two groups. The ends of the two groups of first blocks that are far apart from each other are fixedly connected to the two sides of the cavity near the first opening. The ends of the two groups of first blocks that are adjacent to each other are fixedly connected to the two sides of the two second magnetic plates that are far apart from each other. The bottom surfaces of the two first magnetic plates are fixedly connected to the two sides of the bottom surface of the cavity. The two groups of first magnets are aligned with the two first magnetic plates and the two second magnetic plates, respectively, and the first magnets attract the first magnetic plates and the second magnetic plates.

[0021] Furthermore, the ice-breaking mechanism includes a third plate, a third rod, a fifth plate, two second blocks, at least two second magnets, at least one third magnet, and several L-shaped rods. The two ends of the third rod are rotatably connected to the same end of the third plate and the fifth plate respectively via two third bearings. The other ends of the third plate and the fifth plate are respectively connected to the two ends of the first plate. The surface of the third rod is fixedly connected to one end of several L-shaped rods. One end of the third rod is connected to a rotating mechanism. The two second blocks are fixedly connected to the two ends of the first plate respectively. The surfaces of the third plate and the fifth plate abut against the surfaces of the two second blocks respectively. The third magnet is fixedly connected to the inner wall of the fifth plate. The two second magnets are both fixedly connected to the same end of the first plate. The third magnet cooperates with the two second magnets to attract each other.

[0022] Both ends of the first plate are provided with L-shaped openings. The third plate and the fifth plate are rotatably connected to the first plate via the fourth bearing. The two L-shaped blocks are located in the two L-shaped openings respectively, and the L-shaped blocks are fastened to the L-shaped openings by bolts.

[0023] The fourth plate has several second openings on the side away from the first plate, and these second openings are respectively misaligned with several L-shaped rods.

[0024] Furthermore, the reversing mechanism includes a second plate, a fourth rod, a second gear, two second rack plates, and two third blocks. One side of the second plate is fixedly connected to the upper end of the cavity. One end of the fourth rod is fixedly connected to the side of the third plate away from the L-shaped block. The other end of the fourth rod is fixedly connected to the inner wall of the second gear. The end of the fourth rod that passes through the second gear also abuts against the side of the second plate away from the cavity wall. One side of each of the two third blocks is fixedly connected to both ends of the cavity. The other side of each of the two third blocks is fixedly connected to one side of each of the two second rack plates. The second gear meshes with both second rack plates.

[0025] Furthermore, the rotating mechanism includes a first rack plate and a first gear. The bottom surface of the first rack plate is fixedly connected to the upper surface of several first blocks, and the first gear is fixedly connected to one end of the third rod. The first gear meshes with the first rack plate.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] This environmentally friendly wastewater treatment device, through the linkage design of the ice-breaking mechanism and the sludge scraping mechanism, simultaneously breaks up floating ice during the sludge scraping cycle operation, completely solving the problem of equipment jamming and shutdown caused by floating ice accumulation in wastewater treatment ponds in northern winters. Moreover, it does not require additional independent ice-breaking equipment, significantly reducing the operation and maintenance costs and equipment investment of wastewater treatment in low-temperature areas, and ensuring the stable operation of the wastewater treatment system in winter.

[0028] This environmentally friendly wastewater treatment device uses a power mechanism to drive a sludge scraping mechanism to achieve continuous cyclical movement, simultaneously completing three core tasks: sludge scraping from the bottom of the pool, pushing debris from the water surface, and breaking and collecting floating ice. This improves the efficiency of the primary treatment stage of wastewater treatment, shortens the wastewater retention cycle, and increases the overall treatment throughput.

[0029] This environmentally friendly wastewater treatment device features an L-shaped rod in the ice-breaking mechanism that is misaligned with the fourth plate. During the ice-breaking process, it automatically cleans up the adhering ice fragments and debris, thus eliminating the risk of blockage at the source and increasing the equipment's trouble-free operating time.

[0030] This environmentally friendly wastewater treatment device features a reversing mechanism that automatically completes a 180° turn of the ice-breaking mechanism via a rack and pinion meshing structure, eliminating the need for an additional power source. During the sludge scraping stage, the ice-breaking mechanism is rotated to a non-interfering position to avoid increased sludge scraping resistance. When traveling on the water surface, it automatically resets to the ice-breaking mode, enabling a single power system to drive multi-functional collaborative operation and reducing equipment energy consumption.

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0050] Please see Figures 1-10 An environmentally friendly wastewater treatment device includes:

[0051] The pool body 1 has a cavity 101 inside, and one end of the cavity 101 extends to the surface of the pool body 1 to form a first opening;

[0052] Several sludge scraping mechanisms 3 are provided, which can scrape the sludge at the bottom of the cavity 101 to the sludge discharge port, and the sludge scraping mechanisms 3 can also push the debris floating on the surface of the sewage in the cavity 101 to the water collection hopper.

[0053] The power mechanism 2 is capable of driving the sludge scraping mechanism 3 to circulate within the cavity 101;

[0054] At least one ice-breaking mechanism 6 is capable of breaking floating ice on the surface of sewage when the power mechanism 2 drives the sludge scraping mechanism 3 to circulate within the cavity 101. The sludge scraping mechanism 3 is also capable of preventing the broken floating ice from clogging the ice-breaking mechanism 6.

[0055] Specifically, by setting a sludge scraping mechanism 3 inside the cavity 101 of the pool body 1, and driving the sludge scraping mechanism 3 to circulate inside the cavity 101 through the power mechanism 2, and then installing an ice-breaking mechanism 6 on one of the sludge scraping mechanisms 3 (if there are multiple ice-breaking mechanisms 6, they can be installed on multiple sludge scraping mechanisms 3 respectively), the sludge scraping mechanism 3 can scrape off the sludge at the bottom of the pool, and at the same time, the ice-breaking mechanism 6 can break up the floating ice formed on the surface of the sewage. The broken floating ice is then pushed into the water collection hopper by the sludge scraping mechanism 3 for collection, thereby avoiding the floating ice from affecting the normal operation of the sludge scraping mechanism 3.

[0056] Furthermore, in order to enable the power mechanism 2 to drive the scraping mechanism 3 to circulate within the cavity 101, as a preferred embodiment of the present invention, please refer to [reference needed]. Figure 1 , Figure 2 , Figure 5 and Figure 6 The power mechanism 2 includes a motor 21, a first rod 23, two chains 22, six second rods 25, and eight sprockets 24. The outer wall of the motor 21 is fixedly connected to the outer wall of the pool 1. The output shaft of the motor 21 is fixedly connected to one end of the first rod 23. The other end of the first rod 23 passes through the interior of the pool 1 and is fixedly connected to two of the sprockets 24. The outer wall of the first rod 23 is rotatably connected to the inner wall of the pool 1 through a first bearing. A seal is provided at the penetration point between the first rod 23 and the pool 1. One end of each of the six second rods 25 is rotatably connected to the inner wall of the pool 1 through a second bearing. The other ends of the six second rods 25 are fixedly connected to the remaining six sprockets 24. The eight sprockets 24 are divided into two groups. The two chains 22 mesh with the two groups of sprockets 24 respectively. Several sludge scraping mechanisms 3 are connected to the two chains 22.

[0057] Specifically, when the scraping mechanism 3 needs to be driven to run, the motor 21 is turned on. The output shaft of the motor 21 drives the first rod 23 to rotate. Then the first rod 23 drives the two sprockets 24 connected to it to rotate. The rotation of the sprockets 24 can drive the other sprockets 24 to rotate through the two chains 22, thereby moving the scraping mechanism 3 connected to the surface of the two chains 22 within the cavity 101.

[0058] It should be noted that the connection between the first rod 23 and the pool body 1 is provided with a sealing element, which can be a sealing bearing, a sealing ring, or a sealing packing, etc. Alternatively, the output shaft of the motor 21 can be connected to the first rod 23 via a synchronous pulley and synchronous belt to drive the first rod 23 to rotate. Any of these options are acceptable and are not limited in any particular case.

[0059] Furthermore, in order for the sludge scraping mechanism 3 to scrape the sludge at the bottom of the cavity 101 to the sludge discharge port, and for the sludge scraping mechanism 3 to push the debris floating on the surface of the sewage in the cavity 101 to the water collection hopper, as a preferred embodiment of the present invention, please refer to [reference needed]. Figure 1 , Figure 2 , Figures 7-9 The sludge scraping mechanism 3 includes a first plate 31, a fourth plate 33, and a plurality of first magnets 32. The plurality of first magnets 32 are divided into two groups. The two groups of first magnets 32 are fixedly connected to the upper and lower sides of the first plate 31 respectively. The two groups of first magnets 32 are also connected to the straightening mechanism 7. The two ends of the first plate 31 are fixedly connected to two chains 22 respectively. One side of the fourth plate 33 is fixedly connected to one side of the first plate 31.

[0060] Specifically, when the motor 21 starts, the chain 22 moves within the cavity 101, so as to... Figure 2 Taking the perspective of the motor 21 as an example, the output shaft of the motor 21 rotates clockwise, causing the chain 22 to rotate clockwise. Then the first plate 31 connected to the chain 22 rotates clockwise, which can push the sludge accumulated at the bottom of the cavity 101 of the pool body 1 to the sludge discharge port at the left end of the pool body 1. Then, it is discharged from the sludge discharge port in the conventional way, which will not be explained in detail here.

[0061] Because the bottom and upper sidewalls of the cavity 101 are equipped with uprighting mechanisms 7, the first plate 31 can be kept vertical when it moves to the bottom and to the surface of sewage. This allows for better force distribution and higher pushing efficiency when pushing sludge or floating objects (such as floating ice).

[0062] Furthermore, in order to ensure that the first plate 31 remains vertical when it moves to the bottom and to the sewage surface, this environmentally friendly sewage treatment device also includes a straightening mechanism 7, which can limit the angle of the sludge scraping mechanism 3 at the bottom of the cavity 101 and the sewage surface.

[0063] To achieve the effect of the aforementioned straightening mechanism 7, as a preferred embodiment of the present invention, please refer to... Figure 3 and Figure 4 The straightening mechanism 7 includes at least two first magnetic plates 71, at least two second magnetic plates 72, and a plurality of first blocks 73. The plurality of first blocks 73 are divided into two groups. The ends of the two groups of first blocks 73 that are far apart from each other are fixedly connected to the two sides of the cavity 101 near the first opening. The ends of the two groups of first blocks 73 that are adjacent to each other are fixedly connected to the two sides of the two second magnetic plates 72 that are far apart from each other. The bottom surfaces of the two first magnetic plates 71 are fixedly connected to the two sides of the bottom surface of the cavity 101. The two groups of first magnets 32 are aligned with the two first magnetic plates 71 and the two second magnetic plates 72 respectively, and the first magnets 32 attract the first magnetic plates 71 and the second magnetic plates 72.

[0064] First, it should be noted that the "magnetism" in the first magnetic plate 71 and the second magnetic plate 72 refers to the metallic material that can be attracted by a magnet, such as martensitic and ferritic stainless steel, which can be attracted by a magnet and has a certain degree of corrosion resistance due to the presence of alloying elements such as chromium, and can be soaked in water.

[0065] Specifically, since the first magnetic plate 71 and the second magnetic plate 72 are installed at the bottom and top of the cavity 101, when the first plate 31 moves to the bottom and to the sewage surface, the two sets of first magnets 32 on the first plate 31 are aligned with the first magnetic plate 71 and the second magnetic plate 72, so that the first plate 31 can be forcibly attracted to the upright position to ensure the effectiveness of pushing sludge and floating ice.

[0066] Furthermore, in order to enable the ice-breaking mechanism 6 to break up the floating ice on the surface of the sewage when the power mechanism 2 drives the sludge scraping mechanism 3 to circulate within the cavity 101, the sludge scraping mechanism 3 can also prevent the broken floating ice from clogging the ice-breaking mechanism 6. As a preferred embodiment of the present invention, please refer to [reference needed]. Figure 5 , Figures 7-10 The ice-breaking mechanism 6 includes a third plate 61, a third rod 62, a fifth plate 63, two second blocks 66, at least two second magnets 65, at least one third magnet 67, and several L-shaped rods 64. The two ends of the third rod 62 are rotatably connected to the same end of the third plate 61 and the fifth plate 63 respectively through two third bearings. The other ends of the third plate 61 and the fifth plate 63 are respectively connected to the two ends of the first plate 31. The surface of the third rod 62 is fixedly connected to one end of several L-shaped rods 64. One end of the third rod 62 is connected to the rotating mechanism 4. The two second blocks 66 are fixedly connected to the two ends of the first plate 31 respectively. The surfaces of the third plate 61 and the fifth plate 63 abut against the surfaces of the two second blocks 66 respectively. The third magnet 67 is fixedly connected to the inner wall of the fifth plate 63. The two second magnets 65 are both fixedly connected to the same end of the first plate 31. The third magnet 67 cooperates with the two second magnets 65 to attract each other.

[0067] More specifically, both ends of the first plate 31 are provided with L-shaped openings 311, and the ends of the third plate 61 and the fifth plate 63 near the first plate 31 are rotatably connected to L-shaped blocks 611 through a fourth bearing. The two L-shaped blocks 611 are respectively located in the two L-shaped openings 311, and the L-shaped blocks 611 are fastened to the L-shaped openings 311 by bolts.

[0068] More specifically, the fourth plate 33 has a plurality of second openings 331 on the side away from the first plate 31, and the plurality of second openings 331 are respectively misaligned with a plurality of L-shaped rods 64;

[0069] Specifically, during installation (since floating ice only forms during cold seasons, there is no need to install the ice-breaking mechanism 6 in hot weather such as summer; in this case, a rubber plug with the same shape as the L-shaped opening 311 can be used to block the L-shaped opening 311 to prevent impurities in the sewage from clogging the L-shaped opening 311 or the threaded hole of the L-shaped opening 311): First, align the L-shaped block 611 with the L-shaped opening 311 and tighten it with bolts to fix the third plate 61 and the fifth plate 63 to the first plate 31, so that the entire ice-breaking mechanism 6 can follow the first plate 31 and move cyclically within the cavity 101;

[0070] During ice breaking: Because the third plate 61 and the fifth plate 63 are connected by a third rod 62 with several L-shaped rods 64 on its surface, and because the third rod 62 is connected to the rotating mechanism 4, the rotating mechanism 4 can keep the third rod 62 rotating on the surface of the sewage, thereby knocking and breaking the floating ice by the several L-shaped rods 64.

[0071] In addition, after the ice floes break, some ice floes and other scum may stick to the surface of several L-shaped rods 64. At this time, the ice floes and other scum sticking to the surface of the L-shaped rods 64 can be scraped off by several second openings 331 on the fourth plate 33, so as to avoid affecting the subsequent ice breaking effect.

[0072] Furthermore, this wastewater treatment device based on environmental protection also includes a rotating mechanism 4, which can drive the ice-breaking mechanism 6 to rotate on the wastewater surface about a first axis when the sludge scraping mechanism 3 moves in a cycle. The first axis is parallel to the wastewater surface.

[0073] To achieve the effect of the aforementioned rotating mechanism 4, as a preferred embodiment of the present invention, please refer to [link / reference needed]. Figures 1-5 , Figure 7 , Figure 8 and Figure 10 The rotating mechanism 4 includes a first rack plate 41 and a first gear 42. The bottom surface of the first rack plate 41 is fixedly connected to the upper surface of a plurality of first blocks 73. The first gear 42 is fixedly connected to one end of the third rod 62. The first gear 42 meshes with the first rack plate 41.

[0074] Specifically, when the first plate 31 moves in a circular motion to the surface of the sewage within the cavity 101, the first gear 42 rotates together with the first plate 31 to the top of the cavity 101. Then, the first gear 42 continues to move and meshes with the first rack plate 41, thereby causing the first gear 42 to rotate together with the third rod 62. This allows several L-shaped rods 64 located on the surface of the third rod 62 to rotate together, so that the L-shaped rods 64 can break the floating ice when they rotate.

[0075] Furthermore, this wastewater treatment device based on environmental protection also includes a reversing mechanism 5. When the rotating mechanism 4 moves to both ends of the cavity 101, the reversing mechanism 5 can rotate the rotating mechanism 4 from one side of the ice-breaking mechanism 6 to the other side of the ice-breaking mechanism 6 with the ice-breaking mechanism 6 as the axis. Moreover, the reversing mechanism 5 can fix the position of the rotating mechanism 4 after changing the position of the rotating mechanism 4 on both sides of the ice-breaking mechanism 6.

[0076] To achieve the effects of the aforementioned reversing mechanism 5, as a preferred embodiment of the present invention, please refer to... Figures 1-4 , Figure 7 , Figure 8 and Figure 10 The reversing mechanism 5 includes a second plate 51, a fourth rod 54, a second gear 55, two second rack plates 52, and two third blocks 53. One side of the second plate 51 is fixedly connected to the upper end of the cavity 101. One end of the fourth rod 54 is fixedly connected to the side of the third plate 61 away from the L-shaped block 611. The other end of the fourth rod 54 is fixedly connected to the inner wall of the second gear 55. The end of the fourth rod 54 that passes through the second gear 55 also abuts against the side of the second plate 51 away from the wall of the cavity 101. One side of each of the two third blocks 53 is fixedly connected to both ends of the cavity 101. The other side of each of the two third blocks 53 is fixedly connected to one side of each of the two second rack plates 52. The second gear 55 meshes with both second rack plates 52.

[0077] Specifically, when it is necessary to break up floating ice, the ice-breaking mechanism 6 needs to be located on the right side of the first plate 31 (within the range of...). Figure 1 and Figure 2 (From the perspective of...) However, because the first plate 31 rotates continuously, when the first plate 31 with the ice-breaking mechanism 6 installed rotates to the bottom of the cavity 101, the ice-breaking mechanism 6 will be located on the left side of the first plate 31. The first plate 31 moves to the left to push the sludge into the sludge discharge port. In order to avoid the ice-breaking mechanism 6 affecting the cleaning of the first plate 31:

[0078] When the ice-breaking mechanism 6 breaks the ice, such as Figures 7-10 As shown, at this time, the third magnet 67 is attracted to the second magnet 65 at the lower right corner of the first plate 31, and the fourth rod 54 is in close contact with the surface of the second plate 51, which restricts the rotation of the ice-breaking mechanism 6, so that the ice-breaking mechanism 6 can only be located on the right side of the first plate 31.

[0079] When the fourth rod 54 moves to the right end of the second plate 51, the fourth rod 54 separates from the second plate 51. Therefore, the ice-breaking mechanism 6 and the first plate 31 are only kept from rotating by the attraction of the third magnet 67 and the second magnet 65. Then the first plate 31 continues to move to the right. Subsequently, the second gear 55 meshes with the second rack plate 52 located on the right side of the cavity 101, so that the second gear 55 can rotate, thereby rotating the second gear 55 by 180°, so that the ice-breaking mechanism 6, which was originally located on the right side of the first plate 31, is moved to the left side of the first plate 31.

[0080] Afterwards, when the first plate 31 continues to move to the bottom of the cavity 101, the ice-breaking mechanism 6 will be located on the right side again due to the reversal of the chain 22. Therefore, it will not affect the cleaning of the sludge at the bottom of the cavity 101 by the first plate 31. Then, when the first plate 31 continues to move to the left end of the cavity 101 with the chain 22, the first plate 31 rises, and the second gear 55 meshes with the second rack plate 52 located on the left side of the cavity 101. This will once again rotate the ice-breaking mechanism 6 from below the first plate 31 to above the first plate 31. Subsequently, when the chain 22 moves to the sewage surface, the ice-breaking mechanism 6 will be located on the right side of the first plate 31 again, thus breaking the ice.

[0081] Although embodiments of the 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 invention, the scope of which is defined by the appended technical solutions and their equivalents.
