Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment equipment, in particular to sewage treatment equipment for an automobile parts processing workshop. Background Art

[0002] During the manufacturing of automotive parts and accessories, processes such as metal cutting, surface treatment, and parts cleaning generate large amounts of industrial wastewater. This wastewater contains harmful substances such as oil pollutants, metal debris, cutting fluid residue, and surface treatment chemicals. If discharged without effective treatment, it will cause serious environmental pollution. Therefore, proper treatment of wastewater from automotive parts processing workshops is particularly important and urgent. Currently, wastewater treatment equipment is widely used in automotive parts processing workshops. Its main function is to remove pollutants from wastewater through physical and chemical methods to achieve water purification and meet discharge standards. The generation of scum is a common and significant issue in the wastewater treatment process. Scum mainly consists of oil, suspended impurities, and flocs formed by some reactions that rise from the wastewater. If this scum is not removed from the water surface in a timely and effective manner, it will not only affect the normal operation of the wastewater treatment equipment and reduce treatment efficiency, but may also cause the scum to re-integrate into the water, affecting the quality of the treated water.

[0003] Sewage treatment equipment in the prior art, such as a scraper device for a sewage treatment flotation machine disclosed in a Chinese patent document with authorization publication number CN114229942B, realizes the synchronous movement of a scraper plate and a mud scraper plate, is easy to operate, and has low cost. The bracket is located outside the shell, and the bracket causes less disturbance to the bubble layer. Sewage is discharged only when the scraper plate moves toward the first end, reducing the impact of incoming water on the scum layer. The water outlet speed of the water distribution pipe is adjusted to be close to the moving speed of the scraper plate, realizing static water inlet and reducing the disturbance of incoming water to the sewage.

[0004] However, in the process of treating sewage, the scraping equipment for the above-mentioned sewage treatment flotation machine in the prior art usually contains a certain amount of oil, because the sewage generated during the manufacturing process of automobile parts and accessories usually contains a certain amount of oil. The oil will float to the water surface in the sewage and be scraped into the slag collecting tank together with the slag when the scraper blade moves. The floating oil and slag cannot be discharged separately. The floating oil and slag need to be separated by additional separation equipment and a certain treatment time to recycle the floating oil and recycle the slag, and the slag needs to be specially harmlessly treated. This increases the cost of sewage treatment, reduces the efficiency of sewage treatment, and affects the production progress of automobile parts processing. Summary of the Invention

[0005] The present invention provides a sewage treatment device for automobile parts processing workshops, aiming to solve the problem in the related art that floating oil and floating scum need to be separated again after being mixed and scraped out by the scraping equipment of the sewage treatment flotation machine, thereby increasing the sewage treatment cost.

[0006] To solve the above-mentioned problem, the present invention provides a wastewater treatment device for an automobile parts processing workshop, which adopts the following technical solution: a wastewater treatment device for an automobile parts processing workshop, comprising a treatment tank, a slag shifting assembly that moves from left to right to shift slag, and a slag discharge chute located at the right end of the treatment tank; the slag shifting assembly comprises a fixed plate, a slag shifting plate hinged to the fixed plate, and a first elastic member connecting the fixed plate and the slag shifting plate, the first elastic member being used to drive the slag shifting plate to a vertical position;

[0007] The slag discharge trough has a separation chamber and a slag storage chamber distributed in sequence on the left and right. A separation module is provided in the separation chamber. The separation module includes a top plate and an oil collecting tank located below the top plate. The upper surface of the top plate forms a bearing surface for bearing floating oil and floating slag. The bearing surface is provided with a filter hole connected to the oil collecting tank. The filter hole allows floating oil to pass through while blocking floating slag.

[0008] The slag shifting assembly has a slag shifting stroke and an extrusion stroke in sequence when moving from left to right; when the slag shifting assembly is in the slag shifting stroke, the slag shifting assembly pushes the slag and floating oil to the right, the slag shifting plate is in a vertical state, and the bottom of the slag shifting plate is located below the bearing surface; when the slag shifting assembly is in the extrusion stroke, the slag shifting plate pushes the slag and floating oil onto the bearing surface, the slag shifting plate is pushed by the top plate and swings to the left, and the first elastic member drives the slag shifting plate to squeeze the slag and floating oil downward.

[0009] Beneficial effect: When the slag prying assembly moves to the right, it can push the slag and oil mixture to the right and push the slag and oil mixture onto the bearing surface of the top plate. When the slag prying plate is in a vertical position, the bottom of the slag prying plate is located below the bearing surface. While pushing the slag and oil mixture onto the bearing surface, the slag prying plate itself is pushed to the left by the top plate in the opposite direction. The slag prying plate overcomes the force of the first elastic member and swings to the left, and the slag and oil mixture is pressed under the slag prying plate. The first elastic member always applies a downward and rightward elastic force to the slag prying plate. The slag prying plate and the top plate can squeeze the slag and oil mixture. The oil flows into the oil collecting tank through the filter holes. The slag is further pushed to the right by the slag prying plate and falls into the slag storage chamber. The sewage treatment equipment for automobile parts processing workshops of the present invention can remove slag from the surface of the treatment tank and separate slag and oil. It does not need to be scraped out and then separated separately using separation equipment, which reduces costs.

[0010] As a further improvement, the slag removing plate is an arc-shaped plate, and the slag removing assembly further includes a pressure plate and a second elastic member connecting the pressure plate and the fixed plate; when the slag removing assembly moves from left to right, the arc-shaped plate is arranged to protrude to the left, the pressure plate is located on the left side of the fixed plate, and the second elastic member applies an upward elastic force to the pressure plate, the top surface of the pressure plate is located above the top surface of the fixed plate, and the right side of the top of the pressure plate has a first arc angle;

[0011] A push plate is fixed on the inner wall of the treatment tank, and the push plate is located above the filter hole. The left side of the bottom of the push plate has a second arc angle. When the slag removing assembly is in the extrusion stroke, the push plate presses down the pressure plate through the first arc angle and the second arc angle. After the pressure plate moves downward, it pushes the slag removing plate that swings to the left to squeeze the slag.

[0012] When the slag plate swings to the left and gradually changes to a horizontal state, the slag plate can be pressed by the push plate and the pressure plate, thereby increasing the extrusion force between the slag plate and the top plate and improving the separation effect of slag and floating oil.

[0013] As a further improvement, the separation module is slidably assembled in the separation chamber along the up-down direction, and a third elastic member is provided in the separation chamber to push the separation module upward;

[0014] The left side of the top plate is provided with an inclined surface, which extends downward from the top and is arranged tilted to the left; when the scraper assembly moves to the right, it is used to push the inclined surface and drive the separation module to move downward.

[0015] The separation module can float up and down. The first elastic member applies a downward force to the slag stripper plate, and the third elastic member applies an upward force to the top plate. When the two are combined, the extrusion force is greater and the separation effect is better.

[0016] As a further improvement, the separation module further includes a bottom plate, the third elastic member is connected to the bottom plate, the oil collecting tank is slidably assembled on the bottom plate along the left and right directions by a slider, and the oil collecting tank has a backwash chamber and an oil collecting chamber from left to right in sequence;

[0017] A connecting rod is also provided in the separation chamber, one end of which is hinged in the separation chamber through a hinge shaft extending forward and backward, and the other end passes through the bottom plate and is hinged to the bottom of the oil collecting tank. When the separation module moves downward, the connecting rod drives the oil collecting tank to move to the left, so that the oil collecting chamber and the filter hole are directly opposite each other; when the separation module moves upward, the connecting rod drives the oil collecting tank to move to the right, so that the backwash chamber and the filter hole are directly opposite each other.

[0018] The oil collecting tank is provided with a water inlet which is communicated with the backwash chamber.

[0019] By lifting and lowering the separation module and controlling the connecting rod, the oil collecting tank can be driven to move back and forth left and right, so that when the separation module is not separating scum and floating oil, the filter holes can be backwashed to prevent the filter holes from being blocked.

[0020] As a further improvement, a backwash plate is slidably mounted in the backwash chamber, and a hydraulic oil chamber is provided in the oil collecting tank, which contains hydraulic oil; the hydraulic oil chamber includes a horizontal section and a vertical section that are interconnected, the right end of the horizontal section extends to the right side of the oil collecting tank, and a plug is slidably mounted in the horizontal section, a compression spring is provided between the plug and the oil collecting tank, and the compression spring pushes the plug to the right, and the upper end of the vertical section extends to the bottom surface of the backwash chamber; a connecting column is installed at the bottom of the backwash plate, and the connecting column penetrates into the vertical section;

[0021] A push column extending to the left is fixed on the right side of the bottom plate through a mounting block. The push column corresponds to the horizontal section on the left and right. When the oil collecting tank moves to the right, the push column pushes the plug to the left and drives the backwash plate to move upward through hydraulic oil, pushing the liquid in the backwash chamber into the filter hole.

[0022] By utilizing the rightward movement of the oil collecting tank, the backwash plate is driven to move upward through the conduction of the push column, hydraulic oil and connecting column, thereby realizing backwashing without the need for an additional power source and lowering the cost of use.

[0023] As a further improvement, the sewage treatment equipment for automobile parts processing workshop includes a driving mechanism for driving the slag removing assembly to move;

[0024] The driving mechanism includes sprockets arranged in pairs and chains wound around the outside of the sprockets. The fixed plate is fixed on the chain. The chain circulates to drive the slag removing assembly to move from left to right to remove the slag.

[0025] The driving mechanism also includes a limit bar fixed on the inner wall of the processing pool, which extends left and right and is located above the separation module; the end of the fixed plate extends to the bottom of the limit bar, and the limit bar is used to stop the fixed plate to prevent the slag removal assembly from moving upward.

[0026] As a further improvement, there are at least two slag shifting assemblies, and the at least two slag shifting assemblies are arranged at intervals along the chain.

[0027] As a further improvement, a scraper is provided on the right side of the top plate. The scraper is located above the slag storage chamber and is used to scrape off slag on the slag skimmer.

[0028] As a further improvement, a slag storage bent plate is provided on the top of the slag storage chamber.

[0029] As a further improvement, the sewage treatment equipment for automobile parts processing workshop also includes a clear water tank located on the right side of the slag trough. The treatment tank and the clear water tank are connected by a drainage pipe, and the drainage pipe runs through the slag trough.

[0030] The beneficial effects are:

[0031] 1. When the slag-sliding assembly moves rightward, it pushes the slag-oil mixture rightward and onto the bearing surface of the top plate. When the slag-sliding plate is in a vertical position, the bottom of the slag-sliding plate is located below the bearing surface. While pushing the slag-oil mixture onto the bearing surface, the slag-sliding plate itself is pushed in the opposite direction to the left by the top plate. The slag-sliding plate overcomes the force of the first elastic member and swings leftward, pressing the slag-oil mixture beneath the slag-sliding plate. The first elastic member constantly applies a downward and rightward elastic force to the slag-sliding plate, squeezing the slag-oil mixture between the slag-sliding plate and the top plate. The oil flows through the filter holes into the oil collecting trough, and the slag is further pushed rightward by the slag-sliding plate and falls into the slag storage chamber. The sewage treatment equipment for automobile parts processing workshops of the present invention can remove slag from the surface of the treatment tank and simultaneously separate slag and oil. This eliminates the need for separate separation equipment after scraping out all the slag, thereby reducing costs.

[0032] 2. When the slag plate swings to the left and gradually changes to a horizontal state, the slag plate can be pressed by the push plate and the pressure plate, thereby increasing the extrusion force between the slag plate and the top plate and improving the separation effect of slag and floating oil.

[0033] 3. The separation module can float up and down. The first elastic member applies a downward force to the slag removal plate, and the third elastic member applies an upward force to the top plate. After the two are combined, the extrusion force is greater and the separation effect is better.

[0034] 4. By utilizing the lifting and lowering of the separation module and the control of the connecting rod, the oil collecting tank can be driven to move back and forth left and right, so that when the separation module is not separating scum and floating oil, the filter holes can be backwashed to prevent the filter holes from being blocked.

[0035] 5. By utilizing the rightward movement of the oil collecting tank, the backwash plate is driven to move upward through the conduction of the push column, hydraulic oil and connecting column, thereby realizing backwashing. No additional power source is required, and the use cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0057] Embodiments of the sewage treatment equipment for automobile parts processing workshops provided by the present invention:

[0058] like Figures 1 to 11 As shown, the wastewater treatment equipment for automobile parts processing workshop (hereinafter referred to as the wastewater treatment equipment) includes a treatment tank 1, a slag removal assembly 2, a driving mechanism, a slag discharge chute 4, a separation module 5, a third elastic member 61, and a connecting rod 62. The slag discharge chute 4 is located at the right end of the treatment tank 1.

[0059] The treatment pool 1 has a chamber therein for containing liquid. The structure of the treatment pool 1 is prior art and will not be described in detail here.

[0060] The slag-sweeping assembly 2 is used to scrape scum and oil from the surface of the liquid in the treatment tank 1. Specifically, the slag-sweeping assembly 2 moves from left to right, pushing the scum and oil to the right. A drive mechanism is used to drive the movement of the slag-sweeping assembly 2. Two slag-sweeping assemblies 2 are provided. In other embodiments, the number of slag-sweeping assemblies 2 can be increased or decreased.

[0061] like Figure 5 As shown, the slag removing assembly 2 includes a fixing plate 21 , a slag removing plate 22 , a first elastic member 23 , a pressing plate 24 , and a second elastic member 25 .

[0062] The fixed plate 21 is T-shaped and includes a horizontal plate 26 and a vertical plate 27. The horizontal plate 26 extends forward and backward, and its two ends are respectively fixed to the driving mechanism. One end of the vertical plate 27 is fixed to the horizontal plate 26, and the slag plate 22 is hinged to the other end of the vertical plate 27. The hinge axis of the slag plate 22 extends in the front-to-back direction. Here, the first elastic member 23 is a coil spring, which connects the fixed plate 21 and the slag plate 22. The function of the first elastic member 23 is to apply elastic force to the slag plate 22 to keep the slag plate 22 in a vertical state. It should be noted that the vertical state here does not only include the state of being arranged at 90° to the horizontal plane. As long as the whole is in a state of extending up and down, it is a vertical state. When the slag removing assembly 2 moves from left to right, the slag removing plate 22 is located below the fixed plate, pushing the slag and oil.

[0063] Here, the slag shifting plate 22 is an arc-shaped plate. The slag shifting plate 22 is elastic. When the slag shifting assembly 2 moves from left to right, the slag shifting plate 22 protrudes to the left.

[0064] The pressure plate 24 is connected to the horizontal plate 26 via a second elastic member 25. The pressure plate 24 is located on one side of the vertical plate 27. Specifically, the pressure plate 24 has a protruding portion 28. The second elastic member 25 connects the protruding portion 28 and the horizontal plate 26. Here, the second elastic member 25 is a tension spring. When the slag removing assembly 2 moves from left to right, the pressure plate 24 is located on the left side of the vertical plate 27. The second elastic member 25 exerts an upward elastic force on the pressure plate 24, causing the top surface of the pressure plate 24 to be located above the top surface of the horizontal plate 26. The top right side of the pressure plate 24 has a first arc angle 29.

[0065] The front and rear ends of the fixing plate 21 extend to the inner wall of the treatment tank 1 , and the bottom of the pressing plate 24 does not extend to the inner wall of the treatment tank 1 in order to avoid the driving mechanism.

[0066] like Figures 1 to 5 As shown, the drive mechanism includes two drive units arranged front and back and a connecting shaft 31. Each drive unit includes two sprockets 32 and a chain 33. The two sprockets 32 are arranged in the left and right directions. The sprockets 32 are rotatably mounted on the inner wall of the treatment tank 1 around an axis extending front and back. The chain 33 is mounted around the outside of the two sprockets 32. The rotation of the sprockets 32 drives the chain 33 to circulate, wherein the bottom section of the chain 33 moves from left to right. The front and rear ends of the cross plate 26 in the fixed plate 21 are respectively fixed to the two chains 33, and can be fixed to the chains 33 by welding. The two slag removal assemblies 2 are arranged at intervals along the chains 33.

[0067] The connecting shaft 31 connects the sprockets 32 of the two drive units, so that the chains 33 of the two drive units move synchronously. The drive mechanism also includes a motor (not shown in the figure), which drives one of the sprockets 32 to rotate.

[0068] There is a gap between the chain 33 and the inner wall of the treatment tank 1 .

[0069] The driving mechanism also includes a limit bar 34 and a push plate 35. The limit bar 34 prevents the slag removing assembly 2 from moving upward when the slag removing assembly 2 moves above the separation module 5. The push plate 35 drives the pressure plate 24 to press downward on the slag removing plate 22.

[0070] Limiting bars 34 extend forward and backward, fixed to the inner wall of the treatment tank 1, and positioned above the separation module 5. Leftward and rightward, they are located in the gap between the chain 33 and the treatment tank 1. The front and rear ends of the fixed plate 21 extend below the limiting bars 34. When the slag shifting assembly 2 is pressed against the separation module 5, the limiting bars 34 block the fixed plate 21, preventing the slag shifting assembly 2 from being pushed upward.

[0071] The push plate 35 is fixed to the inner wall of the treatment tank 1, and the thickness direction of the push plate 35 is the left-right direction. The push plate 35 is located directly above the separation module 5. The bottom surface of the push plate 35 is flush with the bottom surface of the limit bar 34. A second arc angle 36 is provided on the left side of the bottom of the push plate 35. When the slag removal assembly 2 moves from left to right, the top surface of the fixed plate 21 is flush with the bottom surface of the push plate 35, or the top surface of the fixed plate 21 is located below the bottom surface of the push plate 35. The first arc angle 29 of the pressure plate 24 presses on the second arc angle 36 of the push plate 35, and the push plate 35 drives the pressure plate 24 to move downward.

[0072] like Figures 1 to 9 As shown, the slag chute 4 is located on the right side of the treatment tank 1. It contains two chambers arranged on the left and right: a separation chamber 41 on the left and a slag storage chamber 42 on the right. The separation module 5, the third elastic member 61, and the connecting rod 62 are all located in the separation chamber 41. A slag storage bent plate 43 is fixed within the slag storage chamber 42 to store scum. Two spring support plates 44 are fixed within the separation chamber 41. The two spring support plates 44 are spaced apart in the front-to-back direction, and the space between the two spring support plates 44 allows the connecting rod 62 to pass through.

[0073] The function of the separation module 5 is to separate scum and floating oil, and the separation module 5 comprises a bottom plate 51 , an oil collecting tank 52 , a top plate 53 , a backwash plate 54 , and a backwash driving component.

[0074] The bottom plate 51 is adapted to slide vertically within the separation chamber 41. The bottom plate 51 includes a mounting block 55 on the right side. Two guide slots 56 extending horizontally and vertically through the bottom plate 51 are provided, spaced apart in the front-to-back direction.

[0075] The oil collecting tank 52 has two chambers, one on the left and one on the right: a backwash chamber 57 on the left and an oil collecting chamber 58 on the right. A water inlet 59 and an oil drain 510 are provided on the front and rear sidewalls of the oil collecting tank 52. The water inlet 59 communicates with the backwash chamber 57, while the oil drain 510 communicates with the oil collecting chamber 58. A notch is provided at the bottom right of the oil collecting tank 52 to accommodate the mounting block 55. The water inlet 59 is connected to a water inlet pipe 511, while the oil drain 510 is connected to an oil drain pipe 512.

[0076] The oil sump 52 contains a hydraulic oil chamber containing hydraulic oil. This chamber comprises a interconnected horizontal section 513 and a vertical section 514. The horizontal section 513 extends rightward to the right side of the oil sump 52, while the vertical section 514 extends upward to the bottom of the backwash chamber 57. A compression spring 515 is positioned within the horizontal section 513. The left end of the spring 515 presses against the sidewall of the vertical section 514. A plug 516 is secured to the right end of the spring 515, sealing the horizontal section 513.

[0077] The oil collecting tank 52 is slidably assembled in the guide groove 56 via two sliders 517 , and the sliders 517 are fixed to the bottom of the oil collecting tank 52 .

[0078] A top plate 53 is supported on top of the oil collecting tank 52 and slides vertically within the separation chamber 41. The top surface of the top plate 53 serves as a bearing surface, and is provided with filter holes 518. These filter holes 518 allow the passage of floating oil but not scum, thereby separating the scum from the floating oil. These filter holes 518 correspond vertically with either the backwash chamber 57 or the oil collecting chamber 58, and are aligned vertically with the push plate 35. A sloped surface 519 is provided on the left side of the top plate 53, extending downward and tilted to the left.

[0079] A scraper 520 is fixed to the right side of the top plate 53, and the scraper 520 can scrape off the scum on the slag stripper plate 22. Wherein, the scraper 520 is located above the slag storage chamber 42, and the scraped scum directly falls onto the slag storage bent plate 43 of the slag storage chamber 42.

[0080] The backwash plate 54 is adapted to slide vertically in the backwash chamber 57. The backwash drive component pushes the backwash plate 54 upward when the backwash chamber 57 is aligned with the filter holes 518, causing the liquid in the backwash chamber 57 to impact the filter holes 518, thereby flushing impurities in the filter holes 518 upward.

[0081] The backwash drive components include a connecting column 521 and a pushing column 522. The connecting column 521 is adaptively slidably assembled in the vertical section 514, and the upper end of the connecting column 521 is connected to the backwash plate 54; the pushing column 522 is fixedly installed on the mounting block 55, and the pushing column 522 is opposite to the horizontal section 513 on the left and right. The pushing column 522 can extend into the horizontal section 513 and push the plug 516.

[0082] The lower end of the third elastic member 61 is fixed to the spring support plate 44, and the upper end is fixed to the base plate 51. The third elastic member 61 is a compression spring. There are two connecting rods 62, corresponding one-to-one with the two sliders 517. A hinge shaft 63 is rotatably mounted below the separation chamber 41. The hinge shaft 63 is located on the right side of the separation chamber 41. The lower end of the connecting rod 62 is mounted on the hinge shaft 63, and the upper end of the connecting rod 62 is hinged to the slider 517. When the separation module 5 moves downward, the connecting rod 62 drives the oil collecting tank 52 to slide to the left, so that the oil collecting chamber 58 and the filter hole 518 are vertically opposite each other; when the separation module 5 moves upward, the connecting rod 62 drives the oil collecting tank 52 to slide to the right, so that the backwash chamber 57 and the filter hole 518 are vertically opposite each other, and at the same time, the pushing column 522 pushes the plug 516, and the plug 516 pushes the connecting column 521 and the backwash plate 54 upward through the hydraulic oil to backwash the filter hole 518.

[0083] A clean water tank 7 is arranged on the right side of the slag chute 4 . The clean water tank 7 is connected to the treatment tank 1 through a drainage pipe 8 , which runs through the slag chute 4 .

[0084] Usage process: In the initial state, the separation module 5 is pushed upward to the high position by the third elastic member 61, and the backwash chamber 57 in the oil collecting tank 52 is aligned with the filter hole 518. Figure 10 shown.

[0085] When scraping scum begins, the chain 33 drives the scum removal assembly 2 from left to right. The scum removal plate 22, held in a vertical position by the first elastic member 23, pushes the scum and oil mixture to the right. At this point, the scum removal assembly 2 is in its scum removal stroke. When the scum removal assembly 2 reaches the separation module 5, the fixed plate 21 is restrained by the stop bar 34 and prevents it from moving downward. The scum removal plate 22 of the scum removal assembly 2 presses against the inclined surface 519, forcing the separation module 5 downward. The scum removal plate 22, in turn, swings leftward under the opposing force of the inclined surface 519. The scum removal assembly 2 continues to move rightward, with the fixed plate 21 pressing against the inclined surface 519, further driving the separation module 5 downward. As the separation module 5 moves downward, the oil collecting trough 52 moves leftward, aligning the oil collecting chamber 58 with the filter hole 518. At this point, the scum removal assembly 2 is in its extrusion stroke.

[0086] When the slag shifting assembly 2 continues to move to the right, the fixed plate 21 moves to the top surface of the top plate 53, and the slag shifting plate 22 swings to the left and presses on the top surface of the top plate 53. Since the slag shifting plate 22 itself is arc-shaped, the slag is located between the top surfaces of the slag shifting plate 22 and the top plate 53. The first elastic member 23 exerts a downward force on the slag shifting plate 22, squeezing the slag between the slag shifting plate 22 and the top plate 53. Figure 4 shown.

[0087] When the slag removing assembly 2 continues to move to the right, the push plate 35 pushes the pressure plate 24 downward, and the pressure plate 24 moves downward and presses on the slag removing plate 22, further squeezing the slag between the slag removing plate 22 and the top plate 53, so that the slag and the floating oil are separated. Figure 11 shown.

[0088] The slag removing assembly 2 continues to move to the right, and the slag removing plate 22 remains in contact with the top plate 53. The slag removing plate 22 removes the slag onto the slag storage bent plate 43; the scraper 520 scrapes the slag on the slag removing plate 22 onto the slag storage bent plate 43. The slag removing plate 22 is reset under the action of the first elastic member 23 to carry out the next round of slag removing. After the slag removing assembly 2 is separated from the separation module 5, the separation module 5 moves upward under the action of the third elastic member 61, and the oil collecting tank 52 moves to the right, so that the backwash chamber 57 and the filter hole 518 are vertically aligned; at the same time, the push column 522 pushes into the horizontal section 513 and presses on the plug 516, driving the backwash plate 54 to move upward, flushing the water in the backwash chamber 57 into the filter hole 518, and realizing backwashing.

[0089] In this embodiment, the drive mechanism includes a chain 33, which drives the slag removal assembly 2 to move. Because the chain 33 is flexible, in order to apply a downward force to the separation module 5, the drive mechanism is also provided with a limit bar 34 to stop the fixed plate 21. In other embodiments, a chute can be provided on the inner wall of the treatment tank 1, and the end of the fixed plate 21 extends into the chute, thereby limiting the fixed plate 21.

[0090] In this embodiment, a backwash plate 54 and a backwash driving component are provided to backwash the filter holes 518. In other embodiments, a water pump is provided on the water inlet pipe 511 to pressurize the liquid to backwash the filter holes 518.

[0091] In this embodiment, the slag-sliding assembly 2 includes a pressure plate 24, and the driving mechanism includes a push plate 35. The push plate 35 presses down on the pressure plate 24, which in turn pushes against the slag-sliding plate 22, thereby squeezing out the slag. In other embodiments, the pressure plate 24 and push plate 35 may be omitted, with only the first elastic member 23 applying force to the slag-sliding plate 22.

[0092] In this embodiment, the oil collecting tank 52 has a backwash chamber 57 and an oil collecting chamber 58. In other embodiments, the oil collecting tank 52 may only retain the oil collecting chamber 58.

[0093] In this embodiment, the separation module 5 is slidably assembled in the separation chamber 41 . In other embodiments, the separation module 5 can be fixedly installed in the separation chamber 41 .

[0094] In addition, in the description of this specification, “a plurality of” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.
