Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to wastewater treatment equipment and method for powdered oil production. Background Art

[0002] The main ingredients of powdered fats include hydrogenated vegetable oil, glucose syrup, emulsifiers, etc. Powdered fats are mainly used in the food industry. Powdered fats can be used to make tea raw materials, dairy raw materials, and pastries such as cakes and biscuits, which can improve the quality and taste of the products; powdered fats are also used to make functional powdered fats, such as in baked goods, beverages, health products, etc. They can provide rich nutrients, such as vitamins A, D, E, and polyunsaturated fatty acids (such as DHA and EPA), which have a significant regulatory effect on human health.

[0003] However, in the prior art, when the water content of the scum in the wastewater is high, it is difficult to form a mud layer. The scum is allowed to gather for a long time and then scraped clean at one time. However, if the scum exists for too long, part of the scum will sink back into the water. When the scum gathers too much, the thickness of the scum increases, which causes the scraper mechanism to frequently drive the scraper plate to scrape off the scum. If the scraper machine speed is too fast, it will also stir the water surface, causing part of the scum to sink back into the water, thereby affecting the scraper mechanism to quickly clean the scum inside the scraping area.

[0013] The present invention also provides a method for treating wastewater from powdered oil production, using the wastewater treatment equipment for powdered oil production as described above, comprising the following steps: Step 1: The sewage is transported to the interior of the sewage purification tank through the sewage inlet pipe. The sewage dissolving gas structure is activated to fully mix the dissolved gas water with the sewage in the sewage purification tank, and then released to generate violent agitation and vortex, forming microbubbles with a diameter of about 20-50UM. The microbubbles adhere to the flocs in the raw water, and the overall density of the suspended matter attached with a large number of microbubbles is less than one. Then the flocs and bubbles rise to the liquid surface together to form scum, which gathers on the liquid surface; Step 2: When the wastewater treatment is almost completed, the length of the scraper block is adjusted according to the thickness of the scum on the liquid surface, and the second electric push rod is started to push the moving block to move out of the second installation groove. When the moving block moves, the slider is driven to move along the slide groove. The moving block moves and drives the movable block and the first limit block to move at the same time, so that the first limit block and the second limit block are separated, so that the connecting spring is no longer squeezed and pushes the second limit block to drive the plug rod to move to one side of the movable block. When the limit plate moves to the limit opening, the plug rod is inserted into the jack at one end of the movable block, thereby increasing the length of the scraper block through the movable block, and then starting the second motor to drive the rotating shaft and the rotating wheel to rotate, and the first transmission wheel, the second transmission wheel and the third transmission wheel are driven to rotate through the transmission action of the belt, so that the fixed rod drives the scraper block to rotate and the scum on the water surface is directly contacted, and when the scraper block rotates, it drives the moving block to rotate, so that the scum scraped by the moving block is brought into the scum groove of the collecting block, and the scum is discharged through the sewage slag pipe, and then the purified water is discharged from the sewage drain pipe; Step 3: When the scum is not scraped off in time and the scum on the liquid surface accumulates too much, the first motor is started to drive the threaded rod to rotate along the inner wall of the moving groove, so that the threaded block drives the first electric push rod and the electric telescopic plate to move to the outside of the first installation groove. When the electric telescopic plate moves to between the collecting block and the baffle, the electric telescopic plate is started to extend so that the first filter plate and the second filter plate are exposed. When the electric telescopic plate is extended, the second magnetic block on one side of the electric telescopic plate is magnetically connected to the first magnetic block on one side of the plate, and the positions of the first filter plate and the second filter plate are fixed, so that when the scum on the liquid surface accumulates too much and sinks, it can fall on the first filter plate and the second filter plate to be collected; Step 4: After the purified water is discharged, the electric telescopic block on the left side of the absorption tube is started to contract, so that the electric telescopic block on the left side drives the absorption tube through the third magnetic block and the fourth magnetic block, and bends in the contraction direction of the electric telescopic block on the left side, so that the third magnetic block on the right side of the connecting plate and the fourth magnetic block of the electric telescopic block on the right side are separated. When the electric telescopic block on the right side contracts, the absorption tube is driven to bend through the third magnetic block on the right side of the connecting plate and the fourth magnetic block of the electric telescopic block on the right side, so that the electric telescopic tube moves left and right, so that the absorption tube absorbs the scum remaining on the first filter plate and the second filter plate into the scum tank for collection. When the scum is cleaned, the protective door is rotated and the first electric push rod is contracted so that the threaded block is no longer connected to the electric telescopic plate, and the electric telescopic plate is taken out through the moving port, and the first filter plate and the second filter plate can be cleaned.

[0014] The beneficial effects of the present invention are: (1) The present invention collects excess scum on the liquid surface through the first filter plate and the second filter plate, and cleans the scum on the first filter plate and the second filter plate to the inside of the scum tank through the sewage treatment cleaning structure, so as to improve the rapid cleaning effect of the scum inside the scraping area, and prevent the scum from existing for too long, so that part of the scum will sink back into the water, causing the scum to accumulate at the bottom of the sewage purification tank, thereby affecting the sewage discharge effect of the sewage purification tank; (2) The present invention facilitates increasing the length of the scraping block by moving the moving block. When too much scum accumulates on the liquid surface, the thickness of the scum increases. The moving block facilitates scraping off the accumulated scum. At the same time, it can prevent the scraping mechanism from frequently driving the scraping plate to scrape off the scum, thereby facilitating the scraping effect. It further prevents the scraping block from moving quickly to stir the water surface, thereby causing part of the scum to sink back into the water, thereby further improving the wastewater purification effect.

A first fixed groove is opened on one side of the movable groove and located on the inner wall of the sewage purification box 1, and a first motor 11 is fixedly installed inside the first fixed groove. A threaded rod 12 is transmission-connected to the output end of the first motor 11, and a threaded block 13 is threadedly connected to one end of the threaded rod 12. One side of the threaded block 13 is slidably connected to the inner wall of the movable groove, and a second fixed groove is opened on the other side. A first electric push rod 14 is fixedly installed inside the second fixed groove, and movable openings are opened on both sides of the first installation groove. Slots are opened on both sides of the electric telescopic plate 8, and one end of the first electric push rod 14 passes through the movable opening and is inserted into the slot. A sewage treatment cleaning structure 15 is provided at the bottom end of one side of the collecting block 4.

[0019] The sewage is transported to the interior of the sewage purification tank 1 through the sewage inlet pipe 3. The sewage dissolving gas structure 2 is started to fully mix the dissolved gas water with the sewage in the sewage purification tank 1, and the dissolved gas water is released to generate violent stirring and vortex, forming microbubbles with a diameter of about 20-50UM. The microbubbles are bonded to the flocs in the raw water, and the overall density of the suspended matter attached with a large number of microbubbles is less than one. Then the flocs and bubbles rise to the liquid surface together to form scum, thereby realizing solid-liquid separation. When the scum water content in the wastewater is relatively high, it is difficult to form a mud layer. After a long period of time for the scum to gather, the first motor 11 is started to drive the threaded rod 12 to rotate along the inner wall of the moving groove, so that the threaded block 13 drives the first electric push rod 14 and the electric telescopic plate 8 to move to the outside of the first installation groove. When the electric telescopic plate 8 moves to between the collecting block 4 and the baffle 17, the electric telescopic plate 8 is started to extend, so that the first filter plate 9 and the second filter plate 10 are exposed. According to the liquid level, the filter plate 9 and the second filter plate 10 are exposed. The position of the accumulated scum is adjusted by the first motor 11, the threaded rod 12 and the threaded block 13 to adjust the position of the first filter plate 9, and the position of the second filter plate 10 is adjusted by the extension of the electric telescopic plate 8. When the electric telescopic plate 8 is completely extended, the second magnetic block 19 on one side of the electric telescopic plate 8 is magnetically connected with the first magnetic block 18 on one side of the plate, and the positions of the first filter plate 9 and the second filter plate 10 are fixed, so that when the scum on the liquid surface accumulates too much and sinks, it can fall on the first filter plate 9 and the second filter plate 10 to be collected, preventing the scum from sinking to the bottom of the sewage purification tank 1 and affecting the sewage discharge effect of the sewage purification tank 1. Then, the sewage scraper structure 5 is directly contacted with the water body. When the sewage scraper structure 5 operates, the scraped scum is brought into the scum groove of the collection block 4, and the scum is discharged through the sewage scum discharge pipe 6, and then the purified water is discharged from the sewage drainage pipe 7, and the sludge deposited at the bottom of the sewage purification tank 1 is conveniently discharged through the sludge discharge pipe.

[0020] like Figure 1 to Figure 2 As shown, the sewage scraping structure 5 includes a second motor 51, the output end of the second motor 51 is connected to a rotating shaft 52, one end of the rotating shaft 52 is fixedly installed with a rotating wheel 53, the outer side of the rotating wheel 53 is connected to a belt 54, the inner wall of the other end of the belt 54 is connected to a first transmission wheel 55, the middle part of the belt 54 is connected to a second transmission wheel 56 and a third transmission wheel 57, the middle part of the first transmission wheel 55, the second transmission wheel 56 and the third transmission wheel 57 are all fixedly installed with a fixing rod 58, and the outer side of the fixing rod 58 is fixedly installed with a scraper block 5 9. A first fixed plate is provided between the first transmission wheel 55, the second transmission wheel 56, the third transmission wheel 57 and the fixed rod 58. The middle portion of the first fixed plate is rotatably connected to one end of the fixed rod 58. The other end of the fixed rod 58 is rotatably connected to the second fixed plate. The bottoms of the first fixed plate and the second fixed plate are both fixedly installed on the top of the sewage purification tank 1. The scraper block 59 is located at the top of the sewage purification tank 1. The scraper blocks 59 are distributed in a circular array with the center of the fixed rod 58. A second mounting groove is provided on one side of the scraper block 59, and an adjustment structure is provided inside the second mounting groove.

[0021] By starting the second motor 51, the rotating shaft 52 and the rotating wheel 53 are driven to rotate. Through the transmission effect of the belt 54, the first transmission wheel 55, the second transmission wheel 56 and the third transmission wheel 57 are rotated at the same time, and the fixed rod 58 and the scraper block 59 are driven to rotate. The fixed rod 58 is conveniently fixed by the first fixed plate and the second fixed plate, so that the fixed rod 58 can keep stable when driving the scraper block 59 to rotate. The scraper blocks 59 distributed in a circular array are convenient to bring the scum into the scum groove of the collection block 4, so as to facilitate the purification of wastewater and improve the purification effect.

[0022] like Figures 3 to 6 As shown, the first motor 11 is located at one end of the movable groove near the baffle 17, the threaded rod 12 is rotatably connected to the inner wall of the movable groove near the collecting block 4, a connecting pipe 16 is provided on one side of the sewage dissolving gas structure 2 and located inside the sewage purification box 1, a baffle 17 is fixedly installed at one end of the connecting pipe 16, a first magnetic block 18 is fixedly installed on one side of the baffle 17 and located on the top of the connecting pipe 16, a second magnetic block 19 is fixedly installed on the telescopic end of the electric telescopic plate 8, and the first magnetic block 18 is magnetically connected to the second magnetic block 19.

[0023] The connecting pipe 16 is fixed by the baffle 17, and the sewage dissolved air structure 2 is used to transport the dissolved air into the sewage purification tank 1 through the connecting pipe 16, and the dissolved air is fully mixed with the wastewater, released, and violently stirred and vortexed to form microbubbles. The microbubbles and the flocs in the raw water are mutually bonded, and the overall density of the suspended matter attached with a large number of microbubbles is less than one, and then the flocs and bubbles rise to the liquid surface together to form scum, which gathers on the liquid surface, so that the grease in the wastewater can be separated. When the first motor 11 drives the threaded rod 12 to rotate, the threaded rod 12 rotates along the inner wall of the moving groove, moves along the inner wall of the moving groove through the threaded block 13, and drives the electric telescopic plate 8 to move through the first electric push rod 14, so that the electric telescopic plate 8 moves to the collecting block 4, and the electric telescopic plate 8 is started to extend, so that the first magnetic block 18 is magnetically connected to the second magnetic block 19, and the position of the electric telescopic plate 8 is fixed, so that the first filter plate 9 and the second filter plate 10 can collect the sunken scum, and prevent the scum from falling to the bottom of the sewage purification tank 1 and affecting the sewage discharge effect.

[0024] like Figures 1 to 4 As shown, a movable port is opened on one side of the sewage inlet pipe 3 and located on one side of the sewage purification box 1. The movable port is located at the top of the movable groove. A protective door 20 is arranged inside the movable port. The top of the protective door 20 is rotatably connected to a rotating rod, and both sides of the rotating rod are rotatably connected to the inner wall of the movable port.

[0025] After the water inside the sewage purification tank 1 is drained and the scum on the first filter plate 9 and the second filter plate 10 is cleaned, the first electric push rod 14 is started to retract, so that one end of the first electric push rod 14 is separated from the slot, so that the threaded block 13 is no longer connected to the electric telescopic plate 8, and the protective door 20 is rotated to make the rotating rod rotate along the inner wall of the moving opening, so that the protective door 20 is rotated to a horizontal state to expose the moving opening, and then the electric telescopic plate 8 is taken out from the inside of the first installation groove, and taken out from the inside of the sewage purification tank 1 through the moving opening for easy cleaning and replacement. After cleaning, the new electric telescopic plate 8 is moved from the moving opening to the inside of the sewage purification tank 1, and then placed in the inside of the first installation groove, and the first electric push rod 14 is extended to be plugged into the slots on both sides of the electric telescopic plate 8, so that the electric telescopic plate 8 is installed in the sewage purification tank 1, which is convenient for reuse.

[0026] like Figure 2 , Figure 3 , Figure 5 , Figure 7 As shown, the sewage treatment cleaning structure 15 includes an absorption pipe 151, which is fixedly installed with the collecting block 4, a suction pump 152 is fixedly installed at one end of the collecting block 4, a connecting plate 153 is arranged on one side of the suction pump 152, the middle part of the connecting plate 153 is fixedly installed with the absorption pipe 151, third magnetic blocks 154 are fixedly installed on both sides of the connecting plate 153, a fourth magnetic block 155 is magnetically connected to one side of the third magnetic block 154, an electric telescopic block 156 is fixedly installed on one side of the fourth magnetic block 155, the electric telescopic block 156 is fixedly installed with a fixed block on the side away from the connecting plate 153, and one side of the fixed block is fixedly installed with one side of the collecting block 4, one end of the absorption pipe 151 is located inside the scum groove, and the other end passes through one side of the collecting block 4 and extends to the outside of the collecting block 4, the suction pump 152 is located outside the collecting block 4, the absorption pipe 151 is made of an elastic telescopic tube, the electric telescopic block 156 is in an inclined state, and is symmetrically arranged around the center of the connecting plate 153.

[0027] By starting the suction pump 152, the absorption tube 151 absorbs the scum on the first filter plate 9 and the second filter plate 10 into the scum tank, and then the electric telescopic block 156 on the left side of the absorption tube 151 is started to contract, so that the electric telescopic block 156 on the left side drives the absorption tube 151 through the third magnetic block 154 and the fourth magnetic block 155, and bends in the contraction direction of the electric telescopic block 156 on the left side, so that the third magnetic block 154 on the right side of the connecting plate 153 and the fourth magnetic block 155 of the electric telescopic block 156 on the right side are separated. When the electric telescopic block 156 on the right side contracts, the absorption tube 151 is bent through the third magnetic block 154 on the right side of the connecting plate 153 and the fourth magnetic block 155 of the electric telescopic block 156 on the right side. Since the material of the absorption tube 151 is an elastic telescopic tube, the electric telescopic block 156 moves left and right to expand the cleaning range, so that the absorption tube 151 cleans the scum remaining on the first filter plate 9 and the second filter plate 10 more quickly, thereby improving the efficiency of wastewater treatment.

[0028] like Figure 1 , Figure 2 , Figure 8 As shown, the adjustment structure includes a moving block 21, a movable groove is opened on one side of the moving block 21, a second electric push rod 22 is fixedly installed inside the movable groove, first limit blocks 23 are fixedly installed on both ends of one side of the moving block 21, a second limit block 24 is arranged at the bottom of the first limit block 23, a limit plate 25 is fixedly installed on one side of the second limit block 24, an insertion rod 26 is fixedly installed on the bottom of the second limit block 24, a connecting spring is fixedly installed on one side of the insertion rod 26, a movable block 27 is fixedly installed on one side of the moving block 21 and located on the side of the first limit block 23, a socket is opened at one end of the movable block 27, and the insertion rod 26 is plugged into the socket.

[0029] When the second electric push rod 22 is started, the moving block 21 is pushed to move out of the second installation groove. When the moving block 21 moves, the sliding block 28 is driven to move along the sliding groove. The movement of the moving block 21 drives the movable block 27 and the first limit block 23 to move at the same time, so that the first limit block 23 and the second limit block 24 are separated, so that the connecting spring is no longer squeezed, and the second limit block 24 is pushed to drive the plug 26 to move to one side of the movable block 27. When the limit plate 25 moves to the limit opening, the plug 26 is inserted into the jack at one end of the movable block 27, so that the length of the scraper block 59 is increased by the moving block 21, so that the scraper block 59 can process scum of different thicknesses and prevent excessive accumulation of scum. The scraper block 59 needs to rotate back and forth frequently to perform the scum scraping operation. When the scraper block 59 rotates too fast, it will stir the water surface, thereby causing part of the scum to sink back into the water, so that the scum is not processed cleanly enough, affecting the quick cleaning effect of the scum.

[0030] like Figure 2 , Figure 8As shown, one end of the moving block 21 is located outside the second mounting groove, and the other end is located inside the second mounting groove. The moving block 21 is located inside the second mounting groove, and sliders 28 are fixedly installed on both sides thereof. Slide grooves are provided on the inner walls on both sides of the second mounting groove, and the sliders 28 are slidably connected with the slide grooves. One end of the second electric push rod 22 passes through the movable groove and is fixedly installed on the inner wall of the second mounting groove. The first limit block 23 and the second limit block 24 are close to each other and the side in contact with each other is an inclined surface. Limiting openings are provided on both sides of the scraper block 59, and the second limit block 24 extends through the limiting opening to the outside of the scraper block 59. The connecting spring is located at the bottom of the limiting opening, and one end of the connecting spring is fixedly installed on the inner wall of the second mounting groove. The limiting plate 25 is located on the left and right sides of the scraper block 59.

[0031] The second electric push rod 22 pushes the moving block 21 to move outside the second mounting groove. When the moving block 21 moves, it drives the slider 28 to move along the slide groove. The slider 28 is used to limit the moving block 21. When the moving block 21 moves, it drives the first limit block 23 and the movable block 27 to move upward. The plug rod 26 is pushed to move toward the movable block 27 through the limit opening through the connecting spring, so that the second limit block 24 moves toward the inside of the second mounting groove through the limit opening, so that the plug rod 26 is plugged into the jack at one end of the movable block 27, so that the moving block 21 is fixed, so that when the scraping block 59 drives the moving block 21 to rotate, the moving block 21 remains stable, the scum scraping effect is improved, and it is easy to use.

[0032] The present invention also provides a method for treating wastewater from powdered oil production, using the above-mentioned wastewater treatment equipment for powdered oil production, comprising the following steps: Step 1: The sewage is transported to the interior of the sewage purification tank 1 through the sewage inlet pipe 3, and the sewage dissolving gas structure 2 is started to fully mix the dissolved gas water with the sewage in the sewage purification tank 1, and release it, generating violent agitation and vortex, forming microbubbles with a diameter of about 20-50UM, and the microbubbles are mutually bonded with the flocs in the raw water, and the overall density of the suspended matter attached with a large number of microbubbles is less than one, and then the flocs and bubbles rise to the liquid surface together, forming scum, and gathering on the liquid surface; Step 2: When the wastewater treatment is almost completed, the length of the scraper block 59 is adjusted according to the thickness of the scum on the liquid surface, and the second electric push rod 22 is started to push the moving block 21 to move out of the second installation groove. When the moving block 21 moves, it drives the slider 28 to move along the slide groove. The movement of the moving block 21 drives the movable block 27 and the first limit block 23 to move at the same time, so that the first limit block 23 and the second limit block 24 are separated, so that the connecting spring is no longer squeezed and pushes the second limit block 24 to drive the plug 26 to move to one side of the movable block 27. When the limit plate 25 moves to the limit opening, the plug 26 is inserted into the movable block 27. The inside of the jack at the end is inserted into the scraper block 59, thereby increasing the length of the scraper block 59 through the moving block 21, and then starting the second motor 51 to drive the rotating shaft 52 and the rotating wheel 53 to rotate, and the first transmission wheel 55, the second transmission wheel 56 and the third transmission wheel 57 are driven to rotate through the transmission action of the belt 54, so that the fixed rod 58 drives the scraper block 59 to rotate and directly contact the scum on the water surface. When the scraper block 59 rotates, it drives the moving block 21 to rotate, so that the scum scraped by the moving block 21 is brought into the scum groove of the collecting block 4, and the scum is discharged through the sewage scum discharge pipe 6, and then the purified water is discharged from the sewage drain pipe 7; Step 3: At the same time, when the scum is not scraped off in time and causes excessive accumulation of scum on the liquid surface, the first motor 11 is started to drive the threaded rod 12 to rotate along the inner wall of the moving groove, so that the threaded block 13 drives the first electric push rod 14 and the electric telescopic plate 8 to move to the outside of the first installation groove. When the electric telescopic plate 8 moves to between the collecting block 4 and the baffle 17, the electric telescopic plate 8 is started to extend, so that the first filter plate 9 and the second filter plate 10 are exposed. When the electric telescopic plate 8 is extended, the second magnetic block 19 on one side of the electric telescopic plate 8 is magnetically connected to the first magnetic block 18 on one side of the baffle 17, and the positions of the first filter plate 9 and the second filter plate 10 are fixed, so that when the scum on the liquid surface accumulates too much and sinks, it can fall on the first filter plate 9 and the second filter plate 10 to be collected; Step 4: After the purified water is discharged, the electric telescopic block 156 on the left side of the absorption tube 151 is started to contract, so that the electric telescopic block 156 on the left side drives the absorption tube 151 through the third magnetic block 154 and the fourth magnetic block 155, and bends in the contraction direction of the electric telescopic block 156 on the left side, so that the third magnetic block 154 on the right side of the connecting plate 153 and the fourth magnetic block 155 of the electric telescopic block 156 on the right side are separated. When the electric telescopic block 156 on the right side contracts, the third magnetic block 154 on the right side of the connecting plate 153 and the fourth magnetic block 155 are connected. The fourth magnetic block 155 of the electric telescopic block 156 on the right side drives the absorption tube 151 to bend, so that the electric telescopic block 156 moves left and right, so that the absorption tube 151 absorbs the scum remaining on the first filter plate 9 and the second filter plate 10 into the scum tank for collection. When the scum is cleaned, the protective door 20 is rotated, and the first electric push rod 14 is contracted so that the threaded block 13 is no longer connected to the electric telescopic plate 8. The electric telescopic plate 8 is taken out through the moving port, and the first filter plate 9 and the second filter plate 10 can be cleaned.

[0033] Working principle: when in use, the sewage is transported to the interior of the sewage purification box 1 through the sewage inlet pipe 3, and the sewage dissolving gas structure 2 is started to fully mix the dissolved gas water and the sewage in the sewage purification box 1, and release it, generating violent stirring and vortex, forming microbubbles with a diameter of about 20-50UM, and the microbubbles are mutually bonded with the flocs in the raw water, and the overall density of the suspended matter attached with a large number of microbubbles is less than one, and then the flocs and bubbles rise to the liquid surface together, forming scum, and gathering on the liquid surface. When the wastewater treatment is almost completed, the length of the scraper block 59 is adjusted according to the thickness of the scum on the liquid surface, and the second electric push rod 22 is started to push the moving block 21 to move out of the second installation groove. When the moving block 21 moves, it drives the slider 28 to move along the slide groove, and the moving block 21 moves and drives the movable block 27 and the first limit block 23 to move at the same time, so that the first limit block 23 and the second limit block 24 is away from each other, so that the connecting spring is no longer squeezed to push the second limit block 24 to drive the plug rod 26 to move to the side of the movable block 27. When the limit plate 25 moves to the limit opening, the plug rod 26 is inserted into the jack at one end of the movable block 27 to fix the movable block 21, thereby increasing the length of the scraper block 59 through the movable block 21, and then starting the second motor 51 to drive the rotating shaft 52 and the rotating wheel 53 to rotate, and the first transmission wheel 55, the second transmission wheel 56 and the third transmission wheel 57 are driven to rotate through the transmission action of the belt 54, so that the fixed rod 58 drives the scraper block 59 to rotate and directly contact the scum on the water surface. When the scraper block 59 rotates, it drives the movable block 21 to rotate, so that the scum scraped by the movable block 21 is brought into the scum groove of the collecting block 4, and the scum is discharged through the sewage scum discharge pipe 6, and then the purified water is discharged from the sewage drain pipe 7.

[0034] At the same time, when the scum is not scraped off in time and causes excessive accumulation of scum on the liquid surface, the first motor 11 is started to drive the threaded rod 12 to rotate along the inner wall of the moving groove, so that the threaded block 13 drives the first electric push rod 14 and the electric telescopic plate 8 to move to the outside of the first installation groove. When the electric telescopic plate 8 moves to between the collecting block 4 and the baffle 17, the electric telescopic plate 8 is started to extend, so that the first filter plate 9 and the second filter plate 10 are exposed. When the electric telescopic plate 8 completes the extension, the second magnetic block 19 on one side of the electric telescopic plate 8 is magnetically connected to the first magnetic block 18 on one side of the plate, so that the positions of the first filter plate 9 and the second filter plate 10 are fixed, so that when the scum on the liquid surface accumulates too much and sinks, it can fall on the first filter plate 9 and the second filter plate 10 to be collected. When the purified water is discharged, the electric telescopic block 156 on the left side of the absorption pipe 151 is started to contract, so that the electric telescopic block 156 on the left side passes through the third The magnetic block 154 and the fourth magnetic block 155 drive the absorption tube 151 to bend in the contraction direction of the electric telescopic block 156 on the left side, so that the third magnetic block 154 on the right side of the connecting plate 153 is separated from the fourth magnetic block 155 of the electric telescopic block 156 on the right side. When the electric telescopic block 156 on the right side contracts, the absorption tube 151 is driven to bend by the third magnetic block 154 on the right side of the connecting plate 153 and the fourth magnetic block 155 of the electric telescopic block 156 on the right side, so that the electric telescopic block 156 moves left and right, so that the absorption tube 151 absorbs the scum remaining on the first filter plate 9 and the second filter plate 10 into the scum tank for collection. When the scum is cleaned, the protective door 20 is rotated to contract the first electric push rod 14 so that the threaded block 13 is no longer connected to the electric telescopic plate 8, and the electric telescopic plate 8 is taken out through the moving port, and the first filter plate 9 and the second filter plate 10 can be cleaned.
