Description

Technical Field

[0001] The present invention belongs to the technical field of wastewater treatment, and particularly relates to a wastewater treatment device and method for the production of powdered oil and fat. Background Art

[0002] The main components of powdered oil and fat include hydrogenated vegetable oil, glucose syrup, emulsifier, etc. Powdered oil and fat are mainly used in the food industry. It can be used to make tea drink raw materials, dairy raw materials, and make pastries such as cakes and biscuits, which can improve the quality and taste of products; powdered oil and fat are also used to make functional powdered oil and fat, for example, in the fields of baked foods, beverages, health products, etc. They can provide rich nutritional components such as vitamins A, D, E, and polyunsaturated fatty acids (such as DHA and EPA), and these components 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 relatively large, it is difficult to form a mud layer. After a long period of time, the scum is allowed to accumulate and then scraped clean at one time. However, if the scum exists for too long, a part of the scum will sink back into the water. When the scum accumulates too much, the thickness of the scum increases, resulting in the need for the slag scraping mechanism to frequently drive the slag scraping plate to perform the slag scraping operation. If the speed of the slag scraper is too fast, it will also stir the water surface, causing a part of the scum to sink back into the water, thus affecting the rapid cleaning effect of the slag scraping mechanism on the scum inside the slag scraping area.

The connecting spring is located at the bottom of the limit openings and one end of it is fixedly installed with the inner wall of the second installation groove. The limit plates are located on the left and right sides of the scraping block.

[0014] The present invention also provides a method for treating wastewater used in the production of powder grease, using the wastewater treatment equipment for the production of powder grease described in any one of the above, including the following steps:

[0015] Step 1: Transport the sewage into the interior of the sewage purification tank through the sewage inlet pipe. By starting the sewage dissolved air structure, make the dissolved air water fully mix with the wastewater inside the sewage purification tank, release it, generate intense agitation and eddies, and form microbubbles with a diameter of about 20 - 50 UM. These 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 accumulates on the liquid surface;

[0016] Step 2: When the wastewater treatment is almost completed, adjust the length of the scraping block according to the thickness of the scum on the liquid surface. Start the second electric push rod to push the moving block out of the second installation groove. When the moving block moves, it drives the slider to move along the sliding groove. At the same time when the moving block moves, it drives the movable block and the first limiting block to move, so that the first limiting block and the second limiting block move away from each other, and the connecting spring is no longer squeezed to push the second limiting block to drive the insertion rod to move towards the movable block side. When the limiting plate moves to the limiting port, the insertion rod is inserted into the jack at one end of the movable block, thereby increasing the length of the scraping block through the moving block. Then start the second motor to drive the rotating shaft and the rotating wheel to rotate. Through the transmission of the belt, drive the first transmission wheel, the second transmission wheel and the third transmission wheel to rotate, so that the fixed rod drives the scraping block to rotate and directly contact the scum on the water surface. When the scraping 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 discharge pipe. Then the purified water is discharged through the sewage discharge pipe;

[0017] Step 3: At the same time, when the scum is not scraped in time and too much scum accumulates on the liquid surface, start the first motor 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 outside the first installation groove. When the electric telescopic plate moves between the collecting block and the baffle, start the electric telescopic plate to extend, so that the first filter plate and the second filter plate are exposed. When the electric telescopic plate finishes extending, make the second magnetic block on one side of the electric telescopic plate magnetically connect with the first magnetic block on one side of the baffle to fix the positions of the first filter plate and the second filter plate. Thus, when too much scum on the liquid surface accumulates and sinks, it can fall on the first filter plate and the second filter plate for collection;

[0018] Step 4: After the purified water is discharged, start to contract the electric telescopic block on the left side of the absorption tube, so that the electric telescopic block on the left drives the absorption tube through the third magnetic block and the fourth magnetic block, and bends the absorption tube in the contraction direction of the electric telescopic block on the left, so that the third magnetic block on the right side of the connecting plate is separated from the fourth magnetic block of the electric telescopic block on the right. When the electric telescopic block on the right contracts, the absorption tube is bent by 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, so that the electric telescopic tube moves left and right, and the absorption tube absorbs the residual scum on the first filter plate and the second filter plate into the scum tank for collection. After the scum is cleaned, rotate the protective door, and contract the first electric push rod, so that the threaded block is no longer connected to the electric telescopic plate, and take out the electric telescopic plate through the moving port, and clean the first filter plate and the second filter plate.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) The present invention collects the scum with too much liquid level aggregation on the first filter plate and the second filter plate, and cleans the scum on the first filter plate and the second filter plate into the inside of the scum tank through the sewage treatment and cleaning structure for unified treatment, improving the rapid cleaning effect of the scum in the slag scraping area, and preventing part of the scum from sinking back into the water when the scum exists for too long, so that the scum accumulates at the bottom of the sewage purification tank, thus affecting the sewage discharge effect of the sewage purification tank;

[0021] (2) Through the movement of the moving block, the present invention facilitates increasing the length of the scraping block. When there is too much scum aggregated on the liquid level, the thickness of the scum increases. The moving block facilitates scraping the aggregated scum, and at the same time can prevent the slag scraping mechanism from frequently driving the slag scraping plate to perform slag scraping operations, facilitating the slag scraping effect, further preventing the rapid movement of the scraping block from stirring the water surface, resulting in part of the scum sinking back into the water, and further improving the wastewater purification effect.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] The present invention provides a wastewater treatment device for the production of powder grease, as Figures 1 to 6As shown in the figure, it includes a sewage purification tank 1. A sewage aeration structure 2 is arranged on one side of the sewage purification tank 1. A sewage inlet pipe 3 is arranged at the top end of the front side of the sewage purification tank 1. A plurality of sludge discharge pipes are arranged at the bottom end of the front side of the sewage purification tank 1. A collection block 4 is arranged on one side inside the sewage purification tank 1. Both sides of the collection block 4 are installed with the inner wall of the sewage purification tank 1. A scum tank is opened inside the collection block 4. A sewage scraping structure 5 is arranged at the top of the collection block 4 and located at the top of the sewage purification tank 1. A sewage slag discharge pipe 6 is arranged on one side of the collection block 4 and located at the front side of the sewage purification tank 1. A sewage drain pipe 7 is arranged on one side of the sewage slag discharge pipe 6. A first installation groove is opened at the bottom of the collection block 4. An electric telescopic plate 8 is arranged inside the first installation groove. A first filter plate 9 is fixedly installed at the top of the electric telescopic block 156. A second filter plate 10 is fixedly installed at the top of the telescopic end of the electric telescopic plate 8. Moving grooves are opened on both sides of the wall of the collection block 4. A first fixing groove is opened on the inner wall of the sewage purification tank 1 on one side of the moving groove. A first motor 11 is fixedly installed inside the first fixing groove. The output end of the first motor 11 is drivingly connected with a threaded rod 12. One end of the threaded rod 12 is threadedly connected with a threaded block 13. One side of the threaded block 13 is slidably connected with the inner wall of the moving groove, and a second fixing groove is opened on the other side thereof. A first electric push rod 14 is fixedly installed inside the second fixing groove. Activity openings are opened on both sides of the first installation groove. Slots are opened on both sides of the electric telescopic plate 8. One end of the first electric push rod 14 passes through the activity opening and is inserted into the slot. A sewage treatment and cleaning structure 15 is arranged at the bottom end of one side of the collection block 4.

[0033] The sewage is transported into the interior of the sewage purification tank 1 through the sewage inlet pipe 3. By starting the sewage air-dissolving structure 2, the air-dissolved water and the wastewater are fully mixed and released inside the sewage purification tank 1, generating intense agitation and eddies, forming microbubbles with a diameter of about 20 - 50 UM. These 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 the bubbles rise to the liquid surface together to form scum, achieving solid-liquid separation. When the moisture content of the scum in the wastewater is relatively high and it is difficult to form a sludge layer, after allowing the scum to accumulate for a long period of time, start the first motor 11 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 outward from the first installation groove. When the electric telescopic plate 8 moves between the collection block 4 and the baffle 17, start the electric telescopic plate 8 to extend, so that the first filter plate 9 and the second filter plate 10 are exposed. According to the position of the scum accumulated on the liquid surface, adjust the position of the first filter plate 9 through the first motor 11, the threaded rod 12 and the threaded block 13, and adjust the position of the second filter plate 10 through the telescoping of the electric telescopic plate 8. When the electric telescopic plate 8 finishes extending, make the second magnetic block 19 on one side of the electric telescopic plate 8 magnetically connected to the first magnetic block 18 on one side of the baffle, fixing the positions of the first filter plate 9 and the second filter plate 10. Thus, when too much scum accumulated on the liquid surface sinks, it can fall onto the first filter plate 9 and the second filter plate 10 for collection, 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 scum scraping structure 5 is in direct contact with the water body. When the sewage scum scraping structure 5 operates to scrape the scum into the scum groove of the collection block 4, the scum is discharged through the sewage slag discharge pipe 6, and the purified water is discharged through the sewage discharge pipe 7. The sludge deposited at the bottom of the sewage purification tank 1 is discharged through the sludge discharge pipe for easy discharge.

[0034] As Figures 1 to 2 shown, the sewage scum scraping structure 5 includes a second motor 51. The output end of the second motor 51 is drivingly connected to a rotating shaft 52. One end of the rotating shaft 52 is fixedly installed with a rotating wheel 53. The outside of the rotating wheel 53 is drivingly connected to a belt 54. The inner wall of the other end of the belt 54 is drivingly connected to a first driving wheel 55. The middle of the belt 54 is drivingly connected to a second driving wheel 56 and a third driving wheel 57. A fixed rod 58 is fixedly installed in the middle of each of the first driving wheel 55, the second driving wheel 56 and the third driving wheel 57. A scraping block 59 is fixedly installed on the outside of the fixed rod 58. A first fixing plate is provided between the first driving wheel 55, the second driving wheel 56, the third driving wheel 57 and the fixed rod 58. The middle of the first fixing plate is rotatably connected to one end of the fixed rod 58. The other end of the fixed rod 58 is rotatably connected to a second fixing plate. The bottoms of the first fixing plate and the second fixing plate are fixedly installed on the top of the sewage purification tank 1. The scraping block 59 is located at the top end inside the sewage purification tank 1. The scraping blocks 59 are distributed in a circular array centered on the fixed rod 58. A second installation groove is opened on one side of the scraping block 59, and an adjusting structure is provided inside the second installation groove.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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 up, start the first electric push rod 14 to contract, so that one end of the first electric push rod 14 is separated from the slot, and the threaded block 13 is no longer connected to the electric telescopic plate 8. By rotating the protective door 20, the rotating rod rotates along the inner wall of the moving port, so that the protective door 20 rotates to the horizontal state to expose the moving port. Then, take out the electric telescopic plate 8 from the inside of the first installation groove and take it out of the sewage purification tank 1 through the moving port for easy cleaning and replacement. After cleaning, move the new electric telescopic plate 8 from the moving port into the sewage purification tank 1 and then place it inside the first installation groove. Insert the first electric push rod 14 to extend and plug into the slots on both sides of the electric telescopic plate 8, so that the electric telescopic plate 8 is installed inside the sewage purification tank 1 for reuse.

[0040] As Figure 2 , Figure 3 , Figure 5 , Figure 7 shown, the sewage treatment and cleaning structure 15 includes an absorption pipe 151. The absorption pipe 151 is fixedly installed with the collection block 4. One end of the collection block 4 is fixedly installed with a suction pump 152. A connecting plate 153 is arranged on one side of the suction pump 152. The middle 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. A fixed block is fixedly installed on the side of the electric telescopic block 156 away from the connecting plate 153. One side of the fixed block is fixedly installed with one side of the collection block 4. One end of the absorption pipe 151 is located inside the scum tank, and the other end passes through one side of the collection block 4 and extends to the outside of the collection block 4. The suction pump 152 is located outside the collection block 4. The absorption pipe 151 is made of an elastic telescopic pipe. The electric telescopic block 156 is in an inclined state and is symmetrically arranged with the center of the connecting plate 153.

[0041] 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. 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 drives the absorption tube 151 through the third magnetic block 154 and the fourth magnetic block 155 to bend in the contraction direction of the electric telescopic block 156 on the left. As a result, 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. When the electric telescopic block 156 on the right contracts, the absorption tube 151 is driven to bend 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. 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, enabling the absorption tube 151 to clean the residual scum on the first filter plate 9 and the second filter plate 10 more quickly, thereby improving the efficiency of wastewater treatment.

[0042] As Figure 1 , Figure 2 , Figure 8 shown, the adjustment structure includes a moving block 21. An activity groove is formed on one side of the moving block 21, and a second electric push rod 22 is fixedly installed inside the activity groove. Both ends on one side of the moving block 21 are fixedly installed with first limit blocks 23. 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. A plug rod 26 is fixedly installed at the bottom of the second limit block 24. A connecting spring is fixedly installed on one side of the plug rod 26. An activity block 27 is fixedly installed on one side of the moving block 21 and located on one side of the first limit block 23. An insertion hole is formed at one end of the activity block 27, and the plug rod 26 is inserted into the insertion hole.

[0043] Start the second electric push rod 22 to push the moving block 21 out of the second installation groove. When the moving block 21 moves, it drives the slider 28 to move along the sliding groove. When the moving block 21 moves, it also drives the activity block 27 and the first limit block 23 to move, so that the first limit block 23 and the second limit block 24 move away from each other, and the connecting spring is no longer squeezed. Push the second limit block 24 to drive the plug rod 26 to move towards one side of the activity block 27. When the limit plate 25 moves to the limit port, the plug rod 26 is inserted into the insertion hole at one end of the activity block 27, thereby increasing the length of the scraping block 59 through the moving block 21, facilitating the scraping block 59 to process scum with different thicknesses, preventing excessive accumulation of scum. The scraping block 59 needs to rotate back and forth frequently for scum scraping operations. When the rotation speed of the scraping block 59 is too fast, it will stir the water surface, causing some scum to sink back into the water, resulting in incomplete treatment of the scum and affecting the quick cleaning effect of the scum.

[0044] As Figure 2 , Figure 8As shown in the figure, one end of the moving block 21 is located outside the second installation groove, and the other end is located inside the second installation groove. On both sides of the moving block 21 located inside the second installation groove, sliding blocks 28 are fixedly installed. On both inner walls of the second installation groove, sliding grooves are provided, and the sliding blocks 28 are slidably connected to the sliding 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 installation groove. The side of the first limiting block 23 close to the second limiting block 24 is in contact, and the contact side is an inclined surface. Limiting ports are provided on both sides of the scraping block 59. The second limiting block 24 passes through the limiting ports and extends to the outside of the scraping block 59. The connecting spring is located at the bottom of the limiting ports, and one end of the connecting spring is fixedly installed on the inner wall of the second installation groove. The limiting plates 25 are located on the left and right sides of the scraping block 59.

[0045] The second electric push rod 22 is used to push the moving block 21 to move towards the outside of the second installation groove. When the moving block 21 moves, it drives the sliding blocks 28 to move along the sliding grooves. The sliding blocks 28 are convenient for limiting the moving block 21. When the moving block 21 moves, it drives the first limiting block 23 and the movable block 27 to move upward. Under the action of the connecting spring, the insertion rod 26 is pushed to move towards the movable block 27, so that the second limiting block 24 moves towards the inside of the second installation groove through the limiting ports, thereby facilitating the insertion of the insertion rod 26 into the jack at one end of the movable block 27, fixing the moving block 21. When the scraping block 59 drives the moving block 21 to rotate, it is convenient to keep the moving block 21 stable, improve the effect of scum scraping, and facilitate use.

[0046] The present invention also provides a wastewater treatment method for powder grease production, using the above-mentioned wastewater treatment equipment for powder grease production, including the following steps:

[0047] Step 1: The sewage is conveyed into the interior of the sewage purification tank 1 through the sewage inlet pipe 3. By starting the sewage dissolved air structure 2, the dissolved air water and the wastewater are fully mixed and released inside the sewage purification tank 1, generating violent agitation and eddy currents, forming microbubbles with a diameter of about 20 - 50 UM. These 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 accumulates on the liquid surface;

[0048] Step 2: When the wastewater treatment is almost completed, adjust the length of the scraping block 59 according to the thickness of the scum on the liquid surface. Start the second electric push rod 22 to push the moving block 21 out of the second installation groove. When the moving block 21 moves, it drives the slider 28 to move along the sliding groove. When the moving block 21 moves, it also drives the movable block 27 and the first limiting block 23 to move, so that the first limiting block 23 and the second limiting block 24 move away from each other, and the connecting spring is no longer squeezed, which pushes the second limiting block 24 to drive the insertion rod 26 to move towards the movable block 27. When the limiting plate 25 moves to the limiting port, the insertion rod 26 is inserted into the jack at one end of the movable block 27, thereby increasing the length of the scraping block 59 through the moving block 21. Then start the second motor 51 to drive the rotating shaft 52 and the rotating wheel 53 to rotate. Through the transmission of the belt 54, it drives the first transmission wheel 55, the second transmission wheel 56 and the third transmission wheel 57 to rotate, so that the fixed rod 58 drives the scraping block 59 to rotate and directly contact the scum on the water surface. When the scraping 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 slag discharge pipe 6. Then the purified water is discharged through the sewage discharge pipe 7;

[0049] Step 3: At the same time, when the scum is not scraped in time and too much scum accumulates on the liquid surface, start the first motor 11 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 outside the first installation groove. When the electric telescopic plate 8 moves between the collecting block 4 and the baffle 17, start the electric telescopic plate 8 to extend, so that the first filter plate 9 and the second filter plate 10 are exposed. After the electric telescopic plate 8 finishes extending, make the second magnetic block 19 on one side of the electric telescopic plate 8 magnetically connected to the first magnetic block 18 on one side of the baffle 17 to fix the positions of the first filter plate 9 and the second filter plate 10. Thus, when too much scum on the liquid surface accumulates and sinks, it can fall on the first filter plate 9 and the second filter plate 10 for collection;

[0050] 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 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, 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. When the electric telescopic block 156 on the right contracts, the absorption tube 151 is driven to bend 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, so that the electric telescopic block 156 moves left and right, and the absorption tube 151 absorbs the residual scum on the first filter plate 9 and the second filter plate 10 into the scum tank for collection. When the scum cleaning is completed, 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, 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.

[0051] Working principle: When in use, the sewage is transported into the interior of the sewage purification tank 1 through the sewage inlet pipe 3. By starting the sewage dissolved air structure 2 inside the sewage purification tank 1, the dissolved air water and the wastewater are fully mixed and released, generating violent agitation and eddies, forming microbubbles with a diameter of about 20 - 50 UM. These microbubbles adhere to the flocs in the raw water, and the suspended matter attached with a large number of microbubbles has an overall density less than one. Then the flocs and bubbles rise to the liquid surface together to form scum, which accumulates on the liquid surface. When the wastewater treatment is almost completed, the length of the scraping block 59 is adjusted according to the thickness of the scum on the liquid surface. 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 sliding groove. When the moving block 21 moves, it also drives the movable block 27 and the first limiting block 23 to move, so that the first limiting block 23 and the second limiting block 24 move away from each other, and the connecting spring is no longer squeezed to push the second limiting block 24 to drive the insertion rod 26 to move towards the movable block 27. When the limiting plate 25 moves to the limiting port, the insertion rod 26 is inserted into the jack at one end of the movable block 27 to fix the moving block 21, so as to increase the length of the scraping block 59 through the moving block 21. Then the second motor 51 is started to drive the rotating shaft 52 and the rotating wheel 53 to rotate. Through the transmission of the belt 54, the first transmission wheel 55, the second transmission wheel 56 and the third transmission wheel 57 are driven to rotate, so that the fixed rod 58 drives the scraping block 59 to rotate and directly contact the scum on the water surface. When the scraping 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 tank of the collecting block 4, and the scum is discharged through the sewage slag discharge pipe 6. Then the purified water is discharged through the sewage discharge pipe 7.

[0052] Meanwhile, when too much scum accumulates on the liquid surface due to the failure to scrape the scum in time, 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 outward from the first installation groove. When the electric telescopic plate 8 moves between the collection 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. After the electric telescopic plate 8 finishes extending, 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 plate to fix the positions of the first filter plate 9 and the second filter plate 10. Thus, 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 for collection. After the purified water is discharged, by starting the contraction of the electric telescopic block 156 on the left side of the absorption tube 151, 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 to bend in the contraction direction of the electric telescopic block 156 on the left side. As a result, 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 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. Thus, the electric telescopic block 156 moves left and right, so that the absorption tube 151 absorbs the residual scum on the first filter plate 9 and the second filter plate 10 into the scum tank for collection. After the scum is cleaned up, the protective door 20 is rotated. By contracting the first electric push rod 14, 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.

A wastewater treatment method for the production of powder grease, characterized in that, When using the wastewater treatment equipment for the production of powder grease according to any one of claims 1 to 7, it is characterized in that it includes the following steps: Step 1: Convey the sewage into the sewage purification tank through the sewage inlet pipe. By starting the sewage aeration structure, the dissolved air water and the wastewater are fully mixed and released inside the sewage purification tank, generating violent agitation and eddy currents, forming microbubbles with a diameter of 20 - 50 UM. These microbubbles adhere to the flocs in the raw water. 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, forming scum and aggregating on the liquid surface. Step 2: When the wastewater treatment is almost completed, adjust the length of the scraping block according to the thickness of the scum on the liquid surface. Start the second electric push rod to push the moving block out of the second installation groove. When the moving block moves, it drives the slider to move along the sliding groove. While the moving block moves, it also drives the movable block and the first limiting block to move, so that the first limiting block and the second limiting block move away from each other, and the connecting spring is no longer squeezed, which pushes the second limiting block to drive the insertion rod to move towards the movable block. When the limiting plate moves to the limiting port, the insertion rod is inserted into the jack at one end of the movable block, so as to increase the length of the scraping block through the moving block. Then start the second motor to drive the rotating shaft and the rotating wheel to rotate. Through the transmission of the belt, drive the first transmission wheel, the second transmission wheel and the third transmission wheel to rotate, so that the fixed rod drives the scraping block to rotate to the water surface and come into direct contact with the scum. When the scraping 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 discharge pipe. Then the purified water is discharged through the sewage discharge pipe; Step 3: At the same time, when the scum is not scraped in time and too much scum accumulates on the liquid surface, start the first motor 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 out of the first installation groove. When the electric telescopic plate moves between the collecting block and the baffle, start the electric telescopic plate to extend, so that the first filter plate and the second filter plate are exposed. After the electric telescopic plate is fully extended, make the second magnetic block on one side of the electric telescopic plate magnetically connected to the first magnetic block on one side of the baffle to fix the positions of the first filter plate and the second filter plate. Thus, when too much scum accumulates on the liquid surface and sinks, it can fall on the first filter plate and the second filter plate for collection; Step 4: After the purified water is discharged, start the electric telescopic block on the left side of the absorption tube to contract, so that the electric telescopic block on the left drives the absorption tube through the third magnetic block and the fourth magnetic block to bend in the direction of contraction of the electric telescopic block on the left, so that the third magnetic block on the right side of the connecting plate is separated from the fourth magnetic block of the electric telescopic block on the right. When the electric telescopic block on the right 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, so that the electric telescopic tube moves left and right, so that the absorption tube absorbs the residual scum on the first filter plate and the second filter plate into the scum groove for collection. After the scum is cleaned, rotate the protective door. By contracting the first electric push rod, 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.
