Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically a device and method for the efficient treatment of high-concentration organic wastewater from the primary processing of edible agricultural products. Background Technology

[0002] my country is a major producer and processor of agricultural products, and the agricultural product processing industry is an important component of my country's agriculture. The annual discharge of wastewater from deep processing of agricultural products reaches billions of tons. This wastewater has a high concentration of organic matter and is rich in large-molecule proteins, small-molecule oligosaccharides, organic acids, and salts, making it more susceptible to biochemical treatment than other wastewater, but also extremely prone to spoilage. Properly treating wastewater from deep processing of agricultural products is a prerequisite for protecting the water environment and ensuring the sustainable development of the agricultural product processing industry.

[0003] Existing technologies typically use bar screens to filter wastewater after it is discharged into drainage tanks, and scrapers are used to clean the bar screens. However, as the scrapers move up and down, filtered wastewater always remains at the bottom of the scrapers, preventing the bar screens from achieving optimal filtration. Furthermore, larger particles like silt and sand settle at the bottom of the bar screens. This sedimentation not only reduces the filtration area of ​​the bar screens but also causes friction with the scrapers, damaging the cleaning equipment. Additionally, the wastewater filtered by the bar screens includes vegetable leaves, fruit peels, and colloids. After cleaning the bar screens with scrapers, this mixture adheres to the scrapers, and as the water continues to flow through the scrapers, these contaminants are re-introduced into the water, further affecting the bar screens' filtration efficiency. Moreover, the wastewater removed by the scrapers often contains residual wastewater. Direct discharge of this wastewater pollutes the surrounding environment and wastes water resources, making environmentally friendly treatment impossible.

[0004] Therefore, the present invention provides an efficient treatment device and method for high-concentration organic wastewater from the primary processing of edible agricultural products. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problems of persistent filtered waste at the bottom of the scraper as it moves up and down, preventing optimal filtration, and causing larger particles like silt to settle at the bottom, which reduces the filtration area and can damage the cleaning equipment, this invention proposes a highly efficient device and method for treating high-concentration organic wastewater from the initial processing of edible agricultural products. This addresses issues such as: the presence of filtered debris at the bottom of the scraper during primary processing, preventing optimal filtration; the accumulation of larger particles like silt and sand at the bottom of the scraper, which reduces the filtration area and can cause friction with the scraper; the presence of vegetable leaves, fruit peels, and colloids in the wastewater after scraping, which can be further mixed into the water as the scraper continues to move, thus affecting filtration efficiency; and the presence of residual wastewater within the scraper, which pollutes the environment and wastes water resources if discharged directly.

[0015] A method for efficiently treating high-concentration organic wastewater from primary processing of edible agricultural products, applicable to the aforementioned efficient treatment device for high-concentration organic wastewater from primary processing of edible agricultural products, comprising the following steps: S1: Wastewater circulates in the drainage pool, and a screen is used to filter out pollutants such as vegetable leaves, fruit peels, and colloids in the wastewater; S2: Start the first motor, control the reciprocating screw to rotate, drive the slide plate to move back and forth left and right, so that the scraper moves back and forth up and down against the screen to clean the screen; S3: With the cooperation of the linkage unit, the piston plate is controlled to move up and down repeatedly, forming two streams of water in the drainage pool, one up and one down, to clean up dirt such as vegetable leaves, fruit peels, and colloids under the scraper.

[0016] The beneficial effects of this invention are as follows: 1. The present invention provides an efficient treatment device and method for high-concentration organic wastewater from the primary processing of edible agricultural products. When the sliding plate approaches the pulley, the counterweight drives the scraper to move downward, scraping away the vegetable leaves, fruit peels, colloids, and other contaminants that remain on one side of the grid. By setting the scraper to be installed at an angle, the vegetable leaves, fruit peels, colloids, and other contaminants scraped downward by the scraper can flow along the inclined surface at the bottom of the scraper, avoiding accumulation at the bottom of the scraper.

[0017] 2. The present invention discloses an efficient treatment device and method for high-concentration organic wastewater from the primary processing of edible agricultural products. A piston plate is controlled by a linkage unit to reciprocate up and down. When the piston plate moves downwards, it squeezes the wastewater in the casing along the pipe into the inlet tank. The wastewater entering the inlet tank is discharged along two outlet tanks. Guided by the inclined surfaces inside the two outlet tanks, two streams of water flow, one upward and one downward, are formed in the drainage pool. The upward-spraying water impacts the area below the scraper, and with the guidance of the inclined surface at the bottom of the scraper, effectively prevents vegetable leaves, fruit peels, colloids, and other contaminants from accumulating below the scraper and causing grid blockage. The downward-spraying water washes up the sediment at the bottom of the drainage pool, preventing larger sediments from settling at the bottom of the grid, affecting the filtration area of ​​the grid, and preventing sediment from colliding with the scraper and damaging the cleaning equipment.

[0018] 3. The present invention provides an efficient treatment device and method for high-concentration organic wastewater from the primary processing of edible agricultural products. By controlling the rotation of a second shaft with a second motor, several blades rotate. When the scraper moves to the through groove, the large pieces of dirt on the scraper are dislodged by the rotation of the blades, thus accelerating the sludge removal process.

[0019] 4. The present invention provides an efficient treatment device and method for high-concentration organic wastewater from the primary processing of edible agricultural products. By controlling the rotation of the second rotating shaft to drive the rotation of several top rods, the scraper can be intermittently vibrated upwards under the cooperation of the top rods and the top block. This prevents vegetable leaves, fruit peels, colloids and other contaminants from sticking to the scraper and being unable to be discharged. This also prevents the sticky vegetable leaves, fruit peels, colloids and other contaminants from being mixed back into the wastewater after the scraper is re-entered into the wastewater.

[0020] 5. The present invention provides an efficient treatment device and method for high-concentration organic wastewater from the primary processing of edible agricultural products. The wastewater carried in the sludge can be drained through the sieve in the hopper. The drained wastewater is guided along the inclined surface at the bottom of the guide plate and re-enters the drainage pool from the inlet, thereby avoiding the pollution of the surrounding environment by the wastewater and preventing environmental treatment.

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 11 As shown, the present invention provides a technical solution: a high-efficiency treatment device for high-concentration organic wastewater from the primary processing of edible agricultural products, comprising a drainage tank 1, a grid 2 fixedly connected to the inner wall of the drainage tank 1, a top plate 3 fixedly connected to the outer wall of the grid 2, the top plate 3 fixedly connected to the drainage tank 1, two first sliding shafts 4 symmetrically fixedly connected to the bottom of the top plate 3, the bottoms of the two first sliding shafts 4 being fixedly connected to the drainage tank 1, a first slider 5 slidably connected to the outer walls of the two first sliding shafts 4, a counterweight 6 fixedly connected to the bottom of the first slider 5, and a counterweight 6 symmetrically fixedly connected to one side of the first slider 5. There are two mounting plates 7, and mounting blocks 11 are slidably connected to one side of each mounting plate 7. A second sliding shaft 9 is fixedly connected to the inner wall of the mounting block 11, and a second slider 8 is slidably connected to the outer wall of the second sliding shaft 9. The second slider 8 is fixedly connected to the mounting plate 7. A spring 10 is sleeved on the outer wall of the second sliding shaft 9. The top of the spring 10 is fixedly connected to the mounting block 11, and the bottom of the spring 10 is fixedly connected to the second slider 8. A scraper 12 is fixedly connected to one side of both mounting blocks 11. The scraper 12 is installed at an angle and fits against the outer wall of the grid 2. A slag removal device is provided on the top of the top plate 3. The slag removal assembly includes a bracket 13, which is fixedly installed on the top of the top plate 3. A pulley 14 is rotatably connected to the inner wall of the bracket 13. A through groove 22 is opened inside the grille 2. A side plate 17 is fixedly connected to the inner wall of the drainage pool 1 on the side away from the grille 2. A limiting shaft 15 is fixedly connected between the side plate 17 and the grille 2. A connecting block 16 is slidably connected to the outer wall of the limiting shaft 15. A sliding plate 20 is fixedly connected to the top of the connecting block 16. The sliding plate 20 is slidably connected to the drainage pool 1. A first motor 18 is fixedly connected to one side of the side plate 17. The first motor 18 outputs... The outlet passes through the side plate 17 and is fixedly connected to a reciprocating screw 19. The reciprocating screw 19 is rotatably connected to the grid 2. The reciprocating screw 19 is connected to the connecting block 16 through a screw nut pair. Two pull ropes 21 are symmetrically fixedly connected to one side of the slide plate 20. The ends of the two pull ropes 21 pass around the pulley 14 and are fixedly connected to the first slider 5. Both sides of the drainage pool 1 are provided with sewage outlets 24. A guide plate 23 is fixedly connected to the inner wall of the drainage pool 1 and below the sewage outlets 24. The top of the guide plate 23 is set as a symmetrical slope. One side of the guide plate 23 is fixedly connected to the grid 2.

[0026] Through the above technical solution, wastewater flows in drainage pool 1. The wastewater is filtered by a screen 2 to remove contaminants such as vegetable leaves, fruit peels, and colloids, trapping these contaminants on one side of the screen 2. The filtered wastewater continues to flow along drainage pool 1 for further purification. The first motor 18 is started, driving the connecting block 16 to move back and forth, causing the sliding plate 20 to move back and forth. When the sliding plate 20 moves away from the pulley 14, the pull rope 21 pulls the first slider 5 and counterweight 6 upwards, causing the mounting plate 7 and second slider 8 to move upwards. Supported by the spring 10, the mounting block 11 moves upwards, causing the scraper 12 to move upwards. During this upward movement, the scraper 12 removes the contaminants such as vegetable leaves, fruit peels, and colloids trapped on one side of the screen 2, moving them upwards until they reach the passage trough 22. At this time, vegetable leaves, fruit peels, colloids, and other waste fall down the inclined surface at the top of the scraper 12, pass through the channel 22, and land on the guide plate 23. Guided by the inclined surface at the top of the guide plate 23, the vegetable leaves, fruit peels, colloids, and other waste are discharged into the drainage pool 1 through the drain outlet 24. When the slide plate 20 moves towards the side closer to the pulley 14, under the action of the counterweight 6, the first slider 5 and the scraper 12 move downward. During the downward movement of the scraper 12, the waste remaining on one side of the grid 2 is again cleaned. The scraper removes dirt such as vegetable leaves, fruit peels, and colloids. By setting the scraper 12 to be installed at an angle, the dirt such as vegetable leaves, fruit peels, and colloids scraped down by the scraper 12 can be dispersed along the inclined surface at the bottom of the scraper 12, avoiding accumulation at the bottom of the scraper 12. This process is repeated. With the start of the first motor 18, the scraper 12 can continuously clean the screen 2, and prevent the accumulation of dirt such as vegetable leaves, fruit peels, and colloids below the scraper 12, which would affect the water filtration effect of the screen 2.

[0027] Specifically, a pipe 25 is fixedly connected to the inner wall of the grille 2 and below the scraper 12. A fixing plate 26 is fixedly connected to the outer wall of the pipe 25. A water inlet groove 27 is opened inside the fixing plate 26. The end of the pipe 25 extends into the interior of the water inlet groove 27. Two water outlet grooves 28 are symmetrically opened on the outer wall of the fixing plate 26. One water outlet groove 28 is opened upward and the other is opened downward. Both water outlet grooves 28 are connected to the water inlet groove 27. A water spraying assembly is provided at the top of the pipe 25. The water spraying assembly includes a sleeve 29, which is fixedly connected to the top of the pipe 25. Two one-way valves 32 are symmetrically fixedly connected to the inner wall of the pipe 25 with the sleeve 29 as the center. Both one-way valves 32 are open towards the fixing plate 26. A piston plate 30 is slidably connected to the inner wall of the sleeve 29. A piston rod 31 is fixedly connected to the top of the piston plate 30. The top of the piston rod 31 passes through the sleeve 29 and is rotatably connected to a connecting shaft 36. A linkage unit is provided inside the drainage pool 1.

[0028] Through the above technical solution, when the first motor 18 starts, it drives the piston rod 31 to move up and down reciprocally through the linkage unit, causing the piston plate 30 to move up and down reciprocally. When the piston plate 30 moves upward, the pulling action of the piston plate 30, in conjunction with the two one-way valves 32, allows the wastewater filtered of vegetable leaves, fruit peels, colloids, and other impurities to be drawn along the pipe 25 into the casing 29. When the piston plate 30 moves downward, the squeezing action of the piston plate 30 forces the wastewater in the casing 29 along the pipe 25 into the inlet tank 27. The wastewater entering the inlet tank 27 is then discharged along the two outlet tanks 28. The inclined surfaces inside the two water outlets 28 guide the flow of water, creating two streams of water, one above and one below, within the drainage tank 1. The upward-spraying water impacts the area below the scraper 12, and combined with the guiding effect of the inclined surface at the bottom of the scraper 12, effectively prevents dirt such as vegetable leaves, fruit peels, and colloids from accumulating below the scraper 12 and clogging the screen 2. The downward-spraying water washes up the sediment at the bottom of the drainage tank 1, preventing larger sediments from settling at the bottom of the screen 2, affecting the filtration area of ​​the screen 2, and preventing the settled sediment from colliding with the scraper 12 and damaging the cleaning equipment.

[0029] Specifically, the linkage unit includes a positioning plate 33, which is fixedly installed inside the drainage pool 1 and located below the guide plate 23. The inner wall of the positioning plate 33 is rotatably connected to a first rotating shaft 34. One end of the first rotating shaft 34 is fixedly connected to a crank 35, which is rotatably connected to a connecting shaft 36. The other end of the first rotating shaft 34 is fixedly connected to a second synchronous pulley 38. The outer wall of the reciprocating screw 19 is fixedly connected to a first synchronous pulley 37, and the first synchronous pulley 37 and the second synchronous pulley 38 are connected by a synchronous belt 39.

[0030] Through the above technical solution, the reciprocating screw 19 rotates while driving the first synchronous pulley 37 to rotate. Through the transmission of the synchronous belt 39, the second synchronous pulley 38 rotates, driving the first rotating shaft 34 to rotate, causing the crank 35 to rotate. When the protruding end of the crank 35 rotates to the top, it drives the connecting shaft 36 to move upward, causing the piston rod 31 to move upward. When the protruding end of the crank 35 rotates to the bottom, it pushes the connecting shaft 36 to move downward, causing the piston rod 31 to move downward. This process repeats, and as the reciprocating screw 19 rotates, it drives the piston rod 31 to move up and down reciprocally.

[0031] Specifically, a second motor 40 is fixedly connected to the outer wall of the drainage pool 1. The output end of the second motor 40 extends into the interior of the drainage pool 1 and is fixedly connected to a second rotating shaft 41. The second rotating shaft 41 is located above the through groove 22. Several blades 42 are fixedly connected to the outer wall of the second rotating shaft 41 in a ring array. The blades 42 are set in an arc shape.

[0032] By using the above technical solution, the second motor 40 is started, which drives the second rotating shaft 41 to rotate, causing several blades 42 to rotate. When the scraper 12 moves to the through groove 22, the large pieces of dirt on the scraper 12 can be scraped off as the blades 42 rotate, thus speeding up the cleaning process.

[0033] Specifically, two top blocks 44 are symmetrically fixedly connected to the top of the scraper 12. The top of the top block 44 is set as an inclined surface. Two sets of vibration units are symmetrically arranged on the outer wall of the second rotating shaft 41. The vibration unit includes several top rods 43. The several top rods 43 are fixedly installed on the outer wall of the second rotating shaft 41 in a ring array. The top rods 43 and the top blocks 44 cooperate with each other.

[0034] Through the above technical solution, the second rotating shaft 41 rotates while driving several top rods 43 to rotate. When the top rod 43 rotates to the top block 44, it pushes the top block 44 to move downward, causing the scraper 12 to move downward, driving the mounting block 11 to move downward, and pressing the spring 10. When the top rod 43 rotates to the position where it is disengaged from the top block 44, it loses the pressure of the top rod 43. Under the action of the spring 10, it drives the mounting block 11 and the scraper 12 to move upward and vibrate. This process is repeated. With the continuous rotation of several top rods 43, the scraper 12 can vibrate upward intermittently, preventing vegetable leaves, fruit peels, colloids and other dirt from sticking to the scraper 12 and being unable to be discharged. After the scraper 12 re-enters the water, the sticky vegetable leaves, fruit peels, colloids and other dirt will be mixed into the wastewater again.

[0035] Specifically, a support frame 45 is fixedly connected to both sides of the drainage pool 1. A hopper 47 is placed on the top of the support frame 45. A screen is opened at the bottom of the hopper 47. The hopper 47 is located below the sewage outlet 24. A guide plate 46 is fixedly connected to the bottom of the support frame 45. The bottom of the guide plate 46 is set as an inclined surface. Water inlets 48 are opened on both sides of the drainage pool 1 and above the guide plate 46.

[0036] Through the above technical solution, the sewage discharged from the sewage outlet 24 falls into the hopper 47 for drainage. The wastewater carried in the sewage is drained through the sieve. The drained wastewater is guided by the bottom slope of the guide plate 46 and enters the drainage pool 1 again from the inlet 48. This avoids the wastewater from polluting the surrounding environment and preventing environmental protection treatment.

[0037] A method for efficiently treating high-concentration organic wastewater from primary processing of edible agricultural products, applicable to the aforementioned efficient treatment device for high-concentration organic wastewater from primary processing of edible agricultural products, comprising the following steps: S1: Wastewater flows in drainage pool 1, and screen 2 is used to filter out pollutants such as vegetable leaves, fruit peels, and colloids in the wastewater; S2: Start the first motor 18, control the reciprocating screw 19 to rotate, drive the slide plate 20 to move back and forth left and right, so that the scraper 12 moves back and forth up and down against the grid 2 to clean the slag; S3: With the cooperation of the linkage unit, the piston plate 30 is controlled to move up and down repeatedly, forming two streams of water in the drainage pool 1, one up and one down, to clean up the vegetable leaves, fruit peels, colloids and other dirt below the scraper 12.

[0038] In operation, wastewater flows through drainage pool 1, filtering out impurities such as vegetable leaves, fruit peels, and colloids from the wastewater through screen 2. These impurities are trapped on one side of screen 2. The filtered wastewater continues to flow through drainage pool 1 for further purification. The first motor 18 is started, controlling the reciprocating screw 19 to rotate, causing the connecting block 16 to move back and forth, thus moving the sliding plate 20 back and forth. When the sliding plate 20 moves away from the pulley 14, the pull rope 21 pulls the first slider 5 and counterweight 6 upwards, causing the mounting plate 7 and mounting block 11 to move upwards, and the scraper 12 to move upwards. During the upward movement of the scraper 12, the vegetable leaves, fruit peels, and colloids trapped on one side of screen 2 are removed. The scraper removes dirt and debris, causing vegetable leaves, fruit peels, and colloids to move upwards. When the scraper 12 reaches the channel 22, the dirt and debris fall down the inclined surface at the top of the scraper 12, pass through the channel 22, and land on the guide plate 23. Guided by the inclined surface at the top of the guide plate 23, the dirt and debris are discharged into the drainage pool 1 through the drain outlet 24. The dirt discharged from the drain outlet 24 falls into the hopper 47 for drainage. The wastewater carried in the dirt is drained through the sieve. The drained wastewater is guided by the inclined surface at the bottom of the guide plate 46 and re-enters the drainage pool 1 through the inlet 48. This avoids wastewater pollution of the surrounding environment and prevents environmental treatment. When the slide plate 20 moves towards the pulley 14, the counterweight 6 acts as a guide. The first slider 5 and scraper 12 move downwards. During the downward movement of scraper 12, the vegetable leaves, fruit peels, colloids, and other debris remaining on one side of the grid 2 are scraped off again. By setting scraper 12 to be installed at an angle, the vegetable leaves, fruit peels, colloids, and other debris scraped off by scraper 12 can flow along the inclined surface at the bottom of scraper 12, avoiding accumulation at the bottom of scraper 12. This process is repeated. With the start of the first motor 18, scraper 12 can continuously clean the grid 2, and prevent the accumulation of vegetable leaves, fruit peels, colloids, and other debris below scraper 12, which would affect the water filtration effect of grid 2. The reciprocating screw 19 rotates while driving the first synchronous pulley 37 to rotate. Through the transmission of synchronous belt 39, the second synchronous pulley 38 rotates, driving the first rotating shaft 34. Rotation causes crank 35 to rotate. When the protruding end of crank 35 rotates to the upper position, it drives the connecting shaft 36 to move upward, causing the piston rod 31 to move upward. When the protruding end of crank 35 rotates to the lower position, it pushes the connecting shaft 36 to move downward, causing the piston rod 31 to move downward. This process repeats. As the reciprocating screw 19 rotates, it drives the piston rod 31 to move up and down repeatedly, causing the piston plate 30 to move up and down repeatedly. When the piston plate 30 moves upward, the pulling action of the piston plate 30, in conjunction with the two one-way valves 32, allows wastewater filtered of vegetable leaves, fruit peels, colloids, and other impurities to be drawn along the pipe 25 into the casing 29. When the piston plate 30 moves downward, the squeezing action of the piston plate 30 forces the wastewater in the casing 29 along the pipe 25 into the inlet tank 27.Wastewater entering the inlet tank 27 is discharged along the two outlet tanks 28. Guided by the inclined surfaces inside the two outlet tanks 28, two streams of water flow, one above and one below, are formed in the drainage tank 1. The upward spray of water impacts the area below the scraper 12. Combined with the guidance of the inclined surface at the bottom of the scraper 12, this effectively prevents vegetable leaves, fruit peels, colloids, and other debris from accumulating below the scraper 12 and clogging the screen 2. The downward spray of water washes up the silt deposited at the bottom of the drainage tank 1, preventing larger silt from settling at the bottom of the screen 2, affecting the filtration area of ​​the screen 2, and preventing the settled silt from colliding with the scraper 12 and damaging the cleaning equipment. The second motor 40 is started, driving the second rotating shaft 41 to rotate, causing several blades 42 to rotate. When the scraper 12 moves to the through channel 22, as... The rotation of blade 42 dislodges large pieces of debris from scraper 12, accelerating the cleaning process. Simultaneously, the rotation of the second shaft 41 drives several push rods 43. When a push rod 43 rotates to the top block 44, it pushes the top block 44 downwards, causing scraper 12 to move downwards and the mounting block 11 to move downwards, compressing the spring 10. When a push rod 43 rotates to a position where it disengages from the top block 44, it loses its pressure. Under the action of the spring 10, the mounting block 11 and scraper 12 move upwards and vibrate. This process repeats, and with the continuous rotation of the push rods 43, scraper 12 intermittently vibrates upwards, preventing vegetable leaves, fruit peels, colloids, and other debris from sticking to scraper 12 and preventing them from being re-entered into the wastewater.
