Abstract
Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, and in particular to an integrated machine for washing and mixing highland barley with wastewater treatment function. Background Technology
[0002] Barley, a staple food crop in the Qinghai-Tibet Plateau region of my country, is rich in dietary fiber, glucan, and other nutrients, and is widely used in food processing, feed production, and other fields. In the deep processing of barley, washing and stirring are two core pretreatment steps. Washing removes impurities such as mud, dust, and straw fragments from the surface of the barley, while stirring ensures uniform mixing of the barley with water and additives, laying the foundation for subsequent grinding, cooking, and other processes. Currently, most barley washing and mixing equipment on the market adopts an integrated structure for washing and mixing. While this can improve processing efficiency to some extent, it has significant shortcomings in wastewater treatment, becoming a key bottleneck restricting the practicality and environmental friendliness of the equipment. The barley washing process generates a large amount of wastewater, which contains not only large particles of impurities such as mud, straw fragments, and barley husks detached from the barley surface, but also small amounts of small-molecule pollutants such as soluble starch and protein. Direct discharge of this wastewater would lead to a series of environmental and resource problems.
[0003] However, the few existing integrated machines equipped with simple filtration structures can only initially intercept large particulate impurities in the cleaning wastewater, resulting in poor filtration effects. They cannot achieve deep purification and reuse of wastewater. Furthermore, after long-term use, impurities tend to accumulate on the surface of the filter components, requiring regular manual disassembly and cleaning. This is not only cumbersome and time-consuming, but also affects the continuous operation efficiency of the equipment and increases maintenance costs.
[0004] In view of this, we have studied and improved the existing problems to provide an integrated barley washing and mixing machine with wastewater treatment function. The aim is to solve the problems and improve the practical value through this technology. Summary of the Invention

[0015] Preferably, a water spraying assembly is provided above the cleaning tank, and discharge ports are welded on both sides of the filter tank.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a scraper to gradually scrape barley debris and sand mixed in with the barley, intercepted on the surface of the filter plate, towards the discharge ports on both sides of the filter box, achieving centralized discharge of impurities. The filter plate effectively intercepts large particles of impurities in the washing wastewater, initially achieving coarse filtration of the wastewater and preventing large particles of impurities from entering subsequent mechanisms and causing blockages or damage. At the same time, no manual intervention is required to clean impurities, which not only reduces the labor intensity of operators and saves labor costs, but also effectively prevents impurities from accumulating on the surface of the filter plate and affecting filtration efficiency and effect.
[0017] 2. This invention achieves continuous automatic pressurization of wastewater through the reciprocating movement of the piston. The continuous pressurization enables the wastewater to pass through the ultrafiltration membrane at a faster speed, improving the efficiency of wastewater fine filtration. At the same time, the secondary filtration of the ultrafiltration membrane can further improve the quality of wastewater purification, ensuring that the discharged wastewater meets the cleanliness standards, enabling wastewater reuse and effectively saving water resources.
[0018] 3. This invention changes the travel of the moving plate driven by the threaded rod, and simultaneously changes the travel of the piston inside the pressurizing tube. This allows for automatic adjustment based on the accumulation of impurities inside the filter cartridge. By changing the piston's travel, it effectively prevents the piston from maintaining its original travel and generating excessive pressurizing thrust when the filtration resistance on one side of the ultrafiltration membrane increases due to impurity accumulation. This reduces the peak thrust of a single pressurization, preventing high pressure from directly impacting the surface of the ultrafiltration membrane with attached impurities. This effectively reduces the risk of damage or tearing of the ultrafiltration membrane, extends its service life, and lowers the later maintenance costs of the equipment. Attached Figure Description

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0022] See Figures 1 to 10As shown, the present invention provides a barley washing and mixing integrated machine with wastewater treatment function, including a washing tank 1, a washing mechanism inside the washing tank 1, a coarse filtration mechanism below the washing tank 1, the coarse filtration mechanism including a filter box 31 welded to the bottom of the washing tank 1, a filter plate 32 installed inside the filter box 31, a rotating shaft 37 rotatably provided inside the filter box 31, multiple sets of scrapers 38 fixed on the outer wall of the rotating shaft 37, and a drive mechanism for driving the rotating shaft 37 to rotate on the side wall of the filter box 31. It should be noted that, for reference Figures 1 to 3 As shown, after the barley is cleaned in the cleaning tank 1, the wastewater generated flows naturally into the filter box 31 connected to it below the cleaning tank 1. At this time, the first motor is started, which drives the lead screw 35 inside the guide rail 34 to rotate. The rotation of the lead screw 35 drives the slide 36 to reciprocate along the length of the guide rail 34. The slide 36 simultaneously drives the rotating shaft 37 to reciprocate. At the same time, the gear 39 fixed on the outer wall of the rotating shaft 37 meshes with the rack 310. When the rotating shaft 37 reciprocates with the slide 36, the gear 39 rotates along the axis of the rack 310, thereby driving the rotating shaft 37 to rotate synchronously. During the rotation of the rotating shaft 37, the scraper 38 moves together, so that the scraper 38 is solid on the upper surface of the filter plate 32. The scraping motion is a compound motion, with the scraper 38 made of elastic and wear-resistant rubber. The end of the scraper 38 is closely attached to the filter plate 32 and is evenly spaced in a ring. It moves in a compound motion with the rotating shaft 37, which can effectively scrape off large particles of impurities on the surface of the filter plate 32 and guide them to the discharge port 33, so that the impurities are automatically and centrally discharged, avoiding the clogging of the filter plate 32, eliminating the need for manual cleaning, and improving the continuity and stability of filtration. Through the compound motion trajectory design of the rotating shaft 37, the scraper 38 is both forceful and evenly covered, ensuring cleaning without dead corners and further guaranteeing the efficiency of waste residue treatment. At the same time, the filter plate 32 can effectively intercept large particles of impurities in the washing wastewater, initially achieving coarse filtration of the wastewater and preventing large particles of impurities from entering subsequent mechanisms and causing blockage or damage.
[0023] Below the coarse filtration mechanism is a pressurizing mechanism, which includes a water collection tank 41 installed below the filter box 31. Pressurizing pipes 42 are welded to both sides of the water collection tank 41. A piston 44 slides inside the pressurizing pipe 42. A through hole is opened on the surface of the piston 44. A limit rod 45 is fixed on one side of the piston 44. A sealing plate 46 is slidably sleeved on the outer wall of the limit rod 45. A spring A47 is provided between the limit rod 45 and the sealing plate 46. A cam 410 is sleeved on one end of the rotating shaft 37. A sliding plate 411 that is pressed and cooperates with the cam 410 slides on the side wall of the cleaning box 1. A threaded cylinder 412 is rotatably provided on one end of the sliding plate 411 through a bearing. A threaded rod 413 is threadedly connected inside the threaded cylinder 412. A moving plate 43 abuts against the top of the threaded rod 413. A connecting rod 48 is fixed on one end of the piston 44. A hinge rod 49 is hinged between the moving plate 43 and the connecting rod 48. It should be noted that, for reference Figures 4 to 8 As shown, when the wastewater passing through the filter plate 32 enters the water collection tank 41, the rotating shaft 37 will rotate continuously, causing the cam 410 to rotate as well. The rotating cam 410 will reciprocate to press the sliding plate 411, causing the sliding plate 411 to drive the threaded cylinder 412 and the threaded rod 413 to move up and down synchronously. When the sliding plate 411 drives the threaded cylinder 412 and the threaded rod 413 to move upward, the top of the threaded rod 413 will push the moving plate 43 to move upward synchronously. At this time, the moving plate 43 moves upward, driving the connecting rod 48 to move towards the inside of the water collection tank 41 through the hinge rod 49. The connecting rod 48 then drives the piston 44 to move synchronously. Since the piston 44 will be squeezed by the wastewater inside the water collection tank 41 when it moves, the sealing plate 46 will move away from the piston 44 along the outer wall of the limiting rod 45. At the same time, the spring A47 will be compressed. At this time, the wastewater inside the water collection tank 41 will enter the pressurization pipe 42 through the through hole on the surface of the piston 44 to complete the water storage. When the sliding plate 411 moves the threaded cylinder 412 and threaded rod 413 downwards, the moving plate 43 moves downwards synchronously under its own gravity. The moving plate 43, moving downwards, pushes the connecting rod 48 and piston 44 towards the inside of the pressurizing tube 42 through the hinge rod 49. The piston 44 then squeezes and pressurizes the wastewater stored inside the pressurizing tube 42. The pressurized wastewater flows into the fine filter box 51 through the water supply pipe 7. Under pressure, the pressurized wastewater entering the fine filter box 51 flows from the inside of the filter cylinder 54 to the outside. During the flow, it passes through the ultrafiltration membrane 57, which performs secondary fine filtration on the wastewater, removing residual fine impurities, colloids, and other pollutants. The filtered clean wastewater finally passes through the fine filter box 51. The wastewater is discharged through the drain pipe on the side, and through the through hole on the surface of the piston 44, in conjunction with the limit rod 45, the sealing plate 46 and the spring A47, the piston 44 switches between water storage and pressurization as it moves back and forth. When the piston 44 moves toward the water collection tank 41, the wastewater squeezes through the sealing plate 46 and enters the pressurization pipe 42 for water storage through the through hole. When the piston 44 moves toward the pressurization pipe 42, the sealing plate 46 resets and seals the through hole, squeezing and pressurizing the wastewater in the pipe, realizing continuous automatic pressurization of the wastewater. Through continuous pressurization, the wastewater can pass through the ultrafiltration membrane 57 at a faster speed to complete the filtration, improving the efficiency of wastewater fine filtration. At the same time, the secondary filtration of the ultrafiltration membrane 57 can further improve the quality of wastewater purification, ensuring that the discharged wastewater meets the cleanliness standard, enabling wastewater reuse and effectively saving water resources.
[0024] A fine filtration mechanism is located below the pressurization mechanism.
[0025] In an optional embodiment, the cleaning mechanism includes a cleaning cylinder 21 fixedly installed inside the cleaning tank 1. The cleaning cylinder 21 is rotatably equipped with a stirring shaft 22 driven by a second motor. Multiple sets of stirring rods 23 are sleeved on the outer wall of the stirring shaft 22. When cleaning the barley, the door on one side of the cleaning tank 1 is opened, and then the cylinder cover on one side of the cleaning cylinder 21 is opened. The barley to be cleaned is placed inside the cleaning cylinder 21. By starting the second motor and the water spray assembly, the second motor drives the stirring rods 23 to rotate through the stirring shaft 22 to clean and stir the barley.
[0026] In an optional embodiment, the drive mechanism includes a guide rail 34 welded to the side wall of the filter box 31. The guide rail 34 has a lead screw 35 driven by a first motor inside. The outer wall of the lead screw 35 is threadedly connected to a slide block 36. One end of a rotating shaft 37 is mounted on the side wall of the slide block 36 via a bearing. A gear 39 is sleeved on the outer wall of the rotating shaft 37. A rack 310 that meshes with the gear 39 is fixed on the inner wall of the guide rail 34.
[0027] In an optional embodiment, the scraper 38 is made of elastic and wear-resistant rubber material, and the end of the scraper 38 is in close contact with the upper surface of the filter plate 32. Each set of scrapers 38 is distributed in a ring at equal intervals on the outer wall of the rotating shaft 37. The scraper 38 made of elastic and wear-resistant rubber material can not only fit tightly with the filter plate 32 due to its elasticity, ensuring more thorough removal of barley debris, mud and other impurities attached to the surface of the filter plate 32, but also has wear-resistant properties, extending the service life of the scraper 38.
[0028] In an optional embodiment, a top rod 8 is fixed to the top of the sliding plate 411, and a brush plate 9 is fixed to the top of the top rod 8. One end of the spring A47 abuts against one side of the limiting rod 45, and the other end of the spring A47 abuts against one side of the sealing plate 46. When the sliding plate 411 moves up and down, the brush plate 9 moves up and down synchronously through the top rod 8. The brush plate 9 scrapes the filter holes of the filter plate 32 back and forth, which can help clean the small impurities that are blocked in the filter holes. Together with the scraper 38, it can further prevent the filter plate 32 from being blocked, and ensure that the wastewater can pass smoothly through the filter plate 32 into the water collection tank 41.
[0029] In an optional embodiment, the fine filtration mechanism includes a fine filter box 51 fixed below the water tank 41. A knob 52 is threaded to the bottom of the fine filter box 51. An air storage cylinder 53 is installed above the knob 52. A squeezing rod 55 slides inside the air storage cylinder 53. A filter cylinder 54 is fixed to the top of the squeezing rod 55. An ultrafiltration membrane 57 is installed inside the filter cylinder 54. The pressurization pipe 42 is connected to the fine filter box 51 through a water supply pipe 7. A one-way valve is provided at the connection between the water supply pipe 7 and the pressurization pipe 42. A control mechanism is provided above the fine filter box 51.
[0030] In an optional embodiment, the air storage cylinder 53 is provided with multiple sets of springs B56 inside, one end of each set of springs B56 abutting against the bottom end of the compression rod 55, and the other end of each set of springs B56 abutting against the inner wall of the air storage cylinder 53.
[0031] In an optional embodiment, the ultrafiltration membrane 57 is a hollow fiber ultrafiltration membrane, and the ultrafiltration membrane 57 is detachably installed inside the filter cartridge 54. The side wall of the filter cartridge 54 has several sets of evenly distributed water permeable holes. The hollow fiber ultrafiltration membrane 57 can improve the wastewater fine filtration effect and efficiently intercept fine impurities, colloids and other pollutants. The detachable installation design facilitates the later cleaning, replacement and maintenance of the ultrafiltration membrane 57, reducing the difficulty of equipment operation and maintenance. The evenly distributed water permeable holes on the side wall of the filter cartridge 54 can make pressurized wastewater flow evenly through the ultrafiltration membrane 57, ensuring fine filtration efficiency and effect.
[0032] In an optional embodiment, the control mechanism includes a sleeve 61 fixed below the sliding plate 411, a toothed ring 63 fixedly sleeved on the outer wall of the threaded cylinder 412, a rack rod 62 that meshes with the toothed ring 63 sliding inside the sleeve 61, a spring C65 inside the sleeve 61, one end of the spring C65 abutting against one end of the rack rod 62, and the other end of the spring C65 abutting against the inner wall of the sleeve 61, and a connecting pipe 64 connecting the air storage cylinder 53 and the sleeve 61.
[0033] It should be noted that, for reference Figures 8 to 10As the fine filtration operation continues, the impurities trapped inside the filter cartridge 54 will increase, leading to a continuous increase in the overall weight of the filter cartridge 54. This increased weight causes the filter cartridge 54 to compress the gas inside the gas storage cylinder 53 downwards via the bottom compression rod 55. The compressed gas is then transported to the sleeve 61 through the connecting pipe 64, gradually increasing the air pressure inside the sleeve 61. This increased pressure pushes the rack rod 62 inside the sleeve 61 to move along the inner wall of the sleeve 61. Since the rack rod 62 meshes with the toothed ring 63 fixed to the outer wall of the threaded cylinder 412, the movement of the rack rod 62 causes the toothed ring 63 to rotate. The toothed ring 63 then drives the threaded cylinder 412 to rotate synchronously. At this time, under the limiting action of the limiting post, the rotation of the threaded cylinder 412 is converted into the threaded rod 413 moving downwards inside the threaded cylinder 412, thereby changing the travel distance of the threaded rod 413 pushing the moving plate 43. Simultaneously, this changes the travel distance of the piston 44 inside the pressurization pipe 42. This allows the piston 44 to automatically adjust its movement based on the amount of impurities accumulated inside the filter cartridge 54. By adaptively changing the weight of the filter cartridge 54, the piston 44 can effectively avoid increasing the filtration resistance on one side of the ultrafiltration membrane 57 due to impurity accumulation. This prevents the piston 44 from maintaining its original stroke and generating excessive pressure, thus reducing the peak thrust of a single pressurization. This prevents high pressure from directly impacting the surface of the ultrafiltration membrane 57 with attached impurities, effectively reducing the risk of damage or tearing of the ultrafiltration membrane 57, extending its service life, and reducing the later maintenance costs of the equipment. In addition, during the initial compression filtration of the ultrafiltration membrane 57, when there is not much impurity accumulation inside the filter cartridge 54 and the filtration resistance on one side of the ultrafiltration membrane 57 is at a low level, the piston 44 will maintain its original normal stroke and generate corresponding pressure. This thrust is adapted to the tolerance of the ultrafiltration membrane 57 without significant impurity attachment and will not create a high-pressure impact beyond its tolerance range.
[0034] In an optional embodiment, a water spraying assembly is provided above the cleaning tank 1, and discharge ports 33 are welded to both sides of the filter tank 31.
[0035] Working principle: After the barley is cleaned in the cleaning tank 1, the wastewater will flow naturally into the filter box 31 connected to it below the cleaning tank 1. At this time, the first motor is started, which drives the lead screw 35 inside the guide rail 34 to rotate. The rotation of the lead screw 35 will drive the slide 36 to move back and forth along the length of the guide rail 34. The slide 36 will drive the rotating shaft 37 to move back and forth simultaneously. At the same time, when the rotating shaft 37 moves back and forth with the slide 36, the gear 39 will rotate along the axis of the rack 310, which will drive the rotating shaft 37 to rotate synchronously. During the rotation of the rotating shaft 37, the scraper 38 will move together, so that the scraper 38 can achieve a compound motion of scraping back and forth on the upper surface of the filter plate 32. Thus, the scraper 38 can gradually scrape the barley debris and mud mixed in the barley intercepted on the surface of the filter plate 32 towards the discharge port 33 on both sides of the filter box 31, so as to achieve the concentrated discharge of impurities. When the wastewater passing through the filter plate 32 enters the water collection tank 41, the rotating shaft 37 will rotate continuously, causing the cam 410 to rotate as well. The rotating cam 410 will reciprocate to press the sliding plate 411, causing the sliding plate 411 to drive the threaded cylinder 412 and the threaded rod 413 to move up and down synchronously. When the sliding plate 411 drives the threaded cylinder 412 and the threaded rod 413 to move upward, the top of the threaded rod 413 will push the moving plate 43 to move upward synchronously. At this time, the moving plate 43 moves upward, driving the connecting rod 48 to move towards the inside of the water collection tank 41 through the hinge rod 49. The connecting rod 48 then drives the piston 44 to move synchronously. As the piston 44 moves, it will be squeezed by the wastewater inside the water collection tank 41, causing the sealing plate 46 to move away from the piston 44 along the outer wall of the limiting rod 45. At the same time, the spring A47 is compressed by the force. At this time, the wastewater inside the water collection tank 41 will enter the pressurization pipe 42 through the through hole on the surface of the piston 44 to complete the water storage. When the sliding plate 411 drives the threaded cylinder 412 and the threaded rod 413 to move downward, the moving plate 43 moves downward synchronously under its own gravity. The moving plate 43 pushes the connecting rod 48 and the piston 44 to move towards the inside of the pressurizing tube 42 through the hinge rod 49. The piston 44 then squeezes and pressurizes the wastewater stored inside the pressurizing tube 42. The pressurized wastewater will flow into the fine filter box 51 through the water supply pipe 7. Under the action of pressure, the pressurized wastewater entering the inner cavity of the fine filter box 51 will flow from the inside of the filter cylinder 54 to the outside. During the flow, it will pass through the ultrafiltration membrane 57, and the wastewater will be finely filtered again through the ultrafiltration membrane 57. As the fine filtration operation continues, the impurities trapped inside the filter cartridge 54 will increase, thus increasing the overall weight of the filter cartridge 54. The increased weight of the filter cartridge 54 will cause the gas inside the gas storage cylinder 53 to be squeezed downwards by the extrusion rod 55 at the bottom. The squeezed gas is then transported to the sleeve 61 through the connecting pipe 64, causing the air pressure inside the sleeve 61 to gradually increase. The increased air pressure will push the rack rod 62 inside the sleeve 61 to move along the inner wall of the sleeve 61. The movement of the rack rod 62 will drive the gear ring 63 to rotate, which in turn will drive the threaded cylinder 412 to rotate synchronously. At this time, under the limiting action of the limiting post, the rotation of the threaded cylinder 412 will be converted into the downward movement of the threaded rod 413 inside the threaded cylinder 412, thereby changing the travel of the threaded rod 413 pushing the moving plate 43, and simultaneously changing the travel of the piston 44 inside the pressurization pipe 42.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
