Description

Technical Field

[0001] The invention relates to the technical field of waste water treatment, in particular to a waste water treatment device for washing in a production process of agricultural products. Background Art

[0002] Agricultural products refer to primary products derived from planting, forestry, animal husbandry and fishery, that is, plants, animals, microorganisms and their products obtained in agricultural activities, such as rice, sorghum, peanuts, corn, wheat and local specialties of various regions. Fruits and vegetables also fall into the category of agricultural products.

[0003] At present, before fruits and vegetables are transported to the market for sale, they need to be cleaned after picking. The pesticide residues, mosquitoes and mud on the outer surface of fruits and vegetables are washed away by cleaning. The wastewater after cleaning cannot be directly recycled due to impurities such as mud and pesticide residues. Therefore, for environmental protection and waste recycling, the wastewater after cleaning needs to be treated so that the treated wastewater can be reused or meet the discharge requirements. In the prior art, the treatment of wastewater is generally to filter the impurities and mud through the filter element after cleaning, and then degrade the filtered sewage again by chemical treatment. However, during the filtering process, the filter element will gradually be filled with impurities such as mud and sand, resulting in a poor filtering effect of the filter element. At this time, the filter element needs to be replaced, but since there is generally only one set of filter elements in the treatment equipment, it is necessary to stop the transportation of sewage when replacing it, thereby affecting the efficiency of sewage treatment.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention proposes a waste water treatment device for cleaning in the process of agricultural product production. When treating the waste water after cleaning, the connecting pipe is connected to the cleaning equipment. At this time, the waste water enters the connecting pipe through the connecting pipe, and the connecting pipe is provided with a control member for controlling the opening and closing of multiple groups of water delivery pipes. The waste water can pass through multiple groups of different filter tanks in sequence through the action of the control member. Therefore, after the filtering effect of the filter element becomes poor, the control member controls the waste water to enter another group of filter tanks for filtering. Therefore, in the process of waste water filtering, the waste water filtering can be uninterrupted through the action of the control member, and the mobile component will be triggered to start during the waste water transportation process. The action of the reciprocating screw rod causes the rotation of the reciprocating screw rod, thereby causing the filter element to gradually rise through the rotation of the reciprocating screw rod. After the filter element rises to the top of the filter tank, the filtering performance of the filter element is relatively low at this time. By moving the sealing top cover, the filter element is exposed to the outside, thereby facilitating the cleaning of the filter element after filtering the wastewater, so that it can continue to filter the wastewater. Therefore, through the mutual cooperation of the water inlet assembly and the moving assembly, the wastewater filtration will not be interrupted, and it is convenient to clean the filter element after filtration, ensuring that each group of filter elements can continue to filter the wastewater, thereby solving the problem in the prior art that the filter element needs to be cleaned during the wastewater filtration process, resulting in interruption of wastewater filtration and affecting the wastewater treatment efficiency.

[0017] 2. The present invention proposes a waste water treatment device for cleaning in the process of agricultural product production. A reciprocating screw is arranged to be threadedly connected with the filter element. Therefore, when the filter element is installed, the filter element is first located at the top of the filter tank. Under the rotation of the reciprocating screw, the filter element first moves down to the bottom of the filter tank and then rises to the top of the filter tank. In this scheme, after the filter element has been lowered and raised once, the filtering performance of the filter element will become very low, and the filter element needs to be cleaned. The reciprocating movement of the filter element can facilitate the judgment of when the filter element needs to be cleaned, so that the filter element can be cleaned in time to avoid the deterioration of the sewage treatment effect due to the reduction of the performance of the filter element.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-9The present invention provides a technical solution: a waste water treatment device for washing in the process of agricultural product production, comprising a drainage box 1, a moving component 7 and a water inlet component 10, the drainage box 1 is connected with a drainage pipe 2, and the top of the drainage box 1 is connected with a plurality of water outlet pipes 3, the top of the water outlet pipe 3 is connected with a filter tank 4, the top of the filter tank 4 is installed with a sealing top cover 5, and the filter tank 4 is installed with a filter element 6, the moving component 7 comprises a reciprocating screw 8 threadedly connected to the filter element 6, the reciprocating screw 8 is rotatably connected to the filter tank 4, and is located at an eccentric position of the filter tank 4, and the top of the reciprocating screw 8 is fixedly connected with a connecting column 9 The movable assembly 7 drives the filter element 6 to move from the bottom position of the filter tank 4 to the top position of the filter tank 4 through the rotation of the reciprocating screw 8. The water inlet assembly 10 includes a water inlet pipe 11 connected to multiple groups of the sealing top covers 5. The top of the water inlet pipe 11 is connected to a cover body 12, and a sealing ring 13 is rotatably connected to the cover body 12. The water inlet assembly 10 transports sewage to the inside of the filter tank 4 through the action of the water inlet pipe 11 to filter the sewage through the filter element 6, and the water inlet assembly 10 is used to transport sewage to multiple groups of the filter tanks 4 in turn, and the water inlet assembly 10 cooperates with the movable assembly 7 to move the filter element 6.

[0030] In this solution, when treating sewage, the sealing top cover 5 is opened, and the multiple groups of filter elements 6 are all installed on the top of the multiple groups of filter tanks 4, and the filter elements 6 at this time are inserted on the connecting column 9. At this time, the water inlet component 10 is connected to the cleaning equipment, and the sewage is transported to one of the multiple groups of cover bodies 12 through the action of the water inlet component 10. At this time, the sewage will enter the filter tank 4 through the water inlet pipe 11, and the filter tank 4 is provided with a filter element 6. The wastewater is filtered by the action of the filter element 6. In this process, the reciprocating screw 8 is rotated by the action of the moving component 7, and the filter element 6 is first lowered and then raised by the rotation of the reciprocating screw 8. After one round trip, the wastewater is transported to another group of cover bodies 12 through the action of the water inlet component 10. At this time, the wastewater will enter another group of filter tanks 4 for filtration, and the filter element 6 after filtering the wastewater in the previous group can be cleaned at this time, which is convenient for the subsequent treatment of the wastewater.

[0031] The sealing top cover 5 includes a movable tube 14 plugged into the filter tank 4, the outer side of the movable tube 14 is fixedly connected to a fixing ring 15, a clamping member 17 is installed between the fixing ring 15 and the filter tank 4, and the outer side of the movable tube 14 is slidably connected to a sealing cover 16, a fixing frame 18 is fixedly connected between multiple groups of the sealing covers 16, and a support rod 19 fixedly connected to the fixing frame 18 is fixedly connected to the drainage box 1. The clamping member 17 includes a rotating disk 47 sleeved on the outside of the filter tank 4, and the top of the rotating disk 47 is fixedly connected to multiple groups of fixed columns 48 that are slidably connected to the filter tank 4 and the fixed ring 15. The fixed columns 48 are fixedly connected to the limiting blocks 50, and the filter tank 4 and the fixed ring 15 are respectively provided with a first sliding groove 49 and a second sliding groove 51 that are adapted to the fixed columns 48. The end of the second sliding groove 51 is provided with a through hole 52 with a diameter larger than the limiting block 50. The outer side of the rotating disk 47 is provided with an anti-slip protrusion, and the fixed ring 15 is fixedly connected with a connecting ring 53.

[0032] In this solution, when installing the filter element 6, by rotating the rotating disk 47, the rotating disk 47 drives the fixed column 48 to slide inside the first sliding groove 49 and the second sliding groove 51. When the fixed column 48 slides to the end of the first sliding groove 49 and the second sliding groove 51, since the diameter of the through hole 52 is greater than the diameter of the limit block 50, the limit block 50 cannot limit the fixing ring 15 at this time, and then the fixing ring 15 is slid upward, and the movable tube 14 is driven to move upward through the action of the fixing ring 15, so that the movable tube 14 is separated from the filter tank 4. At this time, the filter element 6 is installed on the connecting column 9, and then the movable tube 14 is pulled down, and the rotating disk 47 is rotated in the opposite direction, so that the fixed column 48 slides to the other end of the first sliding groove 49 and the second sliding groove 51. At this time, the limit block 50 limits the fixing ring 15, so that the movable tube 14 is stably connected to the filter tank 4.

[0033] When the filter element 6 is cleaned, the rotating disk 47 is rotated to drive the fixing post 48 to slide inside the first sliding groove 49 and the second sliding groove 51. When the fixing post 48 slides to the end of the first sliding groove 49 and the second sliding groove 51, the diameter of the through hole 52 is larger than the diameter of the limit block 50. At this time, the limit block 50 cannot limit the fixing ring 15, and then the fixing ring 15 is slid upward, and the movable tube 14 is driven to move upward by the action of the fixing ring 15, so that the movable tube 14 is separated from the filter tank 4. At this time, the filter element 6 is located on the connecting column 9 and is separated from the reciprocating screw rod 8. Then, the filter element 6 is directly taken out to rinse and clean the filter element 6. After cleaning, the filter element 6 is installed on the connecting column 9, and then the movable tube 14 is pulled down, and the rotating disk 47 is rotated in the opposite direction to make the fixing post 48 slide to the other end of the first sliding groove 49 and the second sliding groove 51. At this time, the limit block 50 limits the fixing ring 15, so that the movable tube 14 is stably connected to the filter tank 4 again.

[0034] The moving assembly 7 includes an insertion rod 20 plugged into the connecting column 9, a slot 21 adapted to the insertion rod 20 is provided on the connecting column 9, and a rotating column 22 is fixedly connected to the top end of the insertion rod 20, the outer side surface of the rotating column 22 is rotatably connected to a fixing seat 23 fixedly connected to the movable tube 14, and the top end of the rotating column 22 is fixedly connected to a prismatic column 24, the outer side surface of the prismatic column 24 is slidably connected to a rotating shaft 25 rotatably connected to the sealing cover 16, and a rotating member 26 for driving the rotating shaft 25 to rotate is installed at the top end of the rotating shaft 25, and the rotating member 26 is arranged in cooperation with the water inlet assembly 10. The rotating member 26 includes blades 27 fixedly connected to the sealing ring 13. The blades 27 are provided in multiple groups and are arranged circumferentially on the outer surface of the sealing ring 13. The inner wall of the sealing ring 13 is fixedly connected to a rotating plate 28. The axis of the rotating plate 28 is fixedly connected to a connecting shaft 29. The shaft end of the connecting shaft 29 is fixedly connected to a first spur gear 30. The outer side of the first spur gear 30 is meshed with a second spur gear 31 fixedly connected to the rotating shaft 25.

[0035] In this solution, after the wastewater enters the cover body 12, the wastewater will impact the blade 27 so that the blade 27 rotates along the axis of the cover body 12, and then the sealing ring 13 is driven to rotate by the rotation of the blade 27. The rotation of the sealing tube will drive the rotating plate 28 to rotate, and the rotation of the rotating plate 28 drives the connecting shaft 29 to rotate, and then drives the first flat gear 30 to rotate, and the second flat gear 31 is driven to rotate by the action of the first flat gear 30, and then drives the rotating shaft 25 fixedly connected thereto to rotate, and the prismatic column 24 slidably connected thereto is driven to rotate by the action of the rotating shaft 25, and the rotating column 29 is driven to rotate by the rotation of the prismatic column 24. 22 rotates, thereby driving the insertion rod 20 to rotate, and the action of the insertion rod 20 drives the connecting column 9 to rotate, thereby driving the reciprocating screw 8 to rotate. Since the water will fall on the filter element 6 after entering the filter tank 4, the filter element 6 is tightly connected to the reciprocating screw 8 through the gravity of the water. Therefore, the rotation of the reciprocating screw 8 will drive the filter element 6 to move downward. After moving downward to the bottom end of the reciprocating screw 8, the filter element 6 will move in the opposite direction and rise under the continuous rotation of the reciprocating screw 8, and then the rotation of the reciprocating screw 8 makes the filter element 6 reciprocate. After the filter element 6 rises to the top of the reciprocating screw 8, the filter element 6 needs to be cleaned.

[0036] In this solution, the diameter of the first spur gear 30 is smaller than the diameter of the second spur gear 31. Therefore, when the first spur gear 30 rotates, the second spur gear 31 will rotate more slowly, thereby making the reciprocating screw 8 rotate more slowly, thereby making the filter element 6 move more slowly, ensuring that the filter element 6 can filter the wastewater to the maximum extent.

[0037] The water inlet assembly 10 includes a connecting pipe 32 connected to the cleaning device, the end of the connecting pipe 32 is connected to a connecting pipe 33, the connecting pipe 33 is connected to multiple groups of water pipes 35, the end of the water pipe 35 is connected to a butt joint 36, the multiple groups of butt joint 36 are respectively connected to multiple groups of the cover body 12, and a control member 34 for controlling the opening and closing of the multiple groups of water pipes 35 is installed inside the connecting pipe 33. The control member 34 includes a shaft sleeve 37 fixedly connected to the connecting pipe 33, a motor 38 is fixedly connected to the shaft sleeve 37, and a driving shaft 39 rotatably connected to the connecting pipe 33 is fixedly connected to the output end of the motor 38, the driving shaft 39 extends into the inside of the connecting pipe 33 and is fixedly connected to a sealing block 40, a notch 42 is opened on the sealing block 40, and a limiting member 41 is installed between the sealing block 40 and the connecting pipe 33. The limiting member 41 includes a spring 43 fixed in the sealing block 40, the top end of the spring 43 is fixedly connected to a sliding column 44 slidably connected to the sealing block 40, the top end of the sliding column 44 is rotatably connected to a ball 45 movably connected to the connecting tube 33, and a ball groove 46 adapted to the ball 45 is opened on the inner wall of the connecting tube 33.

[0038] In this solution, when treating wastewater, the connecting pipe 32 is connected to the cleaning equipment, and the cleaned wastewater will enter the connecting pipe 33 through the connecting pipe 32. After the wastewater enters the connecting pipe 33, the wastewater will enter the water pipe 35 corresponding to the notch 42 through the notch 42, and then enter the docking pipe 36 through the delivery pipe. Then, the wastewater is transported to the filter tank 4 for filtering through the cover body 12 and the water inlet pipe 11. After the filter element 6 in the filter tank 4 moves back and forth, the filtering performance of the filter element 6 is very low and needs to be cleaned. At this time, the motor 38 is started, and the driving shaft 39 is driven to rotate by the action of the motor 38, and the sealing block 40 is driven to rotate by the rotation of the driving shaft 39, so that the notch 42 rotates to correspond to another set of water pipes 35. At this time, the wastewater will enter the other set of filter tanks 4 through the notch 42 for filtration.

[0039] In this solution, during the rotation of the sealing block 40, the ball 45 will squeeze the spring 43 through the sliding column 44 so that the ball 45 shrinks into the inside of the sealing block 40. After the notch 42 opened on the sealing block 40 corresponds to one of the groups of water pipes 35, the ball 45 at this time corresponds to the ball groove 46, and then the elastic force of the spring 43 causes the ball 45 to push into the ball groove 46 to limit the sealing block 40.

[0040] Working principle: When treating wastewater, the connecting pipe 32 is connected to the cleaning equipment, and the cleaned wastewater will enter the connecting pipe 33 through the connecting pipe 32. After the wastewater enters the connecting pipe 33, the wastewater will enter the water delivery pipe 35 corresponding to the notch 42 through the notch 42, and then enter the butt joint pipe 36 through the delivery pipe. Then, the wastewater is transported to the filter tank 4 for filtering through the cover body 12 and the water inlet pipe 11. In this process, after the wastewater enters the cover body 12, the wastewater will impact the blade 27, causing the blade 27 to rotate along the axis of the cover body 12, and then the sealing ring 13 is driven to rotate through the rotation of the blade 27, and the rotation of the sealing pipe will drive The rotating plate 28 rotates, and the rotation of the rotating plate 28 drives the connecting shaft 29 to rotate, thereby driving the first flat gear 30 to rotate, and the action of the first flat gear 30 drives the second flat gear 31 to rotate, thereby driving the rotating shaft 25 fixedly connected thereto to rotate, and the action of the rotating shaft 25 drives the prismatic column 24 slidably connected thereto to rotate, and the rotation of the prismatic column 24 drives the rotating column 22 to rotate, thereby driving the insertion rod 20 to rotate, and the action of the insertion rod 20 drives the connecting column 9 to rotate, thereby driving the reciprocating screw 8 to rotate, because the water will fall on the filter element 6 after entering the inside of the filter tank 4, so the filter element 6 is tightly connected to the reciprocating screw 8 through the gravity of the water, so through the reciprocating screw The rotation of the screw rod 8 will drive the filter element 6 to move downward. After moving downward to the bottom end of the reciprocating screw rod 8, the filter element 6 will move upward in the opposite direction under the continuous rotation of the reciprocating screw rod 8, and then the filter element 6 will reciprocate through the rotation of the reciprocating screw rod 8. After the filter element 6 rises to the top of the reciprocating screw rod 8, the filter element 6 needs to be cleaned. In this solution, the diameter of the first flat gear 30 is smaller than the diameter of the second flat gear 31. Therefore, when the first flat gear 30 rotates, it will drive the second flat gear 31 to rotate slower, thereby making the rotation speed of the reciprocating screw rod 8 slower, thereby making the filter element 6 move slower, ensuring that the filter element 6 can filter the wastewater to the maximum extent. At this time, by starting the motor 38, through The action of the motor 38 drives the driving shaft 39 to rotate, and the rotation of the driving shaft 39 drives the sealing block 40 to rotate, so that the gap 42 rotates to correspond to another set of water pipes 35. At this time, the wastewater will enter the other set of filter tanks 4 through the gap 42 for filtration. In this scheme, during the rotation of the sealing block 40, the ball 45 will squeeze the spring 43 through the sliding column 44 so that the ball 45 shrinks to the inside of the sealing block 40. After the gap 42 opened on the sealing block 40 corresponds to one of the sets of water pipes 35, the ball 45 at this time corresponds to the ball groove 46, and then the elastic force of the spring 43 causes the ball 45 to push into the ball groove 46 to limit the sealing block 40.

[0041] In this solution, when cleaning the filter element 6, by rotating the rotating disk 47, the rotating disk 47 drives the fixed column 48 to slide inside the first sliding groove 49 and the second sliding groove 51. When the fixed column 48 slides to the ends of the first sliding groove 49 and the second sliding groove 51, since the diameter of the through hole 52 is larger than the diameter of the limit block 50, the limit block 50 cannot limit the fixing ring 15 at this time, and then the fixing ring 15 is slid upward, and the movable tube 14 is driven to move upward by the action of the fixing ring 15, so that the movable tube 14 is separated from the filter tank 4. When the movable tube 14 moves upward, the rotating column 22 will be driven upward by the action of the fixed seat 23, thereby driving the insertion rod 20 upward. The filter element 6 is disengaged from the slot 21, and the filter element 6 is now located on the connecting column 9. Since the insertion rod 20 is disengaged from the slot 21, the filter element 6 can be directly taken out to be rinsed and cleaned. After cleaning, the filter element 6 is installed on the connecting column 9, and then the movable tube 14 is pulled down, and the rotating disk 47 is rotated in the opposite direction to make the fixed column 48 slide to the other end of the first sliding groove 49 and the second sliding groove 51. At this time, the limit block 50 limits the fixing ring 15, so that the movable tube 14 is stably connected to the filter tank 4. At this time, the movable tube 14 moves downward to drive the rotating column 22 and the insertion rod 20 to move downward, and the insertion rod 20 will be inserted into the slot 21 again.
