Description

Technical Field

[0001] This invention belongs to the field of rice breeding technology and equipment, and particularly relates to a low-temperature cold water treatment, purification, filtration and backwashing system for rice temperature-sensitive male sterile lines. Background Technology

[0002] This equipment is a professional instrument and device serving the "two-line hybrid rice breeding technology". It is mainly used in the hybrid breeding and original seed production process of rice. By controlling the environment, assisting in the identification of fertility traits, and identifying and screening the sterility initiation temperature, it enables the efficient cultivation and application of temperature-sensitive male sterile rice lines.

[0003] Existing cold water treatment equipment for rice temperature-sensitive male-sterile lines lacks the function of regulating the water level in the cold water treatment tank during the treatment of male-sterile lines. Furthermore, the required height for cold water treatment varies depending on the variety and growth stage of the plants. Therefore, existing equipment cannot meet the water level requirements of different varieties and growth stages. In addition, the existing equipment has limited ability to regulate water temperature during the cold water treatment process, resulting in poor treatment effects and an inability to accurately identify the sterility threshold temperature of the male-sterile line or screen for fertile, stable male-sterile individual plants.

[0004] Therefore, it is necessary to invent a low-temperature cold water treatment, purification, filtration, and backwashing system for rice temperature-sensitive male sterile lines to solve the above problems. Summary of the Invention

Detailed Implementation

[0054] 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.

[0055] This invention provides, for example Figures 1 to 8The system described herein is a low-temperature cold water treatment, purification, filtration, and backwashing system for a temperature-sensitive male-sterile rice line. It includes: a cold water treatment tank 1, a sedimentation tank 2, a cooling device, piping equipment, and a water level regulating device. Two symmetrically arranged cold water treatment tanks 1 are used to hold seedlings to be selected. Temperature sensors 42 are installed in the treatment area of ​​each cold water treatment tank 1 to monitor the water temperature. The sedimentation tank 2 is located between the two cold water treatment tanks 1 and is used to filter and settle the tap water flowing through them. The cooling device is used to cool the tap water flowing through the cold water treatment tanks 1. Piping equipment connects the cold water treatment tank 1, the sedimentation tank 2, and the cooling device to allow tap water flow between them. The water level regulating device includes a baffle 3, a trapezoidal plate 4, an L-shaped enclosure 5, and a sealing assembly. Plate 3 is vertically installed in the cold water treatment tank 1 to divide the cold water treatment tank 1 into a treatment area and an operation area. The operation area is closer to the sedimentation tank 2 than the treatment area. Trapezoidal plate 4 is installed on the side of baffle 3 near the operation area. There is a gap between the top of trapezoidal plate 4 and the inner wall of the cold water treatment tank 1 near the sedimentation tank 2. A flow guiding component is connected between the operation area and the sedimentation tank 2. Each horizontal step of trapezoidal plate 4 has an overflow hole 6 through it to control the water level when selecting seedlings of different heights in conjunction with the sealing component. L-shaped enclosure 5 is connected in the operation area to divide the operation area into two spaces in conjunction with trapezoidal plate 4 and the side wall of cold water treatment tank 1. The top of L-shaped enclosure 5 is higher than the top of trapezoidal plate 4. A first filter screen 7 is installed on L-shaped enclosure 5. A filter collection component is also installed in the sedimentation tank 2.

[0056] The cooling device includes: a water storage tank 8, a chiller unit 9, an inlet pipe 10, and a delivery pipe 12. The water storage tank 8 is used to store tap water; the chiller unit 9 is used to cool the tap water in the water storage tank 8; the inlet pipe 10 is connected to the water storage tank 8 and is used to inject tap water into the water storage tank 8, and a thin ball valve 11 for controlling the water inlet is installed on the inlet pipe 10; the delivery pipe 12 is connected between the water storage tank 8 and the chiller unit 9, and a first water pump 14 is installed on the delivery pipe 12.

[0057] The piping system includes a return pipe 15, a pumping pipe 17, and a connecting pipe 19. The return pipe 15 connects the treatment area and the operating area of ​​the cold water treatment tank 1, and a second water pump 16 is installed on the return pipe 15 to pump the tap water flowing into the operating area back to the treatment area. The connection between the return pipe 15 and the operating area is located in a separate area enclosed by the L-shaped partition 5. One end of the return pipe 15 connected to the treatment area is connected to an outlet pipe 44, and the length of the outlet pipe 44 matches the internal length of the cold water treatment tank 1. The pumping pipe 17 connects the sedimentation tank 2 and the water storage tank 8. Between them, a self-priming pump 18 is installed on the water pumping pipe 17 to pump the filtered and settled tap water in the sedimentation tank 2 into the water storage tank 8, so that it can be cooled by the chiller unit 9; the connecting pipe 19 is connected between the two return pipes 15 and the water storage tank 8, and an electric proportional valve 20 is connected to the connection point of the connecting pipe 19 and the two return pipes 15 to control the proportion of cooled tap water flowing from the water storage tank 8 into the cold water treatment pool 1; a filter 21 is connected to the connection point of the connecting pipe 19 and the water storage tank 8 to filter the tap water flowing out of the water storage tank 8;

[0058] The sealing assembly includes a sealing plate 22, a first pusher 23, and an L-shaped rod 24. The sealing plate 22 is disposed on the top of the overflow hole 6, and a soft rubber plug matching the overflow hole 6 is connected to the bottom of the sealing plate 22. The first pusher 23 can be an electric push rod, which is vertically fixedly connected to the top of the sealing plate 22 and is used to drive the sealing plate 22 to move in the vertical direction. The L-shaped rod 24 is fixedly connected to the cold water treatment tank 1, and the first pusher 23 is fixedly installed on the L-shaped rod 24.

[0059] During treatment, the selected rice temperature-sensitive male-sterile lines are placed into the treatment zones of two cold water treatment tanks 1. Then, the thin ball valve 11 is opened, and tap water is injected into the storage tank 8 through the inlet pipe 10. Next, two electric proportional valves 20 are opened, and the second water pump 16 is started. This allows the tap water in the storage tank 8 to be pumped into the two cold water treatment tanks 1 through the connecting pipe 19 and the outlet pipe 44 by the second water pump 16. As the water in the storage tank 8 enters the connecting pipe 19, the filter 21 filters the tap water, preventing rust and impurities from entering the cold water treatment tanks 1. As the water level in the cold water treatment tanks 1 gradually rises, when the water level in the cold water treatment tanks 1 is higher than the top of the baffle 3, the water in the treatment zone can overflow the top of the baffle 3 and contact the trapezoidal plate 4. At this time, the water level in the treatment zone can be adjusted according to the height of the young panicles at different stages of the plant growth. The specific adjustment operation is as follows:

[0060] When the water level requirement in the treatment area is low, the sealing plate 22 on the lowest step of the trapezoidal plate 4 can be moved upward by the pulling action of the first pushing member 23 connected to it, so that the soft rubber plug at the bottom of the sealing plate 22 on the lowest step can be pulled out from the corresponding overflow hole 6. At this time, the overflow hole 6 on the lowest step is in the open state. Therefore, when the water level is flush with the lowest step of the trapezoidal plate 4, excess tap water can flow into the operation area through the overflow hole 6. Then, the height of the guide component is adjusted according to the height of the water level in the cold water treatment tank 1 to prevent tap water from entering the sedimentation tank 2 through the guide component.

[0061] When the required water level in the treatment area is high, first determine the required water level in the treatment area, and then open the overflow hole 6 at the corresponding height on the trapezoidal plate 4 in the manner described above. At the same time, keep the other sealing plates 22 closed to seal the overflow hole 6 on the corresponding step surface. At this time, as the second water pump 16 continuously pumps tap water into the cold water treatment tank 1, the water level in the treatment area can gradually rise under the obstruction of the trapezoidal plate 4 until the water level in the treatment area reaches the specified height. Then, the excess water can flow into the operation area through the overflow hole 6.

[0062] Once the water level in the treatment area reaches the predetermined height, tap water continues to be supplied to the cold water treatment tank 1, thereby ensuring that the water in the cold water treatment tank 1 can circulate between the operating area and the treatment area under the action of the pipeline equipment. After the tap water supply is completed, the thin ball valve 11 is closed. At the same time, while keeping the electric proportional valve 20 closed, the second water pump 16 is kept running. At this time, the water in the operating area can flow to the area of ​​the L-shaped enclosure 5 under the action of the second water pump 16. Then, the tap water filtered by the first filter screen 7 can flow back to the treatment area through the return pipe 15, thereby realizing the circulation operation of tap water in the cold water treatment tank 1, so that the overall water temperature in the cold water treatment tank 1 can be kept stable and uniform.

[0063] When water temperature adjustment is needed, temperature sensor 42 monitors the water temperature in cold water treatment tank 1. If the water temperature is too high, the guide height of the guide component is manually adjusted so that tap water in the operating area can flow into sedimentation tank 2. The tap water entering sedimentation tank 2 is then filtered by the filter collection component, removing impurities (silt, seedlings, withered leaves, etc.). Subsequently, the self-priming pump 18, electric proportional valve 20, and the first water pump 14 are activated. At this time, the water in sedimentation tank 2 has undergone... Filtered tap water can enter the water storage tank 8 through the pump pipe 17 under the action of the self-priming pump 18. Then, the tap water in the water storage tank 8 can enter the chiller unit 9 through the delivery pipe 12 under the action of the first water pump 14 for cooling. After the tap water is cooled, the tap water in the chiller unit 9 can flow back to the water storage tank 8 through the return water pipe 13. Then, the cooled tap water can be transported back to the cold water treatment tank 1 through the connecting pipe 19, thereby realizing the regulation of the water temperature in the cold water treatment tank 1.

[0064] Furthermore, due to the presence of the outlet pipe 44, when the cooled tap water flows into the cold water treatment tank 1 through the outlet pipe 44, the cooled tap water flowing out of the outlet pipe 44 can mix with the original tap water in the cold water treatment tank 1 over a larger area because the outlet pipe 44 is relatively long, thereby allowing the water temperature in the cold water treatment tank 1 to drop rapidly and evenly.

[0065] like Figures 4 to 6 As shown, the flow guiding assembly includes: an L-shaped flow guiding pipe 25, a flat pipe 26, and a magnetic component 28; the L-shaped flow guiding pipe 25 is connected between the operating area and the sedimentation tank 2, and is used to introduce water from the cold water treatment tank 1 into the sedimentation tank 2 for sedimentation and filtration; the flat pipe 26 is slidably inserted into one end of the L-shaped flow guiding pipe 25 in the operating area, and a strip-shaped water inlet notch 27 is provided on the top edge of the flat pipe 26; the magnetic component 28 can be a magnetic block, which is fixedly connected to the top of the flat pipe 26, and the magnetic component 28 can be attracted to the inner walls of the front and rear sides of the cold water treatment tank 1, so as to fix the flat pipe 26 at different heights according to the water level in the operating area, thereby changing the height of the water inlet notch 27 at the top of the flat pipe 26;

[0066] When the tap water in the cold water treatment tank 1 is not cooled, the magnetic component 28 can be pulled upwards, causing the flat tube 26 to move upwards under the pull of the magnetic component 28. When the top of the flat tube 26 is at a higher position, as the pull of the magnetic component 28 is stopped, the magnetic component 28 can be attracted to the inner wall of the cold water treatment tank 1, thereby locking the current position of the flat tube 26. At this time, the tap water in the operation area cannot enter the flat tube 26 through the water inlet 27 at the top of the flat tube 26, thereby preventing the tap water in the operation area from flowing into the sedimentation tank 2.

[0067] When it is necessary to filter the tap water in the cold water treatment tank 1, the magnetic part 28 can be pressed down so that the water inlet 27 at the top of the flat tube 26 can be immersed in the tap water, so that the tap water in the operation area can enter the L-shaped guide pipe 25 through the flat tube 26, and then the tap water can enter the sedimentation tank 2 through the L-shaped guide pipe 25, thereby realizing the sedimentation and filtration of the tap water.

[0068] like Figure 7 and Figure 8 As shown, the filtration and collection assembly includes: a partition 29, a second pusher 31, a U-shaped plate 32, a sleeve 33, a collection hopper 34, a connecting strip 36, and a rinsing mechanism 37. The partition 29 is vertically slidably inserted into the bottom wall of the sedimentation tank 2, and a second filter screen 30 is installed in the middle of the partition 29. In the initial state, the bottom of the second filter screen 30 is flush with the bottom inner wall of the sedimentation tank 2, and at this time, the bottom of the partition 29 is fully inserted into the sleeve 33. The second pusher 31 can be an electric push rod, which is vertically fixedly connected to the side of the partition 29 away from the collection hopper 34, and is used to drive the partition 29 to move in the vertical direction. The U-shaped plate 32 is fixedly connected to the sedimentation tank 2, and the second pusher 31 is fixedly installed on the U-shaped plate 32. The sleeve 33 is sleeved on the bottom of the partition 29, and the sleeve 33 is connected to the bottom of the sedimentation tank 2. The second filter 30 is connected to the partition 29 and the sedimentation tank 2 to seal the gap at the joint. The collection hopper 34 is detachably installed inside the sedimentation tank 2, and the side of the collection hopper 34 facing the partition 29 is open. The bottom of the collection hopper 34 gradually slopes downward away from the partition 29, and a third filter screen 35 is installed on the bottom inner wall of the collection hopper 34. The connecting strip 36 is connected to the side of the partition 29 near the collection hopper 34, and when the bottom of the second filter screen 30 moves upward to a position flush with the bottom inner wall of the collection hopper 34, the connecting strip 36 can be smoothly connected between the opening side of the collection hopper 34 and the partition 29. The rinsing mechanism 37 is located on the side of the partition 29 away from the collection hopper 34 and is used to backwash the second filter screen 30. The end of the water pump 17 connected to the sedimentation tank 2 is located on the side of the partition 29 near the rinsing mechanism 37.

[0069] The rinsing mechanism 37 includes: a spray pipe array 38 and a fixing plate 41. The spray pipe array 38 is vertically arranged on the side of the partition 29 away from the collection hopper 34. A suction pipe 39 for pumping water is connected to the spray pipe array 38, and a third water pump 40 is installed on the suction pipe 39. The fixing plate 41 is connected to the inner wall of the sedimentation tank 2 for installing the spray pipe array 38. The bottom of the sedimentation tank 2 is lower than the bottom of the cold water treatment tank 1, and a sewage pipe 43 is connected to the bottom of the sedimentation tank 2.

[0070] When the tap water in the operating area of ​​the cold water treatment tank 1 enters the sedimentation tank 2 through the L-shaped guide pipe 25, the self-priming pump 18 pumps the tap water in the sedimentation tank 2 into the water storage tank 8 through the water pumping pipe 17. The tap water in the sedimentation tank 2 can continuously move towards the direction of the water pumping pipe 17. During this process, when the tap water passes through the second filter screen 30 on the partition 29, the second filter screen 30 can filter the tap water in the sedimentation tank 2, so that the impurities such as mud and dead leaves in the tap water can be intercepted by the second filter screen 30. Then the filtered tap water can enter the water storage tank 8 through the water pumping pipe 17, thereby completing the subsequent cooling operation.

[0071] After the second filter screen 30 has been used for a period of time, it may become clogged with impurities such as mud, sand, or dead leaves. At this time, the second pusher 31 can be activated, causing the baffle 29 to move upwards under the pull of the second pusher 31. As the baffle 29 moves upwards, the second filter screen 30 on the baffle 29 gradually moves upwards, and the portion of the baffle 29 located inside the sleeve 33 also moves upwards accordingly, thus gradually blocking the filtered tap water on the side of the baffle 29 near the flushing structure. As the baffle 29 continues to move upwards, when the bottom of the second filter screen 30 is flush with the bottom inner wall of the opening side of the collection hopper 34, the connecting strip 36 can smoothly connect the baffle 29 and the collection hopper 34. At this time, the baffle 29... Before the bottom is completely removed from the sleeve 33, the third water pump 40 is started, so that the suction pipe 39 can spray the filtered tap water through the spray pipe 38 onto the second filter screen 30 under the action of the third water pump 40, thereby realizing the backwashing operation of the second filter screen 30. The mud, sand and dead leaves and other impurities washed down can flow along the connecting strip 36 to the bottom inner wall of the collection hopper 34. Then, the washed sewage can flow along the bottom inner wall of the collection hopper 34 to the area where the third filter screen 35 is located. When the sewage comes into contact with the third filter screen 35, the third filter screen 35 can filter the mud, sand and dead leaves and other impurities in the sewage, so that the impurities can be retained in the collection hopper 34, and the filtered sewage can flow back into the sedimentation tank 2.

[0072] After the second filter screen 30 is rinsed, the third water pump 40 is turned off. At this time, the second pusher 31 can drive the partition 29 to move downward, so that the second filter screen 30 is re-immersed in the tap water, thereby continuing to filter the tap water in the sedimentation tank 2.

[0073] During the process of filtering impurities in the sedimentation tank 2 by the second filter screen 30, since the second filter screen 30 is set vertically, some mud and sand and other impurities will still be deposited on the bottom inner wall of the sedimentation tank 2. At this time, with the flow guide component closed, the drain pipe 43 can be opened to discharge the mud and sand impurities deposited on the bottom inner wall of the sedimentation tank 2 from the sedimentation tank 2, thereby realizing the cleaning and sewage discharge operation inside the sedimentation tank 2 and ensuring the cleanliness of the inside of the sedimentation tank 2.

[0074] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
