Technical Field

[0001] The invention belongs to the field of rice breeding technology and equipment, and in particular relates to a low-temperature cold water treatment, purification, filtration and backwashing system for a thermo-sensitive sterile rice line. Background Art

[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 regulating the environment, assisting in the identification of fertility traits, and identifying and screening the sterility threshold temperature, it can achieve the efficient cultivation and application of rice temperature-sensitive male sterile lines.

[0003] The existing cold water treatment equipment for thermosensitive sterile rice lines lacks the function of regulating the water level of the cold water treatment pool during the treatment of sterile plants. The treated plants require different cold water treatment heights due to different varieties and growth periods. Therefore, the existing cold water treatment equipment for thermosensitive sterile rice lines cannot meet the water level height requirements of plants of different varieties and at different periods. In addition, the existing cold water treatment equipment for thermosensitive sterile rice lines has a general effect on regulating the water temperature during the cold water treatment process, resulting in poor results after cold water treatment, and cannot truly identify the sterility starting temperature of the sterile line and screen out sterile plants with stable fertility.

The trapezoidal plate 4 is arranged on the side of the baffle 3 close to the operation area, and there is a gap between the top of the trapezoidal plate 4 and the inner wall of the cold water treatment tank 1 close to the sedimentation tank 2, and a diversion component is connected between the operation area and the sedimentation tank 2. An overflow hole 6 is opened through each horizontal step surface of the trapezoidal plate 4, which is used to cooperate with the sealing component to realize the control of the water level during the selection and breeding of seedlings of different heights. The L-shaped enclosing plate 5 is connected to the operation area, and is used to cooperate with the trapezoidal plate 4 and the side wall of the cold water treatment tank 1 to divide the operation area into two spaces. The top of the L-shaped enclosing plate 5 is higher than the top of the trapezoidal plate 4, and a first filter screen 7 is installed on the L-shaped enclosing plate 5. A filter collection component is also provided in the sedimentation tank 2;

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

[0057] The pipeline equipment includes: a return pipe 15, a pumping pipe 17 and a connecting pipe 19. The return pipe 15 is connected between the treatment area and the operation area of ​​the cold water treatment tank 1, and a second water pump 16 is installed on the return pipe 15 to cooperate with the return pipe 15 to pump the tap water flowing into the operation area back to the treatment area. The connection between the return pipe 15 and the operation area is located in a separate area surrounded by the L-shaped enclosure 5. The return pipe 15 is connected to the treatment area at one end and is connected to a water outlet pipe row 44, and the length of the water outlet pipe row 44 matches the internal length of the cold water treatment tank 1; the pumping pipe 17 is connected to the sedimentation tank 2 and the water storage tank 8 A self-priming pump 18 is installed on the water pumping pipe 17, which is used to cooperate with the water pumping pipe 17 to pump the tap water that has been filtered and precipitated in the sedimentation tank 2 into the water storage tank 8, so that it is cooled by the refrigeration water unit 9; the connecting pipe 19 is connected between the two return pipes 15 and the water storage tank 8, and the connection between the connecting pipe 19 and the two return pipes 15 is connected to an electric proportional valve 20, which is used to control the proportion of cooled tap water flowing from the water storage tank 8 into the cold water treatment pool 1, and the connection between the connecting pipe 19 and the water storage tank 8 is connected to a filter 21, so as 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 arranged 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 pusher, 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 mounted on the L-shaped rod 24.

[0059] During treatment, the selected thermosensitive sterile rice plants are placed in the treatment areas of the two cold water treatment pools 1 respectively, then the thin ball valve 11 is opened, and tap water is injected into the water storage tank 8 through the water inlet pipe 10, then the two electric proportional valves 20 are opened and the second water pump 16 is started, so that the tap water in the water storage tank 8 can be pumped into the two cold water treatment pools 1 through the connecting pipe 19 and the outlet pipe row 44 under the action of the second water pump 16, and when the water in the water storage tank 8 enters the connecting pipe 19, the filter 21 can filter the tap water, thereby preventing water rust impurities in the tap water from entering the cold water treatment pool 1, as the water level of the cold water treatment pool 1 gradually rises, when the water level in the cold water treatment pool 1 is higher than the top of the baffle 3, the water in the treatment area can overflow the top of the baffle 3 and contact the trapezoidal plate 4, at this time, the water level in the treatment area can be adjusted according to the height of the young spikelets of the plants at different stages, and 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 surface of the trapezoidal plate 4 can be moved upward under the pulling action of the first pusher 23 connected thereto, so that the soft rubber plug at the bottom of the sealing plate 22 on the lowest step surface is pulled out from the corresponding overflow hole 6. At this time, the overflow hole 6 on the lowest step surface is in an open state. Therefore, when the water level is kept flush with the lowest step surface of the trapezoidal plate 4, excess tap water can flow into the operation area through the overflow hole 6. Subsequently, the diversion height of the diversion 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 diversion component.

[0061] When the water level requirement in the treatment area is higher, the required height of the water level in the treatment area is first determined. Then, according to the above method, the overflow hole 6 of the corresponding height on the trapezoidal plate 4 is opened, while the other sealing plates 22 are kept closed to seal the overflow holes 6 on the corresponding step surfaces. 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] When the water level in the treatment area reaches a predetermined height, tap water continues to be introduced into the cold water treatment pool 1, thereby ensuring that the water in the cold water treatment pool 1 can circulate between the operation area and the treatment area under the action of the pipeline equipment. When the tap water is completely introduced, the thin ball valve 11 is closed. At the same time, under the premise of keeping the electric proportional valve 20 closed, the second water pump 16 is kept running. At this time, the water in the operation area can flow to the area of ​​the L-shaped enclosure 5 under the action of the second water pump 16. Subsequently, 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 the tap water in the cold water treatment pool 1, so that the overall water temperature in the cold water treatment pool 1 can be kept stable and uniform.

[0063] When the water temperature needs to be adjusted, the temperature sensor 42 can monitor the water temperature in the cold water treatment pool 1. When it is observed that the water temperature is too high, the diversion height of the diversion component is manually adjusted first, so that the tap water in the operation area can flow into the sedimentation tank 2 through the diversion component. At this time, the tap water entering the sedimentation tank 2 can be filtered by the filter collection component to remove impurities (silt, dead leaves of seedlings, etc.) in the water. Then, the self-priming pump 18, the electric proportional valve 20 and the first water pump 14 are turned on. At this time, the tap water in the sedimentation tank 2 that has passed through the filter collection component is filtered. The filtered tap water can enter the water storage tank 8 through the water suction pipe 17 under the action of the self-priming pump 18, and then the tap water in the water storage tank 8 can enter the refrigeration water unit 9 through the delivery pipe 12 under the action of the first water pump 14 for cooling operation. After the tap water is cooled, the tap water in the refrigeration water unit 9 can flow back to the water storage tank 8 through the return pipe 13, and then the cooled tap water can be transported back to the cold water treatment tank 1 through the connecting pipe 19, thereby achieving the adjustment of the water temperature in the cold water treatment tank 1;

[0064] In addition, due to the presence of the outlet pipe row 44, when the cooled tap water flows into the cold water treatment tank 1 through the outlet pipe row 44, since the outlet pipe row 44 is longer, the cooled tap water flowing out of the outlet pipe row 44 can be mixed with the original tap water in the cold water treatment tank 1 over a larger area, thereby allowing the water temperature in the cold water treatment tank 1 to drop quickly and evenly.

[0065] like Figures 4 to 6 As shown, the diversion assembly includes: an L-shaped diversion pipe 25, a flat tube 26 and a magnetic member 28; the L-shaped diversion pipe 25 is connected between the operation area and the sedimentation tank 2, and is used to guide the water in the cold water treatment tank 1 into the sedimentation tank 2 for sedimentation and filtration; the flat tube 26 is slidably inserted into one end of the L-shaped diversion pipe 25 located in the operation area in the vertical direction, and a strip-shaped water inlet notch 27 is opened on the top edge of the flat tube 26; the magnetic member 28 can be a magnetic block, fixedly connected to the top of the flat tube 26, and the magnetic member 28 can be adsorbed together with the front and rear inner walls of the cold water treatment tank 1, and is used to fix the flat tube 26 at different heights according to the water level in the operation area through the suction force between the magnetic member 28 and the cold water treatment tank 1, thereby changing the height of the water inlet notch 27 at the top of the flat tube 26;

[0066] When the tap water in the cold water treatment tank 1 is not being cooled, the magnetic member 28 can be pulled upward, causing the flat tube 26 to move upward under the pull of the magnetic member 28. When the top of the flat tube 26 is at a high position, the magnetic member 28 stops being pulled, and the magnetic member 28 can be adsorbed together with 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 notch 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 downward so that the water inlet notch 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 effect on the tap water.

[0068] like Figure 7 and Figure 8 As shown, the filter collection assembly includes: a partition 29, a second pusher 31, a U-shaped plate 32, a sleeve plate 33, a collection bucket 34, a connecting strip 36 and a flushing mechanism 37. The partition 29 slides vertically through and is inserted into the bottom box wall of the sedimentation box 2, and a second filter screen 30 is installed in the middle position 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 box 2, and at this time, the bottom of the partition 29 is completely inserted into the sleeve plate 33; the second pusher 31 can be an electric push rod, and the second pusher 31 is vertically fixedly connected to the side of the partition 29 away from the collection bucket 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 box 2, and the second pusher 31 is fixedly installed on the U-shaped plate 32; the sleeve plate 33 is sleeved on the bottom of the partition 29, and the sleeve plate 33 is connected to the bottom of the sedimentation box 2 The connection is used to seal the gap at the connection between the partition 29 and the sedimentation box 2; the collecting hopper 34 is detachably mounted on the inner side of the sedimentation box 2, and the side of the collecting hopper 34 facing the partition 29 is an open design, the bottom of the collecting hopper 34 gradually tilts downward in the direction away from the partition 29, and a third filter screen 35 is installed on the bottom inner wall of the collecting hopper 34; the connecting strip 36 is connected to the side of the partition 29 close to the collecting 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 collecting hopper 34, the connecting strip 36 can be smoothly connected between the open side of the collecting hopper 34 and the partition 29; the flushing mechanism 37 is provided on the side of the partition 29 away from the collecting hopper 34, for backwashing the second filter screen 30, and the end of the water pumping pipe 17 connected to the sedimentation box 2 is located on the side of the partition 29 close to the flushing mechanism 37;

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

[0070] After 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, as the self-priming pump 18 pumps the tap water in the sedimentation tank 2 into the water storage tank 8 through the pumping pipe 17, the tap water in the sedimentation tank 2 can continuously move in the direction of the pumping pipe 17. During this process, when the tap water passes through the second filter 30 on the partition 29, the second filter 30 can filter the tap water in the sedimentation tank 2, so that impurities such as mud, dead leaves, etc. in the tap water can be intercepted by the second filter 30. Then, the filtered tap water can enter the water storage tank 8 through the pumping pipe 17, thereby completing the subsequent cooling operation;

[0071] After the second filter screen 30 has been used for a period of time, the second filter screen 30 may be clogged with impurities such as mud, sand or dead leaves. At this time, the second pushing member 31 can be activated, so that the partition 29 moves upward under the pull of the second pushing member 31. As the partition 29 moves upward, the second filter screen 30 on the partition 29 can gradually move upward, and the part of the partition 29 located in the sleeve plate 33 can also move upward accordingly, thereby gradually isolating the filtered tap water on the side of the partition 29 close to the flushing structure. As the partition 29 continues to move upward, when the bottom of the second filter screen 30 is flush with the bottom inner wall of the opening side of the collection bucket 34, the connecting strip 36 can be smoothly connected between the partition 29 and the collection bucket 34, and at this time the partition 29 The bottom is not completely removed from the sleeve plate 33, and then the third water pump 40 is started, so that the suction pipe 39 can spray the filtered tap water onto the second filter 30 through the spray pipe row 38 under the action of the third water pump 40, thereby realizing the backwash operation of the second filter 30, and the washed-down mud, sand, dead leaves and other impurities can flow along the connecting strip 36 to the bottom inner wall of the collection bucket 34, and then the washed sewage can flow along the bottom inner wall of the collection bucket 34 to the area where the third filter 35 is located. When the sewage contacts the third filter 35, the third filter 35 can filter the mud, sand, dead leaves and other impurities in the sewage, so that the impurities can be retained in the collection bucket 34, and the filtered sewage can flow back to the sedimentation tank 2;

[0072] When the second filter screen 30 is flushed, the third water pump 40 is turned off, and 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 the second filter 30 filtering the impurities in the sedimentation box 2, since the second filter 30 is arranged vertically, some impurities such as mud and sand will be deposited on the bottom inner wall of the sedimentation box 2. At this time, when the diversion component is closed, the drain pipe 43 can be opened to discharge the mud and sand impurities deposited on the bottom inner wall of the sedimentation box 2 from the sedimentation box 2, thereby realizing the cleaning and drainage operation inside the sedimentation box 2 and ensuring the cleanliness of the inside of the sedimentation box 2.

[0074] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
