Description

Technical Field

[0001] This application relates to the technical field of water purification equipment, and in particular to an ultrapure water instrument for the selection and breeding of highly resistant Camellia oleifera. Background Technology

[0002] Camellia oleifera is an important woody oilseed tree species in my country with high economic value. However, during cultivation, it is susceptible to environmental changes and pests and diseases, leading to a decline in yield and quality. Therefore, selecting varieties with high stress resistance can improve its adaptability and resilience, ensuring healthy growth and maintaining both yield and quality.

[0003] In the breeding of highly resistant Camellia oleifera, the use of an ultrapure water system provides high-purity water, which helps ensure the success of the breeding work. An ultrapure water system can remove impurities, microorganisms, and organic matter from the water, providing high-purity water and avoiding the impact of water quality on the breeding process. The breeding process requires water with high purity requirements, which an ultrapure water system can meet. Therefore, using an ultrapure water system can provide high-purity water, ensuring the success of the breeding work.

[0004] Existing ultrapure water systems only perform simple filtration during water pretreatment. Furthermore, the filtered material accumulates on the filter plate, which not only reduces the water supply due to clogging of the filter holes, but also causes the water medium to pass through the filtered impurities first during the filtration process, thus degrading the quality of the input water and directly affecting the performance and lifespan of the pure water treatment equipment. Summary of the Invention

[0005] This application proposes an ultrapure water system for the selection and breeding of highly resistant Camellia oleifera, which has the advantages of high-pressure backwashing and real-time sewage discharge, in order to solve the problems mentioned in the background art of filter pore blockage being difficult to clean and filter residue affecting the output water quality.

[0006] To achieve the above objectives, this application adopts the following technical solution: an ultrapure water apparatus for the selection and breeding experiment of highly resistant Camellia oleifera, comprising: a body, with a primary water filter tank fixed to the back for coarse filtration of water; a fixed base, fixed to the top of the primary water filter tank, with a pressure regulating base movably sleeved on the outer side of the fixed base, the pressure regulating base being movably sleeved with the inner side of the primary water filter tank; a water storage chamber, formed by the bottom of the pressure regulating base and the inner side of the primary water filter tank, with an inlet pipe fixed to the bottom of the outer side of the primary water filter tank supplying water medium into the water storage chamber; and a drain pipe, fixed to the fixed base. The middle section has a drain pipe that connects to the water storage chamber; a filter disc is fixed inside the pressure regulating seat and located below the fixed seat, and a primary filtration chamber is formed between the surface of the filter disc, the inner side of the pressure regulating seat, and the bottom of the fixed seat; electrical detection contacts are symmetrically arranged inside the body, and when the electrical detection contacts come into contact with the water flow, they energize the coil fixed at the top of the inner side of the primary water filter tank and generate magnetism; a fixed magnetic block is fixed on the surface of the pressure regulating seat, and the magnetic attraction between the fixed magnetic block and the coil is strong; a reset push spring is located between the surface of the pressure regulating seat and the top of the inner side of the primary water filter tank.

[0007] Furthermore, the surface area of ​​the filter disc (15) is 6-8 times the end area of ​​the drain pipe (4), and the inlet pipe and the drain pipe are pipes with the same inner diameter.

[0008] Furthermore, the water storage chamber also includes: a fixed pipe, fixed in the middle of the filter disc; a transmission rod, movably sleeved at the bottom of the fixed pipe, with an upper limit stop fixedly connected to the top of the transmission rod, the upper limit stop being movably sleeved with the inner side of the fixed pipe, and the top of the upper limit stop communicating with the primary filtration chamber; a leak-proof block is fixedly installed at the bottom of the transmission rod, and the leak-proof block is used to seal the sewage channel opened at the bottom of the primary water filtration tank; and a lower limit stop, fixedly connected to the side wall of the transmission rod, and the lower limit stop is located below the bottom of the fixed pipe.

[0009] Furthermore, the bottom area of ​​the pressure regulating seat is 4-6 times the surface area of ​​the filter disc.

[0010] Furthermore, a pressure boosting block is movably mounted on the surface of the pressure regulating seat, and an anti-detachment ring located above the pressure regulating seat is fixedly connected to the outer side of the pressure boosting block. A movable gear seat is fixedly connected to the surface of the pressure boosting block, and a gear that meshes with the outer teeth of the movable gear seat is movably mounted on the surface of the pressure regulating seat. A fixed gear seat is fixedly connected to the top inner side of the primary water filter tank, and the fixed gear seat meshes with the outer teeth of the gear.

[0011] Furthermore, the anti-detachment ring is made of rubber.

[0012] Furthermore, the electrical detection contact is disposed between the filter disc and the pressure regulating seat.

[0013] Furthermore, the surface shape of the booster block is C-shaped.

[0014] The present invention has the following beneficial effects:

[0015] This application provides an ultrapure water system for the selection and breeding of highly resistant Camellia oleifera. The filter disc can move up and down with the pressure regulating seat. When the bottom of the filter disc becomes blocked, the water pressure in the water storage chamber will cause the filter disc to tend to drive the pressure regulating seat upward. Then, the electrical detection contact connects the coil through the water medium. The magnetism generated by the coil attracts the fixed magnetic block, thereby forcibly driving the pressure regulating seat upward. The water medium in the primary filtration chamber is ejected from the filter disc under high pressure, realizing the effect of high-pressure backflushing to clear the blockage.

[0016] Meanwhile, this application has a transmission rod installed in the fixed pipe, and a leak-proof plug is fixed to the end of the transmission rod to block the sewage channel. The leak-proof plug will open the sewage channel after the high-pressure backwash of the filter disc, so that all the backwashed sewage is discharged, avoiding the phenomenon of sewage residue, and ultimately achieving the purpose of real-time and rapid sewage discharge.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] Example 1

[0028] Please see Figure 1 It can be seen that the machine 1 performs primary filtration of water through the primary water filter tank 2 fixed on its back, thereby filtering out large particulate impurities. Figures 2-4 As can be seen, a fixed base 5 is fixedly installed on the top of the primary water filter tank 2, and a pressure regulating base 13 is movably sleeved on the outer side of the fixed base 5. The pressure regulating base 13 is movably sleeved on the inner side of the primary water filter tank 2. During the up and down movement of the pressure regulating base 13, the inner side of the primary water filter tank 2 slides relative to the outer side of the pressure regulating base 13, and the inner side of the pressure regulating base 13 also slides relative to the outer side of the fixed base 5. The bottom of the pressure regulating base 13 and the inner side of the primary water filter tank 2 form a water storage chamber 100. Water medium is input into the water storage chamber 100 through the water inlet pipe 3 fixed on the bottom of the outer side of the primary water filter tank 2. The water inlet pipe 3 can realize the continuous supply of external water medium into the water storage chamber 100. A drain pipe 4 is fixed in the middle of the fixed base 5 to output the water medium in the water storage chamber 100 to the outside of the primary water filter tank 2. The water medium output through the drain pipe 4 should also pass through other filtration systems, such as activated carbon filtration.

[0029] A filter disc 15 located below the fixed base 5 is fixedly installed on the inner side of the pressure regulating base 13. A primary filtration chamber 130 is formed between the surface of the filter disc 15, the inner side of the pressure regulating base 13, and the bottom of the fixed base 5. During the process of water medium in the water storage chamber 100 being transported to the drain pipe 4, the filter holes opened on the filter disc 15 perform coarse filtration on the water medium in the water storage chamber 100, so that large particulate impurities in the water storage chamber 100 are blocked below the filter disc 15.

[0030] There are two electrical detection contacts 9 fixed on the inner side of the body 1, located above the pressure regulating seat 13. The two electrical detection contacts 9 are arranged symmetrically. When the water surface comes into contact with the electrical detection contacts 9, the two electrical detection contacts 9 will be connected, thereby energizing the coil 17 fixed on the top of the inner side of the primary water filter tank 2 and generating magnetism. When the coil 17 generates magnetism, it will attract the fixed magnetic block 18 on the surface of the pressure regulating seat 13. Through the magnetic attraction between the coil 17 and the fixed magnetic block 18, the pressure regulating seat 13 is forced to drive the filter disc 15 to move upward.

[0031] In order to enable the voltage regulating seat 13 to reset autonomously, combined with Figure 4A reset spring 16 is provided between the surface of the pressure regulating seat 13 and the top of the inner side of the primary water filter tank 2. The spring force of the reset spring 16 will make the pressure regulating seat 13 always tend to push upward, thereby overcoming the water pressure of the medium in the water storage chamber 100.

[0032] During use, the water inlet pipe 3 continuously inputs external water medium into the water storage chamber 100. The water medium in the water storage chamber 100 is filtered by the filter plate 15 and then enters the primary filter chamber 130. The water medium in the primary filter chamber 130 is discharged outward through the drain pipe 4. At this time, the filtered impurities will remain at the bottom of the filter plate 15.

[0033] As the filter disc 15 continuously filters, impurities clog the filter holes on the filter disc 15, causing the medium in the water storage chamber 100 to flow poorly into the primary filtration chamber 130. The pressure in the water storage chamber 100 will continuously increase, thereby pushing the filter disc 15 and the pressure regulating seat 13 upward and overcoming the elastic force of the reset push spring 16. As the pressure regulating seat 13 moves upward, the liquid level of the water medium in the water storage chamber 100 also rises. After the water medium contacts the electrical detection contact 9, the electrical detection contacts 9 are connected through the water medium, forcing the coil 17 to be energized. The magnetism generated by the coil 17 attracts the fixed magnetic block 18, causing the pressure regulating seat 13 to drive the filter disc 15 to move upward. The filter disc 15 squeezes the water medium in the primary filtration chamber 130, causing the water medium in the primary filtration chamber 130 to be ejected from the filter disc 15 after being pressurized. At this time, the direction of the jet is downward, thereby achieving high-pressure backflushing of the filter holes on the filter disc 15 and preventing the filter disc 15 from becoming clogged.

[0034] In the implementation of this application, in order to prevent the water medium in the primary filtration chamber 130 from being rapidly output into the drain pipe 4, the inlet pipe 3 and the drain pipe 4 are set as pipes with the same inner diameter, and the surface area of ​​the filter plate 15 is 6-8 times the end area of ​​the drain pipe 4. Since the surface area of ​​the filter plate 15 is much larger than the end area of ​​the drain pipe 4, a small amount of pressurized water medium flows out from the drain pipe 4 during the upward movement of the filter plate 15, while a large amount of water medium will flow downward and pass through the filter holes in the filter plate 15.

[0035] Example 2

[0036] Based on Example 1, please refer to Figures 3-5 A fixed tube 14 is fixed in the middle of the filter disc 15. The transmission rod 12 is movably sleeved on the bottom of the fixed tube 14, and an upper limit stop 121 is fixedly connected to the top of the transmission rod 12. The upper limit stop 121 is movably sleeved on the inner side of the fixed tube 14. The top of the upper limit stop 121 is connected to the primary filter chamber 130. Therefore, when the pressure of the medium in the primary filter chamber 130 increases, it will force the upper limit stop 121 to move downward.

[0037] A leak-proof plug 10 is fixedly installed at the bottom of the transmission rod 12. The leak-proof plug 10 is used to block the drain channel 101 opened at the bottom of the primary water filter tank 2, thereby preventing the water medium in the water storage chamber 100 from leaking out. When the leak-proof plug 10 opens the drain channel 101, the drain channel 101 can output the sewage in the water storage chamber 100 to the outside, preventing sewage from remaining in the water storage chamber 100.

[0038] The transmission rod 12 is fixedly connected to a lower limit stop 120 located below the bottom end of the fixed tube 14. Pushing the lower limit stop 120 according to the bottom end of the fixed tube 14 can cause the anti-leakage blockage 10 to block the sewage channel 101.

[0039] In use, the anti-leakage blockage 10 seals the drain 101, and the water medium in the water storage chamber 100 is filtered as described in Embodiment 1.

[0040] When the filter disc 15 is blocked, causing the pressure regulating seat 13 to rise, the coil 17 is energized and pulls the pressure regulating seat 13 upward via the fixed magnetic block 18. At the same time, the fixed tube 14 follows the filter disc 15 upward. Due to the increased pressure in the primary filter chamber 130, the upper limit stop 121 has a continuous downward pushing force, and the upper limit stop 121 cannot follow the fixed tube 14 upward. When the filter disc 15 is about to touch the bottom of the fixed seat 5, the upper limit stop 121 moves to the bottom of the fixed tube 14. As the fixed tube 14 continues to follow the filter disc 15 upward, the fixed tube 14 pulls the upper limit stop 121 upward, causing the transmission rod 12 to pull the anti-leakage blockage 10 upward, and the sewage discharge channel 101 is opened.

[0041] At this time, after the sewage in the drain 101 is discharged, the water volume in the water storage chamber 100 will decrease rapidly, causing the sewage in the water storage chamber 100 to be discharged quickly. When the liquid level in the water storage chamber 100 is lower than the electrical detection contact 9, the electrical detection contact 9 will be disconnected, and the coil 17 will no longer be energized. Under the action of the gravity of the pressure regulating seat 13 and the elastic force of the reset push spring 16, the pressure regulating seat 13 is pushed downward. As the filter disc 15 moves away from the primary filter chamber 130, the pressure in the primary filter chamber 130 decreases, combined with... Figure 4 It can also be seen that a one-way valve is installed in the drain pipe 4, so the water medium in the drain pipe 4 cannot flow back into the primary filter chamber 130. This forces the upper limit stop 121 to move upward due to the decrease in pressure in the primary filter chamber 130, and the lower limit stop 120 to press against the bottom of the fixed pipe 14. The anti-leakage blockage 10 moves away from the sewage channel 101. Furthermore, as the pressure regulating seat 13 moves downward, the airflow squeezed downward by the pressure regulating seat 13 makes the sewage channel 101 drain faster until all the sewage in the water storage chamber 100 is discharged.

[0042] Finally, after the surface of the continuously descending pressure regulating seat 13 passes the electrical detection contact 9, when the bottom end of the fixed tube 14 pushes the lower limit stop 120 to continue descending, the anti-leakage blockage 10 will block the drain channel 101, thereby preventing the water in the water storage chamber 100 from leaking out. As the water medium is continuously input into the water inlet pipe 3, the filter disc 15 performs filtration again. Afterwards, when the filter disc 15 is blocked again, the cycle is repeated as described above.

[0043] Example 3

[0044] Based on implementation two, please refer to Figure 3 and Figure 4 In order to enhance the unclogging strength of the filter disc 15, the bottom area of ​​the pressure regulating seat 13 is 4-6 times the surface area of ​​the filter disc 15. As the pressure regulating seat 13 moves upward, the pressure in the primary filtration chamber 130 will increase, and the pressure in the water storage chamber 100 will decrease sharply due to the upward movement of the pressure regulating seat 13. This increases the pressure difference between the primary filtration chamber 130 and the water storage chamber 100, further enhancing the flow of water medium from the primary filtration chamber 130 into the water storage chamber 100.

[0045] To further reduce the pressure in the water storage chamber 100, in this third embodiment, a pressure boosting block 11 is movably mounted on the surface of the pressure regulating seat 13, and an anti-detachment ring 110 is fixedly connected to the outer side of the pressure boosting block 11, located above the pressure regulating seat 13. The anti-detachment ring 110 can limit the downward movement of the pressure boosting block 11. A movable gear seat 8 is fixedly connected to the surface of the pressure boosting block 11, and a gear 7 that meshes with the external teeth of the movable gear seat 8 is movably mounted on the surface of the pressure regulating seat 13. A fixed gear seat 6 is fixedly connected to the top of the inner side of the primary water filter tank 2, and the fixed gear seat 6 meshes with the external teeth of the gear 7. Thus, when the pressure regulating seat 13 moves upward, the gear 7 meshes with the fixed gear seat 6 and the movable gear seat 8, forcing the pressure boosting block 11 to move further upward, thereby further reducing the pressure in the water storage chamber 100.

[0046] In use: When the pressure regulating seat 13 moves upward and the electrical detection contact 9 contacts the medium in the water storage chamber 100, the magnetic attraction between the coil 17 and the fixed magnetic block 18 forces the pressure regulating seat 13 to move upward quickly. At the same time as the pressure regulating seat 13 moves upward, the meshing between the gear 7 and the fixed gear seat 6 will force the movable gear seat 8 to move upward. The upward movement of the movable gear seat 8 will cause the pressure in the water storage chamber 100 to decrease further, thereby increasing the pressure difference between the primary filter chamber 130 and the water storage chamber 100.

[0047] When the filter disc 15 approaches the fixed seat 5, the upward pressure regulating seat 13 reaches its limit. At this time, the anti-leakage blockage 10 opens the drain channel 101, and the gear 7 moves to the top of the fixed gear seat 6 and disengages from the teeth of the fixed gear seat 6. Since the medium height in the water storage chamber 100 has exceeded the electrical detection contact 9, the connection of the electrical detection contact 9 will always keep the pressure regulating seat 13 from falling. During the period when the liquid level in the water storage chamber 100 is lower than the electrical detection contact 9, the drain channel 101 will continuously discharge sewage outward. At the same time, the pressure boosting block 11 moves downward under gravity, thereby accelerating the discharge of sewage in the water storage chamber 100. Furthermore, during the downward movement of the movable gear seat 8, the gear 7 will not contact the fixed gear seat 6 and rotate until the liquid level in the water storage chamber 100 is lower than the electrical detection contact 9. Then, the coil 17 is de-energized, the pressure regulating seat 13 moves downward again, and then the drain channel 101 is blocked again as described in Embodiment 2.

[0048] As the pressure regulating seat 13 descends, the movable gear seat 8 has already descended a certain distance following the pressure booster block 11. When the gear 7 meshes with the fixed gear seat 6 again, the rotation of the gear 7 causes the movable gear seat 8 to descend again until the gear 7 meshes with the top of the movable gear seat 8. During the process of the movable gear seat 8 pressing the top of the gear 7, the anti-disengagement ring 110 is made of rubber and has a certain elasticity, which causes the movable gear seat 8 and the gear 7 to temporarily disengage. After the external teeth on the gear 7 move away from the movable gear seat 8, the elasticity of the anti-disengagement ring 110 will cause the movable gear seat 8 to come close to the gear 7 again, so that the gear 7 and the movable gear seat 8 are always in contact, making it easy for the gear 7 and the movable gear seat 8 to mesh quickly when the pressure regulating seat 13 moves upward.

[0049] Example 4

[0050] Based on Example 3, please refer to Figure 4 Because there are wear and leakage problems between the inner side of the pressure regulating seat 13 and the primary water filter tank 2, the inner side of the pressure regulating seat 13 and the outer side of the fixed seat 5, and between the pressure boosting block 11 and the pressure regulating seat 13, when any of these three leaks, the unclogging function of the filter disc 15 will fail or the unclogging effect will be significantly reduced. In order to enable it to automatically provide a warning when there is a leak, the electrical detection contact 9 is set in the area of ​​the surface of the filter disc 15 and the pressure regulating seat 13. Since the height of the electrical detection contact 9 is lower than that of the filter disc 15, when there is a leak between the pressure regulating seat 13 and the pressure boosting block 11, or between the pressure regulating seat 13 and the primary water filter tank 2, the medium in the water storage chamber 100 will flow from the leak to the surface of the pressure regulating seat 13, thereby making the electrical detection contact 9 continuously connected, causing the drain pipe 4 to be unable to receive water normally. At the same time, the water medium in the water storage chamber 100 will frequently be output from the sewage channel 101.

[0051] Combination Figure 6It can be seen that the surface shape of the booster block 11 is C-shaped, ensuring that when there is a leak between the inner side of the booster block 11 and the pressure regulating seat 13, the water in the water storage chamber 100 will quickly flow into each surface of the pressure regulating seat 13. At the same time, when a leak occurs between the fixed seat 5 and the pressure regulating seat 13, the water medium in the primary filtration chamber 130 will not accumulate on the inner side of the pressure regulating seat 13, ensuring the stability of the connection between the electrical detection contacts 9; because the booster block 11 is arranged in a C-shape, combined with Figure 4 It can be clearly seen that the reset push spring 16 and the fixed magnet 18 are both set at the C-shaped notch position of the pressure boosting block 11, further utilizing the surface space of the pressure regulating seat 13, making the structure more compact.
