Description

Technical Field

[0001] The invention relates to the technical field of seedling raising pools, and in particular to a seedling raising pool purification device and method. Background Art

[0002] The seedling pool creates an exclusive growth environment for seedlings and is widely used in the fields of flowers, aquatic seedlings, etc. It can provide water, regulate temperature, assist reproduction and improve hatching rates. It is necessary to filter and purify large particles in the pool, which not only affect the clarity and transparency of the water, but may also clog circulation and filtration equipment, causing water flow and dissolved oxygen problems. In addition, impurities are easy to carry pathogens, increasing the risk of seedlings becoming infected, interfering with their light and nutrient absorption, and hindering their growth.

[0003] There are many impurities in the water quality of the seedling pool, such as undissolved fertilizer particles, aquatic biological debris, introduced dust, equipment wear particles, etc., which will affect the quality of seedlings. Some seedling varieties have strict requirements on water quality. Filtration can remove impurities according to particle size and solubility to achieve the high-standard water quality required for high-quality seedlings, ensure the stable growth and healthy development of seedlings, and have far-reaching significance for seedlings such as flowers and aquatic products. The traditional filtration equipment for the water quality of the seedling pool has a simple structure. Some impurities will cause the filter to be blocked during the filtration process. As the filtration operation proceeds, the filtration efficiency of the filtration structure will be reduced due to blockage. Therefore, it is necessary to regularly clean the filter in the filtration structure to ensure that the seedling water will not be affected by large particles of impurities and can be in an efficient seedling state. Regular cleaning operations are time-consuming and laborious. In the process of filtering the seedling water, a large amount of seedling water is filtered through the filter, which will increase the burden on the filter. It is necessary to shut down the pipeline that transports the seedling water during filtration. After the filtration is completed, the seedling water is introduced into the filter. The operation is cumbersome and the operator cannot master the filtration frequency well, which affects the filtration efficiency.

[0004] Based on this, a seedling raising pool purification device and method are proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a seedling pond purification device and method to solve the above problems.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: The filter screen is connected with a filter screen, and a filter screen is connected with the filter screen.

[0012] Preferably, a connecting seat is connected between the limiting plate and the filter bin, a placing plate is clamped on the connecting seat, and the placing plate is arranged directly below the cleaning plate.

[0013] Preferably, the driving member includes a traction frame, one end of the traction frame is rotatably connected to one end of the sliding rod, a turntable is connected to the outside of the cam, a traction shaft is non-axially connected to the outside of the turntable, and the other end of the traction frame is rotatably connected to the traction shaft.

[0014] A method for purifying a seedling pool, using a seedling pool purification device, comprises the following steps: S1: Pass the seedling water into the mixing chamber, start the motor, drive the cam to rotate, so that the seedling water intermittently enters the filtering chamber through the filter screen; S2: Use the synchronously rotating turntable and the traction shaft to pull the sliding rod to slide on the L-shaped groove, so that after the filter screen filters and purifies the seedling water, the cleaning plate can enter the top of the filter screen to clean the impurities attached to it. After cleaning, the seedling water continues to be discharged and the filtration and purification of the seedling water continues. The purification and cleaning operations are carried out alternately until the seedling water in the mixing bin is filtered and purified.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The present application adopts a filter structure and utilizes a long strip filter structure to increase the filtering effect, avoid serious blockage of filter holes at specific positions on the filter caused by filtering at a single position, and cooperate with the cleaning plate to brush the filter to avoid large particles of impurities from accumulating on the filter and interfering with subsequent filtration. During the cleaning process, the cleaning plate will scrape the bristles through the placement plate to avoid impurities adhering to the bristles, ensuring that the cleaning plate remains clean each time cleaning, thereby improving cleaning efficiency and ensuring that the filter is always in a high-efficiency filtration state.

[0016] 2. The present application adopts a cover plate structure, utilizes the cooperation between the cover plate and the partition plate, and relies on a cam structure to drive the cover plate to rise and fall, so that the seedling water can intermittently complete the feeding and filtering operation, reducing the load of the filter screen for filtering large quantities of seedling water, and utilizes the connection between the cam and the turntable to allow filtering and cleaning to operate alternately, avoiding the movement of the cleaning plate to interfere with the filtering operation of the filter screen, while also maintaining the high-efficiency filtering state of the filter screen, thereby improving the filtering efficiency.

[0019] 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.

[0020] See also Figure 1-Figure 7 , the present invention provides a technical solution: A seedling water pool purification device and method include a filter bin 1 and a shell 34, and a discharge pipe 35 is connected to the shell 34. The shell 34 is a combined structure, wherein the shell 34 on one side of the filter bin 1 and the shell 34 on the side of the limit plate 4 can be assembled by plugging. When the equipment is running, it is necessary to ensure that the shells 34 are closed to each other, so as to facilitate the subsequent cleaning of impurities inside the equipment after the filtration is completed to avoid polluting the working environment. The upper end of the filter bin 1 is connected to the mixing bin 2, and the filter bin 1 and the mixing bin 2 are fixedly connected. A discharge pipe 5 is connected to one side of the mixing bin 2, and the discharge pipe 5 is connected to one side of the lower end of the mixing bin 2. The filtered seedling water can be taken out through the discharge pipe 5. A filter screen 31 is connected to the filter bin 1, and the filter screen 31 needs to adopt an aperture that meets the pore size of large particle impurities in the seedling water, so that during filtration, impurities remain on the filter screen 31, and the seedling water enters the filter bin 1 through the filter screen 31. A partition 23 is connected to the mixing bin 2, and a discharge port 24 is opened on the partition 23. The discharge port 24 is set There are multiple, multiple feed openings 24 evenly opened on the partition 23, a connecting frame 25 is arranged above the partition 23, a cover plate 26 is connected to the lower end of the connecting frame 25, the cover plate 26 corresponds to the feed opening 24 one by one, when the cover plate 26 falls and docks with the feed opening 24, the feed opening 24 can be closed to prevent the seedling water from entering the filter bin 1, the upper end of the connecting frame 25 is connected to the lifting frame 17, one end of the lifting frame 17 is rotatably connected to the roller 18, the filter bin 1 is connected to the motor 19, the motor 19 outputs The outlet end is connected with a cam 7, and the outer side of the cam 7 is in rolling contact with the roller 18. By setting the roller 18 structure, the wear of the structure when the cam 7 supports the lifting frame 17 to perform height lifting is reduced. A side opening 21 is opened on one side of the filter bin 1, and a support frame 3 is arranged on one side of the side opening 21. The upper end of the support frame 3 is connected with a limit plate 4 through a fixed block 20. Two limit plates 4 are arranged. Connecting columns 33 are connected between the limit plates 4. A brushing mechanism for brushing the upper surface of the filter screen 31 is connected between the limit plates 4.

[0021] Specifically, Figure 5 As shown, a deflection rod 29 is fixedly connected in the mixing bin 2, and a plurality of deflection rods 29 are provided. The plurality of deflection rods 29 are symmetrically connected to the inner wall of the mixing bin 2, and a guide plate 30 is connected to the deflection rod 29. The guide plate 30 is provided below the partition 23. By providing the guide plate 30, the seedling water flowing out of the discharge port 24 can be separated into multiple streams, which are then filtered on the filter screen 31 to ensure that the cobalt sulfate is evenly filtered on the filter screen 31, thereby avoiding filtering of the seedling water at a single position on the filter screen 31, causing serious blockage of the filter holes at the corresponding position on the filter screen 31, and increasing the subsequent filtering burden of the filter screen 31.

[0022] Specifically, Figure 5As shown, a plurality of deflection rods 29 and guide plates 30 are provided, and the plurality of guide plates 30 are symmetrically arranged in an inverted eight shape in the mixing chamber 2. The guide plates 30 arranged in an inverted eight shape make the seedling water collide with each other after being guided, thereby improving the mixing effect of the seedling water, so that the seedling water can be mixed evenly before continuing to be filtered. At the same time, the guide plate 30 structure can be adjusted in angle when the deflection rod 29 rotates, and the structure has adjustability.

[0023] Specifically, Figure 5 As shown, a slider 28 is connected to the outside of the connecting frame 25, and a side slide groove 22 is opened on the inner wall of the mixing bin 2. One end of the slider 28 is slidably connected to the side slide groove 22. By setting a structure in which the slider 28 and the side slide groove 22 cooperate with each other, the connecting frame 25 maintains structural stability when it is lifted up and down. The slider 28 adopts a structure in which one end is slidably connected to the side slide groove 22, so that the connecting frame 25 maintains structural stability when it is lifted up and down, and does not tilt.

[0024] Specifically, Figure 5 As shown, a return spring 27 is connected to the connecting frame 25, and a spring plate 16 is connected to the mixing bin 2. The upper end of the return spring 27 is connected to the lower end of the spring plate 16. By setting the return spring 27 structure, when the connecting frame 25 moves downward, the downward operation is completed, avoiding the operation of the cover plate 26 sealing the discharge port 24 cannot be completed quickly due to the effect of gravity, and there is a certain resistance when the connecting frame 25 moves downward in the liquid medium of the seedling water. Therefore, by setting the return spring 27, the stability of the structure of the cover plate 26 sealing the discharge port 24 is improved.

[0025] Specifically, Figure 7 As shown, the brushing mechanism includes a cleaning plate 12, and the lower end of the cleaning plate 12 is connected to bristles 32. The bristles 32 are used to disturb the filter screen 31 to filter out residual impurities, so as to facilitate the subsequent cleaning of the filter screen 31. The cleaning plate 12 is connected to a sliding rod 10 and a sliding rod 2 11. The sliding rod 10 and the sliding rod 2 11 are arranged on the cleaning plate 12 at one end away from the bristles 32, and the sliding rod 10 is arranged on the right side of the sliding rod 2 11. An L-shaped groove 14 is opened on the limiting plate 4. The sliding rod 10 and the sliding rod 2 11 are both slidably connected to the L-shaped groove 14. The sliding rod 10 is connected to a driving member for driving the sliding rod 10 to slide on the L-shaped groove 14.

[0026] Specifically, Figure 6 and Figure 7 As shown, a connecting seat 13 is connected between the limit plate 4 and the filter bin 1, and a placing plate 15 is clamped on the connecting seat 13. By setting the placing plate 15, when the cleaning plate 12 moves, the bristles 32 connected to the cleaning plate 12 can be cleaned to avoid impurities adhering to the bristles 32, thereby causing repeated contamination of the filter screen 31. The placing plate 15 is arranged directly below the cleaning plate 12.

[0027] Specifically, Figure 5 As shown, the driving member includes a traction frame 9, one end of which is rotatably connected to one end of a sliding rod 10, a turntable 6 is connected to the outside of the cam 7, a traction shaft 8 is non-axially connected to the outside of the turntable 6, and the other end of the traction frame 9 is rotatably connected to the traction shaft 8. The eccentrically arranged traction shaft 8 pulls the traction frame 9 to move back and forth. The operation of the traction frame 9 is synchronized with the rotation of the cam 7, so that filtering and cleaning only need to be controlled by a single driving structure. While ensuring the stability of the operation, it also ensures that the alternating operation between the two processes can be carried out in an orderly manner.

[0028] To sum up, the seedling water pool purification device and method provided in this embodiment, when filtering and purifying the seedling water, firstly add the seedling water to be treated from the discharge pipe 35 into the mixing bin 2, and ensure that the added amount does not overflow the mixing bin 2, and then start the motor 19, and use the motor 19 to drive the cam 7 and the turntable 6 to rotate synchronously at a low speed.

[0029] When the cam 7 rotates, the cam 7 abuts against the roller 18 structure arranged above it, so that the roller 18 can move up and down reciprocatingly. When the roller 18 rises in height, the lifting frame 17 drives the connecting frame 25 to rise in height, and the connecting frame 25 drives the cover plate 26 and the discharge port 24 to separate from each other. At this time, the seedling water in the mixing chamber 2 enters the filter chamber 1 through the discharge port 24. At this time, the return spring 27 structure is compressed. As the cam 7 continues to rotate, the roller 18 structure drops in height, and the return spring 27 makes the cover plate 26 structure drop rapidly, thereby completing the rapid closing of the discharge port 24. At this time, the seedling water will stop entering the filter chamber 1. When the seedling water enters the filter bin 1 through the discharge port 24, the seedling water contacts the guide plate 30 structure, wherein the guide plate 30 has the function of guiding the flow direction of the seedling water. The guided seedling water contacts each other, which further improves the mixing effect of the seedling water. At the same time, it also avoids the discharge of the seedling water from the side port 21, plays a good role in guiding the flow direction of the seedling water. The seedling water is separated by multiple groups of guide plates 30, avoiding the problem of single-position filtration on the filter screen 31, thereby improving the uniformity of seedling water filtration. The inclination angle of the guide plate 30 can be set by rotating the deflection rod 29, so that the structure at this location is adjustable.

[0030] When the turntable 6 rotates, the traction frame 9 can be pulled by the traction shaft 8 on the turntable 6 to move, and the traction frame 9 is used to pull the sliding rod 10 to slide on the L-shaped groove 14. Since the sliding rod 10 and the sliding rod 2 11 are fixedly connected to the cleaning plate 12, when the sliding rod 10 moves, the sliding rod 2 11 also moves synchronously. When the sliding rod 10 moves to the leftmost end, the sliding rod 2 11 slides to the vertical part of the L-shaped groove 14. At this time, the sliding rod 2 11 is set directly above the sliding rod 10. At this time, the cleaning plate 12 is in a vertical state. When the equipment stops, it is necessary to ensure that the cleaning plate 12 is in a vertical state. The operator can manually rotate the turntable 6 structure to make the cleaning plate 12 move to this state, and then clean the bristles with clean water. 32 structure, the cleaning plate 12 in the vertical state can drain the bristles 32 well, and can ensure that the bristles 32 drain water quickly to prevent the seedling water from corroding the bristles 32. In this state, when the sliding rod 10 moves horizontally to the right, the cleaning plate 12 flips to a horizontal state and moves from the side port 21 to the filter bin 1. The bristles 32 can be used to clean the upper surface of the filter screen 31, thereby disturbing the impurities on the filter screen 31 and preventing the impurities from repeatedly accumulating on the filter screen 31. Brushing the filter screen 31 back and forth will also bring out a certain amount of impurities through the bristles 32. The placement plate 15 arranged on one side of the side port 21 can move the bristles 32 for cleaning, so that the impurities and the bristles 32 are separated from each other, which has the effect of cleaning the bristles 32 to a certain extent.

[0031] The seedling water discharge and purification operation and the cleaning of the filter 31 are performed alternately. This operation requires ensuring that the lifting angle range of the cam 7 and the connection position of the traction shaft 8 are independent of each other, that is, after the discharge, filtering and purification are completed, the cleaning plate 12 will enter the filter bin 1 to clean the filter 31. At this time, the seedling water content on the high-efficiency filtered filter 31 is relatively small, and part of the seedling water can quickly pass through the filter 31 to complete the cleaning, and only a certain amount of impurities remains on the filter 31. Therefore, the seedling water content adhering to the bristles 32 after cleaning is very small, and more of the cleaning is the large particles of impurities carried, so that only a small amount of seedling water is brought out when the bristles 32 are removed later.

[0032] The filtered seedling water will be stored in the filter bin 1, and then the impurities retained inside can be cleaned by disassembling the shell 34. When it is necessary to collect the purified seedling water, the seedling water can be taken out from the discharge pipe 5. The seedling water filtering and purification device can ensure the quality of the seedling water and reduce the content of large particle impurities.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
