Description

Technical Field

[0001] This utility model relates to the field of alarm device technology, specifically to a filtration device for improving saline-alkali land. Background Technology

[0002] Saline-alkali land is a type of salt accumulation. Due to the presence of salt and alkali components in the soil, the survival rate of plants grown in such land is low. Therefore, the improvement and utilization of saline-alkali soil is crucial for urban economic development and ecological environment improvement. Current methods for saline-alkali land improvement include irrigation to leach salt, backfilling with topsoil, and planting vegetation. Since plants require water for growth, irrigation and water filtration are particularly important. Given the relative scarcity of freshwater resources in saline-alkali areas, it is necessary to develop a water pipe filtration device that can effectively filter out salt and alkali components during irrigation to reduce the amount of salt entering the saline-alkali land. Technological development is of great significance to my country's food security, sustainable resource utilization, and improvement of the ecological environment. Water conservancy engineering improvement technology is one of the most commonly used saline-alkali land improvement technologies. It utilizes the water-salt movement law of salt coming and going with water to remove salt. However, the saline-alkali water after irrigation and flushing still contains many impurities that cannot be washed away. The saline-alkali water that cannot be washed away has an extremely high salt content, exceeding the standard for irrigation water quality. Therefore, a large amount of saline-alkali land water is discharged directly without treatment. The high concentration of water seriously threatens the safety of groundwater and public water bodies. Therefore, it is necessary to develop an improved filtration device to treat and recycle saline-alkali land water.

[0003] A search revealed a filtration device for improving saline-alkali land, publication number CN215692105U. This device includes two bases and a filter box body. A support frame is mounted on the top of each base, and a mounting plate is mounted on one side of the support frame. A nozzle is fixedly mounted in the middle of the mounting plate. An arc-shaped support is fixedly mounted in the middle of the support frame, and the filter box body is fixedly mounted on the top of the arc-shaped support. An inlet is fixedly mounted at one end of the filter box body. A first filter plate and a second filter plate are respectively mounted on one side of the interior of the filter box body, and a stirring mechanism is fixedly mounted on the other side of the interior of the filter box body. An outlet is fixedly mounted on one side of the front of the filter box body. This utility model allows the filter plates to perform multiple filtrations of the water in saline-alkali land, improving the filtration quality of the saline water. A booster pump compresses and pressurizes the filtered water, and the water is further treated by the nozzle itself, allowing for a longer spray range and irrigation of distant plants, greatly improving irrigation efficiency.

[0004] Because groundwater in saline-alkali land can directly and negatively impact vegetation growth and human absorption, specially designed filtration equipment for saline-alkali land improvement is used to purify the groundwater. However, the existing filtration equipment for saline-alkali land improvement has a relatively concealed and difficult-to-remove filter screen. After filtering large amounts of saline-alkali water for a long time, the filter screen inevitably accumulates a large amount of saline-alkali impurities. The accumulation of these impurities will severely clog the filter screen, resulting in a significant reduction in its filtration effect and efficiency. Since the filter screen is not easy to disassemble for cleaning or replacement, this not only increases the difficulty and cost of maintenance but also seriously affects the continuous and effective operation of the filtration equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a filtration device for improving saline-alkali land, which solves the problem that the filter screen in the existing filtration device for improving saline-alkali land is installed in a relatively hidden position and is not easy to disassemble, which leads to the accumulation of impurities and serious blockage of the filter screen, resulting in a significant reduction in filtration effect and efficiency.

[0006] This utility model solves the above-mentioned technical problems through the following technical solution: This utility model includes:

[0007] The housing of a filtration device for improving saline-alkali land has an inlet fixed on one side and an outlet fixed on the other side. A first slid groove is formed at the top of the housing, and a filtration device is slidably connected inside the first slid groove. A baffle is installed inside the housing, and a connecting pipe is installed inside. A water pump device is installed on the surface of the connecting pipe, and a stirring device is installed inside the housing.

[0008] A fixing component is disposed inside the housing of a filtration device for saline-alkali land improvement. Placement slots are provided on both sides of the first chute. A first slider is slidably connected inside the placement slot. A fixing plate is fixed to one side of the first slider, and the surface of the fixing plate is slidably connected to the inside of the first chute. Two return springs are fixed to one side of the first slider, and the other end of the return springs is fixedly connected to one side of the placement slot. A push block is rotatably connected inside the placement slot, and a hollow column is fixed to the top of the push block. Two circular slots are provided on the top of the housing of the filtration device for saline-alkali land improvement. The interior of the circular slots is slidably connected to the surface of the hollow column. A square block is slidably connected inside the hollow column, and a knob is fixed to the top of the square block.

[0009] Preferably, the top of the housing of the filtration device for improving saline-alkali land has two second sliding grooves, and the bottom of the knob is fixed with a second slider, the surface of the second slider being slidably connected to the inside of the second sliding groove.

[0010] Preferably, a tension spring is fixed to the bottom of the block, and the bottom of the tension spring is fixedly connected to the top of the push block.

[0011] Preferably, a first limiting groove is provided on both sides of the hollow column, and a first limiting block is fixed on both sides of the block, with the surface of the first limiting block slidingly connected to the inside of the first limiting groove.

[0012] Preferably, two second limiting grooves are formed on one side of the placement groove, and two second limiting posts are fixed on one side of the first slider, with the surface of the second limiting posts slidably connected to the inside of the second limiting grooves.

[0013] Preferably, the pusher block has an arc-shaped perimeter.

[0014] Preferably, the outer diameter of the surface of the second slider is adapted to the inner diameter of the interior of the second groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] By rotating the knob, the fixed block at the bottom rotates. When the block rotates, it drives the hollow column to rotate, which in turn drives the fixed push block at the bottom to rotate. When the push block rotates, it releases the pushing force on the first slider, allowing the first slider to return to its initial position under the pull of two return springs. When the first slider returns to its initial position, it pulls the fixed plate on one side back to its initial position, thus releasing the surface of the filter device. Once the surface of the filter device is released, it can be removed from the housing of the saline-alkali land improvement filter. This allows the filter device to be cleaned and replaced promptly after excessive accumulation of salt and alkali impurities. This avoids the filter screen being difficult to disassemble due to its closed installation inside the saline-alkali land improvement filter, which leads to a reduction in filtration efficiency due to the long-term accumulation of salt and alkali impurities.

Detailed Implementation

[0024] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0025] This embodiment provides a technical solution: a filtration device for improving saline-alkali land, such as... Figure 1 - Figure 5 As shown, the device includes a housing 1 for a filtration device used for improving saline-alkali land. An inlet 2 is fixed on one side of the housing 1, and an outlet 3 is fixed on the other side. A first sluice 4 is provided on the top of the housing 1. A filtration device 5 is slidably connected inside the first sluice 4. A baffle 7 is installed inside the housing 1. A connecting pipe 6 is installed inside the housing 1. A water pump device 8 is installed on the surface of the connecting pipe 6. A stirring device 9 is installed inside the housing 1.

[0026] A fixing component 25 is disposed inside the housing 1 of the filtration equipment for saline-alkali land improvement. Placement slots 10 are provided on both sides of the first slide groove 4. A first slider 12 is slidably connected inside the placement slot 10. A fixing plate 11 is fixed to one side of the first slider 12, and the surface of the fixing plate 11 is slidably connected to the inside of the first slide groove 4. Two return springs 13 are fixed to one side of the first slider 12, and the other end of the return springs 13 is fixedly connected to one side of the inside of the placement slot 10. A push block 14 is rotatably connected inside the placement slot 10, and a hollow column 16 is fixed to the top of the push block 14. Two circular slots 15 are provided on the top of the filtration equipment housing 1 for saline-alkali land improvement. The inside of the circular slots 15 is slidably connected to the surface of the hollow column 16. A square block 26 is slidably connected inside the hollow column 16, and a knob 17 is fixed to the top of the square block 26. Rotating knob 17 causes the fixed block 26 at the bottom to rotate. When the block 26 rotates, it causes the hollow column 16 to rotate. When the hollow column 16 rotates, it causes the fixed push block 14 at the bottom to rotate. When the push block 14 rotates, it releases the pushing force of the push block 14 surface on the first slider 12, allowing the first slider 12 to return to its initial position under the pull of the two return springs 13. When the first slider 12 returns to its initial position, it pulls the fixed plate 11 on one side back to its initial position, thus releasing the surface of the filter device 5 from fixation. When the surface of the filter device 5 is released from fixation, the filter device 5 can be removed from the inside of the filter housing 1 for saline-alkali land improvement. This allows the filter device 5 to be cleaned and replaced in a timely manner after excessive accumulation of salt and alkali impurities, avoiding the reduction of filtration effect due to long-term accumulation of salt and alkali impurities.

[0027] like Figure 4 and Figure 5 As shown, the top of the housing 1 of the filtration equipment for saline-alkali land improvement has two second slide grooves 18. The bottom of the knob 17 is fixed with a second slider 19. The surface of the second slider 19 is slidably connected to the inside of the second slide groove 18. When the knob 17 is rotated, the knob 17 drives the push block 14 to rotate, which in turn causes the surface of the push block 14 to push the first slider 12 and the fixing plate 11 to fix the filter device 5 placed inside the housing 1 of the filtration equipment for saline-alkali land improvement. When the filter device 5 is fixed, the push block 14 will not rotate due to shaking because the surface of the second slider 19 is inserted into the inside of the second slide groove 18 to form a fixation.

[0028] like Figure 4 and Figure 5 As shown, a tension spring 20 is fixed to the bottom of the block 26. The bottom of the tension spring 20 is fixedly connected to the top of the push block 14. When the surface of the second slider 19 is inserted into the interior of the second slide groove 18, the tension of the tension spring 20 can make the knob 17 have a continuous downward force, preventing the second slider 19 from shaking and dislodging from the interior of the second slide groove 18.

[0029] like Figure 4 and Figure 5 As shown, the hollow column 16 has a first limiting groove 21 on both sides inside, and the block 26 has a first limiting block 22 fixed on both sides. The surface of the first limiting block 22 is slidably connected to the inside of the first limiting groove 21. When the user moves the downward knob 17 to release or fix the surface of the second slider 19 inside the second slide groove 18, the inside of the first limiting groove 21 has a limiting effect on the surface of the first limiting block 22, so that the knob 17 will not pull the surface of the block 26 out of the hollow column 16 when it moves up and down.

[0030] like Figure 3 and Figure 5 As shown, two second limiting grooves 23 are opened on one side of the placement groove 10, and two second limiting posts 24 are fixed on one side of the first slider 12. The surface of the second limiting post 24 is slidably connected to the inside of the second limiting groove 23. When the user rotates the knob 17 to drive the push block 14 to release or fix the filter device 5, the inside of the second limiting groove 23 has a limiting effect on the surface of the second limiting post 24, so that the first slider 12 will not deviate when it moves.

[0031] like Figure 3 and Figure 5 As shown, the push block 14 has an arc shape around its perimeter. This arc shape makes it easier for the push block 14 to push the first slider 12 when it rotates.

[0032] like Figure 4 and Figure 5 As shown, the outer diameter of the surface of the second slider 19 is matched with the inner diameter of the interior of the second slide groove 18. When the user rotates the knob 17 to drive the push block 14 to push the first slider 12 and the fixing plate 11 to fix the surface of the filter device 5, the matching of the outer diameter of the surface of the second slider 19 with the inner diameter of the interior of the second slide groove 18 ensures that the surface of the second slider 19 will not shift left or right after being inserted into the interior of the second slide groove 18. This prevents the surface of the second slider 19 from wobbling left or right inside the interior of the second slide groove 18, which could lead to the failure of the filter device 5 to be fixed.

[0033] In use, first turn the knob 17 to make the bottom fixed block 26 rotate. When the block 26 rotates, it will drive the hollow column 16 to rotate. When the hollow column 16 rotates, it will drive the bottom fixed push block 14 to rotate. When the push block 14 rotates, it will release the pushing force of the push block 14 surface on the first slider 12, so that the first slider 12 returns to the initial position under the pull of the two return springs 13. When the first slider 12 returns to the initial position, it will pull the fixed plate 11 fixed on one side back to the initial position, so that the surface of the filter device 5 is unfixed. When the surface of the filter device 5 is unfixed, the filter device 5 can be taken out from the inside of the housing 1 of the filter equipment for saline-alkali land improvement, so that the filter device 5 can be cleaned and replaced in time after excessive accumulation of salt and alkali impurities.

[0034] By inserting the surface of the second slider 19 into the interior of the second slide groove 18 to form a fixed shape, the push block 14 will not rotate due to shaking. The tension of the tension spring 20 can give the knob 17 a continuous downward force, preventing the surface of the second slider 19 from detaching from the interior of the second slide groove 18 due to shaking. The interior of the first limiting groove 21 has a limiting effect on the surface of the first limiting block 22, preventing the knob 17 from pulling the surface of the block 26 out of the interior of the hollow column 16 when moving up and down. The interior of the second limiting groove 23 has a limiting effect on the surface of the second limiting column 24, preventing the first slider 12 from deviating when moving. The push block 14 has an arc shape around its perimeter, making it smoother when pushing the first slider 12 when rotating. The outer diameter of the surface of the second slider 19 is matched with the inner diameter of the interior of the second slide groove 18, so that the surface of the second slider 19 will not deviate to the left or right after being inserted into the interior of the second slide groove 18, preventing the surface of the second slider 19 from shaking to the left or right inside the interior of the second slide groove 18, which would cause the filter device 5 to fail to be fixed.

[0035] The above are merely preferred embodiments of this utility model and are illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of this utility model, all of which will fall within the protection scope of this utility model.
