[0001] This utility model relates to the field of saline-alkali land drainage technology, and in particular to a saline-alkali land drainage and salt prevention device. Background Technology

[0002] The saline-alkali land drainage and salt prevention device is an engineering equipment specifically designed to address the problems of excessive soil salinity and poor water drainage in saline-alkali land. Its core function is to reduce the accumulation of salt in the soil surface and root zone through scientific drainage, thereby creating a low-salt and suitable soil environment for crop growth.

[0003] Existing drainage and salt prevention devices in some saline-alkali lands are inconvenient for filtering out large particles of impurities in the salty rainwater after soil leaching, which affects the continuation of subsequent desalination work and makes it inconvenient to replace desalination consumables.

[0004] Therefore, a drainage and salt prevention device for saline-alkali land is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a drainage and salt prevention device for saline-alkali land, which can solve the problems of existing drainage and salt prevention devices for some saline-alkali lands, which are inconvenient to filter out large particulate impurities in the salty rainwater after soil leaching, thus affecting the continuation of subsequent desalination work, and also inconvenient to replace desalination consumables.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a saline-alkali land drainage and salt prevention device, comprising a water guide channel, a filter box fixedly connected to the right side of the water guide channel, a filtration mechanism disposed inside the filter box, and a filtration removal mechanism disposed on the inner wall of the water guide channel; the filtration removal mechanism comprises a fixed frame, two limit buttons, two fixing blocks and a filter screen, the filter screen being fixedly connected inside the fixed frame, the bottom of the fixing blocks being fixedly connected to the top of the fixed frame, and the surface of the fixed frame contacting the inner wall of the water guide channel.

The partitions are fixedly connected to the inner wall of the storage frame, the right side of the pull block is fixedly connected to the left side of the storage frame, and the storage frame is movably inserted into the interior of the filter box.

[0011] Preferably, a viewing window is embedded in the top of the filter box, and a drain pipe is fixedly connected to the right side of the filter box.

[0012] Preferably, the right side of the water guide channel is inclined downwards, and a support plate is fixedly connected to the bottom of the water guide channel. The number of support plates is several and they are evenly distributed at the bottom of the water guide channel.

[0013] Preferably, the water guide channel, filter box, storage frame and drain pipe are all made of polytetrafluoroethylene.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application, by setting up a filtration mechanism, achieves efficient filtration of large particulate impurities in saline rainwater and convenient disassembly and assembly through the synergistic action of a fixed frame, limit button, fixed block, and filter screen. The fixed frame provides a stable mounting carrier for the filter screen, with its surface contacting the limit plates on the front and rear sides of the top of the water guide channel and its right side fitting against the left side of the filter box, ensuring precise positioning and preventing displacement, thus ensuring a stable flow of rainwater through the filter screen. The threaded hole on the top of the filter box is threadedly connected to the limit button passing through the fixed block, which can firmly lock the fixed frame and prevent loosening. The pull ring on the top of the fixed frame provides a convenient force point for disassembly, facilitating regular cleaning or maintenance of the filter screen. During operation, the filter screen can effectively intercept large particulate impurities in the rainwater, preventing them from entering the filter box and affecting subsequent desalination, thus solving the problem of inconvenient impurity filtration in existing devices and providing a clean water flow environment for subsequent desalination work.

[0016] 2. This application achieves desalination of saline rainwater and convenient replacement of zeolite by setting up a filtration mechanism. The storage frame is movably inserted into the filter box. The mesh fixed on the inner wall can stably fill the zeolite and prevent the zeolite particles from being lost with the water flow, ensuring the stability of the desalination process. The pull block facilitates quick pulling of the storage frame. With the viewing window on the top of the filter box, the status of the zeolite can be observed in real time, and it can be determined in time whether replacement is needed. When replacing, remove the limit button, pull the fixed frame upward until it is separated from the water guide channel, and the storage frame can be pulled out from the inside of the filter box to replace the new zeolite. The operation is convenient and solves the problem of inconvenient replacement of desalination consumables in existing devices. During operation, the zeolite removes the salt in the rainwater by virtue of its adsorption properties. The treated low-salt water is discharged through the drain pipe on the right side of the filter box and can be recycled for irrigation, helping to reduce soil salt accumulation, improve the saline-alkali land environment, and support the agricultural development and ecological restoration of saline-alkali land.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A drainage and salt-prevention device for saline-alkali land includes a water guide channel 1. A filter box 2 is fixedly connected to the right side of the water guide channel 1. A filtration mechanism 5 is provided inside the filter box 2. A filtration removal mechanism 6 is provided on the inner wall of the water guide channel 1. The filtration removal mechanism 6 includes a fixed frame 601, two limit buttons 602, two fixing blocks 603, and a filter screen 604. The filter screen 604 is fixedly connected inside the fixed frame 601. The bottom of the fixing block 603 is fixedly connected to the top of the fixed frame 601. The surface of the fixed frame 601 is in contact with the inner wall of the water guide channel 1.

[0026] In this embodiment: First, the limiting button 602 is removed, and the fixing frame 601 is separated from the water guide trough 1 by the pull ring 7. Then, the storage frame 501 in the filter box 2 is taken out by pulling the pull block 503, filled with zeolite with salt absorption properties, and then reinstalled. By introducing the saline rainwater after soil leaching into the water guide trough 1, the rainwater first passes through the filter screen 604 of the filtration mechanism 6 to remove large particles of impurities, and then enters the filter box 2 to contact the zeolite. The zeolite absorbs salt, and the mesh 502 prevents the zeolite from being lost. The treated rainwater is discharged from the drain pipe 3. Recyclable irrigation allows for observation of the zeolite's condition through the viewing window 4 on the top of the filter box 2. If the color darkens or impurities adhere, it needs to be replaced. The storage box 501 can be pulled out by removing the limit button 602 and the fixing frame 601 to replace the internal zeolite, reducing soil salt accumulation, improving the saline-alkali land environment, and assisting in agricultural development and ecological restoration. This solves the problem that some existing drainage and salt prevention devices for saline-alkali land are inconvenient to filter out large particles of impurities in the salty rainwater after soil leaching, which affects the continuation of subsequent desalination work and makes it inconvenient to replace desalination consumables.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, limiting plates 8 are fixedly connected to the front and rear sides of the top of the water guide channel 1. The surface of the fixing frame 601 is in contact with the surface of the limiting plate 8, and the right side of the fixing frame 601 is in contact with the left side of the filter box 2.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, threaded holes 9 are provided on the front and rear sides of the top of the filter box 2. The bottom of the limit button 602 passes through the fixing block 603 and is connected to the internal thread of the threaded hole 9.

[0029] Specifically, such as Figure 3 As shown, a pull ring 7 is fixedly connected to the top of the fixed frame 601.

[0030] In this embodiment: the limiting plates 8 on the front and rear sides of the top of the water guide channel 1 are in contact with the surface of the fixing frame 601, and the right side of the fixing frame 601 is in contact with the left side of the filter box 2. This can accurately limit the position of the fixing frame 601 in the water guide channel 1 and prevent it from shifting and affecting filtration. The threaded holes 9 on the front and rear sides of the top of the filter box 2 are threadedly connected to the limiting button 602 passing through the fixing block 603, which can securely lock the fixing frame 601 and prevent the fixing frame 601 from loosening. The pull ring 7 on the top of the fixing frame 601 provides a convenient force point for the disassembly and installation of the fixing frame 601, improving operating efficiency.

[0031] Specifically, such as Figure 5 As shown, the filter mechanism 5 includes a storage frame 501, two partitions 502 and a pull block 503. The partitions 502 are fixedly connected to the inner wall of the storage frame 501, and the right side of the pull block 503 is fixedly connected to the left side of the storage frame 501. The storage frame 501 is movably inserted into the inside of the filter box 2.

[0032] Specifically, such as Figure 2 As shown, a viewing window 4 is embedded in the top of the filter box 2, and a drain pipe 3 is fixedly connected to the right side of the filter box 2.

[0033] In this embodiment: In the filtration mechanism 5, the storage frame 501 is movably inserted into the filter box 2, and with the partition 502 fixed on its inner wall, it can not only stably fill zeolite to achieve desalination, but also prevent zeolite from being lost with the water flow through the partition 502, thus ensuring stable desalination. The pull block 503 makes it easy to quickly pull out the storage frame 501 to replace the zeolite. The viewing window 4 on the top of the filter box 2 makes it easy to observe the zeolite usage status in real time. The drain pipe 3 fixedly connected on the right side can discharge the treated low-salt rainwater in a timely manner, ensuring the continuous operation of the entire device.

[0034] Specifically, such as Figure 5 As shown, the right side of the water guide channel 1 is inclined downwards, and a support plate 10 is fixedly connected to the bottom of the water guide channel 1. There are several support plates 10, which are evenly distributed at the bottom of the water guide channel 1.

[0035] Specifically, such as Figure 1 As shown, the water guide trough 1, filter box 2, storage frame 501 and drain pipe 3 are all made of polytetrafluoroethylene.

[0036] In this embodiment, the water guide trough 1 is inclined downward on the right side, which can guide the saline rainwater after rinsing the soil to flow naturally by gravity without the need for additional power, thus saving energy. Several support plates 10 evenly distributed at the bottom can stably support the water guide trough 1, preventing it from deforming due to uneven force and ensuring a stable drainage path. The water guide trough 1, filter box 2, storage frame 501 and drainage pipe 3 are made of polytetrafluoroethylene, which has excellent corrosion resistance and can resist the erosion of saline-alkali environment, greatly extending its service life.

[0037] Working Principle: First, since the water guide trough 1, filter box 2, storage frame 501, and drain pipe 3 are all made of polytetrafluoroethylene (PTFE), this material has excellent corrosion resistance and can work stably in complex and harsh saline-alkali environments, ensuring the long-term performance of the device. During installation, several support plates 10 evenly distributed at the bottom of the water guide trough 1 are placed securely to ensure the stability of the water guide trough 1. Its right side is tilted downwards to allow gravity to naturally guide the water flow. The filter screen 604 is fixed inside the fixed frame 601, and the bottom of the fixing block 603 is connected to the top of the fixed frame 601. The surface of the fixed frame 601 is in contact with the inner wall of the water guide trough 1. The limiting plates 8 fixed on the front and rear sides of the top of the water guide trough 1 can limit the position of the fixed frame 601, ensuring the accuracy of its installation position. Meanwhile, the right side of the fixing frame 601 contacts the left side of the filter box 2. Threaded holes 9 are provided on the front and rear sides of the top of the filter box 2. The bottom of the limit button 602 passes through the fixing block 603 and is threaded into the threaded holes 9 to further fix the fixing frame 601. In addition, the top of the fixing frame 601 is also provided with a pull ring 7 for easy disassembly. Before formal use, first remove the limit button 602, then pull the fixing frame 601 upwards using the pull ring 7 to separate it from the water guide trough 1. Then pull the pull block 503 to pull the storage frame 501 out of the filter box 2. Then fill the storage frame 501 with the external zeolite. Zeolite has the property of adsorbing salt and can effectively remove salt from rainwater. After filling, reset and install the storage frame 501 and the fixing frame 601. When the device is put into operation, the saline rainwater that has washed the soil is introduced into the water guide trough 1. Because the right side of the water guide trough 1 is inclined downwards, the saline rainwater first flows through the filtration mechanism 6 under the action of gravity. The filter screen 604 effectively filters large particles of impurities in the rainwater, preventing these impurities from entering the filter box 2 and affecting the normal operation of the desalination process. The rainwater, initially filtered by the filter screen 604, then enters the filter box 2 and comes into contact with the zeolite in the storage frame 501. At this time, the zeolite plays an adsorption role, removing the salt from the rainwater. The partition screen 502 prevents the zeolite particles from being lost with the water flow, ensuring the stable operation of the desalination process. The water after filtration and desalination is finally discharged from the drain pipe 3 fixedly connected to the right side of the filter box 2. It can be collected for subsequent irrigation and other uses. During the process, the usage of zeolite in the storage frame 501 can be observed through the viewing window 4 embedded in the top of the filter box 2. As time goes by, if the zeolite becomes darker in color or has more impurities attached to its surface, it indicates that the zeolite is close to saturation and needs to be replaced in time. To replace it, remove the limit button 602 again, remove the fixing frame 601, and the storage frame 501 can be pulled out from inside the filter box 2 to replace the zeolite inside. The operation is convenient. By filtering and desalinizing the saline rainwater after soil leaching, the accumulation of salt in the soil is reduced, which is of great significance for improving the soil environment of saline-alkali land. Long-term use can gradually reduce soil salinity, improve land usability, create favorable conditions for crop growth, and help promote agricultural development and ecological restoration of saline-alkali land.This method achieves salt prevention in saline-alkali land, solving the problem that existing drainage and salt prevention devices in some saline-alkali lands are inconvenient for filtering large particles of impurities in saline rainwater after soil leaching, which affects the continuation of subsequent desalination work, and also makes it inconvenient to replace desalination consumables.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
