Description

Technical Field

[0001] This utility model relates to the field of filtration and purification technology, specifically to a filtration and purification device for irrigation water for fruit trees. Background Technology

[0002] Filtration and purification technology is a widely used separation and purification technology in various fields. It aims to remove impurities, pollutants, or harmful substances from mixtures through physical, chemical, or biological methods to obtain a purer target substance or environment.

[0003] Utility model patent CN209759148U discloses a purification device for irrigation water of Paphiopedilum orchids with good filtration effect. The device includes a sand collection tank with a support foot fixedly connected to its bottom and a sand and gravel inlet fixedly connected to its top. A centrifugal shell is sealed to the top of the sand and gravel inlet. The centrifugal shell has a conical structure, and a vortex cover is fixedly and sealed to its top. A water inlet pipe is welded to the right side of the vortex cover, and a main pipe is sealed to the top of the vortex cover via a connecting flange. By using the vortex cover and centrifugal shell, water enters the centrifugal shell through the vortex cover. The rotation generates centrifugal force, pushing sediment and denser solid particles along the pipe wall to form a vortex. This allows sand and stones to enter the sand collection tank, while the purified water flows out along the outlet pipe, achieving water-sand separation and filtering out heavier impurities from the water source to a great extent.

[0004] Although the filtration effect of this orchid irrigation water purification device is good, it still has the following problems in actual use: there is no shut-off valve between the sand collection tank and the centrifuge shell, which makes it easy for mud and sand to be backflushed into the centrifuge shell when cleaning the sand collection tank; moreover, the harmful substance filter is difficult to remove and is prone to accumulation. In view of this, we propose a fruit tree irrigation water filtration and purification device. Utility Model Content

[0005] In view of the aforementioned defects or shortcomings of existing technologies, such as easy backflow of silt and difficulty in cleaning filters, it is desirable to provide a filtration and purification device for irrigation water for fruit trees.

[0006] In a first aspect, this application provides a fruit tree irrigation water filtration and purification device, including an inlet pipe connected to an external water source and an inlet pump installed on the inlet pipe, and a centrifuge cylinder connected to the other end of the inlet pipe. The side wall of the centrifuge cylinder near the top has an inlet for accommodating and fixing the end of the inlet pipe. The top of the centrifuge cylinder is connected to an outlet pipe, and the bottom of the centrifuge cylinder is connected to a sand collection tank. One end of the sand collection tank has a sand discharge port, and the end of the sand collection tank away from the sand discharge port is equipped with a cleaning valve connected to an external water source. The outlet pipe is connected to a filter cylinder through the outlet pump. The filter cylinder has a sedimentation layer, a filter layer and an adsorption layer arranged sequentially from top to bottom. The bottom of the filter cylinder is connected to a flexible hose for irrigating fruit trees.

[0007] According to the technical solution provided in the embodiments of this application, a water-saving valve is installed between the external water source and the water pump in the water inlet pipe;

[0008] In this setup, the water-saving valve is connected to an external water source and provides a certain water pressure. The inlet pump further pressurizes the water, increasing the centrifugal force when the water flows into the centrifuge cylinder, thereby improving the filtration efficiency.

[0009] According to the technical solution provided in the embodiments of this application, the centrifuge cylinder is in the shape of an inverted bucket, the angle between the inclined surface of the inverted bucket side wall of the centrifuge cylinder and the vertical direction is 15°-30°, the water outlet pipe is inserted into the centrifuge cylinder, the height of the end of the water outlet pipe is located at one-third to one-half of the height of the centrifuge cylinder, and a coarse filter screen is provided at the end of the water outlet pipe.

[0010] In this setting, the centrifugal force works best within the range of 15°-30°, effectively separating impurities. Inserting the water outlet pipe to one-third to one-half of its length effectively draws out the filtered water.

[0011] According to the technical solution provided in the embodiments of this application, an anti-surge plate is fixedly installed on the top surface inside the centrifuge body corresponding to the water inlet, and the angle between the horizontal central axis of the water inlet and the extension line of the horizontal center of the anti-surge plate is 30°-45°.

[0012] In this setup, the anti-impact plate itself can prevent water flow from directly impacting the inner wall of the centrifuge cylinder, and the angle between the anti-impact plate and the water inlet can guide the water flow to rotate more smoothly inside the centrifuge cylinder to remove impurities.

[0013] According to the technical solution provided in the embodiments of this application, a water-blocking valve is connected between the bottom end of the centrifuge cylinder and the top end of the sand collection tank, and a cleaning port communicating with the cleaning valve is opened at the end of the sand collection tank away from the sand discharge port.

[0014] In this setup, the water-blocking valve can seal the sand collection tank, while the cleaning valve can control the water flow to more effectively clean the sand collection tank.

[0015] According to the technical solution provided in the embodiments of this application, a pressure valve for venting and depressurizing is installed at the highest point of the pipe section between the centrifuge cylinder and the filter cylinder in the water outlet pipe, and the diameter of the pressure valve is greater than one-quarter of the inner diameter of the water outlet pipe.

[0016] In this setup, the pressure valve can expel air from the centrifuge cylinder before filtration, improving subsequent filtration efficiency. Installing the pressure valve at the highest point of the pipeline can remove any air that may accumulate in the pipeline. Furthermore, the diameter of the pressure valve is greater than one-quarter of the inner diameter of the water pipe to avoid poor venting due to the valve being too small.

[0017] According to the technical solution provided in the embodiments of this application, the top of the filter cylinder is connected to the outlet end flange of the water outlet pipe. The filter cylinder is divided into an upper chamber, a middle chamber, and a lower chamber with diameters decreasing sequentially from top to bottom. The sedimentation layer, the filter layer, and the adsorption layer are all circular stepped structures with outer diameters decreasing sequentially. The inner dimensions of the upper chamber, the middle chamber, and the lower chamber correspond to and are adapted to the outer dimensions of the sedimentation layer, the filter layer, and the adsorption layer, respectively.

[0018] This setup, with its sedimentation layer, filter layer, and adsorption layer, can effectively filter out gravel, organic matter, pigments, odors, and some heavy metal ions from the water. The layered arrangement makes it easy to remove and clean.

[0019] According to the technical solution provided in the embodiments of this application, a feeder for adding flocculant is also fixedly installed on the top of the centrifuge cylinder, and the top of the feeder is provided with a cover that can be opened or sealed.

[0020] In this setting, the flocculant accelerates the sedimentation efficiency of sediment in the water flow, and the openable or sealed cap prevents water from splashing out of the centrifuge tube during filtration.

[0021] According to the technical solution provided in the embodiments of this application, a base is provided below the sand collection tank, and the sand collection tank is installed on the base by a number of legs, the number of which is at least two.

[0022] In this configuration, the legs and base work together to ensure the overall stability of the device during operation.

[0023] In summary, this technical solution specifically discloses a filtration and purification device for fruit tree irrigation water, which includes a centrifugal cylinder, a baffle plate, a sand collection tank, and a filter cylinder. The baffle plate guides the water flow into the centrifugal cylinder for centrifugal rotation. Under the action of centrifugal force, impurities such as sand and gravel settle into the sand collection tank, while the clean water floats up and enters the filter cylinder through the outlet pipe for further multi-stage filtration. Finally, the filtered water is used for irrigation through a flexible hose. Attached Figure Description

[0039] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Please see Figures 1-5 The fruit tree irrigation water filtration and purification device includes an inlet pipe connected to an external water source and an inlet pump 2 installed on the inlet pipe. It also includes a centrifuge cylinder 3 connected to the other end of the inlet pipe. The side wall of the centrifuge cylinder 3 near the top has an inlet port 31 for accommodating and fixing the end of the inlet pipe. The top of the centrifuge cylinder 3 is connected to an outlet pipe 32. The bottom of the centrifuge cylinder 3 is connected to a sand collection tank 4. One end of the sand collection tank 4 is provided with a sand discharge port 41. The end of the sand collection tank 4 away from the sand discharge port 41 is equipped with a cleaning valve 44 connected to an external water source. The outlet pipe 32 is connected to a filter cylinder 5 through an outlet pump 36. The filter cylinder 5 has a sedimentation layer 51, a filter layer 52 and an adsorption layer 53 arranged sequentially from top to bottom. The bottom of the filter cylinder 5 is connected to a flexible hose 6 for irrigating fruit trees.

[0042] In this example, such as Figure 1 As shown, a water-saving valve 1 is installed between the external water source and the water pump 2 in the water inlet pipe. The water-saving valve 1 is connected to the external water source and the water pump 2 to accelerate the flow of water into the centrifuge cylinder 3, thereby increasing the centrifugal force and improving the filtration capacity. The water-saving valve 1 is preferably made of aluminum alloy. Since there may be corrosive impurities in the water flow, the copper alloy water-saving valve 1 can prevent corrosion.

[0043] Furthermore, such as Figure 2 As shown, the centrifuge cylinder 3 is in the shape of an inverted bucket. The angle between the inclined side wall of the inverted bucket and the vertical direction is 15°-30°. The water outlet pipe 32 is inserted into the centrifuge cylinder 3. The height of the end of the water outlet pipe 32 is one-third to one-half of the height inside the centrifuge cylinder 3. A coarse filter screen 37 is provided at the end of the water outlet pipe 32. Within the range of 15°-30°, the centrifugal force of the water flow is most effective, which can more effectively separate impurities from the solid and liquid. The insertion depth of the water outlet pipe 32 helps to draw out the filtered water flow. The coarse filter screen 37 can better filter out impurities in the water.

[0044] Furthermore, such as Figure 2 As shown, an anti-impact plate 33 is fixedly installed on the top surface of the centrifuge cylinder 3 at the corresponding inlet 31. The angle between the horizontal central axis of the inlet 31 and the extended horizontal center line of the anti-impact plate 33 is 30°-45°. Due to the action of the water pump 2, the water flow speed is too fast and it is easy to directly impact the inner wall of the centrifuge cylinder 3, which reduces its durability. The anti-impact plate 33 can prevent the water flow from directly impacting the inner wall of the centrifuge cylinder 3, and the angle between the anti-impact plate 33 and the inlet 31 can guide the water flow to better rotate and filter along the inner wall of the centrifuge cylinder 3.

[0045] In this example, such as Figures 1-2As shown, a water-blocking valve 43 is connected between the bottom end of the centrifuge cylinder 3 and the top end of the sand collection tank 4. The end of the sand collection tank 4 away from the sand discharge port 41 is provided with a cleaning port 42 that communicates with the cleaning valve 44. The water-blocking valve 43 is preferably made of stainless steel to prevent corrosion by the separated impurities, and it also acts as a sealer for the sand collection tank 4 when cleaning it. The cleaning valve 44 can control the water flow to clean the sand collection tank 4 more effectively.

[0046] Furthermore, such as Figure 1 As shown, a pressure valve 34 for venting and depressurizing is installed at the highest point of the section of the water outlet pipe 32 between the centrifuge cylinder 3 and the filter cylinder 5. The diameter of the pressure valve 34 is larger than one-quarter of the inner diameter of the water outlet pipe 32. The pressure valve 34 installed at the highest point of the water pipe can remove air that may accumulate in the pipe, preventing air from entering the filter and affecting its normal operation. It can also prevent cavitation, water hammer and other phenomena caused by air accumulation in the pipe, thus protecting the safety of the pipeline system. In addition, the diameter of the pressure valve 34 is large enough to ensure that the air in the pipeline system is effectively discharged, avoiding poor venting due to the small diameter of the pressure valve 34, which would affect the normal operation of the system.

[0047] It is worth mentioning that, such as Figures 3-4 As shown, the top of the filter cylinder 5 is connected to the outlet flange of the outlet pipe 32. The interior of the filter cylinder 5 is divided into an upper chamber 54, a middle chamber 55, and a lower chamber 56 with decreasing diameters from top to bottom. The sedimentation layer 51, the filter layer 52, and the adsorption layer 53 are all circular stepped structures with decreasing outer diameters. The inner dimensions of the upper chamber 54, the middle chamber 55, and the lower chamber 56 correspond to and are compatible with the outer dimensions of the sedimentation layer 51, the filter layer 52, and the adsorption layer 53, respectively. The sedimentation layer 51, the filter layer 52, and the adsorption layer 53 can further filter out smaller particles, organic matter, pigments, odors, some heavy metal ions, as well as tiny particles and colloids in the water. The upper and lower tiers are placed inside the filter cylinder 5 for easy removal, replacement, and cleaning from top to bottom.

[0048] Furthermore, such as Figures 1-2 As shown, a feeder 35 for adding flocculant is also fixedly installed on the top of the centrifuge cylinder 3. The top of the feeder 35 is provided with a cover that can be opened or sealed. Adding flocculant from the feeder 35 can promote the accelerated coagulation and sedimentation of mud and sand in the water to improve filtration efficiency. The cover that can be opened or sealed can ensure the airtightness of the device and prevent water in the centrifuge cylinder 3 from splashing out during filtration.

[0049] Furthermore, such as Figure 1 As shown, a base 8 is provided below the sand collection tank 4. The sand collection tank 4 is installed on the base 8 by several legs 7. The number of legs 7 is at least two. The two legs 7 installed on the base 8 can ensure the stability of the overall operation of the device.

[0050] Finally, it should be noted that the water-saving valve 1, water inlet pump 2, water-blocking valve 43, cleaning valve 44 and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0051] Working principle: When using the fruit tree irrigation water filtration and purification device in this embodiment, the water-saving valve 1, the water inlet pump 2, the air pressure valve 34 and the water blocking valve 43 are opened to discharge the pressurized water flow to the water inlet 31. After the water flows in from the water inlet 31, it hits the anti-surge plate 33 and is guided to the inner wall of the centrifugal cylinder 3 and begins to rotate. Due to the different densities of sand and water, under the action of centrifugal force, centripetal buoyancy and fluid drag, the denser silt sinks and settles and can be discharged into the sand collection tank 4 by opening the water blocking valve 43. The less dense clean water will carry a certain amount of air and rise into the water outlet pipe 32. Because the density of gas is less than that of water, it will naturally float and accumulate and be discharged from the air pressure valve 34 to prevent the gas from accumulating and causing the air pressure to rise. The clean water continues to enter the filter cylinder 5 through the water outlet pipe 32. It is further filtered by the sedimentation layer 51, the filter layer 52 and the adsorption layer 53 to remove smaller particles, organic matter, pigments, odors, some heavy metal ions, as well as tiny particles and colloids in the water. Finally, it is discharged through the hose 6 for fruit tree irrigation.

[0052] After use, the fruit tree irrigation water filtration and purification device of this embodiment closes the water blocking valve 43, opens the sand discharge port 41 and the cleaning valve 44, and the water flows into the sand collection tank 4, pushing the mud and sand out of the sand discharge port 41.

[0053] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
