Description

Technical Field

[0001] This utility model relates to the field of drip irrigation emitter technology, and more specifically, to a drip irrigation emitter device with multi-stage filtration. Background Technology

[0002] Drip irrigation devices are a micro-irrigation technology that precisely controls water volume. Through drippers, water is delivered directly to the crop root zone in a slow and continuous manner, significantly reducing ineffective evapotranspiration loss and improving water use efficiency. This device has good terrain adaptability and water-saving and yield-increasing effects, and is widely used in arid and semi-arid regions with scarce water resources.

[0003] When using existing drip irrigation devices, the inlet pipe is usually connected to an external water source (such as a water tank, water pump, or tap water system). The water is filtered and purified by a filter screen to remove impurities. The filtered water is then transported through the main pipe and branch pipes to the drip irrigation tapes or drippers placed in the field. Under the control of the pressure regulating device, the water is dripped at a uniform and constant speed to accurately irrigate the root zone of the crop, thereby achieving the goals of high efficiency in water conservation, saving manpower, and promoting crop growth.

[0004] In practical use, existing technologies, because drip irrigation emitters only use a single filter screen, cannot effectively remove impurities of different particle sizes in the water, which easily leads to dripper clogging and uneven water flow, affecting irrigation efficiency and normal crop growth. Therefore, a drip irrigation emitter device with multi-stage filtration is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a drip irrigation device with multi-stage filtration. It achieves step-by-step purification of irrigation water through a coarse filter, a fine filter, a microbial filter, and an activated carbon filter, effectively removing silt, suspended solids, bacteria, algae, and organic pollutants, significantly improving water cleanliness, preventing dripper clogging, and ensuring stable water flow and uniform irrigation in the drip irrigation system. At the same time, under the impact of water flow, the metal spring and the supporting spring work together to drive the multi-stage filtration components to vibrate up and down on the slide rail, reducing the adhesion and accumulation of impurities on the filter surface.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A drip irrigation emitter device with multi-stage filtration includes an emitter body, a cover plate installed on the outer surface of the emitter body, a multi-stage filtration assembly installed inside the emitter body, and a filter disassembly assembly installed inside the multi-stage filtration assembly. The multi-stage filtration assembly includes a main pipe installed inside the emitter body, connecting blocks installed inside the main pipe, coarse filter screens fixedly connected between the connecting blocks, and fine filter screens installed on the outer surface of the connecting blocks near the lower surface of the coarse filter screen. The filter disassembly assembly includes multiple slide rails installed inside the main pipe, the outer surface of the connecting blocks slidingly connected to the interior of the slide rails, and multiple support springs fixedly connected to the inner cavity of the slide rails.

[0010] Furthermore, the multi-stage filtration assembly includes a microbial filter and an activated carbon filter installed on the lower surface of the fine filter screen. The microbial filter and the activated carbon filter are connected to the outer surface of the connecting block, thus clarifying the upper and lower layer arrangement and connection relationship between the biological filter and the activated carbon filter in the multi-stage filtration assembly.

[0011] Furthermore, the cover plate is internally connected to a water inlet pipe, and one end of the main pipe is connected to a branch pipe. Multiple drippers are fixedly connected to the outer surface of the branch pipe, so that the purified water enters the drippers through the branch pipe and is sprayed out through the drippers.

[0012] Furthermore, the filter disassembly assembly includes multiple metal springs fixedly connected to the outer surfaces of the coarse filter, fine filter, microbial filter, and activated carbon filter. These metal springs provide automatic vibration cleaning capability for the multi-stage filtration assembly, effectively preventing filter clogging.

[0013] Furthermore, one end of the support spring is fixedly connected to a support plate, and the upper surface of the support plate abuts against the bottom of the connecting block so that the multi-stage filter assembly can be placed on the support plate to ensure its stability.

[0014] Furthermore, a pair of mounting plates are symmetrically connected to the outer surface of the drip irrigation emitter body, and the mounting plates have multiple mounting holes inside so that the drip irrigation emitter body can be installed in the desired position.

At the same time, under the impact of water flow, the metal spring and the support spring work together to drive the multi-stage filter components to vibrate up and down on the slide rail, reducing the adhesion and accumulation of impurities on the filter screen surface, thereby improving filtration efficiency.

[0028] Example 1:

[0029] Please see Figures 1-4 A drip irrigation emitter device with multi-stage filtration includes a drip irrigation emitter body 1, a cover plate 105 installed on the outer surface of the drip irrigation emitter body 1, and a multi-stage filtration assembly 2 installed inside the drip irrigation emitter body 1.

[0030] Specifically, the multi-stage filtration assembly 2 includes a main pipe 102 installed inside the drip irrigation emitter body 1. A connecting block 205 is installed inside the main pipe 102. A coarse filter screen 201 is fixedly connected between the connecting blocks 205. A fine filter screen 202 is installed on the outer surface of the connecting blocks 205 near the lower surface of the coarse filter screen 201. The multi-stage filtration assembly 2 includes a microbial filter screen 203 and an activated carbon filter screen 204 installed on the lower surface of the fine filter screen 202. The microbial filter screen 203 and the activated carbon filter screen 204 are connected to the outer surface of the connecting blocks 205. An inlet pipe 101 is connected inside the cover plate 105. A branch pipe 103 is connected to one end of the main pipe 102. Multiple drippers 104 are fixedly connected to the outer surface of the branch pipe 103.

[0031] The multi-stage filtration assembly 2 is internally equipped with a filter disassembly assembly 3. The filter disassembly assembly 3 includes multiple slide rails 301 installed inside the main pipe 102. The outer surface of the connecting block 205 is slidably connected to the inside of the slide rail 301. Multiple support springs 302 are fixedly connected to the inner cavity of the slide rail 301. The filter disassembly assembly 3 includes multiple metal springs 303 fixedly connected to the outer surfaces of the coarse filter screen 201, fine filter screen 202, microbial filter screen 203, and activated carbon filter screen 204. One end of the support spring 302 is fixedly connected to a support plate 306. The upper surface of the support plate 306 abuts against the bottom of the connecting block 205. A pair of mounting plates 304 are symmetrically connected to the outer surface of the drip irrigation water dispenser body 1. Multiple mounting holes 305 are opened inside the mounting plates 304.

[0032] Furthermore, after the water flows in, it passes through the coarse filter 201 to remove large particles such as silt and suspended solids. Then, it passes through the fine filter 202 to further intercept smaller particles, improving the filtration accuracy. Next, the water flows through the microbial filter 203 to effectively inhibit the growth of bacteria and algae in the water. Finally, it passes through the activated carbon filter 204 to adsorb organic matter in the water, achieving deep purification and thus completing the multi-stage filtration process. After use, open the cover 105, and then hold the coarse filter 201 and slide it upwards along the slide rail 301 to quickly disassemble the entire multi-stage filter assembly 2 for cleaning or replacement.

[0033] Working principle: In use, first, the drip irrigation device body 1 is firmly fixed in the required position through the mounting holes 305 of the mounting plate 304. Then, the inlet pipe 101 is connected to the external water source to ensure that the water flows smoothly into the main pipe 102. After entering, the water flows through the coarse filter 201 to remove large particles such as silt and suspended solids. Then, it passes through the fine filter 202 to further intercept smaller particles and improve the filtration accuracy. Next, the water flows through the microbial filter 203 to effectively inhibit the growth of bacteria and algae in the water. Finally, it passes through the activated carbon filter 204 to adsorb organic matter, odors and residual chlorine in the water to achieve deep purification, thus completing a multi-stage filtration process. This ensures that the water quality entering the branch pipe 103 and the dripper 104 is clean and stable, and avoids the dripper 104 from clogging. The purified water flows into the branch pipe 103 and is precisely dripped to the crop roots through multiple drippers 104.

[0034] During this process, when water flows through the coarse filter 201, fine filter 202, microbial filter 203, and activated carbon filter 204, it impacts the metal springs 303 on their surfaces, causing the coarse filter 201, fine filter 202, microbial filter 203, and activated carbon filter 204 to vibrate. At the same time, the slight displacement caused by the water flow impact compresses or stretches the support spring 302. Under the elastic force of the support spring 302, and with the guidance of the slide rail 301, the multi-stage filtration assembly 2 will move up and down reciprocally. This vibration and reciprocating motion can reduce the adhesion and accumulation of impurities on the filter surface, thereby improving filtration efficiency and avoiding problems such as dripper 104 clogging and uneven water flow caused by excessively rapid clogging of a single filter, thus ensuring irrigation stability.

[0035] After use, first disconnect the water inlet pipe 101 from the external water source, open the cover plate 105, and then hold the coarse filter screen 201 and slide it upward along the slide rail 301 to quickly disassemble the entire multi-stage filter assembly 2 for cleaning or replacement, which greatly improves the convenience of maintenance. Conversely, it can be quickly installed.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
