Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a portable sediment filtration device used in integrated water and fertilizer systems. Background Technology

[0002] In the field of agricultural irrigation, fertigation technology has been widely used due to its advantages such as water and fertilizer conservation, and improved crop yield and quality. Since irrigation water is mostly taken from rivers, lakes or wells, the water source contains a certain amount of silt. During fertigation, silt will enter the irrigation pipes and sprinklers with the water flow. After long-term accumulation, silt can easily clog the pipes and sprinklers, affecting irrigation. Therefore, it is necessary to use appropriate silt filtration devices.

[0003] Current sediment filtration devices typically only have a single-channel filtration structure. Over time, the filtration structure becomes clogged with sediment. Cleaning the single-channel filtration structure requires the sediment filtration device to be shut down, which cannot guarantee a continuous supply of irrigation water and reduces the performance of the irrigation system. Utility Model Content

[0004] The purpose of this invention is to provide a portable sediment filtration device for use in integrated water and fertilizer systems. This device is equipped with a freely switchable dual-channel structure to filter sediment in the water source, thereby solving the problems mentioned in the background art.

[0006] Preferably, the partition plate is inclinedly disposed inside the first filter cylinder, and the partition plate divides the interior of the first filter cylinder into upper and lower chambers. The partition plate is an annular plate structure that runs vertically through the filter cylinder. The inner wall of the annular partition plate is fixedly connected to the outer surface of the filter screen. The filter screen is a cylindrical structure that runs vertically through the filter cylinder. The internal space of the filter screen is connected to the upper chamber of the first filter cylinder, and the outer surface of the filter screen is inserted into the lower chamber of the first filter cylinder.

[0007] By adopting the above technical solution, the internal space of the No. 1 filter cartridge can be divided using a partition plate, thereby achieving the interception and filtration of impurities.

[0008] Preferably, a water inlet pipe is provided through one side surface of the first filter cylinder, and a water outlet pipe is provided through the other side surface of the first filter cylinder. The water inlet pipe is connected to the upper chamber of the first filter cylinder, and the water outlet pipe is connected to the lower chamber of the first filter cylinder. The first filter cylinder and the second filter cylinder have the same structure, and the first filter cylinder and the second filter cylinder together constitute a double-channel structure.

[0009] By adopting the above technical solution, the dual-channel structure can achieve simultaneous filtration in both channels, thereby increasing filtration efficiency.

[0010] Preferably, one side of the dual-channel structure is connected to a water inlet bend, which is a C-shaped pipe. The two ends of the water inlet bend are respectively connected to the water inlet pipes on the surfaces of the first and second filter cartridges to form a detachable connection structure. An upstream pipe is provided through the surface of the water inlet bend.

[0011] By adopting the above technical solution, water can be introduced into the device by connecting the inlet bend to the upstream pipeline.

[0012] Preferably, a water outlet bend is provided on the other side of the dual-channel structure. The water outlet bend is a C-shaped pipe.

[0014] Preferably, a first valve is provided at one end of the water inlet bend, the first valve being located at the connection section of the water inlet pipe on the surface of the first filter cartridge, and a third valve is provided at the other end of the water inlet bend, the third valve being located at the connection section of the water inlet pipe on the surface of the second filter cartridge.

[0015] Using the above technical solution, the flow of water into the inlet bend can be controlled by valves No. 1 and No. 3.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the portable sediment filtration device used in this integrated water and fertilizer system:

[0019] 1. This device is equipped with a No. 1 filter cartridge and a No. 2 filter cartridge, each with a partition plate and a filter screen to form a filtration structure. The device is installed upstream of the disc filter. The filter screen intercepts large volumes of silt and other impurities in the water pipe. This initial interception before the disc filter is completed reduces the cleaning frequency of the subsequent disc filter, improves filtration efficiency, ensures stable operation of the integrated water and fertilizer equipment, and enhances irrigation effect.

[0020] 2. This device is equipped with a dual-channel structure consisting of a No. 1 filter cartridge and a No. 2 filter cartridge. The two sides of the dual-channel structure are detachably connected to the inlet bend and the outlet bend, respectively. When the irrigation volume is small, one filter structure can be opened to reduce energy consumption. When there are many impurities in the water source, both filter structures can be opened at the same time to enhance the filtration effect. The detachable connection method facilitates the installation and disassembly of the device. It is suitable for farmers with small-scale integrated water and fertilizer application and can meet the needs of different farmland irrigation scenarios.

[0021] 3. The device has valves installed on the inlet and outlet bends on both sides of the dual-channel structure. The valves can be opened and closed as needed, allowing for flexible selection of the working state of filter cartridge No. 1 and filter cartridge No. 2. This allows filter cartridge No. 1 and filter cartridge No. 2 to be used alternately during maintenance, with one being cleaned and maintained while the other continues to work without interrupting irrigation operations, thus improving the efficiency of the equipment.

[0029] 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.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a portable sediment filtration device for use in water and fertilizer integration, including a first filter cylinder 1, a second filter cylinder 2, a cylinder cover 3, a partition plate 4, a filter screen 5, an inlet pipe 6, an outlet pipe 7, an inlet bend 8, an upstream pipe 9, an outlet bend 10, a downstream pipe 11, a first valve 12, a second valve 13, a third valve 14, and a fourth valve 15.

[0031] A water inlet pipe 6 is installed through one side of the surface of filter cartridge 1, and a water outlet pipe 7 is installed through the other side of the surface of filter cartridge 1. The water inlet pipe 6 communicates with the upper chamber of filter cartridge 1, and the water outlet pipe 7 communicates with the lower chamber of filter cartridge 1. Filter cartridge 1 and filter cartridge 2 have the same structure and together form a double-channel structure. One side of the double-channel structure is connected to a water inlet bend pipe 8, which is a C-shaped pipe. The two ends of the water inlet bend pipe 8 are respectively connected to the water inlet pipe 6 on the surface of filter cartridge 1 and filter cartridge 2 to form a detachable connection structure. An upstream pipe 9 is installed through the surface of the water inlet bend pipe 8. The other side of the double-channel structure is provided with a water outlet bend pipe 10, which is also a C-shaped pipe. The two ends of the outlet bend 10 are respectively connected to the outlet pipes 7 on the surfaces of the first filter cylinder 1 and the second filter cylinder 2 to form a detachable connection structure. A downstream pipe 11 is provided through the surface of the outlet bend 10. A valve 12 is provided at one end of the inlet bend 8, which is located at the connection section of the inlet pipe 6 on the surface of the first filter cylinder 1. A valve 14 is provided at the other end of the inlet bend 8, which is located at the connection section of the inlet pipe 6 on the surface of the second filter cylinder 2. A valve 13 is provided at one end of the outlet bend 10, which is located at the connection section of the outlet pipe 7 on the surface of the first filter cylinder 1. A valve 15 is provided at the other end of the outlet bend 10, which is located at the connection section of the outlet pipe 7 on the surface of the second filter cylinder 2.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, during the use of the device, the upstream pipe 9 is connected to the water source, and the downstream pipe 11 is connected to the inlet of the subsequent disc filter. During irrigation, the water source in the upstream pipe 9 is turned on, and the water enters the device through the upstream pipe 9. The device is adjusted according to actual needs. If the sediment content of the water source is low, valves 12 and 13 can be opened, and valves 14 and 15 can be closed, so that the water flows only through the first filter cartridge 1 for filtration. The water flows into the first filter cartridge 1 through the inlet pipe 6 for filtration. The filtered water flows from the outlet pipe 7 into the outlet bend 10, and is then transported to the disc filter via the downstream pipe 11. Similarly, for the plate filter, opening valves 14 and 15 (number 3) and closing valves 12 and 13 (number 2) allows water to be filtered only through filter cartridge 2 (number 2). When filter cartridges 1 and 2 are filtering individually, the other unused filter cartridge (number 1 or number 2) can be disassembled and cleaned to ensure uninterrupted irrigation water supply during device maintenance. If the water source has a high sediment content, opening valves 12, 13, 14, and 15 simultaneously allows water to pass through both filter cartridges 1 and 2 for dual-stage filtration, further improving filtration efficiency.

[0033] The first filter cylinder 1 is a hollow cylindrical structure with an open upper surface. The second filter cylinder 2 is arranged parallel to one side of the first filter cylinder 1. The upper surfaces of the first filter cylinder 1 and the second filter cylinder 2 are respectively bolted with cylinder covers 3. The first filter cylinder 1 has a filter structure inside. The filter structure filters and intercepts mud and sand through the partition plate 4 and the filter screen 5. The filter structure includes the partition plate 4, which is fixedly installed inside the first filter cylinder 1. The surface of the partition plate 4 is fixedly connected to the filter screen 5. The partition plate 4 is inclined inside the first filter cylinder 1. The partition plate 4 divides the interior of the first filter cylinder 1 into upper and lower chambers. The partition plate 4 is an annular plate structure that runs through the upper and lower parts. The inner wall of the annular partition plate 4 is fixedly connected to the outer surface of the filter screen 5. The filter screen 5 is a cylindrical structure that runs through the upper surface. The internal space of the filter screen 5 is connected to the upper chamber of the first filter cylinder 1. The outer surface of the filter screen 5 is inserted into the lower chamber of the first filter cylinder 1.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, during the water filtration process using filter cartridge 1 or filter cartridge 2, taking filter cartridge 1 as an example, water flows into the upper chamber of filter cartridge 1 through the inlet pipe 6. Under the action of the inclined partition plate 4, the water flows into the interior of the filter screen 5. Impurities such as mud and sand are intercepted by the filter screen 5. The filtered water enters the lower chamber of filter cartridge 1 and flows out from the outlet pipe 7 on the other side, completing the filtration. When it is necessary to clean filter cartridge 1 or filter cartridge 2, the cover 3 is removed to clean and maintain the interior of filter cartridge 1 or filter cartridge 2.

[0035] Working principle: When using this portable sediment filtration device for integrated water and fertilizer application, connect the upstream pipe 9 to the water source and the downstream pipe 11 to the disc filter. The water source enters the device through the upstream pipe 9, and the water flows through the inlet pipe 6 into either the first filter cartridge 1 or the second filter cartridge 2. Under the action of the filter screen 5, sediment is intercepted and filtered. The filtered water flows from the outlet pipe 7 into the outlet bend 10 and is output from the downstream pipe 11. By adjusting the opening and closing states of the first valve 12, the second valve 13, the third valve 14, and the fourth valve 15, the use and cessation of the first filter cartridge 1 and the second filter cartridge 2 can be controlled, ensuring continuous irrigation water supply during device maintenance, improving filtration efficiency, and increasing overall practicality.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
