Description

Technical Field

[0001] The utility model belongs to the technical field of farmland irrigation equipment, in particular to a floating water source filter. Background Art

[0002] In the field of agricultural production, drip irrigation and sprinkler irrigation are being widely promoted and applied as efficient water-saving irrigation technologies. However, the irrigation pipe network system, especially the drip irrigation pipe network and sprinkler nozzles, are prone to blockage, which places high demands on the quality of irrigation water sources, so the water source must be effectively filtered and treated.

[0003] In addition to underground well water, common irrigation water sources currently include ponds, reservoirs, rivers, lakes and other types. However, these water sources often contain impurities such as floating moss and water plants. Once such substances enter the irrigation pipes with the water flow, they will not only directly block the pipes, but also greatly increase the filtration pressure of the irrigation equipment, seriously affecting the normal operation and service life of the irrigation system. Therefore, in practical applications, setting a water source filter at the inlet end of the water source pipe is a key measure to ensure the stable operation of the irrigation system, which is of great significance to improving agricultural irrigation efficiency and promoting the process of agricultural modernization. Utility Model Content

[0004] The utility model aims to solve the problems existing in the prior art and provides a floating water source filter, which can flush the inside and outside of the cylindrical filter screen to avoid clogging the filter screen and increasing the pump water resistance. It can be used for filtering water sources in ponds, reservoirs, rivers and lakes.

[0005] The purpose of the utility model is achieved in this way:

[0006] A floating water source filter comprises a main frame, and both sides of the main frame are connected with floating barrels; a central axis is fixedly installed horizontally in the middle of the main frame, and the central axis is formed by connecting a first hollow tube and a second hollow tube; a filter cartridge is rotatably installed on the central axis, and the filter cartridge includes a cylindrical filter screen; a motor for driving the filter cartridge to rotate is installed on the upper part of the main frame; a water inlet is provided on the first hollow tube inside the filter cartridge, and the outer end of the first hollow tube is a water outlet; a submersible pump for supplying water to the second hollow tube is connected to the lower side of the central axis inside the filter cartridge, an inner-net flushing pipe connected to the inner cavity of the second hollow tube for flushing the inner side of the cylindrical filter screen is provided on the upper side of the inside of the filter cartridge, and an outer-net flushing pipe connected to the inner cavity of the second hollow tube through the outer end of the second hollow tube for flushing the outer side of the cylindrical filter screen is provided on the upper side of the outside of the filter cartridge, and a plurality of flushing nozzles are provided on the inner-net flushing pipe and the outer-net flushing pipe.

[0007] Preferably, the discs are connected at both ends of the cylindrical filter, and the filter cylinder is installed on the central axis through the bearings on the discs at both ends. This structural design makes the installation of the filter cylinder more stable, and at the same time facilitates the removal and cleaning of the filter, thereby improving the maintenance convenience of the equipment.

[0008] Preferably, one of the discs is a large toothed disc, and the small gear on the motor output shaft meshes with the large toothed disc to drive the filter cartridge to rotate. This gear transmission method has the advantages of high transmission efficiency, compact structure, strong reliability, etc., and can accurately control the rotation speed of the filter cartridge, so that the filter screen can be more evenly washed during the rotation process, further improving the cleaning effect and avoiding the accumulation of impurities on the filter screen to cause blockage.

[0009] Preferably, a filter frame is provided inside the cylindrical filter, and the filter frame includes a plurality of support rings and annularly distributed connecting rods. The filter frame can effectively enhance the strength and stability of the cylindrical filter, prevent the filter from deforming during water flow impact and filtration, thereby ensuring the stability and durability of the filtration effect.

[0010] Compared with the prior art, the utility model has the following significant advantages:

[0011] 1. Combination of high-efficiency filtration and self-cleaning functions: The filter cylinder is driven to rotate by a motor, and the filter is flushed in all directions using the flushing pipe inside and outside the net connected to the submersible pump. This can promptly remove impurities attached to the inside and outside of the filter, effectively avoiding filter blockage, always maintaining a low pump resistance, ensuring a stable supply of irrigation water and filtration efficiency, greatly reducing the frequency and workload of manual filter cleaning, and improving the degree of automation and production efficiency of agricultural irrigation.

[0012] 2. Adapt to a variety of water source environments: Due to the floating design, with the help of float barrels on both sides, the utility model can stably float on the surface of different types of water sources such as ponds, reservoirs, rivers and lakes, and conveniently take water from the water source for filtration. It is not restricted by the water source terrain and water level changes. It has strong adaptability and flexibility and can meet diverse agricultural irrigation needs.

[0013] 3. Reasonable structural design and convenient maintenance: The structural design of the filter cartridge is easy to disassemble and install, and it is convenient to replace the filter or to inspect the inside of the equipment. The setting of the filter rack enhances the durability of the filter, reduces the risk of filter damage caused by water flow impact, reduces the maintenance cost and use cost of the equipment, and is conducive to its widespread application in agricultural production.

[0014] In summary, the floating water source filter of the utility model has obvious advantages in improving the irrigation water source filtering effect, ensuring the stable operation of the irrigation system and reducing the maintenance cost, and can provide strong technical support for efficient water-saving irrigation in the process of agricultural modernization.

[0022] The working principle and operation steps of the utility model are as follows:

[0023] (1) Installation: After the motor 19 and the submersible pump 8 are connected to a power source and the water outlet 6 is connected to a pumping pipeline, the utility model is placed in a pond, a reservoir, a river or a lake. Under the buoyancy of the two floating barrels, 2 / 3 of the filter cartridge 12 is below the water surface, and 1 / 3 of the filter cartridge 12 is above the water surface;

[0024] (2) Filtration: Water from a pond, reservoir, river or lake passes through the cylindrical filter 13 and enters the filter cartridge 12. The filtered water passes through the water inlet 5, the first hollow tube 4 and the water outlet 6 and is pumped by a remote water pump for farmland irrigation.
