Description

Technical Field

[0001] This utility model belongs to the field of filtration technology, and in particular relates to a vertical filter with an in-pump tilt angle. Background Technology

[0002] In modern agricultural surface water irrigation, the presence of impurities such as mud, sand, grass, aquatic organisms, and algae in the water often necessitates the installation of sand, centrifugal, disc, or vertical / horizontal backwash filters after the pump. While purifying the water, this process also results in significant pipeline pressure loss, reduced head, increased pump energy consumption, and a shortened pump lifespan. Furthermore, the filtration precision often fails to meet the demands of current low-flow irrigation. Due to these challenges, pre-pump filtration technology has gained popularity among agricultural producers in recent years. The application of pre-pump horizontal and vertical filters significantly reduces head loss after the pump, improves pipeline pressure stability, and enhances water quality accuracy. However, some new problems have also emerged. In horizontal filters before the pump, the filter cartridge is horizontally positioned at the upper level of the water body. The cartridge submerged below the water surface filters the water, while the cartridge above the water surface uses pressurized water to wash away impurities adhering to the filter screen. The rotating cartridge continuously filters the water. The water intake pipe of the horizontal filter is located at the center of the filter, and water is drawn from the circumference of the cartridge, which can easily create negative pressure, affecting the pump's suction head. The larger the pump flow rate and the longer and larger the diameter of the filter cartridge, the greater the impact on the pump's suction head. In vertical filters before the pump, because the filter cartridge is partially submerged below the water surface, the cartridge needs sufficient rigidity to withstand the deformation caused by negative pressure. Therefore, vertical filters before the pump use wedge-shaped mesh, resulting in limited water filtration accuracy, and the higher the required filtration accuracy, the greater the head loss. Utility Model Content

[0003] The purpose of this utility model is to provide a vertical in-pump filter with an upward angle, which solves the technical problem of excessive water intake energy loss in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A vertical filter with an in-pump tilt angle, characterized in that it includes: a frame, the frame having a frame structure, floating plates arranged on both sides of the upper length direction of the frame, a filter cartridge arranged inside the frame, and the filter cartridge's main shaft being inclined to the horizontal plane.

[0005] This utility model discloses a vertical filter with an upward angle before a pump. The filter cartridge has a cylindrical surface and a concave filter end plate, and a portion of the concave filter end plate is immersed in water.

[0006] This utility model discloses a vertical filter with a pump inclination angle, wherein the bottom of the filter cartridge has a downwardly extending water intake chamber, the water intake chamber has a main shaft water intake pipe, the main shaft water intake pipe has several water intake ports, and the upper part of the main shaft water intake pipe is fixedly connected to the main shaft of the filter cartridge.

[0007] The present invention relates to a vertical filter with an inverted angle before a pump, wherein the bottom of the filter cartridge has several axial blades on the surface corresponding to the water intake chamber.

[0008] The present invention relates to a vertical filter with an in-pump tilt angle, wherein a dynamic sealing structure is provided at the junction of the water intake chamber and the main shaft water intake pipe.

[0009] The present invention relates to a vertical filter with an inverted angle before a pump, wherein the water intake chamber has several radial blades on its inner side.

[0010] The beneficial effects of this utility model are as follows: It proposes a vertical filter with an inclination angle before the pump. By setting the filter cylinder at an inclination, the water flow can converge towards the water intake chamber under the action of gravity, thereby reducing the water intake resistance at the water intake port of the main shaft water intake pipe. By setting a concave filter end plate at the top of the filter cylinder, and the inner concave surface is tapered, the water permeability area can be increased after tilting the installation. It also makes the axis of the water inlet hole in the water surface part more vertical, which further improves the water permeability and reduces the filtration resistance.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] like Figure 1-7 As shown, a vertically oriented filter with a pump front tilt angle includes: a frame 200, the frame 200 having a frame structure, floats 300 arranged on both sides of the upper length direction of the frame 200, a filter cartridge 100 arranged inside the frame 200, and the filter cartridge main shaft 110 of the filter cartridge 100 being inclined to the horizontal plane.

[0015] It should be noted that the structure of the frame 200 and float 300 in this application can be the same as that of the prior art, as long as the filter cartridge can be suspended in the water. The internal backwashing component 111 can also be set to clean the part of the filter cartridge that is exposed above the water surface. It is also connected to the backwashing water source through the backwashing water channel interface 112. The main difference is the form of filter cartridge installation, that is, it is not parallel to the horizontal plane and has a certain angle. Of course, to adapt, a support structure needs to be set at the corresponding position on the frame 200 and fixedly connected. A bearing is set at the connection between the filter cartridge 100 and the filter cartridge main shaft 110, which can be an angular bearing or a thrust bearing, etc.

[0016] In a preferred embodiment of this utility model, the filter cartridge 100 has a filter cartridge cylindrical surface 120 and a concave filter end plate 121. A portion of the concave filter end plate 121 is immersed in water. This structure can not only increase the water permeability area, but also minimize the water permeability resistance of the water permeable part. In this way, the part exposed above the water surface during rotation can be backwashed, while the part immersed in the water can be permeated.

[0017] In a preferred embodiment of the present invention, the filter cartridge 100 has a downwardly extending water intake chamber 150 at its bottom, the water intake chamber 150 has a main shaft water intake pipe 130, the main shaft water intake pipe 130 has a plurality of water intake ports 131, and the upper part of the main shaft water intake pipe 130 is fixedly connected to the filter cartridge main shaft 110.

[0018] It should be noted that the main shaft water intake pipe 130 is connected to the water intake pump through the water pump connection port 160, and the upper part of the filter cartridge main shaft 110 is fixedly connected to the frame 200. After the lower part of the filter cartridge main shaft 110 is fixedly connected to the main shaft water intake pipe 130, the main shaft water intake pipe 130 is fixedly connected to the frame 200 to achieve support.

[0019] In a preferred embodiment of the present invention, the bottom surface of the filter cartridge 100 at the corresponding position of the water intake chamber 150 has a plurality of axial blades 140.

[0020] In a preferred embodiment of this utility model, a dynamic sealing structure is provided at the junction of the water intake chamber 150 and the main shaft water intake pipe 130.

[0021] In a preferred embodiment of this utility model, the water intake chamber 150 has a plurality of radial blades 151 on its inner side.

[0022] It should be noted that the axial blade 140 and radial blade 151 are configured in the same way as in the prior art. They interact with the water flow at the water inlet to provide power for the rotation of the filter cartridge 100, thereby facilitating the cleaning of the filter cartridge. The axial blade 140 and radial blade 151 can be used simultaneously or individually depending on the driving force requirements.

[0023] Application examples: such as Figure 6-7 As shown, the water intake pipe of the water intake pump is connected to the water pump connection port 160, and the entire filter is placed in the target water area. The flushing pipe is connected to the water outlet pipe of the water intake pump and connected to the backwash water interface 112 to provide high-pressure water flow. The suction force generated by the water intake pump acts on the axial and radial blades, causing the filter cartridge 100 to rotate. A part of the filter cartridge 100 is exposed above the water surface. Under the action of the backwash assembly 111, the exposed water surface flushes the filter screen of the filter cartridge 100, and the flushing direction is opposite to the direction of the filtered water flow, which can prevent the filter screen from being blocked. Furthermore, due to the setting of the float plate 300, the entire filter can adjust its depth position in the water source according to the change of liquid level.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
