Abstract
Description
Technical Field
[0001] This utility model belongs to the field of filter technology, and specifically relates to a rotary squeeze flushing filter. Background Technology
[0002] During the purification process of a filter, such as the filtration of liquids, solid impurities and other filtered substances are easily deposited on the filter surface or even penetrate into the filter material, which seriously affects the filtration effect. Therefore, the filter material usually needs to be cleaned after the filter has been used for a period of time. Sometimes, a backwashing pipe is installed in the filter.
[0003] However, backwashing pipes rely on point jets to flush the filter material, and the range, time, and impact force of the jets are limited. This makes it difficult to thoroughly and effectively clean stubborn stains from cylindrical filters. Furthermore, when the filter is not disassembled in the equipment, some backwash water remains inside the elastic filter body waiting to be filtered out. This part of the backwash water with poor flow is not conducive to promoting backwashing operations. In addition, impurities are easily left in the interlayer of the elastic filter body, making it difficult to effectively flush them out by relying solely on water backwashing. Summary of the Invention
[0004] The purpose of this invention is to provide a rotary squeeze rinsing filter to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary squeeze-washing filter, comprising a filter body, a mounting base disposed below the filter body, a rotary backwashing mechanism disposed inside the filter body, the rotary backwashing mechanism comprising a backwashing rotary spray shell and a drive motor, the backwashing rotary spray shell being rotatably connected to the inner cavity of the filter body, the drive motor being fixed to the inner top wall of the mounting base, a squeezing mechanism disposed on the surface of the backwashing rotary spray shell, the squeezing mechanism comprising a squeezing bracket and an elastic squeezing strip, the squeezing bracket being fixed to the side surface of the backwashing rotary spray shell, and the elastic squeezing strip being fixed to the end of the squeezing bracket away from the backwashing rotary spray shell.
[0006] It should be noted in the solution that the upper end face of the backwashing rotary spray shell is fixed with a liquid inlet head, and the inside of the backwashing rotary spray shell is provided with a liquid inlet.
[0007] It is worth noting that the backwashing rotary spray housing has a hollow water passage cavity inside, and the liquid inlet is connected to the hollow water passage cavity.
[0008] Furthermore, it should be noted that the side surface of the backwashing rotary spray shell is provided with spray holes, which are connected to the hollow water passage cavity of the backwashing rotary spray shell.
[0009] In a preferred embodiment, the output end of the drive motor is fixed at the center of the lower end face of the backwashing rotary spray shell, and the elastic extrusion strip is attached to the inner wall of the filter body.
[0010] In a preferred embodiment, the upper end of the liquid inlet pipe head is provided with a docking bearing for connecting to the water supply pipe, and the upper and lower ends of the filter body are both fixed with reinforcing end plates. The lower reinforcing end plate is fixed to the upper surface of the mounting base, and the mounting base is provided with a waterproof chamber inside.
[0011] Compared with the prior art, the rotary squeeze rinsing filter provided by this utility model has at least the following beneficial effects:
[0012] With the addition of a rotary backwashing mechanism, the rotating backwashing spray shell, which sprays water and rotates, can perform a comprehensive backwashing operation from the inside of the filter body. Furthermore, the stirring structure formed by the rotary backwashing spray shell and the extrusion bracket can rapidly stir the water inside the filter body and improve its fluidity. The high-flowing water carries an impact force to backwash the filter body, which can further enhance the cleaning effect on stubborn impurities.
[0013] Through the designed squeezing mechanism, the elastic squeezing strip can rotate along the inner wall of the filter body to achieve the washing operation in conjunction with the water flow. Furthermore, the squeezing of the elastic squeezing strip with the elastic material of the filter body can promote the loosening of its structure so that residual impurities can be discharged. In addition, the elastic squeezing strip has a buffering deformation force during the washing process. This can adaptively adjust the degree of adhesion between the elastic squeezing strip and the inner wall of the filter body and reduce the risk of damage to the filter body caused by excessive brushing force during the washing process.

[0019] 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 embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0020] Please see Figure 1-4 This utility model provides a rotary squeezing and rinsing filter, including a filter body 1, a mounting base 2 below the filter body 1, a rotary backwashing mechanism inside the filter body 1, the rotary backwashing mechanism including a backwashing rotary spray shell 3 and a drive motor 10, the backwashing rotary spray shell 3 being rotatably connected to the inner cavity of the filter body 1, the drive motor 10 being fixed to the inner top wall of the mounting base 2, a squeezing mechanism being provided on the surface of the backwashing rotary spray shell 3, the squeezing mechanism including a squeezing bracket 4 and an elastic squeezing strip 5, the squeezing bracket 4 being fixed to the side surface of the backwashing rotary spray shell 3, and the elastic squeezing strip 5 being fixed to the end of the squeezing bracket 4 away from the backwashing rotary spray shell 3.
[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the upper end face of the backwashing rotary spray housing 3 is fixed with a liquid inlet head 7, and the interior of the backwashing rotary spray housing 3 is provided with a liquid inlet 8.
[0022] Further as Figure 3 As shown, it is worth noting that the backwashing rotary spray shell 3 has a hollow water passage cavity 13 inside, and the liquid inlet 8 is connected to the hollow water passage cavity 13.
[0023] This solution has the following working process: Before use, the external water supply pipe is fixed to the docking bearing 9 to supply water to the hollow water passage cavity 13 of the backwashing rotary spray shell 3. When cleaning the filter fixed in the equipment, the drive motor 10 is turned on. The drive motor 10 drives the backwashing rotary spray shell 3 to rotate in the inner cavity of the filter body 1. In this way, the backwashing rotary spray shell 3, which is spraying water and rotating, can perform a comprehensive backwashing operation from the inside of the filter body 1. Furthermore, the stirring structure formed by the backwashing rotary spray shell 3 and the extrusion bracket 4 can stir the water inside the filter body 1 at high speed and improve its fluidity. The high-flow water carries the impact force to backwash the filter body 1, which can further enhance the cleaning effect on stubborn impurities.
[0024] As can be seen from the above working process, the backwashing rotary spray shell 3 in the spraying and rotating state can perform a comprehensive backwashing operation from the inside of the filter body 1. The stirring structure formed by the backwashing rotary spray shell 3 and the extrusion bracket 4 can stir the water inside the filter body 1 at high speed and improve its fluidity. The high-flow water carrying the impact force backwashes the filter body 1, which can further enhance the cleaning effect on stubborn impurities.
[0025] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the side surface of the backwashing rotary spray shell 3 is provided with a spray hole 6, which is connected to the hollow water passage cavity 13 of the backwashing rotary spray shell 3.
[0026] Further as Figure 4 As shown, it is worth noting that the output end of the drive motor 10 is fixed at the center of the lower end face of the backwashing rotary spray shell 3, and the elastic extrusion strip 5 is pressed against the inner wall of the filter body 1. During the high-speed rotation of the backwashing rotary spray shell 3, the elastic extrusion strip 5 at one end of the extrusion bracket 4 rotates with it. In this way, the elastic extrusion strip 5 can rotate along the inner wall of the filter body 1 to cooperate with the water flow to achieve the brushing operation. Furthermore, the extrusion strip 5 and the elastic material of the filter body 1 are pressed together to promote the loosening of its structure so that residual impurities can be discharged. In addition, the elastic extrusion strip 5 has a buffering deformation force during the brushing process. This can adaptively adjust the degree of contact between the elastic extrusion strip 5 and the inner wall of the filter body 1 and reduce the risk of damage to the filter body 1 due to excessive brushing force during the brushing process.
[0027] Further as Figure 1 As shown, it is worth noting that the upper end of the liquid inlet pipe head 7 is provided with a docking bearing 9 for connecting the water supply pipe. The upper and lower ends of the filter body 1 are both fixed with reinforcing end plates 11. The lower reinforcing end plate 11 is fixed to the upper end face of the mounting base 2. The interior of the mounting base 2 is provided with a waterproof chamber 12.
[0028] In summary: The rotating backwashing spray housing 3, which sprays water and rotates, can perform a comprehensive backwashing operation from the inside of the filter body 1. The stirring structure formed by the rotating backwashing spray housing 3 and the extrusion bracket 4 can agitate the water inside the filter body 1 at high speed and improve its fluidity. The high-flow water carrying the impact force backwashes the filter body 1, which can further enhance the cleaning effect on stubborn impurities. The elastic extrusion strip 5 can rotate along the inner wall of the filter body 1 to achieve the brushing operation in conjunction with the water flow. The extrusion strip 5 and the elastic material of the filter body 1 can promote the loosening of its structure so that residual impurities can be discharged. In addition, the elastic extrusion strip 5 has a buffering deformation force during the brushing process, which can adaptively adjust the degree of contact between the elastic extrusion strip 5 and the inner wall of the filter body 1 and reduce the risk of damage to the filter body 1 due to excessive brushing force during the brushing process.
