Beneficial effects

[0011] This utility model provides a quick-opening horizontal low-resistance filter. It offers the following advantages: By coordinating a pressure gauge, a wastewater valve, and a flushing valve, the pressure gauge reading on the cover plate indicates excessive pressure at the inlet of the filter element inside the mounting housing. At this point, the operator closes the inlet and outlet valves and opens the wastewater and flushing valves. Driven by the pump, cleaning water enters the mounting housing through the flushing valve to clean the filter element. The wastewater is discharged through the wastewater valve. During flushing, the water flow impacts the paddles, causing the filter element to rotate. With the assistance of an auxiliary cleaning device, the inner wall of the filter element is cleaned. This avoids frequent filter element replacements, preventing a shortened lifespan of the filtration system.

[0012] Through the cooperation of the fixing block, the insert rod, and the spring, the insert rod is inserted into the bottom of the fixing block under the action of the spring, preventing the drive rod and the cleaning brush from rotating when the filter element rotates. When you want to manually rotate the drive rod, pull the lever to retract the insert rod into the fixed seat, thus separating the insert rod from the fixing block so that the operator can rotate it.

[0019] 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.

[0020] In actual use, because horizontal filters have a better filtration effect, the filter element needs to be replaced every once in a while. Frequent replacement will increase costs and reduce the lifespan of the filter.

[0021] Therefore, in actual use, because horizontal filters have a better filtration effect, the filter element needs to be replaced every once in a while. Frequent replacement will increase costs and reduce the lifespan of the filter.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-5As can be seen, a quick-opening horizontal low-resistance filter includes a mounting shell 1, a filter element 11 installed inside the mounting shell 1, an inlet valve 12 installed on the top of the mounting shell 1, an outlet valve 13 installed on one side of the mounting shell 1, and a cover plate 14 fixedly connected to the other side of the mounting shell 1. The quick-opening horizontal low-resistance filter also includes a backwashing device 2, a fixing device 3, and a limiting device 4. The backwashing device 2 is installed at the bottom of the mounting shell 1; the fixing device 3 is installed on the outer wall of the cover plate 14; and the limiting device 4 is installed on the outer wall of the filter element 11. The filter element 11 is cleaned by the backwashing device 2, the fixing device 3 ensures the stability of the backwashing device 2 during operation, and the limiting device 4 ensures the stability of the filter element 11 during operation.

[0024] In the specific implementation process, it is worth noting that the models of the inlet valve 12 and outlet valve 13 are not limited, as long as they meet the actual use conditions. This technology is a publicly disclosed technology in this field. A rubber gasket is provided between the cover plate 14 and the mounting shell 1. The cover plate 14 and the mounting shell 1 are fixed together by bolts, which compresses the rubber gasket and ensures the sealing between the cover plate 14 and the mounting shell 1. The material of the filter element 11 is selected according to the filtered substance, as long as it meets the actual use conditions. The inner wall of the mounting shell 1 is provided with a corrosion-resistant layer to protect the mounting shell 1. Under the action of the backwashing device 2, the filter element 11 inside the mounting shell 1 is cleaned to avoid frequent replacement, which would shorten the life of the device. The fixing device 3 can make the backwashing device 2 stable during operation, and the limiting device 4 can ensure the stability of the filter element 11 during operation and protect it.

[0025] Furthermore, the backwashing device 2 includes a pressure gauge 21, a sewage valve 22, a flushing valve 23, a paddle 24, and an auxiliary cleaning device 25. The pressure gauge 21 is fixedly connected to the outer wall of the cover plate 14; the sewage valve 22 is fixedly connected to one side of the bottom of the mounting housing 1; the flushing valve 23 is fixedly connected to the rear side of the bottom of the mounting housing 1 away from the sewage valve 22; the paddle 24 is fixedly connected to the outer wall of the filter element 11; and the auxiliary cleaning device 25 is installed inside the filter element 11. The filter element 11 is cleaned by the sewage valve 22 and the flushing valve 23. The pressure gauge 21 is used to observe the air pressure inside the mounting housing 1 to determine whether cleaning is required. The paddle 24 drives the filter element 11 to rotate, so that the auxiliary cleaning device 25 cleans the inner wall of the filter element 11.

[0026] In the specific implementation process, it is worth noting that an eight-character trumpet-shaped nozzle is installed at the end of the flushing valve 23 that extends into the mounting housing 1, which can instantly pressurize and increase the purging area. A pump body is installed at the end of the flushing valve 23 that extends into the mounting housing 1. During cleaning, the flushing pressure is changed by adjusting the size of the water outlet in the flushing valve 23. Intermittent multiple pressurization technology is used to purge the filter element, so that the filter element 11 is cleaner. The wastewater generated during cleaning is discharged through the wastewater valve 22. Several paddles 24 are set on the outer wall of the filter element 11. When the flushing valve 23 is flushing, the water flow will push the paddles 24 to move, thereby driving the filter element 11 to rotate in the mounting housing 1. In addition, with the auxiliary cleaning device 25, the inside of the filter element 11 is also cleaned, avoiding frequent replacement of the filter element 11.

[0027] Furthermore, the auxiliary cleaning device 25 includes a cleaning brush 251 and a drive rod 252. The cleaning brush 251 is attached to the inner wall of the filter element 11. The drive rod 252 is fixedly connected to the outer wall of the cleaning brush 251, and the side near the cover plate 14 passes through the cover plate 14 through a sealed bearing. The inner wall of the filter element 11 is cleaned by the cooperation of the cleaning brush 251 and the drive rod 252.

[0028] In the specific implementation process, it is worth noting that the surface of the cleaning brush 251 is provided with soft bristles, and with the support of the drive rod 252, it can clean the inner wall of the filter element 11.

[0029] Specifically, when using this quick-opening horizontal low-resistance filter, water enters through the inlet valve 12 during filtration. The water passes through the filter element 11 within the housing 1 and is discharged from the outlet valve 13. When the pressure on the side of the filter element 11 closest to the inlet valve 12 increases, this can be observed by the operator through the pressure gauge 21. The operator then closes both the inlet valve 12 and the outlet valve 13, while opening the wastewater valve 22 and the flushing valve 23. Driven by the pump at the bottom of the flushing valve 23, the wastewater flows through the flushing valve... The nozzle at the top of the filter element 11 sprays water to clean the outer wall of the filter element 11. At the same time, the paddle plate 24 rotates the filter element 11 under the impact of the water flow. While the filter element 11 is rotating, the cleaning brush 251 is pressed against the inner wall of the filter element 11 by the drive rod 252, so that the cleaning brush 251 cleans the inner wall of the filter element 11. The wastewater generated during cleaning is discharged through the wastewater valve 22. This avoids the frequent replacement of the filter element 11, which would reduce the service life of the filtration device.

[0030] Example 2: From Figure 1-5As can be seen, the fixing device 3 includes a fixing block 31, a rod 32, a fixing seat 33, a spring 34, and a pull rod 35. The fixing block 31 is fixedly connected to one side of the drive rod 252 extending to the outside of the cover plate 14; the rod 32 is inserted into the inner wall of the fixing block 31; the fixing seat 33 is fixedly connected to the outer wall of the cover plate 14 and sleeved on the outer wall of the rod 32; the spring 34 is pressed against the fixing seat 33 and the rod 32; the pull rod 35 is fixedly connected to the bottom of the rod 32 and inserted into the inner wall of the spring 34, and its outer wall is movably connected to the inner wall of the fixing seat 33; wherein, through the cooperation of the spring 34 and the fixing seat 33, the rod 32 is inserted into the inner wall of the fixing block 31 to fix the drive rod 252, and the pull rod 35 drives the rod 32 to move;

[0031] In the specific implementation process, it is worth noting that the insertion rod 32 is inserted into the bottom of the fixing block 31 under the action of the spring 34, so as to prevent the drive rod 252 and the cleaning brush 251 from rotating when the filter element 11 rotates. When you want to manually rotate the drive rod 252, pull the pull rod 35 to retract the insertion rod 32 into the fixed seat 33, thus separating the insertion rod 32 from the fixing block 31, so that the operator can rotate it.

[0032] Furthermore, the limiting device 4 includes a baffle 41, a limiting ring 42, a limiting strip 43, and a sealing gasket 44. The baffle 41 is fixedly connected to the inner wall of the mounting housing 1; the limiting ring 42 is rotatably connected to the outer wall of the filter element 11 through a sealing bearing, and is fixedly connected to the inner wall of the mounting housing 1 by bolts; the limiting strip 43 is fixedly connected to the outer wall of the limiting ring 42 and slidably engaged with the inner wall of the mounting housing 1; the sealing gasket 44 is pressed against the baffle 41 and the limiting ring 42; wherein, the sealing gasket 44 is sealed between the limiting ring 42 and the mounting housing 1 by the compression of the sealing gasket 44 by the baffle 41 and the limiting ring 42, and the limiting strip 43 makes the limiting ring 42 convenient to install;

[0033] In the specific implementation process, it is worth noting that when the filter element 11 is replaced due to cleaning damage, the cover plate 14 is removed, the bolts between the limiting ring 42 and the mounting shell 1 are removed, and the filter element 11 and the limiting ring 42 are removed. During installation, the limiting strip 43 on the outer wall of the limiting ring 42 is inserted into the inner wall of the mounting shell 1, and the sealing gasket 44 is squeezed between the baffle 41 and the limiting ring 42. Then, the limiting ring 42 is fixed in the mounting shell 1 with bolts. The sealing gasket 44 can prevent leakage from the gap between the limiting ring 42 and the mounting shell 1.

[0034] Specifically, based on the above embodiments, when the filter element 11 is damaged due to cleaning or the filtration effect is reduced, the cover plate 14 is removed from the mounting shell 1, and the bolts on the limiting ring 42 are removed. The limiting ring 42 and the filter element 11 are taken out of the mounting shell 1 for replacement. After replacement, the limiting strip 43 on the outer wall of the limiting ring 42 is inserted into the inner wall of the mounting shell 1 to stabilize the filter element 11 during installation. The limiting ring 42 and the mounting shell 1 are fixed with bolts. Each time during installation, the sealing gasket 44 is placed between the limiting ring 42 and the baffle 41 to prevent leakage between the limiting ring 42 and the mounting shell 1, which would affect the filtration effect.

[0035] 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.
