Abstract
Description
Technical Field
[0001] This utility model relates to a filter, and more particularly to a high-pressure PP filter, belonging to the field of filter technology. Background Technology
[0002] High-pressure PP filters are key impurity filtration devices in industrial fluid systems. Their core function is to trap particles, suspended solids, and other impurities in the fluid through PP filter elements, ensuring the stable operation of downstream equipment. Existing high-pressure PP filter cartridge mounting barrels and mounting plates are mostly fixed by top clamping. When replacing the filter element, the clamping parts must be completely removed. Moreover, the filter element mounting barrel is embedded deep in the mounting hole due to long-term pressure, making it difficult to pull out directly. It requires the use of auxiliary tools to remove it, which is inconvenient and easily damages the filter element. In addition, high-pressure fluid directly impacts the filter element from the inlet pipe. The existing structure lacks an effective water flow buffer design, which makes the filter element prone to deformation under instantaneous high-pressure impact, affecting filtration accuracy and filter element lifespan.
[0003] Therefore, it is urgent to improve the high-pressure PP filter to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this invention is to provide a high-pressure PP filter. Through a fixing component, the filter element installation bucket can be quickly switched between a pressed and fixed state and a loose and ejected state. The flat spring at the bottom of the installation sleeve provides an upward elastic force when loosened, which automatically pushes the filter element installation bucket out of the installation hole, making it easy to pull out directly and improving replacement efficiency. The inclined water-blocking plate of the upper cavity disperses the high-pressure water flow through the water-permeable holes, reduces the flow rate and changes the flow direction, reduces the instantaneous impact on the filter element, and extends the service life of the filter element.
[0005] To achieve the above objectives, the main technical solution adopted by this utility model includes: a shell, a mounting plate, and a filter element mounting bucket. The shell is a pressure-resistant cavity. The mounting plate is fixedly connected to the inside of the shell, dividing the inner cavity of the shell into an upper cavity and a lower cavity. The mounting plate has mounting holes on its surface. The filter element mounting bucket is inserted into the mounting holes. The filter element mounting bucket includes a mounting sleeve and a filter screen. A flat spring is fixedly connected to the bottom of the mounting sleeve. A sealing ring is fixedly connected to the bottom of the top stepped surface of the mounting sleeve. The mounting plate has fixing components for fixing the filter element mounting bucket on its surface.
[0006] Preferably, the fixing component includes a clamping knob, a clamping plate, and a limiting plate. The clamping knob is threadedly connected to the mounting plate, the clamping plate is rotatably connected to the clamping knob, and the limiting plate is fixedly connected to the mounting plate. The limiting plate has a first limiting groove and a second limiting groove on its surface.
[0007] Preferably, the upper cavity has an inclined groove on its side, and a water-blocking plate with water-permeable holes is slidably connected in the inclined groove.
[0008] Preferably, the upper cavity is connected to a water inlet pipe and the lower cavity is connected to a water outlet pipe, the axes of the water inlet pipe and the water outlet pipe are collinear, and both the water inlet pipe and the water outlet pipe are connected to mounting flanges.
[0009] Preferably, the filter cartridge installation bucket is used to install PP filter cartridges, and the bottom of the first limiting groove is flush with the surface of the mounting plate.
[0010] Preferably, the top of the housing is equipped with a plurality of clamping assemblies for clamping the top cover. The clamping assembly includes a fixed shaft fixedly connected to the housing, a rotating rod rotatably connected to the fixed shaft, and a rotating handle threadedly engaged with the rotating rod.
[0011] Preferably, the inner sidewall of the mounting sleeve is provided with a stop block, the stop block is used to fix the baffle, and the baffle is used to fix the filter element.
[0012] This utility model has at least the following beneficial effects: 1. The filter cartridge installation bucket can be quickly switched between a clamped and a loosened state by means of a fixing component. The flat spring at the bottom of the installation sleeve provides upward elasticity when loosened, which automatically pushes the filter cartridge installation bucket out of the installation hole, making it easy to pull out directly and improving replacement efficiency. The inclined water-blocking plate of the upper cavity disperses the high-pressure water flow through the water permeable holes, reduces the flow rate and changes the flow direction, reduces the instantaneous impact on the filter cartridge, and extends the service life of the filter cartridge.

[0015] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0016] like Figures 1-7 As shown, the high-pressure PP filter provided in this embodiment includes a housing 1, a mounting plate 2, and a filter element mounting bucket 3. The housing 1 is a pressure-resistant cavity. The mounting plate 2, which is fixedly connected inside, divides the inner cavity of the housing 1 into an upper cavity 4 and a lower cavity 5. The mounting plate 2 has mounting holes 6 on its surface. The filter element mounting bucket 3 is inserted into the mounting holes 6 and includes a mounting sleeve 301 and a filter screen 302. A flat spring 303 fixedly connected to the bottom of the mounting sleeve 301 abuts against the bottom of the mounting hole 6. The sealing ring 7 at the bottom of the top step surface fits against the upper surface of the mounting plate 2 to form a sealing structure. The fixing component 8 on the surface of the mounting plate 2 is used to press the filter element mounting bucket 3. The fixing component 8 includes a pressing knob 801 that is threaded into the mounting plate 2, a pressing plate 802 that is rotatably connected to the pressing knob 801, and a limiting plate 803 fixed to the mounting plate 2. The bottom of the first limiting groove 10 on the surface of the limiting plate 803 is flush with the surface of the mounting plate 2, and the depth of the second limiting groove 11 is greater than that of the first limiting groove 10.
[0017] When in use, after inserting the filter element installation bucket 3 into the installation hole 6, rotate the clamping plate 802 into the first limiting groove 10, and tighten the clamping knob 801 to press the lower surface of the clamping plate 802 against the top step surface of the installation sleeve 301. The high-pressure seal between the installation plate 2 and the filter element installation bucket 3 is achieved through the sealing ring 7. When the filter element needs to be replaced, loosen the clamping knob 801, rotate the clamping plate 802 to the second limiting groove 11, and the flat spring 303 releases its elasticity due to the release of pressure, pushing the filter element installation bucket 3 upward out of the surface of the mounting plate 2. The filter element installation bucket 3 can be directly removed without tools.
[0018] Furthermore, a water-blocking plate 13 with permeable holes is slidably connected in the inclined groove 12 on the side of the upper cavity 4. Its inclination direction is opposite to the water flow direction of the inlet pipe 14. After the high-pressure fluid enters the upper cavity 4 through the inlet pipe 14, it first impacts the water-blocking plate 13, disperses through the permeable holes, and then enters the cavity for filtration, avoiding direct impact on the filter element. The inlet pipe 14 and the outlet pipe 15 are respectively connected to the upper cavity 4 and the lower cavity 5 and are collinear. The mounting flange 16 at the end facilitates quick connection with straight pipes and reduces the need for elbow connections.
[0019] The clamping assembly 15 at the top of the housing 1 includes a fixed shaft, a rotating rod, and a rotating handle. The fixed shaft is fixedly connected to the top of the housing 1. The rotating rod can rotate horizontally around the fixed shaft. When the top cover 19 is placed on the top of the housing 1, the rotating rod is rotated to the edge above the top cover 19, and the rotating handle is screwed on to clamp the top cover 19 through threaded transmission. The top is sealed in conjunction with the sealing ring. Disassembly only requires reverse operation and does not require tools such as wrenches.
[0020] In addition, the stop 17 on the inner side wall of the mounting sleeve 301 is used to engage the baffle 18. The baffle 18 is fixed below the stop 17 by rotation, pressing the filter element into the mounting sleeve 301. When replacing the filter element, simply rotate and remove the baffle 18 to take out the old filter element from the mounting sleeve 301 and install the new filter element.
