Description

Technical Field

[0001] This utility model relates to the field of microporous filtration technology, specifically a microporous filter. Background Technology

[0002] A microporous filter is a device used for the precise filtration of liquids or gases. Its core filter medium has a uniform microporous structure (the pore size is usually between 0.01 and 10 micrometers), which can intercept tiny particles, bacteria or other impurities, and achieve high-precision separation and purification.

[0003] Existing microporous filters (such as) Figure 1 and Figure 2 As shown, the filter element inside the microporous filter is fixed to the inside of the filter by bolts, while the top cover of the microporous filter is also fixed to the outer shell by multiple bolts. The liquid to be filtered enters the sealed cover through the inlet pipe, is filtered by the filter element, enters the interior of the filter element, and is discharged from the outlet pipe connected to the bottom of the filter element. The filter element is a consumable. The filter element is fixed to the inside of the outer shell by bolts. When replacing it, the bolts need to be removed and replaced. At the same time, the top cover is also fixed by multiple bolts. Disassembly and reinstallation consume a lot of time, which increases the downtime when replacing the filter element and reduces the operating efficiency of the microporous filter. Utility Model Content

[0004] The purpose of this utility model is to provide a microporous filter to solve the problem mentioned in the background art where the filter element is fixed inside the housing by bolts, and replacement requires disassembling the bolts. At the same time, the top cover is also fixed by multiple bolts, and disassembly and reinstallation consume a lot of time. This makes the disassembly and installation process time-consuming when replacing the filter element, increases downtime, and thus reduces the operating efficiency of the microporous filter.

[0005] To solve the above problems, this utility model provides the following technical solution: a microporous filter, comprising a shell, a sealing part, and a filter element:

[0006] The housing has an inlet pipe on its side and an outlet pipe at its bottom. An installation pipe is vertically installed inside the housing, with its bottom connected to the outlet pipe. A sealing part is located at the top of the housing, and includes a sealing cap. A threaded rod is located at the top of the sealing cap, and the threaded rod is threadedly nested with the sealing cap. A rotating frame is rotatably nested at the top of the threaded rod, and a locking rod is located on the side of the rotating frame. Rotation of the threaded rod causes the rotating frame and locking rod to rise, and the locking rod engages with the housing to fix the position of the sealing cap. The filter element is slidably nested outside the installation pipe, with its top abutting against the sealing part.

[0007] By adopting the above technical solution, liquid can enter the housing from the inlet pipe, flow through the filter element for filtration, and the filtered liquid can enter the outlet pipe through the hole on the side of the mounting pipe for discharge. At the same time, the sealing part can be quickly opened and locked by the cooperation of the threaded rod and the locking rod, which facilitates the replacement and maintenance of the filter element.

[0008] Preferably, the housing also has a discharge pipe disposed on the side of the housing, and the side of the installation pipe has several holes that are connected to the liquid outlet pipe.

[0009] By adopting the above technical solution, when cleaning or discharging residual liquid is required, impurities or waste liquid inside the outer casing can be discharged through the discharge pipe, thereby improving the cleanliness and service life of the filter.

[0010] Preferably, a sealing ring is embedded around the top opening of the housing, and the sealing ring abuts against the bottom of the sealing cover.

[0011] By adopting the above technical solution, the sealing performance between the outer shell and the sealing cap can be enhanced, liquid leakage can be prevented, and the stability of the filtration process can be ensured.

[0012] Preferably, there are four locking rods, which are arranged in a rotationally symmetrical structure around the center of the rotating frame. The side of the outer shell has four slots, and the locking rods are embedded in the slots and engaged with the outer shell.

[0013] By adopting the above technical solution, the sealing cover can be evenly tightened by the four locking rods cooperating with the slots on the outer shell, avoiding uneven force on one side that could lead to poor sealing or structural deformation.

[0014] Preferably, the sides of the lever and the bottom of the slot are provided with chamfered structures.

[0015] By adopting the above technical solution, the locking lever can be slid into the locking slot more easily, reducing jamming.

[0016] Preferably, the sealing part also has a threaded groove formed on the top of the sealing cover, the bottom of the threaded rod is nested and threadedly connected to the threaded groove, and the top of the threaded rod is provided with a handle.

[0017] By adopting the above technical solution, the threaded rod can be moved up and down by rotating the handle, thereby controlling the lifting and lowering of the rotating frame and the locking rod, and realizing the rapid opening and locking of the sealing cover.

[0018] Preferably, the sealing part also has a groove formed at the bottom of the sealing cover, a rubber sleeve is embedded inside the groove, a limiting sleeve is embedded at the bottom of the rubber sleeve, the rubber sleeve is located between the limiting sleeve and the sealing cover, and the top of the filter element is embedded in the bottom of the limiting sleeve and abuts against the limiting sleeve.

[0019] By adopting the above technical solution, the device can fix the sealing cover to the top of the housing while fixing the position of the filter element inside the housing through the limiting sleeve, simplifying the installation process. At the same time, the elastic deformation capacity of the rubber sleeve and the limiting sleeve can provide a certain buffering and sealing effect for the filter element during installation, while ensuring the installation stability of the filter element.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: by providing a sealing part, liquid can enter the outer shell from the inlet pipe, flow through the filter element for filtration, and the filtered liquid can enter the outlet pipe through the hole on the side of the installation pipe for discharge. At the same time, the sealing part can be quickly opened and locked by the cooperation of the threaded rod and the locking rod, which facilitates the replacement and maintenance of the filter element. The device can fix the sealing cover on the top of the outer shell while fixing the position of the filter element inside the outer shell by the limiting sleeve, which simplifies the installation process and improves the efficiency of replacing the filter element.

Detailed Implementation

[0030] 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.

[0031] Example 1

[0032] Please see Figure 3 , Figure 4 and Figure 5 This embodiment provides a technical solution: a microporous filter, including a housing 1, a sealing part 2, and a filter element 3.

[0033] The outer casing 1 has an inlet pipe 101 on its side and an outlet pipe 104 at its bottom. An installation pipe 103 is vertically installed inside the outer casing 1, with its bottom connected to the outlet pipe 104. A sealing part 2 is located at the top of the outer casing 1 and has a sealing cover 201. A threaded rod 204 is located at the top of the sealing cover 201, and the threaded rod 204 is threadedly nested with the sealing cover 201. A rotating frame 206 is rotatably nested at the top of the threaded rod 204, and a locking rod 207 is located on the side of the rotating frame 206. The rotation of the threaded rod 204 drives the rotating frame 206 and the locking rod 207 to rise. The locking rod 207 engages with the outer shell 1 to fix the position of the sealing cover 201. The filter element 3 is slidably nested on the outside of the mounting tube 103. The top of the filter element 3 abuts against the sealing part 2, which allows liquid to enter the outer shell 1 from the inlet pipe 101, flow through the filter element 3 for filtration, and the filtered liquid enters the outlet pipe 104 through the hole on the side of the mounting tube 103 for discharge. At the same time, the sealing part 2 can be quickly opened and locked by the cooperation of the threaded rod 204 and the locking rod 207, which facilitates the replacement and maintenance of the filter element 3.

[0034] Example 2

[0035] Please see Figure 6 , Figure 7 and Figure 8 This embodiment provides a technical solution: a microporous filter, including a housing 1 and a sealing part 2.

[0036] A discharge pipe 102 is provided on the side of the housing 1. Several holes are opened on the side of the mounting pipe 103 and are connected to the liquid outlet pipe 104. When cleaning or discharge of residual liquid is required, impurities or waste liquid in the housing 1 can be discharged through the discharge pipe 102, thereby improving the cleanliness and service life of the filter.

[0037] A sealing ring 106 is embedded around the top opening of the outer casing 1. The sealing ring 106 abuts against the bottom of the sealing cover 201, which can enhance the sealing between the outer casing 1 and the sealing cover 201, prevent liquid leakage, and ensure the stability of the filtration process.

[0038] Four locking rods 207 are provided, and the four locking rods 207 are arranged in a rotationally symmetrical structure around the center of the rotating frame 206. Four slots 105 are provided on the side of the outer shell 1. The locking rods 207 are embedded in the slots 105 and are engaged with the outer shell 1. The four locking rods 207 can cooperate with the slots 105 on the outer shell 1 to achieve uniform force and locking of the sealing cover 201, avoiding uneven force on one side that may lead to poor sealing or structural deformation.

[0039] Both the side of the lever 207 and the bottom of the slot 105 are chamfered, which makes it easier for the lever 207 to slide into the slot 105 and reduces jamming.

[0040] A threaded groove 202 is provided on the top of the sealing cover 201. The bottom of the threaded rod 204 is nested and threadedly connected to the threaded groove 202. A handle 205 is provided on the top of the threaded rod 204. The threaded rod 204 can be moved up and down by rotating the handle 205, thereby controlling the lifting and lowering of the rotating frame 206 and the locking rod 207, so as to realize the quick opening and locking of the sealing cover 201.

[0041] A groove 203 is provided at the bottom of the sealing cover 201. A rubber sleeve 208 is embedded inside the groove 203. A limiting sleeve 209 is embedded at the bottom of the rubber sleeve 208. The rubber sleeve 208 is located between the limiting sleeve 209 and the sealing cover 201. The top of the filter element 3 is embedded in the bottom of the limiting sleeve 209 and abuts against the limiting sleeve 209. This allows the device to fix the sealing cover 201 to the top of the outer shell 1 while fixing the position of the filter element 3 inside the outer shell 1 through the limiting sleeve 209, simplifying the installation process. At the same time, the elastic deformation ability of the rubber sleeve 208 and the limiting sleeve 209 provides a certain buffer and sealing effect for the filter element 3 during installation, while ensuring the installation stability of the filter element 3.

[0042] Working principle: When filter element 3 needs to be replaced, first rotate the handle 205 to rotate the threaded rod 204, thereby causing the rotating frame 206 and the locking rod 207 to descend, allowing the locking rod 207 to descend vertically away from the locking groove 105, thus unlocking the sealing cover 201. Then rotate the entire rotating frame 206 to make the locking rod 207 avoid the locking groove 105, so that when the sealing cover 201 is lifted, the locking rod 207 will not contact the locking groove 105. Then, directly remove the entire sealing cover 201. The limiting sleeve 209 is nested inside the rubber sleeve 208. When removing the sealing cover 201, the limiting sleeve 209 will fall out of the rubber sleeve 208 because it loses the downward pressure from above. Remove the filter element 3 and vertically nest it outside the mounting tube 103 from the top opening of the outer shell 1. Ensure that the top of the filter element 3 abuts against the limiting sleeve 209. Then, cover the top of the outer shell 1 with the sealing cap 201, making the sealing ring 106 fit tightly against the bottom of the sealing cap 201. Next, rotate the rotating frame 206 so that the position of the locking rod 207 corresponds to the locking groove 105. Then, rotate the handle 205 to move the threaded rod 204 upward, causing the rotating frame 206 and locking rod 207 to rise, so that the four locking rods 207 slide into the locking groove 105 on the side of the outer shell 1 along the chamfer, achieving uniform locking. At this time, the rubber sleeve 208 is deformed under pressure, providing elastic sealing and cushioning for the filter element 3. During filtration, the liquid enters the outer shell 1 from the inlet pipe 101, is filtered by the filter element 3, and flows into the outlet pipe 104 through the holes in the side wall of the mounting tube 103.
