Description

Technical Field

[0001] This application relates to the field of filter technology, and in particular to a filter structure. Background Technology

[0002] Water vapor in the air source has a low dew point temperature and is easily liquefied at room temperature. The liquefied water can easily cause corrosion and jamming of various control valves and actuators in pneumatic control components, thus affecting the reliability of the pneumatic execution system. Currently, conventional air filters in China have low operating pressure and low water filtration efficiency. They can only filter solid impurities and large-diameter water droplets in the air, but cannot filter fine water droplets. When unfiltered fine water droplets in the air enter the downstream control or actuator components of the system, they can cause corrosion and jamming of internal precision components, affecting the safe operation of the system. Utility Model Content

[0003] The purpose of this invention is to provide a filter core structure that addresses the defects and shortcomings of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The device includes an upper cover, a lower cover, and a filter assembly. The filter assembly is located between the upper cover and the lower cover. The upper end of the lower cover has a circumferentially oriented collection groove. The lower end of the filter assembly is inserted into the collection groove. The lower end of the lower cover is connected to a collection hopper. The lower cover has a connecting hole at the bottom of the collection groove, which connects the collection groove and the collection hopper. The lower end of the collection hopper is fitted with a water collection bag.

[0006] Preferably, the lower end of the collecting hopper has a water outlet, the water collection bag is fitted around the water outlet, and a locking sleeve is fitted around the water outlet. The locking sleeve consists of two semi-rings, one end of the two semi-rings is hinged together, and the other end of the two semi-rings is interlocked.

[0007] Preferably, a fixing ring is provided on the outer periphery of the outlet, and a ring groove is provided on the inner periphery of the locking sleeve for the fixing ring to be engaged and fixed.

[0008] Preferably, a limiting ring is provided on the upper circumferential side of the collecting hopper, the upper end of the collecting hopper is threaded to the lower end of the lower end cover, and the upper side of the limiting ring abuts against the lower end of the lower end cover.

[0009] Preferably, a mounting post is provided in the middle of the upper end of the lower end cover, the mounting post is threaded and rotates inside the lower end of the filter assembly, and the upper end of the mounting post is conical.

[0010] Preferably, the periphery of the limiting ring is provided with anti-slip texture.

[0011] Preferably, a sealing ring is provided between the filter assembly and the collection tank, and the sealing ring is fitted around the periphery of the mounting column.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When the filter element is in use, the air source is easily liquefied at room temperature after passing through the filter element. The water will then slide into the collection tank, and then fall into the collection hopper through the connecting hole. Finally, the water enters the water collection bag through the outlet, so that the precision parts are not affected by the water, and the precision parts are not corroded, thus improving the stability of the filter element.

[0014] 2. When the water collection bag needs to be disassembled, unfasten the two interlocking halves to remove the locking sleeve from the outlet. Then, pull the water collection bag out of the outlet, drain the water inside, and then place the opening of the water collection bag over the outlet. With the stabilizing ring, the water collection bag is pre-fixed to the outlet. Finally, fasten the locking sleeve to the outlet to lock the water collection bag in place, thus improving the ease of disassembling the water collection bag. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] This application discloses a filter core structure.

[0021] Reference Figure 1 and Figure 2The device includes an upper cover 1, a lower cover 2, and a filter assembly 3. The filter assembly 3 includes a filter screen 4 and a bracket 5. The filter screen 4 is fixed to the outer periphery of the bracket 5. A connecting groove is circumferentially opened on the lower end face of the upper cover 1, and a collection groove 6 is circumferentially opened on the upper end face of the lower cover 2. The upper end of the bracket 5 is fixed in the connecting groove by bolts. The lower ends of the bracket 5 and the filter screen 4 are inserted into the collection groove 6. A mounting post 7 is formed by bending the middle part of the lower cover 2. The upper end of the mounting post 7 is threadedly connected to the lower end of the bracket 5. The upper end of the mounting post 7 is conical.

[0022] Reference Figure 2 and Figure 3 A sealing ring 8 is placed at the lower end of the bracket 5. The sealing ring 8 is located inside the collection groove 6 and is fitted around the periphery of the mounting post 7. When the mounting post 7 is threaded into the lower end of the bracket 5, the collection groove 6 and the bracket 5 compress the sealing ring 8, improving the sealing performance between the bracket 5 and the lower end cover 2.

[0023] A collection hopper 9 is placed at the lower end of the lower end cover 2. A connecting ring 10 is integrally provided on the outer periphery of the lower end of the lower end cover 2. The upper end of the collection hopper 9 is threaded to the inner periphery of the connecting ring 10. A limiting ring 11 is integrally provided on the outer periphery of the collection hopper 9. The upper side of the limiting ring 11 abuts against the lower end of the connecting ring 10. Anti-slip texture 12 is integrally provided on the periphery of the limiting ring 11.

One end of the two half rings 19 is hinged and the other end of the two half rings 19 is fastened by a buckle. Disconnect one end of the two interlocking half-rings 19 to remove the locking sleeve 17 from the outlet 15. Then, remove the water collection bag 14 from the outlet 15 and treat the water inside the water collection bag 14. Place the opening of the water collection bag 14 onto the outlet 15 and pre-fix the water collection bag 14 to the outlet 15 with the stabilizing effect of the fixing ring 16. Then, fasten the locking sleeve 17 onto the outlet 15, thereby locking the water collection bag 14 onto the outlet 15.
