Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a fine filter for gas treatment. Background Technology

[0002] Fine filters are devices used to efficiently remove minute impurities from fluids. They are particularly important in the field of gas treatment. In gas treatment, they can remove dust, rust, liquid water, hydrocarbon droplets, etc., from the natural gas extraction, transportation and application process, preventing impurities from causing wear, corrosion or blockage to equipment such as pipelines, valves, and gas turbines, and ensuring the safe and efficient operation of the system.

[0003] In existing technologies, after prolonged processing of gas, fine filters often accumulate dust particles that clog the filter element, reducing its filtration efficiency. Furthermore, the presence of corrosive substances in the gas can damage the filter element. However, many fine filters use screws to secure the filter element, requiring the system to be shut down to ensure no pressure or fluid flow. If power is involved, the power must be disconnected. Then, the screws securing the filter element must be loosened with a screwdriver before the filter housing can be opened to remove the filter element. This process is overly complicated and wastes too much time. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fine filter for gas treatment, which solves the problem mentioned in the background art that the operation of loosening the screws fixing the filter element with a screwdriver to remove the filter element is too complicated.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fine filter for gas treatment, comprising a cylinder and a filter element, wherein a first sealing cap is provided on the cylinder, one end of the first sealing cap is fixedly connected to and communicates with the top end of the cylinder, the first sealing cap is detachably connected to a second sealing cap by a plurality of bolts, the second sealing cap is provided with a handle, the filter element is slidably disposed in the cylinder, and further comprising a rotating ring, a transverse fixing component and a longitudinal fixing component, the rotating ring being fitted onto the outer side wall of the top end of the filter element and rotatably connected to the filter element, the transverse fixing component being disposed at the bottom end of the filter element for transverse fixing of the filter element, and the longitudinal fixing component being disposed on the rotating ring for longitudinal fixing of the filter element.

[0008] Preferably, the transverse fixing component includes a fixing ring, multiple dovetail blocks and dovetail grooves. The fixing ring is fitted onto the bottom end of the filter element and is fixedly connected to the filter element. The multiple dovetail blocks are distributed circumferentially around the axis of the fixing ring and are fixedly connected to the outer side wall of the fixing ring. The cylinder body is provided with multiple dovetail grooves that cooperate with the dovetail blocks.

[0009] Furthermore, the longitudinal fixing assembly includes multiple sliders, grooves, and snap-fit ​​components. The multiple sliders are circumferentially distributed around the axis of the rotating ring and fixedly connected to the outer wall of the rotating ring. The cylinder has grooves that cooperate with the sliders. The sliders slide in contact with the inner wall of the grooves. The snap-fit ​​components are disposed on the inner top walls of the sliders and the grooves to restrict the rotation of the rotating ring.

[0010] Furthermore, the snap-fit ​​component includes a connecting spring, a snap-fit ​​ball, and snap-fit ​​holes. The dovetail block has a through groove that mates with the connecting spring. One end of the connecting spring is fixedly connected to the inner bottom wall of the through groove. One end of the snap-fit ​​ball is fixedly connected to the other end of the connecting spring.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a fine filter for gas treatment, which has the following advantages:

[0016] In this utility model, by setting a rotating ring, a horizontal fixing component and a vertical fixing component, when installing the filter element, multiple sliders and multiple dovetail blocks are respectively matched with multiple dovetail grooves one by one, and the filter element is driven to move vertically, so that the dovetail blocks and sliders are inserted into the dovetail grooves in sequence. This can maintain the stability of the filter element in the lateral direction and prevent the filter element from rotating horizontally.

[0017] After the retaining ring is supported by the retaining ring, the rotating rod drives the snap-fit ​​ball into the snap-fit ​​hole, thus fixing the rotating ring and preventing the rotating ring from continuing to rotate and causing the slider to move back to the dovetail groove, thus preventing the longitudinal fixation of the filter element from being unstable.

[0018] When it is necessary to disassemble the filter element, simply rotate the rotating ring in the same direction as when installing the filter element by holding the rotating rod. The rotating ring drives the slider to move to the next corresponding dovetail groove. Then, pull the rotating rod upward to remove the filter element. Compared with manually using a screwdriver to loosen the screws that fix the filter element and then removing the filter element, this is more convenient and saves manpower.

[0019] Therefore, this fine filter for gas treatment solves the problem mentioned in the background art of the prior art, which involves using a screwdriver to loosen the screws fixing the filter element and then removing the filter element, making the operation too complicated.

Detailed Implementation

[0026] 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.

[0027] Example

[0028] Please see Figures 1 to 5A fine filter for gas treatment includes a cylinder 1 and a filter element 2. A first sealing cover 15 is provided on the cylinder 1. One end of the first sealing cover 15 is fixedly connected to and communicates with the top end of the cylinder 1. The first sealing cover 15 is detachably connected to a second sealing cover 16 by multiple bolts 17. A handle 18 is provided on the second sealing cover 16. The filter element 2 is slidably disposed in the cylinder 1. The filter element 2 also includes a rotating ring 3, a transverse fixing component and a longitudinal fixing component. The rotating ring 3 is fitted on the outer side wall of the top end of the filter element 2 and is rotatably connected to the filter element 2. Two rotating rods 14 are symmetrically provided at the top end of the rotating ring 3 for rotating and lifting the filter element 2. By unscrewing the multiple bolts 17 and then pulling the handle 18, the second sealing cover 16 is removed. At this time, the second sealing cover 16 is in communication with the cylinder 1. The rotating rods 14 are held to drive the filter element 2 that needs to be replaced or cleaned into the cylinder 1.

[0029] like Figure 3 and Figure 5 As shown, the transverse fixing assembly is set at the bottom of the filter element 2 for transverse fixing of the filter element 2. The transverse fixing assembly includes a fixing ring 4, multiple dovetail blocks 5 and dovetail grooves 6. The fixing ring 4 is fitted onto the bottom of the filter element 2 and is fixedly connected to the filter element 2. The multiple dovetail blocks 5 are distributed circumferentially around the axis of the fixing ring 4 and are fixedly connected to the outer wall of the fixing ring 4. The cylinder 1 has multiple dovetail grooves 6 that cooperate with the dovetail blocks 5. Before placing the filter element 2 in the cylinder 1, the worker holds the rotating rod 14 to keep the filter element 2 stationary. By corresponding the multiple dovetail blocks 5 with the multiple dovetail grooves 6 one by one, the filter element 2 is moved longitudinally. The filter element 2 drives the fixing ring 4 to move, and the fixing ring 4 drives the multiple dovetail blocks 5 to move, so that the dovetail blocks 5 are inserted into the dovetail grooves 6. This can keep the filter element 2 stable in the transverse direction and prevent the filter element 2 from rotating horizontally.

[0030] like Figure 3 , Figure 4 and Figure 5As shown, the longitudinal fixing assembly is set on the rotating ring 3 for longitudinally fixing the filter element 2. The longitudinal fixing assembly includes multiple sliders 7, grooves 8, and snap-fit ​​components. The multiple sliders 7 are distributed circumferentially around the axis of the rotating ring 3 and are fixedly connected to the outer wall of the rotating ring 3. The sliders 7 are dovetail-shaped and cooperate with the dovetail grooves 6. The first sealing cover 15 also has multiple dovetail grooves 6 that cooperate with the sliders 7 and the dovetail blocks 5. The cylinder 1 has grooves 8 that cooperate with the sliders 7. The sliders 7 slide in contact with the inner wall of the grooves 8. The snap-fit ​​components are set on the inner top wall of the sliders 7 and the grooves 8 to restrict the rotation of the rotating ring 3. The snap-fit ​​components include connecting springs 9, snap-fit ​​balls 10, and snap-fit ​​holes 11. The dovetail blocks 5 have through grooves that cooperate with the connecting springs 9. One end of the connecting springs 9 is fixedly connected to the inner bottom wall of the through groove. The snap-fit ​​balls 10 and 11 are also fixedly connected to the filter element 2. One end of 0 is fixedly connected to the other end of the connecting spring 9. The dovetail groove 6 is provided with an abutment part 13 that cooperates with the snap-fit ​​ball 10. The cylinder 1 is provided with multiple snap-fit ​​holes 11 that cooperate with the snap-fit ​​ball 10. The snap-fit ​​holes 11 are connected to the slide groove 8. One end of the snap-fit ​​hole 11 is provided with a recess 12. The recess 12 cooperates with the snap-fit ​​ball 10. By rotating the rotating ring 3, the rotating ring 3 drives multiple sliders 7 to rotate. Multiple sliders 7 and multiple dovetail blocks 5 need to be respectively aligned with multiple dovetail grooves 6. Then, the filter element 2 is driven to move longitudinally so that the dovetail blocks 5 and sliders 7 are inserted into the dovetail grooves 6 in sequence. During the downward movement, a retaining ring 19 is provided on the inner side wall of the bottom of the cylinder 1 to support the fixing ring 4. When the fixing ring 4 is supported by the retaining ring 19, the slider 7 and the slide groove 8 are on the same horizontal line.

[0031] Then, by holding the rotating rod 14, the rotating ring 3 is rotated around its axis, which drives the slider 7 to rotate horizontally. The slider 7 drives the locking ball 10 to rotate. During the rotation, the locking ball 10 contacts and squeezes the abutment part 13, causing the locking ball 10 to move downward and squeeze the connecting spring 9. The connecting spring 9 contracts, and the locking ball 10 moves into the through groove and completely enters the through groove. This allows the slider 7 to move horizontally in the slide groove 8. When the slider 7 drives the locking ball 10 to the locking hole 11 corresponding to the locking ball 10, the rotation of the rotating ring 3 is temporarily stopped. The locking ball 10 is pushed into the locking hole 11 by the elastic force of the connecting spring 9. This completes the fixation of the rotating ring 3, preventing the rotating ring 3 from continuing to rotate and causing the slider 7 to move back to the dovetail groove 6, thus preventing the longitudinal fixation of the filter element 2 from being unstable.

[0032] Working principle: When installing the filter element 2 of this fine gas treatment filter, the filter element 2 is held by hand and the rotating ring 3 is rotated while the filter element 2 is stable. The rotating ring 3 drives multiple sliders 7 to rotate. Multiple sliders 7 and multiple dovetail blocks 5 need to be aligned with multiple dovetail grooves 6 one by one. Then, the filter element 2 is moved longitudinally so that the dovetail blocks 5 and sliders 7 are inserted into the dovetail grooves 6 in sequence. This can keep the filter element 2 stable in the lateral direction and prevent the filter element 2 from rotating horizontally.

[0033] During the downward movement of filter element 2, a retaining ring 19 is provided on the inner wall of the bottom of cylinder 1 to support the fixing ring 4. When the fixing ring 4 is supported by the retaining ring 19, the slider 7 and the slide groove 8 are on the same horizontal line. Then, by holding the rotating rod 14, the rotating ring 3 is rotated around the axis of the rotating ring 3, which drives the slider 7 to rotate horizontally. The slider 7 drives the locking ball 10 to rotate. During the rotation, the locking ball 10 contacts and squeezes the abutment part 13, causing the locking ball 10 to move downward and squeeze the connecting spring 9, connecting... When the spring 9 contracts, the locking ball 10 moves into the through groove and fully enters the through groove, allowing the slider 7 to move horizontally within the slide groove 8. When the slider 7 moves the locking ball 10 to the locking hole 11 corresponding to the locking ball 10, the rotation of the rotating ring 3 is temporarily stopped. The locking ball 10 is pushed into the locking hole 11 by the elastic force of the connecting spring 9, thus completing the fixation of the rotating ring 3 and preventing the rotating ring 3 from continuing to rotate and causing the slider 7 to move back to the dovetail groove 6, thus preventing the longitudinal fixation of the filter element 2 from being unstable.

[0034] When it is necessary to disassemble the filter element 2, simply rotate the rotating ring 3 in the same direction as when installing the filter element 2 by holding the rotating rod 14. The rotating ring 3 drives the slider 7 to rotate, and the slider 7 drives multiple locking balls 10 to rotate and press the connecting spring 9 along the inner wall of the recess 12. The connecting spring 9 retracts, and the locking balls 10 enter the through groove. The slider 7 continues to move in the slide groove 8 and transfers to the next corresponding dovetail groove 6. Then, the filter element 2 can be removed by lifting the rotating rod 14. This is convenient to operate and saves manpower.

[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.
