Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a compressor dry gas sealing energy-saving gas purification device. Background Technology

[0002] Compressors, as driven fluid machinery that raises low-pressure gas to high-pressure gas, are widely used in industrial production. Dry gas seals, as a key sealing method for compressors, have extremely high requirements for the cleanliness of the incoming gas. Impurities in the gas directly affect the sealing effect and equipment lifespan. Therefore, it is necessary to purify the external air through a gas purification device. Currently, existing compressor gas purification devices usually use a single purification structure to filter impurities in the external air, which cannot achieve graded interception, resulting in poor gas purification effect.

[0003] As disclosed in the prior art, Chinese utility model publication CN220015434U discloses an air filtration device for a gas compressor. This utility model includes a gas compressor body and a gas compressor inlet pipe. An assembly connecting pipe is provided at the outer end of the gas compressor inlet pipe, and a filter tank is provided at the outer end of the assembly connecting pipe. A rear-side uniform flow perforation plate is provided inside the filter tank. An intermediate filter element is provided on the outer side of the rear-side uniform flow perforation plate on the filter tank. A front-side uniform flow perforation plate is provided on the outer side of the intermediate filter element on the filter tank. In the above structure, the gas is purified and filtered only through the filter element. In actual operation, a single filter element cannot achieve graded interception, resulting in fine particles or oil mist easily penetrating. The purified gas may still contain harmful impurities, affecting the long-term stable operation of the compressor. That is, the single purification structure mentioned above has the problem of poor gas purification effect. Therefore, we need to propose a compressor dry gas sealing energy-saving gas purification device. Utility Model Content

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A compressor dry gas sealing energy-saving gas purification device includes: a compressor body 1; a connecting pipe 2, one end of which is connected to one side of the compressor body 1; a purification tank 3, one side of which is connected to the other end of the connecting pipe 2; and a multi-stage purification mechanism 4 for performing graded purification and filtration of gas, wherein the multi-stage purification mechanism 4 is installed inside the purification tank 3.

[0024] With the compressor body 1, connecting pipe 2, purification tank 3 and multi-stage purification mechanism 4, the multi-stage purification mechanism 4 can perform graded purification and filtration of the gas entering the purification tank 3. The purified gas enters the compressor body 1 through the connecting pipe 2. Therefore, the multi-stage purification mechanism 4 can achieve multi-stage purification of impurities of different particle sizes, solve the problem of incomplete purification of traditional single purification structure, improve the gas purification effect, and ensure the stable operation of the compressor dry gas sealing system.

[0025] Specifically, the multi-stage purification mechanism 4 includes a fixed cylinder 41, a first filter screen 42, a second filter screen 43, and a third filter screen 44; the fixed cylinder 41 is installed inside the purification tank 3, and the first filter screen 42, the second filter screen 43, and the third filter screen 44 are installed inside the fixed cylinder 41 from left to right.

[0026] With the fixed cylinder 41, the first filter screen 42, the second filter screen 43, and the third filter screen 44 arranged from left to right, the fixed cylinder 41 provides the installation base for the first filter screen 42, the second filter screen 43, and the third filter screen 44. The three filter screens are arranged from left to right, so that the gas passes through the first filter screen 42, the second filter screen 43, and the third filter screen 44 in stages for filtration. This allows for the interception of impurities of different particle sizes. The first filter screen 42 mainly removes large particles, the second filter screen 43 filters medium-sized particles, and the third filter screen 44 further purifies fine particles and oil mist, thereby achieving progressive and efficient purification filtration.

[0027] The purification tank 3 has multiple sets of snap-fit ​​blocks 5 fixedly installed inside, and the outer side of the fixed cylinder 41 has multiple sets of snap-fit ​​grooves 6 for snap-fit ​​blocks 5 to snap into, and the multiple sets of snap-fit ​​grooves 6 and multiple sets of snap-fit ​​blocks 5 are arranged in a ring array.

[0028] With the setting of snap-fit ​​blocks 5 and snap-fit ​​grooves 6, multiple sets of snap-fit ​​blocks 5 inside the purification tank 3 and multiple sets of snap-fit ​​grooves 6 on the outside of the fixed cylinder 41 are snapped in a ring array, which can quickly realize the initial positioning and installation of the fixed cylinder 41 inside the purification tank 3, improve the convenience and stability of the installation of the fixed cylinder 41, prevent the fixed cylinder 41 from shaking or shifting during gas flow, and ensure the stable operation of the graded purification process.

[0029] Specifically, a fixing plate 7 is fixedly installed inside the purification tank 3, and a through hole 8 is opened inside the fixing plate 7.

[0030] With the setting of the fixing plate 7 and the through hole 8, the fixing plate 7 can further support and limit the fixing cylinder 41, and enhance the stability of the installation of the fixing cylinder 41. The through hole 8 can guide the purified gas, so that the gas is evenly and stably delivered to the compressor body 1 through the connecting pipe 2, and avoid the gas flow disorder affecting the normal operation of the compressor.

[0031] In a further preferred embodiment, a plurality of limiting posts 9 are fixedly installed on the side of the fixed cylinder 41 near the fixed plate 7, and a limiting hole 10 for the limiting posts 9 to be inserted is provided on one side of the fixed plate 7.

[0032] With the setting of the limiting post 9 and the limiting hole 10, the limiting post 9 on the fixed cylinder 41 is inserted into the limiting hole 10 on the fixed plate 7, which further strengthens the connection and positioning between the fixed cylinder 41 and the purification tank 3, effectively preventing the fixed cylinder 41 from moving in the axial and radial directions, ensuring the structural stability of the multi-stage purification mechanism 4 during the working process, and ensuring the consistency of the filtration and purification effect.

[0033] Specifically, the fixed cylinder 41 has multiple sets of bolts 11 inserted inside, and the purification tank 3 has multiple sets of threaded holes 12 for the bolts 11 to be threaded into.

[0034] With multiple sets of bolts 11 and multiple sets of threaded holes 12, the fixed cylinder 41 is threadedly connected to the threaded holes 12 inside the purification tank 3 through multiple sets of bolts 11, which realizes the firm fixation of the fixed cylinder 41 inside the purification tank 3, making the fixed cylinder 41 less prone to loosening during long-term use. At the same time, the bolt 11 connection facilitates the disassembly and replacement of the multi-stage purification mechanism 4 in the later stage, ensuring the purification effect on the gas.

[0035] Among them, multiple sets of snap-fit ​​grooves 6 and multiple sets of limiting posts 9 are arranged alternately and in a staggered manner, and multiple sets of snap-fit ​​grooves 6 and multiple sets of bolts 11 are arranged alternately and in a staggered manner.

[0036] By staggered and alternating arrangement of multiple sets of snap-fit ​​grooves 6, multiple sets of limiting posts 9, and multiple sets of bolts 11, fixing points can be evenly distributed in the circumferential direction of the fixing cylinder 41, avoiding stress concentration, enhancing the overall stability and structural strength of the fixing cylinder 41 installation, ensuring the stability of the multi-stage purification mechanism 4 under gas pressure, and extending the service life of the device.

[0037] Specifically, the end of the purification tank 3 away from the connecting pipe 2 is installed on the sealing cover 13, and the end of the sealing cover 13 away from the purification tank 3 is connected to the air inlet pipe 14.

[0038] With the sealing cap 13 and the air inlet pipe 14, the sealing cap 13 at the end of the purification tank 3 away from the connecting pipe 2 can seal the inside of the purification tank 3, preventing unpurified gas from mixing in or purified gas from leaking, thus ensuring the airtightness of the purification environment. The air inlet pipe 14 connected to one end of the sealing cap 13 facilitates the smooth entry of external gas into the purification tank 3 for purification treatment, realizing the orderly input of gas. At the same time, opening the sealing cap 13 also facilitates the disassembly and replacement of the multi-stage purification mechanism 4, improving the practicality and ease of use of the device.

[0039] Working principle: When this utility model is in use, the gas first enters the purification tank 3 through the air inlet pipe 14, and flows to the multi-stage purification mechanism 4 under the guidance of the sealing cover 13. The gas passes through the first filter screen 42, the second filter screen 43 and the third filter screen 44 in sequence for graded filtration. These three filter screens are arranged from left to right to intercept impurities of different particle sizes. The first filter screen 42 mainly removes large particles, the second filter screen 43 filters medium-sized particles, and the third filter screen 44 further purifies fine particles and oil mist, thereby achieving progressive and efficient purification filtration. The purified gas passes through the through hole 8 on the fixed plate 7 and is transported to the compressor body 1 through the connecting pipe 2, meeting the requirements of dry gas seal for gas cleanliness and ensuring the normal operation of the compressor body 1.

[0040] 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.
