A gas filter device for a compressor

Abstract

This utility model relates to the field of gas compressor technology, specifically a gas filtration device for a compressor, including a tank. The bottom of the tank has a connecting pipe that connects to the compressor's gas tank. Sliding grooves are formed on opposite sides of the inner sidewall of the tank. A rotating filter bag is located inside the tank. A mounting ring is located at the top of the filter bag, and a second mounting ring is located at the bottom. A slider adapted to the sliding groove is located on the sidewall of the second mounting ring. The outer wall of the second mounting ring is threaded to the inner wall of the top of the tank. A filter plate is mounted on the second mounting ring. By rotating the filter bag, it is divided into upper and lower filtration spaces. Because the filter bag rotates in the middle, a third space is formed between the middle of the filter bag and the inner wall of the tank. External dust and impurities must pass through the upper space of the filter bag into the third space, and then through the third space into the lower space of the filter bag.

Description

Technical Field

[0001] This utility model relates to the field of gas compressor technology, specifically a gas filtration device for a compressor. Background Technology

[0002] The gas compressor filtration system is a key component for ensuring the normal operation and extending the service life of the compressor. Its main function is to filter and purify the gas entering the compressor, removing impurities.

[0003] Patent document CN223004125U discloses an air filtration device for a gas compressor. This device includes a gas compressor body, with an inlet pipe connected to one end. A flange connects the inlet pipe to a tank, which contains a backflushing assembly. A fan is located on one side of the tank, with one end of the fan connected to a filter box via a pipe. Three suction pipes are connected to one side of the filter box via pipes, with one end of each suction pipe connected to the outside of the tank. This device solves the problem that existing devices, which use a flow-dispersing perforated plate on both sides of the filter element to evenly disperse air input for filtration through numerous small holes, are prone to clogging by dust and impurities. This affects the filtration effect of the filter element and the compressor's intake efficiency, and is also inconvenient to disassemble and clean, making them difficult to use.

[0004] The above solution filters dust and impurities by setting up multiple layers of filter screens with different pore sizes. Although it can be cleaned with a cleaning brush, the cleaning effect is worse than cleaning the filter screens directly. Furthermore, removing the multiple layers of filter screens separately is a cumbersome process and increases the labor intensity of the operators. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a gas filtration device for compressors. By twisting the filter bag, the filter bag is divided into upper and lower filtration spaces. Since the middle of the filter bag is twisted, a third space is formed between the middle of the filter bag and the inner wall of the tank. External dust and impurities need to enter the third space through the upper space of the filter bag, and then enter the lower space of the filter bag through the third space, and then enter the bottom of the tank through the filter plate.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A gas filtration device for a compressor includes a tank. The bottom of the tank is provided with a connecting pipe that connects to the compressor gas tank. Sliding grooves are provided on opposite sides of the inner sidewall of the tank. A rotating filter bag is provided inside the tank. The top of the filter bag is provided with a mounting ring one, and the bottom of the filter bag is provided with a mounting ring two. The sidewall of the mounting ring two is provided with a slider that matches the sliding groove. The outer wall of the mounting ring two is threadedly connected to the inner wall of the top of the tank. A filter plate is mounted on the mounting ring two.

[0008] Preferably, the filter bag has a first filter hole at the top center, a second filter hole at the bottom center, and a third filter hole on the filter plate.

[0009] Preferably, the diameter of the first filter pore is larger than the diameter of the second filter pore, and the diameter of the second filter pore is larger than the diameter of the third filter pore.

[0010] Preferably, the bottom of the groove is provided with a magnetic block, and the bottom of the slider is magnetic.

[0011] Preferably, the diameter of the first mounting ring is larger than the diameter of the second mounting ring, and the top of the first mounting ring is provided with a rotating ring, which is provided with anti-slip texture.

[0012] Preferably, the outer wall of the top of the tank is provided with a limiting block, and the side wall of the rotating ring is provided with a mounting block that cooperates with the limiting block. Both the mounting block and the limiting block are provided with through holes, and a limiting pin is inserted into the through hole.

[0013] Preferably, the top of the mounting ring is provided with a top cover, and the top cover is provided with a handle in the middle of its upper end.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model has a simple structure. By twisting the filter bag, it is divided into upper and lower filtration spaces. Due to the twisting in the middle of the filter bag, a third space is formed between the middle of the filter bag and the inner wall of the tank. External dust and impurities need to enter the third space through the upper space of the filter bag, and then enter the lower space of the filter bag through the third space. Finally, they pass through the filter plate and enter the bottom of the tank. This device achieves a multi-layer filtration effect. When cleaning the filtration device, only the filter bag and filter plate need to be cleaned, allowing the filtration device to be removed in one go, reducing the labor intensity of operators.

[0016] 2. When the filter bag of this device is twisted, external dust and impurities enter the third space through the first filter hole, then enter the lower part of the filter bag through the second filter hole, and are filtered through the third filter hole on the filter plate. The device achieves the effect of multi-stage filtration.

[0017] 3. Larger dust and impurities on the outside of this device are filtered by the first filter hole, smaller dust and impurities can be filtered by the second filter hole, and finally the third filter hole can filter out even finer dust, ensuring the filtration effect of this device.

[0018] 4. This device features a limiting block at the top of the tank and an installation block on the side wall of the rotating ring. Through holes are provided in the limiting block and the installation block to facilitate locking the rotating ring with a limiting pin, thus preventing the rotating ring from rotating freely at the top of the tank.

[0019] 5. The top cover of this device can completely cover the mounting ring to prevent external dust from entering, and the handle makes it easy to remove and place the top cover from the mounting ring. Attached Figure Description

[0027] 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.

[0028] Example 1

[0029] A gas filtration device for a compressor, with the structure as follows: Figures 1-6 As shown, the device includes a tank body 1. The bottom of the tank body 1 is provided with a connecting pipe 14 that connects to the compressor tank. The inner sidewalls of the tank body 1 are provided with sliding grooves 2 on opposite sides. The tank body 1 is provided with a rotating filter screen 9. The top of the filter screen 9 is provided with a mounting ring 3, and the bottom of the filter screen 9 is provided with a mounting ring 4. The sidewall of the mounting ring 4 is provided with a slider 5 that matches the sliding groove 2. The outer wall of the mounting ring 4 is connected to the inner wall of the top of the tank body 1 by a thread 8. A filter plate 10 is installed on the mounting ring 4.

[0030] Gas containing dust and impurities from the outside passes through the filter bag 9 inside the tank 1 to filter the dust and impurities, and then enters the gas storage tank through the connecting pipe 14 at the bottom of the tank 1. The filter bag 9 has a second mounting ring 4 at the bottom and a first mounting ring 3 at the top. After the filter bag 9 has been used for a long time, a large amount of dust and impurities will accumulate. The operator can rotate the first mounting ring 3 to separate the first mounting ring 3 from the top of the tank 1. At this time, the rotated filter bag 9 returns to a straight cylindrical shape. The operator pulls the first mounting ring 3 upward, and the filter bag 9 moves the second mounting ring 4 upward from the inside of the tank 1. At this time, the filter bag 9 can be removed from the inside of the tank 1 for the operator to clean.

[0031] After the filter bag 9 is cleaned, the operator places the second mounting ring 4 on top of the tank 1, ensuring that the slider 5 on the second mounting ring 4 is inserted into the groove 2. Under its own weight, the second mounting ring 4 pulls the filter bag 9 into the tank 1. When the slider 5 reaches the bottom of the groove 2, the operator rotates the first mounting ring 3 180° to connect the first mounting ring 3 to the top of the tank 1 via the thread 8. Due to the cooperation between the slider 5 and the groove 2, the second mounting ring 4 cannot rotate synchronously with the first mounting ring 3. Therefore, the middle of the filter bag 9 will twist, causing the filter bag 9 to split. The upper and lower filtration spaces are combined. Due to the twisting of the middle of the filter bag 9, a third space is formed between the middle of the filter bag 9 and the inner wall of the tank 1. External dust and impurities need to enter the third space through the upper space of the filter bag 9, then enter the lower space of the filter bag 9 through the third space, and then enter the bottom of the tank 1 through the filter plate 10. This device achieves a multi-layer filtration effect. When cleaning the filtration device, only the filter bag 9 and the filter plate 10 need to be cleaned, allowing the filtration device to be removed in one go, reducing the labor intensity of the operators.

[0032] The filter mesh bag 9 has a first filter hole 11 above the middle, a second filter hole 12 below the middle, and a third filter hole 13 on the filter plate 10.

[0033] When the filter bag 9 is twisted, external dust and impurities enter the third space through the first filter hole 11, then enter the lower part of the filter bag 9 through the second filter hole 12, and are filtered through the third filter hole 13 on the filter plate 10. The effect of multi-stage filtration is achieved through one device.

[0034] The diameter of the first filter hole 11 is larger than the diameter of the second filter hole 12, and the diameter of the second filter hole 12 is larger than the diameter of the third filter hole 13.

[0035] Larger dust and impurities are filtered by the first filter hole 11, smaller dust and impurities are filtered by the second filter hole 12, and finally, even finer dust is filtered by the third filter hole 13, ensuring the filtration effect of this device.

[0036] The bottom of the slide 2 is provided with a magnetic block 6, and the bottom of the slider 5 is magnetic.

[0037] The slider 5 and the magnetic block 6 are magnetically connected to ensure the stability of the mounting ring 4 and prevent the mounting ring 4 from bouncing upwards during operation. At the same time, it can also ensure that the filter bag 9 is kept taut when it is twisted, thus ensuring the filtration effect of dust and impurities.

[0038] The diameter of the mounting ring 3 is larger than the diameter of the mounting ring 4. The top of the mounting ring 3 is provided with a rotating ring 7, and the rotating ring 7 is provided with anti-slip texture.

[0039] Ensure that the second mounting ring 4 can slide along the inner wall of the tank 1 towards the bottom of the tank 1, preventing the first mounting ring 3 from entering the tank 1. Ensure that the first mounting ring 3 can be connected to the inner wall of the top of the tank 1 through the thread 8, ensuring the stability of the filter bag 9 during use. At the same time, a rotating ring 7 with anti-slip texture is provided on the top of the first mounting ring 3, which makes it easy for the operator to rotate the first mounting ring 3.

[0040] The outer wall of the top of the tank body 1 is provided with a limiting block 15, and the side wall of the rotating ring 7 is provided with an installation block 16 that cooperates with the limiting block 15. Both the installation block 16 and the limiting block 15 are provided with through holes 17, and a limiting pin 18 is inserted into the through hole 17.

[0041] To prevent the installation ring 3 from rotating at the top of the tank 1 due to vibration during use, which would cause the filter bag 9 to change from a twisted state to a straight state and affect the filtration effect on dust and impurities, a limiting block 15 is set at the top of the tank 1, and an installation block 16 is set on the side wall of the rotating ring 7. Through holes 17 are set on the limiting block 15 and the installation block 16 to facilitate locking the rotating ring 7 with the limiting pin 18, thus preventing the rotating ring 7 from rotating freely at the top of the tank 1.

[0042] Example 2

[0043] Based on Embodiment 1, the top of the mounting ring 3 is provided with a top cover 19, and the top cover 19 is provided with a handle 20 in the middle of its upper end.

[0044] When not in use, external dust and impurities are prevented from falling on the filter bag 9. The top cover 19 completely covers the mounting ring 3 to prevent external dust from entering. The handle 20 makes it easy to remove and place the top cover 19 from the mounting ring 3.

[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations, additions, subtractions, or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
