Description

Technical Field

[0001] This utility model relates to a compressor filtration device, and more particularly to a distributed and compact high-efficiency compressor filtration device. Background Technology

[0002] A reciprocating compressor is a type of compressor that uses the reciprocating motion of a piston to pressurize and transport gas. It is a positive displacement compressor, also known as a "reciprocating piston compressor" or "reciprocating compressor." It mainly consists of a working chamber, transmission components, a casing, and auxiliary components. The working chamber comprises a cylinder, cylinder liner, valves, packing, piston, and piston rod. The piston, including the piston rod, drives the piston to reciprocate within the cylinder. The volumes of the working chambers on either side of the piston alternately change in opposite directions. On the side with a smaller volume, gas is discharged through the valve due to increased pressure, while on the side with a larger volume, gas is drawn in through the valve due to decreased pressure. The reciprocating motion is achieved through transmission components such as the crankshaft, connecting rod, eccentric slider, and swashplate.

[0003] Filter devices are typically used in compressors to ensure the stability of the compression system and the quality of the gas. Their core functions include impurity interception, gas purification, and noise reduction. In industrial production, filter devices prevent contaminants such as dust and metal shavings from entering the compressor cylinder through physical interception (such as metal mesh or filter element) or chemical adsorption (such as activated carbon), thus avoiding malfunctions such as valve wear and piston scoring.

[0004] Currently, the filtration devices used in compressors are located on the cover of the compressor's drive motor. These devices penetrate the exhaust chamber to filter condensate vapors inside the compressor. However, this configuration results in a longer compressor, increasing its size and hindering efficient gas purification. Furthermore, impurities accumulate inside the filtration device, affecting the filtration rate and effectiveness. Therefore, it is necessary to design a compact, self-cleaning, distributed compressor filtration device. Utility Model Content

[0005] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a distributed and compact compressor high-efficiency filtration device, which realizes the distributed structure setting of the filtration device, and has the purpose of being compact and automatically cleanable.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A distributed and compact compressor high-efficiency filtration device includes filter cartridges mounted on the compressor cover. The filter cartridges penetrate the exhaust chamber inside the compressor body. The filter cartridges are arranged in multiple sets and are evenly distributed on the compressor cover. Each filter cartridge includes a support box that penetrates the compressor cover. A filter screen is fitted inside the support box. The end of the filter screen is provided with an installation end that connects to the compressor cover, for high-efficiency distributed filtration of the filtration device.

[0008] Preferably, the support box is rotatably provided with an automatic cleaning component that penetrates the filter screen. One side of the automatic cleaning component is provided with a cleaning end that fits against the support box and the filter screen, and the other side of the automatic cleaning component is provided with a force-receiving blade that drives the cleaning end for cleaning the filter device.

[0009] Preferably, the automatic cleaning component includes a positioning bearing connected to the support box, a central shaft rotatably mounted in the middle of the positioning bearing, and crossbars respectively connected to the force-bearing blade and the cleaning end on the central shaft, with the force-bearing blade and the cleaning end located on opposite sides of the force-bearing blade, thereby increasing the rotational stability of the automatic cleaning component.

[0010] Preferably, the cleaning end includes a cleaning pad that is between and in contact with the support box and the filter screen. The cleaning pad is vertically connected to the crossbar and is made of nylon. The crossbar is provided with an adhesive plate that is in contact with the inner wall of the filter screen. A flexible pad is provided on the side of the adhesive plate near the filter screen. An assisting ball is rotatably provided on the side of the flexible pad near the filter screen. The flexible pad is made of rubber.

[0011] Preferably, a limiting bracket is provided between the filter screen and the installation end, and the limiting bracket has a slot for the filter screen to pass through. The inner wall of the slot is provided with an outer fitting pad and an inner fitting pad that fit with the filter screen.

[0012] Preferably, both the outer and inner bonding pads are arc-shaped to increase the sealing of the connection between the filter and the support box.

[0013] Preferably, the end of the support box is provided with a connecting end, and the connecting end and the mounting end are provided with the same riveting end, and the riveting end is connected to the machine cover for the installation of the filter device.

[0014] Compared with existing technologies, the high-efficiency filtration device for compressors provided by this utility model features a distributed structure during compression, resulting in a compact structure that enables efficient filtration and automatic cleaning. Specifically, a single long cylindrical filter is replaced by multiple short-sized support cylinders evenly distributed on the compressor cover. This allows for a larger contact area between the air and the filter, enabling the handling of large-flow exhaust gas with uniform processing. This extends the filter's lifespan within the compressor, reduces its space requirements, simplifies its structure, and achieves highly efficient filtration.

[0015] Furthermore, the automatic cleaning component in the filter cartridge enhances its structural strength by being internally located, allowing for the differentiation and filtration of impurities, thus improving filtration efficiency. It is also easy to install in compressors and highly adaptable. Simultaneously, the placement of the force-bearing blades allows the filter to utilize the kinetic energy of flowing air to rotate the blades, cleaning the surfaces of the filter screen and support cylinder. This automatic cleaning extends the filter's lifespan and is highly beneficial for efficient filtration in compressors.

[0016] It should be understood that the general descriptions and details herein are exemplary and illustrative only and are not intended to limit this disclosure.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0028] As attached Figure 1 To be continued Figure 7 As shown, the embodiment of this utility model provides a distributed and compact high-efficiency filtration device for compressors. Currently, compressors used in industry have filter cartridges 3 installed on the cover 2 of the drive motor to filter impurities in the condensate exhaust chamber inside the compressor body 1. The filter cartridge 3 penetrates the exhaust chamber inside the compressor body 1. When the compressor is in use, the internal gas enters the filter cartridge 3, and impurities are filtered onto the filter cartridge 3. After passing through the filter cartridge 3, the gas enters the exhaust chamber inside the compressor for cooling. The filter cartridge 3 achieves physical filtration. To improve the space occupied by the filtration device in the compressor and reduce the compressor volume, the number of filter cartridges 3 can be set to multiple sets. Multiple sets of filter cartridges 3 are evenly distributed on the cover 2, and the filter cartridge 3 uses a support box 4 with a length shorter than that of the existing filter cartridge 3. The support box 4 is not connected to the stator in the motor (e.g., Figure 2As shown in the diagram (for reference only), a support box 4 is used as a stable structure for the filter cylinder 3, and one end of the support box 4 penetrates through the cover 2. Then, a filter screen 5 is installed inside the support box 4. An installation end 9 connected to the cover 2 is provided at the end of the filter screen 5. The installation end 9, together with the support box 4, can install the filter screen 5 on the cover 2 and fix it, thus determining the usage position of the filter device, realizing distributed filtration of the filter device in the compressor, and improving the filtration efficiency of impurities inside the compressor.

[0029] It is worth noting that, in order to ensure the long-term use of the filtration device, such as... Figure 4 and 5 As shown, in some embodiments, an automatic cleaning component 12 that penetrates the filter screen 5 can be rotatably mounted on the support box 4, and an automatic cleaning structure can be added to the filter cylinder 3. A cleaning end 16 is provided on one side of the automatic cleaning component 12, and the cleaning part of the cleaning end 16 is in contact with the support box 4 and the filter screen 5. Then, a force-receiving blade 15 that can drive the cleaning end 16 is provided on the other side of the automatic cleaning component 12. When the cleaning component 12 is rotated, the force-receiving blade 15 can use the kinetic energy of the air introduced into the filter cylinder 3 to drive the cleaning end 16 to rotate on the filter screen 5. Through the friction between the cleaning end 16 and the filter screen 5 and the support box 4, the filter device can be automatically cleaned.

[0030] To achieve automatic cleaning of the automatic cleaning component 12, such as Figure 5 and 6 As shown, in some embodiments, the automatic cleaning component 12 may use a positioning bearing 21 connected to the support box 4 as a rotatable connecting end 10. A central shaft 13 is rotatably arranged in the middle of the positioning bearing 21, and a crossbar 14 is provided on the central shaft 13, which is connected to the force-bearing blade 15 and the cleaning end 16 respectively. The force-bearing blade 15 and the cleaning end 16 are located on both sides of the force-bearing blade 15, so that the force-bearing blade 15 and the cleaning end 16 are balanced on the central shaft 13, which increases the rotational stability of the automatic cleaning component 12, ensures that the force-bearing blade 15 drives the cleaning end 16 smoothly, and provides favorable conditions for the cleaning end 16 to clean the filter screen 5.

[0031] like Figure 7As shown, the cleaning end 16 includes a cleaning pad 17 located between the support box 4 and the filter screen 5. The cleaning pad 17 is attached to both the support box 4 and the filter screen 5, and is vertically connected to the crossbar 14. When the automatic cleaning component 12 is in use, the force-bearing blade 15 is first subjected to force and rotates around the central axis 13, so that the crossbar 14 can drive the cleaning pad 17 to rub against the filter screen 5 and the support box, thus preventing impurities from being retained. In some embodiments, the cleaning pad 17 can be made of nylon material. Furthermore, an adhesive plate that adheres to the inner wall of the filter screen 5 can also be provided on the crossbar 14. 18. Then, a flexible pad 19 is provided on the side of the bonding plate 18 near the filter screen 5. The flexible pad 19 can be made of rubber material. Next, an assisting ball 20 is rotatably provided on the side of the flexible pad 19 near the filter screen 5. The assisting ball 20 can fit with the surface of the filter screen 5. The rotation of the ball in the flexible pad 19 can facilitate the movement of the cleaning end 16. In some embodiments, the cleaning pad 17 and the bonding plate 18 can be cleaning brushes made of nylon material. The roughness of the cleaning brush surface can be used to fit with the impurities over a larger area, thereby causing the impurities to separate from the filter screen 5.

[0032] To facilitate the connection of filter screen 5 in the support cylinder, such as Figure 4 As shown, in some embodiments, a limiting bracket 6 can be provided between the filter screen 5 and the mounting end 9. The limiting bracket 6 has a slot for the filter screen 5 to pass through. An outer fitting pad 7 and an inner fitting pad 8 are provided on the inner wall of the slot to fit the filter screen 5. By simultaneously squeezing the filter screen 5 with the inner fitting pad 8 and the outer fitting pad 7, the filter screen 5 can be vertically sleeved on the support cylinder for use, which facilitates the installation and removal of the filter screen 5 on the filter device.

[0033] Secondly, both the outer bonding pad 7 and the inner bonding pad 8 can be made of rubber material, and both can be in the shape of an arc structure. The two structures can be distributed relative to each other. By setting the shape and position of the two structural materials, the filter screen 5 and the support box 4 can be connected more tightly, increasing the sealing of the connection between the filter screen 5 and the support box 4.

[0034] Finally, as Figure 4 and 5 As shown, when the filter device is installed on the cover 2, a connecting end 10 can be provided at the end of the support box 4. By providing the same riveting end 11 through the connecting end 10 and the mounting end 9, the filter device can be easily connected to the mounting end 9, the connecting end 10 and the cover 2 using the riveting end 11, and is firmly installed on the cover 2, thus completing the firm installation of the filter device on the compressor.

[0035] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
