Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, specifically to an air compressor drying and filtering device. Background Technology

[0002] Air compressors are similar in structure to water pumps, compressing gas by continuously supplying air to an air tank. However, during the compression process, moisture in the air is also compressed, causing condensation when the compressed air enters the lower-temperature downstream pipes, affecting equipment operation. Air entering the compressor is typically filtered using a filter with an activated carbon layer. This not only adsorbs moisture but also removes particulate matter and other impurities. However, these filters generally need to be replaced after a certain period of use. Otherwise, dust and moisture remaining inside the filter after filtration can easily clog it, hindering airflow and causing inconvenience. Regular cleaning is also necessary; excessive moisture absorption can shorten the filter's lifespan. Currently, most filter replacement and cleaning are done manually, which is inefficient and inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide an air compressor drying and filtering device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An air compressor drying and filtering device includes:

[0006] The system comprises a base frame, an adjustment mechanism, and two fixing mechanisms. A base plate is fixedly connected between the two opposite inner sidewalls of the base frame. The adjustment mechanism is located above the base frame and includes a connecting cylinder. The bottom end of the connecting cylinder is fixedly connected to the center of the top surface of the base plate. A rotating plate is rotatably connected to the top end of the connecting cylinder. Multiple cylinders are evenly arranged outside the connecting cylinder, and support arms are fixedly connected between the outer sidewalls of the multiple cylinders and the outer sidewalls of the rotating plate. A filter element is movably inserted into the interior of each cylinder. A stepper motor is installed inside the cylinder, and the motor shaft of the stepper motor is fixedly connected to the center of the bottom surface of the rotating plate. The two fixing mechanisms are respectively fixedly connected to the two short sides of the top surface of the base frame.

[0007] Furthermore, each filter element has a rubber ring fixedly fitted to its top and bottom sides on its outer side wall, and one of the rubber rings on each filter element has multiple air outlet holes on one side.

[0008] Furthermore, multiple cuts are provided on the outer wall of each rubber ring.

[0009] Furthermore, the fixing mechanism includes:

[0010] The slide rail and two clamping plates are provided. The bottom end of the slide rail is fixedly connected to the top surface of the bottom frame. A slider is fixedly connected to one side of each of the two clamping plates. Both sliders are slidably engaged inside the slide rail. A circular hole is opened in the center of each adjacent side of the two clamping plates. A connecting pipe is fixedly connected to the inner wall of the circular hole on the upper clamping plate, and an annular cover is fixedly fitted to the inner wall of the circular hole on the lower clamping plate. One connecting pipe is connected to the air inlet of the air compressor.

[0011] Furthermore, the two clamping plates on the same fixing mechanism are both fixedly connected to retaining rings on adjacent sides.

[0012] Furthermore, each of the two fixed mechanisms has a movable plate on one side of the slide rail, and each of the two movable plates has two sliding holes on one side. Each of the two slide rails has a U-shaped rod fixedly connected to one side. The two arms of any U-shaped rod are slidably sleeved with the two sliding holes on the adjacent movable plate. Each of the two U-shaped rods has a cylinder fixedly connected to one inner wall. The movable end of any cylinder is fixedly connected to one side of the adjacent movable plate. Each of the two slide rails has two sliding grooves on one side. One end of each of the two sliders in any slide rail passes through the two adjacent sliding grooves. Each of the two movable plates has a support rod rotatably connected to both ends. One end of each of the two support rods on any movable plate is rotatably connected to one end of each of the two adjacent sliders.

[0013] Furthermore, one end of another connecting pipe is equipped with a bellows box, and the bellows box contains a fan and an electric heating wire.

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

[0015] By connecting one connecting pipe to the air compressor inlet and the other connecting pipe to the air box, two cylinders are automatically started, driving two moving plates to move. The two moving plates move two adjacent clamping plates away from each other via adjacent support rods. Then, a stepper motor is automatically started, driving a rotating plate to rotate. The rotating plate drives multiple cylinders to rotate around the circumference of the rotating plate via support arms, aligning two of the cylinders with two fixed mechanisms. Then, the cylinders are automatically started and reset, causing the two moving plates to move the adjacent clamping plates back to their original positions. The top and bottom ends of the cylinders at the two fixed mechanisms are blocked by the two adjacent clamping plates. Air from one fixed mechanism enters through the filter element opening inside the cylinder, is filtered by the filter element, and is discharged from the air outlet on the upper rubber ring, and is delivered to the air compressor through the connecting pipe. The filter element at the other fixed mechanism can be cleaned and dried by the airflow backflow through the fan and electric heating wire inside the automatically started air box. This allows for automatic filter element replacement and automatic cleaning and drying of the used filter elements, improving their service life. Attached Figure Description

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 Figures 1-4 In this embodiment of the invention, the air compressor drying and filtering device includes:

[0023] The system comprises a base frame 100, an adjustment mechanism 200, and two fixing mechanisms 400. A base plate 110 is fixedly connected between two opposing inner sidewalls of the base frame 100. The adjustment mechanism 200 is located above the base frame 100 and includes a connecting cylinder 210. The bottom end of the connecting cylinder 210 is fixedly connected to the center of the top surface of the base plate 110. A rotating plate 220 is rotatably connected to the top of the connecting cylinder 210. Multiple cylinders 230 are evenly arranged outside the connecting cylinder 210, and a support arm 221 is fixedly connected between the outer sidewall of the multiple cylinders 230 and the outer sidewall of the rotating plate 220. A filter element 240 is movably inserted inside any cylinder 230. A stepper motor is installed inside the cylinder 230, and the motor shaft of the stepper motor is fixedly connected to the center of the bottom surface of the rotating plate 220. The two fixing mechanisms 400 are fixedly connected to the two short sides of the top surface of the base frame 100, respectively.

[0024] Specifically, the filter element 240 has an activated carbon interlayer inside. The activated carbon can adsorb moisture and particulate matter in the air, thereby filtering and drying the air entering the air compressor. In use, the filter element 240 in the multiple cylinders 230 can be filtered and dried by the two fixing mechanisms 400. The user can start the stepper motor to drive the rotating plate 220 to rotate, so that the rotating plate 220 drives the multiple cylinders 230 to move around the rotating plate 220 through the support arm 221. The position of the multiple cylinders 230 can be adjusted to replace the filter element 240 located at the two fixing mechanisms 400. Thus, the filter element 240 that filters and dries the air compressor can be automatically replaced after working for a certain period of time, which is convenient for the user.

[0025] Example 1

[0026] like Figures 2-3 As shown, in this embodiment, a rubber ring 241 is fixedly sleeved on the top and bottom of the outer side wall of any filter element 240. A plurality of air outlet holes 242 are opened on one side of one of the rubber rings 241 on any filter element 240, and a plurality of cutting slits 243 are opened on the outer side wall of any rubber ring 241.

[0027] In this embodiment, when the filter element 240 is inserted into the cylinder 230, the filter element 240 is inserted into the cylinder 230 with the opening facing downwards. The filter element 240 can be held in place inside the cylinder 230 by two rubber rings 241. When the filter element 240 is inserted, the cut slits 243 on the rubber rings 241 facilitate the compression and contraction of the rubber rings 241, making it easy for the user to replace the filter element 240 inside the cylinder 230. When air enters the filter element 240 through the opening, it can be filtered by the filter element 240 and then discharged from the air outlet 242 on the top rubber ring 241 of the filter element 240 inside the cylinder 230.

[0028] like Figures 1-4 As shown, in this embodiment, the fixing mechanism 400 includes:

[0029] The slide rail 410 and two clamping plates 420 are provided. The bottom end of the slide rail 410 is fixedly connected to the top surface of the base frame 100. Each of the two clamping plates 420 has a slider fixedly connected to one side. Both sliders are slidably engaged inside the slide rail 410. A circular hole is opened at the center of each adjacent side of the two clamping plates 420. A connecting pipe 423 is fixedly connected to the inner wall of the circular hole on the upper clamping plate 420, and an annular cover 422 is fixedly fitted to the inner wall of the circular hole on the lower clamping plate 420. One connecting pipe 423 is connected to the air inlet of the air compressor. A retaining ring 421 is fixedly connected to each adjacent side of the two clamping plates 420 on the same fixing mechanism 400. A sliding plate is provided on one side of each slide rail 410 on both fixing mechanisms 400. The moving plate 430 has two sliding holes on one side. The two slide rails 410 are fixedly connected to one side of a U-shaped rod 440. The two arms of any U-shaped rod 440 are slidably sleeved with the two sliding holes on the adjacent moving plate 430. A cylinder 441 is fixedly connected to one inner wall of any U-shaped rod 440. The movable end of any cylinder 441 is fixedly connected to one side of the adjacent moving plate 430. The two slide rails 410 have two sliding grooves on one side. One end of each of the two sliders in any slide rail 410 passes through the two adjacent sliding grooves. The two ends of the two moving plates 430 are rotatably connected to support rods 431. One end of each of the two support rods 431 on any moving plate 430 is rotatably connected to one end of each of the two adjacent sliders.

[0030] In practice, when the rotating plate 220 rotates, two cylinders 441 can be activated to simultaneously push the adjacent moving plates 430 to move. This causes the two moving plates 430 to move in opposite directions via adjacent support rods 431, thus preventing the clamping plates 420 from affecting the rotation of multiple cylinders 230. When the rotating plate 220 stops rotating, the two cylinders 441 are activated to reset the two moving plates 430. This causes the two moving plates 430 to move in opposite directions via adjacent support rods 431, resulting in the two clamping plates 420 on the same fixed mechanism 400 contacting the top and bottom ends of the adjacent cylinders 230. This causes the annular cover 422 to seal the bottom end of the adjacent cylinders 230, and the connecting pipe 423 to seal the top end of the adjacent cylinders 230. A connecting pipe 423 is connected to the air inlet of the air compressor, allowing the dried and filtered air to enter the air compressor and be compressed. The annular cover 422 is made of rubber and can be sealed against the filter element 240, so that air can only enter the cylinder 230 from the opening of the filter element 240. This prevents air from easily entering the cylinder 230 from the cut 243 on the rubber ring 241 at the bottom of the filter element 240. When the two clamps 420 on the same fixing mechanism 400 abut against the top and bottom ends of the adjacent cylinder 230, the cylinder 230 can be locked into the retaining ring 421 on the two clamps 420, preventing air from entering the cylinder 230 from the gap between the clamps 421 and the cylinder 230. The retaining ring 421 is made of rubber.

[0031] Example 2

[0032] Based on Example 1, the filter element 240 can be backwashed by setting up the air box 300, thereby improving the service life of the filter element 240.

[0033] like Figure 1 As shown, in this embodiment, one end of another connecting pipe 423 is provided with a wind box 300, and the wind box 300 is provided with a fan and an electric heating wire.

[0034] In specific implementation, another connecting pipe 423 is connected to the air box 300. When the filter element 240 is connected to the other connecting pipe 423, the fan in the other connecting pipe 423 can be started, allowing cold air to enter the cylinder 230 and blow out from the opening of the filter element 240, thereby backwashing the filter element 240 to a certain extent, which facilitates cleaning the filter element 240. The electric heating wire on the fan can also be started to blow out hot air to dry the activated carbon layer inside the filter element 240 that has adsorbed moisture, thereby cleaning and drying the filter element 240 and improving its service life. In use, the stepper motor, two cylinders 441, fan and electric heating wire can be controlled by multiple controllers to automatically adjust the position of multiple cylinders 230 through program control and automatically clean and dry the filter element.

[0035] Stepper motors, electric heating wires, fans, etc. are all existing technologies and will not be described in detail here.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
