Description

Technical Field

[0001] This application relates to the technical field of refrigerated dryers, and more particularly to a refrigerated dryer for compressors. Background Technology

[0002] Refrigerated air dryers for compressors are key equipment in compressed air after-treatment systems. They are mainly used to remove moisture from compressed air and ensure that the air is dry and clean.

[0003] The machine contains a fan that dissipates heat from the heat sink. To reduce dust entering the machine, a filter is typically installed at the air intake. After prolonged use, the filter accumulates a large amount of dust, affecting its filtration efficiency. Wiping the filter directly only cleans the outer surface and not the inner side. Therefore, the filter needs to be removed from the machine for cleaning. However, since the filter is bolted to the machine, removing it is somewhat cumbersome and needs improvement. Utility Model Content

[0004] The purpose of this application is to provide a refrigerated dryer for compressors, which facilitates the removal of the filter from the machine body.

[0005] This application provides a compressor-type refrigerated dryer with the following technical solution: It includes a body, the body having a receiving cavity, a refrigeration system connected within the receiving cavity, an air outlet channel and an air inlet channel communicating with the receiving cavity, a heat dissipation plate connected to the body, the heat dissipation plate covering the air outlet channel, and a plurality of heat dissipation holes. The body is characterized by a detachably connected filter plate, the filter plate having an installation channel, a filter screen connected within the installation channel, an installation groove communicating with the air inlet channel, the installation groove for the filter plate to engage, the filter plate covering the air inlet channel, and a handle on one side of the filter plate.

[0006] By adopting the above technical solution, when it is necessary to clean the impurities on the filter screen, the filter plate is lifted by the handle, and the filter screen passes through the mounting groove and detaches from the machine body along with the filter plate. Compared with loosening the filter screen with bolts and then removing the filter screen from the machine body, the method of removing the filter screen in this application is more convenient. After the filter screen is cleaned, the filter plate is inserted into the mounting groove. The outer surface of the filter plate fits against the inner wall of the mounting groove, and the filter plate can be installed on the machine body under the influence of gravity, resulting in fast installation efficiency.

[0007] Optionally, the three inner walls of the mounting groove and the one side wall of the mounting groove that penetrates the body surround the opening of the air inlet channel.

[0008] By adopting the above technical solution, the contact area between the inner wall of the mounting groove and the filter plate is increased, which increases the movement path of dust and reduces the amount of dust entering the machine body through the gap between the filter plate and the machine body. This reduces the amount of dust adhering to the components inside the machine body and protects the components inside the machine body.

[0009] Optionally, the filter plate is slidably connected to two fixed rods, and the filter plate is connected to a linkage assembly. The linkage assembly is used to drive the two fixed rods to slide towards each other or away from each other. The machine body is provided with two fixed slots that communicate with the mounting slot. The fixed slots correspond one-to-one with the fixed rods, and the fixed slots are used to cooperate with the fixed rods.

[0010] By adopting the above technical solution, when the filter plate is installed on the machine body, the fixing rod is engaged in the fixing groove, and the outer surface of the fixing rod fits against the inner wall of the fixing groove. The inner wall of the fixing groove restricts the movement of the fixing rod, thus preventing the filter plate from detaching from the mounting groove and improving the stability of the filter plate installed on the machine body. When it is necessary to clean the impurities on the filter screen, the linkage component drives the two fixing rods to slide away from each other, causing the fixing rods to disengage from the fixing groove. The filter plate and filter screen can then be lifted out of the machine body through the handle, making it convenient to remove the filter plate from the machine body.

[0011] Optionally, the linkage component includes an elastic element and an active structure connected to the filter plate. The two ends of the elastic element are respectively connected to the opposite sides of the two fixed rods. The active structure is used to drive the two fixed rods to slide towards each other.

[0012] By adopting the above technical solution, the active structure drives the two fixed rods to slide towards each other. The elastic element is compressed and undergoes elastic deformation and maintains the tendency of elastic reset. When the active structure no longer applies force to the two fixed rods, the elastic element elastically resets and forces the two fixed rods to slide away from each other, thereby realizing that the fixed rods are inserted into or released from the fixing groove.

[0013] Optionally, the active structure includes a passive rod disposed on each of the fixed rods and an active block slidably connected to the filter plate. The active block is provided with a clearance groove on the side near the passive rod. Both passive rods are provided with inclined surfaces on opposite sides. The inclined surfaces are located at the ends of the passive rods away from the fixed rods and are used to abut against the inner wall of the clearance groove.

[0014] By adopting the above technical solution, the active block is moved towards the passive rod, so that the inner wall of the slot abuts against the inclined surface and drives the two passive rods to move towards each other. The elastic element is compressed and produces elastic deformation and maintains the tendency of elastic reset. When the active block is moved away from the passive rod, the active block no longer applies force to the passive rod, and the elastic element elastically resets, thereby realizing the sliding of the two fixed rods towards each other or away from each other.

[0015] Optionally, the filter plate is provided with a receiving groove that extends through the handle, and the active block slides into the receiving groove.

[0016] By adopting the above technical solution, the operator can press the active block simultaneously while holding the handle, and remove the filter plate and filter screen with one hand, which is quite convenient.

[0017] Optionally, the inner wall of the receiving groove is connected to a limiting post, and the active block is provided with an oblong hole for sliding engagement with the limiting post. The extending direction of the oblong hole is the same as the moving direction of the active block.

[0018] By adopting the above technical solution, when the active block slides, the sliding cooperation between the limiting post and the waist-shaped hole plays a guiding and limiting role in the sliding of the active block, thereby improving the stability of the active block sliding and preventing the active block from leaving the receiving groove during the sliding process.

[0019] Optionally, each of the two fixed rods has a guide surface at one end that is far apart from the other, and the guide surface is used to abut against the body.

[0020] By adopting the above technical solution, during the process of inserting the mounting plate into the mounting groove, the machine body abuts against the guide surface and drives the fixing rod to slide towards the elastic element. The elastic element is compressed and maintains its elastic reset tendency until the fixing rod aligns with the fixing groove. The elastic element then elastically resets, forcing the fixing rod into the fixing groove, thereby realizing the installation of the filter plate. The mounting plate does not rely on an active block during installation, making filter plate installation relatively convenient.

[0021] Optionally, two of the filter plates are spaced apart on the shown body, the number of mounting slots is the same as the number of filter plates, the mounting slots correspond one-to-one with the filter plates, and one of the filter plates is located between the other filter plate and the receiving cavity.

[0022] By adopting the above technical solution, setting two filter plates can enhance the filtration effect on the air entering the machine, further ensuring that the air entering the machine is clean. In addition, each filter plate is detachably connected to the machine through a corresponding mounting slot, which facilitates individual cleaning of the filter plate.

[0023] Optionally, the pore size of the filter screen furthest from the receiving cavity is larger than that of the other filter screen.

[0024] By adopting the above technical solution, compressed air is filtered in multiple stages using filter screens with different pore sizes. First, larger dust particles are filtered by the large-pore filter screen, and then smaller dust particles are filtered by the small-pore filter screen, thereby improving the filtration effect.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When it is necessary to clean the impurities on the filter screen, lift the filter plate with the handle. The filter screen will pass through the mounting slot and detach from the machine body along with the filter plate. Compared with loosening the filter screen with bolts and then removing the filter screen from the machine body, the method of removing the filter screen in this application is more convenient.

[0027] 2. The operator can press the active block while holding the handle, and the filter plate and filter screen can be removed with one hand, which is quite convenient. Attached Figure Description

[0039] like Figure 2 As shown, a connecting frame 5 is provided on one side of the body 1. The connecting frame 5 is positioned opposite to the air outlet duct 12. The length, width, and height of the connecting frame 5 are designed according to actual needs. The connecting frame 5 has an air inlet duct 51, which penetrates one side wall of the body 1 and communicates with the receiving cavity 11. The size of the air inlet duct 51 is designed according to actual needs. At least two filter plates 6 are detachably connected to the connecting frame 5. Taking this embodiment as an example, there are two filter plates 6, which are spaced apart on the connecting frame 5. One filter plate 6 is located between the other filter plate 6 and the body 1. Each filter plate 6 has an installation channel 61. A filter screen 62 is fixedly connected to the inner wall of the installation channel 61. The aperture of the filter screen 62 away from the receiving cavity 11 is larger than that of the other filter screen 62.

[0040] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the connecting frame 5 has two mounting slots 52 communicating with the air inlet channel 51. Each mounting slot 52 corresponds to a filter plate 6, and the filter plate 6 can be inserted into the mounting slot 52. The mounting slot 52 extends through the upper surface of the connecting frame 5. The three inner walls of the mounting slot 52 and the upper surface of the connecting frame 5 surround the opening of the air inlet channel 51. The three inner walls of the mounting slot 52 are the bottom wall and the two side walls of the mounting slot 52. When the filter plate 6 is inserted into the mounting slot 52, the filter plate 6 covers the air inlet channel 51. The filter plate 6 is slidably connected to two fixing rods 7. The filter plate 6 has a sliding groove 63 that slides with the fixing rods 7. Each of the two fixing rods 7 has a guide surface 71 at its far end, located on the lower surface of the fixing rods 7. The connecting frame 5 has two fixing slots 53 communicating with the mounting slots 52. Each fixing slot 53 corresponds to a fixing rod 7, and the fixing slot 53 is used to engage with the fixing rod 7.

[0041] Combination Figure 5 , Figure 6 and Figure 7 As shown, the filter plate 6 is connected to a linkage assembly 8. The linkage assembly 8 is used to drive the two fixed rods 7 to slide towards or away from each other. The linkage assembly 8 includes an elastic element 81 and an active structure 82 for driving the two fixed rods 7 to slide towards each other. The elastic element 81 is a spring, and its two ends are fixedly connected to the opposite sides of the two fixed rods 7, respectively. A handle 64 is fixedly connected to the upper surface of the filter plate 6. The active structure 82 includes a passive rod 821 fixedly connected to each fixed rod 7 and an active block 822 slidably connected to the filter plate 6. The filter plate 6 has a receiving groove 65 communicating with the sliding groove 63. The receiving groove 65 passes through the handle 64. The passive rod 821 and the active block 822 are located in the receiving groove 65. A portion of the active block 822 protrudes from the handle 64.

[0043] When it is necessary to clean the impurities on the filter screen 62, hold the handle 64 and press the active block 822 with your finger. The active block 822 abuts against the inclined surface 8211 and drives the two passive rods 821 to slide towards each other, that is, the two fixed rods 7 slide towards each other. The elastic element 81 is compressed and produces elastic deformation and has the tendency to elastically return to its original position until the fixed rods 7 are disengaged from the fixed groove 53. Then the filter plate 6 and the filter screen 62 can be disengaged from the connecting frame 5 for easy disassembly.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
