Description

Technical Field

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

[0002] A refrigerated air dryer is a type of compressed air post-processing equipment, mainly used to remove moisture from compressed air. It uses refrigeration technology to condense water vapor in the air into liquid water and discharge it, thereby providing dry compressed air.

[0003] The air intake pipe of the existing refrigerated dryer is fixed with a filter screen by bolts to reduce dust from entering the machine. After a period of use, a lot of dust will accumulate on the filter screen. At this time, the filter screen needs to be removed for cleaning. However, disassembly requires unscrewing each bolt one by one. This process is tedious and time-consuming, which seriously affects the efficiency of removing the filter screen. Utility Model Content

[0004] The purpose of this application is to provide a refrigerated dryer for improving the efficiency of removing the first filter screen.

[0005] This application provides a refrigerated dryer with the following technical solution: it includes a body, the body being connected to an air inlet pipe, an air outlet pipe, a fan, and a condenser assembly. The fan is used to drive the air at the air inlet pipe through the condenser assembly and out through the air outlet pipe. The air inlet pipe includes a main pipe connected to the body and a fixed pipe threadedly connected to the main pipe. The fixed pipe is provided with a first threaded end, and the main pipe is provided with a first threaded groove. The first threaded groove is used to thread-fit with the first threaded end. A first mounting ring is installed in the first threaded groove, and a first filter screen is connected to the inner ring of the first mounting ring. When the fixed pipe is threadedly connected to the main pipe, the first mounting ring is clamped by the fixed pipe and the main pipe.

[0006] By adopting the above technical solution, when it is necessary to disassemble the first filter screen, the fixing tube is rotated to remove it from the main tube, exposing the first filter screen, which can then be removed from the main tube. This is more convenient and improves the efficiency of disassembling the first filter screen compared to unscrewing each bolt one by one.

[0007] Optionally, the first mounting ring is provided with a limiting block, and the main pipe is provided with a limiting groove. The limiting groove is used to cooperate with the limiting block, and the limiting groove is connected to the first threaded groove.

[0008] By adopting the above technical solution, the limiting block is inserted into the limiting groove, and the outer surface of the limiting block is in contact with the inner wall of the limiting groove. The inner wall of the limiting groove restricts the rotation of the limiting block, that is, restricts the rotation of the first mounting ring and the first filter screen, thereby improving the stability of the first mounting ring and the first filter screen installed on the main pipe.

[0009] Optionally, a sealing ring is connected to the first threaded end, the sealing ring surrounding the outlet of the fixed tube, the sealing ring being used to seal the gap between the first threaded end and the first mounting ring.

[0010] By adopting the above technical solution, when the fixed pipe thread is connected to the main pipe, the first thread end and the first mounting ring clamp the sealing ring. The sealing ring is compressed and undergoes elastic deformation and maintains the tendency of elastic reset. The sealing ring seals the gap between the first thread end and the first mounting ring, reducing the amount of dust passing through the gap between the first thread end and the first mounting ring, and improving the dust filtration effect.

[0011] Optionally, the first threaded end is provided with an annular groove, which surrounds the outlet of the fixed tube and is used to mate with the sealing ring.

[0012] By adopting the above technical solution, the sealing ring is inserted into the annular groove, and the outer surface of the sealing ring is in contact with the inner wall of the annular groove. The inner wall of the annular groove restricts the movement of the sealing ring, thereby improving the stability of the sealing ring installed on the first threaded end.

[0013] Optionally, the main tube is connected to a second filter screen, the second filter screen having a smaller pore size than the first filter screen, and the second filter screen is located between the first filter screen and the body.

[0014] By adopting the above technical solution, the first and second filters can achieve multi-stage filtration, further reducing dust entering the machine body and improving the air cleanliness of the refrigerated dryer.

[0015] Optionally, the main pipe includes a first pipe and a second pipe threadedly connected to the first pipe. The first threaded groove is provided on the first pipe, the first pipe is provided with a second threaded end, and the second pipe is provided with a second threaded groove. The second threaded groove is used to thread into the second threaded end. A second mounting ring is installed in the second threaded groove, and the second filter screen is connected to the inner ring of the second mounting ring. When the first pipe is threadedly connected to the second pipe, the second mounting ring is clamped by the first pipe and the second pipe.

[0016] By adopting the above technical solution, when the second filter screen needs to be cleaned, rotating the first tube causes both the first tube and the fixed tube to simultaneously detach from the second tube, exposing the second filter screen, which can then be easily removed from the second tube. When installing the second filter screen, inserting the second mounting ring into the second threaded groove, and then rotating the first tube, causes the second mounting ring to be clamped again by the second tube and the first tube, thus achieving the installation of the second filter screen.

[0017] Optionally, the thread direction of the fixing tube is opposite to that of the first tube and the thread direction of the first tube is opposite to that of the second tube.

[0018] By adopting the above technical solution, when disassembling the fixed pipe, the situation where the first pipe is accidentally loosened due to the same thread direction can be avoided, thereby improving the stability of the connection between the first pipe and the second pipe.

[0019] Optionally, the main pipe is connected to an activated carbon plate, and the second filter screen is located between the first filter screen and the activated carbon plate.

[0020] By adopting the above technical solution, the activated carbon plate absorbs moisture and odors at the air inlet duct, thus better purifying the air entering the machine.

[0021] Optionally, the main tube further includes a third tube connected to the machine body. The second tube is provided with a third threaded end and a third threaded groove. The third threaded groove is used to thread into the third threaded end. A third mounting ring is installed in the third threaded groove. The activated carbon plate is connected to the inner ring of the third mounting ring. When the second tube is threaded onto the third tube, the third mounting ring is clamped by the second tube and the third tube.

[0022] By adopting the above technical solution, when the activated carbon plate needs to be replaced, rotating the second tube causes the second tube, first tube, and fixing tube to simultaneously detach from the third tube, exposing the activated carbon plate, which can then be easily removed from the third tube. When installing the activated carbon plate, the third mounting ring is inserted into the third threaded groove, and then the second tube is rotated, causing the third mounting ring to be clamped again by the third and second tubes, thus achieving the installation of the activated carbon plate.

[0023] Optionally, the thread directions of the first tube and the second tube are opposite to the thread directions of the second tube and the third tube.

[0024] By adopting the above technical solution, the first pipe and the second pipe, as well as the second pipe and the third pipe, can be disassembled or installed without interference, thereby improving the efficiency of disassembling each part of the main pipe.

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

[0026] 1. When it is necessary to disassemble the first filter screen, rotate the fixing tube to remove it from the main tube, and the first filter screen will be exposed. The first filter screen can then be removed from the main tube, which is more convenient and improves the efficiency of disassembling the first filter screen compared to unscrewing each bolt one by one.

[0027] 2. When disassembling the fixing pipe, it can avoid the situation where the first pipe is accidentally loosened due to the same thread direction, thus improving the stability of the connection between the first and second pipes. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0035] This application discloses a refrigerated dryer.

[0036] Combination Figure 1 and Figure 2 As shown, the device includes a body 1 with a cavity 11. The body 1 is connected to an air inlet pipe 2, an air outlet pipe 12, a connecting pipe 13, a fan 14, and a condenser assembly 15. The air inlet pipe 2 and the air outlet pipe 12 are respectively connected to both ends of the connecting pipe 13. The fan 14 is located at the air outlet pipe 12. The condenser assembly 15 is installed inside the connecting pipe 13. (The condenser assembly 15 is prior art, with the same structure as the heat exchange component in publication number CN215113554U, and its function is to cool the air drawn into the connecting pipe 13). When the fan 14 is started, it draws outside air through the air inlet pipe 2 into the connecting pipe 13, where it is cooled by the condenser assembly 15. The cooled air is then discharged from the air outlet pipe 12.

[0037] Combination Figure 3 , Figure 4 and Figure 5 As shown, the air inlet pipe 2 includes a main pipe 21 and a fixed pipe 22. The main pipe 21 includes a third pipe 211 fixedly connected to the body 1, a second pipe 212 threadedly connected to the third pipe 211, and a first pipe 213 threadedly connected to the second pipe 212. The fixed pipe 22 is threadedly connected to the first pipe 213. The second pipe 212 is located between the first pipe 213 and the third pipe 211. The first pipe 213 is located between the second pipe 212 and the fixed pipe 22. The fixed pipe 22 has a first threaded end 221 near the first pipe 213. The first pipe 213 has a first threaded groove 2131, which is threadedly engaged with the first threaded end 221. A first mounting ring 3 is installed in the first threaded groove 2131. A first filter screen 31 is fixedly connected to the inner ring of the first mounting ring 3. When the fixed pipe 22 is threadedly connected to the first pipe 213, the first mounting ring 3 is clamped by the fixed pipe 22 and the first pipe 213. A sealing ring 4 is connected to the side of the first threaded end 221 away from the fixed tube 22. The first threaded end 221 has an annular groove 222, which mates with the sealing ring 4. The sealing ring 4 surrounds the outlet of the fixed tube 22. When the fixed tube 22 is threaded onto the first tube 213, the sealing ring 4 abuts against the first mounting ring 3 and undergoes elastic deformation. The sealing ring 4 seals the gap between the first threaded end 221 and the first mounting ring 3, reducing the amount of dust entering the machine body 1 through the gap between the first threaded end 221 and the first mounting ring 3. In other embodiments, a limiting block 32 is provided on the outer circumferential surface of the first mounting ring 3. The limiting block 32 is integrally formed with the first mounting ring 3. The first tube 213 has a limiting groove 2132, which communicates with the first threaded groove 2131. The limiting groove 2132 is used to mate with the limiting block 32.

[0038] Combination Figure 4 and Figure 5 As shown, the first pipe 213 has a second threaded end 2133 on the side near the second pipe 212. The second pipe 212 has a second threaded groove 2121 for threaded engagement with the second threaded end 2133. A second mounting ring 5 is installed inside the second threaded groove 2121. A second filter screen 51 is fixedly connected to the inner wall of the second mounting ring 5. The aperture of the second filter screen 51 is smaller than that of the first filter screen 31. The second filter screen 51 is located between the first filter screen 31 and the body 1. When the first pipe 213 is threaded onto the second pipe 212, the second mounting ring 5 is clamped by the first pipe 213 and the second pipe 212. The thread direction of the second pipe 212 and the first pipe 213 is opposite to the thread direction of the fixed pipe 22 and the first pipe 213.

[0039] Combination Figure 4 and Figure 5As shown, the second tube 212 has a third threaded end 2122 on the side near the third tube 211, and the third tube 211 has a third threaded groove 2111. The third threaded groove 2111 is used to thread with the second threaded end 2133. A third mounting ring 6 is installed in the third threaded groove 2111. An activated carbon plate 61 is fixedly connected to the inner ring of the third mounting ring 6. The second filter screen 51 is located between the first filter screen 31 and the activated carbon plate 61. When the second tube 212 is threadedly connected to the third tube 211, the third mounting ring 6 is clamped by the second tube 212 and the third tube 211. The thread direction of the second tube 212 and the third tube 211 is opposite to that of the first tube 213 and the second tube 212. The thread direction of the second tube 212 and the third tube 211 is the same as that of the fixed tube 22 and the first tube 213. During the removal of the fixed tube 22, even if the second tube 212 and the third tube 211 become loose, the activated carbon plate 61 can be replaced at the same time as the first filter screen 31 is replaced.

[0040] The implementation principle of a refrigerated dryer according to an embodiment of this application is as follows:

[0041] When it is necessary to disassemble the first filter screen 31, rotate the fixing tube 22 so that the fixing tube 22 is removed from the first tube 213, and the first filter screen 31 is exposed. The first filter screen 31 can then be removed from the first tube 213, which is more convenient and improves the efficiency of disassembling the first filter screen 31 compared to unscrewing each bolt one by one.

[0042] 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.
