[0007] The exhaust pipe has an exhaust connection pipe with an intake end welded to its outlet end, and the exhaust connection pipe is connected to the exhaust pipe. The inlet end of the return gas pipe is welded and fixed to the outlet end of the return gas connecting pipe, and the return gas connecting pipe is connected to the return gas pipe.

[0008] Both the first and second elastic connecting tubes are rubber tubes.

[0009] The insulation device is an insulation pipe, and the exhaust pipe and return pipe are inserted into the insulation pipe.

[0010] The outstanding effect of this utility model is: Compared with the prior art, 1. The exhaust pipe and the return pipe are respectively connected to the first outlet pipe and the first inlet pipe through the first elastic connecting pipe and the second elastic connecting pipe, so that during installation, the connection between the first outlet pipe and the first inlet pipe and the compressor can be guaranteed by bending the first elastic connecting pipe and the second elastic connecting pipe at any angle. 2. The elastic effect of the first and second elastic connecting pipes improves the vibration resistance of the compressor and the pipeline vibration resistance. 3. The first elastic connecting tube and its two ends are connected to the outer wall of the corresponding tube body through the aluminum sleeve, and the connection is firm and stable; 4. The exhaust pipe and return pipe are installed through the cable tray, which makes the connection between the two compact and also prevents the exhaust pipe and return pipe from shaking, thus reducing noise.

Detailed Implementation

[0012] For example, see below. Figures 1 to 5 As shown, a flexible anti-vibration pipe fitting device for drying equipment includes an exhaust pipe 10 and a return pipe 20. The outer side of the main body of the exhaust pipe 10 and the return pipe 20 is provided with a heat preservation device 30. The main bodies of the exhaust pipe 10 and the return pipe 20 are close to each other and installed in the same cable tray 40. The air inlet of the exhaust pipe 10 is connected to one end of the first elastic connecting pipe 11, the other end of the first elastic connecting pipe 11 is connected to the air outlet of the first air inlet connecting pipe 12, and the air inlet of the first air inlet connecting pipe 12 is connected to the air outlet of the compressor. The outlet end of the return pipe 20 is connected to one end of the second elastic connecting pipe 21, and the other end of the second elastic connecting pipe 21 is connected to the inlet end of the first outlet connecting pipe 22. The outlet end of the first outlet connecting pipe 22 is connected to the inlet of the compressor.

[0013] In this embodiment, the use of a first elastic connecting pipe 11 and a second elastic connecting pipe 21 allows the first air inlet connecting pipe 12 and the first air outlet connecting pipe 22 to be bent and flipped in different directions to change their orientation, making it convenient for the air inlet end of the first air inlet connecting pipe 12 to connect to the air outlet of the compressor, and the air outlet end of the first air outlet connecting pipe 22 to connect to the air inlet of the compressor.

[0014] Moreover, its first elastic connecting pipe 11 and second elastic connecting pipe 21 have good anti-vibration effect, which can reduce the vibration of the pipeline caused by the operation of the compressor and the vibration of the pipeline caused by other factors, thereby reducing noise.

[0015] Furthermore, both the exhaust pipe 10 and the return pipe 20 are copper pipes, as are the first outlet connection pipe 22 and the first inlet connection pipe 12.

[0016] The exhaust pipe 10 has its outlet end welded to the inlet end of an exhaust connecting pipe 13, which is connected to the exhaust pipe 10. The outlet end of the exhaust connecting pipe 13 is connected to the inlet of the condenser. The return pipe 20 has its inlet end welded to the outlet end of a return connecting pipe 23, which is connected to the return pipe 20. The inlet end of the return connecting pipe 23 is connected to the outlet end of the evaporator.

[0017] Both the first elastic connecting tube 11 and the second elastic connecting tube 21 are rubber tubes.

[0018] The heat preservation device 30 is a heat preservation pipe. The exhaust pipe 10 and the return pipe 20 are inserted into the heat preservation pipe. The air inlet end of the return pipe 20 and the air outlet end of the return pipe 23 are also located in the corresponding heat preservation pipe. The outer wall of the exhaust pipe 10 is close to or in close contact with the inner wall of the corresponding heat preservation pipe. The outer walls of the air outlet ends of the return pipe 20 and the return pipe 23 are close to or in close contact with the inner wall of the corresponding heat preservation pipe.

[0019] An aluminum sleeve 1 is fitted onto the outer walls of both ends of the first elastic connecting pipe 11 and the second elastic connecting pipe 21. The inner walls of both ends of the first elastic connecting pipe 11 and the second elastic connecting pipe 21 are pressed against the outer walls of the corresponding pipe bodies. That is, the inner walls of both ends of the first elastic connecting pipe 11 are pressed against the outer walls of the air inlet end of the exhaust pipe 10 and the air outlet end of the first air inlet connecting pipe 12, and the inner walls of both ends of the second elastic connecting pipe 21 are pressed against the outer walls of the air outlet end of the return pipe 20 and the air inlet end of the first air outlet connecting pipe 22.

[0020] Furthermore, the main body of the exhaust pipe 10 and the return pipe 20 is inserted into the mounting groove of the wiring trough 40, and multiple cover plates 41 are snapped and fixed on the outer side of the wiring trough 40. The main body of the exhaust pipe 10 and the return pipe 20 is located between the cover plate 41 and the inner wall of the inner side plate of the wiring trough 40.

[0021] Limiting grooves are formed on the outer wall surfaces of the two bent edges at both ends of the cable tray 40. Cable ties 2 are inserted into the corresponding two limiting grooves. One end of the insulation pipe of the exhaust pipe 10 and the return pipe 20 on the same side is fixed to the cable tray 40 by cable ties 2.

[0022] The wiring channel 40 makes the installation structure of the exhaust pipe 10 and the return pipe 20 compact, not easy to shake, and ensures a firm connection.

[0023] Furthermore, a dividing protrusion 42 is formed in the middle of the inner wall surface of the inner wall plate of the cable tray 40, and the exhaust pipe 10 and the return pipe 20 are located on both sides of the dividing protrusion 42 and are separated by the dividing protrusion 42.

[0024] The dividing protrusion 42 prevents the exhaust pipe 10 and the return pipe 20 from being too close together.

[0025] Furthermore, sensor fixing sleeves 5 are welded and fixed to the outer wall of the middle part of the first air inlet connecting pipe 12 and the first air outlet connecting pipe 22.

[0026] Furthermore, the air inlet end of the return pipe 20 and the air outlet end of the exhaust pipe 10 are formed with bent portions. The bent portions are inserted into the corresponding bent second wiring groove 50. The outer wall surfaces of both ends of the bent edge of the second wiring groove 50 are formed with slots. The second cable tie 6 is inserted into the two corresponding slots of the two bent edges and the bent portions of the return pipe 20 and the exhaust pipe 10 are fixed to the second wiring groove 50 by the second cable tie 6.

[0027] The inner wall of the inner wall plate of the second wiring trough 50 is also formed with a second partition strip in the middle, which separates the corresponding parts of the return pipe 20 and the exhaust pipe 10.

[0028] In this embodiment, the insulation pipe is a PVC pipe, but other insulation materials can also be used.

[0029] Finally, the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model.
