[0035] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0036] like Figure 1-11 As shown, an embodiment of the present invention discloses a compressed air dew point temperature monitoring system, including a refrigerated drying unit, wherein the refrigerated drying unit includes an air inlet 1 and an air outlet 2, and a monitoring unit is provided at the air outlet 2. The refrigerated drying unit also includes a compressor 3, the monitoring unit is electrically connected to a PLC control module, and the PLC control module is electrically connected to the compressor 3. The monitoring unit sends a temperature signal to the PLC control module, and the PLC control module judges and sends an action signal of the compressor 3 based on the temperature signal.

[0037] Specifically, when in use, air enters the refrigerated drying unit along the air inlet 1, the refrigerated drying unit dries the air and discharges it from the air outlet 2, the monitoring unit collects the temperature of the discharged gas at any time, and the PLC control module determines the start and stop of the compressor according to the discharged temperature.

[0038] By providing a monitoring unit at the air outlet 2, the temperature at the outlet can be collected at any time, which is convenient for starting and stopping the compressor, reducing unnecessary energy consumption, achieving the purpose of energy saving, and reducing energy consumption.

[0039] Furthermore, the monitoring unit includes a dew point meter, which is arranged in the air outlet 2.

[0040] Furthermore, the dew point meter and the PLC control unit are existing technologies and will not be described in detail.

[0041] Specifically, the dew point meter monitors the temperature of the gas discharged from the gas outlet 2 and transmits the temperature signal to the PLC control module.

[0042] like Figure 1-11 As shown, the freeze drying unit also includes a box body 4, the air inlet 1 and the air outlet 2 are located on the upper side of the box body 4, and a shock absorbing mechanism 5 is provided on the bottom surface of the box body 4, and the shock absorbing mechanism 5 includes a shock absorbing member 51, and the shock absorbing member 51 is in contact with the ground. The shock absorbing member 51 and the box body 4 are connected by a connecting member 52, and the shock absorbing member 51 includes a mounting frame 511 sleeved on the box body 4, and the mounting frame 511 is connected to the connecting member 52, and the connecting member 52 can fix the mounting frame 511 on the box body 4, and the bottom surface of the mounting frame 511 is fixedly connected to a telescopic sleeve 512, and the telescopic sleeve 512 is made of rubber material, and the lower end of the telescopic sleeve 512 is fixedly connected to an abutting frame 513, and the abutting frame 513 abuts the ground.

[0043] Specifically, during use, the connecting piece 52 keeps the installation frame 511 fixed to the box body 4. When the freeze-drying unit is placed on the ground, the abutment frame 513 first contacts the ground. Then, under the action of the gravity of the freeze-drying unit, the box body 4 drives the installation frame 511 to compress the telescopic sleeve 512, so that the telescopic sleeve 512 is pressed tightly against the abutment frame 513.

[0044] By setting the shock-absorbing member 51, when the refrigerated drying unit is placed on the ground, a flexible connection is formed between the telescopic sleeve 512 and the ground, thereby preventing the refrigerated drying unit from vibrating during operation and generating excessive noise between the refrigerated drying unit and the ground, thereby preventing the operator from being disturbed.

[0045] like Figure 1-11 As shown, a limiting member 53 is provided between the abutment frame 513 and the box body 4, and the limiting member 53 includes a fixed block 531 fixedly connected to the bottom surface of the box body 4, and four fixed rods 532 are symmetrically fixedly connected to the inner annular surface of the abutment frame 513, and a limiting spring 533 is connected between the end of each fixed rod 532 close to the fixed block 531 and the fixed block 531.

[0046] Specifically, when in use, the limiting member 53 limits the movement of the abutment frame 513 through the limiting spring 533, avoiding excessive displacement between the abutment frame 513 and the cabinet 4 when the freeze-drying unit is working, resulting in unstable support of the abutment frame 513 on the cabinet 4.

[0047] By providing the limiting member 53 , the contact frame 513 can be limited to a certain extent, thereby preventing excessive displacement between the contact frame 513 and the box body 4 , which would result in unstable support for the box body 4 .

[0048] like Figure 1-11 As shown, a detector is provided in the box 4, and the detector can detect the content of Freon in the air of the box 4. Heat dissipation mesh holes are provided on the four vertical sides of the box 4. Two moving parts 54 are symmetrically provided on the box 4, and the moving part 54 includes two slide rails 541 fixedly connected to the front and rear sides of the box 4. The slide rails 541 in the two moving parts 54 are parallel, and two slide grooves are provided on the inner annular surface of the installation frame 511. The slide rails 541 slide relatively in the slide grooves. A motor 542 is provided at the top of the box 4, and the output end of the motor 542 is fixedly connected to a winding wheel 543. Two pull ropes 544 are fixedly connected to the winding wheel 543, and the other ends of the two pull ropes 544 are respectively fixedly connected to the ends of the installation frame 511. A support member 55 is provided at the bottom of the box 4, and the support member 55 can prop up the box 4.

[0049] Furthermore, the detector is a prior art and will not be described in detail. The detector is electrically connected to the PLC control module, and the PLC control module is electrically connected to the motor 542.

[0050] Specifically, when the detector detects that the Freon content in the box 4 is too high, that is, the compressor fails, resulting in Freon leakage, the detector sends a concentration signal to the PLC control module. After the PLC control module makes a judgment on the concentration, it sends a start signal to the support member 55. The support member 55 supports the box 4. At the same time, the pressure of the box 4 is no longer borne by the abutment frame 513. Under the action of the limit member 513, the vertical axis of the abutment frame 513 is collinear with the vertical axis of the box 4. At the same time, a start signal is sent to the motor 542, and the motor 542 starts. The output end of the motor 542 drives the winding wheel 543 to rotate, and the winding wheel 543 drives the pull rope 544 to wind around the winding wheel 543. At the same time, the PLC sends a signal to the connector 52, so that the connector 52 releases the limit on the installation frame 511, and the pull rope 544 drives the installation frame 511 to move upward. The installation frame 511 drives the telescopic sleeve 512 to expand and close the heat dissipation mesh. When the telescopic sleeve 512 is stretched to the limit length, the abutment frame 513 abuts against the bottom surface of the box body 4. At this time, the installation frame 511, the telescopic sleeve 512 and the abutment frame 513 jointly close the heat dissipation mesh.

[0051] By setting the movable part 54, when Freon leakage occurs inside the freeze drying unit, the movable part 54 can drive the telescopic sleeve 54 to expand, closing the heat dissipation mesh holes on the box body 4, thereby preventing a large amount of Freon from leaking into the air and polluting the air environment; at the same time, when the cooling and drying unit has been used for a period of time and dust accumulates on the heat dissipation mesh holes, this action is repeated, so that the installation frame 511 scrapes across the heat dissipation mesh holes to clean the accumulated dust and avoid affecting the heat dissipation effect.

[0052] like Figure 1-11 As shown, two connecting parts 52 are symmetrically arranged in the box body 4, and the connecting part 52 includes an electric push rod 521 fixedly connected to the inside of the box body 4, and the output end of the electric push rod 521 is fixedly connected to a first limit plate 522, and the first limit plate 522 extends out of the box body 4. A limit frame 523 is fixedly connected to the mounting frame 511, and the first limit plate 522 can be inserted into the limit frame 523.

[0053] Furthermore, the electric push rod 521 is a prior art and will not be described in detail.

[0054] Specifically, when the installation frame 511 needs to be released from the box body 4, the PLC sends a start signal to the electric push rod 521, the output end of the electric push rod 512 contracts, and the output end of the electric push rod 512 drives the first limit plate 522 to be pulled out from the limit frame 523, thereby releasing the limit on the installation frame 511.

[0055] like Figure 1-11 As shown, the support member 55 includes four hydraulic rods 551 arranged in a matrix inside the box body 4 . The hydraulic rods 551 are fixedly connected to the box body 4 , and the output ends of the hydraulic rods 551 pass through the bottom surface of the box body 4 .

[0056] Specifically, when the box body 4 needs to be supported, the PLC sends a start signal to the hydraulic rod 551 , and the output end of the hydraulic rod 551 extends and contacts the ground to support the box body 4 .

[0057] A closing member 56 is provided between the movable member 54 and the air inlet 1 and the air outlet 2. The closing member 56 includes a sealing plate 561 provided in the box body 4. The sealing plate 561 is slidably connected to the top wall of the box body 4. Two through holes are provided on the sealing plate 561. The sealing plate 561 passes through the air inlet 1 and the air outlet 2. The two through holes are respectively connected to the air inlet 1 and the air outlet 2. A rack 562 is fixedly connected to the sealing plate 561. The output end of the motor 542 in one of the movable members 54 passes through the box body 4. A gear 563 is fixedly provided on the output end of the motor 542. The gear 563 is engaged with the rack 562.

[0058] Specifically, when the moving part 54 is started, the output end of the motor 542 drives the gear 563 to rotate, the gear 563 drives the rack 562 to move, and the rack 562 drives the blocking plate 561 to move. When the blocking plate 561 moves, the through hole is not connected to the air inlet 1 and the air outlet 2, and the blocking plate 561 closes the air inlet 1 and the air outlet 2.

[0059] By setting the sealing member 56, when the Freon inside the box body 4 leaks, the blocking plate 561 can seal the air inlet 1 and the air outlet 2, preventing the Freon from entering the external environment through the air inlet 1 and the air outlet 2.

[0060] like Figure 1-11 As shown, a second limiting plate 57 is fixedly connected to the front and rear sides of the box body 4, the mounting frame 511 can be fixedly connected to the second limiting plate 57, the bottom surface of the second limiting plate 57 is fixedly connected to a sealing gasket, and the top surface of the abutting frame 513 is fixedly connected to a sealing gasket.
