[0002] The working principle of the water vapor capture pump is to place a low-temperature refrigeration coil in the vacuum chamber or at the pump port of the oil diffusion pump.

[0031] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Combination Figures 1 to 11As shown, the water vapor capture pump of this embodiment includes a refrigerator part and a coil part, the refrigerator part includes a refrigerator 1 and a low-temperature connection outlet pipe 2 and a low-temperature connection return pipe 3 connected to the refrigerator 1, and the coil part includes a first coil 5 located in the first pipeline 4 and a second coil 7 located in the second pipeline 6, the first coil 5 can be connected with the low-temperature connection outlet pipe 2 and the low-temperature connection return pipe 3, and the second coil 7 can also be connected with the low-temperature connection outlet pipe 2 and the low-temperature connection return pipe 3. The first pipeline 4 and the second pipeline 6 can be opened alternately. When the first pipeline 4 is opened, the first coil 5 is connected with the low-temperature connection outlet pipe 2 and the low-temperature connection return pipe 3, and the second coil 7 is disconnected from the low-temperature connection outlet pipe 2 and the low-temperature connection return pipe 3, so that the first coil 5 performs water vapor capture in the first pipeline 4. When the second pipeline 6 is opened, the first coil 5 is disconnected from the low-temperature connection outlet pipe 2 and the low-temperature connection return pipe 3, and the second coil 7 is connected with the low-temperature connection outlet pipe 2 and the low-temperature connection return pipe 3, so that the second coil 7 performs water vapor capture in the second pipeline 6.

[0033] In this embodiment, by respectively arranging a first coil in the first pipe and a second coil in the second pipe, the first coil and the second coil can be respectively connected to the refrigeration machine to form alternating operation, that is, when one coil is performing water vapor capture operation, the other coil can perform ice crystal removal operation, so that the entire water vapor capture pump always maintains a high condensation efficiency, thereby improving the working efficiency of the water vapor capture pump.

[0034] Combination Figure 2 As shown, in the water vapor capture pump of this embodiment, the first pipeline 4 is composed of a pipeline seat 8 and a first pipeline shell 9, the first pipeline shell 9 is connected to the pipeline seat 8, and the first pipeline shell 9 is provided with an inlet 10 of the first pipeline, the pipeline seat 8 is provided with an outlet 11 of the first pipeline, and the first coil 5 extends to the inlet 10 of the first pipeline and the outlet 11 of the first pipeline, thereby forming condensation of water vapor passing through the first pipeline 4. The second pipeline 6 is composed of a pipeline seat 8 and a second pipeline shell 12, the second pipeline shell 12 is connected to the pipeline seat 8, and the second pipeline shell 12 is provided with an inlet 13 of the second pipeline, the pipeline seat 8 is provided with an outlet 14 of the second pipeline, and the second coil 7 extends to the inlet 13 of the second pipeline and the outlet 14 of the second pipeline, thereby forming condensation of water vapor passing through the second pipeline 6. By respectively arranging and connecting the first pipeline shell 9 and the second pipeline shell 12 to the pipeline seat 8, the first pipeline 4 and the second pipeline 6 that are independent of each other are formed, thereby realizing the alternating water vapor capture work of the two coils.

[0035] In addition, in the water vapor capture pump of this embodiment, the first coil 5 and the second coil 7 are both rotatably arranged, that is, the first coil 5 is rotatably arranged in the first pipeline 4, and the second coil 7 is rotatably arranged in the second pipeline 6. By rotatably arranging the first coil and the second coil, the water vapor passing through the corresponding pipeline can be uniformly captured and condensed, so that the thickness of the ice crystals condensed on the coils is uniform, thereby improving the condensation effect.

[0036] Furthermore, in the water vapor capture pump of this embodiment, the first coil 5 and the second coil 7 can also rotate at high speed and low speed respectively. In this way, when the first coil or the second coil performs water vapor capture, the coil can be controlled to rotate at low speed, so that the coil can be in uniform and sufficient contact with the passing water vapor, thereby improving the condensation effect of the water vapor; conversely, when the first coil or the second coil performs ice crystal removal operation, the coil can be controlled to rotate at high speed, using centrifugal force to quickly separate the condensed ice crystals, thereby improving the efficiency of ice crystal removal.

[0037] Combination Figure 2 As shown, in the water vapor capture pump of this embodiment, the coil part is further provided with a first heating wire 15 and a second heating wire 16.

[0038] At this time, by setting the first heating wire and the second heating wire, the coil in the de-icing state can be heated, so that the ice crystals on the coil can quickly melt into water, thereby increasing the speed of de-icing. In addition, in conjunction with the high-speed rotation of the coil, the centrifugal force generated by the rotation of the coil can be used to further accelerate the speed at which water leaves the coil, thereby further improving the efficiency of de-icing.

[0039] Combination Figure 2 and Fig.11 As shown, in the water vapor capture pump of the present embodiment, the coil part is further provided with a motor 17, a transmission disc 18, a first special-shaped shaft 19 and a second special-shaped shaft 20. Among them, the motor 17 is swingably arranged, and the transmission disc 18 is arranged on the output shaft of the motor 17. The first special-shaped shaft 19 is transmission-connected with the first coil 5 to drive the first coil 5 to rotate. The second special-shaped shaft 20 is transmission-connected with the second coil 7 to drive the second coil 7 to rotate. The first special-shaped shaft 19 and the second special-shaped shaft 20 both have a large diameter end and a small diameter end with a smooth transition, and the motor 17 can swing until the transmission disc 18 forms a transmission abutment with the large diameter end of the first special-shaped shaft 19 and forms a transmission abutment with the small diameter end of the second special-shaped shaft 20, that is, Fig.11In the position state shown, similarly, the motor 17 can also swing until the transmission plate 18 forms a transmission abutment with the small diameter end of the first special-shaped shaft 19 and forms a transmission abutment with the large diameter end of the second special-shaped shaft 20.

[0040] At this time, by setting a reciprocating motor-driven transmission disk to control the two special-shaped shafts to rotate at different speeds, one coil can be controlled to rotate at high speed and the other coil can be controlled to rotate at low speed, thereby meeting the rotation requirements of the two coils in different working states.

[0041] Among them, combined Figure 2 , Figure 6 and Fig.11 As shown, in the water vapor capture pump of this embodiment, the first special-shaped shaft 19 and the first coil 5 are connected by a transmission mechanism consisting of a first pulley 21, a second pulley 22 and a first belt 23. Specifically, the first pulley 21 is sleeved on the first special-shaped shaft 19, and the second pulley 22 is sleeved on the first coil shaft 46 that is rotatably connected to the first coil 5 and the pipe seat 8.

[0043] At this time, by controlling the push rod to extend or retract, the first swing rod can be rotated through the cooperation between the push rod pin and the first swing groove, thereby driving the swing block to swing back and forth, and then driving the motor to swing back and forth, changing the transmission connection position between the transmission disk and the first special-shaped shaft and the second special-shaped shaft.

[0044] Combination Figures 2 to 11As shown, in the water vapor capture pump of this embodiment, the coil part is also provided with a first vacuum plate 32, a second vacuum plate 33, a third vacuum plate 34 and a fourth vacuum plate 35 which are linked.

[0045] At this time, by respectively setting a vacuum plate at the inlet of the first pipe, the outlet of the first pipe, the inlet of the second pipe and the outlet of the second pipe, and setting the four vacuum plates in linkage, the second pipe can be in a disconnected state when the first pipe is connected, and the second pipe can be connected when the first pipe is in a disconnected state, thereby realizing the alternating operation of the two pipes for capturing water vapor.

[0046] Combination Figures 2 to 11 As shown, in the water vapor capture pump of this embodiment, the coil part is further provided with a first connecting rod 36, a second connecting rod 37, a second swinging rod 38 and a control rod 39.

At this time, by providing the extraction port, the water thrown off the high-speed rotating coil can be timely extracted and drained by using the external extraction system, so as to realize automatic cleaning and drying of the coil and ensure the subsequent working effect of the coil.

[0049] In addition, combined Figure 2 As shown, in the water vapor capture pump of this embodiment, the coil part is further provided with a first solenoid valve 44 and a second solenoid valve 45. The first solenoid valve 44 is located between the first coil 5 and the refrigerator 1, and is used to control the connection and disconnection between the first coil 5 and the low-temperature connection outlet pipe 2 and the low-temperature connection return pipe 3. The second solenoid valve 45 is located between the second coil 7 and the refrigerator 1, and is used to control the connection and disconnection between the second coil 7 and the low-temperature connection outlet pipe 2 and the low-temperature connection return pipe 3.

[0050] Combination Figures 1 to 11 As shown, when the water vapor capture pump of this embodiment is used to capture water vapor, the specific operation process is as follows:

[0052] When it is necessary to capture water vapor, the refrigerator 1 is turned on, the first solenoid valve 44 is controlled to be opened, and the second solenoid valve 45 is controlled to be closed, so that the refrigerant output by the refrigerator 1 passes through the first solenoid valve 44 and enters the first coil 5, so that the first coil 5 generates a low temperature, and the second heating wire 16 is turned on to heat the second coil 7. Figure 2 As shown, the first vacuum plate 32 is located at the inlet 10 of the first pipeline in an open position, the second vacuum plate 33 is located at the outlet 11 of the first pipeline in an open position, the third vacuum plate 34 is located at the inlet 13 of the second pipeline in a closed position, and the fourth vacuum plate 35 is located at the outlet 14 of the second pipeline in a closed position, so that the gas enters the first pipeline 4 from the inlet 10 of the first pipeline and flows out from the outlet 11 of the first pipeline. Under the low temperature of the first coil 5, the water vapor is condensed and solidified on the first coil 5. At the same time, the motor 17 is started to drive the transmission disc 18 to rotate. At this time, the transmission disc 18 is in Fig.11The position state shown, that is, the transmission disc 18 is in transmission abutment with the large diameter end of the first special-shaped shaft 19 and in transmission abutment with the small diameter end of the second special-shaped shaft 20, thereby driving the first special-shaped shaft 19 to rotate at a low speed and the second special-shaped shaft 20 to rotate at a high speed, and then driving the first coil 5 to rotate at a low speed in the first pipeline 4 through the first pulley 21, the second pulley 22 and the first belt 23 respectively, and driving the second coil 7 to rotate at a high speed in the second pipeline 6 through the third pulley 24, the fourth pulley 25 and the second belt 26, thereby making the first coil 5 evenly contact with the water vapor in the first pipeline 4, so that the thickness of the ice crystals condensed on the first coil 5 is uniform. At the same time, the second heating wire 16 heats the second coil 7, causing the ice crystals on the second coil 7 to melt and become liquid, and under the centrifugal force of the high-speed rotation of the second coil 7, the water on the second coil 7 is thrown off and collected in the second pipe 6, and the second extraction port 43 on the second pipe 6 is opened, and the water collected in the second pipe 6 is extracted by the external pump extraction system, so that the second coil 7 is automatically cleaned and dried.

The push rod 28 is controlled to contract, and the first swing rod 29 is moved through the push rod pin 31 and the first swing groove 30. Fig.10 As shown, the first swing rod 29 drives the swing block 27 to swing, and then the motor 17 swings, and the transmission plate 18 swings to the small diameter end of the first special-shaped shaft 19 and the large diameter end of the second special-shaped shaft 20, so as to drive the first special-shaped shaft 19 to rotate at a high speed and the second special-shaped shaft 20 to rotate at a low speed, and then the first coil 5 is driven to rotate at a high speed in the first pipeline 4 through the first pulley 21, the second pulley 22 and the first belt 23, and the second coil 7 is driven to rotate at a low speed in the second pipeline 6 through the third pulley 24, the fourth pulley 25 and the second belt 26. At the same time, the swing block 27 swings synchronously with the second swing rod 38, that is, it drives the second swing rod 38 to rotate. Fig. 9 The control rod 39 is rotated clockwise as shown, thereby causing the control pin 41 and the second swing slot 40 to move to the left. Fig. 9As shown, the second vacuum plate 33 and the fourth vacuum plate 35 are moved downward by the control rod 39, and the first vacuum plate 32 and the third vacuum plate 34 are moved downward by the first connecting rod 36 and the second connecting rod 37 respectively, thereby switching the inlet 10 of the first pipe and the outlet 11 of the first pipe to a blocked state, and switching the inlet 13 of the second pipe and the outlet 14 of the second pipe to an open state, so that the gas enters the second pipe 6 from the inlet 13 of the second pipe and then flows out from the outlet 14 of the second pipe, and under the low temperature of the second coil 7, the water vapor is condensed and solidified on the second coil 7, and under the low speed rotation of the second coil 7, the thickness of the ice crystals condensed on the second coil 7 is made uniform. At the same time, the first heating wire 15 heats the first coil 5, causing the ice crystals on the first coil 5 to melt and become liquid, and under the centrifugal force of the high-speed rotation of the first coil 5, the water on the first coil 5 is thrown off and collected in the first pipe 4, the first extraction port 42 on the first pipe 4 is opened, and the water collected in the first pipe 4 is extracted by an external pump extraction system, so that the first coil 5 is automatically cleaned and dried.
