DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it. However, the illustrated embodiments are not intended to limit the present utility model.

[0023] Embodiment 1

[0024] Referring to Figure 1 As shown, the present utility model discloses a water vapor collection device for a high-temperature tank, including:

[0025] An air extraction part 1, the air extraction part 1 includes an air extraction cylinder 11, a suction pipe 12 is arranged at the bottom of the air extraction cylinder 11, and an air outlet pipe 13 is arranged at the top of the air extraction cylinder 11; the suction pipe 12 and the air outlet pipe 13 are respectively communicated with the inside of the air extraction cylinder 11;

[0026] A condensation part 2, the condensation part 2 includes a condensation pipe 21, the condensation pipe 21 is spirally arranged in the air extraction cylinder 11, the water inlet end 22 of the condensation pipe 21 penetrates through the bottom of the air extraction cylinder 11, and the water outlet end 23 of the condensation pipe 21 penetrates through the top of the air extraction cylinder 11; a drain port 111 is further arranged at the bottom of the air extraction cylinder 11.

[0027] It can be seen that the suction pipe 12 in the present utility model is used to collect the water vapor evaporated from the high-temperature tank. After the liquid medicine in the high-temperature tank evaporates to form steam, it enters from the suction port and then exits from the air outlet. It is cooled and liquefied in the air extraction cylinder 11 through the condensation part 2. The function of the entire condensation part 2 is to collect the steam generated by the high-temperature water tank during operation. Specifically, the condensation part 2 includes a condensation pipe 21, and ice water is introduced into the condensation pipe 21. The ice water is input from the bottom of the condensation pipe 21 and output from the top. After the liquid medicine steam is drawn in from the suction port, the liquid medicine steam will liquefy when it encounters the condensation pipe 21 and form liquid medicine again, which flows out from the drain port 111 at the bottom of the suction port. As a preferred solution of the present utility model, the structure of the condensation pipe 21 is a spiral structure. When the steam of the liquid medicine enters the air extraction cylinder 11, it increases the contact area between the steam of the liquid medicine and the condensation pipe 21, improving the liquefaction efficiency. Secondly, the ice water in the condensation pipe 21 adopts the method of low inlet and high outlet, which can ensure that the condensation pipe 21 is filled with ice water and improve the cooling rate.

[0028] The present utility model connects the suction pipe 12 with the high-temperature tank to collect the evaporated liquid medicine water vapor in the high-temperature tank, so that the liquid medicine in the water vapor state contacts the condensation pipe 21 in the air extraction cylinder 11. After the liquid medicine water vapor is cooled and liquefied, it is discharged from the drain port 111. The present utility model can collect the water vapor generated in the high-temperature tank, avoid the water vapor from overflowing and polluting other soaking liquids, and ensure the production quality of the product.

[0029] Further, the air extraction part 1 further includes a support cylinder 14, the support cylinder 14 is arranged inside the air extraction cylinder 11, and the condensation pipe 21 is arranged between the support cylinder 14 and the air extraction cylinder 11.

[0030] Specifically, the support cylinder 14 is arranged inside the air extraction cylinder 11, and the space formed between the air extraction cylinder 11 and the support cylinder 14 is used to install the spiral condensation pipe 21. On the one hand, it reduces the cross-sectional area of the water vapor passing through the air extraction pipe 12, and on the other hand, it increases the contact area and contact time between the water vapor and the condensation pipe 21. It avoids the situation that the water vapor is drawn away without liquefaction after entering the air extraction cylinder 11, and further improves the efficiency of water vapor liquefaction.

[0031] Further, support rods 15 are arranged between the two ends of the support cylinder 14 and the inner wall of the air extraction cylinder 11. Specifically, the support cylinder 14 is fixed inside the air extraction cylinder 11 through the support rods 15.

[0032] Further, the inner diameter size of the spiral of the condensation pipe 21 is equal to the outer diameter size of the support cylinder 14.

[0033] Specifically, in addition to increasing the passing time of the water vapor, the support cylinder 14 can also support the condensation pipe 21. The condensation pipe 21 is installed closely against the support cylinder 14 and is fixed on the outer wall of the support cylinder 14.

[0034] Further, a wind valve 16 is arranged at the port of the air outlet pipe 13.

[0035] Specifically, the wind valve 16 is arranged at the port of the air outlet pipe 13, which is used to adjust the size of the air outlet, change the air output volume, and further change the flow rate of the water vapor, so as to control the time for the water vapor to pass through the condensation pipe 21 and change the liquefaction rate.

[0036] Further, a connecting flange 17 is arranged at the port of the air extraction pipe 12 away from the air extraction cylinder 11.

[0037] Specifically, one end of the air extraction pipe 12 is connected to the high-temperature tank, and the detachable connection between the air extraction pipe 12 and the high-temperature tank is realized through the connecting flange 17.

[0038] Embodiment 2

[0039] Refer to Figure 2 As shown, a PCB board full-process device includes the high-temperature tank water vapor collection device described in Embodiment 1, and further includes a high-temperature tank body 3. An installation opening 31 is provided at the top of the high-temperature tank body 3, and the installation opening 31 is connected to the air extraction pipe 12.

[0040] Specifically, during the actual installation process, one end of the exhaust duct 12 is connected to the installation port 31 on the high-temperature tank body 3, and a sealing ring is provided between the connecting flange 17 and the installation port 31 to improve the sealing rate. The water vapor generated in the high-temperature tank will be sucked into the exhaust cylinder 11 from the installation port 31.

[0041] Furthermore, it also includes a vacuum generator 4, and the vacuum generator 4 is connected to the outlet duct 13.

[0042] Specifically, in the present utility model, the power for the exhaust cylinder 11 to achieve exhaust is provided by the vacuum generator 4. The vacuum generator 4 generates negative pressure to pump out the water vapor generated in the high-temperature tank.

[0043] Furthermore, the drain port 111 is communicated with the high-temperature tank body 3.

[0044] As a preferred solution of the present utility model, the liquid medicine water vapor is liquefied to form liquid medicine again, and after flowing out from the drain port 111, it is directly introduced into the high-temperature tank body 3 for recycling, reducing the waste of liquid medicine and lowering the production cost.

[0045] In summary, the present utility model introduces a high-temperature tank water vapor collection device and a PCB board full-process equipment. The present utility model connects the exhaust duct 12 with the high-temperature tank to collect the liquid medicine water vapor evaporated in the high-temperature tank, so that the liquid medicine in the water vapor state contacts the condensing pipe 21 in the exhaust cylinder 11, and the liquid medicine water vapor is liquefied by cooling and discharged from the drain port 111. The present utility model can collect the water vapor generated in the high-temperature tank, avoid the water vapor overflowing and polluting other soaking liquids, and ensure the production quality of the product.

[0046] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
