Description

Technical Field

[0001] This application relates to the field of hybrid technology, and more specifically to a pre-emulsification tank. Background Technology

[0002] When using a preemulsification tank, operators usually need to open the observation window to observe the material inside. However, the preemulsification process typically generates a large amount of water vapor or organic gases. When the observation window is opened, these gases and water vapor will leak out. If operators observe the material through the window at this time, they will inhale the organic gases, which is harmful to their health. Summary of the Invention

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a pre-emulsification container that can prevent the inhalation of harmful gases when a person uses the observation window. The technical solution adopted includes:

[0004] A pre-emulsification tank includes a tank body with an opening communicating with its interior. An openable and closable observation window is installed on the opening. An air extraction pipe communicating with the opening is installed on the tank body and is used to extract air from the opening when the observation window is opened.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: a buffer tube is installed on the tank body, the diameter of the buffer tube is larger than the diameter of the opening, and the air extraction pipe is connected to the inside of the buffer tube.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the air extraction pipe is further provided with a valve, the valve is used to open the air extraction pipe after the observation window is opened, and to cut off the air extraction pipe after the observation window is closed.

[0020] Reference Figure 1-2 This application proposes an embodiment of the pre-emulsification tank, which includes a tank body 10. The tank body 10 has an opening 20 communicating with its interior. An openable and closable observation window 30 is installed on the opening 20. An exhaust pipe 40 communicating with the opening 20 is installed on the tank body 10. The exhaust pipe 40 is used to exhaust air from the opening 20 after the observation window 30 is opened.

[0021] This application uses the extraction pipe 40 to actively extract the organic gas flowing to the opening 20, thereby avoiding direct contact between the person at the observation window 30 and the harmful gas and reducing the probability of the operator being exposed to high concentrations of organic gas. Furthermore, by directly installing the extraction pipe 40 on the tank body 10, the cost is low and the reliability is higher.

[0022] Preferably, a buffer tube 50 is installed on the tank body 10, the diameter of the buffer tube 50 is larger than the diameter of the opening 20, and the suction pipe 40 is in communication with the interior of the buffer tube 50.

[0023] Organic gas flows into the buffer tube 50 from the opening 20. Since the cross-sectional area of ​​the buffer tube 50 is larger than that of the opening 20, the gas flow rate into the buffer tube 50 is reduced, which prolongs the residence time of the organic gas in the buffer tube 50, ensuring the suction effect of the organic gas. Moreover, the reduced flow rate of the organic gas can reduce the suction power, which is beneficial to saving energy.

[0024] Furthermore, one end of the buffer tube 50 is connected to the opening 20, the observation window 30 is opened at the other end of the buffer tube 50, and the diameter of the buffer tube 50 gradually increases from the opening 20 toward the observation window 30.

[0025] The buffer tube 50 adopts a gradually expanding design, and the airflow velocity of the buffer tube 50 gradually decreases, further extending the residence time of organic gas in the buffer tube 50.

[0026] Since a large amount of harmful organic gases are generated during the pre-emulsification process, an exhaust gas treatment device 70 is also included. The end of the exhaust pipe 40 away from the tank 10 is connected to the exhaust gas treatment device 70. The exhaust pipe 40 is used to guide the harmful gases to the exhaust gas treatment device 70. The organic gases flowing out of the tank 10 from the opening 20 are discharged through the exhaust pipe 40 and then sent to the exhaust gas treatment device 70 for treatment, so as to prevent the organic gases from flowing directly into the atmosphere and harming the environment.

[0027] Preferably, the extraction pipe 40 is also equipped with a valve 60. The valve 60 is used to open the extraction pipe 40 after the observation window 30 is opened, and to close the extraction pipe 40 after the observation window 30 is closed. Since the extraction pipe 40 connects the opening 20 and the outside, in order to ensure that the reaction environment of the tank 10 is sealed and stable during the pre-emulsification process, the valve 60 closes the extraction pipe 40 to keep the tank 10 in a sealed state. When it is necessary to observe the material inside the tank 10 through the observation window 30, the valve 60 opens the extraction pipe 40 to generate negative pressure inside the extraction pipe 40 and allow harmful gases to be discharged from its interior.

[0028] Specifically, the suction pipe 40 includes a pipe body 41 and a suction pump 42. The pipe body 41 is installed on the tank 10 and communicates with the opening 20. The suction pump 42 is communicated with the inside of the pipe body 41. The tank 10 is also provided with a detection device 80, which is used to detect whether the observation window 30 is open, so that the suction pump 42 is started after the observation window 30 is opened.

[0029] Since the observation window 30 is normally closed, and the inside of the tank 10 is observed intermittently through the opening 20, the vacuum pump 42 in this application needs to be started intermittently to avoid unnecessary energy consumption caused by maintaining a negative pressure state in the vacuum pipe 40. Therefore, this application also provides a detection device 80 on the tank 10 to detect whether the observation window 30 is open, so that the vacuum pump 42 only starts when the observation window 30 is open, and does not work when the observation window 30 is closed.

[0030] Specifically, the observation window 30 is hinged to the tank 10 on one side, and connected to the tank 10 on the opposite side via a detachable connection mechanism. The detection device 80 includes a proximity sensor disposed at the opening 20 of the tank 10 and located on the opposite side of the observation window 30.

[0031] The valve 60 is an electrically controlled valve, and the negative pressure generating device is a vacuum pump 42. The proximity sensor is connected to the controller along with the electrically controlled valve 60 and the vacuum pump 42. When the proximity sensor detects that the observation window 30 is open, it sends a signal to the vacuum pump 42 and the electrically controlled valve 60. The electrically controlled valve 60 opens the vacuum pipe 40, and the vacuum pump 42 starts and generates negative pressure in the vacuum pipe 40. When the proximity sensor detects that the observation window 30 is closed, it sends a signal to the vacuum pump 42 and the electrically controlled valve 60. The electrically controlled valve 60 cuts off the vacuum pipe 40, and the vacuum pump 42 stops.

[0032] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
