[0002] Defoaming agents can reduce the surface tension of water, solutions, suspensions, etc., prevent the formation of foam, or reduce or eliminate the original foam. Defoaming agents are widely used, such as in the food industry, papermaking industry, water treatment, oil production industry, printing and dyeing industry, coating industry, detergent industry, rubber latex industry, aerosol industry, daily chemical industry, pharmaceutical industry, dairy industry, etc. Reactors are needed in the production of environmentally friendly defoaming agents. In the prior art, the reactor is usually directly evacuated by a vacuum pump, and the waste liquid in the extracted gas-liquid mixture will contain harmful substances, and the harmful substances will mostly cause certain damage to the vacuum pump when passing through the vacuum pump, thereby affecting the service life of the vacuum pump. Utility Model Content

[0003] The utility model proposes that the reactor is usually directly evacuated by a vacuum pump, and the waste liquid in the extracted gas-liquid mixture may contain harmful substances, and the harmful substances may cause certain damage to the vacuum pump when passing through the vacuum pump, thereby affecting the service life of the vacuum pump.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a reactor body, a first guide pipe connected to the top of one side of the reactor body is fixedly connected to the first guide pipe, a drainage assembly connected to the bottom of the first guide pipe is fixedly connected to the drainage assembly, an inverted C-shaped guide pipe matched with the drainage assembly is fixedly connected to one side of the upper surface of the drainage assembly, and an air pump is installed at one end of the inverted C-shaped guide pipe.

[0005] Preferably, the inner wall of the first flow guide tube is fixedly connected with a liquid blocking plate. Through the setting of the liquid blocking plate, when the staff uses the equipment to evacuate the reactor, the defoaming agent carried by the airflow in the reactor drawn during the vacuuming process can be blocked by the liquid blocking plate, so that the defoaming agent drawn during the vacuuming process is retained in the first flow guide tube and slides back into the reactor body through the inclined first flow guide tube. A solenoid valve is installed on the surface of the first flow guide tube near the liquid blocking plate. Through the setting of the solenoid valve, when the staff finishes drawing the airflow in the reactor body, the staff can close the solenoid valve, thereby preventing the inside of the reactor body from re-inhaling air from the first flow guide tube due to the negative pressure generated after the vacuuming.

[0006] Preferably, the drainage assembly includes a shell fixedly connected to the bottom end of the first flow guide tube, and a collecting piece is fixedly connected to the inner top wall of the shell near the first flow guide tube. Through the setting of the collecting piece, during the vacuuming process, the drawn airflow and part of the defoaming agent carried out are collected and fall onto the surface of the inner arc surface, and fall into the inner bottom wall of the shell through the leakage port.

[0007] Preferably, a liquid leakage plate is fixedly connected to the middle of the inner wall of the shell, an inner arc surface is provided in the middle of the upper surface of the liquid leakage plate, and a liquid leakage port is provided in the middle of the lower surface of the inner arc surface.

[0008] Preferably, a spoiler is fixedly connected to the inner wall of the shell near the leakage plate, a drain pipe communicating therewith is fixedly connected to the bottom of the shell surface, and a control valve is installed on the upper surface of the drain pipe.

[0009] Preferably, two symmetrically distributed L-shaped flow guide tubes are fixedly connected to the front of the reactor body, the two L-shaped flow guide tubes are both connected to the reactor body, and pressure gauges are fixedly connected to opposite sides of the two L-shaped flow guide tubes.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The vacuum extraction equipment for the defoaming agent reactor is provided with structures such as the first guide tube and the drainage component. When the staff uses the vacuum pump to perform a vacuum operation on the inside of the reactor body, during the pumping process, the gas and the gas-liquid mixture in the reactor body can flow into the shell from the first guide tube, and when the gas and the gas-liquid mixture pass through the liquid blocking plate, part of the liquid is blocked by the liquid blocking plate, thereby reducing the loss of liquid, and when the airflow passes through the collecting piece, part of the liquid can be gathered and condensed together, and then the condensed liquid can drip onto the surface of the inner arc surface, and then the liquid on the inner arc surface can leak into the inner bottom wall of the shell from the liquid leakage port, and then the airflow can flow from the inverted C-shaped guide tube through the spoiler to the vacuum pump, and then be discharged from the vacuum pump, thereby solving the problem that when the traditional method of directly using the vacuum pump to pump the gas in the reactor body, the passively extracted liquid passes through the vacuum pump to damage the vacuum pump and reduce the service life of the vacuum pump.

[0018] Example 1

[0019] See also Figures 1 to 4 As shown, the utility model provides a technical solution: a vacuum extraction device for a defoaming agent reactor, comprising a reactor body 1, a first guide pipe 2 connected to the reactor body 1 is fixedly connected to the top of one side of the reactor body 1, a drainage component 3 connected to the first guide pipe 2 is fixedly connected to the bottom end of the first guide pipe 2, an inverted C-shaped guide pipe 4 matched with the drainage component 3 is fixedly connected to one side of the upper surface of the drainage component 3, and an air pump 5 is installed at one end of the inverted C-shaped guide pipe 4.

[0020] In this embodiment: when the staff uses the defoaming agent vacuum extraction equipment to extract the air in the reactor body 1, the airflow first passes through the first guide pipe 2, and then enters the drainage component 3, so that the passively extracted liquid falls into the drainage component 3, thereby preventing the passively extracted liquid from damaging the vacuum pump 5.

Through the arrangement of the collecting piece 302, during the vacuuming process, the drawn airflow and part of the defoaming agent carried out are collected and fall on the surface of the inner arc surface 304, and fall into the inner bottom wall of the shell 301 through the leakage port 305. A leakage plate 303 is fixedly connected to the middle of the inner wall of the shell 301, and an inner arc surface is opened in the middle of the upper surface of the leakage plate 303. 304, a leakage port 305 is provided in the middle of the lower surface of the inner arc surface 304, two symmetrically distributed L-shaped flow guide pipes 6 are fixedly connected to the front of the reactor body 1, the two L-shaped flow guide pipes 6 are connected to the reactor body 1, and the opposite sides of the two L-shaped flow guide pipes 6 are commonly fixedly connected with a pressure gauge 7, the inner wall of the shell 301 is fixedly connected with a spoiler 306 near the leakage plate 303, the bottom of the shell 301 surface is fixedly connected with a drain pipe 307 connected thereto, and a control valve 308 is installed on the upper surface of the drain pipe 307.

[0023] In the present embodiment: the inner wall of the first flow guide tube 2 is fixedly connected with a liquid blocking plate 201. Through the setting of the liquid blocking plate 201, when the staff uses the device to evacuate the reactor, the defoaming agent carried by the airflow in the reactor drawn during the vacuuming process can be blocked by the liquid blocking plate 201, so that the defoaming agent drawn during the vacuuming process is retained in the first flow guide tube 2 and slides back into the reactor body 1 through the inclined first flow guide tube 2. A solenoid valve 202 is installed on the surface of the first flow guide tube 2 near the liquid blocking plate 201. Through the setting of the solenoid valve 202, when the staff finishes drawing the airflow in the reactor body 1, the staff can close the solenoid valve 202, thereby preventing the reactor body 1 from re-inhaling air from the first flow guide tube 2 due to the negative pressure generated after the vacuuming.

[0024] In this embodiment, the gas in the reactor body 1 first passes through the first flow conduit 2 through the pumping of the vacuum pump 5, and when the gas and the passively pumped liquid pass through the first flow conduit 2, the liquid can pass through the barrier of the liquid blocking plate 201, thereby reducing the amount of liquid entering the first flow conduit 2, and then the gas after the initial barrier of the barrier plate passes through the collecting piece 302, and the collecting piece 302 collects the gas, and the liquid that partially overflows the liquid blocking plate 201 can be collected at the collecting piece 302 and then drip onto the surface of the inner arc surface 304, and then slide from the surface of the inner arc surface 304 to the liquid leakage port 305, and then fall from the liquid leakage port 305 to the inner bottom wall of the shell 301, and then the airflow can flow from the inverted C-shaped flow conduit 4 to the vacuum pump 5 after being disturbed by the spoiler 306, and then be discharged from the output end of the vacuum pump 5.
