Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Example 1

As shown in fig. 1-2, a resin reaction tank with a sampling device comprises a reaction tank body 1, a sampling tube 2 and a sampling tank 3; the bottom wall of the reaction tank body 1 is connected with the sampling tube 2; the sampling tube 2 is provided with an upper valve 21 and a lower valve 22; the outlet end of the sampling tube 2 is opposite to the inlet of the sampling tank 3; the sampling tank 3 is connected with the reaction tank body 1 through a negative pressure pump 4; the pipeline between the upper valve 21 and the lower valve 22 is connected with the negative pressure pump 4 through a branch pipe 5; the branch pipe 5 is provided with a branch valve 51.

In the specific implementation process, when sampling is needed, the upper valve 21 and the lower valve 22 are opened, a sample is connected into a sampling container, and the valves are closed after sampling is finished. At this time, there is a residual sample in the sampling tube 2, and the residual sample can be discharged into the sampling tank 3 by opening the valve. The negative pressure pump 4 can pump the residual sample in the sampling tank 3 back to the reaction tank body 1 on one hand, so that waste is avoided; on the other hand, because the sample has certain viscosity, the sample in the sampling tube 2 is difficult to discharge cleanly under the action of no external suction force, and the negative pressure pump 4 can suck the residual sample in the sampling tube 2 by the negative pressure force through the branch tube 5, so that the sampling tube 2 is prevented from being blocked after the sample is solidified.

In this embodiment, a liquid level meter is arranged in the sampling tank 3.

In the specific implementation process, a liquid level threshold value can be set, and when the sample in the sampling tank 3 reaches a certain height, the negative pressure pump 4 is started to pump the sample back to the reaction tank body 1.

In this embodiment, an interlayer is disposed on the tube wall of the sampling tube 2; a heating plate is arranged in the interlayer.

In the concrete implementation process, the sample is easy to solidify and block the sampling tube 2 after being cooled, so that a heating plate is arranged to prevent the sample from solidifying. If the inner wall of the sample tube is solidified, the sample can be melted by the heating plate and then discharged.

In this embodiment, the outlet end of the sampling tube 2 is connected with a blowout preventer 6; the blowout preventer 6 is provided with a plurality of energy reducing holes 61 along the flow direction; the energy reducing hole 61 is spiral.

In the specific implementation process, the pressure in the reaction tank body 1 and the external pressure have a certain difference, the valve is opened during sampling, the sample can be sprayed out of the sampling tube 2 due to the internal and external pressure difference and the overhigh flow speed, and the sample is generally high in temperature and is easy to scald a sampling worker. The blowout preventer 6 is provided with a plurality of spiral energy-reducing holes 61, which increase disturbance in the sample flowing process, reduce liquid energy and reduce flow velocity.

In this embodiment, a temperature sensor is disposed on the inner wall of the sampling tank 3; and a heating pipe is arranged on the side wall of the sampling tank 3.

In the concrete implementation process, the residual samples in the sampling tube 2 are all discharged into the sampling tank 3, and after enough samples are collected into the reaction tank body 1, the samples are cooled and easily solidified in the storage process and are not easily collected, so that the temperature sensor and the heating tube are arranged to prevent the samples from solidifying.

In this embodiment, an automatic door is provided on the top wall of the sampling tank 3.

In the specific implementation process, if the sampling tank 3 is not a closed space, the sampling tank is not easy to extract cleanly when the sampling tank is withdrawn by negative pressure, and meanwhile, the smell of the sample can volatilize, so that the working environment is polluted.

In this embodiment, the blowout preventer 6 is screwed with the sampling tube 2.

In the specific implementation process, if the blowout preventer 6 is blocked, the blowout preventer can be replaced.

The foregoing is merely a preferred embodiment of the present utility model, and is not intended to limit the present utility model,

various modifications and variations of the present utility model will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model 0 should be included in the protection scope of the present utility model.
