Problems solved by technology
[0004] When it is necessary to detect the concentration of the concentrated liquid in the boiler, it is necessary to turn the handle quickly. This fast turning action is inevitably inconvenient, which increases the detection process and takes time.

Embodiment Construction
[0026] In order to distinguish the front and back of the part, the surface close to the handle is called the front, and the surface away from the handle is called the back.
[0027] Such as figure 1 As shown, the side wall of the boiler unit is provided with a sampling unit 14 near the bottom, refer to figure 2 The sampling unit 14 includes a base body 1401 , a movable rod 1403 , a limit pin 1402 , a sampling chamber 1405 , a sampling hole 1404 , a first sleeve 1407 , a second sleeve 1410 , and an equal pressure chamber 1409 .
[0028] The base body 1401 is provided with a ventilation passage 1408, and the first and last ends of the ventilation passage 1408 communicate with the isobaric chamber 1409 and the outside atmosphere respectively. The air pressure is consistent, so that the movable rod 1403 can move more flexibly. The movable rod 1403 is provided with a handle 1406 near the front of the substrate 1401. The diameter of the handle 1406 is larger than the inner diamete...

The invention relates to the field of preparation of concentrated solutions and in particular relates to a design method of a sampling unit for equipment for preparing a concentrated solution under low pressure and at a low boiling point. The design method is characterized in that a renewable channel is formed in a movable rod, the head end of the renewable channel extends into the bottom of a sampling hole, and the tail end of the renewable channel extends to be away from a handle end and to the outer cylindrical surface of the movable rod; when the sampling hole is located in a sampling cavity, the tail end of the renewable channel is also located in the sampling cavity; when the sampling hole is located in a shaft sleeve and is close to the front surface of the shaft sleeve, the tail end of the renewable channel is located in the shaft sleeve and is close to the back surface of the shaft sleeve; when the sampling hole is located outside a base body, the tail end of the renewable channel is located in the shaft sleeve and is close to the front surface of the shaft sleeve. As the renewable channel is arranged, a concentrated solution in the sampling hole is renewed in real time, so that when a solution in a boiler is sampled, a handle does not need to be rotated rapidly, the movable rod is only required to be pulled out, and the operation is convenient and time-saving.
Description
technical field [0001] The invention relates to the field of concentrated liquid preparation, in particular but not exclusively to a design method of a sampling unit for preparing concentrated liquid. Background technique [0002] The boiling point of water decreases with the decrease of air pressure, so reducing the pressure can make water boil at a relatively low temperature, and the boiling water continuously converts liquid water into hot water vapor, and the hot water vapor will be at the interface between cold and hot Condensation into water mist, a large amount of water mist converges into water droplets, and a large amount of water droplets converges into water flow. [0003] For this reason, people have proposed a device that uses the above principle to remove the water in the mixed liquid, that is, the equipment for preparing the concentrated liquid, condensing the hot steam generated in the boiler into liquid water, and then transporting the water to a specific co...
