Detailed Description
The utility model relates to a liquid sac flow field stabilizing device, which consists of a temperature sensor 1, a liquid sac 2, a temperature measuring tube 3, a connecting tube 4 and a liquid baffle plate 5. The liquid baffle plate 5 divides the liquid bag 2 into two spaces, one side close to the front-end equipment is a liquid storage area, and the side close to the subsequent equipment is a flowing area. The liquid from the front-end equipment is blocked by the liquid baffle plate 5 and gathers in the liquid storage area, when the liquid level of the gathered liquid is higher than the top surface of the liquid baffle plate 5, the liquid normally flows to the subsequent equipment, the bottom of the liquid baffle plate 5 is provided with a balance hole, the liquid gathering in the liquid storage area is always in a flowing updating state, and the temperature of the liquid gathering is consistent with the temperature of the main fluid. The temperature measuring tube 3 is a one-way sleeve with one end open and the other end closed, and the closed end of the temperature measuring tube is immersed below the liquid level of the liquid storage area. The temperature sensor 1 is arranged at the open end of the temperature measuring tube, the measuring end of the temperature sensor extends into the closed end of the temperature measuring tube 3, and the temperature of the liquid outside the closed end of the temperature measuring tube 3 can be measured in real time. A connecting tube 4 is mounted in the flow area for transporting the liquid to subsequent equipment.
The following is specifically described in conjunction with the above drawings:
with reference to fig. 1, the liquid baffle 5 divides the liquid bag 2 into two spaces, namely a liquid storage area and a flow area, liquid from front-end equipment is collected in the liquid storage area, and when the liquid level of the collected liquid is higher than the top surface of the liquid baffle 5, the main fluid flows to the flow area and normally flows to subsequent equipment. The liquid in the liquid storage area is always in a renewal state through the balance holes at the bottom of the liquid baffle plate 5, and the temperature of the liquid storage area is ensured to be consistent with that of the main fluid. The closed end of the temperature measuring tube 3 is immersed in the liquid storage area liquid, the measuring end of the temperature sensor 1 arranged in the temperature measuring tube 3 is tightly attached to the closed end of the temperature measuring tube 3, and the temperature of the liquid outside the closed end of the temperature measuring tube 3 can be measured in real time. And a connecting pipe 4 arranged in the flow area and used for conveying the liquid to subsequent equipment.
Referring to fig. 2, in the conventional sac apparatus, after entering into the sac 2, the liquid from the front end device directly enters into the connecting tube 4 and is transported to the subsequent device. Because the liquid flow from the front end is unstable, it is difficult to form a stable liquid level in the liquid bag, and the closed end of the temperature measuring tube 3 cannot be immersed in the liquid continuously, so that the temperature sensor 1 installed in the temperature measuring tube 3 cannot measure the liquid temperature in a low liquid level state, and an error temperature signal is fed back.
In the application example shown in fig. 3, the flow field stabilizing device using the annular liquid baffle plate is shown, when the connecting pipe 4 is connected with the pump 6, the annular liquid baffle plate 51 is used, and the annular liquid baffle plate 51 also divides the liquid bag 2 into a liquid storage area and a flow area. Because the connecting pipe 5 is connected with the suction inlet of the pump 6, the liquid in the liquid bag has strong flowing power, and a larger liquid storage space is needed for stabilizing the flow field of the liquid in the liquid bag 2, the annular liquid baffle plate 51 directly coincides the flowing area with the inlet of the connecting pipe 4, the liquid storage space is enlarged, the fluctuation of the liquid in the liquid storage space is reduced to the maximum extent, the closed end of the temperature measuring pipe 3 can be continuously immersed in the liquid, and the temperature sensor 1 can continuously measure the temperature of the liquid.
According to the liquid bag stabilizing device, the liquid baffle plate is additionally arranged, and the liquid storage area with a certain liquid level is formed in the original liquid bag, so that the temperature of liquid in the liquid bag can be continuously measured by temperature measuring equipment, the authenticity of a measuring result is ensured, and a foundation is laid for the accurate control of a unit.
The above description is only an example of the present invention and is not intended to limit the scope of the present invention, and all equivalent structures made by using the contents of the specification and the drawings, or used directly or indirectly in the related technical fields, are included in the scope of the present invention.
