[0032] The channel composed of the outlet pipe 201, the stop valve 203, the connecting pipe 204, the electric three-way valve 205, the first Y-type filter 206, the electromagnetic valve 207 and the rotor flowmeter 208 realizes the feeding operation of the liquid material to the reaction kettle, and the metering pump 202 and the electromagnetic valve 207 are used to realize the control of the dropping speed and the dropping amount of the liquid material.

[0033] The control ends of the metering pump 202, the electric three-way valve 205 and the electromagnetic valve 207 are electrically connected with the external controller through cables, and the signal output end of the rotor flowmeter 208 is electrically connected with the external controller through a cable.

[0034] In the embodiment, when the liquid material dropping operation needs to be performed for the reaction kettle, the operation steps are as follows:

[0035] 1. The dropping amount and the dropping speed of the liquid material to be dropped are input on the display screen of the control system;

[0036] 2. The start button is pressed, the external controller controls the metering pump 202 to work and the electromagnetic valve 207 to open, the metering pump 202 can run according to the set dropping speed, that is, the liquid material in the material dissolving tank 1 can be pumped out, and the liquid material flows through the outlet pipe 201, the stop valve 203 (it is to be noted that the stop valve 203 is in a normally open state), the electric three-way valve 205, the first Y-type filter 206, the electromagnetic valve 207, the rotor flowmeter 208 and the dropping pipe 209 in sequence, and finally enters the reaction kettle, in this process, the rotor flowmeter 208 synchronously monitors the flow rate and transmits the data to the display screen of the control system, so that the instantaneous and cumulative flow rates can be displayed, and at the same time, the running speed of the metering pump 202 can be adjusted according to the need, so as to adjust the required dropping speed;

[0037] 3. When the delivery amount reaches the set amount, the metering pump 202 stops working, and the electromagnetic valve 207 is closed.

[0038] Through the cooperation of the above multiple parts, the automatic dropwise addition operation of the liquid material is realized, and the fixed impurities possibly existing in the liquid material can be filtered through the first Y-type filter 206, so as to ensure the stable operation of the rotor flowmeter 208 and ensure the measurement accuracy of the rotor flowmeter 208.

[0039] Please refer to Figure 1 The impurity removal unit includes reflux pipes 210 and a second Y-type filter 211. The two reflux pipes 210 are respectively connected to the two ends of the second Y-type filter 211, and the other ends of the two reflux pipes 210 are respectively connected to an output end of the electric three-way valve 205 and the top of the material dissolving tank 1.

[0040] The channel composed of the discharge pipe 201, the stop valve 203, the connecting pipe 204, the electric three-way valve 205, the reflux pipe 210, and the second Y-type filter 211 is used to realize the circulating flow of the liquid material in the material dissolving tank 1, and the second Y-type filter 211 is used to filter and remove the impurities in the circulating liquid material.

[0041] In this embodiment, it needs to be explained that the material dissolving tank 1 is provided with a feeding port for feeding powder material and water, and a stirring mechanism for stirring the mixture of the material and water. This structure is a conventional structure of the dissolving tank in the prior art, and therefore, it will not be described here.

[0042] After the material in the material dissolving tank 1 is dissolved, the electric three-way valve 205 can be controlled by an external controller to switch, so that the pipeline between the first Y-type filter 206 and the stop valve 203 is disconnected, and the pipeline between the second filter 211 and the stop valve 203 is connected. Then, the metering pump 202 is started to operate. At this time, the liquid material in the material dissolving tank 1 will flow along the pipeline composed of the discharge pipe 201, the stop valve 203, the connecting pipe 204, the electric three-way valve 205, the reflux pipe 210, and the second Y-type filter 211, that is, the liquid material in the material dissolving tank 1 presents a circulating flow. In this process, the second Y-type filter 211 can filter and intercept the solid impurities in the liquid material. After circulating the liquid material in the material dissolving tank 1 for a period of time, the solid impurities in the liquid material can be efficiently filtered.

[0043] Then, the electric three-way valve 205 can be controlled to switch again, so that the pipeline between the first Y-type filter 206 and the stop valve 203 is connected, and the liquid material dropwise addition operation can be performed. At this time, the second Y-type filter 211 is in a disconnected state, and the second Y-type filter 211 can be disassembled and cleaned. This operation will not affect the liquid material dropwise addition operation, so as to ensure the continuity of the production process.

[0044] In addition, it should be noted that: the first Y filter 206 is mainly to avoid the presence of solid impurities flow to the rotor flow meter 208, the first Y filter 206 of which the actual filtering of fixed impurities is less, so the first Y filter 206 can maintain long-term stable use, and the first Y filter 206 can be disassembled and cleaned during the factory rest.

[0045] The above merely provides a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
