[0024] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.
[0025] The implementation of this utility model will now be described in detail with reference to the accompanying drawings.
[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of a chemical solution proportioning control device provided by this utility model includes a base 1, a support frame 2 fixedly installed on the top of the base 1, a container 3 provided on the top of the base 1, and a proportioning control component and a height adjustment component provided on the support frame 2.
[0027] The proportioning control assembly includes a movable frame 401, a one-in-two-out solenoid valve 402, a flow meter 403, a funnel 404, a feeding pipe 405, a residual material drain pipe 406, and a protective housing 407. The movable frame 401 is slidably connected to the inner side of the support frame 2. The one-in-two-out solenoid valve 402 is fixedly installed on the top of one end of the movable frame 401. The flow meter 403 is fixedly installed on top of the one-in-two-out solenoid valve 402. The funnel 404 is fixedly installed on top of the flow meter 403. The feeding pipe 405 and the residual material drain pipe 406 are both fixedly installed on the... At the bottom of the inlet-outlet solenoid valve 402, a protective housing 407 is fitted over the flow meter 403 and the inlet-outlet solenoid valve 402. The output end of the flow meter 403 is connected to the input end of the inlet-outlet solenoid valve 402, and the input end of the flow meter 403 is connected to the output end of the funnel 404. One end of the feed pipe 405 is connected to the first output end of the inlet-outlet solenoid valve 402, and one end of the residual material drain pipe 406 is connected to the second output end of the inlet-outlet solenoid valve 402. The top opening of the container 3 is located at the bottom of the output end of the feed pipe 405.
[0028] It should be noted that by setting up a one-in-two-out solenoid valve 402, which has one input end and two output ends, the flow rate of the solution is calculated by a flow meter 403. First, a threshold is set for the flow meter 403. Then, a funnel 404 is used, and the flow rate is detected by the flow meter 403. Then, the solution is discharged into the container 3 through the feed pipe 405 of the first output end of the one-in-two-out solenoid valve 402 for proportioning. During the proportioning process, when the solution reaches the required amount, the first output end of the one-in-two-out solenoid valve 402 closes and the second output end opens. The excess solution is discharged and recovered from the residual material drain pipe 406. No manual intervention is required, and the dosage is automatically controlled. In addition, the equipment is equipped with a PLC controller for controlling the operation of the equipment. The use of a PLC controller is a common method in the current electrification industry, which will not be elaborated here.
[0029] In some embodiments, such as Figure 1 , Figure 3 , Figure 4As shown, the height adjustment assembly includes an adjusting screw 501, a drive motor 502, a front pressure rod 503, a rear pressure rod 504, a normally open switch 505, and a return spring 506. The adjusting screw 501 is rotatably connected to the inside of the support frame 2. The drive motor 502 is fixedly installed on the top of the support frame 2. One end of the front pressure rod 503 is rotatably connected to the bottom side of the movable frame 401. The middle part of the rear pressure rod 504 is fixedly connected to one end of the front pressure rod 503. The normally open switch 505 is fixedly installed on the bottom side of the movable frame 401. The return spring 506 is fixedly installed between one end of the rear pressure rod 504 and the movable frame 401. The adjusting screw 501 and the movable frame 401 are threaded together. One end of the adjusting screw 501 is fixedly installed on one end of the output shaft of the drive motor 502. One end of the front pressure rod 503 is located at the top of the opening of the container 3. The side surface of one end of the rear pressure rod 504 abuts against the surface of the button of the normally open switch 505.
[0030] It should be noted that by setting a normally open switch 505, and setting a front pressure rod 503 and a rear pressure rod 504 as the starting structure of the normally open switch 505, when in use, the container 3 is placed on the base 1. At this time, the drive motor 502 drives the adjusting screw 501 to rotate and engage with the movable frame 401 to adjust the height of the movable frame 401. When the front pressure rod 503 touches the top of the container 3, the front pressure rod 503 causes one end of the rear pressure rod 504 to compress the return spring 506, and the other end causes the normally open switch 505 to no longer be pressed, and then it is opened. At this time, the drive motor 502 is de-energized, and the height of the proportioning control component is automatically adjusted according to the height of the container 3.
[0031] The drive motor 502 and normally open switch 505 in this utility model are known components and will not be described in detail here.
[0032] Working principle: During use, container 3 is placed on base 1. At this time, drive motor 502 drives adjusting screw 501 to rotate and engage with movable frame 401, adjusting the height of movable frame 401. When the front pressure rod 503 touches the top of container 3, the front pressure rod 503 causes one end of the rear pressure rod 504 to compress the return spring 506, and the other end causes the normally open switch 505 to no longer be pressed and then open. At this time, drive motor 502 is de-energized. According to the height of container 3, the height of the proportioning control component is automatically adjusted. Then, a threshold is set for flow meter 403. Then, funnel 404 is used, and flow is detected by flow meter 403. Then, the proportioning is discharged into container 3 through the feed pipe 405 of the first output end of one-in-two-out solenoid valve 402. During the proportioning process, when the solution reaches the required amount, the first output end of one-in-two-out solenoid valve 402 closes and the second output end opens. Excess solution is discharged and recovered from the residual material drain pipe 406. No manual intervention is required, and the dosage is automatically controlled.
