Description

Technical Field

[0001] This utility model relates to the field of chemical production, and in particular to a water-to-alcohol ratio stabilization control device with a voltage-stabilizing bypass. Background Technology

[0002] In chemical production and other fields, the water-ethanol mixture is widely used in key processes such as raw material dissolution, extraction, and reaction medium preparation. The precise control of its mixing ratio directly determines the product purity, reaction efficiency, and final quality stability.

[0003] In the extraction process of effective components of traditional Chinese medicine, solvents with a specific water-to-ethanol ratio can improve the yield of target components. In the production of disinfectants, the ethanol concentration needs to be stabilized in the range of optimal bactericidal effect by precisely controlling the water-to-ethanol ratio. In order to achieve effective control of the water-to-ethanol ratio, water and ethanol are often quantitatively delivered to a mixing container and stirred.

[0004] However, conventional water-to-alcohol ratio control devices still have shortcomings in actual use. The quantitative feeding mechanism of most devices is generally controlled by a flow pump, which makes the amount of material conveyed susceptible to fluctuations in the raw material conveying pressure and flow rate, resulting in deviations in the amount of material fed in a single batch. This leads to the water-to-alcohol ratio deviating from the set value, affecting subsequent use. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water-alcohol ratio stabilization control device with a pressure-stabilizing bypass. It aims to improve the problem that conventional water-alcohol ratio control devices in the prior art rely on flow pumps to control quantitative feeding, which is easily affected by fluctuations in raw material conveying pressure and flow rate, resulting in deviations in the amount of material fed at one time and deviations in the water-alcohol ratio from the set value, thus affecting subsequent use.

A discharge pipe 4 is connected through and fixedly connected to the mixing tank 1. The finished product after mixing is discharged from the discharge pipe 4. The discharge pipe 4 is located in the middle of the lower surface of the mixing tank 1. A pressure regulator 6 is provided on the left surface of the mixing tank 1.

[0023] Reference Figures 2-4 Gear 1 92 meshes with two sets of gears 2 93, and the two sets of gears 2 93 move at the same frequency. The voltage regulator 6 is electrically connected to the motor 91. The voltage regulator 6 can stabilize the voltage and ensure the stable operation of the motor 91. The middle part of the guide plate 98 is set to be hollow through the left and right. The positioning rod 97 slides on the inner wall of the guide plate 98. The upper and lower ends of the positioning rod 97 contact the upper and lower sides of the inner surface of the guide plate 98. When the positioning rod 97 moves around the center circumference of the connecting rod 94, it will squeeze the guide plate 98 and drive the guide plate 98 to move up and down reciprocally.

[0024] Reference Figure 2 , Figure 4 , Figure 5The adjusting component 10 includes a groove 101, which is formed on the right surface of the positioning plate 96. A fastener 102 is threadedly connected to the inner surface of the disc 95. An extruder 103 is sleeved on the outer wall of the fastener 102.

[0025] Reference Figure 2 , Figure 4 , Figure 5 Fastener 102 penetrates the right surface of disc 95 and the inner wall of groove 101. The left surface of extruder 103 and the right surface of positioning plate 96 are attached. The positioning plate 96 can be limited by the extrusion of extruder 103.

[0026] Working principle: Before the device is put into operation, the water and ethanol addition ratio is preset by adjusting component 10. During adjustment, the fastener 102 on the disc 95 is loosened, and the positioning plate 96 is slid along the groove 101 to adjust the relative position of the positioning plate 96 and the disc 95, so as to adjust the circumferential movement radius of the positioning rod 97. After determining the ratio, the fastener 102 is tightened so that the extrusion part 103 is attached to the right surface of the positioning plate 96 to complete the fixation.

[0027] Furthermore, the connecting pipes 82 of the two sets of quantitative feeding components 8 are respectively connected to the external water tank and ethanol tank, the valve of the discharge pipe 4 is kept closed, and the voltage regulator 6 is powered on to provide a stable voltage for the motor 91.

[0028] Then the device can be used. When in use, start the motor 91 and the stirring device 5. The output shaft of the motor 91 drives the gear 1 92 to rotate. The gear 1 92 meshes and drives the two sets of gears 2 93 to rotate at the same frequency. The gears 2 93 drive the disc 95 to rotate through the connecting rod 94. The positioning plate 96 on the disc 95 moves in a circular motion with it. The positioning rod 97 slides on the inner wall of the guide plate 98 and squeezes the guide plate 98, so that the guide plate 98 drives the sliding rod 86 and the sealing gasket 87 to move up and down along the inner wall of the feeding tank 81. When the sealing gasket 87 moves up, a negative pressure is generated in the feeding tank 81, which can suck the external raw materials into the feeding tank 81 through the connecting pipe 82. When the sealing gasket 87 moves down, it will squeeze the raw materials in the feeding tank 81. The raw materials are pressed into the stirring tank 1 through the feed pipe 84. The stirring device 5 mixes the water and ethanol entering the stirring tank 1. The gas produced by the reaction is discharged through the exhaust pipe 3. After the mixing is completed, open the valve of the discharge pipe 4. The finished product is discharged from the discharge pipe 4 along the inner wall of the bottom of the stirring tank 1.
