Description

Technical Field

[0001] This utility model relates to the technical field of liquid quantitative dispensing equipment, and more specifically, to a quantitative liquid dispensing device for a mixing tank. Background Technology

[0002] In many industries such as chemical, pharmaceutical, and food, it is often necessary to add various liquid raw materials to a mixing tank in precise proportions for mixing and stirring in order to produce products that meet quality requirements.

[0003] When adding water to the black and white mixture in the mixing tank, different weights of water are added according to different flavor settings. Existing liquid injection devices generally use visual water level markings and are manually shut off, which has poor accuracy and makes it difficult to control the stability of product production.

[0004] Therefore, we have made improvements to this and proposed a quantitative liquid injection device for a mixing tank. Utility Model Content

Existing liquid injection devices generally rely on visual water level markings and manual shut-off, which has poor accuracy and makes it difficult to control the stability of product production.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A metering liquid injection device for a mixing tank is provided to improve the above-mentioned problems.

The metering liquid injection assembly includes a fixing ring installed on the top of the top cover, an adjusting block slidingly fitted in the middle of the fixing ring, and multiple positioning pins that cooperate with the adjusting block are provided inside the fixing ring.

[0010] When injecting different amounts of water according to different tastes, the servo motor drives the rotating ring to rotate, causing the protrusions on the inner wall of the rotating ring to engage with the corresponding positioning pins and the positioning grooves on the side of the adjusting block. After a certain amount of water is injected into the injection tank, the piston plate drives the adjusting block to move upward, so that the positioning pins are inserted into the positioning grooves of the adjusting block to fix the position of the piston plate in the injection tank. This allows for adjustment of different injection amounts in the injection tank. The piston plate can be reset by a return spring.

[0035] Example 1

[0036] Please refer to Figure 1-6 A quantitative liquid injection device for a mixing tank includes: an injection tank 1, with an inlet pipe 2 and an outlet pipe 3 installed on the side and bottom of the injection tank 1, respectively; a top cover 7 installed on the top of the injection tank 1; a quantitative liquid injection assembly 8 installed on the top cover 7; the quantitative liquid injection assembly 8 includes a fixing ring 801 installed on the top of the top cover 7; an adjusting block 802 slidably engages with the middle of the fixing ring 801; and multiple positioning pins 806 cooperating with the adjusting block 802 are provided inside the fixing ring 801. Solenoid valves 4 are installed at the connections of the inlet pipe 2 and the outlet pipe 3 to the injection tank 1. A pressure gauge 5 is installed on the side of the injection tank 1, and a level gauge 6 is installed on the front of the injection tank 1. A piston plate 803 located inside the injection tank 1 is installed at the bottom of the adjusting block 802, and a return spring 804 is installed between the top of the piston plate 803 and the bottom of the top cover 7. The adjusting block 802 has multiple side openings with positioning grooves 807 that correspond to and cooperate with multiple positioning pins 806. The fixed ring 801 is rotatably fitted with a rotating ring 805. The inner wall of the rotating ring 805 is equipped with a protrusion 810 that cooperates with the positioning pins 806.

[0037] Implementation process: Liquid is introduced into the injection tank 1 through the water inlet pipe 2. During the injection process, the liquid level gauge 6 monitors the liquid level in the injection tank 1 in real time, and the pressure gauge 5 monitors the pressure in the tank. When injecting different amounts of water according to different tastes, the rotating ring 805 around the fixed ring 801 is rotated, so that the protrusion 810 on the inner wall of the rotating ring 805 drives the corresponding positioning pin 806 and the positioning groove 807 on the side of the adjusting block 802 to cooperate. After a certain amount of water is injected into the injection tank 1, the piston plate 803 drives the adjusting block 802 to move upward, so that the positioning pin 806 is inserted into the positioning groove 807 of the adjusting block 802 to fix the position of the piston plate 803 in the injection tank 1. Thus, different amounts of liquid can be injected into the injection tank 1. The piston plate 803 can be reset by the return spring 804.

[0038] Benefits of implementation: The amount of liquid injected into the injection tank 1 can be adjusted to different quantities.

[0039] Example 2

[0040] A servo motor 811 is mounted on the upper side of the top cover 7. A gear 812 is mounted on the output shaft of the servo motor 811. A gear ring 813 that meshes with the gear 812 is mounted on the circumference of the rotating ring 805. A through groove 808 that slides with the adjusting block 802 is opened on the upper side of the fixed ring 801. A convex groove 809 that slides with multiple positioning pins 806 is opened on the inner wall of the through groove 808. A first spring 814 is mounted on one end of the positioning pin 806. A moving post 815 that cooperates with the protrusion 810 is mounted on the other end of the first spring 814. A fixed plate 816 that slides with the inner wall of the convex groove 809 is mounted on the circumference of the moving post 815. A second spring 817 is mounted between one side of the fixed plate 816 and the inner wall of the convex groove 809.

[0041] Implementation process: By controlling the rotation direction and angle of the servo motor 811, the servo motor 811 drives the gear 812 to rotate. Since the gear 812 meshes with the gear ring 813 on the periphery of the rotating ring 805, the rotating ring 813 rotates. The protrusion 810 on the inner wall of the rotating ring 813 rotates to different directions and pushes the moving column 815 and the positioning pin 806 to move inward, so that the corresponding positioning pin 806 and the positioning groove 807 on the side of the adjusting block 802 cooperate, so that the positioning pin 806 is inserted into the positioning groove 807 of the adjusting block 802 to fix the position of the piston plate 803 in the injection tank 1. Through the fixing plate 816 and the second spring 817 set on the periphery of the moving column 815, when the protrusion 810 is not in contact with the moving column 815, the positioning pin 806 is located in the convex groove 809 by the force of the second spring 817.

[0042] Benefits of implementation: The amount of liquid injected into the injection tank 1 can be adjusted to different quantities.

[0043] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
