Description

Technical Field

[0001] This utility model relates to the field of cleaning fluid production technology, and in particular to a passive pneumatic stirring and dispersing device for cleaning fluid. Background Technology

[0002] In the production process of cleaning fluid, it is necessary to stir and disperse the raw materials. There are usually two methods for stirring and dispersing cleaning fluid. The first is to use a stirring tank, which uses a stirring paddle in the stirring tank to stir and disperse the cleaning fluid. The second is pneumatic stirring, which blows compressed air into the cleaning fluid to generate bubbles in the cleaning fluid, driving the cleaning fluid to roll and achieve stirring and dispersion.

[0003] To prevent external air from entering the mixing tank, the agitator blades require a mechanical seal, which is costly. External compressed air contains impurities that can easily contaminate the cleaning fluid, necessitating improvements. Utility Model Content

[0004] The purpose of this invention is to provide a passive pneumatic stirring and dispersing device for cleaning fluid, which performs pneumatic stirring and dispersing to avoid pollution problems caused by the introduction of external air.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A passive pneumatic stirring and dispersing device for cleaning fluid includes: a dispersion tank, a piston, a one-way valve, and a cylinder. The dispersion tank is provided with a cover plate on top, the cylinder is provided at the bottom of the cover plate, the piston is vertically and vertically disposed in the cylinder, a sealing plate is provided at the bottom of the cylinder, and air blowing pipes that communicate with the cylinder and extend downward are provided at intervals at the bottom of the sealing plate. The one-way valves are provided at intervals on the lower part of the outer wall of the cylinder and communicate with the cylinder.

[0007] The cover plate is provided with a feeding port.

[0008] The dispersion tank is equipped with a discharge pipe joint at the bottom.

[0009] A valve is installed on the discharge pipe joint.

[0010] The cover plate is horizontally mounted with a motor, the motor shaft is vertically mounted with a turntable, the turntable is eccentrically mounted with a pin, the piston is mounted with a pin seat, and a connecting rod is mounted between the pin and the pin seat.

[0011] The cover plate is provided with a clearance groove corresponding to the connecting rod.

[0012] The beneficial effects of this utility model are as follows: A passive pneumatic stirring and dispersing device for cleaning liquid, when the piston moves down, sends the air below the piston in the cylinder into the air blowing pipe, and blows it into the cleaning liquid in the dispersion tank through the air blowing pipe, generating bubbles in the cleaning liquid, driving the cleaning liquid to roll, and realizing pneumatic stirring and dispersion. Moreover, there is no need for compressed air as an air source, avoiding the problem of introducing external air and causing contamination of the cleaning liquid. It is safer to use, has a simple structure, and low operation and maintenance costs. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model;

[0014] Figure 2 yes Figure 1 A schematic diagram of the structure after the second synchronous conveyor belt descends. Detailed Implementation

[0015] The following is combined Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0016] like Figure 1 The passive pneumatic stirring and dispersing device for cleaning liquid shown includes: a dispersing tank 1, a piston 8, a one-way valve 16, and a cylinder 3. The top of the dispersing tank 1 is provided with a cover plate 2, which can be fixed to the top of the dispersing tank 1 with screws. The structure is stable and easy to disassemble and assemble.

[0017] The cylinder body 3 is set at the bottom of the cover plate 2. In this embodiment, the cylinder body 3 and the cover plate 2 are concentric and can be fixed with screws, making the structure sturdy and avoiding the problem of the cylinder body 3 falling off the bottom of the cover plate 2.

[0018] The piston 8 is vertically mounted in the cylinder 3. In order to drive the piston 8 to move up and down, a motor 4 is horizontally mounted on the cover plate 2. A turntable 6 is vertically mounted on the shaft of the motor 4. The motor 4 drives the turntable 6 to rotate.

[0019] A pin 9 is eccentrically mounted on the turntable 6, and a pin seat 14 is mounted on the piston 8. A connecting rod 7 is provided between the pin 9 and the pin seat 14. The pin 9 changes its position and height as the turntable 6 rotates, thereby using the connecting rod 7 to pull the pin seat 14 and the piston 8 up and down.

[0020] like Figure 2 As shown, the cover plate 2 is provided with a relief groove 15 corresponding to the connecting rod 7. The connecting rod 7 will swing during the up and down pulling of the pin 9. The relief groove 15 is used to avoid interference when the connecting rod 7 swings.

[0021] Figure 1As shown, a sealing plate 13 is provided at the bottom of the cylinder body 3 to seal the bottom of the cylinder body 3. The cylinder body 3 and the sealing plate 13 adopt an integrated structure or a separate welded structure, which has high reliability. At intervals at the bottom of the sealing plate 13, there are air blowing pipes 5 that communicate with the cylinder body 3 and extend downward. The top of the air blowing pipes 5 is welded and fixed to the sealing plate 13 to prevent them from falling off.

[0022] A feeding port 10 is provided on the cover plate 2 for easy connection to a feeding mechanism, allowing the cleaning liquid raw material to be introduced into the dispersion tank 1. The cleaning liquid raw material is located below the tank body 3 and undergoes pneumatic stirring and dispersion. In this embodiment, a discharge pipe connector 11 is provided at the bottom of the dispersion tank 1, with an external pipe connected to the discharge pipe connector 11 for subsequent processing or filling. A valve 12 is provided on the discharge pipe connector 11; opening the valve 12 allows the stirred and dispersed cleaning liquid to be discharged through the discharge pipe connector 11.

[0023] like Figure 1 As shown, when piston 8 moves downward, the air below piston 8 in cylinder 3 is sent into air blowing pipe 5, which then blows into the cleaning liquid in dispersion tank 1. Bubbles are generated in the cleaning liquid, driving it to tumble and achieving pneumatic stirring and dispersion. The numerous air blowing pipes 5, with varying lengths, reach different depths into the cleaning liquid, resulting in a three-dimensional distribution of bubbles within the liquid, ensuring thorough tumbling and improving the uniformity of pneumatic stirring and dispersion.

[0024] To prevent the piston 8 from drawing in cleaning fluid when it moves upward, in this embodiment, the one-way valve 16 is spaced apart on the lower part of the outer wall of the cylinder 3 and communicates with the cylinder 3. When the piston 8 moves upward, the one-way valve 16 opens and draws in air above the cleaning fluid. There is no need for compressed air as an air source, which avoids the problem of introducing external air and causing contamination of the cleaning fluid, making it safer to use.

[0025] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
