Description

Technical Field

[0001] This utility model relates to the technical field of liquid raw material stirring devices, specifically to an automatic feeding liquid raw material stirring device. Background Technology

[0002] In many fields of industrial production, mixing liquid raw materials is a common and crucial step. Mixing achieves uniform mixing of different liquid raw materials, meets the requirements of production processes for material uniformity, and ensures stable product quality.

[0003] However, traditional liquid raw material mixing equipment has significant drawbacks. Regarding automated feeding, some equipment relies on manual feeding, which is labor-intensive and inefficient, making it difficult to meet the continuous demands of large-scale production. Even with automated feeding, the lack of precise liquid level monitoring and control often leads to inaccurate feeding amounts, affecting subsequent mixing and proportioning. In terms of mixing effect, the mixing blade design is simplistic, mostly simple paddle or anchor types, failing to adequately mix liquids at different levels. Dead zones often appear within the tank, resulting in uneven material mixing and ultimately affecting the stability and consistency of product quality. Utility Model Content

[0011] (III) Technical Effects

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1. A liquid level sensor monitors the liquid level in the storage tank in real time and transmits the signal to the controller. Based on the liquid level information, the controller precisely controls the opening and closing of the pump to ensure that the liquid level in the storage tank is always maintained at a suitable level, avoiding overfeeding or underfeeding, achieving precise automatic feeding, reducing manual intervention, and meeting the continuous needs of large-scale production.

[0025] Combined with appendix Figure 1 To be continued Figure 6An automatic feeding liquid raw material mixing device includes a mixing tank 1, with an inlet 2 at the top and an outlet 3 at the bottom. An outlet valve 4 is installed at the outlet 3. The mixing tank 1 is wrapped with an insulation layer 15 made of polyurethane foam. A storage tank 5 is connected to the upper end of the mixing tank 1, and an electromagnetic flow valve 6 is installed at the lower outlet of the storage tank 5. A mixing mechanism is installed inside the mixing tank 1. The device also includes an automatic feeding system, comprising a liquid pump 7, a feeding pipe 8, a liquid level sensor 9, and a controller 1. 0. One end of the pump 7 is connected to an external liquid source, and the other end is connected to the storage tank 5 through the feeding pipe 8. The liquid level sensor 9 is fixedly installed on the side wall of the storage tank 5. The electromagnetic flow valve 6, the liquid level sensor 9, and the pump 7 are all electrically connected to the controller 10. The stirring mechanism is set inside the stirring tank 1 and includes a stirring motor 11, a stirring shaft 12, and multiple sets of stirring blades. The stirring motor 11 is fixedly installed on the top of the stirring tank 1. The output shaft of the stirring motor 11 is fixedly connected to the top of the stirring shaft 12. Multiple sets of stirring blades are fixedly fixed along the axial direction on the stirring shaft 12.

[0026] In this embodiment, as a preferred technical solution, the multiple sets of stirring blades include a main stirring blade 13 and an auxiliary stirring blade 14. The main stirring blade 13 adopts a spiral blade and is fixed at the lower part of the stirring shaft 12. The auxiliary stirring blade 14 is horizontally fixed at the upper part of the stirring shaft 12, and multiple auxiliary stirring blades 14 are evenly distributed around the stirring shaft 12.

[0027] In this embodiment, as a preferred technical solution, a filter 16 is detachably connected to the feeding pipe 8 via a flange. The filter 16 includes a filter screen and a housing. The filter screen is installed inside the housing and is used to filter impurities in the liquid raw material.

[0028] The working principle of this automatic feeding liquid raw material stirring device is as follows: The device uses a liquid level sensor 9 to monitor the liquid level in the storage tank 5 in real time and feeds the signal back to the controller 10. The controller 10 then controls the pump 7 to operate, achieving automatic and precise feeding. The stirring motor 11 drives the stirring shaft 12 to rotate, causing the main stirring paddle 13 and auxiliary stirring paddle 14 to stir the liquid raw material in the mixing tank 1, achieving uniform mixing. The insulation layer 15 maintains a stable temperature inside the tank, and the filter 16 filters impurities to ensure the purity of the raw material.

[0029] The working process of the automatic feeding liquid raw material stirring device of this utility model is as follows:

[0030] 1. Preparation stage: Connect the external liquid raw material source to one end of the liquid pump 7, ensuring that all components are tightly connected and leak-free. Set the upper and lower limits of the liquid level sensor 9, the flow rate of the electromagnetic flow valve 6, and the stirring time and speed of the stirring motor 11 through the controller 10. The stirring motor 11 is also electrically connected to the controller 10.

[0031] 2. Automatic Feeding Stage: Upon startup, the level sensor 9 begins real-time monitoring of the liquid level in storage tank 5. When the liquid level falls below the set lower limit, the level sensor 9 sends a signal to the controller 10. Upon receiving the signal, the controller 10 starts the pump 7. The pump 7 draws external liquid raw materials into storage tank 5 through the feeding pipe 8. During the drawing process, the liquid raw materials pass through the filter 16, where the filter screen removes impurities, ensuring the purity of the raw materials entering storage tank 5. As liquid continuously enters, the liquid level in storage tank 5 rises. When the liquid level reaches the set upper limit, the level sensor 9 sends a signal to the controller 10 again, and the controller 10 stops the pump 7, completing one feeding cycle. The feed inlet 2 serves as a backup manual feeding port.

[0032] 3. Mixing Stage: Once the storage tank 5 contains sufficient raw material, the controller 10 opens the electromagnetic flow valve 6, allowing the liquid raw material in the storage tank 5 to flow into the mixing tank 1 through its lower outlet and connecting pipe. Feeding stops after a certain amount is reached, and then the controller 10 starts the mixing motor 11. The output shaft of the mixing motor 11 drives the mixing shaft 12 to rotate at high speed. The main mixing blade 13, located at the lower part of the mixing shaft 12, pushes the liquid at the bottom upwards due to its spiral blade structure, forming an axial circulating flow and initially mixing a large amount of liquid. Simultaneously, the auxiliary mixing blade 14, fixed to the upper part of the mixing shaft 12, performs transverse mixing of the upper liquid, enhancing the convection and mixing of the upper and lower liquids, eliminating dead zones, and ensuring uniform mixing of the liquid raw material.

[0033] 4. Discharge stage: After mixing is completed, open the discharge valve 4 at the discharge port 3, and the mixed liquid raw material is discharged from the discharge port 3 and enters the subsequent production process.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
