Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic storage tank equipment, and in particular to a plastic storage tank with a stirring function. Background Technology
[0002] Plastic storage tanks are containers made from polyethylene (PE), polypropylene (PP), or reinforced plastic (FRP) through rotational molding, blow molding, or winding processes. They have the following characteristics: corrosion resistance: they can store chemical media such as acids, alkalis, and salts, such as hydrochloric acid and sodium hypochlorite; lightweight and durable; insulating and antistatic; avoiding the risk of flammable liquids. In order to achieve efficient mixing of materials in the storage tank and meet diverse needs, a stirring structure is required.
[0003] Plastic storage tanks, with their advantages of corrosion resistance, light weight, and low cost, are widely used in many industries such as chemical, food, and pharmaceutical for material storage. However, traditional plastic storage tanks have a single function, only providing storage. When it is necessary to stir and mix the materials in the tank, the following problems exist: the stirring blades of traditional plastic storage tanks are in a fixed position, making it difficult to adjust the stirring range when storing materials at different liquid levels or stirring materials with different properties. When there is little or a lot of material in the tank, the fixed stirring blades cannot fully cover all the material, resulting in insufficient stirring and affecting the mixing effect. To address these issues, we propose a plastic storage tank with a stirring function. Utility Model Content
[0004] The purpose of this invention is to provide a plastic storage tank with a stirring function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A plastic storage tank with a stirring function includes a tank body. A drive motor is fixedly connected to the upper surface of the tank body. A rotating plate is fixedly connected to the output end of the drive motor. A circular cylinder is fixedly connected to the outer surface of the rotating plate. Multiple fixed circular cylinders are fixedly connected to the outer surface of the circular cylinder. Multiple main stirring blades are fixedly connected to the outer surface of each fixed circular cylinder. A long connecting rod is slidably connected inside each circular cylinder. The bottom ends of two long connecting rods are fixedly connected to a square moving plate. Multiple auxiliary stirring blades are fixedly connected to the outer surface of the square moving plate. An electric cylinder is fixedly connected to the inner wall of the circular cylinder. The output end of the electric cylinder is fixedly connected to the upper surface of the square moving plate. A cleaning component is fixedly connected to the outer surface of the circular cylinder.
[0007] In a further embodiment, an annular slide rail is fixedly connected to the inner top wall of the storage tank body, and two sliding blocks are slidably connected inside the annular slide rail, with the bottom surface of each sliding block being fixedly connected to the upper surface of the rotating plate.
[0008] In a further embodiment, a feeding pipe is provided on the upper surface of the storage tank body, and a discharge pipe is provided on the lower part of the outer surface of the storage tank body.
[0009] In a further embodiment, an observation window is provided on the outer surface of the tank body, and multiple bottom pads are fixedly connected to the bottom surface of the tank body.
[0010] In a further embodiment, the cleaning assembly includes two square connecting frames fixedly connected to the outer surface of the cylindrical tube. A transmission plate is fixedly connected to the outer surface of each square connecting frame, and a uniformly arranged cleaning brush strip is fixedly connected to the outer surface of each transmission plate.
[0011] In a further embodiment, each of the transmission plates has a diagonal brace fixedly connected to its outer surface, and the outer surface of each diagonal brace is fixedly connected to the outer surface of the square connecting frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This device uses an electric cylinder to drive a long connecting rod, which in turn drives the auxiliary stirring blades to slide up and down inside the cylindrical tank. The auxiliary stirring blades can be precisely adjusted to the appropriate position according to the material height inside the tank, ensuring that the stirring blades fully contact the material whether there is a small amount of material concentrated at the bottom or the tank is full. This achieves efficient stirring across the entire range and is suitable for stirring materials at different heights, improving the mixing effect. Furthermore, the main and auxiliary stirring blades work together. With the assistance of the drive motor, the main stirring blade rotates at a fixed height to stir the material, while the auxiliary stirring blade can be adjusted in height as needed. Together, they form a three-dimensional stirring pattern. For easily stratified plastic raw materials, this method can quickly break up the stratification, resulting in more uniform mixing and significantly improved mixing quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4In this utility model, a plastic storage tank with a stirring function includes a tank body 1. A drive motor 5 is fixedly connected to the upper surface of the tank body 1. A rotating plate 6 is fixedly connected to the output end of the drive motor 5. A circular cylinder 7 is fixedly connected to the outer surface of the rotating plate 6. Multiple fixed circular cylinders 14 are fixedly connected to the outer surface of the circular cylinder 7. Multiple main stirring blades 10 are fixedly connected to the outer surface of each fixed circular cylinder 14. A long connecting rod 15 is slidably connected inside each circular cylinder 7. The bottom ends of two long connecting rods 15 are fixedly connected to a square moving plate 12. The outer surface of the square moving plate 12... Multiple auxiliary stirring blades 13 are fixedly connected, and an electric cylinder 11 is fixedly connected to the inner wall of the cylindrical cylinder 7. The output end of the electric cylinder 11 is fixedly connected to the upper surface of the square moving plate 12, and a cleaning component 16 is fixedly connected to the outer surface of the cylindrical cylinder 7. This forms the core structure for tank stirring, enabling the drive motor 5 to drive the rotating plate 6, the cylindrical cylinder 7, and the main stirring blades 10 to rotate, thus achieving basic stirring. Meanwhile, the electric cylinder 11 drives the auxiliary stirring blades 13 to move up and down to meet the stirring requirements at different heights. Furthermore, the cleaning component 16 can clean the inner wall of the tank, improving the stirring effect and the cleanliness of the tank.
[0023] An annular slide rail 8 is fixedly connected to the inner top wall of the storage tank body 1. Two sliding blocks 9 are slidably connected inside the annular slide rail 8. The bottom surface of each sliding block 9 is fixedly connected to the upper surface of the rotating plate 6. The annular slide rail 8 and the sliding blocks 9 form a stable support and guiding structure, effectively limiting the shaking of the rotating plate 6 during rotation and stirring, ensuring the stirring blades rotate smoothly, improving the stability and reliability of the stirring, and guaranteeing the stirring quality. When the drive motor 5 drives the rotating plate 6 to rotate and stir at a high speed, the sliding blocks 9 slide smoothly within the annular slide rail 8, the rotating plate 6 always remains horizontal, and the rotation trajectory of the stirring blades is stable. A feeding pipe 3 is provided on the upper surface of the storage tank body 1. A discharge pipe 4 is provided on the lower part of the outer surface of the tank body 1. The feeding pipe 3 facilitates the rapid addition of materials into the storage tank, and the discharge pipe 4 can smoothly discharge the mixed materials. The reasonable arrangement of the two makes the operation of material entering and leaving the storage tank convenient and efficient, reduces material transportation time, and improves production efficiency. An observation window 2 is provided on the outer surface of the storage tank body 1, and multiple bottom pads 18 are fixedly connected to the bottom surface of the storage tank body 1. The observation window 2 allows the operator to observe the mixing status, liquid level, and material mixing of the materials in the storage tank in real time, so as to adjust the mixing parameters in time. The bottom pads 18 increase the contact stability between the storage tank and the ground, prevent the storage tank from shaking or shifting during mixing, and ensure the safe operation of the equipment.
[0024] The cleaning assembly 16 includes two square connecting frames 161 fixedly connected to the outer surface of the cylindrical cylinder 7. A transmission plate 162 is fixedly connected to the outer surface of each square connecting frame 161, and uniformly arranged cleaning brush strips 163 are fixedly connected to the outer surface of each transmission plate 162. As the cylindrical cylinder 7 rotates, the cleaning brush strips 163 of the cleaning assembly 16 continuously clean the inner wall of the storage tank, promptly removing materials adhering to the wall surface to prevent material accumulation from affecting the mixing effect and the service life of the storage tank, and reducing the frequency of manual cleaning. Each component is fixedly connected with a diagonal brace 17, and the outer surface of each diagonal brace 17 is fixedly connected to the outer surface of the square connecting frame 161. The diagonal brace 17 enhances the connection strength between the transmission plate 162 and the square connecting frame 161. When the cleaning brush 163 cleans the inner wall of the storage tank, even if it encounters greater resistance, it can ensure the stability of the cleaning component 16 structure, prevent the cleaning brush 163 from loosening or deforming, and ensure the cleaning effect. Due to the reinforcement effect of the diagonal brace 17, the transmission plate 162 and the square connecting frame 161 remain stable, so that the cleaning brush 163 does not bend or fall off.
[0025] The working principle of this utility model is as follows:
[0026] During mixing, the electric cylinder 11 can be extended according to the actual mixing height requirements, causing it to push the square moving plate 12 and the auxiliary stirring blade 13 to move up and down, and the long connecting rod 15 to slide inside the cylindrical cylinder 7. This adjusts the auxiliary stirring blade 13 to a suitable position. Then, the drive motor 5 can be started to rotate the rotating plate 6 and the cylindrical cylinder 7, causing the cylindrical cylinder 7 to rotate along with multiple main stirring blades 10 and the auxiliary stirring blades 13, thus mixing the material in all directions. This ensures that the stirring blades are in full contact with the material at all times. After mixing, the material is evenly mixed, making it suitable for mixing raw materials in different locations.
