Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, specifically a raw material mixing tank for the production of polypropylene plastic granules. Background Technology

[0002] The field of mixing tank technology revolves around the research, design, and application of material mixing equipment. Its core lies in optimizing the internal structure of the tank, the stirring components, and the control methods to achieve uniform mixing of materials in different forms (solid, liquid, and gas), while ensuring mixing efficiency and product quality. It integrates mechanical design, fluid mechanics, and automatic control technologies and is widely used in industries such as chemical, food, and pharmaceutical. Examples include raw material mixing in pharmaceuticals and sauce preparation in food processing. Key technical points include adaptability to different agitator types (paddle, ribbon, etc.), precise speed control, and adaptation to special working conditions such as aseptic / explosion-proof environments. It is a crucial support for improving production continuity and product consistency.

[0003] Chinese patent discloses a raw material mixing tank for the production of polypropylene plastic granules (authorization announcement number CN217318713U). This patented technology includes a base and a mixing tank. The mixing tank is positioned on top of the base, with elastic devices symmetrically installed on the left and right sides of the upper end of the base. A rotating shaft is installed on the right end of the mixing tank, passing through the elastic devices. A motor is installed on the right end of the rotating shaft, and a cam is installed on the outer surface of the rotating shaft. A fixed plate is positioned below the cam. A bearing is embedded in the left end of the mixing tank, and a fixed rod is installed inside the bearing. The fixed rod is rotatably connected to the mixing tank via the bearing, and the elastic device is fixedly connected to the left end of the fixed rod. This patented technology, by having the mixing tank and the stirring plate rotate in opposite directions, allows the raw materials to be quickly mixed and stirred, increasing the mixing efficiency. Simultaneously, the rotating shaft drives the cam to rotate, and the cam pushes the fixed plate, causing the mixing tank to vibrate through the elastic devices, further increasing the mixing efficiency of the raw materials within the mixing tank. However, this patented technology requires the mixing tank and the stirring plate to rotate simultaneously and in opposite directions to ensure thorough mixing of the raw materials, making the mixing tank unstable and posing a risk of damage. Therefore, those skilled in the art have provided a raw material mixing tank for the production of polypropylene plastic granules to solve the problems mentioned in the background art.

The inner and outer spiral ribbons are set in opposite directions, so the double-ribbon agitator will agitate a larger water vortex, so that the raw materials are fully mixed inside the main body. The mixing can be completed without the main body rotating itself, which improves the mixing efficiency.

[0013] 2. The three supports at the bottom of the main body are arranged in the shape of an equilateral triangle. Based on the stability of the triangle, the stability of the main body is improved, thus avoiding the risk of shaking during operation.

[0014] 3. After the discharge step is completed, the inside of the main body needs to be cleaned. First, pour clean water into the inside of the main body through the feed pipe, then open the valve to spray the cleaning agent into the inside of the main body through the nozzle. At this time, turn on the motor, which will drive the double ribbon agitator to rotate through the connecting shaft, thereby thoroughly cleaning the inside of the main body and greatly reducing the manual burden.

After pouring, the sealing cap 201 is replaced to ensure the airtightness of the device and prevent the raw material from being affected by external impurities. Then, the motor 104 is turned on to drive the connecting shaft 105 to rotate. The rotation of the connecting shaft 105 will drive the rotation of the rotating column 401, thereby putting the entire double-ribbon agitator 4 into a rotating state. The inner spiral ribbon 405 and the outer spiral ribbon 406 are set in opposite directions, so the double-ribbon agitator 4 will agitate a larger water vortex, so that the raw material is fully mixed inside the main body 1. The main body 1 does not need to rotate itself to complete the full mixing, which improves the mixing efficiency. The three supports 101 at the bottom of the main body 1 are set in the shape of an equilateral triangle. Triangles have stability, which ensures the stability of the device. After the mixing is completed, the staff places the receiving device at the output end of the discharge device 5 and then opens the valve 502 to collect the mixed raw material.

[0030] When the interior of the main body 1 needs to be cleaned, all the raw materials inside are first removed, and then clean water is poured into the interior of the main body 1 through the feed pipe 2. Then, valve 303 is opened so that the cleaning agent 3 is sprayed into the interior of the main body 1 through the nozzle 302. At this time, the motor 104 is turned on again, so that it drives the double ribbon agitator 4 to rotate again through the connecting shaft 105, thereby thoroughly cleaning the interior of the main body 1 and greatly reducing the manual burden.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
