[0019] 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.
[0020] See Figures 1-4As shown, it includes an outer frame 1, with a feeding trough 2 at the top and a discharge pipe 3 connected to the bottom of the feeding trough 2. The discharge pipe 3 has an internal equalization structure, which is connected to four premix tanks 4 located below it, ensuring that the material enters each premix tank 4 evenly. In addition, a main mixing tank 5 is located at the bottom of the outer frame 1. The bottom of all the premix tanks 4 is connected to the main mixing tank 5 through a premix discharge pipe 11, so that the premixed material can smoothly enter the main mixing tank 5 for further mixing.
[0021] The core component of the equal distribution structure is the equal distribution block 18 located at the bottom of the feed pipe 3. The equal distribution block 18 is a square pyramid shape, and each edge of its bottom is an inwardly concave arc shape. Each corner of the bottom surface of the equal distribution block 18 is connected to the inner wall of the feed pipe 3. At the same time, each edge of the bottom of the equal distribution block 18 and the edge of the bottom of the inner wall of the feed pipe 3 together form an arc-shaped channel. Each arc-shaped channel is connected to a distribution pipe 19, and the bottom ends of these distribution pipes 19 are respectively connected to the premix tank 4 below, so that the material can smoothly enter each premix tank 4, ensuring the uniformity and stability of the mixing process. The feed pipe 3 is provided with a funnel-shaped guide hopper 17.
[0022] Above the outer frame 1, a premixing motor 6 and a premixing reducer 7 are installed to provide power support for premixing. Each premixing tank 4 is equipped with a rotatable premixing shaft 9, and multiple sets of premixing blades 10 are arranged on the premixing shaft 9 to ensure that the materials are fully mixed in the premixing tank. The power output end of the premixing reducer 7 is connected to one of the premixing shafts 9 through a coupling, and the four premixing shafts 9 are connected by a sprocket assembly 8 to ensure that all the premixing shafts 9 can operate synchronously.
[0023] At the center of the main mixing tank 5, a main mixing shaft 15 is rotatably installed. The main mixing shaft 15 is equipped with multiple sets of main mixing blades 16, which enable the materials from the premixing tank 4 to be fully mixed in the main mixing tank 5. A main mixing motor 13 and a main mixing reducer 14 are connected to the main mixing tank 5. The output shaft of the main mixing reducer 14 is connected to the main mixing shaft 15, providing stable power support for the mixing process of the main mixing tank 5, thereby achieving deep mixing of materials.
[0024] In addition, at the bottom of the main mixing tank 5, there are multiple discharge pipes 20 with valves, which allow the material after mixing to be discharged smoothly to meet production needs. At the same time, each premixed discharge pipe 11 is equipped with a premixed discharge valve 12 to control the discharge of premixed material in the premixed tank 4 to the main mixing tank 5, thereby achieving precise batching and efficient mixing.
[0025] The principle and usage process of this utility model:
[0026] First, start the device and pour the materials to be mixed into the feed trough 2. As the materials flow downward, they pass through the guide hopper 17, are concentrated, and fall to the tip of the top of the equalizing block 18. They then flow downward evenly along the four sides of the equalizing block 18 and flow into the premix tank 4 through the distribution pipe 19. The premix motor 6 drives the premixing shaft 9 to rotate through the premix reducer 7. Then, the premixing blades 10 rotate to premix the materials in the premix tank 4. After premixing in the premix tank 4 for a period of time, open the premix discharge valve 12 to discharge the materials in the four premix tanks 4 downward into the main mixing tank 5. After closing the premix discharge valve 12, materials can be added to the feed trough 2 again.
[0027] The main mixing motor 13 drives the main mixing shaft 15 to rotate through the main mixing reducer 14. The main mixing blades 16 mix the premixed materials, making the materials quickly and evenly mixed. Then the valve can be opened to discharge the materials from the discharge pipe 20. At the same time, the premixing above can also work simultaneously to speed up the mixing efficiency.
[0028] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
