DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] Please refer to Figures 1-4 , the present utility model provides a water-based additive mixing and preparation device, including an installation table 1 for installing the device, and a screening mechanism and a mixing mechanism are installed on both sides of the upper end of the installation table 1. The screening work and the mixing work are carried out simultaneously to avoid wasting working time separately. A feeding cylinder 3 is installed on the upper end of the installation table 1. A spiral auger 4 is connected inside the feeding cylinder 3 through a bearing. A first motor 6 is installed at the top end of the feeding cylinder 3 and is connected to the spiral auger 4. A material receiving port 5 is provided at the lower end of the feeding cylinder 3 and is connected to a discharge port 118. A discharge port 7 is provided at the upper end of the feeding cylinder 3 and is connected to a side material receiving port 11. In this way, the screened raw materials can be upwardly input into a converging box 10 at the upper end inside a mixing cylinder 8 when the first motor 6 drives the spiral auger 4 to rotate, so that the feeding can be carried out quickly, manual operation can be reduced, and the working progress can be accelerated.

[0031] The screening mechanism includes a screening box 2. A funnel-shaped discharge port 118 is provided at the bottom of the screening box 2 to facilitate the centralized downward treatment of raw materials and facilitate the discharging work. A filter cylinder 112 is installed inside the screening box 2 through a mounting plate 111. The filter cylinder 112 is of a filter screen type, so that it is convenient to screen out large particles in the raw materials and prevent the problem of insufficient mixing and preparation. A cover plate 113 covers the upper opening of the screening box 2, so that it is convenient to open the cover plate 113 to take out the internal filter cylinder 112 and clean impurities such as large particles inside. A feeding port 116 is installed outside the cover plate 113 for feeding work. A transmission rod 114 is connected to the middle of the cover plate 113 through a bearing. A crushing rod 115 is installed on the outside of the transmission rod 114. A third motor 117 is installed at the top end of the cover plate 113 and is connected to the transmission rod 114. The third motor 117 drives the transmission rod 114 to make the crushing rod 115 rotate to stir the raw materials, so that the screening speed of the raw materials inside the filter cylinder 112 is accelerated, and the large particles can be crushed, so as to avoid the subsequent crushing time and improve the working efficiency.

[0032] The mixing mechanism includes a mixing cylinder 8. A control panel 9 is installed outside the mixing cylinder 8 to make it more convenient for the staff to operate. And an upper converging box 10 is installed at the top section of the mixing cylinder 8 so that the raw materials and water first enter the inside of the upper converging box 10 for the first mixing. On both sides of the upper end of the upper converging box 10, there are respectively a side material receiving port 11 and a water inlet 12. And a solenoid valve can be set inside the water inlet 12 to facilitate the rate of water inflow, which is convenient for matching with the raw materials. At the bottom of the upper converging box 10, there is a funnel-shaped middle material discharging port 15, so that the raw materials and water enter the inside of the middle material discharging port 15. Inside the upper converging box 10, a rotating shaft 13 is connected through a bearing, and the rotating shaft 13 penetrates through the middle material discharging port 15 and the lower end of the mixing cylinder 8. Outside the rotating shaft 13, there are stirring rods 16 located inside the middle material discharging port 15 and the mixing cylinder 8, so that the rotating shaft 13 can drive the stirring rods 16 to rotate simultaneously inside the middle material discharging port 15 and the mixing cylinder 8 for mixing work. And the lengths of the stirring rods 16 arranged up and down inside the middle material discharging port 15 and the mixing cylinder 8 are different, so as to carry out stirring work at corresponding different positions. And the stirring rods 16 inside the middle material discharging port 15 are arranged in a staggered manner, and the stirring rods 16 are stacked up and down, so that the water and raw materials can collide with each other better when entering. And the bottom of the middle material discharging port 15 gradually becomes smaller, so that the mixing of the raw materials and water inside is increased, making the mixing effect better. A second motor 14 is installed at the top end of the upper converging box 10 and is connected to the rotating shaft 13, so that the second motor 14 generates driving force to facilitate the rapid rotation of the rotating shaft 13, avoiding manual rotation and accelerating the working speed. At the bottom of the mixing cylinder 8, there is a funnel-shaped bottom material discharging port 18 for convenient downward discharging, and a controllable valve 110 is installed inside the bottom material discharging port 18 so that the discharging can be manually controlled, which is convenient for controlling the mixing time.

[0033] Preferably, symmetrically connected to the inner wall of the mixing cylinder 8 inside the rotating shaft 13 is a scraper 17 in contact with it, so that during the rotation process, the scraper 17 can clean the mixed raw materials adhered to the inner wall of the mixing cylinder 8, avoiding the situation that it is difficult to clean the raw materials adhered to the inner wall later. And during the scraping process, the raw materials on the side can be concentrated, making the mixing effect better and avoiding the situation that there are blind spots on the side resulting in poor working effects.

[0034] Preferably, at the bottom end of the rotating shaft 13, there is a bottom auger 19 located inside the bottom material discharging port 18. Through the bottom auger 19, during the rotation process, the mixed raw materials can be quickly discharged, avoiding the situation that the raw materials block the bottom material discharging port 18, making the working effect better.

[0035] Working principle: When in use, first connect the first motor 6, control panel 9, second motor 14 and third motor 117 to an external power supply. Then pour the raw materials into the filter cylinder 112 inside the screening box 2 through the feeding port 116. The third motor 117 drives the transmission rod 114 to make the crushing rod 115 rotate, accelerating the screening of the raw materials, so that the raw materials enter the inside of the conveying cylinder 3 through the discharge port 118 and the material receiving port 5. When the first motor 6 drives the spiral auger 4 to rotate, the raw materials enter the upper converging box 10 through the side material receiving port 11. At the same time, the water inlet 12 first conveys water inside, so that the raw materials and water enter the middle material discharging port 15. When the second motor 14 drives the rotating shaft 13 to rotate, the stirring rod 16 stirs the raw materials on the stirring rod 16. After stirring, the raw materials enter the mixing cylinder 8 and are mixed again under the action of the stirring rod 16. And after the controllable valve 110 is opened, under the action of the bottom auger 19, the materials can be discharged downward, thus completing the work.
