[0030] A protective device is arranged on the support base 1;

[0031] The protective device includes a mounting base 7, a protective funnel 12 and a mixing tank 3. The mounting base 7 is fixedly connected to the upper surface of the mixing tank 3. A first motor 4 is fixedly connected to the upper surface of the mixing tank 3. One end of the mounting base 7 close to the mixing tank 3 fixedly extends into the interior of the mixing tank 3. A stirring shaft 16 is rotatably connected to the interior of the mixing tank 3.

Two sliding block grooves 5 are formed on the upper surface of the mounting base 7. The outer walls of the two guiding blocks at the lower end of the protective funnel 12 are respectively slidably connected to the interiors of the corresponding sliding block grooves 5. Sliding blocks 6 are slidably connected to the interiors of the two sliding block grooves 5. The fixing bolts threaded on the two sliding blocks 6 respectively threadedly extend into the interior of the sliding block grooves 5 and are respectively in contact with the inner walls of the corresponding sliding block grooves 5. The liquid leakage grooves formed on the protective funnel 12 are opposite to the liquid leakage grooves formed on the mounting base 7. A feeding pipe 10 is fixedly connected to the upper surface of the mixing tank 3, and the interior of the feeding pipe 10 communicates with the interior of the mixing tank 3.

[0032] Among them, the mixing tank 3 is fixedly connected to the upper surface of the support base 1. A fixing frame 2 is fixedly connected to the upper surface of the support base 1. The fixing frame 2 is in an inverted "U" shape. One end of the mixing tank 3 close to the support base 1 extends fixedly to the outside of the support base 1 and is equipped with a liquid outlet pipe. Two fixing plates on the opposite inner walls of the upper end of the fixing frame 2 are rotatably connected with a threaded rod 14. A limiting slider 15 is threadedly connected to the outer wall of the threaded rod 14. Two fixing rods 13 are fixedly connected to the opposite inner walls of the upper end inside the fixing frame 2.

[0033] Further, when using this device, it is started by connecting to an external power supply. First, the feeding pipe 10 is connected to an external device. Then, the external device transports raw materials into the mixing tank 3 through the feeding pipe 10. Then, the output end of the second motor 9 rotates to drive the threaded rod 14 to rotate, which drives the limiting slider 15 to move left and right and drives the liquid dispenser 17 to move left and right at the same time. Then, the liquid dispenser 17 is moved above the protective funnel 12. Then, the output end of the hydraulic telescopic rod 11 drives the liquid dispenser 17 to move downward so that the lower end of the liquid dispenser 17 enters the inside of the groove opened on the upper surface of the protective funnel 12. Then, the liquid dispenser 17 is controlled to quantitatively add additives and make them enter the inside of the mixing tank 3. While entering, it is protected by the protective funnel 12, which avoids the splashing of additives. Then, the output end of the first motor 4 rotates to drive the stirring shaft 16 to rotate and mix the raw materials and additives inside the mixing tank 3 at the same time. Then, when it is necessary to disassemble the protective funnel 12, turn the bolt on the sliding block 6 to rotate so that the other end of the bolt contacts the inner wall of the sliding block groove 5. Then, the sliding block 6 is taken out from the inside of the sliding block groove 5. Then, the protective funnel 12 can be taken off from the mounting seat 7.

[0034] The output end of the hydraulic telescopic rod 11 in the protection device drives the liquid dispenser 17 to move downward, so that the lower end of the liquid dispenser 17 enters the groove on the upper surface of the protection funnel 12. Then, the liquid dispenser 17 is controlled to quantitatively add additives into the mixing tank 3. While entering, the protection funnel 12 protects it, thus avoiding the splashing of additives, effectively improving the practicability of the equipment and avoiding the introduction of impurities or pollution that affect the subsequent production process and the quality of the final product. By turning the bolt on the sliding block 6 to rotate so that the other end of the bolt contacts the inner wall of the sliding block groove 5, then the sliding block 6 is taken out from the inside of the sliding block groove 5, and then the protection funnel 12 can be taken off from the mounting seat 7. This facilitates the disassembly of the protection funnel 12, improves the cleaning and maintenance efficiency of the protection funnel 12, and at the same time improves the flexibility of the equipment.

[0035] Working principle: First, connect the feed pipe 10 with an external device. Then, the external device conveys raw materials into the mixing tank 3 through the feed pipe 10. Then, the output end of the second motor 9 rotates to drive the threaded rod 14 to rotate, while driving the limit slider 15 to move left and right and driving the liquid dispenser 17 to move left and right. Then, the liquid dispenser 17 is moved above the protection funnel 12. Then, the output end of the hydraulic telescopic rod 11 drives the liquid dispenser 17 to move downward so that the lower end of the liquid dispenser 17 enters the groove on the upper surface of the protection funnel 12. Then, the liquid dispenser 17 is controlled to quantitatively add additives into the mixing tank 3. Then, the output end of the first motor 4 rotates to drive the stirring shaft 16 to rotate while mixing the raw materials and additives inside the mixing tank 3. Then, when the protection funnel 12 needs to be disassembled, turn the bolt on the sliding block 6 to rotate so that the other end of the bolt contacts the inner wall of the sliding block groove 5, then the sliding block 6 is taken out from the inside of the sliding block groove 5, and then the protection funnel 12 can be taken off from the mounting seat 7.
