Description

Technical Field

[0001] The utility model belongs to the technical field related to mixing and stirring equipment, and in particular relates to a high-efficiency fiber mixing equipment. Background Art

[0002] Fiber blending equipment is a type of equipment used to blend different types of fibers or fibers with other raw materials. These equipment are often used in textile, fiber products and other related industries to ensure that the various components of the mixture are evenly distributed. Fiber blending equipment can adopt different working principles and designs, including stirring, mixing, extrusion, mixing drums, etc. The purpose of these equipment is to blend different types of fibers or other raw materials together in order to produce the desired material properties and characteristics during subsequent processing.

[0003] However, when the fiber mixing equipment mixes various fiber materials in a stirring manner, it is necessary to use a stirring roller to stir the various fiber materials inside the mixing tank until the various fiber materials are stirred and fully mixed. When the fiber materials are stirred, the shear force generated by the stirring will cause some fiber materials to adhere firmly to the inner wall of the mixing tank. When the mixing tank needs to be cleaned, relying on a high-pressure water gun to flush the inner wall of the mixing tank can only wash away normal dirt, while the residual fiber dirt firmly adhering to the inner wall of the mixing tank cannot be normally washed away by the high-pressure water gun. In this way, when the next batch of new fiber materials is mixed, the residual fiber dirt on the inner wall of the mixing tank will contaminate the new fiber materials, causing the new batch of fiber materials to fail to meet the processing requirements after mixing.

When the amount of fibers and other materials put into the mixing tank 2 reaches the production requirements, the feeding is stopped and mixing is prepared.

[0022] like Figure 1 and Figure 2As shown, the right end of the mixing shaft 9 is connected to the reducer 8 through a coupling, the right ends of the two placing pillars B4 are connected to the chassis frame 5, the bottom end of the reducer 8 is fixed to the top of the chassis frame 5 through a flange and screws, and the output shaft of the reducer 8 can drive the mixing shaft 9 to rotate clockwise or counterclockwise through the coupling. A transmission chassis 6 is fixed inside the chassis frame 5, and a transmission protective cover 7 is arranged outside the transmission chassis 6 and the right end of the reducer 8. A transmission motor is arranged inside the transmission chassis 6, and pulleys are arranged on the right end of the output shaft of the transmission motor and the right end of the input shaft of the reducer 8.

The fiber materials in the mixing tank 2 after mixing will be discharged through the discharge valve 3, so as to achieve the purpose of efficient mixing of the fiber materials.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, an inner wall scraper device 10 is arranged inside the top of the mixing tank 2, and the inner wall scraper device 10 includes a sealing sleeve 16, a U-shaped scraper frame 17, a scraper adjustment screw 18, a metal adjustment frame 21 and an adjustment screw hole 22. Two sealing sleeves 16 are provided, and the two sealing sleeves 16 are symmetrically fixed at the left and right ends of the mixing tank 2. The two sealing sleeves 16 are close to the top of the mixing tank 2. The scraper adjustment screw 18 is connected to the two sealing sleeves 16. The U-shaped scraper frame 17 is arranged inside the mixing tank 2. The metal adjustment frame 21 is connected to the inner wall at the front and rear ends of the top opening of the U-shaped scraper frame 17. An adjustment screw hole 22 is arranged inside the center of the metal adjustment frame 21. The adjustment screw hole 22 is threadedly sleeved on the outside of the scraper adjustment screw 18. The inner wall scraper device 10 also includes a U-shaped scraper The blade 14, the fixing ring A15, the adjusting handle 19 and the fixing ring B20, the fixing ring A15 is sleeved and fixed on the outside of the left end of the scraper adjusting screw 18, the fixing ring B20 is sleeved and fixed on the outside of the right end of the scraper adjusting screw 18, the adjusting handle 19 is arranged on the outer wall of the fixing ring B20, and the U-shaped scraper blade 14 is arranged on the outer walls on both sides of the center of the U-shaped scraper frame 17. The adjusting handle 19 can drive the scraper adjusting screw 18 to rotate clockwise or counterclockwise through the fixing ring B20. When the scraper adjusting screw 18 rotates clockwise or counterclockwise, it will push the metal adjusting frame 21 and the U-shaped scraper frame 17 to the left and right through the pushing action of the thread. The fixing ring A15 and the fixing ring B20 are respectively located on the outside of the two sealing sleeves 16 and play a role in limiting and fixing the position of the scraper adjusting screw 18.

When cleaning the mixing tank 2, it is first necessary to use clean water to rinse the inside of the mixing tank 2 to clean the dirt with weak adhesion inside the mixing tank 2, and then it is necessary to use the inner wall scraper device 10 to scrape off the dirt firmly attached to the inner wall of the mixing tank 2. Specifically, it is necessary to drive the scraper adjusting screw 18 to rotate through the adjusting hand lever 19 on the fixed ring B20, and the scraper adjusting screw 18 and the metal adjusting frame 21 are connected. The adjusting screw hole 22 at the top can drive the U-shaped scraper frame 17 to move left and right through the pushing action of the thread, and when the U-shaped scraper frame 17 moves from left to right from the inside of the mixing tank 2, the U-shaped scraper knife 14 on the outer wall of the U-shaped scraper frame 17 can scrape off the stubborn dirt attached to the inner wall of the mixing tank 2. When the U-shaped scraper frame 17 moves to the right and fits on the inner wall of the right end of the mixing tank 2, the scraper adjusting screw 18 will be blocked and cannot rotate. Then, the scraper adjusting screw 18 needs to be rotated in the opposite direction, which will push the U-shaped scraper frame 17 to the left, thereby scraping off the stubborn dirt attached to the inner wall of the mixing tank 2 again through the U-shaped scraper knife 14. In this way, the stubborn dirt firmly attached to the inner wall of the mixing tank 2 can be cleaned up, avoiding the situation that a lot of stubborn dirt remains in the mixing tank 2 after cleaning and affects the pollution of the next batch of fiber materials.
