Description

Technical Field

[0001] The utility model relates to the technical field of Raymond mills, in particular to a Raymond mill with an anti-sticking wall function. Background Art

[0002] Raymond mill is mainly composed of main machine, analyzer, fan, finished product cyclone separator, micro powder cyclone separator and air duct. Among them, the main machine is composed of frame, air inlet volute, scraper, grinding roller, grinding ring and cover. The machine adopts the advanced structure of similar products at home and abroad, and is updated and improved on the basis of Raymond mill in the same industry. The equipment is more efficient, has lower power consumption, occupies less area and has less one-time investment than ball mill. When it is working, the material to be crushed is added into the machine from the feed hopper on the side of the machine cover. The grinding roller device hanging on the plum blossom frame of the main machine revolves around the vertical axis and rotates at the same time. Due to the centrifugal force during rotation, the grinding roller swings outward and presses against the grinding ring, so that the scraper scoops up the material and sends it between the grinding roller and the grinding ring. The purpose of crushing the material is achieved due to the rolling and rolling of the grinding roller.

[0003] In the prior art, when processing materials, due to the stickiness of the materials themselves, the formed powders are easy to adhere to the inner wall of the analyzer, which not only causes waste of materials and is inconvenient for subsequent cleaning, but also the thick powders attached inside will affect the negative pressure of the fan and cause the analyzer to shake violently. For this reason, we propose an anti-sticking Raymond mill to solve the above problems. Utility Model Content

[0039] The cleaning assembly includes: a rotating sleeve 15, two sliding tubes 17, two sliding rods 18 and two scrapers 20. The rotating sleeve 15 is rotatably sleeved on the transmission shaft 8. The bottom end of the rotating sleeve 15 passes through the top of the analyzer body 4 and extends to the inside of the analyzer body 4. The rotating sleeve 15 and the analyzer body 4 are rotatably connected through an axis. The ends of the two sliding tubes 17 close to each other are welded to the rotating sleeve 15. The ends of the two sliding rods 18 close to each other extend into the two sliding tubes 17 and are slidably connected to the inner walls of the sliding tubes 17. The ends of the two sliding rods 18 far away from each other are respectively welded to the top ends of the two scrapers 20.

[0040] The transmission assembly is arranged on the transmission shaft 8, and the transmission assembly is used to drive the scraper 20 to rotate.

[0041] By means of the above structure: by setting up a cleaning component, the inner wall of the analyzer body 4 can be scraped and cleaned, which can prevent the analyzed body 4 from sticking to the inner wall of the analyzer body 4 after molding due to the stickiness of the material itself when processing the material, thereby avoiding waste of material, reducing the cleaning frequency, and facilitating subsequent cleaning. At the same time, it can prevent the thicker powder attached to the inside of the analyzer body 4 from affecting the negative pressure of the fan 9, making the analyzer body 4 more stable during operation.

[0042] As a preferred solution of the utility model, the analyzer body 4 includes an outer shell 401 and a polypropylene inner shell 402. The outer shell 401 is fixedly mounted on the outside of the polypropylene inner shell 402. By setting the polypropylene inner shell 402, electrostatic adsorption of powder can be avoided, thereby reducing the adsorption of powder on the inner wall of the analyzer body 4.

[0043] As a preferred solution of the utility model, springs 19 are welded on the inner walls of the two sliding tubes 17 on the side close to each other, and the ends of the two springs 19 that are away from each other are respectively welded to the ends of the two sliding rods 18 that are close to each other.

At this time, the material is ground through the grinding cylinder 2, and then the ground material powder can drive the transmission shaft 8 and the fan 9 to rotate through the starting motor 7. At this time, the material powder will enter the analyzer body 4 through the wind pressure adsorption of the fan 9 for sorting. At this time, the qualified material powder will be discharged and collected through the discharge pipe 5. In addition, when the transmission shaft 8 rotates, the transmission between the two transmission wheels 10 and the transmission belt 11 can drive the rotating shaft 12 and the first gear 14 to rotate. At this time, the first gear 14 can drive the second gear 16, the rotating sleeve 15, the sliding pipe 17, The slide bar 18, the scraper 20 and the polypropylene plate 21 rotate, and the inner wall of the analyzer body 4 can be scraped and cleaned by the rotation of the scraper 20 and the polypropylene plate 21. The polypropylene plate 21 and the polypropylene inner shell 402 are provided to reduce static electricity generation, thereby reducing the adsorption of powder on the inner wall of the analyzer body 4. In this way, when the analyzer body 4 processes materials, the formed powder can be prevented from adhering to the inner wall of the analyzer body 4 due to the viscosity of the material itself, thereby avoiding waste of materials, reducing the cleaning frequency, and facilitating subsequent cleaning. At the same time, it can be avoided that the thick powder attached to the inside of the analyzer body 4 affects the negative pressure of the fan 9, making the analyzer body 4 more stable during operation.
