Description

Technical Field

[0001] The invention belongs to the technical field of grinding, and in particular relates to high-efficiency grinding equipment for grinding cement clinker. Background Art

[0002] Portland cement clinker is a semi-finished product made from limestone and clay as the main raw materials, which are crushed, batched and ground into raw materials. It is then calcined in a cement kiln until it is partially or completely melted and cooled. Portland cement clinker grinding is an essential step in the production process of Portland cement clinker. Usually, workers directly pour the Portland cement clinker into the grinding device for grinding to obtain Portland cement powder. Currently, this technology has the following problems: Portland cement clinker usually contains large lumps of Portland cement clinker. Existing grinding equipment is difficult to grind large volumes of Portland cement clinker, causing the Portland cement clinker to accumulate in the grinding equipment, resulting in low grinding efficiency.

[0003] To this end, a high-efficiency grinding equipment for silicate cement clinker with the announcement number "CN217341635U" is disclosed, which includes a mounting frame, a crushing drum is rotatably arranged on the mounting frame, a crushing medium for crushing silicate cement clinker is arranged in the crushing drum, a grinding drum is rotatably sleeved on the outer side of the crushing drum, a grinding assembly for grinding the crushed silicate cement clinker is arranged in the grinding drum, and a connecting port for communicating with the grinding drum is opened on the side wall of the crushing drum. The crushed silicate cement clinker passes through the crushing filter plate and enters the grinding drum for grinding. After grinding, the silicate cement clinker that meets the requirements is discharged from the discharge port, and the silicate cement clinker that does not meet the requirements is more likely to collide and rub with the crushing medium in the crushing drum, thereby improving the grinding efficiency.

[0004] However, for the above-mentioned high-efficiency grinding equipment for silicate cement clinker, although the driven gear is engaged with the second gear ring to drive the grinding drum to rotate, so that the grinding roller in the grinding drum grinds the crushed silicate cement clinker, there are still the following obvious defects during use: the grinding roller is in contact with the inner wall surface of the grinding drum during the rotation of the grinding roller inside the grinding drum for grinding. Since there is no cleaning component for cleaning the inside of the grinding drum, part of the cement clinker will be squeezed and ground and stuck to the inner wall of the grinding drum during the grinding of the grinding roller. As a result, the connecting port and the surface of the crushing filter plate will be clogged after the grinding drum is used for a long time, which will affect the efficiency of cement clinker grinding and discharge. Summary of the Invention

[0011] Preferably, the bottom end of the vertical plate is fixed to the left side of the base end, and the A motor provided on the vertical plate is transmission-connected to one end of the driving shaft, so that the driving shaft will not be affected by the grinding cylinder when rotating.

[0012] Preferably, a lower hopper is provided at the bottom of the discharge cylinder, and a collecting box for collecting the ground cement clinker is provided at the corresponding bottom side of the lower hopper and at the end of the base, for allowing the last ground cement clinker to fall into the collecting box through the lower hopper.

The ground cement clinker falls into the grinding drum through the grinding mesh plate and enters the discharge drum through the grinding discharge mesh plate provided on the grinding drum. At the same time, the B motor starts to drive the A driving gear part to rotate, so that the A driving gear part drives the grinding drum to rotate inside the discharge drum through the meshing annular gear part, and the grinding roller rotates in contact with the inner wall of the discharge drum to grind the cement clinker for the second time, so that the quality of cement clinker grinding can be improved under the action of the second grinding, and at the same time, the grinding time can be reduced and the efficiency of cement clinker grinding production can be improved.

[0032] The cement clinker that has been ground for the first time is discharged through the sorting and grinding mesh plate 27, and the discharged cement clinker enters the inside of the grinding drum 3. At the same time, the B motor 15 rotates to drive the A driving gear 16 to rotate, and the A driving gear 16 engages to drive the ring gear 18 to rotate, and the ring gear 18 drives the grinding drum 3 to rotate, so that the cement raw materials remain in a moving state inside the grinding drum 3, allowing the cement clinker to pass through the grinding discharge mesh plate 26 more quickly and be discharged into the inside of the discharge drum 2, so that the cement clinker will not accumulate. The rotating grinding roller 17 of the grinding drum 3 is attached to the inner wall of the discharge drum 2 and rotates accordingly, thereby making the discharged cement clinker undergo a second grinding effect, further improving the quality of cement clinker grinding, and the secondary ground cement clinker falls into the discharge hopper 24 through the discharge mesh plate 28, and the ground cement clinker falls into the inside of the receiving box 25 through the discharge hopper 24 for collection, avoiding the ground cement clinker being scattered everywhere when discharged and difficult to collect.
