[0027] like Figure 2 and Figure 3 As shown, the grinding structure 6 includes a first motor 61, the bottom of the first motor 61 is fixedly installed on the top of the shell 1, the output end of the first motor 61 extends to the inside of the shell 1, the output end of the first motor 61 is fixedly connected to a transmission rod 62, the right position of the top outer wall of the transmission rod 62 is rotatably connected to a grinding roller 63, the left position of the top outer wall of the transmission rod 62 is rotatably connected to a brush roller 64, the top of the inner cavity of the shell 1 is fixedly connected to a grinding disk 65, the bottom of the outer wall of the brush roller 64 and the bottom of the outer wall of the grinding roller 63 are both overlapped with the top of the grinding disk 65.

[0028] By setting the brush roller 64 and the grinding roller 63, the transmission rod 62 rotates, thereby driving the grinding roller 63 and the brush roller 64 to rotate synchronously. Under the cooperation between the grinding roller 63 and the grinding disk 65, the limestone milk raw material is ground, and the ground limestone powder passes through the grinding disk 65 and falls onto the surface of the filter 611. During this process, the brush roller 64 rotates to clean the surface of the grinding disk 65, thereby preventing some particles from clogging the small holes on the surface of the grinding roller 63, thereby affecting the discharge of the limestone powder.

[0029] like Figure 2 and Figure 3 As shown, an annular groove 68 is provided at the top of the inner wall of the shell 1, and a gear ring 67 is fixedly connected to the bottom end of the annular groove 68.

The external rotation of the two driven gears 66 that are close to each other is connected with a baffle 69, and the bottom end of the baffle 69 is located above the grinding disc 65.

[0030] By setting the driven gear 66 and the gear ring 67, while the brush roller 64 and the grinding roller 63 rotate, the driven gear 66 rotates on the surface of the gear ring 67.

The first transmission assembly 72 includes a first protective shell, a transmission belt and two transmission gears. The outer walls of the two transmission gears are meshed and connected with the inner wall of the transmission belt, and the transmission belt and the two transmission gears are located inside the first protective shell. The second motor 71 is fixedly installed on the left part of the front end of the first protective shell, and the output end of the second motor 71 is fixedly connected to the front end of the transmission gear located on the left, and the rear ends of the two transmission gears extend to the interior of the feed hopper 2. The rear ends of the two transmission gears are fixedly connected with crushing rollers 73, and the rear ends of the two crushing rollers 73 are respectively rotatably connected to the left and right sides of the lower position inside the feed hopper 2. Inclined plates 74 are fixedly connected to the left and right sides of the inside of the feed hopper 2, and the bottom ends of the two inclined plates 74 are respectively located above the tops of the outer walls of the two crushing rollers 73.

[0034] By setting the crushing roller 73, the second motor 71 drives the first transmission assembly 72 to work, and then drives the two crushing rollers 73 to rotate, so that the limestone can be preliminarily crushed before grinding, thereby relieving the grinding pressure of the grinding roller 63 and improving the processing efficiency of the grinding roller 63.

[0035] like Figure 6 As shown, the rear end of the left crushing roller 73 extends out of the rear end of the feed hopper 2, and the rear end of the feed hopper 2 is fixedly installed with a second transmission assembly 75, which includes a second protective shell, two transmission rollers and a toothed belt. The outer walls of the two transmission rollers are meshed and connected with the inner walls of the toothed belts, and the two transmission rollers and the toothed belts are located inside the second protective shell. The front end of the lower transmission roller is fixedly connected to the rear end of the left crushing roller 73, and the top of the feed hopper 2 is fixedly connected to a rectangular frame 76.

[0037] The working principle of the utility model is as follows: when in use, the fired limestone is put into the shell 1 through the feed hopper 2, and a certain amount of water is put into the shell 1 through the water inlet pipe 3, and the first motor 61 is started, thereby driving the transmission rod 62 to rotate, and then driving the grinding roller 63 and the brush roller 64 to rotate synchronously. Under the cooperation between the grinding roller 63 and the grinding disc 65, the limestone milk raw material is ground, and the ground limestone powder passes through the grinding disc 65 and falls on the surface of the filter 611. In this process, the brush roller 64 rotates to touch the surface of the grinding disc 65. The surface is cleaned to prevent some particles from clogging the small holes on the surface of the grinding roller 63, thereby affecting the feeding of limestone powder. When the brush roller 64 and the grinding roller 63 rotate, the driven gear 66 rotates on the surface of the gear ring 67. At the same time, under the meshing action of the two, the driven gear 66 rotates, thereby driving the grinding roller 63 and the brush roller 64 to rotate, thereby further improving the grinding and cleaning effects. At the same time, the baffle 69 can prevent the limestone raw material from falling into the annular groove 68, thereby affecting the meshing of the driven gear 66 and the gear ring 67, and the limestone powder falling After the surface of the filter screen 611 is filtered, the scraper 610 and the stirring blade 612 rotate with the transmission rod 62, and the limestone powder and the water are evenly mixed to form limestone milk. Thereafter, the limestone milk is discharged from the discharge pipe 4 by opening the first electromagnetic valve 5. In this process, the filter screen 611 filters out the larger limestone particles that do not meet the requirements. Thereafter, the second electromagnetic valve 613 can be opened to drive the scraper 610 to rotate. The scraper 610 slides the waste residue with larger particles to the slag discharge pipe 614 for further discharge to avoid the waste residue clogging the filter screen 611. In order to affect the filtering effect, during the limestone feeding process, the second motor 71 is started, which in turn drives the first transmission assembly 72 to work, and then drives the two crushing rollers 73 to rotate, thereby performing preliminary crushing on the limestone, relieving the pressure of the grinding roller 63, and thereby improving the processing efficiency of the grinding roller 63. While the grinding roller 63 is rotating, the second transmission assembly 75 is driven to work, thereby driving the reciprocating screw rod 77 to rotate, and then driving the dredging rod 78 to rotate back and forth, thereby moving the limestone raw material to prevent it from being blocked on the top of the two crushing rollers 73.
