DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The utility model provides Figure 1-Figure 8 The calcium carbonate powder grinding device shown is easy to clean, comprising a grinding box 1, a feed hopper 2 is installed on the top of the grinding box 1, a discharge pipe 12 is connected to the bottom, and a grinding mechanism 3 is arranged on the grinding box 1;

[0030] The grinding box 1 is also provided with a cleaning mechanism 9 for cleaning the inside thereof, and the cleaning mechanism 9 includes a top blowing component, a bottom blowing component, and a dust collecting component 10 for collecting the powder blown up by the top blowing component and the bottom blowing component, wherein:

[0031] The top air blowing component includes an air distribution ring 93 installed at the top of the grinding box 1, and the bottom of the air distribution ring 93 is provided with evenly distributed air outlets 94;

[0032] The bottom blowing component comprises a blowing plate 95 fixed on the inner wall of the grinding box 1 , and one side of the blowing plate 95 has evenly distributed air outlet holes.

[0033] Specifically, the cleaning mechanism 9 also includes an air supply component, which includes a hair dryer 91 installed on the top of the grinding box 1, one end of the hair dryer 91 is connected to a three-way valve, and one end of the three-way valve is connected to an air supply main pipe 92, and the other end is connected to an air supply branch pipe 96, one end of the air supply main pipe 92 is connected to the air distribution ring 93, and one end of the air supply branch pipe 96 is connected to the blowing plate 95.

[0034] When grinding calcium carbonate powder, calcium carbonate powder is first added into the grinding box 1 through the feed hopper 2, and then the calcium carbonate powder is ground through the grinding mechanism 3. After grinding, the calcium carbonate powder is discharged through the discharge pipe 12 to obtain calcium carbonate powder with a desired particle size.

[0035] After grinding, air can be blown through the hair dryer 91, and under the action of the three-way valve, the air is diverted into the air supply main pipe 92 and the air supply branch pipe 96, and then the air supply main pipe 92 sends the air into the air distribution ring 93, and blows the air from top to bottom into the grinding box 1 through the air outlet nozzle 94, so that the residual powder in the grinding box 1 is blown to the bottom thereof. At the same time, the air supply branch pipe 96 sends the air into the blowing plate 95, and blows the air out through the air outlet hole to blow the powder at the bottom of the grinding box 1, and then the powder is sucked out and collected through the dust collecting component 10, so as to realize the cleaning of the grinding box 1, thereby facilitating the cleaning of the grinding device and facilitating the subsequent use of the grinding device.

[0036] Regarding how to collect powder as mentioned above, Figure 2 , Figure 4 and Figure 5 As shown:

[0037] The dust collecting component 10 includes a dust box 101 fixed on one side of the grinding box 1, and a collecting box 11 arranged below the dust box 101. An induced draft fan 102 and a separation plate 103 are installed in the dust box 101, and one side of the dust box 101 has exhaust holes, the separation plate 103 has filter holes, and the separation plate 103 is on the air inlet side of the induced draft fan 102. A drop opening is provided at the bottom of the dust box 101 for discharging powder blocked by the separation plate 103, and the drop opening corresponds to the collecting box 11.

[0038] When collecting powder, the powder at the bottom of the grinding box 1 can be sucked out by the induced draft fan 102, and the powder can be blocked by the separation plate 103, and the air is discharged through the filter holes, and then discharged to the outside through the exhaust holes under the action of the induced draft fan 102. Then the induced draft fan 102 stops working, so that the blocked powder falls into the collection box 11, thereby realizing the collection of powder and facilitating the recycling of calcium carbonate powder.

[0039] Regarding how to grind calcium carbonate powder, Figure 1-Figure 5 As shown:

[0040] The grinding mechanism 3 includes a grinding seat 33 fixed inside the grinding box 1. A grinding block 32 is arranged inside the grinding seat 33, and a grinding cavity is formed between the grinding block 32 and the grinding seat 33. A first motor 31 for driving the grinding block 32 to rotate is also installed at the top of the grinding box 1.

[0041] When calcium carbonate powder is added into the grinding box 1, the calcium carbonate powder will fall into the grinding chamber, and then the grinding block 32 is driven by the first motor 31 to rotate along the grinding chamber, and the calcium carbonate powder is ground with the cooperation of the grinding seat 33. After grinding, the calcium carbonate powder falls from the grinding chamber and is finally discharged through the discharge pipe 12, thereby completing the grinding of the calcium carbonate powder.

[0042] At the same time, in this embodiment, in order to improve the grinding effect, as Figure 1as well as Figure 3-Figure 5 As shown, the grinding box 1 is also provided with a screening mechanism 8 for screening the ground calcium carbonate powder, and the screening mechanism 8 includes a screen 81 arranged in the grinding box 1, and a second motor 83 fixed to one side of the grinding box 1, and an axle is rotatably installed inside the grinding box 1, and springs 84 are fixed on both sides of the inner wall of the grinding box 1, and the top of the spring 84 is connected to the bottom of the screen 81, and a cam 82 that can contact the bottom of the screen 81 is installed in the middle of the axle, and the second motor 83 is used to drive the axle to rotate, and a collecting box 7 is installed on one side of the grinding box 1, and a discharge hopper 6 for discharging powder on the screen 81 is connected between the collecting box 7 and the grinding box 1, and the screen 81 is located below the grinding seat 33.

[0043] When the ground calcium carbonate powder falls, it first falls on the screen 81. At this time, the shaft is driven to rotate by the second motor 83, so that the shaft drives the cam 82 to rotate, so as to drive the screen 81 to vibrate under the action of the spring 84, so as to screen the calcium carbonate powder, so that qualified calcium carbonate powder falls from the screen 81 and is discharged through the discharge pipe 12, while unqualified calcium carbonate powder rolls along the screen 81 under the vibration, so as to be discharged into the collection box 7 through the discharge hopper 6, thereby completing the screening of the calcium carbonate powder and facilitating the subsequent processing or use of the calcium carbonate powder.

[0044] Furthermore, if Figure 1-Figure 5 As shown, an elevator 4 is also installed on the collecting box 7, and a return hopper 5 is provided on the top of the grinding box 1. The feeding end of the elevator 4 is located in the collecting box 7, and the discharging end of the elevator 4 is located directly above the return hopper 5. Specifically, in this embodiment, the elevator 4 can adopt a vertical spiral elevator, and the structure and principle of the elevator are both existing technologies, which will not be elaborated here.

[0045] When unqualified calcium carbonate powder is discharged into the collection box 7, the calcium carbonate powder can be lifted by the elevator 4 and added into the grinding box 1 through the return hopper 5 to be ground again by the grinding mechanism 3 until the calcium carbonate powder falls through the screen 81 and is discharged, thereby facilitating the grinding of the calcium carbonate powder, ensuring the grinding effect, and further facilitating the subsequent processing or use of the calcium carbonate powder.

[0046] In addition, in one embodiment, if Figure 4 , Figure 5 and Figure 8 As shown, connecting strips 13 are installed on both sides of the top of the collecting box 11 , and connecting grooves matching with the connecting strips 13 are opened at the bottom of the dust collecting box 101 .

[0047] When the collection box 11 needs to be cleaned, the collection box 11 can be pulled so that the connecting strip 13 is moved out of the connecting groove, so that the collection box 11 can be disassembled from the bottom of the dust box 101, and then the powder collected in the collection box 11 can be poured out to facilitate the recovery of the powder, and the cleaning of the collection box 11 is completed. After cleaning, the collection box 11 can be plugged into the bottom of the dust box 101 through the cooperation of the connecting strip 13 and the connecting groove, and the installation of the collection box 11 is completed, thereby realizing the rapid disassembly and assembly of the collection box 11, facilitating the cleaning of the collection box 11, and facilitating the collection of powder.

[0048] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
