[0006] A filter pipe, one end of which is connected to the grinding chamber, and the other end extends outside the grinding chamber. Moreover, a first screen is installed at the end of the filter pipe extending into the grinding chamber;

[0007] A discharge channel, installed on the pipe wall of the filter pipe, for discharging the slurry in the grinding chamber;

[0008] An air pipe joint, installed at the end of the filter pipe away from the grinding chamber, for passing high-pressure gas through the filter pipe, passing through the first screen and entering the grinding chamber to flush away the blockage on the first screen;

[0009] A discharge pipe, one end of which is communicated with the grinding chamber, and the other end is connected to a storage bucket, and the storage bucket is used for storing the high-pressure gas and the blockage of the air pipe joint;

[0023] The names of the messages or information exchanged between multiple devices in the embodiments of this application are only for illustrative purposes and are not used to limit the scope of these messages or information.

[0024] Refer to Figure 1 and Figure 2 , a grinding device convenient for dredging, including a grinding chamber 10, and the grinding device further includes:

[0025] A filter pipe 20, one end of which is connected to the grinding chamber 10, and the other end extends outside the grinding chamber 10. Moreover, a first screen 21 is installed at the end of the filter pipe 20 extending into the grinding chamber 10.

[0026] A discharge channel 22 is installed on the pipe wall of the filter pipe 20. The grinding chamber 10 is filled with pick balls and slurry. After grinding is completed, the slurry passes through the first screen 21 and is discharged through the discharge channel 22 from the filter pipe. At this time, it is in the normal grinding state.

[0027] An air pipe joint 23 is installed at the end of the filter pipe 20 far from the grinding chamber 10, and is used to pass gas through the filter pipe, pass through the first screen 21 and enter the grinding chamber 10. When the first screen 21 is blocked, the air pipe joint 23 will fill the filter pipe 20 with high-pressure gas, and the high-pressure gas impacts the first screen 21 to remove the blockage hanging on the first screen 21. Specifically, the impact direction of the high-pressure gas is from the side of the first screen 21 far from the grinding chamber 10 to the side close to the grinding chamber 10, as Figure 2 shown by the dotted arrow in the grinding chamber 10 in the figure. At this time, it is in the cleaning state.

[0028] The grinding device further includes a discharge pipe 30, one end of which is communicated with the grinding chamber 10, and the other end is connected with a storage barrel 31. The storage barrel 31 is used for storing the gas of the gas pipe joint 23. The end of the discharge pipe 30 extending into the grinding chamber 10 is provided with a second screen 32. After the plug is removed by the high-pressure gas, the high-pressure gas together with the plug will enter the discharge pipe 30 through the second screen 32 and enter the storage barrel 31 through the discharge pipe 30 to collect sundries. Preferably, the aperture of the second screen 32 is larger than that of the first screen 21.

[0029] Further improvement based on the above structure: The grinding device further includes a valve group for separately opening or closing the discharge channel 22, the filtering pipeline 20 or the discharge pipe 30. Specifically, the valve group includes: a first valve 41 installed on the discharge pipe 30 for opening or closing the discharge pipe 30; a second valve 42 installed on the discharge channel 22 for opening or closing the discharge channel 22; a third valve 43 installed on the filtering pipeline 20 for opening or closing the filtering pipeline 20.

[0030] In the normal grinding state, the first valve 41 and the third valve 43 are closed to prevent the slurry from flowing out of the discharge pipe 30 or entering the gas pipe joint 23. As Figure 1 shown, the position of the third valve 43 should be between the discharge channel 22 and the gas pipe joint 23.

[0031] In the cleaning state, the second valve 42 opens the third valve 43 and the first valve 41, so that the high-pressure gas can enter the grinding chamber 10 and then be discharged from the discharge pipe 30.

[0032] As a further improvement of the above structure, in order to ensure that the gas maintains a high-pressure state when entering the grinding chamber 10, as Figure 2 shown, the axis of the filtering pipeline 20 is coaxially arranged with the axis of the gas pipe joint 23, which can make the gas maintain a high-pressure state. And the extending direction of the discharge channel 22 is perpendicular to the extending direction of the filtering pipeline 20 to avoid the flow of the gas.

[0033] Further improvement based on the above structure: The first screen 21 is of a cylindrical structure and extends along the axis of the filtering pipeline 20 into the grinding chamber, which can increase the filtering area. Further, there is a support frame 211 inside the first screen 21 to keep the first screen 21 in a cylindrical structure and prevent it from deforming under the impact of the slurry.

[0034] Specifically, as Figure 3As shown, the support frame 211 includes: a first circular ring frame 2111; installed inside the first screen 21, specifically, at the bottom inside the first screen 21; a second circular ring frame 2112; installed at the opening of the first screen 21, and the outer edge of the second circular ring frame 2112 is fixed to the inner edge of the second screen 32; further, the support frame 211 further includes: the support frame 211 is connected to the filter pipe 20 through the second circular ring frame 2112; further, the support frame 211 further includes: a support rod 2113, with both ends threadedly connected to the first circular ring frame 2111 and the second circular ring frame 2112 respectively. During installation, the first circular ring frame 2111 needs to be installed at the bottom inside the first screen 21, then the support rod 2113 is screwed onto the first circular ring frame 2111, and then the second circular ring frame 2112 is installed at the other end of the support rod 2113. The user can reach in through the perforation in the middle of the second circular ring frame 2112 to rotate the support rod 2113.

[0035] Further, the inner ring of the second circular ring frame 2112 has a first thread groove 2114; the end of the filter pipe 20 extending into the grinding chamber 10 is provided with an annular groove, and the inner wall of the filter pipe 20 in the annular groove is provided with a second thread groove 24; the first thread groove 2114 cooperates with the second thread groove 24 so that the second circular ring frame 2112 can be screwed onto the filter pipe 20 to facilitate the installation of the first screen 21.

[0036] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0037] Those skilled in the art should understand that the above embodiments are only for clearly explaining the present application, rather than limiting the scope of the present application. For those skilled in the art, other changes or variations can be made based on the above disclosure, and these changes or variations are still within the scope of the present application.
