[0018] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0019] like Figure 1 shown.

[0020] The present application discloses an operation method of a sand and gravel system for controlling the mud content of stone materials, comprising:

[0021] System Construction

[0022] A sand washing pool 1 containing mud, sand and gravel is provided, on which a sand washing machine 2 is installed, and at the discharge port of the sand washing machine 2 a belt conveyor A3 is installed.

[0023] It also includes a feed channel 4 with a mud volume detector 5 installed at the feed inlet, and the mud volume detector 5 detects the mud volume of the sand and gravel input into the feed inlet of the feed channel 4 by the conveyor A3. A channel partition 41 is installed in the middle of the channel channel 4, and a swingable diverter plate 42 is connected to the channel partition 41. The diverter plate 42 is controllably swingable by a motor or other equipment. The mud volume detector 5 is composed of a camera to collect images of the mud content.

[0024] Belt conveyors B6 and C7 are installed on both sides of the outlet of the distribution channel 4. The belt conveyor B6 can convey the sand and gravel with a relatively high mud content to the sand washing pool 1; the belt conveyor C7 can convey the sand and gravel with a qualified mud content to the crusher 8, and crush them together with the raw stone conveyed by the belt conveyor D9.

[0025] System Operation

[0026] The sand washer 2 cleans the sand and gravel in the sand washing tank 1, and the belt conveyor A3 conveys the cleaned sand and gravel to the material distribution channel 4. The mud detector 5 detects the mud content of the sand and gravel input by the conveyor A3 into the material distribution channel 4; when it is detected that the mud content of the sand and gravel is still high, the diverter plate 42 swings to the right, and the sand and gravel are discharged to the belt conveyor B6 through the left channel of the material distribution channel 4. The belt conveyor B6 conveys the sand and gravel with high mud content back to the sand washing tank 1, and then the sand washer 2 performs secondary cleaning on the sand and gravel in the sand washing tank 1. The problem of high mud content after one cleaning is solved.

[0027] When the sand washing machine 2 cleans the sand and gravel in the sand washing pool 1, the belt conveyor A3 conveys the cleaned sand and gravel to the distribution channel 4, and the mud detector 5 detects the mud amount of the sand and gravel input by the conveyor A3 into the feeding port of the distribution channel 4; when it is detected that the mud content of the sand and gravel exceeds the standard by a low amount, the diverter plate 42 swings to the left, and the sand and gravel are discharged to the belt conveyor C7 through the right channel of the distribution channel 4, and the speed of the belt conveyor C7 is controlled to increase. The belt conveyor C7 conveys the sand and gravel with a qualified mud content to the crusher 8, and crushes them together with the raw material stone conveyed by the belt conveyor D9; at this time, a small amount of sand and gravel with a low mud content exceeding the standard is crushed with the raw material stone in the crusher 8, and the secondary cleaning of the sand and gravel is reduced on the premise that the mud content of the crushed sand and gravel does not exceed the standard. At the same time, the sand and gravel with a low mud content exceeding the standard are mixed with the raw material stone in the crusher 8 for crushing, which can reduce the impact on the crusher 8.

[0028] When the sand washing machine 2 cleans the sand and gravel in the sand washing pool 1, the belt conveyor A3 conveys the cleaned sand and gravel to the distribution channel 4, and the mud amount detector 5 detects the mud amount of the sand and gravel input by the conveyor A3 into the feeding port of the distribution channel 4; when it is detected that the mud content of the sand and gravel is qualified, the diverter plate 42 swings to the left, and the sand and gravel are discharged to the belt conveyor C7 through the right channel of the distribution channel 4. The belt conveyor C7 conveys the sand and gravel with qualified mud content to the crusher 8, and crushes them together with the raw stone conveyed by the belt conveyor D9.
