The coarsely crushed stone is sent to the cone crusher (or impact crusher) by the belt conveyor for medium crushing. The medium crushed stone is sent to the vibrating screening machine by the belt conveyor for screening. The finished sand (screened material) is sent to the sand washing machine for cleaning by the belt conveyor and then sent to the finished material pile by the belt conveyor.

The end of the air inlet channel 402 located outside the dust removal chamber body 102 is in a square structure, and the end of the air inlet channel 402 located inside the dust removal chamber body 102 is in a rectangular structure, and the two ends of the air inlet channel 402 have a smooth transition; the angle between the bottom of the air inlet channel 402 and the horizontal direction is greater than the angle between the top of the air inlet channel 402 and the horizontal direction. The receiving plate 602 is located directly below the second feed port 702.

[0041] The dust removal chamber body 102 has an air inlet channel 402 at the lower part of one end in the horizontal direction, and an air outlet channel 502 at the upper part of the other end in the horizontal direction. The end of the air inlet channel 402 connected to the dust removal chamber body 102 extends to the inside of the dust removal chamber body 102. The top of the dust removal chamber body 102 is provided with a second feed port 702 near the side of the air inlet channel 402, and the bottom of the dust removal chamber body 102 is provided with a plurality of strip-shaped discharge holes 802; the fan 202 has an air supply duct, which is connected to the air inlet channel 402, and the plurality of impacted strips 302 are evenly distributed and fixed inside the dust removal chamber body 102.

The fan 202 adopts a Roots blower, which has a stronger wind force and can ensure that the fine stones are blown to the impacted strip plate 302. The end of the air inlet channel 402 located outside the dust removal chamber body 102 is in a square structure, and the end of the air inlet channel 402 located inside the dust removal chamber body 102 is in a rectangular structure, and the two ends of the air inlet channel 402 have a smooth transition; the angle between the bottom of the air inlet channel 402 and the horizontal direction is greater than the angle between the top of the air inlet channel 402 and the horizontal direction.

After the stone comes out of the second discharge port 1002, it falls into the fine material vibration screening machine 6 for further screening.

[0042] The dust-containing gas inside the dust-containing gas main pipeline 7 is sent to the settling chamber 9 through the main dust extraction fan 12 and passes through the cyclone dust collector 10 and the dust-containing gas purification chamber 11 in sequence. The stone powder dust in the dust-containing gas is collected by the settling chamber 9 and the cyclone dust collector 10, but part of the gas discharged from the cyclone dust collector 10 is still not collected by the cyclone dust collector 10. Subsequently, the gas discharged from the cyclone dust collector 10 is further purified through the dust-containing gas purification chamber 11.

[0043] like Figure 8-Figure 10 As shown, the dust-containing gas purification chamber 11 includes a frame 103, a purification chamber frame 203, a floating bearing assembly, a filter cloth 303, a vibrator 403 and a dust collecting bin 503; the purification chamber frame 203 has an air inlet 603 at the top, and the purification chamber frame 203 has an outlet 703 at the bottom. The purification chamber frame 203 is located on the frame 103, and the upper and lower parts of the purification chamber frame 203 are connected to the frame 103 by means of two or more floating bearing assemblies; the floating bearing assembly includes a support 803, a compression spring 903 and a bearing plate 1003, the support 803 is fixed on the frame 103, a sliding rod 1703 is fixed on the top of the support 803, the bearing plate 1003 is fixed to the side of the purification chamber frame 203, and a sliding hole is opened on the bearing plate 1003 in the vertical direction. 1003 is sleeved on the slide bar 1703 through a sliding hole and is slidably connected thereto; the compression spring 903 is sleeved on the slide bar 1703, and the upper end of the compression spring 903 contacts the bearing plate 1003, and the lower end of the compression spring 903 contacts the support 803; the filter cloth 303 is wrapped around the outside of the clean room frame 203 and fixed thereto; the vibrator 403 is fixed to the side of the clean room frame 203 and is used to make the clean room frame 203 vibrate up and down; the dust collecting bin 503 is located below the clean room frame 203 and is fixed to the frame 103, and the lower end of the clean room frame 203 is connected to the upper end of the dust collecting bin 503 by means of an annular sleeve 1803, and the annular sleeve 1803 has corrugated folds; the cyclone dust collector 10 has an exhaust port, and the pipeline from the exhaust port to the air inlet 603 is connected to the air inlet 603 by means of a corrugated hose.

[0044] The gas discharged from the cyclone dust collector 10 is transported to the inside of the dust-containing gas purification chamber 11 through a pipeline. The purification chamber frame 203 is a frame structure. The purification chamber frame 203 is located on the frame 103, and the upper and lower parts of the purification chamber frame 203 are connected to the frame 103 by means of two or more floating bearing components. The filter cloth 303 is wrapped around the outside of the purification chamber frame 203 and fixed thereto. The vibrator 403 is fixed to the side of the purification chamber frame 203 and is used to vibrate the purification chamber frame 203 up and down. The dust collecting bin 503 is located below the purification chamber frame 203 and is fixed to the frame 103. By passing the dust-containing gas from the air inlet 603 into the purification chamber frame 203, the dust-containing gas passes through the filter cloth 30 After the filter cloth 303 is formed, the dust will remain on the filter cloth 303, and the purified gas passes through the filter cloth 303. The filter cloth 303 can be shaken by the vibration of the clean room frame 203 as a whole by the vibrator 403, so as to prevent the filter cloth 303 from being blocked by the filtered dust, thereby ensuring the effectiveness of the filter cloth 303, so that the remaining dust can be processed and purified, and by covering the filter cloth 303 on the outside of the clean room frame 203 and fixing it thereto, a large amount of dust-containing gas can be processed within a certain period of time to improve the dust removal efficiency, because the contact area between the filter cloth 303 and the dust-containing gas is larger. The floating bearing assembly includes a support 803, a compression spring 903 and a bearing plate 1003. The support 803 is fixed on the frame 103. A sliding bar 1703 is fixed on the top of the support 803. The bearing plate 1003 is fixed on the side of the clean room frame 203.

The clean room frame 203 is slidably connected to the sliding bar 1703 through the bearing plate 1003. The compression spring 903 ensures that the clean room frame 203 can float up and down to cooperate with the vibrator 403 to achieve the shaking of the filter cloth 303. The filter cloth 303 and the clean room frame 203 can be fixed by a binding rope. The materials used for the annular sleeve 1803 and the filter cloth 303 are the same, and both are existing filter cloths 303. The annular sleeve 1803 and the lower end of the clean room frame 203 and the upper end of the dust collecting bin 503 can be fixed by a binding rope. By setting the annular sleeve 1803, the soft connection between the clean room frame 203 and the dust collecting bin 503 can be achieved, and the dust-containing gas can be prevented from being directly discharged from the gap between the clean room frame 203 and the dust collecting bin 503, and it is ensured that the clean room frame 203 will not be affected by the dust collecting bin 503 when vibrating up and down. The dust collecting bin 503 is used to collect dust filtered by the filter cloth 303. The top of the dust collecting bin 503 has an inlet 1103, the bottom of the dust collecting bin 503 has a dust outlet 1203, and a valve 1303 is provided at the dust outlet 1203.
