[0026] 2. Compared with the prior art, in the present invention, the ore is conveyed into the feed pipe through a screw conveyor, and after the grinding disc drives the ore to rotate and is squeezed with the grinding roller, the grinding roller crushes the ore into powder; in addition, the hot air and ore powder entering the filter box will be filtered by the filter bag, stay on the outside of the filter bag, and fall on the guide plate. Guided by the guide plate, the ore powder will fall into the discharge hopper, and the filtered hot air is conveyed to the wind box through the third pipeline.

[0027] 3. Compared with the prior art, in the present invention, when the motor drives the rotating plate and the blocking plate to rotate, when the blocking plate blocks one end of the third pipe, the hot air cannot be discharged through the third pipe, so that the hot air will enter the vertical pipe in one direction through the fourth pipe and the cooperation of the second one-way valve; as the motor drives the rotating plate to rotate, when the blocking plate no longer blocks one end of the third pipe, the hot air will be discharged into the hot air box, and the filtered hot air will also intermittently and continuously enter the vertical pipe through the intermittent blocking of the third pipe by the blocking plate. The hot air entering the vertical pipe will squeeze the piston block, and when the resistance roller resists the inclined seat, the inclined seat will push the slide plate and the rack to slide, the rack drives the rotating gear to rotate, and the rotating shaft drives the filter bag to rotate, and at the same time squeezes through the ribs. In addition, when the rack slides, it will also pass through the resistance wheel pair The inclined block squeezes and lifts the guide plate a certain distance; when the piston block moves to the bottom position of the riser, the laser ranging sensor detects the distance between the lifting frame and the fixed box at this time, so that the control module will open the solenoid valve to allow the gas in the riser to be discharged through the solenoid valve. Without the compression of the air, the lifting frame drives the piston rod to move upward and reset to the initial position under the elastic force of the fourth spring. When the elastic force of the third spring is released, the rack drives the slide plate to slide back and reset, so that the rotating rod no longer twists the filter bag and can be quickly released, thereby further cleaning the filter bag. In addition, at the moment the filter bag rotates, the knocking plate will also hit the outside of the vibration spring, causing the filter bag to vibrate, allowing the ore powder on the filter bag to fall on the guide plate, thereby improving the cleaning efficiency of the filter bag.

With the cooperation of valve 208, it enters the vertical pipe 2011 in one direction; as the motor 2013 drives the rotating plate 2014 to rotate, when the blocking plate 2015 no longer blocks one end of the third pipe 206, the hot air will be discharged into the hot air box 205, and a part of the hot air will be discharged to the outside through the fifth pipe 209, and the other part of the hot air will be transported to the hot air pipe 103 through the second pipe 202 for recycling. Since the height of the second pipe 202 is higher than the fifth pipe 209, the hot air with high temperature will float upward, so that the hot air with high temperature will enter the second pipe 202, and the hot air with low temperature will be discharged through the fifth pipe 209.

[0079] In the above process, the filtering hot air will intermittently and continuously enter the vertical pipe 2011 through the intermittent blocking of the third pipe 206 by the blocking plate 2015.

[0080] In order to increase the cleaning effect of the filter bag 40, in this embodiment, the bottom of the guide plate 50 is fixedly connected with an inclined block 503, the top of the rack 603 is fixedly connected with a resistance wheel 605, the filter box 20 is fixedly connected with a support plate 606, and multiple groups of second springs 607 are fixedly connected to the support plate 606. The bottom of the guide plate 50 is fixedly connected to the connecting block 502, and the connecting block 502 is fixedly connected to the second spring 607. When the resistance wheel 605 resists the inclined block 503, the guide plate 50 will be lifted. When the resistance wheel 605 no longer resists the inclined block 503, the elastic force of the second spring 607 will push the guide plate 50 to move downward, thereby generating vibration and accelerating the falling of ore powder on the guide plate 50. In addition, multiple groups of cross plates 405 are fixedly connected in the filter box 20, and the outside of the cross plates 405 corresponding to the outside of the filter bag 40 is fixedly connected with a vibration spring 406, and the outside of the filter bag 40 is fixedly connected with a knocking plate 407.

[0081] In order for those skilled in the art to fully understand the technical solution, the method of using this embodiment is as follows:

[0082] The ore is conveyed into the feed pipe 1015 through the screw conveyor, and the driving machine 1010 is started to drive the gear box 1016 to work, and the gear box 1016 drives the rotating disk 1019 to rotate, and the rotating disk 1019 drives the grinding disk 1020 to rotate, and the grinding disk 1020 drives the ore to rotate and squeeze with the grinding roller 1018, and the grinding roller 1018 grinds the ore into powder;

[0083] Subsequently, the hot air blower 102 is started to work, and the hot air blower 102 conveys the hot air into the grinding shell 10 through the hot air pipe 103. The powdered ore particles move upwards under the blowing of the hot air, and are conveyed into the filter box 20 through the first pipe 201. In addition, the motor drives the rotating rod 1012 to rotate, and the rotating rod 1012 drives the rotating seat 1013 and the powder selection blade 1014 to rotate. The ore particles that do not meet the diameter size can be knocked down to the grinding disc 1020 for further grinding under the rotation of the powder selection blade 1014 as the hot air blows.

[0084] The hot air and ore powder entering the filter box 20 will stay outside the filter bag 40 after being filtered by the filter bag 40, and will also fall on the guide plate 50. The ore powder will fall into the discharge hopper 2018 under the guidance of the guide plate 50, and the filtered hot air will be transported to the wind box 205 through the third pipe 206;

[0085] At the same time, the motor 2013 drives the rotating plate 2014 and the blocking plate 2015 to rotate. When the blocking plate 2015 blocks one end of the third pipe 206, the hot air cannot be discharged through the third pipe 206, so that the hot air will enter the vertical pipe 2011 in one direction through the fourth pipe 207 and the cooperation of the second one-way valve 208; as the motor 2013 drives the rotating plate 2014 to rotate, when the blocking plate 2015 no longer blocks one end of the third pipe 206, the hot air will be discharged into the hot air box 205, a part of the hot air is discharged to the outside through the fifth pipe 209, and another part of the hot air is transported to the hot air pipe 103 through the second pipe 202 for recycling;

[0086] In this way, through the intermittent blocking of the third pipe 206 by the blocking plate 2015, the filtered hot air will also intermittently and continuously enter the vertical pipe 2011, and the hot air entering the vertical pipe 2011 will squeeze the piston block 706, and the piston block 706 will press the piston rod 705 and the lifting frame 70 frame 101, so that the lifting frame 70 drives the contact roller 702 to move downward, and at the same time, the lifting frame 70 compresses the fourth spring 707, and when the contact roller 702 contacts the inclined seat 609, the inclined seat 609 will push the slide plate 604 and the rack 603 to slide, and the rack 603 drives the rotating gear 404 to rotate, and the rotating gear 404 drives the rotating shaft 403 to rotate, and the rotating shaft 403 drives the filter bag 40 to rotate, and at the same time squeezes through the rib 402, and in addition, when the rack 603 slides, it will also squeeze the inclined block 503 through the contact wheel 605, and the inclined block 503 squeezes the guide plate 50 and lifts it a certain distance;

[0087] When the piston block 706 moves to the bottom of the riser 2011, the laser distance sensor 701 detects the distance A between the lifting frame 70 and the fixed box 2010 at this time, so that the control module 80 will open the solenoid valve 2012 to allow the gas in the riser 2011 to be discharged through the solenoid valve 2012. Without the compression of the air, under the elastic force of the fourth spring 707, the lifting frame 70 drives the piston rod 705 to move upward and reset to the initial position. After the laser distance sensor 701 detects the initial distance B (the distance between the lifting frame 70 and the top of the fixed box 2010), the control module 80 closes the solenoid valve 2012 again.

[0088] In addition, when the elastic force of the third spring 608 is released, the rack 603 drives the slide plate 604 to slide back and reset, so that the rotating rod 1012 no longer twists the filter bag 40 and is quickly released. At the same time, at the moment of rotation, the knocking plate 407 also hits the outside of the vibration spring 406, causing vibration of the filter bag 40, so that the ore powder on the filter bag 40 falls on the guide plate 50. By twisting the filter bag 40, the ore powder outside the filter bag 40 also falls on the guide plate 50.

[0089] The release of the inclined block 503 by the abutment wheel 605 will also accelerate the ore powder on the guide plate 50 to fall into the discharge hopper 2018.

[0090] Embodiment 2

[0091] This embodiment is different from the second embodiment in that, in this embodiment, an air bag 30 is fixedly connected to the outside of the filter box 20, a plurality of pulse valves 301 are fixedly connected to the outside of the air bag 30, an output end of the pulse valve 301 is fixedly connected to an air pipe 302, one end of the air pipe 302 extends into the filter box 20, and a blowing pipe 303 is fixedly connected to the bottom of the air pipe 302 corresponding to the position of the filter bag 40.

[0092] The present embodiment is explained as follows: the gas can also be intermittently sprayed through the pulse valve 301 and sprayed into the filter bag 40 through the blowing pipe 303, so as to realize the vibration of the filter bag 40 and allow the ore powder outside the filter bag 40 to fall off. The first embodiment can be combined with the second embodiment. When the filter bag 40 is twisted, the control module 80 controls the pulse valve 301 to work, so as to allow high-speed pulse gas to enter the twisted filter bag 40, thereby further increasing the contact area between the air and the filter bag 40 and achieving sufficient cleaning.
