The lower bottom surface of the crushing cylinder is provided with several discharge ports at equal intervals, and the lower cylinder body of the crushing cylinder is funnel-shaped.

[0010] The combined runner consists of an upper support plate, three support blocks and a lower support plate. The circular groove is opened at the center of the upper support plate. A stepped seat is protruded at the center of the top surface of the lower support plate. The three support blocks are equidistantly distributed between the upper support plate and the lower support plate. The side ends of the support blocks are bolted with connecting plates. The side walls of the support blocks are equidistantly protruded with multiple paddles. The paddles are all fixedly connected to the support blocks at an angle, and several screening holes are opened on the paddles.

[0012] The screening mechanism consists of a vibrating screen plate and an oscillation plate.

The telescopic end of the electric push cylinder is fixedly connected to the side end of the oscillation plate.

[0013] Two fixed connecting rods are protruded from the abutting plates, and sliding limit grooves cooperating with the fixed connecting rods are opened on the vibrating screen plate. A tightening nut is threadedly connected to the fixed connecting rods.

[0014] The present invention also proposes a crushing method of a vertical shaft impact crusher with a dehydration function, comprising the following steps:

[0015] S1, first, connect the power supply to each motor, telescopic device and pump body of the device, then connect the device for conveying high-temperature airflow to the air inlet pipe, and connect the suction device to the suction pipe, then adjust the sliding block in the opening and closing control box according to demand, and control the size of the discharge opening by sliding adjustment of the sliding block, thereby controlling the discharge rate, and then control the lifting height of the lifting partition according to the crushing mode of stone hitting stone or stone hitting iron. When the lifting partition is lifted to the highest point to block the separation discharge chute, the device is in the stone hitting iron mode, and when the lifting partition slides down to unblock the separation discharge chute, the device is in the stone hitting stone mode. By setting the separation discharge chute and the lifting partition, the discharge operation of the separation chamber can be opened and closed, and the opening size of the separation discharge chute can be controlled, thereby controlling the discharge speed of the discharge layer;

[0016] S2, then add stones to the feed hopper, and start the second motor in the second motor box, so that the crushing and cleaning mechanism rotates and starts, and the combined rotor on the crushing and cleaning mechanism throws the stones entering the combined rotor at high speed, and the stones thrown out at high speed collide with the stone layer or iron layer to be crushed. Through the setting of the paddles and the screening holes, the stones that rebound and do not meet the particle size standards can be better thrown out and crushed again, thereby improving the crushing efficiency of the stones. The densely distributed screening holes on the paddles can effectively screen the crushed stones, so that stones with standard particle size can pass through the paddles more easily;

[0017] S3, then the cleaning wheel sweeps the crushed stones into the lower layer, and the discharged stones fall above the jet drying ring plate. The tilted state of the jet drying ring plate and the jet airflow will reduce the subsequent collision of the stones and allow the stones to enter the screening mechanism. The high-temperature airflow ejected from the jet holes can dehydrate and dry the tumbling stones at high temperature, thereby removing the water in the stones. During drying, the water in the equipment generates water vapor. At this time, the suction device connected to the suction pipe starts to suck the water vapor out of the device. During suction, the jet holes on the lower end surface of the jet drying ring plate work together to send the moist airflow out of the device;

[0018] S4, then the stone enters the screening mechanism for vibration screening. The reciprocating extension and contraction of the electric push cylinder drives the vibration plate to shake back and forth. The vibration plate can block the discharged stone, preventing the stone from escaping from the screening mechanism after one vibration, thereby controlling the feeding speed of the dry stone and extending the dehydration and drying time of the stone in the discharge hopper. The setting of the screening mechanism can screen out the stone with smaller particles first, preventing the smaller stones from absorbing a large amount of water and affecting the dehydration and drying of other particles of stone;

[0019] S5. Finally, the stone is dehydrated and dried in the discharge hopper. When the separation chamber is running, the rotation of the swivel ring and the transmission friction roller can better drive the lever to rotate in the separation chamber, thereby avoiding the stone from being blocked in the separation chamber. Through the setting of the anti-blocking mechanism, the discharge speed of the separated stone can be better controlled, and the stone can be prevented from being blocked in the separation chamber, thereby avoiding affecting the crushing effect of the stone inside the crushing cylinder. Finally, the fully crushed stone can be discharged, and then the power supply is disconnected. At this point, the use of the stone crushing device is completed.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: in the present invention, by coordinating the filtering and dehydrating block with the jet drying ring plate, it is convenient to remove the water in the stone, improve the efficiency of dehydration and drying, and thus realize the function of stone crushing and dehydration; by coordinating the rotation of the combined runner and the paddle, it is convenient to throw the stone at high speed for crushing, and to carry out the return material crushing, thereby improving the effect of stone crushing, and thus realizing the function of stone particle detection and re-crushing; and by coordinating the jet drying ring plate with the screening mechanism, the large and small particles of stone are separated for dehydration and drying, thereby improving the dehydration effect of the stone product, and thus realizing the function of rapid dehydration and drying of the stone from the stone powder, ultimately solving the problem that small products such as wet stone powder attached to the stone are difficult to dehydrate and dry completely.

[0040] Working Principle: In this embodiment, the present invention also proposes a crushing method of a vertical shaft impact crusher with a dehydration function, comprising the following steps:

[0041] Step one, first, power on each motor, telescopic device and pump body of the device, then connect the device for conveying high-temperature airflow to the air inlet pipe 9, and connect the suction device to the suction pipe, then adjust the sliding block 24 in the opening and closing control box 23 according to demand, and control the size of the discharge opening by sliding adjustment of the sliding block 24, thereby controlling the discharge rate, and then control the lifting height of the lifting partition 26 according to the crushing mode of stone hitting stone or stone hitting iron. When the lifting partition 26 is lifted to the highest point to block the separation discharge chute 25, the device is in the stone hitting iron mode, and when the lifting partition 26 slides down to unblock the separation discharge chute 25, the device is in the stone hitting stone mode. By setting the separation discharge chute 25 and the lifting partition 26, the discharge operation of the separation chamber 22 can be opened and closed, and the opening size of the separation discharge chute 25 can be controlled, thereby controlling the discharge speed of the discharge layer;

[0042] In step 2, stones are then added to the feed hopper 4, and the second motor in the second motor box 13 is started, so that the crushing and cleaning mechanism rotates and starts. The combined runner 11 on the crushing and cleaning mechanism throws out the stones entering the combined runner 11 at high speed. The stones thrown out at high speed collide with the stone layer or iron layer to be crushed. Through the arrangement of the paddle 30 and the screening holes 32, the rebounded stones that do not meet the particle size standards can be better thrown out and crushed again, thereby improving the crushing efficiency of the stones. The densely distributed screening holes 32 on the paddle 30 can effectively screen the crushed stones, so that stones that meet the particle size standards can more easily pass through the paddle 30.

[0043] In step three, the cleaning wheel 12 sweeps the crushed stones into the lower layer, and the discharged stones fall onto the top of the jet drying ring plate 15. The tilted state of the jet drying ring plate 15 and the jetted airflow reduce the subsequent collision of the stones and allow the stones to enter the screening mechanism. The high-temperature airflow ejected from the jet holes 20 can dehydrate and dry the tumbling stones at high temperature, thereby removing the water in the stones. During drying, the water in the equipment generates water vapor. At this time, the suction device connected to the suction pipe starts to suck the water vapor out of the device. During suction, the jet holes 20 on the lower end surface of the jet drying ring plate 15 cooperate to send the moist airflow out of the device.

[0044] Step 4: The stone then enters the screening mechanism for vibration screening. The reciprocating extension and contraction of the electric push cylinder 5 drives the vibration plate 34 to shake back and forth. The vibration plate 34 can block the discharged stone to prevent the stone from escaping from the screening mechanism after one vibration, thereby controlling the feeding speed of the dry stone and extending the dehydration and drying time of the stone in the discharge hopper 3. The setting of the screening mechanism can screen out the stone with smaller particles first, preventing the smaller stones from absorbing a large amount of water and affecting the dehydration and drying of other particles of stone.

[0045] Step five, finally the stone is dehydrated and dried in the discharge hopper 3. When the separation chamber 22 is running, the rotation of the swivel 10 and the transmission friction roller 18 can better drive the lever 16 to rotate in the separation chamber 22, thereby avoiding the stone from being blocked in the separation chamber 22. Through the setting of the anti-blocking mechanism, the discharge speed of the separated stone can be better controlled, and the stone can be prevented from being blocked in the separation chamber 22, thereby avoiding affecting the crushing effect of the stone inside the crushing drum 2. Finally, the fully crushed stone can be discharged, and then the power supply is disconnected. At this point, the use of the stone crushing device is completed.

2. The crushing method of the vertical shaft impact crusher with dehydration function according to claim 1, characterized in that: The following steps are involved: S1, firstly, power is turned on for each motor, telescopic device and pump body, then the device for conveying high-temperature airflow is connected to the air inlet pipe (9), and the suction device is connected to the suction pipe, and the sliding block (24) in the opening and closing control box (23) is adjusted. The size of the discharge opening is controlled by the sliding adjustment of the sliding block (24), thereby controlling the discharge rate. Then, the lifting height of the lifting partition (26) is controlled according to the crushing mode of stone hitting stone or stone hitting iron. When the lifting partition (26) is lifted to the highest point to block the separation discharge chute (25), it is in the stone hitting iron mode. When the lifting partition (26) slides down to release the blockage of the separation discharge chute (25), it is in the stone hitting stone mode. By setting the separation discharge chute (25) and the lifting partition (26), the discharge operation of the separation chamber (22) can be opened and closed, and the opening size of the separation discharge chute (25) can be controlled, thereby controlling the discharge speed of the discharge layer; S2, then adds stones to the feed hopper (4), and starts the second motor in the second motor box (13), so that the crushing and cleaning mechanism rotates and starts, and the combined wheel (11) on the crushing and cleaning mechanism throws out the stones entering the combined wheel (11) at high speed, and the stones thrown out at high speed collide with the stone layer or iron layer to be crushed. Through the arrangement of the paddle (30) and the screening hole (32), the stones that rebound and do not meet the particle size standard can be better thrown out and crushed again, thereby improving the crushing efficiency of the stones. The densely distributed screening holes (32) on the paddle (30) can effectively screen the crushed stones, so that the stones that meet the particle size standard can more easily pass through the paddle (30); S3, then the cleaning wheel (12) sweeps the crushed stones into the lower layer, and the discharged stones fall onto the top of the jet drying ring plate (15). The tilted state of the jet drying ring plate (15) and the jet airflow will reduce the subsequent collision of the stones and allow the stones to enter the screening mechanism. The high-temperature airflow ejected from the jet hole (20) dehydrates and dries the stones that have rolled over, thereby removing the water in the stones. At this time, the suction device connected to the suction pipe starts to suck away the water vapor. During the suction, the jet hole (20) on the lower end surface of the jet drying ring plate (15) cooperates to send out the moist airflow. S4, the stone then enters the screening mechanism for vibration screening, and the reciprocating extension and contraction of the electric push cylinder (5) drives the vibration plate (34) to reciprocate and shake. The vibration plate (34) can block the discharged stone, preventing the stone from escaping from the screening mechanism after a single vibration, thereby controlling the discharge speed of the dry stone and extending the dehydration and drying time of the stone in the discharge hopper (3). The setting of the screening mechanism can screen out the smaller stone particles first, preventing the smaller stone from absorbing a large amount of water and affecting the dehydration and drying of other stone particles; S5, finally the stone is dehydrated and dried in the discharge hopper (3). When the separation chamber (22) is running, the rotation of the rotating ring (10) and the transmission friction roller (18) can better drive the lever (16) to rotate in the separation chamber (22), thereby preventing the stone from being blocked in the separation chamber (22). By setting the anti-blocking mechanism, the discharge speed of the separated stone can be better controlled, and the stone can be prevented from being blocked in the separation chamber (22), thereby avoiding affecting the crushing effect of the stone inside the crushing cylinder (2). Finally, the fully crushed stone can be discharged, and then the power supply is disconnected, and the use of the stone crusher is terminated.
