Description

[0002] At present, with the rapid development of the construction industry, the demand for machine-made sand continues to climb. As one of the core equipment for machine-made sand production, the operating conditions of the roller press have a crucial impact on production efficiency, the environment, and resource utilization. The roller press crushes and extrudes various materials under strong pressure to convert them into standard sand particles.

[0003] In the process of materials entering the roller press, when the materials are poured from the hopper and the gravel initially processed by the crushing roller is crushed, sand particles will fly during the crushing process. These flying sand particles fill the entire construction environment, resulting in dust flying at the construction site, reducing the quality of the construction environment. On the one hand, it affects the physical health of the staff, and on the other hand, it interferes with the operation of the machinery, thereby reducing the sand output efficiency in terms of machinery operation.

[0004] At the same time, the collection of these flying sand particles after construction is inefficient.

Detailed implementation manners

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0023] As Figures 1 to 11 shown, a sand making device with a high sand discharge rate according to the present invention includes a sand making mechanism, a separation mechanism, a dust reduction mechanism and a collection mechanism.

[0024] The sand making mechanism includes a loading hopper 1, a crushing roller 2 arranged inside the loading hopper 1, and a driving motor 13 for driving the crushing roller 2. Among them, there are two crushing rollers 2, both of which are rotatably installed inside the loading hopper 1. At the axial ends of the two crushing rollers 2, there are two meshing gears. By rotating one of the crushing rollers 2, the synchronous rotation of the two crushing rollers 2 can be controlled. The driving motor 13 is fixedly connected to the frame of the loading hopper 1, and the rotation of the crushing roller 2 is controlled through the cooperation of a belt and a pulley.

[0025] During sand making, the preliminarily processed sand and gravel are put into the inner cavity of the loading hopper 1, and then the driving motor 13 is started to control the rotation of the crushing roller 2 to realize the dry sand making operation. A discharge port is arranged at the bottom of the loading hopper 1, and a discharge chute is inclined at the discharge port to facilitate the collection of the processed materials.

[0026] The separation mechanism includes a wind guide cylinder 3, a guide vane 20, and a guide vane motor 19. The wind guide cylinder 3 is arranged at the upper opening of the loading hopper 1, and the outer wall of the wind guide cylinder 3 is fixedly connected to the outer wall of the loading hopper 1.

[0027] The guide vane motor 19 controls the rotation of the guide vane 20 to form an air flow in the inner cavity of the wind guide cylinder 3. The outer wall of the guide vane motor 19 is fixedly connected to the inner wall of the wind guide cylinder 3, and the outer wall of the guide vane 20 is fixedly connected to the output shaft of the guide vane motor 19. By controlling the rotation of the guide vane 20 through the guide vane motor 19, a negative pressure is generated inside the wind guide cylinder 3, sucking the sand grains at the upper opening of the loading hopper 1 into the inner cavity of the wind guide cylinder 3 and discharging them from the other end. Thus, the sand grains are separated. The dust reduction mechanism includes an atomizing nozzle 4 and a separation cover 5. The atomizing nozzle 4 is arranged inside the wind guide cylinder 3, and the output end of the atomizing nozzle 4 extends into the inner part of the wind guide cylinder 3 and is uniformly arranged in a ring shape with multiple ones. By spraying atomized water droplets through the atomizing nozzle 4, the air flow in the wind guide cylinder 3 is dust-reduced.

[0028] The separation cover 5 is fixed at the end of the wind guide cylinder 3 where the air is exhausted, and there is an opening at the bottom, so that the water mist and sand grains are synchronously discharged from the bottom of the separation cover 5 to prevent the sand grains from flying and optimize the construction environment.

[0029] The collection mechanism includes a collection hopper 33, a separation layer 16, and a drainage hopper 35. The bottom surface of the collection hopper 33 is connected to the heat dissipation rib plate of the driving motor 13. Among them, the collection hopper 33 is made of aluminum material with excellent heat conduction effect, and the separation layer 16 is made of sponge material with a non-woven fabric for filtration on the surface.

[0030] The separation layer 16 is obliquely arranged in the collection hopper 33 and is directly below the bottom opening of the separation cover 5. The drainage hopper 35 is fixedly installed on the bottom surface of the collection hopper 33. Among them, the water droplets containing sand grains dripping from the separation cover 5 fall on the surface of the separation layer 16. The separation layer 16 filters the sand grains, and the sand grains gather on the upper surface of the separation layer 16. The water droplets seep downward and flow into the collection hopper 33 for recycling. At the same time, the wet separation layer 16 absorbs the heat generated when the drive motor 13 works, improving the heat dissipation efficiency of the drive motor 13 on the one hand, and on the other hand, improving the drying efficiency of the sand grains above the separation layer 16.

[0031] A transfer box 18 is fixedly installed on the inner wall of the separation cover 5. There is a cavity inside the transfer box 18. The side of the transfer box 18 facing the exhaust direction of the air guide cylinder 3 is obliquely arranged. When the air guide cylinder 3 exhausts, the water droplets containing sand grains collide with the inclined surface of the transfer box 18, thereby guiding the water droplets to flow downward.

[0032] The transfer box 18 has a liquid inlet end and a liquid discharge end, and the liquid discharge end of the transfer box 18 is connected to the atomizing nozzle 4. The liquid inlet end of the transfer box 18 is connected to an external water pump. The external cold water enters the inner cavity of the transfer box 18 to cool the transfer box 18, and then is discharged by the atomizing nozzle 4. The inclined outer wall of the cooled transfer box 18 helps the condensation of water vapor and improves the flowing efficiency of the water droplets containing sand grains.

[0033] As a preferred embodiment of the present invention, an installation beam 7 is slidably installed on the inner wall of the collection hopper 33, an installation block 22 is slidably installed on the inner wall of the installation beam 7, and the outer wall of the installation block 22 is slidably fitted with the inner wall of the installation beam 7.

[0034] An installation frame 21 is fixedly installed on the bottom surface of the installation block 22. The installation frame 21 is a common U-shaped frame. A scraping plate 8 for scraping the separation layer 16 is rotatably installed at the bottom of the installation frame 21 through a torsion spring. The installation beam 7 slidably installed along the inner wall of the collection hopper 33 drives the scraping plate 8 to slide through the installation block 22, thereby scraping and combing the sand grains on the inclined surface of the separation layer 16 and flattening the sand grains.

[0035] A locking plate 23 is fixedly installed on the side wall of the installation frame 21 to limit the rotation direction of the scraping plate 8 by setting the locking plate 23.

[0036] A control motor 9 is fixedly installed on the side wall of the collection hopper 33. A transmission shaft 25 is fixedly installed on the output shaft of the control motor 9. The control motor 9 is used to control the rotation of the transmission shaft 25.

[0037] A transmission screw 12 is rotatably installed on the side wall of the collection hopper 33. A sliding block 10 is connected to the outer wall of the transmission screw 12 through thread fit. Rotating the transmission screw 12 drives the sliding block 10 to slide along the axis of the transmission screw 12.

[0038] The outer wall of the sliding block 10 is in sliding fit with the side wall of the collecting hopper 33, thereby improving the stability of the sliding of the sliding block 10. The side wall of the sliding block 10 is fixedly connected to one side of the mounting beam 7. Thus, during the rotation of the driving screw 12, the sliding block 10 is driven to slide, and further the mounting beam 7 and the scraping plate 8 are controlled to slide, scraping the sand grains on the outer wall of the scraping and separating layer 16.

[0039] The transmission shaft 25 is connected to the driving screw 12 through a universal coupling. Since the outer wall of the separating layer 16 is inclined, the movement trajectory of the scraping plate 8 is parallel to the separating layer 16, which causes the driving screw 12 to be inclined. At the same time, the transmission shaft 25 is horizontally arranged, so a universal coupling is used for connection to achieve transmission.

[0040] An elastic net 34 is fixedly installed on the inner wall of the collecting hopper 33. The elastic net 34 is located on the inner wall of the separating layer 16, and both the elastic net 34 and the separating layer 16 are made of elastic materials. Among them, the elastic net 34 is a metal net, which provides support for the separating layer 16 when the separating layer 16 collects sand grains.

[0041] A connecting cover 38 is fixedly installed on the bottom surface of the elastic net 34. An exhaust notch is provided on the outer wall of the connecting cover 38, and an air inlet is arranged on one side of the connecting cover 38. Gas is injected through the air inlet of the connecting cover 38, and the gas is discharged through the exhaust notch. At this time, air is blown from one side of the elastic net 34 towards the upper part of the separating layer 16 to prevent sand grains from blocking the separating layer 16 and maintain the filtering efficiency of the separating layer 16.

[0042] An elastic plate 36 is fixedly installed in the exhaust notch. The elastic plate 36 is inclined. By setting the inclined elastic plate 36, the air flow can be guided to discharge, thereby backwashing the separating layer 16. At the same time, when the air flow passes through, the elastic plate 36 vibrates, driving the elastic net 34 to vibrate, and cooperating with the backwashing of the separating layer 16, thereby improving the dredging quality of the separating layer 16.

[0043] An air delivery pipe 29 is fixedly installed on the outer wall of the collecting hopper 33. One end of the air delivery pipe 29 extends into the inner cavity of the separating layer 16 and is fixedly connected to one end of the connecting cover 38. The air delivery pipe 29 is used to inject gas into the inner cavity of the connecting cover 38.

[0044] A cylindrical cavity is arranged on one side of the connecting cover 38, and a vibrating ball 37 is arranged in the cylindrical cavity. When the air flow enters the connecting cover 38, it drives the vibrating ball 37 to vibrate. The vibration of the vibrating ball 37 inside the connecting cover 38 continuously changes the flow state of the air flow, thereby changing the vibration amplitude of the elastic net 34, which is used to assist the backwashing and cleaning of the separating layer 16.

[0045] As a preferred embodiment of the present invention, a plurality of mounting blocks 22 are uniformly arranged along the inner wall of the mounting beam 7. An elastic member is arranged between two adjacent mounting blocks 22, and the two mounting blocks 22 are elastically connected, so that the two mounting blocks 22 have a tendency to move away from each other.

[0046] The outer wall of the mounting block 22 is provided with an X-shaped telescopic frame 24. Two adjacent mounting blocks 22 are connected by the X-shaped telescopic frame 24, so as to synchronously control the sliding of multiple mounting blocks 22 by controlling the deflection of the X-shaped telescopic frame 24. An arc-shaped block 14 for pressing the X-shaped telescopic frame 24 is fixedly installed on the inner wall of the collection hopper 33. When the mounting beam 7 slides along the inner wall of the collection hopper 33, the X-shaped telescopic frame 24 is pressed by the arc-shaped block 14, so as to control the synchronous sliding of multiple mounting blocks 22. Furthermore, when the mounting beam 7 slides, multiple arc-shaped movement tracks are formed on the inclined outer wall of the separation layer 16.

[0047] An air storage cylinder 32 is fixedly installed on the bottom surface of the collection hopper 33. The air storage cylinder 32 is used for storing air. An air inlet pipe 17 with one-way conduction is fixedly installed on the outer wall of the air storage cylinder 32. A one-way valve is arranged inside the air inlet pipe 17 for controlling the injection of air into the air storage cylinder 32 through the air inlet pipe 17.

[0048] A control plug 39 is elastically installed on the inner wall of the air storage cylinder 32. A spring is fixedly installed on the outer wall of the control plug 39, and the other end of the spring is fixed to the inner cavity of the air storage cylinder 32.

[0049] A connection block 30 for connecting with the air delivery pipe 29 is fixedly installed on the outer wall of the air storage cylinder 32. When the spring pushes the control plug 39 to slide, the air inside the air storage cylinder 32 is injected into the inner cavity of the air delivery pipe 29 through the connection block 30 and discharged from the outer wall of the connection cover 38.

[0050] A floating seal plug 41 is slidably installed on the inner wall of the connection block 30. The outer wall of the floating seal plug 41 is hermetically fitted with the inner wall of the connection block 30. A tapered plug 40 is fixedly installed on the bottom surface of the floating seal plug 41, and sliding the floating seal plug 41 drives the tapered plug 40 to slide synchronously.

[0051] A tapered hole adapted to the tapered plug 40 is formed in the inner cavity of the connection block 30. The connection block 30 is blocked by inserting the tapered plug 40 into the tapered hole. When it is necessary to inject air into the air delivery pipe 29, the floating seal plug 41 is pressed to drive the tapered plug 40 to slide down until it is separated from the inner wall of the tapered hole. At this time, the inner cavity of the connection block 30 is conducted, so as to facilitate the injection of air from the air storage cylinder 32 into the air delivery pipe 29.

[0052] As a preferred embodiment of the present invention, a mounting plate 15 is fixedly installed on the inner wall of the connection block 30. The bottom surface of the mounting plate 15 is elastically connected to the upper end surface of the floating seal plug 41. Among them, a spring is fixedly installed on the bottom surface of the mounting plate 15, and the other end of the spring is connected to the floating seal plug 41.

[0053] To facilitate the control of the sliding of the floating sealing plug 41 and the tapered plug 40, a guide rod 31 is slidably installed on the inner wall of the mounting plate 15. One end of the guide rod 31 is fixedly connected to the outer wall of the floating sealing plug 41. By pressing the guide rod 31, the floating sealing plug 41 and the tapered plug 40 are pushed to slide, so that the tapered plug 40 is separated from the tapered hole. After releasing the guide rod 31, the floating sealing plug 41 and the tapered plug 40 are reset by elastic force, thereby closing the inner cavity of the adapter block 30.

[0054] A top pressing plate 6 for pressing the guide rod 31 is fixedly installed at one end of the mounting beam 7 away from the sliding block 10. During the sliding of the mounting beam 7, the top pressing plate 6 slides synchronously. When the mounting beam 7 slides, the top pressing plate 6 slides synchronously, thereby controlling the top pressing plate 6 to press the guide rod 31. When the top pressing plate 6 is in contact with the outer wall of the guide rod 31, the inner cavity of the adapter block 30 remains in a conducting state. After the top pressing plate 6 and the guide rod 31 are separated, the inner cavity of the adapter block 30 is closed.

[0055] A transmission crankshaft 26 is fixedly installed on the outer wall of the transmission shaft 25. During the rotation of the transmission shaft 25, the transmission crankshaft 26 rotates synchronously.

[0056] A transmission connecting rod 27 is rotatably installed at the journal part of the transmission crankshaft 26. The other end of the transmission connecting rod 27 is rotatably installed with an adjusting plug 28. A control cylinder 11 is fixedly installed on the bottom surface of the collecting hopper 33. The inner wall of the control cylinder 11 is slidably fitted with the outer wall of the adjusting plug 28. During the rotation of the transmission crankshaft 26, the adjusting plug 28 is controlled to reciprocate in the inner cavity of the control cylinder 11.

[0057] A one-way conducting air inlet is provided at the bottom of the control cylinder 11. One end of the air inlet pipe 17 away from the air storage cylinder 32 communicates with the inner cavity of the control cylinder 11. A one-way valve is provided inside the air inlet. During the reciprocating sliding of the adjusting plug 28, the control cylinder 11 sucks external air and injects it into the inner cavity of the air storage cylinder 32. At this time, the control plug 39 slides to compress the spring.

[0058] When the top pressing plate 6 slides to be in contact with the outer wall of the guide rod 31, the inner cavity of the adapter block 30 is in a conducting state. At this time, the control plug 39 slides, and the air inside the air storage cylinder 32 is injected into the inner cavity of the air delivery pipe 29 through the adapter block 30, thereby realizing the backwashing of the separation layer 16.
