[0002] The process of bulk materials being divided into different particle sizes through one or more layers of screens is called screening. Screening machines use the relative movement between bulk materials and the screen surface to allow some particles to pass through the screen holes, and classify materials such as sand, gravel, and crushed stone into different grades according to particle size.

[0003] The existing sand processing generally uses a drum-type sand screening machine for screening, which is fully dispersed and separated by repeated tumbling and sliding to achieve the purpose of screening. However, after the screening work is completed, some sand still adheres to the screen drum. When cleaning, people often remove it from the sand screening machine first, and then install it back into the sand screening machine after the cleaning is completed. This method of cleaning the screen drum is too complicated to operate. Therefore, the utility model proposes an environmentally friendly sand processing equipment with good screening effect to solve the above problems. Utility Model Content

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0021] according to Figure 1-5 As shown, this embodiment proposes an environmentally friendly sand processing equipment with good screening effect, including a box body 1, a screen cylinder 2 and a discharge pipe 3. The screen cylinder 2 is rotatably installed inside the box body 1, and a discharge pipe 3 is provided at the lower right side of the box body 1. A conveyor belt 4 is provided at the lower part of the box body 1. The box body 1 is provided with a driving mechanism matching the screen cylinder 2, and the top of the box body 1 is provided with a cleaning mechanism. Sand particles are put into the screen cylinder 2, and the screen cylinder 2 is driven by the driving mechanism to rotate. The sand particles are screened by the screen cylinder 2, and qualified sand particles pass through the mesh holes of the screen cylinder 2 and fall onto the conveyor belt 4, and then the conveyor belt 4 drives the sand particles to move to the discharge pipe 3 and discharge outward. After the sand particles are screened, the sand particles adhering to the screen cylinder 2 can be automatically removed by the cleaning mechanism, thereby solving the problem of complicated operation of cleaning the screen cylinder by disassembly and assembly in the prior art.

[0022] The driving mechanism includes a transmission gear 5, a No. 1 motor 6 and a driving gear 7. The transmission gear 5 is installed on the left side of the screen cylinder 2. The No. 1 motor 6 is installed on the left side of the inside of the box body 1. The output end of the No. 1 motor 6 is installed with a driving gear 7. The outer wall of the driving gear 7 is meshed with the outer wall of the transmission gear 5. The right side of the box body 1 is provided with an auxiliary wheel 11 matching the screen cylinder 2. The No. 1 motor 6 drives the driving gear 7 to rotate. Because the outer wall of the driving gear 7 is meshed with the outer wall of the transmission gear 5, the driving gear 7 can drive the transmission gear 5 to rotate. Because the transmission gear 5 is connected to the screen cylinder 2, the driving gear 7 can drive the screen cylinder 2 to rotate through the transmission gear 5, so that centrifugal force is generated inside the screen cylinder 2. Sand particles of qualified size pass through the mesh holes inside the screen cylinder 2 with the help of the centrifugal force of the screen cylinder 2 and automatically fall onto the conveyor belt 4, while sand particles of unqualified size continue to exist inside the screen cylinder 2.

[0023] An end cover 12 is provided on the right side of the screen cylinder 2. The shape of the end cover 12 is set to a "convex" shape structure. A locking groove is provided at the bottom of the end cover 12. A locking edge 20 is locked inside the end cover 12. The end cover 12 is locked and connected to the opening of the screen cylinder 2 through the locking edge 20. Before the cleaning mechanism works, the end cover 12 is covered on the right side of the screen cylinder 2. The end cover 12 is locked at the opening of the screen cylinder 2 through the locking edge 20 and closes it. Because the cleaning mechanism cleans sand particles through the pneumatic principle, it is also easy to cause sand particles to float into the air, further enhancing the environmental protection function of the equipment.

[0024] The cleaning mechanism includes an air pump 13, an aeration pipe 14, a vent pipe 15 and a nozzle 16. The air pump 13 is installed on the top of the box body 1. The aeration pipe 14 is provided on the upper part of the box body 1. The output end of the air pump 13 is connected to one end of the aeration pipe 14 through the vent pipe 15. The bottom of the aeration pipe 14 is provided with a nozzle 16. The aeration pipe 14 and the screen cylinder 2 are both provided with an inclination angle inside the box body 1. The aeration pipe 14 and the screen cylinder 2 are parallel in position up and down. There are multiple nozzles 16, and the distances between adjacent nozzles 16 are equal. The air pump 13 inputs external air into the aeration pipe 14 through the ventilation pipe 15, and the aeration pipe 14 sprays air toward the screen cylinder 2 through the nozzle 16. Due to the type of nozzle 16, the air pressure can be increased, and the sand and gravel adhered to the surface of the screen cylinder 2 can be blown to move. Since the screen cylinder 2 is rotating, the nozzle 16 can spray to each side of the outside of the screen cylinder 2, so that it falls onto the conveyor belt 4 and is also discharged outward through the discharge pipe 3.

[0025] A feeding mechanism is provided inside the screen cylinder 2, and a No. 2 motor 8 is also provided on the left side inside the box body 1. The output end of the No. 2 motor 8 is connected to the feeding mechanism. Unqualified sand and gravel inside the screen cylinder 2 can be transported outward through the feeding mechanism, so that it is automatically moved out of the box body 1, and cooperates with the cleaning mechanism to automatically clean the sand and gravel inside the box body 1, eliminating the manual cleaning step.

[0026] The feeding mechanism includes a rotating shaft 9 and a blade 10. The rotating shaft 9 is rotatably installed inside the screen cylinder 2, and the blade 10 is fixed on the outside of the rotating shaft 9. The spiral direction of the blade 10 is set from left to right. The left end of the rotating shaft 9 passes through the interior of the transmission gear 5 and is connected to the output end of the No. 2 motor 8. The outer side of the rotating shaft 9 is rotatably connected to the inner wall of the transmission gear 5 through a bearing 17. The No. 2 motor 8 drives the blade 10 to rotate inside the screen cylinder 2 through the rotating shaft 9. Since the rotating shaft 9 and the transmission gear 5 are rotatably connected through the bearing 17, the transmission gear 5 will not be interfered with when the rotating shaft 9 rotates. Since the spiral direction of the blade 10 is from left to right, it can drive the unqualified sand particles inside the screen cylinder 2 to move from the inside to the outside, and at the same time, the sand particles blown into the screen cylinder 2 by the cleaning mechanism are also discharged to the outside of the box body 1.

[0027] A soft cloth tube 18 is provided at the right end of the discharge pipe 3, and a clamp 19 is provided at the top of the soft cloth tube 18. An arc groove matching the discharge pipe 3 is provided inside the clamp 19, and the two ends at the top of the clamp 19 are detachably connected by bolts. The clamp 19 is first put on the top of the soft cloth tube 18, and then the clamp 19 and the soft cloth tube 18 are put together on one end of the discharge pipe 3, and the bolts on the top of the clamp 19 are turned to drive the two side ends of the top of the clamp 19 to close to each other, and then the clamp 19 is used to clamp the top of the soft cloth tube 18, so that the soft cloth tube 18 is fixed to one end of the discharge pipe 3, and the soft cloth tube 18 is used to prevent the sand from scattering outward when discharging, so as to protect people's working environment.

[0028] The environmentally friendly sand processing equipment with good screening effect is provided with a cleaning mechanism on the top of the box body 1, and the cleaning mechanism is composed of an air pump 13, an aeration pipe 14, a vent pipe 15 and a nozzle 16. The air pump 13 inputs the outside air into the aeration pipe 14 through the vent pipe 15, and the aeration pipe 14 sprays the air to the screen cylinder 2 through the nozzle 16. Due to the type of the nozzle 16, the air pressure can be increased, and the sand and gravel adhered to the surface of the screen cylinder 2 can be blown to move. Since the screen cylinder 2 is rotating, the nozzle 16 can spray to each side of the outer side of the screen cylinder 2, so that The sand particles fall onto the conveyor belt 4 and are discharged outward through the discharge pipe 3, so as to automatically clean the sand particles adhering to the screen cylinder 2; and a feeding mechanism is arranged inside the screen cylinder 2, and the feeding mechanism is composed of a rotating shaft 9 and blades 10. The No. 2 motor 8 drives the blades 10 to rotate inside the screen cylinder 2 through the rotating shaft 9. Since the spiral direction of the blades 10 is from left to right, the unqualified sand particles inside the screen cylinder 2 can be driven to move from the inside to the outside, and the sand particles blown into the screen cylinder 2 by the cleaning mechanism are also discharged to the outside of the box body 1.
