Description

Technical Field

[0001] The utility model relates to the technical field of sorting equipment, in particular to an anti-blocking and easy-to-clean drum screen. Background Art

[0002] The drum screen is a commonly used sorting equipment that screens materials by the aperture of the screen holes. Qualified materials are discharged from the bottom of the screen drum, and unqualified materials are transported to the discharge slope as the drum screen rolls and discharged. It is mostly used to separate gravel from sand and gravel soil.

[0003] When the existing drum screen is working, if the water content of the gravel is high, the screen is prone to clogging, affecting normal operation. Similarly, qualified sand will adhere to the surface of the large-particle gravel and be discharged together with the waste, requiring repeated screening, resulting in low screening efficiency.

[0004] The existing drum screen is only cleaned by setting a brush. Due to the strong adhesion of wet materials, it is difficult to be swept away by the brush. Workers need to use a high-pressure water gun to clean it after the machine is shut down, which makes cleaning inconvenient. Therefore, a non-blocking and easy-to-clean drum screen is proposed. Utility Model Content

[0005] The utility model aims to solve the problems in the prior art of easy clogging, low screening efficiency and inconvenient cleaning of drum screens when screening wet materials, and proposes an anti-clogging and easy-to-clean drum screen.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A blockage-proof and easy-to-clean drum screen comprises a frame and a hopper, the frame comprising a first mounting frame and a second mounting frame with a slide groove, a driving assembly is slidably provided in the first mounting frame, a mounting seat is slidably provided in the second mounting frame, first sliders are provided at both ends of the mounting seat, a first spring group is fixedly connected to the bottom of the mounting seat, a screen drum is provided between the driving assembly and the mounting seat, a rotating assembly is provided in the screen drum, a vibration assembly is provided in the rotating assembly, a discharge slope is provided at the output end of the frame corresponding to the screen drum, a wire roller is provided at the drum wall of the frame corresponding to the screen drum, and the hopper is located at the input end of the screen drum.

[0008] Preferably, the drive assembly includes a sliding housing and a planetary gear set, a second slider is fixedly connected to both sides of the sliding housing, a second spring group is fixedly connected to the top and bottom ends of the sliding housing, and the second spring group is fixedly connected to the top and bottom ends inside the first mounting frame.

[0009] Preferably, the planetary gear set is fixedly installed inside the sliding housing, and the planetary gear set includes a sun gear and planetary gears. One side of the sun gear passes through the sliding housing and is rotatably connected to the motor, the other side of the sun gear is connected to the vibration component, and one side of the planetary gear is fixedly connected to the turntable.

[0010] Preferably, a through hole is opened in the center of the turntable, and the outer wall of the turntable passes through the sliding housing and is fixedly connected to a rotating sleeve.

[0011] Preferably, the rotating assembly includes a sleeve, a support ring and a connecting ring, the support ring is located at one end and the middle section of the sleeve, the connecting ring is located at the other end of the sleeve, the outer walls of the support ring and the connecting ring are fixedly connected with a number of pillars, and the pillars are welded to the inner wall of the screen cylinder.

[0012] Preferably, a rotating rod is fixedly connected to a side of the connecting ring facing the frame, and the rotating rod is rotatably connected to the mounting seat.

[0013] Preferably, the vibration assembly includes a vibration rod, one end of the vibration rod passes through the support ring and the rotating sleeve to be fixedly connected to the sun gear, and the other end of the vibration rod passes through the support ring to be rotatably connected to the connecting ring.

[0014] Preferably, an eccentric block is fixedly connected to the vibration rod corresponding to the sleeve, and the size of the eccentric block is smaller than the inner diameter of the sleeve.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model can drive the vibration component to work while driving the screen drum to rotate by setting a driving component. The planetary gears are driven to rotate by the motor, and the vibration rod is driven to rotate at high speed by the sun gear. When the vibration rod rotates at high speed, the eccentric block is driven to rotate at high speed. The rotation of the eccentric block generates an unbalanced centrifugal force, which makes the screen drum vibrate. At the same time, the sun gear drives the planetary gears to rotate at a low speed, and the planetary gears drive the turntable and the rotating sleeve to rotate. The rotating sleeve drives the rotating component and the screen drum to rotate at a low speed, thereby achieving the effect of self-vibration.

[0017] 2. Under the joint action of the vibration component and the wire roller, the utility model can effectively clean the wet materials attached to the wall of the screen drum and separate the sand and gravel attached together. After the attached sand and gravel enter the screen drum, the sand is separated from the gravel by the vibration of the vibration component and the rotation of the screen drum during the sliding process. When a large area of ​​wet sand is attached to the screen, the wet sand is fallen off by the vibration of the vibration component. When the remaining small amount of attachments rotates with the screen drum to the wire roller, it is swept away by the wire roller under the action of friction, thereby improving the cleaning efficiency.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Reference Figure 1-6A blockage-proof and easy-to-clean drum screen comprises a frame 1 and a hopper 2. The frame 1 comprises a first mounting frame 3 and a second mounting frame 4 with a chute. A driving assembly is slidably provided in the first mounting frame 3, and a mounting seat 5 is slidably provided in the second mounting frame 4. First sliders 6 are provided at both ends of the mounting seat 5. The bottom of the mounting seat 5 is fixedly connected to a first spring group 7. A screen drum 8 is provided between the driving assembly and the mounting seat 5, a rotating assembly is provided in the screen drum 8, and a vibration assembly is provided in the rotating assembly. A discharge slope 9 is provided at the output end of the frame 1 corresponding to the screen drum 8, and a wire roller 10 is provided at the cylinder wall of the frame 1 corresponding to the screen drum 8. The hopper 2 is located at the input end of the screen drum 8.

[0027] It should be noted that the screen drum 8 is tilted between the frames 1, the wire roller 10 is close to the screen drum 8, and the rotating shaft of the wire roller 10 is set as a high-damping rotating shaft, so that the wire roller 10 can play a cleaning role while being driven to rotate slowly by the friction force of the screen drum 8.

[0028] Furthermore, the driving assembly includes a sliding housing 11 and a planetary gear 15 wheel set, and the second slider 12 is fixedly connected to both sides of the sliding housing 11, and the top and bottom ends of the sliding housing 11 are fixedly connected to the second spring group 13, and the second spring group 13 is fixedly connected to the top and bottom ends of the first mounting frame 3. The planetary gear 15 wheel set is fixedly installed inside the sliding housing 11, and the planetary gear 15 wheel set includes a sun gear 14 and a planetary gear 15. One side of the sun gear 14 passes through the sliding housing 11 and is rotatably connected to the motor 16. The other side of the sun gear 14 is connected to the vibration assembly, and one side of the planetary gear 15 is fixedly connected to the turntable 17. A through hole is opened in the center of the turntable 17, and the outer wall of the turntable 17 passes through the sliding housing 11 and is fixedly connected to the rotating sleeve 18.

[0029] It should be noted that the gear ratio of the planetary gear 15 set is set to 12:1.

[0030] A further advantage of adopting the above method is that the motor 16 can drive the sun gear 14 to drive the vibration component to rotate at high speed, while the planetary gears 15 can drive the rotating component and the screen drum 8 to rotate at low speed.

[0031] Furthermore, the rotating assembly includes a sleeve 19, a support ring 20 and a connecting ring 21. The support ring 20 is located at one end and the middle section of the sleeve 19, and the connecting ring 21 is located at the other end of the sleeve 19. The outer walls of the support ring 20 and the connecting ring 21 are fixedly connected with a number of pillars 22, and the pillars 22 are welded to the inner wall of the screen drum 8. The connecting ring 21 is fixedly connected with a rotating rod 23 on the side facing the frame 1, and the rotating rod 23 is rotatably connected to the mounting seat 5.

[0032] A further advantage of adopting the above method is that, under the joint action of the sleeve 19, the support ring 20 and the connecting ring 21, the vibration component can be supported to be arranged inside the rotating component, making the structure more compact.

[0033] Furthermore, the vibration assembly includes a vibration rod 24, one end of the vibration rod 24 passes through the support ring 20 and the rotating sleeve 18 and is fixedly connected to the sun gear 14, and the other end of the vibration rod 24 passes through the support ring 20 and is rotatably connected to the connecting ring 21. The vibration rod 24 is fixedly connected to the corresponding sleeve 19 with an eccentric block 25, and the size of the eccentric block 25 is smaller than the inner diameter of the sleeve 19.

[0034] A further advantage of adopting the above method is that when the vibrating rod 24 rotates at high speed, it drives the eccentric block 25 to rotate at high speed, and the rotation of the eccentric block 25 generates an unbalanced centrifugal force, which in turn causes the screen drum 8 to vibrate, achieving the effect of self-vibration. Under the joint action of the vibration component and the wire roller 10, the wet material attached to the wall of the screen drum 8 can be effectively cleaned and the sand and gravel attached together can be separated.

[0035] When the utility model is in use, the power is turned on to make the motor 16 work, the planetary gear 15 is driven to rotate by the motor 16, and the vibration rod 24 is driven to rotate at high speed by the sun gear 14. When the vibration rod 24 rotates at high speed, the eccentric block 25 is driven to rotate at high speed. The rotation of the eccentric block 25 generates an unbalanced centrifugal force, thereby causing the screen drum 8 to vibrate. At the same time, the sun gear 14 drives the planetary gear 15 to rotate at a low speed, and the planetary gear 15 drives the turntable 17 and the rotating sleeve 18 to rotate. The rotating sleeve 18 drives the rotating assembly and the screen drum 8 to rotate at a low speed, thereby achieving a self-vibration effect.

[0036] During vibration, the mounting base 5 slides along the second mounting frame 4 and is buffered by the first spring group 7. The sliding housing 11 slides along the first mounting frame 3 and is buffered by the second spring group 13. At this time, sand and gravel are put into the hopper 2. After the sand and gravel enter the screen drum 8, they slide toward the discharge slope 9 by the combined action of gravity and vibration. During the sliding process, the sand and gravel are screened by the vibration of the vibration component and the rotation of the screen drum 8. Under the action of vibration, the attached sand and gravel are separated. When a large area of ​​wet sand adheres to the screen, the wet sand falls off through the vibration of the vibration component. When the remaining small amount of attachments rotates with the screen drum 8 to the wire roller 10, they are swept away by the rotation of the wire roller 10, thereby improving the cleaning efficiency.

[0037] The qualified sand and gravel soil falls to the ground from the bottom of the screen drum 8, and the unqualified gravel is discharged from the discharge slope 9, completing the screening.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
