Description

Technical Field

[0001] This utility model relates to the field of waste sorting technology, specifically to a vibrating screening device for aged waste. Background Technology

[0002] Vibrating screening equipment for aged waste is an environmentally friendly device specifically designed for treating long-term accumulated waste. It is also one of the key technologies in aged waste treatment. Through physical screening, it achieves resource classification and recycling. Its uppermost screen bar is the primary screening layer, composed of parallel bars. Through specific spacing, it blocks large materials such as stones and metals, while allowing fine particles such as organic matter and sand to pass through, thus completing the separation of coarse and fine materials. The vibration principle of the equipment relies on a vibrating motor or vibrator to generate high-frequency reciprocating motion, combined with a spring buffer device, so that the material jumps forward on the screen surface. Fine particles pass through the screen holes, while coarse particles are discharged along the screen surface, achieving efficient classification. This equipment can reduce landfill volume and promote resource recycling.

[0003] During use, the screen bars of the vibrating screening equipment for aged waste have sharp ends that can easily get tangled in plastic bags in the aged waste, affecting the subsequent dropping of waste. Workers need to use a rod to remove the tangled garbage bags. Because the equipment is vibrating at high speed, the rod may touch the equipment, posing a safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating screening device for aged waste to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibrating screening device for aged waste, comprising a screen body, a support, a screen plate body, and a screen bar body, and further comprising:

[0006] A transverse column is provided through the surface of the screen body, and the screen bar body is provided through the surface of the transverse column. Several through holes are provided through the surface of the screen bar body. The interior of the screen bar body is hollow, and the through holes are connected to the interior of the screen bar body. A ring is fixed inside the through hole. A sealing cap is fixed on one side of the ring body by a spring hinge. A connecting pipe is also provided inside the transverse column, and the interior of the screen bar body is connected to the connecting pipe.

[0007] A long pipe is bolted to one side of the support. Several vertical pipes are connected to the top of the long pipe. Solenoid valves are installed on the surface of the vertical pipes. A flexible hose is connected to the top of the vertical pipes, and the other end of the flexible hose is connected to a connecting pipe.

[0012] Preferably, the sealing cap is circular and larger than the inner diameter of the ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model, through the arrangement of a long pipe, a solenoid valve, a vertical pipe, a flexible hose, and a connecting pipe, can form a pipeline and connect to an external air supply facility to supply air to the interior of the screen bar body.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 As shown, a vibrating screening device for aged waste includes a screen body 1, a support 2, a screen plate body 3, and screen bar bodies 5. The screen plate body 3 is bolted to the inside of the screen body 1. The support 2 and the screen body 1 are fixed to each other by a spring damping device. The screen body 1 uses a vibrating motor or exciter as a power source. Centrifugal force is generated by the rotation of an eccentric block, driving the screen body 1 to perform high-frequency reciprocating motion. The vibration energy is transmitted to the support 2 through the spring buffer device to reduce the impact on the ground and ensure the stable vibration of the screen body 1. This is a brief description of the principle of vibrating screening equipment in the prior art, and will not be described in detail later. Horizontal columns 4 are provided through the surface of the screen body 1, and screen bar bodies 5 are provided through the surface of the horizontal columns 4. There are several horizontal columns 4 distributed in a stepped manner, thus making the screen bar bodies 5 distributed in a stepped manner. The interior of the screen bar bodies 5 is hollow, and several through holes 7 are opened through the surface of the screen bar bodies 5. The through holes 7 are connected to the screen bar bodies. The internal parts of the screen body 5 are interconnected. A ring body 8 is fixed inside the through hole 7. A sealing cover 9 is fixed to one side of the ring body 8 by a spring hinge. The sealing cover 9 is circular and larger than the inner diameter of the ring body 8. When no force is applied, the spring hinge allows the sealing cover 9 to fit tightly against the surface of the ring body 8, thus closing it. A connecting pipe 6 is also provided inside the transverse column 4, and the internal parts of the screen body 5 are interconnected with the connecting pipe 6. A long pipe 10 is bolted to one side of the support 2. Several vertical pipes 12 are connected to the top of the long pipe 10. A solenoid valve 11 is installed on the surface of the vertical pipe 12 to control the opening and closing of the vertical pipe 12. A flexible hose 13 is connected to the top of the vertical pipe 12, and the other end of the flexible hose 13 is connected to the connecting pipe 6, connecting the long pipe 10 and the connecting pipe 6. A fixing sleeve 15 is also bolted to one side of the screen body 1, and the fixing sleeve 15 is fitted and fixed to the surface of the connecting pipe 6 to increase the firmness of the fixation with the connecting pipe 6.

[0025] During operation, the long pipe 10 is connected to an external air supply facility, such as an air storage tank connected to an air pump. Pressurized gas is supplied into the long pipe 10 through the external air supply facility. The screen body 1 vibrates up and down, which drives the screen plate body 3, the transverse column 4 and the screen bar body 5 to move up and down, sorting out the old waste. The top layer is the larger waste, such as large clods of soil and stones, which eventually falls into the conveyor belt of the equipment (not shown in the figure, the height of the conveyor belt is slightly lower than the height of the screen bar body 5 at the end). Smaller waste is screened through the screen plate body 3.

[0026] During the screening process, if plastic bags or other garbage become entangled on the end of the screen bar body 5, the solenoid valve 11 on the corresponding pipeline is opened. At this time, gas enters the interior of the screen bar body 5 after passing through the vertical pipe 12, the flexible hose 13, and the connecting pipe 6, and pushes the sealing cover 9 to open. The gas is blown out from the through hole 7, blowing away the plastic bag and preventing it from continuing to become entangled. When there is no gas, the sealing cover 9 closes to prevent a large amount of impurities from entering the interior. A fence 16 is also attached to the top of the screen body 1. A horizontal bar 17 is attached to the upper surface of the fence 16 to prevent plastic bag garbage from being blown out of the outside of the device. A transparent window 14 is also installed on the surface of the fence 16 to facilitate workers to observe the interior. At the same time, in actual operation, a support is set up next to the device so that workers can approach the top of the device. The transparent window 14 is made of tempered glass, and under vibration, the transparent window 14 will not be covered by impurities. Therefore, after the plastic bag is blown away, it will detach from the end of the screen bar body 5, and workers do not need to use a long pole to remove the plastic bag, which is safer.
