Description

Technical Field

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

[0002] Asphalt is an organic cementitious material with multiple properties and wide applications. It is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It can be in liquid, semi-solid, or solid states and is widely used in road engineering, building engineering, and water conservancy projects.

[0003] Different forms of asphalt are required in different application scenarios, with solid asphalt having the widest range of applications and the largest quantity used. Screening of solid asphalt is therefore essential. Chinese Patent Publication No. CN 220760036 U discloses a vibrating screen for asphalt production, belonging to the technical field of vibrating screens. This vibrating screen for asphalt production includes a screen box and a cleaning mechanism. A screen mesh is installed on the screen box. The cleaning mechanism includes a first motor, a lead screw, a limiting rod, a slider, a turntable, and a hard brush. The first motor is fixedly connected to the outside of the screen box; the lead screw is fixedly connected to the output end of the first motor; the limiting rod is fixedly connected to the inner wall of the screen box; the slider is threadedly connected to the lead screw and slidably connected to the limiting rod; the turntable is rotatably connected to the slider; and the hard brush is fixedly connected to the turntable.

[0004] The aforementioned screening machine is suitable for screening solid asphalt. However, its screen box and screen are both inclined and the inclination direction and angle are the same. After screening the asphalt, the screened asphalt moves in the same direction simultaneously above and below the screen. This not only makes subsequent collection difficult, but also easily causes the screened asphalt to mix again, making it impossible for the asphalt screening work to proceed normally.

Detailed Implementation

[0032] 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.

[0033] Please see Figure 1-10 In this embodiment of the present invention, a vibrating screening device for asphalt production includes a screening component 3, a belt conveyor 4 below the screening component 3, and a storage component 1 above the screening component 3, and the storage component 1 is fixedly connected to the support component 2.

[0034] The screening assembly 3 includes an outer frame 31, with a screen plate 312 fixedly connected to the bottom inner side of the outer frame 31; connecting rods 32 are fixedly connected to the upper ends of both ends of the outer frame 31, and both ends of the two connecting rods 32 extend to the outer side of the outer frame 31 and are fixedly connected to sleeve seats 33; springs 34 are fixedly connected to the bottom ends of the multiple sleeve seats 33; the support assembly 2 includes a main frame 21, with inclined inner frames 22 symmetrically fixedly connected to the inner side of the main frame 21, and multiple connecting seats 23 are fixedly connected to the top of the two inner frames 22; sleeves 24 are fixedly connected to the top ends of the multiple connecting seats 23; the lower ends of the multiple springs 34 are respectively located inside the multiple sleeves 24 and are fixedly connected to the bottom of the multiple sleeves 24 respectively.

[0035] The belt conveyor 4 is inclined, and a gathering bucket 313 is provided below the outer frame 31. The two sides of the gathering bucket 313 are fixedly connected to two inner frames 22 respectively, and the gathering bucket 313 is located at the lower end of the belt conveyor 4.

[0036] By adopting the above technical solution, the transmission shaft 35 can drive the counterweights 37 at both ends to rotate during the rotation process. The center of gravity of the two counterweights 37 is displaced during the rotation process, which causes the outer frame 31 and the screen plate 312 to shake, allowing the screen plate 312 to screen the asphalt. Multiple springs 34 can increase the shaking amplitude of the screen plate 312, thereby increasing the screening effect of the screen plate 312 on the asphalt.

[0037] In this embodiment, a second transmission shaft 35 is provided at the upper middle part of the outer frame 31. Both ends of the second transmission shaft 35 are rotatably connected to the outer frame 31, and both ends of the second transmission shaft 35 are fixedly connected to counterweights 37. One end of the second transmission shaft 35 is fixedly connected to a driven pulley 36, and the driven pulley 36 and the two counterweights 37 are located on the outside of the outer frame 31.

[0038] The driven pulley 36 is provided with a driving pulley 38 on one side, and the driving pulley 38 is connected to the driven pulley 36 through a second belt 39; a third drive shaft 30 is coaxially fixedly connected to the driving pulley 38, and the end of the third drive shaft 30 away from the driving pulley 38 is fixedly connected to the output shaft of the second motor 310; the bottom of the second motor 310 is fixedly connected to the top of the connecting plate 311, and the bottom of the connecting plate 311 is fixedly connected to the top of the outer frame 31.

[0039] A guide plate 25 is fixedly connected to one side of the lower end of the main frame 21. The guide plate 25 is inclined and located above the lower end of the belt conveyor 4.

[0040] By adopting the above technical solution, the asphalt passing through the sieve plate 312 falls through the collecting hopper 313 to the lower end of the belt conveyor 4, and is then transported away by the belt conveyor 4. The asphalt that does not pass through the sieve plate 312 slides down the inclined sieve plate 312 into the guide plate 25, and is finally collected by the guide plate 25. This achieves the separation and independent processing of the screened asphalt, preventing the screened asphalt from being mixed again.

[0041] In this embodiment, the storage component 1 includes a hopper 11, which is located above the outer frame 31, and the upper outer side of the hopper 11 is fixedly connected to the upper end of the main frame 21; a gate 19 is movably connected to the lower end of the hopper 11, and one end of the gate 19 extending to the outside of the hopper 11 is fixedly connected to two cylinders 10, and the bottom of the two cylinders 10 is fixedly connected to the main frame 21.

[0042] The inner side of the hopper 11 is evenly provided with a plurality of drive shafts 13, and a plurality of stirring racks 12 are fixedly connected to each of the plurality of drive shafts 13; both ends of the plurality of drive shafts 13 are rotatably connected to the hopper 11.

[0043] Both ends of the plurality of drive shafts 13 extend to the outside of the hopper 11 and are rotatably connected to the plurality of bearing seats 14 respectively; the bottom of the plurality of bearing seats 14 is fixedly connected to the main frame 21; one end of the plurality of drive shafts 13 is coaxially fixedly connected to a pulley 15, and the pulleys 15 located on the same side are connected to each other by a belt 16; one end of the plurality of drive shafts 13 located at the lower end of the hopper 11 is fixedly connected to the output end of the plurality of reducers 17 respectively, the input end of the plurality of reducers 17 is fixedly connected to the output shaft of the plurality of motors 18 respectively, and the bottom of the plurality of reducers 17 and the plurality of motors 18 is fixedly connected to the main frame 21.

[0044] By adopting the above technical solution, multiple drive shafts 13 drive multiple mixing racks 12 to rotate during the rotation process. When the multiple mixing racks 12 rotate, they can stir the asphalt in the hopper 11 to prevent the asphalt from solidifying or clumping in the hopper 11. The cylinder 10, together with the gate 19, can block the discharge port at the bottom of the hopper 11. When not performing filtration, the gate 19 can prevent the asphalt in the hopper 11 from falling onto the screen plate 312.

[0045] The working principle of this utility model is as follows: During the rotation of the transmission shaft 35, it can drive the counterweights 37 at both ends to rotate. During the rotation of the two counterweights 37, the center of gravity of the two counterweights 37 is displaced, which causes the outer frame 31 and the screen plate 312 to shake, allowing the screen plate 312 to screen the asphalt; multiple springs 34 can increase the shaking amplitude of the screen plate 312, thereby increasing the screening effect of the screen plate 312 on the asphalt.

[0046] Asphalt passing through the sieve plate 312 falls through the collecting hopper 313 to the lower end of the belt conveyor 4, and is then transported away by the belt conveyor 4. Asphalt that does not pass through the sieve plate 312 slides down the inclined sieve plate 312 into the guide plate 25, and is finally collected by the guide plate 25, so as to separate and process the screened asphalt independently and prevent the screened asphalt from mixing again.

[0047] Multiple drive shafts 13 rotate, driving multiple mixing racks 12 to rotate. When the multiple mixing racks 12 rotate, they can stir the asphalt in the hopper 11, preventing the asphalt from solidifying or clumping in the hopper 11. The cylinder 10, together with the gate 19, can block the discharge port at the bottom of the hopper 11. When not performing filtration, the gate 19 can prevent the asphalt in the hopper 11 from falling onto the screen plate 312.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
