Description

Technical Field

[0001] This utility model relates to the field of asphalt manufacturing technology, and in particular to a screening device for processing solid particle asphalt. Background Technology

[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, appearing liquid with a black surface, and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementing material. Asphalt can be mainly classified into three types: coal tar pitch, petroleum asphalt, and natural asphalt. Coal tar pitch is a byproduct of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, sometimes forming mineral layers or accumulating on the earth's surface. Asphalt is mainly used in the coatings, plastics, and rubber industries, as well as in road paving.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] refer to Figure 1 A screening device for processing solid particle asphalt includes a support frame 1 for supporting other components. A conveying device 2 is provided on one side of the top of the support frame 1. The conveying device 2 is used to transport the asphalt raw material that has not been screened to the primary screening device 4 for preliminary screening.

[0023] refer to Figure 1 The primary screening device 4 can perform preliminary screening of asphalt material, and can prioritize the preliminary screening of semi-solid asphalt and solid asphalt. The primary screening device 4 is located on one side of the conveying device 2. The asphalt material conveyed by the conveying device 2 will initially accumulate on the primary screening device 4. The asphalt raw materials are initially screened by the screening brush 19 and the primary screening screen 6. The primary screening device 4 includes the primary screening screen 6 set at the top. The primary screening screen 6 can screen out solid asphalt that is too fine.

[0024] refer to Figure 1 and Figure 3 The primary screening device 4 has a first motor 5 on its back, which drives the screening device to rotate. The speed of the primary screening can be controlled by controlling the speed of the first motor 5. The primary screening device 4 has a screening roller 18 on the side opposite to the conveying device 2. The rotation of the screening roller 18 drives the screening brush 19 to rotate. The screening brush 19 is evenly arranged around the screening roller 18. The screening brush 19 is arc-shaped. The arc shape of the screening brush 19 can quickly pick up the asphalt and screen it. The arc of the screening brush 19 is between 15° and 35°, which can better make the semi-solid material adhere to the screening brush 19. The screening roller 18 is fixedly connected to the screening shaft 17. The screening device is driven to rotate by the motor.

[0025] refer to Figure 1 and Figure 3 By setting up a screening roller 18 and a screening brush 19, when semi-solid asphalt passes through the screening brush 19, it will adhere to the screening brush 19. After the asphalt solidifies, it will pass through the screening brush 19 into the first screening chamber 7 for screening. This effectively screens solid and semi-solid asphalt particles. The semi-solid asphalt particles are not easily bound to solid asphalt particles to form spheres, thus not affecting the use. refer to Figure 1The primary screening device 4 is in the shape of an inverted convex character. The primary screening device 4 is hollow, so that very fine solid asphalt can pass through the screening screen and enter the interior of the primary screening device 4, and then be discharged through the bottom of the primary screening device 4. The primary screening screen 6 is fixedly connected to the primary screening device 4 by screws, so that the primary screening screen 6 can be easily disassembled for cleaning and maintenance. The primary screening screen 6 is embedded in the top of the primary screening device 4, so as to protect the primary screening screen 6 and prevent it from being damaged by other external forces.

[0026] refer to Figure 1 and Figure 3 The screening shaft 17 is rotatably connected to the primary screening shaft at both ends. Both ends of the screening shaft 17 pass through the primary screening device 4, so that the primary screening device 4 can limit and fix the screening shaft 17, effectively preventing the screening shaft 17 from falling off. The end of the screening shaft 17 near the first motor 5 is connected to the first motor 5. The first motor 5 drives the screening shaft 17 to rotate, and the screening shaft 17 drives the screening roller 18 and the screening brush 19 to rotate for preliminary screening.

[0027] refer to Figure 2 The conveying device 2 is equipped with a conveyor belt 3, which is used to transport asphalt raw materials. The surface of the conveyor belt 3 is equipped with a friction pad 16, which can increase the friction between the conveyor belt 3 and the asphalt raw material and transport the asphalt raw material more effectively. One end of the conveying device 2 is equipped with a transmission shaft 15, which is rotatably connected to the conveying device. The transmission shaft 15 is electrically driven by an internal motor, which can drive the conveyor belt 3 to transport raw materials.

[0028] refer to Figure 1 The conveying device 2 is provided with a first screening chamber 7 on one side. The first screening chamber 7 is located on the side opposite to the conveying device 2. The first screening chamber 7 can screen the asphalt that has been initially screened and can transport small particles of asphalt solids to the discharge port 14 through rolling screening.

[0029] refer to Figure 1 The first screening chamber 7 is provided with a second screening chamber 8, a third screening chamber 9, a fourth screening chamber 10, and a fifth screening chamber 11 in sequence on one side. The second screening chamber 8, the third screening chamber 9, the fourth screening chamber 10, and the fifth screening chamber 11 are all located on the side opposite to the conveying device 2. The second screening chamber, the third screening chamber 9, the fourth screening chamber 10, and the fifth screening chamber 11 can sequentially screen solid asphalt of different sizes, effectively realizing the function of graded screening. In different scenarios, different sizes of solid asphalt need to be used, and the second screening chamber, the third screening chamber 9, the fourth screening chamber 10, and the fifth screening chamber 11 can effectively screen and separate them.

[0030] refer to Figure 1The first screening chamber 7, the second screening chamber 8, the third screening chamber 9, the fourth screening chamber 10, and the fifth screening chamber 11 are all cylindrical. The cylindrical shape allows the solid asphalt to roll fully within the first screening chamber 7, the second screening chamber 8, the third screening chamber 9, the fourth screening chamber 10, and the fifth screening chamber 11, thereby making the screening more accurate. There are multiple evenly spaced channels on the first screening chamber 7, the second screening chamber 8, the third screening chamber 9, the fourth screening chamber 10, and the fifth screening chamber 11. After being screened, the solid asphalt is transported to the discharge port 14 through the channels. The weight of the solid asphalt itself allows it to accumulate at the bottom of the first screening chamber 7, the second screening chamber 8, the third screening chamber 9, the fourth screening chamber 10, and the fifth screening chamber 11, so that the solid asphalt will not splash out from other positions and can be output from the discharge port 14 after screening.

[0031] refer to Figure 1 The sizes of the through slots on the first screening chamber 7, the second screening chamber 8, the third screening chamber 9, the fourth screening chamber 10, and the fifth screening chamber 11 increase sequentially, thus enabling the screening of solid asphalt from small to large, and continuously realizing the function of solid asphalt screening. The fifth screening chamber 11 is equipped with a second motor 12 and a transmission device 13 on one side. The second motor 12 and the transmission device 13 control the rotation of the first screening chamber 7, the second screening chamber 8, the third screening chamber 9, the fourth screening chamber 10, and the fifth screening chamber 11. The second motor 12 drives the fifth screening chamber 11 to rotate through the transmission device 13. The fifth screening chamber 11 is integrated with the first screening chamber 7, the second screening chamber 8, the third screening chamber 9, and the fourth screening chamber 10, so they can rotate synchronously to realize the grading and screening function.

[0032] refer to Figure 1 and Figure 4 The first screening chamber 7, the second screening chamber 8, the third screening chamber 9, the fourth screening chamber 10 and the fifth screening chamber 11 are provided with discharge ports 14 at their bottom ends. The screened solid asphalt is output through the discharge port 14. The discharge port 14 is set at an inclination of 45°, so that the solid asphalt can be transported by its own weight, which can prevent the solid asphalt from accumulating at the discharge port 14.

[0033] refer to Figure 4 The discharge port 14 is equipped with multiple discharge rollers 20. These rollers facilitate the sliding output of solid asphalt from the discharge port 14, preventing its accumulation. The spacing between the multiple discharge rollers 20 is consistent, ensuring a uniform output rate of solid asphalt. Furthermore, when terms such as "first," "second," and "third" are used in this specification to describe various features, these terms are used only to distinguish these features and should not be construed as indicating or implying the correlation, relative importance, or number of features.

[0034] In addition, this application specification describes exemplary embodiments by referring to idealized exemplary cross-sectional views and / or plan views and / or perspective views.
