Description

Technical Field

[0001] This utility model belongs to the field of emulsifier production technology, and in particular to a screening device for asphalt emulsifier raw materials. Background Technology

[0002] Asphalt emulsifiers are surfactants used for emulsifying asphalt. The raw materials for asphalt emulsifiers consist of solid materials, which need to be screened before production to improve subsequent processing efficiency and effectiveness. However, traditional screening devices simply adjust the tilt angle back and forth to assist in material feeding. But with this design, a large tilt angle may lead to excessive feeding speed, affecting the uniformity and effectiveness of screening.

[0003] A search revealed a Chinese patent document (authorization announcement number CN212759657U) regarding a screening device for asphalt emulsifier raw materials. The device includes a housing with a feed inlet on one side of its upper end. Inside the housing, a first screen is positioned above the first screen, a second screen below the first screen, and a third screen below the second screen. An inclined base plate is located at the lower end of the housing, with a second discharge outlet at the connection point between the base plate and the first discharge outlet. The housing contains a shaking component to improve the screening effect. By using multiple screens, raw materials of different sizes fall through different screens from different discharge outlets, thus enabling graded screening and facilitating further processing. However, this patented screening device only adjusts the tilt angle to assist in feeding. This design, with a large tilt angle, may lead to excessive feeding speed, affecting the uniformity and effectiveness of the screening. Utility Model Content

[0004] The purpose of this invention is to provide an asphalt emulsifier raw material screening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an asphalt emulsifier raw material screening device, comprising a screening box, wherein multiple screening frames are installed on the inner wall of the screening box, and a pair of screening meshes for screening asphalt emulsifier raw materials are connected to the inner wall of the screening frames.

[0006] The outer periphery of the screening box is equipped with a U-shaped counterweight plate, and a speed-regulating motor is installed at the top of the counterweight plate. The output shaft of the speed-regulating motor is connected to a rotating rod, and a disc is connected to the side of the rotating rod. The side of the disc is rotatably connected to a rotating main board via a rotating shaft, and the rotating main board is also rotatably connected to the screening box via a rotating shaft.

[0007] Two hollow plates are welded to the bottom of the screening box. The inner cavity of the hollow plate is equipped with a movable plate. Multiple springs connect the movable plate to the screening box. Multiple rotating rods are rotatably connected between the two movable plates. Multiple eccentric wheels for vibrating the screening box are connected to the outer periphery of the rotating rods. Multiple rotary motors that provide power to the rotating rods are installed on the outer periphery of the movable plate.

[0008] As a preferred implementation, multiple filter boxes are arranged side by side and tilted, with the mesh count of the multiple filter boxes increasing sequentially from top to bottom.

[0009] As a preferred embodiment, the inner wall of the screening box is welded with an inclined auxiliary plate, and the side of the screening box is connected to several material hoppers that are adapted to the screening frame and the auxiliary plate.

[0010] As a preferred embodiment, the inner wall of the screening box is connected to multiple inclined baffles corresponding to the positions of the screening frames.

[0011] As a preferred embodiment, a feed hopper for asphalt emulsifier raw materials is embedded in the top of the screening box, and an adjusting plate is rotatably connected to the inner wall of the feed hopper.

[0012] As a preferred embodiment, a threaded tube is embedded in the side of the feed hopper, and the threaded tube is threadedly connected to an adjusting threaded rod for lifting the adjusting plate.

[0013] As a preferred embodiment, a viewing window is embedded in the side of the screening box.

[0014] As a preferred embodiment, the outer periphery of the screening box is connected to multiple sliding rods, and the inner wall of the counterweight plate is connected to multiple arc-shaped sliding plates that are adapted to the sliding rods.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This asphalt emulsifier raw material screening device benefits from the design of a speed-regulating motor. The speed-regulating motor drives the rotating rod and the disc to rotate, which in turn drives the rotating main board to move, causing the screening box to move back and forth. This results in the back-and-forth shaking of the screening frame and the screening screen. Compared with the angle adjustment method, the change in the screening screen is more gentle, ensuring the uniformity of the screening of asphalt emulsifier raw materials.

[0017] This asphalt emulsifier raw material screening device benefits from the design of a rotary motor. The rotary motor drives the rotating rod to rotate, which in turn drives the eccentric wheel to rotate. During the rotation of the eccentric wheel, it intermittently hits and vibrates the screening box, indirectly providing vibration to the filter screen. Combined with the back-and-forth shaking, it greatly improves the filtration effect of the filter screen.

[0018] This asphalt emulsifier raw material screening device benefits from the design of the feed hopper and the adjusting plate. By rotating the adjusting screw rod, the adjusting plate is lifted, which changes the feed rate of the feed hopper, thus adapting to the screening needs of various raw materials.

[0019] This asphalt emulsifier raw material screening device can shake and vibrate to improve screening effect and screening uniformity. Attached Figure Description

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] The connection method can adopt existing methods such as bonding, welding, and bolting, depending on the actual needs. Techniques, methods and equipment known to those skilled in the art may not be discussed in detail. However, where appropriate, the techniques, methods and equipment should be regarded as part of the specification. The proportions of the components in the drawings are for reference only and can be adjusted to a certain extent according to the actual use.

[0031] This application is in an environment of vibration and shaking. When each structure is fixed, its stability must be ensured. Then, the whole system should be regularly maintained and repaired. Structures that are easily damaged or affected should be replaced and repaired regularly.

[0032] Please see Figures 1 to 4 As shown, an asphalt emulsifier raw material screening device is provided. In this embodiment, it includes a screening box 1. Multiple screening frames 2 are installed on the inner wall of the screening box 1. Screening mesh 3 for screening asphalt emulsifier raw materials is connected to the inner wall of the screening frames 2. The multiple screening frames 2 are arranged side by side and are inclined. The mesh count of the multiple screening mesh 3 increases from top to bottom. Only two screening mesh 3 are shown in the figure. The actual number is not based on the figure and should be selected according to actual needs.

[0033] The outer periphery of the screening box 1 is provided with a U-shaped counterweight plate 4. Multiple sliding rods 5 are connected to the outer periphery of the screening box 1. Multiple arc-shaped sliding plates 6 that are adapted to the sliding rods 5 are connected to the inner wall of the counterweight plate 4. A speed-regulating motor 7 is also installed at the top of the counterweight plate 4. The output shaft of the speed-regulating motor 7 is connected to a rotating rod. A disc 8 is connected to the side of the rotating rod. A rotating main plate 9 is rotatably connected to the side of the disc 8 through a rotating shaft. The rotating main plate 9 is also rotatably connected to the screening box 1 through a rotating shaft. The asphalt emulsifier raw material to be screened is introduced into the feed hopper 19 by the feeding device, and then falls into the screening screen 3 at the top. The speed-regulating motor 7 drives the rotating rod and the disc 8 to rotate, which drives the rotating main plate 9 to move, so that the screening box 1 moves back and forth, thereby realizing the back and forth shaking of the screening frame 2 and the screening screen 3. The overall structure is similar to a reciprocating structure. The size of the disc 8 should not be too large, and the length of the rotating main plate 9 should not be too short to ensure that the reciprocating motion can be realized.

[0034] Two hollow plates 10 are welded to the bottom of the screening box 1. A movable plate 11 is provided in the inner cavity of the hollow plate 10. Multiple springs 12 are connected between the movable plate 11 and the screening box 1. Multiple rotating rods 13 are rotatably connected between the two movable plates 11. Multiple eccentric wheels 14 for vibrating the screening box 1 are connected to the outer periphery of the rotating rods 13. Multiple rotary motors 15 that provide power to the rotating rods 13 are installed on the outer periphery of the movable plate 11. The rotary motors 15 drive the rotating rods 13 to rotate, which in turn drives the eccentric wheels 14 to rotate. During the rotation, the eccentric wheels 14 intermittently strike and vibrate the screening box 1.

[0035] The inner wall of the screening box 1 is welded with an inclined auxiliary plate 16. Several material hoppers 17 adapted to the screening frame 2 and the auxiliary plate 16 are connected to the side of the screening box 1. A receiving device or movable device corresponding to the material hopper 17 is set on one side of the screening box 1 to allow the screening box 1 to move. Several inclined baffles 18 corresponding to the positions of the screening frame 2 are connected to the inner wall of the screening box 1. The screening mesh 3 can screen the asphalt emulsifier raw materials. After the raw materials close to the material hopper 17 are blocked by the baffles 18, they fall onto the screening mesh 3 below, increasing the screening stroke of the screening mesh 3. Finally, raw materials of different sizes fall into the material hoppers 17 at different positions.

[0036] For feeding and adjustment, a feed hopper 19 for asphalt emulsifier raw material is embedded in the top of the screening box 1. An adjustment plate 20 is rotatably connected to the inner wall of the feed hopper 19. A threaded pipe 21 is embedded in the side of the feed hopper 19. The threaded pipe 21 is threadedly connected to an adjustment threaded rod 22 for lifting the adjustment plate 20.

[0037] The side of the screening box 1 is fitted with a viewing window. The screening box 1 can also be connected to necessary equipment such as a vacuum cleaner. These are not related to the innovation of this application, so they will not be described in detail.

[0038] Speed-regulating motor 7 and rotary motor 15 are both conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model.

[0039] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0040] Working principle

[0041] The asphalt emulsifier raw material screening device, according to the screening requirements of the asphalt emulsifier raw material, first rotates the adjusting screw rod 22, thereby lifting the adjusting plate 20, changing the feeding amount of the feed hopper 19, turning on the speed regulating motor 7 and the rotary motor 15, and then using the feeding equipment to introduce the asphalt emulsifier raw material to be screened into the feed hopper 19, and then falling into the uppermost screening screen 3. The speed regulating motor 7 drives the rotating rod and the disc 8 to rotate, which drives the rotating main plate 9 to move, so that the screening box 1 moves back and forth, thereby realizing the back and forth shaking of the screening frame 2 and the screening screen 3. The rotary motor 15 drives the rotating rod 13 to rotate, which in turn drives the eccentric wheel 14 to rotate. During the rotation process, the eccentric wheel 14 intermittently hits and vibrates the screening box 1.

[0042] During this process, the screening mesh 3 can screen the asphalt emulsifier raw materials. The raw materials close to the aggregate hopper 17 are blocked by the baffle plate 18 and fall onto the screening mesh 3 below, increasing the screening stroke of the screening mesh 3. Finally, raw materials of different sizes fall into the aggregate hopper 17 at different positions.
