Technical Field
[0001] The utility model belongs to the technical field of asphalt, and in particular relates to asphalt particle screening equipment used for asphalt. Background Art
[0002] Oil asphalt is the residue after crude oil distillation, and natural asphalt is stored underground. Some of it forms mineral layers or accumulates on the surface of the earth's crust. Asphalt is mainly used in industries such as coatings, plastics, rubber, and road paving. When processing granular petroleum asphalt, the asphalt needs to be screened, and only asphalt particles that meet the requirements can be put into use.
[0003] In the process of realizing the present application, the inventors found that there are at least the following problems in the technology: the existing equipment is very likely to cause asphalt clogging when filtering asphalt, affecting the screening effect; therefore, further improvements can be made. Utility Model Content
[0004] In view of the problem that the existing equipment in the background technology is very likely to cause asphalt clogging and affect the screening effect when filtering asphalt, the present application provides an asphalt particle screening device for asphalt. The utility model uses a telescopic picking component to shake the screening cylinder up and down, and then drives the screening cylinder itself to roll through a driving motor to increase the screening efficiency. A cleaning component is provided to clean the asphalt adhered to the side wall of the screening cylinder for efficient screening.
[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0006] Asphalt particle screening equipment for asphalt includes a screening box, an upwardly penetrating screening cavity is provided inside the screening box, a horizontally placed screening drum is provided inside the screening box, a driving motor for driving the screening drum to rotate is provided on the outside of the screening box, a feeding port connected to the screening drum is provided on the other side of the screening box opposite to the driving motor, a "7"-shaped supporting frame is provided on one side of the left and right outer sides of the screening box close to the top, the horizontal end of the supporting frame faces the top of the screening box, a vertically placed telescopic picking component for clamping the screening drum is provided at the bottom of the horizontal end of the supporting frame, two groups of cleaning components for cleaning the screening box are provided inside the screening box below the screening drum, and discharge ports connected to the screening cavity and the outside are provided at both ends of the bottom of the screening box.
[0007] Furthermore, a cavity is provided inside the screening cylinder, and a plurality of filter holes connecting the cavity and the screening cavity are distributed on the outer wall of the screening cylinder. Connecting cylinders matching with the cavity are provided at both ends of the screening cylinder, one side of the connecting cylinder is connected to the driving motor, and the other side is connected to the cavity and the feed port.
[0008] Furthermore, the telescopic picking assembly includes a telescopic rod arranged at the bottom of the horizontal end of the support frame, and two grabbing clamps are provided at the bottom of the telescopic rod. The grabbing clamps are cocentrically distributed on the outside of the connecting tube with the connecting tube, and the top of the grabbing clamp is rotatably connected to the bottom of the telescopic rod. The side of the grabbing clamp facing the connecting tube is inlaid with multiple balls.
[0009] Furthermore, the left and right outer side walls of the screening box are provided with slideways for accommodating the driving motor and the up and down movement of the feed port.
[0010] Furthermore, the cleaning assembly includes an arc rod arranged at the front and rear ends of the bottom of the screening cylinder, the arc rod is placed horizontally left and right, the arc rod is concentric with the screening cylinder, and a plurality of cleaning wheels are rotatably connected to the arc rod. When the cleaning wheel rotates, the outer wall of the screening cylinder is cleaned.
[0011] Furthermore, an arc-shaped convex plate with a high middle and low sides is provided at the bottom of the screening box to facilitate the screened asphalt to flow to the discharge ports on both sides and prevent the asphalt from sticking inside the screening box.
[0012] The beneficial effects of the utility model are:
[0013] 1. The driving motor drives the screening drum to rotate, and the asphalt to be screened enters from the feed port at the other end. As the screening drum rolls, the asphalt that meets the standards flows out from the filter holes of the screening drum into the screening box, and the large particles of asphalt remain inside the screening drum.
[0014] 2. Before the screening cylinder rotates, place the grabbing clamp on the connecting cylinders on both sides of the screening cylinder, adjust the grabbing clamp angle to grab the connecting cylinder, and the outer wall of the connecting cylinder is provided with a groove (not shown) to accommodate the grabbing clamp limit. After grabbing, start the driving motor to drive the screening cylinder to rotate. The balls roll together when the screening cylinder rotates, reducing the friction between the grabbing clamp and the connecting cylinder. The telescopic rod is driven by the internal controller of the equipment to extend and retract up and down. The telescopic rod is an electronic telescopic rod. The screening cylinder is driven to rotate up and down by the telescopic rod while it rotates itself, ensuring the high efficiency of screening.
[0015] 3. The cleaning wheel rotates in the opposite direction to the screening drum, which makes it easier to clean the asphalt adhering to the outer wall of the screening drum and increase the screening efficiency of the screening drum. BRIEF DESCRIPTION OF THE DRAWINGS
