technical field

The utility model relates to the technical field of mixing equipment for an asphalt mixing station, in particular to a mixing cylinder for an asphalt mixing station.

Background technique

Asphalt mixing plant, also known as asphalt concrete mixing plant, asphalt concrete mixing plant. Refers to complete sets of equipment for mass production of asphalt concrete. According to the stirring method, it can be divided into forced intermittent type and continuous production type; according to the transportation method, it can be divided into fixed type, semi-fixed type and mobile type.

The Chinese invention patent with publication number CN105350431A discloses an asphalt mixing plant, which includes a feeding device, a drying device, a stirring mechanism and a finished product warehouse that are connected in sequence. Dry tower and hot material elevator, wherein the cold material elevator is communicated with the discharge port of the feeding device, and the discharge port of the hot material elevator is communicated with the feed port of the stirring mechanism .

The above-mentioned prior art solutions have the following defects: when the raw materials such as asphalt are stirred and mixed in the stirring mechanism, because the asphalt has a certain viscosity, when it is sputtered on the inner wall of the stirring mechanism, it adheres to the stirring mechanism after a period of time after the stirring is completed. The asphalt on the inner wall accumulates a lot, and it will solidify on the inner wall of the mixing tank after a long time, which is difficult to clean, resulting in low utilization of asphalt.

Utility model content

Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a mixing tank for an asphalt mixing station, which has the effect of cleaning up the residual and solidified asphalt on the inner wall of the mixing tank.

The above-mentioned utility model purpose of the present utility model is achieved through the following technical solutions:

A mixing cylinder for an asphalt mixing station comprises a cylinder body, a discharge port is arranged at the bottom of the cylinder body, a scraper is arranged in the cylinder body to scrape the inner wall of the cylinder towards the direction of the discharge port, and an inlet port is arranged on the side wall of the cylinder body. Hot oil coil for hot oil.

By adopting the above technical solution, when the cylinder is cleaned, hot oil is introduced into the hot oil coil, the hot oil coil heats the side wall of the cylinder, the asphalt attached to the inner wall of the cylinder is softened, and the scraper will The residual asphalt on the inner wall of the cylinder is scraped in the direction of the discharge port, and the residual asphalt is cleaned out of the cylinder, so that the asphalt solidified on the cylinder can be softened and cleaned up.

In a preferred example of the present invention, the scraper can be further configured as follows: the scraper is a rectangular frame, which is closely attached to the inner wall of the cylinder; The block and the scraper are fixed on the sliding block, the sliding block is fixed with the output end of the hydraulic cylinder, and the length of the sliding block is not less than the sum of the lengths of the chute and the output end of the hydraulic cylinder.

By adopting the above technical solution, when the output end of the hydraulic cylinder is extended or shortened, the slider slides in the chute, the scraper scrapes up and down in the cylinder with the slider, and when the hydraulic cylinder drives the slider to move When sliding in the chute, no matter where the scraper slides to the cylinder body, the slider will not expose the chute, nor will the residue in the cylinder slip out of the chute.

In a preferred example of the present invention, the length of the position of the fixed scraper of the sliding block from the bottom end of the sliding block and the length of the output end of the hydraulic cylinder are equal to the height of the cylinder body.

By adopting the above technical solution, when the hydraulic cylinder starts to start, the scraper slides from the top of the cylinder to the bottom, and the output end of the hydraulic cylinder has a sufficient telescopic length. When the output end of the hydraulic cylinder is extended, the scraper is located at the top of the cylinder body, and when the output end of the hydraulic cylinder is shortened, the scraper slides from the top of the cylinder body to the bottom, so that the asphalt residue on the side wall of the cylinder body can be completely cleaned .

In a preferred example of the present invention, the scraper can be further configured as follows: the scraper is fixed in the center of the slider, the length of the output end of the hydraulic cylinder is equal to the distance from the top to the bottom of the cylinder body, and the hydraulic cylinder is stationary.

By adopting the above technical solution, the output end of the hydraulic cylinder moves to drive the slider to move, so the scraper fixed on the slider slides from the top to the bottom along the side wall of the cylinder body,

In a preferred example of the present invention, it can be further configured that: the bottom surface of the scraper is a slope inclined toward the inner wall of the cylinder.

By adopting the above technical solution, the bottom surface of the scraper forms a cutting end, which is attached to the inner wall, and it is easier to scrape off the residue on the inner wall of the cylinder.

In a preferred example of the present invention, it can be further configured that: the outer side wall of the cylinder is provided with an inwardly recessed groove, and the hot oil coil is fixed in the groove.

By adopting the above technical solution, after the hot oil coil is fixed in the groove, the inner wall of the groove is thinner, and the heat emitted by the hot oil coil is more likely to heat up the inner wall of the cylinder, so that the adherence solidifies on the inner wall of the cylinder The asphalt residue melts better.

In a preferred example of the present invention, it can be further configured that: the outer wall of the cylinder is detachably connected with a casing covering the groove.

By adopting the above technical solution, since the hot oil coil in the groove is dissipating heat, the casing is arranged to wrap the hot oil coil in the side wall of the cylinder to reduce heat dissipation and achieve a certain thermal insulation effect.

In a preferred example of the present invention, it can be further configured as follows: the top of the cylinder is provided with a hose for introducing the cleaning agent, and the hose is connected with several discharge pipes, and the discharge pipes are close to the side wall of the cylinder.

By adopting the above technical solution, only relying on the scraping of the scraper, the cleaning effect of the asphalt residue is limited. Therefore, when cleaning, a cleaning agent is added to remove the asphalt residue adhered to the inner wall of the cylinder more cleanly.

In a preferred example of the present invention, a fixing block is fixed on the top of the cylinder, the hose and the discharge pipe are arranged in the fixing block, and the discharge pipe communicates with the bottom surface of the fixing block.

By adopting the above technical solution, the fixed block supports the hose, and when the scraper slides to the top of the cylinder, it abuts against the bottom surface of the fixed block, preventing the scraper and the slider from sliding out of the cylinder.

To sum up, the present utility model includes at least one of the following beneficial technical effects:

1. When cleaning the cylinder body, the hot oil coil heats the side wall of the cylinder body, and the asphalt attached to the inner wall of the cylinder softens, and the scraper scrapes the residual asphalt on the inner wall of the cylinder towards the discharge port. , clean the residual asphalt out of the cylinder;

2. The hot oil coil is fixed in the groove, and the heat emitted by the hot oil coil is easier to heat up the inner wall of the cylinder, so that the asphalt residue adhered and solidified on the inner wall of the cylinder has a better melting effect;

3. Add cleaning agent to remove the bitumen residues adhering to the inner wall of the cylinder more cleanly.
