Description
Technical Field
The invention relates to equipment for drying mineral powder by using waste heat of a rotary kiln, in particular to a waste heat drying device of the rotary kiln.
Background
The rotary kiln is used as a device for roasting mineral powder, the internal temperature of the rotary kiln is very high, and although various heat preservation and insulation measures are adopted on the inner wall of the rotary kiln, the surface of the rotary kiln can still reach a certain temperature, so that a large amount of heat energy is directly dissipated into the air, and the energy is wasted. Mineral powder placed in the air for a long time is affected by moisture and affected by the moisture, the roasting time of the mineral powder is directly affected by the affected mineral powder, and the roasting efficiency of the mineral powder is low.
Disclosure of Invention
The invention aims to solve the technical problems and provides a rotary kiln waste heat drying device which can dry mineral powder by heat energy dissipated to the air of a rotary kiln, so that energy waste is reduced, the subsequent roasting time of the dried mineral powder can be shortened, and the roasting efficiency of the mineral powder is improved.
The technical solution of the invention is as follows:
the rotary kiln waste heat drying device is characterized in that: the rotary kiln material distributing device comprises a platform which is arranged above a rotary kiln in a straddling mode, a material distributing vehicle which moves back and forth and is arranged on the platform, a liftable scraper plate is arranged at the bottom of the material distributing vehicle, a crane which moves left and right and is arranged above the front end of the platform, and a material discharging opening is formed in the rear end of the platform.
More preferably, the distributing vehicle is composed of a vehicle body, a hopper mounted on the vehicle body, crushing rollers mounted in the hopper and arranged in the front and back direction, and a material leveling roller mounted in the bottom of the vehicle body and arranged in the front and back direction.
Preferably, the scraper is rotatably mounted with the vehicle body through a rotating shaft, a motor for driving the rotating shaft to rotate is mounted at one end of the vehicle body, the scraper is controlled to rotate up and down through the motor, and then the lower end of the scraper is controlled to lift.
Further preferably, the scraper is positioned in front of the hopper, so that the mineral powder is completely scraped out of the platform and no residue is left.
Further preferably, guard plates are arranged on the periphery of the platform to prevent mineral powder from overflowing the platform.
Further preferably, a rail extending in the front-rear direction is mounted on the platform, and the cloth vehicle is mounted on the rail.
Further preferably, a screw feeder extending to one side is mounted on the platform below the discharge opening, and the screw feeder outputs the mineral powder scraped to the discharge opening to an external receiving vehicle.
The invention has the beneficial effects that:
1. because the platform is arranged above the rotary kiln in a straddling manner, the heat energy emitted by the rotary kiln to the air heats the platform, the heated platform dries the mineral powder spread on the platform, the energy waste is reduced, the subsequent roasting time of the dried mineral powder is shortened, and the roasting efficiency of the mineral powder is improved.
2. Because the distribution vehicle moving back and forth is arranged on the platform, the mineral powder can be uniformly distributed and paved on the platform, the mineral powder drying area is increased, and the mineral powder drying efficiency is improved.
3. Because the liftable scraper is arranged at the bottom of the distributing vehicle, the dried mineral powder can be pushed out of the platform, and the dried mineral powder is convenient to recover.

Detailed Description
As shown in fig. 1 and 2, the rotary kiln waste heat drying device includes a platform 1 straddling above the rotary kiln, a guard plate 2 is installed around the platform 1, a rail 3 extending in the front-rear direction is installed on the platform 1, a distributing vehicle 4 is installed on the rail 3, the distributing vehicle 4 is composed of a vehicle body 401, a hopper 402 installed on the vehicle body 401, crushing rollers 403 installed in the hopper 402 and arranged in the front-rear direction, a material leveling roller 404 installed at the bottom of the vehicle body 401 and arranged in the front-rear direction, and a lifting scraper 405 installed at the bottom of the vehicle body 401 and located in front of the hopper 402, the scraper 405 is rotatably installed with the vehicle body 401 through a rotating shaft, and a motor 406 driving the rotating shaft to rotate is installed at one end. A crane 5 which can move left and right is arranged above the front end of the platform 1, a discharge hole 6 is arranged at the rear end of the platform 1, and a screw feeder 7 which extends to one side is arranged on the platform 1 and is positioned at the lower part of the discharge hole 6.
The working principle of the invention is as follows:
firstly, a hanging bag containing mineral powder is lifted above a distribution vehicle 4 through a crane 5, the mineral powder in the hanging bag is loaded into the distribution vehicle 4, then the distribution vehicle 4 is started to move from front to back, in the movement process of the distribution vehicle 4, a crushing roller 403 crushes mineral powder agglomerates into powder, the mineral powder in a hopper 402 is scattered onto a platform 1 from front to back through the bottom of the hopper 402, meanwhile, a leveling roller 404 levels the mineral powder scattered onto the platform 1, then the platform 1 is heated by using the waste heat of a rotary kiln, and the heated platform 1 dries the mineral powder scattered onto the platform 1. After the mineral powder scattered on the platform 1 is dried, the distributing vehicle 4 is moved to the front end of the platform 1, the motor 406 is started to rotate the scraper plate 405, the scraper plate 405 is attached to the platform 1, then the distributing vehicle 4 is moved backwards in the forward direction, the mineral powder on the platform 1 is scraped to the discharge hole 6 at the rear end of the platform 1 through the scraper plate 405, and finally the mineral powder from the fruit stone to the discharge hole 6 is output to the external receiving vehicle through the screw feeder 7.
The above description is only exemplary of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
