Abstract
Description
Technical Field
[0001] The utility model relates to the field of equipment for aluminum processing, in particular to an aluminum smelting waste residue treatment device. Background Art
[0002] Since the first smelting or melting of metallic aluminum, aluminum slag has been an inevitable by-product. It is a mixture of aluminum metal and aluminum oxide containing a small amount of other components. Aluminum slag is not waste, but a by-product of important value. Thermodynamics shows that as long as there is oxygen near the exposed aluminum surface, aluminum will oxidize to produce aluminum oxides of various components. In most aluminum slags, there is still enough recoverable metallic aluminum remaining. If it is simply processed and sold, it will not only cause great waste, but also pollute the environment. Therefore, it is very important to maximize the recovery of metallic aluminum in aluminum slag.
[0003] At present, the treatment of aluminum ash in many factories is semi-mechanized operation. The so-called semi-mechanized treatment is to use a traditional down-pressing and stirring treatment device to treat hot aluminum ash. The single-time treatment capacity of hot aluminum ash is 200 - 300 kg. After the hot aluminum ash is treated, it is transported by a forklift to a cooling platform for manual spreading of the ash to cool down. After the ash is cooled, it is packed by manual work tools for sale. Our factory also treats it in this way. The problem with such semi-mechanized operation is that the cooling and screening of aluminum particles for aluminum recovery are not thorough. The current recovery rate is 25 - 30%, which has a large gap compared with the industry standard of 35 - 40%. The goal of full recovery has not been achieved, which is not conducive to cost control. Secondly, manual spreading of the ash causes extremely poor on-site environment and high labor intensity, which cannot meet the requirements of Class A enterprises and poses environmental protection risks. Content of the Utility Model
[0004] The purpose of the utility model is to provide an aluminum smelting waste residue treatment device to solve the problems of incomplete aluminum recovery after the treatment of existing aluminum smelting waste residue and poor environment of manual ash spreading.
[0005] To solve the above technical problems, the utility model adopts the following technical solutions:
[0006] An aluminum smelting waste residue treatment device includes a ash frying machine, a cold ash machine and a ash screening machine. The slag discharge port of the ash frying machine is connected to the feed inlet of the cold ash machine through a guide plate, and the discharge port of the cold ash machine is connected to the feed inlet of the ash screening machine through a screw feeding mechanism.
[0007] The cold ash machine and the ash screening machine are introduced. The hot aluminum slag obtained after frying the ash is cooled by the cold ash machine, and then mechanized ash screening treatment is carried out. In this way, the aluminum recovery rate is high, and manual ash spreading is not adopted, with higher efficiency and better environment in the workshop.
[0008] As a further preference of the present utility model, the cold ash machine includes a cold ash cylinder, a rotating support base, a rotating motor, and a spray cooling and heat exchange mechanism. The cold ash cylinder is rollingly mounted on the top of the rotating support base. The output gear of the rotating motor meshes with a ring gear arranged outside the cold ash cylinder. The spray cooling and heat exchange mechanism is arranged above the cold ash cylinder.
[0009] Through the cooperation of the rotating motor, the output gear and the ring gear, the cold ash cylinder can be well driven to rotate. The spray cooling and heat exchange mechanism can continuously spray, so that the temperature of the cold ash cylinder body will not be too high.
[0010] As a further preference of the present utility model, the rotating support base includes a heat insulation base body and support rollers. The support rollers include a front support roller and a rear support roller. The front support roller is arranged at the bottom of the feeding end of the cold ash cylinder, and the rear support roller is arranged at the bottom of the discharging end of the cold ash cylinder.
[0011] As a further preference of the present utility model, a roller coolant nozzle is arranged below the front support roller.
[0012] Since the feeding end of the cold ash cylinder is the place where the hot aluminum slag first enters, the temperature of the cylinder body at this place is relatively high, and the front support roller is prone to deformation at high temperature, affecting its service life. In order to keep the temperature of the front support roller from being too high, a coolant nozzle is arranged below the front support roller. The coolant continuously sprayed by the coolant nozzle can effectively cool the front support roller, so that it always maintains a relatively low temperature state, and it is not easy to have problems such as a decrease in service life caused by deformation due to too high temperature.
[0013] As a further preference of the present utility model, hydraulic lifting support mechanisms are arranged at both the front and rear of the bottom surface of the cold ash cylinder.
[0014] When it is necessary to replace the front support roller and the rear support roller, the cold ash cylinder can be lifted through the hydraulic lifting support mechanism, which is convenient for replacing the support rollers.
[0015] As a further preference of the present utility model, the spray cooling and heat exchange mechanism includes a cold ash cylinder cooling spray pipe. The cold ash cylinder cooling spray pipe includes an upper spray pipe and a lower spray pipe. The upper spray pipe is evenly arranged above the cold ash cylinder, and the lower spray pipe is arranged below the first half of the cold ash cylinder. Cold ash cylinder cooling spray nozzles are evenly arranged at the bottom of the upper spray pipe and the top of the lower spray pipe.
[0016] The temperature of the first half of the cold ash cylinder is too high. Therefore, not only the upper spray pipe is needed for cooling, but also the lower spray pipe is needed to cooperate, so that a better cooling effect can be achieved.
[0017] As a further preference of the present utility model, it further includes a dust removal system disposed in the ash frying room.
[0018] It can perform an inhalation treatment on the dust and soot generated during the production process. The dust removal system mainly consists of a dust suction port, a dust suction pipe, and a dust suction fan.
[0019] Compared with the prior art, the present utility model can achieve at least one of the following beneficial effects:
[0020] 1. The cold ash machine and the ash screening machine are introduced. The hot aluminum slag obtained after ash frying is cooled by the cold ash machine, and then mechanical ash screening treatment is carried out. In this way, the aluminum recovery rate is high, and manual ash spreading is not adopted, so the efficiency is higher and the environment in the workshop is better.
[0021] 2. Through the cooperation of the rotating motor, the output gear and the annular tooth row, the cold ash cylinder can be well driven to rotate. The spray cooling and heat exchange mechanism can continuously spray, so that the temperature of the cold ash cylinder body will not be too high.
[0022] 3. Since the feeding end of the cold ash cylinder is the place where the hot aluminum slag first enters, the temperature of the cylinder body at this place is relatively high, and the front support roller is prone to deformation at high temperature, which affects its service life. In order to keep the temperature of the front support roller from being too high, a coolant nozzle is arranged below the front support roller. The coolant continuously sprayed by the coolant nozzle can effectively cool the front support roller, so that it always maintains a relatively low temperature state, and thus it is not easy to have problems such as a decrease in service life caused by deformation due to too high temperature.
[0023] 4. When the front support roller and the rear support roller need to be replaced, the cold ash cylinder can be lifted by the hydraulic lifting support mechanism, which is convenient for replacing the support rollers.
[0024] 5. The temperature of the first half of the cold ash cylinder is too high. Therefore, not only the upper spray pipe is needed for cooling, but also the lower spray pipe is required to cooperate, so that a better cooling effect can be achieved.
[0025] 6. It can perform an inhalation treatment on the dust and soot generated during the production process. The dust removal system mainly consists of a dust suction port, a dust suction pipe, and a dust suction fan. BRIEF DESCRIPTION OF THE DRAWINGS
