Description
Technical Field
The invention belongs to the technical field of explosive and powder preparation, and particularly relates to a movable casting pot for slurry explosive and powder.
Background
Slurry explosives and powders such as PBX explosives, casting propellants, composite propellants and the like are widely applied in the explosive and powder industry, but the process is complex, the participation degree of personnel is high, kneading pots, transfer pots and casting pots with various functions are required to be equipped, and the slurry explosives and powders are required to be transferred among workshops for multiple times, so that explosive and powder slurries are required to be poured back and forth among the pots for turnover, personnel participates in the turnover process in the whole process, the residual powder slurries at the bottom of the pots are required to be shoveled out manually although the machine equipment is assisted, the labor intensity is high, the personal injury of the personnel is threatened, and the face-to-face operation danger of the personnel and the powder slurries is extremely high; the phenomena of residue or spilling and the like are difficult to avoid in the process of pouring, which causes waste or dangerous accidents. Therefore, a movable casting pot which integrates functions of kneading, transferring and casting is required to be developed, so that the phenomenon that gunpowder and explosive slurry are poured back and forth between pot bodies is avoided, and personnel participation or safety risks possibly existing in the pouring process are avoided.
The casting process commonly used in the current explosive and powder industry is to knead a kneading pot, if the turnover distance is short, the kneading pot is moved to a casting room, the slurry is poured into a casting pot, and then the casting pot is used for casting; if the turnover distance is long, then need add the transfer pot with the medicine thick liquid of kneading in the pot, shift the medicine thick liquid to the casting room by the transfer pot, pour into the casting pot by the transfer pot again and cast, the cycle of transportation is complicated, needs the manual work to constantly scrape the material and clear up when empting, and personnel participation degree is high, and intensity of labour is big, and the operation is very big to personnel's bodily injury under high temperature simultaneously to there is very high safety risk. The mode of hoisting and dumping the transfer pot and the casting pot is adopted in the civil industry at present, so that the slurry in the pot cannot be completely dumped, the casting quantity cannot be accurately controlled, the temperature of the pot cannot be controlled, and the method is not suitable for the casting process in the explosive industry. Therefore, a casting pot which can automatically control the start and stop of casting and perform quantitative casting is required to be developed, has the function of convenient transportation, and can be butted with a circulating water path.
The utility model CN209407404U discloses a casting mold casting pan, which is characterized in that the casting pan is hoisted and transferred through a guide rail, and the pulley on the guide rail and the brackets arranged at the two ends of the casting pan are driven by an electric hoist to ensure that the casting pan is inclined for casting, thereby realizing the automatic dumping of the casting pan; the utility model CN204276883U discloses a mould casting boiler for copper carving casting, which is manually inclined by a wheel disc and a lifting rod for casting; the invention patent CN110440644A discloses a casting pot for filling fusion-cast explosive, which accurately controls the casting amount through a rubber tube valve, and the pot body is provided with a heat-insulating water jacket connected with a circulating water path; the invention patent CN105889555A discloses a normally closed pipe clamp valve for liquid energetic materials, which realizes the opening of a pipeline by clamping a rubber pipe through a cylinder, and enables the pipeline to be in a normally closed state by adding a spring in the cylinder. The third and fourth of the above patents are the closest to the present invention.
However, the devices of patent CN110440644A and patent CN105889555A have the following disadvantages: (1) the design of devices such as transfer or transfer is not considered, and hoisting and positioning cannot be carried out during transfer; (2) the butt joint of the circulating water paths needs to be carried out manually, and the personnel need to butt joint the water paths after the water paths are transported in place each time and can leave the site; (3) normally closed and normally opened of the rubber tube valve are carried out through the air cylinder, so that the pot body needs to carry the large air cylinder in the transportation process, the space is occupied, and an air source pipeline cannot be processed. The above disadvantages cause problems that the casting pan can only be used for casting at a fixed position, and the transfer pan or the kneading pan is still needed to transfer the slurry and pour the slurry into the rear of the casting pan for casting. Therefore, a casting pot for slurry explosives and powders, which has a simple structure and strong reliability and is movable, needs to be developed.
