Automatic production line for nickel hydrazine nitrate primary explosive

Abstract

The invention provides an automatic production line for nickel hydrazine nitrate primary explosive. The production line comprises a nickel nitrate solution preparation system, a solution storage and metering system, a combination reaction measurement and control system, a tray separation system, a washing, suction filtration and dehydration system, a conveying system, an online water bath vacuum drying system, a screening and boxing system for quantitatively distributing primary explosive, an explosive tray cleaning and transferring system and a control system for controlling all the systems in the production line to work and operate. The nickel nitrate solution preparation system is used for preparing a nickel nitrate solution and conveying the nickel nitrate solution to the solution storage and metering system, and the chemical combination reaction measurement and control system is used for heating in a water bath and measuring and controlling the temperature of a chemical combination reaction. According to the invention, the automatic tray washing system of the initiating explosive trays is added to the production line, a low-temperature low-vacuum water bath drying process is adopted for the initiating explosive trays, empty trays are transferred through an AGV, mechanization on the whole line is achieved, the number of workers is reduced to the minimum, and continuous andautomatic production of the nickel hydrazine nitrate initiating explosive is achieved.

Description

technical field [0001] The invention relates to the technical field of primary explosive production technology, in particular to an automatic production line of nickel hydrazine nitrate primary explosive. Background technique [0002] With the continuous improvement of the level of science and technology in our country, the varieties of primers, the types and demands of military explosives and blasting equipment are also increasing day by day, and it is urgent to solve the technical problems of mass and safe production of primers. Due to the high risk of primary explosives, it is extremely difficult to adopt continuous and automated production lines and technological processes. General-purpose production devices and equipment cannot meet the requirements for the use of primary explosives for fire and explosion protection, and special equipment and devices have not been developed as they should 1. Some process facilities and equipment have poor reliability, so the continuous a...

Problems solved by technology

Due to the high risk of primary explosives, it is extremely difficult to adopt continuous and automated production lines and technological processes. General-purpose production devices and equipment cannot meet the requirements for the use of primary explosives for fire and explosion protection, and special equipment and devices have not been developed as they should , Some process facilities and equipment have poor reliability, so the continuous automatic production technology of primary explosives has not been well resolved, forming a bottleneck restricting the technological progress of my country's military and civilian explosives.

[0003] Many priming powder automatic production lines have been formed in the prior art, but there are still several deficiencies in the production line: (1) the priming powder is carried out by manual operation to carry out vacuum drying. The sub-packaging tray is sent into the vacuum dryer by the operator, and then vacuum dried. After the vacuum drying is completed, the operator takes out the sub-packaging tray of the priming charge and sends it to the next process

But, because the sensitivity of priming charge is very strong, the risk of the priming charge after drying is higher, therefore, it is very dangerous to carry the priming charge subpackage dish that priming charge is housed manually; (2) priming charge empty charge The method of cleaning the disks is still manual cleaning. Manual cleaning is not only low in efficiency and high in intensity, but also the cleanliness of the cleaning is subject to the subjective influence of the workers, and the cleanliness cannot be guaranteed, which greatly increases the production cost of the enterprise. The attached residual medicine will cause potential harm to the operator; (3) The transportation of empty medicine trays is still done manually, and the closed-loop production of the production line cannot be achieved; (4) All links in the entire production line are intermittent production , the inability of continuous automatic production leads to low production efficiency of the whole line, and the design capacity of the equipment cannot meet the production needs of large quantities
