Emulsion explosive waste treatment device

Abstract

The invention relates to a treatment device for waste emulsion explosives, which includes a cross bar, a bracket, a discharge pipe with a valve, a driver, and a piston, and also includes an open material cylinder, an outer cylinder liner, a motor, and a stirring paddle; There is an outer cylinder liner to form a sandwich, and the upper and lower parts of the outer cylinder liner are respectively provided with a liquid inlet and a liquid outlet that are directly connected to the interlayer, which can be heated or cooled by external hot or cold water in and out of the interlayer; the upper part of the bracket is symmetrically provided with a cross bar support A motor with a stirring paddle and a driver with a piston. The lower part of the rotating bracket is symmetrically equipped with an open material cylinder with an interlayer. The agitating paddle connected to the motor and the piston connected to the driver can respectively extend into the lower part and respectively have a corresponding interlayer. Stirring or extruding is carried out in the open material tank; the bottom of the open material tank with interlayer is equipped with a valve discharge pipe. It has the ability to melt, emulsify, sensitize and regenerate waste medicine in an integrated manner. It has a simple and practical structure, strong processing capacity and low cost. Material regeneration applications.

Description

1. Technical field [0001] The invention relates to a treatment device for waste emulsion explosives, which is suitable for use in civil explosive enterprises. 2. Technical background [0002] During the production, storage and use of emulsion explosives, waste emulsion explosives will appear due to problems such as charging to the packaging process machinery and facilities or due to the failure of the inkjet printer in the production line that needs to be coded. The industry stipulates for waste emulsion explosives: (1) Products with insufficient weight of individual drug rolls, unclear labels or damaged packaging films are Class I unqualified products; (2) do not meet the performance indicators in the product inspection standards and return (3) When the process equipment debugging or production is abnormal, the unemulsified water-oil phase mixture produced at the outlet of the emulsifier and the waste generated by cleaning the emulsifier when the emulsifier is shut down bel...

AI Technical Summary

Problems solved by technology

At present, waste drug treatment generally involves adding a small amount of waste drug to new emulsion explosives, and then vigorously stirring to fully mix the waste drug and the new drug. However, during the mixing process, the temperature of the waste drug is often low and the mixing is uneven. The quality of the emulsion explosives produced by mixing is poor, and the stability during the storage period is also poor, and even stratification, demulsification, explosion rejection and half-explosion appear. There are also production safety hazards

Now many companies think that the quality of the reworked explosives is not up to standard, which will affect the reputation of the company. Out of helplessness, they have to burn and destroy the waste explosives.

[0003] In order to solve the above problems, Chinese patent CN203316072U discloses a "high temperature sensitized emulsification pharmaceutical production line waste drug treatment device", which is composed of a screw pump, a flange, a main discharge pipe and a hopper with a tubular heating isolation net inside. The negative pressure of the screw pump is used to filter and fill the waste medicine, which belongs to the device that the industry has clearly prohibited the online rework of unqualified products and waste materials, and has the following shortcomings: First, it can only be used for Class I unqualified products. However, Class II substandard products and Class I waste cannot be processed; secondly, the waste drug contains sensitized bubbles, which will escape due to heating. Third, although the waste drug is heated, the waste drug is a colloidal viscous substance, and the negative pressure of the screw pump is not enough to inhale the waste drug for filtration, and the treatment efficiency is not high

[0004] Chinese patent CN203295393U also discloses a "waste drug recovery device", which consists of a support, a driver, a material cylinder, a piston, a drug discharge pipe and a drug suction pipe, a drug suction check valve, a drug discharge check valve, a sealed Composed of upper and lower tanks and controllers, the use of sealed upper and lower tanks with pistons for waste drug recovery also has the following disadvantages: First, it can only deal with Class I unqualified products with damaged packaging, while for Class II unqualified products Second, the processing efficiency is limited and the energy consumption is high; the third is the complex structure and poor safety
