Description

Technical Field

[0001] This utility model relates to the field of emulsion explosive production technology, specifically to an injection tube for an emulsion explosive loading machine. Background Technology

[0002] Emulsion explosives are a type of water-in-oil emulsion-like aqueous industrial explosive, in which microdroplets of an oxidant aqueous solution are suspended in a continuous phase medium containing dispersed bubbles, hollow glass microspheres or other porous materials, forming a water-in-oil emulsion-like aqueous industrial explosive. Currently, the JWL-Ⅲ type emulsion explosive production line of Shenzhen Jin Aobo Company is used.

[0003] The production line uses high-temperature static sensitization technology. The capacity of a single filling machine can reach 8-10 t / h. Due to long-term high-speed rotation, the pressure roller of the filling machine has worn the surface of the injection tube at the lower end of the pressure roller. During the film feeding and film adhesion process, problems such as film feeding deviation, uneven film adhesion, and film bursting occur, causing the production line to stop and producing a large number of unqualified semi-finished products. This increases the consumption of raw materials and labor rework costs. In the past, this problem could only be solved by replacing the entire injection tube, which resulted in high maintenance costs.

[0004] Therefore, a new injection tube for emulsion explosives charging machines is needed to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is: the purpose of this utility model is to provide an injection tube for an emulsion explosive charging machine, so as to solve the problem of high maintenance cost of the injection tube for the charging machine mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A charging tube for an emulsion explosives charging machine includes a forming tube with a positioning groove on the left side of the top end of the forming tube and a wear-resistant alloy block inside the positioning groove. The outer edge of the wear-resistant alloy block protrudes from the surface of the forming tube.

[0008] Furthermore, in the above-mentioned structure for the injection tube of the emulsion explosive loading machine, the wear-resistant alloy block is made of GH4169 alloy.

[0009] Furthermore, in the above-mentioned structure for the injection tube of the emulsion explosive loading machine, the depth of the positioning groove is 0.8-1.2mm.

[0010] Furthermore, in the above-mentioned structure of the injection tube for the emulsion explosive charging machine, the wear-resistant alloy block is welded to the positioning groove.

[0011] Furthermore, the above-mentioned injection pipe structure for the emulsion explosive loading machine also includes a mounting frame and a conveying pipe. A sleeve is fixed at the center of the left side of the mounting frame, and a conveying pipe is provided inside the sleeve. A forming pipe is fixed to the right side of the conveying pipe, and a plastic film forming device is fixedly connected to the outside of the conveying pipe.

[0012] Furthermore, in the above-mentioned structure for the injection tube of the emulsion explosive charging machine, the surface of the mounting bracket is provided with mounting holes.

[0013] The beneficial effects of this utility model are as follows: by setting a positioning groove and a wear-resistant alloy block, the worn part of the plastic film heat cover of the forming tube is reprocessed into a groove one millimeter deep to form a positioning groove, and a wear-resistant alloy block is welded into the positioning groove. The thickness of the wear-resistant alloy block is slightly higher than that of the plastic film heat cover. The wear-resistant alloy block is easy to replace after wear, and the forming tube can be reused, thus realizing the repair and use function of the drug filling machine's injection tube.
