Description

Technical Field

[0001] The utility model relates to the field related to explosive processing, in particular to a pumping device for producing emulsion explosives. Background Art

[0002] The on-site mixing technology of emulsion explosives refers to the loading equipment loading the semi-finished emulsion matrix and additives of emulsion explosives produced by the ground station into the blasting operation site, and realizing the long-distance transportation of the emulsion matrix in the drug delivery pipe through the pumping and metering system. The emulsion matrix and additives are mixed in the mixer at the end of the drug delivery pipe and then enter the blasthole. After a certain period of chemical reaction, emulsion explosives are formed in the blasthole.

[0003] A Chinese patent document with publication number CN217410649U discloses an emulsion explosive pumping device, which can protect the drug delivery pipeline by a reinforcement unit arranged on the outer surface of the drug delivery pipeline. The buffer component 1 and the buffer component 2 inside the reinforcement unit have the function of improving the bearing force. The first and second buffer rods connected to the inner sides of the positioning ring rod 1 and the positioning ring rod 2 can absorb and transmit the vibration force, effectively improving the buffering force. Furthermore, the combined shock-absorbing spring sheet has a shock-absorbing effect, which can further effectively avoid the drug delivery pipe inside the pipeline from vibrating.

[0004] However, the device adopts a single material outlet setting method in the material distribution structure. Although this method has the advantages of low installation and replacement costs, the structure does not have the performance of distributing materials to multiple groups of storage containers at the same time, and the storage containers need to be filled in sequence, which leads to low production efficiency.
