Description
Technical Field
The invention relates to the field of engineering equipment, in particular to a loader for mixed loading of emulsion explosives.
Background
The emulsion explosive is a water-in-oil emulsion explosive which is formed by uniformly dispersing microdroplets of an oxidant salt aqueous solution in an oil phase continuous medium containing porous substances such as dispersed bubbles or hollow glass beads and the like under the action of an emulsifier. The emulsion explosive has high density, high explosion speed and good water resistance, is often used for open-pit mining or rock blasting, and is prepared by drilling holes (forming blastholes) on the surface of rock, and then filling the emulsion explosive into the blastholes and detonating.
In the prior art, emulsion explosives are applied in two ways: 1. the finished emulsion explosive is packaged into a round bar shape, and a user directly fills the round bar shape into a blast hole for use; 2. a user uses a mixing vehicle to mix and load emulsion explosives (mainly mixing an emulsion matrix and an additive) on the construction site and then fills the emulsion explosives into blastholes for use. The mixed emulsion explosive is a semi-finished product before use, so that the safety performance is better; and the mixed emulsion explosive is more compact in blast hole filling and has wider application.
The process of filling the mixed emulsion explosive into the blast hole is from bottom to top: a discharge pipe of emulsion explosive mixed loading equipment (generally a mixed loading vehicle) is extended into the bottom of a blast hole, then the emulsion explosive is discharged from the discharge pipe and is filled in the blast hole from bottom to top, and accumulated water and air in the blast hole can be discharged to the maximum extent by the filling mode. However, the filling means of the emulsion explosive still has the defects that: 1. the pipe opening of the discharge pipe is always positioned at the bottommost part of the blast hole, the colloidal emulsion explosive is pushed upwards from the bottommost part of the blast hole and overturns, and the emulsion explosive scrapes the inner wall of the blast hole in the process, so that impurities such as stones and sand grains which are easy to wrap the inner wall of the blast hole are mixed into the emulsion explosive; 2. after the emulsion explosive is filled in the blast hole, workers need to extract the discharge pipe from the full emulsion explosive, the emulsion explosive in the blast hole is stirred again, and more impurities such as stones, sand grains and the like on the inner wall of the blast hole are wrapped and mixed into the emulsion explosive; the explosion effect of the emulsion explosive is influenced; 3. in the process of drawing the discharging pipe out by workers, the discharging pipe is easy to rub with the inner wall of the blasthole and the opening of the blasthole, impurities such as stones and sand grains are further mixed into the emulsion explosive, and meanwhile, the abrasion of the discharging pipe is accelerated.
Disclosure of Invention
The invention aims to solve the technical problem of providing a loader for mixing emulsion explosives, which avoids a discharge pipe of emulsion explosive mixing equipment from entering a blast hole, reduces the stirring and the billowing of the emulsion explosives in the blast hole and furthest ensures the purity of the emulsion explosives in the blast hole.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: a loader for mixing and loading emulsion explosives comprises a main bracket, a hard pipeline and a floating ball;

when the explosive is used, the bottom opening of the hard pipeline extends into the bottom of a blast hole, colloidal emulsion explosive is continuously discharged from the bottom opening of the hard pipeline, and the emulsion explosive bearing floating ball and the hard pipeline synchronously ascend; this means that the bottom opening of the hard pipeline is raised continuously to avoid the emulsion explosive from billowing in the blast hole. After the emulsion explosive in the big gun eye is filled up, the end opening of hard pipeline also arrives big gun eye oral area basically, compares in traditional emulsion explosive filling mode, does not have the process of taking out the discharging pipe from the big gun eye bottom, avoids stirring the emulsion explosive in the big gun eye.
Furthermore, the filling device also comprises an auxiliary support, the auxiliary support is positioned on the concave structure, a second unthreaded hole is formed in the auxiliary support, the second unthreaded hole is concentric with the first unthreaded hole, and the hard pipeline is inserted into the first unthreaded hole and the second unthreaded hole; the first unthreaded hole and the second unthreaded hole cooperate to ensure that the hard pipeline is vertical all the time.
Furthermore, the top of the hard pipeline is provided with threads and is provided with a limit nut, and the limit nut is used for controlling the specific height of the hard pipeline in the blasthole and ensuring that the bottom opening of the hard pipeline is slightly higher than the bottom of the blasthole.
Furthermore, the hard pipeline is made of plastics.
Furthermore, a circle of air bag is arranged on the outer ring of the concave structure; when the loader is used, the concave structure is embedded into the blasthole, and the air bag is filled between the concave structure and the inner wall of the blasthole after being expanded, so that the whole loader is fixed.
Furthermore, the inflation inlet of the air bag is provided with a one-way valve, and the exhaust port of the air bag is provided with a pressure release valve.
Has the advantages that: (1) according to the loader, the floating ball is arranged on the hard pipeline, so that the hard pipeline continuously rises along with the loading of the emulsion explosive in the blasthole, the bottom opening of the hard pipeline is always in a proper position as the outlet of the emulsion explosive, the emulsion explosive is prevented from being squeezed and turned over, the friction of the emulsion explosive on the inner wall of the blasthole is reduced, and impurities such as stones and sand grains are prevented from being wrapped and clamped into the emulsion explosive; (2) according to the loader, the hard pipeline of the loader continuously rises along with the loading of the emulsion explosive, and the hard pipeline or the discharge pipe does not need to be drawn out after the blast hole is filled, so that the emulsion explosive in the blast hole is prevented from being stirred; (3) in the use process of the loader, the hard pipeline and the discharge pipe are not in contact with the inner wall of the blast hole, so that the hard pipeline and the discharge pipe are prevented from being abraded.
