Embodiment 1

[0026] This embodiment provides a filling slurry nozzle, such as figure 1 and figure 2 As shown, it includes a first nozzle 4, a sleeve 2, a second nozzle 3, and a connecting pipe 1. One end of the sleeve 2 is detachably connected to the first nozzle 4, and the other end is detachably connected to the connecting pipe 1. The second nozzle 3 is installed in casing 2.

[0027] Specifically, the first nozzle 4 is used as a nozzle body, which is made of metal material, such as stainless steel; one end of the first nozzle 4 is an inlet end, and the other end is an outlet end, and the inlet end and the outlet end are connected through a channel.

[0028] Further, the inside of the first nozzle 4 is a variable-diameter channel, the cross-section of the inlet end is circular, and the outlet end is a strip-shaped gap (the cross-section is rectangular); the inlet end and the outlet end are connected through the variable-diameter channel to form a flat structure .

[0029] In this emb...

Embodiment 2

[0043] This embodiment provides a slurry-making system for filling a sand bin, including the slurry-making nozzle described in Embodiment 1.

Abstract

The invention discloses a filling slurry making nozzle and a filling sand silo slurry making system, and belongs to the technical field of mine filling. The technical scheme is that the filling slurry making nozzle comprises a first nozzle, a sleeve and a second nozzle, wherein the inlet end of the first nozzle is connected with the sleeve, the inlet end forms an outlet end with a strip-shaped section through a reducing channel, the outer side of the first nozzle is coated with an elastic wear-resistant layer, the wear-resistant layer extends outwards corresponding to the outlet end to form an extension section so as to automatically close or open the outlet end, and the second nozzle matched with the first nozzle in shape is fixed in the sleeve. According to the filling slurry making nozzle, the problems that according to a traditional nozzle, mortar is likely to flow back, and spraying holes are likely to be blocked are solved, and the service life of the nozzle is prolonged on the basis that the mortar making effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mine filling, in particular to a filling slurry making nozzle and a sand bin filling slurry making system. Background technique [0002] In the filling process, most of them need to use vertical sand bins or thickeners as the dense dehydration and storage of tailing mortar. The stored mortar will deposit in the bin body, and hardening often occurs. Before sand filling, it is necessary to check the bin The hardened mortar in the body is activated, and the mainstream pulping process is Fengshui linkage pulping process, and the Fengshui activated mortar is realized by installing nozzles in the inner ring pipeline of the warehouse. [0003] There are mainly two types of slurry nozzles currently in use. The first type of slurry nozzle is made of holes on the side wall of the steel pipe, and the surface is backstopped by an elastic sleeve or the deformation of this type of nozzle. This nozzle is made of elastic...
