Description

A slurry discharge device for mine underground mixing station

technical field

The utility model relates to a slurry discharge device. In particular, the utility model relates to a slurry discharge device for a mixing station in a mine.

Background technique

As the mining path of metal mines extends to deeper parts underground, the safety production requirements for shotcrete support and full-section support gradually increase. Due to the high transportation cost and long transportation time of commercial spraying slurry to the underground, it is difficult to meet the needs of underground operations. Therefore, many large metal mines have built spraying material mixing stations in the deep underground, and use spraying material transfer vehicles to transport them to the working surface, and workers at the working surface use spraying trolleys to carry out full-section spraying support operations.

Due to the harsh underground working environment, the shotcrete material provided by the shotcrete mixing station is often mixed with large stone aggregates or sundries, and these large stone aggregates or sundries need to be filtered out when the slurry is discharged. However, the discharge mechanism of the existing spraying material mixing station lacks a filtering mechanism, so it is prone to blockage or even damage to the spraying equipment.

On the other hand, the discharge port of the discharge mechanism of the existing spraying material mixing station is usually not in the same size as the slurry conveyor belt. The operation between the discharge port and the slurry conveyor belt is cumbersome and easy to cause splashing and leakage due to loose connection.

In the third aspect, due to the lack of a cleaning door in the discharge bin of the discharge mechanism of the existing spraying material mixing station, it is difficult to clean the inside of the discharging bin, and the phenomenon of slurry hardening is relatively serious, which affects the operating efficiency of the spraying material mixing station.

Utility model content

The technical problem to be solved by the utility model is to provide a slurry discharge device for the underground mixing station of a mine, firstly, to realize the filtration and removal of large particles of material discharged from the mixing station; secondly, to set the discharge port and the slurry The butt joint of the conveyor belt cooperates with the special mechanism to achieve tight butt joint; thirdly, solve the internal cleaning problem of the discharge bin.

The technical scheme of the utility model is as follows:

A discharging device for grouting material in a mixing station in a mine, comprising a quadrangular table-shaped discharge hopper whose upper port size is larger than that of the lower port and whose upper and lower ends are both open, a rectangular screen is installed inside the discharge hopper, and the rectangular screen is The four sides of the net are in one-to-one contact with the four side walls of the discharge hopper and are fixedly connected; one of the side walls of the discharge hopper is provided with a cleaning door that can be opened and closed from the outside; the lower part of the cleaning door The edge is located on the upper side of the rectangular screen.

Preferably, the cleaning door is connected to the side wall plate of the discharge hopper through fastening bolts.

Preferably, a door handle is fixedly installed on the outside of the cleaning door.

Preferably, the upper port of the discharge hopper is fixedly installed with a mounting plate for connecting with the slurry discharge port of the mixing station.

Preferably, a bottom plate is fixedly installed at the lower port of the discharge hopper; a circular through hole is opened on the bottom plate; a plug-in flange is installed at the circular through hole.

Compared with prior art, the positive effect of the utility model is:

First, the cleaning door of the utility model and the side plate of the discharge hopper are fastened by bolts, which is convenient to open and timely clean up the sprayed slurry inside the discharge hopper and the large-grained aggregate debris on the upper side of the screen, and realizes the large-particle discharge of the mixing station. Material filtration and removal, and convenient cleaning of the inside of the discharge hopper can be achieved, which can effectively avoid blocking the spraying equipment.

Second, the cleaning door and the side plate of the discharge hopper of the utility model are both inclined up and down, which can buffer the sprayed slurry falling from the mixing station and prevent splashing.

Third, when discharging the grouting material, quickly connect the conveyor belt on the conveyor belt of the grouting material transfer vehicle to the discharge port of the discharge mechanism of the mixing station through the plug-in flange, which is not only convenient to operate, but also has good sealing performance. It effectively solves the problem of sprayed grout falling near the discharge port.
