This utility model provides a sand fracturing device for coal mine gas drainage wells, including a mixing component, a storage component, and a fracturing pump. The mixing component, storage component, and fracturing pump are respectively mounted on a support, with the fracturing pump located below the mixing component, which is located below the storage component. The mixing component includes a shell and a stirring unit. The stirring unit is mounted on the shell, with one end of the stirring unit located inside the shell. The shell has a first feed inlet and a second feed inlet, which are arranged opposite to each other on the outer periphery of the shell. The first and second feed inlets are respectively used to connect to the storage component. The lower end of the shell has a first discharge outlet. This sand fracturing device for coal mine gas drainage wells replaces the traditional sand fracturing method of feeding sand by its own weight, solving the problem of sand clogging the conveying pipeline during the traditional sand fracturing process, thus improving work efficiency and safety.

This utility model discloses a dispensing device, comprising: an A-type glue container and a B-type glue container, wherein the A-type glue container holds A-type glue and the B-type glue container holds B-type glue; and a mixing component, wherein the A-type glue container is connected to the mixing component via a first pipeline, and the B-type glue container is connected to the mixing component via a second pipeline, and the mixing component is used to mix the A-type glue and the B-type glue; wherein the first pipeline is equipped with a first flow meter, and the second pipeline is equipped with a second flow meter. The dispensing device of this utility model, by setting a first flow meter in the first pipeline for conveying A-type glue and a second flow meter in the second pipeline for conveying B-type glue, can precisely control the amount of A-type glue and B-type glue to ensure the mixing ratio of A-type glue and B-type glue, thereby ensuring the sealing effect of the junction box, improving the waterproofness of the junction box, avoiding rework problems, improving production efficiency, ensuring the appearance quality of the junction box, having a simple structure, reducing installation costs, better performance, and a wider range of applications.
