Description

A coal gangue concrete experimental mixing device

Technical Field

The utility model belongs to the technical field of coal gangue, and in particular relates to a coal gangue concrete experimental mixing device.

Background technique

Coal gangue is a kind of rock that accompanies and coexists with coal during the formation of coal. It is solid waste generated during coal mining, cleaning and processing. In order to save resources, alkali activator materials are used to mix and improve coal gangue, eliminating the consumption of non-renewable resources such as cement, sand and gravel in concrete. It is an environmentally friendly green building material. When experimenting with improved coal gangue concrete, standard test blocks for testing mechanical properties are made according to the concrete test specifications.

A search of CN212096900U disclosed a coal gangue concrete experimental mixing device, comprising a mixing barrel, a conical block is arranged at the bottom end of the mixing barrel, a stirring shaft is arranged inside the mixing barrel, the top of the stirring shaft is connected to the main shaft of a motor fixed to the top of the mixing barrel through a support frame, a bent stirring rod located outside the conical block is arranged at the lower part of the stirring shaft, a plurality of discharge pipes connected to the mixing barrel are evenly arranged at the root of the outer side, and a plug plate for controlling the falling of the material is arranged on the discharge pipe. The device has a simple structure and is easy to operate. It saves time and effort in preparing coal gangue concrete sample blocks and greatly improves efficiency.

However, the inventors have discovered that this technical solution still has at least the following defects:

In the above device, after the cement and the coal gangue are evenly mixed, two people are required to hold the two sides of the ring frame and lift it up. The ring frame drives all the plug plates to move upward, so that all the discharge pipes are in a discharge state, and then the materials in the mixing barrel are discharged into each solidification barrel through the discharge pipe. This discharge method is more troublesome and increases the workload of the staff. Then, when the materials in each solidification barrel are filled, the ring frame is quickly lowered to make the plug plate close the discharge pipe, and then all the solidification barrels containing materials are placed together, and then new solidification barrels are placed in the grooves of each bottom plate for the next material collection. Multiple solidification barrels are required to collect the materials. After the collection is completed, the multiple solidification barrels are placed together. The number of discharge pipes for discharging and the number of solidification barrels for receiving materials are too large, which brings great inconvenience to the staff's material collection work.

In view of this, the present utility model is proposed.
