Technical Field
[0001] This utility model relates to the technical field of mortar mixing equipment, specifically to a mortar mixing equipment for EPS insulation boards that can perform secondary mixing. Background Technology
[0002] EPS insulation board (expandable polystyrene board) has advantages such as being lightweight, inexpensive, having low thermal conductivity, low water absorption, good electrical insulation properties, sound insulation, shock absorption, moisture resistance, and simple molding process. Therefore, it is widely used as a thermal insulation, sound insulation, and earthquake-resistant material in construction, shipbuilding, automobiles, trains, refrigeration, and freezing industries. When EPS insulation board is used as a building material, it can be directly mixed with mortar, which is poured onto the surface of the EPS insulation board or into its grooves.
[0003] Mortar is generally produced by mixing equipment. Most current mortar mixing equipment consists of a cylindrical body, and a spiral mixing blade is usually installed inside the cylinder. This mixing equipment can mix mortar, but the mortar is prone to clumps, which affects the quality of the mortar.

[0020] like Figure 3-4 As shown, the extension frame 4 includes a left crossbar 401, a right crossbar 402, a side crossbar 403, and a vertical frame 404. The left crossbar 401 is welded to the support frame 3, and the right crossbar 402 is welded to the vertical frame 404. The left crossbar 401 and the right crossbar 402 are connected by two side crossbars 403 to form a rectangular space. The mixing drum 2 is set in the rectangular space formed by the left crossbar 401, the right crossbar 402, and the two side crossbars 403.

In use, the raw materials are added into the main mixing drum 1 through the feed port via a screw conveyor. Water is added as needed. The first motor 5 is started. The first motor 5 drives the screw mixing blade 9 to rotate through the first main shaft 8, thereby realizing the first mixing of the mortar. Then, the first discharge valve 11 is opened, and some mortar flows into the dispersing mixing drum 2. At this time, the second motor 6 is started. The second motor 6 drives the sawtooth agitator 14 to rotate through the second main shaft 13, and the mortar is mixed a second time. Then, the second discharge valve 16 is opened to realize the discharge. This utility model has a reasonable structure. A dispersing and mixing drum 2 is set on one side of the support frame 3 through the extension frame 4.

When pouring an EPS insulation board, the dispersing and mixing drum 2 continuously mixes to ensure the fluidity of the mortar. Secondly, the secondary mixing by the sawtooth mixer 14 ensures that the mortar is finer and will not clump together, thereby ensuring the overall quality after being poured into the EPS insulation board.
