Automatic proportioning device of sand mixer

Abstract

The invention relates to the field of sand mixers, in particular to an automatic proportioning device of a sand mixer. The automatic proportioning device comprises a storage tank. A plurality of vertical partition plates are arranged in the storage tank. The space of the storage tank is divided into a plurality of storage spaces through the multiple vertical partition plates. A discharging pipe is arranged in the position, corresponding to each storage space, of the bottom of the storage tank. A semicircular opening is formed in the bottom of each discharging pipe, and a closable blocking plate is arranged at each opening. Feeding assemblies for opening the blocking plates are arranged in the positions, corresponding to the multiple discharging pipes, of the bottom of the storage tank. The sand mixer is arranged at the bottoms of the feeding assemblies. According to the automatic proportioning device, different required raw materials are poured into the different storage spaces, then the feeding assemblies at the bottom of the storage tank can open the blocking plates at the bottoms of the discharging pipes according to a set program, quantitative conveying of the raw materials is controlled according to the opening time of the blocking plates, thus, automatic proportioning is achieved, and the quality of finished products is improved. In addition, the invention further provides the sand mixer.

Description

technical field [0001] The invention relates to the field of sand mixers, in particular to an automatic batching device for sand mixers. Background technique [0002] The sand mixer is a device that uniformly mixes the components in the molding sand and effectively coats the binder on the surface of the sand grains. The sand mixer uses the relative movement of the grinding wheel and the grinding plate to crush the materials placed between them by rolling and grinding. The sand mixer also mixes the materials while crushing the materials. It is an ideal equipment for producing unburned bricks, lime-sand bricks, cement bricks, refractory bricks, crushed and mixed fly ash, boiler slag, tailings slag and industrial waste slag as raw materials for brick making. In terms of batching in the prior art, the manual batching method is usually used to complete the batching. This batching method requires a lot of labor and needs to pour various raw materials into the sand mixer many time...
