A method for feeding and discharging materials in an aggregate transition bin and an aggregate transition bin for realizing the method

Abstract

The invention relates to a method for feeding and discharging of an aggregate transition bin and the aggregate transition bin for realizing the same. The method comprises the following steps of: dividing an inner part of the aggregate transition bin into a stone transition bin and a sand transition bin according to the proportion of stones and sands needed by stirring concrete, wherein the stone transition bin is higher than the sand transition bin, discharging holes of the stone transition bin and the sand transition bin are respectively communicated with an inner part of a stirring main machine through an emptying door device; feeding stones and sand into the aggregate transition bin; and finally, emptying into the stirring main machine from the aggregate transition bin. According to the aggregate transition bin for realizing the method, the stones enter into the transition bin so as to fill up the stone transition bin in the transition bin, and the sand enters into the transition bin so as to enter into the sand transition bin through an overflowing action of the stone bin, so that the sand and the stones enter into the aggregate transition temporary storage bin of the main machine in batches, the feeding of the sand and the stones in batches is realized, and the demand of twice feeding the sand and the stones in a sand pulp wrapping stone method is met.

Description

technical field [0001] The invention belongs to the field of concrete mixing equipment, and specifically relates to a method for feeding and discharging materials into and out of an aggregate transition chamber for realizing the mortar-wrapped stone method mixing process and the aggregate transition chamber for realizing the method, which can be used in an existing concrete mixing station . Background technique [0002] The traditional concrete mixing process is to put stones, sand, cement, water and admixtures and other raw materials into the mixer for mixing. After mixing evenly, it is qualified concrete. With the continuous development of the mixing process, there has been a mortar-wrapped stone mixing process, that is, sand, cement, and water are first put into the mixing machine for mixing for a period of time, and then stones are added for mixing. Experiments have proved that under the same formula, the concrete strength can be increased by 10% to 20% by using the mor...

Problems solved by technology

[0003] The aggregate transition bin used in the existing mixing plant is usually a single outlet and single bin type. When using the mortar-wrapped stone method to mix concrete, the sand and gravel need to be transported twice, which will easily lead to longer aggregate delivery cycles. Reduced station productivity
