Description

Technical Field

[0001] The invention relates to the technical field of concrete expansion agent storage, in particular to drying equipment for concrete expansion agent production. Background Art

[0002] Concrete expansion agent storage is a method of storing concrete expansion agent. Since the endosperm of concrete expansion agent is directly exposed to the outside, it is easily affected by external environmental conditions such as humidity and heat, and is easy to absorb moisture, causing heat and deterioration. Therefore, the concrete expansion agent is stored inside the drying equipment used for concrete expansion agent production.

[0003] In the prior art, there is a drying device for producing concrete expansion agent with publication number CN112254436A. The invention discloses a drying device for producing concrete expansion agent, including a box body connected with a feed pipe, a premixing box, a servo motor, and a hot air blower are fixedly installed in the box body, and the premixing box is connected to the bottom of the feed pipe, a dredging mechanism is installed between the feed pipe and the box body, a stirring rod is rotatably installed in the premixing box through a rotating rod, a feed pipe is fixedly installed on the premixing box through a cover body, and a filter plate is fixedly installed at the bottom of the premixing box, a drying box is fixedly installed in the box body through a plurality of support columns, and a discharge pipe is connected between the drying box and the box body, and a roller is rotatably installed between the driving end of the servo motor and the drying box.

[0004] In conjunction with the above application, the above application can break up the blocky expansive agent by pre-mixing the expansive agent so that it will not condense, and adopts a sprinkling method to make the expansive agent float in the drying box, so that the expansive agent is more fully in contact with the hot air, and the drying efficiency is higher. However, the existing drying equipment for concrete expansive agent production still has the following problems:

[0005] Generally, drying equipment for producing concrete expansive agents uses the same space to receive and store concrete expansive agents. When concrete expansive agents in a part of the area deteriorate, the concrete expansive agents are prone to breed bacteria, causing the deteriorated area of ​​the concrete expansive agents to spread. When taking out the concrete expansive agents inside the drying equipment for producing concrete expansive agents, it is not convenient to separate the deteriorated area from the good concrete expansive agents. In addition, when observing the storage conditions of the concrete expansive agents inside the drying equipment for producing concrete expansive agents, it is inconvenient to take samples or collect samples. The ventilation method used is likely to carry moisture in the gas, which is likely to accelerate the deterioration of the concrete expansive agent.
