Description
Technical Field
[0001] The utility model relates to the technical field of dust collecting devices, in particular to a dust collecting device for discharging concrete expansion agents. Background Art
[0002] Concrete expansion agent is an additive used in concrete production. It can produce bubbles in concrete, thereby improving the performance of concrete. Expansion agent is usually used in the production of lightweight concrete. It can reduce the density of concrete and improve thermal insulation performance. In addition, expansion agent can also improve the impermeability of concrete and reduce shrinkage deformation, thereby improving the durability of concrete. Common concrete expansion agents mainly include two categories: organic expansion agents and inorganic expansion agents. Organic expansion agents usually produce gas through chemical reactions, while inorganic expansion agents introduce bubbles into concrete by physical means. The selection of appropriate expansion agent can be adjusted according to specific concrete engineering requirements and performance indicators.
[0003] When adding the expansion agent, the dusty expansion agent is easy to float out from the feed port. When the general dust collecting device absorbs the expansion agent, the expansion agent is easy to block the filter screen, resulting in a decrease in the dust collection effect of the device. The expansion agent is difficult to be absorbed into the dust collecting device. The expansion agent floating in the air is easy to enter the body of the staff and cause certain harm. When the general dust collecting device collects the expansion agent, the expansion agent is easy to adhere to the inner wall and bottom plate of the dust collecting box. It is difficult for the staff to control the amount of expansion agent added, which can easily lead to the concrete after mixing being difficult to achieve the expected effect. In view of the above problems, a concrete expansion agent feeding dust collecting device is proposed to solve them. Utility Model Content
