Description

[0002] When processing concrete, it is usually necessary to mix the raw materials. The mixing operation is usually completed in the corresponding mixing equipment. At present, there are many types of concrete mixing equipment on the market, some of which also have a heating function, and the heating process is generally completed by introducing steam. The heating type mixing device is provided with a steam inlet pipe and a steam exhaust pipe. As the steam is introduced along the inlet pipe, the inside of the mixing equipment can be heated to achieve the effect of heating and mixing.
[0003] However, when this type of steam heating and mixing device is used, since it directly introduces steam between the inner and outer tanks of the mixing tank, due to the high fluidity of steam, although the steam inlet pipe and the steam exhaust pipe are respectively arranged on both sides, the steam is more likely to be discharged directly along the steam exhaust pipe, resulting in a shorter residence time of the steam in the mixing tank, further resulting in insufficient heat exchange, and finally, the discharged steam still contains a lot of heat that is not utilized, affecting the heat exchange effect and the thermal utilization rate of the steam, causing inconvenience to the user. In view of this, we propose a concrete steam heating and mixing device. Utility Model Content
