Description

Technical Field

[0001] The utility model relates to the technical field of gelling materials, in particular to a mixing device for preparing solid waste-based gelling materials. Background Art

[0002] Cementitious materials, also known as cementing materials, can be transformed from slurry into a solid stone-like body under physical and chemical effects, and can cement other materials to form a composite solid substance with a certain mechanical strength. Solid waste-based cementitious materials are hydraulic cementitious materials made of solid waste such as steel slag, slag, and metallurgical desulfurization ash as raw materials, which are processed and ground into a certain proportion.

[0003] When preparing cementitious materials, a mixing device is also required to mix a variety of raw materials. However, most existing mixing devices use a single stirring shaft driven by a motor to stir the raw materials. The raw materials can only be mixed and stirred in one direction, which not only affects the efficiency, but also the stirring quality is relatively general. In addition, when the device is stirring, in order to prevent the raw materials from being too dry and affecting the stirring effect, a certain amount of water needs to be added. At the same time, water needs to be injected to clean the kettle after stirring, but the existing mixing device is inconvenient to inject water, which affects the use of the device. In summary, the existing mixing devices still have the following problems:

[0004] 1. Most existing mixing devices use a single stirring shaft driven by a motor to stir the raw materials, which not only affects the efficiency, but also the stirring quality is relatively average; 2. It is inconvenient to inject water into the device before and after stirring, which affects the use of the device. Utility Model Content

[0005] The main purpose of the utility model is to provide a mixing device for preparing solid waste-based gelling materials, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

When the device is stirring the raw materials or when water needs to be injected into the stirring kettle body after stirring, the water in the water tank is pumped out by the water pump on the water injection device and the water is transported to several nozzles on the connecting seat through the connecting pipe. The nozzles then spray the water into the stirring kettle body through the connecting port, which further improves the stirring effect of the device or facilitates the cleaning of the kettle body.

[0016] 3. The design of the dust-proof net in the connection port can prevent dust from entering the nozzle through the connection port when the device is stirring the raw materials, causing the nozzle to be blocked. In addition, the nozzle is located in the connection port, which can also prevent the nozzle from being scratched by the outside, thereby increasing the service life of the nozzle.
