Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically a vertical twin-shaft large-capacity mixer for fluidized solidification soil. Background Technology

[0002] The vertical twin-shaft large-capacity mixer for fluidized bed solidification is mainly used for road base filling, building foundation pit backfilling, and mine tailings treatment, especially suitable for large-scale projects with high requirements for mixing uniformity and construction efficiency. This device uses counter-rotating mixing paddles to generate strong shear force, improving material uniformity, and is particularly suitable for high-viscosity fluidized bed solidification soil. Dynamic crushing function: Some models add impact plates to the outside of the mixing shaft, combining the centrifugal force of the auger with mechanical impact force to achieve simultaneous material crushing and mixing. Foundation-free modular design: The mobile mixing plant does not require a fixed foundation and can be quickly deployed to the construction site, reducing installation costs.

[0003] Currently, the vertical twin-shaft large-capacity mixer for fluidized bed solidification mainly uses two augers inside the drum to mix materials. The inside of the drum is usually cleaned by workers using hand hoses and other cleaning tools. However, due to the large volume of the drum and the obstruction caused by the augers and other related structures, it affects the cleaning of the augers and the inner wall of the drum, thus reducing the cleaning efficiency of the inner wall of the vertical twin-shaft large-capacity mixer for fluidized bed solidification. Utility Model Content

[0004] The purpose of this invention is to provide a vertical twin-shaft large-capacity mixer for fluidized bed solidification, so as to solve the problem of troublesome cleaning of existing vertical twin-shaft large-capacity mixers for fluidized bed solidification.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical twin-shaft large-capacity mixer for fluidized bed solidification, comprising a machine body, a cylinder body disposed within the machine body, and a support frame slidably connected thereto. A lifting frame is slidably connected within the cylinder body, with both sides of the lifting frame in contact with the inner wall of the cylinder body. A discharge pipe is fixedly connected to one side of the cylinder body, and a switch valve is disposed on the discharge pipe. An agitation assembly is disposed within the lifting frame. Vertical screws are rotatably connected to the inner walls of both sides of the support frame. A first threaded sleeve is threaded onto the outer side of each of the two vertical screws. An L-plate is fixedly connected to one side of each of the two first threaded sleeves. The two L-plates are respectively fixedly connected to the two sides of the top of the lifting frame.

[0006] Preferably, a first connecting rod is rotatably connected to the inner wall of the support frame, and first bevel gears are threaded onto both ends of the first connecting rod and the bottom ends of the two vertical screws. The two first bevel gears on the first connecting rod are respectively meshed with the first bevel gears on the two vertical screws.

[0007] Preferably, a transverse screw is rotatably connected to the inner wall of the machine body, and a second threaded sleeve is threaded on the outer side of the transverse screw. The second threaded sleeve is fixedly connected to the inner wall of the support frame, and the vertical screw and the transverse screw are arranged perpendicular to each other.

[0008] Preferably, the agitation assembly includes two auger rods, the top ends of which are rotatably connected to the top wall inside the lifting frame. A second connecting rod is rotatably connected to the upper part of the lifting frame. The two ends of the second connecting rod and the top ends of the two auger rods are threaded with second bevel gears. The two second bevel gears on the second connecting rod are respectively meshed with the second bevel gears on the two auger rods.

[0009] Preferably, engines are installed on the body, the support frame, and the lifting frame, and the output ends of the three engines are respectively connected to one end of the transverse screw.

[0010] Preferably, rollers are provided at the four corners of the bottom of the support frame, and the bottom of the rollers contacts the bottom wall inside the machine body.

[0011] Preferably, two stabilizing rings are fixedly connected to the outer side of the lifting frame, and both stabilizing rings slide within the cavity of the cylinder.

[0012] Preferably, the upper part of the lifting frame is provided with a groove, the second bevel gear and the second connecting rod are both disposed in the groove cavity, and a protective cover is installed at the groove opening.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application improves the cleaning convenience of the vertical twin-shaft large-capacity mixer for fluidized solidification soil by setting up a liftable lifting frame and installing an agitator on the lifting frame, which makes it easy to remove the agitator and facilitates the cleaning of the agitator and the inside of the cylinder.

[0015] 2. This application sets up a support frame, which slides laterally to drive the agitator component away from the cylinder. This allows workers to clean the cylinder and the agitator component separately, further improving the cleaning convenience of the vertical twin-shaft large-capacity mixer for fluidized solid soil.

[0016] 3. This application utilizes a diesel engine, providing strong and stable power output, enabling continuous and stable operation under complex working conditions and high loads, ensuring the efficient operation of the mixer. Compared to electric drive, it eliminates the limitations of power cabling, making it particularly suitable for remote areas, field construction sites, or areas with unstable power supply, significantly improving the equipment's applicability and operational flexibility.

[0017] 4. This application employs a vertical twin-shaft mixing structure, where two auger rods rotate simultaneously, creating a unique mixing flow field that generates strong shearing, compression, and tumbling effects on the materials. This significantly shortens mixing time and improves production efficiency. Whether the materials are fluid or viscous, uniform mixing can be achieved, ensuring a high degree of consistency in mixing quality.

[0018] 5. This application adopts a container-style design, which is compact, has high space utilization, and is convenient for transportation and installation. It integrates the power system, mixing system, and control system within a limited space, occupying a small area and allowing for flexible deployment at various construction sites, effectively saving site resources.

[0019] 6. This application utilizes a container structure design, thus possessing standard container dimensions and interfaces. It can be directly transported via various modes of transport such as road, rail, and waterway without the need for dismantling or special transport equipment, resulting in low transportation costs and high efficiency. Upon arrival at the construction site, installation and commissioning can be completed quickly, enabling rapid deployment and significantly improving the timeliness of project construction.
