How to stably improve the mixing efficiency of soil mixing station?

The production efficiency of the stabilized soil mixing station determines the progress of the entire project. The quality of mixing is also related to the quality of the project. In order to ensure the mixing quality and mixing efficiency, an excavator can be used to tip over to balance the moisture content of the raw materials. Since the moisture content of black ash and white ash is determined by many uncertain factors, especially white ash, the digestion quality, its own quality, and whether it is screened all affect the use efficiency of white ash. 

Therefore, before use, it is necessary to ensure the most suitable construction moisture content of white ash and to grasp the appropriate stacking time. After opening the stack, if it is too wet, you can use an excavator to turn it over several times until the appropriate moisture content is reached, which not only ensures construction efficiency but also ensures the amount of ash. 

The location of the stabilized soil mixing plant is also very important. In particular, whether transportation within the site is smooth is also related to production efficiency. Because in production, not only the loading efficiency of the loader must be taken into consideration, but also the transportation vehicles must not be stagnant and blocked, and the feeding vehicles must not affect the construction on site. In addition, the loader should load the material after the material picker has finished clearing the material on the silo screen, so as to facilitate the work of the picker; but it cannot load the material too late, otherwise the material will be cut off. 

Therefore, the improvement of the efficiency of the stabilized soil mixing station is comprehensively affected by many factors, and requires close cooperation between man and machine, external factors, and internal factors. 

To ensure the safe operation of the mixing station, three parts should be strictly monitored:

1. Safety requirements for the electrical system of the mixing station When selecting equipment, the safety requirements for the electrical system include: The equipment console should be equipped with an emergency power-off switch, which should be able to cut off the main power supply in an emergency. The emergency power-off switch cannot automatically reset. The access cover and opening and closing power supply of the forced mixing host should be equipped with an interlock device. When the access cover is opened, the power supply should be cut off, and the host cannot start. In the basic design of the mixing station, a special grounding network should be considered, with reliable electrical connections to the building and powder silo. The grounding resistance should not be greater than 10Ω. The computer control system should be equipped with an independent grounding network, and the grounding resistance should not be greater than 4Ω. 

2. Safety requirements for structural components The standard for commercial concrete mixing stations stipulates that safety protection devices should be installed on the mixing station operating platform, feed materials, aggregate silos, cement silos and other parts involving personal safety. Exposed parts of the transmission system should have protective devices and safety inspection protection devices. The width of the platform and walkway should be no less than 50cm, and skirting boards with a height of no less than 5cm should be installed on the edges to prevent tools, metal and other materials from falling into the gaps between the walkway pedals and causing personal injury or death. 

3. Safety design of the mixing station foundation. The design of the mixing station foundation should be designed and confirmed by designers with construction qualifications based on the local geology or the actual conditions understood by the implementation site. The allowable compressive stress of the ground is generally 0.2~0.3MPa, and the foundation strength is calculated according to the GB5007 standard. For harder soil, generally only the bottom layer is required to be paved after excavation, and then the foundation concrete can be poured. Generally, C30 concrete is used. After the soft foundation is excavated, different techniques must be selected to reinforce the bottom of the foundation according to the degree of filling after excavation. Commonly used reinforcement methods for mixing stations include driving plum blossom piles or increasing the foundation area to increase the foundation bearing capacity and prevent future foundation cracking and sinking from causing hidden dangers to equipment and production.
