STORAGE HOPPER
Storage Hopper is the equipment employed for storing solidifying agent raw materials. A set of equipment usually includes one or two storage bins to load different solidifying agent raw materials respectively. The solidifying agent raw materials are automatically transported to the control center through the conveying pipeline from the lower funnel for configuration.The shape of the storage bin can be vertical or horizontal. The common specifications are 50 ton and 80 ton Hopper. If the customer has other size requirements, it can be customized. The bin body and support are made of high-quality steel, with stable structure, firm welding and long service life.
A material level alarm is set. When the internal solidified materials (cement, fly ash, lime, slag micro powder, etc.) are higher or lower than a certain value, it will automatically alarm and stop the system.
Capacity | Diameter | Height |
|---|---|---|
50 Tons | 2.8 metre | 9 metre |
80 Tons | 3.2 metre | 12 metre |
CONTROL CENTRE
The control center is a container type equipment controlled by computer full-automatic PLC (programmable logic controller) to configure and mix the solidifying agent according to a certain proportion, also transmitting the solidifying agent to the power mixer.
The device is made of quality steel, with a long square style design and installed with a door. You can enter the control center to check the working status of the control panel and mixer. The shell helps protect the internal device from the influence of the environment, improve the mixing efficiency and prolong the service life.
It is composed of controller, upper stirrer, lower stirrer and water tank. It has two operation modes, automatic and manual. In automatic mode, you can start and stop with one button by inputting various values in the control panel, such as solidifying agent ratio, pressure, conveying rate, etc. the operation is simple. In manual mode, various values still need to be input, but can be adjusted at any time according to the solidification situation, which has greater flexibility and is conducive to better solidification effect.
The controller is the core part of the control center, which is used to control the mixing and transportation of solidifying agent. The controller works according to the preset solidifying agent ratio, pressure and conveying rate. The material ratio is obtained according to the pre-test results, and the conveying rate is selected according to the size of the excavator and the rotating speed, temperature and volume of the power mixer.
The pressure setting is selected according to the depth of the power mixer. Generally, the deeper the power mixer reaches, the greater the back pressure will be, the greater the transmission pressure setting. Refer to the instructions of user instruction and Vanrock's specialist for details.
In the construction process, after the controller is started with one key, the control center starts to work. The solidifying agent raw material and water enter the upper stirrer through the transmission pipeline according to the preset ratio to mix and stir to form a mixture. The mixture enters the lower stirrer through the pipeline for further mixing, and finally forms a solidifying agent with good solidification effect, which is transmitted to the front power mixer through the hose pressure and acts on the sludge.
It is also equipped with a monitoring system to monitor the actual weight of solidifying agent raw materials and water, the weight of upper stirrer and lower stirrer, the switching state of each pump and the mixing countdown in real time. The engineer can know the working status and adjust it at any time to ensure the normal operation of the equipment.
