Tank lorries for pumping solid raw materials {TANK LORRY FOR SQUEEZE PUMPING SOLID RAW MATERIAL}

The present invention relates to a tank lorry for pumping solid raw materials, and more specifically, when loading solid raw materials into a compartment provided inside a tank, the possibility of dust generation is suppressed, and at the same time, the solid raw material is loaded into the compartment, and the solid material is discharged from the compartment It relates to a tank lorry for pressure-transferring a solid material capable of effectively carrying out a process of doing so.

In general, the transport of solid raw materials such as quicklime is loaded and transported in a so-called tank lorry, which is a transport vehicle in a factory. At this time, a squeeze pumping method is applied to the tank lorry to discharge the loaded solid material to the outside of the tank through pressure applied inside the tank.

Referring to FIG. 1 , in the conventional tank lorry, a tank 20 provided with compartments for storing solid raw materials 1 is installed in a vehicle 10, and a plurality of compartments are provided inside the tank 20 along a partition wall 20a. is partitioned by

Since the solid raw material has an excessively low flowability compared to the liquid raw material, in order to effectively load the inside of the tank 20, it is necessary to divide the internal space of the tank 20 into a plurality of compartments and provide individual inlets for each compartment. there is.

Accordingly, the solid raw material 1 is dropped into the compartment after being placed on the top of each inlet through a separate supply device 30.

At this time, a large amount of dust 1a may be generated due to the solid raw material 1, and the dust 1a not only contaminates the vehicle, but also causes a decrease in the durability of the tank 20. In addition, the dust (1a) is pointed out as a cause of not only contamination of the vehicle, but also contamination of the surrounding environment or occupational diseases of workers.

Therefore, in recent years, attempts have been made to install a dust collection device for each compartment of the tank lorry to treat the dust 1a.

On the other hand, in the case of the conventional loading method using a tank lorry, a plurality of compartments are partitioned inside the tank 20, and the solid raw material 1 is loaded while moving the supply device 30 to the inlet provided for each compartment. This not only generates unnecessary movement, but also requires a more efficient loading method of the solid raw material 1 because the working time is also long, and for this, the structure of the tank lorry also needs to be improved.
