The tank assembly contains a supporting element provided between the chassis and the container as well as a driving unit that gives agitating action to the container -located on the supporting element- on the chassis when activated. It is also possible to heat up the liquid inside the tank assembly in a balanced manner as a result of the agitating action provided by the driving unit. During the heating of the liquid in the container, agitation process is applied for the stabilized heat transfer from the heated surface to the other parts. Due to the agitation process, the heated liquid reaches to other surfaces thereby raising the liquid temperature in a balanced manner. Due to the combination of the energy generated by agitation process with the heat energy, the time for heating up the liquid in the container is reduced. Reducing the amount of heat energy also provides cost advantage. It is both possible to agitate the tank assembly on a fixed base and also on a moving vehicle.

DETAILED DESCRIPTION OF INVENTION

In this detailed description, the subject matter of the invention has been illustrated by way of non-exhaustive examples that only serve to better explain the subject. Figure 1 shows the perspective view of the said tank assembly. The tank assembly is composed of a rigid container (10) which is made of metallic material with a proper liquid-proof characteristics. The container (10) has a liquid transfer opening (14) provided in its front wall (12). The liquid transfer opening (14) has a circular shape and it should be covered with a sealed lid (15) that fully covers on it. The lid (15) has similar diameters with the liquid transfer opening (14). The container (10) has an opening (16) in a close position to the front wall (12) located on the upper wall (11). Through the opening (16), it is possible to inspect the liquid inside the container (10). The upper wall (11 ) of the container (10) has two platforms (17) to enable the worker to walk on them. The worker on the platform (17) is able to monitor the liquid inside the container (10) through the opening (16). The container (10) is placed onto a rigid chassis (20) via its lower wall (13). The chassis (20) is made of metallic material due to its durable and resistant structure. The chassis (20) is composed of a base (22) and two lateral walls (24). There is a ladder (26) on each lateral wall (24) so as to enable the worker to climb up the platform (17) on the container (10). The container (10) is locked by a corner-locking mechanism (28) upon placing onto the chassis (20). The corner-locking mechanism (28) locks the extensions (18) at the lower part of the container (10). The base (22) of the chassis (20) consists of an underframe (30) to carry the chassis (20) and the container (10) on it. The underframe (30) is made of metallic material. The underframe (30) carries the chassis (20) from its supporting points so as to stabilize the weight of the system. In order the stabilize the weight, a supporting element (32) is used at the center point of the underframe (30). The supporting element (32) consists of a supporting shaft (34). The underframe (30) also accommodates a driving unit (40). The driving unit (40) gives momentum to the container (10) and the chassis (20), especially it initiates agitation process. The driving unit (40) consists of a hydraulic pump (44) and a motor (42) designed to impart torque to the hydraulic pump (44). The hydraulic fluid is pressurized by imparting torque to the hydraulic pump (44) from the motor (42) via electric power. The pressurized hydraulic liquid enables the hydraulic piston (46) provided on the base (22) of the chassis (20) to move. There is a controller (52) that controls the running of motor (42) and connected in such a way that it transmits the signal. The controller (52) enables the motor (42) to run or stop accordingly. The controller (52) is placed into the controlling unit (50) that is controlled by the user. The controlling unit (50) functions to start the agitation process, stop the agitation of tank assembly in case of emergency or stop it when the process is ended.

In order to start agitation process of the tank assembly, first of all, the rigid container (10) which is sealed properly is placed onto the chassis (20). The container (10) which is placed onto the chassis is locked onto the chassis (20) by means of the corner-locking mechanism (28). The Locking system prevents the container (10) from overturning or skidding during the agitation process. A command is sent to the controller (52) located inside the controlling unit (50) to run the motor (42) thereby starting the agitation process the locked container (10). The controller (52) runs the motor (42) in a pre-determined period and at the constant speed. The torque produced by running the motor (42) is imparted to the hydraulic pump (44). The hydraulic fluid is pressurized onto the hydraulic pump (44) and it ensures the actuation of hydraulic piston (46). Vertical movement of the hydraulic piston (46) provides the agitation process of the tank assembly. The supporting shaft keeps the hydraulic piston (46) at its vertical axis during the agitation process. Thanks to the performance of agitation process, the liquid in the container (10) is heated up with minimum energy in a short time. Due to the agitation process, the temperature of the heated surface of the liquid is mixed with the other surfaces thereby ensuring the balance between them. The temperature of the heated liquid is measured by a thermometer (not shown) placed outer surface of the container (10). REFERENCE NUMBERS
