FIGS. 1 , 2, 3 and 4, a feeding device for liquid materials in accordance with the present invention comprises a storage tank (10) and a hydraulic cylinder (20). - The storage tank (10) comprises an outer tube (11), an inner tube (12), a receiving space, a front cap (13) and a rear cap (16). The outer tube (11) is thermal conductive and has a front end and a rear end. The inner tube (12) is thermal conductive, is mounted coaxially in and spaced from the outer tube (11) and has a front end and a rear end. The receiving space is defined between the inner and outer tubes (11, 12).
- The front cap (13) is mounted on the front ends of the inner and outer tubes (11, 12) and has a feeding inlet (14) and a front outlet (15). The feeding inlet (14) is defined in the front cap (13), communicates with the inner tube (12) and may be connected to a divider connected to a liquid material supply and a liquid material output through pipelines. The front outlet (15) is defined in the front cap (13), communicates with the receiving space and may be connected to a recycle device.
- The rear cap (16) is mounted on the rear ends of the inner and outer tubes (11, 12) and has a rear inlet (17) and a gas opening (18). The rear inlet (17) is defined in the rear cap (16), communicates with the receiving space between the inner and outer tubes (11, 12) and may be connected to a supply of hot and cold water through a pipeline. The gas opening (18) is defined through the rear cap (16) and communicates with the inner tube (12).
- The hydraulic cylinder (20) is connected to the storage tank (10) and has a piston rod (21) and a piston (22). The piston rod (21) is mounted through the rear cap (16), extends into the inner tube (12) and has a distal end. The piston (22) is connected to the distal end of the piston rod (21) and is mounted movably in the inner tube (12). When the hydraulic cylinder (20) is actuated, gas can flow in or out through the gas opening (18) of the rear cap (16).
- When the feeding device is in use, a liquid material (30) is fed into the inner tube (12) through the feeding inlet (14) of the front cap (13). The piston rod (21) of the hydraulic cylinder (20) drives the piston (22) to perform a reciprocating and linear movement and press against the liquid material (30) in the inner tube (21).
- Hot water can be introduced into the receiving space through the rear inlet (17) of the rear cap (16) to heat the liquid material (30) in the inner tube (12). Thus, the flow property of the liquid material (30) can be adjusted and the liquid material (30) can be fed at a suitable working temperature. Cold water can also be introduced into the receiving space through the rear inlet (17) of the rear cap (16) to cool the liquid material (30) in the inner tube (12). Thus, the liquid material (30) can be adjusted to a suitable temperature so as to facilitate the operation of the hydraulic cylinder (20). Hot and cold water can be delivered to the recycle device through the front outlet (15) of the front cap (13) and recycled to the supply of hot and cold water.
- With reference to
FIGS. 5 and 6 , multiple storage tanks (10) can be connected coaxially in series and driven simultaneously by the hydraulic cylinder (20). The piston rod (21) of the hydraulic cylinder (20) extends through or into the inner tubes (12) of the storage tanks (10) and multiple pistons (22) are connected to the piston rod (21) and mounted respectively in the inner tubes (12) of the storage tanks (10). Thus, the piston rod (21) can drive the pistons (22) to pressing against the liquid material (30) in the inner tubes (12). - With reference to
FIG. 7 , multiple storage tanks (10) are arranged in parallel. Multiple hydraulic cylinders (20) are connected respectively to the storage tanks (10) and are connected to a hydraulic supply (40) through multiple pipelines. Thus, the hydraulic cylinders (20) can drive the storage tanks (10) with the same hydraulic supply (40). - The feeding device has a simplified structure and a low manufacturing cost and is easy to repair and maintain. Additionally, the feeding device is quiet because of the stability of the hydraulic cylinder (20). Furthermore, by means of the design of the inner (12) and outer tubes (11), the liquid material (30) in the inner tube (12) can be heated or cooled by introducing hot or cold water into the receiving space. The viscosity of the liquid material (30) can be adjusted and feeding liquid materials in different viscosities by the feeding device is easy and convenient.
