[0017] (III) Beneficial effects
[0018] The present invention provides an extrusion device for continuously extruding an activated carbon filter element with a single screw, which has the following beneficial effects:
[0019] (I) The extrusion device of the single-screw continuous extrusion activated carbon filter element is provided with a feeding device. When the equipment is in use, the rotating shaft drives the spiral strip to rotate. The activated carbon and the adhesive are stirred by the spiral strip in the process of falling along the feed barrel. When the material is discharged to a certain thickness, the plug plate is inserted, and the cycle is repeated. After the discharge is completed, the pressing plate is pressed downward, and the lower surface of the sleeve restricted by the adjusting rod contacts and extrude the upper surface of the plug plate, and the lower surface of the pressing plate contacts and extrude the uppermost material. In the discharge stage, the feeding device is responsible for stirring the material to make the material mixture more uniform, and at the same time assists the feeding, thereby solving the problem that the traditional feeding equipment extrusion molding easily leads to the compaction of the inside of the filter element.
[0020] (ii) The extrusion device for the single-screw continuous extrusion of the activated carbon filter element is provided with a die pressing device. When the equipment is in use, the material is fed into the interior of the concave plate by the feeding device, and the partition device is inserted into the interior of the concave plate in sequence. Then, the pressing plate is pressed down, and the lifting rod drives the concave plate to move downward, and the concave plate is retracted into the interior of the heat preservation device. Then, the heating device works, and heat enters the interior of the concave plate through the through hole and is transferred upward at the same time. The material fills the gap between the concave plate and the pressing plate and is thermoplastically formed in the gap. After the forming is completed, the concave plate and the pressing plate are separated, and the filter element plate is opened and dropped off, thereby solving the problem of poor die pressing effect during the manufacturing of traditional filter elements.
[0021] (III) The extrusion device of the single-screw continuous extrusion activated carbon filter element is provided with a thermal expansion device. When heat enters the interior of the concave plate, the temperature inside the hollow structure of the concave plate increases, the gas inside the gas cylinder expands due to the heat, and the vertical rod is pushed upward. During the upward movement of the vertical rod, the top end of the vertical rod pushes the cam to rotate, and the outer surface of the cam presses against the inner surface of the concave plate, and the concave plate expands. During this process, the contact point between the cam and the concave plate is squeezed, the contact point pressure increases, and the pressure at both ends remains unchanged. The inner cavity interlayer of the concave plate is deformed outward in an arc shape, and the surface of the concave plate squeezes the thermoplastic inside the concave cavity. The concave plate is made of elastic steel and has a certain plasticity. The material is thermoplastically solidified. When the mold is to be opened, the material and the equipment are cooled. According to the principle of thermal expansion and contraction, the thermal expansion device shrinks, the concave plate is reset, the material and the inner surface of the concave plate are automatically separated, and the demolding is completed, which solves the problem that the traditional filter element cannot be automatically demolded during discharge.
[0022] (IV) The extrusion device of the single-screw continuous extrusion activated carbon filter element is provided with a heating device. When the equipment is in use, the turntable drives the stirring rod to rotate, and the fuel enters the interior of the combustion chamber from the feed port, and the outside air enters the combustion chamber through the intake pipe to participate in the combustion. The fuel and air are stirred and mixed inside the combustion chamber and are finally ignited. The heating device is responsible for the thermoplastic filter element. The heating device can make the fuel burn fully, which solves the problem of insufficient combustion of the fuel inside the equipment during the thermoplastic stage of the traditional filter element.
[0023] (V) The extrusion device for the single-screw continuous extrusion of the activated carbon filter element is provided with a separation device. When the equipment is in use, the outer surface of the side plate is stuck to the outer surface of the concave plate, the opening and closing device slides along the inner surface of the side plate, and the plug plate is inserted into the inside of the side plate. During this process, the plug plate is pressed against the rotating plate, and the rotating plate presses the sliding plate downward during the rotation. The sliding rod retracts into the inside of the sealing chamber, the pressure inside the sealing chamber increases, and the plug plate separates the concave plate. The molding of multiple thin filter elements can be completed at one time. When it is desired to complete the molding of a thick filter element, the plug plates can be pulled out. This solves the problem that the size of traditional filter elements is fixed during production and the models that can be produced are limited.
[0024] (VI) The extrusion device of the single-screw continuous extrusion activated carbon filter element is provided with a heat preservation device. When the equipment is in use, the movable plate moves along with the movement of the concave plate. The movable plate prevents heat leakage. The outer cover wraps the concave plate. During the operation of the heating device, the high-temperature exhaust gas flows along the gap between the outer surface of the concave plate and the inner surface of the outer cover. The exhaust gas in the gap forms a heat preservation layer. The right end of the clamping rod abuts against the outer surface of the concave plate, and the tension spring is stretched to prevent the concave plate and the outer cover from shaking and deviating. After the gap is filled, the exhaust gas flows into the exhaust pipe along the reflux pipe and is finally discharged to the outside. The heat preservation device can further utilize the heat in the exhaust gas, effectively reduce the fuel consumption, and solve the problem of low heat utilization rate in the manufacture of traditional filter elements.
