Detailed Description
The invention is described in detail below with reference to the figures and examples.
As shown in fig. 1, the present invention provides a mixing device, which comprises a rotary base and a heat dissipation mixing tank; the heat dissipation mixing tank is mounted on the rotary base so that the heat dissipation mixing tank can rotate. Timely heat dissipation when guaranteeing the compounding through heat dissipation compounding jar avoids the high temperature to lead to the condition of raw materials sintering.
As shown in fig. 2, the rotating base comprises a driving mechanism, a transmission mechanism and a bottom plate 8; the driving mechanism and the transmission mechanism are arranged on the bottom plate 8 and are in driving connection with the transmission mechanism; the transmission mechanism is matched with the roller 9 to drive the roller 9 to rotate. The transmission mechanism comprises a driving shaft 4 and a driven shaft 6; the driving shaft 4 and the driven shaft 6 are arranged on the bottom plate 8 and are arranged in parallel; the driving mechanism is in driving connection with the driving shaft 4; the driving shaft 4 is in contact with the drum 9 to drive the drum 9 to rotate. The parts of the driving shaft 4 and the driven shaft 6 which are contacted with the roller 9 are replaced by the high-temperature resistant roller 5. The driving mechanism is a stepping motor 1, the stepping motor 1 is connected with a driving shaft 4 through a coupler 3, the driving shaft 4 is driven to rotate, and the shaft drives the high-temperature-resistant roller 5 to rotate. In the embodiment, the driving shaft 4 and the driven shaft 6 are arranged on the bottom plate 8 through a bearing seat 7; be provided with motor mounting panel 2 on the bottom plate 8, step motor 1 and shaft coupling 3 set up respectively in motor mounting panel 2 both sides, so be convenient for the motor change.
As shown in fig. 3, the heat-dissipating mixing tank includes a drum 9, a
In this embodiment, the surface of the high temperature resistant roller 5 is sleeved with a high temperature resistant fluorine rubber ring and/or the roller 9 is provided with a knurl. The high-temperature resistant fluorine rubber ring can increase the friction force between the high-temperature resistant fluorine rubber ring and the roller 9. The heat dissipation mixing tank is driven to rotate under the action of friction force. The friction between the roller 9 and the roller can be further increased by knurling the contact area of the roller 9 and the roller.
The movement of the raw materials inside the mixing tank is shown in figure 4. Because the baffle exists, the raw materials are forced to rotate and lift a certain distance along with the inner wall of the tank body, and when the raw materials reach the highest position, the raw materials are downwards leaked or thrown to the inner wall of the tank body under the action of gravity. The raw material powders collide with each other and impact to be mixed. Then the raw material is brought to a high place by the clapboard, and the process of throwing, falling, colliding and impacting is repeated. The raw materials are continuously mixed in the continuous collision and impact process and finally tend to be uniformly mixed.
The radiator is a finned radiator, the internal temperature of the mixed raw materials can be reduced to below 600 ℃, and the problem of raw material sintering in the mixing process is completely avoided. The rotating speed, time, forward and reverse rotation and the like of the whole material mixing process are completely controlled by a program to act by the stepping motor.
The invention can avoid the problem of raw material sintering in the mixing process, greatly reduces the surface temperature of the mixing barrel, and greatly reduces the risk that the gloves are burnt by high temperature when the gloves are worn on a rubber glove box. The invention adopts a modular design, and the material mixing device can be easily assembled when an installer wears heavy gloves in a narrow and small glove box environment. The mixing device is small in size, and the effective volume of the glove box is greatly saved. Mixing tank adopts the plug-in mode to install in radiant type fin radiator, and mixing tank end cover adopts fast card flange and mixing tank barrel sealing connection, and the closing cap that uncaps is quick convenient. When feeding, only need extract the compounding jar, loosen quick cutting ferrule lock nut, just can open the lid, then pack into the raw materials, the cutting ferrule has been installed again, locks quick cutting ferrule lock nut, feeds and accomplishes promptly. And then inserting the mixing tank into the radiation type fin radiator, and then placing the whole radiating mixing tank on a rotary base of the mixing tank. The reverse steps are adopted when unloading. The loading and unloading operation is quick and convenient, the operation time is greatly reduced, and the radiation dose to personnel is effectively reduced.
