Description

Technical Field

[0001] The utility model belongs to the technical field of drag reducing agent processing, in particular to a drag reducing agent premixing device. Background Art

[0002] Patent application No. 202221825441.1 discloses a drag reducer premixing device, including a bottom plate, a stirring mechanism and a dumping mechanism, etc. The dumping mechanism is provided, and the threaded column is driven to move. The threaded column is vertically lifted and lowered under the limit of the baffle and the limit rod, so that the open end of the mixing drum is lowered, and the mixed drag reducer is dumped for use, which solves the problem that after the existing premixing device mixes the drag reducer, it is difficult to take out the mixed drag reducer, and the drag reducer cannot be poured out quickly, which increases the difficulty of operation. A stirring mechanism is provided, and the drag reducer is fully mixed by driving the stirring blades to rotate. The filter screen blocks the unmixed drag reducer in the stirring area on the left side of the mixing drum, and the fully mixed drag reducer can pass through the filter screen and be taken out from the opening on the right side of the mixing drum for use.

[0003] However, the above-mentioned disclosed patent scheme still has the following defects: during premixing, the motor is in working state, the mixing drum will vibrate, and the vibration force is transmitted to the spring telescopic rod for extension and contraction, causing the mixing drum to tilt and shake to the lower right during premixing and unable to be in a stable state. During discharging, the mixing drum is in a state of tilting to the lower right, and the unmixed drag reducer will accumulate in the lower part of the left side of the filter, causing the fully mixed drag reducer to be blocked and can only be discharged from the mesh above the filter, resulting in a low discharge speed of the fully mixed drag reducer.

[0021] Working principle: In the utility model, the drag reducer and other raw materials that need to be premixed are placed into the mixing drum 3 from the feed hopper 4, and the motor 6 is started to drive the rotating rod 7 to rotate forwardly. The rotating shaft 8 drives the stirring blade 9 to rotate along with the rotating rod 7, and then the stirring blade 9 premixes the materials in the mixing drum 3 during the rotation process. When the premixing is completed and the material needs to be discharged, the electric push rod 12 is started to drive the movable rod 13 to move to the left, and the movable rod 13 drives the sliding sleeve 15 and the roller 19 to move. The roller 19 rolls synchronously to the left on the bottom plate 1, and the sliding sleeve 15 slides synchronously to the left along the sliding rod 141, and the valve 11 is opened. The fully mixed materials in the mixing drum 3 pass through the mesh of the filter screen 10, and pass through the valve 11 at the discharge port, and are finally discharged from the discharge hose 16 to the container for collecting materials. In this process, the unmixed filling The separated materials will gradually accumulate at the lower part of the left side of the filter screen 10, and the amount of materials discharged from the discharge hose 16 can be observed. If the discharge amount is small, it means that the discharge of the fully mixed materials is hindered, and the motor 6 is started to drive the rotating shaft 8 to reverse, and the rotating shaft 8 drives the connecting rod 17 to move, and the connecting rod 17 drives the mesh frame 18 to move, and then the mesh frame 18 passes through the lower part of the left side of the filter screen 10 during rotation, and the materials accumulated here are shoveled into the mesh frame 18, and then the subsequent materials can continue to be discharged from here, and the unmixed materials collected in the mesh frame 18 remain in the mesh frame 18, and at the next premixing, when the motor 6 rotates forward, they are discharged from the opening of the mesh frame 18 and continue to participate in the premixing. After the discharge is completed, the electric push rod 12 drives the movable rod 13 to move rightward and reset, completing the entire premixing work.
