And the working efficiency is greatly improved.

This utility model relates to the field of corrugated paper technology and discloses an energy-saving device for fiber dissociation in corrugated paper packaging waste. It includes a dissociation tank body, a motor fixedly connected to the upper surface of the dissociation tank body, a rotating column fixedly mounted at the output end of the motor, an outer wall of the rotating column rotatably connected to the inner wall of the dissociation tank body, fan blades fixedly connected to the outer wall of the rotating column, an electric push rod fixedly connected to the inner bottom wall of the dissociation tank body, a connecting rod rotatably connected to the inner wall of the filter screen, an outer wall of the connecting rod fixedly connected to the inner wall of the rotating column, and an outer wall of the filter screen slidably connected to the inner wall of the rotating column. A transmission assembly is provided on the inner wall of the dissociation tank body. In this utility model, starting the motor drives the rotating column to rotate simultaneously with the fan blades, causing the rotating rod to rotate the filter screen on the inner wall of the connecting rod. The fan blades effectively reduce energy consumption during the fiber dissociation process.

The application relates to a pharmaceutical raw material crushing device for pharmacy, and relates to the technical field of pharmaceutical raw material crushing. The device comprises a shell, the top of the shell is fixedly connected with a transparent inspection ring, the top of the transparent inspection ring is fixedly connected with a fixed plate, the top of the fixed plate is provided with a preliminary cutting mechanism, the preliminary cutting mechanism comprises a motor one, the driving end of the preliminary cutting mechanism is fixedly connected with a central rotating shaft, the outer portion of the central rotating shaft is fixedly connected with a cutting assembly, the outer portion of the central rotating shaft is fixedly connected with a plurality of vertical blades, and the middle of the vertical blades is fixedly connected with an annular blade. The application has the staggered shearing force formed by the vertical blades and the annular blade, can quickly cut large blocks of raw materials into small blocks, the fixedly connected ring drives the auxiliary cutting blade to preliminarily cut the long strip-shaped raw materials from different angles, improves the raw material processing efficiency, and realizes the high-efficiency crushing effect.

According to the technical scheme, the impact crushing type PDC drill bit assembly comprises a main body and an impact head, the impact head is installed in the middle of the top of the main body, a square connecting column is installed at the bottom of the impact head, an inner groove is formed in the middle of the interior of the main body, and an inner hole is formed in the bottom of the interior of the main body; and a movable column is installed in the inner hole, reverse rings are installed on the two sides, close to the top, of the outer surface of the movable column, a cutter wing is installed on the outer surface of the main body, a conical tooth A is installed on one side of the cutter wing, and a conical tooth B is installed on the portion, located in the gap of the conical tooth A, of the outer surface of the cutter wing. According to the impact crushing type PDC drill bit assembly, the problems that when an existing PDC drill bit drills holes, rock is mainly crushed and drilled through rotating conical teeth, the drilling pressure is relatively fixed, and the rock crushing efficiency is relatively poor are solved, the time needed for rock crushing is shortened, and therefore the drilling efficiency of the drill bit is improved.

The utility model discloses an air-assisted feeding structure of a grading mill, and belongs to the technical field of grading mills. A pneumatic conveying type grading mill feeding structure comprises a grading mill body and further comprises a stock bin fixedly arranged on the outer wall of the grading mill body, a storage bin is formed in the stock bin, a discharging pipe is fixedly arranged at the bottom of the storage bin, and a material grinding roller used for grinding materials is rotationally arranged in the discharging pipe; the spiral conveying pipe is fixedly arranged on the grading mill main body; when the spiral conveying pipe is started to convey materials into the grading mill body, the materials in the storage bin flow into the spiral conveying pipe through the discharging pipe, the grinding roller is driven to rotate, and under extrusion of the outer wall of the grinding roller and the inner wall of the discharging pipe, a certain grinding effect can be achieved on discharged large-particle materials; therefore, the particle size of the material can be reduced, the crushing time of the material in the grading mill main body is shortened, and the production efficiency is improved.
