Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a swing-type granulator for preparing pharmaceutical intermediates. Background Technology

[0002] Oscillating granulators (also known as oscillating pellet mills or oscillating mixers) are widely used in the pharmaceutical industry, especially in the preparation of drug granules during the pharmaceutical manufacturing process. They are commonly used for processing pharmaceutical intermediates (such as raw materials or semi-finished products of drugs), particularly for powdered materials that require granulation. Through the operation of the oscillating granulator, uniform mixing and granulation of drug raw materials can be achieved, thereby improving the performance and quality of the drugs.

[0003] In the prior art, Chinese patent application number 202222375903.0 discloses a pharmaceutical oscillating granulator, including a oscillating granulator main unit, a feed hopper, a sieve frame, a discharge hopper, a connecting cylinder, and a guide pipe. The feed hopper and sieve frame are fixedly connected to the oscillating granulator main unit. The top of the discharge hopper is fixedly connected to the sieve frame, and the connecting cylinder is fixedly connected to the bottom of the discharge hopper. A support plate is fixedly installed on the side of the oscillating granulator main unit, and a material basin is placed on the top of the support plate. The guide pipe contacts the outside of the connecting cylinder, and a square block is fixedly installed on the guide pipe. Short grooves and long grooves are formed on the side of the oscillating granulator main unit, and the short grooves and long grooves are connected. A top hole is formed on the top of the square block, and a sliding hole is formed on the side wall of the top hole. This utility model has the following advantages and effects: it facilitates the loading and unloading of the material basin and allows for quick disassembly and cleaning of the guide pipe.

[0004] However, the above-mentioned technical solutions have the problem that when the oscillating granulator finishes granulation and is ready for collection, the operator needs to turn off the oscillating granulator before the collection box full of granules can be replaced. This makes it impossible to achieve continuous production, affects the production efficiency of pharmaceutical manufacturing, and fails to meet the usage requirements. Therefore, this application proposes an oscillating granulator for preparing pharmaceutical intermediates to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, after granulation, operators need to shut down the granulator before replacing the collection box filled with granules, which prevents continuous production, affects pharmaceutical production efficiency, and fails to meet usage requirements. Therefore, this invention proposes a granulator for preparing pharmaceutical intermediates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gyratory granulator for preparing pharmaceutical intermediates includes a gyratory granulator main unit, a feed hopper, and a sieve frame. The gyratory granulator also includes:

[0008] The top end of the feeding pipe is fixedly connected to the bottom of the sieve frame;

[0009] The base is fixedly installed at the bottom of the main body of the oscillating pellet mill, and the top of the base is provided with an installation groove.

[0010] The moving assembly includes a motor, a lead screw, a nut, and a placement plate. The motor is fixedly installed on the left side of the base. The right end of the lead screw is rotatably connected to the inner wall of the right side of the mounting groove. The left end of the lead screw is fixedly installed on the output shaft of the motor. The nut is threaded onto the lead screw, and the top of the nut is fixedly installed to the bottom of the placement plate.

[0011] Multiple receiving components are provided, and each receiving component is located on top of a corresponding placement plate. The receiving components cooperate with the feeding pipe.

[0012] As a preferred embodiment of this utility model, a solenoid valve is installed on the feeding pipe.

[0013] As a preferred embodiment of this utility model, two sliders are fixedly installed at the bottom of the placement plate, and two sliding grooves are opened at the top of the base, with the sliders slidably connected in the corresponding sliding grooves.

[0014] As a preferred embodiment of this utility model, the receiving assembly includes a material box, a funnel-shaped edge, and two handles. The bottom end of the material box is placed on the top of the placement plate, the bottom end of the funnel-shaped edge is fixedly installed on the top of the material box, and the two handles are fixedly installed on the front and rear sides of the material box, respectively.

[0015] As a preferred embodiment of this utility model, the top of the placement plate is provided with multiple limiting grooves, and the bottom of the material box is placed inside the corresponding limiting groove.

[0016] In a preferred embodiment of this utility model, the inner wall width of the limiting groove is the same as the width of the material box, and there is an interference fit between the material box and the inner wall of the limiting groove.

[0017] Beneficial effects:

[0018] 1. The motor can be started to drive the lead screw to rotate. When the lead screw rotates, it can drive the placement plate to move in position through the threaded connection between the lead screw and the nut. At this time, the placement plate can drive multiple receiving components to move in position so that the multiple receiving components can be aligned with the feed pipe, and the medicine particles can be collected without stopping the machine.

[0019] 2. By setting a funnel-shaped edge on the top of the material box, when multiple material boxes are placed on the top of the placement plate, the tops of the multiple material boxes fit together, avoiding leakage of medicine when switching. In addition, the handle makes it easy for personnel to move the material boxes.

[0020] This invention, through its simple structure, enables the replacement of the granulation bin without shutting down the main unit of the oscillating granulator, thus achieving continuous production, improving pharmaceutical production efficiency, meeting usage requirements, and demonstrating strong practicality.
