Description

Technical Field

[0001] This utility model relates to the field of drug synthesis technology, and in particular to an apparatus for synthesizing p-hydroxyacetophenone. Background Technology

[0002] p-Hydroxyacetophenone, commonly known as azadirachtin, is a white needle-like crystal at room temperature. It is flammable, readily soluble in hot water, methanol, ethanol, ether, acetone, and benzene, but sparingly soluble in petroleum ether. It can be used to manufacture choleretic drugs and as a raw material for other organic synthesis. p-Hydroxyacetophenone requires a synthesis apparatus for synthesis, but after the existing synthesis apparatus is used, a small amount of residual drug remains on its inner wall, which is inconvenient to clean.

[0003] To address the aforementioned technical problems, a patent document with publication number (CN210700104U) discloses a synthesis apparatus for p-hydroxyacetophenone, comprising a synthesis chamber, a phenol feed pipe, an acetyl chloride feed pipe, a second sleeve rod, a first sleeve rod, a connecting block, and a brush, among other components. The inner surface of the synthesis chamber is coated with an anti-corrosion material layer. A phenol feed pipe is fixedly fitted to the bottom left side of the synthesis chamber, and a first controller is detachably mounted on the surface of the phenol feed pipe. An acetyl chloride feed pipe is fixedly fitted to the left side of the synthesis chamber, and a second controller is detachably mounted on the surface of the acetyl chloride feed pipe. A second sleeve rod is movably fitted to one side of the first sleeve rod, and the two sleeve rods are rubbed together. A connecting block is fixedly mounted on one side of the second sleeve rod, and a brush is fixedly mounted on one side of the connecting block. This invention achieves the effect of removing residual drug from the inner wall of the synthesis apparatus by configuring the cooperation between the first sleeve rod, the second sleeve rod, and the brush.

[0004] However, in the aforementioned prior art, the brush can only rotate, which prevents it from making full contact with the inner wall of the synthesis box, thus affecting the cleaning effect. Utility Model Content

[0005] The purpose of this invention is to provide a device for synthesizing p-hydroxyacetophenone, which aims to solve the technical problem in the prior art where the brush can only rotate, resulting in it not being able to fully contact the inner wall of the synthesis box, thus affecting the cleaning effect.

[0006] To achieve the above objectives, this utility model employs a synthesis apparatus for p-hydroxyacetophenone, comprising a synthesis tank and a synthesis mechanism. The synthesis mechanism includes a first motor, a rectangular rod, a sliding plate, multiple connecting rods, a circular ring, multiple scrapers, two feed valves, a discharge valve, a cleaning assembly, and a lifting assembly. The first motor is disposed on the upper surface of the synthesis tank, the sliding plate is disposed inside the synthesis tank, the rectangular rod passes through the sliding plate and is slidably connected to the sliding plate, one end of the rectangular rod is fixedly connected to the cleaning assembly, and the other end of the rectangular rod is fixedly connected to the output end of the first motor. One end of each of the multiple connecting rods is fixedly connected to the sliding plate, and the other end of each of the multiple connecting rods is fixedly connected to the circular ring. Multiple scrapers are all fixedly connected to the circular ring and are respectively located on the outside of the circular ring. The lifting assembly is disposed on the outside of the synthesis tank, both feed valves are disposed on the outside of the synthesis tank, and the discharge valve is disposed at the bottom of the synthesis tank.

[0007] The cleaning assembly includes a disc, two fixed rods, and two scrapers. The disc is fixedly connected to the rectangular rod and located at the lower end of the rectangular rod. One end of each of the two fixed rods is fixedly connected to the disc, and the other end of each of the two fixed rods is fixedly connected to the two scrapers.

[0008] The lifting assembly includes a mounting frame, a lifting plate, a lead screw, a second motor, and a connector. The mounting frame is fixedly connected to the outside of the synthesis tank. The lead screw passes through the lifting plate and is threadedly engaged with the lifting plate. Both ends of the lead screw are rotatably connected to the mounting frame. The output end of the second motor is fixedly connected to the lead screw. The connector is fixedly connected to the lifting plate.

[0009] The connecting component includes a connecting frame, an annular slide rail, and two sets of supporting components. The connecting frame is fixedly connected to the lifting plate, the annular slide rail is fixedly connected to the ring and located on the upper surface of the ring, and the two sets of supporting components are slidably connected to the annular slide rail.

[0010] Each set of support components includes a sliding sleeve and a round rod. The sliding sleeve is slidably connected to the annular slide rail, and the round rod passes through the synthesis tank and is slidably connected to the synthesis tank. One end of the round rod is fixedly connected to the sliding sleeve, and the other end of the round rod is fixedly connected to the connecting frame.

[0011] This invention discloses a synthesis apparatus for p-hydroxyacetophenone. A rectangular rod passes through and is slidably connected to a sliding plate. One end of the rectangular rod is fixedly connected to a cleaning assembly, and the other end is fixedly connected to the output end of a first motor. Multiple scrapers are fixedly connected to a circular ring. In actual use, phenol and acetyl chloride are added to the synthesis tank through two feed valves to carry out the synthesis reaction. The first motor is started, and its output end drives the rectangular rod to rotate. The rectangular rod drives the sliding plate to rotate, which in turn drives multiple connecting rods to rotate. These connecting rods then drive the circular ring to rotate, thereby stirring the raw materials. After synthesis, the discharge valve is opened to discharge the synthesized p-hydroxyacetophenone and residue from the synthesis tank. Then, the first motor drives the rectangular rod to continue rotating, which in turn drives the cleaning assembly to rotate, thereby cleaning the inner bottom surface of the synthesis tank. The ring drives multiple scrapers to rotate, while the lifting assembly drives the ring to move up and down, which in turn drives the multiple scrapers to move up and down. This allows the scrapers to move up and down while rotating, thereby cleaning the residue on the inner wall of the synthesis tank. This method effectively solves the problem in the prior art where the brush can only rotate, preventing it from fully contacting the inner wall of the synthesis tank and thus affecting the cleaning effect.
