[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0033] See attached Figure 1-4 The present embodiment is a pharmaceutical intermediate system standby extraction device, comprising an extraction barrel 100, a pulse generator 200 and a base frame 300. The extraction barrel 100 is mounted on the base frame 300. The extraction barrel 100 is provided with a pulse generator 200. The pulse generator 200 comprises a C-type tube 210, a liquid pump 220, a flushing assembly 240 and a water inlet assembly 230. Both ends of the C-type tube 210 are inserted into the extraction barrel 100. The liquid pump 220 is mounted in the middle of the C-type tube 210. The liquid pump 220 is connected to the extraction barrel 100 through a C-type tube 210. The inlet draws liquid from one end of the extraction barrel 100 and re-delivers it to the extraction barrel 100 through the outlet at the other end of the C-tube 210. The water inlet component 230 is installed on the inlet, and the flushing component 240 is installed on the outlet. This design structure uses the pulse generator 200 to circulate and flush the liquid in the extraction barrel 100, so that the liquid in the extraction barrel 100 vortexes, accelerates the extraction process, and achieves a better extraction effect. The barrel cover of the extraction barrel 100 can be provided with a stirring motor for internal stirring, which is not limited here.

[0034] The water inlet assembly 230 of this embodiment includes a first mounting arc plate 231, a second mounting arc plate 232 and a filter screen cover 233. The inner wall of the extraction barrel 100 is symmetrically mounted with clamps, and the inlet of the C-type tube 210 is inserted between the symmetrical clamps. The first mounting arc plate 231 is connected to one end of the second mounting arc plate 232, and the other end is connected through the filter screen cover 233. The first mounting arc plate 231 is mounted on the clamp. With this design structure, the liquid in the extraction barrel 100 enters the C-type tube 210 through the water inlet assembly 230, wherein the impurities and other solid particles in the extraction barrel 100 are filtered by the filter screen cover 233 to avoid entering the C-type tube 210. It should be noted that the entry of a small amount of smaller particles will not have any effect.

[0035] The flushing assembly 240 of this embodiment includes a flushing pipe 241, one end of which is connected to the C-tube 210, and the other end is provided with a cutout, and a triangular piece is provided at the cutout for diversion. This design structure allows the liquid flushed from the C-tube 210 to be sprayed out through the flushing pipe 241 and hit the triangular piece for diversion, so that the vortex effect of driving the liquid in the extraction barrel 100 is better.

[0036] The extraction barrel 100 of this embodiment is provided with a plurality of pulse generators 200, which are arranged vertically along the central axis of the extraction barrel 100, and the liquid in the C-tubes 210 of the upper and lower adjacent pulse generators 200 flows in the same direction, so that the overall vortex effect is better.

[0037] The substance extracted in the extraction barrel 100 of the present embodiment is a pharmaceutical intermediate. When the extracted substance is a pharmaceutical intermediate, the barrel cover of the extraction barrel 100 is not provided with a stirring motor to prevent the stirring shaft of the stirring motor from damaging the pharmaceutical intermediate and causing it to release substances that do not need to be extracted. The structure of the present design accelerates the extraction by driving the liquid vortex, does not damage the pharmaceutical intermediate, and has a good effect.

[0038] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
