Suction filtration tank structure for medical intermediates

Abstract

The utility model discloses a suction filtration tank structure for medical intermediates, which comprises a lower tank body and an upper tank body, an annular groove is arranged at the joint of the lower tank body and the upper tank body, a ring body is slidably connected to the annular groove, a through groove rod is connected to the ring body, a motor is mounted at the upper tank body, and the output end of the motor is connected with a turntable. When a solid-liquid mixture in the medical intermediate production process is poured into the upper tank body and is subjected to solid-liquid separation through the filter plate, the motor can be used for driving the turntable to drive the column body to rotate, so that the through groove rod drives the ring body to rotate back and forth in the annular groove, and the filter plate can synchronously rotate along with the ring body; solid impurities accumulated on the filter plate are not easy to attach to pores of the filter plate for a long time due to the movement of the filter plate, and are difficult to stably stay in the pores to form blockage due to the movement of the impurities, so that the pores of the filter plate are kept unblocked, and the filtering efficiency is improved.

Description

Technical Field

[0001] This utility model relates to the technical field of vacuum filtration tanks, and in particular to a structure for a vacuum filtration tank used for pharmaceutical intermediates. Background Technology

[0002] The vacuum filter tank structure for pharmaceutical intermediates is usually a solid-liquid separation device used in the production process of pharmaceutical intermediates. Although the existing vacuum filter tank structure can be applied to the solid-liquid separation operation in the production process of pharmaceutical intermediates, impurities are easily attached to the filter screen during the filtration process. As filtration proceeds, the pores of the filter screen are gradually blocked, which increases the filtration resistance and reduces the filtration efficiency. Frequent replacement or cleaning of the filter screen is required, which increases the complexity and cost of operation. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a filter tank structure for pharmaceutical intermediates.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A filtration tank structure for pharmaceutical intermediates includes a lower tank and an upper tank. An annular groove is formed at the joint between the lower tank and the upper tank. A ring body is slidably connected to the annular groove. A through-groove rod is connected to the ring body. A motor is installed in the upper tank. A turntable is connected to the output end of the motor. A column is connected to the turntable. The column body and the through-groove rod pass through the groove. A filter plate is placed in the annular groove.

[0006] Preferably, the ring body is connected to multiple sets of rods, and the filter plate has multiple sets of holes, with each set of holes movably penetrating through a corresponding rod.

[0007] Preferably, a rubber strip is placed between the lower tank and the upper tank.

[0008] Preferably, the lower tank body has a tapered design at its end.

[0009] Preferably, a valve body is connected to the lower tank body.

[0010] Preferably, the filter plate has a notch.

[0011] Preferably, the lower tank and the upper tank are connected by multiple sets of bolts.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Through the coordination between the lower tank, upper tank, bolts, annular groove, ring, through-groove rod, motor, turntable, column and filter plate, when the solid-liquid mixture in the pharmaceutical intermediate production process is poured into the upper tank and separated by the filter plate, the motor drives the turntable to rotate the column, which in turn drives the through-groove rod to rotate the ring in the annular groove. In this way, the filter plate will also rotate synchronously with the ring. Due to the movement of the filter plate, the solid impurities accumulated on the filter plate will not easily adhere to the pores of the filter plate for a long time. The movement of the impurities makes it difficult for them to remain stably in the pores and form blockages, thereby keeping the pores of the filter plate open and improving the filtration efficiency.

[0014] 2. By using the fit between the filter plate, ring, rod, and hole, and the connection between the hole and the rod, the filter plate can be quickly installed on the ring. This makes it easy to disassemble and clean the filter plate, which is relatively convenient. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5A filtration tank structure for pharmaceutical intermediates includes a lower tank 1 and an upper tank 2. An annular groove 4 is formed at the junction of the lower tank 1 and the upper tank 2. A ring 5 is slidably connected to the annular groove 4 and can rotate within it. A through-groove rod 6 is connected to the ring 5. A motor 7 is installed in the upper tank 2. The model of the motor 7 is selected according to actual working requirements. A turntable 8 is connected to the output end of the motor 7. A column 9 is connected to the turntable 8. The column 9 and the through-groove rod 6 are connected through the through groove. A filter plate 10 is placed in the ring 5. The motor 7 drives the turntable 8 to rotate the column 9. The column 9, in conjunction with the through-groove rod 6, drives the ring 5 to rotate the filter plate 10 reciprocally. In this way, solid impurities on the filter plate 10 can avoid clogging the pores of the filter plate 10, ensuring the separation efficiency of solid-liquid mixtures in the pharmaceutical intermediate production process.

[0023] In this embodiment, multiple sets of rods 11 are connected to the ring body 5, and multiple sets of holes 12 are opened at the filter plate 10. The multiple sets of holes 12 are respectively movably connected to the corresponding rods 11. The connection between the holes 12 and the rods 11 can facilitate the quick disassembly and replacement of the filter plate 10 at the ring body 5. A rubber strip 13 is placed between the lower tank 1 and the upper tank 2. The rubber strip 13 is used to seal the upper tank 2 and the lower tank 1. The lower tank 1 has a tapered design at the end to facilitate liquid discharge. A valve body 14 is connected to the lower tank 1. The valve body 14 can control the flow rate of liquid discharge. A notch is opened at the filter plate 10. The notch is used for the filter plate 10 to contact the connection between the through rod 6 and the ring body 5. The lower tank 1 and the upper tank 2 are connected by multiple sets of bolts 3. The lower tank 1 and the upper tank 2 can be disassembled, so that the ring body 5 can be exposed for disassembly and assembly.

[0024] The working principle of this embodiment is as follows: During use, the solid-liquid mixture from the pharmaceutical intermediate production process is continuously poured into the upper tank 2, and the motor 7 is connected to an external power supply and drive device. The motor 7 can drive the turntable 8 to rotate the column 9. During the movement of the column 9, the through rod 6 will drive the ring 5 to reciprocate. As a result, the filter plate 10 will move synchronously with the ring 5. Because of the reciprocating rotation of the filter plate 10, solid impurities will be prevented from continuously accumulating on the mesh of the filter plate 10, which can ensure the stable operation of solid-liquid separation. The falling liquid will be discharged through the valve body 14.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
