Description

Technical Field

[0001] The utility model relates to a centrifuge, in particular to a centrifuge used for producing 6S-5-methyltetrahydrofolate calcium. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquid and solid particles. In the production of 6S-5-methyltetrahydrofolate calcium salt, a centrifuge is also needed to separate materials. Since 6S-5-methyltetrahydrofolate calcium has very poor stability and is easily oxidized and degraded, it needs to be crystallized before it can be used in the food or pharmaceutical fields. Because 6S-5-methyltetrahydrofolate calcium has very poor stability, a reducing protective agent is often added during the synthesis and preparation process. Therefore, after crystallization, the crystalline powder of 6S-5-methyltetrahydrofolate calcium contains a certain amount of reducing agent, which needs to be washed and centrifuged to obtain a higher purity raw material.

[0003] However, in the prior art, it is often difficult to wash 6S-5-methyltetrahydrofolate calcium salt uniformly when washing the material with a solvent after centrifugation. In addition, the addition of solvent is also easy to dissolve part of the crystalline powder, resulting in clogging of the gaps in the centrifuge filter plate, which makes the centrifugal processing efficiency low. During continuous operation, it is often necessary to stop the machine frequently to wait for the material in the centrifuge to be scraped off and taken out before the next centrifugation operation can be performed. Therefore, we propose a centrifuge for the production of 6S-5-methyltetrahydrofolate calcium salt to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a centrifuge for producing 6S-5-methyltetrahydrofolate calcium in view of the deficiencies in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A centrifuge for producing 6S-5-methyltetrahydrofolate calcium, characterized in that it comprises a shell, a damping shock absorber, an upper cover, a motor, an inner tank turntable, an annular filter plate, a liquid outlet, a liquid inlet, and a washing pipe. The inner tank turntable is rotatably arranged in the shell, the inner tank turntable is rotatably arranged in the shell through a rotating rod, a motor is fixedly arranged on the lower wall of the shell, the rotating rod rotatably penetrates the lower wall of the shell and is connected to the output end of the motor, the inner tank turntable is connected to an annular filter plate, and the inner ring of the annular filter plate is a sawtooth The annular filter plate is connected to the turntable through a connecting mechanism, and the connecting mechanism includes two plug plates, which are symmetrically fixed on the side wall of the annular filter plate at one end close to the inner tank turntable, and two slots corresponding to the plug plates are stacked on the inner tank turntable, and the first springs are fixedly arranged on the inner walls of the two slots, and limiting mechanisms corresponding to the plug plates are arranged in the two slots, a liquid outlet is arranged on the side wall of the shell, and an upper cover is rotatably arranged on the shell, and a liquid inlet and a washing pipe are fixed on the upper cover.

[0007] Preferably, the limiting mechanism includes two card blocks, and the side walls of the two slots are provided with telescopic grooves corresponding to the card blocks. The two card blocks are respectively slidably arranged in the two telescopic grooves, and the two card blocks are connected to the inner walls of the telescopic grooves through second springs. The side walls of the two plug-in plates are provided with card slots corresponding to the card blocks, and the side walls of the two card blocks on one side close to the slot opening are inclined. The two card blocks are provided with corresponding control mechanisms, and the control mechanism includes two levers, and the two levers are respectively fixedly arranged on the side walls of the two card blocks at one end close to the second spring.

[0008] Preferably, a shower head type nozzle is provided on the washing pipe.

[0009] Preferably, the lower end of the washing pipe is bent toward the annular filter plate, and the angle between the center line of the vertical pipe of the washing pipe and the center line of the nozzle outlet pipe is 10-90 degrees.

[0010] Compared with the prior art, the beneficial effect of the utility model lies in that, through the nozzle arranged on the washing pipe, the washing liquid can cover a wider range and be more evenly distributed on the filter cake of the material. In addition, since the inner wall of the annular filter plate is a toothed structure, the total area of ​​the filter surface is increased, making the filtration efficiency more excellent. On the other hand, even if the filtration efficiency is significantly reduced, the card block can be controlled by setting a lever. The card block can be driven to slide out of the slot by toggling the lever, thereby removing the restriction on the plug plate. The annular filter plate can be simply and directly removed from the inner tank turntable and replaced with a new filter plate, thereby greatly improving the centrifugal efficiency.
