Description

Continuous dehydrator

The present invention relates to a continuous dehydrator, especially a dehydrator suitable for medical pharmacy, chemical extraction and food filtration, which can not only obtain the extraction solution or soaking solution to be obtained by dehydration, but also can automatically dehydrate the dehydrator. The dehydrator equipment that automatically removes the material solute residues in it.

The dehydrator can be used in a variety of industries, mainly a kind of solute to be extracted that can release water-soluble components, generate a solution through the action of the solvent, and successfully obtain the required solution through the action of the dehydrator; this This kind of dehydrator is now described by taking the extraction of medicinal juice from traditional Chinese medicine as an example. Please refer to FIG. 10. There is a machine 71, and a dehydration cylinder 90 is arranged on the machine 71, and the dehydration cylinder 90 has an outer cylinder. 91 and the inner cylinder 92, an upper cover 901 is provided above the outer cylinder 91, and a liquid outlet 902 is provided below; Driven by a drive shaft 82 ; a power source 80 is provided on the other side of the machine table 71 , and the main shaft 801 of the power source 80 is driven synchronously with the drive shaft 82 below the inner cylinder 92 via a drive system 81 (eg, a pulley) Therefore, when the main shaft 801 of the power source 80 drives the transmission shaft 82 under the inner cylinder 92 through the transmission system 81, the inner cylinder 92 can be rotated at a high speed in the outer cylinder 91, so that the inner cylinder 92 can be rotated at a high speed due to , so that the drained juice 94 (eg, Chinese herbal medicine juice) is stored under the outer cylinder 91 by centrifugal force, and then the required juice 94 is collected from the liquid outlet 902 of the outer cylinder 91 .

However, in use, the conventional dehydrator equipment is not perfect in design. In actual use, it often has the following shortcomings:

1. Since the conventional inner cylinder 92 and outer cylinder 91 are both U-shaped, it is difficult to remove the filter residue 93 after dehydration, and most of the inner cylinder 92 can be put into the outer cylinder 91 only by using a hanger, and it needs to be poured out. The filter residue 93 also needs to use a spreader, so it is very troublesome to deal with the subsequent cleaning work, which is the main disadvantage.

2. The permeable holes 921 around the inner cylinder 92 are circular, so if the holes are too small, the water permeability will be poor, and if the holes are too large, the filtering effect will be limited, so only moderate holes can be used. Because the diameter of the circular hole will allow many fine residues 931 to pass through and be mixed in the leached juice 94, the leached juice 94 needs to be filtered with a fine mesh again after being collected (not shown in the figure). The subsequent processing is still very troublesome, which is another disadvantage.

3. Since the outer cylinder 91 is fixed on the machine table 71, it is still a very troublesome work to clean, and it is another disadvantage of the conventional design to use a specific tool to wash it.

The main purpose of the present invention is to make the filter mesh body inside the dehydration cylinder into a cone shape, and the dehydration hole into a narrow and long shape, so that when rotating, the filter residue can be automatically discharged out of the dehydration cylinder on the one hand, and the dehydration is also in the process of dehydration. It also has the effect of filtration and achieves the dual purpose of automatic filtration, dehydration and removal of filter residues, which is the characteristic of the present invention.

In order to achieve the above-mentioned purpose, the present invention will be achieved by the following first embodiment: at least include: a dewatering cylinder, a liquid outlet is provided at the bottom, and a hopper is provided above; There is a slag discharge guideway with grooves, the slag discharge guideway is arranged around The inner wall of the dehydration cylinder is rounded, and a slag discharge conduit is connected to protrude out of the dehydration cylinder; it is composed of a rotating main shaft, which is pivotally connected to the bottom of the dehydrating cylinder. , the top of the dewatering net support is fixed under the slag discharge guide rail of the dewatering drum, and the dewatering net support is provided with several longitudinal ribs and transverse ribs on the peripheral side, and a protective cover is arranged below the rotating main shaft. A net body is a conical body, which is placed on the inner side of the dewatering net support, and the net body is provided with several horizontally oriented weft bars, and dense and side-by-side warp bars are arranged between the weft bars, and all warp bars are arranged There is a long and narrow gap between the rods, and the long and narrow gap is parallel to the taper of the net body; a power piece is attached to one side of the dewatering cylinder, and the drive shaft of the power piece is connected with a drive system, and through the drive system It is driven to the rotating main shaft in the center of the dewatering drum, which drives the dewatering net support and the net body to rotate, and dewaters in the dewatering drum. The body is dehydrated by the rotating centrifugal force, but because the mesh body has a taper, it is guided by the centrifugal force and the inner wall of the mesh, so that the filter residue will gradually move up along the inner wall of the mesh when the dehydration becomes lighter, and finally be screwed in The filter residue is discharged into the groove of the slag discharge guide rail, and the filter residue is discharged from the dehydration cylinder by the slag discharge guide, so as to achieve the multiple functions of automatic filtration, dehydration and removal of the filter residue.
