Dry extract powder collecting device for spray dryer special for traditional Chinese medicine extract

Abstract

The utility model discloses a dry extract powder collecting device for a spray dryer special for traditional Chinese medicine extract. The dry extract powder collecting device comprises a rigid and non-deformable birdcage; the PE bag is detachably sleeved and wrapped at the bottom and the outer periphery of the birdcage, and the birdcage forms rigid support in the PE bag. The birdcage comprises vertical rigid rods, a rigid ring and a plate frame, the rigid ring fixedly wraps the vertical rigid rods in an annular array to form the birdcage, and the plate frame is fixed to the bottoms of the vertical rigid rods. The rigid and non-deformable birdcage forms a rigid support in the PE bag to prevent the soft PE bag from being reversely sucked in under the negative pressure environment of the connector of the material collector, and the sealing of the quick-assembly connector avoids the situation that dry paste powder in the PE bag is exposed to the external environment, so that the moisture content of part of varieties easy to absorb moisture is unqualified. The problem that in the prior art, a soft PE bag can be directly sucked in the reverse direction is solved.

Description

Technical Field

[0001] The utility model relates to a device for collecting dry paste powder of a special spray dryer for traditional Chinese medicine extract, belonging to the technical field of medicine production devices. Background Art

[0002] The spray dryer specially used for Chinese medicine extract has a cyclone receiver (see Chinese patent publication number CN212594045U).

[0003] During the powder collection process, the PE bags need to be tied to the receiver. Since the spray dryer for Chinese medicine extract needs to maintain a negative pressure state during operation, there is a possibility that the soft PE bags will be sucked back.

[0004] The existing technology is to reserve a small hole when bundling the PE bag so that the inside of the PE bag is connected to the external environment to provide air to avoid reverse inhalation by the negative pressure environment. However, this operation will cause the dry paste powder in the PE bag to be exposed to the external environment for a long time, causing the moisture content of some moisture-absorbing varieties to be unqualified. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a device for collecting dry paste powder of a special spray dryer for traditional Chinese medicine extract.

[0006] The utility model is realized through the following technical solutions.

[0007] The utility model provides a device for collecting dry paste powder of a spray dryer for Chinese medicine extract, comprising:

[0008] A device that provides rigid support inside the PE bag.

[0009] Includes: a rigid, non-deformable bird cage;

[0010] The soft PE bag can be removably put on and wrapped around the bottom and outer periphery of the bird cage, and the bird cage forms a rigid support inside the PE bag.

[0011] The bird cage comprises a vertical rigid rod, a rigid ring and a plate frame. The rigid ring is fixedly wrapped around the outside of a plurality of vertical rigid rods in an annular array to form the bird cage, and the plate frame is fixed at the bottom of the vertical rigid rod.

[0012] The vertical rigid rod, rigid ring and plate frame are all made of stainless steel.

[0013] It also includes a quick-release interface; the quick-release interface is formed by two conical stainless steel plates being contacted and pressed together, and the two conical stainless steel plates press the mouth of the PE bag for subsequent docking.

[0014] The beneficial effects of the utility model are as follows: the rigid and non-deformable bird cage forms a rigid support inside the PE bag to prevent the soft PE bag from being reversely sucked in under the negative pressure environment of the receiving device interface, and the sealing of the quick-release interface prevents the dry paste powder in the PE bag from being exposed to the external environment, causing the moisture content of some moisture-absorbing varieties to be unqualified, thereby solving the problem of the prior art that the soft PE bag will be directly sucked in reverse.

[0018] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0019] like Figure 1 to Figure 2 shown.

[0020] The present application discloses a device for collecting dry paste powder of a spray dryer for Chinese medicine extract, comprising:

[0021] A rigid and non-deformable bird cage 1 is formed by a vertical rigid rod 11 and a rigid ring 12 fixedly wrapped around the outside of a plurality of vertical rigid rods 11 in an annular array. A plate frame 13 is provided at the bottom of the bird cage 1 to limit the PE bag 2 from axial suction displacement. The vertical rigid rod 11, the rigid ring 12 and the plate frame 13 are all made of stainless steel.

[0022] It also includes a PE bag 2 that wraps the bottom and periphery of the bird cage 1. The PE bag 2 can be detachably inserted and wrapped around the bottom and periphery of the bird cage 1. The mouth of the PE bag 2 is fastened and fixed on the bird cage 1 for collecting pollen with a rubber band.

[0023] It also includes a quick-install interface 3 formed by contacting and pressing two conical stainless steel plates. The quick-install interface 3 is conical and presses the PE bag 2 to seal it. The quick-install interface 3 is connected to the receiver interface 4 in a conical quick-install sealing manner.

[0024] The PE bag 2 is inserted and wrapped around the bottom and outer periphery of the bird cage 1. The PE bag 2 and the bird cage 1 are sealed and connected through the quick-release interface 3 and the receiver interface 4. The dry paste powder 41 is in the space of the PE bag 2 opened by the bird cage 1. Since the bird cage 1 is rigid and cannot be deformed, the bird cage 1 forms a rigid support inside the PE bag 2 to prevent the soft PE bag 2 from being reversely sucked in under the negative pressure environment of the receiver interface 4. The sealing of the quick-release interface 3 prevents the dry paste powder in the PE bag 2 from being exposed to the external environment, causing the moisture content of some moisture-absorbing varieties to be unqualified, thereby solving the problem of the prior art that the soft PE bag will be directly sucked in reverse.

[0025] After the dry paste powder 41 is attached to the inner wall of the soft PE bag 2, the PE bag 2 is softened and deformed and removed from the bird cage 1, which is more convenient than using a purely rigid barrel that needs to be knocked and vibrated to collect powder.
