Description

New type pill air separation equipment

technical field

The invention relates to a wind separation device, in particular to a new type of air separation equipment for pills.

Background technique

With the rapid development of the Chinese patent medicine pharmaceutical industry, the quality requirements for medicines within the industry are also constantly improving. In the collision light process of pills, the original process is water collision pills. In this process, the collision method is changed to dry collision due to the occurrence of flower balls in the pills. After dry bumping, the following problems were found with the pills:

1. Part of the medicinal powder is attached to the finished pill, which causes the finished pill to enter the medicine bag together with the medicinal powder during the sub-packaging process, or partially stay at the seal, which affects the packaging quality, the quality of the medicine packaging and the appearance of the pill.

2. Part of the powder is flying in the environment, causing the whole environment to be harsh, resulting in (1) an increase in the occupational health risk rate of operators; (2) the vacuum feeder head has a short service life, and according to statistics, about 10 pieces are damaged every year; (3) ) The clearance time is long and the production efficiency is low.

3. In the process of pill selection, incomplete hemispherical or other shaped special-shaped pills may occasionally appear in the finished dry pills, resulting in a very small part of the finished pills may enter the medicine bag and a very small part of the card during the sub-packaging process The pill counting board cannot enter the medicine bag, which affects the weight difference and the appearance of the pills.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a solution to the above problems, to solve the problem that the powder is attached to the finished pill during the wind selection, or is flying in the environment, and the special-shaped pill is stuck on the pill counting board and cannot enter the medicine bag, which affects the weight difference. A new type of pill winnowing and separation equipment for quality and pill appearance problems.

In order to achieve the above purpose, the technical solution adopted in the present invention is as follows: a new type of pill air separation and separation equipment, including a frame, also includes a vacuum feeder, an inner pipe body, an outer pipe body and a negative pressure fan;

The vacuum feeding machine is arranged on the frame, the inner pipe body is arranged obliquely below the frame, and the upper end of the inner pipe body is communicated with the discharge port of the vacuum feeding machine, and the side wall of the inner pipe body is uniform and uniform along its cross section. Staggered distribution of strip holes, the width of the strip holes is smaller than the diameter of the air-selected pills;

The outer pipe body is a semi-circular pipe, which is coaxially arranged below the outer side of the inner pipe body, and a fan interface is arranged on the outer wall of the outer pipe. .

Preferably, a dust collection bag is provided at the air outlet of the negative pressure fan.

Preferably, the fan interface is close to the upper end of the outer pipe body.

Preferably: the diameter of the pill is 4mm, the width of the strip hole is 2.5mm, and the length is 5mm.

Preferably: the inner pipe body and the outer pipe body are made of stainless steel, and the upper surface of the inner pipe body is close to the bottom, and there is an opening for checking and cleaning slag, and the opening is provided with a matching door body, so The outer tube body does not affect the opening and closing of the door body.

Compared with the prior art, the advantages of the present invention are: the vacuum feeder lifts the pills and the medicinal powder in the space height, the negative pressure fan generates a negative pressure to assist the separation of the pills and the medicinal powder by the strip holes on the inner pipe body, and the inner pipe The length of the body strip hole is not limited, and the width should be smaller than the diameter of the complete pill, evenly staggered distribution, to ensure that each pill can pass through the strip hole in the process of sliding and rolling, effectively separating the pill from the powder. The outer tube body and the inner tube body form a jacket. When semi-circular pills, special-shaped pills, etc. appear in production, these pills can be effectively separated from the jacket through the strip holes.

Because the invention can realize the effective separation of finished pills and medicinal powder, can greatly reduce the environmental dust concentration, reduce the occupational health risk of operators, prolong the life of the head of the vacuum feeder, reduce the number of special-shaped pills in the sub-packaging process, and reduce the inclusions in the finished small bags. and reduce the quality risk of horizontal sealing caused by inclusion of medicinal powder.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings.

Embodiment 1: Referring to Figure 1, a new type of pill air-selecting and separating equipment includes a rack 1 and a vacuum feeder 2, an inner pipe body 3, an outer pipe body 4 and a negative pressure fan 6;

The vacuum feeder 2 is arranged on the frame 1, the inner tube body 3 is arranged obliquely below the frame 1, and the upper end of the inner tube body 3 is communicated with the discharge port of the vacuum feeder 2, and the side of the inner tube body 3 is connected. The wall is uniformly and staggeredly distributed with strip holes 5 along its cross section, and the width of the strip holes 5 is smaller than the diameter of the air-selected pills;

The outer pipe body 4 is a semi-circular pipe, which is coaxially arranged below the outer side of the inner pipe body 3. The outer wall of the outer pipe body 4 is provided with a fan interface. The fan interface is connected with the air inlet of the negative pressure fan 6, and the air outlet of the negative pressure fan 6 towards the side of rack 1.

In this embodiment, a dust bag is provided at the air outlet of the negative pressure fan 6; the fan interface is close to the upper end of the outer pipe body 4; the diameter of the pill is 4 mm, the width of the strip hole 5 is 2.5 mm, and the length is 5mm.

The inner pipe body 3 and the outer pipe body 4 are all made of stainless steel, and the upper surface of the inner pipe body 3 is close to the bottom, and there is an opening for checking and cleaning slag, and the opening is provided with a matching door body 7, The outer tube body 4 does not affect the opening and closing of the door body 7 . In this embodiment, the size of the opening is 100×150 mm, and both sides of the opening are flush with both sides of the outer tube body 4 , so that the opening can be made as large as possible without affecting the opening and closing of the door body 7 .

The working principle of the present invention is as follows: the vacuum feeder 2 lifts the pills and the medicinal powder in the space height, the pills and the medicinal powder enter the inner tube body 3 through the discharge port after being lifted, and slide down along the inner wall of the inner tube body 3 under the action of gravity . When sliding down, it will pass through the strip hole 5. Since the width of the strip hole 5 is smaller than the diameter of the selected pill, the complete pill will not pass through the strip hole 5, but will slide out from the lower end along the inner tube body 3. . The powder that is not round enough, incomplete, and small particles will pass through the strip hole 5 and be located in the gap between the inner tube body 3 and the outer tube body 4. At this time, the negative pressure fan 6 generates negative pressure, which will reduce the weight of the powder. The powder or the extremely small incomplete pills are sucked into the negative pressure fan 6 and discharged from the air outlet, but cannot be sucked away by the negative pressure fan 6, and the special-shaped pills whose size is smaller than the width of the strip hole 5, then follow the inner pipe. The gap between the body 3 and the outer tube body 4 slides down from the bottom of the gap. At this point, the classification of pills, powders, and special-shaped pills can be completed, and the staff only needs to set up a collection device at the corresponding position.

The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the protection of the present invention. within the range.
