Abstract
Description
Technical Field
[0001] This utility model relates to a sterilization device for the production of empty capsules, and more particularly to a sterilization device based on cobalt-60 irradiation. Background Technology
[0002] After the production of empty capsules is completed, sterilization is required. Currently, common manufacturers place many empty capsules in storage baskets, then place these baskets into an ultraviolet (UV) irradiation chamber for sterilization. However, this UV irradiation method is time-consuming due to the low energy of UV light. Furthermore, because the capsules are stacked together and UV light penetration is weak, some capsules do not receive adequate sterilization, resulting in poor overall sterilization. Therefore, existing sterilization equipment for empty capsule production suffers from poor sterilization efficiency. Utility Model Content
[0003] The purpose of this invention is to provide a cobalt-60 irradiation sterilization device. This invention has the advantage of good irradiation sterilization effect.
[0004] The technical solution of this utility model: A cobalt-60 irradiation sterilization device includes a sterilization chamber, on which multiple evenly distributed cobalt-60 irradiation sources are arranged on each inner side wall; a partition is provided on the inner bottom surface of the sterilization chamber, on which multiple evenly distributed air outlets are provided, and on each air outlet are multiple radially distributed guide components; multiple evenly distributed main air ducts are arranged between the partition and the inner bottom surface of the sterilization chamber, and each main air duct is provided with multiple branch air ducts for blowing air out of the air outlets; utilizing the main air ducts and The blower branch pipe can blow air into each air outlet. With the guide components set on the air outlet, the air blown out of the air outlet has a certain rotation effect. This rotation effect can then blow the hollow capsules around the air outlet upward and make them rotate. Combined with the cobalt-60 irradiation source set on each inner wall, the hollow capsules can be irradiated and sterilized in all directions. This prevents the hollow capsules from being unable to be properly irradiated and sterilized due to accumulation, thus ensuring the sterilization effect.
[0005] In the aforementioned cobalt-60 irradiation sterilization equipment, a transparent protective cover is provided on the inner wall of the sterilization chamber at the position corresponding to each cobalt-60 irradiation source; the transparent protective cover can protect the cobalt-60 irradiation source inside and extend its service life.
[0006] In the aforementioned cobalt-60 irradiation sterilization equipment, the side of the transparent protective cover is rounded. The rounded side of the transparent protective cover is to avoid sharp edges, which could cause damage or deformation of the empty capsules during the irradiation sterilization process. This reduces unnecessary product damage and lowers production costs.
[0007] In the aforementioned cobalt-60 irradiation sterilization equipment, a support member is provided on the bottom surface of the partition corresponding to one side of each air outlet, and the bottom end of each support member is fixedly installed on the bottom surface of the sterilization chamber; a fixing seat for fixing the blower branch pipe is provided on the side of each support member, and a through hole for the blower main pipe to pass through each support member; the support member not only supports the partition and improves the load-bearing capacity of the partition, but also the fixing seat for fixing the blower branch pipe on the side of each support member can fix and support the blower branch pipe, thereby ensuring the stability of the overall structure.
[0008] In the aforementioned cobalt-60 irradiation sterilization device, a buffer layer is laid on the top surface of the partition, and through holes are provided on the buffer layer at the position corresponding to each air outlet; the buffer layer can reduce the collision damage between the hollow capsule and the partition, further reducing production costs.
[0009] In the aforementioned cobalt-60 irradiation sterilization equipment, an inspection port is provided on the side wall of the sterilization chamber, and an inspection door is rotatably installed on the inspection port. A sealing ring is provided on the inspection door at the position corresponding to the inspection port. The rotatable inspection door facilitates the removal and placement of the internal hollow capsule and the maintenance of the internal cobalt-60 irradiation source, thus simplifying maintenance.
[0010] In the aforementioned cobalt-60 irradiation sterilization device, the top surface of the partition is a downward-concave arc surface. By setting the top surface of the partition to a downward-concave arc surface, the hollow capsules can automatically move towards the center, avoiding the hollow capsules from staying on the side and being unable to perform good irradiation sterilization, thus ensuring the irradiation sterilization effect.
[0011] Compared with existing technologies, this invention improves the existing sterilization equipment for hollow capsule production. By installing multiple cobalt-60 irradiation sources on each inner wall of the sterilization chamber, it can achieve all-round sterilization of the hollow capsules placed inside the sterilization chamber. By setting up partitions, air outlets, a main air pipe, and branch air pipes, the main air pipe and branch air pipes can blow air to each air outlet. With the guide components set on the air outlets, the air blown out of the air outlets has a certain rotation effect. This rotational air blows the hollow capsules around the air outlet upwards and causes them to rotate. This allows the cobalt-60 irradiation sources to irradiate and sterilize the hollow capsules from all sides, preventing the phenomenon of hollow capsules being unable to receive adequate irradiation and sterilization due to accumulation, thus ensuring the sterilization effect. Furthermore, this invention also features transparent protective covers on the inner wall of the sterilization chamber corresponding to each cobalt-60 irradiation source. These covers protect the cobalt-60 irradiation sources, preventing damage from collisions between the hollow capsules and the irradiation sources during sterilization, thus extending the product's lifespan. The rounded sides of the protective covers prevent sharp edges that could damage or deform the capsules during sterilization, reducing unnecessary product damage and lowering production costs. Multiple support members on the bottom surface of the partitions not only support the partitions but also enhance their load-bearing capacity. Furthermore, each support component has a mounting base on its side for fixing the blower branch pipe, thus securing the blower branch pipe and ensuring the stability of the overall structure. A buffer layer is laid on the top surface of the partition, reducing collision damage between the hollow capsule and the partition, further lowering production costs. Inspection ports, doors, and sealing rings are provided on the side walls of the sterilization chamber. The rotating inspection door facilitates the removal and placement of the internal hollow capsules and the maintenance of the internal cobalt-60 irradiation source, simplifying maintenance. The top surface of the partition is designed as a downward-concave arc, allowing the hollow capsules to automatically move towards the center, preventing them from remaining on the sides and hindering effective irradiation sterilization, thus ensuring the sterilization effect. Therefore, this invention not only improves the irradiation sterilization effect but also has the advantages of long service life, low production cost, high structural stability, and ease of use.

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0017] Example. A cobalt-60 irradiation sterilization device, configured as follows: Figures 1 to 3 As shown, the device includes a sterilization chamber 1, on which multiple cobalt-60 irradiation sources 2 are evenly distributed on each inner side wall; a partition 3 is provided on the inner bottom surface of the sterilization chamber 1, on which multiple air outlets 4 are evenly distributed, and on each air outlet 4 are multiple radially distributed guide elements 5; multiple evenly distributed blower mains 6 are provided between the partition 3 and the inner bottom surface of the sterilization chamber 1, and on each blower main 6 are multiple blower branch pipes 7 for blowing air out of the air outlets 4.
[0018] A transparent protective cover 8 is provided on the inner wall of the sterilization chamber 1 at the position corresponding to each cobalt-60 irradiation source 2; the side of the transparent protective cover 8 is arc-shaped; a support member 9 is provided on the bottom surface of the partition 3 at the position corresponding to one side of each air outlet 4, and the bottom end of each support member 9 is fixedly installed on the bottom surface of the sterilization chamber 1; a fixing seat 10 for fixing the blower branch pipe 7 is provided on the side of each support member 9, and a through hole for the blower main pipe 6 to pass through is provided on each support member 9; a buffer layer 11 is laid on the top surface of the partition 3, and a through hole is provided on the buffer layer 11 at the position corresponding to each air outlet 4; an inspection port is provided on the side wall of the sterilization chamber 1, and an inspection door 12 is rotatably installed on the inspection port, and a sealing ring is provided on the inspection door 12 at the position corresponding to the inspection port; the top surface of the partition 3 is a downwardly concave arc surface.
[0019] Working Principle: During operation, first connect the entire device to an external safe mains power supply. Then, open the inspection door 12 and place the hollow capsules requiring irradiation sterilization into the sterilization chamber 1 through the inspection port. Next, close the inspection door 12. Then, turn on the cobalt-60 irradiation source 2 and control the external blower to input airflow into the main air duct 6. After the cobalt-60 irradiation source 2 is powered on, it will irradiate the sterilization chamber 1 with irradiation energy (the cobalt-60 irradiation source 2 contains cobalt-60, which is cobalt-60 gamma rays, possessing high energy and penetrating power), thereby irradiating and sterilizing the internal hollow capsules. Simultaneously, the external blower blows air... After airflow is injected into the main pipe 6, this airflow will be diverted into the blower branch pipe 7, and then blown towards the air outlet 4 to the maximum extent through the blower branch pipe 7. When the airflow passes through the air outlet 4, it will generate an outward flow direction under the action of the guide 5, so that the airflow changes from vertical flow to rotational upward. Under the action of this rotation, the hollow capsules around the air outlet 4 can be blown upward and rotated at the same time, so that all surfaces of the hollow capsules can come into contact with the cobalt-60 gamma rays generated by the cobalt-60 irradiation source 2, thereby completing the all-round irradiation sterilization of the hollow capsules and ensuring the sterilization effect.
