Technical Field
[0001] The utility model relates to the technical field of biological safety devices, in particular to a novel DPTE device. Background Art
[0002] Double Port Transfer Exchange (DPTE) is designed to quickly place or remove products in a closed environment without destroying the closed environment. It is usually used for the safe handling of hazardous materials and has quickly become the most complete and safest transfer system in the chemical, pharmaceutical and biological industries. Biosafety isolators use this device for leak-free transfer of experimental materials, ensuring the effective operation of the biosafety system.
[0003] The DPTE device in the prior art brings some problems in operation. Taking the biosafety isolator as an example, the system uses a locking device to lock each other, completing the locking between the transfer barrel and the barrel door, the barrel flange and the isolator flange, and the barrel door and the isolator box door. When the barrel is connected to the box, the operator must rotate the transfer barrel continuously clockwise to complete the above-mentioned locking process. When disassembling, rotate the barrel counterclockwise to unlock these lockings in turn. This process requires manual labor and is time-consuming and labor-intensive. In particular, the mechanical position of the transfer barrel is deformed after high-temperature sterilization, which increases the difficulty during installation or disassembly.

[0018] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0019] Example 1: Reference Figures 1 to 4As shown, a novel DPTE device comprises: a box flange 3 arranged on a box body 1, a barrel flange 5 arranged at the opening of a transfer barrel 6, and a locking device 9, the locking device being used to connect the box flange and the barrel flange. A box opening is arranged at the center of the box flange, a box door 2 cooperating with the box opening is arranged in the box opening 12, and the opening and closing of the box door can control the opening and closing of the box flange. A barrel opening 11 is arranged at the center of the barrel flange, a barrel door 4 cooperating with the barrel opening is arranged on the barrel opening, and the opening and closing of the barrel door can control the opening and closing of the transfer barrel; a connecting device is arranged on the barrel door and the box door so that the barrel door and the box door can be connected to each other.
[0020] The connection device in this embodiment adopts electromagnetic connection. Specifically, the connection device includes an electromagnet 7 arranged on the box door and an armature 8 arranged on the barrel door. After the electromagnet is energized, a magnetic force is generated. Through the mutual attraction between the magnetic forces, the electromagnet and the armature attract each other, so that the box door and the barrel door are mutually adsorbed and connected.
[0021] In addition, the armature is embedded in the outer end surface of the barrel door, and the electromagnet is embedded in the inner end surface of the barrel door.
[0022] The locking device includes a plurality of electromagnetic locks arranged in the circumferential direction of the box flange, and the electromagnetic locks belong to the prior art. A limiting convex ring 10 is arranged in the outer circumferential direction of the barrel flange. After the barrel flange and the box flange are butted, the vertical axis of the electromagnetic lock is pressed against the limiting convex ring, and the barrel flange and the box flange are tightly connected.
[0023] In this embodiment, six electromagnetic locks are arranged, and the six electromagnetic locks are evenly distributed in the circumferential direction of the box flange. The six electromagnetic locks are arranged so that the electromagnetic locks can act evenly in the circumferential direction of the box flange, so that the box flange and the barrel flange can fit tightly, thereby preventing the transfer barrel and the substances in the box from contacting the outside air.
[0024] The diameter of the box opening of the box body flange gradually decreases from the inside of the box door to the outside of the box door, so that the inner side of the box opening forms a frustum, and correspondingly, the box door is set to be a frustum that matches the box opening.
[0025] The diameter of the barrel opening of the barrel flange gradually increases from the inside of the barrel door to the outside of the barrel door, so that the inner side of the barrel opening forms a frustum shape. Correspondingly, the barrel door is set to be a frustum shape that matches the barrel opening.
[0026] The diameter of the barrel flange close to the outer side of the barrel door is D1, and the diameter of the box flange close to the outer side of the box door is D2, and D2 is greater than or equal to D1.
[0027] The working principle of this embodiment is as follows:
[0028] 1. Under normal conditions, Figure 2 As shown, the box door and the box opening are matched, the box body is in a sealed state, the electromagnet on the box door is in a power-off state, and the electromagnet has no magnetic force. The barrel door and the barrel opening are matched, the transfer barrel is in a sealed state, and the electromagnetic lock is in a closed state.
[0029] 2. If Figure 3 As shown, the barrel flange on the transfer barrel and the box flange on the box body are then aligned so that the box flange and the barrel flange fit tightly together. The electromagnetic lock is then started, and the vertical axis of the electromagnetic lock is pressed against the limiting convex ring, so that the barrel flange and the box body flange are tightly connected.
[0030] 3. If Figure 3 As shown, the electromagnet is started, and the electromagnet generates magnetic attraction and absorbs the armature, so that the barrel door and the box door are tightly fitted to form a joint body.
[0031] 4. If Figure 4 As shown, a sleeve is provided on the box body, and the worker uses the sleeve to manually remove the combination of the box door and the barrel door from the barrel flange and the box body flange, so that the box body and the transfer barrel are combined to form a new sealed body. Then, the materials or utensils in the transfer barrel are transferred through the newly formed channel.
[0032] 5. When the transfer barrel needs to be removed, the worker installs the combination of the box door and the barrel door back to the barrel flange and the box flange through the sleeve, so that the barrel flange and the barrel door are sealed and fitted, and the box flange and the box door are sealed and fitted, and then the electromagnet is turned off to make the magnetic force of the electromagnet disappear, and then the electromagnetic lock is turned off to make the vertical axis of the electromagnetic lock and the limit convex ring separate. Then the transfer barrel can be removed as a whole.
[0033] In the utility model, by setting up a new DPTE device, the efficiency of transferring substances and materials between the box and the transfer barrel can be improved, and in the transfer process, electromagnetic coordination is adopted, thereby eliminating cumbersome operations such as opening and closing doors, reducing the difficulty of operation, and effectively improving the efficiency of operation.
[0034] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
