Description

Technical Field

[0001] The utility model relates to the technical field of biological safety cabinets, in particular to a biological safety cabinet with waste treatment function. Background Art

[0002] A biological safety cabinet is a box-type air-purifying negative-pressure safety device that can prevent the escape of aerosols containing certain dangerous or unknown biological particles during experimental operations. It is widely used in scientific research, teaching, clinical testing and production in the fields of microbiology, biomedicine, genetic engineering, and biological products. It is the most basic safety protection equipment in the first-level protection barrier of laboratory biosafety.

[0003] The existing biosafety cabinet mainly sucks the air inside the cabinet outward to keep the cabinet in a negative pressure state, and protects the staff through vertical airflow. Since the waste liquid generated after the use of the biosafety cabinet needs to be manually cleaned by the staff, the waste generated by the biosafety cabinet comes into secondary contact with the environment and the staff. Since the waste liquid carries a small amount of harmful substances, the harmful substances in the waste will leak, which reduces the safety of the staff's operation of the biosafety cabinet. Therefore, the existing biosafety cabinet needs to be improved to a certain extent. Utility Model Content

[0027] See also Figure 1-4 The utility model provides a technical solution: a biological safety cabinet with waste treatment, the outer wall of the transmission rod 12 is fixedly connected to the first adjustment plate 13, and the two ends of the No. 1 adjustment plate 13 are fixedly connected to the first bearing rod 14, the outer wall bearing of the No. 1 bearing rod 14 is connected to a connecting rod 15, and the other end of the connecting rod 15 is movably connected to a No. 2 bearing rod 16, the outer wall of the No. 2 bearing rod 16 is fixedly connected to the second adjustment plate 17, and one side of the No. 2 adjustment plate 17 is fixedly connected to a support frame 21, and the inner wall of the support frame 21 is installed with a hanging ring 22.

[0028] The two ends of the connecting rod 15 are fixedly connected with a No. 1 bearing rod 14 and a No. 2 bearing rod 16, and the No. 1 bearing rod 14 forms an adjustment structure through the connecting rod 15 and the No. 2 bearing rod 16, and the No. 1 adjustment plate 13 forms a rotating structure through the No. 1 bearing rod 14 and the transmission rod 12;

[0029] There are two connecting rods 15 and two second adjusting plates 17, and the two connecting rods 15 and the second adjusting plates 17 are symmetrically arranged with the transmission rod 12 as the symmetry point. The two second adjusting plates 17 form a relative motion structure with the first adjusting plate 13 through the connecting rods 15;

[0030] The outer wall of the hanging ring 22 is movably connected to the limiting rod 23, and the limiting rod 23 forms a rotating structure through the hanging ring 22. The outer wall of the limiting rod 23 is fixedly connected to a return spring 24, and the other end of the return spring 24 is fixedly connected to the hanging ring 22. The return spring 24 forms a compression structure with the hanging ring 22 through the limiting rod 23.

[0031] The specific implementation method is as follows: by setting a limit rod 23 and a return spring 24, a squeeze-engagement and spring return method is adopted. Since the limit rod 23 is rotated along the hanging ring 22 by the thrust of the pull ring 4, the limit rod 23 compresses the return spring 24, thereby the pull ring 4 is sleeved on the outer wall of the hanging ring 22, and then the return spring 24 rebounds to drive the limit rod 23 to contact the hanging ring 22, completing the closure of the pull ring 4, thereby facilitating the staff to quickly replace the waste collection belt, improving the staff's subsequent waste collection efficiency, and preventing the collection bag 3 from falling off when being closed, thereby ensuring the stability of the overall device in waste collection and increasing the practicality of the overall device.

[0032] Working principle: When using the biological safety cabinet for waste treatment, firstly, the collection bag 3 is sleeved on the inner wall of the filling barrel 2, and then the inner wall of the collection bag 3 is penetrated and connected with the pull ring 4 to contact the limiting rod 23. At this time, the limiting rod 23 is forced to rotate along the hanging ring 22, so that the limiting rod 23 compresses the reset spring 24, thereby sleeves the pull ring 4 on the outer wall of the hanging ring 22, and then the reset spring 24 rebounds and drives the limiting rod 23 to contact the hanging ring 22, completing the closure of the pull ring 4;

[0033] Then the staff puts the object to be tested into the biosafety cabinet body 5, and the harmful gas generated by the experimental object is filtered and discharged through the biosafety cabinet body 5, and then the harmful substances retained are disinfected and cleaned through the biosafety cabinet body 5. At this time, the waste liquid generated after disinfection flows into the discharge pipe 8 through the filter plate 6 and the lower bin 7, so that the waste liquid is heated inside the lower bin 7, and the secondary disinfection of the waste liquid is completed, and then the waste liquid is transported to the collection bag 3 through the discharge pipe 8;

[0034] Then, the cylinder 20 is started, and the cylinder 20 is telescopically adjusted through the fixed plate 11, so that the cylinder 20 rotates along the fixed frame 18 through the bearing ring 19, and at the same time, the cylinder 20 pushes the second adjustment plate 17 through the bearing ring 19 and the fixed frame 18, so that the connecting rod 15 is stretched through the second bearing rod 16 fixed on one side of the second adjustment plate 17, and then the first bearing rod 14 fixed on one side of the connecting rod 15 pulls the first adjustment plate 13;

[0035] At this time, the No. 1 adjustment plate 13 rotates along the transmission rod 12, so that the No. 1 adjustment plate 13 drives the connecting rod 15 at the other end to move relative to the No. 2 adjustment plate 17, thereby driving the two No. 2 adjustment plates 17 to slide along the fixed rod 10, and then driving the support frame 21 fixed on one side of the two No. 2 adjustment plates 17 to move relative to each other. At this time, the support frame 21 drives the pull ring 4 to be adjusted synchronously through the hanging ring 22, so that the pull ring 4 drives the collection bag 3 to be tightened by stretching, thereby completing the sealing of the waste liquid inside the collection bag 3, so as to facilitate the subsequent waste treatment by the staff.
