The present invention will be described in further detail with reference to the accompanying drawings:

as shown in fig. 1, a waste liquid cabinet for a laboratory comprises a cabinet body 1, a waste liquid dumping platform 2, a cabinet body cover plate 3, a cabinet door 4 and a bearing frame 8; the cabinet body cover plate 3 is arranged at the top of the cabinet body 1 and is movably connected with the cabinet body 1; the cabinet door 4 is arranged at the side part of the cabinet body 1 and is movably connected with the cabinet body 1; when the waste liquid barrel 9 is placed, the waste liquid barrel 9 is arranged on the bearing frame 8; the waste liquid dumping platform 2 is arranged inside the cabinet body 1, a ventilating pipeline 5, a dumping pipeline 7 and an exhaust pipeline 11 are arranged on the waste liquid dumping platform 2, and a first sealing cover is arranged on the exhaust pipeline 11; the bottom end of the dumping pipeline 7 and the bottom end of the exhaust pipeline 11 extend into the waste liquid barrel 9 and are arranged in parallel; the bottom end of the ventilation pipeline 5 is flush with the upper end surface of the waste liquid barrel 9; the arrangement of the ventilation pipeline 5, the dumping pipeline 7 and the exhaust pipeline 11 and the corresponding positions thereof effectively enables the waste liquid cabinet to have an anti-overflow function. When dumping the waste liquid, the gas in the barrel can be discharged from the ventilation pipeline 5, so that the waste liquid dumping process is safer and smoother. And an adsorption device is arranged at the vent hole, so that the harm of waste gas can be effectively reduced. In order to facilitate the movement of the waste container 9, the bottom of the carrier 8 is provided with pulleys.

As shown in fig. 1 and 2, the height of the bearing frame 8 is greater than that of the waste liquid barrel 9, so that an idle waste liquid barrel can be placed at the bottom of the bearing frame 8, and the utilization rate of the waste liquid cabinet is effectively improved.

As shown in fig. 3 and 4, a piston 96 is movably arranged on the waste liquid dumping platform 2, and the piston 96 is matched with the waste liquid barrel 9; the piston 96 is provided with a first port 91, a second port 92 and a third port 93, the first port 91 is connected with the ventilation duct 5, the second port 92 is connected with the dumping duct 7, and the third port 93 is connected with the exhaust duct 11.

As shown in fig. 1, a seal 94 is further provided at each of a connection point between the first port 91 and the ventilation duct 5, a connection point between the second port 92 and the dump duct 7, and a connection point between the third port 93 and the exhaust duct 11. The ventilation duct 5 is disposed adjacent to the tilt duct 7, and the air outlet of the ventilation duct 5 is provided with an adsorption device 51. Adsorption equipment 51 is including the adsorbent, can effectively realize spilling over the absorption of waste gas in the waste liquid, places the injury to operating personnel. As shown in fig. 5, the pouring spout of the pouring duct 7 is provided with a filter net and a second sealing lid 71. The setting of filter screen avoids debris to go into the waste liquid bucket by mistake, and the setting of the sealed lid 71 of second can prevent that waste gas volatilizees when the waste liquid cabinet is not in use. Still be provided with storing box 6 on the platform 2 is emptyd to the waste liquid, be convenient for when the waste liquid is emptyd to waste liquid bucket and waste liquid cabinet etc. widget's placing, avoided widget's loss. The inside of the cabinet body 1 still is provided with the slide rail, and the slide rail sets up in the bottom of the cabinet body 1, the slide rail sets up with the pulley cooperation that bears the frame 8 bottom, and the setting of slide rail makes bearing placing of frame 8 more stable, and it is more convenient to remove. The ventilation duct 5 is provided with a third sealing cover. When having avoided non-pouring liquid time, the waste gas that produces among the waste liquid spills over the waste liquid bucket. Still be provided with lock 10 on cabinet door 4 for the use of waste liquid cabinet is safer, is convenient for manage the waste liquid cabinet simultaneously.

When empting the waste liquid, the waste liquid gets into from empting pipeline 7, and gaseous passing through air pipe 5 absorption back discharge in the waste liquid bucket can reduce when empting the waste liquid, and waste gas is followed the bucket and is discharged the harm that causes the user. When the waste liquid is collected to be full and need to be changed waste liquid bucket 9 the accessible bears 8 and pulls out waste liquid bucket 9, very big reduction the risk in the 9 handling of waste liquid bucket.

In addition, the anti-overflow principle of the device is as follows: when the waste liquid is poured, the cabinet door 4 and the cabinet body cover plate 3 are opened. The ventilation pipeline 5 is level with the lower end of the dumping pipeline 7 and communicated with the outside atmosphere, and the first sealing cover is closed. When the liquid level in the barrel reaches a certain height, the liquid level contacts with the bottom ends of the ventilation pipeline 5 and the dumping pipeline 7 to continuously dump liquid, the liquid level submerges the lower ends of the ventilation pipeline 5 and the dumping pipeline 7 to continuously rise as shown in fig. 6A, when the liquid in the ventilation pipeline 5 and the dumping pipeline 7 rises to the pipeline opening of the dumping pipeline 7, a full liquid signal in the barrel can be visually transmitted, and dumping is stopped. The first sealing cover is now opened, i.e. the exhaust duct 11 is made the same as the atmosphere, according to the communicating vessel principle. The pressure generated by the liquid in the ventilation duct 5 and the pouring duct 7 is discharged from the exhaust duct 11, the liquid level in the ventilation duct 5 and the pouring duct 7 drops, and the liquid level in the entire barrel slightly rises as shown in fig. 6B. The device has simple structure principle, low cost and simple and convenient operation, and can realize effective anti-overflow.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
