The receiving pool 1 has a receiving space 11 capable of receiving waste liquid, and the receiving pool 1 has an inlet connected to the receiving space 11 and a first through hole connected to the receiving space 11 is opened on its side wall. The liquid inlet pipe 2 is connected to the first through hole on the side wall of the receiving pool 1 and is used to introduce waste liquid into the receiving space 11. The output port of the air curtain machine 4 corresponds to the inlet, and the air curtain machine 4 is used to form an air curtain above the inlet to shield the receiving space 11 through air flow. The filter mechanism 5 is located on the side of the receiving pool 1 away from the air curtain machine 4 and on the path of the air curtain. The filter mechanism 5 includes a channel 51 and a filter cartridge 52. The channel 51 has a receiving port relative to the air curtain machine 4. The channel 51 is also provided with at least one filter section 511. The end of the filter section 511 away from the receiving pool 1 is higher than the end thereof close to the receiving pool 1. The filter cartridge 52 is received in the filter section 511. The filter cartridge 52 is provided with a plurality of filter plates 521 along its axial direction. The filter plates 521 are provided with a plurality of holes. One end of the liquid collecting pipe 6 is connected to the bottom of the filter section 511, and the other end is connected to the receiving space 11.

[0036] In this embodiment, the waste liquid ventilation treatment device is capable of forming an air curtain above the entrance of the receiving pool 1 by setting an air curtain machine 4, and the effect of shielding the receiving space 11 in the receiving pool 1 is achieved through the action of the air flow, thereby preventing the gas-liquid mixture from flowing out from the entrance, and the air flow is directed toward the filtering mechanism 5, and the gas-liquid mixture can be blown into the filtering mechanism 5, and the air flow can also drive the filter cartridge 52 to rotate. After rotation, the filter cartridge 52 and its own structure can block the liquid in the gas-liquid mixture, making it more difficult for the liquid to climb, thereby achieving gas-liquid separation, the gas part flows out through the channel 51, and the liquid part is collected by the liquid collecting pipe 6 and then flows back into the receiving pool 1, and the channel 51 can be directly connected to the main ventilation system, the air curtain machine 4 cooperates with the channel 51 to realize the ventilation and discharge of the receiving pool 1 while avoiding affecting the working space, thereby solving the technical problem of safety hazards caused by the evaporation and splashing of the existing waste liquid gas-liquid mixture.

[0037] In addition, in conjunction with the drawings, it should be noted that the drawings are not actual sizes but only schematic diagrams. In fact, the receiving pool 1 can occupy a large space, and the air curtain machine 4 used can also be selected according to actual needs.

[0038] In an embodiment of the waste liquid ventilation treatment device, the filter cartridge 52 is coaxially arranged with the filter section 511. In this embodiment, the filter cartridge 52 and the filter section 511 are coaxially arranged, which is conducive to the flow of the gas-liquid mixture.

[0039] Specifically, the filter segment 511 and the filter cartridge 52 inside can be combined into a whole filter, wherein the diameter of the filter segment 511 and the diameter of the filter cartridge 52 are both larger than the diameter of other channels 51, so that the filter cartridge 52 can be prevented from separating from the filter segment 511, and at this time a step is formed between the filter segment 511 and the channel 51, and the filter cartridge 52 can be rotatably connected to the step.

[0040] In an embodiment of the waste liquid ventilation treatment device, the channel 51 has a receiving section 512, the receiving section 512 is funnel-shaped, the port diameter of the receiving section 512 close to the receiving pool 1 is larger than the port diameter away from the receiving pool 1, and the port of the receiving section 512 close to the receiving pool 1 is a receiving port. In this embodiment, by being set in a funnel shape, more air flow and gas-liquid mixture from the air curtain machine 4 can be received to prevent the gas-liquid mixture from leaking from the side of the filter mechanism 5.

[0041] In an embodiment of the waste liquid ventilation treatment device, the filter mechanism 5 further includes an exhaust fan 53, which is located behind the filter mechanism 5 in the path of the channel 51. In this embodiment, the exhaust fan 53 can be provided to conveniently exhaust the gas in the channel 51.

A guide hole is opened on the guide plate 54, and a plurality of first protrusions 541 are provided on the inner wall of the guide hole. Each first protrusion 541 twists itself to form a guide arc surface 5411.

[0043] In addition, the exhaust fan 53 is also conducive to forming a negative pressure in the channel 51, thereby facilitating the gas-liquid mixture in the receiving pool 1 to enter the channel 51.

[0044] In this embodiment, specifically, the first protrusion 541 can be a rectangular block or a triangular block, and the twisting angle can take into account the twisting limit that the first protrusion 541 itself can withstand, preferably 1°-30°. By forming a guide arc surface 5411, the guide arc surface 5411 and the channel 51 guide at a certain angle, which is conducive to forming a spiral air flow and is more conducive to driving the filter cartridge 52 to rotate.

[0045] In an embodiment of the waste liquid ventilation treatment device, a plurality of second protrusions 522 are provided on the inner walls of both ends of the filter cartridge 52, and each second protrusion 522 twists itself.

[0046] In an embodiment of the waste liquid ventilation treatment device, a plurality of circles of first filter holes 523 are formed along the axial direction of the side wall of the filter cartridge 52. In this embodiment, by forming a plurality of circles of first filter holes 523, it is convenient to throw the liquid out of the first filter holes 523 during the rotation process, so as to facilitate the collection and reflux.

[0047] In an embodiment of the waste liquid ventilation treatment device, the filter mechanism 5 further includes an annular outer cylinder 55, which is sleeved on the filter cylinder 52, and a plurality of circles of second filter holes 551 are provided on the side wall of the annular outer cylinder 55 along its axial direction. In this embodiment, similar to the previous embodiment, by providing a plurality of circles of second filter holes 551, it is possible to facilitate the liquid to be thrown out of the second filter holes 551 during the rotation process, so as to facilitate the collection and reflux.

[0048] It can be understood that, since the filtering section 511 is arranged obliquely, the liquid will flow back under its own gravity when it falls back.

[0049] In an embodiment of the waste liquid ventilation treatment device, a second through hole is further provided on a side of the receiving pool 1 away from the liquid inlet pipe 2, and the waste liquid ventilation treatment device further comprises a liquid outlet pipe 3, which is connected to the second through hole. In this embodiment, by providing the second through hole and the liquid outlet pipe 3, the waste liquid can be conveniently discharged from the receiving pool 1.

In this embodiment, by providing the box 7, it is possible to prevent debris from entering the channel 51 and to stabilize the overall filter mechanism 5.

[0051] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
