The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figure 1 As shown, an automatic waste liquid discharge system for a buffer unit of a high-efficiency vacuum filtration device is characterized by comprising a vacuum filtration component 1 and a vacuum pump 2, wherein at least two sets of parallel drainage structures 3 are provided between the vacuum filtration component 1 and the vacuum pump 2, and the drainage structure 3 includes a buffer bottle 31, wherein the buffer bottle 31 is provided with a first bidirectional switch 32 that communicates with the outside world.

[0022] The first one-way valve 33 is connected to the buffer bottle 31 through a pipe. The other side of the first one-way valve 33 is connected to the suction filter assembly 1 through a pipe. The liquid in the suction filter assembly 1 flows into the buffer bottle 31 through the first one-way valve 33.

[0023] The second one-way valve 34 is connected to the bottom of the buffer bottle 31 through a pipe, and the liquid in the buffer bottle 31 flows out through the second one-way valve 34.

[0024] Vacuum pump 2 is connected to the upper side of buffer bottle 31 via a second two-way switch 35 and a pipe.

[0025] Multiple drainage structures 3 are arranged in parallel. After the vacuum pump 2 is started, the corresponding buffer bottle 31 can be switched to store liquid as needed. After the liquid is stored to a certain amount, the buffer bottle 31 can be closed and other buffer bottles 31 can be opened at the same time, so that the buffer bottle 31 can switch to continue storing liquid. Then, the second one-way valve 34 and the first two-way switch 32 are controlled to make the buffer bottle 31 full of liquid automatically drain under normal pressure. At this time, a larger amount of liquid can be stored, and storage and discharge can be carried out simultaneously, improving work efficiency.

[0026] At this time, the liquid drainage system needs to draw liquid from the outside through the filtration assembly 1 to the buffer bottle 31. In this embodiment, the first one-way valve 33, the first two-way switch 32, the second two-way switch 35, and the buffer bottle 31 are all connected to the upper side of the buffer bottle 31. At this time, the liquid is drawn by the vacuum pump 2, that is, by controlling the pressure in the buffer bottle 31. Therefore, in order to avoid the liquid blocking the connection between the vacuum pump 2 and the outside, affecting the liquid drawing and drainage effect, the first two-way switch 32, the second two-way switch 35, and the buffer bottle 31 are all connected to the upper side of the buffer bottle 31. At the same time, the first one-way valve 33 is also connected to the upper side of the buffer bottle 31. In this way, the first one-way valve 33 and the buffer bottle 31 are not connected to the liquid, and the negative pressure in the buffer bottle 31 can be directly connected to the filtration assembly 1 through the first one-way valve 33, so that the liquid can flow along the filtration assembly 1, the first one-way valve 33, and the buffer bottle 31 to achieve efficient liquid drawing.

[0027] The filtration assembly 1 is used to set in the position of the liquid to be drawn. At this time, the filtration assembly 1 includes a communication structure, one side of the communication structure is provided with an output interface, and the other side of the communication structure is provided with a plurality of input interfaces. The input interface and the output interface are in communication, the input interface is connected to the filtration head through the connecting pipe, and the output structure is connected to the first one-way valve 33 through the pipeline. A plurality of filtration heads are provided and then connected to the input interface of the communication structure. In this way, a plurality of different positions of the liquid can be drawn at the same time, and then connected through the communication structure, and the communication structure is connected to the first one-way valve 33 through the output interface.

[0028] Further, at this time, the input interface position is provided with a control switch for controlling the communication between the corresponding filtration head and the output interface. The control switch can be a manual switch valve. After the corresponding connecting pipe and filtration head are provided, the communication between the corresponding filtration head and the output interface can be controlled by the manual switch valve, that is, the communication between the corresponding filtration head and the buffer bottle 31 through the first one-way valve 33 is controlled. If the filtration head is placed in different positions, the liquid in different positions can be drawn.

[0029] Further, at this time, the output interface is connected to the output pipe, the output pipe is provided with a plurality of connecting heads, and the first one-way valve 33 of the liquid drainage structure 3 is connected to the connecting head through the pipeline. Since a plurality of parallel liquid drainage structures 3 are provided, in order to facilitate connection at this time, the connecting head at this time adopts a quick release connector, and the output interface and the input interface position are connected through the quick release connector. In this way, the connection between the pipelines is facilitated during use.

[0030] Meanwhile, the vacuum pump 2 is connected with an exhaust pipe, the exhaust pipe is provided with a plurality of exhaust joints, and the second two-way switch 35 of the liquid discharge structure 3 is connected with the exhaust joints through a pipeline.

[0031] Meanwhile, in order to realize automatic control, at this time, the first one-way valve 33, the second one-way valve 34, the first two-way switch 32 and the second two-way switch 35 are provided with corresponding electromagnetic valves for controlling the opening and closing of the first one-way valve 33, the second one-way valve 34, the first two-way switch 32 and the second two-way switch 35.

[0032] Further, in order to avoid that the liquid in the buffer bottle 31 is too much to overflow and affect the normal use of the buffer bottle 31, in the embodiment, the buffer bottle 31 is provided with a liquid level detection structure for detecting the liquid height, and the liquid level detection structure is a liquid level sensor. The liquid level sensor is used to detect the height of the liquid in the buffer bottle 31, when the height reaches a preset height, the corresponding first one-way valve 33 and second two-way switch 35 are closed by the electromagnetic valve to stop the liquid from entering the buffer bottle 31, and then the first two-way switch 32 and the second one-way valve 34 are controlled to be opened, so that the liquid can flow out from the position of the second one-way valve 34, thereby realizing the liquid discharge process, and at the same time, the other buffer bottles 31 can continue to draw liquid, so as to realize uninterrupted liquid drawing and automatic liquid discharge and improve the efficiency.

[0033] The technical features of the above embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the range disclosed in the specification.

[0034] The above embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
