Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum filtration equipment, specifically relating to a parallel self-draining vacuum filtration device that can realize the vacuum filtration of multiple samples. Background Technology

[0002] A vacuum filtration apparatus is an experimental technique that uses a vacuum pump (or other pumping device) to create negative pressure (i.e., vacuum) on one side of the filtration system, thereby accelerating the passage of liquid through filter paper and achieving rapid solid-liquid separation. A standard vacuum filtration apparatus typically consists of the following components: a Buchner funnel (with a porous flat bottom to hold the filter paper); a filtration flask (to collect the filtered liquid); and a side branch for connecting to the vacuum pump; the vacuum pump generates the negative pressure (vacuum) and is the power source for the entire apparatus.

[0003] However, existing vacuum filtration devices are used alone to obtain a single sample, but when the sample demand is large, using a single vacuum filtration device will lead to low efficiency; moreover, when the vacuum filtration flask is full, it is necessary to manually disassemble the vacuum filtration flask, pour out the filtrate in the vacuum filtration flask, and then reassemble the vacuum filtration flask, which is cumbersome. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a parallel self-draining filtration device that can realize multi-sample filtration, which effectively solves the problems of low filtration efficiency and the need for manual dumping of waste liquid in existing filtration devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a parallel self-draining filtration device capable of filtration of multiple samples, comprising a filtration main pipe and a drain main pipe, wherein the filtration main pipe is provided with a connecting pipe connected to a vacuum pump; a plurality of filtration bottles are detachably connected to the filtration main pipe, and each filtration bottle is provided with a Buchner funnel; each of the plurality of filtration bottles is provided with a waste liquid port communicating with the drain main pipe, and a large waste liquid container is connected to the drain main pipe.

[0006] Furthermore, the main filtration tube is connected to several filtration branch tubes, the filtration bottle is provided with filtration ports that cooperate with the filtration branch tubes, and the filtration branch tubes are provided with filtration hoses that communicate with the filtration ports.

[0007] Furthermore, each of the aforementioned filter pipes is equipped with a filter valve.

[0008] Furthermore, the main drain pipe is connected to several branch drain pipes, and each of the branch drain pipes is equipped with a drain hose corresponding to the corresponding waste liquid outlet.

[0009] Furthermore, each of the aforementioned drain pipes is equipped with a drain valve and a check valve.

[0010] Furthermore, the main drain pipe is connected to an outlet pipe corresponding to the large waste liquid container, and a waste liquid pump is installed on the outlet pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, this invention allows for the connection of multiple filtration flasks to the main filtration pipe, enabling the vacuum pump to perform filtration on several flasks simultaneously. This allows for the simultaneous filtration of multiple samples, improving filtration efficiency. Furthermore, the inclusion of a waste outlet, drain pipe, and large waste container on the filtration flask allows the filtrate to flow into the large waste container through the waste outlet and drain pipe when the flask is full. This eliminates the need for manual emptying of the filtrate from the filtration flask repeatedly, enhancing convenience. Attached Figure Description

Detailed Implementation

[0013] A parallel self-draining filtration device capable of filtration of multiple samples, such as... Figure 1 As shown, it includes a vacuum filtration main pipe 2 and a drain pipe 8. The vacuum filtration main pipe 2 is provided with a connecting pipe 1 that is connected to a vacuum pump. Several vacuum filtration bottles 3 are detachably connected to the vacuum filtration main pipe 2. Each vacuum filtration bottle 3 is provided with a Buchner funnel 4. Each of the several vacuum filtration bottles 3 is provided with a waste liquid port that is connected to the drain pipe 8. A large waste liquid container 11 is connected to the drain pipe 8.

[0014] In use, this invention connects the connecting pipe 1 to a vacuum pump, connects several filtration flasks 3 to the main filtration pipe 2, and places the mixture to be filtered into the Buchner funnel 4. The waste liquid outlet on the filtration flask 3 is connected to the drain pipe 8, which in turn connects to the large waste liquid container 11. The vacuum pump is then started, creating a negative pressure within the filtration flask 3 through the connecting pipe 1 and the main filtration pipe 2. The filtrate in the mixture flows through the filter paper in the Buchner funnel 4 into the filtration flask 3. When the filtration flask 3 is full, the filtrate flows into the large waste liquid container 11 through the waste liquid outlet and the drain pipe 8. This design eliminates the need for manual emptying of the filtrate in the filtration flask 3 repeatedly, improving the convenience of this invention.

[0015] Furthermore, the main filtration pipe 2 is connected to a plurality of filtration branch pipes 5, and each of the plurality of filtration branch pipes 5 is provided with a filtration valve; the filtration bottle 3 is provided with a filtration port that cooperates with the filtration branch pipes 5, and the filtration branch pipes 5 are provided with a filtration hose 6 that communicates with the filtration port.

[0016] The filtration bottle 3 and the main filtration pipe 2 are connected by a filtration hose 6, which connects the filtration port on the filtration bottle 3 to the filtration branch pipe 5 on the main filtration pipe 2. In addition, the filtration valve allows the filtration branch pipe 5 to be opened or closed as needed.

[0017] Furthermore, the main drain pipe 8 is connected to several drain branch pipes, and each of the drain branch pipes is equipped with a drain valve 12 and a one-way valve 13; each of the drain branch pipes is equipped with a drain hose 7 corresponding to the corresponding waste liquid port.

[0018] The waste liquid outlet on the filtration bottle 3 is connected to the drain pipe on the drain main 8 via a drain hose 7. The drain valve 12 can be used to open and close the drain pipe to ensure the normal operation of the filtration bottle 3. In addition, the one-way valve 13 ensures that the filtrate can only flow through the filtration bottle 3 to the drain main 8, preventing cross-flow of filtrate in the filtration bottles 3 and improving the stability of this application.

[0019] Furthermore, the main drain pipe 8 is connected to an outlet pipe 9 corresponding to the waste liquid container 11, and the outlet pipe 9 is equipped with a waste liquid pump 10. By setting the waste liquid pump 10, the draining speed of the filtration bottle 3 is increased, thereby improving the draining efficiency of this application.

[0020] The working process of this utility model is as follows: In use, the connecting pipe 1 is connected to the vacuum pump, the filtration port on the filtration bottle 3 is connected to the filtration branch pipe 5 on the filtration main pipe 2 through the filtration hose 6, the waste liquid port on the filtration bottle 3 is connected to the drain branch pipe on the drain main pipe 8 through the drain hose 7, and the liquid outlet pipe 9 is connected to the waste liquid container 11.

[0021] Filtration process: Start the vacuum pump, open the filtration valve, and close the drain valve 12; The vacuum pump creates a negative pressure in the filtration flask 3 through the connecting pipe 1, the main filtration pipe 2, the filtration branch pipe 5, and the filtration hose 6. The filtrate in the mixture flows into the filtration flask 3 through the filter paper in the Buchner funnel 4.

[0022] Drainage process: When the filtrate in the filtration bottle 3 is full, start the waste liquid pump 10, close the filtration valve, and open the drain valve 12; the filtrate flows into the large waste liquid container 11 through the waste liquid port, drain hose 7, drain branch pipe, drain main pipe 8, and outlet pipe 9; this eliminates the need for manual emptying of the filtrate in the filtration bottle 3 during use, improving the convenience of this application.
