Description

Technical Field

[0001] This utility model relates to the field of filtration technology, specifically a precision filtration device. Background Technology

[0002] Vacuum filtration is an experimental or industrial technique that uses the negative pressure generated by a vacuum pump to accelerate the passage of liquid through a filter medium (such as filter paper or filter cloth) to achieve solid-liquid separation. During vacuum filtration, solid substances are trapped on the filter medium to form a filter cake, while the liquid rapidly passes through the medium into a receiving container. Compared to gravity filtration, it significantly shortens filtration time and improves filtration efficiency. It is commonly used in chemical experiments for the separation of precipitates and in industrial production for the rapid separation of liquids and solid particles. With the development of modern life, vacuum filtration devices have become indispensable equipment in laboratories.

[0003] An investigation revealed that a Chinese utility model patent (CN203899302U) discloses a filtration device, comprising a storage tank, a filtrate tank, and a filtration bucket. The storage tank's outlet is positioned opposite the filtration bucket. A filter bag is fitted onto the filtration bucket, and a filtrate drain pipe is located at the bottom of the filtration bucket, connecting to the inlet at the top of the filtrate tank. The filtrate tank has an outlet at its bottom. The storage tank contains a vertically mounted storage tank plate with a gap between its top and the top of the storage tank. The storage tank plate is located between the outlet and the inlet at the top of the storage tank, and a slag discharge port is located at its lower end. Similarly, the filtrate tank contains a vertically mounted filtrate tank plate with a gap between its top and the top of the filtrate tank. The filtrate tank plate is located between the inlet and the outlet at the bottom of the filtrate tank, and a slag discharge port is located at its lower end. It has a novel structure, simple and flexible operation, high filtration efficiency, and strong adaptability.

[0004] The aforementioned patent is not very convenient for users. When the filter paper reaches its limit, it cannot provide a quick filter paper replacement, which increases the time required to replace the filter paper, increases the complexity of the work for the staff, affects the speed of subsequent work, reduces the overall work efficiency, and is not conducive to the long-term use of the filtration device.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides a technical solution: a precision filtration and defiltration device, including a workbench 1, a purification frame 2 movably connected to the top of the workbench 1, a frame plug 3 movably connected to the top of the purification frame 2, a connecting port 4 fixedly connected to the top of the frame plug 3, a locking frame 5 fixedly connected to one side of the connecting port 4, a locking arc block 6 movably connected to one side of the locking frame 5, and an inner spring 7 fixedly connected to one side of the locking arc block 6.

[0027] A hollow block 8 is fixedly connected to one end of the inner spring 7, and a connector 9 is fixedly connected to one side of the hollow block 8. A leak-proof rubber pad 10 is fixedly connected to the bottom of the connector 9, a hinge 20 is fixedly connected to one side of the connector 9, and a liquid injection frame 11 is fixedly connected to the top of the connector 9. This makes the precision filtration and vacuuming device more convenient to use. When the filter paper reaches its limit, it can provide a quick filter paper replacement effect, thereby reducing the time required to replace the filter paper, reducing the complexity of the work of the staff, improving the speed of subsequent work, improving the overall work efficiency, and facilitating the long-term use of the vacuuming device.

[0028] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: a threaded outer tube 12 is fixedly connected to the outer wall of the purification frame 2, and a threaded lock 13 is movably connected to the outer wall of the threaded outer tube 12 to facilitate locking with an external air extraction component. An air extraction threaded tube 14 is movably connected inside the threaded lock 13, and an air extraction pump 15 is fixedly connected to one end of the air extraction threaded tube 14 to facilitate rapid extraction of gas from the interior of other components, thereby generating negative pressure inside them.

[0029] The bottom of the workbench 1 is fixedly connected to an electric push rod 16, and there are four electric push rods 16, which can adjust the overall working height of the device. The bottom end of the electric push rod 16 is fixedly connected to a base 17, and the bottom area of ​​the base 17 is larger than the bottom area of ​​the electric push rod 16, which improves the overall working stability of the device.

[0030] The bottom of the workbench 1 is movably connected to a bottom bolt 18, and the outer wall of the bottom bolt 18 is movably connected to a handling handle 19, which facilitates the overall handling of the device.

[0031] like Figure 1-5As shown, when a user needs to use a precision filtration device, if the filter paper needs to be replaced, press the locking arc block 6 to compress the inner spring 7, causing the locking arc block 6 to retract into the hollow block 8. At this time, rotate the anti-leakage pad 10, the interface 9, and the liquid injection frame 11 along the hinge 20, place the filter paper to be replaced on the top of the interface 4, and then rotate the liquid injection frame 11 to make the locking arc block 6 engage with the locking frame 5. When the water to be filtered is injected into the liquid injection frame 11, the air pump 15 also starts to work. The air pump 15 works so that the air extraction threaded pipe 14 and the threaded outer pipe 12 can extract the air from the purification frame 2, thereby creating a negative pressure in the purification frame 2. This causes the liquid in the liquid injection frame 11 to be filtered by the filter paper and fall into the purification frame 2.
