[0003] The existing reaction kettle with filter, for example, the Chinese patent document discloses a kind of reaction kettle with suction filtration [patent number: 202220290358.2;Application publication number: CN217164384U], it includes upper kettle body and lower kettle body, upper kettle body and lower kettle body are connected by flange, its characterized in that, upper kettle body upper end central part is provided with support I, support I is provided with motor I, motor I shaft is connected with stirrer, and stirrer is inserted into lower kettle body cavity inside;Upper kettle body is provided with manhole and feed inlet;Lower kettle body outside is provided with jacket, jacket lower side is provided with hot water inlet, jacket upper side is provided with hot water outlet, and jacket lower end is provided with liquid discharge pipe;Lower kettle body lower end is provided with discharge pipe, and discharge pipe passes through jacket and extends out of jacket;Jacket outside two side walls are respectively provided with support;Upper kettle body is provided with electric liquid suction device, and electric liquid suction device is arranged on upper kettle body by support II, and electric liquid suction device lower end is inserted into lower kettle body.

But the hollow jack structure of this structure can only connect one filter tube, and the filtering efficiency is low. SUMMARY

[0005] The utility model aims at the above-mentioned problems existing in prior art, and provides a filter structure of filter-drawn kettle, which solves the technical problem of how to improve the filtering efficiency of the filter structure.

[0006] The objective of this utility model can be achieved through the following technical solution: A filtration structure for a vacuum filtration vessel includes an upper cover for being fixedly connected to the vessel body of the vacuum filtration vessel, the upper cover having a liquid outlet pipe for connecting an external pump, characterized in that the filtration structure further includes a plurality of filter tubes with micropores, a plurality of non-porous tubes passing through the filter tubes, a connecting plate pressed and fixedly connected between the upper cover and the vessel body, and a liquid collection plate having a liquid collection cavity inside and located in the upper cover, the liquid outlet pipes communicating with the liquid collection cavity, the liquid collection plate having a plurality of joints communicating with the liquid collection cavity, the top of the filter tubes being fixedly connected to the connecting plate, the bottom of the non-porous tubes extending to the bottom inside the filter tubes, and the top of the non-porous tubes passing through the connecting plate and being fixedly connected to the joints.

[0007] During installation, the top cover is fixedly connected to the vessel body, and the connecting plate is fixed between the top cover and the vessel body, allowing the filter tube and the non-porous tube to extend into the vessel body. The pump operates, causing the filtrate to enter the filter tube through micropores, then through the bottom of the non-porous tube into the non-porous tube, and finally through the connector and collection chamber before being discharged from the outlet pipe, thus achieving liquid extraction. Since the non-porous tube does not have micropores, filtration can still be achieved even when the liquid level is lower than the top of the filter tube in the later stages of filtration, improving filtration efficiency. This filtration structure also features multiple filter tubes and multiple non-porous tubes, with multiple connectors and a collection chamber for transfer, further enhancing filtration efficiency. The filter tubes, non-porous tubes, connecting plate, collection tray, and outlet pipe are all integrated into the top cover; for cleaning, simply remove the top cover to remove the components, making the filtration structure easy to clean.

[0008] In the filtration structure of the aforementioned vacuum filtration vessel, both the filter tube and the non-porous tube are cylindrical, and the central axis of the filter tube coincides with the central axis of the non-porous tube. This structure ensures smooth flow of the filtrate and stabilizes the filtration structure.

[0009] In the above-described filtration structure of a vacuum filtration vessel, the collection tray is disc-shaped or cuboid-shaped, the outlet pipe is connected to the center of the top of the collection tray, and the connector is located at the bottom of the collection tray. This structure ensures a uniform flow of filtrate and stabilizes the filtration structure.

[0010] In the above-described filtration structure of a vacuum filter, the top of the filter tube has a threaded connection, and the bottom of the connection has an annular retaining flange. The connection passes through the connecting plate and extends into the upper cover, where it is locked with a nut. This structure facilitates the fastening of the filter tube to the connecting plate.

[0011] In the filtration structure of the aforementioned vacuum filter, the top of the non-porous tube passes through the connecting portion and extends into the upper cover, where it is then fixedly connected to the connector. This structure allows the non-porous tube to be directly connected to the connector, making the installation of the non-porous tube convenient.

[0012] In the filtration structure of the aforementioned vacuum filtration vessel, the non-porous tube is either a steel pipe or a flexible hose. A steel pipe is used when the filtrate temperature is high, while a plastic flexible hose can be used when the filtrate temperature is low, ensuring that the non-porous tube will not deform during filtration.

[0013] In the aforementioned filtration structure of a vacuum filtration vessel, the filtration structure further includes a fixed plate and several fixed rods. The filter tube passes through the fixed plate, the bottom of each fixed rod is fixedly connected to the fixed plate, and the top of each fixed rod is fixedly connected to the connecting plate. This structure, through the arrangement of the fixed plate and fixed rods, can improve the stability of the filter tube and the non-porous tube.

[0014] In the above-described filtration structure of a vacuum filter, both the fixing plate and the fixing rod are made of polytetrafluoroethylene (PTFE). PTFE has extremely wide temperature adaptability, is resistant to strong acids, strong alkalis, and organic solvents, and exhibits good stability.

[0015] Compared with the prior art, the filtration structure of the vacuum filter provided by this utility model has the following advantages:

[0016] 1. The filter tube of this filter structure has micropores, while the non-porous tube does not have micropores. Therefore, filtration can still be achieved when the liquid level is lower than the top of the filter tube in the later stage of filtration, thus improving filtration efficiency.

[0017] 2. The filter tube, non-porous tube, connecting plate, liquid collection tray and liquid outlet tube of this filter structure are all integrated on the top cover. When cleaning, you only need to remove the top cover to remove them, making the filter structure easy to clean. Attached Figure Description
