Detailed Implementation

[0017] 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, any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art to all other embodiments obtained without creative effort should be included within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, this embodiment discloses a temperature-controlled vacuum filtration device, including a receiving mechanism, a filtering mechanism, and a liquid storage mechanism. The receiving mechanism is connected to the liquid storage mechanism through the filtering mechanism. The filtration mechanism includes a filter housing 3, a filter element 9, and a bottom connector 5. The filter housing 3 is funnel-shaped, and its top end is bolted to the receiving mechanism via a flange structure. A sandwich cavity 301 is provided inside the outer peripheral side wall of the filter housing 3. The top end of the sandwich cavity 301 is connected to a medium inlet 302 located on one side of the top end of the filter housing 3, and the bottom end of the sandwich cavity 301 is connected to a medium outlet 303 located on one side of the bottom end of the filter housing 3. A filter element 9 is provided inside the top end of the filter housing 3. A control valve 4 for controlling the inflow state is provided at the bottom end of the filter housing 3. The upper and lower ends of the control valve 4 are bolted to the bottom end of the filter housing 3 and the top end of the bottom connector 5 via flange structures, respectively. The bottom connector 5 is cylindrical, and its bottom end is inserted into the liquid storage mechanism. The outer periphery of the middle part of the bottom connector 5 is bolted to the liquid storage mechanism via a flange structure.

[0019] The filter housing 3 has a positioning protrusion ring 304 on its top inner wall, and the positioning protrusion ring 304 is coaxially arranged with the filter housing 3; the filter element 9 is arranged in a conical plate shape, and the bottom end of the filter element 9 is placed on the positioning protrusion ring 304, and the outer diameter of the bottom end of the filter element 9 is adapted to the inner diameter of the top end of the filter housing 3.

[0020] The inner edge of the top end of the positioning protrusion ring 304 is flush with the inner edge of the bottom end of the filter element 9, and the inner wall of the positioning protrusion ring 304 has an inwardly concave rounded corner structure.

[0021] During filtration, the liquid material in the receiving mechanism passes through the filter element for filtration. The filtered liquid slides along the conical surface at the bottom of the filter element, eventually flowing from the inner edge of the bottom edge of the filter element, through the inner wall of the positioning ring, to the inner wall of the filter housing. Because the inner wall of the filter housing has a sandwiched cavity containing a high-temperature or low-temperature medium, the filtered liquid in contact with the inner wall of the filter housing is heated or cooled by the medium. The temperature-controlled liquid is then sent to the liquid storage mechanism through the bottom connector. In this design, the shape and structure of the filter element increase the filtration area of ​​the liquid material, improving filtration efficiency. Simultaneously, the conical shape of the filter element allows the filtered liquid to flow down the inner wall of the filter housing. The funnel structure design of the filter housing can extend the flow path and flow time of the filtered liquid, thereby improving the temperature control effect of the filtered liquid.

[0022] The containing mechanism includes a containing shell 2 and a top cover 1. The containing shell 2 is a cylindrical shell with openings at both the top and bottom. A first glass window 201 is provided on the side wall of the containing shell 2 to facilitate observation of the internal condition of the containing shell. The bottom of the containing shell 2 is bolted to the top of the filter shell 3 through a flange structure. The top of the containing shell 2 is bolted to the top cover 1 through a flange structure. The top cover 1 is provided with a liquid inlet 101 for entering liquid raw materials, a pressure gauge 102 for pressure measurement, and an air inlet 103 for introducing gas during positive pressure filtration.

[0023] The liquid storage mechanism includes a liquid storage shell 7 and a mounting component 6. The liquid storage shell 7 is a shell-shaped structure with an open top. The bottom of the liquid storage shell 7 is connected to a roller 8 for easy movement. A second glass window 703 is provided on the side wall of the liquid storage shell 7 to facilitate observation of the internal condition of the liquid storage shell. The mounting component 6 is located at the top of the liquid storage shell 7 and is connected to the bottom connecting component 5. The mounting component 6 is shaped like a flared mouth with a small inner diameter at the top and a large inner diameter at the bottom. The top of the mounting component 6 is fitted onto the outside of the bottom connecting component 5, and the top of the mounting component 6 is bolted to the middle outer wall of the bottom connecting component 5 through a flange structure. The bottom of the mounting component 6 is bolted to the top of the liquid outlet shell 7 through a flange structure. An air extraction port 601 for evacuation is provided on the side wall of the mounting component 6, and the air extraction port 601 is connected to the inside of the mounting component 6.

[0024] In this design, during negative pressure filtration, the suction device is connected to the suction port, allowing the liquid material in the housing to pass through the filter element under negative pressure. Finally, it falls into the liquid storage housing after passing through the bottom connector. The bottom end of the bottom connector is inserted into the inside of the mounting component, allowing the filtered liquid to flow directly into the liquid storage housing. Since the filtered liquid is still highly corrosive, being sucked into the suction device would seriously affect the service life of the suction device. Therefore, the design of the mounting component and the bottom connector prevents the filtered liquid from flowing onto the side wall of the mounting component, thus avoiding affecting the suction operation of the suction port.

[0025] The liquid storage shell 7 has a liquid extraction groove 704 at its inner bottom end, and a liquid outlet 701 is provided on the side wall of the liquid storage shell 7. A liquid extraction pipe 702 is provided in the liquid outlet 701. The bottom end of the liquid extraction pipe 702 extends into the liquid extraction groove 704, and the top end of the liquid extraction pipe 702 extends out from the liquid outlet 701 and is connected to the power pump.

[0026] The design of the liquid extraction groove allows the liquid extraction tube to completely extract all the liquid inside the liquid storage shell, avoiding the situation where some liquid remains inside the liquid storage shell and cannot be completely extracted, thus further improving the effectiveness of this utility model.

[0027] This invention employs a design with a sandwiched cavity on the side wall of the filter housing. During filtration, the liquid raw material passes through the filter element in the receiving housing and then enters the liquid storage housing, thus achieving the filtration of the liquid raw material. Simultaneously, a high-temperature or low-temperature medium can be introduced through the medium inlet. After entering the sandwiched cavity, the medium flows out from the medium outlet at the bottom. By circulating the medium and utilizing the principle of heat transfer, the temperature of the filter housing and the liquid being filtered within it is raised or lowered, meeting the temperature requirements during the liquid raw material filtration process. This enables temperature-controlled filtration of liquid raw materials, further improving the effectiveness of the filtration device and bringing convenience to chemical and pharmaceutical operations.
