They also have good high temperature resistance and can work stably for a long time in a high temperature environment without being easily deformed or damaged. Therefore, polytetrafluoroethylene liquid filter bags are also widely used in the food industry to ensure the quality and safety of the products.

Moreover, after the filtration is completed, a large amount of liquid will remain inside the liquid filter bag, resulting in poor filtration effect and waste of liquid. Utility Model Content

[0016] The utility model has the following beneficial effects:

[0017] 1.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a high-efficiency polytetrafluoroethylene liquid filter bag, including a filter bag body 1, the filter bag body 1 is made of polytetrafluoroethylene material and is used to achieve solid-liquid separation. The top of the filter bag body 1 is fixedly connected with an upper pressure plate 2, and the upper pressure plate 2 is located at the top of the filter bag body 1. Its main function is to cooperate with the lower pressure plate 3 to apply pressure to the impurities in the filter bag body 1. A feed port 21 is opened on the surface of the upper pressure plate 2, and a cover plate 22 is hinged on the surface of the upper pressure plate 2. The feed port 21 is used to introduce the liquid to be filtered, and can be opened or closed by the cover plate 22.

[0027] Reference Figure 1 - Figure 2The bottom surface of the filter bag body 1 is fixedly connected with a lower pressure plate 3. The function of the lower pressure plate 3 is to provide a supporting platform so that when pressure is applied, the pressure can be evenly transmitted to the impurities inside the filter bag body 1, squeezing out the residual liquid in the impurities to achieve solid-liquid separation. The two ends of the two-way threaded rod 43 are connected to the filter bag body 1, and the two-way threaded rod 43 is connected to the filter bag body 1.

[0028] Reference Figure 1 - Figure 4 The surface of the upper pressing plate 2 is provided with a limiting assembly 5, which includes a mounting groove 51, which is provided on the surface of the upper pressing plate 2 and is used to provide a moving track for the moving plate 52. The inside of the mounting groove 51 is slidably connected with the moving plate 52, and the top of the moving plate 52 is fixedly connected with a limiting plate 53, which is slidably connected to the inside of the mounting groove 51. When the cover plate 22 covers the feed port 21, the limiting plate 53 abuts against the top of the cover plate 22, which limits the cover plate 22 and prevents the cover plate 22 from opening during the pressure application process. The inner wall of the mounting groove 51 is fixedly connected with a guide rod 54, which passes through and is slidably connected to the side wall of the movable plate 52. The function of the guide rod 54 is to guide the movement direction of the movable plate 52 and ensure its stable movement in the mounting groove 51. A return spring 55 is sleeved on the outer wall of the guide rod 54. One end of the return spring 55 is fixedly connected to the side wall of the movable plate 52, and the other end of the return spring 55 is fixedly connected to the inner wall of the mounting groove 51. The function of the return spring 55 is to provide elastic support so that the limit plate 53 maintains a stable position, and by moving the movable plate 52, the return spring 55 is compressed, so that the limit plate 53 is separated from the surface of the cover plate 22, thereby releasing the limit on the cover plate 22, facilitating the opening of the cover plate 22, and facilitating the input of liquid or the removal of impurities.

[0029] Working principle: When in use, firstly, the liquid to be filtered is put into the filter bag body 1 through the feed port 21, and then, by rotating the brake wheel 44, the bidirectional threaded rod 43 is rotated, thereby driving the two sets of moving seats 41 to move in opposite directions. Due to the hinged effect of the inclined rod 42, the upper pressing plate 2 and the lower pressing plate 3 will move toward each other, exerting pressure on the impurities in the filter bag body 1. In this process, the residual liquid in the filter bag body 1 is squeezed out of the filter bag body 1, achieving better separation of liquid and impurities and reducing liquid waste.

[0030] In order to maintain the continuity of the filtering process, a limiting assembly 5 is provided on the surface of the upper pressing plate 2. When it is necessary to squeeze the impurities in the filter bag body 1, the limiting plate 53 can be separated from the surface of the cover plate 22 by sliding the movable plate 52, thereby releasing the limit on the cover plate 22. Then, the cover plate 22 can be opened, and the liquid to be filtered can be put into the filter bag body 1. When the filtering is completed, the movable plate 52 can be slid again, so that the limiting plate 53 contacts the surface of the cover plate 22, and the cover plate 22 is limited to prevent the cover plate 22 from accidentally opening during the squeezing process.

[0031] In addition, the setting of the return spring 55 can ensure that the limit plate 53 maintains a stable position, and when the cover 22 needs to be opened, the movable plate 52 can be moved so that the return spring 55 is compressed, thereby facilitating the release of the limit on the cover 22.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
