[0002] Filters are a common type of industrial equipment used in food and beverage, fine chemical, petrochemical, pharmaceutical and bioengineering, automobile manufacturing, water treatment and other fields. Liquid materials often need to be filtered to remove insoluble substances such as flocculent matter, colloidal matter, and mechanical impurities.

[0003] Existing filters consist of a filter tank and a cover. The cover is placed on the tank and secured by a locking mechanism. In current technology, the cover is typically hinged to the tank or the two can be separated. However, for bulky multi-bag filters, the filter cartridges inside the filter need to be replaced frequently. Each time the filter cartridge is replaced, the locking mechanism must be loosened and an external force must be applied to the cover away from the tank to open the cover. This usually requires the assistance of large hoisting equipment, which can easily limit the space available. Furthermore, the opening and closing operation is cumbersome, time-consuming, and labor-intensive, which also seriously affects work efficiency. Utility Model Content

[0033] like Figures 1 to 4 As shown, this application provides a filtration device, which includes a tank 1, a cover 2, and an elastic member 3. The tank 1 has an opening at the top, and a partition filter plate 4 is provided inside the tank 1 to divide the tank 1 along its height direction. The partition filter plate 4 is provided with filter holes 41, and filter elements 5 are provided in the filter holes 41. The cover 2 is hinged to the tank 1, so that the opening on the tank 1 can be opened or closed. One end of the elastic member 3 is connected to the tank 1, and the other end is connected to the cover 2. When the cover 2 closes the opening, the elastic member 3 is in a stretched state. When the cover 2 opens the opening, the elastic member 3 is in a natural state. When the cover 2 loses the closing restriction function of the locking member that locks the cover 2, the elastic member 3 can switch from the stretched state to the natural state to open the cover 2.

[0034] By connecting the elastic element 3 between the cover 2 and the tank 1, when the cover 2 is closed, the cover 2 will stretch the elastic element 3, putting it in a stretched state and accumulating potential energy; when the cover 2 needs to be opened, it is only necessary to loosen the locking element that locks the cover 2, so that the elastic element 3 pulls the cover 2, causing the cover 2 to open automatically. Therefore, it is not necessary to use large hoisting equipment or only requires a small amount of manpower, saving manpower, material resources and operating space. It is also not necessary to remove the cover 2 as a whole, which also improves the efficiency of opening the cover 2.

[0035] For example, the elastic element 3 may be, but is not limited to, a spring. It should be noted that the size of the spring can be selected based on factors such as the size and weight of the cover 2 and the opening angle of the cover 2.

[0036] Furthermore, the locking mechanism of the cover 2 is also a prior art structure, which can be a bolt passing through the cover 2 and the tank 1 and locked by a nut; or it can be a buckle or other components. The cover 2 and the tank 1 are hinged together by a hinge shaft, and the connection method of the hinge shaft is prior art, so it will not be described in detail.

[0037] like Figure 2 As shown, to facilitate the fixing of the elastic element 3, in some embodiments, a first mounting seat 6 is provided on the tank body 1, and a second mounting seat 7 is provided on the cover body 2. The first mounting seat 6 and the second mounting seat 7 are located on the same side of the hinge axis of the tank body 1 and the cover body 2, and the first mounting seat 6 and the second mounting seat 7 are located on the upper and lower sides of the hinge point of the cover body 2 and the tank body 1. The elastic element 3 connects the first mounting seat 6 and the second mounting seat 7 so that the cover body 2 can stretch the elastic element 3 when the opening is closed. Exemplarily, the elastic element 3 and the first mounting seat 6, as well as the elastic element 3 and the second mounting seat 7, can be connected by welding, but are not limited to this method.

[0038] like Figure 2 As shown, in some embodiments, a protective sleeve 8 is fitted over the outer side of the elastic element 3. The protective sleeve 8 can reduce the contact of the elastic element 3 with external corrosive substances and extend the service life of the elastic element 3. Further, in the current embodiment, the protective sleeve 8 is flexible, and its two ends are connected to the first mounting base 6 and the second mounting base 7. Thus, during the relative movement of the first mounting base 6 and the second mounting base 7, the protective sleeve 8 can stretch synchronously with the elastic element 3, thereby providing auxiliary restoring force to the elastic element 3 and minimizing the usable size of the elastic element 3. Exemplarily, the protective sleeve 8 can be, but is not limited to, made of high-strength and flexible Kevlar fiber.

[0039] Furthermore, such as Figure 2 As shown, to ensure the stable connection of the protective sleeve 8, fixing rings 9 are fixed at both ends of the protective sleeve 8. Each fixing ring 9 has a first through hole. The first mounting base 6 and the second mounting base 7 have mounting grooves. The bottom of each mounting groove has a second through hole that mates with the first through hole. The fixing ring 9 is placed within the mounting groove and is fixed to the first mounting base 6 and the second mounting base 7 by a connector passing through the first and second through holes. In some embodiments, one of the first and second through holes can be a screw hole, and the connector can be a bolt. In other alternative embodiments, the first and second through holes can be through holes, and the connector can be a combination of bolts and nuts.

[0040] In some alternative embodiments, the protective sleeve 8 can also be bonded to the first mounting base 6 and the second mounting base 7 with strong adhesive. The type of strong adhesive is not specifically limited, as long as it ensures that the protective sleeve 8 does not fall off.

[0041] like Figure 1As shown, in some embodiments, the lid 2 is also provided with a second handle 105, which assists in opening the lid and provides convenience. In addition, the lid 2 is also provided with a pressure relief valve 109, which allows for venting and pressure relief. To ensure a tight seal when the lid 2 is closed, a sealing strip is provided on the edge of the lid 2 or the edge of the can 1, so that when the lid 2 is closed on the can 1, the two can press against the sealing strip to achieve a seal.

[0042] like Figure 1 As shown, in some embodiments, the tank 1 includes an upper tank 11 and a lower tank 12, which are detachably connected by bolts. An opening is located at the top of the upper tank 11, and a separator filter plate 4 is enclosed at the bottom of the upper tank 11. An inlet 10 is provided on the upper tank 11, through which liquid material is injected. The material is then filtered through the filter element 5 on the separator filter plate 4, and the filtered liquid enters the lower tank 12. To facilitate the collection of the filtered filtrate, the lower tank 12 is provided with an outlet 102. Exemplarily, the inlet 10 and outlet 102 are quick-connect interfaces for easy connection to a material pipe. In the current embodiment, a sealing ring is also provided on the edge of either the upper tank 11 or the lower tank 12, thereby pressing the sealing ring together when the upper tank 11 and the lower tank 12 are connected to achieve a seal. The detachable design of the upper tank 11 and the lower tank 12 allows the upper tank 11 to be removed after long-term use, making it convenient to clean the impurities remaining in the lower tank 12, thereby thoroughly cleaning the lower tank 12.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, to better fix the filter element 5, the filter holes 41 are stepped, and the lower end of the filter element 5 is also stepped, thus fitting into the filter holes 41. Furthermore, a fixing plate 110 is also provided inside the upper tank 11. The upper ends of one or more filter elements 5 are fixed to the fixing plate 110. A screw 106 extending along the height direction of the tank 1 is provided on the separator filter plate 4. The screw 106 and the separator filter plate 4 can be, but are not limited to, screwed together. The fixing plate 110 is provided with a socket hole, through which the fixing plate 110 is sleeved onto the screw 106. A nut is screwed onto the screw 106, thereby locking the filter element 5 together with the fixing plate 110 through the nut. For example, the separator filter plate 4 is provided with 21 filter holes 41, and 7 screws 106 and 7 fixing plates 110 are provided, with 3 filter elements 5 correspondingly arranged on each fixing plate 110.

[0044] like Figure 1As shown, after the liquid material in the upper tank 11 is filtered, residual waste liquid will remain in the upper tank 11. To facilitate the discharge of the waste liquid, in some embodiments, the upper tank 11 is also provided with a first drain port 101, which is located below the feed port 10, so that the waste liquid can be discharged through the first drain port 101; when cleaning the upper tank 11 and the filter element 5, the waste liquid in the upper tank 11 and the filter element 5 can also be discharged. Similarly, in order to drain the filtrate in the lower tank 12, the lower tank 12 is also provided with a second drain port 103, with the discharge port 102 located above the second drain port 103, and the second drain port 103 located at the lowest point of the lower tank 12, so that the filtrate in the lower tank 12 and the waste liquid used to clean the lower tank 12 can be drained through the second drain port 103.

[0045] like Figure 1 As shown, in some embodiments, to make the tank 1 more stable, the lower tank 12 is also provided with multiple support feet 108. In addition, when it is necessary to disassemble the upper tank 11, a first handle 104 is provided on the side of the upper tank 11 to facilitate rotation or pushing and pulling of the upper tank 11, so as to facilitate the application of force.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
