Description

Technical Field

[0001] This utility model relates to the field of filter element maintenance cover disassembly and installation equipment, specifically, to a convenient disassembly and installation device for filter element cleaning cover. Background Technology

[0002] The traditional method for removing the top cover of a small vertical filter involves first setting up a temporary bolt removal platform around the filter using scaffolding. Then, using a wrench, several hexagonal bolts are loosened one by one. A chain hoist lifting device is then placed on the scaffolding platform, directly opposite the center of the top cover, and the filter top cover is slowly lifted.

[0003] The above solution requires setting up scaffolding around the vertical filter before installing and operating the chain hoist to raise and lower the top cover, which makes the operation less convenient. In addition, the traditional hex bolt connection is difficult to install due to insufficient space for wrench operation, and is not suitable for use scenarios where the top cover is frequently disassembled to clean the filter element. In summary, the process of disassembling and installing the top cover before and after cleaning the filter element needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a convenient top cover removal and installation device for cleaning filter cartridges.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A convenient top cover removal and installation device for cleaning filter cartridges includes a small vertical filter body. The small vertical filter body includes a top cover, a strip flat steel bar, a mounting base, a first long screw, an ear-shaped nut, a mounting plate, a rotating tube, an internally threaded tube, and a lifting assembly.

[0007] Several groups of flat bar strips are welded circumferentially to the top area and top cover of the small vertical filter body, and correspond one to one. Each group includes two parallel and spaced flat bar strips.

[0008] The mounting base is rotatably positioned between each set of flat steel bars welded to the top area of ​​the small vertical filter body;

[0009] The first long screw is welded to the mounting base, and the end of the first long screw away from the mounting base is threaded with an ear-shaped nut that contacts the strip flat steel on the top cover;

[0010] The mounting plate is welded onto the small vertical filter body;

[0011] One end of the L-shaped rotating tube is rotatably connected to the mounting plate;

[0012] The internally threaded tube is welded to the other end of the rotating tube, and the internal thread of the internally threaded tube is fitted with a lifting component that is welded to the top cover.

[0013] Furthermore, the lifting assembly includes a second long screw, a mounting block, a support plate, and a handwheel.

[0014] The second longest screw is connected to the internal threaded pipe thread;

[0015] The mounting blocks are welded to one end of the second long screw and the surface of the top cover, respectively.

[0016] Several support plates are circumferentially welded to the other end of the second long screw;

[0017] The handwheel is welded to the support plate.

[0018] Furthermore, a sleeve is welded to the body of the small vertical filter, which is located directly below the mounting plate. One end of the rotating tube is inside the sleeve and fits against the inner wall of the sleeve.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0029] like Figure 1 and Figure 2 As shown, a convenient disassembly and installation device for a filter element cleaning top cover 101 includes a small vertical filter body 1. The small vertical filter body 1 includes a top cover 101, a strip flat steel bar 2, a mounting base 3, a first long screw 4, an ear-shaped nut 5, a mounting plate 6, a rotating tube 7, an internally threaded tube 8, and a lifting assembly.

[0030] Several groups of strip flat steel 2 are respectively welded to the top area of ​​the small vertical filter body 1 and the top cover 101 in a circular manner and correspond one to one. Each group includes two parallel and spaced strip flat steel 2.

[0031] Mounting base 3 is rotatably set between each group of strip flat steel 2 welded to the top area of ​​the small vertical filter body 1 (specifically, each group of strip flat steel 2 welded to the top area of ​​the small vertical filter body 1 is rotatably connected to a rotating shaft, and mounting base 3 is welded on the rotating shaft. Furthermore, the relative position between the rotating shaft and the strip flat steel 2 is constrained by pins, thereby reducing assembly errors).

[0032] The first long screw 4 is welded to the mounting base 3, and the end of the first long screw 4 away from the mounting base 3 is threaded with an ear-shaped nut 5 that contacts the strip flat steel 2 on the top cover 101;

[0033] Mounting plate 6 is welded onto the small vertical filter body 1;

[0034] One end of the L-shaped rotating tube 7 is rotatably connected to the mounting plate 6;

[0035] The internally threaded tube 8 is welded to the other end of the rotating tube 7, and the internal thread of the internally threaded tube 8 is fitted with a lifting assembly that is welded to the top cover 101.

[0036] Specific implementation of the embodiments of this utility model, such as Figure 1 As shown, the lifting assembly includes a second long screw 9, a mounting block 10, a support plate 11, and a handwheel 12.

[0037] The second long screw 9 is threadedly connected to the internally threaded tube 8.

[0038] The mounting block 10 is welded to one end of the second long screw 9 and the surface of the top cover 101, respectively.

[0039] Several support plates 11 are circumferentially welded to the other end of the second long screw 9;

[0040] The handwheel 12 is welded to the support plate 11.

[0041] To enhance the anti-loosening effect of the earring nut 5, the above embodiment is further optimized by adding a locking element to the earring nut 5. Specifically, the locking element can be a cotter pin, which is not shown in the figure.

[0042] To further facilitate the deflection of the rotating tube 7, the above embodiment is further optimized. A handle is provided on the rotating tube 7, which is not shown in the figure. The purpose is to facilitate the rotation of the rotating tube along the mounting plate after the top cover is removed from the filter, so that the top cover can be moved to the side of the filter without obstructing the subsequent disassembly and cleaning of the filter element.

[0043] The working process of this utility model is as follows:

[0044] First, the nuts and the first long screw 4 are installed according to the external dimensions and operating pressure of the small vertical filter body 1. The nuts are of the easy-tightening type of lug type to facilitate manual operation by the staff. At the same time, the problem of limited wrench operating space and installation difficulty caused by traditional hexagonal bolts is avoided. Meanwhile, several sets of corresponding strip flat steel 2 are welded to the top area of ​​the top cover 101 and the top area of ​​the small vertical filter body 1. With the addition of several first long screws 4 and lug nuts 5, a multi-point firm connection between the top cover 101 and the filter can be achieved. The first long screw 4 is rotated and positioned in conjunction with the mounting base 3. After the lug nuts 5 are separated from it, the first long screw 4 can still be retained on the small vertical filter body 1.

[0045] Meanwhile, the mounting block 10 at the bottom of the second threaded rod is welded to the center of the top cover 101. After all the ear-shaped nuts 5 are removed, the handwheel 12 above the top cover 101 is rotated to raise the top cover 101. During this process, only half a turn of the handwheel 12 is needed to separate the top cover 101 from the filter. Then, a push force is applied manually to deflect the rotating tube 7 along the rotating area of ​​the mounting plate 6, so that the top cover 101 moves to the side of the small vertical filter body 1, and then the subsequent extraction, cleaning and reassembly of the filter element inside the filter can be carried out. After the filter element is cleaned, the rotating tube 7 is rotated again to move the top cover 101 back to the upper area of ​​the filter. Then, the handwheel 12 is rotated in the opposite direction to align the top cover 101 with the upper surface of the small vertical filter body 1 and make a second contact. Finally, the ear-shaped nuts 5 are reinstalled to complete the second assembly between the top cover 101 and the vertical filter, and it can then be used. The disassembly and installation process is more convenient.

[0046] To further improve the load-bearing capacity of the rotating tube 7 and extend its service life, in some embodiments, such as Figure 3 As shown, a sleeve 13 is welded to the small vertical filter body 1, which is located directly below the mounting plate 6. One end of the rotating tube 7 is inside the sleeve 13 and fits against the inner wall of the sleeve 13. The vertical section of the rotating tube 7 passes through the mounting plate 6 and is rotatably connected to the mounting plate 6 through a bearing.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
