Description

Technical Field

[0001] This utility model relates to the field of ceramic membrane technology, and in particular to a ceramic membrane with a lifting hole. Background Technology

[0002] Existing ceramic membrane modules are difficult to install due to their excessive weight and insufficient toughness of the membrane itself, making them susceptible to breakage from violent impacts. Furthermore, replacing the membrane with a new one is difficult, as is transporting it. Summary of the Invention

[0003] The purpose of this invention is to provide a ceramic membrane with a lifting hole.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A ceramic membrane with a lifting hole includes a front end plate, a rear end plate, and a plurality of filter elements. The front and rear ends of the filter elements are respectively connected to the front end plate and the rear end plate. The front end plate and the rear end plate are hollow in the center and have a lifting groove. The lifting groove has a lifting hole on the outside. The lifting hole opens on the outer end face of the front end plate and the rear end plate. The lifting hole has an internal thread. The inner diameter of the lifting hole is smaller than the inner diameter of the lifting groove.

[0006] Furthermore, the axes of the front end plate and the rear end plate are fixedly connected by a spindle.

[0007] Furthermore, the inner end faces of the front and rear end plates are provided with fixing holes, the fixing holes are provided with internal threads, and the front and rear ends of the spindle are provided with external threads. The spindle and the fixing holes are connected by internal and external thread engagement.

[0008] This invention facilitates hoisting, handling, installation, and membrane replacement by providing threaded lifting holes on the outer surface of the ceramic membrane end plate. The lifting holes can also be used for stress relief. Attached Figure Description

[0016] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] This embodiment discloses a ceramic membrane with lifting holes, such as... Figure 1 As shown, it includes a front end plate 1, a rear end plate 3 and several filter elements 2. In this embodiment, the filter element 2 is a 19-hole filter element. The front and rear ends of the filter element 2 are connected to the front end plate 1 and the rear end plate 3 respectively. The filter element 2 is inserted and fixed in the front end plate 1 and the rear end plate 3 along the front-to-back direction.

[0018] The front-end board 1 and the rear-end board 3 have the same structure, such as Figure 2 As shown, the front end plate 1 includes a first end plate 101, a first connecting plate 102, a second end plate 103, a second connecting plate 104 and a third end plate 105 arranged sequentially from front to back. The first end plate 101, the second end plate 103 and the third end plate 105 have the same outer diameter. The first connecting plate 102 and the second connecting plate 104 have the same outer diameter and are smaller than the outer diameter of the first end plate 101.

[0019] Sealing rings 106 are respectively fitted onto the outer sides of the first connecting plate 102 and the second connecting plate 104. The two sealing rings 106 are tightly fitted with the gaps between the first end plate 101 and the second end plate 103, as well as the gaps between the second end plate 103 and the third end plate 105.

[0020] The first end plate 101 has a cylindrical lifting groove in the center of its hollow interior. The outer side of the lifting groove has a cylindrical lifting hole 4. The lifting hole 4 opens at the outer end face of the front end plate 1 and the rear end plate 3. The lifting hole 4 has an internal thread. The front end plate 1 and the rear end plate 3 can be lifted by connecting the external bolt to the lifting hole 4. The inner diameter of the lifting hole 4 is smaller than the inner diameter of the lifting groove. The front end plate 1 and the rear end plate 3 can be lifted by extending a movable hook into the lifting groove.

[0021] like Figure 3 As shown, the front end plate 1 and the rear end plate 3 are fixedly connected by the spindle 6. The inner end face of the shaft of the third end plate 105 is provided with a fixing hole 5, which is provided with an internal thread. The front and rear ends of the spindle 6 are provided with external threads, and the spindle 6 and the fixing hole 5 are connected by the internal and external threads.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
