Description

Technical Field

[0001] The utility model belongs to the technical field of diaphragm plates, and particularly relates to an inlaid card slot type diaphragm plate component. Background Art

[0002] The diaphragm filter press is one of the most common filter presses, and its diaphragm plate assembly includes a diaphragm plate and a diaphragm sheet. In the prior art, the diaphragm plate and the diaphragm sheet are generally integrated, that is, the two cannot be disassembled, which leads to a big problem that no matter which part is damaged, it needs to be replaced as a whole, resulting in high maintenance costs.

[0003] At present, there are also some detachable diaphragm plates and diaphragm sheet structures in the prior art, such as a slot-type structure, but this structure currently requires auxiliary fixation. For example, patent CN109364543A discloses a diaphragm of a filter press diaphragm filter plate and a filter press diaphragm filter plate using the diaphragm filter plate;

[0004] It adopts a card slot structure, but in order to prevent it from falling out, a diaphragm pressure plate needs to be set for auxiliary fixation. The diaphragm pressure plate is assisted by a circle of bolts to complete the auxiliary fixation. This method is not convenient for disassembly and the disassembly efficiency is low. Utility Model Content

[0005] The utility model provides an inlaid card slot type diaphragm plate component, which can solve the problems pointed out in the background technology.

[0006] A recessed card slot type diaphragm plate assembly comprises a diaphragm plate and a diaphragm sheet, wherein the edge of the diaphragm sheet is provided with a first connecting protrusion for sealing connection, the first connecting protrusion is provided with an anti-slip protrusion, and the diaphragm plate is provided with a first limiting groove that matches and cooperates with the first connecting protrusion and the anti-slip protrusion.

[0007] Preferably, a diaphragm liquid outlet slot is provided at the edge of the diaphragm sheet, and a pressure plate is connected to the diaphragm liquid outlet slot.

[0008] Preferably, the pressure plate is detachably connected to the diaphragm plate.

[0009] Preferably, the pressure plate is provided with a second connecting protrusion, and the diaphragm plate is provided with a second limiting groove that cooperates with the second connecting protrusion.

[0010] Beneficial effects: The utility model provides an inlaid card slot type diaphragm plate assembly, the diaphragm sheet and the diaphragm plate adopt a card slot type connection design and are provided with an anti-slip protrusion, so that it is easy to disassemble, replace and maintain, saving maintenance costs;

[0011] The pressure plate is provided to reinforce the connection of the diaphragm;

[0012] In addition, the pressing plate protects the diaphragm here, preventing the water flow from directly flushing the diaphragm, thus extending the service life of the diaphragm. Moreover, the pressing plate is designed as a detachable card slot type, which is convenient for individual replacement. That is, generally only the pressing plate needs to be replaced, without replacing the entire diaphragm, which also saves the maintenance cost. Brief Description of the Drawings

[0016] Reference numerals in the figure: diaphragm plate 1; first limiting groove 11; second limiting groove 12; diaphragm 2; first connecting protrusion 21; anti-disengagement protrusion 22; diaphragm liquid outlet groove 23; pressing plate 24; second connecting protrusion 25. Detailed Embodiments

[0017] The following will describe in detail a specific embodiment of the present utility model with reference to the drawings. However, it should be understood that the protection scope of the present utility model is not limited by the specific embodiment.

[0018] Embodiment 1: As Figure 1-2 shown, an inlaid card slot type diaphragm plate assembly includes a diaphragm plate 1 and a diaphragm 2. The edge of the diaphragm 2 is provided with a first connecting protrusion 21 for sealing connection. The first connecting protrusion 21 is provided with an anti-disengagement protrusion 22. The anti-disengagement protrusion 22 can be a triangular protrusion and can be arranged on both sides of the first connecting protrusion 21. The diaphragm plate 1 is provided with a first limiting groove 11 that fits and cooperates with the first connecting protrusion 21 and the anti-disengagement protrusion 22. By providing the anti-disengagement protrusion 22, it is possible to cancel the use of a diaphragm pressing plate for fixation, making the disassembly and installation process of the entire diaphragm 2 faster and more convenient.

[0019] Embodiment 2: As Figure 1-2 shown, in this embodiment, a diaphragm liquid outlet groove 23 is provided at the edge of the diaphragm 2. A pressing plate 24 is connected to the diaphragm liquid outlet groove 23, and the pressing plate 24 is detachably connected to the diaphragm plate 1.

[0020] Specifically, the pressing plate 24 is provided with a second connecting protrusion 25, and the diaphragm plate 1 is provided with a second limiting groove 12 that cooperates with the second connecting protrusion 25.

[0021] The above discloses only several specific embodiments of the present utility model. However, the embodiments of the present utility model are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
