Description

Technical Field

[0001] This utility model relates to the field of filter plate technology, specifically a visual inspection structure for filter plates and filter cloths. Background Technology

[0002] A filter press is a mechanical device used for solid-liquid separation. It mainly uses pressure filtration to trap solid particles in a suspension on filter cloth or filter plates, while the liquid passes through the filter cloth and is discharged.

[0003] Existing filter cloth testing technologies for filter presses mostly employ the following methods:

[0004] Manual inspection: It requires stopping the machine and disassembling the water nozzle or filter plate to check the state of the filtrate by visual inspection or instruments, which is inefficient and can easily damage the sealing structure;

[0005] Indirect sensor detection: Inferring filter cloth blockage indirectly through pressure and flow sensors has the drawbacks of low accuracy and inability to directly locate the blockage.

[0006] Partially transparent observation window: A small observation window is set on the filter plate, but it is easily affected by the flow rate of the filtrate and air bubbles, which can lead to visual errors.

[0007] Therefore, in view of the above-mentioned problems, this technical solution proposes a visual inspection structure for filter plates and filter cloths. Utility Model Content

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Please see Figures 1-2 A visual inspection structure for filter plates and filter cloth includes a filter plate 1, a quick connector 2, and a transparent tube 3. The side wall of the liquid outlet hole of the filter plate 1 is provided with an external port, which is connected to the transparent tube 3 through the quick connector 2.

[0028] The transparent tube 3 is made of pressure-resistant transparent material, and its inner diameter matches the flow channel of the liquid outlet and extends along the length of the filter plate 1. The pressure-resistant transparent material can be polycarbonate, quartz glass or pressure-resistant plexiglass, etc. The liquid in the transparent tube 3 flows in the same direction and at the same speed as the fluid in the liquid outlet, with no stagnation area. The turbidity of the filtrate, the distribution of bubbles and particles can be displayed in real time. During the filtration process, the filtrate enters the transparent tube 3 through the liquid outlet. The operator can judge the location of filter cloth damage or blockage by observing the state of the liquid in the tube (such as changes in turbidity).

[0029] In this embodiment of the invention, the inner wall of the transparent tube 3 is provided with a spiral guide groove 4 with a pitch of 15 mm and a depth of 0.5 mm. The pitch and depth are only one of the dimensions. The specific design dimensions can be determined according to the size of the liquid outlet hole, filter plate 1, etc., to guide the liquid to form turbulence, reduce sedimentation, reduce liquid adhesion, and enhance fluidity.

[0030] The outer surface of the transparent tube 3 is provided with a longitudinal reflective strip 5 to improve the clarity of observation in conjunction with an external light source (generally used in low-light environments to increase visibility by handheld light source); the longitudinal reflective strip 5 is made of fluorescent material or specular reflective material;

[0031] Quick connector 2 is designed with a snap-fit ​​structure with an elastic sealing ring, which supports quick assembly and disassembly and prevents leakage. The elastic sealing ring is made of fluororubber or silicone rubber.

[0032] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
