Description
Technical Field
The utility model relates to a pressure filter diaphragm field of making, concretely relates to pressure filter rubber diaphragm.
Background
Along with the promotion of the requirement on environmental protection at home and abroad, the requirement on filter press equipment for a sewage treatment system is higher and higher, and the requirement on the water content of a filter cake is higher and higher correspondingly.
Due to the influence of the manufacturing level of the domestic rubber diaphragm, most domestic filter presses do not use the rubber diaphragm which can better reduce the water content of a filter cake. The existing equipment can not meet the market demand.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defects of the prior art, the present invention aims to provide a rubber diaphragm for a filter press.
A filter press rubber diaphragm comprising:
the membrane body is characterized in that a plurality of cylindrical membrane sheets are arranged at the upper end of the pressure surface of the membrane body, the middle of the pressure surface of the membrane body is provided with at least one filter tank close to the edge, the filter tank comprises a filter tank bottom and a filter tank surface, the filter tank surface is an inclined plane, the two ends of the membrane body are provided with a first supporting structure and a second supporting structure, and the first supporting structure and the second supporting structure are connected with the pressure surface of the membrane body.
In a preferred embodiment of the present invention, a plurality of reinforcing ribs are disposed around the diaphragm body.
In a preferred embodiment of the present invention, the rubber diaphragm of the filter press is made of nitrile rubber.
The beneficial effects of the utility model reside in that:
the utility model discloses a pressure filter rubber diaphragm adopts the inflation design, makes its bulging deformation extrusion filter cake in order to reduce filter cake moisture through aerifing to pressure filter rubber diaphragm is inside. The structure of the rubber diaphragm of the filter press can ensure that the filtrate is fully contacted with the diaphragm, thereby increasing the working efficiency.

Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The rubber diaphragm of the filter press as shown in fig. 1 or 2 comprises a diaphragm body 100, wherein a plurality of cylindrical diaphragm sheets 120 are arranged at the upper end of a pressure surface 110 of the diaphragm body 100, the cylindrical diaphragm sheets 120 are arranged in the middle of the pressure surface 110 of the diaphragm body 100, and a plurality of reinforcing ribs 101 are arranged around the diaphragm body 100.
The material of the rubber diaphragm 100 of the filter press is nitrile rubber. Different rubber materials can be selected according to different characteristics of various fluids of the gate valve, so that different performance requirements are met.
The filter tank 130 is arranged on the edge of the pressure surface 110 of the membrane body 100, the filter tank 130 comprises a filter tank bottom 131 and a filter tank surface 132, the filter tank surface 132 is an inclined surface, the two ends of the membrane body 100 are provided with supporting structures 102 and 103, and the supporting structures 102 and 103 are connected with the pressure surface 110 of the membrane body 100 to leave a space inside the whole membrane body 100.
The utility model discloses a pressure filter rubber diaphragm adopts the inflation design, makes its bulging deformation extrusion filter cake in order to reduce filter cake moisture through aerifing to pressure filter rubber diaphragm is inside. The structure of the rubber diaphragm of the filter press can ensure that the filtrate is fully contacted with the diaphragm, thereby increasing the working efficiency. The service life can be up to several years. The technical index is about 5% -10% higher than that of foreign similar products, thereby greatly reducing the equipment maintenance cost, reducing the maintenance time and reducing the maintenance cost.
