Abstract
The utility model discloses an improved extrusion roller of a belt filter press. The outer circumferential surface of the roller is provided with water-permeable holes, the diameters of the water-permeable holes are from 15mm to 20mm, the distance between the adjoining two water-permeable holes are from 30cm to 35cm, and the contact end surfaces of the water-permeable holes are provided with chamfer angles. After the device is adopted, the water-permeable holes are smooth in water permeability when a filter bag is extruded, and the intensity of the roller can completely meet a load generated by extrusion; and the contact end surfaces of the water-permeable holes are provided with the chamfer angles, and the roller is provided with a transition inclined surface at the extruded filter bag, so that the filter bag is hard to scratch. The improved extrusion roller is simple in structure, stable and reliable to work, and convenient to clean and maintain.
Description
Technical field
The utility model relates to the equipment for separating liquid from solid that the phosphate fertilizer industry Industrial Wastewater Treatment is processed, especially a kind of improved belt filter press extruding roller.
Background technology
Separation of Solid and Liquid can effectively be realized in the pressure area of belt filter press, its operation principle is loaded in the filter bag by the screening material, when filter bag pushes through roller, water and slip are extruded out, the following problem of normal appearance during yet reality is produced, the surperficial permeable hole of two extruding rollers is because the little frequent formation dirt layer in aperture, produce and stop up, the water that is filtered off can't pass from permeable hole, directly the both sides from roller spray, pollute neighbouring device and environment, when the end face of permeable hole contacts with filter bag in addition, easily scratch filter bag.
Summary of the invention
For the deficiencies in the prior art part, the utility model aims to provide a kind of improved belt filter press extruding roller, guarantees roller when the extruding filter bag, and permeable unobstructed, filter bag is difficult for damaged.
For solving the problems of the technologies described above, the technical solution adopted in the utility model, a kind of improved belt filter press extruding roller, outer circumference surface at roller is provided with permeable hole, the diameter of permeable hole is 15-20 millimeters, distance between the adjacent permeable hole is 30-35 centimetres, and the contact jaw mask of permeable hole has chamfering.
Adopt said apparatus, permeable hole is permeable unobstructed when the extruding filter bag, and the intensity of roller can satisfy the load that extruding produces fully; Because the contact jaw mask at permeable hole has chamfering, roller has an excessive inclined-plane at the extruding filter bag, is difficult for like this scratching filter bag.
The utility model is simple in structure, and working stability is reliable, the cleaning of cylinder and easy to maintenance.
The accompanying drawing invention
Fig. 1 is the utility model structural representation;
Fig. 2 is the permeable hole structural representation of former cylinder;
Fig. 3 is permeable hole structural representation of the present utility model;
In the accompanying drawing: 1 cylinder, 2 permeable holes, 3 chamferings.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, be provided with permeable hole 2 at the outer circumference surface of roller 1, the diameter of permeable hole 2 is 20 millimeters, and the distance between the adjacent permeable hole 2 is 30 centimetres; This size can guarantee that roller 1 intensity meets the demands, and also can guarantee permeable unobstructed simultaneously.Fig. 2 is the permeable hole structural representation of former cylinder, can find out that in Fig. 2 the edge that the intersection of the permeable hole inner surface of former cylinder and end face forms is sharper, is equivalent to blade, so when the drum extrusion filter bag, easily scratch filter bag; Fig. 3 is permeable hole structural representation of the present utility model, in Fig. 3, is provided with chamfering in the intersection of permeable hole 2 inner surfaces and end face, is equivalent to be provided with a transition inclined-plane, during the drum extrusion filter bag, is not easy to scratch filter bag like this.
