Embodiment Construction

[0012] see figure 1 , figure 2 Shown, the fuselage of filter machine of the present invention is made up of upper cavity 14 and lower cavity 17, is welded with dirty liquid inlet 1 and dirty liquid outlet 2 on upper cavity 14, is welded with clean liquid outlet on lower cavity 17 11. The upper cavity 14 and the lower cavity 17 are welded as a whole, and the middle fixed welding mesh plate 16 divides it into two upper and lower cavities. The filter cloth 15 is arranged on the mesh plate 16 , and side holes are correspondingly arranged on the two side walls of the connection between the mesh plate 16 and the upper cavity 14 , and the side holes are used for passing the filter cloth 15 . Install the sealing bracket 4 outside the upper cavity 14, the sealing bracket 4 is provided with a sealing strip 5, the sealing strip 5 corresponds to the side wall and the position of the side hole of the upper cavity 14, and a compression cylinder is installed on the sealing bracket 4 3. A...

Abstract

The invention discloses a thickening and dewatering filter comprising an upper cavity and a lower cavity and being characterized in that a meshed pore plate is arranged between the upper cavity and the lower cavity; the upper cavity, the meshed pore plate and the lower cavity are fixedly connected to form an integrated structure; filter cloth is arranged on the meshed pore plate; two opposite sides of a connection part of the upper cavity and the meshed pore plate are provided with side holes; the filter cloth extends out of the side holes; a sealing bracket is arranged out of the upper cavity; a sealing bar is arranged on the sealing bracket; the sealing bar corresponds to the side wall of the upper cavity and the side holes; and a compacting cylinder is connected to the sealing bracket. Compared with the prior art, the thickening and dewatering filter provided by the invention is composed of the integrated upper cavity and lower cavity, namely the upper cavity and the lower cavity are integrated, the meshed pore plate is used as a demarcation line between the upper cavity and the lower cavity, and the pressures in the cavities are controlled by the sealing bracket arranged at the side, so that the thickening and dewatering filter has the following advantages that control elements are reduced, the equipment structure is simpler and is optimized, the filter is convenient to operate, and meanwhile, the purposes of energy saving and emission reduction are achieved.

Description

technical field [0001] Concentrated dehydration filter is widely used in the filtration of cooling lubricant (oil) in high-precision machining processes such as steel rolling, grinding, and grinding, so as to improve the processing technology, improve the surface processing quality of workpieces, and prolong the service life of cooling lubricant (oil) , and can also be used in the field of environmental protection. The invention provides a concentrated dehydration filter with improved structure. Background technique [0002] The concentrated dehydration filter is a new type of filtration product. It uses a recirculating filter belt as the medium to arrange the sewage on the filter medium, and makes full use of the gravity of the sewage itself and the positive pressure difference between the upper and lower chambers to achieve solidification. Liquid separation, the dirty liquid accelerates through the filter medium to form a filter cake, and then the filter cake also partici...
