Embodiment 1

[0017] A high-efficiency washing filter plate, which is composed of the innovatively designed washing plate 13 and the blind washing half of the blind plate 12. It is commonly known as the blind washing half filter plate. Integrated filtration and washing, light and dark double flow, two-way washing function. The washing plate 13 has a washing function, and is mainly provided with a liquid outlet confluence channel 2, a filtrate outlet hole 3, a filter plate sealing edge 4, a filter plate feeding hole 5, a filter plate support point 6, a filter plate filter surface 7, a filter plate Plate four-corner holes 8, filter plate plugs 9; it is characterized in that the lower two corners of the existing washing plate are improved into dark flow holes; Changing to the four-corner undercurrent form avoids the need to manually close the open flow nozzle before washing, and simplifies the manual operation, which is conducive to improving the automation level of the filter press. The blin...

Embodiment 2

[0020] A filtering and washing method for high-efficiency washing filter plates uses the integrated filtering and washing mechanism formed by the high-efficiency washing filter plates of the present invention. Closing valve 15, filter cloth 16, etc.; the washing method is two-way cross washing, and the liquid outlet method is innovated as an efficient light and dark double outflow form. image 3 The schematic diagram of the washing method (process flow) of the high-efficiency washing filter plate is described.

[0021] When feeding (static filtration), all valves 11 are opened, open flow and dark flow are double effluents, and the feed hole 5 is pumped into the slurry with a high-pressure pump for low-pressure static filtration. The filter cake is formed in the chamber; the filtrate converges to the liquid outlet channel 2 through the filtrate outlet hole 3, and then flows out from the four corner holes 8 on the washing plate 13, or it can also converge to the liquid outlet ch...

Abstract

The invention discloses an efficient washing filter plate and a filtering and washing method thereof and belongs to the technical field of pressure filtration equipment and processes in the solid-liquid separation process. The efficient washing filter plate is formed by a washing plate (main plate) and a blind plate (auxiliary plate) through half-and-half matching and is called 'blind and washinghalf-and-half filtering plate'. The efficient washing filter plate is characterized in that double blind holes in lower two corners of an existing washing plate and blind plate are improved into through holes, and double open flow discharging forms of the existing washing plate are innovated into open and dark double flow (blind plate double open flow and washing plate four corner dark flow) discharging form, so that the filter plate has functions of integrated filtering and washing, open and dark double flow and bidirectional cross washing. According to the filtering and washing method of theefficient washing filter plate, the efficient washing filter plate adopts a bidirectional cross washing manner, and the discharging manner is innovated into an efficient open and dark double flow manner. The pioneered efficient washing filter plate and filtering and washing method thereof have the advantages of high discharging speed, short feeding time and high filtering and washing efficiency,the filtering and washing efficiency is improved, and the automatic basis of a filter press is consolidated.

Description

technical field [0001] The invention belongs to the technical field of pressurized filtration equipment and technology in the solid-liquid separation process, and relates to a washing filter press and a filtering and washing method thereof. Background technique [0002] The filter press is a general intermittently operated pressurized filtration equipment, and the washing filter press is a filter press integrating filtration and washing, which is suitable for solid-liquid separation of various suspensions. The washing filter press is mainly composed of a frame, a pressing mechanism, a filtering and washing mechanism, a plate pulling mechanism, a hydraulic drive mechanism, and an electrical control system. into each filter chamber for low-pressure static filtration; the particles in the material retained by the filter cloth form a filter cake in the filter chamber; the water pump injects the washing liquid into the filter cake crosswise from the washing holes at the two corne...
