Description

The pressure ceramic filter of a kind of working region sealing

Technical field

The utility model relates to a kind of working region sealing continous way pressure ceramic filter, specifically, relate to working region (ore pulp cell body, filter and discharge system) sealed, with the micropore ceramics material is filter medium, and the pressure differential (can reach 0.6MPa) of utilizing compressed air (or compressed air and vacuum draw act on simultaneously) to be produced realizes the ceramic filter that filters.Be a kind of energy-efficient shape solid-liquid separating equipment, be applicable to fields such as black, non-ferrous metal ore, thin fine coal powder, chemical industry, food and sewage disposal.

Background technology

The vacuum ceramic filter is a kind of advanced person's a solid-liquid separation mechanics, its capillarity of utilizing negative pressure of vacuum and micropore ceramics material to be had realizes filtering (its micro-pore diameter is about 1.5 μ m), it is advanced in performance to possess skills, energy-saving and cost-reducing, advantages such as clean environment firendly, at present, the trend of the high traditional filter cloth formula filter of progressively alternative energy consumption is arranged in applications that put it over of the Separation of Solid and Liquid of industries such as ore dressing, chemical industry, nonmetallic materials, metallurgy.But because vacuum filtration maximum filtering pressure reduction is an atmospheric pressure, make the use of vacuum ceramic filter be subjected to severely restricts, especially the regional vacuum of forcing down at the height above sea level atmosphere only is 0.06MPa.Filtering that solid contents is low, material thin and slip viscosity when big, having that production capacity is low, the high problem of filter cake moisture, having a strong impact on the expansion of ceramic filter application.

The described flotation concentrate pressing filter of ZL95217603.3 that Patent Office of the People's Republic of China (PRC) was authorized on March 13rd, 1996, be that traditional disk filter integral body is wrapped into pressurizing vessel, the very huge heaviness of complete machine, filter medium adopts stainless (steel) wire (weaving of employing filter cloth is also arranged in actual the enforcement), filter opening diameter big (＞12 μ m), it is serious that thin material is worn filter, and the suspension content height must return production procedure and handles in the filtrate, increase the weight of the load of whole production flow process, increased the production run cost.

On July 19th, 2006, application number 200620124082.1 was to adopt ceramic filter integral body is wrapped into pressurizing vessel by the pressure ceramic filter patent of our company's application, and equipment volume is big, and high material consumption is used the energy consumption height, is unfavorable for Operation and Maintenance.

Summary of the invention

The objective of the invention is to adopt working region partial closure mode to dwindle the required pressurization space of complete machine sealing, reduced material consumption significantly and alleviated complete machine weight, reduced the work energy consumption, be convenient to Operation and Maintenance.The pressure that utilizes compressed air (or compressed air and vacuum draw act on simultaneously) to be produced is realized filtering, and comparable conventional vacuum ceramic filter improves nearly ten times of pressure differentials.With the micropore ceramics material is filter medium, makes the ceramic filter function adapt to the filtration of high altitude localities and various high-viscosity materials.It can increase substantially the production capacity of filter, reduces filter cake moisture, realizes disposable Separation of Solid and Liquid, reduces filter production run cost, improves the adaptive capacity of filter to material, expands its application.

For realizing purpose of the present invention, pressure ceramic filter provided by the invention comprises pressurization storehouse 1, the ore pulp cell body 2 of ceramic filter, filter 3 (plug-in type assembling mode, Fig. 8) and discharge system place the pressurization storehouse, discharge system in filter area less than 16m ²Shi Caiyong hopper 4 blankings are greater than 16m ²The time by solid material conveyer 5 (other conveyers such as drag conveyor or spiral); By the sealing movingly between axle sealing system 6 (Fig. 7) realization pressurization storehouse and rotating spindle; Solid material drain valve 7 is arranged and is connected in pressurization storehouse outer setting, under the situation that keeps the storehouse internal pressure not leak, the solid material of hopper 4 or conveyer 5 conveyings is discharged to outside the storehouse on the belt conveyor with the pressurization storehouse; Middle trough 8 is set, mortar pump 9 is used for the filtration slip is fed the ceramic filter cell body with certain pressure; Moisture trap 10, vavuum pump 11 and low pressure gasholder 12 are set, air compressor machine provides power for filtration; Circulating pump 13, measuring pump 14 and associated pipe, pipe fitting are set, are used for the backwash and the regular cleaning and regeneration of filtrate discharge, ceramic filter plate, to keep its production capacity; Hydraulic Station 15 is set is used to open and close solid material drain valve 7, air compressor machine, high pressure tank 16 are set are used for solid material drain valve 7 sealing air feed; Automatic control system 17 is set is used for complete machine control and failure warning automatically.
