Fig. 3 is a modular construction schematic diagram that hangs of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described, as shown in Figure 1, the utility model structure is made of cylindrical shell 7, cone 3, end socket 11, several filter assemblies 8, screen pipe fixed underpan 16, the exhaust outlet 12 that hangs assembly 10, cone defeated mud annular space nozzle 5, shell flange 9, journal stirrup 4, mud discharging mouth 1, inlet 2, liquid outlet 15,

air inlet

6,13,14 and be arranged on the equipment top.

Several screen pipe assemblies 8 are vertically mounted on the screen pipe fixed underpan 16 that is positioned at cylindrical shell 7 bottoms, and are controlled by an assembly 10 that hangs that is arranged on cylindrical shell top, and several filter assemblies form a component cloth and restrain uniformly.As shown in Figure 2, screen pipe assembly 8 is made of cage bone 19, retaining Sponge 18, the compound screen cloth that up and down end plate 20,17, board-like grid row constitute.Upper and lower end plate is all established screw thread, is respectively applied for to connect to hang an assembly and a screen pipe fixed underpan; The cage bone that board-like grid row constitutes is tubular, outer wall covers compound screen cloth, sieve number is decided on filtering accuracy, screen material can be selected by this area general knowledge according to filter medium, tubular retaining Sponge is attached at tubular cage bone inwall, its height is identical with the compound screen cloth that covers screen pipe assembly outer wall, and its thickness is generally 2mm between the 5mm.Screen pipe fixed underpan 16 is made of base, tube connector, liquid outlet, inlet and flange.

Hanging assembly 10 (as shown in Figure 3) is made of cover plate 24, base plate 28, side plate 22, retaining Sponge 23, gas distribution pipe 26, positioning and guiding ring 25, air inlet 13 and ear seat 21 that quantity is identical with the screen pipe assembly.Cover plate, base plate, side plate and several positioning and guiding rings constitute culvert box, and the built-in retaining Sponge of culvert box reaches the gas distribution pipe of structure in the form of a ring, offers on base plate and blows the mud mouth, bore dia at 0.8mm between the 3mm, be made up of several for every group, arrange in the form of a ring, its pitch of holes is consistent with the screen pipe external diameter; Several holes is respectively offered in the form of a ring gas distribution pipe top and bottom, and between the 2mm, quantity is consistent with perforate quantity on the base plate at 0.5mm for bore dia, and gas distribution pipe is positioned at retaining Sponge below, is attached on the base plate, and has less spacing with base plate.

Establish the defeated mud annular space nozzle of cone in the cylindrical shell 7 and the joint portion of cone 3, this nozzle is made of cylindrical shell 7, cone 3, air inlet 6 and annular swash plate 5, leaves annular space between annular swash plate and cone, and supplied gas is passed through.

During work, solids-laden fluid to be filtered is opened the exhaust outlet 12 that is arranged on the top simultaneously with delivery pump inlet 2 these filters of input through being arranged on the cone bottom, makes liquid be full of entire equipment.After finishing above-mentioned action, open the liquid outlet 15 that is arranged on the screen pipe chassis and close exhaust outlet 12, begin to filter, solid particle is held back by screen cloth, and clear liquid passes screen cloth through the liquid outlet outflow filter.Along with the continuity of filter process, filter cake constantly thickens, and pressure drop increases, and (rated designs value) closes infusion pump when pressure drop reaches certain limit, and the pending liquid of the residue in the filter is arranged same original fluid container.Open mud discharging mouth 1, inject the Compressed Gas of certain pressure in the screen pipe assembly, the air-flow that the residual liquid in the retaining Sponge is walked is carried secretly and is atomized, and has diluted filter cake, when air-flow brushes, filter cake is dispelled, blows off.Simultaneously, in hanging an assembly 10, inject Compressed Gas through air inlet 13, hanging the fluid drips that the retaining Sponge in the assembly squeezed out by air-flow falls on the base plate, the air-flow entrained drip, hole on base plate, drip and drench to the screen pipe assembly surface, the filter cake particle that dispels drops down onto cone 3 or mud discharging mouth 1 with air-flow, a pouring liquid, when above-mentioned two processes begin, Compressed Gas enters the defeated mud annular space nozzle 5 of cone through air inlet 6, the filter cake that will fall on cone blows to mud discharging mouth, and with the gas outflow filter.After finishing removal filter cake process, close each air inlet, the filter of cleaning out is stand-by.
