The utility model has the advantages of good sealing performance, small size, reasonable gas-liquid distribution and good effect of material dewatering.

Description

The gas-liquid distributor of ceramic filter

Technical field

The utility model is the gas-liquid distributor of ceramic filter.Ceramic filter is a kind of equipment that is used for Separation of Solid and Liquid, now has been widely used in industries such as mine, metallurgy, sewage disposal, and the gas-liquid distributor is the important component part of this filter.

Background technology

It is filter medium that ceramic filter adopts micropore ceramics, uses the capillary absorption principle, reaches the purpose of dewatering efficiency height, good energy-conserving effect, but the gas-liquid distributor is also had higher requirement.Though the principle that the gas-liquid distributor of disc filter cloth filter is in the past used is identical with ceramic filter, poor air-tightness, gas-liquid unreasonable distribution.Gas-liquid distributor to ceramic filter also has indivedual public technologies, but is designed to three chambeies, both complex structures, and dewatering efficiency is low again.This utility model provides a kind of gas-liquid distributor of ceramic filter economically and reasonably, this equipment make the gas-liquid of ceramic filter distribute more reasonable, dewatering efficiency is high, and is simple and reasonable for structure.

Summary of the invention

Gas-liquid distributor by the ceramic filter that the utility model proposes, it is positioned at the roller end of ceramic filter, it is by end flange, end plate, overcoat, dispensing head, the distribution pad, wear-resistant pad, bearing support and seal are formed, end flange by bolting in roller end, the distributing position of one a circle passage of rotating shaft periphery and a circle passage of end flange periphery, quantity is identical with size, and be connected one by one, distribution pad outer end is an end plate, be provided with length at wear-resistant pad near distribution pad one end face periphery, short two annular depressed areas, form two chambeies, when wear-resistant pad and distribution pad are overlapping, the width of this partial circle annular is greater than the diameter of distribution pad upper vent hole, the position enough covers passage, the dispensing head outer end, by bearing support, spring and adjustment bolt and nut withstand fixing at the dispensing head center, at dispensing head, end plate, the overcoat periphery is sealed by seal.

Below in conjunction with the accompanying drawing example the utility model is explained in detail.

Fig. 1 is the host machine part of ceramic filter, (1) shown in the figure is rotating shaft, (2) be cell body, establish 10 disks in the rotating shaft of this example, ceramic wafer (3) is installed on the circumference of 10 disks, each disk perimeter five equilibrium in this example is equipped with 12 fan-shaped ceramic wafers, 10 of same orientation fan-shaped ceramic wafers in the axial direction, 10 of an orientation fan-shaped ceramic wafers have pipeline to be connected on rotating shaft (1) passage in the axial direction, therefore have 12 passages to the end around the axle, 12 holes on the end flange (6) of it and the gas-liquid distributor (4) that is installed in rotating shaft (1) end are corresponding.

The gas-liquid distributor as shown in Figure 2, in rotating shaft (1) end, end flange is fixed with it by bolt (12), the rotating shaft periphery has a circle passage (13), this example is 12, these passages are aimed at one by one with 12 passages of end flange periphery, distribution pad (7) outer end is to forge plate (5), end flange, the circumference external diameter of end plate and overcoat is identical, be provided with length at wear-resistant pad by distribution pad one end periphery, short two annular depressed areas, form two inner chambers, when wear-resistant pad (7) is overlapping, the width in these partial circle ring-shaped depression districts enough covers the circle of one on the distribution pad (7) passage, in the two basic points depressed area, three holes (15) are set respectively, (16), (17), the outer end of dispensing head (10), by bearing support (11), spring (14) and adjustment bolt and nut (18) are fixing, to be used for adjusting the elasticity of dispensing head and distribution pad, in dispensing head (10), the periphery of end plate (5) and overcoat (9) end, seal by seal (19), add the high pressure butter in the seal, seal.As shown in Figure 3, two partial circle ring-shaped depression district orders of valve body are arranged according to this, and slurry and drying stage are promptly inhaled by the b district, d district, local platform and backwash stage at interval.The C district is for discharging is peeled off and the backwash stage.In the utility model, 296 ° of the radians of annular depressed area b--304 °, the radian of c is 28 °---32 °, 28 ° of the radians of d---32 °, inside in two partial circle ring-shaped depression districts is respectively equipped with plurality of tube holes, is three holes (15), (16), (17) in this example, they link to each other with pulp-absorbing pipe (20), drying tube (21) and backwash tube (22) respectively, and go up and the line at dispensing head center and the angle of valve body vertical line are 0 °----4 ° at dispensing head (10) in the center of circle of hole (15).

The specific embodiment:

The utility model has 12 groups of ceramic wafers by group through 4 stage operations, when one group of ceramic wafer runs to the b district, the negative pressure of vavuum pump (23), by lauter tub (24) and pulp-absorbing pipe (20) and drying tube (21), be connected depressed area, b district with (16) by hole (15), passage through end flange (6), the passage of rotating shaft (1) and pipeline lead in the ceramic wafer (3), because vacuum action, ceramic wafer this moment (3) has been filled ore pulp at pulp tank (2) inner surface, and filtrate is delivered to lauter tub (24) by ceramic wafer (3) by pulp-absorbing pipe (20) and drying tube (21), when ceramic wafer produces pulp tank (2), vavuum pump this moment (23) continues the surperficial filtration biscuit that is adsorbed of ceramic wafer (3) is carried out the vacuum suction filtration in the b district by lauter tub (24) and drying tube (21) and hole (16), makes further drying of filter cake.When entering the c district, because no vacuum suction effect, can be easy to be peeled off at the surperficial filter cake material of ceramic wafer (3) and scrape by scraper, finish the process of dehydrating.Water under high pressure enters the backwash district by backwash tube (22), hole (17) when entering the backwash district, pipeline through end flange and rotating shaft carries out backwash to this group potsherd, promptly outwards flow through capillary from the potsherd inner chamber, remove residual material in the capillary, guarantee the high efficiency of next circulation.By the four-stage of gas-liquid separation device, finished the whole work of filtering means dehydration.

The utility model volume is little, good seal, and it is reasonable especially that gas-liquid is distributed, be placed in the working chamber owing to will inhale slurry and drying, pulp absorbing area is increased, in dry section, can help pulp absorbing area to discharge the water that it is not in time discharged, dewatering efficiency is improved, improved filter cake output.
