Abstract
The utility model discloses a pressing roll device of a rotary drum type vacuum filter. Two ends of a pressing roll (10) of the pressing roll device (6) are connected with pressing roll shafts (9), the pressing roll shafts (9) are supported on bracket arms (8) via bearings (13), the other ends of the bracket arms (8) are connected to bearing blocks (7) via pins (12), the bearing blocks (7) are fixed on a frame (4), and the outer surface of the pressing roll (10) is covered with a modified nylon layer (11). The modified nylon layer (11) has higher anticorrosion and wear-resistant performance so that the service life of the pressing roll device (6) can be prolonged effectively, the pressing roll (10) can rotate more smoothly, and surfaces of filter cakes can be more flattened after rolling. Accordingly, a scraper cleaning device can be omitted completely, structure of the filter can be simplified, costs for manufacturing, running and maintenance are reduced, and various defects caused by use of the scraper cleaning device are overcome effectively.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of filter, is specifically related to a kind of press-roller device of vacuum-type drum filter.
Background technology
Outer filtering surface rotary drum vacuum filter is widely used in industries such as chemical industry, metallurgy, food, petroleum refining, papermaking and wastewater treatment.Its operation principle is: the rotation rotary drum of laying filter medium is immersed in the filter pulp groove of certain liquid level, the rotary drum space is divided into several compartments by the radial rib sheet, each compartment with independent hole link to the dispensing head of axle journal, pass through quiet, the moving cross gas plate of dispensing head by the corresponding pipeline of motionless valve seat, to each compartment of rotary drum extracting vacuum, other medium such as input compressed air etc. in certain sequence, guarantee that each compartment finishes filtration successively, washs, takes off operations such as liquid, removal filter cake and filter cloth regeneration.
In order to increase the production capacity of filter as far as possible, guarantee product quality, reduce energy consumption, require rotary drum filter medium surface to form and try one's best thick and uniform cake layer.In the rotary drum outside, the function of the pressure roller parallel with the rotary drum axis is: the filter cake on the smooth rotary drum periphery filter medium, with filter cake flatten, compacting, help aspiration vacuum filter cake further carried out drying, prevent from simultaneously to cause vacuum leak because filter cake ftractures.The pressure roller of traditional structure (stainless steel or cast iron) surface, very easy bonding moist press cake, therefore must need increases the scraper cleaning plant, clears up the filter cake of roller surface bonding at any time, has increased manufacturing cost and operation maintenance workload.The cutting edge of cleaning scraper is close to the pressure roller working face for a long time, makes the pressure roller working face produce more serious wearing and tearing, has reduced the pressure roller task performance, has shortened the service life of pressure roller; Scraper behind the uneven wear can not fully be removed the bonding filter cake on the pressure roller, causes roller surface uneven, not only can not smooth filter cake, and destroy the filter cake surface quality on the contrary, even caused loss of vacuum; Simultaneously, the pressure roller body corrosion resisting property of traditional structure is poor, and the service life of pressure roller body is shorter, and existing apparatus as shown in Figure 4.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of press-roller device of vacuum-type drum filter of simple in structure, function admirable is provided.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of press-roller device of rotary drum vacuum filter, comprise that the rotary drum that dispensing head is housed is bearing on the frame by its two end axles neck, and be arranged in the filter pulp groove, frame also is equipped with drive unit, and press-roller device is installed in the rotary drum top, and the pressure roller body two ends in this press-roller device are connected with pressure roller shaft, pressure roller shaft is bearing on two trailing arms by bearing, the trailing arm other end is connected on the bearing block by bearing pin, and bearing block has coated the modified nylon materials layer by being bolted on the frame on the pressure roller external surface.
Further technical scheme is that described modified nylon materials layer can be one or several combinations that strengthen in nylon, tenacity increased nylon, wear resistant nylon, halogen-free reinforced nylon, conduction nylon or the fire-retardant nylon.
Compared with prior art, the beneficial effects of the utility model are:
By the modified nylon materials layer in this device extremely strong corrosion-resistant and anti-wear energy is arranged, can prolong the service life of press-roller device effectively; The modified nylon materials laminar surface is compared the much bigger of traditional structure with the frictional force of filter cake, and it is more smooth and easy that the pressure roller body is rotated, and the filter cake surface is more smooth after the roll extrusion, and the filter cake quality improves, and vacuum leak reduces.Owing to cancelled the scraper cleaning plant, simplified filtering machine structure, reduced manufacturing cost and during-operation service cost, overcome all disadvantages that the scraper cleaning plant produces simultaneously effectively.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model structure left side schematic diagram.
Fig. 3 is the utility model locations of structures schematic diagram.
Fig. 4 is the utility model existing structure schematic diagram.
Among the figure: slurry tank 1, drive unit 2, dispensing head 3, frame 4, press-roller device 5, rotary drum 6, bearing block 7, trailing arm 8, pressure roller shaft 9, pressure roller body 10, modified nylon materials layer 11, bearing pin 12.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As Fig. 1, Fig. 2 and shown in Figure 3, rotary drum 6 is bearing on the frame 4 by its two end axles neck, and be immersed in the filter pulp groove 1 of certain liquid level, drive unit 2 drives rotary drum 6 rotations, the dispensing head 3 that is communicated with rotary drum 6 is connected vacuum system, the filter pulp that rotary drum 6 is drawn in the filter pulp groove 1 forms certain thickness cake layer at rotary drum 6 external peripheral surfaces.Press-roller device 5 is installed in rotary drum 6 tops, and its center line is parallel with rotary drum 6 center lines; Pressure roller body 10 two ends in this press-roller device 5 are connected with pressure roller shaft 9, pressure roller shaft 9 is bearing on two trailing arms 8 and can rotates freely by bearing 13, trailing arm 8 other ends are connected on the bearing block 7 by bearing pin 12, bearing block 7 is by being bolted on the frame 4, trailing arm 2 can drive pressure roller shaft 6 and swing around bearing pin 12 with pressure roller body 10, coated modified nylon materials layer 11 on pressure roller body 10 outer surfaces, the modified nylon materials layer 11 in the present embodiment is for strengthening nylon.Because the reason of gravity, pressure roller body 10 can be pressed on the rotary drum 6 lip-deep filter cakes at any time, and pressure roller body 10 is owing to the frictional force of filter cake is rotated, and the dependence self gravitation flattens, the compacting filter cake, make the cake layer on rotary drum 6 surfaces evenly smooth, help further dehydrating of filter cake.
