Abstract

The utility model provides a novel banbury mixer end powder device, the scheme is, including setting up shaft hole periphery and the ring channel that the shaft hole meets in banbury mixer machine wall, set up the antifriction plate in the ring channel, the antifriction plate be equipped with the endless oil groove around the shaft hole on banbury mixer machine intramural side, be equipped with the first oil filler point of intercommunication endless oil groove on banbury mixer machine wall and the antifriction plate, the antifriction plate on the intramural lateral wall of banbury mixer machine axially hole circle zhou junbu have a plurality of oil distributing groove, oil distributing groove communicates the endless oil groove. The utility model discloses a reform transform former banbury mixer, avoided the tradition end the powder device in lubricating oil can't be to A the A passageway carries out the sufficient lubrication, blockades completely, does in a single day the powder get into A the B section just can form outer the hourglass, spill from D, at B under the two end face seal unfavorable conditions of B, spill hourglass in forming from the C point, the utility model discloses but greatly reduced tradition shaft seal device 's material requires and assembles the precision, prolongs the replacement cycle of wear ring greatly, and economy is suitable for.

Description

A kind of novel banbury stops powder device

Technical field

The utility model relates to banbury and stops powder device, and a kind of inserted, straight-through lubricity stops powder discharger.

Background technology

Banbury is one of equipment important in press production line, and powdery PVC blended stock is the most size-reduced, pinch Close, longitudinally cut and return, laterally folded action, under high pressure, the condition of high temperature, complete gel (plasticizing), in plasticizing process, powdery mixes Easily spilling with material, banbury leakage powder (expecting) approach has two kinds, interior leakage and leaking outside.Blended stock under high pressure enters shaft end face (having 30-170 silk gap) with in panel wearing plate gap on machine wall, A-A in figure, through wear ring cylindrical and wearing plate endoporus (there are 100 gaps in gap), i.e. A-B, and then, the extruded stock spilt divides again two-way, and a road is outside machine wall endoporus is with envelope material copper ring Circle gap (having 50 gaps) forms the i.e. B-D that leaks outside, and another road forms interior leakage through wear ring end face with envelope material copper ring end clearance I.e. B-C, traditional only powder (leak-stopping) device is hydraulic type Castor Oil mechanical shaft seal, and its operation principle is set in machine for envelope material environment In cinclides, under oil pressure effect, envelope material ring end face is close to hot jacket wear ring end face on shaft, and envelope material ring, oilhole A are external Extreme pressure lubricant, arrives in envelope material ring end face oil groove, and wear ring can be lubricated by extreme pressure lubricant with envelope material ring both ends of the surface, resistance to Bull ring rotates with shaft, and for rotating ring, envelope material ring does not rotates, and for stationary ring, sufficient in oil mass, dynamic and static ring contacts under good situations, Parts of lubricating oil is through B-A passage, under extruding and centrifugal action, gets rid of to A-A passage, first the passage block that will leak outside Living, the shortcoming of this device has: 1) wear ring and envelope material ring material require high, expensive 2) wear ring hot jacket is on shaft Assembly precision require higher by 3) installation accuracy of envelope material brasses (envelope material ring) requires higher by 4) if above three it cannot be guaranteed that, profit A-A passage cannot be lubricated by lubricating oil, more cannot block, the first line of defence of leak-stopping cannot complete 5) wear ring abrasion after more Quantities big 6 when changing) machine wall is monoblock type, in A-A passage, the maintenance after machine wall weares and teares of burnt material or stirring axial terminal is laborious high, Time is long.

Utility model content

For above-mentioned situation, for overcoming the defect of prior art, the utility model provides a kind of novel detachable, straight-through The wearing plate of lubricating oil, it is peripheral that wearing plate is embedded in machine wall endoporus.

The technical solution of the utility model is, including being arranged on the annular that axis hole periphery in banbury machine wall connects with axis hole Groove, arranges wearing plate in cannelure, described wearing plate on the side in banbury machine wall, be provided with ring-type oil around axis hole Groove, described banbury machine wall and wearing plate are communicated with the first oil filler point of endless oil groove, and described wearing plate is towards banbury It is evenly distributed in multiple spreader groove, described spreader groove connection endless oil groove around axis hole on sidewall in machine wall.

The utility model is to transform former banbury, it is to avoid in tradition only powder device, A-A cannot be led to by lubricating oil Road carries out sufficient lubrication, completely closes off, and powder once enters section A-B, will be formed and leak outside, spill at D, in B-B both ends of the surface In the case of poor sealing, spill from C point, leakage in being formed.The utility model simple in construction, can be substantially reduced tradition gland seal device Material requires and assembly precision, is greatly prolonged the replacement cycle of wear ring, economic and practical.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

As shown in Figure 1 to Figure 3, in the utility model includes being arranged on banbury machine wall 1, axis hole 2 periphery connects with axis hole 2 Cannelure 3, wearing plate 4 is set in cannelure 3, described wearing plate 4 towards on the side in banbury machine wall 1 around axis hole 2 are provided with endless oil groove 5, and described banbury machine wall 1 and wearing plate 4 are communicated with the first oil filler point 6 of endless oil groove 5, described Wearing plate is evenly distributed in multiple spreader groove 7 around axis hole 2 on the sidewall in banbury machine wall 1, and described spreader groove 7 connects Endless oil groove 5.

Described spreader groove 7 is curved, and its arc opening direction is consistent with shaft 11 direction of rotation.

The utility model is on the basis of original tradition gland seal device, and it inlays wearing plate 4 in machine wall endoporus periphery, resistance to Nog plate 4 is made up of 40cr, quenched process, and intensity is high, and wearability is good, and wearing plate 4 faces and has oil storage on the end face in machine wall Groove and circular arc spreader groove 7, multiple change arc spreader groove in the shape of a spiral, and the extreme pressure lubricant injected from the first oil filler point 6 is permissible A-A passage carries out abundant fuel feeding, and ginseng forms oiliness pastel after having a small amount of powder mixture, has on the one hand blocked A-A and has leaked powder Passage, on the other hand, when A-A gap is less, Castor Oil both ends of the surface, it is to avoid dry friction, the endless oil groove of described wearing plate is even Logical first oil filler point 6, is wherein passed through the adjustable extreme pressure lubricant of fuel delivery, and described spreader groove is the cloth oil that can be thrown away by oil plant Groove.

As in figure 2 it is shown, spreader groove helically formula, when pasty state material rotates with shaft in A-A gap, at spiral cloth Under hopper centrifugal action, pastel is centrifugal throws away A-A region, places pastel and enters B-D and B-C from A-A.
