Description

Blender

The blender that the utility model relates to belongs to the chemical medium blender, is to be used for the blender that two or more chemical medium does not have back-mixing specifically.

Existing production diphenyl methane-4,4 '-the used blender of vulcabond, it is still formula agitating device, and the deflection plate in the mix cylinder does not have the oblique angle, its major defect is that various medium incorporation times are long, and back-mixing is serious, mixes inhomogeneous, be difficult to satisfy the requirement that production capacity enlarges and product quality improves, a kind of chemical medium blender quick, no back-mixing has not yet to see.

The purpose of this utility model is intended to improve the deficiency of above-mentioned prior art, provide a kind of for produce diphenyl methane-4,4 '-the used multiple chemical medium of vulcabond fast, no back-mixing blender.

In order to achieve the above object, the utility model is to realize like this, it has support 2, upper end at support 2 connects a motor 20 by bolt 19, lower end at support 2 connects a terminal pad 5 by bolt 3, connect a mix cylinder 8 in terminal pad 5 lower ends, there is a gland 17 mix cylinder 8 tops, there is a medium charging aperture 11 below, survey the wall top one media outlet 6 is arranged, there is a medium charging aperture 10 the sidewall below, the axle of motor 20 is gone up by shaft coupling 1 and is connected a paddle 14, paddle 14 vertically is hung in mix cylinder 8 centers, on the axle of paddle 14 lower ends, a bearing 13 is arranged, at mix cylinder 8 inwalls deflection plate 15 is arranged, be characterized in being provided with mechanical sealing assembly 18 at the paddle axle circumference place of terminal pad 5 and gland 17 junctions, deflection plate 15 bottoms on mix cylinder 8 inner peripheral walls are an oblique angle, paddle 14 is 4 layers, establishes 4 blades for every layer.

The utility model is simple in structure, novel, break existing still formula stirring structure, chemical medium enters from two medium charging apertures, the medium that enters is under the effect of paddle, can mix in a short period of time, realize by means of the special oblique angle of deflection plate again in mixed process, the oblique angle can play the effect of giving dispersion to the little medium of flow, make it and to walk short circuit along certain deflection plate passage, make mixing more even, because MEDIA FLOW is to having adopted unidirectional type, avoided fully the medium that mixes again with the back-mixing of fresh medium, the utility model is to be used for a kind of more satisfactory blender that chemical medium mixes at present.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

The explanation of accompanying drawing drawing:

1 shaft coupling, 2 supports, 3 bolts, 4 bolts, 5 terminal pads, 6 media outlets, 7 flanges, 8 mix cylinders, 9 inlet tube connectors, 10 medium charging apertures, 11 medium charging apertures, 12 flanges, 13 bearings, 14 paddles, 15 deflection plates, 16 bolts, 17 glands, 18 mechanical sealing assemblies, 19 bolts, 20 motors.

In order to understand better and to implement, it is as follows with the accompanying drawing to be that embodiment further specifies below:

Mix cylinder 8 inwalls are welded with deflection plate 15, deflection plate 15 bottoms are cut into the oblique angle, deflection plate 15 is 8, on mix cylinder 8 inwalls, evenly distribute, have below mix cylinder 8 sidewalls medium charging aperture 10, above media outlet 6 is arranged, medium charging aperture 11 is arranged below mix cylinder 8, for the dress watch convenience, medium charging aperture 11 joins with the medium delivery outlet that needs to mix by inlet flange 12, medium charging aperture 10 joins with the medium delivery outlet that needs to mix by inlet tube connector 9, and media outlet 6 connects the medium inlet end that splendid attire mixes by flange 7; By shaft coupling 1 power output shaft of paddle 14 with motor 20 linked to each other, paddle 14 is 4 layers, and every layer 4 blade in mix cylinder 8 central authorities, is installed a bearing 13 in order to prevent the paddle swing in the axial end of paddle 14 lower ends with paddle 14 hangings; Gland 17 is installed by bolt 16 in mix cylinder 8 tops, and a circular hole is stayed in the centre of gland 17, and is convenient in order to clean and overhaul paddle in order to the axle by paddle 14, and terminal pad 5 is connected with mix cylinder 8 dismountings by bolt 4; Do not leak in order to seal inflammable and explosive medium, paddle axle circumference place in terminal pad 5 and gland 17 junctions is provided with mechanical sealing assembly 18, support 2 adopts rigid trestle, connect motor 20 in support 2 upper ends by bolt 19, support 2 lower ends are connected with terminal pad 5 by bolt 3, and whole erection finishes.

Operation principle of the present utility model: motor 20 drives paddle 14 by shaft coupling 1, make paddle reach 1500 rev/mins rotating speed, the big medium of flow enters from the medium charging aperture 11 of mix cylinder bottom, the minimum medium of stream enters from the medium charging aperture 10 on the sidewall, after the paddle stirring through high speed rotating, the medium that enters from these two medium charging apertures can mix in very short time, must realize by means of the special oblique angle of deflection plate 15 in mixed process, the oblique angle can play the effect of giving dispersion to the little medium of flow, make it and to walk short circuit along certain deflection plate passage, make mixing more even, the MEDIA FLOW of this blender has been to having adopted unidirectional type simultaneously, avoided fully the medium that mixes again with the back-mixing of fresh medium.

In addition, this blender adopts advanced self-lubricating type mechanical sealing assembly, avoided leaking outside of interior media fully, motor adopts fire-proof motor, can be used for inflammable and explosive environment, paddle is with 4 layer of 4 blade structure, cooperate the rapid mixing effect that can reach best with the deflection plate around it, the medium charging aperture that flow is little is designed to demountable structure, can carry out dress watch easily, the overall structure of blender is very beneficial for dismounting, maintenance and install, this blender be mix two kinds and two or more chemical mediums a kind of more satisfactory fast, no back-mixing blender.
