Description

Bitumenpump

Technical field

The utility model belongs to the industrial pump technical field, particularly a kind of bitumenpump.

Background technique

The bitumenpump flow passage components of Shi Yonging are many in the market, damage easily in the using process, just dismantle inconvenience during maintenance, and maintenance cost height, and material is lossless big does not in use have insulation effect for the material of the certain specified temp of needs.

Summary of the invention

The utility model main purpose is in order to address the above problem, provide that a kind of flow passage components are few, few easy workout part, can onlinely dismantle, amount of maintenance is little, and material loss is little, can play the bitumenpump of insulation effect.

In order to achieve the above object, the technological scheme that the utility model provides is: a kind of bitumenpump, and it comprises driving shaft, bearing housing, support, the pump housing, driving wheel, follower, swing link, pump head and driven shaft; Bearing housing is installed in the rear portion of support, and the front end of support is connected with the pump housing; Pump head is installed in the front end of the pump housing; Driving wheel, follower, swing link and driven shaft are installed in the pump housing; Driven shaft is fixed on the pump head; Follower is placed on the driven shaft; Driving shaft runs through bearing housing, support and the pump housing; Driving wheel is placed in the driving shaft front end; Also have export and import on the pump housing; The radius of follower is less than the radius of driving wheel; Follower places driving wheel inside, and driving wheel and follower mesh in the outlet port of the pump housing; The relative position of driving wheel and follower engagement place also is equipped with swing link between driving wheel and the follower; Chuck is opened on support;

This bitumenpump also comprises rack sleeve; Rack sleeve is installed on the front end of support, is placed in the driving shaft outside;

Rack sleeve is that wear-resisting, high temperature material is made;

This bitumenpump also comprises driven axle sleeve; Driven axle sleeve is installed between driven shaft and the follower;

Driven axle sleeve is that wear-resisting, high temperature material is made;

This bitumenpump also comprises lock nut and lock washer; Lock nut is installed in the joint at driving shaft and bearing housing rear portion by lock washer;

In the chuck is freezing mixture or heating agent.

When the utility model used, material entered the pump housing from inlet, and driving wheel rotates thereby driving shaft rotates drive, because engagement in driving wheel and the follower, the rotation drive follower of driving wheel rotates; Driving wheel is gone into material web between driving wheel and the follower, material has the gap of driving wheel and follower to continue motion respectively through the swing link place, when driving wheel and follower forward pump housing outlet port to, engagement in driving wheel and the follower, thus material is extruded from the outlet port.In chuck of the present utility model, put into freezing mixture or heating agent, can keep temperature for the material of the certain specified temp of needs.

Because the utility model also is equipped with rack sleeve, rack sleeve plays the effect of sealing, in order to avoid the material in the pump housing leaks.Rear portion at support also is equipped with bearing housing, convenient for maintaining and replacing sealing.

Embodiment:

As shown in Figure 1: bitumenpump, it comprises driving shaft 1, bearing housing 2, support 3, the pump housing 4, driving wheel 5, follower 6, swing link 7, pump head 8, driven shaft 9 and chuck 16; Bearing housing 2 is installed in the rear portion of support 3, and the front end of support 3 is connected with the pump housing 4; Pump head 8 is installed in the front end of the pump housing 4; Driving wheel 5, follower 6, swing link 7 and driven shaft 9 are installed in the pump housing 4; Driven shaft 9 is fixed on the pump head 8; Follower 6 is placed on the driven shaft 9; Driving shaft 1 runs through bearing housing 2, support 3 and the pump housing 4; Driving wheel 5 is placed in driving shaft 1 front end; Chuck 16 is opened on support 3, places freezing mixture or heating agent in the chuck 16, puts into freezing mixture or heating agent in the chuck 16, can keep temperature for the material of the certain specified temp of needs.

As shown in Figure 2, also have outlet 10 and import 11 on the pump housing 4; The radius of follower 6 is less than the radius of driving wheel 5; Follower 6 places driving wheel 5 inside, and driving wheel 5 meshes in outlet 10 places of the pump housing 4 with follower 6; The relative position of driving wheel 5 and follower 6 engagement places also is equipped with swing link 7 between driving wheel 5 and the follower 6.

This bitumenpump also comprises rack sleeve 12; Rack sleeve 12 is installed on the front end of support 3, is placed in driving shaft 1 outside; Present embodiment rack sleeve 12 material therefors are that 35 chrome molybdenums add Ni-based cobalt base alloy, be applicable to more wear-resisting, high temperature resistant, hardness, corrosion are required under the higher working condition.

This bitumenpump also comprises driven axle sleeve 13; Driven axle sleeve 13 is installed between driven shaft 9 and the follower 6; Driven axle sleeve 13 material therefors of present embodiment are that 35 chrome molybdenums add Ni-based cobalt base alloy, be applicable to more wear-resisting, high temperature resistant, hardness, corrosion are required under the higher working condition.
