Description
Technical field
The utility model relates to the plunger type grouting pump in the engineering construction equipment, is specially a kind of high-consistency cream stock pump pump head structure of carrying various fluid foods, particularly high viscosity transformation power lotion material that is applicable to.
Background technique
At present; In engineering construction and in industrial fields such as oil, chemical industry, mining, normally be suitable for the plunger type stock pump and carry out the conveying of fluid and slurry, still; This plunger pump can in the following slurry fashion of pumping medium-viscosity; When carrying the body of paste material, its suction performance is poor, efficient is low even can not suction pump send etc., and shortcoming has just displayed, and causes this application can only use screw pump; But existing market use screw pump exist again pumping pressure (＜5MPa) little, can not adapt to the shortcoming of engine request.
The model utility content
The technical problem that the utility model solved is to provide a kind of high-consistency cream stock pump pump head structure, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technological scheme to realize:
A kind of high-consistency cream stock pump pump head structure mainly comprises hopper assembly, stirring feeding mechanism, binder drum and pump structure, wherein; The stirring feeding mechanism is positioned at the hopper neutral position of hopper assembly; Be that a band advances helix structure, its parts feeder structure end crosses the hopper assembly, and extends to " L " type pipe valve in the binder drum of its underpart; Simultaneously, binder drum rear portion also is connected with pumping mechanism; Said binder drum is a cavity structure, and its front portion is provided with a cream slurry discharge port, and binder drum inside is equipped with " L " type pipe valve, and " L " type pipe valve front end parcel stirs feeding mechanism and extends to the end portion in the binder drum; Said pumping mechanism has adopted horizontal single action biserial hydraulic piston pump, and its main body comprises two piston hydraulic cylinders, end that is connected to " L " type pipe valve in two piston hydraulic cylinders, and another is connected in the cavity of binder drum.
In the pump head structure; Two pumping cylinders link to each other through two structure annular distances opening behind the binder drum with pump head; And through " O " type seal ring and pumping cylinder end seal; Two structure hole front portions are to have with concave arc sealing surface and " L " type pipe valve convex arc type sealing surface sealed attachment, and through distributing mechanism " L " type pipe valve are changed between two pumping cylinders.
There is one to be used for controlling the distributing mechanism that two piston hydraulic cylinder states of pumping mechanism switch in binder drum set inside, is used for control " L " type pipe valve and between two pumping cylinders, connects and separate switching.During work, the pumping cylinder that connects with " L " type pipe valve begins to form negative pressure and suction when the piston rollback, and the cream slurry in the hopper is got in the pumping cylinder by " L " type pipe valve; Simultaneously, push away before another pumping cylinder piston that material is pushed in the binder drum, and under pressure through the discharge port output of binder drum, when suck all arrive end points with pumping after, " L " type pipe valve switches to the another one pumping cylinder distributing under the oil cylinder effect.So perseveration is accomplished the pumping of cream slurry.
In the utility model, the spiral pusher of said stirring feeding mechanism is driven by speed-adjustable motor, and in order to the rotating speed of control charging pusher, it preferably adopts stepless speed-change motor or oil hydraulic motor.
In the utility model, also mixing blade can be set on the stirring feeding mechanism in the hopper assembly, can not solidify in order to guarantee the cream slurry in hopper, to keep stirring action.
The described pump head of the utility model has the function of active push charging; When charging, can drive the charging pusher and assist the charging of lotion material through external motor or oil hydraulic motor; And can control inlet amount and feed rate through regulating motor speed; Simultaneously, also available utilization regulate motor speed adapt to pumping different viscosities and fluidity lotion or slurry, with suitable different construction requirement.
Beneficial effect: the utility model pump rate is adjustable, reliable in action, noise is low and working service is convenient, and is widely applicable simultaneously, can be at the various different fluid of pumping under the pressure-changed condition (semifluid, slurry, lotion etc.) material.
Description of drawings
Fig. 1 is the schematic representation of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with specific embodiment, further set forth the utility model.
Schematic representation referring to the preferred embodiment of a kind of high-consistency cream stock pump pump head structure of Fig. 1 in the present embodiment, stirs the below that feeding mechanism 4 is positioned at hopper assembly 2; For comprising screw propulsion rod and mixing blade; Relevant action is carried out through connecting speed-adjustable motor 1 in its top, and the rear portion of stirring feeding mechanism 4 links to each other with " L " type pipe valve 6, simultaneously; " L " type pipe valve 6 rear portions are connected to one of them piston hydraulic cylinder front end of pump structure 7; The front end of another piston hydraulic cylinder of pump structure 7 then is connected to binder drum 3 rear ends, and binder drum 3 front ends are provided with a cream slurry discharge port, and also is provided with a distributing mechanism 5 in the bottom of binder drum 3.
In the present embodiment, by external AC380V electrical source of power power is provided, controls external driven by motor hydraulic pump works, the pressure oil that is produced by oil hydraulic pump again drives pump structure 7 actions, and the piston that drives at last in two piston hydraulic cylinders produces alternate reciprocating motion.Drive by speed-adjustable motor 1 simultaneously and stir feeding mechanism 4 runnings, after pump in stock is stirred, carry to drop in " L " type pipe valve 6 of bottom.Because the orderly action between " L " type pipe valve 6 and the pump structure 7 makes the cream slurry constantly be inhaled into pump structure 7 and deliver to the job site through the cream slurry discharge port of binder drum 3 from hopper.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
