Abstract

The utility model relates to a medicine filling device mechanically driven, which solves the problems that the existing medicine filling device is difficult to take power source and medicinal liquid has low availability ratio. The utility model is characterized in that a carriage (1) is provided with a power taking device (2), a mechanical pump (4) and a medicine storage pot (6) with a liquid level meter (5), wherein a gear box (3) is connected with the mechanical pump (4) through the power taking device (2), and the mechanical pump (4) is connected with the medicine storage pot (6) and a medicine injecting gun (9) through a liquid inflow pipe (7) and a liquid outflow pipe (8). The medicine filling device uses vehicle-carrying air-pressure force as the power source, and has the characteristics of convenient medicine filling and high availability ratio of medicinal liquid.

Description

The Mechanical Driven chemicals dosing plant

Technical field:

The utility model relates to used chemicals dosing plant on the well head of oil field development field, particularly Mechanical Driven chemicals dosing plant.

Background technology:

In the oil recovery process of oil field, be easy to produce wax deposition owing to pump for a long time in the well, scale formation, in order to prevent wax deposition on the tubing wall, fouling, often adopt on the oil field from the production wellhead clear wax control chemical agent of between oil pipe and casing annulus, annotating, present adding method thereof has two kinds, a kind of is the drop dosing, there is not the additionaling power source, the gravity that can only lean on soup is automatically toward the interior dosing of well, it adds dose and determines by the unlatching size of Artificial Control valve, the dose size can not accurately be measured, the dosing pipeline is easy to generate and freezes stifled phenomenon, and the soup of adding is faintly acid more, generally adopts stainless steel device, be easy to take place to steal lose phenomenon, device is big with the opposed task difficulty of well head simultaneously; Another kind is to adopt a large amount of medicament of disposable adding, and it is by injection pump medicine to be injected into well, and wax removal scale removal effect is had discontinuity, and labor strength is big, and the medicament utilization rate is low, the cost height.

The utility model content:

In order to overcome the existing deficiency that chemicals dosing plant power source difficulty is got and the soup utilization rate is low, the utility model provides a kind of Mechanical Driven chemicals dosing plant, and this device is that power source has the convenient and high characteristics of soup utilization rate of dosing with vehicle-mounted atmospheric pressure.

The technical solution of the utility model is: a kind of Mechanical Driven chemicals dosing plant comprises railway carriage and gearbox, be equipped with power takeoff, mechanical pump on the railway carriage and have the medicine storing pot of content gauge, gearbox links to each other with mechanical pump by power takeoff, and mechanical pump links to each other with medicine storing pot and injection rifle by feed tube and drain pipe.

The beneficial effect that the utlity model has is: this chemicals dosing plant is to be equipped with power takeoff on railway carriage, mechanical pump and have the medicine storing pot of content gauge, gearbox links to each other with mechanical pump by power takeoff, have clutch on the power takeoff, the power output shaft that makes gearbox by clutch and power takeoff in conjunction with or separate, the adding of control soup, mechanical pump links to each other with medicine storing pot and injection rifle by feed tube and drain pipe, mechanical pump sucks the soup in the medicine storing pot by feed tube, from mechanical pump, discharge soup in the injection rifle by drain pipe, thereby inject into well by the injection rifle, make soup reach certain pressure by mechanical pump, be convenient to soup successfully liquid feeding in well, improve the utilization rate of dosing quality and soup, saved administration timing of drug, reduced working strength of workers.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is vertical views of Fig. 1.

1-railway carriage among the figure, 2-power takeoff, 3-gearbox, 4-mechanical pump, 5-content gauge, 6-medicine storing pot, 7-feed tube, 8-drain pipe, 9-injection rifle.

The specific embodiment:

Below in conjunction with accompanying drawing will the utility model is described in further detail:

By Fig. 1 in conjunction with shown in Figure 2, a kind of Mechanical Driven chemicals dosing plant comprises railway carriage 1 and gearbox 3, be equipped with power takeoff 2 on the railway carriage 1, mechanical pump 4 and have the medicine storing pot 6 of content gauge 5, have clutch on the power takeoff 2, the power output shaft that makes gearbox 3 by clutch and power takeoff 2 in conjunction with or separate, content gauge 5 can show the drug storage amount in the medicine storing pot 6, power takeoff 2 links to each other with mechanical pump 4, mechanical pump 4 links to each other with medicine storing pot 6 and injection rifle 9 by feed tube 7 and drain pipe 8, when being meshed with the power output shaft of gearbox 3 under the control of power takeoff 2 at clutch, mechanical pump 4 sucks the soup in the medicine storing pot 6 by feed tube 7, by drain pipe 8 soup is injected in the medicine rifle 9 from mechanical pump 4, the soup that injection rifle 9 will have pressure injects into well.

Owing to use this chemicals dosing plant, can solve the remote continuous dosing problem in oil field flexiblely, the power taking from the motor vehicle of this dosing method, make soup reach certain pressure by mechanical pump, be convenient to soup successfully liquid feeding in well, improve the utilization rate of dosing quality and soup, saved administration timing of drug, reduced working strength of workers.

Claims

1, a kind of Mechanical Driven chemicals dosing plant, comprise railway carriage (1) and gearbox (3), it is characterized in that: be equipped with power takeoff (2), mechanical pump (4) on the railway carriage (1) and have the medicine storing pot (6) of content gauge (5), gearbox (3) links to each other with mechanical pump (4) by power takeoff (2), and mechanical pump (4) links to each other with medicine storing pot (6) and injection rifle (9) by feed tube (7) and drain pipe (8).
