The existing continuous dosing device of the electric pump can operate only by applying current, and certain resource loss exists. And some simple devices which freely drop the medicines by gravity are difficult to meet the flexible application of the oilfield field.
Disclosure of Invention
The invention aims to solve the technical problem of providing a mechanical wellhead automatic dosing device for a sucker rod pump oil well so as to overcome the defects in the prior art.
The technical scheme of the invention is as follows: the utility model provides a mechanical type well head automatic reagent feeding device of sucker-rod pump oil well which characterized in that: comprises a medicine storage tank and a medicine feeding pump, wherein the medicine storage tank is connected with the medicine feeding pump through a hose; wherein, the medicine storage tank comprises a tank body, a liquid guide pipe connected with a hose is arranged in the tank body, and a liquid discharge faucet is arranged at the lower part of the tank body; the dosing pump comprises a barrel, a plunger is arranged in the barrel, a spring is arranged below the plunger, a plunger handle is arranged above the plunger, a hose is communicated with the barrel through a first check valve which only feeds liquid but does not discharge liquid in the dosing pump, and a second check valve which only discharges liquid but does not discharge liquid is communicated below the barrel.
The bottom of the medicine storage tank is provided with a filter screen, the liquid guide pipe is connected with the filter screen into a whole, the liquid guide pipe is fixed in the center of the medicine storage tank, the liquid inlet of the liquid guide pipe is directly communicated with the liquid medicine below the filter screen, and the liquid outlet of the liquid guide pipe is connected with the hose.
The medicine storage tank is provided with a liquid level meter.
And a liquid level meter box is arranged outside the liquid level meter.
The medicine storage tank and the medicine feeding pump are made of metal, the liquid guide pipe is made of hard resin materials, the hose is made of a polymer material with an anti-corrosion function, and the liquid level meter box is made of metal.
The inner walls of the medicine storage tank and the medicine adding pump are sprayed with anticorrosive paint.
The invention has the technical effects that:
the medicine feeding pump realizes liquid suction and liquid discharge through the up-and-down movement of the plunger, and particularly, the mechanical medicine feeding pump body is provided with two check valves, wherein the first check valve only feeds liquid but does not discharge liquid, and the second check valve only discharges liquid but does not discharge liquid. When the dosing pump collides a plunger handle by virtue of a ram fixed on a polished rod in the process of up-and-down movement of the sucker rod, the plunger moves downwards, the first check valve is closed under the action of internal pressure, the second check valve is opened under the action of internal pressure, medicines in the dosing pump are discharged from the second check valve, and a spring in the dosing pump is compressed at the same time; when the sucker rod moves upwards, the spring realizes elastic recovery to enable the plunger to move upwards, negative pressure is formed in the dosing pump, the second check valve is closed under the action of self gravity and negative pressure, the first check valve is opened, medicines in the medicine storage tank are sucked into the dosing pump through the check valve, then the sucker rod moves downwards again to continue to discharge liquid, and therefore reciprocating liquid discharge, liquid suction and liquid discharge are achieved.

Detailed Description
Referring to fig. 1, the mechanical wellhead automatic chemical feeding device for the sucker-rod pumping well, which is disclosed by the invention, has the specific structure that:
comprises a medicine storage tank 1 and a medicine feeding pump 5, wherein the medicine storage tank 1 is connected with the medicine feeding pump 5 through a hose 11; wherein,
the medicine storage tank 1 comprises a tank body, a liquid guide pipe 4 connected with a hose 11 is arranged in the tank body, and a liquid discharge tap 13 for replacing medicines and discharging liquid when the medicine storage tank 1 is cleaned is arranged at the lower part of the tank body;
the dosing pump 5 comprises a barrel, a plunger 6 is arranged in the barrel, a spring 9 is arranged below the plunger 6, a plunger handle 10 is arranged above the plunger 6, a hose 11 is communicated with the barrel through a first check valve 7 which only feeds liquid but does not discharge liquid in the dosing pump 5, and a second check valve 8 which only discharges liquid but does not discharge liquid is communicated below the barrel.
The bottom of the medicine storage tank 1 can be provided with a filter screen 3 for filtering impurities in medicines so as to prevent the impurities in the medicine storage tank 1 from influencing the operation of the medicine feeding pump 5, the liquid guide pipe 4 and the filter screen 3 are connected into a whole, the liquid guide pipe 4 is fixed at the center of the medicine storage tank 1, the liquid inlet of the liquid guide pipe 4 is directly communicated with the liquid medicine below the filter screen 3, and the liquid outlet of the liquid guide pipe 4 is connected with the hose 11.
The medicine storage tank 1 of the present invention may be provided with a liquid level gauge 14 to facilitate display of the height of the liquid level in the medicine storage tank 1.
The liquid level meter 14 of the present invention may be provided with a liquid level meter box 2. Since the apparatus is installed in the field, in order to prevent it from being damaged, the gauge 14 may be protected by a metal gauge box 2, which only the person concerned can open for viewing.
The medicine storage tank 1 and the medicine feeding pump 5 in the invention can be made of metal, the liquid guide pipe 4 can be made of hard resin material, the hose 11 can be made of polymer material with an anti-corrosion function, and the liquid level meter box 2 can be made of metal liquid level meter box.
The inner walls of the medicine storage tank 1 and the medicine adding pump 5 can be sprayed with anticorrosive paint to prevent the medicine storage tank from being corroded.
In the process of up-and-down movement of the suspension point of the pumping unit, the power of a motor required in the down stroke is far less than that of the motor in the up stroke, and part of the power of the motor does not play a role. Therefore, a part of the redundant work is transferred to the mechanical dosing pump, so that the dosing pump 5 runs by means of the redundant work in the down stroke of the pumping unit, and the continuous dosing of the medicines in the shaft of the sucker rod pumping well is realized. An annular liquid outlet (made of resin materials, high elastic plasticity and corrosion resistance) is designed according to an actual wellhead and is fixed near the second check valve 8, so that the medicine can flow into the bottom along the outer wall of the oil pipe, the medicine is produced from the oil pipe after being mixed with well liquid at the bottom, and internal and external corrosion prevention of the oil pipe and internal corrosion prevention of a lower sleeve are realized. In addition, the dosing speed of the dosing pump 5 can be adjusted by the length of the plunger handle 10.
The components and structures of the present embodiments that are not described in detail are well known in the art and do not constitute essential structural elements or elements.
