Detailed Description
Referring to fig. 1, the utility model relates to a mechanical type well head automatic reagent feeding mechanism of sucker rod pump oil well's concrete structure is:
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 utility model provides a 1 bottoms of medicine storage tank can be provided with filter screen 3 that is used for filtering impurity in the medicine to prevent that some impurity in medicine storage tank 1 from influencing the operation of dosing pump 5, catheter 4 links as an organic wholely with filter screen 3, and catheter 4 is fixed in medicine storage tank 1 central authorities, and catheter 4 inlet is directly connected in the liquid medicine of filter screen 3 below, and catheter 4 liquid outlet links to each other with hose 11.
