In order to realize the purpose, the utility model provides a technical scheme is:
a filter cylinder structure of a deep-layer separate-pumping and mixed-discharging oil-well pump comprises a cylinder body, wherein two symmetrical slotted holes are formed in the lower portion of the cylinder body, a multi-hole arc-shaped plate concentric with the cylinder body is hermetically installed in each slotted hole, an arc-shaped groove concentric with the cylinder body is formed in the upper end of each slotted hole, an arc-shaped raised line is fixed at the upper end of each multi-hole arc-shaped plate, an inner ring is fixed in the cylinder body, the upper portion of each inner ring corresponds to the corresponding slotted hole, a rubber sleeve is fixed on the outer edge of the upper portion of each inner ring and is in sealing contact with the inner edge of the lower portion of each multi-hole arc-shaped plate, a lantern ring is sleeved on the cylinder body, the lower portion of each multi-hole arc-shaped plate is located in the lantern ring, an arc-shaped base plate corresponding to the slotted hole is fixed on.
Specifically, the arc-shaped backing plate is concentric with the cylinder body.
Specifically, rubber strips are fixed at the upper end and the front end and the rear end of the porous arc plate and are in sealing contact with the hole wall of the slotted hole.
Specifically, the convex strip is concentric with the cylinder body.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses, simple structure, porous arc is low for porous section of thick bamboo working costs, consequently can reduce cost of maintenance, only needs to change porous arc during the maintenance, intensity of labour when having reduced the workman maintenance, can reduce the required time of maintenance simultaneously.
