Description

Single-screw pump screw structure convenient to overhaul Technical Field The utility model relates to the technical field of single-screw pumps, in particular to a screw structure of a single-screw pump, which is convenient to overhaul. Background The single screw pump is a rotor pump working based on the rotary meshing positive displacement principle, the core structure of the single screw pump consists of an eccentric screw and a fixed bushing, and a closed cavity is formed by the mutual meshing of the eccentric screw and the fixed bushing, so that the stable conveying of media is realized. In the use of the single-screw pump, the traditional connection mode between the single-screw pump connecting pipe and the feeding body and the discharging body often depends on a bolt structure, and when the internal screw structure of the single-screw pump needs to be overhauled, the whole pump body often needs to be disassembled, so that the operation is complex, the time and the labor are wasted, the downtime of equipment is increased, and the production efficiency is reduced. Therefore, to the above-mentioned inconvenient problem of realizing stable connection and easy access, can design a single-screw pump screw structure convenient to access, when single-screw pump in the in-process of using, when needs are overhauld, only need dismantle corresponding module, need not whole dismantlement, simplified the maintenance process greatly, in conclusion, this single-screw pump screw structure has realized the stability of connection and the characteristics convenient to access through accurate design and ingenious locking mechanism, has improved the reliability and the maintenance efficiency of equipment greatly. Disclosure of utility model In order to overcome single screw pump in the in-process of using, the bolted connection mode appears becoming flexible easily when long-time operation or receiving great pressure, leads to the material to leak, in addition, frequent dismantlement still probably causes the damage to the pump body, has increased maintenance cost, and what need to improve, and then inconvenient realization is stable to be connected and the problem of easy access. The technical scheme includes that the screw rod structure of the single-screw pump convenient to overhaul comprises a bearing seat, a feeding body, connecting pipes, connecting plates, mounting plates, inserting rods, inserting holes, guide brackets, locking rods, locking elbows, locking rings, locking springs, built-in grooves and ratchet toothed plates, wherein the feeding body is arranged at the front end of the bearing seat, the connecting pipes are arranged at the front end of the feeding body, two groups of connecting plates are fixedly arranged at two ends of the connecting pipes, the mounting plates are fixedly arranged at the front end of the feeding body, two groups of inserting rods are fixedly arranged on the inner walls of the upper side and the lower side of the rear end connecting plates, two groups of inserting holes are fixedly arranged on the upper side and the lower side of the mounting plates, two groups of guide brackets are fixedly arranged on the outer walls of the upper side and the lower side of the mounting plates, the locking rods are fixedly arranged at the lower ends of the locking rods, the locking springs are fixedly arranged at the upper ends of the locking rings, the built-in grooves are formed in the inner sides of the inserting rods, and the ratchet toothed plates are fixedly arranged in the inner sides of the built-in grooves. Preferably, when the single screw pump is in the in-process of using, at first, carry out closely laminating with the front end mounting panel of feed body with the rear end connecting plate of connecting pipe, realize preliminary connection, in this in-process, the spliced pole of both sides inner wall about the rear end connecting plate inserts the spliced pole of both sides inner wall about the mounting panel respectively inside, ensure the stability and the accuracy of connection, at this moment, under locking spring's elastic action, then can drive the locking elbow of locking pole lower extreme and slide to lower group's tooth groove inner wall along the tooth cambered surface of ratchet pinion rack, and closely contradict with tooth groove inner wall, cause connecting plate and mounting panel to realize locking state, thereby can accomplish the rear end installation work of connecting pipe, when overhauling screw structure, then can drive the locking elbow of locking pole lower extreme and break away from the tooth groove inner wall of ratchet rack board, cause rear end connecting plate and mounting panel to realize the unblock state, after this step is accomplished, and then carry out quick overhaul to inside screw structure, like this, when need to dismantle corresponding module, whole dismantlement is greatly simplified, the high-speed screw pump has been accomplished, the h
