Abstract
The utility model discloses a single-bearing screw rod pump for pumping solid particles. The single-bearing screw rod pump comprises a pump shell, a rotor and a transmission shaft, wherein the pump shell is provided with a feeding opening, a discharging opening and a shaft hole; the rotor is arranged in the pump shell; one end of the rotor is located in the discharging opening and the other end of the rotor is connected with the transmission shaft; the transmission shaft stretches out from the shaft hole of the pump shell; the shaft hole is provided with a bearing seat and a bearing; and the transmission shaft is sleeved with the bearing. According to the single-bearing screw rod pump, one end of the rotor is located in the discharging opening and a manner of fixing two ends of a traditional screw rod pump rotor is changed; the shaft hole is provided with the bearing seat and the bearing and the transmission shaft is sleeved with the bearing; with the adoption of the structure, only one bearing is used and a spiral with a trapezoidal section is arranged on the rotor; and the spiral is used for discharging the solid particles out from the discharging opening so that the direct pumping of the solid particles is realized. Compared with the prior art, the structure is simple and reasonable and the efficiency of pumping the solid particles is high.
Description
[technical field]
The utility model relates to screw pump technical field, particularly a kind of single-bearing screw pump of pumping solid particle.
[background technique]
Screw pump is to rely on the spatial volume that engages that the pump housing forms with screw rod change and move and carry liquid, the screw pump of existing market is only applicable to medium and is generally liquid, emulsion etc., for the pumping of solid granule, need extra equipment that solid particle is mixed with to solution or suspension, and then carry with screw pump, thereby its technique is comparatively complicated, working efficiency is lower with respect to direct pumping solid particle, because this class screw pump is for pumping liquid, seal arrangement and bearing means for its inside also have higher requirement, generally in two ends of rotor, bearing and seal ring are all set, therefore this screw rod that can only carry liquid also has complex structure, the not shortcoming of easy care.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of single-bearing screw pump of pumping solid particle, can realize direct pumping solid particle, increases work efficiency, and simplifies mechanical structure, improves reasonable structure.
For achieving the above object, the utility model proposes a kind of single-bearing screw pump of pumping solid particle, comprise pump case, rotor and transmission shaft, on described pump case, offer material entrance, discharge port and axis hole, rotor is arranged in pump case, and one end of described rotor is arranged in discharge port, the other end of rotor is connected with transmission shaft, described transmission shaft stretches out from the axis hole of pump case, is provided with bearing support and bearing on axis hole, and described bearing housing is contained on transmission shaft.
As preferably, on described rotor, be provided with spiral, described spiral is made up of multiple grooves, and the cross section of groove is trapezoidal, for the solid particle for the treatment of pumping provides circulation passage.
As preferably, on described transmission shaft, be provided with step, described bearing is fixed on step, makes bearing fixing convenient and firm.
As preferably, on described axis hole, be provided with bearing cap, protection internal bearings, prevents that foreign matter from entering.
The beneficial effects of the utility model: one end of the utility model rotor is arranged in discharge port, change the fixing mode in traditional screw pump rotor two ends, the bearing support arranging on axis hole and bearing, bearing housing is contained on transmission shaft, such structure, the utility model only uses a bearing, be trapezoidal spiral by cross section is set on rotor, spiral exits solid particle from pump chamber from discharge port, realize the direct pumping of solid particle, compared with prior art, structure is more simple and reasonable, and pumping solid material efficiency is higher.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
