Abstract

The utility model discloses a single-screw pump having a horizontal delivery function and applied for a reaction vessel, which is vertically installed. The single-screw pump comprises a pump seat, a bush provided with an inner cylinder, a screw and a screw driving part. A discharge opening of the bush is equipped above a screw sealing zone. The single-screw pump is characterized in that a screw segment between the upper edge of the bush discharge opening and the upper end part of the screw sealing zone has no screw groove and no screw ridge; the screw segment is a boss with radial outer projections; and the gap between the outer edge of the boss and the inner cylinder ranges from 0.1 millimeter and 3 millimeters. Compared with the prior art, the single-screw pump provided in the utility model has the beneficial effects that a high-viscosity medium will not form a vortex and be pumped out from the discharge opening when conveyed to the discharge opening of the bush; instead, the high-viscosity medium will be stably horizontally delivered from the discharge opening of the bush; no blind angle where the high-viscosity medium will remain is present on the discharge opening of the bush; the high-viscosity medium has a stable pressure; and the high-viscosity medium leaked from the gap between the inner cylinder and the screw to the screw sealing zone is reduced to the minimum.

Description

A kind of have level and send the reaction kettle of function outside and use helical rotor pump

Technical field

The utility model relates to helical rotor pump, particularly relates to a kind ofly having level and sending the reaction kettle of function outside and use helical rotor pump.

Background technique

Reaction kettle belongs to the rotator type displacement pump of vertical installation with helical rotor pump; Comprise pump seat, be provided with lining, screw rod and the driver part thereof of inner core; Said driver part comprises motor and speed reducer thereof, coupling, and the connected body and the bearing support that connect said screw rod and said coupling.When said screw rod is driven when planet gyration is made at the machine barrel center by driver part; Volume near the working room of the lining material feeding mouth of reaction kettle neck increases the formation malleation gradually; High viscosity medium is inhaled under the effect of pressure reduction; Along with being rotated further of screw rod, cross-sectional area constantly reduces, and then high viscosity medium is pushed the lining discharge port.

Owing to receive the screw rod seal area left-hand thread medium-high viscosity medium pressure from bottom to top of below; High viscosity medium pumps from discharge port after the discharge port place forms eddy current; A small amount of high viscosity medium can be from the clearance leakage between machine barrel and the screw rod to seal area, and can there be the dead angle of being detained high viscosity medium in the eddy current of formation all the time at the discharge port place; Not only directly influence the stationarity of discharging, the high viscosity medium pressure stability is also poor.

Summary of the invention

The utility model technical problem to be solved is the defective that remedies above-mentioned existing technology, provides a kind of and has level and send the reaction kettle of function outside and use helical rotor pump.

The technical problem of the utility model solves through following technological scheme.

This have level and send the reaction kettle of function outside and use helical rotor pump, and vertical installation comprises pump seat, is provided with lining, the screw rod of inner core, and the bolt rod driving parts, and said lining discharge port is arranged on the top of said screw rod seal area.

This have reaction kettle that level sends function outside and with the characteristics of helical rotor pump be:

One section screw rod of the upper end portion of said lining discharge port upper edge and said screw rod seal area does not have screw channel and spiral shell rib; Be one the radially round platform of outer lug to be arranged; Gap between said round platform outer and the said inner core is 0.1～3.0mm; Because screw rod seal area left-hand thread medium-high viscosity medium pressure is from bottom to top cut down by said round platform; High viscosity medium pushes to and pumps from the lining discharge port after the discharge port place can not form eddy current, but sends outside from lining discharge port level reposefully, also can not have the dead angle of being detained high viscosity medium at lining discharge port place; The high viscosity medium pressure stability also is reduced to minute quantity from the clearance leakage between said inner core and the said screw rod to the high viscosity medium of said screw rod seal area.

The technical problem of the utility model solves through following further technological scheme.

Said round platform is that the upper-end surface is little and round platform that the lower end surface is big and upper-end surface are big and a kind of in the round platform that the lower end surface is little.

Said round platform is a round platform that single radially outer lug arranged and at least 2 radially a kind of in the range upon range of round platform of outer lug are arranged.

The overlapped way of said range upon range of round platform is that the upper-end surface is little and round platform that the lower end surface is big stacks gradually, the upper-end surface is big and the little round platform in lower end surface stacks gradually, and the upper-end surface is little and a kind of greatly and in the little round platform intersecting in lower end surface of round platform that the lower end surface is big and upper-end surface.

The radially outer lug quantity of the height of said round platform and said range upon range of round platform is by the special parameter decision of said screw rod parameter and suitable high viscosity medium.

Preferably, said round platform is connected with the spiral shell rib of said lining discharge port upper edge, can high viscosity medium directly be imported the lining discharge port through this part that is connected, and high viscosity medium is sent outside from lining discharge port level more reposefully.

The technical problem of the utility model solves through following further again technological scheme.

Said lining is to have double-deck machine barrel, also comprises the overcoat with heating and cooling structure, said outer be arranged with oil inlet pipe and oil outlet tube.

Said screw rod is arranged in the said inner core cavity, by said driver part driven rotary.

The spiral groove depth of said screw rod is by shoaling deeply gradually, and forms between the said inner core by big to little gradual change tangent plane.

Said bolt rod driving parts comprise drive motor and speed reducer thereof, coupling, and the connected body and the bearing support that connect said screw rod and said coupling.

Said coupling is a kind of in movable coupling of rigidity and the permanent coupling.

The movable coupling of said rigidity is a kind of in Hooks coupling universal coupling, cross groove coupling and the tooth embedding coupling.

The utility model beneficial effect compared with prior art is:

One section screw rod of the upper end portion of said lining discharge port upper edge and said screw rod seal area does not have screw channel and spiral shell rib; Be one the radially round platform of outer lug to be arranged; Gap between its outer and the inner core is 0.1～3.0mm; High viscosity medium pushes to and pumps from discharge port after lining discharge port place can not form eddy current, but sends outside from lining discharge port level reposefully, also can not have the dead angle of being detained high viscosity medium at lining discharge port place; The high viscosity medium pressure stability also is reduced to minute quantity from the high viscosity medium of the clearance leakage between inner core and the screw rod to screw rod seal area.
