Abstract
A centrifugal starch separator rotating drum spray nozzle is composed of a spray nozzle base, a spray nozzle body, a spray nozzle core, a spray nozzle body seal ring and a spray nozzle base seal ring. The spray nozzle base is matched with and installed on the wall of a separator rotating drum through a conical surface. The side face of the spray nozzle base is connected and provided with the spray nozzle body through threads. The spray nozzle core with a spray hole is placed in the center hole of the spray nozzle body. The seal rings are arranged between the spray nozzle base and the separator rotating drum and between the spray nozzle body and the spray nozzle base respectively. The centrifugal starch separator rotating drum spray nozzle has the advantages that rotating drum spray nozzle parts are firm and reliable in installation, detachment and assembly are convenient, sealing performance is good, and influences of a spray nozzle base installation hole on the strength of a rotating drum are small; a turning bend is arranged in a spray hole runner in the spray nozzle, and therefore material blockage does not easily occur, the direction of the spray hole can be easily ensured during installation, and running stability of a separator can be improved.
Description
Technical field
The invention belongs to centrifugation machinery technical field, be specifically related to a kind of centrifugal starch separator rotary drum nozzle.
Background technology
Centrifugal starch separator is for the separation of starch milk seitan, fiber finer slag, protein and other insolubility material, a kind of widely used centrifugation machinery, its critical piece is that an inside is with the rotary drum of taper video disc group, seperator when work rotary drum High Rotation Speed, utilizes acting on of centrifugal force in clearance between two dishes, to realize solid-liquid feed separation.In rotary drum outer rim, be uniformly distributed several nozzles, spray orifice UNICOM rotary drum on nozzle is inner, when drum rotating, solid sprays at a high speed from the spray orifice of nozzle with pulpous state form under the effect of centrifugal force, and the structure of nozzle and spray orifice size have a great impact the service behaviour of centrifugal starch separator.
In order to guarantee separating effect, the spray orifice direction of seperator nozzle should be along the tangential direction of rotary drum outer rim.The centrifugal starch separator rotary drum nozzle of prior art, normally nozzle is directly tilted to be arranged on rotary drum with screw thread, once screwed hole damage can cause rotary drum integral body to be scrapped, and the screwed hole that need to tangentially process on rotary drum, complex structure, the material of excision is many, also larger on drum strength impact; Another kind of structural formula is at nozzle head processing inclined, nozzle is radially installed along rotary drum, as the rotary drum nozzle arrangements proposing in Chinese utility model patent description CN201375930Y, the shortcoming of this structure is that spray orifice on the corner easily stops up, the rotation when incline direction of spray orifice can be installed with nozzle on each nozzle simultaneously changes, specification requirement to installation and maintenance is higher, easily, because the incline direction of spray orifice is inconsistent, causes disk centrifuge unstable working condition.
Summary of the invention
Shortcoming for existing in centrifugal starch separator rotary drum nozzle prior art, the utility model proposes a kind of combined type rotary drum nozzle arrangements, nozzle carrier, nozzle body, nozzle core, nozzle body sealing ring and nozzle carrier sealing ring, consists of.Nozzle carrier is conical, top seal, and pit is arranged at bottom, is placed in the conical bore of offering on disk centrifuge rotatory drum wall easy installation and removal; The small end of nozzle carrier is towards rotary drum outside, and during work, under the effect of centrifugal force, nozzle carrier meeting automatic impaction faying face, is not easy to occur nozzle obscission.Nozzle carrier side is processed with a screwed hole, communicates with the groove of its bottom.Nozzle body is cylindrical, and screw thread is arranged at bottom, screws in the screwed hole of nozzle carrier, and there is a centre bore with the level nozzle body inside, and nozzle core is placed in the step place in centre bore, and there is a spray orifice axially connecting at nozzle core center.By changing nozzle core, can obtain the spray orifice of different sizes, adapt to the separation requirement of different material; On the other hand, nozzle core can adopt more wear-resisting high hardness material to make, and after spray orifice wearing and tearing, only need to change nozzle core, can save the operating cost of seperator.
There is an annular boss nozzle body outside, and nozzle body sealing ring is placed between nozzle carrier and boss, in the process of nozzle body screw-in screwed hole, sealing ring is compressed; In addition, on the nozzle carrier outer circle conical surface, have annular seal groove one, place nozzle carrier sealing ring in groove, the effect of two sealing rings is leaked liquids in rotary drum while preventing seperator work.
The utility model is compared with the centrifugal starch separator rotary drum nozzle of prior art, and the nozzle installing hole on separator drum is conical bore radially, little on drum strength impact, and nozzle mounting or dismounting are convenient, and connection reliability is high, good airproof performance.Nozzle body adopts screw thread to be arranged in the screwed hole of nozzle carrier side, spray orifice is along the axis of nozzle body, the impact of the anglec of rotation while not installed by nozzle body, easily guarantee correct direction and the uniformity of each spray orifice, spray orifice runner is turnover not, be not easy to occur feed blocking, thereby guaranteed the stability of seperator running.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and the present invention is further described.
Accompanying drawing 1 is the structure chart of the embodiment of the present invention.
Piece mark in Fig. 1: 1-nozzle body, 2-nozzle core, 3-nozzle body sealing ring, 4-nozzle carrier, 5-nozzle carrier sealing ring, 6-separator drum.
The specific embodiment
Below in conjunction with accompanying drawing, 1 embodiment is described in detail technical solutions of the utility model.
Nozzle carrier 4 is arranged on separator drum 6 by the cooperation of a taper hole and the conical surface; the top of nozzle carrier 4 is sealed; pit is arranged at bottom; the O-ring seals that nozzle carrier sealing ring 5 is elastomeric material; be placed in the annular seal groove on the nozzle carrier 4 outer circle conical surfaces; play the effect of sealants; because the installation taper hole small end of nozzle carrier 4 is towards separator drum 6 outsides; so the centrifugal force that during work, separator drum 6 rotations produce can make nozzle carrier 4 be fixed on reliably on separator drum 6, under stopped status, the dismounting of nozzle carrier 4 is also very convenient.
The side of nozzle carrier 4 is processed with a screwed hole, communicates with the pit of its bottom.External screw thread is arranged at nozzle body 1 bottom, screw in the screwed hole of nozzle carrier 4, there is counterbore the end of nozzle carrier 4 side screwed holes, there is an annular boss nozzle body 1 outside, nozzle body sealing ring 3 is also the O-ring seals of elastomeric material, be placed between counterbore and boss, when nozzle body 1 screws in the screwed hole on nozzle carrier 4, sealing ring compressed, between two parts, play sealing function.There is a centre bore with the level nozzle body 1 inside, and nozzle core 2 is placed in centre bore, and is located by step, has a spray orifice axially connecting at nozzle core 2 centers, and nozzle core 2 is made by Hardmetal materials, to improve the wearability of spray orifice.
