Abstract

The invention relates to a rotary nozzle for defrosting and cleaning a rapid freezer. The head, which is provided with a perpendicular surface, of a nozzle body is changed to be threaded, so that a jet body is mounted on the nozzle body from the threaded part; and a nut is placed to achieve limiting and fixing effects. When a jet hole is blocked, cleaned or cleared, only the jet body is removed from the nozzle body; such treatment measure is convenient, and connection between the nozzle and a device is not damaged; and the connection and sealing conditions are not needed to be considered repeatedly.

Description

Swivel nozzle

Technical field

The present invention relates to a kind of freezing plant for quick freezing food, more particularly to one kind is formed for savings red leaves Frosting part, can not only simply remove red leaves, and possess defrosting and the cleaning nozzle of the freezing plant of durability.

Background technology

At present, such nozzle, is overall bolt connection on the pipeline at source of the gas or water source, and its shortcoming is：Work as spray-hole Blocking, nozzle need cleaning or arrange maintenance when, need by whole nozzle assembly in the lump from device dismantle, make nozzle with dress The threaded connection put is because frequently dismantling and installing and rapid wear, and connection when being difficult to ensure that subsequent installation is sealed.

The content of the invention

The invention aims to overcome the shortcomings of the above, there is provided a kind of to improve work efficiency, rotated using rational Nozzle.

The purpose of the present invention is achieved through the following technical solutions：A kind of swivel nozzle, removes for a kind of quick freezing machine Frost and cleaning, nozzle includes nozzle body, by order to rotate can which using instrument in the middle part of nozzle body, with least one pair of Parallel the first vertical, annular is formed at above-mentioned middle part and stop convex, and have the of the external diameter less than the diameter at above-mentioned middle part One cylinder body and the second cylinder body are constituted, and are provided with the first spiral shell on the outer peripheral face top of the second cylinder body Stricture of vagina, and between the first cylinder body and the second cylinder body, circumferentially it is provided with multiple insertion nozzle bodies First spray-hole of cylindrical wall sunk area, and be provided with for connecting supply compressed air in the inner peripheral surface bottom of nozzle body Distribution pipe the second screw thread；Rotation spray beam, the rotation spray beam is by cylinder side wall, in the upper and lower side one of above-mentioned side wall Arrange and the upper plate of the through hole for being inserted into nozzle body and lower plate composition, and the circumferentially side on upper plate are provided with centre To the second spray-hole for being provided with multiple obliquely insertions, and the rotation spray beam of annular is inserted by the top of nozzle body And it is convex to abut against the stop at middle part；Nut, the nut have annular, and in its outer peripheral face in order to revolve can which using instrument Turn, with least one pair of the second parallel vertical, inner peripheral surface is provided with screw thread for being screwed with the first screw thread, and at which Above-mentioned second cylinder body upper end is provided with spacing, so as to limit the bolted depth of nut and the first screw thread, so that on State in the state of rotation spray beam injects said nozzle body and can also rotate freely, the pressure flowed into by the lower end of nozzle body Contracting air or, the pressure reservoir space that temporal persistence is constituted in the sunk area by the first cylinder body and rotation spray beam Afterwards, then by the second spray-hole it is ejected into outside.

Further improvement of the present invention is：Nozzle body after the second screw thread is connected with device, rotation spray beam from First end of thread of nozzle body is loaded on body, by being screwed for nut and the first screw thread.

Further improvement of the present invention is：It is located at above-mentioned middle part and forms annular and stops convex, and the lower plate of rotation spray beam Between contact surface be the annular with 2-5mm or so width, and above-mentioned rotation spray beam upper plate and lower plate incline 5 °- 10°。

Further improvement of the present invention is：Circumferentially it is provided with the upper plate of rotation spray beam and multiple obliquely passes through The second logical spray-hole has various patterns：Through type, closing in type, flared type.

The present invention has advantages below compared with prior art：

When hole plug is sprayed, when cleaning or cleaning, it is only necessary to ejectisome is disassembled from nozzle body, it is not necessary to will spray Mouth is overall to be dismantled from device, so processes convenient, does not destroy the connection of nozzle and device, should not repeatedly consider the sealing for connecting Situation.
