Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, specifically a mixed jet cleaning nozzle. Background Technology
[0002] The cleaning nozzle is a key component in cleaning equipment used to spray cleaning media. Its core function is to transform the cleaning media into a jet with a certain pressure, flow rate and spray pattern through a specific structure, so as to achieve cleaning operations on the surface of workpieces, equipment or specific areas.
[0003] Currently, most cleaning nozzles can only use a single medium to clean the surface of the workpiece. This requires workers to use different cleaning media for different types of contaminants on the workpiece surface. As a result, cleaning nozzles using a single medium are less effective at cleaning different contaminants and often require multiple cleanings, which is time-consuming and labor-intensive. Utility Model Content
[0004] The purpose of this invention is to provide a mixed jet cleaning nozzle to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixed jet cleaning nozzle, comprising: a nozzle; a suction chamber, fitted inside the nozzle; a throat, penetrating and fitted inside the nozzle, the throat being connected to the interior of the suction chamber, the connection between the throat and the suction chamber being tapered to increase the pressure of gas or liquid after passing through the throat; a nozzle, fixedly mounted at one end of the nozzle, the nozzle output end extending into the interior of the suction chamber, the nozzle output end being tapered; and an air inlet pipe, fixedly mounted on the nozzle, the interior of the air inlet pipe being connected to the interior of the suction chamber.
[0006] Preferably, it further includes: a connector head, threaded onto the nozzle inlet end; an annular cone, fixedly disposed at the nozzle inlet end; and a sealing sleeve, threaded onto the surface of the connector head, wherein the sealing sleeve is configured to move axially along the connector head and eventually fit tightly against the surface of the annular cone when rotated, so as to provide a secondary seal at the connection between the connector head and the nozzle.
[0007] Preferably, it further includes: a threaded sleeve fixedly disposed at one end of the nozzle; and a threaded platform fixedly disposed on the surface of the nozzle, wherein the outer surface of the threaded platform is threaded to the inner surface of the threaded sleeve.
[0008] Preferably, it further includes: a first sealing gasket disposed inside the threaded sleeve, the surface of the first sealing gasket being in close contact with the threaded platform and the nozzle surface; and a second sealing gasket fitted onto the surface of the annular cone, the second sealing gasket being in close contact with the nozzle and the sealing sleeve surface.
[0009] Preferably, it further includes: a plurality of protrusions fixedly disposed on the surface of the connector head, wherein the cross-section of the protrusions is trapezoidal.
[0010] Preferably, it further includes: a diffusion groove, which is formed at the output end of the nozzle, the diffusion groove being conical in shape, and the diffusion groove being connected to the inside of the throat.
[0011] This invention provides a mixed jet cleaning nozzle, which has the following beneficial effects:
[0012] (1) This utility model connects the nozzle to the suction chamber inside the nozzle, so that air and high-pressure water can be gathered in the suction chamber at the same time and mixed thoroughly. The mixed gas and liquid are then pressurized and sprayed onto the surface of the workpiece through the throat tube, so that the high-speed jet sprayed after the gas and liquid mixture has both the kinetic energy of the liquid and the expansion potential energy of the gas, forming a "gas-liquid mixed jet", which can effectively remove stubborn stains, oxide scale, oil stains, etc., and improve the cleaning effect. Furthermore, it can clean workpieces with different needs through gas-liquid alternating cleaning, high and low pressure water cleaning and single medium cleaning, thus improving the practicality of the nozzle.
[0013] (2) This utility model rotates the sealing sleeve to move along the surface of the pipe head, and finally fits tightly against the surface of the annular cone. This allows the pipe head to be tightened and fixed at the same time as the nozzle is threadedly connected, preventing the threads from loosening and improving the connection strength between the pipe head and the nozzle. At the same time, the tight fit between the sealing sleeve and the annular cone and the fit of the second sealing gasket improve the sealing performance of the connection. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] This utility model provides a technical solution: Referring to 1-3, in this embodiment, a mixed jet cleaning nozzle includes: a nozzle 1; a suction chamber 5, which is fitted inside the nozzle 1; a throat 3, which is fitted through the nozzle 1 and connected to the inside of the suction chamber 5, with the connection between the throat 3 and the suction chamber 5 being conical, so that the pressure of the gas or liquid increases after passing through the throat 3; a nozzle 2, which is fixedly installed at one end of the nozzle 1, with the output end of the nozzle 2 extending into the inside of the suction chamber 5, and the output end of the nozzle 2 being conical; and an air inlet pipe 6, which is fixedly installed on the nozzle 1, with the inside of the air inlet pipe 6 connected to the inside of the suction chamber 5. The suction chamber 5 allows gas and liquid to converge inside, forming a bubble-liquid mixture. The throat 3 pressurizes the gas-liquid mixture, increasing the impact force on the workpiece.
[0020] It also includes: a connector 10, threaded onto the input end of the nozzle 2; an annular cone 11, fixedly mounted on the input end of the nozzle 2; and a sealing sleeve 12, threaded onto the surface of the connector 10. The sealing sleeve 12 is configured to move axially along the connector 10 and eventually fit tightly against the surface of the annular cone 11 when rotated, so as to perform secondary sealing at the connection between the connector 10 and the nozzle 2. By rotating the sealing sleeve 12, the sealing sleeve 12 moves along the surface of the connector 10 and eventually fits tightly against the surface of the annular cone 11, so that the connector 10 is subjected to secondary compression and fixation 1 while being threadedly connected to the nozzle 2, which improves the connection strength between the connector 10 and the nozzle 2. At the same time, the tight fit between the sealing sleeve 12 and the annular cone 11 and the fit of the second sealing gasket 13 improve the sealing performance at the connection.
[0021] It also includes: a threaded sleeve 8 fixedly installed at one end of the nozzle 1; and a threaded platform 7 fixedly installed on the surface of the nozzle 2, with the outer surface of the threaded platform 7 threaded to the inner surface of the threaded sleeve 8, which facilitates the disassembly and installation of the nozzle 2 and facilitates the cleaning of the interior of the suction chamber 5.
[0022] It also includes: a first sealing gasket 9, which is disposed inside the threaded sleeve 8, and the surface of the first sealing gasket 9 is in close contact with the surface of the threaded platform 7 and the nozzle 1; and a second sealing gasket 13, which is sleeved on the surface of the annular cone 11, and the second sealing gasket 13 is in close contact with the surface of the nozzle 2 and the sealing sleeve 12 to improve the sealing performance.
[0023] It also includes: several protrusions 14, which are fixedly installed on the surface of the connector 10. The cross-section of the protrusions 14 is trapezoidal, which improves the connection strength and sealing between the pipeline and the connector 10.
[0024] It also includes: a diffuser 4, which is located at the output end of the nozzle 1. The diffuser 4 is cone-shaped and is connected to the inside of the throat 3 to improve the spray range.
[0025] This invention provides a mixed jet cleaning nozzle, the specific working principle of which is as follows:
[0026] High-pressure water and gas are introduced into nozzle 2 and nozzle 1 respectively, so that air and high-pressure water can converge in suction chamber 5 for thorough mixing. The mixed gas and liquid are then pressurized through throat tube 3 and diffused in diffuser 4 before being sprayed onto the surface of workpiece. This results in a high-speed jet that combines the kinetic energy of liquid with the expansion potential energy of gas, forming a "gas-liquid mixed jet" that effectively removes stubborn stains, oxide scale, oil stains, etc.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
