Description

Technical Field

[0001] This utility model belongs to the technical field of jet components, specifically relating to a negative pressure jet component for a plasma powder making device. Background Technology

[0002] Plasma powder making equipment is used to achieve high sphericity, nano-sizing, and multi-element alloying of refractory metals. The raw materials are heated by high temperature plasma, which can rapidly heat and melt irregularly shaped powder particles. Therefore, when internal heating is required during processing, it is usually achieved by spraying flames through a spraying component. The existing spraying component is a device installed on the plasma powder making equipment for spraying flame heating. When the exhaust air generates a flame inside, a negative pressure is created to enter the powder for operation.

[0003] When existing jetting assemblies are installed on plasma pulverizing equipment, the connecting pipe is secured to the plasma generator by a mounting clip. This makes reinforcement difficult after installation, and the exposed plasma generator and jetting head are susceptible to damage from contact. Furthermore, the introduction of high-pressure argon gas and external forces can cause loosening or even detachment, leading to reduced jetting efficiency and compromising the ease of securing the top of the jetting assembly on the plasma pulverizing equipment. Therefore, this invention proposes a negative pressure jetting assembly for plasma pulverizing equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a negative pressure jet assembly for a plasma powder making device, in order to solve the problems mentioned in the background art, such as the connection pipe being locked onto the plasma generator by a mounting clip, which makes it inconvenient to reinforce the installation after installation, and the plasma generator and jet head being exposed to the outside world after installation, making them prone to contact damage, and the easy loosening or even falling off when high-pressure argon gas is introduced into the interior to generate pressure or when subjected to external force, thereby reducing the jetting effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure jetting component for a plasma powder making device, comprising a jetting reactor, a jetting head fixed at the top of the jetting reactor, a plasma generator disposed at the top of the jetting head, an installation clip engaged at the top of the plasma generator, a connecting pipe disposed at the top of the installation clip, a protective and reinforcing mechanism disposed at the top of the jetting reactor on the outer surface of the plasma generator, and a reinforced protective mechanism disposed at the bottom of the jetting head inside the jetting reactor;

[0006] The protective reinforcement mechanism includes a protective component located on the top of the jet reactor on the outer surface of the plasma generator. An elastic connecting component is provided at the top edge of the protective component. A clamping engagement component is provided at the connection between the top of the elastic connecting component and the upper surface of the mounting clip. A rotary clamping component is provided at the bottom of the elastic connecting component at the edge of the protective component.

[0007] The enhanced protection mechanism includes a reinforced protection component located at the bottom of the nozzle on the inner surface of the jet reactor.

[0008] Preferably, the inside of the jet reactor has a water circulation cooling structure, a pipe opening is provided at the top of one side of the jet reactor, and a mounting plate is provided at the bottom of the jet reactor.

[0009] Preferably, the protective assembly includes an outer protective cover that is fixedly mounted on the top of the jet reactor on the outer surface of the plasma generator by screws, and the edge of the outer protective cover has a groove formed thereon.

[0010] Preferably, the elastic connection assembly includes an internal threaded groove formed at the inner edge of the jet reactor, the inner surface edge of the internal threaded groove integrally forming a limiting groove at equal intervals, a connecting rod sliding inside the limiting groove, a compression spring fitted onto the outer surface of the connecting rod inside the limiting groove, and a sliding plate extending from the bottom end of the connecting rod into the inner threaded groove for limiting.

[0011] Preferably, the clamping and engaging assembly includes a clamping plate mounted on the top of the connecting rod via a bearing, wherein a clamping hole is provided at the top edge of the mounting head, and the end of the clamping plate is engaged and connected with the interior of the clamping hole.

[0012] Preferably, the rotary clamping assembly includes an internally threaded ring rotatably mounted on the top of the outer protective cover via an internally threaded groove, and the lower surface of the internally threaded ring presses against the surface of the sliding plate.

[0013] Preferably, the enhanced protection component includes a thickened plate integrally disposed at the bottom end of the nozzle on the inner surface of the injection reactor, a top ventilated protective cover integrally disposed on the inner surface of the thickened plate, a fixed mounting ring integrally disposed at the top of the top ventilated protective cover, and the bottom end of the nozzle matches the internal structure of the fixed mounting ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a protective and reinforcing mechanism, an outer protective cover can be fixedly installed on the top of the plasma generator. The outer protective cover and the partition groove isolate and protect the top of the plasma generator, making it less susceptible to contact and exposure to external heat, thus preventing potential hazards. At the same time, the end of the clamping plate is elastically and tightly pressed into the inside of the clamping hole. The internal thread groove further reinforces the mounting clip by pressing the sliding plate and the clamping plate together. The mounting clip is less likely to loosen or fall off when subjected to argon gas and external forces. The precise entry of argon gas allows the jet head to fully spray flames, improving the protection, installation, and fixation of the jet assembly on the plasma powder making equipment for the top of the plasma generator and the mounting clip.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a negative pressure jet assembly for a plasma powder making device, including a jet reactor 101, a jet head 104 fixed at the top of the jet reactor 101, a plasma generator 105 at the top of the jet head 104, an installation clip 106 snapped onto the top of the plasma generator 105, a connecting pipe 107 at the top of the installation clip 106, a water circulation cooling structure 102 formed inside the jet reactor 101, a pipe opening 103 at the top of one side of the jet reactor 101, an installation plate 108 at the bottom of the jet reactor 101, a protective and reinforcing mechanism at the top of the jet reactor 101 on the outer surface of the plasma generator 105, and a reinforced protection mechanism at the bottom of the jet head 104 inside the jet reactor 101.

[0025] The protective and reinforcing mechanism includes a protective component located at the top of the jet reactor 101 on the outer surface of the plasma generator 105. An elastic connecting component is provided at the top edge of the protective component. A clamping and engaging component is provided at the connection between the top of the elastic connecting component and the upper surface of the mounting clip 106. A rotating clamping component is provided at the bottom of the elastic connecting component at the edge of the protective component. When the jet assembly is installed and in use, the protective and reinforcing mechanism can safely protect the top of the plasma generator 105 and reinforce the mounting clip 106, making it less prone to loosening and instability.

[0026] In order to facilitate the protection of the top of the plasma generator 105 by means of a protective component, in this embodiment, preferably, the protective component includes an outer protective cover 1051 fixedly installed on the top of the jet reactor 101 on the outer surface of the plasma generator 105 by screws. A groove 1055 is formed at the edge of the outer protective cover 1051, so that the outer protective cover 1051 can be fixedly installed on the top of the jet reactor 101 on the outer surface of the plasma generator 105 for protection, and is safely protected by the groove 1055 and the outer protective cover 1051, and is not easily damaged by heat or contact.

[0027] To facilitate the elastic connection and engagement of the clamping plate 1054 via the elastic connection assembly, in this embodiment, preferably, the elastic connection assembly includes an internal threaded groove 1057 formed at the inner edge of the jet reactor 101. The inner surface edge of the internal threaded groove 1057 is integrally formed with a limiting groove 1050 at equal intervals. A connecting rod 1053 slides inside the limiting groove 1050. A compression spring 1058 is fitted inside the limiting groove 1050 on the outer surface of the connecting rod 1053. The bottom end of the connecting rod 1053 extends into the internal threaded groove 1057 and is limited by a sliding plate 1059. The compression spring 1058 can deform to drive the sliding plate 1059 and the connecting rod 1053 to slide and press tightly together inside the limiting groove 1050, thereby causing the clamping plate 1054 to be elastically and tightly engaged.

[0028] In order to facilitate the clamping and tightening of the mounting clip 106 after installation, in this embodiment, preferably, the clamping and tightening assembly includes a clip plate 1054 mounted on the top of the connecting rod 1053 by a bearing. A clip hole 1056 is provided at the top edge of the mounting clip 106, and the end of the clip plate 1054 is engaged with the inside of the clip hole 1056. When the clip plate 1054 is deformed and tightened, the end of the clip plate 1054 is engaged with the inside of the clip hole 1056 for reinforcement and installation.

[0029] In order to facilitate the re-tightening and locking of the connecting rod 1053 and the clamping plate 1054 after elastic pressing by the rotary clamping assembly, in this embodiment, preferably, the rotary clamping assembly includes an internally threaded ring 1052 rotatably mounted on the top of the outer protective cover 1051 through an internally threaded groove 1057, and the lower surface of the internally threaded ring 1052 presses against the surface of the slide plate 1059. The internally threaded ring 1052 can be rotated on the inner surface of the internally threaded groove 1057 to move down and press against the surface of the slide plate 1059, which facilitates the reinforcement installation after the connecting rod 1053 and the clamping plate 1054 are tightly pressed and installed.

[0030] The enhanced protection mechanism includes a reinforced protection component located at the bottom of the nozzle 104 on the inner surface of the injection reactor 101. When the nozzle 104 emits flames after installation, the reinforced protection mechanism will strengthen the protection of the inner surface of the injection reactor 101, making it less likely to deform or be damaged when exposed to high temperatures.

[0031] To enhance the protection of the inner surface of the jet reactor 101 and prevent it from being damaged by prolonged high temperatures, in this embodiment, the enhanced protection component preferably includes a thickened plate 1042 integrally disposed at the bottom of the jet head 104 on the inner surface of the jet reactor 101. A top ventilated protective cover 1041 is integrally disposed on the inner surface of the thickened plate 1042, and a fixing ring 1043 is integrally disposed at the top of the top ventilated protective cover 1041. The bottom of the jet head 104 matches the internal structure of the fixing ring 1043. The top ventilated protective cover 1041 can be installed at the end of the jet head 104 through the fixing ring 1043, and the thickened plate 1042 strengthens the protection by bringing the top ventilated protective cover 1041 into contact with the inner surface of the jet reactor 101, making it less prone to damage when exposed to heat for a long time.

[0032] The jet reactor 101 in this utility model is prior art, disclosed in a high-temperature plasma powder making process in the authorized patent application number CN117205836A, and will not be described in detail here.

[0033] The working principle and usage process of this utility model: When using the negative pressure jet component of this plasma powder making equipment, the mounting plate 108 first contacts the installation position on the cooling chamber of the plasma powder making equipment and is fixed by bolts. After the fixed installation, the mounting clip 106 is inserted and installed on the top of the plasma generator 105. The connecting pipe 107 is connected to the external argon gas booster and pressurized to enter the powder-mixed argon gas. Then, the vacuum inside the jet head 104 is evacuated by the external vacuum equipment. Therefore, the powder-mixed argon gas is introduced into the jet reactor 101 and the air is vented out.

[0034] At this time, the plasma generator 105 forms a high-temperature plasma flame during operation. The nozzle 104 connected to the nozzle 103 forms a negative pressure in the injection reactor 101 and draws the argon gas of the mixed raw material into the injection reactor 101. The raw material enters the injection reactor 101 and melts and spheroidizes. The argon gas of the mixed powder is cooled by the water circulation cooling structure 102 and recycled.

[0035] Then, when the flame is ejected from the end of the nozzle 104 after installation, it directly contacts the inside of the top ventilated protective cover 1041 to protect it. At the same time, the outside of the top ventilated protective cover 1041 is reinforced by a thickened plate 1042, so that the ejected flame does not directly contact the inner surface of the jet reactor 101. This makes it less likely for the surface of the jet reactor 101 to be damaged by long-term direct contact with the flame, effectively strengthening protection, extending service life, and improving the protection effect of the jet assembly on the inner surface of the jet reactor 101 when it is installed on the plasma pulverizing equipment for jet treatment.

[0036] Finally, before using the jet assembly after installation, an outer protective cover 1051 is fixed again to the outer surface of the plasma generator 105 at the top of the jet reactor 101 for protection. Simultaneously, the heat is isolated by the partition 1055, ensuring safety and preventing damage or danger from external contact. While providing protection, the connecting rod 1053 and the clamping plate 1054 are pulled, and the angle of the clamping plate 1054 is adjusted so that its end aligns with the clamping hole 1056. The clamping plate 1054 is then released, and the deformation of the compression spring 1058 elastically connects the connecting rod 1053 and the clamping plate 1054 until the end of the clamping plate 1054 is engaged. The internal elastic compression of the clasp 1056 allows the internal threaded ring 1052 to rotate within the internal threaded groove 1057, rotating it until its bottom end contacts the surface of the sliding plate 1059 and presses it firmly. This secures the clasp 1054 and the mounting clasp 106 together. During use, the mounting clasp 106 is less likely to loosen or fall off when subjected to argon gas or external force. The precise entry of argon gas allows the jet head 104 to fully spray flame, improving the protection and fixation of the jet assembly on the top of the plasma generator 105 and the mounting clasp 106 in the plasma powder making equipment.

[0037] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
