Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a plurality" means two or more unless specifically limited otherwise.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to specific situations.

As shown in fig. 1 to 4, the present invention provides a 360 ° inner nozzle, comprising: the outer shell 1, the lining 2, the inner core 3, the arc head 4 and the baffle 5, wherein the outer shell 1 is a barrel-shaped shell, the liner 2 is embedded in the outer shell 1, the inner core 3 is arranged in the liner 2 through a support arm 6, specifically, for better support of the core 3, there are at least two support arms 6, and these support arms 6 are arranged circumferentially uniformly, while, for stability of the support, these supporting arms 6 may be arranged in a single layer or multiple layers along the extension direction of the liner 2, and a flow passage is formed between the inner wall of the liner 2 and the inner core 3, the arc head 4 is approximately in a solid horn shape, one end of the arc head 4 with smaller diameter is connected with the inner core 3, the other end is provided with the baffle 5, the diameter of the blocking piece 5 is larger than the maximum diameter of the arc head 4, and the blocking piece 5 and part of the arc head 4 are exposed out of the outer shell 1. The baffle 5 is used for realizing the large-angle and high-strength reverse-angle injection, and the abrasion is low. When the nozzle is used, the jet medium enters the nozzle and then enters the supporting section of the inner core along the inner core with the taper, the supporting section is narrow and the number of the sections is small, the influence on the radial uniform distribution of the jet medium is low, then the jet medium can be converged, the jet medium is uniformly distributed under the action of air pressure to enter the arc head, one part flies out from the opening forwards, and the other part is reflected by the separation blade and ejected backwards at the reverse angle.

The improved structure is characterized in that the arc head 4 and the blocking piece 5 are sleeved on a screw rod 7, one end of the screw rod 7 is connected with the inner core 3, and the other end of the screw rod 7 is connected with a screw cap 8. All the parts are connected through the screw 7, so that the arc head 4 and the baffle 5 can be quickly detached and replaced according to actual use requirements.

In a further improvement, the other end of the inner core 3, which is opposite to the arc head 4, is conical. The tapered end of the inner core 3 reduces the flow resistance of the flowing medium in the nozzle while reducing wear on the end of the inner core 3.

The further improvement is that a butt joint ring 9 is sleeved on the screw 7 between the inner core 3 and the arc head 4. Different processing products, the spout opening range requirement of nozzle is different, and the suitable nozzle of whole change then need be to conventional nozzle, and the nozzle that this embodiment provided, through the tie ring of changing different length, just can realize the size of spout department circular arc head and inside lining interval, has realized the adjustment of spout opening range promptly.

In a further improvement, a protective head 10 is sleeved on the nut end of the screw 7 and the nut 8. The protective head is arranged to protect the screw cap, so that the situation that the screw cap is deformed by spraying or is mixed with foreign matters, and the screw cap is inconvenient to disassemble is avoided.

The further improvement is that the lining 2 comprises a base section 21, a support section 22 and an outlet section 23 which are arranged in sequence, and the support section 22 is provided with a support arm 6 connected with the inner core 3.

The further improvement is that an arc-shaped surface 24 is arranged on the inner wall of the arc head end of the lining 2. Through the cooperation of arcwall face and arc head to make the flow direction of spraying the medium can lead, simultaneously, reduced separation blade wearing and tearing.

In a further improvement, the thickness of the edge of the baffle 5 is gradually reduced outwards.

The nozzle can realize various adjustment modes according to requirements:

the opening amplitude of the nozzle can be adjusted by the length of the butt joint ring;

the injection angle is realized by changing the shape of the arc head;

the reverse angle injection angle is realized by adjusting the shape of the arc head and the shape of the baffle plate;

the reverse angle injection amount is realized by adjusting the shape of the arc head and the diameters of the baffle plate and the shell.

The 360-degree inner nozzle provided by the invention can ensure that sprayed pills, abrasives or coatings and the like can be uniformly distributed in the radial direction at 360 degrees; the assembly design is simple, the disassembly and the replacement of a wearing part are easy, when the part is worn, only the wearing part needs to be replaced, and the whole part does not need to be replaced; the opening amplitude of the nozzle is simple to adjust, and only the length of the connecting ring is required to be adjusted; the front end is provided with the baffle plate, so that the large-angle and high-strength reverse angle injection can be realized, the abrasion is very low, and if the reverse angle injection angle and the injection amount are controlled, the large-angle and high-strength reverse angle injection can be realized by adjusting the arc of the arc head, the baffle plate and the diameter of the outer shell.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention.
