Description

Technical Field

[0001] The utility model relates to the field of water atomization copper powder making, in particular to a water atomization spray plate. Background Art

[0002] Copper powder manufacturing includes three methods: electrolysis, water mist injection and gas injection. Among them, water mist injection powder making has the lowest cost. At the same time, due to its low cost, there are also problems such as uneven copper powder particles and poor roundness.

[0003] However, during the water mist spraying process, due to the presence of a small amount of impurities in the water quality, the nozzle position will be blocked for a long time, which will affect the overall water output. Therefore, it is necessary to carry out targeted optimization of the nozzles on the spray disc, and to simultaneously clean up the hidden dangers caused by the blockage during long-term operation.

[0004] Therefore, we propose a water atomization spray disc to solve the above problems. Utility Model Content

The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A water atomization spray disc comprises a mounting ring, two gear rings are slidably connected inside the mounting ring, a connecting ring is slidably connected to the top of the gear ring, a cavity area is opened inside the gear ring, a limiting ring is slidably connected inside the cavity area, a spray head is installed on the outer wall of the gear ring, a spring piece is installed inside the cavity area, and a cleaning plug rod is connected to the center of the spring piece.

[0008] In a further embodiment, the two gear rings are distributed in an upper and lower superposition manner, and the two gear rings partially overlap each other.

[0009] In a further embodiment, the connection ring and the cavity area together form a sealing structure, and the outer wall of the connection ring is connected to a water inlet pipe.

[0010] In a further embodiment, the width of the limiting ring is smallest near the center of the mounting ring, the width of the limiting ring is largest away from the center of the mounting ring, and the limiting ring is fixedly connected to the connecting ring.

[0011] In a further embodiment, the cleaning rod and the water outlet of the nozzle are coaxially distributed, and the nozzle and the interior of the cavity area are interconnected.

[0012] In a further embodiment, the nozzles are distributed on the inner ring of the gear ring, and the nozzles are connected to the gear ring via bearings.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The present application adopts two nozzles forming an annular structure that overlap each other to spray the molten metal liquid. The overlapping area of ​​the two gear rings is the main area of ​​spraying and is also the position where the molten metal liquid falls. The other areas can be cleaned inside the nozzle under the action of the limit ring, spring piece and cleaning rod to avoid blockage inside the nozzle, effectively prevent impurities in the water from clogging the nozzle for years and causing the problem of normal water spraying, thereby reducing the maintenance cost of users. Secondly, the two gear rings are distributed in an annular shape, and the overlapping area of ​​the two annular distributions forms a shape similar to a complete circle. The two gear rings also have a height difference, which further widens the spray angle and spray range, and allows the metal liquid to be sprayed in all directions downward to the maximum extent, thereby improving the overall production yield.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figure 1-5 In an embodiment of the utility model, a water atomization spray disc comprises a mounting ring 1, two gear rings 2 are slidably connected inside the mounting ring 1, a connecting ring 3 is slidably connected to the top of the gear ring 2, a cavity area 5 is opened inside the gear ring 2, a limiting ring 6 is slidably connected inside the cavity area 5, a nozzle 7 is installed on the outer wall of the gear ring 2, a spring piece 8 is installed inside the cavity area 5, a cleaning plug rod 9 is connected to the center of the spring piece 8, the two gear rings 2 are distributed in an upper and lower superimposed manner, the two gear rings 2 partially overlap each other, and the overlapping area of ​​the two gear rings 2 pours liquid metal from the center downward, and the nozzles 7 around take turns to spray water on the metal liquid.

[0025] Example 2: Please refer to Figure 1-5, which is different from Example 1 in that: the connecting ring 3 and the cavity area 5 together form a sealing structure, the outer wall of the connecting ring 3 is connected to a water inlet pipe, and the cavity area 5 is mainly used for the flow of coolant and transports coolant to each nozzle 7.

[0026] The cleaning rod 9 and the water outlet of the nozzle 7 are coaxially distributed, and the nozzle 7 is connected to the inside of the cavity area 5. The cleaning rod 9 can be inserted to clean the inside of the nozzle 7 to avoid blockage inside the nozzle 7.

[0027] The nozzles 7 are distributed on the inner ring of the gear ring 2, and the nozzles 7 and the gear ring 2 are connected by bearings. Since the spacing between the two gear rings 2 is too close, in order to reduce the collision between the nozzles 7 and other gear rings 2, they are connected as bearings, which causes damage to the nozzles 7.

[0028] Example 3: Please refer to Figure 1-5 , which is different from Example 1 in that: the width of the limiting ring 6 is the smallest near the center of the mounting ring 1, and the width of the limiting ring 6 is the largest away from the center of the mounting ring 1. The limiting ring 6 is fixedly connected to the connecting ring 3. The limiting ring 6 is mainly used to control the depth of the cleaning plug 9 inserted into the nozzle 7. It is in a fully inserted state away from the center of the mounting ring 1 for cleaning dirt, and is in a non-inserted state near the center of the mounting ring 1 to facilitate water flow to spray out from the nozzle 7.

[0029] The working principle of the utility model is:

[0030] First, water is input through a water pipe to the bottom of the connecting ring 3, that is, the cavity area 5. Under the action of high-pressure water, water circulates inside the cavity area 5 and is finally sprayed outward from the nozzle 7. The water flow is mainly sprayed from the nozzle 7 on the side of the gear ring 2 close to the center of the mounting ring 1. At the same time, the driving motor at the shaft end of the driving tooth 4 is turned on to drive the driving tooth 4 to rotate. There are two driving teeth 4, which are distributed up and down, and each drives two gear rings 2 respectively.

[0031] The connecting ring 3 and the limiting ring 6 do not move with the rotation of the gear ring 2. When the nozzle 7, the cleaning plug rod 9 and the spring piece 8 gradually rotate to a position away from the center of the mounting circle 1, that is, the area with the largest width of the limiting ring 6, the limiting ring 6 with the largest width will squeeze the spring piece 8 and the cleaning plug rod 9, allowing the cleaning plug rod 9 to gradually insert into the interior of the nozzle 7 to discharge the dirt inside the nozzle 7 outwards. When the nozzle 7, the cleaning plug rod 9 and the spring piece 8 move to the thinnest area of ​​the limiting ring 6, they cannot be squeezed, and the cleaning plug rod 9 cannot penetrate into the interior of the nozzle 7. At this time, the water flow can flow out normally.

[0032] It should be added that the spring piece 8 should be designed as a thin and long sheet as much as possible to reduce the resistance of the water flow when it flows outward from the nozzle 7.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
