Description

Technical Field

[0001] This utility model belongs to the field of quartz recovery technology in high-pressure reactors, specifically relating to a quartz recovery nozzle for high-pressure reactors. Background Technology

[0002] Quartz crystals are an important industrial raw material. During the crystal cultivation process in an autoclave, a certain amount of quartz waste often remains at the bottom of the autoclave, with numerous impurities adhering to its surface. If this quartz waste at the bottom of the autoclave is mixed with new raw materials, it may crystallize or release impurities at high temperatures, affecting the crystallization quality of single-crystal quartz crystals. Simultaneously, to ensure high-quality recrystallization in the next cycle, the autoclave must be thoroughly cleaned after the previous crystallization cycle, primarily by removing the quartz waste remaining at the bottom. Therefore, recycling quartz waste from the autoclave is a necessary measure for resource recycling and process stability. In existing technologies, to facilitate the cleaning of quartz waste, the autoclave is often placed at a slight angle, with the bottom slightly higher than the top opening. A straight-through metal pipe is then inserted into the autoclave, and a high-pressure water jet is used to flush out the remaining quartz waste. However, this method is time-consuming, uses a large amount of water, is labor-intensive, and has high cleaning costs. Summary of the Invention

[0003] In view of the aforementioned shortcomings of existing methods for quartz recovery in high-pressure reactors, the purpose of this utility model is to propose a quartz recovery nozzle for high-pressure reactors.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows: a quartz recovery nozzle for an autoclave, comprising: a nozzle body, one end of which is provided with a water outlet and the other end with a high-pressure water pipe interface, a main channel connecting the high-pressure water pipe interface and the water outlet is provided inside the nozzle body, a first high-pressure nozzle is provided at the water outlet, and multiple nozzle groups are provided on the outer wall of the nozzle body located between the middle and the high-pressure water pipe interface, each nozzle group including multiple sub-high-pressure nozzles distributed in a circle, each sub-high-pressure nozzle being connected to the main channel through a corresponding branch channel, and the angle between the axis of each branch channel and the axis of the main channel being an acute angle, and the outer diameter of the nozzle body gradually decreasing from the middle to the water outlet.

[0005] The technical solution of this utility model has the following technical effects: (1) Apart from the first high-pressure nozzle set at the outlet of the nozzle body, the present invention sets multiple nozzle groups on the outer wall of the nozzle body located between the middle and the high-pressure water pipe interface. After the nozzle is connected to the high-pressure water pipe, the first high-pressure nozzle and several sub-high-pressure nozzles included in the multiple nozzle groups spray high-pressure water from multiple positions and angles to flush out the quartz waste at the bottom of the high-pressure reactor, greatly shortening the time and greatly reducing the water consumption. (2) The present invention designs the angle between the axis of each branch channel corresponding to the sub-high pressure nozzle and the axis of the main channel to be an acute angle. The reverse pressure generated by the jet of the sub-high pressure nozzle can also provide self-propulsion for the nozzle body to move forward to the bottom of the high pressure vessel. Compared with the existing hand-held straight metal pipe operation method, it can reduce labor intensity. (3) The outer diameter of the nozzle body gradually decreases from the middle to the outlet. The circular-to-conical shape enables the nozzle to enter the bottom of the autoclave more quickly and conveniently to flush out the quartz waste at the bottom of the autoclave.

[0006] In one embodiment, the outlet is coaxially arranged with the main channel.

[0007] Advantages: This design makes it easier for the nozzle to enter the bottom of the autoclave and for the quartz in front of the nozzle to be ejected from the bottom of the autoclave.

[0008] In one embodiment, the outer diameter of the nozzle body gradually decreases from the middle towards the high-pressure water pipe interface.

[0009] Advantages: This design allows the nozzle to be easily retrieved by staff after the quartz waste inside the vessel is flushed out.

[0010] In one embodiment, the nozzle group includes a first nozzle group and a second nozzle group distributed on different circumferences. The first nozzle group includes a plurality of first sub-high-pressure nozzles, and the second nozzle group includes a plurality of second sub-high-pressure nozzles. The first sub-high-pressure nozzles and the second sub-high-pressure nozzles are distributed in a cross pattern in the circumferential direction.

[0011] Advantages: This design allows for the installation of as many first and second high-pressure nozzles as possible, thus shortening the quartz recovery time.

[0012] In one embodiment, the first sub-high-pressure nozzle and the second sub-high-pressure nozzle have different water outlet angles.

[0013] Advantages: The first and second sub-high-pressure nozzles are distributed in a cross pattern, and the angle between the corresponding branch channels and the main channel is different, resulting in different rinsing directions for the quartz at the bottom of the autoclave. This design can maximize the cleaning of quartz at different locations at the bottom of the autoclave, thus improving cleaning efficiency.

[0014] In one embodiment, the orifice diameters of the first high-pressure nozzle and the sub-high-pressure nozzle are 2mm-4mm.

[0015] Advantages: Selecting the size of the first high-pressure nozzle and the sub-high-pressure nozzle within this range can minimize water consumption and shorten the time, while the small-hole jet will generate a correspondingly large impact force.

[0016] In one embodiment, an external thread structure adapted to the internal thread of the high-pressure water pipe connector is provided on the outer wall of the high-pressure water pipe interface to achieve a detachable connection between the nozzle body and the high-pressure water pipe connector.

[0017] Advantages: The threaded structure facilitates assembly and improves assembly efficiency.

[0018] In one embodiment, a boss is also provided on the outer wall of the high-pressure water pipe interface.

[0019] Advantages: The boss can be used to fasten and limit the rotation position of the high-pressure water pipe at the water pipe interface, which makes it easier for the operator to determine whether the high-pressure water pipe has been rotated into place; and the boss can also be used as a clamping part to facilitate the tightening of the high-pressure water pipe.

[0020] In one embodiment, both the first high-pressure nozzle and the sub-high-pressure nozzle are ceramic high-pressure nozzles.

[0021] Advantages: The use of ceramic high-pressure nozzles can provide anti-oxidation and corrosion resistance, significantly reducing maintenance costs.

[0022] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0024] In the diagram: Nozzle body - 1; Water outlet - 2; High-pressure water pipe interface - 3; Main channel - 4; First high-pressure nozzle - 5; Branch channel - 6; First sub-high-pressure nozzle - 7; Second sub-high-pressure nozzle - 8; Boss - 9. Detailed Implementation

[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1 , Figure 2This embodiment of a high-pressure autoclave quartz recovery nozzle includes a nozzle body 1, with a water outlet 2 at one end and a high-pressure water pipe interface 3 at the other end. The nozzle body has a main channel 4 connecting the high-pressure water pipe interface and the water outlet. A first high-pressure nozzle 5 is installed at the water outlet; in this embodiment, the first high-pressure nozzle is connected to the water outlet via a thread. Multiple nozzle groups are arranged on the outer wall of the nozzle body located between the middle and the high-pressure water pipe interface. Each nozzle group includes multiple sub-high-pressure nozzles distributed in a circle. Each sub-high-pressure nozzle is connected to the main channel through a corresponding branch channel 6, and the angle between the axis of each branch channel and the axis of the main channel is an acute angle. The high-pressure water jet from the sub-high-pressure nozzle flushes out the quartz waste inside the autoclave. Using the aforementioned nozzle structure to flush out the quartz waste in the autoclave can significantly shorten the time, reduce water consumption, and lower labor intensity. The outer diameter of the nozzle body gradually decreases from the middle to the outlet. The outer wall of the nozzle body between the middle and the outlet can be set as a smooth arc transition to make the outer diameter of the nozzle body gradually decrease. This design is more conducive to the rapid movement of the nozzle towards the bottom of the autoclave and the flushing out of the quartz inside the autoclave directly in front of the nozzle. Of course, the outer wall of the nozzle body between the middle and the outlet can also be a straight line transition to make the outer diameter of the nozzle body gradually decrease.

[0027] In this embodiment, the outlet and the main channel are coaxially arranged. The axes of the high-pressure water pipe interface, the main channel, the outlet and the first high-pressure nozzle are in a straight line. Combined with the reverse jet of high-pressure water sprayed by the sub-high-pressure nozzle, it is more conducive to the nozzle body moving to the bottom of the autoclave and flushing out the quartz waste at the bottom of the autoclave.

[0028] In this embodiment, the outer diameter of the nozzle body gradually decreases from the middle towards the high-pressure water pipe interface. This gradual decrease in outer diameter can be achieved using a straight line or a smooth, curved transition. Because the autoclave is tilted during recovery, this design allows for easier operation and use compared to the original straight-through metal pipe connection. Furthermore, after the nozzle body has cleaned the quartz waste from the autoclave, it makes it easier for workers to retract the high-pressure hose and nozzle.

[0029] In this embodiment, the nozzle group includes a first nozzle group and a second nozzle group distributed on different circumferences. The first nozzle group includes multiple first sub-high-pressure nozzles 7, and the second nozzle group includes multiple second sub-high-pressure nozzles 8. The first and second sub-high-pressure nozzles are distributed in a circumferentially intersecting manner. In this embodiment, the first nozzle group includes three first sub-high-pressure nozzles, and the second nozzle group includes three second sub-high-pressure nozzles. The first and second sub-high-pressure nozzles are distributed on different circumferences and are distributed in a circumferentially intersecting manner. This design allows for the maximum number of sub-high-pressure nozzles to be set. The high-pressure reverse water jet can provide the nozzle with a strong reverse thrust, which can easily move the nozzle to the bottom of the vessel and more efficiently clean the quartz waste in the vessel, saving cleaning time. Furthermore, the first and second sub-high-pressure nozzles are quickly assembled with the nozzle body via threads.

[0030] In this embodiment, the water outlet angles of the first and second sub-high-pressure nozzles are different. Specifically, the angle between the axis of each branch channel and the axis of the main channel is an acute angle. The angles formed by the axis of the branch channel corresponding to the first sub-high-pressure nozzle and the axis of the main channel, and the angles formed by the axis of the branch channel corresponding to the second sub-high-pressure nozzle and the axis of the main channel, are not equal, resulting in different water outlet angles for the first and second sub-high-pressure nozzles. The purpose of this is twofold: first, to provide thrust for the nozzle body to enter the autoclave and move to the bottom of the autoclave; second, the different jet angles of the high-pressure water ejected from the different sub-high-pressure nozzles relative to the axis of the main channel enable a wider range of cleaning of quartz waste inside the autoclave.

[0031] In this embodiment, the orifice diameters of the first high-pressure nozzle and the sub-high-pressure nozzle are 2mm-4mm. Specifically, through actual testing, when using the traditional method of directly inserting a straight-through metal pipe into the autoclave to recover quartz waste, a water pump of 12.5 cubic meters per hour is used, and a single autoclave takes about 30 minutes and uses about 6 cubic meters of water. Using the nozzles designed in this invention, with the outer diameters of both the first and sub-high-pressure nozzles being 2mm, a water pump of 12.5 cubic meters per hour is used, and a single autoclave takes about 15 minutes and uses about 3 cubic meters of water to flush out and recover all the quartz waste. With the outer diameters of both the first and sub-high-pressure nozzles being 4mm, a water pump of 12.5 cubic meters per hour is used, and a single autoclave takes about 5 minutes and uses about 2 cubic meters of water to flush out and recover all the quartz waste, significantly reducing the time and water consumption.

[0032] In this embodiment, the outer wall of the high-pressure water pipe interface is provided with an external thread structure that matches the internal thread of the high-pressure water pipe connector. The internal and external threads enable a detachable connection with the high-pressure water pipe connector, simplifying the assembly process and improving assembly efficiency. Of course, other types of detachable connection methods, such as a steel ball locking method, can be used in other embodiments of this utility model. Furthermore, a boss 9 is also provided on the outer wall of the high-pressure water pipe interface. This boss can be used to secure and limit the rotational position of the high-pressure water pipe on the interface, making it easier for the operator to determine whether the high-pressure water pipe has rotated to the correct position. The boss can also be used as a clamping part to facilitate tightening of the high-pressure water pipe.

[0033] In this embodiment, both the first high-pressure nozzle and the sub-high-pressure nozzle are ceramic high-pressure nozzles; using ceramic high-pressure nozzles can play a role in anti-oxidation and corrosion resistance, significantly reducing maintenance costs.

[0034] In other embodiments of this utility model, the number of the first sub-high pressure nozzle and the second sub-high pressure nozzle is not limited, and their number can be adjusted according to actual needs.

[0035] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
