Description

Technical Field

[0001] This invention relates to the field of nozzle technology, specifically to a hybrid nozzle. Background Technology

[0002] The nozzle is suitable for flue gas desulfurization systems. It atomizes the desulfurizing agent under the action of a pump and sprays it into the desulfurization tower, so that the desulfurizing agent comes into contact with sulfur dioxide and reacts to form calcium sulfate, thereby removing sulfur dioxide from the flue gas. In addition to being used in traditional desulfurization systems, it can also be widely used as an energy-saving refractory material in high-temperature kilns in industries such as sanitary ceramics, daily-use ceramics, electrical ceramics, magnetic materials, microcrystalline stone, powder metallurgy, and steel heat treatment.

[0003] Existing spraying equipment typically uses a spray gun to spray atomized media. To achieve an angled spray pattern and a larger contact area, spiral nozzles are available on the market. The spiral shape at the outer end of the nozzle effectively guides the airflow. Most of these nozzles are attached to the spray gun via a spiral rotation. During subsequent maintenance and replacement, the nozzle needs to be disassembled. When using tools for disassembly, the outer end of the spiral is easily damaged by contact or impact. Moreover, this type of nozzle is difficult to place later, and its sharp shape can easily cause injury to personnel. Therefore, we propose a hybrid nozzle. Summary of the Invention

[0004] The purpose of this invention is to provide a mixing nozzle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mixing nozzle, comprising a docking portion that docks with a spray gun; further comprising a docking ring platform installed at the outer end of the docking portion, wherein a spiral nozzle is fixed at the outer end of the docking ring platform, and an insertion groove is formed on the outer side of the docking ring platform; and a protective component that is sleeved on the outer side of the spiral nozzle and is engaged with the insertion groove.

[0006] Preferably, the protective component includes a protective sleeve and a snap ring fixed to the outer end of the protective sleeve. The outer end of the snap ring is fixed with a snap-fit ​​unit that is compatible with the insertion groove. The protective component provides protection for the spiral nozzle.

[0007] Preferably, there are two insertion slots, which are distributed on the outside of the docking ring platform. The insertion slot includes an insertion slot, a locking slot and a stop slot. The locking slot and the stop slot are interconnected with the insertion slot and are distributed on both sides of the insertion slot.

[0008] Preferably, the snap-fit ​​unit includes an insert plate fixed to the snap-fit ​​ring, a snap plate adapted to the snap-fit ​​groove is fixed on one side of the insert plate, and an abutment plate adapted to the abutment groove is fixed on the other side of the insert plate. The snap-fit ​​unit is designed to snap into the insert groove.

[0009] Preferably, the snap-fit ​​unit further includes a locking element, which includes a locking rod. The snap-fit ​​plate has an installation groove for sliding the locking rod, and the groove has a snap-fit ​​hole for limiting the locking rod. A compression spring that abuts against the locking rod is fixed in the installation groove. The snap-fit ​​unit is designed to snap-fit ​​the insert plate, which facilitates the fixing of the protective sleeve to the outside of the spiral nozzle.

[0010] Preferably, the cross-sectional shape of the mounting groove is convex, and the outer side of the locking rod is slidably inserted into the inner wall of the small-diameter port of the mounting groove. The inner end of the locking rod is fixed with a limiting plate that is slidably inserted into the inner wall of the large-diameter port of the mounting groove, and the limiting plate is fixed to the outer end of the compression spring. The locking rod is designed to engage with the locking hole, thereby satisfying the engagement of the insert plate and the insertion groove.

[0011] Preferably, the outer end of the locking rod and the outer sides of the locking plate, insert plate and abutment are all equipped with ball bearings. The inner walls of the locking groove and the insertion groove are provided with track grooves that communicate with the locking hole. The ball bearings are designed to reduce friction, thereby facilitating rotation.

[0012] Preferably, the locking hole is a through hole, and the outer end of the locking hole is fixed with a mounting ring flush with the outer wall of the docking ring platform. A push-opening rod is inserted into the mounting ring, and the inner end of the push-opening rod is fixed with a mating platform that slides and engages with the inner wall of the locking hole. A notch adapted to the ball is provided on one side of the mating platform. The design of the push-opening rod allows the locking rod to disengage from the locking hole after the docking part is docked with the spray gun, making it convenient to remove the fastening ring.

[0013] Preferably, a limiting piece is fixed at the end of the push rod away from the abutting platform, and a storage groove adapted to the limiting piece is opened on the outer side of the mounting ring. A toothed block that magnetically attracts each other is provided between the limiting piece and the storage groove. The limiting piece is designed to fit snugly with the storage groove, which can prevent the push rod from disengaging from the locking hole.

[0014] Preferably, the arc lengths of the insert plate, the card plate, and the abutment plate are consistent with the arc length of the insertion slot, and the outer side of the insert plate is fixed with an anti-slip plate that facilitates rotation. The design of the anti-slip plate makes the rotation of the fastening ring more convenient.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention optimizes the existing spiral nozzle by designing a docking ring platform that connects with the protective component. This allows the spiral nozzle to be protected during disassembly by using the protective component to cover the outside of the spiral nozzle, thus preventing damage from impacts during disassembly and replacement.

[0017] 2. This invention incorporates a snap-fit ​​unit within the protective component, allowing the snap-fit ​​ring to lock securely onto the outside of the spiral nozzle after docking. This prevents accidental contact and damage during the placement of the spiral nozzle. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figures 1-5 The figure shows a mixing nozzle, including a docking part 1, which docks with a spray gun; it also includes a docking ring platform 2 installed on the outer end of the docking part 1, with a spiral nozzle 3 fixed on the outer end of the docking ring platform 2, and an insertion groove 4 opened on the outer side of the docking ring platform 2; and a protective component 5, which is sleeved on the outer side of the spiral nozzle 3 and is connected to the insertion groove 4.

[0032] Furthermore, there are two insertion slots 4, which are distributed on the outside of the docking ring platform 2. The insertion slot 4 includes an insertion slot 9, a locking slot 10 and abutment slot 11. The locking slot 10 and abutment slot 11 are connected to the insertion slot 9 and are distributed on both sides of the insertion slot 9.

[0033] Please see Figure 3 , Figure 6 and Figure 8 The protective component 5 shown in the figure includes a protective sleeve 6 and a fastening ring 7 fixed to the outer end of the protective sleeve 6. The outer end of the fastening ring 7 is fixed with a snap-fit ​​unit 8 that is adapted to the insertion groove 4.

[0034] Furthermore, the snap-fit ​​unit 8 includes an insert plate 12 fixed to the snap-fit ​​ring 7. One side of the insert plate 12 is fixed with a snap plate 13 that is adapted to the snap-fit ​​groove 10, and the other side of the insert plate 12 is fixed with an abutment plate 14 that is adapted to the abutment groove 11.

[0035] The principle of the connection between the protective component 5 and the insertion groove 4 on the outer side of the docking ring 2 is as follows: First, the operator holds the protective sleeve 6, causing the insertion plate 12 on one side of the fastening ring 7 to align with the insertion groove 4. Figure 3As shown in the diagram, personnel then insert the plate 12 until it is flush with the bottom of the insertion slot 4. If personnel need to disassemble the nozzle, they rotate the fastening ring 7 so that the abutment 14 on one side of the plate 12 is flush with the abutment slot 11. Then, they continue to rotate the plate 12 so that the fastening ring 7 drives the docking ring platform 2 to rotate, thereby disengaging the docking part 1 from the spray gun thread and completing the disassembly of the nozzle. When the nozzle is replaced, its spiral part is protected by the protective sleeve 6 to prevent damage from impacts.

[0036] It should also be noted that in order to ensure that the insert plate 12 can smoothly mate with the insertion slot 9, the sum of the arc lengths of the insert plate 12, the retaining plate 13 and the abutment plate 14 are designed to be consistent with the arc length of the insertion slot 9, and the outer side of the insert plate 12 is fixed with an anti-slip plate 28 that facilitates rotation.

[0037] Example 2

[0038] Please see Figures 5-8 This embodiment further illustrates Example 1, with the difference being that the snap-fit ​​unit 8 also includes a locking member 15.

[0039] Specifically, the snap-fit ​​unit 8 also includes a locking member 15, which includes a locking rod 16. The snap-fit ​​plate 13 has a mounting groove 17 for sliding the locking rod 16. The snap-fit ​​groove 10 has a snap-fit ​​hole 18 for limiting the locking rod 16. A compression spring 19 that abuts against the locking rod 16 is fixed in the mounting groove 17.

[0040] Furthermore, in order to ensure that the locking rod 16 can move smoothly within the mounting groove 17 without dislodging from it, the mounting groove 17 is designed with a convex cross-sectional shape. The outer side of the locking rod 16 is slidably inserted into the inner wall of the small-diameter port of the mounting groove 17, and the inner end of the locking rod 16 is fixed with a limiting plate 20 that is slidably inserted into the inner wall of the large-diameter port of the mounting groove 17. The limiting plate 20 is fixed to the outer end of the compression spring 19.

[0041] Furthermore, in order to make the insert plate 12 and the locking plate 13 move smoothly, ball bearings 21 are installed on the outer end of the locking rod 16 and on the outer side of the locking plate 13, the insert plate 12 and the abutment plate 14. Track grooves 22 that communicate with the locking hole 18 are opened on the inner wall of the locking groove 10 and the insertion groove 9.

[0042] In summary, after the personnel disassembled the spiral nozzle 3, the position of the insert plate 12 within the insertion slot 4 was as follows: Figure 2 As shown, the operator rotates the buckle ring 7 in the opposite direction, so that the insertion plate 12 is positioned as shown in the insertion slot 4. Figure 1As shown, at this time, the card plate 13 is in contact with the card slot 10, and after they are in place, the locking rod 16 is pushed out by the compression spring 19 and inserted into the card hole 18, thereby completing the locking and limiting of the insert plate 12, so that the protective sleeve 6 can be securely fitted on the outside of the spiral nozzle 3, so that the nozzle can play a protective role when placed, and avoid injury caused by accidental contact with personnel.

[0043] Example 3

[0044] Please see Figure 9 and Figure 10 This embodiment further illustrates other embodiments, the difference being that a top-opening rod 24 is added inside the locking hole 18, so that the locking rod 16 can automatically disengage from the locking hole 18.

[0045] Specifically, the locking hole 18 is a through hole, and the outer end of the locking hole 18 is fixed with a mounting ring 23 that is flush with the outer wall of the docking ring platform 2. A push-opening rod 24 is inserted into the mounting ring 23, and the inner end of the push-opening rod 24 is fixed with a mating platform 25 that slides and docks with the inner wall of the locking hole 18. A notch adapted to the ball 21 is provided on one side of the mating platform 25.

[0046] Furthermore, a limiting piece 26 is fixed at the end of the push-opening rod 24 away from the abutting platform 25. A storage groove 27 that matches the limiting piece 26 is opened on the outer side of the mounting ring 23. A toothed block that magnetically attracts each other is provided between the limiting piece 26 and the storage groove 27. The attraction force of the magnetic block between the limiting piece 26 and the storage groove 27 is less than the elastic force of the compression spring 19.

[0047] It should be noted that when installing the nozzle, the operator can directly pick up the nozzle covered with the protective sleeve 6, align the docking part 1 with the spray gun, and then rotate the fastening ring 7. During the rotation, the docking ring 2 will come into contact with the docking end of the spray gun until they abut against each other, causing the push-opening rod 24 to be pushed into the locking hole 18, thereby lifting the locking rod 16 and disengaging it from the locking hole 18. Afterwards, the operator can rotate the fastening ring 7 in the opposite direction, which will easily allow the insert plate 12 to be pulled out from the insertion slot 9.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0049] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
