Description

Technical Field

[0001] This utility model relates to the field of incinerator technology, and in particular to a novel incinerator spray gun device. Background Technology

[0002] Traditional desulfurization wastewater treatment methods (such as coal blending and combustion, and crystallization for salt extraction) pose a risk of secondary pollution and fail to meet current environmental standards. For example, while coal blending and combustion are low-cost, they increase the sulfur content in the coal, exacerbating the load on the desulfurization system; although crystallization for salt extraction can recover some salts, the by-product salts are of low purity and limited value. Incinerators, through high-temperature decomposition, completely eliminate organic pollutants, achieving compliant emissions and becoming the inevitable choice for compliant treatment.

[0003] As disclosed in publication number CN217178526U, a spray gun for an incinerator includes a gun body with an inner tube that can move vertically within the gun body. One end of the gun body is a water outlet, and a sealing plate is hinged to the water outlet. A connecting rod is hinged between the inner tube and the sealing plate, and the connecting rod is used to open the sealing plate when the inner tube moves downward. This application can improve the problem that harmful gases or incinerator flames can easily damage the spray gun.

[0004] This patented technology can prevent the incinerator flame from easily damaging the spray gun. However, the nozzles in current devices do not have a quick-replacement function. When the nozzle needs to be replaced due to wear, blockage, or corrosion, the traditional method requires disassembling the entire spray gun or part of the gun body. Without a quick-replacement design, maintenance personnel need to spend more time locating the fault, disassembling parts, cleaning residue, and reinstalling, resulting in a significant increase in the time required for each maintenance. Utility Model Content

[0005] The purpose of this invention is to address the problem that current spray nozzles lack a quick-replacement function. When a spray nozzle needs replacement due to wear, blockage, or corrosion, the traditional method requires disassembling the entire spray gun or part of the gun body. Without a quick-replacement design, maintenance personnel need to spend more time locating the fault, disassembling parts, cleaning residue, and reinstalling, resulting in a significant increase in the time required for each maintenance session.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel incinerator spray gun device, comprising a spray gun body, a convenient replacement component provided at the front end of the spray gun body, the convenient replacement component comprising a nozzle body, slots provided at the upper and lower ends of the rear side of the nozzle body, slots provided inside the upper and lower ends of the spray gun body, two sets of springs connected inside the slots, push plates connected to the bottom of the two sets of springs, insert blocks connected to the bottom surface of the push plates, a connecting plate connected to the top center of the push plates, a pull block connected to the top of the connecting plate, an insert block connected to the bottom of the push plates, and a groove provided at the matching position of the spray gun body and the nozzle body.

[0007] Furthermore, the rear end of the spray gun body is connected to the groove, and the surface of the insert block is provided with an oblique opening.

[0008] Furthermore, the position and size of the insert block match the position and size of the slot, and the insert block and the slot form a mating connection.

[0009] Furthermore, the push plate and the spring form an elastic structure, and the outer surface of the push plate is in contact with the inner wall of the slot.

[0010] Furthermore, a movable telescopic assembly is connected to the bottom of the spray gun body. The movable telescopic assembly includes a fixed frame, and grooves are provided on both sides of the fixed frame.

[0011] Furthermore, a one-way screw is inserted inside the fixing frame, one end of the one-way screw is connected to a bearing, and the other end of the one-way screw is connected to the output end of a servo motor.

[0012] Furthermore, a movable block is connected to the surface of the unidirectional screw, a threaded hole is opened through the interior of the movable block, and a slider is connected to the top of the movable block.

[0013] Furthermore, a movable frame is connected to the bottom of the slider, and a sliding connection is formed between the slider and the slide groove. The one-way screw is threadedly connected to the movable block through a threaded hole.

[0014] Furthermore, the output end of the servo motor is fixedly connected to the unidirectional screw, the movable frame is arc-shaped, and the movable frame is fixedly connected to the spray gun body.

[0015] Furthermore, the servo motor is electrically connected to an external power source via a control switch, and the one-way screw and bearing form a rotatable connection.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, such as Figure 1 - Figure 4 As shown, this utility model provides a novel incinerator spray gun device, including a spray gun body 1. A convenient replacement component 2 is provided at the front end of the spray gun body 1. The convenient replacement component 2 includes a nozzle body 201. Slots 202 are provided at both the upper and lower rear ends of the nozzle body 201. Grooves 203 are provided inside both the upper and lower ends of the spray gun body 1. Two sets of springs 204 are connected inside the grooves 203. Push plates 207 are connected to the bottom of the two sets of springs 204. Insert blocks 208 are connected to the bottom surface of the push plates 207. A connecting plate 205 is connected to the center of the top of the push plates 207. A pull block 206 is connected to the top of the connecting plate 205, and an insert block 208 is connected to the bottom of the push plate 207. A groove 209 is provided at the matching position of the spray gun body 1 and the nozzle body 201. The rear end of the spray gun body 1 and the groove 209 form an interlocking connection. A bevel is provided on the surface of the insert block 208. The position and size of the insert block 208 match the position and size of the slot 202. The insert block 208 and the slot 202 form an interlocking connection. An elastic structure is formed between the push plate 207 and the spring 204. The outer surface of the push plate 207 is in contact with the inner wall of the slot 203.

[0028] The effect achieved in Embodiment 1 is that when the nozzle body 201 needs to be cleaned or replaced, it needs to be disassembled first. During disassembly, two sets of pull blocks 206 can be pulled up and down simultaneously. The pull blocks 206 will drive the push plate 207 through the connecting plate 205 to compress the spring 204. At this time, the insert block 208 will also be pulled out of the slot 202 of the nozzle body 201. Then, the nozzle body 201 is pushed outward so that it is pulled out of the groove 209 in the spray gun body 1, thus completing the disassembly. When the nozzle body 201 is cleaned or a new nozzle body 201 is installed, the nozzle body 201 can be directly pushed into the groove 209. When the angled opening of the insert 208 is squeezed, it will automatically retract. After the nozzle body 201 is fully pushed into the groove 209 of the spray gun body 1, the insert 208 will be automatically pushed into the slot 202 under the action of the spring 204, thus quickly fixing the nozzle body 201 and avoiding the problem that traditional fixing methods cannot be quickly disassembled and assembled.

[0029] Example 2, as Figure 1 and Figure 5 As shown, a movable telescopic assembly 3 is connected to the bottom of the spray gun body 1. The movable telescopic assembly 3 includes a fixed frame 301. Slide grooves 302 are provided on both sides of the fixed frame 301. A one-way screw 303 is inserted into the fixed frame 301. One end of the one-way screw 303 is connected to a bearing 304, and the other end is connected to the output end of a servo motor 305. A moving block 306 is connected to the surface of the one-way screw 303. A threaded hole 307 is provided through the interior of the moving block 306. A sliding block is connected to the top of the moving block 306. The bottom of block 308 and slider 308 is connected to a movable frame 309. Sliding connection is formed between slider 308 and slide groove 302. One-way screw 303 is threadedly connected to movable block 306 through threaded hole 307. Output end of servo motor 305 is fixedly connected to one-way screw 303. Movable frame 309 is arc-shaped and fixedly connected to spray gun body 1. Servo motor 305 is electrically connected to external power supply through control switch. One-way screw 303 is rotatably connected to bearing 304.

[0030] The effect achieved in Embodiment 2 is that after the spray gun body 1 has finished working, the forward rotation function of the servo motor 305 can be activated, so that the output end of the servo motor 305 can drive the one-way screw 303 to rotate forward. When the one-way screw 303 rotates forward, it will also rotate forward through the threaded hole 307 and the moving block 306. In this way, the moving block 306 is driven to move backward, so that the slider 308 can move in the slide groove 302. And through the moving frame 309, the spray gun body 1 is driven to move backward, so that the spray gun body 1 can retract to a safe position and close the gate to block the high temperature radiation inside the furnace. When it is needed, the reverse rotation function of the output end of the servo motor 305 is activated, so that the moving block 306 can drive the spray gun body 1 to move forward through the reverse thread rotation, so that the spray gun body 1 can be moved to the working area. By telescopic movement, the service life of the spray gun body 1 is improved.

[0031] Working principle: When replacing or cleaning the nozzle body 201, the two sets of pull blocks 206 can be pulled up and down simultaneously to pull the insert block 208 out of the slot 202 of the nozzle body 201. Then, the nozzle body 201 is pulled outward to complete the disassembly. When installing a new nozzle body 201, it can be pushed into the spray gun body 1. The oblique opening of the insert block 208 will automatically retract under pressure. When the nozzle body 201 is fully pushed into the spray gun body 1, it can be automatically fixed by the insert block 208, avoiding the problem of not being able to quickly disassemble and assemble using traditional fixing methods. When the spray gun body 1 is in use, the reverse function of the servo motor 305 can be turned on. The reverse screw rotation will drive the spray gun body 1 to extend into the incinerator. The spray gun body 1 can then be put into operation. After the operation is completed, the forward rotation function of the servo motor 305 can be turned on to drive the spray gun body 1 to extend and retract backward, so that the spray gun body 1 is retracted to a safe position. At the same time, the gate is closed to block the high temperature radiation inside the furnace and improve the service life of the spray gun body 1.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
