Description

Technical Field

[0001] This utility model relates to the field of liquid atomization technology, specifically to an anti-clogging spray tower atomizing nozzle. Background Technology

[0002] Atomizing nozzles are a key component used in spray towers. They atomize liquids (usually water or solutions containing chemical reagents) into fine droplets to increase the contact area between the liquid and the gas, thereby improving absorption, cooling, or washing efficiency.

[0003] Chinese Patent Announcement No. CN217092886U discloses a spray tower atomizing nozzle. This patent connects to a water pipe, and high-pressure water is sprayed from the nozzle part of the built-in spray pipe to open the fan-shaped plate. The water sprays out from the gaps in the fan-shaped plate. When the water stops, the fan-shaped plate returns to its original position, which facilitates the resealing of the nozzle part and can prevent the nozzle part from becoming clogged.

[0004] In existing technologies, due to the presence of many impurities in the water or the tendency for scale to form, the movement of the fan-shaped plate may become stuck or fail to reset properly, affecting the normal opening of the nozzles. Long-term operation may result in uneven spraying, local blockage, or leakage, affecting the normal use of the spray tower's atomizing nozzles.

[0005] Based on this, the present invention designs an anti-clogging spray tower atomizing nozzle to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an anti-clogging spray tower atomizing nozzle.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A clog-resistant spray tower atomizing nozzle includes an atomizing nozzle, one end of which is fixedly connected to a connecting pipe. A filter assembly is installed inside the connecting pipe, and an anti-clogging component is installed in the inner cavity of the connecting pipe. The filter assembly includes a slide rail installed in the inner cavity of the connecting pipe, a filter screen slidably connected inside the slide rail, and multiple metal springs fixedly connected to the outer surface of the filter screen. The anti-clogging component includes an electromagnet fixedly connected to the inner cavity of the filter screen, an elastic rod fixedly connected to the side of the filter screen, a clogging ball fixedly connected to one end of the elastic rod, and a magnetic block fixedly connected to the inner cavity of the clogging ball. The magnetic block and the electromagnet are magnetically connected.

[0008] Furthermore, the inner cavity of the atomizing nozzle is equipped with a spray pipe, the outer surface of the connecting pipe is fixedly connected with an external thread, and the outer surface of the connecting pipe is equipped with a flange.

[0009] Furthermore, a limiting block is installed inside the nozzle cavity, and the outer surface of the blocking ball abuts against the limiting block.

[0010] Furthermore, the filter assembly includes a buffer ring mounted on the outer surface of the filter screen, with a fixing ring fixedly connected to the side of the buffer ring, and the buffer ring is made of an elastic material.

[0011] Furthermore, the inner cavities of the fixing ring, buffer ring, and connecting tube are provided with multiple positioning holes, and positioning rods are engaged within the inner cavities of the positioning holes.

[0012] Furthermore, the outer surfaces of both the electromagnet and the magnetic block are fitted with waterproof sleeves.

[0013] Furthermore, the anti-clogging component includes a silicone layer fixedly connected to the outer surface of the clogging ball, and an anti-scaling coating is fixedly connected to the outer surface of the silicone layer. The clogging ball abuts against the inner cavity of the nozzle.

[0014] Furthermore, a spiral flow channel is installed between the atomizing nozzle and the connecting pipe. Beneficial effects

[0015] (1) When the spray is started, the electromagnet is energized to generate a magnetic field with the same polarity as the magnetic block. The two repel each other due to the repulsion of like poles, which causes the magnetic block to drive the blocking ball out of the nozzle cavity and open the flow channel. After the spray stops, the electromagnet is de-energized, the repulsion disappears, the blocking ball is quickly reset by the elastic rod and tightly abuts against the nozzle outlet, and is precisely positioned by the limit block to form a reliable physical seal. This effectively solves the problems of fan plate movement jamming or nozzle leakage caused by the traditional nozzle when there are many impurities in the water or the water quality is prone to scaling, and prevents external impurities from flowing back in.

[0016] (2) By changing the magnetic field of the electromagnet, the electromagnet generates a magnetic field opposite to that of the magnetic block. The two attract each other due to their opposite polarity, causing the magnetic block to drive the blockage ball to hit the filter screen. Combined with the elastic support structure formed by the metal spring and the buffer ring, the vibration amplitude is further amplified, realizing the automatic shaking and dust removal of the filter screen. This allows the filter screen to actively remove the deposits on the surface of the filter screen after spraying, effectively preventing the filter screen from being blocked due to particle accumulation.

[0017] (3) By guiding the water flow in the spiral channel inside the nozzle to form a high-speed swirling flow, the centrifugal atomization effect is enhanced, and the droplet fineness and distribution uniformity are improved. At the same time, a silicone layer and an anti-scaling coating are integrated on the surface of the clogging ball to improve the sealing surface fit and inhibit the adhesion of scale and pollutants. Combined with the cooperation of the slide rail, positioning rod and fixing ring, the filter screen and anti-clogging components can be pulled out and quickly reset. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5A clog-resistant spray tower atomizing nozzle includes an atomizing nozzle 1, one end of which is fixedly connected to a connecting pipe 101, and a filter assembly 2 is installed inside the connecting pipe 101.

[0024] In this embodiment of the present invention, the filter assembly 2 includes a slide rail 201 installed in the inner cavity of the connecting pipe 101. A filter screen 202 is slidably connected inside the slide rail 201. A plurality of metal springs 204 are fixedly connected to the outer surface of the filter screen 202. A spray pipe 103 is installed in the inner cavity of the atomizing nozzle 1. An external thread 102 is fixedly connected to the outer surface of the connecting pipe 101. The filter assembly 2 includes a buffer ring 206 installed on the outer surface of the filter screen 202. A fixing ring 205 is fixedly connected to the side of the buffer ring 206. The buffer ring 206 is made of elastic material. A plurality of positioning holes 207 are opened in the inner cavity of the fixing ring 205, the buffer ring 206 and the connecting pipe 101. A positioning rod 208 is snapped into the inner cavity of the positioning hole 207. A flange sleeve 308 is installed on the outer surface of the connecting pipe 101.

[0025] In one embodiment of this utility model, high-pressure water is initiated and enters the interior through the connecting pipe 101. The filter screen 202 intercepts particulate impurities in the water, preventing them from entering the atomizing nozzle 1. During this process, the impact of the water flow on the filter screen 202 causes the metal spring 204 and the buffer ring 206 to work together to generate a slight vibration, which helps to prevent the pores of the filter screen 202 from becoming clogged. If the filter screen 202 needs to be replaced or cleaned, the connecting pipe 101 is separated from the spray tower. Then, multiple positioning rods 208 are removed from the positioning holes 207 to release the fixed limit on the buffer ring 206, the fixing ring 205 and the filter screen 202. Then, the filter screen 202 and the anti-clogging component 3 are removed along the track of the slide rail 201 for cleaning or replacement of the filter screen 202.

[0026] In some embodiments, such as Figure 1-5 As shown, in a preferred embodiment of the present invention, the inner cavity of the connecting pipe 101 is equipped with an anti-blocking component 3.

[0027] In this embodiment of the present invention, the anti-clogging component 3 includes an electromagnet 301 fixedly connected to the inner cavity of the filter screen 202, an elastic rod 307 fixedly connected to the side of the filter screen 202, a clogging ball 304 fixedly connected to one end of the elastic rod 307, a magnetic block 302 fixedly connected to the inner cavity of the clogging ball 304, the magnetic block 302 and the electromagnet 301 being magnetically connected, a limiting block 309 installed in the inner cavity of the nozzle 103, the outer surface of the clogging ball 304 abutting against the limiting block 309, waterproof sleeves installed on the outer surfaces of the electromagnet 301 and the magnetic block 302, the anti-clogging component 3 includes a silicone layer 305 fixedly connected to the outer surface of the clogging ball 304, an anti-scaling coating 306 fixedly connected to the outer surface of the silicone layer 305, the clogging ball 304 abutting against the inner cavity of the nozzle 103, and a spiral flow channel 303 installed between the atomizing nozzle 1 and the connecting pipe 101.

[0028] In one embodiment of this utility model, as the water continues to flow forward and enters the spiral channel 303, a high-speed rotating vortex is formed through the spiral channel 303. Subsequently, the water impacts the blocking ball 304. At the same time, the electromagnet 301 is activated to generate the same magnetic field as the magnetic block 302, causing the magnetic block 302 inside the blocking ball 304 to move the elastic rod 307 so as to open the nozzle 103. The high-pressure rotating water flow is then sprayed out from the atomizing nozzle 1 through the nozzle 103. When the spraying stops, the electromagnet 301 is immediately de-energized, so that the blocking ball 304 is reset along with the elastic rod 307, so that it is tightly abutted against the outlet of the inner cavity of the nozzle 103 again, and its position is limited by the limiting block 309.

[0029] The working principle of this utility model is as follows: In use, the electromagnet 301 is first connected to an external power supply and controller via wires to ensure normal power supply. When spraying is required on the spray tower, high-pressure water is activated and enters the interior through the connecting pipe 101. The water passes through the filter screen 202, intercepting particulate impurities in the water and preventing them from entering the atomizing nozzle 1. During this process, the impact of the water flow on the filter screen 202 causes the metal spring 204 and the buffer ring 206 to work together, generating slight vibrations to help prevent clogging of the filter screen 202 pores. As the water continues to flow forward, it enters the spiral flow channel 303, where it passes through the spiral flow... The spiral channel 303 forms a high-speed rotating vortex, which significantly enhances the centrifugal motion of the liquid. Subsequently, the water flow impacts the blocking ball 304. At the same time, the power supply and controller of the electromagnet 301 are activated, so that the electromagnet 301 generates the same magnetic field as the magnetic block 302. This causes the magnetic block 302 in the blocking ball 304 to move the elastic rod 307, so as to open the nozzle 103. The high-pressure rotating water flow then passes through the nozzle 103 and is sprayed out from the atomizing nozzle 1. Utilizing the swirling effect formed by the spiral channel 303, the liquid is efficiently atomized into a fine and uniform cone spray, achieving good gas-liquid contact and exhaust gas treatment effect.

[0030] When the spraying stops, the electromagnet 301 is immediately de-energized, causing the clogging ball 304 to reset along with the elastic rod 307, making it tightly abut against the outlet of the nozzle 103. The position is limited by the limiting block 309, thus achieving a physical seal and effectively preventing external dust or crystals from flowing back into the atomizing nozzle 1 and causing blockage. After the work is completed, the electromagnet 301 is activated to periodically generate a magnetic field opposite to that of the magnetic block 302, causing the magnetic block 302 to attract the electromagnet 301, thereby driving the clogging ball 304 to strike the filter screen 202. The elastic support structure composed of the metal spring 204 and the buffer ring 206 further amplifies the vibration effect, realizing automatic shaking and dust removal of the filter screen 202 and preventing long-term accumulation of impurities. In addition, the silicone layer 305 and anti-scaling coating 306 on the surface of the clogging ball 304 not only improve the sealing performance but also reduce the adhesion of scale and pollutants.

[0031] When it is necessary to replace or clean the filter screen 202, disconnect the connecting pipe 101 from the spray tower. Then, remove the multiple positioning rods 208 from the positioning holes 207 to release the fixed limit on the buffer ring 206, the fixing ring 205 and the filter screen 202. Then, remove the filter screen 202 and the anti-clogging component 3 along the track of the slide rail 201. During this process, the clogging ball 304 moves out synchronously with the filter screen 202 through the elastic deformation of the silicone layer 305, which makes it convenient for the staff to clean or replace the filter screen 202. At the same time, the anti-clogging component 3 can be inspected and cleaned. The reverse operation can be used to quickly install it.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
