[0002] Aluminum smelting is the process of reducing alumina in aluminum ore into metallic aluminum. During processing, the aluminum ore needs to be crushed and ground to make it easier to react with chemical reagents used in the smelting process. The powdered aluminum ore raw materials often fill the processing workshop with a large amount of dust, so dust suppression nozzles are needed to reduce dust inside the workshop to maintain the working environment inside the workshop; the dust suppression nozzle uses a high-pressure water pump to send water pressure to the nozzle, and the water flows through the nozzle to form tiny water mist particles. Through injection and diffusion, the water mist particles adhere to the surface of the particles, increase the mass and weight of the particles, and make them sink or condense, thereby reducing the concentration of the particles in the air. The current nozzle has the defect that when the nozzle is not used for a long time, impurity particles in the air, especially larger particles, are easy to adhere to the aperture of the dust suppression nozzle and cause blockage, affecting the spray effect. Therefore, it is necessary to provide a dust suppression nozzle for aluminum smelting workshops that can effectively solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figure 1-Figure 3 As shown, this embodiment provides an environmentally friendly dust suppression nozzle for aluminum smelting workshop, including a nozzle 1, a sliding tube 2, a flap 3, an inner bin 11 and a water inlet. The nozzle 1 is used to install and position the entire dust suppression nozzle. The inner bin 11 is arranged in the nozzle 1 to accommodate the sliding of the sliding tube 2. The flap 3 is rotatably connected to the end of the nozzle 1, and is used to cover and seal the opening at the end of the nozzle 1 to prevent dust from entering. A torsion spring 31 is arranged at the rotating connection to provide elastic force after the flap 3 is opened, so as to push the flap 3 to restore the closed state. Furthermore, a nozzle 21 is arranged at the end of the sliding tube 2, and the nozzle 1 opens a water inlet to introduce water source into the inner bin 11. After the water flow is introduced into the inner bin 11, pressure is formed on the sliding tube 2, and the sliding tube 2 is pushed to slide in the inner bin 11 until the nozzle 21 passes through the opening to push open the flap 3, thereby completing the atomization spraying preparation.

[0024] Furthermore, if Figure 1 As shown, a spring 13 is arranged in the inner bin 11, and both ends of the spring 13 are respectively abutted against the sliding tube 2 and the wall of the inner bin 11. Specifically, the spring abuts against the inner wall of the inner bin 11 close to the opening. When the sliding tube 2 is subjected to the water pressure to push the nozzle 21 out of the opening, the spring 13 is deformed into a compressed state. After the dust suppression operation is completed, the water source pressure of the sliding tube 2 is released. After the water pressure is lost, the sliding tube 2 returns to its original position under the rebound force of the spring 13, and the nozzle 21 is retracted into the opening from the outside. The flap 3 covers the opening again under the elastic force of the torsion spring 31, so as to realize dustproof protection for the nozzle 21 when the dust suppression operation is not performed, and prevent dust from adhering to and clogging the nozzle 21.

[0025] Furthermore, if Figure 1-Figure 3As shown, an air supply pipe 12 is provided on the nozzle 1. The air supply pipe 12 is coaxial with the sliding tube 2 and the two are slidably connected. The air supply pipe 12 provides a guide for the movement of the sliding tube 2. The air supply pipe 12 passes through the inner wall of the end of the nozzle 1 and is used to introduce an external high-pressure air source to mix with the water flow to enhance the atomization effect of the nozzle 21.

[0026] Furthermore, if Figure 1 and Figure 3 As shown, the sliding tube 2 includes a water inlet channel 22, a clearance groove 24 and a gas flow channel 25. The two ends of the gas flow channel 25 are connected to the clearance groove 24 and the nozzle 21. The water inlet channel 22 is used to accommodate water flow and form water pressure to push the sliding tube 2, and then the water flow is introduced into the gas flow channel 25. Then the air supply pipe 12 connects the high-pressure gas source to the gas flow channel 25. The gas flow channel 25 is connected to the nozzle 21. After the gas and water flow are mixed, they enter the nozzle 21 under the continuous action of the common pressure to complete the water flow atomization and spray dust suppression operations; further, the clearance groove 24 is coaxial with the air supply pipe 12, and the two are slidably connected, so that the sliding tube 2 slides smoothly along the air supply pipe 12, and the end of the clearance groove 24 is connected to the gas flow channel 25, ensuring that during the sliding process of the sliding tube 2, the end of the air supply pipe 12 is always connected to the gas flow channel 25 through the clearance groove 24; further, the water inlet channel 22 adopts a variable diameter structure, including a first channel with a larger diameter and a second channel with a smaller diameter, the first channel and The second channel adopts an integrated molding structure. The first channel is arranged at one end close to the water inlet of the nozzle 1. The outer wall of the first channel fits the side wall of the inner chamber 11, and the first channel opening is relatively large. The sliding tube 2 is pushed to move by storing water and forming water pressure. The side wall at the connection between the first channel and the second channel shrinks inward to form a step. The water flow forms a larger pressure in the second channel with a smaller diameter. Finally, the second channel conducts the water flow to the gas flow channel 25. Furthermore, the spring 13 is sleeved on the sliding tube 2, and one end abuts against the step. The sliding tube 2 structure set in this embodiment is slidably matched with the air supply pipe 12, and the first channel is set to store water at the same time. Water pressure is used as the power of the sliding tube 2. After the water flow enters the second channel with a smaller diameter, the pressure increases, providing continuous power for entering the gas flow channel 25 and spraying out from the nozzle 21. The sliding tube 2 structure effectively uses the space of the inner chamber 11, and uses water pressure as the power source for the extension and retraction of the sliding tube 2 and the nozzle 21, and can be driven without an additional power source.

[0027] Preferably, if Figure 1 As shown, the diameter of the gas flow channel 25 is smaller than that of the gas supply pipe 12, and a constricted channel for transition is provided at the connection between the two. The constricted channel is funnel-shaped, and the two ends are connected to the gas flow channel 25 and the gas supply pipe 12 respectively.

[0028] Furthermore, if Figure 1 and Figure 2As shown, this embodiment provides a preferred structure of a flap 3, in which the flap 3 adopts an equilateral triangle structure, and a plurality of flaps 3 are provided to be rotatably connected to the end of the nozzle 1, and a torsion spring 31 is provided at the rotating connection to enable the flap 3 to have a self-returning function; further, the flaps 3 are distributed in a circle around the axis of the opening, and are spliced ​​to form a regular polygonal structure when closed, so as to seal the opening, protect the nozzle 21 and other structures in the inner chamber 11, and block the entry of impurities and dust particles in the external air, thereby preventing the nozzle 21 from being blocked at the aperture and affecting the spray effect, without the need for frequent manual maintenance and cleaning.

[0029] Furthermore, if Figure 1 and Figure 3 As shown, this embodiment also includes a one-way valve 251 and a connecting groove 221. The connecting groove 221 is opened in the sliding tube 2 and is used to connect the water inlet channel 22 and the gas flow channel 25. A plurality of connecting grooves 221 are arranged evenly distributed at the end of the water inlet channel 22 to merge the water flow in the water inlet channel 22 into the gas flow channel 25; further, the one-way valve 251 is arranged in the gas flow channel 25. Specifically, with the direction of the gas passing through the gas flow channel 25 as a reference, the one-way valve 251 is arranged in front of the connection point between the connecting groove 221 and the gas flow channel 25, that is, the gas first passes through the one-way valve 251 and then reaches the connection point between the connecting groove 221 and the gas flow channel 25. By setting the one-way valve 251, the water flow can be prevented from flowing back after reaching the gas flow channel 25, and entering the gas supply pipe 12 and the yield groove 24 for accumulation, while ensuring that the high-pressure gas can normally enter the gas flow channel 25 from the gas supply pipe 12, and be atomized and released through the nozzle 21 after being fully mixed.

[0030] Furthermore, if Figure 1 , Figure 3 and Figure 4As shown, the water inlet includes a water inlet hole 14, a spherical groove 141, a filter 4, an elastic pull rope 41 and a hollow ball 42, wherein the water inlet hole 14 is provided on the outer wall of the nozzle 1 for connecting a water pipe to introduce an external high-pressure water source, a spherical groove 141 is provided on the inner wall of the inner chamber 11 to communicate with the water inlet hole 14, and the high-pressure water flows into the inner chamber 11 through the water inlet hole 14 and the spherical groove 141 in sequence; the filter 4 is fixed to the inner wall of the water inlet hole 14, and the filter 4 intercepts and filters impurities in the water source to prevent impurities in the water source from reaching the inner chamber 11 and clogging structures such as the sliding tube 2 and the nozzle 21; further, one side of the filter 4 is fixedly connected to the elastic pull rope 41, and the other end of the elastic pull rope 41 is fixedly connected to the hollow ball 42, and the hollow ball 42 is placed In the spherical slot 141, when the water source is not connected, the elastic pull rope 41 is in a stretched state, and the hollow ball 42 is engaged with the inner wall of the spherical slot 141 under the action of the elastic pull rope 41, blocking the passage between the spherical slot 141 and the water inlet hole 14, and then after use, the hollow ball 42 prevents the water source from overflowing under the action of the water pressure of the inner warehouse 11, preventing the water source from dripping and freezing in winter to affect the safety of site operations; further, when the water source is connected, the water flows into the spherical slot 141 through the water inlet hole 14, forming a pressure impact on the hollow ball 42 and then stretching the elastic pull rope 41. After the hollow ball 42 is separated from the interface of the spherical slot 141, the water flows into the inner warehouse 11 through the spherical slot 141, and then reaches the water inlet channel 22 and the nozzle, completing the atomization and dust suppression.

[0031] Furthermore, if Figure 1 and Figure 2 As shown, a leveling plate 15 is fixedly provided on the surface of the nozzle 1. Four leveling plates 15 are arranged to serve as mounting brackets to fix the nozzle 1. At the same time, the leveling plates 15 are used to facilitate positioning.

[0032] The working principle and use process of the utility model are as follows: when the nozzle is used, the external water pipe injects water into the inner chamber 11 through the water inlet hole 14 and the spherical card slot 141, and the water flow pushes the hollow ball 42 to open the passage between the spherical card slot 141 and the water inlet hole 14. After the water flows normally through the inside of the water inlet channel 22, the water flow in the water inlet channel 22 is merged into the gas flow channel 25 through a plurality of connecting grooves 221, and the air flow output by the air supply pipe 12 enters the gas flow channel 25 through the yield groove 24, and the air flow and the water source are simultaneously merged into the nozzle 21, and the water source is conducted into the nozzle 21 for atomization and release. Release, and as the water pressure pushes the sliding tube 2 to slide forward under the guidance of the air supply pipe 12, the sliding tube 2 squeezes and deforms the spring 13, and the nozzle 21 extends out of the opening at the end of the nozzle 1 under the push of the sliding tube 2, and pushes the flap 3 to flip and start spraying to suppress dust; after use, the water source is disconnected, the water pressure in the inner warehouse 11 is reduced, and the sliding tube 2 drives the nozzle 21 to enter the inner warehouse 11 under the push of the spring 13, and the torsion spring 31 drives the flap 3 to flip and block the opening of the nozzle 1, thereby isolating the inner warehouse 11 from the external environment, preventing dust from clogging the nozzle 21, and ensuring the stability of the subsequent device during use.
