Description

Technical Field

[0001] The utility model belongs to the technical field of water mist machines, and in particular relates to a water mist machine for making dust and mud balls in a rotary hearth furnace. Background Art

[0002] Rotary hearth furnace dust sludge pelletizing is an important part of the rotary hearth furnace process. It is mainly used to treat the iron-containing dust sludge generated in the steel production process. Disc pelletizing is to pelletize the mixed dust sludge through a disc pelletizing machine. The disc pelletizing machine rotates and uses the action of a scraper to make the dust sludge roll on the disc and gradually form pellets. In the pelletizing process, water mist is generated by a water mist machine. When the water mist is sprayed into the air, it can directly contact the dust in the air, thereby playing a role in dust reduction.

[0003] A water mist jet machine is disclosed in the patent application No. 201310056888.6. The application utilizes the Venturi principle. Under the action of high-speed airflow, the first throat and the second throat form negative pressure in their cavities, resulting in a siphon phenomenon, and water is sucked into the first throat and the second throat from the first water nozzle, the second water nozzle and the third water nozzle. The sucked water is atomized under the impact of the high-speed airflow to form a uniform and fine water mist that is sprayed out from the nozzle, thereby reducing the requirements for water pressure and the reliance on the water pump, and reducing energy consumption. In combination with the above application and in connection with the existing water mist machine structure, the existing water mist machine usually has a limited spray distance when the water mist is sprayed during the spraying process. If the water mist machine is placed at a distance from the working equipment, the sprayed water mist is easy to disperse, thereby affecting the dust reduction effect and affecting the practicability of the device. For this reason, we propose a water mist machine for rotary hearth furnace dust sludge pelletizing. Utility Model Content

[0004] The utility model aims to provide a water mist machine for rotary hearth furnace dust and sludge pelletizing, so as to solve the problem that the existing water mist machine mentioned in the above background technology is that during the spraying process, the spraying distance of the water mist is usually limited. If the water mist machine is placed at a certain distance from the working equipment, the sprayed water mist is easy to disperse, thereby affecting the dust reduction effect and affecting the practicability of the device.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water mist machine for making dust and sludge balls in a rotary hearth furnace, comprising a water mist machine case, a water inlet pipe is installed on one side of the water mist machine case, a moving roller is installed on the bottom of the water mist machine case, a steering support frame is installed on the top of the water mist machine case, a water mist cylinder is installed on the top of the steering support frame, an angle support frame is installed on one side of the steering support frame, and the other end of the angle support frame is installed on the bottom of the water mist cylinder, a nozzle mounting seat is installed at one end of the water mist cylinder, a spray head is installed on the inner side of the nozzle mounting seat, and a preheating ring is arranged on the spray head, an extension nozzle is installed on the outer side of the nozzle mounting seat, a guide groove is opened on the surface of the extension nozzle, two guide screws are symmetrically installed on the top and bottom of the nozzle mounting seat, and a fixing bolt is installed on the guide screw.

[0006] Preferably, the extended nozzle and the nozzle mounting seat are slidably mounted via a guide groove and a guide screw.

At the same time, after the preheating ring is installed, the mica sheet is attached to the spray head.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) By setting up the structure with the adjustable extension nozzle, during the ball making process, if the water mist machine is used for dust reduction spraying, if there is a certain distance between the placement point of the water mist machine and the equipment, the extension of the extension nozzle can be adjusted to increase the distance of the sprayed water mist, so that the sprayed water mist can better contact the dust generated during the processing, play a better role in dust reduction, avoid the dispersion of water mist, and thus improve the dust reduction effect of the device;

[0013] (2) At the same time, when the device is used in cold weather, the water mist is easily condensed and frozen at the spray head after being sprayed out.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] See also Figure 1 , Figure 2 and Figure 3The utility model provides a technical solution: the water mist machine atomizes water molecules into tiny water droplets to form water mist, and the water mist is evenly sprayed into the air through a nozzle, quickly contacts with dust in the air, causes it to settle and plays the role of purifying the air. A water mist machine for making dust and mud balls in a rotary furnace comprises a water mist machine box 100, a water inlet pipe 101 is installed on one side of the water mist machine box 100, a moving roller 102 is installed on the bottom of the water mist machine box 100, and a rotatable and adjustable steering support frame 103 is installed on the top of the water mist machine box 100, and the water mist cylinder 105 in the horizontal direction can be adjusted by the steering support frame 103. The spraying angle is adjusted by adjusting the spray head 106 on the inner side of the spray head 106, and the spray head 106 is provided with a preheating ring 300, and the outer side of the spray head mounting seat 107 is provided with an extension nozzle 106. The nozzle 200 has a guide groove 201 on its surface, and two guide screws 202 are symmetrically mounted on the top and bottom of the nozzle mounting seat 107, and fixing bolts 203 are mounted on the guide screws 202. In the rotary furnace dust and mud pelletizing process, when the water mist machine in the application is used for spraying and dust reduction, the water mist is sprayed out from the spray head 106 by pressure, and the airflow generated in the water mist cylinder 105 increases the spraying distance. In addition, during the spraying process, the horizontal angle can be adjusted by rotating the steering support frame 103, and the vertical angle can be adjusted by the angle support frame 104. If the device is placed at a certain distance from the working equipment during spraying, the sprayed water mist is easy to disperse in the air, thereby affecting the dust reduction effect. Through the set extension nozzle 200, if the spray distance and the equipment spacing are too large during use, the fixing bolt 203 on the guide screw 202 can be loosened, and then the limited guide screw 202 and the guide slide groove 201 can be slid and extended to adjust the extension length of the extension nozzle 200. After the length is adjusted, the acceleration distance when the water mist is sprayed is increased, thereby increasing the spraying distance of the water mist, achieving a better dust reduction effect, thereby improving the practicability of the device.

[0021] Specifically, the extended nozzle 200 and the nozzle mounting seat 107 are slidably installed through a guide groove 201 and a guide screw 202. The sliding method can adjust the extension and retraction of the extended nozzle 200 according to needs to meet different usage requirements. In addition, the extended nozzle 200 and the nozzle mounting seat 107 are also screwed and fixed by fixing bolts 203 installed on two symmetrical guide screws 202, which facilitates adjustment and improves installation stability.

[0023] See also Figure 1 and Figure 3 The utility model provides a technical solution: a water mist machine for making dust and mud balls in a rotary hearth furnace, wherein a plurality of through nozzle assembly holes 301 are provided in an internal array of a preheating ring 300, a mica sheet 302 is fixedly installed on the inner side of the nozzle assembly hole 301, and an electric heating wire 303 is also provided on the inner side of the preheating ring 300. When the device is used, if the weather is cold, water droplets remaining at the spray head 106 are easily condensed into ice during and after the use of the equipment, thereby causing the spray head 106 to be unable to emit mist, affecting the spray effect and reducing the dust reduction effect. By installing the preheating ring 300 on the spray head 106, when the weather is cold, the electric heating wire 303 on the inner side of the preheating ring 300 can convert electrical energy into thermal energy, and the heat generated can achieve the effect of constant temperature ice melting, thereby avoiding the spray head 106 from being frozen and unable to emit mist during use, thereby improving the practicality of the device.

[0024] Specifically, the preheating ring 300 is assembled with the spray head 106 through the nozzle assembly hole 301, which is convenient for alignment installation, and an electric heating socket 304 is provided on the inner side of the preheating ring 300, the electric heating socket 304 is connected to the mica sheet 302, and the heating wire 303 is attached to one side of the mica sheet 302. At the same time, after the preheating ring 300 is installed, the mica sheet 302 is attached to the spray head 106, and the attachment can better conduct heat, so that the spray head 106 can be prevented from freezing in cold weather through preheating.
