Description

Technical Field

[0001] This utility model relates to the field of zinc powder preparation technology, and in particular to an atomized zinc powder preparation device. Background Technology

[0002] Zinc powder, as an important industrial raw material, is widely used in coatings, metallurgy, chemicals, and many other fields. In the preparation of zinc powder, atomization is a commonly used process. Its main principle is to pass molten zinc through a specific device to form droplets, then use high-pressure gas to impact and break the droplets, finally cooling them to form zinc powder.

[0003] Currently available atomized zinc powder preparation devices still have many technical limitations in practical applications, making it difficult to meet the production needs of high precision and multiple specifications:

[0004] 1. Traditional shut-off valves or single-aperture flow guiding structures are often used to control the zinc liquid delivery rate. These structures can only achieve rough flow rate adjustment and cannot accurately match parameters according to the preparation requirements of zinc powder with different particle sizes (such as fine powder requiring slow delivery with low flow rate and coarse powder requiring fast delivery with high flow rate).

[0005] 2. The atomized zinc powder often contains incompletely broken zinc blocks, impurity particles, etc. Existing filtration devices mostly use single-layer filter screens or fixed filtration structures, which have low filtration accuracy and are difficult to effectively remove fine impurities.

[0057] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0058] Reference Figure 1-6 The apparatus shown includes an atomized zinc powder preparation device, comprising:

[0059] The metal melting tank 100 is equipped with heating elements and temperature monitoring devices, which can accurately control the temperature of the zinc liquid and ensure that the zinc liquid is always in a stable molten state.

[0060] A gas injection chamber 300 is located below the metal melting chamber 100 and is used to atomize the zinc liquid transported from the metal melting chamber 100.

[0061] The conveying adjustment component 200 is used to connect the metal melting tank 100 and the gas injection tank 300, and can adjust the conveying diameter to flexibly control the conveying volume and conveying speed of the zinc liquid.

[0062] In this invention, the conveying and regulating component 200 can adopt several existing structures to regulate the zinc liquid flow rate; for example, by using a throttling valve, the diameter of the channel is controlled by rotating the throttling valve to regulate the zinc liquid flow rate.

[0063] The conveying adjustment component 200 can also adopt two overlapping plates with corresponding holes as in the prior art. The size of the holes is adjusted by the relative movement of the two plates to adjust the zinc liquid flow rate.

[0064] As can be seen from the above, the conveying adjustment component 200 can be implemented using several existing technologies, which will not be elaborated here;

[0065] The filter device 400, which is installed at the bottom of the conveying and regulating assembly 200, is used to filter the atomized zinc powder, remove impurities, and improve the purity of the zinc powder.

[0066] The working principle of this embodiment is as follows:

[0067] In use, the raw material is heated to dissolve it into liquid zinc. The liquid zinc is then conveyed to the interior of the gas injection chamber 300 via the conveying and regulating component 200. Inside the gas injection chamber 300, the zinc is broken into small droplets by the shearing force and cooling effect of the airflow and rapidly solidifies into zinc powder in the air. The solidified zinc powder falls into the interior of the filter device 400 for storage and filtration separation.

[0068] The conveying adjustment component 200 allows for flexible adjustment of the conveying diameter, thereby controlling the conveying volume and speed of the zinc liquid. Operators can precisely adjust the conveying parameters according to different production needs to meet the preparation requirements of zinc powder with different particle sizes, thus improving the applicability and production efficiency of the device.

[0069] The gas injection chamber 300 can eject high-pressure gas at a specific angle and speed to impact and break the falling molten zinc in an all-round and uniform manner, effectively improving the atomization uniformity of the molten zinc and ensuring the quality of the zinc powder.

[0070] In some embodiments of this utility model, reference is made to Figure 2 As shown, the conveying adjustment assembly 200 includes:

[0071] There are two first guide channels 210, which are respectively installed on the metal dissolution tank 100 and the gas injection tank 300. The two first guide channels 210 are used to guide and control the liquid to ensure that the metal solution after metal dissolution is delivered to the gas injection tank 300.

[0072] The regulating component 220, installed between the two first flow channels 210, adjusts the fluid flow rate and pressure according to actual needs to optimize the operating efficiency of the entire system.

[0073] In some embodiments of this utility model, reference is made to Figure 3 As shown, the adjustment component 220 includes:

[0074] The housing structure 221 serves as the supporting and protective shell for the entire assembly;

[0075] The liquid flow structure 222 is installed inside the shell structure 221 and is responsible for the flow and distribution of liquid;

[0076] The drive structure 223 is mounted on the housing structure 221 and is used to drive the liquid discharge structure 222 to adjust it, so as to precisely control and adjust the flow rate and direction of the liquid.

[0077] In this embodiment, the drive structure 223 can be implemented using various existing technologies such as linear motors, hydraulic rods, or electric push rods.

[0078] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 As shown, the shell structure 221 includes:

[0079] The square shell 2211 serves as the basic framework of the entire structure;

[0080] There are two receiving housings 2212, which are installed on the square housing 2211 and connected to the first guide channel 210 to guide and distribute fluid and ensure smooth fluid flow.

[0081] A cylindrical housing 2213 is installed at the end of the receiving housing 2212 for the installation and use of the drive structure 223.

[0082] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 As shown, the liquid-falling structure 222 includes:

[0083] The lower plate 2221 is fixedly installed inside the square shell 2211 to support the entire liquid-falling structure and ensure its stability and firmness;

[0084] The sliding plate 2222 is slidably installed inside the housing structure 221 and contacts the upper surface of the lower plate 2221. It controls the flow and distribution of liquid through sliding motion.

[0085] The material discharge channel 2223 is located on the lower plate 2221 and the sliding plate 2222, and overlaps with each other to form a continuous liquid flow channel, ensuring that the liquid can flow smoothly from one position to another.

[0086] The working principle of this embodiment is as follows:

[0087] When adjusting the overlap size of the two material dropping channels 2223, drive the drive structure 223 so that the drive structure 223 drives the sliding plate 2222 to slide relative to the lower plate 2221, thereby adjusting the overlap size between the material dropping channel 2223 on the lower plate 2221 and the material dropping channel 2223 on the sliding plate 2222.

[0088] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 As shown, the drive structure 223 includes:

[0089] The threaded sleeve 2231 is rotatably inserted into the interior of the cylindrical housing 2213. Precise adjustment and positioning can be achieved through rotation, ensuring the stability and reliability of the structure.

[0090] The threaded rod 2232 is fixedly installed at the end of the sliding plate 2222 and passes through the threaded sleeve 2231. When the threaded sleeve 2231 rotates, it drives the threaded rod 2232 to move along the threaded sleeve 2231, thereby pushing the sliding plate 2222 to perform linear movement and realize position adjustment.

[0091] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 As shown, a pointer 2233 is fixedly installed on the outer circumference of the threaded sleeve 2231, and a scale 2234 is provided at the end of the cylindrical housing 2213. The matching design of the pointer 2233 and the scale 2234 makes the adjustment of the conveying diameter more precise, further improving the ease of operation and adjustment accuracy of the device.

[0092] In some embodiments of this utility model, reference is made to Figure 2 As shown, the gas injection chamber 300 includes:

[0093] The outer casing 310 provides a closed space to ensure the efficient execution of the gas injection process;

[0094] Two high-pressure nozzles 320 are provided and installed on both sides inside the outer casing 310 and tilted downwards. The high-pressure nozzles 320 can spray gas (such as ammonia) at high speed, thereby achieving effective coverage and treatment of the target area.

[0095] The guide pipe 330 is installed at the inlet of the high-pressure nozzle 320 to guide and regulate the flow rate and direction of the gas entering the high-pressure nozzle 320, ensuring that the gas can be sprayed out evenly and stably.

[0096] In some embodiments of this utility model, reference is made to Figure 2 and Figure 6 As shown, the filter device 400 includes:

[0097] Filter housing 410 is used to house and support the entire filtration system;

[0098] Storage housing 420, which is installed at the bottom of filter housing 410, is used to collect filtered impurities or sediments;

[0099] The filter screen 430 has two parts, which are detachably installed at the upper and lower ends of the filter housing 410 for regular cleaning or replacement to ensure the filtration effect.

[0100] Pressure relief valve 440, which is installed on top of filter housing 410, is used to automatically release pressure when the internal pressure is too high, thus protecting the equipment.

[0101] In some embodiments of this utility model, reference is made to Figure 2 As shown, a second flow channel 450 is fixedly installed between the filter housing 410 and the gas injection box 300 to transport the solidified zinc powder into the interior of the filter housing 410.

[0102] The working method of this utility model:

[0103] First, metallic zinc is placed in the metal melting tank 100. The metallic zinc is heated by the heating element inside the metal melting tank 100, causing the metallic zinc to melt and form a molten zinc liquid. At the same time, the temperature monitoring device monitors the temperature of the zinc liquid in real time to ensure that the temperature of the zinc liquid is stable within the set range.

[0104] Subsequently, the molten zinc is conveyed from the metal melting tank 100 to the gas injection tank 300 via the conveying and regulating assembly 200. During the conveying process, the operator can adjust the conveying diameter according to actual production needs through the drive structure 223. Specifically, rotating the threaded sleeve 2231 causes the threaded rod 2232 to move axially due to the threaded engagement between the threaded rod 2232 and the threaded sleeve 2231, thereby causing the sliding plate 2222 to slide inside the housing structure 221. The sliding of the sliding plate 2222 changes its overlap with the material discharge channel 2223 on the lower plate 2221, thus changing the actual flow diameter of the material discharge channel 2223.

[0105] After the molten zinc enters the gas injection chamber 300, the external high-pressure gas is transported to the high-pressure nozzle 320 through the guide pipe 330. The high-pressure nozzle 320 sprays the high-pressure gas downward at a specific angle and speed to impact and break the falling molten zinc, causing the molten zinc to atomize into zinc powder particles.

[0106] The atomized zinc powder and gas mixture is conveyed to the filter device 400 through the second guide channel 450. Inside the filter device 400, the mixture first passes through the filter screen 430 at the upper end of the filter housing 410, where larger particles are filtered out; then it passes through the filter screen 430 at the lower end of the filter housing 410, where smaller particles are further filtered out. The filtered pure zinc powder falls into the storage housing 420 for collection.

[0107] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
