Description

Technical Field

[0001] The present application relates to the field of water atomization powder making, and in particular to a water atomization powder making device. Background Art

[0002] Water atomization powder making equipment is an advanced process equipment that uses high-pressure water to spray molten metal through an annular spray disc, and forms metal powder through impact and tearing. However, when high-pressure water sprays the dripping molten metal, the impacted molten metal forms a number of tiny droplets, which quickly solidify into powder in the air, and a large number of flying droplets will fly out in all directions. It is difficult to avoid that some of the droplets fly upward and adhere to the opening of the channel for the molten metal to enter. After cooling, it becomes metal. After working for a long time, a large amount of metal powder accumulates, which can easily lead to blockage of the channel opening. Summary of the invention

[0003] In order to improve the problem of metal powder accumulation and clogging of channels, the present application provides a water atomization powder making device.

[0004] The present application provides a water atomization powder making device, which adopts the following technical solution:

[0006] By adopting the above technical scheme, the metal powder on the inner wall near the channel opening is cleaned by a cleaning mechanism. The metal powder is formed by metal droplets that remain in a high-temperature molten state and splash onto the inner wall of the channel, and then cool and solidify. However, the distance from the metal droplets to the inner wall of the channel is too large, and the metal droplets will solidify and cool before flying to the inner wall of the channel. At this time, they will not adhere to the inner wall of the channel. Since the channel opening is close to the distance where the metal droplets are impacted by water mist, there is a possibility that the metal droplets adhere before solidification. Therefore, this problem only exists on the inner wall near the channel opening. After cleaning by the cleaning mechanism, the diameter of the channel opening for the metal droplets to fall can be guaranteed, thereby ensuring the processing efficiency.

[0007] Optionally, the cleaning mechanism includes a scraping ring that is lifted and slid on the inner wall of the channel, and the scraping ring is used to scrape off metal powder adhered to the inner wall of the channel.

[0008] By adopting the above technical solution, the scraping ring slides to scrape off the metal powder on the inner wall of the channel, and the metal powder blocking the channel opening is ejected, which is convenient, fast and efficient.

[0014] By adopting the above technical solution, the lifting drive member rotates the rotating shaft to drive the screw to rotate, the lifting slot limits the rotation of the lifting block, and the rotation of the screw drives the lifting block to lift and slide, and the connecting hook allows the scraper ring to be positioned lower than the lifting block, so that the lifting block does not need to be moved to the lowest end, and the scraper ring can slide out from the opening of the channel to push out the adhered metal powder, thereby realizing automation, convenience, speed and higher efficiency.

The temperature detection component is used to detect the temperature in the channel, and a temperature detection signal is obtained and output to the data processing module. The data processing module calculates and processes the temperature detection signal to obtain a processing signal and outputs it to the lifting drive component to realize automatic lifting and scraping of the scraper ring.

[0018] By adopting the above technical solution, the temperature can be automatically detected, and it can be automatically calculated to determine whether the metal powder adhering around the channel opening is sufficient, so that it can be automatically scraped off, which is convenient and fast and improves automation.

The copper cup 111 and the nozzle 112 are connected to the upper inner wall of the cover body 114. An opening communicating with the inside of the nozzle 112 is opened at the upper end of the cover body 114. The copper cup 111 is penetrated from top to bottom and a channel 12 for metal liquid to enter is opened. The copper cup 111 is embedded in the upper end of the atomization barrel 1. The nozzle 112 is installed on the upper end of the inner wall of the copper cup 111. The opening diameter of the nozzle 112 is much smaller than the opening diameter of the copper cup 111. The metal liquid flows downward into the copper cup 111 after the flow is limited by the nozzle 112, and continues to flow down in the copper cup 111 into the atomization barrel 1. An atomizing mechanism 2 for spraying atomization is installed in the atomizing barrel 1. The atomizing mechanism 2 at least includes an atomizing nozzle 21 for spraying atomized water and a water supply part for supplying water to the atomizing nozzle. The atomizing nozzle 21 is hinged on the inner wall of the atomizing barrel 1 or the inner wall of the copper cup 111. There are multiple atomizing nozzles 21.

[0056] Reference Figure 3 The cleaning mechanism 3 includes a scraper ring 31 that is lifted and slid on the inner wall of the channel 12. The outer ring side wall of the scraper ring 31 is in contact with the inner wall of the channel 12. The scraper ring 31 is used to scrape off the metal powder adhering to the inner wall of the channel 12. Three tie rods 32 are fixedly connected to the upper end surface of the scraper ring 31.

[0057] The implementation principle of a water atomization powder making device in Example 1 of the present application is as follows: when powder making is being carried out, molten metal liquid flows into the copper cup 111 from the nozzle 112, and then high-pressure water mist is sprayed onto the metal liquid flowing out from the opening at the lower end of the copper cup 111 through the atomizing nozzle 21, so as to impact the metal liquid into tiny metal droplets, and the scattered metal droplets will adhere to the lower end of the copper cup 111. The staff can first remove the thermal insulation cover 36, and then pull the pin 35 out of the limiting hole 34, and then control the pull rod 32 to press down, so that the scraper ring 31 slides out from the lower end of the copper cup 111 to scrape off the metal solidified on the copper cup 111.

The screw rod 42 passes through the lifting block 43, and the lifting block 43 is threadedly connected to the screw rod 42. The cover body 114 is provided with a heat-insulating cap 44 for covering and wrapping the lifting drive member 4 for insulation. The heat-insulating cap 44 is fixed to the upper end surface of the cover body 114 by a bolt thread connection.

[0059] Reference Figure 5 With stickers Figure 6 A plurality of make way grooves 5 are provided on the inner wall of the lifting groove 41. The plurality of make way grooves 5 are distributed on the inner walls of the four sides of the lifting groove 41, and adjacent make way grooves 5 are connected to each other. Sealing pieces 51 are fixedly connected to the upper and lower end surfaces of the lifting block 43. The sealing pieces 51 are inserted into the make way grooves 5. The sealing pieces 51 close the opening of the lifting groove 41. The sealing pieces 51 slide in the lifting groove 41 along with the displacement of the lifting block 43.

[0060] Reference Figure 5 and Figure 7, and also includes a data processing module 14 for data processing. The data processing module 14 includes a processor and a database. The database is used to store various threshold data, such as temperature rise threshold, temperature drop threshold, spray position data, natural temperature drop threshold in the barrel, channel length threshold, metal material threshold, thermal conductivity, heat dissipation coefficient in the barrel, etc. A plurality of temperature detection components 15 are installed in the channel 12.

The temperature detection element 15 is used to detect the temperature in the channel 12, and obtain a temperature detection signal and output it to the processor. After receiving the temperature detection signal, the processor calls the corresponding threshold data from the database, calculates and processes it, and obtains a processing signal and outputs it to the lifting drive element 4 to realize automatic lifting and scraping of the scraper ring 31.

[0061] The processor may include a central processing unit such as a CPU or MPU or a host system built around a CPU or MPU, including hardware or software.

With the development of integrated circuit technology, some protocols that belong to the external bus (E-Bus) protocol are also classified as internal protocols after the external bus (E-Bus) is integrated into the chip.

[0062] Example 2 of the present application discloses a method for cleaning a water atomization powder making device. Figure 8 The cleaning method of water atomization powder making equipment includes the following steps:

[0063] S1, obtain temperature detection signal and time data;

[0064] S11, determining temperature rise data through temperature detection signal and time data;

[0065] S12. Determine a processing signal based on the temperature rise data and a preset temperature rise threshold value and output it.

[0066] In detail: if the time data is the 1st second, if the temperature detection signal is 100℃, if the time data is the 2nd second, if the temperature detection signal is 150℃, if the time data is the 3rd second, if the temperature detection signal is 120℃, then the temperature rise data can be obtained as 50℃ / s and -30℃ / s respectively. Assuming the temperature rise threshold is 60℃ / s and -50℃ / s, it means that the actual temperature rises too slowly and the temperature drops too slowly. It may be that thicker metal is adhered to the position detected by the temperature detection component 15, thereby affecting the heat conduction. At this time, the corresponding processing signal is output to make the lifting drive component 4 work, and the scraping ring 31 is lowered to scrape off the metal adhered to the surrounding opening surface of the lower end of the copper cup 111.

[0067] Reference Fig. 9 and Fig.10 , further comprising the following steps:

[0068] S2, obtaining spray data, obtaining water pressure data, and temperature detection signals including actual inlet temperature data and actual adhesion temperature data;

[0069] S21, determining theoretical cooling speed data through spray data, water pressure data and a preset cooling threshold;

[0070] S22, determining adhesion temperature change rate data through adhesion temperature data and time data;

[0071] S23, determining spray adhesion distance data through spray data and preset spray position data;

[0072] S24, determining theoretical adhesion temperature data through the inlet temperature data, the preset channel length threshold, the preset natural temperature drop threshold in the barrel, the theoretical temperature drop rate data and the spray adhesion data;

[0073] S25, determining the adhesion temperature difference value by using the theoretical adhesion temperature data and the actual adhesion temperature data;

[0074] S26, determining first adhesion data according to the adhesion temperature difference, a preset metal material threshold and a preset thermal conductivity coefficient;

[0075] S27, determining second adhesion data based on actual temperature adhesion data, adhesion temperature change rate data, metal material threshold and preset barrel heat dissipation coefficient;

[0076] S28, determining a processing signal based on the first adhesion data, the second adhesion data and a preset thickness threshold, and outputting the processed signal.

[0077] In detail: the spray data is the atomization degree and direction of the atomizing nozzle 21, the water pressure data is the pressure of the sprayed water mist, the speed of the molten metal entering the nozzle 112 is fixed, which can be directly substituted into the calculation, the actual inlet temperature data is the temperature of the molten metal in the lower end portion where the nozzle 112 is connected to the inside of the copper cup 111, the actual adhesion temperature data is the temperature around the opening surface of the lower end portion of the copper cup 111, the cooling threshold is the current atomization degree and the direction of the atomizing nozzle 21, combined with the current water pressure, the impact force caused when contacting the metal droplets and the contact area of ​​the water are obtained, and thus the speed at which the splashing metal droplets are cooled is the theoretical cooling speed number. The actual detected adhesion temperature data is combined with the time data to obtain the temperature change at the lower end of the copper cup 111, including the temperature rise caused by the metal droplets flying onto the copper cup 111 and the temperature drop over time, which is the adhesion temperature change rate data; the spray position data is the distance between the atomizing nozzle 21 and the position where the metal droplets flow down, and the direction of the atomizing nozzle 21 in the spray data. The distance required for the metal droplets directly sprayed by the atomizing nozzle 21 to splash to the lower end of the copper cup 111 can be calculated. For example, if the spray position data is 20 cm, and the angle between the direction angle of the atomizing nozzle 21 and the horizontal direction is 30°, the spray adhesion distance data can be obtained as follows: When the molten metal flows in, the inlet temperature data is the temperature at the time of inflow, the channel length threshold is the length of the copper cup 111 that the molten metal needs to pass through after flowing in, and combined with the spray adhesion distance data, the distance traveled by the molten metal from the inflow to the position directly exposed to the atomizing nozzle 21 can be obtained, and then combined with the natural temperature drop threshold in the barrel, it can be obtained how much the molten metal will cool down after flowing through this distance, and the inlet temperature data minus the cooling data can be used to obtain the temperature of the molten metal before being directly exposed to the atomizing nozzle 21. The theoretical cooling rate data combined with the spray adhesion distance data can be used to obtain the temperature that the molten metal will lower during splashing. After being directly exposed to the atomizing nozzle 21, the theoretical temperature to the copper cup 111 can be obtained by subtracting the temperature that will be lowered during the splashing process from the temperature before being directly exposed, and finally obtaining the temperature that should be detected in theory. This is the theoretical adhesion temperature data, and the difference between the theoretical adhesion temperature data and the actual adhesion temperature data is the influence, which is the adhesion temperature difference. The material of the molten metal is different. It will lead to different thermal conductivity coefficients. For example, if the metal liquid is silver, the thermal conductivity coefficient is 429, and the adhesion temperature difference combined with the thermal conductivity coefficient can be used to obtain how thick the splashing metal droplets have to pass through before the heat is transferred to the temperature detection component 15, which is the first adhesion data; and when cooling, different metal materials will correspond to different cooling speeds. The heat dissipation coefficient in the barrel is the temperature in the reference barrel when it is working. If the metal material threshold is a, the material will cool down by 1° per second for every 10° difference in thickness from the external environment, and the heat dissipation coefficient in the barrel is 80°, then the difference between the current actual adhesion temperature data and the environment can be obtained by combining it, and then the theoretical cooling speed can be obtained by combining it with the metal material threshold, but there is a difference with the actual adhesion temperature change speed data, and this difference and the metal material threshold can be used to calculate how much thickness of metal there is that affects the heat dissipation, and this thickness is the second adhesion data, and then the first adhesion data is compared with the second adhesion data, and the median is taken for comparison with the thickness threshold to obtain the corresponding processing signal and output it.

[0078] Embodiment 2 of the present application discloses a computer-readable storage medium. The computer-readable storage medium stores a computer program that can be loaded by a processor and execute a method for cleaning a water atomization powder making device.
