Technical Field

[0001] The utility model relates to the technical field of metal smelting equipment, and more particularly to an adjustable metal smelting slurry conveying device. Background Art

[0002] With the continuous advancement of global industrialization, the nonferrous and ferrous metal smelting industries are growing. The treatment of high-temperature slurries (such as aluminum slag, steel slag, and copper slag) generated during the smelting process has become a major technical challenge. During the smelting and transportation process, the slurry's high temperature, viscosity, and complex composition place high demands on the conveying equipment. Traditional slurry conveying devices often have the following problems:

[0003] 1. Unstable temperature control: Once the temperature of the slurry drops during transportation, it is prone to solidification and adhesion, leading to channel blockage or equipment shutdown. This not only affects production efficiency but also increases equipment maintenance and downtime.

[0004] 2. Difficulty in Residue Cleaning: Smelting slag often contains a variety of complex metal oxides and compounds, which adhere to the inner walls of the conveyor channel and are difficult to clean. Traditional manual cleaning methods are inefficient, and the high temperature environment poses a health risk to operators.

[0005] 3. The equipment is easily damaged: Since high-temperature slurry is corrosive and abrasive, long-term use will cause serious wear on the shaft, blades and motor of the conveying equipment, requiring frequent replacement, which increases the equipment operating costs.

[0006] 4. Incomplete spray cleaning: Many conveying devices are not equipped with automated cleaning systems. Even if there are spray equipment, the interior is often not cleaned evenly, resulting in accumulation of residues and affecting subsequent operations.

[0007] Therefore, there is a need for a conveying device that can effectively convey slurry, maintain temperature and have an automatic cleaning function. Utility Model Content

[0030] The conveying channel 1 is provided with a discharge port 101 at the lower side of one end and a feed port 102 at the upper side of the other end;

[0031] The spiral conveying mechanism includes a first motor 2, a rotating shaft 201 and a spiral conveying blade 202. The rotating shaft 201 is provided with a spiral conveying blade 202 and is connected to the power output shaft of the first motor 2.

[0032] The heating mechanism 3 surrounds the outside of the conveying channel 1 and is used to maintain the slurry within a preset temperature range;

[0033] The cleaning mechanism includes a second motor 4, a threaded screw 401, a slide rail 402 and a scraper 403. The scraper 403 slides in the chute and fits in the conveying channel 1. The threaded screw 401 is connected to the second motor 4 to drive the scraper to move along the chute.

[0034] The spray mechanism includes a water tank 5 and a plurality of high-pressure nozzles 501. The water tank 5 is arranged above the conveying channel 1. The high-pressure nozzles 501 are evenly distributed in the conveying channel 1 for cleaning the interior of the conveying channel.

[0035] Preferably, a limiting plate 103 is provided in the conveying channel 1 to prevent the scraper 403 from deviating from the chute.

[0036] Preferably, the spiral conveying blades 202 are arranged in a spiral shape along the rotating shaft 201, which can improve the conveying efficiency of the slurry.

[0037] Preferably, the first sliding seat 4031 is slidably connected to the slide rail 402 , and the second sliding seat 4032 is threadedly connected to the threaded screw 401 .

[0038] Preferably, the heating mechanism 3 adopts a structure in which electric heating surrounds the conveying channel 1 to ensure that the temperature of the slurry is stable during the conveying process.

[0039] Preferably, the high-pressure nozzle 501 is disposed on the upper side of the delivery channel 1 and is used to spray water to cover the entire interior of the channel during the cleaning process.

[0040] Preferably, the chute is arranged longitudinally along the conveying channel 1 and is consistent with the movement direction of the scraper 403.

[0041] Preferably, the water tank 5 is connected to the high-pressure nozzle 501 via a hose to facilitate adjustment of the spray flow and pressure.

[0042] Preferably, the second motor 4 is installed on one side of the conveying channel 1 and drives the scraper 403 to slide in the channel through the threaded screw 401.

[0043] Preferably, the limiting plate 103 cooperates with the scraper 403 to ensure that the scraper always fits against the inner wall of the conveying channel 1 during the cleaning process.

[0044] In actual operation, the metal smelting slurry conveying device of the utility model is widely used in various nonferrous metal and ferrous metal smelting processes to continuously convey high-temperature smelting slurry and ensure that the slurry does not solidify or become blocked during the conveying process. The following is a detailed implementation process:

[0045] 1. Equipment startup and slurry conveying operation

[0046] 1.1 Preparation:

[0047] Check whether the feed port 102 and the discharge port 101 are unobstructed, and confirm that there is no residue or blockage in the conveying channel 1.

[0048] Ensure that the spiral conveying blade 202 and the rotating shaft 201 operate smoothly, and the motor 2 is well connected and can drive the spiral conveying mechanism normally.

[0049] The heating mechanism 3 is started to preheat the conveying channel to a set temperature, such as 800-1200° C., to prevent the high-temperature slurry from cooling and adhering to the inner wall of the channel when entering.

[0050] 1.2 Slurry conveying process:

[0051] The first motor 2 is started, and the spiral conveying blade 202 rotates at high speed along the rotating shaft 201 to feed the slurry into the feed port 102 .

[0052] During the transportation process, the heating mechanism 3 works continuously to ensure that the slurry is maintained at a temperature above 800° C. to prevent it from solidifying during the transportation process.

[0053] The slurry moves along the conveying channel 1 and is finally discharged from the discharge port 101 to the subsequent processing system.

[0054] 2. Slurry temperature maintenance and heating control

[0055] During the transportation process, the heating mechanism 3 surrounds the outside of the transportation channel 1 and maintains a stable temperature by means of electric heating or pipeline steam heating.

[0056] If the temperature detection value in the channel is lower than the set threshold, the heating system will automatically increase the output to ensure that the slurry is always in a flowing state.

[0057] This heating strategy can avoid the slurry blockage problem caused by insufficient temperature in traditional conveying equipment and improve the stability of equipment operation.

[0058] 3. Automatic cleanup operations

[0059] 3.1 Start the cleanup process:

[0060] After each conveying operation is completed, the second motor 4 is started to drive the threaded screw 401 to rotate, pushing the scraper 403 to slide along the slide rail 402.

[0061] The scraper 403 fits tightly against the limiting plate 103 to ensure that it slides smoothly along the inside of the channel without deviation.

[0062] 3.2 Scraper cleaning process:

[0063] The scraper 403 starts to move from the end of the feed port 102 to push the remaining slurry toward the discharge port 101 to ensure that there is no attachment on the inner wall of the channel.

[0064] Driven by the threaded screw 401, the scraper 403 reciprocates several times until all the residues are removed.

[0065] When the scraper 403 slides, the first sliding seat 4031 cooperates with the slide rail 402, and the second sliding seat 4032 is threadedly connected to the threaded screw 401, ensuring that the scraper movement process is stable and reliable.

[0066] 4. Spray cleaning operation

[0067] 4.1 Cleaning process:

[0068] After the cleaning is completed, the high-pressure spray system in the water tank 5 is started, and the water in the water tank is sprayed into the interior of the delivery channel 1 through the high-pressure nozzle 501.

[0069] The high-pressure nozzles 501 are evenly distributed above the conveying channel to ensure that every corner can be thoroughly cleaned.

[0070] The high-pressure water flow can not only remove the residual slurry, but also cool the inside of the channel to prevent the equipment from being damaged due to long-term high-temperature operation.

[0071] 4.2 Drainage and maintenance:

[0072] After cleaning is completed, the cleaning wastewater is discharged through the discharge port 101 and is centrally recovered and processed.

[0073] The operator checks the cleaning effect to ensure that there is no residue blocking the nozzle or the conveying channel. If there is any abnormality, the spray system can be restarted for additional cleaning.

[0074] 5. Operation monitoring and maintenance

[0075] During daily use, the temperature of the conveying channel and slurry is monitored at any time through temperature sensors and equipment monitoring systems to ensure the safe operation of the equipment.

[0076] Regularly check the wear of the rotating shaft 201, blades 202, scrapers 403 and motors (2, 4) of the spiral conveying mechanism, and perform necessary maintenance and replacement.

[0077] Maintain the high-pressure nozzle 501 and the water tank 5 weekly to ensure that the nozzle is unobstructed and there is no sediment in the water tank.

[0078] 6. Application Examples and Effects

[0079] In a test at a non-ferrous metal smelting plant, the conveying device successfully transported 200 tons of high-temperature aluminum slag, with the slag slurry temperature always maintained above 850°C and no blockage occurred.

[0080] The automatic cleaning system runs after each conveying to ensure that there is no residue inside the equipment, avoiding the trouble of frequent shutdown and cleaning of traditional conveying equipment.

[0081] The high-pressure spray system greatly improves the cleaning efficiency of the equipment and reduces maintenance time and labor costs.

[0082] In summary, the adjustable metal smelting slurry conveying device of this utility model achieves efficient slurry conveying, temperature maintenance, and automatic cleaning through the combination of spiral conveying, automatic cleaning, and high-pressure spraying systems, thereby improving the operational stability and reliability of the device. This device has broad application prospects in the fields of nonferrous and ferrous metal smelting, effectively reducing production costs and improving smelting efficiency.
