[0021] Embodiment:
[0022] Please refer to Figures 1-6 , the present utility model provides a technical solution: an agitator metal removal device applicable to oil and gas drilling and production, including an agitator tank body 1; a feeding component 2, the bottom of the feeding component 2 is fixedly connected to the top of the agitator tank body 1, and the feeding component 2 is used for feeding mud; a feeding hopper 3, the bottom of the feeding hopper 3 is fixedly connected to the top of the feeding component 2; a separation component 4, the outside of the separation component 4 is rotatably connected to the inside of the feeding component 2, and the separation component 4 is used for separating metal from mud; a collection component 5, the outside of the collection component 5 is fixedly connected to both sides of the feeding component 2, and the collection component 5 is used for collecting metal. When in use, the mud is fed into the inside of the feeding hopper 3, and the mud flows into the inside of the feeding component 2 along the feeding hopper 3. After the mud is processed by the separation component 4, it moves downward into the inside of the agitator tank body 1, and the metal in the mud is collected by the collection component 5. By setting the separation component 4, the metal impurities in the mud are separated to prevent metal impurities from entering the inside of the agitator tank body 1. By setting the collection component 5, the metal impurities in the mud are collected, facilitating subsequent treatment of the metal impurities.
[0023] The feeding assembly 2 includes a housing 21. The top of the housing 21 is fixedly connected to the bottom of the feeding hopper 3, and the bottom of the housing 21 is fixedly connected to the top of the agitator tank body 1. A guiding plate 23 is fixedly connected to the inner side of the housing 21, and a sieve plate 22 is fixedly connected to the top inside the housing 21. During use, the slurry is fed into the interior of the feeding hopper 3. The slurry enters the interior of the feeding assembly 2 along the feeding hopper 3. The slurry falls onto the sieve plate 22. The sieve plate 22 intercepts the impurities with larger volume in the slurry, and the remaining slurry moves downward along the housing 21 onto the guiding plate 23, and then moves downward along the guiding plate 23 onto the separation assembly 4. By providing the feeding assembly 2, large impurities in the slurry are intercepted, preventing larger and harder impurities from entering the agitator and affecting the agitation of the agitator.
[0024] The collection assembly 5 includes a collection housing 51. The outer side of the collection housing 51 is fixedly connected to both sides of the housing 21. A scraping component 52 is fixedly connected to the top inside the cavity of the collection housing 51. A collection bin 53 is slidably connected to the bottom inside the cavity of the collection housing 51. During use, the separation assembly 4 drives the metal impurities to move into the interior of the collection assembly 5. The scraping component 52 scrapes off the metal impurities on the separation assembly 4, and the metal impurities fall downward along the collection housing 51 into the interior of the collection bin 53. By providing the collection assembly 5, the metal impurities in the slurry are collected, facilitating subsequent treatment of the metal impurities.
[0025] The scraping component 52 includes a fixing plate 521. The outer side of the fixing plate 521 is fixedly connected to the top inside the cavity of the collection housing 51. A blower 522 is fixedly installed on the top of the fixing plate 521. The bottom of the blower 522 penetrates through the fixing plate 521 and is fixedly connected to an air outlet pipe 523. During use, the blower 522 in the scraping component 52 is started, and the blower 522 drives the air flow. The air flow flows out along the air outlet pipe 523, blowing the impurities adhered to the scraper 525 to reduce the impurities adhered to the scraper 525.
[0026] The bottom of the fixed plate 521 is rotatably connected to a rotating plate 524. The outer side of the rotating plate 524 is fixedly connected to a scraping plate 525. The outer side of the scraping plate 525 is fixedly connected to an elastic plate 526. The top of the elastic plate 526 is fixedly connected to the bottom of the fixed plate 521. During use, the bottom of the scraping plate 525 contacts the surface of the separation component 4, scraping off the metal impurities adsorbed on the surface of the separation component 4. The metal impurities fall downward along the collection shell 51 into the collection bin 53. When the resistance received by the scraping plate 525 is too large, the scraping plate 525 rotates under the force. The scraping plate 525 drives the rotating plate 524 to rotate along the fixed plate 521, and the scraping plate 525 drives the elastic plate 526 to bend and deform. After the resistance received by the scraping plate 525 decreases, the elastic plate 526 drives the scraping plate 525 to reset. During scraping, air blows on the scraping plate 525 to prevent residual mud from adhering to the scraping plate 525. By providing the scraping component 52, the metal impurities on the separation component 4 are scraped, preventing the metal impurities from being continuously adsorbed on the separation component 4 and reducing the working burden of the separation component 4.
[0027] The separation component 4 includes a driving roller 41. The two sides of the driving roller 41 are rotatably connected to the inner side of the collection shell 51.

The two sides of the rotating roller 43 are rotatably connected to the two sides of the outer shell 21. The outer side of the conveyor belt 42 is fixedly connected to an electromagnet 44. During use, the driving roller 41 in the separation component 4 is connected to an external motor. The motor drives the driving roller 41 to rotate. The driving roller 41 drives the conveyor belt 42 to move. The conveyor belt 42 drives the rotating roller 43 to move. At the same time, the electromagnet 44 on the conveyor belt 42 is energized. When the mud falls on the separation component 4, the separation component 4 drives the mud to move towards the middle of the outer shell 21. The electromagnet 44 adsorbs the metal impurities in the mud. When the conveyor belt 42 moves to the lower part, the mud falls downward into the stirring tank body 1. The metal impurities in the mud are attracted by the electromagnet 44 and will not fall downward due to gravity. The electromagnet 44 drives the metal impurities to move into the collection component 5. By providing the separation component 4, the metal impurities in the mud are processed, preventing the metal impurities from entering the stirring tank body 1 and preventing the metal impurities from damaging the blades of the stirrer.
[0028] Working principle:
[0029] During use, the mud is fed into the feed hopper 3. The mud enters the feed component 2 along the feed hopper 3. The mud falls on the sieve plate 22. The sieve plate 22 intercepts the impurities with larger volume in the mud. The remaining mud moves downward along the outer shell 21 to the guide plate 23, and then moves downward along the guide plate 23 to the separation component 4.
[0030] In the separation component 4, the driving roller 41 is connected to an external motor. The motor drives the driving roller 41 to rotate, the driving roller 41 drives the conveyor belt 42 to move, and the conveyor belt 42 drives the rotating roller 43 to move. At the same time, the electromagnet 44 on the conveyor belt 42 is energized. When the mud falls on the separation component 4, the separation component 4 drives the mud to move towards the middle of the housing 21. The electromagnet 44 adsorbs the metal impurities in the mud. When the conveyor belt 42 moves to the lower part, the mud drops down into the inside of the agitator tank 1. The metal impurities in the mud are attracted by the electromagnet 44 and will not fall down due to gravity. The electromagnet 44 drives the metal impurities to move into the collection component 5;
[0031] The bottom of the scraper 525 touches the surface of the separation component 4, and scrapes off the metal impurities adsorbed on the surface of the separation component 4. The metal impurities fall down along the collection shell 51 into the inside of the collection bin 53. When the resistance received by the scraper 525 is too large, the scraper 525 rotates under the force, the scraper 525 drives the rotating plate 524 to rotate along the fixed plate 521, and the scraper 525 drives the elastic plate 526 to bend and deform. After the resistance received by the scraper 525 decreases, the elastic plate 526 drives the scraper 525 to reset. At the same time, the fan 522 in the scraping component 52 starts, the fan 522 drives the air flow to flow, the air flow flows out along the air outlet pipe 523, and the air flow blows towards the scraper 525 to prevent the remaining impurities from adhering to the scraper 525.
