Description

Technical Field

[0001] This utility model relates to the technical field of colloid mill equipment, and in particular to an anti-clogging colloid mill equipment for petroleum extraction. Background Technology

[0002] Colloid mills are primarily used in the food and chemical industries for grinding materials such as dairy products, chocolate, pigments, and lubricating oils to achieve better mixing, emulsification, and homogenization. With the continuous development of the petroleum industry, higher demands are being placed on material handling during oil extraction. Some oil-containing materials involved in oil extraction, such as crude oil and oil sands, require fine grinding to improve the efficiency and quality of subsequent processing. Traditional colloid mills, when applied to oil extraction, have encountered problems such as material blockage and insufficient grinding. To solve these problems, researchers and engineers have developed and designed this anti-blocking colloid mill for oil extraction, based on the characteristics of the materials extracted. By adding an anti-blocking structure and optimizing the stirring and grinding components, it is better suited to the material handling needs of the oil extraction field.

[0003] However, traditional equipment has a relatively simple and singular internal mixing structure, which cannot fully and evenly mix the materials. This makes the materials prone to clumping in key parts such as the grinding chamber. Moreover, during the material conveying process, there is a lack of a powerful auxiliary pushing structure, which prevents the materials from flowing smoothly inside the equipment. This not only increases the risk of material blockage, but also causes insufficient grinding and inconsistent product quality, which needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0005] This utility model adopts the following technical solution: A colloid mill device for petroleum extraction with anti-clogging properties, including a fixed base, a support seat fixedly installed at the top of the fixed base, a colloid mill assembly fixedly installed at the top of the support seat, a feed hopper fixedly installed at the top of the colloid mill assembly, a discharge pipe fixedly installed at the side end of the colloid mill assembly, a return pipe fixedly installed at the top of the discharge pipe, a valve fixedly installed on the surface of the discharge pipe, a motor fixedly installed on the top surface of the fixed base, a gear one fixedly installed at the output end of the motor, a gear two sleeved inside the fixed base, a rotating rod fixedly installed at the top of the gear two, a pulley one fixedly installed at the bottom end of the gear two, a pulley two sleeved inside the fixed base, a belt one sleeved on the outer surface of the pulley one and pulley two, and a valve fixedly installed at the top of the pulley two.

The surface of 42 comes into contact with the spherical pull block 42. The movement of the spherical pull block 42 causes the fixed rod 38 to move. Then, the movement of the fixed rod 38 causes the limiting plate 39 to move. Subsequently, the movement of the fixed rod 38 causes the spring 40 to retract.

Then, by moving the limiting block 25, the rotating rod 22 and limiting block 32 are disengaged from the limiting groove 26 and limiting groove 28. Then, the hand contacts the surface of the rotating block 33 and rotates the rotating block 33. The rotation of the rotating block 33 drives the rotating column 17 to rotate. Then, the rotation of the rotating column 17 drives the torsion spring 18 to contract. Then, the rotation of the rotating column 17 drives the rotating plate 21 to rotate. Then, the rotation of the rotating plate 21 drives the pulley 23, rotating rod 22 and belt to rotate. Then, the hand contacts the surface of the spherical pull block 42 and pulls the spherical pull block 42. The spherical pull block 42 moves... The fixed rod 38 is moved by the movement of the fixed rod 38, which in turn moves the limiting plate 39. Then, the fixed rod 38 moves and causes the spring 40 to retract. The fixed rod 38 then disengages from the fixed groove 41. The hand then contacts the surface of the filter cylinder 34 and pulls it. The movement of the filter cylinder 34 causes the rotating rod 27, stirring blade 29, rotating rod 30, and stirring block 31 to move. The filter cylinder 34 can then be disengaged from the feed hopper 4. Rotating the rotating rod 27 will then disengage the rotating rod 27 and rotating rod 30. The stirring blade 29, stirring block 31, and filter cylinder 34 can then be cleaned.
