Description

Technical Field

[0001] This utility model relates to the field of centrifuge equipment technology, specifically to a bidirectional cleaning device for the inner and outer walls of a centrifuge drum. Background Technology

[0002] Centrifuges are widely used as key separation equipment in solid-liquid separation processes across various industries, including chemical, pharmaceutical, food, and environmental protection. With the expansion of production scale and increasing efficiency requirements, centrifuges inevitably accumulate dirt on the inner wall of their drums during continuous operation. This residue not only affects the centrifuge's separation efficiency but may also adversely impact the quality of subsequent products. Traditionally, cleaning residual dirt from centrifuge drums relies primarily on manual operation. This method is not only labor-intensive and inefficient but also poses safety risks; improper operation may result in personal injury or equipment damage.

[0003] Furthermore, while existing automated cleaning equipment can alleviate the burden on manual labor to some extent, most suffer from problems such as complex design, high cost, and uneven cleaning results. In particular, traditional cleaning methods often fail to completely remove stubborn stains and residues in small crevices, leading to shorter cleaning cycles and increased maintenance costs. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a bidirectional cleaning device for the inner and outer walls of a centrifuge drum. The device includes a base with a vertical beam fixed to it. The inner wall of the vertical beam is fixed with a platform for placing the centrifuge drum. The outer wall of the vertical beam has an opening and closing door for inserting the centrifuge drum. Two platforms are provided, one in front and one behind, with a gap between them. A bidirectional ball screw is rotatably connected to the side wall of the vertical beam. An air jet platform and a water jet platform are connected to the outer side of the bidirectional ball screw. Multiple air nozzles are installed at the bottom of the air jet platform, each connected to an air delivery pipe. The other end of the air delivery pipe is connected to an air compressor. Multiple water nozzles are installed at the bottom of the water jet platform, each connected to a water delivery pipe. The other end of the water delivery pipe is connected to a water pump. A servo motor is located on the side of the platform. The output end of the servo motor is connected to a rotating rod extending above the platform. A scraper is fixed to the outer side of the rotating rod.

[0005] Furthermore, the top of the shelf, the bidirectional ball screw, and the rotating rod are all tilted at the same angle.

[0006] Furthermore, a top seat is fixed to the side wall of the upright beam, and the air jet sliding platform and water jet sliding platform are slidably connected to the bottom of the top seat.

[0007] Furthermore, a motor mounting bracket is fixed to the bottom of the top mount, and the servo motor is mounted on the motor mounting bracket.

[0008] Furthermore, sprockets are fixed to the outer surfaces of both the bidirectional ball screw and the rotating rod, and the two sprockets are connected by a wound chain.

[0009] Furthermore, a storage box is placed on top of the base below the shelf.

[0010] The beneficial effects of this utility model are as follows: It achieves continuous and efficient cleaning of the inner and outer walls of the centrifuge drum through automation, integrating multiple functions such as scraper cleaning, air jet flushing and water spray cleaning, and realizes thorough cleaning of the inner and outer walls of the centrifuge drum, especially effective against stubborn stains; it effectively shortens the cleaning cycle, improves production efficiency, and reduces manual operation.

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] A bidirectional cleaning device for the inner and outer walls of a centrifuge drum, such as... Figure 1 and Figure 2 As shown, the system includes a base 1, on which a vertical beam 2 is fixed. The inner wall of the vertical beam 2 is fixed with a platform 3 for placing a centrifuge drum 18. The outer wall of the vertical beam 2 is equipped with an opening and closing door 4 for placing the centrifuge drum 18. There are two platforms 3, one in front and one behind, with a gap between them. A storage box 17 is placed on the top of the base 1 below the platform 3. A bidirectional ball screw 5 is rotatably connected to the side wall of the vertical beam 2. The outer side of the bidirectional ball screw 5 is connected to an air jet slide 6 and a water jet slide 7. Multiple air nozzles 8 are installed at the bottom of the air jet slide 6. The air nozzles 8 are connected to air delivery pipes. The other end of the air delivery pipes is connected to an air compressor 10. Multiple water nozzles 9 are installed at the bottom of the water jet slide 7. The water nozzles 9 are connected to water delivery pipes. The other end of the water delivery pipes is connected to a water pump.

[0018] like Figure 1 and Figure 2 As shown, in this embodiment, a servo motor 11 is provided on the side of the platform 3. The output end of the servo motor 11 is connected to a rotating rod 12 extending above the platform 3. A scraper 13 is fixed on the outer side of the rotating rod 12. A top seat 14 is fixed on the side wall of the upright beam 2. The air jet sliding platform 6 and the water jet sliding platform 7 are slidably connected to the bottom of the top seat 14. A motor mounting bracket 15 is fixed on the bottom of the top seat 14. The servo motor 11 is mounted on the motor mounting bracket 15. A sprocket is fixed on the outer side of both the bidirectional ball screw 5 and the rotating rod 12. The two sprockets are connected by a winding chain 16.

[0019] like Figure 1 As shown, in this embodiment, the top of the platform 3, the bidirectional ball screw 5, and the rotating rod 12 are inclined at the same angle.

[0020] The working principle of this utility model is as follows:

[0021] By opening the door 4, the centrifuge drum 18 to be cleaned is pushed onto the platform 3 through the door 4, so that the rotating rod 12 and the scraper 13 are inside the centrifuge drum 18. The servo motor 11 is started to drive the rotating rod 12 to rotate, which in turn drives the scraper 13 to rotate. During the rotation of the scraper 13, the inner wall of the centrifuge drum 18 is cleaned, and the residual dirt on the inner wall of the centrifuge drum 18 is scraped off.

[0022] During the rotation of the rotating rod 12, the chain 16 drives the bidirectional ball screw 5 to rotate, which in turn drives the air jet slide table 6 and the water jet slide table 7 to move along the axial direction of the bidirectional ball screw 5. The air compressor 10 and the water pump are started, pumping air and water to the air jet nozzle 8 and the water jet nozzle 9 respectively. The water jet nozzle 9 sprays water onto the centrifuge drum 18 as it slides with the water jet slide table 7 to clean the centrifuge drum 18 and soften stubborn stains. The air jet nozzle 8 sprays air onto the centrifuge drum 18 as it slides with the air jet slide table 6, dispersing the sewage and spraying the stubborn stains off the outer surface of the centrifuge drum 18. Sewage and residue fall through the filter holes of the centrifuge drum. Due to the inclined setting of the platform 3, sewage and residue can also flow out of the centrifuge drum 18 along the inclined surface. Sewage and residue finally fall into the waste box 17.

[0023] 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 claimed utility model.
