Description

Technical Field

[0001] This utility model relates to the field of self-cleaning mixing technology, and in particular to a self-cleaning mixer. Background Technology

[0002] A mixer is a machine that uses a bladed shaft to rotate within a cylinder or trough, mixing various raw materials to create a mixture or a suitable consistency. Mixers come in various sizes, from large concrete mixers to small kitchen food mixers. Smaller mixers are mostly vertical, meaning the rotating shaft is set vertically. After use, mixers require cleaning, usually by hand washing or high-pressure water rinsing, making cleaning relatively troublesome.

[0003] Chinese patent application number CN218222247U discloses a self-cleaning mixer. This design uses a limiting component to select whether the mixing rod is clamped or not. When the mixing rod is clamped, it remains tilted, and the motor drives the rotating shaft to rotate, which in turn drives the mixing rod to perform normal mixing. When cleaning is required, clean water is injected into the mixing tank, and then the clamping of the mixing rod is released. Subsequently, the motor starts, and under the action of centrifugal force, the mixing rod enters a horizontal state, and the brush plate contacts the inner wall of the mixing tank. At the same time, the telescopic device continuously extends and retracts, allowing the brush plate to move up and down while rotating, thereby completing a thorough cleaning of the inner wall of the mixing tank. After cleaning, the valve is opened to discharge the wastewater, thus achieving self-cleaning. However, when mixing viscous materials in the mixing tank, the inner wall is difficult to clean, and the overall utilization rate is low due to the use of separate cleaning parts.

[0004] Therefore, we propose a self-cleaning mixer. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a self-cleaning mixer. Through the spiral stirring blade, stirring scraper, and stirring cutter, the water in the cleaning tank is driven from bottom to top by the spiral stirring blade, which prevents impurities in the tank from settling to the bottom and causing residue on the inner wall. At the same time, it can also turn the bottom material up during stirring.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A self-cleaning mixer includes a mixing tank assembly, the mixing tank assembly including a vessel body, a discharge pipe fixedly connected to the bottom end of the vessel body, a feed pipe fixedly connected to the middle part of the vessel body, a solenoid valve fixedly connected to the bottom end of the discharge pipe, and multiple feed ports arranged in a ring at equal intervals at the outer end of the vessel body, the feed ports penetrating the inner wall of the vessel body and communicating with the interior of the vessel body.

[0008] The support assembly includes multiple anti-wear agent filling cylinders and a damping shaft arranged in a ring at equal intervals. The anti-wear agent filling cylinders are installed outside the reactor body, with their outer ends located outside the feed inlet. The outer end of the anti-wear agent filling cylinder has a discharge port that penetrates the inner wall of the anti-wear agent filling cylinder and communicates with both the cylinder and the feed inlet. The damping shaft is installed inside the feed inlet and is rotatably connected to it. The outer end of the damping shaft is fixedly connected to multiple material-pushing blades arranged in a ring. Each material-pushing blade penetrates both the feed inlet and the discharge port and is adapted to fit the feed inlet and the discharge port.

[0009] A stirring assembly includes a top cover, an internal toothed ring fixedly connected to the bottom end of the top cover, a motor fixedly connected to the inner end of the top cover, a drive shaft fixedly connected to the output end of the motor, the drive shaft extending into the interior of the vessel body, and an arc-shaped stirring blade fixedly connected to the bottom end of the drive shaft, the arc-shaped stirring blade being adapted to the bottom end of the interior of the vessel body.

[0010] Furthermore, a bearing is provided in the middle of the drive shaft, the inner ring of the bearing is fixedly connected to the drive shaft, and a tripod is fixedly connected to the outer ring of the bearing. Each leg of the tripod is rotatably connected to a vertical shaft, a stirring shaft, and a connecting shaft at the end away from the bearing. The vertical shaft, stirring shaft, and connecting shaft all extend into the interior of the vessel body. A driven gear is fixedly connected to the upper end of the middle of the vertical shaft, stirring shaft, and connecting shaft. The driven gear meshes with an internal gear ring.

[0011] Furthermore, a transmission gear is fixedly connected to the middle of the transmission shaft, the transmission gear is located at the bottom end of the tripod, and the transmission gear meshes with the driven gear.

[0016] Furthermore, a sealing cap is detachably connected to the top of the anti-wear agent filling cylinder.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This solution uses spiral stirring blades, stirring scrapers, and stirring cutters. The spiral stirring blades transport water in the cleaning tank from bottom to top, preventing impurities in the tank from settling to the bottom and leaving residue on the inner wall. At the same time, the stirring process also helps to turn the bottom material up.

[0019] 2. This solution uses a scraper to scrape the inner wall of the mixing tank during cleaning, preventing the material from sticking to the inner wall and causing incomplete cleaning. It can also scrape the inner wall during the mixing process. Attached Figure Description
