Description

Technical Field

[0001] This invention belongs to the field of engineering equipment technology, and specifically relates to a continuous mixer without a shared base. Background Technology

[0002] Currently, twin-shaft continuous mixers are widely used in mineral processing, chemical industry, coal washing, wastewater treatment, and tailings treatment. However, existing continuous mixers have the following problems:

[0003] 1. The power system and mixing tank share a single machining base. The mounting surfaces on the base require machining, and the base's considerable length makes machining difficult and time-consuming. The shared base is also long and has low rigidity, making it highly susceptible to deformation during hoisting and transportation. The overall length of the machine requires a larger factory to accommodate it, significantly increasing project investment costs.

[0004] 2. The power transmission of the mixer drive system usually adopts the method of motor → coupling A → gearbox → coupling B → synchronous gearbox → coupling C → mixing shaft. The multi-coupling structure greatly increases the length of the mixer in the axial direction, and the length of the power system even accounts for half of the total length of the mixer.

[0005] 3. The multi-segment cover design requires individual cover removal for maintenance of the mixing tank interior, making inspection and maintenance inconvenient. The flushing pipeline is poorly designed, occupying space in the mixer's width and making it highly susceptible to damage during transport; the closed-loop design further complicates cleaning and maintenance; the fixed conical nozzles limit the flushing range and capacity, failing to achieve thorough cleaning. The inlet design is also flawed, causing the incoming material to impact the mixer's drive system, reducing its lifespan; lighter materials (such as cement ash) are easily carried out of the tank by the top flow, resulting in poor mixing performance.

[0006] 4. The unloading mechanism uses a bottom opening in the tank and is controlled by an electric clamp valve. The discharge pipe section is too long, which can easily lead to material accumulation or even blockage of the discharge pipe. The electric clamp valve has a slow response speed, requiring too much time to fully open or close (generally more than 1 minute, and the larger the valve size, the longer the time). Unstable upstream material supply can easily cause material to overflow from the top of the mixer tank. The slow response speed also cannot meet the requirements of electrical automation control.

[0007] 5. The lubrication pipeline is located on the side of the mixer (exposed), which is unsightly and easily damaged by impacts during transportation.

[0008] 6. The shaft end seal and the stirring shaft are connected by a waist-shaped hole. This structure has a friction surface at the mating point, which is easily worn and causes the mating clearance to increase, resulting in abnormal noise at the shaft end.

[0009] 7. Without a material level detection mechanism, the material level height in the tank cannot be detected. Summary of the Invention

[0029] In the continuous mixer without a shared base described in this invention, all components are installed on the mixing tank, resulting in a compact overall structure and significant improvements in equipment performance, safety, maintainability, and transportability.

[0030] Two A-axis end seals and two B-axis end seals are inserted into the mixing tank and secured with bolts. One end of the mixing shaft is connected to the A-axis end seal via a flange, and the other end is connected to the B-axis end seal via a flange. A flat end key is provided in the middle of the flange to assist in transmitting torque.

[0031] The motor and reducer are stacked and connected by a belt, with the belt tensioning mechanism located below the motor support. A synchronous gear is connected to the reducer output end to force the two stirring shafts to rotate synchronously in opposite directions. The reducer output shaft is connected to the shaft end sealing shaft via a perforated flexible coupling.

The cover plate has an observation port and a large maintenance door. Each maintenance door has a limit switch interlocked with the motor; opening the maintenance door automatically shuts off the power.

[0033] In the unloading mechanism, a radar level gauge is installed above the discharge end of the mixing shell via a steel pipe. Water and air pipes are also installed on the steel pipe for periodic flushing of the radar level gauge and the steel pipe. The hydraulic station drives the oil cylinder to extend and retract, which in turn rotates the tilting gate, thus achieving rapid opening and closing of the gate. The hydraulic station, oil cylinder, and tilting gate are all mounted on the unloading gate body, which is bolted to the side of the discharge end of the mixing shell.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0035] The shared base is eliminated, and all components are installed on the mixing tank. The tank has high rigidity, which can avoid deformation during hoisting and transportation.

[0036] The drive system adopts a dual-motor + dual-reducer configuration, with the motors and reducers stacked together, which greatly reduces the length. The two stirring shafts use open gears for synchronization.

[0037] The newly designed cover plate features a 360° rotating nozzle, enabling full-area cleaning of the tank space with high efficiency and water conservation. The cover plate's feed inlet employs a triangular distribution design to prevent the direct flow of lightweight powdery materials, improving mixing performance. The cover plate is equipped with observation and maintenance ports, with the maintenance port featuring a safety switch to enhance equipment maintenance safety.

[0038] The unloading mechanism uses a hydraulic station and cylinders to drive the unloading gate, resulting in a fast response time. An additional radar level gauge component enables precise measurement of the liquid level within the tank. The measurement data can be interlocked with the unloading mechanism to control the material level within the tank, thereby improving the mixing effect.

[0039] All lubrication lines are housed within specially designed concealed steel pipes within the mixing tank, with no exposed pipes on the outside. The overall layout is neat and aesthetically pleasing, eliminating the risk of damage from impacts. All oiling and maintenance points are connected to the side of the tank via oil pipes, enhancing equipment maintainability.

[0040] The connection between the shaft end seal and the stirring shaft has been changed to a flange connection, eliminating mutual friction surfaces, reducing wear, and improving equipment reliability. Attached Figure Description
