Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing equipment, in particular to a simple sealed dust removal and flow-adjustable discharge door. Background Art

[0002] The discharge door of a concrete mixing plant is a crucial component for discharging mixed concrete from the mixing drum. The design and function of the door directly impact the efficiency and quality of concrete discharge. 1. Discharge Door Structure: A discharge door typically consists of the following components: The door body: Typically constructed from high-strength steel plates, providing sufficient strength and durability. The drive mechanism: This mechanism, which may include a hydraulic cylinder, electric actuator, or pneumatic cylinder, controls the opening and closing of the discharge door. The sealing mechanism: This ensures a tight seal when the discharge door is closed, preventing concrete leakage. The guide mechanism: This guides the discharge door for smooth movement during opening and closing, minimizing wear. 2. Discharge Door Types: Discharge doors can be categorized into the following types based on their drive method and structure: Hydraulic drive: This utilizes a hydraulic cylinder, offering powerful driving force and precise control. Electric drive: This utilizes an electric actuator or motor, suitable for smaller mixing plants. Pneumatic drive: This utilizes a pneumatic cylinder, suitable for applications requiring fast response. Manual drive: This mechanism uses a manual handle or lever to control the opening and closing of the discharge door, suitable for smaller mixing plants. 3. Working Principle of the Discharge Door: Opening: When unloading is required, the drive mechanism's telescopic cylinder (such as a hydraulic cylinder) pushes the discharge door open, allowing concrete to flow out of the mixing drum. Closing: After unloading is complete, the drive mechanism pulls the discharge door closed, and a sealing device ensures the mixing drum's tightness. Sealing: When the discharge door is closed, a sealing device (such as a rubber sealing strip) adheres tightly to the door frame, preventing concrete leakage. Proper design and maintenance of the concrete mixing equipment's discharge door ensures efficient, safe, and reliable concrete unloading, improving production efficiency and product quality.

[0003] The discharge door of traditional concrete mixing equipment is controlled by a cylinder. During the discharge process, it can only be fully opened and fully closed. The discharge flow rate cannot be adjusted according to actual production needs. At the same time, the dust generated by the vibrator during discharge cannot be handled and pollutes the environment.
