A self-cleaning horizontal conveying device for filling micro powder in gaps of a cement particle structure comprises a plurality of conveying pipes which can be butted and combined, an air pressure pipeline, a one-way valve matched with the air pressure pipeline, a gear ring, a bearing matched with the gear ring, a stirring shaft used for installing and fixing a cleaning steel brush or a cleaning blade, and a driving gear meshed with the gear ring; a motor is used as a power source to drive a driving gear to rotate, the driving gear is meshed with a gear ring, and the gear ring drives a stirring shaft to rotate along the inner wall of a conveying pipe; a cleaning steel brush or a cleaning blade which is fixedly arranged on the stirring shaft is contacted with the inner wall of the conveying pipe to forcibly remove the micro powder attached or bonded on the inner wall of the conveying pipe; meanwhile, the air pressure pipeline is opened to supplement airflow in the conveying pipe, and the falling micro powder generated during forced removal is taken away by the airflow. According to the running condition of the equipment, the motor is started to work at regular time, and micro powder adhered to the inner wall of the conveying pipe is removed in time, so that the safe running of the horizontal conveying pipeline is realized. Through practical application, unexpected satisfactory effect is obtained.
Description
Technical Field
The utility model relates to a miropowder production line field, concretely relates to self-cleaning formula horizontal transport device of miropowder is filled in cement particle structure space for the safety of miropowder is filled in cement particle structure space is carried.
Background
At present, the performance of concrete is improved by adding fly ash and slag micropowder into wall materials, cement and concrete used in the construction industry at home and abroad. The defects are overcome, and the performance of the concrete is influenced by the fineness of the fly ash and the hydration heat generated when the slag micro powder is hydrated. In the field of high performance concrete, ultrafine materials are required to supplement these defects, and silica fume is commonly used because of its properties, which leads to an increase in the water demand of the concrete. Among these, typical technologies are silicon carbide micropowder production lines, such as: a silicon carbide micro powder production line disclosed in Chinese patent CN 201420121208. In the production practice, the low-angle or zero-angle horizontal conveying of the micropowder generally adopts an air pipe conveying technology. The micro powder filled in the gaps of the cement particle structure has the characteristics of easy adhesion to the inner wall of the conveying pipeline and difficult cleaning. Therefore, the design of a self-cleaning horizontal conveying device for the micro powder filled in the gaps of the cement particle structures is urgently needed, and the self-cleaning horizontal conveying device is used for safely conveying the micro powder filled in the gaps of the cement particle structures.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a self-cleaning formula horizontal conveyor of miropowder is filled in cement particle structure space for the safe transport of miropowder is filled in cement particle structure space can effectively prevent or clear away the bonding of miropowder in pipeline.
The technical scheme of the utility model: the self-cleaning horizontal conveying device for filling the gaps of the cement particle structure with the micro powder comprises a plurality of conveying pipes which can be butted and combined, an air pressure pipeline, a one-way valve matched with the air pressure pipeline, a gear ring, a bearing matched with the gear ring, a stirring shaft for mounting and fixing a cleaning steel brush or a cleaning blade, and a driving gear meshed with the gear ring; one end of the conveying pipe is provided with a flange, and the other end of the conveying pipe is provided with an undercut flange which is connected with the flange in a matching way; a bearing is arranged in the undercut flange and is fixedly mounted with the gear ring in a matching way; one side of the side concave flange is provided with a power input port, and the driving gear is meshed with the gear ring through the power input port; the diameter of the inner ring of the gear ring is equal to the diameter of the inner wall of the conveying pipe; at least one stirring shaft fixing seat is arranged on the inner side of the inner ring; a stirring shaft parallel to the axis of the conveying pipe is fixed on the stirring shaft fixing seat; the pipe wall is provided with air pressure pipelines which are arranged at equal intervals.
After the structure is adopted, the motor is used as a power source to drive the driving gear to rotate, the driving gear is meshed with the gear ring, and the gear ring drives the stirring shaft to rotate along the inner wall of the conveying pipe; a cleaning steel brush or a cleaning blade which is fixedly arranged on the stirring shaft is contacted with the inner wall of the conveying pipe to forcibly remove the micro powder attached or bonded on the inner wall of the conveying pipe; meanwhile, the air pressure pipeline is opened to supplement airflow in the conveying pipe, and the falling micro powder generated during forced removal is taken away by the airflow. According to the running condition of the equipment, the motor is started to work at regular time, and micro powder adhered to the inner wall of the conveying pipe is removed in time, so that the safe running of the horizontal conveying pipeline is realized.
The utility model has the positive effects that; can forcibly remove the micro powder adhered on the inner wall of the conveying pipe, overcomes the defect of difficult removal in the prior art, and realizes the purpose of safe operation of the horizontal conveying pipe. Through practical application, unexpected satisfactory effect is obtained.
