The invention discloses a cladding-type petroleum drill pipe surface rust removing device. The cladding-type petroleum drill pipe surface rust removing device comprises an annular rotary plate arranged on the outer diameter of a petroleum drill pipe in a sleeved mode, a plurality of sleeves are arranged on the outer surface of the annular rotary plate, and the two ends of each sleeve are opened. The cladding-type petroleum drill pipe surface rust removing device further comprises a sliding column penetrating through the annular rotary plate, one end of the sliding column extends into the inner cavity in each sleeve, the sleeves and the sliding column are connected in a sleeved through threads, the end, extending into the sleeves, of the sliding column is a rotary knob end, and a strip-shaped groove is formed in the end face of the rotary knob end; a universal ball is connected to the other end of the sliding column and connected to the outer diameter face of the petroleum drill pipe in a pressed mode; three vertexes of a triangular plate are connected with the annular rotary plate through three connecting columns, the triangular plate is connected with a hydraulic cylinder, an output shaft of the hydraulic cylinder penetrates through the triangular plate and points to the petroleum drill pipe, an arc-shaped embracing plate is connected to the outer diameter face of the petroleum drill pipe in a pressed mode, and abrasive paper is arranged on the side, facing towards the petroleum drill pipe, of the arc-shaped embracing plate. The cladding-type petroleum drill pipe surface rust removing device can be used for fast removing substances on the surface of the petroleum drill pipe and reduce manual labor intensity.

The invention discloses a discharge structure of a glass kiln. The glass kiln comprises a material channel shell of which the bottom is provided with a discharge hole and a material channel arranged inside the material channel shell as well as a material channel discharge bottom brick, a discharge brick and a heat resistant hole plate which are sequentially arranged below the material channel from top to bottom, wherein the material channel discharge bottom brick, the discharge brick and the heat resistance hole plate are respectively provided with a first discharging part, a second discharging part and a third discharging part, and two sides of each second discharging part are provided with a molybdenum electrode; and the heat resistant hole plate is arranged below the discharge hole, and the side of the heat resistant hole plate in contact with glass liquid is provided with more than one heating rod. The invention has the advantages that degenerative glass liquid on the bottom layerof the material channel can be completely and thoroughly discharged; the main glass liquid temperature of the material channel cannot be influenced by discharging; the discharging quantity can be freely regulated and controlled as required; the structure is simple to operate and only needs remote current regulation without site operations; and the cost of the discharge structure is low, which is beneficial to the popularizing.

The invention discloses an intelligent control banana seedling raising device. The seedling raising box is provided with a seedling raising room and a flip cover, and a tray for cultivating banana seedlings is placed in the seedling raising room. system, an illumination control system and a control device, the control device is respectively connected with the spray system, the nutrient solution spray system, the ventilation system, the air purification system, the heating system, and the illumination control system; the control device includes a circuit control module and a wireless receiving and transmitting The module and the circuit control module are electrically connected to the wireless receiving and transmitting module, and the wireless receiving and transmitting module is matched and connected with a mobile terminal. By setting up a wireless receiving and transmitting module and adopting a wireless networking method to carry out remote intelligent adjustment and control of the growth elements required for banana seedling cultivation, the operation is convenient, no on-site operation is required, and time and effort are saved.

The invention relates to a concrete crack repair material and method, in particular to a concrete crack repair material and method based on the mineralization deposition of facultative aerobic mixed bacteria. The method solves the problems that the repair efficiency of the existing concrete crack repair method based on pure bacteria mineralization deposition is significantly reduced in an anoxic environment, and the preparation process of pure bacteria is relatively expensive. The invention provides a concrete crack repair material and method based on the mineralization deposition of facultative aerobic mixed bacteria. The facultative aerobic mixed bacteria can grow in an aerobic or anaerobic environment, and generally aerobic growth is the main method. , aerobic respiration under aerobic conditions, and anaerobic respiration or fermentation under hypoxic or anaerobic conditions. Therefore, facultative aerobic mixed bacteria are more suitable for actual concrete structures, and are beneficial to crack repair in the direction of crack depth.
