  • Publication number: 20210201073
    Abstract: Embodiments of the present disclosure provide an image encoding method and device, and a computer-readable storage medium. The method includes: obtaining a to-be-encoded image set, where the to-be-encoded image set includes at least one to-be-encoded image; extracting feature information of each to-be-encoded image by using a preset feature extraction model, to obtain image feature information; determining an encoding parameter corresponding to the image feature information; and sending the encoding parameter to an image encoder, so that the image encoder performs an encoding operation on the to-be-encoded image based on the encoding parameter. Therefore, the to-be-encoded image can be automatically encoded, image encoding efficiency is effectively improved, and human resources can be saved.

  • Patent number: 9360256
    Abstract: Disclosed in the present invention are a combustion furnace with coaxial staged hearth and heating method thereof, in which the combustion furnace comprises a metal furnace body (40) whose internal part is provided with a furnace chamber. The furnace chamber is divided into two sections at the middle by fire resistant material to form a left and a right independent combustion chambers (18, 19). Two independent combustion chambers (18, 19) are respectively connected with the ends of flue gas chambers (2, 60), while the other ends of the flue gas chambers (2, 60) are respectively connected with a burner (3). The peripherals of two independent combustion chambers (18, 19) are respectively provided with a flue gas heat radiation pipe (14). A middle flue gas chamber (100) is set in the middle position of the furnace chamber. Two ends of the flue gas heat radiation pipe (14) are respectively connected with the flue gas chamber (2, 60) and the middle flue gas chamber (100).

  • Patent number: 9188391
    Abstract: A vertical/horizontal convertible suspending reduction furnace, comprises: a metal furnace body (5) of the reduction furnace, a reduction tank (13), a burner (2) and a suspension device. The metal furnace body (5) of the reduction furnace, which is connected with a sealing head (3) at one end, and connected with a fixed flange (20) of the reduction tank at the other end, is distributed with reduction tanks (13) inside uniformly. Burners (2) are provided symmetrically at the circumference of the metal furnace body (5), and a universal hoisting ring (4) is provided at its central point or off-central point. A steel rope (12), both ends of which are obliquely pulled on the suspension device, is hanged on the universal hoisting ring (4).
