[0014] Fig. 1 It is a structure schematic view of the utility model;
[0015] Fig. 2 It is a sectional view of the utility model. DETAILED DESCRIPTION
[0016] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or the prior art, the specific implementation manners of the utility model will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the utility model, and for those skilled in the art, other drawings can be obtained according to these drawings without creative labor, and other implementation manners can be obtained. Embodiment 1
[0017] As Figs. 1-2 shown, a blast furnace tapping hole dust removal cover with a lighting window, comprising a dust removal cover body 1 (specifically referring to one side edge of the dust removal body), a lighting window 2 is arranged on the dust removal cover body, a lighting lamp is fixedly installed outside the lighting window, the irradiation direction of the lighting lamp is towards the lighting window and is obliquely downward for illuminating the inside of the dust removal cover body, frames are arranged around the lighting window, the frames are fixed on the dust removal cover body, a movable door 3 is installed in the frame, and the movable door can close or open the lighting window under the drive of a driving unit.
[0018] The frame comprises a left frame, a right frame, an upper frame and a lower frame, the upper frame and the lower frame are angle steels and are fixed on the dust cover body to form an upper guide groove and a lower guide groove between the dust cover body, and the upper end and the lower end of the movable door are located in the corresponding guide grooves.
[0019] In use, during tapping, the movable door is driven to move by the driving unit, and the illumination window is completely shielded, so that damage of heat radiation to the illumination lamp can be greatly reduced, and the service life of the illumination lamp is improved. Embodiment 2
[0020] The driving unit in embodiment 1 is a cylinder 5, the cylinder body of the cylinder is fixed on the dust cover body or the left frame, and the piston rod 6 of the cylinder is fixedly connected with the movable door.
[0021] Since the movable door is located in the frame, the outer surface of the movable door does not protrude the outer surface of the frame, and the outer surface of the movable door is fixedly installed with a high block 7 for easy installation, and the piston rod is fixedly connected with the high block.
[0022] For the movable door, there are two ways, each having advantages and disadvantages.
[0023] The first way is to cooperate with the fixed door 4, the upper end and the lower end of the fixed door are fixed in the upper guide groove and the lower guide groove, respectively, and the left side of the fixed door shields the left end of the illumination window, the movable door is located outside the fixed door, and when the right end of the movable door abuts against the right frame, the left end of the movable door is located to the left of the right end of the fixed door.
[0024] The second way is that the distance between the left frame and the right frame is not less than 2 times the width of the illumination window, and the width of the movable door is not less than the width of the illumination window.
[0025] Compared with the second way, the stroke of the cylinder in the first way is shorter, and the work required is less, so that the cost can be reduced, but since there are two doors, the fixed door and the movable door, the cooperation requirement is higher. In the second way, the stroke of the cylinder is longer, but there is only one movable door, which is simpler.
[0026] The illumination lamp is fixedly installed on the illumination support, and a camera is also installed on the illumination support. Embodiment 3
[0027] In embodiments 1 and 2, the illumination lamp needs to be controlled manually, and it is easy to forget to turn off the lamp, resulting in a long-lasting lamp, which wastes energy.
[0028] The lighting lamp, the cylinder and the controller are electrically connected, the cylinder transmits the reset (initial position, the lighting window is in the open state) and the extended signal (the lighting window is closed) to the controller, the controller opens the lighting lamp according to the reset signal and closes the lighting lamp according to the extended signal. Or the cylinder is connected with the controller, the controller is connected with the dust removal fan, the dust removal fan is divided into high-frequency operation in the tapping time (the tapping hole is opened, high temperature and high radiation) and low-frequency operation in the non-tapping time (the tapping hole is closed), the controller receives the high-frequency signal and the low-frequency signal transmitted by the dust removal fan, controls the reset action of the cylinder according to the low-frequency signal, opens the lighting window, opens the lighting lamp and closes the lighting lamp after 30 minutes through the time delay switch, controls the piston rod of the cylinder to extend according to the high-frequency signal, and closes the lighting window to avoid the heat radiation of the lighting lamp.
[0029] It should be explained that the above embodiments can be freely combined according to the needs. The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should be considered as the protection scope of the present application.
