Description

Technical Field

[0001] The present application belongs to the technical field of silicon steel production, and in particular relates to an early warning device installed in an inner cover of an annealing furnace. Background Art

[0002] During the production of oriented silicon steel coils, hydrogen and nitrogen are used as protective gases to ensure that the steel coils can be isolated from the outside world. At the same time, internal methods are used to isolate nitrogen and hydrogen from the furnace. During specific use, workers usually use a crane to lift the inner cover to the steel coil stack and use sealing sand to protect the inner cover's sealing. However, during use, the height of the inner cover needs to meet certain downward pressure requirements. When the height of the inner cover is not pressed down to the appropriate depth of the foundation pit by the hoist or the pressure does not meet the requirements, the inner cover is likely to rub against the bottom of the furnace door or the bottom of the air duct when rotating with the trolley, causing the inner cover to topple or the air duct to break and fall off, causing a major accident, seriously affecting the normal production. Therefore, a device is needed to detect the installation height of the inner cover and issue an early warning to remind the staff to make timely adjustments. Utility Model Content

[0003] The present application aims to at least to some extent solve the technical problems in the prior art such as the inner cover of the annealing furnace being installed too high, resulting in the inner cover tipping over, the air duct breaking, etc. To this end, the present application provides an early warning device for the installation of the inner cover of the annealing furnace.

[0032] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them.

[0033] In the related art, there is a technical problem of inconvenience in the installation process of the inner cover of the annealing furnace. The embodiment of the present application provides an early warning device for the installation of the inner cover of the annealing furnace, which can at least solve the technical problems such as the inner cover tilting and the duct breaking caused by the inner cover of the annealing furnace being installed too high.

[0034] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0035] First, see Figure 1 , Figure 2 , an early warning device for installing an inner cover of an annealing furnace provided in an embodiment of the present application comprises: two columns 1, the two columns 1 are distributed on both sides of the inner cover, the columns 1 are higher than the top of the inner cover, and each of the columns 1 is provided with a detachment detection support frame 4; a lever 2, both ends of which are mounted on the detachment detection support frame 4 located on both sides of the inner cover; a detection device for detecting the distance between the lever 2 and the detachment detection support frame 4; an early warning device for reminding staff, which is electrically connected to the detection device. During use, the inner cover of the annealing furnace moves on the track. When the installation height of the inner cover of the annealing furnace is too high, when the distance between the lever 2 and the detachment detection support frame 4 increases, the detection device converts it into circuit information and triggers the early warning device. The early warning device thereby reminds the staff of the installation height problem of the inner cover of the annealing furnace, thereby facilitating adjustment. When the installation height of the inner cover of the annealing furnace is within the normal range, the distance between the lever 2 and the detachment detection support frame 4 cannot be triggered, and the early warning device will not be triggered.

[0036] In some embodiments, see Figure 1 , Figure 2The detection device is a first proximity switch sensor 3, which is connected to the detachment detection support frame 4, and the detachment detection support frame 4 is electrically connected to the early warning device. Through the above structure, the first proximity switch sensor 3 sets the distance as the distance between the first crystal switch sensor and the surface of the detachment detection support frame 4, and the detected metal is set on the surface of the gear lever 2. When the first proximity switch sensor 3 receives metal information, the early warning device is not triggered. When the first proximity switch sensor 3 does not receive metal information, the early warning device will be triggered.

[0037] In some embodiments, see Figure 2 , Figure 3 The detachment detection support frame 4 includes: a horizontal plate 5, which is vertically connected to the column 1; a baffle 6, the bottom end of which is vertically connected to the free end of the horizontal plate 5, and the baffle 6 is installed on the free end of the horizontal plate 5, and the baffle 6 is arranged parallel to the column 1; a mounting plate 7, which is installed on the upper part of the baffle 6, and the mounting plate 7 is arranged parallel to the horizontal plate 5, and the first proximity switch sensor 3 is installed on the mounting plate 7.

[0038] In some embodiments, see Figure 2 , Figure 3 The detachment detection support frame 4 is provided with a drop signal detection device, and the drop signal detection device can improve the detection accuracy.

[0040] In some embodiments, the drop signal detection device further includes a support plate 10 , and two ends of the support plate 10 are fixedly mounted to the baffle plate 6 and the fixing plate 8 , respectively.

[0041] In some embodiments, see Figure 2The early warning device includes a sound alarm device 11 and an optical signal alarm device 12, the sound alarm device 11 and the optical signal alarm device 12 are connected in parallel, the first proximity switch sensor 3 and the second proximity switch sensor 9 are connected in parallel as a signal detection device, and the early warning device is connected in series with the signal detection device, so that when the first proximity switch sensor 3 or the second proximity switch sensor 9 detects a distance signal, it can be transmitted to the sound and light alarm device to avoid the situation where a single device fails and causes inaccurate detection. When the sound alarm device 11 fails, the staff can still be reminded by an optical signal.

[0042] In some embodiments, the early warning device is installed in the control room, so that the staff can monitor the installation status of the inner cover of the annealing furnace in the control room at any time, so as to deal with it in time.

[0043] In some embodiments, the early warning device is installed on the pillar, so that the staff can monitor the installation status of the inner cover of the annealing furnace on site at any time, so as to handle it in time.

[0044] In some embodiments, see Figure 2 , Figure 3 The fixing plate 8 and the mounting plate 7 are both provided with anti-skid pads 13 to prevent the gear lever 2 from rolling and causing misjudgment.
