Description

Technical Field

[0001] The utility model relates to the technical field of funnels, and more specifically to a rotary vibrating funnel for detecting the liquid level of molten metal. Background Art

[0002] In the field of metallurgy, metals become molten in a furnace at high temperatures. It is usually necessary to detect the liquid level in the furnace, so a liquid level detection device is needed.

[0003] In the existing liquid level detection device, the probe rod is inserted into the furnace through the lifting mechanism, and then the liquid level is detected by taking pictures with an industrial camera. After the detection is completed, the metal liquid on the probe rod is cooled into slag, and the metal slag on the probe rod needs to be knocked off. The knocked-off metal slag is guided by the sleeve and the funnel and re-enters the furnace. Here, since the copper slag knocked off the probe rod is large and small, the large metal slag will be blocked in the funnel because its width is larger than the passage of the funnel. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] refer to Figure 1-2 A rotary vibrating funnel for detecting the liquid level of molten metal comprises a funnel body 1, wherein the funnel body 1 comprises an outer funnel 12 and an inner funnel 11 rotatably mounted in the outer funnel 12, wherein the inner wall of the outer funnel 12 and the outer wall of the inner funnel 11 are spaced apart to form a cavity 2; a groove 3 communicating with the cavity 2 is formed on the outer wall of the outer funnel 12, and a motor 4 connected to the inner funnel 11 through the groove 3 is mounted on the outer funnel 12; a coil 5 arranged in a surrounding manner from top to bottom is mounted on the inner wall of the inner funnel 11, and a vibrator 6 located in the cavity 2 is mounted on the outer wall of the inner funnel 11. It is understandable that the rotational installation between the inner funnel 11 and the outer funnel 12 can be a contact sliding installation, or other parts can be used for rotational installation, for example: a first annular groove 13 and a second annular groove 14 are formed on the top and bottom of the outer funnel 12, respectively, and a first bearing 131 and a second bearing 132 are installed in the first annular groove 13 and the second annular groove 14, respectively, and the outer ring walls at the top and bottom of the inner funnel 11 are respectively embedded in the first bearing 131 and the second bearing 132. In this way, the two ends of the inner funnel 11 are fixed by the first bearing 131 and the second bearing 132, respectively, and have a rotation function. The function of the slot 3 is to make a channel for the transmission connection between the motor 4 and the inner funnel 11. The vibrator 6 is a prior art, and will not be described in detail here. With such arrangement, when the metal slag enters the inner funnel 11, the motor 4 drives the inner funnel 11 and the roll 5 to rotate, breaking the long or wide metal slag into pieces, and then drives the inner funnel 11 to vibrate through the vibrator 6, so that the metal slag can completely pass through the inner funnel 11 to prevent blockage.

[0023] In some embodiments, reference Figure 2-4 Since the outer wall of the inner funnel 11 is inclined and cannot cooperate with the inner ring of the bearing, a ring seat 111 that is embedded with the inner ring of the first bearing 131 is installed on the outer wall of the top of the inner funnel 11, and the bottom is bent vertically downward to form a ring ring 112 that is embedded with the inner ring of the second bearing 132. Both the ring seat 111 and the ring ring 112 are annular structures, which can be embedded with the inner ring of the bearing more stably.

[0024] In some embodiments, a gear ring 8 is installed at the position of the outer wall of the inner funnel 11 corresponding to the slot 3, and a gear 41 connected to the gear ring 8 is installed at the output end of the motor 4. The motor 4 drives the gear 41, and the gear 41 engages the gear ring 8 to drive the inner funnel 11 to rotate. Of course, it can also be driven by roller contact transmission. Furthermore, a shell 7 that wraps the motor 4 and the slot 3 is installed on the outer wall of the outer funnel 12. The shell 7 can not only fix the motor 4, but also protect the transmission structure.

[0025] In some embodiments, the top of the inner funnel 11 is a feed port 113, the bottom is a discharge port 114, and the inner circle diameter of the coil 5 is larger than the diameter of the discharge port 114. It can be understood that the utility model is used for liquid level detection, and the probe rod needs to pass through the inner funnel 11 for downward detection, so the coil 5 cannot affect the downward movement of the probe rod. Of course, the diameter of the inner circle of the coil 5 is larger than the diameter of the discharge port 114, and the axis of the coil 5 and the axis of the discharge port 114 remain on the same vertical line. Furthermore, a barb 51 is provided on the side of the coil 5 away from the inner wall of the inner funnel 11. Here, the direction of the barb 51 is the same as the rotation direction of the inner funnel 11. When the metal slag is in the inner funnel 11, the barb 51 can hook and cut off the metal slag to prevent the metal slag from sliding in the inner funnel 11.

[0026] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
