Technical Field

[0001] The utility model relates to the technical field of silicon rod production, in particular to an anti-deviation device for lifting a furnace barrel. Background Art

[0002] After the silicon rods are produced in the reduction furnace, several vertically placed silicon rods will be produced in the reduction furnace, and all the silicon rods are located on the base. Then the furnace barrel needs to be lifted by a crane to separate the furnace barrel from the base.

[0003] Before lifting the furnace barrel, the base and the furnace barrel need to be disassembled, and then the furnace barrel is lifted up a short distance. The workers observe whether the furnace barrel is offset after it is moved up, so as to judge the verticality of the crane-lifted furnace barrel during movement. In this process, the exhaust gas sucked away by the exhaust gas suction device on the base is prone to reverse flow, causing harm to the workers. In addition, according to the observation of the workers, there is a possibility that the furnace barrel is easily offset, causing the furnace barrel to knock down the vertical silicon rods. Utility Model Content

[0004] In view of the technical problems in the prior art that workers observe the verticality of the rising furnace barrel, which may easily cause exhaust gas backflow and injure workers, and the furnace barrel may easily deviate, causing silicon rods to be knocked down, the utility model provides an anti-deviation device for furnace barrel lifting, which has the advantages of automatically determining whether there is a deviation problem when the furnace barrel is lifted, avoiding exhaust gas backflow and injuring workers, and avoiding silicon rods to be knocked down.

[0033] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model.

[0034] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0035] Example:

[0036] See also Figure 1-Figure 3 , a furnace barrel lifting anti-deviation device, comprising a connector 2, an infrared transmitter 3, an infrared receiver 4 and an alarm. The furnace barrel 1 has a plurality of through holes 5, which can be either light holes or threaded holes. All the through holes 5 are evenly distributed around the furnace barrel 1. The furnace barrel 1 is connected to the base through a plurality of studs, and each stud passes through a through hole 5. When the furnace barrel 1 and the base are separated, all the studs need to be removed.

[0037] Specifically, after all the studs between the base and the furnace barrel 1 are removed, all the through holes 5 on the furnace barrel 1 are exposed. At this time, one end of the connecting piece 2 is inserted into the through hole 5 on the outer wall of the furnace barrel 1, and the other end of the connecting piece 2 extends in a direction away from the outer wall of the furnace barrel 1. At the same time, the infrared emitter 3 is arranged on this end of the connecting piece 2.

[0038] The infrared transmitter 3 transmits infrared rays in a vertical direction, which can be vertically upward or vertically downward. The infrared receiver 4 is arranged in the same vertical direction as the infrared transmitter 3. When the infrared transmitter 3 transmits infrared rays in a vertically upward direction, the infrared receiver 4 is arranged above the infrared transmitter 3. Conversely, when the infrared transmitter 3 transmits infrared rays in a vertically downward direction, the infrared receiver 4 is arranged below the infrared transmitter 3. This allows the infrared receiver 4 to receive the infrared signal emitted by the infrared transmitter 3. A certain distance is always maintained between the infrared transmitter 3 and the infrared receiver 4.

[0039] In addition, the infrared receiver 4 is electrically connected to the alarm and is set so that when the entire system is powered on and installed, the system is turned on and the infrared receiver 4 receives an infrared signal, the alarm will not sound an alarm. When the infrared receiver 4 does not receive an infrared signal, the alarm will sound an alarm.

[0040] The working principle of this embodiment is that the connecting piece 2 is first inserted into the through hole 5 of the side wall of the furnace barrel 1, and an infrared transmitter 3 is arranged at the other end of the connecting piece 2. The infrared ray emitted by the infrared transmitter 3 is directly facing the infrared receiver 4. If the infrared ray emitted by the infrared transmitter 3 deviates from the infrared receiver 4 (that is, the infrared receiver 4 cannot receive the infrared signal) during the process of lifting the furnace barrel 1 by the crane, the alarm will sound an alarm to remind the operator that the furnace barrel 1 has deviated.

[0041] Through this technical solution, the verticality of the movement of the furnace barrel 1 can be automatically determined when the furnace barrel 1 is lifted by a crane, thereby eliminating the need for workers to observe and avoiding injuries to workers caused by exhaust gas backflow. When the furnace barrel 1 is offset, the operating worker can be reminded in time to avoid the problem of silicon rods being knocked over.

[0042] Generally speaking, in order to facilitate the installation of the infrared receiver 4, the light emitted by the infrared transmitter 3 is set in a vertical downward direction, and the infrared receiver 4 is installed on the ground, that is, below the infrared transmitter 3, and the receiving end of the infrared receiver 4 is on a horizontal plane.

[0043] In one specific embodiment:

[0044] The anti-deviation device further comprises a support plate 6 and a bolt 7, wherein the support plate 6 is arranged at the middle of one end of the connecting member 2 away from the side wall of the furnace barrel 1, and has a threaded hole in the middle of the support plate 6. The threaded hole on the support plate 6 is matched with the bolt 7, and one end of the bolt 7 can abut against the outer wall of the furnace barrel 1.

[0045] In this embodiment, when the connecting member 2 is installed on the furnace barrel 1, the connecting member 2 can be fixed on the furnace barrel 1 by rotating the bolt 7 so that one end of the bolt 7 abuts against the outer wall of the furnace barrel 1 and the bolt 7 is tightened, thereby preventing the connecting member 2 from shaking during the process of lifting the furnace barrel 1 by a crane.

[0046] In another specific embodiment:

[0047] The anti-deviation device also includes a movable plate 8, wherein the middle part of one side surface of the movable plate 8 and the bolt 7 can be rotatably connected to one end of the side surface of the furnace barrel 1, so that when the connecting piece 2 is installed, the movable plate 8 can be in contact with the side wall of the furnace barrel 1 during the process of rotating the bolt 7, thereby avoiding the wear of the rotating guide column of the bolt 7 on the outer wall of the furnace barrel 1.

[0048] In another specific embodiment:

[0049] A slide groove is provided on the connecting member 2, the length direction of the slide groove is consistent with the length direction of the bolt 7, and one end of the movable plate 8 is also slidably arranged in the slide groove. By sliding the movable plate 8 on the slide groove, when the bolt 7 is rotated, the movable plate 8 can be prevented from rotating together.

[0050] Preferably, the side of the movable plate 8 that can contact the side wall of the furnace barrel 1 is set to an arc-shaped surface structure, and the entire side surface of the movable plate 8 can contact the outer wall surface of the furnace barrel 1. By increasing the contact area between the movable plate 8 and the outer wall of the furnace barrel 1, the friction between the movable plate 8 and the side wall of the furnace barrel 1 is increased, thereby improving the fixing effect of the movable plate 8 on the connecting piece 2.

[0051] In another specific embodiment:

[0052] The section of the connecting member 2 inserted into the through hole 5 is cylindrical, and the cylindrical structure can be completely inserted into the through hole 5 .

[0053] One end of the connecting member 2 away from the furnace barrel 1 extends in the horizontal direction, so that the bolt 7 extends and moves in the horizontal direction.

[0054] In another specific embodiment:

[0055] The bottom of the side wall of the furnace barrel 1 has an annular connecting groove structure, and the connecting piece 2 is L-shaped, and the length of one end of the connecting piece 2 that can be inserted into the through hole 5 is less than the width of the connecting groove. Through this structure, the problem of difficult installation is avoided.

[0056] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
