Description

Technical Field

[0001] The utility model relates to the technical field of graphite heat-insulating cylinders, in particular to a graphite heat-insulating cylinder with a safety protection structure. Background Art

[0002] Single crystal furnace equipment is often used in photovoltaic, microelectronics, non-ferrous metal smelting and other industries. As an important device in single crystal furnace equipment, hot field graphite insulation cylinder has a unique and large demand in the market. Existing hot field graphite insulation cylinders are mostly single-layer insulation cylinders, which can slow down heat loss.

[0003] However, compared with the double-layer insulation tube, its insulation and energy-saving effects are not good. The graphite in the existing insulation tube is inconvenient to install and disassemble, which reduces work efficiency in subsequent maintenance and other work.

[0004] For example, a double-layer hot field graphite insulation cylinder disclosed in Chinese patent CN220867582U is provided, in which a clamping head is provided so that a pressure rod drives a movable block to move downward by pressing a pressure plate, and the clamping head moves downward with the movable block, and the clamping head will pop out when it moves to the bottom of the movable ring, and the movable block is reset by the elastic action of a spring, and the clamping head drives the movable ring to move upward together, and when the top of the movable ring is plugged into the arc block, the clamping head can be smoothly moved to the top of the arc block, and the top cover can be released for quick disassembly during subsequent maintenance, thereby improving work efficiency; by providing a fixed block that is plugged into the base, the fixed block will squeeze the clamping block when it moves downward, and the spring piece will be pressed, and when the fixed block moves to the bottom, the clamping block will clamp and fix the fixed block by the elastic action of the spring piece, so as to fix the bottom of the graphite and avoid graphite damage caused by shaking and collision.

[0005] However, the outer end of the existing graphite insulation tube is not provided with a protective structure, so the graphite insulation tube is easily damaged when it is hit.

[0006] For this reason, we urgently need to provide a graphite insulation cylinder with a safety protection structure. Utility Model Content

[0007] The utility model aims to provide a graphite insulation cylinder with a safety protection structure to solve the problem in the above background technology that the outer end of the graphite insulation cylinder is not provided with a protection structure, so that the graphite insulation cylinder is easily damaged when it is hit.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a graphite insulation cylinder with a safety protection structure, comprising a graphite insulation cylinder, the outer end of which is connected to a protection mechanism, the protection mechanism comprising a protection unit and a connection unit, the protection unit is arranged at the outer end of the graphite insulation cylinder, and the connection unit is arranged at the outer end of the protection unit.

[0009] The protection unit includes a protection ring, a threaded rod, a rotating handle, a bearing, an arc-shaped clamping plate, a rectangular frame, a damping rod, a spring, a circular plate and a buffer rod. The protection ring is arranged at the outer end of the graphite insulation tube, the threaded rod is connected to the inside of the protection ring, the rotating handle is fixedly connected to the end of the threaded rod away from the graphite insulation tube, the bearing is fixedly connected to the outside of the end of the threaded rod away from the rotating handle, the arc-shaped clamping plate is fixedly connected to the outside of the bearing, the rectangular frame is fixedly connected to the outside of the protection ring at an equal distance, the damping rod is fixedly connected to the end of the inner side of the rectangular frame close to the graphite insulation tube at an equal distance, the spring is fixedly connected to the position of the damping rod on the inner side of the rectangular frame, the circular plate is fixedly connected to the other end of the spring, and the buffer rod is fixedly connected to the middle position of the side of the circular plate away from the spring.

[0010] A further improvement is that a first threaded hole is provided in the middle of the protection ring in an equal arc, the outer side of the threaded rod is threadedly connected to the inner side of the first threaded hole, and the side of the arc clamping plate away from the threaded rod abuts against the outer side of the graphite insulation tube. Therefore, after the protection ring is placed on the outer end of the graphite insulation tube, the rotating handle is turned to drive the threaded rod in the first threaded hole to rotate and drive the arc clamping plate to move, until the arc clamping plate moves to contact the outer side of the graphite insulation tube, so that the protection ring can be fixed to the outer end of the graphite insulation tube, and the graphite insulation tube is protected.

[0011] A further improvement is that sliding holes are provided at equal distances in the rectangular frame at one end away from the graphite heat preservation cylinder, and the outer side of the buffer rod is slidably connected to the inner side of the sliding hole. Thus, when the spring drives the circular plate to move, the buffer rod can be driven to slide along the inner side of the sliding hole, thereby limiting the movement of the buffer rod.

[0012] A further improvement is that the end of the damping rod away from the protection ring is fixedly connected to the side of the circular plate close to the spring. Therefore, after the buffer rod at the outer end of the graphite insulation tube is collided and squeezed, under the action of the damping rod in the rectangular frame, the spring will not rebound repeatedly and vibrate repeatedly, causing instability of the graphite insulation tube.

[0013] A further improvement is that the connection unit includes a connection plate and bolts, the connection plate is connected to the upper and lower ends of the protection ring, and the bolts are connected to the upper and lower ends inside the connection plate.

[0014] A further improvement is that a circular hole is provided in the middle of the upper and lower ends of the connecting plate, a second threaded hole is symmetrically provided at the upper and lower ends of the protective ring, a clamping groove is provided at the upper and lower ends of the connecting plate, the outer sides of the upper and lower ends of the protective ring are slidably connected to the inner sides of the clamping groove, the outer sides of the bolts are slidably connected to the inner sides of the circular holes, and the outer sides of the bolts are threadedly connected to the inner sides of the second threaded holes. Thus, after the two protective rings are slid into the clamping grooves at the upper and lower ends of the connecting plate respectively, the bolts are passed through the circular holes and then threadedly connected to the second threaded holes, so that the two protective rings can be fixed to the upper and lower ends of the connecting plate, completing the connection of the protective rings, so that the protective rings fixed at the outer ends of the graphite insulation tube can be fixed to each other, so that the protective unit is more firmly fixed to the outer ends of the graphite insulation tube.

[0015] A further improvement is that a rubber pad is fixedly connected to the side of the arc-shaped clamping plate away from the threaded rod, so that when the arc-shaped clamping plate is moved to contact the outside of the graphite insulation tube, the rubber pad on the outside of the arc-shaped clamping plate contacts the outside of the graphite insulation tube, so that the protective ring can be more firmly fixed to the outer end of the graphite insulation tube.

[0016] In summary, the present application discloses a graphite insulation cylinder with a safety protection structure.

[0017] According to the technical solution, after the protective ring is placed on the outer end of the graphite insulation tube, the rotating handle is turned to drive the threaded rod in the first threaded hole to rotate while driving the arc-shaped clamping plate to move until the arc-shaped clamping plate moves to contact the outer side of the graphite insulation tube. The protective ring can be fixed to the outer end of the graphite insulation tube, so that when the graphite insulation tube is about to be hit, it will first hit the buffer rod, and at the same time the spring is squeezed to play a buffering role, preventing the graphite insulation tube from being directly hit and damaged.

[0018] Furthermore, after sliding the two protective rings into the slots at the upper and lower ends of the connecting plate respectively, the bolts are passed through the round holes and threaded into the second threaded holes, so that the two protective rings can be fixed to the upper and lower ends of the connecting plate, completing the connection of the protective rings. The protective rings fixed to the outer ends of the graphite insulation tube can be fixed to each other, so that the protection unit can be more firmly fixed to the outer end of the graphite insulation tube.

[0029] The protection unit includes a protection ring 201, a threaded rod 202, a rotating handle 203, a bearing 204, an arc-shaped clamping plate 205, a rectangular frame 206, a damping rod 207, a spring 208, a circular plate 209 and a buffer rod 210. The protection ring 201 is arranged at the outer end of the graphite insulation tube 1, the threaded rod 202 is connected to the inside of the protection ring 201, the rotating handle 203 is fixedly connected to the end of the threaded rod 202 away from the graphite insulation tube 1, the bearing 204 is fixedly connected to the outer side of the end of the threaded rod 202 away from the rotating handle 203, the arc-shaped clamping plate 205 is fixedly connected to the outer side of the bearing 204, a first threaded hole of equal arc is opened in the middle position of the protection ring 201, the outer side of the threaded rod 202 is threadedly connected to the inner side of the first threaded hole, and the side of the arc-shaped clamping plate 205 away from the threaded rod 202 abuts against the outer side of the graphite insulation tube 1. Therefore, after the protective ring 201 is placed on the outer end of the graphite insulation tube 1, the rotating handle 203 is rotated to drive the threaded rod 202 in the first threaded hole to rotate while driving the arc clamping plate 205 to move, until the arc clamping plate 205 moves to contact the outside of the graphite insulation tube 1, so that the protective ring 201 can be fixed to the outer end of the graphite insulation tube 1, and the graphite insulation tube 1 is protected.

[0030] The rectangular frame 206 is fixedly connected to the outside of the protection ring 201 at an equal distance, the damping rod 207 is fixedly connected to one end of the inner side of the rectangular frame 206 close to the graphite insulation tube 1 at an equal distance, the spring 208 is fixedly connected to the position of the damping rod 207 on the inner side of the rectangular frame 206, the circular plate 209 is fixedly connected to the other end of the spring 208, and the buffer rod 210 is fixedly connected to the middle position of the side of the circular plate 209 away from the spring 208.

[0034] Embodiment three:

[0035] On the basis of the first embodiment: a rubber pad is fixedly connected to the side of the arc-shaped clamping plate 205 away from the threaded rod 202. Therefore, when the arc-shaped clamping plate 205 is moved to contact the outside of the graphite insulation tube 1, the rubber pad on the outside of the arc-shaped clamping plate 205 contacts the outside of the graphite insulation tube 1, so that the protective ring 201 can be more firmly fixed to the outer end of the graphite insulation tube 1.
