Description

Technical Field

[0001] The utility model relates to the technical field of refining furnaces, and particularly relates to a moving elbow for switching stations of a double-station refining furnace. Background Technique

[0002] A double-station vacuum refining system consists of a vacuum pump system, an air cooler, a vacuum pipeline, a vacuum pipeline for switching between two stations, a sealing elbow, etc.; it is used to connect two sets of gas coolers to a vacuum main valve to a vacuum pumping system respectively, and has the function of converting the same vacuum system between two treatment stations. The commonly used moving elbow is usually assisted by a hoist trolley to move and switch stations. It is controlled by two lifting cylinders respectively to lift and lower the moving elbow, resulting in asynchronous lifting of the two cylinders and operation errors.

[0003] In the related art, currently, a synchronous motor is added between the two lifting cylinders, and the asynchronous situation is alleviated, but it does not achieve complete synchronization, still resulting in poor sealing of the moving elbow and poor vacuum pumping; moreover, the hoist trolley is lifted and lowered by a flexible cable suspension, resulting in shaking or swinging during the lifting and horizontal movement; at the same time, when the vacuum pipeline of one station is in production treatment, smoke and dust will be generated at the other station, causing environmental pollution. Content of the Utility Model

[0004] The purpose of the utility model is to provide a moving elbow for switching stations of a double-station refining furnace to solve at least one of the problems and defects mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A moving elbow for switching stations of a double-station refining furnace, comprising:

[0007] A first-station vacuum pipe, a vacuum pump pipe, a second-station vacuum pipe, and a moving elbow. A moving lifting mechanism is arranged at the top of the moving elbow;

[0008] The pipe holes at both ends of the moving elbow are movably connected to the first-station vacuum pipe and the vacuum pump pipe, and the second-station vacuum pipe and the vacuum pump pipe respectively through the moving lifting mechanism;

[0009] Connecting plates are respectively arranged on both sides of the moving elbow, and covers are respectively arranged at the bottoms of the two ends of the connecting plates.

[0010] According to the moving elbow for switching stations of the double-station refining furnace in this solution, it has at least the following technical effects:

[0011] The movable elbow for the station switching of the double-station refining furnace enables the tube holes at both ends of the movable elbow to be movably connected to the first-station vacuum tube and the vacuum pump tube, as well as the second-station vacuum tube and the vacuum pump tube respectively by arranging a movable lifting mechanism at the top of the movable elbow, so as to freely switch between the first-station vacuum tube and the second-station vacuum tube. Compared with the traditional use of two lifting cylinders, it effectively ensures the synchronous lifting of the movable elbow, guarantees the precise docking of the tube holes at both ends of the movable elbow with the vacuum tube, reduces the operation error, and thus improves the sealing effect between the movable elbow and the vacuum tube;

[0012] Meanwhile, connecting plates are arranged on both sides of the movable elbow, and covers are respectively arranged at the bottoms of the connecting plates. When the movable elbow switches to the first-station vacuum tube, one of the covers covers the second-station vacuum tube; when the movable elbow switches to the second-station vacuum tube, the other cover covers the first-station vacuum tube, which can effectively seal the vacuum tube of the other unproductive station and prevent the occurrence of dust emission accidents, avoiding environmental pollution caused by smoke and dust.

[0013] As a further solution of the present utility model: The moving mechanism includes a track and a moving trolley arranged on the track.

[0014] As a further solution of the present utility model: The moving trolley is provided with a plurality of guide rods, and the plurality of guide rods are respectively connected to the top of the movable elbow.

[0015] As a further solution of the present utility model: A lifting device is arranged between the plurality of guide rods, a connecting rod is arranged at the bottom of the lifting device, and the connecting rod is connected to the top of the movable elbow.

[0016] Since the moving mechanism includes a track and a moving trolley arranged on the track, the moving trolley is provided with a plurality of guide rods, the plurality of guide rods are respectively connected to the top of the movable elbow, a lifting device is arranged between the plurality of guide rods, a connecting rod is arranged at the bottom of the lifting device, and the connecting rod is connected to the top of the movable elbow, the guide rods play a guiding role in the lifting of the movable elbow, and can prevent the movable elbow from shaking or swinging during the moving process, improving the stability of the movable elbow when switching stations. And compared with the traditional lifting device being located below the movable elbow, the present lifting device is arranged at the top of the movable elbow, which is convenient for the maintenance or replacement of the lifting device.

[0017] As a further solution of the present utility model: Car stop limit blocks are respectively arranged at both ends of the track.

[0018] By respectively arranging car stop limit blocks at both ends of the track, it can effectively prevent the moving trolley from accidentally derailing during operation, ensuring the safe operation of the equipment. At the same time, by adding corresponding time control and in-place limit alarm functions to the control program, when the normal station switching time of the moving elbow is exceeded, the motor will cut off the power, preventing the motor from continuously being powered on in the case of limit failure and damaging the motor and the reducer.

[0019] As a further solution of the present utility model: derailment baffles are respectively arranged on the outer sides of the two sides of the track.

[0020] By respectively arranging derailment baffles on the outer sides of the two sides of the track, it can timely stop the continuous movement of the moving trolley, avoid accidental derailment of the moving trolley during operation, and further ensure the safe operation of the equipment.

[0021] As a further solution of the present utility model: sealing strips are respectively arranged on the first-station vacuum tube hole, the vacuum pump tube hole, and the second-station vacuum tube hole.

[0022] Since sealing strips are respectively arranged on the first-station vacuum tube hole, the vacuum pump tube hole, and the second-station vacuum tube hole, it can prevent dust from leaking out from the gap between the moving elbow tube hole and the vacuum tube hole during the refining process, effectively ensuring the sealing performance after the moving elbow is docked with the vacuum tube. At the same time, the tight connection between the vacuum pump tube and the moving elbow ensures the vacuum pumping environment and meets the extraction of vacuum. Description of the Drawings
