Description

Technical Field

[0001] The utility model relates to the technical field of resistance furnaces, in particular to a furnace top structure of a high-temperature resistance furnace. Background Art

[0002] A resistance furnace is an industrial furnace that uses electric current to generate heat from the electric heating elements or heating medium inside the furnace, thereby heating the workpiece or material. It is a heating furnace that uses electric current to pass through the resistance material to generate heat energy. Resistance furnaces are used in the machinery industry for heating metals before forging, heating metal heat treatment, brazing, powder metallurgy sintering, glass and ceramic roasting and annealing, melting low-melting-point metals, drying sand molds and paint films, etc.

[0003] There are many types of resistance furnaces, including box-type and cylindrical types, and their opening and closing methods are also diverse, including front-side door opening and top-opening methods. Resistance furnaces with top opening and closing are generally used for processing large materials, and the furnace top can be directly raised to facilitate material removal. However, in the prior art, the traditional resistance furnace top is mostly directly fixed on the inner wall of the upper cover. After processing is completed, the furnace top temperature is relatively high. After opening, when removing materials, the furnace top is located between the furnace body and the upper cover, which is very likely to cause burns. Therefore, the utility model proposes a high-temperature resistance furnace top structure to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high-temperature resistance furnace top structure. By setting a lifting mechanism and a rotating mechanism, when taking materials, the rotating plate drives the furnace top to rotate and flips the furnace top into the upper cover to shield the furnace top and avoid burns when taking materials.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-temperature resistance furnace roof structure includes a furnace body and an upper cover, wherein a rotating rod is connected to the side walls at both ends of the upper cover for rotation, a rotating plate is fixedly sleeved on the rotating rod, and the lower end of the rotating plate is fixedly connected to the furnace top, and second fixed blocks are fixedly connected to the side walls at both ends of the furnace body, and the upper ends of the two second fixed blocks are fixedly connected to vertical rods, and racks are provided on the two vertical rods, and gears matching the racks are fixedly sleeved on both ends of the two rotating rods, and first fixed blocks are fixedly connected to the rear wall of the furnace body and the rear wall of the upper cover, and a lifting mechanism for lifting the upper cover is provided between the two first fixed blocks, and a purification mechanism for purifying exhaust gas generated during the heating process is provided at the upper end of the upper cover.

[0007] Preferably, the lifting mechanism includes two symmetrically arranged electric push rods fixedly connected to the upper end of the first fixed block located below, and the telescopic ends of the two electric push rods are fixedly connected to the lower end of the first fixed block above.

[0008] Preferably, the purification mechanism includes a purifier installed on the upper cover, and an exhaust pipe is provided on the side wall of the purifier.

[0009] Preferably, an air intake fan is provided at the upper end of the upper cover, and the air intake fan is connected to the purifier through an air intake pipe.

[0010] Preferably, a furnace bin is provided inside the furnace body, and the furnace top cooperates with the furnace bin.

[0011] Preferably, a plurality of through holes are provided on the rotating plates located on both sides of the furnace top, and the plurality of through holes are arranged at equal intervals.

[0012] Preferably, torsion springs are provided at the rotational connections between the two ends of the rotating rod and the two sides of the upper cover.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting up a lifting mechanism and a rotating mechanism, when the processing is completed and the material needs to be taken, the telescopic end of the electric push rod is driven to extend, driving the upper cover to move up and complete the opening of the cover. During the opening process, when the upper cover reaches the appropriate height, under the action of the rack, the gear rotates, driving the rotating rod and the rotating plate to rotate, thereby driving the furnace top to rotate and flip the furnace top into the upper cover to cover the furnace top, avoiding burns when taking materials, and greatly improving the safety performance of the device.

[0015] 2. By setting up a purification mechanism, a lot of waste gas will be generated in the furnace during the material processing. At this time, the suction fan is driven, and the suction fan can extract the waste gas generated in the furnace and transport it to the purifier through the air inlet pipe to purify the waste gas. It can effectively prevent the waste gas from being directly discharged and posing a threat to the health of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Reference Figure 1-6 The two ends of the upper cover 2 are connected to the upper cover 2, and the two ends of the upper cover 2 are connected to the upper cover 2. The upper cover 2 has a rotating rod 14 at its two ends, and a rotating plate 13 is fixedly sleeved on the rotating rod 14. The lower end of the rotating plate 13 is fixedly connected to the furnace top 12. The two end walls of the furnace body 1 are fixedly connected to the second fixed block 7. The upper ends of the two second fixed blocks 7 are fixedly connected to the vertical rod 9. The two vertical rods 9 are provided with racks, and the racks are arranged at a position near the upper end of the vertical rod 9. The two ends of the two rotating rods 14 are fixedly sleeved with gears 16 that match the racks. Torsion springs 15 are provided at the rotating connections between the two ends of the rotating rod 14 and the two sides of the upper cover 2. The torsion springs 15 can limit the rotating rod 14. In the initial state, the rotating plate 13 is in a horizontal state. When the rotating rod 14 rotates, the torsion spring 15 accumulates force. When the gear 16 is not engaged with the rack, the rotating plate 13 can be quickly reset under the action of the torsion spring 15.

[0025] A first fixed block 5 is fixedly connected to the rear wall of the furnace body 1 and the rear wall of the upper cover 2. A lifting mechanism for lifting the upper cover 2 is provided between the two first fixed blocks 5. The lifting mechanism includes two symmetrically arranged electric push rods 6 fixedly connected to the upper end of the first fixed block 5 located below. The telescopic ends of the two electric push rods 6 are fixedly connected to the lower end of the first fixed block 5 above.

[0026] The upper end of the upper cover 2 is provided with a purification mechanism for purifying the exhaust gas generated during the heating process. The purification mechanism includes a purifier 3 installed on the upper cover 2, an exhaust pipe 10 is provided on the side wall of the purifier 3, and an intake fan 4 is provided at the upper end of the upper cover 2.

A plurality of through holes 11 are opened on the rotating plates 13 on both sides of the furnace top 12. The plurality of through holes 11 are arranged at equal intervals. The furnace bin 8 and the furnace top 12 are both made of refractory materials.

[0028] When the present invention is used, first, the material to be processed is placed in the furnace bin 8, and then the telescopic end of the electric push rod 6 is driven to retract, driving the upper cover 2 to move down and merge with the furnace body 1. In the process of processing the materials, a lot of exhaust gas will be generated in the furnace body 1. At this time, the suction fan 4 is driven, and the suction fan 4 can extract the exhaust gas generated in the furnace body 1 and transport it to the purifier 3 through the air inlet pipe to purify the exhaust gas, which can effectively avoid the exhaust gas being directly discharged and posing a threat to the health of the staff. When the processing is completed and the material needs to be taken, the telescopic end of the electric push rod 6 is driven to extend, driving the upper cover 2 to move up, and completing the cover opening. During the cover opening process, when the upper cover 2 reaches the appropriate height, under the action of the rack, the gear 16 rotates, driving the rotating rod 14 and the rotating plate 13 to rotate, thereby driving the furnace top 12 to rotate, and flipping the furnace top 12 into the upper cover 2, so as to shield the furnace top 12 and avoid burns when taking materials.
