Example Embodiment

[0015] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] Such as figure 1 with figure 2 As shown, this embodiment provides a trolley sealing device, which includes a sealing component and a power component. The sealing component includes a spring steel plate 1, a rotating part-2, a sealing plate 3 and a fiber cotton 4, and the fiber cotton 4 is fixed on On the sealing plate 3, the sealing plate 3 is connected to one end of the rotating part-2, the other end of the rotating part-2 is connected to the spring steel plate 1, and the rotating part-2 is of an'L' shape. The corners of the first rotating part 2 are movably connected to the furnace body, and the power components include an electric push rod 5, two rotating parts 6, a main shaft 7 and a pushing part 8 for moving the sealing part for sealing. The second rotating part 6 It is an'L' shape, one end of the second rotating member 6 is conn...

Abstract

The invention provides a trolley sealing device which comprises sealing components and a power component. Each sealing component comprises a spring steel plate, a first rotating piece, a sealing plate and fiber cotton, the power component comprises an electric push rod, a second rotating piece, a main shaft and push pieces used for moving the sealing components to conduct sealing, the trolley sealing device comprises one or more sealing components and the push pieces, the sealing components and the push pieces are arranged in a paired mode, and the push pieces are all arranged on the main shaft. According to the trolley sealing device, gaps in the combining portions of a furnace body and the two sides of a trolley are sealed, the problem that the sealing performance is damaged due to the fact that the fiber cotton can be ground off through hard sealing after thermal expansion is solved, the main shaft is operated through the electric push rod, unified control over the push pieces and the sealing components is achieved, the push pieces and the sealing components are coincident in operation, and the gaps of the combining portions of the furnace body and the two sides of the trolley are sufficiently sealed.

Description

technical field [0001] The invention relates to a sealing device, in particular to a trolley sealing device. Background technique [0002] During the use of the trolley-type resistance furnace, the sealing condition of the resistance furnace directly affects the uniformity of the temperature in the furnace and power consumption. For the junction between the furnace body and the two sides of the trolley, since the furnace body and the trolley have relative entry and exit, taking into account the expansion after heating, there should be a gap at the joint between the furnace body and the two sides of the trolley. The method of hard sealing is adopted, but the hard sealing will wear off the fiber cotton after the thermal expansion, so the sealing performance is damaged. At the same time, due to the large gap length between the furnace body and the joints on both sides , it should be adequately sealed across the gap and ensure consistent operation to increase productivity. ...
