Embodiment Construction

[0015] The present invention will be further described below according to accompanying drawing.

[0016] figure 1 The bell-type solid melting furnace shown includes a gantry 1, a furnace body 2, a trolley 3 and a track 4. The gantry 1 is a rectangular frame, and the gantry 1 straddling two mutually parallel tracks is fixedly connected to the ground, and a hoist 1.1 is provided in the center of the top beam for hoisting the furnace body 2 below. When the gantry 1 lifts the body of furnace 2 to the highest position, the bottom surface of the furnace bottom 2 is higher than the highest position where the workpiece 5 is loaded on the trolley 3 . The trolley 3 is a flatbed structure, the top surface is placed with a furnace bottom 2.1 made of refractory material, the bottom is provided with a roller 3.2, and the trolley 3 is driven by an external reducer 3.1 to move the roller 3.2 reciprocatingly along the track 4. Body of heater 2 is the main component among the present inventio...

Abstract

The invention discloses a bell-type solid melting furnace which comprises a portal frame, a furnace body, a trolley and a rail. The portal frame is arranged across the rail, and a winch is arranged in the middle of a top beam. The trolley is of a platform lorry structure, the top face of the trolley is provided with a furnace bottom made of fire-resistant materials, the bottom of the trolley is provided with idler wheels, and the trolley moves in a reciprocating mode along the rail due to the fact that a matched speed reducer drives the idler wheels. The furnace body is made of fire-resistant materials in a coated mode and is of a bell type, a hook on the top of the outer wall forms a lifting mechanism due to the fact that the winch matched with the portal frame drags through a steel wire rope, the furnace body is a container with a downward opening, the opening is matched with the furnace bottom, and the inner wall of a hearth is provided with a necessary heating device. The furnace body is of a bell type, the opening of the furnace body is matched with the furnace bottom after the hung furnace body is descended, the combination portion is tightly sealed due to the fact that self weight of the furnace body is large, heat loss does not occur during heating, and meanwhile no air enters the hearth. Accordingly, heating efficiency is high, heating quality is good, and oxidation layers on the surfaces of workpieces are few after heating.

Description

technical field [0001] The invention relates to an industrial furnace structure, in particular, the invention relates to a bell type solid melting furnace. Background technique [0002] The trolley-type solid melting furnace for industrial application is relatively large in volume, and the furnace body is fixed, and the configured trolley carries the workpiece into and out of the furnace through the reserved furnace door. The furnace doors of the trolley-type solid melting furnaces in the prior art mainly include side-by-side doors, single-leaf doors or lifting doors. These furnace doors are very simple in structure and easy to open and close. The matching trolley is accessible. However, the trolley-type solid melting furnaces used in industrial applications generally have the problem that the furnace doors are not closed tightly. The reason is that these furnace doors are heavy, and the hinges supporting the furnace doors are worn and deformed severely, resulting in a gap ...
