The hearth seat 1 has at least two hearth seats, and by installing the hearth in the first installation direction, the trough-shaped heating channel 11 of the hearth can be conveniently passed through or installed by a conveying device for placing products to be heated. The heating element 2 can be heated by the heating rod 21, and the main body of the heating element acts as a mounting seat.
In the embodiment of the present application, two mounting portions 24 may be disposed at two ends of the heating element 2, at least one heating rod 21 is disposed between the two mounting portions 24 along a third mounting direction parallel to the second mounting direction, and an electric heating wire 22 is wound around the heating rod 21 along an axial direction; two sliding fit parts 23 are symmetrically arranged at two ends of the heating element 2, a sliding connection groove 12 is respectively arranged at the lower parts of groove walls at two sides of the groove-shaped heating channel 11, the sliding connection groove 12 penetrates through the heating element 2 along a first installation direction, and the sliding fit parts 23 of each heating element 2 are respectively in sliding fit with the sliding fit grooves at the corresponding sides, so that the heating element 2 can move along the direction of the first installation direction in the groove-shaped heating channel 11.
The heating rod 21 is installed between two installation parts 24, which can be heated by an electric heating wire 22 wound thereon. The sliding connection parts at the two ends of the heating element 2 can be embedded into the sliding connection grooves 12 at the bottom ends of the groove-shaped heating channels 11 and are in sliding fit with each other, so that the heating element 2 provided with the heating rod 21 can slide at the bottom of the groove-shaped heating channels 11, and the sliding connection grooves 12 penetrate through the heating element 2, so that the heating element 2 can slide out of the heating element 2, and the heating element can be detached and is convenient to install. Because the notch of furnace is down in the in-service use, therefore set up the structure of spout through the lateral wall and can avoid heating piece 2 to drop downwards easily and injure the problem of product by a ball, structural design is more reasonable.
Through the technical scheme, one or more heating rods 21 can be arranged on an independent heating piece 2, the heating piece 2 is of a structure which can slide and is convenient to disassemble and assemble and is arranged in the groove-shaped heating channel 11 of the hearth seat 1, so that when one heating rod 21 is damaged or cannot be used, the heating rod 21 can be disassembled together with the heating piece 2 by a sliding disassembly mode from the corresponding hearth seat 1, the disassembly and assembly of the single heating rod 21 are realized, the condition that the whole or most disassembly needs to be replaced is avoided, the maintenance or replacement cost is greatly reduced, and the hearth seat 1 can be replaced by a unit.
In one embodiment, the heating element 2 has a top surface, and the two mounting portions 24 are perpendicular to the top surface of the heating element 2 and are higher than the top surface.
The top surface of the heating element 2 is a transverse surface, parallel to the first mounting direction, on which the heating rod 21 is conveniently mounted between the two mounting portions 24. By means of the two mounting portions 24 above the top, the heating rod 21 is suspended, heated better and prevented from burning out by contact with other components.
