Embodiment 1

[0024] Such as Figure 1-2 As shown, a high-efficiency and energy-saving aluminum rod hybrid heating furnace includes a single-rod furnace 01 and a multi-rod furnace 02 integrated with the single-rod furnace 01. The single-rod furnace 01 includes a first furnace body 11 and a heating zone 12 provided in the first furnace body 11 , and spray guns 13 for heating a single aluminum rod 06 are arranged above and below the first furnace body 11 . The above-mentioned heating zone 12 is a chamber dedicated to adding the single rod furnace 01 . The multi-rod furnace 02 includes a second furnace body 21 integrated with the first furnace body 11 on one side of the first furnace body 11 , and a preheating zone 22 communicated with the heating zone 12 in the second furnace body 21 . The above-mentioned preheating zone 22 is a chamber dedicated to preheating a plurality of aluminum rods 06 arranged side by side. The main function of the preheating zone 22 is to use the residual heat of th...

Embodiment 2

[0027] Such as Figure 3-4 Shown, under the condition that does not change embodiment 1 structure. A heat exchanger 05 is provided between the exhaust pipe 17 and the spray gun 13 . The heat exchanger 05 includes an outer pipe body 52 communicating with the exhaust pipe 17 and an inner pipe body 51 communicating with the pipe body of the spray gun 13 to supply combustion-supporting air, and a device for controlling discharge is also arranged between the outer pipe body 52 and the exhaust gas. Valve 53. The function of the heat exchanger 05 is to use the waste heat discharged from the preheating zone 22 into the outer tube body 52 to preheat the combustion-supporting air supplied to the spray gun 13, so as to further realize the purpose of saving energy.

Embodiment 3

[0029] Such as Figure 5 Shown, under the condition that does not change embodiment 1 and embodiment 2 structure. Remove the baffle plate 03 and replace it with the structure of the notch 30 . Between the preheating zone 22 and the heating zone 12, there is a gap 30 corresponding to the diameter and width of the aluminum rod. When in use, the aluminum rod 06 can just pass through the width of the gap 30, and the diameter and width of the aluminum rod 06 is smaller than the width of the gap 30, which can effectively control the aluminum rod 06 to block the hot gas in the single rod furnace 01 and discharge it into the multi-rod furnace Timing within 02.

Abstract

The invention discloses a high-efficient and energy-saving aluminum rod mixing heating furnace applied to the aluminum extrusion process. The heating furnace comprises a single-rod furnace and a multi-rod furnace which is integrated with the single-rod furnace. The single-rod furnace comprises a first furnace body, a heating zone arranged in the first furnace body, and spray guns which are used for heating the single-rod furnace and are respectively arranged on the upper part and lower part of the first furnace body. The multi-rod furnace comprises a second furnace body which is arranged on one side of the first furnace body and integrated with the first furnace body, and a preheating zone which is in communication with the heating zone and is arranged in the second furnace body. The first furnace body and the second furnace body are provided with a pipe body which is used for communicating the heating zone with the preheating zone, and the pipe body is provided with a pressure sensor. The high-efficient and energy-saving aluminum rod mixing heating furnace has the advantages that the energy is saved, the heat loss is small, the preheating time is short, the heating efficiency of aluminum rods is high, the daily maintenance and repairing are applicable, and the effect that the aluminum rods are in gradient heating is realized.

Description

technical field [0001] The invention relates to a heating furnace, in particular to a high-efficiency and energy-saving aluminum rod mixing heating furnace used in the aluminum material extrusion process. Background technique [0002] At present, the multi-rod furnaces appearing on the market mainly heat the air in the furnace through the burner, and use the hot gas to heat multiple aluminum rods arranged side by side. The multi-rod furnace has the disadvantages of long preheating time and inability to realize gradient heating. The single-rod furnace adopts a structure in which a single aluminum rod is heated directly by flame through the spray guns on both sides of the furnace body. Although the single-rod furnace can shorten the preheating time, the high-temperature flue gas generated during the heating process will be directly discharged to the furnace body, resulting in waste of heat energy. Contents of the invention [0003] In view of the above problems, the object...
