Embodiment 2
[0046] The other parts are the same as in Example 1, except that the heat storage block 5 is selected as a single-use honeycomb. The service life of the heat storage block 5 in this way is 1 year, and the service life in a large heating furnace is half a year.
Embodiment 3
[0048] The other parts are the same as in Example 2, except that the heat storage block 5 is selected as a mixture of small balls and honeycombs, and the ratio of small balls to honeycombs is 9:1, which is an optimal implementation mode. 5 has a service life of 8 years and needs to be replaced 10% every year.

The present invention relates to the technical field of heating furnaces, in particular to an environmentally friendly heat storage trolley heat treatment furnace, which includes a heating furnace body, a furnace door, and several gas burners distributed along the length direction of the heating furnace body. The gas burners include: an air intake pipe , the gas outlet pipe, the first circulation pipe, the second circulation pipe, both ends of the first circulation pipe and the second circulation pipe can be opened and closed, the regenerative combustion device arranged symmetrically outside the heating furnace body, the heat storage block, the heat storage container cavity, and a burner, the heat storage chamber is connected with the first circulation pipe and the second circulation pipe through a connecting pipe, the burner passes through the heating furnace body, the burner has a fuel port, an air port and an ejection port, and the heat storage chamber is connected with the heat storage chamber The fuel port of the burner is sealed and connected, the heat storage block is fixedly connected to the side of the fuel port of the burner, and the ejection port extends into the furnace of the heating furnace body, which solves the problem of low production efficiency caused by continuous heating in the heating furnace, and obtains Good energy saving, improved temperature uniformity, and reduced emissions.
Description
technical field [0001] The invention relates to the technical field of heating furnaces, in particular to an environmentally friendly heat storage trolley heat treatment furnace. Background technique [0002] The trolley heat treatment furnace has a movable trolley at the bottom of the furnace, and the heating front trolley is loaded outside the furnace. After the loading is completed, the trolley is pulled into the furnace by the traction mechanism for heating. After heating, the trolley is pulled by the traction mechanism. Unloading outside the furnace. Since there is only one trolley, the waiting time for work is long during loading and unloading, and the working efficiency of the heat treatment furnace is low, and during the loading and unloading process, the heat in the furnace body will leak out, resulting in a large heat loss. [0003] Chinese patent CN201410212828.3 provides a high-efficiency trolley heat treatment furnace. By setting two trolleys on the trolley tra...
