The technical scheme of the utility model is as follows:
in order to achieve the above purpose, the utility model is realized by the following technical scheme: the furnace comprises a furnace table, wherein the left side of the furnace table is provided with a furnace door, the upper surface of the furnace table is provided with a furnace wall, a semi-closed heating furnace chamber is formed among the furnace door, the furnace wall and the furnace table, a plurality of burners communicated with the furnace chamber are arranged on the furnace wall along the length direction, one end of the furnace wall, far away from the furnace door, is connected with a flue, and the junction of the furnace table and the furnace wall is provided with a communication channel communicated with the area near the furnace door and the bottom of the flue.
Optionally, the two communication channels are symmetrically arranged front and back.
Optionally, a plurality of vent holes are arranged on the stove table, and the vent holes are communicated with the communication channels.
Optionally, the distance between two adjacent ventilation holes gradually increases from the left side to the right side of the stove table.
Optionally, a chimney is arranged at the outlet of the upper end of the flue.
Advantageous effects
The utility model provides a drainage structure of a chamber type natural gas heating furnace, which has the following beneficial effects:
according to the drainage structure of the chamber type natural gas heating furnace, the communicating channel for communicating the area near the furnace door of the heating furnace with the bottom of the flue is formed at the junction of the furnace table and the furnace wall, and the arrangement of the chimney strengthens the convection circulation of air in the furnace, so that the technical effects of improving the uniformity of the furnace temperature of the heating furnace and the precision of processing workpieces can be realized.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a left side view of fig. 1 in accordance with the present utility model.
In fig. 1-2, the furnace comprises a furnace table 1, a furnace door 2, a furnace wall 3, a furnace chamber 4, a burner 5, a flue 6, a communication channel 7, a vent hole 8, a chimney 9 and the like.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1 to 2, the present utility model provides a technical solution: a drainage structure of a chamber type natural gas heating furnace comprises: including stove top 1, stove top 1 left side is provided with furnace gate 2, and stove top 1 upper surface is provided with furnace wall 3, constitutes semi-closed heating furnace chamber 4 between furnace gate 2, furnace wall 3 and the stove top 1, is provided with a plurality of nozzles 5 of intercommunication furnace chamber 4 along length direction on the furnace wall 3, and furnace wall 3 keeps away from furnace gate 2 one end bottom and connects flue 6, and stove top 1 and furnace wall 3 juncture is provided with the intercommunication passageway 7 of the nearby region of intercommunication furnace gate 2 and flue 6 bottom.
The two communication channels 7 are arranged in a front-back symmetrical mode, can work simultaneously, and can discharge flue gas generated in front of and behind the heating furnace simultaneously.
The stove table 1 is provided with a plurality of vent holes 8, the vent holes 8 are communicated with the communication channel 7, and the vent holes can be used for discharging smoke at the same time, so that the smoke discharging efficiency is improved.
The distance between two adjacent vent holes 8 gradually increases from the left side to the right side of the hearth, and the left side hearth area is easy to generate an air flow dead zone, and accumulated air is more, so that the vent holes are arranged more, and the smoke discharging effect of the area is improved.
