First embodiment:
fig. 1-2 show a first embodiment of the utility model, a waste heat utilization oven for a profile powder spray line, comprising a conveyor tunnel 1, a burner 2, a first suction fan 3, a sludge drying box 4. An inlet 211 of the combustion furnace is connected with an outlet of the conveying tunnel 1, and a first exhaust fan 3 is connected at an outlet 212 of the combustion furnace; the first exhaust fan 3 and the sludge drying box 4 are connected in sequence according to the flow direction of hot air; the sludge drying box 4 is used for loading and baking the sludge filtered in other working procedures of the workshop.
In operation, the combustion furnace 2 burns a combustible gas to produce hot gas, which toasts the profile (i.e. the workpiece) suspended from the chain 7, typically at a temperature of around 200 ℃ to promote the solidification reaction of the powder. The baked work piece is slowly sent out by a chain 7, dried in the air and packaged. The waste heat utilization type oven for the profile powder spraying line sucks the hot gas escaping from the outlet 212 of the combustion furnace to the sludge drying box 4 through the first exhaust fan 3, so that the sludge drying box 4 can bake and dehumidify sludge generated by filtering in other working procedures of the workshop, and the phenomenon that the sludge drops onto the workshop to pollute the workshop is avoided. In this way, the hot gas escaping into the workshop is also greatly reduced, so that the temperature of the workshop is not greatly increased. The sludge drying box 4 is responsible for continuously feeding wet sludge and discharging dried sludge by a worker.
Obviously, locate the export 212 of burning furnace through first air exhauster 3, and first air exhauster 3, mud stoving case 4 are connected according to the flow direction of steam in proper order to make first air exhauster 3 can be with the hot gas suction that fires in the burning furnace overflow to mud stoving case 4, in order to dry the wet mud that the workshop produced, and then avoid wet sludge dripping to the workshop, and make the phenomenon that the workshop was polluted. Meanwhile, the wet sludge is dried without adding another heat source, so that the waste heat is fully utilized, and the energy consumption is reduced.
Preferably, the channel of the burner 2 has a U-shaped structure, the opening 21 of the burner 2 is engaged with the outlet of the delivery tunnel 1, and the first side wall 11 of the delivery tunnel 1 is connected to the side wall of the burner 2, and the second side wall 12 of the delivery tunnel 1 is located between the opposite side walls of the burner 2, so as to divide the opening 21 of the burner 2 into an inlet 211 of the burner and an outlet 212 of the burner. By the arrangement, the length of the combustion furnace 2 can be reduced as much as possible, and the heated length of the chain 7 is prolonged, so that the workpiece can be sufficiently baked, and the curing reaction of the workpiece is ensured to be more thorough. More preferably, referring to fig. 2, the section of the burner 2 close to the transport tunnel 1 (i.e. the whole section or a certain section) is in an inclined configuration, the height of which gradually increases in a direction away from the transport tunnel 1. The arrangement is based on the fact that the density of the hot gas is low, the hot gas tends to rise, so that the hot gas is more easily gathered at the top of the combustion furnace 2, the gas with higher temperature is always positioned at the top of the combustion furnace 2, a workpiece is baked by the gas with high temperature, and the gas with lower temperature is sucked by the negative pressure of the first exhaust fan 3 and enters the sludge drying box 4; in this way, the hot gas is more difficult to escape to the workshop, and the temperature rise phenomenon of the workshop is better eliminated.
Preferably, the waste heat utilization type oven for the profile powder spraying line further comprises a water spray tower 51, a UV photolysis purifier 52 and an activated carbon adsorption tower 53; the first exhaust fan 3, the sludge drying box 4, the water spray tower 51, the UV photolysis purifier 52 and the activated carbon adsorption tower 53 are sequentially connected according to the flow direction of hot air. The waste gas treated by the water spray tower 51, the UV photolysis purifier 52 and the active carbon adsorption tower 53 accords with the environmental protection standard.
More preferably, in order to facilitate purification of the exhaust gas by the activated carbon adsorption tower 53, the outlet of the activated carbon adsorption tower 53 is connected with a second exhaust fan 54.

Second embodiment:
fig. 3 to 4 show a waste heat utilization type oven for a profile powder spray line according to a second embodiment of the present utility model, which includes a first embodiment, which is different from the first embodiment in that: the passage of the burner 2 is of a linear configuration so that the burner inlet 211 and burner outlet 212 are located at opposite ends of the burner 2; and the level of the outlet 212 of the burner is lower than the level of the middle of the burner 2. So arranged, the chain 7 does not need to turn, but rather there is a submerged section. So arranged, the density of the hot gas is low, so that the hot gas is accumulated in the middle of the combustion furnace 2, and the gas with lower temperature is sucked by the negative pressure of the first exhaust fan 3 and enters the sludge drying box 4 in the same manner as the first embodiment; the advantage of this is that the channels of the burner 2 can be set narrower to meet the spatial layout of the environment. More preferably, the inlet 211 of the burner has a lower level than the middle of the burner 2; this allows the burner 2 to be placed on the ground without having to set the burner inlet 211 in a suspended state to better meet the actual site utilization requirements.
