Abstract
The utility model relates to spray processing equipment, in particular to a special spraying flue gas furnace for increasing the furnace temperature uniformity. The special spraying flue gas furnace comprises a furnace body, and the bottom of the front end of the furnace body is provided with an outer air outlet to be connected with a circulating fan. The special spraying flue gas furnace is characterized in that a bottom plate, a front partition wall and a rear partition wall are arranged in the furnace body, and a space between the bottom plate and the front and rear partition walls and the inner wall of the furnace body forms a ventilation duct to be connected with the outer air outlet; the bottoms of the front and rear partition walls are respectively provided with 5-8 inner air inlets, and the inlet diameter of each inner air inlet is 200mm; a carrier plate is also arranged in the furnace body, and a space between the carrier plate and the top surface of the furnace body forms a heating cavity; 5 rows of air inlets are arranged in the carrier plate, the number of each row of air inlets is 5-8, and the inlet diameter of the air inlets is 200mm; the exhaust outlet of the circulating fan is communicated with the heating cavity through an air pipe; and the top of the furnace body over against the heating cavity is provided with a burner. The problem that the temperature difference in the current flue gas furnace is large is overcome, and the special spraying flue gas furnace is mainly used for heating casting spraying paint and workpieces before painting.
Description
(i) technical field: the utility model relates to spray process equipment, especially a kind of spraying Special smoke steam stove that improves temperature homogeneity in stove.
(ii) background technology: be typically designed to for the combustion gas furnace on the spray process production line version that the flue gas side advances, side goes out at present, and generally be designed with two air inlets and two air outlets, both bores are respectively 300mm and 400mm, existing this structural design is very unreasonable, heat exchange occurs in the stove inboard, in stove, temperature is very inhomogeneous, often the workpiece two ends temperature difference of heating can reach 20 ℃, the utmost point is unfavorable for later stage sprayed coating and paint on workpiece, easily causes producing the problems such as pore, paint film is inhomogeneous, color is inconsistent after Workpiece painting.
(iii) utility model content: the purpose of this utility model will solve non-uniform temperature in existing combustion gas furnace stove exactly, is unfavorable for the problem of later stage sprayed coating and paint on workpiece, and a kind of spraying Special smoke steam stove that improves temperature homogeneity in stove is provided.
Concrete scheme of the present utility model is: for the existing Special smoke steam stove that sprays paint, transformed, it has body of heater, the front bottom end of body of heater is provided with outer air outlet and connects circulating fan, it is characterized in that: be provided with base plate and front and back partition wall in body of heater, between base plate and front and back partition wall and inboard wall of furnace body, there is spacing to form ventilating duct and be connected outer air outlet, respectively offer air outlet in 5-8 in front and back partition wall bottom, in each, the bore of air outlet is 200mm, also be provided with top board in body of heater, between the end face of top board and body of heater, there is spacing to form heating chamber, and have 5 rows on top board, 5-8 air inlet of every row, the air inlet bore is 200mm, the exhaust outlet of described circulating fan is communicated with heating chamber by airduct, and over against heating chamber, burner is installed at the body of heater top.
Burner described in the utility model is mounted in the center at body of heater top.
The port of export of airduct described in the utility model is positioned at the body of heater top, near burner or front or rear 200mm place, arranges.
It is 12000m that circulating fan described in the utility model is selected air quantity
3The blower fan of/h.
In the utility model, make heat exchange change the stove internal upper part into by a side in stove, and increased air inlet quantity, reduced the air inlet bore, increased exhaust outlet quantity, reduced the exhaust outlet bore.Increase the draft of circulating fan (air quantity is by 8000 original m simultaneously
3/ h brings up to 12000 m
3/ h), greatly improved the temperature homogeneity at heated parts two ends in the combustion gas furnace stove, the temperature difference at workpiece two ends can be controlled in 2 ℃ of left and right, thoroughly solved because the two ends temperature difference after the workpiece heating is large, easily caused the problems such as Workpiece painting coating or paint produce pore, paint film is inhomogeneous, color is inconsistent.
(iv) accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A schematic diagram of Fig. 1.
