[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] The utility model provides Figure 1-5 The box-type furnace with a sagger and a fume treatment system shown includes a box-type furnace body 2 and a drive system 1 installed on the right side of the box-type furnace body 2;
[0028] A plurality of sagger bodies 6 are arranged inside the box-type furnace body 2;
[0029] An incinerator 10 is provided on the upper side of the box-type furnace body 2 to incinerate the gas and tar generated by the sintering material inside the box-type furnace body 2;
[0030] An exhaust fan 5 is provided on the left side of the incinerator 10 to discharge the gas generated during the incineration of the incinerator 10 to the outside, and an exhaust pipe 11 is provided between the incinerator 10 and the exhaust fan 5 to guide the gas generated by the incineration to the exhaust fan 5. First, the driving system 1 conveys the sagger body 6 to automatically enter and exit the box-type furnace main body 2 and incinerate it. The gas and tar produced by the incineration of the sintered material are guided into the incinerator 10. The incinerated sagger body 6 is pushed out by the driving system 1, and the unburned sagger body 6 is introduced for incineration. During the incineration process, the gas and tar are incinerated, and then the exhaust gas generated after the incineration is discharged from the exhaust fan 5 to the outside through the exhaust pipe 11;
[0031] An inner frame 24 is provided at the air outlet position on the upper side of the exhaust fan 5, and a plurality of dust collecting cloths 16 are equidistantly provided inside the inner frame 24 to block particulate matter in the exhaust gas. Activated carbon particles 21 are provided inside the inner frame 24 near the upper side to remove harmful components in the adsorbed gas and tar and volatile organic compounds generated during the incineration process. When the exhaust fan 5 discharges the exhaust gas to the outside, the particulate matter in the gas is blocked by the dust collecting cloth 16, and then the gas flows through the activated carbon particles 21 to remove harmful components in the adsorbed gas and tar and volatile organic compounds generated during the incineration process. The negative impact of the exhaust gas is reduced through double filtration of the dust collecting cloth 16 and the activated carbon particles 21.
[0032] like Figure 4 As shown, a filter 15 is fixedly connected between the inner walls of the left and right ends of the inner frame 24 near the upper side, a net bag 22 is provided on the upper side of the filter 15 to accommodate the activated carbon particles 21, and a plurality of dust collecting cloths 16 are provided with support rods 17 on the lower sides to limit the position of the dust collecting cloths 16, and connecting rods 23 are fixedly connected between the plurality of support rods 17 and the inner frame 24 to limit the position of the support rods 17.
[0033] The filter 15 supports the net bag 22 containing the activated carbon particles 21 and limits the position of the activated carbon particles 21. The activated carbon particles 21 of different sizes are accumulated inside the net bag 22. When installing the dust collecting cloth 16, the dust collecting cloth 16 can be placed on the supporting rod 17.
[0034] like Figure 4 and Figure 5 As shown, a fixing plate 19 is fixedly connected to the upper air outlet position of the exhaust fan 5, and an outer frame 20 is clamped on the upper side of the fixing plate 19 to limit the position of the inner frame 24. The lower outer wall of the outer frame 20 is fixedly connected to a block 18 that penetrates downward into the fixing plate 19 to limit the interior of the outer frame 20. A slot for the block 18 to be clamped is provided inside the upper outer wall of the fixing plate 19. The inner frame 24 is through-through and open on the front side. A through hole is opened inside the center of the fixing plate 19 for gas to enter the interior of the inner frame 24.
[0035] The mounting position of the outer frame 20 is provided by the fixing plate 19, and the interior of the outer frame 20 can be restricted by locking the block 18 at the lower end of the outer frame 20 and the fixing plate 19. When the dust collecting cloth 16 and the activated carbon particles 21 need to be cleaned or replaced, the inner frame 24 is pulled out from the outer frame 20, and then the corresponding dust collecting cloth 16 and the activated carbon particles 21 are taken out through the opening of the inner frame 24 for cleaning or replacement. The replaced dust collecting cloth 16 is replaced on the staggered support rods 17 to block the particulate matter in the exhaust gas without limiting the speed of exhaust gas circulation.
[0036] like Figure 2 and Figure 3 As shown, a conveyor belt 3 is provided inside the box-type furnace body 2 to drive the sagger body 6 to move, and an air intake pipe 13 is fixedly connected to the front end outer wall of the incinerator 10 to transport oxygen to the inside of the incinerator 10. An oil outlet pipe 8 is fixedly connected to the front end outer wall of the incinerator 10 to guide the tar outward into the incinerator 10, and an oil drain valve 9 is fixedly connected to the other end of the oil outlet pipe 8 to discharge the tar from the oil outlet pipe 8.
[0037] The drive system 1 moves by driving the conveyor belt 3 to complete the entry and exit management of the sagger body 6. When combustion is occurring inside the incinerator 10, the air required for combustion is sucked into the incinerator 10 through the air intake pipe 13. The gas and tar generated by the sintering material of the box-type furnace body 2 can be guided into the incinerator 10 through the oil outlet pipe 8. The tar that cannot be introduced into the incinerator 10 can be accumulated on the lower side of the oil outlet pipe 8, and the tar can be discharged for secondary treatment by opening the oil drain valve 9.
[0038] like Figure 2 and Figure 3 As shown, a temperature measuring thermocouple 14 is fixedly connected to the outer wall of the upper end of the exhaust pipe 11 near the exhaust fan 5 to detect the temperature of the exhausted exhaust gas. A platform 4 is provided on the upper side of the box-type furnace body 2 to limit the position of the incinerator 10. A nitrogen fire extinguishing system 12 is provided on the front side of the incinerator 10. A ladder 7 is fixedly connected to the outer wall of the right end of the platform 4 for staff to climb onto the platform 4.
[0039] The temperature of the exhaust gas in the exhaust pipe 11 can be detected by the temperature measuring thermocouple 14. If the temperature exceeds the standard, the wind speed of the exhaust fan 5 is controlled to be reduced to slow down the discharge speed of the hot gas. When the temperature returns to normal, the exhaust fan 5 is controlled to return to the normal wind speed for exhaust operation. Through the nitrogen fire extinguishing system 12, nitrogen can be sprayed into the incinerator 10 for fire extinguishing operation when there is no need for combustion inside the incinerator 10. The staff can climb onto the platform 4 through the ladder 7 to perform maintenance and cleaning work.
[0040] The principle of the embodiment is that: firstly, the driving system 1 conveys the sagger main body 6 to automatically enter and exit the box furnace main body 2, and performs incineration; the gas and tar produced by incineration of sintered materials are guided to the incinerator 10; the sagger main body 6 after incineration is pushed out by the driving system 1; the sagger main body 6 which is not incinerated is introduced to perform incineration; in the incineration process, the gas and tar are incinerated; then the exhaust gas produced after incineration is discharged from the exhaust fan 5 through the exhaust pipeline 11; when the exhaust fan 5 discharges the exhaust gas, the particulate matters in the gas are blocked by the dust collecting cloth 16; then the harmful components in the adsorbed gas, the tar and volatile organic compounds produced in the incineration process are removed by flowing through the activated carbon particles 21; the exhaust gas is double-filtered by the dust collecting cloth 16 and the activated carbon particles 21, so that the negative influence of the exhaust gas is reduced.
[0041] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
