DETAILED DESCRIPTION

[0024] Example:

[0025] The following is combined with Figure 1-3 The utility model is described in further detail.

[0026] Dumbbell mesh belt sintering furnace, such as Figure 2 As shown, the furnace body 10 is divided into a feeding section 20, a preheating section 30, a heating section 40, a heat preservation section 50 and a discharging section 60 from front to back, that is, the order of discus transmission. A continuously circulating conveyor mesh belt 13 is provided in the furnace body 10. The conveyor mesh belt 13 passes through the above functional sections in sequence and is led to a correction unit 70 additionally arranged near the discharging section 60, and finally leads back to the feeding section 20 to form a closed-loop conveyor belt structure. Figure 1 As shown, the head end of the feeding section 20 is provided with a protruding feeding cavity 21, the end of the discharging section 60 is provided with a protruding discharging cavity 61, the end of the discharging section 60 is connected with a buffer table 90, and notches are sawed at the corners of the buffer table 90 to facilitate the end shaft setting of the conveyor mesh belt 13, and a buffer groove starts on the buffer table 90, and a guide turn plate 91 is provided on the periphery of the buffer groove, and the guide turn plate 91 is aligned with the outlet of the discharging cavity 61. The furnace body 10 is equipped with a special air duct 11. Continuous heating units 12 are provided on the furnace body 10 in the preheating section 30, the heating section 40 and the insulation section 50. Preferably, the air duct 11 is connected to the feed chamber 21 and the discharge chamber 61 to avoid the influence on the temperature and uniformity inside the furnace body 10 during the preheating, heating and insulation stages. The air ducts 11 at the two locations are connected to the ventilation system in the factory for centralized discharge, mainly the gas generated by the combustion of the heating unit 12 and the waste gas generated by the heating of the discus, etc., and an activated carbon adsorption and other tail gas treatment devices are added.

[0027] The purpose of setting a deviation correction structure on the conveyor belt structure is to prevent the conveyor belt 13 from deviating during the transmission process, which would cause adverse effects on the heating of the discus, such as uneven heating, transmission stagnation, etc. Figure 3As shown, the structure of the deviation correction unit 70 is improved, a stepped structure is added at the rear end, and a cleaning unit 80 is installed. The cleaning unit 80 includes a rinse seat 81, a fixed brush roller 83, a tensioning grinding roller 85 and a liquid collecting tray 87. A rinse seat 81 is installed at the bottom of the front end of the deviation correction unit 70, and a concave arc groove 82 is provided on the top of the rinse seat 81. The arc groove 82 is filled with a cleaning lubricant with a suitable liquid level height, and it is necessary to ensure that the contact surface of the transmission mesh belt can contact the liquid surface for lubrication and cleaning. Considering that the contact between the transmission mesh belt 13 and the cleaning lubricant will cause the liquid level to rise, there is a risk of overflow and waste, an upwardly tilted and covered liquid collecting tray 87 is added to the bottom of the rinse seat 81, and the top of the liquid collecting tray 87 needs to be lower than the top of the rinse seat 81 to avoid hindering the movement of the transmission mesh belt. A fixed brush roller 83 is provided in the middle section of the deviation correction unit 70. The fixed brush roller 83 does not rotate. A scraping brush 84 is provided on the top of the fixed brush roller 83. The scraping brush 84 can be drawn out from the rinse seat 81 and passed through the fixed brush roller 83 to scrape and clean the contact surface of the rinsed conveyor mesh belt 13 to remove some residual debris. A tensioning grinding roller 85 is installed at the added step structure. The tensioning grinding roller 85 is rotatably connected to the deviation correction unit 70. A grinding sleeve 86 is provided on the roller body. The grinding sleeve 86 is a layer of sanding sleeve covering the surface of the tensioning grinding roller 85. It also has a certain liquid absorption performance. The conveyor mesh belt is polished and liquid is absorbed, and the tension of the deviation correction unit 70 is strengthened. The setting heights of the rinse seat 81, the fixed brush roller 83, and the tensioning grinding roller 85 are increased in sequence. The conveyor mesh belt 13 is introduced from the rinse seat 81, passes through the fixed brush roller 83 and the tensioning grinding roller 85, and is tensioned and drawn out.

[0028] The discus enters from the feeding section 20 , is initially heated up in the preheating section 30 and then is transferred, is concentratedly heated up in the heating section 40 , and is transferred to the insulation section 50 for insulation for a certain period of time, is transferred out from the discharging section 60 , and is temporarily stored on the buffer table 90 through the guide turn plate 91 .

[0029] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
