Description

Technical Field

[0001] The utility model relates to the technical field of foaming devices, in particular to a fume exhaust device for a foaming furnace and a foaming device. Background Art

[0002] In the production process of foam pads, the mesh needs to be fed into a foaming furnace for foaming after being coated with slurry. During the foaming process, a large amount of oily fume exhaust gas will be generated. These exhaust gases contain a large amount of heat. If they are not removed in time, they are prone to combustion or explosion, resulting in safety accidents. In the prior art, a smoke exhaust pipe is usually set at the top of the foaming furnace, and the high-temperature exhaust gas in the furnace body is extracted by the exhaust fan, which can easily avoid safety hazards. However, since the foaming furnace usually heats the foam pad by blowing hot air, if the exhaust gas extraction speed is too fast, the temperature in the furnace body will drop, and the amount of hot air blowing will need to be increased, resulting in increased energy consumption; and when the exhaust speed is too slow, high-temperature exhaust gas will accumulate, resulting in internal combustion, which poses a safety hazard. It can be seen that the prior art needs to be improved and enhanced. Utility Model Content

DETAILED DESCRIPTION

[0018] The utility model provides a fume exhaust device for a foaming furnace and a foaming device. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] See also Figure 1 and Figure 2The first aspect of the utility model provides a foaming furnace smoke exhaust device, which is used for outputting exhaust gas in the foaming furnace. The device includes a plurality of smoke exhaust pipes 1 arranged on the top of the foaming furnace and a smoke exhaust channel 2 connected to the plurality of smoke exhaust pipes 1, an exhaust fan 3 arranged at the output end of the smoke exhaust channel 2, and a plurality of first temperature sensors 4 arranged in the smoke exhaust channel 2, and also includes a control mechanism 5 and an alarm mechanism 6. Among them, multiple smoke exhaust pipes 1 are arranged on the top of the foaming furnace and distributed in various areas of the foaming furnace (it should be noted here that the foaming furnace needs to be provided with multiple foaming areas according to the foaming temperature. Generally speaking, there are five areas, and the temperature of each area is different, so that the cushion body to be foamed can be gradually preheated, plasticized, and foamed). Each foaming area is provided with at least two smoke exhaust pipes 1. Since the exhaust gas generated in each foaming area is different, the amount of exhaust gas generated is also different. More exhaust pipes can be set for areas with more exhaust gas generation, so as to timely guide the exhaust gas generated in each area of ​​the foaming furnace to the smoke exhaust channel 2; the smoke exhaust channel 2 is provided with a corresponding smoke exhaust area for each foaming area, and the smoke exhaust channel 2 is connected to the exhaust gas treatment device, and an exhaust fan 3 is provided at its output end. for conveying the exhaust gas to the exhaust gas treatment device; multiple first temperature sensors 4 are arranged in each exhaust area of ​​the exhaust channel 2, for monitoring the exhaust gas temperature of each exhaust area; the control mechanism 5 is electrically connected to the first temperature sensor 4, the exhaust fan 3 and the alarm mechanism 6 respectively, for receiving the temperature information obtained by the first temperature sensor 4, and adjusting the power of the exhaust fan 3 and issuing an alarm prompt according to the temperature information. The control mechanism 5 can also set the temperature limit of each exhaust area, such as setting an upper and lower temperature limit for each exhaust area, and setting an alarm prompt limit to avoid combustion due to overheating of the exhaust gas temperature. At the same time, the control mechanism 5 can also adjust the power of the exhaust fan 3 according to the temperature of each exhaust area to avoid combustion due to excessively high exhaust gas temperature.

[0020] During the specific production process, the exhaust fan 3 is used to draw the waste gas in the foaming furnace through the exhaust pipe 1 into the exhaust channel 2, and then transported to the waste gas treatment device through the exhaust channel 2 for treatment. When the waste gas enters the exhaust channel 2, multiple first temperature sensors 4 can monitor the temperature of the exhaust area in real time. When the temperature of any exhaust area exceeds the temperature limit of the area, the alarm mechanism 6 issues an alarm. At the same time, the exhaust fan 3 will increase the power to quickly draw away the waste gas, so as to reduce the temperature of the exhaust channel 2 and avoid the occurrence of fire.

[0021] Although the temperature of each area of ​​the smoke exhaust channel 2 can be monitored by the first temperature sensor 4 and an alarm can be given in time, a fire is still likely to occur when the heat carried by the exhaust gas is too high. In this regard, in a preferred embodiment, the device is also provided with a spray mechanism 7, which is arranged in the smoke exhaust channel 2, and includes a water pipe 8 and a plurality of nozzles 9, and an electric control valve 10 for controlling the switch of the nozzle 9, and the electric control valve 10 is electrically connected to the control mechanism 5. During the specific implementation process, multiple temperature limits can be set for each smoke exhaust area through the control mechanism 5, for example, a first temperature limit, a second temperature limit, and a third temperature limit are set for each smoke exhaust area, and the temperatures are ranked as follows: first temperature limit < second temperature limit < third temperature limit. When the temperature acquired by the corresponding first temperature sensor 4 reaches or exceeds the first temperature limit, the alarm mechanism 6 issues an alarm prompt, and at the same time the power of the exhaust fan 3 is increased (the specific increase can be set according to actual needs); when the temperature acquired by the corresponding first temperature sensor 4 reaches or exceeds the second temperature limit, the alarm mechanism 6 issues an alarm prompt, and at the same time the spray mechanism 7 is started to spray water mist, and the water mist is used to cool down and avoid fire; when the temperature acquired by the corresponding first temperature sensor 4 reaches or exceeds the third temperature limit, the alarm mechanism 6 continues to alarm, the spray mechanism 7 sprays water mist, and at the same time, the foaming furnace is shut down to prevent the foaming furnace from continuing to heat and produce more exhaust gas, which may cause safety hazards.

[0022] In order to quickly drain the water sprayed by the spray mechanism 7 so as to quickly cool down, the smoke exhaust channel 2 is also connected to a drain pipe 11, which can drain the water in time.

[0023] In order to prevent the water mist from entering the foaming furnace through the smoke exhaust pipe 1 when spraying water mist, in a preferred embodiment, the top of the smoke exhaust pipe 1 extends into the smoke exhaust channel 2, and a waterproof cover 12 is provided on the top thereof, so that when spraying water mist, water will not flow into the foaming furnace.

[0024] Generally speaking, the exhaust gas generated by the foaming furnace contains a large amount of heat, so it will gather on the top of the foaming furnace. If the pipe mouth 13 of the smoke exhaust pipe 1 is located on the top surface of the foaming furnace, it can quickly discharge the exhaust gas, but at the same time it will also quickly take away the heat in the foaming furnace, resulting in increased energy consumption of the foaming furnace. In this regard, in a preferred embodiment, the lower end of the smoke exhaust pipe 1 extends into the foaming furnace, and the position height of the pipe mouth 13 is flush with or lower than the position height of the cushion to be foamed. Therefore, when the exhaust gas is extracted through the smoke exhaust pipe 1, the exhaust gas must first pass through the cushion to be foamed and then enter the smoke exhaust pipe 1, so that the heat contained in the exhaust gas can be utilized, thereby reducing the energy consumption of the foaming furnace.

[0025] The second aspect of the utility model also discloses a foaming device, such as Figure 1As shown, the foaming device includes a foaming furnace and a smoke exhaust device; the foaming furnace includes a furnace body 14, a conveying mechanism 15 and a heating mechanism 16 arranged in the furnace body 14, the furnace body 14 is provided with a plurality of foaming areas, each foaming area has a different temperature, which can be specifically set according to actual needs; the conveying mechanism 15 is used to convey the cushion body to be foamed; the heating mechanism 16 is provided with a plurality of, which are respectively located above and below the conveying mechanism 15, and are used to heat the cushion body to be foamed; the smoke exhaust device is the foaming furnace smoke exhaust device as described above, which is used to discharge the exhaust gas generated during foaming.

[0026] In a preferred embodiment, the heating mechanism 16 includes an air hood 17, an electric heating wire 18 arranged in the air hood 17, and an air pump 19 connected to the air hood 17. The air pump 19 and the electric heating wire 18 are electrically connected to the control mechanism 5, and the switch and power adjustment of the air pump 19 and the electric heating can be controlled by the control mechanism 5.

[0027] In a preferred embodiment, the furnace body 14 is further provided with a plurality of second temperature sensors 20 , which are distributed in each foaming area of ​​the furnace body 14 and electrically connected to the control mechanism 5 for obtaining the temperature of each foaming area in the furnace body 14 .

[0028] During operation, the temperature threshold of each foaming area can be set according to the control mechanism 5, and the temperature information of each foaming area can be obtained through the second temperature sensor 20. When the temperature of each foaming area is within the temperature threshold, the air pump 19 and the electric heating wire 18 work at the set power. When the temperature exceeds the upper limit or is lower than the lower limit, the power of the air pump 19 and the electric heating wire 18 is adjusted to make the temperature of each area within the set temperature threshold to ensure the foaming quality.

[0029] In summary, the foaming furnace exhaust device provided by the utility model can monitor the temperature of each exhaust area of ​​the exhaust channel 2 in real time by setting the control mechanism 5, the first temperature sensor 4 and the alarm mechanism 6, and give an alarm prompt according to the information obtained by the first temperature sensor 4, so it is safer; through the spray mechanism 7, water mist can be sprayed to cool down when the temperature of each exhaust area exceeds the set limit, so as to avoid the combustion or explosion of exhaust gas, which is safer. The foaming device using the exhaust device can better exhaust the exhaust gas and has higher safety.
