[0033] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] As Figures 1 - 5 shown, an embodiment of the present utility model provides a smoke exhaust device for a foaming furnace, including a furnace body 1. Along the length direction of the furnace body 1, the furnace body 1 has an inlet end, a cavity, and an outlet end that are sequentially connected. A conveying assembly for conveying foaming products is arranged in the cavity. A first through hole 2 and a second through hole 3 are opened on the side wall of the cavity near the outlet end. The conveying assembly is located between the first through hole 2 and the second through hole 3. The first through hole 2 and the second through hole 3 are connected through a connecting air duct 12;

[0035] A regulating assembly 4 is arranged at the bottom of the conveying assembly. The regulating assembly 4 is used for regulating the amount of oil fume entering the second through hole 3;

[0036] A smoke exhaust pipe 5 for connecting a waste extraction pipe is arranged at the top of the furnace body 1. The first through hole 2 is connected to the smoke exhaust pipe 5.

[0037] When the foaming product is plate-shaped, the oil fume above the foaming product in the cavity of the furnace body 1 is directly discharged through the smoke exhaust pipe 5, and the oil fume below the foaming product flows out through the second through hole 3, enters the first through hole 2 after passing through the connecting air duct 12, and is then sucked into the waste extraction pipe through the smoke exhaust pipe 5 connected to the waste extraction pipe. Therefore, the oil fume can be timely sucked into the smoke exhaust pipe 5, and it is not easy for the oil fume to overflow from the furnace body 1, protecting the environment. And because the oil fume has been timely discharged into the smoke exhaust pipe 5 in the furnace body 1, therefore, there is no need to add an additional smoke exhaust furnace at the outlet end of the foaming furnace discharging section for smoke exhaust, reducing the production cost.

[0038] Furthermore, the first through-hole 2 and the second through-hole 3 are respectively located on two opposite side walls of the foaming furnace. Two connecting air ducts 12 can be provided, and the connecting air ducts 12, the first through-hole 2, and the second through-hole 3 correspond to each other one by one.

[0039] According to an embodiment of the present invention, an upper tile plate and a first oil pan 6 are arranged in the furnace body 1. The first oil pan 6 is arranged below the smoke exhaust pipe 5. Both the first oil pan 6 and the upper tile plate are connected to the furnace body 1. A connecting plate 7 is connected to the side of the upper tile plate close to the first oil pan 6. An air inlet is formed between the connecting plate 7 and the first oil pan 6. The cavity of the furnace body 1 is communicated with the smoke exhaust pipe 5 through the air inlet.

[0040] The top of the connecting plate 7 is fixedly connected to the top wall of the cavity, and the bottom is fixedly connected to the upper tile plate.

[0041] One end of the air inlet close to the top wall of the furnace body 1 has a small opening, and the other end has a large opening, which can play a role in guiding the oil fume.

[0042] By providing the first oil pan 6, the oil droplets formed after the oil fume entering the smoke exhaust pipe 5 from the cavity of the furnace body 1 through the air inlet condenses can fall onto the first oil pan 6, preventing the oil droplets condensed by cooling from contaminating the foaming product and improving the quality of the foaming product.

[0043] According to an embodiment of the present invention, the first oil pan 6 includes a connected first plate body and second plate body. The first plate body is located between the second plate body and the connecting plate 7. One side of the first plate body close to the second plate body is lower than the other side.

[0044] Among them, the first plate body is directly below the smoke exhaust pipe 5. When the oil droplets condensed from the cold oil fume in the smoke exhaust pipe 5 fall onto the first plate body under the action of gravity, since one side of the first plate body close to the second plate body is lower than the other side and is inclined, the accumulated oil droplets can slowly fall onto the second plate body, which is convenient for cleaning and can prevent the situation that too much oil droplets accumulate on the first plate body, resulting in a reduction in the amount of inhaled oil fume.

[0045] According to an embodiment of the present invention, a second oil pan 15 is connected to the bottom of the connecting plate 7, and a baffle is provided on the side of the second oil pan 15 away from the connecting plate 7.

[0046] By providing the second oil pan 15, the oil droplets condensed from the cold oil and attached to the connecting plate 7 passing through the air inlet can be caught, preventing them from slipping off the connecting plate 7 and contaminating the foaming product, and thus improving the quality of the foaming product.

[0047] By providing the baffle, it can prevent the oil droplets from accumulating too much and dripping from the second oil pan 15.

A first stop bar 401 and a second stop bar 402 are respectively arranged on both sides of the notch 403. The second stop bar 402 is connected to the rectangular frame. The first stop bar 401 is connected to the first adjustment plate 404. The first adjustment plate 404 is installed at the notch 403 through the adjustment structure, and the adjustment structure is used to adjust the distance between the first stop bar 401 and the second stop bar 402.

[0050] Through the notch 403 opened on the rectangular frame, the oil fume located below the foaming product or the conveying assembly can be sucked into the collection cavity, enter the second through hole 3 through the collection cavity, and finally be sucked into the smoke exhaust pipe 5 through the connecting air duct 12 and the first through hole 2. And because the rectangular frame is provided and the rectangular frame is arranged near the outlet end of the foaming furnace discharging section, therefore, the oil fume that is about to overflow from the outlet end can be absorbed specifically, and the ability to prevent the oil fume from overflowing is stronger and the effect is better.

[0051] By changing the adjustment structure to change the position of the first adjustment plate 404, the distance between the first stop bar 401 and the second stop bar 402 can be adjusted, and then the size of the notch 403 can be changed, so as to adjust the amount of oil fume entering the collection cavity.
