Description

Technical Field

[0001] The utility model relates to the technical field of biological sponge processing, in particular to a drying tunnel structure for biological sponge production. Background Art

[0002] A sponge is a porous material that has good water absorption and can be used to clean items. It can be natural or artificial. Artificial sponges are made of wood cellulose fibers, foamed plastic polymers or other synthetic materials. Common ones include PU sponges, recycled sponges, etc.

[0003] During the sponge production process, foaming needs to be carried out in a drying oven, and a certain amount of heat is provided to the drying oven to maintain a constant temperature. The existing drying oven increases the temperature inside the drying oven by installing a heating block inside the drying oven. The heating block heats the sponge in the drying oven unevenly, resulting in uneven density of the sponge, thereby reducing the quality of the sponge. Utility Model Content

[0004] The utility model discloses a drying tunnel structure for producing biological sponges, aiming to solve the technical problem that the temperature in the existing drying tunnel is increased by installing a heating block inside the drying tunnel, the heating block is used to heat the sponge in the drying tunnel unevenly, resulting in uneven density of the sponge, thereby reducing the quality of the sponge.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A conveying mechanism, used for conveying the sponge body;

[0008] The heating mechanism comprises a heater arranged on the top of the drying oven, the input end of the heater is connected to a circulation pipe, the end of the drying oven away from the heater is provided with a return air pipe, one end of the circulation pipe is fixedly connected to the return air pipe, the output end of the heater is provided with an air supply pipe, one end of the air supply pipe is arranged in the drying oven.

[0009] In this solution, the heater blows hot air into the drying oven through the air supply pipe, heats the air and then blows it into the drying oven. The hot air flows in the drying oven and contacts the sponge body, and transfers the heat to the sponge body through heat conduction and convection heat transfer, so that the sponge body is foamed and dried at a suitable temperature. The hot air in the drying oven flows back into the circulation pipe from the return air pipe at one end of the drying oven, and then enters the drying oven through the air supply pipe. The hot air circulation method is adopted to reduce heat loss, ensure that the surface of the sponge body is evenly heated, and improve the drying efficiency.

[0010] In a preferred embodiment, the transport mechanism includes a conveyor belt arranged on the top of the workbench, the sponge body is placed on the top of the conveyor belt, the top outer wall of the workbench is provided with symmetrically distributed conveyor belts, the sponge body is placed between two conveyor belts, the air supply pipe is provided with first ventilation holes on the left and right sides, the left and right outer walls of the air supply pipe are provided with side air ducts, one end of the side air duct is connected to the first ventilation hole, the left and right inner walls of the air supply pipe are provided with symmetrically distributed air inlet pipes, one end of the air inlet pipe is connected to the first ventilation hole.

[0011] By adopting the above scheme, since the outer wall of one side of the sponge body is close to the outer wall of the conveyor belt, the hot air blown into the air supply pipe is introduced into the air inlet pipe and blown out through the side air duct. The hot air flows between the conveyor belt and the drying oven, thereby increasing the temperature of the conveyor belt and preventing the temperature of the conveyor belt from being too low, causing uneven heating of the sponge body and affecting the quality of the sponge body molding.

[0022] The utility model discloses a drying oven structure for producing biological sponges, which is mainly applied to the existing drying oven to increase the temperature in the drying oven by installing a heating block inside the drying oven. The heating block is used to heat the sponge in the drying oven unevenly, resulting in uneven density of the sponge, thereby reducing the quality of the sponge.

[0023] Reference Figure 1 and Figure 2 , a drying oven structure for biological sponge production, including a workbench 6, a drying oven box 11 and a sponge body 8, and also includes:

[0024] A conveying mechanism, used for conveying the sponge body 8;

[0025] The heating mechanism includes a heater 5 arranged on the top of a drying oven 11, an input end of the heater 5 is connected to a circulation pipe 3, an end of the drying oven 11 away from the heater 5 is provided with a return air pipe 9, one end of the circulation pipe 3 is fixedly connected to the return air pipe 9, an output end of the heater 5 is provided with an air supply pipe 12, one end of the air supply pipe 12 is provided in the drying oven 11.

[0026] Specifically, when the sponge body 8 passes through the drying oven 11, the heater 5 is started, and hot air is blown into the drying oven 11 through the air supply pipe 12. The air is heated and then blown into the drying oven 11. The hot air flows in the drying oven 11 and contacts the sponge body 8. The heat is transferred to the sponge body 8 through heat conduction and convection heat transfer, so that the sponge body 8 is foamed and dried at a suitable temperature. The sponge body 8 is gradually solidified and discharged from the drying oven 11. The hot air in the drying oven 11 flows back into the circulation pipe 3 from the return air pipe 9 at one end of the drying oven 11, and then enters the drying oven 11 through the air supply pipe 12. The hot air circulation method is adopted to reduce heat loss, ensure that the surface of the sponge body 8 is evenly heated, and improve the drying efficiency.

[0027] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the transport mechanism includes a conveyor belt 7 arranged on the top of the workbench 6, the sponge body 8 is placed on the top of the conveyor belt 7, the top outer wall of the workbench 6 is provided with symmetrically distributed conveyor belts 1, the sponge body 8 is placed between the two conveyor belts 1, the left and right sides of the air supply pipe 12 are provided with first ventilation holes, the left and right outer walls of the air supply pipe 12 are provided with side air ducts 14, one end of the side air duct 14 is connected to the first ventilation hole, the left and right inner walls of the air supply pipe 12 are provided with symmetrically distributed air inlet pipes 15, one end of the air inlet pipe 15 is connected to the first ventilation hole.

[0028] Specifically, since the outer wall of one side of the sponge body 8 is attached to the outer wall of the conveyor belt 1, the hot air blown into the air supply pipe 12 is introduced into the air inlet pipe 15 and then blown out through the side air duct 14. The hot air flows between the conveyor belt 1 and the drying oven 11, thereby increasing the temperature of the conveyor belt 1 and preventing the temperature of the conveyor belt 1 from being too low, causing uneven heating of the sponge body 8 and affecting the molding quality of the sponge body 8.

[0029] Reference Figure 2 In a preferred embodiment, a soft wind plate 13 is provided at one end of the air supply pipe 12, a symmetrically distributed wind shield 10 is provided at one end of the drying oven 11, and an insulation sleeve 2 is provided on the outer wall of the drying oven 11.

[0030] Specifically, the thermal insulation sleeve 2 reduces heat loss and improves the thermal insulation performance of the drying oven 11. The two wind shields 10 block one end of the drying oven 11 to reduce the leakage of hot air, thereby reducing heat loss. The hot air is blown out from the air supply pipe 12. After passing through the soft wind plate 13 at a faster speed, it is blown out from the micropores on the surface of the soft wind plate 13, making the wind force softer and preventing the wind force from being too strong and causing the sponge body 8 to deform.

[0031] Reference Figure 1 and Figure 4In a preferred embodiment, an air supply box 4 is provided on the top outer wall of the circulation pipe 3, a dustproof net 17 is provided on one side of the air supply box 4, and an air supply hole 16 is opened on the top of the circulation pipe 3, and one end of the air supply hole 16 is connected to the inside of the air supply box 4.

[0032] Specifically, the hot air circulates in the circulation pipe 3 and the drying oven 11, and part of the hot air leaks out. Fresh air is introduced from the outside through the air replenishment box 4, and at the same time cooperates with the heater 5 to realize the circulation of the hot air.

[0033] Working principle: When in use, when the sponge body 8 passes through the drying oven 11, the heater 5 is started, and hot air is blown into the drying oven 11 through the air supply pipe 12. The air is heated and then blown into the drying oven 11. The hot air flows in the drying oven 11 and contacts the sponge body 8. The heat is transferred to the sponge body 8 through heat conduction and convection heat transfer, so that the sponge body 8 is foamed and dried at a suitable temperature. The sponge body 8 is gradually solidified and discharged from the drying oven 11. The hot air in the drying oven 11 flows back into the circulation pipe 3 from the return air pipe 9 at one end of the drying oven 11, and then enters the drying oven 11 through the air supply pipe 12. After the hot air part of the air supply pipe 12 is introduced into the air inlet pipe 15, it is blown out through the side air duct 14. The hot air flows between the conveyor belt 1 and the drying oven 11 to increase the temperature of the conveyor belt 1.
