[0001] The utility model relates to the technical field of drying, in particular to a pipeline type hot air circulation system. Background technology:

[0002] The Chinese utility model patent with authorization announcement number CN 202959060 U discloses a shoe production line drying system using an air source heat pump, including a drying box, a conveyor belt passing through the drying box and used to convey shoes, and a drive motor for driving the conveyor belt. It also includes an air source heat pump device, a hot air circulation system and a heating lamp device. The air source heat pump device includes a refrigerant pipeline, a compressor, a condenser, a throttling device, an evaporator and a gas-liquid separator; the hot air circulation system includes a downwind duct, an upwind duct and a side duct; the heating lamp device includes a heating lamp mounting frame arranged directly above the conveyor belt and a plurality of heating lamps arranged in the heating lamp mounting frame, and the plurality of heating lamps are arranged in parallel.

[0003] The hot air circulation system used in the shoe production line drying system using the air source heat pump needs to cooperate with the circulating fan to circulate the hot air generated by the air source heat pump device. The patent specification

[0029] paragraph records: When the drying system is working, the air source heat pump device absorbs the low-temperature heat at the end of the evaporator 2, and finally makes the condenser 7 installed in the air duct release heat through the action of the refrigerant. After the circulating fan 8 is started, the hot air is first blown from the side air duct 9-3 to the upper air duct 9-2, and the hot air in the upper air duct 9-2 is blown to the conveyor belt 13 through the opening. After the hot air passes through the conveyor belt 13, it is sucked into the lower air duct 9-1 by the circulating fan 8 through the opening of the lower air duct 9-1. Finally, the wind is heated by the condenser 7, and the shoes conveyed on the conveyor belt 13 can be dried by such circulation. The condenser 7 and the circulating fan 8 can be installed in any of the upper air duct 9-2, the lower air duct 9-1, and the side air duct 9-3 as needed, and can play the role of circulating the hot air in the wind-driven drying box 14.

[0004] That is to say, the hot air circulation system used in the above-mentioned shoe production line drying system using air source heat pump includes a downwind duct, an upwind duct and a side duct, that is, the downwind duct, the upwind duct and the side duct need to cooperate with each other to realize air circulation, the upwind duct cannot circulate alone to produce a hot air circulation effect, and the downwind duct cannot circulate alone to produce a hot air circulation effect. If the use requirement only requires the hot air circulation effect of the upwind duct or the downwind duct, the hot air circulation system used in the above-mentioned shoe production line drying system using air source heat pump is not applicable, and has a complex structure and high cost.

[0005] In view of this, the inventor proposes the following technical solution. Utility model content:

[0006] The utility model aims to overcome the deficiencies of the prior art and provide a pipeline type hot air circulation system.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions: the duct-type hot air circulation system comprises: a casing having a channel for the products to be dried, the casing being provided with a plurality of through holes connected to the channel; a heating module being installed in the channel and used for heating the air in the channel to dry the products to be dried or directly drying the products to be dried; a hot air circulation structure comprising a main duct and a plurality of branch ducts arranged on the outside of the main duct and connected to the main duct, and a blower installed on the main duct, the blower being also fixedly connected to the casing, and the air inlet of the blower being connected to the through hole to be connected to the channel, thereby inhaling the hot air heated by the heating module in the channel, the air outlet of the blower being connected to the main duct, the branch duct being fixed in the channel and being located beside the heating module, and the branch duct having a plurality of hot air holes for discharging hot air to dry the products to be dried.

[0008] Furthermore, in the above technical solution, the casing includes a semi-square frame-shaped outer shell and a front cover installed at the front end of the outer shell, an installation space is formed between the front cover and the outer shell, the outer shell has the through hole, and the outer shell is provided with an opening that passes through the installation space and the channel, the blower and the main pipe are fixed in the installation space, and the branch pipe passes through the opening to extend into the channel.

[0009] Furthermore, in the above technical solution, a port is formed at one end of the branch pipe and is connected to the main pipe, and one end of the branch pipe is a closed structure.

[0010] Furthermore, in the above technical solution, the main pipe and the branch pipes are both square pipes.

[0011] Furthermore, in the above technical solution, a plurality of heat dissipation holes for connecting the installation space with the outside are arranged on the outer side of the front cover.

[0012] Furthermore, in the above technical solution, the heating module includes a plurality of shells spaced apart and distributed in the channel and a heating lamp fixed to the shells.

[0013] Furthermore, in the above technical solution, the longitudinal section of the shell is trapezoidal and has a bell mouth.

The heating module dries the products to be dried by heating the air in the channel, or the heating module directly dries the products to be dried. No matter which method is used, the air in the channel will be heated into hot air. At the same time, the air inlet of the blower is connected to the channel, and then the hot air heated by the heating module in the channel is sucked into the blower when the blower is working. The hot air is converted into hot air and enters the main pipeline, and then enters multiple branch pipelines, and finally the hot air is discharged from the hot air holes of the branch pipelines to dry the products to be dried. The hot air will be sucked into the blower later, so as to achieve hot air circulation and blown to the channel of the casing, and then dry the products to be dried, so that the products to be dried are heated more evenly and the drying effect is better. At the same time, the energy consumption of the heating module can be reduced, which is more energy-saving and has higher power-saving and environmental protection effects. In addition, the hot air circulation structure in the utility model has a simpler structure and can circulate alone to produce a hot air circulation effect in one direction, that is, the utility model can not only be installed alone above the conveyor belt that transports the products to be dried to realize the upper hot air circulation system, but can also be installed alone below the conveyor belt that transports the products to be dried to realize the upper hot air circulation system.

[0021] The utility model is further described below in conjunction with specific embodiments and drawings.

[0022] See Figure 1-5 As shown, a duct-type hot air circulation system comprises: a casing 1, a heating module 2 and a hot air circulation structure 3.

[0023] The housing 1 has a passage 101 for the products to be dried to pass through, and the housing 1 is provided with a plurality of through holes 102 connected to the passage 101. The heating module 2 is installed in the passage 101, and is used to heat the air in the passage 101 to dry the products to be dried or directly dry the products to be dried. The hot air circulation structure 3 includes a main pipeline 31, a plurality of branch pipelines 32 arranged outside the main pipeline 31 and connected to the main pipeline 31, and a blower 33 installed on the main pipeline 31, the blower 33 is also fixedly connected to the housing 1, and the air inlet 331 of the blower 33 is connected to the through hole 102 to communicate with the passage 101, and then the hot air heated by the heating module 2 in the passage 101 is sucked in, the air outlet 332 of the blower 33 is connected to the main pipeline 31, the branch pipeline 32 is fixed in the passage 101, and is located beside the heating module 2, and the branch pipeline 32 has a plurality of hot air holes 321 for discharging hot air to dry the products to be dried. When the utility model is in use, the housing 1 can be installed above a conveyor belt for conveying products to be dried (e.g., shoes to be shaped), and the heating module 2 and the hot air circulation structure 3 work simultaneously. The heating module 2 heats the air in the channel 101 to dry the products to be dried, or the heating module 2 directly dries the products to be dried. In either case, the air in the channel 101 will be heated to become hot air. At the same time, the air inlet 331 of the blower 33 is connected to the channel 101, and then the air in the channel 101 is sucked in when the blower 33 is working. The hot air heated by the heating module 2 in 1 is transformed into hot air and enters the main pipe 31, and then enters the multiple branch pipes 32, and finally the hot air is discharged from the hot air holes 321 of the branch pipes 32 to dry the products to be dried. The hot air will be sucked into the blower 33, so that the hot air is circulated and blown to the channel 101 of the casing 1, and then the products to be dried are dried, so that the products to be dried (such as shoes to be shaped) are heated more evenly and the drying effect is better. At the same time, the energy consumption of the heating module 2 can be reduced, which is more energy-saving and has higher power-saving and environmental protection effects. In addition, the hot air circulation structure 3 in the present invention has a simpler structure and can circulate alone to produce a hot air circulation effect in one direction, that is, the present invention can not only be installed alone above the conveyor belt that transports the products to be dried (such as shoes to be formed) to realize the upper hot air circulation system, but can also be installed alone below the conveyor belt that transports the products to be dried (such as shoes to be formed) to realize the upper hot air circulation system. Two duct-type hot air circulation systems can also be installed respectively above and below the conveyor belt that transports the products to be dried (such as shoes to be formed) and used simultaneously, and the two duct-type hot air circulation systems work independently without affecting each other, the structure is simpler, and it is easy to repair and maintain.

[0024] There are two duct-type hot air circulation systems, which are symmetrically arranged up and down, so as to be installed respectively on the upper and lower sides of the conveyor belt for conveying the products to be dried (such as shoes to be shaped) and used simultaneously. The two duct-type hot air circulation systems work independently without affecting each other, and the structure is simpler and easy to repair and maintain.

[0025] The casing 1 includes a semi-square-frame-shaped outer shell 11 and a front cover 12 installed at the front end of the outer shell 11, an installation space 10 is formed between the front cover 12 and the outer shell 11, the outer shell 11 has the through hole 102, and the outer shell 11 is provided with an opening 111 passing through the installation space 10 and the channel 101. The blower 33 and the main pipe 31 are fixed in the installation space 10, and the branch pipe 32 passes through the opening 111 to extend into the channel 101. It has a simple structure and is easy to install.

[0026] One end of the branch pipe 32 is formed with a port and is connected to the main pipe 31. One end of the branch pipe 32 is a closed structure, so that after the hot air enters the branch pipe 32, it can only be discharged from the hot air hole 321, which will form a certain pressure, so that the hot air ejected from the hot air hole 321 has a better effect.

[0027] The main pipe 31 and the branch pipe 32 are both square pipes, so that the main pipe 31 and the housing 11 are in plane contact, with a large contact area and more stable installation. The branch pipe 32 and the channel 101 are in plane contact, with a large contact area and more stable installation.

[0028] The outside of the front cover 12 is provided with a plurality of heat dissipation holes 121 for connecting the installation space 10 with the outside, which facilitates the air flow between the installation space 10 and the outside, so that the blower placed in the installation space 10 can dissipate heat better, thereby ensuring the working quality and service life of the blower.

[0029] The heating module 2 includes a plurality of shells 21 spaced apart in the channel 101 and a heating lamp 22 fixed to the shell 21. The structure is very simple. When the heating lamp 22 is working, it emits infrared light to heat the air in the channel 101 and dry the products to be dried. The shell 21 can protect the heating lamp 22 to a certain extent and improve its service life. The longitudinal section of the shell 21 is trapezoidal and has a trumpet mouth 211, which has the function of focusing and guiding light. The heating lamp 22 emits infrared light to heat the air in the channel 101 and dry the products to be dried, which has a better effect.

[0030] In summary, when the utility model is in use, the housing 1 can be installed above the conveyor belt that conveys the products to be dried (such as shoes to be shaped), and the heating module 2 and the hot air circulation structure 3 work simultaneously. The heating module 2 dries the products to be dried by heating the air in the channel 101, or the heating module 2 directly dries the products to be dried. In either case, the air in the channel 101 will be heated into hot air. At the same time, the air inlet 331 of the blower 33 is connected to the channel 101, and then the air in the channel is sucked in when the blower 33 is working. The hot air heated by the heating module 2 in 101 becomes hot air and enters the main pipe 31, and then enters multiple branch pipes 32, and finally the hot air is discharged from the hot air holes 321 of the branch pipes 32 to dry the products to be dried. The hot air will then be sucked into the blower 33, so that the hot air is circulated and blown to the channel 101 of the casing 1, and then the products to be dried are dried, so that the products to be dried (such as shoes to be shaped) are heated more evenly and the drying effect is better. At the same time, the energy consumption of the heating module 2 can be reduced, which is more energy-saving and has higher power-saving and environmental protection effects. In addition, the hot air circulation structure 3 in the present invention has a simpler structure and can circulate alone to produce a hot air circulation effect in one direction, that is, the present invention can not only be installed alone above the conveyor belt that transports the products to be dried (such as shoes to be formed) to realize the upper hot air circulation system, but can also be installed alone below the conveyor belt that transports the products to be dried (such as shoes to be formed) to realize the upper hot air circulation system. Two duct-type hot air circulation systems can also be installed respectively above and below the conveyor belt that transports the products to be dried (such as shoes to be formed) and used simultaneously, and the two duct-type hot air circulation systems work independently without affecting each other, the structure is simpler, and it is easy to repair and maintain.

Any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
