[0002] With the increasing demand for material drying in industrial production and agricultural processing, heat pump drying equipment has been widely used due to its advantages such as energy saving, environmental protection, and good drying effect. The airflow structure of the heat pump drying equipment plays a crucial role in delivering the hot air generated by the heat pump to the drying chamber. The air generated by the heat pump, with a certain temperature and humidity and carrying heat, is guided in an orderly manner from the heat source to the drying chamber through the airflow channel, providing the necessary heat source for drying the materials.

[0003] The existing airflow duct structure of heat pump drying equipment needs to be connected to the air outlet of the heat pump during use. However, the existing connection structure is relatively complex and the operation steps are relatively cumbersome, which can easily lead to reduced connection efficiency and cause inconvenience in use. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the airflow channel structure of the existing heat pump drying equipment needs to be connected to the air outlet of the heat pump during use. However, the existing connection structure is relatively complex and the operation steps are relatively cumbersome, which can easily lead to reduced connection efficiency and inconvenience in use. Therefore, this utility model proposes an airflow channel structure for heat pump drying equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an airflow duct structure for a heat pump drying equipment, comprising an airflow duct assembly, an installation assembly at one end of the airflow duct assembly, a dustproof assembly inside the airflow duct assembly, and a heat insulation assembly on the outside of the airflow duct assembly. The airflow duct assembly includes an air inlet pipe, and the installation assembly includes a heat pump air supply pipe and a connecting ring. The connecting ring is located on the outside of the air inlet pipe, and multiple rotating seats are distributed on the side of the connecting ring. A fastening element is connected to the outside of the rotating seat, and the fastening element is engaged with the heat pump air supply pipe. A spring is connected to the outside of the fastening element.

[0006] Preferably, the dustproof component includes multiple mounting blocks distributed on the inner wall of the air inlet pipe, filter elements are mounted on the sides of the mounting blocks, and multiple rotating shafts are distributed at one end of the air inlet pipe.

[0007] Preferably, the insulation component includes insulation cotton, which is sleeved on the outside of the air inlet pipe, and an insulation shell is provided on the outside of the insulation cotton.

[0008] Preferably, limit plates are symmetrically installed on the outer side of the spring, and limit rings are installed between the limit plates.

[0009] Preferably, a limiting baffle is installed on the outer side of the rotating shaft, and the limiting baffle is connected to the filter element.

[0010] Preferably, a connector is installed at one end of the air inlet pipe, and multiple branch pipes are distributed on the side of the connector.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, when the air inlet pipe is installed, the squeezing force is used to make the buckle engage with the heat pump air supply pipe. The spring helps to provide support for the buckle, thus ensuring the stability of the buckle engagement with the heat pump air supply pipe. Then, the limiting ring is installed inside the limiting plate. The limiting ring helps to limit the buckle, thus ensuring the stability and reliability of the air inlet pipe installation. The operation is convenient and does not require the use of complex connection structures, which facilitates rapid docking and installation, shortens the installation time of the equipment, improves installation efficiency, and facilitates normal use.

[0013] 2. In this utility model, the filter element is installed at one end of the air inlet pipe, and the mounting blocks are distributed on the inner wall of the air inlet pipe. Rotating the rotating shaft causes the limiting baffle to limit the filter element. The filter element is conducive to filtering dust and impurities, preventing dust and impurities from entering the air inlet pipe, preventing uneven temperature distribution due to blockage inside the air inlet pipe, ensuring the smooth flow of the air inlet pipe, and thus ensuring that the drying operation can be carried out stably. Rotating the limiting baffle makes it easy to remove the filter element, which is convenient for maintenance and replacement. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: an airflow duct structure for a heat pump drying equipment, including an airflow duct component 1, an installation component 2 at one end of the airflow duct component 1, a dustproof component 3 inside the airflow duct component 1, and a heat insulation component 4 on the outside of the airflow duct component 1. The airflow duct component 1 includes an air inlet pipe 101, and the installation component 2 includes a heat pump air supply pipe 201 and a connecting ring 202. The connecting ring 202 is located on the outside of the air inlet pipe 101, and multiple rotating seats 203 are distributed on the side of the connecting ring 202. A fastening member 204 is connected to the outside of the rotating seat 203. The fastening member 204 is engaged with the heat pump air supply pipe 201. A spring 205 is connected to the outside of the fastening member 204. Limiting plates are symmetrically installed on the outside of the springs 205, and limiting rings 207 are installed between the limiting plates.

[0023] In this embodiment, by connecting one end of the air inlet pipe 101 to the heat pump air supply pipe 201, the connecting ring 202 is connected to the surface of the heat pump air supply pipe 201. A sealing ring is installed on the connecting ring 202 to provide a sealing effect. When the air inlet pipe 101 is installed, the squeezing force causes the fastener 204 to engage with the heat pump air supply pipe 201. The spring 205 provides support for the fastener 204, thus ensuring the stability of the engagement between the fastener 204 and the heat pump air supply pipe 201. Then, the limiting ring 207 is installed inside the limiting plate. The limiting ring 207 provides a limiting effect for the fastener 204, thus ensuring the stability and reliability of the air inlet pipe 101 installation. The operation is convenient and does not require a complex connection structure, which facilitates rapid docking and installation, shortens the installation time of the equipment, improves installation efficiency, and facilitates normal use.

[0024] Example 2: As Figures 1-5 As shown, the dustproof component 3 includes multiple mounting blocks 302, which are distributed on the inner wall of the air inlet pipe 101. Filter elements 301 are mounted on the sides of the mounting blocks 302. Multiple rotating shafts 303 are distributed at one end of the air inlet pipe 101. The heat insulation component 4 includes heat insulation cotton 401, which is sleeved on the outside of the air inlet pipe 101. A heat insulation shell 402 is provided on the outside of the heat insulation cotton 401. A limiting baffle 304 is installed on the outside of the rotating shafts 303. The limiting baffle 304 is connected to the filter element 301. A connector 102 is installed at one end of the air inlet pipe 101. Multiple branch pipes 103 are distributed on the side of the connector 102.

[0025] In this embodiment, a filter element 301 is installed at one end of the air inlet pipe 101, and mounting blocks 302 are distributed on the inner wall of the air inlet pipe 101. Rotating the rotating shaft 303 causes the limiting baffle 304 to limit the filter element 301. The filter element 301 is conducive to filtering dust and impurities, preventing dust and impurities from entering the air inlet pipe 101, preventing uneven temperature distribution due to blockage inside the air inlet pipe 101, ensuring the smooth flow of the air inlet pipe 101, and thus ensuring that the drying operation can be carried out stably. Rotating the limiting baffle 304 makes it easy to remove the filter element 301, which is convenient for maintenance and replacement. The insulation cotton 401 and the insulation shell 402 are used to provide insulation for the air inlet pipe 101, reduce the heat loss of hot air during the transportation process, enhance the drying effect, and thus improve the work efficiency. The branch pipe 103 is conducive to dispersing heat.

[0026] The working principle of this embodiment is as follows: In use, the filter element 301 is first installed at one end of the air inlet pipe 101, and the mounting blocks 302 are distributed on the inner wall of the air inlet pipe 101. Rotating the rotating shaft 303 causes the limiting baffle 304 to limit the filter element 301. The filter element 301 facilitates the filtration of dust and impurities, preventing dust and impurities from entering the air inlet pipe 101 and preventing uneven temperature distribution due to blockage inside the air inlet pipe 101, thus ensuring the unobstructed flow of the air inlet pipe 101. Then, one end of the air inlet pipe 101 is connected to the heat pump air supply pipe 201, thereby connecting the connecting ring 202 to the surface of the heat pump air supply pipe 201. A sealing ring is installed on the connecting ring 202 to facilitate sealing. The function of the system is as follows: When the air inlet pipe 101 is installed, the squeezing force causes the fastener 204 to engage with the heat pump air supply pipe 201. The spring 205 provides support for the fastener 204, thus ensuring the stability of the engagement between the fastener 204 and the heat pump air supply pipe 201. Then, the limiting ring 207 is installed inside the limiting plate, which provides a limiting function for the fastener 204, thus ensuring the stability and reliability of the air inlet pipe 101 installation. During use, the insulation cotton 401, together with the insulation shell 402, provides insulation for the air inlet pipe 101, reduces heat loss of hot air during transportation, enhances the drying effect, and thus improves work efficiency.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
