Description

Technical Field

[0001] This utility model relates to the field of drying technology, and in particular to an air source heat pump drying device. Background Technology

[0002] An air source heat pump drying device, also known as an air source heat pump dryer, is a device that uses the reverse Carnot cycle principle to absorb heat from the air and transfer it to the material to be dried, thereby achieving material drying.

[0003] To allow outside air to enter the air inlet, a fan is installed inside the air inlet pipe of the air source heat pump dryer. To prevent foreign objects from entering, a protective net is installed at the end of the air inlet. After a period of use, impurities gradually accumulate on the protective net, causing the mesh to shrink or even become blocked. As a result, the protective net needs to be removed for cleaning and replacement. Since the protective net is bolted to the machine body, the disassembly and assembly process requires the use of auxiliary tools to repeatedly rotate each set of bolts, making the entire process cumbersome and time-consuming. Therefore, we propose an air source heat pump drying device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an air source heat pump drying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air source heat pump drying device includes an air source heat pump dryer. An air inlet pipe is connected to the side of the air source heat pump dryer, and a protective net covers the opening of the air inlet pipe. Four sets of mounting brackets are symmetrically welded to the side of the protective net. A fixed ring is connected to the outer side of the air inlet pipe, and a movable ring is provided on the side of the fixed ring. A movable rod is inserted inside the movable ring, and a fixed rod is inserted inside the movable rod. One end of the fixed rod is connected to the inner wall of the movable rod via a connecting spring, and the other end of the fixed rod is connected to the fixed ring. Four sets of insertion slots are opened inside the movable ring.

[0007] Preferably, the inner side of the movable ring is connected to four sets of limiting posts, and the outer dimensions of the four sets of limiting posts are smaller than those of the mounting frame.

[0008] Preferably, a buffer pad is glued to the inner side of the movable ring, and a slot is formed inside the buffer pad at a position corresponding to the insertion slot.

[0009] Preferably, the fixed ring is connected to a limit strip on the side near the moving ring, and four sets of limit strips are provided.

[0010] Preferably, the inner side of the movable rod is symmetrically connected with guide bars, and the outer wall of the fixed rod is provided with a slide rail adapted to the guide bars.

[0011] Preferably, the inner dimension of the insertion slot is larger than the outer dimension of the mounting bracket, and the inner wall of the insertion slot is glued with a rubber pad.

[0012] Preferably, a rubber post is glued to the end of the limiting post, and the other end of the rubber post abuts against the fixing ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device is equipped with a fixed ring and a movable ring. During use, the operator only needs to pull the movable ring to separate it from the fixed ring. At this time, the operator only needs to rotate the protective net to remove the four sets of mounting brackets from the insertion slot. The entire disassembly and assembly process does not require the use of auxiliary tools, which can effectively improve the convenience of the operator when inspecting the protective net.

[0015] 2. By setting limit strips and limit posts, the device allows the limit posts connected to the inner side of the moving ring to be engaged into the corresponding mounting frame during the installation of the protective net, thus ensuring the limiting effect on the mounting frame. With the setting of four sets of limit strips, it is easy to limit the mounting frame when it is rotated to the appropriate position, so that the limit posts can be accurately inserted into the mounting frame later.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 An air source heat pump drying device includes an air source heat pump dryer 1. An air inlet pipe 2 is connected to the side of the air source heat pump dryer 1, and a protective net 3 covers the opening of the air inlet pipe 2. The drying principle of the air source heat pump dryer 1 is existing technology and will not be described in detail here. Four sets of mounting brackets 4 are symmetrically welded to the side of the protective net 3. A fixing ring 5 is connected to the outer side of the air inlet pipe 2, and a movable ring 6 is provided on the side of the fixing ring 5. A movable rod 7 is inserted inside the movable ring 6, and a fixed rod 8 is inserted inside the movable rod 7. One end of the fixed rod 8 is connected to the inner wall of the movable rod 7 via a connecting spring 9, and the other end of the fixed rod 8 is connected to... The fixed ring 5 is connected to the movable ring 6, which has four sets of insertion slots 10 inside. Through the cooperation of the movable rod 7, the fixed rod 8 and the connecting spring 9, the lateral movement of the movable ring 6 can be met, so that the workers can easily move the movable ring 6 away from the fixed ring 5. When the workers pass the mounting bracket 4 through the insertion slot 10 and it abuts against the fixed ring 5, the mounting bracket 4 can be rotated, so that the position of the mounting bracket 4 and the position of the insertion slot 10 are misaligned. At this time, the workers can stop pulling the movable ring 6, so that the movable ring 6 abuts against the outside of the mounting bracket 4 through the elastic force of the connecting spring 9, so as to realize the quick installation of the mounting bracket 4.

[0024] Furthermore, refer to Figure 3 and Figure 5 It can be seen that the inner side of the moving ring 6 is connected to four sets of limiting posts 13, and the outer dimensions of the four sets of limiting posts 13 are smaller than those of the mounting frame 4. Through the four sets of smaller limiting posts 13, the moving ring 6 can be inserted into the interior of the mounting frame 4 when it is reset, so as to limit the installation angle of the mounting frame 4 and prevent the mounting frame 4 from easily rotating during the installation process, thus effectively ensuring the stability of the mounting frame 4 during the installation process.

[0025] Furthermore, refer to Figure 5It can be seen that the inner side of the moving ring 6 is glued with a buffer pad 12, and the inside of the buffer pad 12 is provided with a slot corresponding to the insertion slot 10. The rubber plate glued to the inner side of the moving ring 6 can further improve the tightness of the mounting bracket 4 being inserted between the fixed ring 5 and the moving ring 6. With the slot provided inside the rubber plate, the normal insertion requirements of the mounting bracket 4 can be met.

[0026] Furthermore, refer to Figure 4 It can be seen that the fixed ring 5 is connected to the side of the moving ring 6 with a limit strip 11, and there are four sets of limit strips 11. When the operator passes the mounting bracket 4 through the insertion slot 10 and abuts against the fixed ring 5, the mounting bracket 4 can be rotated to make it misalign with the insertion slot 10. The rotation angle of the mounting bracket 4 can be limited by the obstruction of the four sets of limit strips 11, so that the position of the mounting bracket 4 can quickly correspond to the position of the limit post 13. This allows the moving ring 6 to automatically drive the limit post 13 into the mounting bracket 4 when it is reset.

[0027] Furthermore, refer to Figure 5 It can be seen that the inner side of the movable rod 7 is symmetrically connected with guide strips 14, and the outer wall of the fixed rod 8 is provided with a slide rail that matches the guide strips 14. Through the cooperation of the guide strips 14 and the slide rail, the reliability of the movable rod 7 when sliding along the outer wall of the fixed rod 8 can be effectively guaranteed.

[0028] Furthermore, refer to Figure 4 It can be seen that the inner dimension of the insertion slot 10 is larger than the outer dimension of the mounting bracket 4. The inner wall of the insertion slot 10 is glued with a rubber pad. Since the size of the insertion slot 10 is large, it can meet the requirement of smooth insertion of the mounting bracket 4. With the rubber pad, the inner wall of the insertion slot 10 can be protected.

[0029] Furthermore, refer to Figure 5 It can be seen that the end of the limiting post 13 is glued with a rubber post, and the other end of the rubber post abuts against the fixing ring 5. When the moving ring 6 is reset by the elastic force of the connecting spring 9, the rubber post at the end of the limiting post 13 can effectively prevent the end of the limiting post 13 from directly colliding with the fixing ring 5, thereby achieving protection of the end of the limiting post 13.

[0030] Working Principle: When using this utility model, the operator can first install the device in a suitable location, and then start the air source heat pump dryer 1. At this time, the fan inside the air inlet pipe 2 can transport outside air into the air source heat pump dryer 1 for drying. After a period of use, a lot of debris will accumulate on the protective net 3 covering the end of the air inlet pipe 2. At this time, the operator can manually pull the moving ring 6 to separate it from the fixed ring 5. At this time, the four sets of limiting posts 13 connected to the inner side of the moving ring 6 can be pulled out from the inside of the four sets of mounting brackets 4 to release the limitation on the mounting brackets 4. Then the operator can drive the protective net 3 and the mounting brackets 4 to rotate so that the positions of the four sets of mounting brackets 4 and the four sets of insertion slots 10 are aligned. Corresponding to the position, the staff can remove the mounting bracket 4 from the inside of the moving ring 6, and then clean the debris on the protective net 3. When the protective net 3 reaches the end of its service life, it can be replaced. When the protective net 3 needs to be installed, the staff can pull the moving ring 6 again and insert each set of mounting brackets 4 into the insertion slot 10 and into contact with the fixed ring 5. Then, by rotating the mounting bracket 4, when the mounting bracket 4 cannot be rotated due to the obstruction of the limit strip 11, the staff can stop pulling the moving ring 6. At this time, the limit post 13 connected to the inside of the moving ring 6 can be inserted into the corresponding mounting bracket 4 to achieve the rapid installation of the protective net 3. The above is the complete working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
