Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a new energy ultra-low temperature heat pump drying equipment. Background Technology

[0002] With the rapid development of new energy technologies, ultra-low temperature heat pump drying technology has emerged. Ultra-low temperature heat pump drying equipment is based on the reverse Carnot cycle principle. It uses a compressor to extract low-temperature heat energy from the surrounding environment, allowing it to operate normally even in ultra-low temperature conditions. Subsequently, the absorbed heat is released through a condenser and converted into high-temperature heat energy for drying. Its energy efficiency is higher than that of conventional air-source heat pump units in low-temperature environments. Existing new energy ultra-low temperature heat pump drying equipment can basically meet daily usage needs, but there are still some shortcomings that need improvement.

[0003] When the equipment operates in an ultra-low temperature environment, the air inlet window is prone to frost formation. This phenomenon severely hinders airflow, reduces the equipment's heat exchange efficiency, and consequently affects the drying effect. To solve this problem, some equipment uses manual defrosting, which not only consumes a lot of manpower but also requires regular maintenance by staff, increasing labor and time costs. Therefore, we propose a new energy ultra-low temperature heat pump drying equipment to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a new energy ultra-low temperature heat pump drying equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a new energy ultra-low temperature heat pump drying equipment, comprising a main body, an air inlet frame installed on the side of the main body, multiple sets of exhaust fans installed on the top of the main body, a first sleeve and a second sleeve respectively provided on both sides of the air inlet frame, a lead screw rotatably connected inside the first sleeve, a guide slide rod fixed inside the second sleeve, a servo motor provided at the top of the lead screw, the output end of the servo motor connected to the top of the lead screw, two sets of threaded sleeves threadedly connected to the outside of the lead screw, two sets of guide slide sleeves slidably connected to the outside of the guide slide rod, a rotating base installed at one end of each threaded sleeve and guide slide sleeve, a roller rotatably connected between the two sets of rotating bases, and multiple sets of heating strips installed at equal intervals on the outside of the roller.

[0006] As a further preferred embodiment of this technical solution, a detachable water collection drawer is installed at the bottom end of the air inlet side frame.

[0007] As a further preferred embodiment of this technical solution, the heating strip is a PTC ceramic heating element.

[0008] As a further preferred embodiment of this technical solution, the input end of the servo motor is electrically connected to the controller inside the main body of the device via a wire.

[0009] As a further preferred embodiment of this technical solution, the inner walls of the two sets of guide sleeves are fully fitted with the outer walls of the guide rods, and the two sets of guide sleeves are slidably connected to the guide rods.

[0010] As a further preferred embodiment of this technical solution, the outer wall of the heating strip on the roller is fully in contact with the surface of the air inlet side frame.

[0011] This utility model provides a new energy ultra-low temperature heat pump drying equipment, which has the following beneficial effects:

[0012] 1. This utility model features two sets of liftable rollers installed on the outside of the air inlet side frame, with multiple sets of heating strips installed on the outside of the rollers. When defrosting of the air inlet side frame surface is required, a servo motor is activated, driving the lead screw to rotate. This causes the threaded sleeve outside the lead screw to move along the lead screw axis, while the two sets of guide sleeves slide on the guide slide rods. This allows the two sets of rollers to rise and fall synchronously, and the rollers drive the heating strips to rise and fall along the air inlet side frame surface. The multiple heating strips on the roller surface heat the air inlet side frame surface themselves and, during the roller-driven rising and falling process, further heat the air inlet side frame surface, eliminating the need for manual defrosting and improving the drying efficiency of the device.

[0013] 2. This utility model has a detachable water collection drawer installed at the bottom of the air inlet side frame. When the frost layer at the air inlet side frame melts, the water droplets flow into the water collection drawer, thereby automatically collecting the defrosting water and preventing the defrosting water from clogging the bottom of the air inlet side frame.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0022] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0023] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a new energy ultra-low temperature heat pump drying equipment includes a main body 1, an air inlet frame 2 installed on the side of the main body 1, and multiple sets of exhaust fans 3 installed on the top of the main body 1. A first sleeve 4 and a second sleeve 5 are respectively arranged on both sides of the air inlet frame 2. A lead screw 7 is rotatably connected inside the first sleeve 4, and a guide slide rod 10 is fixed inside the second sleeve 5. A servo motor 6 is arranged at the top of the lead screw 7, and the output end of the servo motor 6 is connected to the top of the lead screw 7. Two sets of threaded sleeves 8 are threadedly connected to the outside of the lead screw 7, and two sets of guide slide sleeves 11 are slidably connected to the outside of the guide slide rod 10. A rotating base 9 is installed at one end of each of the threaded sleeves 8 and the guide slide sleeves 11. A roller 12 is rotatably connected between the two sets of rotating bases 9, and multiple sets of heating strips 13 are installed at equal intervals on the outside of the roller 12.

[0024] By installing two sets of liftable rollers 12 on the outside of the air inlet side frame 2, and multiple sets of heating strips 13 on the outside of the rollers 12, when defrosting of the surface of the air inlet side frame 2 is required, the servo motor 6 can be started to drive the lead screw 7 to rotate, causing the threaded sleeve 8 on the outside of the lead screw 7 to move along the axial direction of the lead screw 7. At the same time, the two sets of guide sleeves 11 slide on the guide slide rod 10, thereby allowing the two sets of rollers 12 to rise and fall synchronously. The two sets of rollers 12 drive the heating strips 13 to rise and fall along the surface of the air inlet side frame 2. The multiple sets of heating strips 13 on the surface of the rollers 12 heat themselves and, during the rising and falling process driven by the rollers 12, heat the surface of the air inlet side frame 2, eliminating the need for manual defrosting and improving the drying efficiency of the device.

[0025] In other embodiments, a removable water collection drawer 14 is installed at the bottom of the air inlet side frame 2;

[0026] With this design, when the frost layer at the air inlet side frame 2 melts, the water droplets flow into the water collection drawer 14, thereby automatically collecting the defrosting water and preventing the defrosting water from clogging the bottom of the air inlet side frame 2.

[0027] In other embodiments, the heating strip 13 is a PTC ceramic heating element;

[0028] Through this design, the PTC material achieves constant temperature and prevents overheating, improves the heating uniformity of the entire surface of the heating strip 13, and prevents the heating strip 13 from burning or exploding.

[0029] In other embodiments, the input terminal of the servo motor 6 is electrically connected to the controller inside the device body 1 via a wire;

[0030] This design allows the controller inside the main body 1 to control the start and stop of the servo motor 6 in real time, thereby enabling the servo motor 6 to start automatically during the defrosting process.

[0031] In other embodiments, the inner walls of the two sets of guide sleeves 11 are fully fitted with the outer wall of the guide rod 10, and the two sets of guide sleeves 11 and the guide rod 10 are slidably connected.

[0032] With this design, when the two sets of guide sleeves 11 move up and down along the surface of the guide slide rod 10, the guide sleeves 11 can be effectively prevented from shaking during the movement, thus improving the stability of the guide sleeves 11 during movement.

[0033] In other embodiments, the outer wall of the heating strip 13 on the roller 12 is fully in contact with the surface of the air inlet side frame 2;

[0034] With this design, when the roller 12 moves up and down along the surface of the air inlet side frame 2, multiple sets of heating strips 13 on the surface of the roller 12 can adhere to the surface of the air inlet side frame 2, and while heating the surface of the air inlet side frame 2, the roller 12 can rotate during the upward process.

[0035] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
