Description
Technical Field
[0001] This utility model belongs to the field of experimental equipment technology, specifically relating to a dryer opening device. Background Technology
[0002] In schools and research facilities, a dry environment is often required to store or dry certain samples. Although newer devices such as electronic drying ovens exist, and other desiccators with different structures are designed (as per patents CN201620834129.7 and CN202021147177.1), traditional glass desiccators remain widely used in laboratories and other research settings due to their advantages such as simple structure, low cost, maintenance-free operation, corrosion resistance, reliable function, and virtually zero power consumption (common desiccants can be recycled and reused). These glass desiccators are generally circular, with a diameter between 100 and 450 mm, and consist of three parts: a main body, a lid, and a partition. The desiccant is placed at the bottom of the main body, and the sample is placed on the partition above the desiccant. The top is sealed with the lid. The sealing surface between the main body and the lid is a flat, frosted surface, typically 10 to 25 mm wide. During use, petroleum jelly or vacuum grease is applied to the sealing surface to achieve a complete seal. Figure 1 When opening the desiccator lid, the main body needs to be held in place, and the lid needs to be pushed to separate them. Due to the tight seal between the main body and the lid, as well as the adhesive effect of the additives, opening the lid is quite difficult. Additives such as petrolatum are mainly composed of long-chain alkanes, cycloalkanes, or polymers, and contain antioxidants, thickeners, and other substances. When samples are stored for a long time or at low ambient temperatures, the fluidity of the additives decreases, and they may even stick to the sealing surface, making it difficult to open the lid manually. Workers often try to open the lid by tapping, but this method is time-consuming, laborious, and often ineffective. Furthermore, glass desiccators are easily damaged by tapping, and may even result in the loss of the samples inside. Summary of the Invention

Detailed Implementation
[0024] 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 one embodiment of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1 to 5 A dryer opening device includes a frame 1, a controller 61, a motor 62, and a heating belt 8.
[0026] In this utility model, the frame 1 is formed by the intersection and connection of four support columns 11 to 14 and the first layer crossbeams 201 to 204 and the second layer crossbeams 211 to 214 to form a stable structure. The support columns 11 and 12 extend upward in an arc shape to form handles 21, and the support columns 13 and 14 form handles 22.
[0027] Each pair of corresponding first-layer crossbeams 201-204 and second-layer crossbeams 211-214 has a column 31-34 between its middle section. The upper part of the column 31-34 is provided with fixing clips 51-54 in sequence. The fixing clips 51-54 are located on the same horizontal plane, are arc-shaped, and have anti-slip buffer pads on their surfaces, which can firmly fix the dryer body without damaging the glass material.
[0028] The fixing clamp 51 is non-retractable. The rear of the fixing clamp 52 has a connector 521, a screw 522, and a handle 523 in sequence. The fixing clamps 52 to 54 have the same structure. When the screws 522, 532, and 542 are rotated to fix the dryer body, the connectors 521, 531, and 541 can keep the fixing clamps 52 to 54 moving horizontally without rotating with them.
[0029] The lifting platform 41 is located inside and below the support columns 11-14. The lifting platform 41 can be completely independent, or the knob 42 of the lifting platform 41 is located at the bottom of the column 31. The height of the lifting platform 41 can be adjusted by adjusting the knob 42, thereby further adjusting the height of the dryer.
[0030] The controller 61 and the motor 62 are integrated into one structure and are fixed above the crossbeam 204 and the column 34.
[0031] The controller 61 has a setting button 611 and a display screen 612 on the front, and a control cable port 613 and a power interface 614 on the rear. The setting button 611 can set the temperature of the heating belt 8, heating time, torque, speed, stroke, output time, etc. The display screen 612 can display the setting parameters of the controller 61 and the operating status information of the heating belt 8 and the motor 62.
[0032] The telescopic rod 621 at the front of the motor 62 is parallel to the fixing rod of the fixing clamp 51 and the screw 532 of the fixing clamp 53 and is in the same vertical plane. The front of the telescopic rod 621 has a protective pad 622, which has the functions of anti-slip and cushioning. During the opening process, the telescopic rod 621 contacts and pushes the side of the sealing surface 921 of the dryer cover through the protective pad 622, and the protective pad 622 protects the dryer cover 92 from damage.
[0033] Please see Figure 6 , Figure 7 The heating strip 8 is a long, flexible structure with heating and heat preservation functions, and its length is not less than the circumference of the sealing surface of a common dryer. The first heating surface 81 and the second heating surface 82 are connected by a connecting surface 83. The tail ends of the first heating surface 81 and the second heating surface 82 are connected to a control line 85 and a plug 86, and the plug 86 matches the control line port 613. The connecting surface 83 is made of elastic, heat-resistant, and heat-insulating material, and there is a hole 84 near the head of the connecting surface 83.
[0034] The back of the first heating surface 81 and the second heating surface 82 are respectively embedded with a first group of magnetic sheets 8701-8739 and a second group of magnetic sheets 8801-8839 symmetrically distributed. The number of magnetic sheets depends on the length and spacing of the heating band 8. When the first heating surface 81 and the second heating surface 82 are folded inward around the connecting surface 83, the first group of magnetic sheets 8701-8739 and the second group of magnetic sheets 8801-8839 automatically attract and fix each other.
[0035] When opening the dryer using the dryer opening device of this utility model, the specific steps include: (1) Wrap the connecting surface 83 of the heating band 8 around the side of the sealing surface of the dryer. At the same time, the first heating surface 81 and the second heating surface 82 are folded inward along the connecting surface 83 and cover the upper part of the sealing surface 921 of the dryer cover and the lower part of the main sealing surface 911 respectively. The connecting surface 83 wraps the side of the sealing surface. At this time, the first set of magnetic sheets 8701~8739 and the second set of magnetic sheets 8801~8839 attract and fix each other. When the length of the heating band 8 is greater than the circumference of the sealing surface of the dryer, the excess part allows the first heating surface 81 and the second heating surface 82 to be directly attracted and hung down next to the dryer.
[0036] (2) Place the dryer with the heating belt 8 wound around it on the lifting platform 41, with the hole 84 facing the telescopic rod 621. The outer wall of the dryer body 91 is tightly attached to the fixing clamp 51. Adjust the knob 42 so that the telescopic rod 621 and the edge of the dryer cover sealing surface 921 are at the same level and inserted into the hole 84. The protective pad 622 is tightly attached to the side of the cover sealing surface 921. At this time, the sealing surface 911 of the dryer body is just lower than the telescopic rod 621. Figure 8 Rotate handles 523, 533, and 543 to make the fixing clips 51 to 54 fit tightly against and fix the outer wall of the dryer body 91.
[0037] (3) Connect plug 86 to control line port 613, connect controller 61 to power supply, set heating temperature, heat preservation time, torque, speed, stroke, output time and other parameters, and start controller 61 to run the lid opening program.
[0038] Taking the default parameters as an example: heating temperature 50 degrees Celsius, holding time 5 minutes, torque 70 N·m, speed 20 mm / min, stroke 10 mm, and output time 30 seconds, after the controller 61 starts, the heating belt 8 first heats the first heating surface 81 and the second heating surface 82 to 50 degrees Celsius and maintains it for 5 minutes. Then, the motor 62 drives the telescopic rod 621 to push the dryer cover 92 horizontally with a torque of 70 N·m. If it can move forward within 30 seconds, it moves forward 10 mm at a speed of 20 mm / min and then stops. At this time, the connecting surface 83 is stretched due to the movement of the dryer cover 92, and its elasticity protects the normal function of the heating belt 8. If it fails to move forward within 30 seconds, it stops outputting thrust and gives a prompt on the display screen 612. At this time, one or more parameters of temperature, holding time, torque, or output time can be increased and then restarted. During the opening process described above, the sealing surface of the dryer is heated evenly from all directions, which restores the fluidity of additives such as petroleum jelly within the sealing surface. Furthermore, the mechanical thrust is much greater than that of human power, and the speed is stable and controllable, making it easy and safe to move the lid.
[0039] This utility model is not limited to the details of the above embodiments. All embodiments are exemplary and not restrictive. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended to encompass all variations falling within the meaning and scope of equivalents of the claims. No reference numerals in the claims should be construed as limiting the scope of the claims. All modifications, variations, substitutions, etc., within the principles and spirit of this utility model are within the protection scope of this utility model.
