Specific implementation

[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Reference Figure 1 , Figure 2 An embodiment provided by the utility model:

[0027] A vacuum drying equipment with heat equalizing heating function, including cabinet door mechanism 1, the one side of cabinet door mechanism 1 is hingedly arranged with cabinet body mechanism 2, the inside one side upper end of cabinet body mechanism 2 is fixedly arranged with control panel 3, the rear end one side of cabinet body mechanism 2 is slidably arranged with filter plate 4, the inner wall of cabinet body mechanism 2 is fixedly arranged with several heating pipes 5, the inner wall of cabinet body mechanism 2 is provided with heat conduction plate mechanism 6, the upper end of heat conduction plate mechanism 6 is fixedly connected with support 7, the inside one side lower end of cabinet body mechanism 2 is fixedly arranged with vacuum pump 8.

[0028] Specifically, the cabinet door mechanism 1 and the cabinet mechanism 2 form the shell of the equipment, the control panel 3 adopts a PLC intelligent control system, and integrates equipment operation and control functions. The operator can set the drying temperature, vacuum degree, drying time and other parameters through the control panel 3, and the display screen provided thereby can display the equipment operating parameters in real time, facilitating the operator to monitor the equipment operation. The filter plate 4 is designed in a replaceable manner and is fixed by a rotatable fixed sheet. During the operation of the equipment, the filter plate 4 can intercept dust, impurities and other particles in the air to prevent them from entering the inside of the cabinet mechanism 2, and when the filter plate 4 is clogged, the operator can directly pull it out from the rear end of the cabinet to clean or replace it. The heat conduction plate mechanism 6 divides the internal space of the cabinet mechanism 2 into five parts, and the heating pipes 5 are uniformly arranged. The heating pipes 5 are made of materials with high heat conduction efficiency, and the heat generated thereby can be quickly transferred to the internal space of the cabinet mechanism 2 during operation. Moreover, by reasonably arranging the heating pipes 5 and cooperating with the heat conduction plate mechanism 6, the heat can be evenly distributed to all places, ensuring that the materials are evenly heated and meeting the drying temperature requirements of different materials. The bracket 7 is used to fix and place the material disc to be dried by clamping, so that the material can be fully contacted with hot air during the drying process, thereby improving the drying efficiency. The vacuum pump 8 is an oil-free diaphragm vacuum pump 8, which does not produce oil stains during operation, thereby ensuring the cleanliness of the medical supplies and other materials. The vacuum pump 8 is connected to the inside of the cabinet mechanism 2 through a pipeline, and can quickly extract the air in the cabinet mechanism 2 to form a vacuum environment, thereby reducing the boiling point of the materials and accelerating the evaporation of moisture.

[0029] Reference Figure 3 The cabinet door mechanism 1 comprises a handle 101, and the handle 101 is fixedly arranged on one side of a cabinet door body 102. The cabinet door body 102 is fixedly connected with a sealing ring 103 on one side.

[0030] Specifically, the handle 101 is installed on one side of the cabinet door body 102, which facilitates the operator to open and close the cabinet door. The sealing ring 103 fixed on the edge of the cabinet door body 102 is tightly attached to the cabinet mechanism 2 when the cabinet door is closed, thereby forming a sealing structure to prevent external air from entering the inside of the cabinet mechanism 2, maintain the stability of the vacuum drying environment, and avoid the influence of external moisture, dust and other impurities on the drying effect.

[0031] Reference Figure 4 The cabinet mechanism 2 comprises a cabinet shell 201, and the cabinet shell 201 is fixedly provided with a heat insulation layer 202 on the inner wall. The heat insulation layer 202 is fixedly provided with a protective layer 203 on the inner wall.

[0032] Specifically, the cabinet shell 201 serves as the main body frame of the device and provides structural support; the heat insulation layer 202 of the inner wall is made of high-efficiency heat insulation material such as aluminum silicate fiber cotton, which effectively reduces heat dissipation to the outside during operation of the device, reduces energy consumption, and avoids accidental touching of the high-temperature shell by the operator to cause burns; the protective layer 203 on the inner side of the heat insulation layer 202 is mainly made of corrosion-resistant and wear-resistant stainless steel material, which prevents the generated steam and chemical substances during the drying process from corroding the cabinet body, prolongs the service life of the device, and the smooth surface is easy to clean.

[0033] Reference Figure 5 The heat conduction plate mechanism 6 includes a heat conduction plate 603, the outer surface of the heat conduction plate 603 is provided with a through hole 604, and the upper and lower ends of the heat conduction plate 603 are fixedly provided with sliding blocks 601. The heat conduction plate 603 is slidably connected with slide rails 602 at both ends.

[0034] Specifically, the through hole 604 formed on the surface of the heat conduction plate 603 is a key structure for forming hot air circulation. Hot air can quickly shuttle in the cabinet mechanism 2 through the through hole 604, enhancing the flowability of hot air, avoiding local heat accumulation or deficiency, and strengthening the heating effect; the sliding blocks 601 at the upper and lower ends of the heat conduction plate 603 are slidably connected with the slide rails 602 on the inner wall of the cabinet mechanism 2, so that the heat conduction plate 603 can move along the slide rails 602, facilitating extraction and replacement.

[0035] Working principle: when in use, the operator opens the cabinet door mechanism 1 through the handle 101, pulls open the heat conduction plate mechanism 6, places the material to be dried on the tray, the tray is fixed on the support 7, closes the cabinet door body 102, and the sealing ring 103 ensures the sealing property of the cabinet mechanism 2. After setting the drying parameters on the control panel 3, the device is started, the vacuum pump 8 extracts the air in the cabinet mechanism 2 to form a vacuum environment, the heating pipe 5 is powered to generate heat, the heat is circulated and flows through the through hole 604 on the heat conduction plate mechanism 6, so that the hot air is uniformly distributed and fully contacts with the material. The filter plate 4 intercepts impurities, the control panel 3 monitors and adjusts the operating parameters of the device in real time, and the device automatically stops after reaching the set drying time, and the operator takes out the dried material.

[0036] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application.
