Description

Technical Field

[0001] The utility model relates to the technical field of vacuum drying equipment, in particular to a square static vacuum drying machine which is convenient for taking and placing materials. Background Art

[0002] Vacuum drying is to heat and dry the dried material under vacuum conditions. It uses a vacuum pump to extract air and moisture, so that the studio is in a vacuum state, which greatly speeds up the drying rate of the material and also saves energy. Square static vacuum dryers are widely used in the pharmaceutical, chemical, food, electronics and other industries. For example, in the pharmaceutical industry, it can be used to dry pharmaceutical raw materials, intermediates, etc.; in the food industry, it can be used to dry food raw materials such as meat, vegetables, and fruits; in the electronics industry, it can be used to dry electronic components, etc.

[0003] When some existing vacuum drying equipment is in use, the baking rack inside is difficult to control when it is taken out and is prone to tipping over, which poses certain risks in use.

[0004] For example, the announcement number CN216115013U discloses a square vacuum drying box that is easy to move out the baking rack. When the square vacuum drying box of this patent is in use, the baking rack is pushed into the box body, and then the limiting rod on one side of the triangular block is pressed, and then the triangular block moves downward and is stuck in the square groove to stabilize the baking rack. When the baking rack needs to be taken out, the limiting rod on one side of the pentagonal block is pressed, and the pentagonal block moves downward. Since the length of the pentagonal block is longer than that of the triangular block, the pentagonal block will push the insert plate and then push the baking rack to move during the downward movement, and then the triangular block is reset under the action of the reset spring, so that the baking rack can slide out under the action of gravity and the baking rack is taken out.

[0005] Although the patented square vacuum drying box was originally designed to avoid direct contact with the high-temperature baking rack, since the baking rack automatically slides out by gravity, its speed and stop position are difficult to accurately control. If there are slight deviations in the design or manufacture of the ramp plate, the baking rack may slide out too fast and hit the edge of the box or the ground, causing damage to the equipment or scattering of materials. If the baking rack loses balance or encounters an obstacle during the sliding process, it may suddenly topple over or pop out, posing a safety threat to people around it.

[0006] Therefore, it is necessary to invent a square static vacuum dryer that is convenient for taking and discharging materials to solve the above problems. Utility Model Content

[0038] In one aspect of this embodiment, multiple sets of lifting brackets 7 are provided. The multiple sets of lifting brackets 7 are arranged in a linear array from top to bottom. A tray 8 is provided above each set of lifting brackets 7. An X-shaped reinforcing rib 13 and a handrail rod 14 are fixedly connected between the two bearing columns 5. The number of X-shaped reinforcing ribs 13 is set to two, and the two X-shaped reinforcing ribs 13 are symmetrically distributed with respect to the handrail rod 14. A sealing gasket 15 is installed on the inner wall of the assembly groove 6, and the sealing gasket 15 is in interference fit with the bearing column 5. A cabinet door 16 is installed on the front of the cabinet 1. A sealing ring 17 is installed on the inner edge of the cabinet door 16. A visual window 18, a temperature gauge 19 and a pressure gauge 20 are installed on the surface of the cabinet door 16. The temperature gauge 19 and the pressure gauge 20 are symmetrically distributed with respect to the visual window 18. A vacuum pump 21 is installed on the top of the cabinet 1.

An air extraction pipe 22 is installed on the top of the vacuum pump 21, and one end of the air extraction pipe 22 extends into the drying chamber.

[0039] The working principle of the present utility model:

[0040] Refer to the attached Figure 1-7 description. When using the present utility model, first, the materials to be dried are evenly and neatly stacked on the tray 8, and then the tray 8 is placed on the lifting bracket 7 of the drying rack 2, ensuring that the limit sleeve 9 is accurately sleeved on the limit post 11, and at the same time, the clamping block 10 is also smoothly clamped into the card slot 12, so as to realize the rapid installation of the tray 8;

[0041] Open the cabinet door 16 on the front of the cabinet 1, and push the drying rack 2 loaded with materials into the cabinet 1 until the bearing column 5 is completely inserted into the assembly groove 6 at the bottom of the cabinet 1. By using the interference fit between the sealing gasket 15 on the inner wall of the assembly groove 6 and the bearing column 5, the sealing performance between the drying rack 2 and the cabinet 1 is ensured. Then close the cabinet door 16, and further enhance the sealing effect through the sealing ring 17 on the inner side of the cabinet door;

[0042] Start the vacuum pump 21, and extract the air inside the cabinet 1 through the air extraction pipe 22 until the inside of the drying chamber reaches the required vacuum state. Then start the cabinet 1 to heat, so that the materials are quickly dehydrated and dried in a vacuum environment;

[0043] After the materials are dried, turn off the heating system, let the cabinet 1 cool down naturally to a safe operating temperature, open the cabinet door 16, and the staff should wear heat-insulating gloves to protect their hands. Then firmly grasp the handrail rod 14 and pull the drying rack 2 out of the drying chamber. Since the base 3 of the drying rack 2 is located below the cabinet 1, the moving rollers 4 at the bottom of the base 3 can keep in contact with the ground. With the help of the moving rollers 4, the drying rack 2 can slide smoothly on the ground, and the drying rack is not likely to tip over during the operation, ensuring the safe transfer of the materials.
