Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figures 1-2As shown, a pressure-variable vacuum drying jar according to one embodiment of the present invention includes a drying jar body 1, which includes a tank body 101. A stirring motor 103 is installed on the top end face of the tank body 101. A cleaning port 1011 is opened on the side wall of the tank body 101. A cleaning window 102 is installed on one side wall of the cleaning window 102. A stirring assembly 2 is installed inside the tank body 101. An adjusting assembly 3 is installed on the side wall of the stirring assembly 2. A pair of inner wall cleaning assemblies 4 are installed on both sides of the stirring assembly 2. The inner wall cleaning assemblies 4 are used to clean the inner wall of the tank body 101. The adjusting assembly 3 moves the inner wall cleaning assemblies 4 to one side of the cleaning window 102, which facilitates the installation, replacement and cleaning of the inner wall cleaning assemblies 4 by the staff, thereby reducing the corrosion of the inside of the drying jar by the material and increasing the service life of the drying jar.

[0028] Furthermore, a sealing groove is provided on the side wall of the cleaning port 1011 of the tank body 101, and a sealing strip matching the sealing strip is installed on the side wall of the cleaning window 102, thereby ensuring the airtightness of the inside of the tank body 101. At the same time, a transparent window is installed on the side wall of the cleaning window 102, which facilitates the staff to observe the working status of the stirring component 2, the adjusting component 3 and the inner wall cleaning component 4 inside the tank body 101, and also facilitates understanding of the drying status of the material.

[0029] like Figure 2 and Figure 4 As shown, the stirring assembly 2 includes a fixed rod 201 and a movable rod 205. The fixed rod 201 has a first slot 203 and a second slot 204 on its side wall. A limiting rod 202 is integrally formed on the outer wall of the fixed rod 201. The movable rod 205 has an clearance groove 2051 matching the fixed rod 201 on its side wall, and a limiting groove 2052 matching the limiting rod 202 on its inner wall. The outer wall of the fixed rod 201 slides on the inner wall of the movable rod 205, and the outer wall of the limiting rod 202 slides on the inner wall of the limiting groove 2052. Connecting rods are integrally formed on the outer walls of both the fixed rod 201 and the movable rod 205, and both ends of the pair of connecting rods are fixedly connected to the side wall of the inner wall cleaning assembly 4.

[0030] like Figure 2 and Figure 5As shown, the adjustment component 3 is installed on the side wall of the moving rod 205. The adjustment component 3 includes a locking post 302, the side wall of which matches the first locking groove 203 and the second locking groove 204. The adjustment component 3 includes a support shell 301, which is integrally formed on the side wall of the moving rod 205. A limiting ring 3021 is integrally formed on the side wall of the locking post 302. A return spring 303 is fixedly connected to the side wall of the limiting ring 3021. One end of the return spring 303 is attached to the inner wall of one side of the support shell 301. The limiting ring 3021 slides and is attached to the inner wall of the support shell 301. When cleaning the movable rod 205 and the inner wall cleaning components 4 on both sides, first open the cleaning window 102, then manually pull one end of the locking pin 302, causing the outer wall of the limiting ring 3021 to slide on the inner wall of the support shell 301. After moving one side of the locking pin 302 away from the inner wall of the second slot 204, pull the locking pin 302 upward to move the movable rod 205 and the inner wall cleaning components 4 on both sides upward, so that the movable rod 205 slides on the outer wall of the fixed rod 201. When one side of the locking pin 302 slides upward to one side of the first slot 203, it engages with the inner wall of the first slot 203, thereby fixing the movable rod 205. This ensures that the height of the inner wall cleaning components 4 is located on one side of the cleaning window 102, facilitating the inspection and cleaning of the inner wall cleaning components 4.

[0031] like Figure 2 and Figure 3 As shown, the inner wall cleaning assembly 4 includes a cleaning rod 401. The side wall of the cleaning rod 401 is attached to the inner wall of the tank 101. Cleaning grooves 4011 are provided on the side wall of the cleaning rod 401, and stirring plates 402 are installed on the side wall of the cleaning rod 401. To ensure that the material is fully and evenly mixed during the drying process and to improve drying efficiency and quality, it is necessary to increase the stirring force of the material. In specific operation, the speed of the stirrer can be appropriately increased, and the stirring time can be extended, so that the material in the drying tank can be more fully agitated and mixed under the action of mechanical force.

[0032] A first mounting groove 4012 is provided on the side wall of the cleaning rod 401, and a second mounting groove 4013 is provided below the first mounting groove 4012. A mounting block 4021 matching the first mounting groove 4012 and the second mounting groove 4013 is provided on the side wall of the stirring plate 402. The outer wall of the stirring plate 402 and the mounting block 4021 are engaged with the inner wall of the first mounting groove 4012 and the second mounting groove 4013. When the stirring plate 402 is damaged and needs to be replaced, the operator only needs to slide the stirring plate 402 upwards along the second mounting groove 4013, causing the stirring plate 402 to slide the mounting block 4021 to one side of the first mounting groove 4012. Then, the operator pulls the stirring plate 402 outwards, causing the outer wall of the mounting block 4021 to move outwards along the inner wall of the first mounting groove 4012, thus removing the stirring plate 402.

[0033] During use, the cleaning window 102 is provided on the side wall of the drying tank body 1, and the movable structure design of the stirring component 2 is adjusted in conjunction with the adjustment component 3, which facilitates the replacement and cleaning of the stirring structure inside the drying tank. At the same time, it is convenient for the staff to observe the working status of the material, thereby greatly increasing the service life of the vacuum drying tank.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
