Description

Technical Field

[0001] The invention relates to a vacuum mixing tank. Background Art

[0002] At present, a mixing tank is a device used to evenly mix different materials, and is widely used in the fields of chemical industry and medicine. Most of the existing mixing tanks use rotating blades to stir the materials and achieve the purpose of evenly mixing the materials. For example, a Chinese patent with announcement number CN106215793B discloses an ultrasonic mixing vacuum stirring tank for natural ester insulating oil, in which the materials are evenly mixed by rotating the blades. However, there are some disadvantages in mixing materials by rotating the blades. Since the blades cannot reach all areas in the tank body, it is easy to form a mixing dead corner near the inner wall and bottom of the tank body. The fluidity of the materials in the mixing dead corners is poor, so the mixing speed is slow. In order to fully mix the materials in the mixing dead corners, it is often necessary to rotate the blades for a long time, which affects the mixing efficiency. Summary of the invention

[0061] The rotation axis 3 and the central axis 4 of the tank body 1 form an angle.

[0062] Specifically, the material to be mixed is first loaded into the inner cavity 2 of the tank body 1. Since the rotating shaft 3 forms an angle with the central axis 4 of the tank body 1, when the tank body 1 is driven to rotate around the rotating shaft 3, the material in the inner cavity 2 can be driven to flip and mix.

[0090] The locking elastic member 31 is installed between the left protrusion portion 39 and the right protrusion portion 40 and respectively abuts against the left protrusion portion 39 and the right protrusion portion 40. The locking elastic member 31 is used to drive the left protrusion portion 39 and the right protrusion portion 40 to move radially outward when the main body cover 28 is installed in the assembly position, thereby driving the left slider 29 and the right slider 30 to move radially outward respectively so that the left slider 29 is inserted into the left locking hole 37 and the right slider 30 is inserted into the right locking hole 38, thereby locking the position of the main body cover 28;

The driving mechanism is used to drive the valve plate component 59 to move to the second end of the discharge channel 60 so that the inner cavity 2 is connected to the discharge port 61 through the discharge channel 60. The driving mechanism is also used to drive the valve plate component 59 to move to the first end of the discharge channel 60 to block the communication between the inner cavity 2 and the discharge port 61. Specifically, when the valve plate component 59 moves to the second end of the discharge channel 60, the material in the inner cavity 2 can flow into the discharge channel 60 and then be discharged from the discharge port 61. When the valve plate component 59 moves to the first end of the discharge channel 60, the valve plate component 59 blocks the communication between the inner cavity 2 and the discharge port 61, so that the material cannot be discharged. In this embodiment, the discharge seat 58 is connected to the discharge barrel 57 through a flange, and the discharge barrel 57 is respectively connected to the inner tank wall 20, the middle tank wall 21 and the outer tank wall 22.

[0108] like Figure 2 , 7 As shown, the driving mechanism may include a transmission nut 62, a transmission screw 63 and a hand wheel 64;

[0109] The outer periphery of the valve plate component 59 is tightly slidably matched with the inner wall of the discharge channel 60;

[0110] The transmission nut 62 is rotatably connected to the discharge seat 58;

[0111] One end of the transmission screw 63 is fixedly connected to the valve plate component 59, and the transmission screw 63 is also threadedly matched with the transmission nut 62;

[0112] The hand wheel 64 is connected to the transmission nut 62 and is used to drive the transmission nut 62 to rotate, thereby driving the transmission screw 63 to move through threaded engagement and further driving the valve plate component 59 to move in the discharge channel 60 .

[0113] Specifically, the discharge channel 60 is further provided with a second accordion cover 65, which is sleeved on the outer side of the driving screw 63, one end of the second accordion cover 65 is connected to the valve plate component 59, and the other end of the second accordion cover 65 is connected to the discharge seat 58. More specifically, the valve plate component 59 includes a plate body connected to the driving screw 63 and a sealing rubber block connected to the plate body.

[0114] In this embodiment, the friction between the valve plate component 59 and the discharge channel 60 is relatively large due to the tight fit, and the friction between the valve plate component 59 and the discharge channel 60 can limit the rotation of the valve plate assembly and the drive screw 63 following the drive nut 62. Of course, in some embodiments, the valve plate assembly can also be set to a square or oval shape to limit the rotation of the valve plate assembly and the drive screw 63.

[0115] To summarize, firstly, the material to be mixed is loaded into the inner cavity 2 of the tank body 1. Since the rotating shaft 3 forms an angle with the central axis 4 of the tank body 1, when the tank body 1 is driven to rotate around the rotating shaft 3, the material in the inner cavity 2 can be driven to flip and mix. The rotation of the tank body 1 around the rotating shaft 3 drives the material in the inner cavity 2 to flip and mix, and there is no mixing dead angle. The material can be quickly and evenly mixed, thereby improving the mixing efficiency, saving the time for fully mixing the materials, and being more efficient and safer.

[0116] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
