Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a gravity-free automatic mixer. Background Art

[0002] The gravity-free mixer makes full use of the principle of convective mixing, that is, the material forms a flowing layer by the upward throwing movement in the mixer, generating instantaneous weightlessness, so as to reach the best mixing state. In the field of the flowing layer, the material moves axially under the action of specific overlapping blades, realizing mixing in an all-round range and forming a random optimal movement state.

[0003] When optimizing the existing gravity-free automatic mixer, most of them are reflected in enhancing the mixing structure and mixing multiple times to make the mixing treatment effect better. For example, the Chinese utility model patent with the application number CN03149931.7 discloses "A Solid Powder Continuous Mixer". In this device, mechanical mixing is realized by the stirring of the stirring blades in the powder premixing chamber, so that the powders to be mixed are pre-mixed more fully before entering the sprinkling plate. After being sprinkled, the powders are collected by gravity in the powder collection chamber. During the downward sliding and collection process of the powders, under the guiding action of the baffle plate, the powders are forced to pass through multiple baffle mixing processes of concentration, dispersion, concentration, and dispersion, so that the powders reach the purpose of mixing again during the flowing process.

[0004] Although the above-mentioned gravity-free automatic mixer has certain advantages in mixing multiple times and making the mixing treatment effect better, it still has certain disadvantages: if the mixed materials are directly placed into the mixing chamber at one time, the slurry plate needs to consume a large amount of power and requires a long mixing time to make the materials be mixed more evenly, resulting in a low mixing efficiency. Moreover, during the mixing operation, the upward throwing movement of the materials in the mixer forms a flowing layer, which will cause instantaneous weightlessness, resulting in the materials being easily splashed and splashing into the material feeding channel, which will also affect the mixing efficiency of the materials.

The mixing chamber 32 and the bin plate 31 are an integrated structure and are located inside it. The lower end of the paddle 34 is fixedly connected to the outer circumference of the bearing 33. The bearing 33 passes through the side end of the bin plate 31. One end of the bearing 33 is connected to the bearing seat 35 and is rotationally matched. The bearing seat 35 is installed at the right - hand side end position of the bin plate 31. One side end of the bearing 33 is connected to the output end of the drive motor 2 and is rotationally matched. There are multiple paddles 34 outside the bearing 33 and they are in a group for cooperative movement. There are two groups in the mixing chamber 32 and they rotate in opposite directions, which is beneficial to the convective mixing of materials.

[0029] Please refer to Figure 3-4, a gravity-free automatic mixer. The movable cover 4 includes a cover plate 41, a carrying handle 42, a convex plate 43, a feeding structure 44 and a sealing cover 45. The carrying handle 42 is installed on the upper end surface of the cover plate 41. The convex plate 43 is an integral structure with the cover plate 41. The feeding structure 44 is adjacently arranged on the side of the convex plate 43. The sealing cover 45 is snap-fitted and installed on the inner top of the feeding structure 44. The lower end of the feeding structure 44 penetrates through the cover plate 41. The feeding structure 44 includes a feeding chamber 441, a servo motor 442, a sliding plate 443 and a material control structure 444. The servo motor 442 is fixedly installed at a position slightly below the middle of one side end of the feeding chamber 441. The sliding plate 443 is fixedly arranged at a position slightly below the feeding chamber 441. The material control structure 444 is movably matched with the servo motor 442. The material control structure 444 moves above the sliding plate 443. The upper end surface of the cover plate 41 is connected to the connecting frame 8. The cover plate 41 is movably matched above the mixing bin 3 through the connecting frame 8. There are two feeding structures 44, and they are symmetrically arranged about the cover plate 41 in the left and right directions, providing feeding channels for different materials respectively. The feeding chamber 441 penetrates through the cover plate 41, and the feeding chamber 441 communicates above the mixing chamber 32. The output end of the servo motor 442 is connected with a screw bearing with a threaded surface, which is convenient for meshing with the material control structure 444 to drive its up and down displacement movement.

[0030] Please refer to Figure 5 , a gravity-free automatic mixer. The feeding chamber 441 includes a material control plate 4441, a screw 4442 and a cone block 4443. The bottom of the screw 4442 is fixedly connected to the upper end surface of the material control plate 4441. The lower end of the cone block 4443 penetrates through the upper end surface of the material control plate 4441 and is pressed into and rotates inside the material control plate 4441. The screw 4442 is meshed and matched with the servo motor 442. The material control plate 4441 moves above the sliding plate 443. The cone block 4443 is in a conical shape, and a turntable is installed at the bottom of the cone block 4443 embedded inside the material control plate 4441, and it can rotate self-driven in cooperation with it. The lifting displacement change of the material control plate 4441 generates an opening distance change with the sliding plate 443, which is convenient for the materials loaded in the feeding chamber 441 to be gradually released, improving the mixing efficiency.

[0031] In summary, cover the movable cover 4 above the mixing bin 3 to make the mixing chamber 32 airtight. Start the driving machine 2 to drive the bearing 33 to rotate, which drives the paddle 34 to turn. Discharge the materials to be mixed into the mixing chamber 32 from the feeding structure 44 respectively. The two groups of bin plates 31 and the mixing chamber 32 rotate in cooperation and in opposite directions. The materials are continuously thrown up and then fall in the mixing chamber 32 and are driven to rotate, which is beneficial to the convective mixing of the materials. Through the arranged feeding structure 44, when the mixing operation has not started, adjust the material control structure 444 to make one edge end abut against the sliding plate 443, so that the falling opening in the feeding chamber 441 is blocked. Personnel put the materials to be mixed into the feeding chamber 441, and then cover the sealing cover 45. After the operation is started, personnel can control the switch and speed of the servo motor 442, so that when its output end rotates, it can engage with the screw 4442, driving the material control plate 4441 to move upward or downward. When the material control plate 4441 moves upward, the distance between its edge end and the sliding plate 443 gradually increases, and the opening diameter gradually becomes larger. The materials in the feeding chamber 441 can slide along the sliding plate 443 into the mixing chamber 32 through the opening, thus completing the feeding of the materials in batches. Moreover, the sliding plates 443 in the relatively arranged feeding structures 44 also guide the materials to the middle of the mixing chamber 32 for mixing, effectively improving the mixing efficiency. During the mixing process, it also avoids the mixed materials in the mixing chamber 32 from being thrown up and splashing into the feeding chamber 441 again. By controlling the electric push rod 6, the opening and closing plate 7 changes its position intermittently below the mixing bin 3, so that the material falling opening of the mixing bin 3 is intermittently opened, ensuring that the materials in the mixing chamber 32 can be evenly mixed and then discharged in time.
