[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Example 1

[0031] Reference Figure 1-5 , which is the first embodiment of the utility model, provides a mixer for silica gel production, which includes two side bins 1, a lifting assembly 3 is arranged between the opposite surfaces of the two side bins 1, a stirring assembly 4 is installed at the fixed end of the lifting assembly 3, and the lifting assembly 3 drives the stirring assembly 4 to move vertically;

[0032] A positioning plate 5 is installed between the two side bins 1, and a mixing drum 2 is detachably installed in the positioning cavity of the positioning plate 5, and the mixing drum 2 is located directly below the mixing component 4. At the same time, the mixing end of the mixing component 4 stirs the inside of the mixing drum 2. A circle of universal wheels 21 are installed on the outer edge of the bottom of the mixing drum 2, and a handle frame 23 is welded at the upper position of one side of the outer wall of the mixing drum 2. Since a circle of universal wheels 21 are installed at the bottom end of the mixing drum 2, the mixing drum 2 can be moved by holding the handle frame 23, and the mixing drum 2 can be pushed into the interior of the semicircular cavity of the arc-shaped cavity block 51, so as to facilitate the pushing and moving of the mixing drum 2.

[0033] An arc-shaped cavity block 51 is welded on one side of the positioning plate 5 close to the mixing drum 2 , and a semicircular cavity matched with the mixing drum 2 is provided on one side of the arc-shaped cavity block 51 close to the mixing drum 2 .

[0034] An arc-shaped electromagnet 52 is installed on the top of the arc-shaped cavity block 51, and an arc-shaped iron bar 22 is fixedly installed on the peripheral surface of the mixing drum 2 and in the middle of the side away from the handle frame 23, and the arc-shaped electromagnet 52 and the arc-shaped iron bar 22 are magnetically adsorbed. The mixing drum 2 is installed in the mixing area of ​​the mixer in a detachable manner. The mixing drum 2 can be removed and away from the mixer before the silica gel unloading operation is performed, which is safe and fast. At the same time, two or more mixing drums 2 can be used in turn to reduce the downtime of the mixer and help improve the utilization rate of the mixer. At the same time, when the material inside the mixing drum 2 is stirred, the mixing drum 2 is magnetically adsorbed and fixed to avoid movement of the mixing drum 2 during stirring, thereby ensuring the stability of the mixer operation and preventing accidents. The installation method of electromagnetic magnetic adsorption is also convenient for quick disassembly of the mixing drum 2.

[0035] The lifting assembly 3 includes a linear motor 31 installed inside the side bin 1, and a vertical connecting plate 32 is fixedly installed on the movable end of the linear motor 31. The opposite surfaces of the side bins 1 on both sides are provided with connecting holes 11 for the vertical connecting plate 32 to pass through. A linkage block 33 is welded on the side of the vertical connecting plate 32 away from the side bin 1, and a fixed frame 34 is fixed between the opposite surfaces of the linkage blocks 33 on both sides.

[0036] Guide rails are installed on the opposite surfaces of the two side bins 1 and on both sides of the communicating opening 11. Two sliding blocks are installed on one side of the linkage block 33 close to the side bin 1, and the sliding blocks slide on the slide rails.

[0037] The fixed frame 34 can be driven by the linear motor 31 to move reciprocatingly, so that the stirring blades 45 can stir inside the mixing drum 2 while moving vertically up and down. The stirring blades 45 stir in different areas inside the mixing drum 2, thereby expanding the stirring area and area of ​​the stirring blades 45 and the material, making the material move in a disorderly manner inside the mixing drum 2, thereby improving the uniformity of material stirring.

[0038] The stirring assembly 4 includes a machine chamber 41, and side connecting plates 42 are installed on both sides of the peripheral surface of the machine chamber 41, and the side connecting plates 42 are fixed to the top of the fixed frame 34. A servo motor is installed at the center of the circle inside the fixed frame 34, and a stirring shaft 44 is installed at the driving end of the servo motor. Six stirring blades 45 are welded to the bottom end of the stirring shaft 44.

[0039] During use, when the mixing drum 2 is located inside the semicircular cavity, the magnetic surface of the arc-shaped electromagnet 52 and the arc-shaped iron bar 22 are in conflict with each other, and the arc-shaped electromagnet 52 is turned on to generate magnetism, and the arc-shaped electromagnet 52 and the arc-shaped iron bar 22 are magnetically adsorbed to achieve the positioning and fixing of the mixing drum 2;

[0040] After the raw materials are put into the mixing drum 2 according to the proportion, the servo motor drives the stirring blade 45 to rotate. When the linear motor 31 drives the fixed frame 34 to move downward, the stirring blade 45 enters the mixing drum 2 and stirs the materials inside the mixing drum 2 through the stirring blade 45.

[0041] Example 2

[0042] Reference Figure 1-5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0043] A cover 43 is provided at the bottom of the machine chamber 41 , and the size of the cover 43 is consistent with the size of the mixing drum 2 , and a circular hole for the mixing shaft 44 and the mixing blade 45 to pass through is provided at the center of the top of the cover 43 .

[0044] A connecting ring 431 is welded to the bottom of the interior of the machine chamber 41, and a T-shaped rod 432 is slidably installed on the connecting ring 431 through a circle of sliding holes opened on the connecting ring 431, and the cover 43 is fixed between the bottom ends of a circle of T-shaped rods 432, and the vertical end of the T-shaped rod 432 is located between the connecting ring 431 and the opposite surface of the cover 43, and a spring 433 is sleeved. When the machine chamber 41 is vertically raised or lowered, the cover 43 can remain stably closed on the top of the mixing drum 2 to cover the opening on the top of the mixing drum 2, so as to prevent the material from being thrown out from the inside of the mixing drum 2 during mixing, thereby avoiding the waste of raw materials on the one hand and preventing the raw materials from being thrown out and affecting the cleanliness of the environment on the other hand.

[0045] During use, when the machine chamber 41 is descending, the cover 43 first covers the top of the mixing drum 2. When the machine chamber 41 continues to descend, the cover 43 is inconvenient to maintain its position, and the machine chamber 41 continues to move downward through the compression of the spring 433 by the connecting ring 431. When the machine chamber 41 moves upward, under the elastic reset action of the spring 433, the distance between the cover 43 and the connecting ring 431 is enlarged. Therefore, when the machine chamber 41 is vertically raised or lowered, the cover 43 can remain stably closed on the top of the mixing drum 2 to cover the opening on the top of the mixing drum 2.

[0046] The remaining structures are the same as those of Example 1.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
