[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0022] like Figure 1-2As shown, the utility model provides a spliced ​​horizontal mixer, including a mixing tank 100, a main shaft 200 and a spiral agitator 300, the main shaft 200 is coaxially and rotatably arranged in the mixing tank 100, the spiral agitator 300 includes a plurality of connecting blocks 310 and a plurality of stirring rods 320, the plurality of connecting blocks 310 and the plurality of stirring rods 320 are arranged alternately in sequence along a spiral line with the main shaft 200 as the center line, the plurality of connecting blocks 310 are connected to the main shaft 200, and two adjacent connecting blocks 310 are connected via the stirring rod 320, and the plurality of connecting blocks 310 and the plurality of stirring rods 320 form a spiral stirring structure.

[0023] During implementation, a plurality of connecting blocks 310 and a plurality of stirring rods 320 which are arranged in sequence along a spiral line with the main shaft 200 as the center line can be spliced ​​to form a spiral stirring structure. Compared with an integrated spiral structure, the manufacturing process of a single part is simple, thereby reducing the manufacturing cost.

[0024] The stirring tank 100 in this embodiment is a horizontal tank structure, and the main shaft 200 is coaxially and rotatably disposed in the stirring tank 100 to drive the spiral stirrer 300 connected thereto to move.

[0025] A feed hopper 110 is installed on the top of the mixing tank 100 to facilitate the introduction of materials into it. At the same time, a discharge port is formed at the bottom of the mixing tank 100, and a valve is installed at the discharge port to facilitate the discharge of materials. The side wall of the mixing tank 100 can be equipped with a motor 210 and a reducer, which are connected to one end of the main shaft 200 to drive the main shaft 200 to rotate.

[0026] The spiral agitator 300 in this embodiment is a spliced ​​structure, which is composed of multiple parts units, thereby reducing the cost of the spiral structure. Specifically, the spiral agitator 300 includes multiple connecting blocks 310 and multiple stirring rods 320. The multiple connecting blocks 310 and the multiple stirring rods 320 are arranged in sequence along a spiral line with the main shaft 200 as the center line. The multiple connecting blocks 310 are connected to the main shaft 200, and two adjacent connecting blocks 310 are connected via the stirring rods 320. The multiple connecting blocks 310 and the multiple stirring rods 320 form a spiral stirring structure.

[0027] In one embodiment, the stirring rod 320 is a straight rod.

[0028] In another embodiment, the stirring rod 320 is an arc-shaped rod and is bent along the extending direction of the spiral line.

[0029] It is understandable that the stirring rod 320 may also be in a V-shape or other shapes, and its main function is to connect two adjacent connecting blocks 310 to form a part of the spiral stirring structure.

[0030] In one embodiment, the connection block 310 and the stirring rod 320 are detachably connected. Meanwhile, the connection block 310 is connected to the main shaft 200 via a connecting rod 330 .

[0031] like Figure 3 As shown, in order to facilitate the connection between the connecting block 310, the stirring rod 320 and the connecting rod 330, the present embodiment also includes a connecting screw 350 and a connecting nut 360. A groove 311 is formed on the connecting block 310 close to the main shaft 200. One end of the connecting rod 330 is embedded in the groove 311, and the other end of the connecting rod 330 is connected to the main shaft 200. The free end of the connecting screw 350 passes through the connecting block 310 and the connecting rod 330 in the groove 311 in turn and is connected to the connecting nut 360.

[0032] In order to improve the stability of the connection between the stirring rod 320 and the connecting block 310, after the connecting screw 350 and the connecting nut 360 are installed, welding is performed at the connection between the connecting screw 350 and the connecting nut 360.

[0033] In order to achieve the connection between the connecting rod 330 and the main shaft 200, this embodiment also includes a connecting sleeve 340, which is sleeved on the main shaft 200 and connected to the threaded hole formed on the main shaft 200 via a fixing screw. The connecting rod 330 is fixedly connected to the outer wall of the connecting sleeve 340.

[0034] It is understandable that the connection between the connecting block 310, the stirring rod 320, the connecting rod 330 and the main shaft 200 may also be connected in other forms such as welding, as long as they can be spliced ​​to form a spiral stirring structure.

[0035] In one embodiment, the stirring rod 320 is flat, and the thickness of the stirring rod 320 along the length direction of the main shaft 200 is smaller than the thickness of the stirring rod 320 along the direction perpendicular to the main shaft 200, so as to facilitate driving the material to move along the spiral direction.

[0036] In one embodiment, the connection blocks 310 are attached to the inner wall of the mixing tank 100 and arranged at intervals.

[0037] like Figure 4 As shown, in one embodiment, there are multiple spiral agitators 300 to form multiple coaxially arranged spiral agitation structures.

[0038] It is understandable that the inner diameters of the two spiral agitators 300 can be set to be the same or different. Similarly, the rotation directions of the two spiral agitators 300 can be the same or opposite.

[0039] When the inner diameters are the same, the two spiral agitators 300 are set in opposite directions to alternately lift the materials inside the mixing tank 100. When the inner diameters are different, the outer wall of one of the spiral agitators 300 should be set close to the inner wall of the mixing tank 100 to lift the materials in the outer circle, and the other spiral agitator 300 has a smaller diameter to lift the materials in the inner circle to achieve the function of uniform stirring.

[0040] It should be noted that the multiple connection blocks 310 in the two spiral agitators 300 can share a connection sleeve 340 .

[0041] Compared with the prior art: by setting up a plurality of connecting blocks 310 and a plurality of stirring rods 320 which are arranged in sequence along a spiral line with the main shaft 200 as the center line, a spiral stirring structure can be spliced ​​to form. Compared with the integrated spiral structure, the manufacturing process of a single part is simple, and the manufacturing cost is reduced.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
