Description

Technical Field

[0001] This utility model belongs to the field of mixing pots, specifically relating to a crucible production mixing pot structure. Background Technology

[0002] Crucibles, as high-temperature containers, are widely used in metallurgy, chemical industry, and laboratories. The selection of raw materials directly affects the performance and lifespan of the crucible. Crucible production involves raw material proportioning, mixing, pressing, and firing. The mixing of raw materials directly affects the quality of the crucible firing. Traditionally, kneading pots are used to process and mix raw materials. However, existing kneading pots generally use double stirring blades with an S-shaped and twisted spiral shape. Although the twisted spiral shape can bring a certain conveying displacement effect during material mixing, the raw materials have a certain viscosity, which makes this conveying effect poor. This results in some unevenly mixed material accumulating at the edges of the stirring blades. In severe cases, the two stirring blades can mix two different proportions of raw materials. Furthermore, if too much raw material is added, the area affected by the stirring blades will be stirred, while the raw material not stirred by the stirring blades will slowly float to the top of the mixture. This situation usually occurs in the early and middle stages of mixing, requiring the mixing time to be extended to ensure the uniformity of the material mixing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a crucible production mixing pot structure, which is simple in structure, convenient and practical. The material is transported by the cooperation of the lower conveying screw and the upper conveying screw, so that the material at both ends of the mixing and kneading blades is transported to the center position or the material at the center position is quickly dispersed, thereby avoiding the situation of concentrated mixing of materials.

[0004] A crucible production mixing pot structure includes a mixing tank body, mixing blades, and a power unit. Two mixing blades are symmetrically installed in the mixing tank body and are driven by the power unit. The structure includes a lower conveying screw, an upper conveying screw, a material feeding device, and an adjusting cylinder. The lower and upper conveying screws are installed in the mixing tank body and driven by the mixing tank body, and are respectively located on the upper and lower sides between the two mixing blades. Two material feeding devices are installed on the mixing tank body and are respectively located above the two mixing blades. Two adjusting cylinders are respectively connected between the two material feeding devices. Both the lower and upper conveying screws include a forward conveying screw and a reverse conveying screw, with one end of the forward conveying screw connected to one end of the reverse conveying screw.

[0005] Preferably, a connecting rod connects the forward conveying screw and the reverse conveying screw of the lower conveying screw.

[0006] Preferably, the material feeding device includes a material feeding bar, a lifting cylinder, a lifting block, and a lifting frame. Both ends of the material feeding bar are connected to lifting columns. The two lifting cylinders are symmetrically connected to the side wall of the mixing tank and their piston rods are connected to the lifting block. The lifting frame is movably connected to the lifting block, and the lifting column is connected to the corresponding lifting frame.

[0007] Preferably, the lower side of the feed bar is tapered and has arc-shaped chamfers at both ends.

[0008] Preferably, a vibration motor is installed inside the feeding bar.

[0009] Beneficial effects:

[0010] (1) The present invention provides a crucible production mixing pot structure, which is simple, convenient and practical. By using the lower conveying screw and the upper conveying screw to transport materials, the materials in the two ends of the mixing and kneading blades are transported to the center position or the materials in the center position are quickly dispersed, so as to avoid the situation of concentrated mixing of materials.

[0011] (2) The crucible production mixing pot structure of this utility model uses a material feeding device to press down the material, so that the material floating on the upper surface during the mixing is squeezed into the mixing area, thereby reducing the mixing time.

Detailed Implementation

[0015] The embodiments of this utility model are further described below with reference to the accompanying drawings.

[0016] Example 1

[0017] like Figures 1 to 2As shown; a crucible production mixing pot structure includes a mixing tank body 1, mixing blades 3, and a power unit. Two mixing blades 3 are symmetrically installed inside the mixing tank body 1 and are drivenly connected to the power unit. The structure includes a lower conveying screw 2, an upper conveying screw 4, a material-driving device 5, and an adjusting cylinder 6. The lower conveying screw 2 and the upper conveying screw 4 are installed inside the mixing tank body 1 and are drivenly connected to the mixing tank body 1, respectively positioned on the upper and lower sides between the two mixing blades 3. Two material-driving devices 5 are installed on the mixing tank body 1 and are respectively located above the two mixing blades 3. Two adjusting cylinders 6 are respectively connected between the two material-driving devices 5. Both the lower conveying screw 2 and the upper conveying screw 4 include... The device comprises a forward conveying screw 7 and a reverse conveying screw 9, with one end of the forward conveying screw 7 connected to one end of the reverse conveying screw 9; a connecting rod 8 connects the forward conveying screw 7 and the reverse conveying screw 9 of the lower conveying screw 2; the material feeding device 5 includes a material feeding bar 51, a lifting cylinder 52, a lifting block 53, and a lifting frame 54; both ends of the material feeding bar 51 are connected to lifting columns 55; two lifting cylinders 52 are symmetrically connected to the side wall of the mixing tank 1, and their piston rods are connected to the lifting block 53; the lifting frame 54 is movably connected to the lifting block 53; and the lifting columns 55 are connected to the corresponding lifting frames 54; the lower side of the material feeding bar 51 is tapered and has arc-shaped chamfers at both ends; a vibration motor is installed inside the material feeding bar 51.

[0018] The mixing and kneading blades 3 and the lower and upper conveying screws 2 and 4 are rotated by a power unit. The mixing and kneading blades 3 agitate the material in the mixing tank 1. The material is conveyed and concentrated to the connecting rod 8 by the forward conveying screw 7 and the reverse conveying screw 9 of the lower conveying screw 2. The material agitated by the mixing and kneading blades 3 compresses the material concentrated at the connecting rod 8, causing the compressed material to rise to the area of ​​the upper conveying screw 4. Then, the forward and reverse conveying screws 7 and 9 of the upper conveying screw 4 disperse the concentrated material to the two ends between the two mixing and kneading blades 3, achieving a cyclic mixing effect. The lifting block 53 is raised and lowered by the lifting cylinder 52. The lowering block 53 drives the lifting frame 54 to rise and fall, the lifting frame 54 drives the lifting bar 51 to press the material in the mixing, so that the unmixed material floating on the surface of the mixture is pressed into the mixture, thus reducing the mixing time. The two adjusting cylinders 6 drive one end of the lifting column 55 of the two lifting devices 5 to move closer or further away, so that the angle of the lifting bar 51 is changed, thus changing the pressing angle. The lower side of the lifting bar 51 is set as a cone, so that the material moving in the mixing can be pressed into the mixed material along the cone surface. The vibrating motor vibrates the lifting bar 51, making the material mixing easier and more uniform.
