Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, specifically a rotary kiln tube positioning wheel device. Background Technology

[0002] Rotary kilns are widely used in industrial production for processes such as calcination and roasting of materials. The furnace tube is a key component of the rotary kiln, playing a crucial role in its operation. It must maintain stable rotation and accurate positioning to ensure proper material handling and continuous production. However, existing rotary kiln furnace tubes often exhibit axial misalignment ("back-and-forth swaying") during rotation. This can be caused by various factors, such as slight vibrations of the kiln body, uneven weight distribution within the furnace tube, and external environmental interference. Once the furnace tube misaligns, it not only affects the normal flow of material within the tube, leading to uneven material handling, but it can also collide with surrounding equipment, causing the kiln head seal to jam or be damaged, reducing the service life of the rotary kiln, increasing maintenance costs, and increasing the risk of production interruptions. Utility Model Content

[0003] The purpose of this utility model is to disclose a rotary kiln positioning wheel device to solve the axial displacement problem of rotary kilns in the above-mentioned background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rotary kiln tube positioning wheel device includes a positioning wheel mounting plate vertically arranged relative to the rotary kiln support roller bracket. The rotary kiln support roller bracket has support rollers installed at both ends that roll in contact with the front of the rotary kiln tube retaining ring. Two positioning wheel mounting seats are symmetrically installed on the positioning wheel mounting plate, and the mounting holes of the positioning wheel mounting seats are through holes. The positioning wheel mounting seats are equipped with positioning wheels that roll in contact with the side of the rotary kiln tube retaining ring.

[0006] This utility model has the following beneficial effects:

[0007] By adding a positioning wheel mounting plate and a positioning wheel mounting seat to the support roller bracket, the drawback of existing rotary kilns having only support rollers but no positioning wheels is solved. The positioning wheels, which are rotatably mounted on the positioning wheel mounting seats, are engaged with both sides of the rotary kiln tube retaining ring, solving the problem of easy axial movement of the rotary kiln during operation. By adding an adjustment device, the distance between the two positioning wheel mounting seats can be adjusted, thereby adjusting the distance between the two positioning wheels to accommodate furnace tube retaining rings of different widths, ensuring that the two positioning wheels are always in contact with both sides of the rotary kiln tube retaining ring, thus improving positioning accuracy. Attached Figure Description

[0008] Figure 1 This is a top view of the structure of this utility model.

[0009] Figure 2 This is the main view of the structure of this utility model.

[0010] In the figure, 1-rotary kiln support roller bracket, 2-positioning wheel mounting plate, 3-rotary kiln tube retaining ring, 4-support roller, 5-positioning wheel mounting seat, 6-positioning wheel, 7-adjusting device, 701-adjusting plate, 702-adjusting screw. Detailed Implementation

[0011] The present invention will be further explained below with reference to the accompanying drawings.

[0012] like Figure 1 As shown, a rotary kiln tube positioning wheel device includes a positioning wheel mounting plate 2 vertically arranged relative to the rotary kiln support roller bracket 1. The positioning wheel mounting plate 2 is welded and fixed to the rotary kiln support roller bracket 1. Support rollers 4 are installed at both ends of the rotary kiln support roller bracket 1, which roll in contact with the front of the rotary kiln tube retaining ring 3. Two positioning wheel mounting seats 5 are symmetrically installed on the positioning wheel mounting plate 2, and the mounting holes of the positioning wheel mounting seats 5 are elongated through holes, with the through holes oriented in the direction of the two positioning wheel mounting seats moving towards each other. Positioning wheels 6 are installed on the positioning wheel mounting seats 5, which roll in contact with the side of the rotary kiln tube retaining ring 3.

[0013] An adjustment device 7 is also provided on the positioning wheel mounting plate 2. This adjustment device includes an adjustment plate 701 fixed to the positioning wheel mounting plate 2, and an adjustment screw 702 threadedly connected to the adjustment plate 701. The adjustment screw 702 abuts against the positioning wheel mounting seat 5. By rotating the adjustment screw 702, the adjustment screw 702 pushes the two positioning wheel mounting seats 5 to move towards each other, ensuring that the two positioning wheels 6 contact the side of the rotary kiln tube retaining ring 3. The adjustment force is adjusted to ensure the positioning wheel limiting effect without jamming the rotary kiln tube retaining ring.

[0014] In summary, this utility model, by adding positioning wheels and a positioning wheel adjustment device, improves the adaptability of furnace tube retaining rings of different widths while ensuring that the two positioning wheels are always in contact with both sides of the rotary kiln furnace tube retaining ring, thus solving the problem of easy axial displacement of the rotary kiln furnace tube during operation.
