Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to a rotary kiln reducer regulating component. Background Art

[0002] A rotary kiln is a type of cement burning equipment that rotates to make the cement raw materials inside tumble and fully contact with the heat medium.

[0003] The rotary kiln reducer is a device used to drive the rotary kiln to rotate. It is also a speed reduction control component. It is usually composed of a motor, a reducer and related transmission components. It provides appropriate speed and torque so that the rotary kiln can rotate at a predetermined speed, and guides the high-speed rotational motion generated by the motor to be decelerated through the reducer, so that the rotary kiln can operate normally. It has a certain transmission ratio and stability to adapt to the different loads and working conditions required by the rotary kiln.

[0004] The reducer gearbox is rotatably connected to the reducer. Because it is used near the rotary kiln, there is a lot of dust. The dust easily adheres to the outer wall of the reducer gearbox and the reducer motor, which reduces the heat dissipation of the reducer gearbox and the reducer motor. The temperature of the lubrication inside the gearbox rises and the temperature of the motor rises, increasing the loss of internal equipment. For this reason, we propose a rotary kiln reducer control component to solve the existing problem. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, a rotary kiln reducer regulating component proposed by the utility model includes a reducer 1, a driven shaft 4, a grid frame 7, a rotary kiln 13, a bottom plate 14 and a filter cover 16. The reducer 1 is arranged at one end of the rotary kiln 13, and a driving gear 10 is arranged at the output end of the reducer 1. A gear ring 12 is sleeved on the outer wall of the rotary kiln 13, and the driving gear 10 and the gear ring 12 are meshed with each other. A bottom plate 14 is arranged at the lower end of the reducer 1, a driven shaft 4 is arranged on one side of the reducer 1, and a bracket 5 is arranged on one side of the upper end of the bottom plate 14. One end of the driven shaft 4 is rotatably inserted into the inside of the bracket 5, and a filter cover 16 is sleeved on the outer side of the reducer 1. The lower end of the filter cover 16 is connected to the bottom plate 14, and the upper end of the filter cover 16 is provided with a top cover 15. The top cover 15 and the filter cover 16 are rotatably installed through a hinge.

[0021] Based on the implementation steps of Example 1: the operation of the reducer 1 makes the driving gear 10 push the gear ring 12, and the rotary kiln 13 rotates. When the rotary kiln 13 rotates, the cement inside is tumbled and fired through the combustion medium. The process filter cover 16 is used to shield the outer wall of the reducer 1. The dust around the rotary kiln 13 is prevented from accumulating. The heat of the driving motor and the gearbox inside the reducer 1 is exchanged with the outside world, thereby avoiding dust accumulation, affecting the heat dissipation of the rotary kiln 13 reducer 1 and the regulating components, and increasing the loss problem.

[0022] like Figure 1-Figure 4 As shown, the utility model proposes a rotary kiln 13 reducer 1 regulating component compared to the first embodiment, and this embodiment also includes: the driven shaft 4 and the output end of the reducer 1 are both provided with mutually meshing bevel gears 9, the outer wall of the driven shaft 4 is provided with equidistantly distributed fan blades 8, the outer side of the fan blades 8 is sleeved with a grid frame 7, the driven shaft 4 and the grid frame 7 are rotatably installed through bearings, the lower end of the grid frame 7 is connected to the bottom plate 14, the outer wall of the driven shaft 4 is provided with a scraper 2, one end of the scraper 2 is provided with equidistantly distributed scrapers 3, a filter screen 6 is provided inside one end of the grid frame 7, and the outer wall of the output shaft of the reducer 1 is provided with a brush plate 11 corresponding to the gear ring 12.

[0023] In this embodiment, the driven shaft 4 rotates following the output shaft of the reducer 1 through the bevel gear 9, driving the fan blades 8 to rotate. The transmitted wind force dissipates the heat of the reducer 1, thereby improving the heat dissipation efficiency of the reducer 1. In order to prevent dust from adhering to the filter 6, the wind force acts on the meshing point of the driving gear 10 and the ring gear 12. The driven shaft 4 drives the scraper 2 to rotate, and the scraper 3 contacts the outer wall of the filter 6 to scrape off the dust adhering to the outer wall of the filter 6. At the same time, the brush plate 11 scrapes off foreign matter adhering to the ring gear 12, thereby reducing the wear of the ring gear 12 and the driving gear 10.
