Technical Field

[0001] The utility model relates to the technical field of rotary kiln cleaning, in particular to an automatic cleaning structure for a driving wheel of a molybdenum oxide baking rotary kiln. Background Art

[0002] At present, molybdenum oxide baking mainly relies on rotary kiln. During the baking stage of molybdenum oxide, the rotary kiln needs to keep rotating to ensure uniform temperature in the kiln. At present, the power setting of the rotary kiln is often driven by the motor to drive the reducer, and then the reducer drives the power wheel to rotate, so that the power wheel engages with the drive wheel on the rotary kiln furnace body to rotate the rotary kiln.

[0003] However, the existing rotary kilns are limited by their size and are often arranged in open-air environments, which makes the driving wheels of the rotary kilns vulnerable to external environmental erosion. The bearings of most open-air rotary kilns will have some traces of modification. If the driving wheels of the rotary kilns are not cleaned regularly and in a timely manner, the rotation of the rotary kilns will be easily obstructed. In addition, since the driving wheels of the rotary kilns are often installed and supported based on the bearings, the space on both sides of the driving wheels of the rotary kilns is further limited. As a result, in daily maintenance, the rotary kilns often need to be manually cleaned under the turntable when the machine is stopped. In view of this, in-depth research was conducted on the above-mentioned issues, resulting in this case. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-4 The utility model provides an implementation scheme: in the specific implementation process, the existing molybdenum oxide baking mainly adopts a rotary kiln, and the power of the rotary kiln mainly comes from the meshing of the gear and the driving wheel. However, due to the large size of the rotary kiln, most rotary kilns are placed in an open-air environment. Therefore, dust and rainwater are easily accumulated in the driving wheel, which can easily cause the driving wheel to be dirty or rusted, resulting in poor meshing effect of the driving wheel, reducing the rotation effect, and thus causing the roasting efficiency of the rotary kiln to be reduced.

[0022] In view of the above problems, the present application discloses an automatic cleaning structure for the driving wheel of a molybdenum oxide baking rotary kiln. The rotary kiln is composed of a rotary kiln shell 1 as a furnace body, and a heater and a feeder are respectively connected on both sides of the rotary kiln. The material is added by the feeder and moves to one side of the heater, and the roasting is completed by the heater. The outer sleeve of the rotary kiln shell 1 is provided with a supporting wheel that cooperates with a bearing bush 2 installed on a support to play a supporting role for the rotary kiln.

[0023] At the same time, a supporting wheel is sleeved on the outside of the rotary furnace shell 1, and a pinion 4 is meshed with one side of the driving gear 3. The pinion 4 is driven to rotate by an external driving member, so that the pinion 4 is meshed with the driving gear 3, and the driving gear 3 drives the rotary kiln to rotate, which serves as the power source of the rotary kiln.

[0024] Furthermore, in order to improve the stability of the position operation of the driving gear 3, a bearing 2 is provided at the bottom of the driving gear 3 to support both sides of the driving gear 3 and play a supporting role. The bearing 2 supporting the driving gear 3 and the bearing 2 of the supporting wheel are the same type of structural bearing 2, and then a support rod 5 is connected to one side of the bearing 2, and a telescopic groove is provided on the support rod 5. A telescopic rod 6 is installed in the telescopic groove, and a cleaning brush 7 is connected to the end of the telescopic rod 6. The support rod 5 and the bearing 2 are movably connected through a pin shaft, and an angle adjustment component 8 is connected between the support rod 5 and the bearing 2;

[0025] In the specific implementation process, when the driving gear 3 needs to be cleaned, the distance between the support rod 5 and the driving gear 3 is shortened by the angle adjustment component 8, and the movable rotation of the support rod 5 is realized by the pin shaft arranged on the bearing bush 2, and then the height of the cleaning brush 7 can be adjusted by the telescopic rod 6, so that the cleaning brush 7 is aligned with the cleaning position, and during the rotation of the driving gear 3, the driving gear 3 is in contact with the cleaning brush 7, so that various debris on the surface of the driving gear 3 is cleaned up to keep the driving gear 3 clean;

[0026] Furthermore, a steering head 9 is provided on the bearing bush 2, and a telescopic hose 10 is connected to the steering head 9. A cleaning nozzle 11 is provided at one end of the telescopic hose 10, and the cleaning nozzle 11 is assembled at the head end of the telescopic rod 6. The other end of the steering head 9 penetrates the side wall surface of the bearing bush 2, and the telescopic hose 10 can be connected through the steering head 9;

[0027] During the specific implementation process, in order to improve the cleaning effect, the telescopic hose 10 is connected through the steering head 9, so that the cleaning nozzle 11 at the end of the telescopic hose 10 extends to the end of the telescopic rod 6. When the cleaning brush 7 is pulled closer, the cleaning nozzle 11 is synchronously pulled into the side wall of the bearing 2 at the other end through the steering head 9 to connect the external pipeline. A joint and a valve are set on the wall surface of the bearing 2. The valve is controlled to open and water is pumped in during cleaning. The steering head 9 is used to allow water to pass into the telescopic hose 10, and then the cleaning nozzle 11 sprays water onto the driving gear 3 to enhance the cleaning effect. The cleaning brush 7 is arranged on the side of the water outlet to scrape off the water.

[0028] As a preferred solution, further, a mounting groove 12 is opened on the bearing shell 2, and a pin shaft is arranged in the mounting groove 12 to be movably connected with the support rod 5. A conveying pipe 13 is connected to one side of the mounting groove 12 and passes through the steering head 9 to be connected. The end of the support rod 5 can be movably installed through the mounting groove 12.

[0029] As a preferred solution, further, the support wheel and the driving gear 3 are arranged in parallel or the driving gear 3 is sleeved on the support wheel. Both arrangements can achieve the technical effect. In the former case, the support wheel and the driving gear 3 are arranged with two bearings 2, and the support rod 5 and the steering head 9 are arranged on the bearing 2 on which the driving gear 3 is installed. In the latter case, the two share a bearing 2, and the support rod 5 and the steering head 9 are arranged on the bearing 2.

[0030] As a preferred solution, further, the telescopic slot is a cylindrical through slot, the telescopic rod 6 is a tubular structure, and a limiting ring 14 is provided at the end of the telescopic rod 6 to prevent the telescopic rod 6 from escaping from the telescopic slot.

[0031] As a preferred solution, further, according to the attached description Figure 1-3It can be known that the above-mentioned angle adjustment component 8 includes an adjusting motor 801, and an adjusting gear 802 is connected to the driving end of the adjusting motor 801. A synchronous gear 803 is arranged on one side of the support rod 5, and a transfer gear 804 is arranged between the adjusting gear 802 and the synchronous gear 803 to mesh. In the specific implementation process, the adjusting gear 802 is driven to rotate by the adjusting motor 801, and the transfer gear 804 is transmitted and meshed with the synchronous gear 803, so that the synchronous gear 803 rotates, and then the synchronous gear 803 drives the support rod 5 to rotate.

[0032] From the above, it can be generally known that the automatic cleaning structure of the driving wheel of the molybdenum oxide baking rotary kiln can clean the surface of the driving wheel by means of the support rod 5 and the telescopic rod 6 movably installed on one side of the bearing 2, which carry the cleaning brush 7 and contact the driving wheel of the rotary kiln. At the same time, the steering head 9 built into the bearing 2 is connected to the external pipeline to provide a cleaning agent, and the cleaning part is sprayed by the nozzle. The two cooperate to efficiently clean the driving wheel of the rotary kiln used for molybdenum oxide roasting.
