Description

Technical Field

[0001] The utility model relates to the technical field of rotary kiln supporting wheels, in particular to a large-scale kiln rotary kiln supporting wheel assembly. Background Art

[0002] As an important part of the rotary kiln, the supporting wheel of the rotary kiln undertakes the key task of supporting and rotating the kiln body. The basic components of the supporting wheel include the wheel body, wheel rim, wheel axle, bearing and protective device. Through reasonable design and material selection, the supporting wheel can bear the weight of the kiln body, transmit the rotation force, adjust the tilt angle, and protect the normal operation of the bearing and wheel axle.

[0003] The patent specification with the announcement number CN216139372U discloses a high temperature and wear-resistant large kiln rotary kiln support wheel assembly, including a high temperature and wear-resistant large kiln rotary kiln support wheel assembly, including a support wheel body, a platform and a rotating shaft, both sides of the support wheel body are provided with a heat dissipation structure, and the inner side wall of the support wheel body is provided with a wear-resistant structure. The utility model is provided with a refrigeration mechanism, when the servo motor is started, the threaded rod rotates, and the threaded sleeve moves up and down through the action of thread engagement, so the cooling cotton fixed above the threaded sleeve also moves up and down accordingly, and the cooling cotton is stained with the coolant in the cooling liquid cylinder by lifting and lowering the cooling cotton to continuously cool the working support wheel body, ensuring that the support wheel body is not continuously in a high temperature state, thereby increasing the service life of the rotary kiln support wheel assembly.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed high-temperature-resistant and wear-resistant large-scale kiln rotary kiln support wheel assembly has the following problems: since no cleaning mechanism is provided on the cooling cotton, the rotary kiln support wheel and the wheel belt repeatedly rotate and rub, which inevitably produces iron filings due to friction. Once the iron filings adhere to the cooling cotton, when the support wheel is cooled, the iron filings come into contact with the support wheel, causing wear of the support wheel and affecting the normal use of the support wheel. In view of this, a large-scale kiln rotary kiln support wheel assembly is now provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a large-scale kiln rotary kiln supporting wheel assembly.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a large-scale kiln rotary kiln support wheel assembly, including a fixed bracket, a coolant storage tank is opened inside the fixed bracket, and cooling cotton is installed inside the coolant storage tank, a lifting cylinder is installed below the cooling cotton, and the cooling cotton is connected to the telescopic end of the lifting cylinder, a wheel axle is installed above the coolant storage tank, and a support wheel body is fixed outside the wheel axle, the cooling cotton is lifted and lowered in the coolant storage tank by the lifting cylinder, and can contact with the support wheel body after rising, so as to cool down the support wheel body, a cleaning mechanism is installed above the cooling cotton, and the cooling cotton is connected to the telescopic end of the lifting cylinder. The cleaning mechanism includes a cleaning plate installed above the cooling cotton, and a number of cleaning brushes are evenly distributed at equal intervals on the bottom of the cleaning plate. Limiting sliders are fixed on both ends of the cleaning plate, and a limiting slide groove is provided at the connection between the limiting slider and the coolant storage tank. The interior of the limiting slider is connected with an adjusting screw through a screw nut, and the front end of the adjusting screw is connected to the power output end of the screw motor through a flange. By arranging a cleaning mechanism that can move back and forth above the cooling cotton, the cooling cotton can be cleaned, and iron filings and other debris that fall on the cooling cotton can be swept away, thereby avoiding wear of the support wheel body due to iron filings and other debris on the cooling cotton.

[0007] As a further description of the above technical solution: a filter is installed at the front end of the coolant storage tank, and the filter can filter the coolant in the coolant storage tank.

[0008] As a further description of the above technical solution: a spray pipe bracket is fixedly installed on the front end of the fixed bracket by bolts, and a spray head is provided on the side of the spray pipe bracket close to the roller body, and the water outlet direction of the spray head is perpendicular to the roller body. The coolant can be sprayed to the roller body through the spray head, thereby further cooling the roller body and improving the cooling effect.

[0009] As a further description of the above technical solution: a connecting pipe is installed between the spray head and the coolant storage tank, and an extraction pump is provided below the spray head. The extraction pump is fixed on the top of the fixed bracket by bolts, and the extraction pump can extract the coolant in the coolant storage tank.

The coolant is transmitted to the spray head through the connecting pipe and then sprayed out through the spray head.

[0011] As a further description of the above technical solution: the size of the cooling cotton is smaller than the top size of the coolant storage tank, and the cooling cotton is lifted and lowered in the coolant storage tank by a lifting cylinder. Due to the small size of the cooling cotton, there is a certain gap between it and the wall of the coolant storage tank, so that debris on the cooling cotton can be swept into the coolant storage tank.

[0012] As a further description of the above technical solution: the thickness of the cleaning plate is smaller than the gap between the cooling cotton and the coolant storage tank. After the cleaning plate moves backward and is close to the coolant storage tank, it will not block the cooling cotton from moving upward.

[0013] The utility model has the following beneficial effects:

[0014] The utility model designs a large-scale kiln rotary kiln supporting wheel assembly. The provided screw motor drives the adjusting screw to rotate, which can drive the cleaning mechanism to move forward and backward, and then drives the cleaning plate to slide. The cooling cotton is cleaned by the cleaning brush, and the iron filings and other debris falling on the cooling cotton are swept away, thereby avoiding the wear of the supporting wheel body due to the iron filings and other debris on the cooling cotton.

[0023] As a further implementation scheme of the above technical scheme: a filter screen 9 is installed at the front end of the coolant storage tank 4 , and the filter screen 9 can filter the coolant in the coolant storage tank 4 .

[0024] As a further implementation scheme of the above technical scheme: a spray pipe bracket 5 is fixedly installed on the front end of the fixed bracket 3 by bolts, and a spray head 7 is provided on the side of the spray pipe bracket 5 close to the roller body 1, and the water outlet direction of the spray head 7 is perpendicular to the roller body 1. The coolant can be sprayed to the roller body 1 through the spray head 7, so as to further cool down the roller body 1 and improve the cooling effect.

[0025] As a further implementation scheme of the above technical scheme: a connecting pipe 8 is installed between the spray head 7 and the coolant storage tank 4, and an extraction pump 6 is provided below the spray head 7. The extraction pump 6 is fixedly installed above the fixed bracket 3 by bolts. The extraction pump 6 can extract the coolant in the coolant storage tank 4.

[0026] As a further implementation scheme of the above technical scheme: the connecting pipe 8 is connected to the coolant storage tank 4 through the filter 9 and the extraction pump 6, and the connecting pipe 8 is connected to the spray head 7. The coolant is transmitted to the spray head 7 through the connecting pipe 8 and then sprayed out through the spray head 7.

[0027] During specific implementation, the extraction pump 6 extracts the coolant in the coolant storage tank 4, and the coolant enters the connecting pipe 8 after being filtered through the filter screen 9. The connecting pipe 8 transmits the coolant to the spray head 7 and then sprays the coolant onto the surface of the roller body 1, thereby cooling the roller body 1 and improving the cooling effect.

When the cleaning brush 12 contacts the cooling cotton 16, the cooling cotton 16 is in a soaked state. When the supporting roller body 1 rotates driven by the wheel shaft 2, the lifting cylinder 17 is started at the same time. The lifting cylinder 17 pushes the cooling cotton 16 to move upward until it contacts the cleaning brush 12. Then the screw motor 10 is started. The screw motor 10 drives the adjusting screw 13 to rotate under the action of the screw nut, driving the cleaning plate 11 to move back and forth. At this time, the limiting slider 15 on the cleaning plate 11 slides in the limiting slide groove 14. At this time, the cleaning brush 12 contacts with the cooling cotton 16, and the iron filings and other debris on the cooling cotton 16 are swept into the coolant storage tank 4. After the cleaning plate 11 is close to the tank wall of the coolant storage tank 4, the cooling cotton 16 continues to rise and contacts with the supporting roller body 1 to cool the supporting roller body 1.
