DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] See also Figure 1-4A zinc oxide calcining kiln transmission gear lubrication anti-seepage device includes a drive gear 9 installed on a rotary kiln gear 10 and meshing with the rotary kiln gear 10. The contact surface of the rotary kiln gear 10 and the drive gear 9 is subjected to a large force during operation. Not only sufficient lubrication but also the quality of the lubricating oil must be ensured. Therefore, the amount of oil hanging on the rotary kiln gear 10 is large. During the rotation process, part of the lubricating oil will be thrown out from the rotary kiln gear 10, thereby causing pollution to the surrounding equipment and the ground, and also causing a large waste of lubricating oil. For this reason, the present application is proposed. Specifically, the drive gear 9 is an existing The gear set driving the rotary kiln can be specifically referred to the prior art. An annular oil groove 3 is arranged around the rotary kiln gear 10. The annular oil groove 3 is arranged around the rotary kiln gear 10 to provide all-round protection for the rotary kiln gear 10. During installation, the contact between the annular oil groove 3 and the rotary kiln gear 10 should be avoided. Therefore, a light aluminum alloy material can be selected for preparation. During the supporting process, a U-shaped bracket 1 supporting the annular oil groove 3 is arranged at the bottom of the annular oil groove 3 to support and fix the annular oil groove 3. The specific U-shaped bracket 1 can be installed on the ground or on a fixed support of the rotary kiln.

[0027] An oil barrel 7 is also provided at the bottom of the annular oil groove 3, and the lubricating oil flowing into the annular oil groove 3 can be directly discharged. Specifically, the oil barrel 7 and the bottom of the annular oil groove 3 are connected by a reflux pipe 6, and the lubricating oil in the annular oil groove 3 all flows into the bottom, and under the action of gravity, flows into the oil barrel 7 through the reflux pipe 6 for reuse. A notch is also provided on one side of the annular oil groove 3, and the driving gear 9 is located at the notch. It is worth noting that the rotary kiln rotates to the side away from the notch. Therefore, the lubricating oil is mainly in the annular oil groove 3 away from the notch. Therefore, less lubricating oil flows out of the notch side, and the top of the notch is located above the driving gear 9. Therefore, the lubricating oil will also flow to the driving gear 9 without causing waste. In the present application, the bottom of the driving gear 9 and the notch away from the notch An L-shaped oil groove 8 is provided on one side of the rotary kiln gear 10. The L-shaped oil groove 8 and the oil barrel 7 are connected by an oil supply pipe 5. The oil supply pipe 5 is connected to an oil pump. When the present application is specifically installed, it is necessary to ensure that the lubricating oil in the L-shaped oil groove 8 can immerse all the teeth in the lubricating oil during the rotation of the driving gear 9, that is, all the teeth of the driving gear 9 can be lubricated to ensure lubrication at the meshing position and improve the lubrication effect. Since the rotation speed of the driving gear 9 is relatively fast, the L-shaped oil groove 8 collects the lubricating oil thrown out from the side away from the rotary kiln and makes it flow into the L-shaped oil groove 8. The other side in contact with the rotary kiln gear 10 can throw the lubricating oil onto the rotary kiln gear 10 without causing waste, thereby completing the lubrication of the gear set and the recovery of the lubricating oil.

[0028] In the utility model, a plurality of mounting plates 4 are fixed on one side of the annular oil groove 3, a plurality of supporting plates 2 corresponding to the mounting plates 4 are fixed on the U-shaped bracket 1, corresponding holes are provided on the mounting plates 4 and the supporting plates 2, and the supporting plates 2 and the mounting plates 4 are fixed by bolts. During installation, after the U-shaped bracket 1 is fixed, other structures can be quickly installed, and the annular oil groove 3 can also be cleaned regularly.

[0029] In some embodiments, in order to improve the installation efficiency of the annular oil groove 3, the annular oil groove 3 is composed of two oil retaining grooves 31 located at the top of the rotary kiln gear 10 and a reflux groove 32 located at the bottom of the rotary kiln gear 10. The two oil retaining grooves 31 and the reflux groove 32 are enclosed to form the annular oil groove 3. The oil retaining groove 31 and the reflux groove 32 are respectively fixed on the U-shaped bracket 1. When disassembling, they can be disassembled separately, thereby improving the installation efficiency and facilitating the quick installation of the annular oil groove 3 on the rotary kiln.

[0030] In the present embodiment, an oil guide plate 34 is fixed on the inner side of one end of the oil baffle groove 31 at the bottom. The oil guide plate 34 of the oil baffle groove 31 on the side away from the notch extends into the reflux groove 32. The oil guide plate 34 is U-shaped and fixed to the inner wall of the oil baffle groove 31. It can make all the lubricating oil in the oil baffle groove 31 flow into the reflux groove 32 at the bottom to prevent the lubricating oil from flowing out along the gap between the oil baffle groove 31 and the reflux groove 32. The oil guide plate 34 on the reflux groove 32 close to the notch is located above the driving gear 9 to guide the lubricating oil to the driving gear 9. In the present embodiment, the oil guide plate 34 can be made of a plastic plate.

[0031] In this embodiment, the tops of the two oil retaining grooves 31 are connected by a guardrail buckle 33. After the annular oil groove is fixed, the two oil retaining grooves 31 can be fixed by the guardrail buckle 33 so that the two oil retaining grooves 31 support each other.

[0032] In some embodiments, a filter screen 11 is provided in the oil barrel 7. Since the oil barrel 7 has a large diameter, it has a better filtering function. The specific filter screen 11 can be designed to be an inverted cone. The filter screen 11 can be specifically filtered using filter paper to filter iron filings and other impurities in the lubricating oil to improve the quality of the lubricating oil. Specifically, the reflux pipe 6 is located on the upper part of the filter screen 11 to filter the refluxed lubricating oil. The oil supply pipe 5 passes through the filter screen 11 and is located at the bottom of the oil barrel 7. The lubricating oil entering the L-shaped oil tank is all filtered lubricating oil, thereby reducing the wear at the meshing point and increasing the service life of the gear.

[0033] In the utility model, a separate bracket can be provided to support the L-shaped oil groove 8, or the L-shaped oil groove 8 can be fixed on one of the support plates 2 for lubricating the drive gear 9. In the specific lubrication of the L-shaped oil groove 8, the liquid level of the L-shaped oil groove 8 is located at the 1 / 2-2 / 3 position, which can be specifically detected by an oil level gauge to ensure the liquid level of the lubricating oil.

[0034] It can be seen from the above technical scheme that when in use, the present application shields the lubricating oil thrown out by the rotary kiln gear 10 through the annular oil groove 3 during the operation of the rotary kiln gear 10, and the lubricating oil flows to the bottom of the annular oil groove 3, and then flows to the oil barrel 7 through the reflux pipe 6. In the lubrication process of the rotary kiln gear 10, the present application sends the lubricating oil to the L-shaped oil groove 8, and a part of the driving gear 9 is immersed in the lubricating oil in the L-shaped oil groove 8, and the driving gear 9 is fully lubricated, thereby achieving effective lubrication of the transmission position. The L-shaped oil groove 8 can not only store the lubricating oil, but also collect the lubricating oil thrown out by the driving gear 9, and collect the lubricating oil thrown out by the rotary kiln gear 10 and the driving gear 9 together with the annular oil groove 3.
