Description

Technical Field

[0001] This utility model belongs to the field of bearing lubrication technology, specifically relating to a structure for adding lubricating grease to the scraper bearing of a flotation machine. Background Technology

[0002] Flotation is the most commonly used separation process in the mineral processing industry. Currently, the mineral processing department has 40 JJF-type flotation machines, 19 KYF-type flotation machines, and 10 BF-type flotation machines, mainly used to remove harmful elements such as fluorine and sulfur from iron ore. After the upgrade of the three-stage reverse flotation equipment, the lubrication method for the flotation machine scrapers has changed from water lubrication to glycerin lubrication. Regular lubrication is required, and the following problems exist:

[0003] The existing bearing bushes are fixed and cannot be disassembled, making maintenance inconvenient. The current method of adding oil involves using a wooden board to pick up glycerin and then applying it to the bearing bush, which is inconvenient. In addition, the scraper needs to be stopped and a power outage sign needs to be changed when adding oil, which is time-consuming and inefficient. Stopping the scraper also has a certain impact on the flotation operation indicators, which is not conducive to the stable and smooth operation of the production process.

[0004] In view of the above factors, this utility model provides a structure for adding lubricating grease to the scraper bearing of a flotation machine, which can add oil without stopping the machine. On the one hand, it ensures the continuity of the normal process and avoids fluctuations in indicators, and on the other hand, it improves the convenience of operation and reduces safety risks. Utility Model Content

[0005] The purpose of this invention is to provide a structure for adding lubricating grease to the scraper bearing of a flotation machine, so as to solve the problems mentioned in the background art.

[0006] The purpose of this utility model is achieved through the following technical solution: a structure for adding lubricating grease to the scraper bearing of a flotation machine, including an upper bearing seat and a lower bearing seat detachably connected to the upper bearing seat, wherein the lower bearing seat is detachably connected to the crossbeam supports on both sides of the flotation machine.

[0007] The upper bearing seat is provided with a lubricating grease filling hole, which extends into the upper bearing seat but does not penetrate the upper bearing seat.

[0008] Symmetrical oil grooves are provided on both sides of the lubricating grease filling hole on the upper bearing seat;

[0009] The lubricating grease filling hole on the upper bearing seat is detachably connected to the filling pipe, and one end of the filling pipe is fixed to the outside of the safety railing of the flotation machine.

[0010] Furthermore, the oil groove is a double oil groove structure, and the double oil groove is arranged at an angle, with the double oil groove located at the center of the cross-section of the upper bearing seat.

[0011] Furthermore, the double oil grooves extend through the upper bearing seat, and the double oil grooves are connected to the lubricating grease filling hole.

[0012] Furthermore, the lubricating grease filling hole forms a buffer channel within the upper bearing seat, and the buffer channel is a hollow rectangular structure.

[0013] Furthermore, a grease filter tube is provided on the lubricating grease filling hole, and the grease filter tube is connected to the lubricating grease filling hole by a thread, with the other end of the grease filter tube connected to the filling tube.

[0014] Furthermore, a vertical channel is provided on the arc-shaped surface of the lower bearing seat, and the vertical channel extends downward to the oil storage cavity at the bottom of the lower bearing seat.

[0015] Furthermore, at least two sets of vertical channels are provided, and the bottom of the oil storage chamber is connected to an air pipe. The air pipe is a metal pipe structure and is equipped with an electrically controlled valve.

[0016] Furthermore, an external air pump is connected to the side of the air pipe away from the oil storage chamber.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features an oil storage chamber. During filling, excess grease flows into the oil storage chamber as the roller rotates. To facilitate the use of the oil storage chamber, an air pump is used to pressurize the chamber and allow the lubricating oil to contact the roller inside the bearing bush through a vertical channel. An external air pump is connected to the side of the air pipe away from the oil storage chamber. By setting up the air pump, backflushing can be performed during use, blowing the lubricating oil in the oil storage chamber upward through the vertical pipe, allowing the lubricating oil to contact the roller.

[0019] This utility model is equipped with a grease filter tube to filter the lubricating oil that needs to be added. The upper bearing seat and the lower bearing seat are detachably connected by bolts, which facilitates disassembly and maintenance.

[0020] This invention allows for oil filling without shutting down the machine, ensuring the continuity of the normal process and avoiding fluctuations in indicators, while also improving operational convenience and reducing safety risks. Attached Figure Description
