Description

Technical Field

[0001] The utility model belongs to the technical field of cooling sintering machine equipment, and in particular relates to a spray cooling device installed on a bearing bush seat. Background Art

[0002] In the steel smelting industry, the sintering process is one of the important production links in the entire process, and has extremely high requirements for equipment stability. However, in the actual production process, the equipment faces the challenge of high temperature environment on site, especially the star wheel bearing seat at the tail of the sintering machine. Since the equipment operates in a high temperature environment of more than 200 degrees for a long time, it puts extremely high requirements on the lubrication and durability of the bearing.

[0003] At present, for the lubrication and maintenance of the star wheel bearing, we use lithium-based grease for lubrication, but the fluidity of the grease often deteriorates and fails in high temperature environments, which in turn leads to increased wear of the bearing cage. This wear not only affects the service life of the bearing, but once it is worn to a certain extent, the bearing may lock, causing a sudden shutdown of the production line, seriously affecting production efficiency and product quality. To address this problem, the common practice in the industry is to plan shutdowns and replace worn bearings. However, this method not only increases production costs, but also has a downtime of up to 4 hours, which has a great impact on the production rhythm.

[0004] Therefore, in order to solve the problems of bearing lubrication failure and cage wear in high temperature environment, the industry urgently needs a new lubrication solution. This solution needs to be able to maintain good lubrication performance in high temperature environment, reduce bearing wear, extend bearing service life, and avoid sudden shutdown of production line.

We organized personnel on site to wear insulation clothing and install 30 meters of DN20 water pipes from both sides of the single-roller circulating water pipe to the bearing seats on both sides of the star wheel. At the same time, a self-made spray device above the star wheel bearing seat uses water cooling to cool the bearing seat. The implementation of the above measures effectively reduces the temperature of the bearing seat. Based on the above-mentioned transformation plan, the utility model provides a spray cooling device installed on the bearing seat.

[0008] As a further supplement to the above technical solution, a limit plate is fixed under each of the side baffles, and both ends of the limit plate extend to two arched frames respectively to prevent the sprinkler from sliding down due to its gravity.

[0027] As attached Figures 1 to 4 As shown, a spray cooling device installed on a bearing shoe seat includes a base 1, an arch support 2 is arranged on the base 1, and a sprayer 3 is arranged on the arch support 2. The key component sprayer 3 is composed of a plurality of arch tubes 301, which are arranged side by side and connected in the middle by a shunt pipe 302. The shunt pipe 302 is connected with an interface pipe 303 for externally connecting a circulating water pipeline, and a plurality of spray holes 304 are opened on the inner side of each arch tube 301 along its axial direction. Embodiment 2

[0028] In order to facilitate installation and not affect the spray water cooling effect. Figure 5 As shown, the arch bracket adopts the following modular assembly design: the arch bracket 2 mainly includes two arch frames 201, and side baffles 202 are fixedly connected between the two, and the two side baffles 202 are symmetrically arranged along the center line of the arch frames 201. Hole foot plates 205 are fixed at both ends of each arch frame 201, which are used to install the arch bracket 2 on the base 1 with bolts, and a plurality of built-in slots 203 corresponding to the arch tube 301 are arranged on the inner side of each side baffle 202, and a limiting plate 204 is fixed under each of the side baffles 202, and the two ends of the limiting plate 204 extend to the two arch frames 201 respectively, and the sprinkler 3 is assembled and connected with the arch bracket 2 by embedding the two ends of the plurality of arch tubes 301 in the built-in slots 203 respectively.

[0029] In the above embodiment, the design of the limit plate can effectively prevent the sprayer 3 from sliding down due to its gravity, causing the arch tube 301 to directly contact the outer shell of the star wheel bearing 4, thereby causing the sprayed cooling water to spray out laterally, affecting the on-site environment; at the same time, it can also ensure the water cooling effect. Embodiment 3

[0030] In order to facilitate the smooth implementation of the above-mentioned embodiments 1 and 2, and also to complete the above-mentioned transformation without stopping the machine, that is, without removing the wheel shoe seat bearing 4, the base can be smoothly installed on the frame of the sintering machine. The base is a key component for on-site installation, as shown in the attached Figure 5 As shown, the following design scheme is adopted: wherein the base 1 includes two mounting plates 101, and a horizontal connecting rod 102 is fixedly connected between the two, the horizontal connecting rod 102 is located on one side of the two mounting plates 101, and a movable connecting rod 103 is arranged on the other side thereof, and slot holes 104 are arranged on both sides of each mounting plate 101, respectively, for bolts to pass through the hole foot plate 205 and the slot holes 104 in sequence to fix the arch frame 201 on the mounting plate 101, and at least two mounting holes 105 are arranged on each mounting plate 101, for using bolts to install the base 1 on the frame of the sintering machine.

We organize personnel wearing heat-insulating clothing to first install the base 1 on the frame of the sintering machine with bolts; then, assemble the arch bracket 2 and the sprinkler 3, and fix the arch bracket 2 on the base 1 with bolts. During installation, the slot 104 is used to adjust the installation position so that multiple arch pipes 301 cover the top of the star wheel bearing 4; finally, 30 meters of DN20 water pipes are installed from both sides of the single-roller circulating water pipeline to the bearing seats on both sides of the star wheel for connecting the interface pipe 303, and the on-site transformation is completed.
