Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a bearing assembly and a belt filter. Background Art

[0002] Related technologies point out that one of the most common faults of belt filters during the production process is the damage of the filter cloth roller seat bearing. Once the seat bearing is damaged, the bearing will become stuck, the roller will not rotate, and the filter cloth running resistance will increase. In addition, it may cause the internal cage of the bearing to break, the rollers to scatter, the bearing rotation accuracy to decrease, the height of the rollers on both sides to be inconsistent, causing the filter cloth to deviate, which is easy to cause the filter cloth to scatter, and affect the on-site environment.

[0003] At present, the filter cloth roller bearings of the belt filter are made of ordinary carbon steel bearings, and the bearing seats are made of cast iron. Since the material gypsum slurry and its filtrate are acidic solutions with a pH of 2, when the filter cloth is spilled or the equipment is cleaned manually, the acidic solution and flushing water will directly fall into the filter cloth roller bearing seat. At the same time, the filter cloth needs to be flushed after the material is carried. The accumulated water on the filter cloth will be brought to the filter cloth guide roller and flow to the bearings on both sides as the guide roller rotates. Therefore, the outside of the bearing with a seat is always wet, which is easy to cause corrosion over time. Although there are seals on both sides of the bearing with a seat, the effect is not good. Once the seal fails, water will directly enter the bearing, causing rust to the bearing roller and retainer, and accelerating the damage of the bearing. Utility Model Content

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Reference below Figure 1-Figure 6 A bearing assembly 100 according to an embodiment of a first aspect of the present invention is described.

[0035] like Figure 1 As shown, the bearing assembly 100 according to the embodiment of the first aspect of the utility model includes: a bearing 1 and a sealing assembly 2.

[0036] Specifically, the bearing assembly 100 is arranged on the frame 200 of the belt filter, the bearing 1 includes a bearing seat 11, the bearing seat 11 is arranged on the frame 200, and the sealing assembly 2 includes: a first sealing member 21, the first sealing member 21 forms a receiving space, the first sealing member 21 is arranged at one end of the roller main shaft 301 of the filter, the bearing seat 11 is located in the receiving space, and the first sealing member 21 is detachably connected to the bearing seat 11. Therefore, the structure of the bearing assembly 100 is simple, and the first sealing member 21 can prevent liquid or impurities from entering the interior of the bearing 1, thereby extending the service life of the bearing assembly 100.

[0037] Since the filter cloth roller 300 of the belt filter is basically located below the vacuum filtration area, the daily deviation of the filter cloth causes the material to be spilled or the flushing water of the cleaning equipment will directly fall on the bearing seat 11 of the filter cloth roller 300, and the filter cloth will be flushed during the return journey after the unloading is completed, so that the accumulated water on the filter cloth will be brought to the roller 300. As the roller 300 rotates, the water will flow to both sides and finally reach the bearing 1, which will cause corrosion damage to the bearing seat 11 and the bearing 1 over time. According to the bearing assembly 100 of the embodiment of the utility model, by setting the first seal 21 on the bearing seat 11, the corrosion of the inside of the bearing 1 by the material or flushing water is effectively avoided, the service life of the bearing 1 is extended, the probability of failure of the bearing 1 is reduced, the impact of the failure of the bearing 1 on the operation of the equipment is reduced, and the efficiency of the production operation is guaranteed.

[0038] In some embodiments of the utility model, the first seal 21 is formed with a first clamping portion, the bearing seat 11 is formed with a second clamping portion, and the first seal 21 and the bearing seat 11 are connected by the first clamping portion and the second clamping portion. Therefore, the first clamping portion and the second clamping portion are cleverly designed, which reduces the difficulty of disassembly and assembly between the bearing seat 11 and the first seal 21 and improves the assembly efficiency of the first seal 21.

[0039] In some embodiments of the present invention, Figure 2 As shown, one of the first clamping part and the second clamping part is formed as a clamping groove 212, and the other of the first clamping part and the second clamping part is formed as a clamping block, and the clamping groove 212 is engaged with the clamping block. Therefore, the design of the clamping groove 212 and the clamping block simplifies the connection structure between the first sealing member 21 and the bearing seat 11, reduces the difficulty of disassembling and assembling the bearing seat 11 and the first sealing member 21, and improves the production stability.

[0040] In some embodiments of the present invention, Figure 2As shown, the top wall of the accommodating space is formed with a downwardly extending clamping plate 211, and the clamping plates 211 include two, and the two clamping plates 211 define a clamping groove 212. Thus, the assembly stability of the first seal 21 is improved, and the sealing effect of the first seal 21 is improved, so as to prevent the slurry from being scattered into the bearing 1 and prevent the flushing water from corroding the inside of the bearing 1.

[0041] In some embodiments of the present invention, Figure 1 As shown, a baffle 213 is formed on the side wall of the first seal 21 facing the roller 300, and the baffle 213 extends toward the direction of the roller 300. Specifically, since there is a gap between the second seal 22 and the first seal 21, when the second seal 22 rotates, the liquid above the sealing assembly 2 falls onto the main shaft 301 between the second seal 22 and the first seal 21 and easily flows into the bearing 1. The provision of the baffle 213 achieves a better sealing effect.

[0042] In some embodiments of the present invention, the sealing assembly 2 further includes: a second sealing member 22, which is sleeved on the roller main shaft 301, and the second sealing member 22 is arranged adjacent to the first sealing member 21 and is located at the lower side of the baffle 213. Figure 2 As shown, the second seal 22 is disposed between the first seal 21 and the roller 300 , whereby the second seal 22 further improves the sealing effect and further effectively prevents the accumulated water on the roller 300 from flowing into the bearing 1 .

[0043] In some embodiments of the present invention, the sealing assembly 2 further includes: a sealing ring 23 , which is disposed in the groove 222 to prevent liquid from flowing into the bearing 1 .

[0044] Furthermore, the groove 222 includes at least one groove, and at least one groove 222 is arranged in a one-to-one correspondence with the sealing ring 23. Figure 4 and Figure 6 As shown, the grooves 222 include two, and sealing rings 23 are provided in the two grooves 222, which improve the sealing effect, further avoid the existence of a gap between the second sealing member 2 and the roller main shaft 301, and further avoid the accumulation of water on the roller 300 from flowing into the bearing 1.

[0045] The following will refer to Figure 1-Figure 6 A bearing assembly 100 according to a specific embodiment of the present invention is described.

[0046] Reference Figure 1In order to prevent the bearing 1 of the roller 300 from directly contacting the spilled materials and flushing water, a first seal 21 is firstly arranged outside the bearing seat 11. To facilitate the disassembly and assembly of the first seal 21 during daily maintenance, a slot 212 structure is formed at the top of the first seal 21, which is different from the previous fixing by bolts. During installation, the slot 212 directly clamps the top two sides of the bearing seat 11, eliminating the trouble of disassembling and assembling bolts. In order not to hinder daily inspection work, the first seal 21 is not sealed on the outer side of the frame 200, but is open. The top and the other three sides are all sealed, and only the shaft hole 214 is left on the front side of the inner side of the frame 200.

[0047] In addition, the basic external dimensions of the first seal 21 can be determined by measuring the external dimensions of the base of the bearing seat 11, and the width of the top width of the bearing seat 11 and the distance from the top of the bearing seat 11 to the rotating top of the main shaft 301 can be measured to determine the width of the internal groove 212 of the first seal 21 and the length of the clamping plate 211.

[0048] Furthermore, in order to prevent the accumulated water after washing the filter cloth from flowing toward the bearing seat 11 as the roller 300 rotates, a second seal 22 is installed on the roller main shaft 301 close to the bearing seat 11, which can effectively prevent the accumulated water on the roller 300 from flowing into the bearing 1.

[0049] The belt filter according to the second embodiment of the utility model comprises the bearing assembly 100 according to the first embodiment of the utility model.

[0050] According to the belt filter of the embodiment of the utility model, by setting the bearing assembly 100 of the first embodiment, the production stability of the belt filter is improved, the failure rate of the belt filter is reduced, and the service life of the belt filter is extended.
