Description

Technical Field

[0001] The invention relates to a cooling and humidifying roller with a lubricating device, belonging to the technical field of cold slag. Background Art

[0002] The temperature of the slag discharged after the combustion of the power plant boiler is very high (about 1000℃), which is not conducive to transportation and causes heat waste. At present, the hot slag cooling is a traditional method, which is to pour the hot slag into the cooling water pool and use a grab bucket to fish it out after cooling. The efficiency is low and the heat cannot be recovered. It is an outdated process and is basically no longer used. The second is the drum slag cooler, which is currently widely used. It is a slag conveying pipe with multiple spiral blades installed in the drum. The hot slag enters each slag conveying pipe from the slag inlet funnel, connecting pipe, elbow pipe, and cone. As the drum rotates, the hot slag rolls forward in the slag conveying pipe under the guidance of the spiral blades. The cooling water enters the drum from the cooling water jacket and is discharged through the core pipe. In this way, the heat exchange cools the hot slag. The existing slag cooler has the following defects: due to the heavy weight of the drum, there is rolling friction between the roller ring and the roller in the drum, and lubricating oil needs to be added between the roller ring and the roller regularly. At present, the lubricant is added continuously by manpower, which is laborious and time-consuming; and, since the working environment of the drum slag cooler is relatively harsh and there is a lot of dust in the environment, once the drum slag cooler is in operation, the lubrication between the roller ring and the roller is insufficient due to excessive dust and lubricating oil needs to be added. At this time, manual addition of lubricating oil is not only laborious, but also poses a safety risk. Summary of the invention

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figure 1 , 2As shown in Figure 3, the cooling and humidifying drum with a lubricating device comprises a drum 10 and a plurality of rollers 20 for supporting the drum 10, the outer portion of the roller 20 is provided with a lubricating device, the lubricating device comprises an oiling roller 30 and an oil storage device 50, the oiling roller 30 comprises a first roller body 31 tangent to the roller body of the roller 20, and a first roller shaft 32, the first roller body 31 is fixedly connected to the first roller shaft 32; the oil storage device 50 comprises an oil tank 51 filled with lubricating oil 53, the top of the oil tank 51 is provided with a through hole 511 for the lower portion of the first roller body 31 to enter and exit, the lower portion of the first roller body 31 is immersed in the lubricating oil 53 inside the oil tank 51.

[0018] During the rotation of the drum 10, under the action of friction, the roller 20 will rotate, and the rotation of the roller 20 will drive the first roller body 31 to rotate. The lower part of the first roller body 31 passes through the through hole 511 and is immersed in the lubricating oil 53 inside the oil tank 51. The rotating first roller body 31 will continuously transfer the lubricating oil 53 to the roller 20, thereby completing the lubrication between it and the rolling ring in the drum 10. In this process, it is only necessary to regularly add the lubricating oil 53 to the oil tank 51, and the oil tank 51 is far away from the drum 10 and the roller 20, so the safety risk of refueling is significantly reduced; at the same time, the normal operation of the drum 10 is not affected during the refueling process, and the drum 10 does not need to stop operating.

[0019] Since the mass of the lubricating oil 53 attached to the surface of the outer circumference of the first roller body 31 is very small each time it rotates, in some relatively harsh working environments, due to the large dust content, it is difficult to meet the lubrication needs between the roller 20 and the roller ring in the drum 10 by relying solely on the lubricating oil 53 attached to the outer circumference of the first roller body 31; further, an annular baffle 33 is provided on both sides of the first roller body 31, and the baffle 33 is sleeved on the outside of the first roller shaft 32 and the inner ring of the baffle 33 is fixedly connected to the first roller shaft 32, and an annular sponge plate 34 is provided on both sides of the first roller body 31, and the sponge plate 34 is located between the baffle 33 and the side wall of the first roller body 31, that is, the annular sponge plate 34 is provided between the baffle 33 and the side wall of the first roller body 31, and the sponge plate 34 is fixedly connected to the baffle 33. Further, an annular metal mesh 35 is provided on both sides of the first roller body 31, and the metal mesh 35 is located between the sponge plate 34 and the side wall of the first roller body 31. Furthermore, the outer diameter of the sponge plate 34 is greater than the diameter of the first roller body 31 , the outer diameter of the metal mesh 35 is greater than or equal to the outer diameter of the sponge plate 34 , and the outer diameter of the baffle 33 is greater than the outer diameter of the metal mesh 35 .

[0020] When the first roller body 31 rotates, the baffle plate 33 and the sponge plate 34 also rotate, and the sponge plate 34 is immersed in the lubricating oil 53 in the oil tank 51. The sponge plate 34 can absorb a large amount of lubricating oil 53, and the lubricating oil 53 contained in the sponge plate 34 can be transferred to the roller 20. The metal mesh 35 can protect the sponge plate 34 and prevent the side wall of the sponge plate 34 from being worn by the rotating roller 20.

[0021] Furthermore, if Figure 1 , 4 As shown, the lubricating device further includes an oil squeezing roller 60 located above the oil adding roller 30, the oil squeezing roller 60 includes a second roller body 61 circumscribed to the first roller body 31 and a second roller shaft 62, the second roller body 61 is fixedly connected to the second roller shaft 62, and an annular squeezing plate 63 is respectively arranged on both sides of the second roller body 61, the squeezing plate 63 is sleeved on the outside of the second roller shaft 62, and the inner ring of the squeezing plate 63 is fixedly connected to the second roller shaft 62, and the edge of the squeezing plate 63 is pressed against the edge of the sponge plate 34. In the oil squeezing roller 60, the rotation of the first roller body 31 will drive the second roller body 61 to rotate, and the rotation of the second roller body 61 will synchronously drive the squeezing plate 63 to rotate, and the edge of the squeezing plate 63 is pressed against the edge of the sponge plate 34, so that the edge of the squeezing plate 63 is always squeezing the edge of the sponge plate 34, which is conducive to squeezing the lubricating oil 53 at the edge of the sponge plate 34, and is conducive to transferring the lubricating oil 53 to the roller 20.

[0022] Furthermore, the edge of the extrusion plate 63 is provided with a plurality of convex portions 631 with arc-shaped outer side walls, and the convex portions 631 are symmetrically distributed along the outer circumference of the extrusion plate 63. During the rotation of the extrusion plate 63, the convex portions 631 will continuously strike the edge of the sponge plate 34, which is conducive to squeezing out the lubricating oil 53 at the edge of the sponge plate 34 and transferring the lubricating oil 53 to the roller 20.

[0023] Furthermore, an annular sponge sealing strip 52 is embedded in the through hole 511. The presence of the sponge sealing strip 52 can minimize the gap between the lower part of the oiling roller 30 and the through hole 511, thereby effectively reducing the probability of dust falling into the oil tank 51 and ensuring the quality of the lubricating oil 53.

[0024] Furthermore, in order to facilitate adding lubricating oil 53 into the oil tank 51, an oil filling hole is provided on the top of the oil tank 51, and a hole plug 55 is provided at the oil filling hole. The hole plug 55 and the oil filling hole can be connected by threads.

[0025] In the above embodiment, the roller 20 is supported by a roller seat, and the rotational connection between the roller 20 and the roller seat can be completed by installing bearings; the oiling roller 30 is supported by an oiling roller seat, and the rotational connection between the first roller shaft 32 and the oiling roller seat can be completed by installing bearings; the oil squeezing roller 60 is supported by an oil squeezing roller seat, and the rotational connection between the second roller shaft 62 and the oil squeezing roller seat can be completed by installing bearings. In the present invention, the rotational connection between the roller 20 and the roller seat, the rotational connection between the first roller shaft 32 and the oiling roller seat, and the rotational connection between the second roller shaft 62 and the oil squeezing roller seat are all existing designs and are not the focus of protection of the present invention.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
