Description

Technical Field

[0001] The invention relates to the technical field of cleaning and maintaining the surface of a rock wool centrifugal roller, in particular to an adaptive cleaning device applied to a rock wool production centrifuge. Background Art

[0002] Rock wool is a fireproof and energy-saving thermal insulation material with excellent performance. In the process of rock wool production, the rock needs to be melted at high temperature in a melting furnace, and then the melted raw materials are poured onto the top of the centrifuge. The surface is cooled and fiberized at the same time by the rotation of the centrifugal roller, and then fixed into shape by the subsequent felt board, so that it can be processed well.

[0003] In the process of using traditional rock wool centrifuges, the centrifugal roller will wear out due to long-term contact with the rock after melting at high temperature. If the whole centrifugal roller is replaced, it will not only be costly but also have a long replacement cycle. At the same time, a certain amount of material that cannot be thrown off will stick to the surface of the centrifugal roller. If it is not cleaned in time, it will easily lead to an increasing amount of adhesion, which will greatly affect production. In addition, the temperature of the centrifugal roller cannot be effectively controlled, resulting in low production efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the replacement of traditional centrifugal rollers is not only costly, but also has a long replacement cycle. At the same time, a certain amount of material that cannot be thrown off will stick to the surface of the centrifugal roller. If it cannot be cleaned in time, it is easy to cause the amount of stickiness to increase, greatly affecting production. In addition, the temperature of the centrifugal roller cannot be effectively controlled, resulting in low production efficiency.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an adaptive cleaning device applied to a rock wool production centrifuge, comprising a centrifuge housing and a centrifugal roller shaft installed on the centrifuge housing, wherein a split external heat exchange cover is axially mounted on the outer side surface of the centrifugal roller shaft, an electrically controlled external obstacle removal module is installed on the side wall of the centrifuge housing at the periphery of the split external heat exchange cover, a bottom heat exchange water tank is fixedly installed at the bottom of the outer side of the centrifuge housing, an internal return pipe connected to the return pipe of the bottom heat exchange water tank is fixedly installed inside the centrifuge housing at the periphery of the split external heat exchange cover, and the bottom heat exchange water tank is connected to the inside of the centrifuge roller shaft through a top inlet pipe.

[0006] The side wall of the centrifuge housing is provided with an annular telescopic groove at the installation position of the electric-controlled external obstacle removal module.

[0007] The electrically controlled external obstacle clearing module comprises an embedded telescopic support rod fixed inside an annular telescopic groove, an annular cover shell fixedly mounted on the outer protruding end of the embedded telescopic support rod, an internal scraper plate slidably mounted on the inner side of the annular cover shell, and an electrically controlled internal drive ring for controlling the extension and retraction of the internal scraper plate.

The side adjustment motor meshes with the inner tooth surface of the internal adjustment ring through a gear on the output shaft.

[0009] A plurality of optical detection modules are fixedly mounted on the inner side surface of the annular cover.

[0010] A central flow channel connected to the top inlet pipe is provided at the inner shaft core of the centrifugal roller shaft, and a plurality of peripheral flow guide holes for connecting the split external heat exchange cover and the central flow channel are provided on the outer side of the centrifugal roller shaft.

[0011] A silent water pump is fixedly mounted on the inner bottom surface of the bottom heat exchange water tank, and the top inlet pipe is inserted into the bottom heat exchange water tank and fixedly connected with the outlet pipe of the silent water pump.

[0012] A plurality of internal supporting copper sheets of an integral structure are fixedly mounted on the inner side surface of the split external heat exchange cover.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Figure 1 , Figure 2 , Figure 3 and Figure 4An adaptive cleaning device for a rock wool production centrifuge is shown, comprising a centrifuge housing 1 and a centrifugal roller 2 mounted on the centrifuge housing 1, a split external heat exchange cover 3 is axially mounted on the outer side surface of the centrifugal roller 2, an electrically controlled external obstacle removal module 4 is mounted on the side wall of the centrifuge housing 1 at the periphery of the split external heat exchange cover 3, a bottom heat exchange water tank 5 is fixedly mounted at the bottom outside the centrifuge housing 1, an internal return pipe 6 connected to the return pipe of the bottom heat exchange water tank 5 is fixedly mounted inside the centrifuge housing 1 at the periphery of the split external heat exchange cover 3, and the bottom heat exchange water tank 5 is connected to the inside of the centrifuge roller 2 via a top inlet pipe 7.

[0031] Working principle: Under normal working conditions, the centrifugal roller 2 drives the split external heat exchange cover 3 to rotate, and then the liquid is supplied from the centrifugal roller 2 to the split external heat exchange cover 3 through the bottom heat exchange water tank 5 and the top inlet pipe 7, and then flows horizontally through the split external heat exchange cover 3, and finally flows back to the bottom heat exchange water tank 5 through the internal reflux pipe 6.

[0032] When the split external heat exchange cover 3 needs to be maintained, the centrifugal roller 2 can be slowly rotated, and then the electrically controlled external obstacle removal module 4 can be pushed outward along the split external heat exchange cover 3 to clear the sticky substances on the surface of the split external heat exchange cover 3. At the same time, the wear degree of the surface of the split external heat exchange cover 3 can be detected, which is convenient for timely maintenance and replacement.

[0033] The installation method of the split external heat exchange cover 3 is to directly cover the outer side of the centrifugal roller shaft 2, and then fix and assemble it with the outer side of the centrifugal roller shaft 2 through lateral bolts.

[0034] A lateral guide ring connected to the internal return pipe 6 is fixed on the periphery of the split external heat exchange cover 3 inside the centrifuge housing 1, so that the heat exchange fluid in the split external heat exchange cover 3 can flow back to the internal return pipe 6 through the lateral guide ring.

[0035] In order to facilitate lateral storage, an annular telescopic groove 8 is provided on the side wall of the centrifuge housing 1 at the installation position of the electrically controlled external obstacle removal module 4 .

[0036] In order to cooperate with the telescopic adjustment, the electrically-controlled external obstacle clearance module 4 includes an embedded telescopic support rod 41 fixed inside the annular telescopic groove 8, an annular cover shell 42 fixedly installed on the outer protruding end of the embedded telescopic support rod 41, an internal scraper plate 43 slidably installed on the inner side of the annular cover shell 42, and an electrically-controlled internal drive ring for controlling the extension and retraction of the internal scraper plate 43.

[0037] A built-in guide rail for improving the guiding property of the internal scraper plate 43 is fixed on the inner side surface of the annular cover 42. The internal scraper plate 43 is slidably connected to the inner side surface of the annular cover 42 by being sleeved on the built-in guide rail. The internal scraper plate and the internal scraper plates on the adjacent two sides are staggered in layout, so that the scraping area can be ensured while ensuring the fit with the surface of the split external heat exchange cover 3.

[0038] In order to ensure the effect of electric scraping, the electric controlled internal drive ring includes an internal adjustment ring 44 movably installed in the annular cover 42, a driving connecting rod 45 movably installed between the internal adjustment ring 44 and the internal scraper plate 43, and a side adjustment motor 46 for controlling the internal adjustment ring 44. The side adjustment motor 46 is meshed with the inner tooth surface of the internal adjustment ring 44 through the gear on the output shaft.

[0039] The internal adjustment ring 44 rotates along the inner arc surface of the annular cover 42 , and squeezes the driving connecting rod 45 while rotating, so that the driving connecting rod 45 drives the internal scraper plate 43 to slide and adjust on the inner side surface of the annular cover 42 .

[0040] In order to cooperate with optical detection, two optical detection modules 47 are fixedly mounted on the inner side of the annular cover 42 .

[0041] The optical detection module 47 is used to automatically identify the distance between the annular cover 42 and the split external heat exchange cover 3, thereby controlling the side adjustment motor 46 to drive the internal adjustment ring 44 to rotate, and then the internal scraper plate 43 is controlled by the driving connecting rod 45 to extend toward the position of the split external heat exchange cover 3, and then the sticky matter located on the outside of the split external heat exchange cover 3 is scraped away laterally.

[0042] In order to cooperate with the internal flow diversion, a central flow channel 9 connected to the top inlet pipe 7 is opened at the internal axis position of the centrifugal roller shaft 2, and a plurality of peripheral flow diversion holes 10 for connecting the split external heat exchange cover 3 and the central flow channel 9 are opened on the outer side of the centrifugal roller shaft 2.

[0043] By opening the flow guide hole inside, the central flow channel 9 can be thrown outwards and then guided back to the inside of the internal return pipe 6 of the centrifuge housing 1 through the split external heat exchange cover 3.

[0044] In order to cooperate with driving the heat exchange liquid, a silent water pump 11 is fixedly installed on the bottom surface of the bottom heat exchange water tank 5, and the top inlet pipe 7 is inserted into the bottom heat exchange water tank 5 and fixedly connected with the outlet pipe of the silent water pump 11.

[0045] The heat exchange liquid in the bottom heat exchange water tank 5 is introduced into the top inlet pipe 7 through the silent water pump 11.

[0046] In order to enhance the internal support force and perform independent separation, a plurality of internal support copper sheets 12 of an integral structure are fixedly mounted on the inner side surface of the split external heat exchange cover 3 .

[0047] A plurality of independent chambers are formed between the centrifugal roller shaft 2 and the split external heat exchange cover 3 through the internal supporting copper sheet 12 .

[0048] A strip-shaped installation limit groove matched with the internal supporting copper sheet 12 is provided on the outer arc surface of the centrifugal roller shaft 2 , thereby improving the installation firmness of the centrifugal roller shaft 2 and the split external heat exchange cover 3 .

[0049] In order to cooperate with the electric control, an electric control regulating valve 13 is fixedly installed inside the peripheral flow guide hole 10 .

[0050] In order to cooperate with the temperature monitoring inside different chambers, a temperature sensor 14 for controlling the electric control valve 13 is fixedly mounted on the outer arc surface of the centrifugal roller shaft 2 at one side of the outer guide port of the peripheral guide hole 10.

[0051] When the temperature inside the chamber exceeds the set maximum temperature, the temperature sensor 14 will start the electronically controlled regulating valve 13, control the peripheral flow guide hole 10 to open, and then connect the central flow channel 9 with the interior of the split external heat exchange cover 3. The silent water pump 11 introduces the heat exchange liquid in the bottom heat exchange water tank 5 into the split external heat exchange cover 3 through the centrifugal roller shaft 2, and then introduces it into the internal reflux pipe 6 inside the centrifuge housing 1 through the split external heat exchange cover 3, and then flows back to the bottom heat exchange water tank 5 through the internal reflux pipe 6.

[0052] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
