Description

Technical Field

[0001] The invention relates to the technical field of cleaning the sticky material on a belt, in particular to a device for cleaning the sticky material on a belt conveyor. Background Art

[0002] The metal pin hinged crawler track has a simple structure, consisting of a metal pin and a track shoe. The metal pin directly rubs against the pin hole of the track shoe. This type of crawler track wears quickly and has a relatively short life. The belt conveyor is a machine that uses a belt as a traction and load-bearing mechanism to transport materials. It is one of the common continuous motion transportation equipment in coal, metallurgy and other factories and mines. The side of the belt that contacts the material during the material conveying process is the "dirty side", and the side that does not contact the material is the clean side.

[0003] A patent with announcement number CN 106395307 B discloses a belt conveyor cleaning device, which relates to the field of belt conveyors and provides a belt conveyor cleaning device capable of cleaning materials adhered to a tensioning roller. The belt conveyor cleaning device comprises a roller, a first cleaning structure and a second cleaning structure; the first cleaning structure comprises a first cleaning plate, the side of the first cleaning plate close to the roller is inclined upward and the side is close to the roller, the first cleaning plate can scrape off the materials on the roller, the first cleaning plate is pressed down by a spring, and the first cleaning plate can rebound when the materials are firmly adhered; the second cleaning structure is located below the first cleaning structure, and the second cleaning structure comprises a second cleaning plate; in the length direction, the second cleaning plate is high in the middle and low on both sides, one side of the second cleaning plate is close to the roller, and the second cleaning plate can scrape off the materials firmly adhered to the roller. The present invention can be applied to the design and modification of belt conveyors.

[0004] When the belt is running with sticky materials, the materials will adhere to the surface of the track, and the staged track will cause the sticky materials to continue to fall when it is near the redirection roller and the tensioning roller, which will cause more and more materials to accumulate, causing direct friction between the roller and the track. In order to increase the conveying performance, the traditional track will be stretched tight, especially the metal pin hinge track. After being stretched, the gaps between the tracks will be stretched to the maximum, so that when the sticky materials pass through these gaps, the sticky materials will directly block these gaps. The traditional brush cleaning device can only clean the sticky materials on the track surface. The sticky impurities inside the gap cannot be effectively cleaned. The only way is to use the arc surface on the roller surface to bend the track when the track slides on the roller surface, and change the shape of the track to squeeze out the excess sticky impurities inside the track gap. However, this method will cause extrusion friction between the sticky impurities and the roller surface, and the sticky impurities inside the track gap cannot be effectively and thoroughly cleaned out. The friction between the track, sticky substances and rollers will reduce the service life of the roller, which will cause a fire, and will also increase the workload of sanitation and cleaning at the production site and increase labor intensity. Summary of the invention

[0005] To this end, the technical problem to be solved by the present invention is to overcome the problem in the prior art that the traditional crawlers are stretched tight to increase the conveying performance, especially the metal pin hinged crawlers. After being stretched tight, the gaps between the crawlers will be stretched to the maximum, so that when the sticky substances pass through these gaps, the sticky substances will directly block these gaps. The traditional brush cleaning device can only clean the sticky substances on the surface of the crawlers, but cannot effectively clean the sticky impurities inside the gaps. It is impossible to effectively and thoroughly clean out the sticky impurities inside the crawler gaps, and the friction between the crawlers, sticky substances and rollers will reduce the service life of the rollers.

[0006] In order to solve the above technical problems, the present invention provides a belt conveyor sticky material cleaning device, comprising a support frame one and a conveying crawler movably sleeved on the outer surface of the support frame one, a water collecting tank arranged between two groups of support frames one and located at the middle position of the bottom of the conveying crawler, a support frame two located on the outer surface of the water collecting tank and movably overlapped on the outer surface of the conveying crawler, a support rod is fixedly connected to one end of the support frame two, a positioning rod is movably adjusted by threading on the outer surface of the support rod, a motor two is fixedly installed on one end of the support rod, a main roller and an auxiliary roller movably adjusted on the upper and lower side surfaces of the conveying crawler are arranged on the top surfaces of the motor two and the support rod, and a gap is arranged between the two groups of the main roller and the auxiliary roller.

[0008] In one embodiment of the present invention, a water pipe is fixedly connected to the output end of the water pump, and a V-shaped water spray plate movably sleeved on the inner wall of the conveying crawler is fixedly connected to the other end of the water pipe.

[0009] In one embodiment of the present invention, a V-shaped differentiation plate is fixedly connected to the inner wall surface of the ash collecting and filtering box, and guide grooves are arranged on the edge positions of both sides of the bottom of the ash collecting and filtering box.

[0010] In one embodiment of the present invention, a filter screen is fixedly connected to the bottom inner wall of the ash collecting filter box, and the filter screen is positioned on the bottom surface of the V-shaped differentiation plate, while the two side surfaces of the filter screen are positioned on the outer surface of the guide groove.

[0011] In one embodiment of the present invention, a raising strip is fixedly connected to the outer surface of the main roller and the auxiliary roller, an elastic soft strip tube is arranged on the outer surface of the raising strip, and a docking limit groove is arranged between the two raising strips.

[0012] In one embodiment of the present invention, a transmission roller movably connected to the inner wall of the conveyor belt is arranged on the top surface of the support frame, a transmission belt is movably connected to the outer surface of the transmission roller and located at the edge of one side of the conveyor belt, and a motor 1 arranged at the edge of one side of the transmission roller is movably connected to the inner wall of the transmission belt.

[0013] In one embodiment of the present invention, a connecting rod is fixedly connected to the outer surface of the support rod, one end of the connecting rod is fixedly connected to a limiting column located between the conveying tracks, and one end of the limiting column is fixedly connected to an elastic wire.

[0015] In one embodiment of the present invention, a limiting plate movably fitted on the outer surface of the conveying crawler is fixedly connected to the output end of the second motor, and the outer surface of the limiting plate is fixedly mounted on both ends of the main roller.

[0016] The above technical solution of the present invention has the following advantages compared with the prior art:

[0017] The device for cleaning sticky materials of a belt conveyor described in the present invention winds the conveying crawler on the surfaces of the main roller and the auxiliary roller, and utilizes the gap between the two sets of main rollers to make a certain section between the surfaces of the conveying crawler vertically inside the gap between the two sets of main rollers, and at the same time cooperates with the positioning rods on the outer surfaces of the support rods to limit the positions of the support rods on the surfaces of both ends of the main rollers, so that a certain section between the conveying crawler in a vertical state will not change the tightness between the surface of the conveying crawler and the two driving rollers, so that the remaining parts of the conveying crawler are still in a tight state, and the metal pin hinges between the conveying crawler sections in a vertical state inside the gap are in a completely relaxed state, and the relaxed chain will swing to squeeze and discharge the sticky material inside the gap, which greatly facilitates the sticky material inside the gap of the metal pin hinge to be effectively and quickly discharged under external cleaning and self-pushing;

[0018] The device for cleaning sticky materials of a belt conveyor of the present invention cooperates with motor 1 and motor 2 to simultaneously and uniformly drive the driving roller and the main roller. When the conveying crawler is clamped by the main roller and the auxiliary roller, it is bent and moved to the inside of the empty slot gap. At the same time, the auxiliary roller and the main roller are squeezed against each other. The padding strip and the elastic soft strip cylinder on the outer surface are extended into the inside of the docking limit groove. The narrow surface of the elastic soft strip cylinder is deformed and then passes through the cavity inside the metal pin hinge. The elastic soft strip cylinder is squeezed to squeeze out the sticky impurities inside the metal pin hinge cavity, thereby cleaning out a part of the sticky material or loosening a part of the sticky material.

[0019] The present invention relates to a device for cleaning sticky materials on a belt conveyor. When the drooping and swinging conveying crawler surface moves inside the gap between the ash collecting filter box and the V-shaped water spray plate, the water source inside the support frame is pumped into the inside of the water guide pipe in cooperation with the water pump, and then the water source is pumped and discharged through the V-shaped water spray plate on one end of the water guide pipe. The water source is quickly impacted and discharged by the V-shaped water spray plate, and the conveying crawler surface in a vertical and relaxed state is blown and washed, so that the washed sticky materials fall into the ash collecting filter box. At the same time, the V-shaped differentiation plate on the inner wall of the ash collecting filter box is cooperated to push the sticky materials mixed with the water source to both sides for drainage. At the same time, under the guidance of the guide groove, the filter screen plate is cooperated to filter the sticky materials inside the water source. Moreover, under the drainage of the guide groove, the connection between the filter screen plate and the guide groove will push the sticky materials accumulated on the surface of the filter screen plate due to the push of the water source, thereby reducing the clogging effect.

[0032] The conveyor belt 12 is wound around the surfaces of the main roller 144 and the auxiliary roller 145, and the gap between the two groups of main rollers 144 is used to make a certain section between the surfaces of the conveyor belt 12 vertically inside the gap between the two groups of main rollers 144. At the same time, the positioning rods 1411 on the outer surfaces of the support rods 141 are used to limit the positions of the support rods 141 on the surfaces of both ends of the main rollers 144, so that a certain section between the conveyor belt 12 is in a vertical state, and the tightness between the surface of the conveyor belt 12 and the two driving rollers 111 is still changed, so that the rest of the conveyor belt 12 is still in a tight state, and the metal pin hinges between the sections of the conveyor belt 12 in the vertical state inside the gap are in a completely relaxed state. The relaxed chain will swing and squeeze out the viscous material inside the gap, which greatly facilitates the viscous material inside the gap of the metal pin hinge to be effectively and quickly discharged under external cleaning and self-pushing.

[0033] Furthermore, if Figure 1 and Figure 8 As shown, a heightening strip a1 is fixedly connected to the outer surface of the main roller 144 and the auxiliary roller 145, an elastic soft strip a2 is arranged on the outer surface of the heightening strip a1, a docking limit groove a3 is arranged between the two heightening strips a1, a transmission roller 111 movably sleeved on the inner wall of the conveying crawler 12 is arranged on the top surface of the support frame 11, a transmission crawler 112 is movably sleeved on the outer surface of the transmission roller 111 and located on the edge of one side of the conveying crawler 12, a motor 113 arranged on the edge of one side of the transmission roller 111 is movably sleeved on the inner wall of the transmission crawler 112, and a support rod 141 is fixedly connected to the outer surface of the support rod 141. A connecting rod 146 is connected, one end of the connecting rod 146 is fixedly connected to a limiting column 147 located between the conveying crawler 12, one end of the limiting column 147 is fixedly connected to an elastic wire 148, the other end of the elastic wire 148 is fixedly connected to a sleeve 149 movably sleeved on the outer surface of the limiting column 147, one end of the sleeve 149 is fixedly connected to an arc scraper 1410 movably fitted on the outer surface of the driving roller 111, and the output end of the motor 2 142 is fixedly connected to a limiting plate 143 movably fitted on the outer surface of the conveying crawler 12, and the outer surface of the limiting plate 143 is fixedly mounted on both ends of the main roller 144.

[0034] The motor 113 and the motor 2 142 are used to drive the driving roller 111 and the main roller 144 simultaneously and at a uniform speed. When the conveying track 12 is clamped by the main roller 144 and the auxiliary roller 145, it is bent and moved into the empty slot. At the same time, the auxiliary roller 145 and the main roller 144 are squeezed against each other. The pad a1 and the elastic soft strip tube a2 on the outer surface are extended into the docking limit groove a3. The narrow surface of the elastic soft strip tube a2 will be deformed and then pass through the cavity inside the metal pin hinge. The elastic soft strip tube a2 is used to squeeze out the sticky impurities in the metal pin hinge cavity, thereby cleaning out some of the sticky substances or loosening some of the sticky substances.

[0035] Furthermore, if Figure 1 - Figure 3 and Figure 6 - Figure 7 As shown, a dust collecting and filtering box 131 arranged on the bottom surface of the conveying crawler 12 is fixedly connected to the top surface of the water collecting box 13, a water pump 135 is fixedly installed on the top surface of the water collecting box 13 and on the edge positions on both sides of the dust collecting and filtering box 131, a water guide pipe 136 is fixedly connected to the output end of the water pump 135, and a V-shaped water spray plate 137 movably sleeved on the inner wall of the conveying crawler 12 is fixedly connected to the other end of the water guide pipe 136, a V-shaped differentiation plate 134 is fixedly connected to the inner wall of the dust collecting and filtering box 131, guide grooves 132 are arranged on the edge positions on both sides of the bottom of the dust collecting and filtering box 131, a filter screen plate 133 is fixedly connected to the inner wall of the bottom of the dust collecting and filtering box 131, and the position of the filter screen plate 133 is arranged on the bottom surface of the V-shaped differentiation plate 134, and the two side surfaces of the filter screen plate 133 are arranged on the outer surface of the guide groove 132.

[0036] When the surface of the drooping conveyor crawler 12 moves in the gap between the ash collecting filter box 131 and the V-shaped water spray plate 137, the water source inside the support frame 11 is pumped into the inside of the water pipe 136 in cooperation with the water pump 135, and then the water source is pumped and discharged out through the V-shaped water spray plate 137 on one end of the water pipe 136. The water source is quickly impacted and discharged by the V-shaped water spray plate 137, and the surface of the conveyor crawler 12 in a vertical and relaxed state is blown and washed, so that the washed viscous substances fall into the inside of the ash collecting filter box 131, and at the same time, the ash collecting filter box 131 is cooperated with. The V-shaped differentiation plate 134 on the inner wall surface guides and pushes the viscous substance mixed with the water source to both sides, and at the same time, under the guidance of the guide groove 132, the filter screen plate 133 cooperates to filter out the viscous substance inside the water source. Moreover, under the drainage of the guide groove 132, the connection between the filter screen plate 133 and the guide groove 132 will push away the viscous substance accumulated on the surface of the filter screen plate 133 due to the push of the water source, thereby reducing the clogging effect and preventing the water source mixed with the viscous substance from accumulating on the surface of the filter screen plate 133 and causing clogging on the surface of the filter screen plate 133.

[0037] Working principle: The conveyor belt 12 is wound on the surface of the main roller 144 and the auxiliary roller 145, and the gap between the two sets of main rollers 144 is used to make a certain section between the surface of the conveyor belt 12 vertically inside the gap between the two sets of main rollers 144, and at the same time, the positioning rods 1411 on the outer surface of the support rods 141 are used to limit the position of the support rods 141 on the surfaces of both ends of the main rollers 144, so that a certain section between the conveyor belt 12 is in a vertical state, and the tension between the surface of the conveyor belt 12 and the two driving rollers 111 is still changed, so that the rest of the conveyor belt 12 is still in a tight state, and the sections of the conveyor belt 12 in the vertical state inside the gap are The metal pin hinge is in a completely relaxed state, and the relaxed chain will swing to squeeze and discharge the sticky material inside the gap, which greatly facilitates the effective and rapid discharge of the sticky material inside the metal pin hinge gap under external cleaning and self-pushing; the motor 113 and the motor 2 142 are used to simultaneously and uniformly drive the drive roller 111 and the main roller 144. When the conveyor track 12 is clamped by the main roller 144 and the auxiliary roller 145, it is bent and moved to the empty slot. At the same time, the auxiliary roller 145 and the main roller 144 are squeezed against each other, and the pad strip a1 and the elastic soft strip roller a2 on the outer surface are used to extend into the docking limit groove a3. The narrow surface of the elastic soft strip a2 will be deformed and then pass through the cavity inside the metal pin hinge, and the viscous impurities inside the metal pin hinge cavity will be squeezed out by the extrusion of the elastic soft strip a2, thereby cleaning out a part of the viscous material or loosening a part of the viscous material; when the surface of the drooping and swinging conveyor crawler 12 moves in the gap between the ash collecting filter box 131 and the V-shaped water spraying plate 137, the water source inside the support frame 11 is injected into the inside of the water pipe 136 in conjunction with the water pump 135, and then the water source is injected and discharged through the V-shaped water spraying plate 137 at one end of the water pipe 136, and the water source is quickly impacted and discharged by the V-shaped water spraying plate 137, which is vertical and relaxed. The surface of the conveyor crawler 12 in the state is blown and washed, so that the washed viscous material falls into the inside of the ash collection filter box 131, and at the same time, the V-shaped differentiation plate 134 on the inner wall of the ash collection filter box 131 is used to push the viscous material mixed with the water source to both sides for drainage. At the same time, under the guidance of the guide groove 132, the filter screen plate 133 is used to filter the viscous material inside the water source. Moreover, under the drainage of the guide groove 132, the connection between the filter screen plate 133 and the guide groove 132 will be pushed away by the water source, reducing the clogging effect. At the same time, the spraying of the water source can effectively prevent the crawler from dusting and dust in the space.As the conveyor belt 12 is continuously driven and moved on the surface of the driving roller 111, the arc scraper 1410 on one end of the matching sleeve 149 is attached to the outer surface of the driving roller 111. The arc scraper 1410 is used to clean and scrape off the sticky impurities adhering to the surface of the driving roller 111 while the driving roller 111 is continuously rotating. When some impurities with excessive rolling adhesion are encountered, the arc scraper 1410 will be pushed, so that the arc scraper 1410 can change the spacing when encountering some impurities that cannot be scraped off at one time.

[0038] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
