Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It will be apparent that the described embodiments are one embodiment, but not all embodiments, of the present invention. All other embodiments, which can be made by a person skilled in the art without creative efforts, based on the described embodiments of the present invention fall within the protection scope of the present invention.
It is to be noted that unless otherwise defined, technical or scientific terms used herein should be taken in a general sense as understood by one of ordinary skill in the art to which the present invention belongs.
In the description of the embodiments of the present invention, the meaning of "plurality" is at least two, for example, two, three, etc., unless explicitly defined otherwise.
The embodiment of the invention provides movable equipment for cleaning radioactive waste liquid sediment.
Referring to fig. 1 and 2, a removable device according to an embodiment of the present invention includes: the device comprises a chassis main body, two groups of travelling devices, a stirring device and a suction device.
The chassis main body includes a bottom plate 13 and two side plates 14 respectively provided on both sides of the bottom plate 13 in the width direction of the bottom plate 13. It will be readily understood that the width direction of the base plate 13 is the horizontal direction perpendicular to the walking direction of the movable apparatus.
The two sets of running gear are symmetrically arranged on the two side plates 14 and configured to be able to run in the radioactive waste sediment.
Each group of walking devices comprises: at least one drive wheel 16, a plurality of load bearing wheels 17, and the track 10. The drive wheel 16 is provided to the side plate 14. A plurality of load-bearing wheels 17 are respectively provided at the lower portions of the side plates 14. The track 10 is sleeved outside at least one drive wheel 16 and a plurality of load bearing wheels 17. The driving device 19 is disposed on the base 13, and is used for driving the driving wheels 16 of the two sets of running devices to rotate. The side plate 14 is in an inverted trapezoid shape as a whole, the bearing wheels 17 are arranged at the lower part of the side plate 14, and the driving wheels 16 are arranged at the front end and the rear end of the side plate 14. Each set of running gear may also include a plurality of tensioning wheels 18 disposed on the upper portion of the side plates 14 for tensioning the track 10.
The stirring device is configured to stir the radioactive waste deposit to form a suspension. The suction device is configured to suck the suspension. The suction means comprise a suction opening 32 provided in the base plate 13.
The agitation apparatus includes two agitation wheels 22 provided below the bottom plate 13 in the width direction of the bottom plate 13, and the suction port 32 is located on one side of the two agitation wheels 22 in the length direction of the bottom plate 13. It will be readily appreciated that the length direction of the base 13 coincides with the walking direction of the mobile device.
As indicated by the arrow in fig. 2, the two stirring wheels 22 are arranged to rotate relative to each other to drive the suspension to flow through the gap between the two stirring wheels 22 to the side of the suction opening 32.
In the related art, only one stirring wheel 22 is usually disposed on the bottom plate 13, and when the stirring wheel 22 rotates, the water flow is driven to form hydraulic stirring, so as to stir the radioactive sediment (i.e. radioactive waste sediment) to form suspension (i.e. slurry). Under the hydraulic agitation of the agitation wheel 22, the slurry flows radially around, resulting in a lower liquid level flowing to the suction port 32 located near the agitation wheel 22, and the total amount of slurry sucked by the suction port 32 decreases, resulting in slow suction. In particular, the two stirring wheels 22 are arranged on the bottom plate 13 along the width direction of the bottom plate 13, and when the two stirring wheels 22 rotate relatively, more slurry is driven to flow along the gap between the two stirring wheels 22 towards the suction opening 32 positioned at one side of the two stirring wheels 22, so that the total amount of slurry near the suction opening 32 is greatly increased, and the suction effect is improved.
In some embodiments, the blades 221 of the two agitator wheels 22 are counter-rotating, so that when the two agitator wheels 22 are rotated relative (or toward each other), a large amount of slurry can be collected toward the suction port 32 side. The vane 221 may be rotated in the same direction as the rotation direction of the pulsator 22.
The stirring device further comprises two stirring motors 21 for driving one stirring wheel 22 to rotate respectively. The stirring motor 21 may be disposed above the bottom plate 13.
The suction device may further comprise a suction pump 31, the suction pump 31 being connected to the suction opening 32 by a pipe for providing suction. The suction pump 31 may be disposed above the bottom plate 13. The suction pump 31 may be, for example, a diaphragm pump.
Referring to fig. 3 and 4, the stirring device further includes a protecting cover 23 disposed below the bottom plate 13, the protecting cover 23 is covered on the outer sides of the two stirring wheels 22, and the protecting cover 23 is provided with a plurality of openings 230 for allowing slurry to pass through. The protection cover 23 can protect the blades 221 of the agitator wheel 22 and prevent the blades 221 from being worn.
The side of the protective cover 23 facing the suction port 32 is provided with a liquid outlet 231. When the two stirring wheels 22 rotate relatively, more slurry is driven to flow along the gap between the two stirring wheels 22 towards the suction opening 32 at one side of the two stirring wheels 22, and the existence of the liquid outlet 231 enables the protection cover 23 to protect the blades 221 and not prevent the slurry from flowing towards one side of the suction opening 32.
The protection cover 23 may include a cover plate having a rectangular shape and a connection plate extending from the periphery of the cover plate toward the bottom plate 13, and the liquid outlet 231 is formed in the connection plate on a side facing the suction port 32. The openings 230 are evenly distributed over the cover plate and the connecting plate.
Referring to fig. 3 and 5, the suction device further includes: a filter cover 34 disposed below the bottom plate 13, the filter cover 34 being disposed outside the suction port 32, and a plurality of filter holes 3410 being provided in the filter cover 34 for allowing the slurry to pass therethrough. The filter housing 34 can filter out larger particulate matter, prevent the large particulate matter from adversely affecting the suction pump 31, or from clogging the piping. The filter holes 3410 in the filter housing 34 may be the same shape and size as the openings 230 in the protective cover 23.
The side of the filter housing 34 facing the two agitator wheels 22 forms a collection trough 340 with openings for collecting slurry from the gap between the two agitator wheels 22. Due to the presence of the collection trough 340, the filter housing 34 not only functions as a filter, but also as a collector for the slurry to collect a large amount of slurry within the filter housing 34, thereby facilitating an increase in the suction efficiency of the suction port 32.
Referring to fig. 5 and 6, the filter housing 34 includes a cover plate 341 and a connection plate 342 extending from a peripheral edge of the cover plate 341 toward the bottom plate 13, the connection plate 342 connecting the cover plate 341 with the bottom plate 13. The top end of the connection plate 342 (i.e., the end facing the bottom plate 13) forms a flange, and is connected to the bottom plate 13 by a fastener.
The cover 341, the connecting plate 342 and the base 13 together form a filter chamber. Suction port 32 is located inside the filter cavity.
The cover plate 341 is recessed inwardly (i.e., toward the bottom plate 13) to form a collecting tank 340, the collecting tank 340 communicates with the filter chamber through a filter hole 3410, and the collecting tank 340 forms the aforementioned opening toward the side of the two stirring wheels 22 for collecting slurry from the gap between the two stirring wheels 22.
In some embodiments, the bottom wall of the collection trough 340 includes a first bottom wall 3411 and a second bottom wall 3412, wherein the first bottom wall 3411 is parallel to the bottom plate 13 and the second bottom wall 3412 extends obliquely upward from the first bottom wall 3411 toward one side of the two agitator wheels 22 to be flush with the top end of the connecting plate 342. Wherein the side of the second bottom wall 3412 remote from the first bottom wall 3411 forms an opening of the collecting channel 340 towards the two stirring wheels 22. Because the second bottom wall 3412 extends obliquely upwards, when the slurry flows towards the collecting tank 340, the slurry can gradually enter the filter cavity through the filter holes 3410 in the flowing process, so that the resistance of the slurry to continue flowing is reduced, and the slurry is prevented from flowing back as much as possible.
In some embodiments, the filter apertures 3410 of the filter housing 34 are provided only on the bottom wall of the collection trough 340 and the cover plate 341 around the collection trough 340. That is, the connecting plate 342 of the filter housing 34 and the side wall of the collecting tank 340 are both closed, and no filter holes 3410 are provided. Slurry from one side of the agitator wheel 22 does not flow outwardly through the web 342 of the filter housing 34 and the side walls of the collection tank 340 after entering the interior of the filter chamber through the collection tank 340, thereby further ensuring that slurry entering the filter chamber can be pumped.
In some embodiments, the perimeter of first bottom wall 3411 includes a first straight line segment that meets second bottom wall 3412 and an outwardly projecting arcuate line segment that meets both ends of the first straight line segment. The design of the arc section can gently block the flow of the slurry, and avoid causing the turbulent flow of the slurry.
In some embodiments, second bottom wall 3412 includes a rectangular surface 34121 that meets first bottom wall 3411 and a trapezoidal extension surface 34122 that meets rectangular surface 34121 such that the channel width of collection channel 340 tapers inwardly from the opening to create a slurry collecting effect.
The width of the opening of the collecting tank 340 may be larger than the width of the liquid outlet 231 of the protection cover 23, so that the slurry flowing out of the liquid outlet 231 enters the collecting tank 340 as much as possible.
Referring to fig. 2 and 3, the suction device further includes: and a spray part 33 provided in the filter cover 34 for spraying and decontaminating the filter cover 34. The spray holes are uniformly distributed in the circumferential direction of the spray part 33, so that the filter cover 34 can be sprayed comprehensively. Since the collecting tank 340 is formed to be recessed in the cover plate 341, the shower portion 33 can directly flush the tank bottom wall of the collecting tank 340. In some embodiments, the mobile device is provided with a high pressure water pipe in communication with the spray portion 33 for providing high pressure water to the spray portion 33.
Referring to fig. 7-11, in some embodiments, the agitation wheel 22 may include: an inner ring body 222, an inner shroud plate 223, an outer ring body 225, an outer shroud plate 224, and a plurality of blades 221 extending in a spiral shape.
The inner ring body 222 has opposite first and second ends 2224, 2225. The inner shroud 223 is connected to the inner ring body 222. The inner shroud 223 extends from a circumferential surface near the first end 2224 of the inner ring body 222 toward the second end 2225 of the inner ring body 222, and is farther from the inner ring body 222 in the radial direction.
The outer ring body 225 is arranged coaxially with the inner ring body 222. The first end 2224 of the inner ring body 222 extends into the interior of the outer ring body 225, and the second end 2225 of the inner ring body 222 extends outwardly from the outer ring body 225. The outer shroud 224 is coupled to an end of the outer ring body 225 proximate the second end 2225 of the inner ring body 222. The outer shroud 224 extends from the outer ring body 225 toward the second end 2225 of the inner ring body 222 and is farther radially from the inner ring body 222.
In the present embodiment, the blades 221 are helical throughout their length. Each of the blades 221 includes a first side edge 2211 in the width direction and a second side edge 2212 opposite to the first side edge 2211, the first side edge 2211 being joined to the outer ring body 225 and the outer shroud 224, and the second side edge 2212 being joined to the inner ring body 222 and the inner shroud 223. Wherein the first side edge 2211 extends from the outer ring body 225 to the outer periphery of the outer shroud 224 along the surface of the outer ring body 225 and the surface of the outer shroud 224, the second side edge 2212 extends from the inner ring body 222 to the outer periphery of the inner shroud 223 along the surface of the inner ring body 222 and the surface of the inner shroud 223, and the adjacent two blades 221, the outer ring body 225, the inner ring body 222, the inner shroud 223 and the outer shroud 224 together define a flow passage for the liquid to flow.
In this embodiment, by abutting the first side edges 2211 of the blades 221 with the outer ring body 225 and the outer side cover plate 224, the second side edges 2212 with the inner ring body 222 and the inner side cover plate 223, and extending the first side edges 2211 from the outer ring body 225 to the outer periphery of the outer side cover plate 224 along the surfaces of the outer ring body 225 and the outer side cover plate 224, the second side edges 2212 from the inner ring body 222 to the outer periphery of the inner side cover plate 223 along the surfaces of the inner ring body 222 and the inner side cover plate 223, the adjacent two blades 221, the outer ring body 225, the inner ring body 222, the inner side cover plate 223, and the outer side cover plate 224 together define a flow passage for the flow of liquid, such that the adjacent two blades 221, the inner ring body 222, and the outer ring body 225 together define a side port (i.e., a flow passage inlet 226) communicating with the flow passage; the adjacent two vanes 221, inner shroud plate 223 and outer shroud plate 224 together define another side port (i.e., flow channel outlet 227) that communicates with the flow channel. Thus, when the stirring wheel 22 rotates at a high speed, the liquid can be driven to enter each flow channel through the flow channel inlet 226 of each flow channel through the port of the outer ring body 225 (i.e., the axial port of the outer ring body 225 on the side away from the inner ring body 222), and flow out at a high speed through the flow channel outlet 227 of each flow channel. Because the whole flow channel is spiral, the liquid can play the role of hydraulic impact stirring when flowing out from the outlet 227 of each flow channel at a high speed.
In the related art, the blades 221 are generally not connected with the inner ring body 222 and/or the outer ring body 225, but are connected with only the inner shroud plate 223 and the outer shroud plate 224. In the embodiment of the application, the connection relation of the blades 221 on the side of the flow channel inlet 226 is changed, the shape of the side of the flow channel inlet 226 is changed, and the flow velocity of liquid at the position of the flow channel inlet 226 can be improved, so that the stirring effect of the stirring wheel 22 is improved as a whole.
In some embodiments, the outer shroud 224 is an annular chamfer. The inventors of the present application have found that the annular chamfer is more advantageous in increasing the flow rate of the liquid in the flow channel than the annular curved surface, so that when the liquid flows out of the flow channel outlet 227, it can fly out at a greater linear velocity, thereby improving the hydraulic agitation effect.
In some embodiments, the inner ring body 222 includes a curved surface section 2221 and a straight tube section 2222 connected to the curved surface section 2221, wherein the curved surface section 2221 extends from the first end 2224 of the inner ring body 222 toward the second end 2225 and is further away from the axis X of the inner ring body 222 in the radial direction, and the generatrix of the curved surface section 2221 is a curve concave toward the axis X of the inner ring body 222. The inner shroud plate 223 is smoothly joined to an end of the curved surface section 2221 remote from the first end 2224, and the second side edge 2212 of the blade 221 extends from the curved surface section 2221 to the outer periphery of the inner shroud plate 223 along the surface of the curved surface section 2221 and the surface of the inner shroud plate 223. The second side edge 2212 of the blade 221 extends from the curved surface section 2221 to the outer periphery of the inner cover plate 223 along the surface of the curved surface section 2221 and the surface of the inner cover plate 223 by smoothly connecting the inner cover plate 223 with the end of the curved surface section 2221 far away from the first end 2224, and the shape of the side of the flow channel inlet 226 is improved, so that the flow velocity of liquid at the flow channel inlet 226 can be further improved, and the stirring effect of the stirring wheel 22 is improved as a whole.
In some embodiments, the inner shroud 223 is a curved structure, and the generatrix of the curved structure is a curve that is convex toward the axis X of the inner ring body 222. According to the embodiment of the application, the bus of the curved surface structure is arranged to be the curve protruding outwards towards the axis X of the inner ring body 222, so that the flow resistance of the flow channel can be reduced, and the flow velocity of liquid in the flow channel can be improved.
In some embodiments, the inner ring body 222 has an axially extending mating portion 2223 configured to mate with a drive shaft. The fitting portion 2223 may be a groove formed on the inner wall of the inner ring body 222. The inner ring body 222 has a shaft hole 2220, and a groove is formed on the shaft hole 2220.
In some embodiments, the first side edge 2211 extends from a middle of the outer race body 225 to an outer periphery of the outer shroud 224. The embodiments of the present application further improve the shape of the side of the flow channel inlet 226, which is advantageous for increasing the flow rate of the liquid at the flow channel inlet 226.
In some embodiments, the diameter of the outer periphery of the inner shroud 223 is the same as the diameter of the outer periphery of the outer shroud 224 and is coaxial with the inner ring body 222 such that each flow channel outlet 227 is located substantially on a torus coaxial with the inner ring body 222.
In some embodiments, the mobile device further comprises a robotic arm 40 disposed on the front side of the chassis body. Suction ports 32 are provided on the rear sides of the two agitation wheels 22. It will be readily appreciated that for a mobile device having a robotic arm 40, the side on which the robotic arm 40 is typically located is the front of the mobile device. By providing the suction ports 32 on the rear sides of the two agitation wheels 22, it is possible to achieve agitation of the agitation wheels 22 on the front side and suction of the suction ports 32 on the rear side during normal running of the movable apparatus.
