[0052] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0053] like Figure 1-4 As shown, according to the embodiment of the present application, a roller chain supported annular cooler is proposed, comprising: an annular cooler body 100, wherein the annular cooler body 100 has a container for carrying high temperature materials, and the annular cooler body 100 carries the container of the high temperature materials for annular motion, thereby realizing material cooling; a roller chain supporting assembly 200, wherein the roller chain supporting assembly 200 is arranged on the annular cooler body 100, and the roller chain supporting assembly is used to carry the container of the high temperature materials of the annular cooler body 100 for annular motion; the roller chain supporting assembly comprises a roller chain supporting frame 210, a roller plate 220 and a closed loop roller chain 230; the roller chain supporting assembly The support frame 210 is composed of a base plate and two vertical plates, the base plate is connected to the annular cooler body 100, two long holes are set in the middle of the vertical plate, the two long holes are used to connect the two ends of the rolling plate 220, the closed circulation roller chain 230 can roll around the rolling plate 220, the closed circulation roller chain 230 at the upper end of the rolling plate 220, its lower side is close to the upper side of the rolling plate 220, and its upper side contacts the container of the annular cooler body 100 that carries high-temperature materials; the container of the annular cooler body 100 that carries high-temperature materials is annular, and a plurality of the roller chain support assemblies 200 are arranged in a ring shape on the annular cooler body 100.

[0054] The roller chain supported annular cooler provided in the embodiment of the present application includes an annular cooler body 100 and a roller chain supporting assembly 200 .

[0055] Among them, the ring cooler body 100 has a container for carrying high-temperature materials, and the container performs circular motion on the ring cooler body 100 to achieve cooling of the high-temperature materials. In the existing ring coolers, the container for carrying high-temperature materials is usually borne by support rollers, resulting in large wheel pressure, large diameter of the support rollers, and large contact stress between the track 124 and the rollers.

[0056] The roller chain support assembly 200 includes a roller chain support frame 210, a roller plate 220 and a closed loop roller chain 230. The technical solution replaces the support roller with a roller chain support assembly 200 arranged in an annular manner. The container carrying the high temperature material of the annular cooler body 100 is annular. Under the action of the driving device, the container carrying the high temperature material performs a circular motion on the roller chain support assembly 200 arranged in an annular manner. During the circular operation of the annular roller chain 200 carrying the high temperature material, the closed loop roller chain 2 30 is in the form of a crawler track. One side of the closed-loop roller chain 230 contacts the roller plate 220, and the other side contacts the container carrying the high-temperature material to cause friction rolling. When the end roller of the roller plate 220 climbs above the roller plate 220, it begins to be stressed. At the same time, the frontmost roller above the roller plate 220 gradually gets rid of the stress and moves to the bottom of the roller plate 220. In this way, the closed-loop roller chain 230 rolls continuously from front to back and from top to bottom along the surface of the roller plate 220 to support the rotation of the container carrying the high-temperature material.

[0057] The new type of roller chain supported annular cooler adopted in the technical solution has an improved structure, which is compact and reasonable. The traditional one-point support of each supporting roller is changed to multiple-point support of each roller chain, which greatly reduces the wheel pressure, reduces the roller diameter and the contact stress between the track 124 and the roller, and at the same time reduces the diameter of the supporting roller, which saves more installation space and makes the setting of the annular cooler more flexible.

[0058] like Figure 1-4 As shown, the annular cooler body 100 includes: a frame 110, the frame 110 is set on the ground or an installation platform, and the roller chain support assembly 200 is set on the frame 110; a rotating body 120, the rotating body 120 is set on the roller chain support assembly 200, and the rotating body 120 performs a rotating motion on the roller chain support assembly 200; and a driving assembly, the driving assembly drives the rotating body 120 to perform a circular motion on the frame 110.

[0059] In this technical solution, the ring cooler body 100 includes a frame 110, a rotating body 120 and a driving assembly, wherein the rotating body 120 is a container for carrying high-level materials, the rotating body 120 is arranged on the frame 110, and the roller chain support assembly 200 is arranged between the rotating body 120 and the frame 110.

[0060] The rotating body 120 is a circular material conveying channel.

[0061] During actual use, the rotating body 120 performs circular motion on the frame 110 through the roller chain support assembly 200, and the high-temperature material to be cooled is poured into the rotating body 120 through the external material discharge port. The rotating body 120 drives the material to perform circular motion while performing circular motion, and the material is cooled at the same time, and then the high-temperature material is dumped to complete the cooling of the high-temperature material.

[0062] like Figure 1-4 As shown, the rotating body 120 includes: a rotating frame 121, which is arranged on the frame 110, and the rotating frame 121 is annular; a trolley 122, the number of the trolleys 122 is several, and the several trolleys 122 are arranged at the bottom of the rotating frame 121 in a first-order connected manner; a guardrail 123, the guardrail 123 is arranged on the inner ring side and the outer ring side of the upper part of the rotating frame 121, and the guardrail 123 and the trolley 122 form an annular material device; a track 124, the track 124 is arranged below the rotating frame 121, and the track 124 is arranged above the roller chain support assembly 200.

[0063] In this technical solution, the rotating body 120 includes a rotating frame 121 , a trolley 122 , a guardrail 123 and a track 124 .

[0064] The track 124 has an outer ring track and an inner ring track, and the outer ring track and the inner ring track, and the track 124 is arranged on the upper part of the roller chain support assembly 200 .

[0065] Wherein, the revolving frame 121 is disposed on the track 124;

[0066] The trolley 122 is disposed end to end at the bottom of the revolving frame 121 , and the trolley 122 can be understood as the bottom plate of the revolving frame 121 .

[0067] The baffles 123 are arranged on the inner ring side and the outer ring side of the revolving frame 121 , and the revolving frame 121 , the trolley 122 , and the baffles 123 together form a space for accommodating and controlling high-temperature materials.

[0068] In actual use, the high-temperature material is poured into the rotating frame 121, and the rotating frame 121 is driven by the driving device to rotate on the frame 110, thereby realizing cooling of the material.

[0069] like Figure 1-4 As shown, the frame 110 includes: a plane beam, which is a circular ring-shaped plane beam, and a plurality of groups of roller chain support units are arranged on the upper surface of the plane beam in inner and outer circles, and the bottom plate of the roller chain support frame 210 is connected to the plane beam; inner columns, which are a plurality of inner columns and are arranged at intervals on the inner ring side of the plane beam; and outer columns, which are a plurality of outer columns and are arranged at intervals on the outer ring side of the plane beam.

[0070] In this technical solution, the frame 110 includes a plane beam, an inner column and an outer column.

[0071] Among them, the plane beams, inner columns and outer columns are all made of standard rolled H-shaped steel.

[0072] The plane beam provides an installation foundation and an operating platform for the roller chain support assembly 200 and the rotating body 120 .

[0073] Among them, inner columns and outer columns are arranged on the inner ring side and the outer ring side of the plane beam, which increases the stability of the plane beam and thus improves the stability of the operation of the ring cooler.

[0074] like Figure 1-4 As shown, the trolley 122 includes: a bottom plate, which is arranged at the bottom of the rotating frame 121 and connected to the bottom; a linkage shaft, which is set at one end of the bottom plate, and the linkage shaft is inserted into the rotating frame 121 and hinged to the rotating frame 121.

[0075] In this technical solution, the trolley 122 includes a base plate and a connecting shaft.

[0076] The bottom plate is connected end to end at the bottom of the rotating frame 121 , a linkage shaft is provided at one end of the bottom plate and is hinged to the rotating frame 121 , and the linkage between the bottom plate and the rotating frame 121 is realized through the linkage shaft.

[0077] like Figure 1-4 As shown, the frame 110 also includes anti-tipping side rails, which include curved rail sections and annular straight rail sections; the trolley 122 also includes an anti-tipping roller arm wheel 130, which is arranged at the other end of the bottom plate, and the anti-tipping roller arm wheel 130 runs on the anti-tipping side rails; when the anti-tipping roller arm wheel 130 runs on the annular straight rail section of the anti-tipping side rails, the trolley 122 moves materials horizontally, and when the anti-tipping roller arm wheel 130 runs on the curved rail section of the anti-tipping side rails, the trolley 122 overturns and unloads materials.

[0078] In this technical solution, the anti-tipping side rails include a curved rail section and an annular straight rail section, and the trolley 122 also includes an anti-tipping roller arm wheel 130, which is arranged at the other end of the base plate and runs on the anti-tipping side rails.

[0079] It can be understood that the highest of the curved track section of the track 124 is higher than the circular straight track section, that is, it runs on the anti-tipping side rail, and has a tendency to run smoothly to the upward direction, to the downward direction, and to the stable operation. When the anti-tipping roller arm wheel 130 runs to the best point of the curved track section, the anti-tipping roller arm wheel 130 is driven to be lifted by the tipping side rail. After the anti-tipping roller arm wheel 130 is lifted, it drives one end of the bottom plate to rise, so that the bottom plate changes from a horizontal state to an inclined state away from the anti-tipping roller arm wheel 130, and the material can be unloaded from the annular cooler.

[0080] As the rotating body 120 performs circular motion, the anti-tilting roller arm wheel 130 moves from the curved track section to the annular straight track. At this time, the bottom plate returns to a horizontal state and starts to run smoothly.

[0081] like Figure 1-4 As shown, the ring cooler body 100 further includes side stop rollers 140 , which are disposed on the rotary frame 121 to prevent deviation and continuous rotation.

[0082] In this technical solution, the annular cooler body 100 also includes a side stop roller 140, one end of which is arranged on one side of the rotating frame 121. It can be understood that the other end of the side stop roller 140 is arranged on the frame 110, and the frame 110 is also provided with an annular track 124 for the side stop roller 140 to slide. Under the limitation of the side stop roller 140, the rotating frame 121 can be effectively prevented from continuously rotating and deviating, thereby effectively improving the stable operation of the annular cooler.

[0083] like Figure 1-4 As shown, the ring cooler body 100 further includes: a blower, which is disposed below the trolley 122 and is used to accelerate the cooling of high-temperature materials.

[0084] In this technical solution, the ring cooler body 100 also includes a blower, which is arranged under the trolley 122. When the rotating body 120 drives the high-temperature material to perform circular motion, the blower blows air under the trolley 122 to further improve the speed and effect of cooling the high-temperature material.

[0085] This technical solution effectively improves the technical effect of the ring cooler.

[0086] like Figure 1-4 As shown, the closed loop roller chain 230 includes: a chain plate, which is closed and surrounds the roller plate 220; a roller member, which is rotatably arranged on the chain plate; and a pin shaft, through which the chain plate and the roller member are rotatably connected.

[0087] In this technical solution, the closed loop roller chain 230 includes chain plates, roller elements and pins.

[0088] The chain plate is the track of the closed loop roller chain 230, and a plurality of roller elements are arranged on the chain plate. Meanwhile, a single roller element is connected to the chain plate through a pin shaft, and the roller element can rotate relative to the chain plate.

[0089] This arrangement not only realizes the overall rotation of the closed-loop roller chain 230 around the raceway plate 220, but also realizes the individual rotation of the roller components, effectively reducing the contact stress generated between the lower supporting components and the rotating body 120 when the rotating body 120 is running.

[0090] like Figure 1-4 As shown, a guide groove is provided on the upper side of the roller plate 220, and the closed loop roller chain 230 at the upper end of the roller plate 220 has its lower side close to the guide groove of the roller plate 220, and its upper side contacts the container of the ring cooler body 100 carrying high temperature materials.

[0091] In this technical solution, a guide groove is opened on the upper side of the rolling plate, and the closed-loop roller chain 230 on the upper side of the rolling plate 220 has its lower side embedded in the guide groove of the rolling plate 220, and its upper side is tightly attached to the lower end of the annular body. Under this arrangement, the closed-loop roller chain 230 can be effectively prevented from running off the track, thereby affecting the operation of the rotating body 120, and the stability of the operation of the annular cooler can be effectively improved.
