Description

Technical Field

[0001] The utility model relates to the technical field of boiling cooling beds, in particular to a directional conveying device for a boiling cooling bed. Background Art

[0002] The boiling cooling bed is a device that cools down high-temperature used sand. It can cool the used sand to a certain temperature for subsequent use. During the cooling process, the used sand often requires a conveying device to transport the whole sand to ensure stable transportation of the used sand. However, with the continuous development of production technology, the performance requirements for the boiling cooling bed are getting higher and higher. Especially in the cooling and conveying process of used sand and other materials, traditional conveying devices can no longer meet the needs of modern production.

[0003] The existing fluidized bed conveying device uses a vibration motor to drive the vibrating conveying plate to vibrate so as to transport the old sand. However, during the transportation of the old sand, it may fall from both ends of the vibrating conveying plate into the fluidized bed and accumulate, causing the device to fail to operate normally.

[0004] The existing patent (publication number: CN210001040U) is a boiling cooling bed directional conveying device, including a boiling cooling bed body, a blower is fixedly connected to the left end of the boiling cooling bed body, and a feed port is opened at the upper end of the boiling cooling bed body, a vibration motor is fixedly connected to the front end of the boiling cooling bed body, and the output end of the vibration motor passes through the front end of the boiling cooling bed body and extends to the inside of the boiling cooling bed body, a vibration conveying plate is fixedly installed at the output end of the vibration motor, and the vibration conveying plate is movably connected to the inside of the boiling cooling bed body, and a discharge port is arranged at the right end of the boiling cooling bed body.

At the same time, the existing conveying device cannot evenly transport cold air to the old sand, which will lead to a decrease in the cooling efficiency of the old sand.

[0006] Therefore, a boiling cooling bed directional conveying device is proposed. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The present application is provided with a directional conveying mechanism, which starts a driving motor. The rotation of the driving motor drives the gear at its output end to rotate.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figures 1 to 7 , the utility model provides a technical solution:

[0032] A fluidized bed directional conveying device comprises a cooling bed body 1, a directional conveying mechanism 2 is arranged inside the cooling bed body 1, a cooling mechanism 3 is arranged at the bottom of the cooling bed body 1, and an exhaust assembly 4 is arranged at the top of the cooling bed body 1;

[0033] The directional conveying mechanism 2 includes a sealing door 21, a conveying cylinder 22, a feeding spiral blade 23, an air hole 24, a gear ring 25, a driving motor 26, a gear 27 and a support and limit assembly 28. The two sealing doors 21 are arranged on both sides of the cooling bed 1, the conveying cylinder 22 is arranged in the middle of the two sealing doors 21, the feeding spiral blade 23 is fixedly connected to the inner wall of the conveying cylinder 22, a plurality of air holes 24 are opened on the side wall of the conveying cylinder 22 and are arranged at equal intervals, the gear ring 25 is fixedly connected to the middle of the conveying cylinder 22, the driving motor 26 is bolted to the bottom of the cooling bed 1, the gear 27 is fixedly connected to the output end of the driving motor 26, the gear 27 is meshed with the gear ring 25, and the support and limit assembly 28 is arranged on the side wall of the sealing door 21.

[0034] Specifically, Figure 7 As shown, the support and limiting assembly 28 includes a limiting ring 281, a mounting frame 282 and a supporting limiting wheel 283. The two limiting rings 281 are respectively fixedly connected to the two ends of the conveying cylinder 22, and the four mounting frames 282 are fixedly connected to the inner wall of the sealing door 21. The supporting limiting wheel 283 is arranged in the middle of the mounting frame 282, and the supporting limiting wheel 283 is arranged in the middle of the limiting ring 281.

[0035] Specifically, Figure 7 As shown, a feed hopper 7 and a discharge hopper 8 are respectively provided on the side walls of the two sets of sealing doors 21 .

[0036] The old sand material is introduced into the conveying cylinder 22 through the feed hopper 7 arranged on the side wall of the sealing door 21, and the driving motor 26 is started. The rotation of the driving motor 26 drives the gear 27 at its output end to rotate. Since the gear 27 is meshed with the toothed ring 25 fixedly connected to the middle part of the conveying cylinder 22, the rotation of the gear 27 will drive the toothed ring 25 and the conveying cylinder 22 to rotate together, supporting the limiting wheel 283 to move on the side wall of the limiting ring 281. This process will ensure the stable operation of the conveying cylinder 22 and prevent it from being offset or shaking due to the weight of the old sand material or the rotational force. As the conveying cylinder 22 rotates, the feeding spiral blades 23 on its inner wall will push the material to move forward along the axial direction of the conveying cylinder 22 to realize the directional conveying of the material. Through the multiple air holes 24, cold air can enter the interior of the conveying cylinder 22 to cool the old sand material. In this way, the old sand material can be dispersed and directional conveyed, which can prevent the problem of accumulation of old sand raw materials during the conveying process, and improve the cooling effect of the directional conveying of the old sand material.

[0037] Specifically, Figure 6As shown, the cooling mechanism 3 includes a fan 31, an air supply pipe 32, an air outlet 33 and an air intake filter assembly 34. Two sets of fans 31 are bolted to the bottom of the cooling bed 1, and two sets of air supply pipes 32 are fixedly connected to the bottom of the cooling bed 1. The fans 31 are connected and matched with the air supply pipes 32. Multiple air outlets 33 are arranged on the side walls of the air supply pipes 32 and are inclined. The air intake filter assembly 34 is arranged at the air inlet end of the fan 31.

[0038] Specifically, Figure 6 As shown, the air intake filter assembly 34 includes a filter element 341 and a mounting ring 342 . The filter element 341 is disposed at the air intake end of the fan 31 . The mounting ring 342 is threadedly connected to the air intake end of the fan 31 . The filter element 341 is located between the fan 31 and the mounting ring 342 .

[0039] Specifically, Figure 3 As shown, the exhaust assembly 4 includes an exhaust pipe 41 and a protective top 42 . The two exhaust pipes 41 are arranged on the top of the cooling bed 1 , and the protective top 42 is arranged on the top of the exhaust pipe 41 .

[0040] Specifically, Figure 6 As shown, a bidirectional spiral blade 5 is fixedly connected to the inner wall of the air supply pipe 32 , and the bidirectional spiral blade 5 is used to transport cold air to both ends of the air supply pipe 32 .

[0041] Specifically, Figure 3 As shown, a deflector 6 is provided at the bottom of the exhaust pipe 41, and the deflector 6 is arranged in an umbrella shape.

[0042] During use, when the fan 31 is started, air is sucked in through its air inlet end, filtered by the filter element 341 in the air intake filter assembly 34, and then enters the air supply pipe 32. The bidirectional spiral blades 5 in the air supply pipe 32 will evenly transport the cold air to the two ends of the air supply pipe 32, and blow it toward the material in the conveying cylinder 22 through the air outlet head 33 inclinedly arranged on the side wall, so as to cool the material. During the cooling process, the hot air generated is discharged through the exhaust pipe 41, and the protective top 42 can prevent the external environment from interfering with and polluting the exhaust pipe 41. The air guide 6 at the bottom of the exhaust pipe 41 is arranged in an umbrella shape, and its function is to guide the exhausted hot air to flow upward to avoid the hot air being directly discharged downward and causing adverse effects on the surrounding environment. At the same time, the design of the air guide 6 can also reduce the diffusion range of the hot air and improve the exhaust efficiency. In this way, the rapid cooling of the material is achieved and the cooling efficiency of the old sand material is improved.

[0043] By adopting the above technical scheme, the problem that the existing boiling cooling bed directional conveying device is unable to disperse and directional convey the old sand is solved. In the process of conveying the old sand, the old sand is prone to accumulation. The accumulated old sand will make it difficult for the heat inside the old sand to dissipate quickly. At the same time, the existing conveying device cannot evenly convey cold air to the old sand, which will lead to a decrease in the cooling efficiency of the old sand.

[0044] Working principle: When the present application is in use, first, the old sand material is introduced into the conveying cylinder 22 through the feed hopper 7 arranged on the side wall of the sealing door 21, and the driving motor 26 is started. The rotation of the driving motor 26 drives the gear 27 at its output end to rotate. Since the gear 27 is meshed with the toothed ring 25 fixedly connected to the middle part of the conveying cylinder 22, the rotation of the gear 27 drives the toothed ring 25 and the conveying cylinder 22 to rotate together, and the supporting limiting wheel 283 moves on the side wall of the limiting ring 281. This process ensures the stable operation of the conveying cylinder 22 and prevents it from deflecting or shaking due to the weight of the old sand material or the rotational force. As the conveying cylinder 22 rotates, the feeding spiral blades 23 on its inner wall push the material to move forward along the axial direction of the conveying cylinder 22, realizing the material The directional conveying of the material, through the multiple air holes 24, cold air can enter the interior of the conveying cylinder 22 to cool the old sand material. When the fan 31 is started, air is sucked in through its air inlet end, filtered by the filter element 341 in the air intake filter assembly 34, and then enters the air supply pipe 32. The bidirectional spiral blades 5 in the air supply pipe 32 will evenly convey the cold air to the two ends of the air supply pipe 32, and blow it to the material in the conveying cylinder 22 through the air outlet 33 obliquely arranged on the side wall to achieve cooling of the material. In this way, the old sand material can be dispersedly conveyed in a directional manner, the problem of accumulation of the old sand raw materials during the conveying process can be prevented, and the cold air can be evenly conveyed to the old sand raw materials being conveyed, thereby improving the cooling effect of the directional conveying of the old sand materials.
