Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a conveying device with heat exchange function. Background Technology

[0002] Conveying devices are used to transport materials from one location to another. They usually have a single function. In some special applications, by adding modules with specific functions, the conveying device can achieve a certain function while conveying materials. For example, adding a weighing module can enable the conveying device to have a precise metering function. Such devices basically include a housing, a material inlet and outlet, a spiral conveying guide vane set in the housing, a shaft for fixing the guide vane, and a bearing for fixing the guide vane shaft.

[0003] Currently, in some special applications, such as solving the problem of cooling high-temperature materials during transportation and heating and dehydrating materials to be processed, common high-temperature material conveying equipment often uses external jacket cooling circulating water for cooling. The heat carried away by the cooling water causes the water temperature to rise, requiring additional energy to cool the circulating water. The overall energy consumption is generally high. Moreover, when the moisture content of the materials to be processed is high, directly feeding them into the heating equipment will increase the equipment load and greatly increase the heating power. Therefore, we provide a conveying device with heat exchange function to solve this problem. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a conveying device with heat exchange function.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a conveying device with heat exchange function, including an outer cylinder. Two sets of support seats are installed on the outer side of the outer cylinder. A material transfer mechanism is movably arranged in the inner cavity of the outer cylinder. Both ends of the material transfer mechanism pass through the outer cylinder and extend to its outer side. A left sealing end cap and a right sealing end cap are screwed to both sides of the outer cylinder, respectively. The left and right sealing end caps are movably sleeved on the outer side of the material transfer mechanism. A discharge cylinder is screwed to the left end of the material transfer mechanism. A first sprocket is installed on the outer side of the discharge cylinder, and a drive mechanism is engaged on the outer side of the first sprocket.

[0006] The material transfer mechanism includes a rotating drum screwed to the discharge cylinder. External spiral blades are installed at equal intervals on the outer side of the rotating drum. The size of the external spiral blades matches the size of the inner cavity of the outer drum. Internal spiral blades are installed at equal intervals in the inner cavity of the rotating drum. A fixed rotating assembly is rotatably connected to the right end of the rotating drum. A feed elbow pipe is connected to the right end of the fixed rotating assembly.

[0007] In a further preferred embodiment, the drive mechanism includes a transmission chain that meshes with a first sprocket, and a second sprocket is also meshed within the inner cavity of the transmission chain. A base is provided below the outer cylinder, and a reduction motor is mounted on the upper end of the base. The second sprocket is mounted on the outer side of the output end of the reduction motor.

[0008] In a further preferred embodiment, a feed inlet is provided on the upper left side of the outer cylinder, a discharge outlet is provided on the lower right side of the outer cylinder, and a steam vent is provided on the upper right side of the outer cylinder.

[0009] In a further preferred embodiment, the fixed rotating assembly includes a sleeve plate that is movably sleeved with the rotating drum. Through holes are equidistantly arranged on the outer side of the sleeve plate. A fixed plate is connected to the left side of the feed elbow pipe. Fixed bolts are equidistantly inserted on the outer side of the fixed plate. All fixed bolts pass through the through holes and are screwed with fixed nuts. An installation groove is provided on the left side of the fixed plate, and the right side of the rotating drum is movably sleeved in the inner cavity of the installation groove.

[0010] In a further preferred embodiment, an annular groove is provided on the left side of the fixed disk, and an annular retaining ring is integrally connected to the right side of the rotating drum, the annular retaining ring being movably fitted into the inner cavity of the annular groove.

[0011] In a further preferred embodiment, a sealing groove is provided on the left side of the fixed plate, and a sealing gasket is fitted into the inner cavity of the sealing groove. The left side of the sealing gasket is in contact with the right side of the rotating drum, and the sealing gasket is made of high-temperature resistant rubber material.

[0012] In a further preferred embodiment, a support sleeve is installed on the outer side of the feed elbow pipe, and a support frame is connected to the lower end of the support sleeve.

[0013] In a further preferred embodiment, an insulation sleeve is fitted onto the outer side of the outer cylinder, and the insulation sleeve is made of silicate sepiolite composite insulation material.

[0014] The advantages and beneficial effects of this utility model are as follows: 1. The first sprocket is driven to rotate by the drive mechanism, and the first sprocket drives the discharge cylinder and the rotating cylinder of the material transfer mechanism to rotate. Low-temperature materials are introduced into the inner cavity of the outer cylinder through the feed port, and high-temperature materials are introduced into the inner cavity of the rotating cylinder through the feed elbow pipe. When the rotating cylinder rotates, the inner spiral blades on the inner wall of the rotating cylinder and the outer spiral blades welded to the outer wall rotate in opposite directions. Thus, the inner spiral blades and the outer spiral blades respectively push the high-temperature materials and the low-temperature materials to flow in opposite directions. At the same time, the inner spiral blades and the outer spiral blades also have the function of increasing the heat exchange area and improving the heat exchange efficiency. Finally, the high-temperature materials after cooling are discharged from the discharge cylinder, while the low-temperature materials are discharged from the discharge port, and the water vapor generated after heating is discharged from the exhaust port, which facilitates effective material transportation.

[0015] 2. By designing a fixed rotating assembly between the feed elbow and the rotating drum, the right side of the drum rotates within the mounting groove on the left side of the fixed plate when the drum rotates. The fixed plate and the sleeve plate are fixed together by bolts and nuts. This allows the feed elbow to stably convey materials without rotating when the drum rotates. The right side of the drum is limited in rotation by a ring retainer within the annular groove on the left side of the fixed plate, effectively improving the rotational stability of the drum. Furthermore, by fitting a sealing gasket into the sealing groove on the left side of the fixed plate, the sealing between the feed elbow and the rotating drum is effectively increased, preventing hot air from escaping through gaps and effectively improving the insulation effect.

[0016] Compared with existing technologies, this utility model has a reasonable structural design and strong practicality. This utility model uses the waste heat of high-temperature materials to preheat and dehydrate low-temperature materials to be treated, thereby reducing the moisture content of the materials to be treated and raising their temperature. This can reduce the heating energy consumption of the downstream heating equipment and effectively cool down the high-temperature materials, thereby reducing the energy consumption of the downstream cooling equipment. Especially for continuously operating equipment, this effectively reduces the operating cost and thus effectively increases the heat exchange and conveying effect. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0026] Reference Figure 1-2 As shown, a conveying device with heat exchange function includes an outer cylinder 1. Two sets of support seats 2 are installed on the outside of the outer cylinder 1. A feed inlet 3 is provided on the upper left side of the outer cylinder 1, and a discharge outlet 10 is provided on the lower right side of the outer cylinder 1. A steam vent 11 is provided on the upper right side of the outer cylinder 1. Low-temperature materials are introduced into the inner cavity of the outer cylinder 1 through the feed inlet 3, while high-temperature materials are introduced into the inner cavity of the transfer mechanism 4. After the low-temperature materials enter the outer cylinder 1, they are located outside the transfer mechanism 4. Thus, the heat of the high-temperature materials in the inner cavity of the transfer mechanism 4 is transferred to the low-temperature materials, thereby performing heat exchange treatment. This facilitates the cooling of high-temperature materials that need to be cooled by heat transfer, while low-temperature materials that need to be heated and dehydrated receive the heat transferred from the high-temperature materials and are heated and dehydrated. Water vapor is discharged through the steam vent 11, and the low-temperature materials after heating and dehydration are discharged from the discharge outlet 10, which effectively achieves the heat exchange treatment effect during the conveying process.

[0027] An insulation sleeve 14 is fitted onto the outer side of the outer cylinder 1. The insulation sleeve 14 is made of silicate sepiolite composite insulation material. The insulation sleeve 14 made of silicate sepiolite composite insulation material plays a role in heat insulation of the outer cylinder 1, preventing the heat transferred from high-temperature materials to low-temperature materials from being quickly dissipated and affecting the heating and dehydration effect of low-temperature materials.

[0028] Reference Figure 6-7As shown, a first sprocket 8 is installed on the outer side of the discharge cylinder 7. A drive mechanism 9 is engaged on the outer side of the first sprocket 8. The drive mechanism 9 includes a transmission chain 94 that meshes with the first sprocket 8. A second sprocket 93 is also engaged in the inner cavity of the transmission chain 94. A base 91 is provided below the outer cylinder 1. A reduction motor 92 is installed at the upper end of the base 91. The second sprocket 93 is installed on the outer side of the output end of the reduction motor 92.

[0029] The switch of the geared motor 92 is activated by an external switch. The output of the geared motor 92 drives the second sprocket 93 to rotate. The second sprocket 93 drives the first sprocket 8 meshed with it to rotate. The first sprocket 8 drives another first sprocket 8 meshed in its inner cavity to rotate. The first sprocket 8 drives the discharge cylinder 7 and the material transfer mechanism 4 to rotate, which facilitates the material transfer mechanism 4 to transport materials.

[0030] Reference Figure 1-5 As shown, a material transfer mechanism 4 is movably installed in the inner cavity of the outer cylinder 1. Both ends of the material transfer mechanism 4 pass through the outer cylinder 1 and extend to its outer side. A left sealing end cap 15 and a right sealing end cap 16 are screwed to both sides of the outer cylinder 1, respectively. The left sealing end cap 15 and the right sealing end cap 16 are movably sleeved on the outer side of the material transfer mechanism 4. A discharge cylinder 7 is screwed to the left end of the material transfer mechanism 4. The material transfer mechanism 4 includes a rotating cylinder 41 screwed to the discharge cylinder 7. External spiral blades 43 are installed at equal intervals on the outer side of the rotating cylinder 41. The size of the external spiral blades 43 matches the inner cavity of the outer cylinder 1. Internal spiral blades 42 are installed at equal intervals in the inner cavity of the rotating cylinder 41. A fixed rotating assembly 5 is rotatably connected to the right end of the rotating cylinder 41. A feed elbow pipe 6 is connected to the right end of the fixed rotating assembly 5.

[0031] When the discharge cylinder 7 rotates, it drives the rotating cylinder 41 of the material transfer mechanism 4 to rotate. Low-temperature materials are introduced into the inner cavity of the outer cylinder 1 through the feed inlet 3, while high-temperature materials are introduced into the inner cavity of the rotating cylinder 41 through the feed elbow pipe 6. As the rotating cylinder 41 rotates, the inner spiral blades 42 on the inner wall of the rotating cylinder 41 and the outer spiral blades 43 welded to the outer wall rotate in opposite directions. This causes the inner spiral blades 42 and the outer spiral blades 43 to push the high-temperature and low-temperature materials to flow in opposite directions, respectively. Based on the principle of counter-current heat exchange, counter-current heat exchange means that the high-temperature medium (high-temperature material) and the low-temperature medium (low-temperature material) located on both sides of the heat exchange surface flow towards each other along the heat exchange surface. The outlet of the high-temperature medium (high-temperature material) is close to the inlet of the low-temperature medium (low-temperature material), and the inlet of the low-temperature medium (low-temperature material) is close to the outlet of the high-temperature medium (high-temperature material). During the flow process, the high-temperature medium (high-temperature material) is cooled down, while the low-temperature medium (low-temperature material) is heated and dehydrated due to the absorption of heat. At the same time, the inner spiral blade 42 and the outer spiral blade 43 also increase the heat exchange area and improve the heat exchange efficiency. Finally, the high-temperature material after cooling is discharged from the discharge cylinder 7, while the low-temperature material is discharged from the discharge port 10, and the water vapor generated after heating is discharged from the exhaust port 11, which facilitates effective material conveying.

[0032] The fixed rotating assembly 5 includes a sleeve 52 that is movably fitted with the rotating drum 41. Through holes are provided at equal intervals on the outer side of the sleeve 52. A fixed plate 51 is connected to the left side of the feed elbow pipe 6. Fixed bolts 53 are inserted at equal intervals on the outer side of the fixed plate 51. All fixed bolts 53 pass through the through holes and are screwed with fixed nuts 54. An installation groove 55 is provided on the left side of the fixed plate 51. The right side of the rotating drum 41 is movably fitted into the inner cavity of the installation groove 55. An annular groove 57 is provided on the left side of the fixed plate 51. An annular retaining ring 44 is integrally connected to the right side of the rotating drum 41. The annular retaining ring 44 is movably fitted into the inner cavity of the annular groove 57. A sealing groove 56 is provided on the left side of the fixed plate 51. A sealing gasket 58 is fitted into the inner cavity of the sealing groove 56. The left side of the sealing gasket 58 fits against the right side of the rotating drum 41. The sealing gasket 58 is made of high-temperature resistant rubber material.

[0033] By designing a fixed rotating assembly 5 between the feed elbow 6 and the rotating drum 41, when the rotating drum 41 rotates, the right side of the rotating drum 41 rotates within the mounting groove 55 on the left side of the fixed plate 51. The fixed plate 51 and the sleeve plate 52 are screwed together by the cooperation of the fixing bolts 53 and the fixing nuts 54. This allows the feed elbow 6 to stably convey materials without rotating when the rotating drum 41 rotates. Furthermore, the right side of the rotating drum 41 is limited to rotating within the annular groove 57 on the left side of the fixed plate 51 by the annular retaining ring 44, which effectively improves the rotational stability of the rotating drum 41. In addition, by fitting a sealing gasket 58 into the sealing groove 56 on the left side of the fixed plate 51, the sealing performance between the feed elbow 6 and the rotating drum 41 is effectively increased, preventing hot air from escaping from the gaps and effectively improving the heat preservation effect.

[0034] A support sleeve 12 is installed on the outside of the feed elbow pipe 6, and a support frame 13 is connected to the lower end of the support sleeve 12, which facilitates stable support of the feed elbow pipe 6 and facilitates stable conveying and introduction of high-temperature materials into the inner cavity of the rotating drum 41.

[0035] Working Principle: In use, the external switch activates the geared motor 92, which in turn drives the second sprocket 93 to rotate. The second sprocket 93 then drives the meshing first sprocket 8 to rotate, which in turn drives another meshing first sprocket 8 within its inner cavity to rotate. This first sprocket 8, in turn, drives the discharge cylinder 7 and the rotating drum 41 of the transfer mechanism 4 to rotate. Low-temperature materials are introduced into the inner cavity of the outer cylinder 1 through the feed inlet 3, while high-temperature materials are introduced into the inner cavity of the rotating drum 41 through the feed elbow pipe 6. As the rotating drum 41 rotates, the inner spiral blades 42 on the inner wall of the rotating drum 41 and the outer spiral blades 43 welded to the outer wall rotate in opposite directions. This causes the inner spiral blades 42 and the outer spiral blades 43 to push the high-temperature and low-temperature materials to flow in opposite directions, respectively. Based on the principle of "counter-current" heat exchange, counter-current heat exchange refers to the high-temperature medium (high-temperature material) and the low-temperature medium (low-temperature material) located on opposite sides of the heat exchange surface. The materials flow in opposite directions along the heat exchange surface. The outlet of the low-temperature medium (low-temperature material) is close to the inlet of the high-temperature medium (high-temperature material), and the inlet of the low-temperature medium (low-temperature material) is close to the outlet of the high-temperature medium (high-temperature material). During the flow, the high-temperature medium (high-temperature material) is cooled down, while the low-temperature medium (low-temperature material) is heated due to the absorption of heat. Thus, the low-temperature material is heated and dehydrated. At the same time, the inner spiral blades 42 and the outer spiral blades 43 also increase the heat exchange area and improve the heat exchange efficiency. Finally, the high-temperature material after cooling is discharged from the discharge cylinder 7, while the low-temperature material is discharged from the discharge port 10. The water vapor generated after heating is discharged from the exhaust port 11, which facilitates effective material transportation. The insulation sleeve 14 made of silicate sepiolite composite insulation material provides insulation for the outer cylinder 1, preventing the heat transferred from the high-temperature material to the low-temperature material from dissipating rapidly and affecting the heating and dehydration effect of the low-temperature material.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
