Description

Technical Field

[0001] This application relates to the field of cooling conveying technology, and in particular to a lime powder conveying device with cooling function. Background Technology

[0002] Lime powder usually refers to slaked lime, also known as calcium oxide. Its main uses include building materials, steel metallurgy, environmental protection, agricultural production, and the chemical industry. The production of lime powder generates high temperatures. The relevant technology uses natural cooling to cool the lime powder, specifically by placing it in a container and allowing it to cool naturally before sealing it.

[0003] Regarding the aforementioned technologies, natural cooling requires a relatively long time. During this extended natural cooling period, lime powder that fails to cool down in time may undergo a chemical reaction, reducing its purity. Therefore, improvements are needed to address this issue. Summary of the Invention

[0004] In order to improve the cooling effect of lime powder, this application provides a lime powder conveying device with cooling function.

[0005] The lime powder conveying device with cooling function provided in this application adopts the following technical solution:

[0006] A lime powder conveying device with cooling function includes a mounting frame, on which a conveying cylinder is rotatably mounted. An inlet is located at the top of one end of the conveying cylinder, and an outlet is located at the bottom of the other end. Spiral fan blades are coaxially mounted on the inner wall of the conveying cylinder. A first rotating block is rotatably mounted on the inner wall of one end of the conveying cylinder, and a second rotating block is rotatably mounted on the inner wall of the other end of the conveying cylinder. A cooling structure for cooling the lime powder is provided between the first and second rotating blocks.

[0007] By adopting the above technical solution, when the conveying cylinder rotates, the spiral fan blades set on the inner wall of the rotating cylinder can drive the lime powder from the inlet to the outlet. The cooling structure set on the first rotating block and the second rotating block can cool the lime powder during the conveying process, thus facilitating the preservation of the lime powder.

[0008] Optionally, a first connecting groove is formed in the first rotating block, and a second connecting groove is formed in the second rotating block. The cooling structure includes a rotating tube, a cooling tube, and a water outlet pipe. The water outlet pipe is coaxially rotatably disposed on the side of the conveying cylinder away from the first rotating block, and its end passing through the conveying cylinder communicates with the second connecting groove. The rotating tube is coaxially disposed inside the conveying cylinder, with one end of the rotating tube disposed on the first rotating block and communicating with the first connecting groove. A portion of the rotating tube is disposed inside the water outlet pipe, and the end of the rotating tube away from the first rotating block extends out of the water outlet pipe. Multiple cooling tubes are provided, with one end of each cooling tube connected to the first rotating block and communicating with the first connecting groove, and the other end of each cooling tube connected to the second rotating block and communicating with the second connecting groove. A circulation component is provided on the rotating tube and the water outlet pipe. The circulation component is used to draw water from the rotating tube and inject cooling water into the water outlet pipe.

[0009] By adopting the above technical solution, the circulation component can transport cooling water through the gap between the rotating pipe and the outlet pipe to the second connecting groove, and then transport the cooling water from the second connecting groove to each cooling pipe, thereby cooling the lime powder during transportation through the cooling pipe. The heated water in the cooling pipe then enters the rotating pipe through the first connecting groove, and is discharged through the rotating pipe. The circulation component can cool the discharged hot water and recycle it, thereby improving the utilization rate of resources.

[0010] Optionally, the circulation assembly includes a circulating water pump, a circulating water tank, a circulating water outlet pipe, a circulating water inlet pipe, and a heat dissipation plate. The circulating water tank is located at the end of the water outlet pipe away from the conveying cylinder, and the water outlet pipe is rotatably mounted on the side wall of the circulating water tank and communicates with the interior of the circulating water tank. The end of the rotating pipe away from the first rotating block is located inside the circulating water tank. The circulating water outlet pipe is rotatably connected to the end of the rotating pipe away from the first rotating block. The end of the circulating water outlet pipe away from the rotating pipe passes through the bottom wall of the circulating water tank and is connected to the inlet of the circulating water pump. The circulating water inlet pipe is located at the outlet of the circulating water pump, and the end of the circulating water inlet pipe away from the circulating water pump communicates with the side wall of the circulating water tank. The heat dissipation plate is located on the circulating water inlet pipe.

[0011] By adopting the above technical solution, under the action of the circulating water pump, the heated water in the rotating tube will enter the circulating water inlet pipe through the circulating water outlet pipe connected to the rotating tube. The circulating water inlet pipe will then cool the heated water. A heat dissipation plate is installed on the circulating water inlet pipe, which can further accelerate the cooling effect of the heated water. The cooled water is directly discharged into the circulating water tank through the circulating water inlet pipe. The circulating water inlet pipe continuously injects cooling water into the circulating water tank, which can pressurize the circulating water tank. This allows the cooled water in the circulating water tank to enter the second connecting groove through the gap between the rotating tube and the outlet pipe, thereby realizing the circulation of cooling water.

[0012] Optionally, a first toothed ring is provided on the outer wall of the conveying cylinder, a first drive motor is provided on the mounting bracket, and a first drive gear is provided on the output shaft of the first drive motor, the first drive gear meshing with the first toothed ring.

[0013] By adopting the above technical solution, the first drive motor is started. Since the first drive gear and the first gear ring mesh, the first drive motor can drive the conveying cylinder to rotate, thereby realizing the conveying of lime powder through the conveying cylinder.

[0014] Optionally, a second toothed ring is provided on the outer wall of the water outlet pipe, a second drive motor is provided on the mounting bracket, and a second drive gear is provided on the output shaft of the second drive motor, the second drive gear meshing with the second toothed ring.

[0015] By adopting the above technical solution, the second drive motor is started. Since the second drive gear and the second gear ring mesh, the second drive motor can drive the water outlet pipe to rotate. Therefore, it can drive the first rotating block and the second rotating block to rotate, so that the cooling pipe rotates in the conveying cylinder with the rotating pipe as the rotation center. This allows multiple cooling pipes to contact the lime powder more evenly, thereby improving the cooling effect on the lime powder in the conveying cylinder.

[0016] Optionally, an annular slide rail is coaxially arranged on the side wall of the conveying cylinder, and a pulley is provided on the mounting frame, with the pulley disposed in the annular slide rail.

[0017] By adopting the above technical solution, installing the pulley in the annular slide rail can convert the sliding friction between the conveying cylinder and the mounting frame into rolling friction, thereby facilitating the rotation of the conveying cylinder, reducing the load on the first drive motor, and improving the service life of the first drive motor.

[0018] Optionally, a first bearing is provided between the first rotating block and the conveying cylinder, and a second bearing is provided between the second rotating block and the conveying cylinder.

[0019] By adopting the above technical solution, the first bearing can reduce the friction between the first rotating block and the conveying cylinder, and the second bearing can reduce the friction between the second rotating block and the conveying cylinder, thereby facilitating the rotation of the first and second rotating blocks, reducing the load on the first and second drive motors, and improving the service life of the first and second drive motors.

[0020] Optionally, a rotating plate is provided on the side wall of the cooling pipe, and a dust removal plate is provided at the end of the rotating plate away from the rotating pipe.

[0021] By adopting the above technical solution, the rotating pipe can drive the rotating plate to rotate synchronously when it rotates, thereby stirring the lime powder in the conveying cylinder and accelerating the cooling effect of the lime powder in the conveying cylinder. The shovel plate can shovel up some lime powder and let it fall onto the cooling pipe, thereby increasing the contact area between the lime powder and the cooling pipe and further accelerating the cooling effect of the lime powder.

[0022] Optionally, the circulating water inlet pipe is arranged in a tortuous manner, and the circulating water inlet pipe has multiple layers along the height direction, and the heat dissipation plate has multiple layers corresponding to the number of layers of the circulating water inlet pipe.

[0023] By adopting the above technical solution, the circulating water inlet pipe is arranged in a tortuous manner and has multiple layers, which can increase the heat dissipation length of the circulating water inlet pipe, thereby improving the cooling effect of the heated water in the circulating water inlet pipe. The heat dissipation plate is arranged in multiple layers corresponding to the circulating water inlet pipe, which can further increase the cooling area of ​​the circulating water inlet pipe, thereby further improving the cooling effect of the heated water in the circulating water inlet pipe.

[0024] Optionally, a first sealing element is provided between the circulating water tank and the end of the outlet pipe away from the conveying cylinder, and a second sealing element is provided between the rotating pipe and the circulating outlet pipe.

[0025] By adopting the above technical solution, the first sealing element can improve the sealing performance between the circulating water tank and the outlet pipe, thereby reducing the leakage of the circulating water tank. The second sealing element can improve the sealing performance between the rotating pipe and the circulating outlet pipe, thereby reducing the leakage of heated water into the circulating water tank and increasing the temperature of the water entering the cooling pipe, thereby reducing the cooling effect on the lime powder.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When the conveying cylinder rotates, the spiral fan blades on the inner wall of the rotating cylinder can drive the lime powder from the inlet to the outlet. The cooling structure on the first and second rotating blocks can cool the lime powder during the conveying process, thus facilitating the preservation of the lime powder.

[0028] 2. Start the second drive motor. Since the second drive gear and the second gear ring mesh, the second drive motor can drive the water outlet pipe to rotate. Therefore, it can drive the first rotating block and the second rotating block to rotate, so that the cooling pipe rotates in the conveying cylinder with the rotating pipe as the rotation center. This allows multiple cooling pipes to contact the lime powder more evenly, thereby improving the cooling effect on the lime powder in the conveying cylinder.

[0029] 3. Under the action of the circulating water pump, the heated water in the rotating tube will enter the circulating water inlet pipe through the circulating water outlet pipe connected to the rotating tube. The circulating water inlet pipe will then cool the heated water. A heat dissipation plate is installed on the circulating water inlet pipe, which can further accelerate the cooling effect of the heated water. The cooled water will be discharged directly into the circulating water tank through the circulating water inlet pipe. The circulating water inlet pipe continuously injects cooling water into the circulating water tank, which can pressurize the circulating water tank. This allows the cooled water in the circulating water tank to enter the second connecting groove through the gap between the rotating tube and the outlet pipe, thereby realizing the circulation of cooling water.

[0030] 4. When the cooling pipe rotates, it can drive the rotating plate to rotate synchronously, thereby stirring the lime powder in the conveying cylinder and accelerating the cooling effect of the lime powder in the conveying cylinder. The shovel plate can shovel up some lime powder and let it fall onto the cooling pipe, thereby increasing the contact area between the lime powder and the cooling pipe and further accelerating the cooling effect of the lime powder.

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] This application discloses a lime powder conveying device with a cooling function.

[0038] A lime powder conveying device with cooling function, as described in the reference. Figure 1 and Figure 2 The system includes a mounting frame 1, on which a conveying cylinder 2 is rotatably mounted. A first gear ring 5 is welded to the outer wall of the conveying cylinder 2. A first drive motor 51 is fixedly mounted on the mounting frame 1. A first drive gear 52 is welded to the output shaft of the first drive motor 51 and meshes with the first gear ring 5. A feed inlet 21 is provided above one end of the conveying cylinder 2, and a discharge outlet 22 is provided below the other end of the conveying cylinder 2. A spiral fan blade 23 is coaxially welded to the inner wall of the conveying cylinder 2. A first rotating block 24 is rotatably mounted on the inner wall of one end of the conveying cylinder 2, and a second rotating block 25 is rotatably mounted on the inner wall of the other end of the conveying cylinder 2. A cooling structure 3 is installed between the first rotating block 24 and the second rotating block 25.

[0039] When the first drive motor 51 is started, the first drive gear 52 and the first gear ring 5 mesh, so the first drive motor 51 can drive the conveying cylinder 2 to rotate. When the conveying cylinder 2 rotates, the spiral fan blades 23 provided on the inner wall of the rotating cylinder can drive the lime powder from the feed port 21 to the discharge port 22. The cooling structure 3 provided on the first rotating block 24 and the second rotating block 25 can cool the lime powder during the conveying process, so as to facilitate the preservation of the lime powder.

[0040] In order to achieve cooling of lime powder, refer to Figure 2 and Figure 3In this embodiment, a first connecting groove 241 is opened on the first rotating block 24, and a second connecting groove 251 is opened in the second rotating block 25. The cooling structure 3 includes a rotating pipe 31, a cooling pipe 32, and a water outlet pipe 33. The water outlet pipe 33 is coaxially rotatably installed on the side of the conveying cylinder 2 away from the first rotating block 24. The end of the water outlet pipe 33 that passes through the conveying cylinder 2 is connected to the second connecting groove 251. The water outlet pipe 33 is integrally set with the second rotating block 25. A second toothed ring 6 is welded and installed on the outer wall of the water outlet pipe 33. A second drive motor 61 is fixedly installed on the mounting bracket 1. A second drive gear 62 is welded and installed on the output shaft of the second drive motor 61. The second drive gear 62 meshes with the second toothed ring 6. The rotating pipe 31 is coaxially installed in the conveying cylinder 2. One end of the rotating pipe 31 is welded and installed on the first rotating block 24 and is connected to the first connecting groove 241. The rotating pipe 31 is partially installed in the water outlet pipe 33, and the end of the rotating pipe 31 that is away from the first rotating block 24 extends out of the water outlet pipe 33.

[0041] In this embodiment, six cooling pipes 32 are provided. One end of each cooling pipe 32 is welded to the first rotating block 24 and communicates with the first connecting groove 241. The other end of each cooling pipe 32 is welded to the second rotating block 25 and communicates with the second connecting groove 251. A circulation assembly 4 is provided on the rotating pipe 31 and the water outlet pipe 33. When the second drive motor 61 is started, the second drive gear 62 meshes with the second gear ring 6, so the second drive motor 61 can drive the water outlet pipe 33 to rotate. Therefore, it can drive the first rotating block 24 and the second rotating block 25 to rotate, thereby realizing the rotation of the cooling pipe 32. 31 serves as the rotation center and also rotates within the conveying cylinder 2, allowing multiple cooling pipes 32 to contact the lime powder more evenly, thereby improving the cooling effect on the lime powder within the conveying cylinder 2. The circulation component 4 can transport cooling water through the gap between the rotating pipe 31 and the outlet pipe 33 to the second connecting groove 251, and then transport the cooling water from the second connecting groove 251 to each cooling pipe 32, thereby cooling the lime powder during transportation through the cooling pipes 32. The heated water in the cooling pipes 32 then enters the rotating pipe 31 through the first connecting groove, and the heated water is discharged through the rotating pipe 31.

[0042] The circulation component 4 can cool and recycle the discharged hot water, improving resource utilization. In this embodiment, the rotating pipe 31 and the outlet pipe 33 are plastic pipes. The plastic pipe 31 reduces heat dissipation from the heated water inside the plastic pipe, thereby reducing the temperature rise of the cooled quicklime. The plastic pipe 33 reduces heat transfer between the outside and the cooled water inside the outlet pipe 33, thereby reducing the temperature rise of the cooling water entering the cooling pipe 32. In this embodiment, the cooling pipe 32 is a copper pipe. Copper pipes have good thermal conductivity, which can better transfer the heat from the quicklime to the cooling water in the cooling pipe 32.

[0043] When there is a large amount of lime powder in the conveying cylinder 2, some of the lime powder may remain at the bottom of the conveying cylinder 2 and therefore may not be cooled down. (Refer to...) Figure 2 and Figure 3 Therefore, in this embodiment, a rotating plate 9 is welded along the side wall of the cooling pipe 32, and a shovel plate 91 is welded to the end of the rotating plate 9 away from the rotating pipe 31. When the cooling pipe 32 rotates, it can drive the rotating plate 9 to rotate synchronously, thereby stirring the lime powder in the conveying cylinder 2 and accelerating the cooling effect of the lime powder in the conveying cylinder 2. The shovel plate 91 can shovel up some lime powder and let it fall onto the cooling pipe 32, thereby increasing the contact area between the lime powder and the cooling pipe 32 and further accelerating the cooling effect of the lime powder.

[0044] In this embodiment, five sets of rotating plates 9 are welded at intervals. Each set of rotating plates 9 corresponds to six cooling pipes 32. The six rotating plates 9 in each set are welded symmetrically to the side wall of the cooling pipe 32 with the rotating pipe 31 as the rotation center. In this embodiment, the rotating plates 9 are copper plates, which can further transfer the heat in the lime powder, thereby further improving the cooling effect of the lime powder. Five sets of rotating plates 9 is a preferred embodiment. In other embodiments, the number of sets of rotating plates 9 can be adjusted according to actual needs.

[0045] The friction between the conveying cylinder 2 and the mounting bracket 1 may be significant, resulting in a heavy load on the first drive motor 51 and reducing its service life. Similarly, the friction between the first rotating block 24 and the conveying cylinder 2, and between the second rotating block 25 and the conveying cylinder 2, may be significant, resulting in a heavy load on the second drive motor 61 and reducing its service life. (Refer to...) Figure 1 and Figure 2 Therefore, in this embodiment, an annular slide rail 7 is coaxially welded on the side wall of the conveying cylinder 2, and a pulley 71 is installed on the mounting frame 1. The pulley 71 is set in the annular slide rail 7. A first bearing 8 is welded and installed between the first rotating block 24 and the conveying cylinder 2, and a second bearing 81 is welded and installed between the second rotating block 25 and the conveying cylinder 2.

[0046] Installing pulleys 71 in the annular slide rails 7 can convert the sliding friction between the conveying cylinder 2 and the mounting frame 1 into rolling friction, thereby facilitating the rotation of the conveying cylinder 2, reducing the load on the first drive motor 51, and increasing the service life of the first drive motor 51. The first bearing 8 can reduce the friction between the first rotating block 24 and the conveying cylinder 2, and the second bearing 81 can reduce the friction between the second rotating block 25 and the conveying cylinder 2, thereby facilitating the rotation of the first rotating block 24 and the second rotating block 25, reducing the load on the first drive motor 51 and the second drive motor 61, and increasing the service life of the first drive motor 51 and the second drive motor 61. In this embodiment, there are two annular slide rails 7, which are welded and installed on the side walls near both ends of the conveying cylinder 2, and there are also two pulleys 71. In other embodiments, the number of pulleys 71 and annular slide rails 7 can be adjusted according to actual needs.

[0047] Discharging the heated water would be a waste of water resources, as shown in the following example. Figure 2 and Figure 3 Therefore, the circulation component 4 in this embodiment includes a circulating water pump 41, a circulating water tank 42, a circulating water outlet pipe 43, a circulating water inlet pipe 44, and a heat dissipation plate 45. The circulating water tank 42 is installed at the end of the outlet pipe 33 away from the conveying cylinder 2, and the outlet pipe 33 is rotatably installed on the side wall of the circulating water tank 42 and communicates with the inside of the circulating water tank 42. The end of the rotating pipe 31 away from the first rotating block 24 extends into the circulating water tank 42. The circulating water outlet pipe 43 is rotatably connected to the end of the rotating pipe 31 away from the first rotating block 24. The end of the circulating water outlet pipe 43 away from the rotating pipe 31 passes through the bottom wall of the circulating water tank 42 and is connected to the inlet of the circulating water pump 41. One end of the circulating water inlet pipe 44 is installed on the outlet of the circulating water pump 41, and the other end of the circulating water inlet pipe 44 away from the circulating water pump 41 communicates with the side wall of the circulating water tank 42. The heat dissipation plate 45 is welded and installed on the circulating water inlet pipe 44.

[0048] Under the action of the circulating water pump 41, the heated water in the rotating pipe 31 enters the circulating water inlet pipe 44 through the circulating water outlet pipe 43 connected to the rotating pipe 31. The circulating water inlet pipe 44 then cools the heated water. A heat dissipation plate 45 is installed on the circulating water inlet pipe 44, which can further accelerate the cooling effect of the heated water. The cooled water is directly discharged into the circulating water tank 42 through the circulating water inlet pipe 44. The circulating water inlet pipe 44 continuously injects cooling water into the circulating water tank 42, which can pressurize the circulating water tank 42. This allows the cooled water in the circulating water tank 42 to enter the second connecting groove 251 through the gap between the rotating pipe 31 and the outlet pipe 33, thereby realizing the circulation of cooling water.

[0049] In this embodiment, the circulating water outlet pipe 43 and the rotating pipe 31 are both made of plastic. The fact that the circulating water outlet pipe 43 is made of plastic can reduce the heat transfer between the cooled water in the circulating water tank 42 and the heated water in the circulating water outlet pipe 43, thereby reducing the impact on the temperature rise of the cooled water in the circulating water tank 42. In this embodiment, the circulating water outlet pipe 43 is made of copper and the heat sink 45 is made of copper, which can better cool the heated water.

[0050] To improve the cooling effect on heated water, refer to Figure 2 and Figure 3 In this embodiment, the circulating water inlet pipe 44 is arranged in a tortuous manner, and multiple layers are arranged along the height direction. The heat dissipation plate 45 is arranged in multiple layers corresponding to the number of layers of the circulating water inlet pipe 44. The tortuous arrangement and multiple layers of the circulating water inlet pipe 44 can increase the heat dissipation length of the circulating water inlet pipe 44, thereby improving the cooling effect of the heated water in the circulating water inlet pipe 44. The multiple heat dissipation plates 45 corresponding to the number of layers of the circulating water inlet pipe 44 can further increase the cooling area of ​​the circulating water inlet pipe 44, thereby further improving the cooling effect of the heated water in the circulating water inlet pipe 44.

[0051] Since the circulating water tank 42 and the outlet pipe 33 are rotatably connected, and the rotating pipe 31 and the circulating outlet pipe 43 are also rotatably connected, refer to... Figure 2 and Figure 3 Therefore, leakage may occur. In this embodiment, a first sealing element 421 is provided between the circulating water tank 42 and the end of the outlet pipe 33 away from the conveying cylinder 2, and a second sealing element 431 is provided between the rotating pipe 31 and the circulating outlet pipe 43. The first sealing element 421 can improve the sealing between the circulating water tank 42 and the outlet pipe 33, thereby reducing the leakage of the circulating water tank 42. The second sealing element 431 can improve the sealing between the rotating pipe 31 and the circulating outlet pipe 43, thereby reducing the leakage of heated water into the circulating water tank 42 and increasing the temperature of the water entering the cooling pipe 32, thereby reducing the cooling effect on the lime powder. In this embodiment, the first sealing element 421 and the second sealing element 431 are different types of hydraulic rotary joints. The hydraulic rotary joint is a preferred method in this embodiment. In other embodiments, multiple rubber seals can be used to reduce leakage.

[0052] The implementation principle of a lime powder conveying device with cooling function in this application embodiment is as follows:

[0053] Start the first drive motor 51 and the second drive motor 61 to pour quicklime into the conveying cylinder 2 from the feed port 21. Since the first toothed ring 5 on the conveying cylinder 2 meshes with the first drive gear 52 on the output shaft of the first drive motor 51, the conveying cylinder 2 can be rotated, thereby transporting the quicklime to the discharge port 22 through the spiral fan blades 23 welded on the inner wall of the conveying cylinder 2. Since the second drive gear 62 on the output shaft of the second drive motor 61 meshes with the second toothed ring 6 on the water outlet pipe 33, the water outlet pipe 33, the first rotating block 24, the rotating pipe 31, the cooling pipe 32 and the second rotating block 25 can be rotated synchronously, so that the multiple cooling pipes 32 can contact the lime powder more evenly, thereby improving the cooling effect on the lime powder being transported in the conveying cylinder 2.
