[0001] The invention belongs to the technical field of screw conveyors, in particular to a screw conveyor for a rotary kiln. Background Art

[0002] Screw conveyors are mainly used to transport sand, powder, additives, finished materials, etc. of various diameters. Traditional screw conveyors include a drive transmission device, a shell, a screw shaft and blades. The screw shaft rotates to push the material in the spiral shell from the feed port to the discharge port. This conveying structure is simple and efficient and is widely used in industry.

[0003] In order to prevent material jamming and deflection changes in the screw shaft, a certain gap must be left between the spiral blades and the shell. This gap will cause a certain amount of material to always be stored in the screw conveyor. When the screw conveyor needs to switch the conveyed product, the existing screw conveyor cannot open and clean the residual material in the shell, which makes the spiral blades easily affected and aged rapidly.

Driven by the spiral blade, the remaining fine materials on the inner wall of the conveying tube can also be transmitted. At the same time, the arc rod scrapes the spiral blade, so that the material attached to the spiral blade is cleaned to a certain extent, so that the surface of the spiral blade is kept clean and the maintenance time is extended.

[0013] Furthermore, the scraping assembly includes a fixing plate, the outer wall of the fixing plate is fixedly connected to the inner wall of the tube body, six fixing plates are provided, butterfly plates are symmetrically provided on the opposite sides of the fixing plate, the outer wall of the butterfly plate is rotatably connected to the opposite side of the fixing plate, the end of the fixing plate away from the butterfly plate is fixedly connected to a rotating rod, the outer wall of the rotating rod is provided with an airbag, the inner wall of the airbag is sleeved with the outer wall of the rotating rod, the outer wall of the rotating rod is evenly provided with a ring, the inner wall of the ring is sleeved with the outer wall of the rotating rod, the outer wall of the ring is clamped with the inner wall of the airbag, and the end of the ring away from the rotating rod is fixedly connected A scraper is connected, and water holes are evenly opened on the outer wall of the scraper.

The inner wall of the tube body is scraped during the rotation of the tube body to avoid scale adhesion. Since the airbag reduces the space inside the tube body, the water flow can contact the inner wall of the tube body, get closer to the material, and flow out quickly, thereby improving the effect of cooling the material and reducing the amount of water used, thereby reducing the weight of the water inside the tube body, so that the drive motor can operate normally, reduce the load, and maintain long-term stable operation of the equipment.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. Since there is a certain gap between the spiral blades and the shell, the gap will cause a certain amount of material to always be stored in the screw conveyor. When the screw conveyor needs to switch the conveyed product, the existing screw conveyor cannot be opened to clean the residual material in the shell, which makes the spiral blades susceptible to accelerated aging. The present invention arranges a conveying mechanism to fill the cooling component with cold water to cool the material from the inside. The scraping component is arranged inside the cooling component to scrape the inner wall of the cooling component to avoid scale adhesion, and the water inside the cooling component is brought closer to the edge of the cooling component, thereby reducing the water flow inside the cooling component, saving the amount of cooling water, and thereby reducing the weight of the cooling component itself and the load on the driving motor. The extension component cleans the surface of the spiral blade under the drive of the cooling component, and can increase the diameter of the spiral blade when extended, so as to thoroughly transmit the debris inside the conveying pipe, and clean the inner wall of the water delivery rod to keep the inside of the conveying pipe clean.

[0016] 2. The present invention sets a cooling component. Since the shape of the tube body is set to be protruding at both ends and round in the middle, the protruding part can be plugged into the moving rod. The moving rod is provided with a hole matching the position of the water inlet hole. By inputting cold water from the inside of the tube body, the heat of the material can not only be transferred to the surface of the conveying pipe, but also can be transferred by the water flow in the tube body, thereby improving the cooling speed, so that heat can be transferred both inside and outside the material, and the material cooling is more uniform and comprehensive.

[0017] 3. When the material is about to be transported, some fine materials accumulate on the inner wall of the conveying pipe, and the spiral blades cannot transport all the materials cleanly. The present invention sets an extension component to enable the arc rod to move along the surface of the spiral blade, and gradually increase the diameter of the spiral blade in the process of moving outward, so as to contact the inner wall of the conveying pipe. Driven by the spiral blades, the remaining fine materials on the inner wall of the conveying pipe can also be transported. At the same time, the arc rod scrapes the spiral blades, so that the materials attached to the spiral blades are cleaned to a certain extent, so as to keep the surface of the spiral blades clean and extend the maintenance time.

[0018] 4. The present invention provides a scraping assembly, and the scraper is always placed vertically in the tube body. The inner wall of the tube body is scraped during the rotation of the tube body to avoid scale adhesion. Since the airbag reduces the space inside the tube body, the water flow can contact the inner wall of the tube body, get closer to the material, and flow out quickly, thereby improving the effect of cooling the material and reducing the amount of water used, thereby reducing the weight of the water inside the tube body, allowing the drive motor to operate normally, reducing the load, and maintaining long-term stable operation of the equipment.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0029] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a screw conveyor for a rotary kiln is described as follows.

[0030] The base 1 comprises: two bases 1 are symmetrically arranged;

[0031] The rotary kiln screw conveyor also includes:

[0032] The conveying mechanism 2, the outer wall of the conveying mechanism 2 is fixedly connected to the top of the base 1;

[0033] The top of the conveying mechanism 2 is fixedly connected with a feed port 3 , the bottom of the conveying mechanism 2 at one end away from the feed port 3 is fixedly connected with a discharge port 5 , and the outer wall of the conveying mechanism 2 is fixedly connected with a cooling mechanism 4 .

[0034] During operation, workers place the feed port 3 of the screw conveyor at the discharge end of the rotary kiln, so that the material in the rotary kiln can fall into the feed port 3, and then enter the conveying mechanism 2. After being conveyed by the conveying mechanism 2 and cooled by the cooling mechanism 4, the material is cooled inside the conveying mechanism 2 and then reaches the discharge port 5 for discharge. During the conveying process, the conveying mechanism 2 promotes the cooling of the material and assists in discharging all the material. The discharge port 5 is connected to a collection device to carry out the next step of material processing.

[0035] The conveying mechanism 2 includes a conveying pipe 201, the outer wall of the conveying pipe 201 is fixedly connected to the top of the base 1, the inner wall of the conveying pipe 201 is rotatably connected to the cooling component 202, the inner wall of the cooling component 202 is evenly provided with scraping components 206, and the outer wall of the cooling component 202 is evenly provided with extension components 204; the conveying mechanism 2 also includes a spiral blade 203, the end of the spiral blade 203 does not contact the inner wall of the conveying pipe 201, leaving a gap, the inner wall of the spiral blade 203 is fixedly connected to the outer wall of the cooling component 202, the end of the cooling component 202 close to the feeding port is fixedly connected to the water injection port 205, the outer wall of the scraping component 206 is fixedly connected to the inner wall of the cooling component 202, and the outer wall of the extension component 204 is fixedly connected to the outer wall of the cooling component 202.

[0036] When the material is conveyed, the external drive motor drives the cooling component 202 to rotate, thereby driving the spiral blade 203 to rotate, and conveying the material entering the conveying pipe 201 to the lower material port 5. During the conveying process, cold water is injected from the end of the cooling component 202 close to the feed port 3, so that the cooling component 202 is filled with cold water to cool the material from the inside. The scraping component 206 is arranged inside the cooling component 202 to scrape the inner wall of the cooling component 202 to prevent scale adhesion and remove the scale inside the cooling component 202. The water is closer to the edge of the cooling component 202, thereby reducing the water flow inside the cooling component 202, saving the amount of cooling water, and reducing the weight of the cooling component 202 itself, reducing the load of the driving motor, and the extension component 204 is driven by the cooling component 202 to clean the surface of the spiral blade 203. When extended, it can increase the diameter of the spiral blade 203, thoroughly transfer the debris inside the conveying pipe 201, and clean the inner wall of the water delivery rod to keep the inside of the conveying pipe 201 clean.

[0037] The cooling mechanism 4 includes a cover shell 401, the inner wall of the cover shell 401 is fixedly connected to the outer wall of the conveying pipe 201, the inner wall of the cover shell 401 is fixedly connected with a partition 402, the partition 402 is spiral-shaped, the inner wall of the partition 402 is fixedly connected to the outer wall of the conveying pipe 201, a water inlet pipe 404 is symmetrically arranged on one side of the cover shell 401 close to the loading port, the outer wall of the water inlet pipe 404 is fixedly connected to the outer wall of the cover shell 401, and a water outlet pipe 403 is symmetrically arranged on one side of the outer wall of the cover shell 401 close to the unloading port 5, and the outer wall of the water outlet pipe 403 is fixedly connected to the outer wall of the cover shell 401.

[0038] When conveying materials, cold water enters from the water inlet pipe 404, flows along the partition 402 on the surface of the conveying pipe 201, and flows out from the water outlet pipe 403, so that the cold water absorbs the heat on the surface of the conveying pipe during the flow, and the water flow stays in the cover 401 for a longer time under the action of the partition 402, thereby saving water resources.

[0039] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of Example 1, the cooling component 202 includes a tube body 2021, the outer wall of the tube body 2021 is slidably connected to the inner wall of the delivery pipe 201, the outer wall of the tube body 2021 is symmetrically provided with water inlet holes 2022, the inner wall of the tube body 2021 is symmetrically provided with moving rods 2023, the moving rods 2023 are made of a material with good heat conductivity, the outer wall of the moving rod 2023 is slidably connected to the inner wall of the tube body 2021, the end of the moving rod 2023 close to the water injection port 205 is fixedly connected to the extension rod 2024, the end of the extension rod 2024 away from the moving rod 2023 is fixedly connected to the block 2025, and the inner wall of the block 2025 is sleeved with the outer wall of the water injection port 205.

[0040] The shape of the tube body 2021 is set to be protruding at both ends and round in the middle. The protruding part can be inserted into the moving rod 2023. The moving rod 2023 is provided with a hole that matches the position of the water inlet hole 2022. In the process of pushing the block 2025, when the hole of the moving rod 2023 is aligned with the water inlet hole 2022, the water in the tube body 2021 can enter the extension component 204. When the block 2025 moves and separates the hole on the moving rod 2023 from the water inlet hole 2022, the tube body 2021 is in a sealed state, and the driving motor drives the tube body 2021 to rotate, thereby driving the spiral blade 203 to rotate, so that the material is transported. By inputting cold water from the inside of the tube body 2021, the heat of the material can not only be transmitted to the surface of the conveying pipe 201, but also can be transmitted through the water flow in the tube body 2021, thereby improving the cooling speed, so that the heat can be transmitted both inside and outside the material, and the material cooling is more uniform and comprehensive.

[0041] The extension component 204 includes a fixed tube 2041, the outer wall of the fixed tube 2041 is fixedly connected to the outer wall of the tube body 2021, the inner wall of the fixed tube 2041 is provided with a support rod 2042, the fixed tube 2041 and the support rod 2042 are mutually sleeved to form a relatively sealed state, the outer wall of the support rod 2042 is slidably connected to the inner wall of the fixed tube 2041, and the end of the support rod 2042 away from the fixed tube 2041 is fixedly connected with an arc rod 2043, the arc rod 2043 is arc-shaped and made of a friction-resistant material with less friction, and the outer wall of the arc rod 2043 is in contact with the outer wall of the spiral blade 203.

[0042] When the material is about to be transported, some fine materials accumulate on the inner wall of the conveying pipe 201, and the spiral blade 203 cannot transport all the materials cleanly. At this time, the block 2025 drives the moving rod 2023 to align the hole on the moving rod 2023 with the water inlet hole 2022, so that the water in the tube body 2021 is injected into the fixed pipe 2041, and the support rod 2042 is pushed outward under the drive of the water pressure, so that the arc rod 2043 moves along the surface of the spiral blade 203, and gradually increases the diameter of the spiral blade 203 during the outward movement, and contacts the inner wall of the conveying pipe 201. Driven by the spiral blade 203, the remaining fine materials on the inner wall of the conveying pipe 201 can also be transported. At the same time, under the scraping of the arc rod 2043 on the spiral blade 203, the materials attached to the spiral blade 203 are cleaned to a certain extent, so as to keep the surface of the spiral blade 203 clean and extend the maintenance time.

[0043] The scraping assembly 206 includes a fixed plate 2061, the surface of which is provided with a fan-shaped hole corresponding to the butterfly plate 2063, the outer wall of the fixed plate 2061 is fixedly connected to the inner wall of the tube body 2021, and six fixed plates 2061 are provided, two by two in a group, and butterfly plates 2063 are symmetrically provided on the opposite sides of the fixed plate 2061, and the water flow speed in the tube body 2021 is controlled by the angle between the butterfly plate 2063 and the fan-shaped hole, and the outer wall of the butterfly plate 2063 is rotatably connected to the opposite side of the fixed plate 2061, and the end of the fixed plate 2061 away from the butterfly plate 2063 is fixedly connected to the rotating rod 2062, and the outer wall of the rotating rod 2062 is provided with an air bag 2064, and the air bag 2064 wraps the rotating rod 2062, and three air bags 2064 are provided and connected by a connecting pipe 2068, and the inner wall wrapping the rotating rod 2062 is made of a hard material, so that the air bag When 2064 is inflated, its exterior expands, and the expansion size of the airbag 2064 is controlled by the temperature of the material. The inner wall of the airbag 2064 is sleeved with the outer wall of the rotating rod 2062. The outer wall of the rotating rod 2062 is evenly provided with a ring 2065. The inner wall of the ring 2065 is sleeved with the outer wall of the rotating rod 2062. The outer wall of the ring 2065 is snap-fitted with the inner wall of the airbag 2064. The end of the ring 2065 away from the rotating rod 2062 is fixedly connected with a scraper 2066. The scraper 2066 is made of a material that is not easy to rust and has a certain weight. The outer wall of the scraper 2066 is evenly provided with water holes 2067. The water holes 2067 prevent the scraper 2066 from shaking due to the flow of water when the tube body 2021 rotates. The bottom of the scraper 2066 contacts the inner wall of the tube body 2021. The outer wall of the airbag 2064 is fixedly connected with a connecting pipe 2068.

[0044] When the conveying pipe 201 does not enter the material, the fixed plate 2061 closest to the outlet end of the conveying pipe 201 is blocked by the butterfly plate 2063, and the other two groups of butterfly plates 2063 connect the fixed plate 2061, and the air bag 2064 is inflated through the connecting pipe 2068. The diameter of the air bag 2064 after the air injection is determined according to the temperature of the material. After the air injection is completed, the air bag 2064 is kept in an inflated state, and then water is injected into the pipe body 2021 through the water injection port 205. After the inside of the pipe body 2021 is filled with water, when the material is started to be transported, all the butterfly plates 2063 are opened to allow water to flow through the pipe body 2021, absorb the heat on the surface of the pipe body 2021, and then flow out of the conveying pipe 20 1. When conveying materials, the tube body 2021 is in a rotating state, and the collar 2065 rotates along the rotating rod 2062, keeping the scraper 2066 always vertically placed in the tube body 2021. During the rotation of the tube body 2021, the inner wall of the tube body 2021 is scraped to prevent scale adhesion. Since the air bag 2064 reduces the space inside the tube body 2021, the water flow can contact the inner wall of the tube body 2021, get closer to the material, and flow out quickly, thereby improving the effect of cooling the material and reducing the use of cooling water, thereby reducing the weight of the water inside the tube body 2021, so that the drive motor can operate normally, reduce the load, and maintain long-term stable operation of the equipment.

[0045] The specific workflow is as follows:

[0046] During operation, the worker places the feed port 3 of the screw conveyor at the discharge end of the rotary kiln so that the material in the rotary kiln can fall into the feed port 3 and then enter the conveying mechanism 2. When the material is conveyed, the external drive motor drives the cooling component 202 to rotate, thereby driving the spiral blade 203 to rotate and conveying the material entering the conveying pipe 201 to the lower feed port 5. During the conveying process, cold water is injected from the end of the cooling component 202 close to the feed port 3, so that the cooling component 202 is filled with cold water to cool the material from the inside. The scraping component 206 is arranged inside the cooling component 202 to scrape the inner wall of the cooling component 202 to avoid scale adhesion, and to bring the water inside the cooling component 202 closer to the edge of the cooling component 202, thereby reducing the water flow inside the cooling component 202, saving the amount of cooling water, and thereby reducing the weight of the cooling component 202 itself, reducing the load of the drive motor, and lengthening the component. 204 cleans the surface of the spiral blade 203 driven by the cooling component 202. When the spiral blade 203 is extended, its diameter can be increased, the debris inside the conveying pipe 201 is thoroughly transported, and the inner wall of the conveying pipe 201 is cleaned to keep the inside of the conveying pipe 201 clean. When transporting materials, cold water enters from the water inlet pipe 404, flows along the baffle 402 on the surface of the conveying pipe 201, and flows out from the water outlet pipe 403, so that the cold water absorbs the heat on the surface of the conveying pipe 201 during the flow, and prolongs the time the water flow stays inside the cover 401 under the action of the baffle 402. After being transported by the conveying mechanism 2 and cooled by the cooling mechanism 4, the material is cooled inside the conveying mechanism 2 and then reaches the discharge port 5 for discharge. During the conveying process, the conveying mechanism 2 promotes the cooling of the material and assists in discharging all the material. The discharge port 5 is connected to a collecting device to process the material in the next step.
