Description

Technical Field

[0001] This utility model relates to the technical field of drying devices for detecting the moisture content of mineral products, and in particular to a drying device for detecting the moisture content of mineral products. Background Technology

[0002] In the moisture testing process for mineral products, the performance of the drying components directly determines the drying effect and testing accuracy. Currently available drying equipment generally suffers from numerous problems with its drying components. Some devices have poorly designed hot air supply structures, preventing the hot air from contacting the mineral products evenly and efficiently. This results in some areas being over-dried while others still contain moisture, severely impacting the drying quality.

[0003] Traditional drying components lack effective control and dispersion mechanisms in their feeding structure, leading to mineral accumulation upon entering the drying zone. This makes it difficult for hot air to penetrate the accumulated minerals, requiring significant manpower and time for feeding and maintenance, thus impacting the overall efficiency of the testing process. Therefore, developing a drying component with optimized hot air supply, precise feeding control, uniform and efficient drying, and energy conservation and environmental friendliness is crucial for improving the performance of drying devices used for mineral product moisture detection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drying device for detecting the moisture content of mineral products. It solves the problem that traditional drying components lack an effective control and dispersion mechanism for the feeding structure, which leads to the accumulation of mineral products when they enter the drying area. This makes it difficult for hot air to penetrate the accumulated mineral products, and requires a lot of manpower and time during feeding and maintenance, thus affecting the overall efficiency of the testing work.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a drying device for detecting the moisture content of mineral products, comprising a receiving base, wherein the receiving base is provided with a connecting mechanism, the connecting mechanism includes a driving component disposed on the left section of the receiving base, a receiving component disposed on the middle section of the receiving base, and a drying component disposed on the right section of the receiving base;

[0006] The drying assembly includes a fixed frame, on the top of which a hot air generator is fixedly installed. The inner output end of the hot air generator is connected to a connecting bend, and one end of the connecting bend is connected to a guide pipe. The top of the guide pipe is connected to a feeding hopper, and one end of the feeding hopper is fixedly installed with a motor. The inner output end of the motor is fixedly connected to a rotating feeding roller.

[0007] A further improvement is that the drive assembly includes a mounting base fixedly installed on the top left side of the receiving base. A drive motor is fixedly installed on one end of the inner side of the mounting base. A rotating shaft is fixedly connected to the outer output end of the drive motor. A drive gear is fixedly connected to the outer wall of the rotating shaft. A meshing gear ring is engaged at the top of the drive gear. A connecting frame plate is fixedly connected to the top left side of the receiving base. An end cover is hinged to the inner wall of the connecting frame plate. A fixed handle is fixedly connected to the outer end of the end cover.

[0008] A further improvement is that the receiving component includes an outer cylinder, a screen barrel is fixedly connected to the inner wall of the outer cylinder, an outer cylinder door is hinged to the outer wall of the middle section of the outer cylinder, a connecting handle is fixedly connected to the outer end of the outer cylinder door, and a fixing baffle is fixedly connected to the inner wall of the screen barrel.

[0009] A further improvement is that the fixing frame is fixedly installed on the outer wall of the right end of the receiving base; before starting the mineral drying operation, the operator needs to check whether each component of the device is in normal working condition, and ensure that the drive component, receiving component and drying component in the connecting mechanism are all firmly connected and without abnormalities; then, the mineral product to be dried is added into the device through the feeding hopper. During the feeding process, the operator can control the feeding speed and amount according to the quantity of mineral product and drying requirements.

[0010] A further improvement is that the meshing toothed ring is fixedly connected to the outer wall of the outer cylinder, and the connecting frame plate and end cap are located at the left end of the outer cylinder and the screen barrel; the drive motor starts working after being powered on, and its outer output end will drive the fixedly connected rotating shaft to rotate. During the rotation of the rotating shaft, it will drive the drive gear fixedly connected to its outer wall to rotate synchronously.

[0011] A further improvement is that the screen barrel has screen holes at equal intervals around its circumference, and the fixed baffle is circumferentially set on the inner wall of the screen barrel; the hot air continuously generated by the hot air generator will continuously enter the screen barrel through the connecting bend pipe and the guide pipe, and fully contact the mineral products that are constantly turning inside the screen barrel; the high temperature hot air can quickly absorb the moisture inside the mineral products, causing the moisture to evaporate into water vapor.

[0012] A further improvement is that the inner outer wall of the guide pipe is rotatably connected to the inner wall of the outer cylinder and the screen barrel, and the rotating feeding roller is rotatably connected to the inner wall of the feeding hopper; since the connecting bend has a certain bending angle and length, it can effectively guide the flow of hot air, allowing the hot air to smoothly enter the guide pipe connected to its inner end; when the hot air enters the guide pipe, it will initially contact the mineral products that enter the guide pipe at the same time, and during the process of the mineral products moving towards the receiving component, it will preheat and perform preliminary drying treatment to remove some of the moisture on the surface of the mineral products, laying the foundation for subsequent deep drying.

[0013] By means of the above technical solution, this utility model provides a drying device for detecting the moisture content of mineral products, which has at least the following beneficial effects:

[0014] 1. This utility model uses a drive component to rotate the outer cylinder and the screen barrel, which, together with the fixed baffles on the inner wall of the screen barrel, turns the mineral products over, allowing the mineral products to be fully dispersed. The hot air generated by the hot air generator in the drying component continuously enters the screen barrel through the connecting bend and the guide pipe, making full contact with the constantly turning mineral products. This avoids the problem of uneven heating caused by the accumulation of mineral products, greatly improves the drying efficiency and drying quality, and provides an accurate sample basis for subsequent moisture detection of mineral products.

[0015] 2. When feeding material, the motor drives the rotating feeding roller to evenly feed the material, avoiding feeding blockage. After drying, the mineral product can be easily removed through the outer cylinder door and connecting handle. The end cover and fixed handle facilitate the maintenance and protection of the device. The reasonable design of each component makes the entire drying process simple to operate, reduces manual intervention, reduces the workload of operators, and ensures the smoothness of the entire process from feeding, drying to discharging, thereby improving the overall efficiency of mineral product moisture detection.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Traditional drying components lack effective control and dispersion mechanisms in their feeding structures, leading to mineral accumulation upon entering the drying zone. This makes it difficult for hot air to penetrate the accumulated minerals, requiring significant manpower and time for feeding and maintenance, thus impacting overall testing efficiency. This embodiment provides a drying device for mineral product moisture detection; please refer to... Figures 1-5 An embodiment provides a drying device for detecting the moisture content of mineral products, including a receiving base 1, a connecting mechanism 2, a driving component 21 disposed on the left side of the receiving base 1, a receiving component 22 disposed on the middle side of the receiving base 1, and a drying component 23 disposed on the right side of the receiving base 1; the drying component 23 includes a fixing frame 231, a hot air generator 232 fixedly mounted on the top of the fixing frame 231, a connecting bend 233 connected to the inner output end of the hot air generator 232, a guide pipe 234 connected to one inner end of the connecting bend 233, a feeding hopper 235 connected to the top of the guide pipe 234, a motor 236 fixedly mounted on one front end of the feeding hopper 235, and a rotating feeding roller 237 fixedly connected to the inner output end of the motor 236.

[0026] In this embodiment, before starting the mineral drying operation, the operator needs to check whether each component of the device is in normal working condition, ensuring that the drive component 21, receiving component 22, and drying component 23 in the connecting mechanism 2 are all securely connected and without abnormalities. Then, the mineral to be dried is added to the device through the feeding hopper 235. During the feeding process, the operator can control the feeding speed and amount according to the quantity of the mineral and the drying requirements. The motor 236, fixedly installed at one end of the front of the feeding hopper 235, is started. After the power is turned on, the motor 236 begins to run, and its inner output end drives the fixedly connected rotating feeding roller 237 to rotate synchronously. The rotation of the rotating feeding roller 237 effectively and evenly distributes the mineral in the feeding hopper 235, gradually and smoothly guiding the accumulated mineral into the guide pipe 234, ensuring that the mineral enters the guide pipe 234 stably and evenly, avoiding uneven distribution due to [unclear text - likely a continuation of the previous sentence]. The feeding blockage caused by the large accumulation of mineral products is prevented, ensuring smooth feeding. Simultaneously with starting the motor 236, the hot air generator 232, fixedly installed on the top of the mounting frame 231 in the drying assembly 23, is activated. During operation, the hot air generator 232 heats the air to a set temperature using its internal heating element, generating high-temperature hot air. The generated hot air is transmitted through a connecting bend 233 connected to the inner output end of the hot air generator 232. Due to the bend angle and length of the connecting bend 233, the flow of hot air is effectively guided, allowing it to smoothly enter the guide pipe 234 connected to its inner end. Upon entering the guide pipe 234, the hot air makes initial contact with the mineral products that simultaneously enter the guide pipe 234. As the mineral products move towards the receiving assembly 22, they undergo preheating and preliminary drying, removing some surface moisture and laying the foundation for subsequent deep drying.

[0027] Furthermore, the fixing frame 231 is fixedly installed on the outer wall of the right end of the receiving base 1; the inner outer wall of the guide pipe 234 is rotatably connected to the inner wall of the outer cylinder 221 and the screen barrel 222, and the rotating feeding roller 237 is rotatably connected to the inner wall of the feeding hopper 235.

[0028] Furthermore, the rotation of the feeding roller 237 can effectively and evenly distribute the mineral products in the feeding hopper 235, gradually and smoothly guiding the mineral products accumulated in the feeding hopper 235 into the guide pipe 234, so that the mineral products can enter the guide pipe 234 stably and evenly, avoiding the feeding blockage caused by the large accumulation of mineral products, and ensuring the smoothness of feeding; at the same time as starting the motor 236, the hot air generator 232 fixedly installed on the top of the fixed frame 231 in the drying component 23 is started. Example

[0029] Based on embodiment 1, the drive assembly 21 includes a mounting base 211 fixedly installed on the top left side of the receiving base 1. A drive motor 212 is fixedly installed on one end of the inner side of the mounting base 211. A rotating shaft 213 is fixedly connected to the outer output end of the drive motor 212. A drive gear 214 is fixedly connected to the outer wall of the rotating shaft 213. A meshing gear ring 215 meshes with the top of the drive gear 214. A connecting frame plate 216 is fixedly connected to the top left side of the receiving base 1. An end cover 217 is hinged to the inner wall of the connecting frame plate 216. A fixed handle 218 is fixedly connected to the outer end of the end cover 217. The receiving assembly 22 includes an outer cylinder 221. A screen barrel 222 is fixedly connected to the inner wall of the outer cylinder 221. An outer cylinder door 223 is hinged to the outer wall of the middle section of the outer cylinder 221. A connecting handle 224 is fixedly connected to the outer end of the outer cylinder door 223. A fixed baffle 225 is fixedly connected to the inner wall of the screen barrel 222.

[0030] In this embodiment, after the mineral product undergoes preliminary preheating and drying in the feed pipe 234, it continues to move downwards and finally enters the screen barrel 222 of the receiving component 22. At this time, the drive motor 212, which is fixedly installed on one end of the mounting base 211 in the drive component 21, is started. After being powered on, the drive motor 212 starts to work, and its outer output end drives the fixedly connected rotating shaft 213 to rotate. During the rotation of the rotating shaft 213, it drives the drive gear 214 fixedly connected to its outer wall to rotate synchronously. Since the top of the drive gear 214 meshes with the meshing gear ring 215, and the meshing gear ring 215 is fixedly connected to the outer wall of the outer cylinder 221, the rotation of the drive gear 214 will drive the meshing gear ring 215 to rotate, thereby causing the outer cylinder 221 and its inner wall to rotate. The screen barrel 222 rotates along with the screen barrel 222; during the rotation, the fixed baffles 225 fixedly connected to its inner wall continuously agitate the mineral products inside the screen barrel 222; the fixed baffles 225 effectively break the accumulation of mineral products, continuously lifting and lowering them, allowing the mineral products to be fully and evenly dispersed within the screen barrel 222, increasing the contact area between the mineral products and the hot air; simultaneously, the hot air continuously generated by the hot air generator 232 continuously enters the screen barrel 222 through the connecting bend 233 and the guide pipe 234, fully contacting the constantly agitated mineral products within the screen barrel 222; the high-temperature hot air can quickly absorb the moisture inside the mineral products, causing the moisture to evaporate into water vapor; after drying... During the drying process, because the screen barrel 222 has equidistant circumferentially spaced screen holes, the water vapor evaporated from the mineral products can enter the gap between the outer cylinder 221 and the screen barrel 222 through these screen holes, and then gradually diffuse to the outside of the device, ensuring the dryness of the drying environment and facilitating further drying of the mineral products. Throughout the drying process, the continuous rotation of the outer cylinder 221 and the screen barrel 222, the flipping action of the fixed baffle 225, and the continuous supply of hot air work together to ensure that the mineral products receive comprehensive, uniform, and efficient drying treatment within the screen barrel 222, ensuring that the moisture in the mineral products is fully removed. After the mineral products are dried, the drive motor 212, hot air generator 232, and motor 236, and other power components are first turned off, and the device is allowed to stop operating. Afterwards, the operator can easily open the outer cylinder door 223, which is hinged to the outer wall of the middle section of the outer cylinder 221, with the assistance of the connecting handle 224 fixedly connected to its outer end, and take out the dried mineral product from the screen barrel 222 for subsequent moisture testing. The end cover 217, which is hinged to the inner wall of the connecting frame plate 216 fixedly connected to the top left of the base 1, can be closed when the device is not in use or when internal maintenance or cleaning is required. The operator can easily operate the opening and closing of the end cover 217 through the fixed handle 218 fixedly connected to the outer end of the end cover 217. The end cover 217 plays a role in protecting the internal components of the device and preventing external dust, impurities, etc. from entering the device and affecting the normal operation and service life of the components.The mounting bracket 231 in the drying assembly 23 provides stable and secure support for components such as the hot air generator 232, ensuring the stability of the hot air generator 232 during operation and preventing equipment vibration from affecting the normal supply of hot air and the drying effect.

[0031] Furthermore, the meshing toothed ring 215 is fixedly connected to the outer wall of the outer cylinder 221, and the connecting frame plate 216 and the end cap 217 are provided at the left end of the outer cylinder 221 and the screen barrel 222; the screen barrel 222 is provided with screen holes at equal intervals around its circumference, and the fixing baffle 225 is provided around the inner wall of the screen barrel 222.

[0032] Furthermore, throughout the drying process, the continuous rotation of the outer cylinder 221 and the screen barrel 222, the flipping action of the fixed baffle 225, and the continuous supply of hot air work together to ensure that the mineral products are thoroughly, evenly, and efficiently dried within the screen barrel 222, guaranteeing that the moisture in the mineral products is fully removed. After the mineral products are dried, the drive motor 212, hot air generator 232, and motor 236, and other power components are first turned off, and the device is allowed to stop operating. Then, the operator can easily open the outer cylinder door 223, which is hinged to the outer wall of the middle section of the outer cylinder 221, with the assistance of the connecting handle 224 fixedly connected to its outer end, and remove the dried mineral products from the screen barrel 222 for subsequent moisture testing.

[0033] Working Principle: Before starting the mineral drying operation, the operator needs to check whether all components of the device are in normal working condition, ensuring that the drive component 21, receiving component 22, and drying component 23 in the connecting mechanism 2 are all securely connected and without abnormalities. Then, the mineral to be dried is added to the device through the feeding hopper 235. During the feeding process, the operator can control the feeding speed and amount according to the quantity of the mineral and the drying requirements. The motor 236, fixedly installed at one end of the front of the feeding hopper 235, is started. After the power is turned on, the motor 236 starts running, and its inner output end drives the fixedly connected rotating feeding roller 237 to rotate synchronously. The rotation of the rotating feeding roller 237 effectively and evenly distributes the mineral in the feeding hopper 235, gradually and smoothly guiding the mineral accumulated in the feeding hopper 235 into the guide pipe 234, ensuring that the mineral enters the guide pipe 234 stably and evenly, avoiding uneven distribution due to mineral accumulation. To address the issue of material blockage caused by excessive product accumulation, the system ensures smooth feeding. Simultaneously with starting the motor 236, the hot air generator 232, fixedly mounted on the top of the frame 231 in the drying assembly 23, is activated. During operation, the hot air generator 232 heats the air to a set temperature using its internal heating element, generating high-temperature hot air. This hot air is transmitted through a connecting bend 233 connected to the inner output end of the hot air generator 232. Due to the bend's angle and length, it effectively guides the flow of hot air, allowing it to smoothly enter the guide pipe 234 connected to its inner end. Upon entering the guide pipe 234, the hot air makes initial contact with the mineral products simultaneously entering the guide pipe 234. As the mineral products move towards the receiving assembly 22, they undergo preheating and initial drying, removing some surface moisture and laying the foundation for subsequent deep drying.

[0034] After initial preheating and drying in the feed pipe 234, the mineral product continues to move downwards and finally enters the screen barrel 222 of the receiving component 22. At this time, the drive motor 212, which is fixedly installed on one end of the mounting base 211 in the drive component 21, is started. After being powered on, the drive motor 212 starts to work, and its outer output end drives the fixedly connected rotating shaft 213 to rotate. During the rotation of the rotating shaft 213, it drives the drive gear 214 fixedly connected to its outer wall to rotate synchronously. Because the top of the drive gear 214 meshes with the teeth... The meshing ring 215 is engaged with the outer cylinder 221, and the meshing gear ring 215 is fixedly connected to the outer wall of the outer cylinder 221. Therefore, the rotation of the drive gear 214 will drive the meshing gear ring 215 to rotate, thereby causing the outer cylinder 221 and the screen barrel 222 fixedly connected to its inner wall to rotate together. During the rotation of the screen barrel 222, the fixed baffle 225 fixedly connected to its inner wall will continuously turn over the mineral products inside the screen barrel 222 as the screen barrel 222 rotates. The setting of the fixed baffle 225 can effectively break the accumulation state of the mineral products and continuously turn over the mineral products. The screen rises and falls, allowing the mineral products to be fully and evenly dispersed within the screen barrel 222, increasing the contact area between the mineral products and the hot air. Simultaneously, the hot air continuously generated by the hot air generator 232 enters the screen barrel 222 through the connecting bend 233 and the guide pipe 234, ensuring full contact with the constantly tumbling mineral products within the screen barrel 222. The high-temperature hot air quickly absorbs the moisture inside the mineral products, causing it to evaporate into water vapor. During the drying process, because the screen barrel 222 has equidistant circumferentially spaced screen holes, the mineral products... The water vapor evaporated from the screen can enter the gap between the outer cylinder 221 and the screen barrel 222 through these screen holes, and then gradually diffuse to the outside of the device, ensuring the dryness of the drying environment and facilitating further drying of the mineral products. During the entire drying process, the continuous rotation of the outer cylinder 221 and the screen barrel 222, the flipping action of the fixed baffle 225, and the continuous supply of hot air work together to ensure that the mineral products can be thoroughly, uniformly, and efficiently dried in the screen barrel 222, ensuring that the moisture in the mineral products is fully removed.

[0035] After the mineral products are dried, first turn off all power components such as drive motor 212, hot air generator 232, and motor 236, and wait for the device to stop operating. Then, the operator can easily open the outer cylinder door 223, which is hinged to the outer wall of the middle section of the outer cylinder 221, with the assistance of the connecting handle 224 fixedly connected to its outer end, and take out the dried mineral products from the screen barrel 222 for subsequent moisture testing. The end cover 217, which is hinged to the inner wall of the connecting frame plate 216 fixedly connected to the top left of the base 1, can be used when the device is not in use or when internal maintenance is required. When maintaining or cleaning, the end cover 217 is closed. The fixed handle 218 is fixedly connected to the outer end of the end cover 217, allowing the operator to easily operate the end cover 217. The end cover 217 serves to protect the internal components of the device, preventing external dust, impurities, etc. from entering the device and affecting the normal operation and service life of the components. The fixing frame 231 in the drying component 23 provides stable and firm installation support for components such as the hot air generator 232, ensuring the stability of the hot air generator 232 during operation and avoiding the impact of equipment vibration on the normal supply of hot air and the drying effect.
