Description

Technical Field

[0001] This application relates to the field of drying technology, and in particular to a drying device for composite chromium sand powder. Background Technology

[0002] Composite chromium sand powder, as a high-performance industrial raw material, has wide applications in various fields such as refractories, ceramics, coatings, and casting. Its unique physical and chemical properties, such as high hardness, wear resistance, and chemical stability, make it an indispensable key material in these industries. However, the performance and quality of composite chromium sand powder are significantly affected by its humidity level. Excessive humidity may cause the product to agglomerate and clump during storage and transportation, even affecting its subsequent processing and use. Therefore, precise humidity control of composite chromium sand powder is crucial to ensuring its stable quality and performance.

[0003] In the production process of composite chromium sand powder, drying equipment is an important means of achieving humidity control. However, due to the large differences in particle shape, size and density of composite chromium sand powder, traditional drying equipment often fails to guarantee a uniform drying effect, resulting in uneven humidity distribution of the product and thus affecting the overall quality of the product. Therefore, it needs to be improved. Utility Model Content

[0004] To address the problem that traditional drying equipment struggles to guarantee uniform drying results, this application provides a composite chromium sand powder drying device.

[0005] The composite chromium sand powder drying equipment provided in this application adopts the following technical solution:

[0006] A composite chromium sand powder drying device includes a frame, a drying box mounted on the frame, a drying cylinder inside the drying box, the top of the drying cylinder being open, a raw material inlet for feeding material into the drying cylinder on the drying box, a plurality of grading conveyor discs arranged at intervals along the height direction of the drying cylinder inside the drying cylinder, each of the grading conveyor discs having a plurality of powder leakage holes through it, a drying mechanism mounted on the frame, the drying mechanism including a hot air box, a hot air source and a plurality of hot air pipes, the hot air box being connected to the drying box, the hot air source and the plurality of hot air pipes being arranged inside the hot air box, the hot air end of the hot air source being connected to the plurality of hot air pipes, the plurality of hot air pipes corresponding to the plurality of grading conveyor discs respectively, and a stirring mechanism for reducing the accumulation of chromium sand powder on the drying box.

[0007] Because the particle shape, size and density of composite chromium sand powder vary greatly, traditional drying equipment often cannot guarantee a uniform drying effect, resulting in uneven product humidity distribution, which affects the overall quality of the product. By adopting the above technical solution, the frame, drying box and drying mechanism are all installed on the frame, the drying cylinder is located inside the drying box, several graded transfer discs are installed in the drying cylinder in sequence, and the drying mechanism includes a hot air box, a hot air source and several hot air pipes.

[0008] When drying composite chromium silica powder, the powder is precisely fed into the uppermost classifying and conveying disc of the drying cylinder through the raw material inlet. Once the powder enters the uppermost classifying and conveying disc, the stirring mechanism immediately starts, gently and effectively agitating the material to break up any agglomerates and promote uniform distribution on the disc. As stirring continues, the powder begins to gradually move downwards through the powder-filtering holes on the top classifying and conveying disc. During this process, smaller or lighter particles preferentially pass through the holes, while larger particles... Heavier particles will continue to be stirred and dried on the upper layer. As the quartz sand powder is transferred from the top layer to the bottom layer, the drying mechanism also starts to work synchronously. The hot air generated by the hot air source is sent into the hot air box through the hot air pipe and blows air to each layer of graded conveyor discs. The hot air forms a circulation in the drying cylinder, heating and drying the material in all directions. It can accurately act on each layer of material. After the quartz sand powder has been dried for a sufficient time, its humidity will reach the predetermined requirements. Open the discharge port at the bottom of the drying cylinder to collect and store the dried quartz sand powder.

[0009] By setting up a drying drum, a graded conveyor plate, and a drying mechanism, the graded conveyor plate transports and dries the material layer by layer, ensuring that each layer of material receives sufficient hot air. This not only helps to distribute the material evenly but also improves drying efficiency. The graded processing method allows the hot air to act more effectively on each layer of material, reducing drying time and energy consumption, achieving precise control over the material drying process, and greatly improving the overall quality of the product.

[0010] Optionally, the drying cylinder is provided with several support seats for supporting the grading and transfer discs, and the grading and transfer discs are respectively connected to the corresponding support seats.

[0011] By adopting the above technical solution, the support base is installed and fixed inside the drying drum, and the grading conveyor plate is installed on the support base. Through the setting of the support base, the support base provides a stable support platform for the grading conveyor plate, ensuring that the grading conveyor plate can be firmly installed inside the drying drum, reducing material spillage or equipment damage caused by shaking or tilting.

[0012] Optionally, the stirring mechanism includes a transmission rod, a transmission motor, and several stirring plates. The transmission motor is connected to the top of the drying chamber, and the output end of the transmission motor is connected to the end of the transmission rod. The transmission rod is rotatably connected inside the drying cylinder. The transmission rod passes through several graded transmission discs in sequence, and several stirring plates are arranged alternately on the transmission rod, with each stirring plate corresponding to a number of graded transmission discs.

[0013] By adopting the above technical solution, the stirring mechanism includes a transmission rod, a transmission motor, and several stirring plates. When the transmission motor starts, its output end is tightly connected to the end of the transmission rod, providing rotational power to the transmission rod. The transmission rod then begins to rotate inside the drying cylinder, and the stirring plates also move accordingly. During the stirring process, the stirring plates gently but powerfully agitate the composite chromium sand powder, breaking up any agglomerations and accumulations that may form in the material. Through the setting of the stirring mechanism, any agglomerations and accumulations that may form in the material are effectively broken up, ensuring the uniform distribution of the material on the grading and conveying disc, reducing the problem of local overheating or insufficient drying, and improving drying efficiency and product quality. At the same time, the movement of the stirring mechanism causes relative displacement between material particles, forming more gaps and channels, which helps hot air to better penetrate the material layer and improves the utilization rate of hot air.

[0014] Optionally, the transmission rod is provided with a connecting rod for mounting the stirring plate, one end of the connecting rod is connected to the transmission rod, and the other end of the connecting rod is connected to the stirring plate.

[0015] By adopting the above technical solution, the stirring plate is mounted on the transmission rod via a connecting rod; the connecting rod serves as the mounting base for the stirring plate, ensuring the stability and reliability of the stirring plate during rotation.

[0016] Optionally, the bottom of the drying cylinder is provided with a material collection chamber, which extends toward the outside of the drying chamber and is connected to the inside of the drying cylinder.

[0017] By adopting the above technical solution, the collection chamber is installed at the bottom of the drying cylinder. The collection chamber serves to collect the dried material, reducing material waste and scattering, and facilitating material discharge. Operators can easily open the outlet of the collection chamber to discharge the dried composite chromium sand powder from the equipment for subsequent collection, storage, or processing.

[0018] Optionally, the transmission rod is provided with two dispersion plates, both of which are arranged in the material collection chamber and symmetrically arranged on both sides of the transmission rod.

[0019] By adopting the above technical solution, two dispersion plates are symmetrically installed on both sides of the transmission rod. The arrangement of the two dispersion plates can effectively disperse the composite chromium sand powder falling into the collection chamber, which helps to reduce the occurrence of blockage in the collection chamber and improve the material discharge efficiency.

[0020] Optionally, a tripod is provided on the transmission rod, and a support rod for mounting the dispersion plate is provided on the tripod.

[0021] By adopting the above technical solution, the tripod is installed on the transmission rod, and the dispersion plate is installed on the tripod via the support rod. Through the setting of the tripod and the support rod, the tripod, as a stable and load-bearing support structure, can effectively enhance the stability of the transmission rod during rotation. Its triangular design principle provides excellent resistance to deformation and overturning, ensuring that the transmission rod can still maintain stable operation when subjected to stirring force and material weight.

[0022] Optionally, a flange for connection is provided between the drying box and the hot air box, with the two ends of the flange corresponding to the drying box and the hot air box respectively.

[0023] By adopting the above technical solution, the drying box and the hot air box are installed through flanges. With the flange as a commonly used connecting component, it has high strength and stability, which can ensure that the connection between the drying box and the hot air box is firm and reliable, effectively resist external forces, and ensure the normal operation of the equipment.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] By setting up a drying drum, a graded conveyor plate, and a drying mechanism, the graded conveyor plate is used to transport and dry the material layer by layer, ensuring that each layer of material receives sufficient hot air. This not only helps to distribute the material evenly but also improves drying efficiency. The graded treatment method allows the hot air to act more effectively on each layer of material, reducing drying time and energy consumption, achieving precise control over the material drying process, and greatly improving the overall quality of the product.

[0026] By setting up the stirring mechanism, the agglomeration and pile-up of materials that may form are effectively broken, ensuring the uniform distribution of materials on the grading and conveying plate, reducing the problem of local overheating or insufficient drying, improving drying efficiency and product quality. At the same time, the movement of the stirring mechanism causes relative displacement between material particles, forming more gaps and channels, which helps hot air to better penetrate the material layer and improves the utilization rate of hot air.

[0027] By setting up two dispersion plates, the composite chromium sand powder falling into the collection chamber can be effectively dispersed, which helps to reduce the occurrence of blockage in the collection chamber and improve the material discharge efficiency. Attached Figure Description

The grading and transfer plates 4 are equipped with holes for the transmission rod 61 to pass through. The grading and transfer plates 4 do not affect the normal rotation of the transmission rod 61.

[0039] Reference Figure 2 and Figure 4 Several stirring plates 63 are sequentially and spaced on the transmission rod 61. In this embodiment, the number of stirring plates 63 is the same as the number of grading transmission disks 4. Each stirring plate 63 corresponds to a single grading transmission disk 4. A connecting rod 7 is installed between the transmission rod 61 and the single stirring plate 63. The connecting rod 7 serves as the mounting base for the stirring plate 63, ensuring the stability and reliability of the stirring plate 63 during rotation.

By providing hot air, the moisture in the composite chromium sand powder is evaporated, thereby achieving the purpose of drying.

[0044] The implementation principle of the composite chromium sand powder drying equipment in this application embodiment is as follows: When drying the composite chromium sand powder, the composite chromium sand powder is precisely fed into the uppermost grading and conveying plate 4 of the drying cylinder 3 through the raw material inlet 21 on the drying chamber 2. Once the sand powder enters the uppermost grading and conveying plate 4, the stirring mechanism 6 is immediately activated to perform a gentle and effective stirring action on the material, breaking up any possible agglomerations and promoting its uniform distribution on the grading and conveying plate 4. As the stirring continues, the sand powder begins to gradually transfer from the powder leakage hole 41 on the top grading and conveying plate 4 to the lower layers. During this process, smaller or lighter particles are... The powder will pass through the powder leakage hole 41 first, while larger or heavier particles will continue to be stirred and dried on the upper layer. While the Ying sand powder is transferred from the top layer to the bottom layer, the drying mechanism 5 also starts to work synchronously. The hot air generated by the hot air source 52 is sent into the hot air box 51 through the hot air pipe 53 and blows air to each layer of the graded transfer plate 4. The hot air forms a circulation in the drying cylinder 3, heating and drying the material in all directions. It can accurately act on each layer of material. After the Ying sand powder has been dried for a sufficient time, its humidity will reach the predetermined requirements. Open the discharge port at the bottom of the drying cylinder 3 to collect and store the dried Ying sand powder.

[0045] With the setting of drying cylinder 3, graded conveyor plate 4 and drying mechanism 5, the graded conveyor plate 4 is used to transfer and dry the material layer by layer, ensuring that each layer of material can receive sufficient hot air. This not only helps the material to be evenly distributed, but also improves the drying efficiency. The graded treatment method allows the hot air to act more effectively on each layer of material, reducing drying time and energy consumption, achieving precise control of the material drying process, and greatly improving the overall quality of the product.
