Description

Technical Field

[0001] This utility model belongs to the field of low-temperature material drying technology. Specifically, it relates to a low-temperature drying machine for slag materials that can effectively solve the problem that current low-temperature drying machines cannot be applied in the field of drying slag materials. It has a reasonable and compact structure, regular material distribution, adjustable material distribution thickness, and can effectively ensure the drying effect of slag materials. Background Technology

[0002] A low-temperature sludge dryer is a device that uses low-temperature hot air to dry materials. It is widely used in the drying of various types of sludge in municipal, chemical, electroplating, printing and dyeing, papermaking, and leather industries. The material distributor in a low-temperature sludge dryer is a key component in the process. It is primarily responsible for evenly distributing the sludge to be treated within the drying equipment to ensure uniform heating and effective drying. The material distributor plays a crucial role in the low-temperature drying process, directly impacting the drying efficiency and effectiveness of the sludge.

[0003] Chinese patent application CN213955941U, authorized announcement date August 13, 2021, entitled "A Fabric Cutting Device for a Rotary Discharge Dryer," discloses a traditional fabric feeding machine structure used in conjunction with a low-temperature dryer. The structure mainly includes a motor, a cutting roller, a first transmission roller, and a drive wheel. The cutting roller and the first transmission roller are arranged radially at the wet material inlet of the dryer. The output shaft of the motor is connected to the drive wheel, and the drive wheel is connected to the first transmission roller via a chain. The first transmission roller drives the cutting roller. The slitting roller and the first drive roller are arranged above the material tray along the radius of the tray. The output shaft of the motor is connected to a drive wheel, which is connected to both the first and second drive rollers via a chain, causing them to rotate synchronously. Outwardly opening blades are installed on the rotating shafts of the stirring roller and the second drive roller. From the outer circumference to the inner circumference of the material tray, the number of blades decreases from dense to sparse, with more blades on the outside and fewer on the inside. The second drive roller drives the stirring roller to rotate synchronously, uniformly mixing the sludge input from the wet material inlet before pushing it to the first drive roller and the slitting roller. Therefore, it can be seen that traditional low-temperature belt dryers use a slitting machine feeding method to cut the sludge into strips and evenly spread them on the mesh belt for drying. However, with the increasing demand for drying, materials such as medicinal residue and biogas residue, which cannot be processed by the slitting machine, also need to be dried. How to evenly spread these materials on the mesh belt of the dryer, which cannot be cut into strips, has become an urgent technical problem to be solved. Utility Model Content

[0026] Example 1

[0027] like Figure 1 As shown, this embodiment discloses a material distribution machine for a low-temperature drying machine, including a material leveling mechanism 1 and a material distribution mechanism 2 disposed below the material leveling mechanism 1. The material leveling mechanism 1 includes a material leveling bin 11 with an open top and a discharge port 111 at the bottom. A material leveling device 12 driven by a material leveling power unit 13 is horizontally disposed inside the material leveling bin 11. The material distribution mechanism 2 includes a material distribution bin 21 with its top connected to the discharge port 111. A material distribution device 22 driven by a material distribution power unit 23 is horizontally disposed inside the material distribution bin 21. A discharge port 211 is located at the bottom of the material distribution bin 21, and the material falling from the discharge port 211 is transported by a material conveying device. The bottom of the material distribution bin 21 is open, which is the discharge port 211.

[0028] In this embodiment, the material leveling mechanism 1 and the material distribution mechanism 2 are arranged in an upper and lower structure. The slag-like material enters from the top opening of the leveling silo 11. The leveling power unit 13 drives the leveler 12 to spread the accumulated material as evenly as possible within the leveling silo 11, thereby ensuring that the material entering the distribution silo 21 from the discharge port 111 can be evenly distributed. The distribution silo 21 is designed with a distributor 22. The material entering from the discharge port 111 fills the distributor 22. The distribution power unit 23 drives the distributor 22 to rotate. The rotation of the distributor 22 causes the material to be evenly and quantitatively discharged from the discharge port 211. The material naturally falls onto the material conveying device and is transported by the material conveying device.

[0029] This embodiment effectively solves the problem that current low-temperature dryers cannot be applied to the drying of slag-like materials. This invention uses a purely physical method for material distribution, which does not alter the original properties of the material. The distribution is uniform and regular, providing a strong foundation for the excellent drying effect of low-temperature dryers on slag-like materials. This invention greatly expands the application fields of low-temperature dryers.

[0030] In this embodiment, the fabric thickness is adjustable, further ensuring the drying effect of slag-like materials.

[0031] This embodiment has a reasonable and compact structural design and is highly practical, filling the technological gap in the field of low-temperature dryers for processing slag-like materials.

[0032] Example 2

[0033] Based on Embodiment 1, this embodiment continues to describe in detail the technical features involved therein and the functions and roles of these technical features in this utility model, so as to help those skilled in the art to fully understand the technical solution of this utility model and reproduce it.

[0034] like Figures 1-3 As shown, this embodiment discloses a material distribution machine for a low-temperature drying machine, including a material distribution mechanism 1 and a material distribution mechanism 2 disposed below the material distribution mechanism 1. The material distribution mechanism 1 includes a material distribution bin 11 with an open top and a discharge port 111 at the bottom. The bottom cross-section of the material distribution bin 11 is arc-shaped, which facilitates material discharge and eliminates dead corners. Inside the material distribution bin 11, a material distribution device 12 driven by a material distribution power unit 13 is arranged laterally. Specifically, the material distribution device 12 includes a material distribution shaft 121 and spiral blades fixed on the material distribution shaft 121; the spiral blades are two oppositely arranged forward spiral blades 122 and reverse spiral blades 123. The material distribution power unit 13 is a material distribution reducer, which drives the material distribution shaft 121 to rotate. Since the material entering from the discharge port 111 usually accumulates in the middle, the forward spiral blade 122 and the reverse spiral blade 123 simultaneously convey the material to both ends, spreading the material as evenly as possible in the equalization bin 11, thereby effectively ensuring that the material falling from the discharge port 111 can evenly cover the distributor 22.

[0035] The material distribution mechanism 2 includes a material distribution bin 21 connected at the top to the discharge port 111. Inside the material distribution bin 21, a material distributor 22 driven by a material distribution power unit 23 is arranged laterally. A discharge port 211 is located at the bottom of the material distribution bin 21, and materials falling from the discharge port 211 are transported by a material conveying device. Specifically, the material distributor 22 includes a material distribution shaft 221 and multiple material distribution plates 222 arranged laterally. The multiple material distribution plates 222 are fixedly connected to the material distribution shaft 221 and are regularly spaced along the circumferential direction of the material distribution shaft 221. The material distribution power unit 23 is a material distribution reducer, which drives the material distribution shaft 221 to rotate. The area between adjacent material distribution plates 222 is a region for carrying slag-like materials, and the size of this region is equal. Therefore, the rotation of the material distributor 22 enables the material to be uniformly and quantitatively discharged from the discharge port 211.

[0036] In this embodiment, the material conveying device is a belt conveyor, such as a belt conveyor or a mesh belt conveyor. The belt conveyor includes a conveyor belt 41 for receiving falling materials and conveying them towards the feed inlet of the low-temperature dryer. A gate 24 is fixedly installed on the material hopper 21. The gate 24 is used to regulate the material moving with the conveyor belt 41. The height difference h between the end of the gate 24 and the conveyor belt 41 is the material discharge thickness. The gate 24 plays a role in regulating and leveling, ensuring that the thickness of the material entering the low-temperature dryer is uniform and consistent, effectively guaranteeing the drying effect of the material. Figure 3 In the diagram, the dashed arrows represent the feeding direction of slag-like materials, while the solid arrows represent the conveyor belt and the direction of movement of the materials on the conveyor belt.

[0037] In this embodiment, the gate 24 is fixedly connected to the material feeding bin 21 in a height-adjustable manner. That is, the height of the gate 24 is adjustable, allowing control over the specific material discharge thickness as needed. The higher the gate 24 is adjusted, the larger the value of h; conversely, the lower the gate 24 is adjusted, the smaller the value of h. There are many ways to achieve height adjustment, which are existing technologies and will not be elaborated upon here to avoid unnecessary detail.

[0038] In this embodiment, the material leveling power unit 13 and the material distribution power unit 23 are both fixedly supported on the frame 3, and the frame 3 is fixedly connected to the material leveling bin 11 and the material distribution bin 21.

[0039] This embodiment effectively solves the problem that current low-temperature dryers cannot be applied to the drying of slag-like materials. This invention uses a purely physical method for material distribution, which does not alter the original properties of the material. The distribution is uniform and regular, providing a strong foundation for the excellent drying effect of low-temperature dryers on slag-like materials. This invention greatly expands the application fields of low-temperature dryers.

[0040] In this embodiment, the fabric thickness is adjustable, further ensuring the drying effect of slag-like materials.

[0041] This embodiment has a reasonable and compact structural design and is highly practical, filling the technological gap in the field of low-temperature dryers for processing slag-like materials.

[0042] In summary, this is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent variations and modifications made in accordance with the shape, structure, features and spirit of the claims of the present utility model should be included within the scope of the claims of the present utility model.
