Description

Technical Field

[0001] This utility model relates to the field of building material production technology, and in particular to a multi-layer belt drying device for silica fume gel materials. Background Technology

[0002] Silica gel material is a material with silica as its main component, prepared through various processes and precursors. Wollastonite is a very fine silica powder, a byproduct of the production of ferrosilicon alloys or silicon metal. Silica gel is a porous solid material prepared from wollastonite through chemical methods. In the production process of silica gel material, multi-layer belt drying equipment is usually required for drying. By extending the drying path, the drying effect is achieved. Existing multi-layer belt drying equipment uses multiple power sources to drive the conveyor belt to transport materials. The repetition of power sources leads to energy waste. At the same time, because the position of the warm air inlet is fixed, the distance between the material and the warm air inlet may vary, resulting in inconsistent drying degree of the material and limiting the drying effect.

[0003] To address the aforementioned issues, a multi-layer belt drying device for silica fume gel materials has been developed. Utility Model Content

[0004] To overcome the shortcomings of existing multi-layer belt dryers that use multiple power sources to drive the conveyor belt to transport materials, resulting in energy waste due to repeated power source use, and inconsistent drying degree and limited drying effect due to the fixed position of the warm air inlet and the possible difference in distance between the material and the warm air inlet, this utility model provides a multi-layer belt dryer for silica fume gel materials.

[0005] The technical implementation scheme of this utility model is as follows:

[0006] A multi-layer belt drying device for silica fume gel materials includes a first mounting frame, a first driving assembly mounted on the first mounting frame, a conveyor belt fitted on the first driving assembly, an oven placed on the left side of the first mounting frame, warm air vents on the upper sides of both the left and right sides of the oven, connecting rods connected to the front and rear sides of both the left and right sides of the oven, a second mounting frame placed on the left side of the oven, a second driving assembly connected between the oven and the first mounting frame, the second driving assembly located at the upper part of the oven, a third driving assembly mounted in the middle of the oven, a fourth driving assembly mounted between the lower part of the oven and the second mounting frame, two transmission assemblies mounted between the second and third driving assemblies, and two transmission assemblies also mounted between the fourth and third driving assemblies, with every four adjacent transmission assemblies forming a group, and a material transfer mechanism provided between each group of adjacent transmission assemblies.

[0007] Furthermore, the material transfer mechanism includes a first discharge plate, which is connected between the front and rear sides of the upper left part of the oven and between the front and rear sides of the lower right part of the oven. A second discharge plate is rotatably connected to the outer side of the first discharge plate. Torsion springs are connected between the front and rear sides of the second discharge plate and the adjacent first discharge plate. A first limiting plate that limits the movement of the adjacent second discharge plate is connected to the front and rear sides of the first discharge plate. A feeding component is connected to the outer side of each transmission assembly. The feeding component has several inclined surface structures. A second limiting plate is connected to the upper side of the second discharge plate. A third limiting plate is also connected to the upper side of the discharge plate.

[0008] Furthermore, it also includes an auxiliary air blowing mechanism, which includes a fan. The fan is installed on the front side of the middle part of the oven, and a mounting frame is connected to the inner side of the middle part of the oven. A filter plate for filtering air is connected to the mounting frame.

[0009] Furthermore, the conveyor belt is equipped with several baffles, which can prevent the silica fume material from slipping during the conveying process.

[0010] Furthermore, the lower part of the oven is equipped with a triangular base frame to increase the conveying height difference.

[0011] Furthermore, both the third limiting plate and the adjacent second limiting plate have obtuse angles.

[0012] By adopting the above technical solution, this utility model has the following advantages:

[0013] 1.

This utility model is equipped with a material transfer mechanism, which redistributes the material through the feeding component and the inclined structure, thereby re-mixing the material and making the drying more uniform, which is conducive to improving the drying effect. At the same time, the feeding component and the inclined structure can temporarily store the material, which helps to balance the transportation speed of each conveying component and prevent the material from being blocked during transportation.

[0014] 2. This utility model is equipped with an auxiliary blower mechanism, which uses a fan to blow air into the oven, thereby accelerating the airflow speed inside the oven and thus accelerating the temperature rise of the air inside the oven, which is beneficial to improving the drying efficiency of materials.

Detailed Implementation

[0023] 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 1

[0024] A multi-layer belt drying device for silica fume gel materials, such as Figure 1 and Figure 2As shown, it includes a first mounting frame 1, a first drive assembly 2 mounted on the first mounting frame 1, a conveyor belt 3 sleeved on the first drive assembly 2, and several baffles on the conveyor belt 3 to prevent silica fume material from slipping during the conveying process. An oven 4 is placed on the left side of the first mounting frame 1. The oven 4 has a triangular base frame at the bottom to increase the conveying height difference. The oven 4 has a warm air vent 41 on the upper side of both the left and right sides. The oven 4 has connecting rods 42 connected to the front and rear sides of both the left and right sides. A second mounting frame 8 is placed on the left side of the oven 4. A second drive assembly 5 is connected between the oven 4 and the first mounting frame 1.

[0025] The second drive assembly 5 is located on the upper part of the oven 4. The third drive assembly 7 is installed in the middle of the oven 4. The fourth drive assembly 9 is installed between the lower part of the oven 4 and the second mounting frame 8. Two transmission assemblies 6 are installed between the second drive assembly 5 and the third drive assembly 7. Two transmission assemblies 6 are also installed between the fourth drive assembly 9 and the third drive assembly 7. Every four adjacent transmission assemblies 6 form a group. A material transfer mechanism 10 is provided between the front and rear adjacent transmission assemblies 6 in each group.

[0026] like Figures 1-6 As shown, the material transfer mechanism 10 includes a first discharge plate 101. The first discharge plate 101 is connected between the front and rear sides of the upper left part of the oven 4, and the first discharge plate 101 is also connected between the front and rear sides of the lower right part of the oven 4. The outer sides of the first discharge plate 101 are rotatably connected to a second discharge plate 102. The front and rear sides of the second discharge plate 102 are connected to the adjacent first discharge plate 101 with torsion springs 103. The front and rear sides of the first discharge plate 101 are connected to a first limiting plate 104 that limits the adjacent second discharge plate 102. The outer side of each transmission assembly 6 is connected to a feeding component 105. The feeding component 105 is provided with several inclined surface structures 106. The upper side of the second discharge plate 102 is connected to a second limiting plate 107. The upper side of the discharge plate is also connected to a third limiting plate 108. The third limiting plate 108 and the adjacent second limiting plate 107 are both obtuse angles.

[0027] It should be noted that silica gel material is a material with silica as the main component, prepared through various processes and precursors. Wollastonite is a very fine silica powder, a byproduct of the production of ferrosilicon alloys or silicon metal. Silica gel is a porous solid material prepared by chemical methods using wollastonite. In the production process of silica gel material, a multi-layer belt drying device is usually required for drying. By extending the drying path, the drying effect is achieved. First, the material is placed on the conveyor belt 3, and then the first drive component 2 is started. The first drive component 2 drives the conveyor belt 3 to move, thereby conveying the material to the left until it enters the oven 4. The baffles on the conveyor belt 3 can block the material and prevent it from slipping during transportation.

[0028] As the material is continuously conveyed, when the material is on the second drive assembly 5, the second drive assembly 5 is activated. The second drive assembly 5 drives the material to be continuously conveyed. At the same time, the hot air vent 41 delivers warm air into the oven 4. The material begins to dry when it is on the second drive assembly 5. When the material moves to the left side of the second drive assembly 5, the first discharge plate 101 receives the material. At the same time, the transmission assembly 6 rotates, driving the unloading part 105 to rotate, which in turn drives the adjacent inclined structure 106 to rotate. This causes the inclined structure 106 to squeeze the second discharge plate 102. The second discharge plate 102 rotates downward under force, allowing the material to be transferred to the adjacent inclined structure 106 through the second discharge plate 102. As the inclined structure 106 continues to rotate, the adjacent second discharge plate 102 will repeatedly break away from the squeezed state, and then the second discharge plate 102 will be reset upward under the action of the torsion spring 103.

[0029] To prevent material from splashing and wasting when the second discharge plate 102 resets upwards, the second limiting plate 107 and the third limiting plate 108 block and limit the material. As the feeding component 105 and the inclined structure 106 continue to rotate, the material is conveyed to the third drive component 7. The third drive component 7 conveys the material to the right. When the material moves to the first discharge plate 101 on the right, the above operation is repeated until the material is discharged after passing through the fourth drive component 9. The feeding component 105 and the inclined structure 106 can redistribute the material, thereby mixing the material again, making the drying more uniform and improving the drying effect. Example 2

[0030] Based on Example 1, such as Figure 1 , Figure 2 and Figure 7 As shown, it also includes an auxiliary air blowing mechanism, which includes a fan 111. The fan 111 is installed on the front side of the middle part of the oven 4, and a mounting frame 112 is connected to the inner side of the middle part of the oven 4. A filter plate 113 for filtering air is connected to the mounting frame 112.

[0031] It should be noted that, in order to speed up the drying efficiency, the auxiliary blower mechanism 11 can be used to blow air into the oven 4 using the fan 111, thereby speeding up the air flow inside the oven 4 and thus accelerating the temperature rise of the air inside the oven 4, which is beneficial to improving the drying efficiency of the materials.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
