Description

Technical Field

[0001] This utility model belongs to the field of sulfur granulation technology, specifically a drying device for sulfur granulation. Background Technology

[0002] Industrial sulfur granulation is divided into two methods: dry and wet. In the wet method, liquid sulfur is introduced into a granulator, causing it to form droplets that fall into water, gradually cooling and solidifying into spherical granules. In the dry method, molten sulfur is passed through a granulation device to form granules, which are then cooled and solidified to obtain sulfur granules. Regardless of the granulation method, a drying process is required after granulation to remove surface moisture from the sulfur granules, resulting in a dry, free-flowing finished product. However, during drying, moisture can cause bridging and crystallization between sulfur granules, forming hard lumps and causing agglomeration. Agglomerated sulfur has poor flowability and is not suitable for direct use, thus affecting the quality of the sulfur granules. Therefore, a drying device for sulfur granulation that can disperse sulfur granules and prevent agglomeration during drying is needed. Utility Model Content

[0003] The purpose of this invention is to provide a sulfur granulation drying device that can disperse sulfur particles and prevent sulfur particles from clumping during drying, thereby solving the technical problem that sulfur particles are prone to clumping during drying after granulation, which adversely affects the quality of the dried sulfur granule product.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a drying device for sulfur granulation, including a drying box, an inclined material carrier plate connected inside the drying box, a vibration motor fixedly connected to the bottom of the material carrier plate, both ends of the material carrier plate extending outside the drying box, a plurality of guiding protrusions fixedly connected to the material carrier plate, the guiding protrusions being arranged in pairs, a hot air mechanism fixedly connected below the material carrier plate inside the drying box, a plurality of ventilation holes opened on the material carrier plate above the hot air mechanism, and a dust collection mechanism fixedly connected to the top of the drying box.

[0005] Furthermore, an installation platform is fixedly connected to the inner side wall of the drying chamber, and a spring is fixedly connected to the installation platform. The upper end of the spring is fixedly connected to the bottom of the material carrier plate.

[0006] Furthermore, the hot air mechanism includes a conveying pipe, a hot air duct, and hot air nozzles. The hot air duct is located below the material carrier plate, and at least two hot air ducts are provided. The input ends of the multiple hot air ducts are connected in parallel through the conveying pipe. A hot air generator is fixedly connected to the other end of the conveying pipe. The bottom of the hot air duct is fixedly connected to the bottom of the drying chamber through a support. Several hot air nozzles are fixedly connected to the top of the hot air duct, and the output ends of the hot air nozzles face the bottom of the material carrier plate.

[0007] Furthermore, the dust collection mechanism includes a dust collection pipe, an induced draft fan, and a processing box. An exhaust port is provided on the top of the drying box. One end of the dust collection pipe is fixedly connected to the exhaust port, and the other end is fixedly connected to the input end of the induced draft fan. The output end of the induced draft fan is fixedly connected to the input end of the processing box. Both the processing box and the induced draft fan are fixedly connected to the top of the drying box.

[0008] Furthermore, the processing box is provided with an air inlet, a dust filter layer, an adsorption layer, and an air outlet in sequence from bottom to top, and a maintenance door is hinged to the side wall of the processing box.

[0009] Furthermore, a material conveyor belt is provided below the downward-sloping end of the loading plate.

[0010] This utility model has the following advantages compared with the prior art:

[0011] 1. This utility model uses a carrier plate equipped with a vibrating motor, which is tilted inside a drying oven. Ventilation holes are provided on the carrier plate, and a hot air mechanism is installed below it. Sulfur particles on the carrier plate are dried with hot air. As the sulfur particles move downwards from the carrier plate, the continuously vibrating plate shakes and disperses them, preventing bridging and crystallization between the particles and thus preventing clumping during drying. Pairs of guide strips are installed on the carrier plate to slow the downward movement of the sulfur particles, extending the contact time between the particles and the hot air, thereby ensuring the drying effect and preventing incomplete drying that could negatively impact product quality.

[0012] 2. This utility model, by setting a dust collection mechanism on the top of the drying chamber, has an induced draft fan that continuously draws in the gas inside the drying chamber, sucking in the sulfur dust and irritating gases contained therein and sending them into the treatment chamber. After filtration and adsorption treatment, the gas is then discharged, preventing the surrounding working environment from being polluted by the released sulfur dust and irritating gases, thereby improving the safety of the working environment and reducing the health risks to operators.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figures 1 to 3 The drying device for sulfur granulation shown includes a drying chamber 1. The top of the drying chamber 1 has an exhaust port 4. Holes are provided on both sides of the drying chamber for a material carrier plate 2 to extend out. An inclined material carrier plate 2 is connected inside the drying chamber 1. A vibration motor 3 is fixedly connected to the bottom of the material carrier plate 2. Both ends of the material carrier plate 2 extend outside the drying chamber 1. The upward-inclined end of the material carrier plate 2 serves as the feed end, and the downward-inclined end serves as the discharge end. Several guide strips 5 are fixedly connected to the material carrier plate 2. The guide strips 5 are arranged in pairs and at an incline in three sets. The guide strip 5 serves to block sulfur particles and prolong their residence time on the carrier plate 2. A hot air mechanism is fixedly connected to the drying chamber 1 below the carrier plate 2. The hot air mechanism is used to blow hot air downwards from the carrier plate 2 to dry the sulfur particles on the carrier plate 2. Several ventilation holes 6 are opened on the carrier plate 2 above the hot air mechanism. A dust collection mechanism is fixedly connected to the top of the drying chamber 1. The dust collection mechanism is used to collect and treat the sulfur dust and irritating gases generated in the drying chamber 1 during the drying process.

[0019] In order to place the continuously vibrating material plate 2 driven by the vibration motor 3 inside the drying chamber 1, a mounting platform 7 is fixedly connected to the inner side wall of the drying chamber 1. A spring 8 is fixedly connected to the mounting platform 7 by threads and a locking nut. The upper end of the spring 8 is also fixedly connected to the bottom of the material plate 2 by threads and a locking nut. The spring 8 is used as a consumable part, and the damaged spring 8 is replaced in time during each maintenance and inspection.

[0020] To provide the hot air required for drying sulfur granules, the hot air mechanism includes a conveying pipe 9, a hot air duct 10, and hot air nozzles 11. The hot air duct 10 is located below the material carrier plate 2, and at least two hot air ducts 10 are provided. The input ends of multiple hot air ducts 10 are connected in parallel via the conveying pipe 9. A hot air generator 12 is fixedly connected to the other end of the conveying pipe 9. The bottom of the hot air duct 10 is fixedly connected to the bottom of the drying chamber 1 via a support 13. Several hot air nozzles 11 are fixedly connected to the top of the hot air duct 10, with the output ends of the hot air nozzles 11 facing the bottom of the material carrier plate 2. The hot air generator 12 is a commonly used existing device in the industry, and its structure will not be detailed here. When the hot air generator 12 is working, it provides hot air, which is sent into the hot air duct 10 through the conveying pipe 9 and then blown out through the hot air nozzles 11, directed towards the ventilation holes 6 on the material carrier plate 2.

[0021] To collect and treat sulfur dust and irritating gases inside the drying chamber 1, and to prevent these harmful substances from escaping from the drying chamber 1 and polluting the environment, the dust collection mechanism includes a dust collection pipe 14, an induced draft fan 15, and a treatment chamber 16. One end of the dust collection pipe 14 is fixedly connected to the exhaust port 4, and the other end is fixedly connected to the input end of the induced draft fan 15. The output end of the induced draft fan 15 is fixedly connected to the input end of the treatment chamber 16. Both the treatment chamber 16 and the induced draft fan 15 are fixedly connected to the top of the drying chamber 1. Through continuous suction by the induced draft fan 15, the airflow inside the drying chamber 1, along with the harmful substances, is sent into the treatment chamber 16, where it is treated and then discharged outside the treatment chamber 16.

[0022] To treat the sulfur powder and irritating gases entering the treatment chamber 16, the treatment chamber 16 is equipped with, from bottom to top, an air inlet, a dust filter layer 161, an adsorption layer 162, and an air outlet. The air inlet and outlet are fixedly connected to the treatment chamber 16, while the dust filter layer 161 and adsorption layer 162 are detachably connected to the treatment chamber 16. A maintenance door 163 is hinged to the side wall of the treatment chamber 16. Gas discharged from the induced draft fan 15 enters the treatment chamber 16 through the air inlet, first contacting the dust filter layer 161, where the sulfur powder and a small amount of moisture are blocked and removed. Then, the gas contacts the adsorption layer 162, where the irritating odor components are adsorbed and removed. Finally, the treated gas is discharged from the air outlet. Each time the device is maintained, open the maintenance box door 163, clean the sulfur dust collected under the filter cloth layer 161, replace the filter cloth layer 161 and the adsorption layer 162 with new ones, and close the maintenance box door 163 again to complete the cleaning.

[0023] To facilitate the transfer of dried sulfur granules, a material conveyor belt is installed below the inclined downward end of the carrier plate 2. This conveyor belt allows for quick and convenient transfer of the sulfur granules to the storage location. The material conveyor belt is a commonly used motor-driven conveyor belt in the industry, and is an existing device in this field; its structure will not be described in detail.

[0024] The specific working process of this utility model is as follows:

[0025] The vibrating motor 3, hot air generator 12, and induced draft fan 15 are started, and the device begins to work. The granulated sulfur granules are added to the inclined upward end of the carrying plate 2. The vibrating motor 3 drives the carrying plate 2 to vibrate, shaking the sulfur granules on the carrying plate 2 to prevent them from sticking together. The sulfur granules move continuously downward along the inclined carrying plate 2. The guide strip 5 can slow down the speed at which the sulfur granules move downward on the carrying plate 2, prolonging the contact time between the sulfur granules and the hot air. During this period, the hot air blown out from the hot air nozzle 11 passes through the ventilation hole 6 and sweeps onto the sulfur granules, taking away the moisture and drying them. The hot air carrying moisture is drawn out of the drying chamber 1 from the exhaust port 4 by the induced draft fan 15 and sent to the processing chamber 16 for processing. Finally, the dried sulfur granules are discharged from the lower end of the carrying plate 2 and fall onto the material conveyor belt to be transported away.
