Description

Technical Field

[0001] This utility model relates to the field of low-temperature drying technology for photocatalysts, specifically a low-temperature drying device for photocatalysts. Background Technology

[0002] Photocatalysts are materials that accelerate chemical reactions under light and are commonly used to purify air and water and decompose harmful substances. They are widely used in indoor air purification (such as formaldehyde removal), wastewater treatment, self-cleaning surfaces (such as antibacterial coatings), and solar energy utilization, and are characterized by high efficiency, environmental friendliness, and no secondary pollution.

[0003] Photocatalysts require rigorous cleaning and drying during recycling. In existing technologies, cleaning and drying operations are usually completed using two separate sets of equipment. Operators must first place the photocatalyst to be treated into the cleaning equipment for rinsing, and then manually transfer the wet catalyst to the low-temperature drying equipment for drying. Therefore, the material is easily exposed to the air during the cross-equipment transfer process, and suffers from secondary pollution such as dust and microorganisms, which directly affects the subsequent performance of the catalyst. In addition, the equipment switching and material handling are time-consuming and labor-intensive, and the purchase cost and site occupation cost of the two sets of cleaning and drying equipment are relatively high. To address this, we propose a low-temperature drying device for photocatalysts. Utility Model Content

Through an integrated design, the photocatalysts can be continuously cleaned and dried within the same drying chamber, completely eliminating intermediate steps such as material transfer and drying between two sets of equipment. This effectively avoids the risk of secondary pollution during transfer, significantly shortens the single processing cycle, and reduces the need for purchasing independent cleaning equipment and the space occupied, thereby lowering equipment investment costs and solving the problems mentioned earlier.

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.

[0016] Please see Figure 1-4This utility model provides a technical solution: a low-temperature drying device for photocatalysts, including a drying chamber 1. A drying chamber 9 is provided on the front side of the interior of the drying chamber 1. Several pull-out grooves 3 are opened on the front side of the drying chamber 9. A material feeding box 4 is slidably inserted into each of the pull-out grooves 3. A handle 5 is fixedly connected to the middle of the front side of each of the material feeding boxes 4. Several filter holes are opened through the left, right and bottom sides of each of the material feeding boxes 4. A sliding groove 11 is opened on the left and right sides of each of the material feeding boxes 4. A slide rail 10 is fixedly installed on the left and right sides of the pull-out grooves 3 inside the drying chamber 9. The slide rail 10 is slidably connected to the sliding groove 11.

An exhaust component is installed on the top of the drying chamber 9.

[0017] When the photocatalyst low-temperature drying device is in operation, the operator first holds the handle 5 on the front side of the discharge box 4 and pulls the discharge box 4 outward along the slide rails 10 on the left and right sides of the pull-out groove 3 inside the drying chamber 9. The slide rails 11 on the left and right sides of the discharge box 4 slide and engage with the slide rails 10 to ensure smooth pulling. After the photocatalyst is placed into the discharge box 4, it is pushed back into the pull-out groove 3 along the slide rails 10 using the handle 5 to complete the loading. When the photocatalyst needs to be pre-treated by cleaning, the cleaning components inside the drying chamber 9 are activated, and clean water can pass through the left, right and bottom sides of the discharge box 4. The filter pores penetrate to the surface of the material to achieve uniform cleaning, and the waste liquid can also be discharged through the filter pores.

The generated low-temperature hot air diffuses in the chamber and penetrates through the filter pores of the discharge box 4 to fully contact the photocatalyst, quickly removing moisture and avoiding high temperature damage to activity. At the same time, the moisture and volatile gases generated during the drying process are promptly extracted by the exhaust component at the top of the drying chamber 9 to maintain a dry environment in the chamber to ensure drying efficiency and photocatalyst activity. All structures work together to achieve low-temperature drying treatment of the photocatalyst.

[0018] The hot air drying assembly includes two sets of hot air boxes 12, which are installed on the left and right sides of the inside of the drying chamber 9, respectively. Several air outlets 17 are installed on the side of the two sets of hot air boxes 12 that are close to each other.

An air supply pipe 19 is fixedly installed through the bottom side of the inside of the drying chamber 9. The output end of the air supply pipe 22 is fixedly connected to the bottom side surface of the air supply pipe 19. The top output end of the air supply pipe 19 is fixedly connected to the air supply pipe 18. The left and right ends of the air supply pipe 18 extend into the inside of the two sets of hot air boxes 12, and several air outlets 16 are fixedly connected to the left and right sides of the air supply pipe 18. The air outlets 17 are fixedly connected to the air outlets 16.

[0019] When the hot air drying assembly is working, after the hot air blower 23 on the bottom side of the drying chamber 1 is started, the hot air generated by the hot air blower 23 is sent into the air supply pipe 22 through the output end. The output end of the air supply pipe 22 is fixedly connected to the bottom side surface of the air supply pipe 19 fixedly installed on the bottom side of the drying chamber 9. The hot air then flows into the air supply pipe 19. The top output end of the air supply pipe 19 is fixedly connected to the air supply pipe 18. The hot air is further introduced into the air supply pipe 18. The left and right ends of the air supply pipe 18 extend into the two sets of hot air boxes 12 installed on the left and right sides of the drying chamber 9, respectively. Several air outlet pipes 16 fixedly connected on the left and right sides of the air supply pipe 18 are fixedly connected to the air outlet hoppers 17 in the hot air box 12. Finally, the hot air is delivered to the air outlet hoppers 17 through the air outlet pipes 16 and blown out evenly by several air outlet hoppers 17 close to one side of the two sets of hot air boxes 12, acting on the material in the drying chamber 9 to achieve drying.

[0020] The cleaning assembly includes a water pump 24, which is fixedly installed on the bottom side of the inside of the drying chamber 1.

The input ends of the several water supply pipes 14 are fixedly connected to the outlet pipe 26. A sewage discharge mechanism is also provided inside the drying chamber 9.

[0021] The sewage discharge mechanism includes a drain pipe 21. A drain outlet 20 is provided through the bottom side of the drying chamber 9. The drain pipe 21 is fixedly connected to the bottom output end of the drain outlet 20. The bottom end of the air supply pipe 19 is fixedly connected to a solenoid valve 27. The output end of the solenoid valve 27 is fixedly connected to a connecting pipe 28. The output end of the connecting pipe 28 is fixedly connected to the side surface of the drain pipe 21.

[0022] When the cleaning assembly is working, the water pump 24 on the bottom side of the drying chamber 1 is started. The water pump 24 introduces clean water through the inlet pipe 25 at the input end. The clean water is delivered to several water supply pipes 14 on the top of the placement rack 13 in the drying chamber 9 through the outlet pipe 26 at the output end of the water pump 24. The placement rack 13 is correspondingly set on the top side of the material box 4. Several rinsing nozzles 15 fixedly connected to the bottom side of the water supply pipe 14 spray out cleaning liquid to rinse the material in the material box 4. The waste liquid generated by cleaning is collected in the drying chamber 9 and flows into the drain pipe 21 fixedly connected to the bottom output end through the drain port 20 opened through the bottom side of the interior, and finally discharged from the equipment. At the same time, the solenoid valve 27 fixedly connected to the bottom end of the air supply pipe 2 19 can be opened as needed. The water remaining in the air supply pipe 2 19 during the cleaning process can be discharged together through the solenoid valve 27 and the connecting pipe 28 at the output end into the drain pipe 21, realizing centralized sewage discharge.

[0023] The exhaust assembly includes an exhaust fan 8, an exhaust port 7 is provided in the middle of the top side of the drying chamber 9, the exhaust fan 8 is fixedly installed on the bottom side of the exhaust port 7, and an exhaust pipe 6 is fixedly connected to the top output end of the exhaust port 7.

[0024] When the exhaust system is working, when the drying chamber 9 generates moisture or volatile gases during cleaning or drying operations, the exhaust fan 8 fixedly installed on the bottom side of the exhaust port 7 is activated. The exhaust fan 8 generates negative pressure suction, which draws the moisture and gases inside the drying chamber 9 into the exhaust port 7 in the middle of the top side. Then, these airflows are discharged outward through the exhaust pipe 6 fixedly connected to the top output end of the exhaust port 7, thereby achieving air circulation inside the drying chamber 9 and maintaining a dry environment.

[0025] The control panel 2 is installed on the top right side of the drying oven 1. As the control core of the equipment, the control panel 2 can receive operation instructions and transmit control signals to various functional components of the equipment, so as to realize the start-up, shutdown and operation status regulation of components such as exhaust fan 8, water pump 24, hot air blower 23, and solenoid valve 27, thereby coordinating the orderly development of various links such as cleaning, drying, sewage discharge and ventilation.

[0026] Working principle: When the photocatalyst low-temperature drying device is working, firstly, the operator holds the handle 5 on the front side of the discharge box 4 and pulls the discharge box 4 outward along the slide rails 10 on the left and right sides of the pull-out groove 3 inside the drying chamber 9. The slide rails 11 on the left and right sides of the discharge box 4 slide and engage with the slide rails 10 to ensure smooth pulling. After the photocatalyst is placed into the discharge box 4, it is pushed back into the pull-out groove 3 along the slide rails 10 by the handle 5 to complete the loading. When the photocatalyst needs to be cleaned and pretreated, the water pump 24 on the bottom side inside the drying chamber 1 is started. The water pump 24 introduces clean water through the inlet pipe 25 at the input end. The clean water is delivered to several water supply pipes 14 on the top of the placement rack 13 inside the drying chamber 9 through the outlet pipe 26 at the output end of the water pump 24. The placement rack 13... A number of rinsing nozzles 15, which are fixedly connected to the bottom side of the water supply pipe 14 and set on the top side of the material discharge box 4, spray out cleaning liquid to rinse the material in the material discharge box 4. The clean water can penetrate to the surface of the material through the filter holes on the left, right and bottom sides of the material discharge box 4 to achieve uniform cleaning. The waste liquid can also be discharged through the filter holes. The waste liquid generated by cleaning is collected in the drying chamber 9 and flows into the drain pipe 21 fixedly connected to the bottom output end through the drain port 20 opened through the bottom side of the interior, and finally discharged from the equipment. At the same time, the solenoid valve 27 fixedly connected to the bottom end of the air supply pipe 29 can be opened as needed. The water remaining in the air supply pipe 29 during the cleaning process can be introduced into the drain pipe 21 through the solenoid valve 27 and the connecting pipe 28 at the output end and discharged together to achieve centralized sewage discharge. After the hot air blower 23 is started inside the drying chamber 1, the hot air generated by the hot air blower 23 is sent into the air supply pipe 22 through the output end. The output end of the air supply pipe 22 is fixedly connected to the bottom surface of the air supply pipe 19 fixedly installed inside the drying chamber 9. The hot air then flows into the air supply pipe 19. The top output end of the air supply pipe 19 is fixedly connected to the air supply pipe 18. The hot air is further introduced into the air supply pipe 18. The left and right ends of the air supply pipe 18 extend into the two sets of hot air boxes 12 installed on the left and right sides inside the drying chamber 9, respectively. Several air outlet pipes 16 fixedly connected to the left and right sides of the air supply pipe 18 are fixedly connected to the air outlet hoppers 17 inside the hot air boxes 12. The hot air is delivered to the air outlet hopper 17 through the air outlet duct 16. It is evenly blown out by several air outlet hoppers 17 on one side of the two sets of hot air boxes 12. It penetrates through the filter holes of the discharge box 4 and comes into full contact with the photocatalyst, quickly removing moisture and avoiding high temperature damage to activity. At the same time, the exhaust fan 8 fixedly installed on the bottom side of the exhaust port 7 is activated. The exhaust fan 8 generates negative pressure suction, which draws the moisture and gas inside the drying chamber 9 into the exhaust port 7 in the middle of the top side. Then, these airflows are discharged outward through the exhaust pipe 6 fixedly connected to the top output end of the exhaust port 7, maintaining a dry environment inside the chamber to ensure drying efficiency and photocatalyst activity. All structures work together to achieve low-temperature drying treatment of the photocatalyst.
