Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a dryer for granular activated carbon. Background Technology

[0002] Activated carbon is a carbonaceous material with a highly developed porous structure, giving it excellent adsorption capacity. Its applications are wide-ranging, including water treatment, air purification, healthcare, the food industry, and various industrial processing steps. The preparation of activated carbon typically involves two steps: drying and screening. Screening is necessary because the shape of the activated carbon affects its adsorption performance and hydrodynamic properties, while drying removes moisture and other volatile substances to improve its adsorption performance and stability. Existing drying equipment is limited in function, only capable of drying activated carbon particles. Screening is still required after drying, necessitating two separate sets of equipment for these two steps, resulting in high production costs and low production efficiency. Utility Model Content

[0011] The feed pipe is fixed to the top of the rectangular shell;

[0012] Multiple fixed shells are respectively fixed to the outer side of multiple circular shells, and a heater is fixedly connected inside the fixed shell;

[0016] The motor is fixedly connected to the rectangular shell, and the output end of the motor passes through one side wall of the rectangular shell and the circular shell and is fixedly connected to one end of the auger.

[0017] Preferably, a collection shell is fixedly connected to the top of each of the multiple circular shells at the position corresponding to the air outlet. The top of the collection shell is connected to a connecting pipe, and one end of the connecting pipe passes through the side wall of the rectangular shell and extends to the outside of the rectangular shell.

[0018] Furthermore, the recycling mechanism includes:

[0024] Preferably, a water tank is fixedly connected to the bottom of the second circular shell, and an electrically controlled valve is fixedly connected to the bottom of the water tank.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. By setting a drying mechanism on the rectangular shell, the activated carbon granules are easily conveyed to the interior of the topmost circular shell through the feed pipe. By starting multiple motors, the auger rotates, thereby conveying the activated carbon granules. By starting multiple heaters, the activated carbon granules conveyed inside the circular shell are heated and dried. The water vapor generated during drying is discharged through the collection shell and connecting pipe. When the activated carbon granules are conveyed, they are filtered by a filter screen. The smaller activated carbon granules that fall after filtration will fall into the interior of the corresponding conveying shell and be conveyed to the interior of the next circular shell, thereby undergoing drying and filtration again. This enables the activated carbon granules to be dried and screened quickly, making it more convenient to use and improving the production efficiency of activated carbon granules. By controlling the heating temperature of the heaters on the outside of the multiple circular shells, the drying temperature inside the circular shells can be controlled, thereby ensuring the drying effect of the activated carbon granules.

[0027] 2. By setting a recovery mechanism on the rectangular shell and using multiple connecting pipes to facilitate the transportation of water vapor to the interior of the circular shell, and then using a waterproof and breathable membrane to isolate the moisture in the water vapor, hot air can flow into the interior of the conveying pipes, while the water collects and falls into the interior of the water storage tank for collection. An electronically controlled valve facilitates the discharge of the water collected in the water storage tank. By activating a high-temperature resistant fan, the flow of hot air is accelerated, and multiple air supply pipes transport the hot air to the interior of multiple conveying shells. The hot air blown out by the air supply pipes dries the activated carbon particles that have fallen into the conveying shells again. This achieves the recovery and reuse of heat from the water vapor discharged from the drying mechanism, reduces energy consumption, improves drying efficiency, and the blown hot air can also move the activated carbon particles inside the conveying shells, allowing the activated carbon particles inside the conveying shells to quickly collect, ensuring the collection effect of the conveying shells.

Detailed Implementation

[0034] 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.

[0035] Please see Figure 1-5 In this embodiment of the present invention, a dryer for granular activated carbon includes: a support frame 100, a drying mechanism 200 and a recycling mechanism 300. A rectangular shell 110 is fixedly connected to the top of the support frame 100, and a plurality of guide shells 120 are fixedly connected to the rectangular shell 110. The drying mechanism 200 is fixed to the rectangular shell 110 and is used to dry activated carbon granules. The recycling mechanism 300 is fixed to the rectangular shell 110.

[0036] Specifically, the drying mechanism 200 and the recycling mechanism 300 are used together to facilitate the drying and screening of activated carbon particles. Multiple guide shells 120 are used to guide the dried activated carbon particles discharged from the drying mechanism 200, making them easier to collect and use.

[0037] Example 1

[0038] like Figure 2-4As shown, in this embodiment, the drying mechanism 200 includes: multiple circular shells 210, a feed pipe 220, multiple fixed shells 230, and multiple conveying shells 250. The multiple circular shells 210 are staggered and fixed inside the rectangular shell 110. Each circular shell 210 has an air outlet 211, a discharge port 213, and a connecting hole 214. A screen 212 is fixedly connected inside the air outlet 211, and a filter screen 215 is fixedly connected inside the connecting hole 214. The multiple discharge ports 213 correspond to the multiple guide shells 120. A conveying assembly is provided on each circular shell 210. The feed pipe 220 is fixed to the top of the rectangular shell 110. The multiple fixed shells 230 are fixed to the outer sides of the multiple circular shells 210. A heater 231 is fixedly connected inside the fixed shells 230. The tops of the multiple conveying shells 250 are respectively connected to the multiple circular shells 210. The bottom of the rectangular shell 110 is fixedly connected to the bottom of the conveying shell 250. The top of the conveying shell 250 corresponds to the connecting hole 214. The inner bottom surface of the rectangular shell 110 is fixedly connected to the bottom of the corresponding conveying shell 250. The multiple round shells 210 are respectively fixedly connected to the feed pipe 220 and the bottom of the multiple conveying shells 250. The conveying assembly includes: auger 260 and motor 270. The auger 260 is rotatably connected to the inside of the round shell 210. The motor 270 is fixedly connected to the rectangular shell 110. The output end of the motor 270 passes through the side wall of the rectangular shell 110 and the round shell 210 and is fixedly connected to one end of the auger 260. The top of the multiple round shells 210 is fixedly connected to the position of the air outlet 211. The top of the collection shell 240 is fixedly connected to the connecting pipe 241, and one end of the connecting pipe 241 passes through the side wall of the rectangular shell 110 and extends to the outside of the rectangular shell 110.

[0039] In this embodiment, the feed pipe 220 facilitates the conveying of activated carbon particles to the interior of the topmost circular shell 210. Multiple motors 270 are activated to drive the auger 260, which in turn conveys the activated carbon particles. Multiple heaters 231 are activated to heat the sidewalls of the circular shell 210, thereby drying the activated carbon particles conveyed inside. The vent 211 facilitates the discharge of moisture generated during drying, and a screen 212 prevents activated carbon particles or powder from passing through the vent 211. The collection shell 240 and connecting pipe 241 facilitate the discharge of moisture from the rectangular shell 110. When the activated carbon particles conveyed by the circular shell 210 move to the connecting hole 214, a filter 215 is used to filter the activated carbon. The particles are filtered, and the smaller activated carbon particles that fall off after filtration will fall into the corresponding conveying shell 250 and be conveyed to the next round shell 210 for further drying and filtration. The larger activated carbon particles are conveyed by the auger 260 and discharged from the outlet 213, falling into the corresponding guide shell 120, which facilitates the collection of the dried activated carbon. The mesh size of the filter screen 215 on the multiple round shells 210 increases from top to bottom, thus achieving a multi-layer filtration effect. By controlling the heating temperature of the heater 231 on the outside of the multiple round shells 210, the activated carbon particles that have undergone multiple drying processes are prevented from being over-dried, and the drying effect of the activated carbon particles is ensured. The activated carbon filtered at the bottom is conveyed to the bottom of the rectangular shell 110 via the corresponding conveying shell 250, which facilitates its collection and makes it more convenient to use.

[0040] Example 2

[0041] Based on Example 1, in order to recover and utilize the heat in the water vapor discharged from the drying unit 200.

[0042] like Figure 5As shown, in this embodiment, the recycling mechanism 300 includes: a second circular shell 310, multiple second connecting pipes 320, a conveying pipe 330, and multiple air supply pipes 340. The second circular shell 310 is disposed on one side of the rectangular shell 110. The multiple second connecting pipes 320 are all connected and fixed to the second circular shell 310. One end of each of the multiple second connecting pipes 320 is connected and fixed to one end of each of the multiple first connecting pipes 241. One end of the conveying pipe 330 is connected and fixed to the top of the second circular shell 310. The other end of the conveying pipe 330 passes through the side wall of the rectangular shell 110 and is located on the rectangular shell. Inside 110, a waterproof and breathable membrane 331 is fixedly connected to one end of the conveying pipe 330. Multiple air supply pipes 340 are connected and fixed to the conveying pipe 330. One end of each of the multiple air supply pipes 340 is connected and fixed to one end of the top of multiple conveying shells 250. Screens 341 are fixedly connected to one end of each of the multiple air supply pipes 340. Multiple high-temperature resistant fans 332 are sleeved and fixed inside the conveying pipe 330. A water tank 350 is connected and fixed to the bottom of the round shell 310. An electric control valve 351 is connected and fixed to the bottom of the water tank 350.

[0043] In practice, water vapor discharged from multiple connecting pipes 241 is transported to the interior of the cylindrical shell 310 via multiple connecting pipes 320. The rising water vapor then flows to one end of the conveying pipe 330, where a waterproof and breathable membrane 331 isolates the moisture, allowing hot air to flow into the conveying pipe 330. The collected moisture condenses into droplets and falls into the water tank 350 for collection. An electrically controlled valve 351 facilitates the drainage of the collected water from the water tank 350. When hot air flows into the cylindrical shell 310, a high-temperature resistant fan 332 is activated to accelerate the flow of hot air. The system operates by using multiple air supply pipes 340 to deliver hot air into multiple conveying shells 250. The hot air blown out by the air supply pipes 340 re-dries the activated carbon particles that fall into the conveying shells 250, thus realizing the recovery and reuse of heat from the water vapor discharged from the drying mechanism 200, reducing energy consumption, improving drying efficiency, and the blown hot air can also move the activated carbon particles inside the conveying shells 250, allowing the activated carbon particles inside the conveying shells 250 to quickly gather, ensuring the collection effect of the conveying shells 250. Furthermore, the use of screen 341 can prevent activated carbon particles from entering the interior of 340.
