Abstract
Description
Technical Field
[0001] This utility model relates to the field of tungsten oxide production technology, and in particular to a device for cooling and collecting fine tungsten oxide particles. Background Technology
[0002] Tungsten oxide (WO3) fine particles are yellow or orange powders with particle sizes ranging from nanometers to micrometers, characterized by a large specific surface area and high surface activity. Due to their unique electronic structure and semiconductor properties, these fine particles exhibit excellent performance in catalysis, sensing, and energy fields. For example, they can be used as highly efficient photocatalysts to degrade pollutants, as high-sensitivity gas sensors to detect toxic gases, and as anode materials for lithium-ion batteries to improve energy storage performance. Furthermore, nano-tungsten oxide can also be used to prepare smart electrochromic films and radiation-shielding composite materials, showing potential applications in energy-saving building materials and radiation protection.
[0003] The three main methods for producing tungsten oxide include thermal decomposition, hydrothermal synthesis, and sol-gel methods. All three methods use high-temperature environments for tungsten oxide production. Therefore, the tungsten oxide production process includes a cooling step to obtain tungsten oxide that can be used directly at room temperature.
[0004] Most existing cooling devices use wind power for cooling. However, tungsten oxide fine particles have a particle size of micrometers and are easily carried by the air to form dust. Therefore, the airtightness of the cooling device is required. Otherwise, if the particles are leaked and inhaled by the operators, it will affect their health. In addition, the cooling efficiency of air cooling is also low, and dust is easily generated when the fine particles are discharged after cooling. Utility Model Content
[0005] To overcome the problem that most cooling devices rely on air cooling, and that tungsten oxide particles, which are micron-sized, are easily carried by the air and form dust, the air-cooling device must be highly sealed. Otherwise, if the particles leak and are inhaled by the operators, it will affect their health. In addition, air cooling is also less efficient.
[0006] The technical solution of this utility model is as follows: a tungsten oxide fine particle cooling and collection device, including a cooling box, a collection bucket, and a guiding assembly. A heat exchange tube for heat exchange and cooling is provided on the inner side of the cooling box. A guiding assembly is provided on both sides of the cooling box. A nozzle is provided on the top of the cooling box. An auger is provided on the bottom of the cooling box. A collection bucket is provided on one side of the cooling box. A filter cloth is slidably connected to the inner side of the collection bucket. A second electric push rod for pushing the filter cloth to move is provided on the top of the collection bucket. A lower cover plate is rotatably connected to the bottom of the collection bucket. A first electric push rod for driving the lower cover plate to move is provided at the bottom of the lower cover plate.
[0007] Preferably, a discharge pipe is provided at the bottom of the cooling box, the discharge pipe is set at an angle upward, and the auger is located inside the discharge pipe and is rotatably connected to the discharge pipe.
[0008] Preferably, the guiding component includes a water tank and a partition plate, with water tanks on both sides of the cooling box and a partition plate on the inner side of the water tank.
[0009] Preferably, a water inlet pipe is provided at the bottom of one side of the water tank, a water outlet pipe is provided at the top of the other side of the water tank, a mounting bracket is provided above the nozzle, and a connecting pipe is provided between the mounting bracket and the water outlet pipe.
[0010] Preferably, the heat exchange tubes of different levels are staggered, and the outer side of the heat exchange tubes is provided with fins to increase the heat exchange area, and the bottom of the fins is provided with protrusions for water collection.
[0011] Preferably, a support frame is provided above the filter cloth, the support frame is fixedly connected to the edge of the filter cloth, and a support filler is provided between the support frame and the filter cloth, the support filler being gravel.
[0012] Preferably, the support frame has holes for water permeation, and a drain pipe is installed above the support frame, with one end of the drain pipe fixedly connected to the support frame. The other end of the drain pipe is fixedly connected to a water pump.
[0013] The beneficial effects of this utility model are:
[0014] By passing air containing fine tungsten oxide particles into a cooling box, heat exchange tubes cool the air, thereby cooling the tungsten oxide particles. Water is sprayed from nozzles to purify the air, collecting the tungsten oxide particles in water droplets while further cooling them. Then, an auger sends the water and tungsten oxide together into a collection bucket. A second electric push rod pushes the filter cloth down to squeeze the water out of the tungsten oxide, turning the fine tungsten oxide particles into a mud cake. This prevents the fine tungsten oxide particles from forming dust during transportation. After drying, the mud cake becomes the finished fine tungsten oxide product. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-6 This utility model provides an embodiment of a tungsten oxide fine particle cooling and collection device, comprising a cooling box 1, a collection bucket 3, and guiding components. A heat exchange tube 4 for heat exchange and cooling is provided inside the cooling box 1. Guiding components are provided on both sides of the cooling box 1. A nozzle 6 is provided above the cooling box 1. An auger 5 is provided at the bottom of the cooling box 1. A collection bucket 3 is provided on one side of the cooling box 1. A filter cloth 8 is slidably connected to the inside of the collection bucket 3. A second electric push rod 9 for pushing the filter cloth 8 is provided above the collection bucket 3. A lower cover plate 301 is rotatably connected to the bottom of the collection bucket 3. A bottom of the lower cover plate 301 is provided with a... The first electric push rod 7 drives the movement of the lower cover plate 301; by passing air containing fine tungsten oxide particles into the cooling box 1, the heat exchange tube 4 cools the air, thereby cooling the tungsten oxide particles, and the nozzle 6 sprays water to purify the air, collecting the tungsten oxide particles in water droplets and further cooling them, then the auger 5 sends the water and tungsten oxide together into the collection bucket 3, and the second electric push rod 9 pushes the filter cloth 8 down to squeeze out the water in the tungsten oxide, so that the fine tungsten oxide particles become a mud cake, preventing the fine tungsten oxide particles from forming dust with the air during transportation. After the mud cake is dried, it can become the finished fine tungsten oxide particles.
[0024] Please see Figure 2 In this embodiment, a discharge pipe 101 is provided at the bottom of the cooling box 1. The discharge pipe 101 is set at an angle upward. The auger 5 is located inside the discharge pipe 101 and is rotatably connected to the discharge pipe 101. Tungsten oxide particles in the air are wrapped by precipitation and fall into the discharge pipe 101. The auger 5 rotates to transport the water-wetted and agglomerated tungsten oxide particles and send them into the collection bucket 3.
[0025] Please see Figures 3-4In this embodiment, the guiding component includes a water tank 2 and a partition plate 201. Water tanks 2 are arranged on both sides of the cooling tank 1, and a partition plate 201 is arranged inside the water tank 2. An inlet pipe 202 is arranged at the bottom of one side of the water tank 2, and an outlet pipe 203 is arranged above the other side of the water tank 2. A mounting bracket 601 is arranged above the nozzle 6, and a connecting pipe 602 is arranged between the mounting bracket 601 and the outlet pipe 203. Heat exchange tubes 4 of different levels are staggered. Fins 401 to increase the heat exchange area are arranged on the outer side of the heat exchange tubes 4, and protrusions 402 for water collection are arranged at the bottom of the fins 401. Cooling water is drawn from the inlet pipe... Water is introduced into water tank 2 through heat exchange tube 4 and passes through cooling box 1 to cool the airflow, thereby cooling the tungsten oxide particles. The cooling water continuously enters and leaves the cooling box 1 under the guidance of partition plate 201. Then it enters connecting pipe 602 from water outlet pipe 203 and is sprayed out from nozzle 6. After the water droplets come into contact with the tungsten oxide particles in the airflow, they are wrapped with the tungsten oxide particles and fall down. The staggered heat exchange tubes 4 can form resistance to the airflow, reduce the airflow velocity, prolong the heat exchange time, and ensure cooling efficiency. The water droplets falling above the heat exchange tubes 4 fall down due to gravity and flow along the protrusion 402 to gather and become water droplets again before falling down.
[0026] Please see Figures 5-6 In this embodiment, a support frame 801 is provided above the filter cloth 8. The support frame 801 is fixedly connected to the edge of the filter cloth 8. A support filler 802 is provided between the support frame 801 and the filter cloth 8. The support filler 802 is made of crushed stone. The support frame 801 has holes for water permeability. A drain pipe 803 is provided above the support frame 801. One end of the drain pipe 803 is fixedly connected to the support frame 801. The other end of the drain pipe 803 is connected and fixed to the water pump; the second electric push rod 9 pushes the support frame 801 downward and drives the filter cloth 8 downward to squeeze the tungsten oxide, squeezing out the water in the tungsten oxide. The squeezed water passes through the filter cloth 8, the support filler 802 and the support frame 801 and remains in the area above the collection bucket 3. The external water pump draws out the water through the drain pipe 803. Then the first electric push rod 7 shortens and opens the lower cover plate 301. The water remaining in the tungsten oxide causes the tungsten oxide to form a mud cake-like mass. The mass falls off under the action of gravity without forming dust and is easy to transfer within the factory. The mass can be naturally air-dried or dried to become fine tungsten oxide particles again.
[0027] In operation, airflow carries fine tungsten oxide particles into cooling chamber 1. The airflow moves upward, and cooling water enters water tank 2 through inlet pipe 202. The water flows through heat exchange pipes 4 through cooling chamber 1 to cool the airflow, thereby cooling the tungsten oxide particles. Guided by partition plate 201, the cooling water continuously enters and exits the cooling chamber 1, then enters connecting pipe 602 through outlet pipe 203 and is sprayed out from nozzle 6. The water droplets contact the tungsten oxide particles in the airflow, encapsulating them before falling. The staggered arrangement of heat exchange pipes 4 creates resistance to the airflow, reducing the airflow velocity and extending the heat exchange time, ensuring cooling efficiency. Water droplets falling above heat exchange pipes 4 fall due to gravity, flow along the protrusions 402, gather, and fall again as water droplets. The tungsten oxide particles in the air... The tungsten oxide particles, wetted and agglomerated by the rainwater, fall into the discharge pipe 101. The rotating auger 5 transports these particles into the collection tank 3. The second electric push rod 9 pushes the support frame 801 downward, causing the filter cloth 8 to move downward and squeeze the tungsten oxide, extracting the water. The extracted water passes through the filter cloth 8, the support filler 802, and the support frame 801, remaining in the area above the collection tank 3. An external water pump extracts the water through the drain pipe 803. Then, the first electric push rod 7 shortens and opens the lower cover 301. The residual water in the tungsten oxide causes it to form mud-cake-like clumps. These clumps fall off under gravity without creating dust and are easy to transfer within the plant. The clumps can be naturally air-dried or dried to become fine tungsten oxide particles again.
[0028] Preferably, through the above steps, air containing fine tungsten oxide particles is introduced into the cooling box 1, and the heat exchange tube 4 cools the air, thereby cooling the tungsten oxide particles. Water is sprayed from the nozzle 6 to purify the air, and the tungsten oxide particles are collected in water droplets while being further cooled. Then, the auger 5 sends the water and tungsten oxide together into the collection bucket 3. The second electric push rod 9 pushes the filter cloth 8 down to squeeze out the water from the tungsten oxide, turning the fine tungsten oxide particles into a mud cake. This prevents the fine tungsten oxide particles from moving with the air and forming dust during transportation. After drying, the mud cake becomes the finished fine tungsten oxide product.
