Description

Technical Field

[0001] This utility model relates to the field of dispersant production technology, specifically to an energy-saving and high-efficiency dryer for dispersant production. Background Technology

[0002] Dispersants are surfactants that possess both lipophilic and hydrophilic properties within their molecules. They can uniformly disperse solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids, while also preventing particle sedimentation and aggregation, thus forming a stable suspension. In the dispersant production process, the drying process is extremely critical and usually requires the use of drying equipment.

[0003] In the prior art, Chinese Patent Application No. CN202321785799.0 discloses a dryer for dispersant production, including a drying chamber and a circulating drying component. The circulating drying component is fitted onto the drying chamber and is used to agitate and dry the raw materials for dispersant production. The drying chamber has a perforated structure in the middle. By adding a turning plate, which is set close to the bottom wall of the drying chamber, the raw materials can be moved as much as possible, avoiding different drying rates inside and outside the raw materials, making the overall heating of the raw materials more uniform, thereby ensuring the uniformity of drying of the raw materials on the drying plate, increasing the drying effect of the device, and making the raw materials dry evenly.

[0004] Based on the above information, existing technologies for drying dispersants involve directly placing the raw materials into the drying chamber, which can easily lead to dispersant accumulation, increased stirring time, and consequently reduced drying efficiency and energy consumption. Therefore, we propose an energy-saving and efficient dryer for dispersant production. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving and efficient dryer for dispersant production, in order to solve the problem mentioned in the background art that when the existing technology is used to dry dispersants, the dispersant raw materials are directly placed into the drying chamber for drying, which easily causes the dispersant to accumulate, increases the stirring time, and thus affects the drying efficiency and increases energy consumption.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and efficient dryer for dispersant production, comprising a main body, a drying chamber inside the main body, a discharge port at the bottom of the main body, and a drying mechanism for drying the dispersant inside the drying chamber;

[0007] The drying mechanism includes a heater fixedly installed on the top of the main body of the device, with a water inlet pipe fixedly installed on the outer wall of the heater. A heat transfer pipe and a return pipe are fixedly installed on the outer wall of the main body of the device. A heating chamber is provided on the outer wall of the drying chamber. An atomizer is fixedly installed on the top of the main body of the device, with a feed hopper fixedly installed on the top of the atomizer and a feed pipe on the outer wall of the feed hopper. A spray pipe is fixedly installed on the inner wall of the top of the drying chamber, with a spray nozzle on the outer wall of the spray pipe. A drive motor is fixedly installed on the top of the main body of the device, with a stirring shaft fixedly installed at the end of the drive motor. A stirring blade and a scraper are fixedly installed on the outer wall of the stirring shaft. A recovery mechanism for recovering and utilizing the hot air inside the drying chamber is provided on the top of the main body of the device.

[0008] Furthermore, the heating chamber is located between the drying chamber and the main body of the device, and one end of the heat transfer pipe is connected to the heating chamber, while the other end of the heat transfer pipe is connected to the heater. One end of the return pipe is connected to the heating chamber, while the other end of the return pipe is connected to the heater.

[0009] Furthermore, one end of the atomizer is connected to the bottom of the feed hopper, and the other end of the atomizer is connected to the spray pipe. Multiple sets of spray pipes are arranged at equal angles at the top of the drying chamber, and multiple sets of nozzles are arranged at equal intervals on the outer wall of the spray pipe.

[0010] Furthermore, the length of the stirring shaft corresponds to the length of the drying chamber, and multiple sets of stirring blades are arranged at equal angles on the outer wall of the stirring shaft, with the length of the stirring blades being less than the distance between the outer wall of the stirring shaft and the inner wall of the drying chamber.

[0011] Furthermore, the scraper is designed in a spiral shape, and multiple sets of scrapers are arranged at equal angles on the outer wall of the stirring shaft, and the outer wall of the scraper is in contact with the inner wall of the drying chamber.

[0012] Furthermore, the recycling mechanism includes a recycling pipe fixedly installed on the outer wall of the heater, and a filter screen is provided at the end of the recycling pipe.

[0013] Furthermore, one end of the filter screen is connected to the top of the drying chamber, and the other end of the filter screen is connected to the recovery pipe.

[0014] Furthermore, one end of the recovery pipe is connected to the top of the filter screen, and the other end of the recovery pipe is connected to the heater.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This energy-efficient dryer for dispersant production utilizes a drying mechanism that employs heat generated by a heater, which is transferred via heat pipes to a heating chamber on the outer wall of the drying chamber. This indirectly heats the dispersant within the drying chamber, avoiding potential localized overheating from direct heating. Simultaneously, an atomizer atomizes the dispersant material fed from the hopper and sprays it evenly into the drying chamber through spray pipes and nozzles, increasing the contact area between the dispersant and the hot air. This allows the dispersant to dry rapidly. The stirring shaft rotates at high speed driven by a motor, with impeller blades further agitating the dispersant and accelerating moisture evaporation. Scrapers adhere closely to the inner wall of the drying chamber, promptly cleaning any dispersant adhering to the surface and preventing material accumulation. This effectively improves drying efficiency and reduces energy consumption.

[0017] Furthermore, by setting up a recovery mechanism, the hot air at the top of the drying chamber carries some heat and is filtered through a filter screen before being transported back to the heater via a recovery pipe. The filter screen prevents dispersant particles from entering the recovery pipe, ensuring the purity of the recovered gas. The recovered hot air is reused, reducing the energy consumed by the heater to reach the set temperature, thus realizing the recycling of heat. This further improves the energy-saving performance of the dryer, reduces production costs, and makes the entire drying process more environmentally friendly and efficient.

Detailed Implementation

[0025] 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.

[0026] Example 1: Please refer to Figure 1-6 This utility model provides the following technical solution: an energy-saving and high-efficiency dryer for dispersant production, comprising a main body 1, a drying chamber 101 inside the main body 1, a discharge port 103 at the bottom of the main body 1, and a drying mechanism for drying the dispersant inside the drying chamber 101. The drying mechanism includes a heater 5 fixedly installed on the top of the main body 1, and a water inlet pipe 501 fixedly installed on the outer wall of the heater 5. A heat transfer pipe 502 and a return pipe 503 are fixedly installed on the outer wall of the main body 1. The outer wall of the drying chamber 101 is provided with a heating chamber 102. An atomizer 3 is fixedly installed on the top of the main body 1, and a feed hopper 2 is fixedly installed on the top of the atomizer 3. A feed pipe 201 is provided on the outer wall of the feed hopper 2. A spray pipe 301 is fixedly installed on the inner wall of the top of the drying chamber 101, and a nozzle 302 is provided on the outer wall of the spray pipe 301. A drive motor 4 is fixedly installed on the top of the main body 1, and a stirring shaft 401 is fixedly installed at the end of the drive motor 4. A stirring blade 402 and a scraper are fixedly installed on the outer wall of the stirring shaft 401. 403. The heating chamber 102 is located between the drying chamber 101 and the main body 1 of the device. One end of the heat transfer pipe 502 is connected to the heating chamber 102, and the other end of the heat transfer pipe 502 is connected to the heater 5. One end of the return pipe 503 is connected to the heating chamber 102, and the other end of the return pipe 503 is connected to the heater 5. One end of the atomizer 3 is connected to the bottom of the feed hopper 2, and the other end of the atomizer 3 is connected to the spray pipe 301. Multiple sets of spray pipes 301 are arranged at equal angles at the top of the drying chamber 101. The nozzles 302 are arranged in multiple sets at equal intervals on the outer wall of the spray pipe 301. The length of the stirring shaft 401 is arranged corresponding to the length of the drying chamber 101. The stirring blades 402 are arranged in multiple sets at equal angles on the outer wall of the stirring shaft 401. The length of the stirring blades 402 is less than the distance between the outer wall of the stirring shaft 401 and the inner wall of the drying chamber 101. The scraper 403 is designed in a spiral shape. The scraper 403 is arranged in multiple sets at equal angles on the outer wall of the stirring shaft 401. The outer wall of the scraper 403 is in contact with the inner wall of the drying chamber 101.

[0027] During operation, heater 5 is turned on, converting electrical energy into heat energy. Water is continuously supplied to heater 5 through water inlet pipe 501. The generated high-temperature hot air enters the heating chamber 102 between drying chamber 101 and the main body 1 via heat transfer pipe 502. Heat conduction is used to indirectly heat the dispersant in drying chamber 101. This indirect heating method effectively avoids the localized overheating problem that can easily be caused by direct heating, ensuring the stability and uniformity of the drying process. Simultaneously, the dispersant raw material enters through feed hopper 2 and is converted into tiny droplets by atomizer 3. These droplets are then sprayed through spray pipes 301 installed at equal angles on the top of drying chamber 101 and spray nozzles 301 distributed at equal intervals. 2. The dispersant is evenly sprayed into the drying chamber 101. At this time, the contact area between the dispersant and the hot air increases significantly, and the heat is quickly transferred to the dispersant particles, accelerating the evaporation of moisture. The drive motor 4 drives the stirring shaft 401 to rotate at high speed. The multiple sets of stirring blades 402 on the stirring shaft 401 further stir and disperse the dispersant, enhance the heat exchange process, and further accelerate the evaporation of moisture. The spiral-shaped scraper 403, which is installed at equal angles on the stirring shaft 401, always has its outer wall in close contact with the inner wall of the drying chamber 101. When the stirring shaft 401 rotates, it can clean the dispersant adhering to the wall surface in time, prevent material accumulation, and ensure the continuous and efficient operation of the drying process.

[0028] Example 2: Based on Example 1, a recovery mechanism is also disclosed, the specific structure of which is as follows: The top of the main body 1 of the device is provided with a recovery mechanism for recovering and utilizing the hot air inside the drying chamber 101. The recovery mechanism includes a recovery pipe 6 fixedly installed on the outer wall of the heater 5, and a filter screen 601 is provided at the end of the recovery pipe 6. One end of the filter screen 601 is connected to the top of the drying chamber 101, and the other end of the filter screen 601 is connected to the recovery pipe 6. One end of the recovery pipe 6 is connected to the top of the filter screen 601, and the other end of the recovery pipe 6 is connected to the heater 5.

[0029] The recycling mechanism focuses on energy recovery and utilization to achieve energy conservation. As the drying process progresses, a large amount of water vapor carrying some heat accumulates at the top of the drying chamber 101. This water vapor first passes through the filter screen 601, which plays a crucial filtering role, effectively intercepting dispersant particles and ensuring that only pure hot air enters the recovery pipe 6. The filtered hot air flows along the recovery pipe 6 to the heater 5 and rejoins the heating cycle. Since the recovered hot air itself has a certain temperature, this reduces the energy required for the heater 5 to reach the set operating temperature. In this way, the dryer achieves the recycling of heat, which not only improves its own energy-saving performance but also reduces production costs, making the entire drying process more environmentally friendly and efficient, in line with the concept of sustainable development.
