Description

Technical Field

[0001] This utility model relates to the field of water purification agent production technology, specifically to a rotary drying equipment for powdered water purification agents. Background Technology

[0002] After manufacturing, water purification agents generally contain a certain amount of moisture, which makes them inconvenient to package and use. Therefore, a special drying device is used to dehydrate them.

[0003] The existing publicly available technology, application number CN202421740024.6, describes a drum-type drying device for a water purification agent. This device completely seals the drying drum with end caps to ensure that the water purification agent does not escape. Then, it uses an exhaust net to discharge the high-temperature water vapor inside the drying drum. The entire structure can effectively prevent the water purification agent from escaping and can effectively ensure the discharge of water vapor.

[0004] However, the aforementioned patent still has certain drawbacks in use: it uses a heated base for drying, which limits the overall heating area. The drying effect of the water purification agent in the middle of the drum is significantly different from that of the water purification agent on the outside near the heated base, thus affecting the overall drying uniformity and effect, and hindering better drying. In addition, after drying, it needs to be left to stand for a long time to allow the powdered water purification agent to settle, which takes a long time, affects work efficiency, reduces the practicality of the device, and the overall effect is not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a rotary drying device for powdered water purification agents, which has the following beneficial effects:

[0020] (1) This utility model adopts a drive shaft, stirring rod and heating chamber. After the water purification agent is added, the reverse rotation of the drying tank and the drive shaft can make the water purification agent inside more fully stirred, so that the water purification agent in different positions can be fully exposed and come into contact with the drive shaft, stirring rod and heating chamber after high temperature heating, so as to realize the heating and drying operation. Furthermore, through the heat conduction from the inside to the outside of the drive shaft and stirring rod and the heat conduction from the outside to the inside of the heating chamber, the overall heat conduction area can be effectively expanded, thereby increasing the heat-receiving area of ​​the water purification agent, improving the drying effect of the water purification agent, and facilitating faster drying operation.

[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0030] According to an embodiment of the present invention, a rotary drying device for powdered water purification agents is provided.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, the rotary drying device for powdered water purifier according to an embodiment of the present invention includes a drying drum 1 and a base 20. A limiting plate 15 is rotatably connected to the middle position inside one side surface of the drying drum 1. A drive shaft 5 is fixedly installed in the middle position of the limiting plate 15. One end of the drive shaft 5 passes through one side of the drying drum 1 and is connected to a stirring rod 4. The stirring rod 4 is arranged around the surface of the drive shaft 5. A heating pipe 12 is rotatably connected to the other end of the drive shaft 5. A heating chamber 2 is formed around the outer periphery of the limiting plate 15 inside the surface of the drying drum 1. Several sets of air outlets 16 are formed on the surface of the limiting plate 15. Cavities for introducing heating air are formed inside the drive shaft 5 and inside the stirring rod 4.

[0032] In one embodiment, several sets of electrostatic adsorption plates 3 are uniformly installed around the inner surface of the drying drum 1. The electrostatic adsorption plates 3 are connected to the storage battery 22 via wires. The storage battery 22 is located on the surface of the drying drum 1. The electrostatic adsorption plates 3 are set up to adsorb the floating water purification agent by generating static electricity, thereby shortening the settling time of the water purification agent and making it easier to remove the water purification agent more quickly. The water purification agent powder can theoretically be electrostatically adsorbed. According to the principle of electrostatic adsorption, when an object with static electricity approaches another object without static electricity, due to electrostatic induction, the side of the uncharged object closest to the charged object will generate a charge of opposite polarity to the charge carried by the charged object, and the other side will generate the same number of charges of the same polarity. Since opposite charges attract each other, electrostatic attraction will occur.

[0033] In one embodiment, a support frame 21 is symmetrically fitted around the outer periphery of the drying drum 1, and a base 20 is fixedly installed at the bottom of the support frame 21. The base 20 and the support frame 21 can fix the entire device, which can enhance the overall stability of use. The battery 22 is set to power the electrostatic adsorption plate 3. Similarly, a controller can be installed on the surface of the drying drum 1 to control the use of the battery 22 and the electrostatic adsorption plate 3. Since there are various types of controllers and the application technology is mature, personnel can choose according to their needs and implement it through programming. This will not be elaborated on further here.

[0034] In one embodiment, an end cap 17 is rotatably connected to one side surface of the drying drum 1, and the end cap 17 is fixed to the drying drum 1 by bolts. An exhaust screen 19 is provided in the middle of the surface of the end cap 17. The exhaust screen 19 is provided to discharge the moisture generated during drying and to avoid the residual moisture affecting the overall drying effect.

[0035] In one embodiment, a gear ring 14 is welded to the middle of the other side surface of the drying drum 1. A first drive gear 6 is meshed with the bottom of the gear ring 14. A reducer 7 is connected to one end of the first drive gear 6, and a first motor 8 is connected to the other end of the reducer 7. The reducer 7 is designed to increase the torque, thereby better driving the gear ring 14 and realizing the rotation operation of the drying drum 1. This allows the water purification agent inside to be turned over, making it easier to expose the water purification agent in different positions, increasing the contact area with heat, and thus better performing the drying operation.

[0036] In one embodiment, a transmission gear 13 is fixedly installed at one end of the drive shaft 5 on the outside of the drying drum 1. A second drive gear 11 is meshed with the surface of the transmission gear 13. A second motor 10 is connected to one end of the second drive gear 11. A mounting bracket 9 is installed at the bottom of the second motor 10. The bottom of the mounting bracket 9 is fixed to the base 20. The second motor 10 is set to drive the drive shaft 5, so that it can rotate, thereby agitating the water purification agent inside, expanding the contact area, and facilitating more thorough drying treatment in the future.

[0037] In one embodiment, a scraper 18 is fixedly installed at one end of the drive shaft 5 inside the drying drum 1, and the scraper 18 is in contact with the exhaust screen 19. The scraper 18 is designed to scrape off the water purification agent adhering to the surface of the exhaust screen 19 when it rotates, so as to avoid clogging the holes and preventing the moisture generated during drying from being discharged smoothly. Therefore, the size of the holes needs to be sufficient to allow water vapor to pass through, but not to allow the water purification agent to be discharged, so as to avoid loss of water purification agent during use.

[0038] In one embodiment, the heating pipe 12 is connected to an external steam generator. Steam generators are common devices with various types and mature technology, so they will not be described in detail. Here, the main purpose is to generate high-temperature hot air, and then use this heat to dry the powdered water purification agent.

[0039] Working Principle: In actual use, personnel can open the side of the drying drum 1 by rotating the end cap 17, at which point the powdered water purification agent to be dried can be added. Then, closing the end cap 17 again seals the drying drum 1. The operation of the first motor 8 drives the first drive gear 6 to engage the gear ring 14, thereby rotating the drying drum 1. Simultaneously, the second motor 10 drives the drive shaft 5 to rotate via the rotation of the second drive gear 11 and the transmission gear 13. The rotation direction of the drive shaft 5 is opposite to that of the drying drum 1. This reverse rotation allows the water purification agent to make more thorough contact with the drive shaft 5 and the stirring rod 4 on its surface. Furthermore, hot gas flows inside the drive shaft 5 and the stirring rod 4, ensuring sufficient contact and allowing heat to be applied more effectively to the water purification agent, thus better drying it. The water purification agent undergoes a drying process, and a limiting plate 15 is provided at the contact position between the drive shaft 5 and the drying barrel 1. Hot gas can be introduced into the heating chamber 2 through the air outlet 16 on the surface of the limiting plate 15. The heating chamber 2 can dry the water purification agent that falls on its surface. Through the heat conduction from the inside to the outside of the drive shaft 5 and the stirring rod 4, and the heat conduction from the outside to the inside of the heating chamber 2, the overall heat conduction area can be effectively expanded, thereby increasing the heating area of ​​the water purification agent and improving the drying effect of the water purification agent, which facilitates faster drying operations. After drying is completed, the electrostatic adsorption plate 3 generates static electricity through the power supply of the battery 22, which then adsorbs and settles the floating powdered water purification agent, shortening the settling speed of the water purification agent. This makes it easier for personnel to take out the water purification agent for use in a timely manner, reducing the waiting time and facilitating better use of the device. The device as a whole has the advantages of good drying effect, comprehensive heating, and sedimentation assistance.
