Description

Technical Field

[0001] The present invention relates to the technical field of aerogel coating production equipment, and specifically provides a feeding device and a conveying method for producing aerogel coatings. Background Art

[0002] China's green building industry is booming. As an efficient heat insulation material, aerogel coatings have seen an explosive growth in demand in fields such as construction and industrial pipelines due to their excellent energy-saving performance. However, there are many bottlenecks in the feeding process during the current domestic production of aerogel coatings. On the one hand, traditional feeding devices cannot be adjusted in sync according to the feeding speed, resulting in energy waste or raw material blockage. At the same time, raw material dust adheres to the inner wall of the tank or crystallizes and forms blocks after long-term stillness, affecting the feeding efficiency. On the other hand, the problem of equipment cleaning not only increases the production time cost and labor cost but also may cause raw material residue pollution, affecting the quality of subsequent products.

[0003] More critically, with the in-depth promotion of the concept of intelligent manufacturing in the domestic manufacturing industry, traditional feeding devices cannot accurately adjust the raw material flow rate according to the real-time requirements on the production line, causing great energy waste. Against this background, it is of extremely urgent practical significance to develop a feeding device for producing aerogel coatings that integrates efficient stirring, precise feeding, synchronous speed regulation, and convenient cleaning to enhance the overall competitiveness of China's aerogel coating industry and promote the high-quality development of the green building materials industry. Summary of the Invention

[0006] Further, a conical plate is fixedly provided below the feeding cylinder. A feeding port is opened in the middle of the conical plate. A feeding port is provided above the feeding cylinder.

[0007] Further, the cleaning device includes a cleaning ring fixedly installed on the surface of the stirring shaft. A number of cleaning rods are evenly arranged on the surface of the cleaning ring. A vertical rod is fixedly provided at one end of the cleaning rod. The vertical rod is adaptively in contact with the inner wall of the feeding cylinder.

[0008] Further, the feeding device includes a feeding pipe fixedly installed at the air outlet end of the transmission fan. A material transmission pipe is fixedly provided above the feeding pipe. The inner wall of the material transmission pipe is adapted to the threaded rod. A switch is fixedly provided at one end of the feeding pipe. An electromagnetic valve is fixedly provided on the inner wall of the feeding pipe. A dust-proof net is fixedly provided on the inner wall of the feeding pipe.

[0009] Further, the cleaning device includes a cleaning pump fixedly installed above the inner wall of the feeding cylinder. A water inlet is provided above the cleaning pump. A distribution pipe is fixedly provided at the water outlet end of the cleaning pump.

[0010] Further, the inclination of the distribution pipe faces the inner wall of the feeding cylinder.

[0011] Further, a conveying method of a feeding device for producing aerogel paint includes the following steps: S1: Add the raw materials required for producing aerogel paint to the feeding port above the feeding cylinder. Open the switch at one end of the feeding pipe, and at the same time, use the control device to control the electromagnetic valve to open. S2: Start the transmission fan. The output end of the transmission fan drives the first transmission gear to rotate. The first transmission gear drives the second transmission gear to rotate through the transmission belt, and then drives the transmission rod to rotate. The transmission bevel gear at the other end of the transmission rod meshes with the stirring bevel gear, driving the stirring shaft to rotate. The stirring rings and stirring rods on the surface of the stirring shaft stir and mix the raw materials in the feeding cylinder. At the same time, the cleaning device fixed below the stirring shaft rotates with the stirring shaft. The cleaning rods and vertical rods on the surface of the cleaning ring clean the inner wall of the feeding cylinder to prevent the raw materials from adhering to the cylinder wall. S3: During the stirring process, as the stirring shaft rotates under the action of force, it drives the lower threaded rod to rotate inside the feeding pipe. When the threaded rod rotates, the raw materials in the feeding cylinder are transported into the feeding pipe through the threads on its surface. At the same time, the driving fan operates to generate wind force, and the stirred aerogel coating is transported out through the feeding pipe. The dust-proof net in the feeding pipe can prevent raw materials from entering the feeding pipe, ensuring the quality of the transported coating. S4: After the feeding work is completed, the feeding cylinder needs to be cleaned. At this time, use the control device to close the solenoid valve, connect the water source to the water inlet above the cleaning pump, and start the cleaning pump. The cleaning pump sprays water through the distribution pipe. The distribution pipe is inclined 30 degrees towards the inner wall of the feeding cylinder, so that the water can evenly wash the inner wall of the feeding cylinder. The sewage after cleaning is discharged from the feeding port in the middle of the conical plate at the bottom of the feeding cylinder into the feeding pipe and the waste water is discharged. At the same time, repeat S2 during the spraying process to ensure the cleanliness of the inner wall of the feeding cylinder and prevent adhesion to the inner wall from affecting subsequent use.

[0012] The beneficial effects of this technical solution are as follows: (1) Through the transmission device, the same-frequency adjustment of the stirring device and the feeding device is realized. The stirring speed is reasonably adjusted according to the feeding speed, avoiding energy waste and raw material blockage, enabling the entire feeding process to be more smooth and efficient, effectively shortening the production cycle, increasing the output per unit time, and meeting the requirements of large-scale production.

[0013] (2) While the stirring device stirs the raw materials, the cleaning device cleans the inner wall of the feeding cylinder, effectively preventing the adsorption and crystallization of raw material dust into blocks. This not only improves the feeding efficiency but also reduces the wear of the equipment caused by the adhesion and caking of raw materials, extends the service life of the equipment, and reduces the equipment maintenance cost.

[0014] (3) The cleaning device can efficiently clean the feeding cylinder after the feeding work is completed, reducing the cleaning time and labor cost, avoiding raw material residue pollution, ensuring the cleanliness inside the equipment before each feeding, thus ensuring the stable quality of the aerogel coating produced subsequently, reducing the defective rate, and enhancing the market competitiveness of the product.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] The specific implementation process is as follows: Embodiment 1: Please refer to Figures 1-4, a technical solution provided by the present invention: a feeding device and a conveying method for producing aerogel coatings, including a support plate 1. The support plate 1 serves as the basic support structure of the entire device. Above the support plate 1, a support ring 2 is fixedly installed. Above the support ring 2, a feeding cylinder 3 is fixedly installed. The feeding cylinder 3 is a key component for raw material stirring and temporary storage. Below the feeding cylinder 3, a conical plate 301 is fixedly installed. A feeding port is opened in the middle of the conical plate 301 to facilitate the discharge of the coating. Above the feeding cylinder 3, a feeding port 302 is installed to facilitate the addition of raw materials. Inside the inner wall of the feeding cylinder 3, a stirring device 4 is adaptively installed. The stirring device 4 is used to fully mix the raw materials. The stirring device 4 includes a stirring shaft 402 that is movably clamped and installed above the inner wall of the feeding cylinder 3. This installation method not only ensures the flexible rotation of the stirring shaft 402 but also ensures its stability. Above the stirring shaft 402, a stirring bevel gear 401 is fixedly installed. When the transmission device 5 drives the stirring bevel gear 401 to rotate, the stirring shaft 402 rotates accordingly. On the surface of the stirring shaft 402, a number of stirring rings 403 are evenly installed. On the side of the stirring ring 403, a number of stirring rods 404 are evenly installed. The multi-angle and multi-level stirring structure can fully stir and mix the raw materials in the feeding cylinder 3, ensuring the uniform mixing of the raw materials of the aerogel coating, guaranteeing the product quality, and preventing crystallization. On the lower surface of the stirring shaft 402, a positioning rod 405 is movably installed, which plays a role in assisting positioning and stabilizing the stirring shaft 402. Below the stirring shaft 402, a threaded rod 406 is fixedly installed for the subsequent feeding process. Below the stirring device 4, a cleaning device 6 is fixedly installed. The cleaning device 6 can synchronously clean the cylinder wall during the stirring process. The cleaning device 6 includes a cleaning ring 601 fixedly installed on the surface of the stirring shaft 402. On the surface of the cleaning ring 601, cleaning rods 602 are evenly installed. One end of the cleaning rod 602 is fixedly installed with a vertical rod 603, and the vertical rod 603 is adaptively in contact with the inner wall of the feeding cylinder 3. When the stirring shaft 402 rotates, the cleaning device 6 operates synchronously, and the cleaning rods 602 and the vertical rods 603 clean the inner wall of the feeding cylinder 3 to prevent raw materials from adhering to the cylinder wall and affecting the next production. Above the support plate 1, a transmission device 5 is fixedly installed. The transmission device 5 includes a transmission fan 501 fixedly installed above the support plate 1. At the output end of the transmission fan 501, a first transmission gear 502 is fixedly installed. On the surface of the first transmission gear 502, a transmission belt 503 is adaptively installed to achieve power transmission through the transmission belt 503. The other end of the transmission belt 503 is adaptively installed with a second transmission gear 504. On one side of the second transmission gear 504, a transmission rod 505 is fixedly installed. On the surface of the transmission rod 505, a transmission sleeve 506 is movably installed. Below the transmission sleeve 506, a transmission plate 507 is fixedly installed. The transmission plate 507 is fixedly installed on the surface of the feeding cylinder 3. The transmission sleeve 506 plays a role in supporting and positioning the transmission rod 505. On the other end surface of the transmission rod 505, a transmission bevel gear 508 is fixedly installed. The transmission bevel gear 508 meshes with the stirring bevel gear 401, thereby driving the stirring device 4 to work. At one end of the transmission device 5, a feeding device 7 is fixedly installed. The feeding device 7 is responsible for sending out the stirred coating.The feeding device 7 includes a feeding pipe 701 fixedly installed at the air outlet end of the driving fan 501. Above the feeding pipe 701, a material conveying pipe 702 is fixedly installed. The inner wall of the material conveying pipe 702 is adapted to the threaded rod 406. One end of the feeding pipe 701 is fixedly installed with a switch 703. An electromagnetic valve 704 is fixedly installed on the inner wall of the feeding pipe 701. A dust-proof net 705 is fixedly installed on the inner wall of the feeding pipe 701. The dust-proof net 705 prevents impurities from entering the feeding pipe 701 and ensures the quality of the conveyed paint. After the stirring is completed, the stirring shaft 402 drives the threaded rod 406 to rotate in the material conveying pipe 702, and the raw materials in the feeding cylinder 3 are transmitted into the feeding pipe 701 through the threads on the surface. One end of the feeding pipe 701 is fixedly installed with a switch 703 for controlling the start and stop of feeding. Above the inner wall of the feeding cylinder 3, a cleaning device 8 is fixedly installed. The cleaning device 8 includes a cleaning pump 801 fixedly installed above the inner wall of the feeding cylinder 3. An inlet 802 is installed above the cleaning pump 801. The water outlet end of the cleaning pump 801 is fixedly installed with a distribution pipe 803. The distribution pipe 803 is inclined 30 degrees towards the inner wall of the feeding cylinder 3. A protective cover 9 is fixedly installed above the feeding cylinder 3; During use, first turn on the control device. The operator opens the switch 703 at one end of the feeding pipe 701 and at the same time uses the control device to control the electromagnetic valve 704 to open to prepare for subsequent feeding. Then start the driving fan 501. The driving fan 501 serves as a power source, and its output end drives the first driving gear 502 to rotate at a high speed. At the same time, it can generate wind power, and this part of the wind power plays a role in the subsequent feeding process; The first driving gear 502 transmits power to the second driving gear 504 through the transmission belt 503, causing the second driving gear 504 to rotate, and then driving the transmission rod 505 to rotate. The transmission bevel gear 508 at the other end of the transmission rod 505 meshes tightly with the stirring bevel gear 401 in the stirring device 4, thereby driving the stirring shaft 402 to start rotating. The stirring rings 403 and stirring rods 404 on the surface of the stirring shaft 402 mix the raw materials in the feeding cylinder 3 in all directions to prevent crystallization caused by long-term accumulation. At the same time, since the cleaning ring 601 of the cleaning device 6 is fixedly installed on the surface of the stirring shaft 402, as the stirring shaft 402 rotates, the cleaning rods 602 and vertical rods 603 on the surface of the cleaning ring 601 synchronously clean the inner wall of the feeding cylinder 3 to ensure that there is no raw material residue on the cylinder wall and it is not affected by the raw materials remaining from the previous time; During the stirring process, the threaded rod 406 below the stirring shaft 402 also plays a role. Since the inner wall of the material conveying pipe 702 is adapted to the threaded rod 406, as the stirring shaft 402 continues to rotate, the threaded rod 406 rotates within the material conveying pipe 702, and gradually pushes the stirred raw materials in the feeding cylinder 3 into the feeding pipe 701 through the threads on its surface. At this time, the wind force generated by the driving fan 501 acts on the feeding pipe 701, quickly transporting the aerogel coating in the feeding pipe 701. In this process, since the operating frequency of the driving fan 501 simultaneously affects the transmission speed of the threaded rod 406 of the stirring device and the generation of wind force, it is satisfied that when the rotational speed of the driving fan 501 increases and the conveying speed of the threaded rod 406 for the material increases, the wind force also increases simultaneously, enabling the coating to be transported faster; when the rotational speed of the driving fan 501 decreases, the conveying speed of the threaded rod 406 for the material slows down, saving energy, and realizing the synchronous control of the raw material flow rate and the conveying speed of the material. The dust-proof net 705 in the feeding pipe 701 always plays a role to prevent raw materials from entering the feeding pipe 701 and ensure the quality of the transported coating; When all the feeding work is completed, it enters the cleaning link. The operator uses the control device to close the solenoid valve 704 again, connects a water source to the water inlet 802 above the cleaning pump 801, and then starts the cleaning pump 801. The cleaning pump 801 pressurizes the water and sprays it out through the distribution pipe 803. Since the distribution pipe 803 is inclined 30 degrees towards the inner wall of the feeding cylinder 3, the water can evenly wash the inner wall of the feeding cylinder 3. The cleaned sewage drains to the feeding pipe 701 through the feeding port in the middle of the conical plate 301 below the feeding cylinder 3 by gravity and finally discharges from the equipment. At the same time, the driving fan 501 can be operated to drive the stirring device 4 and the cleaning device 6 to operate, so that the cleaning device 6 cleans and scrapes the inner wall of the tank body to ensure that the device remains clean after the work is completed and prepares for the next production.

[0019] Embodiment 2: Please refer to Figures 1-4 , a technical solution provided by the present invention: A conveying method for a feeding device for producing aerogel coatings, comprising the following steps: S1: Add the raw materials required for producing aerogel coatings to the feeding port 302 above the feeding cylinder 3, open the switch 703 at one end of the feeding pipe 701, and simultaneously use the control device to control the solenoid valve 704 to open; S2: Start the drive fan 501. The output end of the drive fan 501 drives the first drive gear 502 to rotate. The first drive gear 502 drives the second drive gear 504 to rotate through the drive belt 503, thereby causing the drive rod 505 to rotate. The drive bevel gear 508 at the other end of the drive rod 505 meshes with the stirring bevel gear 401 to drive the stirring shaft 402 to rotate. The stirring rings 403 and stirring rods 404 on the surface of the stirring shaft 402 stir and mix the raw materials in the feeding cylinder 3. At the same time, the cleaning device 6 fixed below the stirring shaft 402 rotates with the stirring shaft 402. The cleaning rods 602 and vertical rods 603 on the surface of the cleaning ring 601 clean the inner wall of the feeding cylinder 3 to prevent raw materials from adhering to the cylinder wall; S3: During the stirring process, since the stirring shaft 402 rotates under the action of force, it drives the lower threaded rod 406 to rotate in the material conveying pipe 702. When the threaded rod 406 rotates, the raw materials in the feeding cylinder 3 are transported into the feeding pipe 701 through the threads on its surface. At the same time, the drive fan 501 operates to generate wind power, and the stirred aerogel coating is transported out through the feeding pipe 701. The dust-proof net 705 in the feeding pipe 701 can prevent raw materials from entering the feeding pipe 701 and ensure the quality of the transported coating; S4: When the feeding work is completed, the feeding cylinder 3 needs to be cleaned. At this time, use the control device to close the solenoid valve 704, connect water to the water inlet 802 above the cleaning pump 801, and start the cleaning pump 801. The cleaning pump 801 sprays water through the distribution pipe 803. The distribution pipe 803 is inclined 30 degrees towards the inner wall of the feeding cylinder 3 so that the water can evenly wash the inner wall of the feeding cylinder 3. The sewage after cleaning is discharged from the feeding port in the middle of the conical plate 301 below the feeding cylinder 3 into the feeding pipe 701 and the waste water is discharged. At the same time, repeat S2 during the spraying process to ensure the cleanliness of the inner wall of the feeding cylinder 3 and prevent adhesion to the inner wall from affecting subsequent use.
