Description

Technical Field

[0001] The present invention relates to the technical field of environmentally friendly building materials, and in particular to a negative oxygen ion ball production device and a production method. Background Art

[0002] Patent application number 201811102363.0 discloses an air purification ball, a preparation method of an air purification ball, and an air purifier. The air purification ball is made by mixing powders such as lime calcium powder, heavy calcium powder, zeolite powder, tourmaline powder, talcum powder, white cement, barite, diatomaceous earth, etc., and then prepared into small balls. The functional materials added to the product can continuously release negative oxygen ions into the air, playing a role in refreshing the air, so the applicant also calls it a negative oxygen ion ball.

[0003] The preparation of the above-mentioned negative oxygen ion balls includes the steps of weighing the raw materials, adding water and stirring, granulating into balls, and drying. Among them, the existing production equipment uses a drum granulator for granulation. The main structure of the drum granulator is a horizontal cylinder. When in use, the weighed powder is put into the horizontal cylinder. The high-speed rotation of the horizontal cylinder is used to make the powder tumble in the cylinder. At the same time, a nozzle is used to spray water into the horizontal cylinder to mix the powder and water. As the horizontal cylinder rotates, stirring and bonding are achieved to complete the granulation. On the one hand, this granulation method is easy to cause uneven mixing of water and powder because the powder is close to the cylinder wall when tumbling in the horizontal cylinder. On the other hand, the inner wall of the horizontal cylinder is cylindrical. During the rolling granulation process, the powder close to the inner wall and the powder far from the inner wall are subjected to uneven force, and the tumbling effect is not good. As a result, when the granulated particles are finally rolled into balls, the size of the granulated particles is uneven and the shape is very irregular.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0018] The present invention also provides a method for producing negative oxygen ion balls, which is produced using the negative oxygen ion ball production device described above, and comprises the following steps:

[0019] (1) By weight, 10-20 parts of lime lime powder, 10-20 parts of heavy calcium powder, 20-35 parts of admixture, 10-15 parts of white cement, 5-15 parts of talc, 5-10 parts of diatomaceous earth, 5-15 parts of barite, and 3-5 parts of admixture are mixed uniformly to obtain a powdered raw material; wherein the admixture is prepared by mixing zeolite powder and tourmaline powder in a ratio of 5:1, and the admixture is prepared by mixing cellulose and redispersible latex powder in a ratio of 1:4;

[0020] (2) feeding the powdered raw materials uniformly mixed according to the above formula ratio into the main feed hopper, dispersing them through the conical distributor, and evenly entering the plurality of distribution pipes;

[0021] (3) The volute-shaped exhaust port draws air, causing negative pressure to be generated in the swirl channel. The air inlet channel draws air into the swirl channel, and after entering from the bottom of the air inlet channel, an ascending swirl is formed in the swirl channel;

[0022] (4) The plurality of distribution pipes spray the powdered raw materials from multiple angles toward the outer wall of the inner cylinder and splash them in all directions. The rising vortex drives the powdered raw materials to rise together and diffuse them into the vortex channel;

[0023] (5) A plurality of atomizing nozzles spray atomized water vapor into the swirl channel to mix with the diffused powdered raw materials. The weight of the wetted powdered raw materials increases and falls back into the buffer silo for temporary storage;

[0024] (6) The exhaust pipe draws air to generate negative pressure in the horizontal cylinder, and the wet powder in the buffer silo is drawn into the horizontal cylinder through the wet powder feeding pipe;

[0025] (7) The driving mechanism drives the horizontal cylinder to roll. During the rolling process, the wavy inner wall periodically squeezes the wet powder from different angles, and finally prepares negative oxygen ion balls.

[0026] The present invention has outstanding substantial features and significant progress compared to the prior art. Specifically, the present invention has the following advantages:

[0027] (1) The powder dispersing and feeding device utilizes the conical distributor to evenly disperse the powdered raw materials into the plurality of the distribution pipes, and enters the vortex channel from multiple angles, thereby ensuring uniform feeding; the air is drawn through the volute-shaped exhaust port, so that the wind passes through the bottom end of the inner cylinder, the vortex channel and the volute-shaped exhaust port in sequence, forming an ascending vortex in the vortex channel, and the powdered raw materials input from the distribution pipe are brought up and diffused into the vortex channel, and then a plurality of the atomizing nozzles are used to spray atomized water vapor, so that the powder and the water vapor are evenly mixed; the weight of the wetted powder increases, and after falling back into the buffer silo for temporary storage, it enters the horizontal cylinder and begins to roll through the horizontal cylinder. The wavy inner wall can squeeze it from different angles, and the undulating inner wall can enhance the rolling effect of the wet powder, making the force more uniform and the squeezing force greater, which is conducive to more uniform and regular ball formation.

[0028] (2) The arrangement of the thin waist section and the outward expansion port can guide the airflow to roll upward. The arrangement of the upward folding section provides an initial upward force for the powder. The arrangement of the high-pressure air pipe can increase the initial power of the powder. After the powdered raw material is sprayed onto the outer wall of the thin waist section from the side, it will be guided to splash obliquely upward; in this way, the powder is more easily carried up by the vortex and spreads more evenly, making the water-powder mixing more uniform.

[0029] (3) The arrangement of the circulating air duct and the circulating fan allows air to circulate within the system. On the one hand, this can make the air pressure more stable, which is conducive to the stable diffusion and uniform mixing of the powder and the atomized water vapor. On the other hand, it can prevent the fan from extracting the powder out of the system, which is conducive to recycling and environmental protection.

[0030] (4) By extracting air through the exhaust pipe, negative pressure can be generated in the horizontal cylinder, which facilitates the wet powder in the buffer silo to be sucked into the cylinder through the wet powder feed pipe. The wet powder feed pipe is installed through the first bearing, and the exhaust pipe is installed through the second bearing. It can remain stationary when the cylinder rotates, which is convenient for connection with external equipment; the air inlet of the exhaust pipe is set to face upward, which can prevent the powder from being sucked into the exhaust pipe.

[0031] (5) The pneumatic hammer can vibrate the conical branching opening and the buffer silo through intermittent knocking, thereby avoiding blockage there and making material discharge smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solution of the present invention is further described in detail below through specific implementation methods. Example 1

[0043] like Figure 1-7 As shown, a negative oxygen ion ball production device includes a powder dispersing device, a water-powder mixing device and a ball forming device.

[0044] The powder dispersing device includes a main feed hopper 1, a conical branching opening 2, a conical distributor 3 and four distribution pipes 4 evenly arranged in a circle. The top of the conical branching opening 2 is connected to the output end of the main feed hopper 1, the conical distributor 3 is coaxially arranged in the center of the conical branching opening 2, and a bulk material gap 5 is left between the conical distributor 3 and the conical branching opening 2; the top input ends of the four distribution pipes 4 converge and are connected to the bottom of the conical branching opening 2.

[0045] The water-powder mixing device includes an outer cylinder 7 and an inner cylinder 8. The top end of the side wall of the outer cylinder 7 is provided with a volute-shaped exhaust port 9, and the bottom end is provided with a buffer silo 10; the inner cylinder 8 is inserted at the central axis of the outer cylinder 7, and the inner cylinder 8 is provided with an air inlet channel 11 along the axial direction. The bottom end of the inner cylinder 8 extends to the middle and lower part of the outer cylinder 7, and a vortex channel 12 is formed between the outer wall of the inner cylinder 8 and the inner wall of the outer cylinder 7; the bottom output ends of the four distribution pipes 4 are all connected to the middle and lower part of the outer cylinder 7 and are evenly distributed on the same cross-section. The output port of the distribution pipe 4 is arranged toward the outer wall of the inner cylinder 8, and six atomizing nozzles 13 (located on the same horizontal plane) are evenly distributed on the outer wall of the inner cylinder 8.

[0046] The ball-forming device includes a horizontal cylinder and a driving mechanism for driving the horizontal cylinder to roll, wherein the driving mechanism can adopt the driving structure of the common drum granulator on the market; the horizontal cylinder specifically includes a cylinder body 17 arranged along the axial direction, a feed cylinder cover 18 installed at one end of the cylinder body 17 and an exhaust cylinder cover 19 installed at the other end of the cylinder body 17; a wavy inner wall 20 is provided in the cylinder body 17, and the wavy inner wall 20 includes peak units 201 and trough units 202 that are alternately arranged and surrounded in a circle, and the cross-sections of the peak units 201 and the cross-sections of the trough units 202 are all circular arcs with equal radius; the feed cylinder cover 18 is provided with a wet powder feed pipe 21 connected to the discharge port of the buffer silo 10, and the exhaust cylinder cover 19 is provided with an exhaust pipe 22.

[0047] Working principle:

[0048] The powder dispersing and feeding device utilizes the conical distributor 3 to evenly disperse the powdered raw materials into the four distribution pipes 4, and enters the vortex channel 12 from multiple angles, ensuring that the powder evenly enters the interior of the outer cylinder 7; the air is extracted through the volute-shaped exhaust port 9, so that the wind passes through the bottom end of the air inlet channel 11, the vortex channel 12 and the volute-shaped exhaust port 9 in sequence, forming an ascending vortex in the vortex channel 12, and the powdered raw materials input by the distribution pipe 4 are brought up and diffused into the vortex channel 12, and then the atomizing nozzle 13 is used to spray atomized water vapor to evenly mix the powder and the water vapor; the weight of the wetted powder increases, and after falling back into the buffer silo 10 for temporary storage, it is drawn into the horizontal cylinder, and the horizontal cylinder begins to roll. The wavy inner wall 20 can squeeze it from different angles, and at the same time, the undulating inner wall can enhance the tumbling effect of the wet powder, making the force more uniform and the extrusion force greater, which is conducive to more uniform and regular ball formation.

[0049] In order to make the water-powder mixing more uniform, the inner cylinder 8 includes a cylindrical section 81, a thin waist section 82 and an outward-expanding port 83 connected in sequence from top to bottom. The outer wall of the thin waist section 82 is an inwardly concave arc, and the curvature gradually increases from the top to the bottom. The outer wall of the outward-expanding port 83 is conical. The shape of the air inlet channel 11 is consistent with the outer shape of the inner cylinder 8; the output port of the distribution pipe 4 is arranged toward the thin waist section 82, and the six atomizing nozzles 13 are evenly distributed on the middle outer wall of the cylindrical section 81.

[0050] The distribution pipe 4 includes an outward-inclined section 41, a vertical section 42, an inward-inclined section 43 and an upper folded section 44 connected in sequence from the top input end to the bottom output end. The outward-inclined section 41 is inclined toward the periphery and downward, the inward-inclined section 43 is inclined toward the center and downward, and the upper folded section 44 is inclined toward the center and upward; the upper half of the outer cylinder 7 is a cylindrical portion 71, and the lower half is an inverted cone portion 72, and the four upper folded sections 44 are all connected to the inverted cone portion 72; high-pressure air pipes 6 are respectively provided on the pipe walls of the inlet ends of the four inward-inclined sections 43 to blow the material out from the bottom output end of the distribution pipe 4.

[0051] During use, the narrow waist section 82 and the outward-expanding port 83 guide the airflow upward. The upward fold 44 provides an initial upward force for the powder. The high-pressure air pipe 6 increases the powder's initial momentum. After the powdered material is sprayed from the side onto the outer wall of the narrow waist section 82, it is directed to splash diagonally upward. This allows the powder to be more easily lifted by the swirling flow and spread more evenly, resulting in a more uniform water-powder mixing.

[0052] To ensure an appropriate swirl path, the length of the cylindrical section 81 is no less than two-thirds of the total length of the inner cylinder 8. In this embodiment, the length of the cylindrical section 81 is approximately five-sevenths of the total length of the inner cylinder 8. To avoid additional space occupied by water supply pipes, a water supply pipe 16 is attached to the inner wall of the air inlet channel 11 to supply water to the six atomizing nozzles 13. The top end of the water supply pipe 16 extends beyond the top of the inner cylinder 8 to facilitate connection to an external water source.

[0053] In order to make the system run more stably, the water-powder mixing device also includes a circulating air duct 14 and a circulating fan 15 installed on the circulating air duct 14. The air inlet end of the circulating air duct 14 is connected to the volute-shaped air outlet 9, and the air outlet end of the circulating air duct 14 is connected to the top of the air inlet channel 11. In this way, the air circulates inside the system, which on the one hand can make the air pressure more stable (in actual use, the air inlet of the high-pressure air pipe 6 can be adjusted to basically balance the air leakage of the system), which is conducive to the stable diffusion and uniform mixing of the powder and the atomized water vapor. On the other hand, it can prevent the fan from extracting the powder out of the system, which is beneficial to recycling and environmental protection.

[0054] A first bearing seat is provided at the center of the feed cylinder cover 18, and the wet powder feed pipe 21 is installed in the first bearing seat through a first bearing 23; a second bearing seat is provided at the center of the vacuum cylinder cover 19, and the vacuum pipe 22 is installed in the second bearing seat through a second bearing 24; in this way, when the cylinder body 17 rotates, the wet powder feed pipe 21 and the vacuum pipe 22 can remain stationary, which is convenient for connection with external equipment.

[0055] In order to prevent the powder from being sucked into the exhaust pipe 22 , the air inlet 25 of the exhaust pipe 22 extends into the inner side of the exhaust cylinder cover 19 and is arranged upward.

[0056] In order to make the material discharge smoother, pneumatic hammers 26 are respectively installed on the outer wall of the conical branching opening 2 and the outer wall of the buffer silo 10. Through intermittent knocking, the conical branching opening 2 and the buffer silo 10 can be vibrated to avoid blockage. Example 2

[0057] A method for producing negative oxygen ion balls, using the negative oxygen ion ball production device in Example 1 for production, comprises the following steps:

[0058] (1) By weight, 10-20 parts of lime lime powder, 10-20 parts of heavy calcium powder, 20-35 parts of admixture, 10-15 parts of white cement, 5-15 parts of talc, 5-10 parts of diatomaceous earth, 5-15 parts of barite, and 3-5 parts of admixture are mixed uniformly to obtain a powdered raw material; wherein the admixture is prepared by mixing zeolite powder and tourmaline powder in a ratio of 5:1, and the admixture is prepared by mixing cellulose and redispersible latex powder in a ratio of 1:4;

[0059] (2) The powdered raw materials mixed evenly according to the above formula ratio are put into the main feed hopper 1, dispersed through the conical distributor 3, and evenly enter the four distribution pipes 4;

[0060] (3) The volute-shaped exhaust port 9 draws air, generating a negative pressure in the swirl channel 12. The air inlet channel 11 draws air into the swirl channel 12. After entering from the bottom of the air inlet channel 11, an ascending swirl is formed in the swirl channel 12.

[0061] (4) The four distribution pipes 4 spray the powdered raw materials from multiple angles toward the outer wall of the inner cylinder 8 and splash them in all directions. The rising vortex drives the powdered raw materials to rise together and diffuse them into the vortex channel 12.

[0062] (5) The atomizing nozzle 13 sprays atomized water vapor into the swirl channel 12 to mix with the diffused powdered raw material. The weight of the wetted powdered raw material increases and falls back into the buffer silo 10 for temporary storage;

[0063] (6) The exhaust pipe 22 exhausts air, thereby generating negative pressure in the horizontal cylinder, and the wet powder in the buffer silo 10 is drawn into the horizontal cylinder through the wet powder feeding pipe 21;

[0064] (77) The driving mechanism drives the horizontal cylinder to roll. During the rolling process, the wavy inner wall 20 periodically squeezes the wet powder from different angles, and finally prepares negative oxygen ion balls.

[0065] like Figure 8 and Figure 9 As shown, after actual production comparison, the negative oxygen ion balls produced by the negative oxygen ion ball production device of the present invention are larger, more uniform in size, and more regular in shape. Compared with traditional negative oxygen ion ball production equipment, the product quality is greatly improved.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for protection of the present invention.

During the rolling process, the wavy inner wall periodically squeezes the wet powder from different angles, and finally prepares negative oxygen ion balls.
