Description

Technical Field

[0001] The utility model relates to a material mixing device, specifically to a powder material dispersion feeding device. Background Art

[0002] The applicant disclosed an air purification ball, a preparation method thereof and an air purifier in the patent with the application number 201811102363.0. Among them, the air purification ball is made by mixing powder materials such as hydrated lime powder, heavy calcium powder, zeolite powder, tourmaline powder, talc powder, white cement, barite, diatomite, etc., and then made into small balls. The functional materials added to the product can continuously release negative oxygen ions into the air, playing the role of purifying the air. Therefore, the applicant also calls it a negative oxygen ion ball.

[0003] When preparing the above-mentioned negative oxygen ion ball, various powder materials need to be mixed together and then mixed evenly with a little water for subsequent granulation. In order to make the water-powder mixture more uniform and the ball shape more uniform, the applicant designed a device that uses the rising swirl flow in the swirl channel to drive the powder materials to disperse and spray atomized water on the dispersed powder materials to achieve the water-powder mixture. Among them, the uniformity of powder material dispersion will affect the uniformity of the final water-powder mixture, and the uniformity of powder material feeding will affect the subsequent dispersion effect. However, there is no device in the existing equipment that can evenly feed the above-mentioned swirl channel.

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

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, and thus provide a powder material dispersion feeding device that can feed into the swirl channel in multiple directions, and improve the uniformity of powder material feeding by controlling the balance of feeding in each direction.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a powder material dispersion feeding device, including a total feeding hopper, a conical diverging port, a conical distributor and a number of distributing pipes evenly arranged in a circle. The top of the conical diverging port is connected to the output end of the total feeding hopper. The conical distributor is coaxially arranged in the center of the conical diverging port, and there is a material dispersion gap between the conical distributor and the conical diverging port. The top input ends of a number of the distributing pipes converge and are connected to the bottom of the conical diverging port. The middle parts of a number of the distributing pipes are bent outwards, and the bottom output ends of a number of the distributing pipes are bent towards the center.

[0007] Based on the above, the material distribution pipe includes an outwardly inclined section, a vertical section, an inwardly inclined section, and an upwardly folded section that are sequentially connected from the top input end to the bottom output end. The outwardly inclined section is inclined downward toward the periphery, the inwardly inclined section is inclined downward toward the center, and the upwardly folded section is inclined upward toward the center.

[0008] Based on the above, high-pressure air pipes are respectively arranged on the pipe walls at the incoming material ends of several of the inwardly inclined sections to blow the material out from the bottom output end of the material distribution pipe.

[0009] Based on the above, four of the material distribution pipes are provided in total.

[0010] Based on the above, a pneumatic hammer is installed on the outer wall of the conical material distribution opening.

[0011] The utility model has substantial features and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0012] (1) The total feed hopper is used to input powdery materials. The conical distributor guides the powdery materials to evenly disperse into several of the material distribution pipes through the material dispersion gap. The bottom output end of the material distribution pipe is used to feed the swirling channel from multiple directions, thereby improving the uniformity of feeding.

[0013] (2) The setting of the upwardly folded section provides an initial upward force for the powdery materials. The setting of the high-pressure air pipes can increase the initial power of the powdery materials, facilitating the swirling in the swirling channel to lift up.

[0014] (3) The setting of the pneumatic hammer can avoid the blockage of the powdery materials through intermittent vibration, making the feeding smoother. Description of the Drawings

[0018] The following further describes the technical solutions of the utility model in detail through specific embodiments.

[0019] Such as Figure 1 and Figure 2As shown in the figure, a powder material dispersion feeding device includes a total feeding hopper 1, a conical diverging port 2, a conical distributor 3, and four evenly distributed feeding pipes 4 arranged in a circle (the feeding pipe at the back in the figure is blocked by the feeding pipe in the front). The top of the conical diverging port 2 is connected to the output end of the total feeding hopper 1. The conical distributor 3 is coaxially arranged in the center of the conical diverging port 2, and a material dispersion gap 5 is left between the conical distributor 3 and the conical diverging port 2. The top input ends of the four feeding pipes 4 converge and are connected to the bottom of the conical diverging port 2. The middle parts of the four feeding pipes 4 bend outward, and the bottom output ends of the four feeding pipes 4 bend towards the center to convey powder materials to the central swirling channel 8.

[0020] Specifically, the feeding pipe 4 includes an outward-inclined section 41, a vertical section 42, an inward-inclined section 43, and an upward-folded section 44 connected in sequence from the top input end to the bottom output end. The outward-inclined section 41 inclines downward towards the periphery, the inward-inclined section 43 inclines downward towards the center, the upward-folded section 44 inclines upward towards the center. High-pressure air pipes 6 are respectively arranged on the incoming material end walls of the inward-inclined section 43 to blow the materials out from the bottom output end of the feeding pipe 4.

[0021] Working principle:

[0022] The bottom output ends of the four feeding pipes 4 are connected to the bottom of the swirling channel 8 from four directions. The total feeding hopper 1 is used to input powder materials. The conical distributor 3 guides the powder materials to evenly disperse into the four feeding pipes 4 from the material dispersion gap 5. The bottom output ends of the feeding pipes 4 feed the swirling channel 8 from four directions, thereby improving the feeding uniformity. The setting of the upward-folded section 44 provides an initial upward force for the powder materials, and the high-pressure air pipes 6 can increase the initial power of the powder materials, facilitating the powder materials to be carried up by the swirl in the swirling channel 8.

[0023] In order to avoid blockage during material feeding, a pneumatic hammer 7 is installed on the outer wall of the conical diverging port 2. During use, through intermittent knocking, the conical diverging port 2 is vibrated to avoid powder materials from forming blockages and make the feeding smoother.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features.
