Description

Technical Field

[0001] The utility model relates to the technical field of cyclone pulverizers, in particular to a feeding mechanism of a cyclone pulverizer. Background Art

[0002] The crushing device of solid materials plays a very wide role in our daily life and work. People have conducted a lot of exploration on the crushing devices of various solid materials and proposed various different grinding methods, such as rod mill, ball mill, roller mill, Raymond mill, etc. Due to the different physical properties of various solid materials, their effects are also very different.

[0003] In order to improve the crushing effect, the cyclone mill in the prior art usually allows the raw materials to be crushed to fall evenly into the mill through a shower-type feeding device. For example, the Chinese patent application number: 202123048545.4 discloses a cyclone mill belonging to the field of pulverizer technology, including a drive pulley, a bearing seat device, a rotor main shaft, a rotor small blade disc, a rotor large blade disc, a shower-type feeding device, a machine cover, and a machine base; the number of shower-type feeding devices is two symmetrically distributed on the outside of the rotor main shaft. The utility model has the characteristics of compactness, simplicity, excellent performance, safety and reliability. The cantilever rotor crushing capacity is optimized and controlled, and the operation is smooth. The crushing efficiency is higher through the large and small knife disc structure configuration based on the silicon work hardening characteristics and the golden rule. The crushing effect is optimized and the service life is longer through the tool configuration based on the silicon mechanical properties and deformation characteristics. The rain-type feeding device controlled by the bend diversion and silicon single particle crushing principle has a high collision dispersion rate, which is beneficial to improving the yield of one-time crushing, increasing the production capacity of the whole machine and various performance indicators, and the flat bottom of the discharge port at the bottom of the machine further improves the safety.

[0004] Although the shower-type feeding device in the above-mentioned patent is arranged in an inclined shape and can form a certain angle with the crusher (i.e., form a corner), the raw materials are scattered by collision at the corner position during feeding, and are fed in a waterfall-like manner. However, since there is only one corner in the feeding diagram of the shower-type feeding device in the prior art, the raw material dispersion effect is not good, and there is a lack of raw material dispersion structure at the connection with the crusher, which makes it inconvenient to disperse the dispersed raw materials again, resulting in the final shower-type feeding effect being poor. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a feeding mechanism for a cyclone pulverizer.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a feeding mechanism of a cyclone mill, comprising a cyclone mill body, at least one group of feeding channels are arranged on the top of the cyclone mill body, and feeding channels are arranged above the feeding channels. The feeding channels are arranged in an inclined shape, and the upper ends of the feeding channels are connected to the feeding channels, and the inclination directions of the feeding channels are different from those of the feeding channels.

[0007] As a further description of the above technical solution: each group of the feed channels includes a high feed pipe and a low feed pipe, and the high feed pipe and the low feed pipe are fixedly installed on the cyclone mill body and are connected to the inner cavity of the cyclone mill body.

[0008] As a further description of the above technical solution: the feeding channel includes a long feeding channel and a short feeding channel, a feed plate is arranged between the long feeding channel and the short feeding channel, the feed plate separates the long feeding channel and the short feeding channel, the long feeding channel is fixedly connected to the low feeding pipe, and the short feeding channel is fixedly connected to the high feeding pipe.

[0016] The utility model has the following beneficial effects:

[0017] Compared with the prior art, the feeding mechanism of the cyclone mill, when adding the raw materials to be crushed into the cyclone mill body through the feeding channel and the feeding channel, since the feeding channel is arranged in an inclined shape and has a certain angle with the feeding channel, a first small turning angle is formed by this design. When the raw materials pass through the position of the small turning angle, the raw materials collide and disperse. Moreover, since the feeding channel is also arranged in an inclined shape, there is also a certain angle between it and the cyclone mill body. Therefore, a second small turning angle can be formed by this design. When the raw materials pass through the position of the small turning angle, the raw materials can collide and disperse again. Through the two collisions and dispersions of the raw materials during the feeding process, concentrated feeding of the raw materials can be avoided, so as to realize waterfall-like feeding, which is beneficial to the subsequent cyclone mill body to efficiently crush the raw materials and has a high crushing yield.

[0018] Compared with the prior art, the feeding mechanism of the cyclone mill, through the setting of a grid dispersion rack or an elastic rocker arm, can, during feeding, allow the raw materials, after two collisions and dispersions, to collide and disperse again with the grid dispersion rack during the process of entering the cyclone mill body, thereby further improving the dispersion effect of the raw materials and ensuring that the raw materials are fed in a waterfall-like manner.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0029] As attached Figure 1 To Attachment Figure 4 As shown, the utility model provides a feeding mechanism of a cyclone mill, comprising a cyclone mill body 1, wherein two groups of feeding channels are arranged on the top of the cyclone mill body 1, and feeding channels are arranged above the two groups of feeding channels, wherein the feeding channels are arranged in an inclined shape, and the upper ends of the feeding channels are connected to the feeding channels, and the inclination directions of the feeding channels are different from those of the feeding channels.

[0030] The feeding channel is provided with an observation port 9, and the observation port 9 is provided with a sealing plate 10. The setting of the observation port 9 facilitates the staff to observe the feeding amount.

[0031] Each group of the feed channels includes a high feed pipe 3 and a low feed pipe 4, the high feed pipe 3 and the low feed pipe 4 are fixedly mounted on the cyclone mill body 1 and are connected to the inner cavity of the cyclone mill body 1, the feed channels include a long feed channel 5 and a short feed channel 6, a prying plate 7 is provided between the long feed channel 5 and the short feed channel 6, the prying plate 7 separates the long feed channel 5 and the short feed channel 6, the long feed channel 5 is fixedly connected to the low feed pipe 4, the short feed channel 6 is fixedly connected to the high feed pipe 3, and the high feed pipe 3 and the low feed pipe 4 are both arranged in an inclined shape;

[0032] A grid dispersion rack 2 is provided at the connection between the feed channel and the cyclone mill body 1. Through the setting of the grid dispersion rack 2, when feeding, the raw materials after two collision dispersions will collide and disperse with the grid dispersion rack 2 again in the process of entering the cyclone mill body 1, thereby further improving the dispersion effect of the raw materials and ensuring that the raw materials are fed in a waterfall shape.

[0033] Working principle: when adding the raw material to be crushed into the cyclone mill body 1 through the feeding channel and the feed channel, since the feeding channel is arranged in an inclined shape and has a certain angle with the feed channel, the first small angle is formed by this design. When the raw material passes through the position of the small angle, the raw material collides and disperses. Since the feed channel is also arranged in an inclined shape, there is also a certain angle between it and the cyclone mill body 1. Through this design, a second small angle can be formed. When the raw material passes through the position of the small angle, the raw material can collide and disperse again. Through the two collisions and dispersions of the raw materials during the feeding process, concentrated feeding of the raw materials can be avoided, so as to realize waterfall-like feeding, which is beneficial to the subsequent cyclone mill body 1 to efficiently crush the raw materials and have a high crushing yield. Example

[0034] As attached Figure 5 and attached Figure 6 As shown, this embodiment is basically the same as the first embodiment, except that the high feed pipe 3 is vertically arranged, the low feed pipe 4 is inclined, the high feed pipe 3 is fixedly connected to a staggered square box 8, and the high feed pipes 3 located above and below the staggered square box 8 are staggered.

[0035] The principle is: when the raw material passes through the high feed pipe 3, since the high feed pipes 3 located above and below the offset square box 8 are staggered, there is a corner when the raw material passes through the offset square box 8, and the raw material collides with the inner wall of the offset square box 8 to disperse. Example

[0036] As attached Figure 7 As shown, this embodiment is basically the same as the first embodiment, except that an elastic rocker arm 11 is provided at the connection between the feed channel and the cyclone mill body 1, and the elastic rocker arm 11 can be a flexible rod or a rod having one end rotatably connected to the inner wall of the feed channel through a torsion spring.

[0037] In order to improve the effect, a plurality of elastic rocker rods 11 can be provided, and the plurality of elastic rocker rods 11 are evenly distributed around the axial direction of the feed channel.

[0038] The principle is: when the raw materials to be crushed fall and contact, they deform and bend or swing around the rotating connection point. On the one hand, the raw materials to be crushed can be dispersed when they fall on the elastic swing rod 11. On the other hand, after the raw materials to be crushed pass through, the elastic swing rod 11 will elastically reset, forming a slapping effect on the subsequent raw materials to be crushed.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
