Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a ball mill with a dust collecting function for producing bone china tableware. Background Art

[0002] A ball mill consists of a horizontal, slowly rotating cylinder filled with spherical grinding media (steel balls, zirconia balls, alumina balls, pebbles, or porcelain balls). Based on the discharge method, they are classified into overflow, grid, and peripheral types; based on the cylinder shape, they are classified into cylindrical, conical, and polygonal types; and based on the ratio of length to diameter, they are classified into short-cylinder, long-cylinder, and tube mills. They have the advantages of simple structure and strong adaptability, and are primarily used in the production of cement, silicate products, new building materials, refractories, fertilizers, ferrous and non-ferrous metal beneficiation, and glass and ceramics.

[0003] Bone china tableware is a kind of porcelain dining utensil made from animal bone charcoal, clay, feldspar and quartz as basic raw materials. It is fired twice, high-temperature bisque firing and low-temperature glaze firing. Before making bone china tableware, the above raw materials need to be ground into powder using a ball mill.

[0004] Existing ball mills often use two methods of dust removal: negative pressure dust removal and spray dust removal when performing dry grinding. Among them, in the negative pressure dust removal method, after long-term use, dust accumulation is likely to occur due to the increase in collected dust, resulting in a decrease in negative pressure, resulting in poor subsequent dust collection effect.

DETAILED DESCRIPTION

[0036] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0037] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0038] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0039] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0040] Reference Figures 1 to 6 , which is the first embodiment of the utility model, proposes a ball mill for producing bone china tableware with a dust collection function, including a ball mill body 1 and a dust collection device 2. The dust collection device 2 is used to collect dust discharged from the outlet end of the ball mill body 1. The dust collection device 2 includes: an ash absorption plate 201, which is arranged on the outlet end and has a cavity 2011; a collection barrel 202, which has an ash collection cavity 210, and the cavity 2011 is connected to the ash collection cavity 210; a scraper 206, which is arranged in the collection barrel 202, and the scraper 206 is in sliding contact with the inner wall of the collection barrel 202. The scraper 206 has a collection groove 2063, and the collection groove 2063 is connected to the ash collection cavity 210.

[0041] In the above scheme, during production, the raw materials and steel balls required for producing bone china tableware are loaded into the ball mill from the inlet. After grinding, the raw materials flow out of the outlet, and the generated dust is promptly sucked in by the dust absorption plate 201. It should be noted that the dust absorption plate 201 is installed outside the outlet, which not only does not affect the discharge of the material at the outlet, but also promptly absorbs the generated dust into the cavity 2011. Secondly, to improve the dust removal effect, the dust absorption plate 201 can also be arranged at an angle. The arrangement of the dust absorption plate 201 is determined by actual usage. In addition, the ash collection chamber 210 of the collection tube 202 is a cylindrical cavity, and the scraper 206 is used to scrape away dust adhering to its side walls.

[0042] This device is used to collect dust at the outlet end of the ball mill. The dust is absorbed by the dust absorption plate 201 and then transported to the collection barrel 202. The scraper 206 in the collection barrel 202 rotates along the center of the collection barrel 202. While rotating, it not only collects the dust inside the collection barrel 202 into the collection groove 2063, but also collects the dust adhering to the inner wall of the collection barrel 202, which is conducive to collecting most of the dust into the collection groove 2063, preventing a large amount of dust from accumulating after a long period of dust collection and affecting the subsequent dust collection work. Therefore, the dust collection device 2 can work for a long time, thereby improving the cleanliness of the ball mill when grinding the raw materials required for bone porcelain.

[0043] Furthermore, it also includes: a central filter cartridge 205, which is rotatably arranged in the collecting cartridge 202, the central filter cartridge 205 and the collecting cartridge 202 are arranged coaxially, and a collecting channel is formed between the outer wall of the central filter cartridge 205 and the inner wall of the collecting cartridge 202; there are a plurality of scrapers 206, and the scrapers 206 are all located in the collecting channel, and the scrapers 206 are centered on the central filter cartridge 205 and are arranged in the collecting channel in a ring-shaped manner.

[0044] In the above scheme, the sidewall of the central filter cartridge 205 is provided with a number of circular through-holes. During dust collection, the central filter cartridge 205 rotates at high speed. Dust entering the central filter cartridge 205 flows from the circular through-holes of the central filter cartridge 205 into the collection channel under centrifugal force and negative pressure. At this time, the scraper 206 collects the dust in the collection channel and stores it in the collection trough 2063. Therefore, the function of the central filter cartridge 205 can be understood as "distributing dust into the collection channel." Since the scraper 206 moves along the collection channel, the dust in the collection channel is collected by the collection trough 2063 of the scraper 206. Secondly, to improve the dust collection efficiency of the collection trough 2063 of the scraper 206, a filter screen can be installed on the collection trough 2063.

[0045] Furthermore, it also includes: a driver 207, which is arranged at the bottom of the collecting barrel 202; a planetary gear mechanism 209, which is arranged at the bottom of the collecting barrel 202, the planetary gear mechanism 209 has a sun gear 2091 and a planetary gear 2092, the central filter barrel 205 is fixedly connected to the sun gear 2091, and the planetary gear 2092 is rotationally connected to the scraper 206; an outer ring gear, which is arranged at the bottom of the collecting barrel 202, and the planetary gear 2092 is transmission-connected to the outer ring gear; the driver 207 is used to drive the sun gear 2091 to rotate.

[0046] In the above embodiment, driver 207 is located at the bottom of collection tube 202. Driver 207 includes a chassis and a motor. The chassis serves as a base 208 for collection tube 202. The motor's output shaft extends through the top of the chassis and the bottom of collection tube 202, and is connected to sun gear 2091. When the motor outputs power, it drives sun gear 2091 to rotate, which in turn drives central filter tube 205. The number of planetary gears 2092 is the same as the number of scrapers 206. Scrapers 206 are rotationally connected to the planetary gears 2092, so rotation of the planetary gears 2092 does not cause rotation of the scrapers 206.

[0047] Furthermore, it also includes: a base 208, which is arranged in the collecting tube 202, and is used to shield the planetary gear mechanism 209; the bottom surface of the scraper 206 is in sliding contact with the upper surface of the base 208.

[0048] In the above scheme, the base 208 is installed in the collecting cylinder 202, and the space between the bottom surface of the base 208 and the bottom surface of the collecting cylinder 202 is used to place the planetary gear mechanism 209. It should be noted that a number of through holes are opened on the base 208 for the scraper 206 and the central filter cartridge 205 to pass through, so as to facilitate the connection between the scraper 206, the central filter cartridge 205 and the planetary gear mechanism 209.

[0049] Furthermore, the scraper 206 includes: a connecting frame 2061, which is arranged in the collection channel, and the bottom end of the connecting frame 2061 passes through the base 208 and is rotatably connected to the planetary gear 2092; a vertical plate 2062, which is arranged on the connecting frame 2061, and the collection trough 2063 is opened in the vertical plate 2062.

[0050] In the above scheme, the connecting frame 2061 includes a vertical rod and a clamping plate. The vertical rod is arranged along the circumferential direction of the collecting cylinder 202, and the vertical rod is rotationally connected to the planetary wheel 2092. It should be noted that when the planetary wheel 2092 rotates, although the vertical rod and the planetary wheel 2092 are rotationally connected, the planetary wheel 2092 will still affect the vertical rod and drive the vertical rod to deflect slightly. At this time, under the influence of the planetary wheel 2092, the vertical rod will drive the vertical plate 2062 to deflect, so that the vertical plate 2062 is tightly against the side wall of the collecting cylinder 202, and the side wall of the collecting cylinder 202 is scraped.

[0051] Furthermore, it also includes: a conveying pipe 203, one end of which is connected to the cavity 2011 and the other end is connected to the ash collecting chamber 210. The conveying pipe 203 is located at one end of the ash collecting chamber 210 and extends into the central filter cartridge 205.

[0052] In the above solution, the delivery tube 203 connects the collection drum 202 and the dust collecting plate 201. The length and bending angle of the delivery tube 203 can be determined based on actual usage. It should be noted that the collection drum 202 should not affect the discharge of the material at the outlet. Furthermore, the delivery tube 203 can also be a corrugated hose to further facilitate the repositioning of the collection drum 202.

[0053] Furthermore, it also includes: a negative pressure generator 204, which is arranged on the collection tube 202 and is used to provide a negative pressure environment for the collection tube 202. The negative pressure generator 204 includes one or more fans. It is understood that since the negative pressure generator 204 is installed at the top of the collection tube, the delivery pipe 203 at one end of the collection tube 202 should extend to one-third of the height of the central filter tube 205 (the direction from the base 208 to the negative pressure generator 204 is the height direction). When dust enters the central filter tube 205 from the air delivery pipe, the dust will enter the central filter tube 205 under the action of negative pressure. Due to the negative pressure and the centrifugal effect of the central filter tube 205, the dust will flow diagonally upward from the central filter tube 205. At this time, the dust flowing out of the central filter tube 205 will be collected by the collection groove 2063 of the scraper 206. It should be noted that the central filter tube 205 and the scraper 206 of this device both rotate at high speed.

[0054] Furthermore, the dust absorption plate 201 is arc-shaped, and a plurality of dust inlet holes 2012 are provided on the inner wall of the dust absorption plate 201. The dust inlet holes 2012 are provided on the arc-shaped inner wall of the arc-shaped dust absorption plate 201 to achieve semi-enclosed protection.

[0055] Furthermore, it also includes: a connecting rod 3, one end of which is arranged on the ball mill body 1, and the other end is arranged on the dust absorption plate 201. The length of the connecting rod 3 and the deflection angle of the connecting rod 3 can be set by yourself.

[0056] 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 the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
