Description

Technical Field

[0001] The utility model belongs to the technical field of ball mill pulping, in particular to a novel pulping basket and a ball mill. Background Art

[0002] At present, the use of intermittent ball mills still accounts for a large part in the ceramic industry. However, with the introduction of relevant policies such as "double carbon", the leading ceramic production companies in the industry have adjusted the ball stones in the intermittent ball mill in order to reduce power consumption. After the adjustment, the stacking density of the ball stones will increase, and the slurry in the ball mill will be difficult to drain cleanly. In addition, the slurry discharge baskets used in the ball mills are mostly circular hole structures. When discharging slurry, the circular holes will slowly be blocked by the ball stones, and the slurry cannot be discharged normally, resulting in a longer discharge time and low discharge efficiency, which ultimately reduces production efficiency; poor discharge will also cause too much residual slurry in the cylinder of the ball mill, affecting the stability and feed amount of the next feeding formula. In addition, since different products use slurries with different formulas, different slurries require different ball stone ratios in the ball mill, which ultimately results in the same slurry discharge basket being unsuitable for a variety of products. Utility Model Content

[0003] In order to solve or partially solve the problems in the above-mentioned background technology, the utility model provides a novel slurry discharge basket and a ball mill, which can reduce the residual slurry in the ball mill and adapt to the slurry discharge of different ball-stone ratios of the ball mill.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in 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 belong to the protection scope of the utility model.

[0026] The following is combined with Figure 1 To Attachment Figure 5 And specific embodiments describe the present invention in detail.

[0027] like Figure 1-5As shown, the pulp discharge basket provided by the utility model is used to be installed on a ball mill to discharge the slurry in the ball mill. The pulp discharge basket of the embodiment of the present application includes a pulp discharge pipe 1, a mounting plate 2 and a basket body 3 connected in sequence. The pulp discharge pipe 1 is located outside the ball mill 4 and is used to discharge the slurry in the ball mill 4. The mounting plate 2 is used to fix the pulp discharge basket on the ball mill 4, and the basket body 3 extends into the interior of the ball mill 4, so that the slurry in the ball mill 4 enters the basket body 3 and is then discharged through the pulp discharge pipe 1; a through hole is provided in the center of the mounting plate 2, and the basket body 3 is a cylindrical structure with an opening at the upper end, and the pulp discharge pipe 1 and the basket body 3 are connected through the through hole; the cross section of the basket body 3 can be circular, square or polygonal, but is not limited thereto, and can form a cylindrical structure. In the embodiment of the present application, the cross section of the basket body 3 is circular as an example for explanation. A plurality of strip-shaped through holes 31 are provided on the wall surface (bottom wall and side wall) of the basket body 3. The width of the strip-shaped through holes 31 is greater than the diameter of the object to be filtered. Specifically, in the present embodiment, the object to be filtered is a ball. The strip-shaped through hole 31 is a through hole having a length and a width, and its length is greater than its width, and its width is greater than the diameter of the ball, so that the ball cannot pass through the strip-shaped through hole 31, thereby preventing the ball from being discharged from the cylinder of the ball mill 4 along with the slurry. At the same time, if a ball is blocked in the strip-shaped through hole 31, it will not affect the discharge of the slurry by the strip-shaped through hole 31.

[0028] In one embodiment, Figure 1 , Figure 2 As shown, the strip through holes 31 on the side wall of the flower basket body 3 are through holes extending in the vertical direction, that is, the length direction of the strip through holes 31 is the same as the height direction of the flower basket body 3, and a plurality of rows of strip through holes are arranged from top to bottom, and two adjacent strip through holes 31 in each row are staggered so that the strip through holes 31 are arranged on the side wall of the flower basket body 3 as evenly as possible, so that the slurry can enter the flower basket body 3 more evenly and the slurry release time is shortened.

[0029] Specifically, in an optional embodiment, as Figure 1 As shown, the slurry outlet pipe 1 includes a first connecting pipe 11, an elbow 13 and a second connecting pipe 12 which are sequentially connected to the mounting plate 2, and the diameter of the first connecting pipe 11 is greater than the diameter of the second connecting pipe 12. Specifically in this embodiment, the first connecting pipe 11 is a 5-inch pipe, the second connecting pipe 12 is a 4-inch pipe, and the elbow 13 is a 4-inch to 5-inch elbow. The slurry outlet pipe 1 and the mounting plate 2 are both welded together by a welding process using 45# steel, wherein the first connecting pipe 11 is matched with the flower basket body 3. Since the diameter of the flower basket body 3 is relatively large, generally about 300 mm, the first connecting pipe 11 uses a large-diameter pipe to better collect the slurry, and the second connecting pipe 12 is connected to the slurry discharge hose, and the diameter of the hose is generally small. Designing it to be smaller can save materials on the one hand, and facilitate the transfer of the hose on the other hand.

[0030] Specifically, the end of the second connecting pipe 12 is installed with a first fire hose buckle 14 and a butterfly valve 15; it also includes a second fire hose buckle 16 that matches the first fire hose buckle 14, and the second fire hose buckle 16 is fixed on the hose 17. The first fire hose buckle 14 and the second fire hose buckle 16 are used in pairs. Since the traditional slurry release basket directly connects the slurry release basket and the hose with iron wire, the iron wire needs to be removed after use, resulting in material waste and cost increase. The embodiment of the present application uses the first fire hose buckle 14 and the second fire hose buckle 16 to connect the second connecting pipe 12 and the hose 17, which reduces the use of iron wire and reduces the labor intensity of the operator.

[0031] Specifically, in an optional embodiment, the first connecting pipe 11 is a vertical pipe, and a tap water interface 111 and an air interface 112 are provided on its side wall. A first ball valve 113 is installed at the tap water interface 111, and a second ball valve 114 is installed at the air interface 112. The tap water interface 111 is connected to tap water through a tap water pipe, and the air interface 112 is connected to compressed air through an air pipe, and the compressed air adopts 0.7-1.2Mpa. After the slurry in the cylinder of the ball mill 4 is discharged, the butterfly valve 15 on the second connecting pipe 12 is closed, and the tap water interface 111 and the air interface 112 are connected to the tap water pipe and the air pipe respectively, and the first ball valve 113 and the second ball valve 114 are opened, and the flower basket body 3 is rinsed with water and compressed air to facilitate the next use. After flushing, close the first ball valve 113 and the second ball valve 114, rotate the ball mill 4, rotate the end with the pulp basket to the top of the ball mill 4, remove the pulp basket, and after removing the pulp basket, close the cylinder of the ball mill 4, and keep the cleaned water inside the ball mill 4, which can be used next time, reducing the water consumption of external flushing.

[0032] Specifically, in one embodiment, the flower basket body 3 is detachably connected to the mounting plate 2. The flower basket body 3 mainly serves to separate the mud slurry and the balls. Different ball sizes have different requirements on the size of the strip through holes on the flower basket body 3. Therefore, the flower basket body 3 needs to be adaptively replaced according to the size of the balls. The design principle of the width of the strip through holes 31 in the present application is 3 / 4 of the minimum ball diameter. For example, if the minimum ball diameter is 20 mm, the width of the strip through holes 31 is 15 mm. If the minimum ball diameter is 16 mm, the width of the strip through holes 31 is 12 mm. Different flower basket bodies 3 correspond to production slurry conditions with different ball-stone ratios. In actual production, a variety of flower basket bodies 3 of different specifications can be designed according to the size of the balls, which is convenient for replacement and use under different working conditions.

[0033] A sealing ring is provided between the flower basket body 3 and the mounting plate 2 to prevent the slurry from overflowing from the gap between the two. Optionally, a connecting ring 32 is fixed to the upper end of the flower basket body 3, the outer diameter of the connecting ring 32 is 350 mm, and the inner diameter is 300 mm. The sealing ring is arranged between the connecting ring 32 and the mounting plate 2. The sealing ring can be a nitrile rubber pad. A plurality of first connecting holes are provided circumferentially on the connecting ring 32, and the mounting plate 2 is provided with a second connecting hole corresponding to the first connecting hole. The fixing member is inserted into the first connecting hole and the second connecting hole to fix the connecting ring 32 and the mounting plate 2, and at the same time, the sealing ring is squeezed between the two to achieve a sealing effect. The connecting ring 32 and the flower basket body 3 are integrally formed, which is convenient for connecting it with the mounting plate 2. Optionally, the fixing member is a bolt or a screw.

[0034] Specifically, in one embodiment, Figure 3 , Figure 4 As shown, at least two semi-threaded holes 21 are provided on the outer edge of the mounting plate 2, and fasteners 22 are threadedly connected in the semi-threaded holes 21. The fasteners 22 include a fixed portion 221, a threaded portion 222, and an operating portion 223 connected in sequence. The threaded portion 222 is threadedly connected in the semi-threaded holes 21, and the operating portion 223 is located on the side of the mounting plate 2 away from the basket body 3. When the slurry-releasing basket of the present application is mounted on the ball mill 4, the ball cover on the ball mouth 42 of the ball mill 4 is first opened, the slurry or other debris in the ball mouth 42 is cleaned, and the slurry-releasing basket is placed at the ball mouth position, so that the fixed portion 221 of the fastener 22 is stuck in the ball mouth 42 position of the main ball mill, and the threaded portion 222 is stuck in the semi-threaded hole 21. By rotating the operating portion 223, the mounting plate 2 can be raised or lowered, and the slurry-releasing basket can be fastened to the ball mill 4 to avoid spilling slurry. The present application does not limit the manner in which the fixing portion 221 is fixed to the ball mill 4. Optionally, the fixing portion 221 is a circular ring, which is sleeved on the connecting piece of the ball mill 4; or the fixing portion 222 is spherical, which is clamped on the ball mill 4. The structural arrangement of the fastener 22 enables it to be fixed on the ball mill 4 when not in use, so that it is convenient to take at any time and is not easy to lose.

[0035] like Figure 5 As shown, the utility model also provides a ball mill, including a ball body 41, a ball mouth 42 is provided on the ball body 41, and any one of the above-mentioned pulping baskets is installed at the ball mouth 42. The ball mill provided in this application adopts all the technical solutions of all the embodiments of the above-mentioned pulping baskets, and therefore has at least all the beneficial effects brought by the technical solutions of the embodiments of the above-mentioned pulping baskets, which will not be repeated here one by one.

[0036] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
