[0016] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] Reference Figures 1 to 8 The present invention provides an automatic grinding device for raw materials for preparing calcium carbonate, which comprises a grinding cylinder 1, a storage mechanism 2 and a replacement mechanism 3. The grinding cylinder 1 is used to accommodate the raw materials for preparing calcium carbonate. The grinding cylinder 1 can be rotatably arranged on a frame, the grinding cylinder 1 is arranged horizontally, the storage mechanism 2 is arranged outside the grinding cylinder 1, and a plurality of groups of grinding balls are stored in the storage mechanism 2. The size of each group of grinding balls is different. The replacement mechanism 3 is arranged between the storage mechanism 2 and the grinding cylinder 1. The replacement mechanism 3 is used to take out the large-sized grinding balls in the grinding cylinder 1 and put them into the storage mechanism 2, and at the same time, to take out the small-sized grinding balls in the storage mechanism 2 and put them into the grinding cylinder 1, so as to replace the grinding balls, so that the size of the grinding balls in the grinding cylinder 1 gradually becomes smaller, thereby improving the grinding efficiency.

[0018] The automatic grinding device for preparing calcium carbonate raw materials in this embodiment is provided with a storage mechanism 2 and a replacement mechanism 3. During the grinding process of the calcium carbonate raw materials, the prepared raw materials are firstly ground with large-sized grinding balls, and then the grinding balls are replaced by the replacement mechanism 3, and the large-sized grinding balls are replaced by medium-sized grinding balls. The prepared raw materials after the initial grinding are subjected to secondary grinding. Then, the grinding balls are replaced by the replacement mechanism 3, and the medium-sized grinding balls are replaced by small-sized grinding balls. The prepared raw materials after the secondary grinding are finely ground, so that the prepared raw materials are crushed and ground by the larger-sized grinding balls when they are larger in size, and are crushed and ground by the smaller-sized grinding balls when they are smaller in size. That is, the prepared raw materials are subjected to targeted grinding treatment, thereby improving the grinding effect.

[0019] Specifically, refer to Figures 4 to 8The storage mechanism 2 includes a storage bracket 201, which is connected with a storage top plate 202, a storage box body 203 and a storage bottom plate 204 from top to bottom in sequence. The storage top plate 202 is horizontally arranged and a first sliding groove 205 is arranged through the middle thereof. A first sliding seat 206 is slidingly arranged in the first sliding groove 205, and a first storage bucket 207 is connected to the first sliding seat 206. The lower end of the first storage bucket 207 vertically passes through the first sliding seat 206, and the lower end of the first storage bucket 207 is fixedly connected to the first sliding seat 206. A linear motor is arranged in the first sliding groove 205, and the output end of the linear motor is connected to the first sliding seat 206. During operation, the linear motor drives the first sliding seat 206 to slide in the first sliding groove 205, thereby driving the first storage bucket 207 to move, so that the position of the lower end outlet of the first storage bucket 207 changes.

[0020] Furthermore, the first storage bucket 207 is located above the storage box body 203, the upper end of the storage box body 203 is open, and the storage box body 203 includes a plurality of storage chambers 208 arranged vertically side by side. When the first sliding seat 206 moves, the first storage bucket 207 passes through the plurality of storage chambers 208 in sequence.

[0021] Further, refer to Figure 8 A second storage bucket 209 is provided above the storage bottom plate 204 , and the second storage bucket 209 is located below the storage cavity 208 . A discharge pipe 210 is connected to the lower end of the second storage bucket 209 . The discharge pipe 210 vertically passes through the storage bottom plate 204 , and the storage bottom plate 204 is fixedly connected to the discharge pipe 210 .

[0022] Reference Figure 1 and Figure 3 The replacement mechanism 3 in this embodiment includes a collecting plate 301 and a releasing pipe 302. The two ends of the grinding cylinder 1 are respectively set as a material inlet and outlet 101 and a ball inlet and outlet 102. The material inlet and outlet 101 is used for the entry and exit of prepared raw materials and ground powders, and the ball inlet and outlet 102 is used for the entry and exit of grinding balls. A replacement door 103 is provided on the ball inlet and outlet 102. The collecting plate 301 and the releasing pipe 302 are directly opposite to the replacement door 103.

[0023] Among them, the collecting plate 301 and the releasing pipe 302 are both connected to the receiving bracket 201, and the collecting plate 301 is located above the releasing pipe 302. The collecting plate 301 is arranged along the axial direction of the grinding cylinder 1. A collecting chute 303 is arranged on the collecting plate 301. The end of the collecting chute 303 is located above the first receiving bucket 207. The releasing pipe 302 is connected to the unloading pipe 210.

[0024] Furthermore, the replacement mechanism 3 further includes a translation sliding base 304, which is arranged at one side of the grinding cylinder 1, and is provided with a translation sliding groove 305 on the translation sliding base 304, in which a translation sliding seat 306 is slidably arranged, and the storage bracket 201 is mounted on the translation sliding seat 306, and a linear motor is arranged in the translation sliding groove 305, and the output end of the linear motor is connected to the translation sliding seat 306. When it is working, the linear motor drives the translation sliding seat 306 to slide in the translation sliding groove 305, thereby driving the storage bracket 201 to move, that is, driving the storage mechanism 2 to move.

[0025] It should be noted that, in this embodiment, the replacement mechanism 3 works in the intermittent period of the action of the grinding cylinder 1. After the calcium carbonate preparation raw material is poured into the grinding cylinder 1, the replacement mechanism 3 drives the storage mechanism 2 to move into the grinding cylinder 1. When the grinding cylinder 1 rotates, the grinding balls move upward along the grinding cylinder 1, and fall freely after moving to the top. At this time, the collecting plate 301 in the storage mechanism 2 moves into the grinding cylinder 1 and is on the falling trajectory of the grinding balls. The collecting chute 303 has a certain inclination angle. After the grinding balls fall into the collecting chute 303, the grinding balls will roll along the collecting chute 303 and finally fall into the first receiving bucket 207, thereby being collected by the storage box body 203.

[0026] After the grinding balls are collected into the storage box 203, the storage box 203 releases the smaller grinding balls, which fall into the second storage bucket 209 and into the release pipe 302 through the discharge pipe 210. The release pipe 302 follows the collecting plate 301 into the grinding cylinder 1, so the grinding balls fall into the grinding cylinder 1, thereby realizing the replacement of the grinding balls.

[0027] It should be further explained that, referring to Figure 6 and Figure 7 There are three storage chambers 208, which are respectively a first storage chamber 2081, a second storage chamber 2082 and a third storage chamber 2083. The bottoms of the first storage chamber 2081, the second storage chamber 2082 and the third storage chamber 2083 are respectively provided with a first closing component, a second closing component and a third closing component. The first closing component is used to control the opening and closing of the lower end outlet of the first storage chamber 2081, the second closing component is used to control the opening and closing of the lower end outlet of the second storage chamber 2082, and the second closing component is used to control the opening and closing of the lower end outlet of the third storage chamber 2083.

[0028] Among them, the first sealing component, the second sealing component and the third sealing component act in linkage. After the first sealing component closes the lower end outlet of the first storage chamber 2081 for a predetermined time, the second sealing component opens the lower end outlet of the second storage chamber 2082 to allow the grinding balls in the second storage chamber 2082 to flow out. After the second sealing component closes the lower end outlet of the second storage chamber 2082 for a predetermined time, the third sealing component opens the lower end outlet of the third storage chamber 2083 to allow the grinding balls in the third storage chamber 2083 to flow out.

[0029] During the operation of the whole calcium carbonate raw material automatic grinding device, the calcium carbonate raw material is first poured into the grinding cylinder 1, the replacement mechanism 3 drives the storage mechanism 2 to move into the grinding cylinder 1, the first sealing component controls the lower end outlet of the first storage chamber 2081 to open, so that the large-sized grinding balls fall into the grinding cylinder 1, and then the replacement mechanism 3 drives the storage mechanism 2 to reset, the grinding cylinder 1 drives the raw material and the large-sized grinding balls to rotate, and the large-sized grinding balls crush the raw material; After a period of time, the first sealing component closes the lower outlet of the first storage chamber 2081. After the lower outlet of the first storage chamber 2081 is closed for a predetermined time, the replacement mechanism 3 drives the storage mechanism 2 to move into the grinding cylinder 1, and the large-sized grinding balls are collected by the replacement mechanism 3 into the storage mechanism 2. At the same time, the second sealing component opens the lower outlet of the second storage chamber 2082, and the medium-sized grinding balls stored in the second storage chamber 2082 are then driven by the replacement mechanism 3 to reset the storage mechanism 2, and the grinding cylinder 1 drives the raw materials and the medium-sized grinding balls to rotate, and the medium-sized grinding balls crush and grind the raw materials; After a period of time, the second sealing component closes the lower outlet of the second storage chamber 2082. After the lower outlet of the second storage chamber 2082 is closed for a predetermined time, the replacement mechanism 3 drives the storage mechanism 2 to move into the grinding cylinder 1, and the medium-sized grinding balls are collected by the replacement mechanism 3 into the storage mechanism 2. At the same time, the third sealing component opens the lower outlet of the third storage chamber 2083, and the small-sized grinding balls stored in the third storage chamber 2083 are received. Then, the replacement mechanism 3 drives the storage mechanism 2 to reset, and the grinding cylinder 1 drives the raw materials and the small-sized grinding balls to rotate, and the small-sized grinding balls crush and grind the raw materials. After a period of time, the third closing component closes the lower outlet of the third storage chamber 2083.
