[0031] like Figure 1 As shown, the present application provides a crushing system, and an embodiment of the crushing system of the present application includes: a liquid storage structure 10, a crusher 20, a first mixing tank 30, a first homogenizing emulsification pump 40, and a discharge part 50; the liquid storage structure 10 is used to store liquid materials; the crusher 20 has a feed inlet, and the liquid storage structure 10 is connected to the crusher 20 to input liquid materials into the crusher 20, and the crusher 20 is used to crush solid materials and form a first mixed material with the liquid material; the first mixing tank 30 is connected to the crusher 20 to input the first mixed material into the first In a mixing tank 30, the liquid storage structure 10 is connected to the first mixing tank 30 to input liquid material into the first mixing tank 30. The first mixing element 31 is provided in the first mixing tank 30. The first mixing element 31 can mix the first mixed material and the liquid material to form a second mixed material; the first homogenizing emulsifying pump 40 is connected to the first mixing tank 30, and the first homogenizing emulsifying pump 40 can crush the solid material in the second mixed material; the discharging part 50 is connected to the first homogenizing emulsifying pump 40, and the discharging part 50 can discharge the solid material and the liquid material.

[0032] The technical solution of this embodiment is applied, the liquid storage structure 10 is used to store liquid materials; the crusher 20 has a feed port, and the solid material enters the crusher 20 through the feed port. The liquid storage structure 10 is connected to the crusher 20 to input the liquid material into the crusher 20, and the solid material and the liquid material form a first mixed material. The crusher 20 can crush the first mixed material to achieve the effect of crushing the solid material; the first mixing tank 30 is connected to the crusher 20 to input the first mixed material into the first mixing tank 30, and the first mixed material enters the crusher 20 after preliminary crushing. To the first mixing tank 30, the liquid storage structure 10 also inputs the liquid material into the first mixing tank 30, and the first mixing element 31 can fully mix the liquid material and the first mixed material and form a second mixed material in the first mixing tank 30; the first homogenizing emulsifying pump 40 is connected to the first mixing tank 30, and the second mixed material enters the first homogenizing emulsifying pump 40, and the first homogenizing emulsifying pump 40 crushes the solid material in the second mixed material again, thereby achieving the effect of secondary crushing of the solid material, and then making the particle size of the crushed solid material smaller, so as to achieve better crushing effect. Therefore, the technical solution of this embodiment can effectively solve the problem of poor crushing effect in the related art.

[0033] It should be noted that the present embodiment is used to crush lithium carbonate so that the particle size of the crushed lithium carbonate can meet the requirements of subsequent carbonization. The first mixed material is a solid-liquid mixture of lithium carbonate and water. Since the water content is relatively small, the first mixed material is in a solid form containing liquid, so that the crusher 20 can crush it more easily. Due to the working requirements of the first homogenizing emulsifying pump 40, more water needs to be added to the first mixed material, so that the second mixed material is in a state of suspension, which is conducive to the first homogenizing emulsifying pump 40 to further crush the solid lithium carbonate particles in the suspension.

[0034] like Figure 1 As shown, the crushing system further includes a second mixing tank 60, which is disposed between the first homogenizing and emulsifying pump 40 and the discharging portion 50, the liquid storage structure 10 is connected to the second mixing tank 60, and a second mixing element 61 is disposed in the second mixing tank 60 to mix the second mixed material and the liquid material to form a third mixed material. Specifically, the second mixing tank 60 and the second mixing element 61 are disposed so that the second mixed material crushed by the first homogenizing and emulsifying pump 40 is fully mixed, thereby forming a more uniformly mixed third mixed material.

[0035] like Figure 1As shown, the crushing system further includes a second homogenizing and emulsifying pump 70, which is disposed between the second mixing tank 60 and the discharging portion 50. The second homogenizing and emulsifying pump 70 can crush the solid materials in the third mixed material. Specifically, the second homogenizing and emulsifying pump 70 can crush the solid materials in the third mixed material again, thereby making the particle size of the lithium carbonate smaller.

[0036] like Figure 1 As shown, the crushing system further includes a material taking valve 90 disposed at the outlet of the second homogenizing and emulsifying pump 70. Specifically, the material taking valve 90 allows the staff to take out the third mixed material, so that the staff can inspect the taken out material and then determine whether the third mixed material meets the requirements.

[0037] like Figure 1 As shown, the crushing system further includes a return part 80, one end of which is connected to the second mixing tank 60, and the other end of which is connected to the outlet of the second homogenizing emulsifying pump 70. Specifically, the return part 80 is a return pipe. If the particle size of lithium carbonate in the third mixed material taken out from the material taking valve 90 is still too large, the staff can return the third mixed material to the second mixing tank 60 through the return part 80, mix it again in the second mixing tank 60, and then crush it again in the second homogenizing emulsifying pump 70, so that the lithium carbonate continues to be crushed, and the cycle is repeated until the particle size of the lithium carbonate meets the requirements.

[0038] In addition, the crushing system further includes a flow control member disposed between the liquid storage structure 10 and the crusher 20 to control the flow of the liquid material. Specifically, the flow control member is used to control the flow of the liquid material input into the crusher 20, so that the staff can better control the relative proportion of the solid material and the liquid material in the first mixed material.

[0039] In addition, in the present embodiment, the crushing system further includes a first liquid level gauge disposed in the first mixing tank 30 and a second liquid level gauge disposed in the second mixing tank 60. Specifically, the first liquid level gauge and the second liquid level gauge are used to monitor the liquid level heights in the first mixing tank 30 and the second mixing tank 60, so that the staff can control the volume of the materials in the first mixing tank 30 and the second mixing tank 60, so as to avoid the materials from overflowing from the first mixing tank 30 and the second mixing tank 60.

[0040] In addition, the maximum power of the first homogenizing and emulsifying pump 40 is greater than the maximum power of the second homogenizing and emulsifying pump 70. Specifically, since the first homogenizing and emulsifying pump 40 only crushes the second mixed material once, the maximum power of the first homogenizing and emulsifying pump 40 is greater than that of the second homogenizing and emulsifying pump 70, thereby ensuring the crushing effect of the second mixed material; since the second homogenizing and emulsifying pump 70 can crush the third mixed material repeatedly, the maximum power of the second homogenizing and emulsifying pump 70 is relatively small, so that the staff can accurately control the third mixed material to be crushed enough times until the particle size of the lithium carbonate in the third mixed material meets the requirements, so that the lithium carbonate does not need to be crushed excessively, thereby saving a certain amount of energy.

[0041] like Figure 1 As shown, the crusher 20 is connected to the first mixing tank 30 through a first pipe 101, and the first pipe 101 is made of stainless steel; the liquid storage structure 10 is connected to the crusher 20 and the first mixing tank 30 through a second pipe 102, and the second pipe 102 is made of plastic. Specifically, the first pipe 101 made of stainless steel has good structural strength and corrosion resistance, which is more conducive to the transportation of the first mixed material, and the second pipe 102 made of plastic has the advantages of being lighter, more durable, and lower in cost; further, the second pipe 102 is made of CPVC (i.e., chlorinated polyvinyl chloride), so that the second pipe 102 has the advantages of high temperature resistance, chemical corrosion resistance, stronger, higher rigidity, and better flame retardancy.

[0042] like Figure 1 As shown, the first mixer 31 includes a first rotating shaft 311 and a first blade 312 disposed on the first rotating shaft 311; the second mixer 61 includes a second rotating shaft 611 and a second blade 612 and a third blade 613 disposed on the second rotating shaft 611, and the second blade 612 and the third blade 613 are disposed at intervals in the axial direction of the second rotating shaft 611. Specifically, the arrangement of the first rotating shaft 311 and the first blade 312 enables the first mixer 31 to have the advantages of easy processing and good mixing effect; the second blade 612 is located above the third blade 613, and the arrangement of the second blade 612 and the third blade 613 enables the second mixer 61 to have more blades, so that the second mixer 61 has a better mixing effect on the third mixed material.

[0043] Specifically, the crushing system of this embodiment is used, and the following steps are adopted:

[0044] Step 1: Turn on the crusher 20, and continuously add lithium carbonate into the crusher through the feed port, and allow the liquid storage structure to continuously add water into the crusher at a rate of 2 tons / hour;

[0045] Step 2: before the first mixed material enters the first mixing tank 30, add 50% of the volume of water into the first mixing tank 30 and start the first mixing element 31;

[0046] Step 3: Allow the first mixed material to enter the first mixing tank 30 and continuously inject water at a rate of 2 tons / hour;

[0047] Step 4: Start the mechanical seal cooling water of the first homogenizing and emulsifying pump 40, gradually increase the frequency and allow the second mixed material to enter the first homogenizing and emulsifying pump 40, and keep the liquid level of the first mixing tank 30 at 50% of its volume;

[0048] Step 5: Before the second mixed material enters the second mixing tank 60, add 20%-30% of water in the second mixing tank 60 and start the second mixing element 61;

[0049] Step 6: Continue to add water to the second mixing tank 60 until the volume reaches 30%-40%, and then start the second homogenizing and emulsifying pump 70 to seal the cooling water;

[0050] Step 7: Allow the second mixed material to enter the second mixing tank 60 to form a third mixed material, and then allow the third mixed material to enter the second homogenizing emulsification pump 70;

[0051] Step 8: Take material from the material taking valve 90. If the particle size of the lithium carbonate does not meet the requirements, the third mixed material is repeatedly mixed and crushed between the second mixing tank 60 and the second homogenizing emulsification pump 70 through the return part 80 until the particle size of the lithium carbonate meets the requirements, and then discharged through the discharging part 50.

Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0053] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0054] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
