[0002] In the production process of electrolyte, there are many different types of solid powders in the formula, and these solid materials cannot come into contact with the air, so they need to be contained in pressure barrels. The volume of pressure barrels varies, and the stored materials range from 10kg to 1500kg. Due to differences in the stacking density, repose angle, extrusion strength, etc. of the materials, the materials stored in the pressure barrels will form bridges or agglomerates after a long period of transportation due to continuous squeezing between the material molecules, resulting in accumulation of materials in the barrel when the materials are transported to the use end and unable to be unloaded. At this time, workers are required to repeatedly knock on the barrel wall or roll and other complex methods to dredge the materials. Materials that cannot be dredged need to disassemble the barrel and then dredge manually. The whole process is cumbersome and affects production efficiency. There are also safety and quality issues, and it is easy to introduce foreign matter. Utility Model Content

DETAILED DESCRIPTION

[0032] 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.

[0033] The following is combined with Figure 1 To Attachment Figure 7 And specific embodiments discuss the utility model in detail.

[0034] like Figure 1-7 As shown, the utility model provides an automatic crushing device for solid materials in a pressure barrel, which is used to crush the agglomerated materials in the pressure barrel so that the materials in the pressure barrel can smoothly enter the use end. The crushing device includes a frame 1, a lifting mechanism 2 and a crushing mechanism 3; wherein the lifting mechanism 2 is connected to the top of the frame 1, and a pressure barrel 4 is installed on the lifting mechanism 3, and the pressure barrel 4 can move up and down above the frame 1 under the action of the lifting mechanism 2; the crushing mechanism 3 is arranged on the frame 1, and the crushing mechanism 3 includes a power rod 31 and a first driving component 32 for driving the power rod 31 to rotate, and at least one flexible rope (not shown in the figure) is provided on the outer side wall of the top of the power rod 31, and when the power rod 31 is not rotating, the flexible rope is set to hang down, and when the power rod is driven by the first driving component 32 to rotate at high speed, the free end of the flexible rope gradually unfolds outward until it is horizontal. It can be seen that During the rotation of the power rod 31, the range of the flexible rope crushing gradually increases, and finally the agglomerated materials at various points in the pressure barrel 4 are mechanically crushed; the pressure barrel 4 has a discharge port, and the power rod 31 extends upward into the pressure barrel 4 from the discharge port. During the up and down movement of the pressure barrel 4, the flexible rope is always located in the pressure barrel 4; the lifting mechanism 2 drives the pressure barrel 4 to move up and down, so that the flexible rope rotates at different positions in the pressure barrel 4. In other words, the flexible rope can rotate at high speed in the pressure barrel 4 under the drive of the first driving component 32. During the rotation, the flexible rope gradually stretches out to form a breaking force device with a certain strength, so as to crush the agglomerated materials at different positions in the pressure barrel 4.

[0035] It should be noted that the present application does not limit the specific composition structure of the lifting mechanism 2. All lifting mechanisms that can drive the pressure barrel 4 to move up and down belong to the protection scope of the present application. Optionally, the lifting mechanism 4 is a lifting mechanism in the prior art such as a screw elevator, a belt drive elevator, and a rack and pinion elevator. For example, the frame 1 of the present application has an installation platform 11, and the lifting mechanism 2 is arranged on the installation platform 11. The lifting mechanism 2 includes a screw rod 21 which is circumferentially arranged on the installation platform 11 and extends upward. Each screw rod 21 is provided with a turbine 22, and the turbine 22 is fixed on the lifting platform 23. The turbines 22 are connected by transmission shafts 24, one of which is a driving shaft 25. A lifting motor 26 is fixed on the lifting platform 23, and the output shaft of the lifting motor 26 is connected to a dual-output reducer 27. The driving shaft 25 is connected to the output shaft of the dual-output reducer 27. The lifting motor 26 drives the output shaft of the dual-output reducer 27 to rotate, and the output shaft drives the driving shaft 25 to rotate. The two ends of the driving shaft 25 are respectively connected to the turbines 22, thereby realizing the synchronous rising of multiple turbines 22 along the screw rod 21, and the pressure barrel 4 is connected to the lifting platform 23 through the unloading flange 5 or the pressure barrel 4 is fixed to the lifting platform 23 through the barrel rack, thereby realizing the lifting and lowering of the pressure barrel 4.

The side wall of the mounting portion is provided with at least one mounting hole 3111 that passes through the inside and outside. The mounting hole 3111 is used to fix the flexible rope to the top of the power rod 31. Normally, one flexible rope is provided, but in actual use, two or more flexible ropes may be provided as needed, so as to more thoroughly break up the agglomerated materials in the pressure barrel. The purpose of providing the mounting column 311 in the present application is to provide an installation space for the flexible rope, so as to facilitate the replacement of flexible ropes of different lengths according to different pressure barrel volumes, so as to achieve the versatility of the crushing device. In other embodiments, an installation space for the flexible rope may also be provided at the top of the power rod 31, without specific structural limitations.

[0037] In some embodiments, see Figure 6 , Figure 7The frame 1 provides support for the first drive assembly 32 and the second drive assembly 34. The first drive assembly 32 includes a first motor 321 fixed to the lower part of the frame 1 and a reducer 322 connected to the output end of the first motor 321. The output shaft of the reducer 322 is fixedly connected to the lower end of the power rod 31. The first motor 321 drives the output shaft of the reducer 322 to rotate, thereby driving the power rod 31 to rotate at high speed. Of course, the present application may also select a first drive assembly 32 of other structures, which can achieve high-speed rotation of the power rod 31 and falls within the protection scope of the present application.

[0038] In some embodiments, see Figure 4 The crushing mechanism 3 also includes a tube body 33 sleeved on the outer periphery of the power rod 31, and the inner diameter of the tube body 33 is larger than the outer diameter of the power rod 31, that is, there is a gap and no contact between the tube body 33 and the power rod 31; the top of the power rod 31 passes through the top of the tube body 33 and extends out, and the flexible rope is located above the tube body 33; the lower end of the tube body 33 is connected to a second driving component 34 that drives it to rotate, that is, the power rod 31 and the tube body 33 of the present application move independently of each other, the power rod 31 can rotate independently inside the tube body 33, and the tube body 33 can also rotate independently outside the power rod 31, and the two do not interfere with each other. Optionally, in some embodiments, the second drive assembly 34 includes a second motor 341 fixed to the lower part of the frame 1, a first bevel gear 342 mounted on the output shaft of the second motor 341, and a second bevel gear 343 meshing with the first bevel gear 342, the second bevel gear 343 is fixedly mounted on the outer wall of the tube body 33, and the power is transmitted to the tube body 33 through the meshing of the first bevel gear 342 and the second bevel gear 343. Of course, the present application may also select a second drive assembly 34 of other structures, which can realize the rotation of the tube body 33 and belongs to the protection scope of the present application. More specifically, a motor mounting frame is provided below the frame 1 of the present application, the first motor 321 is mounted on the upper and lower end surfaces of the motor mounting frame, the second motor 341 is mounted on the side of the motor mounting frame, the first motor 321 is arranged vertically, and the second motor 341 is arranged horizontally, so that the device is more compact.

[0039] In some embodiments, see Figure 3The outer wall of the tube body 33 is provided with a spiral groove, in which a rotating blade 35 is fixedly installed. There are multiple rotating blades 35, and a spiral structure is formed on the outer wall of the tube body 33. The rotating blade 35 can assist in crushing a part of the material, and when the tube body 33 moves downward relative to the pressure barrel 4, the spiral rotating blade 35 can be used to bring the material out of the pressure barrel 4 to avoid the crushed material from piling up again. Before using the flexible rope on the power rod 31 to crush the material, the present application can first drive the rotating blade 35 to rotate through the tube body 33, crush part of the agglomerated material located in the center of the pressure barrel 4 and bring it out of the barrel, freeing up space for the rotation of the flexible rope, which is more conducive to crushing the agglomerated material at the edge of the pressure barrel 4.

[0040] It is worth mentioning that the rotating blade 35 of the present application forms a spiral structure on the outer wall of the tube body 33, forming a spiral material discharge guide channel. During the relative downward movement of the tube body, the material is brought out of the pressure barrel 4 through the material discharge guide channel.

[0041] In a specific embodiment, ball bearings are provided between the inner wall at the top of the tube body 33 and the outer wall at the top of the power rod 31, and between the inner wall at the bottom of the tube body 33 and the outer wall at the bottom of the power rod 31. The ball bearings can achieve the stability of the rotation of the tube body 33 and the power rod 31.

[0042] In some embodiments, a discharge port of the pressure barrel 4 is connected to a discharge flange 5, which is connected to the lifting mechanism 2, such as the lifting platform 23 mentioned above, and the discharge flange 5 has a first feed port and a first discharge port; a discharge pipe 6 is fixed to the frame 1, and the discharge pipe 6 is located below the mounting platform 11, and a second feed port and at least one second discharge port 61 are provided on the discharge pipe 6; an elastic shrink pipe 7 is connected between the first discharge port and the second feed port, and the elastic shrink pipe 7 is sleeved on the outer periphery of the tube body 33 or the power rod 31, and can be adaptively expanded and contracted with the lifting and lowering of the discharge flange 5, and a certain blanking space is formed between the elastic shrink pipe 7 and the tube body 33. In the process of the pressure barrel 4 rising and the tube body 33 relatively descending, the rotating blade 35 on the outer wall of the tube body 33 continuously brings the crushed material out into the elastic shrink pipe 7, and finally enters the discharge pipe from the second feed port, and then transports the material to the use end through the second discharge port 61.

[0043] In a preferred embodiment, the elastic contraction pipe 7 is an expansion joint, which can move up and down with the pressure barrel 4. The storage interval of the expansion joint can be flexibly controlled. The expansion joint can also be isolated from the outside world, and it has a high degree of matching with hard equipment.

[0044] In some embodiments, the flexible rope is a high-strength nylon rope that can be stretched out when rotating at high speed to break up the agglomerated materials in the pressure barrel.

[0045] Specifically, the length of the flexible rope is not greater than the inner diameter of the pressure barrel, that is, the flexible rope can freely rotate at high speed in the pressure barrel.

[0046] The working principle of the utility model is as follows: the tube body 33 and the power rod 31 extend into the pressure barrel 4 from the discharge port of the pressure barrel 4, the lifting mechanism 2 is started to move the pressure barrel 4 downward, and the second motor 341 is started to rotate the tube body 33. During the downward movement of the pressure barrel 4, the tube body 33 moves upward relative to the pressure barrel 4. The tube body 33 rotates in the pressure barrel 4 to crush the materials within a certain range (such as a radius of about 5 cm) to leave a rotation space for the flexible rope; then the first motor 321 is started to rotate the power rod 31 at a high speed, and the flexible rope continuously expands the rotation space, continuously crushes the agglomerated materials at other positions in the pressure barrel 4 (such as the range outside the 5 cm radius), and brings the materials out to the elastic shrink pipe 7 through the rotating blade 35 on the outer wall of the tube body 33, and finally enters the use end from the second discharge port 61.

[0047] 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.
