Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a high-efficiency crushing device. Background Art

[0002] A pulverizer is a machine that crushes large solid materials into the required size. Depending on the size of the material being crushed or pulverized, pulverizers can be categorized as coarse crushers, pulverizers, and ultrafine pulverizers. The external forces applied to the solid during the pulverization process include shearing, impact, crushing, and grinding. Shearing is primarily used for coarse crushing and pulverization, and is suitable for crushing or pulverizing tough or fibrous materials and large bulk materials.

[0003] For example, the authorization announcement number "CN205700914U" is named as a high-efficiency crushing device. By arranging an extrusion chamber and a crushing chamber in the second crushing barrel, the material after preliminary crushing can be squeezed and then crushed, so that the material is crushed more thoroughly, and the working efficiency of the crushing device is improved. However, the existing high-efficiency crushing device pours large pieces of material into the crushing device, and the material is ground and crushed by the spiral blade and the crushing barrel before being discharged downward. However, this method of crushing first and then grinding and crushing is more suitable for crushing materials with high hardness and easy to powder. However, when facing materials with certain viscosity or strong toughness, the method of crushing first and then grinding and crushing will cause the squeezed material to clump together, so it is not easy to fall into the subsequent crushing barrel for crushing, which greatly affects the crushing efficiency of the high-efficiency crushing device.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

The crushing box 1 is movably connected to both sides of the extrusion box 2. An observation window 5 is fixedly opened on the outer wall of the extrusion box 2. The observation window 5 is made of transparent tempered glass. The observation window 5 is convenient for helping staff to observe the crushing of the material inside. The interior of the crushing box 1 is provided with a grinding and crushing structure 3, the inside of the extrusion box 2 is provided with an extrusion crushing structure 4, the outside of the crushing box 1 is provided with a splicing and rotating connection structure 6, and high-efficiency crushing feeding structures 7 are provided at both ends of the crushing box 1.

When selecting the motor 31, a model that can meet the usage requirements can be selected. The output shafts of the two motors 31 are fixedly connected to the two rotating shafts 32. When the crushing box 1 falls above the extrusion box 2, the material is poured into the inner side of the crushing box 1. The power is connected to start the motor 31. The motor 31 will drive the rotating shaft 32 to rotate. The rotating shaft 32 can drive the outer crushing roller 33 to rotate. The two relatively rotating crushing rollers 33 will use the multiple crushing protrusions 34 around them to grind and crush the poured material. Then the crushed material slides down along the discharge cavity 35 into the inside of the extrusion box 2 below. The outer sides of the two rotating shafts 32 are fixedly sleeved with two crushing rollers 33. The outer walls of the two crushing rollers 33 are fixedly connected with multiple crushing protrusions 34. The inner side of the crushing box 1 is fixedly connected with the discharge cavity 35, and the inner side of the discharge cavity 35 is movably connected to the crushing roller 33.

[0024] The extrusion crushing structure 4 includes a hydraulic cylinder 41 and a reinforcement plate 43. The two reinforcement plates 43 are fixedly mounted on the inner wall of the extrusion box 2. The reinforcement plates 43 are made of strong, pressure-resistant, high-strength metal steel material and can withstand the extrusion pressure of the hydraulic cylinder 41. The inner sides of the two reinforcement plates 43 are fixedly connected with a discharge slope 42. The discharge slope 42 can guide the material to the inner side of the two extrusion plates 44. When the material falls into the extrusion box 2, the power is connected to turn on the hydraulic cylinder 41. The hydraulic cylinder 41 pushes the two extrusion plates 44 inward to close for secondary or primary extrusion to increase the crushing efficiency. The two hydraulic cylinders 41 are fixedly mounted on the inner side of the extrusion box 2, and two extrusion plates 44 are fixedly mounted on the ends of the two hydraulic cylinders 41.

[0025] The splicing and reversible connection structure 6 includes a connecting piece 61 and a mounting bolt 62. A plurality of connecting pieces 61 are fixedly mounted on both ends of the outer wall of the crushing box 1. The connecting pieces 61 can be separated. When it is necessary to crush larger pieces of materials that are not easy to agglomerate, the extrusion box 2 is placed on top of the crushing box 1, and then the connecting piece 61 is docked. The mounting bolts 62 are inserted into the inner sides of the plurality of through holes 63 and tightened upward with the nut 64. In this way, the extrusion box 2 first squeezes the large pieces of materials into small pieces, which is convenient for grinding and crushing inside the crushing box 1 below. On the contrary, when it is necessary to crush some sticky materials, When the material is easy to clump, the crushing box 1 is dropped onto the top of the extrusion box 2. After being ground and crushed by the crushing box 1, the powdered material will be squeezed again by the extrusion plate 44 to break up the clumping blocks for easy collection. A plurality of connecting pieces 61 are fixedly mounted on both ends of the outer wall of the extrusion box 2. The plurality of connecting pieces 61 are movably connected to each other. Through holes 63 are fixedly opened on the inner sides of the plurality of connecting pieces 61. The inner sides of the plurality of through holes 63 are movably connected with mounting bolts 62. The other ends of the two mounting bolts 62 are threadedly connected with nuts 64. The top ends of the two nuts 64 are movably connected to the outer walls of the connecting pieces 61.

[0026] The connecting pieces 61 can be separated. When it is necessary to crush larger pieces of material that are not easy to agglomerate, the extrusion box 2 is dropped on the crushing box 1, and then the connecting piece 61 is docked, the mounting bolts 62 are inserted into the inner sides of the multiple through holes 63, and the nuts 64 are rotated upward to tighten. In this way, the extrusion box 2 first squeezes the large pieces of material into small pieces, which is convenient for grinding and crushing inside the crushing box 1 below. Conversely, when it is necessary to crush some viscous materials that are easy to agglomerate, the crushing box 1 is dropped on the top of the extrusion box 2. After being ground and crushed by the crushing box 1, the powdered material will be squeezed again by the extrusion plate 44 to break up the agglomerates for easy collection. The crushing efficiency of the high-efficiency crushing device is improved by using a crushing device that adopts different combinations to deal with materials in different forms.

The motor 31 will drive the rotating shaft 32 to rotate, and the rotating shaft 32 can drive the outer crushing roller 33 to rotate. The two relatively rotating crushing rollers 33 will use the multiple crushing protrusions 34 around them to crush and grind the poured material, and then the crushed material will slide down along the discharge cavity 35 to the inside of the extrusion box 2 below.

When the material falls into the extrusion box 2, the power is connected to start the hydraulic cylinder 41, and the hydraulic cylinder 41 pushes the two extrusion plates 44 inward to close for secondary or primary extrusion, thereby increasing the crushing efficiency.

[0033] The high-efficiency crushing device can be turned over to crush the structure according to the material form;

[0034] They can be separated by the connecting pieces 61. When it is necessary to crush larger pieces of material that are not easy to agglomerate, the extrusion box 2 is dropped on the crushing box 1, and then the connecting piece 61 is docked, the mounting bolts 62 are inserted into the inner sides of the multiple through holes 63, and the nuts 64 are rotated upward to tighten. In this way, the extrusion box 2 first squeezes the large pieces of material into small pieces, which is convenient for grinding and crushing inside the crushing box 1 below. Conversely, when it is necessary to crush some viscous materials that are easy to agglomerate, the crushing box 1 is dropped on the top of the extrusion box 2. After being ground and crushed by the crushing box 1, the powdered material will be squeezed again by the extrusion plate 44 to break up the agglomerates for easy collection.

Similarly, the second feed port 73 is used to pour materials into the extrusion box 2 for extrusion operation. The crushed materials after extrusion are discharged along the second discharge port 74 or fall into the crushing box 1 for crushing. The first feed port 71 is connected to the top of the first discharge port 72, and the bottom of the second feed port 73 is connected to the top of the second discharge port 74. The inner lower ends of the two crushing rollers 33 are arranged opposite to the first discharge port 72, and the lower parts of the two extrusion plates 44 are arranged opposite to the second discharge port 74.
