Description

Technical Field

[0001] The invention relates to the technical field of squirrel cage crushers, in particular to an anti-sticking squirrel cage crusher. Background Art

[0002] The squirrel cage crusher uses a high-speed rotating hammer to impact the suspended material to crush the raw material. It has the advantages of small crushing particle size and large crushing ratio. It is widely used in mining, building materials, chemicals, feed, food, medicine, plastics and other industries, and is mainly suitable for crushing some low-hardness materials. At present, squirrel cage crushers are used in the production of fracturing proppants in the petrochemical industry. They are the main production equipment and play an important role in the effective operation of the production line.

[0003] However, since the crushed materials have a certain amount of moisture and contain adhesives, the existing squirrel cage crusher has serious material sticking inside the casing during use, which causes friction and extrusion between the outside of the large rotor beater and the sticky materials. The more friction and extrusion, the harder the sticky materials become, which in turn causes the following problems. First, the beater is worn or broken, greatly reducing its service life; second, it increases the running resistance of the equipment and energy consumption, and in more serious cases, it can cause the motor to burn out, the rotor bearing to twist and break, etc.; third, it can cause the material to not be effectively crushed, and material to accumulate inside the rotor, etc. The machine is often forced to shut down for cleaning and maintenance, which is time-consuming and labor-intensive, and seriously affects production.

DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] The present invention provides Figure 1-6 The squirrel cage crusher for preventing sticking materials shown in the figure comprises a full-length base 23, with boxes 1 fixedly arranged on both sides of the top of the base 23, a casing 2 arranged on the top of the base 23, and the casing 2 is located between the two boxes 1. The casing 2 is made of wear-resistant steel plate, which improves the wear resistance of the present invention when crushing materials and prolongs the service life of the present invention;

[0044] Moreover, if Figure 1-4 As shown, in the present invention, the cross section of the upper half of the casing 2 is set to be rectangular, and the cross section of the lower half of the casing 2 is set to be semicircular, so that the top of the casing 2 can be lifted up by 150mm-200mm, and the side is expanded outward by 50mm-200mm, thereby expanding the space inside the casing 2, increasing the distance from the material to the inner wall of the casing, reducing the power, and not easy to stick;

[0045] In order to crush the materials falling into the housing 2, Figure 4-11As shown, a rotatable first rotor 3 is provided on the left side of the casing 2, and a plurality of first hitting sticks 4 and a plurality of second hitting sticks 6 are distributed in a circular array on the right side of the first rotor 3 with the center of the first rotor 3 as the center. The first hitting stick 4 is arranged on the outer circle of the second hitting stick 6, and the right ends of the plurality of first hitting sticks 4 are equipped with the same first fixing ring 5, and the right ends of the plurality of second hitting sticks 6 are equipped with the same second fixing ring 7. A rotatable second rotor 12 is provided on the right side of the casing 2, and a plurality of third hitting sticks 13 and a plurality of fourth hitting sticks 15 are distributed in a circular array on the left side of the second rotor 12 with the center of the second rotor 12 as the center. The third hitting stick 13 is arranged on the outer circle of the second hitting stick 6. On the outer circle of the fourth stick 15; the left ends of the plurality of third sticks 13 are equipped with the same third ring 14, and the left ends of the plurality of fourth sticks 15 are equipped with the same fourth ring 16; the plurality of third sticks 13 are nested between the first stick 4 and the second stick 6, and the plurality of second sticks 6 are nested between the third stick 13 and the fourth stick 15, the first fixing ring 5 covers the outer ends of the third sticks 13, the third ring 14 covers the outer ends of the second sticks 6, and the second fixing ring 7 covers the outer ends of the fourth stick 15, the first rotor 3 and the second rotor 12 rotate in opposite directions and the rotation speed of the first rotor 3 is greater than the rotation speed of the second rotor 12;

[0046] The material is crushed when it falls into the casing 2. During this process, the first striking stick 4 and the second striking stick 6 on the first rotor 3 and the third striking stick 13 and the fourth striking stick 15 on the second rotor 12 start to rotate in different directions. The material to be crushed enters between the plurality of fourth striking sticks 15, and then collides with the first striking stick 4, the second striking stick 6, the third striking stick 13 and the fourth striking stick 15 rotating at high speeds when falling. The bulk material is broken up and crushed. The materials collide with each other and other bulk materials collide with the inner wall of the casing 2 and are also crushed. The crushed material then falls down, thereby completing the crushing process.

[0047] During the crushing process, since the length of the first striking stick 4 is greater than that of the second striking stick 6, and the lengths of the third striking stick 13 and the fourth striking stick 15 are equal and less than that of the second striking stick 6, different intensities of striking force can be applied to improve the crushing effect. Moreover, the interior of the casing 2 is expanded and the top is designed to be rectangular. Compared with the squirrel cage crusher in the prior art, the top of the casing 2 can be lifted up by 150mm-200mm, and the side is expanded outward by 50mm-200mm, thereby increasing the space between the first striking stick 4 and the inner wall of the casing 2, thereby increasing the distance from the material to the casing 2, reducing the power when reaching the casing 2, and not being easy to stick. At the same time, it has a certain amount of time to fall, so it will not be squeezed by the first striking stick 4 quickly and accumulated layer by layer, thereby extending the maintenance and cleaning interval time, extending the service life of the first striking stick 4, reducing equipment failures, saving energy and reducing consumption, and ensuring normal production.

[0048] Furthermore, in order to drive the first rotor 3 and the second rotor 12 to rotate, Figure 1-9As shown, the first rotor 3 is connected to the first shaft 9 through the first flange 10 on the right side, the left end of the first shaft 9 penetrates the casing 2 and extends out of the left side of the casing 2, the first shaft 9 is movably connected to the casing 2 through a bearing, and the left end of the first shaft 9 is provided with a first driving assembly to drive the first shaft 9 to rotate; a plurality of first mounting holes 8 are provided on the first rotor 3, the first flange 10 is provided on the left side of the first rotor 3, a plurality of first bolts 11 are threadedly connected to the first flange 10, one end of the first bolt 11 penetrates the first mounting hole 8 and is threadedly connected to the first mounting hole 8; the fourth ring 16 is connected to the second shaft 17 through the second flange 18 on the right side, the right end of the second shaft 17 penetrates the casing 2 and extends out of the right side of the housing 2, the second rotating shaft 17 is movably connected to the housing 2 through a bearing, and in order to support the first rotating shaft 9 and the second rotating shaft 17, the left end of the first rotating shaft 9 and the right end of the second rotating shaft 17 respectively pass through two bearing seats in sequence, the bearing seats are located on the top of the chassis 1, and the right end of the second rotating shaft 17 is provided with a second driving component and drives the second rotating shaft 17 to rotate through the second driving component; a plurality of second mounting holes 20 are opened on the fourth ring 16, a second flange 18 is arranged on the right side of the fourth ring 16, a plurality of second bolts 19 are threadedly connected to the second flange 18, and one end of the second bolt 19 passes through the second mounting hole 20 and is threadedly connected to the second mounting hole 20;

[0049] Specifically, in the present embodiment, the first drive assembly and the second drive assembly both include a first pulley 25, the two first pulleys 25 are respectively fixedly mounted on the left end of the first rotating shaft 9 and the right end of the second rotating shaft 17, a second pulley 26 is provided at the bottom of each first pulley 25, and a belt 27 is provided between the first pulley 25 and the second pulley 26; and further include two motors 28, the two motors 28 are respectively mounted inside the two chassis 1, and the output shafts of the motors 28 pass through the chassis 1 and are fixedly connected to one side of the second pulley 26;

[0050] In this embodiment, the two second pulleys 26 can be driven to rotate by starting the motor 28, and then the first pulley 25 is driven to rotate by the belt 27 installed at the outer end of the second pulley 26, and finally the first rotating shaft 9 and the second rotating shaft 17 are respectively driven to rotate by the first pulley 25. Moreover, the rotation speeds and directions of the two motors 28 are different, so the first rotor 3 and the second rotor 12 can be driven to rotate in different directions and at different speeds by the first rotating shaft 9 and the second rotating shaft 17.

[0051] Furthermore, because the first rotating shaft 9 and the second rotating shaft 17 are respectively installed in the two chassis 1, in order to dissipate the heat generated during the operation of the first rotating shaft 9 and the second rotating shaft 17, Figure 1-6As shown, the front sides of the two chassis 1 are movably connected to a chassis door 30 through hinges, and the bottom of the chassis door 30 and the bottom of the rear side of the chassis 1 are provided with a plurality of heat dissipation holes 31 for ventilation. The heat dissipation holes 31 can facilitate the circulation of air inside the chassis 1 with the outside, thereby achieving the effect of heat dissipation for the first rotating shaft 9 and the second rotating shaft 17.

[0052] In addition, after the appearance of the housing 2 is changed, the present invention can be easily cleaned. Figure 1-4 As shown, the top front side and the top rear side of the casing 2 are both movably connected with a cleaning door 29 through hinges. The cleaning door 29 is made of wear-resistant steel plate and has a long service life. By quickly and easily opening the cleaning door 29 and conveniently using cleaning tools, the difficulty of cleaning for the staff is reduced, which can reduce the cleaning time each time, save manpower, and extend normal production time.

[0053] Before crushing the material, it is necessary to pour the material into the housing 2. Figure 1-6 As shown, a feeding channel 21 for loading materials is provided on the right side of the casing 2, and the bottom end of the feeding channel 21 passes through the right wall of the casing 2 and is connected to the inside of the casing 2. The materials in the feeding channel 21 move downward through the feeding channel 21 and pass through the second rotor 12 to move between the plurality of fourth striking sticks 15 to complete the unloading.

[0054] And the crushed material also needs to be discharged from the inside of the housing 2 after the crushing work is completed. Figure 2 As shown, a first discharge port 22 for unloading materials is provided at the bottom of the casing 2, and a second discharge port 24 is provided at the bottom of the base 23. The second discharge port 24 is located at the bottom of the first discharge port 22, and the second discharge port 24 is communicated with the first discharge port 22. The material inside the casing 2 passes through the first discharge port 22 and the second discharge port 24 in sequence under the action of its own gravity and falls into the hopper installed at the bottom of the base 23, completing the discharge process.

[0055] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
