Description

Technical Field

[0001] The invention relates to the technical field of waste treatment equipment, in particular to a rotary crusher. Background Art

[0002] In the waste recycling process, some recyclable waste needs to be crushed before it can be better recycled. Therefore, these recyclable wastes need to be put into a crusher for crushing.

[0003] However, in the existing pulverizers, the contact area between the pulverizing blades and the object to be pulverized is relatively large, resulting in the problem of low pulverizing efficiency. In addition, the number of pulverizing blades on the same pulverizing drum is relatively small, which also leads to the problem of low pulverizing efficiency and poor pulverizing effect. In addition, the existing pulverizers lack separation operations, and it is difficult to separate small components such as screws on the object to be pulverized that can be directly recycled, which not only causes these small components that can be directly recycled to be mixed into the pulverized debris, but also increases the burden on the pulverizing drum. In addition, one end of the rotating shaft of the existing pulverizer is a driving turntable, and the other end is fixed with a pulverizing drum, so that when the pulverizing drum is working, the force-bearing parts at both ends of the rotating shaft are uniform, which easily causes the problem of the rotating shaft bending, thereby shortening the service life of the pulverizer.

[0026] Figure 1 It is a structural diagram of an embodiment of a rotary pulverizer of the present invention; Figure 2 FIG. 2 is a structural diagram of another preferred embodiment of the present invention from another perspective. Figure 1 and Figure 2 As shown, the rotary crusher provided in this embodiment includes: a crushing shell 1, a crushing drum 2, a crushing blade 3 and a rotating shaft 4. The crushing drum 2 is arranged in the crushing shell 1, and the crushing blade 3 is arranged on the crushing drum 2. At the same time, the crushing drum 2 is fixed on the rotating shaft 4, so that when the rotating shaft 4 rotates, it can drive the crushing drum 2 to rotate, so that the crushing blade 3 can crush the object to be crushed in the crushing shell 1.

[0027] Specifically, the pulverizing shell 1 is divided into an upper functional part 11 and a lower pulverizing part 12. The upper functional part 11 and the lower pulverizing part 12 are connected, so that the objects in the functional part 11 can fall into the pulverizing part 12 or the objects in the pulverizing part 12 can enter the functional part 11 in reverse. At the same time, the functional part 11 includes a feed port 111 on one side and a small component recovery port 112 on the other side. The pulverizing part 12 is arranged below the functional part 11, and the pulverizing part 12 is provided with a pulverizing chamber 121, so that the feeding operation of the objects to be pulverized can be realized from the feed port 111, and the small components that can be directly recycled can be separated separately through the small component recovery port 112, which can not only prevent the small components from being mixed into the pulverized debris, but also reduce the pulverizing burden caused by the pulverization of small components, and the structural design is more reasonable.

[0028] Specifically, the crushing drum 2 is arranged in the crushing chamber 121 and can rotate in the crushing chamber 121 along the direction from the feed port 111 to the small component recovery port 112, so that the feed port 111 is located in front of the rotation direction of the crushing drum 2, and the small component recovery port 112 is located behind the rotation direction of the crushing drum 2, so that the material to be crushed entering from the feed port 111 can follow the movement of the crushing drum 2 for as long as possible to achieve the crushing operation, and also the small components that can be directly recovered can be directly thrown into the small component recovery port 112 under the centrifugal action of the crushing drum 2, which is convenient for the small components to be recovered separately, and the structural design is more reasonable. At the same time, there are several groups of embedded hole groups 21 distributed along the axial direction on the outer wall of the crushing drum 2, and each group of embedded hole groups 21 includes several embedded holes distributed at intervals, which provides an installation basis for the subsequent arrangement of the crushing blade 3.

[0029] Specifically, the crushing blade 3 is arranged in the embedded hole, and one end of the crushing blade 3 is a blade end and extends out of the embedded hole, so that the crushing blade 3 can be stably fixed on the crushing drum 2 and rotate with the crushing drum 2, thereby realizing the crushing operation of the object to be crushed in the crushing chamber 121. In addition, the blade head end 31 of each crushing blade 3 is divided into two parts, and the two parts are staggered front and back, so that the blade head end 31 of the same crushing blade 3 can be staggered front and back in the rotation direction, and can also be staggered front and back in the axial direction of the crushing drum 2, so that the two parts of the blade head end 31 on the crushing blade 3 are centrally symmetrically arranged, thereby reducing the contact area with the object to be crushed, facilitating the crushing of the object to be crushed, and improving the crushing efficiency. At the same time, the number of blade heads used for crushing can be doubled when the number of crushing blades 3 remains unchanged, further improving the crushing efficiency and ensuring the crushing effect.

[0030] Specifically, the rotating shaft 4 is arranged on the crushing part 12 and passes through the crushing chamber 121. Both ends of the rotating shaft 4 extend out of the crushing part 12, and a crushing drum 2 is fixed to the part of the rotating shaft 4 located in the crushing chamber 121, so that when the rotating shaft 4 rotates, the crushing drum 2 can be driven to rotate, thereby realizing the crushing operation of the to-be-crushed object in the crushing chamber 121. In addition, a driving turntable 41 and a flywheel disk 42 are respectively arranged on both ends of the rotating shaft 4 extending out of the crushing part 12, so that the driving turntable 41 and the flywheel disk 42 can be symmetrically arranged with respect to the crushing drum 2, that is, the driving turntable 41 and the flywheel disk 42 can also be symmetrically distributed on the rotating shaft 4, so that the crushing drum 2 and the rotating shaft 4 are subjected to more uniform force, thereby avoiding the deformation problem of the rotating shaft 4 caused by uneven force in the case of long-term use, ensuring the normal use of the crusher, and extending the service life of the crusher.

[0031] More specifically, the feed port 111 and the small parts recovery port 112 of the functional part 11 are arranged in a "V" shape, and the lower parts of the feed port 111 and the small parts recovery port 112 are connected. At the same time, the lower parts of the feed port 111 and the small parts recovery port 112 are connected to the crushing chamber 121, which not only makes the feed port 111 and the small parts recovery port 112 arranged at an angle, facilitating the crushed materials to fall from the feed port 111 into the crushing chamber 121 by their own gravity, but also enables the small parts thrown out along the tangent of the crushing drum 2 by the centrifugal force to smoothly enter the small parts recovery port 112, and the structural design is more reasonable.

[0032] More specifically, a debris discharge port 124 is provided at the lower portion of the crushing chamber 121 of the crushing portion 12, a debris filter 125 is provided in the debris discharge port 124, and a gap is provided between the debris filter 125 and the blade end of the crushing blade 3 on the crushing drum 2, so that large pieces of material to be crushed can be blocked by the debris filter 125, ensuring that the debris discharged from the crusher after crushing are all small pieces, which is convenient for recycling and has a more reasonable structural design.

[0033] More specifically, the crushing part 12 is provided with an inspection window 122, which is connected to the crushing chamber 121, and an inspection door 123 is hinged on the inspection window 122, so that when the crusher needs maintenance after long-term use or needs repair after being damaged, it is only necessary to open the inspection door 123 to operate, which is convenient for the maintenance personnel to operate. At the same time, the hinged inspection door 123 can facilitate the maintenance personnel to open the inspection window 122, and also prevent the inspection door 123 from falling, so that the safety protection is higher and the structural design is more reasonable.

[0034] More specifically, a plurality of fixing holes 22 are provided on the edge of the crushing drum 2 along its axial direction, and one fixing hole 22 corresponds to one embedding hole group 21. At the same time, one fixing hole 22 penetrates each embedding hole of the corresponding embedding hole group 21, so that each embedding hole group 21 can be penetrated by a fixing hole 22, which facilitates the connection between the embedding holes in each embedding hole group 21 and provides an installation basis for the subsequent integrated quick installation.

[0035] More specifically, waist-shaped holes 32 are provided on the crushing blades 3. At the same time, an insertion rod 221 is provided in the fixing hole 22, and one insertion rod 221 passes through the waist-shaped hole 32 of the crushing blade 3 in the same embedding hole group 21, so that when the insertion rod 221 is inserted along the fixing hole 22, the insertion rod 221 can pass through each embedding hole of the embedding hole group 21 in turn, so that all crushing blades 3 in the group of embedding holes 21 can be installed through one insertion rod 221, and the integrated quick installation of each group of embedding holes 21 is realized, which improves the installation efficiency and facilitates maintenance and replacement.

[0036] More specifically, along the axial direction of the crushing drum 2, the crushing blades 3 are staggered in the embedded holes in two adjacent groups of embedded hole groups 21, so that the crushing blades 3 in the embedded holes in the two adjacent groups of embedded hole groups 21 can cover the length area of ​​the crushing drum 2 in the axial direction of the crushing drum 2, so that the arrangement of the crushing blades 3 can be reduced by half while ensuring the crushing effect, and at the same time, the crushing blades 3 can be staggered on the crushing drum 2, which further improves the crushing efficiency and ensures the crushing effect.

[0037] More specifically, a bending cylinder 113 is connected to the top outlet of the small component recycling port 112 of the functional part 11. The bending cylinder 113 is tilted downward, and the upper part of the bending cylinder 113 is connected to the top outlet of the small component recycling port 112, so that the small components recovered from the small component recycling port 112 can enter the bending cylinder 113 and fall downward under the action of gravity, which facilitates the recovery of small components and makes the structural design more reasonable.

[0038] More specifically, a buffer plate 1131 is hinged inside the bending cylinder 113 and at the connection between the top outlet of the small component recycling port 112 and the bending cylinder 113, and the buffer plate 1131 covers the top outlet of the small component recycling port 112, so that the buffer plate 1131 can swing at the bending cylinder 113 and the top outlet of the small component recycling port 112 to realize the opening and closing control of the top outlet, so that when small components are thrown out from the top outlet of the small component recycling port 112, the small components can be decelerated by the buffer plate 1131, and at the same time, the small components push the buffer plate 1131 to open the top outlet, so that the small components enter the bending cylinder 113 from the top outlet, thereby preventing the small components thrown out at high speed from directly impacting the bending cylinder 113 and causing damage to the bending cylinder 113, thereby extending the service life of the equipment.

[0039] More specifically, a stepped reinforcing plate is provided on the inner wall of the bending cylinder 113 and on the side of the buffer plate 1131 away from the small component recovery port 112. One side of the stepped reinforcing plate is fixed on the inner wall of the bending cylinder 113, and the other side faces the buffer plate 1131 and is provided in a serrated shape, so that a plurality of step structures are formed on the surface of the stepped reinforcing plate facing the buffer plate 1131, so that high-speed small components can be blocked by the step structure after pushing away the buffer plate 1131, so that the small components will not continue to fly and fall, and are convenient for recovery. In addition, the inner wall of the bending cylinder 113 is strengthened, so that the bending cylinder 113 can withstand greater impact force, and the structural design is more reasonable.

[0040] The rotary crusher provided in this embodiment includes a crushing shell 1, a crushing drum 2, a crushing blade 3 and a rotating shaft 4; by providing a small component recovery port 112 on the crushing shell 1, small components that can be directly recovered on the object to be crushed can be recovered separately, thereby avoiding the small components from being mixed into the crushed debris, and also reducing the crushing burden caused by the crushing of small components; in addition, the blade head end 31 of the crushing blade 3 is divided into two parts, and the two parts are staggered in front and back distribution, which effectively reduces the contact area with the object to be crushed and improves the crushing efficiency. At the same time, the blade head of the crushing blade 3 can be doubled, further improving the crushing efficiency and ensuring the crushing effect; and a driving turntable 41 and a flywheel disc 42 are respectively provided at both ends of the rotating shaft 4, thereby achieving a symmetrical distribution of the structures at both ends of the rotating shaft 4, ensuring the uniformity of the force on the crushing drum 2 and the rotating shaft 4, thereby avoiding the deformation problem caused by uneven force under long-term use, ensuring the crushing effect and extending the service life of the crusher.
