Description

Technical Field

[0001] The present application relates to the technical field of crushers, and particularly to a crusher for large-sized materials after calcination of sodium sulfide and its crushing process. Background Art

[0002] As an indispensable industrial raw material, sodium sulfide occupies an important position in the chemical industry. In the production process of sodium sulfide, calcination and crushing are crucial, which respectively affect the quality of sodium sulfide and the efficiency of subsequent processing. Among them, crushing is to change the physical form of sodium sulfide to make it easier for subsequent processing and transportation. Through a crusher, large-sized sodium sulfide materials can be transformed into smaller particles, which is not only conducive to improving production efficiency but also ensures more convenient circulation of products in the market.

[0003] There are various types of existing crushers. Among them, the impact crusher is a crushing machine that uses impact energy to crush materials, mainly including structures such as a rotor, plate hammers, and impact liners. When the machine is working, driven by an electric motor, the rotor rotates at a high speed. When the material enters the action area of the plate hammers, it impacts and breaks with the plate hammers on the rotor, and then is thrown towards the impact mechanism for further crushing. Then, it bounces back from the impact liner to the action area of the plate hammers for re-crushing. This process is repeated until the material is crushed to the required particle size and discharged from the discharge port.

[0004] However, there are still some defects in the use of existing crushers: First, a dust removal mechanism is set in the impact crusher to filter and intercept dust through a filter screen during the crushing operation. However, as the dust accumulates, the resistance becomes larger and the suction becomes smaller, thus affecting the dust removal efficiency and being unfavorable for the long-term operation of the equipment. Second, since the plate hammers are fixed to the rotor by mechanical clamping, but the part of the plate hammer extending out of the rotor wears after long-term use, and manual replacement not only wastes time, resulting in reduced work efficiency, but also wastes resources, making the unworn part of the plate hammer unable to be utilized, resulting in low utilization rate of the plate hammers. Summary of the Invention

[0005] The present application provides a crusher for large-sized materials after calcination of sodium sulfide and its crushing process, which has the advantages of fully cleaning the first filter screen and the second filter screen to improve the dust removal efficiency, and fully using the fixed hammers to improve the utilization rate, so as to solve the problem that the dust removal mechanism affects the dust removal efficiency due to dust accumulation, and solve the problem that the fixed hammers waste resources due to ineffective use.

Two movable tubes are correspondingly arranged for one movable bladder, and the two movable tubes are respectively communicated with two adjacent rotation cavities.

[0039] Further, a crushing process for a large-sized material crusher after calcination of sodium sulfide includes the following steps:

[0040] S1. When carrying out the crushing operation, first start the rotating motor to drive the rotor to rotate by the rotating shaft, then put the material into the working shell body so that the material enters from the feed port. After that, due to the high-speed rotation of the rotor, the material will be repeatedly impacted and crushed by the fixed hammer and the counterattack lining plate until the material is crushed to the required particle size and discharged from the discharge port;

[0041] S2. When carrying out the crushing operation, a positive current needs to be applied to the fixed plate to push the limiting plate to fit with the fixed hammer, so as to limit and fix the fixed hammer;

[0042] S3. When carrying out the crushing operation, part of the material falls onto the top end of the movable part and is rebounded by the elastic force of the spring, increasing the reciprocating movement frequency of the material;

[0043] S4. When performing the dust cleaning operation, first, the rotor rotates slowly, and then the moving piston is started, causing the moving shaft to drive the moving member to move. The moving member will rub against the second filter screen and impact the first filter screen to clean the dust on the first filter screen and the second filter screen.

[0044] S5. When performing the dust cleaning operation, the moving rod is driven by the moving shaft and the moving member to extend outside the dust storage box and act on the movable assembly, causing the movable assembly to generate an air flow. The air flow enters the rotating cavity of the rotor to blow the dust in the rotating cavity to move, and the dust removal mechanism cooperates with the work of the movable assembly to clean the rotating cavity and the fixed hammers therein.

[0045] S6. When performing the replacement operation, first, the rotor rotates slowly. Secondly, when the fixing assembly rotates to the front area of the dust removal mechanism, a reverse current needs to be applied to the fixing plate, causing the limiting plate to be pushed to fit with the fixing plate, thereby releasing the fixed hammer. Then, the moving piston drives the moving rod to extend, pushing the fixed hammer to rotate by a certain angle. Then, the moving piston drives the moving rod to retract. When the fixing assembly rotates out of the front area of the dust removal mechanism, a forward current needs to be applied to the fixing plate to limit and fix the fixed hammer.

[0046] The beneficial effects of the present invention are as follows:

[0047] A large - block material crusher after sodium sulfide calcination provided by the present application, by arranging a moving assembly in the dust storage box, and the moving assembly is composed of a moving piston, a moving shaft, a moving member and a moving rod. When the moving assembly works, the moving piston drives the moving shaft to work, causing the moving member to move in the dust storage box, thereby effectively rubbing the second filter screen and impacting the first filter screen, realizing the full cleaning of the dust on the first filter screen and the second filter screen, effectively and timely self - cleaning the dust removal mechanism, preventing the resistance from increasing and the suction from decreasing due to the accumulation of dust, thereby improving the dust removal efficiency, and the working shell does not need to stop to handle dust, improving the working efficiency.

[0048] By movably arranging a fixing assembly on the rotor, and the fixing assembly is composed of a fixed hammer, a fixing plate and a limiting plate. When performing the crushing operation, the limiting plate limits and fixes the fixed hammer under the action of the magnetic repulsion force of the fixing plate, enabling the fixed hammer to be stably arranged on the rotor, effectively crushing the incoming materials. When performing the replacement operation, the limiting plate releases the fixed hammer under the action of the magnetic attraction force of the fixing plate, and the moving rod is driven to extend outside the first filter screen, enabling the moving rod to push the fixed hammer to rotate by a certain angle during the slow rotation of the rotor, converting the worn side wall of the fixed hammer into a brand - new side wall of the fixed hammer, realizing the flexible conversion of the fixed hammer, thereby improving the utilization rate of the fixed hammer, and there is no need for manual replacement, saving time, and thus improving the working efficiency.

[0049] By arranging movable components on the rotor, and one movable component being located between two fixed components, when crushing operations are carried out, some materials fall onto the movable component between the two fixed components, and are pushed and rebounded under the elastic force of the movable component, effectively enhancing and improving the movement efficiency of the materials between the impact liner and the rotor, and improving the crushing effect. When dust cleaning operations are carried out, the moving rod extends to push the movable part to contract, the movable membrane is compressed, thereby effectively pushing the movable strip to squeeze the movable bladder, so that the gas in the movable bladder is discharged to the rotating cavity of the rotor through the movable pipe, to blow the dust in the rotating cavity to move, and enable the dust removal mechanism to cooperate with its work, realizing the full cleaning of the rotating cavity and the fixed hammers therein.

Detailed implementation manners

[0068] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0069] Embodiment 1, a crusher for large-sized materials after calcination of sodium sulfide, as Figures 1-3 , includes a working housing 1 for providing a working space for material crushing. Specifically, as Figure 6 , a working cavity is provided in the working housing 1, and a feed inlet is arranged at the top of the working cavity, and a discharge outlet is arranged at the bottom of the working cavity. When crushing operations are carried out, materials enter the working cavity from the feed inlet, are crushed in the working cavity, and finally are discharged from the discharge outlet of the working cavity.

[0070] As Figures 1-3 , Figure 6, on the right side of the bottom end of the working housing 1, a dust removal mechanism 3 is fixedly arranged for cleaning the dust in the working housing 1. The dust removal mechanism 3 includes a dust storage box 31, as Figures 7-8 , the outer wall of the dust storage box 31 is fixedly connected to the bottom wall surface of the working housing 1, and the dust storage box 31 is arranged at an inclination of 30 degrees, which helps to receive the dust generated in the working housing 1. One end of the dust storage box 31 located outside the working housing 1 is movably clamped with a box door 32. By disassembling the box door 32, the dust stored in the dust storage box 31 can be cleaned, so as to improve the continuous utilization rate of the dust storage box 31. The other end of the dust storage box 31 located inside the working housing 1 is fixedly clamped with a first filter screen 33, which can enable the dust in the working housing 1 to pass through the first filter screen 33 and be absorbed. The cross-sectional shape of the first filter screen 33 is arc-shaped, and the cross-sectional shape of one end of the dust storage box 31 connected to the first filter screen 33 is arc-shaped, so that the first filter screen 33 is adapted to the rotating mechanism 5, thereby better receiving the dust near the rotating mechanism 5. A second filter screen 34 is fixedly clamped on one side inside the dust storage box 31, which can filter the airflow carrying dust in the dust storage box 31, so that the dust is not stored by passing through the second filter screen 34. It should be noted that both the first filter screen 33 and the second filter screen 34 are provided with filter holes, and the diameter of the filter holes on the first filter screen 33 is larger than the diameter of the filter holes on the second filter screen 34, which helps to absorb the dust in the working housing 1 and store it in the dust storage box 31 located between the first filter screen 33 and the second filter screen 34. An air suction pump 35 is fixedly sleeved on the wall surface of the dust storage box 31 on the same side as the second filter screen 34, which can provide power airflow for dust removal in the working housing 1. In summary, when crushing operations are carried out in the working housing 1, dust removal in the working housing 1 needs to be carried out synchronously, that is, the air suction pump 35 is started to generate suction, and the dust in the working housing 1 is absorbed into the dust storage box 31, reducing the amount of dust discharged from the working housing 1 through the feed inlet and the discharge outlet, and improving environmental protection. A moving component 4 is arranged in the dust storage box 31 for fully cleaning the first filter screen 33 and the second filter screen 34, preventing the resistance from increasing and the suction from decreasing due to the accumulation of dust, thereby improving the dust removal efficiency.

[0071] as Figures 7-8, the moving component 4 includes a moving piston 41. The middle part of the cabinet door 32 is fixedly sleeved with the moving piston 41. One end of the moving shaft 42 is movably sleeved with the moving piston 41, and the other end of the moving shaft 42 is fixedly connected to the moving member 43. The moving piston 41 can be used to push the moving shaft 42 to move along the dust storage box 31, thereby driving the moving member 43 to move. The moving member 43 is composed of a horizontal strip plate and five vertical strip plates. The five vertical strip plates are longitudinally arranged on the horizontal strip plate. The first vertical strip plate contacts one side wall surface of the dust storage box 31. The second, third, and fourth vertical strip plates are located in the middle of the horizontal strip plate. The fifth vertical strip plate contacts one side wall surface of the second filter screen 34. When the vertical strip plate moves, it can effectively clean the wall surfaces of the dust storage box 31 and the second filter screen 34 by friction, so as to clean the dust on the second filter screen 34. The cross-sectional shape of the vertical strip plate is arc-shaped, and the vertical strip plate is adapted to the shape of the first filter screen 33, so that the vertical strip plate can fully impact and vibrate the first filter screen 33 to clean the dust on the first filter screen 33. In summary, when the dust cleaning operation is carried out in the dust removal mechanism 3, the moving piston 41 drives the moving shaft 42 to work, so that the moving member 43 moves in the dust storage box 31, thereby effectively rubbing the second filter screen 34 and impacting the first filter screen 33, realizing the full cleaning of the dust on the first filter screen 33 and the second filter screen 34, effectively and timely self-cleaning the dust removal mechanism 3, preventing the resistance from increasing and the suction from decreasing due to the accumulation of dust, thereby improving the dust removal efficiency, and the working housing 1 does not need to stop to handle dust, improving the working efficiency.

[0072] Embodiment 2, on the basis of Embodiment 1, a crusher for large-sized materials after calcination of sodium sulfide further includes a counterattack mechanism 2 and a rotating mechanism 5, specifically:

[0073] As Figures 2-3 , Figure 6 , on the left side of the top of the working housing 1, a counterattack mechanism 2 is fixedly arranged for impacting and crushing materials. The number of the counterattack mechanisms 2 is two. One counterattack mechanism 2 is arranged at the top of the working cavity, and the other counterattack mechanism 2 is arranged on the left side of the working cavity, so that an included angle is formed between the two counterattack mechanisms 2 and the rotating mechanism 5, effectively pushing the materials to bounce back and collide back and forth between the counterattack mechanism 2 and the rotating mechanism 5 to achieve full crushing of the materials. The counterattack mechanism 2 includes a counterattack lining plate 21. On one side wall surface of the counterattack lining plate 21 close to the rotating mechanism 5, a rack in the shape of a triangle is fixedly connected, effectively enhancing the impact force when the materials collide and improving the crushing effect. On the other side wall surface of the counterattack lining plate 21 far from the rotating mechanism 5, one end of the adjusting shaft 22 is movably clamped. Thread grooves are formed on the side wall of the adjusting shaft 22, and the adjusting shaft 22 is threadedly sleeved with the working housing 1 through the thread grooves. Two adjusting shafts 22 are correspondingly arranged for one counterattack lining plate 21, so that the counterattack lining plate 21 can be stably arranged in the working housing 1 through the adjusting shaft 22.

[0074] AsFigures 1-5 , a rotating mechanism 5 is fixedly arranged in the middle of the working housing 1 for further impacting and crushing materials. The rotating mechanism 5 includes a rotating motor 51, such as Figure 9 , a rotating motor 51 is fixedly arranged on the front side of the outer wall of the working housing 1, and a rotating housing 52 is fixedly arranged on the rear side of the outer wall of the working housing 1. Both ends of the rotating shaft 53 penetrate through the front and rear wall surfaces of the working housing 1, and one end of the rotating shaft 53 is movably connected to the rotating motor 51, and the other end of the rotating shaft 53 is movably sleeved with the rotating housing 52. When the rotating motor 51 is started, the rotating motor 51 can drive the rotating shaft 53 to rotate counterclockwise, and the rotating housing 52 can effectively limit the rotating shaft 53 and enhance the stability of the rotating shaft 53 during operation. A rotor 54 is fixedly sleeved on the side wall of the rotating shaft 53 located in the working chamber, and the shape of the rotor 54 is hexagonal prism-shaped. When the rotor 54 rotates, the side edges of the rotor 54 can impact the materials to fully crush the materials. A fixing assembly 6 is movably arranged in the side edge area of the rotor 54 for impacting the materials.

[0075] Such as Figure 9 , Figures 12-14, the fixing component 6 includes a fixing hammer 61. The fixing hammer 61 is composed of a long rod and two short rods. One short rod is movably connected to each end of the long rod. A rotating cavity is formed in the middle of the rotor 54 in the side edge area, and the rotor 54 movably sleeved the long rod through the rotating cavity. Rotating holes are formed at both ends of the rotor 54 in the side edge area, and the rotor 54 movably sleeved the short rods through the rotating holes. By arranging the long rod in the rotating cavity, the short rods in the rotating holes, and connecting the long rod and the short rods, the fixing hammer 61 can be stably arranged on the rotor 54, and the fixing hammer 61 can rotate. The cross-sectional shape of the long rod is gear-shaped, which effectively increases the multi-facetedness of the fixing hammer 61 and enhances the effect of the material hitting the fixing hammer 61. A fixing cavity is formed inside the rotor 54 below the rotating cavity, and the fixing cavity communicates with the rotating cavity. The rotor 54 is fixedly connected to the fixing plate 62 through the bottom end of the fixing cavity. The fixing plate 62 is a through electromagnet, and the magnetic property of the fixing plate 62 can be changed according to the direction of the current. The currents of the six fixing plates 62 are connected to six different power supplies, so that the six fixing plates 62 do not affect each other when energized, and thus can help to change the magnetic property of a single fixing plate 62. The limiting plate 63 is movably sleeved in the fixing cavity of the rotor 54. One end of the limiting plate 63 is adapted to the fixing hammer 61, and the other end of the limiting plate 63 is adapted to the fixing plate 62, which facilitates the limiting plate 63 to fit with the fixing hammer 61 or the fixing plate 62. The limiting plate 63 has an N-type magnetic property. When the crushing operation is carried out, the fixing plate 62 is energized with a forward current and has an N-type magnetic property. Therefore, the limiting plate 63 is repelled by the magnetic force and moves towards the fixing hammer 61, so that the limiting plate 63 is engaged with the fixing hammer 61, realizing the limiting and fixing of the fixing hammer 61 by the limiting plate 63. At this time, the fixing hammer 61 is fixed and cannot be rotated by an external force, so that the material can be stably crushed. When the replacement operation is carried out, the fixing plate 62 is energized with a reverse current and has an S-type magnetic property. Therefore, the limiting plate 63 is attracted by the magnetic force and moves towards the fixing plate 62, so that the limiting plate 63 is not engaged with the fixing hammer 61, realizing the release of the fixing hammer 61 by the limiting plate 63. At this time, the fixing hammer 61 is released and can be rotated by an external force, so that the position of the fixing hammer 61 can be rotated, and the worn side wall of the fixing hammer 61 can be converted into a brand-new side wall of the fixing hammer 61, realizing the flexible conversion of the fixing hammer 61, thereby improving the utilization rate of the fixing hammer 61, and there is no need for manual replacement, saving time, and thus improving the work efficiency. It should be noted that the moment when the fixing plate 62 is energized with a reverse current is only when the fixing hammer 61 rotates to the front area of the dust removal mechanism 3. At other times, the fixing plate 62 is still energized with a forward current.

[0076] Such as Figures 7-8, the moving component 4 further includes moving rods 44. Two moving rods 44 are fixedly connected to one side wall surface of the moving member 43 close to the first filter screen 33. The first filter screen 33 is provided with through holes, and the first filter screen 33 is movably sleeved with the moving rods 44 through the through holes. When the moving piston 41 controls the movement of the moving shaft 42, it can drive the moving member 43 to move. When the moving member 43 moves towards the first filter screen 33, it can push the moving rods 44 to penetrate through the through holes of the first filter screen 33 and extend out of the dust storage box 31, so that the moving rods 44 can act on the fixed component 6 to achieve the conversion function, or act on the movable component 7 to achieve the dust cleaning function.

[0077] Embodiment 3, on the basis of Embodiment 2, as Figure 9 , the rotating mechanism 5 further includes a movable component 7. A movable component 7 is movably arranged on the rotor 54 between the two fixed components 6 for rebounding materials.

[0078] As Figures 2-5 、 Figures 9-13 、 Figure 16, the movable component 7 includes a movable membrane 71 which is made of compressible rubber material. A movable groove is formed on the side surface of the rotor 54. One end of the movable membrane 71 is fixedly connected to the bottom end of the movable groove of the rotor 54, and the other end of the movable membrane 71 is fixedly connected to the bottom end of the movable member 72. The bottom end of the movable member 72 is flat, and the top end of the movable member 72 is arc-shaped. When the movable member 72 is not pushed by an external force, the movable membrane 71 is in an extended state, and the movable member 72 is not completely located in the movable groove. When the movable member 72 is pushed by an external force, the movable membrane 71 is in a compressed state, and the movable member 72 is completely located in the movable groove. A plurality of movable bars 73 are correspondingly arranged for one movable membrane 71. An activity cavity is formed inside the rotor 54 below the movable groove, and the activity cavity is communicated with the movable groove. The rotor 54 is movably sleeved with the movable bars 73 through the activity cavity. One end of the movable bar 73 is fixedly connected to the bottom end of the movable membrane 71, and the other end of the movable bar 73 is fixedly connected to one end of the movable bladder 74. The other end of the movable bladder 74 is fixedly connected to the bottom end of the activity cavity of the rotor 54, and a spring is arranged inside the movable bladder 74. When the movable member 72 is pushed by an external force, the movable member 72 is pushed into the movable groove, and drives the movable bar 73 to move downward, and then pushes the movable bar 73 to squeeze the movable bladder 74, so that the movable bladder 74 is compressed. When the movable member 72 is not pushed by an external force, the movable bladder 74 is extended under the action of the spring, thereby pushing the movable bar 73 to move upward, and then the movable member 72 is not completely located in the movable groove. An activity tube 75 is fixedly sleeved inside the rotor 54, and one end of the activity tube 75 is fixedly communicated with the bottom end of the movable bladder 74. The other end of the activity tube 75 is communicated with the rotation cavity of the rotor 54. Through the activity tube 75, the air flow inside the movable bladder 74 can be discharged into the rotation cavity to clean the dust inside the rotation cavity. Two activity tubes 75 are correspondingly arranged for one movable bladder 74, and the two activity tubes 75 are respectively communicated with two adjacent rotation cavities, which can enable the movable bladder 74 to act on two adjacent rotation cavities at the same time, effectively prolonging the dust removal duration of the rotation cavity.

[0079] Embodiment 4, on the basis of Embodiment 3, as Figures 1-16 , a crushing process of a large block material crusher after calcination of sodium sulfide, comprising the following steps:

[0080] S1, when carrying out the crushing operation, first start the rotation motor 51 to drive the rotor 54 to rotate by the rotation shaft 53. Then put the material into the working housing 1, so that the material enters from the feed port and moves into the working cavity. Due to the high-speed rotation of the rotor 54, the material will be impacted and crushed by the fixed hammers 61, and then thrown towards the counterattack lining plate 21 for secondary crushing. After that, it bounces back from the counterattack lining plate 21 to the fixed hammers 61 for re-crushing. This process is repeated until the material is crushed to the required particle size and discharged from the discharge port.

[0081] S2. When performing the crushing operation, a positive current needs to be applied to the fixed plate 62 to push the limiting plate 63 to fit with the fixed hammer 61, so that the fixed hammer 61 is limited and fixed, ensuring the stability of the fixed hammer 61 when crushing materials.

[0082] S3. When performing the crushing operation, some materials fall to the top of the movable part 72 and are rebounded by the elastic force of the spring, increasing the frequency of the reciprocating movement of the materials, thereby enhancing the movement efficiency of the materials between the impact lining plate 21 and the rotor 54 and improving the crushing effect.

[0083] S4. When performing the dust cleaning operation, first, the rotor 54 rotates slowly, and then the moving piston 41 is started, so that the moving shaft 42 drives the moving part 43 to move in the dust storage box 31. The moving part 43 will rub the second filter screen 34 and impact the first filter screen 33 to clean the dust on the first filter screen 33 and the second filter screen 34.

[0084] S5. When performing the dust cleaning operation, the moving rod 44 is driven by the moving shaft 42 and the moving part 43 to extend outside the dust storage box 31 and act on the movable assembly 7, causing the movable assembly 7 to generate an air flow. Specifically, the moving rod 44 pushes the movable part 72 to contract and drives the movable membrane 71 to be compressed, and then pushes the movable strip 73 to squeeze the movable bladder 74, causing the gas in the movable bladder 74 to generate an air flow and be discharged through the movable pipe 75, so that the air flow reaches the rotation cavity of the rotor 54 to blow the dust in the rotation cavity to move, and the dust removal mechanism 3 cooperates with the work of the movable assembly 7 to achieve full cleaning of the rotation cavity and the fixed hammer 61 therein.

[0085] S6. When performing the replacement operation, first, the rotor 54 rotates slowly. Secondly, if the fixing assembly 6 rotates to the front area of the dust removal mechanism 3, a reverse current needs to be applied to the fixed plate 62 to push the limiting plate 63 to fit with the fixed plate 62, so that the fixed hammer 61 is released. Then, the moving piston 41 drives the moving rod 44 to extend, pushing the fixed hammer 61 to rotate by a certain angle. Then, the moving piston 41 drives the moving rod 44 to retract. If the fixing assembly 6 rotates out of the front area of the dust removal mechanism 3, a positive current needs to be applied to the fixed plate 62 to limit and fix the fixed hammer 61. In summary, the worn side wall of the fixed hammer 61 is converted into a brand-new side wall of the fixed hammer 61, realizing the flexible conversion of the fixed hammer 61, thereby improving the utilization rate of the fixed hammer 61 and eliminating the need for manual replacement, saving time and thus improving the work efficiency.

[0086] The working principle of the usage method of the present invention is as follows:

[0087] When carrying out the crushing operation, first start the rotating motor 51 to drive the rotating shaft 53 to drive the rotor 54 to rotate. Then, feed the material into the working housing 1, so that the material enters from the feed inlet and moves into the working chamber. Due to the high-speed rotation of the rotor 54, the material will be impacted and crushed by the fixed hammers 61, and then thrown towards the counterattack lining plate 21 for secondary crushing. After that, it bounces back from the counterattack lining plate 21 to the fixed hammers 61 for re-crushing. This process repeats until the material is crushed to the required particle size and discharged from the discharge outlet. During this process, start the suction pump 35 to absorb the dust generated in the working housing 1 into the dust storage box 31 to reduce environmental pollution. At the same time, a positive current needs to be applied to the fixed plate 62 to push the limiting plate 63 to fit with the fixed hammer 61, thereby limiting and fixing the fixed hammer 61 to ensure the stability of the fixed hammer 61 when crushing the material. In addition, if some materials fall to the top of the movable part 72, they will be rebounded under the elastic force of the spring, increasing the frequency of the reciprocating movement of the material, thereby enhancing and improving the movement efficiency of the material between the counterattack lining plate 21 and the rotor 54 and improving the crushing effect.

[0088] When carrying out the dust cleaning operation, first the rotor 54 rotates slowly, and then start the moving piston 41 to drive the moving shaft 42 to drive the moving part 43 to move in the dust storage box 31. The moving part 43 will rub against the second filter screen 34 and impact the first filter screen 33 to clean the dust on the first filter screen 33 and the second filter screen 34, so as to effectively and timely self-clean the dust removal mechanism 3, prevent the resistance from increasing and the suction force from decreasing due to the accumulation of dust, thereby improving the dust removal efficiency, and the working housing 1 does not need to stop to handle the dust, improving the working efficiency. During this process, when the moving rod 44 is driven by the moving shaft 42 and the moving part 43 to extend outside the dust storage box 31, the moving rod 44 pushes the movable part 72 to contract and drives the movable membrane 71 to compress, and then pushes the movable strip 73 to squeeze the movable bladder 74, so that the gas in the movable bladder 74 generates an air flow and is discharged through the movable tube 75, making the air flow reach the rotating cavity of the rotor 54 to blow the dust in the rotating cavity to move. At this time, the suction pump 35 is continuously used to cooperate with the work of the movable assembly 7 to achieve full cleaning of the rotating cavity and the fixed hammers 61 therein, and improve the continuous utilization rate of the rotor 54 and the fixed hammers 61.

[0089] When performing the replacement operation, first, the rotor 54 rotates slowly. Secondly, when the fixing component 6 rotates to the front area of the dust removal mechanism 3, a reverse current needs to be applied to the fixing plate 62, so that the limiting plate 63 is pushed to fit with the fixing plate 62, and then the fixing hammer 61 is released. After that, the moving piston 41 drives the moving rod 44 to extend, pushing the fixing hammer 61 to rotate by a certain angle. Then, the moving piston 41 drives the moving rod 44 to retract. When the fixing component 6 rotates out of the front area of the dust removal mechanism 3, a positive current needs to be applied to the fixing plate 62 to limit and fix the fixing hammer 61. In summary, the worn side wall of the fixing hammer 61 is converted into a brand-new side wall of the fixing hammer 61, realizing the flexible conversion of the fixing hammer 61, thereby improving the utilization rate of the fixing hammer 61, and there is no need for manual replacement, saving time, and thus improving the work efficiency.
