Description

Technical Field

[0001] The invention relates to the technical field of material crushing devices, in particular to a wet material crusher. Background Art

[0002] Wet material pulverizer is a pulverizing equipment for processing materials with high moisture content. It is suitable for occasions where materials containing moisture, such as organic waste, food residues, mud, biomass materials, etc., need to be ground into powder or fine particles. Wet material pulverizer generally includes a rotating shaft, on which a flinger is arranged. The rotating shaft drives the flinger to rotate at high speed to generate strong shear force and impact force to pulverize the material.

[0003] For example, the multifunctional semi-wet material crusher disclosed in the patent with authorization announcement number CN212524403U includes a main rotating shaft and a negative rotating shaft. The periphery of the main rotating shaft is connected to a plurality of equidistant and radially arranged knife hammer assemblies, and the secondary rotating shaft is also fixedly connected to a plurality of equidistant and radially arranged knife hammer assemblies. The knife hammer assemblies on the main rotating shaft and the knife hammer assemblies on the secondary rotating shaft rotate in opposite directions, so that the semi-wet material between the knife hammer assemblies on the main rotating shaft and the knife hammer assemblies on the negative rotating shaft is crushed due to the shearing action of the knife hammer assemblies.

[0004] Although the multifunctional semi-wet material pulverizer helps to fully rotary cut and crush the semi-wet material, during the material pulverizing process, the wet material will be thrown onto the cavity wall of the pulverizing chamber by the knife and hammer assembly. After long-term use, the thickness of the wet material adhering to the cavity wall of the pulverizing chamber will continue to increase, which will cause the effective material holding space of the pulverizing chamber to shrink and affect the feeding. At the same time, the wet material adhering to the inner wall will be in contact with the inner wall for a long time, which will also accelerate the corrosion damage of the inner wall.

[0005] Existing wet material pulverizers also provide protruding prism structures on the wall of the pulverizing chamber, so that the materials thrown onto the wall of the pulverizing chamber are more easily crushed when they come into contact with these prism structures, further improving the pulverizing effect on the materials. However, due to the provision of the prism structures, wet materials are easily stuck in the gaps between adjacent prism structures, and the wet materials stuck in the gaps are more difficult to clean and discharge, resulting in material waste. At the same time, this part of the materials will fill the gaps between two adjacent prism structures, resulting in the prism structures not protruding significantly, which will affect the pulverizing effect on the materials thrown onto the wall of the pulverizing chamber. Summary of the invention

[0006] The present invention provides a wet material pulverizer to solve the technical problem that when the pulverizer in the prior art is used to pulverize wet materials, the wet materials are easily adhered to the cavity wall of the pulverizing chamber, resulting in the materials that collide with the cavity wall of the pulverizing chamber being difficult to be crushed, thereby weakening the pulverizing effect of the pulverizer.

[0007] In order to solve the above problems, the present invention provides a wet material crusher adopting the following technical solution:

[0008] A wet material pulverizer, comprising:

[0009] A casing, wherein the casing has a crushing chamber, a rotating body is installed in the crushing chamber, and a crushing assembly is installed on the rotating body;

[0010] A plurality of strip-shaped protrusions arranged at intervals are arranged on the wall of the crushing chamber, and the space between any two adjacent strip-shaped protrusions forms a crushing groove, and a movable block capable of moving toward or away from the rotating body is arranged at the bottom of the crushing groove;

[0011] The movable block is used to move toward the rotating body to push out the wet materials adhered in the crushing groove, and the movable block is also used to move away from the rotating body to the bottom of the crushing groove;

[0012] The rotating body is provided with a scraper that can move toward or away from the cavity wall of the crushing cavity, and the scraper extends along the axis direction of the rotating body;

[0013] The scraper is used to move toward the cavity wall of the crushing cavity after the movable block pushes out the wet material in the crushing groove, so that the rotating body drives the scraper to rotate to scrape off the wet material adhering to the movable block and the strip-shaped protrusions.

[0014] By adopting the above technical solution, the movable block can push out the wet material stuck in the crushing groove, and the scraper can move toward the wall of the crushing chamber to contact the strip protrusion, and as the rotating body rotates, the wet material adhering to the strip protrusion and the wet material pushed out by the movable block are scraped off, so as to avoid the wet material adhering to the wall of the crushing chamber for a long time and causing corrosion to the wall of the crushing chamber, and at the same time, avoid the wet material being stuck in the crushing groove for a long time so that the material thrown on the wall cannot be crushed by the strip protrusion, affecting the crushing effect. At the same time, after the movable block pushes out the wet material in the crushing groove, this part of the wet material can contact with the rotating crushing component and be crushed again and then discharged from the crushing chamber, so as to avoid the material being stuck in the crushing groove and unable to be discharged, causing waste of material. After the wet material crusher is used for a long time, the strip protrusion will be worn. At this time, the movable block can also be pushed toward the middle of the crushing chamber so that the movable block protrudes from the worn strip protrusion, so that the movable block can replace the worn strip protrusion to assist the material in crushing.

[0015] Furthermore, the rotating body is provided with a slider capable of sliding in the radial direction of the rotating body, the scraper is located outside the rotating body, the scraper is connected to the slider, and the center of gravity of the slider and the scraper are located on both sides of the central axis of the rotating body;

[0016] An elastic member is connected between the slider and the rotating body, and the elastic member applies an elastic force to the slider to make the scraper away from the rotating body, and the weight of the slider is greater than the weight of the scraper;

[0017] The slider is used to overcome the force of the elastic member and drive the scraper to approach the rotating body when the rotating speed of the rotating body is higher than the set value, and the elastic member is used to drive the slider to move to move the scraper away from the rotating body when the rotating speed of the rotating body is lower than the set value.

[0018] By adopting the above technical scheme, in the process of the crushing component rotating at high speed with the rotating body to shred the material, since the slider is heavier, the slider moves away from the axis of the rotating body in the radial direction of the rotating body under the action of centrifugal force, and drives the scraper to move toward the rotating body, so that the scraper is close to the rotating body, which does not affect the normal operation of the crusher; when it is necessary to clean the cavity wall of the crushing chamber, it is only necessary to reduce the rotation speed of the rotating body to reduce the centrifugal force on the slider, and the centrifugal force on the slider is gradually smaller than the elastic force of the elastic member, the elastic member gradually recovers its deformation, and the slider gradually moves toward the axis of the rotating body, so that the scraper will gradually move away from the rotating body and move until it contacts the cavity wall of the crushing chamber. By controlling the rotation speed of the rotating body, the scraper can be moved toward or away from the cavity wall of the crushing chamber. When it is necessary to clean the cavity wall of the crushing chamber, it is only necessary to reduce the rotation speed of the rotating body, and the control method is simple.

[0019] Furthermore, a plurality of circumferentially spaced grid plates are provided on the wall of the pulverizing chamber, the grid plates comprising an arc-shaped connecting plate and a plurality of long bars connected to the arc-shaped connecting plate, the plurality of long bars extending along the axis direction of the rotating body and spaced along the arc direction of the arc-shaped connecting plate;

[0020] The grid plate is movably mounted on the wall of the crushing chamber, and each long bar is inserted into each crushing groove, and the long bar forms the movable block.

[0021] By adopting the above technical solution, the grid plate is pushed to move, so that multiple movable blocks can be driven to move in the crushing groove at the same time, without having to drive each movable block to move separately, so that the driving structure is less and the structure is simpler.

[0022] Furthermore, a plurality of rows of crushing assemblies are evenly distributed in the circumferential direction of the rotating body, and each row of crushing assemblies includes a plurality of crushing assemblies arranged at intervals along the axial direction of the rotating body;

[0023] The crushing assembly includes a mounting plate, one end of which is connected to a crushing hammer, and the other end of which is connected to a crushing knife. Among the crushing assemblies on the rotating body, the crushing hammers in some crushing assemblies are arranged toward the outside of the rotating body, and the crushing knives in other crushing assemblies are arranged toward the outside of the rotating body.

[0024] By adopting the above technical scheme, when crushing mixed wet materials such as hard blocky plant rhizomes and plant leaves rich in fiber, the breaker hammer can be used to crush the hard plant rhizomes, and the crushing knife can be used to cut off the fiber material in the plant rhizomes, which has a better crushing effect on wet materials containing different types of materials. The breaker hammer and the crushing knife are assembled into an integrated structure. During use, the crushing assembly can be adjusted to a state where the breaker hammer faces outward or the crushing knife faces outward according to the actual situation of the crushed material. When adjusting, it is only necessary to reverse the orientation of the crushing assembly without replacing a new crushing assembly. This adjustment method is simpler. The two ends of the crushing assembly can be used alternately, the wear of the breaker hammer and the crushing knife is more balanced, and the service life of the crushing assembly is longer.

[0025] Furthermore, among the multiple rows of crushing assemblies on the rotating body, each crushing assembly located in the same row has a crushing hammer facing the outside of the rotating body, or has a crushing knife facing the outside of the rotating body, and the crushing assemblies in each row with the crushing hammer facing the outside of the rotating body and the crushing assemblies in each row with the crushing knife facing the outside of the rotating body are arranged alternately in the circumferential direction of the rotating body, and the crushing assemblies with the crushing hammer facing the outside of the rotating body and the crushing assemblies with the crushing knife facing the outside of the rotating body are arranged alternately in the axial direction of the rotating body.

[0026] Furthermore, a mounting hole, a first adjustment hole, and a second adjustment hole are provided on the mounting plate of the crushing assembly, the first adjustment hole is located between the mounting hole and the crushing hammer, and the second adjustment hole is located between the mounting hole and the crushing knife;

[0027] The rotating body includes a rotating shaft and two assembly plates vertically connected to the rotating shaft, a plurality of mounting shafts arranged at intervals around the rotating shaft are connected between the two assembly plates, and a plurality of pins arranged at intervals around the rotating shaft are also connected between the two assembly plates, the pins are detachably connected between the two assembly plates, the pins correspond to the mounting shafts one by one, the pins are arranged between the rotating shaft and the corresponding mounting shafts along the radial direction of the rotating shaft, the crushing assembly is sleeved on the mounting shaft through the mounting hole, and is sleeved on the corresponding pin through the first adjustment hole or the second adjustment hole, and each mounting shaft and the corresponding pin are installed with a plurality of crushing assemblies arranged at intervals along the axial direction of the mounting shaft to form a row of crushing assemblies.

[0028] By adopting the above technical solution, when assembling the crushing assembly to the rotating body, if it is necessary to make the crushing knife in the crushing assembly face outward, the crushing assembly can be sleeved on the mounting shaft through the mounting hole, and sleeved on the pin shaft through the first adjustment hole. If it is necessary to make the crushing hammer in the crushing assembly face outward, the crushing assembly can be sleeved on the mounting shaft through the mounting hole, and sleeved on the pin shaft through the second adjustment hole. The installation method is simple. The pin shaft is detachable. When the state of the crushing assembly needs to be switched, it is only necessary to remove the pin shaft, and then move the crushing assembly to rotate the crushing assembly 180 degrees around the mounting shaft, and then pass the pin shaft through the two assembly plates and the first adjustment hole or the second adjustment hole on the crushing assembly between the two assembly plates, and then fix the pin shaft on the assembly plate.

[0029] Furthermore, a plurality of partition plates are fixedly connected to the rotating shaft, the plurality of partition plates are located between two assembly plates, the plurality of partition plates are spaced apart along the axial direction of the rotating shaft, and a gap is provided between two partition plates located at both ends of the plurality of partition plates and the mounting plates on the corresponding sides, the mounting shaft and the pin shaft both pass through the plurality of partition plates, and the crushing assembly is located between two adjacent partition plates, or between an adjacent partition plate and an assembly plate.

[0030] Furthermore, the first adjustment hole and the second adjustment hole are both arc-shaped long holes coaxially arranged with the mounting hole, and the weight of the breaker hammer is greater than the weight of the breaker knife.

[0031] By adopting the above technical solution, the first adjustment hole and the second adjustment hole are set to be arc-shaped long holes, so that the crushing assembly can swing around the installation axis at a certain angle, and because the weight of the breaker is greater than the weight of the crushing knife, when the rotating body rotates at a low speed, each time the breaker rotates with the rotating body to the top of the corresponding installation axis and then continues to rotate, the breaker will swing around the installation axis under the action of its own gravity, so that the crushing assembly hits the pin shaft through the hole walls of the first adjustment hole and the second adjustment hole, thereby producing a knocking effect on the crushing assembly itself and the rotating body, and can shake off the wet material adhering to the crushing assembly and the rotating body.

[0032] Furthermore, it also includes a power input mechanism, one end of the rotating shaft extends out of the casing and is transmission-connected to the power input mechanism, and a detachable end cover is installed on the side of the casing facing away from the power input mechanism.

[0033] By adopting the above technical solution, it is easy to remove the end cover and adjust the crushing components inside the casing.

[0034] The beneficial effect of a wet material crusher provided by the present invention is that the wet material adhering to the wall of the crushing chamber can be effectively removed through the cooperation of the movable block and the scraper, so that the strip-shaped protrusion can be fully exposed, thereby crushing the material that hits the wall of the crushing chamber, and avoiding the wet material adhering to the wall of the crushing chamber and affecting the crushing effect.

[0051] The plurality of partition plates 12 separate the mounting shaft 14 between the two assembly plates 21 into first mounting shaft sections 1401 and second mounting shaft sections 1402 which are arranged alternately in sequence. The first mounting shaft sections 1401 of two mounting shafts 14 arranged oppositely in the rotating body are connected with the crushing assembly 11, and the crushing assembly 11 on the first mounting shaft section 1401 is sleeved on the corresponding pin shaft 15 through the second adjustment hole 1106 on the mounting plate 1102, so that the crushing hammer 1101 in the crushing assembly 11 faces the outside of the rotating body.

[0053] like Figure 3 As shown, the wall of the crushing chamber 23 in the housing 2 is provided with a plurality of strip protrusions 16 arranged at intervals in the circumferential direction of the crushing chamber 23. The strip protrusions 16 extend in the left-right direction. The plurality of strip protrusions 16 are arranged at the front and rear sides of the inlet 201 and the outlet 202, respectively. The space between any two adjacent strip protrusions 16 forms a crushing groove. A grid plate is buckled on the strip protrusions 16, such as Figure 6 As shown, the grid plate includes two arc-shaped connecting plates 24 arranged at intervals in the left-right direction and a plurality of long bars 25 connected between the two arc-shaped connecting plates 24. The plurality of long bars 25 are arranged at intervals in the arc direction of the arc-shaped connecting plates 24. Each long bar 25 is inserted into each crushing groove correspondingly, and the long bar 25 forms a movable block slidably assembled in the crushing groove. A push cylinder 26 is provided on the outside of the housing 2. A push plate 27 is connected to the piston rod end of the push cylinder 26. The push plate 27 passes through the housing 2 and is connected to the grid plate. The push plate 27 extends along the radial direction of the crushing chamber 23, so that the long bars 25 in the screen plate are driven by the push cylinder 26 to reciprocate in the crushing groove along the radial direction of the crushing chamber 23.

[0054] like Figure 1 , Figure 2 As shown, both ends of the rotating shaft 7 extend out of the casing 2, and the frame 1 is provided with a first bearing seat 32 and a second bearing seat 9 on the left and right sides of the casing 2, respectively. The first bearing seat 32 and the second bearing seat 9 are both bearing seats with locking sleeves, so that the rotating shaft 7 and the first bearing seat 32 and the second bearing seat 9 are easier to disassemble. The frame 1 is also provided with a driving motor 3, and the output shaft end of the driving motor 3 is connected to a driving pulley 4. The left end of the rotating shaft 7 passes through the left side wall of the casing 2 and is inserted into the first bearing seat 32. The left end of the rotating shaft 7 is connected to a driven pulley 6. The driving pulley 4 and the driven pulley 6 are covered with a transmission belt 5. The driving motor 3 transmits power to the rotating shaft 7 through a belt transmission to drive the rotating shaft 7 to rotate.

[0055] The right side wall of the housing 2 is provided with an end cover 8 connected to the housing 2 by fixing bolts, the outer side wall of the end cover 8 is connected with a horizontal support plate 10, the support plate 10 is fixed with a support frame 33, the second bearing seat 9 is mounted on the support frame 33, the right end of the rotating shaft 7 passes through the end cover 8 and extends to the outside of the housing 2 and is inserted into the second bearing seat 9. Figure 2 As shown, a fixing plate 28 is connected to the right side wall of the housing 2 via fastening bolts, and the right end of the rotating shaft 7 is passed through the fixing plate 28 .

[0056] When the present invention is in use, the material is first fed into the crushing chamber 23 from the feed port 201, and then the drive motor 3 is started to drive the rotating body to rotate, and the crushing component 11 produces hammering, shearing and other effects on the material in the crushing chamber 23 to crush the material. The rotating crushing component 11 will also cause the material in the crushing chamber 23 to hit the cavity wall of the crushing chamber 23. The material that hits the cavity wall of the crushing chamber 23 will be crushed when it contacts the strip-shaped protrusion 16. The crushed material rebounds from the cavity wall of the crushing chamber 23 into the crushing chamber 23, and is hammered and sheared by the crushing component 11 again and thrown onto the cavity wall of the crushing chamber 23 for crushing. The above process is repeated continuously to completely crush the material in the crushing chamber 23 into a desired state.

[0057] During the crushing process, the sticky wet material will adhere to the wall of the crushing chamber 23, and some of the material will be stuck in the crushing groove, which will affect the crushing effect of the material that hits the wall of the crushing chamber 23. Therefore, when a lot of wet material adheres to the wall of the crushing chamber 23, it is necessary to clean the wall of the crushing chamber 23. At this time, the push cylinder 26 is controlled to drive the screen plate to move along the radial direction of the crushing chamber 23 toward the rotating body, so that the long rod 25 pushes out the material stuck in the crushing groove, and the pushed part of the material can fall into the crushing chamber 23 and continue to be crushed by the crushing assembly 11.

[0058] Then, the driving motor 3 is controlled to reduce the speed of the rotating body. At this time, the centrifugal force on the slider 18 on the rotating body gradually decreases, and the centrifugal force gradually cannot overcome the elastic force of the elastic member 19, so that the slider 18 moves toward the direction where the scraper 17 is located, thereby driving the scraper 17 to move toward the wall of the crushing chamber 23 until the scraper 17 contacts the strip protrusion 16. The scraper 17 scrapes off the wet materials adhered to the strip protrusion 16 and the wet materials adhered to the long rod 25 as the rotating body rotates, completing the cleaning of the wall of the crushing chamber 23. After the cleaning is completed, the push cylinder 26 drives the screen plate to reset, the driving motor 3 controls the rotating body to increase the speed, and the crusher resumes normal operation to continue crushing the material. After the crushing is completed, the second sealing plate between the crushing chamber 23 and the discharge port 202 is opened to discharge the material from the discharge port 202.

[0059] When the type of material to be crushed changes, the crushing assembly 11 can be adjusted. For example, when the wet material to be crushed is fresh feed rich in fiber material, which can only be crushed under shearing, the crushing assembly 11 is adjusted to a state where the crushing knife 1103 faces outward. At this time, it is only necessary to remove the end cover 8 together with the support plate 10, the support frame 33, and the second bearing seat 9 on the end cover 8, rotate the column of crushing assemblies 11 that need to be adjusted to the highest position of the rotating body, remove the corresponding pin 15, and use the pin 15 to gently move the crushing hammer 1101 in each crushing assembly 11 in the column, so that the crushing hammer 1101 rotates to the right below the corresponding installation shaft 14 under the action of gravity, and then pass the pin 15 through the first adjustment hole 1104 on each circular plate and each crushing assembly 11 in the column, and rotate the pin 15 so that the pin 15 is screwed on the connecting nut 13, and then adjust the crushing assembly 11 in the column to a state where the crushing knife 1103 faces outward.

[0060] When the material to be crushed contains hard blocky substances such as plant roots and stems, it is necessary to use a breaker hammer 1101 to hammer the material to achieve a better crushing effect. At this time, the crushing assembly 11 needs to be adjusted to a state where the breaker hammer 1101 faces outward. When adjusting, first rotate the column of crushing assemblies 11 that need to be adjusted to the lowest position of the rotating body, then remove the corresponding pin 15, and use the pin 15 to gently move the column of crushing assemblies 11, so that the breaker hammer 1101 rotates to the corresponding installation shaft 14 under the action of gravity, and then pass the pin 15 through the second adjustment hole 1106 on each circular plate and each crushing assembly 11 in the column, and screw the pin 15 threadably on the connecting nut 13 to complete the adjustment.

[0061] During the above-mentioned process of reversing and adjusting the crushing assembly 11, the driven pulley 6 and the first bearing seat 32 can also be removed from the rotating shaft 7, and the fixed plate 28 can be removed from the casing 2, and then the rotating body together with the crushing assembly 11 on the rotating body can be taken out of the casing 2, and each crushing assembly 11 can be adjusted separately to prevent the crushing assembly 11 from being stuck and unable to swing to the set position under the action of gravity of the breaker 1101.

[0062] The present invention can push out and scrape off the material stuck in the crushing groove by setting a movable block and a scraper, and can effectively clean the wet material adhering to the cavity wall of the crushing cavity, so as to prevent the wet material from adhering to the cavity wall of the crushing cavity and affecting the crushing effect. The crushing assembly in the present invention can be freely switched to a state where the crushing hammer faces outward or a state where the crushing knife faces outward, and the crushing assembly can be easily adjusted according to the type of wet material to be crushed, and is suitable for crushing different types of wet materials.

[0063] In this embodiment, the scraper is installed on the rotating body through a slider and an elastic member. The centrifugal force exerted on the slider is changed by controlling the rotation speed of the rotating body to control the scraper to approach or move away from the wall of the crushing chamber. In other embodiments, the scraper can be connected to the rotating body through an electric telescopic rod. At this time, the scraper can be moved closer to or away from the wall of the crushing chamber by controlling the electric telescopic rod to extend or retract.

[0064] In this embodiment, the crushing components on the rotating body are arranged as a row of crushing components with crushing hammers facing outwards and a row of crushing components with crushing knives facing outwards, which are arranged alternately in sequence. In other embodiments, all the crushing components can also be arranged with the crushing hammers facing the outside of the rotating body. In this case, the crusher is used to crush hard materials, or all the crushing components can be arranged with the crushing knives facing the outside of the rotating body. In this case, the crusher is used to crush fibrous materials that require shearing to crush.
