Description

Technical Field

[0001] This application relates to horizontal pulverizers, and more particularly to horizontal ultrafine pulverizers. Background Technology

[0002] The vertical shaft impact pulverizer (reference: patent authorization announcement number CN212348945U) is mainly used in various large, medium and small feed mills for ultra-fine pulverization of various coarse materials to achieve the required ultra-fine particle size. The working principle of the vertical shaft impact pulverizer is as follows: material enters the pulverizing chamber through the feed inlet. A pulverizing disc is installed in the chamber, with multiple hammers spaced circumferentially around its edge. A toothed ring is located on the radially outer area of ​​the pulverizing disc. The pulverizing disc drives the hammers to rotate at high speed. The material is pulverized by the impact of the high-speed hammers and the friction and shearing action between the hammers and the toothed ring. The pulverized material enters the material classifying wheel for classification. Qualified pulverized material is sent away through the discharge chamber by the airflow generated by the fan through the material classifying wheel. Unqualified pulverized material falls onto the high-speed rotating pulverizing disc. The material on the pulverizing disc is thrown between the toothed ring and the hammers by centrifugal force, where it is struck again by the hammers and subjected to friction and shearing between the hammers and the toothed ring. The rotation center of the grinding disc of the above-mentioned vertical shaft ultrafine pulverizer is set vertically, and the driving mechanism of the grinding disc is arranged at the bottom and side of the grinding chamber. The whole equipment is tall and occupies a large horizontal area, resulting in high manufacturing and operating costs.

[0003] Patent document CN111558439A discloses a horizontal pulverizing device, which is significantly shorter and has a simpler structure compared to the aforementioned vertical shaft ultrafine pulverizer. According to the contents of this patent document (see paragraphs 0031-0047 of the specification), Figure 1 The structure of the horizontal pulverizing device can be summarized as follows: it mainly includes a frame, a pulverizing component, and a discharge component. The pulverizing component is mounted on the frame and includes a pulverizing chamber shell (i.e., cylinder 1), a pulverizing mechanism, and a pulverizing drive device (including a main shaft assembly 9, a coupling 10, and a main motor 11). The pulverizing drive device is arranged on the rear side of the pulverizing chamber shell, and the pulverizing mechanism is located in the pulverizing chamber formed by the pulverizing chamber shell and is driven by the pulverizing drive device. The discharge component is located on the front side of the pulverizing component and includes a discharge chamber shell. The discharge chamber shell is connected to the front end face of the pulverizing chamber shell, and a discharge chamber (i.e., discharge cavity 13) is formed inside the discharge chamber shell. The discharge chamber is connected to the pulverized material collection space of the pulverizing chamber. A classifying wheel rotation drive mechanism (including a drive mechanism 15, a conveyor belt 14, and an output shaft 12) is also installed on the discharge chamber shell. A material classifying wheel (i.e., a classifying impeller) is installed at the end of the classifying wheel rotation drive mechanism facing the pulverized material collection space.

[0004] In the process of independently developing the horizontal ultrafine pulverizer, the applicant discovered that current horizontal pulverizers, including the horizontal pulverizing device in the aforementioned patent literature, mainly have the following problems:

[0005] First, since the crushing mechanism requires regular maintenance (e.g., replacing parts), it is necessary to open the crushing chamber shell. For vertical crushers, the top cover of the crushing chamber shell can be opened by arranging a flip-top mechanism on the frame (refer to the "hydraulic opening mechanism" in CN212348945U). However, for horizontal crushers, the flip-top mechanism is difficult to arrange on the frame, and it also requires a more complex structural design. Therefore, existing horizontal crushers usually abandon the flip-top mechanism and use a hoisting method to assist in the disassembly of the front cover of the crushing chamber shell. This makes opening the crushing chamber shell of the horizontal crusher more inconvenient and reduces the maintainability of the horizontal crusher.

[0006] Second, the large size of the crushing drive unit results in a large horizontal footprint for the horizontal crusher. Specifically, the crushing drive unit in the aforementioned patent document includes a main shaft assembly 9, a coupling 10, and a main motor 11. The main shaft of the main motor 11 is connected to the main shaft assembly 9 via the coupling 10, and the output shaft of the main shaft assembly 9 is connected to the crushing disc 6. Clearly, since the main shaft assembly 9, coupling 10, and main motor 11 are connected in series, the entire crushing drive unit accounts for a large portion of the overall length of the horizontal crusher, thus resulting in a large horizontal footprint for the horizontal crusher. The above design is used in the crushing drive device of most horizontal crushers at present. The main reasons are: 1) To ensure torque capacity: Since the main motor 11 uses a commercially available standard motor, the main shaft diameter of the main motor 11 is relatively small and not suitable for bearing large torque. The main shaft assembly 9 is thicker and stronger than the main shaft of the main motor 11, and can withstand greater torque, making it more suitable for high-load applications; 2) Load isolation: The main shaft assembly 9 acts as a buffer to isolate the direct connection between the main motor 11 and the final load (crushing disc), protecting the main shaft of the main motor 11 and the rotation support system of the main shaft from the effects of large loads and vibrations.

[0007] Third, the motor (i.e., the main motor 11) in the crushing drive device is exposed and is cooled by natural heat dissipation, resulting in significant noise pollution. Summary of the Invention

The second objective of this application is to provide an improved horizontal crusher that solves the technical problem of excessive horizontal footprint of existing horizontal crushers.

[0025] As a further optimization and / or instantiation of the horizontal pulverizer described in the second aspect above, a plurality of hammers are arranged circumferentially at intervals along the edge of the pulverizing disc, and a toothed ring is installed in the pulverizing chamber housing around the edge of the pulverizing disc. The toothed ring is located outside the plurality of hammers and forms a material pulverizing channel between the plurality of hammers. A feed inlet is provided on the pulverizing chamber housing at the rear of the pulverizing disc.

[0026] As a further optimization and / or instantiation of the horizontal pulverizer of the second aspect above, at least some of the plurality of hammers have hammer mounting seats mounted on the edge of the pulverizing disc and arranged in the front-back direction, and at least two hammers spaced apart on the hammer mounting seats in the front-back direction.

[0031] In the horizontal pulverizer described in the second aspect above, since the pulverizing disc rotary drive motor is located close to the pulverizing chamber housing, the main shaft of the pulverizing disc rotary drive motor extends directly into the pulverizing chamber. The pulverizing disc is mounted on the main shaft and driven by the main shaft to operate in the rotary manner. The main shaft of the pulverizing disc rotary drive motor and the rotational support system of the main shaft meet the requirements for the operation of the pulverizing disc under load. Therefore, by strengthening the main shaft of the pulverizing disc rotary drive motor and the rotational support system of the main shaft, and by directly extending the main shaft of the pulverizing disc rotary drive motor into the pulverizing chamber and assembling it with the pulverizing disc, the length of the pulverizing drive device is greatly shortened, which can significantly improve the miniaturization and structural compactness of the horizontal pulverizer.

[0036] As a further optimization and / or instantiation of the horizontal pulverizer described in the third aspect above, the air intake structure is disposed on the rear end face of the noise reduction housing.

[0037] As a further optimization and / or instantiation of the horizontal pulverizer described in the third aspect above, the air intake structure includes an inner shell and an outer shell stacked together and movable relative to each other. The inner shell and the outer shell are respectively provided with air intake holes. When the inner shell and the outer shell are movable relative to each other in a first predetermined manner, the total conduction area of ​​the air intake holes on the inner shell and the outer shell increases. When the inner shell and the outer shell are movable relative to each other in a second predetermined manner, the total conduction area of ​​the air intake holes on the inner shell and the outer shell is smaller.

[0038] As a further optimization and / or instantiation of the horizontal pulverizer described in the third aspect above, the pulverizing mechanism includes a pulverizing disc that operates in a rotary manner, the center line of rotation of the pulverizing disc being arranged along the front-to-back direction, a plurality of hammers being arranged circumferentially at intervals along the edge of the pulverizing disc, a toothed ring being installed in the pulverizing chamber housing surrounding the edge of the pulverizing disc, the toothed ring being located outside the plurality of hammers and forming a material pulverizing channel between the plurality of hammers; the pulverizing drive device is a pulverizing disc rotary drive motor; and a feed inlet is provided on the pulverizing chamber housing at the rear of the pulverizing disc.

[0058] The present application will now be clearly and completely described in conjunction with the accompanying drawings. Those skilled in the art will be able to implement the present application based on these descriptions. Before describing the present application in conjunction with the accompanying drawings, it should be particularly noted that:

[0059] The technical solutions and features provided in the various sections, including the following description, can be combined with each other without conflict. Furthermore, where possible, these technical solutions, features, and related combinations can be given specific technical subject matter and protected by relevant patents.

[0060] The embodiments of this application described below are generally only some embodiments and not all embodiments. All other embodiments obtained by those skilled in the art based on these embodiments without creative effort should fall within the scope of patent protection.

[0061] Regarding terminology and units in this specification: The terms "comprising," "including," "having," and any variations thereof in this specification, the corresponding claims, and related parts are intended to cover non-exclusive inclusion. The terms "before" and "after" are based on... Figure 1 The direction. Furthermore, other relevant terms and units can be reasonably explained based on the information provided in this manual.

[0062] Figure 1 This is a schematic diagram of the structure of a horizontal pulverizer according to an embodiment of this application. Figure 2 for Figure 1 A schematic diagram of the horizontal crusher from another angle. (See diagram below.) Figures 1-2 As shown, the horizontal crusher comprises five main parts: frame 1, discharge component 2, crushing component 3, protective cover component 4, and feeding component 5. These five parts will be further described below with reference to the accompanying drawings.

[0063] Figure 3 for Figure 1 The diagram shows the top of the frame in the horizontal crusher. Figure 4 for Figure 3 The diagram shows the bottom of the rack. (Combined with...) Figures 3-4 As shown, the frame 1 includes a first support part 11 and a second support part 12. The first support part 11 and the second support part 12 can move back and forth relative to each other. The discharge part 2 is integrally disposed on the first support part 11 and forms a first module with the first support part 11. The crushing part 3 is integrally disposed on the second support part 12 and forms a second module with the second support part 12. The first module and the second module form two independent parts that are detachably connected and can move back and forth relative to each other after disassembly.

[0064] Since the frame 1 includes a first support part 11 and a second support part 12, the first support part 11 and the second support part 12 can move back and forth relative to each other. The discharge part 2 is integrally arranged on the first support part 11 and forms a first module with the first support part 11. The crushing part 3 is integrally arranged on the second support part 12 and forms a second module with the second support part 12. The first module and the second module form two independent parts that are detachably connected and can move back and forth relative to each other after disassembly. Therefore, by separating the first module and the second module, the discharge part 2 can be separated from the crushing chamber housing 31 of the crushing part 3 (the crushing chamber housing 31 is described later), thereby opening the crushing chamber housing 31 and realizing the maintenance of the crushing mechanism 32 (the crushing mechanism 32 is described later) in the crushing chamber housing 31.

[0065] Specifically, the first support 11 includes a sliding seat 111 that is mounted on the frame 1 and can move back and forth. The discharge component 2 is mounted on the sliding seat 111 via a support. Since the sliding seat 111 can move back and forth on the frame 1, it avoids designing the first support 11 and the second support 12 of the frame 1 as two completely independent parts, thereby improving the overall integrity of the frame 1.

[0066] In this embodiment, the frame 1 has the following specific structure: First, the frame 1 has a frame 121, which can be welded from square steel, thus forming the basic part of the frame 1 (second support 12) to bear the weight of the entire horizontal crusher. The frame 121 is usually designed as a rectangular frame to facilitate its manufacture and transport. A crossbeam 122 parallel to the wide side of the frame 121 can be provided within the rectangular frame. A guide rail 123 is installed between the crossbeam 122 and the front wide side of the frame 121, with both ends of the guide rail 123 respectively installed on the crossbeam 122 and the front wide side. The guide rail 123 is arranged along the front-back direction (i.e., the length direction of the rectangular frame), typically with two guide rails 123 on the left and right sides, respectively close to the inner sides of the two long sides of the rectangular frame.

[0067] Secondly, the sliding seat 111 can be made of steel plate. A rolling mechanism is installed at the bottom of the sliding seat 111, and the sliding seat 111 is mounted on the guide rail 123 through the rolling mechanism. Furthermore, the left and right sides of the sliding seat 111 should be positioned inside the two long sides of the rectangular frame, which limit the sliding seat 111 in the left and right directions. The rolling mechanism includes four rectangularly distributed rollers 112, consisting of two rollers 112 positioned at the front and rear of each guide rail 123. The guide rail 123 can be made of circular steel pipe. The generatrix of the cylindrical surface of each roller 112 has an inwardly convex isosceles trapezoidal line, and the two hypotenuses of this trapezoidal line are tangent to the cross-section of the circular steel pipe, thus achieving precise guidance. A collar 113 can also be installed at the bottom of the sliding seat 111 to fit onto the guide rail 123 during use, thus preventing the sliding seat 111 from detaching from the frame 1.

[0068] Furthermore, a raised platform 124 is erected on the portion of frame 121 located behind the crossbeam 122 to serve as a support structure for the rotary drive motor of the pulverizing disc. The support structure for the rotary drive motor of the pulverizing disc will be described later. In this embodiment, platform 124 is a box structure made of steel plate. It should also be noted that, as... Figures 3-4 As shown, a length is reserved on the frame 121 between the sliding seat 111 and the platform 124 for installing the crushing component 3, specifically, for installing the crushing chamber shell of the crushing component 3. Because the crushing chamber shell is quite heavy, a longitudinal beam 125 is also provided in the middle of the crossbeam 122. The longitudinal beam 125 intersects with the crossbeam 122, with its front end close to the sliding seat 111 and its rear end connected to the rear wide side of the rectangular frame. In this way, the longitudinal beam 125, the crossbeam 122, and the portions of the two long sides of the rectangular frame located between the sliding seat 111 and the platform 124 are used together to support the crushing chamber shell 31, preventing the heavy crushing chamber shell from causing localized deformation of the frame 121.

Figure 8 for Figure 5 A schematic diagram of the rear of the crushing component is shown. Figure 9 for Figure 1 The diagram shows the assembly relationship between the crushing drive device, the protective cover, and the crushing components in the horizontal crusher. Figure 10 for Figure 1 A partially enlarged view of the protective cover component in the horizontal crusher shown. Figure 11 for Figure 1 The image shows a magnified view of the interior of the crushing component in the horizontal crusher. Figure 12 for Figure 1 The image shows a cross-sectional view of the crushing drive unit in the horizontal crusher. (Combined with...) Figures 7-12 As shown, the crushing component 3 is mounted on the frame 1 and includes a crushing chamber housing 31, a crushing mechanism 32, and a crushing drive device 33. The crushing drive device 33 is arranged on the rear side of the crushing chamber housing 31, and the crushing mechanism 32 is located inside the crushing chamber formed by the crushing chamber housing 31 and is driven by the crushing drive device 33.

[0070] More specifically, the crushing mechanism 32 includes a crushing disc 321 that operates in a rotary manner. The center line of rotation of the crushing disc 321 is set along the front-to-back direction. Multiple hammers 322 are arranged circumferentially around the edge of the crushing disc 321. A toothed ring 323 is installed in the crushing chamber housing 31, which surrounds the edge of the crushing disc 321. The toothed ring 323 is located outside the multiple hammers 322 and forms a material crushing channel between the multiple hammers 322. The crushing drive device 33 adopts a crushing disc rotary drive motor 331 (the base of the crushing disc rotary drive motor 331 is installed on the platform 124). A feed inlet 311 is provided on the crushing chamber housing 31 at the rear of the crushing disc 321.

[0071] In addition, a conical guide shroud 324 is provided in the grinding chamber in front of the grinding disc 321. The conical guide shroud 324 is coaxially arranged with the grinding disc 321 and extends forward at its small end. The conical guide shroud 324 is installed on the inner wall of the grinding chamber housing 31 by a bracket 325 and forms an outer cavity C1 between the conical guide shroud 324 and the inner wall of the grinding chamber housing 31. An inner cavity C2 is formed in the conical guide shroud 324. A front return channel C3 is formed between the front end of the conical guide shroud 324 and the front end face of the grinding chamber housing 31. A rear return channel C4 is provided between the conical guide shroud 324 and the grinding disc 321.

[0072] Combination Figure 11The working principle of the aforementioned crushing component 3 is roughly as follows: After the material enters the crushing chamber through the feed inlet 311, it needs to pass through the material crushing channel. The crushing disc rotation drive motor 331 drives the crushing disc 321 to rotate, and the crushing disc 321 drives the hammer 322 to rotate at high speed. The material is crushed under the impact of the high-speed hammer 322 and the friction and shearing action between the hammer 322 and the toothed ring 323, and then enters the outer cavity C1. In the outer cavity C1, the material flows towards the front center of the crushing chamber with the conical guide shroud 324 and enters the front return channel C3. The material turns in the front return channel C3, promoting the separation of materials of different particle sizes. A portion of the material flows to the crushing area through the inner cavity C2 and the rear return channel C4 to achieve circulating crushing, and a portion of the material flows out from the front of the crushing chamber. Because of the conical guide shroud 324, which creates multiple cavities and channels, the material stays in the crushing chamber for a longer period of time, increasing the contact opportunities between the material and the crushing mechanism, thereby improving the crushing efficiency. At the same time, the design of different cavities and channels helps the material to be naturally classified according to particle size, making it easier for larger particles to return to the crushing area for secondary crushing through the rear return channel C4.

[0073] In this embodiment, at least some of the plurality of hammers 323 have hammer mounting seats mounted on the edge of the crushing disc 321 and arranged in the front-back direction, and at least two hammers 322a spaced apart on the hammer mounting seats in the front-back direction. The main advantage of this design is that a material guide channel is formed between the at least two hammers 322a spaced apart on the hammer mounting seats. The material guide channel can disperse and guide the material, making the material more evenly distributed on the hammering surface of the at least two hammers 322a, avoiding uneven hammering caused by material concentration. In addition, the inlet of the material guide channel forms multiple hammering edges, increasing the shearing effect on the material.

[0074] Furthermore, the shape of the hammer blades 322a in the hammering members 323 located at different positions can be different. For example, the mounting angle of the hammer blades 322a in the hammering members 323 located at different positions (which can be defined by the angle between the normal line of the hammering surface of the hammer blade 322a and the radial line that passes through both the center of the hammer blade mounting seat where the hammer blade 322a is located and the rotation center of the crushing disc) can be different. This helps to improve the crushing efficiency.

[0075] In addition, such as Figure 11 , Figure 12As shown, as an important improvement, the pulverizing disc rotary drive motor 331 is disposed close to the pulverizing chamber housing 31, and the main shaft 331a of the pulverizing disc rotary drive motor 331 extends directly into the pulverizing chamber. The pulverizing disc 321 is mounted on the main shaft 331a and driven by the main shaft 331a to operate in the rotary manner. The main shaft 331a of the pulverizing disc rotary drive motor 331 and the rotational support system of the main shaft 331a meet the needs of the pulverizing disc 321 for operation.

[0076] Since the pulverizing disc rotary drive motor 331 is located close to the pulverizing chamber housing 31, the main shaft 331a of the pulverizing disc rotary drive motor 331 extends directly into the pulverizing chamber. The pulverizing disc 321 is mounted on the main shaft 331a and driven by the main shaft 331a to operate in the rotary manner. The main shaft 331a of the pulverizing disc rotary drive motor 331 and its rotational support system meet the requirements for the operation of the pulverizing disc 321. Therefore, by strengthening the main shaft 331a of the pulverizing disc rotary drive motor 331 and its rotational support system, and by directly extending the main shaft 331a of the pulverizing disc rotary drive motor 331 into the pulverizing chamber and mounting it with the pulverizing disc 321, the length of the pulverizing drive device 33 is greatly shortened, which can significantly improve the miniaturization and structural compactness of the horizontal pulverizer.

[0077] Specifically, the portion of the main shaft 331a extending into the grinding chamber is fitted with a bushing 331b, which is detachably fixed to the main shaft 331a. A support disc 331c, integral with the bushing, is provided on the side of the bushing. The grinding disc 321 is fitted onto the bushing 331b and fixed to the support disc 331c via a connector (usually bolts). The main advantages of this structure are: the design of the support disc 331c can more evenly distribute the force between the grinding disc 321 and the bushing 331b, reducing stress concentration; the bushing 331b, fitted onto the main shaft 331a, can protect the main shaft 331a from direct wear and damage; furthermore, it facilitates the standardized design of the bushing 331b and the grinding disc 321, allowing the use of grinding discs 32 of different specifications as needed.

[0078] Furthermore, the rear end of the bushing 331b is axially engaged with the axial positioning structure on the main shaft 331a, and the front end of the bushing 331b is axially engaged with the locking nut screwed onto the main shaft. A key connection structure is also provided between the bushing 331b and the main shaft 331a. Typically, one or more washers can be provided between the locking nut and the front end face of the bushing 331b.

[0079] The rotary drive motor 331 for the pulverizing disc can be customized. The diameter of its main shaft 331a and the radial load-bearing capacity of its rotating support system (i.e., the front and rear bearings of the main shaft 331a) are both greater than those of a standard motor with the same torque and speed output as the pulverizing disc rotary drive motor. Due to the large weight of the pulverizing disc 321, the main shaft 331a can be tilted with a higher front and lower rear (see...). Figure 12 This is to compensate for the deformation of the main shaft 331a.

[0080] Figure 5 for Figure 1 The diagram shows the discharge component of the horizontal crusher. Figure 6 for Figure 5 A schematic diagram of the discharge component from another angle. (Combined with...) Figures 5-6 As shown, the discharge component 2 is located on the front side of the crushing component 3 and includes a discharge chamber housing 21. The discharge chamber housing 21 is connected to the front end face of the crushing chamber housing 31, forming a discharge chamber inside the discharge chamber housing. The discharge chamber is connected to the crushed material collection space of the crushing chamber. A classifying wheel rotation drive mechanism 22 is also installed on the discharge chamber housing 21. A material classifying wheel 23 is installed at the end of the classifying wheel rotation drive mechanism 22 facing the crushed material collection space. The specific structure and material classification principle of the material classifying wheel 23 are known and will not be described in detail here.

[0081] In this embodiment, the discharge chamber housing 21 specifically includes: a first housing 211, which is detachably connected to the front end face of the crushing chamber housing 31 and also serves as the front end cover of the crushing chamber; and a second housing 212, which is detachably connected to the front end face of the first housing 211 and forms the discharge chamber with the first housing 211.

[0082] As mentioned earlier, since the frame 1 includes a first support part 11 and a second support part 12, the first support part 11 and the second support part 12 can move back and forth relative to each other. The discharge component 2 is integrally mounted on the first support part 11 and forms a first module with the first support part 11. The crushing component 3 is integrally mounted on the second support part 12 and forms a second module with the second support part 12. The first module and the second module form two independent parts that are detachably connected and can move back and forth relative to each other after disassembly. Therefore, by separating the first module and the second module, the discharge component 2 can be separated from the crushing chamber shell 31 of the crushing component 3, thereby opening the crushing chamber shell 31 and realizing the maintenance of the crushing mechanism 32 in the crushing chamber shell 31. Here, by further dividing the discharge chamber housing 21 into a first housing 211 and a second housing 212, the first housing 211 is detachably connected to the front end face of the crushing chamber housing 31 and also serves as the front end cover of the crushing chamber. The second housing 212 is detachably connected to the front end face of the first housing 211 and forms the discharge chamber with the first housing 211. Therefore, when the first module and the second module are separated, opening the first housing 211 is equivalent to directly opening the front end cover of the crushing chamber. In this way, the crushing mechanism 32 can be completely opened, which facilitates the maintenance and operation of the crushing mechanism 32.

[0083] In this embodiment, the following optimized designs were also implemented in the discharge component 2. Combined with... Figure 6 , Figure 11 As shown, the first housing 211 includes a flange 211a and a flow guide vortex 211b in sequence along the radial direction from the outside to the inside. The flow guide vortex 211b has a throat 211c extending backward at its center. The inner wall of the flow guide vortex 211b transitions to the throat 211c with a flow guide arc surface. A discharge channel is formed in the throat 211c, which is connected to the discharge chamber. The material classifying wheel 23 is installed at the end of the throat 211c facing the crushed material collection space. The second housing 212 is equipped with a classifying wheel rotation drive device 22, and the material classifying wheel 23 is connected to the rotating shaft of the classifying wheel rotation drive device 22.

[0084] The design of the guide vortex shell 211b and the throat 211c can reduce the resistance of the material when it turns in the front return channel C3, promote the formation of swirling flow, and thus promote the circulation of the material. In addition, the design of the guide vortex shell 211b and the throat 211c can also improve the structural strength of the first shell 211 and prevent the first shell 211 from deforming.

[0085] The grading wheel rotation drive mechanism 22 includes a grading wheel rotation drive motor 221 and a grading wheel mounting drive spindle 222. The grading wheel mounting drive spindle 222 is installed in the discharge chamber housing 21 in the front-rear direction. The grading wheel rotation drive motor 221 is installed outside the discharge chamber housing 21 and is connected to the front end of the grading wheel mounting drive spindle 222 for transmission. The material grading wheel 23 is installed at the rear end of the grading wheel mounting drive spindle 222.

[0086] More specifically, such as Figure 11 As shown, a spoke-shaped bracket 223 is installed at the end of the throat 211c facing the pulverized material collection space. The radially inner portion of the spoke-shaped bracket 223 is mounted on the housing of the classifying wheel drive shaft 222, and the radially outer portion of the spoke-shaped bracket 223 is mounted on the end of the throat 221c and has a sealing flange 223a that forms a labyrinthine dynamic seal with the rim of the material classifying wheel 23. By setting the spoke-shaped bracket 223, not only is the material classifying wheel 23 supported, but also a dynamic seal is achieved between the end of the throat 221c and the rim of the material classifying wheel 23.

[0087] like Figures 9-10 As shown, the protective cover component 4 is specifically disposed on the rear side of the crushing chamber housing 31 and includes a noise reduction housing 41 and an internal cooling structure of the housing. The crushing drive device 33 is placed inside the noise reduction housing and is cooled by the internal cooling structure of the housing.

[0088] In this embodiment, the protective cover component is mounted on platform 124 (on the support structure of the pulverizing disc rotary drive motor). The top and side surfaces of the noise-reducing housing 41 are composed of at least two layers of steel plates spaced apart.

[0089] Since the protective cover component 4 is located on the rear side of the crushing chamber shell and includes the noise reduction shell 41 and the internal cooling structure of the shell, the crushing drive device 33 is placed inside the noise reduction shell 41 and cooled by the internal cooling structure of the shell. Therefore, the protective cover component 4 plays a role in reducing the noise of the crushing drive device 33 and reducing the operating noise of the horizontal crusher. On the other hand, it can also cool the crushing drive device through the internal cooling structure of the shell.

[0090] In one optional embodiment, the internal cooling structure of the housing specifically includes a cooling airflow channel 42 formed by the gap between the crushing drive device 33 and the inner wall of the noise reduction housing, and an air intake structure 43 and an exhaust structure 44 located on the noise reduction housing and respectively communicating with the cooling airflow channel.

[0091] Furthermore, the cooling airflow channel 42 is connected to the pulverizing chamber through the exhaust structure 44; the pulverizing chamber is provided with an air distribution channel connected to the exhaust structure at the rear of the pulverizing mechanism 32.

[0092] Generally, when the crushing mechanism 32 is running, airflow needs to be introduced into the crushing chamber to promote the flow of materials. Since the cooling airflow channel 42 is connected to the crushing chamber through the exhaust structure 44, and the crushing chamber has an air distribution channel at the rear of the crushing mechanism 32 that is connected to the exhaust structure, the airflow in the cooling airflow channel 42 used for cooling the crushing drive device 33 will enter the air distribution channel of the crushing chamber through the exhaust structure 44, and then be distributed by the air distribution channel as the airflow required by the crushing chamber. This can avoid the airflow in the cooling airflow channel 42 used for cooling the crushing drive device 33 from affecting the noise reduction effect of the noise reduction housing 41.

[0093] like Figure 11 As shown, the air distribution channel extends from the exhaust structure 44 to the feed inlet 311, and then from the feed inlet 311 to the material crushing channel, so that the airflow from the exhaust structure 44 first mixes with the material entering through the feed inlet 311 before entering the material crushing channel for crushing.

[0094] In a preferred embodiment, the front end face of the noise reduction housing 41 is open and the front edge of the noise reduction housing 41 is fitted with the rear end face (rear end cover) of the crushing chamber housing 31. An air inlet is provided on the rear end face of the crushing chamber housing 31, and the air inlet serves as the exhaust structure 44.

[0095] In one optional embodiment, the air intake structure 43 is disposed on the rear end face of the noise reduction housing 41. Specifically, as shown... Figure 10 As shown, the air intake structure 43 includes an inner shell and an outer shell stacked together and movable relative to each other. The inner shell and the outer shell are each provided with an air intake hole. When the inner shell and the outer shell are movable relative to each other in a first predetermined manner, the total conductive area of ​​the air intake holes on the inner shell and the outer shell increases. When the inner shell and the outer shell are movable relative to each other in a second predetermined manner, the total conductive area of ​​the air intake holes on the inner shell and the outer shell decreases. Therefore, the air intake volume of the air intake structure 43 can be adjusted.

[0096] like Figure 2 As shown, the output end of the feeding component 5 is connected to the aforementioned feed inlet 311. The feeding component 5 specifically adopts a feeder, which is an existing device, and its function is to input materials into the feed inlet 311.

[0097] In summary, the horizontal pulverizer of the above embodiments includes three main innovations. First, since the frame includes a first support portion and a second support portion, the first support portion and the second support portion can move back and forth relative to each other. The discharge component is integrally mounted on the first support portion and forms a first module with the first support portion. The pulverizing component is integrally mounted on the second support portion and forms a second module with the second support portion. The first module and the second module form two independent parts that are detachably connected and can move back and forth relative to each other after disassembly. Therefore, by separating the first module and the second module, the discharge component can be separated from the pulverizing chamber shell, thereby opening the pulverizing chamber shell and enabling maintenance of the pulverizing mechanism in the pulverizing chamber shell, thus solving the technical problem of poor maintainability of existing horizontal pulverizers.

[0098] Secondly, since the pulverizing disc rotary drive motor is located close to the pulverizing chamber housing, the main shaft of the pulverizing disc rotary drive motor extends directly into the pulverizing chamber. The pulverizing disc is mounted on the main shaft and driven by the main shaft to operate in the rotary manner. The main shaft of the pulverizing disc rotary drive motor and its rotational support system meet the requirements for the operation of the pulverizing disc under load. Therefore, by strengthening the main shaft of the pulverizing disc rotary drive motor and its rotational support system, and by directly extending the main shaft of the pulverizing disc rotary drive motor into the pulverizing chamber to assemble with the pulverizing disc, the length of the pulverizing drive device is greatly shortened. This can significantly improve the miniaturization and structural compactness of the horizontal pulverizer and solve the technical problem of the large horizontal footprint of the existing horizontal pulverizer.

[0099] Third, since the protective cover component is located on the rear side of the crushing chamber shell and includes a noise reduction shell and an internal cooling structure, and the crushing drive device is placed inside the noise reduction shell and cooled by the internal cooling structure, the protective cover component serves to reduce the noise of the crushing drive device and lower the operating noise of the horizontal crusher. On the other hand, it can also cool the crushing drive device through the internal cooling structure, thus solving the technical problem of high operating noise in existing horizontal crushers.

[0100] Furthermore, the horizontal pulverizer described in the above embodiments features numerous innovative designs in the specific structures of the frame, pulverizing components, discharge components, and protective cover components. These innovations and designs can be partially implemented and applied in horizontal pulverizers.

[0101] The foregoing has described the relevant content of this application. Those skilled in the art will be able to implement this application based on these descriptions. All other embodiments obtained by those skilled in the art based on the foregoing content of this specification without inventive effort should fall within the scope of patent protection.
