Description

Technical Field

[0001] The present application relates to a horizontal crusher, and particularly to a horizontal ultrafine crusher. Background Art

[0002] The vertical shaft ultrafine crusher (reference: Patent Authorization Publication No. CN212348945U) is mainly applied to various large, medium and small feed mills for ultrafine crushing of various coarse powder materials to achieve the required standard of ultrafine particle size. The working principle of the vertical shaft ultrafine crusher is as follows: Materials enter the crushing chamber through the feed inlet. There is a crushing disk in the crushing chamber. A plurality of hammers are circumferentially arranged at intervals on the edge of the crushing disk. A gear ring is provided in the radially outer region of the crushing disk. The crushing disk drives the hammers to rotate at high speed. The materials are crushed under the impact of the high-speed rotating hammers and the friction and shearing between the hammers and the gear ring. The crushed materials enter the material classification wheel for classification. The qualified crushed materials are sent away by the airflow generated by the fan through the discharge chamber via the material classification wheel. The unqualified crushed materials fall onto the high-speed rotating crushing disk. The materials on the crushing disk are thrown between the gear ring and the hammers under the action of centrifugal force, and are hit by the hammers again and undergo friction and shearing between the hammers and the gear ring. The rotation center of the crushing disk of the above vertical shaft ultrafine crusher is vertically arranged, and the driving mechanism of the crushing disk is arranged at the lower part and the side part of the crushing chamber at the same time. The whole equipment is tall and has a large horizontal floor area, resulting in higher manufacturing and use costs.

[0003] The patent document with the publication number CN111558439A discloses a horizontal crushing device, which is much lower in height and simpler in structure compared with the above vertical shaft ultrafine crusher. According to the content recorded in this patent document (see paragraphs 0031 - 0047 of the specification, Figure 1 ) the structure of the horizontal crushing device can be summarized as: mainly including a frame, a crushing component and a discharging component; among them, the crushing component is arranged on the frame and includes a crushing chamber housing (i.e., cylinder 1), a crushing mechanism and a crushing driving device (including a main shaft assembly 9, a coupling 10 and a main motor 11). The crushing driving device is arranged at the rear side of the crushing chamber housing. The crushing mechanism is located in the crushing chamber formed by the crushing chamber housing and is driven to operate by the crushing driving device; the discharging component is arranged at the front side of the crushing component and includes a discharging chamber housing. The discharging chamber housing is connected to the front end face of the crushing chamber housing. An discharging chamber (i.e., discharging cavity 13) is formed in the discharging chamber housing. The discharging chamber is communicated with the crushed material collection space of the crushing chamber. A classification wheel rotation driving mechanism (including a driving mechanism 15, a transmission belt 14, an output shaft 12) is also installed on the discharging chamber housing. A material classification wheel (i.e., classification impeller) is installed at one end of the classification wheel rotation driving mechanism facing the crushed material collection space.

[0004] During the independent development of the horizontal ultrafine pulverizer, the applicant found that the current horizontal pulverizers, including the horizontal pulverizing device in the above-mentioned patent documents, mainly have the following problems:

[0005] First, since the pulverizing mechanism needs to be maintained regularly (such as replacing parts), at this time, it is necessary to open the pulverizing chamber housing. For the vertical pulverizer, by arranging a set of flip cover mechanisms on the frame (refer to the "hydraulic opening mechanism" in CN212348945U), the upper cover of the pulverizing chamber housing can be opened. However, for the horizontal pulverizer, since it is not easy to arrange the flip cover mechanism on the frame and the flip cover mechanism also requires a more complex structural design, the existing horizontal pulverizers usually abandon the flip cover mechanism and use a hoisting method to assist in the disassembly of the front cover of the pulverizing chamber housing. This makes it more inconvenient to open the pulverizing chamber housing of the horizontal pulverizer and reduces the maintainability of the horizontal pulverizer.

[0006] Second, the pulverizing drive device has a large structure, resulting in a relatively large horizontal floor area of the horizontal pulverizer. Specifically, the pulverizing drive device in the above-mentioned patent documents 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 through the coupling 10, and the output shaft of the main shaft assembly 9 is connected to the pulverizing disk 6. Obviously, since the main shaft assembly 9, the coupling 10, and the main motor 11 are connected in series in sequence, the length of the entire pulverizing drive device occupies most of the overall length of the horizontal pulverizer, resulting in a relatively large horizontal floor area of the horizontal pulverizer. Almost all of the current pulverizing drive devices of horizontal pulverizers adopt the above design. The main reasons are: 1) To ensure torque capacity: Since the main motor 11 uses a commercially available standard motor, the diameter of the main shaft of the main motor 11 is relatively small and is not suitable for bearing large torques. The main shaft assembly 9 is thicker and stronger than the main shaft of the main motor 11 and can bear greater torques and is 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 (pulverizing disk), protecting the main shaft of the main motor 11 and the rotary support system of this main shaft from the influence of large loads and vibrations.

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

[0008] The first object of the present application is to provide an improved horizontal pulverizer to solve the technical problem of poor maintainability of the existing horizontal pulverizer. The second object of the present application is to provide an improved horizontal pulverizer to solve the technical problem of a relatively large horizontal floor area of the existing horizontal pulverizer. The third object of the present application is to provide an improved horizontal pulverizer to solve the technical problem of large operating noise of the existing horizontal pulverizer.

[0058] The following clearly and completely describes the present application with reference to the accompanying drawings. Those of ordinary skill in the art will be able to implement the present application based on these descriptions. Before describing the present application with reference to the accompanying drawings, it should be particularly noted that:

[0059] The technical solutions and technical features provided in each part including the following description can be combined with each other without conflict.

[0060] The embodiments of the present application involved in the following description are usually only a part of the embodiments rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative work based on these embodiments should fall within the scope of patent protection.

[0061] Regarding the terms and units in this specification: The terms "including", "comprising", "having" and any variations thereof in this specification, the corresponding claims and relevant parts are intended to cover non-exclusive inclusion. The terms "front" and "rear" are based on Figure 1 the direction. In addition, other relevant terms and units can be reasonably explained based on the relevant content provided in this specification.

[0062] Figure 1 is a schematic structural diagram of a horizontal grinder according to an embodiment of the present application. Figure 2 is Figure 1 a schematic diagram of the horizontal grinder shown in the figure from another angle. As Figure 1 - Figure 2 shown, the horizontal grinder includes: a frame 1, a discharge component 2, a crushing component 3, a shield component 4 and a feeding component 5. The following further describes these five parts with reference to the accompanying drawings.

[0063] Figure 3 The Figure 1 schematic top view of the frame in the horizontal grinder shown. Figure 4 The Figure 3 schematic bottom view of the frame shown. Combining Figure 3 - Figure 4 As shown, the above-mentioned frame 1 includes a first support portion 11 and a second support portion 12. The first support portion 11 and the second support portion 12 can move relatively forward and backward. The discharging component 2 is integrally arranged on the first support portion 11 and forms a first module with the first support portion 11. The crushing component 3 is integrally arranged on the second support portion 12 and forms a second module with the second support portion 12. Two independent parts that are detachably connected and can move relatively forward and backward after detachment are formed between the first module and the second module.

[0064] Since the frame 1 includes a first support portion 11 and a second support portion 12. The first support portion 11 and the second support portion 12 can move relatively forward and backward. The discharging component 2 is integrally arranged on the first support portion 11 and forms a first module with the first support portion 11. The crushing component 3 is integrally arranged on the second support portion 12 and forms a second module with the second support portion 12. Two independent parts that are detachably connected and can move relatively forward and backward after detachment are formed between the first module and the second module. Therefore, by separating the first module from the second module, the discharging component 2 can be separated from the crushing chamber housing 31 (the crushing chamber housing 31 will be described later) of the crushing component 3, so as to open the crushing chamber housing 31 and realize the maintenance of the crushing mechanism 32 (the crushing mechanism 32 will be described later) in the crushing chamber housing 31.

[0065] Specifically, the first support portion 11 includes a sliding seat 111 that is installed on the frame 1 and can move forward and backward. The discharging component 2 is installed on the sliding seat 111 through a support. Since the sliding seat 111 can move forward and backward on the frame 1, in this way, it is possible to avoid designing the first support portion 11 and the second support portion 12 of the frame 1 as two completely independent parts, thereby improving the integrity of the frame 1.

[0066] In this embodiment, the specific structure of the frame 1 is as follows: First, the frame 1 has a framework 121, which can be welded by square steel to form the basic part of the frame 1 (the second support part 12) to bear the weight of the entire horizontal crusher. The framework 121 is usually designed as a rectangular framework to facilitate the fabrication of the framework 121 and is also beneficial to the transportation of the horizontal crusher. In the rectangular framework, a cross beam 122 parallel to the wide side of the framework 121 can be further provided. The space between the cross beam 122 and the front wide side of the framework 121 is used to install the guide rails 123, that is, the two ends of the guide rails 123 are respectively installed on the cross beam 122 and the front wide side. The guide rails 123 are arranged in the front-back direction (i.e., the length direction of the rectangular framework), and usually two left and right guide rails 123 are provided, and the two left and right guide rails 123 are respectively close to the inner sides of the two long sides of the rectangular framework.

[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. The sliding seat 111 is installed on the above-mentioned guide rails 123 through the rolling mechanism. Moreover, the left and right sides of the sliding seat 111 should be ensured to be placed on the inner sides of the two long sides of the rectangular framework, and the sliding seat 111 is limited in the left-right direction by the two long sides of the rectangular framework. The above-mentioned rolling mechanism includes four rollers 112 distributed in a rectangle, which are composed of two rollers 112 arranged front and back on each guide rail 123. The above-mentioned guide rails 123 can be made of circular steel pipes. At the same time, the generatrix of the cylindrical surface of each roller 112 has an isosceles trapezoidal line that bulges inward, and the two hypotenuses of the trapezoidal line are respectively tangent to the cross section of the circular steel pipe, so as to achieve precise guidance. A collar 113 that is sleeved on the guide rail 123 during use can also be installed at the bottom of the sliding seat 111, so as to prevent the sliding seat 111 from falling off the frame 1.

[0068] In addition, a raised platform 124 is built on the part of the framework 121 behind the cross beam 122 to serve as the support structure for the crushing disc rotary drive motor. The support structure for the crushing disc rotary drive motor will be described later. In this embodiment, the platform 124 is a box structure made of steel plate. It should also be noted that, as Figure 3 - Figure 4 shown, a section of length is reserved between the sliding seat 111 and the platform 124 on the framework 121 for installing the crushing component 3. Specifically, it is for installing the crushing chamber housing of the crushing component 3. Since the weight of the crushing chamber housing is relatively large, a longitudinal beam 125 is further provided in the middle of the cross beam 122. The longitudinal beam 125 intersects with the cross beam 122. The front end of the longitudinal beam 125 is close to the sliding seat 111, and the rear end of the longitudinal beam 125 is connected to the rear wide side of the rectangular framework. In this way, the longitudinal beam 125, the cross beam 122 and the parts of the two long sides of the rectangular framework between the sliding seat 111 and the platform 124 are used together to bear the crushing chamber housing 31, preventing the relatively heavy crushing chamber housing from causing local deformation of the framework 121.

[0069] Figure 7 is Figure 1 the internal schematic diagram of the crushing component in the horizontal crusher shown Figure 8 is Figure 5 the rear schematic diagram of the crushing component shown Figure 9 is Figure 1 the schematic diagram of the assembly relationship between the crushing drive device, the guard component and the crushing component in the horizontal crusher shown Figure 10 is Figure 1 the partial enlarged view of the guard component in the horizontal crusher shown Figure 11 is Figure 1 the partial enlarged view of the interior of the crushing component in the horizontal crusher shown Figure 12 is Figure 1 the sectional view of the crushing drive device in the horizontal crusher shown. Combining Figure 7 - Figure 12 as shown, the crushing component 3 is arranged 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 at the rear side of the crushing chamber housing 31. The crushing mechanism 32 is located in the crushing chamber formed by the crushing chamber housing 31 and is driven to operate by the crushing drive device 33

[0070] More specifically, the crushing mechanism 32 includes a crushing disc 321 that rotates. The rotation center line of the crushing disc 321 is arranged in the front-rear direction. A plurality of hammering members 322 are circumferentially and spacedly arranged on the edge of the crushing disc 321. A gear ring 323 is installed in the crushing chamber housing 31 around the edge of the crushing disc 321. The gear ring 323 is located outside the plurality of hammering members 322 and forms a material crushing channel with the plurality of hammering members 322. The crushing drive device 33 uses a crushing disc rotation drive motor 331 (the base of the crushing disc rotation drive motor 331 is installed on the platform 124). The crushing chamber housing 31 is provided with a feed port 311 at the rear of the crushing disc 321

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

[0072] Combining Figure 11, The working principle of the above-mentioned crushing component 3 is generally as follows: After the material enters the crushing chamber through the feed port 311, it needs to pass through the material crushing channel. The crushing disc rotation drive motor 331 drives the crushing disc 321 to rotate. The crushing disc 321 drives the hammering members 322 to rotate at high speed. The material is crushed under the impact of the high-speed hammering members 322 and the friction and shearing effects between the hammering members 322 and the gear ring 323, and then enters the outer cavity C1. In the outer cavity C1, the material flows towards the center of the front part of the crushing chamber along with the conical guide cover 324 and enters the front-end return channel C3. The material turns in the front-end return channel C3, which promotes the separation of materials with different particle sizes. Part of the material flows towards the crushing area through the inner cavity C2 and the rear-end return channel C4 to achieve cyclic crushing, and part of the material flows out from the front end of the crushing chamber. Due to the setting of the conical guide cover 324, the conical guide cover 324 creates multiple cavities and channels, which prolongs the residence time of the material in the crushing chamber, increases the contact opportunity between the material and the crushing mechanism, and thus improves the crushing efficiency; at the same time, the design of different cavities and channels helps the material to be naturally classified according to the particle size, making it easier for the larger-particle-size material to return to the crushing area through the rear-end return channel C4 for secondary crushing.

[0073] In this embodiment, at least some of the multiple hammering members 323 have hammer blade mounting seats installed on the edge of the crushing disc 321 and arranged in the front-rear direction, and at least two hammer blades 322a spaced apart in the front-rear direction and installed on the hammer blade mounting seats. The main advantage of this design is that a material diversion flow channel is formed between at least two hammer blades 322a spaced apart on the hammer blade mounting seats. The material diversion flow channel can disperse and guide the material, making the material more evenly distributed on the hammering surfaces of at least two hammer blades 322a, avoiding uneven hammering caused by material concentration; in addition, the entrances of the material separation and diversion flow channels form multiple hammering edges, increasing the shearing effect on the material.

[0074] Furthermore, the shapes of the hammer blades 322a in the hammering members 323 located at different positions can be different. For example, the installation angles 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 passing through 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. In this way, it helps to improve the crushing efficiency.

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

[0076] Since the rotary drive motor 331 of the crushing disc is disposed close to the crushing chamber housing 31, the main shaft 331a of the rotary drive motor 331 of the crushing disc directly extends into the crushing chamber. The crushing disc 321 is assembled on the main shaft 331a and driven by the main shaft 331a to operate in a rotary manner. The main shaft 331a of the rotary drive motor 331 of the crushing disc and the rotary support system of the main shaft 331a meet the needs of loading the crushing disc 321 for operation. Therefore, on the basis of strengthening the main shaft 331a of the rotary drive motor 331 of the crushing disc and the rotary support system of the main shaft 331a, the main shaft 331a of the rotary drive motor 331 of the crushing disc is directly extended into the crushing chamber and assembled with the crushing disc 321, greatly shortening the length of the crushing drive device 33 and significantly improving the miniaturization and structural compactness levels of the horizontal crusher.

[0077] Specifically, a bushing 331b is further sleeved on the part of the main shaft 331a extending into the crushing chamber. The bushing 331b is detachably fixed on the main shaft 331a. A support disc 331c integrated with the bushing is provided on the side of the bushing. The crushing disc 321 is sleeved on the bushing 331b and fixed on the support disc 331c through a connecting member (usually a bolt). The main advantages of the above structure are as follows: The design of the support disc 331c can more evenly disperse the force between the crushing disc 321 and the bushing 331b, reducing stress concentration. The bushing 331b is sleeved on the main shaft 331a, which can protect the main shaft 331a from direct wear and damage. In addition, it is beneficial to standardize the design of the bushing 331b and the crushing disc 321, so that different specifications of crushing discs 32 can be used as needed.

[0078] In addition, the rear end of the bushing 331b is axially matched with the axial positioning structure on the main shaft 331a, and the front end of the bushing 331b is axially matched with a locking nut screwed on the main shaft. A key connection structure is further provided between the bushing 331b and the main shaft 331a. Usually, one or more gaskets can be provided between the locking nut and the front end face of the bushing 331b.

[0079] The rotary drive motor 331 of the crushing disc can be customized. The diameter of its main shaft 331a and the radial load-bearing capacity of the rotary support system (i.e., the front and rear bearings of the main shaft 331a) are both greater than those of the main shaft of a standard motor that outputs the same torque and speed as the rotary drive motor of the crushing disc, and also greater than the radial load-bearing capacity of the rotary support system. Due to the relatively large weight of the crushing disc 321, the main shaft 331a can be inclined in a front-high and rear-low manner (see Figure 12 ) to compensate for the deformation of the main shaft 331a.

[0080] Figure 5 is Figure 1 a schematic diagram of the discharge component in the horizontal crusher shown. Figure 6 is Figure 5 a schematic diagram of the discharge component from another angle shown. As shown in combination with Figure 5 - Figure 6 , the discharge component 2 is arranged 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. A discharge chamber is formed inside the discharge chamber housing, and the discharge chamber communicates with the crushed material collection space of the crushing chamber. A grading wheel rotary drive mechanism 22 is also installed on the discharge chamber housing 21. A material grading wheel 23 is installed at one end of the grading wheel rotary drive mechanism 22 facing the crushed material collection space. The specific structure of the material grading wheel 23 and the material grading principle are known and will not be elaborated here.

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

[0082] As mentioned above, since the rack 1 includes the first support portion 11 and the second support portion 12, the first support portion 11 and the second support portion 12 can move relative to each other front and back. The discharging component 2 is integrally arranged on the first support portion 11 and forms a first module with the first support portion 11. The crushing component 3 is integrally arranged on the second support portion 12 and forms a second module with the second support portion 12. Two independent parts that are detachably connected and can move relative to each other front and back are formed between the first module and the second module. Therefore, by disassembling the first module and the second module, the discharging component 2 can be separated from the crushing chamber housing 31 of the crushing component 3, thereby opening the crushing chamber housing 31 and realizing the maintenance of the crushing mechanism 32 in the crushing chamber housing 31. Here, by further dividing the discharging 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 discharging chamber with the first housing 211. Therefore, when the first module and the second module are disassembled, by opening the first housing 211, it is equivalent to directly opening the front end cover of the crushing chamber. In this way, the crushing mechanism 32 can be completely opened, facilitating the maintenance operation of the crushing mechanism 32.

[0083] In this embodiment, the following optimized designs are also carried out in the discharging component 2. Combining Figure 6 、 Figure 11 As shown, the first housing 211 sequentially includes a flange 211a and a diversion volute 211b in the direction from the outside to the inside along the radial direction of the first housing 211. A throat 211c extending backward is provided at the center of the diversion volute 211b. The inner wall of the diversion volute 211b is transitioned to the throat 211c by a diversion arc surface. A discharging channel is formed in the throat 211c, and the discharging channel is communicated with the discharging chamber. A material grading wheel 23 is installed at one end of the throat 211c facing the space for collecting the crushed material. A grading wheel rotation driving device 22 is installed in the second housing 212, and the material grading wheel 23 is connected to the rotating shaft of the grading wheel rotation driving mechanism 22.

[0084] The design of the diversion volute 211b and the throat 211c can reduce the resistance of the material when it turns and flows in the front-end return channel C3, promote the formation of a swirling flow of the material, and further promote the circulating flow of the material. In addition, the design of the diversion volute 211b and the throat 211c can also improve the structural strength of the first housing 211 and prevent the first housing 211 from deforming.

[0085] Among them, the grading wheel rotation driving mechanism 22 includes a grading wheel rotation driving motor 221 and a grading wheel installation driving main shaft 222. The grading wheel installation driving main shaft 222 is installed in the discharge chamber housing 21 in the front-rear direction. The grading wheel rotation driving motor 221 is installed outside the discharge chamber housing 21 and is in transmission connection with the front end of the grading wheel installation driving main shaft 222. The material grading wheel 23 is installed at the rear end of the grading wheel installation driving main shaft 222.

[0086] More specifically, as Figure 11 shown, a spoke-shaped bracket 223 is installed at one end of the throat pipe 211c facing the crushed material collection space. The radially inner part of the spoke-shaped bracket 223 is installed on the housing of the grading wheel installation driving main shaft 222. The radially outer part of the spoke-shaped bracket 223 is installed at the end of the throat pipe 221c and has a sealing flange 223a that forms a labyrinth dynamic seal fit with the rim of the material grading wheel 23. By providing the above-mentioned spoke-shaped bracket 223, not only the support for the material grading wheel 23 is realized, but also the dynamic seal fit between the end of the throat pipe 221c and the rim of the material grading wheel 23 is achieved.

[0087] As Figure 9 - Figure 10 shown, the shield component 4 is specifically arranged at 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 driving device 33 is placed in the noise reduction housing and is cooled by the internal cooling structure of the housing.

[0088] In this embodiment, the shield component is installed on the platform 124 (on the support structure of the crushing disc rotation driving motor). The top surface and side surface of the noise reduction housing 41 are composed of at least two layers of steel plates arranged at intervals.

[0089] Since the shield component 4 is arranged at the rear side of the crushing chamber housing and includes a noise reduction housing 41 and an internal cooling structure of the housing, and the crushing driving device 33 is placed in the noise reduction housing 41 and is cooled by the internal cooling structure of the housing, therefore, on the one hand, the shield component 4 plays a role in reducing the noise of the crushing driving device 33 and reducing the operating noise of the horizontal crusher, and on the other hand, it can also cool the crushing driving device through the internal cooling structure of the housing.

[0090] In an alternative embodiment, the internal cooling structure of the housing specifically includes a cooling air flow channel 42 formed by the space between the crushing driving 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 communicated with the cooling air flow channel.

[0091] Further, the cooling air flow channel 42 is communicated with the pulverizing chamber through the exhaust structure 44; a gas distribution channel communicated with the exhaust structure is arranged at the rear of the pulverizing mechanism 32 in the pulverizing chamber.

[0092] Generally speaking, when the pulverizing mechanism 32 operates, air flow needs to be introduced into the pulverizing chamber to promote the flow of materials. Since the cooling air flow channel 42 is communicated with the pulverizing chamber through the exhaust structure 44, and a gas distribution channel communicated with the exhaust structure is arranged at the rear of the pulverizing mechanism 32 in the pulverizing chamber, in this way, the air flow used for cooling the pulverizing drive device 33 in the cooling air flow channel 42 will enter the gas distribution channel of the pulverizing chamber through the exhaust structure 44, and then be distributed by the gas distribution channel and used as the air flow required by the pulverizing chamber, which can avoid the influence of the discharge of the air flow used for cooling the pulverizing drive device 33 in the cooling air flow channel 42 on the noise reduction effect of the noise reduction housing 41.

[0093] As Figure 11 shown, the gas distribution channel extends from the exhaust structure 44 to the feed inlet 311, and then extends from the feed inlet 311 to the material pulverizing channel, so that the air flow from the exhaust structure 44 is first mixed with the materials entering through the feed inlet 311 and then enters the material pulverizing channel for pulverization.

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

[0095] In an alternative embodiment, the air inlet structure 43 is arranged on the rear end face of the noise reduction housing 41. Specifically, as Figure 10 shown, the air inlet structure 43 includes an inner housing and an outer housing that are stacked and relatively movable. The inner housing and the outer housing are respectively provided with air inlet holes. When the inner housing and the outer housing move relative to each other in a first set manner, the total conduction area of the air inlet holes on the inner housing and the air inlet holes on the outer housing increases. When the inner housing and the outer housing move relative to each other in a second set manner, the total conduction area of the air inlet holes on the inner housing and the air inlet holes on the outer housing is smaller. Thus, the air intake volume of the air inlet structure 43 can be adjusted.

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

[0097] In summary, the horizontal crusher 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 relative to each other back and forth. The discharge component is integrally arranged on the first support portion and forms a first module with the first support portion. The crushing component is integrally arranged on the second support portion and forms a second module with the second support portion. Two independent parts that are detachably connected and can move relative to each other back and forth are formed between the first module and the second module. Therefore, by disassembling the first module and the second module, the discharge component can be separated from the crushing chamber housing, thereby opening the crushing chamber housing to achieve maintenance of the crushing mechanism in the crushing chamber housing, solving the technical problem of poor maintainability of existing horizontal crushers.

[0098] Second, since the rotary drive motor of the crushing disk is arranged close to the crushing chamber housing, the main shaft of the rotary drive motor of the crushing disk directly extends into the crushing chamber. The crushing disk is assembled on the main shaft and driven by the main shaft to operate in a rotary manner. The main shaft of the rotary drive motor of the crushing disk and the rotary support system of the main shaft meet the needs of loading the operation of the crushing disk. Therefore, on the basis of strengthening the main shaft of the rotary drive motor of the crushing disk and the rotary support system of the main shaft, the main shaft of the rotary drive motor of the crushing disk is directly extended into the crushing chamber and assembled with the crushing disk, greatly shortening the length of the crushing drive device, and can significantly improve the miniaturization and structural compactness level of the horizontal crusher, solving the technical problem of the relatively large horizontal floor area of existing horizontal crushers.

[0099] Third, since the shield component is arranged at the rear side of the crushing chamber housing and includes a noise reduction housing and an internal cooling structure of the housing, the crushing drive device is placed in the noise reduction housing and cooled through the internal cooling structure of the housing. Therefore, on the one hand, the shield component plays a role in reducing the noise of the crushing drive device, 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 housing, solving the technical problem of the large operating noise of existing horizontal crushers.

[0100] In addition, the horizontal crusher of the above embodiments also has many innovative designs for the specific structures of the frame, crushing component, discharge component, and shield component. The above innovations and innovative designs can be partially implemented and applied on the horizontal crusher.

[0101] The above has described the relevant content of this application. Those of ordinary skill in the art will be able to implement this application based on these descriptions. Based on the above content of this specification, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of patent protection.
