Description

Technical Field

[0001] The utility model relates to the technical field of material crushing, in particular to a crushing and screening integrated tooling. Background Art

[0002] In industries like construction, recycling, and mining, material crushing and grading are essential components of the production process. For example, waste from demolition, ore extracted from mining, and scrap collected from recycling processes all require primary crushing to break down bulky materials into manageable chunks. After this initial crushing, the material is further processed into a powder for subsequent solidification and application.

[0003] The solidification process transforms powdered materials into a stable solid form, ensuring the material's strength and durability during use. Furthermore, to obtain the desired pellets, the crushed material must be screened to achieve different particle sizes. Furthermore, the fines return process allows the fines generated during screening to be returned to the solidification process, improving resource utilization.

[0004] However, existing crushers on the market generally face the following technical challenges: First, they often fail to achieve uniform particle size during the crushing process, resulting in varying particle sizes and compromising subsequent processing. Second, many crushers produce excessive amounts of fine powder, which not only increases material loss but also affects subsequent solidification and reuse. These combined factors severely impact production efficiency and material economy, making them unable to meet the requirements of modern processes.

[0005] Therefore, developing a crushing and screening integrated equipment with simple structure, convenient operation, high efficiency and strong adaptability can not only effectively solve the shortcomings of the existing technology, but also has important practical significance. In view of this, a crushing and screening integrated tooling is proposed. Summary of the Invention

[0006] The purpose of this utility model is to provide an integrated crushing and screening tool to address the technical issues of existing crushers, such as inconsistent particle sizes, excessive fines, low production efficiency, and insufficient processing flexibility. By integrating crushing and screening functions, this tool improves particle consistency and material utilization, while simplifying the equipment structure and enhancing overall operational efficiency and adaptability to meet the requirements of modern processes.

[0007] In order to achieve the above-mentioned purpose of the present invention, the following technical solutions are adopted:

[0008] The utility model provides an integrated crushing and screening tool, comprising a hammer machine, a crusher and a screening machine fixed to each other from top to bottom, the hammer machine is provided with a dust removal port, and also comprises a bracket, a negative pressure dust collector and a negative pressure pipe, the crusher is fixed on the bracket, the negative pressure dust collector is located on one side of the bracket, the negative pressure dust collector is provided with an air inlet, and the two ends of the negative pressure pipe are respectively fixedly connected to the dust removal port of the hammer machine and the air inlet of the negative pressure dust collector and are communicated with each other.

[0009] The principle and beneficial effects of this technical solution are as follows: the integrated crushing and screening tool in this technical solution realizes an efficient material processing process by integrating a hammer mill, a crusher and a screener. In this process, the design of the hammer mill can effectively crush large pieces of material, ensuring that the particles reach a relatively uniform particle size in the initial crushing stage. This design helps to solve the problem of uneven particle size in traditional equipment and improves the particle size consistency of the final product, thereby meeting the precision requirements of subsequent processes. At the same time, since the crushing and screening functions are integrated into one, the tooling reduces the time loss caused by multi-stage processing in traditional equipment. In the integrated design, materials do not need to be transferred between multiple devices, thereby improving the efficiency of the entire processing flow. This efficient design makes the production process smoother and significantly improves work efficiency.

[0010] Compared with the existing technology, this technical solution uses a dust removal system design in the tooling, combined with the use of a negative pressure dust collector, to effectively reduce the fine powder generated during the crushing and screening process. By setting a reasonable airflow and pressure, fine powder can be discharged and processed in a timely manner, reducing the accumulation of fine powder, improving the overall utilization rate of materials, and avoiding resource waste. At the same time, the design adopts an adjustable crushing and screening mechanism, and the tooling can flexibly cope with materials of different types and sizes. This highly adaptable feature allows users to quickly adjust equipment settings during production to meet diverse processing needs and enhance the flexibility and economy of the production line.

[0011] Furthermore, the negative pressure dust removal system integrated into the tooling design of this technical solution not only effectively controls the generation of fine dust, but also improves the working environment, reduces dust pollution, and complies with modern environmental protection requirements. This design enhances the overall environmental performance of the tooling and promotes sustainable development. Furthermore, the simplified equipment structure reduces the complexity of operation and maintenance. Users can complete material crushing and screening in a single system, reducing the need for coordination between equipment. This makes daily management and maintenance easier for operators, reduces operational difficulty, and improves equipment availability.

[0012] Furthermore, the hammer machine includes a hammer housing, an agitator for crushing materials and a motor. The agitator is located inside the hammer housing, the dust removal port is located on the hammer housing, and the hammer housing is also provided with a material inlet and a material outlet. The rotating shaft of the agitator is coaxially fixed with the transmission shaft of the motor.

[0013] Furthermore, the hammer housing comprises an upper housing and a lower housing. The material inlet and dust removal port are located in the upper housing, while the material discharge port is located in the lower housing. This design makes the equipment easier to install and maintain. The material inlet and dust removal port are located in the upper housing, while the material discharge port is located in the lower housing, which facilitates material flow and discharge and avoids blockage. The overall structure is more rational and helps improve work efficiency.

[0014] Furthermore, the upper housing is provided with a return port, which is also provided with a cover plate that covers the return port and is detachably connected to the upper housing. The return port and cover plate allow for return processing when handling certain materials, further improving material utilization and the adaptability of the equipment. The detachable design facilitates cleaning and maintenance of the return port, reducing the equipment's malfunction rate.

[0015] Furthermore, the crusher is a screen crusher, and the screen crusher is fixed below the material outlet on the hammer housing.

[0016] Furthermore, the screening machine is a linear vibrating screen equipped with a multi-layered screen structure and a collection bucket below the screen. The multi-layered screen design of the linear vibrating screen enables the equipment to simultaneously screen materials of different particle sizes, improving the efficiency and accuracy of the screening.

[0017] Furthermore, the negative pressure dust collector includes a dust collection bucket and a fan. The dust collection bucket is provided with an air inlet and an air outlet. The air outlet is fixed to the fan. The two ends of the negative pressure pipe are fixedly connected to the dust collection port of the hammer device and the air inlet of the dust collection bucket, respectively, and are connected thereto. The dust collection bucket is also provided with a filter element for filtering dust. The filter element design of the negative pressure dust collector can effectively filter dust, preventing it from entering the working environment or the interior of the equipment, thereby protecting the health of the operator and extending the service life of the equipment. The system can achieve a continuous dust removal process, ensuring that the equipment remains in good operating condition during long-term operation.

[0018] Furthermore, the dust collection bucket is equipped with a pulsed backflush filter assembly for removing dust from the filter element. This backflush assembly, particularly the pulsed backflush design, automatically removes dust from the filter element, ensuring the long-term, effective operation of the dust removal system and reducing the frequency of manual filter cleaning. This improves the automation level and ease of maintenance of the equipment while ensuring the system's dust removal efficiency, making it particularly suitable for long-term, continuous operation.

[0026] The following embodiments of the present invention will be described in detail with reference to the embodiments and examples. However, those skilled in the art will understand that the following embodiments and examples are only used to illustrate the present invention and should not be considered to limit the scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0027] The marks in the drawings of the specification include: hammer housing 1, upper housing 11, dust removal port 111, return port 112, material inlet 113, cover plate 114, lower housing 12, bracket 2, crusher 3, screening machine 4, negative pressure dust collector 5, dust removal barrel 51, filter element 511, air outlet 512, air inlet 513, fan 52, negative pressure pipe 6, manual butterfly valve 7, main shaft 8, hammer 81, fixed plate 9, through hole 9.

[0028] The utility model provides a high-efficiency integrated crushing and screening tool, as shown in the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 As shown in the figure, its carefully designed structure ensures the efficient coordination of the three major functions of crushing, screening and dust removal. The tooling is mainly composed of four key units: a support unit for stable support, a crushing unit for efficient crushing, a screening unit for fine screening, and an environmentally friendly and efficient dust removal unit. The support unit, as the cornerstone of the entire tooling, is made of high-quality stainless steel (such as 304 stainless steel) and is precisely manufactured into a sturdy bracket 2 structure. The bracket 2 not only has excellent corrosion resistance and wear resistance, but also ensures greater rigidity and hardness through a unique structural design (such as reinforcement ribs, reasonable cross-sectional shape, etc.), so that it can stably and reliably carry the heavy crushing unit and screening unit above, ensuring stability and safety in long-term operation.

[0029] The comminution unit integrates a hammer mill for initial crushing and a crusher 3 for further fine crushing. These two units are arranged in an orderly fashion from top to bottom and firmly secured to the support unit, forming a highly efficient crushing production line. The hammer mill first performs preliminary crushing on the material, after which it automatically falls into crusher 3 for more detailed crushing, effectively improving crushing efficiency and product quality.

[0030] The screening unit uses an advanced screening machine 4, which is precisely installed below the crusher 3 to ensure that the crushed material can enter smoothly and undergo fine screening. The screening machine 4 separates the material into products of different particle sizes according to the set screen aperture to meet the needs of different application scenarios.

[0031] To create a clean working environment, this technical solution is equipped with a negative pressure dust collector as a dust removal unit. This dust collector is cleverly placed on one side of the bracket 2. Through its powerful negative pressure suction, it effectively collects dust generated during the crushing and screening process, ensuring clean air, protecting the health of operators, and meeting environmental protection requirements.

[0032] Furthermore, this integrated crushing and screening tooling solution emphasizes collaborative operation and automated control between various units. Through sophisticated mechanical design and an intelligent control system, a fully automated process from material input to finished product output is achieved, significantly improving production efficiency and product quality.

[0033] Specifically, the hammer machine in the above-mentioned crushing unit includes a hammer shell 1, an agitator for crushing materials, and a motor, and the motor adopts a three-phase asynchronous motor. The hammer shell 1 includes a shell 11 and a lower shell 12. The upper shell 11 is provided with a material inlet 113, a dust removal port 111, and a return port 112. The material inlet 113 is used for the user to put the material to be crushed, and the dust removal port 111 is used to discharge the dust generated by the hammer machine when crushing the material, avoiding excessive dust deposition and affecting the crushing efficiency of the hammer machine, thereby improving its service life. The setting of the return port 112 in this technical solution allows for return processing when processing certain materials, thereby further improving the utilization rate of the material. A cover plate 114 is also provided at the return port 112. The outer contour of the cover plate 114 is rectangular. The cover plate 114 can cover the return port and is detachably connected to the upper shell 11. The detachable design also facilitates the cleaning and maintenance of the return port 112, reducing the failure rate of the equipment. In this embodiment, a discharge port is further provided on the lower shell 12, which is conducive to the fluidity and discharge of materials and avoids blockage. The overall structure is more reasonable and helps to improve work efficiency.

[0034] The agitator includes a main shaft 8 and a fixed disk 9. Hammers 81 are fixed to the main shaft 8. A corresponding number of hammers 81 can be set according to different usage scenarios. A through hole 9 is provided at the center of the fixed disk 9. The main shaft 8 can be inserted into the through hole 9 and pass through the fixed disk 9. The main shaft 8 is welded to the fixed disk 9. At the same time, the main shaft 8 is also coaxially fixed with the drive shaft of the motor, so that when the motor is working, the drive shaft of the motor rotates, thereby driving the main shaft 8 to rotate. The hammers 81 located on the main shaft 8 will collide with the material during the rotation process, thereby initially completing the crushing of the material.

[0035] The crusher 3 in the comminution unit is a screen crusher 3, which is fixed below the material outlet of the hammer mill lower housing 12. After the hammer mill performs preliminary comminution on the material, it enters the screen crusher 3 again, where it is further comminuted. This increases the accuracy of the comminution process, improves the material processing effect, and optimizes the particle size distribution after comminution, facilitating the subsequent screening process.

[0036] The screening machine 4 in the screening unit is a linear vibrating screen, which is provided with a screen and has a multi-layer structure. In this embodiment, the screen is provided with 3 layers. Of course, the user can also set different layers of screens to screen materials according to the screening requirements. Below the screen, a collection bucket is also provided in this technical solution. The collection bucket is used to collect the crushed material finally obtained after screening, so as to be used for the user's production and other needs. The multi-layer screen design of the linear vibrating screen enables the equipment to screen materials of different particle sizes at the same time, thereby improving the efficiency and accuracy of screening. After the above-mentioned screen crusher 3 further crushes the material, the re-crushed material will enter the linear vibrating screen. The linear vibrating screen will vibrate so that the material that meets the corresponding particle size falls from the screen on the vibrating screen into the collection bucket below, and finally completes the fully automated process from preliminary crushing, fine crushing and precise screening.

[0037] The negative pressure dust collector 5 in the dust removal unit is mainly used in this embodiment to absorb the dust generated by the equipment during the crushing process of the material, thereby reducing the dust accumulation inside the equipment and extending the service life of the equipment. The negative pressure dust collector 5 includes a dust removal bucket 51 and a fan 52. The dust removal bucket 51 is used to store dust. The dust removal bucket 51 is provided with an air inlet 513 and an air outlet 512, and the air outlet 512 is fixed to the fan 52. At the air inlet 513, a negative pressure pipe 6 is provided in this embodiment. The two ends of the negative pressure pipe 6 are respectively fixedly connected to the dust removal port 111 of the upper shell 11 of the above-mentioned hammer machine and the air inlet 513 of the dust removal bucket 51 itself and pass through. Through the above connection setting, the various dusts generated by the integrated tooling during material crushing will be directionally introduced into the dust removal bucket 51, thereby completing the dust collection. That is, the fan 52 absorbs the air in the dust removal barrel 51, thereby increasing the pressure in the dust removal barrel 51. Since the dust removal barrel 51 is connected to the dust removal port 111 of the hammer machine through the negative pressure pipe 6, the dust in the hammer machine is squeezed into the dust removal barrel 51 under the action of pressure.

[0038] The dust collection bucket 51 is also provided with a filter element 511 for filtering dust and a filter backflush assembly for removing dust from the filter element 511. The filter backflush assembly is a pulse backflush assembly. In addition, the present technical solution can also consider fixing a manual butterfly valve 7 below the dust collection bucket 51. When the dust collection bucket 51 has accumulated a lot of dust, the user can turn the manual butterfly valve 7 to discharge the dust in the dust collection bucket 51 in a timely manner, so that the negative pressure dust collector can continuously perform dust removal maintenance on the equipment.

[0039] In this embodiment, the filter element 511 is located at the center of the dust collection bucket 51. Of course, the user can also reasonably place it in other locations in the dust collection bucket 51 according to the dust removal needs to ensure maximum filtration efficiency and stable performance. This will not be repeated here. The dust collection bucket 51 in this embodiment innovatively integrates a high-efficiency filter element 511 for filtering dust and a pulse backflush component for removing accumulated dust on the filter element 511. The filter element 511, as the core component of the dust removal system, has a porous structure that can effectively capture and intercept dust particles in the air.

[0040] The pulse backflush assembly, a key device for maintaining the performance of filter element 511, utilizes proven pulse jet technology. This assembly comprises a pulse valve, a compressed air source, and a jet piping system. Its operating principle is as follows: When dust accumulates on the surface of filter element 511 to a certain level, the control system automatically triggers the pulse valve to open, instantly releasing high-pressure compressed air into the filter element 511 through the jet piping system. This creates a strong reverse airflow, effectively stripping and removing dust from the filter element 511. This process occurs periodically, ensuring the continuous and efficient operation of the dust collection bin 511.

[0041] In terms of specific operating steps, this technical solution follows the well-known pulse backflushing operation process: first, when the dust collector 51 is in normal working condition, dust enters through the air inlet and is captured by the filter element 511; as time goes by, the filter element 511 is gradually blocked, and when the system detects that the pressure difference of the filter element 511 reaches a preset threshold, the pulse backflushing program is automatically started; the pulse valves are opened in sequence or simultaneously to clean the filter element 511 in turn or comprehensively; after cleaning is completed, the dust collector 51 returns to normal working condition and continues to filter dust.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
