Description

Technical Field

[0001] The present invention relates to the technical field of rock processing, and more particularly to a rock material processing device. Background Art

[0002] The crushing and grinding of rock materials are widely used in the fields of mining, building materials, geological exploration and engineering, involving the crushing and grinding of large pieces of rock raw materials into particles or powders of different sizes to meet the technical requirements of subsequent applications. Traditional crushing and grinding processes mainly rely on mechanical equipment, such as jaw crushers, ball mills, impact crushers, etc., to complete the crushing and grinding of rock materials.

[0003] In the process of crushing and grinding, a large amount of dust is generated when the rock material is crushed and ground. This dust not only causes serious pollution to the environment, but also has adverse effects on the health of operators, especially in production environments with poor airtightness. Dust particles spread through the air, which not only affects the cleanliness of the production site, but also may cause equipment failures. For example, dust accumulation on the surface of the equipment or transmission parts will increase friction and equipment wear, thereby affecting the service life of the equipment.

[0004] Traditional crushing and grinding equipment usually uses simple dust removal devices, such as bag filters or cyclone dust collectors, to deal with dust pollution. Although these devices can reduce dust diffusion to a certain extent, their dust removal efficiency is limited, especially for ultra-fine dust. The capture capacity is insufficient, which easily leads to a large number of fine particles entering the atmosphere.

[0005] With the increasing requirements for environmental protection, especially in the mining, building materials and other industries, the recovery and treatment of dust generated during crushing and grinding has become an important technical problem. At present, most companies use simple dust collection devices or partial sealing to reduce dust leakage, but these methods cannot completely solve the dust problem, especially the diffusion of dust particles below the micron level in the air, which is even more difficult to capture and recycle. How to effectively capture dust at the source and recycle it in subsequent treatment is a technical problem that urgently needs to be solved at this stage. Summary of the invention

[0034] A rock material processing equipment includes a crushing system 1, a grinding system 2, a transmission system 3, a screening system 4 and a cleaning system 5. The main function of the crushing system 1 is to perform preliminary crushing of large rocks for subsequent grinding and processing. The grinding system 2 performs secondary grinding of the rocks after preliminary crushing through a high-pressure roller mill. The function of the transmission system 3 is to transfer the preliminary crushed rock particles from the first processing chamber 11 (crushing system 1) to the second processing chamber 21 (grinding system 2). The screening system 4 is used to classify the crushed and ground rock particles according to different particle sizes to ensure that only particles that meet the specifications enter the finished product area. The cleaning system 5 is used to treat the dust generated during the crushing and grinding process to prevent the dust from overflowing and polluting the environment.

[0035] The crushing system 1 includes a first processing chamber 11 and a jaw crusher 12. The jaw crusher 12 is placed in the first processing chamber 11. The jaw crusher 12 is used to preliminarily crush large rocks. The size of the crushed particles is controlled to be 50-100 mm. A guide pipe 13 is provided in the first processing chamber 11. The guide pipe 13 is placed at the bottom of the jaw crusher 12 and corresponds to the receiving box. The pipe opening at the top of the guide pipe 13 is larger than the pipe opening at the bottom.

[0036] The large rock enters the jaw crusher 12 from the top feed port of the first processing chamber 11. The jaw plate in the jaw crusher 12 moves up and down, using a strong squeezing force to crush the rock. The crushed rock particles fall into the guide pipe and enter the holding box through the guide pipe to prepare for the next step of processing.

[0037] The grinding system 2 includes a second processing chamber 21 and a high-pressure roller mill device 22. The high-pressure roller mill device 22 is placed in the second processing chamber 21. The high-pressure roller mill device 22 grinds the rock particles after preliminary crushing, and the particle size is controlled to be 1-5 mm. A screening mechanism 23 is provided in the second processing chamber 21. The screening mechanism 23 is placed at the bottom of the high-pressure roller mill device 22. The screening mechanism 23 includes a mounting cylinder 231, a sliding sleeve 232, a screening mesh plate 233, a support frame 234 and a spring 235. The sliding sleeve 232 is placed in the mounting cylinder 231 and is slidably connected to the mounting cylinder 231. The screening mesh plate 233 is fixed in the sliding sleeve 232. The support frame 234 is fixed in the mounting cylinder 231 and is placed at the bottom of the screening mesh plate 233. The spring 235 is placed between the screening mesh plate 233 and the support frame 234 and connects the screening mesh plate 233 and the support frame 234. A material guide hopper 24 is provided in the second processing chamber 21. The material guide hopper 24 is placed between the high-pressure roller mill device 22 and the screening mechanism 23.

[0038] The high-pressure roller mill device 22 and the screening mechanism 23 together constitute the core part of the rock particle grinding and screening. The rock particles that have been initially crushed by the crushing system 1 are sent to the second processing chamber 21 through the transmission system 3. In the second processing chamber 21, the rock particles are first further ground by the high-pressure roller mill, and the size of the particles is controlled within the range of 1-5mm by rolling. The ground particles enter the screening mechanism 23 through the guide hopper 24 arranged below the high-pressure roller mill. The screening mechanism 23 separates the particle size of the particles, and the particles that meet the requirements pass through the screening mesh plate 233, and the particles that do not meet the standards are retained. After that, the screening mechanism 23 can be taken out and the particles that do not meet the standards can be processed again.

[0039] The guide hopper 24 connects the high-pressure roller mill 22 and the screening mechanism 23, and is responsible for conveying the particles crushed by the high-pressure roller mill to the screening mechanism 23. The guide hopper 24 is designed in a funnel shape, so that the particles can smoothly enter the screening mechanism 23, avoiding accumulation or blockage of particles during the conveying process. The guide hopper 24 ensures that the crushed materials enter the screening link quickly and smoothly, reducing the time that the particles stay in the device and improving the efficiency of the entire system.

[0040] The mounting cylinder 231 is the main frame for fixing the screening mechanism 23, ensuring that the screening system is stably installed in the processing room and providing sliding space for the sliding sleeve 232. The sliding sleeve 232 is slidably connected to the mounting cylinder 231, driving the screening mesh plate 233 to move up and down. Through the sliding of the sliding sleeve 232, the screening mesh plate 233 completes the screening process under the gravity and vibration of the particles. The screening mesh plate 233 is used to screen particles of different particle sizes, and only particles that meet the requirements can pass through the screening mesh plate 233 and enter the next processing link. Particles that do not meet the particle size requirements remain on the screening plate.

[0041] The support frame 234 provides bottom support for the screening mesh plate 233, ensuring that the screening mesh plate 233 does not deform when subjected to force. A spring 235 structure is provided between the support frame 234 and the screening mesh plate 233, which can provide buffering and vibration during the screening process. The spring 235 connects the screening mesh plate 233 and the support frame 234, provides up and down vibration, enhances the screening effect, and prevents the screening mesh plate 233 from being blocked by particles.

[0042] The screening mechanism 23 ensures that the ground particles are effectively screened and graded, and the particles that meet the requirements enter the finished product area through the screening mesh plate 233, while the unqualified particles are returned for re-grinding, thus avoiding the problem of particle mixing. The setting of the spring 235 device makes the screening process more flexible and helps to improve the screening efficiency.

[0043] The grinding system 2 realizes efficient grinding and accurate screening of rock particles through the organic combination of the high-pressure roller mill 22 and the screening mechanism 23. The high-pressure roller mill can provide fine and uniform particle crushing, while the screening mechanism 23 ensures the particle size classification of the ground particles. The cooperation of the sliding sleeve 232, the spring 235 and other components enhances the fluidity of the particles during the screening process, avoids particle blockage, and ensures the accuracy of the screening effect.

[0044] The transmission system 3 includes a material preparation chamber 31, a lifting chamber 32, a receiving box 33, a material pushing mechanism 34, a lifting mechanism 35 and a guide rail 36. The material preparation chamber 31 and the lifting chamber 32 are both connected to the second processing chamber 21. The material preparation chamber 31 is used for placing the receiving box 33. The material pushing mechanism 34 is used to push the receiving box 33 in the material preparation chamber 31 toward the first processing chamber 11 and the lifting chamber 32. The lifting mechanism 35 is used to move the receiving box 33 up and down in the lifting chamber 32. The lifting mechanism 35 includes a first motor 351, a rotating wheel 352, a rope 353 and a lifting platform 354. The lifting platform 354 includes a base 354a and a lifting frame 354b connected to each other. The output end of the first motor 351 is fixedly connected to the rotating wheel 352. The rope 353 connects the rotating wheel 352 and the lifting frame 354b. The lifting frame 354b and the base 354a form a placement space for placing the storage box 33.

The guide rail 36 extends from the material preparation chamber 31 to the lifting chamber 32 and can be connected to the guide bar 354c. The pushing mechanism 34 includes a first cylinder 341 and a pushing head 342. The output end of the first cylinder 341 is connected to the pushing head 342. A second cylinder 311 and a limit head 312 are provided in the material preparation chamber 31 . The output end of the second cylinder 311 is connected to the limit head 312 . The second cylinder 311 drives the limit head 312 to move back and forth and is used for cutting off and unloading the containing box 33 .

[0045] The transmission system 3 is responsible for transmitting the preliminarily crushed rock particles from the first processing chamber 11 to the second processing chamber 21 through the lifting chamber 32 for further grinding. The transmission system 3 realizes the smooth and accurate movement and up and down lifting of the receiving box 33 through the first motor 351, the pushing mechanism 34, the lifting mechanism 35 and other mechanisms. The rock particles first enter the receiving box 33 after being crushed, and the receiving box 33 is pushed into the lifting chamber 32 by the pushing mechanism 34, and then the receiving box 33 is vertically lifted to the corresponding processing position by the lifting mechanism 35, and the stable movement of the receiving box 33 is ensured by the guide bar 354c and the guide rail 36 system.

[0046] The preparation chamber 31 is an area for placing and temporarily storing the storage box 33, and is used to stably transfer the storage box 33 to the first processing chamber 11 to achieve stable reception of crushed particles. The storage box 33 is used to store the crushed rock particles and transport them safely during the transmission process. The storage box 33 is designed to ensure that the rock particles will not leak out during the transmission process. At the same time, the sliding seat 331 of the storage box 33 cooperates with the guide bar 354c of the base 354a to ensure that it remains stable during the movement and avoids dumping or leakage of materials.

[0047] The pushing mechanism 34, through the pushing action of the first cylinder 341, the pushing head 342 can push the receiving box 33 from the preparation room 31 to the first processing room 11, or push it from the first processing room 11 to the lifting room 32, which improves the transmission efficiency and reduces manual operation. The lifting room 32 is a space for the receiving box 33 to be lifted vertically after entering from the first processing room 11. It realizes the up and down movement of materials through cooperation with the lifting mechanism 35. The sliding connection between the lifting room 32, the receiving box 33 and the lifting mechanism 35 ensures that the receiving box 33 has a stable operating environment when it is lifted vertically, and prevents tilting or jamming during the lifting process.

[0048] The lifting mechanism 35 is responsible for vertically lifting the containing box 33 from the lifting chamber 32 to the vicinity of the second processing chamber 21. The lifting mechanism 35 includes a first motor 351, a rotating wheel 352, a rope 353 and a lifting platform 354, wherein the first motor 351 drives the rotating wheel 352, and the rotating wheel 352 drives the rope 353 to rise or fall, thereby realizing the up and down movement of the lifting platform 354. The lifting mechanism 35 realizes the precise up and down movement of the containing box 33 through the control of the first motor 351, ensuring that the materials can be transported quickly and safely.

[0049] The lifting platform 354 is composed of a base 354a and a lifting frame 354b, forming a space for placing the storage box 33. A guide bar 354c is provided on the base 354a to cooperate with the sliding seat 331 of the storage box 33 to ensure the moving stability of the storage box 33 on the lifting platform 354. The lifting platform 354 keeps the storage box 33 stable during the lifting process, so that the material does not deviate or tip over during the movement. The cooperation between the guide bar 354c and the sliding seat 331 ensures that the storage box 33 maintains smooth movement during the movement, avoiding the jamming problem caused by excessive friction.

[0050] The guide rail 36 extends from the material preparation chamber 31 to the lifting chamber 32, and docks with the guide bar 354c of the lifting platform 354, providing guidance for the horizontal and vertical sliding of the receiving box 33. The design of the guide rail 36 and the guide bar 354c ensures that the receiving box 33 can move smoothly and steadily during the entire transmission process, avoiding the swing or tilt of the receiving box 33 during the transmission process, which helps to improve the stability of the system and the transmission efficiency.

[0051] A plurality of storage boxes 33 are stacked in the material preparation chamber 31, and the second cylinder 311 drives the limit head 312 to realize the cut-off and material discharge control of the storage box 33. The limit head 312 disengages the storage box 33, and the storage box 33 falls downward and is pushed into the first processing chamber 11 through the material pushing mechanism 34. The limit head 312 can control the moving position of the storage box 33 and ensure that there will be no material overflow or premature discharge during material discharge. The limit head 312 can automatically stop or start the transmission of the storage box 33 to ensure that the storage box 33 stably receives the crushed particles.

The screening cabinet 41 is provided with a discharge port.

[0053] The screening system 4 is responsible for screening and grading the rock particles that have been crushed and ground. The screening system 4 realizes the screening, grading, transmission and discharge functions of the materials through the coordinated work of the screening assembly 42, the second motor 422, the spiral feeding device 43 and other components.

[0054] After the rock particles are crushed, they first enter the screening component 42 in the receiving box 33, and the screening mesh disk 421 performs preliminary screening on the particles, and the particles that meet the particle size requirements enter the screening cabinet 41 through the discharge port. The screening mesh disk 421 is fixed in the receiving box 33 and is used to screen the rock particles by particle size. The rock particles that have been crushed are screened through the mesh disk, and the particles that meet the standards pass through the mesh holes, and the particles that do not meet the standards remain on the mesh disk. The screening mesh disk 421 can accurately control the particle size classification of the particles to ensure that the screening process is efficient and accurate. By adjusting the size of the mesh aperture, it can meet the screening requirements of different particle sizes, ensure that the final product has a uniform particle size, and avoid mixing too large or too small particles into the finished product. The second motor 422 is fixed to the bottom of the screening mesh disk 421, responsible for driving the eccentric wheel 423 to rotate. The eccentric wheel 423 is connected to the output end of the second motor 422, and drives the disturbance rod 424 by rotation to disturb the granular material on the screening mesh disk 421, ensuring that the material can fully contact the mesh disk and be effectively screened. The eccentric wheel 423 and the disturbance rod 424 enhance the fluidity of the particles during the screening process through vibration and disturbance, avoid material blockage, improve screening accuracy and efficiency, and ensure that the particles pass through the screen evenly.

[0055] The top of the storage box 33 is provided with a material receiving port, the bottom is provided with a material discharging port, and the screening material mesh plate 421 is fixed inside the storage box 33. The storage box 33 is used as a closed space for the screening process to load and screen the crushed materials. The design of the storage box 33 ensures the continuity and stability of material screening. The material is received through the top material receiving port. After screening, the particles that meet the requirements enter the screening cabinet 41 through the material discharging port. The sealing of the storage box 33 also effectively reduces the loss or spillage of materials.

[0056] The screening cabinet 41 receives qualified particles after screening by the screening mesh plate 421, and temporarily stores these particles in the screening cabinet 41 so that the materials can be transported to subsequent processing steps through the feeding device 43. The screening cabinet 41 serves as a transfer station for particles, and can temporarily store the materials screened from the first processing chamber 11 and the second processing chamber 21 to ensure the stability of the screening and transmission process.

[0057] The first receiving hopper 44 and the second receiving hopper 45 correspond to the material input of the first processing chamber 11 and the second processing chamber 21 respectively. The receiving hopper is used to ensure that the material can be smoothly transferred from the processing chamber to the screening cabinet 41 without overflow or accumulation. The receiving hopper can flexibly adapt to the different material sources of the two processing chambers, ensure the rapid introduction of the material into the screening cabinet 41, and avoid the loss and blockage problems during the material transmission process.

[0058] The feeding device 43 includes a third motor 431 and a spiral blade 432, which are used to transport the screened qualified particles from the screening cabinet 41 to the next stage or processing equipment. The third motor 431 drives the spiral blade 432 to rotate, and the blade pushes the material along the discharge port of the screening cabinet 41 through the rotation to achieve continuous transportation. The spiral feeding device 43 can efficiently and stably transport the screened materials, reduce the need for manual handling, and ensure the uniformity and stability of the materials during the transmission process. The precise control of the third motor 431 ensures the adjustability of the feeding process and adapts to different material conveying speed requirements. A discharge port is provided at the bottom of the screening cabinet 41, which is connected to the feeding device 43. The screened materials are transported and discharged through the discharge port by the spiral blade 432.

[0060] The cleaning system 5 is designed to clean and absorb dust and other tiny foreign matter in the crushing and grinding process through the cooperation of the fan 53, the adsorption device 52 and the pipeline 54, to prevent pollution and keep the working environment clean. The cleaning system 5 sucks the dust and foreign matter from the first processing chamber 11 and the second processing chamber 21 into the cleaning cabinet 51 through the pipeline 54, and uses water film filtration and multi-stage filter screen 521 to effectively adsorb and clean the dust. The fan 53 generates negative pressure suction to ensure the effective recovery of dust. The entire system filters the dust at multiple levels through the action of water, filter screen and guide plate 55 to achieve the purpose of environmental protection and cleaning.

[0061] The cleaning cabinet 51 is a device for collecting and processing dust and foreign matter. It contains water and uses a water film filter and adsorption device 52 for multi-layer filtration. A nozzle can also be provided in the cleaning cabinet 51 to spray water in a mist form to achieve effective adsorption of foreign matter in the space. Dust and foreign matter enter the cleaning cabinet 51 through the pipeline 54 system, and are finally processed after multiple purifications of water and filter nets. The water in the cleaning cabinet 51 captures dust and foreign matter in the air through the water film, greatly reducing dust spillage and air pollution. The water film filtration can also process finer dust particles, increasing the purification effect of the entire system.

[0062] The adsorption device 52 is located inside the cleaning cabinet 51 and includes a plurality of filter screens 521. The function of the filter screens 521 is to further adsorb fine dust and foreign matter to prevent them from overflowing through the cleaning cabinet 51. The filter screens 521 are detachably connected to the cleaning cabinet 51, which is convenient for regular cleaning and maintenance. The filter screens 521 provide multi-stage filtration and increase filtration efficiency. At the same time, the detachable design of the filter screens 521 makes maintenance work more convenient and ensures long-term and efficient operation of the system.

[0063] The fan 53 is connected to the cleaning cabinet 51, and generates negative pressure suction through the air suction port, so that dust and foreign matter are sucked into the cleaning cabinet 51 through the pipe 54. The suction force of the fan 53 ensures that dust and particulate matter will not leak out in the air, ensuring the efficiency of the cleaning process. The fan 53 provides a stable negative pressure environment through strong suction force, ensuring that dust and foreign matter can smoothly enter the cleaning cabinet 51 from the first processing chamber 11, the second processing chamber 21 and the screening cabinet 41 through the pipe 54. At the same time, the use of the fan 53 reduces the diffusion of dust during the cleaning process and improves the cleaning effect of the entire system.

[0064] The main pipe 543 collects dust from the first processing chamber 11, the second processing chamber 21 and the screening cabinet 41, and the branch pipe 544 introduces dust and foreign matter into the filtering system inside the cleaning cabinet 51. The pipeline 54 system ensures the efficient transmission of dust and foreign matter, and realizes the unified treatment of dust in multiple processing chambers through a reasonable layout of the pipeline 54 (such as the first connecting pipe 541 and the second connecting pipe 542). The reasonable design of each pipeline 54 ensures smooth air circulation and unobstructed dust transmission, which helps to improve the cleaning efficiency.

[0065] The guide plate 55 is located at the top of the cleaning cabinet 51 and is inclined. The guide plate 55 is designed to guide dust and foreign matter into the water film filtration area and control the flow direction of the airflow to ensure that the dust in the air is fully in contact with the water and the filter. The design of the guide plate 55 effectively optimizes the airflow path, increases the contact area between the dust, water and the filter, and improves the filtration efficiency. At the same time, the inclined design helps to reduce the vortex phenomenon in the airflow, avoid dust retention in the cleaning cabinet 51, and ensure the smooth flow of the airflow and the purification effect.

[0066] The branch pipe 544 is connected to the main pipe 543, and the other end of the branch pipe 544 extends into the cleaning cabinet 51 and faces the guide plate 55, ensuring that dust and foreign matter directly enter the filtering system of the cleaning cabinet 51 through the branch pipe 544. The design of the branch pipe 544 ensures the directional flow of dust and avoids the retention and accumulation of dust in the pipeline 54. The reasonable design and connection of the branch pipe 544 and the main pipe 543 ensure the smooth transmission of dust from the processing room to the cleaning cabinet 51. The arrangement of the branch pipe 544 facing the guide plate 55 increases the stability of the airflow and avoids the backflow and blockage of dust during the transmission process.
