Description

Technical Field

[0001] This application relates to the field of chemical technology, and more specifically, to a solid crushing apparatus for chemical use. Background Technology

[0002] Chemistry is a natural science that studies the composition, structure, properties, transformation and application of matter at the molecular and atomic levels. In chemical experiments, it is often necessary to crush solid materials to facilitate subsequent chemical reactions or analysis. Specialized crushing equipment is usually used when crushing is required.

[0003] When using a solid compaction device to compact solid materials, it is necessary to put the materials into the device one by one when compacting multiple batches or different types of solid materials. This not only makes the operation cumbersome and reduces efficiency, but also makes the device prone to clogging during the compaction process, affecting the compaction effect. Therefore, when continuously conveying and compacting multiple batches or different solid materials, it is usually necessary to use multiple devices or implement quantitative compaction. However, this not only increases the difficulty and cost of operation, but also reduces work efficiency and compaction effect.

[0004] Therefore, how to improve the working efficiency of chemical solid crushing equipment has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to disclose a chemical solid compaction device to improve the working efficiency of the chemical solid compaction device.

[0006] A solid crushing device for chemical use includes a conveying mechanism, a pre-crushing mechanism, and a crushing mechanism;

[0007] The conveying mechanism includes a conveying pipe, a conveying component, and a first driving device. The conveying pipe is provided with an inlet and an outlet.

[0008] The feed end of the pre-crushing mechanism is connected to the discharge port and is used to perform preliminary crushing on the material discharged from the discharge port;

[0009] The feed end of the crushing mechanism is connected to the discharge end of the pre-crushing mechanism, and is used to crush the material crushed by the pre-crushing mechanism to obtain the finished material.

[0010] In one possible implementation, the chemical solids compaction device further includes:

[0011] A cleaning fan is provided at one end of the conveying mechanism and is used to blow air into the conveying pipe.

[0014] In one possible implementation, the conveying mechanism further includes a sealing cover for closing the feed inlet.

[0015] In one possible implementation, the cleaning fan is provided with a mounting flange, the mounting flange forming a flange cavity, and one end of the air inlet pipe is fixed to the mounting flange and communicates with the flange cavity.

[0016] In one possible implementation, the cleaning fan and the first drive device are respectively located at both ends of the delivery pipe.

[0017] In one possible implementation, the air intake duct assembly further includes a filter disposed at the end of the air intake duct that communicates with the atmosphere, for purifying the intake air.

[0018] In one possible implementation, there are two feed inlets, and the discharge outlet is located between the two feed inlets. The conveying member is provided with a first spiral blade and a second spiral blade with opposite rotation directions. One of the discharge outlets corresponds to the first spiral blade, and the other discharge outlet corresponds to the second spiral blade. The discharge outlet is located close to the first spiral blade and the second spiral blade.

[0019] In one possible implementation, the pre-crushing mechanism includes:

[0023] In one possible implementation, the conveying mechanism further includes an observation port and a cover plate, the observation port being disposed on the conveying pipe and the cover plate being used to close the observation port.

[0024] In the operation of the chemical solid crushing apparatus disclosed in this application, the material to be crushed is fed into the inlet. The first drive device is activated, driving the conveyor to rotate. Because the conveyor is equipped with spiral conveying blades, the rotating blades propel the material forward within the closed conveying pipe and discharge it from the outlet.

[0037] The purpose of this application is to disclose a chemical solid compaction device to improve the working efficiency of the chemical solid compaction device.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] See Figure 1 and Figure 2 The chemical solid crushing apparatus disclosed in this application includes a conveying mechanism 200, a pre-crushing mechanism 300, and a crushing mechanism 100.

[0040] The conveying mechanism 200 includes a conveying pipe 210, a conveying component 220, and a first driving device 260. The conveying pipe 210 can be designed as a cylinder, made of rolled and welded steel pipe or steel plate. The conveying pipe 210 is provided with an inlet 212 and an outlet 211. The inlet 212 can be a section of pipe connected to the upper surface of the conveying pipe 210, used to receive the material to be crushed. The outlet 211 can be located on the lower surface of the conveying pipe 210, used to discharge the material to be crushed. The conveying component 220 is disposed inside the conveying pipe 210, and its cylindrical side is provided with spiral conveying blades. The spiral conveying blades are made of stamped or wound steel plate, and are tightly wrapped and fixed to the conveying component 220 by welding or bolt clamping, thereby forming a continuous spiral structure.

[0041] The first drive device 260 is used to drive the conveyor 220 to rotate, so as to push the material entering through the feed port 212 towards the discharge port 211. Specifically, the first drive device 260 may consist of a motor and a reducer. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to the shaft end of the conveyor 220. The reducer is used to increase the torque, so that the conveyor 220 has greater force when rotating, thereby better completing the conveying of solid materials.

[0042] The pre-crushing mechanism 300 is used to initially crush the material discharged from the outlet 211, breaking the solid material into smaller particles to facilitate subsequent compaction and improve compaction efficiency. Its inlet end is sealed to the outlet 211, which ensures that the material does not leak during the transfer from the conveying pipe 210 to the pre-crushing mechanism 300, effectively suppressing dust.

[0043] The crushing mechanism 100 is a device for crushing solid materials. Its feed end is connected to the discharge end of the pre-crushing mechanism 300. It is used to crush the material after it has been crushed by the pre-crushing mechanism 300 to obtain the finished material.

[0044] During operation, the material to be crushed is fed into the feed inlet 212. The first drive device 260 is activated, driving the conveyor 220 to rotate. Because the conveyor 220 is equipped with spiral conveying blades, the rotating blades propel the material forward within the enclosed conveying pipe 210 and discharge it from the outlet 211. The material then enters the pre-crushing mechanism 300 through the connection port. At this time, the pre-crushing mechanism 300 crushes the incoming material. The crushed fine material is discharged from the outlet end of the pre-crushing mechanism 300 and falls into the crushing mechanism 100 below. The crushing mechanism 100 crushes the material, ultimately yielding the finished product.

[0045] Compared to related technologies, the chemical solid crushing device disclosed in this application, through the setting of a conveying mechanism and a pre-crushing mechanism, realizes rapid conveying and preliminary crushing of solid materials, which not only improves work efficiency but also ensures the accuracy and quality of crushing. In use, the operator only needs to put the solid material into the device through the feed pipe, and the device can automatically complete the conveying and preliminary crushing process, and finally send it into the crushing device for crushing. The whole operation process is simple and quick, without much manual intervention, which greatly reduces labor intensity.

[0046] To avoid cross-contamination between batches, when the same compaction device is used for different batches of materials, the residue from the previous batch must be cleaned after each batch is completed. This prevents potential catalyst poisoning, product deterioration, or safety hazards. For ease of cleaning, in one specific embodiment, the chemical solid compaction device may also include a cleaning fan 400 and an air inlet duct assembly 500. The cleaning fan 400, which can be a centrifugal fan, is located at one end of the conveying mechanism 200 and is used to blow air into the conveying pipe 210. After the device is used, the cleaning fan 400 is activated. The airflow generated by the cleaning fan 400 blows out any remaining solid material inside the conveying pipe 210, facilitating cleaning by personnel. This helps prevent solid material residue from causing blockages or affecting subsequent use, improving the cleanliness and efficiency of the device.

[0047] The air inlet duct assembly 500 includes an air inlet pipe 510, one end of which is connected to the delivery pipe 210 and the other end of which is connected to the atmosphere. The air inlet pipe 510 can be made of galvanized steel, stainless steel, or pressure-resistant PVC (polyvinyl chloride) pipe, and designers in the art can choose according to the airflow pressure and environment. The inner wall of the air inlet pipe 510 is smooth to reduce airflow resistance. If the cleaning fan 400 is started directly under load, it will generate a large inrush current on the motor, affecting its lifespan; while when the fan is stopped, the negative pressure inside the air inlet pipe 510 may cause dust to be drawn back, contaminating the air inlet pipe 510. To solve the above problems, a switching valve 520 is provided on the air inlet pipe 510. The switching valve 520 can be an electric valve or a pneumatic valve, used to control the opening and closing of the air inlet pipe 510. When the cleaning fan 400 starts, the switch valve 520 opens slowly to prevent the cleaning fan 400 from starting under load and reduce the impact of the starting current; when the cleaning fan 400 stops, the switch valve 520 closes quickly to prevent residual dust in the delivery pipe 210 from being sucked back into the air inlet pipe 510 at the moment of shutdown, thus protecting the fan impeller.

[0048] To collect residual material blown out of the conveying pipe 210, in one embodiment, the chemical solids compaction device may also include a dust collection bag. When the cleaning blower 400 is in cleaning mode, the collection port of the dust collection bag is connected to the feed inlet 212. The dust collection bag has high air permeability and filtration properties to allow airflow while trapping residual material. Specifically, the dust collection bag can be made of woven or non-woven fabric, and all seams of the bag body are sealed using a high-strength, leak-proof process. The dust collection bag can be designed as a cuboid or cylinder, with a pleated or accordion-shaped bottom to maximize the filtration area and reduce airflow resistance. The collection port may be equipped with a metal flange ring and secured using snap-fit, threaded connections, or fasteners to ensure a tight fit with the feed inlet 212 and prevent leakage. This design collects the material blown up by the cleaning blower 400, preventing dust from spreading into the air and causing pollution.

[0049] In another specific embodiment, a sealing cover 250 may be provided at the feed inlet 212. The sealing cover 250 may be connected to the feed inlet 212 by means of snap-fit, threaded connection, etc., to ensure airtightness. When the cleaning fan 400 is started to clean the residual solid material inside the conveying pipe 210, the sealing cover 250 is used to close the feed inlet 212, so that the residual solid material cannot be blown out from the feed inlet 212, but is blown out from the discharge outlet 211, and thus enters the pre-crushing mechanism 300 for pre-crushing. This design is beneficial for further utilizing the residual solid material, reducing the loss of material in the chemical solid crushing device, and improving the finished product yield. When the device is not in use, the sealing cover 250 can seal the feed pipe 23 to prevent dust or impurities from entering the inside of the device, ensuring the cleanliness of the inside of the device.

[0050] In another specific embodiment, the cleaning fan 400 may be provided with a mounting flange 410, which forms a flange cavity. One end of the air inlet pipe 510 is fixed to one side of the mounting flange 410 and communicates with the flange cavity. The other side of the mounting flange 410 is provided with a threaded hole, and the outer wall of the conveying pipe 210 is provided with a mounting hole. A fixing bolt passes through this mounting hole and is threadedly connected to the mounting flange 410. It can be understood that by setting up the mounting flange 410, the cleaning fan 400 can be securely installed on the conveying pipe 210, preventing the cleaning fan 400 from shaking or falling off during operation, thereby improving the stability and safety of the entire device. During on-site installation, workers only need to use bolts to fix the mounting flange 410 to the equipment base. This eliminates the tedious steps of separately aligning and fixing the cleaning fan 400 and the air inlet pipe 510, significantly shortening installation time and reducing installation difficulty. When major repairs to the equipment or the cleaning fan 400 itself are required, the entire module can be completely removed simply by loosening the bolts, making it highly maintainable.

[0051] In one specific embodiment, the cleaning fan 400 and the first drive unit 260 can be respectively disposed at both ends of the conveying pipe 210. This design allows airflow to flow from the cleaning fan 400 end to the first drive unit 260 end, and the airflow can sweep away light, dusty materials adhering to the surface of the spiral blades and the inner wall of the casing, preventing material accumulation and agglomeration. Placing the two larger components at opposite ends helps to balance the stress state of the device to a certain extent, making the center of gravity more balanced, thereby improving the stability of the entire device. At the same time, it also makes the structure more compact, facilitating its arrangement in limited installation space.

[0052] Because dust particles in the air impact the fan impeller with the high-speed airflow, it causes wear and reduces the lifespan of the cleaning fan 400. Simultaneously, this dust is also blown into the delivery pipe 210, causing contamination and failing to meet the requirements of high-cleanliness environments. To address these issues, the air inlet duct assembly 500 may also include a filter 530. The filter 530 is located at the end of the air inlet duct 510 that connects to the atmosphere. It removes dust, moisture, oil mist, and other impurities from the air, protecting the impeller of the cleaning fan 400 from wear and ensuring that the airflow blowing towards the delivery pipe 210 is clean. In one embodiment, the filter 530 may employ a two-stage filtration scheme, such as using medium-efficiency filter cotton or metal mesh filter elements as the primary filter element to filter large particles of dust, insects, and willow catkins; and using bag or plate filter elements as the fine filter element to filter fine dust particles. This design, by incorporating the filter 530, effectively removes various impurities from the ambient air, ensuring the cleanliness of the airflow blowing towards the delivery pipe 210, preventing contamination, and meeting high-standard process requirements. Furthermore, the clean air flowing through the cleaning fan 400 prevents dust particles from eroding the fan impeller, greatly extending the fan's service life and maintenance cycle.

[0053] To enable the chemical solids compaction device to simultaneously process materials from two different sources, in one specific embodiment, there may be two feed inlets 212, located on the upper surface of the conveying pipe 210. There is one discharge outlet 211, located between the two feed inlets 212, on the lower surface of the conveying pipe 210. The conveying member 220 is provided with a first helical blade and a second helical blade rotating in opposite directions. In the embodiments disclosed in this application, the first and second helical blades are located at opposite ends of the conveying member 220, with the midpoint of the conveying member 220 as the boundary. One discharge outlet 211 corresponds to the first helical blade, and the other discharge outlet 211 corresponds to the second helical blade, with the discharge outlet 211 positioned close to the first and second helical blades.

[0054] When the conveyor 220 rotates under the drive of the first drive device 260, the materials fed into the two inlets 212 are conveyed towards the center by the first and second helical blades, as the first and second helical blades rotate in opposite directions. The two material streams eventually converge in the middle region of the conveying pipe 210 and are discharged through the single outlet 211 located on the lower surface of this region. This design enables a single device to simultaneously process two feed streams and converge them into one discharge point. The device has a compact structure, greatly saving equipment floor space and initial investment costs. It simplifies the complex multi-feed convergence process into a single mechanical conveying process, resulting in high system reliability and easy operation and maintenance. When different materials are fed from both inlets, the device provides a certain degree of pre-mixing effect while fulfilling its conveying function.

[0055] In one specific embodiment, the pre-crushing mechanism 300 may include a housing 310, a first crushing wheel 330, a second crushing wheel 320, and a second drive device. One end of the housing 310 is connected to the discharge port 211, and the other end is connected to the crushing mechanism 100. The interior of the housing 310 forms a crushing chamber. The first crushing wheel 330 and the second crushing wheel 320 are rotatably mounted on the side walls of the housing 310, and the axes of the first crushing wheel 330 and the second crushing wheel 320 are parallel. The first crushing wheel 330 and the second crushing wheel 320 are provided with crushing teeth, which are arranged in an alternating pattern to enhance the shearing and tearing effect.

[0056] The second drive unit is used to drive the first crushing wheel 330 and the second crushing wheel 320 to rotate in opposite directions. Specifically, the second drive unit includes a crushing motor 360, a first gear 340, and a second gear 350. The crushing motor 360 is disposed in the housing 310, and its output end is connected to the first crushing wheel 330. The first gear 340 is connected to the shaft end of the first crushing wheel 330, and the second gear 350 is connected to the shaft end of the second crushing wheel 320. The first gear 340 and the second gear 350 mesh. This achieves synchronous driving of the two crushing wheels to rotate in opposite directions by a single motor.

[0057] After entering the pre-crushing mechanism 300, the material falls between the first crushing wheel 330 and the second crushing wheel 320, which rotate in opposite directions. Under the action of friction, the material is carried into the meshing zone of the two wheels. In this zone, the material is crushed by the squeezing, splitting, and strong shearing action of the crushing teeth. The crushed material is discharged through the discharge end of the pre-crushing mechanism 300 below the two wheels, completing the preliminary crushing operation.

[0058] In one specific embodiment, the conveying mechanism 200 may further include an observation port 240 and a cover plate 230. The observation port 240 is disposed in the conveying pipe 210, and the cover plate 230 is used to close the observation port 240. Through the observation port 240, operators can directly observe the conveying of solid materials inside the conveying pipe 210 and the operating status of the conveying component 220, thereby promptly identifying and resolving potential problems during the conveying process, ensuring the stability and reliability of the conveying process. Simultaneously, the observation port 240 also facilitates cleaning and maintenance of the inside of the conveying pipe 210, extending the service life of the device. With the cover plate 230, the observation port 240 can be closed when not being observed or cleaned, preventing dust or impurities from entering the inside of the conveying pipe 210 through the observation port 240.

[0059] In one specific embodiment, the compaction mechanism 100 may be equipped with a support frame 130, which is made of welded or bolted steel sections, such as angle steel or channel steel, to provide stable support for the conveying mechanism 200. The height and structure of the support frame 130 can be designed and adjusted according to actual production needs.

[0060] To improve the stability of the chemical solid compaction device, an anti-slip pad 110 is provided at the bottom of the compaction mechanism 100. The anti-slip pad 110 increases the friction between the compaction mechanism 100 and the ground or supporting surface, thereby improving the stability of the compaction mechanism 100 during operation, preventing it from sliding or tilting due to uneven force or improper operation, and ensuring the safety of the device.

[0061] To improve the operational safety of the chemical solid compaction device, an audible and visual alarm 120 is installed on the compaction mechanism 100. When the compaction mechanism 100 malfunctions or experiences an abnormality, the audible and visual alarm 120 will promptly issue an alarm signal to alert the staff, enabling timely detection and resolution of the fault, thus ensuring the safety and reliability of the device.
