Description

Technical Field

[0001] This invention relates to the field of ventilation and dust removal technology, and in particular to a ventilation and dust removal device for the crushing workshop of a lithium iron phosphate recycling production line. Background Technology

[0002] The ventilation and dust removal system in the crushing workshop of the lithium iron phosphate recycling production line relies on a combination of sealed air collection hoods, duct negative pressure suction, bag filter dust collection, and activated carbon adsorption. It utilizes a variable frequency energy-saving fan as the core of the negative pressure power, and incorporates optimized energy-saving design of the workshop building to collect ultrafine lithium salt dust generated during material crushing and screening. The variable frequency energy-saving fan can dynamically adjust its speed and air pressure according to the start / stop of the crushing equipment and the amount of dust generated, eliminating the energy waste caused by the continuous full-load operation of traditional fixed frequency fans. At the building level, the system optimizes the workshop's air intake and exhaust layout and uses an airtight enclosure structure to reduce uncontrolled dust generation. Airflow disturbance and heat loss are mitigated by graded filtration to remove coarse and fine dust and adsorb trace amounts of harmful volatile substances. Combined with workshop replacement ventilation to balance internal air pressure, this system not only suppresses dust overflow, improves the working environment, and protects occupational health, but also recovers high-value lithium iron phosphate powder to reduce raw material loss. At the same time, it stabilizes workshop cleanliness and avoids the risk of dust accumulation and explosion. The entire system relies on the synergistic energy-saving control of the fan frequency converter and the building's airflow energy-saving structure to reduce energy consumption. Under the premise of meeting dust removal safety standards, it significantly reduces long-term power consumption and is suitable for the continuous, high-dust, and long-term operation conditions of the crushing section.

[0003] The existing lithium iron phosphate recycling and crushing workshop uses conventional industrial air conditioning units to build the ventilation and dust removal structure. Under the high dust conditions in the workshop, ultrafine graphite electrode dust can easily and quickly adhere to and clog the air conditioning intake filter, causing the airflow resistance in the duct to continuously increase. This forces the air conditioning fan and dust removal fan to operate under overload for a long time, resulting in a significant increase in energy consumption. At the same time, a large amount of ultrafine conductive graphite dust penetrates the filter and enters the unit. The continuous accumulation and friction of dust can easily generate static electricity and discharge sparks. The intrusion of conductive dust into electrical components can also cause short circuits, equipment failures, and affect the service life of the air conditioning unit.

[0004] In summary, the existing technology lacks a technique for pre-treating graphite electrode dust in air conditioning units. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing a ventilation and dust removal device for the crushing workshop of a lithium iron phosphate recycling production line.

[0009] Preferably, the processing component includes a flow guide seat located on the outer side of the bottom end of the air conditioner intake cylinder.

The other end of the first flow guide pipe extends into the air conditioner intake cylinder and is rotatably connected to an annular spray pipe. The other end of the second flow guide pipe passes through the outer wall of the air conditioner intake cylinder and extends directly below the plastic sintering plate. One end of the annular spray pipe is fixedly connected to one end of the disintegration frame.

[0010] Preferably, a piston rod is slidably fitted through the inner wall of the water pump seat. A connecting rod is rotatably connected to the outer end of the piston rod, and a rotating rod is rotatably connected to the other end of the connecting rod. The other end of the rotating rod is rotatably connected to the outer wall of the water pump seat via a pin. A driven wheel is fixedly connected to the top end of the pin, and the driven wheel is meshed with the driving wheel for transmission. An inlet pipe and an outlet pipe are respectively fixedly connected through the water pump seat. The other end of the inlet pipe is fixedly connected through the inner wall of the condensate tank, and the other end of the outlet pipe is fixedly connected through the inner wall of the bottom end of the guide seat.

[0011] Preferably, the flushing assembly includes an electric actuator, one end of which is fixedly connected to the bottom end of the air conditioner intake cylinder, and the output end of which is fixedly connected to the outer end of the guide block. A telescopic rod is rotatably connected through the output end of the electric actuator, and one end of the telescopic rod is rotatably connected through the outer wall of the conical settling hopper. Universal joints are fixedly connected to both ends of the telescopic rod. The other end of the universal joint near the electric actuator is rotatably connected to the output end of the electric actuator and fixedly connected to a transmission wheel. The transmission wheel is movably meshed with the drive wheel for transmission. One end of another universal joint extends through the outer wall of the air conditioner intake cylinder to the interior and is rotatably connected through the inner wall of the second guide pipe output end.

[0012] Preferably, the bottom end of the conical settling bucket is fixedly connected to a graphite slurry cylinder, the bottom opening of the graphite slurry cylinder is threaded with a sealing cap, the inner wall of the conical settling bucket is fixedly connected to an electric actuator, the output end of the electric actuator is fixedly connected to an isolation plug, and the isolation plug is adapted to the inner wall of the graphite slurry cylinder.

[0013] Preferably, a valve is fixedly connected through the inner wall of the conical settling hopper near the bottom end. The output end of the valve is connected to the inner wall of the condensate tank. An opening and closing guide groove is provided on the outer wall of the valve stem. A transmission rod is fixedly connected to one side of the top of the isolation plug. The other end of the transmission rod is slidably engaged with the inner wall of the opening and closing guide groove.

[0014] Preferably, the side wall of the condensate tank is fixedly connected with an overflow pipe joint and a water filling pipe joint.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By installing a treatment component inside the air intake cylinder of the air conditioning unit casing, and using a water pump to extract and atomize the condensate from the air conditioning unit itself, the ultrafine graphite dust in the intake airflow is agglomerated and flocculated. This not only prevents fine dust from penetrating the front-end filter structure, reducing the probability of air conditioning intake filter clogging, but also stabilizes the air conditioning ventilation intake volume and heat exchange efficiency, ensuring the air conditioning ventilation system's intake air control requirements. At the same time, the moist airflow can quickly dissipate the static electricity accumulation of dust, avoid electrostatic discharge sparks, reduce the risk of dust combustion and explosion, optimize the air conditioning unit's intake air purification capacity, and reduce the energy consumption of auxiliary air conditioning units by recycling condensate, thereby improving the air conditioning system's operational safety, dust removal and purification effect, and energy-saving control level, and meeting the requirements for stable temperature control and ventilation of air conditioning units under high dust conditions.

[0016] By using an air intake dispersion component installed inside the air intake cylinder, the concentrated influx of dust-laden airflow can be disturbed and dispersed. At the same time, the piston rod of the water pump seat reciprocates to automatically extract and supply condensate water, eliminating the need for an independent water pump power supply structure, reducing the load on the air conditioning electrical control system and the overall energy consumption of the unit, and meeting the energy-saving control design requirements of air conditioning units. Multiple sets of guide plates inside the cylinder extend the residence time of the dust-laden airflow, enhance the fusion and settling effect of water vapor and graphite dust, further reduce the amount of dust entering the air conditioner, reduce the degree of filter clogging, stabilize the air conditioning ventilation volume, and improve the air intake pretreatment effect and ventilation condition control stability of the air conditioner.

[0017] By setting up a flushing component to switch the condensate delivery pipeline, the unit's self-produced condensate is used to automatically flush the plastic sintered plate filter surface at the air inlet and outlet of the air inlet at regular intervals. This continuously clears the filter pores, maintains the air intake smoothness and heat exchange efficiency of the air conditioner for a long time, reduces the problem of high-load operation of the fan caused by frequent filter clogging, and extends the service life of the air conditioning equipment. The conical settling hopper is equipped with a graphite slurry cylinder and an isolation plug. Before the slurry is taken out and discharged, the isolation plug is used to separate the slurry from the upper clear water, preventing slurry impurities from flowing back and contaminating the condensate circulation pipeline, ensuring the cleanliness of the condensate supply, stabilizing the working conditions of the atomization humidification and flushing water supply system, and ensuring the long-term stable and controllable operation of the integrated air conditioning ventilation, temperature control, and dust removal system.

[0020] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] like Figures 1-8 The ventilation and dust removal device for the crushing workshop of a lithium iron phosphate recycling production line shown includes an air conditioning unit shell 1. An air conditioning inlet 2 for sucking up graphite electrode dust in the crushing workshop of the lithium iron phosphate recycling production line is fixedly connected to one side of the top of the air conditioning unit shell 1. An air intake dispersion component 3 for stirring and dispersing the dusty air is rotatably connected inside the air intake end of the air conditioning inlet 2. A treatment component 4 for wetting and agglomerating the graphite electrode dust in the air is fixedly connected to one side of the air intake dispersion component 3. A water pump seat 5 for sucking up condensate is fixedly connected to the bottom end of the air conditioning inlet 2. A flushing component 6 is fixedly connected to the bottom end of the air conditioning inlet 2. A conical settling hopper 7 for automatically settling the agglomerated graphite dust is fixedly connected through the bottom end of the air conditioning inlet 2. A condensate tank 8 for collecting the condensate generated by the air conditioning unit is installed and fixedly installed on the bottom side wall of the air conditioning unit shell 1.

[0022] By installing a processing component 4 inside the air intake sump 2 of the air conditioning unit casing 1, and using a water pump base 5 to extract and atomize the condensate from the air conditioning unit itself, the ultrafine graphite dust in the intake airflow is agglomerated and flocculated. This not only prevents fine dust from penetrating the front-end filter structure, reducing the probability of air conditioning intake filter blockage, but also stabilizes the air conditioning ventilation intake volume and heat exchange efficiency, ensuring the air conditioning ventilation system's intake air control requirements. At the same time, the moist airflow can quickly dissipate the static electricity accumulation of dust, avoid electrostatic discharge sparks, reduce the risk of dust combustion and explosion, optimize the air conditioning unit's intake air purification capacity, reduce the energy consumption of auxiliary air conditioning units by recycling condensate, and improve the air conditioning system's operational safety, dust removal and purification effect, and energy-saving control level, thus meeting the stable temperature control and ventilation requirements of the air conditioning unit under high dust conditions.

[0023] like Figure 3 As shown, a plastic plate 201 is fixedly connected to the inner wall of the air conditioner air inlet 2 near the end connected to the air conditioner unit casing 1, and multiple guide plates 202 are fixedly connected to the inner wall of the air conditioner air inlet 2 in an alternating inclined structure.

[0024] The sintered plastic plate 201 is a high-precision filter component with the characteristics of being moisture-resistant, wear-resistant, not easy to clog, and repeatedly washable. It can perform secondary interception and filtration of graphite dust after it has been moistened and agglomerated, ensuring the cleanliness of the exhaust gas. The multiple sets of guide plates 202 arranged in an alternating and inclined manner form a tortuous airflow channel, which forces the dust-laden airflow to flow back and forth, effectively prolonging the airflow residence time, improving the contact efficiency between water mist and dust, and at the same time, it can buffer and guide the agglomerated dust to settle, reducing the probability of secondary dust re-entrainment.

[0025] like Figure 4 As shown, the air intake dispersing assembly 3 includes a dispersing frame 301, which is rotatably connected to the inner wall of the air intake end of the air conditioning air intake cylinder 2. A worm gear 302 is fixedly connected to one end of the dispersing frame 301 located on the inner wall of the air conditioning air intake cylinder 2. A worm 303 is meshed and driven on one side of the worm gear 302. The bottom end of the worm 303 extends through the inner wall of the air conditioning air intake cylinder 2 to the outside and is fixedly connected to a motor 304. The motor 304 is fixedly connected to the air conditioning air intake cylinder 2. A drive wheel 305 is fixedly connected to one end of the worm 303 near the motor 304.

[0026] The dispersing frame 301 is connected to rings of different sizes, which can disperse dust airflows of different particle sizes and different degrees of agglomeration in layers and multiple stages, break up dust clumps, and make ultrafine graphite dust evenly dispersed in the airflow, greatly improving the subsequent atomization and humidification effect.

[0027] like Figure 5As shown, the processing component 4 includes a flow guide seat 401, which is located on the outer side of the bottom end of the air conditioner intake cylinder 2. A flow guide block 402 is slidably fitted through the upper inner wall of the flow guide seat 401. Two flow guide holes 403 are symmetrically opened through the flow guide block 402. A first flow guide pipe 404 and a second flow guide pipe 405 are fixedly connected through the top of the flow guide seat 401. The other end of the first flow guide pipe 404 extends into the air conditioner intake cylinder 2 and is rotatably connected to an annular spray pipe 406. The other end of the second flow guide pipe 405 passes through the outer wall of the air conditioner intake cylinder 2 and extends directly below the plastic sintering plate 201. One end of the annular spray pipe 406 is fixedly connected to one end of the disintegration frame 301.

[0028] The guide block 402 enables the switching and conduction of guide pipe 1 404 and guide pipe 2 405. Under normal conditions, guide pipe 1 404 is connected to deliver condensate to the annular spray pipe 406, which rotates synchronously with the disintegration frame 301 to achieve 360° rotating atomized water spray and humidify the dust-laden airflow. Under the flushing condition, guide pipe 2 405 is switched to connect, the atomization circuit is closed and the flushing circuit is opened, and the water source is switched to the sintered plastic plate 201 flushing structure to achieve free switching between dust removal and flushing modes.

[0029] like Figure 6 As shown, a piston rod 501 is slidably fitted through the inner wall of the water pump seat 5. A connecting rod 502 is rotatably connected to the outer end of the piston rod 501. A rotating rod 503 is rotatably connected to the other end of the connecting rod 502. The other end of the rotating rod 503 is rotatably connected to the outer wall of the water pump seat 5 via a pin. A driven wheel 504 is fixedly connected to the top of the pin. The driven wheel 504 is meshed with the driving wheel 305 for transmission. An inlet pipe and an outlet pipe are fixedly connected through the water pump seat 5. The other end of the inlet pipe is fixedly connected through the inner wall of the condensate tank 8. The other end of the outlet pipe is fixedly connected through the inner wall of the bottom end of the guide seat 401.

[0030] One-way valves are installed in the inlet and outlet pipes, and a filter element is installed in the inlet pipe to filter the condensate.

[0031] like Figure 7As shown, the flushing assembly 6 includes an electric actuator 601. One end of the electric actuator 601 is fixedly connected to the bottom end of the air conditioning intake 2, and the output end of the electric actuator 601 is fixedly connected to the outer end of the guide block 402. A telescopic rod 602 is rotatably connected through the output end of the electric actuator 601. One end of the telescopic rod 602 is rotatably connected through the outer wall of the conical settling hopper 7. Universal joints 603 are fixedly connected to both ends of the telescopic rod 602. The other end of the universal joint 603 near the electric actuator 601 is connected to the electric actuator 601. The output end of push rod 601 is rotatably and fixedly connected to a transmission wheel 604. The transmission wheel 604 is movably meshed with the drive wheel 305 for transmission. One end of another universal joint 603 extends through the outer wall of the air conditioner intake 2 and is rotatably connected to the inner wall of the output end of the guide pipe 405. The end of universal joint 603 located on the inner wall of the output end of the guide pipe 405 is fixedly connected to a flushing pipe 605. The water inlet end of the flushing pipe 605 is rotatably connected to the output end of the guide pipe 405.

[0032] The electric actuator 601 moves the guide block 402, switches the flow path, and drives the transmission wheel 604 to mesh with the drive wheel 305, thereby driving the flushing pipe 605 to rotate and flush.

[0033] like Figure 8 As shown, the bottom end of the conical settling bucket 7 is fixedly connected to the graphite mud cylinder 701. The bottom opening of the graphite mud cylinder 701 is threaded with a sealing cap. The inner wall of the conical settling bucket 7 is fixedly connected to an electric push rod 702. The output end of the electric push rod 702 is fixedly connected to an isolation plug 703. The isolation plug 703 is adapted to the inner wall of the graphite mud cylinder 701.

[0034] A valve 704 is fixedly connected through the inner wall of the conical settling hopper 7 near the bottom. The output end of the valve 704 is connected to the inner wall of the condensate tank 8. An opening and closing guide groove 705 is opened on the outer wall of the valve stem of the valve 704. A transmission rod 706 is fixedly connected to one side of the top of the isolation plug 703. The other end of the transmission rod 706 is slidably engaged with the inner wall of the opening and closing guide groove 705.

[0035] The lower end of the opening and closing guide groove 705 is arranged in a spiral structure, and the upper end is arranged in a straight structure, so that when the isolation plug 703 continues to move after being inserted into the graphite mud cylinder 701, it can drive the valve 704 to open through the transmission rod 706.

[0036] like Figure 2 As shown, overflow pipe joints and water filling pipe joints are fixedly connected through the side walls of the condensate tank 8.

[0037] The overflow pipe connector allows excess water in the condensate tank 8 to be drained, while the water inlet pipe connector allows water to be added from an external water source when the water in the condensate tank 8 is insufficient.

[0038] Working principle: During normal dust removal operations, the condensate generated by the air conditioning unit is collected and stored in the condensate tank 8, providing a stable circulating water source for dust removal atomization. Then, the air conditioning main control motor 304 starts and drives the worm gear 303 to rotate. Through the meshing and deceleration of the worm wheel 302, the air intake end dispersing frame 301 rotates at a low speed. Relying on the staggered ring structure, the high-concentration graphite dust-containing airflow drawn into the air conditioning intake cylinder 2 is fully dispersed, so that the ultrafine dust is evenly dispersed in the air.

[0039] Then, during the rotation of the worm gear 303, the driving wheel 305 is driven to rotate synchronously. The driving wheel 305 meshes with and drives the driven wheel 504 to rotate, which in turn drives the rotating rod 503 and the connecting rod 502 to pull the piston rod 501 to slide back and forth inside the water pumping seat 5. With the one-way conduction of the inlet and outlet water pipe check valves, the condensate in the condensate tank 8 is continuously drawn into the guide seat 401. Under normal conditions, the guide block 402 connects the water passage of the guide pipe 404, and the condensate is delivered to the annular spray pipe 406, which rotates synchronously with the atomizing frame 301 and is sprayed out to form a fine water mist all over the area.

[0040] Then, the atomized water mist comes into full contact with the dispersed dust-laden airflow, causing the suspended ultrafine graphite dust to quickly absorb water vapor, increase its weight, and clump together. At the same time, it continuously removes static electricity from the dust, completely eliminating the risk of static explosion. The dust-laden airflow is blocked and deflected inside the air conditioning intake duct 2 by the staggered guide plate 202, which greatly prolongs the residence time inside the duct, ensuring that the dust is fully and thoroughly wetted and clumped. The large dust particles after clumping fall along the duct wall into the conical settling hopper 7 under the action of gravity, and finally converge into the graphite slurry duct 701 to form graphite slurry, completing the dust settling and purification. The remaining clean airflow is discharged after secondary fine filtration by the sintered plate 201, ensuring the cleanliness and ventilation of the workshop.

[0041] When the surface of the sintered plastic plate 201 is clogged with ash and the filtration resistance increases, the automatic flushing mode is activated. The air conditioning main control electric push rod 601 drives the guide block 402 to slide and switch the water circuit, closing the atomization circuit of the guide pipe 404 and opening the flushing circuit of the guide pipe 405. At the same time, the electric push rod 601 drives the transmission wheel 604 to move and mesh with the drive wheel 305. The power is transmitted through the universal joint 603 and the telescopic rod 602, which drives the flushing pipe 605 to rotate. High-pressure water is sprayed out from the flushing pipe 605 to perform a 360° all-round rotation flushing of the filter surface of the sintered plastic plate 201, thoroughly removing the ash accumulation in the pores and restoring the filtration permeability.

[0042] When it is necessary to clean the bottom graphite slurry cylinder 701, the air conditioning main control starts the electric actuator 702 to push the isolation plug 703 downward. It first inserts into the graphite slurry cylinder 701 to achieve physical isolation between the slurry and the upper layer of clean water, preventing the slurry from overflowing and flowing back. As the isolation plug 703 continues to move downward, the top transmission rod 706 slides along the opening and closing guide groove 705 on the outside of the valve 704. Through the lower spiral structure guide groove, it drives the valve rod to rotate, automatically opening the valve 704, allowing the upper layer of clean water inside the conical settling hopper 7 to flow back to the condensate tank 8, completing the clean water recovery. After the water return is completed, the bottom sealing cover of the graphite slurry cylinder 701 can be unscrewed to clean the graphite slurry. The entire process eliminates circulating water pollution and ensures that the atomizing water path is clean and unblocked for a long time.
