Description

Technical Field

[0001] This utility model relates to the field of chemical manufacturing technology, and in particular to a chemical raw material crusher. Background Technology

[0002] Chemical raw materials are the basic substances used to produce various chemical products through chemical processing. They are widely used in industry, agriculture, medicine, energy and other fields. Their sources are diverse, mainly including fossil resources such as petroleum, coal and natural gas, as well as natural raw materials such as salt, ore and biomass. With the development of green chemistry, the development of non-toxic and harmless raw materials and renewable raw materials has become a trend, aiming to reduce environmental pollution and promote the transformation of the chemical industry towards low-carbon and sustainable development.

[0003] In the prior art, chemical raw materials need to be crushed before use. The crushing process generates a lot of dust, which affects the surrounding environment and the respiratory health of operators. Traditional dust collection devices use high-power fans in conjunction with filters to absorb dust. The fans require a lot of energy, and the large airflow disturbance can easily cause dust to be stirred up again, which is not conducive to achieving the ideal dust collection effect. Therefore, in order to solve the above problems, this utility model proposes a chemical raw material crusher. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a chemical raw material crusher that uses a current valve to create an electrostatic field on the electrode plate to adsorb dust. Compared with traditional dust collection devices, this effectively reduces dust collection energy consumption, requires a lower fan speed to avoid dust being stirred up again due to airflow disturbance, and the electrostatic field adsorption can efficiently capture fine dust and dust particles, which is beneficial to improving the dust collection effect of the dust collection device.

[0005] This utility model provides the following technical solution: a chemical raw material crusher, including a shell, an inlet at the upper part of the inner cavity of the shell, a dust collection chamber fixedly sleeved on the left side of the shell, a fan fixedly installed on the left side of the dust collection chamber, a DC power supply fixedly installed on the upper part of the dust collection chamber, a current valve fixedly installed on the left side of the DC power supply, electrode plates uniformly fixedly installed on the top of the inner cavity of the dust collection chamber, a vibrating motor provided on the electrode plates, the electrode plates and the current valve connected by a circuit, a valve fixedly installed at the bottom of the dust collection chamber, a dust discharge pipe fixedly installed at the bottom of the valve, a dust collection box fixedly installed at the bottom of the dust discharge pipe, and a cover plate movably connected to the front of the dust collection box via a shaft. By forming an electrostatic field on the electrode plates to adsorb dust, the dust collection energy consumption is effectively reduced. The fan speed is relatively low to avoid airflow disturbance causing secondary dust re-entrainment. Electrostatic adsorption can efficiently capture fine dust and dust particles, improving the dust collection effect of the dust collection device.

[0006] Preferably, an exhaust pipe is fixedly installed at the bottom of the fan, and the right end of the exhaust pipe is fixedly connected to the left side of the housing. The upper and lower parts of the right end of the exhaust pipe are respectively provided with exhaust ports. A piston is movably connected in the inner cavity of the right end of the exhaust pipe. A push rod is movably connected to the right side of the piston through a shaft. When the fan draws in air, it discharges air into the exhaust pipe. The air pressure in the exhaust pipe increases, pushing the piston to move to the right. When the piston moves to the rightmost end of the exhaust pipe, the airflow is discharged through the exhaust port, thereby reducing the air pressure.

[0007] Preferably, a movable frame is movably connected within the inner cavity of the housing. The left side of the movable frame is movably connected to the right end of the push rod via a shaft. A filter screen is fixedly installed in the middle of the movable frame. A discharge port is provided on the right side of the inner cavity of the housing. A groove is provided at the bottom of the discharge port. Springs are uniformly fixedly installed on the right side of the inner cavity of the groove. The left end of the spring is fixedly connected to the movable frame. The piston pushes the movable frame through the push rod. The movable frame compresses the spring to the right, generating elastic potential energy. After the air pressure decreases, the movable frame returns to its original position under the action of the spring's elastic potential energy. This reciprocating motion realizes the left and right movement of the filter screen, thus screening the pulverized chemical raw materials.

[0008] Preferably, a support plate is fixedly installed on the right side of the housing, and a motor is fixedly installed on the upper part of the support plate. The output shaft of the motor is movably connected to the inner cavity of the housing. A gear one is fixedly connected to the output shaft of the motor. A gear two is meshed on the front extension of the gear one. A rotating shaft is fixedly connected to the left side of the gear two. The rotating shaft is movably connected to the inner cavity of the housing. When the motor is turned on, the gear one rotates. The meshing of the gear one and the gear two drives the rotating shaft to rotate, so that the front and rear crushing rollers rotate in opposite directions.

[0009] Preferably, a crushing roller is fixedly sleeved on the motor output shaft and the rotating shaft respectively. The crushing roller is located directly above the filter screen. Crushing rings are uniformly fixedly sleeved on the crushing roller. There are five crushing rings. Crushing claws are uniformly arranged on the outer edge of the crushing rings. There are eight crushing claws. The front and rear crushing rollers rotate in opposite directions under the drive mechanism. When the crushing rollers rotate, they drive the crushing claws to crush the chemical raw materials.

[0010] Preferably, the crushing ring includes a ring body, and the outer edge of the ring body is uniformly provided with a second groove. The inner cavity of the second groove is provided with a sliding groove on the left and right sides respectively. The second groove is provided with a threaded hole on the left and right sides and in front and behind the sliding groove. The number of the first threaded holes is four. By setting the sliding groove to fit with the rib, the friction between the crushing ring and the crushing claw is increased, making the connection between the two mechanisms more stable and reliable, and preventing detachment.

[0011] Preferably, the crushing claw includes a claw body, on which a fixing block is fixedly connected. The fixing block fits into a second groove. Ribs are fixedly installed on the left and right sides of the fixing block, and the ribs fit into a sliding groove. The fixing block has two threaded holes, and the left and right sides correspond to the first threaded hole, respectively. The fixing block can be removed from the first and second threaded holes by rotating the bolt. At this time, the fixing block can be removed from the second groove, thereby enabling quick replacement of the claw body with significant wear.

[0012] Preferably, the front and rear parts of the housing are respectively connected to the inspection plate by a shaft. The bottom of the inner cavity of the housing is provided with a discharge port 2. Support rods are evenly fixedly installed around the bottom of the housing and around the discharge port 2. The number of support rods is four. When maintaining the device, the inspection plate can be opened to maintain the crushing mechanism. It is not necessary to disassemble and replace the entire crushing mechanism during maintenance, which reduces maintenance costs and time, and helps to improve the maintenance efficiency of the device.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Dust is drawn into the ventilation duct by a fan. The current valve is opened to create an electrostatic field on the electrode plate, which adsorbs the drawn-in dust. Compared with traditional dust collection devices that require a fan to maintain high-speed airflow, electrostatic adsorption can achieve collection even at low wind speeds, reducing the energy consumption required for dust adsorption and preventing the adsorbed dust from being stirred up again due to airflow disturbance. Electrostatic adsorption can efficiently capture micron-sized ultrafine dust and even nano-sized particles, which helps to improve the dust collection effect of the dust collection device, avoids chemical raw material dust from polluting the surrounding environment of the crushing device, and prevents harm to the respiratory health of operators.

[0015] 2. While the blower draws in air, it also discharges air into the exhaust pipe. The increased air pressure in the exhaust pipe pushes the piston to the right, which in turn pushes the moving frame through the push rod. The moving frame compresses the spring to the right, generating elastic potential energy. When the piston reaches the rightmost end of the exhaust pipe, the airflow is discharged through the exhaust port, thus reducing the air pressure. The moving frame returns to its original position under the action of the spring's elastic potential energy. This reciprocating motion moves the filter screen left and right to screen the pulverized chemical raw materials, thereby improving the device's material screening efficiency and preventing excessive material accumulation on the filter screen, which could cause blockage.

[0016] 3. When maintaining the device, the inspection plate can be opened to maintain the crushing mechanism. The bolts can be turned to remove it from threaded hole one and threaded hole two. At this time, the fixing block can be removed from groove two, so that the claw body with large wear can be replaced. The above operation is reversed during installation. This avoids the need to disassemble the entire crushing mechanism for replacement during maintenance, reduces maintenance costs and time, and helps to improve the maintenance efficiency of the device.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-8A chemical raw material pulverizer includes a housing 1, with an inlet 2 at the upper part of the inner cavity of the housing 1. A dust collection chamber 3 is fixedly sleeved on the left side of the housing 1, and a fan 4 is fixedly installed on the left side of the dust collection chamber 3. A DC power supply 5 is fixedly installed on the upper part of the dust collection chamber 3, and a current valve 6 is fixedly installed on the left side of the DC power supply 5. Electrode plates 7 are evenly fixedly installed on the top of the inner cavity of the dust collection chamber 3, and a vibrating motor is installed on the electrode plates 7. The electrode plates 7 and the current valve 6 are connected by a circuit. A valve 8 is fixedly installed at the bottom of the dust collection chamber 3, and a dust discharge pipe 9 is fixedly installed at the bottom of the valve 8. A dust collection box 10 is fixedly installed at the bottom of the dust discharge pipe 9. A cover plate 11 is movably connected to the front of the dust collection box 10 via a shaft. The fan 4 draws dust generated from pulverizing chemical raw materials in the inner cavity of the housing 1 into the dust collection chamber 3. The current valve 6 is opened, causing the DC power supply 5 to release DC current to the electrode plates 7. Electricity creates an electrostatic field on electrode plate 7, which adsorbs the inhaled dust. During cleaning and maintenance, opening valve 8 and closing current valve 6 eliminates the electrostatic field on electrode plate 7 and activates the vibrating motor on electrode plate 7, causing the dust on electrode plate 7 to fall off. The dust falls along the dust discharge pipe 9 into the inner cavity of dust collection box 10. Opening cover 11 allows for dust removal. Compared to traditional dust collection devices that require a fan 4 to maintain high-speed airflow, electrostatic adsorption can achieve dust collection even at low wind speeds, reducing the energy consumption required for dust adsorption and preventing the adsorbed dust from being stirred up again due to airflow disturbance. Electrostatic adsorption can efficiently capture micron-sized ultrafine dust and even nano-sized particles, which helps improve the dust collection effect of the dust collection device, avoids chemical raw material dust from polluting the environment around the crushing device, and prevents harm to the respiratory health of operators.

[0028] A ventilation pipe 12 is fixedly installed at the bottom of the blower 4. The right end of the ventilation pipe 12 is fixedly connected to the left side of the housing 1. Exhaust ports 13 are respectively opened at the upper and lower parts of the right end of the ventilation pipe 12. A piston 14 is movably connected to the inner cavity of the right end of the ventilation pipe 12. A push rod 15 is movably connected to the right side of the piston 14 via a shaft. A movable frame 16 is movably connected to the inner cavity of the housing 1. The left side of the movable frame 16 is movably connected to the right end of the push rod 15 via a shaft. A filter screen 17 is fixedly installed in the middle of the movable frame 16. A discharge port 18 is opened on the right side of the inner cavity of the housing 1. A groove 19 is opened at the bottom of the discharge port 18. Springs 20 are evenly fixedly installed on the right side of the inner cavity of the groove 19. The left end of the springs 20 is fixedly connected to the movable frame 16. After the chemical raw materials are crushed, they fall onto the filter screen 17. 4. While drawing in air, the air is discharged into the exhaust pipe 12. The increased air pressure in the exhaust pipe 12 pushes the piston 14 to the right. The piston 14 pushes the moving frame 16 through the push rod 15. The moving frame 16 compresses the spring 20 to the right, generating elastic potential energy. When the piston 14 moves to the rightmost end of the exhaust pipe 12, the airflow is discharged through the exhaust port 13, thereby reducing the air pressure. At this time, under the action of the elastic potential energy of the spring 20, the moving frame 16 returns to its original position. This process is repeated to achieve the left and right movement of the filter screen 17, which screens the crushed chemical raw materials. Qualified materials are discharged through the discharge port 2 30, and unqualified materials are discharged through the discharge port 18, so as to facilitate the rapid screening of materials and avoid excessive accumulation of materials on the filter screen 17, which may cause blockage.

[0029] A support plate 21 is fixedly installed on the right side of the housing 1. A motor 22 is fixedly installed on the upper part of the support plate 21. The output shaft of the motor 22 is movably sleeved with the inner cavity of the housing 1. A gear 23 is fixedly sleeved on the output shaft of the motor 22. A gear 24 is meshed with the front extension of the gear 23. A rotating shaft 25 is fixedly sleeved on the left side of the gear 24. The rotating shaft 25 is movably sleeved with the inner cavity of the housing 1. A crushing roller 26 is fixedly sleeved on the output shaft of the motor 22 and the rotating shaft 25 respectively. The crushing roller 26 is located directly above the filter screen 17. Five crushing rings 27 are evenly fixedly sleeved on the crushing roller 26. The outer extension of the crushing rings 27 is evenly... The device is equipped with eight crushing claws 28. A crushing ring 27 includes a ring body 271. The ring body 271 has uniformly spaced grooves 272 extending outwards. The inner cavity of the grooves 272 has sliding grooves 273 on its left and right sides. Four threaded holes 274 are provided on the left and right sides of the grooves 272, located before and after the sliding grooves 273. Each crushing claw 28 includes a claw body 281. A fixing block 282 is fixedly connected to the claw body 281. The fixing block 282 fits into the grooves 272. Ribs 283 are fixedly installed on the left and right sides of the fixing block 282. The ribs 283 are connected to the sliding grooves 273. The groove 273 fits into the groove. The fixing block 282 has two threaded holes 284, with the left and right sides corresponding to the threaded hole 274. The front and rear parts of the housing 1 are connected by shafts to inspection plates 29. A discharge port 30 is located at the bottom of the inner cavity of the housing 1. Four support rods 31 are evenly fixed around the discharge port 30 at the bottom of the housing 1. Chemical raw materials are placed into the inner cavity of the housing 1 through the inlet 2. The motor 22 is turned on, driving gear 23 to rotate. The meshing of gear 23 and gear 24 drives the rotating shaft 25 to rotate, causing the front... The two rear crushing rollers 26 rotate in opposite directions. When the crushing rollers 26 rotate, they drive the crushing claws 28 to crush the chemical raw materials. When maintaining the device, the inspection plate 29 can be opened to maintain the crushing mechanism. The bolts can be rotated to remove the crushing mechanism from the threaded hole 274 and the threaded hole 284. At this time, the fixing block 282 can be removed from the groove 272, thereby replacing the claw body 281 with large wear. The above operation is reversed during installation. This avoids the need to disassemble the entire crushing mechanism for replacement during maintenance, reduces maintenance costs and time, and helps to improve the maintenance efficiency of the device.

[0030] Working principle: Chemical raw materials are placed into the inner cavity of the housing 1 through the feed inlet 2. The motor 22 is turned on, driving gear 1 23 to rotate. The meshing of gear 1 23 and gear 2 24 drives the rotating shaft 25 to rotate, causing the two crushing rollers 26 to rotate in opposite directions. When the crushing rollers 26 rotate, they drive the crushing claws 28 to crush the chemical raw materials. The dust generated by crushing the chemical raw materials in the inner cavity of the housing 1 is sucked into the dust collection chamber 3 by the fan 4. The current valve 6 is opened, so that the DC power supply 5 releases DC electricity to the electrode plate 7, so that an electrostatic field is formed on the electrode plate 7, thereby adsorbing the sucked-in dust. During cleaning and maintenance, the valve 8 is opened and the current valve 6 is closed to make the electrostatic field on the electrode plate 7 disappear. The vibrating motor on the electrode plate 7 is started, so that the dust on the electrode plate 7 falls off. The dust falls into the inner cavity of the dust collection box 10 along the dust discharge pipe 9. The cover plate 11 is opened to clean the dust. After the chemical raw materials are crushed, they fall onto the filter screen 17. The fan 4 draws in air while simultaneously... Air is discharged into the exhaust pipe 12, increasing the air pressure and pushing the piston 14 to the right. The piston 14, connected by the push rod 15, pushes the moving frame 16, which compresses the spring 20 to the right, generating elastic potential energy. When the piston 14 moves to the rightmost end of the exhaust pipe 12, the airflow is discharged through the exhaust port 13, thus reducing the air pressure. At this time, under the action of the elastic potential energy of the spring 20, the moving frame 16 returns to its original position. This process is repeated to move the filter screen 17 left and right, screening the crushed chemical raw materials. Qualified materials are discharged through the discharge port 2 30, and unqualified materials are discharged through the discharge port 1 18. When maintaining the device, the inspection plate 29 can be opened to maintain the crushing mechanism. The bolts can be rotated to remove it from the threaded hole 1 274 and the threaded hole 2 284. At this time, the fixing block 282 can be removed from the groove 2 272, thereby replacing the claw body 281 with large wear. The above operation is reversed during installation.
