Description

Technical Field

[0001] This invention belongs to the technical field of dry quenching coke, specifically a primary dust collector for dry quenching coke. Background Technology

[0002] Dry quenching, as opposed to wet quenching, refers to a quenching method that uses inert gas to cool red-hot coke. In the dry quenching process, red-hot coke at 1000℃ is loaded from the top of the dry quenching furnace, and low-temperature inert circulating gas at 130℃ is blown into the red-hot coke layer of the cooling section of the dry quenching furnace by a circulating fan to absorb the sensible heat of the red-hot coke. The cooled coke (below 200℃) is discharged from the bottom of the dry quenching furnace. The high-temperature inert gas coming out of the annular flue of the dry quenching furnace flows through the dry quenching boiler for heat exchange, and the boiler generates steam. The cooled inert gas is then blown back into the dry quenching furnace by a circulating fan. The inert gas is circulated and reused in a closed system. During the exchange process, a primary dust collector is used to remove large particles in the gas by gravity.

[0003] However, traditional primary dust collectors still have some shortcomings in practical use. For example, firstly, traditional primary dust collectors use gravity dust collection, using a baffle to change the direction of airflow and promote the separation of large particles from the gas. This method can only remove some large particles, while small particles will still flow out with the gas, so the dust removal effect is not good. Secondly, traditional primary dust collectors lack automatic cleaning devices. When the dust collector is used for a long time, its interior will be filled with dirt. If it is not cleaned in time, it will affect the dust removal effect. Thirdly, traditional primary dust collectors lack a device for processing particles. After removing large particles, the dust collector is directly conveyed out, which leads to the trouble of manual secondary processing later. Summary of the Invention

[0004] In view of the shortcomings of existing technologies, the purpose of this invention is to provide a primary dust collector for dry quenching coke, which solves the problems of poor dust removal effect, inability to automatically clean the interior and inability to handle particles in traditional primary dust collectors.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a primary dust collector for dry quenching coke, comprising a dust collection box, an input cylinder connected to one side of the dust collection box, a blower fixedly connected to one side of the input cylinder, a gas output cylinder connected to the other side of the dust collection box, a replacement cover movably connected to the top of the dust collection box, an opening in the top of the replacement cover, a slider movably connected inside the opening, a fixing plate B fixedly connected to the bottom of the slider, a bolt threaded inside the fixing plate B, a connecting frame fixedly connected to the top of the slider, a vibration motor fixedly connected to the bottom of the connecting frame, a conveying pipe connected to one side of the dust collection box, a water pump fixedly connected to the input end of the conveying pipe, a water pump connected to the input end of the water pump, and a water tank fixedly connected to the input end of the water pump. A fixed frame is fixedly connected to the bottom of the dust collection box. A fixed block is fixedly connected to the top inside the dust collection box. A connecting plate is movably connected to one side of the fixed block. Sliding grooves are opened on both sides of the connecting plate. A connecting rod is fixedly connected to the top of the connecting plate. A fixed plate A is fixedly connected to the top of the connecting plate. An iron mesh frame is fixedly connected to the bottom of the connecting plate. A filter bag is fixedly connected to the outside of the iron mesh frame. A limiting air plate is fixedly connected inside the dust collection box. A connecting pipe is connected inside the dust collection box. A water spray pipe is connected to one side of the connecting pipe. A shredding cylinder is fixedly connected to the bottom of the dust collection box. A shredding motor is fixedly connected to the bottom of the shredding cylinder. A dust output cylinder is connected to the bottom of the shredding cylinder. A rotating shaft is movably connected inside the shredding cylinder. A shredding blade is fixedly connected to one side of the rotating shaft.

[0006] Preferably, the end of the connecting rod away from the connecting plate is connected to the top of the fixing plate B.

[0007] By adopting the above technical solution, the advantages are that the added filter bag and vibration motor replace the traditional baffle to remove particles from the gas. The filter bag can not only adsorb large particles but also small particles, thus greatly improving the dust removal effect. The vibration motor can be activated to drive the filter bag to vibrate when the filter bag needs to remove dirt, thereby achieving an automatic cleaning effect and avoiding the trouble of manual cleaning.

[0008] Preferably, grooves are provided on both sides of the hole, and the dimensions of the slider are adapted to the dimensions of the grooves.

[0009] The advantage of adopting the above technical solution is that by adding a slider, the purpose is to prevent the dust collection box from vibrating when the vibrating motor drives the filter bag to vibrate, thereby ensuring that the dust collection box remains stable during the vibration cleaning process.

[0010] Preferably, an iron plate is fixedly connected to the top of the slider, and the end of the bolt away from the fixed plate B passes through the interior of the slider and connects to the interior of the iron plate.

[0011] The advantage of adopting the above technical solution is that the added bolts allow the connecting frame and the vibration motor to be removed from the top of the replacement cover, thus facilitating the replacement of the filter bag. At the same time, during operation, the connecting frame and the connecting rod can be connected, which facilitates the operation of the vibration motor.

[0012] Preferably, the output end of the pulverizing motor passes through the bottom of the pulverizing cylinder and is connected to one end of the rotating shaft.

[0013] The advantage of adopting the above technical solution is that by adding a crushing motor, the particles separated from the gas can be crushed by the action of the crushing blade, which facilitates the subsequent processing of the particles.

[0014] Preferably, there are two dust output cylinders.

[0015] By adopting the above technical solution, the advantage is that by adding two output cylinders, the crushed particles can be made to flow out of the dust collection box quickly, thereby avoiding the problem of particle backflow.

[0016] Preferably, the end of the delivery pipe away from the water pump passes through the side wall of the dust collector and is connected to one side of the connecting pipe.

[0017] By adopting the above technical solution, the advantage lies in the fact that by adding a water pump and spray pipe, when the filter bag is used for a long time, the inside will be filled with dust. This dust will block the fine pores of the filter bag, thus affecting the dust removal effect of the filter bag. At this time, the water pump is used to deliver water to the inside of the spray pipe to clean the filter bag, thereby removing this dust and avoiding the trouble of manual cleaning. At the same time, the inner wall of the dust collection box can also be cleaned, thus avoiding the trouble of manual cleaning of the inner wall of the dust collection box.

[0018] Preferably, the output end of the input cylinder passes through the side wall of the dust collector and is connected to one side of the air limiting plate.

[0019] By adopting the above technical solution, the advantage is that by adding the air limiting plate, the gas entering from the input cylinder can be fixedly input onto the filter bag, thereby avoiding the problem of some gas flowing out directly without being filtered.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The filter bag and vibration motor are designed to replace traditional baffles for removing particles from the gas. The filter bag not only adsorbs large particles but also small particles, greatly improving the dust removal effect. The vibration motor is activated to vibrate the filter bag when it needs cleaning, achieving automatic cleaning and avoiding the need for manual cleaning. The slider prevents the dust collection box from vibrating when the motor drives the filter bag, ensuring stability during the cleaning process. The bolts allow the connecting frame and vibration motor to be removed from the top of the replacement cover, facilitating filter bag replacement. During operation, the connecting frame and connecting rod also connect, further facilitating the operation of the vibration motor.

[0022] 2. The set-in crushing motor can crush the particles separated from the gas using the crushing blades, which facilitates the subsequent processing of the particles. The set-in two output cylinders can make the crushed particles flow out of the dust collection box quickly, thereby avoiding the problem of particle backflow.

[0023] 3. With the water pump and spray pipe installed, when the filter bag is used for a long time, dust will accumulate inside. This dust will clog the fine pores of the filter bag, thus affecting the dust removal effect. At this time, the water pump delivers water to the inside of the spray pipe to clean the filter bag, thereby removing the dust and avoiding the trouble of manual cleaning. At the same time, it can also clean the inner wall of the dust collection box, thus avoiding the trouble of manual cleaning of the inner wall of the dust collection box. The air limiting plate installed can make the gas entering from the input cylinder enter the filter bag in a fixed way, thereby preventing the problem of some gas flowing out directly without being filtered.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1-6As shown, the dry quenching coke primary dust collector includes a dust collection box 1. An input cylinder 2 is connected to one side of the dust collection box 1, and a blower 3 is fixedly connected to one side of the input cylinder 2. A gas output cylinder 4 is connected to the other side of the dust collection box 1. A replacement cover 13 is movably connected to the top of the dust collection box 1. An opening 14 is provided on the top of the replacement cover 13. A slider 15 is movably connected inside the opening 14. A fixing plate B27 is fixedly connected to the bottom of the slider 15. Bolts 28 are threaded inside the fixing plate B27. A connecting frame 16 is fixedly connected to the top of the slider 15. A vibration motor 17 is fixedly connected to the bottom of the connecting frame 16. A conveying pipe 6 is connected to one side of the dust collection box 1. A water pump 10 is fixedly connected to the input end of the conveying pipe 6. A water pump 11 is connected to the input end of the water pump 10. A water tank 12 is fixedly connected to the input end of the water pump 11. A water tank 12 is fixedly connected to the bottom of the dust collection box 1. A fixed frame 5 is fixedly connected to the top of the dust collector 1. A connecting plate 19 is movably connected to one side of the fixed block 18. Sliding grooves 21 are opened on both sides of the connecting plate 19. A connecting rod 29 is fixedly connected to the top of the connecting plate 19. A fixed plate A20 is fixedly connected to the top of the connecting plate 19. An iron mesh frame 23 is fixedly connected to the bottom of the connecting plate 19. A filter bag 22 is fixedly connected to the outside of the iron mesh frame 23. A limited air plate 24 is fixedly connected to the inside of the dust collector 1. A connecting pipe 25 is connected to the inside of the dust collector 1. A water spray pipe 26 is connected to one side of the connecting pipe 25. A crushing cylinder 7 is fixedly connected to the bottom of the dust collector 1. A crushing motor 9 is fixedly connected to the bottom of the crushing cylinder 7. A dust output cylinder 8 is connected to the bottom of the crushing cylinder 7. A rotating shaft 30 is movably connected to the inside of the crushing cylinder 7. A crushing blade 31 is fixedly connected to one side of the rotating shaft 30.

[0033] The working principle of the above technical solution is as follows:

[0034] First, gas is input into the input cylinder 2. Then, the blower 3 blows the gas into the dust collector 1. Simultaneously, the air restrictor 24 causes all the gas to enter the filter bag 22. The filter bag 22 then filters the particles carried in the gas and transports them to the gas output cylinder 4 for discharge. Later, when too many particles accumulate in the filter bag 22, the vibration motor 17 is activated, causing the connecting frame 16 to vibrate the connecting rod 29. At this time, both ends of the connecting plate 19 will move back and forth inside the fixing block 18. The movement of the filter bag 22 will cause the iron mesh frame 23 to vibrate, causing the particles on the filter bag 22 to fall into the crushing cylinder 7. Then, the crushing motor 9 will be activated to cause the crushing blade 31 to crush the particles in the crushing cylinder 7, which is beneficial for particle processing. After that, the crushed particles will flow out from the dust output cylinder 8. Finally, when the filter bag 22 has been used for too long, the water pump 10 can be activated to deliver water to the water spray pipe 26. At this time, the water spray pipe 26 will spray water to clean the filter bag 22, thus avoiding the trouble of manual cleaning.

[0035] In another implementation scheme, such as Figure 1-6 As shown, the end of the connecting rod 29 away from the connecting plate 19 is connected to the top of the fixing plate B27.

[0036] By adding a filter bag 22 and a vibration motor, the filter bag 22 replaces the traditional baffle-type filter for removing particles from the gas. It can not only adsorb large particles onto the filter bag 22, but also small particles, thus greatly improving the dust removal effect. The vibration motor is used to drive the filter bag 22 to vibrate when it needs to remove dirt, thereby achieving an automatic cleaning effect and avoiding the trouble of manual cleaning.

[0037] In another implementation scheme, such as Figure 1-6 As shown, grooves are provided on both sides of the hole 14, and the dimensions of the slider 15 are adapted to the dimensions of the grooves.

[0038] The purpose of adding slider 15 is to prevent the dust collection box 1 from vibrating when the vibrating motor drives the filter bag 22 to vibrate, thereby ensuring that the dust collection box 1 remains stable during the vibration cleaning process.

[0039] In another implementation scheme, such as Figure 1-6 As shown, an iron plate is fixedly connected to the top of the slider 15, and the end of the bolt 28 away from the fixed plate B27 passes through the interior of the slider 15 and connects to the interior of the iron plate.

[0040] The purpose of adding bolts 28 is to allow the connecting frame 16 and the vibration motor to be removed from the top of the replacement cover 13, thereby facilitating the replacement of the filter bag 22. At the same time, it also allows the connecting frame 16 and the connecting rod 29 to be connected during operation, thereby facilitating the operation of the vibration motor.

[0041] In another implementation scheme, such as Figure 1-6 As shown, the output end of the pulverizing motor 9 passes through the bottom of the pulverizing cylinder 7 and is connected to one end of the rotating shaft 30.

[0042] By adding a crushing motor 9, the particles separated from the gas can be crushed by the crushing blade 31, which facilitates the subsequent processing of the particles.

[0043] In another implementation scheme, such as Figure 1-6 As shown, there are two dust output cylinders 8.

[0044] By adding two output cylinders, the crushed particles can be made to flow out of the dust collection box 1 quickly, thus avoiding the problem of particle backflow.

[0045] In another implementation scheme, such as Figure 1-6 As shown, the end of the delivery pipe 6 away from the water pump 10 passes through the side wall of the dust collector 1 and is connected to one side of the connecting pipe 25.

[0046] With the addition of water pump 10 and water spray pipe 26, when the filter bag 22 is used for a long time, the inside will be filled with dust. This dust will block the fine pores of the filter bag 22, thus affecting the dust removal effect of the filter bag 22. At this time, the water pump 10 is used to deliver water to the inside of the water spray pipe 26 to clean the filter bag 22, thereby removing the dust and avoiding the trouble of manual cleaning. At the same time, the inner wall of the dust collection box 1 can also be cleaned, thus avoiding the trouble of manual cleaning of the inner wall of the dust collection box 1.

[0047] In another implementation scheme, such as Figure 1-6 As shown, the output end of the input cylinder 2 passes through the side wall of the dust collector 1 and is connected to one side of the air limiting plate 24.

[0048] By adding the air restrictor 24, the gas entering from the input cylinder 2 can be directed to the filter bag 22 in a fixed manner, thereby avoiding the problem of some gas flowing out directly without being filtered.

[0049] The working principle and usage process of this invention are as follows: First, gas is input into the input cylinder 2. Then, the blower 3 blows the gas into the dust collector 1. Simultaneously, the air limiting plate 24 ensures that all the gas enters the filter bag 22. The filter bag 22 then filters the particles carried in the gas and transports them to the gas output cylinder 4 for discharge. When too many particles accumulate in the filter bag 22, the vibration motor 17 is activated, causing the connecting frame 16 to drive the connecting rod 29 to vibrate. At this time, both ends of the connecting plate 19 will vibrate against the fixed block 1. The internal movement of filter bag 22 causes the iron mesh frame 23 to vibrate, causing the particles on filter bag 22 to fall into the grinding cylinder 7. Then, the grinding motor 9 is activated to cause the grinding blade 31 to grind the particles in the grinding cylinder 7, which facilitates the processing of the particles. Afterward, the ground particles will flow out from the dust output cylinder 8. Finally, when filter bag 22 has been used for too long, water pump 10 can be activated to deliver water to water spray pipe 26. At this time, water spray pipe 26 will spray water to clean filter bag 22, thus avoiding the trouble of manual cleaning.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
