Description

Technical Field

[0001] The invention relates to the technical field of air dust removal, and in particular to a high-efficiency cloth drum dust collector with airflow self-excited vibration auxiliary dust cleaning. Background Art

[0002] The cloth drum dust collector is a machine used for large-flow air treatment with high dust content, such as in crop processing plants, hay processing, feed and fertilizer processing, etc. The cloth drum dust collector will filter out a large amount of dust, which is attached to the outer surface of the cloth drum. The dust that does not fall under the action of gravity needs to be cleaned in time to prevent it from affecting the subsequent filtration process.

[0003] In the prior art, cloth tubes are generally cleaned by external air blowing, in which high-pressure gas is sprayed above the cloth tube array, and the dust is blown off when the gas passes through the cloth tube in the reverse direction. However, in the prior art, the air blowing pressure of the gas on each cloth tube is not the same. Some nozzles have high air pressure and good air blowing effect, while others have low gas pressure and limited cloth tube cleaning effect. Moreover, in the prior art, all cleaning requires external power supply and automatic or manual control, which increases the operating cost of the device. Summary of the invention

[0004] The object of the present invention is to provide a high-efficiency cloth-drum dust collector with airflow self-excited vibration auxiliary dust cleaning, so as to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions: A high-efficiency cloth-drum dust collector with airflow self-excited vibration auxiliary dust cleaning, the dust collector comprises an outer drum, a top drum, an air blowing assembly, a bottom drum, a drum plate, and a cloth drum, the bottom drum, the outer drum, and the top drum are sequentially connected from bottom to top, an air inlet is arranged on the side wall of the outer drum, an air outlet is arranged on the side of the top drum, the drum plate is horizontally arranged at the upper part of the outer drum, the drum plate is located on the path from the air inlet to the air outlet, a plurality of cloth drums are arranged on the drum plate, and an ash outlet is arranged at the bottom of the bottom drum; The air blowing assembly is arranged on the side of the top cylinder, and the air blowing assembly blows air to each cloth cylinder at intervals, and the blowing direction is from the top cylinder to the outer cylinder. The air blowing assembly has a blowing pressure balance structure.

[0006] The gas containing a large amount of dust enters the dust collector from the air inlet, penetrates into the center of the cloth tube from the surface of the cloth tube, then flows upward and gathers into the top tube, and then is discharged from the air outlet. The dust is blocked on the surface of the cloth tube, falls into the bottom tube by its own weight, and is then scraped by the scraper and discharged from a ash outlet on the lower surface of the bottom tube. Dust will also adhere to the surface of the cloth tube and affect the subsequent filtration effect. All high-pressure gas is blown periodically from all directions to allow the dust to fully fall from the surface of the cloth tube. The air blowing component is set on the outer wall of the top tube or the outer tube, and air blowing ports extend directly above all the cloth tubes. At the set time or when there is a need, a large amount of gas is sprayed in the reverse direction to pass through the mesh cloth of the cloth tube to blow off the dust on the surface. The air blowing component should ensure that all cloth tubes receive approximately the same air blowing pressure to prevent differences in the effect from affecting the differences in filtering performance of different cloth tubes.

[0007] The air blowing assembly includes an air tank, an air distribution seat, an air main pipe, and an air branch pipe. The air tank and the air distribution seat are both arranged on the outer wall of the top tube. The air main pipe is horizontally inserted into the top tube. Several air main pipes are arranged in parallel with each other and cover all the cloth tubes from above. Each air main pipe is downwardly provided with several air branch pipes. All the air branch pipes correspond to the cloth tubes one by one. One end of the air main pipe is connected through the air distribution seat to the air tank. The other end of the air main pipe is closed. The air tank is supplied with a pressure air source from the outside. The opening diameters on the same gas main pipe for connecting to the gas branch pipes change gradually, and the opening on the gas main pipe close to the gas tank is the largest.

[0008] The gas tank supplies pressurized gas to all gas mains, and the gas is sprayed out from the lower ends of all gas branch pipes when needed. The gas is filled into the cloth tube to shake off the dust on the surface. Some of the gas branch pipes on the same gas main are close to the gas tank, and some are far away from the gas tank. If the docking calibers are the same, the gas outlet pressure of the gas branch pipe at the far end will be smaller, affecting the air blowing effect. Therefore, this application gradually changes the caliber, the interface caliber is larger at the closer end, the gas outlet pressure is slightly reduced, and more pressure in the gas main pipe is retained at the farther end, and the gas outlet pressure at all positions is relatively uniform.

[0009] The tracheal tube is provided with an air hole on the side of the root where it is connected to the main air pipe.

[0010] When the trachea is jetting, there is a hole on the wall of the tube that can draw in the surrounding gas. The principle is similar to that of an ejector, which increases the amount of gas jetted from the trachea.

[0011] A solenoid valve is provided at the connecting end of the gas main pipe and the gas tank.

[0012] The solenoid valve controls the connection between the gas tank and the gas main, controls the gas blowing time interval, and performs an additional gas blow based on automatic control or manual operation to open the solenoid valve.

[0013] The ratio of the outer cylinder height to the diameter is 1~1.5.

[0014] If the outer cylinder is too high, it will affect the overall size of the dust collector and the installation conditions will be limited. If the outer cylinder is too short, it will affect the flow rate of dust-laden gas entering the outer cylinder, and also limit the length of the cloth cylinder and the filtration area. The gas entering the outer cylinder will not be processed in time, affecting the subsequent air intake. Therefore, a comprehensive aspect ratio of 1 to 1.5 is selected.

[0015] The cylinder plate is installed on the upper part of the outer cylinder in a floating manner. The gap between the cylinder plate and the outer cylinder at the floating installation position is blocked by a deformable filter. An oscillation component is arranged on the cylinder plate to generate periodic horizontal vibration.

[0016] When the cylinder plate is installed in a floating manner, mechanical vibration can shake off the dust on the surface of the cloth cylinder. The floating installation of the cylinder plate can be achieved by spring suspension. For example, a step ring is provided on the inner wall of the upper part of the outer cylinder. The step ring has a circumferential opening. The cylinder plate is suspended on the step ring by springs with hooks at both ends. There is a place between the outer edge of the cylinder plate and the edge of the step ring. An annular cloth is used to separate the lower part and the top cylinder of the outer cylinder to prevent the dust-containing gas from flowing through the gap. The oscillation component vibrates horizontally on the cylinder plate at intervals to shake off the dust.

[0017] The oscillation component includes a base plate, a pendulum rod, a hammer, a pneumatic traction module, and a swing spring. The base plate is fixed on the cylinder plate. The side of the base plate is hinged to the pendulum rod. The upper end of the pendulum rod is exposed from the upper edge of the base plate. The lower end of the pendulum rod is provided with a groove in the middle. A rotating pin is arranged in the groove. The axis of the rotating pin is parallel to the installation axis of the pendulum rod and both are horizontal. The upper section of the hammer is provided with a notch. The notch is inserted into the rotating pin. The swing spring is placed in the notch of the upper section of the hammer. One end of the swing spring is against the bottom surface of the notch, and the other end of the swing spring is against the rotating pin. An arc groove is arranged at the lower part of the side of the base plate. The arc center of the arc groove is located directly above the rotation center of the pendulum rod. The lower end of the hammer is an arc and slides along the arc groove. The pneumatic traction module is arranged on the cylinder plate. There are two pneumatic traction modules. The two pneumatic traction modules pull the upper end of the swing rod to swing between two swing limit positions at intervals. The pneumatic traction modules are driven by the gas discharged from the gas outlet.

[0018] The pneumatic traction module includes a cylinder, a fan, a traction rope, a gate, a jump spring, and a switch rope. The outer surface of the cylinder is connected to the cylinder plate through an extension rod, one end of the cylinder faces the air outlet, and the fan is rotatably installed in the cylinder. One end of the traction rope is wound around the fan shaft, and the other end of the traction rope is connected to one side of the upper end of the swing arm through a number of guide wheels. A jump spring is arranged on the traction rope, and the gate is vertically installed on the cylinder, and the gate is located at the end of the cylinder away from the air outlet. One end of the switch rope is fixed to the upper end of the gate, and the other end of the switch rope is connected to the traction rope. The connection position between the switch rope and the traction rope is located on the side of the jump spring close to the swing arm, and the traction ropes of the two pneumatic traction modules are respectively connected to the two sides of the swing arm.

[0019] The clean air flow after filtering by the cloth drum is blown out from the air outlet and passes through the pneumatic traction module on the path. Among the two pneumatic traction modules, only the pneumatic traction module that is about to pull the swing arm is in the open state, and one gate is in a high position. The airflow flows through the cylinder body to drive the internal fan to rotate, and the traction rope on the rotating shaft is twisted, the traction rope is shortened, and the jump spring is pulled to stretch. After the force accumulated in the jump spring is sufficient, the traction rope pulls the swing arm to swing quickly for a short time, and the jump spring is no longer in a stretched state, but retreats a short distance to the cylinder body and then is in a short state. The switch rope also retreats a distance backward, and the gate falls to close one pneumatic traction module. After the swing arm swings to a new extreme position, the traction rope on the other pneumatic traction module is pulled forward, the gate is opened, and airflow begins to pass through the front cylinder. The fan rotates, and the traction rope at the rotating shaft is continuously twisted until it can pull the swing arm to swing from one extreme position to another. In this way, gas passes through the two pneumatic traction modules alternately and continuously pulls the rocker arm to swing intermittently, realizing intermittent hammering of the hammer and generating mechanical vibration. This process is entirely achieved by the flow of the gas to be treated, and does not require additional power input. In some dust treatment conditions where the adhesion of dust to the cloth tube is not high, such as dust and debris with large particle size, straw debris and other air treatment, the air blowing component can completely replace the air blowing component. The air blowing component does not need to be run to maintain the efficient operation of the dust collector. For the treatment of finer ash-containing gases, the operation frequency of the air blowing component can also be reduced, saving external energy supply.

[0020] The hammer accounts for more than one-third of the weight of the base plate, pendulum, hammer, swing spring, and rotating pin. Except for the relatively independent pneumatic traction module in the oscillation assembly, the other components are installed tightly together. The high weight ratio of the hammer can make the single impact force when changing from the extreme position large, and have a better vibration effect.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention arranges a special air blowing assembly structure so that the outlet pressures of each branch pipe on the gas main pipe tend to be the same, and approximately equal air blowing operations are performed on all cloth tubes. The air holes on the sides of the roots of the air branches introduce more gas for air blowing, thereby maintaining the high filtering performance of the cloth tube; the oscillation assembly causes the mounting platform of the cloth tube to produce periodic horizontal vibrations, thereby removing additional dust by mechanical means, and under some working conditions, it can completely replace the air blowing assembly to achieve self-cleaning without power input.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] A high-efficiency cloth tube dust collector with airflow self-excited vibration auxiliary dust cleaning, the dust collector comprises an outer tube 1, a top tube 2, an air blowing assembly 3, a bottom tube 4, a tube plate 5, and a cloth tube 6, the bottom tube 4, the outer tube 1, and the top tube 2 are sequentially connected from bottom to top, an air inlet 11 is arranged on the side wall of the outer tube 1, an air outlet 21 is arranged on the side of the top tube 2, the tube plate 5 is horizontally arranged at the upper part of the outer tube 1, the tube plate 5 is located on the path from the air inlet 11 to the air outlet 21, a plurality of cloth tubes 6 are arranged on the tube plate 5, and an ash outlet is arranged at the bottom of the bottom tube 4; The air blowing assembly 3 is arranged on the side of the top tube 2. The air blowing assembly 3 blows air to each cloth tube 6 at intervals. The blowing direction is from the top tube 2 to the outer tube 1. The air blowing assembly 3 has a blowing pressure balance structure.

[0025] like Figure 1 , 2As shown, the gas containing a large amount of dust enters the dust collector from the air inlet 11, penetrates into the center of the cloth tube from the outer surface of the cloth tube 6, then flows upward and gathers into the top tube 2, and then is discharged from the device from the air outlet 11. The dust is blocked on the outer surface of the cloth tube 6, falls into the bottom tube 4 by its own weight, and is then scraped by the scraper and discharged from a ash outlet on the lower surface of the bottom tube 4. Dust will also adhere to the surface of the cloth tube 6 and affect the subsequent filtering effect. All high-pressure gas is blown periodically from all directions to allow the dust to fully fall from the surface of the cloth tube 6. The air blowing component 3 is arranged on the outer wall of the top tube 2 or the outer tube 1, and air blowing ports are extended one by one directly above all the cloth tubes 6. At the set time or when there is a need, a large amount of gas is sprayed in the reverse direction to pass through the mesh cloth of the cloth tube 6 to blow off the dust on the surface. The air blowing component 3 should ensure that all cloth tubes 6 receive approximately the same air blowing pressure to prevent differences in the effect from affecting the differences in filtering performance of different cloth tubes.

[0026] The air blowing assembly 3 includes an air tank 31, an air distribution seat 32, an air main pipe 33, and an air branch pipe 34. The air tank 31 and the air distribution seat 32 are both arranged on the outer wall of the top tube 2. The air main pipe 33 is horizontally inserted into the top tube 2. Several air main pipes 33 are arranged in parallel with each other and cover all the cloth tubes 6 from above. Each air main pipe 33 is downwardly provided with several air branch pipes 34. All the air branch pipes 34 correspond to the cloth tubes 6 one by one. One end of the air main pipe 33 is connected through the air distribution seat 32 to the air tank 31. The other end of the air main pipe 33 is closed. The air tank 31 is supplied with a pressure air source from the outside. The opening diameters of the same gas main pipe 33 for connecting to the gas branch pipe 34 change gradually, and the opening of the gas main pipe 33 close to the gas tank 31 is the largest.

[0027] like Figure 2 , 3 As shown, the gas tank 31 supplies pressurized gas to all gas main pipes 33, and the gas is sprayed out from the lower ends of all gas branch pipes 34 when needed. The gas is filled into the cloth tube 6 to shake off the dust on the surface. Some of the gas branch pipes 34 on the same gas main pipe 33 are close to the gas tank 31, and some are far away from the gas tank 31. If the docking calibers are the same, the outlet pressure of the gas branch pipe 34 at the far end will be smaller, affecting the air blowing effect. Therefore, the present application gradually changes the caliber, the interface caliber is larger at the closer part, the outlet pressure is slightly reduced, and more pressure in the gas main pipe 33 is retained at the farther part, and the outlet pressure at all positions is relatively uniform.

[0028] The air branch pipe 34 is provided with an air hole 35 on the side of the root portion where it is connected to the main air pipe 33 .

[0029] like Figure 2 , 3 As shown, when the tracheal tube 34 is jetting, there is an air hole 35 on the tube wall to guide the surrounding gas in, the principle is similar to that of an ejector, and the jetting gas volume of the tracheal tube 34 is increased.

[0030] A solenoid valve is provided at the connecting end of the gas main pipe 33 and the gas tank 31 .

[0031] The electromagnetic valve controls the connection between the gas tank 31 and the gas main pipe 33, controls the air blowing time interval, and performs an additional air blowing based on automatic control or manual operation to open the electromagnetic valve.

[0032] The ratio of the height to the diameter of the outer cylinder 1 is 1 to 1.5.

[0033] If the outer tube 1 is too high, it will affect the size of the dust collector and the installation conditions will be limited. If the outer tube 1 is too short, it will affect the flow rate of dust-containing gas entering the outer tube 1, and also limit the length of the cloth tube and the filtration area. The gas entering the outer tube 1 will not be processed in time, affecting the subsequent air intake. Therefore, a comprehensive aspect ratio of 1 to 1.5 is selected.

[0034] The cylinder plate 5 is installed on the upper part of the outer cylinder 1 in a floating manner. The gap between the cylinder plate 5 and the outer cylinder 1 at the floating installation position is blocked by a deformable filter. An oscillation component 7 is arranged on the cylinder plate 5 to generate periodic horizontal vibration.

[0035] like Figure 1 , 2 As shown in , 4, when the cylinder plate 5 is installed in a floating manner, mechanical vibration can shake off the dust on the surface of the cloth cylinder 6. The floating installation of the cylinder plate 5 can be carried out by spring suspension. For example, a step ring 12 is arranged on the inner wall of the upper part of the outer cylinder 1. The step ring 12 has a circumferential opening. The cylinder plate 5 is suspended on the step ring 12 by springs with hooks at both ends. There is a place between the outer edge of the cylinder plate 5 and the edge of the step ring 12. An annular cloth is used to separate the lower part of the outer cylinder 1 and the top cylinder 2 to prevent the dust-containing gas from flowing through the gap. The oscillation component 7 vibrates horizontally on the cylinder plate 5 at intervals to shake off the dust.

[0036] The oscillation assembly 7 includes a base plate 71, a swing rod 72, a hammer 73, a pneumatic traction module 74, and a swing spring 75. The base plate 71 is fixed on the cylinder plate 5. The swing rod 72 is hinged on the side of the base plate 71. The upper end of the swing rod 72 is exposed from the upper edge of the base plate 71. The lower end of the swing rod 72 is provided with a groove in the middle. A rotating pin 76 is arranged in the groove. The axis of the rotating pin 76 is parallel to the installation axis of the swing rod 72 and both are horizontal. The upper section of the hammer 73 is provided with a notch, and the notch is inserted into the rotating pin 76. The swing spring 75 is placed in the notch of the upper section of the hammer 73. One end of the swing spring 75 is against the bottom surface of the notch, and the other end of the swing spring 75 is against the rotating pin. An arc groove 711 is arranged on the lower part of the side of the base plate 71. The arc center of the arc groove 711 is located directly above the rotation center of the swing rod 72. The lower end of the hammer 73 is an arc and slides along the arc groove 711. The pneumatic traction module 74 is arranged on the cylinder plate 5 . There are two pneumatic traction modules 74 . The two pneumatic traction modules 74 pull the upper end of the swing rod 72 to swing between two swing limit positions at intervals. The pneumatic traction modules 74 are driven by the gas discharged from the gas outlet 21 .

[0037] like Figure 1 ,5 As shown in FIG. 6 , the hammer 73 cannot rotate around the axis of the installation of the swing rod 72 because the center of the arc groove 711 is at a higher position. Figure 6 When the right extreme position is pulled to swing to the left, the rotating pin 76 at the lower end of the swing rod 72 is continuously squeezed into the groove of the upper section of the hammer 73, and the swing spring 75 is also continuously squeezed until the hammer 73 can rotate in the arc groove 711 with the rotating pin 76 as the center. Then the swing spring 75 is released at once, and the hammer 73 directly hits the other end of the arc groove 711. At this time, the swing rod 72 also swings directly and quickly to Figure 6 The leftmost side of the figure completes a vibration action, and the swinging power of the swing rod 72 comes from the traction force F of the pneumatic traction module 74 from both sides.

[0038] The pneumatic traction module 74 includes a cylinder 741, a fan 742, a traction rope 743, a gate 744, a jump spring 745, and a switch rope 746. The cylinder 741 is connected to the cylinder plate 5 through an extension rod. One end of the cylinder 741 faces the air outlet 21. The fan 742 is rotatably installed in the cylinder 741. One end of the traction rope 743 is wound around the rotating shaft of the fan 742. The other end of the traction rope 743 is connected to one side of the upper end of the swing rod 72 through a plurality of guide wheels. A jump spring 745 is provided, and a gate plate 744 is vertically installed on the cylinder 741. The gate plate 744 is located at the end of the cylinder 741 away from the air outlet 21. One end of a switch rope 746 is fixed to the upper end of the gate plate 744, and the other end of the switch rope 746 is connected to the traction rope 743. The connection position between the switch rope 746 and the traction rope 743 is located on the side of the jump spring 745 close to the rocker arm 72. The traction ropes 743 of the two pneumatic traction modules 74 are respectively connected to the two sides of the rocker arm 72.

[0039] like Figures 5 to 7 As shown, the clean air flow after being filtered by the cloth tube 6 is blown out from the air outlet and passes through the pneumatic traction module 74 on the path. Among the two pneumatic traction modules 74, only the pneumatic traction module 74 that is about to traction the swing rod 72 is in the open state. Figure 7 In the middle, the gate plate 744 at the rear is in a high position, and the airflow from the cylinder 741 drives the internal fan 742 to rotate, and the traction rope 743 on the rotating shaft is twisted, and the traction rope 743 is shortened, pulling the jump spring 745 to stretch. When the force accumulated in the jump spring 745 is sufficient, the traction rope 743 pulls the swing rod 72 to swing quickly for a short time, and the jump spring 745 is no longer in a stretched state, but retreats a short distance to the cylinder 741 and then is in a short state. The switch rope 746 also retreats a distance backward, and the gate plate 744 falls, Figure 7 After the pneumatic traction module 74 at the middle and rear is closed and the swing arm 72 swings to a new limit position, Figure 7The traction rope 743 on the front pneumatic traction module 74 is pulled forward, the gate 744 is opened, and air begins to flow through the front cylinder 741. The fan 742 rotates, and the traction rope 743 at the rotating shaft is continuously twisted until it can pull the swing rod 72 to swing from one extreme position to another extreme position. In this way, gas alternately passes through the two pneumatic traction modules 74 and continuously pulls the swing rod 72 to swing intermittently, realizing the interval hammering of the hammer 73 and generating mechanical vibration. This process is entirely achieved by the flow of the gas to be processed, and no additional power input is required. In some processing conditions where the dust has low adhesion to the cloth tube 6, such as dust and debris with large particle size, straw debris and other air treatment, it can completely replace the air blowing component 3. The air blowing component 3 does not need to be operated to maintain the efficient operation of the dust collector. For the treatment of finer ash-containing gas, it can also reduce the operation frequency of the air blowing component 3 and save external energy.

[0040] The hammer 73 accounts for more than one third of the weight of the base plate 71, the swing rod 72, the hammer 73, the swing spring 75, and the rotating pin 76. Except for the relatively independent pneumatic traction module 74 in the oscillation assembly 7, the other components are installed in a tight fit. The high weight proportion of the hammer 73 can make the single impact force when changing from the extreme position large, and have a better vibration effect.

[0041] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
