Description

Technical Field

[0001] The invention relates to the technical field of lubricating oil additives, in particular to a dust treatment device and application thereof in the production of lubricating oil additives. Background Art

[0002] In the production process of lubricant additives, dust will be generated during the pretreatment process involving crushing, grinding and screening of solid lubricant additives. As the pretreatment process proceeds, the dust will be distributed over a larger area in the processing workshop, and the dust concentration will become higher and higher, polluting the working environment of the production workshop and causing harm to the health of the staff.

The rotating shaft of the rotating motor 303 is provided with a filter layer 304. The rotating motor 303 drives the filter layer 304 to rotate. There are no less than four rotating motors 303. The number of filter layers 304 is the same as the number of rotating motors 303, and corresponds one-to-one to the rotating motors 303.

[0034] The top of the shell 1 is in an inverted bucket shape, and a flange is provided on the top of the shell 1. The shell 1 is fixedly connected to the dust inlet pipe through the flange. A fan is provided on the dust inlet pipe, and the particulate dust generated by the pretreatment of the lubricating oil additive processing workshop is transported into the shell 1 by the fan.

[0035] A guide plate 101 is provided on the inner side of the housing 1 . The guide plate 101 is located below the filter cartridge 5 . The guide plate 101 is bucket-shaped. Dust on the guide plate 101 moves downward along the slope of the guide plate 101 under the influence of natural gravity.

[0036] An extension tube 102 is provided at the bottom of the guide plate 101, and the inner lower surface of the extension tube 102 is inclined. A discharge pipe 103 is provided at the bottom of the extension tube 102. The end of the discharge pipe 103 away from the extension tube 102 passes through the shell 1 and is located outside the shell 1. A discharge valve is provided at the end of the discharge pipe 103 located outside the shell 1. The end of the discharge pipe 103 close to the extension tube 102 corresponds to the lowest point inside the extension tube 102.

An exhaust pipe 104 is provided at the top of one side of the extension tube 102, and the gas entering from the top of the shell 1 is discharged outwardly through the exhaust pipe 104.

[0037] An electric telescopic rod 404 is provided in the middle of the extension tube 102. The electric telescopic rod 404 provides support for the inner support column 302. At the same time, the inner support column 302, the outer ring 301 and the filter layer 304 are driven to move up and down synchronously through the electric telescopic rod 404. The telescopic end of the electric telescopic rod 404 is fixedly connected to the inner support column 302. The fixed end of the electric telescopic rod 404 is fixedly connected to the extension tube 102 through a support plate. A guide piece 1021 is provided on the inner side of the extension tube 102. The guide piece 1021 is bucket-shaped and is located between the exhaust pipe 104 and the spiral blade 403. The guide piece 1021 is used to reduce the impact of the gas flow on the dust below the guide piece 1021.

[0038] The rotating component 4 includes a rotating motor 401. The rotating shaft of the rotating motor 401 is provided with a support shaft 402. The top of the support shaft 402 passes through the bottom of the extension tube 102 and the inner support column 302 in sequence. A spiral blade 403 is provided on the circumference of the support shaft 402. When the spiral blade 403 rotates, the dust accumulated in the extension tube 102 is dispersed to the surroundings. When the discharge valve on the discharge pipe 103 starts, the dust in the extension tube 102 is continuously discharged outward during the reverse rotation of the spiral blade 403. The discharge pipe 103 is set obliquely.

[0039] One end of the adsorption plate 203 away from the inner cylinder 202 is rotatably connected to the rotating ring 201, and the adsorption component 2 is rotatably connected to the top of the shell 1. A bearing is provided on the inner side of the top of the shell 1. The outer ring of the bearing is fixedly connected to the shell 1, and the inner ring of the bearing is fixedly connected to the rotating ring 201. A locking mechanism is provided between the outer ring of the bearing and the inner ring of the bearing. The locking mechanism is an electromagnetic lock. The locking mechanism is used to fix the outer ring of the bearing and the inner ring of the bearing. Through the setting of the bearing, when the angle of the adsorption plate 203 in the adsorption component 2 is adjusted to an inclined state, the adsorption component 2 rotates when the gas passes through the inclined adsorption plate 203.

[0040] One end of the exhaust pipe 104 away from the extension tube 102 passes through the shell 1 and is located on the outside of the shell 1. An exhaust valve is provided at the end of the exhaust pipe 104 away from the shell 1. A filter is provided on the side of the exhaust pipe 104 close to the extension tube 102. The exhaust valve controls the connection between the exhaust pipe 104 and the outside of the shell 1. The filter is set to block dust at the connection between the exhaust pipe 104 and the extension tube 102.

[0041] When in use, the shell 1 is fixedly connected to the dust inlet pipe through a flange, and the end of the dust inlet pipe away from the shell 1 is connected to the lubricant additive processing workshop. The fan on the dust inlet pipe is started to continuously transport the particulate dust generated by the pretreatment (such as crushing, grinding or screening) of the lubricant additive processing workshop to the shell 1, thereby avoiding the problem of large-scale dust generated by the lubricant additive processing production line floating in the air, improving the air quality of the lubricant additive processing workshop, and reducing the harm to the health of workers.

[0042] The dust concentration in the gas entering the shell 1 is detected by a dust concentration sensor, and thresholds C1 and C2 are preset in the dust concentration sensor, wherein a dust concentration below the threshold C1 is low, a dust concentration between C1 and C2 is normal, and a dust concentration above the threshold C2 is high.

[0043] In the initial stage of pretreatment of lubricant additive raw materials in the lubricant additive processing workshop, the dust concentration in the workshop is maintained at a relatively low level. The dust concentration sensor detects that the dust concentration in the gas entering the shell 1 has not reached C1. At this time, it is actively judged that the dust concentration in the filter cartridge 5 is relatively low. Driven by the angle adjustment motor, the adsorption plate 203 is kept vertical. When the gas entering the shell 1 passes through the adsorption plate 203, the dust in the gas is adsorbed by the electrostatic adsorption layer on the adsorption plate 203. At the same time, the rotating motor 303 drives the filter layer 304 to rotate, so that the filter layer 304 remains vertical. The vertically arranged adsorption plate 203 and the filter layer 304 are used to accelerate the gas passing efficiency, reduce the operating energy consumption of the dust treatment device under low dust concentration state, and the gas after passing through the adsorption plate 203 continues to flow downward and is discharged to the outside through the exhaust pipe 104 to the next treatment process.

[0044] When the dust concentration sensor detects that the dust concentration entering the shell 1 is between the threshold C1 and the threshold C2, it indicates that the dust concentration in the shell 1 is normal. At this time, the locking mechanism maintains the lock between the outer ring and the inner ring of the bearing. Driven by the angle adjustment motor in the inner cylinder 202, the adsorption plate 203 is inclined, and the electrostatic adsorption layer on the adsorption plate 203 remains energized. When the gas flows from top to bottom using the inclined adsorption plate 203, the dust in the gas will directly collide with and be adsorbed on the electrostatic adsorption layer, increasing the contact area between the gas and the electrostatic adsorption layer, thereby increasing the adsorption opportunity of the dust in the gas on the electrostatic adsorption layer, and improving the dust capture efficiency in the shell 1. At the same time, the filter layer 304 rotates driven by the rotating motor 303 to keep the filter layer 304 horizontal. The dust in the gas after passing through the adsorption plate 203 is filtered by multiple filter layers 304 and the filter cartridge 5, and the gas after passing through the filter layer 304 is discharged outward through the exhaust pipe 104.

[0045] However, when the dust concentration in the filter cartridge 5 is high, the dust will quickly accumulate on the filter layer 304 and the filter cartridge 5 driven by the gas. As the dust continues to accumulate, the resistance of the gas passing through the filter layer 304 and the filter cartridge 5 will become greater and greater, resulting in an increasing dust processing load in the housing 1. In this regard, the following improvements are made:

[0046] When the dust concentration sensor detects that the dust concentration entering the shell 1 reaches the threshold value C2, it actively determines that the dust concentration in the gas entering the shell 1 is high, and the adsorption plate 203 remains tilted at an unchanged angle under the control of the angle adjustment motor in the inner cylinder 202. The locking mechanism in the bearing is closed, and the restriction between the outer ring and the inner ring of the bearing is released. At this time, the airflow passing through the oblique adsorption plate 203 will drive the oblique adsorption plate 203, the rotating ring 201 and the inner ring of the bearing to rotate. During the rotation of the adsorption plate 203, the downward flow rate of the gas passing through the adsorption plate 203 is increased. At the same time, the filter layer 304 is kept horizontal under the control of the rotating motor 303, and the telescopic end of the electric telescopic rod 404 drives the inner support column 302 and the outer ring 301 to rotate. 01 and the filter layer 304 move upward a short distance, and the gas above the filter component 3 is pushed upward during the upward movement of the filter component 3, forming a counteracting effect with the gas that passes through the adsorption plate 203 and moves downward. By compressing the gas in the filter cartridge 5, the flow direction of the airflow is changed, and the gas in the counteracting area in the filter cartridge 5 is diffused to the surroundings, and the filter cartridge 5 is used to improve the filtration efficiency of dust in the gas. As the telescopic end of the electric telescopic rod 404 repeatedly extends and retracts, the filter component 3 is driven to move up and down repeatedly, and the gas in the filter cartridge 5 is repeatedly compressed, so that the gas in the filter cartridge 5 continues to diffuse to the surroundings, thereby improving the utilization rate of the side wall of the filter cartridge 5, and allowing more gas to continue to pass through the filter cartridge 5 for filtration, so as to improve the treatment efficiency of high-concentration dust.

[0047] It should be noted that, in the process of treating low-concentration and normal-concentration dust, most of the gas directly passes vertically downward through the filter assembly 3 for treatment, and the overall utilization rate of the filter cartridge 5 is low.

[0048] A gas flow sensor is provided at a position corresponding to the bottom of the filter cartridge 5 inside the shell 1. The gas flow sensor detects the blockage state of the filter cartridge 5 according to the gas flow passing through the filter cartridge 5. A flow threshold value Q1 is preset in the gas flow sensor. When the gas flow sensor detects that the flow threshold value is lower than Q1, it indicates that the filter cartridge 5 is blocked and needs to be cleaned. In this regard, there is a gap between the filter cartridge 5 and the guide plate 101. When the gas flow sensor detects that the flow threshold value is lower than Q1, an air intake valve is provided on the dust inlet pipe. At this time, the air intake valve and the fan on the dust inlet pipe are temporarily closed, and the electric telescopic rod 404 drives the filter assembly 3 to move up and down, and the rotating motor 401 drives the spiral blade 403 to start and stop repeatedly through the support shaft 402. Specifically, the filter cartridge 5 is elastic. When the electric telescopic rod 404 drives the filter assembly 3 to move downward quickly, the rotating motor 401 starts to drive the spiral blade 403 to rotate forward, thereby generating an upward airflow. A part of the airflow passes through the filter layer 304 and flows to the filter The two air flows do not interfere with each other. Secondly, the electric telescopic rod 404 drives the filter assembly 3 to move slowly upward for a short distance, and then drives the filter assembly 3 to move downward quickly, so that negative pressure is generated in the filter cartridge 5. The upward airflow generated when the spiral blade 403 rotates forward and the negative pressure generated in the filter cartridge 5 when the filter layer 304 moves downward can be used to remove the dust attached to the filter cartridge 5. Furthermore, the negative pressure generated in the filter cartridge 5 when the electric telescopic rod 404 drives the filter assembly 3 to move downward quickly causes the filter cartridge 5 to produce elastic deformation. When the electric telescopic rod 404 drives the filter assembly 3 to move slowly upward, the shape of the filter cartridge 5 is restored. In the process of the electric telescopic rod 404 driving the filter assembly 3 to move up and down, the elastic deformation of the filter cartridge 5 is used to make the filter cartridge 5 vibrate, thereby improving the dust shedding efficiency of the inner wall of the filter cartridge 5.

[0049] At the same time, when the electric telescopic rod 404 drives the filter assembly 3 to move downward quickly, the airflow at the bottom of the filter assembly 3 forms an upward impact force on the filter layer 304 in the filter assembly 3, clearing the filter layer 304 and preventing continuous accumulation of dust on the filter cartridge 5 and the filter layer 304 to affect the treatment of the dust.

[0050] After the preset time for cleaning the dust on the filter layer 304 and the filter cartridge 5 is reached, the rotating motor 401 is turned off, the driving of the spiral blade 403 is stopped, the air inlet valve and the fan on the dust inlet pipe are reopened, and the gas from the lubricating oil additive processing workshop is transported into the shell 1, so that the airflow on the top of the filter component 3 and the airflow between the adsorption plate 203 continue to form a counter-attack and diffuse in all directions, and the dust in the high-concentration gas continues to be filtered.

[0051] To sum up, when the dust concentration sensor detects that the dust concentration in the shell 1 exceeds the standard, the adsorption plate 203 remains tilted, and the locking mechanism is released from the locked state. When the airflow passes through the gap between the adsorption plates 203, the adsorption component 2 is driven to rotate, and the electric telescopic rod 404 drives the filter component 3 to move up and down, which offsets the airflow formed by the adsorption plate 203, thereby enhancing the dust filtering efficiency of the filter cartridge 5.

[0052] At the same time, by repeatedly moving the filter assembly 3 up and down and intermittently starting the rotating motor 401 to drive the spiral blade 403 to rotate rapidly, the gas above the spiral blade 403 repeatedly passes through the filter cartridge 5 and the filter layer 304, thereby cleaning the dust on the filter layer 304 and the filter cartridge 5, maintaining smooth gas circulation, and improving the processing efficiency of high-concentration dust.

[0053] When the lubricating oil additive processing workshop stops processing, since dust is adsorbed on the adsorption plate 203 and the filter layer 304, the existence of such dust affects the treatment effect of dust in the gas during the operation of the subsequent dust treatment device. The following improvements are made:

[0054] After the lubricating oil additive is processed, the telescopic end of the electric telescopic rod 404 drives the filter assembly 3 to move continuously upward through the inner support column 302, so that the filter assembly 3 is close to the adsorption assembly 2. At this time, the electrostatic adsorption layer on the adsorption plate 203 is powered off, and the angle of the adsorption plate 203 is adjusted to a vertical state. The rotating motor 303 drives the filter layer 304 to rotate vertically, and the top of the filter layer 304 contacts the adsorption plate 203. The rotating motor 303 drives the filter layer 304 to rotate repeatedly clockwise and counterclockwise. During the repeated rotation of the filter layer 304, a reverse impact is formed on the adsorption plate 203. The vibration generated by the repeated knocking will shake the dust on the adsorption plate 203 and the filter layer 304 downward. When the electric telescopic rod 404 drives the filter assembly 3 to move downward, the side wall of the outer ring 301 scrapes the dust on the inner wall of the filter cartridge 5 downward to avoid the formation of dust residue on the inner wall of the filter cartridge 5. At the same time, the rotating motor 401 drives the spiral blade 403 to rotate in the opposite direction through the support shaft 402, so that negative pressure is generated above the spiral blade 403. The negative pressure when the spiral blade 403 rotates will discharge the dust shaken off the adsorption plate 203 and the filter layer 304 through the discharge pipe 103.

[0055] To summarize, after the filter assembly 3 moves up and approaches the adsorption assembly 2, the filter layer 304 is driven by the rotating motor 303 to knock against the adsorption plate 203, so that the dust on the filter layer 304 and the adsorption plate 203 falls off. Then, in the process of the filter assembly 3 moving downward, the outer ring 301 keeps the filter cartridge 5 clean, and the negative pressure caused by the reverse rotation of the spiral blade 403 causes the shaken-off dust to be discharged outward.
