Abstract
Description
Technical Field
[0001] This invention relates to the field of dust removal technology in coal preparation plants, specifically to a feeding isolation dust removal device. Background Technology
[0002] During the transfer and transportation of coal, a large amount of dust is inevitably generated due to impact, falling, vibration and other reasons. Therefore, adopting a reasonable dust removal system plays an important role in reducing dust generation and improving the working environment.
[0003] Currently, the two main dust removal methods commonly used in coal preparation plants are wet dust removal and dry dust removal. Wet dust removal has the advantages of low investment, strong adaptability, and high dust removal efficiency, but it is not very effective in reducing respirable dust. This is mainly because the water mist atomization degree is low and the droplets are too large, which cannot be effective against small particles of respirable dust. Although dry dust removal requires a large investment and occupies a large space, it is very effective in removing small particles of respirable dust. The dry fog dust suppression technology, which is gradually being widely used, has a better atomization effect and can effectively reduce the concentration of respirable dust. At present, due to the lack of effective dust removal devices and many deficiencies in the design of existing dust removal systems, most coal preparation plants in my country have serious dust emissions that exceed the standards. Severe dust pollution not only poses safety hazards to the plant's production, but also endangers the health of on-site workers, leading to occupational diseases such as pneumoconiosis. It can also reduce the insulation level of electrical equipment, accelerate equipment wear, and even cause major accidents such as dust explosions, affecting the safe and civilized production of the plant.
[0004] However, the main source of dust in existing coal preparation plants is generated during the operation of screening machines. The collision and friction between coal blocks and between coal blocks and screens on the screening machine will generate a lot of dust. The dust removal device at the feeding end of the screening machine has poor sealing, and dust is easy to overflow. Although dry fog dust suppression has a good dust removal effect, it is costly and not suitable for large-scale use. Summary of the Invention

[0021] 2. This invention employs a combination of an exhaust pipe, a discharge column, and an anode dust collection plate. It utilizes the working principle of centrifugal separation pretreatment followed by electrostatic adsorption for deep purification, with the anode dust collection plate locking in fine particles. This overcomes the shortcomings of existing technologies, such as dust easily escaping and the potential for secondary pollution, thereby achieving the technical effect of no dust overflow throughout the process and a high rate of compliance with environmental emission standards.
[0022] 3. This invention employs a combination of a support pipe, a cleaning air pump, an air collection pipe, and an air outlet.

[0037] 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 some embodiments of the present invention, and not all 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.
[0038] An embodiment of the present invention discloses a feeding isolation and dust removal device, such as... Figure 1-7 As shown, it includes: a dust collection assembly 100, which is mounted on a screening machine. The dust collection assembly 100 includes a dust collection box 110 located above the screening machine. Baffles 120 are fixedly connected to both sides of the dust collection box 110. A cross-flow fan 130 is fixedly installed inside the dust collection box 110. An opening is provided on the inner wall of the dust collection box 110. A dust collection air pump 140 is fixedly connected to the outer wall of the dust collection box 110. The air inlet of the dust collection air pump 140 is connected to the cross-flow fan 130. The top of the dust collection box 110 is an open structure.
[0039] Furthermore, the dust collection box 110 covers the top of the screening machine, and the baffles 120 on both sides form a closed space to reduce dust overflow;
[0040] It should be noted that the dust collector 200 is located on the side of the dust collection assembly 100, and the side walls of the two baffles 120 are fixedly connected to the outer wall of the dust collector 200. The dust collector 200 has an air inlet slot 201 on the side facing the dust collection box 110.
[0041] It should be noted that the control box 300 is fixedly connected to the top of the dust collector 200 at its bottom. The motor 400 is fixedly connected to the inner wall of the control box 300. A bevel gear 401 is fixedly connected to the output end of the motor 400 at its side. A bevel gear ring 402 is meshed with the bottom of the bevel gear 401.
[0042] In addition, an exhaust pipe 500 is installed inside the dust collector 200. The top of the exhaust pipe 500 passes through the top wall of the dust collector 200 and is fixedly inserted into the conical tooth ring 402. A spiral blade 501 is fixedly connected to the outer wall of the exhaust pipe 500.
[0043] Specifically, multiple diversion plates 150 are fixedly connected to the top wall of the dust collection box 110. The top wall of the uppermost diversion plate 150 is tightly connected to the inner wall of the dust collection box 110, and the width of the diversion plate 150 is the same as the length of the inner wall of the dust collection box 110.
[0044] Furthermore, an overflow prevention plate 160 is fixedly connected to the side wall of the dust collector 200, and the overflow prevention plate 160 is located above the diversion plate 150, thus preventing the airflow from escaping upward.
[0045] It should be noted that an airflow velocity sensor 170 and a dust concentration sensor 180 are fixedly installed on the side of the dust collection box 200 facing the dust collection assembly 100. The airflow velocity sensor 170 is located below the overflow plate 160, and the dust concentration sensor 180 is located below the air inlet slot 201.
[0046] Furthermore, the airflow velocity sensor 170 monitors the airflow velocity outside the dust collection box 200 in real time, and the dust concentration sensor 180 monitors the dust concentration below the air inlet sump 201. The data is synchronously transmitted to the control box 300. If the dust concentration is too high, it indicates that the dust removal efficiency is insufficient. The control box 300 automatically or manually adjusts the speed of the motor 400 to increase the rotation speed of the spiral blades 501 and enhance the centrifugal separation effect. At the same time, it can increase the power of the dust collection pump 140 to increase the adsorption airflow intensity. If the airflow velocity is too fast or too slow, the speed of the cross-flow fan 130 is adjusted to optimize the airflow delivery efficiency and ensure that the dust can be smoothly guided and fully separated.
[0047] It should be noted that a discharge pipe 202 is fixedly connected to the bottom of the dust collector 200, and an electric control valve is fixedly installed on the discharge pipe 202. Support feet 203 are symmetrically fixedly connected to the bottom of the dust collector 200.
[0048] It should be noted that the control box 300 has an air vent 301 on the top and multiple control buttons 302 are fixedly installed on the top wall of the control box 300.
[0049] The working principle of the above technical solution is as follows: During the use of this invention, after the device is installed, the dust collection box 110 is placed above the screening machine. The baffle 120, the diversion plate 150, and the overflow plate 160 form a closed isolation space to prevent dust from spreading to the external environment. The motor 400, dust collection air pump 140, and cross-flow fan 130 in the control box 300 are in standby mode. The airflow speed sensor 170 and the dust concentration sensor 180 are started for preheating and real-time monitoring of initial environmental data. The electric control valve of the discharge pipe 202 at the bottom of the dust collection box 200 remains closed. The support foot 203 firmly supports the entire device to ensure the stability during operation. The screening machine starts feeding and screening operations. The generated dust spreads to the surroundings under the impact of screening. The dust collection air pump 140 and the cross-flow fan 130 are started simultaneously. The cross-flow fan 130 is in the dust collection box 110. A negative pressure environment is formed inside, and an adsorption airflow is generated through the opening in the inner wall of the dust collection box 110. The diffused dust is captured by the negative pressure airflow and, constrained by the closed space of the dust collection box 110, cannot escape to the outside and is concentrated in the inner area of the dust collection box 110. Multiple guide plates 150 inside the dust collection box 110 play a guiding role. Because the width of the guide plate 150 is the same as the length of the inner wall of the dust collection box 110, and the uppermost guide plate 150 is tightly connected to the inner wall of the dust collection box 110, the dust-laden airflow is directed towards the dust removal box 200. The overflow plate 160 is located above the guide plate 150, blocking the airflow from escaping upward and forcing the dust-laden airflow to flow along the channel of the guide plate 150 to the air inlet slot 201 of the dust removal box 200. Under the continuous adsorption force of the dust collection air pump 140 and the guiding effect of the guide plate 150, the dust-laden airflow smoothly enters the interior of the dust removal box 200 through the air inlet slot 201.
[0050] During use, the motor 400 inside the control box 300 starts, and its output drives the bevel gear 401 to rotate. The bevel gear 401 meshes with the bevel gear ring 402, causing the bevel gear ring 402 to rotate synchronously. The top of the air outlet pipe 500 is fixedly inserted into the bevel gear ring 402 and rotates together with the bevel gear ring 402, thereby driving the spiral blades 501 fixedly connected to the outer wall to rotate at high speed. The dust-laden airflow entering the dust collector 200 comes into contact with the high-speed rotating spiral blades 501. The spiral blades 501 generate strong centrifugal force, throwing the denser dust particles in the airflow toward the inner wall of the dust collector 200. After the dust particles collide with the inner wall of the dust collector 200, they lose kinetic energy and fall vertically down the inner wall to the bottom of the dust collector 200, thus achieving the separation of dust and airflow. When dust accumulates to a certain amount at the bottom of the dust collector 200, the electric control valve on the discharge pipe 202 is opened manually via the control key 302 on the control box 300 or by sensor linkage control. The accumulated dust is discharged through the discharge pipe 202 to the designated collection container under the action of gravity, completing the centralized collection and treatment of dust. After the dust is discharged, the electric control valve is closed to prevent subsequent airflow from leaking from the discharge pipe 202 and to ensure the stability of airflow in the dust collector 200. The purified airflow after centrifugal separation by the spiral blades 501 does not contain a large number of dust particles and flows upward into the interior of the exhaust pipe 500. The airflow is transported upward along the exhaust pipe 500, and finally the purified airflow is discharged from the exhaust port 301 at the top of the control box 300, completing the entire dust removal process.
[0051] This invention employs a combination of a dust collection box 110, a baffle 120, a cross-flow fan 130, a dust collection air pump 140, a diversion plate 150, and an overflow prevention plate 160. By utilizing the negative pressure created by the cross-flow fan 130 and the dust collection air pump 140 to capture dust, and combining this with the working principle of the diversion plate 150 to guide the airflow in a directional manner, this invention overcomes the shortcomings of existing technologies, such as incomplete dust removal and easy dust overflow, thereby achieving the technical effects of efficient dust capture, no dust diffusion, and high dust removal coverage.
[0052] This invention employs a combination of an airflow velocity sensor 170 and a dust concentration sensor 180. By utilizing a dust collection box 110, a baffle 120, and an overflow prevention plate 160 to construct a semi-enclosed space to prevent dust from overflowing, the airflow velocity sensor 170 and the dust concentration sensor 180 monitor the operating conditions in real time and provide feedback to adjust the equipment parameters. This overcomes the shortcomings of existing technologies, such as poor environmental performance and inability to adapt to different dust concentration scenarios, thereby achieving the technical effect of dynamically optimizing operating parameters and adapting to various screening and feeding conditions.
[0053] This invention employs a combination of a dust collector 200, a control box 300, a motor 400, and an exhaust pipe 500. The exhaust pipe 500 and the rotating spiral blades 501 are used to centrifugally separate dust. An electrically controlled valve controls dust recovery, and the control box 300 simplifies the operation process. This overcomes the shortcomings of existing technologies, such as loose equipment structure and cumbersome operation and maintenance, thereby achieving the technical effects of strong overall equipment stability, small space occupation, convenient dust recovery, and low maintenance cost.
[0054] In a specific embodiment: a dust removal component 600 is provided inside the exhaust pipe 500. The dust removal component 600 includes two fixed rods 610 fixedly connected to the inner wall of the exhaust pipe 500. A discharge column 620 and a plurality of anode dust collection plates 630 are fixedly installed on the fixed rods 610, and the anode dust collection plates 630 are arranged on both sides of the discharge column 620.
[0055] The working principle of the above technical solution is as follows: During the use of this invention, the airflow after centrifugal separation by the spiral blades 501 may still contain a small amount of fine dust. It enters the outlet pipe 500 upwards and flows through the dust removal component 600 area. The fixing rod 610 stably supports the discharge column 620 and the anode dust collection plate 630 on the inner wall of the outlet pipe 500. After the discharge column 620 is energized, it releases high voltage static electricity, forming a strong electric field with the anode dust collection plates 630 on both sides. The fine dust particles in the airflow are ionized and charged in the strong electric field. Under the action of the electric field force, they move towards the anode dust collection plate 630 with opposite polarity and are finally adsorbed on the surface of the anode dust collection plate 630, realizing the deep purification of the fine dust remaining after centrifugal separation. The clean airflow after secondary purification by electrostatic adsorption continues to flow upwards along the outlet pipe 500 and is finally discharged from the outlet 301 of the control box 300, which more thoroughly purifies the fine dust and solves the problem of incomplete removal of small-diameter dust by single centrifugal separation.
[0056] This invention employs a combination of an exhaust pipe 500, a discharge column 620, and an anode dust collection plate 630. It utilizes the working principle of centrifugal separation pretreatment followed by electrostatic adsorption for deep purification, with the anode dust collection plate 630 locking in fine particles. This overcomes the shortcomings of existing technologies, such as dust easily escaping and the potential for secondary pollution, thereby achieving the technical effect of no dust overflow throughout the process and a high rate of compliance with environmental emission standards.
[0057] In one specific embodiment: a cleaning component 700 is provided inside the dust collection box 200. The cleaning component 700 includes a cleaning air pump 720 and an air collection pipe 730. The bottom of the cleaning air pump 720 is fixedly installed inside the control box 300. A support pipe 710 is fixedly connected to the air inlet end of the cleaning air pump 720. The bottom of the support pipe 710 is in contact with the top of the air outlet pipe 500. The top wall of the air collection pipe 730 is fixedly connected to the top surface inside the dust collection box 200. An air supply pipe 750 is fixedly connected to the air outlet end of the support pipe 710. The bottom end of the air supply pipe 750 is connected to the air collection pipe 730 through the top of the dust collection box 200. Multiple air outlet holes 740 are opened on the outer wall of the air collection pipe 730.
[0058] It should be noted that the gas collecting pipe 730 is sleeved outside the gas outlet pipe 500, and the gas outlet 740 is arranged around the outer wall of the gas collecting pipe 730, and each gas outlet 740 is set as an inclined structure.
[0059] It should be noted that the inner diameter of the support tube 710 is set to half the inner diameter of the air outlet tube 500. During the operation of the air outlet tube 500, the support tube 710 always covers the side above the air outlet tube 500.
[0060] The working principle of the above technical solution is as follows: During use, the clean airflow purified by electrostatic adsorption in the outlet pipe 500 flows upward to the top area. After the cleaning air pump 720 is started, the clean airflow is drawn through the support pipe 710. The support pipe 710 covers the upper side of the outlet pipe 500 to ensure stable airflow acquisition. Then, the airflow is delivered to the collection pipe 730 in the dust collector box 200 through the air delivery pipe 750. The inner diameter of the support pipe 710 is half that of the outlet pipe 500, which ensures sufficient pressure of the clean airflow without affecting the normal exhaust of the outlet pipe 500. The 730 is set outside the air outlet pipe 500, and its outer wall is surrounded by inclined air outlet holes 740 to form an annular jet area. Clean airflow is ejected obliquely from the air outlet holes 740 to form a directional airflow jet. The inclined air outlet holes 740 make the airflow directional, impacting the inner wall of the dust collector 200 and blowing off the attached dust. The dust blown off by the airflow falls to the bottom of the dust collector 200 under the action of gravity and gathers with the dust that was previously separated by centrifugation. The clean airflow itself is purified clean gas, which will not introduce new pollutants and will not affect the dust removal process inside the dust collector 200.
[0061] This invention employs a combination of a support pipe 710, a cleaning air pump 720, an air collecting pipe 730, and an air outlet 740. It utilizes the working principle of air collecting pipe 730 being sleeved outside air outlet pipe 500 and air being sprayed through inclined air outlets 740 to remove dust accumulated on the inner wall of dust collection box 200. This overcomes the shortcomings of existing technologies, such as limited cleaning range and difficulty in removing localized dust accumulation, thereby achieving comprehensive cleaning and maintaining the high-efficiency dust removal performance of the equipment.
