Description

Technical Field

[0001] The invention belongs to the technical field of dust processing equipment, in particular to a graphite sheet dust processing device. Background Art

[0002] Graphite tableting is the process of pressing graphite raw material powder into flakes or rings through a tablet press. The mechanical strength and electrical conductivity of graphite materials can be effectively enhanced by tableting. In the tableting process, the generation of dust is inevitable. If the dust is not handled, it will not only pollute the working environment, but also may cause harm to the health of operators.

[0003] In order to reduce the pollution of dust to the working environment during the graphite tableting process, graphite tableting machines are usually equipped with dust removal equipment to collect and reduce the content of graphite dust in the air. In actual operation, since the graphite dust is in a sealed state during the tableting process, the dust is mainly diffused to the outside from the tablet press inlet, tablet press outlet and other positions. The former is because when the graphite raw material is fed, the powdered graphite raw material will diffuse to the outside through the gap between the ton bag and the tableting inlet during movement, and the latter is because there is loosely adhered powder on the flake or ring graphite after tableting. When the powder is affected by the airflow, it will cause the powder to diffuse to the outside with the airflow. Therefore, dust control at the inlet and outlet of the tablet press can effectively reduce the probability of graphite dust dispersion and control graphite dust from the source.

[0004] In order to control graphite powder in the related technology, dust collectors, dust removers and other equipment are usually used to perform dust reduction and dust removal operations on the air. Among them, bag-type dust collectors, cartridge dust collectors and other equipment can effectively utilize the flow of air to concentrate and filter the dispersed dust, thereby achieving dust control. However, this type of equipment usually requires cleaning of the filter bags and filter cartridges, which not only makes the equipment too troublesome to use, but also easily causes secondary pollution during cleaning.

[0005] A graphite processing dust treatment device is disclosed in the related technology, and its application number is CN2024102521990. This scheme vibrates and shakes off the dust in the filter bag according to the degree of dust accumulation, thereby avoiding energy waste. The vibration shaking can comprehensively clean the filter bag and avoid the accumulation of dust in dead corners. However, in actual application, the concentrated dust still needs to be removed, and the problem of secondary pollution still exists.

The fluidity of water is relatively strong, so the air outlet of the dispersion pipe can contact with both water and collected impurities, thereby enhancing the preliminary interception effect of dust in the airflow. On the other hand, the airflow impacts downward first and then moves upward. Combined with the diversion effect of the dispersion pipe on the airflow and the dispersion effect of the dust removal chamber volume on the airflow, the rate of airflow flowing between the adsorption sheets can be effectively reduced, thereby enhancing the sedimentation and interception of dust in the airflow.

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] like Figures 1 to 12 As shown, a graphite sheet dust treatment device according to the present invention comprises a housing 1, a slag box 11 and an adsorption dust removal mechanism;

[0043] The housing 1 is provided with an air inlet passage 12, a dust removal chamber 13 and an air outlet passage 14 which are connected in sequence. The air inlet passage 12 is externally connected to a fan for extracting dusty air. A slag box 11 is installed at the bottom of the housing 1, and the slag box 11 extends into the dust removal chamber 13.

[0044] The adsorption dust removal mechanism is installed in the dust removal chamber 13, and is used to reduce dust on the airflow. The adsorption dust removal mechanism includes an adsorption sheet 2, an atomizing nozzle 23, a driving rod 25, and a frame plate 26;

[0045] A plurality of the adsorption sheets 2 are installed in parallel in the dust removal chamber 13, and an air flow channel is formed between two adjacent adsorption sheets 2;

[0046] A driving groove 24 is provided in the dust removal chamber 13, and a driving rod 25 is rotatably installed in the driving groove 24. The driving rod 25 is externally connected to a driving motor, and a reciprocating spiral groove is provided on the driving rod 25.

[0047] A frame plate 26 is installed in the dust removal chamber 13. The frame plate 26 is a frame-type structure. The plurality of adsorption sheets 2 are slidably connected to the frame plate 26. The frame plate 26 extends into the driving groove 24. The frame plate 26 is spirally driven with the driving rod 25 through a reciprocating thread groove.

[0048] An atomizing nozzle 23 is installed in the dust removal chamber 13 . The atomizing nozzle 23 is externally connected to a water supply pipeline. The atomizing nozzle 23 is used to spray water mist into the dust removal chamber 13 .

[0049] When managing dust in the environment where graphite tablets are located, a fan is used to extract air, wherein the fan is installed at a position corresponding to the inlet and outlet of the tablet press. The airflow is extracted to entrain the dust, and then the dust is extracted into the dust treatment device, where the dust is adsorbed and agglomerated by the adsorption dust removal mechanism, thereby purifying the air.

[0050] Specifically, during the tablet pressing operation, the fan extracts air from dust sources such as the tablet press inlet and outlet. It should be noted that the fan described in the present invention is an air extraction device. In actual application, an axial flow fan, a tangential flow fan, etc., or an air flow extraction device such as an air compressor can be used to transport dust-laden air to the inside of the air inlet channel 12. Under the action of pressure, the air flow flows along the air inlet channel 12 to the dust removal chamber 13. At the same time, when the fan is started, the atomizing nozzle 23 in the dust removal chamber 13 is started, and the atomizing nozzle 23 is connected to an external water supply device through a pipeline. When the atomizing nozzle 23 is started, Water is sprayed in the dust removal chamber 13 in the form of water mist. Under the action of gravity, the water mist gradually moves to the bottom of the dust removal chamber 13, and the dust-containing air entering the dust removal chamber 13 gradually flows to the air outlet channel 14 at the top of the shell 1 under the action of air pressure. During the flow process, the flow directions of the water mist and the air are opposite, so that the water mist and the dust-containing air are mixed, so that the small water droplets come into contact with the graphite dust. Under the viscosity of the water, the graphite dust is adsorbed to each other to form particulate impurities. At the same time, since the dust removal chamber 13 is fixedly installed with evenly distributed adsorption plates, the water mist and the air pass through the adsorption plates. The airflow channel formed by the gap passes through, and the existence of the adsorption plate provides an attachment surface for water mist, dust, and particulate impurities, so that water mist, dust, and particulate impurities are fixed on the adsorption plate, thereby achieving the adsorption and filtering effect of the airflow, and the driving rod 25 installed in the driving groove 24 is driven by an external driving motor to rotate at a uniform speed. Since a reciprocating spiral groove is provided on the driving rod 25, and a frame plate 26 is installed on the driving rod 25, the frame plate 26 is connected to the driving rod 25 through the reciprocating spiral groove. Therefore, the frame plate 26 performs a linear reciprocating motion in the dust removal chamber 13, and because the frame The plate 26 and multiple adsorption sheets 2 are all slidably installed, so during the linear reciprocating motion of the frame plate 26, the frame plate 26 will scrape the dust and granular impurities adsorbed on the adsorption sheets 2. As the frame plate 26 continues to move, the dust, water droplets and granular impurities gather and agglomerate into blocks or large particles, and under the action of gravity, they fall downward along the gaps in the adsorption sheets 2, and extend to the slag box 11 in the dust removal chamber 13 to receive them. During long-term operation, the staff manually pulls out the slag box 11 to clean the wet, block or large granular impurities in the slag box 11.

[0051] It should be noted that although graphite dust is a hydrophobic material and does not absorb water itself, when water mist adheres to the graphite dust, the tension and viscosity of the water will cause the graphite dust to aggregate with each other, thereby causing small particles of dust to gather into clumps.

[0052] The present invention provides an adsorption dust removal component. On the one hand, it uses water mist to settle the dust in the air and remove the dust and impurities in the air. On the other hand, it provides an adhesion surface for the water mist, dust and impurities by providing an adsorption sheet 2, thereby effectively enhancing the interception effect of dust and impurities. At the same time, because the intercepted dust and impurities are moistened by the water mist, when the frame plate 26 scrapes, they are gathered into block or granular impurities under the scraping action, and then when cleaning them, the probability of secondary pollution caused by the disturbance of airflow to the dust is effectively reduced.

[0053] As a preferred embodiment of the present invention, the adsorption sheets 2 are all designed in a wave shape in the vertical direction, and the gap width between two adjacent adsorption sheets 2 is smaller than the wave amplitude width of the adsorption sheets 2 .

[0054] After the airflow enters the dust removal chamber 13 from the air inlet channel 12, the airflow moves upward along the gap of the adsorption sheet 2. Since the adsorption sheet 2 is wavy and the gap of the adsorption sheet 2 is smaller than the amplitude width of the wave shape of the adsorption sheet 2, the airflow cannot have a linear trajectory during its upward movement. On the one hand, the change in the airflow trajectory is used to increase the movement distance of the airflow in the dust removal chamber 13, thereby improving the combination efficiency of the dust and water mist in the airflow. On the other hand, the change in the airflow trajectory is used to improve the contact efficiency between the airflow and the adsorption sheet 2, thereby enhancing the dust interception effect of the adsorption sheet 2 with the cooperation of the water mist, thereby enhancing the air purification effect.

[0055] As a preferred embodiment of the present invention, the adsorption sheet 2 is composed of a steel sheet 21 and a water-fixing layer 22. The water-fixing layer 22 is fixedly installed on both sides of the steel sheet 21. The water-fixing layer 22 is made of absorbent fiber cloth.

[0056] The adsorption sheet 2 is made of a water-solidifying layer 22 made of absorbent fiber cloth and a steel sheet 21, wherein the steel sheet 21 provides a supporting force so that the shape of the adsorption sheet 2 is not easily changed, and the water-solidifying layer 22 made of the absorbent fiber cloth can fix the water mist so that the water droplets gathered by the water mist can be adsorbed in the water-solidifying layer 22. When the airflow passes through the gap of the adsorption sheet 2, on the one hand, the water mist in the gap of the adsorption sheet 2 converges with the dust in the airflow to promote the dust sedimentation. On the other hand, after absorbing the water mist, the water-solidifying layer 22 can also intercept the dust in the airflow under the action of the viscosity of water, thereby effectively enhancing the interception effect of the dust in the airflow. At the same time, the fiber cloth has a large surface friction, which can enhance the adhesion strength of dust and impurities.

[0057] As a preferred embodiment of the present invention, a rack pipe 3 is fixedly installed at the bottom of the multiple adsorption sheets 2. The rack pipe 3 is used to connect the multiple adsorption sheets 2 as a whole. The rack pipe 3 is hollow, and the adsorption sheets 2 extend into the rack pipe 3. A water level sensor is installed inside the rack pipe 3, and the water level sensor is electrically connected to the atomizing nozzle 23.

[0058] In actual use, the atomizing nozzle 23 continuously sprays water mist into the dust removal chamber 13, and the water mist is adsorbed on the adsorption sheet 2, so that the adsorption sheet 2 and the dust are in a wet state. When the water mist spraying efficiency is high, when there is more water gathered on the adsorption sheet 2, the water droplets flow downward under the action of gravity and enter the inner cavity of the rack pipe 3. When the airflow flows, part of the water mist will be lost. At this time, the water in the rack will diffuse to the adsorption sheet 2 under the capillary action of the fiber gap, thereby reducing the probability of the surface of the adsorption sheet 2 drying when used for a long time, thereby making The adsorption sheet 2 can continuously intercept the dust in the airflow. At the same time, the water level sensor installed in the pipe rack 3 can also monitor the water level in the pipe rack in real time. When the water level in the pipe rack 3 is low, the power of the atomizing nozzle 23 spraying water mist is increased by controlling the preset degree. When the water level in the pipe rack is high, the efficiency of the atomizing nozzle 23 spraying water mist is reduced, which can prevent excessive water mist from condensing into water droplets, causing the sewage to converge too quickly in the slag box 11, and make the water vapor concentration entrained in the airflow after passing through the dust removal chamber 13 relatively constant.

[0059] As a preferred embodiment of the present invention, it also includes a drainage primary screening component, which is connected to the air inlet channel 12 and is used to guide the air flow direction. The drainage primary screening component includes a drainage tube 4 and a dispersion tube 41;

[0060] The drainage pipe 4 is fixedly installed in the air inlet channel 12, and the drainage pipe 4 extends to the bottom of the dust removal chamber 13. The dispersion pipes 41 are evenly dispersed in the dust removal chamber 13. The dispersion pipes 41 are conductively connected with the drainage pipe 4, and the dispersion pipes 41 are opened toward one side of the slag box 11.

[0061] In the process of dust reduction by water mist, since graphite dust itself does not have water absorption, as the water mist gathers into water droplets, the excess water droplets eventually drip into the slag box 11. When the airflow enters the air inlet channel 12 through the fan, the airflow enters the dispersion pipe 41 from the drainage pipe 4, and flows toward the slag box 11 from the bottom opening of the dispersion pipe 41. On the one hand, the airflow impacts the impurities and water in the slag box 11, causing the impurities and water to contact with the airflow, thereby preliminarily intercepting the impurities and dust in the airflow, and due to the impact force of the airflow, it will make The dust in the slag box 11 forms a depression corresponding to the opening of the dispersion tube 41, and the fluidity of water is relatively strong, so the gas discharged from the dispersion tube 41 can come into contact with both water and collected impurities, thereby enhancing the initial interception effect of dust in the airflow. On the other hand, the airflow first impacts downward and then moves upward. Combined with the diversion effect of the dispersion tube 41 on the airflow and the dispersion effect of the volume of the dust removal chamber 13 on the airflow, the flow rate of the airflow between the adsorption sheets 2 can be effectively reduced, thereby enhancing the sedimentation and interception effect of the dust in the airflow.

[0062] As a preferred embodiment of the present invention, the drainage primary screening assembly also includes a coarse filter 5, which is fixedly installed in the dust removal chamber 13, and the coarse filter 5 is located above the drainage pipe 4. The bottom of the frame plate 26 is equipped with evenly distributed toggle teeth 51, and the bottom end of the toggle teeth 51 is slidably connected to the surface of the coarse filter 5, and the toggle teeth 51 are all made of spring steel sheets 21.

[0063] As the frame 26 continues to reciprocate, dust and water gather into large particles of impurities and fall downward and are intercepted by the coarse filter 5. The airflow ejected from the dispersion pipe 41 moves toward the coarse filter 5 after contacting the mixture of water and dust in the slag box 11, and under the action of air pressure, moves upward through the gaps of the coarse filter 5 and the gaps of large particles of impurities, thereby intercepting the dust in the airflow again. At the same time, as the frame 26 continues to move, the toggle teeth 51 installed at the bottom of the frame 26 move synchronously, and the toggle teeth 51 toggle the large particles of impurities on the surface of the coarse filter 5. On the one hand, impurities with smaller particle sizes fall into the slag box 11, and on the other hand, the size of the gaps between large particles of impurities is changed, thereby changing the path of the airflow through the gaps of large particles of impurities, thereby enhancing the interception effect of dust in the airflow.

[0064] As a preferred embodiment of the present invention, a movable groove 52 is provided at the bottom of the frame plate 26, a connecting plate 53 is slidably installed in the movable groove 52, the shifting teeth 51 are fixedly installed on the connecting plate 53, a through groove 54 is provided on the frame plate 26, the through groove 54 is perpendicular to the movable groove 52, a push rod 55 is slidably installed in the through groove 54, the push rod 55 is Z-shaped, a limiting groove 56 is provided on the connecting plate 53, and the limiting groove 56 is slidably connected to the middle part of the push rod 55.

[0065] A plurality of shifting teeth 51 are fixed on the connecting plate 53, and the connecting plate 53 is slidably installed in the moving groove 52. With the continuous movement of the frame plate 26, when the frame plate 26 contacts one side of the dust removal chamber 13, the push rod 55 is squeezed, so that the push rod 55 slides in the through groove 54. Since the push rod 55 has a Z-shaped structure, and the connecting plate 53 is connected to the middle part of the push rod 55 through the limiting groove 56, when the push rod 55 moves, the connecting plate 53 is prompted to move in the moving groove 52. In the process of the connecting plate 53 continuing to reciprocate following the frame plate 26, the sliding of the connecting plate 53 will change the action position of the shifting teeth 51 on the coarse filter 5, thereby enhancing the uniformity of shifting large particles of impurities in the coarse filter 5.

[0066] As a preferred embodiment of the present invention, a push plate 57 is fixedly installed on the multiple toggle teeth 51, and a limited pipe 58 is fixedly installed at both ends of the coarse filter screen 5. The push plate 57 is used to cooperate with the limited pipe 58 to transport the dust exceeding the height of the limited pipe 58 to the slag box 11.

[0067] As a preferred embodiment of the present invention, an elastic sheet 6 is fixedly installed inside the limiting tube 58, and a support sheet 61 is fixedly installed on one side of the limiting tube 58 by bolts. The elastic sheet 6 extends onto the support sheet 61. In the initial state, the support sheet 61 is arranged obliquely, and the elastic sheet 6 blocks the limiting tube 58.

[0068] The existence of the limiting tube 58 can push the large particles of impurities at a high place and make them fall into the limiting tube 58 when the toggle tooth 51 moves with the frame plate 26, and then fall into the slag box 11 through the limiting tube 58. The support sheet 61 and the elastic sheet 6 installed in the limiting tube 58 can block the limiting tube 58. As the weight of the large particles of impurities in the limiting tube 58 gradually increases, the support sheet 61 and the elastic sheet 6 gradually bend and deform under the action of pressure, so that the initially closed limiting tube 58 is reopened, so that the large particles of impurities fall into the slag box 11. The existence of the large particles of impurities in the limiting tube 58 and the elastic sheet 6 can block the limiting tube 58 to prevent the airflow from flowing directly upward from the limiting tube 58.

[0069] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
