Description

Technical Field

[0002] As a common industrial equipment, gravity separator is widely used in chemical, metallurgical, pharmaceutical and other industries to separate solid particles from mixed gases. The equipment achieves separation by utilizing the density difference between different substances, thereby improving production efficiency and product quality. Traditional gravity separators usually use simple physical methods such as sedimentation and centrifugation. Although these methods are simple to operate and low in cost, their separation effect is often unsatisfactory when dealing with gases containing a lot of dust and impurities.

[0003] In order to meet the above challenges, existing technical solutions mainly focus on improving the structural design of the separation device. For example, some common methods include adding multi-stage filters in the separation tank to enhance the separation effect by changing the gas flow rate; or adding a pretreatment device outside the separation tank to pre-remove some large particle impurities and reduce the burden on the main separator. In addition, there are methods to promote particle sedimentation by adding a vibration device, and designs to optimize the gas flow distribution by changing the gas inlet position. These methods have improved the separation efficiency to a certain extent, but there are still some shortcomings.

[0004] However, existing gravity separators still face the problem of poor dust removal when processing gases containing a large amount of dust and suspended matter.

[0020] The following is combined with Figure 1-9 This application is described in further detail.

[0021] The embodiment of the present application discloses a gravity separator with a dust removal structure.

[0022] Reference Figure 1 and Figure 2 A gravity separator with a dust removal structure comprises a separation tank 1, a first dust removal component 2 for removing dust from materials with a density greater than that of air in the gas entering the separation tank 1, and a second dust removal component 3 for removing dust from suspended matter in the air; The separation tank 1 is vertically arranged, and the first dust removal component 2 and the second dust removal component 3 are sequentially installed in the separation tank 1 from high to low. An air inlet pipe 11 is installed on the separation tank 1, one end of which is connected to the external gas, and the other end is located between the first dust removal component 2 and the second dust removal component 3 in the separation tank 1. A discharge port is provided at the top of the separation tank 1; The first dust removal component 2 is provided with a first cleaning component 4 for cleaning the first dust removal component 2. The second dust removal component 3 is provided with a second cleaning component 5 for cleaning the second dust removal component 3; When the gas to be dusted enters the separation tank 1 through the air inlet pipe 11, the substances with a density greater than that of air fall on the first dust removal component 2, and the remaining gas is dusted by the second dust removal component 3 and then discharged from the discharge port of the separation tank 1, thereby achieving the effect of dust removal for the gas to be dusted; at the same time, the first dust removal component 2 and the second dust removal component 3 are cleaned respectively by the first cleaning component 4 and the second cleaning component 5 to ensure the efficiency of dust removal.

[0023] Reference Figure 2 and Figure 3 In order to better remove dust from materials with a density greater than that of air, the first dust removal component 2 includes a conical sliding cone 21, the sliding cone 21 has its cone head facing upward and is arranged at the bottom of the separation tank 1. One end of the air inlet pipe 11 located in the separation tank 1 is connected to a vertical section 12, the vertical section 12 faces vertically downward, and the vertical section 12 is coaxial with the sliding cone 21; The gas to be dusted is ejected from the vertical section 12 and hits the sliding cone 21, so that particles with a density greater than that of air hit the sliding cone 21 and slide down from the conical surface of the sliding cone 21. The vertical jetting method of the vertical section 12 increases the speed of particles with a density greater than that of air, so as to prevent them from being blown up by the airflow and entering the second dust removal component 3.

[0024] Reference Figure 3 In order to further enhance the dust removal effect of the first dust removal assembly 2, a layer of artificial turf 22 is wrapped on the surface of the sliding cone 21, and the filaments on the artificial turf 22 are used to intercept the particles in the airflow.

[0025] Reference Figure 2 and Figure 3 In order to clean and collect particles on the surface of the sliding cone 21, the first cleaning component 4 includes a scraper 41, one side of the scraper 41 is in contact with the surface of the sliding cone 21, and when the artificial turf 22 is laid, it is in contact with the artificial turf 22, and the scraper 41 is rotatably connected to the separation tank 1, and the rotation axis of the scraper 41 and the separation tank 1 coincides with the axis of the sliding cone 21; the bottom wall of the separation tank 1 is provided with an annular collection groove 13 concentric with the sliding cone 21; The scraper 41 is rotated to remove particles on the artificial turf 22 and cause the particles to fall into the collecting tank 13 .

[0026] Reference Figure 1 and Figure 2 In order to facilitate personnel to take out the particles in the collecting tank 13, a collecting drawer 14 is detachably installed at the bottom of the separation tank 1, and a plurality of drop holes connected to the collecting drawer 14 are opened at the bottom of the collecting tank 13; Reference Figure 3 In order to facilitate the particles in the collecting trough 13 to fall from the drop hole, the scraper 41 extends into the collecting trough 13.

[0027] Reference Figure 2 and Figure 3 In order to adjust the cleaning frequency of the scraper 41 according to the flow rate of the gas entering the separation tank 1, a gravity separator with a dust removal structure also includes a first driving assembly 6 for driving the scraper 41 to rotate, the first driving assembly 6 includes a first rotating shaft 61 and an impeller 62, the first rotating shaft 61 is coaxially rotatably connected to the vertical section 12, the impeller 62 is coaxially fixedly connected to the first rotating shaft 61 and is located in the vertical section 12, and one end of the first rotating shaft 61 close to the sliding cone 21 is fixed to the scraper 41; In this way, the air to be dusted in the vertical section 12 drives the impeller 62 to rotate, and the impeller 62 drives the first rotating shaft 61 to rotate while driving the scraper 41 to rotate. The impeller 62 changes the rotation speed according to the size of the air flow velocity in the vertical section 12, thereby changing the rotation speed of the scraper 41.

[0028] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6 In order to clean the particles suspended in the dust removal gas, the second dust removal component 3 includes a dust removal disc 31, which is horizontally mounted on the inner wall of the separation tank 1 and divides the separation tank 1 into upper and lower areas that are not connected to each other. The dust removal disc 31 is provided with a plurality of air inlet grooves 32 in the vertical direction on one side facing the sliding cone 21. The plurality of air inlet grooves 32 are evenly distributed along the circumference of the dust removal disc 31. The dust removal disc 31 is provided with a plurality of exhaust grooves 33 in the vertical direction on one side away from the sliding cone 21. One exhaust groove 33 is located between two exhaust grooves 32. A plurality of filter holes 34 connecting two adjacent exhaust grooves 33 are provided on the side wall of the air inlet groove 32. Thus, the gas ejected from the vertical section 12 collides with the sliding cone 21, moves upward, enters the air inlet groove 32, is filtered through the filter hole 34, and is discharged from the exhaust groove 33, thereby filtering the suspended matter in the gas to be removed.

[0029] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6In order to clean the surface of the filter hole 34 in the air inlet groove 32, the second cleaning assembly 5 includes a plurality of cleaning plates 51 and a plurality of connecting rods 52. A cleaning plate 51 is provided in one air inlet groove 32, and the side wall of the cleaning plate 51 abuts against the side wall of the air inlet groove 32. One end of a connecting rod 52 is fixed to a cleaning plate 51, and the other end passes through the dust removal disc 31 and extends to the top of the dust removal disc 31, and the connecting rod 52 is elastically slidably connected to the dust removal disc 31. When the connecting rod 52 is in a normal state, the cleaning plate 51 fits against the top wall of the air inlet groove 32. The first rotating shaft 61 coaxially passes through the dust removal disc 31 and extends to the top of the dust removal disc 31. The first rotating shaft 61 is located on the side wall above the dust removal disc 31. A first spiral groove 611 is provided along a spiral line with one turn. Both ends of the first spiral groove 611 are connected through a vertical first connecting groove 612, so that the first spiral groove 611 and the first connecting groove 612 form a spatial closed loop. A first sliding block 521 is provided at one end of the connecting rod 52 away from the cleaning plate 51. The first sliding block 521 can slide in the first spiral groove 611 and the first connecting groove 612. Therefore, when the first rotating shaft 61 rotates, the first slider slides in the first spiral groove 611, driving the connecting rod 52 to slide along the first spiral groove 611, driving the cleaning plate 51 to slide downward, for the filter hole 34 on the inner wall of the air inlet groove 32, when the first sliding block 521 slides to the first connecting groove 612, since the connecting rod 52 is elastically slidably connected to the dust removal disc 31, at this time, the first sliding block 521 returns to the initial state along the first connecting groove 612, so as to cyclically clean the filter hole 34, and at the same time, since the speed of the first rotating shaft 61 is affected by the air flow velocity in the vertical section 12, the cleaning frequency of the cleaning plate 51 can also change with the gas flow velocity entering the separation tank 1; At the same time, by providing multiple air inlet grooves 32 and multiple cleaning plates 51, when one cleaning plate 51 cleans a portion of the filter holes 34 blocked by an air inlet groove 32, the cleaning plate 51 in another air inlet groove 32 returns to its initial state. Compared with a single air inlet groove 32, it can ensure that the number of filter holes 34 in normal use will not change significantly, and will not cause a large change in the air pressure in the separation tank 1, causing air flow turbulence, forcibly pushing the debris particles at the filter holes 34 through the filter holes 34, and affecting the filtration quality.

[0030] Reference Figure 6At the same time, in order to further clean the filter holes 34, the second cleaning component 5 also includes a vibration plate 53 and an elastic member 54. A vibration plate 53 is provided in each exhaust groove 33, and the vibration plate 53 is connected to the bottom wall of the exhaust groove 33 through the elastic member 54. In the present application, the elastic member 54 is a spring. When the cleaning plate 51 cleans the air inlet groove 32, the air flow velocity on both sides of the exhaust groove 33 changes, driving the vibration plate 53 to swing, and the vibration plate 53 vibrates and cleans the filter holes 34 by slapping both sides of the exhaust groove 33.

[0031] Reference Figure 5 In order to reduce the particles scraped off the side wall of the air inlet groove 32 by the cleaning plate 51 and re-entering the air inlet groove 32 with the air flow, a guide groove 55 is provided at the bottom of the side wall of the air inlet groove 32 where the filter hole 34 is opened. The guide groove 55 is gradually inclined downward toward the center of the dust removal disc 31 in a direction parallel to the diameter of the dust removal disc 31; In this way, when the cleaning plate 51 scrapes the particles on the side wall of the air inlet groove 32 and drops them into the guide groove 55, they fall on the side close to the center of the dust removal disc 31 through the guide groove 55. Due to the conical shape of the sliding cone 21, the air flow rises along the side of the separation tank 1, so that the closer the dust removal disc 31 is to the center, the smaller the air flow velocity becomes, which makes it easier for particles in the guide groove 55 to fall.

[0032] Reference Figure 2 , Figure 7 , Figure 8 and Fig. 9 In order to further remove dust from particles in the air that are smaller than the filter hole 34 and dissolved in the liquid, a gravity separator with a dust removal structure also includes a third dust removal component 7, and the third dust removal component 7 includes a conical mounting plate 71, the mounting plate 71 is located above the dust removal disc 31, the cone head is upward, and the mounting plate 71 is coaxial with the first rotating shaft 61, and the mounting plate 71 is fixed to the inner wall of the separation tank 1 through a mounting ring 72, and the mounting plate 71 and the mounting ring 72 separate the separation tank 1 into upper and lower areas that are not connected to each other; A plurality of first air inlet channels 73 are provided on the mounting plate 71 in a direction parallel to the generatrix of the mounting plate 71. The first air inlet channels 73 connect the upper and lower areas of the mounting plate 71, and the plurality of first air inlet channels 73 are distributed circumferentially along the mounting plate 71. A second rotating shaft 74 is coaxially provided in the first air inlet channels 73. The second rotating shaft 74 is installed on the mounting plate 71, and an atomizing nozzle 75, a plurality of contact whiskers 76, and a water absorption cylinder 77 sleeved on the second rotating shaft 74 are sequentially provided on the second rotating shaft 74 from low to high. In the present application, the water absorption cylinder 77 is a sponge cylinder. A water storage tank 78 is fixed below the mounting plate 71. The water storage tank 78 is connected to each first air inlet channel 73 via a connecting pipe, and the connecting portion between the connecting pipe and the first air inlet channel 73 is located below the atomizing nozzle 75. Thus, the gas exhausted from the exhaust groove 33 enters the first air inlet channel 73, passes through the water mist sprayed by the atomizing nozzle 75 on the first rotating shaft 61, and the particles soluble in water dissolve in the small water droplets in the airflow, and then contact with the contact whiskers 76. The contact whiskers 76 block the small water droplets in the airflow on the one hand, and block some particles in the airflow on the other hand. When the airflow passes through the water absorption cylinder 77, the water absorption cylinder 77 absorbs the water vapor in the airflow, and then the airflow is discharged from the first air inlet channel 73, and finally discharged from the air outlet of the separation tank 1; The water flow collected in the first air inlet channel 73 flows into the water storage tank 78 through the connecting pipe.

[0033] Reference Figure 3 , Figure 8 and Fig. 9 In order to increase the dust removal effect of the first dust removal assembly 2, a second water inlet channel 613 is provided inside the first rotating shaft 61, and a water outlet communicating with the second water inlet channel is provided on the peripheral wall of the first rotating shaft 61 located below the impeller 62; The water storage tank 78 is connected to the second water inlet channel 613, and a pressure control valve 614 is provided at the connection point between the water storage tank 78 and the second water inlet channel 613. When the water level in the water storage tank 78 exceeds a certain limit, the pressure control valve 614 connects the water storage tank 78 with the second water inlet channel 613. When the water level in the water storage tank 78 reaches a certain height, the pressure control valve 614 opens, and the water in the water storage tank 78 enters the second water inlet channel 613, and the water flows out from the water outlet to the surface of the sliding cone 21 or the artificial turf 22, thereby enhancing the adsorption force on the particles. At the same time, due to the existence of the pressure control valve 614, the pressure control valve 614 will not be activated until the water pressure plus the air pressure reaches a certain pressure, thereby ensuring that the airflow does not flow back from the second water inlet channel 613 to the bottom of the dust removal disc 31.

[0034] Reference Figure 8 and Fig. 9 In order to throw off the particles and water droplets attached to the contact whiskers 76 and squeeze the water absorption cylinder 77 to squeeze out the water in it, the second rotating shaft 74 coaxially rotates on the mounting plate 71. The second rotating shaft 74 is provided with a squeezing plate 79 between the contact whiskers 76 and the water absorption cylinder 77. The squeezing plate 79 slides elastically on the second rotating shaft 74 along the axis of the second rotating shaft 74. In normal state, the squeezing plate 79 tends to move toward the side away from the water absorption cylinder 77. A second spiral groove 731 is provided on the peripheral wall of the first air inlet channel 73 along a spiral line with one turn, and both ends of the second spiral groove 731 are connected through a second connecting groove 732 parallel to the axis of the second rotating shaft 74, so that the second spiral groove 731 and the second connecting groove 732 form a spatial closed loop, and a second sliding block 791 is provided on the extrusion plate 79, and the second sliding block 791 can slide in the second spiral groove 731 and the second connecting groove 732; The second rotating shaft 74 is connected to the water pipe supplying water to the atomizing nozzle 75 via a rotating joint; In this way, the contact whisker 76 is driven to rotate during the rotation of the second rotating shaft 74, and the attachments thereon are thrown off by centrifugal force. At the same time, the second rotating shaft 74 drives the extrusion plate 79 to rotate. Due to the presence of the second sliding block 791, the second spiral groove 731 and the second connecting groove 732, the extrusion plate 79 reciprocates along the axis of the second rotating shaft 74 during the rotation of the second rotating shaft 74, and squeezes out the water in the water absorption cylinder 77, thereby ensuring that the water absorption of the water absorption cylinder 77 is always at a high level.

[0035] Reference Figure 8 and Fig. 9 In order to control the rotation rate of the second rotating shaft 74 according to the flow rate of the airflow entering the separation tank 1, a gravity separator with a dust removal structure also includes a second driving assembly 8 for driving the second rotating shaft 74 to rotate, and the second driving assembly 8 includes a first bevel gear 81 and a bevel gear plate 82. Each second rotating shaft 74 extends below the mounting plate 71 and is coaxially fixed with a first bevel gear 81. The bevel gear plate 82 is coaxially rotatably connected to the separation tank 1 and is coaxial with the first rotating shaft 61. The bevel gear plate 82 and the first rotating shaft 61 are connected to each other through a connecting rod; The first rotating shaft 61 rotates while driving the bevel gear plate 82 to rotate. The bevel gear plate 82 drives the first bevel gear 81 to rotate, thereby driving the second rotating shaft 74 to rotate.

[0036] Reference Figure 8 and Fig. 9 In order to prevent the first air inlet channel 73 from being blocked by the water flow squeezed out by the water cylinder during the squeezing of the water absorption cylinder 77 by the squeezing disk 79, or the phenomenon that the airflow in the first air inlet channel 73 is diverted upward, in the present application, a first blocking disk 733 is provided at the air inlet of the first air inlet channel 73, and the peripheral wall of the first blocking disk 733 abuts against the peripheral wall of the first air inlet channel 73, and a second blocking disk 741 abutting against the first blocking disk 733 is fixed on the second rotating shaft 74, and the first blocking plate and the second blocking disk 741 are respectively provided with ventilation openings that can overlap; the bevel teeth on the bevel gear disk 82 are provided with a plurality of notches, and each section of the bevel teeth can drive the second rotating shaft 74 to rotate one circle; When the bevel gear plate 82 rotates, only a portion of the first bevel gear 81 engages with it and rotates therewith. During the rotation of the second rotating shaft 74, the second sealing plate 741 rotates therewith, and the vents on the second sealing plate 741 are misaligned with the vents on the first sealing plate 733, and the first air inlet channel 73 is closed. After the second rotating shaft 74 rotates one circle, the vents on the second sealing plate 741 overlap with the vents on the first sealing plate 733, and the first air inlet channel 73 is opened.
