Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gravity separators, in particular to a gravity separator with a dust removal structure. BACKGROUND

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

[0003] To address the above challenges, existing technical solutions mainly focus on improving the structural design of the separation device. For example, some common methods include adding multiple filter screens 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 remove some large particle impurities in advance, reducing the burden on the main separator. In addition, there are methods of adding vibration devices to promote particle sedimentation, and designs of changing the gas inlet position to optimize gas flow distribution. These methods have improved separation efficiency to some extent, but still have some shortcomings.

Especially after a long time of operation, the dust removal assembly is prone to dust accumulation, which leads to a decrease in separation effect and requires frequent shutdown for cleaning, increasing maintenance costs and the risk of production interruption.

[0042] The separation tank 1 is vertically arranged, the first dust removal assembly 2 and the second dust removal assembly 3 are sequentially arranged from top to bottom in the separation tank 1, the separation tank 1 is provided with an air inlet pipe 11, one end of which is connected to external gas, and the other end is located between the first dust removal assembly 2 and the second dust removal assembly 3 in the separation tank 1, and the separation tank 1 is provided with an outlet at the top end.

[0043] The first dust removal assembly 2 is provided with a first cleaning assembly 4 for cleaning the first dust removal assembly 2,

[0044] The second dust removal assembly 3 is provided with a second cleaning assembly 5 for cleaning the second dust removal assembly 3.

[0045] When the gas to be removed 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 assembly 2, and the remaining gas is removed by the second dust removal assembly 3 and then discharged from the outlet of the separation tank 1, so as to achieve the effect of removing the gas to be removed. At the same time, the first dust removal assembly 2 and the second dust removal assembly 3 are cleaned by the first cleaning assembly 4 and the second cleaning assembly 5 respectively, so as to ensure the efficiency of dust removal.

[0046] With reference to Figure 2 and Figure 3 , in order to better remove the substances with a density greater than that of air, the first dust removal assembly 2 comprises a conical sliding cone 21, the conical sliding cone 21 has a conical head facing upward and is arranged at the bottom of the separation tank 1, the vertical section 12 is connected to one end of the air inlet pipe 11 located in the separation tank 1, the vertical section 12 vertically faces downward, and the vertical section 12 is coaxial with the sliding cone 21.

[0047] The gas to be removed is sprayed from the vertical section 12 and hits the sliding cone 21, so that the 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, and the vertical spraying mode of the vertical section 12 increases the speed of the particles with a density greater than that of air, so that the particles are prevented from being blown up by the airflow and entering the second dust removal assembly 3.

[0048] With reference to Figure 3 , in order to further increase 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.

[0049] With reference to Figure 2 and Figure 3In order to clean and collect the particles on the surface of the slide cone 21, the first cleaning assembly 4 comprises a scraper 41, one side of which is tangent to the surface of the slide cone 21 and is tangent to the artificial turf 22 when the artificial turf 22 is laid, and the scraper 41 is rotationally connected to the separation tank 1, and the rotational axis of the scraper 41 and the separation tank 1 coincides with the axis of the slide cone 21; the bottom wall of the separation tank 1 is provided with an annular collecting groove 13 concentric with the slide cone 21;

[0050] The rotating scraper 41 is used to push the particles on the artificial turf 22 to fall into the collecting groove 13.

[0051] Referring to Figure 1 and Figure 2 , in order to facilitate personnel to take out the particles in the collecting groove 13, the bottom of the separation tank 1 is detachably provided with a collecting drawer 14, and the bottom of the collecting groove 13 is provided with a plurality of drop holes communicating with the collecting drawer 14;

[0052] Referring to Figure 3 , in order to facilitate the particles in the collecting groove 13 to drop from the drop holes, the scraper 41 extends into the collecting groove 13.

[0053] Referring to 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, the gravity separator with a dust removal structure further comprises a first driving assembly 6 for driving the scraper 41 to rotate, the first driving assembly 6 comprising a first rotating shaft 61 and an impeller 62, the first rotating shaft 61 being coaxially and rotationally connected to the vertical section 12, the impeller 62 being coaxially and fixedly connected to the first rotating shaft 61 and located in the vertical section 12, and the end of the first rotating shaft 61 close to the slide cone 21 being fixed with the scraper 41;

[0054] In this way, the impeller 62 is driven to rotate by the dust removal air in the vertical section 12, and the impeller 62 drives the first rotating shaft 61 to rotate while driving the scraper 41 to rotate, and the impeller 62 changes the rotation rate according to the flow rate of the airflow in the vertical section 12, so as to change the rotation rate of the scraper 41.

[0055] Referring to 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 assembly 3 comprises a dust removal disc 31 horizontally installed on the inner wall of the separation tank 1, and the separation tank 1 is divided into upper and lower areas which are not communicated with each other, and a plurality of air inlet grooves 32 are formed on the side of the dust removal disc 31 facing the slide cone 21 in the vertical direction, and the plurality of air inlet grooves 32 are uniformly distributed along the circumferential direction of the dust removal disc 31, and a plurality of air outlet grooves 33 are formed on the side of the dust removal disc 31 away from the slide cone 21 in the vertical direction, one air outlet groove 33 is located between two air inlet grooves 32, and a plurality of filter holes 34 are formed on the side wall of the air inlet groove 32, which are communicated with the adjacent two air outlet grooves 33;

[0056] In this way, the gas sprayed from the vertical section 12 moves upward after colliding with the slide cone 21, enters the air inlet groove 32, and is filtered out from the air outlet groove 33 through the filter hole 34, so as to filter the suspended matter in the dust removal gas.

[0057] Referring to Figure 2 , Figure 4 , Figure 5 and Figure 6 , in order to clean the surface of the filter hole 34 in the air inlet groove 32, the second cleaning assembly 5 comprises a plurality of cleaning plates 51 and a plurality of connecting rods 52, one air inlet groove 32 is provided with one cleaning plate 51, the side wall of the cleaning plate 51 abuts with the side wall of the air inlet groove 32, one end of one connecting rod 52 is fixed with one cleaning plate 51, the other end extends through the dust removal disc 31 to above the dust removal disc 31, and the connecting rod 52 is elastically and slidably connected to the dust removal disc 31, and the cleaning plate 51 is attached to the top wall of the air inlet groove 32 in normal state;

[0058] The first rotating shaft 61 coaxially extends through the dust removal disc 31 to above the dust removal disc 31, and the first rotating shaft 61 is located on the side wall above the dust removal disc 31, and a first spiral groove 611 is formed along a spiral line with one turn, and the two ends of the first spiral groove 611 are communicated through a vertical first communication groove 612, so that the first spiral groove 611 and the first communication groove 612 form a space closed loop, and the end of the connecting rod 52 away from the cleaning plate 51 is provided with a first sliding block 521, and the first sliding block 521 can slide in the first spiral groove 611 and the first communication groove 612;

[0059] When the first rotating shaft 61 rotates, the first sliding block slides in the first spiral groove 611, and drives the connecting rod 52 to slide along the first spiral groove 611, and drives the cleaning plate 51 to slide downward to clean the filter holes 34 on the inner wall of the air inlet groove 32. When the first sliding block 521 slides to the first communication groove 612, the connecting rod 52 is elastically and slidably connected with the dust removal disc 31, at this time, the first sliding block 521 along the first communication groove 612 returns to the initial state, and the cleaning frequency of the cleaning plate 51 can also change with the flow rate of the gas entering the separation tank 1.

[0060] At the same time, by providing a plurality of air inlet grooves 32 and a plurality of cleaning plates 51, one cleaning plate 51 cleans one air inlet groove 32 to block part of the filter holes 34, while the cleaning plate 51 in another air inlet groove 32 returns to the initial state. Compared with a single air inlet groove 32, the number of filter holes 34 that can be used normally will not change greatly, and the air pressure in the separation tank 1 will not change greatly, which will not cause turbulence of the gas flow, forcibly push the impurities and particles at the filter holes 34 through the filter holes 34, and affect the filtering quality.

[0061] Referring to Figure 6 In order to further clean the filter holes 34, the second cleaning assembly 5 further comprises a vibrating plate 53 and an elastic member 54, and one vibrating plate 53 is arranged in each exhaust groove 33. The vibrating plate 53 is connected with the bottom wall of the exhaust groove 33 through the elastic member 54, and the elastic member 54 is a spring in the application. When the cleaning plate 51 cleans the air inlet groove 32, the air flow speed on both sides of the exhaust groove 33 changes, driving the vibrating plate 53 to swing, and the vibrating plate 53 cleans the filter holes 34 by hitting the exhaust groove 33 on both sides.

[0062] Referring to Figure 5 In order to reduce the particles scraped off from the side wall of the air inlet groove 32 by the cleaning plate 51 and re-entering the air inlet groove 32 along the air flow, the side wall of the air inlet groove 32, where the filter holes 34 are arranged, is provided with a flow guide groove 55, and the flow guide groove 55 gradually inclines downward toward the center of the dust removal disc 31 in a direction parallel to the diameter of the dust removal disc 31.

[0063] When the cleaning plate 51 scrapes the particles on the side wall of the air inlet groove 32 and drops them into the flow guide groove 55, the particles drop on the side close to the center of the dust removal disc 31 through the flow guide groove 55. Due to the conical shape of the sliding material 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 speed, which is more conducive to the particles falling in the flow guide groove 55.

[0064] Referring to Figure 2 , Figure 7 , Figure 8 and Figure 9In order to further remove the particles less than the filter hole 34 and dissolved in the liquid in the air, the gravity separator with the dust removal structure further comprises a third dust removal assembly 7, the third dust removal assembly 7 comprises a conical mounting disc 71, the mounting disc 71 is located above the dust removal disc 31, the conical head is upward, and the mounting disc 71 is coaxial with the first rotating shaft 61, the mounting disc 71 is fixed with the inner wall of the separation tank 1 through a mounting ring 72, and the mounting disc 71 and the mounting ring 72 divide the separation tank 1 into upper and lower areas which are not communicated with each other;

[0065] A plurality of first air inlet channels 73 are formed in the mounting disc 71 in a direction parallel to the generatrix of the mounting disc 71, the first air inlet channels 73 communicate the upper and lower areas of the mounting disc 71, and the plurality of first air inlet channels 73 are distributed in the circumferential direction of the mounting disc 71, a second rotating shaft 74 is coaxially arranged in the first air inlet channel 73, the second rotating shaft 74 is mounted on the mounting disc 71, and the second rotating shaft 74 is sequentially provided with an atomizing nozzle 75, a plurality of contact hairs 76 and a water absorption cylinder 77 sleeved on the second rotating shaft 74 from low to high, and the water absorption cylinder 77 is a sponge cylinder in the application;

[0066] A water storage tank 78 is fixed below the mounting disc 71, the water storage tank 78 is connected with each first air inlet channel 73 through a connecting pipe, and the connecting pipe is connected with the first air inlet channel 73 below the atomizing nozzle 75;

[0067] In this way, the gas discharged 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, the particles easily soluble in water are dissolved in the small water droplets in the airflow, then contact with the contact hairs 76, the contact hairs 76 block the small water droplets in the airflow on one hand, and block part of the particles in the airflow on the other hand, when the airflow passes through the water absorption cylinder 77, the water vapor in the airflow is absorbed by the water absorption cylinder 77, then the airflow is discharged from the first air inlet channel 73, and finally discharged from the gas outlet of the separation tank 1;

[0068] The water flow collected in the first air inlet channel 73 flows into the water storage tank 78 from the connecting pipe.

[0069] Referring to Figure 3 , Figure 8 and Figure 9 In order to increase the dust removal effect of the first dust removal assembly 2, a second water inlet channel 613 is formed in the first rotating shaft 61, and a water outlet is formed in the circumferential wall below the impeller 62 and communicated with the second water inlet channel;

[0070] The water storage tank 78 is communicated with the second water inlet channel 613, and a pressure control valve 614 is arranged at the communication position of 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 communicates the water storage tank 78 and the second water inlet channel 613;

[0071] 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 flows into the second water inlet channel 613, and the water flows out of the water outlet and flows onto the surface of the material sliding cone 21 or the artificial turf 22, enhancing the adsorption force on the particles;

[0072] At the same time, due to the presence of the pressure control valve 614, only when the water pressure plus the air pressure reaches a certain pressure, the pressure control valve 614 will start to work, thereby ensuring that the airflow will not flow back from the second water inlet channel 613 to the dust removal disc 31 below.

[0073] Referring to Figure 8 and Figure 9 , in order to shake off the adhering particles and water droplets on the contact whisk 76, and at the same time squeeze the water absorption cylinder 77 to squeeze out the water in it, the second shaft 74 is coaxially rotated on the mounting disc 71, and the second shaft 74 is located between the contact whisk 76 and the water absorption cylinder 77. The squeezing disc 79 is elastically slid along the axis of the second shaft 74 on the second shaft 74, and in normal state, the squeezing disc 79 has a tendency to move away from the water absorption cylinder 77;

[0074] A second spiral groove 731 is formed on the peripheral wall of the first air inlet channel 73 along a spiral line with one turn, and the two ends of the second spiral groove 731 are connected by a second communication groove 732 parallel to the axis of the second shaft 74, so that the second spiral groove 731 and the second communication groove 732 form a spatially closed loop. The second sliding block 791 is provided on the squeezing disc 79, and the second sliding block 791 can slide in the second spiral groove 731 and the second communication groove 732;

[0075] The second shaft 74 and the water pipe supplying water source for the atomizing nozzle 75 are connected through a rotating joint;

[0076] In this way, the second shaft 74 is rotated to drive the contact whisk 76 to rotate, and the adhering matter on the contact whisk 76 is shaken off by centrifugal force. At the same time, the second shaft 74 drives the squeezing disc 79 to rotate, and due to the presence of the second sliding block 791, the second spiral groove 731 and the second communication groove 732, the squeezing disc 79 reciprocates along the axis of the second shaft 74 during rotation of the second shaft 74, and the water in the water absorption cylinder 77 is squeezed out, ensuring that the water absorption performance of the water absorption cylinder 77 is always at a high level.

[0077] Referring to Figure 8 and Figure 9In order to control the rotating speed of the second rotating shaft 74 according to the flow rate of the airflow entering the separation tank 1, the gravity separator with the dust removal structure further comprises a second driving assembly 8 for driving the second rotating shaft 74 to rotate, the second driving assembly 8 comprising a first bevel gear 81 and a bevel gear plate 82, each second rotating shaft 74 extending below the mounting plate 71 and coaxially fixed with a first bevel gear 81, the bevel gear plate 82 being coaxially and rotatably connected to the separation tank 1 and coaxial with the first rotating shaft 61, the bevel gear plate 82 and the first rotating shaft 61 being connected to each other through a connecting rod;

[0078] The first rotating shaft 61 drives the bevel gear plate 82 to rotate, the bevel gear plate 82 drives the first bevel gear 81 to rotate, and then drives the second rotating shaft 74 to rotate.
