Description

Technical Field

[0001] The present application relates to the technical field of air purification, and in particular to a waste gas purification device used in cement production. Background Art

[0002] The main process of cement production is to crush and grind the raw materials to make raw meal, then send the raw meal into a high-temperature kiln and calcine it with fuel to make clinker. Finally, the clinker is mixed with an appropriate amount of gypsum and ground into cement. The grinding operation of raw materials, coal powder and cement will generate a large amount of dust-containing exhaust gas, so exhaust gas purification equipment is needed to treat and purify it.

[0003] However, the existing dust recovery devices still have many shortcomings in practical applications, especially when dealing with the large amount of dust generated during the cement production process. First of all, the air intake design of most dust removal equipment is relatively concentrated or has a limited coverage range, which makes it difficult to effectively cover the entire long-line cement production line. As a result, in multiple dust-producing links such as transportation, crushing, calcination, cooling, and grinding, some areas cannot be fully included in the scope of the dust removal system. The existence of such dust removal blind spots causes these areas to continue to generate and spread dust during the production process, which not only affects the air quality in the workshop, but also increases the risk of pollution to the surrounding environment; in addition, existing dust collection devices often encounter the problem of dust adhering to the surface of the protective cover and then clogging the mesh of the protective cover, which not only affects the appearance of the equipment but also seriously hinders air circulation, reduces the dust collection efficiency, and greatly reduces the dust removal effect.

At this time, according to the Bernoulli effect, the gas flow rate close to the rotating inner and outer belts is greater than the air flow rate. Therefore, the inner and outer belts attract the air near them to approach them, and the dust in the air is adsorbed on the surface of the inner and outer belts. When the inner and outer belts drive the dust to move to the inner cavity of the installation shell, the second rotating shaft mechanism drives the dust collector through the transmission mechanism. The mechanism and the agitator rotate, and the first dust-removing cloth and the second dust-removing cloth hit the surface of the inner belt and the outer belt respectively, so that the dust on the surface of the inner belt and the outer belt falls off from their surfaces, and the agitator mixes the dust that falls into the inner cavity of the mounting shell with water, thereby realizing dust collection; in addition, since the inner belt and the outer belt are arranged directly above the production line, and the inner belt and the outer belt can cover the entire linear production line, the dust adsorption of the entire cement production line is realized, overcoming the problem that the existing dust recovery device has a small air intake coverage area and cannot meet the dust removal requirements of the long linear cement production line.

[0028] When the first elastic block is reset by the first sliding block and the first limiting sleeve, the friction block moves to one side and contacts the friction wheel again, and this is repeated, thereby realizing alternating rotation and vibration of the barrier rod, so that dust attached to the surface of the barrier rod falls off the surface of the barrier rod, overcoming the problem of existing dust suction devices in which dust adheres to the surface of the protective cover, blocks the mesh holes of the protective cover, causes air to not circulate, and reduces the dust suction efficiency of the device.

DETAILED DESCRIPTION

[0039] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0040] See also Figures 1 to 7 As shown, a waste gas purification device in cement production includes:

[0041] Two mounting shells 1 are symmetrically arranged on both sides, and the bottoms of the inner cavities of the two mounting shells 1 are filled with aqueous solution;

[0042] Two first rotating shaft mechanisms 2, the two first rotating shaft mechanisms 2 are respectively arranged at the upper parts of the inner cavities of the two mounting shells 1;

[0043] Two second rotating shaft mechanisms 3, the two second rotating shaft mechanisms 3 are respectively arranged at the bottom of the inner cavities of the two mounting shells 1;

[0044] Two third rotating shaft mechanisms 4, the two third rotating shaft mechanisms 4 are respectively arranged on one side of the upper part of the inner cavity of the two mounting shells 1;

[0045] The inner belt 5 is sleeved on the middle parts of the first rotating shaft mechanism 2, the second rotating shaft mechanism 3 and the third rotating shaft mechanism 4;

[0046] The outer belts 6 are sleeved on the front and rear sides of the first rotating shaft mechanism 2, the second rotating shaft mechanism 3 and the third rotating shaft mechanism 4. A plurality of friction blocks 601 are fixedly installed on the front side of the outer side of the front outer belt 6 at equal intervals, and a plurality of push blocks 602 are fixedly installed on the rear side of the outer side of the rear outer belt 6 at equal intervals.

[0047] The inner belt 5 and the outer belt 6 are arranged just above the production line. The lengths of the inner belt 5 and the outer belt 6 are set according to the length of the production line so that the inner belt 5 and the outer belt 6 can cover the entire production line.

[0048] The inner belt 5 and the outer belt 6 are both made of lightweight non-woven fabric, thereby reducing the load on the inner belt 5 and the outer belt 6 when the first rotating shaft mechanism 2, the second rotating shaft mechanism 3 and the third rotating shaft mechanism 4 drive the inner belt 5 and the outer belt 6 to rotate at high speed, reducing the power consumption during operation of the equipment, and at the same time increasing the friction resistance between the inner belt 5 and the outer belt 6 and the first rotating shaft mechanism 2, the second rotating shaft mechanism 3 and the third rotating shaft mechanism 4, thereby preventing relative sliding between the first rotating shaft mechanism 2, the second rotating shaft mechanism 3 and the third rotating shaft mechanism 4 and the inner belt 5 and the outer belt 6;

[0049] The protection mechanism 7 is arranged in the middle of the two mounting shells 1;

[0050] Multiple groups of dust collecting mechanisms 8 are symmetrically arranged on the left and right sides of the inner cavities of the two mounting shells 1;

[0051] Two agitators 9, the two agitators 9 are movably sleeved on the bottom of the inner cavity of the two mounting shells 1, and the front ends of the two agitators 9 are fixedly mounted with second passive wheels 901;

[0052] The two transmission mechanisms 10 are symmetrically arranged in front of the two mounting shells 1 .

[0053] See also Figures 1 to 3 As shown, the first rotating shaft mechanism 2 includes a first rotating shaft 201, which is fixedly sleeved on the upper part of the inner cavity of the mounting shell 1. A first inner wheel 202 is movably sleeved on the middle part of the first rotating shaft 201, and first outer wheels 203 are symmetrically sleeved on the front and rear sides of the first rotating shaft 201. The first inner wheel 202 and the first outer wheel 203 are in sliding contact.

[0054] Among them, the diameter of the first inner wheel 202 is smaller than the diameter of the first outer wheel 203, so that the inner belt 5 sleeved on the side of the first inner wheel 202 is located on the inner side of the outer belt 6 sleeved on the side of the first outer wheel 203, and a gap is generated between the inner side of the outer belt 6 and the outer side of the inner belt 5, thereby avoiding frictional contact between the inner belt 5 and the outer belt 6, causing wear of the inner belt 5 and the outer belt 6, and at the same time reducing the rotational load of the inner belt 5 and the outer belt 6. The contact surfaces of the first inner wheel 202, the first outer wheel 203 and the first rotating shaft 201 are smooth surfaces, thereby reducing the resistance when the inner belt 5 and the outer belt 6 pull the first inner wheel 202 and the first outer wheel 203 to rotate, thereby reducing the working load of the device.

[0055] See also Figures 1 to 4 As shown, the second rotating shaft mechanism 3 includes a second rotating shaft 301, which is fixedly sleeved on the bottom of the inner cavity of the mounting shell 1. A second inner wheel 302 is sleeved on the middle part of the second rotating shaft 301, and second outer wheels 303 are sleeved on the front and rear sides of the second rotating shaft 301. The second inner wheel 302 and the second outer wheel 303 are in sliding contact. A driving member 304 is fixedly installed on the rear side of the mounting shell 1. The output end of the driving member 304 is fixedly connected to the rear end of the second rotating shaft 301, and a driving wheel 305 is fixedly sleeved on the front side of the second rotating shaft 301.

[0056] The side surfaces of the second inner wheel 302 and the second outer wheel 303 are provided with a rubber coating, thereby increasing the frictional resistance between the second inner wheel 302 and the inner belt 5, and between the second outer wheel 303 and the outer belt 6, thereby preventing relative sliding between the second inner wheel 302 and the second rotating shaft mechanism 3, and between the second outer wheel 303 and the outer belt 6, which would reduce the rotation efficiency of the inner belt 5 and the outer belt 6.

[0057] The left second inner wheel 302 is fixedly connected to the left second rotating shaft 301, and the left second outer wheel 303 is movably connected to the left second rotating shaft 301, so that when the left driving member 304 drives the second rotating shaft 301 to rotate, the left second rotating shaft 301 drives the inner belt 5 to rotate through the second inner wheel 302;

[0058] The right second inner wheel 302 is movably connected to the right second rotating shaft 301, and the right second outer wheel 303 is fixedly connected to the right second rotating shaft 301, so that when the right driving member 304 drives the right second rotating shaft 301 to rotate, the right second rotating shaft 301 drives the outer belt 6 to rotate;

[0059] The rotation speed of the left driving member 304 is greater than that of the right driving member 304, so that the rotation speed of the inner belt 5 is greater than that of the right outer belt 6. As a result, when the inner belt 5 and the outer belt 6 rotate simultaneously, the suction force generated by the inner belt 5 is greater than the suction force generated by the outer belt 6, so that the dust adsorbed by the outer belt 6 is moved to the surface of the inner belt 5, thereby increasing the dust adsorption area by increasing the width of the outer belt 6, and improving the dust collection efficiency of the device by the high-speed rotation of the inner belt 5, thereby making the dust adsorption area, dust collection efficiency and power consumption of the device within the optimal range;

[0060] See also Figures 1 to 4 As shown, the third rotating shaft mechanism 4 includes a third rotating shaft 401, which is fixedly sleeved on the inner side of the upper part of the inner cavity of the mounting shell 1. A third inner wheel 402 is movably sleeved on the middle part of the third rotating shaft 401, and third outer wheels 403 are movably sleeved on the front and rear sides of the third rotating shaft 401. The third inner wheel 402 and the third outer wheel 403 are in sliding contact with each other.

[0061] Among them, the diameter of the third inner wheel 402 is larger than the diameter of the third outer wheel 403, so that the inner belt 5 is located on the inner side of the outer belt 6, avoiding direct contact between the inner belt 5 and the outer belt 6. The contact surface between the third inner wheel 402, the third outer wheel 403 and the third rotating shaft 401 is a smooth surface, thereby reducing the resistance when the inner belt 5 and the outer belt 6 pull the third inner wheel 402 and the third outer wheel 403 to rotate, thereby reducing the workload of the device.

[0062] See also Figure 1 、 Figure 2 、 Figure 5 and Figure 6As shown, the protective mechanism 7 includes two mounting plates 701, and the two mounting plates 701 are symmetrically fixedly sleeved on the front and rear sides of the adjacent surfaces of the two mounting shells 1. Multiple groups of mounting grooves 702 are equidistantly provided on the upper and lower sides of the adjacent surfaces of the two mounting plates 701. The middle parts of the multiple groups of mounting grooves 702 on the rear side are slidably sleeved with first sliding blocks 703. The adjacent sides of the upper and lower multiple groups of first sliding blocks 703 are fixedly installed with first elastic blocks 704. The first elastic blocks 704 are fixedly connected to the adjacent mounting grooves 702. The adjacent sides of the upper and lower first elastic blocks 704 are fixedly installed with cone blocks 70 5. The middle part of the first sliding block 703 is slidably connected to the first limiting sleeve 706. The middle parts of multiple groups of first sliding blocks 703 on the front side are slidably connected to the second sliding blocks 707. The adjacent sides of the upper and lower groups of second sliding blocks 707 are fixedly installed with second elastic blocks 708. The second elastic blocks 708 are fixedly connected to the adjacent mounting grooves 702. The middle parts of the multiple groups of second sliding blocks 707 are movably connected to the second limiting sleeves 709. The middle parts of the first limiting sleeves 706 and the second limiting sleeves 709 are fixedly connected to the blocking rod 710. The front side of the blocking rod 710 is fixedly connected to the friction wheel 711.

[0063] Among them, the first limiting sleeve 706 and the second limiting sleeve 709 are both made of rubber material, thereby increasing the friction resistance between the first limiting sleeve 706 and the first sliding block 703, and the second limiting sleeve 709 and the second sliding block 707, to avoid the blocking rod 710 from rotating when the device vibrates. The bottom surface of the cone block 705 is a smooth surface, thereby reducing the load when the push block 602 pushes the cone block 705 to move upward, reducing the resistance when the outer belt 6 drives the push block 602 to move, and thereby reducing the load on the device.

[0064] See also Figure 2 、 Figure 3 and Figure 7 As shown, the dust collecting mechanism 8 includes a mounting shaft 801, which is movably sleeved on one side of the inner cavity of the mounting shell 1, a first mounting sleeve 802 is fixedly sleeved on the middle part of the mounting shaft 801, and a plurality of groups of first dust-removing cloths 803 are equidistantly installed on the side circumference of the first mounting sleeve 802, a second mounting sleeve 804 is symmetrically fixedly sleeved on the front and rear sides of the mounting shaft 801, and a plurality of groups of second dust-removing cloths 805 are fixedly installed on the side circumference of the second mounting sleeve 804 at equal intervals, and a first passive wheel 806 is fixedly installed on the front end of the mounting shaft 801;

[0065] Among them, the first dust-removing cloth 803 and the second dust-removing cloth 805 are both made of non-woven fabrics, so that when the dust collecting mechanism 8 rotates, the first dust-removing cloth 803 and the second dust-removing cloth 805 collide with the sides of the inner belt 5 and the outer belt 6, so that the dust on the surface of the inner belt 5 and the outer belt 6 falls off from their surfaces. At the same time, the flexible first dust-removing cloth 803 and the second dust-removing cloth 805 can reduce the friction resistance between the first dust-removing cloth 803 and the inner belt 5, and the second dust-removing cloth 805 and the outer belt 6 at different rotation speeds, thereby reducing the load on the device.

[0066] See also Figures 1 to 4 As shown, the transmission mechanism 10 includes a first connecting wheel 1001, which is meshed with the second driven wheel 901 and the first connecting wheel 1001. A second connecting wheel 1002 is meshed between two adjacent first driven wheels 806. A third connecting wheel 1003 is meshed between the first driven wheel 806 and the driving wheel 305 on one side, and the driving wheel 305 on the other side is meshed with the first driven wheel 806. The first connecting wheel 1001, the second connecting wheel 1002 and the third connecting wheel 1003 are movably sleeved on the front of the mounting shell 1.

[0067] Among them, when the driving member 304 drives the active wheel 305 to rotate through the second rotating shaft 301, the active wheel 305 drives the second passive wheel 901 to rotate through the first connecting wheel 1001, and the second passive wheel 901 drives the agitator 9 to rotate. The agitator 9 stirs the water at the bottom of the inner cavity of the mounting shell 1, so that the dust falling off from the surface of the inner belt 5 and the outer belt 6 is mixed with the water. At the same time, the active wheel 305 drives multiple groups of first passive wheels 806 to rotate through multiple groups of second connecting wheels 1002 and the third connecting wheel 1003, and the first passive wheel 806 drives the mounting shaft 801 to rotate, and the mounting shaft 801 drives the first mounting sleeve 802 and the second mounting sleeve 804 to rotate. The first mounting sleeve 802 and the second mounting sleeve 804 respectively drive the first dust removing cloth 803 and the second dust removing cloth 805 to rotate, and the first dust removing cloth 803 and the second dust removing cloth 805 respectively hit the surface of the inner belt 5 and the outer belt 6, so that the dust on the surface of the inner belt 5 and the outer belt 6 falls off from their surfaces.

[0068] Working principle:

[0069] When the present invention is used, since the rotation speed of the left driving member 304 is greater than that of the right driving member 304, when the left and right driving members 304 are started, the left second rotating shaft mechanism 3 drives the inner belt 5 to rotate at a high speed, and the right second rotating shaft mechanism 3 drives the outer belt 6 to rotate at a low speed. At this time, according to the Bernoulli effect, the gas flow rate close to the rotating inner belt 5 and the outer belt 6 is greater than the air flow rate, so the inner belt 5 and the outer belt 6 attract the air near them to approach them, and the dust in the air is adsorbed on the surface of the inner belt 5 and the outer belt 6. When the inner belt 5 and the outer belt 6 drive the dust to move to the inner cavity of the mounting shell 1, at the same time, due to the second rotating shaft mechanism 3 passing through the transmission mechanism 1 0 drives the dust collecting mechanism 8 and the stirrer 9 to rotate, so that the first dust collecting cloth 803 and the second dust collecting cloth 805 hit the surface of the inner belt 5 and the outer belt 6 respectively, thereby causing the dust on the surface of the inner belt 5 and the outer belt 6 to fall off from their surfaces. The stirrer 9 mixes the dust that falls into the inner cavity of the mounting shell 1 with water, thereby collecting the dust. In addition, since the inner belt 5 and the outer belt 6 are arranged directly above the production line and can cover the entire production line, the dust of the entire cement production line can be adsorbed, thereby overcoming the problem that the existing dust recovery device has a small air intake coverage area and cannot meet the dust removal requirements of a long linear cement production line.

[0070] When the present invention is in use, when the front outer belt 6 drives the friction block 601 to move to one side and contact with the friction wheel 711, the friction block 601 drives the friction wheel 711 to rotate, and the friction wheel 711 drives the blocking rod 710 to rotate a certain angle. When the friction block 601 is separated from the friction wheel 711, the rear outer belt 6 drives the push block 602 to move to one side and contact with the cone block 705. The push block 602 pushes the cone block 705 to move away from the outer side of the outer belt 6. The cone block 705 pushes the first sliding block 703 to move away from the outer side of the outer belt 6. The first sliding block 703 pulls the first elastic block 704 to extend, and the first sliding block 703 passes through the first The limiting sleeve 706 drives the baffle rod 710 to move toward the outer side surface away from the outer belt 6 until the push block 602 is separated from the cone block 705. After the first elastic block 704 pulls the baffle rod 710 to reset through the first sliding block 703 and the first limiting sleeve 706, the friction block 601 moves to one side and contacts the friction wheel 711 again, and repeats this process, thereby realizing the alternating rotation and vibration of the baffle rod 710, so that the dust attached to the surface of the baffle rod 710 falls off from the surface of the baffle rod 710, overcoming the problem of the existing dust collection device, in which dust adheres to the surface of the protective cover, blocks the mesh of the protective cover, causes air to stagnate, and reduces the dust collection efficiency of the device.
