Description

Technical Field

[0001] The invention belongs to the technical field of industrial furnaces, in particular to a circulating smoke exhaust and dust removal device for industrial furnaces. Background Art

[0002] An industrial furnace is a thermal equipment that uses heat from fuel combustion or electrical energy conversion to heat materials or workpieces in industrial production. Broadly speaking, a boiler is also a type of industrial furnace, but people do not traditionally include it in the scope of industrial furnaces.

[0003] Due to incomplete combustion of coal, when the industrial furnace is working, the exhaust gas contains a large amount of smoke and dust, which needs to be simply filtered before it can be discharged. Since this part of the smoke contains a large amount of coal powder, it can be recycled and burned for the second time, so the corresponding dust removal equipment can recover the smoke. However, when the industrial furnace is continuously emitting, the general filtering and recovery equipment is difficult to work continuously for a long time due to excessive smoke accumulation, so it needs to be improved.

[0010] Furthermore, the upper and lower sides of the outer surface of the vacuum box are sleeved with wall-attached soft belts, the inner cavity of the wall-attached soft belt is filled with coolant, and horizontal through-tubes are symmetrically arranged on the left and right sides of the inner cavity of the wall-attached soft belt. The end of the horizontal through-tube away from the wall-attached soft belt is fixedly connected to the inner cavity of the drainage shell, and the interior of the drainage shell is also filled with coolant, which can be driven to circulate through the horizontal through-tube.

[0011] Furthermore, the lower surface of the torque motor is fixedly connected to the upper surface of the drainage shell, the top of the connecting plug plate is fixedly connected to the bottom of the inner cavity of the fixed disk shell through a through slot, and the end of the connecting pipe away from the vacuum box is fixedly connected to the bottom end of the transfer pipe.

[0013] Furthermore, the blocking inner plug includes a pressure-sensitive element, a conductive connecting rod is fixedly connected to the axis of the lower surface of the pressure-sensitive element, and a sealing sleeve is fixedly connected to the bottom end of the conductive connecting rod.

The inner cavity of the hollow top cover is fixedly connected to one side of the inner cavity of the fixed disk shell through a side air supply pipe. A specific partition for docking the filling plug tube is also provided on the inner wall of the air intake chimney, and the specific partition here has four evenly opened openings, which are respectively connected to the docking inner tubes in the initial state.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The device can process the exhaust gas discharged from the air intake chimney, and use the filter holes of the continuously rotating filter strips to perform cyclic filtration. Compared with fixed filter components, it can effectively increase the actual area of ​​the filtration equipment, thereby extending the filtration time of the device, and when the filter strips are rotating, the cleaning device located on the side of the fixed disk shell will suck out the smoke and dust inside the mesh of the filter strips to achieve a cleaning effect, so that the filter strips have a sustainable filtration function during the cyclic rotation process and have the ability to work continuously.

[0016] 2. When using a torsion device to control the rotation of the filter strip, in order to avoid slipping between the rotating chuck and the inner wall of the filter strip, the bidirectional thrust machine can pull the rotating chuck through the extension rods on the upper and lower sides to squeeze the inner wall of the filter strip, thereby increasing the friction between the filter strip and the rotating chuck and achieving a good torsion effect. When replacing the filter strip, the rotating chucks on both sides can be pulled apart to keep a certain gap between the rotating chuck and the filter strip, thereby making it easier to replace the old filter strip without having to consider connection issues such as fit tightness.

[0017] 3. When the cleaning equipment processes the filter strip, it will first open the opening blocked by the complementary slide plate, and then extract the smoke and dust in the mesh of the filter strip through the negative pressure inside the filling side shell. When the pressure inside the filling side shell is insufficient, the elastic force of the return spring will continue to push the complementary slide plate to seal the filling side shell, resulting in the filling side shell being unable to extract the mesh of the filter strip, thereby ensuring that the pressure of the filling side shell to extract the smoke and dust is large enough, with the pulling complementary slide plate as the basic line, to avoid the problem of insufficient adsorption capacity of the filling side shell, resulting in the inability to effectively clean the mesh of the filter strip.

[0018] 4. When the vacuum cleaner fails and needs maintenance, the built-in motor twists the filling plug 45° through the torque rod to separate the docking inner tube from the cover body. The opening of the cover body is aligned with the bottom end of the sealing sleeve. Then the air intake chimney cannot be exhausted, the gas is sealed inside, and no smoke enters the vacuum cleaner. Therefore, the vacuum cleaner can be maintained with confidence. As the sealing time increases, the air pressure in the air intake chimney will increase. At this time, the pressure on the pressure-sensitive element will also increase, thereby reminding the operator to release the pressure in time to avoid the problem of excessive pressure inside the air intake chimney and explosion.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0029] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a circulating smoke exhaust and dust removal device for an industrial furnace, comprising a dust collecting device 1, a drainage device 2 is symmetrically arranged on both sides of the dust collecting device 1, and an air intake chimney 3 is sleeved at the bottom of the drainage device 2;

[0030] The dust collecting device 1 comprises a fixed disk shell 11, a through slot 12 is provided at the bottom of the inner cavity of the fixed disk shell 11, a filter strip 13 is slidably connected to the inner wall of the fixed disk shell 11, the filter strip 13 is a whole annular strip connected end to end, and filter mesh holes are evenly provided, which can play a filtering role, a twisting device 4 is symmetrically arranged on the left and right sides of the inner wall of the filter strip 13, a cleaning device 5 is symmetrically arranged on the front and back sides of the inner wall of the fixed disk shell 11, and a dust collecting device 6 is arranged directly below the fixed disk shell 11;

[0031] The torsion device 4 includes a torque motor 41, the top end of the output shaft of the torque motor 41 is fixedly connected to an axial drum 42, vertical grooves are symmetrically provided on the front and rear sides of the inner cavity of the axial drum 42, and the inner cavity of the axial drum 42 is symmetrically provided with side sealing spring belts 44 through the vertical grooves, and rotating chucks 43 are symmetrically provided on the upper and lower sides of the inner cavity of the axial drum 42, and the rotating chucks 43 on the upper and lower sides can respectively squeeze the upper and lower sides of the inner wall of the filter strip 13, and then drive the filter strip 13 to rotate around the inner wall of the fixed disk shell 11 through friction under the torsion action of the torque motor 41, and a bidirectional thrust machine 45 is provided at the axis of the axial drum 42, and the upper and lower ends of the output shaft of the bidirectional thrust machine 45 are fixedly connected with extension pull rods 46.

[0032] The cleaning device 5 includes a filling side shell 51, and a complementary slide plate 52 is slidably connected to the side of the inner cavity of the filling side shell 51 close to the filter strip 13. Reset springs 53 are symmetrically arranged on both sides of the inner cavity of the complementary slide plate 52. A transfer tube 54 is fixedly connected to the axis of the inner cavity of the filling side shell 51 away from the complementary slide plate 52. The cleaning device 5 can perform reverse suction on the rotating filter strip 13, thereby sucking out the smoke and dust inside the filter port of the filter strip 13, thereby achieving a cleaning effect on the filter strip 13.

[0033] There are eight cleaning devices 5. One side of the outer surface of the filling side shell 51 is fixedly connected to the inner wall of the fixed disk shell 11, and the other side of the outer surface of the filling side shell 51 is slidably connected to the outer surface of the filter strip 13. The top of the transfer tube 54 is fixedly connected to one side of the inner cavity of the fixed disk shell 11 through the through hole. The upper and lower sides of the outer surface of the filter strip 13 are slidably connected to the inner wall of the fixed disk shell 11, the side of the rotating chuck 43 and one side of the inner wall of the filter strip 13 are mutually pressed, the upper and lower sides of the axial rotating drum 42 are rotatably connected to the inner wall of the fixed disk shell 11, and the upper surface of the torque motor 41 is fixedly connected to the lower surface of the fixed disk shell 11.

[0034] When the device is used, first insert the drainage devices 2 on both sides into the top of the air intake chimney 3, set up the dust collecting device 6 at the bottom, set a container for recovering soot at the bottom of the dust collecting device 6, and then discharge the industrial waste gas normally through the air intake chimney 3.

[0035] After the gas enters the side space of the fixed disk shell 11 through the drainage device 2, due to the obstruction of the filling side shell 51, the exhaust gas can only enter the middle part of the fixed disk shell 11 through the side of the filter strip 13. In this process, the filter strip 13 filters out the smoke in the smoke, so the smoke will be temporarily collected in the mesh of the filter strip 13.

[0036] When exhaust is discharged from the air intake chimney 3, the torque motor 41 slowly twists the axial drum 42. At this time, the axial drum 42 drives the upper and lower sides of the inner wall of the filter strip 13 to rotate through the rotating clamping plates 43 on the upper and lower sides. Therefore, the filter strip 13 continues to rotate inside the fixed disk shell 11, so the part where the filter strip 13 filters the exhaust gas is constantly changing, thereby avoiding the problem of continuous filtering work at a certain part of the filter strip 13 causing mesh blockage.

[0037] When the filter strip 13 rotates, the part used to filter the exhaust gas will pass through the cleaning devices 5 on both sides. At this time, the dust collecting device 6 below evacuates the interior of the filling side shell 51 through the switching tube 54, and then the complementary slide plate 52 slides to the side close to the switching tube 54 under the action of air pressure, thereby opening the opening of the filling side shell 51 on the side of the filter strip 13, so that the filling side shell 51 reversely absorbs the smoke and dust filtered out from the inside of the filter strip 13 through the opening, thereby achieving the effect of clearing the mesh of the filter strip 13.

[0038] After the portion of the filter strip 13 leaving the twisting device 4 is processed by the cleaning device 5, its mesh is unblocked, and after the next transfer work, it will return to the area where the twisting device 4 is located to perform the next gas filtering work, thereby achieving the effect of circulating filtration.

[0039] In order to ensure that the rotating chuck 43 can continuously twist the filter strip 13, during installation, the rotating chuck 43 will maintain a certain gap with the filter strip 13. After installation, the bidirectional thruster 45 controls the extension rods 46 at both ends, thereby pulling the rotating chucks 43 on the upper and lower sides to move in the direction of fitting the inner wall of the filter strip 13, so that the rotating chuck 43 and the inner wall of the filter strip 13 are squeezed against each other, ensuring that the friction between the rotating chuck 43 and the filter strip 13 is large enough. During the sliding process, the rotating chuck 43 will fill the gap between the axial drum 42 and the rotating clamp through the side sealing spring belt 44 to prevent smoke from entering the interior of the axial drum 42.

[0040] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of the first embodiment, the dust collecting device 6 includes a drainage outer shell 61, the inner wall of the drainage outer shell 61 is fixedly connected with a waterproof inner shell 62, the middle part of the inner wall of the waterproof inner shell 62 is fixedly connected with an exhaust box 63, the top of the inner cavity of the exhaust box 63 is fixedly connected with a connecting plug plate 64, the front and rear sides of the inner cavity of the exhaust box 63 are symmetrically provided with a pair of connecting pipes 65, the two sides of the bottom of the inner cavity of the exhaust box 63 are symmetrically provided with exhaust pipes 66, the exhaust box 63 performs exhaust work on the outside through the connecting pipes 65 and the connecting plug plate 64, and then exhausts air and dust through the exhaust pipe 66 at the bottom.

[0041] The upper and lower sides of the outer surface of the vacuum box 63 are sleeved with wall-attached soft belts 67, the inner cavity of the wall-attached soft belt 67 is filled with coolant, and horizontal through-tubes 68 are symmetrically arranged on the left and right sides of the inner cavity of the wall-attached soft belt 67. One end of the horizontal through-tube 68 away from the wall-attached soft belt 67 is fixedly connected to the inner cavity of the drainage shell 61, and the interior of the drainage shell 61 is also filled with coolant, which can be driven to circulate through the horizontal through-tube 68.

[0042] The lower surface of the torque motor 41 is fixedly connected to the upper surface of the drainage shell 61, the top of the connecting plug plate 64 is fixedly connected to the bottom of the inner cavity of the fixed disk shell 11 through the through slot 12, and the end of the connecting pipe 65 away from the vacuum box 63 is fixedly connected to the bottom end of the transfer connecting pipe 54.

[0043] The drainage device 2 includes a hollow top cover 21, a filling plug barrel 25 is rotatably connected to the axis of the lower surface of the hollow top cover 21, the inner cavity of the filling plug barrel 25 is evenly provided with docking inner tubes 26, the inner wall of the filling plug barrel 25 is evenly provided with blocking inner plugs 27, and a built-in motor 23 is fixedly connected to the axis of the inner wall of the hollow top cover 21, and the bottom end of the output shaft of the built-in motor 23 is fixedly connected to the axis of the bottom of the inner cavity of the filling plug barrel 25 through a torque rod 24.

[0044] The sealing inner plug 27 includes a pressure-sensitive element 271, a conductive connecting rod 272 is fixedly connected to the axis of the lower surface of the pressure-sensitive element 271, and a sealing sleeve 273 is fixedly connected to the bottom end of the conductive connecting rod 272. There are four sealing inner plugs 27 and four docking inner tubes 26. The upper surface of the pressure-sensitive element 271 is fixedly connected to the top of the inner wall of the filling plug tube 25, and the outer surface of the filling plug tube 25 is rotatably connected to the inner wall of the air intake chimney 3. The inner cavity of the hollow top cover 21 is fixedly connected to one side of the inner cavity of the fixed disk shell 11 through the side air supply pipe 22. A specific partition for docking the filling plug tube 25 is also provided on the inner wall of the air intake chimney 3, and the specific partition has four evenly opened openings, which are respectively connected to the docking inner tubes 26 in the initial state.

[0045] After the smoke passes through the filter strip 13, it is absorbed by the connecting plug plate 64 at the bottom of the fixed disk shell 11 and enters the interior of the exhaust box 63, and the exhaust box 63 also exhausts the dust collecting device 6 through the side connecting pipe 65, so the exhaust gas and smoke are absorbed into the areas on both sides of the exhaust box 63 through two different paths, and then the exhaust gas is discharged through the exhaust pipe 66 at the bottom to recover the usable smoke.

[0046] Since the exhaust gas directly discharged from the air intake chimney 3 contains relatively high thermal energy, the exhaust box 63 needs to be cooled by the wall-adhering soft belt 67 sleeved on the outer surface when continuously performing the vacuuming work. The coolant filled in the inner cavity of the wall-adhering soft belt 67 will circulate through the drainage shell 61 under the drainage action of the horizontal through pipe 68, thereby timely taking away the heat absorbed by the exhaust box 63 and achieving an effective cooling effect.

[0047] When the exhaust gas is discharged from the air intake chimney 3, it first passes through the cover body of its own inner wall, and then enters the interior of the hollow top cover 21 through the connected docking inner tube 26, and enters the interior of the fixed disk shell 11 through the drainage of the side air supply pipe 22. When the dust collection equipment 1 fails and needs maintenance, the built-in motor 23 twists the filling plug 25 by 45° through the torque rod 24, so that the docking inner tube 26 is separated from the cover body, and the opening of the cover body is aligned with the bottom end of the sealing sleeve 273. Then the air intake chimney 3 cannot be exhausted, the gas is blocked inside, and no smoke enters the dust collection equipment 1, so the dust collection equipment 1 can be maintained with confidence. As the blocking time increases, the air pressure in the air intake chimney 3 will increase. At this time, the pressure on the pressure-sensitive element 271 will also increase, thereby reminding the operator to release the pressure in time.

[0048] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
