Description

Technical Field

[0001] The utility model belongs to the technical field of sludge treatment, and in particular relates to a tower wall cleaning device for an acid mist purification tower. Background Art

[0002] Acid mist purification tower, also known as acid gas purification tower, acid mist purification tower, acid mist absorption tower, waste gas purification tower and fiberglass acid mist purification tower, plays the role of removing harmful gases in exhaust gas. It has the characteristics of wide application range, high purification efficiency, low equipment resistance and small footprint. During the operation of the acid mist purification tower, the tower wall needs to be cleaned and maintained regularly to avoid corrosion of the tower body.

[0003] In the prior art, a spray device is provided inside the acid mist purification tower. During the neutralization reaction between the acid gas in the exhaust gas and the alkaline solution, the tower wall is also cleaned. However, during the rising process of the gas, when the gas hits the tower wall, the residue inside the gas will adhere to the inside of the water retained on the tower wall. Although the spray device will continue to spray the tower wall, some residues will still adhere to the surface of the tower wall, and after the device stops working, water droplets and residues will remain on the tower wall, making it impossible to thoroughly clean the tower wall.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a tower wall cleaning device for an acid mist purification tower to overcome the above technical problems existing in the existing related technology.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model is a tower wall cleaning device for an acid mist purification tower, comprising a first shell, a second shell is slidably connected to the surface of the first shell, a plurality of teeth distributed at equal intervals are fixedly connected to the inner wall of the first shell, a motor is fixedly connected to the inner wall of the second shell away from one end of the first shell, a gear is fixedly connected to the output end of the motor, the gear is meshed with the teeth, a first electric telescopic rod is fixedly connected to the surface of the first shell, and a descaling mechanism is fixedly connected to the telescopic end of the first electric telescopic rod;

[0008] The descaling mechanism includes a fixed block, which is fixedly installed on the telescopic end of the first electric telescopic rod, and the fixed block is rotatably connected to two evenly arranged connecting blocks inside, and a connecting rod is fixedly connected to the surface of the fixed block, and springs are fixedly connected to the opposite surfaces between the two connecting blocks, and the other ends of the two springs are fixedly connected to the connecting rod, a brush wheel is rotatably connected to the connecting block, and a fixed plate is fixedly connected to one end of the connecting rod away from the fixed block, and a plurality of scraping rods arranged at equal distances are fixedly connected to one side of the fixed plate.

[0009] Furthermore, one end of the first shell is fixedly connected to a water tank, the interior of the water tank is fixedly connected to a water pump, the water outlet of the water pump is fixedly connected to a first water pipe, the other end of the first water pipe is fixedly connected to two second water pipes, and the second water pipes are fixedly connected to a nozzle.

[0010] Furthermore, the first water pipe runs through the water tank.

[0011] Furthermore, the two second water pipes are distributed in a circle at one end of the first water pipe.

[0012] Furthermore, a plurality of second electric telescopic rods distributed at equal intervals are fixedly connected to the surface of the second shell.

[0013] Furthermore, the telescopic end of the second electric telescopic rod is used to install a crawler walking mechanism.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model uses the brush wheel arranged on the descaling mechanism. First, the brush wheel pair facing the rotation direction of the device inside the descaling mechanism rubs for the first time, so that a part of the residue on the tower wall of the device falls off. Then, as the device rotates, the scraper rod will not only scratch the tower wall part at the current position to make the residue fall from the tower wall, but also scratch the tower wall again when it rotates to the tower wall rubbed by the brush wheel, and the residue will fall off the tower wall, so as to supplement the tower wall part just rubbed by the brush wheel, and further clean the tower wall. Then, another brush wheel will also rub the tower wall to clean the tower wall again, and this brush wheel will drive the currently connected connecting block to rotate slightly in the opposite direction of the device inside the fixed block, and pull the currently fixed spring to stretch, and then the spring will elastically deform to pull the connecting block to reset, and then rub the just rubbed part again to avoid the situation of unclean cleaning, thereby avoiding the situation that the device does not clean the tower wall.

[0016] 2. When the output end of the motor rotates, the control gear drives the first shell to rotate through the meshing teeth. When the motor is working, the second shell remains stationary, thereby avoiding the descaling mechanism from affecting the movement trajectory of the device during the cleaning process. At the same time, the rotation of the first shell can further expand the contact area of ​​the several descaling mechanisms arranged on the surface with the tower wall, so that the descaling mechanism can clean the tower wall more fully.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0028] See also Figure 1-Figure 5 As shown, the utility model is a tower wall cleaning device for an acid mist purification tower, comprising a first shell 1, a second shell 2 is slidably connected to the surface of the first shell 1, a plurality of equally spaced teeth 101 are fixedly connected to the inner wall of the first shell 1, a motor 7 is fixedly connected to the inner wall of the second shell 2 away from one end of the first shell 1, a gear 701 is fixedly connected to the output end of the motor 7, the gear 701 is meshed with the teeth 101, a plurality of equally spaced first electric telescopic rods 3 are fixedly connected to the surface of the first shell 1, and a descaling mechanism 5 is fixedly connected to the telescopic end of the first electric telescopic rod 3;

[0029] The descaling mechanism 5 includes a fixed block 501, which is fixedly installed on the telescopic end of the first electric telescopic rod 3, and the fixed block 501 is internally rotatably connected with two evenly arranged connecting blocks 504, and the surface of the fixed block 501 is fixedly connected with a connecting rod 502, and the opposite surfaces between the two connecting blocks 504 are fixedly connected with springs 503, and the other ends of the two springs 503 are fixedly connected to the connecting rod 502, and the connecting block 504 is internally rotatably connected with a brush wheel 505, and the end of the connecting rod 502 away from the fixed block 501 is fixedly connected with a fixed plate 506, and one side of the fixed plate 506 is fixedly connected with a plurality of equidistantly arranged scraping rods 507.

[0030] When the device is inside the tower, and when the scraper 507 and the two brush wheels 505 are in contact with the tower wall, the motor 7 is turned on, and at the same time, the output end of the motor 7 starts to rotate, and then the gear 701 starts to rotate following the output end of the motor 7, and through the meshing of the gear 701 and the teeth 101, the first shell 1 starts to rotate, and then the first electric telescopic rods 3 fixed on the surface start to rotate, and at the same time, the brush wheel 505 that turns toward the device follows the rotation of the device and rubs the tower wall for the first time, so that a small part of the residue on the surface of the tower wall falls off, and at the same time, this brush wheel 505 drives the connecting block 504 to rotate a part of the direction opposite to the device, and the spring 503 on this connecting block 504 absorbs the friction from The energy of the current connecting block 504 is contracted, and then several scrapers 507 located in the middle part will scratch the residue on the tower wall currently in contact, and the residue will continue to fall after being scratched. Finally, another brush wheel 505 will rub the remaining residue to cause the residue to fall. At the same time, this brush wheel 505 also drives the connecting block 504 to rotate a small part in the opposite direction of the device, and the current connecting block 504 will pull the spring 503, prompting the currently fixed spring 503 to stretch, and then the spring 503 will pull the currently fixed connecting block 504 to reset, and at the same time, the brush wheel 505 will rub the residue again during the reset process to cause the residue to fall.

[0031] Through the controllable extension and retraction of the first electric telescopic rod 3, it is convenient to better control the descaling mechanism 5 to fit the tower wall, and at the same time, the overall diameter of the device can be changed, so that the device can be adapted to more acid mist purification towers with different diameters;

[0032] When the output end of the motor 7 rotates, the control gear 701 drives the first shell 1 to rotate through the meshing teeth 101, and then the second shell 2 remains stationary during the operation of the motor 7, thereby avoiding the descaling mechanism 5 from affecting the movement trajectory of the device during the cleaning process. At the same time, the rotation of the first shell 1 can further expand the contact area of ​​the several descaling mechanisms 5 arranged on the surface with the tower wall, so that the descaling mechanism 5 can clean the tower wall more fully.

[0033] Through the brush wheel 505 arranged on the descaling mechanism 5, the brush wheel 505 in the descaling mechanism 5 facing the rotation direction of the device first rubs against the descaling mechanism 5, so that part of the residue on the tower wall of the device falls off. Then, as the device rotates, the scraper rod 507 not only scrapes the tower wall part at the current position to make the residue fall from the tower wall, but also scratches the tower wall rubbed by the brush wheel 505 again when it rotates to make the residue fall from the tower wall, and the tower wall part just rubbed by the brush wheel 505 is supplemented, so as to clean the tower wall. For further cleaning, another brush wheel 505 will also rub against the tower wall to clean the tower wall again, and this brush wheel 505 will drive the currently connected connecting block 504 to rotate slightly inside the fixed block 501 in the opposite direction of the device, and pull the currently fixed spring 503 to stretch, and then the spring 503 will elastically deform and pull the connecting block 504 to return to its original position, and then rub the just rubbed part again to avoid the situation of unclean cleaning, thereby avoiding the situation that the device does not clean the tower wall thoroughly.

[0034] In addition, in specific applications, the first electric telescopic rod 3 is an existing mechanical structure, including an inner rod, an outer rod, and a motor. The motor can drive the inner rod to slide freely inside the outer rod, thereby allowing the first electric telescopic rod 3 to be freely extended and retracted.

[0035] In one embodiment, for the above-mentioned first shell 1, one end of the first shell 1 is fixedly connected to a water tank 4, the interior of the water tank 4 is fixedly connected to a water pump 401, the water outlet end of the water pump 401 is fixedly connected to a first water pipe 402, the other end of the first water pipe 402 is fixedly connected to two second water pipes 403, and the second water pipes 403 are fixedly connected to a nozzle 404.

[0036] During the operation of the device, the water pump 401 is turned on, the water inside the water tank 4 is absorbed and pressurized by the water pump 401, and is transported to the inside of the first water pipe 402 through the water outlet, and is transported to the inside of the two second water pipes 403, and is finally sprayed onto the tower wall through the nozzle 404.

[0037] Through the rotation of the first shell 1, the water tank 4 is fixed to the first shell 1, and thus the water tank 4 will also rotate, and then the second water pipe 403 will also rotate, so that the range of the nozzle 404 spraying to the tower wall is more comprehensive, and at the same time, the water sprayed on the tower wall will moisten the tower wall, and the tower wall will also be moistened to avoid drying of the tower wall, thereby causing some residues to dry on the tower wall and not easily detach from the tower wall.

[0038] In addition, in specific applications, the water pump 401 is an existing mechanical structure, and the water pump 401 will pressurize the water inside the water tank 4, so that the water inside the nozzle 404 sprays onto the tower wall with a greater impact, and the residue will also fall off the tower wall during the impact.

[0039] In one embodiment, for the first water pipe 402 , the first water pipe 402 runs through the water tank 4 .

[0040] In one embodiment, for the second water pipe 403 , two second water pipes 403 are distributed in a circle at one end of the first water pipe 402 .

[0041] In one embodiment, for the second housing 2 , a plurality of second electric telescopic rods 6 are fixedly connected to the surface of the second housing 2 and are evenly distributed.

[0042] In addition, in specific applications, the second electric telescopic rod 6 and the first electric telescopic rod 3 have the same mechanical structure and the same working principle.

[0043] In one embodiment, for the second electric telescopic rod 6, the telescopic end of the second electric telescopic rod 6 is used to install a crawler walking mechanism.

[0044] By installing the crawler walking mechanism, the device can be lifted and lowered linearly on the tower wall, making it easier to clean the tower wall.

[0045] Through the controllable extension and retraction of the second electric telescopic rod 6, the crawler walking mechanism can fit more fully with the tower wall, thereby increasing the friction between the crawler walking mechanism and the tower wall, so that the crawler walking mechanism moves as a whole through the friction limiting device with the tower wall, and then the device can be driven to move and lift only when the crawler walking mechanism is turned on.

[0046] In addition, in specific applications, the crawler is an existing mechanical structure with a built-in motor, and is composed of a driving wheel, a supporting wheel, a guide wheel, a towing wheel, a crawler, a tensioning device and a buffer spring. The crawler is made of rubber. The crawler is driven by a driving wheel and is a flexible chain ring around the driving wheel, the road wheel, the inducer wheel and the support wheel. The crawler consists of a track plate and a track pin, and the track pin connects the track plates to form a track chain. There are holes at both ends of the track plate, which mesh with the driving wheel, and there are induction teeth in the middle to regulate the track.

[0047] In summary, with the aid of the above technical solution of the utility model, when the device is located inside the mist acid purification tower and is ready to clean the tower wall, the first electric telescopic rod 3 is first driven to control the descaling mechanism 5 to move, until the brush wheel 505 and the scraper rod 507 are in contact with the tower wall, the electric telescopic rod is closed, and then the second electric telescopic rod 6 is turned on to drive the crawler walking mechanism to move. When the crawler walking mechanism is in contact with the tower wall, the second electric telescopic rod 6 is also closed, and the motor 7 is turned on at the same time. The output end of the motor 7 controls the gear 701 to start rotating, and then the gear 701 gradually drives the first shell 1 to rotate through the meshing with the teeth 101, and the water pump 401 is turned on at the same time. The water pump 401 absorbs the water inside the water tank 4 and transmits it to the inside of the first water pipe 402 at a higher pressure, and finally sprays it out through the nozzle 404 and impacts the tower wall to moisten the tower wall. After a part of the residue on the tower wall is impacted, a part of it falls off from the tower wall;

[0048] At the same time, the first electric telescopic rod 3 rotates accordingly, and then the descaling mechanism 5 rotates accordingly, and then the brush wheel 505 that turns toward the device follows the rotation of the device to perform initial friction on the tower wall, causing a small part of the residue on the tower wall surface to fall off, and at the same time, this brush wheel 505 drives the connecting block 504 to rotate a part in the opposite direction of the device, and the spring 503 on this connecting block 504 absorbs the energy from the current connecting block 504 and shrinks, and then the scrapers 507 located in the middle part will scrape the residue on the tower wall currently in contact with. The residue will continue to fall after being scratched, and finally another brush wheel 505 will rub the remaining residue to make it fall. At the same time, this brush wheel 505 also drives the connecting block 504 to rotate a small part in the opposite direction of the device, and the current connecting block 504 will pull the spring 503, prompting the currently fixed spring 503 to stretch, and then the spring 503 will pull the currently fixed connecting block 504 to reset, and at the same time, the brush wheel 505 will rub the residue again during the reset process to make the residue fall.

[0049] Through the above technical scheme, 1. through the brush wheel 505 arranged on the descaling mechanism 5, first, the brush wheel 505 in the descaling mechanism 5 facing the rotation direction of the device is rubbed for the first time, so that part of the residue on the tower wall of the device falls off, and then as the device rotates, the scraper rod 507 will not only scratch the tower wall part at the current position during the following rotation process to make the residue fall from the tower wall, but also when the tower wall rubbed by the brush wheel 505 is scratched again, the residue falls off the tower wall, and the tower wall part just rubbed by the brush wheel 505 is supplemented to further clean the tower wall, and then another brush wheel 505 will also rub the tower wall to clean the tower wall again, and this brush wheel 505 will drive the currently connected connecting block 504 to move toward the device inside the fixed block 501 The opposite direction rotates slightly and pulls the currently fixed spring 503 to stretch, and then the spring 503 undergoes elastic deformation to pull the connecting block 504 to reset, and then the rubbed part is rubbed again to avoid unclean cleaning, thereby preventing the device from cleaning the tower wall uncleanly; 2. When the output end of the motor 7 rotates, the control gear 701 drives the first shell 1 to rotate through the meshing teeth 101, and then the second shell 2 remains stationary during the operation of the motor 7, thereby preventing the descaling mechanism 5 from affecting the movement trajectory of the device during the cleaning process. At the same time, the rotation of the first shell 1 can further expand the contact area of ​​the several descaling mechanisms 5 arranged on the surface with the tower wall, so that the descaling mechanisms 5 can clean the tower wall more fully.
