Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a movable wet dust collector for diversion tunnel excavation. Background Art

[0002] A dust collector is a device that separates dust from flue gas. Construction operations inside the diversion tunnel will cause various types of dust. When using ventilation to discharge dust inside the diversion tunnel, it is easy for the dust to flow inside the diversion tunnel, and on-site operators are easily affected and harmed by the dust. Using a traditional filter screen type filter is very likely to cause the filter screen to become blocked. If the filter screen is not replaced in time after being blocked, the filtering effect will be reduced. When using a wet dust collector, the water rotates with the motor, which will increase energy consumption and filtration costs.

[0003] A slag scraping machine towed tunnel wet dust removal device with the publication number of CN221373645U mainly includes a dust removal box, a ventilation device, a moving device, and an electric control box. The slag scraping machine towed tunnel wet dust collector is installed between the slag scraping machine slag transport vehicle and the support, and can enter the blasting construction area together with the slag scraping machine. The moving device connects the wet dust collector and the slag scraping machine through a coupler, which is convenient for installation and disassembly. The device moves relying on the wheels installed at its bottom, and the stability of the device is ensured. The dust removal box mainly includes a mixed air box, nozzles, and a wet string grid plate. After the high-temperature dirty air is sucked into the dust removal box, it undergoes spray dust removal and wet string grid plate dust removal to achieve secondary dust removal and temperature reduction. At the same time, the wet string grid plate is set at a certain inclination angle, and the filtered sewage can be converged to the sewage outlet and discharged from the device. The purified air flow is discharged into the tunnel to realize the air flow circulation inside the tunnel.

[0004] Deficiencies in the prior art: The existing wet dust collector needs to use nozzles to atomize and spray water, and then uses a wet string grid plate similar to a filter screen to filter dust. Although it has a vibration effect, the large-volume dust particles formed are still likely to block the wet string grid plate, which will affect its dust removal effect and further affect the dust removal efficiency of the tunnel. Summary of the Utility Model

[0005] Therefore, the embodiment of the utility model provides a movable wet dust collector for diversion tunnel excavation to solve the problem that in the prior art, due to the easy blockage of the filtering structure inside the dust collector, the air cannot be filtered continuously and stably, which will affect the dust removal efficiency of the tunnel.

[0027] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to the attached drawings of the specification Figure 1 , a mobile wet dust collector for diversion tunnel excavation in this embodiment includes a dust collector main body 2, and further includes:

[0029] A fixing mechanism 1, which is arranged at the bottom of the dust collector main body 2 and is used for installing and moving the dust collector main body 2;

[0030] An air inlet mechanism 3, which is arranged on the outer wall of the dust collector main body 2 and is communicated with the inside of the dust collector main body 2, and is used for conveying dust into the dust collector main body 2. Through the air inlet mechanism 3, the air with dust in the tunnel can be conveniently conveyed into the dust collector main body 2. The air in the tunnel can be filtered by the clean water inside the dust collector main body 2, and thus the air in the tunnel can be conveniently filtered, and the dust removal efficiency in the tunnel can be improved.

[0031] In order to conveniently convey the dust in the tunnel into the dust collector main body 2, as Figures 1-3 shown, the air inlet mechanism 3 includes two collecting pipes 301. The two collecting pipes 301 are arranged on the outer side of the dust collector main body 2. A plurality of exhaust pipes 302 inserted into the inside of the dust collector main body 2 are fixedly installed on the inner sides of the two collecting pipes 301. One ends of the two collecting pipes 301 are fixedly installed with shunt pipes 303. One ends of the two shunt pipes 303 away from the collecting pipes 301 are fixedly installed with a diversion pipe 304. A fan 305 is fixedly installed on the top of the diversion pipe 304. When the fan 305 works, the dust is conveyed into the two collecting pipes 301 through the diversion pipe 304 and the two shunt pipes 303. Through the exhaust pipes 302, the air with dust can push the water flow in the water storage tank 201 to move, so that the water flow can conveniently adsorb the dust.

[0032] In order to conveniently move the device and discharge the sewage dissolved with dust, as Figures 1-3As shown in the figure, the fixing mechanism 1 includes a fixing base 101. Support wheels 102 are rotatably installed on both sides at both ends of the inner wall of the fixing base 101. A support frame 103 is fixedly installed on the top of the fixing base 101. The dust collector main body 2 includes a water storage tank 201. The outer wall of the bottom of the water storage tank 201 is fixedly connected to the top of the support frame 103. A butterfly valve 202 for sewage discharge is fixedly installed at the lower end of the water storage tank 201. A sewage discharge pipe 203 is fixedly installed at the bottom of the butterfly valve 202. The setting of the support wheels 102 enables the device to be moved conveniently. The setting of the butterfly valve 202 and the sewage discharge pipe 203 enables the sewage dissolved with dust and the dust deposited at the bottom of the water storage tank 201 to be discharged from the inside of the water storage tank 201 conveniently, so that the device can filter the air in the tunnel continuously and stably.

[0033] In order to stably transport the dust into the water storage tank 201, as Figures 2-3 shown, two gas collecting pipes 301 are movably sleeved outside the water storage tank 201. The inner diameter dimension of the gas collecting pipe 301 is the same as the outer diameter dimension of the water storage tank 201. The diameter dimension of the diversion pipe 304 is larger than the diameter dimension of the shunt pipe 303. The diameter dimension of the shunt pipe 303 is the same as the diameter dimension of the gas collecting pipe 301. The diameter dimension of the gas collecting pipe 301 is the same as the diameter dimension of the exhaust pipe 302. The water storage tank 201 can install and fix the gas collecting pipe 301 and the exhaust pipe 302. The diversion pipe 304 can stably transport the air with dust into the two gas collecting pipes 301 through the shunt pipe 303.

[0034] In order to quickly transport the dust into the clear water inside the water storage tank 201, as Figures 2-3 shown, the outer wall of the exhaust pipe 302 is movably connected to the hole opened on the inner wall of the water storage tank 201. The included angle between the exhaust pipe 302 and the tangential direction of the water storage tank 201 is 30°. There are twenty-four exhaust pipes 302 at the same height, and the twenty-four exhaust pipes 302 are arranged in an equally spaced circular arrangement. The angle between the exhaust pipe 302 and the tangential direction of the water storage tank 201 is 30°, so that the air can push the clear water inside the water storage tank 201 to rotate, and then the dust in the air can be quickly dissolved in the clear water inside the water storage tank 201.

[0035] The specific implementation scenario is as follows: When cleaning the dust in the diversion tunnel, the device moves on the ground through the support wheels 102, and can conveniently move the device to the required position. Then, through the operation of the fan 305, the air carrying dust in the tunnel can enter the diversion pipe 304. After being transported by the two shunt pipes 303, the air enters the two gas collecting pipes 301. Then, along with the transportation of the air, the air carrying dust can enter the inside of the water storage tank 201 through the twenty-four exhaust pipes 302 at the same height, and then can push the water flow inside the water storage tank 201 to rotate, so that the dust in the air can quickly dissolve in water or precipitate to the inner bottom of the water storage tank 201, and then the air can be quickly filtered. Then, by opening the butterfly valve 202, the dust and sewage precipitated at the inner bottom of the water storage tank 201 can be discharged through the sewage pipe 203. The settings of the fan 305 and the exhaust pipes 302 enable the air carrying dust to push the water flow inside the water storage tank 201 to rotate, so that the water flow can quickly adsorb and precipitate the dust in the air, and the dust removal efficiency in the tunnel can be improved. This implementation mode specifically solves the problem that in the prior art, the dust filter by the filter screen of the dust collector is prone to blockage, which will affect the dust removal efficiency of the tunnel.

[0036] Although the present invention has been described in detail above with general descriptions and specific embodiments, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
