Description

Technical Field

[0001] The utility model relates to the technical field of industrial dust removal, in particular to an industrial dust removal device for preventing dust explosion. Background Art

[0002] Industrial vacuuming, also known as industrial dust removal, is the process of separating fine particles such as debris, smoke, or dust from the gas through dust removal equipment during industrial production processes such as polishing, cutting, grinding, crushing, incineration (combustion), etc.

[0003] In recent years, due to the rapid development of science and technology and the demand for industrialized production, the dust produced in the production and processing of many small and medium-sized enterprises is explosive. For example, flour, wood dust, metal alloy dust, resin dust, flax dust, etc. all have certain explosive characteristics. Especially in the production process of wood enterprises, wood powder has certain combustion and explosion risks. Most of the original wood enterprises use negative pressure dry bag dust collectors or small positive pressure dust collectors. During their production and processing, once iron nails are cut or in the sanding process, sparks are often generated. Sparks enter the dust collector along the air duct and reach certain conditions, which can lead to fire or explosion accidents. Utility Model Content

[0007] Furthermore, the interior of the circulation tank is filled with argon gas.

[0008] Furthermore, a partition is laterally fixedly connected inside the dust removal tank and between the inert gas pipe and the outlet pipe, a plurality of through holes are vertically penetrated through the upper surface of the partition, filter bags are detachably installed inside the plurality of through holes, a pulse device is fixedly connected to the upper surface of the partition, and a plurality of pulse heads of the pulse device extend to the interiors of the plurality of filter bags respectively.

[0009] Furthermore, a cover plate adapted to the top opening of the dust removal tank is detachably mounted on the top of the dust removal tank.

[0010] Furthermore, a first lap ring is fixedly connected to the outer surface of the cover plate, and a second lap ring matched with the first lap ring is fixedly connected to the open inner surface of the top of the dust removal tank.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, 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.

[0018] See also Figure 1-3 The utility model provides a technical solution: an industrial dust removal device for preventing dust explosion, comprising a base 1, a first support frame 2 is vertically fixedly connected to one side of the upper surface of the base 1, a dust removal tank 3 with open ends is fixedly connected to the top of the first support frame 2, an outer surface of the dust removal tank 3 is connected with an outlet pipe 8, an inert gas pipe 7 and a dust gas pipe 6 in sequence from top to bottom, a second support frame 10 is fixedly connected to the other side of the upper surface of the base 1, and a circulation tank 11 is fixedly connected to the top of the second support frame 11;

[0019] The outer surface of the circulation tank 11 is connected with the clean air exhaust pipe 14, the air inlet pipe 12 and the exhaust pipe 15 in sequence from top to bottom. The outer surface of the dust removal tank 3 is fixedly connected with the first air pump 9, the air inlet of the first air pump 9 is connected with the air outlet pipe 8, and the first connecting pipe 13 is connected between the air outlet of the first air pump 9 and the air inlet pipe 12. The outer surface of the circulation tank 11 is fixedly connected with the second air pump 16, the air inlet of the second air pump 16 is connected with the exhaust pipe 15, and the air outlet of the second air pump 16 is connected with the inert gas pipe 7 via a second connecting pipe 17.

[0020] The interior of the circulation tank 11 is filled with argon gas.

[0021] When the device is running, the argon gas in the circulation tank 11 will enter the interior of the dust removal tank 3 through the second air pump 16 and the second connecting pipe 17 through the inert gas pipe 7. The inert gas argon gas is used to prevent sparks from being generated in the dust removal tank 3, thereby avoiding dust explosions. After entering the dust removal tank 3, the argon gas will pass through the first air pump 9 and the first connecting pipe 13 together with the filtered exhaust gas and then return to the circulation tank 11 through the pipeline. Since the density of argon gas is greater than that of air, the argon gas will sink to the bottom of the circulation tank 11 and be drawn into the interior of the dust removal tank 3 again. The purified air will be discharged through the clean air exhaust pipe 14 at the top of the circulation tank 11, thereby ensuring the circulation effect of the argon gas.

[0022] A partition 4 is laterally fixedly connected inside the dust removal tank 3 and between the inert gas pipe 7 and the outlet pipe 8. A plurality of through holes are vertically penetrated through the upper surface of the partition 4. Filter bags 5 are detachably installed inside the plurality of through holes. A pulse device 18 is fixedly connected to the upper surface of the partition 4. A plurality of pulse heads of the pulse device 18 extend to the interior of a plurality of filter bags 5 respectively.

[0023] When the device is running, industrial waste will enter the dust removal tank 3 of the device through the dust pipe 6, and then move upward under the action of air pressure. In this process, the gas will pass through the filter bag 5 and enter the top of the partition of the dust removal tank 3 of the device and be discharged through the outlet pipe 8, while the dust impurities will be blocked by the filter bag 5. The pulse device 18 will be started intermittently to impact the dust impurities attached to the surface of the filter bag 5, so that they are detached from the filter bag 5, thereby ensuring the continuous operation capability of the device.

[0024] A cover plate 19 adapted to the top opening of the dust removal tank 3 is detachably mounted on the top of the dust removal tank 3 .

[0025] The cover plate 19 is used to close the opening at the top of the dust removal tank 3. When the filter bag 5 needs to be replaced, the cover plate can be removed for replacement.

[0026] A first lap ring 21 is fixedly connected to the outer surface of the cover plate 19 , and a second lap ring 22 matched with the first lap ring 21 is fixedly connected to the inner surface of the open top of the dust removal tank 3 .

[0027] The first lap ring 21 and the second lap ring 22 both play the role of strengthening the sealing effect.

[0028] The bottom end of the dust removal tank 3 contracts toward the central axis direction to form a funnel structure, and a closing piece 20 is detachably mounted on the bottom end of the dust removal tank 3 .

[0029] When it is necessary to discharge the dust, the closing piece 20 can be opened, and then the dust inside the device will be discharged from the inside of the dust removal tank 3 under the action of its own gravity.

[0030] When the device is running, the argon gas in the circulation tank 11 will enter the interior of the dust removal tank 3 through the second air pump 16 and the second connecting pipe 17 through the inert gas pipe 7. The inert gas argon gas is used to prevent sparks from being generated in the dust removal tank 3, thereby avoiding dust explosions. After entering the dust removal tank 3, the argon gas will pass through the first air pump 9 and the first connecting pipe 13 together with the filtered exhaust gas and then return to the circulation tank 11 through the pipeline. Since the density of argon gas is greater than that of air, the argon gas will sink to the bottom of the circulation tank 11 and be drawn into the interior of the dust removal tank 3 again. The purified air will be discharged through the clean air exhaust pipe 14 at the top of the circulation tank 11, thereby ensuring the circulation effect of the argon gas.
