Description

Technical Field

[0001] The utility model relates to the technical field of air flow mill equipment, in particular to an air flow mill ultrafine powder cleaning, oxygen exhaust and dust removal system. Background Art

[0002] The air flow mill is a process where compressed air is accelerated into supersonic airflow through a Laval nozzle and then injected into the crushing zone to fluidize the material (the airflow expands into a fluidized bed, suspends and boils, and collides with each other), so each particle has the same motion state. In the crushing zone, the accelerated particles collide with each other at the intersection of each nozzle and are crushed. The crushed material is transported to the classification zone by the rising airflow, and the horizontally arranged classification wheel screens out the fine powder that meets the particle size requirements, and the coarse powder that does not meet the particle size requirements returns to the crushing zone for further crushing. The fine powder screened by the classification wheel also contains some ultrafine powder. When the fine powder passes through the cyclone separator, the ultrafine powder in the fine powder is separated and stored in the powder storage container of the filter system. This part of the ultrafine powder needs to be cleaned regularly.

[0003] In the prior art, during the cleaning process of ultrafine powder in the air flow mill, the gas containing ultrafine powder is easily dispersed into the external space, thereby causing environmental pollution in the workshop and causing harm to the health of employees. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model proposes an air flow mill ultrafine powder cleaning, oxygen exhaust and dust removal system.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A system for cleaning and exhausting oxygen and dust removing of ultrafine powder of an air flow mill comprises a powder storage barrel connected to an air flow mill device, the powder storage barrel is connected to a dust removal structure, the dust removal structure comprises a water flow portion for absorbing dust, a collecting portion for collecting dust, and a connecting channel for connecting the water flow portion and the collecting portion, and a powder suction component for introducing fine dust in the water flow portion into the collecting portion is arranged in the connecting channel.

[0007] Preferably, the water passing part includes a water storage bucket, one end cover of the connecting channel is arranged on the water storage bucket so that the water storage bucket is isolated from the external space, and an exhaust pipe is arranged on the powder storage bucket, and the exhaust pipe is connected to the water storage bucket. Through the above improvements, the ultrafine powder discharged from the powder storage bucket with the airflow will first enter the water storage bucket, wherein the relatively larger dust particles in the ultrafine powder will be adsorbed by water when passing through the water storage bucket and remain in the water, and in addition, the remaining ultrafine powder with a smaller size will float out of the water surface with the airflow and continue to be collected by the collection part, thereby realizing the recovery of the ultrafine powder.

[0008] Preferably, the collecting part includes a dust collecting bucket and a dust collecting bag arranged in the dust collecting bucket, and the dust collecting bag is connected to the connecting channel. Through the above improvements, the remaining ultrafine powder with a smaller size will enter the dust collecting bag under the action of the powder suction component, thereby realizing the collection of the ultrafine powder.

[0009] Preferably, the powder suction assembly includes a powder suction blade rotated in the connecting channel, and a driving unit for driving the powder suction blade to rotate. Through the above improvements, when the driving unit drives the powder suction blade to rotate, the powder suction blade will move the ultrafine powder of smaller size toward the collecting part, so that the remaining ultrafine powder is collected in the collecting part, thereby greatly improving the dust removal effect.

[0010] Preferably, the water flow part is detachably connected to the connecting channel, and a first connecting protrusion is formed on the connecting channel, and a second connecting protrusion connected to the first connecting protrusion is formed on the water flow part. Through the above improvement, the first connecting protrusion and the second connecting protrusion cooperate to make it easier to disassemble the water flow part, so as to replace the water in the water flow part and clean the water flow part, and to make it easier for the operator to perform subsequent maintenance.

[0011] Preferably, the powder suction blades are horizontally arranged in the connecting channel, and the driving unit is arranged outside the connecting channel. Through the above improvements, ultrafine powder is prevented from entering the driving unit and causing damage to the driving unit, thereby increasing the service life of the driving unit.

[0012] Preferably, the dust bag can be expanded in the dust collection bucket. Through the above improvements, the dust bag is made of elastic material so that it can expand as the ultrafine powder is placed, thereby collecting more ultrafine powder.

[0013] Preferably, a plurality of air outlets are formed on the dust collecting bucket. Through the above improvements, as the dust collecting bag expands, the dust collecting bag will fill up the entire dust collecting bucket, and the air inside can be discharged from the air outlets.

[0014] Preferably, the exhaust pipe is connected to an oxygen controller. Through the above improvements, the oxygen content in the powder barrel can be monitored at all times during the powder discharge process to ensure the safety of the ultrafine powder discharge.

[0015] Preferably, the powder inlet end of the powder storage barrel is provided with a nitrogen inlet for nitrogen to enter. Through the above improvements, during the process of releasing the ultrafine powder, nitrogen is continuously input into the powder barrel with a slight positive pressure, so that the ultrafine powder enters the dust removal structure.

[0016] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0017] By connecting the powder storage barrel to the dust removal structure, most of the ultrafine powder produced by the air flow mill is discharged into the powder storage barrel, and another part of the ultrafine powder moves to the dust removal structure with the airflow. The ultrafine powder discharged with the airflow will first pass through the water flow section for adsorption and filtration, so that the larger particles in the ultrafine powder are adsorbed in the water flow section, and the powder suction component introduces the smaller particles in the remaining ultrafine powder into the collection section for collection, so that all the ultrafine powder is collected, avoiding the emission of ultrafine powder into the air to cause environmental pollution and harm to employees' bodies.

[0020] 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.

[0021] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0022] like Figure 1 As shown, a system for cleaning, exhausting oxygen and removing dust from an ultrafine powder of an air flow mill comprises a powder storage barrel 1 connected to an air flow mill device 3, wherein the powder storage barrel 1 is connected to a dust removal structure 2, and the dust removal structure 2 comprises a water flow portion 101 for adsorbing dust, a collecting portion 102 for collecting dust, and a connecting channel 103 for connecting the water flow portion 101 and the collecting portion 102, and a powder suction component 104 for introducing fine dust in the water flow portion 101 into the collecting portion 102 is arranged in the connecting channel 103.

[0023] During the operation of the entire oxygen exhaust and dust removal system, the air flow mill first injects the generated ultrafine powder into the powder storage barrel 1, and the powder storage barrel 1 is connected to the dust removal structure 2. Most of the ultrafine powder will be directly retained in the powder storage barrel 1, and some other ultrafine powder will enter the dust removal structure 2. The ultrafine powder discharged with the gas will first pass through the water flow section 101 for adsorption and filtration, so that the larger particles in the ultrafine powder are adsorbed in the water flow section 101, and the powder suction component 104 introduces the smaller particles of the remaining ultrafine powder into the collection section 102 for collection, so that all the ultrafine powder is collected, avoiding the emission of ultrafine powder into the air to cause environmental pollution and physical damage to employees.

[0024] like Figure 1 As shown, further explanation of the implementation method of the water flow part 101 in this embodiment is provided, wherein the water flow part 101 includes a water storage barrel 201, and one end cover of the connecting channel 103 is provided on the water storage barrel 201 to isolate the water storage barrel 201 from the external space, and an exhaust pipe 202 is provided on the powder storage barrel 1, and the exhaust pipe 202 is connected to the water storage barrel 201. The ultrafine powder discharged from the powder storage barrel 1 with the airflow will first enter the water storage barrel 201, wherein the dust with relatively larger particles in the ultrafine powder will be adsorbed by water when passing through the water storage barrel 201 and remain in the water. In addition, the remaining ultrafine powder with a smaller size will float out of the water with the airflow and continue to be collected by the collecting part 102, thereby realizing the recovery of the ultrafine powder.

[0025] Among them, the powder inlet end of the powder storage barrel 1 is provided with a nitrogen inlet 204 for nitrogen to enter, and nitrogen can be injected through the nitrogen inlet 204. During the process of releasing ultrafine powder, nitrogen maintains a slight positive pressure and continuously inputs into the powder barrel, so that the gas in the powder storage barrel 1 carries the ultrafine powder into the dust removal structure 2.

[0026] In addition, the exhaust pipe 202 is connected to an oxygen controller 203, which can monitor the oxygen content in the powder barrel at all times during the powder discharge process to ensure safety during the ultrafine powder discharge process.

[0027] Preferably, the water flow portion 101 is detachably connected to the connecting channel 103, and a first connecting protrusion 205 is formed on the connecting channel 103, and a second connecting protrusion 206 connected to the first connecting protrusion 205 is formed on the water flow portion 101. The first connecting protrusion 205 and the second connecting protrusion 206 cooperate with each other to facilitate the disassembly of the water flow portion 101, so as to facilitate the replacement of water in the water flow portion 101 and the cleaning of the water flow portion 101, and to facilitate the operator to carry out subsequent maintenance.

[0028] like Figure 1As shown, further explanation of the implementation method of the collecting part 102 in this embodiment is provided, wherein the collecting part 102 includes a dust collecting bucket 301, and a dust collecting bag 302 arranged in the dust collecting bucket 301, and the dust collecting bag 302 is connected to the connecting channel 103. After the relatively larger dust particles in the ultrafine powder are adsorbed by the water passing part 101, the remaining ultrafine powder with a smaller size will enter the dust collecting bag 302 under the action of the powder suction component 104, thereby realizing the collection of the ultrafine powder.

[0029] Furthermore, the dust bag 302 is made of elastic material, so that the dust bag 302 can expand in the dust bin 301, thereby collecting more ultrafine powder.

[0030] In addition, a plurality of air outlets 303 are formed on the dust collecting barrel 301 . As the dust collecting bag 302 expands, the dust collecting bag 302 will fill up the entire dust collecting barrel 301 , and the air inside can be discharged from the air outlets 303 .

[0031] As a further explanation of the implementation method of the powder suction component 104 in this embodiment, the powder suction component 104 includes a powder suction fan blade 401 rotated in the connecting channel 103, and a driving unit 402 for driving the powder suction fan blade 401 to rotate. When the driving unit 402 drives the powder suction fan blade 401 to rotate, the powder suction fan blade 401 will move the smaller ultrafine powder toward the collecting part 102, so that the remaining ultrafine powder is collected in the collecting part 102, thereby greatly improving the dust removal effect.

[0032] Preferably, the powder suction blades 401 are horizontally arranged in the connecting channel 103 , and the driving unit 402 is arranged outside the connecting channel 103 , so as to prevent ultrafine powder from entering the driving unit 402 and causing damage to the driving unit 402 , thereby improving the service life of the driving unit 402 .

[0033] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
