Description

Technical Field

[0001] The invention relates to the technical field of dust removal, in particular to an indoor dust removal device. Background Art

[0002] In dusty weather conditions, such as smog, there is often a lot of dust indoors, which affects people's respiratory health.

[0003] For example, a Chinese patent with publication number "CN103933817A" discloses "a wet indoor dust removal device", whose main structure includes a shell, an air inlet pipe and an exhaust pipe are provided on the shell, and a liquid phase maze is provided in the shell, the air inlet of the liquid phase maze is connected to the air inlet pipe, and the air outlet is connected to the exhaust pipe; the liquid phase maze is at least partially immersed in the liquid. The liquid phase maze is composed of a plurality of horizontally arranged partitions arranged in an interlaced manner, and a bristle layer is provided at least on the water-facing surface of the partition. The wet indoor dust removal device adopts a wet adsorption method and cooperates with the structure of the liquid phase maze to effectively adsorb dust in the air and reduce the inhalable particulate matter in the room. In particular, the structure of the liquid phase maze prolongs the contact time between air and liquid, which plays a good dust removal role.

[0004] From the above description, we can know that when the wet indoor dust removal device is actually working, it relies on the adsorption and dissolution effect of liquid on dust to achieve effective dust removal of indoor gas. However, since the solubility saturation of dust in the liquid in the equipment is relatively limited, a large amount of dust will cause the liquid and dust to dissolve into a fluid after dissolution, and the equipment cannot produce a timely discharge effect on solid dust, resulting in a relatively short single use time of the equipment.

In addition, the device can cause the dust in the liquid to produce a timely downward accumulation and transportation effect, so that the accumulated dust can be discharged in time, and the sludge formed by sewage and dust can be discharged separately, thereby realizing the separate discharge of waste materials, so that the equipment can work continuously, thereby solving the above-mentioned technical problems.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the size of the air inlet 7 needs to meet the size required for the gas and liquid to flow simultaneously.

[0023] To achieve mixing between gas and liquid, see Figure 1 , Figure 2 , Figure 4 and Figure 5 , it is necessary to set a rotating driven mechanism 12, which is provided with a No. 1 hollow rotating column 121 capable of discharging liquid in the form of atomization to the surroundings, a No. 1 spiral impeller 123 capable of generating a downward conveying force on the surrounding medium when rotating, and a wing-shaped fan blade 125 capable of generating an upward airflow when rotating. During the rotation of the wing-shaped fan blade 125, the dusty gas from the outside will enter from the air inlet 7 and flow upward. At this time, the liquid will continuously enter the interior of the No. 1 liquid flow chamber 128, and finally pass through each liquid atomizing nozzle 1210 It is discharged to the surroundings in the form of atomization. When the atomized liquid meets the dust in the air, the two will merge.

In order to realize the directional flow of the liquid, it is necessary to make the structural radius of the liquid limiting flow cavity 136 smaller than the structural radius of the No. 2 liquid flow cavity 133, and the structural radius of the liquid limiting flow cavity 136 is larger than the structural radius of the No. 2 shaft mounting hole 137.

The continuous rotation of the first spiral impeller 123 will cause the sludge to generate a force on the insertion column structure 148. When the force is greater than the elastic strength of the spiral spring 1412, the insertion column structure 148 will move downward, and the sludge The sludge will accumulate between the inserted column structure 148 and the first spiral impeller 123. Part of the sludge will push the inserted column structure 148 to move downward, but the accumulated sludge will not cause sewage leakage. When the amount of sludge accumulation reaches a certain level, rotating the rotating ring 146 will cause the inserted column structure 148 to rotate, so that the accumulated sludge will disintegrate under the outward force and fall to the surrounding. At this time, the elasticity of the spiral spring 1412 will drive the inserted column structure 148 to be inserted into the inside of the sludge conveying hole 6 in time, thereby realizing the separate discharge function of the sludge.

The rod body of the longitudinal telescopic rod 1410 corresponds to the rod body through-hole 149, and a top limit plate 1411 is fixedly installed on the top. The longitudinal telescopic rod 1410 is sleeved with a compressed coil spring 1412 on the outer periphery of the rod body between the top limit plate 1411 and the upper limit plate 141.

[0029] The specific working principle of the present invention is to place the device in an indoor space that needs to be dusted, and then connect the liquid injection channel 134 with the liquid discharge port of a storage tank storing dust-reducing liquid through a pipeline, and the liquid in the storage tank is in a state of constantly moving toward the liquid injection channel 134, and then start the drive motor 8; The rotor of the driving motor 8 drives the main pulley 9 to rotate, and the main pulley 9 drives the secondary pulley 1310 to rotate through the belt 10, and the secondary pulley 1310 drives the second hollow rotating column 1311 to rotate, and the second hollow rotating column 1311 drives the second spiral impeller 1312 to rotate, and the second spiral impeller 1312 will cause the liquid from the liquid injection channel 134 to be compressed downward when rotating; When the wing-shaped blades 125 rotate, the dusty gas from the outside will enter from the air inlet 7 and flow upward. At this time, the liquid will continue to enter the interior of the No. 1 liquid flow chamber 128, and will eventually be discharged to the surroundings in the form of atomization through each liquid atomization nozzle 1210. When the atomized liquid encounters dust in the air, the two will merge. When the gravity after the two contact is greater than the force of the gas on the two, the two will be deposited inside the funnel cavity 4, and the rotating No. 1 spiral impeller 123 will cause the sludge formed by the dust and the liquid to be stratified. The sludge will dock and be compressed inside the sludge conveying hole 6, and the liquid will be in the upper layer of the sludge. Finally, the sludge formed by the dust will be discharged downward through the sludge conveying hole 6, and the liquid will eventually overflow through the air inlet 7 due to continuous deposition; When it is observed that the amount of sludge accumulation reaches a certain level, rotating the rotating ring 146 will cause the inserted column structure 148 to rotate, so that the accumulated sludge will disintegrate under the outward force and fall to the surrounding. At this time, the elasticity of the coil spring 1412 will drive the inserted column structure 148 to be inserted into the inside of the sludge conveying hole 6 in time, thereby achieving a sustainable working state.
