Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a purification device for a novel combined air conditioning unit. Background Art

[0002] Combined air conditioner is an air conditioning unit composed of a combination of multi-functional section purifiers. It is commonly used in air purification systems of various clean workshops, such as industrial electronics factories, precision machinery manufacturing plants, textile workshops and many other occasions.

[0003] During the use of the combined air conditioner, since the outside air is cooled by the outdoor unit and then discharged into the room, in order to prevent dust from entering the room, a filter is set at the air inlet of the outdoor unit. However, although the existing filter can filter some dust, some dust will still enter the outdoor unit and then enter the workshop with the air flow, causing air pollution in the workshop. In addition, during long-term use, dust will also adhere to the fan blades, so that when people replace the filter later, they also need to clean the fan, which is more troublesome. At the same time, since some workshops need to be kept dry, some existing outdoor units are equipped with dehumidification mechanisms to dehumidify the gas entering the workshop. Since most of the existing dehumidification uses dehumidifiers to adsorb moisture, the dehumidifier that first contacts the gas adsorbs more moisture, and the side far from the air outlet adsorbs less moisture, so that each time the dehumidifier is replaced, a part of the dehumidifier cannot fully reach its maximum absorption level, resulting in waste of dehumidifier. Therefore, it is necessary to design a new type of purification device for combined air conditioning units to solve the above problems. Summary of the invention

Sealing blocks 40 are slidably connected in the two annular grooves, and the adjacent sides of the two sealing blocks 40 and the second electromagnets 41 are elastically connected through a second spring. Sealing rings are provided on the opposite sides of the two sealing blocks 40 to ensure the sealing between the cylinder 45 and the air outlet pipe 20 and the cross pipe 39. A timer and a controller are provided. When the running time reaches the timing time of the timer, the timer will transmit a signal to the controller, and the controller controls the pneumatic rod 44 to contract first and then stretch, and at the same time, the first electromagnet 29 and the second electromagnet 41 are energized for a period of time.

[0023] The functional principle of the present invention can be explained through the following operation mode: first, the outlet pipe 20 is connected to the main machine in the factory, and then the driving motor 22 is controlled to operate, so that the fan 23 rotates, so that the external air enters the housing 1 through the filter, and then is injected into the factory through the outlet pipe 20. When the air conditioning unit is running, the electrostatic generator 2 will be synchronously operated. Since the conductive rod 18 located at the front side is in contact with the two conductive blocks 19 at this time, the electrostatic rod 9 located at the top is energized and operated; When the electrostatic rod 9 is powered on, static electricity will be generated on the electrostatic rod 9. At this time, the gas entering the housing 1 will be initially filtered through the filter, and some fine dust will enter the housing 1. According to the characteristic that static electricity attracts small particles, the fine dust in the air will be adsorbed on the electrostatic rod 9 located above. When the fan 23 is running, the incomplete gear 37 will rotate. When the incomplete gear 37 is meshed with the first gear 36, the first gear 36 will drive the thick rod 35 and the disc 7 located above to rotate, thereby causing the electrostatic rod 9 located above to rotate. When the incomplete gear 37 is not meshed with the first gear 36, the thick rod 35 drives the disc 7 and the electrostatic rod 9 to rotate in the opposite direction under the action of the torsion spring 34, so that the electrostatic rod 9 can more comprehensively absorb the dust in the gas entering the housing 1. After a period of time, when the timer reaches the running time, the timer transmits a signal to the controller, and the controller controls the pneumatic rod 44 to contract first and then stretch, and controls the first electromagnet 29 and the second electromagnet 41 to be energized for a period of time. When the first electromagnet 29 is energized for a period of time, it will generate an attractive force on the corresponding L-shaped rod 31, so that the two L-shaped rods 31 move right, so that the two L-shaped rods 31 are away from the electrostatic rod 9 located below; When the pneumatic rod 44 contracts, the moving block 26 drives the rack 17 to move backward, so that the second gear 43 drives the switching rod 16 to rotate, so that the positions of the two electrostatic rods 9 are exchanged. When the switching rod 16 rotates, the two conductive rods 18 are separated from the conductive block 19, so that the static electricity on the electrostatic rods 9 will slowly dissipate. When the positions of the two electrostatic rods 9 are exchanged, the electrostatic rod 9 that rotates to the upper side is powered on, and the dust on the electrostatic rod 9 that rotates to the lower side will slowly dissipate, so that the dust on the electrostatic rod 9 will fall to the inner bottom of the shell 1 (a collection box can be placed at the inner bottom of the shell 1, so that the fallen dust can fall into the collection box, which is convenient for subsequent staff to clean up); When the pneumatic rod 44 contracts, the moving block 26 drives the rack 17 to move forward. Since a one-way bearing is provided between the second gear 43 and the switching rod 16, the rotation of the second gear 43 will not drive the switching rod 16 to rotate. After a period of time, the first electromagnet 29 is powered off, so that the two L-shaped rods 31 move back, so that the multiple bristles 32 move to the upper and lower sides of the electrostatic rod 9. When the driving motor 22 is running, the second bevel gear 38 drives the rotating rod 4 to rotate, and then the first transmission assembly 3 and the third transmission assembly 27 drive the two screw rods 5 to rotate, so that the two sliders 28 drive the multiple bristles 32 to move forward and backward, so as to clean the electrostatic rod 9 rotated to the bottom; The gas entering the housing 1 will enter the cylinder 45 through the transverse pipe 39, and then be injected into the main unit through the outlet pipe 20, and finally injected into the workshop. At this time, the activated carbon in the cylinder 45 can dehumidify the gas, so that the gas entering the workshop remains dry. After the two second electromagnets 41 are energized, an attractive force is generated on the two sealing blocks 40, so that the two sealing blocks 40 move relative to each other, so that the two sealing blocks 40 are away from the air outlet pipe 20 and the cross pipe 39. When the switching rod 16 rotates, the transmission rod 12 is driven to rotate, thereby driving the cross rod 13 to rotate through the second transmission assembly 11, so that the cylinder 45 rotates 180 degrees, and then the positions of the activated carbons on the left and right sides of the cylinder 45 are exchanged, thereby ensuring that each activated carbon can fully exert its adsorption performance; After a period of time, the second electromagnet 41 will be powered off. At this time, under the elastic action of the second spring, the two sealing blocks 40 will move away from each other, so that the two sealing blocks 40 are tightly squeezed on the adjacent sides of the outlet pipe 20 and the cross pipe 39 again, so that the gas in the shell 1 enters the main unit through the cross pipe 39, the cylinder 45 and the outlet pipe 20, and then is injected into the workshop.

[0024] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
