Description

Technical Field

[0001] The present application relates to the technical field of air purification devices, and in particular to a purification air supply unit for a workshop. Background Art

[0002] The workshop purification air supply unit is an air purification equipment specially designed for industrial clean rooms. Its main function is to filter particles in the air through a built-in high-efficiency filter, thereby providing clean air and ensuring that the air cleanliness in the workshop meets specific standards.

[0003] After searching, the Chinese patent authorization number CN213810969U discloses an air supply vent for a pharmaceutical factory cleanroom, which relates to the technical field of air purification devices. Although the device achieves the effect of sufficient filtration, disinfection and sterilization by setting a liquid inlet pipe, a microporous atomization sheet, a coarse-effect filter device and a high-efficiency filter plate to solve the dust-free and sterile environment required for the pharmaceutical factory cleanroom, when the air supply vent is supplying air, when the external air temperature is high and the indoor temperature is low, the temperature difference of the air flow entering the room from the air supply vent is large, which can easily cause the indoor air flow to fluctuate between hot and cold, and then easily cause human discomfort.

[0004] After searching, the Chinese patent authorization number CN217330083U discloses an air supply system for a clean room. The outdoor wind enters the sleeve through the filter.

[0016] Compared with the prior art, the beneficial effects of this application are:

[0017] (1) This kind of workshop purification air supply unit, the excess indoor gas is effectively transported to the interior of the heat exchange chamber through the exhaust fan and the first pipe. In this process, after entering the heat exchange chamber, the cold air in the room contacts and cools the conical cavity, and then is discharged through the second pipe. The introduction of the positive pressure fan allows the external air to enter the three-way pipe through the air inlet pipe under its action, and finally flow to the conical cavity inside the heat exchange chamber, where the external hot air exchanges heat with the cooled conical cavity. This process effectively reduces the temperature difference between the airflow entering the room and the indoor temperature.

[0018] (2) A purification air supply unit for a workshop, in which external air is introduced through an air inlet duct and pressurized by a positive pressure fan, and then enters the conical cavity inside the heat exchange chamber. The airflow enters along the inner wall of the conical cavity in a tangential direction, forming a spiral downward airflow movement. At the same time, gravity is also guiding the dust particles to settle downward. During the spiral movement of the inner wall of the conical cavity, the dust particles are affected by the combined effects of centrifugal force and gravity, causing the particles to move downward along the inner wall of the cavity and finally fall into the collection bin for collection. This process effectively separates dust from airflow without the use of traditional filters, thereby reducing the impact on the air circulation rate and ensuring the stable air output of the air supply unit.

During the flow of the airflow, the second electrode plate is connected to an external negative power supply, so that the second electrode plate will generate corona discharge, ionizing the air molecules flowing between the first electrode plate and the second electrode plate, thereby forming a large number of electrons and positive ions. The electrons move toward the first electrode plate under the action of the electric field force, collide with the dust particles and make the dust particles negatively charged, thereby realizing the charging effect on the dust. The negatively charged dust particles move toward the positive electrode under the action of the electric field force and adhere to the positively charged The first electrode plate allows tiny dust particles in the air to be collected by the first electrode plate, thereby further purifying the dust in the air. The driving motor drives the transmission gear to rotate, and the transmission gear drives the threaded rod to rotate through the driven gear, and then the threaded rod drives the slider to move horizontally. When the slider moves, it pushes the dust collected on the surface of the first electrode plate to move, and then the dust moves to one end of the first electrode plate and falls into the discharge trough. The inclined structure of the discharge trough allows the dust particles inside the discharge trough to slide into the collection bin for collection, which is conducive to achieving the self-cleaning effect of the surfaces of the first electrode plate and the second electrode plate.

[0020] (4) This kind of workshop purification air supply unit, when the indoor air intake volume is greater than the indoor air outlet volume, in order to avoid excessive indoor air pressure, the excess air can push the baffle under the action of air pressure, thereby entering the negative pressure chamber, and then being discharged through the exhaust duct inside the negative pressure chamber, which is beneficial to balancing the indoor and outdoor air pressure difference. By sliding the slider and then tightening the fixing bolts, the position of the slider can be adjusted, and then the tension of the spring can be adjusted, so that the pressure of the excess air in the room to push open the baffle can be adjusted, which is beneficial to adjusting the maximum indoor air pressure.
