Air volume adjustable plenum chamber, air volume adjustable drying room and operation method

Abstract

The invention provides an air volume adjustable plenum chamber and an air volume adjustable drying room. An adjusting device comprises two mounting plates, a clamping frame and a baffle, the clamping frame and the baffle are arranged between the two mounting plates, the clamping frame comprises a first limiting piece and second limiting pieces, and the two ends of the first limiting piece are connected with one ends of the two second limiting pieces separately. When the baffle moves from one end of the first limiting piece to the other end, the baffle gets close to or away from the first limiting piece. The drying room comprises a fan, an air duct, rollers and the plenum chamber, wherein the plenum chamber is connected to the air duct in parallel. According to the air volume adjustable plenum chamber and the air volume adjustable drying room, through the operation method, the baffle is adjusted to the proper position in the clamping frame, the communication area between the plenum chamber and the air duct is changed, the air volume difference in all the plenum chambers is improved, and the air pressure distribution uniformity of air outlet holes is improved; and meanwhile, an excessive wind pressure reduction method is avoided, the production cost is saved, the energy consumption is reduced, and the production efficiency and quality of products are improved.

Description

technical field [0001] The invention relates to the field of static pressure boxes, in particular to a static pressure box with adjustable air volume, a drying room and an operation method. Background technique [0002] The separator is an important part of the lithium-ion battery, which can provide lithium-ion transmission channels, and prevent the short circuit of the positive and negative contacts, which is very important for the safety of the lithium-ion battery. In the production process of the lithium battery diaphragm, it needs to be dried in the drying room, and the air of a certain temperature is blown to the diaphragm through the static pressure box. [0003] However, when the fan is blowing air, the high-pressure air will first fill the plenum away from the tuyere along the air duct, and then gradually enter the plenum close to the tuyere from far to near, so that the internal air volume of the plenum in different positions will vary from The problem of uneven ai...

Problems solved by technology

[0003] However, when the fan is blowing air, the high-pressure air will first fill the plenum away from the tuyere along the air duct, and then gradually enter the plenum close to the tuyere from far to near, so that the internal air volume of the plenum in different positions will vary from The problem of uneven air volume from the far end of the air inlet to the near end of the air inlet. When the pore diameter and hole density distribution of the air outlet holes on the surface of the plenum box is uniform, the wind pressure distribution of the air outlet holes on the surface of the different plenum boxes will also appear. The tendency of the static pressure box to decrease from the far end of the air inlet to the near end of the air inlet causes the difference in wind pressure inside the drying room and the disorder of the wind field
