Description

Technical Field

[0001] This application belongs to the field of lithium battery drying, and specifically relates to a shock absorption and noise reduction mechanism for a fan. Background Art

[0002] Lithium-ion batteries have advantages such as high energy density and long cycle life, which promote the leapfrog development of emerging industries such as new energy vehicles and are applied to national strategic fields such as satellites and drones. The electrode is a key component of the lithium-ion battery and is an important link for converting chemical energy into electrical energy. The battery electrode consists of a positive electrode and a negative electrode. The positive electrode corresponds to the oxidation reaction, and the negative electrode corresponds to the reduction reaction. The positive electrode material has strong water absorption and is the main source of the water content in the battery. Excessive water will cause damage to the structure of the electrode material, affect the electrochemical performance, and may even cause safety problems such as battery short circuit, swelling or explosion. Therefore, controlling the water content of the electrode is crucial for ensuring the performance and safety of the battery. The electrode is dried at a high temperature. A relatively high drying temperature can effectively remove water. Forced convection heating is the main heating method at present. Forced convection heating is achieved through a forced air system. The entire forced air system mainly includes a fan, an air heating device, and a drying device. The fan is used to push air to flow in a specific cavity. After the air is heated by the heating device, hot air is formed. The hot air is transported to the drying device to dry the electrode. The fan is a key device that constitutes the forced air system. The fan provides driving force for the air to achieve stable air flow. In the forced air system of the prior art, after the fan is connected to other devices, the fan is in a suspended state. During the operation of a high-power fan, intense vibration and noise are generated, causing resonance of the entire forced air system and affecting the normal operation of the forced air system, becoming a potential hazard point of the entire forced air system. Summary of the Utility Model

[0003] Aiming at the problems existing in the prior art, the utility model provides a shock absorption and noise reduction mechanism for a fan to avoid the resonance phenomenon caused by the operation of the fan itself and achieve the purpose of shock absorption and noise reduction.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A shock absorption and noise reduction mechanism for a fan, which includes a frame fixed below the fan and used to support the fan and a hose connected to the air inlet of the fan. The frame is a frame structure. The port of the hose far from the fan is connected to the air outlet of the air collection device of the forced air system. A plurality of buffer members for reducing vibration are provided between the frame and the fan. A plurality of feet for adjusting the height of the frame and independently adjusting each other are provided at the bottom of the frame.

[0006] Furthermore, a support plate is fixed on the top of the frame. A notch for the motor of the fan to pass through is opened on the support plate. A plurality of fixing holes I are provided around the notch on the support plate.

[0007] Further, the buffer is fixed above the support plate and coaxial with the fixing hole. The buffer is a cylindrical PU buffer pad, and an axial through hole is formed in the buffer. The position and number of the buffers are the same as those of the fixing hole 1.

[0008] Further, a plurality of fixing holes 2 are provided on the bottom surface of the fan. The distribution positions of the fixing holes 2 correspond to those of the fixing hole 1, and the fixing hole 1, the axial through hole and the fixing hole 2 are coaxial.

[0009] Further, the two ports of the hose have different shapes.

[0010] Further, the hose is connected to the fan and the air collecting device through flanges respectively. Flange plates 1 and 2 are provided at both ends of the hose. The shapes of the flange plates 1 and 2 are adapted to the port shapes of the hose. A plurality of through holes 1 for connecting with the fan and the air collecting device are formed on both the flange plates 1 and 2.

[0011] Further, the frame includes a plurality of columns and reinforcing bars connected between the columns. A plugging plate for closing the column opening is provided at the bottom end of the column, and a through hole 2 is formed in the plugging plate.

[0012] Further, the support leg includes a threaded rod extending into the through hole 2 and a support connected to the bottom end of the threaded rod. Two nuts 2 are provided on the threaded rod and are arranged one above the other.

[0014] Advantages of the present utility model

[0015] A fan shock absorption and noise reduction mechanism of the present utility model provides stable support for the fan by setting a frame which is not connected to other devices of the air transportation system, is independent of the air transportation system, and is installed in a separated manner from the air transportation system. The fan is connected to the air collecting device through a hose, and a plurality of buffers are arranged between the frame and the fan. The buffers are cylindrical PU buffer pads. The hose connection can avoid resonance caused by rigid connection, and the elastic deformation of the buffers absorbs and disperses the vibration generated during the operation of the fan, reducing or eliminating impact or vibration, so as to achieve the effect of shock absorption and noise reduction. By setting support legs to adapt to different ground conditions or installation requirements, the fan bracket fixing seat used in cooperation with the support legs fixes the frame to the ground to ensure the stability of the fan operation.

[0029] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0030] As Figure 1-8 shown, a fan shock absorption and noise reduction mechanism includes a frame 2 fixed below the fan 1 and used to support the fan 1, and a hose 3 connected to the air inlet of the fan 1. The frame 2 is a frame structure. The port of the hose 3 far from the fan 1 is connected to the air outlet of the air collecting device of the air transportation system. A plurality of buffer members 4 for reducing vibration are provided between the frame 2 and the fan 1. A plurality of feet 5 for adjusting the height of the frame 2 and independently adjusting each other are provided at the bottom of the frame 2.

[0031] As Figure 4 shown, a support plate 6 is fixed on the top of the frame 2. A notch 7 for the motor 11 of the fan 1 to pass through is opened on the support plate 6. A plurality of first fixing holes are provided around the notch 7 on the support plate 6.

[0032] As Figure 4 shown, the buffer member 4 is fixed above the support plate 6 and is coaxial with the first fixing hole. The buffer member 4 is a cylindrical PU buffer pad. An axial through hole 8 is opened on the buffer member 4. The position and number of the buffer members 4 are the same as the position and number of the first fixing holes. The buffer member 4 can be, for example, 4 - 8.

[0033] As Figure 2 and Figure 7 shown, there are multiple second fixing holes 102 on the bottom surface 1O1 of the fan 1. The distribution positions of the second fixing holes 102 correspond to those of the first fixing holes. The first fixing holes, the axial through holes 8 and the second fixing holes 102 are coaxial. Bolts pass through the second fixing holes 102, the axial through holes 8 and the first fixing holes from top to bottom and then are screwed into the first nuts to fix the fan 1 on the frame 2. The vibration generated during the operation of the fan 1 is absorbed and dispersed through the elastic deformation of the buffer member 4, thereby reducing or eliminating the impact or vibration, reducing the noise and reducing the wear of the fan 1.

[0034] As Figure 8 shown, the two ports of the hose 3 have different shapes. The port connected to the air inlet of the fan 1 is circular, and the port connected to the air outlet of the air collecting device is rectangular. The fan 1 is connected to the air collecting device through the hose 3 to avoid resonance caused by rigid connection and achieve the purpose of shock absorption and noise reduction.

[0035] As Figure 1 , Figure 2 , Figure 3 and Figure 8 shown, the hose 3 is connected to the fan 1 and the air collecting device through flanges respectively. Flange plates one 901 and flange plates two 902 are provided at both ends of the hose 3. The shapes of the flange plates one 901 and flange plates two 902 are adapted to the port shapes of the hose 3. The flange plates one 901 are rectangular, and the flange plates two 902 are circular. Multiple first through holes 903 for connecting to the fan 1 and the air collecting device are opened on the flange plates one 901 and flange plates two 902.

[0036] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the frame 2 includes multiple columns 201 and reinforcing bars 202 connected between the columns 201. For example, there can be four columns 201, and the four columns 201 are distributed in a square shape. The columns 201 can be, for example, hollow square steel pipes. A sealing plate for closing the opening of the column 201 is provided at the bottom end of the column 201, and a second through hole is opened on the sealing plate. The reinforcing bars 202 are, for example, arranged at the top, middle or bottom positions of the columns 201 from top to bottom to enhance the stability of the frame 2. The frame 2 is not connected to other equipment of the air transportation system and is independent of the air transportation system, and is installed in a separated manner from the air transportation system.

[0037] As Figure 4 and Figure 5As shown, the support leg 5 includes a threaded rod 501 extending into the second through hole and a support 502 connected to the bottom end of the threaded rod 501. There are two nuts 503 on the threaded rod 501, which are arranged one above the other. The two nuts 503 can effectively prevent the nuts 503 from loosening. By adjusting the length of the threaded rod 501 entering the second through hole respectively, the frame 2 can be stably placed on the ground. Then, turn the upper nut 503 to be close to the sealing plate, and turn the lower nut 503 to be close to the upper nut 503, so as to set the support leg 5 to adapt to different ground conditions or installation requirements.

[0038] As Figure 4 , Figure 5 and Figure 6 As shown, a blower support fixing seat 10 is provided on one side of the support leg 5. The blower support fixing seat 10 is higher than the support leg 5. The blower support fixing seat 10 includes a side plate 1001 connected to the column 201, a bottom plate 1002 connected to the lower edge of the side plate 1001, and a rib plate 1003 connected to both the side plate 1001 and the bottom plate 1002. Through holes 1004 are respectively formed on the bottom plates 1002 on both sides of the rib plate 1003. After the support leg 5 is adjusted to a suitable height, pointed screws or studs pass through the through holes 1004 and are nailed into the ground to fix the frame 2 to the ground and ensure the stability of the operation of the blower 1.

[0039] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of this invention patent shall be subject to the appended claims.
