Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to an equipment microenvironment purification system. Background Art

[0002] The new energy industry's production equipment generally has the problem of ineffective control of micro-environment dust. Traditional equipment processes do not have a reasonable flow field design in the micro-environment during operation. Dust-containing fluids acting on the surface of workpieces or components will form serious turbulence, and dust will float around in the equipment and accumulate in every corner of the equipment, and cannot be effectively purified and removed by dust removal equipment; at the same time, it is easy to stay on the surface of high-speed moving pole pieces. The high-speed relative movement of the pole pieces will superimpose the electrostatic field force on the dust, making the dust more stubborn and difficult to remove; for example, some battery pole piece processing equipment (such as die-cutting machines, winding machines, cutting and stacking machines, ultrasonic welding, shelling machines, coating machines, pre-welding machines, full welding equipment, etc.), if the negative impact of micro-environment dust cannot be removed, dust will easily adhere to the inside of the battery cell, causing battery self-discharge, affecting the consistency and safety performance of the battery and battery life, and in severe cases, leading to bulging, combustion, explosion, etc. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] See also Figures 1 to 4 , a device micro-environment purification system includes a dust removal filter 1 and a device cover 2 mounted on the device, an air inlet is provided on the upper side of the device cover 2, and a return air outlet 4 is provided at the bottom of the device; a guide plate 3 is provided at the bottom of the device above the return air outlet 4, and a plurality of return air holes for guiding the direction of airflow are provided on the guide plate 3, and a processing station 8 of the device is located between the air inlet and the guide plate 3, and an ion generator is installed at the air inlet on the device cover 2 (not shown in the figure for existing equipment); the return air outlet 4 is connected to the dust suction port of the dust removal filter 1. An air inlet is reasonably set on the equipment cover 2, and an ion generator is installed at the air inlet, so that the air blown into the equipment has the function of eliminating static electricity, forming local space ionization, effectively eliminating dust static electricity, so that the dust can be easily peeled off and sucked away, and a guide plate 3 is provided between the return air inlet 4 and the equipment processing station 8, and a return air hole is provided on the guide plate 3. In this way, the air enters from the air inlet and passes through the processing station 8 into each return air hole, forming a relatively stable air directional fluid (reducing turbulence), so that the dust generated by the processing station 8 during processing can be carried to the return air hole and the return air inlet 4 along the flow direction of the air and finally collected in the dust removal filter 1, significantly reducing the dust turbulence phenomenon and reducing the probability of entering the product and accumulating in the corners of the equipment.

[0020] See also Figure 1 、 Figure 4 Preferably, a plurality of return air holes are arranged at intervals on the guide plate 3, and the return air holes are arranged below the outer edge of the processing station 8 of the equipment. By arranging the return air holes below the outer edge of the processing station 8, the airflow blown in by the air inlet blows up the dust on the surfaces of the components of the processing station 8, and then, under the suction provided by the return air holes, the airflow forms a stable airflow from the edge of the processing station 8 to the return air holes, so that the dust can be stably carried into the return air holes by the airflow and then sucked into the dust removal filter 1 through the return air port 4.

[0021] See also Figures 1 to 3Preferably, a filter fan 5 is further provided at the air inlet, and the air outside the equipment cover 2 is blown into the equipment through the filter fan 5 and the ion generator in sequence. A filter fan 5 is provided at the air inlet to filter the air entering the equipment, so that the air entering the equipment cover 2 is exhausted, and external dust is prevented from entering the processed products, so as to reduce dust during the product processing. The preferred filter fan 5 is an FFU unit. The ion generator is integrated into the filter fan 5, and the preferred one may be the FFU global static removal and dust removal KU-50. The FFU unit can achieve ten thousand-level wind speed adjustment, and thus can achieve dynamic ten thousand-level purification of the environment of the equipment cover 2.

[0022] See also Figures 1 to 3 Preferably, the device cover 2 is provided with a plurality of air inlets. Providing a plurality of air inlets can increase the air intake volume and help reduce the dust collection resistance of the dust removal filter 1.

[0023] See also Figures 1 to 3 Preferably, a dust collecting pipe 6 is connected between the dust suction port of the dust removal filter 1 and the return air port 4. It is convenient to install the dust removal filter 1 at any position in the workshop as needed.

[0024] See also Figures 1 to 3 Preferably, the dust collection duct 6 is connected to the return air outlet 4 of multiple devices. One dust removal filter 1 can be used to remove dust from multiple devices, reducing equipment procurement costs. A single dust removal filter can also be used to remove dust from a single device, but the invention is not limited thereto.

[0025] See also Figures 1 to 3 Preferably, a funnel-shaped connector 7 is provided at the lower end of the device. The small end of the connector 7 opens to the return air port 4 and is connected to the dust collection duct 6. The large end of the connector 7 is fixed to the bottom surface of the device and communicates with the return air hole. This facilitates the connection between the return air hole and the dust collection duct 6 to achieve negative pressure dust collection.

[0026] See also Figures 1 to 3 Preferably, the exhaust port of the dust removal filter 1 is connected to the indoor or outdoor. The exhaust port of the dust removal filter 1 is directly discharged outside the workshop, or is connected to the ceiling of the workshop, but is not limited to this.

[0027] The utility model has the following working principle:

[0028] During dust removal, clean air is introduced into the equipment cover 2 through the filter fan 5 installed at the air inlet. The ions in the introduced air are increased by the ion generator, and the ionized air is blown to the processing station 8 in the equipment to remove the static electricity of the dust. The air blown in can then easily blow up the dust at the processing station 8. Since a plurality of return air holes are arranged below the edge of the processing station 8, a stable airflow direction can be formed with the blown in air. The blown dust is brought into the return air holes by the airflow, which can prevent the dust from flying around in the equipment cover 2 (and thus prevent the dust from falling into the corners of the equipment and being unable to be sucked away and accumulated). Then, the dust that falls into the return air holes enters the dust removal filter 1 through the dust collection duct 6 for dust removal and filtration. The dust is collected in the dust removal filter 1, and the filtered air is discharged. Through the above fluid and space ionization design, the dust-free environment inside the equipment can achieve a dynamic level of 10,000 or a static level of 1,000.
