Description

Technical Field

[0001] The present application relates to the technical field of static elimination, and in particular to an air-supply type static elimination device. Background Art

[0002] During the production process in some cleanrooms, static eliminators are used to protect products within specific areas from static electricity. In related technologies, static eliminators primarily consist of a mounting frame and a static generating assembly connected to the frame. The static generating assembly typically consists of an ionizer and a discharge needle connected to the ionizer.

[0003] The number of electrostatic generating components is set to be multiple, and the multiple electrostatic generating components are usually arranged at intervals and connected in sequence to form a closed figure shape; the electrostatic generating components are used to release positive and negative ions during the static electricity removal process, thereby forming an area between the multiple electrostatic generating components for eliminating static electricity for the product.

[0004] Regarding the above-mentioned related technologies, there are many charged ions in the static electricity removal area between the static electricity generating components. During the process of static electricity elimination on the product, reverse charging may occur after the static electricity on the product is eliminated. Utility Model Content

[0005] In order to reduce the reverse charging of products during the static elimination process, the present application provides an air-supply type static elimination device.

[0006] The present application provides an air-supply type static elimination device that adopts the following technical solution:

[0007] An air-supply type static elimination device comprises an installation box, an electrostatic generating assembly connected to the installation box, and an air supply device arranged in the installation box, wherein the two opposite ends of the installation box are an air inlet end and an air outlet end respectively; the electrostatic generating assembly is located on one side of the air outlet end of the installation box, and the air supply device comprises an air blower and an air guide ring arranged between the air inlet hole of the air blower and the air inlet end of the installation box; the inlet of the air guide ring is larger than the air inlet end of the installation box, and the outlet of the air guide ring is adapted to the air inlet hole of the air blower.

[0008] By adopting the above technical solution, the static electricity generating assembly located on the air outlet side of the installation box is used to release ions, and the air supply device is used to supply air to the static electricity generating assembly, so that the ions generated by the static electricity generating assembly can be blown and diffused into the surrounding environment with the flowing air. This can reduce the retention of charged ions between the static electricity generating assembly, thereby reducing the reverse charging of the product during the static electricity elimination process. At the same time, the air supply device can blow the charged ions into the surrounding environment, to a certain extent increasing the range of static electricity elimination. In addition, in the air supply device, an air guide ring is used to connect the air inlet of the blower and the installation and air inlet ends, which can improve the smoothness of entry during the operation of the air supply device.

[0009] Optionally, the air inlet end of the installation box is provided with a plurality of air inlet holes, and the area where the air inlet holes are located is smaller than the inlet size of the air guide ring.

[0010] By adopting the above technical solution, the air inlet end of the installation box is set as a plurality of air inlet holes, that is, the air inlet end of the installation box is made into a sieve plate shape, which can reduce to a certain extent the situation where large-sized debris enters the interior of the installation box from the air inlet end of the installation box and hinders the operation of the blower, so that the air supply device maintains a good operating state.

[0011] Optionally, a connecting ring edge is provided at the inlet of the air guide ring, and the connecting ring edge is used to abut against the inner wall of the air inlet end of the installation box.

[0012] By adopting the above technical solution, the air outlet end of the blower is also located in the installation box, so that the air delivered by the blower will flow in the installation box. By utilizing the abutment effect between the connecting ring edge and the inner wall of the installation box, the air in the installation box can be reduced from entering the blower through the inlet of the air guide ring, which causes the air supply efficiency to decrease.

[0013] Optionally, the outlet of the air guide ring is arranged in a closed shape, and the outlet of the air guide ring can extend into the air inlet of the blower.

[0014] By adopting the above technical solution, the outlet of the air guide ring extends into the air inlet of the blower, making it convenient for the air inlet of the blower to draw air from the outer wall of the installation box through the air guide ring, thereby reducing the reduction in air supply efficiency caused by the air from the installation box entering the blower through the inlet of the air guide ring.

[0015] Optionally, a first filter is provided on the side wall where the air inlet end of the installation box is located, and the first filter can cover the air inlet end of the installation box.

[0016] By adopting the above technical solution, the first filter can further filter the air entering the air inlet end of the installation box, reducing the situation where debris enters the interior of the installation box from the air inlet end and hinders the operation of the blower, so that the air supply device maintains a good operating state.

[0017] Optionally, a second filter is provided on the side wall where the air outlet of the installation box is located, and the second filter can cover the air outlet of the installation box.

[0018] By adopting the above technical solution, the second filter can be used to filter the air out of the air outlet of the installation box, thereby improving the cleanliness of the final blown air and reducing the situation where debris adheres to products that require static electricity removal.

[0019] Optionally, the side wall where the air outlet end of the installation box is located is provided with two air outlets, the two air outlets are arranged at intervals, and the two air outlets are respectively located on both sides of the air supply fan, and the other two sides of the air supply fan are provided with air guide plates.

[0020] By adopting the above technical solution and utilizing the setting of the wind guide plate, the wind blown out by the blower is guided to the air outlet, reducing the situation where the wind force of the blower is weakened due to collision with the inner wall of the installation box, so as to maintain a good wind output rate of the blower.

[0021] Optionally, a telescopic rod is further provided between the static electricity generating assembly and the installation box.

[0022] By adopting the above technical solution, the arrangement of the telescopic rod enables the distance between the static electricity generating assembly and the installation box to be adjusted, so as to facilitate certain adjustments to the position of the static electricity elimination area.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Reduce the retention of charged ions between static-generating components, thereby reducing the reverse charge of the product during the static elimination process; at the same time, to a certain extent, increase the scope of static elimination;

[0030] The present application is further described in detail below with reference to the accompanying drawings.

[0031] The embodiment of the present application discloses an air supply type static elimination device. Figure 1 and Figure 2 An air-supply static eliminator includes an installation box 1, an electrostatic generator assembly 2 connected to the installation box 1, and an air supply device 3 installed within the installation box 1. The installation box 1 has an air inlet at its top and an air outlet at its bottom. The electrostatic generator assembly 2 is located at the bottom of the installation box 1 and is used to release charged ions. The air supply device 3 is located within the installation box 1 and is used to draw air from above the installation box 1 and send it below the installation box 1, allowing the charged ions released by the electrostatic generator assembly 2 to be blown and diffused into the surrounding environment by the flowing air.

[0032] In this embodiment, the installation box 1 is rectangular and is composed of multiple rectangular panels. A telescopic rod 4 is connected between the static electricity generating assembly 2 and the installation box 1. This allows for connection between the static electricity generating assembly 2 and the installation box 1, and the distance between the static electricity generating assembly 2 and the installation box 1 can be adjusted. In this embodiment, the telescopic rod 4 is composed of at least two mating sleeves.

[0033] Specifically, the static electricity generating assembly 2 includes an ion generator 21 and a discharge needle 22 connected to the ion generator 21. The ion generator 21 is fixedly connected to the lower end of the telescopic rod 4, specifically by bolts, to allow for detachable connection between the ion generator 21 and the telescopic rod 4. The discharge needle 22 is electrically connected to the ion generator 21 to release charged ions.

[0034] The air supply device 3 is used to supply air from top to bottom. Specifically, the air supply device 3 includes an air supply fan 31 and an air guide ring 32. The air supply fan 31 is installed on the inner bottom wall of the installation box 1. In the present embodiment, the air supply fan 31 is an electrically driven centrifugal fan, that is, the air supply fan 31 takes in air axially and discharges air radially.

[0035] The air inlet 11 of the blower 31 is aligned with the air inlet end of the mounting box 1, and the air guide ring 32 is located between the air inlet 11 of the blower 31 and the air inlet end of the mounting box 1. The air guide ring 32 is hollow, and one end of the air guide ring 32 relative to the air inlet end of the mounting box 1 is open as an inlet. A connecting ring rim 321 is formed at the inlet of the air guide ring 32. The connecting ring rim 321 is connected to the inner top wall of the mounting box 1 via bolts to achieve relative fixation between the air guide ring 32 and the mounting box 1. Correspondingly, one end of the air guide ring 32 relative to the air inlet 11 of the blower 31 is open as an outlet. The outlet of the air guide ring 32 is configured in a closed shape, and the outlet of the air guide ring 32 can extend into the air inlet 11 of the blower 31.

[0036] At the same time, when the air guide ring 32 is connected to the installation box 1, the inlet of the air guide ring 32 can surround the air inlet end of the installation box 1. In this embodiment, the air inlet end of the installation box 1 is composed of a plurality of small air inlet holes 11 formed in the upper end surface. In addition, a first filter 5 is mounted on the upper surface of the installation box 1 via bolts. The first filter 5 can block and cover all the air inlet holes 11 on the upper end surface of the installation box 1, thereby blocking and filtering debris in the incoming air flow.

[0037] Reference Figure 2 and Figure 3 The lower end surface of the mounting box 1 is provided with two air outlets 12, forming the air outlet of the mounting box 1. Specifically, the two air outlets 12 are spaced apart and located on either side of the blower 31. Accordingly, the other two sides of the blower 31 are provided with air guide plates 13, which are bolted to the mounting box 1. When the blower 31 is in operation, air is blown out from the sides of the blower 31. The air guide plates 13 ensure that the air supplied by the blower 31 is collected at the air outlets 12 of the mounting box 1 and blown toward the static electricity generating assembly 2.

[0038] In addition, a second filter 6 is installed on the lower surface of the installation box 1. The second filter 6 can block the two air outlets 12 so that the second filter 6 can further filter the airflow sent out from the two air outlets 12, effectively improving the cleanliness of the final blown air.

[0039] The implementation principle of the air-supply type static elimination device of the embodiment of the present application is as follows: the static electricity generating component 2 located on the air outlet side of the installation box 1 is used to release ions, and the air supply device 3 is used to supply air to the static electricity generating component 2, so that the ions generated by the static electricity generating component 2 can be blown and diffused to the surrounding environment along with the flowing air, which can reduce the retention of charged ions between the static electricity generating components 2, thereby reducing the reverse charging of the product during the static electricity elimination process. At the same time, the air supply of the air supply device 3 can blow the charged ions into the surrounding environment, to a certain extent, increase the scope of static electricity removal; and in the air supply device 3, the air guide ring 32 is used to connect the air inlet 11 of the blower 31 and the installation and air inlet end, which can improve the smoothness of entry during the operation of the air supply device 3.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
