[0032] In order to have a clearer understanding of the technical solution, purpose and effect of the present invention, the specific implementation of the present invention is now described in conjunction with the accompanying drawings. Among them, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more.

[0033] like Figure 1 As shown, the present invention provides an electrostatic conveyor belt 10, which includes an insulating base layer 1 and an insulating adsorption layer 2, wherein:

[0034] The insulating base layer 1 has a first surface and a second surface arranged opposite to each other, and a plurality of alternately arranged positive electrode plates 11 and negative electrode plates 12 are embedded on the first surface, that is, adjacent positive electrode plates 11 and negative electrode plates 12 are separated by the insulating base to avoid breakdown, preferably, each adjacent positive electrode plate 11 and negative electrode plate 12 is arranged at equal intervals, that is, the positive electrode plates 11 and negative electrode plates 12 are alternately arranged and evenly distributed on the first surface, so that the generated charge is evenly distributed, and;

[0035] The insulating adsorption layer 2 has a connecting surface and an adsorption surface 21 which are relatively arranged, and the connecting surface is attached to the first surface. Specifically, the insulating adsorption layer 2 is connected to the insulating base layer 1 by an injection molding and extrusion process, and the connecting surface can be in contact with the adsorbed object 20. The connecting surface and the adsorption surface 21 are uneven, that is, the connecting surface has a certain surface roughness, so that the insulating adsorption layer 2 can form an air gap with the adsorbed object 20 to facilitate the adsorption of debris. In addition, the setting of the insulating adsorption layer 2 can prevent leakage to ensure safety during use.

[0036] When using, Figure 2 As shown, the positive electrode plate 11 and the negative electrode plate 12 are connected to the positive and negative electrodes of a high-voltage power supply respectively, and charges of equal magnitude and opposite polarities are accumulated, so that the adsorption surface 21 is in contact with the adsorbed object 20 to polarize the surface of the adsorbed object 20, thereby accumulating bound charges of opposite polarities on the surface of the adsorbed object 20, and the free charges on the electrostatic conveyor belt 10 and the bound charges of opposite polarities on the surface of the adsorbed object 20 are adsorbed through the action of the electric field, that is, the electrostatic conveyor belt 10 adsorbs the debris on the surface of the adsorbed object 20 through electrostatic adsorption.

[0037] Among them, the electrostatic conveyor belt 10 and the surface of the adsorbed object 20 actually constitute a capacitor system, which can be called an adsorption capacitor Cx. In the adsorption capacitor, the adjacent positive electrode plate 11 and the negative electrode plate 12 serve as the two electrodes of the capacitor, and the dielectric layer between the two electrodes is composed of the adsorption surface 21, the air layer, the surface of the adsorbed object 20 and the insulating base layer 1 between the two electrode plates (the adjacent positive electrode plate 11 and the negative electrode plate 12).

[0038] The electrostatic conveyor belt 10 of the present invention utilizes the principle of electrostatic adsorption to remove debris on the surface of the adsorbed object 20, thereby having the advantages of light weight, low power consumption, low noise, and strong adaptability to wall surfaces.

[0039] Furthermore, the second surface is covered with a fabric layer 3, which can increase the strength and wear resistance of the insulating base layer 1. Preferably, metal wires can be mixed into the fabric layer 3 to ensure that there is no accumulation of static electricity inside the electrostatic conveyor belt 10.

[0040] Furthermore, the thickness of the fabric layer 3 is 0.4 mm to 0.6 mm, and preferably, the thickness of the fabric layer 3 is 0.5 mm, so that the fabric layer 3 can protect the insulating base layer 1 without affecting the overall quality of the electrostatic conveyor belt 10 .

[0041] Furthermore, the insulating base layer 1 and the insulating adsorption layer 2 are both polyurethane layers (PU layers), that is, the insulating base layer 1 and the insulating adsorption layer 2 are both made of polyurethane material by injection molding and extrusion. The polyurethane layer has the advantages of oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness and elasticity, thereby ensuring the service life of the electrostatic conveyor belt 10.

[0042] Furthermore, the thickness of the insulating adsorption layer 2 is 0.1 mm to 0.2 mm. Such a thickness can not only play a good role in preventing leakage, but also adsorb the debris on the surface of the adsorbed object 20 through electrostatic adsorption.

[0043] Furthermore, the thickness of the insulating base layer 1 is 0.6 mm to 0.8 mm. Preferably, the thickness of the insulating base layer 1 is 0.7 mm, so as to facilitate the connection between the positive electrode plate 11 and the negative electrode plate 12 .

[0044] Furthermore, the positive electrode plate 11 and the negative electrode plate 12 are both electrostatic ink blocks. Specifically, the positive electrode plate 11 and the negative electrode plate 12 are both coated on the first surface with electrostatic ink, and PU is filled between adjacent positive electrode plates 11 and negative electrode plates 12 to ensure that adjacent positive electrode plates 11 and negative electrode plates 12 are separated by insulating materials.

[0045] Furthermore, the thickness of the electrostatic ink block is 0.5 mm to 1.5 mm. Preferably, the thickness of the electrostatic ink block is 0.1 mm. The specific size of the electrostatic ink block can be adjusted as needed.

[0046] It should be noted that there needs to be sufficient vacuum between the adjacent positive electrode plates 11 and negative electrode plates 12 to avoid sparking and breakdown.

[0047] Furthermore, the adsorption surface 21 is covered with a surface treatment agent layer. Specifically, the adsorption surface 21 is treated with a surface treatment agent to form the surface treatment agent layer to prevent electrostatic failure in a high humidity environment.

[0048] like Figure 3 As shown, the present invention further provides a de-dusting machine 100 , which includes the above-mentioned electrostatic conveyor belt 10 . Therefore, the de-dusting machine 100 has all the advantages of the above-mentioned electrostatic conveyor belt 10 .

[0049] It should be noted that the specific structure and working principle of the impurity remover 100 are prior art and will not be described in detail here.

[0050] In summary, the electrostatic conveyor belt of the present invention utilizes the principle of electrostatic adsorption to remove debris on the surface of the adsorbed object, thereby having the advantages of light weight, low power consumption, low noise and strong adaptability to the wall surface.

[0051] The impurity remover of the present invention has the above-mentioned electrostatic conveyor belt, and therefore, the impurity remover has all the advantages of the above-mentioned electrostatic conveyor belt.

[0052] The above description is only an illustrative specific implementation mode of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the present invention should fall within the scope of protection of the present invention. It should also be noted that the various components of the present invention are not limited to the above-mentioned overall application. The various technical features described in the specification of the present invention can be selected one by one or multiple ones can be selected and used in combination according to actual needs. Therefore, the present invention naturally covers other combinations and specific applications related to the invention point of this case.
