Description

Technical Field

[0001] This utility model relates to the technical field of static electricity elimination equipment, specifically to a static electricity elimination device for use on horizontal descaling equipment. Background Technology

[0002] During pneumatic conveying, plastic granules typically require a horizontal de-dust collector to separate and remove dust adhering to them. The horizontal de-dust collector is equipped with an electrostatic eliminator at the feed inlet. A high-voltage current discharges positive and negative ions from the metal tips inside the eliminator. Simultaneously, an air-filled tube blows these ions through the eliminator, creating an ionized airflow that eliminates static electricity on the surface of the plastic granules, thus improving the quality of de-dust removal.

[0003] Currently, static eliminators are usually fixed on a bracket, with a pneumatic hose and a high-voltage power line connected to their tail. Ions are blown through the pneumatic hose. The static eliminator used on the current powder remover uses a bracket and an air-filled tube as separate units. Since the pneumatic hose on each static eliminator needs to be connected to the air-filled tube, the pneumatic hose occupies a lot of equipment space. At the same time, the high-voltage cable is exposed during the process of connecting the static eliminator to the junction box, which is prone to damage and breakage, posing a safety hazard. Utility Model Content

[0004] The purpose of this invention is to address the problems of existing static eliminators used in powder removers, such as large space occupation, exposed cables, low protection, easy damage and breakage, and significant safety hazards. This invention provides a static eliminator for horizontal powder removers, thus solving the aforementioned problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0008] Several static elimination units, which are used to generate positive and negative ions, are respectively arranged in the mounting holes and located in the internal cavity of the bracket body;

[0009] An air blowing unit, which is connected to the connecting flange, is used to blow compressed air into the static elimination unit to form an ion wind. The air blowing unit is also provided with a lead wire connector that communicates with the cavity. The lead wire connector is used to lead the high voltage wires of each static elimination unit from the cavity to the outside.

[0010] And a junction box, which is located outside the bracket body, is used to connect to the high-voltage line, and the high-voltage line is used to pass high voltage to cause the static eliminator to discharge and generate positive and negative ions.

[0011] Furthermore, an electrostatic elimination device for a horizontal powder removal equipment includes a flexible tube, the two ends of which are connected to the lead connector and the junction box, respectively; the high-voltage wires of several electrostatic elimination units are bundled sequentially in the cavity and then pass through the lead connector into the flexible tube, and then connected to the junction box.

[0012] Furthermore, an electrostatic elimination device for a horizontal descaling device: the inclined plate and the support body have an included angle α satisfying 30°≤α≤60°.

[0013] Preferably, the included angle α is set to 45°, which can more easily guide the material falling from the discharge port of the horizontal de-powdering equipment, and at the same time facilitates the material to fully contact the ion wind.

[0014] Furthermore, an electrostatic eliminator for a horizontal descaling device: the air blowing unit includes the following structural configuration:

[0015] The mounting plate has several through-holes and the lead wire connectors. The mounting plate is fixedly connected to the connecting flange by bolts.

[0016] An air bag is disposed on the mounting plate along its length, and its interior is connected to the air outlet. One end of the air bag is open and the other end is closed.

[0017] An air bag tube, which is connected to one end of the air bag (i.e., connected to the open end of the air bag), is used to introduce compressed air into its interior.

[0018] And an air inlet flange, which is connected to the end of the air jacket pipe, and has an air inlet that communicates with the end of the air jacket pipe. The air inlet flange is used to connect and fix to an external compressed air supply device. Compressed air is stored in the air jacket through the air inlet flange and the air jacket pipe, and then the compressed air is blown to the static eliminator by a pneumatic hose.

[0019] Specifically, the air outlet is configured as a through tapered threaded hole.

[0020] Furthermore, an electrostatic eliminator for use on a horizontal descaling device includes a sealing gasket between the mounting plate and the connecting flange.

[0021] Furthermore, an electrostatic elimination device for a horizontal descaling device is provided: a quick-release coupling extending into the cavity is also provided on the air outlet.

[0022] Specifically, the number of quick-release ferrule connectors is the same as the number of static eliminators.

[0023] Furthermore, an electrostatic eliminator for a horizontal powder removal device includes: an electrostatic eliminator, a pneumatic hose, and an annular sealing ring; the electrostatic eliminator is disposed in the mounting hole, the two ends of the pneumatic hose are respectively connected to the electrostatic eliminator and a quick-release coupling, a sealing groove is provided around the circumference of the electrostatic eliminator, and the annular sealing ring is disposed in the sealing groove to seal the gap between the electrostatic eliminator and the mounting hole.

[0024] Specifically, the main body of the static eliminator can be configured as a cylindrical structure, and its end can be configured as an inclined surface with the same inclination angle as the inclined plate.

[0025] Furthermore, an electrostatic elimination device for a horizontal descaling device: the pneumatic hose is coiled in the cavity, with its longitudinal direction being annular and its transverse direction being point-to-point grouped cross connections.

[0026] Furthermore, an electrostatic eliminator for use on a horizontal descaling device includes a set screw in the inclined plate for fixing the electrostatic eliminator in the mounting hole.

[0027] Furthermore, an electrostatic eliminator for use on a horizontal de-powdering equipment: a rectangular sealing groove is provided around the inclined plate, and a sealing strip is provided in the sealing groove to ensure the sealing between the electrostatic eliminator and the horizontal de-powdering equipment.

[0028] The beneficial effects of this utility model are:

[0029] This utility model designs an electrostatic eliminator for horizontal powder removal equipment. Its compact structure reduces the space required on the equipment while enhancing the protection of high-voltage lines and pneumatic hoses, thus improving equipment safety. Specifically, the pneumatic hoses are arranged in a longitudinal annular coil and laterally grouped cross-connected configuration within the cavity. This improves the operability of assembling the mounting plate (air blowing unit) and connecting flange (support unit), facilitating assembly and increasing the curvature of the pneumatic hose after bending, preventing excessive bending. Furthermore, it reduces the volume of the support body, minimizing space occupation. Additionally, this utility model incorporates an explosion-proof flexible conduit, connecting the lead wire connector and junction box. The high-voltage lines are run through the explosion-proof flexible conduit, enhancing cable protection, preventing damage and breakage, and further improving equipment safety.

[0030] This utility model designs an electrostatic eliminator for horizontal de-powdering equipment. By merging the support unit and the air blowing unit, the overall structure becomes more compact. This not only protects the pneumatic hose but also reduces the installation space. Furthermore, the pneumatic hose on the electrostatic eliminator can be connected to the air manifold via a quick-release coupling, making installation more convenient. Moreover, the pneumatic hose is located in the internal cavity of the support body, which can prevent aging and damage. Attached Figure Description
