Description

Technical Field

[0001] This utility model relates to the field of electrical control technology, specifically to an electrical control device for a sintering machine ash discharge valve. Background Technology

[0002] Sintering machine ash discharge valves are a common type of equipment in industrial production, mainly used to control the discharge of powdery or granular materials. A sintering machine ash discharge valve typically refers to a valve installed at the bottom of equipment storing or conveying powdery or granular materials (such as silos, bins, belt conveyors, etc.) to control material discharge. This valve can be operated manually or automatically to ensure that materials are discharged evenly, continuously, or quantitatively. Sintering machine ash discharge valves are widely used in building materials, chemical, power, grain processing, mining, and other industries, especially when handling powdery or granular materials such as coal, limestone, cement, and grains.

[0003] A search revealed a utility model patent with publication number CN217363611U, which discloses an electrical control system for a sintering machine ash discharge valve, belonging to the field of electrical control systems. This electrical control system includes an electrical control body and a lifting mechanism. The electrical control body includes an electrical control box with a hinged door at the front end and a conical canopy on top. The lifting mechanism includes a base and a lifting plate. The base has an internal mounting groove containing a motor. Screws are rotatably mounted on both sides of the top of the base, and the motor is connected to the screws on both sides. The lifting plate has threaded connections at both ends to the screws on both sides. The electrical control box is mounted on top of the lifting plate, facilitating the lifting of the control box.

[0004] However, the above design still has shortcomings. In the above design, the electrical control system of the sintering machine ash discharge valve is easy to lift and lower the control box, but the dust removal effect is insufficient. Since it is the control box of the ash discharge device, the working environment will inevitably generate a lot of dust. The dust inside the device will cover the electrical components, resulting in poor heat dissipation, causing the components to overheat and malfunction. In addition, the accumulation of dust may cause poor electrical contact, leading to circuit interruption or misoperation. Therefore, we propose an electrical control device for the sintering machine ash discharge valve to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical control device for the ash discharge valve of a sintering machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrical control device for a sintering machine ash discharge valve, comprising a device body, two dustproof and breathable meshes connected to the inner wall of the device body, a support plate connected to the right side of the device body, a dust collection box provided on the upper surface of the support plate, a baffle hinged to the front of the dust collection box, a fan connected to the back of the dust collection box, the output end of the fan penetrating through the outer wall of the dust collection box and communicating with the interior, a motor connected to the back of the fan, a rotating shaft connected to the inner wall of the fan, the output end of the motor penetrating through the outer wall of the fan and fixedly connected to the rotating shaft, and suction pipes connected to the upper surface and right side of the dust collection box, with the end of each suction pipe away from the dust collection box penetrating through the outer wall of the device body and communicating with the interior.

[0007] The device body has a cabinet door hinged to its front, a set of support legs installed on its bottom, and a visualization glass attached to the inner wall of the cabinet door.

[0008] The cabinet door has a display unit installed on its front side, and the display unit has adjustment buttons installed on its front side.

[0009] The cabinet door is equipped with a warning light and a buzzer.

[0010] The device body has a motor mounted on its back side, a rotating shaft connected to the inner wall of the device body, an output end of the motor penetrating the outer wall of the device body and fixedly connected to one end of the rotating shaft, a cooling fan mounted on the outer surface of the rotating shaft, and a protective cover connected to the inner wall of the device body.

[0011] The device body has heat dissipation grooves on both the left and right sides, and a converter is connected to the inner bottom wall of the device body.

[0012] The device body has a main switch installed on its inner top wall, a programmable logic controller connected to its inner wall, and a microprocessor on its upper surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention effectively isolates external dust by setting up a dustproof and breathable mesh and heat dissipation slots, reducing the chance of dust entering the internal system. The negative pressure generated by the motor-driven fan draws internal dust through the suction pipe to the dust collection box, achieving automatic cleaning of the equipment. The combination of the dustproof and breathable mesh and the dust collection system makes equipment maintenance more convenient and reduces the risk of damage to the device due to dust.
