Description

Technical Field

[0001] This utility model belongs to the field of zinc powder processing technology, and in particular relates to a cleaning mechanism for the slag discharge port of a zinc powder smelting furnace. Background Technology

[0002] Zinc powder is a fine metallic powder made of high-purity zinc and is one of the important chemical raw materials. In the process of zinc powder processing, the smelting furnace is one of the most common pieces of equipment. Zinc is heated and melted in the smelting furnace and then cooled to obtain powder. The slag discharge port is an important structural component of the smelting furnace and is used to discharge the residue inside the smelting furnace. During the long-term use of the smelting furnace, some residue will adhere to the inner wall of the slag discharge port. In order to facilitate the cleaning of the slag discharge port of the smelting furnace, a cleaning mechanism is generally used.

[0003] An existing patent announcement (CN218443344U) discloses an automatic cleaning device to prevent slag accumulation at the slag outlet of a smelting furnace. The device includes a support frame, a conveying cylinder, a motor, a screw conveyor, a guide plate, and a cleaning mechanism. This invention, by setting up a cleaning mechanism and a driving mechanism, uses a unidirectional screw to rotate a moving plate, which in turn moves a scraper to one end to the inner wall of the slag outlet. Simultaneously, the motor output drives the screw conveyor to rotate, and the driving mechanism drives a rotating ring to rotate. The rotating ring, through a connecting frame, drives the moving plate and the scraper to rotate, thus cleaning the inner wall of the slag outlet. When the cleaned slag falls into the slag outlet and accumulates, the rotating screw conveyor transports the accumulated slag to the discharge port inside the conveying cylinder. The slag is then guided into a waste collection box by the guide plate. This achieves the function of automatically cleaning the inner wall of the slag outlet, preventing slag accumulation.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The automatic cleaning device mentioned above cleans the inner wall of the slag discharge port by moving the plate and scraper. However, when in use, since the length of the scraper is fixed, it can only clean the slag discharge port at a specific depth. Since the size of the smelting furnace varies, the depth of the slag discharge port of different smelting furnaces is different, resulting in a small range of applications and low practicality.

[0006] 2. The automatic cleaning device mentioned above has its moving plate and scraper mounted on the rotating ring via a connecting frame. Since the position of the connecting frame on the rotating ring is fixed, the rotation radius of the moving plate and scraper is also fixed. However, due to the different diameters of the slag discharge ports of different smelting furnaces, it can only clean slag discharge ports of a specific diameter, resulting in a limited range of applications and low practicality.

[0007] To address these issues, we provide a cleaning mechanism for the slag discharge port of a zinc powder smelting furnace. Utility Model Content

[0008] The purpose of this utility model is to provide a cleaning mechanism for the slag discharge port of a zinc powder smelting furnace. The mechanism uses a hydraulic cylinder to drive a square rod and a cleaning disc to rise and fall, making it convenient to clean slag discharge ports of different depths through the cleaning disc. This solves the problem that existing mechanisms are not convenient for cleaning slag discharge ports of different depths. At the same time, the third sleeve and threaded rod drive the movable plate and scraper to move relative to the mounting column, adjusting the rotation diameter of the scraper, which solves the problem that existing mechanisms are not convenient for cleaning slag discharge ports of different diameters.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

A mounting frame is fixedly connected below the mounting plate. A first sleeve is rotatably connected between the mounting plate and the mounting frame. A square rod passes through the interior of the first sleeve. A hydraulic cylinder is fixedly connected to the rear end of the mounting frame, and a connecting plate is fixedly connected to the output shaft of the hydraulic cylinder. The bottom end of the square rod is rotatably connected to the front end of the upper surface of the connecting plate, and the top end of the square rod is fixedly connected to the bottom center of the cleaning disc. A cleaning component is located above the cleaning disc, including a mounting column fixedly connected to the top center of the cleaning disc. Movable plates are movably connected to both sides of the mounting column. Scrapers are fixedly connected to the outer wall of the movable plates on the side away from the mounting column.

One end of the threaded rod located on the outer side of the third sleeve is fixedly connected to the center of the outer wall of the movable plate near the mounting column.

[0011] A further feature of this invention is that: sliding grooves are provided at the front and rear ends on both sides of the lower surface of the mounting plate, and sliding rods are fixedly connected inside the sliding grooves. Sliding blocks are slidably sleeved on the outer walls of the sliding rods, and the bottoms of the sliding blocks are fixedly connected to the front and rear ends on one side of the upper surface of the mounting plate.

[0012] A further feature of this invention is that multiple positioning holes are evenly spaced at the center of both sides of the lower surface of the mounting plate, and a positioning bolt is threaded onto one side of the surface of the fixing plate, with one end of the positioning bolt threaded into the interior of one of the positioning holes.

[0013] A further feature of this invention is that fixing rods are fixedly connected to the four sides of the center of the lower surface of the mounting plate, and the bottom ends of the fixing rods are fixedly connected to the four sides of the center of the top of the mounting frame.

[0014] A further feature of this invention is that a drive motor is fixedly connected to the bottom front end of the mounting bracket, a drive gear is fixedly connected to the output shaft of the drive motor, and a driven gear is fixedly connected to the outer wall of the first sleeve, with the driven gear meshing at the rear end of the drive gear.

[0015] A further feature of this invention is that a rotating disk is fixedly connected to the bottom end of the square rod, and the rotating disk is rotatably connected inside the mounting groove located at the front end of the connecting plate surface.

[0016] A further feature of this invention is that a second sleeve is fixedly connected to the upper and lower sides of the outer walls on both sides of the mounting column, and a limiting rod is movably fitted inside the second sleeve. The end of the limiting rod located on the outer side of the second sleeve is fixedly connected to the upper and lower sides of the outer wall of the movable plate near the mounting column.

[0017] A further feature of this invention is that anti-slip sleeves are fitted on both sides of the outer wall of the third sleeve, with the anti-slip sleeves located on both sides of the mounting column.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by setting up an installation component, starts a hydraulic cylinder. The output shaft of the hydraulic cylinder drives a square rod to move through a connecting plate, which in turn drives the cleaning disc to move relative to the installation plate.

The movable plate then drives the scraper to a designated position, thereby adjusting the rotation diameter of the scraper. This facilitates cleaning of slag discharge ports of different diameters, expands the scope of application, and improves practicality. Attached Figure Description
