Description

Technical Field

[0001] This utility model relates to the technical field of mineral admixture conveying equipment, and in particular to a dredging device for a mineral admixture discharge pipe. Background Technology

[0002] In many fields, such as building materials production, mineral admixtures, such as fly ash and slag powder, are frequently used. These mineral admixtures are usually transported via feed pipes to subsequent processing stages. However, due to their inherent properties, mineral admixtures are prone to moisture absorption and clumping, or they may adhere to the feed pipe walls during transport due to electrostatic adsorption, causing blockages over time and severely impacting production continuity and efficiency. Traditional unblocking methods often involve manually tapping the feed pipe, which is not only labor-intensive and inefficient but also prone to damaging the pipe. Some methods use simple air blowing devices, but these are ineffective at clearing stubborn blockages and fail to meet actual production needs. Therefore, this paper presents a device for unblocking mineral admixture feed pipes. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a dredging device for mineral admixture feeding pipes. Through the combined use of an air blowing mechanism, an elastic support mechanism, and a lifting component, high-pressure gas is used to impact the material and move the blocked material along the axial direction of the feeding pipe body. At the same time, vibration is used to assist in dredging, effectively clearing clumps of material. Compared with manual knocking and simple air blowing, the efficiency is greatly improved, overcoming the shortcomings of existing technologies.

[0005] A device for unblocking a mineral admixture feeding pipe includes a feeding pipe body, a support pipe provided on the outside of the feeding pipe body, an air blowing mechanism provided on the support pipe, three strip-shaped holes equally spaced along the axial direction on the side wall of the feeding pipe body, a slider slidably engaged at each of the three strip-shaped holes, a toggle plate connected to one end of each slider facing the inner wall of the feeding pipe body, and an elastic support mechanism connected to the portion of the three sliders located outside the feeding pipe body, the elastic support mechanism being connected to a lifting component.

[0006] As a further embodiment of this utility model: the air blowing mechanism includes three air blowing pipes fixed at equal intervals on the support pipe. The lower ends of the three air blowing pipes are connected to the interior of the main body of the feeding pipe. The upper ends of the three air blowing pipes extend obliquely to the outside of the support pipe and are connected to an annular air pipe. An air delivery pipe is connected to the annular air pipe, and one end of the air delivery pipe is connected to an air compressor.

[0007] As a further improvement of this utility model: the actuating plate is closely attached to the inner wall of the feed tube body, and the actuating plate is provided with actuating teeth.

[0008] As a further embodiment of this utility model: the elastic support mechanism includes a movable rod that is movably inserted into the slider, the lower end of the movable rod is connected to a support block, and a spring is sleeved on the part of the movable rod located between the slider and the support block.

[0010] As a further improvement of this utility model, an electromagnetic vibrator is installed at the upper end of each of the three sliders.

[0011] The beneficial effects of this utility model are as follows:

[0012] By using a combination of air blowing mechanism, elastic support mechanism and lifting component, high-pressure gas is used to impact the material and move the blocked material along the axis of the main body of the feed pipe.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1, referring to Figs. 1-3A device for unblocking a mineral admixture feeding pipe includes a feeding pipe body 1, a support pipe 4 provided on the outside of the feeding pipe body 1, an air blowing mechanism provided on the support pipe 4, three strip holes 6 are equally spaced along the axial direction on the side wall of the feeding pipe body 1, and sliders 14 are slidably engaged at each of the three strip holes 6. A toggle plate 7 is connected to one end of each slider 14 facing the inner wall of the feeding pipe body 1, and an elastic support mechanism is connected to the part of each slider 14 located outside the feeding pipe body 1. The elastic support mechanism is connected to a lifting component, and an electromagnetic vibrator 8 is installed at the upper end of each of the three sliders 14.

[0019] The air blowing mechanism includes three air blowing pipes 13 fixed at equal intervals on the support pipe 4. The lower ends of the three air blowing pipes 13 are connected to the interior of the feed pipe body 1. The upper ends of the three air blowing pipes 13 extend obliquely to the outside of the support pipe 4 and are connected to an annular air pipe 10. An air delivery pipe 9 is connected to the annular air pipe 10, and one end of the air delivery pipe 9 is connected to an air compressor.

[0020] The agitator plate 7 is in close contact with the inner wall of the feed pipe body 1, and the agitator plate 7 is provided with agitator teeth, which facilitate the crushing of materials when the agitator plate 7 moves.

[0021] The elastic support mechanism includes a movable rod 5 that is movably inserted into the slider 14. The lower end of the movable rod 5 is connected to a support block 12. A spring 11 is fitted on the part of the movable rod 5 located between the slider 14 and the support block 12.

[0022] The lifting assembly includes a hydraulic push rod 3 connected to the lower end of the support block 12, and a fixing block 2 is provided on the outside of the feed pipe body 1. The lower end of the hydraulic push rod 3 is connected to the fixing block 2.

[0023] Working principle: This device can be installed at the part of the feed pipe body 1 that is prone to blockage. When blockage occurs, by opening the valve of the air compressor, high-pressure air is blown into the feed pipe body 1 through the air blowing pipe 13. The air blowing pipe 13 can be set at a certain angle with the feed pipe body 1, which can generate a stronger impact force on the material clumps on the inner wall of the feed pipe body 1, greatly improving the gas unblocking effect. At the same time, the hydraulic push rod 3 pushes the support block 12 and the movable rod 5 to move upward. Through the elastic support of the spring 11, the slider 14 is pushed along the strip hole 6 to drive the actuating plate 7 to move upward, thereby moving the material. Then the hydraulic push rod 3 retracts and resets, and the electromagnetic vibrator 8 is turned on to drive the slider 14 and the actuating plate 7 to vibrate, causing the stuck material to vibrate, thereby enhancing the unblocking effect.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
