Description

Technical Field

[0001] This utility model relates to the field of material silo anti-blocking technology, specifically a raw material silo discharge anti-blocking and flow-aiding system. Background Technology

[0002] The lower silos of raw material batching plants are generally conical in shape. When materials flow to the silo outlet, the small diameter and low throughput of the outlet make it easy for materials to agglomerate and clog. Furthermore, changes in material composition—such as smaller particle size, a higher proportion of small particles, increased viscosity, or higher moisture content—can also lead to material adhesion and outlet blockage. Blockage necessitates manual cleaning and shoveling, increasing labor intensity, impacting production efficiency, and posing safety hazards for cleaning workers. Therefore, it is urgent to address the silo blockage problem and improve the silo's adaptability to different materials. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a raw material silo discharge anti-blockage and flow-aiding system that can avoid manual cleaning and ensure smooth material discharge from the silo.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A raw material silo discharge anti-clogging and flow-aiding system includes a transition silo connected below the raw material silo. The upper opening of the transition silo is adapted to the lower opening of the raw material silo, and the lower opening of the transition silo is circular. A discharge hopper is connected below the transition silo, and a rotary unclogging mechanism is connected below the discharge hopper. The rotary unclogging mechanism includes a rotating drum, which is rotatably connected to the lower end of the discharge hopper via a slewing bearing. The rotating drum is equipped with a scraper for cleaning the inner wall of the discharge hopper and an agitator for loosening the material in the discharge hopper. The scraper and agitator extend from the rotating drum toward the discharge hopper, and the agitator is inclined from bottom to top toward the axis of the discharge hopper. A connecting seat is provided on the rotating drum, and the lower ends of the scraper and agitator are hinged to the connecting seat and locked and fixed by a locking screw and a locking nut. The system also includes a drive mechanism for driving the rotating drum to rotate, including a drive motor. The output shaft of the drive motor is connected to a drive gear. The rotating drum is connected to the outer ring of the slewing bearing, and the discharge hopper is connected to the inner ring of the slewing bearing. The outer ring of the slewing bearing has external teeth, and the drive gear meshes with the external teeth of the slewing bearing.

[0006] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:

[0007] The scraper can clean the material adhering to the inner wall of the discharge hopper, and the stirring rod can unclog the material in the discharge hopper, preventing the material from agglomerating and ensuring that the material in the entire discharge hopper is in a flowing state, fundamentally solving the problem of material blockage in the hopper; at the same time, the rotating anti-blockage mechanism is located at the bottom, which is convenient for installation, disassembly and later maintenance. The scraper and stirring rod can be directly removed from the bottom for regular cleaning or replacement.

[0008] As a preferred embodiment, a further technical solution of this utility model is:

[0009] Preferably, the connecting seat includes a first connecting ear and a second connecting ear. The first connecting ear is fixedly connected to the inner side wall of the rotating drum, and the second connecting ear is slidably connected to the inner side wall of the rotating drum. The scraper and the stirring rod are both provided with connecting sleeves at their lower ends. The connecting sleeves are located between the first connecting ear and the second connecting ear. The locking screw passes through the first connecting ear, the connecting sleeve and the second connecting ear, and is locked and fixed by the locking nut.

[0010] Preferably, a T-shaped slide rail is provided on the inner side wall of the rotating drum, and limit baffles are provided at both ends of the T-shaped slide rail; the second connecting ear is provided with a slide groove that matches the T-shaped slide rail, and the second connecting ear is slidably connected to the T-shaped slide rail through the slide groove.

[0011] Preferably, the connecting sleeve is provided with a number of first limiting teeth at intervals on both sides in a circumferential manner, and the corresponding first connecting ear and second connecting ear are provided with a number of second limiting teeth on their sides; this prevents the connecting sleeve from sliding between the connecting seat after the locking nut is tightened, and ensures the cleaning effect of the scraper on the inner wall of the discharge bin.

[0012] Preferably, a number of first air cannons are arranged circumferentially on the raw material silo, and a number of second air cannons are arranged circumferentially on the transition silo; to ensure that the material flows smoothly from the raw material silo to the transition silo, and from the transition silo to the discharge silo.

[0013] Preferably, a bar valve is installed between the raw material silo and the transition silo; if the rotary unblocking mechanism malfunctions during production, the bar valve can be closed and the material below the bar valve can be emptied for emergency repair.

[0014] Preferably, when the bottom opening of the raw material silo is rectangular, the four side edges of the transition silo are rounded to avoid material jamming at the side edges of the transition silo. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0021] like Figure 1 As shown, this embodiment provides a raw material silo discharge anti-clogging and flow-aiding system, including a transition chamber 2 connected below the raw material silo 1. The upper opening shape of the transition chamber 2 is adapted to the lower opening shape of the raw material silo 1, and the lower opening shape of the transition chamber 2 is circular. A discharge hopper 3 is connected below the transition chamber 2, and a rotary unclogging mechanism is connected below the discharge hopper 3. Figure 2 The rotary unblocking mechanism includes a rotating drum 4, which is rotatably connected to the lower end of the discharge hopper 3 via a slewing bearing 5. Inside the rotating drum 4 are scrapers 10 for cleaning the inner wall of the discharge hopper 3 and stirring rods 11 for loosening the material inside the discharge hopper 3. The scrapers 10 and stirring rods 11 extend from the rotating drum 4 towards the discharge hopper 3, with the stirring rods 11 inclined upwards towards the axis of the discharge hopper 3. A connecting seat 12 is provided on the rotating drum 4, and the lower ends of the scrapers 10 and stirring rods 11 are hinged to the connecting seat 12 and locked in place by locking screws and locking nuts. It also includes a drive mechanism 6 for rotating the rotating drum 4, including a drive motor 601, the output shaft of which is connected to a drive gear 602. The rotating drum 4 is connected to the outer ring 502 of the slewing bearing 5, and the discharge hopper 3 is connected to the inner ring 501 of the slewing bearing 5. External teeth 503 are provided on the outer side of the outer ring 502 of the slewing bearing 5, and the drive gear 602 meshes with the external teeth 503 of the slewing bearing 5. In this embodiment, the lower opening of the raw material silo 1 is rectangular. To avoid material jamming at the side edges of the transition silo 2, the four side edges of the transition silo 2 are designed with rounded corners.

[0022] The drive motor 601 drives the drive gear 602 to rotate, which in turn drives the rotating drum 4 to rotate. When the rotating drum 4 rotates, the scraper 10 and the stirring rod 11 rotate synchronously. The scraper 10 can clean the material attached to the inner wall of the discharge hopper 3, and the stirring rod 11 can agitate the material in the discharge hopper 3, increase the fluidity of the material in the discharge hopper 3, prevent the material from sticking to the side wall, and ensure the material passing capacity at the bottom of the discharge hopper 3, thus fundamentally solving the problem of material blockage in the hopper. At the same time, after long-term use, the scraper 10 and the stirring rod 11 are prone to material sticking, thereby reducing the cleaning effect on the inner wall of the discharge hopper 3 and increasing the resistance when agitating the material. With this structure, the scraper 10 and the stirring rod 11 can be directly removed from the bottom for cleaning or replacement, which is convenient for regular cleaning or replacement. The installation angle of the scraper 10 and the stirring rod 11 can be adjusted according to the actual working conditions (such as the particle size of the material and the moisture content of the material) and the length of the scraper 10 and the stirring rod 11 themselves.

[0023] like Figure 2 The connecting seat 12 includes a first connecting ear 1201 and a second connecting ear 1202. The first connecting ear 1201 is fixedly connected to the inner wall of the rotating drum 4, and the second connecting ear 1202 is slidably connected to the inner wall of the rotating drum 4. The lower ends of the scraper 10 and the stirring rod 11 are provided with connecting sleeves 13, which are located between the first connecting ear 1201 and the second connecting ear 1202. The locking screw passes through the first connecting ear 1201, the connecting sleeve 13 and the second connecting ear 1202, and is locked and fixed by the locking nut. The installation angle of the scraper 10 and the stirring rod 11 can be adjusted by loosening the locking nut. After removing the locking nut and the locking screw, the scraper 10 and the stirring rod 11 can be removed. The structure is simple and easy to install and maintain.

[0024] like Figure 4 The inner wall of the rotating drum 4 is provided with a T-shaped slide rail 16, and the two ends of the T-shaped slide rail 16 are provided with limit baffles; the second connecting ear 1202 is provided with a slide groove that is adapted to the T-shaped slide rail 16, and the second connecting ear 1202 is slidably connected to the T-shaped slide rail 16 through the slide groove.

[0025] like Figure 3 , Figure 4 To prevent the connecting sleeve 13 from sliding between the connecting seat 12 after the locking nut is tightened, a number of first limiting teeth 14 are provided circumferentially on both sides of the connecting sleeve 13, and a number of second limiting teeth 15 are provided on the sides of the corresponding first connecting ear 1201 and second connecting ear 1202.

[0026] like Figure 1The raw material silo 1 is provided with several first air cannons 7 arranged in a circumferential pattern, and the transition silo 2 is provided with several second air cannons 8 arranged in a circumferential pattern. The drive motor 601, the first air cannons 7, and the second air cannons 8 are all mounted on the raw material silo 1, the transition silo 2, or the discharge hopper 3 by mounting brackets. The first air cannons 7 and the second air cannons 8 can further enhance the flow-aiding performance of this system and ensure that the material flows smoothly from the raw material silo 1 to the transition silo 2 and from the transition silo 2 to the discharge silo.

[0027] like Figure 1 In this embodiment, a bar valve 9 is installed between the raw material silo 1 and the transition silo 2. In the event of an emergency failure of the rotary unblocking mechanism during production, the bar valve 9 is immediately closed, and the material under the bar valve 9 is emptied before emergency repairs can be carried out on the rotary unblocking mechanism.

[0028] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
