Abstract
Description
Technical Field
[0001] This utility model relates to the field of silo equipment technology, and in particular to a stable feeding device for silos. Background Technology
[0002] Currently, in bulk material handling systems in my country, especially for silos storing loose materials with poor viscosity and flowability (water-absorbing, caking materials), arching is the most common fault. When storing loose materials with poor viscosity and flowability in silos, conventional methods for breaking arches are limited. In the lower silo, material flow is often obstructed. While air cannons are typically used in the upper silo for breaking up and cleaning the caking material, this is insufficient and cannot fully remove the caking material. This makes it difficult to remove silo blockages, adhesion to the walls, and stagnation, rendering the silo unusable. This leads to continuous feeding at the inlet, causing silo overflow, and simultaneously, material blockage at the outlet. Furthermore, because the silo is not transparent, this situation cannot be detected in time. To solve these technical problems, this utility model provides a stable feeding device for silos. Utility Model Content
[0003] This utility model provides a stable feeding device for a silo, which can prevent material from arching and blocking at the silo outlet, and has a smooth material discharge function. At the same time, it controls the feeding and discharging by monitoring the material level in real time through a material level sensor, thus solving the problem of silo overflow and blockage.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A stable feeding device for a silo includes a silo, a feeding quantitative conveying mechanism, a discharging quantitative conveying mechanism, a material level detection mechanism, and a scraping and arch-breaking mechanism. The silo has a feed inlet at its top, one end of which is connected to the outlet end of the feeding conveying mechanism. The silo has a discharge outlet at its bottom. The material level detection mechanism includes two material level sensors installed vertically and horizontally on the silo. The scraping and arch-breaking mechanism is installed at the discharge outlet, with its top connected to the outlet and its bottom connected to the inlet end of the discharging quantitative conveying mechanism. The scraping and arch-breaking mechanism has a discharge channel, and a scraper plate rotating along the discharge outlet and the lower inner wall of the silo is installed within the discharge channel.
[0005] Furthermore, both the feeding quantitative conveying mechanism and the discharging quantitative conveying mechanism are screw feeders.
[0006] Furthermore, the scraping and arch-breaking mechanism includes a drive motor, a reducer, a connecting seat, a rotating ring seat, and a scraper plate; the rotating ring seat is rotatably connected to the interior of the connecting seat, the drive motor and the reducer are fixedly connected to one side of the connecting seat, the input end of the reducer is drivenly connected to the drive motor, and the output end of the reducer is drivenly connected to the rotating ring seat through a transmission gear; the top and bottom of the connecting seat are both provided with connecting flanges; the bottom of the scraper plate is fixedly connected to the inner sidewall of the rotating ring seat.
[0007] Furthermore, the lower part of the hopper gradually narrows to form a conical structure towards the discharge port, the bottom of the scraper is a vertical plate, the upper part of the scraper is bent outward, and the upper part of the scraper is parallel and spaced apart from the inner wall of the discharge port of the hopper.
[0008] Furthermore, the material level sensor located below is positioned above the top of the scraper plate.
[0009] Furthermore, a manual slide valve is also connected between the scraping and arch-breaking mechanism and the inlet end of the discharge quantitative conveying mechanism.
[0010] Furthermore, the silo is equipped with several vibrating hammers around its perimeter.
[0011] Furthermore, a manual feed port is also provided on the top of the hopper.
[0012] The beneficial effects of this utility model are: 1) This utility model scrapes the material at the discharge port through the scraping and arch-breaking mechanism, which can prevent the material from arching and blocking at the outlet of the silo and has a smooth material discharge function. At the same time, the material level sensor monitors the material level in real time to control the feeding and discharging, thus solving the problem of silo overflow and blockage.
[0013] 2) The lower level sensor monitors the lower limit of the material level in silo 1, while the upper level sensor monitors the upper limit. If both sensors trigger an empty material signal, the conveying operation of the discharge metering conveyor will be slowed down or stopped, while the conveying operation of the infeed metering conveyor will be accelerated. If only the lower sensor triggers an empty material signal without triggering the upper sensor, it indicates a blockage at the top of the silo. In this case, both the infeed and discharge metering conveyors will be stopped, awaiting manual intervention. If both sensors trigger a blockage signal, it indicates that the silo has overflowed. In this case, both the infeed and discharge metering conveyors will be stopped, awaiting manual intervention.
[0014] 3) The vibrating hammer intermittently vibrates the upper part of the silo, which can shake off the material that is caking on the inner wall of the silo. Combined with the scraping and arch-breaking mechanism, it can solve the problem of material blockage in the silo. Attached Figure Description

[0019] Reference Figures 1 to 2 As shown, a stable feeding device for a silo includes a silo 1, a feeding quantitative conveying mechanism 2, a discharging quantitative conveying mechanism 3, a material level detection mechanism 4, and a scraping and arch-breaking mechanism 5. The silo 1 has a feed inlet 11 at its top, one end of which is connected to the outlet end of the feeding conveying mechanism 2. The silo 1 has a discharge outlet 12 at its bottom. The material level detection mechanism 4 includes two material level sensors 41 installed vertically and horizontally on the silo 1. The scraping and arch-breaking mechanism 5 is installed at the discharge outlet 12, with its top connected to the outlet 12 and its bottom connected to the inlet end of the discharging quantitative conveying mechanism 3. The scraping and arch-breaking mechanism 5 has a discharge channel 541, and a scraper 55 rotating along the discharge outlet 12 and the lower inner wall of the silo 1 is installed within the discharge channel 541. Specifically... Both the feeding quantitative conveying mechanism 2 and the discharging quantitative conveying mechanism 3 are screw conveyors. The screw conveyors provide stable conveying speeds and can mix and stir materials during conveying, meeting the requirements for quantitative feeding. The rotating scraper plate 55 on the scraper and anti-arching mechanism 5 resolves arching at the bottom of the silo, preventing material blockage at the outlet and ensuring smooth material flow into the discharging quantitative conveying mechanism 3. The lower level sensor monitors the lower limit of the material level in the silo 1, while the upper level sensor monitors the upper limit. If both level sensors trigger an empty material signal, the discharging quantitative conveying mechanism's conveying operation is slowed or stopped, while the feeding quantitative conveying mechanism's conveying operation is accelerated. If only the lower sensor triggers an empty material signal without triggering the upper sensor, it indicates a blockage at the top of the silo. In this case, both the feeding and discharging quantitative conveying mechanisms are stopped, awaiting manual intervention. If both the upper and lower level sensors trigger a blockage signal, the surface silo has already overflowed. At this point, both the feeding and discharging metering mechanisms 2 and 3 should be stopped simultaneously, awaiting manual intervention. Therefore, to solve the problem of blockage at the top of the silo, this invention includes several vibrating hammers 6 around the silo 1, intermittently vibrating the upper part of the silo 1 to dislodge material clumps on the inner wall, thus preventing blockage. This invention also uses a scraping and arch-breaking mechanism to scrape material from the discharge port, preventing arching and blockage at the silo outlet, ensuring smooth material discharge. Simultaneously, level sensors monitor the material level in real time to control feeding and discharging, resolving the silo overflow and blockage problem.
[0020] The scraping and arch-breaking mechanism 5 includes a drive motor 51, a reducer 52, a connecting seat 53, a rotating ring seat 54, and a scraper 55. The rotating ring seat 54 is rotatably connected to the interior of the connecting seat 53. The drive motor 51 and the reducer 52 are fixedly connected to one side of the connecting seat 53. The input end of the reducer 52 is driven by the drive motor 51, and the output end of the reducer 52 is driven by the rotating ring seat 54 through a transmission gear. The top and bottom of the connecting seat 53 are both provided with connecting flanges. The lower part of the hopper 1 gradually narrows to the discharge port 12 to form a conical structure. The bottom of the scraper 55 is a vertical plate, and the upper part of the scraper 55 is bent outward. The upper part of the scraper 55 is parallel and spaced apart from the inner wall of the discharge port 12 of the hopper 1. The scraping and arch-breaking mechanism 5 is fixedly connected to the discharge port 12 via a connecting flange. The inner circular hole of the rotating ring seat 54 is the discharge hole. The bottom of the scraper plate 55 is fixedly connected to the inner side wall of the rotating ring seat 54. The drive motor 51 drives the rotating ring seat 54 to rotate along the connecting seat 53 via the reducer 52, thereby driving the scraper plate 55 to rotate along the discharge port 12 and the lower inner wall of the hopper 1, stirring the material at the discharge port and the lower part of the hopper, and preventing arching at the discharge port 12 of the hopper 1. The connecting seat 53 and the rotating ring seat 54 are sealed with a sealing ring to prevent material from entering the mechanism. The specific internal structure of the scraping and arch-breaking mechanism can be referred to in Chinese Patent CN201721572209.0, which discloses an arch-breaking device for breaking arched materials at the discharge port. This is prior art and will not be described in detail here.
[0021] The material level sensor 41 located below is positioned above the top of the scraper plate 55 to avoid interfering with the movement trajectory of the scraper plate 55. A manual slide valve 7 is also connected between the scraper arch breaking mechanism 5 and the inlet end of the discharge quantitative conveying mechanism 3, which can manually control the discharge. The top of the hopper 1 is also provided with a manual feed port 13, which can be used for manual intervention.
[0022] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
