Energy storage type anti-blocking structure of feed bin

Abstract

This utility model discloses an anti-clogging structure for an energy storage feeding silo, relating to the field of feeding silo technology. It includes a feeding silo and a support frame. Several anti-clogging components and vibrators are arranged around the feeding silo. A discharge hopper is located below the feeding silo, and an anti-clogging assembly is also located below the support frame. The anti-clogging assembly uses a stirring paddle to prevent the discharge hopper from clogging. The feeding silo is wider at the top and narrower at the bottom, and all four walls of the feeding silo are inclined. The vibrators are centrally installed on the four walls of the feeding silo. This utility model integrates vibration anti-sticking, directional airflow arch breaking, and mechanical agitation technologies. The inclined silo walls and inner mesh screening optimize gravity flow. The centrally located vibrators use high-frequency micro-vibration to break the adhesive layer on the silo wall. The anti-clogging components utilize pulsed high-pressure airflow to precisely cut the root of the material arch. The dual-stirring paddle counter-rotating design, combined with an external bearing seat, not only powerfully breaks up compacted clumps at the discharge port but also facilitates maintenance.

Description

Technical Field

[0001] This utility model relates to the field of feeding bin technology, specifically to an energy storage feeding bin anti-clogging structure. Background Technology

[0002] In continuous industrial production systems, material blockage in the material conveying process has long constrained production efficiency and safety. Especially in industries such as coal, grain processing, metallurgy, and chemicals, high-humidity, high-viscosity, or easily arching powdery and granular materials frequently cause silo wall adhesion, material arching blockage, and discharge port compaction in traditional feeding silos. This not only leads to production line shutdowns for clearing blockages but also causes equipment overload, a surge in energy consumption, and the risk of manual intervention.

[0003] Existing single anti-clogging technologies, such as pure vibration, lack sufficient depth of action, while mechanical agitation devices are often difficult to maintain and thus hinder widespread adoption. Against this backdrop, there is an urgent need for an innovative structure that integrates multi-stage anti-clogging mechanisms while balancing energy efficiency and reliability, to ensure smooth material flow from the bin walls to the discharge port, supporting the intelligent and low-consumption development needs of modern industry.

[0004] Therefore, this utility model constructs a full-process anti-blocking system through a three-level synergy of vibration anti-sticking, pulse air knife arch breaking and mechanical stirring. Thus, this utility model proposes a novel solution. Utility Model Content

[0005] The purpose of this invention is to provide an energy storage feeding silo anti-blocking structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model utilizes the air box at the top of the main frame of the feeding silo as an air energy storage structure. The anti-blocking component is connected to the air box on the silo wall via a pipeline. A normally closed solenoid valve is installed on the pipeline. The air box is welded to the silo wall, and a rectangular slot is opened in the silo wall at the corresponding position of the air box. A baffle is welded inside the silo wall to change the airflow direction.

[0007] A clog-prevention structure for an energy storage feed hopper includes:

[0008] Feed hopper, support frame, and anti-clogging components;

[0009] The anti-clogging component includes a bend, one end of which is fixed with a connecting pipe, and the other end of which is installed on the wall of the feeding hopper through a rectangular box. An air box is fixed at the end of the bend away from the rectangular box, and the air box is hidden in the crossbar of the support. A solenoid valve is also installed on the bend.

[0010] Each rectangular box in the feeding bin has a through hole, and each rectangular box in the feeding bin is also fixed with a baffle. The baffle is tilted to guide the airflow.

[0011] When feeding material or when a blockage such as material arching is predicted in the lower part of the feeding hopper (in conjunction with sensors), the corresponding solenoid valve is activated. High-pressure gas is injected into the hopper through the bend and connecting pipe, from the rectangular box through the through-holes in the hopper wall. The inclined baffle guides this high-speed airflow to impact the material on the hopper wall at a specific angle, reducing adhesion to the hopper wall. The inclined baffle effectively guides the airflow direction, so that it does not impact the material vertically or randomly, but impacts along the inclined surface of the hopper wall that is prone to blockage, directly acting on the key areas where material arching or adhesion occurs. The effect of breaking arches and clearing blockages is more precise and efficient, concentrating the airflow energy in the direction of the wall surface that needs the most impact, avoiding energy waste in ineffective space.

[0012] Furthermore, the feeding hopper is wider at the top and narrower at the bottom, and all four walls of the feeding hopper are inclined. Anti-blocking components are also installed on the four walls of the feeding hopper.

[0013] Furthermore, the baffle is welded to the four sides of the feeding hopper, and the baffle forms an angle of 15°-45° with the inner wall of the feeding hopper.

[0014] Further, the top of the support is a ring of interconnected hollow tubes. The solenoid valve of each anti-clogging component is connected to the hollow tube through the tube body. The hollow tube is connected to a pressure boosting tube to pressurize the inside of the hollow tube.

[0015] Further, the baffle includes an arc-shaped portion that covers the through hole, and the end of the arc-shaped baffle is a straight plate, which is parallel to the inner wall of the feeding hopper and has a gap with the inner wall.

[0016] Furthermore, an inner net is installed at the feeding hopper, which is parallel to the ground and fixed to the four walls of the feeding hopper.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This energy storage feeding silo anti-clogging structure integrates three technologies: vibration anti-sticking, directional airflow arch breaking, and mechanical agitation. The inclined silo wall and inner mesh screening optimize gravity flow. The centrally located vibrator uses high-frequency micro-vibration to break the adhesive layer on the silo wall. The anti-clogging component uses pulsed high-pressure airflow to precisely cut the root of the material arch. The dual stirring paddles rotating in opposite directions, combined with the external bearing seat, can not only powerfully break up the compacted clumps at the discharge port, but also facilitate maintenance.

[0019] Meanwhile, the structure achieves a balance between energy consumption and efficiency: the pneumatic-electric time-sharing working mode avoids energy waste, the combination of pulse solenoid valve and variable frequency drive motor can reduce overall energy consumption, and the compact design hides the air box in the support crossbar and the bearing seat is external, which saves space and facilitates quick maintenance.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 As shown, this utility model provides a technical solution: an energy storage feeding silo anti-clogging structure, comprising:

[0028] Feeding hopper 2, support frame 1, and anti-blocking component 5;

[0029] The anti-blocking component 5 includes a bend 501, one end of which is fixed with a connecting pipe 502, and the other end of the connecting pipe 502 is installed on the wall of the feeding bin 2 through a rectangular box 503. An air box 506 is fixed at the end of the bend 501 away from the rectangular box 503. The air box 506 is hidden in the crossbar of the support 1. A solenoid valve 505 is also provided on the bend 501.

[0030] Each rectangular box 503 in the feeding bin 2 has a through hole, and each rectangular box 503 in the feeding bin 2 is also fixed with a baffle 504. The baffle 504 is inclined to guide the airflow.

[0031] When feeding material or when a blockage such as material arching is predicted in the lower part of the feeding bin 2 (in conjunction with a sensor), the corresponding solenoid valve 505 is activated. High-pressure gas is injected into the bin through the through-hole on the bin wall from the rectangular box 503 via the bend 501 and connecting pipe 502. The inclined baffle 504 guides this high-speed airflow to impact the material on the bin wall at a specific angle, reducing adhesion to the bin wall. The inclined baffle 504 can effectively guide the airflow direction, so that it does not impact the material vertically or randomly, but impacts along the inclined surface of the bin wall that is prone to blockage, directly acting on the key areas where material arching or adhesion occurs. The effect of breaking arches and clearing blockages is more precise and efficient, concentrating the airflow energy in the direction of the wall surface that needs to be impacted the most, avoiding energy waste in ineffective space.

[0032] To ensure the smooth implementation of this embodiment, it is necessary to understand that the feeding bin 2 is wider at the top and narrower at the bottom, and the four walls of the feeding bin 2 are all inclined. The anti-blocking component 5 is also installed on the four walls of the feeding bin 2.

[0033] To ensure the smooth implementation of this embodiment, it is necessary to understand that the baffle 504 is welded to the four sides of the feeding bin 2, the tail end of the baffle 504 is parallel to the inner wall of the feeding bin 2, and the baffle 504 forms an angle of 0°-45° with the inner wall of the feeding bin 2 with the welding point as the reference.

[0034] To ensure the smooth implementation of this embodiment, it is necessary to understand that the top of the support 1 is a ring of interconnected hollow tubes 101, and the solenoid valve 505 of each anti-blocking component 5 is connected to the hollow tube 101 through the tube body. The hollow tube 101 is connected to a pressure boosting pipe 6 to pressurize the inside of the hollow tube 101.

[0035] As one embodiment of the above embodiments, a booster pipe 6 is connected to each air box 506, and the booster pipe 6 is connected to an air compressor.

[0036] To ensure the smooth implementation of this embodiment, it is necessary to understand that the baffle 504 includes an arc-shaped portion that covers the through hole, and the end of the arc-shaped plate is a straight plate. The straight plate is parallel to the inner wall of the feeding bin 2 and has a gap with the inner wall. The gap between the straight plate at the end and the bin wall allows the airflow, which has been initially guided and accelerated, to be further adjusted here, forming an airflow layer that is closer to the wall and more evenly distributed. This allows for continuous and larger-area "blowing" of the wall material, rather than just point impact, resulting in more thorough clearing of blockages. The arc-shaped portion covering the through hole effectively prevents the material above from falling directly and impacting or blocking the jet nozzle, improving the reliability of the system and reducing the intensity of dust to a certain extent.

[0037] To ensure the smooth implementation of this embodiment, it is necessary to understand that an inner net 3 is installed at the feeding hopper 2. The inner net 3 is parallel to the ground and fixed to the four walls of the feeding hopper 2. By blocking large pieces of material, the possibility of blockage at the bottom of the feeding hopper 2 is significantly reduced. This allows the anti-blocking component 5 to mainly deal with the arching or wall adhesion problems of relatively fine particles, thereby improving the efficiency and service life of the entire anti-blocking system and reducing the pressure and load at the unloading hopper 4.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
