Technical Field
[0001] This utility model relates to the technical field of powder material processing equipment, specifically a pulse jet blowing arch-breaking device. Background Technology
[0002] In the powder material handling industry, the problem of sticky powder sticking to the walls and arching in the silo has long restricted the continuous and stable operation of the production line, becoming a technical pain point that urgently needs to be solved in the industry. Traditional arch breaking and flow aid solutions are mainly divided into three categories: mechanical vibration, loosening air aid, and flow aid air disc, but all of them have obvious technical problems. Traditional devices for eliminating the arching of sticky powders often employ mechanical vibration or the introduction of loosening air. However, for highly viscous and hygroscopic materials, these methods are unlikely to be effective in breaking up arches and promoting flow. Furthermore, the flow-aiding air discs commonly used in current engineering projects require disassembly and replacement if they malfunction, which is time-consuming and labor-intensive. Over time, this leads to material accumulation and adhesion to the inner walls, ultimately necessitating manual cleaning. This causes significant disruption to continuous automated production lines and the working environment for personnel. From the perspective of mechanical vibration equipment, such as vibratory motors, air hammers, and vibrators, the core principle is to destroy the structural stability of material arches through high-frequency mechanical vibration or impact. However, in practical applications, such equipment will generate high-intensity working noise, causing serious noise pollution to the working environment at the production site and affecting the physical and mental health of operators. Long-term hard mechanical collisions and high-frequency vibrations can easily damage the structure of the silo and its supporting equipment, leading to frequent failures such as cracked welds and loose connections in the silo. This significantly increases the equipment's operation and maintenance costs and the frequency of downtime for repairs. Especially for large powder processing production lines, the capacity loss caused by downtime is incalculable. To address the aforementioned problems, a pulse jet arch-breaking device needs to be designed. Utility Model Content
[0003] The purpose of this invention is to provide a pulse jet arch-breaking device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a pulse jet arch-breaking device, comprising a hopper, a jet ring pipe fixedly connected to the center of the periphery of the hopper, a first connecting pipe fixedly connected to the periphery of the jet ring pipe, a pulse jet arch-breaking mechanism provided around the hopper, and an air supply mechanism provided around the hopper. The pulse jet arch-breaking mechanism includes a mounting base, which is fixedly connected to the inside of the hopper. A valve body is threadedly connected inside the mounting base, and a valve stem is slidably connected inside the valve body. A locking nut is threadedly connected to the outside of the valve body and is located on the right side of the mounting base. An electromagnetic pulse valve is threadedly connected to the outside of the right end of the valve body. A sliding sleeve is slidably connected to the outside of the valve stem. A spring seat is slidably connected to the outside of the right end of the valve stem. An anti-loosening nut is threadedly connected to the outside of the right end of the valve stem and is located on the right side of the spring seat. A compression spring is sleeved around the outside of the valve stem.
[0005] Preferably, the left side of the locking nut is in contact with the right side of the mounting base, and the first connecting pipe is provided in six sets, which are respectively located around the blow ring pipe, so as to further ensure the stability between the valve body and the hopper through the locking nut.
[0006] Preferably, the sliding sleeve is fixedly connected to the valve body, and the left side of the anti-loosening nut is in contact with the right side of the spring seat, so that the sliding sleeve can guide the valve stem.
[0007] Preferably, the left side of the compression spring is fixedly connected to the right side of the sliding sleeve, the right side of the compression spring is fixedly connected to the left side of the spring seat, and the bottom of the pulse solenoid valve is fixedly connected to the top of the first connecting pipe, so as to facilitate the delivery of airflow into the pulse solenoid valve through the first junction pipe.
[0008] Preferably, the mounting base, valve body, valve stem, locking nut, sliding sleeve, compression spring, spring seat, anti-loosening nut, and electromagnetic pulse valve are provided in six sets, with three sets located on the upper part of the outer perimeter of the hopper and three sets located on the lower part of the outer perimeter of the hopper. This arrangement of six sets allows for precise application to material arches at different heights and in different areas within the hopper, avoiding the blind spots in arch breaking that exist with traditional single-position spraying.
[0009] Preferably, the air supply mechanism includes a mounting frame, which is fixedly connected to the periphery of the silo. An air storage tank is fixedly connected to the periphery of the mounting frame. An air inlet pipe is fixedly connected to the front side of the air storage tank. An air outlet pipe is fixedly connected to the left side of the air storage tank. A second connecting pipe is fixedly connected to the periphery of the air outlet pipe.
[0010] Preferably, the second connecting pipe is fixedly connected to the periphery of the jet ring pipe, which facilitates the delivery of airflow into the jet ring pipe through the second connecting pipe.
[0011] Compared with the prior art, this utility model provides a pulse jet arch-breaking device, which has the following beneficial effects: This pulse jet anti-bridging device, through its specially designed pulse jet anti-bridging mechanism, eliminates the arching of sticky powder within the silo. Six sets of core components, including the mounting base and valve body, are arranged: three sets located on the upper perimeter of the silo, and three sets on the lower perimeter. These, along with the jet ring pipe in the center of the silo and the six sets of first connecting pipes, form a multi-directional jet coverage. This allows for precise targeting of material arches at different heights and in different areas within the silo, avoiding the blind spots inherent in traditional single-position jet cleaning. When material begins to form bridging in the upper part of the silo or blockage occurs in the lower part, the corresponding electromagnetic pulse valve responds quickly, directly impacting the weak points of the arch with pulsed airflow to rapidly break up and clear the blockage. Compared to traditional anti-bridging methods, this reduces response time, improves material flow efficiency, and is adaptable to various applications. In most cases of arching of viscous powders and even slurries, this device uses a pulsed high-pressure airflow to trigger a mechanical mechanism. The high-pressure airflow is guided by the valve stem cone and sprayed onto the wall to break up the arched material. This can precisely target and break up the arched area, effectively solving the industry pain point of difficulty in breaking up highly viscous and hygroscopic materials. It ensures that the powder material flows smoothly into downstream equipment and maintains the continuity of material flow in the production line. Compared with traditional mechanical vibration and air hammer impact arch-breaking equipment, this device uses compressed air to achieve arch-breaking, without hard mechanical collisions and high-frequency vibrations. This can significantly reduce structural damage to the silo and related supporting equipment during the arch-breaking process, and avoid equipment failures such as weld cracking and component loosening caused by long-term vibration. The pulse width and interval can be adjusted to adapt to the arch-breaking of different materials to achieve the best arch-breaking effect.
[0012] This pulse jet arch-breaking device, through its air supply mechanism, has a mounting frame fixed to the outside of the silo. The air storage tank, acting as a pressure stabilizing unit, can store sufficient compressed air and maintain stable pressure. The air inlet pipe is responsible for continuous air replenishment, while the air outlet pipe and the second connecting pipe deliver the stable pressure airflow to the jet ring pipe, ensuring that all six sets of first connecting pipes receive a uniform and sufficient air source. This independent air supply system avoids the problem of unstable jet effect caused by air source pressure fluctuations. The pressure of the air storage tank can be adjusted according to the material characteristics to achieve precise control of the jet intensity. This ensures effective impact on the hard arch frame while avoiding material splashing or silo damage due to excessive pressure, thus improving the stability and applicability of the device.

[0017] This utility model provides the following technical solution: Example 1
[0018] Please see Figure 1-5 This utility model provides a technical solution: a pulse jet arch breaking device, including a hopper 1, a jet ring pipe 2 fixedly connected to the center of the outer periphery of the hopper 1, a first connecting pipe 4 fixedly connected to the outer periphery of the jet ring pipe 2, a pulse jet arch breaking mechanism 3 arranged around the hopper 1, and an air supply mechanism 5 arranged around the hopper 1. The pulse jet arch-breaking mechanism 3 includes a mounting base 31, which is fixedly connected to the inside of the hopper 1. A valve body 32 is threadedly connected inside the mounting base 31, and a valve stem 33 is slidably connected inside the valve body 32. A locking nut 34 is threadedly connected to the outside of the valve body 32 and is located on the right side of the mounting base 31. An electromagnetic pulse valve 39 is threadedly connected to the outside of the right end of the valve body 32. A sliding sleeve 35 is slidably connected to the outside of the valve stem 33. A spring seat 37 is slidably connected to the outside of the right end of the valve stem 33. An anti-loosening nut 38 is threadedly connected to the outside of the right end of the valve stem 33 and is located on the right side of the spring seat 37. A compression spring 36 is sleeved around the outside of the valve stem 33.
[0019] The left side of the locking nut 34 is in contact with the right side of the mounting base 31. The first connecting pipe 4 is provided with six sets, which are located on the periphery of the spray ring pipe 2, so as to further ensure the stability between the valve body 32 and the hopper 1 through the locking nut 34.
[0020] The sliding sleeve 35 is fixedly connected inside the valve body 32. The left side of the anti-loosening nut 38 is in contact with the right side of the spring seat 37, so that the sliding sleeve 35 can guide the valve stem 33.
[0021] The left side of the compression spring 36 is fixedly connected to the right side of the sliding sleeve 35, and the right side of the compression spring 36 is fixedly connected to the left side of the spring seat 37. The bottom of the pulse solenoid valve is fixedly connected to the top of the first connecting pipe 4, so as to facilitate the delivery of airflow into the pulse solenoid valve through the first junction pipe.
[0022] The mounting base 31, valve body 32, valve stem 33, locking nut 34, sliding sleeve 35, compression spring 36, spring seat 37, anti-loosening nut 38, and electromagnetic pulse valve 39 are provided in six sets, with three sets located on the upper part of the outer perimeter of the hopper 1 and three sets located on the lower part of the outer perimeter of the hopper 1. By setting six sets, it is possible to accurately act on the material arches of different heights and areas within the hopper 1, avoiding the blind spots of arch breaking that exist in traditional single-position spraying. Example 2
[0023] Please see Figure 1-5 Furthermore, based on Embodiment 1, the air supply mechanism 5 includes a mounting frame 52, which is fixedly connected to the periphery of the silo 1. An air storage tank 51 is fixedly connected to the periphery of the mounting frame 52. An air inlet pipe 53 is fixedly connected to the front side of the air storage tank 51. An air outlet pipe 54 is fixedly connected to the left side of the air storage tank 51. A second connecting pipe 55 is fixedly connected to the periphery of the air outlet pipe 54.
[0024] The second connecting pipe 55 is fixedly connected to the periphery of the jet ring pipe 2, so as to facilitate the delivery of airflow into the jet ring pipe 2 through the second connecting pipe 55.
[0025] In actual operation, when this device is used, when it is necessary to eliminate the arching of sticky powder in the silo 1, first connect the six sets of electromagnetic pulse valves 39 to the same external pulse controller to achieve centralized control. The pulse controller regulates the orderly action of the pulse jet breaking mechanism 3, and the powder material is broken by high-pressure airflow guiding the wall-mounted jet. At the same time, the external air supply pipe is connected to the air inlet pipe 53, so that the gas enters the air storage tank 51 to complete the high-pressure gas storage. The high-pressure air in the air storage tank 51 is then transported to the second pipe 55 through the air outlet pipe 54, and finally flows into the spray ring pipe 2 in the middle of the outer periphery of the silo 1, providing a stable high-pressure air source for the six sets of pulse spray arch breaking mechanisms 3. The six sets of first pipes 4 on the outer periphery of the spray ring pipe 2 are responsible for transporting the high-pressure gas in the ring pipe to the corresponding electromagnetic pulse valves 39 to achieve precise distribution of the air source. The six sets of pulse jet arch breaking mechanisms 3 are located at the upper and lower parts of the material distribution bin 1. The electromagnetic pulse valves 39 are all controlled by the pulse controller. According to the arching characteristics of the material, the operator can preset the output sequence of the pulse signal, the pulse interval and the pulse width. When the pulse controller is powered on, it will send an electrical signal to the corresponding electromagnetic pulse valve 39 according to the set program to control the opening and closing timing and duration of the electromagnetic pulse valve 39, so as to realize the orderly triggering of the arch breaking action. When the corresponding electromagnetic pulse valve 39 receives the opening signal, the high-pressure air in the spray ring pipe 2 will enter the valve body 32 through the electromagnetic pulse valve 39. The airflow channel formed by the valve body 32 and the sliding sleeve 35 will act on one end of the valve stem 33. The impact force of the high-pressure airflow will overcome the preload of the compression spring 36 and push the valve stem 33 to slide along the sliding sleeve 35. The conical surface of the valve stem 33 will guide the high-pressure airflow to the inner wall of the lower cone of the hopper 1, realizing the precise spraying of the high-pressure airflow against the wall, directly acting on the material arching area, using the impact force of the airflow to break the material adhering to the wall arch, and ensuring the smooth falling of the powder. When the electromagnetic pulse valve 39 reaches the set opening time, the pulse controller stops outputting signals, the electromagnetic pulse valve 39 closes, and the high-pressure air supply is interrupted. At this time, the valve stem 33 resets under the elastic force of the compression spring 36, and the sealing surface of the valve stem 33 fits tightly with the sealing surface of the valve body 32, effectively blocking the reverse flow of powder material in the hopper 1 into the valve body 32 and pipeline, avoiding pipeline blockage and valve jamming. After the pulse interval time ends, the pulse controller will trigger the next set of electromagnetic pulse valves 39 to open, repeating the above blowing and reset process to achieve cyclic arch breaking. When breaking up arches, it operates with lower noise compared to conventional vibratory motors, air hammers, and vibrators, effectively reducing on-site noise pollution. Compared to conventional flow-aiding air discs, it is easier to install and maintain, requiring no disassembly of the equipment itself during maintenance, which facilitates installation and maintenance. The pulse width and interval can be adjusted to adapt to the arch breaking of corresponding materials to achieve the best arch breaking effect.
