Description

Technical Field

[0001] This utility model relates to the field of storage equipment technology, and in particular to a silo arch-breaking device. Background Technology

[0002] Feed ingredients are important materials in the feed production industry. They are stored in storage silos for centralized management and retrieval. Storage silos are key equipment in the storage and production of feed ingredients.

[0003] During the long-term storage and gravity discharge of feed ingredients, due to the physical characteristics of the feed ingredients themselves, such as moisture, particle size, static friction coefficient and storage pressure, cohesive forces will be generated between feed ingredient particles, and frictional forces will be generated with the inner wall of the silo. When these forces reach a certain level near the conical discharge port at the bottom of the silo, the feed ingredients (especially powdery or near-powdery ingredients) will form a self-supporting arch structure above the discharge port. This arching phenomenon will prevent the feed ingredients in the silo from falling normally by gravity, causing the feed ingredients to be unable to be discharged normally from the discharge port, thus interrupting the continuity of production.

[0004] In existing technologies, mechanical vibration devices or air hammers are used to strike the silo wall to solve the arching problem, or manual poking is used. However, mechanical vibration is not effective in breaking up solid arches, and long-term vibration will damage the silo structure itself. Air hammers have a single point of impact, a limited range of arch breaking, and generate huge noise pollution. Manual poking is not only labor-intensive and inefficient, but also poses serious safety hazards.

[0005] Therefore, this utility model proposes a silo arch-breaking device to address the shortcomings of the prior art. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0032] Example:

[0033] Please refer to Figures 1 to 8 This utility model provides a storage silo arch-breaking device, which aims to solve the problem of feed raw materials in storage silos easily forming arches, resulting in poor material discharge in the prior art.

[0034] Please refer to Figure 1 , Figure 2 and Figure 6The storage silo arch-breaking device includes a storage silo 1 for storing feed ingredients. The bottom end of the storage silo 1 is connected to a discharge port 5 for discharging the feed ingredients. The storage silo arch-breaking device also includes an arch-breaking mechanism 2, which is installed through the side wall of the storage silo 1 and is used to break up the arches of the feed ingredients. The storage silo arch-breaking device also includes a heating mechanism 3, which includes a threaded interface 31 and a cylindrical heater 33. The threaded interface 31 is threadedly connected to the end of the storage tank 21 away from the rupture disc 24. The cylindrical heater 33 is located at the other end of the threaded interface 31. Multiple cylindrical heaters 33 are provided (e.g., 4 to 5), and the multiple cylindrical heaters 33 are connected through and fixed to the base 38. The heating mechanism 3 is used to heat the arch-breaking mechanism 2. The arch-breaking device of the storage silo also includes a transmission mechanism 4, which includes a high-temperature wire 37 and a power distribution cabinet 45. The output end of the high-temperature wire 37 is electrically connected to the input end of the cylindrical heater 33 (the high-temperature wire 37 is connected to the cylindrical heater 33 through a connector lug: the round hole end of the connector lug is connected to the high-temperature wire 37, and the lug end is connected to the metal lead-out rod of the cylindrical heater 33 through a stainless steel nut). The power distribution cabinet 45 is electrically connected to the input end of the high-temperature wire 37. The transmission mechanism 4 is used to provide power and control the entire arch-breaking process. The storage silo 1 is used to store feed raw materials and serves as the mounting carrier for the arch-breaking mechanism 2, the discharge port 5, the heating mechanism 3, and the transmission mechanism 4.

[0035] Please refer to Figure 3 and Figure 4 The arch-breaking mechanism 2 includes a storage tank 21, which is used to store liquid carbon dioxide. Under normal room temperature conditions, the liquid pressure of carbon dioxide is 6 MPa, and at 31°C, the liquid pressure of carbon dioxide is about 7.5 MPa. Therefore, the pressure that the storage tank 21 needs to withstand can be set between 15 and 20 MPa. At 45°C, the liquid pressure of carbon dioxide can reach 12 MPa. Therefore, in high-temperature areas in the south, the pressure that the storage tank 21 needs to withstand is 20 MPa or higher. Thus, a suitable liquid carbon dioxide storage tank 21 can be selected according to different temperatures. One end of the storage tank 21 is threaded with an inlet flange 22, and the other end of the inlet flange 22 is threaded with an outlet flange 26 via a connecting screw 27. The inlet flange 22 and the outlet flange 26 pass through and fix the arch-breaking mechanism 2 to the side wall of the storage silo 1. Gasket 1 23 and gasket 25 are provided between the inlet flange 22 and the outlet flange 26. A rupture disc 24 is clamped between gasket 1 23 and gasket 25. The threshold of the rupture disc 24 can be selected as 12MPa or selected according to different temperatures and needs. When the internal pressure of the storage tank 21 reaches the threshold, the rupture disc 24 ruptures, and high-pressure carbon dioxide gas is ejected from the outlet flange 26. The rupture disc 24 is clamped between the inlet flange 22 and the outlet flange 26. The flanges are tightened by bolts and nuts, thereby compressing the rupture disc 24. This connection has good sealing performance, high pressure resistance, and higher safety.

[0036] Please refer to Figure 5 and Figure 6 To heat the arch-breaking mechanism 2, the heating mechanism 3 is connected to the end of the storage tank 21 furthest from the rupture disc 24. Specifically, a threaded interface 31 is threadedly connected to the end of the storage tank 21 furthest from the rupture disc 24. When the threaded interface 31 is fully tightened to the storage tank 21, it forms a seal with the bottom of the storage tank 21 to prevent heat leakage. A thermally conductive silicone 32 is provided at the other end of the threaded interface 31, and this silicone 32 is attached to a cylindrical heater 33. Multiple cylindrical heaters 33 are provided, and different numbers can be selected according to temperature requirements. These multiple cylindrical heaters 33 are used to generate heat. An insulating layer 34 is provided around the outer periphery of the cylindrical heater 33. One end of the insulating layer 34 abuts against the threaded interface 31, and the other end abuts against the base 38. It forms a sealed space around the cylindrical heater 33 to prevent heat loss. The outer wall of the insulating layer 34 is provided with a heat insulation shell 35. High-temperature resistant glass fiber cotton is filled between the insulating layer 34 and the heat insulation shell 35 to play a heat insulation role and prevent heat loss. A temperature sensor 36 is provided at the top of the heat insulation shell 35. The probe of the temperature sensor 36 is located in the internal space enclosed by the insulating layer 34. The signal end of the temperature sensor 36 is electrically connected to the transmission mechanism 4 to provide feedback on the real-time temperature generated by the cylindrical heater 33.

The outer wall of the insulating layer 34 is provided with a heat insulation shell 35, which forms a sealed outer cover that completely wraps the insulating layer 34 and the cylindrical heater 33 inside. High-temperature resistant glass fiber cotton is filled between the insulating layer 34 and the heat insulation shell 35 to further play a role in heat preservation.

[0041] As a preferred embodiment, for real-time monitoring and temperature feedback of the heating process, please refer to... Figure 6 A temperature sensor 36 is provided at the top of the insulation shell 35. The probe of the temperature sensor 36 is located in the internal space enclosed by the insulation layer 34. The signal end of the temperature sensor 36 is electrically connected to the transmission mechanism 4, which transmits the temperature data generated by the cylindrical heater 33 to the control system in real time.

[0042] As a preferred embodiment, to achieve a reliable connection between the high-temperature conductor 37 and the external control signal, please refer to... Figure 7 and Figure 8 The high-temperature wire 37 is connected to an aviation plug 41 at its input end.

The input end of the aviation plug 1 41 is pluggably connected to the aviation plug 2 43 by means of a plug-in connection, so that the connection between the high temperature wire 37 and the external power supply can be quickly separated and connected.

[0044] As a preferred embodiment, to protect the external cable and ensure safe introduction into the transmission mechanism 4, please refer to... Figure 7 and Figure 8 The transmission mechanism 4 also includes a cable gland 44. The input end of the aviation plug 43 is provided with a cable gland 44. The input end of the cable gland 44 is connected to the distribution cabinet 45 for fixing and sealing the introduced cable.

[0045] As a preferred embodiment, in order to achieve precise control of the heating process, please refer to... Figure 1 A temperature controller 46 is installed on the outer wall of the power distribution cabinet 45. The temperature controller 46 is electrically connected to the power distribution cabinet 45 and is used to adjust the power output to the cylindrical heater 33 in real time according to the feedback signal of the temperature sensor 36, thereby controlling the temperature of the cylindrical heater 33.

[0046] Working Principle: When the feed raw materials in the storage silo 1 clump together, obstructing the normal discharge from the discharge port 5, the operator activates the anti-clumping program by operating the temperature controller 46 on the distribution cabinet 45. The distribution cabinet 45 sends an electrical signal, which is first safely introduced through the cable gland 44 and then transmitted to the aviation plug 2 43. The aviation plug 2 43 is detachably connected to the aviation plug 1 41, further transmitting the electrical signal to the aviation plug 1 41. The connection slot 42 of the aviation plug 1 41 accurately guides the electrical signal to the input end of the matching high-temperature wire 37. After receiving the electrical energy, the high-temperature wire 37 transmits the output energy to the input end of the cylindrical heater 33. At this time, the cylindrical heater 33 begins to generate heat. The heat generated by the cylindrical heater 33 is absorbed by the thermally conductive silicone 32 tightly adhered to its surface. The heat is efficiently transferred to the threaded interface 31, which is threaded to one end of the storage tank 21. The heat can be transferred to the storage tank 21 through the threaded interface 31, and finally to the liquid carbon dioxide stored inside the storage tank 21. As the temperature of the liquid carbon dioxide in the storage tank 21 rises, it vaporizes rapidly, causing the internal pressure of the storage tank 21 to rise sharply. When the pressure inside the storage tank 21 reaches the threshold of the rupture disc 24, the rupture disc 24 clamped between the gasket 1 23 and the gasket 25 breaks instantly. The high-pressure carbon dioxide gas is ejected at high speed from the outlet flange 26, directly impacting the arched feed material inside the storage silo 1. The powerful impact breaks down the arch of the feed material, restoring the feed material to a flowing state so that the feed material can be smoothly discharged from the storage silo 1 through the discharge port 5.

[0047] Meanwhile, the outer periphery of multiple cylindrical heaters 33 is enclosed and isolated by an insulating layer 34. The outer wall of the insulating layer 34 is provided with a heat-insulating shell 35. The temperature sensor 36 installed at the top of the heat-insulating shell 35 feeds back the real-time temperature signal of the internal space enclosed by the insulating layer 34 to the transmission mechanism 4 through the signal terminal. The temperature controller 46 in the transmission mechanism 4 is electrically connected to the power distribution cabinet 45 and is used to adjust the power output to the cylindrical heaters 33 in real time according to the feedback signal of the temperature sensor 36, thereby controlling the temperature of the cylindrical heaters 33 and ensuring precise control of the heating process.

[0048] The silo arch-breaking device in this application can be used not only for breaking up arches of feed raw materials, especially powdery or near-powdered feed raw materials, but also for breaking up arches of other powdery materials that are prone to arching.
