Description

TECHNICAL FIELD

[0001] The present application relates to the field of grain storage, in particular to a multi-mode adjusted constant temperature and humidity silo. BACKGROUND

[0002] As a special form of civil engineering structure, the spiral flanging steel plate silo has been widely used in the fields of grain, feed, cement, fly ash, etc. since it was introduced into China in 1989, mainly for storage and transfer of stored materials. In the past five years, the spiral flanging steel plate silo has gradually increased its market share due to its cost, efficiency and flexibility, and has maintained at about 75%, becoming the mainstream structure form of storage. Based on the different types of stored materials, the storage requirements also have significant differences, requiring the silo to have good constant temperature, humidity and ventilation performance to reduce the storage loss caused by mold, insect damage and high temperature and humidity, and effectively ensure the safety of stored materials.

[0003] Due to the special structure of the spiral flanging steel plate silo, the existing heat preservation and ventilation methods are not suitable for this type of silo, which makes the existing silos unable to meet the long-term storage requirements, severely limiting the application of the spiral flanging steel plate silo in related industries.

[0004] The existing storage ventilation methods mainly include ground slot ventilation, radial ventilation and conical hopper ventilation. The reasons why the existing ventilation methods are not suitable for the spiral flanging steel plate silo are as follows: Ground slot ventilation, which excavates various forms of ground slots (commonly rectangular, square, V-shaped, etc.) at the bottom of the silo to form a ventilation channel to achieve ventilation, cooling and dehumidification. This method is mainly used for house silos and large and medium-sized shallow silos, and has the defects of low ventilation efficiency, existence of ventilation dead angle, slow cooling and dehumidification speed, and significant layering of stored material temperature and humidity. Based on the need for storage and the update of construction technology, the use of small and medium-sized shallow silos is gradually decreasing, and large-diameter shallow silos (d / h<1.5, where d≥24m and h≥20m) are increasing. Due to the defects of ground slot ventilation and the influence of the small range of action (mainly concentrated in the range of 8~10m from the bottom of the silo), it cannot meet the actual working conditions of high stacking of large-diameter shallow silos. Therefore, if a certain temperature and humidity are to be maintained, the ventilation time must be extended to reduce the temperature and humidity of the upper part of the stored material in the silo as much as possible. However, if the ventilation speed is too fast, the stored material will lose too much water, not only increasing the breakage rate of the stored material, but also greatly reducing the quality of the stored material (such as germination rate); if the ventilation speed is too slow, the cooling efficiency will be significantly reduced, and the cooling demand cannot be met in a short time, resulting in an increase in the mold growth rate of the stored material. At the same time, too many air ducts will significantly affect the carrying capacity of the support below the silo; too few air ducts will increase the ventilation dead angle and significantly increase the mold growth rate of the stored material. More importantly, ground slot ventilation is completely unsuitable for spiral flanging steel plate silos with steel structure support. It is basically impossible to arrange the bottom air duct on the steel structure support, and even if it is forcibly designed, it will affect the unloading and structural safety.

[0005] Radial ventilation, which needs to set multiple air ducts inside the silo, is only applicable to concrete silos. Since it is cast in situ, the formwork and layout are relatively simple. The spiral flanging steel plate silo is formed at one time, and the thickness of the steel plate is relatively small. The additional air ducts not only reduce the strength of the steel plate and affect the durability of the silo body, but also seriously threaten the safety of the silo structure. At the same time, the airflow velocity above the storage pile is generally greater than that at the bottom, and the airflow below will avoid the area with the maximum resistance at the bottom center and flow to the path with the minimum resistance, thereby causing a ventilation dead angle at the bottom. Therefore, the above unevenness can only be alleviated by continuously increasing the ventilation pipes, but it cannot be completely avoided. However, too many pipes will significantly affect the feeding and unloading speed, the storage flow pattern and stress distribution, and ultimately change the stress form of the silo body, seriously threatening the safety of the silo body.

[0006] Conical hopper ventilation, i.e. setting ventilation holes in the conical hopper part at the bottom of the silo to further increase the ventilation efficiency. However, this method also has some defects in the actual design process. First, in the current design of concrete silos, most of them use steel conical hoppers to avoid the defects of concrete conical hoppers such as slow construction speed, long construction period, poor wear resistance, and difficulty in replacement; second, the upper part of the conical hopper bears the vertical load such as the pressure of the entire storage, the mass of the silo top and the self-weight of the silo top equipment, etc., and the stress of the conical hopper discharge port decreases suddenly to zero. Considering that the height of the conical hopper is relatively small, the stress of the conical hopper is abnormally complex and large in value. However, the setting of ventilation ducts at the conical hopper will inevitably cause local stress concentration, seriously affecting the safety of the conical hopper, and it is extremely likely that the conical hopper will be torn.

[0007] At present, there is no effective ventilation method for spiral flanging steel plate silos for storing crops such as grain. The main function of the existing ventilation holes and dust collectors in the silo top is not ventilation, but to maintain pressure balance in the silo to prevent negative pressure and silo collapse in extreme cases and to collect dust to prevent explosion. Therefore, how to overcome the above technical problems and defects has become a problem that needs to be solved. SUMMARY

[0008] The purpose of the present application is to overcome the defects described in the background art, thereby realizing a multi-mode adjusted constant temperature and humidity silo. Based on the special structure and stress characteristics of the spiral flanging steel plate silo, the silo structure is innovatively improved under the premise of ensuring the safety and stability of the silo structure. Not only is the constant temperature and humidity control digitized and efficient, but also the feeding method of the silo body is improved, effectively improving the structural stability of the spiral flanging steel plate silo during use, and significantly reducing the incidence of silo collapse and silo collapse (silo collapse) and other engineering accidents.

[0009] The technical scheme of the application is as follows: a multi-mode adjusted constant temperature and humidity silo, comprising a silo body, an inner cylinder, an inner cylinder water cooling assembly, a bottom air cooling assembly and a monitoring and control assembly, wherein the silo body is a spiral edge steel plate silo vertically fixed by a support, a feeding port is arranged at the center of the top cone of the silo body, and at least one silo top ventilation hole is arranged at the top periphery of the silo body; the inner cylinder is concentrically fixed in the inner cavity of the silo body, a material distribution part is arranged at the top end of the inner cylinder, and the material distribution part is located directly below the feeding port; the inner cylinder water cooling assembly is arranged on the inner side wall of the inner cylinder to perform water cooling on the periphery of the inner cylinder; the bottom air cooling assembly is fixedly arranged at the bottom end of the inner cylinder in the silo body, cooling air is introduced into the inner cylinder, and the cooling air enters the inner cavity of the silo body from the air outlet hole arranged at the top of the inner cylinder and is finally discharged from the silo top ventilation hole; and the monitoring and control assembly monitors the temperature and humidity of the outer wall of the inner cylinder and the silo body in real time and controls the coordinated work of the inner cylinder water cooling assembly and the bottom air cooling assembly.

[0010] In the multi-mode adjusted constant temperature and humidity silo, a silo wall water cooling assembly is further arranged on the spiral edge of the outer side of the silo body to perform water cooling on the outer wall of the silo body, and the work of the silo wall water cooling assembly is coordinated and controlled by the monitoring and control assembly.

[0011] In the multi-mode adjusted constant temperature and humidity silo, a thermal insulation layer is wrapped on the silo body at the periphery of the silo wall water cooling assembly. The thermal insulation layer effectively prevents the heat transfer between the external heat of the silo and the stored material while reducing the temperature of the stored material.

[0012] In the multi-mode adjusted constant temperature and humidity silo, the bottom air cooling assembly comprises a plurality of metal support pipes fixedly arranged in a staggered manner and a blower, the intersection points of the metal support pipes are located on the inner side of the inner cylinder, the top of the inner side part of the metal support pipes is open or provided with air inlet holes, so that the cooling air can enter the inner cavity of the inner cylinder, the outer ends of the metal support pipes extend to the outside of the silo body and are connected with the blower, and the work of the blower is controlled by the monitoring and control assembly.

[0013] In the multi-mode adjusted constant temperature and humidity silo, the metal support pipe comprises a pipe bottom part with an open rectangular cross section and a pipe top part with an arc-shaped cross section, the pipe top part is fixedly arranged on the top of the pipe bottom part, and the inner side part of the metal support pipe is not provided with the pipe top part or is provided with a plurality of air inlet holes on the pipe top part.

[0014] In the multi-mode regulated constant temperature and humidity silo, the wall water cooling assembly and the inner cylinder water cooling assembly each comprise a water cooling pipe and a circulating water pump, the circulating water pumps of the two can be independently arranged or shared.

[0015] In the multi-mode regulated constant temperature and humidity silo, the material distributing part is a rotatable material distributing cone for distributing material, the material distributing cone comprises a cone body and a material pushing piece fixed on the cone face of the cone body, and the material pushing piece is arranged in an inclined or arc shape so as to rotate by itself when material is fed. The main function of the material pushing piece is to distribute the fed material, so that the storage material is more uniformly distributed, and the problems of arching, concentration of impurities and uneven distribution of particles during unloading are avoided.

[0016] In the multi-mode regulated constant temperature and humidity silo, the monitoring and control assembly comprises a temperature and humidity sensor and a controller, the temperature and humidity sensor is arranged on the inner side wall of the inner cylinder and the inner side wall of the silo body, and feeds back the real-time monitored temperature and humidity data to the controller. After the temperature and humidity data are collected, the controller automatically determines whether to open the corresponding air cooling (silo bottom air cooling assembly) and water cooling (silo wall water cooling assembly and inner cylinder water cooling assembly), and can intelligently control the air volume and flow rate. The controller collects the temperature and humidity data through the temperature and humidity sensor, and then automatically controls the coordinated operation of the air blower and the circulating water pump, and adjusts the power to control the air volume and the flow rate of the cooling water. This is a mature automatic control technology, and the control principle is not the innovation point of the present application, so it will not be described again.

[0017] The multi-mode regulated constant temperature and humidity silo has the following advantages: 1. The multi-mode regulated constant temperature and humidity silo combines the special structure and stress characteristics of the spiral flanging steel plate silo, and innovatively improves the silo structure and heat dissipation form under the premise of ensuring the safety and stability of the silo structure. The mixed cooling mode of "water cooling + air cooling" and "silo wall + silo inner" not only significantly improves the cooling and dehumidification efficiency, but also makes the temperature and humidity distribution of the stored material in the silo more uniform. The adoption of the above measures effectively improves the disadvantages of the existing concrete silo, such as large temperature difference between the upper and lower stored materials, slow cooling speed, and the like, and realizes the intelligent and efficient constant temperature and humidity storage cooling control of the spiral flanging steel plate silo by means of the automatic monitoring and control assembly.

[0018] 2. The multi-mode adjustable constant temperature and humidity silo of this invention features significant structural optimization. It employs a unique "silo-within-a-silo" design, improving the silo's feeding method. Combined with internal air-cooling within the "silo-within-a-silo," this effectively enhances the structural stability of the spiral-rolled steel silo during use, ensuring adequate internal pressure during feeding and unloading. The top ventilation holes significantly reduce the probability of silo collapse and tipping during feeding and discharging, ensuring storage safety. Furthermore, the "silo-within-a-silo" structure does not alter the structural stress distribution or construction method of the spiral-rolled steel silo, resulting in a safe, stable, and easy-to-construct silo structure.

[0019] 3. The multi-mode adjustable constant temperature and humidity silo of the present invention adopts a cooling method of air cooling (bottom air cooling component) + water cooling (wall water cooling component and inner cylinder water cooling component), which avoids the defects of low efficiency and high resistance of traditional air duct ventilation method, and effectively avoids the generation of condensation in the inner cylinder, significantly improving the cooling efficiency. The cooling efficiency of the constant temperature silo of the present invention is conservatively estimated to be 3 to 5 times higher than that of traditional silo ventilation method, achieving efficient storage cooling.

[0020] 4. The multi-mode adjustable constant temperature and humidity silo of the present invention contains stored material in the conical hopper below the inner cylinder. Due to the height of the silo, an upward airflow is generated under the "chimney effect," which is consistent with the airflow introduced by the blower, improving the airflow of the stored material inside the silo and further reducing the temperature and humidity of the stored material. The inner cylinder air-cooling method of the present invention differs from the traditional air-cooling method, as it does not directly blow air onto the stored material, effectively avoiding the defects of excessively dry surface of the stored material and high internal humidity, thus significantly improving the quality of the stored material.

[0021] 5. The multi-mode adjustable constant temperature and humidity silo of the present invention is equipped with an inner cylinder, but the inner cylinder is empty of stored material, which completely changes the storage method. Combined with the use of a rotatable distribution cone, the stored material is dispersed during feeding, fundamentally changing the flow pattern of the stored material during unloading. This prevents arching under the action of the natural angle of repose, eliminating the need for components such as air cannons, thus saving investment. It also changes the flow state of the stored material during discharge. Combined with the flow-blocking effect of the metal support pipe at the bottom of the inner cylinder, the unloading speed is effectively controlled, preventing silo overflow accidents during unloading.

Detailed Implementation

[0024] The multi-mode adjustable constant temperature and humidity silo of the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0025] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] This embodiment features a multi-mode adjustable temperature and humidity silo. Based on the structural form and stress characteristics of a spiral-rolled steel silo, this silo incorporates several innovative improvements to its structure while ensuring structural safety and stability. These improvements not only achieve intelligent and efficient temperature and humidity control but also enhance the material feeding method, effectively improving the structural stability of the spiral-rolled steel silo during use and significantly reducing the incidence of engineering accidents such as silo collapse and tipping. Specifically, see [link to documentation]. Figure 1 and Figure 2 The silo comprises a silo body 1, an inner cylinder 2, an inner cylinder water-cooling assembly 3, a bottom air-cooling assembly 4, and a monitoring and control assembly. The silo body is a spiral-rolled steel plate silo with a conical top 101 at its upper part. A guardrail 106 is typically fixed around the perimeter of the conical top to ensure the safety of workers. A conical hopper 102 is located at the bottom of the silo body, with a discharge port 105 at the bottom of the hopper. The silo body is vertically fixed by a support structure; in this embodiment, the support structure is a steel frame 6. A feed inlet 103 is located at the center of the conical top of the silo body, and at least one ventilation hole 104 is located around the top perimeter. In this embodiment, four ventilation holes are provided, evenly distributed around the circumference of the conical top.

[0027] In this embodiment, as one of the core inventive points of the present invention, the inner cylinder 2 is concentrically fixed within the inner cavity of the silo body 1. To increase the stability of the inner cylinder, several supporting steel pipes 203 can be inclinedly welded to the lower periphery of the inner cylinder. See [link to relevant documentation]. Figure 2 and Figure 5 The inner cylinder 2 has a material distribution section at its top, located directly below the feed inlet 103. In this embodiment, see... Figure 2 , Figure 8 and Figure 9 The material distribution section is a rotatable material distribution cone 201 for dispersing materials. The material distribution cone includes a cone body 211 and a material-pushing plate 212 fixed to its cone surface. The material-pushing plate 212 is inclined or arc-shaped, allowing it to rotate during material feeding. The material-pushing plate 212 is welded from a 20mm thick steel plate, primarily to facilitate the formation of a discharge channel. The upper part of the partition plate is a cone welded from a steel plate, its main function being to strengthen the rigidity of the material distribution cone and prevent material accumulation at the top. The rotating material distribution cone primarily disperses the material feed, resulting in a more uniform material distribution and preventing phenomena such as arching during discharge, concentration of impurities, and uneven particle distribution.

[0028] To increase the strength of the silo body and inner cylinder, stiffening ribs 107 are welded and fixedly installed circumferentially on the inner sidewalls of both the silo body 1 and the inner cylinder 2. Ring beams 109 are welded and fixedly installed at the upper and lower ends of the stiffening ribs inside both the silo body 1 and the inner cylinder 2. Their main function is to constrain the deformation of the stiffening ribs 107 and bear the forces transmitted by the stiffening ribs 107. (See also...) Figure 3 and Figure 5In practical applications, the stiffening ribs can be made of channel steel and vertically welded and fixed.

[0029] To achieve cooling around the inner cylinder, see [link / reference]. Figure 2 and Figure 3 The inner cylinder water-cooling assembly 3 is distributed throughout the inner wall of the inner cylinder 2 to provide water cooling for the area surrounding the inner cylinder. It also includes a silo wall water-cooling assembly 7, which is coiled on the spiral edge 108 on the outer side of the silo body and uses a non-welded connection method. See [link to documentation]. Figure 6 The outer wall of the silo is cooled by water cooling, and an insulation layer 8 covers the silo body surrounding the water-cooled silo wall assembly 7. The insulation layer 8 effectively isolates external heat from the stored material while reducing its temperature and humidity. The operation of the water-cooled silo wall assembly is coordinated and controlled by the monitoring and control assembly.

[0030] In this embodiment, both the silo wall water-cooling assembly 7 and the inner cylinder water-cooling assembly 3 include water-cooling pipes 301 and circulating water pumps. The circulating water pumps for both can be independently installed or shared. The water-cooling pipes 301 are introduced from the bottom outer wall of the silo body 1 into the inner cylinder 2 and are evenly distributed on the inner side wall of the inner cylinder. The distribution of the water-cooling pipes 301 on the inner side of the inner cylinder 2 can be a vertically serpentine even distribution, see [reference needed]. Figure 2 and Figure 3 Alternatively, a spiral distribution can be used (not shown in the attached diagram). The arrangement of the water-cooling pipes 301 can be flexible and varied. Other arrangements of water-cooling pipes that achieve the same function should be considered as not exceeding the protection scope of this invention. The circulating water pump provides power for the circulation of cooling water within the water-cooling pipes, and the operation of the circulating water pump is centrally controlled by the monitoring and control components.

[0031] With the inner cylinder water-cooled as a prerequisite, multi-mode coordinated cooling is achieved in conjunction with the bottom air-cooling component 4. Specifically, see [link to documentation]. Figure 2 and Figure 3 The bottom air-cooling assembly 4 is fixedly installed inside the silo body 1 at the bottom end of the inner cylinder 2. It introduces cooling air into the inner cylinder and enters the inner cavity of the silo body through the air outlet 202 provided at the top of the inner cylinder, and finally discharges it through the ventilation hole at the top of the silo. The bottom air-cooling assembly 4 includes multiple interlaced and fixedly arranged metal support pipes 401 and a blower. The intersection point of the metal support pipes 401 is located inside the inner cylinder 2, and the top of the metal support pipes 401 located inside the inner cylinder 2 is open or has air outlet holes, so that cooling air can enter the inner cavity of the inner cylinder 2. The outer end of the metal support pipe 401 extends to the outside of the silo body 1 and is connected to the blower. The operation of the blower is centrally controlled by the monitoring and control assembly.

[0032] In this embodiment, see Figure 7As shown in Figure B, the metal support pipe 401 includes a bottom pipe 411 with an open rectangular cross-section and a top pipe 412 with an arc-shaped cross-section. The top pipe 412 is sealed and welded to the top of the bottom pipe 411, forming a hollow pipe, which also provides support for the inner cylinder. The portion of the metal support pipe located inside the inner cylinder 2 may not have a top pipe 412, or the top pipe may have multiple air outlets. See [reference needed]. Figure 7 As shown in Figure C, the air from the external blower is poured into the inner cylinder through the pipe, enters the inner cylinder through the open part without the top of the pipe or the air outlet, and forms an upward airflow. It then enters the inner cavity of the silo through the air outlet 202 set at the top of the inner cylinder 2, and finally exits from the silo top ventilation hole 103.

[0033] The metal support tube 401 adopts an arc-shaped capped top 412, see [reference]. Figure 7 The main reason is that the material stored in the upper part cannot accumulate, resulting in less resistance during unloading and ensuring that there is no material stored on the support, thus preventing mold growth.

[0034] The monitoring and control component monitors the temperature and humidity of the inner cylinder 2 and the inner wall of the silo 1 in real time, and controls the coordinated operation of the inner cylinder water-cooling component and the bottom air-cooling component. In this embodiment, the monitoring and control component includes a temperature and humidity sensor and a controller, see [link to documentation]. Figure 3 The temperature and humidity sensor 5 is installed on the inner wall of the inner cylinder 2 and the inner wall of the silo body 1, feeding back the real-time monitored temperature and humidity data to the controller. After the temperature and humidity data is collected, the controller automatically determines whether to turn on the corresponding air cooling (bottom air cooling component) and water cooling (wall water cooling component and inner cylinder water cooling component). Correspondingly, the start and stop of the blower and circulating water pump are centrally and automatically controlled by the controller. At the same time, the air volume and cooling water flow can be intelligently adjusted by controlling the speed of the blower and circulating water pump. The controller collects temperature and humidity data through the temperature and humidity sensor 5, and then automatically controls the coordinated operation of the blower and circulating water pump, and realizes the power adjustment to regulate the air volume and cooling water flow. This is a mature automatic control technology, and its control principle is not the innovation of this invention, so it will not be described again.

[0035] The working principle of the multi-mode adjustable constant temperature and humidity silo of the present invention: When the silo body 1 is fed, the stored material enters from the feed port 103 at the top of the cone of the silo body and falls onto the distribution cone 201 that is rotated at the top of the inner cylinder 2. The distribution cone continues to rotate, evenly distributing the stored material in the silo body 1 around the inner cylinder 2 until the silo body is filled with a predetermined amount of stored material.

[0036] After the material is fed in, it is stored in the silo 1. When the temperature and humidity sensors 5 on the inner wall of the inner cylinder 2 and the inner wall of the silo detect abnormal temperature and humidity, the signal is fed back to the controller. The controller then controls the blowers and circulating water pumps of the air-cooled (bottom air-cooled components) and water-cooled (wall water-cooled components and inner cylinder water-cooled components) systems to start working together to cool down the silo until the temperature and humidity reach the range preset by the controller. The cylinder-within-a-cylinder structure and the internal air-cooling system ensure the pressure inside the silo during feeding and unloading. Combined with the ventilation holes on the top of the silo, it can prevent negative pressure collapse accidents that may occur during feeding and unloading. The "water-cooling + air-cooling" cooling method avoids the shortcomings of low efficiency and high resistance of traditional air duct ventilation methods, and effectively prevents condensation in the inner cylinder, significantly improving the cooling efficiency. It is conservatively predicted that its cooling efficiency is 3 to 5 times higher than that of traditional methods, achieving efficient temperature and humidity control in storage.
