Specific embodiments

[0032] The following will make a detailed description of the two embodiments of the present application with reference to the accompanying drawings.

[0033] The first embodiment

[0034] Figures 1 - 9 It shows that it includes a raw grain storage body 1, a control panel 12 fixedly installed at the front end of the raw grain storage body 1, and an automatic adjustment processing unit carried in the control panel 12. A plurality of support bars are fixedly connected to the front and rear inner walls of the raw grain storage body 1. The inner ends of the support bars are fixedly connected with a heat insulation layer 5, and a heat insulation gap is formed between the raw grain storage body 1 and the heat insulation layer 5;

[0035] The input end of the automatic adjustment processing unit is connected to a temperature and humidity sensing unit, a temperature difference sensing unit, and a grain parameter sensing unit, and the output end of the automatic adjustment processing unit is connected to a ventilation temperature control adjustment unit and a heat insulation adjustment unit;

[0036] A plurality of internal temperature sensing components 4 are installed in the middle of the outer end of the raw grain storage body 1, and the inner ends of the internal temperature sensing components 4 extend through the heat insulation gap to the inner side of the heat insulation layer 5, and a temperature difference sensing component 7 is also arranged inside the internal temperature sensing components 4;

[0037] The input end of the temperature and humidity sensing unit is signal-connected to the internal temperature sensing component 4, the input end of the temperature difference sensing unit is signal-connected to the temperature difference sensing component 7, the input end of the grain parameter sensing unit is signal-connected to the input end on the control panel 12, and the output ends of the ventilation temperature control adjustment unit and the heat insulation adjustment unit are both signal-connected to the ventilation fan group arranged at the rear side of the raw grain storage body 1. Through the cooperation of the internal temperature sensing component 4, the heat insulation layer 5, the temperature difference sensing component 7 and each unit, on the one hand, it can play an isolation role between the inside and outside of the raw grain storage body 1, effectively avoiding the direct action of the external temperature on the inside of the raw grain storage body 1, avoiding the influence of the condensation on the inner wall of the raw grain storage body 1 on the grain in the bin, effectively reducing the problem of condensation of the grain in the bin due to temperature difference, and on the other hand, it can also control the temperature in the heat insulation gap formed between the raw grain storage body 1 and the heat insulation layer 5, further reducing the influence caused by the change of the external temperature on the inside of the raw grain storage body 1, playing an effective role in heat preservation and isolation. While fully ensuring the storage temperature inside the raw grain storage body 1, it also reduces its influence rate by the change of the external temperature, thereby effectively ensuring the storage quality of the raw grain storage body 1, avoiding the problem of mildew of the grain in the bin, and prolonging the storage time of the grain and ensuring the quality of the grain.

[0038] Figures 3 - 8 It is shown that the internal temperature sensing component 4 includes an outer layer embedding block 41 embedded in the raw grain storage body 1 and a temperature sensing embedding block 42 embedded in 5, and the outer layer embedding block 41 and the temperature sensing embedding block 42 are arranged in correspondence. A temperature and humidity sensing probe 421 extending into the heat insulation layer 5 is fixedly connected to the inner end of the temperature sensing embedding block 42. The input end of the temperature difference sensing unit is signal-connected to the temperature and humidity sensing probe 421. The setting of the temperature and humidity sensing probe 421 can monitor the temperature and humidity data of the grain in the raw grain storage body 1 in real time, and then can effectively assist the automatic adjustment processing unit to control the ventilation temperature control adjustment unit, ensure the temperature and humidity inside the raw grain storage body 1, so as to ensure the storage quality and storage period of the grain, and can also respond and process in time when the temperature and humidity data in the bin are abnormal, improving the automation degree and emergency response efficiency of the raw grain storage body 1.

[0039] Figures 3 - 8It is shown that the temperature difference induction component 7 includes a pressure insert block 75 embedded at the outer end of the temperature sensing insert block 42. A sliding channel 411 is formed in the outer layer insert block 41. An I-shaped connecting block 72 is slidably connected in the sliding channel 411. A temperature guiding sealing block 412 extending to the outside of the raw grain storage body 1 is fixedly connected to the outer end of the outer layer insert block 41. A temperature sensing deformation strip 71 is fixedly connected between the temperature guiding sealing block 412 and the I-shaped connecting block 72;

[0040] The inner end of the outer layer insert block 41 is fixedly connected with a heat insulation elastic sleeve 73 communicating with the sliding channel 411. The inner end of the I-shaped connecting block 72 is fixedly connected with the heat insulation elastic sleeve 73. A pressure package 74 is fixedly connected to the inner end of the heat insulation elastic sleeve 73. The inner end of the pressure package 74 is fixedly connected with the pressure insert block 75, and the pressure package 74 is communicated with the pressure insert block 75. A pressure probe 76 is fixedly connected in the pressure insert block 75. The input end of the temperature difference induction unit is signal-connected to the pressure probe 76. The cooperation of the temperature sensing deformation strip 71, the I-shaped connecting block 72, the heat insulation elastic sleeve 73, the pressure package 74 and the pressure probe 76 can not only sense the external environmental temperature, but also directly generate corresponding deformations through the change of the external temperature, so that the automatic adjustment processing unit can directly obtain the data generated by the temperature difference. While improving the temperature difference induction efficiency and processing, it can also reduce the difficulty of data calculation and processing of the automatic adjustment processing unit, thereby reducing the burden and construction cost of the system operation, and effectively promoting the economic benefits of the application of the raw grain storage body 1.

[0041] Figures 3 - 8 It is shown that the temperature sensing deformation strip 71 is made of a multi-segment temperature-changing memory metal wire composite. When the temperature sensing deformation strip 71 does not generate deformation, the pressure package 74 is in a semi-contracted state, and the stiffness coefficient of the heat insulation elastic sleeve 73 is greater than that of the pressure package 74, which can maintain semi-compression of the pressure package 74. The temperature inside the warehouse of the raw grain storage body 1 is controlled at 15°C - 25°C, which can effectively store grains such as wheat, corn, and rice. Then, the state of the temperature sensing deformation strip 71 at 15°C - 25°C is selected as the normal state. It generates a contraction deformation when the sensed temperature is lower than 12°C, and generates an elongation deformation when the sensed temperature is higher than 28°C. Furthermore, it can generate a deformation-triggered reaction in a timely manner when the external temperature changes, so that the automatic adjustment processing unit can timely control the temperature of the heat insulation gap formed between the raw grain storage body 1 and the heat insulation layer 5, avoiding the influence of the external temperature on the temperature of the grains in the warehouse of the raw grain storage body 1, effectively avoiding the probability of grain condensation while effectively ensuring the stability of the temperature inside the warehouse of the raw grain storage body 1.

[0042] Figure 1 and Figure 9It is shown that a feed hopper 11 fixedly connected to the upper end of the raw grain storage body 1 is in communication with the heat insulation layer 5. A heat insulation air inlet 2 is fixedly installed on the left side of the feed hopper 11 at the upper end of the raw grain storage body 1, and a heat insulation circulation port 21 is fixedly installed on the right side of the feed hopper 11. Both the heat insulation air inlet 2 and the heat insulation circulation port 21 are in communication with the heat insulation gap. The other ends of the heat insulation air inlet 2 and the heat insulation circulation port 21 are connected to the ventilation fan group through an extension pipe. The settings of the heat insulation air inlet 2 and the heat insulation circulation port 21 can effectively control the temperature circulation of the heat insulation gap formed between the raw grain storage body 1 and the heat insulation layer 5. By introducing transitional circulating air into the heat insulation gap, effective heat insulation is achieved, playing an effective role in heat exchange and temperature control, effectively avoiding the influence of external temperature changes on the temperature inside the raw grain storage body 1, avoiding the problem of grain condensation, and thus improving the storage quality of the raw grain storage body 1. Moreover, the inner wall temperature of the raw grain storage body 1 can be maintained through the heat insulation circulation method, reducing the problem of condensation on it, and further ensuring the storage quality of the raw grain storage body 1.

[0043] Figure 2 and Figure 9 It is shown that the output end of the automatic adjustment processing unit is also connected to a ventilation temperature control unit. An electric heating sleeve and a temperature measuring probe are also sleeved outside the heat insulation air inlet 2. The output end of the ventilation temperature control unit is signal-connected to the electric heating sleeve, and the input end of the ventilation temperature control unit is also signal-connected to the temperature measuring probe. The settings of the ventilation temperature control unit, the electric heating sleeve, and the temperature measuring probe can, when the external temperature is relatively low, deliver air with a relatively high temperature to the heat insulation gap. The maximum value of this relatively high temperature cannot exceed the upper limit temperature of 25 °C for grain storage, and can effectively achieve the function of maintaining the temperature inside the warehouse.

[0044] Figure 1 and Figure 9 It is shown that a ventilation temperature control air inlet 3 fixedly connected to the upper left side of the raw grain storage body 1 is in communication with the heat insulation layer 5. A plurality of ventilation circulation ports 31 fixedly connected to the middle and lower right side of the raw grain storage body 1 are in communication with the heat insulation layer 5, and the plurality of ventilation circulation ports 31 are evenly distributed in the vertical direction. The input end of the ventilation temperature control air inlet 3 is connected to the ventilation fan group, and the output end of the ventilation circulation port 31 is connected to the ventilation fan group. Moreover, the plurality of ventilation circulation ports 31 are independently controlled. The settings of the plurality of ventilation circulation ports 31 can promote the effect and uniformity of regulating the temperature inside the raw grain storage body 1, thereby increasing the ventilation volume and ventilation efficiency inside the grain, effectively avoiding the problem of poor heat dissipation inside the grain, and thus effectively ensuring the storage quality of the grain.

[0045] It should be noted that the ventilation fan group is a prior art and may include a blower group, an air dryer, an air filter, a plurality of connecting pipes, and control valves respectively installed on the connecting pipes. The input end of the blower group is connected to the air dryer and the air filter. The output end of the blower group is respectively connected to the extension pipe on the heat insulation air outlet 2 and the ventilation temperature control air outlet 3 through the connecting pipes. Moreover, the extension pipe on the heat insulation circulation port 21 and the ventilation circulation port 31 are both connected to the air dryer or the air filter through the connecting pipes, thereby forming a circulation control of ventilation and being able to regulate the circulation efficiency. Here, the ventilation fan group is only for reference, and those skilled in the art can select and add the specific setting method according to actual needs. Set the ventilation fan parameters: When the volume of the raw grain storage body 1 is set to 40 m³, the output wheat capacity does not exceed 30 T, the stored rice throughput does not exceed 23 T. And when storing wheat in the raw grain storage body 1, the air volume of the blower group is selected to be 5000 m³ / h - 9000 m³ / h, the air pressure of the blower group is 1350 Pa - 2890 Pa, and the power of the blower group is 11 kw; when storing rice in the raw grain storage body 1, the air volume of the blower group is selected to be 4000 m³ / h - 7000 m³ / h, the air pressure of the blower group is 1050 Pa - 2200 Pa, and the power of the blower group is 11 kw; when storing corn in the raw grain storage body 1, the air volume of the blower group is selected to be 4800 m³ / h - 8500 m³ / h, the air pressure of the blower group is 750 Pa - 1550 Pa, and the power of the blower group is 11 kw. The relevant parameters can be adjusted according to the actual usage conditions.

[0046] Figures 1 - 9 It is shown that after storing grains in the raw grain storage body 1, relevant technical personnel set the internal storage parameters of the raw grain storage body 1 according to the variety of grains and the local environment requirements. Through the input end of the control panel 12, parameters such as the variety of stored grains, storage temperature, storage humidity, and temperature and humidity fluctuation standards are input into the grain parameter sensing unit, and then the grain parameter sensing unit transmits these parameters to the automatic adjustment processing unit;

[0047] When the grains are just put into the warehouse, the automatic adjustment processing unit can judge the basic temperature and humidity of the grains through the grain temperature and humidity data transmitted by the temperature and humidity sensing probe 421 to the temperature and humidity sensing unit, and then send a ventilation and temperature control command to the ventilation and temperature control adjustment unit to pre-dehumidify and cool the grains. Then, after the grain temperature and humidity reach the standard and are stable, the automatic adjustment processing unit controls the ventilation and temperature control adjustment unit to enter the energy-saving ventilation and temperature control mode, which can solve the energy consumption while ensuring the grain storage environment and improve the environmental protection of the raw grain storage body 1;

[0048] In the subsequent continuous use of the raw grain storage body 1, if the external temperature is within the standard range of the grain storage temperature, the temperature-sensitive deformation strip 71 will not be deformed, and the pressure probe 76 transmits the balanced temperature data to the temperature difference sensing unit, so that the automatic adjustment processing unit can directly judge the external temperature data. At the same time, the temperature and humidity sensing probe 421 transmits the temperature and humidity data of the grain to the automatic adjustment unit through the temperature and humidity sensing unit, and the automatic adjustment processing unit sends an energy-saving temperature control instruction to the ventilation and temperature control unit, so as to achieve good temperature control and energy-saving and environmental protection effects;

[0049] If the outside temperature is lower than the standard range of the grain storage temperature and reaches the low-temperature deformation temperature of the temperature-sensitive deformation strip 71, the temperature-sensitive deformation strip 71 will contract, thereby driving the I-shaped connecting block 72 to move toward the outside of the raw grain storage body 1 in the sliding channel 411, and the contraction of the temperature-insulating elastic sleeve 73 drives the pressure bag 74 to stretch and deform, thereby releasing the space of the pressure bag 74, reducing its internal pressure, and making the pressure probe 76 sense the pressure reduction. Then, the pressure probe 76 transmits the data of the pressure reduction to the temperature difference sensing unit, and the temperature difference sensing unit feeds back the data of the low temperature outside. To the automatic adjustment processing unit, after receiving the low-temperature temperature difference data, the automatic adjustment processing unit sends a control instruction to the insulation adjustment unit, and sends an instruction to the ventilation temperature control unit, using the electric heating sleeve to heat the air in the insulation air outlet 2, and sends temperature data to the ventilation temperature control unit through the temperature sensing of the temperature measuring probe, so as to avoid the influence of the insulation temperature on the grain temperature caused by the excessively high insulation temperature, and also avoid the problem of condensation on the grain. The insulation adjustment unit starts the pipe valve of the ventilation fan unit to supply air to the insulation air outlet 2, so that air with a certain amount of heat enters the original The heat is discharged from the insulation gap between the grain storage body 1 and the insulation layer 5 through the insulation circulation port 21. The insulation circulation method is used to prevent the external low temperature from being transmitted to the warehouse of the raw grain storage body 1, and reduce the problem of condensation on the inner wall of the raw grain storage body 1. Then, due to the insulation circulation effect of the insulation gap, the raw grain storage body 1 will have a certain temperature increase effect, so that the environment near the outside of the raw grain storage body 1 has a certain temperature increase effect. At the same time, it will act on the temperature-sensitive deformation strip 71 through the heat-conducting sealing block 412, and the automatic adjustment processing unit will continuously adjust the data of the temperature difference sensing unit. The temperature state caused by the external temperature is judged by reading continuously, and when the temperature-sensing deformation strip 71 keeps shrinking continuously, it is judged that the external temperature is low at this time, and the temperature caused is high, and then the temperature-insulating adjustment unit continuously produces the temperature-insulating circulation effect. After the temperature-sensing deformation strip 71 produces the recovery deformation, the automatic adjustment processing unit judges that the temperature difference between the external temperature and the temperature in the warehouse is small at this time, and sends a periodic action instruction to the temperature-insulating adjustment unit and the ventilation temperature control unit, so as to ensure the temperature-insulating effect while saving energy, thereby improving the storage quality of the raw grain storage body 1 and reducing the pathological effect of the grain;

[0050] If the external temperature is higher than the standard range of the grain temperature and reaches the high-temperature deformation temperature of the temperature-sensitive deformation strip 71, the temperature-sensitive deformation strip 71 produces an elongation effect, which in turn drives the I-shaped connecting block 72 to move towards the inside of the raw grain storage body 1 in the sliding channel 411. The elongation of the heat-insulating elastic sleeve 73 drives the pressure package 74 to produce a compressive deformation, thereby reducing the space of the pressure package 74 and increasing its internal pressure, so that the pressure probe 76 senses an increase in pressure. Then, the pressure probe 76 transmits the data of the increased pressure to the temperature difference sensing unit, and the temperature difference sensing unit feeds back the data of the external high temperature to the automatic adjustment processing unit. After receiving the high-temperature difference data, the automatic adjustment processing unit sends a control command to the heat-insulating adjustment unit, and the heat-insulating adjustment unit activates the pipeline valve of the ventilation fan group to send air into the heat-insulating gap between the raw grain storage body 1 and the heat-insulating layer 5, and then discharges it through the heat-insulating circulation port 21. By means of heat-insulating circulation, it is possible to prevent the transmission of external high temperature into the warehouse of the raw grain storage body 1 and reduce the problem of condensation on the inner wall of the raw grain storage body 1 and the grain. Then, due to the heat-insulating circulation effect of the heat-insulating gap, the raw grain storage body 1 will have a certain cooling effect, making the environment near the outside of the raw grain storage body 1 have a certain cooling effect. At the same time, it will act on the temperature-sensitive deformation strip 71 through the heat-conducting sealing block 412. The automatic adjustment processing unit continuously reads the data of the temperature difference sensing unit to judge the temperature state caused by the external temperature. When the temperature-sensitive deformation strip 71 maintains continuous elongation, it is judged that the external temperature is relatively high at this time, resulting in a relatively large temperature, and then continuously and continuously generates a heat-insulating circulation effect on the heat-insulating adjustment unit. And the automatic adjustment processing unit sends an instruction to enhance ventilation to the ventilation temperature control adjustment unit to reduce the influence of external high temperature on the grain temperature and ensure the stability of the grain storage environment, thereby improving the storage quality of the grain. After the temperature-sensitive deformation strip 71 produces a recovery deformation, the automatic adjustment processing unit judges that the temperature difference between the external temperature and the temperature in the warehouse is relatively small at this time, and sends an instruction for periodic action to the heat-insulating adjustment unit, which can save energy while ensuring the heat-insulating effect, thereby improving the storage quality of the raw grain storage body 1 and reducing the pathological effect of the grain.

[0051] The second implementation mode

[0052] Figures 1 - 9It is shown that the input end of the automatic adjustment processing unit is also connected with a gap humidity sensing unit. A liquid outlet 6 communicating with the heat insulation gap is fixedly connected to the lower end of the original grain storage body 1. A humidity measuring probe is arranged in the liquid outlet 6. The input end of the gap humidity sensing unit is signal-connected to the humidity measuring probe. The gap humidity sensing unit and the humidity measuring probe can effectively detect the humidity data in the heat insulation gap, that is, assist the automatic adjustment processing unit to judge the condensation condition on the inner wall of the original grain storage body 1, so that it can effectively control the ventilation temperature of the heat insulation adjustment unit. While ensuring the heat insulation circulation effect, the problem of condensation on the inner wall of the original grain storage body 1 is effectively reduced, thereby further ensuring the storage effect of the original grain storage body 1.

[0053] Figure 2 and Figure 9 It is shown that the output end of the automatic adjustment processing unit is also connected with an alarm unit and a remote transmission unit. The output end of the alarm unit is signal-connected to an alarm arranged on the upper end of the control panel 12. The output end of the remote transmission unit is signal-connected to a wireless signal transmitter arranged in the control panel 12. The alarm unit and the remote transmission unit can promote the monitoring and adjustment of the original grain storage body 1, reduce the maintenance difficulty of technicians, improve the maintenance efficiency, and promote the efficiency of the emergency response.

[0054] Figures 1 - 9 It is shown that during the process of the automatic adjustment processing unit ventilating and controlling the temperature of the inner bin of the original grain storage body 1 and regulating the heat insulation of the heat insulation gap, the test probe in the liquid outlet 6 will transmit the data in the heat insulation gap to the gap humidity sensing unit, and then transmit it to the automatic adjustment processing unit after conversion, so that the automatic adjustment processing unit can timely discover the problem of condensation on the inner wall of the original grain storage body 1, and issue control instructions to the heat insulation adjustment unit and the ventilation temperature control unit according to the humidity data of the heat insulation gap, and promote the dissipation of the humidity on the inner wall of the original grain storage body 1 through the heat insulation cycle, so as to ensure the dryness of the original grain storage body 1. If the humidity data transmitted by the gap temperature sensing unit to the automatic adjustment processing unit still continues to increase during the continuous action process, the automatic adjustment processing unit will send signals to the alarm unit and the remote transmission unit, so that the alarm unit activates the alarm to send an audible and visual alarm signal to relevant technicians, and then transmits data to the mobile terminal through the wireless signal transmitter, so as to improve the emergency efficiency, timely inspect and maintain the original grain storage body 1, and reduce the failure loss rate.

[0055] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
