Description

Technical Field

[0001] The utility model belongs to the technical field of material storage, in particular to a steel silo thermal insulation structure. Background Art

[0002] Steel silos are storage facilities built with steel plates. They usually have a sturdy structure and waterproof properties, which can effectively protect the stored items from the external environment. They usually have a long service life and are easy to maintain. In order to reduce the impact of the external temperature on the interior of the steel silo, thermal insulation structures are currently added to the outside of the steel silo.

[0003] After searching, the authorization announcement number CN212376378U and the authorization announcement date 2021.01.19 disclose an above-ground thermal insulation steel plate silo, including a metal silo body, a bottom support ring is welded at the bottom of the metal silo body, the upper end of the metal silo body is a conical structure, a platform is arranged at the top of the cone at the upper end of the metal silo body, four support columns are vertically welded to the edge of the platform, a conical rain shelter is fixed above the support column by screws, a photovoltaic panel is inlaid on the upper surface of the conical rain shelter, and a wireless monitoring camera is fixed in the center of the top of the conical rain shelter by screws. The beneficial effects are: the bottom of the granary is not directly in contact with the ground, and a ventilation channel is provided, which can prevent underground moisture from penetrating upward to corrode and cool the metal silo body; the auger-type hoist can quickly complete the extraction and transportation of grain inside the metal silo body, and the operation is simple and convenient; the 360° camera can monitor the surrounding environment of the granary, which is convenient for timely discovery of safety hazards and convenient management.

[0004] The bottom of the steel silo in the prior art is usually conical, but the small cone angle cannot achieve the effect of making the materials converge to the lowest point of the silo bottom, and the large cone angle affects the storage capacity of the steel silo, which is inconvenient to use. For some temperature-sensitive materials, such as grain, although the prior art uses a structure with thermal insulation effect to perform passive insulation, the temperature inside the steel silo is easily affected by the heat of the material itself and the high temperature of the outside world, resulting in high temperature. For this reason, we provide a steel silo thermal insulation structure to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a heat-insulating structure for a steel silo, in which a scraper is rotated by a motor to move the material to the lowest point of the silo bottom so as to achieve the effect of completely discharging the material, and a water pump is used to allow cooling water to enter between the outer shell and the steel silo body to absorb heat to avoid excessively high temperatures inside the steel silo body, thereby solving the problem that the bottom of the steel silo in the prior art is usually conical, but the small cone angle cannot achieve the effect of making the material converge to the lowest point of the silo bottom, and the large cone angle affects the storage capacity of the steel silo, which is inconvenient to use. In addition, although the prior art uses a structure with heat-insulating effects for heat insulation, the temperature inside the steel silo is easily affected by the heat generated by the material itself and the high temperature of the outside world, resulting in high temperatures.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a heat insulation structure of a steel silo, comprising a steel silo body, a motor is fixed to the upper wall of the steel silo body, a rotating rod is fixed to the power output shaft of the motor, a scraper is symmetrically fixed to the outer peripheral wall of the bottom of the rotating rod, and the lower wall of the scraper is in contact with the lower wall inside the steel silo body;

[0008] An outer shell is fixed to the outside of the steel silo body, a water tank is arranged on the left side of the steel silo body, a connecting pipe is fixed to the upper wall of the water tank, and the other end of the connecting pipe is fixed to the top of the outer peripheral wall of the outer shell, a water pump is arranged on the right side of the water tank, and water pipes are fixed to the liquid inlet and outlet ends of the water pump.

[0009] The utility model is further configured such that the bottom of the steel silo body is conical, the outer peripheral wall of the shell and the upper wall of the steel silo body are fixed with a thermal insulation layer, and the lower wall of the shell is fixed with a plurality of legs.

[0010] The utility model is further configured such that a feed pipe is fixed on the upper side of the right side outer peripheral wall of the steel silo body, and the right end of the feed pipe is located outside the thermal insulation layer, and a temperature sensor is fixed on the upper wall inside the steel silo body.

[0011] The utility model is further configured such that a discharge pipe is fixed at the middle position of the lower wall of the steel plate silo body, and the lower end of the discharge pipe is located outside the thermal insulation layer, a conveyor is arranged below the discharge pipe, and a feed pipe of the conveyor is fixedly connected to the discharge pipe.

[0012] The utility model is further configured such that the other end of the water pipe at the liquid inlet end of the water pump is fixedly connected to the lower side of the outer peripheral wall of the shell, and the other end of the water pipe at the liquid outlet end of the water pump is fixedly connected to the water tank.

[0013] The utility model is further configured that a fan is fixed on the upper wall of the water tank, a protective net is fixed on the upper wall of the fan, and a perforation is opened at the position of the fan corresponding to the upper wall of the water tank.

[0014] The utility model is further configured that air outlet grooves are provided on the tops of the left and right side walls of the water tank, and dustproof nets are fixed on the left and right side walls of the water tank at the positions where the air outlet grooves are located.

[0015] The utility model has the following beneficial effects:

[0016] The utility model provides a motor and a scraper bar, and utilizes the motor to drive the rotating rod to rotate, so that the scraper bar rotates. Since the scraper bar contacts the lower wall inside the steel silo body, the material on the lower wall inside the steel silo body can be put into motion when the scraper bar rotates. Since the lower wall inside the steel silo body is conically arranged, even when the conical angle is small, the material can move to the lowest point of the lower wall inside the steel silo body under the rotation of the scraper bar, so that when the conical angle of the bottom of the steel silo body is small, the material can still be completely discharged to avoid material residue, thereby solving the problem that the steel silo bottom in the prior art is usually conically arranged, but the small conical angle cannot achieve the effect of making the material gather to the lowest point of the silo bottom, and the large conical angle affects the storage capacity of the steel silo, which is inconvenient to use.

[0017] The utility model is provided with a water tank and a water pump, and the space between the outer shell and the steel silo body is filled with cooling water, and the cooling water itself has a heat insulation effect. When the temperature inside the steel silo body is high, the water pump works to transport the cooling water in the water tank to between the outer shell and the steel silo body, and the cooling water absorbs the heat from the steel silo body and then enters the water tank for cooling. Compared with the prior art, the steel silo body is cooled by the circulation of cooling water to prevent the internal temperature of the steel silo body from being too high and affecting the materials, thereby solving the problem that although the prior art uses a structure with a heat preservation and heat insulation effect for heat insulation, the temperature inside the steel silo is easily affected by the heat of the material itself and the high temperature of the outside world to generate high temperature.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0028] See also Figure 1-3 The utility model is a heat-insulating structure for a steel silo, including a steel silo body 7, a motor 4 is fixed to the upper wall of the steel silo body 7, a rotating rod 401 is fixed to the power output shaft of the motor 4, and a scraper 401a is symmetrically fixed to the outer peripheral wall at the bottom of the rotating rod 401, and the lower wall of the scraper 401a is in contact with the lower wall inside the steel silo body 7. The above arrangement drives the rotating rod 401 to rotate through the operation of the motor 4, so that the scraper 401a rotates to move the material on the lower wall inside the steel silo body 7, and under the effect of the conical bottom of the steel silo body 7, the material moves to the discharge pipe 703 to completely discharge the material, thereby achieving the effect of still being able to discharge all the material when the conical angle of the bottom of the steel silo body 7 is small;

[0029] Specifically, the bottom of the steel silo body 7 is set in a conical shape, and the outer peripheral wall of the shell 701 and the upper wall of the steel silo body 7 are fixed with a heat insulation layer 5 for heat insulation, which can be made of polystyrene. The lower wall of the shell 701 is fixed with a plurality of legs 701a for supporting the shell 701;

[0030] A feed pipe 702 is fixed on the upper side of the right peripheral wall of the steel silo body 7, and the right end of the feed pipe 702 is located outside the thermal insulation layer 5. The feed pipe 702 is connected to an external feeding device for feeding materials into the steel silo body 7. A temperature sensor 704 is fixed on the upper wall inside the steel silo body 7 for detecting the temperature inside the steel silo body 7.

[0031] A discharge pipe 703 is fixed at the middle position of the lower wall of the steel silo body 7, and the lower end of the discharge pipe 703 is located outside the thermal insulation layer 5. A conveyor 6 is arranged below the discharge pipe 703, and the feed pipe 702 of the conveyor 6 is fixedly connected to the discharge pipe 703. The conveyor 6 can be a screw conveyor. With the above arrangement, when the material inside the steel silo body 7 is taken out, by operating the conveyor 6, the material inside the steel silo body 7 passes through the discharge pipe 703 and enters the conveyor 6, and the material is transported by the conveyor 6.

[0032] The operation process of this embodiment is as follows: when conveying materials to the steel silo body 7, the materials can be passed through the feed pipe 702 through external conveying equipment, and when conveying materials to the outside, the conveyor 6 can be operated, and the materials inside the steel silo body 7 pass through the discharge pipe 703 into the conveyor 6, and the materials are discharged under the operation of the conveyor 6. When there is no material output from the conveyor 6, the motor 4 is operated to drive the rotating rod 401 to rotate, so that the scraper 401a rotates, so that the materials on the lower wall of the steel silo body 7 are in motion and move to the middle, and then pass through the discharge pipe 703 into the conveyor 6 for transportation. Specific embodiment 2

[0033] See also Figure 1 , 2, 4 and 5 are the second embodiment of the utility model, which is based on the previous embodiment, but is different from the first embodiment in that: a shell 701 is fixed to the outside of the steel silo body 7, and the connection between the shell 701 and the steel silo body 7 is sealed and fixed for accommodating cooling water. A water tank 2 is arranged on the left side of the steel silo body 7 for storing cooling water and dissipating heat. A connecting pipe 202 is fixed to the upper wall of the water tank 2, and the other end of the connecting pipe 202 is fixed to the top of the outer peripheral wall of the shell 701. The interior of the connecting pipe 202 is communicated with the interior of the water tank 2. At the same time, the interior of the connecting pipe 202 is also communicated with the space between the shell 701 and the steel silo body 7. A water pump 3 is arranged on the right side of the water tank 2 for conveying cooling water. Water pipes 301 are fixed to the liquid inlet and liquid outlet of the water pump 3. The water pipe 301 at the liquid inlet end of the water pump 3 is communicated with the space between the shell 701 and the steel silo body 7, and the water pipe 301 at the liquid outlet end of the water pump 3 is communicated with the interior of the water tank 2;

[0034] Specifically, the other end of the water pipe 301 at the liquid inlet end of the water pump 3 is fixedly connected to the lower side of the outer peripheral wall of the housing 701, and the other end of the water pipe 301 at the liquid outlet end of the water pump 3 is fixedly connected to the water tank 2;

[0035] A fan 1 is fixed on the upper wall of the water tank 2, which is used to generate airflow and act on the coolant inside the water tank 2 to dissipate heat. A protective net 101 is fixed on the upper wall of the fan 1 to provide protection for the fan 1. The protective net 101 can be set to a metal material. A perforation 204 is opened at the position of the fan 1 corresponding to the upper wall of the water tank 2 to provide a movement channel for the airflow generated by the fan 1.

[0036] The tops of the left and right side walls of the water tank 2 are provided with air outlet grooves 203. The airflow acting on the coolant in the water tank 2 carries the heat through the air outlet grooves 203 and the dustproof net 201 and is discharged to the outside environment. The dustproof nets 201 are fixed to the left and right side walls of the water tank 2 at the positions where the air outlet grooves 203 are located, so as to prevent foreign debris and dust from entering the water tank 2.

[0037] The rest of the structure is the same as that of the first embodiment;

[0038] The operation process of this embodiment is as follows: the temperature sensor 704 detects the temperature inside the steel silo body 7. When the temperature inside the steel silo body 7 reaches a preset value, the controller controls the water pump 3 and the fan 1 to work. The water pump 3 transports the cooling water inside the water tank 2 to between the outer shell 701 and the steel silo body 7. At this time, the cooling water flows and absorbs heat to cool the material inside the steel silo body 7. The coolant then passes through the connecting pipe 202 into the water tank 2, and an airflow is generated under the action of the fan 1. The airflow acts on the cooling water inside the water tank 2 and carries the heat through the air outlet groove 203 and the dustproof net 201 to be discharged to the outside.

[0039] In addition, the temperature sensor 704, fan 1, water pump 3, motor 4 and conveyor 6 in the thermal insulation structure of the steel silo are electrically connected to the single-chip microcomputer in the controller through conductive wires, and the single-chip microcomputer in the controller is electrically connected to the external power supply through conductive wires. At the same time, the electrical appliances in the thermal insulation structure of the steel silo are all existing technologies, and their models are not limited here.
