Description

Technical Field

[0001] This utility model belongs to the field of steel silo technology, specifically relating to a thermal expansion and contraction compensation device for steel silos. Background Technology

[0002] Steel silos, as a commonly used bulk grain storage facility, are widely adopted by the grain industry both domestically and internationally due to their advantages such as low investment, short construction period, and recyclability. A typical steel silo consists of a cylindrical hollow tube at the top and a funnel-shaped discharge assembly at the bottom, supported by multiple support rods for easy installation.

[0003] A powder grain storage silo with patent number CN202663825U features a bottom conical hopper directly beneath the silo top. A ventilation and aeration pipe with several through holes is radially arranged on the bottom conical hopper and fixedly connected to it. The ventilation and aeration pipes are radially welded to the bottom of the bottom conical hopper, arranged in a ring shape. The pipes are semi-open, with alternating long and short sections; the opening ratio decreases closer to the center of the bottom conical hopper. A pressure regulating valve and a dust collector are installed on the silo top. This design simplifies the structure, makes it easier to use, saves costs, increases the storage time of powder grains, and facilitates unloading.

[0004] However, in actual operation, the grain storage silos described in the aforementioned utility model typically have their storage structures placed on prefabricated foundations. Since the storage structures and foundations are made of different materials, their coefficients of expansion differ. When the steel plates of the storage structure expand or contract due to temperature changes, the foundation cannot expand or contract synchronously. This results in the steel plates being constrained and generating significant internal stress, causing deformation of the storage structure and, in severe cases, even destruction. This damage is particularly severe in regions with large temperature differences, such as the Northwest, posing significant safety hazards and seriously threatening the normal use of the storage structures. Utility Model Content

[0005] The purpose of this invention is to provide a thermal expansion and contraction compensation device for steel silos to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermal expansion and contraction compensation device for steel silos, comprising a mounting base, a silo body mounted on the mounting base, a discharge pipe fixedly connected to the bottom of the silo body, a support mechanism mounted on the mounting base, the support mechanism comprising a connecting block, multiple connecting blocks fixedly connected to the mounting base, a compensation limiting mechanism disposed inside the connecting block, the compensation limiting mechanism comprising a motor, a motor disposed inside the connecting block, a lead screw connected to the drive end of the motor, the lead screw being rotatably connected to the inside of the connecting block, a guide rod slidably connected inside the connecting block, the guide rod extending into the inside of the mounting base and connected to a limiting block, the limiting block being slidably connected to the inside of the connecting block.

[0007] Optionally, the bottom of the silo is funnel-shaped, and a discharge pipe is fixedly connected to the bottom of the silo.

[0008] Optionally, the overall shape of the silo is cylindrical, and the silo is provided with multiple reinforcing hoops, which are linearly distributed at equal intervals.

[0009] Optionally, a support column is fixedly connected to the bottom of the connecting block, and a base is fixedly connected to the bottom of the support column.

[0010] Optionally, an elastic abutment is fixedly connected to the limit block, and the elastic abutment abuts against the chamber body.

[0011] Optionally, the top of the silo is equipped with a protective mechanism, which includes columns. Multiple columns are fixedly connected around the top of the silo, and protective frames are fixedly connected to the columns.

[0012] Optionally, the protective frame is ring-shaped, and there are multiple protective frames, which are linearly distributed at equal intervals.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model, by setting up a mounting base, a silo, a discharge pipe, a connecting block, a support column, a base, a motor, a lead screw, a guide rod, and a limiting block, allows the user to easily fix the entire mounting base in place using the support column and base. Then, materials can be fed into the silo, and materials can be discharged through the discharge pipe. Depending on the situation, the motor inside the connecting block can be powered on, causing the lead screw to rotate. As the lead screw rotates, it drives the guide rod to move back and forth, which in turn moves the limiting block until the limiting component is pressed against the outer wall of the silo. Therefore, when the silo expands or contracts due to temperature changes, the limiting mounting component on the outside of the silo can move synchronously, always providing appropriate limiting contact, reducing the internal stress on the silo's steel plate, preventing deformation, and ensuring the normal use of the silo.

[0015] This invention, by setting an elastic abutment piece, in actual operation, as the limiting block moves, the elastic abutment piece will move synchronously, thus allowing the elastic abutment piece to abut and limit the outer wall of the container first. This reduces the wear on the limiting block, and at the same time, due to the action of the elastic abutment piece, it further plays a buffering and protective role in limiting the outer wall of the container.

Detailed Implementation

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figure 1-5This utility model provides a thermal expansion and contraction compensation device for steel silos, including a mounting base 1, a silo body 2 on the mounting base 1, a discharge pipe 3 fixedly connected to the bottom of the silo body 2, a support mechanism 5 on the mounting base 1, the support mechanism 5 including a connecting block 501, multiple connecting blocks 501 fixedly connected to the mounting base 1, a compensation limiting mechanism 6 inside the connecting block 501, the compensation limiting mechanism 6 including a motor 601, the motor 601 inside the connecting block 501, a lead screw 602 connected to the transmission end of the motor 601, the lead screw 602 rotatably connected to the inside of the connecting block 501, a guide rod 603 slidably connected inside the connecting block 501, the guide rod 603 extends into the inside of the mounting base 1 and is connected to a limiting block 604, the limiting block 604 slidably connected to the inside of the connecting block 501.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, the bottom of the silo 2 is funnel-shaped, and a discharge pipe 3 is fixedly connected to the bottom of the silo 2. The discharge pipe 3 is used to facilitate the discharge of materials inside the silo 2.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the overall shape of the silo body 2 is cylindrical, and multiple reinforcing hoops 4 are provided on the silo body 2. The multiple reinforcing hoops 4 are linearly distributed at equal intervals. The reinforcing hoops 4 are used to improve the overall stability of the silo body 2.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, a support column 502 is fixedly connected to the bottom of the connecting block 501, and a base 503 is fixedly connected to the bottom of the support column 502. The support column 502 and the base 503 facilitate the fixed placement of the entire device.

[0028] Specifically, such as Figure 5 As shown, an elastic abutment piece 605 is fixedly connected to the limiting block 604, and the elastic abutment piece 605 abuts against the chamber body 2. The elastic abutment piece 605 serves to buffer the limiting abutment of the limiting block 604.

[0029] Specifically, such as Figure 4 As shown, the top of the storage body 2 is provided with a protective mechanism 7. The protective mechanism 7 includes columns 701. Multiple columns 701 are fixedly connected around the top of the storage body 2, and protective frames 702 are fixedly connected to the multiple columns 701. The protective frames 702 are ring-shaped, and there are multiple protective frames 702. The multiple protective frames 702 are linearly distributed at equal intervals. Through the columns 701 and the protective frames 702, the top of the storage body 2 is protected and surrounded.

[0030] The working principle and usage process of this utility model are as follows: In actual operation, the user can use the support column 502 and the base 503 to easily fix the entire placement seat 1. Then, in actual operation, the corresponding materials can be put into the inside of the silo 2. When discharge is required later, the materials can be discharged through the discharge pipe 3. According to the actual situation, the motor 601 inside the connecting block 501 can be connected to the power supply. The motor 601 rotates and drives the lead screw 602 to rotate together. As the lead screw 602 rotates, it drives the guide rod 603 to move back and forth. The guide rod 603 drives the limiting block 604 to move together until the limiting component just touches and squeezes the outer wall of the silo 2. Thus, when the silo 2 expands and contracts due to temperature, the limiting placement component on the outside of the silo 2 can move synchronously, always providing appropriate limiting contact to the silo 2, reducing the large internal stress generated by the constraint of the steel plate of the silo 2, avoiding deformation of the silo 2, and ensuring the normal use of the silo 2.

[0031] Furthermore, in actual operation, as the limiting block 604 moves, the elastic abutment piece 605 will move synchronously, thus causing the elastic abutment piece 605 to abut and limit the outer wall of the chamber 2 first. This reduces the wear on the limiting block 604, and at the same time, due to the action of the elastic abutment piece 605, it plays a buffering and protective role in limiting the outer wall of the chamber 2.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
