Description

Technical Field

[0001] This utility model belongs to the field of steel silo technology, specifically relating to a pressure regulating device inside a steel silo. 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. Controlled atmosphere storage (CAS) refers to a grain storage technology that artificially alters the composition of normal atmospheric gases or adjusts the original gas ratios to control a specific gas concentration within a certain range and maintain it for a certain period, thereby achieving insect control, mold inhibition, and delaying changes in grain quality. In the application of CAS, the airtightness of the storage facility is a crucial factor affecting the effectiveness of CAS.

[0003] A shallow circular silo pressure regulating device with patent number CN214676663U can significantly slow down the rate of nitrogen concentration decrease in the silo space, silo door, and ventilation duct below the silo by reducing the range of pressure changes inside the silo, thereby reducing the number of times the gas is replenished.

[0004] However, in actual operation, although most of the shallow circular silo pressure regulating devices in the above-mentioned utility model are equipped with corresponding pressure regulating valves on the silo body, which can adjust the pressure inside the silo according to the actual situation, sometimes the pressure inside the silo will rise rapidly when the grain has produced a large amount of fermentation gas. At this time, it is difficult for the operator to detect the rapid change in pressure in time, so they cannot operate the pressure regulating valve in time, which can easily damage the silo wall. Utility Model Content

[0005] The purpose of this invention is to provide a pressure regulating 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 pressure regulating device for steel silos, comprising...

[0007] The placement seat is equipped with the main structure, which includes the storage body;

[0008] The top of the container is equipped with a top cover, on which the pressure regulating valve body and the alarm body are installed. The alarm body is located on one side of the pressure regulating valve body.

[0009] An alarm mechanism is provided on the top cover. The alarm mechanism includes a connecting block. A connecting block is fixedly connected to each side of the pressure regulating valve body. A mounting frame is fixedly connected to the connecting block.

[0010] A guide rod is slidably connected to the placement frame. The bottom end of the guide rod extends into the interior of the compartment and is connected to a pressure plate. A spring is wound around the guide rod. One end of the spring is fixedly connected to the placement frame, and the other end of the spring is fixedly connected to the guide rod.

[0011] Optionally, the silo body is equipped with multiple reinforcing hoops, and multiple columns are provided between the reinforcing hoops.

[0012] Optionally, the multiple reinforcing hoops are linearly distributed with equal spacing, and the multiple columns are distributed in a ring with equal spacing.

[0013] Optionally, the bottom of the silo is funnel-shaped, and a discharge pipe is fixedly connected to the bottom of the silo.

[0014] Optionally, the bottom of the mounting base is provided with a support mechanism, which includes support rods. Multiple support rods are fixedly connected to the bottom of the mounting base, and a base is fixedly connected to the bottom of each support rod.

[0015] Optionally, a tie rod is fixedly connected between each of two adjacent support rods, and the tie rod is set at an angle.

[0016] Optionally, the top of the guide rod extends through the mounting frame, and the top of the guide rod is arc-shaped.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model, through the arrangement of a mounting base, a silo body, a discharge pipe, a top cover, a pressure regulating valve body, a connecting block, a mounting frame, a guide rod, a spring, and an alarm body, allows for convenient placement of the silo body via the mounting base. After grain is stored inside the silo body, it can be discharged through the discharge pipe as needed. When the grain stored inside the silo undergoes significant fermentation and produces gas, the internal pressure rises rapidly. When the internal pressure reaches a certain level, it drives the guide rod, causing it to move upwards and compressing the spring. This compresses the spring until the top of the guide rod presses the button on the alarm body, directly triggering the alarm and emitting an alarm signal. This allows operators to promptly detect rapid pressure changes and adjust the pressure regulating valve accordingly, thus reducing damage to the silo walls.

[0019] This invention, by setting up a pressure plate, allows for the application of pressure to the pressure plate first when the internal pressure of the chamber increases to a certain level during actual use, according to the above operation. Only after the pressure plate is subjected to pressure will it transmit the force to the guide rod. In this process, the pressure plate increases the contact surface with the air pressure thrust inside the chamber, making it easier to drive the guide rod and making the application of the alarm body more convenient.

Detailed Implementation

[0026] The present invention will be further described below with reference to the embodiments.

[0027] 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.

[0028] Please see Figure 1-5This utility model provides a pressure regulating device for a steel silo, including a mounting base 1, a main body 2 on the mounting base 1, a silo body 201 on the main body 201, a top cover 4 on the top of the silo body 201, a pressure regulating valve body 6 and an alarm body 8 on the top cover 4, the alarm body 8 being located on one side of the pressure regulating valve body 6, and an alarm mechanism 7 on the top cover 4, the alarm mechanism 7 including a connecting block 701, a connecting block 701 being fixedly connected to each side of the pressure regulating valve body 6, a mounting frame 702 being fixedly connected to the connecting block 701, a guide rod 703 being slidably connected to the mounting frame 702, the bottom end of the guide rod 703 extending into the silo body 201 and connected to a pressure plate 705, a spring 704 being wound around the guide rod 703, one end of the spring 704 being fixedly connected to the mounting frame 702, and the other end of the spring 704 being fixedly connected to the guide rod 703.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, multiple reinforcing hoops 202 are installed on the silo body 201, and multiple columns 203 are provided between the multiple reinforcing hoops 202. The multiple reinforcing hoops 202 are linearly distributed with equal spacing, and the multiple columns 203 are circularly distributed with equal spacing. The reinforcing hoops 202 and columns 203 are used to improve the overall stability of the silo wall of the silo body 201.

[0030] Specifically, such as Figure 2 As shown, the bottom of the silo 201 is funnel-shaped, and a discharge pipe 3 is fixedly connected to the bottom of the silo 201. The discharge pipe 3 is used to facilitate the discharge of materials inside the silo 201.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the bottom of the mounting base 1 is provided with a support mechanism 5, which includes support rods 501. Multiple support rods 501 are fixedly connected to the bottom of the mounting base 1, and a base 502 is fixedly connected to the bottom of the support rods 501 to facilitate the fixed support of the entire device. A tie rod 503 is fixedly connected between each of two adjacent support rods 501, and the tie rod 503 is inclined to improve the stability of the support rods 501.

[0032] Specifically, such as Figure 4 and Figure 5 As shown, the top of the guide rod 703 passes through the mounting frame 702, and the top of the guide rod 703 is arc-shaped, so that the guide rod 703 can better press the button on the alarm body 8.

[0033] The working principle and usage process of this utility model are as follows: During use, the mounting base 1 facilitates the placement of the silo body 201, while the support rod 501 and base 502 provide stable support for the entire device. Simultaneously, after storing grain inside the silo body 201, it can be discharged through the discharge pipe 3 as needed. When a large amount of gas is generated from the fermentation of the grain stored inside the silo body 201, the internal pressure of the silo body 201 rises rapidly. When the internal pressure reaches a certain level, it drives the guide rod 703, causing it to move upwards. Simultaneously, the spring 704 is compressed until the top of the guide rod 703 presses the button on the alarm body 8. This directly triggers the alarm body 8, issuing the corresponding alarm information, allowing the operator to promptly detect the rapid change in air pressure and operate the pressure regulating valve in time, thereby reducing damage to the silo walls.

[0034] In actual use, according to the above operation, when the internal pressure of the chamber 201 increases to a certain level, it will first apply pressure to the pressure plate 705. After the pressure plate 705 is subjected to pressure, it will then transmit the force to the guide rod 703. In this process, the pressure plate 705 will increase the contact surface with the air pressure thrust inside the chamber, thus making it easier to drive the guide rod 703 and making the application of the alarm body 8 more convenient.

[0035] 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.
