Description

Technical Field

[0001] This utility model relates to the field of industrial equipment technology, specifically to a fly ash steel silo ash discharge device. Background Technology

[0002] Fly ash steel silos are large bulk material storage containers, typically composed of a steel shell and internal support structure, manufactured using welding methods. They offer advantages such as large storage capacity, rapid unloading, long service life, and low overall cost, while also possessing high strength and rigidity, capable of withstanding significant pressure loads. The design of fly ash steel silos is flexible and reliable, allowing for customization in size and capacity to meet different application scenarios and customer requirements for storing high-temperature materials. Furthermore, they feature a specially designed manhole cover for airtight protection, preventing dust pollution, and are equipped with ladders, guardrails, and safety doors to enhance worker safety during access.

[0003] To better store the fly ash needed for production and avoid open-air storage that affects the environment and material efficiency, as well as the dangers of personnel management, steel silos for fly ash have been built. However, the current ash discharge device of the steel silos consists of multiple discharge ports that are homogenized through a low-pressure air pipe generated by a 0.2 MPa Roots blower before being transported. Since fly ash is a raw material for silicate products, the ambient temperature during winter storage causes condensation to form in the pipes, resulting in caking of the raw material. This leads to uneven homogenization, long homogenization time, poor conveying, and slow ash discharge. Utility Model Content

[0004] The purpose of this utility model is to provide a fly ash steel silo ash discharge device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fly ash steel silo ash discharge device, comprising a storage frame, a Roots blower, and a screw air compressor, and further comprising:

The inner wall of the connecting pipe is connected to a discharge pipe, and a regulating valve is set on the outside of the discharge pipe. The inner wall of the discharge pipe is connected to an ash discharge pipe, and a hoist is set at one end of the ash discharge pipe.

[0007] A low-pressure air pipe is installed on one side of the Roots blower. The inner wall of the low-pressure air pipe is connected to a first fixed pipe, and the other end of the first fixed pipe is connected to the inner wall of the ash discharge pipe.

[0008] A high-pressure air pipe is installed on one side of the screw air compressor. The inner wall of the high-pressure air pipe is connected to a second fixed pipe, and the other end of the second fixed pipe is connected to the inner wall of the ash discharge pipe. The second fixed pipe is connected to the inner wall of the connecting pipe through a flexible hose.

[0009] Preferably, a mounting frame is installed on the outside of the storage frame, and multiple mounting blocks are fixed on one side of the mounting frame.

[0010] Preferably, the inner wall of the mounting block is threaded with two horizontally arranged long bolts, and the outer side of the long bolts is provided with nuts.

[0014] Preferably, a connecting ring is fixed to the top of the support block, and the inner wall of the connecting ring is fixed to the outer side of the second fixing tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, based on the original low-pressure air pipe homogenization and ash discharge system using only a 0.2 MPa Roots blower, adds a 75 kW screw air compressor with a set pressure of 0.6 MPa. This compressor is connected to the existing homogenization and ash discharge pipes, enabling both low-pressure and high-pressure homogenization and conveying. The raw materials are first homogenized via the 0.2 MPa low-pressure air pipe, and then the fly ash is further homogenized and conveyed via the 0.6 MPa high-pressure air pipe. This saves homogenization time and improves ash discharge efficiency in the steel silo ash discharge device, thus solving the problems of homogenization and ash discharge.
