Description

Technical Field

[0001] The utility model relates to the technical field of fly ash, in particular to a steel silo for storing fly ash. Background Art

[0002] Fly ash is the fine dust produced during the combustion of coal in coal-fired power plants. It primarily originates from solid waste captured from the flue gases following coal combustion. If left untreated, fly ash can generate dust and pollute the atmosphere. Discharge into waterways can cause siltation, and the toxic chemicals it contains can pose a threat to humans and other organisms. However, fly ash also has potential for resource utilization, such as as a concrete admixture. Furthermore, its pozzolanic activity allows it to be used in the production of building materials, such as fly ash concrete blocks. This is crucial for conserving natural resources, saving energy, reducing the environmental impact of waste, and promoting the development of new building materials. Therefore, fly ash needs to be stored and utilized.

[0003] Prior art, such as the patent publication number "CN 214932600 U," discloses a large-scale fly ash storage device. This utility model utilizes a heating plate installed on the top of the silo and an insulation layer embedded in the silo's sidewalls. This facilitates maintaining the temperature inside the silo through the heating plate, thereby preventing excessive humidity inside the silo from causing fly ash to agglomerate, which would affect subsequent recycling and reuse. The above prior art prevents fly ash agglomeration by controlling the temperature inside the silo. However, when the fly ash is transported to the silo for storage, incompletely burned fly ash will agglomerate. If the agglomerated fly ash is directly stored, when the humidity is too high, the agglomerated fly ash will absorb more fly ash to form large agglomerates, which is detrimental to the subsequent transportation and utilization of the fly ash. Utility Model Content

[0004] The utility model aims to provide a steel silo for storing fly ash, so as to solve the problem that the existing steel silo directly stores fly ash without pre-crushing the fly ash.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a steel plate silo for storing fly ash, comprising a silo body, the top end of the inner wall of the silo body is connected to a feed port, the bottom end of the silo body is connected to a discharge port, the top end of the inner wall of the silo body is connected to a drive disk, the outer edge of the drive disk is connected to one end of a first screen drum, the other end of the first screen drum is connected to the inner wall of the silo body and the discharge port is located at the center of the first screen drum, the inner edge of the drive disk is connected to a second screen drum, a rotating assembly for driving the second screen drum to rotate is provided in the drive disk, the second screen drum is connected to the feed port, the side walls of the first screen drum and the second screen drum are both screens, and there is a certain gap between the first screen drum and the second screen drum.

[0006] The working principle of the utility model is as follows: fly ash enters the first sieve drum through the feed port, at which time the rotating assembly drives the first sieve drum to rotate, and the fly ash leaks from the first sieve drum to the second sieve drum. The fly ash is crushed by the mutual friction between the first sieve drum and the second sieve drum, and then falls from the second sieve drum into the silo after becoming powder.

[0007] The beneficial effects of the utility model are as follows: 1. The steel silo adopts the sleeve assembly to ensure that the fly ash is not easy to clump during storage, thereby improving storage efficiency. 2. By preventing the fly ash from clumping during storage, it ensures smooth discharge, reduces the blockage problem caused by agglomeration, and improves discharge efficiency.

[0008] Furthermore, a plurality of steel balls are provided between the first sieve drum and the second sieve drum, so that the fly ash can be crushed more thoroughly.

[0009] Furthermore, the rotating assembly is a motor, a disc is provided at the center of the driving disc, an output shaft of the motor is connected to the disc, and the first sieve drum is connected to the disc. By driving the disc with the motor, the first sieve drum can rotate the fly ash at a uniform speed.

[0010] Furthermore, a fixed plate is connected to the top of the inner wall of the silo, symmetrically arranged with the drive plate. The first and second sieve drums are connected to the fixed plate. A through hole of the same size as the feed opening is provided at the center of the fixed plate, communicating with the first sieve drum. The provision of the fixed plate prevents the first and second sieve drums from being directly connected to the inner wall of the silo, potentially damaging the silo.

[0011] Furthermore, the mesh density of the second sieve drum is smaller than that of the first sieve drum. By setting the density, even smaller lumps of fly ash can be crushed by friction.

[0012] Furthermore, the inner bottom of the silo is provided with an inclined plate, the bottom end of which is located at the discharge port. A hydraulic cylinder is connected to the inner bottom of the silo, and the output shaft of the hydraulic cylinder is vertically connected to the top and bottom of the inclined plate. The arrangement of the hydraulic cylinder and the inclined plate allows fly ash to pass quickly through the discharge port. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The embodiment is basically as shown in the attached Figure 1 -Attached Figure 2 As shown: a steel plate silo for storing fly ash, including a silo body 2, a driving disc 4, a fixed disc, a first sieve drum 5 and a second sieve drum 10. The bottom of the silo body 2 is fixedly connected to a base 7, and the base 7 is fixedly connected to the ground. An inclined plate 9 is provided at the inner bottom of the silo body 2. The right end of the inclined plate 9 is rotatably connected to the bottom of the silo body 2 and is located at the discharge port 6. A hydraulic cylinder 8 is connected to the inner bottom of the silo body 2. The output shaft of the hydraulic cylinder 8 is vertically upward and fixedly connected to the left end of the inclined plate 9. The top of the left inner wall of the silo body 2 is connected to the feed port 1, and the bottom right end of the silo body 2 is connected to the discharge port 6. The fixed disc is fixedly connected to the top of the left inner wall of the silo body 2. A through hole of the same size as the feed port 1 is provided at the center of the fixed disc. The driving disc 4 is fixedly connected to the top of the right inner wall of the silo body 2. A disc is actively connected at the center, and a motor 3 is fixedly connected to the driving disc 4. The output shaft of the motor 3 horizontally passes through the driving disc 4 and is fixedly connected to the center of the disc. The fixed disc and the driving disc 4 are symmetrically arranged. The outer edge of the driving disc 4 is fixedly connected to the right end of the first sieve drum 5, and the left end of the first sieve drum 5 is fixedly connected to the outer edge of the fixed disc. The outer edge of the disc is fixedly connected to the right end of the second sieve drum 10, and the left end of the second sieve drum 10 is slidingly connected to the inner edge of the fixed disc. The second sieve drum 10 is connected to the feed port 1, and the side walls of the first sieve drum 5 and the second sieve drum 10 are both sieves.

There is a certain gap between the first sieve drum 5 and the second sieve drum 10, and steel balls 11 are provided between the first sieve drum 5 and the second sieve drum 10.

[0018] The specific implementation process is as follows: the fly ash enters the first screen drum 5 through the feed port 1, at this time the motor 3 is started, and the output shaft of the motor 3 drives the disc to rotate, so that the first screen drum 5 rotates, and the fly ash leaks from the first screen drum 5 to the second screen drum 10. The fly ash is in the gap between the first screen drum 5 and the second screen drum 10. As the first screen drum 5 rotates, the steel balls 11 continuously squeeze and crush the fly ash. In addition, the mutual friction and crushing between the first screen drum 5 and the second screen drum 10 causes the fly ash to become powder and fall from the second screen drum 10 into the silo 2. When the fly ash needs to be transported out, the hydraulic cylinder 8 is started, and the telescopic end of the hydraulic cylinder 8 drives the inclined plate 9 to move up and down, so that the fly ash can be quickly transported out from the discharge port 6.
