Description

Technical Field

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

[0002] Fly ash is a residue produced after the incineration of municipal solid waste. Due to its content of heavy metals, dioxins, and other harmful substances, it is classified as hazardous waste and must undergo proper stabilization / solidification treatment to meet site acceptance standards before it can be safely landfilled or recycled. In actual industrial production, fly ash is usually temporarily stored in silos (or storage bins, ash hoppers) and quantitatively fed downstream to conveying equipment or mixing and solidification devices through the discharge port at the bottom. Due to the physical properties of fly ash and its tendency to absorb moisture, it is highly susceptible to moisture absorption and caking in the silo, especially under conditions of high humidity or prolonged storage, increasing the adhesion and internal friction between materials. This caking phenomenon causes a stable "bridging" blockage structure to form above the silo discharge port, resulting in poor material flow. Therefore, we propose a fly ash solidification device. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a fly ash solidification device to solve the problems existing in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A fly ash solidification device includes a storage bin and a gate for opening and closing the outlet of the storage bin. A scraper is provided on the gate, and the scraper is positioned so that it can scrape off fly ash clumps from the inner wall of the storage bin and near the outlet during the opening and closing of the gate.

[0006] Preferably, a support plate is also connected between the scraper and the gate to enhance the structural strength of the scraper.

[0007] Preferably, the scraper is disposed near the rotating end of the gate, and the angle between the scraper and the gate is 15-45 degrees.

[0008] Preferably, the side length of the scraper near its drive connection component is less than the side length of the corresponding side of the gate.

[0009] Preferably, there is a pair of gates, symmetrically arranged to cover the discharge port; the device also includes a drive mechanism, which includes a cylinder, a transmission crossbar and a connecting rod. The cylinder is fixed on the storage bin, and its output end is connected to the transmission crossbar. The two ends of the transmission crossbar are respectively hinged to a pair of gates through the connecting rod, which is used to drive the pair of gates to move synchronously towards or away from each other.

[0010] Preferably, the storage bin is connected to side plates on both sides, and a rotating shaft is installed on the side plates via bearings, with a gate plate fixedly connected to the rotating shaft.

[0011] Preferably, the storage silo is also equipped with at least one layer of baffles for breaking up fly ash agglomerates.

[0012] Preferably, the stop levers include a first stop lever and a second stop lever that are arranged in an overlapping manner.

[0013] Preferably, the cross-sectional shape of the stop lever is triangular.

[0014] This invention provides a fly ash curing device. It has the following beneficial effects:

[0015] 1. The gate is equipped with a scraper at a certain angle, which can automatically scrape off the caking fly ash on the inner wall of the storage bin and near the discharge port during each opening and closing process, effectively preventing the occurrence of "bridging" phenomenon and ensuring continuous and uniform discharge of fly ash.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this utility model, not all of it. Based on this utility model, all other inventions obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] See attached document Figure 1-4A fly ash solidification device includes a storage silo 1, a pair of gates 2 rotatably mounted on the storage silo 1 and covering the discharge port of the storage silo 1, and a pair of cylinders 11 installed on both sides of the storage silo 1. The output direction of the cylinders 11 is consistent with the discharge direction, and the cylinders 11 are located in the middle of the side of the storage silo 1. A transmission crossbar 12 is connected to the output end of the cylinders 11. The transmission crossbar 12 is perpendicular to the cylinders 11 and extends to both sides. A connecting rod 13 is hinged at the extension ends of the transmission crossbar 12 on both sides. The other end of the connecting rod 13 is hinged to the corresponding gate 2. When the output end of the cylinder 11 is lifted, the transmission crossbar 12 is driven to move along the discharge direction of the storage silo 1, so that the pair of gates 2 unfold to both sides to realize the discharge.

[0023] A scraper 21 is connected to the gate plate 2. The angle between the scraper 21 and the gate plate 2 is 15-45 degrees. The connection point of the scraper 21 is close to the rotating shaft end of the gate plate 2, and the side length of the scraper 21 near the connecting rod 13 is half the side length of the gate plate 2. A support plate 22 is also connected between the scraper 21 and the gate plate 2 to enhance the structural strength of the scraper. The scraper 21 on the gate plate 2 can scrape off the fly ash caking in the storage bin 1 during each opening and closing of the gate, preventing the accumulation of ash from forming a "bridging" blockage structure. The support plate 22 enhances the structural strength and deformation resistance of the scraper 21, ensuring its long-term effectiveness.

[0024] Side plates 14 are connected to the storage bins 1 on both sides of the cylinder 11. The side plates 14 extend out of the corner of the storage bins 1, and the same rotating shaft 15 is connected to the extended end of the side plates 14 via bearings. A gate 2 is also fixedly connected to the rotating shaft 15. The two gates 2 cover the discharge port of the storage bins 1.

[0025] A first stop bar 16 and a second stop bar 17 are provided in the storage bin 1. The first stop bar 16 and the second stop bar 17 are overlapped and arranged in layers in the storage bin 1. The cross sections of the first stop bar 16 and the second stop bar 17 are triangular.
