Description

Technical Field

[0001] The utility model relates to the field related to fly ash, and specifically relates to a conveying device for calorific value fly ash. Background Art

[0002] Fly ash is a fine-grained residue collected from the flue gas of coal-fired power plants. It is mainly composed of oxides of elements such as silicon, aluminum, iron, and calcium, and appears gray or gray-black in appearance. During the coal combustion process, inorganic minerals melt at high temperatures and then quickly cool and solidify to form these tiny, porous glassy spherical particles. With the progress of technology and the enhancement of environmental awareness, the comprehensive utilization of fly ash has received more and more attention. Through scientific methods and technical means, fly ash can be transformed into a variety of useful products.

[0003] Some current calorific value fly ash conveying devices in the market often face challenges in meeting the complex production batching requirements in actual applications. Especially in the modern industrial production environment that pursues high efficiency and energy conservation, these traditional devices often fail to fully consider the particularity of fly ash as a high-calorific value raw material. Their conveying efficiency and accuracy are insufficient, restricting the potential for improving the calorific value of raw materials, and thus failing to effectively achieve the goal of reducing coal consumption and optimizing energy utilization.

[0004] Currently, during the process of conveying calorific value fly ash to the powder silo, the commonly used method is to directly inject it through the ash discharging pipe by a tank truck. Currently, 2 ash discharging ports are designed, with low efficiency and difficulty in meeting the fast-paced requirements of the production line. At the same time, the connection process between the ash discharging pipe and the powder silo inlet pipe is cumbersome and complex, not only taking a long time, but also increasing the operation difficulty and error risk, seriously affecting the fast and efficient docking between the tank truck and the powder silo.

[0005] Therefore, we make improvements and propose a conveying device for calorific value fly ash. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a conveying device for calorific value fly ash, which solves the problems mentioned in the background art.

[0007] In order to achieve the above utility model purpose, the utility model provides the following technical solutions:

[0008] A conveying device for calorific value fly ash to solve the above problems.

[0009] Specifically, this application is as follows:

[0010] It includes a powder silo, a conveying trough is arranged on the lower side of the powder silo, an ash inlet pipe is arranged outside the powder silo, and the lower end of the ash inlet pipe is connected with an ash discharging pipe. A connecting mechanism is arranged between the ash inlet pipe and the ash discharging pipe;

[0011] The lower surface of the powder bin is connected with an inclined chute, and the lower end of the inclined chute is connected with a rotor weigher. The lower discharge port of the rotor weigher is communicated with a conveying chute, and a support frame is fixedly installed on the lower surface of the rotor weigher.

[0012] As a preferred technical solution of the present application, a plurality of ash inlet pipes are provided, and all the plurality of ash inlet pipes are communicated with the powder bin.

[0013] As a preferred technical solution of the present application, the connecting mechanism includes a connecting piece and a connecting head. The connecting piece is fixedly connected to the ash discharging pipe, and the connecting head is fixedly connected to the ash discharging pipe. A clamping structure is formed between the connecting piece and the connecting head.

[0014] As a preferred technical solution of the present application, an installation groove is formed on the outer surface of the connecting head. Sliding grooves are formed on the inner walls on both the upper and lower sides of the connecting piece, and clamping blocks are slidably connected inside the sliding grooves. The lower ends of the clamping blocks are inclined, and the lower ends of the clamping blocks are connected to the installation groove in a clamping manner.

[0015] As a preferred technical solution of the present application, a threaded rod is rotatably connected inside the connecting piece, and one end of the threaded rod extends into the sliding groove. The threaded rod is threadedly connected to the clamping block, and a rotating handle is fixedly installed on the surface of the other end of the threaded rod.

[0016] As a preferred technical solution of the present application, a sealing ring is fixedly installed on one side surface of the connecting head, and a sealing groove is formed inside the connecting piece. A sealing gasket is adhesively connected inside the sealing groove, and the sealing ring is connected to the sealing groove in a clamping manner.

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

[0018] In the solution of the present application:

[0019] 1. By providing the inclined chute and the rotor weigher, and adding an ash inlet pipe outside the powder bin (for discharging fly ash from the tanker), through the metering of the rotor weigher and the conveying of the inclined chute to the conveying chute, the rotor weigher can achieve high-precision metering of the calorific value fly ash material. The fly ash with calorific value in the external batching of the mill can fully meet the production requirements; adding 2 - 2.5% in the conveying chute, taking advantage of the calorific value characteristics of the fly ash, through reasonable batching, it can not only meet the production batching requirements but also increase the calorific value of the raw meal to achieve the purpose of reducing coal consumption, and can reduce the actual coal consumption; at the same time, a mature and stable external batching process system can be formed in the external batching of the mill to ensure the continuous operation of production, improve the hourly output of the vertical mill, and reduce the power consumption of the raw meal process.

[0020] 2. By adding a dust inlet pipe, the ash discharge speed can be improved. By using the connecting mechanism, the connecting head is clamped into the connecting piece, and by turning the rotating handles on both sides, the threaded rod can be driven to rotate. While the threaded rod rotates, the clamping block can be driven to slide in the chute and make the clamping block snap into the installation groove to fixedly connect the connecting piece and the connecting head. At the same time, the sealing ring can squeeze the gasket inside the sealing groove to improve the sealing performance between the connecting piece and the connecting head, reducing the connection time and ash leakage phenomenon.
