Description

Technical Field

[0001] This utility model relates to a fly ash feeding device for a dual-shaft mixer for hazardous waste feeding. Background Technology

[0002] With industrial development, the amount of hazardous waste emitted during industrial production processes is increasing. For environmental protection and health reasons, hazardous waste treatment is necessary. Some hazardous waste, after combustion, produces fly ash, which is then transported and dumped into hazardous waste treatment systems. Currently, fly ash is transported by dumping bags of fly ash into a screw feeder, which then conveys it to a belt conveyor. The belt conveyor then tilts the fly ash upwards to a twin-shaft mixer for mixing. However, the process of dumping bags of fly ash into hoppers equipped with screw feeders typically involves manual handling, cutting open the bags with a knife, and then dumping the fly ash from the ton bags into the screw feeder. This method is cumbersome, time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] This invention addresses the aforementioned problem by providing a fly ash feeding device for a hazardous waste twin-shaft mixer that is convenient and efficient to use.

[0004] This utility model is constructed as follows: it includes a feeding hopper and a movable hoisting mechanism disposed above the feeding hopper. The opening of the feeding hopper is provided with multiple support rods spaced apart for placing the bag body. Between the two middle support rods, there is a cutting component for cutting the bottom of the bag body, so as to facilitate the fly ash in the bag body to fall into the feeding hopper.

[0005] Furthermore, the cutting assembly includes a guide rod and a guide block sleeved on the guide rod. The guide block can move along the guide rod. A fixed seat is provided above the guide block, and a cutting blade is fixed on the fixed seat. The upper end of the cutting blade is slightly higher than the upper end of the support rod.

[0006] Furthermore, the fixed seat and guide block are driven by a driving device to move along the guide rod; the driving device is an electric cylinder, and a mounting bracket is provided on the outside of the feed hopper, with the electric cylinder mounted on the mounting bracket.

[0007] Furthermore, the feed hopper has a funnel-shaped cross-section, and a vibration motor is installed on the side of the feed hopper.

[0008] Furthermore, the feed hopper is provided with side baffles, rear plates and top plates on both sides, rear and top respectively. The two side baffles, rear plates and top plates are integrated and form a cover. An avoidance groove is provided in the middle of the top plate to avoid the hoisting mechanism.

[0009] Furthermore, a spiral feeding mechanism is provided at the bottom of the feeding hopper, with a feeding port above the spiral feeding mechanism and a discharge port on one side of the bottom of the feeding hopper.

[0010] Furthermore, the hoisting mechanism includes an I-beam and an electric hoist. The electric hoist has a fixed plate on both sides above it, and a movable wheel is provided on the inner side of the fixed plate. The I-beam has a movable groove on both sides, and the movable wheel can move along the movable groove. The telescopic end of the electric hoist is provided with a winding rope, and a hook is fixed on the winding rope.

[0011] Furthermore, a suction pipe is provided on the rear panel, and the suction end of the suction pipe is provided with a protective cover with suction holes.

[0012] Furthermore, the upper inner walls of the feed hopper are provided with fixing blocks, and the fixing blocks are provided with fixing grooves. The two ends of the support rod are respectively placed in the fixing grooves on the corresponding sides. The outer side of the fixing blocks is provided with positioning components for penetrating the fixing blocks and the support rods.

[0013] Furthermore, a conveying mechanism is provided in front of the feeding hopper.

[0014] Compared with the prior art, this utility model has the following advantages: The device has a simple structure and reasonable design, requires no multiple people to cooperate in unloading, saves time and labor, is easy to use, and greatly improves work efficiency. The conveying mechanism transports the ton bag filled with fly ash to the front of the feeding hopper. The hook of the hoisting mechanism hooks the bag handle, and the electric hoist of the hoisting mechanism lifts the ton bag onto the support rod of the feeding hopper. Then, the drive device of the cutting component drives the cutting blade to move along the guide rod. The cutting blade cuts a large opening at the bottom of the ton bag, at which point the fly ash inside the ton bag falls into the feeding hopper. It is then output from the outlet of the feeding hopper through the spiral feeding mechanism inside the feeding hopper. Under the conveying of another conveying mechanism, it enters the twin-shaft mixer for subsequent mixing and processing. During the unloading process of the ton bag, because the fly ash accumulates in the feeding hopper, the hoisting mechanism lifts the ton bag upwards to facilitate the better and complete unloading of the material inside the ton bag.
