Abstract
Description
Technical Field
[0001] This utility model relates to the steel industry, and more specifically to an improved chute. Background Technology
[0002] A chute is a trough on the ground that transports goods from a high place to a low place. It has a smooth inner surface and allows goods to slide down automatically. Belt conveyors are often used to transport raw materials to the chute at a high position, and then the materials are transported to the place where they are to be used for relevant processing.
[0003] Currently, the chutes used in steel plants are usually set up in workshops at higher locations. The material is fed into the chute cavity by inserting the discharge end of the belt conveyor into the chute shell and then sliding through the chute to the location where the material needs to be used.
[0004] In the sintering workshop, the blended ore used in the sintering machine is transported to the chute above the sintering machine via a belt conveyor. The raw material is then sent to the silo through the chute. Because the blended ore contains large, uneven pieces, these large pieces often cause chute blockage and equipment malfunctions such as jamming of the batching disc feeder during the process of entering the sintering silo. This seriously affects the stability of the sintering process. Therefore, it is necessary to improve the chute to avoid large pieces of material blocking the chute and affecting subsequent processes. Utility Model Content
[0005] This utility model provides an improved chute. By setting up a grate to block large pieces of material in the incoming material, small pieces of material fall into the chute through the gaps in the grate, while large pieces of material are guided into the distribution bin from the grate. In order to avoid large pieces of material being inserted into the gaps in the grate and causing blockage, a comb tooth is set to rotate, thereby scraping the material out of the gaps in the grate and into the distribution bin.
[0006] This utility model is achieved through the following technical solution:
[0007] An improved chute includes,
[0008] A chute, the chute comprising a shell, the upper part of which is provided with a negative pressure air duct;
[0009] A belt conveyor is located behind the chute, and its discharge end is located inside the housing;
[0010] The material distribution bin is located in front of the chute. A material distribution hopper is provided between the material distribution bin and the belt conveyor. A grate is fixedly connected to one end of the material distribution hopper near the belt conveyor. Rotating comb teeth are provided above the grate to scrape large pieces of material from above the grate into the material distribution bin.
[0011] Furthermore, the comb teeth are provided in multiple ways and fixed on a rotating shaft, which is rotatably connected to one end of the housing and extends out of the housing and is fixedly connected to the output end of the drive motor.
[0012] Furthermore, the thickness of the comb teeth is less than the grid gap of the comb, and the width of the comb teeth gradually decreases from the connection point with the rotating shaft to its free end.
[0013] Furthermore, a closed door is hinged and fixed to the outer edge of the housing.
[0014] Furthermore, the material distribution hopper is provided with a ramp, and the grate is fixedly connected to the upper end of the ramp.
[0015] Furthermore, baffles are fixedly connected to both sides of the slope, and the upper end of the baffles is connected by a connecting rod.
[0016] Furthermore, the width of the lower end of the slope gradually decreases until it connects to the upper end of the distribution hopper.
[0017] Furthermore, a vibration motor is provided outside the housing.
[0018] The beneficial effects of this utility model are as follows:
[0019] By setting up grates, excessively large materials introduced into the chute by the belt conveyor are guided from the chute into the distribution bin. At the same time, in order to prevent large pieces of material from getting stuck in the gaps of the grates, rotating comb teeth are set up to break up or scrape out large pieces of material stuck in the gaps of the grates.
[0020] By setting the thickness of the comb teeth to be smaller than the grid gaps, the rotating comb teeth can scrape out the material stuck in the grid gaps and guide it into the distribution bin.
[0021] By setting up a sealed door, the negative pressure pipe's ability to absorb dust is improved.
[0022] By setting up ramps to guide the flow of materials, it is possible to prevent materials from spilling between the distribution bins and chutes.
[0023] The overall strength of the slope is ensured by installing connecting rods.
[0024] By gradually reducing the width of the lower end of the ramp, the width of the distribution hopper can be effectively reduced.
[0025] By installing a vibrating motor, the rolling speed of materials down the slope is increased, thus preventing siltation. Attached Figure Description

[0027] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0029] like Figure 1 As shown, an improved chute includes,
[0030] The chute 10 includes a housing 101, and a negative pressure air duct 102 is provided on the upper part of the housing 101.
[0031] The belt conveyor 20 is located behind the chute 10, and its discharge end is located inside the housing 101.
[0032] The material distribution bin 30 is located in front of the chute 10. A material distribution hopper 301 is provided between the material distribution bin 30 and the belt conveyor 20. A grate 3011 is fixedly connected to one end of the material distribution hopper 301 near the belt conveyor 20. Rotating comb teeth 3012 are provided above the grate 3011 to scrape large pieces of material from above the grate 3011 into the material distribution bin 30.
[0033] Specifically, by setting up a grate 3011, large pieces of material introduced into the chute by the belt conveyor are directed into the distribution bin. At the same time, by setting up comb teeth, the material stuck in the grate 3011 is scraped out. This can effectively prevent large pieces of material from clogging and affecting the material discharge effect.
[0034] Furthermore, the comb teeth 3012 are provided in multiple quantities and fixed on the rotating shaft 3013. The rotating shaft 3013 is rotatably connected to the housing 101, and one end of the shaft extends out of the housing 101 and is fixedly connected to the output end of the drive motor 3014.
[0035] Specifically, the drive motor 3014 drives the rotating shaft 3013 to rotate, and the rotating shaft 3013 drives the comb teeth to rotate, inserting them into the grid of the grate 3011 to scrape out the material.
[0036] Furthermore, in order to better scrape out the material, the thickness of the comb teeth 3012 is smaller than the grid gap of the grate 3011, and the width of the comb teeth 3012 gradually decreases from the connection with the rotating shaft 3013 to its free end, which can reduce the overall weight of the comb teeth 3012.
[0037] Furthermore, in order to improve the dust absorption effect of the negative pressure air duct, a closed door 1011 is hinged and fixed to the outer edge of the outer shell 101.
[0038] Furthermore, to prevent material from falling when it is introduced into the distribution hopper 301, the distribution hopper 301 is provided with a ramp 3015, and the grate 3011 is fixedly connected to the upper end of the ramp 3015.
[0039] Furthermore, to prevent materials from falling from one side of the ramp 3015, baffles 30151 are fixedly connected to both sides of the ramp 3015, and the upper end of the baffles 30151 is connected by a connecting rod 30152.
[0040] Furthermore, the width of the lower end of the ramp 3015 gradually decreases until it connects to the upper end of the distribution hopper 301.
[0041] Furthermore, in order to improve the material sliding ability and avoid accumulation, a vibration motor 40 is provided on the outside of the housing 101.
[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
