Description

Technical Field

[0001] This utility model relates to a novel belt conveyor environmentally friendly material guide chute device, belonging to the technical field of blast furnace equipment in the metallurgical industry. Background Technology

[0002] In the blast furnace workshop of the ironmaking plant, the guide troughs above the main charging conveyor belt are generally vertical funnel structures. The upper part of the existing guide troughs connects to the blast furnace workshop's discharge port, while the lower part connects directly to the main charging conveyor belt, directly conveying materials to it. During charging, the tail end of the main charging conveyor belt produces significant dust, failing to meet environmental protection requirements. Furthermore, severe material spillage occurs during sintering and pelletizing, causing considerable damage to the tail rollers of the main charging conveyor belt. The cast ceramic coating on the rollers essentially falls off within a month, resulting in the tail rollers being worn and requiring replacement in less than a month, increasing equipment costs. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of environmentally friendly conveyor belt chute device to solve the problems of environmental protection and short service life of the tail roller of the feeding conveyor belt in blast furnace production, eliminate potential equipment accidents, improve the on-site environment, save spare parts costs, and solve the above-mentioned problems in the background technology.

[0004] The technical solution of this utility model is: A novel belt conveyor environmentally friendly material guiding chute device includes a vertical material guiding chute, an inclined material guiding chute, a C-shaped dust collector, a main charging belt conveyor, and wear-resistant baffle plates. The upper end of the vertical material guiding chute is connected to the discharge port of the blast furnace workshop, and the lower end of the vertical material guiding chute is connected to the upper end of the inclined material guiding chute. The lower end of the inclined material guiding chute is connected to the top of the C-shaped dust collector. The C-shaped dust collector is fixed on the main charging belt conveyor, and the tail end of the C-shaped dust collector extends towards the tail of the main charging belt conveyor and connects to the dust removal pipe. The inclined material guiding chute has multiple layers of wear-resistant baffle plates arranged at intervals from top to bottom. Each layer of wear-resistant baffle plates consists of three plates, which are fixed on the front, left, and right inner walls of the inclined material guiding chute, forming a three-sided baffle structure.

[0005] Furthermore, the angle between the inclined guide chute and the main feeding belt is 30°.

[0006] Furthermore, the upper end of the vertical guide chute is connected to the discharge port of the blast furnace workshop via flange one, and flange two at the lower end of the vertical guide chute is connected to flange three at the upper end of the inclined guide chute via flange bolts.

[0007] Furthermore, the upper end of the flange two is provided with connecting lug one on both the front and rear sides, and the connecting lug one is connected to the connecting lug two on the frame beam in the blast furnace workshop by steel wire rope.

[0008] Furthermore, multiple reinforcing ribs are provided between the upper outer wall of the inclined guide trough and the lower end face of the flange three.

[0009] The positive effects of this utility model are as follows: The inclined guide chute and the wear-resistant baffle plate can effectively buffer the material speed and amount, solve the serious problem of material spillage, reduce the wear of the belt conveyor on the tail roller, eliminate potential equipment accidents, and save spare parts costs; at the same time, the addition of a C-type dust hood and its connection with the dust removal pipeline provides good dust removal effect, improves the on-site environment, reduces the labor intensity of employees, and makes the on-site environment cleaner and tidier.

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments: A novel belt conveyor environmentally friendly material guide chute device includes a vertical material guide chute 1, an inclined material guide chute 2, a C-shaped dust collector hood 11, a main feeding belt conveyor 12, and wear-resistant baffle plates 13. The upper end of the vertical material guide chute 1 is connected to the discharge port of the blast furnace workshop, and the lower end of the vertical material guide chute 1 is connected to the upper end of the inclined material guide chute 2. The lower end of the inclined material guide chute 2 is connected to the top of the C-shaped dust collector hood 11. The C-shaped dust collector hood 11 is fixed on the main feeding belt conveyor 12, and the tail end of the C-shaped dust collector hood 11 extends towards the tail of the main feeding belt conveyor 12 and connects to the dust removal pipe. The inclined material guide chute 2 has multiple layers of wear-resistant baffle plates 13 arranged at intervals from top to bottom. Each layer of wear-resistant baffle plates 13 consists of three plates, which are fixed on the front, left, and right inner walls of the inclined material guide chute 2, forming a three-sided baffle structure.

[0012] The angle between the inclined guide chute 2 and the main feeding belt 12 is 30°. Preferably, the inclined guide chute 2 is spliced ​​from Q235B steel plates and welded with E43 welding rods using continuous weld seams. After installation, the inclined angle forms a 30° angle with the belt, which ensures the stability of material feeding while taking into account the belt feeding capacity to prevent material accumulation and scattering, and increases the service life of the tail roller of the belt conveyor.

[0013] The upper end of the vertical guide chute 1 is connected to the discharge port of the blast furnace workshop through flange 1 3, and the flange 2 4 at the lower end of the vertical guide chute 1 is connected to the flange 3 5 at the upper end of the inclined guide chute 2 through flange bolts 6.

[0014] The upper end of flange 2 4 is provided with connecting lug 1 7 on both the front and rear sides. Connecting lug 1 7 is connected to connecting lug 2 8 on the frame beam 10 in the blast furnace workshop by steel wire rope, thereby increasing the connection strength between the vertical guide chute 1 and the inclined guide chute 2.

[0015] The upper outer wall of the inclined guide trough 2 is provided with multiple reinforcing ribs 9 between the lower end face of the flange 3 5 to increase the connection strength.

[0016] See attached document Figure 1-3 In this embodiment, the original straight-through guide chute is cut off from the middle, making the distance from the upper surface of the belt to the cut-off part 1500mm. Then, the diameter of the straight-through guide chute is measured and flange 24 is made to form a vertical guide chute 1. In this embodiment, based on the material quantity and speed on site, it is calculated that the inclined guide chute 2 needs to be installed at an angle of 30° with the belt to adjust the feeding speed. Multiple layers of baffle wear-resistant plates 13 are arranged on the inner wall of the inclined guide chute 2 from top to bottom at 100mm intervals. The baffle wear-resistant plates 13 are inclined upward and have a width of 200mm. The baffle wear-resistant plates 13 are made of Q345B wear-resistant manganese steel plate. The purpose is to reduce the wear of sintered ore and coke on the inside of the guide chute during production. The material is stored inside the guide chute for abrasive use, which effectively extends the service life of the guide chute and the tail roller of the main feeding belt. Meanwhile, to mitigate the significant dust pollution during material unloading, a C-shaped dust collector hood is installed at the outlet of the inclined material guide chute 2. This hood extends 1.5 meters towards the tail of the main feeding conveyor belt and connects to the existing dust collection pipe, increasing the suction area and preventing dust spillage. This reduces cleaning time for staff, lowers labor intensity, and creates a cleaner, tidier, and more orderly work environment. This invention features simple processing, low cost, easy maintenance and operation, and high stability.
