Description

Technical Field

[0001] This application relates to the technical field of steel slag unloading equipment, and in particular to a negative pressure transport and unloading device for steel slag. Background Technology

[0002] In the steel smelting industry, steel slag, as a major byproduct of the steelmaking process, is crucial for energy conservation, emission reduction, and resource recycling through efficient handling and transportation. Statistics show that approximately 150-300 kg of steel slag is generated for every ton of steel produced. Improper handling not only occupies significant land resources but also causes environmental pollution and resource waste. Currently, steel slag transportation mainly relies on traditional methods such as grab bucket cranes and dump trucks, but these methods have numerous drawbacks.

[0003] In practical use, it was found that some simple negative pressure transport devices lack an effective pretreatment mechanism, and the agglomeration of steel slag due to high temperature cooling cannot be resolved, resulting in frequent blockage of the transport pipeline and long downtime for equipment maintenance. Moreover, the unloading pipe of most devices is prone to blockage during discharge, requiring manual cleaning, which not only increases labor costs but also poses safety hazards. Therefore, we proposed a steel slag negative pressure transport unloading device to solve the above problems. Utility Model Content

[0004] The purpose of this application is to provide a negative pressure transport and unloading device for steel slag, which can effectively prevent blockage of the transport pipeline and the unloading pipeline.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: a negative pressure transport and unloading device for steel slag, comprising a slag tank, a hopper fixedly installed at the bottom of the slag tank, a first fixed frame provided on the outside of the slag tank, a fixed ring fixedly installed at the top of the first fixed frame, the fixed ring being fixedly sleeved on the outside of the slag tank, a functional box fixedly installed on the right side of the first fixed frame, a motor fixedly installed on the right side of the functional box, second fixed frames fixedly installed on both inner walls of the slag tank, and a common mounting shell fixedly installed between the two second fixed frames; an agitation mechanism is provided between the mounting shell and the hopper, a vacuum pump is fixedly installed at the bottom of the functional box, a negative pressure transport mechanism is provided between the vacuum pump and the hopper, and a reciprocating mechanism is provided inside the functional box.

[0006] A further configuration of this application is: the agitation mechanism includes an agitation shaft and an agitation rod, the agitation shaft is rotatably mounted on the inner wall of the top of the mounting shell, the bottom end of the agitation shaft extends into the hopper, and an agitation rod is provided on the agitation shaft, the agitation rod being located inside the hopper.

[0007] By adopting the above technical solution and setting up an agitation mechanism, the agitation shaft can drive the agitation rod to rotate, which can fully crush and disperse the steel slag discharged from the slag pot through the feed hopper. This can break up the clumps of steel slag into more easily transportable granular form, greatly reducing the risk of clogging in the feed hopper.

[0008] A further configuration of this application is as follows: the reciprocating mechanism includes a reciprocating lead screw and a nut seat. The reciprocating lead screw is fixedly installed on the motor output shaft. The left end of the reciprocating lead screw extends into the mounting housing. A nut seat is sleeved on the reciprocating lead screw. The bottom of the nut seat extends to the bottom of the function box. A gear mechanism is provided between the reciprocating lead screw and the agitator shaft. A dredging mechanism is provided on the left side of the nut seat.

[0009] By adopting the above technical solution and by setting up a reciprocating mechanism, the reciprocating screw can drive the nut seat to move back and forth, thereby achieving the purpose of driving the unblocking mechanism to move back and forth.

[0010] A further feature of this application is that the gear mechanism includes two bevel gears, and bevel gears are fixedly sleeved on both the left end of the reciprocating screw and the agitator shaft. The bevel gears are located inside the mounting housing, and the two bevel gears mesh with each other.

[0011] By adopting the above technical solution and by setting up a gear mechanism, the reciprocating screw can drive the agitator shaft to rotate synchronously.

[0012] A further configuration of this application is as follows: the negative pressure transport mechanism includes a suction pipe, a conveying pipe and a discharge pipe, a suction pipe is provided between the vacuum pump and the hopper, a conveying pipe is provided on the right side of the vacuum pump, and a discharge pipe is provided at the bottom of the conveying pipe.

[0013] By adopting the above technical solution and setting up a negative pressure conveying mechanism, the vacuum pump can quickly draw air through the suction pipe, and a negative pressure environment can be quickly formed in the hopper and the suction pipe, which can suck the steel slag into the suction pipe and transport it to the unloading pipe for unloading.

[0014] A further configuration of this application is as follows: the unblocking mechanism includes a slide rod and a lever plate, the slide rod is fixedly installed on the left side of the nut seat, the left end of the slide rod extends into the unloading pipe, and the lever plate is fixedly installed on the top of the slide rod, with the lever plate located inside the unloading pipe.

[0015] By adopting the above technical solution and setting up a dredging mechanism, the nut seat can drive the dial plate to reciprocate synchronously in the unloading pipe through the slide rod. This enables the dial plate to forcibly dredge the blocked steel slag, disperse the accumulated steel slag, and ensure the unobstructed flow of the unloading pipe.

[0016] A further feature of this application is that a control module is provided on the front side of the functional box, and the control module is electrically connected to the motor and the vacuum pump.

[0017] By adopting the above technical solution and by setting up a control module, the motor and vacuum pump can be precisely controlled.

[0018] A further feature of this application is that the same fixing rod is fixedly installed on the inner walls of both sides of the functional box, the fixing rod is located below the reciprocating lead screw, and the nut seat is slidably sleeved on the fixing rod.

[0019] By adopting the above technical solution and by setting a fixing rod, the nut seat can move more smoothly when moving left and right.

[0020] A further feature of this application is that the top of the mounting shell has an arc-shaped design.

[0021] By adopting the above technical solution and by setting up an installation shell, the gear mechanism can be protected by the installation shell, and the arc-shaped design at the top of the installation shell can prevent steel slag from accumulating on the top of the installation shell.

[0022] A further feature of this application is that a seat hole is provided at the bottom of the functional box, and the nut seat is slidably connected to the seat hole.

[0023] By adopting the above technical solution, and by providing a seat hole, a travel path for the nut seat can be provided through the seat hole.

[0024] The beneficial effects of this application are:

[0025] Through the cooperation of the motor, reciprocating lead screw, bevel gear, agitator shaft and agitator rod, the motor drives the agitator shaft to rotate, which enables the steel slag discharged from the slag pot through the hopper via the agitator rod to be fully crushed and dispersed. This breaks up the clumps of steel slag into more easily transportable granular form, greatly reducing the risk of hopper blockage and creating conditions for the steel slag to enter the extraction pipe smoothly, thus ensuring the continuity of negative pressure transportation.

[0026] By coordinating the reciprocating screw, nut seat, slide bar, and dial plate, the reciprocating screw drives the slide bar to move back and forth, and the dial plate can forcefully clear the blocked steel slag by moving left and right. This disperses the accumulated steel slag, ensuring unobstructed discharge pipes and preventing equipment downtime due to blockages, thus significantly improving the stability and reliability of the equipment operation.

[0035] Specifically, the agitation mechanism includes an agitation shaft 402 and an agitation rod 403. The agitation shaft 402 is rotatably mounted on the inner wall of the top of the mounting housing 401. The bottom end of the agitation shaft 402 extends into the hopper 101. The agitation rod 403 is provided on the agitation shaft 402 and is located inside the hopper 101.

[0036] Specifically, the reciprocating mechanism includes a reciprocating lead screw 302 and a nut seat 303. The reciprocating lead screw 302 is fixedly installed on the output shaft of the motor 301. The left end of the reciprocating lead screw 302 extends into the mounting housing 401. The nut seat 303 is sleeved on the reciprocating lead screw 302. The bottom of the nut seat 303 extends to the bottom of the function box 3. A gear mechanism is provided between the reciprocating lead screw 302 and the agitator shaft 402. A dredging mechanism is provided on the left side of the nut seat 303.

[0037] Specifically, the gear mechanism includes two bevel gears 8. The left end of the reciprocating screw 302 and the stirring shaft 402 are both fixedly fitted with bevel gears 8. The bevel gears 8 are located inside the mounting housing 401, and the two bevel gears 8 mesh with each other.

[0038] Specifically, the negative pressure transport mechanism includes a suction pipe 501, a conveying pipe 502 and a discharge pipe 6. The vacuum pump 5 and the hopper 101 are connected by the same suction pipe 501. The conveying pipe 502 is located on the right side of the vacuum pump 5, and the discharge pipe 6 is located at the bottom of the conveying pipe 502.

[0039] Specifically, the unblocking mechanism includes a slide rod 601 and a lever 602. The slide rod 601 is fixedly installed on the left side of the nut seat 303. The left end of the slide rod 601 extends into the unloading pipe 6. The lever 602 is fixedly installed on the top of the slide rod 601 and is located inside the unloading pipe 6.

[0040] Specifically, a control module 7 is provided on the front side of the function box 3, and the control module 7 is electrically connected to the motor 301 and the vacuum pump 5.

[0041] Specifically, the same fixing rod is fixedly installed on the inner walls of both sides of the function box 3. The fixing rod is located below the reciprocating lead screw 302, and the nut seat 303 is slidably sleeved on the fixing rod.

[0042] Specifically, the top of the mounting housing 401 has an arc-shaped design.

[0043] Specifically, the bottom of the function box 3 has a seat hole, and the nut seat 303 is slidably connected to the seat hole.

[0044] In this application, during operation, the operator first starts the control module 7, and the motor 301 and vacuum pump 5 are turned on synchronously, and the device enters the operating state. The motor 301, as the power core, drives the reciprocating screw 302 to rotate at high speed through its output shaft. Under the dual constraint of the reciprocating screw 302 and the fixed rod, the nut seat 303 performs precise reciprocating linear motion along the reciprocating screw 302, providing the power foundation for the coordinated operation of the multiple stages of the entire device. In the slag pretreatment stage, the bevel gear 8 at the left end of the reciprocating screw 302 and the bevel gear 8 on the stirring shaft 402 mesh tightly, enabling the rotation of the motor 301... Power is transmitted to the stirring shaft 402, which in turn drives the stirring rod 403 to rotate continuously within the hopper 101. During the steelmaking process, steel slag is prone to agglomeration and adhesion due to high-temperature cooling, which can seriously affect subsequent transportation efficiency and even cause pipeline blockage. The rotation of the stirring rod 403 can fully crush and disperse the steel slag discharged from the slag pot 1 through the hopper 101, breaking the agglomerated steel slag into more easily transportable granular form, greatly reducing the risk of blockage in the hopper 101, creating conditions for the steel slag to smoothly enter the extraction pipe 501, and ensuring the continuity of negative pressure transportation.

[0045] In the negative pressure transportation process, the vacuum pump 5 quickly extracts air through the extraction pipe 501, rapidly creating a negative pressure environment in the hopper 101 and the extraction pipe 501. The steel slag, pretreated by the stirring rod 403, is quickly and orderly sucked into the extraction pipe 501 under the action of negative pressure suction, and then transported to the unloading pipe 6 through the conveying pipe 502 for unloading. This achieves the purpose of efficient transportation of steel slag.

[0046] In the unloading process, when steel slag becomes blocked in the unloading pipe 6 due to uneven particle size or excessive accumulation, the sliding rod 601 fixed on the left side of the nut seat 303 will drive the dial plate 602 to reciprocate synchronously in the unloading pipe 6. The dial plate 602 can forcefully clear the blocked steel slag by moving left and right, thereby dispersing the accumulated steel slag and ensuring that the unloading pipe 6 is unobstructed. This will prevent equipment downtime caused by blockage and significantly improve the stability and reliability of the device operation.
