Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a cleaning device for a sintering trolley. Background Technology

[0002] In the iron and steel smelting industry, the ore entering the blast furnace generally needs to undergo sintering. The sintering trolley is a key piece of equipment in the sintering process of smelting ore. The sintering trolley grate is composed of many rectangular cast iron materials arranged in a row. It is installed at the bottom of the trolley to support the sintering material for sintering. There are certain gaps between each grate for ventilation, which is beneficial for exhaust and combustion during the sintering process. When the mineral is burned, the gaps between the grate can easily become blocked, resulting in severe grate blockage, poor air permeability, increased negative pressure, serious safety hazards to the equipment, and affecting the quality and output of sinter.

[0003] In existing technologies, two main solutions are used to address the problem of grate bar clogging: manual vibration cleaning and mechanical vibration cleaning. Manual vibration cleaning is labor-intensive and inefficient. Mechanical vibration cleaning is highly destructive to the grate bars and lacks an effective way to determine the extent of clogging and adjust the vibration frequency accordingly. If a machine vision system is installed to determine the extent of clogging, it is not only costly, but the camera and other system components are also difficult to operate stably in harsh working environments with high temperatures and dust.

[0004] Therefore, there is a need for a sintering trolley cleaning device that minimizes damage to the grate bars while ensuring the rapping effect, and that can effectively identify local blockages and flexibly adjust the rapping frequency. Summary of the Invention

[0005] This application provides a sintering trolley cleaning device, which solves the problems of high labor intensity and low work efficiency in the prior art when manually vibrating to clean the sintering trolley grate bars, and the technical problems of large damage to the grate bars and inability to reliably and effectively determine the local blockage and flexibly adjust the vibration frequency when mechanically vibrating to clean the trolley grate bars. The device achieves the technical effect of minimizing damage to the grate bars while ensuring the vibration effect, and effectively determining the local blockage and flexibly adjusting the vibration frequency.

[0006] This application provides a sintering trolley cleaning device, which is installed below the sintering trolley and is used to clean the grate bars of the sintering trolley.

The contact arc plate is an arc-shaped curved plate with its opening facing downwards. Its width direction is perpendicular to the length direction of the swing arm and it is fixed to the top of the vertical plate.

[0008] Furthermore, the jet feedback assembly includes a top jet block, a connecting plate, a vertical compression spring, a bottom load frame, a constant pressure gas delivery assembly, and a detection assembly; The top jet block is a hollow block with densely packed jet holes on the top. The internal space is connected to the constant pressure gas delivery assembly through a pipe. The distance between the top surface and the grate bar is less than 5 centimeters. The jet hole is a through hole; The connecting plate is a rigid plate and is fixed to the bottom of the top jet block; The bottom load frame is a vertical hollow column frame, positioned on the ground and directly below the top jet block; The vertical compression spring is a metal compression spring, which is set vertically.

The constant pressure gas delivery assembly is used to deliver gas at a stable pressure into the top jet block and to eject the gas from the top jet block. The detection components include a pressure sensor and / or a length sensor; The pressure sensor is positioned between the top jet block and the connecting plate and is connected to the control unit to measure the downward pressure force when the top jet block sprays air. The length sensor is positioned on the vertical compression spring and is used to measure the real-time length of the vertical compression spring.

[0009] Preferably, multiple jet feedback components work together to perform zoned detection on the moving grate bars; each swing arm is driven by an independent dial shaft; during cleaning, some or all of the vibrating heads are controlled to operate for cleaning as needed.

[0010] Furthermore, the top of the top jet block is sharp.

[0013] Preferably, the jet feedback component is positioned close to the vibrating sweeper, and by observing the change in the detected impact force, it can be determined whether debris has been shaken off and the amount of debris shaken off.

[0014] Preferably, it also includes a weighing component; The receiving and weighing component is located directly below the vibrating sweeper and is used to weigh the amount of debris accumulated in a portion of the area directly below the grate bar per unit time to quantify the cleaning effect. The weighing assembly includes a base positioned on the ground, a rotating frame, a top-supporting container, and a weighing module. The rotating frame is a rigid support that is rotatably connected to the base around an axis parallel to the ground and rotates in a controlled manner. The top support container is a plate-shaped container with an open top, positioned on top of the rotating frame; the weighing module is used to weigh the weight of the object carried in the top support container and is positioned between the top support container and the rotating frame.

An air jet feedback component is installed, which measures the reaction force received when it sprays air upwards to indicate the clogging status of the grate bars. This effectively solves the problems of high labor intensity and low efficiency in manual rapping for cleaning sintering trolley grate bars, and the significant damage to the grate bars and inability to reliably and effectively determine local clogging and flexibly adjust the rapping frequency when using mechanical rapping. Therefore, the sintering trolley cleaning device achieves the technical effect of minimizing damage to the grate bars while ensuring rapping effectiveness, and effectively determining local clogging and flexibly adjusting the rapping frequency.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figures 1 to 4 As shown, the sintering trolley cleaning device of this application is located below the sintering trolley and is used to clean the grate bars 001 of the sintering trolley. It includes a vibratory cleaner 100, an air jet feedback assembly 300, a power assembly, and a control unit.

[0023] like Figure 1 and Figure 2 As shown, the vibratory sweeper 100 includes a swing arm bracket 110, a swing arm 120, a vibratory head 130, a dial wheel 140, and a dial wheel shaft 150 positioned on the ground; The swing arm bracket 110 is a rigid frame that serves as a load-bearing and support structure. The swing arm 120 is a horizontally placed rigid rod with a U-shaped longitudinal section. It is rotatably connected to the swing arm bracket 110 near the middle position. The axis of rotation is parallel to the horizontal ground, which plays the role of transmitting force. The vibrating head 130 is fixed to one end of the top surface of the swing arm 120, is made of metal, and is used to strike the grate bar 001. The vibrating head 130 includes a vertical plate and a contact arc plate.

The contact arc plate is an arc-shaped curved plate with its opening facing downwards, and its width direction is perpendicular to the length direction of the swing arm 120. It is fixed to the top of the vertical plate. When the vibrating head 130 moves upwards under the drive of the swing arm 120 to strike the grate bar 001, the outer convex surface of the contact arc plate directly contacts the grate bar 001. Because the contact surface is arc-shaped, the damage to the grate bar 001 is minimal. A counterweight 121 is fixed on the side wall of the swing arm 120 away from the vibrating head 130; the counterweight 121 is a hard block or plate and serves as a counterweight. The swing arms 120 with the positioning vibrating head 130 are arranged in a row below the grate bar 001, with a number greater than 5; The dial shaft 150 is positioned on the ground by a rigid bracket and rotates around its own axis under the coordinated control of the power component and the control unit. The dial 140 is a cam or other irregularly shaped wheel, positioned on the dial shaft 150 and arranged in a row, corresponding one-to-one with the swing arm 120. When the dial shaft 150 rotates, it drives the dial 140 to rotate. During the rotation of the dial 140, a force is applied to the swing arm 120 in a regular manner, causing it to swing frequently, thereby prompting the vibrating head 130 to knock and clean the grate bar 001, knocking and vibrating the debris on the grate bar 001 to be removed.

[0024] like Figure 3 and Figure 4 As shown, the jet feedback component 300 is used to react to the clogging of the grate bar 001 by measuring the reaction force of its own upward jet. It is positioned on one side of the vibratory cleaner 100, and there are more than 5 of them. They are arranged in a row close together along the width of the trolley. The grate bar 001 to be cleaned first moves over the jet feedback component 300 and then moves to the vibratory cleaner 100. The jet feedback assembly 300 includes a top jet block 310, a connecting plate 320, a vertical compression spring 330, a bottom load frame 340, a constant pressure air delivery assembly 350, and a detection assembly 321; The top air jet block 310 is a hollow block with densely packed air jet holes 311 on the top. The internal space is connected to the constant pressure air delivery assembly 350 through a pipe. The distance between the top surface and the grate bar 001 is less than 5 cm. The air jet holes 311 are through holes. The connecting plate 320 is a rigid plate and is fixed to the bottom of the top jet block 310; The bottom support frame 340 is a vertical hollow column frame, positioned on the ground and directly below the top air jet block 310, serving as a load-bearing and supporting element; The vertical compression spring 330 is a metal compression spring, which is vertically arranged. Its top is fixed to the bottom of the connecting plate 320 and its bottom is fixed to the top of the base frame 340. It retracts when compressed. The constant pressure gas delivery assembly 350 is used to deliver gas at a stable pressure into the top jet block 310 and to eject the gas from the top jet block 310. Its main structure is an air pump. The detection component 321 includes a pressure sensor and / or a length sensor; The pressure sensor is positioned between the top jet block 310 and the connecting plate 320 and is connected to the control unit for measuring the downward pressure force when the top jet block 310 jets. The length sensor is positioned on the vertical compression spring 330 and is used to measure the real-time length of the vertical compression spring 330.

[0025] The power component is used to provide power for the operation of each component of the sintering trolley cleaning device of this application. The control unit plays the role of controlling the coordinated operation of each component of the sintering trolley cleaning device. Both are existing technologies and will not be described in detail here. The control unit is connected to the display signal, and the display shows the data measured by the detection component 321 in real time.

[0026] Preferably, the control unit is a combination of a programmable logic controller and control buttons.

[0027] During the movement of the grate bars 001 of the sintering trolley, the constant pressure air supply component 350 operates continuously, and the top air jet block 310 continuously jets air upwards to clean the grate bars 001. During the jetting process of the top air jet block 310, the blockage of the grate bars 001 will hinder the gas flow, thereby causing the top air jet block 310 to move downwards under the reaction force. The detection component 321 directly or indirectly measures the force condition of the top air jet block 310 (quantifies the force condition), feeds it back to the operator, and the operator adjusts the operating frequency of the vibrating cleaner 100, or directly transmits it to the control unit, which then controls the vibrating cleaner 100 to operate at a specific frequency, thereby ensuring the cleaning effect.

[0028] Multiple jet feedback components 300 can work together to perform zoned detection of moving grate bars 001; preferably, each swing arm 120 is driven by an independent dial shaft 150; during cleaning, some or all of the vibrating heads 130 can be controlled to operate for cleaning as needed.

[0029] Preferably, the vertical compression spring 330 is fitted with a non-metallic sheath.

[0030] Furthermore, the pipeline connecting the constant pressure gas delivery component 350 and the top jet block 310 includes a connecting rigid pipe 312 and a connecting flexible pipe 313; the connecting rigid pipe 312 is a rigid pipe body, with its top positioned on the top jet block 310 and its bottom connected to the connecting flexible pipe 313; the connecting flexible pipe 313 is a flexible pipe body, with one end connected to the connecting rigid pipe 312 and the other end connected to the constant pressure gas delivery component 350.

[0031] Preferred, such as Figure 5 As shown, in order to reduce the impact of debris detached from the grate bar 001 accumulated on the top jet block 310, thereby affecting the gravity of the top jet block 310 and thus the measured data, the top of the top jet block 310 is sharp.

[0032] Preferably, the jet feedback component 300 has two rows, located on both sides of the vibratory cleaner 100, and is used to detect the clogging of the grate bar 001 and the cleaning effect.

[0033] Preferably, the pressure sensor is replaced with an impact force sensor; the impact force sensor is connected to the control unit and displays the force state of the top jet block 310 by the change in impact force.

[0034] Preferably, the jet feedback component 300 is positioned close to the vibrating sweeper 100, and by observing the change in the detected impact force, it can be determined whether debris has been shaken off and the amount of debris shaken off.

[0035] Considering that the impact (impact) response of the jet feedback component 300 can affect the detection of debris being shaken off and the amount of debris shaken off, which can easily affect the detection of clogging of the grate bar 001, and that visual observation of the amount of debris shaken off by operators is inaccurate, requires a high level of experience, involves a large amount of manual intervention, and is prone to misjudgment, it is not conducive to promotion and application; preferably, the sintering trolley cleaning device of this application also includes a receiving and weighing component 200; the receiving and weighing component 200 is located directly below the vibrating cleaner 100 and is used to weigh the amount of debris shaken off accumulated in a part of the area directly below the grate bar 001 per unit time to quantify the cleaning effect (observing and comparing the measured clogging situation and the weighing results can determine the cleaning effect); the receiving and weighing component 200 includes positioning The system comprises a base 210, a rotating frame 220, a top receiving container 230, and a weighing module 240 on the ground. The rotating frame 220 is a rigid support that rotates around an axis parallel to the ground and is connected to the base 210. It rotates under the coordinated control of a power component and a control unit. The top receiving container 230 is a plate-shaped container with an open top and is positioned on top of the rotating frame 220. The weighing module 240 is used to weigh the weight of the object carried in the top receiving container 230 and is positioned between the top receiving container 230 and the rotating frame 220, which is existing technology. After the receiving weighing component 200 measures the amount of object carried by the top receiving container 230 per unit time, the object is tilted, re-loaded, and weighed. When it is determined from the data measured by the receiving weighing component 200 that there is a problem with the amount of material shaken off, a reverse investigation is promptly conducted.

[0036] To further improve the applicability of the jet feedback assembly 300, the spacing between the top jet block 310 and the grate bar 001 can be flexibly adjusted as needed; preferably, such as Figure 6As shown, the jet feedback assembly 300 also includes a drag adjustment assembly; the drag adjustment assembly includes a restraint rope 361 and an adjustment bolt 362; the top of the bottom load frame 340 is provided with a through hole for the restraint rope 361 to pass through; the restraint rope 361 is a vertical rope, one end of which is fixed to the bottom of the connecting plate 320, and the other end is positioned on the adjustment bolt 362, and is always in a taut state; the adjustment bolt 362 is tightened and fixed on the rotating frame 220, and is vertically arranged. When the adjustment bolt 362 is rotated, the connecting plate 320 can be dragged up and down to change the distance between the top jet block 310 and the grate bar 001 and adjust the sensitivity of the detection data.

[0037] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: This invention solves the problems of high labor intensity and low work efficiency in the existing technology of manually vibrating to clean the sintering trolley grate bars, as well as the technical problems of mechanically vibrating to clean the trolley grate bars causing significant damage to the grate bars and being unable to reliably and effectively determine the local blockage situation and flexibly adjust the vibration frequency. It achieves the technical effect of the sintering trolley cleaning device in ensuring the vibration effect while minimizing damage to the grate bars, and effectively determining the local blockage situation and flexibly adjusting the vibration frequency.
