Description

TECHNICAL FIELD

[0032] The preferred embodiments of the present application are described below in conjunction with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0033] For reference Figures 1-2As shown, the slag salvaging device according to the embodiment of the present application is arranged on the cyclone 1, and comprises:

[0034] a support frame 2 arranged on the cyclone 1;

[0035] a driving assembly arranged on the support frame 2;

[0036] a transmission assembly 3 arranged on the driving assembly, and having slag buckets 4 arranged thereon at intervals;

[0037] a detector 5 arranged on the support frame 2 and above the cyclone 1, and used for detecting the height of the slag heap in the cyclone 1;

[0038] a controller, when the detector 5 detects that the height of the slag heap in the cyclone 1 exceeds a preset height, the controller controls the driving assembly to drive the transmission assembly 3 to rotate, so that the slag buckets 4 salvage the slag in the slag heap.

[0039] Specifically, the existing cyclone 1 is driven by a motor to rotate the impeller, the blades of the impeller are located at the edge of the cyclone 1, the blades agitate the liquid surface to accelerate the rotation of the water inside, and the protective slag accumulated inside is stacked into a slag heap in the middle of the cyclone. The slag salvaging device provided by the present application can automatically salvage the slag in the cyclone 1 without manual operation, which improves the slag salvaging efficiency and ensures the safety of the operation.

[0040] The slag salvaging device comprises a support frame 2, a driving assembly, a transmission assembly 3, slag buckets 4, a detector 5 and a controller. The support frame 2 is installed on the cyclone 1 and can bear the weight of the driving assembly, the transmission assembly 3 and other components and the acting force generated during the slag salvaging process, so as to ensure that the entire device does not shake or displace during the working process and the slag salvaging operation is smoothly performed. The driving assembly is arranged on the support frame 2 and can drive the transmission assembly 3 to operate, so that the slag buckets 4 can cyclically and reciprocally salvage the slag in the cyclone 1. The output power and the rotation speed of the driving assembly can be adjusted according to the actual slag salvaging requirement. When the slag heap is large and the slag is much, the rotation speed can be increased to speed up the slag salvaging speed; when the slag heap is small, the rotation speed can be reduced to save energy. Thus, the slag salvaging device can adapt to different slag working conditions, and the applicability and energy saving of the device are improved. The detector 5 is arranged on the support frame 2 and above the cyclone 1, and is used for detecting the height of the slag heap in the cyclone 1. It can accurately and timely monitor the change of the height of the slag heap and timely transmit the detected data to the controller.

[0041] The controller is electrically connected with the driving assembly and the detector 5, receives the slag heap height data transmitted by the detector 5, and immediately issues an instruction to control the driving assembly to start when the detector 5 detects that the slag heap height in the cyclone 1 exceeds the preset height, so as to drive the transmission assembly 3 to rotate and make the slag bucket 4 start to pick up the slag material of the slag heap. When the detector 5 detects that the slag heap height decreases to below the preset height, the controller controls the driving assembly to stop running, and completes a slag picking-up operation.

[0042] The transmission assembly 3 can adopt a chain or belt 12 transmission mode, has the characteristics of high transmission efficiency and stable operation, and can ensure that the slag bucket 4 moves according to the predetermined track and improves the slag picking-up efficiency. Meanwhile, the slag bucket 4 is made of wear-resistant material and can withstand the friction and impact of the slag material, prolonging the service life.

[0043] The detector 5 is an acoustic wave detector 5, which can detect the height of the slag heap accumulated at the bottom of the cyclone 1 and input the detected slag heap height data to the controller. The detection time of the detector 5 can be set according to the use requirement.

[0044] Compared with the traditional manual slag picking-up mode, the slag picking-up device has high automation degree, can realize uninterrupted operation, greatly improves the slag picking-up efficiency, reduces the downtime of the cyclone 1 due to slag heap accumulation, and improves the operation efficiency of the cyclone 1. Secondly, without the aid of other equipment such as a crown block, the occupation of the crown block is avoided, the continuity and efficiency of the whole production process are improved. Thirdly, the advanced detection and control technology can accurately grasp the slag picking-up opportunity, avoid invalid slag picking-up operation, and save energy and cost. Finally, the whole slag picking-up process does not need personnel to approach the cyclone 1, eliminates the safety hidden danger caused by operation error or unknown situation in the cyclone 1, and protects the personal safety of the operator.

The driving motor is electrically connected with a controller, the controller can adjust the rotating speed of the motor in real time according to the slag pile height information fed back by the detector 5, the control of the operating speed of the transmission assembly 3 is realized, when the slag pile height is high, the rotating speed of the motor is increased to speed up the slagging speed; when the slag pile height is low, the rotating speed of the motor is reduced to save energy. The plurality of driven wheels 7 are uniformly distributed on the support frame 2, the driven wheels 7 are installed on the support frame 2 through bearing seats, the driven wheels 7 can rotate flexibly, and the frictional resistance to the transmission assembly 3 is reduced.

[0050] Referring to Figures 1-2 As shown in the figure, the transmission assembly 3 includes a transmission chain, the chain is sleeved on the driving wheel 6 and the driven wheel 7, and the transmission chain is in meshing connection with the driving wheel 6 and the driven wheel 7.

[0052] Specifically, the transmission chain and the driving wheel 6 and the driven wheel 7 form meshing transmission, cooperate with the fixedly spaced slag bucket 4, and realize continuous taking and transfer of the slag in the cyclone 11. The transmission chain is driven to circulate by the driving wheel 6, when the slag bucket 4 moves to the slag pile position in the cyclone 1 along the chain, the bucket opening faces the slag pile, cuts into the slag pile under the traction of the chain, and realizes taking of the slag. Through cooperation of the transmission chain and the slag bucket 4, the transmission chain has large carrying capacity, can adapt to taking of high-concentration and large-particle slag, and the rigid connection of the slag bucket 4 and the chain ensures stable taking force and the like.

[0056] Specifically, the support frame 2 comprises a fixed frame 8 and a driven frame 9, the fixed frame 8 is installed on the cyclone 1 and used for fixing the driving assembly, the driven frame 9 is two in number, symmetrically installed on the fixed frame 8 and located on both sides of the transmission assembly 3, and used for fixing the driven wheels 7 at different positions, the driven frame 9 is fixedly connected with the fixed frame 8 and can stably fix the driving assembly, the transmission assembly 3 and the driven wheels 7, thereby improving the stability during use.

[0057] With reference to Figures 1-3 As shown in the figure, the cyclone 1 is provided with a lifting groove, and the lifting driver 10 is arranged between the lifting groove and the fixed frame 8.

[0058] Specifically, the lifting driver 10 is installed between the lifting groove and the top beam of the fixed frame 8, can adjust the position of the slag skimming device according to the height of the slag pile, enable the slag bucket 4 to accurately clean the slag pile from top to bottom, and enable the lifting driver 10 to continuously move the fixed frame 8 downward following the cleaning of the slag pile, thereby improving the cleaning efficiency of the slag pile, when the lifting driver 10 drives the fixed frame 8 to the lowest position, the slag bucket 4 has a certain safety distance from the bottom of the cyclone 1, so that the slag bucket 4 is prevented from colliding with the bottom of the cyclone 1 during use, and the service life is improved.

[0059] The lifting driver 10 is a hydraulic cylinder, and there are two of them, symmetrically installed between the fixed frame 8 and the cyclone 1. In the hydraulic system of the hydraulic cylinder, the electromagnetic reversing valve 16 realizes the lifting action of the lifting driver 10 by controlling the direction of the oil; the throttle valve 14 is used to adjust the lifting speed; and the shunt valve 13 precisely controls the lifting synchronization of the two lifting drivers 10. When the support frame 2 is in a suspended state, the hydraulic control one-way valve 15 locks the hydraulic cylinder oil way to maintain the internal pressure, so as to ensure the stability of the position of the support frame 2; at this time, the electromagnetic reversing valve 16 guides the oil output by the hydraulic pump back to the oil tank, so that the hydraulic system is in an unloading state (pump empty running), thereby saving energy.

[0060] With reference to Figures 1-2 As shown in the figure, the lifting driver 10 is provided with a position sensor.

[0061] Specifically, the lifting driver 10 and the position sensor are electrically connected with the controller, the position sensor is used to detect the height of the lifting driver 10, when the reading detected by the position sensor is the lowest, the slag bucket 4 of the slag skimming device will continue to rotate for one week and then stop, and when the lifting driver 10 is detected at the highest position, the slag skimming device is in a standby state.

[0062] With reference to Figures 1-2As shown, it further comprises adjusting wheels 11 arranged on the driven frame 9, the adjusting wheels 11 are located on both sides of the transmission chain, and a passage for the slag bucket 4 to pass through is formed between the adjusting wheels 11.

[0063] Specifically, the two adjusting wheels 11 are symmetrically installed on the driven frame 9, and the two adjusting wheels 11 are in contact with the two side portions of the transmission assembly 3 to limit the transmission assembly 3. The two adjusting wheels 11 have a passage for the slag bucket 4 to pass through, so that the adjusting wheels 11 do not hinder the slag bucket 4 during limiting the transmission assembly 3.

At the same time, when the transmission assembly 3 needs to be repaired or replaced, the adjusting wheels 11 can be adjusted away from the transmission assembly 3 through the adjusting members to loosen them, which facilitates the replacement or repair operation. When the transmission assembly 3 appears lateral swing due to load change or installation error, the adjusting wheels 11 on both sides will form flexible constraint to the chain, guide the chain to return to the normal track through the rotation of the wheel body, and avoid the chain from derailing.

The setting of the belt 12 is used for transferring the slag material.

[0068] When the controller starts the driving assembly to drive the slag bucket 4 to start slagging, the belt 12 is started synchronously and runs at a preset speed. When the slag bucket 4 stops slagging, the belt 12 continues to run for a period of time to ensure that all the slag on the belt 12 is transported to the end point, and then automatically stops to avoid energy waste. The running state of the belt 12 is monitored in real time by the controller, and the running speed of the belt 12 can be detected in real time through the speed sensor installed on the driving drum. When the speed is abnormal, the controller will immediately issue an alarm and stop the slagging action of the slag bucket 4 to prevent the slag from accumulating on the belt 12.
