Description

Technical Field

[0001] This utility model relates to the field of slag discharge machines, and in particular to a scraper slag discharge machine. Background Technology

[0002] A slag discharger is a mechanical device used to separate solid particles from a liquid. It is mainly used in thermal power generation, steel smelting, chemical industry, and wastewater treatment. Its core working principle is to use a scraper, chain, and other transmission systems to scrape up the slag (such as furnace slag and sludge) that has settled at the bottom and transport it to the slag discharge port, thereby achieving slag-water separation.

[0003] When using a slag discharge machine, the slag that has settled at the bottom needs to be transported to the slag discharge port. The slag has a certain weight, and after a long period of use, the conveyor chain of the slag discharge machine may become loose, which can easily lead to slippage and reduce transmission efficiency, making it unsuitable for long-term use. Utility Model Content

[0004] In view of this, the present invention provides a scraper slag discharge machine, the main technical problem to be solved is: to provide a slag discharge machine that can conveniently adjust the tension of the conveyor chain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a scraper slag discharge machine, comprising a slag discharge machine body, the slag discharge machine body comprising a main body, a first rotating shaft movably connected to the right side of the main body, a sprocket provided at the end of the first rotating shaft, a second rotating shaft provided on the left side of the main body, a track fixedly connected to the inner wall of the main body, a motor provided at the upper right end of the main body, a torque limiter installed at the output end of the motor, a transmission chain installed at the end of the torque limiter away from the motor, the transmission chain being sleeved on the sprocket at the end of the first rotating shaft, a conveyor chain installed on the surface of the track, the conveyor chain being sleeved on the first rotating shaft and the second rotating shaft, a spiral tensioning mechanism installed inside the left side of the main body, the spiral tensioning mechanism comprising tensioning frames, the number of tensioning frames being two, a second rotating shaft being installed between the two tensioning frames, a tensioning screw being installed on the outer surface of the tensioning frame, the tensioning screw being installed at the left end of the main body.

[0006] By adopting the above technical solution, the motor drives the first rotating shaft to rotate, which in turn drives the conveyor chain to move, so that the conveyor chain can transport the settled slag to the slag discharge port. By rotating the tensioning screw on the spiral tensioning mechanism, the position of the tensioning frame inside the main body can be adjusted, thereby changing the position of the second rotating shaft inside the main body. When the conveyor chain becomes loose, rotating the tensioning screw moves the second rotating shaft toward the upper left corner of the main body, which can change the tension of the conveyor chain and facilitate the transport of slag by the conveyor chain.

[0007] As a further description of the above technical solution:

[0008] The conveyor chain includes two chains. The chains are installed on the outer surface of the track and are sleeved on the first and second rotating shafts. The inner walls of the two chains are fixedly connected to connecting frames, and a scraper is fixedly connected between the two connecting frames.

[0009] By adopting the above technical solution, the first rotating shaft can drive the chain to move when it rotates, and the chain will drive the scraper to move when it moves. When the scraper moves, it can transport the slag settled at the bottom to the slag discharge port. At the same time, the movement of the scraper can also stir and accelerate the cooling of the slag falling into the body.

[0010] As a further description of the above technical solution:

[0011] The main body is equipped with a slag discharge pipe.

[0012] By adopting the above technical solution, high-temperature slag is added into the main body from the slag discharge pipe. The high-temperature slag comes into contact with the cooling water inside the main body, thereby achieving the purpose of cooling the high-temperature slag.

[0013] As a further description of the above technical solution:

[0014] A drain valve is installed on the side wall of the main body, and a drain outlet for the lower tank is provided on the side wall of the main body.

[0015] By adopting the above technical solution, it is convenient to regularly clean the sludge that settles inside the main body.

[0016] As a further description of the above technical solution:

[0017] The right end of the main body is fixedly connected to a head support, and the motor is mounted on the upper surface of the head support.

[0018] By adopting the above technical solution, the right end of the main body is supported, which facilitates the installation of the motor.

[0019] As a further description of the above technical solution:

[0020] A water supply component is fixedly connected inside the main body. A filter screen is provided on the side wall of the water supply component, and an overflow port is provided on the side wall of the main body.

[0021] By adopting the above technical solution, cooling water is added into the main body from the water supply component, and excess cooling water in the main body is discharged from the overflow port.

[0022] As a further description of the above technical solution:

[0023] The main body is equipped with reversing pressure roller assemblies on both the left and right side walls. Pressure rollers are movably connected to the ends of the reversing pressure roller assemblies, and the chain is located inside the pressure rollers.

[0024] By adopting the above technical solution, the direction of the chain can be changed by the reversing pressure group, which facilitates the movement of the chain within the main body.

[0025] By employing the above technical solution, the scraper slag discharge machine of this utility model has at least the following beneficial effects:

[0026] 1. Compared with the existing technology, this scraper slag discharge machine uses a motor to drive the first rotating shaft to rotate, which in turn drives the conveyor chain, so that the conveyor chain can transport the slag settled at the bottom to the slag discharge port for discharge.

[0027] 2. Compared with the prior art, this scraper slag discharge machine can adjust the position of the tensioning frame inside the main body by rotating the tensioning screw on the spiral tensioning mechanism, thereby changing the position of the second rotating shaft inside the main body. When the conveyor chain becomes loose, rotating the tensioning screw will move the second rotating shaft toward the upper left corner of the main body, which can change the tension of the conveyor chain and facilitate the transport of slag by the conveyor chain.

The conveyor chain 5 is mounted on the second rotating shaft 405, enabling the conveyor chain 5 to transport the settled slag to the slag discharge port. The conveyor chain 5 is mounted on the surface of the track 403. A spiral tensioning mechanism 9 is mounted inside the left side of the main body 401. The spiral tensioning mechanism 9 includes tensioning frames 901, and there are two tensioning frames 901. The second rotating shaft 405 is mounted between the two tensioning frames 901. Tensioning screws 902 are mounted on the outer surface of the tensioning frames 901 and are mounted on the left end of the main body 401. By rotating the tensioning screws 902 on the spiral tensioning mechanism 9, the position of the tensioning frames 901 inside the main body 401 can be adjusted, thereby changing the position of the second rotating shaft 405 inside the main body 401. When the conveyor chain 5 becomes loose, rotating the tensioning screws 902 moves the second rotating shaft 405 toward the upper left corner of the main body 401, which can change the tension of the conveyor chain 5 and facilitate the transport of slag by the conveyor chain 5.

[0037] The conveyor chain 5 includes two chains 501. The chains 501 are mounted on the outer surface of the track 403 and are sleeved on the first rotating shaft 402 and the second rotating shaft 405. Connecting frames 502 are fixedly connected to the inner walls of both chains 501, and a scraper 503 is fixedly connected between the two connecting frames 502. When the first rotating shaft 402 rotates, it drives the chains 501 to move. The movement of the chains 501 drives the scraper 503 to move, thus scraping... When the plate 503 moves, it can transport the slag settled at the bottom to the slag discharge port. At the same time, the movement of the scraper can also stir and accelerate the cooling of the slag falling into the body 401. The left and right side walls of the body 401 are equipped with redirecting pressure roller groups 11. The ends of the redirecting pressure roller groups 11 are movably connected to pressure rollers. The chain 501 is located inside the pressure roller. The direction of the chain 501 can be changed by the redirecting pressure group 11, which facilitates the movement of the chain 501 in the body 401.

[0038] The main body 401 is equipped with a slag discharge pipe 404, through which high-temperature slag is added into the main body 401.

[0040] A water supply component 8 is fixedly connected inside the main body 401. A filter screen is provided on the side wall of the water supply component 8. An overflow port 10 is provided on the side wall of the main body 401. Cooling water is added into the main body 401 from the water supply component 8. Excess cooling water in the main body 401 will be discharged from the overflow port 10.

[0041] Working principle: During use, the position of the tensioning frame 901 inside the main body 401 can be adjusted by rotating the tensioning screw 902 on the spiral tensioning mechanism 9, thereby changing the position of the second rotating shaft 405 inside the main body 401. When the conveyor chain 5 becomes loose, rotating the tensioning screw 902 will move the second rotating shaft 405 toward the upper left corner of the main body 401, which can change the tension of the conveyor chain 5 and facilitate the transport of slag by the conveyor chain 5.
