Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to an oxide treatment device for the inner wall of a flow guide channel of an iron casting machine. Background Art

[0002] Cast iron machine is a kind of equipment that casts molten iron into iron blocks. It is usually composed of chain belt, roller, cast iron mold, etc. Molten iron is poured into the cast iron mold, and gradually cools and solidifies into iron blocks as the chain belt moves. Cast iron machine is widely used in ironmaking plants to cast molten iron produced by blast furnace into iron blocks that are easy to transport and subsequently process.

[0003] During the processing of cast iron machines, the surface of the molten metal is easily oxidized when it flows in the flow channel. The oxidized molten iron forms an impurity film on the surface. When it is introduced into the mold, the impurity film breaks and enters the mold, which is easy to affect the quality of the produced metal, which is extremely inconvenient. Therefore, an oxide treatment device for the inner wall of the flow channel of the cast iron machine is proposed. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1, by Figure 1-6Provided is a device for treating oxides on the inner wall of a flow channel of a cast iron machine, the invention comprises a flow channel 1 and a lifting frame 2 fixed to the outside thereof, and is characterized in that: a driving frame 3 which moves along the vertical direction of the flow channel 1 is arranged on the inner side of the lifting frame 2, a suction roller 4 extending into the flow channel 1 is arranged on the inner side of the driving frame 3, a cooling unit 5 which contacts the suction roller 4 is fixedly installed on the inner side of the driving frame 3, a scraping unit 6 which contacts the suction roller 4 and is located below the cooling unit 5 is fixedly installed on the inner side of the driving frame 3, a distance measuring sensor 7 for detecting the liquid level is fixedly installed on the inner side of the flow channel 1, and the distance measuring sensor 7 is linked with the lifting frame 2 to adjust the position of the driving frame 3.

[0033] Furthermore, a hydraulic rod 21 whose movable end is connected to the driving frame 3 is fixedly installed on the outside of the lifting frame 2, and a limiting slide rail extending to the inside of the driving frame 3 is fixedly installed on the inside of the lifting frame 2. The hydraulic rod 21 is linked to the distance measuring sensor 7.

[0034] When the liquid level changes, the distance sensor 7 first recognizes the change in the liquid level, thereby controlling the hydraulic rod 21 to start driving the drive frame 3 to move, so that the adsorption stick 4 on the inner side of the drive frame always maintains a separation angle with the liquid surface, ensuring that the oxide layer on the liquid surface can be effectively adsorbed.

[0035] Furthermore, a driving motor 31 whose output end is connected to the adsorption roller 4 is fixedly mounted on the outside of the driving frame 3, and the outside of the adsorption roller 4 is knurled.

[0036] Under normal conditions, the driving motor 31 drives the adsorption roller 4 to rotate, and the movement direction of the adsorption roller 4 is from the cooling unit 5 toward the scraping unit 6 .

[0037] Furthermore, the cooling unit 5 includes a cooling frame 51 fixed to the inner side of the driving frame 3, the cooling frame 51 is rotatably connected to a cooling pressure roller 52 in contact with the adsorption roller 4, an atomizing nozzle 54 is fixedly installed on the inner side of the cooling frame 51 facing the contact point between the cooling pressure roller 52 and the adsorption roller 4, and a cooling nozzle 55 is fixedly installed on the inner side of the cooling frame 51 facing the cooling pressure roller 52.

[0038] When the cooling unit 5 cools the adsorption rod 4, atomized water vapor is sprayed out from the atomizing nozzle 54. The atomized water vapor sprayed from the atomizing nozzle 54 evaporates to take away the temperature of the contact point between the adsorption rod 4 and the cooling roller 52. At the same time, the adsorption rod 4 and the cooling roller 52 are preferentially subjected to the first heat exchange when in contact, so that the temperature is initially reduced, and the metal oxide layer adsorbed on the surface of the adsorption roller 4 is solidified and brittle. Subsequently, as the cooling roller 52 continues to rotate, the brittle metal oxide layer can be squeezed to be initially detached, and as it rotates, it can be cooled by the cooling nozzle 55.

[0039] Furthermore, the scraping unit 6 includes a scraping frame 61 fixed to the inner side of the driving frame 3, an elastic member 62 is fixedly installed on the inner side of the scraping frame 61, the other end of the elastic member 62 is fixedly connected to a scraping blade 63 that is squeezed with the adsorption roller 4, and a flushing nozzle 64 is fixedly installed on the inner side of the scraping frame 61.

[0040] Furthermore, the cross-sectional size of the scraper frame 61 in a top view is larger than the cross-sectional size of the cooling roller 52 . The cross-sectional size of the scraper frame 61 is funnel-shaped and tilted toward any end connected to the driving frame 3 . A circulating sewage outlet is provided at the bottom of the scraper frame 61 .

[0041] When the outer surface of the adsorption roller 4 rotates to the scraping unit 6, the initially detached metal oxide layer is quickly peeled off by the prying of the scraping blade 63 and falls into the scraping frame 61. The shape of the scraping frame 61 itself can conveniently collect the metal oxide layer.

[0042] Furthermore, the bottom of the scraper frame 61 is connected to a circulation filter unit 8 through a circulation drain port, and the water outlet of the circulation filter unit is connected to the atomizing nozzle 54, the cooling nozzle 55 and the flushing nozzle 64 respectively.

[0043] Furthermore, the circulating filtration unit 8 includes a detachable filter sleeve 81 connected to the circulating sewage outlet, the other end of the detachable filter sleeve 81 is connected to a circulating water tank 82, and a small water pump 83 connected to the atomizing nozzle 54, the cooling nozzle 55 and the flushing nozzle 64 through a pipeline is arranged outside the circulating water tank 82.

[0044] The circulating water tank 82 is disposed outside the lifting frame 2 and is connected to the detachable filter sleeve 81 through a water pipe and a circulating water pump.

[0045] In particular, the pipeline connected to the circulating water tank 82 can be partially placed in the driving frame 3 to prevent collision with the flow channel when moving up and down.

[0046] In particular, the outside of the circulating water tank 82 is connected to a water supply pipe and a water level sensor is provided inside. When excessive water evaporates, cooling water is replenished through the water supply pipe;

[0047] When the small water pump 83 pumps out the circulating water through the flushing nozzle 64, it can flush the inside of the filter sleeve 81, flush the scraped oxidized metal into the filter sleeve 81, and further prevent the oxidized metal from accumulating.

[0048] Working principle:

[0049] Under normal conditions, when the molten metal flows in the flow channel, the distance sensor 7 controls the contact surface between the adsorption stick 4 and the liquid surface to be constant. At the same time, when the adsorption stick 4 contacts the liquid surface, under the influence of the outer surface of the knurling, the metal oxide layer on the surface of the liquid surface can be adsorbed and initially solidified on the surface of the adsorption stick 4, thereby achieving adsorption of the oxide layer film in the flow channel;

[0050] After the adsorption is completed, as the adsorption rod 4 continues to rotate, its surface is cooled and preliminarily treated by the cooling unit 5, the external solidified oxidized metal is completely peeled off at the scraping unit 6, and it reaches the liquid surface again to start adsorption. After the scraping is completed, the circulating filtration unit 8 and the scraping unit 6 itself can also be used to collect the scraped oxidized metal and circulating water, so that the recycling treatment can be conveniently carried out.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
