[0002] In recent years, my country's steel enterprises have put forward higher and higher requirements for energy conservation and emission reduction. Therefore, various dust removal facilities are installed in each hot rolling production line to collect dust overflowed during rolling. Plastic sintered plate dust collector is a commonly used dust removal equipment for hot rolling production line. Plastic sintered plate dust collector filters the dust and collects it in the dust collector hopper for regular transportation.

[0003] The dust from the plastic-sintered plate of the hot rolling production line is dry powder in summer and muddy in winter, so most of them are transported regularly by self-unloading ash trucks. The ash truck stops under the ash hopper of the dust collector, and then opens the ash discharge valve, and the dust falls into the truck's compartment by its own weight. The self-unloading ash truck then transports the dust to the iron oxide disposal site of the turbid water treatment pool, and the dust is recovered together with the iron oxide. However, there are the following problems in practice:

[0004] 1. When the dust ash is loaded from the ash hopper to the dump truck, dust will overflow in summer and mud will fall in winter, causing secondary pollution. The dump truck also has the above-mentioned secondary pollution problem when unloading the dust ash to the iron oxide material yard.

[0005] 2. When using a dump truck to transport dust ash, sometimes the dust cannot be unloaded in time, resulting in too much dust in the dust collector hopper, affecting the safe operation of the dust collector.

[0006] Therefore, it is necessary to design a system that can automatically transport dust removal ash. Utility Model Content

[0027] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0028] like Figure 1 As shown, an automatic dust removal and ash conveying device for plastic sintered plates in a hot rolling production line comprises:

[0029] A turbid water treatment tank 9, which is connected to a wire-binding slag flushing ditch 8;

[0030] The ash conveying pipeline 5, the input end of the ash conveying pipeline 5 is connected to the output end of the turbid circulating water treatment tank 9, the output end of the ash conveying pipeline 5 is connected to the wire-binding slag-flushing groove 8 and the tank body of the turbid circulating water treatment tank 9, the ash conveying pipeline 5 passes through each plastic-sintered board dust collector 1 in turn, and is connected to the dust collector ash hopper 2 of the plastic-sintered board dust collector 1 through the star-shaped ash unloading valve 3, and can flush the dust ash into the wire-binding slag-flushing groove 8 through the turbid circulating water.

[0031] Specifically, the turbid circulating water treatment pool 9, the wire-binding slag flushing groove 8 and the ash conveying pipeline 5 constitute a water circulation structure. When unloading ash, the star-shaped ash unloading valve 3 is opened to allow the dust-removed ash to fall into the ash conveying pipeline 5. The turbid circulating water treatment pool 9 provides turbid circulating water to flush the dust-removed ash in the ash conveying pipeline 5, and the dust is flushed into the wire-binding slag flushing groove 8. The closed ash unloading is realized, the environment is protected, and the ash unloading process and steps are simplified, which makes the ash unloading operation more convenient.

[0032] Furthermore, according to the position distribution of the plastic sintered plate dust collector 1, it is selected to directly return to the pool body or to return to the pool body through the wire-binding slag-flushing groove 8. The main components of the plastic sintered plate dust ash are Fe2O3 and Fe3O4, which are the same as the main components of the original iron oxide scale in the wire-binding slag-flushing groove 8, and the amount of dust ash is very small compared with the original iron oxide scale in the slag-flushing groove, and the weight ratio is about 0.5%, which has no effect on the equipment of the turbid water treatment pool 9. The turbid water treatment pool 9 separates the dust ash and the rolling mill iron oxide scale from the water together, and piles them in the iron oxide scale yard, avoiding the construction of a separate dust ash water treatment system to separate water and dust ash, reducing space occupancy and funds.

[0033] In this embodiment, the star-shaped ash discharge valve 3 is arranged at the lower end of the dust collector ash hopper 2, and the star-shaped ash discharge valve 3 is connected to the ash conveying pipeline 5 through a detachably connected ash discharge short pipe 4.

[0034] Specifically, the ash unloading short pipe 4 compensates for the distance between the star-shaped ash unloading valve 3 and the ash conveying pipeline 5 , and at the same time, when the ash unloading short pipe 4 is removed for maintenance, a space is provided for the inspection and replacement of the star-shaped ash unloading valve 3 .

[0035] In this embodiment, a first inspection hole 6 is provided on the ash conveying pipeline 5 . The first inspection hole 6 is close to the star-shaped ash discharge valve 3 and is used to observe the ash discharge status of the corresponding star-shaped ash discharge valve 3 .

[0036] Specifically, the first inspection hole 6 is used to observe whether the dust discharge of each plastic sintered board dust collector 1 is normal.

[0037] In this embodiment, a plurality of second inspection holes 7 are provided on the ash conveying pipeline 5 , and the second inspection holes 7 divide the ash conveying pipeline 5 into a plurality of sections.

[0038] Specifically, the second inspection hole 7 divides the ash conveying pipeline 5 into multiple sections, which is convenient for checking the blockage position when it is blocked.

[0039] In this embodiment, the output end of the turbid circulating water treatment tank 9 is connected to the ash conveying pipeline 5 through an inlet pipe 11, and a manual valve 12, an electric valve 13 and a flow switch 14 are sequentially arranged on the inlet pipe 11.

[0040] Specifically, the manual valve 12 is normally open and closed during maintenance. The electric valve 13 is convenient for remote control. The flow switch 14 automatically adjusts the turbid circulating water flow according to the preset to adapt to different ash discharge modes. It can also remind the controller not to continue unloading ash when there is a water outage or water shortage, so as to avoid the dust collection ash from accumulating due to failure to be flushed away in time.

[0041] In this embodiment, a controller and a timing module are also included. The star-shaped ash unloading valve 3 is provided with an electric drive mechanism for opening and closing. The controller is electrically connected to the electric valve 13, the flow switch 14 and the electric drive mechanism. The controller starts the electric valve 13 intermittently and delays the start of the star-shaped ash unloading valve 3 after starting the electric valve 13.

[0042] Specifically, the electric drive mechanism is used to drive the star-shaped ash discharge valve 3 to open and close. When in use, turbid water is circulated first, and then ash is discharged. When closed, ash discharge is stopped first, and then circulating water is stopped, so as to reduce blockage of the ash conveying pipeline 5 and avoid dust accumulation.

[0043] Furthermore, each star-shaped ash unloading valve 3 is respectively provided with an electric drive mechanism, and the electric drive mechanism also includes a delay module, through which each star-shaped ash unloading valve 3 is alternately unloaded, thereby extending the time and reducing the load of the ash conveying pipeline 5 .

[0044] In this embodiment, the ash conveying pipeline 5 is provided with an inclined slope, and the lengths of the various ash unloading short pipes 4 are different.

[0045] Specifically, by setting the slope, it is convenient for water flow to transport dust, and it is also possible to avoid siltation and corrosion in the ash conveying pipeline 5. The preferred slope is 2-3%.

[0046] In this embodiment, the turbid circulating water treatment tank 9 includes a tank body and at least one water pump 10 , and the output end of the water pump 10 is connected to the water inlet pipe 11 .

[0047] Specifically, each pumping pump 10 provides dirty circulating water for different purposes, independently of each other, to avoid the flow rate of dirty circulating water being affected by fluctuations in water supply.

[0048] In this embodiment, a check valve is provided between the water inlet pipe 11 and the ash conveying pipe 5 .

[0049] Specifically, the check valve prevents turbid circulating water mixed with dust from flowing back when blocked, thereby protecting the safety of various switches and pumps.

[0050] In this embodiment, the diameter of the ash conveying pipeline 5 is larger than that of the water inlet pipeline 11 .

[0051] Specifically, the diameter of the ash conveying pipeline 5 is larger than the water inlet pipeline 11, so as to ensure sufficient space for conveying dust ash.

[0052] In this embodiment, when the automatic conveying device for dust removal of plastic sintered plates in a hot rolling production line is used, the use of multiple plastic sintered plate dust collectors 1 for dust removal is taken as an example:

[0053] The dust unloading time is preset. When the time comes, the controller controls the electric valve 13 to open, and the star-shaped dust unloading valve 3 is opened after the turbid circulating water circulates stably (at least for the stable time after the pump is started), so as to prevent the dust from accumulating in the ash conveying pipeline 5;

[0054] After the ash unloading is completed, the star-shaped ash unloading valve 3 is closed first, and then the circulation of the turbid circulating water is stopped after a delay, so that the turbid circulating water can clean the dust in the ash conveying pipeline 5;

[0055] The dust ash enters the wire-binding slag flushing ditch 8 and enters the turbid circulating water treatment tank 9 together with the iron slag.

[0056] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
