Description

Technical Field

[0001] The invention relates to a deep well casting device, in particular to a deep well casting device which utilizes an aluminum water pump to control the flow of aluminum liquid. Background Art

[0002] At present, most aluminum rod production in my country adopts deep well casting technology. The traditional fixed furnace site layout is that the furnace drain port is higher than the casting plate. This layout has several major safety hazards. First, when the furnace drain port fails, it is difficult to block the aluminum liquid, resulting in aluminum leakage accidents; second, when the casting plate fails and production cannot continue, there will be a lot of high-temperature molten aluminum liquid in the flow channel and casting plate that needs to be handled, which is very cumbersome; third, once an unexpected situation occurs, such as a large amount of aluminum liquid leaking into the casting well or an explosion, when the on-site personnel can no longer reach the site, the aluminum liquid in the furnace will continue to flow in, which will expand the accident or cause a secondary explosion. This traditional layout requires the establishment of a large aluminum liquid emergency pool. At the existing factory site, it is difficult to meet the requirements of a sufficiently large emergency pool layout.

[0003] Now the number of tilting furnaces in aluminum rod production is gradually increasing, but the cost of tilting furnaces is very high, and the cost of later maintenance is relatively high. Due to the strength of the mechanical structure, the capacity of the furnace is also small. In the current market, it is very difficult for most companies to invest and cannot realize the upgrade of this equipment; at the same time, the return speed of the tilting furnace is slow in the event of a power outage or an accident, which is not conducive to accident handling; the existing tilting furnace uses an oil cylinder tilting mechanism to tilt, because the weight of the furnace body itself is very heavy, the oil cylinder production process is different, the quality of the oil cylinder is unstable, and when the oil cylinder fails, the furnace is prone to leakage; at the same time, the existing process structure of the tilting furnace generally has a filter box, and the filter in this filter box will affect the flow rate of the aluminum liquid. An emergency pool needs to be set at the casting tray position to hold the excess aluminum liquid in the casting tray for emergency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a deep well casting device which utilizes an aluminum water pump to control the flow of aluminum liquid in view of the deficiencies in the prior art.

[0005] In order to achieve the above object, the measures taken by the present invention are:

[0006] A deep well casting device that uses an aluminum water pump to control the flow of aluminum liquid, comprising a molten pool and a casting well, a casting pan is installed above the casting well, an aluminum water pool is arranged outside the molten pool, an aluminum water channel connecting the aluminum water pool and the molten pool is arranged between the aluminum water pool and the molten pool, a pump chamber is installed in the aluminum water pool, an aluminum water pump impeller mechanism is installed in the pump chamber, the pump chamber and the casting pan are connected through an aluminum water outlet flow trough, a filter box and a casting pan flow trough that are arranged in sequence, a return water flow trough is installed between the casting pan flow trough and the aluminum water pool, and a drainage gate is installed at the connection between the return water flow trough and the casting pan flow trough;

[0007] The aluminum water pool is provided with an aluminum water pump impeller mechanism fixing seat for installing the aluminum water pump impeller mechanism;

[0008] The drainage gate is connected to a drainage gate switch cylinder;

[0009] A first liquid level sensor and a second liquid level sensor are installed above the water outlet flow channel and the casting plate flow channel respectively;

[0010] The filter box is provided with a filter box discharge port, and the filter box discharge port is connected to the return water flow trough.

[0011] The beneficial effects of the present invention are as follows: 1. The structure is novel, and the cost of the whole set of equipment is much lower than the investment cost of the tilting furnace; 2. The aluminum water pump impeller mechanism is used to improve the aluminum water process. Compared with the fixed furnace flow eye water discharge structure, there is no risk of aluminum leakage from the flow eye; 3. Emergency pools do not need to be set up independently at the flow trough and casting plate positions; 4. The degree of automation is higher, and the liquid level height can be effectively controlled to ensure the stability of the casting liquid level; 5. When abnormal casting occurs, there are many ways to solve the on-site risks. For example, when the power is off, the aluminum water can automatically flow back, or the aluminum water in the flow trough and the water tray can be manually controlled to be emptied; especially when sudden abnormal problems occur , if an explosion occurs, the molten aluminum will not flow out, causing secondary risks, thus ensuring safety; 6. All actions of this device can be manually operated in the case of power failure, and emergency power supply can be omitted or the capacity of the emergency power supply can be reduced; 7. The impeller mechanism of the aluminum water pump lifts the molten aluminum to a certain height and then flows to the water tray. The casting tray can be set higher, which is convenient for observing the situation during the casting process, and is conducive to discovering casting defects and the risk of aluminum leakage. At the same time, it is conducive to cooling water mist and steam diffusion, reducing the occurrence of accidents; 8. When the casting is stopped, all the molten aluminum in the launder, filter box and casting tray can be recovered into the molten pool, reducing the trouble of emptying the molten aluminum on site.

The produced aluminum rod 9 is formed and produced at the lower part of the casting plate 10.

[0015] The aluminum water pool 3 is provided with an aluminum water pump impeller mechanism fixing seat 13 for installing an aluminum water pump impeller mechanism 14 .

[0016] The drainage gate plate 12 is connected to a drainage gate plate switch cylinder 15 .

[0017] A first liquid level sensor 16 and a second liquid level sensor 17 are installed above the water outlet flow channel 6 and the casting plate flow channel 8, respectively.

[0018] The filter box 7 is provided with a filter box discharge port 18 , and the filter box discharge port 18 is connected to the return water flow channel 11 .

[0019] like Figure 1 and Figure 2 As shown in the figure, 20 is the aluminum liquid level line, the deep well casting device designed by the patent of the present invention, 1. The aluminum liquid in the molten pool 1 enters the aluminum pool 3 through the aluminum channel 4; 2. A pump chamber 5 is installed in the aluminum pool 3, and the aluminum pump impeller mechanism 14 in the pump chamber 5 lifts the aluminum liquid in the pump chamber 5 to the aluminum outlet flow trough 6; 3. The aluminum liquid flows from the aluminum outlet flow trough 6, passes through the filter box 7, enters the casting plate flow trough 8, and then flows to the casting plate 10 to cast and produce aluminum rods 9; 4. The first liquid level sensor 16 and the second liquid level sensor 17 above the casting plate flow channel 8 are used to monitor the liquid level heights at two positions, and are used to control the delivery volume of the aluminum water pump impeller mechanism 14, and monitor the liquid level at the same time; 5.
