Description

Technical Field

[0001] This utility model relates to the technical field of molten slag cooling tanks, and more specifically, to a molten slag cooling tank with recirculating cooling capability. Background Technology

[0002] In modern metallurgical, casting and other industrial fields, slag is an unavoidable byproduct of the production process. Slag is usually generated at high temperatures and must be cooled before subsequent treatment, resource utilization or safe discharge.

[0003] A search revealed that publication number CN1470652A discloses a method for flushing blast furnace slag into water slag by installing a flushing box at the tail end of the blast furnace slag trough. The water slag flows into the water slag trough, passes through a steam exhaust hood, and enters a slag pool equipped with a screw conveyor, where the screw conveyor separates the dry slag from the slag pool. During the development of this invention, the inventors discovered the following problems with the existing technology:

[0004] The existing natural cooling of molten slag mainly relies on natural convection and radiation. Without external intervention, the heat exchange rate is slow. The temperature of high-temperature molten slag is usually 1300-1600℃. Under natural cooling conditions, it takes several hours or even longer to drop to the appropriate processing temperature through heat exchange between the air and the surface of the molten slag. This seriously affects the production rhythm and the efficiency of subsequent molten slag processing, resulting in limited overall production capacity.

[0005] Therefore, a circulating cooling slag cooling tank is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a circulating cooling slag cooling tank to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a circulating cooling slag cooling tank, comprising a tank body, the tank body being concave downwards, a guide plate being provided on one side of the tank body, the guide plate being inclined vertically, and a liquid filter plate being fixedly connected to the lower inclined section of the guide plate, and a water pumping assembly being placed on one side of the tank body.

[0008] Preferably, the surface of the liquid filter plate is provided with tiny water leakage holes, and the water leakage holes cover the entire liquid filter plate.

[0009] Preferably, a liquid storage area is provided below the liquid filter plate, the inner wall of the liquid storage area is provided with a sealing coating, and an inlet and outlet are provided on one side of the liquid storage area.

[0010] Preferably, a high-pressure atomizing nozzle is provided on the inner wall of the pool above the guide plate, and the high-pressure atomizing nozzle is provided in two rows.

[0011] Preferably, a cooling pipe is provided above the guide plate and the liquid filter plate, and a connecting pipe is provided at one end of the cooling pipe.

[0012] Preferably, the pumping assembly includes a motor, heat dissipation holes, and a spiral interface. The top of the motor has heat dissipation holes, and the bottom of the motor has a spiral interface.

[0013] Preferably, the pumping assembly includes a cavity, and the bottom of the spiral interface is provided with a cavity. The cavity and the spiral interface are connected by a thread to realize the connection between the motor and the cavity.

[0014] Preferably, the pumping assembly includes a receiving port, an output port, and a base. The receiving port is provided on one side of the cavity, and the output port is provided on the side of the cavity away from the receiving port. The base is provided at the bottom of the cavity.

[0015] Preferably, the connecting pipe is connected to the pumping assembly via a pipeline, so that the pipeline and the coolant inside the storage area form a recirculating structure.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] Compared with existing technologies, this circulating cooling slag cooling pool achieves initial cooling by setting multiple high-pressure atomizing nozzles in the pool body, with the nozzles evenly distributed above and on both sides of the pool body. The coolant droplets sprayed from the nozzles come into full contact with the high-temperature molten slag, quickly removing the heat from the surface of the molten slag.

[0018] Compared with existing technologies, this recirculating slag cooling pool has multiple cooling pipes inside the pool, through which low-temperature coolant flows. A liquid storage area located below the liquid filter plate circulates the coolant through a pumping assembly. The molten slag slowly passes through the gaps between the cooling pipes under gravity, making full contact with the pipes to achieve deep cooling. The cooling pipes are made of materials with good thermal conductivity, such as stainless steel or copper alloy, to improve heat exchange efficiency. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] As attached Figures 1 to 5 The slag cooling tank shown includes a tank body 1, which is concave downwards. A guide plate 2 is provided on one side of the tank body 1. The guide plate 2 is inclined vertically, and a liquid filter plate 3 is fixedly connected to the lower inclined section of the guide plate 2. A water pumping assembly 7 is placed on one side of the tank body.

[0027] Among them: when waste is poured in, the up-and-down tilting design of the guide plate 2 can guide the flow direction of the molten slag, so that the molten slag is distributed more orderly in the pool 1. At the same time, in conjunction with the liquid filter plate 3, it creates conditions for subsequent filtration and cooling. The setting of the water pumping component 7 provides the power basis for the circulation of coolant. Example

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0029] In a preferred embodiment, the surface of the liquid filter plate 3 is provided with tiny drainage holes, and the drainage holes cover the entire surface of the liquid filter plate 3. The surface of the liquid filter plate 3 is covered with tiny drainage holes, allowing only coolant to pass through. While achieving initial separation of molten slag and coolant, the cleanliness of the coolant is ensured, impurities are reduced from entering the circulation system, pipe blockage or impact on cooling effect is avoided, the smoothness and efficiency of coolant circulation are improved, and the service life of the equipment is extended.

[0030] In a preferred embodiment, a liquid storage area 6 is provided below the liquid filter plate 3. The inner wall of the liquid storage area 6 is provided with a sealing coating, and an inlet / outlet 9 is provided on one side of the liquid storage area 6. The sealing coating on the inner wall of the liquid storage area 6 effectively prevents coolant leakage, ensuring the safety and integrity of coolant storage. The inlet / outlet 9 can transport coolant from the cooling pipe 5 to the liquid storage area 6 through a pipe, and vice versa, facilitating the replenishment, discharge, and circulation of coolant, so that the liquid storage area 6 can stably provide coolant to the entire circulating cooling system and maintain the continuous operation of the system.

[0031] In a preferred embodiment, a high-pressure atomizing nozzle 4 is provided on the inner wall of the pool body 1 above the guide plate 2. The high-pressure atomizing nozzle 4 is arranged in two rows. By atomizing the coolant, the contact area between the coolant and the high-temperature molten slag is greatly increased. The atomized coolant can absorb the heat of the molten slag more quickly and fully.

[0032] In a preferred embodiment, a cooling pipe 5 is provided above the guide plate 2 and the liquid filter plate 3. The cooling pipe 5 does not affect the flow and filtration of the molten slag, and can use the coolant in the pipe to perform secondary cooling on the molten slag, thereby increasing the cooling path and further reducing the temperature of the molten slag as it passes through the guide plate 2 and the liquid filter plate 3, thus improving the overall cooling effect. In addition, a connecting pipe 8 is provided at one end of the cooling pipe 5.

[0033] In a preferred embodiment, the pumping assembly 7 includes a motor 701, a heat dissipation hole 702, and a spiral interface 703. The top of the motor 701 has a heat dissipation hole 702, which can dissipate the heat generated by the motor 701 during operation in a timely manner, prevent the motor 701 from being damaged due to overheating, and ensure the stable operation of the motor 701. The bottom of the motor 701 is provided with a spiral interface 703, which facilitates the connection between the motor 701 and the cavity 704, making the connection structure more stable.

[0034] In a preferred embodiment, the pumping assembly 7 includes a cavity 704. The bottom of the spiral interface 703 is provided with the cavity 704. The cavity 704 and the spiral interface 703 are connected by threads to realize the connection between the motor 701 and the cavity 704. This connection method can prevent problems such as loosening and leakage during the pumping process.

[0035] In a preferred embodiment, the pumping assembly 7 includes a receiving port 705, an output port 706, and a base 707. The receiving port 705 is provided on one side of the cavity 704, and the output port 706 is provided on the side of the cavity 704 away from the receiving port 705. The receiving port 705 is responsible for receiving coolant from the liquid storage area 6, and the output port 706 delivers the pumped coolant to the circulation pipe. The base 707 is provided at the bottom of the cavity 704, and the base 707 ensures that the pumping assembly 7 is stably installed.

[0036] In a preferred embodiment, the connecting pipe 8 is connected to the pumping assembly 7 via a pipeline, so that the pipeline and the coolant inside the storage area 6 form a recirculating structure. This design allows the coolant to circulate among components such as the storage area 6, the pumping assembly 7, the high-pressure atomizing nozzle 4, and the cooling pipeline 5, realizing the reuse of the coolant. This not only saves water resources and reduces production costs, but also continuously provides cooling power for molten slag cooling, improving the overall performance and environmental benefits of the molten slag cooling pool.

[0037] The working process of this utility model is as follows: First, the pool body 1 is designed to be concave downwards, providing a suitable space for storing molten slag. This structure is also conducive to the accumulation and distribution of molten slag in the pool. The guide plate 2 is inclined vertically and installed on one side of the pool body 1. Its function is to guide the molten slag from the inlet of the pool body 1 to flow in a specific direction, so that the molten slag can pass through the subsequent cooling and processing stages in an orderly manner. The liquid filter plate 3 is fixedly connected to the lower inclined section of the guide plate 2 and is used to filter the liquid generated during the cooling process of the molten slag and separate impurities. The water pumping component 7 is placed on one side of the pool body 1 and is the key power component for realizing the circulation of coolant.

[0038] When the high-temperature molten slag enters the pool 1, the two rows of high-pressure atomizing nozzles 4 located above the guide plate 2 on the inner wall of the pool 1 start to work. The high-pressure atomizing nozzles 4 atomize the coolant and spray it out. A large number of fine droplets come into full contact with the high-temperature molten slag and quickly remove the heat of the molten slag through heat exchange, thus achieving initial cooling. The atomized coolant has a large surface area, which can absorb the heat of the molten slag more efficiently and accelerate the cooling rate.

[0039] After initial cooling, the molten slag continues to flow downward under the guidance of the guide plate 2. It passes under the cooling pipe 5. There is a certain distance between the cooling pipe 5 and the surfaces of the guide plate 2 and the liquid filter plate 3. Coolant circulates inside the pipe. When the molten slag passes through the cooling pipe 5, it exchanges heat with the cold energy emitted by the pipe to achieve secondary cooling and further reduce the temperature of the molten slag.

[0040] During the slag cooling process, the generated coolant includes the coolant that is not completely evaporated after being sprayed from the high-pressure atomizing nozzle 4, as well as the liquid generated during the slag cooling process. It flows with the slag and passes through the liquid filter plate 3. The surface of the liquid filter plate 3 is covered with tiny water leakage holes, which can effectively filter out impurities in the coolant and only allow the coolant to pass through. Then it flows into the liquid storage area 6 below. The sealing coating on the inner wall of the liquid storage area 6 prevents coolant leakage and ensures the safe storage of the coolant.

[0041] The motor 701 in the pumping assembly 7 is connected to the cavity 704 via a spiral interface 703. The heat dissipation hole 702 on the top of the motor 701 can dissipate the heat generated by the generator 701 in a timely manner, ensuring the normal operation of the motor 701. The receiving port 705 on one side of the cavity 704 is connected to the liquid storage area 6 to receive the coolant in the liquid storage area 6. When the motor 701 starts, it draws the coolant into the cavity 704 from the receiving port 705, and then pumps the coolant out through the output port 706. The output port 706 is connected to the cooling pipe 5 and the high-pressure atomizing nozzle 4 through the connecting pipe 8, so that the coolant can circulate back to the cooling pipe 5 and the high-pressure atomizing nozzle 4 and participate in the cooling process of the molten slag again, forming a recirculating cooling system. The above is the working principle of this recirculating cooling molten slag cooling pool.
