Description

Technical Field

[0001] This utility model relates to a cooling device for the power and environmental protection operation area of ​​a steel plant, and more particularly to a water pump anti-sludge device. Background Technology

[0002] In the steel production sector, the normal and safe operation of the power and environmental protection work area is a core link in ensuring the smooth operation of the entire production process, and it has profound significance for the stable operation of steel enterprises and the guarantee of product quality. This process involves several key considerations, among which ensuring the safe handover of production in the power and environmental protection work area, effectively saving energy costs, and improving product quality are issues that steel enterprises are continuously concerned about.

[0003] In the continuous casting production process, cooling water plays a crucial role. Its main function is to accelerate the cooling process of the steel billet after casting. Cooling the billet significantly improves the density and uniformity of its internal structure, thereby optimizing its quality. Furthermore, the quality and effectiveness of the cooling water greatly influence the quality and surface finish of the final product, directly impacting its market competitiveness and economic benefits.

[0004] Currently, in the continuous casting cooling water supply system of the power and environmental protection operation area, water is typically drawn from a turbid circulating water tank using pumps to cool the steel billets. However, the water source for the turbid circulating water tank is recycled water, which contains a large amount of impurities. Over time and with continuous production, a sludge layer gradually forms at the bottom of the turbid circulating water tank. This problem brings many inconveniences and potential risks. Due to the continuous accumulation of sludge, frequent manual cleaning is required. In actual operation, if cleaning is not done in a timely manner, it can easily lead to blockages in the continuous casting cooling water pipes and nozzles, which can seriously affect normal production, resulting in a series of adverse consequences such as production interruption, equipment damage, and unstable product quality.

[0005] In other words, the continuous casting cooling water system in the power and environmental protection operation area of ​​the existing steel production has many problems caused by the large amount of impurities in the turbid circulating water pool. These problems urgently need to be solved and improved to meet the urgent needs of steel enterprises for stable production, improved product quality and reduced operating costs. Summary of the Invention

[0006] This utility model addresses the shortcomings of existing technologies by providing a water pump anti-sludge device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: the water pump anti-sludge suction device includes a suction pipe connected to the pump, the first end of the suction pipe is connected to the pump inlet, the second end of the suction pipe extends into the turbid circulating water tank, and a filter assembly is installed at the second end of the suction pipe. The absorption pipe is used to transport the filtered water to the pump.

[0008] The filter assembly is connected to a float via a suspension mechanism, ensuring that the filter assembly is suspended in the water without contacting the bottom silt layer.

[0009] Furthermore, it also includes a level sensor, which is installed in the turbid circulating water tank (8) to detect the lowest water level.

[0010] Furthermore, it also includes a second liquid level sensor, which is installed in the turbid circulating water pool to detect the highest water level.

[0011] Furthermore, it also includes a supply pipe, one end of which extends into the turbid circulating water pool to replenish the water source for the turbid circulating water pool.

[0012] Furthermore, the float has sufficient buoyancy to float on the surface of the turbid circulating water tank.

[0013] Furthermore, the float is a buoy, and the buoy has a hollow structure.

[0014] Furthermore, the suspension mechanism includes a connecting component for fixing the filter assembly within a predetermined height range to avoid contact with sediment at the bottom of the water storage container; the connecting component is a suspension chain, with one end of the chain connected to the bottom of the float and the other end connected to the filter assembly.

[0015] Furthermore, the filter assembly adopts a square hollow structure, which has an interface connected to the water suction pipe (5). The outer surface of the square hollow structure is distributed with filter holes to prevent large particles of impurities from entering the water suction pipe.

[0016] Furthermore, the turbidity circulation pool is used to store water to be pumped out.

[0017] Furthermore, the pump's outlet is connected to the continuous casting cooling pipe, which is used to transport the water drawn from the suction pipe to the continuous casting billet production process.

[0018] Compared with the prior art, this utility model has the following advantages.

[0019] This utility model's water pump anti-sludge suction device employs a float (float mechanism) installed in the turbid circulating water tank. The filter assembly of the suction pipe can be connected to the bottom of the float via a chain, preventing water from being drawn from the bottom of the tank and effectively preventing blockages in the suction pipe system. Furthermore, the filter assembly effectively blocks large particles of impurities in the water from entering the suction pipe system, further preventing blockages. Attached Figure Description

[0024] To make the objectives, technical solutions, and beneficial effects of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] like Figure 1-2 As shown, the water pump anti-sludge suction device includes a suction pipe 5 connected to the pump 6. The first end of the suction pipe 5 is connected to the inlet of the pump 6, and the outlet of the pump 6 is connected to the continuous casting cooling pipe 9, used to transport water drawn from the suction pipe to the continuous casting billet production process. The second end of the suction pipe 5 extends into a turbidity circulation tank 8, which stores the water to be pumped. A filter assembly 4 is installed at the second end of the suction pipe 5, and the suction pipe 5 is used to transport the filtered water to the pump. The filter assembly 4 is connected to a float via a suspension mechanism, ensuring that the filter assembly is suspended in the water and does not contact the bottom sludge layer 1.

[0026] Example 1: To ensure the water level in the circulating water tank 8 remains within a safe and effective operating range, the device is additionally equipped with two important level monitoring devices: level sensor 10 and level sensor 21. Level sensor 10 detects the lowest water level to trigger an alarm signal and initiate water replenishment. Level sensor 21 detects the highest water level to trigger an alarm signal and stop water replenishment. Level sensor 21 is located above level sensor 10 and operates based on sensitive detection of water level changes. Once the water level drops below a preset critical value, level sensor 10 immediately triggers an alarm signal and initiates water replenishment to ensure the normal operation of the system is not affected. Level sensor 21 monitors the highest water level. When the water level rises to a set safe upper limit, level sensor 21 emits another crucial alarm signal. This signal prevents overfilling by promptly triggering a stop-water replenishment operation, avoiding potential overflow risks and protecting the surrounding environment from unnecessary water waste and potential damage.

[0027] Example 2 also includes a supply pipe 7, one end of which extends into the turbid circulating water tank to replenish the tank with water. When level sensor 1 issues an alarm signal, it indicates that the water level in the turbid circulating water tank is below a preset minimum value, and the supply pipe is activated to replenish water. Conversely, when level sensor 2 issues an alarm signal, it indicates that the water level has reached a preset maximum value, and the supply pipe should be stopped.

[0028] Example 3: The core of the floating system is a float 2 with sufficient buoyancy. It can not only float stably on the surface of the turbid circulating water tank 8, but also maintain the filter assembly 4 suspended in a suitable position even when the liquid level changes significantly. The floating body uses a float 2, which is a hollow structure. This hollow structure design not only reduces the weight of the float itself and increases buoyancy, but also allows it to be easily adjusted according to different buoyancy requirements. The float can be made of the following materials depending on the buoyancy requirements: polyethylene (PE), polypropylene (PP), glass fiber reinforced plastic (FRP), polyurethane foam, or composite materials: carbon fiber or glass fiber combined with resin.

[0029] Example 4: The suspension mechanism includes a connecting component for fixing the filter assembly within a predetermined height range to avoid contact with sediment at the bottom of the water storage container. The connecting component is a chain 3, with one end of the chain 3 connected to the bottom of the float 2 and the other end connected to the filter assembly 4. The chain 3 is made of high-strength, corrosion-resistant materials, such as stainless steel, and its length can be set as a detachable chain structure. Its structure is simple, and its length can be adjusted according to different operating conditions.

[0030] In Example 5, the filter assembly 4 adopts a square hollow structure. This design not only optimizes the water flow path but also provides a larger filtration surface area, thereby improving filtration efficiency and effectiveness. Furthermore, compared to a circular structure, the square structure is more stable in placement within the turbidity circulation tank 8, reducing positional displacement caused by water flow impact or external factors. This square hollow structure has an interface connecting to the suction pipe 5, and its outer surface is distributed with filter holes 12 to prevent large particles from entering the suction pipe. The pore size of the filter holes 12 can be designed according to the required particle size. This effectively blocks large particles, such as silt, pebbles, and other solid materials, from entering the suction pipe 5, protecting the water pump 6 and the subsequent continuous casting cooling pipe 9 from damage.

[0031] The usage process of this utility model is described in conjunction with the accompanying drawings and technical solutions:

[0032] 1. The supply pipeline is responsible for supplying water to the turbid circulating water tank. The turbid circulating water tank is equipped with level detection sensors; level detection sensor one is used for detecting the lowest water level, and level detection sensor two is used for detecting the highest water level. When level sensor one alarms, it means that the water level in the turbid circulating water tank is too low and water needs to be added. At this time, the supply pipeline is controlled to add water to the water tank. When level sensor two alarms, it means that the water level in the turbid circulating water tank is full, and water supply to the water tank can be stopped.

[0033] 2. A circular buoyant ball is placed in the turbid circulating water tank. The buoyancy of the buoyant ball is sufficient to ensure that it always floats on the liquid surface. The bottom of the buoyant ball is connected to the filter assembly via a chain, which keeps the filter assembly suspended in the water, preventing it from sinking to the bottom of the turbid circulating water tank. The filter assembly is connected to the inlet of the suction pipe. The outlet of the suction pipe is connected to the inlet of the pump.

[0034] 3. During the continuous casting billet production process, the pump is started to draw water from the turbid circulating water pool through the suction pipe, and then transport it to the continuous casting billet production end through the continuous casting cooling pipeline.

[0035] 4. Because the inlet of the suction pipe is equipped with a filter component, it can effectively filter out debris in the turbid circulating water tank. At the same time, the filter component is always suspended in the air by the buoyancy ball, which can effectively prevent the inlet of the suction pipe from contacting the sludge layer in the turbid circulating water tank, and effectively prevent the sludge layer from being sucked into the suction pipe.
