Description

Technical Field

[0001] This utility model relates to the field of refractory brick production technology, specifically a refractory brick spray cooling device. Background Technology

[0002] Refractory bricks, also known as fire bricks, are refractory materials made from refractory clay or other refractory raw materials. As a key material in the metallurgical, thermal power, and chemical industries, the high-temperature resistance, chemical stability, and high strength of refractory bricks are crucial. After shutdown, to ensure the refractory bricks are not damaged, a reasonable cooling strategy must be adopted. At high temperatures, refractory bricks cannot be directly cooled with large amounts of water to avoid cracking. Therefore, gradual water cooling is necessary, that is, gently spraying water mist onto the brick surface to gradually reduce the temperature and avoid cracks caused by rapid cooling.

[0003] Chinese patent CN202422010410.6 discloses a "Cooling and Curing Device for Refractory Brick Preparation" (publication number CN223085060U). This device includes a fixed frame, a conveyor motor fixedly mounted on one side of the frame, a drive shaft at one end of the motor, a drive belt on the drive shaft, a conveyor roller fixedly connected to one end of the drive shaft, a collection box on one side of the frame, a first spraying mechanism on the frame, a drive mechanism inside the frame, and a sliding groove on the inner wall of the frame containing a slider. However, this device has some drawbacks: the water sprayed by the device is not recycled, resulting in significant water waste. Utility Model Content

[0004] To address the problems of the prior art, this utility model provides a refractory brick spray cooling device that can collect and filter the sprayed water, recycle water resources, reduce the amount of fresh water used, and save water resources.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a refractory brick spray cooling device, comprising a roller conveying mechanism for conveying refractory bricks, a water collecting hopper disposed below the roller conveying mechanism, a filter unit detachably connected to the lower end of the water collecting hopper, the filter unit being connected to a water tank, a water supply branch pipe fixedly connected to the bottom of the water tank, the water supply branch pipe being connected to a first main pipe, the first main pipe being connected to the inlet of a water pump, a second main pipe being connected to the outlet of the water pump, a drain branch pipe being connected to the second main pipe, the drain branch pipe being connected to a spray pipe, an atomizing nozzle being fixedly connected to the wall of the spray pipe, the spray pipe being fixedly connected to a first baffle plate, and the first baffle plate being fixedly connected to the support of the roller conveying mechanism.

[0006] The above structural design enables the recycling and reuse of cooling water, reducing water waste. At the same time, the atomizing nozzle design ensures that water is sprayed evenly on the surface of the refractory bricks in a mist form, avoiding the problem of rapid cooling caused by excessive water flow.

[0007] Preferably, the lower end of the water collecting hopper has an opening, and a plurality of first stop rods are fixedly connected to the opening at the lower end of the water collecting hopper.

[0008] The above structural design serves as a shield to prevent refractory bricks from falling.

[0009] Preferably, the filtration unit includes a filter cylinder, multiple second stop rods fixedly connected to the bottom of the filter cylinder, a filter frame disposed inside the filter cylinder, and a filter screen fixedly connected to the filter frame. Rubber lips for sealing are fixedly connected to the frame of the filter frame. First flange rings are fixedly connected to both ends of the filter cylinder. Second flange rings matching the first flange rings are fixedly connected to the lower end of the water collecting hopper and the tank wall of the water tank.

[0010] With the above structural design, the dual interception action of the first and second baffles effectively blocks large particulate impurities carried in the cooling water, preventing them from entering the water tank. At the same time, the rubber lip on the filter frame ensures the seal between the filter frame and the filter cylinder, allowing wastewater to flow directly through the gap between the filter frame and the filter cylinder.

[0011] Preferably, a water supply pipe is fixedly connected to the upper part of the water tank, and a switch valve is provided on the water supply pipe.

[0012] With the above structural design, when the water in the tank is insufficient, water can be added to the tank through the water supply pipe, thereby ensuring the continuous operation of the device.

[0013] Preferably, the top end of the first baffle is fixedly connected to the second baffle, and the second baffle is arc-shaped.

[0014] The above structural design can guide the water evaporated from the surface of the refractory bricks back to the water collection hopper, further improving the water resource recycling rate, while avoiding water droplets splashing onto the outside of the device and causing waste.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This device enables efficient recycling and reuse of cooling water. The collection hopper can collect dripping water, and the filtration unit can filter out impurities in the water, preventing impurities from clogging the atomizing nozzles and significantly improving water resource utilization.

[0018] The roller conveyor mechanism 1 is a waterproof roller conveyor. The atomizing nozzle 2 sprays water mist to ensure that the roller conveyor mechanism 1 can work normally. A water collection hopper 21 is set below the roller. The diameter of the opening at the upper end of the water collection hopper 21 is greater than or equal to the width of the roller conveyor mechanism 1 so that cooling water can be collected.

[0019] The lower end of the water collecting hopper 21 has an opening, and multiple first baffles 41 are fixedly connected to the opening at the lower end of the water collecting hopper 21. The first baffles 41 are evenly distributed in the horizontal direction, and a water flow channel is formed between two adjacent first baffles 41.

[0020] The filter unit 22 includes a filter cylinder 201, multiple second baffles 202 fixedly connected to the bottom of the filter cylinder 201, a filter frame 203 disposed inside the filter cylinder 201, and a filter screen 206 fixedly connected to the filter frame 203. The second baffles 202 are evenly distributed in the horizontal direction, and a channel is formed between adjacent second baffles 202. Rubber lips for sealing are fixedly connected to the frame of the filter frame 203. First flange rings 204 are fixedly connected to both ends of the filter cylinder 201. Second flange rings 205 matching the first flange rings 204 are fixedly connected to the lower end of the water collecting hopper 21 and the tank wall of the water tank 23. Bolts are passed through the first flange rings 204, and screw holes matching the bolts are opened on the second flange rings 205. Sealing gaskets are fixedly connected to the first flange rings 204 and the second flange rings 205 to increase the sealing performance of the filter unit 22 after installation and prevent cooling water leakage.

[0021] Multiple sets of filter frames 203 and filter screens 206 are provided. Multiple sets of filter frames 203 can be stacked inside the filter cylinder 201, and the mesh size of each filter screen 206 is different. The mesh size of the stacked filter screens gradually decreases from top to bottom. In order to facilitate the handling of filter frames 203, pull ropes 209 are fixedly connected to the edge of filter frames 203. Each set of filter frames 203 is provided with a pair of pull ropes 209, and pull ropes 209 are fixedly connected to the edge of the filter frames 203 arranged parallel to each other.

[0022] The upper part of the water tank 23 is fixedly connected to the water supply pipe 51, and the water supply pipe 51 is equipped with a switch valve 52.

[0023] To facilitate water replenishment into the water tank 23, the switch valve 52 is an electrically controlled valve, and the water supply pipe 51 is connected to an external water source. A liquid level sensor is installed inside the water tank 23 (not shown in the attached diagram of the instruction manual). The liquid level sensor is electrically connected to the switch valve 52. When the water level in the water tank 23 is lower than the set value, the liquid level sensor sends a signal and automatically opens the switch valve 52 to replenish the water source.

[0024] The top of the first baffle plate 31 is fixedly connected to the second baffle plate 32. The second baffle plate 32 is arc-shaped. Water evaporated from the refractory bricks encounters the second baffle plate 32 and condenses. It then falls from the second baffle plate 32 into the water collection hopper 21 for further recycling of cooling water.

[0025] Working principle: Refractory bricks are conveyed to the area below the spray pipe 5 via the roller conveyor mechanism 1. The water pump 26 delivers cooling water from the water tank 23 to the first main pipe 25 via the water supply branch pipe 24, and then distributes it to multiple drainage branch pipes 28 via the second main pipe 27. The water is then sprayed out through the atomizing nozzles 2 on the spray pipe 5, which evenly spray the water in a mist form onto the surface of the refractory bricks, achieving gradual cooling. Cooling water dripping from the surface of the refractory bricks is collected by the water collection hopper 21. After passing through the first baffle 41 to intercept large particles of impurities, it flows into the filtration unit 22. The filter screen 206 in the filtration unit 22 further filters out fine impurities. The filtered cooling water enters the water tank 23 and is recycled through the water supply branch pipe 24. The water supply pipe 51 is connected to an external water source. When the water level in the water tank 23 is insufficient, the level sensor sends a signal and automatically opens the switch valve 52 on the water supply pipe 51 to replenish the water tank 23, ensuring the continuous operation of the device. Water evaporating from the refractory bricks condenses upon encountering the second baffle plate 32, then drips from the second baffle plate 32 into the water collection hopper 21 for further recycling of cooling water. The upper flange of the filter cylinder 201 is connected to the lower end of the water collection hopper 21, and the lower flange of the filter cylinder 201 is connected to the water tank 23. The filter screen 206 can be removed for cleaning or replacement, ensuring the long-term stable operation of the device.
