Description

Technical Field

[0001] The utility model relates to the technical field of ore trough sewage treatment, in particular to a sewage recycling device for a blast furnace trough. Background Art

[0002] The blast furnace ore trough is used to store the raw ore fuel required for blast furnace production. The sintered ore, pelletized ore, lump ore and other raw materials required for blast furnace production are transported to the blast furnace ore storage trough by belt conveyor through the feeding system. Over time, dust is easily accumulated under the belt conveyor inside the ore trough and accumulated on the ground around the equipment, causing adverse effects on the working environment, equipment, etc., and needs to be cleaned in time.

[0003] At present, the dust in the ore trough is mainly cleaned manually, and the ground is washed with water after cleaning. The mineral-containing wastewater after cleaning is directly discharged into the river, causing serious environmental pollution and wasting water resources. Therefore, a blast furnace ore trough wastewater recycling device is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a wastewater recycling device for a blast furnace ore tank, which can filter the wastewater after cleaning the ore tank and recycle it, which not only reduces the pollution of the wastewater to the environment, but also saves water resources, and solves the problems mentioned in the background technology.

[0006] Preferably, four footings are installed at the four corners of the bottom of the water tank in a rectangular array. By providing the four footings, the water tank can be stably supported.

[0007] Preferably, the bottom of the filter area is in a concave design, a sewage outlet is provided in the middle, and an electromagnetic valve is installed on the sewage outlet. By providing the sewage outlet, sewage can be easily discharged from the filter area.

[0008] Preferably, an overflow port is installed at the upper right end of the clean water area. By setting the overflow port, water can be automatically discharged from the clean water area when it is full.

[0009] Preferably, two filter screens are equidistantly installed inside the filter frame. By setting the filter screens, the mine sewage can be filtered.

[0010] Preferably, the control box is installed on the front of the water tank, and the control box is electrically connected to the electromagnetic valve, the electric telescopic rod and the water pump. By setting up the control box, it is convenient to control the overall mining tank sewage recovery work.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] When the utility model is used, the sewage after cleaning the ore trough enters the filter area from the filter rack, is filtered by two filter screens and then precipitates in the filter area. As the sewage is continuously filtered and precipitated, the water in the filter area rises and enters the clean water area. The water pump sucks out the clean water through the water inlet pipe and enters the cleaning equipment through the water outlet pipe to clean the ore trough, thereby filtering the sewage after cleaning the ore trough and recycling it, which not only reduces the pollution of sewage to the environment, but also saves water resources.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1 to Figure 2The utility model provides a technical solution for a sewage recycling device for a blast furnace trough: a sewage recycling device for a blast furnace trough, comprising a water tank 1, a filter frame 9 and a control box 18. Four footings 6 are installed at the four corners of the bottom of the water tank 1 in a rectangular array. The left side of the water tank 1 is a filter area 7, and the right side is a clean water area 3. The filter area 7 and the clean water area 3 are connected by design. The bottom of the filter area 7 is in a concave design, and a sewage outlet 4 is provided in the middle. An electromagnetic valve 5 is installed on the sewage outlet 4, and an overflow outlet 15 is installed at the upper right end of the clean water area 3. When the sludge in the filter area 7 needs to be processed after long-term filtration, the electromagnetic valve 5 can be opened through the control box 18 to discharge the sludge from the sewage outlet 4, and when the water in the clean water area 3 is full, it will be automatically discharged from the overflow outlet 15.

[0018] The top of the filter area 7 is designed to be open, and a rectangular notch 8 is opened at the upper left end. The front end of the filter frame 9 is movably installed at the rectangular notch 8 through two round pins 11. Two filter screens 10 are equidistantly installed inside the filter frame 9. Two L-shaped pins 12 are symmetrically installed at the right end of the top of the filter frame 9. Two round pins 16 are symmetrically installed on the front and back sides of the water tank 1. Electric telescopic rods 17 are installed between the two round pins 16 and the two L-shaped pins 12. When in use, the sewage after cleaning the ore tank enters the filter area 7 from the filter frame 9, and is filtered by the two filter screens 10 in the filter frame 9 and precipitated in the filter area 7. As the sewage is continuously filtered and precipitated, the water in the filter area 7 rises and enters the clean water area 3. After the cleaning of the ore tank is completed, the two electric telescopic rods 17 are started through the control box 18. The two electric telescopic rods 17 work to lift the right end of the filter frame 9 high, so that the mineral materials on the two filter screens 10 slide out (if necessary, the filter frame 9 can be manually knocked to accelerate the sliding out of the mineral materials) filter frame 9.

The water inlet pipe 2 extends into the bottom of the clean water area 3, and the other end of the water outlet pipe 13 is connected to the external cleaning equipment. The water pump 14 is started by the control box 18. The water pump 14 works to suck out clean water through the water inlet pipe 2 and enter the cleaning equipment through the water outlet pipe 13 to clean the ore tank. The control box 18 is installed on the front of the water tank 1, and the control box 18 is electrically connected to the electromagnetic valve 5, the electric telescopic rod 17 and the water pump 14.

[0020] When the utility model is used, the sewage after cleaning the ore tank enters the filter area 7 from the filter frame 9, is filtered by the two filter screens 10 in the filter frame 9, and is precipitated in the filter area 7. As the sewage is continuously filtered and precipitated, the water in the filter area 7 rises and enters the clean water area 3. The water pump 14 is started by the control box 18. The water pump 14 sucks out the clean water through the water inlet pipe 2 and enters the cleaning equipment through the water outlet pipe 13 to clean the ore tank. After the cleaning of the ore tank is completed, the two electric telescopic rods 17 are started by the control box 18. The two electric telescopic rods 17 work to lift the right end of the filter frame 9 high, so that the mineral materials on the two filter screens 10 slide out (if necessary, the filter frame 9 can be manually knocked to accelerate the sliding out of the mineral materials). When the sludge in the filter area 7 needs to be processed after long-term filtration, the electromagnetic valve 5 can be opened through the control box 18 to discharge the sludge from the sewage outlet 4.
