Description

Technical Field

[0001] The invention relates to the technical field of leachate filtering devices, in particular to leachate filtering and separating equipment. Background Art

[0002] Metallurgical dust and sludge refers to solid waste generated in the metallurgical process, mainly including dust and sludge in the steel smelting process. These dust and sludge contain valuable elements such as iron, zinc, and carbon, and are important secondary resources. The sources of metallurgical dust and sludge include sintering, blast furnace ironmaking, steelmaking, steel rolling and other processes. The leachate of metallurgical dust and sludge is obtained by chemical leaching. This leachate usually contains a variety of metal ions, such as zinc, iron, nickel, cobalt, etc. These metal ions can be recycled through subsequent separation and purification steps, while the leachate of metallurgical dust and sludge usually contains impurities such as solid particles, impurity particles, heavy metal particles, etc., and it is necessary to select suitable leachate separation equipment for filtration and separation.

[0003] Existing solid particle leachate filtering and separation equipment often uses manual filtration to filter and separate the leachate. For example, China's authorized patent leachate filtering equipment (application number: CN202323045485.X) discloses a soil leachate filtering and separation equipment, including a dissolution chamber, a filtration chamber, a leachate chamber and an ultrasonic device. The dissolution chamber is provided with a liquid inlet and a ventilation mechanism on the periphery. The leachate chamber is provided with a vacuum device. When the leachate needs to be filtered and separated, the air in the dissolution chamber is first replaced with an inert gas through the ventilation mechanism to prevent the formation of bubbles in the air during the filtration process. When the filter membrane surface is broken, local pressure changes may occur, resulting in damage to the filter membrane. The air pressure in the leachate chamber is reduced by the vacuum device, thereby generating an air pressure difference, so that the leachate in the dissolution chamber automatically passes through the filtration chamber into the leachate chamber, reducing manpower consumption and improving work efficiency.

[0004] Although the prior art uses a ventilation mechanism to fully discharge the air dissolved in the solution, reduce the impact of air on the filter membrane of the filter chamber during the filtration process, extend the service life of the filter chamber, and reduce the cost of use, there is a problem that solid particles in the leachate gather at the bottom due to gravity, resulting in the lower part of the filter membrane having a higher utilization rate than the upper part, causing the lower part of the filter membrane to be more easily attached with more impurities, requiring the filter membrane to be replaced more frequently, resulting in a waste of resources and a decrease in work efficiency; therefore, a leachate filtration and separation device is proposed to address the above problems. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art and solve the problem that impurities in the leachate are gathered at the bottom due to gravity, resulting in the lower part of the filter membrane having a higher utilization rate than the upper part, causing the lower part of the filter membrane to be more easily attached with more impurities, requiring more frequent replacement of the filter membrane, resulting in waste of resources and reduced work efficiency, the present invention proposes a leachate filtering and separation device.

At this time, the rotating protrusion abuts against the abutment block, and the abutment block drives the rotating protrusion to rotate, so that the rotating protrusion drives the spring to undergo elastic deformation and accumulate elastic potential energy. When one end of the rotating protrusion rotates to abut against the side of the abutment block close to the rotating axis, the rotating axis can drive the rotating protrusion to pass through the abutment block through the first support plate, so that when the knife gate valve is closed, the driving gear plate can continue to rotate, avoiding the abutment of the rotating protrusion against the abutment block, thereby hindering the rotation of the driving gear plate and causing motion interference, thereby improving the stability and reliability of the device.

[0012] Preferably, the sensing component includes an air pressure sensor arranged on the inner wall of the filter chamber, a sliding shell is fixedly installed on the top of the supporting plate, a slider is fixedly installed on one side of the sliding shell, a screw rod is threadedly installed on the inner wall of the slider, a second motor is installed on one end of the screw rod, and the second motor is connected to an external power supply through a wire; by setting the sensing component, when the filter membrane is damaged or a large number of impurities are attached to the surface, the air pressure sensor can sense that the air pressure on the side of the filter membrane close to the dissolution chamber is higher than normal or lower than normal.

[0020] 2. The present invention sets a sensing component. When the filter membrane is damaged or a large amount of impurities are attached to the surface, the air pressure sensor can sense that the air pressure on the side of the filter membrane close to the dissolution chamber is higher or lower than normal. At this time, the air pressure sensor can send a signal to control the start-up of the two second motors, so that the second motor on the side of the filter membrane to be replaced drives the filter membrane out of the filter chamber through the screw rod, slider, sliding shell, bearing plate and rotating fixed disk, and drives the filter membrane to move into the filter chamber through the second motor on the side of the spare component through the screw rod, slider, sliding shell, bearing plate and rotating fixed disk to complete the replacement of the filter membrane. This avoids the problem that when the filter membrane is damaged or a large amount of impurities are attached to the surface, it is difficult for the staff to replace the filter membrane in time, resulting in a decrease in the filtration and separation efficiency of the leachate, thereby improving the filtration and separation efficiency of the device.

[0046] When the surface of the filter membrane 8 is damaged or a large amount of impurities are attached to the surface of the filter membrane 8, when the air pressure sensor 31 detects that the air pressure on the side of the filter membrane 8 close to the dissolution chamber 1 is higher than normal or lower than normal, the air pressure sensor 31 sends a signal to control the first motor to start in reverse, so that the first motor controls the knife gate valve 2 to close. At this time, the air pressure sensor 31 sends a signal to control the second motor 35 of the standby component to start, so that the second motor 35 controls the screw rod 34 to rotate, and the screw rod 34 drives the slider 33 to move toward the filter chamber 3, the slider 33 drives the sliding housing 32 to move, the sliding housing 32 drives the bearing plate 7 to move, the bearing plate 7 drives the rotating fixed disk 9 to move, and the rotating fixed disk 9 drives the filter membrane 8 to move. The filter membrane 8 of the spare component moves into the filter chamber 3, and at the same time, the slider 33 drives the connecting concave rod 13 to move, so that the connecting concave rod 13 moves to fit with the abutting convex tooth block 36, so that the first motor drives the rotating component in the spare component to operate through the driving gear plate 19, the fourth bevel gear 18, the third bevel gear 17, the driving rod 16, the first synchronous belt 15, the connecting convex rod 14 and the second synchronous belt 20. At the same time, the air pressure sensor 31 sends a signal to control the start of the second motor 35 of the component to be replaced, so that the second motor 35 drives the filter membrane 8 to move away from the filter chamber 3 through the screw rod 34, the slider 33, the sliding shell 32, the bearing plate 7 and the rotating fixed disk 9, so as to facilitate the staff to replace it.
