Description

Technical Field

[0001] This utility model belongs to the field of chemical and hydrometallurgical technology, and specifically relates to an inlet filter device for a slurry pump. Background Technology

[0002] Slurry pumps, as core conveying equipment in the chemical and hydrometallurgical fields, play a crucial role in transferring materials. They are suitable for transporting solid materials, after being slurried with liquid, to the next processing area. This equipment ensures smooth and stable production by transferring materials from one stage to the next. However, in the current chemical and hydrometallurgical fields, the slurrying of solid materials with liquid cannot guarantee complete dissolution; large particles may still remain. If these large particles enter the slurry pump during transport, they can easily damage the impeller and clog the pipes, leading to high maintenance costs and significant economic losses. Furthermore, the time-consuming maintenance and replacement of slurry pumps, coupled with high labor intensity for employees, severely impacts production start-up time and efficiency. Summary of the Invention

This device intercepts large particles on the left side of the filter plate, preventing them from entering the slurry pump, thus avoiding impeller damage and pipe blockage, extending the pump's service life, reducing maintenance costs, decreasing labor intensity, and minimizing downtime for repairs, thereby effectively improving production efficiency. When the filter plate becomes clogged, a pulse cleaning device can be activated to inject clean water for reverse cleaning, effectively extending the manual cleaning cycle.

[0015] This utility model discloses an inlet filtration device for a slurry pump. The slurry pump inlet filtration device mainly includes a mixing tank 1, a filter box 2, a filter plate 3, a slurry pipe 4, a valve 5, and a pulse cleaning device. The filter box 2 is installed on the bottom side of the mixing tank 1, and the mixing tank 1 is connected to the filter box 2. The top of the filter box 2 is provided with an insertion hole 21. The filter plate 3 is inserted into the filter box 2 through the insertion hole 21. The filter plate 3 and the insertion hole 21 are sealed by a sealing ring. The filter plate 3 divides the inside of the filter box 2 into a particle chamber 22 and a feeding chamber 23. The slurry pump is connected to the feeding chamber 23 through the slurry pipe 4. The valve 5 is installed on the slurry pipe 4. The pulse cleaning device is connected to the feeding chamber 23 and is connected to the plant's water supply system. The material is stirred and slurried in the mixing tank 1. During operation, the fully slurried material enters the feeding chamber 23 through the filter plate 3 and is supplied to the slurry pump, ensuring that the material meets the specifications of the slurry pump. The filter plate 3 intercepts large particles of material on its left side, preventing them from entering the slurry pump, thus avoiding impeller damage and pipe blockage. This extends the service life of the slurry pump, reduces maintenance costs, reduces the labor intensity of employees, and minimizes downtime for maintenance, effectively improving production efficiency. When the filter plate 3 becomes clogged, a pulse cleaning device can be driven to inject clean water to clean the filter plate 3 in reverse, effectively extending the manual cleaning cycle.

The two ends of the water pipe 6 are connected to the feeding chamber 23 and the water supply system, respectively. The pulse valve and the pulse pump are both installed on the water pipe 6. During cleaning, the valve 5 is closed, and clean water is pulsed into the feeding chamber 23 through the pulse valve and the pulse pump, thereby cleaning the material blocked on the filter plate 3 in reverse, extending the manual cleaning cycle and reducing downtime for maintenance.

[0018] The filter box 2 is provided with a sliding groove 7 for limiting the position of the filter plate 3. The filter plate 3 is inserted into the sliding groove 7, and the sliding groove 7 limits the position of the filter plate 3 to ensure the stability of the filter plate 3.

[0019] The filter box 2 is provided with a primary filter screen 11 at the connection between it and the mixing tank 1.

During operation, the fully slurried material enters the feeding chamber 23 through the filter plate 3 and is then transported by the slurry pump. The filter plate 3 intercepts large particles of material on its left side, preventing them from entering the slurry pump and avoiding impeller damage and pipe blockage. This extends the service life of the slurry pump, reduces maintenance costs, lowers the labor intensity of employees, and reduces downtime for maintenance, effectively improving production efficiency. When the filter plate 3 becomes clogged, a pulse cleaning device can be driven to inject clean water to clean the filter plate 3 in reverse, effectively extending the manual cleaning cycle.
