The utility model discloses a self-priming pump water diversion tank water suction system which comprises a water suction pool and a vacuum water diversion tank, the vacuum water diversion tank is connected with one end of a water suction pipe, the other end of the water suction pipe is arranged at the pool bottom of the water suction pool, the input end of a self-priming pump is connected with one end of a self-priming pump water suction pipe, and the other end of the self-priming pump water suction pipe is communicated with the bottom of the vacuum water diversion tank. The output end of the self-priming pump is connected with a self-priming pump drainage pipe, the self-priming pump is installed on a pump foundation, and the joint of the vacuum water diversion tank and the water suction pipe and the self-sealing overflow pipe are located at the same height. The water outlet of the lifting water pump is stable, and the problems that the water outlet of the lifting water pump is unstable and the lifting water pump cannot lift water are solved; and after the self-priming pump is stopped, the self-priming pump can be started without refilling the pump next time, the idling phenomenon is avoided, meanwhile, the whole self-priming pump is automatically controlled, the operation is convenient, and time and labor are saved.

The utility model relates to the technical field of garden equipment, in particular to a drainage channel of a garden road, which comprises a drainage channel assembly arranged on the side face of a road surface body, the drainage channel assembly comprises a main channel assembly, a filter assembly and an extrusion assembly, and the main channel assembly comprises a drainage channel body. Water can flow and be discharged along the bottom of the drainage channel body, solid garbage, fallen leaves and the like can be accumulated in the filtering assembly, the filtering assembly is large in internal size, a large amount of fallen leaf garbage and the like can be stored, and even if the garbage is accumulated, the filtering assembly can be recycled. The sewage can still be discharged from the front filter plate on the side surface of the filter assembly into the drainage channel body to flow out, and can be used for a longer time, so that the time for cleaning and maintaining each time can be prolonged.

The present application relates to the field of calcium carbonate production, and discloses a ball milling system for calcium carbonate production, which solves the problem that the calcium carbonate needs to be combined with an appropriate amount of water for ball milling movement when the ball mill is used for ball milling treatment during the production process, and the operation needs to be repeatedly added by the operator, and the calcium carbonate on the steel ball needs to be flushed with water after ball milling, resulting in low efficiency of calcium carbonate ball milling. When the ball milling of the calcium carbonate is completed, the sleeve is vertically set downward, and the calcium carbonate and water can flow out from the filter holes of the two groups of half-pallet plates, realizing the discharge, so that the ball milling operation of the calcium carbonate with water is effectively solved, and the working efficiency of the calcium carbonate ball milling is improved.

The present invention discloses a closed circulation system for cooling water supply of a crucible and an operation method thereof. The closed circulation system for cooling water supply of a crucible comprises an external circulation water supply system, an internal circulation cooling water system and a water supply tank D. The internal circulation cooling water system for cooling the crucible is a closed circulation system. The external circulation water supply system and the internal circulation cooling water system exchange heat through a heat exchanger E. The external circulation water supply system supplies water to the water supply tank D, and the water supply tank D supplies water to the internal circulation cooling water system. The water supply tank D is connected to a drain through an overflow port. The external circulation water supply system, the internal circulation cooling water system and the water pump outlet of the internal circulation cooling water system are all connected to the drain through a pipeline. The system has high operation stability and high safety.
