Technical Field

The utility model relates to a pump machine technical field especially relates to an prevent stifled sediment stuff pump.

Background

Slurry pumps are pumps suitable for transporting liquids (water) containing suspended solids. The slurry pump belongs to a centrifugal pump in terms of working principle, and conceptually refers to a device which converts electric energy into kinetic energy and potential energy of a medium by a mechanism which increases the energy of a solid-liquid mixed medium under the action of centrifugal force (rotation of an impeller of the pump).

In the field of harmless treatment of electrolytic manganese slag, a slurry pump is required to be used for conveying muddy electrolytic manganese slag in many stages, a slurry pump frequently generates a clogging phenomenon when pumping high-concentration sludge, the clogging is mainly caused by the fact that the sludge staying in the slurry pump is piled up when the slurry pump stops working, the conveying of a pump body is influenced, and slurry cannot be continuously pumped, and the slurry pump needs to be detached and then cleaned when meeting the condition every time.

The utility model adopts the technical proposal that: an anti-blocking slurry pump comprises a volute pump shell, a feeding pipe arranged at the center of one side wall of the pump shell and a discharging pipe tangentially arranged on the outer circumferential wall of the pump shell, and is characterized in that a rotating motor is arranged outside the pump shell at the other side opposite to the feeding pipe, a transmission shaft connected with the rotating motor penetrates through the center of the side wall of the pump shell and extends into a pump cavity, and the transmission shaft is opposite to the center of the feeding pipe; the transmission shaft positioned in the pump cavity is provided with an impeller; the bottom of the pump shell is provided with a water outlet pipe, the pump shell is provided with a plurality of flushing pipes, and each flushing pipe is respectively communicated with a nozzle which is installed on the inner wall of the pump shell and is butted with the inner wall of the pump shell; and valves are arranged on the feeding pipe, the discharging pipe, the flushing pipe and the water outlet pipe.

When slurry is conveyed, valves on the feeding pipe and the discharging pipe are opened, and valves on the flushing pipe and the water outlet pipe are closed, so that the slurry is smoothly conveyed and passed; when the slurry pump is stopped, the valves on the feeding pipe and the discharging pipe are closed, the valve on the flushing pipe is opened firstly, the spray head sprays water into the pump for flushing, and after a period of time, the valve on the discharging pipe is opened to discharge sewage in the pump.

Furthermore, the valves are hoop-type ball valves, and the valves on the flushing pipe and the water outlet pipe are both arranged at the positions, close to the pump shell, of the flushing pipe and the water outlet pipe, so that the slurry is prevented from partially entering the flushing pipe and the water outlet pipe in the operation process of the slurry pump.

Furthermore, the extension line of the center of the pore channel of each spray head is tangent to the outer circular surface of the impeller, and the included angle of the extension lines of the center of the pore channels of two adjacent spray heads is less than 90 degrees, so that the impeller is rotated by power in the washing process, the washing efficiency is higher, and the washing effect is better.

Further, the pump casing is fixed on a base through a pump casing bracket.

Further, the rotating motor is fixed on the base through a motor support.

The utility model has the advantages that: the utility model discloses simple structure, convenient to use has the self-cleaning function, can prevent the interior silt pile knot of pump with mud evacuation in the sediment stuff pump when shutting down, has reduced maintenance, change frequency by a wide margin, has improved work efficiency.
