Abstract

The jet pump for loosening, collecting and transporting sludge can be used to remove sludge from sewage treatment plants, the anterior chambers of pumping stations, reclamation ponds and sumps.

Description

The utility model relates to the field of pump engineering and can be used to remove sludge from the sediment chambers of pumping stations of sewer sumps.

The purpose of the invention is the development of a device for removing and transporting sludge.

Known jet pump for pumping manure (USSR Author's Certificate No. 1418500 class F04F5 / 10, published on 08/23/1988 Bull. No. 31). However, such a pump is applicable for pumping manure.

Known jet pump for cleaning silty wells and sewer sumps (utility model patent No. 168656 published 02/14/2017, Bull. No. 5). The disadvantage of such a pump, achieved by this utility model, is the inability to flush the suction pipe and pump housing.

Closest to the proposed patent for a utility model is a jet pump for loosening, collecting and transporting compacted sludge deposits (utility model patent No. 181423 published July 13, 2018, Bull. No. 20). The disadvantage of such a pump, achieved by this utility model, is the inability to flush the pump casing during silting.

The technical result achieved by the proposed utility model is the possibility of washing the suction of the external and internal vacuum spaces with a pressure jet.

This fact is achieved by the fact that in the jet pump for collecting and transporting sludge deposits containing a working pipe, a glass, jet nozzles, an external and internal vacuum space, an annular pressure gap, a discharge pipe, pressure pipes of water supply cut into the external and internal vacuum spaces, and in the outlet pipe a valve is installed.

Figure 1 shows a pump diagram for collecting and transporting sludge.

The jet pump for collecting and transporting sludge consists of a working pipeline (1), with an external pipe (2) embedded in it, with an external valve (3), cleaning the external vacuum space (4), with an internal pipe (5), with an internal valve (6), cleaning the internal vacuum space (7), connected to the glass (8), forming with the nozzle (9), an annular pressure gap (10), to the end part of which the jet nozzles (11) are fixed, the pump housing (12) , the front of which is embedded in the discharge pipe (13), with a valve (14).

The pump operates as follows:

The valve (14) opens, water is supplied through a working pipeline (1) under pressure to an annular pressure gap (10) formed by a glass (8) and a nozzle (9), forming external (4) when exiting into the discharge pipe (13), between case (12) and a glass (8), and internal (7) vacuum spaces that facilitate the collection and transportation of silt deposits loosened by jet nozzles (11). In case of clogging of the suction external (4) or internal (7) vacuum spaces, the external valve (3) of the external pipe (2) opens when cleaning the external vacuum space (4) or the internal valve (6) of the internal pipe (5) when cleaning the internal vacuum spaces (7), the valve (14), the outlet pipe (13) closes, and the jet rinses the suction external (4) and internal (7) vacuum spaces with a reverse current.

Claims (1)

A jet pump for loosening, collecting and transporting compacted sludge, containing a working pipe, a glass, jet nozzles, an external and internal vacuum space, an annular pressure slot, a discharge pipe, characterized in that a pressure water supply pipe cuts into the external and internal vacuum spaces, and a valve is installed in the discharge pipe.
