Material delivery pump

Abstract

The invention provides a material delivery pump with a good using effect and long service life, comprising a storage jar, wherein, a feed inlet is opened at the upper part of the left part of the storage jar; the feed inlet is tightly connected with a feed delivery pipe; the feed inlet is installed with a feed knife switch valve; the other end of the material delivery pipe is connected with a feeding hose; a discharge hole is opened at the lower part of the right part of the storage jar; the discharge hole is installed with a discharging knife switch valve; the discharge hole is tightly connected with a discharge hose; the material delivery pipe and the discharge hose are respectively communicated with the storage jar; the storage jar is connected with a control system and is opened with ahigh pressure air inlet which is tightly connected with a vacuum generator; the vacuum generator is communicated with a storage jar; an air inlet pipe of the vacuum generator is connected with the high pressure air; an air outlet pipe of the vacuum generator is fixedly connected and communicated with the discharge hole; and the control system controls the feed knife switch valve and the discharging knife switch valve respectively through loading and discharging a timer.

Description

technical field [0001] The invention relates to an environment-friendly dredging equipment, in particular to a material conveying pump. Background technique [0002] In recent years, the state has increased investment to control environmental pollution, improve the living environment of residents, and protect the environment has become the theme of our lives. In the early stage, we conducted a social survey on the discharge and treatment of silt and industrial waste in industries such as the Yellow River silt, municipal sewage discharge, clear river treatment, coal mines, and metal mines. According to the social survey, we learned that the current domestic traditional mud and sediment There are two ways to deal with it, one is to rely on dredgers, and the other is to rely on mud pumps. For dredgers, due to the high cost and the inability to use them in a narrow environment, etc., they are used less; mud pumps are relatively widely used, and the equipment is relatively simpl...

AI Technical Summary

Problems solved by technology

For dredgers, due to the high cost and the inability to use them in a narrow environment, etc., they are used less; mud pumps are relatively widely used, and the equipment is relatively simple. It drives the impeller to rotate through the rotation of the motor, thereby generating centrifugal force. When the material is sucked in, during the rotation of the impeller, the sand directly contacts the impeller and collides with it at a high speed, so the impeller is seriously damaged and needs to be replaced once in less than half a month, and the efficiency is very low. In addition, during operation, Due to the high speed of the motor, the damage of the bearing is also very serious, the seal of the water retaining plate is not good, and the sediment often enters the motor, so the friction often causes the motor to heat up, and the service life of the machine is relatively short.

In addition, in terms of municipal dredging, the traditional dredging method completely relies on manpower, which has many unsafe hidden dangers and pollutes the environment.
