Impurity removal equipment for vacuum drainage system

Abstract

The invention relates to impurity removal equipment for a vacuum drainage system. The impurity removal equipment comprises a vacuum tank body 2 and an impurity storage tank 6, wherein an inlet pipe 1is arranged on the upper side of the vacuum tank body 2, and a fourth valve 11 is installed on the top of the vacuum tank body 2; one end of a first valve 3 is connected with a hose 4, the other end of the first valve 3 is fixed to the vacuum tank body 2, a partition 9 is arranged in the vacuum tank body 2, and the top of the impurity storage tank 6 is connected with the bottom of the vacuum tankbody 2 through a second valve 5; and a third valve 7 is arranged at the bottom of the impurity storage tank 6. According to the device, large and hard substances introduced into the vacuum drainage system due to unconventional operation can be effectively removed, such as keys, coins, miscellaneous stones, bolts, nuts, welding slag during pipeline welding and the like; the condition that the system cannot be operated because a sewage pump sucks the substances and is damaged is effectively prevented; and shutdown is not needed when impurities are removed by the system, and additionally, the tank body can be used as an energy storage device of the system, so that the stable operation of the system is facilitated.

Description

technical field [0001] The invention belongs to the technical field of ship sewage treatment, and in particular relates to an impurity removal device for a vacuum drainage system. Background technique [0002] Vacuum collection technology utilizes the concept of vacuum in physics, and uses the pressure difference between vacuum and normal pressure as the power source for transmission to realize the collection and transportation of objects. After more than 100 years of development, vacuum collection technology has been successfully widely used in indoor sewage discharge, outdoor drainage, mobile toilets, urban garbage collection and other fields. [0003] The vacuum drainage system uses vacuum as power to transport the dirt, in which the water mainly plays the role of lubricating the pipe wall, reducing the transportation resistance, and has the outstanding advantages of saving water. In addition, it has the advantages of convenient laying of the pipe network, small excavatio...

Problems solved by technology

However, there will always be pump damage during use

The damage of the pump is not a quality problem of the pump, but due to human reasons, the substances that should not appear cause the damage of the pump, which leads to the paralysis of the system
