Description

Sewage drainage package system preventing clogging by strainer chamber

The present invention relates to a sewage package system installed in a sewage tank to drain sewage.

In general, a sewage pump is installed in a sewage tank to discharge sewage to the outside through a discharge pipe.

The sewage pump discharges sewage in the form of rotating an impeller by a driving motor. In particular, various foreign substances such as toilet paper, hair, sanitary napkins, and wet tissues are mixed and flowed into the sewage tank of a building. There was a problem in that a failure occurred and maintenance was required frequently.

In order to solve this problem, Korean Patent Registration No. 10-2246436 (public notice 2021429) has previously disclosed a “sewage pump system equipped with a self-cleaning function”.

In the conventional sewage pump system equipped with the self-cleaning function described above, when a foreign substance is clogged in either pump A or pump B, the clogged foreign substance can be removed by pumping water from the unclogged counterpart for cleaning.

However, since the conventional sewage pump equipped with a self-cleaning function requires two pumps to be operated to prevent clogging of foreign substances, power consumption increases, and it is difficult to fundamentally block the inflow of foreign substances due to continuous foreign substances. There was a problem that clogging occurred and had to be repaired frequently.

In addition, another conventional Korea Patent Registration No. 10-2118685 (202063 announcement) "high pressure sewage pump system" has been disclosed. It was possible to prevent clogging by minimizing the inflow of foreign substances into the transfer pump by starting the transfer pump together.

However, other conventional high-pressure sewage pump systems also have problems in that the grinding pump and the transfer pump must be started at the same time, so the consumption cost increases, the installation space must be secured, and it is difficult to install in the existing sewage tank.

The present invention has been made to solve the above problems, and the problem to be solved by the present invention is a strainer that can minimize the occurrence of fixation due to clogging of the sewage pump by minimizing the inflow of foreign substances into the sewage pump by the strainer chamber An object of the present invention is to provide a sewage drainage package system preventing clogging by a chamber.

In addition, since only sewage is supplied to the sewage pump in the state in which foreign substances are filtered in the strainer chamber, and the sewage pump discharges sewage together with foreign substances, only one sewage pump can be started to discharge foreign substances while minimizing the inflow. It is an object of the present invention to provide a sewage drainage package system preventing clogging by a strainer chamber capable of reducing power consumption.

In addition, since the opening and closing member is lifted by sewage to operate the sewage pump, the structure is simplified to minimize the occurrence of malfunctions, and since only a strainer chamber and a sewage pump can be additionally installed in the existing sewage tank, it can be configured. It is an object of the present invention to provide a sewage drainage package system that prevents clogging by a strainer chamber that can be easily applied and installed.

In addition, when the sewage tank is at a full water level, the opening and closing member discharges the sewage while the sewage pipe is closed, thereby minimizing the frequent start-up of the sewage pump due to the continuous inflow of sewage, thereby preventing an increase in power consumption. It is an object of the present invention to provide a sewage drainage package system that prevents clogging by a strainer chamber.

In order to achieve the above object, a sewage package system preventing clogging by a strainer chamber according to an embodiment of the present invention includes a sewage tank for storing sewage, a sewage pump installed inside the sewage tank to suction and discharge sewage, and a strainer chamber for separating foreign substances from sewage flowing into the sewage tank, wherein the strainer chamber has a sewage inlet portion connected to a sewage pipe into which sewage flows from an upper portion of the strainer chamber, and a A strainer unit that filters out foreign substances contained and divides into a foreign substance space where the filtered foreign substances are located and a sewage space where the sewage filtered foreign substances are located. It flows into the sewage tank through and connects the discharge port of the sewage pump and the sewage space to drain the sewage in the sewage tank through the discharge port when the sewage pump is operated, and the outside of the sewage tank. and a discharge connector connecting the foreign matter space and a discharge pipe for discharging the sewage so that the sewage is discharged together with the foreign matter located in the foreign matter space.

The strainer chamber may include an opening and closing member that opens and closes the sewage inlet according to the water level in the strainer chamber.

The opening/closing member may include a pump switch for operating the sewage pump by the opening/closing member to drain sewage through the discharge pipe in a state in which the sewage inlet is closed.

The opening and closing member may be formed as a floating body to open and close the sewage inlet depending on the water level by being supported on the water surface of the strainer chamber.

The strainer unit discharges a part of the sewage discharged from the sewage pump to the lower portion of the opening and closing member to seal the sewage inlet even if the water level of the strainer chamber is lowered in a state in which the opening and closing member closes the sewage inlet. wealth may be included.

According to the present invention, the strainer chamber for filtering foreign substances is installed inside the sewage tank, and only the sewage filtered out of the foreign substances is supplied to the sewage pump. It is possible to minimize the occurrence of failure of the sewage pump due to foreign substances by blocking it at the source.

In addition, power consumption can be reduced because sewage is discharged together with foreign substances without clogging even with the operation of one sewage pump.

In addition, since the opening and closing member is lifted by sewage to operate the sewage pump, the structure can be simplified to minimize the occurrence of breakdowns. Since it can be configured by installing a strainer chamber and a sewage pump in the sewage tank, it is also suitable for existing sewage tanks. It has the advantage of being easy to apply and install.

In addition, when the sewage tank is full of water, since the opening and closing member discharges the sewage while the sewage pipe is closed, it is possible to prevent an increase in power consumption due to frequent start-up of the sewage pump due to the continuous inflow of sewage. .

In addition, since only the motor assembly is separated from the sewage pump, maintenance is easy.
