Description

Self-weight open and sealing type apparatus for foreign matter discharging capable of pressure maintaining}

The present invention relates to a self-weight opening and closing type pressure maintenance foreign material discharge device, and more particularly, to a self-weight opening and closing type pressure maintenance foreign material discharge device that improves the efficiency of collecting microplastics.

In recent years, millions of tons of plastics are introduced into the ocean every year worldwide, and plastics are decomposed into microplastics by weathering in the ocean, abrasion by waves, and ultraviolet radiation.

In particular, widespread plastic intake has been documented in birds and tortoises, with at least 44% of marine algae consuming plastics, such as the proven black-footed albatross (Phoebastria nigripes), which feeds chunks of plastic to its young.

Moreover, microplastics have the ability to adsorb, release and transport toxic substances such as POPs, and have been reported to be ingested by both vertebrates and invertebrates, and bioaccumulation is very likely to occur. Therefore, management of marine plastic waste is urgent.

In particular, there is a serious problem that the marine ecosystem around the beach is damaged as microplastics floating in the sea are stacked on the beach by algae or waves.

However, in the case of Korea, despite the serious level of microplastic pollution, there is no specific plan for the collection of microplastics stacked on the beach.

In order to solve this problem, conventionally, a self-loading opening/closing type pressure maintenance foreign substance discharging device has been disclosed that simultaneously sucks beach sand and microplastics, then redistributes the sand to the outside and collects microplastics.

However, in the conventional self-weight opening and closing type pressure maintenance foreign material discharging device, the moment one side of the self-weight opening/closing type pressure maintenance foreign material discharging device is temporarily opened for the re-discharging of sand, the pressure inside the vacuum suction passage is rapidly lowered, so that the vacuum suction power is lowered. there was

Korean Patent Registration No. 10-2304348

In order to solve the above problems, an object of the present invention is to provide a self-loading opening and closing type pressure-maintaining foreign material discharge device in which the efficiency of collecting microplastics is improved.

In order to solve the above problems, the present invention is a lower pipe portion provided so that the collection containing microplastics and sand is sucked; The upper side part is tangentially connected to the discharge end of the lower pipe part, the first cyclone body part is narrowed from the top to the bottom so that the microplastic is separated from the collection by the vortex, and the discharge pipe part is connected to the opened lower end part ; The inlet end is connected to the upper central discharge end of the first cyclone body part so that the microplastic is sucked by the suction upward flow by the vortex, and the discharge end to the vacuum suction motor for forming a vortex inside the first cyclone body part The upper pipe part is connected; A compartment chamber in which the upper central side surrounds and connects the lower end of the discharge pipe part and a hinge connection part is formed on one side of the lower outer edge so that the collection from which the microplastics are separated is discharged, and the microplastic is hinged by the weight of the collection a self-weight opening/closing part that is rotated and covered under the opened lower part of the compartment chamber so as to be selectively opened and includes a see-through closing valve whose central part is hingedly connected to the hinge connection part; and a negative pressure maintenance valve selectively opened and closed according to a pressure difference between the first cyclone body part and the compartment chamber.

Through the above solution means, the present invention provides the following effects.

First, while the sight-opening valve under the compartment chamber is intermittently opened by the weight of the collection from which the microplastic to be discharged is separated, the negative pressure maintenance valve automatically slides and seals the first cyclone body part by the pressure difference to close the first cyclone body part. Since the vacuum suction power is continuously maintained, the microplastic collection efficiency can be significantly improved.

Second, by the pressure difference between the atmospheric pressure inside the open compartment chamber and the vacuum pressure inside the first cyclone body part, the guide frame part of the negative pressure maintenance valve extended at a plurality of places with a collection flow interval slides along the inner wall of the discharge pipe part. Accordingly, since the plate part seals and covers the lower side of the discharge pipe part, the vacuum suction power can be stably maintained.

Third, as the weight and the cover part of the sight closing valve are hinged on one side and the other side around the hinge connection part on the lower edge of the compartment chamber, the cover part is automatically opened intermittently and automatically restored by the weight of the weight after opening. Since the lower part of the compartment chamber is sealed, work convenience can be improved.
