Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for collecting, storing, and detoxifying batteries such as dry cells that are contaminated with harmful substances such as mercury.

With the increase in the number of portable electrical appliances, the consumption of dry batteries, mercury batteries, etc. is rapidly increasing, and waste management is becoming an important issue. Because these batteries are difficult to crush due to their structure, used batteries are collected in general trash cans or special containers, and then landfilled. However, batteries contain trace amounts of harmful substances such as mercury, so if today's mass consumption continues, large amounts of harmful substances will flow out of landfills and pose a risk to the human body. It is clear from experience that this will happen. Therefore, it is necessary to collect and store batteries in a specific container, detoxify them, and then send them for recycling or landfill. However, it is extremely difficult logistically to collect and store a large number of used batteries that are used and scattered everywhere, and there are also problems such as sensible heat due to residual electricity and the spread of leakage. Since then, it has been considered technically difficult.

The present invention has been made in view of the above points, and an object of the present invention is to provide a processing and storage device that can safely collect and store waste batteries and remove harmful substances such as mercury generated during storage. It is about providing.

Another object of the present invention is to provide a processing and storage device that can safely collect, transport, and recycle batteries after storage.

The processing and storage device for waste batteries according to the present invention includes a container for accommodating batteries containing harmful substances such as mercury, a battery receiving part provided in the container, and a suction unit for sucking harmful substances such as mercury present in the container. a suction device for removing air, a filter and a device for adsorbing harmful substances such as mercury, which are arranged in a path through which the air sucked by the suction device passes, and an exhaust section for discharging the air after passing through the suction device to the outside of the container. It is characterized by

From the perspective of improving the efficiency of the logistics system of waste treatment, the device of the present invention is connected to a crushing device for glass appliances such as waste fluorescent lamps that similarly contain harmful substances such as mercury, and a single suction device can handle both types of equipment. Preferably, the processing device is configured to draw air from the processing device.

Preferably, the container is made of a container whose lower part is removable for transporting the accumulated material, such as a regular container such as a drum or a pail.

The device of the present invention can be implemented in various ways depending on the size and shape of the object to be collected, such as when the object to be collected is a primary battery, a secondary battery, or a mixture of both. .

Other objects, features and advantages of the invention will become apparent from the following description with reference to the embodiments of the accompanying drawings.

FIG. 1 shows the basic system of the waste battery processing and storage apparatus according to the present invention, in which a lid 12 with an airtight seal provided on a receiving part 11 of a container 10 for storing batteries is opened and the inside of the container 10 is opened. Insert battery B into the When a large amount of batteries accumulate, sensible heat is generated in the container 10 due to the amount of residual electricity, necessitating ventilation for cooling. In addition, batteries that begin to leak waste fluid emit mercury vapor and other harmful substances that can fill the container in suspension.

In the present invention, these are sucked by a suction device 20, such as a fan or a blower. A filter 21 for removing dust and a gas-type, liquid-type, or solid-type mercury and other hazardous substance adsorption device 22 containing activated carbon, chelate resin, etc. that adsorb mercury are arranged in the suction air passage 23. . The clean air that has passed through the suction device 20 is discharged from the exhaust section 24 in the direction of arrow E.

The suction device 20 includes a filter 21 and an adsorption device 22
It can also be placed somewhere in between.

If the lower part 28 of the container 10 is sealed with the upper part and made removable, when batteries are accumulated, it can be removed, covered with an airtight cover, and transported to a recycling factory. I can do it.
It is desirable that the lower portion 28 be replaced by a regular container such as a drum or a pail.

In order to prevent fine powder from scattering at the moment of removing the lower portion 28, it is desirable to operate the suction device 20 for a certain period of time immediately before removing the lower portion 28.

The suction device 20 is driven by a battery (not shown) installed in the processing and storage device or by an external power source.

The embodiment shown in FIG. 2 is intended to improve the efficiency of the distribution system by connecting the basic system of the present invention with a waste fluorescent lamp crushing device 30. In the figure, an entrance door 32 of a receiving guide tube 31 for a fluorescent lamp G is shown.
After opening the guide tube 31 and putting an appropriate number of fluorescent lamps into the guide tube 31, the entrance door is closed. Next, when the operating means such as the foot pedal 33 provided on the outside of the frame is moved, the guide tube 31 is lifted in the direction of arrow C by the link mechanism, and the fluorescent lamp inside moves in the direction of arrow D due to its own weight, and the center part It falls towards the crushing device 35. The fragments after crushing are stored in drum container 3.
6, and are accumulated and stored.

As is well known, glass appliances such as fluorescent lamps, thermometers, and mercury lamps contain trace amounts of harmful substances such as mercury. It is necessary to carry out suction treatment. Thus, as shown in FIG. 2, the air inside can be sucked from the side of the crushing device 35 by the suction device 20 via the suction pipe 23.

Waste batteries, which are the main treatment target of this invention, are similar to waste fluorescent materials in that they contain harmful substances such as mercury, and by collecting and storing both at the same time, we can prevent the spread of pollution and create a logistics system. efficiency will be further increased.

According to the present invention, waste batteries can be safely collected and stored, and heat and harmful substances generated during storage can be removed, thereby helping to prevent pollution.
In addition, the effects of the treatment are extremely remarkable, such as the ability to use the treated batteries for recycling.
