Description

[Detailed description of the invention] [Industrial application field] This invention is a water tank that requires dustproofing, in which equipment installed in the tank passes through a groove in the upper wall of the tank and is attached to a moving device on the tank. This relates to a dustproof device for an aquarium when it is connected and moved back and forth.

[Prior Art] Conventionally, in this type of aquarium, the moving device on the aquarium and the equipment inside the aquarium are connected by an intermediate shaft passing through the slot, so the slot is always open, and from there the inside of the aquarium is connected. The problem was that dust could get inside.

[Problem to be solved by the invention] The problem of the invention is to open a slot only in the part through which an intermediate mechanism such as an intermediate shaft for moving equipment in the water tank passes, and to close the other part to prevent dust from entering the tank. The goal is to make sure that there is no such thing.

[Means for Solving the Problems] The means of the present invention is to provide an intermediate mechanism that connects the equipment installed on the moving device installed above the aquarium and the equipment inside the aquarium by using a slot formed in the slab of the upper wall of the aquarium. A dustproof curtain with a fastener is installed to cover the slot, and a pair of sliders that open the fastener only at the intermediate mechanism are attached oppositely to each other on the lower surface of the moving device before and after the intermediate mechanism. That's what happened.

[Example] The drawing shows a water tank dust prevention device equipped with the mobile device of the present invention implemented in a water purification tank of a rapid filtration tank, in which 1 is a raw water culvert, 2 is a filtration pond, and 3 is a water purification tank. Raw water in the raw water conduit 1 flows into the filter basin 2 through the distribution hole 4.

A filter medium 5 is provided in the filtration basin 2, and a water purification chamber 6 is formed below it, which communicates with the water purification tank 3 through a water purification hole 7, and the purified water filtered by the filter medium 5 of the filtration basin 2 is sent to the water purification chamber. 6. The water passes through the communication hole 7 and flows into the water purification tank 3, where it is stored and supplied as drinking water.

Since the filter medium 5 becomes clogged over time, it is necessary to restore the filtering function by backwashing. Therefore, rails 9 are laid on the slab, and a trolley 11 equipped with a cleaning device is installed.

12 indicates a backwash pump of the cleaning device, and the trolley 11
An intermediate shaft 14 from the upper electric motor 13 passes through a slot 15 in the upper wall of the slab to communicate with the backwash pump 12.

The slot 15 is a dustproof curtain 1 equipped with a fastener 16.
7, the intermediate shaft 14 and the protective outer cylinder 1 around it.
8 is passed through the opening of the fastener 16, and a pair of opposing fastener opening/closing sliders 19 and 20, which are attached to the lower side of the truck 11, are positioned before and behind the fastener 8. In the figure, reference numeral 21 indicates an indicator metal fitting fixed to the ring portions of the sliders 19 and 20 so that the slider moves forward and backward at the same time as the cart.
Therefore, the fastener 16 between the sliders 19 and 20
is always open, and the other parts are always closed. 22 is a purified water collection pipe led out from the backwash pump 12 and reaches a backwash valve 23. Reference numeral 24 denotes a discharge pump for discharging wastewater from which the filter medium 5 has been washed with water from the backwash valve 23, and the wastewater is discharged through a delivery pipe 25 to a drainage gutter 26.

[Function] As the truck 11 moves, the intermediate shaft 14 and the protective outer cylinder 18 move together. At that time, a pair of sliders 1
At 9 and 20, the fastener 16 is always opened by a certain distance, and the other parts are closed, and the intermediate shaft and protective outer cylinder located between both sliders push the fastener outward and move without any trouble, preventing dust from entering the water purification tank. be able to.

[Effects] According to the present invention, the fastener is opened only in a small part of the intermediate shaft that connects to equipment in the cleaning water tank such as a backwash pump, and all other parts are closed, so dust can be removed from the groove into the water purification tank. The opening part of the fastener is always under the trolley, so it is covered and dust-proofed by the trolley.
