Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1, 2 and 3, the utility model discloses can improve an embodiment of the tank filter of airtight effect, be applicable to a filter tank 1, the tank filter that can improve airtight effect contains a apron 2, a filter vat 3, a pump 4, a sealing member 5 and a plurality of lock solid unit 6. The filter tank 1 is used for placing chemical waste liquid 9, and in this embodiment, the chemical waste liquid 9 is a strong acid liquid which is easy to generate acid waste gas.

Referring to fig. 2, 3 and 4, the cover plate 2 is covered on the filter tank 1, and includes a cover plate body 21, a first mounting hole 22 penetrating the cover plate body 21 along an axis L, a second mounting hole 23 penetrating the cover plate body 21 and spaced from the first mounting hole 22, and a plurality of fixing portions 24 disposed at intervals on the cover plate body 21 and adjacent to the first mounting hole 22. In this embodiment, each fixing portion 24 is formed with a blind hole 241 with an upward opening, and the blind hole 241 is not connected to the filter tank 1, so as to isolate the chemical waste liquid 9 from the acidic waste gas.

The filtering barrel 3 is arranged in the filtering tank 1 and penetrates through and seals the first mounting opening 22 along the axis L. The filtering barrel 3 comprises a filtering barrel body 31, a connecting port 32 arranged on the filtering barrel body 31, a convex ring 33 convexly arranged on the peripheral surface of the filtering barrel body 3, a ring groove 34 concavely arranged on the convex ring 33, and a plurality of lugs 35 arranged on the peripheral surface of the filtering barrel body 31 at intervals around the axis L. The lugs 35 are respectively located corresponding to the fixing portions 24, and each lug 35 has a locking hole 351.

The pump 4 is disposed in the filter tank 1 and closes the second mounting port 23 of the cover plate 2. The pump 4 includes a first portion 41 disposed above the second mounting port 23, and a second portion 42 connected to the first portion 41 and disposed below the second mounting port 23, wherein the second portion 42 is connected to the connection port 32 of the filter vat 3.
