[0021] See also Figure 1-6 , the embodiment of the present application provides a technical solution: to solve the above technical problems, the utility model provides a bottom filtering structure of a vertical filter, including a collecting box 100 and a feed port 200 and a discharge port 300 arranged on the collecting box 100, a plurality of slots 110 are arranged on one side wall of the collecting box 100, a support plate 120 flush with the lower surface of the slots 110 is arranged on the inner wall of the collecting box 100, a flat plate 400 with a width consistent with the width of the slots 110 is arranged on the support plate 120, a plurality of small holes are arranged on the flat plate 400, a microporous filter plate is fixed on the upper surface of the flat plate 400, and the flat plate 400 and the microporous filter plate as a whole can be pulled out of the collecting box 100 along the slots 110.

[0022] The feed port 200 is used to be connected and fixed to the filtrate collecting pipe. The liquid flowing out of the filtrate collecting pipe enters the collecting box 100 from the feed port 200. The discharge port 300 is used to be connected to other pipelines.

[0023] By separately arranging the filtrate collecting pipe and the microporous filter plate arranged below the filtrate collecting pipe, when there are too many filter cakes on the microporous filter plate, the microporous filter plate can be pulled out as a whole, and then the microporous filter plate can be turned upside down, or air can be blown from top to bottom to let the filter cakes enter the collection bag, which can be an ordinary garbage bag or nylon bag, etc. In this way, all the filter cakes are effectively collected, and by arranging the removable flat plate 400 and the microporous filter plate, it is easier to collect the filter cakes.

[0024] Preferably, the cross section of the collection box 100 is rectangular, the width of the slot 110 is equal to the width of the collection box 100 in the same direction, and the support plates 120 are symmetrically arranged inside the collection box 100 .

[0025] Preferably, a first side wall 411 and a second side wall 416 are upwardly arranged around the flat plate 400 .

[0026] The first side wall 411 and the second side wall 416 have a certain height.

[0027] Preferably, a baffle 412 is provided on the second side wall 416 , and a size of the baffle 412 is larger than a cross-sectional size of the slot 110 .

[0028] The baffle 412 having a cross-sectional size larger than the slot 110 is provided to play a blocking role when the flat plate 400 is pushed into the slot 110 , and the baffle 412 can completely cover the slot 110 .

[0029] Preferably, a sealing gasket 413 is disposed on the baffle 412 , and the sealing gasket 413 surrounds the second side wall 416 .

[0030] The sealing gasket 413 may be glued together with the baffle 412 .

[0031] Preferably, a drawer lock 414 is also provided on the baffle 412, and a groove 418 corresponding to the lock body is provided on the side wall of the collection box 100.

[0032] The drawer lock 414 is a common drawer lock on furniture, which is more common in life. The locking principle of the drawer lock 414 is that after the baffle 412 is pushed into place, the drawer lock is turned by the key, and a card block extends from the inside of the drawer lock and is stuck on the inner wall of the collection box, so that the tablet 400 cannot be drawn out. The card block is retracted by turning the key in the reverse direction, and the tablet 400 can be drawn out.

[0033] Preferably, a protrusion (122) is further provided on one side of the support plate 120, and a corresponding recessed groove 417 is provided on the corresponding flat plate 400. A protrusion is also provided at the corresponding position of the collection box 100, and this protrusion corresponds to the protrusion (122) on the support plate 120, so that the whole can be pulled out without lifting it upward at an angle.

[0034] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
