[0016] like Figure 1As shown, the utility model is a carboxy styrene butadiene latex filtering device, comprising a carboxy styrene butadiene latex storage tank 1 and a crane 2, and also comprising a delivery pump 3 and two basket filters 4 arranged in parallel, wherein the delivery pump 3 is arranged between the discharge end of the carboxy styrene butadiene latex storage tank 1 and the feed ends of the two basket filters 4, so as to deliver the carboxy styrene butadiene latex in the carboxy styrene butadiene latex storage tank 1 to the basket filters 4, and a feed control valve 5 is arranged on the feed side of each basket filter 4, and the discharge ends of the two basket filters 4 are connected to the crane 2. When working, firstly, the feed control valve on the feed side of one basket filter is opened, and the feed control valve on the feed side of the other basket filter is closed, and the delivery pump delivers the carboxy styrene butadiene latex in the carboxy styrene butadiene latex storage tank to the basket filter, and then the latex is delivered to the crane 3 after being filtered by the basket filter, and then pumped into the tank truck through the crane 3. When the filter screen of a normally working basket filter is clogged, open the feed control valve on the feed side of another basket filter to ensure that the loading process can proceed continuously, which can better improve the loading efficiency.

[0017] In this embodiment, the discharge end of the carboxy styrene butadiene latex storage tank 1 is connected to a discharge main pipe 6, and one end of the discharge main pipe 6 away from the carboxy styrene butadiene latex storage tank 1 is connected to two discharge branch pipes 7 arranged in parallel, and the two discharge branch pipes 7 are respectively connected to the feed ends of two basket filters 4; the conveying pump 3 is installed on the discharge main pipe 6 and is located between the carboxy styrene butadiene latex storage tank 1 and the two discharge branch pipes 7.

[0018] In this embodiment, the feed control valve 5 is installed on the discharge branch pipe 7 .

[0019] In this embodiment, for the convenience of control, the feed side and the output side of the delivery pump 3 are respectively provided with control valves 8 .

[0020] In this embodiment, it also includes a conveying main pipe 9 connected to the crane pipe 2, and two conveying branch pipes 10 arranged in parallel are connected to the conveying main pipe 9.
