[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] As Figure 1 shown, a filter tank for the production of n-butyl acrylate includes a tank body 1, a cover plate 2 is arranged above the tank body, a first filtering structure and a second filtering structure are arranged in the tank body. Specifically, the first filtering structure includes a frame 3, a cross plate is arranged on the lower end surface of the frame, filter holes are arranged on the cross plate, a first filter cloth is arranged on the cross plate, and the first filter cloth can be arranged by extruding the outer edge of the filter cloth through a separately arranged positioning plate. The second filtering structure includes a second frame 4, a plurality of flow guiding structures are arranged below the second frame, the flow guiding structures include an enclosing plate 5, the inner diameter of the enclosing plate gradually decreases from top to bottom, a second filter cloth is arranged in the enclosing plate, a fixed pipe 8 is arranged below the enclosing plate, an activated carbon adsorbent is arranged in the fixed pipe, a fixing plate is arranged at the lower end of the fixed pipe, and holes are arranged on the fixing plate. A feed inlet is arranged on the cover plate, and a discharge outlet is arranged at the lower end of the tank body.

[0017] Furthermore, the second frame and the flow guiding structure are integrally formed, and a plurality of flow guiding structures cover the lower end surface of the second frame. Ensure the comprehensiveness and effectiveness of secondary filtration.

[0018] An annular protruding portion 6 is provided inside the enclosing plate. The outer edge of the second filter cloth is disposed on the protruding portion. A pressing plate 7 is further connected to the second frame. An extrusion member for extending into the enclosing plate to press the second filter cloth is provided on the pressing plate. The extrusion member includes a plurality of hollow cylindrical plates, and the cylindrical plates can also be provided with holes. The connection between the pressing plate and the second frame can be achieved by bolts.

[0019] A flow guide plate 9 is provided above the first filtering structure. There are two groups of flow guide plates, which are disposed obliquely downward and are respectively disposed on both sides inside the tank body. Fixing holes are provided on the flow guide plate. To prevent the incoming liquid from directly impacting the first filter cloth, protect the first filtering structure and thus ensure the filtering effect.

[0020] Furthermore, the flow guide plate and the first filtering structure are disposed on a fixing frame, and the fixing frame is slidably connected to the side wall of the tank body up and down.
