A feed port 11 is arranged on one side of the sludge dewatering performance testing device body 1. Fixed mounting plates 3 are installed on one side of the sludge dewatering performance testing device body 1 and at both ends of the feed port 11. The sludge dewatering performance testing device body 1 is an existing structure and technology, so the technical scheme will not be elaborated on. The connection method between the sludge dewatering performance testing device body 1 and the feed port 11 is also an existing structure and technology, so the technical scheme will not be elaborated on.

[0022] At the same time, a slide groove is opened on the side of the collection box 2 away from the discharge port 11, and a limit baffle 22 is slidably installed in the slide groove. A through hole is opened in the lower middle part of the side of the collection box 2 away from the discharge port 11, and a placement cavity is opened in the middle of the top of the collection box 2. A guide plate 24 is installed in the lower middle part of the side close to the discharge port 11 in the placement cavity through a rotating shaft.

[0023] In addition, a fixed baffle 27 is installed above the corresponding guide plate 24 on the side of the cavity close to the discharge port 11, and the top of the fixed baffle 27 is inclined toward the side of the through hole, wherein the sludge is guided by the fixed baffle 27 to ensure that the sludge falls into the top of the guide plate 24 along the fixed baffle 27.

[0024] Furthermore, fixed slide bars 23 are installed in the upper middle part of both sides of the collecting box body 2, and limiting slide grooves 31 are provided in the fixed mounting plate 3 at the corresponding fixed slide bars 23, wherein the collecting box body 2 is limited by the fixed mounting plate 3 and the limiting slide grooves 31 to ensure that the collecting box body 2 is always located at the corresponding discharge port 11.

[0025] In addition, universal wheels 21 are installed around the bottom of the collection box 2, and a handle portion 25 is installed on the upper middle part of the side of the collection box 2 away from the discharge port 11, wherein the universal wheel 21 has a self-locking structure. When the collection box 2 is moved to a suitable position, the universal wheel is self-locking, and the handle portion 25 is used to facilitate the user to move the collection box 2.

[0026] At the same time, a handle is provided in the middle of the side of the limit baffle 22 away from the discharge port 11, and a fixed shaft is installed on the top of the through hole of the collecting box body 2 on the side of the corresponding handle, and a fixed block is installed on the bottom of the fixed shaft, and a limiting plate 28 is provided on the outer sleeve of the fixed shaft, wherein the handle of the limit baffle 22 is limited by the limiting plate 28, and then the limit baffle 22 is limited.
