[0016] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0017] In an embodiment of the present utility model, Figure 1 , Figure 2 and Figure 3 It is a structural schematic diagram provided according to the specific structure of the utility model, such as Figure 1 As shown, the utility model specifically comprises: a mounting plate 1 and a collecting pipe 3, wherein the mounting plate 1 is detachably connected to the pulping nozzle 4.

[0018] like Figure 2 As shown, the mounting plate 1 is provided with a plurality of through holes 2 corresponding to the positions of the pulp outlet holes of the pulping nozzle 4, and a collecting pipe 3 is installed in each of the through holes 2.

[0019] like Figure 3 As shown, the outer diameter of the top opening of the collecting pipe 3 is greater than the diameter of the through hole 2 and greater than or equal to the diameter of the pulp outlet hole of the pulping nozzle 4, and the pipe body of the collecting pipe 3 passes through the through hole 2. Specifically, the outer diameter of the pipe body of the collecting pipe 3 is less than or equal to the diameter of the through hole 2.

[0020] Several circular through holes are opened on the mounting plate, and the diameter of the through holes is slightly larger than the outer diameter of the collecting tube body and smaller than the outer diameter of the collecting tube mouth, so that the collecting tube can be placed in the through holes and will not fall out of the through holes. The position and number of the through holes on the mounting plate correspond to the slurry outlet holes on the beating nozzle, and the outer diameter of the top opening of the collecting tube 3 needs to be slightly larger than the diameter of the slurry outlet holes, so that the slurry can smoothly enter the collecting tube. When testing, the mounting plate, the collecting tube and the beating nozzle can be connected.

[0021] In one embodiment of the utility model, a plurality of positioning holes are arranged around the mounting plate 1, and the mounting plate 1 is fixed to the beating nozzle 4 by means of bolts 5 passing through the beating nozzle 4 and the positioning holes.

[0022] In one embodiment of the present invention, the shape of the mounting plate 1 is the same as the shape of the beating nozzle 4. More specifically, the shape of the mounting plate 1 may be circular.

[0023] In one embodiment of the utility model, a weighing device is further included, and the weighing device is used to weigh each collecting tube 3. The weighing device can be an electronic scale. By determining the weight of each collecting tube 3 through the weighing device, the slurry discharge amount of each slurry discharge hole can be accurately determined.

[0024] In one embodiment of the utility model, the collecting tube 3 is made of a transparent material and has scale lines on the tube wall. For slurry with good fluidity, the amount of slurry in the tube can be checked through the scale lines on the tube wall to determine the slurry discharge amount of each slurry discharge hole, which can reduce the weighing process.

[0025] The use process of the utility model is as follows: during inspection, the collecting tube 3 is matched one by one with the pulping hole of the pulping nozzle 4, and the mounting plate 1 and the pulping nozzle 4 are connected together by locking bolts and locking nuts, so that the mouth of the collecting tube 3 fits with the pulping hole of the pulping nozzle 4.

[0026] After completing a pulping operation, remove the locking bolts and locking nuts, take down the mounting plate 1 and the collecting tube 3, weigh each collecting tube 1, and calculate the pulp discharge weight of each pulp outlet hole of the pulping nozzle 4. Through data analysis, verify the uniformity of the pulp discharge of the pulping nozzle 4.

[0027] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
