[0006] The inner plate assembly includes an inner plate inserted into the anti-slip boss, one side of the inner plate is fixedly connected to an inner blind plate, a PTFE pad is sleeved on the surface of the inner plate, the other side of the inner plate is fixedly connected to a bearing seat, and the inside of the bearing seat is rotatably connected to a screw via a bearing.

[0007] Preferably, the tightening assembly comprises a sleeve threadedly connected to the surface of the screw, and push rods are fixedly connected to both sides of the sleeve.

[0008] Preferably, a slot is provided at one end of the screw rod, and a knob is clamped inside the slot.

[0010] Preferably, the push rod is inserted into the limiting groove.

[0011] Preferably, a buffer recess is provided on one side of the inner blind plate.

[0012] The utility model provides an anti-drop structure at the end of an acid distributor branch pipe, which has the following beneficial effects:

[0013] When in use, the inner plate is pulled from the branch pipe body to one end of the branch pipe body, and then the sleeve is screwed in and the push rod is inserted into the inside of the limit groove, and the knob is turned to support the screw rod through the push rod and make the anti-slip boss and the inner blind plate tightly abut, and the tight abutment point is sealed with a polytetrafluoro pad, and then the anti-slip boss and the inner plate can be welded, and the push rod and the knob can be removed after welding to avoid corrosion of the welding point due to the infiltration of sulfuric acid during subsequent use, which may cause sulfuric acid leakage, thereby improving the safety of the acid separation equipment during use.
