Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically a quick-release device for a belt conveyor at the bottom of an ammonium nitrate plant tower. Background Technology

[0002] Belt conveyors, also known as belt conveyors, are friction-driven machines that transport materials continuously. In the production of ammonium nitrate, the bottom belt conveyor is responsible for transporting high-temperature, moisture-absorbing, and caking ammonium nitrate materials. Due to the special properties of the materials, belt conveyors often require quick disassembly and replacement of the belts.

[0003] However, in the existing technology, the quick-release device for the bottom belt conveyor of the tower usually requires manual replacement and disassembly of the belt. This not only increases the labor intensity of manual labor, but also greatly reduces the efficiency of quick-release and replacement. Therefore, we propose a quick-release device for the bottom belt conveyor of the ammonium nitrate plant. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a quick-release device for a belt conveyor at the bottom of an ammonium nitrate plant. The device utilizes a second drive assembly to rotate a second shaft, which in turn rotates a belt winding roller. This rotation of the belt winding roller causes the belt to move, slowly winding it around the roller. The belt movement then drives the conveyor belt (a new belt). When the connection between the belt and the old belt is above the second tension roller, the second drive assembly is closed, disassembling the connection between the belt and the old belt. The old belt of the conveyor is placed on the frame. Then, the outer end of the old belt is connected to the left end of the old belt, and the outer end of the new belt is connected to... The right end of the old belt of the belt conveyor is connected. Then, the second drive assembly is started again. The second drive assembly drives the belt pulling motion, which in turn drives the old belt, which in turn drives the new belt, so that the new belt replaces the old belt and is put onto the belt conveyor. After the belt pulling is tightened, the second drive assembly is turned off, and the left end of the old belt of the belt conveyor is connected to the old belt on the old belt winding roller. Then, the first drive assembly is started to continue to realize the quick disassembly and replacement of the belt conveyor. This device not only reduces the labor intensity of manual labor, but also improves the efficiency of quick disassembly and replacement of the belt conveyor, which can effectively solve the problems in the background technology.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-2 This embodiment provides a technical solution: a quick-release device for a belt conveyor at the bottom of an ammonium nitrate plant, comprising a base plate 1, a frame assembly, a first drive assembly, and a second drive assembly; The base plate 1 is located inside the frame assembly.

[0020] The working principle of the quick-release device for the bottom belt conveyor of an ammonium nitrate plant provided by this utility model is as follows: In use, firstly, the second drive assembly drives the second rotating shaft to rotate.
