[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:
[0018] See attached Figure 1 To Attachment Figure 3 As shown, an iron-molybdenum catalyst uniform crushing device comprises a mounting frame 1, a crushing box 2 is arranged on the mounting frame 1, a feeding hopper 21, a qualified particle discharge pipe 22 and a coarse particle discharge pipe 23 are arranged on the crushing box 2; a crushing liner 3 is arranged in the crushing box 2, a crushing cavity (not shown) is arranged in the middle of the crushing liner 3, a discharge port 32 is connected to the bottom of the crushing cavity, a crushing roller 31 is arranged in the crushing cavity, the crushing roller 31 is in a truncated cone structure with a wide top and a narrow bottom, and the top of the crushing roller 31 is connected to a driving motor 34 arranged on the crushing box 2 so that the driving motor 34 can be driven by the crushing roller 31. The operation of the machine 34 causes the pulverizing roller 31 to rotate, and a pulverizing channel 33 with a decreasing opening and connected to the discharge port 32 is formed between the pulverizing roller 31 and the pulverizing liner 3, so that the iron-molybdenum catalyst can be discharged directly from the discharge port 32 after being pulverized; a screen 4 is also obliquely arranged in the pulverizing box 2, and the screen 4 is between the discharge port 32 and the particle discharge pipe, and the lower end of the screen 4 is connected to the coarse particle discharge pipe 23, so that particles that do not meet the particle size can be discharged through the coarse particle discharge pipe 23, and particles that meet the particle size can be discharged through the qualified particle discharge pipe 22.
[0019] During the specific implementation of the device, the iron-molybdenum catalyst is fed through the feed hopper 21 and then uniformly enters the crushing channel 33. As the crushing roller 31 rotates, the iron-molybdenum catalyst in the crushing channel 33 is crushed by the crushing roller 31 and the crushing liner 3. Since the diameter of the crushing channel 33 is set in a decreasing manner, the iron-molybdenum catalyst is crushed step by step, and the crushing is carried out continuously. The iron-molybdenum catalyst stays in the crushing channel 33 for a long time and has high uniformity after crushing. The iron-molybdenum catalyst that is crushed into particles falls from the discharge port 32 onto the screen 4 for particle size screening. Particles that do not meet the particle size are discharged through the coarse particle discharge pipe 23, and particles that meet the particle size are discharged through the qualified particle discharge pipe 22.
[0020] In order to allow the fed iron-molybdenum catalyst to be concentrated into the crushing channel 33, a feed ring 35 is provided in the crushing box 2. The feed ring 35 is located above the crushing roller 31 to prevent the iron-molybdenum catalyst from falling into the cavity between the crushing roller 31 and the top of the crushing box 2 when being fed.
[0021] In order to improve the feeding effect of the crushed iron-molybdenum catalyst, refer to the attached Figure 1 As shown, a material introduction ramp 5 is provided at the bottom of the crushing box 2. The material introduction ramp 5 decreases in height from the outside to the inside and forms a through opening connected to the qualified particle discharge pipe 22 at the lowest point.
[0022] Wherein, in order to improve the screening effect of the screen 4, refer to the attached Figure 4 As shown, the screen 4 is movably arranged in the crushing box 2 and connected to the vibration spring 41 arranged on the material introduction ramp 5. A vibration motor 42 is installed at the bottom of the screen 4 so that the vibration motor 42 operates to make the screen 4 vibrate.
