Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical raw material processing equipment, in particular to a raw material processing device. Background Technique
[0002] 4-Dimethylaminopyridine is a new type of highly efficient catalyst widely used in chemical synthesis. It is a white crystalline powder with the molecular formula C7H 10 N2. It is a super strong nucleophilic acylation catalyst. Its production process involves steps such as raw material pretreatment, rinsing hydrolysis, extraction, drying, and concentration crystallization. Among them, raw material pretreatment mainly includes screening and purification to ensure the quality of raw materials and meet the requirements of subsequent production. In actual production, raw materials often get damp and caked. For those with serious dampness and large caked lumps, they cannot be used continuously and need to be screened out. For raw materials with less dampness and smaller caked lumps, they can be used continuously after treatment. At present, in the production process, screening and subsequent treatment are carried out in two steps, with low efficiency and high equipment cost. The screening device often adopts a "one-size-fits-all" form and does not screen the raw materials carefully, resulting in no targeted treatment for subsequent treatment. For raw materials with less dampness and smaller caked lumps that can be used continuously, the treatment effect is not good, and the treatment is prone to waste and low efficiency. Therefore, further improvement is needed. Summary of the Utility Model
[0003] Aiming at the above technical problems, the utility model provides an efficient processing device that can perform targeted treatment on raw materials.
[0004] To solve the above technical problems, a raw material processing device described in the utility model includes a frame. A screening cylinder is rotatably connected to the top of the frame in an inclined manner. A feed hopper is arranged on the frame at the higher side of the screening cylinder, and a discharge hopper is arranged on the frame at the lower side of the screening cylinder. The screening holes on the higher side of the screening cylinder are smaller than those on the lower side. A fine material channel is arranged below the smaller screening holes of the screening cylinder, and a coarse material channel is arranged below the larger screening holes of the screening cylinder. The fine material channel and the coarse material channel are fixedly connected to the frame. Two crushing rollers are rotatably connected in the coarse material channel. The bottoms of the fine material channel and the coarse material channel are communicated and fixedly connected with a screw conveyor. The screening cylinder is driven by a screening cylinder motor, the crushing rollers are driven by a crushing roller motor, and the screw conveyor is driven by a screw conveyor motor. Support legs are fixedly connected around the frame.
[0005] Further, the feed hopper and the discharge hopper are fixedly connected to the frame along the inclined direction of the screening cylinder.
[0006] Further, the screening cylinder motor, the crushing roller motor, and the screw conveyor motor are all controlled by a controller.
[0007] The utility model has the following advantages compared with the prior art:
[0008] The utility model screens the raw materials in three levels through a two-stage sieve barrel with different-sized sieve holes, screens out the unusable large lumps affected by moisture, crushes the slightly moisture-affected lumps that can be used, and mixes and conveys them with normal raw materials through a screw conveyor, achieving integrated processing; by screening out the fine materials in advance and only targeting the crushing of the raw materials with slightly moisture-affected lumps, the crushing efficiency is improved, the efficiency of raw material pretreatment is further increased, the cost investment of the equipment is reduced, and at the same time, the raw materials are processed in a targeted manner, the utilization efficiency of the raw materials is improved, and unnecessary waste is avoided.

[0013] The following further explains the utility model in conjunction with the description of the drawings.
[0014] As Figures 1 to 3 shown, a raw material processing device includes a frame 1. The top of the frame 1 is rotatably connected to a sieve barrel 2 in an inclined manner through bearings. A feed hopper 3 is fixedly connected to the frame 1 on the higher side of the sieve barrel 2, and a discharge hopper 4 is fixedly connected to the frame 1 on the lower side of the sieve barrel 2. The sieve holes on the higher side of the sieve barrel 2 are smaller than those on the lower side. A fine material channel 6 is arranged below the smaller sieve holes of the sieve barrel 2, and a coarse material channel 5 is arranged below the larger sieve holes of the sieve barrel 2. The fine material channel 6 and the coarse material channel 5 are fixedly connected to the frame 1. Two crushing rollers 7 are rotatably connected in the coarse material channel 5, and the two crushing rollers 7 are drivingly connected in a gear engagement form. The bottoms of the fine material channel 6 and the coarse material channel 7 are communicated and fixedly connected to a screw conveyor 8. The sieve barrel 2 is driven by a sieve barrel motor 9, the crushing rollers 7 are driven by a crushing roller motor, and the screw conveyor 8 is driven by a screw conveyor motor 10. Support legs 11 are fixedly connected around the frame 1.
[0015] For the convenience of the entry and exit of raw materials, the feed hopper 3 and the discharge hopper 4 are fixedly connected to the frame 1 along the inclined direction of the sieve barrel 2.
[0016] For the convenience of control during operation, the sieve barrel motor 9, the crushing roller motor, and the screw conveyor motor 10 are all controlled by a controller.
[0017] The working process of this embodiment is as follows:
[0018] Start the screen cylinder motor 9, the crushing roller motor, and the auger motor 10 through the controller. Subsequently, add the raw materials into the screen cylinder 2 through the feed hopper 3. The raw materials with smaller particles fall into the fine material channel 6 through the mesh holes at the higher end of the screen cylinder 2, and the slightly caked raw materials fall into the coarse material channel 5 through the part with larger mesh holes on the screen cylinder 2. Subsequently, they are crushed by the crushing roller 7 and merged with the fine materials, and finally conveyed out by the auger 8. The severely damp and large-caked parts are output from the discharge hopper 4 and are centrally disposed of later. By screening out the fine materials in advance and only performing targeted crushing on the slightly damp and caked raw materials, the crushing efficiency is improved, the raw material pretreatment efficiency is further improved, the equipment cost investment is reduced, and at the same time, the raw materials are treated in a targeted manner, the utilization efficiency of the raw materials is improved, and unnecessary waste is avoided.
