Description

Technical Field

[0001] The utility model relates to the technical field of unburned cement processing, in particular to phosphogypsum unburned cement equipment. Background Art

[0002] After certain treatment, phosphogypsum can be dehydrated to become semi-hydrated gypsum. On the basis of semi-hydrated gypsum, if an appropriate amount of fine powder such as fly ash, coal ash, coal slime or sand is added, and necessary grinding and mixing are carried out, a high-strength cement raw material can be produced.

[0003] In the process of processing traditional unburned cement, the raw materials required for the processing of unburned cement need to be fully mixed by a mixer. In the specific processing steps, the required raw materials are put into a conveyor in batches, and the raw materials are sent into a mixing tank through the conveyor. The motor drives the stirring paddle to drive the raw materials in the mixing tank to mix and stir;

[0004] However, due to the uneven distribution of the raw materials falling on the conveyor, the raw materials sent from the conveyor to the mixing tank are also unevenly distributed, resulting in the raw materials being easily agglomerated and condensed during the mixing process by the stirring paddle, which increases the difficulty of mixing and reduces the mixing efficiency. More importantly, when the traditional stirring paddle is mixing the raw materials, not only is the stirring method single, which reduces the mixing efficiency, but the raw materials are also easily adhered to the stirring paddle, increasing the weight of the stirring paddle, thereby increasing the driving load of the stirring motor and causing damage to the stirring motor. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a phosphogypsum unburned cement equipment, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides a phosphogypsum unburned cement equipment, comprising a stirring tank and two conveyors installed on the top of the stirring tank and with output ends opposite to the inner cavity of the stirring tank, a stirring component comprising a rotating tube rotatably installed at the center of the inner cavity of the stirring tank, a plurality of stirring frames being installed on the outer tube wall of the rotating tube, strip-shaped installation openings being penetrated through two opposite inner side walls of the stirring frames, stirring blades being obliquely fixedly installed in the strip installation openings, exhaust holes being penetrated through the outer side walls of the stirring blades and provided with exhaust holes, an auxiliary air intake component comprising a fan installed on the outer tank wall of the stirring tank and with the output end being connected to the exhaust holes on the plurality of stirring blades through the rotating tube, and a scraping component comprising a scraping rod which is lifted and slidably installed on the surface of the conveyor belt of the conveyor.

[0008] Furthermore, a feed pipe communicating with the inner cavity of the mixing tank is installed at the bottom end of the mixing tank, a valve is installed in the inner cavity of the feed pipe, and two symmetrically distributed support seats are installed on the outer tank wall of the mixing tank.

[0009] Furthermore, the stirring assembly also includes a fixed seat arranged above the stirring tank, two fixed plates are installed between the outer ring wall of the fixed seat and the inner cavity wall of the stirring tank, and a motor with an output end connected to the rotating tube is installed at the top of the fixed seat.

[0010] Furthermore, the outer tube wall of the rotating tube is provided with a plurality of first air inlet holes and a plurality of second air inlet holes through the inner cavity, and the two ends of the stirring piece are connected with the inner cavity of the rotating tube through the inner cavity of the stirring frame and the corresponding second air inlet holes.

[0011] Furthermore, a cavity communicating with the first air inlet hole is provided in the fixing plate, and the output end of the fan is communicated with the cavity through the fixing plate.

[0012] Furthermore, an upper hopper is installed on the top of the conveyor, and the scraping assembly also includes a mounting plate fixedly installed between two opposite inner walls of the conveyor, and a lifting cylinder is installed on the top of the mounting plate. The output end of the lifting cylinder extends through and extends to the bottom of the mounting plate and is installed with a mounting frame, and the scraping rod is rotatably installed on the mounting frame.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. Replace the traditional stirring paddle with a stirring frame, and embed a fixed stirring blade in the stirring frame. The stirring blade is connected to the fan outside the stirring tank, so that the air blown into the internal airway by the fan is discharged from the stirring blade. This can not only blow off part of the raw materials attached to the stirring blade and the stirring frame, reduce the weight of the stirring frame, thereby reducing the driving load of the stirring motor and protecting the motor from damage, but also can blow the air discharged from the stirring blade into the raw materials to improve the mixing efficiency of the raw materials;

[0015] 2. A scraping rod is set at the conveying end of the conveyor. The raw materials sent from the conveyor to the mixing tank pass through the scraping rod and the conveyor belt, so that they are flattened and scraped by the scraping rod, so that the raw materials falling into the mixing tank are evenly dispersed. In the process of stirring the raw materials with the stirring paddle, the probability of raw material agglomeration and condensation is reduced, thereby improving the stirring efficiency. The scraping rod can be raised and lowered to adjust the height to meet the scraping needs of different raw materials. BRIEF DESCRIPTION OF THE DRAWINGS
