[0011] The utility model is further described below in combination with the drawings and examples.

[0012] Figure 1 Is the main view structure schematic diagram of the utility model embodiment,

[0013] Figure 2 Is the cut structure schematic diagram of the utility model embodiment,

[0014] Figure 3 Is Figure 2 The local node big sample of the middle.

[0015] Mark explanation: side wall 1, feed inlet 2, feed groove 3, fan 4, baffle 5, guard plate 6, support rod 7, lifting ring 8, enclosure plate 9, button spring 10. Specific implementation

[0016] The technical scheme in the utility model is further described below in combination with the drawings and examples.

[0017] Please refer to Figures 1-3 , a kind of phosphogypsum water stable material stirrer feed structure, the phosphogypsum is transported using conveying belt, the end of conveying belt is arranged at feed, including feed groove 3, fan 4 and baffle 5, the side wall 1 of the stirrer is provided with feed inlet 2, the feed groove 3 is enclosed at feed inlet 2, the baffle 5 is fixed on the side wall 1 of stirrer and is located on feed groove 3, baffle 5 and feed groove 3 are enclosed into the feed channel leading to feed product, conveying belt transports phosphogypsum to feed channel, the fan 4 is installed on the side wall 1 of stirrer and is communicated inside and outside stirrer, and the fan 4 is located between feed inlet 2 and baffle 5.

[0018] Working principle is that the phosphogypsum water stable material stirrer feed structure is set closed feed channel by feed groove 3 and baffle 5 at feed inlet 2 on the side wall 1 of stirrer, and cooperates with the fan 4 installed between feed inlet 2 and baffle 5, utilizes the airflow guiding effect generated by fan 4, ensures that phosphogypsum smoothly enters inside stirrer along the set path, avoids material accumulation and dust leakage, and realizes efficient, environmental protection feed process.

[0019] In the embodiment, as shown in Figure 2 , the fan 4 is provided with the guard plate 6 outside, and the guard plate 6 is located between the fan 4 and the feed groove 3. The guard plate 6 is used to reduce the amount of phosphogypsum dust attached to the fan 4, and to reduce maintenance costs.

[0020] In another embodiment, as Figure 2As shown, the protective plate 6 is hinged to the baffle 5, and a support rod 7 is hinged to the protective plate 6. A hook is provided at the end of the support rod 7. Several lifting rings 8 are spaced apart on the bottom surface of the baffle 5, and the hook is hung on one of the lifting rings 8. By hanging the support rod 7 on different lifting rings 8, the position of the protective plate 6 within the feeding channel is changed, thereby changing the diameter of the feeding channel and adjusting the negative pressure airflow of the feeding channel to regulate the dust capture force.

[0021] In this embodiment, as Figure 2 As shown, the baffle 5 is inclined upwards to facilitate the feeding of phosphogypsum.

[0022] In another embodiment, such as Figure 2 , Figure 3 As shown, a protective plate 9 is hinged to the top of the feed trough 3. A spring 10 is sleeved on the hinge shaft of the protective plate 9, and the spring 10 causes the protective plate 9 to move towards the baffle 5. The action of the spring 10 causes the protective plate 9 to rest against the lower end of the conveyor belt, reducing the space for phosphogypsum to scatter and reducing dust dispersion.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
