[0017] The following is combined with Figure 1 The specific implementation modes of the present utility model are further described in detail.

[0018] Depend on Figure 1The utility model provides a limestone powder conveying system, comprising a feed bin 1, a drying bin 3 and a storage bin 4. A stirring mechanism 5 is provided in both the feed bin 1 and the drying bin 3, and a screening component 6 is also provided in the feed bin 1. The feed bin 1 is used to break up the limestone powder, and the broken limestone powder enters the drying bin 3 for drying, and the dried limestone powder is then sent to the storage bin 4 for storage. The above is the prior art, and specific reference may be made to the Chinese utility model patent application No. 202321466470.8 for a limestone powder conveying system, which will not be described in detail here. With respect to the prior art, a screening component 6 is also provided in the feed bin 1, and when the limestone powder is wet, it is difficult to separate it only by the stirring mechanism 5 in the feed bin 1. Therefore, the purpose of this application is to improve the prior art, and the main improvements are as follows:

[0019] The lower end of the feed bin 1 is connected with a buffer bin 2, and the buffer bin 2 is connected to the upper end of the drying bin 3 through a feed pipe 7. The feed pipe 7 is provided with a first negative pressure pump 8. A heating device 9 is installed in the drying bin 3, and the heating device 9 can be an electric heating plate or an electric heating wire. The upper end of the drying bin 3 is connected to the upper end of the feed bin 1 through a hot air pipe 10, and the discharge end of the drying bin 3 is connected to the feed end of the storage bin 4. Through the arrangement of the above structure, when in use, the buffer bin 2 is used to temporarily store small-particle limestone powder materials screened by the screening component 6. The small-particle materials in the buffer bin 2 can be sent to the drying bin 3 through the first negative pressure pump 8. The action of the first negative pressure pump 8 increases the air pressure in the drying bin 3, so that the heat in the drying bin 3 overflows into the feed bin 1 through the hot air pipe 10. In this way, the moist material in the feed bin 1 can be heated, so that the agglomerated limestone powder can be better broken up.

[0020] In some embodiments, a cyclone dust collector 11 is installed at the upper feed end of the storage bin 4, and the inlet of the cyclone dust collector 11 is connected to the discharge end of the drying bin 3 through a discharge pipe 12. The discharge pipe 12 is installed with a second negative pressure pump 13. After the limestone powder is dried, the material in the drying bin 3 is drawn into the cyclone dust collector 11 by the second negative pressure pump 13. After the dust is removed by the cyclone dust collector 11, the dust is discharged through the cyclone dust collector 11, and the dusted material enters the storage bin 4 and is collected.

[0021] In some embodiments, the outlet of the cyclone dust collector 11 is connected to a bag dust collector 14 for collecting dust.

[0022] Preferably, a star valve 15 is connected between the feed bin 1 and the buffer bin 2. The setting of the star valve 15 plays a good partitioning role between the buffer bin 2 and the feed bin 1. It can be understood that the limestone powder screened by the screening component 6 is relatively dry, so the humidity in the buffer bin 2 is lower than the humidity in the feed bin 1. Through the setting of the star valve 15, when the limestone powder in the buffer bin 2 reaches a certain amount, the first negative pressure pump 7 works, which can reduce the humid air in the feed bin 1 from being drawn into the drying bin 3.

[0023] In some embodiments, a feed hopper 16 is installed at the upper end of the feed bin 1 .

[0024] In some embodiments, an exhaust pipe 17 is installed at the upper end of the feed bin 1 , and a pressure relief valve 18 is installed in the exhaust pipe 17 for relieving pressure inside the feed bin 1 .

[0025] In some embodiments, the feed pipe 7 is installed with a humidity sensor 19 for detecting the humidity of the limestone powder fed into the drying bin 3 .

[0026] The utility model discloses a limestone powder conveying system that uses a hot air pipe 10 to convey the hot air from the drying bin 3 to the feed bin 1, thereby changing the humidity and temperature inside the feed bin 1, which helps to improve the breaking up effect of the limestone powder and improve the operating efficiency of the system. It effectively solves the problem that the limestone powder is difficult to effectively break up due to excessive humidity in the traditional system, and improves the stability and reliability of the entire conveying process.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
