Technical Field
[0001] The utility model relates to the technical field of cement outbound delivery, in particular to a cement bottom warehouse outbound delivery structure with agglomeration and crushing functions. Background Art
[0002] At present, many cement production plants have adopted a combined grinding system consisting of a ball mill, a roller press, and a high-efficiency powder classifier in their cement grinding production lines, and then store the finished cement powder in a steel plate warehouse or a vertical warehouse.
[0003] During the storage of existing cement powder in the warehouse, due to water leakage in the warehouse, climate and environmental influences, temperature difference before and inside the warehouse, etc., the cement powder in the warehouse will have different degrees of cement compaction and cement agglomeration. If these agglomerated cements are mixed with other cement powders during the outbound flow, it is easy to block the cement outbound flow valve, making it impossible to unload the cement in the warehouse, and at the same time greatly reducing the quality of the finished cement mixed with gypsum dehydrated agglomerated cement. During the outbound process, bulk delivery and vehicle unloading are relatively smooth in winter, but in summer, due to the high temperature of cement and high air humidity, it is very easy to form a sticky wall in the cement tank truck, resulting in unloading or difficulty. Some cement plants will cool the cement by blowing with fans during the unloading process, but the effect is poor, and it causes a lot of dust to fly, polluting the working environment. Based on the above problems, we provide a cement bottom warehouse outbound structure with agglomeration crushing function. Utility Model Content

[0007] The above technical solution is adopted: the vibration motor drives the screening box to vibrate, and cooperates with the screen to screen out the agglomerated cement. Since the heat dissipation effect of the vibration motor is poor, in order to make the vibration motor operate normally in a high temperature environment, the fan is used to dissipate the heat, and the vents discharge the heat in the protective box.

By arranging the water inlet pipe 18, the water outlet pipe 19 and the water pump 20, cooling water can be poured into the cooling box 9 through the water inlet pipe 18 and the water pump 20. When the cooling water heats up too quickly or the temperature is high, the cooling water inside the cooling box 9 is replaced through the water pump 20 and the water pump, which is convenient for cooling the cement powder.
[0025] Brief description of the use process: During the process of the structure being shipped out of the warehouse, the cement powder enters the screening box 1 through the feed port 21, and then the cement powder falls into the screen 2. The coarseness of the screen 2 needs to be adjusted according to the actual use. Then the vibration motor 42 is turned on, and the vibration motor 42 drives the screening box 1 to vibrate, and the screening box 1 drives the screen 2 to vibrate. The cement powder vibrates on the screen 2. The unagglomerated cement powder can pass through the screen 2, and is guided by the drainage plate 3, and enters the cooling box 9 through the material hose 23. The cement agglomerates due to The volume is too large to pass through the screen 2, and because the screen 2 is set obliquely, the cement lumps are affected by the vibration and its own gravity, roll to the slag discharge port 5, and then discharged through the slag discharge bin 6. The telescopic rod 7 at the bottom of the screening box 1 is fixed to the top of the cooling box 9. When the screening box 1 vibrates, the spring 8 prevents the cooling box 9 from vibrating with it, so as to effectively screen out impurities and agglomerated cement in the cement powder, avoid the agglomerated cement blocking the discharge port and affecting the cement discharge and the quality of the cement product, and greatly improve the outbound speed of the cement powder.
[0026] Embodiment 2:
[0027] See also Figure 1 and Figure 2 A cement bottom storage outbound structure with a caking and crushing function comprises a telescopic rod 7, a cooling box 9 is bolted to the bottom of the telescopic rod 7, cooling pipes 10 are bolted to both sides of the inner cavity of the cooling box 9, a discharge pipe 11 is bolted to the bottom of the cooling pipe 10, a spiral feed shaft 12 is rotatably connected to the right side of the inner cavity of the cooling pipe 10 through a bearing, a servo motor 13 is bolted to the left side of the bottom of the cooling box 9, a driving wheel 14 is bolted to the output end of the servo motor 13, a driven wheel 15 is bolted to the left side of the spiral feed shaft 12 through the cooling box 9, a first chain 16 is meshed with the surface of the driving wheel 14, and a second chain 17 is meshed between the driving wheels 14 and 14.
[0028] See also Figure 1 and Figure 2 A feed inlet 21 is provided at the top of the screening box 1, and a discharge pipe 22 is bolted to the right side of the bottom of the cooling box 9. By providing the feed inlet 21 and the discharge pipe 22, the feeding and discharging of the structure can be facilitated.
[0029] See also Figure 1 and Figure 2 A material passing hose 23 is bolted to the bottom of the screening box 1. By providing the material passing hose, the material passing hose can be prevented from breaking during the vibration process.
[0030] Brief description of the use process: After the cement powder enters the cooling pipe 10 through the material hose 23, the servo motor 13 is turned on. When the motor rotates, it drives the driving wheel 14 to rotate. When the driving wheel 14 rotates, it drives the first chain 16 to rotate. The first chain 16 drives the driven wheel 15 to rotate. The driven wheel 15 drives the second chain 17 to rotate, thereby driving all the spiral feed shafts 12 to rotate. Since the spiral feed shafts 12 rotate to one side at the same time, the spiral directions on the surface of the spiral feed shaft 12 are different, and the upper and lower spiral directions are both opposite. Then, the water pump 20 is turned on to pour cooling water into the cooling box 9 through the water inlet pipe 18. After the cooling water contacts the cooling pipe 10, the low temperature is transferred to the inner wall of the cooling pipe 10. The high-temperature cement powder is cooled by contacting the low-temperature cooling pipe 10. If the powder temperature If the temperature of the cement powder is too high and the cooling time is too long, the rotation speed of the servo motor 13 can be reduced. At this time, the rotation speed of the spiral feed shaft 12 is also reduced, and the cement powder can be cooled for a longer time in the cooling box 9. Similarly, when the cooling water is affected by the heat transfer of the high-temperature cement, if the temperature of the cooling water rises quickly, the water pump 20 can be turned on to discharge the water through the outlet pipe 19 and then refill the cooling water to achieve the purpose of efficient cooling, so as to effectively cool the cement in the cooling box 9. By controlling the rotation speed of the servo motor 13, it is convenient to control the feeding speed of the cement powder, avoid the problem of cement forming a wall in the cement tank truck due to excessive temperature during feeding, avoid the problem of cement dust flying due to the heat dissipation of the cement by the fan, and greatly improve the efficiency of cement feeding.
