Description

Technical Field

[0001] The utility model relates to the technical field of cement storage, in particular to a cement silo for preventing caking. Background Technique

[0002] A cement silo is a large closed tank mainly used for storing bulk cement, generally used in projects such as construction and water conservancy. In existing cement plants, a large amount of bulk cement is usually stored. These bulk cements are stored relatively concentrated in the cement silo. During the long-term use process, due to the continuous accumulation of cement, the cement will form lumps or adhere to the inner wall of the cement silo, resulting in the blockage of the discharge port and poor material discharge. This requires daily maintenance and regular cleaning of the cement silo during the production process.

[0003] Currently, the mainstream method for cleaning the caked cement on the silo wall is generally to scrape the cement by setting a scraper inside the silo body. For example, a storage bin for cement production disclosed in the Chinese authorized patent CN220975278 U scrapes the caked cement on the inner wall of the silo body by setting a rotatable scraper structure (turning rod) to achieve the cleaning purpose. However, obviously, the existence of this scraper structure interferes with the operation of the entire cement silo. First, the airflow generated by the rotation of the scraper will intensify the dust rising and pollute the environment. Second, when the cement silo is full of cement, the scraper is surrounded by cement, with great resistance, hindering the operation of the scraper structure, thereby increasing the load of the scraper and seriously damaging the scraper in severe cases.

[0004] Therefore, our company has developed this cement silo structure, which can solve the above problems without generating dust and increasing the load of the scraper structure on the premise of ensuring the removal of caked cement. Content of the Utility Model

[0019] (III) Beneficial effects

[0020] The utility model provides a cement library for preventing caking. It has the following beneficial effects:

[0021] The anti-caking cement silo is provided with a follow-up lifting scraper structure. The position of the scraper drops as the cement in the silo sinks. During the descending process, the scraper first scrapes the caked cement on the silo wall, and then cooperates with the high-pressure blowing mechanism to blow the cement blocks, so as to clean the caked cement completely. Compared with the traditional rotary scraper structure, the dusting phenomenon is greatly reduced. Since the scraper is located at the top of the cement layer, there is no resistance, so the load of the scraper will not be increased. Further, the sealing plate on the scraper can effectively prevent dust from polluting the environment. Furthermore, by setting the vibration component, the silo wall can be continuously knocked, so as to shake off the caked cement by vibration and effectively relieve the caking problem.

Detailed Description of the Preferred Embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Such as Figure 1-2As shown in the figure, the present utility model provides a technical solution: an anti-caking cement silo, which includes a silo body 1. A feed inlet 2 is provided at the top of the silo body 1. It should be noted that when the cement is filled, the feed inlet 2 needs to be sealed to avoid contact with the outside. A slidable sealing plate 3 is provided in the inner cavity of the silo body 1. A through groove of the same size as the feed inlet 2 is provided in the middle of the sealing plate 3 (to facilitate the entry of cement from the feed inlet 2 into the silo body 1).

[0029] As Figure 3 shown, a drying cavity 17 is provided in the sealing plate 3. A detachable honeycomb plate 18 is provided at the top of the drying cavity 17. By filling desiccant in the drying cavity 17, moisture is prevented from contacting the cement. The honeycomb plate 18 is provided to facilitate the desiccant to absorb moisture.

[0030] As Figure 1 shown, a rotatable winding rack 4 is provided at the bottom of the silo body 1. A turning handle 41 is provided on the winding rack 4. By rotating the turning handle 41, the sealing plate 3 can be reset. A rotatable guide wheel 5 is provided at the top of the silo body 1. A traction rope 6 is wound around the winding rack 4. The end of the traction rope 6 bypasses the guide wheel 5 and is fixed to the sealing plate 3 inside the silo body 1.

[0031] As Figure 2-3 shown, an annular scraping knife 10 is embedded on the outer side of the sealing plate 3.

[0032] As Figure 1-2 shown, a chute 19 is provided on the outer side of the scraping knife 10. A slide rail 20 is provided on the inner wall of the silo body 1. The chute 19 is slidably installed on the slide rail 20. The purpose of this design is to ensure that the sealing plate 3 always slides down in a vertical posture without shaking.

[0033] As Figure 3 shown, an annular high-pressure blowing pipe 8 is provided in the sealing plate 3. The blowing direction of the high-pressure blowing pipe 8 is directly opposite to the inner wall of the silo body 1. A high-pressure air pump 7 is provided at the top of the silo body 1. The high-pressure air pump 7 is connected to the high-pressure blowing pipe 8 through a hose 9 (the length of the hose 9 is long enough to ensure that the sealing plate 3 can sink to the bottom of the silo body 1).

[0034] As Figure 3 shown, an inclined ash discharging step 26 is provided at the bottom of the sealing plate 3. The blown cement blocks automatically fall from the ash discharging step 26.

[0035] As Figure 4As shown in the figure, a vibration component is also provided on the outer side of the library body 1. The vibration component includes a motor 11 located outside the library body 1. A first gear 12 is installed at the output end of the motor 11. A second gear 13 is engaged at the top of the first gear 12. Both the first gear 12 and the second gear 13 are gears with a broken tooth structure (as for the setting of the number of broken teeth, it can be adjusted in advance according to the rotation angle of the striking block 16). Above the second gear 13, a rotatable rotating rod 14 is provided. A striking block 16 is provided at the bottom of the rotating rod 14. The top of the rotating rod 14 is connected to the library body 1 through a spring 15. The rotating rod 14 is connected to the second gear 13 through a thin rope.

[0036] As Figure 1 shown, a discharge port 21 is provided at the bottom of the library body 1.

[0037] A conveying pipeline 22 is installed at the bottom of the discharge port 21. A rotatable spiral feeding shaft 23 is provided inside the conveying pipeline 22. The spiral feeding shaft 23 is driven by an external servo motor 24. A discharge pipe 25 is provided at the bottom of the conveying pipeline 22. Since the self-weight of the cement layer is relatively large, generally speaking, when the cement is discharged from the discharge port 21, the impact effect is relatively large, especially when the cement is just filled. Therefore, a dust problem will occur at the position of the discharge port 21. For this reason, we have set up the conveying pipeline 22. The cement is directly discharged into the conveying pipeline 22. The servo motor 24 is turned on to drive the spiral feeding shaft 23 to rotate, so as to smoothly discharge the cement from the discharge pipe 25 and reduce dust.

[0038] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0039] During use, the cement enters the inside of the library body 1 through the feeding port 2 at the top. When the library body 1 is filled with cement, the sealing plate 3 is located at the top of the cement layer, sealing the cement inside the library body 1. When the cement is gradually discharged from the discharge port 21, the overall height of the cement layer will decrease accordingly. Due to its own weight, the sealing plate 3 will automatically sink following the height of the cement layer (that is, the sealing plate 3 is always located at the top position of the cement layer). During this process, the sinking of the sealing plate 3 will drive the traction rope 6 to sink together.

[0040] Turn on the high-pressure air pump 7, blow out high-pressure air flow through the high-pressure blowing pipe 8, quickly disperse and loosen the caked cement, and make it fall off from the library wall, which is convenient for the subsequent removal by the scraper 10. Since the top of the high-pressure blowing pipe 8 is completely blocked by the scraper 10, no dust phenomenon will occur.

[0041] Utilize the pressure of the self-weight of the sealing plate 3. Through the frictional force between the scraper 10 and the inner wall of the silo body 1, scrape the caked cement on the silo wall. Until the cement is completely discharged, the sealing plate 3 then reaches the bottom of the silo body 1. Then, by rotating the turning handle 41, drive the sealing plate 3 to reset. After the cement is refilled again, the sealing plate 3 automatically falls on the top of the cement layer, and so on in a cycle.

[0042] Furthermore, turn on the servo motor 11 to drive the first gear 12 to rotate, thereby driving the second gear 13 to rotate. Since both the first gear 12 and the second gear 13 are of incomplete tooth structures, the second gear 13 will only rotate a certain angle and then stop rotating each time. During this process, the second gear 13 drives the rotating rod 14 to also rotate a certain angle and then stop rotating. And this rotation angle just drives the striking block 16 that was originally in a vertical state to deflect and strike the silo wall, thereby generating vibration and shaking off the caked cement. During the intermittent stop of the rotating rod 14, drive the rotating rod 14 to quickly reset through the spring 15 until the first gear 12 drives the second gear 13 to rotate again next time, and then the striking block 16 strikes the silo wall again, and so on in a cycle.

[0043] In summary, for this anti-caking cement silo, by setting up a follow-up lifting type scraper structure, the position of the scraper automatically descends following the sinking of the cement in the cement silo. During the descent process, first scrape the caked cement on the silo wall through the scraper, and then cooperate with the high-pressure blowing mechanism to blow the cement blocks, thereby cleaning the caked cement. Compared with the traditional rotating type scraper structure, it greatly reduces the dusting phenomenon. Since the scraper is located on the top of the cement layer, there is no resistance either, so it will not increase the load of the scraper. Furthermore, the sealing plate on the scraper can effectively prevent dust from polluting the environment; even further, by setting up a vibration knocking component, it can continuously knock on the silo wall, thereby using vibration to shake off the caked cement and effectively alleviating the caking problem.
