Description

Technical Field

[0001] The utility model belongs to the technical field of the cement silo cover, and particularly relates to a cement silo cover with a rapid drainage structure. Background Art

[0002] The cement silo cover refers to the structure or component covering the top of the cement silo, which is used to close and protect the stored materials inside the cement silo. The cement silo cover can effectively seal the top of the cement silo, prevent external factors (such as rain, sand and dust, etc.) from entering the silo, and protect the stored cement or other materials from being polluted or damaged. The specific design and structural form of the cement silo cover can vary, and corresponding selection and design are carried out according to the type, size and usage requirements of the cement silo. Common cement silo covers include flat tops, domes, conical tops, etc., and the materials include steel structures, fiberglass, etc.

[0003] The existing cement silo covers lack an effective rapid drainage structure, resulting in insufficient drainage capacity when rainwater or other liquids accumulate. This may cause water accumulation on the cover, increasing the load on the cover, possibly affecting the stability of the silo structure, and reducing the dryness inside the silo. The long-term retention of water on the cover may cause corrosion problems. Especially for metal covers, the accumulated water may accelerate the oxidation and corrosion of the metal, leading to a decline in the quality of the cover, leakage or damage. Therefore, we hope to design a cement silo cover with a new structure to solve this problem. Content of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a cement silo cover with a rapid drainage structure to solve the problems put forward in the above background art.

[0005] The utility model is realized through the following technical solutions: A cement silo cover with a rapid drainage structure, comprising: a cement silo body and a cover body. A cover body for closing the top of the cement silo is installed at the upper end of the cement silo body. The cover body includes a guardrail and a cover body, and the guardrail is welded to the upper edge of the cover body.

[0006] A plurality of reinforcing ribs distributed in an equally divided structure are welded on the upper surface of the cover body. A sector-shaped dividing surface is arranged between every two reinforcing ribs, and a baffle is welded to the edge of the upper surface of the cover body.

[0007] A feed inlet is arranged in the middle of the upper end of the cover body. A connecting flange is welded to the upper end of the feed inlet, and a top cover for covering the feed inlet is movably installed above the feed inlet through the connecting flange.

[0008] As a preferred embodiment, the cover body is a frustum-shaped structure with a small top and a large bottom. The lower edge of the cover body is provided with a plurality of fixing holes for connecting with the upper flange of the cement silo body. The lower end of the cover body is clamped on the upper side of the upper flange of the cement silo.

[0009] As a preferred embodiment, the outer ends of the multiple reinforcing ribs are not directly connected to the inner wall of the baffle, and a water guiding gap is set between the end of the multiple reinforcing ribs close to the baffle and the inner wall of the baffle, and the width of the water guiding gap is not less than 5 cm. The setting of the water guiding gap allows the water collected on the lower side of the upper surface of the cover body to be connected to each other and then move to the position of the guide groove.

[0010] As a preferred embodiment, a clearance gap is provided on the right side of the guardrail, and the right side of the baffle is broken to form an arc-shaped gap, and the arc-shaped gap is located directly below the clearance gap.

[0011] As a preferred embodiment, the lower partial spaces of the multiple fan-shaped dividing surfaces form an annular series structure through multiple water-conducting gaps, and the heights of the lower sides of the multiple fan-shaped dividing surfaces are flush, the height of the bottom of the water-conducting gap is flush with the height of the lower sides of the multiple fan-shaped dividing surfaces, and the multiple water-conducting gaps and the lower sides of the multiple fan-shaped dividing surfaces are flush, which can ensure that the accumulated water moves smoothly into the guide groove.

[0012] As a preferred embodiment, a guide groove is provided in the radially outward direction on the right side portion of the cover body located at the arc-shaped notch, and the depth of the guide groove gradually increases from the inside to the radially outside. A guide hole is provided downward at the radially outer bottom of the guide groove, and a guide pipe is installed at the lower side of the guide hole. The lower side of the guide pipe is fixed to the outer wall of the cement silo body and extends to the ground.

[0013] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: by setting the cover body to be a frustum-shaped structure with a small top and a large bottom, when rainwater falls on the upper side of the cover body, its downwardly inclined multiple sector-shaped dividing surfaces cooperate with the reinforcing ribs to effectively and quickly guide the water flow downward, so that the rainwater is quickly collected to the lower side of the multiple sector-shaped dividing surfaces, and quickly moves to the position of the guide groove through the multiple water-guiding gaps. The setting of the water-guiding gaps enables the water collected on the lower side of the upper surface of the cover body to be interconnected, and then can move to the position of the guide groove, thereby preventing rainwater from accumulating on the surface of the cover body;

[0014] The provision of the diversion trough and the diversion holes is such that when the water volume is small, most of the water that enters the diversion trough will enter the diversion holes due to the low flow velocity and finally flow to the ground through the diversion pipes connected to the diversion holes, greatly reducing the erosion of the outer wall of the cement silo body by rainwater. When the water volume is large, due to the large water volume and fast flow velocity of the water entering the diversion trough, only a part of it will enter the diversion holes, and this part will finally flow to the ground through the diversion pipes connected to the diversion holes. While a part of the water flow will directly fall to the ground in a parabolic shape under the action of the diversion of the diversion trough and its own flow velocity inertia, without causing a large amount of rainwater to directly contact the outer wall of the cement silo, greatly reducing the erosion of the outer wall of the cement silo body by rainwater, and avoiding the occurrence of corrosion problems caused by the long-term retention of accumulated water on the cover, which helps to extend the service life of the entire cover structure.

[0024] See also Figures 1 to 5 The utility model provides a technical solution: a cement silo cover with a rapid diversion structure, comprising: a cement silo body 100 and a silo cover body 200, the silo body 100 is provided with a silo cover body 200 for closing the top of the cement silo, the silo cover body 200 comprises a guardrail 210 and a cover body 220, and the guardrail 210 is welded to the upper edge of the cover body 220;

[0025] A plurality of equally distributed reinforcing ribs 223 are welded on the upper surface of the cover body 220, a sector-shaped dividing surface 222 is provided between every two reinforcing ribs 223, and a baffle 221 is welded on the edge of the upper surface of the cover body 220;

[0026] A feed inlet 225 is provided in the middle of the upper end of the cover body 220, a connecting flange is welded to the upper end of the feed inlet 225, and a top cover 224 for covering the feed inlet 225 is movably installed on the upper side of the feed inlet 225 through the connecting flange. Figures 1 to 4 The cover body 220 is a frustum-shaped structure with a small top and a large bottom. The lower edge of the cover body 220 is provided with a plurality of fixing holes for connecting with the upper flange of the cement silo body 100. The lower end of the cover body 220 is clamped on the upper side of the upper flange of the cement silo.

[0027] The outer ends of the multiple reinforcing ribs 223 are not directly connected to the inner wall of the baffle 221, and a water guiding gap 226 is set between the end of the multiple reinforcing ribs 223 close to the baffle 221 and the inner wall of the baffle 221. The width of the water guiding gap 226 is not less than 5 cm. The setting of the water guiding gap 226 allows the water collected on the lower side of the upper surface of the cover body 220 to be connected to each other, and then can move to the position of the guide groove 227.

[0028] A clearance gap is arranged on the right side of the guardrail 210, and the right side of the baffle plate 221 is broken to form an arc-shaped gap, which is located directly below the clearance gap.

[0029] The lower part of the space of the multiple sector-shaped dividing surfaces 222 forms an annular series structure through multiple water-conducting gaps 226, and the heights of the lower sides of the multiple sector-shaped dividing surfaces 222 are flush, the height of the bottom of the water-conducting gap 226 is flush with the height of the lower sides of the multiple sector-shaped dividing surfaces 222, and the multiple water-conducting gaps 226 and the lower sides of the multiple sector-shaped dividing surfaces 222 are flush, which can ensure that the accumulated water moves smoothly into the guide groove 227.

[0030] As the first embodiment of the present utility model, by setting the cover body 220 in a frustum-shaped structure with a smaller upper part and a larger lower part, when rainwater falls on the upper side of the cover body 220, its inclined multiple fan-shaped dividing surfaces 222 cooperate with the reinforcing ribs 223 to effectively and quickly guide the water flow downward, so that the rainwater quickly gathers under the multiple fan-shaped dividing surfaces 222 and quickly moves towards the position of the diversion groove 227 through the multiple water guiding gaps 226. The setting of the water guiding gaps 226 enables the water gathered under the upper surface of the cover body 220 to communicate with each other, and then can move towards the position of the diversion groove 227, avoiding the accumulation of rainwater on the surface of the cover body 220.

[0032] As the second embodiment of the present utility model, based on the above first embodiment, when the water volume is small, most of the water entering the diversion groove 227 will enter the diversion hole 228 due to the low flow rate and finally flow to the ground through the diversion pipe connected to the diversion hole 228, greatly reducing the erosion of the outer wall of the cement silo body 100 by rainwater. When the water volume is large, since the water volume entering the diversion groove 227 is large and the flow rate is fast, only part of it will enter the diversion hole 228. This part finally flows to the ground through the diversion pipe connected to the diversion hole 228, while a part of the water flow will directly fall towards the ground in a parabolic shape under the diversion of the diversion groove 227 and its own flow velocity inertia, and will not cause a large amount of rainwater to directly contact the outer wall of the cement silo, greatly reducing the erosion of the outer wall of the cement silo body 100 by rainwater, avoiding the corrosion problem caused by the long-term retention of accumulated water on the cover, and helping to improve the service life of the entire cover body 220 structure.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
