Description

Technical Field

[0001] This utility model relates to the technical field of chain return cyclone conveying funnel structural components, specifically a quick-replaceable wear-resistant funnel bottom plate. Background Technology

[0002] Chainlink's high-capacity pellet production line places high demands on the continuity and stability of its thermal processing system. Frequent shutdowns make it difficult to control thermal process parameters, leading to a decline in the quality of finished pellets. The biggest problem hindering stable and smooth production in the pelletizing system is the wear of the conveyor funnels. The bottom surface of funnels made of ordinary steel plates wears out in about two months, resulting in leaks. This leakage increases the amount of cleaning required at workstations and may even lead to shutdowns for emergency repairs, putting production in a passive situation. Furthermore, spilled pellets on the ground pose a safety risk of personnel slipping and falling.

[0003] Using wear-resistant alloys to make funnels can extend their service life, but using wear-resistant alloy steel to make funnels is costly, alloy steel is difficult to cut, and materials for different funnels need to be customized, resulting in a long procurement cycle, which is not conducive to actual needs on site. Secondly, after multiple patching and welding, the base plate of ordinary funnels can no longer be patched and welded, and the entire funnel base plate needs to be replaced. The replacement of the funnel base plate involves a large amount of cutting and welding, and the replacement time is long.

[0004] By designing and modifying the bottom surface of the funnel, baffles are evenly distributed and welded on the bottom surface of the funnel. During the conveying process, the material is stored between adjacent baffles. When the material passes through the funnel, it will not cause direct erosion or wear to the bottom plate of the funnel, thereby improving the service life of the funnel. Utility Model Content

[0005] The purpose of this utility model is to provide a wear-resistant funnel base plate that is reasonably designed, easy to process, has low processing and manufacturing costs, is convenient to install and operate, can extend the service life of the funnel, is economical and environmentally friendly, greatly improves the service life of the funnel, saves time and effort in installation, reduces the labor intensity of workers, and improves the wear resistance of the funnel.

[0006] This utility model discloses a quick-replaceable wear-resistant funnel bottom plate, comprising a plate body, with a short side plate and a long side plate fixedly connected to opposite side walls of the plate body, a first connecting plate fixedly connected to one side wall of the short side plate, and a second connecting plate fixedly connected to one side wall of the long side plate, with a plurality of first mounting holes evenly arranged on the surfaces of the first and second connecting plates.

[0007] The base plate of the funnel is formed by the plate body and the short and long side plates fixedly connected to both sides. This base plate is sturdy, durable, and wear-resistant, improving its service life and extending the lifespan of the funnel. Simultaneously, a first connecting plate and a second connecting plate are fixedly connected to one edge of each of the short and long side plates. Multiple first mounting holes are evenly distributed on the surfaces of the first and second connecting plates, allowing for quick and easy replacement of the original base plate after damage. Simply align the first and second connecting plates and the first mounting holes with the connecting edge of the funnel, and then use fixing bolts to secure the base plate to the connecting edge of the funnel. Installation and disassembly are convenient, and the base plate can be custom-made according to the dimensions of the funnel's connecting edge, making operation more flexible and adaptable. It eliminates the need to replace the entire funnel, is economical and environmentally friendly, saves production costs, and brings economic benefits to enterprises.

[0008] Multiple partitions are uniformly fixedly installed on the surface of the plate, and the edges of the partitions are fixedly connected to the inner wall of the long side plate.

[0009] The partition is inclined, and the included angle between the partition and the plate body is 40°-45°.

[0010] Multiple baffles are located between the inner walls of the plate and the long side plate. They can be used to store materials. During normal production, the multiple baffles form a material flow channel. The stored materials can isolate the plate from the wear and erosion caused by the conveying medium, thereby achieving the purpose of wear prevention for the entire bottom plate. They also reduce the direct erosion of the plate by the material due to gravity and can buffer the material being conveyed at high speed. This protects the plate, short side plate, and long side plate from long-term erosion by the material, fully protecting the entire bottom plate, extending the service life of the bottom plate, and thus extending the service life of the entire funnel.

[0011] Setting the partition at an angle can better buffer materials moving at high speeds without affecting the flow of materials, thus further extending the service life of the base plate.

[0012] The first connecting plate is fixedly connected to the third connecting plate, and the second connecting plate is fixedly connected to the fourth connecting plate. The surfaces of the third and fourth connecting plates are provided with second mounting holes, which coincide with the first mounting holes. The third connecting plate coincides with the first connecting plate, and the fourth connecting plate coincides with the second connecting plate. A fixing bolt is installed through the second mounting hole and the first mounting hole to fix the third connecting plate and the first connecting plate, and the fourth connecting plate is fixedly connected to the second connecting plate. The bottom surfaces of the third and fourth connecting plates are fixedly connected to a funnel-shaped mating surface.

[0013] When the worn base plate needs to be replaced, the new base plate can be fixedly connected to the third connecting plate and the first connecting plate by a fixing bolt installed through the second mounting hole and the first mounting hole. The fourth connecting plate is fixedly connected to the second connecting plate. The bottom surfaces of the third and fourth connecting plates are fixedly connected to the funnel mating surface, so it can be quickly and easily fixedly installed on the funnel mating surface. Only partial replacement is needed, without replacing the entire funnel. It is economical, environmentally friendly, and cost-effective. After replacing the base plate, the service life is increased from the original two months to twelve months, which is more than six times longer. The installation time can be completed by two people in two hours, saving time and effort and reducing the labor intensity of the workers.

[0014] The beneficial effects of this utility model are: 1) The base plate of the funnel is formed by the plate body and the short and long side plates fixedly connected to both sides. This base plate is sturdy, durable, and wear-resistant, improving its service life and extending the life of the funnel. At the same time, a first connecting plate and a second connecting plate are fixedly connected to one edge of the short and long side plates, respectively. Multiple first mounting holes are evenly arranged on the surface of the first and second connecting plates. This allows for quick and easy replacement of the original base plate after it is damaged. Simply align the first and second connecting plates and the first mounting holes with the connecting edge of the funnel, and then use fixing bolts to fix the base plate to the connecting edge of the funnel. Installation and disassembly are convenient. It can be processed and manufactured according to the size of the connecting edge of the funnel, making the operation more flexible and the applicability strong. There is no need to replace the entire funnel, which is economical and environmentally friendly, saves production costs, and brings economic benefits to enterprises.

[0015] 2) Multiple baffles are located between the inner walls of the plate and the long side plate. They can be used to store materials.

This protects the plate, short side plate and long side plate from long-term scouring by the material, fully protects the entire bottom plate, extends the service life of the bottom plate, and thus extends the service life of the entire funnel.

[0016] 3) Setting the partition at an angle can better buffer materials moving at high speeds without affecting the flow of materials, thus further improving the service life of the base plate.

[0017] 4) When the worn base plate needs to be replaced, the new base plate can be fixedly connected to the third connecting plate and the first connecting plate by installing fixing bolts through the second mounting hole and the first mounting hole. The fourth connecting plate is fixedly connected to the second connecting plate.
