Description

Technical Field

[0001] The utility model relates to the field of garbage incineration equipment, in particular to a bucket elevator used for transmitting fly ash from garbage incineration. Background Art

[0002] The waste incineration power plant collects domestic waste and incinerates it in a unified manner. It uses the heat from incineration to generate electricity while treating the waste gas generated by incineration in a unified manner, making rational use of resources while avoiding waste gas pollution. After the incineration of waste, a certain amount of fly ash will be generated. This part of the fly ash is captured by the flue gas purification equipment and transferred to the fly ash storage tank by the bucket elevator for subsequent resource utilization or stabilized landfill.

[0003] A bucket elevator generally includes a fuselage, a lifting chamber is vertically arranged inside the fuselage, a feed channel is arranged near the bottom of the fuselage, one end of the feed channel serves as a feed port, and the other end is connected to the lifting chamber, a discharge channel is arranged near the top of the fuselage, one end of the discharge channel serves as a discharge port, and the other end is connected to the lifting chamber, a driving sprocket located at the top and a driven sprocket located at the bottom are rotatably arranged in the lifting chamber, the driving sprocket and the driven sprocket sleeve are provided with a transmission chain, a hopper is fixedly arranged on the transmission chain for lifting fly ash from the bottom of the lifting chamber to the top and then pouring it into the discharge channel, a driving platform is arranged around the top on the outside of the fuselage, and the driving platform is provided with a lifting motor for driving the driving sprocket to rotate.

[0004] The bucket elevator with the above structure has certain disadvantages. Fly ash adheres to and accumulates on the inner wall of the feed channel due to moisture in the gas or the characteristics of the material contained therein. Over time, the flow area of ​​the feed channel is reduced, and the conveying capacity of the elevator is also reduced. On the one hand, it takes a certain amount of time to discover the reduction in conveying capacity. On the other hand, the outer shell needs to be disassembled to clean the inner wall, which brings a lot of inconvenience to maintenance. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a bucket elevator for transporting fly ash from garbage incineration, which ensures smooth transmission.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: it comprises a fuselage, a lifting chamber is vertically arranged in the fuselage, a feeding channel is arranged near the bottom of the fuselage, one end of the feeding channel serves as a feeding port, and the other end is connected to the lifting chamber, a discharging channel is arranged near the top of the fuselage, one end of the discharging channel serves as a discharging port, and the other end is connected to the lifting chamber, a driving sprocket located at the top and a driven sprocket located at the bottom are rotatably arranged in the lifting chamber, the driving sprocket and the driven sprocket are sleeved with a transmission chain, and the transmission chain is fixedly provided with a The bottom of the lifting chamber is lifted to the top and then poured into the hopper of the discharge channel. A driving platform is arranged around the top on the outside of the fuselage. The driving platform is provided with a lifting motor that drives the active sprocket to rotate. It is characterized in that: the feed channel includes a vertically arranged first section, an arc-shaped transition second section and a horizontally arranged third section from the feed port to the lifting chamber, a scraper shaft is rotatably arranged in the second section, and scraper plates are equidistantly arranged on the outer circumference of the scraper shaft for scraping the inner wall and moving the fly ash to the lifting chamber when rotating, and a scraper motor that drives the scraper shaft to rotate is arranged on the outside of the fuselage.

[0007] By adopting the above technical scheme, the captured fly ash is poured into the feed port, and the fly ash falls between adjacent scraper plates and is transmitted as the scraper shaft rotates. After it rotates to be opposite to the lifting chamber, the inertia of the fly ash sends it into the lifting chamber. The above structure has the following advantages: ① Multiple scraper plates cooperate, and when the scraper shaft rotates, the second section of the inner wall where fly ash is easily accumulated is continuously scraped to avoid the possibility of fly ash accumulation on the inner wall and ensure smooth transmission; ② In addition to scraping the inner wall, the scraper plates also assist the fly ash entering the feed channel, so that it can quickly turn and pass through the feed channel, thereby improving the transmission efficiency while reducing the residence time and further reducing the possibility of blockage.

[0008] The utility model is further configured as follows: a sinking trough is arranged at the bottom of the lifting chamber, the moving path of the hopper passes through the sinking trough, and the hopper receives the fly ash moved by the scraper plate when passing the lowest position and approaching the third section.

[0009] By adopting the above technical scheme, in the traditional structure, the fly ash needs to be first transferred to the bottom of the lifting chamber, and after the fly ash accumulates to a certain height, it is scooped up by the hopper and transferred upward. In this scheme, the bottom of the lifting chamber is designed to be sunken, so that the hopper passes through the feed port from bottom to top. During the process, most of the fly ash moved by the scraper plate can directly enter the hopper, which greatly improves the transmission efficiency.

[0010] The utility model is further configured as follows: a portion of the scraper plate that contacts the inner wall of the feed channel is detachably provided with a rubber scraper strip.

[0011] By adopting the above technical solution, the rubber scraper strip replaces the rigid contact, so that the scraper and flicker plate can contact the feed channel more closely, ensuring the scraping and flicking effects. At the same time, the detachable installation method makes it easy to replace the rubber scraper strip in time after wear, thereby extending the operating life of the equipment.

[0012] The utility model is further configured as follows: the cross section of the discharge channel is a right triangle, the vertical right-angled side of the discharge channel cross section serves as the connection position with the lifting chamber and extends to the top of the lifting chamber, the horizontal right-angled side of the discharge channel cross section is connected to the bottom of the vertical right-angled side and serves as the discharge port and is shorter than the vertical right-angled side, and the cross section of the discharge channel is located on the hypotenuse and is provided with a turning wall opposite to the lifting chamber.

[0013] By adopting the above technical solution, when the hopper is turned over and pours the fly ash into the discharge channel, the connecting position receives the fly ash, and the fly ash collides with the turning wall and moves downward and leaves the discharge channel from the discharge port. The large inlet design extending to the top ensures complete transmission, and the impact turning combined with the small outlet design ensures transmission efficiency while facilitating subsequent equipment to receive the fly ash.

[0014] The utility model is further configured as follows: the bottom surface of the hopper is in an arc shape, and when the hopper passes through the discharge channel, the bottom surface forms a guiding slope surface for guiding the fly ash of the next hopper to enter the discharge channel.

[0015] By adopting the above technical solution, the bottom of the hopper is reasonably utilized to form a guiding slope to guide the fly ash into the discharge channel, so that the fly ash can be discharged more completely from the discharge port, reducing the possibility of fly ash falling back into the lifting chamber, thereby improving the transmission efficiency.
