Description
Technical Field
[0001] This utility model belongs to the technical field of boiler equipment, and specifically relates to an ash and slag cleaning device for boilers. Background Technology
[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy. The original meaning of "boiler" refers to a water-filled container heated over a fire, while "furnace" refers to the place where fuel is burned. A boiler consists of two main parts: the boiler and the furnace. The hot water or steam produced in a boiler can directly provide the heat energy needed for industrial production and people's lives. It can also be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used for domestic purposes, with some applications in industrial production. Boilers that produce steam are called steam boilers, often simply referred to as boilers, and are mostly used in thermal power plants, ships, locomotives, and industrial and mining enterprises.
[0003] In response, Chinese patent application number CN 216667715 U discloses an ash and slag cleaning device for boilers, including a boiler body, a support leg fixedly connected to the bottom of the boiler body, an ash and slag box fixedly connected to the bottom of the boiler body, an ash and slag container fixedly connected to the inner wall of the ash and slag box, a connecting box fixedly connected to the bottom of the ash and slag box, and a water tank fixedly connected to the inner wall of the connecting box. This ash and slag cleaning device for boilers, through the ash and slag box, ash and slag container, connecting box, water tank, water pump, water suction pipe, water outlet pipe, conduit, nozzle, motor, rotating shaft, rotating plate, and cleaning brush, can simultaneously wet the ash and slag to prevent ash and slag from flying during cleaning, and simultaneously clean the ash and slag collection box, thereby improving the cleaning effect, preventing ash and slag from adhering to the ash and slag box and causing cleaning inconvenience, and also preventing flying ash and slag from affecting the health of workers.
[0004] However, in actual use, due to its structural limitations, this structure can only perform simple cleaning and maintenance of ash and slag on the boiler inner wall. It cannot be adapted to complete the all-round and uniform cleaning of the boiler inner wall, resulting in poor cleaning effect. At the same time, the equipment cannot properly collect and process the ash and slag, which cannot meet the daily use needs. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be solved. Utility Model Content
[0005] The purpose of this utility model is to provide an ash and slag cleaning device for boilers, in order to solve the problem that existing structures, due to their own structural limitations, can only perform simple cleaning and maintenance operations on the ash and slag inside the boiler, and cannot be adapted to complete the all-round and uniform cleaning operation of the boiler inner wall, resulting in poor cleaning effect. At the same time, the equipment cannot properly collect and process the cleaned ash and slag, and cannot meet the daily use needs.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an ash and slag cleaning device for a boiler, comprising a boiler body, wherein a liquid transfer pipe is provided at the center of the interior of the boiler body, a connecting side seat is provided on the side of the liquid transfer pipe, and a side cleaning scraper is fixedly connected to one end of the connecting side seat.
[0007] A cover is fixedly connected to the bottom end of the boiler body, a filter frame is fixedly connected to the bottom end of the cover, a support base is fixedly connected to the bottom end of the filter frame, and a liquid storage valve seat is provided on the side of the filter frame.
[0008] Preferably, a pull-out cover is movably connected to the side of the cover seat, and sealing strips are provided at both ends of the pull-out cover.
[0009] Preferably, the inside of the cover and the pull cover is provided with a storage ring groove, and the inside center of the cover is provided with a drive motor.
[0010] Preferably, a shrink cover is provided on the side of the connecting side seat, and a scraping side pad is provided on the side of the side cleaning scraper.
[0011] Preferably, an electric push rod is provided at both the upper and lower ends of the interior of the connecting side seat, and an infusion grid is provided at the center of the interior of the connecting side seat.
[0012] Preferably, the top end of the infusion tube is fixedly connected to an inlet shaft connector, the bottom end of the infusion tube is fixedly connected to a scraping base, and a connecting base is provided at the center of the bottom end of the scraping base.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This boiler ash and slag cleaning device, through its boiler body, liquid delivery pipe, connecting side seat, side cleaning scraper, shrink hood, scraping side pad, electric push rod, liquid delivery grid, liquid inlet shaft connector, scraping base, and connecting base, enables a more suitable ash and slag cleaning operation for the boiler's inner wall. In actual use, the operator first removes the stirring structure inside the boiler body, then installs the liquid delivery pipe in the center of the boiler body where the original stirring equipment was located. Then, starting the drive motor will rotate and adjust the liquid delivery pipe. This allows the scraping base and connecting base at the bottom of the infusion transfer tube, as well as the connecting side seat and side cleaning scraper on the side, to rotate efficiently, performing ash and slag cleaning operations on the inner wall. At the same time, the electric push rod in the center of the connecting side seat can be activated to drive the connecting side seat to extend and retract, so that the scraping side pad on the side of the side cleaning scraper fits and abuts against the inner wall of the boiler. The inlet shaft at the top of the infusion transfer tube delivers the cleaning fluid, and the infusion grid in the center of the connecting side seat guides the flow, completing the flushing and treatment of ash and slag on the inner wall of the boiler, demonstrating the practicality of the equipment design.
[0015] 2. This boiler ash and slag cleaning device, through its boiler body, cover seat, filter frame, support base, liquid storage valve seat, extraction cover, sealing strip, storage ring groove, and drive motor, further improves the overall performance of the equipment. During daily use, the ring structure composed of the cover seat and extraction cover can be installed on the outer surface of the drive motor. The slag generated during daily cleaning of the boiler body can enter the storage ring groove between the cover seat and the extraction cover. Then, the wastewater is filtered and discharged through the liquid storage valve seat of the filter frame at the bottom of the cover seat. The ash and slag temporarily stored in the storage ring groove can be quickly cleaned by removing the extraction cover, demonstrating the comprehensiveness of the equipment design.
