BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION
[0014] In order to enable those skilled in the art to more clearly understand the purpose, technical solutions and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.
[0015] In the description of the present invention, it should be understood that the orientations or positional relationships indicated by terms such as "upper", "lower", "left", "right", "inside", "outside", "horizontal", and "vertical" are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or original referred to must have a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.
[0016] The present invention will be described in detail below with reference to the accompanying drawings: Figure 1 As shown, a dust-free unloading device for a boiler slag bin includes a dust-free unloading device body, which consists of a discharge hopper 1, a lifting mechanism and a dust collector, wherein the discharge hopper 1 is a trapezoidal structure with a small top and a large bottom, and the bottom edge of the discharge hopper 1 is wrapped with a circle of dust-proof cloth 2, and the bottom of the discharge hopper 1 faces the carriage of the slag bin loading vehicle, and a feed port 3 is provided in the middle position of the top surface of the discharge hopper 1, and at least two dust collecting ports 4 are provided on both sides of the feed port 3 at the top of the discharge hopper, the feed port 3 is connected to the discharge pipe 5, the discharge pipe 5 is connected to the ash bin, and a discharge valve 6 is provided on the discharge pipe 5 for controlling the opening or closing of the pipe, and a dust collecting pipe 7 with a lifting mechanism is provided at the dust collecting port 4, and the dust collecting pipe 7 collects dust through the dust collector arranged just above it, and the lifting mechanism is used to drive the entire discharge hopper 1 to rise and fall, and when the material of the slag bin loading vehicle is loaded, the entire discharge hopper 1 is lifted.
[0017] The lifting mechanism consists of multiple dust collecting sleeves 8, a transverse connecting rod 9 and at least two lifting rods 10. The number of the dust collecting sleeves 8 corresponds to the number of the dust collecting pipes 7, and the diameter of the dust collecting sleeves 8 is smaller than the diameter of the dust collecting pipes 7. Each dust collecting sleeve 8 is inserted into the dust collecting pipe 7 and partially exposed in the dust collecting pipe 7. The dust collecting pipe 7 is inserted into the dust collecting port 4. A first limiting ring 11 with a diameter larger than the dust collecting port 4 is installed at the bottom of the dust collecting pipe 7. A second limiting ring 12 with a diameter larger than the dust collecting port 4 is also provided on the dust collecting pipe 7 directly above the dust collecting port 4. The height difference between the first limiting ring 11 and the second limiting ring 12 is used as the lifting adjustment range. The two adjacent dust collecting sleeves 8 are connected by a transverse connecting rod 9, and the transverse connecting rod 9 is respectively provided with two through holes 13 for the lifting rod 10 to pass through. One end of the lifting rod 10 is connected to the top surface of the discharge hopper 1, and the other end is installed on the lifting platform 14. The lifting rod 10 is driven to lift and lower by the lifting equipment. The lifting equipment can be conventional equipment, such as hydraulic lifting devices, etc., which can meet actual needs.
[0018] It is worth noting that the dust collecting duct and the dust collection port in the present invention are not fixedly connected. After the dust collecting duct is inserted into the dust collection port, a first limiting ring and a second limiting ring are respectively provided on the upper and lower sides of the dust collection port on the dust collecting duct, so that the dust collecting duct can cooperate with the telescopic rod to move up and down within a range at the dust collection port, and the distance between the first limiting ring and the second limiting ring can be adjusted to meet actual needs. Due to the setting of the first limiting ring and the second limiting ring, the dust collecting sleeve and the dust collecting duct are also not fixedly connected, and the dust collecting sleeve can move up and down in the dust collecting duct. The length of the dust collecting sleeve inserted into the dust collecting duct must be greater than the distance between the first limiting ring and the second limiting ring, so as to ensure that the dust collecting sleeve will not fall out of the dust collecting duct during the lifting process.
[0019] The dust collector consists of a dust removal pipe 15, a dust removal fan 16 with a motor and a dust collection device 20. One end of the dust removal pipe 15 is connected to the dust removal fan 16, and the other end thereof is provided with multiple dust removal branch pipes 17. Each dust removal branch pipe 17 is respectively arranged directly above each dust collecting sleeve 8. The dust collection device 20 is connected to the dust removal fan 16. The dust removal fan 16 collects dust from the dust collecting sleeve 8 through the dust removal branch pipe 17, thereby realizing the dust removal operation of the discharge hopper 1, and the dust is collected and centrally processed through the dust collection device 20.
[0020] At least one infrared probe 18 is provided on the left and right sides of the inner wall of the discharge hopper 1. The infrared probe 18 is used to monitor the material height of the carriage of the slag storage loader at the bottom of the discharge hopper. The infrared probe 18 and the discharge valve 6 are both controlled by the control system. When the material height of the carriage reaches the preset height, the infrared probe 18 feeds back the data to the control system, and the control system controls the discharge valve 6 to close.
[0021] The ends of the dust removal branch pipes 17 are respectively provided with a dust removal cover 19, which is in an eight-shaped structure and is used to improve the dust removal effect. The control system is a PLC controller.
[0022] The electric gate door sealing and ash cleaning device designed by the utility model takes pressure from the coal-spreading air main pipe, and introduces it into the rear of the electric gate door through a stainless steel pipe, a manual air valve switch, and a stainless steel metal hose. Under normal boiler operation, the coal-spreading air is in a smooth state. During operation, the manual air valve is manually opened to maintain a long-term ash-cleaning state. The manual valve is closed when the fire is suppressed or the boiler is shut down, thereby effectively preventing the electric gate door from being in an open state during operation, which would cause a large amount of coal ash to accumulate at the rear over time and affect the transmission system inside, thereby improving the overall service life.
[0023] The dust-free unloading device for boiler slag bin designed by the utility model can eliminate the dust floating outside when loading and unloading the slag bin through the designed dust collector, thereby reducing environmental pollution, ensuring the health of workers, and reducing the labor intensity of subsequent manual sanitation cleaning. The lifting mechanism designed can adjust the height to meet the actual height requirements of slag bin slag discharge and transportation, and can also reduce the dust caused by unloading due to height difference to a certain extent.
[0024] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, any equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical concepts disclosed in this utility model shall be covered by the claims of this utility model.
