Description

Technical Field

[0001] The present application relates to the technical field of boiler equipment, and specifically discloses a numerically controlled mechanical environmentally friendly boiler. Background Art

[0002] Environmentally friendly boiler is a relatively general concept. As the name suggests, environmentally friendly boiler refers to a boiler whose exhaust gas emissions can meet environmental protection requirements. It does not refer to a specific type of boiler. The flue gas emissions of coal-fired boilers can also meet environmental protection requirements after desulfurization and dust removal treatment, that is, it refers to a boiler whose flue gas emissions meet national standards.

[0003] The structure of the boiler in the prior art mostly includes a furnace body with a water jacket, a furnace, a grate and a smoke chamber. A grate is arranged between the furnace and the furnace chamber. A water pipe is arranged in the water jacket, and a water pipe is arranged in the smoke chamber. The heat of the flue gas generated by the combustion of coal is transferred to the water pipe. However, the flue gas of the boiler with this structure rises quickly, the contact time with the water pipe is short, and the contact area is small, thus causing waste of heat energy.

[0004] Therefore, in view of this, the inventor provides a numerically controlled mechanical environmentally friendly boiler to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to solve the problem of insufficient thermal energy utilization of the existing numerically controlled mechanical environmentally friendly boilers.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a CNC mechanical environmental protection boiler, including a furnace body, an air duct connected to the furnace body and a heat exchange furnace connected to the air duct. A driving member is provided on the outside of the furnace body, and a cleaning structure driven by the driving member for cleaning the inner wall of the furnace body and a flow control structure for controlling the flow of flue gas are provided inside the furnace body. Filter plates and flow collectors for gathering flue gas are sequentially provided in the direction of flue gas flow in the furnace body. The flow collector is connected to the air duct. The flow control structure includes a transmission seat driven by the driving member to rotate and with a protruding block fixed at the end, a sliding structure driven by the protruding block to slide back and forth up and down, and a sphere fixed at the bottom of the sliding structure and capable of intermittently blocking the air duct. The heat exchange furnace is provided with a heat exchange structure and an exhaust pipe for exhausting flue gas.

[0007] The principles and effects of this basic solution are:

[0008] 1. Compared with the prior art, the utility model sets a driving member in cooperation with the flow control structure. When the driving member rotates, it drives the transmission seat and the protrusion to rotate quickly. The protrusion block presses down the sliding structure for a period of time during the rotation process, so that the ball moves down to block the air guide pipe, thereby achieving the effect of controlling the flow of flue gas entering the heat exchange furnace, preventing excessive flue gas from flowing into the heat exchange furnace within a certain period of time, causing a certain amount of heat energy waste, and solving the problem of insufficient utilization of heat energy in existing boilers.

[0009] 2. The utility model utilizes the rotation effect of the driving member to drive the transmission seat to rotate while causing the cleaning structure to rotate synchronously, so that the cleaning nozzle cleans the inner wall of the furnace body to prevent scaling of the inner wall of the furnace body. The scaling of the inner wall of the furnace body will affect the thermal conductivity and heat energy transfer. Therefore, the cooperation of the cleaning structure can enhance the effect of heat energy utilization.

[0010] Furthermore, the driving member is a servo motor, and the servo motor is electrically connected to a controller, and the servo motor is controlled by the controller.

[0011] Furthermore, the cleaning structure includes a cleaning plate coaxially connected to the output shaft of the servo motor, a plurality of cleaning nozzles arranged on the cleaning plate, and a cleaning pipe connected to the cleaning plate for introducing a cleaning agent.

[0012] Furthermore, the sliding structure includes a dovetail groove arranged on the side wall of the furnace body, a guide rod vertically slidably connected in the dovetail groove, a reset spring for resetting the guide rod, and a driven seat connected to the end of the guide rod, and the ball is fixedly connected to the bottom of the driven seat.

[0013] Furthermore, it also includes a pipe wall scraping structure driven by the ball, the pipe wall scraping structure includes a pressing rod connected to the bottom of the ball, a sliding groove provided in the flow collecting bucket for the filter plate to slide down, and a scraping block slidably connected in the sliding groove and used to install the filter plate. By utilizing the descent of the ball, the pressing rod is driven downward so that the scraping block scrapes the pipe wall of the flow collecting bucket, and the filter screen is lowered at the same time.

[0014] Furthermore, the furnace body is also provided with a filter plate cleaning structure driven by flue gas during the descent of the filter screen, the filter plate cleaning structure comprises a first rotating shaft rotatably connected to the furnace body, an impeller coaxially connected to the first rotating shaft and driven to rotate by airflow, a mounting seat for mounting the first rotating shaft, a second rotating shaft fixed to the mounting seat, and a scraper fixed to the end of the second rotating shaft and abutting against the end surface of the filter plate, the second rotating shaft being rotatably connected to the combustion pot. The airflow on the flue gas drives the impeller to rotate, thereby driving the scraper to rotate, so that the scraper scrapes the smoke particles adhering to the filter plate, so that the filtering effect is better.

[0015] Furthermore, the heat exchange structure is a heat exchange tube arranged in the heat exchange furnace. The shape of the heat exchange tube is spiral, and both ends of the heat exchange tube are respectively connected with a water inlet and a water outlet.

[0016] Furthermore, the heat exchange structure is a heat exchange tube arranged in the heat exchange furnace. The shape of the heat exchange tube is spiral. One end of the heat exchange tube is connected to the smoke exhaust pipe, and the other end is connected to the smoke outlet pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In this embodiment, the heat exchange structure is a heat exchange tube 16 installed in the heat exchange furnace. The heat exchange tube 16 is spiral in shape.
