Description

Technical Field

[0001] The utility model belongs to the technical field of biogas burners, in particular to a biogas filtering device for a boiler burner. Background Art

[0002] Boiler burner refers to the burner used on the boiler. Boiler burner is the most important equipment among the auxiliary equipment of oil and gas boilers. Boiler burners are mainly divided into oil burners, gas burners and dual-fuel burners (also called oil and gas dual-purpose burners). Oil burners can be divided into light oil burners and heavy oil burners. Light oil mainly refers to diesel, and heavy oil refers to the heavy oil left after gasoline and diesel are extracted from crude oil; gas burners can be divided into natural gas burners, city gas burners, liquefied petroleum gas burners and biogas burners.

[0003] The biogas used in the biogas burner is mainly produced by anaerobic fermentation of organic matter in the garbage. The water vapor content in the biogas is relatively high, which will affect the quality and combustion efficiency of the biogas. Therefore, the biogas needs to be filtered and dehydrated, and the filtering device needs to be drained regularly. When draining, part of the biogas is easily discharged synchronously with the liquid, resulting in waste of biogas. For this reason, it is necessary to design a biogas filtering device that can automatically drain the filtering device and avoid waste caused by leakage of biogas. Utility Model Content

[0004] The purpose of the utility model is to provide a boiler burner biogas filtering device to solve the technical problems mentioned in the above background technology.

[0005] The utility model provides a technical solution to the above-mentioned technical problems as follows: a biogas filtering device for a boiler burner, comprising a biogas filtering tank body: an air inlet and an air outlet are respectively arranged on both sides of the top of the biogas filtering tank body, a drain pipe is arranged on the bottom plate of the biogas filtering tank body, the drain pipe is communicated with the inner cavity of the biogas filtering tank body, a movable pipe is fixedly connected to the center of the bottom of the inner cavity of the biogas filtering tank body, the movable pipe is arranged just above the inner cavity of the drain pipe, the inner cavity of the movable pipe is slidably connected to a connecting rod extending to the outside, a piston is fixedly installed at the bottom of the connecting rod, the piston slides in the inner cavity of the movable pipe, a drainage groove is opened at the bottom of the surface of the movable pipe, a connecting rope is fixedly connected to the top of the connecting rod, and a floating plate is fixedly connected to the top of the connecting rope.

[0006] Preferably, support legs are welded to the bottom of the biogas filtering tank.

[0007] Preferably, a plurality of balls are provided on the upper portion of the inner surface of the movable tube, and the balls roll on the surface of the connecting rod.

[0008] Preferably, a movable cavity is opened at the top of the connecting rod, the inner cavity of the movable cavity is rotatably connected to a winding post, and the bottom of the connecting rope is fixedly connected to the surface of the winding post.

[0009] Preferably, the winding post is rotatably connected to the inner cavity of the active cavity via a torsion spring.

[0010] 1. The beneficial effect of the utility model is that the utility model realizes the purpose of automatic drainage by driving the piston to slide up and down through the floating plate. When the floating plate slides down to drive the piston to seal the inner cavity of the drainage groove, there is still some water at the bottom of the inner cavity of the biogas filter tank, thereby preventing biogas from leaking out, thereby achieving the purpose of automatically draining the biogas filter tank and avoiding biogas leakage and waste.

[0011] 2. The utility model arranges a torsion spring on the winding column. When the water level drops, the resilience of the torsion spring drives the winding column to reset and rotate, thereby driving the winding column to wind the connecting rope, thereby pulling the floating plate downward, so that the floating plate can be lowered to the top of the connecting rod. As the water level drops, the connecting rod is pressed downward by the gravity of the floating plate itself. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1-4 The utility model shows a boiler burner biogas filtering device of an embodiment of the utility model, which includes a biogas filtering tank body 1: an air inlet 2 and an air outlet 3 are respectively arranged on both sides of the top of the biogas filtering tank body 1, a supporting leg 4 is welded to the bottom of the biogas filtering tank body 1, a drain pipe 5 is arranged on the bottom plate of the biogas filtering tank body 1, the drain pipe 5 is communicated with the inner cavity of the biogas filtering tank body 1, a movable pipe 6 is fixedly connected to the center of the bottom of the inner cavity of the biogas filtering tank body 1, the movable pipe 6 is arranged just above the inner cavity of the drain pipe 5, the inner cavity of the movable pipe 6 is slidably connected to a connecting rod 7 extending to the outside, a piston 8 is fixedly installed at the bottom of the connecting rod 7, the piston 8 slides in the inner cavity of the movable pipe 6, a drainage groove 9 is opened at the bottom of the surface of the movable pipe 6, a connecting rope 10 is fixedly connected to the top of the connecting rod 7, and a connecting rope 10 is connected to the top of the connecting rod 7. A floating plate 11 is fixedly connected to the top of the rope 10, and a plurality of balls 12 are arranged on the upper part of the inner surface of the movable tube 6. The balls 12 roll on the surface of the connecting rod 7. An active cavity 13 is opened at the top of the connecting rod 7. A winding post 14 is rotatably connected to the inner cavity of the active cavity 13. The bottom of the connecting rope 10 is fixedly connected to the surface of the winding post 14. The winding post 14 is rotatably connected to the inner cavity of the active cavity 13 through a torsion spring. By setting the torsion spring on the winding post 14, when the water level drops, the rebound force of the torsion spring is used to drive the winding post 14 to reset and rotate, thereby driving the winding post 14 to wind the connecting rope 10, thereby pulling the floating plate 11 downward, so that the floating plate 11 can drop to the top of the connecting rod 7, so that as the water level drops, the gravity of the floating plate 11 itself is used to press the connecting rod 7 downward.

[0023] Working principle: When the utility model is used, the user first connects the biogas to allow the biogas to enter the biogas filter tank body 1 through the air inlet 2, and the liquid is separated from the inner wall of the biogas filter tank body 1 by the centrifugal force through the separator inside the biogas filter tank body 1, and finally gathers at the bottom of the inner cavity of the biogas filter tank body 1, and the biogas flows upward through the reversing pipe and is discharged through the air outlet 3. As the water level in the biogas filter tank body 1 rises, the floating plate 11 is driven to slide upward. When the water level rises to the highest point, the piston 8 is pulled in the movable tube 6. The cavity slides upward to open the inner cavity of the drainage trough 9 and starts to drain water. As the water level drops, the floating plate 11 is driven to slide down. At this time, the winding post 14 is driven to rotate in the inner cavity of the movable cavity 13 due to the resilience of the torsion spring in the winding post 14, thereby driving the bottom of the connecting rope 10 to be wound around the surface of the winding post 14. When the floating plate 11 drops to the top of the connecting rod 7, the floating plate 11 will press the connecting rod 7 downward, thereby driving the piston 8 to slide down and seal the drainage trough 9, thereby ending the drainage. At this time, there is still some water at the bottom of the inner cavity of the biogas filter tank body 1, thereby preventing biogas leakage.

[0024] To sum up: the boiler burner biogas filtering device drives the piston 8 to slide up and down through the floating plate 11 to achieve the purpose of automatic drainage. When the floating plate 11 slides down to drive the piston 8 to seal the inner cavity of the drainage groove 9, there is still some water at the bottom of the inner cavity of the biogas filtering tank body 1, thereby avoiding biogas leakage, and the purpose of automatically draining the biogas filtering tank body 1 and avoiding biogas leakage and waste can be achieved.

[0025] The technical features disclosed above are not limited to the disclosed combinations with other features. Those skilled in the art may also make other combinations between the technical features according to the purpose of the utility model to achieve the purpose of the utility model.
