Description

Technical Field

[0001] The utility model relates to the technical field of feed pipes, in particular to an anti-blocking boiler feed pipe. Background Art

[0002] A biomass power plant is a facility that uses renewable biomass as fuel to generate electricity. Biomass includes organic matter such as plants, crop residues, agricultural waste, wood, and waste paper. These biomass fuels can be converted into heat energy through combustion, fermentation, or chemical reactions, and then converted into electrical energy through generators. The existing biomass fuel transportation is a single pipeline, and there is no anti-blocking structure in the pipeline. It is easy to get blocked during the fuel transportation into the plant. Because the impurities such as soil blocks are relatively moist, they are easy to freeze and condense in the pipeline at the furnace entrance when the temperature is low, which can easily cause blockage of the biomass fuel.

[0003] For example, the utility model patent with authorization announcement number CN 220338491 U (hereinafter referred to as comparative document D1) discloses an anti-clogging boiler feed pipe. As a prior art, when in use, the fuel can smoothly enter the boiler through the vibration of the elastic bottom plate to avoid fuel blockage. However, the structural design is relatively simple and the anti-clogging ability is not strong enough. It can only be unblocked in the straight pipe section. When the material volume is large, when the material enters the inclined pipe section and is blocked at the bottom port thereof, the effect of the elastic bottom plate is not obvious enough. For this reason, we design an anti-clogging boiler feed pipe to solve the above technical problems. Utility Model Content

[0004] The utility model aims to provide an anti-clogging boiler feed pipe to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-clogging boiler feed pipe comprises a boiler feed pipe body, which comprises a straight pipe and an inclined pipe, an elastic bottom plate is provided at the connection between the straight pipe and the inclined pipe, the elastic bottom plate is located in the upper half of the inclined pipe, the lower half of the inclined pipe is provided with a dredging component, the outer surface of the inclined pipe is provided with a power component that provides driving force for the dredging component, the dredging component comprises a movable side plate, a rotating rod, a flip plate, a slider and a slide rod, the upper side wall of the inclined pipe is slidably provided with a movable side plate, the lower side wall of the inclined pipe is provided with a slide groove along the feeding direction, a slide rod is fixedly provided between the left and right side walls in the slide groove, a slide block adapted to the slide groove is slidably provided, the slide block is slidably sleeved on the outside of the slide rod, a rotating rod is rotatably provided at the center position of the outer surface of the movable side plate, the other end of the rotating rod is rotatably connected to the surface of the slider, and a flip plate is symmetrically provided on the surface of the rotating rod.

[0007] The power assembly includes an electric push rod, a motor, a base plate and a shell. An electric push rod is provided at the top of the inclined pipe. The extended end of the electric push rod is connected to the shell. A motor is provided in the shell. A connecting groove is opened at the top of the inclined pipe along the feeding direction. The output shaft of the motor is slidably arranged in the connecting groove. The output shaft of the motor passes through the movable side plate and is connected to one end of the rotating rod.

[0008] As a preferred solution of the utility model: the length of the connecting groove is less than half of the length of the movable side plate.

[0009] As a further preferred solution of the utility model: a bottom plate is provided at the rear end of the electric push rod, and the bottom plate is fixedly connected to the top of the inclined pipe.

[0010] As a further preferred solution of the utility model: the shell is slidably arranged on the top of the inclined pipe.

[0011] As a further preferred solution of the utility model: a plurality of through holes are penetrated through the flap.

[0012] As a further preferred solution of the utility model: the left and right side walls of the slide groove are provided with inclined surfaces expanding toward the inner direction of the inclined pipe.

[0013] As a further preferred solution of the present invention: the length direction of the rotating rod is perpendicular to the material cutting direction.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: when the material enters the bottom of the straight pipe and the upper section of the inclined pipe, the elastic bottom plate can be set to achieve the material unblocking effect there, and when the material enters the lower section of the inclined pipe, if blockage occurs, the motor can be started, and the output shaft of the motor drives the rotating rod to rotate, thereby driving the flip plate to rotate, stirring the material for unblocking, and when the above operation still cannot unblock the blockage well, the electric push rod can be started, and the electric push rod drives the housing together with the motor to move downward at the top of the inclined pipe, and at the same time, it can drive the moving side plate, the rotating rod, and the flip plate It moves in the discharge direction together with the slider, directly moving the rotating flip plate downward to push the blocked material to discharge, thereby improving the material unblocking ability. The device cooperates with the elastic bottom plate to greatly improve the anti-blocking ability; and, since a rotating rod is rotatably provided at the center position of the outer surface of the moving side plate, and the length of the connecting groove is less than half of the length of the moving side plate, the moving side plate can always cover the connecting groove during the movement of the moving side plate, thereby preventing the material inside the inclined pipe from overflowing from the connecting groove. The structural design is ingenious and highly practical, and it is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] See also Figure 1-3 In the embodiment of the utility model, the anti-blocking boiler feed pipe includes a boiler feed pipe body 1, and the boiler feed pipe body 1 includes a straight pipe 16 and an inclined pipe 17. An elastic bottom plate 2 is provided at the connection between the straight pipe 16 and the inclined pipe 17. The design structure of the elastic bottom plate 2 is the same as that recorded in the comparative document D1, which belongs to the prior art and is not elaborated in detail herein. For details, see the comparative document D1. The elastic bottom plate 2 is located in the upper half of the inclined pipe 17, and a dredging component is provided in the lower half of the inclined pipe 17. The outer surface of the inclined pipe 17 is provided with a power component that provides a driving force for the dredging component. The dredging component includes a moving A movable side plate 6, a rotating rod 3, a flip plate 5, a slider 14 and a slide rod 13, a movable side plate 6 is slidably provided on the upper side wall inside the inclined pipe 17, a slide groove 12 is opened on the lower side wall inside the inclined pipe 17 along the feeding direction, a slide rod 13 is fixedly provided between the left and right side walls in the slide groove 12, a slider 14 adapted to the slide groove 12 is slidably provided in the slide groove 12, the slider 14 is slidably sleeved on the outside of the slider 13, a rotating rod 3 is rotatably provided at the center position of the outer surface of the movable side plate 6, the other end of the rotating rod 3 is rotatably connected to the surface of the slider 14, the length direction of the rotating rod 3 is perpendicular to the feeding direction, and a flip plate 5 is symmetrically provided on the surface of the rotating rod 3.

[0021] The power assembly includes an electric push rod 9, a motor 7, a base plate 10 and a shell 8. An electric push rod 9 is provided at the top of the inclined pipe 17. The extended end of the electric push rod 9 is connected to the shell 8. The motor 7 is provided in the shell 8. The shell 8 is slidably arranged on the top of the inclined pipe 17. A connecting groove 11 is opened at the top of the inclined pipe 17 along the feeding direction. The output shaft of the motor 7 is slidably arranged in the connecting groove 11, and the output shaft of the motor 7 passes through the movable side plate 6 and is connected to one end of the rotating rod 3. The length of the connecting groove 11 is less than half of the length of the movable side plate 6. A base plate 10 is provided at the rear end of the electric push rod 9, and the base plate 10 is fixedly connected to the top of the inclined pipe 17.

[0022] A plurality of through holes 4 are formed through the flap plate 5, that is, the flap plate 5 is hollowed out, which can reduce the material cost of the device and the weight of the device without affecting the unblocking and discharge of materials.

[0023] The left and right side walls of the chute 12 are provided with inclined surfaces 15 that expand toward the inside of the inclined pipe 17. When the slider 14 moves along the direction of the slide rod 13, that is, the slider 14 moves in the chute 12, and when the slider 14 moves close to the left and right side walls of the chute 12, the setting of the inclined surfaces 15 can facilitate the slider 14 to squeeze the material inside the chute 12 out of the chute 12, which is conducive to complete material discharge and can avoid the accumulation of materials in the chute 12, causing the movement of the slider 14 to be blocked, thereby affecting the dredging function of the dredging component.

[0024] Specifically, when the material enters the bottom of the straight pipe 16 and the upper section of the inclined pipe 17, the elastic bottom plate 2 can be set to achieve the material unblocking effect there. When the material enters the lower section of the inclined pipe 17, if blockage occurs, the motor 7 can be started, and the output shaft of the motor 7 drives the rotating rod 3 to rotate, thereby driving the flip plate 5 to rotate, stirring the material for unblocking. When the above operation still cannot unblock the blockage well, the electric push rod 9 can be started, and the electric push rod 9 drives the housing 8 together with the motor 7 to move downward at the top of the inclined pipe 17. At the same time, it can drive the moving side plate 6, the rotating rod 3, the flip plate 5 and the slider 14 to move together. It moves in the direction of material discharge, directly causing the rotating flip plate 5 to move downward, pushing the blocked material to be discharged, thereby improving the material unblocking ability. The device cooperates with the elastic bottom plate 2 to greatly improve the anti-blocking ability; and, since a rotating rod 3 is rotatably provided at the center position of the outer surface of the movable side plate 6, and the length of the connecting groove 11 is less than half of the length of the movable side plate 6, the movable side plate 6 can always cover the connecting groove 11 during the movement of the movable side plate 6, thereby preventing the material inside the inclined pipe 17 from overflowing from the connecting groove 11. The structural design is ingenious, and it is highly practical, and it is worthy of promotion.
