Description

Technical Field

[0001] The invention mainly relates to the technical field of combustion furnaces, and in particular to a feeding device for a combustion furnace which is not prone to backfire. Background Art

[0002] A combustion furnace is a device that converts thermal energy into other forms of energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. Currently, common combustion furnaces use a variety of materials, including wood, coal and other biomass materials.

[0003] When the combustion furnace is working, in order to ensure that the internal heat energy is continuously converted into other energy, it is necessary to continuously transport biomass materials into the interior. In modern industry, in order to improve the combustion efficiency of biomass materials, various materials are made into biomass pellets for combustion. The feeding device is generally composed of a dragon.

[0004] During the operation of the specific embodiment, the inventors found the following defects:

[0005] Although the current Jiaolong conveying device can meet the feeding operation, when the positive pressure combustion occurs in the combustion furnace, the heat energy will be backfired outward through the gaps between the Jiaolongs, which can easily cause the biomass materials being transported to burn and cause a fire. In addition, too many motors are used, and the feeding channel and the Jiaolongs are prone to blockage. The Jiaolong cannot rotate, which can easily cause damage to the motor and high maintenance costs.

[0006] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Summary of the Invention

[0007] The present invention provides a combustion furnace feeding device that is not prone to backfire, which is used to solve the technical problem that although the current dragon conveying device can meet the feeding operation, when positive pressure combustion occurs in the combustion furnace, heat energy will backfire outward through the gaps between the dragons, which can easily cause the biomass material being conveyed to burn and cause a fire.

[0008] The transmission mechanism that this invention provides is as follows: a kind of combustion furnace feeding device that is not easy to backfire, comprises a conveying hopper, a distributing device is provided in the conveying hopper, a side surface of the distributing device is provided with a first gear, the first gear is connected to the first transmission chain, the bottom outlet of the conveying hopper is connected to the feeding channel, one side of the feeding channel is detachably connected to the driving device, the driving device is connected to the first transmission chain, the other side of the feeding channel is provided with an intermittent stopper device, the intermittent stopper device is connected to the first transmission chain, the bottom of the feeding channel is connected to the feeding channel, the rear end of the feeding channel is slidably connected to the push-pull slider, the rear end of the push-pull slider is connected to the reciprocating mechanism, the reciprocating mechanism and the intermittent stopper device are connected through the second transmission chain. This device is different from the traditional dragon feeding method. It adopts reciprocating push-pull feeding, and biomass materials are transported in sections. When this device is working, biomass particles or combustion materials are poured into the conveying hopper at the top, and the driving device is started. The driving device can be a common driving device such as a motor. The driving device drives the first transmission chain to rotate, and then drives the first gear to rotate. The distributing device distributes the biomass particles into the feeding channel at the bottom to prevent the biomass particle material from being blocked. When the biomass material enters the feeding channel, the intermittent blocking device will intermittently feed the biomass particles into the feeding channel at the bottom. In order to prevent backfire, the push-pull process of this device is achieved through the cooperation of various gears. When the biomass particles enter the top of the intermittent blocking device and are blocked, the push-pull slider is at the starting stage of the feeding channel. When the push-pull slider is at the outermost end of the feeding channel, the intermittent blocking device does not block the biomass material, and the biomass material falls to the top of the push-pull slider. When the push-pull slider is at the starting stage again, the biomass material at the top loses support and slides into the feeding channel, and the biomass particles are blocked by the intermittent blocking device again. Therefore, a part of the biomass material will be pushed each time, and the biomass particles will not be continuously transported, preventing the biomass material from being ignited during backfire. The entire device is driven by a driving device, and the various components are connected by gears and transmission chains with high transmission efficiency. The driving device can be connected to the side of the feeding channel by screws, which is easy to maintain and replace.

[0009] Furthermore, a feeding chute is provided inside the conveying hopper, and connecting holes are opened on both sides of the feeding chute, and the connecting holes are rotatably connected to the distributing device.

[0010] Furthermore, the material dividing device includes a rotating column, on which material dividing partitions are arranged at intervals, and a rotating roller is provided in the middle of the rotating column, and one end of the rotating roller is connected to the first gear.

[0011] Furthermore, the driving device includes a support frame, the support frame is detachably connected to the feeding channel, the support frame is detachably connected to a driving motor, the output shaft of the driving motor is connected to a second gear, and the second gear is connected to the first transmission chain.

[0012] Furthermore, the intermittent blocking device includes a symmetrically arranged fixed plate, which is detachably connected to the feeding channel. A plurality of connecting grooves are opened on the fixed plate, which are detachably connected to the rotating shaft. A third gear is provided at one end of the rotating shaft, and the third gear is connected to the first transmission chain. A fourth gear is provided in the middle of the rotating shaft, and a semicircular plate is provided on the side of the fourth gear, and the semicircular plate is connected to the material dividing mechanism.

[0013] Furthermore, the material distribution mechanism includes a rotating shaft, both ends of the rotating shaft are connected to the feeding channel, and two intermittent baffles forming a certain angle are provided on the rotating shaft.

[0014] Furthermore, the reciprocating mechanism has a symmetrically arranged support plate, which is rotatably connected to a transmission roller. A fifth gear is provided in the middle of the transmission roller, and the fifth gear is connected to the fourth gear through the second transmission chain. Both ends of the transmission roller are connected to the first transmission bar, and the end of the first transmission bar is rotatably connected to one end of the second transmission bar, and the other end of the second transmission bar is rotatably connected to the push-pull slider.

[0015] Furthermore, a wear-resistant guide rail is provided on the inner wall of the feeding channel, and corresponding sliders are provided on both sides of the push-pull slider to match it.

[0016] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0017] The present invention has a reasonable design. When feeding the biomass material, the material dividing plate on the material dividing device can play a role of blocking and feeding, thereby preventing the biomass material from being blocked.

[0018] By adjusting the connection between the chain and the gear, the push-pull slider and the intermittent blocking device are adjusted to move asynchronously, which can ensure that the push-pull slider plays a partition role. Moreover, due to the blocking of the intermittent blocking device, the biomass materials pushed each time will not contact each other, which can effectively reduce the safety accidents caused by tempering.

[0019] During the transportation of biomass materials, the slider is pushed and pulled into the furnace for a certain distance each time, and then new biomass particles are pushed in. The particles will not pile up, so they are not easily ignited by backfire. The entire device can be driven by a motor, and the device has low cost and high efficiency.

When the device is working, the biomass particles or combustion materials are poured into the top conveying hopper 1, and the driving device 6 is started. The driving device 6 can be a common driving device such as a motor. The driving device drives the first transmission chain 4 to rotate, and then drives the first gear 3 to rotate, so that The dividing device 2 distributes the biomass particles into the feeding channel 5 at the bottom to prevent the biomass particle material from being blocked. After the biomass material enters the feeding channel 5, the intermittent blocking device 7 will intermittently feed the biomass particles into the feeding channel 8 at the bottom. In order to prevent tempering, the push-pull process of this device is achieved through the cooperation of various gears. When the biomass particles enter the top of the intermittent blocking device 7 and are blocked, the push-pull slider 9 is at the starting stage of the feeding channel 5. When the push-pull slider 9 is at the outermost end of the feeding channel 5, the intermittent blocking device 7 does not enter the biomass material.
