Description

Technical Field

[0001] This utility model belongs to the field of pellet fuel feeding technology in material yards, and relates to a feeding control structure for a feeder. Background Technology

[0002] In existing feedstocks, clogging and feed stability issues are common problems during the feeding and guiding of pellet fuel. These shortcomings mainly stem from the physical characteristics of pellet fuel, such as irregular shape, inconsistent size, hygroscopicity, and agglomeration, as well as improper equipment design and operation. Clogging typically occurs in hoppers, conveyor belts, and screw conveyors, due to increased friction between particles or adhesion between particles and equipment walls, leading to obstructed material flow. Poor feed stability manifests as uneven particle distribution and large velocity fluctuations during conveying, which affects subsequent processing or combustion efficiency.

[0003] Conventional solutions include using vibrating equipment, improving material properties (such as reducing humidity through drying), and adjusting conveyor speed and angle. Vibrating equipment can reduce particle adhesion and improve flowability; improving material properties avoids agglomeration by controlling humidity and temperature; and adjusting conveyor speed and angle aims to optimize material flow. However, these methods also have drawbacks. While using vibrating equipment can reduce clogging, long-term vibration may lead to accelerated equipment wear, increased maintenance costs, and potential noise pollution. Material property improvement measures require additional drying equipment and energy consumption, increasing operating costs. Therefore, there is an urgent need for a feeder control structure to address these issues. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a feeding control structure for a feeder, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a feeding control structure for a feeder, including: a dropping hopper and a feeding rod, wherein the front cross-section of the dropping hopper is an inverted trapezoidal structure, the dropping hopper is provided with a set of dropping troughs for receiving pellet fuel in the material yard, and the lower end of the dropping hopper is provided with a set of receiving seats for connecting and fixing with the lower support frame.

[0006] The lower end of the receiving seat has a rectangular cross-section when viewed from below. The lower end of the receiving seat is provided with a set of lower support frames for connecting and supporting the upper receiving seat. The inner side of the lower support frame is provided with a set of guide shells for conducting the pellet fuel in the material yard. The inner side of the guide shells is provided with a set of inner guide chambers for guiding the pellet fuel in the material yard. Inside the inner guide chambers is a set of guide augers for actively guiding the pellet fuel in a spiral motion. The middle position inside the guide augers is provided with a set of rotating shafts for driving the guide augers to rotate.

[0007] In a preferred embodiment, the rotating shaft is fixedly connected to the middle position of the guide auger, and a set of limiting bearings for maintaining stable rotation is provided on the right side of the rotating shaft. The limiting bearings are fixedly connected to the middle position of the left side of the side cover.

[0008] In a preferred embodiment, a set of bearing seats is provided on the outer side of the right end of the rotating shaft to maintain the stability of the left side of the rotating shaft and to close the left side of the guide shell. A set of sealed bearings is provided in the middle of the bearing seats. In actual use, the operator introduces the pellet fuel from the material yard through the feed chute. By starting the motor, the motor drives the coupling and the rotating shaft to rotate. The rotating shaft drives the guide auger inside the guide shell to move and guide the pellet fuel from left to right. At the same time, during the rotation of the rotating shaft, the sealing bearings and the limit bearings restrict the rotation of the rotating shaft and the guide auger, thereby maintaining the stability of the feeding effect of the feeder and reducing the occurrence of pellet fuel jamming in the material yard.

[0009] In a preferred embodiment, the rotating shaft passes through the center of the sealed bearing, and a set of couplings for connecting the motor power transmission is provided on the left side of the rotating shaft, and a set of motors for providing power to the couplings is provided on the left side of the couplings.

[0010] In a preferred embodiment, the right side of the material guide shell is provided with a set of side seals to keep its right side closed, and the left and right sides of the lower end of the material guide shell are respectively provided with a set of support legs to support its lower end.

[0011] As a preferred embodiment, the upper left end of the right-side support leg is provided with a set of feeding hoppers that are interconnected with the inside of the material guide shell, and the inside of the feeding hoppers is interconnected with the inside of the material guide shell.

[0012] In a preferred embodiment, the lower end of the feed guide shell is provided with a set of conveyor belts for guiding the pellet fuel from the feed yard. The feed hopper is equipped with 44 feed rods for adjusting the position of the pellet fuel as it falls into the feed hopper. When the pellet fuel is guided to the upper end of the feed hopper by the feed guide auger, the feed rods can effectively adjust the position of the fuel falling into the belt, reducing leakage. At the same time, the number and depth of the feed rods can be adjusted according to different fuels. Combined with the frequency of the screw feeder, it can adapt to uniform feeding when different types of fuel are used, without clogging.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by starting the motor, the motor drives the coupling and the rotating shaft to rotate. The rotating shaft drives the guiding auger inside the guiding shell to move and guide the pellet fuel in the material yard from left to right. At the same time, during the rotation of the rotating shaft, the rotating shaft and the guiding auger are kept stable by the restriction of the sealed bearing and the limit bearing, which further improves the stability of the feeder and reduces the occurrence of pellet fuel jamming in the material yard.

[0014] After the pellet fuel in the material yard is guided to the upper end of the feed hopper by the guide auger, its feed rod can effectively adjust the position of the fuel falling into the belt, reduce material leakage, and adjust the number and depth of insertion according to different fuels. Combined with the frequency of the screw feeder, it can adapt to uniform feeding when burning different types of fuels without clogging. Attached Figure Description
