[0029] Reference Figures 1-4 A star feeder suitable for gasifiers is provided, which includes an adaptive component 200.

[0030] Specifically, the main component 100 includes a housing 101, a feed chute 102, a discharge chute 103, an impeller 104, a protective member 105, and a motor 106. The feed chute 102 is located at the top of the housing 101, the discharge chute 103 is located at the bottom of the housing 101, the impeller 104 is located on one side of the inner cavity of the housing 101, the protective member 105 is located at the top of the inner cavity of the housing 101, and the motor 106 is fixedly connected to one side of the housing 101 and cooperates with the impeller 104; and,

[0031] The adaptive component 200, located on the other side of the inner cavity of the housing 101, includes a jaw plate 201, a connecting rod 202, a bearing seat 203, a tensioning element 204, a limiting element 205, and a wear element 206. The jaw plate 201 is located on one side of the impeller 104, the connecting rod 202 is fixedly connected to the top of the jaw plate 201, the bearing seat 203 is rotatably connected to one side of the connecting rod 202, and the bearing seat 203 is fixedly connected to one side of the inner cavity of the housing 101. The tensioning element 204 is located on the other side of the connecting rod 202, the limiting element 205 is located on one side of the bearing seat 203, and the wear element 206 is located on one side of the limiting element 205.

[0032] The feed chute 102 is used for material entry; the discharge chute 103 is used for material discharge; the impeller 104 is located on one side of the inner cavity of the housing 101 and is driven by the motor 106 to realize material conveying; the protective component 105 is located at the top of the inner cavity of the housing 101 and is used to protect the internal components.

[0033] Jaw plate 201 is located on one side of impeller 104. When large particles enter, it moves under the pressure of the material, increasing the gap with impeller 104 and allowing large particles to pass through smoothly. Connecting rod 202 is fixedly connected to the top of jaw plate 201 to transmit the movement of jaw plate 201. Bearing seat 203 is rotatably connected to one side of connecting rod 202 and fixed in the inner cavity of housing 101, providing support for the rotation of connecting rod 202. Tensioning member 204 is located on the other side of connecting rod 202, using elastic force to allow jaw plate 201 to return to its initial position after the material passes through. Limiting member 205 is located on one side of bearing seat 203 to limit the movement range and initial position of jaw plate 201. Wear member 206 is located on one side of limiting member 205, which can reduce the wear of jaw plate 201 and facilitate replacement when the wear is severe, ensuring stable operation of the equipment.

[0034] Specifically, the protective component 105 includes a first protective plate 105a fixedly connected to one side of the top of the inner cavity of the housing 101, and the first protective plate 105a cooperates with the bearing seat 203.

[0035] The first protective plate 105a is fixedly connected to one side of the top of the inner cavity of the outer shell 101 and cooperates with the bearing seat 203 to protect the bearing seat 203, prevent materials from damaging the bearing seat 203, and extend its service life.

[0036] Specifically, the protective component 105 also includes a second protective plate 105b fixedly connected to the other side of the top of the inner cavity of the housing 101, and the second protective plate 105b cooperates with the impeller 104.

[0037] The second protective plate 105b is fixedly connected to the other side of the top of the inner cavity of the housing 101, and cooperates with the impeller 104 to protect the impeller 104 from direct impact and wear of materials, ensuring the normal operation of the impeller 104.

[0038] Specifically, the tensioning member 204 includes a sleeve 204a disposed on one side of the housing 101. A movable rod 204b is disposed in the inner cavity of the sleeve 204a. A reset plate 204c is fixedly connected to the bottom of the movable rod 204b by bolts. A spring 204d is sleeved on the surface of the movable rod 204b. The bottom of the spring 204d contacts the reset plate 204c, and the top of the spring 204d contacts the top of the inner cavity of the sleeve 204a. The top of the movable rod 204b penetrates the sleeve 204a and is hinged to the connecting rod 202 by a pin.

[0039] The sleeve 204a, movable rod 204b, reset plate 204c, and spring 204d in the tensioning component 204 work together. When large particles of material squeeze the jaw plate 201, the jaw plate 201 drives the connecting rod 202 to move the movable rod 204b upward, causing the spring 204d to deform, thereby increasing the gap between the jaw plate 201 and the impeller 104, allowing the large particles of material to pass through. After the material passes through, the elastic force of the spring 204d causes the movable rod 204b to reset, and the jaw plate 201 returns to its initial position.

[0040] Specifically, the tensioning member 204 also includes a hinge seat 204e hinged to the bottom of the sleeve 204a, and a mounting plate 204f is fixedly connected to the bottom of the hinge seat 204e. One side of the mounting plate 204f is fixedly connected to the outer casing 101.

[0041] The hinge 204e and mounting plate 204f enable the sleeve 204a to be stably installed on the housing 101, ensuring the stability and reliability of the tensioning member 204 during operation.

[0042] Specifically, the limiting member 205 includes a limiting block 205a that contacts the bottom of the connecting rod 202. A fixing plate 205b is fixedly connected to the bottom of the limiting block 205a. A fixing groove 205c is provided on one side of the fixing plate 205b. A fixing bolt 205d is provided in the inner cavity of the fixing groove 205c. One side of the fixing bolt 205d passes through the fixing groove 205c and is threadedly connected to one side of the inner cavity of the outer shell 101.

[0043] The limiting block 205a contacts the bottom of the connecting rod 202 and is fixed to one side of the inner cavity of the housing 101 by the fixing plate 205b and the fixing bolt 205d. It is used to limit the range of motion of the connecting rod 202, thereby controlling the initial gap between the jaw plate 201 and the impeller 104.

[0044] The limiting block 205a is made of flexible material.

[0045] Specifically, the fixing groove 205c is elongated, and the fixing bolt 205d is located in the center of the inner cavity of the fixing groove 205c.

[0046] The fixing groove 205c is elongated, and the fixing bolt 205d is located in the middle, so that the fixing plate 205b can be finely adjusted within the range of the fixing groove 205c, thereby precisely adjusting the initial gap between the jaw plate 201 and the impeller 104.

[0047] Specifically, there are multiple sets of fixing grooves 205c, which are evenly distributed on one side of the fixing plate 205b.

[0048] Multiple sets of evenly distributed fixing grooves 205c increase stability and allow for more precise setting of the initial gap between the jaw plate 201 and the impeller 104.

[0049] Specifically, the limiting member 205 also includes a limiting bolt 205e disposed on the other side of the housing 101. One side of the limiting bolt 205e penetrates the housing 101 and extends into the housing 101. The limiting bolt 205e cooperates with the jaw plate 201.

[0050] The limit bolt 205e is located on the other side of the housing 101, extending into the housing 101 to cooperate with the jaw plate 201, further limiting the range of motion of the jaw plate 201, and ensuring the safety and stability of the equipment during operation.

[0051] Specifically, the wear part 206 includes a wear-resistant plate 206a that contacts one side of the jaw plate 201. A replacement bolt 206b is provided on one side of the wear-resistant plate 206a. One side of the replacement bolt 206b passes through the wear-resistant plate 206a and is threadedly connected to the jaw plate 201.

[0052] The wear-resistant plate 206a contacts one side of the jaw plate 201 and is fixed by a replacement bolt 206b. When the wear-resistant plate 206a is severely worn, it can be easily replaced, reducing the maintenance cost of the equipment and extending the service life of the jaw plate 201.

[0053] In use, the motor 106 starts, driving the impeller 104 to rotate inside the housing 101. Material enters from the feed chute 102 and is conveyed to the discharge chute 103 under the drive of the impeller 104. When encountering large particles, the large particles squeeze the jaw plate 201. The jaw plate 201 drives the movable rod 204b upward through the connecting rod 202, causing the spring 204d to deform. This increases the gap between the jaw plate 201 and the impeller 104, allowing the large particles to pass through smoothly. After the material passes through, the elastic force of the spring 204d causes the movable rod 204b to reset, and the jaw plate 201 returns to the initial position defined by the limit block 205a. During this process, the first protective plate 105a protects the bearing seat 203, and the second protective plate 105b protects the impeller 104. When the wear-resistant plate 206a wears, it can be replaced by the replacement bolt 206b.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
