Description

Technical Field

[0001] The utility model relates to the technical field of fuel rod molding, in particular to a material receiving mechanism for RDF fuel rod molding. Background Art

[0002] RDF fuel rods are made from waste paper and waste plastics sorted from industrial and domestic waste. They are crushed and molded into solid waste-derived fuel, turning waste into biofuel.

[0003] The Chinese patent with the publication number CN114570502A discloses a receiving mechanism for RDF fuel rods and a method for preparing RDF fuel rods from industrial solid waste, which is used to receive the newly extruded fuel rods. The receiving mechanism includes a discharge extension nozzle, a receiver and a receiving plate. The receiver is installed in a swingable manner corresponding to the position of the discharge extension nozzle. The receiving plate has an inclined conveying surface, and its inclination direction is the same as the unloading and pouring direction of the receiver. The receiving plate is arranged below the discharge extension nozzle. The discharge extension nozzle is used to guide the fuel rod into the receiver. The unloading swinging action of the receiver can be used to intervene in the fuel rod until it breaks while unloading. The receiver forms a slope surface to assist in supporting the fall of the fuel rod when unloading, so as to prevent the fuel rod from falling directly vertically, which can greatly prevent the fuel rod from becoming loose during the production unloading stage.

[0004] However, in the prior art, the fuel rods are extruded from the discharge end as they are stretched and broken under the action of gravity. However, since the breaking time and length are related to the constituent materials, density and humidity of the fuel rods, the fuel rods discharged from several discharge ends are of different lengths. In addition, since the fuel rods are composed of garbage debris, the cross-section surface is uneven when they are broken by gravity pulling, and the debris is easily dropped onto the turntable, which is inconvenient for screening and collection. In view of this problem, the utility model proposes the following improvements. Utility Model Content

[0005] The utility model aims to provide a material receiving mechanism for RDF fuel rod molding, which has the effects of controlling the length of the fuel rod and reducing slag.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a material receiving mechanism for RDF fuel rod molding, comprising a shell, a turntable rotatably connected to the shell and a pressure plate, the pressure plate is provided with a discharge port, a slice is slidably connected to the pressure plate at the discharge port, a spring is arranged between the slice and the pressure plate, and the spring is used to press the slice against the bottom end of the pressure plate; the shell is hinged with a connecting rod, the connecting rod corresponds to the discharge port, a receiving plate is arranged at the end of the connecting rod abutting against the discharge port, a pressing block is arranged at the end of the connecting rod away from the discharge port, the pressing block is used to press the connecting rod against the bottom end of the slice, and the upward movement trajectory of the slice intersects with the discharge port.

[0007] By adopting the above technical solution, by setting the slices and connecting rods, when no fuel rods are placed on the receiving tray, the pressing block presses down the end of the connecting rod away from the discharge port under the action of gravity, and the end of the connecting rod close to the discharge port swings up and contacts the bottom end of the slice, and the connecting rod drives the slice to move upward to cut off the fuel rods at the discharge port. The number of connecting rods and slices is several, the number of pressing blocks is several and the weight is the same, so the time for the connecting rod to swing from the bottom to the top is the same, so the time interval for each cutting of the slices is the same, which can achieve the purpose of controlling the length of the fuel rods and can achieve the purpose of reducing slag.

[0008] The utility model is further configured as follows: the pressing plate is provided with slide grooves on both sides of the discharge port, and sliding blocks are fixedly provided on both sides of the slice, and the sliding blocks are embedded in the slide grooves.

[0009] By adopting the above technical solution, the purpose of the slice being slidably connected in the slide groove through the slider and moving up and down in the slide groove can be achieved.

[0010] The utility model is further configured as follows: the slide groove is provided with a guide rod, the slide block is provided with a guide hole for the guide rod to slide, and the spring is connected to the top end of the slide groove and the top end of the slide block.

[0011] By adopting the above technical solution and setting a guide rod, the slider moves vertically in the slide groove under the action of the guide rod and the guide hole. When the slice is not under force, the spring extends freely and presses the slider against the bottom end of the slide groove, thereby achieving the purpose of the spring pressing the slice against the bottom end of the pressing plate.

[0012] The utility model is further configured as follows: impact blocks are provided at the bottom end of the slice and the end of the connecting rod close to the discharge port.

[0013] By adopting the above technical solution and setting an impact block, the connecting rod can be driven by the impact block when it contacts the slice, and the height of the impact block can be changed according to needs. The height of the impact block is different, and the time interval between the slice and the connecting rod is different, so the length of the obtained fuel rod is also different, which can achieve the purpose of selectively setting the length of the fuel rod.

[0014] The utility model is further configured as follows: the shell is provided with a notch, a first fixed shaft is provided at the notch, and the connecting rod is rotatably connected to the first fixed shaft.

[0015] The utility model is further configured as follows: a blocking block is provided at the lower end of the notch, and the blocking block intersects with the movement trajectory of the connecting rod.

[0016] By adopting the above technical solution and setting a blocking block, when the connecting rod swings downward under the pressure of the fuel rod, the connecting rod first contacts the blocking block, which can prevent the connecting rod from directly hitting the turntable, and when the blocking block contacts the connecting rod, a certain vibration will be generated, and the fuel rods in the receiving tray will more easily slide onto the turntable under the vibration.

[0017] The utility model is further configured as follows: a second fixed shaft is provided at the end of the connecting rod away from the discharge port, and the pressing block is rotatably connected to the second fixed shaft.

[0018] By adopting the above technical solution, by setting a second fixed shaft, the pressing block is rotatably connected to the second fixed shaft and is always vertically downward under the action of gravity. When the connecting rod rotates, the force exerted on the connecting rod at the pressing block remains unchanged, thereby achieving the purpose of ensuring that the gravity of the pressing block is always vertically downward and stabilizing the downward swing of the connecting rod.

[0019] The utility model is further configured as follows: the material receiving tray is in the shape of a pointed bottom pot.

[0020] By adopting the above technical solution, by setting the receiving tray to be a pointed-bottom pot shape, the receiving tray is fixedly installed on the connecting rod. When the end of the connecting rod close to the discharge port swings down, the receiving tray is also in an inclined state. When the receiving tray is inclined, the fuel rods slide along the side wall of the receiving tray and fall onto the turntable, thereby achieving the purpose of smooth unloading of the fuel rods.

[0021] The utility model is further configured as follows: the impact block is made of rubber material.

[0022] By adopting the above technical solution, the rubber materials will not generate loud noise when colliding with each other, and the device will be protected.

[0023] The utility model is further configured as follows: the spring is sleeved on the guide rod.

[0024] By adopting the above technical solution and by putting the spring cover on the guide rod, the spring can be prevented from twisting in the compression direction, thereby achieving the purpose of improving the stability of the spring.

[0025] The beneficial effects of the utility model are as follows: the lengths of several connecting rods are consistent, the masses of several pressing blocks are consistent, the pressing blocks press the connecting rods downward by gravity, the ends of the connecting rods close to the discharge port drive the slices to move upward and cut off the fuel rods, the time from unloading to upward swing of several connecting rods is the same, and the speed of the fuel rods pressed out by the pressing plate at each discharge port is consistent, so the effect of consistent length of the fuel rods can be achieved.

[0032] Embodiment, a material receiving mechanism for RDF fuel rod molding, such as Figure 1-Figure 3As shown, it includes a shell 1, which is circular in shape. A pressing plate 2 and a turntable 3 are coaxially rotated at the center of the shell 1. The pressing plate 2 is located above the turntable 3. A plurality of discharge ports 21 are provided on the outer circumferential surface of the turntable 3. The discharge ports 21 are symmetrically and evenly distributed. Slide grooves 24 are vertically provided on both sides of the discharge port 21. Guide rods 241 are vertically provided in the slide grooves 24. Slide blocks 221 are slidably connected in the slide grooves 24 on both sides. A slice 22 is connected between the slide blocks 221 located on both sides of the discharge port 21. The slice 22 is arranged in an arc shape and is circumscribed to the outer circumferential surface of the pressing plate 2. The slide block 221 is provided with a guide hole 222 for the guide rod 241 to penetrate and slide. A spring 23 is connected to the top of the slide block 221 and the top of the slide groove 24. The spring 23 is jacketed on the guide rod 241. The shell is provided with a plurality of notches 12. The notches 12 are symmetrical and evenly distributed. The notches 12 and the notches 12 are symmetrically and evenly distributed. The dry discharge port 21 corresponds one to one, and a first fixed shaft 121 is provided at the recess 12, and a connecting rod 11 is rotatably connected at the first fixed shaft 121. A receiving tray 111 is fixedly provided at the end of the connecting rod 11 near the discharge port 21, and the receiving tray 111 is arranged in a pointed bottom pot shape, and a second fixed shaft 113 is fixedly provided at the end of the connecting rod 11 away from the discharge port 21, and a pressing block 112 is rotatably connected to the second fixed shaft 113, and a distance between the end of the connecting rod 11 near the discharge port 21 and the first fixed shaft 121 is greater than a distance between the first fixed shaft 121 and the second fixed shaft 113, and a blocking block 122 is fixedly provided on one side of the bottom end of the recess 12 near the discharge port 21, and the blocking block 122 intersects with the motion trajectory of the connecting rod 11, and an impact block 223 is provided at the end of the connecting rod 11 near the discharge port 21 and the bottom of the slice 22, and the impact block 223 is made of rubber material.

[0033] Its working principle is: the pressing block 112 receives the vertical downward gravity and drives the connecting rod 11 to swing around the first rotating shaft, the end of the connecting rod 11 close to the discharge port 21 swings upward, the impact block 223 located on the connecting rod 11 contacts the impact block 223 at the bottom end of the slice 22, and the connecting rod 11 pushes the slice 22 upward. The slice 22 moves upward under the drive of the connecting rod 11 and cuts off the RDF fuel rod at the discharge port 21. After the RDF fuel rod is cut off, it falls into the receiving tray 111.
