Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to an automated metering feeding device. Background Technology

[0002] In the production of yellow phosphorus, the metering, mixing, and feeding of raw materials have a crucial impact on product quality and production efficiency.

[0003] Currently, traditional methods of metering raw materials for yellow phosphorus production primarily utilize ton-scale weighing, requiring manual operation by meter readers. Specifically, in the metering process, meter readers must manually measure each type of raw ore individually; material discharge is also done manually; and the mixing process relies on manual operation. This complex manual operation method has many drawbacks. On the one hand, it is difficult to operate, requiring a high level of professional skills and experience from the meter readers; on the other hand, the extensive manual operation not only consumes a significant amount of physical strength but also requires considerable mental effort to ensure the accuracy of the operation and the correctness of the process.

[0004] Moreover, manual operation is relatively inefficient and cannot meet the needs of large-scale, continuous production. Furthermore, manual operation is prone to errors, which may lead to inaccurate measurement of raw materials, thereby affecting the production quality and stability of yellow phosphorus.

[0005] With the continuous development and progress of industrial automation technology, in order to improve the efficiency of yellow phosphorus production, reduce labor intensity, and ensure the stability of product quality, there is an urgent need for an automated metering, mixing, and feeding equipment that can replace the manual operation of traditional metering weighing. This equipment can realize the automatic and continuous operation of the entire process of unloading various raw materials from the silo, weighing them according to process indicators, and mixing them in sequence, thereby achieving the economic benefits of reducing manpower and increasing efficiency. Summary of the Invention

[0006] The technical problem to be solved by this utility model is that the current method of manually weighing and mixing materials is not only inefficient and labor-intensive, but also prone to errors that affect product quality and stability.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an automated metering and feeding device, including a weighing and unloading component arranged at equal intervals along the feeding belt. The weighing and unloading component includes a receiving hopper and a weighing belt scale. The receiving hopper is located above the weighing belt scale and is connected to a storage hopper for raw materials through a pipe. The unloading end of the weighing belt scale is connected to the feeding belt through a guide plate. The weighing belt scale is driven by a variable frequency motor.

[0008] Preferably, the weighing and unloading assembly includes a housing covering the weighing belt scale, a receiving hopper fixedly connected to the top of the housing, a dust removal pipe connected to the top of the housing, and a bag filter connected to the dust removal pipe, with the dust removal pipe located above the unloading end of the weighing belt scale.

[0009] Preferably, the receiving hopper is inverted conical in shape, and the bottom end of the receiving hopper is provided with a notch on the side near the weighing belt scale. The discharge end of the weighing belt scale is connected to a guide plate, and the guide plate is provided with a diversion structure to disperse the raw material accumulated in the middle of the belt on the weighing belt scale.

[0010] Preferably, the flow splitting structure is a flow splitting plate vertically fixed to the top of the guide plate, the flow splitting plates are distributed in a fan shape, and the spacing between adjacent flow splitting plates increases from top to bottom.

[0011] Preferably, the top of the guide plate contacts the bottom of the belt at the unloading end of the weighing belt scale, and the top of the guide plate is provided with a notch to accommodate the unloading end of the weighing belt scale.

[0012] Preferably, a baffle is provided between the bottom end of the feed belt and the guide plate. The baffle is located on both sides of the feed belt, and is arranged at an angle. The top end of the baffle is located on the outer side of the feed belt, and the bottom end of the baffle is located on the inner side of the feed belt.

[0013] Preferably, the bottom of the feed belt is provided with a concave support roller seat, and support rollers are rotatably arranged on the inner top and inner sides of the support roller seat. The bottom and sides of the feed belt are respectively in contact with the corresponding support rollers. The support roller seats are distributed along the feed belt, and multiple sets of support roller seats are provided directly below the unloading end of the weighing belt scale.

[0014] This utility model provides an automated metering and feeding device, which has the following beneficial effects.

[0015] 1. The weighing and feeding components are set at equal intervals along the feeding belt.

[0026] like Figure 1-5 As shown, this utility model provides an automated metering and feeding device, including a weighing and unloading assembly arranged at equal intervals along the feeding belt 8. The weighing and unloading assembly includes a receiving hopper 5 and a weighing belt scale 9. The receiving hopper 5 is located above the weighing belt scale 9. The receiving hopper 5 is connected to the raw material storage hopper 2 through a pipe. The unloading end of the weighing belt scale 9 is connected to the feeding belt 8 through a guide plate 10. The weighing belt scale 9 is driven by a variable frequency motor.

[0027] A spiral feed cylinder 3 is horizontally fixed at the pipe opening at the bottom of the discharge hopper 2. The auger is driven by a motor to rotate, conveying the raw materials entering the feed end of the spiral feed cylinder 3 to the discharge end of the spiral feed cylinder 3. The discharge end of the spiral feed cylinder 3 is connected to the discharge pipe 4, which is connected to the receiving hopper 5. The raw materials are conveyed to the receiving hopper 5 through the spiral feed cylinder 3. After passing through the receiving hopper 5, the raw materials fall onto the belt inside the weighing belt scale 9. The weighing belt scale 9 is an existing belt scale that can continuously weigh bulk materials on the conveyor belt. The belt is driven to rotate by a variable frequency motor. The operator controls the feeding of the weighing belt scale 9 according to the proportion of raw materials. Since multiple raw materials are directly fed onto the feed belt 8, they can be initially mixed on the feed belt 8. After that, the raw materials are conveyed to the next process for processing through the feed belt 8.

[0028] like Figure 1 and Figure 2 As shown. The weighing and feeding assembly includes a housing 1 covering the weighing belt scale 9, a receiving hopper 5 fixedly connected to the top of the housing 1, a dust removal pipe 6 connected to the top of the housing 1, and a bag filter connected through the dust removal pipe 6. The dust removal pipe 6 is located above the feeding end of the weighing belt scale 9.

[0029] Since dust is generated during the production process, in order to improve the working environment and reduce the impact of dust on the equipment, the receiving hopper is fixedly connected to the top of the housing 1. The receiving hopper 5 and the discharge pipe 4 are connected by a flange structure to form a sealed conveying pipe, which is connected to the inside of the housing 1 through a bag dust collector and a dust collection pipe 6. In actual operation, when the weighing belt scale 9 performs the discharge operation, the dust collection pipe 6 located above the discharge end will suck in the generated dust and filter it through the bag dust collector.

[0030] like Figure 2 and Figure 5 As shown. The receiving hopper 5 is inverted conical in shape, and a notch is provided at the bottom of the receiving hopper 5 near the weighing belt scale 9. The discharge end of the weighing belt scale 9 is connected to a guide plate 10, which is provided with a diversion structure to disperse the raw material accumulated in the middle of the belt on the weighing belt scale 9. When the lumpy raw material in the storage hopper 2 enters the receiving hopper 5 through the pipe, due to the inverted conical structure of the receiving hopper 5, the raw material will naturally converge towards the bottom and fall into the middle of the weighing belt scale 9, preventing the raw material from falling through the gap between the weighing belt scale 9 and the shell or getting stuck in the gap. The notch at the bottom of the receiving hopper 5, under the action of the inclined plate on the opposite side of the notch, will cause the raw material to move in the direction of the belt rotation in the weighing belt scale 9, which can prevent the material from moving in the opposite direction due to discharge and falling from the other end of the weighing belt scale 9 when the top of the weighing belt scale 9 is relatively short, thereby improving the accuracy of batching.

[0031] like Figure 2 and Figure 4As shown. The diversion structure is a diversion plate 12 vertically fixed to the top of the guide plate 10. The diversion plates 12 are distributed in a fan shape, and the spacing between adjacent diversion plates 12 increases from top to bottom. Since the raw materials are gathered in the middle of the weighing belt scale 9 when weighing and transporting the raw materials, the accumulation and falling of the raw materials will cause a large impact on the feed belt 8. Therefore, the diversion plate 12 is set up so that when the raw materials pass through the guide plate 10, they are dispersed by the diversion plate 12 and fall evenly onto the feed belt 8.

[0032] like Figure 2 and Figure 4 As shown. The top of the guide plate 10 contacts the bottom of the belt at the discharge end of the weighing belt scale 9, and the top of the guide plate 10 is provided with a notch to accommodate the discharge end of the weighing belt scale 9. The guide plate 10 abuts against the bottom of the discharge end of the weighing belt scale 9, so that the raw material can be smoothly transferred from the belt to the guide plate 10 when it is discharged from the weighing belt scale 9, and then conveyed to the feed belt 8.

[0033] like Figure 3 As shown in the diagram, a baffle 11 is provided between the bottom end of the feed belt 8 and the guide plate 10. The baffle 11 is located on both sides of the feed belt 8, and is arranged at an angle. The top end of the baffle 11 is located on the outer side of the feed belt 8, and the bottom end of the baffle 11 is located on the inner side of the feed belt 8. Since the guide plate 10 adopts a decentralized feeding method during the feeding process, and the guide plate 10 needs to maintain a sufficient gap with the feed belt 8 to avoid interference with the raw materials on the feed belt 8, the baffle 11 is set to prevent the raw materials from popping out of the feed belt 8 when they fall onto the feed belt 8, thus reducing material waste while ensuring the cleanliness of the working area.

[0034] like Figure 1-3 As shown. The bottom of the feeding belt 8 is provided with a concave support roller seat 7. Support rollers are rotatably arranged on the inner top and both inner sides of the support roller seat 7. The bottom and sides of the feeding belt 8 respectively contact the corresponding support rollers. The support roller seats 7 are distributed along the feeding belt 8, and multiple sets of support roller seats 7 are arranged directly below the material discharge end of the weighing belt scale 9. At least two support roller seats 7 are provided at the material receiving position of the feeding belt 8 to ensure the stability of the feeding belt 8's operation. A mounting frame is provided at the bottom of the support roller seat 7, and the mounting frame is set parallel to the feeding belt 8. The bottom of the support roller seat 7 is bolted to the mounting frame. The mounting frame has evenly distributed bolt holes for easy adjustment of the support roller seat 7's position.
