Description

Technical Field

[0001] The utility model relates to a material feeding device, in particular to a material feeding device with constant pressure feeding. Background Art

[0002] With the requirements of garbage classification collection and classification disposal, the degree of garbage reduction and resource utilization needs to be continuously improved. As the front-end link of garbage treatment, the pretreatment stage is crucial for the subsequent anaerobic and sewage treatment processes. As the most front-end equipment in the pretreatment process, the design optimization of the material receiving device is of decisive significance for the overall process plan layout, operation process flow, and plant processing capacity. With the development of urban construction and the improvement of automation, the demand for temporary storage of garbage entering the factory is increasing. However, if a garbage storage pool is set up, it not only occupies 1 / 4 of the factory area but also requires additional grab cranes, deodorization, and wastewater recovery equipment, greatly increasing the investment and operating costs. Therefore, the process design requires a larger and larger design volume for the silo to be used as the temporary storage of materials, resulting in an increasing stacking height. Generally, the bottom discharging equipment is a spiral plate chain conveyor or the like. As the height of the materials increases, the pressure generated by the material stacking also increases, which is a test for the required power, strength, and operating stability of the equipment.

[0003] For conventional large silos for solid materials with good fluidity or loose particles, a pressure relief plate or pressure relief angle steel will be made near the discharge port. However, due to the poor fluidity and easy entanglement characteristics of materials such as food waste, it is impossible to set up a pressure relief plate according to the conventional solid silo. Therefore, with the increasing material pressure, equipment failures such as broken shaft motor burnout or material blockage frequently occur. Summary of the Utility Model

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a material feeding device with constant pressure feeding to solve the influence of material stacking pressure on the conveying equipment. At the same time, it also has the effect of stably controlling the material conveying volume and reducing the power required for conveying materials, thereby not only ensuring the normal operation of the equipment but also saving the operating cost and breaking through the limitation of the volume of the material receiving device.

[0005] The utility model provides the following technical solutions:

[0006] A material feeding device with constant pressure feeding includes a silo arranged above a feeding conveyor. A material feeding mechanism for pressure relief is arranged in the silo. The material feeding mechanism includes a material feeding body in the shape of a straight prism, multiple groups of material feeding scrapers arranged corresponding to each group of side edges of the material feeding body, and a rotating motor installed on the silo and passing through the silo to be connected to both ends of the material feeding body for driving the material feeding body to rotate.

[0007] In the device of the utility model, because a straight prism-shaped material-dispensing body is adopted, that is, the material-dispensing body has a polygonal cross-section, it can produce a material-dispensing effect when rotating, which plays a role in loosening the material; and the installation of the material-dispensing scraper can prevent the material from being entangled while dispensing the loose material during operation, further playing a loosening role and preventing the material from bridging. Thus, this design solves the problem of large-scale silo materials with high accumulation pressure and easy entanglement during the decompression process, which causes bridging of materials; and due to the reduction of material conveying resistance, the power of the conveyor part will be greatly reduced, and the strength requirements of the equipment itself will be reduced accordingly. Due to the decompression and feeding effect of the material-dispensing decompression device, the conveying stability is also greatly improved, avoiding the occurrence of material bridging and blockage.

[0008] Preferably, the material-shifting scraper is also in the shape of a regular prism, and a plurality of scraper units are distributed along its side edges, and the plurality of material-shifting scraper units distributed along the circumferential direction are combined into a group of scraper units, so as to improve the material-shifting decompression effect.

[0009] Preferably, the material-digging mechanism is provided with a plurality of groups and is distributed in parallel in the silo in a double-layer distribution arrangement, and the number of the material-digging mechanisms located on the upper layer is one group more than the number of the material-digging mechanisms located on the lower layer, the material-digging mechanisms located on the upper layer and the material-digging mechanisms located on the lower layer are staggered with respect to each other, and the material-digging mechanisms located on the upper layer and the material-digging mechanisms located on the lower layer both have at least two groups of adjacent material-digging mechanisms rotating in opposite directions, so as to improve the material-digging decompression effect.

[0010] Preferably, one end of the material-moving scraper is locked on the material-moving body through a scraper connector, and the other end is an inwardly concave arc shape, and two sets of serrated grooves are provided at both ends of the arc shape, so that while moving the loose material during operation, the material can be further prevented from being entangled.

[0011] Preferably, the material-dispensing body comprises a plurality of sections of prism units that are butt-jointed at the ends, a plurality of groups of column holes are provided at both ends of each section of the prism unit, and two adjacent groups of prism units are connected and positioned by a plurality of groups of columnar positioning pins inserted in the column holes. When local maintenance is required at a later stage, it can be carried out by replacing the prism units, which is more convenient and easy.

[0012] The beneficial effects of the utility model are as follows: the device of the utility model can be applied to garbage classification collection and transportation and classification disposal, the silo is used to receive materials, the material accumulation pressure acts on the material-discharging mechanism used for reducing pressure, after the material-discharging mechanism is operated, the materials enter the feeding conveyor, and the feeding conveyor is fed outward, and by controlling the running speed of the material-discharging mechanism, the material-incoming rate of the conveyor can be ensured to be uniform, and the filling density is consistent, so the conveying resistance and the conveying amount can be effectively controlled;

[0013] In the device of the present utility model, the main functions of the material feeding mechanism include: firstly, bearing the material accumulation load and not directly applying all the material loads to the conveying part of the equipment; secondly, feeding the material to the conveyor according to the required conveying volume. The design features are as follows: the material feeding body with a polygonal cross-section can generate a material feeding effect during rotation, playing a role in loosening the material; the specially designed material feeding scraper can prevent the material from winding while loosening the material during operation, further playing a role in loosening and preventing the material from bridging. Thus, through this design, the problems of large material accumulation pressure in large bins and blockage and bridging of easily wound materials during the pressure reduction process are solved.

[0014] Due to the reduction of the material conveying resistance, the power of the conveyor part will be greatly reduced, and at the same time, the strength requirement of the equipment itself will be reduced accordingly. Due to the pressure reduction and feeding effect of the material feeding and pressure reduction device, the conveying stability is also greatly improved, avoiding the occurrence of material bridging and blockage.

[0015] The device of the present utility model can solve the problems such as easy failure of the feeding conveyor of the receiving device, conveying blockage, and unstable conveying volume, reduce the power required for equipment feeding, save the operation cost, break through the limitation of the volume of the receiving device, and the device of the present utility model has a simple structure, low cost, and reliable performance, greatly reducing the maintenance cost of the equipment and the production line, and ensuring the smooth operation of the production line and good economic performance.

[0026] Embodiment 1

[0027] As Figures 1-5 shown, a material feeding device for constant pressure feeding. In this embodiment, it includes a silo arranged above the feeding conveyor. A material feeding mechanism for pressure reduction is arranged in the silo. The material feeding mechanism includes a feeding body in the shape of a straight prism, multiple groups of feeding scrapers arranged corresponding to each group of side edges of the feeding body, and a rotating motor installed on the silo and passing through the silo to be connected to both ends of the feeding body for driving the feeding body to rotate;

[0028] In the device of the present utility model, because a feeding body in the shape of a straight prism is adopted, that is, the feeding body has a polygonal cross-section, thus, a feeding effect can be generated during rotation, playing a role in loosening the material; and the installation of the feeding scrapers can, while loosening the material during operation, also prevent the entanglement of the material, further playing a role in loosening and preventing the material from bridging. Thus, through this design, the problems of large material accumulation pressure in a large silo and the blockage and bridging of easily entangled materials during the pressure reduction process are solved; and due to the reduction of the material conveying resistance, the power of the conveyor part will be greatly reduced, and at the same time, the strength requirement of the equipment itself will be reduced accordingly. Due to the pressure reduction and feeding effect of the material feeding and pressure reduction device, the conveying stability is also greatly improved, avoiding the occurrence of material bridging and blocking situations.

[0029] The feeding scraper is also in the shape of a regular prism, and multiple groups of scraper units are also distributed along its side edge direction, and multiple groups of feeding scrapers distributed in the circumferential direction form a group of scraper units to improve the feeding and pressure reduction effect.

[0030] Multiple groups of the material feeding mechanism are provided and are parallelly distributed in the silo. It is arranged in a double-layer manner, and the number of the material feeding mechanisms in the upper layer is one more than that in the lower layer. The material feeding mechanisms in the upper layer and the lower layer are staggeredly distributed with each other. At least two adjacent material feeding mechanisms in the upper layer and the lower layer rotate in opposite directions to improve the feeding and pressure reduction effect.

[0031] One end of the material-moving scraper is locked on the material-moving body through a scraper connector, and the other end is an inwardly concave arc shape, and two sets of serrated grooves are provided at both ends of the arc shape, so that while moving the loose materials during operation, the entanglement of the materials can be further prevented.

[0032] Example 2

[0033] like Figures 6-7 As shown, a material dispensing device for constant pressure feeding, in this embodiment, is further limited based on Example 1, the material dispensing body includes a plurality of sections of prism units with butt joints at the ends, a plurality of groups of column holes are provided at both ends of each section of the prism unit, and two adjacent groups of prism units are connected and positioned by a plurality of groups of columnar positioning pins inserted in the column holes. When local maintenance is needed at a later stage, it can be carried out by replacing the prism unit, which is more convenient and easy.

[0034] The working principle of the utility model is as follows: the device of the utility model can be applied to garbage classification collection and transportation and classification disposal. The silo is used to receive materials, and the material accumulation pressure acts on the material-dispensing mechanism used for decompression. After the material-dispensing mechanism is in operation, the materials enter the feeding conveyor and are fed outward by the feeding conveyor. By controlling the running speed of the material-dispensing mechanism, the uniform material rate of the conveyor and the consistent filling density can be ensured, so the conveying resistance and the conveying volume can be effectively controlled; the design features of the device of the utility model are as follows: the material-dispensing body with a polygonal cross section can produce a material-dispensing effect when rotating, which plays a role in loosening the materials; the specially designed material-dispensing scraper prevents the entanglement of the materials while dispensing the loose materials during operation, further plays a loosening role, and prevents the materials from bridging. Thus, this design solves the problem of large silo materials with large accumulation pressure and easy entanglement during the decompression process, which causes the blocking and bridging phenomenon; due to the reduction of the material conveying resistance, the power of the conveyor part will be greatly reduced, and the strength requirements of the equipment itself will be reduced accordingly. Due to the decompression and feeding effect of the material-dispensing decompression device, the conveying stability is also greatly improved, which avoids the occurrence of material bridging and blocking.
