[0041] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0042] like Figure 1 The figure is a schematic diagram of the structure of an alternative fuel storage and feeding device according to one embodiment of the present invention. Figure 1 In the figure, the alternative fuel storage and feeding device includes a storage bin 1, a conveying mechanism 2, a dispersing and retrieving mechanism 3, a monitoring scale 4, a material level radar 5 and a controller (not shown in the figure); specifically, a feed port 11 is provided at one end of the top of the storage bin 1, and a discharge port 12 is provided at the other end of the bottom of the storage bin 1, and an opening (not shown in the figure) is provided at the bottom of the storage bin 1, and the conveying mechanism 2 can be provided below the storage bin 1 along the length direction of the storage bin 1, and the top of the conveying mechanism 2 is matched and sealed with the opening of the storage bin 1, so that the conveying mechanism 2 can serve as the bottom surface of the storage bin 1 for receiving materials, and the dispersing and retrieving mechanism 3 can be laterally fixedly connected to the other end of the storage bin 1. The two side walls, and the other end close to the conveying mechanism 2, are arranged above the discharge port 12, and the conveyed materials can be directly dispersed and taken to avoid material agglomeration and blockage. The monitoring scale 4 can be arranged on the discharge port 12, and is used to monitor and record the discharge flow rate and discharge weight of the material in real time. The material level radar 5 can be arranged in the middle of the top of the storage silo 1, and is used to scan and record the status information of the materials on the storage silo 1 and the conveying mechanism 2. The controller can be electrically connected to the conveying mechanism 2, the dispersing and taking mechanism 3, the monitoring scale 4 and the material level radar 5, integrate the status information of the received materials, and adjust the working speed of the conveying mechanism 2 in real time to achieve stable feeding and discharge flow calibration of the materials.

[0043] The storage and feeding device is configured with a sealed connection between a storage bin and a conveying mechanism, so that the material is conveyed through a conveyor to avoid clogging of the bin. At the same time, a dispersing and taking device is provided to disperse and convey the material from bottom to top to avoid uneven material feeding. A controller is provided to process real-time conveying information of the material monitored by a monitoring scale and a material level radar. A material thickness regulator is provided to control the material thickness on the conveying mechanism, adjust the conveying speed of the conveying mechanism, improve the stability and accuracy of the discharge metering, and ensure the rational use of alternative fuels.

[0044] exist Figure 1 In order to control the thickness of the material in the storage bin 1 and avoid the fluctuation of the material on the conveying mechanism 2, in one embodiment of the present invention, the storage feeding device may include a material thickness regulator 6, which is electrically connected to the controller and is arranged in the middle of the top of the storage bin 1 near the feed port 12, for adjusting the thickness of the material; in order to facilitate the smoothing control of the material, in one embodiment of the present invention, the material thickness regulator 6 includes an electric push rod 61 and a baffle 62, and the electric push rod 61 is electrically connected to the controller; the baffle 63 can be hinged under the feed port 11 and fixedly connected to the electric push rod 61, so that the controller adjusts the electric push rod 61 to control the discharge thickness of the material from the storage bin, and at the same time the baffle 62 can press and smooth the material, reduce the fluctuation of the material layer, ensure that the discharge volume of the material is controlled within the set range, and achieve stable feeding.

[0045] In order to avoid the formation of a material arch in the storage silo body 1 that hinders the discharge of materials, in one embodiment of the present invention, the aspect ratio of the storage silo body 1 is less than 1.5, and the side walls of the storage silo body 1 are vertically connected to the top of the conveying mechanism 2. The vertical setting of the side walls and the low aspect ratio can effectively prevent the material from forming a material arch in the storage silo body 1, thereby ensuring smooth discharge of materials.

[0046] In order to facilitate the injection, in one embodiment of the present invention, the feed port 11 may be trumpet-shaped outwardly, so as to prevent the material from overflowing during the injection process and ensure the safety and stability of the injection.

[0047] Taking into account that the conveying mechanism 2 will drive the material to move during the conveying process to avoid the overflow of the material, in one embodiment of the present invention, the width of the conveying mechanism 2 is greater than the width of the storage bin body 1, so that the gap between the conveying mechanism 2 and the storage bin body 1 can be sealed by setting a vertical plate to ensure the safety of the conveying of the conveying mechanism 2; at the same time, it is avoided that the material on the conveying mechanism 2 is relatively displaced, which affects the precise measurement of material transportation and ensures the stability of the material transportation. In one embodiment of the present invention, the conveying mechanism 2 can be provided with a rubber belt surface 21, and the rubber belt surface 21 is connected to the conveying mechanism 2 by transmission to avoid the relative displacement of slipping between the rubber belt surface 21 and the conveying mechanism 2, so as to prevent the material speed adjustment during precise feeding from being affected, and a plurality of groups of scraping angle steels 22 are arranged on the rubber belt surface 21 at intervals. The rubber belt surface 21 and the scraping angle steels 22 can increase the friction with the material, ensure the relative stillness of the conveying mechanism 2 and the material, prevent relative sliding, and improve the stability of the material transportation.

[0048] In order to meet the controller's speed regulation during material transportation and ensure the accurate transportation of materials per unit time, in one embodiment of the present invention, the speed of the conveying mechanism 2 is frequency-controlled, so that the working speed of the conveying mechanism 2 can be adjusted arbitrarily according to the control of the controller, thereby improving the accuracy of material transportation; at the same time, considering that the information feedback of the material level radar 5 and the monitoring scale 4 can realize the calibration of accurate feeding and discharge flow, in one embodiment of the present invention, the material fluctuates during the feeding and movement process, resulting in certain irregularities in the shape of the material. The material level radar 5 can be used to scan and record the cross-sectional area of ​​the material to be entered at the discharge port, and the monitoring scale 4 is used to monitor and record the discharge flow of the material per unit time.

[0049] In order to realize the calibration of stable feeding and discharging flow rate by the controller, in one embodiment of the present invention, the controller can be used to obtain the cross-sectional area of ​​the material, adjust the discharging speed of the material according to the cross-sectional area and formula (1) and formula (2), adjust the moving speed of the conveying mechanism according to formula (1) to ensure stable feeding, and obtain the real-time discharging flow rate according to the monitoring scale, and adjust the correction coefficient of formula (1) according to formula (2) to realize the calibration of the discharging flow rate.

[0050]

[0051] Among them, u t is the moving speed of the material at time t, m0 is the preset discharge flow rate, a is the calculation constant, ρ is the average density of the material, d t is the cross-sectional area of ​​the material at time t, K is the correction coefficient, K t is the correction coefficient at time t, m t is the discharge flow rate at time t.

[0052] During the conveying process, accurate feeding is ensured in real time, the cross-sectional area of ​​the material is scanned in real time, and the discharge flow rate per unit time is determined to be stable, so as to determine the moving speed of the conveyed material according to formula (1). The moving speed of the material can be achieved by controlling the conveying mechanism 2. At this time, the initial value of K is 1. When conveying materials, flow calibration is started only when the real-time discharge flow rate is detected at the discharge port. Therefore, there is no need to increase the correction coefficient of the time interval for calibration. The real-time correction coefficient is obtained according to the real-time discharge flow rate and the preset discharge flow rate, so that the discharge flow rate calibration can be directly performed.

[0053] Considering the physical properties of the material, the material is easy to agglomerate and needs to be dispersed. In order to improve the dispersion efficiency and meet the reasonable use of it as an alternative fuel, in one embodiment of the present invention, the dispersing and taking material mechanism 3 is a roller 31, and the roller 31 is provided with multiple sets of material-dispensing plates 32, which can be used to open and disperse the material. At the same time, in order to ensure that the front end of the material can be fully dispersed during the conveying process and ensure the production safety of the dispersed material, in one embodiment of the present invention, the projection part of the roller 31 and the material-dispensing plate 32 covers the other end of the conveying mechanism 2, and the height of the material-dispensing plate 32 located at the top of the roller 31 is higher than the height of the material, so that the roller 31 can always carry the material from the bottom to the top and fall into the discharge port 12 from the top of the roller 31 to ensure sufficient dispersal. The other end of the storage bin 1 is provided with a shielding plate 13 to avoid splashing of the material during the dispersal process, prevent the splashed material from causing safety hazards to production, and improve the safety of production work.

[0054] Through the above technical scheme, the storage feeding device is provided with a sealed connection between the storage bin and the conveying mechanism, so that the material is conveyed through the conveyor, and the width of the conveying mechanism is greater than the width of the storage bin to avoid side leakage of the material, and to ensure that the material in the bin moves forward as a whole; the storage bin with a low aspect ratio is adjusted to avoid material racking and silo blockage; at the same time, a dispersing and picking device is provided to disperse and convey the material from bottom to top to avoid uneven discharge, and the dispersing and picking mechanism is provided as a roller, and a plurality of groups of material shifting plates are provided on the roller, and the material shifting plates can disperse the material so that the material is dispersed from bottom to top and falls on the discharge port; and a controller is provided to process the real-time conveying information of the material monitored by the monitoring scale and the material level radar, and a material thickness regulator is provided to control the material thickness on the conveying mechanism, and the material is smoothed by the baffle of the material thickness regulator to avoid material layer fluctuation, and the conveying speed of the conveying mechanism is regulated to ensure the stability and accuracy of the discharge metering, and ensure the rational use of alternative fuels.
