Disclosed are a method and device for quantitative granule counting. The device includes a control system, a feeder, a conveyor, a camera, a memory bucket and a trimmer, wherein the control system includes an image processor, a combined computing processor and a PLC; the feeder feeds the conveyor dispersedly, at least one memory bucket is provided under the conveyor according to layers, the camera and image processor acquire image data for the material on the conveyor and analyze and count granules, and the material is transported to the corresponding memory bucket, the number of granules of the material corresponding to the memory bucket; the combined computing processor combines and computes the amount of the material in all the memory buckets, and compares same with a predetermined target granule number, selects a combination of memory buckets that is closest to the target granule number and is within an allowed deviation range, and pulls out the material in the selected memory buckets. The present invention combines the batch CCD granule counting technology in which the number of granules cannot be controlled with the combined computing technology, and therefore the accuracy and speed of quantitative granule counting can be increased significantly.
A: Disclosed is a beltless fully automatic mechanical sampling system for a train. The system comprises: a work platform (1), a sliding rail (11) being provided on the work platform (1); a sampling mechanism (2) slidably arranged on the sliding rail (11) and configured to collect materials from a carriage (13) of the train; and an integrated sample preparation assembly (100) comprising a reject flowback mechanism (6), and a feeder (3), a crusher (4), a fixed mass divider (5) and a sample retention barrel (7) sequentially arranged from top to bottom, wherein the feeder (3) is configured to deliver the material to the crusher (4), the crusher (4) is configured to crush the material and deliver the crushed material to the fixed mass divider (5), the fixed mass divider (5) is configured to divide the crushed material into a sample and a reject, deliver the sample to the sample retention barrel (7) and deliver the reject to the reject flowback mechanism (6), and the reject flowback mechanism (6) is configured to deliver the reject to the carriage (13).
B: Disclosed is a material-conveying device, comprising: a conveying mechanism (1); material storage mechanisms respectively arranged at at least one end of the conveying mechanism (1) in a conveying direction; and a taking and placing mechanism (3) moving along the conveying mechanism (1), wherein the taking and placing mechanism (3) comprises at least two material temporary storage areas, the material temporary storage areas comprising a feeding temporary storage area (31) and a return material temporary storage area (32). Any temporary storage area can achieve temporary storage in feeding and returning processes. If feeding needs to be carried out for two production apparatuses, the conveying mechanism (1) only needs to drive the taking and placing mechanism (3) to sequentially move to a position close to the corresponding production apparatus, materials in the feeding temporary storage area (31) are placed in the corresponding apparatus, and the material-conveying device is coordinated with a plurality of production apparatuses to realize production line cooperation, such that the production efficiency is improved.
C: Disclosed are an organic waste liquid self-sustaining smoldering continuous reaction device and a reaction method. The reaction device comprises a smoldering furnace, a stirrer (12), a conveying mechanism (13), a feeder (10), a discharging device (11) and a controller, wherein the smoldering furnace is used as a combustion chamber of the reaction device; the stirrer (12) is used for mixing organic liquid slurry to be treated with sand; the conveying mechanism (13) conveys stirred materials into the smoldering furnace; the feeder (10) and the discharging device (11) are used for inputting and outputting the materials into/from the smoldering furnace; and the controller is used for monitoring the smoldering surface and the temperature in the smoldering furnace in real time, and accordingly controlling the combustion process in the smoldering furnace so as to ensure continuous smoldering operation, uninterrupted supply of materials, recycling of sand and real-time monitoring of the temperature, such that batch treatment of organic waste liquid can be realized, and the demand in the market for the high-efficiency treatment of organic waste liquid slurry is met.
D: A method and a device for dispensing discrete articles. Said method comprises: driving a conveyor (1) to convey articles; the articles outputted by the conveyor (1) in one start-stop period forming at least one individual article stack; performing continuous image acquisition on one image acquiring region (201) which is located at an end section of the conveyor (1); processing the acquired images in real time so as to determine the number of outputted articles; and searching for one combined article stack, the number of articles of each combined article stack being the same as a target number, and dispensing one combined article stack to a container (6). As the image acquiring region is provided across the output end section of the conveyor, and image acquisition and counting can be completed without a detection platform or a counting platform, the length of the present conveyor is reduced as compared with a conveyor having a detection platform or a counting platform, etc., simplifying the structure, and saving space.
