Description
技术领域Technical field
本实用新型总体涉及颗粒检测领域，更具体地，本实用新型涉及一种颗粒度检测系统。The utility model generally relates to the field of particle detection, and more specifically, the utility model relates to a particle size detection system.
背景技术Background technique
在颗粒状产品(尤其是面粉等粉状产品)加工生产过程中，对于产品的颗粒度大小的检测有利于对生产工艺流程做出相应的调整，有效提高生产效率、避免造成不必要的浪费。During the processing and production of granular products (especially powdery products such as flour), the detection of the particle size of the product is helpful to make corresponding adjustments to the production process, effectively improve production efficiency and avoid unnecessary waste.
目前，面粉加工行业的颗粒度检测手段相对落后，主要通过人工手捏、肉眼观察或离线实验室筛分的方法判断颗粒是否合格，进而调节相关生产工艺参数，导致产品质量可控性较低。At present, the particle size detection methods in the flour processing industry are relatively backward. They mainly use manual hand crushing, naked eye observation or offline laboratory screening to determine whether the particles are qualified, and then adjust relevant production process parameters, resulting in low product quality controllability.
例如，传统离线检测是每间隔3～4小时去生产现场取样一次，然后拿到实验室分析仪器上进行筛分。这种方法的缺点为需要人工手动取样，取样稳定性较差，取样筛分时间长，检测结果比生产滞后，导致对生产的指导作用不及时，增加了出现不合规格产品的概率，不能适应现代技术发展对生产过程及产品质量的要求。For example, traditional offline testing requires sampling at the production site every 3 to 4 hours, and then taking it to the laboratory analysis instrument for screening. The disadvantages of this method are that manual sampling is required, the sampling stability is poor, the sampling and screening time is long, and the detection results lag behind the production, resulting in untimely guidance for production, increasing the probability of substandard products, and cannot adapt to modern times. Technological development requires production processes and product quality.

The particle size detection system includes a sampling subsystem 1, an analysis subsystem 2, a recovery subsystem 3, a power subsystem 4 and a control subsystem 5.

取样子系统1包括适于连接至颗粒状或粉状产品生产线的多个取样点。在多个取样点处分别设置有多个取样器111以分别对生产线上多个位置的颗粒状或粉状产品进行取样。其中，每个取样器111的取样料斗1111收集从生产线上落下的颗粒状或粉状产品，依靠压缩空气推动气缸活塞杆运动，从而带动取样器111内的活塞116刮取颗粒状或粉状产品。在每个取样器111的出口端连接有取样管道112。取样管道112包括主物料管道1121和并联设置的多个分物料管道1122。其中，多个分物料管道1122中的每个的一端连接至对应的取样器111，另一端连接至主物料管道1121，每次开启至少一个分物料管道1122的同时关闭其他分物料管道1122。主物料管道1121上设置有观察窗口113以便于观察管道内颗粒状或粉状产品的状态。The sampling subsystem 1 includes a plurality of sampling points suitable for connection to a granular or powdery product production line. Multiple samplers 111 are respectively provided at multiple sampling points to sample granular or powdery products at multiple locations on the production line. Among them, the sampling hopper 1111 of each sampler 111 collects granular or powdery products falling from the production line, and relies on compressed air to push the cylinder piston rod to move, thereby driving the piston 116 in the sampler 111 to scrape the granular or powdery products. . A sampling pipe 112 is connected to the outlet end of each sampler 111 . The sampling pipeline 112 includes a main material pipeline 1121 and a plurality of sub-material pipelines 1122 arranged in parallel. One end of each of the plurality of sub-material pipes 1122 is connected to the corresponding sampler 111, and the other end is connected to the main material pipe 1121. Each time at least one sub-material pipe 1122 is opened, other sub-material pipes 1122 are closed. An observation window 113 is provided on the main material pipeline 1121 to facilitate observation of the state of granular or powdery products in the pipeline.
可以理解，分物料管道1122和主物料管道1121的数量和布置方式根据实际需要确定，本实用新型对此不作限制。例如，根据所示的实施方式，设置一条大致沿水平方向布置的主物料管道1121和九条大致沿竖直方向并联布置的分物料管道1122。例如，也可以设置多条并联的主物料管道1121，每条主物料管道1121上并联设置数量相同或不同的分物料管道1122。根据一种实施变型，主物料管道1121也可以根据实际情况布置为弯折形状，本实用新型对此不做限制。It can be understood that the number and arrangement of the sub-material pipes 1122 and the main material pipes 1121 are determined according to actual needs, and the present invention does not limit this. For example, according to the illustrated embodiment, one main material pipe 1121 arranged generally in the horizontal direction and nine sub-material pipes 1122 arranged generally in parallel in the vertical direction are provided. For example, multiple parallel main material pipelines 1121 may also be provided, and each main material pipeline 1121 may be provided with the same or different number of sub-material pipelines 1122 in parallel. According to an implementation variation, the main material pipe 1121 can also be arranged in a bent shape according to actual conditions, and the present invention does not limit this.
如图2和图4所示，每个取样器111包括进料口111a、第一出料口111b和第二出料口111c。其中，第一出料口111b连接至对应的分物料管道1122，第二出料口111c连接至颗粒状或粉状产品生产线。取样器111内设置有横向管道115，且横向管道115的直径小于进料口111a的直径。活塞116在横向管道115中左右移动对落入横向管道中的颗粒状或粉状产品进行刮取。颗粒状或粉状产品从进料口111a进入取样器111，一部分通过活塞116刮入第一出料口111b后进入分物料管道1122，另一部分未被刮取的颗粒状或粉状产品通过第二出料口111c落回生产线。每个取样器111末端设置有对应的取样阀门114(如所示出的设置于最左侧的取样器111末端第一取样阀门1141至设置于最右侧的取样器111末端第九取样阀门1149)。取样阀门114与控制子系统5电相连，通过控制子系统5进行启停控制。系统工作时，可以根据需要打开任意一个或多个取样阀门114。例如，开启第一取样阀门1141，关闭第二取样阀门1142至第九取样阀门1149；开启第二取样阀门1142和第三取样阀门1143，关闭第一取样阀门1141和第四取样阀门1144至第九取样阀门1149。通过并联设置的多个取样器111、取样阀门114和分物料管道1122，可以实现单点或多点实时取样。As shown in Figures 2 and 4, each sampler 111 includes an inlet 111a, a first outlet 111b and a second outlet 111c. Among them, the first discharge port 111b is connected to the corresponding material distribution pipe 1122, and the second discharge port 111c is connected to the granular or powdery product production line. A transverse pipe 115 is provided in the sampler 111, and the diameter of the transverse pipe 115 is smaller than the diameter of the feed port 111a. The piston 116 moves left and right in the transverse pipe 115 to scrape the granular or powdery products falling into the transverse pipe. The granular or powdery product enters the sampler 111 from the feed port 111a. A part of it is scraped into the first outlet 111b through the piston 116 and then enters the material distribution pipe 1122. The other part of the granular or powdery product that has not been scraped passes through the third outlet. The second discharge port 111c falls back to the production line. Each sampler 111 is provided with a corresponding sampling valve 114 at the end (as shown, the first sampling valve 1141 is provided at the end of the leftmost sampler 111 to the ninth sampling valve 1149 is provided at the end of the rightmost sampler 111 ). The sampling valve 114 is electrically connected to the control subsystem 5, and is controlled on and off through the control subsystem 5. When the system is working, any one or more sampling valves 114 can be opened as needed. For example, open the first sampling valve 1141, close the second sampling valve 1142 to the ninth sampling valve 1149; open the second sampling valve 1142 and the third sampling valve 1143, close the first sampling valve 1141 and the fourth sampling valve 1144 to the ninth Sampling valve 1149. Single-point or multi-point real-time sampling can be achieved through multiple samplers 111, sampling valves 114 and material distribution pipelines 1122 arranged in parallel.
根据所示的实施方式，一个分物料管道1122的进口端连接一个取样器111。根据一种实施变型，一个分物料管道1122的进口端也可以连接多个取样器111，本实用新型对此不作限制。此外，多个取样器111包括多个自动取样器111A和至少一个手动取样器111B。其中，手动取样器111B的进口端为开放结构，而自动取样器111A的进口端连接至生产线的出口端。例如，根据所示的实施方式，设置八个自动取样器和一个手动取样器。可以理解，自动取样器和手动取样器的数量根据实际需要确定，例如，可以设置多个手动取样器，本实用新型对此不作限制。采用自动取样器111A可以便于实现系统的自动化工作，且密封性较好。采用手动取样器111B可以便于操作人员执行随机测试。将自动取样器111A与手动取样器111B相结合使用，提高检测效率的同时增加了系统的灵活性。According to the embodiment shown, a sampler 111 is connected to the inlet end of a sub-material pipeline 1122 . According to an implementation variation, the inlet end of one material distribution pipeline 1122 can also be connected to multiple samplers 111, and the utility model does not limit this. Furthermore, the plurality of samplers 111 includes a plurality of automatic samplers 111A and at least one manual sampler 111B. Among them, the inlet end of the manual sampler 111B has an open structure, and the inlet end of the automatic sampler 111A is connected to the outlet end of the production line. For example, according to the embodiment shown, eight automatic samplers and one manual sampler are provided. It can be understood that the number of automatic samplers and manual samplers is determined according to actual needs. For example, multiple manual samplers can be provided, and the present invention does not limit this. The automatic sampler 111A can facilitate the automation of the system and has better sealing. The manual sampler 111B can be used to facilitate the operator to perform random tests. Combining the automatic sampler 111A with the manual sampler 111B improves the detection efficiency and increases the flexibility of the system.
