Description

Fly ash sampling device Technical Field The utility model belongs to the technical field of sampling devices, and particularly relates to a fly ash sampling device. Background Fly ash is one of important raw materials of cement concrete, and quality of the fly ash directly affects quality of the cement concrete, and in order to ensure quality of the fly ash, a sampling device is used for sampling before a fly ash transport vehicle is used for discharging. When the coal ash is sampled, sampling staff climbs to a reserved tank on the roof of the coal ash transport vehicle through a sampling platform or a ladder to sample, specifically, the sampling pipe is inserted into the coal ash until the sampling pipe is inserted to a preset depth, and then the sampling pipe is rotated, so that the coal ash at the depth is screwed into the sampling pipe through an inlet. Disclosure of utility model The utility model aims to solve the problems that the sampling representativeness is not strong and the sampling safety is low in the process of sampling the fly ash in the background technology. The utility model provides a fly ash sampling device, which comprises a vehicle body with the functions of loading, storing and unloading fly ash, and a discharging pipeline which is arranged on the vehicle body and is used for being connected with a warehouse-in pipeline so as to enable the fly ash stored in the vehicle body to enter a storage warehouse, wherein the connecting part of the warehouse-in pipeline and the discharging pipeline is provided with a sampling device which is used for carrying out multistage sampling on the fly ash in the discharging process of the vehicle body, and the sampling device comprises a sampling pipe which is arranged at the connecting part of the warehouse-in pipeline and the discharging pipeline and a valve which is arranged on the sampling pipe and is used for controlling the opening and closing states of the sampling pipe. Preferably, the device also comprises a controller, wherein the controller intermittently discharges the fly ash from the sampling pipe at the joint of the warehouse-in pipeline and the discharging pipeline by intermittently controlling the opening and closing of the valve so as to realize the sampling of the fly ash at different positions in the vehicle body. Preferably, the sample storage box capable of receiving the fly ash discharged from the output end of the sampling tube comprises a liner with an opening at the top and divided into a plurality of mutually independent storage spaces by a partition plate. Preferably, the sample storage box further comprises a shell, wherein the top opening of the shell is sealed through a detachable cover plate, a rotating assembly is installed inside the shell, the rotating assembly is used for driving an inner container placed inside the shell to rotate, a feed inlet capable of being connected with a sampling tube is formed in the cover plate, and the rotating assembly is controlled to operate by a controller. Preferably, the rotating component is a motor arranged at the bottom of the inner cavity of the shell and a tray positioned at the output end of the motor. Preferably, the bottom of each storage space of the liner is provided with a weighing component for weighing the weight of the fly ash. The multi-stage coal ash sampling device has the advantages that the sampling device is arranged at the joint of the warehouse-in pipeline and the unloading pipeline, so that the coal ash can be subjected to multi-stage sampling in the unloading process of the vehicle body, the comprehensiveness and the accuracy of coal ash sampling are ensured, more effective monitoring on the quality of the coal ash is facilitated, and meanwhile, the sampling safety of sampling personnel can be ensured.
