Description

Technical Field

[0001] This utility model relates to the field of powder sampler technology, and in particular to a powder sampler. Background Technology

[0002] A powder sampler is a tool used to collect powder samples and is widely used in industries such as cement, coal, power, and chemicals. Its main functions include multi-point sampling, automated operation, and sample volume adjustment. Different models of powder samplers have specific technical parameters, such as diameter, length, and number of sampling points, to adapt to the needs of different industrial scenarios. Some devices adopt linear motor technology to ensure simple structure and no dust leakage.

[0003] Traditional manual samplers may fail to collect representative samples due to uneven powder mixing, such as differences in particle size and density. Samplers with fixed depths or locations may miss critical areas. Furthermore, if not cleaned in time, some powder can adhere to the sampler surface, affecting the accuracy of subsequent sampling. To address these issues, we propose a powder sampler. Utility Model Content

[0004] The purpose of this invention is to provide a powder sampler to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A powder sampler includes a base plate, a placement platform is fixedly connected to the outer surface of the base plate, a sample body is fixedly installed on the outer surface of the placement platform, and a cylinder is fixedly connected to the inside of the sample body.

[0007] In a further embodiment, a telescopic rod is fixedly installed inside the cylinder, and a sampling head is fixedly installed at the top end of the telescopic rod.

[0008] In a further embodiment, a water tank is fixedly connected to the outer surface of the base plate, and a water pump is fixedly installed inside the water tank.

[0009] In a further embodiment, the input end of the water pump is fixedly connected to a suction pipe, and the output end of the water pump is fixedly connected to an outlet pipe.

[0010] In a further embodiment, an operation box is fixedly connected to the outer surface of the water tank, and an operation switch is fixedly connected inside the operation box.

[0011] In a further embodiment, two operating handles are fixedly connected to the outer surface of the sample body, and a sealing ring is fixedly connected to the outer surface of the sample body.

[0012] In a further embodiment, a connecting hose is fixedly installed at the outlet of the water pipe, and a connecting pipe is fixedly connected to the outer surface of the sample body, with the bottom end of the connecting pipe connected to the top end of the collection head.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device features a cylinder-driven telescopic rod that adjusts the insertion depth of the sampling head, avoiding deviations caused by fixed-position sampling. This ensures sample collection from different layers, such as the upper, middle, and lower parts of the container, improving the representativeness of mixed powders. Different sampling head shapes, such as spiral and porous types, are designed based on powder characteristics like particle size and flowability to reduce the impact of particle stratification or selective adsorption. The water tank, pump, and connecting hoses automatically flush the sampling head and pipes after sampling, preventing residual powder from contaminating the next batch of samples. Compared to manual cleaning, automated flushing is more thorough, reducing the risk of human error. The sampling and cleaning process is controlled with a single button on the control panel, minimizing manual intervention and improving efficiency. The water tank and sample can be separated for rapid deployment in different environments, such as cleanrooms and outdoors. The cylinder and pipes can be made of corrosion-resistant materials, suitable for acidic or alkaline powders or high-humidity environments, reducing the cost of repeated testing due to inconsistent manual sampling. The pump and telescopic rod are standardized components, easy to replace, and have a long service life. Attached Figure Description

The bottom end of the connecting pipe 12 is connected to the top end of the sampling head 6. The telescopic rod 5 acts as the actuator of the cylinder 4, driving the sampling head 6 to extend into the powder to complete the sampling. Its adjustability ensures the flexibility and representativeness of the sampling. The sampling head 6 directly contacts the powder and completes the sampling task. Its design, such as shape and material, affects the efficiency and accuracy of sampling and needs to be optimized according to the characteristics of the powder. The water tank 7 stores cleaning water to provide water for automatic rinsing after sampling, avoiding cross-contamination between different batches of samples. Pump 8 provides power to transport water from water tank 7 through the pipeline system to sampling head 6 and connecting pipe 12, realizing automated cleaning function. Suction pipe 9 connects water tank 7 and the input end of pump 8, ensuring pump 8 can continuously draw clean water. Outlet pipe 10 delivers the pressurized clean water from pump 8 to connecting hose 11, guiding and distributing the water flow. Connecting hose 11 serves as a flexible connection between outlet pipe 10 and connecting pipe 12, adapting to positional changes during equipment movement and ensuring unobstructed water flow. Connecting pipe 12 guides the clean water into the sample body 3, cleaning the sampling head 6 and the sample... The channel is rinsed to remove residual powder. The operating handle 13 provides a hand support point for the operator, making it easy to accurately control the sampler and improve the stability and convenience of sampling. The sealing ring 14 is installed at the key interface of the sample body 3 to prevent powder or liquid leakage and ensure the sealing and safety of the sampling process. The operating box 15 integrates control components such as the operating switch 16 to protect the internal circuit and provide a human-machine interface to simplify the operation process. The operating switch 16 serves as the control center of the equipment and is used to start or stop the execution of functions such as sampling and cleaning, realizing one-button operation.

[0023] The working principle of this utility model is as follows: First, the sample body 3 is taken out through the placement platform 2 on the base plate 1. Then, with the cooperation of the cylinder 4, the telescopic rod 5 and the operating handle 13, the collection head 6 makes accurate and precise collection. The water pump 8 in the water tank 7 uses the suction pipe 9 to draw water and the connecting hose 11 on the outlet pipe 10 to connect to the connecting pipe 12 to clean the inside of the sample body 3. The internal operation is sealed by the sealing ring 14 to prevent external powder from flowing in and affecting the collection results. The equipment is started by the operating switch 16 in the operating box 15.
