Description

Technical Field

[0001] The utility model relates to the technical field of coal-saving combustion-aiding agent sampling equipment, in particular to a coal-saving combustion-aiding agent sampling device. Background Art

[0002] Coal-saving combustion aid, also known as coal-saving and pollution-reducing agent, is a highly efficient chemical additive. Its main function is to improve the combustion efficiency of coal, reduce coal consumption, reduce pollutant emissions, and extend the service life of boilers. It can be used in a wide range of fields such as various tonnage coal-fired boilers, industrial kilns and briquette boilers. The existing coal-saving combustion aids are mainly in the form of solid particles and liquids. Among them, the granular coal-saving combustion aids will be sampled and inspected before leaving the factory.

[0003] However, when the existing sampling device for coal-saving combustion aids is in use, it can only collect samples from one position on the pile at a time. When it is necessary to sample samples at different positions and depths in the pile, multiple samplings are required, and the steps are cumbersome, time-consuming and laborious. Therefore, we propose a sampling device for coal-saving combustion aids to solve this problem. Utility Model Content

[0004] The utility model is to solve the problem that the existing sampling device for coal-saving combustion-aiding agent can only collect samples at one position on the pile at a time when in use, and when it is necessary to sample samples at different positions and depths in the pile, multiple samplings are required, the steps are cumbersome, time-consuming and laborious, and a sampling device for coal-saving combustion-aiding agent is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A coal-saving combustion-aiding agent sampling device, comprising:

[0007] A sampling cylinder, wherein a plurality of feed ports are provided on the sampling cylinder, a control mechanism is arranged inside the sampling cylinder, the bottom end of the sampling cylinder is arranged in a conical shape, the control mechanism comprises a rotating shaft, a counterweight seat is fixedly arranged on the bottom of the sampling cylinder, the rotating shaft is rotatably connected to the counterweight seat, a plurality of bearings are fixedly sleeved on the rotating shaft, a partition is fixedly arranged on the outer ring of the bearing, the partition is fixedly connected to the inner wall of the sampling cylinder, the cavity surrounded by the partition and the sampling cylinder is adapted to the feed port, a sleeve is fixedly sleeved on the rotating shaft, a connecting rod is fixedly arranged on the sleeve, an arc-shaped sealing plate is fixedly arranged on the connecting rod, the arc-shaped sealing plate is adapted to the corresponding feed port, a plurality of torsion springs are fixedly sleeved on the rotating shaft, and one end of the torsion spring is fixedly connected to the inner wall of the sampling cylinder.

[0008] Preferably, a first handle is fixedly provided on the top of the rotating shaft, and a second handle is fixedly provided on the top of the sampling cylinder.

[0009] In the utility model, the coal-saving combustion-aiding agent sampling device can control the sampling tube by holding the second handle, and further, the bottom end of the sampling tube is inserted into the material pile and inserted as deep as possible, and then the first handle is rotated to drive the rotating shaft to rotate, and the torsion spring is compressed at the same time, so as to drive the arc-shaped sealing plate to rotate. When the arc-shaped sealing plate is rotated away from the position of the feed port, the feed port is opened. At this time, the coal-saving combustion-aiding agent in the material pile will automatically enter the cavity due to its own pressure;

[0010] In the utility model, the coal-saving combustion-aiding agent sampling device, when enough samples are collected in the cavity, can reset the rotating shaft by reversing the first handle and cooperating with the force generated by the compression of the torsion spring, thereby driving the arc-shaped sealing plate to reset, so that the feed port can be blocked. At this time, the sampling is completed, and further, the sampling tube is taken out from the material pile to recover the sample;

[0011] The utility model is easy to use, and a plurality of partitions are provided to separate a plurality of cavities inside the sampling tube, and a control mechanism is cooperated to control the opening and closing of the feed port, so that samples at different positions can be taken out at one time and stored separately, which significantly improves the sampling efficiency.
