[0001] The utility model relates to the technical field of boiler spare parts, in particular to a direct-blowing boiler coal powder sampler. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy.

[0003] At present, some existing samplers generally only need to sample coal powder when performing sampling work. However, there may still be unburned coal blocks inside the boiler after combustion is completed, and these unburned coal blocks may affect the sampling results. In addition, some existing samplers generally fix the sampling tube by friction through a clamping block when working. However, although this method can fix the coal blocks inside the tube, it may not be firmly fixed, which may affect the fixing effect. Therefore, there is an urgent need for a direct-blowing boiler coal powder sampler to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a direct-blowing boiler coal powder sampler to solve the problem of some existing samplers proposed in the above background technology, which may cause unburned coal blocks to be sampled together during sampling, which may further affect the sampling results. In addition, the storage tube of some existing samplers is generally fixed by a snap-fit ​​method. Although this method can effectively and quickly replace the storage tube, it may have the problem of unreliable fixation.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A direct-blowing boiler coal powder sampler includes a sampler body, the sampler body includes a sampling cylinder, the outer surface of the sampling cylinder is connected to a guide assembly, the interior of the sampling cylinder is connected to a first sealing block, the outer surface of the bottom end of the sampling cylinder is connected to a storage cylinder, and the outer surface of the storage cylinder is connected to a locking assembly.

[0007] Preferably, the locking assembly includes a threaded ring and a threaded member, the outer surface of the storage cylinder is connected to the threaded member, and the outer surface of the threaded member is sleeved with the threaded ring.

[0008] Preferably, the guide assembly includes a first stop block, a first guide block, a first filter screen, a torsion spring, a first clamping block and a first connecting ring. The outer surface of the sampling cylinder is connected to the first connecting ring, the inner wall of the first connecting ring is connected to the first clamping block, one side surface of the first clamping block is connected to the torsion spring, the inner wall of the first clamping block abuts against the first filter screen, the inner wall of the first filter screen is connected to the first stop block, and the inner wall of the sampling cylinder is connected to the first guide block.

[0009] Preferably, the inner wall of the sampling tube is provided with two groups of notches, and the internal shape and size of the notches are adapted to the shape and size of the outer surface of the first stop.

[0010] Preferably, a thread groove is formed on the inner wall of the threaded ring, and the internal shape and size of the thread groove are adapted to the shape and size of the outer surface of the threaded member.

[0011] Preferably, three groups of threaded members are provided, and the three groups of threaded members are evenly connected to the outer surface of the top end of the storage cylinder at equal distances.

[0012] Preferably, four groups of the first guide blocks are provided, and the four groups of the first guide blocks are evenly connected to the inner wall of the sampling cylinder at equal distances.

[0013] Preferably, one end of the torsion spring is connected to the outer surface of the first connecting ring, and the other end of the torsion spring is connected to the inner wall of the first clamping block.

[0014] Preferably, three groups of the first clamping blocks are provided, and the three groups of the first clamping blocks are evenly connected to the inner wall of the first connecting ring at equal distances.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the direct-blowing boiler coal powder sampler can effectively fix the storage cylinder while ensuring the fixing effect by setting a locking component, and the device can effectively and conveniently guide the coal powder for filtering by setting a guiding component.

[0016] 1. The device is provided with a guide assembly. When a worker operates the device before starting work, he can first open the first clamping block, then place the first filter screen on the inner wall of the first connecting ring, and loosen the first clamping block, so that the first clamping block rebounds due to the elastic force of the torsion spring, so that the first filter screen can begin to initially filter the coal powder. The first sealing block can be manually pressed to one side of the first filter screen, and then the sampling cylinder and the sampling port of the boiler can be manually abutted. Then, the first sealing block can be manually pulled outward to form a negative pressure inside the sampling cylinder, so that the coal powder inside the boiler is discharged, and then the coal powder can be easily entered into the sampling cylinder through the perforations on the surface of the first filter screen. The guidance of the first guide block can orderly guide the turbulent flow of air and coal powder, and when the first sealing block reaches the maximum stroke, the coal powder inside the sampling cylinder will fall due to gravity, so that the coal powder can be easily dropped into the storage cylinder, so that the coal powder sample can be collected.

[0017] 2. The device is provided with a locking assembly. When the staff needs to replace the storage tube, they can first manually hold the threaded ring and gradually rotate the threaded ring along the outer surface of the threaded part, so that the threaded ring slides downward along the outer surface of the threaded part. Then, the threaded part will no longer fix the bottom end surface of the threaded ring, so that the storage tube can be easily removed from the bottom end outer surface of the sampling tube, thereby facilitating maintenance and replacement of the storage tube.
