Description

Technical Field

[0001] This utility model relates to the field of power plant equipment technology, specifically to a power plant fuel sample preparation device. Background Technology

[0002] Power plants typically require fuel for operation, and coal is the primary raw material. Coal is a crucial energy source, and its composition significantly impacts fuel efficiency in power plants. Therefore, coal quality testing is paramount. The usual testing method involves sample preparation, creating a demand for power plant fuel sampling equipment. Power plant fuel sampling often involves crushing coal, extruding it into samples, and cutting it into uniform lengths before use.

[0003] The existing patent document with authorization announcement number CN221100212U discloses a novel power plant fuel sampling device, which comprises a sampling box, wherein the sampling box is a rectangular box-shaped structure, and L-shaped plate-shaped support frames are respectively installed on the bottom of both sides of the sampling box. The top and bottom near the left side are respectively connected to a hopper and a discharge pipe. In this technical solution, powdered coal is loaded into the sampling box from the hopper, and then a hydraulic device is activated to drive the telescopic rod to move in the sleeve, thereby driving the pressure plate to compact the coal into a specified shape in the sampling box. However, after using the dynamic pressure plate to compact the coal in the sampling box, the dynamic pressure plate needs to cooperate with the inner wall of the sampling box to complete the compaction of the coal. Thus, the compacted coal will inevitably stick to the inner wall of the sampling box, which makes it inconvenient to discharge the compacted coal. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a power plant fuel sample preparation device that solves the problem that the dynamic pressure plate needs to cooperate with the inner wall of the sample preparation box to complete the compaction of coal. As a result, the compacted coal will inevitably stick to the inner wall of the sample preparation box, which makes it difficult to discharge the compacted coal. By setting two pressing side plates, the thickness of the formed material can be controlled by controlling the distance between the two pressing side plates, thereby ensuring that it can be smoothly discharged from the discharge pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a power plant fuel sample preparation device, comprising a housing assembly, a sample preparation assembly, and a pressing assembly. The housing assembly includes a sample preparation box, the sample preparation assembly includes a positioning side plate and a limiting top plate, the pressing assembly includes a pressing side plate and a pressing slider, a feed hopper is connected to the top of the sample preparation box, a discharge pipe is connected to the lower end of the sample preparation box, and a mounting frame is bolted to the outer wall of the sample preparation box. The mounting frame is connected to the inner wall of the sample preparation box. The device is equipped with an anti-slip pad. One end of the positioning side plate is connected to a hydraulic cylinder. The end of the positioning side plate near the sample preparation box is connected to a positioning sleeve. The end of the positioning sleeve away from the positioning side plate is connected to the wall of the sample preparation box. A stabilizing slide rod is provided on the inner side of the positioning sleeve. A limit ring is connected to the inner wall of the positioning sleeve.

A limit slide groove is opened on the inner side of the limiting top plate away from the sample preparation box. A feed port is opened on the inner side of the limiting top plate.

[0006] The beneficial effects of this utility model are as follows: when the pressing side plates move closer to each other, the pressing side plates drive the pressing slider to slide during the movement, and the sliding of the pressing slider in the limiting groove ensures the stability of the pressing side plates during the movement. By setting two pressing side plates, the thickness of the molding material can be controlled by controlling the distance between the two pressing side plates, thereby ensuring that it can be smoothly discharged from the discharge pipe.

A support foot is connected to the end of the mounting frame away from the sample preparation box, and a valve is connected to the discharge pipe.

[0009] The beneficial effect of this improvement is that by setting up anti-slip pads, the friction between the pads and the sample preparation box is increased, thereby improving the stability of the connection between the reinforcing ribs and the sample preparation box.

[0014] As a further improvement to the above technical solution: the limiting rings are connected at equal intervals to the inner wall of the positioning sleeve, and the stabilizing slide rod is slidably connected to the limiting rings.

[0015] The beneficial effects of this improvement are as follows: when the pressure plate moves under the drive of the hydraulic cylinder, the pressure plate moves the connected stabilizing slide bar during the movement, and the movement of the stabilizing slide bar ensures the stability of the pressure plate during the movement.

[0016] In order for the hydraulic cylinder to drive the pressing side plate to compact the coal into a predetermined shape in the sample preparation box:

[0017] As a further improvement to the above technical solution: one end of the stabilizing slide rod penetrates through the side wall of the sample preparation box and extends to connect with the pressing side plate.

[0018] The beneficial effects of this improvement are as follows: When in use, powdered coal is added to the sample preparation box from the feed hopper, the hydraulic cylinder is started, the hydraulic cylinder drives the pressing side plate to compact the coal into a predetermined shape in the sample preparation box, and finally the valve of the discharge pipe is opened to release the coal sample from the discharge pipe.

[0020] As a further improvement to the above technical solution: a feed inlet is provided on the inner side of the top wall of the sample preparation box, and the bottom of the feed hopper is connected to the feed inlet.

[0021] The beneficial effects of this improvement are as follows: the opening of the limiting slide groove provides a channel for the sliding of the pressing slider, and the opening of the feed inlet allows the material added from the feed hopper to fall into the sample preparation box.

By setting two pressing side plates, the thickness of the molding material can be controlled by controlling the distance between the two pressing side plates, thereby ensuring that it can be smoothly discharged from the discharge pipe.
