Description

Technical Field

[0001] This utility model relates to the field of coal testing technology, specifically to a high-efficiency coal combustion performance testing device. Background Technology

[0002] Coal is a solid, combustible mineral formed gradually from ancient plants buried underground and undergoing complex biochemical and physicochemical changes. Known as "black gold" and the "food of industry," coal has been one of the main energy sources used by humankind since the 18th century.

[0003] The known publication number CN221765370U proposes a high-efficiency coal combustion performance testing device. Its background technology addresses the problem that "existing coal combustion performance testing devices have simple structures and limited functions, lack convenient material feeding capabilities, and also lack good combustion air filtration capabilities and convenient filter element replacement structures." To address this, the proposed solution includes a device body comprising a testing box, a workbench inside the testing box, a hinged seat on the workbench with a threaded rod rotatably mounted on the inner side of the hinged seat, a motor at one end of the threaded rod, a moving block screwed onto the threaded rod, a moving plate fixed to the upper end of the moving block, and a placement platform mounted on the moving plate.

[0004] However, the following problems were found in the implementation of the relevant technology: although the provided technical solution achieved the effects of feeding, filtering and replacement, it was inconvenient to clean and collect the waste after combustion. It required manual cleaning of the coal ash and slag after combustion, which was cumbersome and time-consuming. This reduced the ease of use of the device and the efficiency of coal testing. Therefore, a high-efficiency coal combustion performance testing device is proposed. Utility Model Content

[0022] And a lead screw fixedly connected to the output end of the motor, wherein the lead screw and the placement plate are threadedly connected.

[0023] Optionally, a blower is fixedly installed on the top of the testing box, and a filter box is fixedly installed on one side of the top of the testing box. The output end of the blower is connected to the filter box through a pipe. The filter box contains a primary filter and an activated carbon filter that are detachably installed from left to right.

As the movable seat rotates, the moving frame moves the cleaning plate, which scrapes off the waste from the surface of the placement plate, preventing waste residue. Thus, the waste from coal combustion is cleaned and collected without manual operation, avoiding burns and effectively improving ease of use and efficiency of coal detection.

[0036] When combustion gases are emitted, the gases are filtered through a primary filter screen. At the same time, an electric push rod drives a cleaning brush to move up and down to clean the primary filter screen. Then, the pump body pumps water into the flushing coil to flush the primary filter screen and cool the combustion gases. The gas can also be cooled a second time when it comes into contact with the flushing coil. Afterward, the collected impurities and water are collected in the collection box, which can prevent the high-temperature gas from damaging the filter elements and improve the filtration effect and service life of the filter elements.

[0050] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0051] Example 1, please refer to Figure 1 - Figure 5 The technical solution of this utility model is as follows: a high-efficiency coal combustion performance testing device, comprising: a testing box 1 and a collection drawer 2 slidably connected to its bottom, wherein the testing box 1 is equipped with a box door;

[0052] Rotating rod 3 is rotatably connected to the inside of the detection box 1, and the detection box 1 is equipped with a power mechanism 4 for driving the rotating rod 3;

[0053] Movable seat 5 is fixedly installed on the surface of rotating rod 3;

[0054] Placement plate 6 is located inside the movable seat 5;

[0055] The movable frame 7 is slidably connected to both sides of the movable base 5;

[0056] Cleaning plate 8 is fixedly installed on the inner top wall of the movable frame 7;

[0057] Ignition device 9 is fixedly installed on both sides of the test box 1;

[0058] Flamethrower 91 is fixedly installed on both sides of the inner side of the test box 1 and connected to the igniter 9.

[0059] The power mechanism 4 includes:

[0060] A worm gear 41 is fixedly connected to one end of the rotating rod 3, and one end of the rotating rod 3 extends out of the interior of the detection box 1;

[0061] Motor 42 is fixedly installed on one side of the detection box 1;

[0062] And a worm 43 that is fixedly connected to the output end of motor 42 and meshes with worm gear 41.

[0063] The technical solution provided in this embodiment is as follows: In use, coal is placed on the placement plate 6 by opening the box door, then the box door is closed, and the coal is burned using the igniter 9 and the flame gun 91. At this time, the combustion performance can be tested through the test box 1. After the combustion test is completed, the worm gear 43 is rotated by the motor 42, and the worm gear 43 drives the meshing worm wheel 41 to rotate, causing the rotating rod 3 to rotate 90 degrees. The rotating rod 3 then drives the movable seat 5 to rotate, thereby causing the placement plate 6 to rotate so that the combustion waste on its surface can be poured downwards into the collection drawer 2. The system collects waste materials from coal combustion. As the movable seat 5 rotates, the mobile frame 7 slides along with the movable seat 5 under its own weight, moving the cleaning plate 8. The cleaning plate 8 scrapes off and cleans the waste material on the surface of the placement plate 6, preventing waste residue. This achieves the effect of cleaning and collecting waste materials from coal combustion without the need for manual cleaning, avoiding burns and effectively improving ease of use and efficiency of coal detection. After cleaning, the movable seat 5 can be reset. To clean again, the movable seat 5 can be rotated in the opposite direction, allowing the mobile frame 7 to move again for cleaning.

[0064] Furthermore, the movable seat 5 is provided with a linear mechanism 10 for moving the placement plate 6.

[0065] Linear mechanism 10 includes:

[0066] The guide rails 101 are fixedly installed on both sides of the inner wall of the movable seat 5, and the placement plate 6 is slidably installed on the guide rails 101.

[0067] Motor 2 102 is fixedly installed on the inner bottom wall of movable seat 5;

[0068] And a lead screw 103 fixedly connected to the output end of motor 2 102, the lead screw 103 and the placement plate 6 are threadedly connected.

[0069] Specifically: When placing coal, motor 102 drives screw 103 to rotate, and screw 103 drives placement plate 6 to slide along guide rail 101, so that placement plate 6 slides out of movable seat 5 and out of detection box 1. Then, coal is placed on placement plate 6, and motor 102 drives screw 103 to reverse, so that placement plate 6 moves into detection box 1 and resets. This achieves the purpose of preventing personnel from putting their hands into the box to operate, and improves the safety of use.

[0070] Furthermore, a fan 11 is fixedly installed on the top of the test box 1, and a filter box 12 is fixedly installed on one side of the top of the test box 1. The output end of the fan 11 is connected to the filter box 12 through a pipe. The filter box 12 has a primary filter screen 13 and an activated carbon filter screen 14 that are detachably installed from left to right inside. A second fan 15 is fixedly installed on one side of the filter box 12.

[0071] Specifically: the gas produced by coal combustion can be transported to the filter box 12 by the first fan 11, and the gas in the filter box 12 can be extracted by the second fan 15. The gas is then filtered through the primary filter screen 13 and the activated carbon filter screen 14 in sequence before being discharged, preventing the gas from being discharged directly and causing pollution to the air environment.

[0072] Example 2, based on Example 1, in this example: the filter box 12 is provided with a flushing and cooling mechanism 16 for cleaning the primary filter screen 13 and cooling the combustion gas.

[0073] The flushing and cooling mechanism 16 includes:

[0074] A flushing coil 161 is fixedly installed inside the filter box 12 and located on one side of the primary filter screen 13. Multiple nozzles are installed on the surface of the flushing coil 161, and it is made of copper.

[0075] A pump body 162 is fixedly installed on one side of the filter box 12, and the output end of the pump body 162 is connected to the flushing coil 161 through a pipeline;

[0076] An electric push rod 163 is fixedly installed on the top of the filter box 12, and the output end of the electric push rod 163 moves through the filter box 12.

[0077] Cleaning brush 164 is fixedly connected to the output end of electric push rod 163;

[0078] A drain cover is fixedly installed at the bottom of the filter box 12;

[0079] And a collection box 165 fitted onto the surface of the sewage shell.

[0080] The technical solution provided in this embodiment is as follows: When emitting combustion gas, the gas is filtered through the primary filter screen 13. At the same time, the cleaning brush 164 is moved up and down by the electric push rod 163 to facilitate cleaning of the primary filter screen 13 and avoid clogging of the primary filter screen 13, which would affect the gas emission efficiency. Then, the pump body 162 is connected to an external water pipe to deliver external water to the flushing coil 161 and spray it onto the primary filter screen 13 for flushing. The sprayed water also cools the combustion gas. When the gas comes into contact with the flushing coil 161, it can be cooled a second time. Finally, the collected impurities and sprayed water are collected by the collection box 165. This can prevent the filter element from being damaged by high-temperature gas and improve the filtration effect and service life of the filter element.

[0081] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
