Description

Technical Field

[0001] This utility model relates to the field of coal quality testing technology, and specifically to a coal quality testing device. Background Technology

[0002] Coal is a widely used fuel, with a large consumption in the coal-fired power industry. Coal costs account for more than 70% of the operating costs of thermal power plants. Ash content, calorific value, volatile matter, heavy liquid content, and the content of elements such as C, H, and S in coal are the main indicators for coal testing and analysis. They are also the main indicators for coal quality acceptance and settlement and for guiding boiler combustion. During the use of coal, the washability of coal, that is, the degree of separation of different density components in coal, can be determined through sinking and flotation tests. This helps to assess the washing potential of coal and determine the optimal washing process.

[0003] In the process of conducting a coal buoyancy test, the coal sample is first placed in a net bottom bucket, then the coal mud adhering to the coal is washed off with water, and then the net bottom bucket is placed in a heavy liquid bucket for the buoyancy test. When the net bottom bucket is placed in the heavy liquid bucket, in order to ensure full contact between the coal and the heavy liquid, the tester needs to manually swing the net bottom bucket back and forth to rotate it during the test, which increases the labor intensity of the tester. To address this, a coal quality testing device is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the testers need to manually swing the bottom of the net bucket back and forth to rotate during the test, which increases the labor intensity of the testers. This invention provides a coal quality testing device.

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

[0006] A coal quality testing device, comprising:

[0007] A fixed base, wherein a support base is provided on the first plane of the fixed base, the support base being open on one side, and the first plane being the contact surface between the fixed base and the support base;

[0008] The testing mechanism, located inside the fixed base, is used to test the sinking and floating of coal blocks.

The filter component is located inside the cleaning component and is used to hold coal blocks. The control component is located inside the fixed base and controls the cleaning component and filter component to swing the coal blocks.

[0009] Furthermore, the cleaning component includes a heavy liquid storage tank, which is disposed inside the support base and rotates relative to the support base. A connecting block is provided on the side of the heavy liquid storage tank relative to the support base, and a connecting groove is opened on the side of the connecting block relative to the support base. A support tube is provided inside the heavy liquid storage tank, and multiple through holes are opened inside the support tube.

[0010] Furthermore, the filter element includes a fixed barrel, which is disposed inside the support tube. A sliding ring is slidably connected inside the fixed barrel, and a filter plate is disposed inside the sliding ring. Multiple guide grooves are opened on the outer side of the sliding ring, and guide strips are disposed inside the guide grooves and connected to the fixed barrel.

[0011] Furthermore, the control component includes a rotating disk, which is disposed inside the support base. A connecting rod is provided at the edge of the rotating disk, and a connecting plate is connected to the end of the connecting rod. The connecting plate is rotatably connected to the support base. A transmission shaft is provided on the outside of the connecting plate, and the transmission shaft is adapted to the connecting groove.

[0012] Furthermore, the end of the support tube is provided with multiple limiting grooves, each of which is provided with a limiting block, and the limiting block is connected to the fixed barrel. The fixed barrel is also provided with a fixing ring.

[0013] Furthermore, the sliding ring is hollow inside, and a gripping rod is provided on the outer side of the sliding ring.

[0028] like Figures 1 to 6As shown, a coal quality testing device includes: a fixed base 1, with a support base 101 on the first plane of the fixed base 1. The support base 101 is open on one side, and the first plane is the contact surface between the fixed base 1 and the support base 101; a testing mechanism, disposed inside the fixed base 1, for detecting the sinking and floating of coal blocks. The testing mechanism includes a cleaning component 2, a filter component 3, and a control component 4. The cleaning component 2 is disposed outside the support base 101 for storing heavy liquids, the filter component 3 is disposed inside the cleaning component 2 for holding coal blocks, and the control component 4 is disposed inside the fixed base 1 and controls the cleaning component 2 and the filter component 3 to conduct sinking and floating tests on the coal blocks. The block swings. Specifically, when a coal sinking and floating test is required, heavy liquid is first added into the cleaning component 2, and then the filter component 3 containing coal is placed inside the cleaning component 2, so that the control component 4 can drive the cleaning component 2 and the filter component 3 to swing. During the swinging process of the cleaning component 2 and the filter component 3, the coal sinking and floating test is achieved. The fixed base 1 and the support base 101 are connected by buckles or bolts, which facilitates the maintenance and replacement of the control component 4 during use. The support base 101 provides support for the cleaning component 2 during use, ensuring the stability of the cleaning component 2 during use.

[0029] like Figures 1 to 6 As shown, the cleaning component 2 includes a heavy liquid storage tank 201, which is disposed inside the support base 101 and rotates relative to the support base 101. A connecting block 205 is provided on the side of the heavy liquid storage tank 201 relative to the support base 101, and a connecting groove 206 is formed on the side of the connecting block 205 relative to the support base 101. A support tube 202 is provided inside the heavy liquid storage tank 201, and multiple through holes 204 are formed inside the support tube 202. Specifically, during the coal testing process, the heavy liquid required for the test is stored in the heavy liquid storage tank 201, allowing the heavy liquid to perform a sinking and floating test on the coal. During use, the support tube 202 provides support and limitation for the filter element 3, allowing the filter element 3 to move freely during the test. The heavy liquid storage tank 201 rotates synchronously. The heavy liquid storage tank 201 can be a cylindrical or quadrangular prism-shaped container for holding liquid. The through hole 204 inside the support tube 202 can guide the heavy liquid inside the heavy liquid storage tank 201 into the support tube 202, ensuring that the heavy liquid can fully contact the coal block. The support tube 202 and the heavy liquid storage tank 201 can be connected by a buckle or bolt, so that the appropriate size of the support tube 202 can be selected according to the filter element 3 of different sizes. During use, the heavy liquid storage tank 201 is connected to the control element 4 through the connecting block 205, so that the control element 4 can drive the heavy liquid storage tank 201. The shape of the connecting groove 206 can be hexagonal groove or triangular groove, etc.

[0030] like Figures 1 to 6As shown, the filter element 3 includes a fixed bucket 301, which is disposed inside the support tube 202. A sliding ring 304 is slidably connected inside the fixed bucket 301, and a filter plate 305 is disposed inside the sliding ring 304. Multiple guide grooves are opened on the outer side of the sliding ring 304, and guide strips 306 are disposed inside the guide grooves. The guide strips 306 are connected to the fixed bucket 301. Specifically, when coal needs to be tested, coal is first added into the fixed bucket 301, and then the fixed bucket 301 with added coal is placed inside the support tube 202, so that the heavy liquid can perform a sinking and floating test on the coal inside the fixed bucket 301. The density of the sliding ring 304 is less than that of the heavy liquid. The liquid allows the filter plate 305 to float upwards during coal testing. As the filter plate 305 floats, the coal inside the fixed bucket 301 floats upwards through the cooperation of the sliding ring 304 and the filter plate 305, facilitating rapid separation of coal and liquid during testing. The guide strip 306 can be square, T-shaped, or cylindrical, etc. During use, the guide strip 306 guides the movement direction of the sliding ring 304, ensuring the accuracy of the sliding ring 304's movement. The fixed ring 302 can limit the floating sliding ring 304 to prevent it from separating from the fixed bucket 301.

[0031] like Figures 1 to 6 As shown, the control component 4 includes a rotating disk 403, which is disposed inside the support base 101. A connecting rod 404 is provided at the edge of the rotating disk 403, and a connecting disk 405 is connected to the end of the connecting rod 404. The connecting disk 405 is rotatably connected to the support base 101. A drive shaft 406 is provided on the outer side of the connecting disk 405, and the drive shaft 406 is adapted to the connecting groove 206. Specifically, during the coal testing process, the connecting disk 405 is driven to swing by the cooperation of the rotating disk 403 and the connecting rod 404. During the swinging process of the connecting disk 405... The transmission shaft 406 drives the heavy liquid inside the heavy liquid storage tank 201 and the coal inside the fixed tank 301 to make full contact. The length of the connecting rod 404 is less than the radius of the rotating disk 403. The shape of the transmission shaft 406 can be hexagonal prism or triangular prism, etc. The matching of the transmission shaft 406 and the connecting groove 206 means that the transmission shaft 406 can be inserted into the connecting groove 206 during use, and the connecting block 205 and the connecting disk 405 can be connected through the cooperation of the transmission shaft 406 and the connecting groove 206, thereby ensuring stability in the transmission process.

[0032] like Figures 1 to 6As shown, the end of the support pipe 202 is provided with multiple limiting grooves 203, and each limiting groove 203 is provided with a limiting block 303. The limiting block 303 is connected to the fixed bucket 301. The fixed bucket 301 is also provided with a fixing ring 302. Specifically, the limiting groove 203 and the limiting block 303 connect the fixed bucket 301 and the support pipe 202, so that the fixed bucket 301 can rotate synchronously with the support pipe 202 during the test, ensuring that the coal and heavy liquid can make full contact. The limiting block 303 and the limiting groove 203 have the same shape, and the shape of the limiting groove 203 can be an arc-shaped groove or a square groove, etc.

[0033] like Figures 1 to 6 As shown, the sliding ring 304 is hollow inside, and a gripping rod is provided on the outside of the sliding ring 304. Specifically, during use, the fixed bucket 301 is controlled by the gripping rod. The hollow sliding ring 304 further increases the buoyancy of the sliding ring 304 during use, which facilitates the separation of coal blocks from heavy liquid during use.
