Description

Technical Field

[0001] This utility model relates to the field of coal mill technology, specifically to a coal mill slag discharge structure. Background Technology

[0002] A coal mill is a machine that crushes and grinds coal into pulverized coal. It mainly does so through three methods: crushing, impacting, and grinding. Since coal slag is generated during the operation of the coal mill, it needs to be discharged through a slag discharge structure to avoid accumulating inside the coal mill and affecting its use.

[0003] Currently, the slag discharge structure lacks a feeding anti-blocking mechanism. Usually, when coal slag enters the slag discharge structure through the feeding pipe, it is easy to cause blockage due to accumulation, affecting the stability of the slag discharge effect. Therefore, a coal mill slag discharge structure is proposed, which can increase the fluidity of coal slag by agitation while it enters, avoiding accumulation in the feeding pipe and blockage that affects the slag discharge effect, thereby improving the stability of slag discharge and the effectiveness of the device. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides a slag discharge structure for a coal mill, so as to avoid slag accumulation in the feed pipe, which would cause blockage and affect the slag discharge effect, thereby improving the stability of slag discharge and the effectiveness of the device.

[0009] By adopting the above technical solution, the elasticity can be used to assist in the separation of coal slag and dust, thereby improving the filtration and cleaning effect.

[0010] Specifically, the guide rod is fitted with annular air cushion strips on both sides of the slider. One end of the annular air cushion strip is connected to the slide rail by adhesive bonding, and the other end of the annular air cushion strip is connected to the slider by adhesive bonding.

[0011] By adopting the above technical solution, the position of the adjustment slider can be controlled by utilizing the deformation generated by inflation.

[0012] Specifically, the filter assembly includes a filter box, and the housing is connected to the filter box by bolts. A water tank is provided inside the filter box, and a guide pipe is connected to the top of the filter box by bolts. The feed end of the guide pipe is connected to the feed guiding assembly.

[0015] By adopting the above technical solution, negative pressure can be used to draw dust into the filter assembly during the slag discharge process.

[0016] Specifically, the feeding assembly includes a feeding cylinder, the bottom of which is connected to the housing. A feeding screw is installed inside the feeding cylinder via a bearing. A drive motor is bolted to the top of the feeding cylinder, and the drive motor is connected to the feeding screw via a drive shaft.

[0017] By adopting the above technical solution, the screw can be used to evenly feed coal slag into the slag discharge structure.

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] To prevent slag buildup in the feed pipe from causing blockages and affecting slag discharge, and to improve the stability of slag discharge and the overall performance of the equipment, such as... Figure 1-3As shown, the slag discharge structure of the coal mill of this utility model includes a shell 1, a feed pipe 3 and a material guiding component 4. The top of the shell 1 is provided with a feed component 2, and a feed pipe 3 is provided on one side of the feed end of the feed component 2. The top of the shell 1 is provided with a material guiding component 4 located at the bottom of the feed component 2, and a filter component 5 is provided on one side of the top of the shell 1 located at the feed component 2.

[0034] The inner surface of the feed pipe 3 is provided with a slide rail 301. A guide rod 302 is connected to the slide rail 301 by bolts. A slider 303 is sleeved around the guide rod 302. The sliders 303 are connected to each other by bolts with a slide rod 304.

[0035] In use, the sliding mechanism 301, slider 303 and slide bar 304 can improve the situation of coal slag accumulation and blockage in the feed pipe 3, increase the fluidity of coal slag, and the structure is simple. It is more stable and reliable in use and also helps to improve the slag discharge efficiency.

[0036] To improve the working environment of the slag discharge structure, for example, such as Figure 4 , Figure 5 As shown, the present invention also includes a material guiding assembly 4 comprising a material guiding groove 401, and the housing 1 being bolted to the material guiding groove 401. Both sides of the material guiding groove 401 are bolted to mounting seats 402. A material guiding plate 403 is rotatably connected between the mounting seats 402. Both sides of the material guiding plate 403 are bolted to a rotating shaft 404, and the material guiding plate 403 is rotatably connected to the mounting seats 402 via the two rotating shafts 404. A coil spring 405 is sleeved around the rotating shaft 404. One end of the coil spring 405 is welded to the rotating shaft 404, and the other end of the coil spring 405 is connected to the mounting seat 402 via a slot.

[0037] In use, the rotation of the mounting base 402 and the guide plate 403, as well as the elasticity of the coil spring 405, can be used to throw up the slag and dust for auxiliary separation, so that they can be extracted and filtered using negative pressure.

[0038] For example, such as Figure 2 As shown, the present invention also includes annular air cushion strips 305 on both sides of the guide rod 302 located on both sides of the slider 303. One end of the annular air cushion strip 305 is connected to the slide rail 301 by adhesive bonding, and the other end of the annular air cushion strip 305 is connected to the slider 303 by adhesive bonding.

[0039] When in use, the deformation caused by the inflation and deflation of the annular air cushion strip 305 can be used to control the position of the adjusting slider 303. The structure is simple, the cost is low, and the use is more flexible and reliable.

[0040] For example, such as Figure 6As shown, the present invention also includes the following: the filter assembly 5 includes a filter box 501, and the housing 1 is connected to the filter box 501 by bolts. A water tank 502 is provided inside the filter box 501. The top of the filter box 501 is connected to the guide pipe 503 by bolts, and the feed end of the guide pipe 503 is connected to the guide assembly 4.

[0041] When in use, the water tank 502 and the guide pipe 503 can be used to filter the dust entering the filter box 501, thereby improving the working environment of the slag discharge structure.

[0042] For example, such as Figure 6 As shown, the present invention also includes a filter box 501 with a top of a fan 504 connected by bolts, and the air inlet of the fan 504 is located inside the filter box 501. A filter element 505 corresponding to the fan 504 is provided on the top of the filter box 501.

[0043] When in use, the negative pressure generated by the exhaust fan 504 can draw the dust in the housing 1 into the filter assembly 5, and the filter element 505 can improve the dust filtration effect.

[0044] For example, such as Figure 7 As shown, the present invention also includes the following: the feeding assembly 2 includes a feeding cylinder 201, and the bottom of the feeding cylinder 201 is connected to the housing 1. A feeding screw 202 is installed inside the feeding cylinder 201 through a bearing. The top of the feeding cylinder 201 is connected to a drive motor 203 through bolts, and the drive motor 203 is connected to the feeding screw 202 through a drive shaft.

[0045] In use, the drive motor 203 can drive the feeding screw 202 to rotate, so that the coal slag can be evenly fed into the shell 1 for slag discharge.

[0046] For example, such as Figure 3 As shown, the present invention also includes a conveyor belt 6 provided at the bottom of the housing 1, the housing 1 including a slag discharge port 101, and the slag discharge port 101 being located at the bottom of one side of the conveyor belt 6.

[0047] When in use, the conveyor belt 6 can be used to drive the coal slag from the slag discharge port 101 to complete the slag discharge.

[0048] When this utility model is in use, the coal slag first enters the feed pipe 3 from the coal mill. An external air pump can be manually turned on to repeatedly charge and de-charge the annular air cushion strip 305. The deformation generated by the charging and de-charging pushes the slider 303 and the slide rod 304 to move back and forth. This increases the fluidity of the coal slag feed by sliding, making it less susceptible to blockage of the feed pipe 3 due to accumulation.

[0049] Next, the coal slag enters the feed cylinder 201. The drive motor 203 is manually turned on to drive the feeding screw 202 to rotate, and the coal slag is evenly fed into the guide trough 401. Under its own weight, it falls onto the guide plate 403 in sequence. Through the elastic force of the coil spring 405, the coal slag and the dust mixed in it are thrown upward, thus playing an auxiliary separation role. At the same time, the exhaust fan 504 is manually turned on. Using the negative pressure generated by the exhaust, the dust in the guide trough 401 is drawn into the filter box 501 through the guide pipe 503. The dust is then further treated by the water tank 502, which greatly improves the dust generated during the slag discharge process, reduces pollution to the working environment, and helps protect the health of the operators. Finally, the coal slag that falls on the conveyor belt 6 is conveyed and sent out from the slag discharge port 101 to complete the slag discharge process. The overall structure is simple and the use is more stable and reliable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
