Description

Technical Field

[0001] The utility model relates to the technical field of cement production, and more particularly to an energy-saving and environment-friendly cement production device. Background Art

[0002] Cement is a powdery, hydraulic, inorganic gelling material that forms a slurry when mixed with water. It can harden in air or water, and can firmly bind materials such as sand and stone together. The first step in cement production is to collect the raw materials. The collected raw materials need to be sent to a crusher for crushing to reduce their particle size. After crushing, they are discharged onto a conveyor belt and transported to the next processing step.

[0003] After cement ore is collected, it needs to be crushed in a crusher. Currently, large ore pieces are fed into the crusher for crushing, which breaks them into small pieces. This crushing process and the discharge of the crushed pieces onto the conveyor belt generate a large amount of dust, which can affect the work area and human health, and is detrimental to energy conservation and environmental protection. In light of this, we propose an energy-saving and environmentally friendly cement production device. Utility Model Content

[0016] 3. The utility model also designs a closing plate structure. When a large amount of dust occurs locally when the crusher is unloading, the closing plate can be turned to close the horn dust suction port that is not within the dust suction range by rotating the adjusting rod, thereby increasing the negative pressure suction force of other horn dust suction ports and improving the effect of local dust suction.

[0017] 4. The utility model also designs a core-type rubber membrane structure. When the horn suction port is working, the core-type rubber membrane can be kept open under the action of suction. When the local horn suction port is closed, the core-type rubber membrane can be closed because the horn suction port does not generate suction. This can prevent dust passing through the suction pipe from falling into the non-working horn suction port and prevent dust from being discharged from the horn suction port.

DETAILED DESCRIPTION

[0026] like Figures 1 to 7 As shown, the utility model relates to an energy-saving and environmentally friendly cement production device, comprising a crushing mechanism 100 and a feeding mechanism 200 and a dust removal mechanism 300 arranged at the upper end and the side end of the crushing mechanism 100. The crushing mechanism 100 includes a base plate 101 and a crushing box 103. A support rod 102 is welded to the upper end of the base plate 101, and the crushing box 103 is welded to the end of the support rod 102. A symmetrically distributed crushing roller 104 is rotatably installed in the crushing box 103. A discharge pipe 110 is provided at the lower end of the crushing box 103. The discharge pipe 110 is arranged in an arc shape. A conveyor belt 111 installed on the ground is provided on one side of the base plate 101 below the discharge pipe 110.

[0027] The feeding mechanism 200 includes a feeding pipe 201, which is installed at the upper end of the crushing box 103 and is arranged in an arc shape. A first baffle plate 202 and a second baffle plate 203 are rotatably installed in the feeding pipe 201. The second baffle plate 203 is located on one side of the first baffle plate 202. The lower ends of the first baffle plate 202 and the second baffle plate 203 are in contact with the inner wall of the bottom end of the feeding pipe 201.

[0028] The dust removal mechanism 300 includes a dust collecting box 301 and a dust removal fan 302 disposed at the upper end of the dust collecting box 301. The dust collecting box 301 is mounted at the rear end of the crushing box 103. A cleaning port is provided at the side of the dust collecting box 301, and a box door 303 is installed within the cleaning port. By designing a dust collection structure and a dust blocking structure, the present utility model can prevent dust generated during the crushing of cement raw material ore from surging out of the feed pipe 201 and generating dust. At the same time, it can also remove the large amount of dust generated when the ore is discharged onto the conveyor belt 111, effectively preventing dust and promoting energy conservation and environmental protection.

[0029] Specifically, a communication port is provided between the dust collecting box 301 and the air inlet of the dust removal fan 302, and a dust filter is provided in the communication port. The dust filter can prevent the dust in the dust collecting box 301 from being discharged when the dust removal fan 302 is working.

[0030] Furthermore, a dust collection pipe 304 is installed at the front end of the dust collection box 301, and a trumpet dust collection port 305 connected to the trumpet dust collection pipe 304 is threadedly installed at the lower end of the dust collection pipe 304. The trumpet dust collection port 305 is provided to collect dust generated by dust collection.

[0031] It is worth noting that the dust collection tube 304 includes a connecting portion 3041, a horizontal portion 3042, and an angled portion 3043. The connecting portion 3041 is L-shaped and communicates with the dust collection box 301. The angled portion 3043 is bent at the end of the horizontal portion 3042, with the angled portion 3043 bending upward. The angled portion 3043 and the horizontal portion 3042 are both composed of a plurality of pipes bent in a V-shape. The upward bending of the angled portion 3043 relative to the horizontal portion 3042 can accommodate the upward tilt angle of the conveyor belt 111 of the conveying equipment. At the same time, the angled portion 3043 and the horizontal portion 3042, composed of a plurality of V-shaped pipes, can effectively increase the dust collection range of the dust collection tube 304, thereby improving the dust removal effect.

[0032] It is worth noting that an adjusting rod 3052 is rotatably provided in the speaker dust suction port 305, a limiting plate is provided at the front end of the adjusting rod 3052, a closing plate 3051 is provided on the adjusting rod 3052, and the closing plate 3051 is located in the speaker dust suction port 305, and the end of the adjusting rod 3052 extends out of the speaker dust suction port 305 and is threadedly installed with a nut, and an anti-return mechanism 306 is threadedly installed in the speaker dust suction port 305, and the anti-return mechanism 306 includes a threaded mounting ring 3061, and a mounting rod 3062 is arranged in an array at the upper end of the mounting ring 3061, and a core rubber membrane 3063 is provided between the upper end of the mounting ring 3061 and the mounting rod 3062. When a large amount of dust occurs locally when the crusher is unloading, the closing plate 3051 can be turned to close the speaker dust suction port 305 that is not within the dust suction range by adjusting the adjustment rod 3052. After adjustment, the nut is tightened to fix the position of the closing plate 3051, which can increase the negative pressure suction force of other speaker dust suction ports 305 and improve the effect of local dust suction. When the speaker dust suction port 305 is working, the core rubber membrane 3063 can be kept open under the action of suction. When the local speaker dust suction port 305 is closed, the core rubber membrane 3063 can be closed because the speaker dust suction port 305 is closed and no suction is generated, which can prevent the dust passing through the dust suction pipe 304 from falling into the non-working speaker dust suction port 305, and prevent the dust from being discharged from the speaker dust suction port 305.

[0033] It is worth mentioning that a motor 108 is installed at the front end of the crushing box 103, and a driving pulley 109 is installed at the end of the output shaft of the motor 108. A first gear 105 is installed on the rotating shaft of the crushing roller 104 extending out of the crushing box 103. A second gear 106 and a driven pulley 107 are installed on the rotating shaft of the crushing roller 104 extending out of the crushing box 103 on the right side. The second gear 106 is meshed with the first gear 105, and a transmission belt is provided between the driven pulley 107 and the driving pulley 109. When the motor 108 is working, the driving pulley 109 can be rotated. Under the action of the transmission belt, the driving pulley 109 can be rotated, thereby rotating the second gear 106. The second gear 106 can drive the first gear 105 to rotate, so that the two crushing rollers 104 rotate synchronously relative to each other to crush the ore.

[0034] Working principle: This embodiment provides an energy-saving and environmentally friendly cement production device. When in use, ore is added to the feed pipe 201, and the ore can slide in the arc-shaped feed pipe 201 into the crushing box 103. When the ore slides and falls, the first baffle plate 202 and the second baffle plate 203 can be opened under the push of the ore. After the ore enters, the first baffle plate 202 and the second baffle plate 203 rotate to automatically close the feed pipe 201. The motor 108 can be used to rotate the two crushing rollers 104 to crush the ore. The dust generated during the crushing process can be prevented from gushing out of the feed pipe 201 by the action of the baffle plate. The crushed ore can be discharged from the discharge pipe 110 to the conveyor belt 111 of the cement conveying equipment, and is sucked by the dust removal fan 302, so that the dust suction pipe 304 generates suction to absorb the generated dust. The inhaled dust can enter the dust collecting box 301, and the dust suction The angle portion 3043 of the tube 304 is bent upward to adapt to the obliquely arranged conveyor belt 111, and can absorb the dust generated by the crushed stones falling to the starting position of the conveyor belt 111, thereby preventing the generation of a large amount of dust to pollute the working area. When a large amount of dust occurs locally when the crusher is unloading, the closing plate 3051 can be rotated to close the trumpet dust suction port 305 that is not within the dust suction range, thereby increasing the negative pressure suction force of other trumpet dust suction ports 305. When the trumpet dust suction port 305 is working, the core rubber membrane 3063 can be kept open under the action of suction. When the local trumpet dust suction port 305 is closed, the core rubber membrane 3063 can be closed because the trumpet dust suction port 305 is closed and no suction is generated, thereby preventing the dust passing through the dust suction pipe 304 from falling into the non-working trumpet dust suction port 305, thereby preventing the dust from being discharged from the trumpet dust suction port 305.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
