Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] Please see Figure 1-8 The present invention provides the following technical solution: an intelligent coal blending device, including a support frame 7, a metering device 5 at the upper end of the support frame 7, a feed hopper 3 at the upper end of the metering device 5, a crushing roller 1 inside the feed hopper 3, a feeding auger 4 on one side of the feed hopper 3, a storage box 6 at the bottom end of the feeding auger 4, a discharge pipe 8 connected to the bottom end of the metering device 5, a feeding dust suppression component 2 on one side of the feed hopper 3, a mixing box adjustment component 10 on one side of the support frame 7 corresponding to the discharge pipe 8, a conveyor belt 9 at the bottom end of the mixing box adjustment component 10, waste collection components 11 on both sides of the conveyor belt 9, and an angle adjustment component 12 at one end of the waste collection component 11.

[0037] Specifically, the feeding dust suppression assembly 2 includes a limiting groove 21, a perforated plate 22, a support spring 23, a support block 24, a sealing plate 25, a collection box 26, a dust suppression device 27, and a fixing bolt 28. The inside of the feeding hopper 3 is symmetrically provided with support blocks 24, and the upper end of the support blocks 24 is provided with a support spring 23. The upper end of the support spring 23 is provided with a perforated plate 22. The feeding hopper 3 is provided with a collection box 26 on one side. The dust suppression device 27 is provided on one side of the inside of the collection box 26. The fixing bolt 28 is provided on the other side of the inside of the collection box 26. The sealing plate 25 is provided on one side of the fixing bolt 28. A limiting groove 21 is opened at one end of the perforated plate 22 corresponding to the fixing bolt 28.

[0038] By adopting the above technical solution, the crushed raw material falls onto the upper end of the perforated plate 22, causing the support spring 23 to vibrate under force. The perforated plate 22 vibrates with the support spring 23 and is limited by the fixing bolt 28 to restrict the vibration stroke and improve the stability of the equipment. Unfilterable raw material accumulates on one side of the blocking plate 25. When it is necessary to recycle the raw material, the fixing bolt 28 is loosened to remove the blocking plate 25 so that it no longer blocks the opening of the feed hopper 3. At this time, the screened raw material falls into the collection box 26 for recycling, reducing production costs and improving the use effect of the equipment.

[0039] Specifically, the dust suppression device 27 includes an air suction pipe 271, a grid plate 272, a fiber filter 273, positioning bolts 274, an air suction fan 275, and a sealing cover 276.

The side of the air suction fan 275 is provided with a fiber filter 273. The surface of the collection box 26 is provided with positioning bolts 274 corresponding to the fiber filter 273.

[0040] By adopting the above technical solution, the raw material is crushed by the crushing roller 1. At this time, the suction fan 275 can be turned on to perform suction. The airflow draws the dust generated during the crushing of the raw material into the collection box 26 through the suction pipe 271 for collection. The inside of the suction pipe 271 is equipped with a grid plate 272 to block the raw material and prevent waste. The inside of the collection box 26 is equipped with a fiber filter 273 to protect the suction fan 275, prevent dust from damaging the equipment, and prevent the sucked-in dust from being blown out, thereby improving the dust treatment effect.

[0041] In this embodiment, the raw material is crushed by the crushing roller 1. At this time, the suction fan 275 can be turned on to perform suction. The airflow draws the dust generated during the crushing of the raw material into the collection box 26 through the suction pipe 271 for collection. The inside of the suction pipe 271 is equipped with a grid plate 272 to block the raw material and prevent waste. The inside of the collection box 26 is equipped with a fiber filter 273 to protect the suction fan 275, prevent dust from damaging the equipment, and prevent the sucked-in dust from being blown out, thus improving the dust treatment effect.

[0042] The crushed raw material falls onto the upper end of the perforated plate 22, causing the support spring 23 to vibrate under force. The perforated plate 22 vibrates with the support spring 23 and is limited by the fixing bolt 28 to restrict the vibration stroke and improve the stability of the equipment. Unfilterable raw material accumulates on one side of the blocking plate 25. When it is necessary to recycle the raw material, the fixing bolt 28 is loosened to remove the blocking plate 25 so that it no longer blocks the opening of the feed hopper 3. At this time, the screened raw material falls into the collection box 26 for recycling, reducing production costs and improving the use effect of the equipment.

The airflow sucks the dust generated during the crushing of the raw materials into the collection box 26 through the suction pipe 271. The inside of the suction pipe 271 is equipped with a grid plate 272 to block the raw materials and prevent waste. The inside of the collection box 26 is equipped with a fiber filter 273 to protect the suction fan 275, prevent dust from damaging the equipment, and prevent the sucked-in dust from being blown out, thus improving the dust treatment effect.

[0067] The crushed raw material falls onto the upper end of the perforated plate 22, causing the support spring 23 to vibrate under force. The perforated plate 22 vibrates with the support spring 23 and is limited by the fixing bolt 28 to restrict the vibration stroke and improve the stability of the equipment. Unfilterable raw material accumulates on one side of the blocking plate 25. When it is necessary to recycle the raw material, the fixing bolt 28 is loosened to remove the blocking plate 25 so that it no longer blocks the opening of the feed hopper 3. At this time, the screened raw material falls into the collection box 26 for recycling, reducing production costs and improving the use effect of the equipment.

[0068] The crushed raw materials fall from the metering device 5 into the discharge pipe 8 for feeding. At this time, the mixing box body 106 can be installed on one side of the support frame 7 to mix the raw materials. Press the U-shaped card block 104 to move it along the guide rod 105 and compress the limit spring 103. Then insert the plug block 101 into the plug slot inside the support frame 7. At this time, release the U-shaped card block 104 so that the limit spring 103 pushes it to reset. One end of the U-shaped card block 104 is inserted into the limit card slot, ensuring that the mixing box body 106 is easy and stable to install, improving the efficiency of equipment use, saving manpower, and reducing installation costs.

[0069] When the raw material is discharged from the discharge pipe 8, the damping shaft 1071 can be rotated at the upper end of the mixing box body 106 so that the dust baffle 1075 covers the upper end of the discharge pipe 8, and the side baffle 1074 can be rotated along the fixed shaft 1072 to block the dust, prevent the feeding and mixing of materials from causing dust pollution to the working environment, protect human health, and improve the environmental protection of the equipment. At the same time, the staff can observe the mixing situation inside the mixing box body 106 at any time through the observation window 1073 to ensure the effectiveness of the equipment.

[0070] The mixed materials fall onto the surface of the conveyor belt 9 for conveying. After the materials are discharged from one end of the conveyor belt 9, some of the dropped materials will enter the waste bin 119 for collection. The materials attached to the surface of the conveyor belt 9 can be cleaned by the cleaning brush 115 to clean the surface of the conveyor belt 9. At the same time, coal powder can be recovered to prevent coal powder from damaging the equipment and to improve the service life of the equipment. A positioning spring 117 is set at the bottom of the movable plate 118 to ensure that the cleaning brush 115 at the top of the movable plate 118 is in contact with the surface of the conveyor belt 9, ensuring the cleaning quality of coal powder and improving work efficiency.

[0071] When the waste in the waste bin 119 needs to be utilized, the pull rod 1124 moves the positioning rod 1125. At this time, the abutment spring 1123 is compressed and the positioning rod 1125 is pulled out from the inside of the T-shaped plate 114. Then, the waste bin 119 can be slid sideways to pull it out from the bottom of the mounting bracket 111, which ensures the convenience of positioning and disassembling the waste bin 119, saves manpower, and improves the efficiency of waste recycling.

[0072] When it is necessary to raise the operating angle of the conveyor belt 9 to transport materials, the electric push rod 125 is activated to push the damping block 126 to move along the inside of the guide frame 124. At this time, the fixing rod 123 inside the damping block 126 is subjected to force, which drives the mounting frame 111 to rotate along the pin on one side of the support leg. The fixing rod 123 moves along the inside of the damping block 126, thereby raising one end of the conveyor belt 9, ensuring the feeding effect and improving the applicability of the equipment.

[0073] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
