Description

Technical Field

[0001] The utility model belongs to the technical field of grain conveying dust removal, in particular to a grain conveying dust removal device. Background Art

[0002] A grain conveyor is a mobile belt conveyor primarily used for loading bulk grain into flat warehouses. The overall operation of a belt conveyor involves feeding grain into the conveyor's feed end and transporting it to the discharge section. However, this process generates a significant amount of dust, with the highest concentration occurring at the feed end where the bulk grain is unloaded. Grain dust is a non-conductive, combustible dust, and high dust levels can negatively impact grain storage. Dusty grain can easily compact, affecting its ability to respire and causing it to heat up, rot, and deteriorate.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Specific examples are given below.

[0027] See also Figure 1-Figure 5 The utility model provides a grain conveying dust removal device, comprising a dust removal bin 1, four supporting legs 2 are fixedly mounted on the bottom of the dust removal bin 1, and a feed port 3 is opened on the top of the dust removal bin 1;

[0028] It also includes a dust removal mechanism for removing dust from the grain;

[0029] The dust removal mechanism includes a fan 5, which is fixedly installed on one side of the dust removal bin 1. One side of the fan 5 is fixedly connected to an air inlet pipe 51, one end of the air inlet pipe 51 is fixedly connected to an air dryer 52, one side of the air dryer 52 is fixedly connected to an air outlet pipe 53, one end of the air outlet pipe 53 is fixedly connected to a dust removal box 54, a plurality of 62 are fixedly installed in the inner cavity of the 54, a sewage tank 542 is fixedly connected to the bottom of the dust removal box 54, the dust removal box 54 passes through the inner cavity of the dust removal bin 1, and two conveyor belts 41 are rotatably installed in the inner cavity of the dust removal bin 1, and the two conveyor belts 41 are at different heights.

[0030] The collected grain is mixed with a lot of dust. When the grain is transported, a lot of dust will be precipitated, so the dust in the grain needs to be cleaned.

[0031] When the present invention is in use, first, the grain is poured into the dust removal bin 1 from the feed port 3, and then the grain first contacts the conveyor belt 41 at a higher position, and then falls onto the conveyor belt 41 at a lower position. In the process of the grain falling, the fan 5 blows air into the dust removal bin 1, and the wind will blow through the fallen grain. At this time, the dust mixed in the grain will be blown out and enter the dust removal box 54. When the dust enters the dust removal box 54, the water sprayed by the water spray head 62 will soak the dust, causing the dust to fall into the sewage tank 542, thereby completing the cleaning of the dust in the grain.

[0032] Further, such as Figure 2 As shown, four conveyor shafts 4 are rotatably installed in the inner cavity of the dust removal bin 1. The four conveyor shafts 4 are divided into two groups, two by two. The heights of the two groups of conveyor shafts 4 are different. The two conveyor belts 41 are respectively wound around the outer surfaces of the two conveyor shafts 4 in the same group.

[0033] One side of the two adjacent conveying shafts 4 is fixedly connected to a pulley 43, and the two pulleys 43 are connected via a belt 44. One side of the pulley 43 is fixedly connected to a first motor 45, and one side of the first motor 45 is fixedly connected to a connecting frame 46. The connecting frame 46 is fixedly installed on one side of the dust removal bin 1.

[0034] When the utility model is in use, the output shaft of the first motor 45 drives the pulley 43 to rotate, and the transmission is carried out through the belt 44, so that the two pulleys 43 rotate together. The two pulleys 43 cooperate with the transmission shaft 4 and the conveyor belt 41 so that the two conveyor belts 41 can convey the grain. In the process of the grain falling from the conveyor belt 41 at a higher position to the conveyor belt 41 at a lower position, the grain is in a suspended state, which is convenient for separating the grain from the dust in the grain.

[0035] Further, such as Figures 2 to 5 As shown, the air dryer 52 is fixedly mounted on the top of the dust removal bin 1, the inner cavity of the dust removal bin 1 is fixedly mounted with a first baffle 11, the first baffle 11 is located on one side of the conveyor belt 41, the inner cavity of the dust removal bin 1 is fixedly mounted with a first windshield 12 and a second windshield 13, the inner cavity of the dust removal bin 1 is fixedly mounted with a second baffle 14, the second baffle 14 is located on the other side of the conveyor belt 41;

[0036] A sewage outlet pipe 543 is provided at the bottom of the sewage tank 542, a groove 541 is provided at the top of the dust removal box 54, a vent 15 is provided on one side of the dust removal bin 1, and a number of partition rods 16 are evenly fixedly installed on the inner surface of the vent 15, a cleaning member 55 is slidably installed on the inner surface of the dust removal box 54, two slide grooves 551 are provided on one side of the cleaning member 55, and a slide rod 552 is slidably installed on the inner surface of the slide groove 551, and the slide rod 552 is fixedly installed in the inner cavity of the dust removal box 54, a threaded hole 553 is provided on one side of the cleaning member 55, and a reciprocating screw rod 545 is threadedly connected to the inner surface of the threaded hole 553, and one end of the reciprocating screw rod 545 is fixedly connected to the second motor 544, and the second motor 544 is fixedly installed on one side of the dust removal box 54, and one side of the cleaning member 55 is slidably installed between the number of partition rods 16.

[0037] When the present invention is in use, the wind blown by the fan 5 will enter the dust removal box 54 through the ventilation port 15. During this process, the wind blown by the fan 5 can blow the dust in the grain into the dust removal box 54. Since the weight of the grain is also light, some grain may be blown into the dust removal box 54. Therefore, the grain can be blocked in the dust removal bin 1 by a plurality of partition bars 16. At the same time, in order to prevent the grain from being stuck between two adjacent partition bars 16, the reciprocating screw rod 545 is rotated by the output shaft of the second motor 544. The threaded hole 553, the slide groove 551 and the slide bar 552 can enable the cleaning member 55 to clean the grain between the two adjacent partition bars 16, and at the same time avoid the problem that the dust in the grain cannot be completely cleaned due to poor ventilation.

[0038] The cooperation of the first baffle 11, the first wind shield 12, the second wind shield 13 and the second baffle 14 can not only prevent food from leaking from the gap between the conveyor belt 41 and the inner wall of the dust removal bin 1, but also limit the path of the wind blown out by the fan 5, further enhancing the dust removal mechanism's treatment effect on dust in the food. The wind coming out of the dust removal bin 1 is blown into the dust removal bin 1 again by the fan 5 through the outlet pipe 53 and the air inlet pipe 51, thereby realizing air circulation.

[0039] Further, such as Figure 4 As shown, a connecting pipe 61 is fixedly installed on the inner surface of the groove 541, several water spray heads 62 are fixedly installed on the bottom of the connecting pipe 61, a water pipe 63 is fixedly connected to the top of the connecting pipe 61, one end of the water pipe 63 is fixedly connected to a water pump 64, and the bottom of the water pump 64 is fixedly connected to a clean water tank 65, and the clean water tank 65 is fixedly installed on the top of the dust removal bin 1.

[0040] When the present invention is in use, the dust entering the dust removal box 54 will be soaked by the water sprayed from the water spray head 62, and the dust with water will fall into the sewage tank 542 and finally be discharged from the sewage pipe 543. The air moistened by the water spray head 62 enters the fan 5 through the air outlet pipe 53. In order to avoid the air entering the dust removal bin 1 being moist, the air is dried by the air dryer 52 before entering the fan 5, and the water in the water spray head 62 enters the water spray head 62 from the clean water tank 65 through the water pump 64 and the water pipe 63.

[0041] Working principle: When the present invention is in use, the grain is first put into the dust removal bin 1 through the feed port 3. The grain entering the dust removal bin 1 first falls onto the conveyor belt 41 located at a high place. Under the action of the output shaft of the first motor 45, it is driven by the belt 44 and the two pulleys 43. The rotation of the two pulleys 43 drives the two conveyor belts 41 to rotate respectively. The rotation of the two conveyor belts 41 can transport the grain. When the grain is transported between the two conveyor belts 41, the fan 5 blows air to the grain, and the dust in the grain is blown out through the vent 15 into the dust removal box 54. The blown grain is stuck between the two adjacent partition bars 16. The reciprocating screw rod 545 is rotated by the output shaft of the second motor 544 to cooperate with the threaded hole 553 to enable the cleaning part 55 to clean the grain between the two adjacent partition bars 16.

[0042] The dust blown into the dust removal box 54 is soaked by the water blown out by the water nozzle 62 and then falls into the sewage tank 542, while the air continues to flow and enters the air dryer 52 through the air outlet pipe 53. At this time, the air is relatively humid. The air is dried by the air dryer 52 and then passes through the fan 5 into the dust removal bin 1.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
