Description

Technical Field

[0001] The present invention relates to the technical field of conveyors, and particularly to a device for conveying fermented grains. Background Art

[0002] In the grain processing industry, the conveying of fermented grains is a crucial link. Traditional devices for conveying fermented grains usually adopt a structure of a fixed conveyor housing and a spiral feeding shaft. During long-term use, due to the direct contact between the material and the conveyor housing, severe wear of the inner wall of the conveyor housing often occurs, which not only affects the conveying efficiency but also increases the maintenance cost of the equipment.

[0003] To solve this problem, some improved devices for conveying fermented grains have emerged in the market. They improve the wear resistance by adding a wear-resistant layer to the inner wall of the conveyor housing. However, these wear-resistant layers are usually integrally formed with the conveyor housing. Once severely worn, the entire conveyor housing needs to be replaced, which undoubtedly increases the maintenance difficulty and cost of the equipment.

[0004] Therefore, the present invention proposes a new device for conveying fermented grains. By installing a detachable wear-resistant inner tube inside the conveyor housing, not only the wear of the inner wall of the conveyor housing is avoided, but also the worn wear-resistant inner tube can be replaced separately, thus greatly reducing the maintenance cost of the entire equipment.

[0035] In order to install a detachable wear-resistant inner pipe 16 inside the conveyor housing one 1 and the conveyor housing two 2, that is, to prevent the inner walls of the conveyor housing one 1 and the conveyor housing two 2 from being worn by materials, and to facilitate the separate replacement of the worn wear-resistant inner pipe 16, thereby reducing the maintenance cost of the entire equipment; at this time, the conveyor housing one 1 and the conveyor housing two 2 are no longer fixed with bolts, but a connection plate 5 is installed between the conveyor housing one 1 and the conveyor housing two 2. The conveyor housing one 1 and the conveyor housing two 2 are respectively sleeved on two wear-resistant inner pipes 16. After pushing the conveyor housing one 1 and the conveyor housing two 2 closer, two flange plates 3 clamp the connection plate 5. At this time, the insertion handle 6 is inserted into the corresponding bolt hole 4, and the through hole one 17 blocks the outside of the bolt hole 4 to realize the pre-limitation of the assembly of the two flange plates 3; and at this time, the screw two 24 passes through the corresponding through hole two 23, and then the nut two 25 is sleeved and screwed on the end of the screw two 24. In this way, one end of a wear-resistant inner pipe 16 is fixed on the side plate of the conveyor housing one 1, and one end of the other wear-resistant inner pipe 16 is fixed on the side plate of the conveyor housing two 2; it should be noted that the other end of the wear-resistant inner pipe 16 is pre-fixed on the connection plate 5. The specific operation is as follows: insert the other end of the wear-resistant inner pipe 16 into the assembly groove 15. At this time, the screw one 18 passes through the corresponding through hole one 17, pull out the rubber retaining ring 21 from the card slot 22, and turn the rubber cover 20 inward so as not to block the inner ring groove 14. After the nut one 19 extends into the inner ring groove 14, sleeve and screw it on the corresponding screw one 18. Then, after turning the rubber cover 20 back, push the rubber retaining ring 21 into the card slot 22. In this way, the rubber cover 20 covers the inner ring groove 14, and the other end of the wear-resistant inner pipe 16 is fixed on the connection plate 5 before the wear-resistant inner pipe 16 is inserted into the conveyor housing one 1. When the wear-resistant inner pipe 16 is severely worn and needs to be replaced, first loosen the nut two 25, then pull the conveyor housing one 1 and the conveyor housing two 2 away from the two wear-resistant inner pipes 16, and then remove the wear-resistant inner pipe 16 from the connection plate 5.

[0036] Respective surfaces of two wear-resistant inner pipes 16 are provided with a first reserved port 34 and a second reserved port 36.

One end of the feeding hopper 12 extending into the second conveyor housing 2 is fixed with a rubber plug ring 35. The rubber plug ring 35 is an inverted frustum ring. After the wear-resistant inner pipe 16 is inserted into the second conveyor housing 2, the rubber plug ring 35 is plugged into the first reserved port 34. A extension pipe 37 is plugged on the top of the discharge pipe 13. The extension pipe 37 is a "T"-shaped circular pipe. An external thread is provided on the outer wall of the extension pipe 37, and an internal thread is provided on the inner circumferential surface of the discharge pipe 13. The internal thread and the external thread are in mating connection. After the extension pipe 37 is lifted along the discharge pipe 13, it extends into the second reserved port 36. A sealing ring 38 is sleeved and fixed at the top end of the extension pipe 37. The sealing ring 38 is clamped between the extension pipe 37 and the second reserved port 36. A plurality of handle rods 39 are fixed to the bottom end of the extension pipe 37.

[0037] During use, the first reserved port 34 is provided so that after the wear-resistant inner pipe 16 is inserted into the second conveyor housing 2, materials fed from the feeding hopper 12 can enter the wear-resistant inner pipe 16 inside the second conveyor housing 2 through the first reserved port 34, and the spiral feeding shaft 9 conveys the materials towards the discharge pipe 13. To ensure that the materials in the wear-resistant inner pipe 16 inside the first conveyor housing 1 can be discharged through the discharge pipe 13, hold the handle rods 39 and twist the extension pipe 37 to push it along the discharge pipe 13 towards the second reserved port 36 until one end of the extension pipe 37 is inserted into the second reserved port 36. At this time, the handle rods 39 block the bottom end of the discharge pipe 13.

[0038] A heating pipe 28 is embedded on the outer circumferential surface of the wear-resistant inner pipe 16. An installation groove 26 is formed on the outer circumferential surface at the other end of the wear-resistant inner pipe 16. The installation groove 26 is a "U"-shaped groove.

One end of the pressure relief valve pipe 32 extends into the inner ring groove 14.

[0039] During use, the heating tube 28 is pre-installed on the outer wall of the wear-resistant inner tube 16 to meet the requirements that the wear-resistant inner tube 16 serves as a wear-resistant and replaceable inner tube, and at the same time, after the heating tube 28 works to heat the wear-resistant inner tube 16, the wear-resistant inner tube 16 heats and keeps warm the raw materials transported inside; the air duct formed by the pressure relief hole 29 and the perforation four 30 meets the requirement of relieving the high pressure generated by the heating tube 28 during operation. If it is necessary to improve the pressure relief efficiency, the pressure relief valve tube 32 is opened simultaneously, and part of the air pressure enters the inner ring groove 14 through the perforation five 31 and is discharged through the pressure relief valve tube 32.

[0040] The usage process of this grain and fermented grains conveying device is as follows:
