Description

Technical Field

[0001] This invention relates to the field of conveyor technology, specifically to a grain mash conveying device. Background Technology

[0002] In the grain processing industry, the conveying of grain mash is a crucial step. Traditional grain mash conveying devices typically employ a fixed conveyor casing and a screw conveyor shaft structure. Over long-term use, this structure often leads to severe wear on the inner wall of the conveyor casing due to the direct contact between the material and the casing. This not only affects conveying efficiency but also increases equipment maintenance costs.

[0003] To address this issue, some improved grain conveying devices have emerged on the market, which enhance wear resistance by adding a wear-resistant layer to the inner wall of the conveyor casing. However, these wear-resistant layers are usually integrally molded with the conveyor casing, and once they wear out severely, the entire conveyor casing needs to be replaced, which undoubtedly increases the difficulty and cost of equipment maintenance.

[0004] Therefore, this invention proposes a new grain mash conveying device. By installing a detachable wear-resistant inner tube inside the conveyor casing, the device not only avoids wear on the inner wall of the conveyor casing, but also facilitates the individual replacement of the worn wear-resistant inner tube, thereby greatly reducing the maintenance cost of the entire equipment.

[0032] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 13 This invention provides a technical solution: a grain mash conveying device, comprising a conveyor housing 1 and a conveyor housing 2. A flange 3 is fixed to one end of both the conveyor housing 1 and the conveyor housing 2. Multiple bolt holes 4 are formed on the surface of the flange 3. A screw conveyor shaft 9 is rotatably connected between the conveyor housing 1 and the conveyor housing 2. Both the conveyor housing 1 and the conveyor housing 2 are cylindrical. One end of the conveyor housing 1 has an opening, in which a bearing 10 is fixed. One end of the screw conveyor shaft 9 passes through the inner ring of the bearing 10 and is then connected to the power source of a servo motor unit 8. At the output end, the servo motor unit 8 is fixed at one end of the conveyor housing 1, and the other end of the screw conveyor shaft 9 is fitted with a bearing seat 11, which is fixed to the inner wall of the conveyor housing 2. The conveyor housing 1 and the conveyor housing 2 can be fixed together by bolts passing through the bolt holes 4 on the surfaces of the two sets of flanges 3. After the servo motor unit 8 is triggered, the servo motor unit 8 drives the screw conveyor shaft 9 to rotate. The screw conveyor shaft 9 transports the grain mash put into the conveyor housing 2 to the discharge port at the top of the conveyor housing 1 and puts it into the processing equipment, thus realizing the basic function of the screw conveyor.

[0034] A connecting plate 5 is provided between the two flanges 3. The connecting plate 5 has an annular plate structure. Sealing gaskets 33 are fixed on both sides of the connecting plate 5. The sealing gaskets 33 have an annular plate structure. The two sealing gaskets 33 are respectively clamped between the connecting plate 5 and the conveyor housing 1 and the conveyor housing 2. Insert handles 6 are fixed on both sides of the connecting plate 5. The insert handles 6 are inserted into the bolt holes 4. Each set of insert handles 6 has multiple insert handles. The insert handles 6 and bolt holes 4 correspond one-to-one. The insert handles 6 are convex cylindrical. A rubber clamp 7 is fixed on one end of the insert handle 6. The rubber clamp 7 has a spherical structure. The diameter of the rubber clamp 7 is larger than the diameter of the bolt hole 4. After the insert handle 6 is inserted into the bolt hole 4, the rubber clamp 7 blocks one side of the bolt hole 4. Wear-resistant inner tubes 16 are inserted into both sides of the connecting plate 5. Assembly grooves 15 are formed on both sides of the connecting plate 5, and the other end of the wear-resistant inner tube 16 is inserted into the assembly groove 15. An inner ring groove 14 is formed at the inner ring opening of the connecting plate 5, and multiple through holes 17 are formed on the two parallel sidewalls of the inner ring groove 14. A screw 18 is inserted into the through hole 17, and the length of the screw 18 is greater than the depth of the through hole 17. One end of the screw 18 is fixed to the other end of the wear-resistant inner tube 16, and a nut 19 is screwed onto the other end of the screw 18. A rubber cover 20 is fixed to the inner ring surface of the connecting plate 5, and a rubber retainer 21 is fixed to one end of the rubber cover 20. Ring 21 is a circular ring with a circular cross-section. The inner ring surface of the connecting plate 5 is provided with a groove 22. The groove 22 is an annular groove with a circular opening. After the rubber cover 20 is unfolded, the rubber ring 21 is inserted into the groove 22. At this time, the rubber cover 20 covers the inner ring groove 14. Two wear-resistant inner tubes 16 are respectively inserted into the conveyor housing 1 and the conveyor housing 2. One end of the wear-resistant inner tube 16 is fixed with a screw 24. The screw 24 passes through the conveyor housing 1 and the end of the screw 24 is screwed with a nut 25. Multiple through holes 23 are opened on the surface of the conveyor housing 2. The screw 24 and the through holes 23 correspond one-to-one. There are two sets of screws 24. The two sets of screws 24 are respectively fixed to one end of the two wear-resistant inner tubes 16.

[0035] To achieve the installation of detachable wear-resistant inner tubes 16 inside conveyor housing 1 and conveyor housing 2, thus preventing material wear on the inner walls of conveyor housing 1 and conveyor housing 2 and facilitating individual replacement of worn inner tubes 16, thereby reducing the overall maintenance cost of the equipment, conveyor housing 1 and conveyor housing 2 are no longer fixed with bolts. Instead, a connecting plate 5 is installed between conveyor housing 1 and conveyor housing 2. Conveyor housing 1 and conveyor housing 2 are respectively fitted onto the two wear-resistant inner tubes 16. After pushing conveyor housing 1 and conveyor housing 2 closer together, the two flanges 3 clamp the connecting plate 5. At this time, the insert 6 is inserted into the corresponding bolt hole 4, and the through hole 17 blocks the outside of the bolt hole 4, achieving the pre-limiting position of the two flanges 3. At this time, after the screw 24 passes through the corresponding through hole 23, the nut 25 is... The end of the wear-resistant inner tube 16 is screwed onto the end of the screw 24, so that one end of the wear-resistant inner tube 16 is fixed to the side plate of the conveyor housing 1, and the other end of the wear-resistant inner tube 16 is fixed to the side plate of the conveyor housing 2. It should be noted that the other end of the wear-resistant inner tube 16 is pre-fixed to the connecting plate 5. The specific operation is as follows: insert the other end of the wear-resistant inner tube 16 into the assembly groove 15. At this time, the screw 18 passes through the corresponding through hole 17. Pull the rubber retainer 21 out from the groove 22 and turn the rubber cover 20 inward to no longer cover the inner ring groove 14. Insert the nut 19 into the inner ring groove 14 and screw it onto the corresponding screw 18. Then turn the rubber cover 20 back and push the rubber retainer 21 into the groove 22. In this way, the rubber cover 20 covers the inner ring groove 14, and the other end of the wear-resistant inner tube 16 is fixed to the connecting plate 5 before the wear-resistant inner tube 16 is inserted into the conveyor housing 1. When the wear-resistant inner tube 16 is severely worn and needs to be replaced, first loosen the second nut 25, then pull the conveyor housing 1 and the second conveyor housing 2 from the two wear-resistant inner tubes 16, and then remove the wear-resistant inner tube 16 from the connecting plate 5.

[0036] Two wear-resistant inner tubes 16 have reserved openings 34 and 36 respectively on their surfaces. A discharge pipe 13 is fixed to the surface of the conveyor housing 1, corresponding to reserved opening 36. A feeding hopper 12 is fixed to the surface of the conveyor housing 2, corresponding to reserved opening 34. A rubber plug ring 35 is fixed to one end of the feeding hopper 12 that extends into the conveyor housing 2. The rubber plug ring 35 is an inverted frustum ring. After the wear-resistant inner tube 16 is inserted into the conveyor housing 2, the rubber plug ring 35 is inserted into... In the reserved port 34; an extension tube 37 is inserted into the top of the discharge tube 13. The extension tube 37 is a "T"-shaped round tube. The outer wall of the extension tube 37 is provided with external threads, and the inner ring surface of the discharge tube 13 is provided with internal threads. The internal threads and external threads are connected. After the extension tube 37 is lifted along the discharge tube 13, it extends into the reserved port 36. A sealing ring 38 is fixedly fitted on the top of the extension tube 37. The sealing ring 38 is clamped between the extension tube 37 and the reserved port 36. Multiple handle rods 39 are fixed at the bottom of the extension tube 37.

[0037] The reason for opening the reserved port 34 during use is that after the wear-resistant inner tube 16 is inserted into the conveyor housing 2, the material fed from the feeding hopper 12 can enter the wear-resistant inner tube 16 inside the conveyor housing 2 through the reserved port 34. The screw conveyor shaft 9 conveys the material to the discharge pipe 13. In order to ensure that the material in the wear-resistant inner tube 16 inside the conveyor housing 1 can be discharged through the discharge pipe 13, hold the handle rod 39 and turn the extension tube 37 to push it along the discharge pipe 13 to the reserved port 36 until one end of the extension tube 37 is inserted into the reserved port 36. At this time, the handle rod 39 is blocked at the bottom of the discharge pipe 13.

[0038] A heating tube 28 is embedded in the outer ring surface of the wear-resistant inner tube 16. A mounting groove 26 is formed on the outer ring surface of the other end of the wear-resistant inner tube 16. The mounting groove 26 is U-shaped, and the length of its long side is less than the length of the wear-resistant inner tube 16. Multiple mounting grooves 26 are arranged at equal intervals and of equal size along the outer ring surface of the wear-resistant inner tube 16. Each heating tube 28 corresponds to a mounting groove 26, and the heating tube 28 is fixed within the mounting groove 26. Two parallel mounting grooves 26... A protective mesh plate 27 is fixed between the distributed side walls. The heating pipe 28 is located between the protective mesh plate 27 and the mounting groove 26. A pressure relief hole 29 is provided on one side of the mounting groove 26. A through hole 30 is provided on the surface of the screw 24. The through hole 30 is connected to the pressure relief hole 29. A plurality of through holes 31 are provided on the surface of the inner ring groove 14. The through holes 31 are connected to the inner ring groove 14. A pressure relief valve pipe 32 is inserted and fixed on the outer ring surface of the connecting plate 5. One end of the pressure relief valve pipe 32 extends into the inner ring groove 14.

[0039] The reason for pre-installing the heating tube 28 on the outer wall of the wear-resistant inner tube 16 during use is to ensure that the wear-resistant inner tube 16 serves as a wear-resistant and replaceable inner tube, while the heating tube 28 heats the wear-resistant inner tube 16, allowing the wear-resistant inner tube 16 to heat and keep the raw materials transported inside. The air passage formed by the pressure relief hole 29 and the perforation 30 is used to relieve the high pressure generated by the heating tube 28. If the pressure relief efficiency is to be improved, the pressure relief valve pipe 32 is opened at the same time, and part of the air pressure enters the inner ring groove 14 through the perforation 31 and is discharged through the pressure relief valve pipe 32.

[0040] The operating procedure for this grain mash conveying device is as follows:

[0041] Initially secure conveyor housing 1 and conveyor housing 2 using bolts through flanges 3 and bolt holes 4, but do not tighten them at this stage to allow for later adjustments. Install connecting plate 5 between the two flanges 3, ensuring that gasket 33 is correctly clamped between connecting plate 5 and conveyor housing. Insert shank 6 into bolt holes 4 and secure it with rubber clips 7 to prevent shank 6 from falling off.

[0042] Insert one end of the wear-resistant inner tube 16 into the assembly slot 15 of the connecting plate 5, and secure it using screw 18 and nut 19. Install screw 24 at the other end of the wear-resistant inner tube 16, passing it through the perforation 23 of the conveyor housing, and secure it using nut 25. Ensure the wear-resistant inner tube 16 is correctly installed and not loose. Secure the feeding hopper 12 to the conveyor housing 2, and ensure the rubber plug ring 35 is correctly inserted into the reserved opening 34. Secure the discharge pipe 13 to the conveyor housing 1, and prepare the extension pipe 37.

[0043] Connect the power supply to the servo motor unit 8 and set the control switch. Connect the power supply to the heating tube 28 as needed and set the temperature controller. Turn on the switch of the servo motor unit 8 to drive the screw conveyor shaft 9 to start rotating. Feed the grain mash into the wear-resistant inner tube 16 inside the conveyor casing 2 through the feeding hopper 12. Turn on the power to the heating tube 28 to heat the wear-resistant inner tube 16 to maintain the temperature of the grain mash. Monitor the heating process to ensure that the temperature is controlled within the set range.

[0044] The screw conveyor shaft 9 transports the grain mash from conveyor housing 2 to conveyor housing 1. When the grain mash reaches the top of conveyor housing 1, it is discharged into the processing equipment through extension pipe 37 and discharge pipe 13. If the wear-resistant inner pipe 16 is found to be severely worn, it needs to be replaced.

[0045] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
