Description

Technical Field

[0001] This utility model relates to the field of power transmission technology for ash dischargers in distillation furnaces, and more specifically, to a connection device for a single-unit drive system of a distillation furnace. Background Technology

[0002] In the shale processing process, electric locomotives transport the ore body to the raw ore workshop. After crushing and screening, shale blocks ranging from 12mm to 75mm in size are sent to the crude oil unit's storage bins. The shale in the storage bins is then fed into a retort furnace via a loading machine. Due to the continuous operation of the ash remover, the shale in the furnace continuously descends, simultaneously heated by gas from the generating section and circulating gas. Before reaching 105℃, the moisture in the shale evaporates. When the temperature rises to 150℃ to 180℃, the shale releases adsorbed gases. When the temperature exceeds 180℃, the organic matter in the shale decomposes, releasing gases such as water, carbon dioxide, and hydrogen sulfide, and forming bitumen and primary tar that can be extracted by organic solvents. In other words, when the shale is heated to 330℃, low-boiling-point volatile fractions begin to form, and a large amount of tar is released at temperatures between 350℃ and 550℃. The generated tar gas rises and is then discharged through an exhaust fan. Each distillation furnace has a single-drive system linked to the ash discharger, providing power for the continuous operation and ash discharge of the ash discharger. The coupling in the single-drive system is responsible for connecting the reducer and the reamer. However, the existing chain coupling has problems such as complex maintenance and upkeep, which leads to reduced production efficiency and reduced continuous operation time of the equipment. To address this, we propose a connection device for the single-drive system of the distillation furnace. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a connection device for a single-unit drive system of a dry distillation furnace.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A connecting device for a single-unit drive system of a distillation furnace includes a first half-coupling, a second half-coupling, and a cross slide. The first half-coupling has a first transmission groove at one end, and the second half-coupling has a second transmission groove at one end. The cross slide has a first transmission seat at one end, which is movably fitted into the inner cavity of the first transmission groove. The cross slide has a second transmission seat at the other end, which is movably fitted into the inner cavity of the second transmission groove. Both the first and second half-couplings are provided with two lubrication mechanisms.

[0006] As a preferred embodiment of this utility model, the lubrication mechanism includes powder storage tanks respectively opened inside the first half coupling and the second half coupling. The inner wall of each powder storage tank is provided with stepped threaded holes, and the inner cavity of each stepped threaded hole is threaded with an internal hexagon bolt. Powder outlet holes are respectively opened at both ends of the inner cavity of the powder storage tank.

[0007] As a preferred embodiment of this utility model, the first half-coupling and the second half-coupling are both provided with shaft connection holes in the middle, and the other end of the first half-coupling and the second half-coupling are provided with fixing thread holes on the side.

[0008] As a preferred embodiment of this utility model, a first outward inclined slope is provided on both sides of the inner cavity of the first transmission groove, and a first outward inclined angle is provided on both sides of the first transmission seat.

[0009] As a preferred embodiment of this utility model, the inner cavity of the second transmission groove is provided with a second outward inclined slope on both sides, and the second transmission seat is provided with a second outward inclined angle on both sides.

[0010] As a preferred embodiment of this utility model, the first half-coupling, the second half-coupling, and the cross slide are all made of high-strength wear-resistant materials.

[0011] The advantages of this utility model are:

[0012] (1) In this utility model, the reducer shaft and the reamer shaft are connected by the cooperation between the first half-coupling, the second half-coupling, and the cross slide. Furthermore, a certain degree of misalignment can occur between the first transmission groove and the first transmission seat, and between the second transmission groove and the second transmission seat, thereby providing angular compensation capability between the reducer shaft and the reamer shaft. This capability can accommodate large angular deviations between the two shafts, and the greater angular compensation capability can effectively reduce reamer wear, contributing to the continuous and stable operation of the equipment. It can increase the service life of the equipment, enhance load-bearing capacity, ensure smooth operation, reduce noise, and facilitate easy assembly, disassembly, and maintenance, making it highly practical.

[0013] (2) In this utility model, lead powder is pre-stored in the powder storage tank by using the powder storage tank, stepped threaded hole, powder outlet hole and internal hex bolt. During the rotation of the first half coupling and the second half coupling, the lead powder in the powder storage tank enters the first transmission groove and the second transmission groove from the powder outlet hole. The lead powder is used to lubricate the first transmission groove and the first transmission seat, the second transmission groove and the second transmission seat, and reduce the wear between the first transmission groove and the first transmission seat, the second transmission groove and the second transmission seat. This effectively reduces the wear between the first half coupling, the second half coupling and the cross slide, and extends the service life of the connection device of the single-machine drive system of the dry distillation furnace.

[0024] Example:

[0025] Please see Figure 1-5 A connecting device for a single-unit drive system of a distillation furnace includes a first half-coupling 1, a second half-coupling 2, and a cross slide 3. The first half-coupling 1 has a first transmission groove 4 at one end, and the second half-coupling 2 has a second transmission groove 5 at one end. The cross slide 3 has a first transmission seat 6 at one end, which is movably sleeved into the inner cavity of the first transmission groove 4. The cross slide 3 has a second transmission seat 7 at the other end, which is movably sleeved into the inner cavity of the second transmission groove 5. Both the first half-coupling 1 and the second half-coupling 2 are provided with two lubrication mechanisms 8.

[0026] For details, please refer to Figure 1 , Figure 3 and Figure 4 The lubrication mechanism 8 includes powder storage tanks 9 respectively opened inside the first half coupling 1 and the second half coupling 2. The inner wall of each powder storage tank 9 is provided with stepped threaded holes 10. The inner cavity of the stepped threaded holes 10 is threaded with internal hex bolts 14. Powder outlet holes 11 are respectively opened at both ends of the inner cavity of the powder storage tank 9.

[0027] In this embodiment, the powder outlet 11 on the side of the powder storage tank 9 on the first half coupling 1 is connected to the inner cavity of the first transmission groove 4, and the powder outlet 11 on the side of the powder storage tank 9 on the second half coupling 2 is connected to the inner cavity of the second transmission groove 5. In addition, the inner cavity of the powder storage tank 9 is provided with lead powder, and lead powder can be added to the powder storage tank 9 through the stepped threaded hole 10 by removing the internal hex bolt 14.

[0028] For details, please refer to Figure 1 The first half-coupling 1 and the second half-coupling 2 are both provided with shaft connection holes 12 in the middle, and fixed threaded holes 13 are provided on the side of the other end of the first half-coupling 1 and the second half-coupling 2.

[0029] In this embodiment, by inserting two connecting shafts into the shaft connecting hole 12 and by inserting bolts into the fixing thread hole 13 and the connecting hole on the connecting shaft, the first half coupling 1 and the second half coupling 2 are connected to the two connecting shafts.

[0030] For details, please refer to Figure 3 and Figure 5 The first transmission groove 4 has a first outward inclined slope 15 on both sides of its inner cavity, and the first transmission seat 6 has a first outward inclined angle 17 on both sides.

[0031] For details, please refer to Figure 4 and Figure 5 The second transmission groove 5 has a second outward inclined slope 16 on both sides of its inner cavity, and the second transmission seat 7 has a second outward inclined angle 18 on both sides.

[0032] In this embodiment, the cooperation between the second outer inclined slope 16 and the second outer inclined angle 18 allows for a certain degree of misalignment between the second half coupling 2 and the cross slide 3. At the same time, the cooperation between the first outer inclined slope 15 and the first outer inclined angle 17 allows for a certain degree of misalignment between the first half coupling 1 and the second half coupling 2. This provides angular compensation between the two shafts, enabling the adaptation to larger angular deviations between the two shafts. The greater angular compensation capability can effectively reduce the wear of the reamer, thereby increasing the service life of the equipment.

[0033] For details, please refer to Figure 1 The first half-coupling 1, the second half-coupling 2, and the cross slide 3 are all made of high-strength wear-resistant materials.

[0034] In this embodiment, the service life of the first half-coupling 1, the second half-coupling 2, and the cross slide 3 is guaranteed.

[0035] Working principle: In use, firstly, the first half-coupling 1 and the second half-coupling 2 are connected to the reducer shaft and the reamer shaft respectively through the shaft connection hole 12, the fixing thread hole 13, and the bolts. Simultaneously, a cross slide 3 is placed between the first half-coupling 1 and the second half-coupling 2, with the first transmission seat 6 at one end of the cross slide 3 inserted into the first transmission groove 4, and the second transmission seat 7 at the other end of the cross slide 3 inserted into the second transmission groove 5. Then, the hexagon socket head cap screw 14 is removed, and lead powder is placed into the powder storage tank 9 through the stepped thread hole 10. Subsequently, hexagon socket head cap screws 14 are installed on the stepped thread hole 10 to seal it. Finally, the reducer shaft drives the first half-coupling 1 to rotate, and the cross slide 3 rotates through the engagement between the first transmission groove 4 and the first transmission seat 6, and through the second transmission groove 5 and the second transmission seat 7... The interaction between the two drives the second half coupling 2 to rotate, which in turn drives the reamer to rotate. During the rotation of the first half coupling 1 and the second half coupling 2, the lead powder in the powder storage tank 9 enters the first transmission groove 4 and the second transmission groove 5 through the powder outlet 11. This lubricates the first transmission groove 4 and the first transmission seat 6, the second transmission groove 5 and the second transmission seat 7, reducing wear between them. In addition, a certain degree of misalignment can occur between the first transmission groove 4 and the first transmission seat 6, the second transmission groove 5 and the second transmission seat 7, thus providing angular compensation between the reducer shaft and the reamer shaft. This allows for adaptation to larger angular deviations between the two shafts, and the greater angular compensation capability can effectively reduce reamer wear, thereby increasing the service life of the equipment.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
