Description

Technical Field

[0001] The utility model relates to the technical field of particle forming equipment, in particular to a gear transmission box cooling mechanism of horizontal particle forming equipment. Background Art

[0002] In existing pellet forming equipment, particularly horizontal pellet forming equipment, the gearbox, as a core component, generates significant heat under prolonged, high-load operation. This heat primarily originates from friction within the gears, bearings, and oil seals within the gearbox, as well as from the relative motion between the die and rollers. If left uncontrolled, this heat can lead to excessively high internal gearbox temperatures, disrupting normal equipment operation and potentially causing problems such as increased gear wear, bearing failure, and oil seal aging, shortening the equipment's service life and increasing maintenance costs.

[0003] While some pellet forming equipment currently on the market is equipped with simple cooling measures, these are often ineffective and unable to meet the cooling requirements of long-term, continuous operation. Traditional cooling methods rely on either natural heat dissipation or simple air cooling systems. These methods are inefficient in high-heat environments and cannot effectively control the internal temperature of the gearbox. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a gear transmission box cooling mechanism for a horizontal particle forming device to solve the problems in the background technology.

[0005] In view of this, the utility model provides a gear transmission box cooling mechanism for a horizontal particle forming equipment, comprising:

[0006] the gearbox, which contains the gears, bearings, and oil seals;

[0007] A ring die and a pressure roller are provided on the gear box, wherein the ring die and the pressure roller generate heat during operation;

[0008] A box body partition is formed in the gear box. A copper tube is provided in the box body partition. One end of the copper tube is connected to a water inlet joint, and the other end is connected to a water outlet joint.

[0009] Optionally, cooling water enters the copper tube through the water inlet joint and performs heat exchange with the lubricating oil in the box interlayer, thereby reducing the temperature in the gear box.

[0010] Optionally, the copper tube is arranged in the box interlayer to increase the contact area with the lubricating oil and improve the heat exchange efficiency.

[0011] Optionally, the cooling water is discharged through the water outlet joint, treated by an external cooling device, and then re-injected into the copper pipe through the water inlet joint.

[0012] Optionally, the external cooling device is a water cooling tower.

[0013] Optionally, the cooling mechanism is used to reduce the temperature of the gearbox from 80°C to below 40°C, thereby extending the service life of the gears, bearings, oil seals and lubricating oil.

[0014] It can be seen from the above technical solutions that the embodiments of the present invention have the following advantages:

[0015] 1. The utility model discloses a gear transmission box cooling mechanism for horizontal pellet forming equipment. Through heat exchange between the copper tube and the lubricating oil, the temperature inside the gear box can be quickly reduced, effectively controlled within a safe range, and mechanical failures caused by high temperature can be avoided. By controlling the temperature inside the gear box, the service life of the gears, bearings, oil seals and lubricating oil can be significantly extended, the replacement frequency can be reduced, and the maintenance cost can be reduced.

[0016] 2. The utility model discloses a horizontal particle forming equipment gear transmission box cooling mechanism, which uses a cooling water circulation system. The cooling water can be reused after being treated by an external cooling tower, which reduces the consumption of water resources and is also beneficial to environmental protection.

[0024] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0025] The following describes in detail a gear transmission box cooling mechanism of a horizontal particle forming equipment according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0026] Example

[0027] For easier understanding, see Figures 1 to 4 The present invention provides an embodiment of a cooling mechanism for a gear transmission box of a horizontal particle forming device, comprising:

[0028] Gearbox 1, which contains gears 4, bearings 5 and oil seals 6;

[0029] The ring die 2 and the pressure roller 3 are arranged on the gear box 1, and the ring die 2 and the pressure roller 3 generate heat during operation;

[0030] A box body partition 7 is formed in the gear box 1 , and a copper tube 8 is provided in the box body partition 7 . One end of the copper tube 8 is connected to a water inlet joint 9 , and the other end is connected to a water outlet joint 10 .

[0031] It should be noted that the gearbox 1 contains gears 4, bearings 5, and oil seals 6, which generate heat due to friction during operation. Furthermore, the ring die 2 and pressure roller 3 are mounted on the gearbox 1, which also generate a large amount of heat during operation.

[0032] In some embodiments, cooling water enters the copper tube 8 through the water inlet connector 9 and exchanges heat with the lubricating oil in the box interlayer 7, thereby reducing the temperature inside the gearbox 1. The copper tube 8 is arranged in the box interlayer 7 to increase the contact area with the lubricating oil and improve the heat exchange efficiency.

[0033] It should be noted that a housing interlayer 7 is provided within the gearbox 1, embedded within which is a copper tube 8 made of a material with excellent thermal conductivity. One end of the copper tube 8 is connected to a water inlet connector 9, and the other end is connected to a water outlet connector 10. This allows cooling water to enter the copper tube 8 through the water inlet connector 9 and then exit through the water outlet connector 10, effectively controlling the temperature within the gearbox 1. After entering the copper tube 8, the cooling water exchanges heat with the lubricating oil in the housing interlayer 7. The increased contact area between the copper tube 8 and the lubricating oil improves heat exchange efficiency, thereby effectively reducing the temperature within the gearbox 1.

[0034] In some embodiments, the cooling water is discharged through the water outlet joint 10, treated by an external cooling device, and then re-injected into the copper pipe 8 through the water inlet joint 9. The external cooling device is a water cooling tower.

[0035] It should be noted that after passing through the gearbox interlayer 7 and absorbing heat, the cooling water is discharged from the gearbox 1 through the water outlet connector 10. The hot water is then sent to an external cooling device, such as a water cooling tower, for cooling. The treated cooling water is then re-injected into the copper pipe 8 through the water inlet connector 9, forming a closed-loop cooling circulation system.

[0036] In some embodiments, the cooling mechanism is used to reduce the temperature of the gearbox 1 from 80°C to below 40°C, thereby extending the service life of the gear 4, bearing 5, oil seal 6 and lubricating oil, and ensuring the stable operation of the entire particle forming equipment.

[0037] Working Principle: In the pelletizing machine, the ring die 2 and roller 3 are mounted on the gearbox 1. They move relative to each other during the pelletizing process, compacting the raw materials. This movement causes friction between the ring die 2 and roller 3, as well as between them and other components within the gearbox 1, generating heat. This heat is transferred through the ring die 2 and roller 3 structure to components such as the oil seal 6, bearing 5, and gear 4. Since the gearbox 1 is filled with lubricating oil, these high-temperature components come into contact with the lubricating oil and transfer their heat to it. The lubricating oil flows within the gearbox 1 and through the housing interlayer 7, which houses a copper tube 8 with excellent thermal conductivity. Cooling water is injected into the copper tube 8 through the water inlet connector 9, bringing the surface temperature of the copper tube 8 close to that of the cooling water. As the high-temperature lubricating oil flows over the surface of the copper tube 8, heat is transferred to the cooling water within the copper tube 8, thereby cooling the lubricating oil. As the lubricating oil exchanges heat with the surface of the copper tube 8, the temperature of the cooling water inside the copper tube 8 gradually increases. The heated cooling water is discharged from the gear box 1 through the water outlet joint 10 and is transported to the external water cooling tower for cooling treatment. The temperature of the cooling water after treatment in the cooling tower drops, and then it is reintroduced into the copper tube 8 through the water inlet joint 9 to continue the cooling cycle. Through the above-mentioned continuous heat exchange process, the temperature inside the gear box 1 can be effectively controlled, reducing the high temperature that may reach 80°C to 40°C or lower. This temperature control measure helps to protect key components such as gears 4, bearings 5, and oil seals 6 from overheating damage, and extends the service life of the lubricating oil, thereby ensuring the long-term and stable operation of the particle forming equipment.

[0038] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
