Description

Technical Field

[0001] This utility model relates to the field of drying equipment, and in particular to a TNT high and low temperature drum heating device. Background Technology

[0002] TNT is a flammable and explosive material. After preparation, it needs to be dried before storage. Existing drum heating devices are designed for conventional materials and do not have high requirements for fire prevention and anti-static properties. Therefore, their structural design cannot meet the needs of TNT production. Currently, for flammable and explosive materials like TNT, vacuum chamber drying is mostly used. TNT is dried in a vacuum environment with inert gas, which offers good safety. The disadvantage is that the vacuum chamber is a separate device, requiring manual transfer before and after drying, which is cumbersome. Moreover, the vacuum chamber is limited by size and has a small processing capacity, making it unsuitable for large-scale continuous production lines. Therefore, we need to design a drying device that meets the production requirements of TNT, has high safety, and can achieve large-scale continuous production of TNT. Utility Model Content

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] (1) This utility model dries TNT material by using a water bath heating drum. The TNT material can be dried quickly during the tumbling process inside the heating drum. It can achieve large-scale continuous production of TNT material by feeding from one end and discharging from the other end. It does not need to be dried and sent to the storage silo through the discharge pipe. It is very convenient as it does not require manual transfer.

[0016] (2) Since the heating drum needs to rotate during operation, the structural design of the part connected to the rotating heating drum in the device is very important. In order to avoid affecting the water inlet pipe and the feed pipe from entering the heating drum, and to facilitate the drainage and feeding of the heating drum, and to ensure that no sparks are generated during the rotation of the heating drum, feed hoods and discharge hoods are provided at both ends of the heating drum. The feed hoods and discharge hoods are provided with windows to facilitate the insertion of the heating drum at both ends. After the heating drum is mounted by the roller positioning bracket, both ends are suspended in the feed hoods and discharge hoods and will not contact the feed hoods and discharge hoods, so as to avoid sparks generated by the rotation friction. Meanwhile, the feed hood and discharge hood also serve to collect the heated cooling water and TNT material. The water outlet pipe and discharge pipe are respectively connected to the bottom of the feed hood and discharge hood. The heated cooling water flows out from the outer wall of the feed end of the heating drum, enters the feed hood and collects, and is discharged from the water outlet pipe at the bottom. The heated TNT material is discharged from the discharge end of the heating drum, falls into the discharge hood, and is discharged through the discharge pipe.

[0017] (3) The water inlet end of the water inlet pipe is provided with a rotary joint. The water inlet pipe is connected to the water supply pipe through the rotary joint.

[0028] The present invention will be further described below: A TNT high and low temperature drum heating device, see [link to relevant documentation]. Figures 1 to 7 The device includes a frame 1, an inlet pipe 7, an outlet pipe 8, a feed pipe 5, an outlet pipe 6, a heating drum 2, a roller positioning bracket 4, and a drive device 3 for rotating the heating drum 2. The heating drum 2 is mounted on the frame 1 via the roller positioning bracket 4. The heating drum 2 has a feed cover 9 and an outlet cover 10 at both ends, which are fixed to the frame 1 by brackets. The feed end and the outlet end of the heating drum 2 are suspended inside the feed cover 9 and the outlet cover 10, respectively. The feed cover 9 has a window on its side to facilitate the insertion of the feed pipe 5. The outlet pipe 8 is connected to the bottom of the feed cover 9. The outlet cover 10 has a window on its side to facilitate the insertion of the feed pipe 7. The outlet pipe 6 is connected to the bottom of the outlet cover 10. The top of both the feed cover 9 and the outlet cover 10 is equipped with a ventilation pipe 15. During operation, TNT material enters the heating drum 2 through the feed pipe 5, is heated and dried by the heating drum 2, and is discharged from the discharge end of the heating drum 2.

[0029] Since the material being heated in this invention is TNT, the requirements for fireproofing, explosion-proofing, and anti-static properties of the equipment are extremely high. Because the heating drum 2 rotates, to avoid interfering with the insertion of the water inlet pipe 7 and the feed pipe 5 into the heating drum 2, and to facilitate drainage and material discharge, and to prevent sparks from being generated during the rotation of the heating drum 2, feed hoods 9 and discharge hoods 10 are respectively provided at both ends of the heating drum 2. The feed hoods 9 and 10 have windows that allow the heating drum 2 to be inserted at both ends. After being supported by the roller positioning bracket 4, the heating drum 2 is suspended at both ends within the feed hoods 9 and 10, preventing contact with them and avoiding sparks generated by friction during rotation. Because the water inlet pipe 7 rotates with the heating drum 2, the discharge hood 10 also has the same window to prevent sparks from being generated by contact friction.

[0030] Simultaneously, the feed hood 9 and discharge hood 10 also serve to collect the heated cooling water and TNT material. The water outlet pipe 8 and discharge pipe 6 are respectively connected to the bottom of the feed hood 9 and discharge hood 10. The heated cooling water flows out from the outer wall of the feed end of the heating drum 2, enters the feed hood 9, collects, and then discharges from the bottom water outlet pipe 8. The heated TNT material is discharged from the discharge end of the heating drum 2, falls into the discharge hood 10, and is discharged through the discharge pipe 6. The parts of the discharge hood 10 that are in direct contact with the material are made of 316 stainless steel plates and profiles. The surface of the stainless steel plates is smooth, which facilitates material handling and prevents TNT adhesion. Other parts are made of high-quality carbon steel, and the surface is powder-coated to prevent static electricity.

[0031] To prevent TNT material from overflowing from the discharge end of the heating drum 2, a negative pressure conveying method is used. The TNT material is transported to the negative pressure storage chamber through the discharge pipe 6. A ventilation pipe 15 is installed at the top of the discharge hood 10 to facilitate the introduction of outside air. The vapor generated by the evaporation of TNT material will be discharged from the feed end; therefore, a ventilation pipe 15 is installed at the top of the feed hood 9 to facilitate the discharge of water vapor. To prevent sparks from occurring at the connection between the ventilation pipe 15 and the feed hood 9 and discharge hood 10, the ventilation pipe 15 is made of anti-static canvas material.

[0032] The water inlet pipe 7 is provided with a rotary joint 11 at the water inlet end. The water inlet pipe 7 is connected to the water supply pipe 12 through the rotary joint 11. Since the water inlet pipe 7 will rotate with the heating drum 2, the rotary joint 11 is used to connect the water inlet pipe 7 and the water supply pipe 12, so that the water supply process is not affected by the water inlet pipe 7.

[0033] In order to control the drying effect of TNT, the feed end of the feed pipe 5 is equipped with a distribution funnel 13. The feed amount can be precisely controlled by the distribution funnel 13 to achieve better material drying.

[0034] The frame 1 consists of a mounting platform 101 and height-adjustable legs 102. The legs 102 can adjust the horizontal height of the mounting platform 101 to ensure that the heating drum 2 is at a set horizontal height. The bottom of the mounting platform 101 is equipped with an angle adjustment mechanism 16 for fine-tuning the tilt of the mounting platform 101. By adjusting the mounting platform 101 through the angle adjustment mechanism 16, the feed end of the heating drum 2 can be raised, causing the heating drum 2 to tilt, facilitating the discharge of heated material from the discharge end of the heating drum 2, and the generated steam to be discharged from the feed end. The main body of the angle adjustment mechanism 16 is made of high-quality carbon steel with a powder-coated or QPQ treated surface, and its transmission gears are made of copper alloy. The main body of the frame 1 is made of high-quality carbon steel profiles and plates, with a painted surface to prevent static electricity.

[0035] The drive device 3 consists of an explosion-proof motor 31, a reducer 32, and a drive gear 33. The heating drum 2 has a driven gear 25 in the middle that meshes with the drive gear 33. The explosion-proof motor 31 is connected to the driven gear 25 of the heating drum 2 through the reducer 32 and the drive gear 33 to realize the rotation of the heating drum 2. The drive gear 33 is made of copper alloy, and the driven gear 25 is made of 304 stainless steel. The explosion-proof rating of the explosion-proof motor 31 is Exd IIB T4.

[0036] At least two sets of roller positioning brackets 4 are symmetrically arranged at the front and rear sections of the heating roller 2. Each section of the heating roller 2 has an annular roller ring 26. Each roller positioning bracket 4 has a set of radial positioning rollers 41 and an axial positioning roller 42. The radial positioning rollers 41 are arranged at an angle. The roller ring 26 of the heating roller 2 rests on the radial positioning rollers 41. During the rotation of the heating roller 2, the radial positioning rollers 41 provide radial positioning and guidance for the heating roller 2. The roller ring 26 is made of 304 stainless steel. The axial positioning roller 42 is located on the side of the roller ring 26 and provides axial positioning for the heating roller 2, preventing it from shifting forward or backward.

[0037] The drive gear 33 and the driven gear 25 are equipped with a detachable protective cover 14. The roller positioning bracket 4 and the rolling ring 26 are also equipped with a detachable protective cover 14. The protective cover 14 protects the internal components. The protective cover 14 is made of ordinary carbon steel and has a powder-coated anti-static treatment.

[0038] Heating roller 2 is a water bath type heating roller 2. As a preferred option, our company's TNT heating roller 2 can be used. See [link / reference]. Figure 8The heating drum 2 is a double-layered cylindrical structure consisting of an outer layer 21 and an inner layer 22. The inner layer 22 serves as a TNT material channel 24, and the interlayer between the outer layer 21 and the inner layer 22 is a water channel 23. One end of the heating drum 2 has an inlet connected to the TNT material channel 24, and the other end has an outlet connected to the TNT material channel 24. A water inlet pipe 7 is installed inside the outlet, and the water inlet pipe 7 is connected to the interior of the water channel 23. The outer layer 21 of the heating drum 2 has an annular water outlet plate at its inlet end, and water outlet holes connected to the interior of the water outlet plate are opened on the outer layer 21. Water outlets are located around the perimeter of the water outlet plate. Hot water at a certain temperature is introduced into the water channel 23, and the TNT material flows from the water channel 23 in the opposite direction into the material channel, achieving physical heating and drying of the TNT. Simultaneously, a motor drive device 3 drives the heating drum 2 to rotate, causing the material within the TNT material channel 24 to tumble and accelerate the drying process, thereby achieving uniform heating of the TNT material.
