Description

Technical Field

[0001] This utility model belongs to the technical field of cooling devices, specifically relating to a cooling device for the discharge of a dry tube ball mill. Background Technology

[0002] A tube ball mill is a continuous coarse powder (average particle size 5-10μm) grinding device, consisting of a motor drive mechanism, a grinding cylinder, and grinding media (such as steel balls, zirconia balls, etc.). Due to its simple structure and ease of manufacture, it is widely used in the production industry of permanent magnet ferrite materials.

[0003] During operation, the material to be ground enters the ball mill from one end. As the grinding media inside the ball mill rotates with the cylinder, it rolls or rises to a certain height and falls. After being crushed and subjected to mutual friction until its particle size decreases to a certain level, it is discharged from the outlet. The pulverized material is then filtered by a screening machine to remove coarse particles before being conveyed to a quantitative packaging unit for packaging and warehousing. Due to the friction between materials and between the grinding media, the output material from the dry ball mill has a high temperature, generally exceeding 100℃. This affects the normal operation of subsequent process equipment (such as screening machines, powder conveying bucket elevators, finished product packaging, etc.), causing frequent equipment failures (such as motor overheating and damage, screen breakage, etc.) and rapid aging of the woven packaging, which is detrimental to stable production. Conventional heat exchangers, on the other hand, have problems with short lifespan (wear leading to perforation of the heat exchange surface) and easy clogging of channels when handling solid powders containing larger particles. To avoid the above problems, the screens are replaced every 3-5 days during production. Forced ventilation and heat dissipation are applied to the motors of the screening machine and bucket elevator. The packaged products are laid flat on the ground and forced to cool down (2-3 hours). After cooling, they are then stored and stacked. The operation process occupies a large area, is labor-intensive, and takes a long time. Utility Model Content

[0023] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0024] The dry tube ball mill discharge cooling device of this embodiment refers to... Figure 1 It includes the device body 6, the tilt adjustment device 3, the heat exchange assembly 4, and the fixed base 5; In some embodiments, the device body 6 is provided with a plurality of angle-adjustable heat exchange components 4; one end of each heat exchange component 4 is movably mounted on the inner wall of the device body 6 via a fixed base 5, and the other end of the heat exchange component 4 is connected to the tilt angle adjustment device 3; the tilt angle of the heat exchange component 4 can be adjusted by the cooperation of the tilt angle adjustment device 3 and the fixed base 5; the medium inflow pipe 1 passes through the tilt angle adjustment device 3 and is connected to the air inlet end of the heat exchange component 4, and the air outlet pipe of the heat exchange component 4 is connected to the medium outflow pipe 2 passing through the fixed base 5.

[0025] In one specific embodiment, reference is made to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 The tilt adjustment device 3 includes a support rod 32, which is a hollow structure for the medium inflow pipe 1 to pass through. A medium pipeline passage 31 is provided on the support rod for the medium inflow pipe 1 to pass through and exit. One end of the support rod 32 passes through a displacement groove 9 on the inner wall of the device body 6 and an opening on the sealing plate 7, and is fixed by a locking screw 34 and a nut. The displacement groove 9 is vertically oriented, allowing the support rod 32 to extend and retract within it. The length of the support rod 32 extending out of the device body 6 is adjustable. Based on the displacement groove 9, the support rod 32 can extend and retract while simultaneously moving vertically, thereby adjusting the tilt angle of the heat exchange component 4. The sealing plate 7 has only holes; after the support rod 32 has completed its displacement, the sealing plate 7 is placed over the displacement groove 9.

[0026] The other end of the support rod 32 is provided with a first threaded hole 33, which is connected to the adjusting seat 41 on the heat exchange assembly 4.

[0027] In one specific embodiment, reference is made to Figure 2 , Figure 3 and Figure 6 The adjusting seat 41 includes two spaced triangular plates, each with a second threaded hole. Bolts pass through one second threaded hole, the first threaded hole 33 on the support rod 32, and the other second threaded hole in sequence to connect the support rod 32 and the adjusting seat 41.

[0028] In one specific embodiment, reference is made to Figure 6 The heat exchange component 4 is a hollow plate structure with a heat exchange surface 45 at its upper end and an adjusting seat 41 and a medium distributor 43 at its lower end. Multiple heat sinks 42 are installed inside the heat exchange component 4. The medium inflow pipe 1 passes through one end of the support rod 32 and exits through the medium pipe channel 31 at the other end of the support rod 32, connecting with the medium inlet 44 on the medium distributor 43, thereby introducing the cooling medium into the heat exchange component 4. The cooling medium can be nitrogen or other inert gases.

[0029] Among them, the medium distributor 43 is existing technology.

[0030] In one specific embodiment, reference is made to Figure 7 The top surface of the plate-like structure has a mounting plate 51 on each of its two edges. The two mounting plates 51 are located on the two inner walls of the device body 6, and each mounting plate 51 has a mounting hole, which is connected to the fixing seat 5.

[0031] In one specific embodiment, reference is made to Figure 7 The fixed base 5 includes a crossbar 53, and the two ends of the crossbar 53 are respectively movably inserted into the mounting holes on the two mounting plates 51 on the top of the heat exchange assembly 4.

[0032] A hole is provided on the inner wall of the device body 6. The screw 52 passes through this hole and is threadedly connected to the crossbar 53 located in a mounting hole. The other end of the crossbar 53 passes through another mounting hole and the inner wall of the device body 6 in sequence and extends to the outside of the device body 6. There is no tight contact between the screw 52 and the outer wall of the device body 6. There is a certain gap between the two. That is, the screw 52 is used for limiting and preventing the crossbar 53 from falling off when rotating. In other words, the entire heat exchange assembly 4 is movably mounted on the crossbar 53 through the mounting plate 51 and can rotate along the crossbar 53.

[0033] In one specific embodiment, the crossbar 53 is hollow inside, and the hollow structure extends to one end of the crossbar 53. A flexible hose 8 is provided inside the hollow structure. A crossbar medium outlet pipe 54 is opened on the crossbar 53 located inside the device body 6. One end of the flexible hose 8 is connected to the inside of the heat exchange component 4, and the other end is connected to the medium outlet pipe 2.

[0034] In one specific embodiment, when adjusting the angle of the heat exchange component 4, the locking screw 34 and the corresponding nut on the support rod 32 are removed, and the sealing plate 7 is removed at the same time. The tilt angle of the heat exchange component 4 is changed by moving the length of the support rod 32 within the device body 6 (at this time, the top of the heat exchange component 4 can rotate directly on the crossbar 53). The vertical movement space of the support rod 32 is provided by the displacement groove 9. After the heat exchange component 4 is moved into place, the hole on the sealing plate 7 is aligned with the support rod 32 and passed through it, and then locked by the locking screw 34.

[0035] In one specific embodiment, during material cooling, the material falls from the opening above the device body 6 and passes through the heat exchange surfaces 45 of multiple heat exchange components 4 for heat exchange. The cooling gas is provided by other equipment connected to the medium inflow pipe 1. The medium inflow pipe 1 passes through the support rod 32 and is connected to the medium inlet 44 on the medium distributor 43 through the medium pipeline channel 31, thereby introducing the cooling gas into the heat sink 42 inside the heat exchange component 4 for heat exchange. The gas (cooling gas) after heat exchange flows out from the hose 8 at the top of the heat exchange component 4. The hose 8 is connected to the medium outlet pipe 2 through the crossbar medium outlet pipe 54, thereby discharging the heat-exchanged gas.

[0036] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
