Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a transmission bearing cooling device for a battery crusher. Background Art

[0002] A battery is a power supply device that has a stable voltage, can supply power for a long time, and is less affected by the outside world. Most of the waste batteries are crushed by a crusher and then separated by a separation process to separate the positive / negative electrode materials and valuable metals to obtain positive and negative electrode mixed powder, copper powder, aluminum powder, iron powder, etc., to achieve battery recycling and reuse.

[0003] During the operation of the crusher, the transmission bearing of the crusher will generate high temperature due to friction and needs to be cooled. The existing cooling method is mostly to cool the bearing by applying lubricating oil. However, in actual application, the expected cooling effect cannot be achieved by relying solely on lubricating oil, which leads to the burning accident of the transmission bearing due to excessive internal temperature, thereby reducing the service life of the sliding bearing.

[0004] Although some transmission bearings have water cooling mechanisms, there is still a problem that the cooling method is single and the expected effect cannot be achieved. At the same time, the water cooling mechanism often needs to be equipped with a water cooling box / pool, which occupies a large area, and the used cooling water and the cooling water to be used are directly mixed, causing the water temperature in the water cooling box / pool to gradually rise;

[0005] In view of this, there is an urgent need for a battery crusher transmission bearing cooling device that can solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a battery crusher transmission bearing cooling device which solves the above-mentioned problem.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme, a battery crusher transmission bearing cooling device, comprising:

[0008] The machine body shell, the transmission shaft, the bearing and the cooling assembly, the bearing and the transmission shaft are movably connected at one end inside the machine body shell, and the cooling assembly is connected to the machine body shell.

[0009] Preferably, the cooling assembly includes a cooling pipe, a coolant tank and a water pump. An annular mounting groove for installing the cooling pipe is provided on the side wall of the body shell on the side in contact with the bearing. Both ends of the cooling pipe pass through the body shell and are located outside it, and the water inlet end of the cooling pipe is connected to the water pump, the water outlet end of the cooling pipe is connected to the coolant tank, and the water pump is connected to the coolant tank.

[0010] Preferably, a partition is provided in the coolant box body to separate it into an upper layer and a lower layer, and a coolant flow hole is provided on the partition body, and a liquid level control component is provided in the lower layer of the coolant box body, and the liquid level control component is movably connected to the coolant flow hole.

[0011] Preferably, the liquid level control assembly includes a floating plate, a hollow sleeve, a sliding plate, a spring, a connecting rod and a sealing plate. The hollow sleeve is fixedly connected to the floating plate, the sliding plate and the spring are located in the hollow sleeve, the lower end of the connecting rod passes through the top wall of the hollow sleeve and the spring and is fixedly connected to the sliding plate, the upper end of the connecting rod is fixedly connected to the sealing plate, and the connecting rod is slidably connected to the hollow sleeve.

[0012] Preferably, a sleeve fixedly connected to the lower end of the floating plate is provided, and the other end of the sleeve is fixedly connected to the bottom of the lower layer of the coolant tank.

[0013] Preferably, the plane side wall of the machine shell is mesh-shaped, and the transmission shaft is located on the inner side of the machine shell and is provided with at least one set of exhaust fans detachably connected thereto.

[0014] Preferably, a cooling sleeve fixedly connected to the machine body shell is provided inside the machine body shell, the cooling sleeve is located between the inner wall of the machine body shell and the bearing, and a plurality of temperature conduction rods are provided on the cooling sleeve, the temperature conduction rods pass through the machine body shell and are located outside the machine body shell.

[0015] Preferably, an arc-shaped cooling groove is provided on the inner wall of the body shell, the width of the arc-shaped cooling groove is smaller than the width of the bearing, and the curvature of the arc-shaped cooling groove is less than 300°; a liquid inlet through hole and a liquid outlet through hole are provided on the side wall of the arc-shaped cooling groove, and matching sealing rings are provided in the liquid inlet through hole and the liquid outlet through hole.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. Cooling liquid is used for cooling on the basis of the original lubricating oil cooling. At the same time, the cooling method is further expanded by enhancing the air flow in the body shell and using a cooling sleeve made of heat-conducting material. It can be used in combination or alone according to actual conditions, which optimizes the cooling effect on the transmission bearing.

[0018] 2. The traditional coolant tank is improved by using baffles and liquid level control components. This not only effectively reduces the footprint of the traditional coolant tank, but also prevents the coolant discharged from the outlet end of the cooling pipe from directly mixing with the coolant drawn into the inlet end of the cooling pipe. In other words, the discharged coolant will only be used again after a natural cooling process, which indirectly improves the water cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Embodiment 1

[0031] Please see attached Figure 1-3 , a battery crusher transmission bearing cooling device, comprising:

[0032] A machine body shell 1, a transmission shaft 2, a bearing 3 and a cooling assembly 4, wherein the bearing 3 is movably connected to one end of the transmission shaft 2 located in the machine body shell 1, and the cooling assembly 4 is connected to the machine body shell 1.

[0033] Specifically, the cooling assembly 4 includes a cooling pipe 40, a coolant tank 41 and a water pump. An annular mounting groove 10 for mounting the cooling pipe 40 is provided on the side of the body shell 1 that contacts the bearing 3. Both ends of the cooling pipe 40 pass through the body shell 1 and are located outside it, and the water inlet end of the cooling pipe 40 is connected to the water pump, and the water outlet end of the cooling pipe 40 is connected to the coolant tank 41, and the water pump is connected to the coolant tank 41; through the annular mounting groove 10 provided in the body shell 1, the cooling pipe 40 inserted into the body shell 1 can be spirally arranged on the bearing sleeve of the bearing 3, and temperature conduction is carried out through the contact between the cooling pipe 40 and the bearing sleeve, thereby achieving cooling of the bearing 3.

[0034] Specifically, the coolant tank 41 is provided with a partition 410 for separating it into an upper layer and a lower layer, the partition 410 is provided with a coolant flow hole 411, and the lower layer of the coolant tank 41 is provided with a liquid level control component 42, and the liquid level control component 42 is movably connected to the coolant flow hole 411; taking water as an example of the coolant, by dividing the coolant tank 41 into an upper layer for drainage and cooling and a lower layer for pumping water, firstly, the footprint of the coolant tank 41 is reduced, and secondly, the discharged water and the water to be pumped are separated, which indirectly avoids the situation where the temperature of the water to be pumped increases due to direct mixing.

[0035] Specifically, the liquid level control component 42 includes a floating plate 420, a hollow sleeve 421, a sliding plate 422, a spring 423, a connecting rod 424 and a blocking plate 425. The hollow sleeve 421 is fixedly connected to the floating plate 420, the sliding plate 422 and the spring 423 are located in the hollow sleeve 421, the lower end of the connecting rod 424 passes through the top wall of the hollow sleeve 421 and the spring 423 and is fixedly connected to the sliding plate 422, and the upper end thereof is fixedly connected to the blocking plate 425, and the connecting rod 424 is slidably connected to the hollow sleeve 421; the liquid level control component 42 physically monitors the liquid level position of the lower layer of the coolant tank 41 by using the buoyancy characteristics of the floating plate 420. In the process of the liquid level dropping after the coolant is pumped out, , the floating plate 420 will drive the hollow sleeve 421 to move downward. During this process, the top wall of the hollow sleeve 421 will first contact the spring 423 and further compress the spring 423. After the spring 423 is compressed to the limit, the connecting rod 424 will drive the blocking plate 425 to move downward. When the blocking plate 425 is out of contact with the coolant flow hole 411, the coolant in the upper layer will flow to the lower layer. During this process, the coolant level in the lower layer gradually rises, and the floating plate 420 moves upward. During the movement, the force applied to the spring 423 will gradually decrease, so that the spring 423 will change from the compression process to the normal state and then to the stretched state. After being stretched to the limit, the blocking plate 425 will be driven upward by the connecting rod 424, and finally the coolant flow hole 411 will be blocked again.

[0036] The process of the spring 423 changing from a compressed state to a stretched state is the state in which the coolant flow hole 411 is open, that is, the process in which the coolant flows from the upper layer to the lower layer, and the process of changing from a stretched state to a compressed state is the state in which the coolant flow hole 411 is closed, that is, a process in which the discharged coolant is naturally cooled.

[0037] Specifically, the lower end of the floating plate 420 is provided with a sleeve 426 fixedly connected thereto, and the other end of the sleeve 426 is fixedly connected to the bottom of the lower layer of the coolant tank 41; in order to avoid the situation where the blocking plate 425 and the coolant flow hole 411 are misaligned and cannot be blocked, the sleeve 426 is used to correct and fix the vertical position of the floating plate 420. It should be noted that the attached Figure 3 The ratio of the middle liquid level control assembly 42 to the coolant tank 41 does not represent the ratio between the two in actual applications.

[0038] Embodiment 2

[0039] Please see attached Figure 4-5

[0040] Specifically, the plane side wall of the body shell 1 is mesh-shaped, and the transmission shaft 2 is located on the inner side of the body shell 1 and is provided with at least one group of exhaust fans 11 detachably connected thereto; by providing the exhaust fan 11 on the inner side of the transmission shaft 2 on the body shell 1, the air flow inside the body shell 1 is further improved to achieve the purpose of cooling, and the mesh structure of the side wall of the body shell 1 is set to ensure that there is no flow obstacle to the gas inside and outside the body shell 1.

[0041] Embodiment 3

[0042] Please see attached Figure 6-7

[0043] Specifically, the body shell 1 is provided with a cooling sleeve 12 fixedly connected thereto, the cooling sleeve 12 is located between the inner wall of the body shell 1 and the bearing 3, and a plurality of temperature conduction rods 120 are provided on the cooling sleeve 12, and the temperature conduction rods 120 pass through the body shell 1 and are located outside thereof; by arranging the cooling sleeve 12 between the body shell 1 and the bearing 3, the temperature reduction of the bearing 3 is accelerated directly by contact, and the temperature of the bearing 3 can be directly conducted to the outside of the body shell 1 by the arrangement of the plurality of temperature conduction rods 120. It should be noted that in this method, the material of the cooling sleeve 12 has certain requirements, and its thermal conductivity must be greater than that of the body shell 1. Considering that the body shell 1 is generally made of steel, the cooling sleeve 12 and the temperature conduction rods 120 can be made of copper.

[0044] Embodiment 4

[0045] Please see attached Figure 8-9

[0046] Specifically, an arc-shaped cooling groove 13 is provided on the inner wall of the body shell 1, the width of the arc-shaped cooling groove 13 is smaller than the width of the bearing 3, and the arc of the arc-shaped cooling groove 13 is less than 300°; a liquid inlet through hole 14 and a liquid outlet through hole 15 are provided on the side wall of the arc-shaped cooling groove 13, and a sealing ring 16 matching therewith is provided in the liquid inlet through hole 14 and the liquid outlet through hole 15.

[0047] Taking into account that the effects of indirect contact liquid cooling and air cooling are far inferior to direct contact liquid cooling, an arc-shaped cooling groove 13 is provided on the inner wall of the body shell 1, and liquid is directly poured into the body shell 1 through the liquid inlet through hole 14 and the liquid outlet through hole 15 for direct contact cooling with the bearing 3. In order to ensure that the liquid does not flow out, the liquid inlet through hole 14 and the liquid outlet through hole 15 are provided with matching sealing rings 16 for sealing. At the same time, in order to prevent the coolant in the arc-shaped cooling groove 13 from flowing into the body shell 1, the width and curvature of the arc-shaped cooling groove 13 are further restricted.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
