Description

Technical Field

[0001] The invention relates to the technical field of concrete vibrators, in particular to a cooling type vibrator. Background Art

[0002] Attached vibrators, also known as flat plate vibrators or surface vibrators, are widely used in the compaction of concrete or soil in construction projects, such as the surface compaction of concrete foundation surface and general concrete components. When the existing attached vibrators are in operation, the stator winding is energized to generate a driving magnetic field with the rotor assembly to drive the rotor shaft to rotate, and then drive the eccentric assembly to rotate to generate vibration.

[0003] When the vibrator is running at high frequency and vibrating, the temperature of the stator winding will rise excessively after a certain period of use, and the machine must be shut down for cooling, which affects production. The service life of the stator winding is short, and it needs to be repaired and replaced frequently, which causes trouble, increases costs, and reduces efficiency. Although there are some vibrators with cooling functions on the market, they all have an additional cooling circulation device. When in use, the cooling circulation device is connected to the vibrator, which increases the number of devices and requires additional assembly and disassembly steps during use, which is very inconvenient. In addition, the cooling circulation device requires an additional power source, which increases the manufacturing cost and has a poor cooling effect. Summary of the invention

[0004] The object of the present invention is to provide a cooling vibrator to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] The present invention provides a cooling vibrator, comprising:

[0007] A casing, the casing comprising a cylinder, a first end cover and a second end cover respectively arranged at two ends of the cylinder, so as to form a vibration cavity inside the casing;

[0008] A vibration system, comprising a stator assembly, a rotor assembly and an eccentric assembly, wherein the stator assembly comprises a stator winding fixed on the inner peripheral wall of the cylinder, the rotor assembly comprises a rotor shaft penetrating the stator assembly, and a rotor winding fixedly sleeved on the outer periphery of the rotor shaft, the rotor shaft is rotatably mounted in the vibration cavity, and the eccentric assembly is mounted on the rotor shaft;

[0009] A cooling system includes a power pump assembly, a heat dissipation assembly, and a cooling circulation loop. The cooling circulation loop includes a pump cavity, a heat dissipation cavity, at least one first cooling channel and at least one second cooling channel. The first cooling channel and the second cooling channel are arranged on the cylinder wall of the cylinder. The pump cavity is arranged on the first end cover, and the heat dissipation cavity is arranged on the second end cover. The pump cavity is provided with a pump inlet connected to the first cooling channel and a pump outlet connected to the second cooling channel. The heat dissipation cavity is provided with a heat dissipation inlet connected to the second cooling channel and a heat dissipation outlet connected to the first cooling channel. The cooling circulation loop is filled with coolant. The power pump assembly includes a water wheel arranged in the pump cavity, and the water wheel is drivingly connected to the rotor shaft. The heat dissipation assembly includes a heat dissipation wind wheel, and the heat dissipation wind wheel is used to dissipate heat from the heat dissipation cavity, and the heat dissipation wind wheel is drivingly connected to the rotor shaft.

[0010] The vibrator of the present invention has the following beneficial effects:

[0011] When in use, the stator winding is energized to generate a driving magnetic field with the rotor winding to drive the rotor shaft to rotate, and the rotor shaft drives the eccentric component to generate vibration. At the same time, the two ends of the rotor shaft respectively drive the water wheel and the heat dissipation wind wheel to rotate. The water wheel provides circulating power for the coolant in the cooling circulation loop, so that the coolant circulates in the cooling circulation loop, wherein the coolant circulates along the pump cavity, the second cooling channel, the heat dissipation cavity and the first cooling channel in sequence. When the coolant flows through the first cooling channel and the second cooling channel, heat is exchanged with the stator winding through the cylinder. The heat generated by the operation of the stator winding is transferred to the coolant in the first cooling channel and the second cooling channel. When the high-temperature coolant flows through the heat dissipation cavity, the heat dissipation cavity is dissipated by the rotating heat dissipation wind wheel to dissipate the heat of the coolant to the outside. The present invention drives the eccentric component, the water wheel and the heat dissipation wind wheel to rotate at the same time through the rotor shaft to synchronously realize the vibration of the vibrator, the driving of the coolant and the heat dissipation of the coolant. There is no need to set up an additional power source and other external equipment. It is more convenient to use and reduces the manufacturing cost.

[0012] As a further improvement of the above technical solution, the pump chamber and the vibration chamber are independently isolated and arranged, and a first magnetic coupling mechanism is provided between the rotor shaft and the water wheel. The first magnetic coupling mechanism includes a first magnetic disk fixed to the rotor shaft and a second magnetic disk fixed to the water wheel, and the first magnetic disk is magnetically attracted to the second magnetic disk.

[0013] In this solution, the pump chamber and the vibration chamber are isolated and independently set up, and the torque is transmitted between the rotor shaft and the water wheel through the first magnetic coupling mechanism, so that the rotor shaft can drive the water wheel to rotate together. This can avoid direct connection between the rotor shaft and the water wheel, which will cause liquid seepage between the pump chamber and the vibration chamber, thereby increasing the service life of the vibrator and reducing failures. Because high-frequency vibrations are generated during the operation of the vibrator, this places high demands on the rotating seal. Therefore, this solution solves the sealing problem through the first magnetic coupling mechanism. When in use, the first magnetic disk and the second magnetic disk are magnetically attracted to each other, the rotor shaft drives the first magnetic disk to rotate, and the first magnetic disk drives the water wheel to rotate in the pump chamber through the second magnetic disk.

[0014] As a further improvement of the above technical solution, a plurality of first cooling channels are provided, and the plurality of first cooling channels are arranged in an annular manner and spaced apart;

[0015] The first end cover is provided with a confluence cavity which is disc-shaped and laid inside the first end cover, the pump cavity is disc-shaped and is located between the interior of the casing and the confluence cavity, the outer periphery of the confluence cavity is provided with a plurality of confluence channels which are connected one-to-one with the plurality of the first cooling channels, the pump inlet is located at the center of the pump cavity and is connected with the confluence cavity, the pump outlet is located on the outer peripheral side of the pump cavity, the pump cavity is fixed with a fixed shaft for mounting the water wheel, the fixed shaft is coaxially arranged with the pump inlet, the first end cover is provided with a return channel which is connected with the second cooling channel, and the return channel is connected with the pump outlet.

[0016] This solution takes into account that the coolant after heat dissipation in the heat dissipation cavity first passes through the first cooling channel. At this time, the heat exchange capacity of the coolant in the first cooling channel is the best. In actual operation, the stator winding is installed in the cylinder, and the heat generated by the stator winding is the largest. Therefore, multiple first cooling channels are set, and the cylinder is cooled by multiple first cooling channels to improve the cooling effect on the vibrator; when the water wheel rotates in the pump cavity, a negative pressure is formed at the pump inlet, so that a negative pressure is formed in the confluence cavity. The coolants in the multiple first cooling channels are respectively converged into the confluence cavity through the confluence channel, and are mixed in the confluence cavity, and then enter the pump cavity through the pump inlet, and then flow to the second cooling channel through the pump outlet and the return channel. The water wheel of this solution adopts a centrifugal water wheel, and the coolant is sucked in from the pump inlet and then thrown out from the pump outlet. In order to improve the liquid discharge effect, in some embodiments, the pump cavity is configured to be volute-shaped.

[0017] At the same time, the confluence cavity is disc-shaped and laid inside the first end cover, and the pump cavity is located between the interior of the casing and the confluence cavity. The inner side of the confluence cavity can exchange heat with the vibration cavity through the first end cover, while the outer side of the confluence cavity exchanges heat with the outside through the first end cover, which also has the effect of heat dissipation and cooling, so as to realize the cooling of the end side of the vibrator.

[0018] As a further improvement of the above technical solution, the second end cover is provided with a rotating cavity independently isolated from the vibration cavity, and a second magnetic coupling mechanism is provided between the rotor shaft and the heat dissipation wind wheel. The second magnetic coupling mechanism includes a third magnetic disk fixed to the rotor shaft and a fourth magnetic disk transmission connected to the heat dissipation wind wheel. The fourth magnetic disk is arranged in the rotating cavity, and the third magnetic disk is magnetically attracted to the fourth magnetic disk.

[0019] The rotor shaft realizes torque transmission with the heat dissipation wind wheel through the second magnetic coupling mechanism, and in this scheme, a rotating chamber is arranged in the second end cover, and the rotating chamber and the vibration chamber are independently arranged in isolation. The fourth magnetic disk in the second magnetic coupling mechanism is arranged in the rotating chamber, and the fourth magnetic disk is connected to the heat dissipation wind wheel in a transmission manner, so that the rotor shaft can drive the heat dissipation wind wheel to rotate together, and indirectly isolate the heat dissipation chamber from the vibration chamber, thereby increasing the service life of the vibrator and reducing failures. When in use, the third magnetic disk and the fourth magnetic disk are magnetically attracted to each other, the rotor shaft drives the third magnetic disk to rotate, and the third magnetic disk drives the heat dissipation wind wheel to rotate through the fourth magnetic disk.

[0020] As a further improvement of the above technical solution, the heat dissipation cavity is disc-shaped and is laid inside the second end cover, the outer end surface of the second end cover is evenly distributed with heat dissipation wind grooves, the heat dissipation wind wheel is located on the outer end side of the second end cover, the rotating cavity is arranged between the heat dissipation cavity and the vibration cavity, the heat dissipation wind wheel is connected to a rotating shaft rotatably connected to the second end cover, and the rotating shaft passes through the heat dissipation cavity and is coaxially fixedly connected to the fourth magnetic disk.

[0021] The heat dissipation wind wheel of the present scheme is coaxially fixedly connected with the fourth magnetic disk through a rotating shaft, and the rotating cavity is located between the heat dissipation cavity and the vibration cavity to realize the torque transmission between the heat dissipation wind wheel and the rotor shaft without affecting the heat dissipation function of the heat dissipation cavity, wherein the heat dissipation wind wheel and the heat dissipation wind slot form an air inlet gap, when the heat dissipation wind wheel rotates, external air enters from the outer periphery along multiple heat dissipation wind slots, and the air and the second end cover realize convection heat exchange to realize cooling of the heat dissipation cavity, and then the hot air is blown outward along the axial direction of the heat dissipation wind wheel. Multiple heat dissipation wind slots can also increase the area of ​​convection heat exchange to improve the cooling effect of the heat dissipation cavity; and the heat dissipation cavity is disc-shaped and laid in the second end cover, the inner side of the heat dissipation cavity can exchange heat with the vibration cavity through the second end cover, and the outer side of the heat dissipation cavity exchanges heat with the outside through the second end cover, which also has the effect of heat dissipation and cooling to realize cooling of the end side of the vibrator.

[0022] As a further improvement of the above technical solution, the heat dissipation inlet and the heat dissipation outlet are distributed on the periphery of the heat dissipation cavity.

[0023] The high-temperature coolant enters the heat dissipation cavity from the heat dissipation inlet, and then flows to the first cooling channel through the heat dissipation outlet. When the high-temperature coolant flows through the heat dissipation cavity, the heat is dissipated to the outside.

[0024] As a further improvement of the above technical solution, the heat dissipation cavity is provided with a sealing sleeve, and the rotating shaft passes through the sealing sleeve to isolate the heat dissipation cavity from the rotating shaft.

[0025] In this solution, a sealing sleeve is provided to isolate the rotating shaft from the heat dissipation cavity, thereby avoiding liquid seepage between the heat dissipation cavity and the rotating shaft and improving the sealing performance.

[0026] As a further improvement of the above technical solution, a mesh-type protective cover is sleeved on the outer end side of the second end cover, and the heat dissipation wind wheel is arranged in the protective cover.

[0027] The protective cover of the present invention is used to protect the heat dissipation fan wheel, which can prevent the heat dissipation fan wheel from contacting foreign objects and protect the user to improve safety.

[0028] As a further improvement of the above technical solution, two eccentric assemblies are provided, and the two eccentric assemblies are respectively arranged on the two end sides of the rotor winding. The eccentric assembly includes at least one eccentric block. A plurality of first axial clamping portions are evenly distributed in an annular manner on the outer circumference of the rotor shaft. The eccentric block is provided with a second axial clamping portion. The first axial clamping portion and the second axial clamping portion are axially clamped. The two side edges of the eccentric block along the circumferential direction are respectively provided with a first circumferential splicing portion and a second circumferential splicing portion that are matched and clamped with each other.

[0029] In this solution, two eccentric assemblies are respectively arranged on both sides of the rotor winding, which can make the force on the rotor shaft more uniform. The rotor shaft synchronously drives the two eccentric assemblies to rotate, and also improves the vibration effect. The eccentric assembly includes an eccentric block, which is axially clamped with the first axial clamping portion on the rotor shaft through a second axial clamping portion to achieve a detachable connection. During assembly, eccentric blocks of different weights and quantities can be selected according to actual needs. When multiple eccentric blocks are arranged, two adjacent eccentric blocks are fixed to each other through matching clamping of the first circumferential splicing portion and the second circumferential splicing portion to improve the structural strength of the eccentric assembly.

[0030] As a further improvement of the above technical solution, the rotor shaft is provided with a limiting shoulder, the eccentric assembly further comprises a locking ring threadedly connected to the rotor shaft, and the eccentric block is axially clamped between the limiting shoulder and the locking ring. When assembling the eccentric assembly, the eccentric block is pushed axially so that the second axial clamping portion is clamped with the first axial clamping portion on the rotor shaft, and one side of the eccentric block is in contact with the limiting shoulder, and then the locking ring is sleeved on the rotor shaft, and the locking ring is rotated to clamp the eccentric block between the limiting shoulder and the locking ring.

[0031] Other features and advantages of the present invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Now there are some vibrators with cooling function on the market, all of which have an additional cooling circulation device. When in use, the cooling circulation device is connected to the vibrator, which increases the number of devices and requires additional assembly and disassembly steps during use, which is very inconvenient. In addition, the cooling circulation device requires an additional power source, which increases the manufacturing cost. Therefore, the present invention proposes a cooling vibrator that can simultaneously realize vibrator vibration, coolant drive and coolant heat dissipation, without the need for additional power sources and other external equipment. It is more convenient to use and reduces the manufacturing cost.

[0052] like Figure 1 As shown, the vibrator according to the embodiment of the present invention includes a housing 100, a vibration system 200 and a cooling system.

[0053] A vibration cavity 140 for installing the vibration system 200 is disposed inside the housing 100. In this embodiment, the housing 100 is extended left and right as an example. In other embodiments, the housing 100 may extend in other directions.

[0054] like Figure 1 As shown, the housing 100 of this embodiment includes a cylinder 110, a first end cover 120 and a second end cover 130. The cylinder 110 is a cylindrical structure extending left and right. The second end cover 130 and the first end cover 120 are respectively arranged at the left end and the right end of the cylinder 110. The cylinder 110, the first end cover 120 and the second end cover 130 form the above-mentioned vibration chamber 140.

[0055] In order to facilitate inspection and maintenance, the first end cover 120 and the second end cover 130 of this embodiment are both detachably connected to the cylinder 110. In some other embodiments, the cylinder 110 may be an integral structure with the first end cover 120 and the second end cover 130.

[0056] A bracket 111 is provided at the bottom of the cylinder 110 of this embodiment, and the bracket 111 is used for installing and fixing the vibrator.

[0057] The vibration system 200 includes a stator assembly, a rotor assembly and an eccentric assembly 210. The stator assembly includes a stator winding 220, which is provided with a stator core. The stator winding 220 is fixed to the inner circumferential wall of the cylinder 110, and the rotor assembly includes a rotor shaft 230 and a rotor winding 240. The rotor shaft 230 is extended left and right and arranged in the vibration cavity 140, and the rotor shaft 230 is rotatably installed in the vibration cavity 140. The rotor shaft 230 penetrates the stator assembly left and right. The left and right ends of the rotor shaft 230 of this embodiment are rotatably connected to the second end cover 130 and the first end cover 120 respectively. In order to improve the rotation stability of the rotor shaft 230, bearing seats are respectively provided on the inner sides of the second end cover 130 and the first end cover 120, and the bearing seats are installed with rotating bearings that rotate with the rotor shaft 230.

[0058] The rotor winding 240 is fixedly sleeved on the outer circumference of the rotor shaft 230 , and the position of the rotor winding 240 corresponds to that of the stator winding 220 . When the stator winding 220 is energized, a driving magnetic field can be generated with the rotor winding 240 to drive the rotor shaft 230 to rotate.

[0059] The eccentric component 210 is installed on the rotor shaft 230. The eccentric component 210 and the stator winding 220 of this embodiment are staggered, so that the installation of the eccentric component 210 is not limited to the stator winding 220, and the magnetic field driving force between the stator winding 220 and the rotor winding 240 is also improved.

[0060] like Figure 1 and Figure 2As shown, the cooling system of the embodiment of the present invention includes a power pump assembly, a heat dissipation assembly and a cooling circulation loop 300, wherein the cooling circulation loop 300 includes a pump chamber 310, a heat dissipation chamber 320, at least one first cooling channel 330 and at least one second cooling channel 340, the first cooling channel 330 and the second cooling channel 340 are arranged on the cylinder wall of the cylinder 110, the first cooling channel 330 and the second cooling channel 340 are both extended left and right through the left and right ends of the cylinder 110, the first cooling channel 330 and the second cooling channel 340 of this embodiment are both straight channels, and in some other embodiments, the first cooling channel 330 and the second cooling channel 340 may be curved serpentine channels.

[0061] The pump chamber 310 is disposed on the first end cover 120, wherein the pump chamber 310 is provided with a pump inlet 311 and a pump outlet 312, the pump inlet 311 is connected to the right end of the first cooling channel 330, and the pump outlet 312 is connected to the right end of the second cooling channel 340, and the heat dissipation chamber 320 is disposed on the second end cover 130, and the heat dissipation chamber 320 is provided with a heat dissipation inlet 321 and a heat dissipation outlet 322, the heat dissipation inlet 321 is connected to the left end of the second cooling channel 340, and the heat dissipation outlet 322 is connected to the left end of the first cooling channel 330 to form a closed-loop cooling circulation circuit 300, and the cooling circulation circuit 300 is filled with coolant.

[0062] The power pump assembly includes a water wheel 400 disposed in the pump chamber 310 , which is transmission-connected to the rotor shaft 230 . The heat dissipation assembly includes a heat dissipation wind wheel 700 , which is used to dissipate heat from the heat dissipation chamber 320 , and the heat dissipation wind wheel 700 is transmission-connected to the rotor shaft 230 .

[0063] When in use, the stator winding 220 is energized to generate a driving magnetic field with the rotor winding 240 to drive the rotor shaft 230 to rotate, and the rotor shaft 230 drives the eccentric component 210 to generate vibration. At the same time, the two ends of the rotor shaft 230 respectively drive the water wheel 400 and the heat dissipation wind wheel 700 to rotate. The water wheel 400 provides circulation power for the coolant in the cooling circulation loop 300, so that the coolant circulates in the cooling circulation loop 300. Figure 2As shown, the coolant circulates along the pump chamber 310, the second cooling channel 340, the heat dissipation chamber 320 and the first cooling channel 330 in sequence. When the coolant flows through the first cooling channel 330 and the second cooling channel 340, heat is exchanged with the stator winding 220 through the cylinder 110. The heat generated by the operation of the stator winding 220 is transferred to the coolant in the first cooling channel 330 and the second cooling channel 340. When the high-temperature coolant flows through the heat dissipation chamber 320, the heat dissipation chamber 320 is dissipated by the rotating heat dissipation wind wheel 700 to dissipate the heat of the coolant to the outside. The present invention drives the eccentric component 210, the water wheel 400 and the heat dissipation wind wheel 700 to rotate at the same time through the rotor shaft 230 to synchronously realize the vibration of the vibrator, the driving of the coolant and the heat dissipation of the coolant. There is no need to set up an additional power source and other external equipment, which is more convenient to use and reduces the manufacturing cost.

[0064] Furthermore, the pump chamber 310 of the embodiment of the present invention is located at the first end cover 120, so that the coolant exchanges heat with the first end cover 120, and the heat dissipation chamber 320 is located at the second end cover 130, so that the coolant exchanges heat with the second end cover 130, so that the coolant in the cooling circulation loop 300 can exchange heat with the periphery and both ends of the casing 100. When the coolant flows through the heat dissipation chamber 320 and the pump chamber 310, it can also transfer heat with the vibration chamber 140 in the casing 100 to expand the heat exchange area between the coolant and the vibrator and improve the heat dissipation effect.

[0065] In operation, Figure 2 As shown, the coolant with a lower temperature coming out of the heat dissipation cavity 320 first flows through the first cooling channel 330. At this time, the coolant has the best cooling effect on the cylinder 110. Then the coolant enters the pump cavity 310 for pressurization, and then flows back to the heat dissipation cavity 320 from the second cooling channel 340. The temperature of the coolant flowing through the second cooling channel 340 is higher than the coolant flowing through the first cooling channel 330, but also lower than the temperature of the cylinder 110. At this time, the coolant flowing through the second cooling channel 340 can also exchange heat with the cylinder 110, and the temperature of the coolant flowing through the pump cavity 310 is also lower than the temperature in the vibration cavity 140, and it also has a certain heat dissipation effect, dissipating the heat in the vibration cavity 140 from the first end cover 120, and the coolant flowing through the heat dissipation cavity 320, driven by the heat dissipation wind wheel 700, dissipates the heat outward, and at this time, the heat in the vibration cavity 140 is also dissipated from the second end cover 130 to achieve comprehensive heat dissipation of the vibrator.

[0066] like Figures 1 to 3 As shown, the pump chamber 310 of this embodiment is independently and isolated from the vibration chamber 140. It can be understood that the pump chamber 310 is a closed chamber arranged in the first end cover 120, and the pump chamber 310 and the vibration chamber 140 are separated by the first cover wall 121, wherein the first cover wall 121 is a magnetic conductive component.

[0067] In order to increase the service life of the vibrator and reduce failures, in this embodiment, a first magnetic coupling mechanism 500 is provided between the rotor shaft 230 and the water wheel 400. The first magnetic coupling mechanism 500 includes a first magnetic disk 510 and a second magnetic disk 520. The first magnetic disk 510 and the second magnetic disk 520 are magnetically attracted to each other. The first magnetic disk 510 and the second magnetic disk 520 are respectively permanent magnets of opposite poles. The first magnetic disk 510 is fixed to the right end of the rotor shaft 230, and the second magnetic disk 520 is fixed to the second magnetic disk 520 of the water wheel 400. In this embodiment, the pump chamber 310 and the vibration chamber 140 are isolated and independently arranged, and the first magnetic coupling mechanism 500 is used to realize the transmission of torque between the rotor shaft 230 and the water wheel 400, so that the rotor shaft 230 can drive the water wheel 400 to rotate together, thereby avoiding the rotor shaft 230 and the water wheel 400 being directly connected, and the phenomenon of liquid seepage between the pump chamber 310 and the vibration chamber 140 can be avoided.

[0068] Because high-frequency vibrations are generated during the operation of the vibrator, which places high demands on the rotating seal, the present embodiment solves the sealing problem through the first magnetic coupling mechanism 500. When in use, the first magnetic disk 510 and the second magnetic disk 520 are magnetically attracted to each other, and the rotor shaft 230 drives the first magnetic disk 510 to rotate, and the first magnetic disk 510 drives the water wheel 400 to rotate in the pump chamber 310 through the second magnetic disk 520.

[0069] At the same time, if Figure 1 , Figure 2 and Figure 4 As shown, in the embodiment of the present invention, a second magnetic coupling mechanism 600 is provided between the rotor shaft 230 and the heat dissipation wind wheel 700, and the second magnetic coupling mechanism 600 includes a third magnetic disk 610 and a fourth magnetic disk 620, the third magnetic disk 610 and the fourth magnetic disk 620 are magnetically attracted to each other, the third magnetic disk 610 and the fourth magnetic disk 620 are respectively permanent magnets of opposite poles, the third magnetic disk 610 is fixed to the left end of the rotor shaft 230, the fourth magnetic disk 620 is transmission-connected to the heat dissipation wind wheel 700, the rotor shaft 230 realizes torque transmission with the heat dissipation wind wheel 700 through the second magnetic coupling mechanism 600, when in use, the third magnetic disk 610 and the fourth magnetic disk 620 are magnetically attracted to each other, the rotor shaft 230 drives the third magnetic disk 610 to rotate, and the third magnetic disk 610 drives the heat dissipation wind wheel 700 to rotate through the fourth magnetic disk 620.

[0070] For the installation of the fourth disk 620, Figure 4As shown, the second end cover 130 is provided with a rotating chamber 132 which is isolated from the vibration chamber 140 and is independently provided. The rotating chamber 132 is provided between the heat dissipation chamber 320 and the vibration chamber 140. The rotating chamber 132 and the vibration chamber 140 are separated by a second cover wall 131, wherein the second cover wall 131 is a magnetic conductive component. The fourth magnetic disk 620 is provided in the rotating chamber 132. The heat dissipation wind wheel 700 is connected with a rotating shaft 710 which is rotatably connected to the second end cover 130. The rotating shaft 710 passes through the heat dissipation chamber 320 and is coaxially fixedly connected with the fourth magnetic disk 620. In addition, in this embodiment, a sealing spacer 323 is provided in the heat dissipation chamber 320. The rotating shaft 710 passes through the sealing spacer 323 to isolate the heat dissipation chamber 320 from the rotating shaft 710. The sealing spacer 323 is used to isolate the rotating shaft 710 from the heat dissipation chamber 320 to avoid liquid seepage between the heat dissipation chamber 320 and the rotating shaft 710, thereby improving the sealing performance.

[0071] The embodiment of the present invention indirectly isolates the heat dissipation cavity 320 from the vibration cavity 140 , thereby increasing the service life of the vibrator and reducing failures.

[0072] Furthermore, if Figure 1 , Figure 2 and Figure 5 As shown, the heat dissipation cavity 320 is disc-shaped and is laid inside the second end cover 130. The outer end surface of the second end cover 130 is evenly distributed with a plurality of heat dissipation grooves 133, and the heat dissipation wind wheel 700 is located on the outer end side of the second end cover 130.

[0075] Among them, the heat dissipation inlet 321 and the heat dissipation outlet 322 are distributed on the periphery of the heat dissipation cavity 320. The high-temperature coolant enters the heat dissipation cavity 320 from the heat dissipation inlet 321, and then flows to the first cooling channel 330 through the heat dissipation outlet 322. When the high-temperature coolant flows through the heat dissipation cavity 320, the heat is dissipated to the outside.

Therefore, a plurality of first cooling channels 330 are provided, and the cylinder 110 is cooled by the plurality of first cooling channels 330 to improve the cooling effect on the vibrator.

The water wheel 400 of this embodiment adopts a centrifugal water wheel 400, and the coolant is sucked in from the pump inlet 311 and then thrown out from the pump outlet 312.

During assembly, the snapping of the first axial snapping portion 231 and the second axial snapping portion 212, and the snapping of the first circumferential splicing portion 213 and the second circumferential splicing portion 214 can be achieved simultaneously.
