Description

Technical Field

[0001] The utility model relates to the technical field of thermal conductive powder wet modification, in particular to a thermal conductive powder wet modification device. Background Art

[0002] Thermal conductive powder is a powder material with good thermal conductivity. This material is usually used in the manufacture of electronic equipment, electrical products, radiators and other equipment to improve their heat dissipation efficiency and reduce operating temperature. Thermal conductive powder wet modification is a technology used to improve the performance of thermal conductive powder. It involves mixing thermal conductive powder with specific chemicals or additives and treating it through a wet process to change the surface properties of the powder and improve its thermal conductivity and other related physical properties.

[0003] As disclosed in Chinese patent CN209918254U, a device for wet modification and screening of thermal conductive powder includes a stirring tank, a filter tower, a dryer and a screening rack, wherein a first transport pipe is connected to a side pipeline of the stirring tank, and a first booster pump is electrically connected to the interior of the first transport pipe, and the other end of the first transport pipe is connected to the filter tower by a pipeline, a plurality of filter layers are arranged inside the filter tower, and a filter screen is arranged in the middle of the filter; a second transport pipe is connected to the side bottom end of the filter tower, and a second booster pump is electrically connected to the interior of the second transport pipe, and the other end of the second transport pipe is connected to the dryer by a pipeline, a powder extractor is electrically connected to the side bottom end of the dryer, and a third transport pipe is connected to the upper pipeline of the powder extractor, and the other end of the third transport pipe is connected to the screening rack by a pipeline, a first sieve is arranged at the top of the screening rack, a second sieve is arranged in the middle of the screening rack, and a third sieve is arranged at the bottom of the screening rack.

[0004] Although this structure can be used to wet-modify the thermally conductive powder, when it is mixed in a stirring tank, the position of the stirring column inside the stirring tank is fixed, which limits the mixing range of the thermally conductive powder. Therefore, we propose a thermally conductive powder wet-modification device that can expand the mixing range of the thermally conductive powder to improve the mixing effect of the thermally conductive powder. Utility Model Content

[0005] The utility model aims to provide a device for wet modification of heat-conducting powder to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for wet modification of thermally conductive powders, comprising a stirring tank, a transport pipe is connected to the outer wall of the stirring tank, a filter tank is connected to one end of the transport pipe away from the stirring tank, a drying tank is provided on the side of the filter tank away from the stirring tank, a screening tank is provided on the side of the drying tank away from the filter tank, and a processing component is arranged inside the stirring tank, the processing component includes a mixing component arranged inside the stirring tank, and a vibration component is arranged outside the mixing component.

[0007] Preferably, the mixing assembly includes a cross plate arranged inside the mixing tank, a limiting groove is provided inside the cross plate, a tooth plate is fixedly installed on the inner wall of the limiting groove, a sleeve groove is provided on the side wall of the limiting groove, a baffle is slidably provided inside the sleeve groove, a stirring rod is rotatably connected inside the baffle, a gear is fixedly installed on the end of the stirring rod, a first spring is fixedly installed on the end of the baffle, and a rotating rod is fixedly installed at the center of the cross plate.

[0008] Preferably, the vibration assembly includes a mounting plate fixedly mounted on the top surface of the outer wall of the stirring tank, a motor is fixedly mounted on the outer wall of the mounting plate, a sleeve is fixedly mounted on the output end of the motor, a second spring is fixedly mounted on the inner wall of the sleeve, a slider is fixedly mounted on one end of the second spring away from the inner wall of the sleeve, a rotating column is fixedly mounted on the side of the slider away from the second spring, and a wedge rod is fixedly mounted on the inner bottom surface of the stirring tank.

[0009] Preferably, one end of the first spring is fixedly installed on an end of the baffle away from the rotating rod, and the other end of the first spring away from the baffle is fixedly installed on the inner wall of the sleeve groove. Under the action of the elasticity of the first spring, the stirring rod affected by the centrifugal force is pushed toward the rotating rod, and the stirring rod can rotate forward and reverse reciprocatingly.

[0010] Preferably, the side of the stirring rod away from the stirring rod is slidably arranged with the inner wall of the limiting groove, and the gear is meshed with the tooth plate. When the stirring rod is subjected to centrifugal force, the gear is meshed with the tooth plate, so that the stirring rod can rotate.

[0011] Preferably, the outer wall of the wedge-shaped rod is arranged in an inclined surface, and the wedge-shaped rod is arranged in contact with the inclined surface of the rotating rod away from the motor. When the rotating rod is in contact and squeezed with the inclined surface of the wedge-shaped rod, it tends to move upward, driving the cross plate and the stirring rod upward, so that the stirring rod expands the stirring range, and at the same time avoids the thermal conductive powder from adhering to the outer wall of the stirring rod.

[0012] Preferably, the outer wall of the slider is arranged in a multi-tooth shape, and the outer wall of the slider is slidably arranged with the inner wall of the sleeve. Under the restriction of the outer wall, the rotating sleeve can drive the slider to rotate accordingly, and the slider can slide and rotate inside the sleeve.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The thermally conductive powder wet modification device is composed of a mixing component as one of its components. When the thermally conductive powder needs to be mixed, it is added into the stirring tank, and the motor is started to rotate the cross plate, which drives the rotating rod to rotate accordingly. Since the outer wall of the stirring rod is connected to the outer wall of the baffle plate and the sleeve groove provided on the side wall of the limiting groove are slidably arranged, and the gear fixedly installed at the end of the stirring rod is meshed with the toothed plate fixedly installed on the inner wall of the limiting groove, under the action of centrifugal force, the stirring rod is swung away from the rotating rod, so that the gear fixedly installed at the end of the stirring rod is meshed with the toothed plate, and the gear starts to rotate, so as to drive the stirring rod to rotate, and the rotating stirring rod mixes the thermally conductive powder, and at the same time The rotating rotating rod drives the stirring rod to rotate with the center of the rotating rod as the rotation center, so that the stirring rod can rotate at the same time as it rotates, so as to expand the stirring range of the thermal conductive powder. When the baffle slides in the direction of the first spring, the first spring is compressed. Under the action of the elasticity of the first spring, the baffle is pushed in the direction of the rotating rod, and the stirring rod can rotate forward and reverse reciprocatingly to fully stir the thermal conductive powder inside the stirring tank. Under the restriction of the baffle, the thermal conductive powder can be prevented from entering the limit groove and affecting the meshing of the gear and the tooth plate (the stirring tank, filtering tank, drying tank, screening tank and transport pipe are existing public technologies in the comparative documents, so their structures are not fully described in this case).

[0015] 2. The thermal conductive powder wet modification device is composed of a vibration component as one of its components. When the thermal conductive powder in the stirring tank needs to be mixed, the motor is started, and the sleeve fixedly installed at the output end thereof rotates accordingly. Since the outer wall of the slider and the inner wall of the sleeve are both provided with multiple teeth, the slider slidingly arranged inside the sleeve rotates accordingly, and the slider drives the rotating column to rotate, and the rotating column drives the cross plate fixedly installed at one end away from the slider to rotate, and the cross plate drives the rotating rod to rotate. Since the end of the rotating rod away from the motor is provided with an inclined surface, and the inclined surface of the rotating rod and the inclined surface of the wedge rod are aligned with each other, the rotating rod is provided with an inclined surface. When the rotating rod rotates, its inclined surface contacts and squeezes the inclined surface of the wedge-shaped rod, causing the rotating rod to move upward, and the rotating rod pushes the cross plate upward, so that the rotating column fixedly installed on the top surface of the cross plate drives the slider to slide into the inside of the sleeve, and the slider squeezes the second spring. When the rotating rod and the wedge-shaped rod are no longer squeezed by the inclined surface, the rotating rod is pushed downward under the action of the rotating rod's own gravity and the elasticity of the second spring, and the reciprocating stirring rod produces a vibrating effect. The stirring rod moving up and down can expand the mixing range and prevent the thermal conductive powder from adhering to the outer wall of the stirring rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0024] Example 1

[0025] A preferred embodiment of the thermal conductive powder wet modification device provided by the utility model is as follows: Figures 1 to 6 As shown: a thermally conductive powder wet modification device, comprising a stirring tank 1;

[0026] The outer wall of the stirring tank 1 is connected to a transport pipe 5;

[0027] One end of the transport pipe 5 away from the stirring tank 1 is connected to the filter tank 2;

[0028] A drying tank 3 is provided on one side of the filter tank 2 away from the stirring tank 1;

[0029] A screening tank 4 is provided on one side of the drying tank 3 away from the filtering tank 2;

[0030] And a processing component 6 is arranged inside the stirring tank 1, the processing component 6 includes a mixing component 61 arranged inside the stirring tank 1, the mixing component 61 includes a cross plate 611 arranged inside the stirring tank 1, a limiting groove 612 is opened inside the cross plate 611, a tooth plate 613 is fixedly installed on the inner wall of the limiting groove 612, a sleeve groove 614 is opened on the side wall of the limiting groove 612, a baffle 617 is slidably arranged inside the sleeve groove 614, a stirring rod 616 is rotatably connected inside the baffle 617, a gear 615 is fixedly installed on the end of the stirring rod 616, a first spring 618 is fixedly installed on the end of the baffle 617, and a rotating rod 619 is fixedly installed at the center of the cross plate 611.

[0031] In this embodiment, when the thermal conductive powder needs to be mixed, it is added into the mixing tank 1, and the motor 622 is started to rotate the cross plate 611, and the cross plate 611 drives the rotating rod 619 to rotate accordingly. Since the outer wall of the baffle 617 connected to the outer wall of the stirring rod 616 is rotatably arranged with the sleeve groove 614 opened on the side wall of the limiting groove 612, and the gear 615 fixedly installed at the end of the stirring rod 616 is meshed with the tooth plate 613 fixedly installed on the inner wall of the limiting groove 612, under the action of centrifugal force, the stirring rod 616 is swung away from the rotating rod 619, so that the gear 615 fixedly installed at the end of the stirring rod 616 is meshed with the tooth plate 613, so that the gear 615 starts to rotate, so as to drive the stirring rod 616 to rotate, and the rotating stirring rod 616 mixes the thermal conductive powder, and at the same time, the rotating rotating rod 619 drives the stirring rod 616 to rotate with the center of the rotating rod 619 as the rotation center, so that the stirring rod 616 can rotate while it rotates to expand the stirring range of the thermally conductive powder. When the baffle 617 slides in the direction of the first spring 618, the first spring 618 is compressed. Under the elastic action of the first spring 618, the baffle 617 is pushed in the direction of the rotating rod 619, and the stirring rod 616 can rotate forward and reverse reciprocatingly to fully stir the thermally conductive powder inside the stirring tank 1. Under the restriction of the baffle 617, the thermally conductive powder can be prevented from entering the limiting groove 612 and affecting the meshing of the gear 615 and the tooth plate 613 (the stirring tank 1, the filtering tank 2, the drying tank 3, the screening tank 4 and the transport pipe 5 are existing public technologies in the comparative documents, so their structures are not fully described in this case).

[0032] Furthermore, one end of the first spring 618 is fixedly installed with one end of the baffle 617 away from the rotating rod 619, and one end of the first spring 618 away from the baffle 617 is fixedly installed with the inner wall of the sleeve groove 614. Under the elastic action of the first spring 618, the stirring rod 616 affected by the centrifugal force is pushed toward the rotating rod 619, and the stirring rod 616 can rotate forward and reverse reciprocatingly.

[0033] Furthermore, the side of the stirring rod 616 away from the stirring rod 616 is slidably arranged with the inner wall of the limiting groove 612, and the gear 615 is meshed with the tooth plate 613. When the stirring rod 616 is subjected to the centrifugal force, the gear 615 is meshed with the tooth plate 613, so that the stirring rod 616 can rotate.

[0034] Example 2

[0035] Based on Example 1, a preferred embodiment of a thermally conductive powder wet modification device provided by the present invention is as follows: Figures 1 to 6 As shown: the vibration assembly 62 includes a mounting plate 621 fixedly mounted on the top surface of the outer wall of the mixing tank 1, a motor 622 is fixedly mounted on the outer wall of the mounting plate 621, a sleeve 623 is fixedly mounted on the output end of the motor 622, a second spring 625 is fixedly mounted on the inner wall of the sleeve 623, a slider 624 is fixedly mounted on the end of the second spring 625 away from the inner wall of the sleeve 623, a rotating column 626 is fixedly mounted on the side of the slider 624 away from the second spring 625, and a wedge rod 627 is fixedly mounted on the inner bottom surface of the mixing tank 1.

[0036] In this embodiment, when it is necessary to mix the heat-conducting powder inside the stirring tank 1, the motor 622 is started, and the sleeve 623 fixedly installed at its output end rotates accordingly. Since the outer wall of the slider 624 and the inner wall of the sleeve 623 are both multi-toothed, the slider 624 slidingly set inside the sleeve 623 rotates accordingly, and the slider 624 drives the rotating column 626 to rotate, and the rotating column 626 drives the cross plate 611 fixedly installed at one end away from the slider 624 to rotate, and the cross plate 611 drives the rotating rod 619 to rotate. Since the end of the rotating rod 619 away from the motor 622 is arranged at an inclined surface, and the inclined surface of the rotating rod 619 contacts the inclined surface of the wedge rod 627, when the rotating rod 619 rotates , its inclined surface contacts and squeezes the inclined surface of the wedge-shaped rod 627, so that the rotating rod 619 moves upward, and the rotating rod 619 pushes the cross plate 611 upward, so that the rotating column 626 fixedly installed on the top surface of the cross plate 611 drives the slider 624 to slide into the sleeve 623, and the slider 624 squeezes the second spring 625. When the rotating rod 619 and the wedge-shaped rod 627 are no longer squeezed by the inclined surface, the rotating rod 619 is pushed downward under the action of its own gravity and the elasticity of the second spring 625, and the reciprocating stirring rod 616 produces a vibration effect. The stirring rod 616 moving up and down can expand the mixing range and prevent the thermal conductive powder from adhering to the outer wall of the stirring rod 616.

[0037] Furthermore, the outer wall of the wedge rod 627 is arranged to be inclined, and the wedge rod 627 is arranged to be in contact with the inclined surface of the rotating rod 619 at one end away from the motor 622. When the rotating rod 619 is in contact and squeezed with the inclined surface of the wedge rod 627, it tends to move upward, driving the cross plate 611 and the stirring rod 616 upward, so that the stirring rod 616 expands the stirring range, and at the same time prevents the thermal conductive powder from adhering to the outer wall of the stirring rod 616.

[0038] In addition, the outer wall of the slider 624 is configured in a multi-toothed shape, and the outer wall of the slider 624 is slidably configured with the inner wall of the sleeve 623 . Under the restriction, the rotating sleeve 623 can drive the slider 624 to rotate accordingly, and the slider 624 can slide and rotate inside the sleeve 623 .

[0039] The above is only an illustrative specific implementation method of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model. It should also be noted that the various components of the utility model are not limited to the above-mentioned overall application. The various technical features described in the specification of the utility model can be selected one by one or multiple ones can be selected and used in combination according to actual needs. Therefore, the utility model should naturally cover other combinations and specific applications related to the utility model points of this case.
