Description

Technical Field

[0001] The present application relates to the technical field of ultrafine copper powder preparation, and more specifically, to a pretreatment drying method for ultrafine copper powder preparation. Background Art

[0002] As a raw material used in the industrial field, ultrafine copper powder can be dispersed in various lubricating oils in a suitable manner to form a stable suspension, becoming a lubricant with excellent performance, reducing friction between parts and protecting equipment. In the production process of ultrafine copper powder, drying equipment is often required to dry the copper powder.

[0003] Some existing drying equipment uses electric heating tubes to dry copper powder. However, since the copper powder is in an inactive state, this treatment method may easily result in the copper powder far away from the electric heating tube not being completely dried, or the copper powder can only be completely dried by extending the drying time, resulting in reduced heating effect, which needs to be improved.

[0004] In order to solve the above problems, the present application provides a pretreatment drying method for preparing ultrafine copper powder. Summary of the invention

[0005] The present application provides a pretreatment drying method for preparing ultrafine copper powder using the following technical scheme:

[0006] A pretreatment drying method for preparing ultrafine copper powder comprises a support seat, a processing tank is provided at the top of the support seat, a lifting tank is provided in the processing tank, driving tooth plates are provided on the left and right sides of the lifting tank, a driving mechanism is provided on the side away from each other of the two driving tooth plates, a locking mechanism is installed on the top of the driving tooth plates, a cover plate is provided above the lifting tank, a rotating rod is provided in the lifting tank, a plurality of toggle plates are connected to the outer wall of the rotating rod, a plurality of electric heating rods are installed on the inner wall of the lifting tank, and a buffer mechanism is installed on the top of the rear side wall of the processing tank.

[0007] Through the above technical scheme, the lifting tank is controlled to move upward by the driving mechanism, so that after the drying process of the copper powder is completed, the lifting tank can be lifted up separately and the copper powder in the lifting tank can be taken out. In the actual operation process, the lifting tank can be lifted up and the copper powder in the lifting tank can be fully moved by controlling the rotation of the lifting tank, which makes it convenient to dry the copper powder in the lifting tank by the electric heating rod.

[0008] Furthermore, the buffer mechanism includes a fixed plate, a movable slide groove is provided at the top of the fixed plate, a slider is provided in the movable slide groove, the slider is connected to the inner wall of the movable slide groove by a buffer spring, a groove is provided on the slider, and a rotating plate is rotatably installed in the groove, a bonding plate is rotatably installed on the rotating plate, and a raised shape is provided on the top of the rotating plate, and the side wall of the raised shape on the rotating plate is connected to the bonding plate by a reset spring.

[0009] Through the above technical scheme, by controlling the lifting tank to rotate for unloading, the buffer spring and the return spring can cooperate to buffer the flipping speed of the lifting tank during the flipping process, thereby preventing the lifting tank from directly tipping over due to rapid rotation of the lifting tank.

[0010] Furthermore, a U-shaped block is fixedly installed on the side wall of the slider connected to the reset spring, and the U-shaped block is located above the reset spring. A lifting limit plate is movably installed in the U-shaped groove on the U-shaped block, and the lifting limit plate is L-shaped and extends to directly above the slider. A threaded through hole is provided on the outer wall of the U-shaped block, and a locking screw is provided in the threaded through hole.

[0011] Through the above technical scheme, the position of the lifting limit plate is fixed by controlling the rotation of the locking screw, which can facilitate limiting the rotation range of the rotating plate during use to avoid excessive rotation of the rotating plate. By fixing the height of the lifting limit plate, it can be prevented that the rotating plate can move freely, causing the lifting tank to move excessively and directly hit the outer wall of the processing tank, causing the lifting tank to deform.

[0012] Furthermore, the driving mechanism includes a U-shaped frame, a movable groove is provided at the top of the U-shaped frame, a movable plate is provided in the movable groove, a driving gear is provided at the top of the movable plate, and an adjusting screw is rotatably installed on the side wall of the movable plate.

[0013] Through the above technical scheme, it is convenient to adjust the position of the driving gear by controlling the rotation of the adjusting screw, and it is convenient to disconnect the driving gear from the driving tooth plate by adjusting the movement of the screw when controlling the rotation of the lifting tank, so as to avoid the driving tooth plate and the driving gear being in a contact state, resulting in the processing tank being unable to rotate around the plug-in rod.

[0014] Furthermore, a through hole is provided on the side wall of the U-shaped groove on the U-shaped frame, and a plug-in rod is movably installed in the through hole.

[0015] The above technical solution ensures that the lifting tank can rotate around the two plug-in rods.

[0016] Furthermore, the locking mechanism includes a column, a top end of the column is provided with a groove, a rotating rod is rotatably installed in the groove, a pressure plate is fixedly installed on the outer wall of the rotating rod, and a clamping block is fixedly installed on the outer wall of the pressure plate.

[0017] Through the above technical solution, it is convenient to fix the cover plate on the top of the lifting tank for use, and it is convenient to open the opening at the top of the lifting tank later to take out the copper powder therein.

[0018] Furthermore, a slot is provided at the top of the rotating rod, a rotating motor is installed on the cover plate, and a toggle block matching the shape and size of the slot is fixedly installed at the bottom end of the rotating motor.

[0019] Through the above technical solution, during use, the rotating motor drives the rotating rod to rotate, so as to fully stir the copper powder in the processing tank.

[0020] Furthermore, a plug-in rotating hole is provided on one side of the two driving tooth plates which are away from each other, and the diameter of the plug-in rotating hole is the same as the diameter of the rotating rod.

[0021] The above technical solution can facilitate the rotation of the lifting tank.

[0022] Furthermore, two plug-in card slots are provided at the top of the cover plate, and the length, width and height dimensions of the plug-in card slots are the same as those of the card block.

[0023] Through the above technical solution, it is convenient to connect the card block and the cover plate into a whole.

[0024] In summary, this application includes the following beneficial technical effects:

[0025] (1) When the copper powder in the lifting tank is heated and dried, the rotating motor can be used to drive the rotating rod and the toggle plate to rotate, so as to toggle the copper powder in the lifting tank and dry the copper powder through the electric heating rod, so as to avoid the copper powder far away from the electric heating tube from being not completely dried due to the copper powder being in an inactive state.

[0026] (2) By controlling the rotation of the adjusting screw, the contact between the driving gear and the driving tooth plate is disconnected, and the plug rod is inserted into the plug-in rotating hole on the driving tooth plate, the lifting tank can be manually pushed to rotate around the two plug rods, so that the copper powder can be moved to avoid the inability to effectively dry it by the electric heating rod.

[0027] (3) During the rotation of the lifting tank, the lifting tank will contact the bonding plate. After the bonding plate is unloaded by the return spring and the buffer spring, the lifting tank is prevented from rotating too much and at too high a speed, causing the lifting tank to collide with the processing tank.
