Description

Technical Field

[0001] The utility model belongs to the technical field of diamond micropowder manufacturing, and in particular relates to a diamond micropowder pickling device. Background Art

[0002] In the production process, diamond powder generally needs to go through four process steps: diamond crushing → diamond powder pickling → diamond powder water washing → diamond powder sorting; in the pickling process, in order to improve the pickling effect and efficiency, the acid solution and diamond powder mixture in the container are usually heated. In the prior art, when pickling diamond powder, the diamond powder is generally poured into the pickling barrel filled with acid solution for pickling, and the diamond powder is stirred with a stirring paddle, but it takes a long time to stir the diamond powder and the acid solution. At the same time, it takes a long time to fully heat the acid solution and diamond powder mixture poured into the pickling barrel at one time. The unevenly heated diamond powder is easy to adhere to the inner wall of the pickling barrel, which causes insufficient heating of the internal acid solution, resulting in poor pickling effect of the diamond powder. Utility Model Content

[0003] In view of the above problems, the purpose of the present utility model is to provide a diamond powder pickling device to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the utility model adopts the following technical solution: a pickling device for diamond micropowder, comprising a pickling barrel, a heating chamber opened in the inner cavity of the pickling barrel and a heating plate arranged inside the heating chamber, a feeding pipe is arranged on the top of the pickling barrel, a hopper with a discharge port opened in the middle is arranged on the top of the feeding pipe, fixing rods are symmetrically arranged at the bottom of the hopper and on both sides of the discharge port, electric push rods are arranged on one side of the two fixing rods close to the discharge port, a baffle for sealing the discharge port is connected to the tail end of the electric push rod, an annular infusion tube is arranged at the top of the pickling barrel and on the outer periphery of the feeding tube, and a plurality of nozzles for spraying acid are evenly arranged at the bottom of the infusion tube.

[0005] The beneficial effects of the utility model are as follows: when pickling diamond micropowder, the diamond micropowder is quantitatively put into the pickling cylinder, and along with the input of the diamond micropowder, the nozzle sprays acid liquid into the pickling cylinder, and the acid liquid falls into the pickling cylinder together with the diamond micropowder, and then the acid liquid and the diamond micropowder are mixed under the action of the stirring paddle, which can accelerate the speed of uniform mixing and uniform heating of the acid liquid and the diamond micropowder, and improve the pickling effect of the diamond micropowder.

[0006] In order to contact the diamond powder with the acid solution during the process of being put into the pickling cylinder:

[0007] As a further improvement of the above technical solution: the installation angle of the nozzle is inclined from top to bottom toward the side close to the feed pipe.

[0008] The beneficial effect of this improvement is that in the process of the diamond micro-powder falling into the pickling barrel along the feeding port, the acid liquid sprayed by the nozzle can be sprayed on the diamond micro-powder first and then fall into the pickling barrel together.

[0009] To avoid diamond powder residue on the baffle:

[0010] As a further improvement of the above technical solution: a sloped notch is provided on the top of the baffle and on one side close to the feed opening.

[0011] The beneficial effect of this improvement is that when the baffle seals the feed opening, the diamond powder accumulates in the gap on the baffle, and as the baffle moves, the diamond powder on the baffle can slide along the sloped gap into the pickling cylinder to prevent the diamond powder from remaining on the baffle.

[0012] In order to mix the diamond powder and acid liquid that fall into the pickling cylinder:

[0013] As a further improvement of the above technical solution: the inner side of the feed pipe is connected to a motor through a support rod, a protective cover is provided on the top of the motor, a rotating rod is installed on the output shaft of the motor, and a plurality of stirring paddles are evenly installed on the outer wall of the rotating rod.

[0014] The beneficial effect of this improvement is that when the diamond micropowder and the acid solution fall into the pickling barrel together, the motor drives the rotating rod and the stirring paddle to rotate, so that the diamond micropowder and the acid solution can be mixed.

[0015] In order to speed up the mixing of diamond powder and acid solution and improve the effect of diamond powder pickling:

[0016] As a further improvement of the above technical solution: the cross section of the bottom of the stirring paddle is arc-shaped.

[0017] The beneficial effect of this improvement is that by providing an arc-shaped stirring paddle, the diamond powder can be driven to turn over during the rotation of the stirring paddle, thereby accelerating the mixing speed of the diamond powder and the acid solution and improving the effect of the diamond powder pickling.

[0018] In order to protect the motor and avoid the accumulation of diamond powder on the protective cover:

[0019] As a further improvement of the above technical solution: the protective cover is configured to be conical, and the size of its bottom wall is larger than the size of the motor.

[0020] The beneficial effect of this improvement is that by providing a conical protective cover, not only the motor can be protected, but also diamond powder can be prevented from accumulating on the protective cover.

[0022] As a further improvement of the above technical solution: two sliding rods are symmetrically arranged between the two fixed rods, and the bottom of the baffle is provided with a supporting plate slidably connected to the sliding rod.

[0023] The beneficial effect of this improvement is that when the electric push rod drives the baffle to move, the baffle drives the support plate to slide along the slide rod, which can improve the stability of the baffle.

[0024] In order to facilitate the discharge of acid and diamond powder from the pickling cylinder:

[0025] As a further improvement of the above technical solution: a drain pipe is arranged on one side of the bottom of the pickling barrel, a filter screen is arranged inside the drain pipe, and a discharge pipe with a sealing cap is arranged at the bottom of the pickling barrel.

[0026] The beneficial effect of this improvement is: after the diamond micropowder is pickled, the valve on the drain pipe is opened to allow the acid to be discharged along the drain pipe, and the filter can prevent the diamond micropowder from being discharged. After the acid is discharged, the sealing cap is opened to allow the diamond micropowder to be discharged along the discharge pipe. BRIEF DESCRIPTION OF THE DRAWINGS
