Description

Technical Field

[0001] This application relates to the technical field of steel ball screening, for example, to a general-purpose steel ball drum screening device. Background Art

[0002] In the production and experimental processes of magnetic materials, due to the wet grinding process in the production process, steel balls will inevitably have serious wear during long-term friction and contact with materials, and the wear degrees of steel balls are also inconsistent. When the particle size of steel balls is consumed to a certain extent, it cannot meet the production process requirements. In line with the principles of energy conservation, consumption reduction, recycling and utilization, steel balls with larger particle sizes can be recovered through screening.

[0003] Currently, the conventional practice in the production workshop is to collect all steel balls and wash them with water, and then manually put the steel balls onto a linear vibrating screen with a perforated plate. The perforated plate is vibrated by a centrifugal vibrator for screening. However, this screening method requires full manual participation, has a high labor intensity, low efficiency, and the screen holes are extremely easy to be blocked during vibration, resulting in low separation efficiency. Summary of the Utility Model

[0004] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. This summary is not a general review, nor is it intended to identify key / important constituent elements or delineate the protection scope of these embodiments, but rather serves as a preamble to the subsequent detailed description.

[0005] The embodiments of the present disclosure provide a general-purpose steel ball drum screening device with a reasonable structure, which can increase the screening efficiency of steel ball materials and reduce the manual labor intensity.

[0006] To achieve the above object, the technical solution adopted by the present utility model is:

[0007] A general-purpose steel ball drum screening device, including a main frame, a screening drum, a driving main shaft, and a driving motor. The screening drum is arranged at the top of the main frame, and the main frame is mainly used to support the screening drum. The driving main shaft is arranged inside the screening drum. A number of groups of supporting web plates are arranged on the periphery of the driving main shaft. One end of the supporting web plate is fixedly connected to the driving main shaft, and the other end is fixedly connected to the inner side wall of the screening drum, in a structure similar to that of a wheel hub spoke. The driving main shaft supports the screening drum through the supporting web plates. Both ends of the driving main shaft are mounted on the top side of the main frame by means of rotation. A driving motor is fixedly arranged on the side wall of the end of the main frame. Chain gears are provided at the output end of the driving motor and the corresponding end of the driving main shaft. The chain gears are connected to each other by a chain. The driving motor drives the driving main shaft through the cooperation of the chain gears and the chain. The driving main shaft drives the screening drum to rotate through the cooperation of the supporting web plates to achieve the purpose of screening steel balls. A number of groups of segmented spiral blades are evenly arranged inside the screening drum. After the staff imports the steel balls into the inside of one end of the screening drum through the feed hopper, during the rotation of the screening drum, the segmented spiral blades will play a guiding role on the steel balls in the screening drum, prompting the steel balls to roll towards the other end of the screening drum. An outer cover is sleeved on the top side of the screening drum to prevent dust from polluting the environment. A water guide pipe is fixedly attached to the peripheral side of the top of the outer cover. A number of spray heads passing through the protective cover are arranged inside the water guide pipe. Water is supplied to the water guide pipe by an external water pump, and the screening drum is sprayed through the spray heads to clean the steel ball material inside the screening drum. The spray heads can adopt fan-shaped high-pressure spray heads to facilitate adjusting the fan-shaped angle and water pressure to achieve the purpose of uniform cleaning. The steel balls are screened by the driving motor driving the screening drum to roll through the chain. The residence time of the steel ball material in the screening drum can be well controlled by the frequency conversion of the driving motor. The faster the driving motor drives, the greater the centrifugal force, so that the steel balls leave the screening drum faster under the action of the segmented spiral blades. Controlling the low frequency of the driving motor can make the steel ball material stay in the screening drum for a long time to facilitate thorough cleaning and achieve the effect of sufficient screening. During the rotation of the screening drum, those that cannot pass through the sieve and whose ball diameter is larger than the mesh hole will naturally be discharged from the screening drum under the action of the segmented spiral blades. During the rotation of the screening drum, the steel balls can avoid blocking the mesh holes of the screening drum under the action of rolling and centrifugal force, increasing the efficiency, and the whole process is automated, reducing manual participation and lowering the labor intensity.

[0008] Further, a feed hopper is arranged at one end of the screening drum, and the bottom end of the feed hopper extends into the screening drum. The feed hopper is convenient for adding materials into the screening drum. A discharge hopper is arranged at the bottom side of the other end of the screening drum, and the discharge hopper is fixedly connected to one side of the main frame. The screened steel ball material is discharged through the discharge hopper.

[0009] Further, a recovery hopper is fixedly arranged inside the main frame, and the recovery hopper is sleeved on the bottom side of the screening drum. The steel balls screened by the screening drum are collected through the recovery hopper.

[0010] Further, bearing supports are sleeved on both ends of the driving main shaft, and the bearing supports are arranged on the top sides of the corresponding ends of the main frame. The driving main shaft is movably supported by the bearing supports, which facilitates rotation driven by the driving motor.

[0011] Further, a fixing seat is arranged on one side of the driving motor. One end of the fixing seat is sleeved on the end of the driving motor, and the other end is fixedly connected to the side wall of the main frame. The driving motor is fixed by the fixing seat.

[0012] Further, a chain guard is sleeved outside the chain gear. The chain guard is fixed to one side of the main frame by screws. The chain connected to the chain gear is protected by the chain guard, which can not only prevent external sundries from affecting the drive, but also protect the staff and avoid injury.

[0013] Further, mesh holes are regularly and densely arranged on the circumferential side of the sieve cylinder. The aperture of the mesh holes is set according to the situation, and steel balls with diameters larger and smaller than the aperture of the mesh holes can be effectively separated.

[0014] Further, a support rod is fixedly arranged at the bottom of the feed hopper. The bottom end of the support rod is fixedly connected to the main frame. The feed hopper is fixedly supported by the support rod.

[0015] Further, heavy-duty casters are arranged at the bottoms of the legs of the main frame, which facilitates overall movement.

[0016] A general steel ball drum screening device provided by an embodiment of the present disclosure can achieve the following technical effects:

[0017] 1. In the present utility model, the driving motor drives the sieve cylinder to roll through a chain to screen the steel balls. The residence time of the steel ball material in the sieve cylinder can be well controlled by frequency conversion of the driving motor. The faster the driving motor drives, the greater the centrifugal force, and thus the steel ball material leaves the sieve cylinder faster under the action of the segmented spiral blades. Controlling the low frequency of the driving motor can make the steel ball material stay in the sieve cylinder for a sufficient time for thorough cleaning and achieving a sufficient screening effect.

[0018] 2. In the present utility model, during the rotation of the sieve cylinder, materials that cannot pass through the sieve and steel balls with diameters larger than the mesh holes will naturally be discharged from the sieve cylinder under the action of the segmented spiral blades. During the rotation of the sieve cylinder, the steel balls can avoid blocking the mesh holes of the sieve cylinder under the action of rolling and centrifugal force, improving efficiency. And the whole process is automated, reducing manual participation and labor intensity.
