Description

Technical Field

[0001] The utility model belongs to the technical field of screening devices, in particular to an impurity screening device for the production of stainless steel castings. Background Art

[0002] Stainless steel castings are parts or components made of various stainless steel materials through casting processes such as melting, pouring and cooling. They are widely used and are commonly used in many fields such as aviation, automobile manufacturing and construction.

[0003] In the production process of stainless steel castings, pretreatment of raw materials is an important step. Some raw materials for stainless steel castings exist in the form of powder. In order to ensure the uniform particle size of the powder and improve the stability of the subsequent processing and product quality, most of the impurities and oversized particles in the powder are screened out through screening devices.

[0004] There are many types of screening devices on the market, such as vibrating screens and reciprocating screens. All of them screen the powder by putting the raw materials onto the screen and vibrating or reciprocating the screen. However, as the screening work continues, more impurities will gradually accumulate on the surface of the screen. At this time, when the raw materials continue to be put in, the impurities on the surface of the screen will block the screen holes, reducing the screening efficiency and causing ineffective screening.

[0007] Preferably, support rods are fixed to both side edges of the sieve plate, and a cleaning rack is elastically and slidably connected to the support rods via a second spring; the cleaning end of the cleaning rack is in contact with the surface of the sieve plate.

[0008] Preferably, one end of the sieve plate is fixedly connected to a support frame, and the interior of the support frame is slidably connected to a second baffle; the support frame passes through the interior of the bottom plate, and the second baffle slides through the interior of the bottom plate.

[0009] Preferably, a plurality of groups of clamping blocks are fixedly connected to one end of the second baffle, and the clamping blocks are positioned opposite to the cleaning rack; and magnetic plates that attract each other are correspondingly provided on one side of the clamping blocks and the cleaning rack.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model provides an impurity screening device for stainless steel casting production. When the screen plate drops due to blockage, its weight change is transmitted to the gear through the connecting block and the rack, and the linear motion is converted into the rotational motion of the gear through the meshing relationship between the rack and the gear. Then, the rotational motion is further transmitted to the screw through the transmission of the belt group and the bevel gear group. At this time, the screw rotates to drive the slider in the screw nut pair to move along its axial direction, thereby driving the first baffle to block the end of the discharge box. At the same time, the slide slides on the slide rod and compresses the first spring to timely block the discharge channel, so that the load pressure faced by the screen plate is reduced, so that the screen plate can more efficiently process the accumulated materials and separate the impurities and unqualified particles in the materials, so as to reduce the ineffective screening and damage to the screen plate caused by continuous feeding of materials. When the screening is completed or the impurities on the surface of the screen plate are cleared and restored to normal, the weight of the screen plate changes accordingly. At this time, the first spring pushes the slide and the rack to reset, and the first baffle is also removed, allowing the raw materials to continue to be fed, reducing the risk of equipment failure and production interruption caused by blockage and improving production safety.

[0015] 2. The utility model provides an impurity screening device for the production of stainless steel castings. By pulling the cleaning frame, the impurities accumulated on the surface of the screen plate can be quickly pushed to the other end for centralized collection. By loosening the cleaning frame, the screen plate automatically resets under the action of the second spring reset force. BRIEF DESCRIPTION OF THE DRAWINGS
