Description

Technical Field

[0001] This utility model relates to the field of covering agent screening, and in particular to a vibrating screen for covering agent production. Background Technology

[0002] Covering agent is a material used in casting production to cover the surface of molten metal in risers to prolong the solidification time. There are two types of covering agents: heat-insulating covering agents and heat-generating covering agents. However, currently, the production process of covering agents usually requires the use of vibrating screens for screening.

[0003] However, the current vibrating screen has a simple screening structure, resulting in poor screening effect and low efficiency for the covering agent. During screening, the covering agent needs to be screened separately. First, the covering agent is screened for the first time to remove larger particles or lumps. Then, the removed lumps and particles are crushed and screened a second time to obtain all the screened covering agent. The above process is relatively cumbersome and inefficient. Utility Model Content

[0004] One objective of this invention is to provide a vibrating screen for producing a covering agent that at least solves one of the aforementioned technical problems.

[0005] A further objective of this invention is to avoid multiple screenings and save screening time.

[0006] Another further objective of this invention is to improve screening efficiency.

[0007] In particular, this utility model provides a vibrating screen for producing a covering agent, including a feeding mechanism, which includes a first feeding pipe, a second feeding pipe and a third feeding pipe, which are arranged coaxially from top to bottom.

[0008] The two barrier plates are arranged vertically at intervals, and a portion of the barrier plate passes through the gap formed between the openings of the first feed pipe, the second feed pipe and the third feed pipe.

[0009] A protective cover is disposed below the barrier plate;

[0010] A rotating shaft, the upper end of which is fixedly connected to the barrier disk, and a crushing disk is provided on the rotating shaft, the crushing disk being located below the protective cover;

[0011] A vibration mechanism, comprising a filter disc located below the crushing disc and sleeved on the rod of the rotating shaft.

[0012] Furthermore, it also includes a fixing plate, which has fixing holes and a fixing rod on the lower edge of the fixing plate, the fixing rod being fixedly connected to the protective cover;

[0013] The first feeding pipe is installed in the fixing hole, the second feeding pipe is connected to the fixing rod through a connecting rod, and the third feeding pipe is connected to the protective cover.

[0014] Furthermore, the vibration mechanism includes: an outer cylinder disposed at the lower part of the filter disc, a spring disposed inside the outer cylinder, an inner cylinder disposed below the spring, a sliding groove disposed on the inner side of the outer cylinder, and a sliding strip disposed on the outer side of the inner cylinder, the sliding strip moving within the sliding groove;

[0015] A limit ring is provided on the upper part of the rotating shaft, a first protrusion is provided on the lower part of the limit ring, and a second protrusion is provided on the side of the filter disc facing the limit ring.

[0016] Furthermore, a collection plate is provided below the filter disc.

[0017] Furthermore, a preset distance is provided between the protective cover and the crushing disc.

[0018] Furthermore, both the protective cover and the crushing disc adopt an umbrella-shaped structure.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] This invention features a barrier disc on a rotating shaft that allows the covering agent to fall intermittently. The rotating shaft drives the barrier disc to rotate, and the cooperation of the first, second, and third feeding pipes feeds the covering agent between a grinding disc and a protective cover. The rotating shaft drives the grinding disc to rotate, thus grinding small pieces of the covering agent. The agent slides down the inclined surface of the grinding disc onto a filter disc. The filter disc rotates via the rotating shaft, driving a limiting ring to rotate. The lower part of the limiting ring has a first protrusion. The first protrusion collides with a second protrusion on the filter disc, causing the filter disc to vibrate, thereby sieving the covering agent. Finally, the agent falls onto a collection plate for collection, achieving a multi-functional effect with a single shaft, thus avoiding multiple sieving processes and saving sieving time.

The rotating shaft 5 is driven by a stepper motor. A protective cover 6 is positioned below the barrier plate 4. The upper end of the rotating shaft 5 is fixedly connected to the barrier plate 4, and the rotating shaft 5 is equipped with... A crushing disc 9 is located below the protective cover 6. A covering agent is fed between the crushing disc 9 and the protective cover 6 through a third feeding pipe 14.

[0032] The upper part of the rotating shaft 5 is provided with a limiting ring 16, and the lower part of the limiting ring 16 is provided with a first protrusion 17. The side of the filter disk 7 facing the limiting ring 16 is provided with a second protrusion 18. The rotating shaft 5 drives the first protrusion 17 on the limiting ring 16 to rotate, thereby contacting the second protrusion 18 and forming a vertical displacement, thereby achieving a vibration effect.

[0033] It should be further explained that the present invention also includes a fixing plate 1, on which a fixing hole is provided.

The lower part of the limiting ring 16 is provided with a first protrusion 17. The first protrusion 17 collides with the second protrusion 18 provided on the filter disc 7, thereby causing the filter disc 7 to vibrate, thus screening the covering agent. Finally, the material falls onto the collection plate 8 for collection, achieving the effect of multiple functions on one shaft, thereby avoiding multiple screenings and saving screening time.
