Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mineral sand production, especially to a screening structure for mineral sand production. BACKGROUND

[0002] Zircon sand, also known as zircon sand, is an important mineral resource, which is widely used in many industries due to its unique physical and chemical properties. It is mainly used to manufacture ceramic, glass, enamel and metal zircon products. Zircon sand plays an indispensable role in modern industry. In the ceramic industry, it is used as high-quality raw material to make the finished product more solid and wear-resistant. In glass manufacturing, it helps to improve the transparency and strength of the product. In addition, zircon sand also has important applications in the production of coatings and refractory materials. In the process of zircon sand mining and processing, the use of screening equipment is crucial. These devices not only effectively remove impurities from the raw ore, preventing subsequent processing, but also accurately separate high-quality zircon sand to meet different industrial needs.

[0003] The existing zircon sand screening equipment usually uses a screen to screen zircon sand, thereby screening zircon sand of the required size, avoiding the influence of zircon sand with large particles on processing. For example, Chinese patent No. CN220444410U discloses a "mineral screening machine for mining", which drives the top bin and the bottom bin to reciprocate, allowing the ore inside the top bin to be discharged through the stone outlet, while the mineral sand enters the bottom bin through the screen hole and is discharged through the sand outlet on the bottom bin, thereby facilitating separate collection and facilitating the reuse of mineral sand.

[0004] However, in actual use, the screen angle of the screening equipment cannot be adjusted. When the angle is too large, the larger zircon sand particles are easily screened out. When the angle is too large, the zircon sand screening efficiency is low, and the filter screen is easily clogged. Utility model content

[0005] The utility model aims at solving the problems of the existing technology, such as the screen angle of the screening equipment cannot be adjusted, the larger zircon sand particles are easily screened out, the zircon sand screening efficiency is low, and the filter screen is easily clogged, and proposes a screening structure for mineral sand production.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The utility model designs a kind of screening structure for ore sand production, including support, the support is provided with collection frame, the collection frame is connected with screening frame by connecting assembly, screening mesh is provided in the screening frame, the side of the support is provided with driving structure, the collection frame is power connected with the driving structure and the lower end of the collection frame is provided with roller matched with the support, the screening mesh is connected between the screening frame by mounting assembly;

[0008] The connecting assembly includes a connecting arm fixedly arranged on the collection frame, the connecting arm is rotatably connected with the screening frame, and the connecting assembly further includes an adjusting structure for adjusting the height of one end of the screening frame.

[0009] Further, the adjusting structure includes a first connecting rod rotatably connected with the screening frame, a second connecting rod rotatably arranged on the first connecting rod, and a guide member arranged on one side of the collection frame and matched with the second connecting rod.

[0010] Further, a driving rod is rotatably arranged on the second connecting rod, a nut seat is fixedly arranged on the driving rod, and a lead screw is rotatably arranged on the collection frame and threadedly connected with the nut seat.

[0011] Further, the mounting assembly includes a support frame fixedly arranged on the screening frame, a plurality of mounting grooves are formed in the support frame, and an insertion block matched with the mounting grooves is fixedly arranged on the screening mesh.

[0012] Further, a limiting structure is arranged on the insertion block, and a positioning glass bead matched with the limiting structure is fixedly arranged on the support frame.

[0013] Further, the limiting structure includes two limiting rods rotatably connected with each other, a T-shaped block is rotatably arranged at the other end of each limiting rod, and a sliding groove matched with the T-shaped block is formed in each insertion block.

[0014] The screening structure for ore sand production has the following beneficial effects:

[0015] In the utility model, the height of one end of the screening frame is adjusted by the adjusting structure, so that the screening frame can be adjusted in angle along the connecting arm. When large-particle zircon sand needs to be screened, the angle is adjusted to be small, so as to increase the residence time of zircon sand on the screening mesh, and the zircon sand is fully screened, avoiding the zircon sand from flowing away directly under the action of gravity.

[0016] Secondly, in the utility model, the screening mesh is connected with the screening frame by the mounting assembly, which facilitates the replacement of the screening mesh with a desired mesh size, and facilitates the removal and cleaning of the screening mesh. BRIEF DESCRIPTION OF DRAWINGS
