Description

Technical Field

[0001] This utility model relates to a mineral product screening device, belonging to the field of mineral sample screening technology. Background Technology

[0002] my country has a complex and diverse geological structure, rich in various minerals. "Geological exploration" refers to the investigation and research activities conducted through various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. It involves investigating and researching the geological conditions of a specific area, including rocks, strata, structures, minerals, hydrology, and geomorphology, to ascertain the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and to provide the necessary mineral reserves and geological data for mine construction design.

[0003] When conducting mineral exploration, in order to facilitate the testing of ore composition, it is necessary to crush the ore and take samples. When crushing the ore, it is generally crushed into particles of different sizes, and then a screening device is used to classify it. Through classification, it is screened into various samples of different sizes for subsequent use.

[0004] Existing screening devices typically consist of multiple layers of screens inside a screening box. Mineral products are poured onto the screens, and the screens are shaken to select mineral products of suitable size. These screening devices are generally relatively large, and due to the limited length of the screens, the screening effect is not ideal. Therefore, some screening devices also require the installation of vibrating motors to improve the screening effect, which complicates the structure of the screening device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a mineral product screening device.

[0006] The technical solution adopted by this utility model is as follows: a mineral product screening device is designed, which includes a cylinder, a column, spiral screening blades and spiral guide blades. The column is arranged inside the cylinder, and multiple spiral screening blades are arranged on the column. All the spiral screening blades and the spiral guide blades are arranged in an array from top to bottom along the axial direction of the column. The spiral screening blades are provided with dense screen holes, and the screen hole diameter on the spiral screening blades on the column decreases step by step from top to bottom. A cylinder cover is provided at the upper end of the cylinder, and a feed hopper is provided on the cylinder cover. The discharge port of the feed hopper is directly opposite the upper end of the spiral screening blade located on the uppermost side of the column.

[0007] The upper ends of all the spiral screening blades and the spiral guiding blades are located on the same side of the column, and the lower ends of all the spiral screening blades and the spiral guiding blades are arranged in a circumferential array along the column.

[0008] Furthermore, this design also includes a sealing plate, the upper ends of all the spiral screening blades and the spiral guide blades are welded and fixed to the sealing plate, the upper end of the sealing plate is higher than the upper end of the spiral screening blades located on the uppermost side of the column, and the lower end of the sealing plate is welded and fixed to the upper end of the spiral guide blades.

[0009] Furthermore, this design also includes guide plates, with guide plates of different heights set at the lower ends of all spiral screening blades and spiral guide blades, and the lower ends of all guide plates are flush.

[0010] Furthermore, this design also includes a base. The base is provided at the lower end of the cylinder. The base includes a bottom plate, a support shaft, and a partition. The support shaft is provided in the middle of the bottom plate and is directly opposite the column. The partition is provided on the base at the position corresponding to the guide plate.

[0011] Furthermore, the inner side of the partition plate is welded and fixed to the support shaft, and the outer side extends beyond the guide plate and into the lower end of the cylinder to support it.

[0012] Furthermore, the lower end of the cylinder is provided with connecting ear plates that correspond one-to-one with the guide plates. The guide plates and partitions are respectively provided with connecting holes, and the connecting ear plates are also provided with corresponding connecting holes. The ear plates are respectively connected and fixed to the guide plates and partitions by bolt assemblies.

[0013] Furthermore, a flange is provided at the upper end of the cylinder, and the cylinder cover is locked to the flange by bolts.

[0015] Furthermore, a handle buckle is provided on each of the opposite sides of the cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses a spiral sieve plate structure for screening, which can greatly reduce the volume (especially the lateral volume) of traditional mineral sample screening devices. It also adopts a multi-layer design, which can perform multi-stage screening at one time, making it convenient to use. The spiral sieve plate can automatically and quickly screen mineral samples without the need for a vibration structure, and the screening effect is better. The overall structure is also simpler.

[0018] This invention utilizes a spiral screen for ore screening. When ore is placed on the screen, the screened ore is quickly conveyed to the outlet, significantly improving screening efficiency. It allows for simultaneous ore screening and conveying, thereby enhancing screening efficiency. Furthermore, the overall structure employs a detachable connection and assembly, making replacement and maintenance more convenient. Attached Figure Description

[0027] Example 1

[0028] like Figure 1-2As shown, a mineral product screening device includes a cylinder 1, a column 2, spiral screening blades 3, and spiral guide blades 4. The column 2 is located in the middle of the cylinder 1. Multiple spiral screening blades 3 are mounted on the column 2. All spiral screening blades 3 and spiral guide blades 4 are arranged in an array from top to bottom along the axial direction of the column 2 and are welded and fixed to the column 2. The spiral screening blades 3 have densely packed screen holes, and the screen hole diameter on the spiral screening blades 3 on the column 2 decreases progressively from top to bottom, meaning that the screen hole size is different on different spiral screening blades 3, thereby achieving mineral sample grading. In addition, the spiral screening blades 3 also serve to transport the screened mineral sample, and the spiral guide blades 4 similarly serve to transport the bottom layer of screened mineral sample. A cylinder cover 5 is provided at the upper end of the cylinder 1, and a feed hopper 6 is provided on the cylinder cover 5 for easy loading. The discharge port of the feed hopper 6 is directly opposite the upper end of the spiral screening blades 3 located on the uppermost side of the column 2.

[0029] The upper ends of all the spiral screening blades 3 and the spiral guiding blades 4 are located on the same side of the column 2, so that each spiral screening blade 3 is utilized to the maximum extent. The lower ends of all the spiral screening blades 3 and the spiral guiding blades 4 are arranged in a circumferential array along the column 2. With this arrangement, outlets for different levels of mineral samples can be formed at the lower end of the cylinder 1, which is convenient for collection.

[0030] Example 2

[0031] This embodiment is a further optimization and refinement of the screening device structure based on implementation 1, specifically as follows:

[0032] The mineral screening device described in this embodiment also includes a sealing plate 7. The upper ends of all the spiral screening blades 3 and the spiral guide blades 4 are welded and fixed to the sealing plate 7. The upper end of the sealing plate 7 is higher than the upper end of the spiral screening blades 3 located on the uppermost side of the column 2 (similarly, the end cap is set higher than the upper end of the spiral screening blades 3 located on the uppermost side of the column 2 to facilitate material discharge and prevent blockage). This prevents material from splashing to other areas before falling onto the spiral screening blades 3 and when falling onto the spiral screening blades 3. The lower end of the sealing plate 7 is welded and fixed to the upper end of the spiral guide blades 4.

[0033] In this embodiment, the mineral product screening device also includes a guide plate 8. The lower ends of all the spiral screening blades 3 and the spiral guide blades 4 are respectively welded and fixed with guide plates 8 of different heights. The lower ends of all the guide plates 8 are flush, forming different discharge ports.

[0034] Example 3

[0035] This embodiment is a further optimization and refinement of the screening device structure based on implementation 2, specifically as follows:

[0036] The mineral screening device described in this embodiment also includes a base 9, such as... Figure 4 As shown, a base 9 is provided at the lower end of the cylinder 1. The base 9 includes a bottom plate 10, a support shaft 11 and a partition plate 12. The support shaft 11 is provided in the middle of the bottom plate 10. The support shaft 11 is directly opposite the column 2. The partition plate 12 is provided on the base 9 at the position corresponding to the guide plate 8.

[0037] In this embodiment, the inner side of the partition plate 12 is welded and fixed to the support shaft 11, and the outer side extends beyond the guide plate 8 and into the lower end of the cylinder 1 to support it.

[0038] The base 9 provides reliable support for the cylinder 1 structure and facilitates the placement of the overall screening device. It also facilitates the collection of the screened mineral samples.

[0039] Example 4

[0040] This embodiment is a further optimization and refinement of the screening device structure based on implementation 3, specifically as follows:

[0041] like Figure 3 As shown, in this embodiment of the mineral product screening device, the lower end of the cylinder 1 is provided with connecting ear plates 13 that correspond one-to-one with the guide plate 8. The guide plate 8 and the partition plate 12 are respectively provided with connecting holes, and the connecting ear plates 13 are also provided with corresponding connecting holes. The ear plates are respectively connected and fixed to the guide plate 8 and the partition plate 12 by bolt assemblies.

[0042] In this embodiment, the upper end of the cylinder 1 of the mineral product screening device is provided with a flange, and the cylinder cover 5 is locked to the flange by bolts.

[0043] The entire screening device has a detachable connection (the cylinder 1 and the end cover are detachable, the cylinder 1 and the spiral blades are detachable, and the cylinder 1 and the base 9 are detachable), which facilitates disassembly, assembly, cleaning, and maintenance.

[0044] Example 5

[0045] This embodiment is a further optimization and refinement of the screening device structure based on implementation 4, specifically as follows:

[0046] The mineral screening device described in this embodiment also includes a collection hopper 14. A collection hopper 14 is provided between each pair of partitions 12 to facilitate the collection of the screened mineral sample. The height of the collection hopper 14 is lower than the height of the partitions 12, so that the operator can easily observe the screening situation at the collection end.

[0047] The mineral screening device described in this embodiment is further provided with handles 15 on opposite sides of its cylinder 1 to facilitate moving the entire device.

[0048] Since some mineral sample screening is carried out directly in the field and others in the laboratory, this application can be designed with different sizes of structures according to different usage scenarios. For field use, it is designed to be small and portable, while for laboratory use, it is designed to be large and have stronger screening capabilities.

[0049] When using this application, the ore sample to be screened is poured into the feed hopper 6, and then the screened ore sample can be obtained through the collection hopper 14. The overall structure is simple and easy to operate.

[0050] Furthermore, in the description of this utility model, unless otherwise stated, the terms "multiple," "multiple roots," and "multiple groups" mean two or more, and "several," "several roots," and "several groups" mean one or more. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.
