Description

Technical Field

[0001] This utility model belongs to the field of grinding mill technology, specifically relating to a multi-stage iron removal device for grinding mills. Background Technology

[0002] Grinding mills are widely used in the grinding and processing of mineral materials in metallurgy, building materials, chemical industry, mining and other fields. Nowadays, grinding mills are divided into various types according to the fineness of the final powder. The most commonly used type is the straight-through grinding mill. After the grinding mill produces the final material, in order to remove excess iron filings from the material, the material is put back into a screening and iron removal device. The iron removal device itself is used to collect and remove the iron filings separately.

[0003] The existing iron removal device screens the material processed by the grinding mill separately. However, there are some problems in actual use. Specifically, the existing iron removal device requires separate feeding, which results in a certain amount of working time being spent on material conveying and feeding, thus affecting the overall work efficiency. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0006] A multi-stage iron removal device for a grinding mill includes a processing cylinder and connecting flanges. The processing cylinder is located below the discharge port of the grinding mill and has a hollow tubular structure. Connecting flanges are installed at the top and bottom openings of the processing cylinder. The processing cylinder is connected to the discharge port of the grinding mill through the connecting flanges. The material processed by the grinding mill enters the processing cylinder through the discharge port. A screening component is installed inside the processing cylinder to quickly screen iron filings in the material during the material flow process.

[0007] As a preferred technical solution of this utility model, the screening component includes an adsorption component and a positioning component. Multiple sets of adsorption components are installed at equal intervals inside the processing cylinder, wherein multiple adsorption components form an adsorption layer, and a total of three adsorption layers are provided inside the processing cylinder.

[0008] As a preferred embodiment of this invention, a gap is left between the adsorption layers for material flow, and the adsorption components in the three adsorption layers are staggered.

[0009] As a preferred embodiment of this utility model, the adsorption assembly includes a top shell, a lower shell, and a strong magnetic rod. The top shell is installed inside the processing cylinder, and the lower shell is installed at the bottom of the top shell. The top shell and the lower shell are provided with a common mounting groove. The strong magnetic rod is slidably installed in the mounting groove. When the strong magnetic rod is energized, it processes the material passing through the surface of the top shell and uses magnetism to adsorb iron filings in the material. A guide plate is installed at the bottom of the lower shell to guide the flow direction of the material.

[0010] As a preferred technical solution of this utility model, the positioning component includes a base plate and a limiting member. The base plate is installed at the end of the lower housing and is located directly below the strong magnetic rod. A limiting member is installed on the base plate to limit the position of the strong magnetic rod.

[0011] As a preferred technical solution of this utility model, the limiting component includes a limiting block. The limiting block is installed on the surface of the base plate. The limiting block is mainly composed of a spring sheet and a locking plate. The spring sheet is installed on the surface of the base plate, and the locking plate is installed at the end of the spring sheet.

[0012] As a preferred technical solution of this utility model, the limiting member includes a pressing screw, and a threaded groove is provided on the base plate, with the pressing screw threadedly installed in the threaded groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a screening component and a processing cylinder. The processing cylinder is directly installed at the bottom discharge port of the mill. After the material enters the processing cylinder, the adsorption component collects and absorbs the iron filings. The staggered and multi-layered distribution of the adsorption components in the screening component enables step-by-step screening of the iron filings in the material, achieving efficient iron filings removal without the need for subsequent conveying of the material output from the mill. This ensures the iron removal effect of the material. The limiting component in this invention allows for quick positioning and disassembly of the strong magnetic rod, facilitating subsequent maintenance of the strong magnetic rod.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0025] Example 1 like Figure 1 and Figure 2 As shown, this is a schematic diagram of the multi-stage iron removal device for the grinding mill in this embodiment. The iron removal device in this embodiment is directly installed at the discharge port of the grinding mill. After the grinding mill finishes processing, the material is directly discharged from the discharge port of the grinding mill. During the discharge process, the iron removal device removes iron filings from the material between the discharge port and when the material falls into the collection bin, thus accelerating the overall working efficiency. The iron removal device includes a processing cylinder 1, a screening component 2, and a connecting flange 3. The processing cylinder 1 is a hollow tubular structure, and connecting flanges 3 are installed at the top and bottom openings of the processing cylinder 1. The processing cylinder 1 is installed at the discharge port of the grinding mill through the use of one set of connecting flanges 3. The material in the grinding mill enters the processing cylinder 1 through the discharge port. The screening component 2, which removes and screens iron filings from the material, is installed inside the processing cylinder 1.

[0026] As attached Figure 3 , Figure 4 and Figure 5 As shown, this is a schematic diagram of the structure of the screening component 2 in this embodiment. The screening component 2 includes a top shell 21, a lower shell 22, and a strong magnetic rod 23. The top shell 21 is installed inside the processing cylinder 1, and the lower shell 22 is installed at the bottom of the top shell 21. The top shell 21 and the lower shell 22 share an installation groove, in which the strong magnetic rod 23 for collecting iron filings in the material is installed. In this embodiment, the top shell 21, the lower shell 22, and the strong magnetic rod 23 form a single adsorption component, and multiple adsorption components form a single-layer adsorption layer. The processing cylinder 1 has three adsorption layers, with gaps between the adsorption components for material flow. The three adsorption layers are staggered, with the adsorption components in the second layer installed in the gaps between the adsorption components in the previous layer, distributed step by step to screen the material entering the processing cylinder 1. The bottom of the lower shell 22 is symmetrically equipped with guide plates 24, and the guide plates 24 form conical filter holes to guide the material passing through, allowing the material screened in the previous adsorption layer to fall onto the surface of the adsorption components in the next layer.

[0027] As attached Figure 5 As shown, this is a schematic diagram of the structure of the screening component 2 in this embodiment. The screening component 2 includes a base plate 25 and a limiting member 26. The base plate 25 is installed on one side of the lower housing 22. The limiting member 26 is installed on the base plate 25 to lock the position of the strong magnetic rod 23. The base plate 25 and the limiting member 26 form the locking component in this embodiment. By using the locking component, the strong magnetic rod 23 inserted into the mounting slot can be quickly positioned and pulled out, which facilitates subsequent maintenance of the strong magnetic rod 23.

[0028] As attached Figure 6 As shown, this is a schematic diagram of the structure of the limiting member 26 in this embodiment. The limiting member 26 includes a limiting block 261. The limiting block 261 is installed on the upper surface of the base plate 25. The limiting block 261 is mainly composed of a spring sheet and a locking plate. The spring sheet is installed on the surface of the base plate 25, and the locking plate is installed at the end of the spring sheet. When the strong magnetic rod 23 is inserted into the mounting groove, the spring sheet and the locking plate are squeezed by the strong magnetic rod 23 and tilted towards the side closer to the surface of the base plate 25. After the strong magnetic rod 23 enters the target position, the locking plate bounces up under the elastic force of the spring sheet. The locking plate squeezes and locks the end position of the strong magnetic rod 23 to prevent the strong magnetic rod 23 from falling out of the mounting groove.

[0029] Example 2 As attached Figure 7As shown, it is a structural schematic diagram of the limiting member 26 in this embodiment. The difference between this embodiment and embodiment 1 is that the limiting member 26 in this embodiment includes a pressing screw 262. A threaded groove is provided on the base plate 25. The pressing screw 262 is threadedly installed in the threaded groove. The end of the pressing screw 262 is in pressing contact with the strong magnetic rod 23. The pressing screw 262 presses and limits the position of the end of the strong magnetic rod 23.

[0030] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
