Description

Technical Field

[0001] This utility model relates to the field of magnetic separator unloading technology, specifically a CTB permanent magnet unloading water nozzle arrangement structure. Background Technology

[0002] Magnetic separators are commonly used in iron ore beneficiation. Currently, the beneficiation department has 101 permanent magnet separators, of which 52 are in regular operation. Their operational status directly affects the final iron concentrate quality. "Uniform feeding and clean unloading" are the most basic requirements for magnetic separation operations.

[0003] Currently, magnetic separators on-site exhibit varying degrees of ore-carrying issues in their drums. Analysis of the causes reveals that the unreasonable arrangement of the discharge nozzles is a significant problem. This is mainly manifested in the pressure of the spray fan-shaped surfaces of adjacent nozzles canceling each other out, resulting in a weakened impact force on the drum. Consequently, ore is carried onto the roller at the intersection of the spray fan-shaped surfaces of adjacent nozzles. Furthermore, a single discharge nozzle is prone to clogging and is difficult to disassemble. Therefore, this invention provides a discharge nozzle arrangement structure for a CTB permanent magnet separator to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a CTB permanent magnet machine unloading water nozzle arrangement structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CTB permanent magnet machine unloading water nozzle arrangement structure, including a drain pipe, a first drain seat, a second drain seat, and a drain head. The first drain seat is installed at the front end of the drain pipe, and a second drain seat is welded to the adjacent position of the first drain seat. Multiple first and second drain seats are provided. The first and second drain seats are arranged in an alternating vertical structure, and a detachable drain head is threadedly connected to both the first and second drain seats.

[0006] Both the first and second drain seats are connected to the drain pipe through drain channels at their inner ends. Gaskets are installed at the inner ends of the first and second drain seats. The drain heads installed on the first and second drain seats form a compression structure with the gaskets. A detachable filter screen is installed inside the drain head. A drain outlet is opened at the right end inside the drain head.

[0007] As a preferred embodiment of this utility model, the drain pipe is a stainless steel pipe with a diameter of 80mm.

[0008] In a preferred embodiment of this invention, the length of the second drainage seat is four times that of the first drainage seat.

[0009] In a preferred embodiment of this invention, the drainage channel and the drainage outlet are connected and have the same diameter, with the diameter of the drainage channel being 5mm.

[0010] As a preferred embodiment of this invention, the gasket is a soft rubber with a circular structure.

[0011] As a preferred embodiment of this utility model, grooves are provided on both the upper and lower sides of the left end face of the filter screen.

[0012] In a preferred embodiment of this invention, the drain pipe is located more than 200 mm from the edge of the magnetic pole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by providing drainage seats with an alternating upper and lower structure at the front end of the drainage pipe, and the adjacent drainage seats having different lengths, the pressure of the fan-shaped surfaces of the water spray from two adjacent drainage heads can be offset, thereby reducing the impact force on the cylinder and carrying away ore. This achieves clean ore unloading from the permanent magnet cylinder, improves the yield of permanent magnet operations, and reduces metal loss.

[0015] 2. In this utility model, a detachable filter screen is provided inside the drain head, which can filter impurities in the liquid. In addition, grooves are provided on the upper and lower sides of the left end face of the filter screen to facilitate the removal of the filter screen. Attached Figure Description

[0025] Example: Figure 1-5 The present invention provides a technical solution including a drain pipe 1, a first drain seat 2, a second drain seat 3 and a drain head 4. The first drain seat 2 is installed at the front end of the drain pipe 1, and the second drain seat 3 is welded to the adjacent position of the first drain seat 2. There are multiple first drain seats 2 and second drain seats 3. The first drain seats 2 and second drain seats 3 are arranged in an alternating structure. The first drain seat 2 and the second drain seat 3 are all connected to a detachable drain head 4 by threads 9.

[0026] Both the first drain seat 2 and the second drain seat 3 are connected to the drain pipe 1 through the drain channel 7. Gaskets 5 are installed at the inner ends of the first drain seat 2 and the second drain seat 3. The drain head 4 installed on the first drain seat 2 and the second drain seat 3 forms a compression structure with the gasket 5. A detachable filter screen 6 is installed inside the drain head 4. A drain outlet 8 is opened at the right end inside the drain head 4.

[0027] Drain pipe 1 is a stainless steel pipe with a diameter of 80mm, which makes drainage smoother.

[0028] The length of the second drainage seat 3 is 4 times that of the first drainage seat 2. The pressure of the fan-shaped surfaces of the water spray from the two adjacent drainage heads cancels each other out, resulting in a reduction of the impact force on the cylinder and thus carrying away the ore.

[0029] The drainage channel 7 and the drainage outlet 8 are connected and have the same diameter. The diameter of the drainage channel 7 is 5mm, which makes the drainage smooth and avoids blockage.

[0030] Gasket 5 is made of soft rubber with a circular structure, which increases the sealing between the drain head and the drain seat and prevents water leakage.

[0031] The filter screen 6 has grooves 10 on both the top and bottom sides of its left end face to facilitate the removal of the filter screen for cleaning impurities.

[0032] The drain pipe 1 is more than 200mm away from the edge of the magnetic pole.

[0033] Working principle:

[0034] In use, when water is transmitted through the drain pipe 1, it is transmitted through the drain channel 7 in the first drain seat 2 and the second drain seat 3 to the drain outlet 8 in the drain head 4 and discharged through the drain outlet 8. When water is discharged through the drain head 4, the filter screen 6 inside the drain head 4 can filter impurities. The pressure of the fan-shaped spray surface of the two adjacent drain heads cancels each other out, which weakens the impact force on the cylinder and carries away the ore, thereby achieving clean ore unloading of the permanent magnet cylinder, improving the yield of permanent magnet operation, and reducing metal loss. The drain head 4 is threadedly connected to the drain seat through the thread 9 and can be disassembled. After disassembly, the filter screen 6 is removed by inserting a tool into the groove 10 opened on the filter screen 6, the impurities are removed, and then it is installed in the drain head 4 and then installed on the drain seat.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
