[0019] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Example:

[0021] The accompanying drawings illustrate a specific embodiment of a small magnetic separator according to this utility model. Figure 1 It mainly includes a lower bucket body 1, with a connecting flange 2 at the top of the lower bucket body 1, and an upper bucket body 3 connected to the upper part of the connecting flange 2.

[0022] The lower barrel 1 has a cylinder sleeve 4 inside, which is sealed to the connecting flange 2. A lifting cylinder 5 is installed inside the cylinder sleeve 4. The top of the lifting cylinder 5 is located inside the upper barrel 3 and is connected to a cylinder fixing plate 14. The cylinder fixing plate 14 is fixedly connected to the connecting flange 2 by cylinder tie rod bolts 15. The output shaft of the lifting cylinder 5 is connected to a top plate 16, and a magnetic rod 6 is connected to the top plate 16.

[0023] The magnetic rod 6 can be lifted and inserted into the magnetic rod sleeve 7. The magnetic rod sleeve 7 passes through the connecting flange 2 and is inserted into the lower barrel 1, and the magnetic rod sleeve 7 and the connecting flange 2 are sealed together. The bottom end of the magnetic rod sleeve 7 is set close to the bottom wall of the lower barrel 1.

[0024] The lower barrel 1 has an inlet 8 on the upper part of one side and an outlet 9 on the lower part of the other side. The rear end of the inlet 8 is connected in sequence to a perforated plate 10, a diffuser 11, and a honeycomb guide 12. The honeycomb guide 12 is connected to the lower barrel 1 and communicates with the interior of the lower barrel 1.

[0025] The perforated plate 10 is used to disperse the liquid flow into multiple fine streams. The perforated plate 10 is made of stainless steel or PTFE to avoid magnetic interference. The diffuser 11 is used to reduce the inlet flow velocity and evenly distribute the flow rate. The honeycomb guide 12 has a plate-like structure, combined with... Figure 2 The honeycomb flow guide 12 has several honeycomb holes 12a, and the side length of each honeycomb hole 12a is 2 to 5 mm. The honeycomb flow guide 12 is used to eliminate turbulent vortices. The honeycomb flow guide 12 is made of resin to avoid magnetic interference.

[0026] Inside the lower barrel 1, there are two inclined guide plates 13 arranged vertically. The two inclined guide plates 13 are used to guide the water flow introduced by the honeycomb guide 12 to the magnetic rod sleeve 7 in layers.

[0027] Specifically, both inclined guide plates 13 are inclined downwards at an angle of 5° to 15°. The inclined guide plates 13 are fixedly connected to the inner wall of the lower tank 1, dividing the internal space of the lower tank 1 into multiple layers, and there is a gap between the inclined guide plates 13 and the magnetic rod sleeve 7. Each of the two inclined guide plates 13 has an opening in the middle, and the outer wall of the cylinder sleeve 4 fits against the inner wall of the opening of the two inclined guide plates 13 to prevent water from flowing through.

[0028] An upper inclined guide plate 13 is positioned between the honeycomb guide 12 and the magnetic rod sleeve 7. This inclined guide plate 13 has a closed plate structure and is used to divide the water flow introduced by the honeycomb guide 12 into upper and lower layers. A lower inclined guide plate 13 is located below the honeycomb guide 12. This inclined guide plate 13 has a diversion hole 13a, which, combined with... Figure 3 The diversion hole 13a is an inclined hole, and its inclination direction is opposite to that of the inclined guide plate 13. The lower layer of water flow, which is diverted by the upper inclined guide plate 13, is then divided into two layers by the lower inclined guide plate 13. The liquid flow can enter the bottom of the lower tank 1 through the diversion hole 13a, thereby dividing the incoming water into three layers and guiding it to the magnetic rod sleeve 7. The diversion hole 13a and the inclined guide plate 13 are set in opposite inclination directions to prevent the water flow from falling directly to the bottom of the lower tank 1 along the diversion hole 13a, thus ensuring the stratification effect.

[0029] The two inclined guide plates 13 are also fixedly connected to the bottom wall of the lower barrel 1 by a support rod 17 at one end near the magnetic rod sleeve 7, which serves to strengthen the structure.

[0030] Furthermore, the outlet 9 is connected to the outlet pipe 18 and the drain pipe 19 respectively, and the outlet pipe 18 and the drain pipe 19 are respectively equipped with a first valve 20 and a second valve 21.

[0031] In the specific operation of this embodiment, in combination with Figure 4 During the magnetic separator filtration process, liquid containing iron filings and impurities flows in through inlet 8, passes through perforated plate 10, diffuser 11, and honeycomb guide 12, and enters the lower tank 1. The incoming water is first divided into upper and lower layers by an upper inclined guide plate 13, and then further divided by a lower inclined guide plate 13 through the diversion hole 13a, ultimately dividing the incoming water into three layers and guiding it to the magnetic rod sleeve 7, thereby improving the separation efficiency. At this time, the magnetic rod 6 is located inside the magnetic rod sleeve 7, and the iron filings in the liquid are attracted by the strong magnetic force and adhere to the magnetic rod sleeve 7. The clean liquid flows out from the outlet pipe 18 (at this time, the first valve 20 is open and the second valve 21 is closed).

[0032] Combination Figure 5When the magnetic separator is being cleaned and slag is being discharged, the cleaning cycle can be set. During cleaning, the lifting cylinder 5 drives the top plate 16 to lift the magnetic rod 6 to the upper part of the upper barrel 3, and the lower part is demagnetized. The iron filings outside the magnetic rod sleeve 7 are discharged from the magnetic separator with the liquid through the drain pipe 19 under the action of gravity and the flushing action of the flowing liquid (at this time, the second valve 21 is open and the first valve 20 is closed).

[0033] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
