Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, in particular to a device for adjusting a flow gap of a magnetic separator. Background Art

[0002] A magnetic separator is a device that uses the response of a substance to a magnetic field to separate a mixture. The basic principle is that when one or more substances in a mixture have a certain magnetic property, they will be deflected or moved by the magnetic force when placed in a magnetic field, thereby achieving separation of the mixture.

[0003] At present, there are some problems in the actual operation of the common magnetic separators in my country. For example, since the size of the magnetic powder adsorption chamber cannot be adjusted, the flow gap for the sludge with magnetic powder to enter the magnetic powder adsorption chamber cannot be adjusted, resulting in unsatisfactory magnetic separation effect when the water flow decreases. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a device for adjusting the flow gap of a magnetic separator, which overcomes the deficiencies of the prior art and effectively solves the problem of poor magnetic separation effect due to reduced flow.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for adjusting the flow gap of a magnetic separator comprises a casing, a dispersion channel is welded on one side of the outer wall of the casing, a mud inlet pipe is welded on one side of the outer wall of the dispersion channel, and a separator strip distributed at equal distances is welded on the inner wall of the dispersion channel;

[0007] A magnetic powder adsorption chamber is arranged inside the casing, and a water inlet plate is rotatably connected to an inner wall of one side of the magnetic powder adsorption chamber, symmetrically distributed springs are connected between the water inlet plate and the casing, and a screw is screwed to an inner wall of one side of the casing.

[0008] Preferably, the outer wall of one end of the screw rod is tightly attached to the outer wall of the water inlet plate.

[0009] Preferably, a servo motor is fixedly connected to an outer wall of one side of the casing by bolts, and an output shaft of the servo motor is connected to a magnetic roller by a coupling.

[0010] Preferably, a flushing pipe is installed on the top of the inner wall of the casing, and nozzles distributed at equal distances are installed on the outer wall of the flushing pipe.

[0011] Preferably, a discharge port is provided on the outer wall of the other side of the housing, and a scraper is welded on the inner wall of the discharge port, and the outer wall of one end of the scraper is tightly attached to the inner wall of the magnetic powder adsorption chamber.

[0012] Preferably, a mud outlet pipe is welded to the inner wall of the bottom of the casing.

[0013] Preferably, symmetrically distributed support frames are welded to the outer wall of the bottom of the casing.

[0014] The beneficial effects of the utility model are:

[0015] 1. The magnetic separator of this design has a device for adjusting the flow gap. A mud inlet pipe and a dispersion channel are added in the feeding direction of the casing. Since equidistantly distributed separators are installed in the dispersion channel, many sub-chambers are formed. The sludge entering from the mud inlet pipe will be dispersed when passing through the dispersion channel, which reduces the stacking thickness of the sludge, increases the feeding area, and improves the adsorption effect.

[0016] 2. The magnetic separator designed in this invention has a device for adjusting the flow gap, and adds a water inlet plate with an adjustable gap. The water inlet plate is connected to the water inlet plate through a spring to provide a buffer. When the screw rod is rotated, the length of the screw rod in the magnetic powder adsorption chamber can be adjusted, thereby controlling the inclination angle of the water inlet plate.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Embodiment 1, refer to Figure 1-3 A device for adjusting the flow gap of a magnetic separator comprises a casing 1, a dispersion channel 2 is welded on one side of the outer wall of the casing 1, a mud inlet pipe 3 is welded on one side of the outer wall of the dispersion channel 2, and a dividing strip 4 equidistantly distributed is welded on the inner wall of the dispersion channel 2.

[0023] In this embodiment, a mud inlet pipe 3 and a dispersion channel 2 are added in the feeding direction of the casing 1. Since equidistantly distributed dividing strips 4 are installed in the dispersion channel 2, a large number of sub-chambers are formed. The sludge entering from the mud inlet pipe 3 will be dispersed when passing through the dispersion channel 2, thereby reducing the stacking thickness of the sludge, increasing the feeding area, and improving the adsorption effect.

[0024] Example 2, refer to Figure 1-3 A device for adjusting the flow gap of a magnetic separator, a magnetic powder adsorption chamber 5 is arranged inside a casing 1, and a water inlet plate 6 is rotatably connected to the inner wall of one side of the magnetic powder adsorption chamber 5, symmetrically distributed springs 7 are connected between the water inlet plate 6 and the casing 1, and a screw rod 8 is screwed to the inner wall of one side of the casing 1.

[0025] In this embodiment, a water inlet plate 6 with an adjustable gap is added, and the water inlet plate 6 is connected by a spring 7 to provide a buffer. When the screw rod 8 is rotated, the length of the screw rod 8 in the magnetic powder adsorption chamber 5 can be adjusted, thereby controlling the inclination angle of the water inlet plate 6. The flow gap is increased or decreased according to the situation, and the adsorption effect is further increased.

[0026] Reference Figure 1-3 The outer wall of one end of the screw rod 8 is closely attached to the outer wall of the water inlet plate 6.

[0027] Reference Figure 2-3 A servo motor 9 is fixedly connected to the outer wall of one side of the casing 1 by bolts, and the output shaft of the servo motor 9 is connected to a magnetic roller 10 by a coupling.

[0028] Reference Figure 3 A flushing pipe 11 is installed on the top of the inner wall of the casing 1, and nozzles 12 distributed at equal distances are installed on the outer wall of the flushing pipe 11.

[0029] Reference Figure 2 A discharge port is provided on the outer wall of the other side of the housing 1 , and a scraper 13 is welded on the inner wall of the discharge port. The outer wall of one end of the scraper 13 is closely attached to the inner wall of the magnetic powder adsorption chamber 5 .

[0030] Reference Figure 3 A mud outlet pipe 14 is welded to the inner wall of the bottom of the casing 1.

[0031] Reference Figure 1 The outer wall of the bottom of the casing 1 is welded with symmetrically distributed support frames 15.

[0032] Working principle: The magnetic powder will be mixed with the sludge and enter the casing 1 through the mud inlet pipe 3 and the dispersion channel 2. Since the equidistantly distributed dividing strips 4 are installed in the dispersion channel 2, many sub-chambers are formed, which reduces the stacking thickness of the sludge and allows the sludge to be thrown into the magnetic powder adsorption chamber 5 to the greatest extent. At this time, according to the flow rate, the inclination angle of the water inlet plate 6 is controlled by rotating the screw 8, and the flow gap is increased or decreased according to the situation, so that the mixture can fall close to the magnetic roller 10. The magnetic powder adsorbed on the magnetic roller 10 reaches the scraper 13 as the roller rotates, and the scraper 13 scrapes the magnetic powder off to complete the separation of the magnetic powder. The remaining sludge will fall off the magnetic powder and be discharged from the mud outlet pipe 14 at the bottom of the casing 1.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
