Description

Technical Field

[0001] The invention relates to solid particle iron removal equipment, which is used for removing iron powder in the production process of solid particles such as carbon black. Background Art

[0002] In the production and transportation of carbon black and other particulate matter, the iron remover is a device that uses a strong magnetic field to screen out unexpected iron impurities in the product, with the main function of reducing product impurities and improving product quality. Iron removers are widely used in metallurgy, mining, coal preparation plants, power plants, ceramics, glass, cement, building materials, chemicals, food and feed processing industries.

[0003] The most commonly used method of using a drum-type iron remover is that particles enter from one end of the drum, and the drum and the machine body are connected through the drum shaft and bearings. There is a gap between the feed end of the drum and the machine body. When the amount of particles entering is greater than the conveying amount of the drum, the excess particles will enter the gap and hinder the rotation of the drum, increase the rotation resistance of the drum, and easily damage the key connecting the motor and the reducer, causing the motor shaft keyway to wear and require the replacement of the motor rotor. At the same time, the excess particles enter the gap directly without being ironed, resulting in an increase in the iron content of the product. The particles entering the gap are ground by the rotating drum and the stationary machine body, resulting in an increase in fine powder in the particles, which reduces the quality of the product.

[0004] In addition, since the magnetic bar is fixed on the inner circumference of the drum, the magnetic bar must be removed to clean the iron pins on the magnetic bar. Stopping the machine for cleaning leads to low production efficiency, and improper installation during repeated disassembly can easily cause damage to the equipment. Summary of the invention

[0005] Therefore, the object of the present invention is to provide a rotary iron remover capable of synchronous and automatic iron removal.

[0006] The invention comprises a machine body, a rotating shaft, a magnetic rod, an iron cleaning belt and a shifting block.

[0007] The body is a cylindrical structure, including a magnetic plate, an O-ring, front and rear cover plates, a spacer, a sealing filler, a sealing cover, a seat, front and rear shaft bearings, front and rear rear cover plates, a partition plate, etc. The upper part of the body is connected with a feed inlet, and the lower part is connected with a discharge port and an outlet for ferrous materials, and a hole is opened on the wall of the discharge port as a dust suction port.

[0008] The rotating shaft is installed axially through the axis of the machine body, and the front end is connected to the driving mechanism for transmission. The rotating shaft is arranged in sequence from the front end to the rear with a front cover, a front rotating shaft bearing, a front cover plate, a solid magnetic plate, a rear cover plate, a sealing filler, a sealing cover, a seat body, a rear rotating shaft bearing, and a rear end cover. The rotating shaft is fixedly connected to the solid magnetic plate by a key, and is respectively connected to the front cover plate and the rear cover plate of the machine body through the front rotating shaft bearing and the rear rotating shaft bearing. The front rotating shaft bearing is installed in the front cover plate, and the rear rotating shaft bearing is installed in the seat body. The front cover and the rear end cover are respectively fixed to the front cover plate and the seat body, thereby axially fixing the front rotating shaft bearing and the rear rotating shaft bearing. The sealing cover fixes the sealing filler to fill the gap between the rotating shaft and the rear cover plate. The solid magnetic plate is radially fixedly installed with a partition, a partition plate and a magnetic rod. The solid magnetic plate is fixedly connected to the outer wall of the machine body and an O-ring is installed between the two.

[0009] The magnetic bar is a columnar body, including a magnetic bar front end cover, a magnetic bar rotating wheel, a magnetic bar bearing, a permanent magnet, a soft magnet, a cast iron part, a sheath, a magnetic bar rear end cover and a magnetic isolation body. The magnetic bar is circumferentially arranged in the area outside the isolation tube on the solid magnetic plate, and is fixedly connected to the solid magnetic plate through the sheath. The front end of the core shaft of the permanent magnet is fixedly connected to the magnetic bar rotating wheel, and the core shaft of the permanent magnet is axially connected to the magnetic bar bearing through the front end cover and the rear end cover of the magnetic bar, so that the permanent magnet can rotate around the center in the magnetic bar. In the soft magnetic body, the rotation of the permanent magnet around the center of the magnetic bar can change the magnetism of the magnetic bar. The soft magnet and the cast iron part are both composed of two semicircular ring bodies that clamp and fix the magnetic isolation body, and the three are tightly fitted and installed in the sheath body.

[0010] The iron cleaning belt is made of soft elastic material and is fixed on the partition on the machine body by a belt fixing plate. The radially arranged multiple groups of partitions, iron cleaning belts and belt fixing plates form two left and right chambers in the machine body.

[0011] The shifting block is fixedly connected to the front cover plate, and is arranged radially and linearly on the boundary line between the two chambers of the machine body. When the rotating shaft rotates, it acts alternately with the magnetic rod rotating wheel on the magnetic rod. When the magnetic rod rotates to the boundary line between the two chambers with the rotation of the rotating shaft, the shifting block collides with the magnetic rod rotating wheel, and the magnetic rod rotating wheel is shifted to drive the permanent magnet to rotate 90 degrees around the core shaft, so that the magnetic rod changes its magnetic properties.

[0012] The advance angle and lag angle can be set when arranging the shift blocks.

[0013] The particulate matter remover can match the rotation direction of the shaft with the position of the permanent magnets in the left and right cavities of the machine body as needed.

[0014] The particulate matter remover can increase or decrease the number of magnetic bars or change the arrangement of the magnetic bars as needed.

[0015] Beneficial effects of the present invention: A particulate matter remover can automatically and synchronously remove ferrous substances in the particulate matter production process, convert the magnetism through the periodic contact between the magnetic rod and the shift block, and realize the adsorption and release of ferrous substances. The present invention has a simple structure and reliable sealing, and is particularly suitable for the production and transportation of particulate matter, and is mainly used for the sorting and purification of particulate matter. 1) The principle is simple and the structure is reliable. 2) No need to stop the machine for iron removal. 3) Simple operation and easy maintenance.

DETAILED DESCRIPTION

[0028] The invention will be further described below with reference to the embodiments in the accompanying drawings.

[0029] The structure of the particulate matter remover of the present invention is as follows Figures 1 to 4 As shown, it is composed of a body 5, a rotating shaft 23, a magnetic bar 14, an iron cleaning belt 13 and a shifting block 19.

[0030] The body 5 is a cylindrical structure, including a magnetic plate 1, an O-ring 3, a front cover plate 20, a rear cover plate 6, a spacer 7, a sealing filler 8, a sealing cover 9, a seat 10, a front shaft bearing 21, a rear shaft bearing 11, a front cover 22, a rear cover 12, a partition 15, etc. The upper part of the body 5 is connected with an inlet 4, and the lower part is connected with an outlet 17 and an iron material outlet 25. The wall of the outlet 17 is opened as a dust suction port 16.

[0031] The rotating shaft 23 is installed axially through the axis of the machine body 5, and the front end is connected to the driving mechanism for transmission. The rotating shaft 23 is sequentially arranged with a front cover 22, a front rotating shaft bearing 21, a front cover plate 20, a solid magnetic plate 1, a rear cover plate 6, a sealing filler 8, a sealing cover 9, a seat body 10, a rear rotating shaft bearing 11, and a rear end cover 12 from the front end to the rear. The rotating shaft 23 is fixedly connected to the solid magnetic plate 1 through a key 2, and is respectively connected to the front cover plate 20 and the rear cover plate 6 of the machine body 5 through the front rotating shaft bearing 21 and the rear rotating shaft bearing 11. The front rotating shaft bearing 21 is installed in the front cover plate 20, and the rear rotating shaft bearing 11 is installed in the seat body 10. The front cover 22 and the rear end cover 12 are respectively fixed to the front cover plate 20 and the seat body 10, thereby axially fixing the front rotating shaft bearing 21 and the rear rotating shaft bearing 11. The sealing cover 9 fixes the sealing filler 8 to fill the gap between the rotating shaft 23 and the rear cover plate 6. The magnetic plate 1 is radially fixedly mounted with a partition 7, a partition 15 and a magnetic bar 14. The magnetic plate 1 is fixedly connected to the outer wall of the body 5 and an O-ring 3 is installed therebetween.

[0032] like Figure 5 As shown, the magnetic bar 14 is a columnar body, including a magnetic bar front end cover 26, a magnetic bar rotating wheel 18, a magnetic bar bearing 27, a permanent magnet 28, a soft magnet 29, a cast iron part 30, a sheath 31, a magnetic bar rear end cover 32 and a magnetic separator 33. Figures 1 to 4As shown, the magnetic rod 14 is circumferentially arranged in the area outside the partition tube 7 on the solid magnetic plate 1, and is fixedly connected to the solid magnetic plate 1 through the sheath 31. The front end of the core shaft of the permanent magnet 28 is fixedly connected to the magnetic rod rotating wheel 18, and the permanent magnet 28 can rotate around the center in the magnetic rod 14 through the axial connection with the magnetic rod front end cover 26 and the magnetic rod rear end cover 32 and the magnetic rod bearing 27. In the soft magnet 29, the rotation of the permanent magnet 28 around the center of the magnetic rod 14 can change the magnetism of the magnetic rod 14. The soft magnet 29 and the cast iron part 30 are both composed of two semicircular rings that clamp the fixed partition magnet 33, and the three are tightly fitted and installed in the sheath 31.

[0033] like Figure 2 and Figure 7 As shown, the iron cleaning belt 13 is made of soft elastic material and is fixedly mounted on the partition 15 on the machine body 5 by the fixed belt plate 24. The radially arranged multiple groups of partitions 15, iron cleaning belts 13, and fixed belt plates 24 form the machine body 5 into two left and right chambers.

[0034] The shift block 19 is fixedly connected to the front cover plate 20, and is arranged radially and linearly near the boundary line between the two chambers of the body 5. When the rotating shaft 23 rotates, it acts alternately with the magnetic rod rotating wheel 18 on the magnetic rod 14. When the magnetic rod 14 rotates to the boundary line between the two chambers with the rotation of the rotating shaft 23, the shift block 19 collides with the magnetic rod rotating wheel 18, and the magnetic rod rotating wheel 18 is shifted to drive the permanent magnet 28 to rotate 90 degrees around the core axis, so that the magnetic rod 14 changes its magnetic properties.

[0035] Working principle: Figure 2 As shown, if the rotating shaft 23 is driven by the driving mechanism to start to rotate clockwise, the particles with ferrous impurities are put in from the feed port 4. The rotating shaft 23 drives the solid magnetic plate 1 and the magnetic bar 14 installed on the solid magnetic plate 1 to rotate around the rotating shaft, and the front cover plate 20 and the shifting block 19 fixed on the front cover plate 20 remain stationary as the frame. At this time, the relative position of the permanent magnet 28 in the magnetic bar 14 arranged in the right cavity of the body 5 is as shown in FIG. Figure 6 (b) shows that the magnet has magnetism, and the iron substances in the input granular materials are adsorbed on the surface of the magnetic rod 14; as the rotating shaft 23 further rotates, when the magnetic rod 14 arranged in the right cavity reaches the lower dividing line composed of multiple groups of partitions 15, iron cleaning belts 13, and fixed belt plates 24, that is, the left cavity of the machine body 5, the magnetic rod rotating wheel 18 on the magnetic rod 14 is in turn with the magnetic rod rotating wheel 18 on the magnetic rod 14. Figure 4 The block 19 collides with the lower dividing line in the magnet bar 14, causing the permanent magnet 28 in the magnet bar 14 to rotate 90 degrees around the core axis under the drive of the magnet bar rotating wheel 18, resulting in the relative position of the permanent magnet 28 being transformed into Figure 6 As shown in (a), the magnetism disappears, and the ferrous material adsorbed on the magnetic rod 14 is released and discharged through the magnetic material outlet 25 by gravity. Figure 7 In the process from (c) to (b) and then to (a), when the magnetic bar 14 passes the lower dividing line, the process from contact to separation with the iron-cleaning belt 13 completely removes the ferrous substances adsorbed on the surface of the magnetic bar.

[0036] Similarly, the relative position of the permanent magnet 28 in the magnetic bar 14 arranged in the left cavity of the body 5 is as follows: Figure 6 As shown in (a), it is not magnetic until it rotates to the vicinity of the upper dividing line and collides with the shift block 19 near the upper dividing line. The collision process is as follows Figure 8 As shown in (a) to (b), after the collision, the permanent magnet 28 is driven by the magnetic rod rotating wheel 18 to rotate 90 degrees around the core axis of the permanent magnet 28, and the relative position of the permanent magnet 28 is restored to Figure 6 (b) As shown in the figure, the ferrous material is continuously discharged from the ferrous material outlet in such a reciprocating cycle.

[0037] After the iron removal, the particles are discharged through the discharge port 17 and the non-ferrous impurities can be separated and sucked out through the dust suction port 16.

[0038] Preferably, in order to positively cover the iron discharge interval during the rotation cycle, an advance angle and a lag angle can be set when arranging the shift block 19.

[0039] Preferably, the rotation direction of the rotating shaft 23 and the positions of the permanent magnets 28 in the left and right cavities of the body 5 can be matched accordingly as needed.

[0040] Preferably, the number of magnetic bars can be increased or decreased or the arrangement of the magnetic bars can be changed as needed.
