[0026] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the present disclosure and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, one of ordinary skill in the art will understand other possible embodiments and the advantages of the present invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0027] In the description of the present invention, terms such as "up", "down", "left", "right", "front", and "back" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0028] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] Reference Figure 1 、 Figure 2As shown, a slurry iron remover provided in this embodiment includes an iron remover tank body 10, wherein the iron remover tank body 10 is divided into two independent iron removal chambers 101, each iron removal chamber 101 is equipped with a magnetic rod 14 and a group of pipe groups; specifically, in this embodiment, the iron remover tank body 10 includes a tank body 11 having a receiving cavity and a cover plate 12 covering the upper opening of the tank body 11, and the receiving cavity of the tank body 11 is divided into two said iron removal chambers 101 by a vertically arranged partition plate 16. 01, the magnetic rod 14 configured for each of the iron removal chambers 101 can be assembled on the cover plate 12 in a liftable manner, and a suspension beam 13 is provided on the top of the cover plate 12. Each iron removal chamber 101 is equipped with a plurality of magnetic rods 14 (four in this embodiment) to form a magnetic rod group. The tops of the magnetic rods 14 of the same magnetic rod group are fixed by a connecting plate 18, and the connecting plate 18 has a hook 15. When the magnetic rod 14 is lifted, it is hung on the suspension beam 13 by the hook 15 and remains in a suspended state. More specifically, a sleeve is fixed on the cover plate 12, and the magnetic rod 14 can be movably inserted into the sleeve. Iron particles will be adsorbed on the sleeve by the magnetic rod 14. When the magnetic rod 14 is lifted, the iron particles on the sleeve lose the attraction of the magnetic field and fall off, so that they can be cleaned uniformly. A tension spring 17 is provided between the connecting plate 18 and the cover plate 12, and the tension spring 17 applies a downward pulling force to the magnetic rod 14 to keep the magnetic rod 14 in the extended position during production work. Furthermore, in order to prevent the magnetic rod 14 from being directly exposed to the air and being adsorbed by dust when it is lifted, in this embodiment, a protective sleeve (such as a rubber sleeve) is fixedly provided on the periphery of the magnetic rod 14. It can be understood that the protective sleeve is a thin protective layer fixedly sleeved on the periphery of the magnetic rod 14. More specifically, each iron removal chamber 101 is equipped with four magnetic rods 14 distributed in a diamond shape, and the spacing between the four magnetic rods 14 meets the overlapping requirements of the magnetic field, ensuring that the magnetic field distribution is not less than 8000 Gauss (GS); at the same time, the four magnetic rods 14 distributed in a diamond shape can contact the slurry more evenly, achieving a better iron removal effect. Of course, this is not limited to other embodiments.

[0031] Each pipe group has a feed channel, a discharge channel, an air inlet channel, a return channel, a water inlet channel, and a sewage channel. Each pipe group is also equipped with a switch valve for controlling the opening and closing of each of these channels. The corresponding channels are opened and closed by operating a specific switch valve. The feed channel and return channel are used to connect to the slurry raw material bin, the discharge channel is used to connect to the slurry finished product bin, the air inlet channel is used to connect to the air source device, and the water inlet channel is used to connect to the water source device.

[0032] In this embodiment, a slurry iron removal operation method based on the above-mentioned slurry iron remover is also provided. Before production, the feed channel and return channel of the pipeline group are connected to the slurry raw material warehouse, the discharge channel is connected to the slurry finished product warehouse, the air inlet channel is connected to the air source device, and the water inlet channel is connected to the water source device.

[0033] In the production state, the magnetic bars 14 of the two iron removal chambers 101 are lowered, the feed channels and the discharge channels of the two sets of pipe groups are opened, and the water inlet channels, air inlet channels, return channels and sewage discharge channels of the two sets of pipe groups are closed. The slurry in the slurry raw material bin enters the two iron removal chambers at the same time from the feed channel. The two iron removal chambers perform iron removal operations independently. After iron removal, the slurry is output from the discharge channel to the slurry finished product bin;

[0034] During cleaning, the first iron removal chamber 101 is kept in production state, and the operation process of the second iron removal chamber 101 is as follows: S1, the feed channel and the discharge channel of the pipeline group of the second iron removal chamber 101 are closed, S2, the return channel and the air inlet channel of the pipeline group of the second iron removal chamber are opened, and the air source device blows air into the second iron removal chamber 101 through the air inlet channel to return the slurry in the second iron removal chamber 101 from the return channel to the slurry raw material bin until the return is completed; S3, the return channel and the air inlet channel are closed, and the magnetic rod 14 of the second iron removal chamber 101 is lifted; S4, the water inlet channel of the pipeline group of the second iron removal chamber 101 is opened, and the water source device outputs the cleaning water source to the second iron removal chamber through the water inlet channel to clean the second iron removal chamber 101. After cleaning is completed, the sewage channel connected to the second iron removal chamber 101 is opened, and the sewage is discharged from the sewage channel;

[0035] After the cleaning of the second deironing chamber 101 is completed, the second deironing chamber 101 is switched to the production state, and the above-mentioned cleaning operations S1-S4 are performed on the first deironing chamber 101; that is, the feed channel and the discharge channel of the pipeline group of the first deironing chamber 101 are closed, S2, the return channel and the air inlet channel of the pipeline group of the first deironing chamber 101 are opened, and the air source device blows air into the first deironing chamber 101 through the air inlet channel to remove the iron in the first deironing chamber 101. The slurry flows back from the return channel to the slurry raw material bin until the return is completed; S3, close the return channel and the air inlet channel, and lift the magnetic rod 14 of the first iron removal chamber 101; S4, open the water inlet channel of the pipeline group of the first iron removal chamber 101, and the water source device outputs the cleaning water source to the first iron removal chamber 101 through the water inlet channel to clean the first iron removal chamber 101. After cleaning is completed, open the sewage channel connected to the first iron removal chamber 101, and the sewage is discharged from the sewage channel.

[0036] In this way, uninterrupted production operations are achieved on a single iron remover. For example, when the total capacity is the same, when both iron removal chambers 101 are performing production operations, their output is equivalent to the operating output of the iron remover in one existing chamber. When one iron removal chamber 101 is cleaned and the other iron removal chamber 101 maintains production operations, its output is equivalent to half of the operating output of the iron remover in one existing chamber. Production can be continued, and the progress of the entire production link can be effectively guaranteed. No additional space is taken up, and the cost is effectively controlled. That is, compared with the prior art where two complete iron removers are used for alternating production, the present application can at least save the cost of one iron remover tank body 10.

[0037] At the same time, each set of pipeline groups also includes an air inlet channel and a return channel. The return channel is used to connect the slurry raw material bin. Before cleaning, gas can be blown into the air inlet channel to return the slurry in the iron removal chamber 101 from the return channel to the slurry raw material bin to ensure full recovery of the remaining slurry.

[0038] Furthermore, in this embodiment, each iron removal chamber 101 is configured with a first interface, a second interface and a third interface, and each group of pipeline groups includes an inlet pipeline unit 20, a discharge pipeline unit 30 and a discharge pipeline unit 40, the inlet pipeline unit 20 is connected to the first interface and forms the feed channel, the air inlet channel and the water inlet channel, the discharge pipeline unit 30 is connected to the second interface and forms the discharge channel, and the discharge pipeline unit 40 is connected to the third interface and forms the return channel and the sewage discharge channel. One iron removal chamber 101 is configured with three interfaces, and two iron removal chambers 101 have only six interfaces. Such an arrangement can simplify the interface design of the iron remover tank body 10. Specifically, in this embodiment, the inlet of the iron removal chamber 101 is set at a high position, which is conducive to air recovery and cleaning, and the third interface is set at a low position, which is conducive to slurry recovery and sewage discharge.

[0039] Specifically, the inlet pipe unit 20 includes a two-inlet and one-outlet feed main pipe 21, a slurry inlet pipe 23, a feed branch pipe 25, an air inlet pipe 27 and a cleaning water inlet pipe 28; the outlet of the feed main pipe 21 is connected to the first interface of the iron removal chamber 101, and the first inlet of the feed main pipe 21 is connected to the outlet of the slurry inlet pipe 23 through a slurry switch valve 22. The slurry inlet pipe 23 and the feed main pipe 21 constitute the feed channel, the inlet of the slurry inlet pipe 23 serves as the feed port 1, and the slurry switch valve 22 serves as a switch valve for controlling the opening and closing of the feed channel. The outlet of the feed branch pipe 25 is connected to the second inlet of the feed main pipe 21 via a branch switch valve 24. The inlet of the feed branch pipe 25 is connected to the outlet of the air inlet pipe 27 and the outlet of the cleaning water inlet pipe 28, respectively, via a first three-way valve 26. The air inlet pipe 27, feed branch pipe 25, and feed main pipe 21 constitute the air inlet channel, with the inlet of the air inlet pipe 27 serving as the air inlet port 2. The cleaning water inlet pipe 28, feed branch pipe 25, and feed main pipe 21 constitute the water inlet channel, with the inlet of the cleaning water inlet pipe 28 serving as the cleaning port 3. The first three-way valve 26 and branch switch valve 24 collectively serve as on / off valves for the water inlet and air inlet channels. During production, the branch switch valve 24 is closed and the slurry switch valve 22 is opened, allowing the feed channel to connect solely to the iron removal chamber 101 for feeding. When only the air inlet channel is open, the slurry switch valve 22 is closed, the first three-way valve 26 is controlled to connect the air inlet pipe 27 and the feed branch pipe 25, and the connection between the cleaning water inlet pipe 28 and the feed branch pipe 25 is closed; at the same time, the branch switch valve 24 is opened to open the air inlet channel alone. When only the water inlet channel is open, the slurry switch valve 22 is closed, the first three-way valve 26 is controlled to connect the cleaning water inlet pipe 28 and the feed branch pipe 25, and the connection between the air inlet pipe 27 and the feed branch pipe 25 is closed; at the same time, the branch switch valve 24 is opened to open the water inlet channel alone. The above-mentioned configuration of the inlet pipe unit 20 can greatly simplify the pipeline design, realizing the functions of three channels with a relatively simple pipeline, and has a good effect.

[0040] Furthermore, the slurry inlet pipe 23 is a one-inlet, two-outlet tee pipe, and the two outlets of the slurry inlet pipe 23 are respectively connected to the slurry switch valves 22 on the inlet pipe units 20 of the two pipe groups. The inlet of the slurry inlet pipe 23 serves as the feed port 1 of the two pipe groups. In this way, the slurry raw material bin can be connected externally through a single feed port 1 to simultaneously supply material to the two iron removal chambers 101, further simplifying the pipeline structure. Of course, in other embodiments, the slurry inlet pipe 23 of each inlet pipe unit 20 can also be an independent single-channel pipe.

[0041] The feed branch pipe 25 is a three-way pipe with one inlet and two outlets. The two outlets of the feed branch pipe 25 are respectively connected to the branch switch valves 24 on the inlet pipe units 20 of the two pipe groups. The inlet of the feed branch pipe 25 is connected to the outlet of the air inlet pipe 27 and the outlet of the cleaning water inlet pipe 28 respectively through the first three-way valve 26. The inlet of the air inlet pipe 27 also serves as the air inlet 2 of the two pipe groups, and the inlet of the cleaning water inlet pipe 28 also serves as the cleaning port 3 of the two pipe groups. In other words, the two pipe groups can be realized with only one first three-way valve 26, one cleaning water inlet pipe 28, and one air inlet pipe 27. The on-off control is controlled by the branch switch valve 24 of each pipe group. Of course, in other embodiments, the air inlet channel and water inlet channel of each pipe group can also be independent.

[0042] Furthermore, the discharge pipe unit 30 includes a first discharge pipe section 31 and a second discharge pipe section 33, the inlet of the first discharge pipe section 31 is connected to the second interface of the iron removal chamber 101, and the outlet of the first discharge pipe section 31 is connected to the inlet of the second discharge pipe section 33 through a discharge switching valve 32. The first discharge pipe section 31 and the second discharge pipe section 33 constitute the discharge channel, and the discharge switching valve 32 serves as a switching valve for controlling the opening and closing of the discharge channel. The single outlet of the second discharge pipe section 33 serves as a discharge port 4, which is used to be connected to an external slurry finished product warehouse.

[0043] More specifically, the second discharge pipe section 33 is a two-inlet, one-outlet tee pipe. The two inlets of the second discharge pipe section 33 are connected to the discharge on-off valves 32 on the discharge pipe units 30 of the two pipe groups, respectively. The single inlet of the second discharge pipe section 33 serves as the discharge port 4 of the two pipe groups. This single discharge port 4 is connected to the finished slurry bin, further simplifying the piping structure. Of course, in other embodiments, the second discharge pipe section 33 of each discharge pipe unit 30 can also be an independent single-channel pipe.

[0044] Furthermore, the discharge pipe unit 40 includes a discharge main pipe 41, a return pipe 43 and a sewage pipe 44. The inlet of the discharge main pipe 41 is connected to the third interface of the iron removal chamber 101, and the outlet of the discharge main pipe 41 is connected to a second three-way valve 42. The first outlet of the second three-way valve 42 is connected to the inlet of the return pipe 43. The return pipe 43 and the discharge main pipe 41 constitute the return channel. The outlet of the return pipe 43 serves as a return port 5, which is used to connect to an external slurry raw material bin; the second outlet of the second three-way valve 42 is connected to the inlet of the sewage pipe 44. The sewage pipe 44 and the discharge main pipe 41 constitute the sewage channel, and the outlet of the sewage pipe 44 serves as a sewage port 6. The second three-way valve 42 also serves as a switch valve for controlling the opening and closing of the return channel and the sewage channel; when the return channel is opened, the second three-way valve 42 is switched to the position where the return pipe 43 and the discharge main pipe 41 are connected, so that the return pipe 43 and the discharge main pipe 41 are connected, while the discharge main pipe 41 and the sewage pipe 44 are not connected; when the sewage channel is opened, the second three-way valve 42 is switched to the position where the sewage pipe 44 and the discharge main pipe 41 are connected, so that the sewage pipe 44 and the discharge main pipe 41 are connected, while the discharge main pipe 41 and the return pipe 43 are not connected.

[0045] More specifically, in this embodiment, the sewage pipe 44 is a two-inlet, one-outlet tee pipe. The two inlets of the sewage pipe 44 are respectively connected to the second outlets of the second three-way valves 42 on the discharge pipe units 40 of the two pipe groups. The single outlet of the sewage pipe 44 serves as the sewage outlet 6 of the two pipe groups. The sewage outlet 6 is used to connect to an external sewage pipe, simplifying the pipe structure. Of course, in other embodiments, the sewage pipe 44 of each discharge pipe unit 40 can also be an independent single-channel pipe.

[0046] Furthermore, in this embodiment, the return pipe 43 of each discharge pipe unit 40 is an independent single-channel pipe. Of course, in other embodiments, the return pipe 43 can also be a three-way pipe with two inlets and one outlet like the sewage pipe 44, that is, the two inlets of the return pipe 43 are respectively connected to the first outlet of the second three-way valve 42 on the discharge pipe units 40 of the two pipe groups, and the single outlet of the return pipe 43 serves as the return port 5 of the two pipe groups, thereby simplifying the pipe structure.

[0047] Specifically, the above-mentioned pipelines and switch valves all use sanitary-grade quick-disconnect pipe fittings and valves, which can be disassembled, cleaned, and repaired quickly.

[0048] Furthermore, each of the above-mentioned switch valves adopts a manually operated valve structure. Of course, in other embodiments, electrically controlled valves, such as solenoid valves, electrically controlled three-way valves, etc., can also be used to achieve automatic operation controlled by the control system.

This is equivalent to transferring the air inlet channel and water inlet channel in the first embodiment to the discharge pipe unit 30. The specific connection method is as follows:

[0051] The inlet pipe unit 20 only includes a feed main pipe 21 and a slurry inlet pipe 23. The feed main pipe 21 is a straight-through pipe with one inlet and one outlet.

[0052] The discharge pipe unit 30 includes a first pipe section 34, a second pipe section 35, a feed branch pipe 25, an air inlet pipe 27 and a cleaning water inlet pipe 28. The first pipe section 34 is a three-way pipe. The first connection port of the first pipe section 34 is connected to the second interface of the iron removal chamber 101. The second connection port of the first pipe section 34 is connected to the inlet of the second pipe section 33 through the discharge switch valve 32. The first pipe section 34 and the second pipe section 35 constitute the discharge channel. The discharge switch valve 32 serves as a switch valve for controlling the opening and closing of the discharge channel. The single outlet of the second pipe section 35 serves as the discharge port 4, which is used to be externally connected to the slurry finished product warehouse.

[0053] The outlet of the feed branch pipe 25 is connected to the third connection port of the first pipe section 34 via the branch switch valve 24. The inlet of the feed branch pipe 25 is connected to the outlet of the air inlet pipe 27 and the outlet of the cleaning water inlet pipe 28, respectively, via the first three-way valve 26. The air inlet pipe 27, feed branch pipe 25, and first pipe section 34 constitute the air inlet channel, with the inlet of the air inlet pipe 27 serving as the air inlet port 2. The cleaning water inlet pipe 28, feed branch pipe 25, and first pipe section 34 constitute the water inlet channel, with the inlet of the cleaning water inlet pipe 28 serving as the cleaning port 3. The first three-way valve 26 and branch switch valve 24 jointly serve as on / off valves for the water inlet and air inlet channels. During production, the branch switch valve 24 is closed and the discharge switch valve 32 is opened, allowing the discharge channel to connect solely to the iron removal chamber 101 for discharge. When only the air inlet channel is open, the discharge switching valve 32 is closed, the first three-way valve 26 is controlled to connect the air inlet pipe 27 and the feed branch pipe 25, and the connection between the cleaning water inlet pipe 28 and the feed branch pipe 25 is closed; at the same time, the branch switching valve 24 is opened to open the air inlet channel alone. When only the water inlet channel is open, the discharge switching valve 32 is closed, the first three-way valve 26 is controlled to connect the cleaning water inlet pipe 28 and the feed branch pipe 25, and the connection between the air inlet pipe 27 and the feed branch pipe 25 is closed; at the same time, the branch switching valve 24 is opened to open the water inlet channel alone. The above-mentioned configuration of the discharge pipe unit 30 can greatly simplify the pipeline design, realizing the functions of three channels with a relatively simple pipeline, and has a good effect.

[0054] Furthermore, the feed branch pipe 25 is a three-way pipe with one inlet and two outlets, and the two outlets of the feed branch pipe 25 are respectively connected to the branch switch valves 24 on the inlet pipe units 20 of the two pipe groups; the inlet of the feed branch pipe 25 is respectively connected to the outlet of the air intake pipe 27 and the outlet of the cleaning water inlet pipe 28 through the first three-way valve 26, and the inlet of the air intake pipe 27 serves as the air inlet 2 of the two pipe groups, and the inlet of the cleaning water inlet pipe 28 serves as the cleaning port 3 of the two pipe groups; that is, the two pipe groups can be achieved with only one first three-way valve 26, one cleaning water inlet pipe 28 and one air intake pipe 27; and the on-off is controlled by the branch switch valve 24 of each pipe group.

[0055] The second pipe section 35 is a two-inlet and one-outlet tee pipe, and the two inlets of the second pipe section 35 are respectively connected to the discharge switching valves 32 on the discharge pipe units 30 of the two pipe groups. The single inlet of the second pipe section 35 serves as the discharge port 4 of the two pipe groups; the slurry finished product warehouse is externally connected through the single discharge port 4, further simplifying the pipeline structure.

[0056] Specifically, in this embodiment, the structure of the discharge pipe unit 40 is based on the structure of the first embodiment and adds a discharge switching valve 45, that is, the second outlet of the second three-way valve 42 is connected to the discharge switching valve 45, and the inlet of the sewage pipe 44 is connected through the discharge switching valve 45. The second three-way valve 42 and the discharge switching valve 45 together serve as the switching valve of the sewage channel.

[0057] More specifically, in this embodiment, the first interface connected to the inlet pipe unit 20 is lower than the second interface connected to the discharge pipe unit 30 . This arrangement can ensure that the slurry can be more fully iron-removed in the iron-removing chamber 101 .

[0058] This embodiment also provides a slurry iron removal method based on the slurry iron remover provided in this embodiment. This method is identical to the method provided in Example 1, except that since the air inlet and water inlet channels are relocated to the discharge pipe unit, the specific operations for opening the air inlet, water inlet, and discharge channels are different. Specifically, the branch switch valve 24 is closed, and the discharge switch valve 32 is opened, allowing the discharge channel to connect solely to the iron removal chamber 101 to achieve discharge. When only the air inlet channel is opened, the discharge switch valve 32 is closed, and the first three-way valve 26 is controlled to connect the air inlet pipe 27 and the feed branch pipe 25, while the connection between the cleaning water inlet pipe 28 and the feed branch pipe 25 is closed. Simultaneously, the branch switch valve 24 is opened, allowing the air inlet channel to be opened alone. When only the water inlet channel is opened, the discharge switch valve 32 is closed, and the first three-way valve 26 is controlled to connect the cleaning water inlet pipe 28 and the feed branch pipe 25, while the connection between the air inlet pipe 27 and the feed branch pipe 25 is closed. Simultaneously, the branch switch valve 24 is opened, allowing the water inlet channel to be opened alone.

[0059] The solution of the above embodiment is one of the more preferred solutions for implementing the present application. Of course, it is not limited to this in other embodiments. For example, the above-mentioned feed channel, discharge channel, air intake channel, return channel, water intake channel and sewage discharge channel can also be implemented separately using independent pipeline systems. However, compared with the solution of the present application, its pipeline structure is complex and not easy to maintain.

[0060] Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the present invention.
