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

[0029] Example 1

[0030] Reference Figure 1 , Figure 2As shown, this embodiment provides a slurry iron separator, including an iron separator tank 10. The iron separator tank 10 is divided into two independent iron removal chambers 101, each of which is equipped with a magnetic rod 14 and a set of pipes. Specifically, in this embodiment, the iron separator tank 10 includes a tank body 11 with a receiving cavity and a cover plate 12 covering the upper opening of the tank body 11. The receiving cavity of the tank body 11 is divided into two iron removal chambers 101 by a vertically arranged partition plate 16. 01. Each of the iron removal chambers 101 is equipped with a magnetic rod 14 that can be raised and lowered and mounted on the cover plate 12. The top of the cover plate 12 is provided with a suspension beam 13. Each iron removal chamber 101 is equipped with multiple magnetic rods 14 (four in this embodiment) to form a magnetic rod group. The top of the magnetic rods 14 in the same magnetic rod group is fixed by a connecting plate 18. The connecting plate 18 has a hook 15. When the magnetic rods 14 are raised, they are hung on the suspension beam 13 by the hook 15 to maintain a suspended state. More specifically, a sleeve is fixed on the cover plate 12. The magnetic rods 14 are movably inserted into the sleeve. Iron particles are attracted to the sleeve by the magnetic rods 14. When the magnetic rods 14 are raised, the iron particles on the sleeve lose the magnetic attraction 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. The tension spring 17 applies a downward pulling force to the magnetic rods 14 to maintain the inserted position of the magnetic rods 14 during production. Furthermore, to prevent the magnetic rod 14 from being directly exposed to air and attracting dust when lifted, in this embodiment, a protective sleeve (such as a rubber sleeve) is fixedly fitted around the outer periphery of the magnetic rod 14. This protective sleeve can be understood as a thin protective layer fixedly fitted around the outer periphery of the magnetic rod 14. More specifically, the four magnetic rods 14 in each iron removal chamber 101 are arranged in a rhomboid pattern, with the spacing between the four magnetic rods 14 meeting the magnetic field overlap requirements, ensuring that the magnetic field distribution is not less than 8000 Gauss (GS). Simultaneously, the rhomboid arrangement of the four magnetic rods 14 allows for relatively uniform contact with the slurry, resulting in a better iron removal effect. Of course, other embodiments are not limited to this.

[0031] Each pipeline group has a feed channel, a discharge channel, an air inlet channel, a return channel, a water inlet channel, and a sewage discharge channel. Each pipeline group is also equipped with a switch valve for controlling the opening and closing of each of these channels. Operating the specific switch valves controls the opening and closing of the corresponding channels. The feed and return channels connect to the slurry raw material silo, the discharge channel connects to the slurry finished product silo, the air inlet channel connects to the air source device, and the water inlet channel connects to the water source device.

[0032] In this embodiment, a method for removing iron from slurry 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 silo, the discharge channel is connected to the slurry finished product silo, 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 production mode, the magnetic rods 14 of the two iron removal chambers 101 are lowered, the feed channels and discharge channels of the two sets of pipelines are opened, and the water inlet channel, air inlet channel, return channel and sewage discharge channel of the two sets of pipelines are closed. The slurry in the slurry raw material silo enters the two iron removal chambers simultaneously from the feed channel. The two iron removal chambers perform iron removal operations independently. The slurry after iron removal is output from the discharge channel to the slurry finished product silo.

[0034] During cleaning, the first iron removal chamber 101 is kept in production. The operation procedure for the second iron removal chamber 101 is as follows: S1, close the feed channel and discharge channel of the pipe assembly of the second iron removal chamber 101; S2, open the return channel and air inlet channel of the pipe assembly of the second iron removal chamber; 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, close the return channel and air inlet channel, and lift the magnetic rod 14 of the second iron removal chamber 101; S4, open the water inlet channel of the pipe assembly of the second iron removal chamber 101; the water source device outputs cleaning water to the second iron removal chamber through the water inlet channel to clean the second iron removal chamber 101; after cleaning is completed, open the sewage discharge channel connected to the second iron removal chamber 101, and the sewage is discharged from the sewage discharge channel.

[0035] After cleaning the second iron removal chamber 101, switch the second iron removal chamber 101 to production mode and perform the cleaning operations S1-S4 described above on the first iron removal chamber 101; that is, close the feed channel and discharge channel of the pipe assembly of the first iron removal chamber 101, S2, open the return channel and air inlet channel of the pipe assembly of the first iron removal chamber 101, and the air source device blows air into the first iron removal chamber 101 through the air inlet channel to remove the iron from the first iron removal 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 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 discharge channel connected to the first iron removal chamber 101, and the sewage is discharged from the sewage discharge channel.

[0036] In this way, uninterrupted production can be achieved on a single iron separator. For example, when both iron separator chambers 101 are in operation with the same total capacity, their output is equivalent to that of an existing single-chamber iron separator. When one iron separator chamber 101 is being cleaned while the other iron separator chamber 101 is in operation, its output is equivalent to half of that of an existing single-chamber iron separator. Production can continue, which can effectively ensure the progress of the entire production process. Moreover, it does not occupy additional space, and the cost is effectively controlled. That is, compared with the existing technology that uses two complete iron separators to alternate production, this application can save the cost of at least one iron separator tank 10.

[0037] Meanwhile, each pipeline group 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 in through the air inlet channel to return the slurry in the iron removal chamber 101 to the slurry raw material bin, ensuring the full recovery of the remaining slurry.

[0038] Furthermore, in this embodiment, each iron removal chamber 101 is equipped with a first interface, a second interface, and a third interface. Each pipe group includes an inlet pipe unit 20, a discharge pipe unit 30, and a discharge pipe unit 40. The inlet pipe unit 20 connects to the first interface and forms the feed channel, air inlet channel, and water inlet channel. The discharge pipe unit 30 connects to the second interface and forms the discharge channel. The discharge pipe unit 40 connects to the third interface and forms the return channel and sewage discharge channel. One iron removal chamber 101 is equipped with three interfaces, and two iron removal chambers 101 have only six interfaces. This arrangement simplifies the interface design of the iron removal tank 10. Specifically, in this embodiment, the inlet of the iron removal chamber 101 is located at a high position, which is conducive to air blowing recovery and cleaning, while the third interface is located 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 via a first three-way valve 26. The air inlet pipe 27, the feed branch pipe 25, and the feed main pipe 21 constitute the air intake channel, and the inlet of the air inlet pipe 27 serves as the air inlet 2. The cleaning water inlet pipe 28, the feed branch pipe 25, and the feed main pipe 21 constitute the water intake channel, and the inlet of the cleaning water inlet pipe 28 serves as the cleaning port 3. The first three-way valve 26 and the branch switch valve 24 together serve as the switch valves for the water intake channel and the air intake channel. During production, the branch switch valve 24 is closed, and the slurry switch valve 22 is opened, allowing the feed channel to be connected solely to the iron removal chamber 101 for feeding. When only the air inlet channel is open, the slurry switch valve 22 is closed, controlling the first three-way valve 26 to connect the air inlet pipe 27 and the feed branch pipe 25, while closing the connection between the cleaning water inlet pipe 28 and the feed branch pipe 25; simultaneously, the branch switch valve 24 is opened, allowing the air inlet channel to open independently. When only the water inlet channel is open, the slurry switch valve 22 is closed, controlling the first three-way valve 26 to connect the cleaning water inlet pipe 28 and the feed branch pipe 25, while closing the connection between the air inlet pipe 27 and the feed branch pipe 25; simultaneously, the branch switch valve 24 is opened, allowing the water inlet channel to open independently. The aforementioned inlet pipe unit 20 greatly simplifies the pipeline design, achieving the functions of three channels with a relatively simple pipeline, resulting in good performance.

[0040] Furthermore, the slurry inlet pipe 23 is a three-way pipe with one inlet and two outlets. 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 sets of pipe groups. The inlet of the slurry inlet pipe 23 serves as the feed port 1 of the two sets of pipe groups. In this way, the slurry raw material silo can be connected to a single feed port 1 to supply slurry to both iron removal chambers 101 at the same time, 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 sets of 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 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 sets of pipe groups, and the inlet of the cleaning water inlet pipe 28 also serves as the cleaning outlet 3 of the two sets of pipe groups. That is, the two sets of 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, and the on / off is controlled by the branch switch valves 24 of each set of pipe groups. Of course, in other embodiments, the air inlet channel and water inlet channel of each set of pipe groups 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 switch valve 32. The first discharge pipe section 31 and the second discharge pipe section 33 constitute the discharge channel. The discharge switch valve 32 serves as a switch valve for controlling the opening and closing of the discharge channel. A single outlet of the second discharge pipe section 33 serves as a discharge port 4 for connecting to an external slurry finished product silo.

[0043] More specifically, the second discharge pipe section 33 is a two-in-one-out tee pipe. The two inlets of the second discharge pipe section 33 are respectively connected to the discharge switch valves 32 on the discharge pipe units 30 of the two sets of pipe groups, and the single inlet of the second discharge pipe section 33 serves as the discharge port 4 of the two sets of pipe groups. The slurry finished product silo is connected to the outside through the single discharge port 4, which further simplifies the pipeline 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 pipeline 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 silo. 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 discharge channel. The outlet of the sewage pipe 44 serves as a sewage outlet 6. The second three-way valve 42 also serves as a switch valve for controlling the opening and closing of the return material channel and the sewage discharge channel. When the return material channel is opened, the second three-way valve 42 is switched to the position where the return material pipe 43 and the discharge main pipe 41 are connected, thereby connecting the return material pipe 43 and the discharge main pipe 41, while the discharge main pipe 41 is not connected to the sewage discharge pipe 44. When the sewage discharge channel is opened, the second three-way valve 42 is switched to the position where the sewage discharge pipe 44 and the discharge main pipe 41 are connected, thereby connecting the sewage discharge pipe 44 and the discharge main pipe 41, while the discharge main pipe 41 is not connected to the return material pipe 43.

[0045] More specifically, in this embodiment, the drain pipe 44 is a two-inlet, one-outlet tee pipe. The two inlets of the drain pipe 44 are respectively connected to the second outlets of the second tee valves 42 on the discharge pipe units 40 of the two sets of pipe groups. The single outlet of the drain pipe 44 serves as the drain port 6 of the two sets of pipe groups, which is used to connect to external drain pipes, simplifying the pipe structure. Of course, in other embodiments, the drain 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 two-in-one-out three-way pipe 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 unit 40 of the two sets of pipe groups, and the single outlet of the return pipe 43 serves as the return port 5 of the two sets of pipe groups, thereby simplifying the pipe structure.

[0047] Specifically, the aforementioned pipes and valves all use sanitary quick-release fittings and valves, allowing for quick disassembly, cleaning, and maintenance.

[0048] Furthermore, the aforementioned switching valves adopt a manually operated valve structure. Of course, in other embodiments, electrically controlled valves, such as solenoid valves and electrically controlled three-way valves, can also be used to achieve automatic operation controlled by the control system.

[0049] Example 2

[0050] The slurry iron separator provided in this embodiment is largely the same as the slurry iron separator provided in Embodiment 1, except that: (Refer to...) Figure 3 and Figure 4 As shown, in this embodiment, the inlet pipe unit 20 only has a feeding channel, while the outlet pipe unit 30 has the aforementioned discharge channel, air inlet channel, and water inlet channel. This is equivalent to transferring the air inlet channel and water inlet channel from Embodiment 1 to the outlet pipe unit 30. The specific connection method is as follows:

[0051] The inlet pipeline unit 20 includes only a feed main pipe 21 and a slurry inlet pipe 23. The feed main pipe 21 is a straight pipe with one inlet and one outlet. The outlet of the feed main pipe 21 is connected to the first interface of the iron removal chamber 101. The 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. Furthermore, the slurry inlet pipe 23 is a three-way pipe with one inlet and two outlets. The two outlets of the slurry inlet pipe 23 are respectively connected to the slurry switch valves 22 on the inlet pipeline unit 20 of the two sets of pipelines. The inlet of the slurry inlet pipe 23 serves as the feed port 1 of the two sets of pipelines. In this way, the slurry raw material silo can be connected to a single feed port 1 to supply material to two iron removal chambers 101 at the same time, further simplifying the pipeline structure.

[0052] The discharge pipeline unit 30 includes a first pipe section 34, a second pipe section 35, an inlet branch pipe 25, an air inlet pipe 27, and a cleaning water inlet pipe 28. The first pipe section 34 is a tee 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 is a switch valve that controls the opening and closing of the discharge channel. The single outlet of the second pipe section 35 is a discharge port 4, which is used to connect to the slurry finished product silo.

[0053] The outlet of the feed branch pipe 25 is connected to the third connection port of the first pipe section 34 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 via a first three-way valve 26. The air inlet pipe 27, the feed branch pipe 25, and the first pipe section 34 constitute the air inlet channel, and the inlet of the air inlet pipe 27 serves as the air inlet 2. The cleaning water inlet pipe 28, the feed branch pipe 25, and the first pipe section 34 constitute the water inlet channel, and the inlet of the cleaning water inlet pipe 28 serves as the cleaning port 3. The first three-way valve 26 and the branch switch valve 24 together serve as the switch valves for the water inlet channel and the air inlet channel. During production, the branch switch valve 24 is closed, and the discharge switch valve 32 is opened, so that the discharge channel is connected to the iron removal chamber 101 separately to achieve discharge. When only the air inlet channel is open, the discharge switch valve 32 is closed, controlling the first three-way valve 26 to connect the air inlet pipe 27 and the feed branch pipe 25, while closing the connection between the cleaning water inlet pipe 28 and the feed branch pipe 25; simultaneously, the branch switch valve 24 is opened, allowing the air inlet channel to open independently. When only the water inlet channel is open, the discharge switch valve 32 is closed, controlling the first three-way valve 26 to connect the cleaning water inlet pipe 28 and the feed branch pipe 25, while closing the connection between the air inlet pipe 27 and the feed branch pipe 25; simultaneously, the branch switch valve 24 is opened, allowing the water inlet channel to open independently. The aforementioned discharge pipe unit 30 greatly simplifies the pipeline design, achieving the functions of three channels with a relatively simple pipeline, resulting in good performance.

[0054] Furthermore, 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 sets of 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 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 sets of pipe groups, and the inlet of the cleaning water inlet pipe 28 also serves as the cleaning outlet 3 of the two sets of pipe groups. That is, the two sets of 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 state is controlled by the branch switch valves 24 of each set of pipe groups.

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

[0056] Specifically, in this embodiment, the structure of the discharge pipeline unit 40 is based on the structure of Embodiment 1, with the addition of a discharge switch valve 45. That is, the second outlet of the second three-way valve 42 is connected to the discharge switch valve 45, and the discharge switch valve 45 is connected to the inlet of the sewage pipe 44. The second three-way valve 42 and the discharge switch valve 45 together serve as the switch valves for the sewage discharge channel.

[0057] More specifically, in this embodiment, the first interface connecting the inlet pipe unit 20 is lower than the second interface connecting the outlet pipe unit 30. This arrangement ensures that the slurry can undergo more thorough iron removal within the iron removal chamber 101.

[0058] This embodiment also provides a slurry iron removal operation method based on the slurry iron separator provided in this embodiment. This method is the same as the method provided in Embodiment 1, except that since the air inlet channel and water inlet channel are transferred to the discharge pipe unit, the specific operation when opening the air inlet channel, water inlet channel and discharge channel is different. That is: close the branch switch valve 24 and open the discharge switch valve 32, so that the discharge channel is connected to the iron removal chamber 101 alone to realize discharge. When only the air inlet channel is opened, close the discharge switch valve 32, control the first three-way valve 26 to connect the air inlet pipe 27 and the feed branch pipe 25, and close the connection between the cleaning water inlet pipe 28 and the feed branch pipe 25; at the same time, open the branch switch valve 24 to open the air inlet channel alone. When only the water inlet channel is opened, close the discharge switch valve 32, control the first three-way valve 26 to connect the cleaning water inlet pipe 28 and the feed branch pipe 25, and close the connection between the air inlet pipe 27 and the feed branch pipe 25; at the same time, open the branch switch valve 24 to open the water inlet channel alone.

[0059] The above-described embodiments are one of the preferred solutions for implementing this application. Of course, other embodiments are not limited to this. For example, the above-described feeding channel, discharging channel, air intake channel, return channel, water intake channel, and sewage discharge channel can all be implemented using independent pipeline systems. However, compared to the solution of this application, the pipeline structure is more complex and harder to maintain.

[0060] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
