Description

Technical Field

[0001] The invention relates to the technical field of iron removal and filtration, in particular to an electromagnetic iron removal filter. Background Art

[0002] Electromagnetic iron removal filter, also known as electromagnetic filter, can remove tiny iron powder in liquid. The liquid raw material passes through the magnetized electromagnetic filter, so that the filler inside it adsorbs the tiny iron powder in the liquid, thereby achieving the purpose of filtering.

[0003] In factory production, when water is discharged, it generally contains a lot of iron elements, and then it is necessary to use an electromagnetic iron removal filter to remove the iron elements in the liquid to meet the discharge standards. In the prior art, a sleeve is generally set on the outer surface of a magnetic rod so that the magnetic force of the magnetic rod itself penetrates the sleeve, and then the liquid passes through the outer surface of the sleeve, so that the iron elements in the liquid can be adsorbed to achieve the purpose of filtering. However, when cleaning the iron elements adsorbed on the surface of the sleeve, it is necessary to pull the magnetic rod out of the sleeve so that the iron elements lose their adsorption force, and then inject clean water into the electromagnetic iron removal filter, and block the water outlet. Under the impact of clean water, the iron elements are driven to separate from the outer surface of the sleeve, and then the sewage valve is opened to drive the iron elements to flow out with clean water. However, the sewage containing iron elements is easily mixed with other impurities. If there are sticky impurities adhering to the surface of the sleeve, it is difficult to clean them with clean water, and it is easy for the iron elements to form accumulation and hardening on the outer surface of the sleeve with other impurities, so that the magnetic resistance of the sleeve to the magnetic rod is increased, thereby affecting the filtration of iron elements in the liquid.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-8 , an electromagnetic iron removal filter, comprising a cylinder 1:

[0044] The cylinder 1 is provided with a filter assembly 2, a fixing assembly 3, a first driving assembly 4, a cleaning assembly 5, a second driving assembly 6, a sealing assembly 7 and a sewage discharge assembly 8 respectively;

[0045] The outer surface of the filter assembly 2 is fixedly mounted inside the cylinder 1, so that the filter assembly 2 can adsorb the iron element in the liquid inside the cylinder 1;

[0046] The bottom end of the fixing component 3 is arranged to fit with the top end of the filter component 2, so that the fixing component 3 fixes the filter component 2;

[0047] The output end of the first driving component 4 is connected to the inner thread of the cleaning component 5, so that the first driving component 4 drives the cleaning component 5 to operate, so that the cleaning component 5 cleans the surface of the filter component 2;

[0048] The telescopic end of the second driving component 6 is fixedly connected to the bottom end of the sewage discharge component 8, so that the second driving component 6 drives the sewage discharge component 8 to operate, so that the sewage discharge component 8 discharges the iron elements inside the cleaning component 5;

[0049] The interior of the sealing component 7 is sealed with the outer surface of the sewage discharge component 8 so that the sealing component 7 separates the sewage discharge component 8 from the interior of the cylinder 1 .

As the cleaning assembly 5 continues to move, its bottom end can fit with the inside of the sealing assembly 7, and its outer surface can be sleeved on the outer surface of the sewage discharge assembly 8, so that the internal space of the cleaning assembly 5 is separated from the internal space of the cylinder 1, and then the second drive assembly 6 is started to drive the extension The sewage discharge component 8 fixedly installed at the contracted end moves upward, so that the interior of the sewage discharge component 8 is connected with the sealing component 7 and the interior of the cleaning component 5, so that the iron element inside the cleaning component 5 enters the interior of the sewage discharge component 8 with the flow of liquid. Since the outer surface of the second drive component 6 is sealed and sleeved with the inner wall of the cylinder 1, the liquid and iron element mixture entering the sewage discharge component 8 falls on the top of the second drive component 6 for temporary storage, and then the second drive component 6 is started again to drive the sewage discharge component 8 to move downward for reset, and the first drive component 4 is started to drive the cleaning component 5 to move upward for reset, and then the above steps are repeated reciprocally to achieve the purpose of cleaning the outer surface of the filter component 2 during the filtration process.

[0051] The present invention starts the first driving component 4 to drive the cleaning component 5 threadedly connected to the output end to move downward, so that it can scrape off the iron elements adsorbed on the outer surface of the filter component 2 and concentrate them inside the cleaning component 5. As the cleaning component 5 continues to move, its bottom end can fit with the inside of the sealing component 7, and its outer surface can be sleeved on the outer surface of the sewage discharge component 8, so that the internal space of the cleaning component 5 is separated from the internal space of the cylinder 1. Then, the second driving component 6 is started to drive the sewage discharge component 8 fixedly installed at the telescopic end to move upward, so that the interior of the sewage discharge component 8 cooperates with the sealing component 7 to communicate with the interior of the cleaning component 5, so that the iron elements inside the cleaning component 5 enter the interior of the sewage discharge component 8 with the flow of liquid. Since the outer surface of the second driving component 6 is sealed and sleeved with the inner wall of the cylinder 1, the liquid and iron element mixture entering the sewage discharge component 8 falls on the top of the second driving component 6 for temporary storage. By reversing the first driving component 4 and resetting the second driving component 6, and repeating the above steps, the outer surface of the filter component can be cleaned in real time to avoid accumulation on the outer surface of the filter component 2.

[0053] The sleeve 202 and the magnetic rod 203 are provided in multiple groups in a circular shape and in equal numbers, so as to adsorb and filter the iron elements in the flowing liquid inside the cylinder 1, thereby ensuring the filtering effect.

[0054] Further, for the above-mentioned fixing assembly 3, the fixing assembly 3 includes a rotating seat 301, the top of the rotating seat 301 is fixedly connected to the bottom of the cylinder 1, a threaded cylinder 302 is rotatably arranged inside the rotating seat 301, a screw rod 303 is threadedly connected inside the threaded cylinder 302, and a rotating handle 304 is fixedly connected to the top of the screw rod 303;

[0056] By flipping the threaded barrel 302, it can make a circular motion with the rotating seat 301 as the center, thereby driving the screw rod 303 connected to its internal thread to make a circular motion, and flip it to the top of the mounting plate 204, and rotate the handle 304 to drive the screw rod 303 fixedly connected at the bottom to rotate. When the screw rod 303 rotates, it can cooperate with the threaded barrel 302 to move downward, and the pressure rod 305 slidably set on the outer surface of the screw rod 303 can be moved downward, so that its outer surface is pressed and fixed to the top of the mounting plate 204.

[0057] Furthermore, for the above-mentioned first driving component 4, the first driving component 4 includes a motor 401, the top end of the motor 401 is fixedly installed with the bottom end of the cylinder 1, and the output end of the motor 401 is fixedly installed with a threaded rod 402, and the threaded surface of the threaded rod 402 is connected to the internal thread of the cleaning component 5.

[0058] The threaded rod 402 fixedly mounted at the output end is driven to rotate by starting the motor 401 . When the threaded rod 402 rotates, it can drive the cleaning component 5 threadedly connected to its threaded surface to operate, so as to provide stable power for the cleaning component 5 .

[0059] Furthermore, for the above-mentioned cleaning component 5, the cleaning component 5 includes a threaded seat 501, the interior of the threaded seat 501 is threadedly connected to the threaded surface of the threaded rod 402, the top of the threaded seat 501 is fixedly installed with a connecting frame 502, the bottom end of the connecting frame 502 is fixedly connected with a cleaning bucket 503, and the interior of the cleaning bucket 503 is slidably arranged with the outer surface of the sleeve 202.

[0060] By starting the motor 401, the threaded rod 402 fixedly installed at the output end is driven to rotate. When the threaded rod 402 rotates, it can drive the threaded seat 501 threadedly connected to its threaded surface to move up and down. When the threaded seat 501 moves up and down, it can drive the connecting frame 502 fixedly installed at its top to move. When the connecting frame 502 moves, it can drive the cleaning bucket 503 fixedly connected at its bottom to move. Since the interior of the cleaning bucket 503 fits the outer surface of the sleeve 202, the cleaning bucket 503 can clean the iron elements adsorbed on the outer surface of the sleeve 202 during the movement.

[0061] Furthermore, for the above-mentioned second driving component 6, the second driving component 6 includes an electric push rod 601, the top end of the electric push rod 601 is fixedly installed with the bottom end of the cylinder 1, the telescopic end of the electric push rod 601 is fixedly installed with a guide plate 602, and the top end of the guide plate 602 is fixedly connected with the bottom end of the sewage discharge component 8.

[0062] By starting the electric push rod 601 to drive the guide plate 602 fixedly installed at the telescopic end to move up and down, the sewage discharge component 8 fixedly connected to its top can be driven to move, and then the opening and closing of the sewage discharge component 8 can be controlled, which is relatively convenient.

[0063] Further, for the sealing assembly 7, the sealing assembly 7 includes a sealing disc 701, the outer surface of the sealing disc 701 is fixedly connected to the inside of the cylinder 1, and a connecting groove 702 is provided at the top of the sealing disc 701, and the inside of the connecting groove 702 is slidably arranged with the outer surface of the cleaning bucket 503;

[0064] A drainage groove 703 is formed inside the sealing disk 701 , and a sealing ring 704 is fixedly installed inside the drainage groove 703 . The inside of the sealing ring 704 is interference-fitted with the outer surface of the sewage discharge assembly 8 .

[0065] When the cleaning bucket 503 moves with the movement of the connecting frame 502, its bottom end can be moved to the inside of the connecting groove 702, so that the iron elements concentrated inside the cleaning bucket 503 can fall into the inside of the drainage groove 703, and as the sewage discharge component 8 is opened, its interior can cooperate with the drainage groove 703 to be connected with the interior of the cleaning bucket 503, so that the iron elements can flow through the drainage groove 703 to the inside of the sewage discharge component 8, thereby facilitating the centralized treatment of the iron elements inside the cleaning bucket 503.

[0066] Furthermore, for the above-mentioned sewage discharge component 8, the sewage discharge component 8 includes a sealing cylinder 801, the outer surface of the sealing cylinder 801 is interference fit with the inside of the sealing ring 704, a sewage discharge hole 802 is opened inside the sealing cylinder 801, a sealing plug 803 is slidably arranged inside the sealing cylinder 801, a connecting rod 804 is fixedly installed at the bottom end of the sealing plug 803, and the bottom end of the connecting rod 804 is fixedly connected to the top end of the guide plate 602.

[0067] By starting the electric push rod 601 to drive the guide plate 602 fixedly installed at the telescopic end to move up and down, it can drive the connecting rod 804 fixedly connected to its top to move. When the connecting rod 804 moves, it can drive the sealing plug 803 fixedly installed at its top to move. Since the outer surface of the sealing plug 803 has an interference fit with the inner wall of the sealing cylinder 801, and multiple groups of drain holes 802 are opened inside the sealing cylinder 801, when the sealing plug 803 moves, the drain holes 802 can be opened and closed, thereby ensuring that the sealing cylinder 801 is sealed while being connected to the interior of the cylinder 1 through the drain holes 802, so as to facilitate the discharge of the iron elements inside it.

[0068] Furthermore, for the sealing disk 701 , the top end of the sealing disk 701 is fixedly connected to a limiting rod 9 , and the outer surface of the limiting rod 9 is slidably arranged with the inside of the connecting frame 502 .

[0069] There are multiple groups of limit rods 9, and all of them are slidably arranged inside the connecting frame 502, so as to limit the moving direction of the connecting frame 502 and improve the stability of the connecting frame 502 during the movement.

[0070] Furthermore, for the above-mentioned cylinder 1 , a sewage discharge pipe 10 is provided in communication with one side of the cylinder 1 , and one side of the sewage discharge pipe 10 is disposed in close contact with one side of the guide plate 602 .

[0071] Since the guide plate 602 is in the shape of an inclined disc, and the outer surface is sealed and connected to the inner wall of the cylinder 1, the iron elements and liquid flowing out through the sealing cylinder 801 can fall to the top of the guide plate 602 and be guided to the lower end of the guide plate 602. Since the lower end of the guide plate 602 corresponds to the interior of the sewage pipe 10, the iron elements and liquid at the top of the guide plate 602 can flow to the interior of the sewage pipe 10 and be discharged.

[0072] Working principle: When in use, the liquid inlet and outlet ends of the cylinder 1 are flange-connected to the external pipes respectively, so that the liquid to be filtered can pass through the inside of the cylinder 1 and pass through the outer surface of the sleeve 202, so that it can cooperate with the magnetic rod 203 to adsorb the iron elements in the liquid on the outer surface of the sleeve 202, and then start the motor 401 to drive the threaded rod 402 fixedly installed at the output end to rotate. When the threaded rod 402 rotates, it can drive the threaded seat 501 threadedly connected to its threaded surface to move up and down. When the threaded seat 501 moves up and down, it can bring The connecting frame 502 fixedly installed at the top thereof is driven to move. When the connecting frame 502 moves, the cleaning bucket 503 fixedly connected at the bottom thereof can be driven to move. Since the interior of the cleaning bucket 503 fits the outer surface of the sleeve 202, the cleaning bucket 503 can clean the iron elements adsorbed on the outer surface of the sleeve 202 during the movement. During the continuous movement, the bottom end of the cleaning bucket 503 can be sleeved in the interior of the connecting groove 702, and at the same time, the interior of the cleaning bucket 503 is sleeved in the outer surface of the sealing cylinder 801, so that the interior of the cleaning bucket 503 is The outer surface of the sealing plug 803 is interference-fitted with the inner wall of the sealing cylinder 801, and the sealing cylinder 801 is provided with a plurality of drain holes 802, so that when the sealing plug 803 moves, the drain holes 802 can be opened and closed to ensure the tightness. While sealing the sealing tube 801, it can be connected with the interior of the cylinder 1 through the drain hole 802, so as to facilitate the discharge of the iron elements inside it. Since the guide plate 602 is an inclined disc, and the outer surface is sealed and connected with the inner wall of the cylinder 1, the iron elements and liquid flowing out through the sealing tube 801 can fall to the top of the guide plate 602 and be guided to the lower end of the guide plate 602. Since the lower end of the guide plate 602 corresponds to the interior of the drain pipe 10, the iron elements and liquid at the top of the guide plate 602 can flow to the interior of the drain pipe 10 and be discharged.

Start the first drive component 4 to drive the cleaning component 5 to move downward, so that it can scrape off the iron elements adsorbed on the outer surface of the filter component 2 and concentrate them inside the cleaning component 5.

Then start the second drive component 6 to drive the sewage discharge component 8 to move upward, so that the interior of the sewage discharge component 8 is connected with the sealing component 7 and the interior of the cleaning component 5, so that the iron elements inside the cleaning component 5 enter the interior of the sewage discharge component 8 with the flow of liquid. Since the outer surface of the second drive component 6 is sealed and sleeved with the inner wall of the cylinder 1, the liquid and iron element mixture entering the sewage discharge component 8 falls on the top of the second drive component 6 for temporary storage. By reversing the first drive component 4 and resetting the second drive component 6, and repeating the above steps, the outer surface of the filter component can be cleaned in real time to avoid its accumulation on the outer surface of the filter component 2.

By starting the motor 401 to drive the threaded rod 402 to rotate, the threaded rod 402 can drive the threaded seat 501 to move up and down, the threaded seat 501 can drive the connecting frame 502 to move, and the connecting frame 502 can drive the cleaning bucket 503 to move. Since the interior of the cleaning bucket 503 fits the outer surface of the sleeve 202, the cleaning bucket 503 can clean the iron elements adsorbed on the outer surface of the sleeve 202 during the movement;

By starting the electric push rod 601 to drive the guide plate 602 to move up and down, the connecting rod 804 can be driven to move, and the connecting rod 804 can drive the sealing plug 803 to move. Since the outer surface of the sealing plug 803 is interference fit with the inner wall of the sealing cylinder 801, and multiple groups of drain holes 802 are opened inside the sealing cylinder 801, the sealing plug 803 can open and close the drain holes 802, ensuring that the sealing cylinder 801 is sealed while being connected with the interior of the cylinder 1 through the drain holes 802, so as to facilitate the discharge of the iron elements inside.
