[0039] The utility model provides a magnetic rod cleaning device, which comprises a magnetic rod 10, a nozzle 20 and a scraper 30. A first pipe 11 is arranged in the magnetic rod 10, an inlet 12 is arranged at the top of the magnetic rod 10, and an outlet 13 is arranged at the bottom, and the first pipe 11 is communicated with the inlet 12 and the outlet 13 respectively; the nozzle 20 is arranged at the bottom of the magnetic rod 10, and a blowing port 21 is provided at the bottom of the nozzle 20, and a second pipe 22 is arranged in the nozzle 20, one end of the second pipe 22 is communicated with the outlet 13, and the other end is communicated with the blowing port; the scraper 30 is movably arranged on the magnetic rod 10, and the scraper 30 is used to collect impurities adsorbed on the magnetic rod 10 to the nozzle 20; wherein, the nozzle 20 is used to blow air to the scraper 30 to clean the impurities.

[0040] Please refer to Figure 1 In one embodiment, the magnetic rod 10 may be a permanent magnet or an electromagnet. The magnetic rod 10 is a hollow structure. The hollow structure is preferably arranged at the axial center of the magnetic rod 10 to form a linear first pipe 11.

[0041] The inlet 12 and the outlet 13 are respectively disposed at the upper and lower ends of the magnetic rod 10 and are connected to the first pipe 11 .

[0042] In this embodiment, the inlet 12 can be connected to an external air source, such as a blower, etc. The air source is connected to the inlet 12 through a pipeline. The inlet 12 can also be connected to an external water source, such as a clean water tank, a cleaning solvent tank, etc. The water source is connected to the inlet 12 through a pipeline.

[0043] The gas or cleaning solvent passes through the inlet 12 , the first pipe 11 , the outlet 13 , the second pipe 22 , and flows out from the blowing port 21 .

[0044] During cleaning, the scraper head 30 is moved to the top of the magnetic rod 10. When the magnetic rod 10 is full of impurities, the scraper head 30 is driven down to the position corresponding to the nozzle 20, so that the impurities on the magnetic rod 10 are collected at the position of the nozzle 20. The impurities attached to the scraper head 30 are cleaned from the scraper head 30 by the gas blown out from the blowing port 21 or the outflowing cleaning solvent, so that the scraper head 30 is thoroughly cleaned.

[0045] In this embodiment, a linearly installed first pipe 11 is used to form a larger flow area, reduce the risk of blockage in the first pipe 11, and reduce the pressure loss of the gas source and the water source, thereby providing a larger purge gas flow or a larger cleaning solvent flow.

[0046] At the same time, the hollow structure of the magnetic rod 10 can also reduce the weight of the magnetic rod 10 without affecting the magnetic field strength and adsorption capacity of the surface of the magnetic rod 10, while reducing the design cost of the magnetic rod 10 and even the entire machine.

[0047] In one embodiment, the scraper head 30 and the nozzle 20 can be made of non-magnetic materials. When the scraper head 30 is lowered to the position corresponding to the nozzle 20, the top of the scraper head 30 is flush with the top of the nozzle 20. Therefore, when the scraper head 30 collects impurities at the position of the nozzle 20, the impurities lose their magnetism and fall off. At the same time, the adsorption force of the residual impurities on the scraper head 30 and the nozzle 20 is reduced, the cleaning effect of the nozzle 20 when blowing air is improved, and the impurities are more easily removed from the scraper head 30 and the nozzle 20.

[0048] In one embodiment, the scraper head 30 and the magnetic rod 10 are driven independently of each other, the magnetic rod 10 is driven to rise and fall by the first driving member, and the scraper head 30 is driven to rise and fall by the second driving member 50. The first driving member and the second driving member 50 can both be cylinders or linear modules.

[0049] By independently driving the lifting, the magnetic rod 10 can be purged after it rises. It can be understood that the first driving member drives the magnetic rod 10 to descend so that the magnetic rod 10 extends into the liquid storage tank 60 to absorb impurities in the slurry, and drives the magnetic rod 10 to rise to take the impurities away from the liquid storage tank 60, thereby filtering the slurry in the liquid storage tank 60.

[0050] In this embodiment, the lifting and lowering are independently controlled so that the movement of the scraper head 30 and the blowing movement of the nozzle 20 are unrelated, and the magnetic rod 10 can be blown as needed, especially when the magnetic rod 10 is just lifted, the blowing movement of the nozzle 20 is increased to reduce the probability of the slurry in the liquid storage tank 60 adhering to the magnetic rod 10.

[0051] In addition, in one embodiment, please refer to Figure 3 In order to improve the cleaning efficiency, the number of magnetic rods 10 can be set to multiple, and multiple magnetic rods 10 can be simultaneously extended into the same liquid storage tank 60, or respectively extended into different liquid storage tanks 60 for filtering. The multiple magnetic rods 10 are connected by connecting rods, and the scraping heads 30 on the corresponding multiple magnetic rods 10 are connected by scraping plates 40.

[0052] The scraper 40 has a plurality of mounting holes, and each magnetic rod 10 passes through a corresponding mounting hole. The scraper 40 is mounted on the top of the scraper head 30 and connected to the scraper head 30.

[0053] In this embodiment, the first driving member is connected to the connecting rod, so that the first driving member drives multiple magnetic rods 10 to rise and fall synchronously. Similarly, the second driving member 50 is connected to the scraper 40, so that the second driving member 50 drives multiple scraper heads 30 to rise and fall synchronously.

[0054] The technical solution of the utility model uses the scraper head 30 to collect the impurities adsorbed on the magnetic rod 10 to the position of the nozzle 20 at the bottom. The airflow is ejected from the blowing port 21 of the nozzle 20 and blows away the impurities collected in the scraper head 30. Thus, the impurities on the scraper head 30 are thoroughly cleaned, impurity residue is avoided, and the cleaning efficiency is improved.

[0055] In one embodiment, please refer to Figure 1 The scraper head 30 includes a mounting seat 31 and a guide portion 32. The mounting seat 31 can be movably set on the magnetic rod 10; one end of the guide portion 32 is connected to the edge of the mounting seat 31, and the other end extends to the bottom of the magnetic rod 10. When the scraper head 30 moves to a position corresponding to the nozzle 20, the guide portion 32 wraps around the blowing port 21.

[0056] In order to improve the connection strength between the mounting seat 31 and the guide portion 32 , the mounting seat 31 and the guide portion 32 may be integrally formed.

[0057] The mounting seat 31 has a through hole, and the magnetic rod 10 is inserted into the through hole. The guide portion 32 is arranged along the edge of the mounting seat 31 and extends downward. When the scraper head 30 is lowered to a position corresponding to the position of the nozzle 20, the mounting seat 31 is flush with the top of the nozzle, and the blowing port 21 is located at the bottom of the nozzle, thereby preventing the scraper head 30 from blocking the blowing port 21.

[0058] The guide portion 32 surrounds the blowing port 21 . When the blowing port 21 is blowing, impurities fall downward along the side wall of the guide portion 32 , thereby preventing impurities from splashing, improving the convenience of collecting impurities, and avoiding secondary pollution.

[0059] In one embodiment, the blowing port 21 is disposed on the side wall of the nozzle 20, and the blowing port 21 is disposed toward the guide portion 32. Thus, when the airflow is blown out from the blowing port 21, the airflow can directly blow the surrounding guide portion 32, thereby improving the cleaning effect on the guide portion 32.

[0060] In one embodiment, please refer to Figure 1 and Figure 2 The second pipeline 22 includes a first pipeline 221 and a second pipeline 222. One end of the first pipeline 221 is connected to the first pipeline 11, and the other end extends to the bottom of the nozzle; one end of the second pipeline 222 is connected to the bottom of the first pipeline 221, and the other end is connected to the blowing port 21. There are multiple second pipelines 222, and the multiple second pipelines 222 are arranged at intervals along the circumference of the first pipeline 221.

[0061] The second pipeline 222 is arranged around the first pipeline 221. A plurality of blowing ports 21 are arranged on the side wall of the nozzle 20. The plurality of blowing ports 21 are arranged at intervals along the circumferential direction of the side wall of the nozzle 20. Each second pipeline 222 is connected to a corresponding blowing port 21.

[0062] The airflow enters from the inlet 12, flows into the first pipeline 221 along the first pipeline 11, and is blown out from multiple different second pipelines 222. The gas reaches the bottom of the magnetic rod 10 in the vertical direction and is ejected in all directions at the nozzle 20, further reducing the gas pressure loss.

[0063] Furthermore, by spraying in all directions, air can be blown around the guide portion 32 at the same time, further improving the cleaning effect.

[0064] In one embodiment, a clamping groove 23 is provided at the top of the nozzle 20 , and a clamping block 14 is provided at the bottom of the magnetic rod 10 . The clamping block 14 is disposed in the clamping groove 23 .

[0065] The outlet 13 is arranged at the bottom of the clamping block 14, the top of the clamping groove 23 has an air hole, the top of the first pipeline 221 is connected to the air hole, the bottom of the clamping groove 23 is closed, one end of the second pipeline 222 is connected to the bottom of the first pipeline 221, and the other end extends to the side wall of the nozzle 20 and is connected to the blowing port 21. When the clamping block 14 and the clamping groove 23 are connected, the air hole and the outlet 13 are connected, thereby forming a conductive pipeline.

[0066] In this embodiment, the nozzle 20 and the magnetic rod 10 are limited by the cooperation of the clamping block 14 and the clamping groove 23, so as to avoid the position deviation of the nozzle 20 during the blowing process and improve the cleaning stability.

[0067] In addition, in order to solve the above problems, the utility model also proposes a liquid filtering device, please refer to Figure 4 The liquid filtering equipment includes a liquid storage tank 60 and a magnetic rod cleaning device as described above; the magnetic rod 10 can be raised and lowered in the liquid storage tank 60. After the slurry is transported to the liquid storage tank 60 by pumping or the like, the slurry is filtered by the magnetic rod 10 to remove impurities in the slurry.

[0068] The technical solution of the utility model uses the scraper head 30 to collect the impurities adsorbed on the magnetic rod 10 to the position of the nozzle 20 at the bottom. The airflow is ejected from the blowing port 21 of the nozzle 20 and blows away the impurities collected in the scraper head 30. Thus, the impurities on the scraper head 30 are thoroughly cleaned, impurity residue is avoided, and the cleaning efficiency is improved.
