Description

Technical Field

[0001] The utility model relates to the technical field of slurry demagnetizers, in particular to a slurry demagnetizer with a continuous circulation demagnetization function. Background Art

[0002] In the field of coating machines, slurry demagnetizers are an important auxiliary equipment and are widely used in slurry purification during the coating process. Their main function is to remove magnetic impurities in the slurry to avoid quality problems during the coating process, such as uneven coating, damage to coating equipment, unstable product quality, etc. With the development of the coating industry, the working speed and accuracy of coating machines are constantly improving, and slurry demagnetization technology is also constantly improving.

[0003] At present, the slurries used in coating machines are mostly mixtures of polymer materials, pigments, resins, solvents, etc. These slurries are easily affected by the external environment during production, transportation and storage, resulting in ferromagnetic impurities (such as iron filings, steel wire, iron oxides, etc.) mixing into the slurry. These impurities will not only affect the uniformity of the coating, but may also cause wear inside the coating machine and even cause damage to the equipment, ultimately affecting the stability of the coating process and the quality of the product.

[0004] In order to solve this problem, the existing technology uses different types of slurry demagnetization equipment, mainly including pipeline demagnetization tanks, tower demagnetization, demagnetization trolleys and electromagnetic demagnetization. These devices attract and remove magnetic impurities by setting a magnetic field on the slurry flow path to ensure the purity of the slurry. However, the existing demagnetization machines still have some shortcomings:

[0005] Pipeline demagnetization tank and tower demagnetization: When these devices perform one-time demagnetization of slurry, the adsorption efficiency of magnetic substances is low and the magnetic impurities in the slurry cannot be effectively removed, resulting in unsatisfactory purification effect of the slurry and affecting the quality of the coating process;

[0006] Demagnetization cart: Since the slurry flows fast inside the equipment and there is pulsating motion, it is difficult for the magnetic material to firmly adhere to the surface of the magnetic rod and it frequently detaches from the magnetic rod. As a result, the magnetic material in the slurry frequently desorbs, resulting in the failure to completely remove the magnetic impurities, and the magnetic content of the slurry fluctuates greatly, affecting the stability of the demagnetization effect;

[0007] Electromagnetic demagnetization: Although electromagnetic demagnetization technology has improved to a certain extent compared to traditional methods, its demagnetization effect is still limited, especially when dealing with high-viscosity or high-concentration slurries. The removal effect of magnetic impurities is not significant, resulting in limited ability to increase magnetic content. In addition, the investment in electromagnetic demagnetization equipment is large, and high maintenance costs are required during operation, including maintenance of electromagnetic demagnetization equipment and electricity consumption, which leads to an increase in overall operating costs.

[0008] Therefore, we propose a slurry demagnetizer with continuous cycle demagnetization function. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4The utility model provides a technical solution: a slurry demagnetizer with a continuous circulation demagnetization function, comprising a base 1 and self-locking universal wheels 2 fixedly installed on the lower surface of the base 1 and distributed in a linear array. By installing the self-locking universal wheels 2 in a linear array under the base 1 of the slurry demagnetizer, the mobility and flexibility of the equipment are enhanced, so that it can roll freely in multiple directions, and the stability of the equipment when it is stationary is ensured by the self-locking function, thereby avoiding unnecessary sliding; in addition, the linear distribution helps to evenly share the load, improve the load-bearing capacity and overall stability of the equipment, a feed pipe 3 connected to an on-site slurry buffer tank is placed above the placement table of the base 1, and a transport component is connected to the outlet flange of the feed pipe 3. Through the cooperation of the feed pipe 3 and the transport component, the slurry is transported from the on-site slurry buffer tank through the feed pipe 3 to the transport component, which is responsible for further transporting the slurry to a designated location. The flange connection makes the connection between the feed pipe 3 and the transport component more firm and sealed, thereby avoiding the problem of leakage or unstable connection. A continuous circulation demagnetization mechanism is arranged above the left side of the transport component on the base 1, and the continuous circulation demagnetization mechanism includes a The first demagnetization component, the second demagnetization component, the third demagnetization component and the first electric valve 4, through the cooperation of the first demagnetization component, the second demagnetization component and the third demagnetization component, the slurry transported by the transport component is demagnetized multiple times by utilizing the different magnetic field strengths of the three, so as to effectively remove the magnetic substances therein, and by opening the first electric valve 4, the slurry after multiple demagnetization is divided into two, one part of which flows back to the on-site slurry buffer tank to realize continuous circulation demagnetization of the slurry. In the above scheme, the first electric valve 4 is used to control the direction of the slurry flow to ensure that after multiple demagnetizations, , the slurry can flow back to the on-site storage tank again to complete the continuous cycle demagnetization process, thereby not only improving the demagnetization efficiency, but also ensuring the quality of the slurry, and avoiding the influence of magnetic impurities on subsequent processes. A mounting frame is fixedly installed on the upper surface of the base 1, and a controller 5 for controlling the operation of the transport component and the continuous cycle demagnetization mechanism is fixedly installed above the mounting frame. Since the controller 5 in this application is not improved when it is used, the movement process of controlling the transport component and the continuous cycle demagnetization mechanism is within the scope of the prior art and will not be elaborated here.

[0026] Further, the transport component includes a connecting pipe 6, the feed port of the connecting pipe 6 is flange-connected to the discharge port of the feed pipe 3, the discharge port of the connecting pipe 6 is flange-connected to a circulation pipe 62, a spring collar 61 is fixedly connected to the lower surface of the mounting frame, the inner wall of the spring collar 61 is clamped to the outer surface of the circulation pipe 62, in the above scheme, the feed port of the connecting pipe 6 is connected to the discharge port of the feed pipe 3 through the flange, which can ensure that the slurry flows smoothly from the feed pipe 3 into the connecting pipe 6, and is subsequently transported through the circulation pipe 62, in addition, the connecting pipe 6 and the circulation pipe 62 are detachably designed, which has the advantages of convenient disassembly and cleaning;

[0027] The outer surface of the circulation pipe 62 located on the left side of the mounting frame is fixedly connected with the second electric valve 63 and the first diaphragm pump 64 from right to left in sequence. The outer surface of the circulation pipe 62 located between the second electric valve 63 and the first diaphragm pump 64 is fixedly connected with a water supply pipe 65 connected to the external water source. The outer surface of the water supply pipe 65 is fixedly connected with a third electric valve 66. The first diaphragm pump 64 and the connecting pipe 6 are both in contact with the inner wall of the placement table at the corresponding position above the base 1. By setting the first diaphragm pump 64, the slurry in the on-site slurry buffer tank can be delivered to the feed pipe 3, and flow through the connecting pipe 6 and the circulation pipe 62 in sequence, and finally enter the continuous circulation demagnetization mechanism. In the demagnetization mechanism, the slurry will be demagnetized multiple times to ensure In order to ensure that impurities or magnetic substances are removed and the quality and performance of the slurry are optimized, the water supply pipe 65 and the third electric valve 66 are set to facilitate the subsequent regular cleaning of the continuous circulation demagnetization mechanism to ensure the stability and continuity of the demagnetization effect. During the demagnetization process, as time goes by, magnetic impurities and other substances will accumulate inside the demagnetization mechanism, affecting the demagnetization efficiency. Therefore, through the design of the water supply pipe 65 and the third electric valve 66, clean water or cleaning fluid can be injected into the demagnetization mechanism when necessary for effective flushing and cleaning, which helps to remove accumulated impurities, thereby ensuring that the demagnetization mechanism always maintains an efficient working state and further improves the working performance and demagnetization effect of the slurry demagnetizer.

[0028] Furthermore, the continuous circulation demagnetization mechanism also includes a protective cover 41 fixedly mounted on the upper surface of the base 1. The primary demagnetization component, the secondary demagnetization component, and the tertiary demagnetization component are all located inside the protective cover 41 to prevent interference or damage to them by the external environment. The primary demagnetization component includes a primary demagnetization cylinder 42. A first electromagnet 421 is fixedly mounted on the inner wall of the left mounting hole of the primary demagnetization cylinder 42. The right side surface of the shell of the first electromagnet 421 is plugged into the inner wall of the positioning hole of the primary demagnetization cylinder 42, so that a stable connection is formed between the first electromagnet 421 and the primary demagnetization cylinder 42, ensuring that the first electromagnet 421 can stably and effectively generate a magnetic field when working, and demagnetize the slurry from the inside of the primary demagnetization cylinder 42. The magnetic impurities are initially demagnetized. The inner bottom wall of the primary demagnetization cylinder 42 is gradually tilted downward from right to left. The inner bottom wall of the primary demagnetization cylinder 42 is designed to be gradually tilted downward from right to left, which helps the slurry to form a certain flow rate and tilt angle when flowing through the primary demagnetization cylinder 42, which is beneficial to improving the demagnetization efficiency. The discharge port of the circulation pipe 62 is fixedly connected to the right side surface of the primary demagnetization cylinder 42, ensuring that the slurry can smoothly enter the demagnetization area after being transported to the primary demagnetization cylinder 42 through the circulation pipe 62. Through such a design, the slurry can fully contact the magnetic field generated by the electromagnet when entering the demagnetization cylinder, thereby ensuring that the primary demagnetization cylinder 42 can initially remove the more significant magnetic substances therein.

[0029] The secondary demagnetization component includes a secondary demagnetization cylinder 43, and a second electromagnet 431 is fixedly installed on the inner wall of the left mounting hole of the secondary demagnetization cylinder 43. The right side surface of the shell of the second electromagnet 431 is plugged into the inner wall of the positioning hole of the secondary demagnetization cylinder 43. Through the cooperation of the secondary demagnetization cylinder 43 and the second electromagnet 431, the second electromagnet 431 is firmly connected. After the second electromagnet 431 is energized, the magnetic field generated further enhances the removal effect of magnetic substances, especially in the secondary demagnetization cylinder 43. The top outer surface of the secondary demagnetization cylinder 43 is fixedly connected to the bottom outer surface of the primary demagnetization cylinder 42 through the first supporting block 432. The first supporting block 432 is located on the upper surface of the bottom outer surface of the primary demagnetization cylinder 42 and is embedded with a third electromagnet 422. In the present application, the first supporting block 432 not only plays a supporting role, but also removes the first demagnetization cylinder 42 from the primary demagnetization cylinder 42 through the embedded third electromagnet 422. The outside further enhances the demagnetization effect on the internal slurry. The inner bottom wall of the secondary demagnetization cylinder 43 is gradually tilted downward from left to right. The inner bottom wall of the secondary demagnetization cylinder 43 is designed to be gradually tilted downward from left to right, which helps the slurry to maintain a certain flow rate and direction when flowing through the secondary demagnetization cylinder 43, so as to further promote the removal of magnetic substances. The magnetic field strengths generated by the first electromagnet 421 and the third electromagnet 422 after being energized are the same, ensuring that the magnetic field distribution inside the primary demagnetization cylinder 42 is consistent, thereby achieving a more uniform and efficient demagnetization effect. A first flow port 433 is provided on the left side of the inner bottom wall of the primary demagnetization cylinder 42. The inner bottom wall of the first flow port 433 passes through the first support block 432 and is connected to the inner top wall of the secondary demagnetization cylinder 43, ensuring that the slurry can smoothly flow through the primary demagnetization cylinder 42 and enter the secondary demagnetization cylinder 43, thereby ensuring that the secondary demagnetization cylinder 43 can further remove magnetic substances.

[0030] The three-stage demagnetization assembly includes a three-stage demagnetization cylinder 44, the bottom outer surface of the three-stage demagnetization cylinder 44 is fixedly connected to the upper surface of the base 1, the inner wall of the left mounting hole of the three-stage demagnetization cylinder 44 is fixedly installed with a fourth electromagnet 441, the right side surface of the shell of the fourth electromagnet 441 is plugged into the inner wall of the positioning hole of the secondary demagnetization cylinder 43, the top outer surface of the three-stage demagnetization cylinder 44 is fixedly connected to the bottom outer surface of the secondary demagnetization cylinder 43 through the second support block 442, the second support block 442 is located on the upper surface of the bottom outer surface of the secondary demagnetization cylinder 43, and the fifth electromagnet 434 is embedded and installed, the front and rear inner walls of the first support block 432 and the second support block 442 They are all fixedly connected to the front and rear inner walls of the protective cover 41. The inner bottom wall of the tertiary demagnetization cylinder 44 is gradually inclined from right to left, which is helpful for controlling the flow rate and direction of the slurry flow, avoiding the stagnation phenomenon of the slurry when flowing through this part, and improving the removal effect of magnetic substances. The second electromagnet 431 and the fifth electromagnet 434 have the same magnetic field strength after being energized, ensuring that the magnetic field strength inside the secondary demagnetization cylinder 43 is evenly distributed, optimizing the demagnetization effect, and a second flow port 443 is opened on the right side of the inner bottom wall of the secondary demagnetization cylinder 43. The inner bottom wall of the second flow port 443 passes through the second support block 442 and is connected to the inner top wall of the tertiary demagnetization cylinder 44.

[0031] The sixth electromagnet 444 is embedded and installed on the upper surface of the base 1 located at the outer surface of the bottom end of the three-stage demagnetization cylinder 44. The slurry enters the three-stage demagnetization cylinder 44 through the second flow port 443. Under the action of the magnetic field of the fourth and sixth electromagnets 444, the remaining magnetic substances are finally removed. The magnetic field strengths generated by the fourth electromagnet 441 and the sixth electromagnet 444 after being energized are the same, and the magnetic field strengths generated by the first electromagnet 421, the second electromagnet 431 and the fourth electromagnet 441 after being energized gradually decrease. When the first electromagnet 421, the second electromagnet 431 and the fourth electromagnet 441 are energized in sequence, the effect of gradually decreasing the magnetic field strength is to gradually remove the magnetic substances through different stages. Process, initially, a stronger magnetic field can effectively adsorb and remove larger particles with stronger magnetism. As the magnetic field strength gradually weakens, the slurry demagnetizer can more accurately remove tiny particles with weaker magnetism. Through this design of gradually weakening the magnetic field strength, it is possible to avoid excessive adsorption of fine particles by a strong magnetic field, while improving the overall removal efficiency, so that magnetic materials at each stage can be efficiently and finely processed. In addition, the magnetic field strength generated by the first electromagnet 421, the second electromagnet 431, and the fourth electromagnet 441 after being energized can be achieved through an external adjustable power supply and the controller in this application. Since the specific operation process belongs to the scope of the prior art, it will not be described in detail here.

[0032] A discharge pipe 445 is fixedly connected to the left side of the inner bottom wall of the three-stage demagnetizing cylinder 44, and the discharge port of the discharge pipe 445 extends to the left side surface of the base 1 after passing through the base 1; the outer surface of the discharge pipe 445 located on the left side of the base 1 is fixedly connected to the second diaphragm pump 446, and the discharge port of the discharge pipe 445 is fixedly connected to a circulation pipe 447; the first electric valve 4 is fixedly installed on the end of the circulation pipe 447 near the front of the second diaphragm pump 446, and the other end of the circulation pipe 447 near the rear of the second diaphragm pump 446 is fixedly connected to the fourth electric valve 448; one end of the circulation pipe 447 near the first electric valve 4 is connected to the on-site slurry buffer tank, and the other end of the circulation pipe 447 near the fourth electric valve 448 is connected to the pre-coating buffer tank; the outer surface of the circulation pipe 447 located just in front of the discharge port of the discharge pipe 445 is fixedly connected to a water outlet pipe 4410, and the outer surface of the water outlet pipe 4410 is fixedly connected to a fifth electric valve 449.

[0033] Working principle: Step 1, the controller 5 controls the first diaphragm pump 64 and the second electric valve 63 to start, the first diaphragm pump 64 delivers the slurry in the on-site slurry buffer tank to the feed pipe 3, and flows through the connecting pipe 6 and the flow pipe 62 in sequence, and finally enters the continuous circulation demagnetization mechanism for multi-stage demagnetization;

[0034] Step 2: The specific demagnetization process of the continuous circulation demagnetization mechanism is as follows: after the slurry is transported to the primary demagnetization cylinder 42 through the circulation pipe 62, the slurry is subjected to the magnetic field generated by the primary electromagnet 421 and the third electromagnet 422, and the more significant magnetic substances therein are removed because the magnetic field strengths generated by the first electromagnet 421 and the third electromagnet 422 are the same after being energized;

[0035] Subsequently, the slurry enters the secondary demagnetization cylinder 43 through the first flow port 433 and continues to be affected by the magnetic field generated by the second electromagnet 431 and the fifth electromagnet 434 to further remove the remaining magnetic substances.

[0036] Finally, the slurry enters the area containing the fourth electromagnet 441 and the sixth electromagnet 444, and the magnetic field strength remains consistent to ensure the complete removal of the last tiny magnetic substances;

[0037] Step 3, the second diaphragm pump 446, the fourth electric valve 448 and the fifth electric valve 449 are started, and the slurry after multi-stage demagnetization treatment flows into the circulation pipe 447 through the discharge pipe 445. At this time, the flow of the slurry will be jointly controlled by the first electric valve 4 and the fourth electric valve 448. The slurry is divided into two parts, one part of which flows to one end of the first electric valve 4 and flows back to the on-site slurry buffer tank to achieve continuous circulation demagnetization of the slurry, and the other part flows to the other end of the fourth electric valve 448 and flows into the pre-coating buffer tank;

[0038] Step 4. When it is necessary to clean the continuous circulation demagnetization mechanism, the controller 5 controls the second electric valve 63, the first electric valve 4, the fourth electric valve 448, the first electromagnet 421, the second electromagnet 431, the third electromagnet 422, the fourth electromagnet 441, the fifth electromagnet 434 and the sixth electromagnet 444 to stop working, the fifth electric valve 449 is energized, and the first diaphragm pump 64 delivers clean water into the first demagnetization cylinder 42 through the water supply pipe 65 and the circulation pipe 62, and then uses the clean water to clean the first demagnetization cylinder 42, the second demagnetization cylinder 43 and the third demagnetization cylinder 44, and finally the clean water drives the magnetic impurities to be discharged through the outlet pipe 4410.
