Description

Technical Field

[0001] This utility model relates to the technical field of sugarcane sugar processing equipment, and in particular to an extra-large, high-oil circulating, mobile, iron-discharging electromagnetic iron removal device for sugarcane layers. Background Technology

[0002] In the sugarcane sugar production process, raw materials inevitably become contaminated with ferromagnetic impurities such as iron filings and screws due to equipment wear or accidental spillage during transportation and pressing. If these impurities are not effectively removed, they can cause severe wear and even damage to subsequent critical equipment such as presses and pipeline pumps, and also affect the purity and quality of the final sugar product. Therefore, equipping the production line with electromagnetic iron removal devices to purify the sugarcane sap is a crucial step in ensuring production safety and product quality.

[0003] As the sugar industry continues to expand, the demand for processing efficiency is increasing, driving the development of electromagnetic iron removal devices towards "extra-large" sizes and high magnetic field strength. However, existing technologies, by simply increasing the size of the equipment and improving the power of the electromagnetic windings, have gradually revealed inherent defects in their structural design, which are significantly amplified during high-load continuous production.

[0004] On the one hand, the large-scale equipment processes sugarcane sap with enormous flow rates, and its adsorption of ferromagnetic impurities is extremely rapid, causing the iron-absorbing mechanism to reach saturation in a short time. Traditional cleaning methods typically require suspending the entire production line, then disconnecting the power to the iron-removing device and manually unloading and cleaning the iron. This periodic shutdown severely disrupts production continuity, creating a bottleneck that restricts overall production efficiency. This is especially problematic for large sugar mills that strive for uninterrupted operation, where the resulting time costs and capacity losses are unacceptable.

[0005] On the other hand, to generate a strong magnetic field sufficient to attract a large number of impurities, the electromagnetic windings of extra-large equipment need to carry a large current, which inevitably generates enormous Joule heat. If this heat cannot be dissipated effectively and in a timely manner, the winding temperature will continue to rise. Excessive temperature will not only accelerate the aging of the winding insulation layer and shorten the equipment's lifespan, but will also cause the magnetic field strength to weaken due to increased resistivity, directly affecting the iron removal effect and making it difficult for the equipment to maintain a stable and efficient working state for a long time. Existing cooling methods are often insufficient to meet the stringent heat dissipation requirements of extra-large equipment.

[0006] Therefore, this utility model proposes an extra-large, high-efficiency oil circulation mobile unloading electromagnetic iron removal device for sugarcane layers to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems existing in the technology of extra-large high-power oil circulation mobile unloading iron sugarcane layer electromagnetic iron removal device, the extra-large electromagnetic iron removal device needs to be shut down for manual cleaning after the adsorption of iron impurities is saturated, resulting in poor production continuity and low efficiency. In addition, the huge heat generated by the high-power electromagnetic winding is difficult to dissipate, affecting the stability of equipment operation and iron removal effect. The present invention aims to provide an extra-large high-power oil circulation mobile unloading iron sugarcane layer electromagnetic iron removal device with improved structure that can effectively solve the above problems.

[0008] This utility model provides an extra-large, high-pressure oil circulation mobile iron-removing device for sugarcane layers, comprising: a housing; an electromagnetic winding fixed inside the housing; an iron-attracting mechanism, the iron-attracting mechanism including an iron-attracting pipe passing through the electromagnetic winding, the bottom of the iron-attracting pipe having an iron-removing port; a high-pressure oil circulation mechanism; and an iron-removing mechanism.

[0009] The forced oil circulation mechanism includes a cold oil inlet and a hot oil circulation pipe connecting the inside of the housing, an oil pipe box located outside the housing, and a fan installed in the oil pipe box. The hot oil circulation pipe is circulated and connected to the oil pipe box to forcibly remove the heat from the electromagnetic winding and ensure stable operation of the equipment.

[0010] The unloading mechanism is located at the unloading port and includes a mounting plate, a motor, a gear, a fixing ring, a toothed ring, and a baffle. The motor is fixed to the mounting plate; the gear is fixed to the output end of the motor; the fixing ring is fixed to the mounting plate; the toothed ring is rotatably mounted on the mounting plate and meshes with the gear; the baffle is used to cover the unloading port.

[0011] The unloading mechanism also includes a linkage component, which includes a fixed post at the bottom of the fixed ring, a sliding groove on the gear ring, a limiting post on the gear ring, and an arc-shaped groove on the baffle. In the combined state, the fixed post slides inside the sliding groove, and the limiting post slides inside the arc-shaped groove. Through this precise mechanical linkage structure, the function of the motor driving the gear and gear ring to automatically open and close the baffle is realized, thus achieving automatic unloading of iron without stopping the machine.

[0012] Preferably, the magnet-absorbing mechanism also includes a feed pipe connected to the upper part of the magnet-absorbing pipe for injecting the sugarcane slurry to be treated into the equipment.

[0013] Preferably, the magnet mechanism also includes a valve installed on the feed pipe. The valve is used to precisely control the flow of sugarcane sap so that the feed of the pipe can be stopped independently when unloading iron from a single magnet pipe.

[0014] Preferably, the magnetic attraction mechanism also includes a discharge pipe connected to the bottom of the magnetic attraction tube, which is used to discharge the sugarcane sap after magnetic attraction and iron removal treatment.

[0015] Preferably, the device further includes an impurity removal mechanism, which includes a collection screen detachably connected to the outlet of the discharge pipe. The collection screen is used to perform secondary filtration on the discharged sugarcane juice to effectively remove non-magnetic impurities.

[0016] Preferably, the impurity removal mechanism also includes a quick-release component; the quick-release component includes a limiting block set on the discharge pipe and an L-groove opened at the opening of the collecting screen. The limiting block and the L-groove are engaged. This structure enables the quick installation and disassembly of the collecting screen, which greatly facilitates subsequent cleaning and maintenance.

[0017] Preferably, the number of baffles is five, and the five baffles are evenly distributed in a ring, which can achieve good sealing and smooth opening of the circular iron unloading port, ensuring the thoroughness of iron unloading.

[0018] Preferably, the baffle rotates around the axis of the fixed column. This structure clearly defines the movement trajectory and rotation center of the baffle, ensuring the accuracy and stability of the unloading mechanism during the linkage process.

[0019] This utility model has the following beneficial effects: 1. This utility model, by setting up an iron unloading mechanism, includes a motor, gear, gear ring, baffle, and linkage component. After the power is cut off to a single iron suction pipe, the motor can drive the gear to rotate the gear ring, and the gear ring can then drive the baffle to open the iron unloading port through the linkage component. This solves the problem in the prior art that after the electromagnetic iron removal device is saturated with impurities, the entire machine needs to be stopped for manual cleaning, resulting in low production efficiency and difficulty in continuous operation. It achieves the technical effect of automatically and mobilely unloading iron from a single iron suction pipe while the equipment is running, without stopping the machine, which greatly improves the continuity of production and the degree of automation.

[0020] 2. This utility model, by setting up a strong oil circulation mechanism, utilizes the circulation of cooling oil between the hot oil circulation pipe inside the shell and the oil pipe box outside, and cooperates with the fan to provide forced air cooling for the oil pipe box. This solves the problem of the huge heat generated by the long-term high-power operation of the extra-large electromagnetic winding, the difficulty of heat dissipation, the resulting unstable operation of the equipment, the weakening of the magnetic field, or even damage. It achieves the technical effect of efficiently removing the heat of the electromagnetic winding, keeping it within a safe temperature range, and ensuring that the equipment can continuously and stably generate a strong magnetic field for iron removal.

[0021] 3. This utility model solves the problem of filtering non-magnetic impurities in sugarcane juice after iron removal by setting an impurity removal mechanism and setting a collection screen at the end of the discharge pipe. The collection screen is detachably connected to the discharge pipe by using a quick-release assembly that cooperates with the limiting block and the L-groove. This also solves the problems of cumbersome cleaning and maintenance of the filter screen and inconvenient disassembly and assembly. It achieves secondary filtration of sugarcane juice, and the collection screen is easy to disassemble and assemble, easy to clean and maintain, thus improving the technical effect of the equipment's practicality.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example: Please refer to Figures 1 to 8 This utility model provides an extra-large, high-efficiency oil circulation mobile unloading electromagnetic iron removal device for sugarcane layers. It aims to solve the problems of low production efficiency caused by the need to stop cleaning after the extra-large electromagnetic iron removal device is saturated with iron impurities, and unstable operation caused by the difficulty in dissipating the high heat of the electromagnetic field.

[0026] The extra-large, high-power oil circulation mobile unloading electromagnetic iron removal device for sugarcane layers includes a housing 1 and an electromagnetic winding 2 fixed inside the housing 1; the housing 1 serves as the mounting base for the entire device, while the electromagnetic winding 2 is used to generate a strong magnetic field.

[0027] The magnet-attracting mechanism 3 is disposed in the housing 1. The magnet-attracting mechanism 3 includes a magnet-attracting tube 32 that passes through the electromagnetic winding 2. The bottom of the magnet-attracting tube 32 is provided with an iron discharge port 35. The magnet-attracting mechanism 3 also includes a feed pipe 31 that connects to the upper part of the magnet-attracting tube 32. A valve 33 is installed on the feed pipe 31. The magnet-attracting mechanism 3 also includes a discharge pipe 34 that connects to the bottom of the magnet-attracting tube 32.

[0028] The forced oil circulation mechanism 6 includes a cold oil inlet 61 and a hot oil circulation pipe 62 that connect the inside of the housing 1, an oil pipe box 63 located outside the housing 1, and a fan 64 installed in the oil pipe box 63. The hot oil circulation pipe 62 is in circulatory communication with the oil pipe box 63.

[0029] The unloading mechanism 4 includes a mounting plate 41, a motor 42, a gear 43, a baffle 44, a gear ring 45, a fixed ring 46, and a linkage assembly 47. The linkage assembly 47 includes a fixed post 471 located at the bottom of the fixed ring 46, a sliding groove 472 on the gear ring 45, a limiting post 473 on the gear ring 45, and an arc-shaped groove 474 on the baffle 44.

[0030] The impurity removal mechanism 5 includes a collection screen 51 and a quick-release assembly 52; the quick-release assembly 52 includes a limiting block 521 disposed on the discharge pipe 34 and an L-groove 522 opened at the opening of the collection screen 51.

[0031] The unloading mechanism 4 is located at the unloading port 35 at the bottom of the suction pipe 32; the unloading mechanism 4 has a mounting plate 41, which is fixed to the bottom of the suction pipe 32; the motor 42 is fixed on the mounting plate 41; the gear 43 is fixed to the output end of the motor 42; the fixing ring 46 is fixed on the mounting plate 41; the gear ring 45 is rotatably mounted on the mounting plate 41 and meshes with the gear 43; the gear ring 45 has a sliding groove 472 and a limit post 473; there are five baffles 44, which are used to cover the unloading port 35 and have an arc groove 474; the fixing post 471 of the linkage component 47 is located at the bottom of the fixing ring 46. In the assembled state, the fixed post 471 slides inside the sliding groove 472, and the limiting post 473 slides inside the arc-shaped groove 474. When the motor 42 drives the gear 43 to rotate, the gear 43 drives the gear ring 45 to rotate. The gear ring 45, through the sliding engagement of the limiting post 473 and the arc-shaped groove 474, drives the baffle 44 to rotate around the axis of the fixed post 471. At the same time, the fixed post 471 slides inside the sliding groove 472 for guidance. This engagement structure ensures that the baffle 44 can automatically unfold or close, realizing that after the electromagnetic winding 2 is de-energized, the adsorbed iron impurities are automatically discharged through the iron discharge port 35 under gravity, without the need to stop the machine.

[0032] The magnetic attraction mechanism 3 also includes a feed pipe 31 connected to the upper part of the magnetic attraction pipe 32, a valve 33 installed on the feed pipe 31, and a discharge pipe 34 connected to the bottom of the magnetic attraction pipe 32. The device also includes an impurity removal mechanism 5, which includes a collection screen 51 detachably connected to the outlet of the discharge pipe 34. The impurity removal mechanism 5 also includes a quick-release assembly 52, which includes a limiting block 521 set on the discharge pipe 34 and an L-groove 522 opened at the opening of the collection screen 51. The limiting block 521 and the L-groove 522 are engaged. The baffle 44 rotates around the axis of the fixed column 471, thereby opening or closing the unloading port 35.

[0033] The implementation principle of this application embodiment is as follows: the sugarcane layer electromagnetic iron removal device consists of an electromagnetic winding 2 and an iron-attracting mechanism 3 fixed inside the shell 1, and a collection screen 51 and a strong oil circulation mechanism 6 installed outside the shell 1. An iron-discharging mechanism 4 is opened at the bottom of the iron-attracting pipe 32, and the sugarcane juice after iron removal is discharged from the discharge pipe 34.

[0034] During the iron removal process of sugarcane sap, cooling oil is injected into the equipment through the cold oil inlet 61, the electromagnetic winding 2 is energized in advance, and then sugarcane sap is poured into the device through the feed pipe 31. As the sugarcane sap flows through the iron-absorbing pipe 32, iron impurities in the sugarcane layer are firmly attracted to the inner wall of the iron-absorbing pipe 32. After the iron removal process, the sugarcane sap is discharged from the discharge pipe 34 at the bottom of the iron-absorbing pipe 32. After a period of time, when the iron-absorbing pipe 32 reaches saturation, the iron-discharging mechanism 4 discharges the adsorbed iron impurities from the iron-absorbing pipe 32. The flow of sugarcane sap into each iron-absorbing pipe 32 is controlled by adjusting the valve 33 on the feed pipe 31. Closing one valve 33 stops the flow of sugarcane sap into one iron-absorbing pipe 32, and the sugarcane sap in the iron-absorbing pipe 32 is allowed to drain. The system is cleaned, and the external electromagnetic winding 2 of the magnetic pipe 32 is de-energized. The motor 42, which is fixed on the mounting plate 41 connected to the bottom of the iron discharge port 35, is started. The drive end of the motor 42 drives the gear 43 fixedly connected to it to rotate. The rotation of the gear 43 drives the gear ring 45 that meshes with it to rotate. At the same time, the fixing post 471 at the bottom of the fixing ring 46 slides and guides the gear ring 45 in the sliding groove 472 opened on the gear ring 45. The gear ring 45, which rotates around its own axis, slides in the arc groove 474 opened on the baffle 44 through the limiting post 473. The gear ring 45 drives the baffle 44 to rotate around the axis of the fixing post 471. With the cooperation of the linkage component 47, the five baffles 44 are unfolded. The iron impurities that lose magnetic attraction fall off under the influence of their own gravity and are finally collected through the iron discharge port 35 at the bottom of the magnetic pipe 32.

[0035] Non-magnetic impurities still exist in the sugarcane slurry after iron removal treatment. The impurity removal mechanism 5 is used to further treat the impurities in the sugarcane slurry. The opening of the collecting screen 51 is aligned with the discharge pipe 34. The limiting block 521 on the discharge pipe 34 is inserted into the outer slot of the L-groove 522 opened at the opening of the collecting screen 51. Then the collecting screen 51 is rotated so that the limiting block 521 is inserted into the L-groove 522. The non-magnetic impurities in the sugarcane slurry are blocked inside the collecting screen 51 by the filter. After stopping the machine, the collecting screen 51 is reversed and removed with the help of the quick-release assembly 52. ​​The non-magnetic impurities in the collecting screen 51 are removed and the collecting screen 51 is cleaned at the same time. The effect of quick disassembly and assembly of the filter screen and collection of impurities is achieved. Meanwhile, when the equipment is working, the cooling oil circulates between the hot oil circulation pipe 62 inside the housing 1 and the external oil pipe box 63. The cooling oil carries away the heat generated by the electromagnetic winding 2 and then dissipates the heat into the air through the fan 64, so that the electromagnetic winding 2 is always kept within a safe temperature range. The strong oil circulation mechanism 6 ensures that the magnet-attracting mechanism 3 continuously and stably attracts iron.
