Description

Technical Field

[0001] The invention relates to equipment for removing ferromagnetic impurities in a material flow, and in particular to a temperature-controlled ferromagnetic impurity separator assembly capable of automatically controlling and adjusting the working temperature. Background Art

[0002] As far as the known prior art is concerned, U.S. Patent No. 8,132,674 discloses a separation device (Continuous cleaning tramp metal separation device) that can continuously remove ferromagnetic impurities. The device uses a plurality of linear actuators to drive a series of magnetic bars (series of bars) to reciprocate in and out of a chamber provided with a wiper plate, so that the device can continuously remove ferromagnetic impurities. The main disadvantage of this device is that the continuous friction between the magnetic bars and the wiper plate will increase the working temperature of each magnetic bar, resulting in a decrease in the magnetism of each magnetic bar, or even a complete loss of magnetism.

[0003] In addition, China's utility model patent No. 204602393 discloses a fully automatic iron remover, which has a plurality of magnetic rod assemblies consisting of a magnetic rod and shafts located at both ends of the magnetic rod, each of which is fixed on a frame, and a sleeve is taken to be sleeved on the surface of the magnetic rod assembly, and the sleeve can be moved back and forth axially along the magnetic rod assembly to remove ferromagnetic impurities accumulated on the surface of the sleeve. This kind of iron remover, because the sleeve moves back and forth on the surface of the magnetic rod assembly, will also increase the working temperature of the magnetic rod assembly due to friction, resulting in a decrease in the magnetism of each magnetic rod assembly, or even a complete loss of magnetism. Summary of the invention

[0123] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0124] First, see Figure 1, as shown in FIG. 10, a preferred embodiment of the temperature-controlled ferromagnetic impurity separator assembly of the present invention is shown, and the temperature-controlled ferromagnetic impurity separator assembly 10 has a non-magnetic rod body 12 and a magnet group 14. The non-magnetic rod body 12 is made of non-magnetic materials such as stainless steel, titanium alloy, copper alloy or aluminum alloy. The non-magnetic rod body 12 has a hollow chamber 120, a first closed end 122, a second closed end 124 and a long axis XX'. The first closed end 122 has an air inlet 126, and the second closed end 124 has an exhaust port 128. The magnet group 14 includes a plurality of magnets 140 and a plurality of isolation sheets 142, each of which is arranged between two adjacent magnets 140. The magnet group 14 is arranged in the hollow chamber 120 in a manner of forming an air flow channel 16 along the long axis XX' of the non-magnetic rod body 12. In this embodiment, the air flow channel 16 is formed by the coaxial first through holes 160 of each magnet 140 and the second through holes 162 of each isolation sheet 142. Figure 1 As shown in the direction of the arrow, the external air flow can be introduced from the air inlet 126 by an air flow input member 18 connected to the first closed end 122, such as a duct quick connector, and discharged from the exhaust port 128 through the air flow channel 16. In this way, the temperature-controlled ferromagnetic impurity separator assembly 10 can utilize the external cooling air flow to reduce its ambient operating temperature during operation.

[0125] Next, see Figure 2 FIG. 20 shows another preferred embodiment of the temperature-controlled ferromagnetic impurity separator assembly of the present invention. The temperature-controlled ferromagnetic impurity separator assembly 20 comprises a non-magnetic rod 22, a magnet group 24, a non-magnetic sleeve 26 and a non-magnetic inner tube 28.

[0126] The non-magnetic rod body 22 has a hollow chamber 220, a first closed end 222, a second closed end 224 and a long axis Y-Y'. The first closed end 222 has an air inlet 226, and the second closed end 224 has an exhaust port 228. The hollow chamber 220 has a first portion 230 and a second portion 232. The magnet group 24 also includes a plurality of magnets 240 and a plurality of isolation sheets 242, each of which is arranged between two adjacent magnets 240. The magnet group 24 is accommodated in the second portion 232 of the hollow chamber 220 to form a magnetic area 202, and the first portion 230 of the hollow chamber 220 forms a non-magnetic area 204. Each of the magnets 240 is provided with a first through hole 270, and each of the isolation sheets 242 is provided with a second through hole 272. The non-magnetic sleeve 26 is sleeved on the outside of the non-magnetic rod 22 and can reciprocate between a first position and a second position along the long axis Y-Y' of the non-magnetic rod 22. The length d1 of the non-magnetic sleeve 26 is shorter than the length d2 of the non-magnetic rod 22. In this embodiment, d1 is half of d2. Thus, when the non-magnetic sleeve 26 is located at the first position, it corresponds to the magnetic area 202, and is used to make the surface of the non-magnetic sleeve 26 adsorb ferromagnetic impurities in the material flow. When the non-magnetic sleeve 26 is located at the second position, it corresponds to the non-magnetic area 204, and is used to make the ferromagnetic impurities adsorbed on the surface of the non-magnetic sleeve 26 separate. The non-magnetic inner tube 28 is arranged in the first part 230 of the hollow chamber 220 of the non-magnetic rod 22, and abuts against one end of the magnet group 24. On the one hand, it is used to fix the magnet group 24, and on the other hand, it can strengthen the strength of the non-magnetic rod 22. In addition, it must be mentioned that, in this embodiment, the temperature-controlled ferromagnetic impurity separator assembly 20 has an airflow channel 27, which is composed of the first through hole 270 of each magnet 240, the second through hole 272 of each isolation sheet 242, and the hollow core 280 of the non-magnetic inner tube 28. Thus, similarly, the external airflow can be introduced from the air inlet 226 by an airflow input member 29 connected to the first closed end 222, and discharged from the exhaust port 228 through the airflow channel 27, so that the temperature-controlled ferromagnetic impurity separator assembly 20 can be maintained at a certain working temperature.

[0127] Also, see Figures 3 to 11 Another preferred embodiment of the temperature-controlled ferromagnetic impurity separator assembly of the present invention is shown in Figure 30. Basically, the temperature-controlled ferromagnetic impurity separator assembly 30 includes a frame 40, a plurality of non-magnetic rods 60, a plurality of magnet groups 70, a plurality of non-magnetic sleeves 90, a control device 200, a gas delivery device 300, a temperature sensing device 400, and a pneumatic cylinder group 500.

[0128] The frame 40 has a first end wall 42, a second end wall 44, and a first side wall 46 and a second side wall 48 respectively between the end walls 42 and 44. The end walls 42 and 44 and the side walls 46 and 48 define a receiving space 50. The frame 40 also has a first and a second fixing plate 52 and 54, which divide the receiving space 50 into a central feeding area 56, a first cleaning area 57 and a second cleaning area 58. The central feeding area 56 is used for the inflow of materials. A material outlet 560 is provided at the bottom of the central feeding area 56 for the discharge of materials. The first cleaning area 57 and the second cleaning area 58 are used for collecting ferromagnetic impurities. The bottoms of the first and second cleaning areas 57 and 58 are provided with a first and a second impurity discharge outlet 570 and 580 respectively.

[0129] The non-magnetic rod 60, please refer to Figure 5 , made of non-magnetic materials such as stainless steel, titanium alloy, copper alloy or aluminum alloy, having a hollow chamber 62, a first closed end 63, a second closed end 64 and a long axis Z-Z'. The first closed end 63 has an air inlet 630, and the second closed end 64 has an exhaust port 640. The non-magnetic rod 60 is fixed to each of the end walls 42, 44 at both ends by appropriate fasteners, such as bolts (not shown in the figure). The hollow chamber 62 has a first portion 620, a second portion 622 and a third portion 624 in sequence. In this embodiment, the first portion 620 and the third portion 624 have the same length; a magnet group 70 is arranged on the second portion 622, so that the second portion 622 forms a magnetic area 702, and the first portion 620 and the third portion 624 form a first non-magnetic area 704 and a second non-magnetic area 706 respectively. The magnet assembly 70 includes a plurality of permanent magnets 72 and a plurality of spacers 74, each of which is disposed between two adjacent permanent magnets 72. In addition, each of the magnets 72 is provided with a first through hole 720 and each of the spacers 74 is provided with a second through hole 740.

[0130] A first non-magnetic inner tube 100 is disposed in the first portion 620 of the hollow chamber 62 of the non-magnetic rod body 60, and a second non-magnetic inner tube 102 is disposed in the third portion 624 of the hollow chamber 62 of the non-magnetic rod body 60. The first and second non-magnetic inner tubes 100, 102 are used to reinforce the strength of the non-magnetic rod body 60 and can also be used to abut against both sides of the magnet group 70, in other words, the magnet group 70 is fixed to the second portion 622 of the hollow chamber 62 of the non-magnetic rod body 60.

[0131] In addition, it must be mentioned that in this embodiment, the temperature-controlled ferromagnetic impurity separator assembly 30 has an airflow channel 32, which is composed of the hollow core 104 of the first non-magnetic inner tube 100, the first through holes 720 of each magnet 72, the second through holes 740 of each isolation sheet 74, and the hollow core 106 of the second non-magnetic inner tube 102. In this way, similarly, the external airflow can be introduced from the air inlet 630 by the gas delivery device 300, and discharged from the exhaust port 640 through the airflow channel 32, so that the temperature-controlled ferromagnetic impurity separator assembly 30 can be maintained at a certain working temperature.

[0132] Please refer to Figures 6 to 11 The non-magnetic sleeve 90 is made of a non-magnetic material and is sleeved on the outside of the non-magnetic rod body 60. In terms of fitting, after the non-magnetic sleeve 90 is sleeved on the surface of the non-magnetic rod body 60, it can reciprocate along the long axis Z-Z' of the non-magnetic rod body 60 between a first position and a second position. In this embodiment, the length of the non-magnetic sleeve 90 is approximately equal to the sum of the length of the magnetic area 702 of the non-magnetic rod body 60 and the length of one of the non-magnetic areas 704 (706). The non-magnetic sleeve 90 has a central convex ring 92 that divides the tube body into a first sleeve portion 902 and a second sleeve portion 904 of the same length. When the non-magnetic sleeve 90 is located at the first position, as Fig. 9 As shown, the first sleeve portion 902 corresponds to the magnetic region 702 of the non-magnetic rod 60, and the second sleeve portion 904 corresponds to the second non-magnetic region 706 of the non-magnetic rod 60. When the non-magnetic sleeve 90 is located at the second position, as shown in FIG. Fig.10 As shown, the second sleeve portion 904 corresponds to the magnetic area 702 of the non-magnetic rod body 60, and the first sleeve portion 902 corresponds to the first non-magnetic area 704 of the non-magnetic rod body 60. In addition, it must be mentioned that in this embodiment, the surface of the non-magnetic sleeve 90 is provided with a plurality of equally spaced flanges 94, which are used to divide the surface of the non-magnetic sleeve 90 into a plurality of receiving areas 96, and the width and outer diameter of each flange 94 are slightly smaller than the central convex ring 92, whereby the non-magnetic sleeve 90 can evenly absorb ferromagnetic impurities when it is at a position corresponding to the magnetic area 702 of the non-magnetic rod body 60, and the absorbed ferromagnetic impurities will not be scraped off by each of the fixing plates 52, 54 during reciprocating movement. In addition, a bushing 906, 908 is respectively mounted on both ends of the non-magnetic sleeve 90 to maintain the non-magnetic rod 60 at the axis of the non-magnetic sleeve 90 when the non-magnetic rod 60 is inserted therein, so as to ensure smooth relative movement between the two.

[0133] Please refer to Figure 3 , Figures 8 to 10The temperature-controlled ferromagnetic impurity separator assembly 30 has seven non-magnetic rods 60, which are divided into a first rod group and a second rod group. The first rod group has four non-magnetic rods 60 located in a first plane, parallel to each other and separated by a predetermined distance, and the second rod group has three non-magnetic rods 60 located in a second plane, parallel to each other and separated by a predetermined distance. The first plane is at a predetermined height from the second plane, and the first rod group and the second rod group are arranged alternately. Each of the non-magnetic rods 60 is fixed to the first and second end walls 42, 44 at its two side ends, and passes through each of the fixing plates 52, 54, so that the magnetic area 702 corresponds to the central feeding area 56, the first non-magnetic area 704 corresponds to the first cleaning area 57, and the second non-magnetic area 706 corresponds to the second cleaning area 58. Each of the non-magnetic sleeves 90 passes through each of the fixing plates 52, 54 and moves between the first position and the second position. When each of the non-magnetic sleeves 90 is located at the first position, Fig. 9 As shown, the first sleeve portion 902 corresponds to the central feeding area 56 and the magnetic area 702 of the non-magnetic rod 60, so the receiving areas 96 on its surface will evenly absorb the ferromagnetic impurities in the material flow flowing from the central feeding area 56, and the second sleeve portion 904 of the non-magnetic sleeve 90 corresponds to the second cleaning area 58 and the second non-magnetic area 706 of the non-magnetic rod 60. After a period of time, the non-magnetic sleeve 90 is moved to the second position. At this time, as shown in FIG. Fig.10 As shown, the first sleeve portion 902 of the non-magnetic sleeve 90 will correspond to the first cleaning area 57, and the second sleeve portion 904 will correspond to the central feeding area 56. Since the first sleeve portion 902 of the non-magnetic sleeve 90 corresponds to the first cleaning area 57 and the first non-magnetic area 704 of the non-magnetic rod 60, the ferromagnetic impurities adsorbed by each of the receiving areas 96 on the surface of the non-magnetic sleeve 90 will be separated from the surface and fall into the first cleaning area 57, and the second sleeve portion 904 corresponds to the central feeding area 56 and the magnetic area 702 of the non-magnetic rod 60, and each of the receiving areas 96 on the surface will evenly adsorb the ferromagnetic impurities in the material flow flowing in from the central feeding area 56. In this way, when each of the non-magnetic sleeves 90 reciprocates between the first and second positions, the ferromagnetic impurities in the material flow can be automatically and continuously adsorbed and removed.

The second driving member 82 is located in the second cleaning area 58 and is fixed to the other end of the non-magnetic sleeve 90 through the bushing 908. In addition, the magnetic impurity separator assembly 30 also includes a driving device, which is two pneumatic cylinders 500 in this embodiment. Each of the pneumatic cylinders 500 is respectively fixed to the first and second side walls 46, 48 of the frame 40, and the piston 502 of each of the pneumatic cylinders 500 is respectively connected to the first driving member 80, whereby each of the non-magnetic sleeves 90 can be driven by each of the two pneumatic cylinders 500 to reciprocate between the first position and the second position. In addition, the magnetic impurity separator assembly 30 further includes two guide rods 84, which are respectively fixed on the first and second side walls 46, 48 of the frame 40 in a manner parallel to each non-magnetic rod body 60, and penetrate the openings 802, 822 provided on one side of each driving member 80, 82. In addition, a plastic bushing 86 is respectively fixed at the overlap between the two to reduce friction. In this way, each driving member 80, 82 can be driven by each of the two pneumatic cylinders 500 to move back and forth along each of the guide rods 84 with each of the non-magnetic sleeves 90. The temperature-controlled ferromagnetic impurity separator assembly 30 controls the action of each of the pneumatic cylinders 500 through a control device 200 installed on the frame 40. The control device 200 can usually be a programmable logic controller (PLC) to control each of the two pneumatic cylinders 500 to produce intermittent action, but is not limited thereto. Generally speaking, the control device 200 includes control elements such as an input module, a timing module, an execution module, and a solenoid valve.

[0135] In addition, it should be mentioned that the temperature control function of the magnetic impurity separator assembly 30, as mentioned above, the temperature-controlled ferromagnetic impurity separator assembly 30 has an air flow channel 32, and the air flow channel 32 is composed of the hollow core 104 of the first non-magnetic inner tube 100, the first through hole 720 of each of the magnets 72, the second through hole 740 of each of the isolation plates 74 and the hollow core 106 of the second non-magnetic inner tube 102. Thereby, the external air flow can be introduced from the air inlet 630 through the gas delivery device 300, and discharged from the exhaust port 640 through the air flow channel 32, so as to maintain the temperature-controlled ferromagnetic impurity separator assembly 30 at a certain operating temperature. Further, if Figure 3 and Figure 4As shown, the gas delivery device 300 includes a gas input component 302, a gas output component 304, and an action control component 306; the gas input component 302 is connected to an external airflow introduction device (not shown) for introducing a cooling airflow, the gas output component 304 is connected to the air inlet 630 of each non-magnetic rod body 60 for allowing the cooling airflow to be discharged to the exhaust port 640 through the airflow channel 32, and the action control component 306 is used to control the cooling airflow introduction action of the gas delivery device. In this embodiment, the gas delivery device 300 can be a gas pressure diverter, the gas output component 304 can be a duct quick connector, and the action control component 306 can be a solenoid valve. The temperature sensing device 400 may be a temperature probe or other similar element, which is arranged on the frame 40 in a manner that can sense the working environment temperature of the temperature-controlled ferromagnetic impurity separator assembly 30. In this embodiment, the temperature sensing device 400 is arranged on a side wall 46 of the central feeding area 56 of the frame 40. The temperature sensing device 400 is effectively connected to the action control component 306 of the gas conveying device 300. When the working environment temperature is equal to or greater than a first set temperature, the temperature sensing device 400 will output a start signal to the action control component 306 of the gas conveying device 300 for introducing a cooling airflow from the outside. When the ambient temperature is lower than or equal to a second set temperature, the temperature sensing device 400 will output a stop action signal to the action control component 306 of the gas conveying device 300 for stopping the introduction of the cooling airflow. The values ​​of the first and second set temperatures vary depending on the material of each of the magnets 72. For example, when each of the magnets 72 is made of neodymium iron boron (NdFeB) magnets, the first set temperature can be set between 40 degrees Celsius and 110 degrees Celsius, and the second set temperature can be relatively set between 30 degrees Celsius and 100 degrees Celsius. For example, the first set temperature can be set at 40 degrees Celsius, and the second set temperature can be set at 30 degrees Celsius.
