Description

Technical Field

[0001] The utility model relates to the technical field of flame retardant production, in particular to an iron removal device for the production process of halogen-free cable flame retardants. Background Technique

[0002] Halogen-free cable flame retardants are widely used as flame retardant materials. When producing halogen-free cable flame retardants, it is necessary to remove metal impurities inside them.

[0003] The patent document with the publication number CN219898523U discloses an iron removal device for flame retardants, including a support frame and an iron removal cylinder; the right end of the iron removal cylinder is rotatably installed on the support frame through a support ring; the power mechanism includes a motor and a transmission assembly. The motor is installed on the left side wall of the support frame, and the driving end of the motor penetrates the left side wall of the support frame and extends into the iron removal cylinder and is connected with a rotating shaft. The above document still has deficiencies. When in use, the motor is started to drive the rotating shaft to rotate, thereby driving the stirring plate on the rotating shaft to rotate. When the stirring plate stirs the flame retardant, the iron impurities mixed in the flame retardant are adsorbed by the adsorption plate. At the same time, since the driving end of the motor is connected to the left end of the iron removal cylinder through the transmission assembly, the iron removal cylinder can be driven to rotate in the opposite direction relative to the rotation direction of the rotating shaft, so that the flame retardant can be in full contact with the adsorption plate, and the iron removal effect is better. However, when the above iron removal device removes metal iron impurities in halogen-free cable flame retardants, the metal iron impurities are adsorbed on the surface of the adsorption plate and need to be cleaned subsequently, and the operation is relatively troublesome. When removing iron during the production process of halogen-free cable flame retardants, it is not convenient to collect the metal impurities after iron removal. At the same time, when the halogen-free cable flame retardant is put into the inside of the box body, the falling speed is relatively fast, resulting in a poor iron removal effect when removing iron from the halogen-free cable flame retardant. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that it is not convenient to collect the metal impurities after iron removal, and to propose an iron removal device for the production process of halogen-free cable flame retardants.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design an iron removal device for the production process of halogen-free cable flame retardants, including a box body and a vertical plate. Two vertical plates are fixedly connected inside the box body. A scraping mechanism is arranged inside the vertical plates. Two connecting rods are fixedly connected inside the box body. Both of the two connecting rods are fixedly connected to the outer wall of the bracket. A slow-down mechanism is arranged inside the bracket. The box body is fixedly connected to the outer wall of the feeding hopper. A guide plate is fixedly connected inside the vertical plates.

[0007] Preferably, the scraping mechanism includes a sleeve fixedly connected to the outer wall of the vertical plate. A sliding rod is slidably connected inside the sleeve. A spring is arranged inside the sleeve, with both ends of the spring fixedly connected to the sleeve and the sliding rod respectively. The end of the sliding rod is fixedly connected to a scraper, and the scraper is rotatably connected to the box body through a pin shaft.

[0008] Preferably, the slowing mechanism includes a first motor fixedly connected to the lower surface of the bracket. The output shaft of the first motor is fixedly connected to a reciprocating lead screw, and the outer walls at both ends of the reciprocating lead screw are rotatably connected to the bracket through bearings. A lead screw nut is threadedly connected to the outer wall of the reciprocating lead screw, and the outer wall of the lead screw nut is slidably connected to the bracket. A cross bar is fixedly connected to the surface of the lead screw nut. Both ends of the cross bar are rotatably connected to a support rod through a pin shaft, and the end of the support rod is rotatably connected to an inclined plate through a pin shaft. Both ends of the two inclined plates are rotatably connected to the box body through a pin shaft.

[0009] Preferably, two magnetic rollers are rotatably connected to the inside of the box body through bearings, and the outer walls of the magnetic rollers are in contact with the scraper.

[0010] Preferably, the magnetic roller is fixedly connected to the output shaft of a second motor, and the second motor is fixedly connected to the surface of the box body.

[0011] Preferably, a first collection box and a second collection box are in clearance fit with the inside of the box body.

[0012] An iron removal device for the production process of halogen-free cable flame retardant proposed by the present utility model has the beneficial effects that: through the cooperation among the sleeve, the sliding rod, the spring and the scraper, the metallic iron impurities in the halogen-free cable flame retardant are adsorbed on the outer wall of the magnetic roller. The scraper is in contact with the outer wall of the magnetic roller. The scraper and the sliding rod move together, and the sliding rod slides inside the sleeve. The sliding rod and the sleeve play a guiding role in the rotation of the scraper. The spring can drive the sliding rod to slide under the elastic action, so that the scraper is more closely attached to the outer wall of the magnetic roller. The scraper cleans the metallic iron impurities adsorbed on the outer wall of the magnetic roller. The metallic iron impurities move along the inclined direction of the scraper and fall between the vertical plate and the box body into the inside of the first collection box. The operation is relatively simple. When removing iron during the production process of halogen-free cable flame retardant, it is convenient to collect the iron impurities after iron removal.

[0013] Through the cooperation among the first motor, the reciprocating lead screw, the lead screw nut, the cross bar, the support rod and the inclined plate, the first motor drives the reciprocating lead screw to rotate. The reciprocating lead screw drives the lead screw nut to slide up and down reciprocally. The lead screw nut drives the cross bar to move. The cross bar drives the two support rods to move. The support rods drive the inclined plate to move. The movement range of the lead screw nut is limited. When the inclined plate moves, it swings reciprocally. The inclined plate tosses up the non-halogen cable flame retardant, making the non-halogen cable flame retardant on its surface contact with the magnetic roller, slowing down the falling speed of the non-halogen cable flame retardant, increasing the contact between the non-halogen cable flame retardant and the magnetic roller, and making the iron removal effect of the non-halogen cable flame retardant better during iron removal.

[0023] A deceleration mechanism 4 is arranged inside the bracket 6. The deceleration mechanism 4 slows down the falling speed of the halogen-free cable flame retardant. The box body 1 is fixedly connected to the outer wall of the feeding hopper 7. A guiding plate 8 is fixedly connected inside the vertical plate 2. The guiding plate 8 guides the halogen-free cable flame retardant after iron removal, so that the halogen-free cable flame retardant falls into the second collection box 12. Two magnetic rollers 9 are rotatably connected inside the box body 1 through bearings. The magnetic roller 9 itself has strong magnetism. The outer wall of the magnetic roller 9 is in contact with the scraping plate 304. The scraping plate 304 cleans the outer wall of the magnetic roller 9.

The end of the sliding rod 302 is fixedly connected to the scraping plate 304. The sliding rod 302 and the scraping plate 304 move together. The scraping plate 304 is rotatably connected to the box body 1 through a pin shaft;

[0025] The metal iron impurities in the halogen-free cable flame retardant are adsorbed on the outer wall of the magnetic roller 9. The scraping plate 304 is in contact with the outer wall of the magnetic roller 9. The scraping plate 304 and the sliding rod 302 move together. The sliding rod 302 slides inside the sleeve 301. The sliding rod 302 and the sleeve 301 play a guiding role in the rotation of the scraping plate 304. The spring 303 can drive the sliding rod 302 to slide under the elastic action, so that the scraping plate 304 is more closely attached to the outer wall of the magnetic roller 9. The scraping plate 304 cleans the metal iron impurities adsorbed on the outer wall of the magnetic roller 9. The metal iron impurities move along the inclined direction of the scraping plate 304 and fall between the vertical plate 2 and the box body 1 into the first collection box 11. The operation is relatively simple. When removing iron during the production of the halogen-free cable flame retardant, it is convenient to collect the iron impurities after iron removal.

[0026] The deceleration mechanism 4 includes a first motor 401, a reciprocating lead screw 402, a lead screw nut 403, a cross bar 404, a support rod 405 and an inclined plate 406. The first motor 401 is fixedly connected to the lower surface of the bracket 6, and the output shaft of the first motor 401 is fixedly connected with the reciprocating lead screw 402. The first motor 401 drives the reciprocating lead screw 402 to rotate. The outer walls at both ends of the reciprocating lead screw 402 are rotationally connected to the bracket 6 through bearings. The outer wall of the reciprocating lead screw 402 is threadedly connected with the lead screw nut 403, and the reciprocating lead screw 402 drives the lead screw nut 403 to reciprocate;

[0027] The outer wall of the lead screw nut 403 is slidably connected to the bracket 6. The surface of the lead screw nut 403 is fixedly connected with the cross bar 404. The lead screw nut 403 drives the cross bar 404 to move. Both ends of the cross bar 404 are rotationally connected with support rods 405 through pins. The cross bar 404 drives the two support rods 405 to move. The end of the support rod 405 is rotationally connected with an inclined plate 406 through a pin. The support rod 405 drives the inclined plate 406 to move. Both ends of the two inclined plates 406 are rotationally connected to the box body 1 through pins. Barbs are arranged on the inclined plate 406 to further slow down the falling speed of the non-halogen cable flame retardant;

[0028] The first motor 401 drives the reciprocating lead screw 402 to rotate. The reciprocating lead screw 402 drives the lead screw nut 403 to reciprocate up and down. The lead screw nut 403 drives the cross bar 404 to move. The cross bar 404 drives the two support rods 405 to move. The support rod 405 drives the inclined plate 406 to move. The movement range of the lead screw nut 403 is limited. When the inclined plate 406 moves, it swings back and forth. The inclined plate 406 tosses up the non-halogen cable flame retardant, so that the non-halogen cable flame retardant on its surface contacts the magnetic roller 9, slows down the falling speed of the non-halogen cable flame retardant, and increases the contact between the non-halogen cable flame retardant and the magnetic roller 9, making the iron removal effect of the non-halogen cable flame retardant better during iron removal.

[0029] Working principle:

[0030] When using the iron removal device for the production process of non-halogen cable flame retardant to remove iron from the non-halogen cable flame retardant;

[0031] Metal iron impurity cleaning stage:

[0032] The second motor 10 drives the magnetic roller 9 to rotate. The magnetic roller 9 on the left rotates counterclockwise, and the magnetic roller 9 on the right rotates clockwise. The halogen-free cable flame retardant that needs to be iron-removed is put into the interior of the box body 1 through the feeding hopper 7. The halogen-free cable flame retardant contacts the magnetic roller 9, and the magnetic roller 9 adsorbs the metallic iron impurities in the halogen-free cable flame retardant. The metallic iron impurities in the halogen-free cable flame retardant are adsorbed on the outer wall of the magnetic roller 9. The scraper 304 fits against the outer wall of the magnetic roller 9. The scraper 304 moves together with the sliding rod 302. The sliding rod 302 slides inside the sleeve 301. The sliding rod 302 and the sleeve 301 play a guiding role in the rotation of the scraper 304. The spring 303 can drive the sliding rod 302 to slide under the elastic action, so that the scraper 304 fits more closely against the outer wall of the magnetic roller 9 (the spring 303 is in a stretched state in the attached drawing). The scraper 304 cleans the metallic iron impurities adsorbed on the outer wall of the magnetic roller 9. The metallic iron impurities move along the inclined direction of the scraper 304 and fall between the vertical plate 2 and the box body 1 into the interior of the first collection box 11. The operation is relatively simple, and it is convenient to collect the iron-removed metallic impurities during the production process of the halogen-free cable flame retardant;

[0033] Stage of slowing down the falling speed of the halogen-free cable flame retardant:

[0034] After the halogen-free cable flame retardant is added to the interior of the box body 1 through the feeding hopper 7, part of the halogen-free cable flame retardant directly contacts the magnetic roller 9, and part of the halogen-free cable flame retardant falls onto the inclined plate 406. The first motor 401 is started. The first motor 401 drives the reciprocating lead screw 402 to rotate. The reciprocating lead screw 402 drives the lead screw nut 403 to slide up and down reciprocally. The lead screw nut 403 drives the cross bar 404 to move. The cross bar 404 drives the two support rods 405 to move. The support rods 405 drive the inclined plate 406 to move. The movement range of the lead screw nut 403 is limited. The inclined plate 406 swings reciprocally during movement. The inclined plate 406 tosses up the halogen-free cable flame retardant, so that the halogen-free cable flame retardant on its surface contacts the magnetic roller 9, slows down the falling speed of the halogen-free cable flame retardant, increases the contact between the halogen-free cable flame retardant and the magnetic roller 9, and makes the iron-removing effect of the halogen-free cable flame retardant better during iron removal. The halogen-free cable flame retardant after iron removal falls into the interior of the second collection box 12.
