Description

Technical Field

[0001] The utility model relates to the field of flame retardant production equipment, in particular to an automatic iron removal device for flame retardant production. Background Art

[0002] Flame retardant is a commonly used fireproof material with good fireproof performance and broad application prospects. In the production process, the raw materials of flame retardant are effectively processed through material selection, grinding, mixing, molding and other processes. During the material selection and mixing process, iron and other magnetic impurities in the raw materials need to be removed. The commonly used iron removal method is magnet adsorption. Although it can achieve good results, it is difficult to clean up the impurities due to the existence of magnetic force after the magnet adsorbs the impurities, which may affect the subsequent use.

[0003] In the prior art, there is also a method of effectively adsorbing iron chips by using electromagnets to adsorb magnets. For example, an electromagnetic adsorption roller is arranged above the conveyor belt, and the iron chips passing through the conveyor belt are automatically adsorbed on the adsorption roller. After a certain period of adsorption, the electromagnetic adsorption roller is powered off to release the magnetic adsorption effect, and the iron chips are automatically released and fall, thereby achieving separation of raw materials and iron chips.

[0004] However, this method has the following problems: (1) The adsorption roller is arranged above the conveyor belt. After the conveyor line has been running for a period of time, the iron filings will accumulate and thicken on the surface of the adsorption roller during the adsorption process. The conveying operation needs to be stopped to remove the iron filings on the adsorption roller, which affects production efficiency. (2) The adsorbed iron filings will still fall on the conveyor line when being cleaned. If the conveyor line is not effectively cleaned, the subsequent raw material transportation will still be mixed with this part of the iron filings after the conveyor line rotates, affecting the degree of cleaning. If the conveyor line is to be cleaned, it is also necessary to shut down the conveyor line, which affects production efficiency. Utility Model Content

[0005] The utility model aims to provide an automatic iron removal device for flame retardant production, so as to solve the problem that the electromagnetic iron removal method in the prior art needs to stop conveying and affects the production efficiency.

[0006] In order to solve the above problems, the automatic iron removal device for flame retardant production involved in the utility model adopts the following technical solutions:

[0007] An automatic iron removal device for flame retardant production comprises a conveying unit for conveying from front to back, the conveying unit comprises a first horizontal conveyor belt, a second horizontal conveyor belt lower than the first conveyor belt, and an inclined section connected between the first horizontal conveyor belt and the second horizontal conveyor belt, the inclined section gradually extends downward from front to back, and a notch is provided on the inclined section, an iron removal unit is arranged below the first horizontal conveyor belt, the iron removal unit comprises an electromagnetic adsorption plate group, the electromagnetic adsorption plate group comprises a mounting seat, an electromagnetic coil is provided on the mounting seat, a power supply and a control switch are connected to the electromagnetic coil, an iron plate is also fixed on the mounting seat, one side plate surface of the iron plate constitutes an adsorption surface, the electromagnetic adsorption plate group is movably arranged between the notch and the first horizontal conveyor belt, the iron plate has an adsorption position for moving toward the notch to bring the adsorption surface closer to the notch during the stroke following the activity of the electromagnetic adsorption plate group, and also has a release position for hanging the adsorption surface of the iron plate downward, the control switch controls the electromagnetic coil to be energized when the iron plate is in the adsorption position, and controls the electromagnetic coil to be de-energized when the iron plate is in the release position.

[0008] In a preferred embodiment, the iron removal unit also includes a main shaft, the axis of the main shaft extends in the left-right direction, one end of the main shaft is connected to a driving motor, a connecting rod is connected between the electromagnetic adsorption plate group and the main shaft, and the electromagnetic adsorption plate group realizes switching between the adsorption position and the release position during the swinging process around the axis of the main shaft.

[0009] In a preferred embodiment, there are more than two electromagnetic adsorption plate groups, which are arranged at intervals in the circumferential direction around the main axis.

[0010] In a preferred embodiment, the mounting seat includes a base plate and a support frame filled in the base plate, the electromagnetic coil is sleeved on the support frame, the base plate and the support frame are fixed as a whole by epoxy resin pouring, and the iron plate is surrounded and fixed to the base plate.

[0011] In a preferred embodiment, there are more than two electromagnetic coils, which are arranged side by side in the substrate, and the electromagnetic coils are connected in parallel.

[0012] In a preferred embodiment, a controller is also provided on the electromagnetic adsorption plate group, and the controller is controllably connected to the control switch.

[0013] In a preferred embodiment, there is a gap extending up and down between the tail end of the inclined section and the second horizontal conveying line, and the gap constitutes the gap.

[0014] As described above, the utility model has the following beneficial effects: compared with the prior art, the automatic iron removal device for flame retardant production involved in the utility model, in the actual working process, the raw material is poured from the first horizontal conveyor belt to the second horizontal conveyor belt, and passes through the notch position of the inclined section. At this time, the iron plate on the corresponding electromagnetic adsorption plate group is at the notch, and the control switch controls the electromagnetic coil to be energized. The iron plate has a magnetic adsorption force through the principle of electromagnetism. At this time, since the adsorption surface of the iron plate is near the notch, the iron filings in the raw material are adsorbed and adsorbed on the iron plate. After a certain period of adsorption, when the surface of the iron plate adsorbs more iron filings, the external mechanism controls the electromagnetic adsorption plate group to move to the release position, and the electromagnetic coil loses power, thereby releasing the iron filings and completing the separation and collection of the iron filings and raw materials. During the whole process, there is no need to stop the conveying. The conveying line is only designed as a split structure with inclined conveying, and the electromagnetic adsorption plate group is arranged at the notch of the inclined section. The structure is simple and easy to control. It can effectively avoid the re-accumulation of iron filings on the conveying line and avoid shutdowns for maintenance and cleaning operations, which can greatly improve the production efficiency of flame retardants.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] The specific embodiment of the automatic iron removal device for flame retardant production involved in the utility model is as follows: Figures 1 to 3 As shown, the automatic iron removal device for flame retardant production includes a conveying unit that conveys from front to back, and the conveying unit includes a first horizontal conveyor belt 1, a second horizontal conveyor belt 2 lower than the first conveyor belt, and an inclined section 3 connected between the first horizontal conveyor belt 1 and the second horizontal conveyor belt 2, the inclined section 3 gradually extends downward from front to back, and there is a notch 4 on the inclined section 3, wherein the raw material is conveyed to the inclined section 3 through the first horizontal conveyor belt 1, and freely falls to the second horizontal conveyor belt 2 after passing through the notch 4 of the inclined section 3, and further, in order to prevent the raw material from falling out from between the two conveyor belts, there is a gap extending up and down between the tail end of the inclined section 3 and the second horizontal conveyor line, and the gap constitutes the notch 4. In addition, the inclined section 3 itself is a curved inclined guide plate.

[0024] In addition, in order to realize the function of collecting iron filings in the raw material, an iron removal unit is arranged below the first horizontal conveyor belt 1, and the iron removal unit includes an electromagnetic adsorption plate group 5, which is movably arranged between the notch 4 and the first horizontal conveyor belt 1, that is, it switches back and forth between the notch 4 of the inclined section 3 and the first horizontal conveyor belt 1. Specifically, the iron removal unit also includes a main shaft 6, the axis of the main shaft 6 extends in the left and right directions, and one end of the main shaft 6 is connected to a driving motor 7. A connecting rod 9 is connected between the electromagnetic adsorption plate group 5 and the main shaft 6. The main shaft 6 rotates to drive the electromagnetic adsorption plate group 5 to swing around the main shaft 6. During the swinging process, the electromagnetic adsorption plate group 5 can rotate along the arc surface inclined guide plate of the inclined section 3, and its rotation center is consistent with the arc center of the inclined guide plate. In this way, the electromagnetic adsorption function can be realized when the electromagnetic adsorption plate group 5 is located at the top of the inclined section 3, and the corresponding iron filings can be adsorbed and separated from the raw material.

[0025] In order to realize the adsorption function of the electromagnetic adsorption plate group 5 on iron filings, the electromagnetic adsorption plate group 5 includes a mounting seat 8, on which an electromagnetic coil 11 is provided, and the electromagnetic coil 11 is connected to a power supply 12 and a control switch. An iron plate 10 is also fixed on the mounting seat 8, and one side surface of the iron plate 10 constitutes an adsorption surface. The iron plate 10 has an adsorption position in which it moves toward the notch 4 to move the adsorption surface toward the notch 4 during the movement of the electromagnetic adsorption plate group 5, and also has a release position in which the adsorption surface of the iron plate 10 is suspended downward. The control switch controls the electromagnetic coil 11 to be energized when the iron plate 10 is in the adsorption position, and controls the electromagnetic coil 11 to be de-energized when the iron plate 10 is in the release position.

[0026] Specifically in this embodiment, the electromagnetic adsorption plate group 5 realizes switching between the adsorption position and the release position during the swinging process around the axis of the main shaft 6.

[0027] Furthermore, in order to ensure the continuity of the adsorption effect, the above-mentioned electromagnetic adsorption plate groups 5 have more than two, which are arranged at intervals around the main shaft 6. In this embodiment, there are four electromagnetic adsorption plate groups 5, which are evenly spaced around the main shaft 6. At the same time, in order to ensure the continuity of adsorption, when the first electromagnetic adsorption plate group 5 is at the notch 4 (where the iron plate 10 of the electromagnetic adsorption plate group 5 is in an upright position), the previous electromagnetic adsorption plate group 5 is arranged below the upper end of the inclined section 3. At this time, the first electromagnetic adsorption plate group 5 is in a powered state, and the others are in a powered-off state. When it is necessary to release the iron filings on the first electromagnetic adsorption plate group 5, When the first electromagnetic adsorption plate group 5 moves downward, the main shaft 6 rotates, driving the first electromagnetic adsorption plate group 5 to swing downward. At the same time, the previous electromagnetic adsorption plate group 5 is energized and has a magnetic adsorption function. In the process of swinging downward from the top of the inclined section 3 to the notch 4, the magnetic adsorption force is always maintained. When the first electromagnetic adsorption plate group 5 moves downward, the adsorption surface on the iron plate 10 is on the lower side. At this time, the electromagnetic coil 11 of the electromagnetic adsorption plate group 5 loses power, and the iron filings are separated from the iron plate 10 downward due to their own weight. The four electromagnetic adsorption plate groups 5 repeat the above operation repeatedly, so as to achieve the automatic collection, separation and release of iron filings in the raw material without stopping the conveying.

[0028] Of course, in order to ensure stable installation of the electromagnetic coil 11 and the iron plate 10, the mounting seat 8 includes a substrate 14 and a support frame 15 filled in the substrate 14, the electromagnetic coil 11 is sleeved on the support frame 15, the substrate 14 and the support frame 15 are cast and fixed as a whole by an epoxy resin layer 16, and the iron plate 10 is surrounded and fixed with the substrate 14.

[0029] At the same time, in order to ensure the magnetic adsorption force of the iron plate 10, there are two electromagnetic coils 11, which are arranged side by side in the base plate 14, and each electromagnetic coil 11 is connected in parallel.

[0030] In order to facilitate independent control of each electromagnetic adsorption plate group 5, a controller 13 is further provided on the electromagnetic adsorption plate group 5, and the controller 13 is control-connected to the control switch.

[0031] At the same time, in order to collect iron chips, an iron chip collection trolley 17 is arranged directly below the iron removal unit.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
