Description

Technical Field

[0001] The utility model belongs to the technical field of iron removal for calcium carbonate production, and particularly relates to an iron removal device for food-grade calcium carbonate production. Background Technique

[0002] Calcium carbonate is an inorganic compound and the main component of limestone, marble, etc. Calcium carbonate is usually a white crystal, odorless, basically insoluble in water, and easily reacts with acids to release carbon dioxide.

[0003] Some existing calcium carbonates are in granular form. When removing iron from them, workers need to grind the granular calcium carbonate into powder in advance before they can remove iron from it. This results in that after the granular calcium carbonate is ground into powder, it still needs to be transported to the position of the iron removal device and put into the iron removal device to remove iron. This process is rather cumbersome, time-consuming and laborious. Moreover, when some calcium carbonate iron removal devices remove iron, the calcium carbonate is exposed, which will cause dust in the air to fall on the calcium carbonate, resulting in the iron-removed calcium carbonate still containing unnecessary impurities and affecting the quality of calcium carbonate. In view of this, we propose an iron removal device for food-grade calcium carbonate production. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an iron removal device for food-grade calcium carbonate production to solve the problems put forward in the above background technique.

[0005] In view of this, the utility model provides an iron removal device for food-grade calcium carbonate production, including:

[0006] A housing, on the top of which a feed hopper is fixedly installed. A sealing cover is plugged and installed on the top of the feed hopper. A grinding groove is opened in the housing. Two grinding rollers I are symmetrically and rotatably installed in the grinding groove. Two grinding rollers II are symmetrically and rotatably installed in the grinding groove and below the grinding rollers I.

[0007] A driving component, which is located on one side of the housing and is used to drive the two grinding rollers I and the two grinding rollers II to rotate.

[0008] A discharge chute, which is opened in the housing and at the bottom of the grinding groove. A plurality of electromagnets are fixedly installed in the discharge chute. A sliding groove is opened in the housing and at the bottom of the discharge chute. A collection box is slidably installed in the sliding groove. A storage box is slidably installed in the sliding groove and at the bottom of the collection box.

[0009] In this technical solution, during use, the staff pulls up the sealing cover and opens it, then puts calcium carbonate particles into the feed hopper, and then closes the sealing cover. At this time, the calcium carbonate particles in the feed hopper will enter the grinding tank. Subsequently, through the set driving component, the driving component drives the two first grinding rollers to rotate towards each other. At the same time, the two second grinding rollers will also rotate towards each other. Then, the two first grinding rollers will conduct primary grinding on the calcium carbonate particles. The calcium carbonate particles after being ground by the two first grinding rollers will fall between the two second grinding rollers for secondary grinding to ensure that the calcium carbonate particles can be ground into powder;

[0010] Subsequently, the powdered calcium carbonate will fall downward from the grinding tank along with the iron powder. At this time, several electromagnets are powered on and made to work. The powdered calcium carbonate will enter the discharge tank along with the iron powder. At this time, the powdered calcium carbonate and the iron powder will come into full contact with several electromagnets, so that the iron powder will be adsorbed on several electromagnets, and the powdered calcium carbonate will fall downward and enter the collection box. After all the powdered calcium carbonate has removed the iron powder and fallen into the collection box, the staff can pull out the collection box from the sliding groove. Subsequently, the several electromagnets are powered off. At this time, the iron powder on the electromagnets will no longer be adsorbed on the electromagnets, and the iron powder will fall downward and fall into the storage box for collection. After all the iron powder has been collected, the storage box can be pulled out from the sliding groove to process the iron powder.

[0011] In the above technical solution, further, the driving component includes:

[0012] Two first gears, both of the two first gears are rotatably installed on one side of the housing, and the two first gears are meshed. One end of each of the two first gears penetrates through one side of the housing and is coaxially connected to the corresponding first grinding roller. Two second gears are rotatably installed on one side of the housing, and the two second gears are meshed. One end of each of the two second gears penetrates through one side of the housing and is coaxially connected to the corresponding second grinding roller;

[0013] A first transmission wheel, the first transmission wheel is fixedly installed on one side of one of the first gears. A second transmission wheel is rotatably installed on one side of one of the second gears. The second transmission wheel is directly below the first transmission wheel. A belt is installed for transmission between the first transmission wheel and the second transmission wheel;

[0014] An L-shaped plate, the L-shaped plate is fixedly installed on one side of the housing, and a motor is fixedly installed on the L-shaped plate. The output end of the motor penetrates through the L-shaped plate and is coaxially connected to the other first gear.

[0015] In this technical solution, start the motor, so that the output shaft of the motor drives another first gear to rotate. Under the action of meshing, the other first gear will drive one of the first gears to rotate. At this time, the two first gears will drive the corresponding first grinding rollers to rotate towards each other. The two first grinding rollers rotating towards each other will initially grind the calcium carbonate particles. Subsequently, one of the first gears will drive the first transmission wheel to rotate. The first transmission wheel drives the belt to drive, and the belt will drive the second transmission wheel to rotate. The second transmission wheel then drives one of the second gears to rotate. Under the action of meshing, the rotation of one of the second gears will drive the other second gear to rotate. Subsequently, the two second gears will drive the corresponding second grinding rollers to rotate towards each other.

[0016] In the above technical solution, further, the axis of the first transmission wheel and the axis of one of the first gears are on the same horizontal line, and the axis of the second transmission wheel and the axis of one of the second gears are on the same horizontal line.

[0017] In this technical solution, ensure that one of the first gears can drive the first transmission wheel to rotate normally; ensure that one of the second gears can drive the second transmission wheel to rotate normally.

[0018] In the above technical solution, further, the output shaft of the motor is rotatably connected to the L-shaped plate.

[0019] In this technical solution, ensure that the motor can operate normally.

[0020] In the above technical solution, further, the positions of several of the electromagnets are staggered from each other

[0021] In this technical solution, ensure that the iron powder in the powdered calcium carbonate can be fully adsorbed, so that the iron powder is separated from the powdered calcium carbonate.

[0022] In the above technical solution, further, the feed hopper is communicated with the grinding groove.

[0023] In this technical solution, ensure that the calcium carbonate particles in the feed hopper can enter the grinding groove.

[0024] The beneficial effects of the present utility model are:

[0025] 1. For this iron removal device for food-grade calcium carbonate production, through the cooperation of the set grinding groove, two first grinding rollers, two second grinding rollers and the driving assembly, it is ensured that the granular calcium carbonate can be ground into powder, and iron removal can be directly carried out after grinding into powder, without the need for workers to grind the granular calcium carbonate into powder in advance, and the operation is more convenient, faster, time-saving and labor-saving.

[0026] 2.
