Description

Technical Field

[0001] The utility model relates to the technical fields of chemical industry, plastics and food, in particular to an anti-blocking iron remover for powder material transportation. Background Art

[0002] In the prior art, the iron removal devices used in the powder material conveying pipeline all adopt a fixed magnetic frame with an ordinary multi-well-type upper and lower crossed circular magnetic bars (the magnetic field strength is generally 6000 Gauss). This type of magnetic frame has a low magnetic field strength, blocks the flow area, and has a poor iron removal effect. They are generally installed at the entrance of the downstream equipment, especially when conveying some high-viscosity, moist and ultra-fine powders that are easy to agglomerate, easy to agglomerate, and have poor fluidity. The magnetic frame of the fixed structure blocks the effective flow area at the material inlet, which reduces the flow area at the material inlet by more than 30%. Therefore, it often happens that the material adheres to the surface of the magnetic tube and accumulates thicker and thicker over time until the entire pipeline is blocked, resulting in a production stoppage accident. In order to resume production, workers have to climb into the air to dismantle the blocked pipeline and magnetic frame for cleaning. Not only does the cleaning work take a very long time and waste a lot of materials, but the work intensity and dust pollution are also extremely high. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2 In the embodiment of the utility model, a magnetic separator for preventing blocking of powder material is provided, comprising a magnetic separator housing 6, a reducer assembly 11, and a right end cover flange 13. The magnetic separator housing 6 is a four-way hollow tube structure with flanges on the upper, lower, left, and right sides. The magnetic separator housing 6 is made of a magnetically sparse material. The upper and lower flanges of the magnetic separator housing 6 are respectively used to connect the flanges of the inlet and outlet bins. The left and right end flanges of the magnetic separator housing 6 are respectively connected to the left end cover 3 and the right end cover 9. The right end cover 9 is provided with a right end small flange 14. The right end cover 9 and the right end cover flange 13 are connected by two conical arcs. The connecting block is integrated with the reducer assembly 11, the flange on the reducer assembly 11 is fixed to the right end cover flange 13, the other end of the reducer assembly 11 is connected to the motor 18, the shaft body 12 is installed in the shaft hole of the reducer assembly 11, the star-shaped bracket assembly 4 is installed on the left shaft of the shaft body 12, and the shaft end fixing cover 2 is installed on the left shaft end of the shaft body 12. The shaft body 12 transmits the rotational motion of the reducer assembly 11 to the star-shaped bracket assembly 4 through the first transmission flat key 7 and the second transmission flat key 16 installed thereon, and several strong magnetic bars 8 are installed between the two star-shaped bracket assemblies 4.

[0021] The star-shaped bracket assembly 4 is a five-pointed star-shaped three-piece or multi-piece welded structure. The star-shaped bracket assembly 4 is provided with a plurality of circular holes adapted to the strong magnetic rods 8 , and the circular holes are arranged in different layers at intervals of upper and lower layers and concentrically.

[0022] An oil filling cup 10 is provided on the outer cylindrical surface of the right end cover 9, and the oil filling cup 10 is used for filling grease.

[0023] An end cover handle 1 is installed on the left end cover 3, and the end cover handle 1 can facilitate the operator to open the left end cover 3. Four star hand wheels 5 are installed on the left end cover 3. The left end cover 3 is fixed to the left end flange of the iron remover housing 6 through the four star hand wheels 5. The left end cover 3 is used to take out the parts in the iron remover housing 6 and check or remove foreign matter.

[0024] See also Figure 3 A rotation detection sensor 17 is installed in the fixed mounting hole on the end face of the right end cover 9. A gap of 3-5 mm is left between the left end face of the rotation detection sensor 17 and the right end face of the star-shaped bracket assembly 4. The rotation detection sensor 17 is used to detect whether the movement state of the star-shaped bracket assembly 4 is rotating. The position of the mounting hole of the rotation detection sensor 17 must be set in the middle position of the five star-shaped gear pieces and the center circular surface. This can ensure that the rotation detection sensor 17 intermittently detects the rotation motion signal of the star-shaped bracket assembly 4, thereby ensuring the normal operation of the anti-bridging, anti-stuck and anti-blocking rotating strong magnetic iron remover device. Once the rotation detection sensor 17 fails to detect a signal, an alarm signal will be issued to prompt the staff to go to the site to check if there are large foreign objects or ferrous materials detected. At this time, the worker will loosen and remove the four star hand wheels 5 and the left end cover 3 to remove the foreign objects and check whether there are other foreign objects. If not, the end cover can be installed to continue production.

[0025] See also Figure 4 An anti-shear guide triangular cone 15 is provided at the left inner part of the upper flange cylindrical inlet of the iron remover housing 6. The anti-shear guide triangular cone 15 is used to prevent foreign matter and powder and particle materials from being stuck by the rotating star-shaped bracket assembly 4 and the strong magnetic rod 8 when entering.

[0026] The working principle of the utility model is:

[0027] During use, the material enters through the upper flange cylindrical entrance of the iron remover housing 6. At the same time, the motor 18 drives the shaft 12 to rotate through the reducer assembly 11. The shaft 12 drives the star-shaped bracket assembly 4 to rotate. The star-shaped bracket assembly 4 drives several strong magnetic bars 8 installed thereon. The strong magnetic bars 8 magnetically attract the iron materials in the material during the rotation of the star-shaped bracket assembly 4. Once the rotation detection sensor 17 detects no signal, it will send out an alarm signal to prompt the staff to go to the site to check if there are large foreign objects or ferrous materials detected. At this time, the worker will loosen and remove the four star-shaped hand wheels 5 and the left end cover 3 to remove the foreign objects and check whether there are other foreign objects. If not, the end cover can be installed to continue production.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
