[0025] 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 of 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.

[0026] Example 1

[0027] like Figure 1 , Figure 2As shown, the iron removal device in a dry feed equipment provided in this embodiment includes a front side plate 1 and a rear side plate 2 arranged oppositely, and another group of left side plates 3 and right side plates 4 arranged oppositely. The front side plate 1, the rear side plate 2, the left side plate 3, and the right side plate 4 are all L-shaped structures, and the edges of the two sides of the front side plate 1 and the rear side plate 2 are provided with connecting holes, and the edges of the two sides of the left side plate 3 and the right side plate 4 are respectively provided with connecting parts. The front side plate 1 and the rear side plate 2 are fixedly connected to each other through the connecting holes and the connecting parts of the left side plate 3 and the right side plate 4 to form a hollow cylinder 5 with an inlet 51 and an outlet 52. The front side plate 1 is provided with a first upper side plate 11 and a first lower side plate 12; the rear side plate 2 is provided with a second upper side plate 21 and a second lower side plate 22; the left side plate 3 is provided with a third upper side plate 31 and a third lower side plate 32; the right side plate 4 is provided with a fourth upper side plate 41 and a fourth lower side plate 42. A first magnetic device is provided on the first lower side plate 12 of the front side plate 1 and the second upper side plate 21 of the rear side plate 2. When the dry feed passes through the cylinder 5, the iron impurities therein are removed by the magnetic device.

[0028] In the prior art, the iron removal device is usually arranged vertically between the dry feed bin and the grinder, which can prevent iron debris from entering the grinder during the transmission of dry feed and causing equipment failure. After the dry feed enters the cylinder 5 from the inlet 51, the dry feed will slide along the cylinder wall to the outlet 52 by its own gravity, but in the process of feeding, it is still necessary to maintain a relatively stable and reasonable speed. If the drop is too fast, the iron removal effect will not meet the requirements, and in severe cases, it may even cause damage to the equipment. If the drop is too slow, the production efficiency will decrease.

[0029] In order to achieve the purpose of both meeting the requirements of iron removal and ensuring production efficiency, in the present embodiment, the front side plate 1, the rear side plate 2, the left side plate 3, and the right side plate 4 are all designed to be L-shaped bending structures, and the same angle θ is set between them, and the angle range of the angle θ is: 45°-120°. The preferred technical solution, the angle of the angle θ is 45°, 60°, 90°, 100° or 120°. In the present embodiment, the front side plate 1, the rear side plate 2, the left side plate 3, and the right side plate 4 are all designed to be L-shaped bending structures. The angle θ is 90°, wherein the front side plate 1 is bent into the first upper side plate 11 and the first lower side plate 12 at 90°, the rear side plate 2 is bent into the second upper side plate 21 and the second lower side plate 22 at 90°, the left side plate 3 is bent into the third upper side plate 31 and the third lower side plate 32 at 90°, and the right side plate 4 is bent into the fourth upper side plate 41 and the fourth lower side plate 42 at 90°. After repeated actual tests in production, it was found that when the L-shaped structure is bent into a 90° angle, the falling speed of the dry feed and the iron removal effect are most ideal.

[0030] In this embodiment, the front side plate 1, the rear side plate 2, the left side plate 3, and the right side plate 4 are made of stainless steel plates with a length of 7762 mm and a width of 330 mm. In order to connect and install more firmly, connection holes are set at the edges of both sides of the front side plate 1 and the rear side plate 2. They can be punched out by stamping or drilled by a drilling machine. The left side plate 3 and the right side plate 4 are fixedly connected by screws or rivets on the connection holes. Among them, the edges of both sides of the left side plate 3 are provided with fourth connection parts 34, and the edges of both sides of the right side plate 4 are provided with sixth connection parts 44. The fourth connection parts 34 and the sixth connection parts 44 are screwed together with the connection holes at the edges of both sides of the front side plate 1 and the rear side plate 2 to form a hollow cylinder 5.

[0033] The magnetic device provided in this embodiment can be arbitrarily matched with the front side plate 1, the rear side plate 2, the left side plate 3, and the right side plate 4 and snapped into the opening according to actual conditions. Compared with the traditional insertion-type iron removal method, it has a more flexible and convenient combination method, which can better ensure the production efficiency while ensuring the iron removal effect.
