Technical Field

[0001] The utility model relates to the technical field of mica iron oxide processing, in particular to a circulating crushing device for processing mica iron oxide raw materials. Background Art

[0002] Mica iron oxide is a black and purple flaky crystalline powder. The widely used mica iron oxide is a fine powder screened from natural minerals. The coating made of mica iron oxide has good film formation, excellent adhesion and good connection characteristics, and can resist air pollution and ultraviolet radiation. After mining, the raw ore of mica iron oxide needs to be ground and crushed before subsequent processing. During the crushing process, due to different subsequent uses, the mica iron oxide also needs to be crushed into different specifications to meet the subsequent processing requirements;

[0003] However, most of the mica iron oxide raw material crushing devices in the prior art screen materials through a fixed screen plate. After long-term use, the screen plate has become clogged, making it difficult to form a good screening effect. At the same time, the mica iron oxide may be stacked, causing the device to fail to work as a whole. During the crushing process, some raw materials may not be completely crushed, resulting in some raw materials not meeting the requirements.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the mica iron oxide raw material crushing device in the prior art cannot ensure the normal operation of the screening material and the device as a whole, and cannot ensure that all the crushed raw materials meet the requirements, and to propose a circulating crushing device for processing mica iron oxide raw materials.

A discharge port is opened at the front end of the crushing box corresponding to the position of the screen plate, and a limiting plate is fixed at the front end of the crushing box corresponding to the position of the discharge port.

[0009] Furthermore, two crushing rollers are rotatably connected to the interior of the crushing box at a position corresponding to the position above the screen plate, and two crushing rollers rotatably connected to the interior of the crushing box are arranged above the crushing rollers. Guide plates are fixed on both sides of the interior of the crushing box corresponding to the crushing rollers and the positions above the crushing rollers, and two circulation outlets are symmetrically opened on both sides of the crushing box at the positions above the crushing rollers.

The sieve plate 19 is of a "∧"-shaped structure, and the sieve inside the sieve plate 19 is a detachable structure, which is convenient for replacement according to needs, and two vibration motors 15 are symmetrically fixed on both sides of the bottom of the sieve plate 19. A discharge port 8 is provided at the front end of the crushing box 1 corresponding to the position of the sieve plate 19, and a limiting plate is fixed at the front end of the crushing box 1 corresponding to the position of the discharge port 8. The bottom layer inside the crushing box 1 is in an inclined structure with the horizontal direction line, and the crushed raw materials are discharged through the discharge port 8. At the same time, the limiting plate forms a limiting effect to avoid being too scattered;

[0024] Two crushing rollers 17 are rotatably connected at the position above the screen plate 19 inside the crushing box 1, and two crushing rollers 9 are rotatably connected to the inside of the crushing box 1 above the crushing rollers 17. Guide plates 23 are fixed at the positions above the crushing rollers 9 and 17 on both sides of the crushing box 1, and two circulation outlets 18 are symmetrically opened at the positions above the crushing rollers 17 on both sides of the crushing box 1, and the front ends of the crushing rollers 17 and the crushing rollers 9 on one side penetrate and extend to the outside of the crushing box 1 to fix a first pulley 7, and the first belt 2 is rotatably connected between the two first pulleys 7, and the front end of one of the first pulleys 7 is connected to the second motor 6 fixed to the outside of the crushing box 1, and the rear ends of the crushing rollers 9 and the crushing rollers 17 penetrate and extend to the rear end of the crushing box 1 to fix a gear 22, and the two gears 22 on the same horizontal line are meshed with each other.

[0025] Pour the mica iron oxide raw material into the feed hopper 4, guide it to the top of the crushing roller 9 through the guide plate 23, start the second motor 6 to cooperate with the first belt 2 and the first pulley 7 to drive one of the crushing rollers 9 to rotate, the rotation of the crushing roller 9 drives the other crushing roller 9 to rotate through the meshing transmission of two gears 22, the two crushing rollers 9 rotate to crush the raw material into small pieces, and the crushed raw material falls above the two crushing rollers 17, and the second motor 6 is started and drives the two crushing rollers 17 to rotate to crush the crushed raw material;

[0026] The crushed raw materials fall onto the upper surface of the sieve plate 19, and the vibration motor 15 is started to cooperate with the fixed block 20 and the spring 21 to drive the sieve plate 19 to vibrate. The vibration of the sieve plate 19 drives the raw materials to move, and at the same time forms a screening effect on them. The raw materials that meet the specifications fall to the inner bottom layer of the crushing box 1 and are discharged through the discharge port 8. The raw materials that do not meet the specifications enter the circulation box 5 through the circulation inlet 11, thereby forming a circulation.

[0027] Embodiment 2:

[0028] This embodiment aims to solve the problem that during the pulverization of mica iron oxide raw materials in the prior art, part of the raw materials may not be completely pulverized, thereby causing part of the raw materials to fail to meet the requirements.

[0029] like Figure 5 As shown, the embodiment is a circulating crushing device for processing mica iron oxide raw materials, and two circulating boxes 5 are symmetrically fixed on both sides of the crushing box 1. An auger 10 is rotatably connected inside the circulating box 5. The size of the auger 10 is almost completely in line with the inner wall of the circulating box 5 to avoid the raw materials from falling. The bottom of the auger 10 passes through and extends to the inside of the crushing box 1, where a second pulley 12 is fixed. The two second pulleys 12 are rotatably connected by a second belt 13. The top of one of the augers 10 passes through and extends to the outside of the circulating box 5, where a first motor 3 is fixed. The first motor 3 is started to drive one of the augers 10 to rotate. The rotation of the auger 10 cooperates with the second pulley 12 and the second belt 13 to drive the other augers 10 to rotate, thereby driving the raw materials to rise. Two circulating inlets 11 are symmetrically opened on both sides of the inside of the crushing box 1 corresponding to the positions of the augers 10.

[0030] After the raw materials that do not meet the specifications enter the circulation box 5 through the circulation inlet 11, the first motor 3 is started to drive one of the augers 10 to rotate, and the rotation of the augers 10 cooperates with the second pulley 12 and the second belt 13 to drive the other augers 10 to rotate. The rotation of the two augers 10 drives the raw materials entering the circulation box 5 to rise until they reach the circulation outlet 18. The raw materials enter the crushing box 1 again through the circulation outlet 18, and then are crushed for the second time by the crushing roller 17. This cycle is repeated until it meets the requirements.

[0031] The working process and principle of the utility model are as follows:

[0032] Step 1: pour the mica iron oxide raw material into the feed hopper 4, guide it to the top of the crushing roller 9 through the guide plate 23, start the second motor 6 to cooperate with the first belt 2 and the first pulley 7 to drive one of the crushing rollers 9 to rotate, the rotation of the crushing roller 9 drives the other crushing roller 9 to rotate through the meshing transmission of two gears 22, the two crushing rollers 9 rotate to crush the raw material into small pieces, and the crushed raw material falls above the two crushing rollers 17, and the second motor 6 is started and drives the two crushing rollers 17 to rotate to crush the crushed raw material;

[0033] The crushed raw materials fall onto the upper surface of the sieve plate 19, and the vibration motor 15 is started to cooperate with the fixed block 20 and the spring 21 to drive the sieve plate 19 to vibrate. The vibration of the sieve plate 19 drives the raw materials to move, and at the same time forms a screening effect on them. The raw materials that meet the specifications fall to the inner bottom layer of the crushing box 1 and are discharged through the discharge port 8. The raw materials that do not meet the specifications enter the circulation box 5 through the circulation inlet 11, thereby forming a circulation;

[0034] Step 2: After the raw materials that do not meet the specifications enter the circulation box 5 through the circulation inlet 11, start the first motor 3 to drive one of the augers 10 to rotate, and the rotation of the augers 10 cooperates with the second pulley 12 and the second belt 13 to drive the other augers 10 to rotate. The rotation of the two augers 10 drives the raw materials entering the circulation box 5 to rise until they reach the circulation outlet 18. The raw materials enter the crushing box 1 again through the circulation outlet 18, and then are crushed for the second time by the crushing roller 17. This cycle is repeated until it meets the requirements.
