Description

Technical Field

[0001] The utility model relates to the technical field of mold fluxes, in particular to a mold flux crushing and separating mechanism with a vibration screening structure. Background Technique

[0002] Mold fluxes are mainly used in the continuous casting process. During operation, the mold fluxes can isolate air to prevent the oxidation of molten steel, and at the same time have a heat preservation effect. Moreover, during operation, the mold fluxes can also absorb and dissolve impurities;

[0003] In the processing of mold fluxes, it is necessary to crush and screen the mold fluxes. After the mold fluxes are crushed, it can make the mold fluxes easier, more efficient, and more convenient for recycling in the subsequent use process. When crushing and screening the mold fluxes, a mold flux crushing and separating mechanism is required;

[0004] For example, a mold flux feeding and screening machine with the publication number of CN204934547U includes a material tank, a bottom plate, a first support spring, a shock isolation spring device, an armature, and an electromagnet coil matching the armature. The upper end of the shock isolation spring device is installed on the bottom plate. Among them, it further includes a partition plate, a second support spring, a support rod, and a screening hopper. The bottom plate and the partition plate are connected by the second support spring. The electromagnet coil is fixed on the bottom plate, and the armature is fixed on the partition plate. The electromagnet coil and the armature are arranged oppositely. The partition plate and the material tank are connected by the first support spring. The material tank is inclined. The screening hopper is located directly above the material tank, and the screening hopper and the material tank are fixedly connected by a support rod. This solution can filter the mold fluxes while transporting them. Compared with traditional equipment, it combines the two devices into one and cleverly combines the vibration source of the feeder, and only one vibration source is required to complete the operations of screening and feeding;

[0005] During the working process, after the mold fluxes are crushed, they need to be collected. However, general crushers only have the function of crushing, and general screening machines only have the function of screening, and do not have a structure for screening after crushing. The working content of the device is single, which leads to the low overall working efficiency of the device and brings unnecessary trouble to the process of crushing and screening the mold fluxes.

[0006] In view of the above problems, there is an urgent need to innovate and design on the basis of the original mold flux crushing and separating mechanism. Content of the Utility Model

[0007] The purpose of the utility model is to provide a mold flux crushing and separating mechanism with a vibration screening structure to solve the problems of single working content of the device in the above background technique, which leads to the low overall working efficiency of the device and brings unnecessary trouble to the process of crushing and screening the mold fluxes.

[0008] To achieve the above object, the present utility model provides the following technical solutions: A mold powder crushing and separating mechanism with a vibration screening structure, including a working frame and a rotating shaft. A motor is bolted to the rear side of the working frame, and the output end of the motor is fixedly connected to a connecting shaft. A long pin is vibrationally connected to the rear side surface of the working frame, and gears are fixedly connected to the surface of the long pin and the surface of the connecting shaft respectively.

[0009] The rotating shaft is rotatably arranged inside the working frame, and crushing rollers are fixedly connected to the surface of the rotating shaft and the surface of the connecting shaft respectively. A drainage plate is fixedly connected to the inner wall of the working frame.

[0010] A mold powder crushing and separating mechanism with a vibration screening structure further includes:

[0011] A pulley, which is sleeved and connected to the surface of the long pin, and the other side of the pulley is sleeved and connected to the surface of the rotating shaft.

[0012] A connecting rod, the upper surface of which is fixedly connected to the surface of the working frame, and the lower surface of the connecting rod is fixedly connected to a bottom frame. A blanking frame is fixedly connected to the lower surface of the working frame.

[0013] A screen, which is slidably arranged inside the bottom frame, and a column is fixedly connected to the upper surface of the screen.

[0014] An auxiliary plate, which is fixedly connected to the surface of the blanking frame.

[0015] Preferably, the drainage plates are symmetrically distributed about the center of the working frame, and the drainage plates are inclined.

[0016] Preferably, cams are fixedly connected to the ends of the connecting shaft and the rotating shaft respectively, and the cams correspond to the columns one by one.

[0017] Preferably, a side connecting plate is fixedly connected to the surface of the column, and a connecting spring for expected elastic reset is fixedly connected to the lower surface of the side connecting plate. The other side of the connecting spring is fixedly connected to the upper surface of the auxiliary plate.

[0018] Preferably, both sides of the screen are inclined, and the left and right sides of the bottom frame are through structures.

[0019] Preferably, a long rod is fixedly connected to the surface of the column, and the upper surface of the long rod is in contact with the side surface of the blanking frame.

[0020] Preferably, all four sides of the blanking frame are inclined.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows: The mold powder crushing and separating mechanism with a vibration screening structure adopts a new structural design, and the specific content is as follows:

[0022] (1) When the mold powder crushing and separating mechanism with a vibration screening structure is working, raw materials enter the working frame through the diversion plate. After starting the motor, the motor drives the connecting shaft to rotate. When the connecting shaft rotates, it drives the long pin to rotate through the gear. When the long pin is working, it drives the rotating shaft to rotate through the pulley, and then the crushing rollers on both sides start to rotate, completing the most basic work of crushing the mold powder;

[0023] (2) After the mold powder is crushed by the mold powder crushing and separating mechanism with a vibration screening structure, it will enter the bottom frame through the feeding frame and fall on the screen. The opening on the lower side of the feeding frame is smaller than the opening on the upper side, so the feeding position of the mold powder is restricted, which is convenient for the screen to collect;

[0024] (3) When the mold powder crushing and separating mechanism with a vibration screening structure is working, the connecting shaft and the rotating shaft will drive their own cams to rotate. During the rotation of the cams, they will intermittently contact the columns. At this time, the columns will move in a reciprocating linear motion in the vertical direction under the action of the cams, connecting springs and auxiliary plates, and then the screen is in a vibrating state, accelerating the screening speed;

[0025] (4) Both sides of the screen of the mold powder crushing and separating mechanism with a vibration screening structure are inclined, which optimizes the process of discharging the mold powder from the screen. The two sides of the bottom frame can collect the mold powder, and the lower side of the bottom frame can collect the mold powder of another size;

[0026] (5) When the column moves in a reciprocating linear motion in the vertical direction, the column will drive the long rod to move synchronously. Then the long rod will hit the outer wall of the feeding frame again and again, making the feeding frame in a vibrating state, accelerating the falling process of the mold powder inside the feeding frame, and improving the working efficiency.

Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Please refer to Figures 1-6 , the present utility model provides the following technical solutions: A protective slag crushing and separating mechanism with a vibration screening structure:

[0036] Embodiment 1: By setting the crushing roller 8, the most basic crushing function is completed, as Figures 1-4 shown:

[0037] It includes a working frame 1 and a rotating shaft 6. A motor 2 is bolted to the rear side of the working frame 1, and the output end of the motor 2 is fixedly connected to a connecting shaft 3. Moreover, a long pin 4 is vibrationally connected to the rear side surface of the working frame 1, and gears 5 are fixedly connected to the surfaces of both the long pin 4 and the shown connecting shaft 3;

[0038] The rotating shaft 6 is rotatably arranged inside the working frame 1, and crushing rollers 8 are fixedly connected to the surfaces of both the rotating shaft 6 and the connecting shaft 3. Moreover, a drainage plate 9 is fixedly connected to the inner wall of the working frame 1;

[0039] A protective slag crushing and separating mechanism with a vibration screening structure further includes:

[0040] A pulley 7, the pulley 7 is sleeved and connected to the surface of the long pin 4, and the other side of the pulley 7 is sleeved and connected to the surface of the rotating shaft 6. A connecting rod 11, the upper surface of the connecting rod 11 is fixedly connected to the surface of the working frame 1, and the lower surface of the connecting rod 11 is fixedly connected to a bottom frame 13. Moreover, a blanking frame 12 is fixedly connected to the lower surface of the working frame 1;

[0041] The screen 14 is slidably arranged inside the bottom frame 13, and a vertical column 15 is fixedly connected to the upper surface of the screen 14. The auxiliary plate 17 is fixedly connected to the surface of the blanking frame 12. The diversion plates 9 are symmetrically distributed about the center of the working frame 1, and the diversion plates 9 are arranged in an inclined shape.

[0042] During operation, the raw materials enter the working frame 1 through the diversion plates 9. After starting the motor 2, the motor 2 drives the connecting shaft 3 to rotate. When the connecting shaft 3 rotates, it drives the long pin 4 to rotate through the gear 5. When the long pin 4 works, it drives the rotating shaft 6 to rotate through the pulley 7. Then, the crushing rollers 8 on both sides start to rotate, completing the basic work of crushing the protective slag. After the protective slag is crushed, it will enter the inside of the bottom frame 13 through the blanking frame 12 and fall on the screen 14. The opening on the lower side of the blanking frame 12 is smaller than the opening on the upper side. Thus, the blanking position of the protective slag is restricted, facilitating the collection and screening of the screen 14.

[0043] Embodiment 2: Different from Embodiment 1, through the arranged reciprocating mechanism, when the screen 14 works, it is in a vibrating state, facilitating rapid screening and blanking, as Figure 5 and Figure 6 shown:

[0044] The ends of the connecting shaft 3 and the rotating shaft 6 are both fixedly connected with cams 10, and the cams 10 correspond to the vertical columns 15 one by one.

[0045] The surface of the vertical column 15 is fixedly connected with a side connection plate 16, and a connecting spring 18 expecting an elastic reset effect is fixedly connected to the lower surface of the side connection plate 16. The other side of the connecting spring 18 is fixedly connected to the upper surface of the auxiliary plate 17. Both sides of the screen 14 are distributed in an inclined shape, and the left and right sides of the bottom frame 13 are through structures.

[0046] During operation, the connecting shaft 3 and the rotating shaft 6 will drive their own cams 10 to rotate. During the rotation of the cams 10, they will intermittently contact the vertical columns 15. When the cams 10 push the vertical columns 15, the vertical columns 15 drive the side connection plates 16 to descend. At this time, the connecting spring 18 is squeezed by the side connection plates 16 and the auxiliary plates 17. When the cams 10 continue to rotate until they do not contact the vertical columns 15, the vertical columns 15 rise under the action of the connecting spring 18. Repeating the above process, at this time, the vertical columns 15 make a reciprocating linear motion in the vertical direction. Then, the screen 14 is in a vibrating state, accelerating the screening speed, and both sides of the screen 14 are in an inclined shape, which also facilitates blanking.

[0047] Embodiment 3: Different from Embodiment 2, by arranging the long rod 19, the blanking of the blanking frame 12 can be accelerated, as Figure 1 and Figure 6 shown:

[0048] A long rod 19 is fixedly connected to the surface of the column 15, and the upper surface of the long rod 19 is in contact with the side surface of the blanking frame 12. The four sides of the blanking frame 12 are all inclined.

[0049] When the column 15 makes a reciprocating linear motion in the vertical direction, the column 15 will drive the long rod 19 to move synchronously. Furthermore, the long rod 19 will strike the outer wall of the blanking frame 12 time after time, making the blanking frame 12 in a vibrating state, accelerating the falling process of the protective slag inside the blanking frame 12, improving the working efficiency. At the same time, the long rod 19 also limits the rising height of the column 15, ensuring stability.

[0050] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
