Description

Technical Field

[0001] This utility model relates to the field of briquetting machine technology, specifically to a briquetting machine roller pre-pressing device. Background Technology

[0002] Briquetting machines are mainly used to press powdery materials that are difficult to form. They are characterized by high forming pressure, adjustable main machine speed, and a screw feeding device. They are mainly used for tailings treatment in minerals, such as coal powder forming; dry powder forming; desulfurized gypsum forming; coke powder forming; iron filings and various metal mineral powder forming, etc.

[0003] Existing briquetting machines have their feed hoppers located at the top, allowing powdered materials to be poured in directly during production. The powdered material remains loose upon entry, resulting in less than ideal briquetting performance for some powdered materials that are difficult to form. Therefore, an innovative design based on the existing briquetting machine is urgently needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-pressing device for the rollers of a briquetting machine, so as to solve the problem mentioned in the background art that the feed hopper of the existing briquetting machine is set at the top, and the powdered material is poured directly into it during production. The powdered material is still loose when it enters, and the briquetting effect is not ideal for some powdered materials that are difficult to form.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-pressing device for a briquetting machine, comprising a top frame, a hydraulic rod fixed to the side of the top frame, a top movable frame installed at the end of the hydraulic rod, a smooth pressure roller installed inside the top movable frame, a limiting plate fixed to the bottom of the outer side of the top frame, the inner side of the bottom of the limiting plate fitting against the top of the outer side of the bottom frame, a positioning bolt fixed to the top of the outer side of the bottom frame, a positioning nut installed at the end of the positioning bolt, the positioning bolt passing through a limiting window, the limiting window being located at the bottom end of the limiting plate, track windows opening on the front and rear sides of the bottom frame, a threaded rod passing through the track window, a locking nut installed at the end of the threaded rod, the middle part of the threaded rod being connected and fixed to the bottom movable frame, an upper pressure roller installed at the top of the inner side of the bottom movable frame, the upper pressure roller having a shallow vertical groove, a lower pressure roller installed at the bottom of the inner side of the bottom movable frame, the lower pressure roller having a shallow horizontal groove, and an mounting plate fixed to the bottom of the outer wall of the bottom frame.

[0006] Preferably, the hydraulic rods are symmetrically distributed about the center of the top movable frame, and the top movable frame and the smooth pressure roller are symmetrically distributed about the center of the top frame. The centers of the smooth pressure roller, the upper pressure roller and the lower pressure roller are on the same vertical plane.

[0007] Preferably, the limiting plates are symmetrically distributed about the center of the bottom frame, and the top view length of the limiting plates is greater than 3 / 4 of the top view length of the bottom frame.

[0008] Preferably, the inner wall of the limiting window is tightly fitted with the positioning bolts, and the positioning bolts are evenly distributed.

[0009] Preferably, the threaded rods are evenly spaced, the threaded rods are slidably connected to the track window, and the track window and locking nut are symmetrically arranged at both ends of the threaded rods.

[0010] Preferably, the upper pressure roller and the lower pressure roller are symmetrically distributed about the center of the bottom frame. Shallow vertical grooves are formed at equal intervals on the upper pressure roller, and shallow horizontal grooves are formed at equal angles about the center of the lower pressure roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the briquetting machine roller pre-compression device adopts a new structural design, and a pre-compression device is set at the top of the briquetting machine feed inlet, and the pre-compression device is equipped with multiple pairs of pre-compression rollers, which can pre-compress powdery materials with high molding difficulty, so that the powdery materials can enter the briquetting machine in a relatively compact state, thereby improving the briquetting effect;

[0012] 1. By using horizontally symmetrically distributed smooth pressure rollers, upper pressure rollers and lower pressure rollers, powdery materials that are difficult to form can be pre-pressed efficiently. This can compact the powdery materials in advance, allowing them to enter the briquetting machine in a relatively compact state, thereby improving the briquetting effect.

[0013] 2. The spacing of the symmetrically distributed smooth pressure rollers is adjusted by hydraulic rods, and the spacing of the symmetrically distributed upper and lower pressure rollers is adjusted by sliding the threaded rod along the track window to ensure the compaction effect on powdery materials. Furthermore, the structural design of the limiting plate, positioning bolts, positioning nuts, and limiting window allows for convenient adjustment of the spacing between the top and bottom frames. This facilitates adjusting the spacing between the smooth pressure rollers and the upper and lower pressure rollers according to the molding difficulty of the powdery materials, thereby improving the overall applicability and effectiveness of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a pre-pressing device for a briquetting machine roller, comprising a top frame 1, a hydraulic rod 2, a top movable frame 3, a smooth pressure roller 4, a limiting plate 5, a bottom frame 6, positioning bolts 7, positioning nuts 8, a limiting window 9, a track window 10, a threaded rod 11, a locking nut 12, a bottom movable frame 13, an upper pressure roller 14, a shallow vertical groove 15, a lower pressure roller 16, a shallow horizontal groove 17, and a mounting plate 18. The hydraulic rod 2 is fixed to the side of the top frame 1, and the top movable frame 3 is installed at the end of the hydraulic rod 2. The smooth pressure roller 4 is installed inside the top movable frame 3. The limiting plate 5 is fixed to the bottom of the outer side of the top frame 1, and the inner bottom side of the limiting plate 5 is in contact with the top of the outer side of the bottom frame 6. A positioning bolt 7 is fixed to the top of the outer side of the bottom frame 6. A positioning nut 8 is installed at the end of the positioning bolt 7. The positioning bolt 7 passes through the limiting window 9. The limiting window 9 is opened at the bottom of the limiting plate 5. Track windows 10 are opened on the front and rear sides of the bottom frame 6. A threaded rod 11 is installed through the track window 10. A locking nut 12 is installed at the end of the threaded rod 11. The middle part of the threaded rod 11 is connected and fixed to the bottom movable frame 13. An upper pressure roller 14 is installed on the top of the inner side of the bottom movable frame 13. A shallow vertical groove 15 is opened on the upper pressure roller 14. A lower pressure roller 16 is installed on the bottom of the inner side of the bottom movable frame 13. A shallow horizontal groove 17 is opened on the lower pressure roller 16. An installation plate 18 is fixed to the bottom of the outer side wall of the bottom frame 6.

[0022] In this example, the hydraulic rods 2 are symmetrically distributed about the center of the top movable frame 3. The top movable frame 3 and the smooth pressure roller 4 are both symmetrically distributed about the center of the top frame 1. The centers of the smooth pressure roller 4, the upper pressure roller 14, and the lower pressure roller 16 are on the same vertical plane. The above structural design allows the hydraulic rods 2 to easily control the working position of the smooth pressure roller 4. The smooth pressure roller 4 can cooperate with the upper pressure roller 14 and the lower pressure roller 16 to continuously compact powdery materials.

[0023] The limiting plate 5 is symmetrically distributed about the center of the bottom frame 6. The top view length of the limiting plate 5 is greater than 3 / 4 of the top view length of the bottom frame 6. The above structural design can stably position the top frame 1 and ensure the stable operation of the top frame 1.

[0024] The inner wall of the limiting window 9 is tightly fitted with the positioning bolts 7, which are evenly spaced. The above structural design allows the top frame 1 to slide relative to the limiting window 9 on the limiting plate 5 and the positioning bolts 7, making it easy to adjust the working height of the top frame 1.

[0025] The threaded rods 11 are evenly spaced and are slidably connected to the track window 10. The track window 10 and locking nut 12 are symmetrically arranged at both ends of the threaded rods 11. The above structural design allows the threaded rods 11 to slide horizontally along the track window 10 with the bottom movable frame 13, the upper pressure roller 14 and the lower pressure roller 16, and adjust the distance between the upper pressure roller 14 and the lower pressure roller 16.

[0026] The upper pressure roller 14 and the lower pressure roller 16 are symmetrically distributed about the center of the bottom frame 6. The upper pressure roller 14 has shallow vertical grooves 15 at equal intervals, and the lower pressure roller 16 has shallow horizontal grooves 17 at equal angles about the center of the lower pressure roller 16. The above structural design can work with the smooth pressure roller 4 to stably compact the powdery material.

[0027] Working principle: During installation, the base frame 6 is connected and fixed to the top of the feed hopper at the top of the briquetting machine via the mounting plate 18, and then... Figure 2 Loosen the positioning nut 8, push or pull the top frame 1, and the top frame 1 moves synchronously with the limiting plate 5. The limiting window 9 opened on the limiting plate 5 slides vertically along the positioning bolt 7 until the distance between the smooth pressure roller 4 and the upper pressure roller 14 is appropriate. Rotate the positioning nut 8 to press the limiting plate 5 and the bottom frame 6 to fit and fix it.

[0028] Next, control the hydraulic rod 2 to extend or shorten, adjust the spacing of the symmetrically distributed smooth pressure rollers 4, and push the threaded rod 11 to slide horizontally along the track window 10. Adjust the spacing of the symmetrically distributed upper pressure roller 14 and lower pressure roller 16, rotate the locking nut 12 inside the symmetrical mechanism to press the bottom frame 6 to fix it, and then start the drive mechanism of the smooth pressure roller 4, upper pressure roller 14 and lower pressure roller 16. Powdered material is poured in from the top of the top frame 1. The powdered material passes between the symmetrically distributed smooth pressure roller 4, upper pressure roller 14 and lower pressure roller 16 in sequence. After being compacted, it enters the feed hopper at the top of the briquetting machine for briquetting. This is the working principle of the roller pre-compression device of the briquetting machine.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
