Description

Technical Field

[0001] The invention relates to the field of ceramic processing, in particular to a single continuous ball grid plate filtering system and a grid grid unit installed in the single continuous ball grid plate filtering system. Background Art

[0002] As the use of the ore direct continuous ball system technology becomes more mature, the single continuous ball is promoted and applied. In comparison, the single continuous ball mainly adds a set of grid plate filtration system compared to the ordinary continuous ball. This filtration system is a grid grid installed on the grid plate, which is used to filter the slurry and discharge the slurry. However, as the use time goes by, the grid grid is easy to be blocked or damaged, and the grid grid blockage is easy to cause slurry discharge difficulties, resulting in swelling and leakage of slurry, and after the grid grid is damaged, small balls may leak out of the grid grid and come out of the slurry outlet with the mud, causing waste of balls in the single continuous ball and difficulty in slurry screening in the subsequent process; at the same time, the grid grid needs to be replaced if it is damaged. Since the existing grid grid is fixed to the grid plate connected to the inner side of the single connecting ball by bolts, if the grid grid needs to be replaced, the staff can only enter the single continuous ball from the inside to the outside to work. Before entering the ball, in order to avoid the high temperature of the participating mud to scald the staff, the mud in the ball needs to be released and cleaned before entering. As the use time increases, the bolts fixing the grille grid on the grille plate will also wear out, and residual mud or small stones may be stuck between the gaps between the two, making disassembly difficult. At the same time, this disassembly site is a confined space, and there are certain safety hazards in the operation. Ventilation equipment needs to be prepared in advance to keep the ball ventilated before operations can be carried out.

[0003] Therefore, the current mode of only being able to replace the grid mesh from the inside out in a single continuous ball is not only time-consuming, labor-intensive, and has potential safety hazards, but also seriously affects the continuity of production. Therefore, it is very necessary to solve the technical problem of only being able to replace the grid mesh of a single continuous ball from the inside out, improve the continuity of production, reduce maintenance costs, shorten maintenance time, and reduce the labor intensity of employees. Summary of the invention

[0004] The purpose of the present invention is to provide a single continuous ball grid plate filtering system that solves the problem that the existing single continuous ball grid mesh can only be replaced from the inside out, which is not only difficult to replace and labor-intensive, but also has potential safety hazards. Another purpose of the present invention is to provide a grid mesh unit that can directly disassemble and replace the grid mesh from the outside of the single continuous ball.

[0005] The technical solution of the present invention is: a monomer continuous ball grid plate filtration system, which is special in that it includes a monomer continuous ball mill, a grid plate installed in the monomer continuous ball mill, and a grid grid unit fixed on the grid plate. The mud generated after grinding in the monomer continuous ball mill is filtered by the grid grid and enters the slurry outlet of the monomer continuous ball mill through the liquid outlet hole penetrated on the slurry outlet pipe wall of the grid grid unit, and then leaves the monomer continuous ball mill.

[0006] Preferably, the grid plate is in the shape of a fan-shaped plate, and a plurality of grid plates are spliced ​​together to form a disc that fits the shape of the inner cavity of the monomer continuous ball mill.

[0007] Preferably, the grille plate is provided with a plurality of grille grid units.

[0008] Preferably, the grid unit comprises a slurry outlet pipe, a grid, a sealing plug, a locking block, a fixing sleeve and a locking nut;

[0009] The slurry outlet pipe is fixed on the grid plate;

[0010] The grid grid is fixed to one end of the grid grid tie rod and is built into the inner cavity of the slurry outlet pipe, and the grid grid is in contact with the end surface of the grid plate;

[0011] The sealing plug is densely filled in the inner cavity of the slurry outlet pipe, and a locking hole is penetrated in the center of the sealing plug;

[0012] The locking block is connected to the locking screw and then inserted into the locking hole. The locking block and the locking hole are interference fit. The end face of the locking block abuts against the other end of the grid grid tie rod to prevent the grid grid from axial displacement in the inner cavity of the slurry outlet pipe.

[0013] The slurry outlet pipe is provided with a plurality of liquid outlet holes on the pipe wall between the sealing plug and the grid grid;

[0014] The fixed sleeve is located at the other end of the slurry outlet pipe and its end is against the slurry outlet pipe. The locking screw passes through the bottom surface of the fixed sleeve and cooperates with the locking nut to connect the fixed sleeve with the sealing plug.

[0015] Another object of the present invention is to provide a grid grid unit for a single continuous ball grid plate filtering system, which is special in that it includes a slurry outlet pipe, a grid grid, a sealing plug, a locking block, a fixing sleeve, and a locking nut;

[0016] The grid grid is fixed to one end of the grid grid tie rod and is built into the inner cavity of the slurry outlet pipe, and the grid grid is in contact with the end surface of the grid plate;

[0017] The sealing plug is densely filled in the inner cavity of the slurry outlet pipe, and a locking hole is penetrated in the center of the sealing plug;

[0018] The locking block is connected to the locking screw and then inserted into the locking hole. The locking block and the locking hole are interference fit. The end face of the locking block abuts against the other end of the grid grid tie rod to prevent the grid grid from axial displacement in the inner cavity of the slurry outlet pipe.

[0019] The slurry outlet pipe is provided with a plurality of liquid outlet holes on the pipe wall between the sealing plug and the grid grid;

[0020] The fixed sleeve is located at the other end of the slurry outlet pipe and its end is against the slurry outlet pipe. The locking screw passes through the bottom surface of the fixed sleeve and cooperates with the locking nut to connect the fixed sleeve with the sealing plug.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The grid grid unit is fixed on the grid plate installed inside the monomer continuous ball grid plate filtration system. When the grid grid is blocked or damaged, only the left shell of the system needs to be removed to further directly replace the problematic grid grid unit outside the monomer continuous ball mill. There is no need to empty and clean the mud in the system, and the staff does not need to enter the monomer continuous ball for replacement, which eliminates the potential safety hazards when entering the monomer continuous ball mill for disassembly, reduces preparation time, and ensures production continuity;

[0023] At the same time, because the slurry outlet of the grille grid unit is located between the sealing plug and the grille grid, and the locking nut is set in the fixed sleeve, the mud is always out of contact with the locking nut, the locking nut will not be worn by the mud, and it is easy for employees to disassemble the locking nut, which improves work efficiency, reduces employees' labor intensity, and reduces maintenance costs.
