Description

Technical Field

[0001] This utility model relates to the technical field of refractory brick processing equipment, specifically to a device for repairing the splicing surface of refractory bricks from a waste liquid furnace. Background Technology

[0002] Refractory bricks are high-temperature resistant inorganic non-metallic materials primarily used as linings or structural components in high-temperature industrial environments (such as kilns and reactors). They ensure stable equipment operation by resisting high temperatures, molten material erosion, and thermal shock. The core characteristic of refractory bricks is their high-temperature resistance, while also possessing good thermal shock resistance, slag resistance, load softening temperature, and volume stability. Compared to ordinary building bricks, their composition, manufacturing process, and performance are more complex.

[0003] During kiln construction, the splicing surfaces of refractory bricks need to be ground and repaired to ensure the flatness of the kiln lining. However, the traditional repair method is manual, where the operator uses a hand-held grinding tool to grind the bricks. This method requires a lot of manpower and has low grinding efficiency. At the same time, the grinding process generates a lot of dust that fills the construction site, endangering the personal safety of the operators. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a device for repairing the splicing surface of refractory bricks in waste liquid furnaces.

[0005] The technical solution of this utility model is: a refractory brick splicing surface trimming device for waste liquid furnace, including a base and a positioning component and a grinding component set on the upper end face of the base; a U-shaped dust cover is set on the upper end face of the base, and an operation hole is provided through the outer side wall of the U-shaped dust cover. The positioning assembly includes a first positioning seat movably disposed on the upper surface of the base, a mounting sleeve slidably engaged with a U-shaped dust cover, a second positioning seat fitted on the mounting sleeve, and an operating rod movably hinged to the top of the mounting sleeve and abutting against the second positioning seat; a slider is connected to the bottom surface of the first positioning seat, and a guide rail is provided on the upper surface of the base that is slidably engaged with the slider; The grinding assembly includes two mounting supports that are slidably engaged with the upper surface of the base and located on both sides of the first positioning seat, grinding rods that are rotatably engaged with the two mounting supports, and drive motors that are respectively set on the two mounting supports and connected to the grinding rods at corresponding positions. The bottom end of each mounting support is provided with a threaded seat that is slidably engaged with the base. An adjusting screw that is rotatably engaged with the two threaded seats is simultaneously threadedly connected to the base. The internal threads on the two threaded seats have opposite directions of rotation.

[0006] Furthermore, the top of the second positioning seat is provided with a pressing rod that penetrates the mounting sleeve, and a return spring that abuts against the inner wall of the mounting sleeve is sleeved on the pressing rod; the operating rod is movably hinged to the mounting sleeve through the support plate, and an arc-shaped pressing block that abuts against the pressing rod is provided on the bottom surface of the operating rod; Instructions: When in use, press the operating lever so that the arc-shaped extrusion block pushes the extrusion rod downward along the mounting sleeve. At this time, the second positioning seat approaches the first positioning seat to clamp and fix the refractory brick, improving the stability of the refractory brick during grinding and finishing.

[0007] Furthermore, clamping seats are slidably engaged on both sides of the upper end face of the first positioning seat via sliding rods, and compression springs that abut against the clamping seats are sleeved on the sliding rods; anti-slip protrusions are provided on the lower bottom surface of the second positioning seat; Explanation: By setting a clamping seat, the center of the refractory brick coincides with the center of the connection line between the two grinding rods, thus ensuring the consistency of the finishing of the two sides of the refractory brick.

[0008] Furthermore, a vertical plate is provided on the upper end face of the mounting bracket, and a swing seat is movably hinged on the vertical plate. The grinding rod and the drive motor are both mounted on the swing seat. Explanation: By using a swing seat to hinge the grinding rod to the upright plate, the grinding rod's trimming angle can be adjusted according to the inclination angle of the refractory brick splicing surface, thus improving the ease of use of this invention.

[0009] Furthermore, the swing seat is provided with a semi-circular plate that penetrates the vertical plate, the semi-circular plate is provided with scale markings, and the vertical plate is provided with a pin that can engage with the semi-circular plate. Explanation: By setting a semi-circular disk on the swing base, the scale markings on the semi-circular disk facilitate the control of the consistency of the tilt angle of the two swing bases.

[0010] Furthermore, a dust removal fan is installed on the outer wall of the U-shaped dust cover, and a dust collection box connected to the dust removal fan is installed on the inner wall of the U-shaped dust cover; a dust collection chamber connected to the dust removal fan is installed inside the base, and a sealing cover is movably hinged on the outer wall of the base at a position corresponding to the dust collection chamber. Note: By installing a dust removal fan, the dust generated during the finishing and polishing of refractory bricks can be cleaned up, providing a stable and reliable working environment for the staff.

[0011] The working principle of this utility model is as follows: In use, place the refractory brick to be repaired between the two clamping seats on the first positioning seat, and then press the operating lever to make the arc-shaped extrusion block push the extrusion rod to move downward along the mounting sleeve. At this time, the second positioning seat approaches the first positioning seat and clamps and fixes the refractory brick. Adjust the distance between the two grinding rods and the refractory brick by adjusting the screw, and adjust the tilt angle of the swing seat on the vertical plate. Finally, use the drive motor to drive the grinding rod to rotate. Push the operating lever to make the refractory brick move together with the first positioning seat and the second positioning seat between the two grinding rods to achieve the grinding of the splicing surface of the refractory brick.

[0012] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects: First, the structure of this utility model is reasonably designed. The refractory brick is clamped and fixed by the clamping action of the first positioning seat and the second positioning seat. Then, the refractory brick is pushed between the two grinding rods by the operating rod, which effectively improves the convenience and work efficiency when repairing the splicing surface of the refractory brick. Secondly, by movably setting two grinding rods on the worktable, and by freely adjusting the grinding angle of the grinding rods, this utility model not only makes it applicable to the repair of different types of refractory bricks, but also allows for the grinding of refractory bricks with different tilt angles. Third, this utility model provides a stable and reliable working environment for workers by installing a dust removal fan on the outer wall of the U-shaped dust cover and absorbing and purifying the dust generated during the repair and polishing of refractory bricks through the dust collection box.
