Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for refractory brick production, specifically a refractory brick surface grinding and polishing device. Background Technology

[0002] Refractory bricks are a special building material with high temperature resistance and fire resistance. They are made from refractory materials through a specific formula and molding process, and are mainly used for the construction and maintenance of refractory structures and high-temperature equipment. The raw materials for refractory bricks typically include kaolin, quartz sand, and high-purity alumina. These raw materials have high temperature resistance and chemical stability, enabling them to maintain structural stability and durability under high-temperature environments. Based on different refractory temperatures and chemical compositions, refractory bricks can be divided into different grades and types, such as high-alumina refractory bricks, silicate refractory bricks, and magnesia-alumina refractory bricks. Specifically, the refractoriness of refractory bricks is usually between 1580℃ and 1770℃. They have specific shapes and sizes and can be cut and processed as needed. They are mainly used for lining various industrial kilns, such as blast furnaces, steel furnaces, coke ovens, glass melting furnaces, cement kilns, steam boilers, and other high-temperature kilns. However, during the production process, refractory bricks may have some surface defects, such as pores and oxide scale. These defects not only affect the appearance of the refractory bricks but may also affect their performance. Grinding and polishing can effectively remove these defects, making the surface of refractory bricks smoother and more uniform, thereby improving their overall quality. Furthermore, the roughness of the refractory brick surface affects its heat transfer performance; a rough surface increases thermal resistance and reduces heat transfer efficiency. Grinding and polishing can reduce the roughness of the refractory brick surface, improving its flatness and smoothness, thus facilitating heat transfer and enhancing the heat transfer effect. In high-temperature environments, the surface of refractory bricks is easily corroded by molten slag. A smooth surface reduces the direct contact area between molten slag and the refractory bricks, reducing the degree of slag corrosion. Therefore, improving the smoothness of the refractory brick surface through grinding and polishing helps enhance its slag resistance. Since refractory bricks are easily worn and corroded in high-temperature environments, grinding and polishing can form a hard oxide layer or protective layer on the refractory brick surface. The protective layer increases the hardness and wear resistance of refractory bricks, thereby extending their service life. As a building material, the appearance of refractory bricks plays an important role in the aesthetics of the entire building. Grinding and polishing can make the surface of refractory bricks brighter and smoother, improving their decorative effect. After firing, the surface of refractory bricks is often uneven, so it is necessary to manually hold the bricks and send them to the grinding wheel for surface grinding and polishing. However, this process generates a lot of dust and brick slag, which poses a potential threat to the health of the operators. At the same time, since the operators need to hold the refractory bricks directly close to the high-speed rotating grinding wheel for grinding, this operation method has significant safety hazards and may even cause safety accidents in severe cases. There may be technical means to solve the above problems in the existing technology, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a refractory brick surface grinding and polishing device, comprising: a device housing, a plurality of housing legs and a sandblasting storage box, wherein the plurality of housing legs are respectively installed on the device housing, the sandblasting storage box is installed on the device housing, a rotary clamping displacement structure is installed on the device housing, and a coordinated sandblasting and polishing component is installed on the device housing.

[0004] The rotary clamping displacement structure includes: a rotary power chamber, a rotary power rotor, a transmission gearbox, a connecting shaft, a rotary bearing seat, several clamping frames, and several brick clamping components.

[0005] The rotating power chamber is installed on the device housing, the rotating power rotor is installed in the rotating power chamber, the transmission gearbox is connected to the rotating power rotor, the connecting shaft is inserted into the transmission gearbox, the rotating bearing seat is fitted on the connecting shaft, a plurality of clamping frames are respectively installed on the rotating bearing seat, and a plurality of brick clamping assemblies are respectively installed on a plurality of clamping frames.

[0006] The brick clamping assembly includes: a clamping telescopic air rod, a guide displacement plate, a guide displacement groove, a pair of conductive displacement columns, several clamping slide rails, and a pair of brick clamping blocks;

[0007] The clamping telescopic air rod is installed inside the clamping frame. The guide displacement plate is connected to the clamping telescopic air rod. The guide displacement plate is provided with a pair of guide displacement grooves. A pair of conductive displacement columns are inserted into the pair of guide displacement grooves. The pair of conductive displacement columns are inserted into a pair of brick clamping blocks. A plurality of clamping slide rails are installed on the clamping frame. A pair of brick clamping blocks are installed on a plurality of clamping slide rails. A pair of connecting column sliding grooves are provided on the clamping frame. A pair of conductive displacement columns are inserted into the clamping frame through a pair of connecting column sliding grooves.

[0008] It should be noted that, as described above, the four shell legs stably support the device shell, driving the corresponding clamping telescopic air rods within the clamping frames to retract. This causes a pair of conductive displacement columns to slide within their respective guide displacement grooves, thereby pulling a pair of brick clamping blocks apart. The refractory brick to be polished is placed between the pair of brick clamping blocks. Then, the clamping telescopic air rods extend, causing the pair of conductive displacement columns to slide within their respective guide displacement grooves. This causes the pair of brick clamping blocks to move closer together until the refractory brick to be polished is tightly clamped. The adhesive pads on the brick clamping blocks ensure a more secure and firm clamping of the refractory brick. After multiple refractory bricks are clamped, the rotating power rotor in the rotating power chamber is driven, causing the transmission gearbox to rotate the connecting shaft and the rotating bearing seat. This causes the multiple clamping frames on the rotating bearing seat to rotate and shift within the device shell, facilitating subsequent polishing of the refractory bricks using the coordinated sandblasting and polishing components.

[0009] Preferably, the coordinated sandblasting and polishing assembly includes: a sand collection chamber, a sand transfer pipe, a displacement telescopic air rod, a nozzle mounting shaft, and an integrated nozzle;

[0010] The device housing has a sand collection chamber, the sand transmission pipe is connected to the sandblasting storage box, and the sand transmission pipe is connected to the integrated nozzle. The displacement telescopic air rod is installed in the device housing and is connected to the integrated nozzle through a rotating shaft. The nozzle mounting shaft is installed in the device housing and is connected to the integrated nozzle.

[0011] It should be noted that, as described above, the polishing sand in the sandblasting storage tank is drawn in by the integrated nozzle and guided by the sand transfer pipe, and finally sprayed onto the rotating clamping frame. By adjusting the length of the displacement telescopic air rod, the integrated nozzle can change its tilt angle based on the nozzle mounting shaft, thereby controlling and adjusting the polishing angle and effect. The falling sand is deposited in the sand collection chamber and then collected uniformly through the sand recovery port set on the sand collection chamber.

[0012] Preferably, the brick clamping block is provided with an adhesive pad;

[0013] Preferably, the sandblasting storage box is provided with a sand filling port;

[0014] Preferably, the sand collection bin is provided with a sand recovery port;

[0015] Preferably, the rotary power chamber is provided with a maintenance and inspection port. Beneficial effects

It has the following advantages: Compared with existing technologies, this refractory brick surface grinding and polishing device adopts a rotary clamping and displacement structure, which can properly fix multiple refractory bricks to be ground and polished, and achieve their rotational displacement. Subsequently, it is processed by an integrated spray head sandblasting and polishing system. This design effectively encapsulates the dust and sprayed sand generated during the entire grinding process, preventing them from escaping into the external environment. Therefore, it not only significantly improves grinding efficiency but also effectively protects the safety of operators, resulting in a substantial improvement in both the processing efficiency and safety of refractory bricks.
