Description

Technical Field

[0001] This invention relates to the field of magnesia-carbon brick blank testing technology, specifically a precision testing structure for corrosion-resistant magnesia-carbon brick blanks used in high-temperature zones. Background Technology

[0002] Magnesia-carbon bricks are non-burning composite refractory materials made from high-melting-point alkaline oxide magnesium oxide (melting point 2800℃) and high-melting-point carbon materials that are difficult to be wetted by slag, with the addition of various non-oxide additives and bonded with carbonaceous binders. When testing magnesia-carbon brick blanks, the resistance of the blanks is tested. This precision testing structure is used to test the resistance of magnesia-carbon brick blanks.

[0003] When inspecting magnesia-carbon brick blanks, due to the simple inspection structure and limited space at the end, magnesia-carbon bricks are usually placed on a rack. Retrieving and storing magnesia-carbon bricks from the rack is not convenient enough, does not make full use of the space at the end of the inspection structure, and the travel distance for retrieving and storing magnesia-carbon bricks during the inspection process is also relatively large, which is not time-saving, labor-saving and convenient. Summary of the Invention

[0004] The purpose of this invention is to provide a precision inspection structure for corrosion-resistant magnesia-carbon brick blanks in high-temperature zones, in order to solve the problems mentioned in the background art. When inspecting magnesia-carbon brick blanks, due to the simple inspection structure and limited space at the end, magnesia-carbon bricks are generally placed on a rack. Retrieving and storing magnesia-carbon bricks from the rack is not convenient, does not fully utilize the space at the end of the inspection structure, and the travel distance for retrieving and storing magnesia-carbon bricks during the inspection process is also relatively large, which is not time-saving, labor-saving, or convenient.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a precision inspection structure for corrosion-resistant magnesia-carbon brick blanks in high-temperature zones, comprising a U-shaped support, a top plate rotatably connected to the support, four supports arranged in a ring on the upper end of the top plate, a pair of L-shaped support plates fixed to the front wall of the support, a horizontal plate fixed to the top wall of the support plates, a cylinder fixed to the top of the horizontal plate, a pneumatic rod connected to the lower end of the cylinder, a lower pressure roller fixed to the lower end of the pneumatic rod, and L-shaped support plates fixed to the side walls of the support plates and the lower wall of the horizontal plate, forming an opening between the support plates, the horizontal plate, and the support plates for supporting the magnesia-carbon brick blanks.

[0006] Preferably, a rotating column is fixedly connected to the upper wall of the center of the bottom of the bracket, and a top plate is rotatably connected to the upper end of the rotating column. A sliding groove is opened at the bottom wall of the top plate, and sliders fixedly connected to the top ends of both sides of the bracket are movably connected in the sliding groove.

[0007] Preferably, a circular groove is formed at the bottom edge of the top plate, and a pair of semi-circular connecting discs are threaded into the groove.

[0008] Preferably, there are two connecting disks, each of which is semi-circular in shape and has a cavity on its upper wall.

[0009] Preferably, the inner ring end wall of the connecting disk is provided with a locking hole that communicates with the disk cavity, a locking pin is inserted into the locking hole, and a connecting piece is fixed to the end wall of the locking pin.

[0010] Preferably, the top plate has an upper opening on its upper end wall, and four drains connected to the upper opening are arranged in a ring on the end wall of the top plate.

[0011] Preferably, the support includes four concave-shaped bases fixed to the upper wall of the top plate near the upper opening, and a pair of cylindrical support rollers rotatably connected within the concave openings of the bases for supporting the magnesia-carbon brick blanks.

[0012] Preferably, the support further includes a screw threaded to the bottom of the base side wall, an L-shaped support plate rotatably connected to the end wall of the screw, and a clamping piece fixed to the top end wall of the support plate for clamping the magnesia-carbon brick blank.

[0013] Preferably, the base has an L-shaped limiting strip that is fixed to the top end wall and movably connected to the support plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In this invention, a magnesia-carbon brick blank is placed on a pair of support rollers, and then the screw is rotated. The screw is displaced, which drives the support plate to move laterally, bringing the two support plates closer together. The clamping plates hold the end wall of the magnesia-carbon brick and limit its position. When the support plate is displaced, the support plate and the limiting strip move together, making the displacement of the support plate more stable. The cylinder runs, and the air rod drives the lower pressure roller to move down and press on the magnesia-carbon brick blank to compress the magnesia-carbon brick. The invention detects whether the magnesia-carbon brick is broken, bent, or otherwise damaged, and further tests the resistance of the magnesia-carbon brick.

[0016] 2. During use, the cylinder and the lower pressure roller are located in the front area of ​​the support. When the top plate rotates, a pair of support rollers at the top of the top plate rotate to this area and are located directly below the lower pressure roller. The support rollers support the magnesia-carbon bricks, and the lower pressure roller presses down to detect the magnesia-carbon bricks. Rotating the top plate causes the four pairs of support rollers at the top of the top plate to alternately switch positions in sequence, thereby alternating the positions of the magnesia-carbon bricks. This facilitates rapid detection and processing of the magnesia-carbon brick structure. After the magnesia-carbon bricks are detected, they are rotated out of the detection station, making it convenient to change the magnesia-carbon brick material while detecting it.

[0017] 3. When the top plate rotates, the sliding groove at the bottom of the top plate moves with the slider, making the top plate more stable and providing better support during rotation;

[0018] 4. During the feeding and testing of magnesia-carbon bricks, the generated debris will fall into the upper opening, seep down through the sluice gate, and fall into the cavity of the connecting plate. After the cavity of the connecting plate is full of debris, rotate the two connected plates that are spliced ​​together. The two connecting plates will move together with the groove at the bottom end wall of the top plate through threaded transmission, which facilitates the disassembly and assembly of the two connecting plates and the emptying of the connecting plates and the debris in the cavity. The two connecting plates are connected by a locking hole and a locking pin. Remove the locking pin at the locking hole to separate the two connecting plates so that they can be processed separately.

[0019] 5. A horizontal plate is fixed at the support plate and the support plate. The end wall of the horizontal plate is used to hold the magnesia-carbon brick blank, which facilitates the quick access and storage of the magnesia-carbon brick blank. As a result, the material replacement efficiency is higher during testing. Attached Figure Description

[0029] Please see Figure 1-5 The present invention provides a technical solution: a precision inspection structure for corrosion-resistant magnesia-carbon brick blanks in high-temperature zones, including a bracket 1 in the shape of a concave character, a top plate 3 rotatably connected to the bracket 1, four supports distributed in a ring at the upper end of the top plate 3, a pair of L-shaped support plates 20 fixed to the front wall of the bracket 1, a horizontal plate 21 fixed to the top end wall of the support plate 20, a cylinder 23 fixed to the top of the horizontal plate 21, a pneumatic rod 24 connected to the lower end of the cylinder 23, a lower pressure roller 25 fixed to the lower end of the pneumatic rod 24, and L-shaped support plates 22 fixed to the side wall of the support plate 20 and the lower end wall of the horizontal plate 21, with an opening for supporting the magnesia-carbon brick blanks formed between the support plate 22, the horizontal plate 21, and the support plate 20.

[0030] A rotating column 2 is fixedly connected to the upper wall of the bottom center of the bracket 1. A top plate 3 is rotatably connected to the upper end of the rotating column 2. A sliding groove 18 is opened at the bottom wall of the top plate 3. A slider 19 fixedly connected to the top ends of both sides of the bracket 1 is movably connected in the sliding groove 18.

[0031] A circular groove 4 is provided at the bottom edge of the top plate 3. A pair of semi-circular connecting discs 5 are threaded into the groove 4. There are two connecting discs 5. The connecting discs 5 are semi-circular in shape. A disc cavity 6 is provided on the upper wall of the connecting disc 5.

[0032] A locking hole 7, which communicates with the cavity 6, is provided at the inner ring end wall of the connecting plate 5. A locking pin 8 is inserted into the locking hole 7. A connecting piece 9 is fixed to the end wall of the locking pin 8. An upper opening 16 is opened on the upper end wall of the top plate 3. Four drains 17, which communicate with the upper opening 16, are distributed in a ring on the end wall of the top plate 3.

[0033] The support includes four concave-shaped bases 10 fixed to the upper wall of the top plate 3 near the upper opening 16, arranged in a ring shape; a pair of cylindrical support rollers 11 rotatably connected to the concave openings of the bases 10 for supporting the magnesia-carbon brick blanks; the support also includes a screw 12 threaded to the bottom of the side wall of the bases 10; an L-shaped support plate 13 rotatably connected to the end wall of the screw 12; and a clamping piece 15 fixed to the top end wall of the support plate 13 for clamping the magnesia-carbon brick blanks.

[0034] An L-shaped limiting strip 14, which is movably connected to the support plate 13, is fixed to the top end wall of the base 10.

[0035] In summary, the high-temperature zone uses corrosion-resistant magnesia-carbon brick blanks for precise inspection. When in use...

[0036] The magnesia-carbon brick blank is placed on a pair of support rollers 11, and then the screw 12 is rotated. The screw 12 moves and drives the support plate 13 to move laterally, so that the two support plates 13 are close together. The clamping piece 15 clamps the end wall of the magnesia-carbon brick and limits the magnesia-carbon brick. When the support plate 13 moves, the support plate 13 and the limiting strip 14 move together, making the support plate 13 more stable when it moves.

[0037] When cylinder 23 is in operation, the air rod 24 drives the lower pressure roller 25 to move down and press it onto the magnesia-carbon brick blank to compress the magnesia-carbon brick and detect whether the magnesia-carbon brick is broken, bent or otherwise damaged. In addition, the resistance of the magnesia-carbon brick is tested.

[0038] During use, the cylinder 23 and the lower pressure roller 25 are located in the front area of ​​the bracket 1. When the top plate 3 rotates, a pair of support rollers 11 at the top of the top plate 3 rotate to this area and are located directly below the lower pressure roller 25. The support roller 11 supports the magnesia-carbon brick, and the lower pressure roller 25 presses down to detect the magnesia-carbon brick.

[0039] Obviously, rotating the top plate 3 causes the four pairs of support rollers 11 at the top of the top plate 3 to alternately switch positions in turn, thereby causing the magnesia-carbon bricks to be alternately switched positions, so as to facilitate the rapid detection and processing of the magnesia-carbon brick structure. After the magnesia-carbon bricks are detected, they are turned out of the detection station, which makes it convenient to change the magnesia-carbon brick material while detecting.

[0040] When the top plate 3 rotates, the sliding groove 18 at the bottom of the top plate 3 moves with the slider 19, making the top plate 3 more stable and providing better support when rotating.

[0041] During the feeding and testing of magnesia-carbon bricks, the generated debris falls into the upper opening 16, seeps down through the drain 17, and falls into the cavity 6 of the connecting plate 5. After the cavity 6 of the connecting plate 5 is full of debris, the two connected plates 5 are rotated together. The two connecting plates 5 are moved together by the threaded transmission of the groove 4 at the bottom end wall of the top plate 3, which facilitates the disassembly and assembly of the two connecting plates 5 and the emptying of the debris in the cavity 6. The two connecting plates 5 are connected by the insertion of the locking hole 7 and the locking pin 8. The locking pin 8 at the locking hole 7 is removed to separate the two connecting plates 5 so that they can be processed separately.

[0042] A horizontal plate 21 is fixedly connected to the support plate 20 and the support plate 22. The end wall of the horizontal plate 21 is used to hold the magnesia-carbon brick blank, which facilitates the quick access and storage of the magnesia-carbon brick blank. As a result, the material replacement efficiency is higher during testing.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
