Description

Technical Field

[0001] This utility model relates to the field of refractory brick preparation technology, specifically to a refractory brick processing device for molten salt furnaces that enhances resistance to temperature differences. Background Technology

[0002] Refractory bricks are industrial materials specifically designed for high-temperature environments. They can operate stably for extended periods at extreme temperatures exceeding 1580℃ and are widely used in high-temperature equipment in industries such as metallurgy, building materials, and chemicals. Their core function is to resist thermal stress, chemical corrosion, and mechanical wear, ensuring the safe and efficient operation of furnaces, reaction towers, and other facilities.

[0003] Thermal shock resistance refers to the ability of refractory bricks to resist cracking, spalling, or failure caused by thermal stress under rapid temperature changes or temperature gradients. It is an important indicator for measuring the service life and reliability of refractory materials, and is especially crucial in industrial equipment that operates intermittently or undergoes frequent start-ups and shutdowns.

[0004] Isostatic pressing is a molding technique that uses a liquid or elastic medium to transmit uniform pressure, pressing refractory powder into a dense green body under high pressure. Its core advantage lies in the uniform pressure distribution, which can significantly improve the microstructure and mechanical properties of refractory bricks, thereby enhancing their thermal shock resistance.

[0005] Existing isostatic pressing equipment has low efficiency in isostatic pressing. Usually, the number of refractory bricks put into the hydraulic chamber is small. The small number of refractory bricks put in at one time will result in low molding efficiency and increase the energy consumption of refractory brick molding. Therefore, there is a need for refractory brick processing equipment that can improve the efficiency of isostatic pressing molding of refractory bricks. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a refractory brick processing device for molten salt furnaces that enhances the resistance to temperature differences.

[0007] The technical solution of this utility model is: a refractory brick processing device for molten salt furnace with enhanced resistance to temperature differences, including a support frame, a hydraulic chamber above the support frame, a hydraulic rod at the top of the hydraulic chamber, a sealing head at the bottom of the hydraulic rod, multiple hanging basket supports at the bottom of the sealing head, a refractory brick mold placed inside the hanging basket supports, the refractory brick mold filled with refractory brick powder, a liquid injection channel in the middle of the sealing head, a liquid injection pipe connected to the liquid injection channel above the sealing head, a sealing ring below the sealing head, and the end of the liquid injection pipe connected to a hydraulic pump.

[0008] Furthermore, the basket support includes a vertical connecting rod threadedly connected to the sealing head, and multiple baskets are provided on the inner and outer sides below the vertical connecting rod.

[0009] Note: Multiple placement baskets placed on the inner and outer sides of the vertical connecting rod can be used to place multiple refractory brick molds on a single hanging basket support. After a single pressurization of the hydraulic chamber, multiple refractory bricks can be pressed into shape.

[0010] Furthermore, a pressure sensor is provided at the bottom of the hydraulic chamber, and a display electrically connected to the pressure sensor is provided on the support frame.

[0011] Explanation: The hydraulic pressure in the hydraulic chamber is detected by a pressure sensor, and the pressure value in the hydraulic chamber is displayed on the monitor.

[0012] Furthermore, the refractory brick mold includes a lower refractory brick sleeve, and an upper refractory brick sleeve is glued above the lower refractory brick sleeve.

[0013] Explanation: The lower refractory brick sleeve is bonded to the upper refractory brick sleeve to seal the refractory brick powder.

[0014] Furthermore, the bottom of the hydraulic chamber is provided with a drain port, and a drain plug is threadedly connected to the drain port. Below the drain plug is a drain groove that is fixedly connected to the support frame.

[0015] Note: The liquid in the hydraulic chamber will become contaminated during long-term use. The contaminated liquid needs to be replaced. Conventional valves cannot withstand high pressure. The drain plug can be used to seal the drain port, and the outflowing liquid is discharged through the drain trough.

[0016] The beneficial effects of this utility model are:

[0017] This invention allows multiple refractory bricks to be isostatically pressed in a single process using a suspended basket support. As the hydraulic rod rises, it pulls out the suspended basket support, facilitating the placement and removal of the refractory brick molds, thus improving the molding efficiency of refractory bricks and reducing the energy consumption required for molding a single refractory brick. The refractory bricks formed by isostatic pressing using this invention have good thermal shock resistance. Attached Figure Description

[0023] like Figure 1 , Figure 2 As shown, a refractory brick processing device for molten salt furnace with enhanced resistance to temperature differences includes a support frame 1, a hydraulic chamber 2 above the support frame 1, a hydraulic rod 3 at the top of the hydraulic chamber 2, a sealing head 4 at the bottom of the hydraulic rod 3, multiple basket supports 5 at the bottom of the sealing head 4, a refractory brick mold 6 placed inside the basket supports 5, the refractory brick mold 6 filled with refractory brick powder 7, a liquid injection channel 41 in the middle of the sealing head 4, a liquid injection pipe 42 connected to the liquid injection channel 41 above the sealing head 4, a sealing ring 43 below the sealing head 4, and the end of the liquid injection pipe 42 connected to a hydraulic pump 8.

[0024] The hanging basket bracket 5 includes a vertical connecting rod 51 that is threadedly connected to the sealing head 4, and multiple placement baskets 52 are provided on the inner and outer sides below the vertical connecting rod 51.

[0025] Multiple placement baskets 52 placed on the inner and outer sides of the vertical connecting rod 51 can place multiple refractory brick molds 6 on a single hanging basket bracket 5. After the hydraulic chamber 2 is pressurized once, multiple refractory bricks can be pressed into shape.

[0026] like Figure 3 As shown, the refractory brick mold 6 includes a lower refractory brick sleeve 61, and an upper refractory brick sleeve 62 is bonded to the upper part of the lower refractory brick sleeve 61. Both the lower refractory brick sleeve 61 and the upper refractory brick sleeve 62 are made of polyurethane material.

[0027] The lower refractory brick sleeve 61 and the upper refractory brick sleeve 62 are bonded together using existing refractory mortar to seal the refractory brick powder.

[0028] Example 2:

[0029] The difference between this embodiment and embodiment 1 is that in this embodiment, a pressure sensor 21 is provided at the bottom of the hydraulic chamber 2, and a display 22 electrically connected to the pressure sensor 21 is provided on the support frame 1.

[0030] Compared to Example 1, this embodiment uses pressure sensor 21 to detect the hydraulic pressure in hydraulic chamber 2 and displays the pressure value in hydraulic chamber 2 using display 22.

[0031] Example 3:

[0032] The difference between this embodiment and embodiment 2 is that the bottom of the hydraulic chamber 2 in this embodiment is provided with a drain port 23, a drain plug 24 is threadedly connected to the drain port 23, and a drain groove 25 is provided below the drain plug 24 and fixedly connected to the support frame 1.

[0033] Compared to Example 2, in this embodiment, the liquid in the hydraulic chamber 2 will become contaminated during long-term use. The contaminated liquid needs to be replaced. Conventional valves cannot withstand high pressure. The drain plug 24 can block the drain port 23, and the outflowing liquid is discharged through the drain trough 25.

[0034] The working method of the refractory brick treatment equipment for molten salt furnace with enhanced resistance to temperature differences in Embodiment 3 above includes the following steps:

[0035] S1. Place the refractory brick raw material powder into the lower refractory brick sleeve 61 and compact it. Then, glue the upper refractory brick sleeve 62 onto the lower refractory brick sleeve 61. Then, place the refractory brick mold 6 into the placement basket.

[0036] S2. The sealing head 4 moves downward by the hydraulic rod 3, and the sealing head 4 comes into contact with the hydraulic chamber 2 to seal the hydraulic chamber 2. The hydraulic pump 8 injects liquid into the hydraulic chamber 2 through the injection pipe 42 and the injection channel 41. The pressure sensor 21 detects the liquid pressure in the hydraulic chamber and the display 22 shows the liquid pressure in the hydraulic chamber 2.

[0037] S3. By removing the drain plug 24, the liquid in the hydraulic chamber 2 flows into the drain tank 25, thereby replacing the liquid in the hydraulic chamber 2.

[0038] In the above embodiments, the hydraulic pump 8, pressure sensor 21, and display 22 are all commercially available products. As long as they can achieve the functions of this utility model, they are acceptable. Those skilled in the art can choose to use them based on common sense, and no special limitations are made here.
