Abstract
Description
Technical Field
[0001] This utility model relates to the field of hollow brick curing technology, and in particular to a special steam curing equipment for coal gangue hollow bricks. Background Technology
[0002] The main component of coal gangue hollow bricks is coal gangue, which is a solid waste discharged during the coal mining and washing process. Its main components are Al2O3 and SiO2, and it also contains varying amounts of Fe2O3, CaO, MgO, Na2O, K2O, P2O5, SO3 and trace rare elements (gallium, vanadium, titanium, cobalt). The production cost of coal gangue bricks is lower than that of ordinary clay bricks. Using coal gangue to make bricks not only saves land but also consumes mine waste. It is an environmentally friendly and low-carbon building material.
[0003] In the production process of coal gangue hollow bricks, one of the important steps is the steam curing of the bricks. Traditional curing devices simply spray steam onto the surface of the bricks, which results in poor steam curing effect. In addition, excess steam is usually discharged directly to the outside during the curing process, which easily leads to steam waste. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a special steam curing device for hollow coal gangue bricks. During use, this curing device utilizes simultaneous internal and external steam injection to improve the curing effect, and excess steam can be recovered, reducing water waste.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A steam curing device for hollow coal gangue bricks includes a shell with an inner cavity. A diversion groove is formed at the bottom of the inner cavity, and a baffle plate is installed at the opening of the diversion groove. A steam curing mechanism includes a steam generator mounted on the right side of the shell, with its outlet extending to the bottom of the diversion groove. Multiple sets of vent holes are evenly spaced on the baffle plate, each set consisting of four first holes and four second holes. A recovery mechanism is also included to recover the steam.
[0007] Preferably, a sealing door is installed on the front side of the housing.
[0008] Preferably, the sealed door is equipped with a pull handle.
[0009] Preferably, the recycling mechanism includes a water tank fixedly connected to the upper end of the shell, and the inner top space of the inner cavity is connected to a connecting pipe, the other end of which is connected to the inner bottom of the water tank.
[0010] Preferably, the water tank is filled with ice-containing water, the top of the water tank has an inlet, the bottom of the water tank is connected to the outside through a drain outlet, and a manual valve is installed in the drain outlet.
[0011] Preferably, an air pump is installed on the left side of the housing, the air pump's outlet end is connected to an air outlet pipe, and the other end of the air outlet pipe is connected to the inside of the diversion groove.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] 1. It is equipped with a first hole and a second hole. The air discharged from the first hole comes into contact with the inner hole of the hollow brick, while the steam discharged from the second hole comes into contact with the outer side of the hollow brick. In this way, the maintenance work can be carried out in actual use, and the inner and outer parts can be maintained at the same time, which can improve the maintenance effect.
[0014] 2. It is equipped with a water tank filled with low-temperature water containing ice. Excess steam will enter the water tank through a connecting pipe, and after contacting the low-temperature water, it will condense into water and be collected in the water tank. This can realize the recovery of excess steam and reduce the waste of water resources.
[0015] 3. An air pump is installed. After maintenance is completed, starting the air pump will not only prevent steam from spreading outwards and affecting the staff by directly opening the sealed door, but also further improve the recovery rate of excess steam.
[0016] In summary, this maintenance equipment not only effectively improves the maintenance results during the maintenance process, but also recovers excess steam, reducing water waste, and prevents steam from spreading outwards and affecting workers when the sealed door is opened.

[0024] Reference Figures 1-3 A steam curing equipment for hollow coal gangue bricks includes a shell 1, an inner cavity 11 inside the shell 1, a diversion groove 12 at the bottom of the inner cavity 11, a partition 13 at the opening of the diversion groove 12, a sealing door 5 on the front side of the shell 1, and a handle 6 on the sealing door 5.
[0025] This also includes a steam curing mechanism, which includes a steam generator 2 installed on the right side of the housing 1. The steam generator, also called a steam heat source machine, is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. During use, it generates steam. The steam generator 2's outlet extends to the inner bottom of the distribution trough 12. Multiple sets of vent holes are evenly spaced on the partition plate 13. Each set of vent holes consists of four first holes 14 and four second holes 15. The first holes 14 and second holes 15 are as follows... Figure 3 As shown, the device is designed for four-hole coal gangue hollow bricks on the market, where the four first holes 14 correspond to the four inner holes of the hollow brick, and the four second holes 15 correspond to the outer side of the hollow brick.
[0026] It also includes a recovery mechanism for recovering steam. The recovery mechanism includes a water tank 3 fixedly connected to the upper end of the shell 1. The inner top space of the inner cavity 11 is connected to a connecting pipe 10. The other end of the connecting pipe 10 is connected to the inner bottom of the water tank 3. The water tank 3 is filled with ice-containing water. The inner top of the water tank 3 has a discharge port 4. The inner bottom of the water tank 3 is connected to the outside through a drain port 9. A manual valve is installed in the drain port 9.
[0027] An air pump 7 is installed on the left side of the housing 1. The air outlet of the air pump 7 is connected to an air outlet pipe 8, and the other end of the air outlet pipe 8 is connected to the inside of the diversion groove 12.
[0028] In this utility model, when in specific use, first open the sealing door 5, then stack the hollow bricks on the upper end of the partition 13 so that the four inner holes of the hollow bricks correspond to the four first holes 14, and then stack them vertically. This action is performed in sequence. When steam curing, after closing the sealing door 5, start the steam generator 2.
[0029] After the steam generator 2 is started, the generated steam will be injected into the diversion tank 12 and finally discharged from multiple first holes 14 and second holes 15. In this way, the steam discharged from the first holes 14 contacts the inner hole of the hollow brick, while the steam discharged from the second holes 15 contacts the outer side of the hollow brick. In actual use, the maintenance work can be carried out, and the inner and outer parts can be maintained at the same time, which can improve the maintenance effect.
[0030] Excess steam will enter the water tank 3 through the connecting pipe 10, and after contacting the low temperature water, it will condense into water and be collected in the water tank 3.
[0031] After maintenance is completed, the steam generator 2 can be turned off and the air pump 7 can be started at the same time. After the air pump 7 is started, the high-pressure air generated enters the diversion tank 12 and is finally discharged from multiple first holes 14. The high-pressure air will carry the residual steam in the inner cavity 11 into the water tank 3 through the connecting pipe 10 to collect the residual steam. This not only avoids the steam from spreading outwards and affecting the staff by directly opening the sealing door 5, but also further improves the recovery rate of excess steam.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
