Description

Technical Field

[0001] This utility model relates to the technical field of heat recovery equipment for firing furnaces, and in particular to a waste heat recovery structure for a refractory brick firing furnace. Background Technology

[0002] After the refractory bricks are fired, the furnace still has a high temperature, but it is no longer high enough to fire the bricks. It would be a great pity not to make use of it. Utility Model Content

[0003] This invention aims to overcome the shortcomings of existing technologies where the waste heat inside the firing furnace cannot be utilized, and provides a waste heat recovery structure for refractory brick firing furnaces that can utilize the waste heat of the firing furnace for daily life.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A waste heat recovery structure for a refractory brick firing furnace includes:

[0006] The firing furnace is part of the waste heat recovery structure;

[0007] A water pipe is placed at the top inside the firing furnace, with both ends of the water pipe extending out from the top inside the firing furnace and positioned outside the firing furnace. The water pipe runs in a U-shape at the top inside the firing furnace.

[0008] Several fixing clips are evenly distributed on the top surface of the firing furnace. The upper end face of the fixing clip is fixedly connected to the top surface of the firing furnace. The cross-sectional shape of the fixing clip is C-shaped. The shape of the C-shaped groove of the fixing clip corresponds to the cross-sectional shape of the water pipe. The water pipe is placed in the C-shaped groove of the fixing clip and is engaged with the fixing clip through the C-shaped groove of the fixing clip.

[0009] A water storage tank is located behind the firing furnace, and one end of the water pipe is connected to the interior of the water storage tank.

[0010] The placement trough is located on the rear end face of the water storage tank;

[0011] A water tap is placed on the rear end face of the water tank. The water tap is fixedly connected to the water tank and communicates with the interior of the water tank.

[0012] When in use, after the kiln stops firing bricks, water is allowed to flow through the water pipe. The water pipe is fixed to the top of the kiln with a clamp. With hot air rising, the water pipe at the top of the kiln can make better use of the residual heat. The U-shaped direction of the water pipe can increase the contact area, allowing for more and faster heating of water. The heated water enters the water storage tank. Workers can place items that need to be heated in the storage tank and use the heat of the hot water to heat them. When hot water is needed, the water tap can be turned on to draw hot water from the storage tank. It is very convenient and achieves the purpose of using the residual heat of the kiln for daily life.

[0013] Preferably, a water pump is installed inside the water pipe, and the water pump is located at one end of the water pipe near the water tank, with the water pump fixedly connected to the water pipe. The water pump facilitates the water pipe in pumping water to a higher position.

[0014] Preferably, the water tank has an internal insulation layer, which is fixedly connected to the tank. The insulation layer prevents the water temperature inside the tank from dropping rapidly, thus increasing the efficiency of heating the items.

[0015] Preferably, the water tank is provided with an anti-scalding layer, which covers the outer surface of the water tank and is fixedly connected to it. The anti-scalding layer prevents personnel from being scalded by contact with the water tank.

[0016] Preferably, the water tank has a cover plate on its rear end face, which covers the opening of the placement slot, and one side of the cover plate is hinged to the water tank. The cover plate can cover the placement slot, reducing heat dissipation inside the placement slot.

[0017] Preferably, the inner bottom surface of the water tank is higher at the front and lower at the back, and the outlet of the water tap is located at the lowest point of the inner bottom surface of the water tank. This design allows hot water to flow directly through the water tap, preventing water accumulation in the water tank.

[0018] The beneficial effects of this utility model are: it can utilize the waste heat of the furnace for daily life purposes; the water pump facilitates the pumping of water to a higher place; the insulation layer ensures that the water temperature in the water tank does not drop rapidly, increasing the heating efficiency of items; the anti-scalding layer prevents people from being scalded by contact with the water tank; the cover plate can cover the placement slot, reducing heat loss from the placement slot; the inner bottom of the water tank allows hot water to come out directly through the tap, and no water will remain in the water tank.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 6 In one embodiment, a waste heat recovery structure for a refractory brick firing furnace includes: a water pipe 2 placed at the top of the firing furnace 1, with both ends of the water pipe 2 extending from the top of the firing furnace 1 and positioned outside the firing furnace 1, the water pipe 2 having a U-shaped orientation at the top of the firing furnace 1; several fixing clips 3 evenly distributed on the top surface of the firing furnace 1, the upper end face of the fixing clips 3 being fixedly connected to the top surface of the firing furnace 1, the cross-sectional shape of the fixing clips 3 being C-shaped, the C-shaped groove shape of the fixing clips 3 corresponding to the cross-sectional shape of the water pipe 2, the water pipe 2 being placed in the C-shaped groove of the fixing clips 3, and the water pipe 2 being snapped into the fixing clips 3 through the C-shaped groove of the fixing clips 3; a water tank 4 placed at the rear of the firing furnace 1, one end of the water pipe 2 communicating with the interior of the water tank 4; a placement groove 5 placed on the rear end face of the water tank 4; and a water tap 6 placed on the rear end face of the water tank 4, the water tap 6 being fixedly connected to the water tank 4 and communicating with the interior of the water tank 4.

[0029] like Figure 3 and Figure 7 As shown, the water pump 7 is placed near the end of the water pipe 2 near the water storage tank 4, and the water pump 7 is fixedly connected to the water pipe 2.

[0030] like Figure 7 As shown, the water tank 4 has an insulation layer 8 inside the tank wall for keeping hot water warm.

[0031] like Figure 7 As shown, the anti-scalding layer 9 covers the outer surface of the water tank 4 to prevent people from being scalded.

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, there is a cover plate 10 on the rear end face of the water tank 4. The cover plate 10 covers the opening of the placement slot 5, and one side of the cover plate 10 is connected to the water tank 4 by a hinge.

[0033] like Figure 3 As shown, the inner bottom surface of the water tank 4 is higher in the front and lower in the back. The outlet of the water tap 6 is located at the lowest point of the inner bottom surface of the water tank 4, so that the water flows towards the water tap 6 when it is discharged, reducing the accumulation of water in the water tank 4.

[0034] In use, after the firing furnace 1 stops firing bricks, water is pumped through the water pipe 2 using the water pump 7. The water pipe 2 is fixed to the top of the firing furnace 1 by the fixing clamp 3. With hot air rising, the water pipe 2 at the top of the firing furnace 1 can make full use of the residual heat. The U-shaped direction of the water pipe 2 can increase the contact area, so that more water is heated and faster. The heated water enters the water storage tank 4. The placement trough 5 has no heat insulation layer 8 and anti-scalding layer 9. Workers can place the items that need to be heated in the placement trough 5 and heat them with the heat of the hot water. When heating, the placement trough 5 is covered with the cover plate 10. When hot water is needed, the water tap 6 can be opened to draw hot water from the water storage tank 4. It is very convenient and achieves the purpose of using the residual heat of the firing furnace for daily life.
