Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a cement clinker cooler. Background Technology

[0002] After exiting the kiln, cement clinker reaches a high temperature (typically above 1000℃), requiring rapid cooling via a cooler to recover residual heat and improve clinker quality. Chinese Patent CN222257738U discloses a cement clinker cooling device, including a grate cooler body. A semi-toothed gear is installed at the output end of a second motor. Two limiting frames are installed on the inner wall of the grate cooler body, and one end of each of the two springs is connected to a connecting rod. After falling onto the conveying device, the cement clinker is transported to the tail end. During this process, the second motor is activated, causing wedge blocks to move and guide the cement clinker. The clinker is then separated by partitions and falls from the tail end of the wedge blocks, creating gaps between the cement clinker for uniform cooling by cold air, preventing stacking, and thus ensuring more uniform cooling of the cement clinker inside the grate cooler, improving cooling efficiency.

[0003] However, the above-mentioned publicly available solutions have the following shortcomings: although structures such as wedge blocks can cool down cement clinker, the residual heat of cement clinker cannot be recovered and utilized, resulting in a certain waste of resources. Utility Model Content

The inlet pipe and the drain pipe are respectively installed on the left and right side walls of the cooling box, and the output end of the drain pipe is connected to an insulation box.

[0006] Preferably, the cooling seat includes a limiting frame that is vibratoryly connected to the inner wall of the cooling box; and a grate plate that is installed at the bottom end of the limiting frame, with a serpentine cavity disposed inside the grate plate and grate holes disposed through the grate plate.

Detailed Implementation

[0017] Example 1

[0018] like Figures 1 to 4 As shown, the present invention proposes a cement clinker cooler, including a cooling box 1, a cooling seat, and a serpentine cavity 203. Multiple sets of cooling seats are arranged, and these sets are vibratingly installed inside the cooling box 1 from top to bottom. Multiple sets of grate holes 202 are evenly distributed at the bottom end of each cooling seat. The serpentine cavity 203 is located inside the bottom end of the cooling seat and distributed among the multiple sets of grate holes 202. Connecting valves 204 are installed at both the input and output ends of the serpentine cavity 203. One set of connecting valves 204 is connected to an inlet pipe 205 via a flexible hose, and the other set of connecting valves 204 is connected to a drain pipe 206 via a flexible hose. The inlet pipe 205 and the drain pipe 206 are respectively installed on the left and right side walls of the cooling box 1. The input end of the inlet pipe 205 is connected to an external cooling water supply mechanism, and the output end of the drain pipe 206 is connected to an insulation box 4.

[0019] Furthermore, the cooling seat includes a limiting frame 2 and a grate 201; the limiting frame 2 is vibratoryly connected to the inner wall of the cooling box 1, and multiple sets of uprights are evenly installed on the limiting frame 2. The uprights are installed on the inner wall of the cooling box 1, and two sets of springs are sleeved on the uprights. The springs are connected to the uprights and the limiting frame 2. A vibration motor 207 is provided at the bottom of the cooling seat. The vibration motor 207 is started by the controller to drive the limiting frame 2 to vibrate. Under the action of multiple sets of springs, the cooling seat vibrates up and down along the uprights, which has the effect of vibrating and dispersing the cement clinker falling in the cooling seat, so that the auxiliary cement clinker falls down along the grate hole 202; the grate 201 is installed at the bottom of the limiting frame 2, the serpentine cavity 203 is set inside the grate 201, the grate hole 202 is set through the grate 201, and the connecting valve 204 is installed on the side wall of the grate 201;

[0020] Furthermore, the multiple sets of grate holes 202 at the bottom of the two adjacent sets of cooling seats are staggered to improve the vibration and dispersing effect on the cement cooling material, and facilitate sufficient basic heat exchange with cold air and cooling water.

[0021] Furthermore, the outer wall of the cooling box 1 and the outer wall of the first exhaust duct 303 are provided with a first insulation plate to prevent a large amount of heat loss and waste.

[0022] In this embodiment, cement clinker is poured into the cooling tank 1 through the inlet valve and the valve is closed. Cooling water is supplied to multiple sets of serpentine cavities 203 via an external cooling water supply mechanism connected to the inlet pipe 205. Simultaneously, a vibration motor 207 is activated to drive the cooling seats to vibrate along the inner wall of the cooling tank 1. The vibration of the multiple cooling seats disperses the cement clinker, which then falls layer by layer through multiple grate holes 202 and is further dispersed by the vibration of the next cooling seat. When the cement clinker comes into contact with the grate plate 201… The cooling water flowing in the serpentine cavity 203 can quickly absorb the heat in the cement clinker. The serpentine cavity 203 can prolong the contact time between the cooling water and the cement clinker, thereby improving the cooling effect. The water that has absorbed heat enters the insulation box 4 through the drain pipe 206 for later use. It should be noted that the insulation box 4 is equipped with a temperature sensor to monitor the water temperature. The heated water can be recycled to avoid waste. The cement clinker that has been cooled in stages is discharged from the discharge port at the bottom of the cooling box 1 into the receiving box.

[0023] Example 2

[0024] like Figure 2 and Figure 3 As shown, the cement clinker cooler proposed in this utility model, compared with Embodiment 1, further includes a cooling mechanism. The cooling mechanism consists of a distribution pipe 301 distributed below the cooling seat, an air inlet pipe 3, multiple sets of air outlet pipes 302 installed on the distribution pipe 301, and a first row of air pipes 303 installed at the air outlet at the top of the cooling box 1. Multiple sets of distribution pipes 301 are provided, and the input ends of the multiple distribution pipes 301 are connected to the output ends of the air inlet pipes 3. The air inlet pipes 3 are installed on the side wall of the cooling box 1, and their input ends are connected to an external cold air supply mechanism. The distribution pipes 301 are connected to the inner wall of the cooling box 1 through support members, and the air outlet pipes 302 are vertical. Installed on the distribution pipe 301 and corresponding to the grate hole 202 at the bottom of the cooling seat, the air outlet pipe 302 is equipped with a one-way valve to prevent a large amount of powder from the cement clinker from entering the distribution pipe 301 and causing blockage. The first exhaust pipe 303 is equipped with a first fan to assist hot air into the insulation chamber 401. The insulation box 4 consists of an outer layer, an insulation chamber 401 and an inner layer. A second insulation board is installed between the inner layer of the insulation box 4 and the insulation chamber 401 to prevent a large amount of heat loss and waste. The output end of the first exhaust pipe 303 is connected to the insulation chamber 401 in the insulation box 4. The output end of the insulation chamber 401 is equipped with a second exhaust pipe 402.

[0025] Furthermore, a filter assembly 304 is provided at the input end of the first exhaust duct 303. The filter assembly 304 consists of a cyclone separator and a bag filter, which is used to filter dust in cement clinker. A second fan is provided on the first exhaust duct 303 and near the filter assembly 304. A solenoid valve is provided on one side of the second fan. By periodically closing the solenoid valve and then starting the second fan, the filter assembly 304 can be backflushed to prevent the filter holes from becoming clogged.

[0026] In this embodiment, an external cold air supply mechanism is connected to the air inlet pipe 3 to deliver cold air to the multi-group flow pipe 301. It should be noted that a wind speed adjustment mechanism is provided between the cold air supply mechanism and the air inlet pipe 3 to adjust the wind speed and prevent the powder in the cement clinker from flying to the outside of the cooling box 1 due to excessive wind speed. The cold air is blown upward from the multi-group air outlet pipe 302 and penetrates the cement clinker layer upward from the multi-group grate holes 202 to achieve counter-current heat exchange. After absorbing heat, the cold air is filtered by the filter component 304 and then discharged into the insulation chamber 401 through the first exhaust pipe 303 to further insulate the insulation box 4 and prevent a large loss of the temperature of the hot water buffered inside the insulation box 4.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
