[0025] See also Figure 1 and Figure 2 An embodiment of the present invention provides a spray heat exchange device for a stone cutting machine, comprising a plurality of spray heat exchange tubes 1. The spray heat exchange tubes 1 are provided with a plurality of heat exchange baffles 11, which divide the spray heat exchange tubes 1 into a plurality of heat exchange channels 12 and a plurality of spray channels 13. Each heat exchange channel 12 is respectively provided between adjacent spray channels 13. Spray ports 14 are penetrated at positions of the spray heat exchange tubes 1 corresponding to the spray channels 13. The same end of each adjacent spray heat exchange tube 1 is connected to a heat exchange connecting pipe 2, so that the adjacent heat exchange channels 12 are connected to form a continuous S-shaped channel, and a heat exchange water inlet 4 and a heat exchange water outlet 5 are respectively provided at both ends of the continuous S-shaped channel; wherein, the heat exchange water inlet 4 and the heat exchange water outlet 5 are used to connect the equipment to be cooled, and can perform cooling treatment on the equipment.

[0026] Both ends of the spray heat exchange tube 1 are respectively connected to the spray connecting pipe 3 , so that both ends of the spray channel 13 are connected to the spray connecting pipe 3 , and the spray connecting pipe 3 is provided with a spray water inlet 31 .

[0027] With the above-mentioned structure, through the setting of the heat exchange channel 12 and the spray channel 13 in the spray heat exchange tube 1 of the spray heat exchange device, when the coolant passes through the heat exchange channel 12, the heat will be conducted to the heat exchange baffle 11, so that the low-temperature water in the spray channel 13 can take away the heat, thereby realizing the cooling of the coolant in the heat exchange channel 12. At the same time, under the setting of the spray port 14, the water in the spray channel 13 can flow out through the spray port 14, so that it can be sprayed on the cutting position of the stone cutting machine, so as to play the role of cooling and chip removal at this position, thereby integrating spraying and heat exchange, reducing the equipment for cooling the coolant, thereby reducing the overall occupied space, eliminating the refrigeration equipment, and reducing manufacturing costs.

[0028] In one embodiment, see Figure 2 The number of heat exchange channels 12 is one less than the number of spray channels 13. In actual use, setting the total number of heat exchange channels 12 to one less than the number of spray channels 13 ensures that spray channels 13 are provided on both sides of the heat exchange channels 12, so that the spray channels 13 can fully remove the heat in the heat exchange channels 12, thereby ensuring the heat exchange efficiency of the heat exchange channels 12.

[0029] In one embodiment, see Figure 1 、 Figure 3 and Figure 4 One end of the spray connection pipe 3 is provided with a drain outlet 32. A valve can be provided at the drain outlet 32, and the valve can be used to control the opening and closing of the drain outlet 32. In actual use, the setting of the drain outlet 32 ​​can facilitate the cleaning of the spray connection pipe 3.

[0030] The spray port 14 is disposed on a side or bottom of the spray channel 13 away from the heat exchange channel 12. For the spray channels 13 located on the left and right sides of the spray heat exchange tube 1, the corresponding spray ports 14 are preferably disposed on the side of the spray channel 13, and the spray ports 14 are spaced a certain distance from the bottom of the spray channel 13. For the spray channel 13 located in the middle of the spray heat exchange tube 1, the corresponding spray ports 14 are disposed at the bottom of the spray channel 13. At the same time, the flow rate of the liquid flowing out of the spray ports 14 is lower than the flow rate of the spray channel 13, so that the liquid in the spray channel 13 has a certain hydraulic pressure, and the hydraulic pressure squeezes the liquid out of the spray ports 14 to ensure that the spray water can fill the entire spray channel 13, thereby ensuring the heat exchange effect between the spray channel 13 and the heat exchange channel 12. In actual use, the position of the spray ports 14 is limited to the side or bottom of the spray channel 13 to ensure that the liquid discharged from the spray ports 14 can be directly sprayed onto the stone cutting area to ensure the spraying effect.

[0031] In one embodiment, see Figure 1 、 Figure 3 and Figure 4 Multiple spray water inlets 31 are provided, and these multiple spray water inlets 31 are evenly distributed on the spray connecting pipe 3. A valve can be provided at the spray water inlet 31 to control the opening and closing of the spray water inlet 31. In actual use, providing multiple spray water inlets 31 on the spray connecting pipe 3 ensures uniform hydraulic pressure entering the spray channel 13 from the spray connecting pipe 3, thereby ensuring sufficient spray water in the spray channel 13 and preventing insufficient pressure in a local spray channel 13, which may lead to insufficient spray water. Example 2

[0032] See also Figures 1 to 5 An embodiment of the present invention further provides a spray heat exchange system for a stone cutting machine, comprising the above-mentioned spray heat exchange device for the stone cutting machine, a motor unit 6, a water tank 7 and a treatment pool 8, wherein the heat exchange outlet 5 of the spray heat exchange device is connected to the water tank 7, the water tank 7 is connected to the water inlet end of the motor unit 6 through a water pump, the water outlet end of the motor unit 6 is connected to the heat exchange inlet 4 of the spray heat exchange device, the treatment pool 8 is used to receive water sprayed from the spray port 14 of the spray heat exchange device, and the treatment pool 8 is connected to the spray inlet 31 of the spray heat exchange device through a water pump. Among them, both the water tank 7 and the treatment pool 8 can be equipped with water pumps, so that the coolant in the water tank 7 can be transported to the motor group 6, and passed into the heat exchange channel 12 of the spray heat exchange device through the heat exchange water inlet 4; the water pump in the treatment pool 8 can pass the spray water in the treatment pool 8 into the spray channel 13 through the spray water inlet 31 to exchange heat with the heat exchange channel 12, and at the same time, the spray water in the spray channel 13 is discharged through the spray port 14 to spray and cool down the stone cutting area and reduce dust. In the process of falling of the spray water, the heat carried away by the spray water will be dissipated into the air, so that the spray water naturally cools down and then falls into the treatment pool 8.

[0033] By adopting the above-mentioned structure, the coolant can be circulated in the heat exchange channel 12, the water tank 7 and the motor group 6 through the cooperation of the heat exchange channel 12, the motor group 6 and the water tank 7 of the spray heat exchange device. The spray water can be sprayed and circulated in the spray channel 13 and the treatment pool 8 through the cooperation of the spray heat exchange device. During the spraying process, the coolant in the heat exchange channel 12 is cooled by heat exchange, thereby concentrating the two cooling methods together, reducing the manufacturing cost, and reducing the occupied area of ​​the entire system.

[0034] In one embodiment, see Figure 3 、 Figure 4 and Figure 5The motor group 6 includes a plurality of motors 61, and the water inlet and outlet of the plurality of motors 61 are connected in parallel. The motors 61 of the motor group 6 can be water-cooled motors, i.e., motors with water cooling channels, which can be fed with cooling water to exchange heat with the motors to achieve water cooling of the motors. In actual use, through the plurality of parallel motors 61, the coolant can be delivered to the motor group 6 by the water pump in the water tank 7 so that the coolant can pass through the parallel motors 61 at the same time to ensure the cooling effect of the motors 61.

[0035] In one embodiment, see Figure 3 and Figure 4 The water tank 7 is provided with a water replenishment port 71 for connecting to an external water supply pipe. A corresponding water replenishment port may also be provided on the treatment tank 8 to facilitate replenishment of spray water. In actual operation, the provision of the water replenishment port 71 allows the water tank 7 to replenish lost coolant to ensure the cooling effect on the motor unit 6.

[0036] In one embodiment, see Figure 4 and Figure 5 The treatment tank 8 is a still water tank or a filtration tank. In actual use, when the treatment tank 8 is a still water tank, the spray water mixed with the dust generated during the stone cutting process is sedimented by sedimentation. When the treatment tank 8 is a filtration tank, a corresponding filter is provided in the treatment tank 8 to filter the particles formed by the spray water mixed with the dust generated during the stone cutting process, thereby ensuring the cleanliness of the spray water in the treatment tank 8 when the water pump in the treatment tank 8 is used.
