A spray heat exchange device and system for a stone cutting machine

Abstract

This invention provides a spray heat exchange device and system for a stone cutting machine, comprising multiple spray heat exchange pipes, with a heat exchange connecting pipe connected to the same end of each adjacent spray heat exchange pipe, and spray connecting pipes connected to both ends of each spray heat exchange pipe. Through the above structure, by setting up heat exchange channels and spray channels in the spray heat exchange pipes of the spray heat exchange device, when the coolant passes through the heat exchange channels, heat is conducted to the heat exchange baffles, allowing the low-temperature water in the spray channels to carry away this heat, thereby cooling the coolant in the heat exchange channels. Simultaneously, the spray nozzles allow water in the spray channels to flow out through the nozzles, spraying the cutting area of ​​the stone cutting machine to cool and remove chips. This integrates spraying and heat exchange, eliminating the need for refrigeration equipment and reducing the overall space required.

Description

Technical Field

[0001] This invention relates to the field of spray heat exchange technology for stone cutting machines, and particularly to a spray heat exchange device and system for stone cutting machines. Background Technology

[0002] Multi-wire cutting is a common method for cutting semiconductor materials. It uses a high-speed reciprocating diamond wire mesh to cut stone raw materials to the required thickness. During the high-speed reciprocating motion of the diamond wire, the grinding between the diamond wire and the stone raw material generates a large amount of heat and debris. At this time, cutting fluid needs to be sprayed on the cutting area to cool down the area and remove chips. In contrast, multi-wire cutting machines generally use a motor for driving. During the motor driving process, corresponding water-cooling components are also required to cool the motor and ensure its normal operation.

[0003] However, when using the above-mentioned spray cooling and water cooling for the motor, it is generally necessary to use two different cooling systems. Using these two cooling systems will result in the overall space occupied by the multi-wire cutting machine, and the motor cooling system will need to be equipped with refrigeration equipment. Summary of the Invention

[0004] This invention discloses a spray heat exchange device and system for a stone cutting machine, which mainly solves the problem that traditional stone cutting machines generally need to use two different cooling methods to cool the cutting area and the motor separately during operation. This structure eliminates the refrigeration equipment, adopts physical cooling, and reduces the space occupied.

[0005] To achieve the aforementioned objective, the technical solution of the present invention is implemented as follows:

[0006] In a first aspect, the present invention provides a spray heat exchange device for a stone cutting machine, comprising a plurality of spray heat exchange tubes, wherein a plurality of heat exchange baffles are provided in the spray heat exchange tubes to divide the spray heat exchange tubes into a plurality of heat exchange channels and a plurality of spray channels, wherein each of the heat exchange channels is respectively arranged between adjacent spray channels, and a spray nozzle is provided through the spray heat exchange tubes at the position corresponding to the spray channel.

[0007] Each adjacent spray heat exchange tube is connected to the same end by a heat exchange connecting tube, so that the adjacent heat exchange channels are connected to form a continuous S-shaped channel. The two ends of the continuous S-shaped channel are respectively provided with a heat exchange inlet and a heat exchange outlet.

[0008] Both ends of the spray heat exchange tube are connected to spray connecting pipes, so that both ends of the spray channel are connected to the spray connecting pipes, and the spray connecting pipes are provided with spray water inlets.

[0009] In one embodiment, the number of heat exchange channels is one less than the number of spray channels.

[0010] In one embodiment, a drain outlet is provided at one end of the spray connection pipe.

[0011] In one embodiment, the spray nozzle is located on the side of the spray channel away from the heat exchange channel or at the bottom.

[0012] In one embodiment, multiple spray inlets are provided, and the multiple spray inlets are evenly distributed on the spray connecting pipe.

[0013] The advantages or beneficial effects of the above technical solution include at least the following: With the setting of heat exchange channels and spray channels in the spray heat exchange tube of the spray heat exchange device, when the coolant passes through the heat exchange channel, the heat will be conducted to the heat exchange baffle, so that the low temperature water in the spray channel can carry away the heat, thereby achieving the cooling and temperature reduction of the coolant in the heat exchange channel. At the same time, with the setting of the spray nozzle, the water in the spray channel can flow out through the spray nozzle, thereby spraying the cutting part of the stone cutting machine, so as to cool down and remove chips at that location. Thus, spraying and heat exchange can be integrated to reduce the overall space occupied, eliminate the refrigeration equipment, and reduce manufacturing costs.

[0014] Secondly, the present invention provides a spray heat exchange system for a stone cutting machine, comprising the aforementioned spray heat exchange device for a stone cutting machine, a motor unit, a water tank, and a treatment pool. The heat exchange outlet of the spray heat exchange device is connected to the water tank. The water tank is connected to the inlet of the motor unit via a water pump. The outlet of the motor unit is connected to the heat exchange inlet of the spray heat exchange device. The treatment pool is used to receive water sprayed from the spray nozzle of the spray heat exchange device. The treatment pool is connected to the spray inlet of the spray heat exchange device via a water pump.

[0015] In one embodiment, the motor unit includes multiple motors, with the inlet and outlet ends of the multiple motors connected in parallel.

[0016] In one embodiment, the water tank is provided with a water inlet for connecting to an external water supply pipe.

[0017] In one embodiment, the treatment tank is a still water tank or a filtration tank.

[0018] The advantages or beneficial effects of the above technical solution include at least the following: with the cooperation of the heat exchange channel, motor unit and water tank of the spray heat exchange device, the coolant can circulate heat in the heat exchange channel, water tank and motor unit; with the cooperation of the spray channel, spray nozzle and treatment tank of the spray heat exchange device, the spray water can circulate spray in the spray channel and treatment tank, and the coolant in the heat exchange channel is cooled by heat exchange during the spraying process. Thus, the two cooling methods can be combined to reduce the area occupied by the whole system, eliminate the refrigeration equipment and reduce the manufacturing cost. Attached Figure Description

[0043] The names of the messages or information exchanged between the multiple devices in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example 1

[0044] See Figure 1 and Figure 2The present invention provides a spray heat exchange device for a stone cutting machine, including a plurality of spray heat exchange pipes 1, a plurality of heat exchange baffles 11 are provided in the spray heat exchange pipes 1 to divide the spray heat exchange pipes 1 into a plurality of heat exchange channels 12 and a plurality of spray channels 13, each heat exchange channel 12 is respectively arranged between adjacent spray channels 13, and a spray nozzle 14 is provided through the spray heat exchange pipes 1 at the position corresponding to the spray channel 13;

[0045] Each adjacent spray heat exchange pipe 1 is connected to the same end of a heat exchange connecting pipe 2, so that adjacent heat exchange channels 12 are connected to form a continuous S-shaped channel. The two ends of the continuous S-shaped channel are respectively provided with a heat exchange inlet 4 and a heat exchange outlet 5. The heat exchange inlet 4 and the heat exchange outlet 5 are used to connect the equipment to be cooled, so as to perform cooling treatment on the equipment.

[0046] Both ends of the spray heat exchange tube 1 are connected to the spray connecting pipe 3, so that both ends of the spray channel 13 are connected to the spray connecting pipe 3. The spray connecting pipe 3 is provided with a spray water inlet 31.

[0047] With the above structure, through the heat exchange channel 12 and 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 carry away the heat, thereby cooling the coolant in the heat exchange channel 12. At the same time, with the spray nozzle 14, the water in the spray channel 13 can flow out through the spray nozzle 14, thereby spraying the cutting area of ​​the stone cutting machine, so as to cool and remove chips at that location. Thus, spraying and heat exchange can be integrated, reducing the need for coolant cooling equipment, reducing the overall space occupied, eliminating refrigeration equipment, and reducing manufacturing costs.

[0048] In one embodiment, see Figure 2 The number of heat exchange channels 12 is one less than the number of spray channels 13. In practical applications, setting the total number of heat exchange channels 12 to be 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 from the heat exchange channels 12, thereby ensuring the heat exchange efficiency of the heat exchange channels 12.

[0049] In one embodiment, see Figure 1 , Figure 3 and Figure 4 One end of the spray connection pipe 3 is provided with a drain port 32. A valve can be installed at the drain port 32 to control its opening and closing. In practical applications, the drain port 32 facilitates cleaning of the spray connection pipe 3.

[0050] Spray nozzles 14 are located on the side or bottom of the spray channel 13 away from the heat exchange channel 12. Preferably, the spray nozzles 14 of the spray channels 13 located on the left and right sides of the spray heat exchange tube 13 are located on the side of the spray channel 13, with a certain distance between the spray nozzles 14 and the bottom of the spray channel 13. For the spray channels 13 located in the middle of the spray heat exchange tube 13, the spray nozzles 14 are located at the bottom of the spray channel 13. The liquid flow velocity exiting the spray nozzles 14 is lower than the flow velocity in the spray channel 13, giving the liquid in the spray channel 13 a certain hydraulic pressure. This hydraulic pressure forces the liquid out of the spray nozzles 14, ensuring that the sprayed water fills the entire spray channel 13, thus ensuring the heat exchange effect between the spray channel 13 and the heat exchange channel 12. In practical applications, the position of the spray nozzles 14 is restricted to the side or bottom of the spray channel 13 to ensure that the liquid discharged from the spray nozzles 14 can be directly sprayed onto the stone cutting area, thus ensuring the spraying effect.

[0051] In one embodiment, see Figure 1 , Figure 3 and Figure 4 Multiple spray inlets 31 are provided, and these inlets 31 are evenly distributed on the spray connecting pipe 3. Valves can be installed at each spray inlet 31 to control its opening and closing. In practical applications, providing multiple spray inlets 31 on the spray connecting pipe 3 ensures uniform hydraulic pressure flowing into the spray channel 13, guaranteeing sufficient spray water in the spray channel 13 and preventing insufficient spray water due to low pressure in certain areas of the spray channel 13. Example 2

[0052] See Figures 1 to 5The embodiments of the present invention also provide a spray heat exchange system for a stone cutting machine, including the above-mentioned spray heat exchange device for a stone cutting machine, a motor unit 6, a water tank 7, and a treatment pool 8. 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 of the motor unit 6 through a water pump. The water outlet 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 the water sprayed from the spray nozzle 14 of the spray heat exchange device. The treatment pool 8 is connected to the spray inlet 31 of the spray heat exchange device through a water pump. Both the water tank 7 and the treatment pool 8 can be equipped with water pumps, which can transport the coolant in the water tank 7 to the motor unit 6 and into the heat exchange channel 12 of the spray heat exchange device through the heat exchange inlet 4. The water pump in the treatment pool 8 can send the spray water in the treatment pool 8 into the spray channel 13 through the spray inlet 31 to exchange heat with the heat exchange channel 12. At the same time, the spray water in the spray channel 13 is discharged through the spray nozzle 14 to spray and cool down the stone cutting area and reduce dust. During the process of the spray water falling, the heat carried by the spray water will be dissipated into the air, so that the spray water is naturally cooled and then falls into the treatment pool 8.

[0053] With the above structure, the coolant can circulate heat through the heat exchange channel 12, the motor unit 6, and the water tank 7 of the spray heat exchange device. The spray water can circulate spray through the spray channel 13, the spray nozzle 14, and the treatment tank 8 of the spray heat exchange device. During the spraying process, the coolant in the heat exchange channel 12 is cooled by heat exchange. This allows the two cooling methods to be combined, reducing manufacturing costs and minimizing the area occupied by the entire system.

[0054] In one embodiment, see Figure 3 , Figure 4 and Figure 5 The motor unit 6 includes multiple motors 61, with their inlet and outlet water ends connected in parallel. The motors 61 in the motor unit 6 can be water-cooled motors, i.e., motors with water-cooling channels, allowing cooling water to exchange heat with the motors and achieve water cooling. In practical applications, the multiple parallel motors 61 enable the coolant to be pumped from the water tank 7 to the motor unit 6, ensuring effective cooling of the motors 61 by allowing them to pass through simultaneously.

[0055] In one embodiment, see Figure 3 and Figure 4The water tank 7 is equipped with a water inlet 71 for connecting to an external water supply pipe. Similarly, the treatment pool 8 can also be equipped with a corresponding water inlet to replenish the spray water. In practical applications, the water inlet 71 allows for the replenishment of lost coolant from the water tank 7, ensuring effective cooling of the motor unit 6.

[0056] In one embodiment, see Figure 4 and Figure 5 Treatment tank 8 is either a still water tank or a filtration tank. In practical applications, when treatment tank 8 is a still water tank, sedimentation is used to settle the particulate matter formed by the mixture of spray water and dust from the stone cutting process. When treatment tank 8 is a filtration tank, a corresponding filter screen is installed in treatment tank 8 to filter the particulate matter formed by the mixture of spray water and dust from the stone cutting process, thereby ensuring the cleanliness of the spray water delivered by the water pump in treatment tank 8.
