Description

Technical Field

[0001] This application relates to the field of coolant reuse technology, and in particular to a coolant reuse device for a drilling machine. Background Technology

[0002] During the machining process of a drilling machine, coolant is usually sprayed from the nozzle next to the drilling machine spindle and acts directly on the machining area of ​​the drill bit and the workpiece. It cools down by absorbing heat and lubricating, thus preventing the workpiece from deforming due to high temperature and the drill bit from wearing out. After use, the coolant is collected in the guide groove under the drilling machine table and flows into the collection tank below for initial recycling.

[0003] After the coolant cools the drill bit and workpiece on the drilling machine, it flows directly from the guide channel into the collection tank. Because the coolant contains impurities left during the workpiece processing, the coolant cannot be used directly after flowing into the collection tank, resulting in waste of coolant.

[0004] Therefore, those skilled in the art have provided a device for the secondary utilization of coolant in drilling machines to solve the problems mentioned in the background art. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a device for secondary utilization of coolant in drilling machines.

[0006] The coolant recycling device for a drilling machine provided in this application adopts the following technical solution:

[0007] A device for secondary utilization of coolant in a drilling machine includes a collection tank with an open top. An inclined filter screen is slidably inserted into the upper part of the collection tank. One end of the filter screen is fixed with a side plate inserted into the inner wall of the collection tank. A water pump is fixed to the left side of the bottom of the collection tank. An inlet pipe extending into the collection tank is fixed to the inlet of the water pump. A drain pipe is fixed to the outlet of the water pump. A housing is fixed to one end of the drain pipe. A return pipe is fixed to the upper part of the housing. A horizontally arranged outlet pipe is fixed to the return pipe. A main pipe is fixed to the outlet pipe. An inclined flushing pipe is fixed to the main pipe. One end of the flushing pipe extends into the inner wall of the upper part of the collection tank.

[0008] In this invention, the angle between the right end of the filter screen and the side plate is 70-85 degrees, which allows the filter screen to be tilted, thus facilitating the flushing of impurities on the filter screen to the right side.

[0009] Preferably, the housing is rotatably connected to a rotating shaft, the rotating shaft is rotatably connected to the inner wall of the liquid collection tank, a stirring blade is fixed to the outer wall of the rotating shaft, and a turbine located inside the housing is fixed to one end of the rotating shaft.

[0010] In this invention, when the coolant is pumped into the tank, it flows and impacts the turbine, which drives the rotating shaft and the agitator to rotate. The agitator stirs the filtered coolant in the collection tank, promoting heat exchange between the coolant and the outside air, thus further dissipating heat and ensuring that the coolant can effectively cool the workpiece processed by the drilling machine when it is reused.

[0011] Preferably, the number of flushing pipes is at least eight, and the bottom opening of the flushing pipes faces the upper end of the filter screen.

[0012] Preferably, a heat dissipation vent is provided through the right side of the liquid collection tank, and a heat dissipation mesh is fixed inside the heat dissipation vent of the liquid collection tank.

[0013] Preferably, the liquid collection tank has a slot at its upper end, the side plate is vertically slidably inserted into the slot, the liquid collection tank is threadedly connected with bolts for pressing the side plate, the liquid collection tank has a notch at its upper end, and the side plate is inserted into the notch.

[0014] Preferably, the drain pipe is spirally surrounding the outer casing of the water pump, and three vertically arranged heat sinks are fixed to the outer wall of the return pipe.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. This application can filter the coolant discharged from the drilling machine, and after filtration, it can be pumped back to the drilling machine cooling tank for reuse. At the same time, during the return process, impurities on the filter screen can be collected, reducing coolant waste and ensuring the cleanliness of the coolant for reuse.

[0017] 2. When the coolant is pumped into the return pipe, some coolant will flow from the outlet pipe and the main pipe into the flushing pipe, flushing the upper part of the filter screen and flushing the impurities to the right side of the filter screen for storage, thus avoiding excessive blockage on the surface of the filter screen and ensuring the continuous and stable operation of the filtration system.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figure 1-3 As shown, this application discloses a coolant secondary utilization device for a drilling machine, including a collection tank 1 with an open top. An inclined filter screen 11 is slidably inserted into the upper end of the collection tank 1. One end of the filter screen 11 is fixed with a side plate 13 inserted into the inner wall of the collection tank 1. A water pump 8 is fixed to the left side of the bottom end of the collection tank 1. An inlet pipe 9 extending into the inside of the collection tank 1 is fixed to the inlet of the water pump 8. A drain pipe 7 is fixed to the outlet of the water pump 8. A housing 6 is fixed to one end of the drain pipe 7. A return pipe 5 is fixed to the upper end of the housing 6. A horizontally arranged outlet pipe 3 is fixed to the return pipe 5. A main pipe 2 is fixed to the outlet pipe 3. An inclined flushing pipe 10 is fixed to the main pipe 2. One end of the flushing pipe 10 extends into the inner wall of the upper end of the collection tank 1. The top end of the return pipe 5 is connected to the coolant tank on the drilling machine via a flexible hose. The collection tank 1 is installed on the drilling machine, and the upper end of the collection tank 1 is used to collect the coolant flowing from the drilling machine's guide channel. The coolant is filtered through filter screen 11 at the top of the collection tank 1. The filtered coolant falls into the collection tank 1 for storage. By starting the water pump 8, the filtered coolant in the collection tank 1 is drawn in through the inlet pipe 9, then sent to the tank body 6 through the drain pipe 7, then to the return pipe 5, and finally to the cooling tank of the drilling machine (not shown in the figure) for secondary use by the drilling machine. When the coolant is sent to the return pipe 5 by the water pump 8, part of the coolant flows from the outlet pipe 3 into the main pipe 2, and then flows out from the flushing pipe 10 and rushes to the top of the filter screen 11, flushing the impurities on the top of the filter screen 11 to the right side of the filter screen 11 for storage. Then the coolant flushed out from the flushing pipe 10 passes through the filter screen 11 and re-enters the collection tank 1. This can prevent too much blockage on the upper surface of the filter screen 11 and concentrate the collection of impurities, which is conducive to the recovery and filtration of coolant on the drilling machine, and then sent to the cooling tank for secondary use by the water pump 8.

[0025] To agitate the coolant that has entered the collection tank 1 for filtration, a rotating shaft 4 is rotatably connected to the tank body 6. The rotating shaft 4 is rotatably connected to the inner wall of the collection tank 1, and a stirring blade 15 is fixed to the outer wall of the rotating shaft 4. A turbine 14 located inside the tank body 6 is fixed to one end of the rotating shaft 4. When the coolant recovered from the drilling machine enters the collection tank 1 through the filter screen 11 and is pumped into the tank body 6 through the drain pipe 7 by the water pump 8, the coolant flows inside the tank body 6, impacting the turbine 14 and causing it to rotate. This causes the rotating shaft 4 to rotate, making the three stirring blades 15 rotate inside the collection tank 1, agitating the internally filtered coolant. This facilitates the exchange of heat between the coolant inside the collection tank 1 and the outside air, further dissipating heat from the coolant. It also facilitates the recycling and reuse of the coolant for cooling the workpiece during drilling.

[0026] In order to facilitate the flushing of impurities on the filter screen 11 to the left end of the filter screen 11, the number of flushing pipes 10 is at least eight, and the bottom opening of the flushing pipes 10 faces the top of the filter screen 11.

[0027] A heat dissipation vent 17 is provided through the right side of the liquid collection tank 1, and a heat dissipation mesh 18 is fixed inside the heat dissipation vent 17 in the liquid collection tank 1; the turbine 14 rotates under the impact of coolant, which drives the agitator 15 on the rotating shaft 4 to rotate and agitate the coolant inside the liquid collection tank 1. The setting of the heat dissipation mesh 18 is conducive to air circulation, so that the coolant agitated in the liquid collection tank 1 can quickly exchange heat with the outside air from the heat dissipation vent 17 to cool down.

[0028] The upper end of the liquid collection tank 1 has a slot 19, and the side plate 13 is vertically slidably inserted into the slot 19. The liquid collection tank 1 is threadedly connected with a bolt 12 for pressing the side plate 13. The upper end of the liquid collection tank 1 has a notch 16, and the side plate 13 is inserted into the notch 16. By rotating the disassembly bolt 12, the side plate 13 can be moved upward to disengage from the slot 19 and the notch 16, which will drive the filter screen 11 upward to disengage from the liquid collection tank 1, making it easier to clean the impurities on the filter screen 11 and facilitate the filter screen 11 to filter the coolant recovered from the drilling machine again.

[0029] Example 2

[0030] In this embodiment, the drain pipe 7 is spirally wrapped around the outer casing of the water pump 8, and three vertically arranged heat sinks 20 are fixed on the outer wall of the return pipe 5. By setting the drain pipe 7 in a spiral shape around the water pump 8, when the water pump 8 is working, the coolant in the collection tank 1 is drawn in from the inlet pipe 9 and then sent into the drain pipe 7. The coolant is then sent into the tank 6 and the return pipe 5. During the flow of the coolant in the spiral drain pipe 7, some heat around the water pump 8 is carried away, which cools the water pump 8. The coolant that has absorbed heat then enters the return pipe 5 and exchanges heat with the outside through the heat sinks 20 to cool down. Finally, the cooled coolant flows from the return pipe 5 and the hose into the cooling tank for secondary use.

[0031] It should be noted that after the coolant enters the spiral drain pipe 7 and absorbs the heat from the water pump 8, it flows into the return pipe 5 and is cooled by the heat sink 20. The coolant that flows back into the cooling box does not affect the cooling effect on the workpiece.

[0032] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: The upper end of the collection tank 1 is used to receive the coolant flowing out of the drill press guide groove. The coolant flows to the upper end of the collection tank 1 and is filtered by the filter screen 11. The filtered coolant falls into the collection tank 1 for storage. By starting the water pump 8, the filtered coolant in the collection tank 1 is pumped in through the inlet pipe 9, then sent to the tank body 6 through the drain pipe 7, then sent to the return pipe 5, and finally sent to the cooling box on the drill press for secondary use. When the coolant is sent to the return pipe 5 by the water pump 8, part of the coolant flows from the outlet pipe 3 into the main pipe 2, and then flows out from the flushing pipe 10 and rushes to the upper end of the filter screen 11, flushing the impurities on the upper end of the filter screen 11 to the right side of the filter screen 11 for storage. Then the coolant flushed out from the flushing pipe 10 passes through the filter screen 11 and re-enters the collection tank 1. This can prevent too much blockage on the upper surface of the filter screen 11 and collect impurities, which is conducive to the recovery and filtration of coolant on the drill press, and then sent to the cooling box for secondary use by the water pump 8.
