Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically a wet grinding machine. Background Technology

[0002] A wet grinding wheel machine is a grinding equipment that uses water as a cooling medium. It mainly consists of a grinding wheel, a protective cover, a water tank, and a motor. During operation, the grinding wheel rotates at high speed to perform grinding operations, while the water in the water tank continuously cools the contact area between the grinding wheel and the workpiece. This effectively prevents the workpiece from annealing or deforming due to the high temperature generated during grinding, or the grinding wheel from overheating and being damaged. It also reduces dust and improves the working environment. It is widely used in metal processing, machinery manufacturing, and other fields, and is especially suitable for grinding scenarios with high precision and workpiece performance requirements, such as sharpening cutting tools and finishing the surface of parts.

[0003] During the use of current wet grinding machines, water droplets are easily splashed out at the contact point between the workpiece and the grinding wheel due to centrifugal force and grinding impact. At the same time, the high temperature of grinding also generates a certain amount of water mist, which can easily obstruct the operator's vision. The splashed water droplets also have an impact on the environment. Therefore, we propose a wet grinding machine. Utility Model Content

[0004] The purpose of this utility model is to provide a wet grinding machine that can prevent water droplets from splashing and scattering during the operation of the wet grinding machine, thereby avoiding the impact on the surrounding environment. At the same time, it can also prevent the water mist generated from obstructing the operator's vision and is conducive to saving water resources. It solves the problems of current wet grinding machines, where water droplets are easily splashed out at the contact point between the workpiece and the grinding wheel due to centrifugal force and grinding impact, and the high temperature of grinding also generates a certain amount of water mist, which can easily obstruct the operator's vision and cause water droplets to splash and scatter, thus impacting the environment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wet grinding machine, comprising a base, a water tank, a high-pressure blower, and a support seat fixedly mounted on the upper surface of the base, a rotating motor and a protective cover fixedly mounted on the upper surface of the support seat, a grinding wheel fixedly mounted at the end of the output shaft of the rotating motor, and the grinding wheel being located inside the protective cover, an opening provided on the front surface of the protective cover, a one-way valve fixedly connected to the lower surface of the protective cover, a drain pipe fixedly connected to the end of the one-way valve, an air duct fixedly connected to the output end of the high-pressure blower, and the end of the air duct fixedly connected to the outer surface of the drain pipe, a water pump fixedly mounted on the rear surface of the water tank, a water spray pipe fixedly connected to the output end of the water pump, and the end of the water spray pipe being located above the opening.

[0006] Preferably, the protective cover is located above the water tank, and the end of the drain pipe is located inside the water tank.

[0007] Preferably, a demister is fixedly installed inside the water tank near the upper surface, and a drain pipe passes through the demister.

[0008] Preferably, the included angle α between the axes of the air duct and the drain pipe is ≤45°.

[0009] Preferably, a fixing block is fixedly installed on the upper surface of the protective cover, and the water spray pipe passes through the fixing block.

[0010] Preferably, a universal joint is fixedly connected to the end of the water spray pipe, and a nozzle is fixedly connected to the end of the universal joint.

[0011] Preferably, a filter is fixedly connected to the input end of the water pump, and the end of the filter is fixedly connected to the rear surface of the water tank near the lower surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a base, support seat, water tank, high-pressure blower, grinding wheel, water pump, spray pipe, drain pipe, and one-way valve, achieves the effect of avoiding water droplets splashing and scattering during the operation of a wet grinding machine, thus avoiding impact on the surrounding environment. It also prevents water mist from obstructing the operator's view and helps conserve water resources. The rotating motor drives the grinding wheel to rotate, performing grinding and other processing on the workpiece. The water pump operates, causing water from the water tank to be sprayed onto the grinding wheel and workpiece through the spray pipe, achieving the purpose of cooling the workpiece and grinding wheel, and also serving a dust removal function. Wastewater is discharged into the water tank through the one-way valve and drain pipe. Simultaneously, the high-pressure blower operates, allowing high-pressure air to enter the drain pipe. As the high-pressure air flows downwards inside the drain pipe, it creates a siphon effect at the opening of the protective cover, drawing splashed water droplets and water mist into the protective cover along with the air, and finally draining into the water tank through the drain pipe.

[0014] 2. This utility model achieves the effect of saving water resources by setting up a demister. As the moisture rises and is discharged from the inside of the water tank, it comes into contact with the demister and condenses into droplets on the demister, and then drips into the inside of the water tank.

[0015] 3. By setting a universal joint tube, this utility model facilitates the adjustment of the nozzle position, thereby making it easy to adjust the water sprayed onto the grinding wheel and workpiece according to usage requirements. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figures 1-4 As shown, this utility model proposes a wet grinding machine, including a base 1. A water tank 3, a high-pressure blower 4, and a support 8 are fixedly installed on the upper surface of the base 1. A rotating motor 7 and a protective cover 6 are fixedly installed on the upper surface of the support 8. The protective cover 6 is located above the water tank 3. A grinding wheel 16 is fixedly installed at the end of the output shaft of the rotating motor 7, and the grinding wheel 16 is located inside the protective cover 6. An opening 11 is provided on the front surface of the protective cover 6. The workpiece is in contact with the grinding wheel 16 at the opening 11, and the workpiece is ground or processed by the grinding wheel 16. A one-way valve 10 is fixedly connected to the lower surface of the protective cover 6. A drain pipe 9 is fixedly connected to the end of the one-way valve 10, and the end of the drain pipe 9 is located inside the water tank 3. The end of the drain pipe 9 is located above the water surface inside the water tank 3. The output end of the high-pressure blower 4 is fixedly connected to the air duct 5, and the end of the air duct 5 is fixedly connected to the outer surface of the drain pipe 9. The included angle α between the axes of the air duct 5 and the drain pipe 9 is ≤45°, which is conducive to the downward flow of high-pressure air along the drain pipe 9. The rear surface of the water tank 3 is fixedly installed with a water pump 17. The output end of the water pump 17 is fixedly connected to a spray pipe 15, and the end of the spray pipe 15 is located above the opening 11. The upper surface of the protective cover 6 is fixedly installed with a fixing block 14, and the spray pipe 15 passes through the fixing block 14. The input end of the water pump 17 is fixedly connected to a filter 18, and the end of the filter 18 is fixedly connected to the rear surface of the water tank 3 near the lower surface.

[0024] In use, the rotating motor 7 drives the grinding wheel 16 to rotate, and the grinding wheel 16 performs grinding and other processing on the workpiece. The water pump 17 works, causing water in the water tank 3 to be sprayed onto the grinding wheel 16 and the workpiece through the water spray pipe 15, so as to cool the workpiece and the grinding wheel 16 and also to remove dust. Wastewater is discharged into the water tank 3 through the one-way valve 10 and the drain pipe 9. At the same time, the high-pressure fan 4 works, so that high-pressure air enters into the drain pipe 9. As the high-pressure air flows downward in the drain pipe 9, it creates a siphon effect at the opening 11 of the protective cover 6, so that the splashed water droplets and water mist are sucked into the protective cover 6 along with the air and finally discharged into the water tank 3 through the drain pipe 9. This can prevent water droplets from splashing and scattering during the operation of the wet grinding machine, thereby avoiding the impact on the surrounding environment. It can also prevent the water mist from obstructing the operator's vision and is also conducive to saving water resources.

[0025] Example 2

[0026] like Figures 1-4 As shown, the wet grinding machine proposed in this utility model, compared with the first embodiment, further includes a demister 2 fixedly installed inside the water tank 3 near the upper surface, and a drain pipe 9 passing through the demister 2. The demister 2 is an existing gas-liquid separation device mainly composed of corrugated blades, plates, clamping strips and other fixing devices. A universal joint pipe 13 is fixedly connected to the end of the water spray pipe 15, and a nozzle 12 is fixedly connected to the end of the universal joint pipe 13. The position of the nozzle 12 can be adjusted by the universal joint pipe 13, so as to facilitate the adjustment of the water sprayed onto the grinding wheel 16 and the workpiece according to the usage requirements.

[0027] In this embodiment, as the moisture rises and is discharged from the inside of the water tank 3, it comes into contact with the demister 2 and condenses into droplets on the demister 2, and then drips into the inside of the water tank 3.
