DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Example:

[0023] Reference Figure 1 - Figure 4 The utility model discloses a grinding device for environmentally friendly building materials, including a base 1, a working chamber 2 is provided in the base 1, a motor 3 is embedded in the bottom of the working chamber 2, an output shaft of the motor 3 is rotatably connected to a grinding wheel 4, a humidifying component 5 is provided in the grinding wheel 4, a water circulation mechanism 6 for supplying water to the humidifying component 5 is provided at the bottom of the base 1, and an operating port 7 connected to the working chamber 2 is provided at the top of the base 1.

[0024] In this embodiment, when it is necessary to grind the environmentally friendly building materials, the motor 3 is started, and the grinding wheel 4 is driven by the motor 3 to rotate at high speed, and then the environmentally friendly building materials are placed at the working opening 7. When the environmentally friendly building materials come into contact with the grinding wheel 4, the surface of the environmentally friendly building materials is polished by the rough surface of the grinding wheel 4.

[0025] During the process of grinding the environmentally friendly building materials by the grinding wheel 4, the grinding wheel 4 will simultaneously throw out cooling water through the humidifying component 5, which can soak the surface of the environmentally friendly building materials, so that the waste materials of the environmentally friendly building materials that are ground off will not fly around but drip into the working chamber 2 with the water flow, which can effectively reduce the subsequent cleaning difficulty and reduce the impact on the health of workers during the surface treatment of environmentally friendly building materials.

[0026] The dripping water will gather at the bottom of the working chamber 2, and then the impurity particles mixed in the sewage will be filtered through the water circulation mechanism 6 and then re-delivered to the grinding wheel 4 for water recycling, which can effectively reduce water waste and reduce the use cost of the grinding device.

[0027] In a further preferred embodiment of the present invention, Figure 3 and Figure 4As shown, the humidifying component 5 includes a ball 51 and a support spring 52. A plurality of humidifying grooves 8 are provided in a circular array on the outer wall of the grinding wheel 4. A water storage chamber 9 is provided inside the grinding wheel 4. The humidifying groove 8 is connected to the water storage chamber 9 through a drainage hole 10. A water retaining groove 11 is formed in the middle of the inner wall of the drainage hole 10. A ball 51 is provided in the water retaining groove 11. A support spring 52 is provided between the side of the ball 51 away from the water storage chamber 9 and the water retaining groove 11.

[0028] In this embodiment, by providing a water storage chamber 9 inside the grinding wheel 4 and a humidifying tank 8 outside, and the humidifying tank 8 and the water storage chamber 9 are connected through the drainage hole 10, the grinding wheel 4 can throw out water when rotating at a high speed, which can effectively reduce the dust generated during the grinding process, and the thrown out water can also take away the temperature of the surface of the grinding wheel 4 and the building environmental protection material, thereby avoiding overheating and damage of the grinding wheel 4 or the building environmental protection material, and improving the processing efficiency of the building environmental protection material.

[0029] Because the drainage hole 10 is provided, when the grinding wheel 4 stops running, the liquid in the water storage chamber 9 will also flow out continuously. The outflowing water will be evaporated by the air when in contact with the air, resulting in water loss. Therefore, in order to reduce water waste, a water retaining groove 11 is provided in the drainage hole 10, and a ball 51 for blocking the drainage hole 10 is provided in the water retaining groove 11, and a supporting spring 52 is provided on the side of the ball 51 away from the water storage chamber 9, so that the grinding wheel 4 can block the drainage hole 10 when it stops, thereby reducing water waste. When the grinding wheel 4 rotates at high speed, the ball 51 is separated from the drainage hole 10 due to the swinging of centrifugal force, so that water can be discharged normally through the drainage hole 10, thereby further reducing water waste while ensuring that water can be sprayed normally.

[0030] In a further preferred embodiment of the present invention, Figure 4 As shown, the diameter of the ball 51 is smaller than the diameter of the water retaining groove 11 and larger than the diameter of the drainage hole 10 .

[0031] In this embodiment, because the ball 51 needs to block the drain hole 10, the diameter of the ball 51 needs to be larger than the diameter of the drain hole 10. When the ball 51 is separated from the drain hole 10, water needs to be discharged through the drain hole 10 and the water retaining groove 11. Therefore, a gap needs to be left between the ball 51 and the water retaining groove 11 for water to pass through, so the diameter of the ball 51 is made smaller than the diameter of the water retaining groove 11.

[0032] In a further preferred embodiment of the present invention, Figure 2 and Figure 3As shown, the water circulation mechanism 6 is composed of a water tank 61, a water receiving trough 62, a filter element 63, a water supply pipe 64, a return pipe 65 and a sealing ring 66, wherein the water tank 61 is arranged in the base 1, and the top of the water tank 61 is connected to the sealing ring 66 through the water supply pipe 64, the bottom of the grinding wheel 4 is provided with a circular groove 12 connected to the water storage chamber 9, and is rotatably connected to the sealing ring 66, the inner bottom wall of the working chamber 2 is provided with a water receiving trough 62, the bottom of the water receiving trough 62 is connected to the water tank 61 through the return pipe 65, and the middle of the return pipe 65 is provided with a filter element 63.

[0033] In this embodiment, because the grinding wheel 4 needs to rotate at high speed to process the surface of the building environmental protection material, and the fixed connection between the water supply pipe 64 and the grinding wheel 4 will cause the water supply pipe 64 to be entangled on the output shaft of the motor 3 and broken when the grinding wheel 4 rotates, an annular groove 12 is opened at the bottom of the grinding wheel 4, and a sealing ring 66 is rotatably connected in the annular groove 12. The water supply pipe 64 is then connected to the sealing ring 66, so that the grinding wheel 4 can rotate normally while the water supply pipe 64 can maintain water supply normally.

[0034] Then, when the grinding wheel 4 sprays water onto the surface of the environmentally friendly building material, the water will mix with the crushed materials of the environmentally friendly building material and then drip into the working chamber 2. Therefore, in order to prevent the sewage from overflowing the working chamber 2 and increasing the difficulty of cleaning, a water receiving tank 62 is provided at the bottom of the working chamber 2 for the reflux of the sewage. After the sewage enters the water receiving tank 62, it will flow back into the water tank 61 through the reflux pipe 65. When the sewage passes through the reflux pipe 65, it will be intercepted by the filter element 63 to filter out the particulate impurities carried in the sewage to avoid clogging of the drainage hole 10 of the grinding wheel 4.

[0035] In a further preferred embodiment of the present invention, Figure 3 As shown, the bottom of the water supply pipe 64 extends into the water tank 61 and contacts the inner bottom wall of the water tank 61 , and the bottom of the return pipe 65 extends into the water tank 61 and is close to the inner top wall of the water tank 61 .

[0036] In this embodiment, by locating the bottom of the water supply pipe 64 at the bottom of the water tank 61, the water supply pipe 64 can pump the water in the water tank 61 under the action of the water pump to supply the grinding wheel 4, and the bottom of the return pipe 65 is set at the top of the water tank 61, so that the water returned by the return pipe 65 can drip directly into the water tank 61, avoiding that when the bottom of the return pipe 65 is flush with the bottom of the water supply pipe 64, the return pipe 65 accelerates the flow of water in the pipe due to the suction force generated by the bottom of the water supply pipe 64, thereby affecting the filtering effect of sewage.

[0037] Among them, the above-mentioned water pump is a commercially available product and is not within the scope of improvement of this application, so it will not be described in detail.

[0038] In a further preferred embodiment of the present invention, Figure 2 As shown, a fillet 13 is processed at the intersection of the opening of the humidifying tank 8 and the outer edge of the grinding wheel 4 .

[0039] In this embodiment, because a plurality of humidifying grooves 8 are provided at the outer edge of the grinding wheel 4, when the grinding wheel 4 rotates at a high speed, the notches of the humidifying grooves 8 will hit the environmentally friendly building materials. Therefore, in order to reduce the damage caused to the environmentally friendly building materials by the opening edges of the humidifying grooves 8, rounded corners 13 are processed at the edges of the humidifying grooves 8, which can effectively reduce the damage to the environmentally friendly building materials.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
