DETAILED DESCRIPTION
[0019] Please refer to Figs. 1-2 A sludge removal system of grinding equipment, comprising grinding equipment 10, collecting tank 20, first water pump 30, solid-liquid separation equipment 40 and second water pump 50.
[0020] The grinding equipment 10 is used for grinding products with grinding liquid, and is provided with grinding liquid inlet 11 and grinding liquid outlet 12, the grinding liquid inlet 11 is used for introducing new grinding liquid into the grinding equipment 10, and the grinding liquid outlet 12 is used for discharging used waste grinding liquid.
[0021] The inlet of the collecting tank 20 is communicated with the grinding liquid outlet 12 of the grinding equipment 10, and is used for collecting the waste grinding liquid discharged therefrom. As a preferred, the collecting tank 20 is provided with a filtering screen 21 at the top, which is used for preliminarily filtering the waste grinding liquid to filter out the larger grinding sludge therein, so as to avoid damaging the subsequent pipeline and equipment.
[0022] The first water pump 30 is communicated with the collecting tank 20 at one end and with the solid-liquid separation equipment 40 at the other end, and is used for conveying the waste grinding liquid in the collecting tank 20 to the solid-liquid separation equipment 40.
[0023] The solid-liquid separation device 40 comprises a shell 41, a liquid pump 42, a rotating drum 43 and a motor 44. The shell 41 is provided with a liquid inlet 411 and a liquid outlet 412, the liquid inlet 411 is communicated with the output end of the first water pump 30 for inputting the waste grinding liquid, and the liquid outlet 412 is used for outputting the filtered pure grinding liquid. The liquid pump 42 is arranged inside the shell 41, the input end of the liquid pump 42 is connected with the liquid inlet 411 of the shell 41, and the output end of the liquid pump 42 extends into the rotating drum 43 for pumping the waste grinding liquid into the rotating drum 43. The rotating drum 43 is rotatably installed in the shell 41, and the bottom surface of the rotating drum 43 is provided with an opening, and the output end of the liquid pump 42 extends into the rotating drum 43 from the bottom surface opening. The motor 44 is drivingly connected with the rotating drum 43 for driving the rotating drum 43 to rotate at high speed. The high-speed rotation of the rotating drum 43 makes the waste grinding liquid in the rotating drum 43 do the centrifugal motion, and because the centrifugal effects on the solid waste residues and the grinding liquid in the waste grinding liquid are different, the solid waste residues will be attached to the inner wall of the rotating drum under the centrifugal effect, so that the solid waste residues and the grinding liquid are separated. After the rotating drum stops rotating, the pure grinding liquid flows out of the rotating drum from the bottom opening of the rotating drum under the action of gravity and is discharged through the liquid outlet of the shell.
[0024] Preferably, the bottom of the shell 41 is provided with a residue discharge port 413, and the position of the residue discharge port 413 is opposite to the position of the bottom opening of the rotating drum 43, for discharging the separated solid waste residues. Correspondingly, the solid-liquid separation device 40 further comprises a residue discharge gate 45, which is rotatably installed on the inside bottom of the shell 41 through a connecting piece, and the shape and size of the residue discharge gate 45 are equivalent to those of the residue discharge port 413, so that the residue discharge gate 45 can completely cover the residue discharge port 413 when it is closed. During the separation process and after the separation is completed, the residue discharge gate 45 is closed to prevent the grinding liquid from flowing out of the residue discharge port 413; when it is necessary to clean the solid waste residues, the residue discharge gate 45 is opened to discharge the solid waste residues from the residue discharge port 413. Preferably, the residue discharge gate 45 is in the shape of a conical body, and the center of the residue discharge gate 45 is protruded to form a certain inclination angle, which is beneficial to guide the flow direction of the grinding liquid when the grinding liquid flows out of the residue discharge gate 45, so as to avoid the accumulation of the grinding liquid on the residue discharge gate 45.
[0025] As a preferred, the upper part of the rotating drum 43 is a hollow cylinder, the lower part gradually reduces in radius to form an inverted hollow circular table, the bottom has the smallest radius and is equivalent to the radius of the residue discharge port 413, so that the lower part forms a certain inclination slope, which is beneficial to guide the direction of discharging the solid waste residues and avoid splashing onto the bottom of the shell 41 to pollute the subsequent pure grinding liquid.
[0026] More preferably, the solid-liquid separation device 40 further comprises a scraper 46. The scraper 46 is movably installed inside the rotating drum 43, the length of the scraper 46 is equivalent to the height of the rotating drum 43, the width is about one fourth of the inner diameter of the rotating drum 43, and the side close to the inner wall of the rotating drum 43 matches the shape of the inner wall of the rotating drum 43. When the rotating drum 43 rotates to perform centrifugal action, the scraper 46 moves to the center of the rotating drum 43, away from the inner wall of the rotating drum 43 to avoid contact with the solid waste attached to the inner wall. When the rotating drum 43 needs to clean the solid waste, the scraper 46 moves to the inner wall of the rotating drum 43 so that the outer side of the scraper 46 closely adheres to the inner wall of the rotating drum 43. At this time, the rotating drum 43 rotates or the scraper 46 rotates along the inner wall of the rotating drum 43 to scrape off the solid waste attached to the inner wall of the rotating drum 43, thereby achieving automatic cleaning of the waste.
[0027] The second water pump 50 is connected to the liquid outlet 412 of the solid-liquid separation device 40 at one end and connected to the grinding liquid inlet 11 of the grinding device 10 at the other end, for conveying the pure grinding liquid filtered by the solid-liquid separation device 40 to the grinding device 10 for recycling. By setting the solid-liquid separation device 40 to filter the waste grinding liquid, pure grinding liquid without waste residue impurities is obtained, and the pure grinding liquid is conveyed back to the grinding device 10 for repeated use, which can greatly reduce the consumption of grinding liquid and reduce production costs. At the same time, the filtered pure grinding liquid has the same performance as the new grinding liquid, effectively improving the consistency of product production.
[0028] In some embodiments, the grinding device residue removal system further comprises a second collection tank 60, a peristaltic pump 61, and a third water pump 70. The second collection tank 60 is arranged between the collection tank 20 and the solid-liquid separation device 40 for temporary storage. One end of the second collection tank 60 is connected to the first water pump 30, and the other end is connected to the solid-liquid separation device 40 through the third water pump 70. The peristaltic pump 61 is arranged in the second collection tank 60 for circulating the waste grinding liquid in the second collection tank 60 to avoid the solid waste in the waste grinding liquid from settling on the bottom and causing blockage of the pipeline during pumping. The waste grinding liquid discharged from the grinding device 10 is first discharged into the collection tank 20, and then conveyed to the second collection tank 60 by the first water pump 30. The waste grinding liquid circulates under the action of the peristaltic pump 61, so that the waste is uniformly mixed in the grinding liquid. When the solid-liquid separation device 40 needs it, the waste grinding liquid is conveyed to the solid-liquid separation device 40 by the third water pump 70 for filtration and separation. As a preferred embodiment, the third water pump 70 is a pneumatic diaphragm pump, which has more stable conveying effect for waste grinding liquid containing waste residue particles, can provide stable flow of waste grinding liquid input to the solid-liquid separation device 40, and ensure the working efficiency of the solid-liquid separation device 40.
[0029] In some embodiments, the slag removal system of the grinding device further comprises a cooling tank 81 and a cooling machine 82 for reducing the temperature of the pure grinding liquid discharged from the solid-liquid separation device 40. The inlet of the cooling tank 81 is connected with the liquid outlet 412 of the solid-liquid separation device 40, and the outlet of the cooling tank 81 is connected with the second water pump 50 for containing the pure grinding liquid obtained by filtration. The cooling machine 82 is installed on the top of the cooling tank 81 and is provided with heat dissipation copper pipes extending into the cooling tank 81. The cooling machine 82 is filled with coolant which circulates in the heat dissipation copper pipes, and the coolant contacts with the pure grinding liquid in the cooling tank 81 and takes away the heat of the pure grinding liquid, so as to reduce the temperature of the pure grinding liquid.
[0030] In some embodiments, the slag removal system of the grinding device further comprises a flow meter 90 installed on the pipeline of the grinding liquid inlet 11 of the grinding device 10 for detecting the flow of the delivered pure grinding liquid. When the pipeline is blocked, the flow meter will issue an alarm when detecting a decrease in flow, thereby reminding the staff to clean the blockage in time to prevent the grinding device from being dry ground without grinding liquid.
[0031] In use, the grinding liquid is added to the grinding device 10 for grinding, and the waste grinding liquid after grinding is discharged from the grinding liquid outlet 11 to the collection tank 20 and is preliminarily filtered through the filter screen 21 on the top of the collection tank 20, and then is delivered to the second collection tank 60 by the first water pump 30 for temporary storage. When the solid-liquid separation device 40 needs, the third water pump 70 delivers the waste grinding liquid in the second collection tank 60 to the solid-liquid separation device 40 for separation, and the obtained pure grinding liquid is delivered to the cooling tank 81 for cooling and temperature reduction, and finally is delivered back to the grinding device 10 for recycling.
[0032] The slag removal system of the grinding device disclosed in the utility model separates the waste grinding liquid discharged from the grinding device by the solid-liquid separation device to obtain the pure grinding liquid which can be recycled. Compared with the prior art, the grinding liquid for recycling is filtered and separated in real time in the utility model, the recycling of the grinding liquid is realized, the production resource utilization rate is effectively improved, and the production cost is reduced.
