[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0044] Please also refer to Figures 1 to 12 , a basic magnesium carbonate washing equipment provided by the present application is now described. The basic magnesium carbonate washing equipment comprises a washing tank 1 and a driving part 2; the washing tank 1 has a feeding port 11 and a water feeding port 12 on the top, and a drain port 13 on the bottom; the drain port 13 is connected to the vacuum filtration equipment through a pipe; a filter cloth filtering structure 3 is provided inside the washing tank 1, and a discharge port is provided on the side wall of the washing tank 1 at the top of the filter cloth filtering structure 3. The discharge port, the feeding port 11 and the drain port 13 are all provided with valves, which may be solenoid valves. The vacuum filtration equipment may be a vacuum pump, which is a prior art and will not be described in detail here. The vacuum pump pumps the wastewater into a designated wastewater pool. The discharge port is connected to a pipe, and the valve is arranged on the pipe.

[0045] The driving member 2 is arranged at the top of the washing tank 1; the output shaft of the driving member 2 is connected to the spline shaft 4; the spline shaft 4 is connected to the spline cylinder 5, and the bottom end of the spline cylinder 5 is connected to the stirring blade 6; wherein, the output end of the driving member 2 is connected to the supporting component 8 through the connecting member 7, and the top of the supporting component 8 has a displacement component 9, and the displacement component 9 is connected to the spline cylinder 5; the spline shaft 4 can be welded to the output shaft of the driving member.

[0046] The supporting component 8 and the end opposite to the displacement component 9 both have an inclined surface. When the displacement component 9 rotates following the spline cylinder 5 and the stirring blade 6 , the stirring blade 6 can reciprocate in the axial direction.

[0047] The present application provides a basic magnesium carbonate washing equipment. Compared with the prior art, when cleaning the basic magnesium carbonate, the material is introduced into the washing tank 1 through the feeding port 11, and then water is introduced into the washing tank 1 through the water feeding port 12; the driving member 2 can drive the stirring blade 6 to rotate through the spline shaft 4 and the spline cylinder 5. During the rotation of the stirring blade 6, the displacement component 9 is relatively fixed to the stirring blade 6, and the support component 8 provides support for the displacement component 9, and the end opposite to the support component 8 and the displacement component 9 has an inclined surface; therefore, during the rotation of the displacement component 9, it can move up and down along the axial direction, thereby driving the stirring blade 6 to move up and down; through the above-mentioned arrangement, in the process of stirring the basic magnesium carbonate after adding water by the rotation of the stirring blade 6, the stirring blade 6 can move up and down, and can fully stir the basic magnesium carbonate, so that the basic magnesium carbonate material is fully in contact with water, thereby improving the washing effect, reducing the number and time of washing, and after the washing is completed, the washing wastewater is discharged in time through the vacuum filtration equipment.

[0048] It should be noted that the middle part of the stirring blade 6 is connected to the spline cylinder 5, and the connection method can be welding; the bottom of the washing tank 1 is a conical structure, and the drain outlet 13 is located at the lower end of the conical structure; the filter cloth filtering structure 3 is located near the large end of the conical structure. By setting the bottom of the washing tank 1 into a conical structure, on the one hand, it can play a role in guiding water, and on the other hand, it can reduce the amount of water stored at the bottom of the washing tank 1.

[0049] Since basic magnesium carbonate is insoluble in water, both the feed and discharge are transported in the form of slurry; that is, when the material is introduced into the washing tank 1 through the feed port 11, the material is introduced into the form of slurry; after washing is completed, water is added to the washing tank 1, and the material is stirred into a slurry by the stirring blade 6, and then the valve at the discharge port is opened to discharge the material.

[0050] In some embodiments, as Figures 1 to 12 As shown, the washing tank 1 includes a tank body 15 and a cover plate 16 , and the cover plate 16 is fixed to the tank body 15 via a flange.

[0051] In some embodiments, as Figures 1 to 12 As shown, the support component 8 has a through hole for the spline cylinder 5 to pass through, and the connecting member 7 includes a connecting sleeve, one end of which is connected to the output end of the driving member 2; the connecting sleeve passes through the top of the washing tank 1; wherein, the displacement component 9 and the support component 8 are both located in the connecting sleeve, the support component 8 and the connecting sleeve are relatively fixed, and the displacement component 9 and the connecting sleeve are slidably matched; the connecting sleeve can be welded to the output end of the driving member, and the connecting sleeve and the output end of the driving member can also be connected by a flange.

[0052] The support component 8 and the displacement component 9 are both cylindrical structures, and the support component 8, the displacement component 9 and the spline cylinder 5 are coaxially arranged; the displacement component 9 has a through hole on its outer peripheral wall, and the spline cylinder 5 has a threaded hole aligned with the through hole on the displacement component 9, and the spline cylinder 5 and the displacement component 9 are fixed by bolts; the through hole on the spline cylinder 5 is a countersunk hole, and the nut of the bolt is located in the countersunk hole to prevent the nut of the bolt from interfering with the rotation of the displacement component 9.

[0053] The displacement component 9 and the spline cylinder 5 can also be fixed by welding. Before welding the spline cylinder 5 and the displacement component 9, if the spline cylinder 5 is first welded and fixed to the stirring blade 6, it is necessary to first put the support component 8 on the spline cylinder 5, and then weld the displacement component 9 to the spline cylinder 5.

[0054] The support component 8 and the connecting sleeve can be fixed by bolts. Specifically, there is a through hole on the side wall of the connecting sleeve, and the support component 8 has a threaded hole aligned with the through hole on the connecting sleeve; after the support component 8 is placed into the connecting sleeve, the support component 8 is fixed to the connecting sleeve by bolts.

[0055] During the rotation of the displacement member 9, the inclined surface on the displacement member 9 is offset from the inclined surface on the support member 8. At this time, the inclined edge of the displacement member 9 contacts the inclined surface of the support member 8, allowing the displacement member 9 to move upward. When the displacement member 9 moves upward to the highest position, as the displacement member 9 continues to rotate, the displacement member 9 moves downward under the action of the gravity of the displacement member 9, the spline cylinder 5, and the stirring blade 6. After the displacement member 9 descends to the lowest position, as the displacement member 9 continues to rotate, the displacement member 9 can move upward. Through the above arrangement, the displacement member 9 can move up and down, thereby driving the stirring blade 6 to move up and down.

[0056] In some embodiments, as Figures 1 to 12 As shown, an elastic member 71 is further provided in the connecting sleeve, and both ends of the elastic member 71 abut against the inner top wall of the connecting sleeve and the top of the displacement member 9 respectively.

[0057] The elastic member 71 can be a spring, which can provide elastic force to the displacement component 9; when the displacement component 9 moves upward, the displacement component 9 compresses the spring; when the displacement component 9 moves from a high place to a low place, the spring elastic force is released; through the above arrangement, the stability of the up and down movement of the displacement component 9 can be improved.

[0058] In some embodiments, as Figures 1 to 12 As shown, the washing tank 1 has a pull-out opening 18 , and the filter cloth filtering structure 3 has a sealing layer at the position of the pull-out opening 18 ; wherein, the filter cloth filtering structure 3 can be pulled out of the washing tank 1 from the pull-out opening 18 .

[0059] The sealing layer is a rubber layer, which can press against the inner peripheral wall of the drawer opening 18 of the washing tank 1, thereby achieving a sealing effect.

[0060] The washing tank 1 is a circular structure, and a part of the filter cloth filtering structure 3 is located inside the washing tank 1 and contacts the inner wall of the washing tank 1; the other part is located outside the pull-out port 18; the washing tank 1 has a support frame 17 for supporting the filter cloth filtering structure 3; the support frame 17 provides support for the filter cloth filtering structure 3; the middle part of the support frame 17 is a through-hole structure, which can allow water to pass through without affecting the drainage function of the washing tank 1; through the above arrangement, after the filter cloth filtering structure 3 is placed in the washing tank 1, the stability of the filter cloth filtering structure 3 can be improved.

[0061] In some embodiments, as Figures 1 to 12 As shown, the filter cloth filtering structure 3 includes a filter plate 31 and a filter cloth 32. The portion of the filter plate 31 located in the washing tank 1 has a plurality of filter holes. The sealing layer is arranged at the position where the filter plate 31 contacts the draw-out port 18. The filter cloth 32 is arranged on the top of the filter plate 31. The filter cloth 32 covers the plurality of filter holes on the filter plate 31, and the filter cloth 32 is fixed on the filter plate 31. The filter plate 31 can act as a skeleton and can support the filter plate 31.

[0062] The filter plate 31 has a countersunk hole, which is a threaded hole. After the filter cloth 32 is placed on the top of the filter plate 31, the threaded end of the bolt passes through the filter cloth 32 and engages with the thread of the filter plate 31, thereby fixing the filter cloth 32 on the filter plate 31.

[0063] After the filter cloth 32 is fixed by bolts, the nuts of the bolts are located in the countersunk holes, preventing the nuts from protruding from the filter plate 31 , thereby preventing the nuts from affecting the sliding of the filter plate 31 on the washing tank 1 .

[0064] In some embodiments, as Figures 1 to 12 As shown, the outer side of the filter plate 31 has a first positioning hole 33, and the washing tank 1 is connected to a positioning block 19, and the positioning block 19 has a second positioning hole 191 aligned with the first positioning hole 33; wherein, the positioning block 19 is also provided with an L-shaped plate 14, and when the first positioning hole 33 and the second positioning hole 191 are aligned, the L-shaped plate 14 is plugged into and matched with the first positioning hole 33 and the second positioning hole 191 to locate the position of the filter plate 31.

[0065] After the filter plate 31 is inserted into place, the first positioning hole 33 on the filter plate 31 is aligned with the second positioning hole 191 on the positioning block 19. At this time, the L-shaped plate 14 is plugged into and matched with the first positioning hole 33 and the second positioning hole 191, which can limit the filter plate 31 and prevent the filter plate 31 from slipping out of the washing tank 1.

[0066] In some embodiments, as Figures 1 to 12As shown, the washing equipment also includes a support frame 10, and the washing tank 1 is installed on the support frame 10; a lifting frame 1001 is provided on the support frame 10 for sliding along the height direction, and a lifting component 1002 is provided between the support frame 10 and the lifting frame 1001; wherein, the driving member 2 is connected to the lifting frame 1001.

[0067] The support frame 10 has a support column 1003, and the support column 1003 has a guide groove 1004. The side of the lifting frame 1001 is connected to a guide block 1005 that slides with the guide groove 1004; by lifting the support frame 10 through the lifting component 1002, the driving member 2 can be driven to move upward, and then the stirring blade 6 can be driven to move upward.

[0068] In the initial position, the driving member 2 and the stirring blade 6 are both located at a high position; after the material and water are put into the washing tank 1, the stirring blade 6 follows the driving member 2 to move downward to the stirring position. At this time, the position of the driving member 2 remains unchanged. In the process of the driving member 2 driving the stirring blade 6 to rotate, the stirring blade 6 can simultaneously move back and forth along the axial direction, so as to fully stir the material.

[0069] After the stirring is completed, the stirring blade 6 moves upward to a high position following the driving member 2, and then the waste water is filtered; after the filtration is completed, water is added to the washing tank 1 again, and then the stirring blade 6 moves downward to the stirring position to continue stirring the material; the above process is repeated.

[0070] In some embodiments, as Figures 1 to 12 As shown, the lifting component 1002 includes a hydraulic cylinder, and the outer end of the piston rod of the hydraulic cylinder has an external thread; wherein, one side of the lifting frame 1001 has a connecting groove 1006, and the connecting groove 1006 has a connecting block 1007, and the bottom of the connecting block 1007 has a threaded hole that matches the piston rod thread; the bottom wall of the connecting groove 1006 has a through hole for the piston rod to pass through.

[0071] When the piston rod is connected to the lifting frame 1001, the connecting block 1007 is first placed into the connecting groove 1006 with the threaded hole on the connecting block 1007 facing downward; then the piston rod is inserted into the connecting groove 1006 and threadedly connected to the connecting block 1007. Through the above arrangement, the piston rod can be connected to the connecting block 1007, so when the piston rod is extended or retracted, it can drive the lifting frame 1001 to move up and down.

[0072] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
