Description

Technical Field

[0001] The present invention relates to the technical field of solid waste saw mud treatment, and in particular to a solid waste saw mud treatment device and application thereof. Background Art

[0002] Solid waste sawdust is waste generated during the stone cutting and processing process. It is mainly composed of fine stone powder particles and water, and has the characteristics of fine texture, high water content, and high viscosity. When cutting stones, stone processing plants will produce a large amount of sawdust, especially in the processing of hard stones such as granite. The solid particles and liquid in the sawdust can be separated and processed to obtain solid particles, and then through pressing, molding and other processes to produce resource products such as building materials for recycling.

[0003] After searching, the invention patent with Chinese patent number CN115382276A discloses a multi-effect combined mud-water separation system for dredging sludge. Compared with the prior art, the invention patent with Chinese patent number CN115382276A is provided with a lifting dredging device, in which the sludge is continuously transported upward by the conveying mechanism and is continuously pumped away by the sludge pump, thereby improving the sludge pumping efficiency by reducing the resistance of the sludge. At the same time, the lifting mechanism is used to control the descent depth of the mud entry barrel according to different needs, thereby facilitating the control of the sludge extraction depth; the problem of using more vibration motors working at the same time, which will generate greater noise and energy consumption during the operation, is solved.

[0004] However, during actual use of the above-mentioned device, the vibrating screening mechanism is used to vibrate the mud on the screen, but the mud is constantly in contact with the screen. When the solid particles in the mud swing or flow back and forth on the screen, the smaller particles will accumulate on the screen holes to form a thick particle layer, thereby blocking the screen holes, and when filtering through the inclined screen, part of the water flow in the mud may flow to the outside of the box along with the solid particles, resulting in a higher water content in the solid part. Therefore, a solid waste saw mud treatment device and its application are proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art that the screen is easily blocked and part of the water flow in the mud may flow to the outside of the box together with the solid particles, resulting in a higher water content in the solid part, and to propose a solid waste saw mud processing device and its application.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A solid waste saw mud processing device comprises a box body, a feeding port is installed on the upper part of the box body, a primary processing chamber, a storage chamber, a secondary processing chamber and a first square groove are respectively opened on the inner side of the box body, a primary processing component is jointly arranged on the box body and the primary processing chamber, and the primary processing component comprises a first servo motor installed on the side of the box body, a first filter screen and a second filter screen movably connected to the inner side of the primary processing chamber, and two blowers installed on the side of the box body, and connecting pipes installed on the first filter screen and the second filter screen, the connecting pipe is fixedly connected to the blower, and the inner sides of the first filter screen and the second filter screen are each provided with a second square groove, Two pressure rods are installed on the inner side of the primary processing chamber. After the first servo motor is started, it drives the first filter screen and the second filter screen to rotate back and forth. When the first filter screen and the second filter screen rotate back and forth, they squeeze the pressure rod, and the force generated by squeezing the pressure rod causes the first filter screen and the second filter screen to move back and forth. After the blower is started, the wind force generated is blown into the second square groove through the connecting pipe, and the wind force in the second square groove drives the solid particles to be discharged through the holes of the first filter screen and the second filter screen, which can ensure that the first filter screen and the second filter screen always maintain the best separation effect and will not interrupt the separation process due to blockage.

[0008] The box body and the secondary processing chamber are jointly provided with a secondary processing component, and the secondary processing component includes a first gear and a second gear rotatably connected to the side of the box body, a threaded rod rotatably connected to the inner side of the secondary processing chamber, and an extrusion plate slidably arranged on the inner side of the secondary processing chamber, the extrusion plate and the threaded rod are threadedly connected, and a third filter screen is installed on the side of the box body. After the first servo motor is started, the threaded rod is driven to rotate back and forth through the first gear and the second gear. The force generated by the back and forth rotation of the threaded rod drives the extrusion plate to move back and forth. The back and forth movement of the extrusion plate continuously squeezes the solid waste saw mud in the secondary processing chamber, so that the water flow in the solid waste saw mud is discharged to the outside of the box body through the third filter screen, further removing the residual moisture in the solid waste saw mud, making the solid particles drier. This continuous separation process greatly improves the overall separation efficiency.

[0009] The above technical solution further includes:

[0010] The side surfaces of the box body are rotatably connected with a first rotating rod and a second rotating rod, a second transmission belt is commonly sleeved between the first rotating rod and an output end of the first servo motor, a first transmission belt is commonly sleeved between the second rotating rod and an output end of the first servo motor, and the first servo motor drives the second rotating rod and the first rotating rod to rotate back and forth respectively through the first transmission belt and the second transmission belt.

[0011] The ends of the first rotating rod and the second rotating rod extending to the inner side of the primary processing chamber are both equipped with movable rods, and the sides of the first filter screen and the second filter screen are both provided with sliding grooves, and the sides of the two movable rods are both equipped with sliding blocks, and the sliding blocks are slidably arranged on the inner side of the sliding grooves, and the sides of the sliding blocks are equipped with springs, and the end of the spring away from the sliding block is fixedly connected to the inner wall of the sliding groove, so that the first filter screen and the second filter screen are displaced through the sliding groove and the sliding block respectively.

[0012] The cross section of the compression rod is trapezoidal, and the two compression rods are respectively located on the movement tracks of the first filter screen and the second filter screen. The first filter screen and the second filter screen can squeeze the compression rod when they rotate back and forth.

[0013] A first drain outlet is provided on the side of the box body, and a second drain outlet is provided on the side of the box body away from the first drain outlet. The first drain outlet and the second drain outlet are both connected to the primary processing chamber, and the separated water flow is discharged to the outside of the box body through the second drain outlet and the first drain outlet.

[0014] The inner side of the box body is rotatably connected to a first baffle, and a second servo motor is installed on the side of the box body. The output end of the second servo motor extending inside the box body is fixedly connected to the first baffle. The storage cavity is opened and closed by starting the second servo motor to drive the first baffle to rotate.

[0015] The inner side of the box body is rotatably connected to a second baffle, and a third servo motor is installed on the side of the box body. The output end of the third servo motor extending to the inner side of the box body is fixedly connected to the second baffle. The second baffle is driven to rotate by starting the third servo motor to realize the opening and closing of the secondary processing chamber.

[0016] The first gear is rotatably connected to a side of the box body close to the first servo motor, and a third transmission belt is jointly sleeved between the first gear and the output end of the first servo motor. The side of the box body is rotatably connected to a third rotating rod, and the third rotating rod is fixedly connected to the second gear. The first gear is meshed with the second gear.

[0017] The size of the secondary processing chamber opening is matched with the size of the extrusion plate, so that the extrusion plate can ensure sealing when extruding the solid waste saw mud.

[0018] An application method of a solid waste saw mud processing device comprises the following steps:

[0019] Step 1: The solid waste saw mud is put into the box through the feed port, first enters the first filter screen in the primary processing chamber, and is initially separated and processed by the first filter screen, and then flows to the second filter screen through the inclined surface of the first filter screen, and is separated and processed again by the second filter screen;

In the present invention, by setting a primary processing component, when the solid-liquid separation processing of solid waste saw mud is realized through the first filter screen and the second filter screen, the real-time rotation and displacement of the first filter screen and the second filter screen can be realized, and then the gas is blown into the holes of the first filter screen and the second filter screen, so as to drive the solid particles blocked in the holes to be discharged to the upper part of the first filter screen and the second filter screen. The above-mentioned combined use can ensure that the first filter screen and the second filter screen always maintain the best separation effect, and the separation processing work will not be interrupted due to blockage.

[0024] 2.

When the first filter screen 8 and the second filter screen 9 rotate back and forth, they squeeze the pressure rod 19, and the force generated by squeezing the pressure rod 19 causes the first filter screen 8 and the second filter screen 9 to move back and forth. After the blower 20 is started, the wind force generated is blown into the second square groove 21 through the connecting pipe 10, and the wind force in the second square groove 21 drives the solid particles to be discharged through the holes of the first filter screen 8 and the second filter screen 9, which can ensure that the first filter screen 8 and the second filter screen 9 always maintain the best separation effect, and the separation processing work will not be interrupted due to blockage;

[0036] The housing 1 and the secondary processing chamber 13 are jointly provided with a secondary processing component, which includes a first gear 28 and a second gear 31 rotatably connected to the side of the housing 1, a threaded rod 33 rotatably connected to the inner side of the secondary processing chamber 13, and an extrusion plate 35 slidably arranged on the inner side of the secondary processing chamber 13. The extrusion plate 35 is threadedly connected to the threaded rod 33. A third filter screen 36 is installed on the side of the housing 1. After the first servo motor 7 is started, the threaded rod 33 is driven to rotate back and forth through the first gear 28 and the second gear 31. The force generated by the back and forth rotation of the threaded rod 33 drives the extrusion plate 35 to move back and forth. The back and forth movement of the extrusion plate 35 continuously squeezes the solid waste saw mud in the secondary processing chamber 13, so that the water flow in the solid waste saw mud is discharged to the outside of the housing 1 through the third filter screen 36, further removing the residual moisture in the solid waste saw mud and making the solid particles drier. This continuous separation process greatly improves the overall separation efficiency.

[0037] The side surfaces of the box body 1 are rotatably connected with the first rotating rod 3 and the second rotating rod 4 respectively. A second transmission belt 6 is commonly sleeved between the first rotating rod 3 and the output end of the first servo motor 7. A first transmission belt 5 is commonly sleeved between the second rotating rod 4 and the output end of the first servo motor 7. The first servo motor 7 drives the second rotating rod 4 and the first rotating rod 3 to rotate back and forth respectively through the first transmission belt 5 and the second transmission belt 6.

[0038] The ends of the first rotating rod 3 and the second rotating rod 4 extending to the inner side of the primary processing chamber 11 are both equipped with movable rods 15, and the sides of the first filter screen 8 and the second filter screen 9 are both provided with sliding grooves 16. The sides of the two movable rods 15 are both equipped with sliding blocks 17, and the sliding blocks 17 are slidably arranged on the inner side of the sliding groove 16. The side of the sliding block 17 is equipped with a spring 18, and the end of the spring 18 away from the sliding block 17 is fixedly connected to the inner wall of the sliding groove 16, so that the first filter screen 8 and the second filter screen 9 are displaced through the sliding groove 16 and the sliding block 17 respectively.

[0039] The cross section of the pressure rod 19 is trapezoidal. The two pressure rods 19 are respectively located on the movement tracks of the first filter screen 8 and the second filter screen 9. The first filter screen 8 and the second filter screen 9 can squeeze the pressure rod 19 when they rotate back and forth.

[0040] A first drain port 22 is provided on the side of the box body 1, and a second drain port 23 is provided on the side of the box body 1 away from the first drain port 22. Both the first drain port 22 and the second drain port 23 are connected to the primary treatment chamber 11, and the separated water flow is discharged to the outside of the box body 1 through the second drain port 23 and the first drain port 22.

[0041] In this embodiment, the solid waste saw mud is put into the box body 1 through the feed port 2, and first moves to the first filter screen 8 in the primary processing chamber 11, and is preliminarily separated and processed by the first filter screen 8. At this time, the preliminarily separated water flow is discharged to the outside of the box body 1 through the second drain port 23, and then the remaining solid waste saw mud continues to flow through the inclined surface of the first filter screen 8 to the second filter screen 9, and is separated and processed again by the second filter screen 9. At this time, the separated water flow is discharged to the outside of the box body 1 through the first drain port 22, and during separation, the water flow can first enter the inner side of the second square groove 21, and then be discharged to the outside of the first filter screen 8 and the second filter screen 9. At the same time, the first servo motor 7 can be started to rotate the output shaft of the first servo motor 7 back and forth, and at the same time, the first transmission belt 22 is used to transmit the water flow to the outside of the box body 1. 5 and the second transmission belt 6 respectively drive the second rotating rod 4 and the first rotating rod 3 to rotate back and forth. When the second rotating rod 4 and the first rotating rod 3 rotate back and forth, they respectively drive the first filter screen 8 and the second filter screen 9 to rotate back and forth through the movable rod 15. When the first filter screen 8 and the second filter screen 9 rotate back and forth, they can squeeze the inclined surface of the pressure rod 19. The force generated by the squeezing causes the first filter screen 8 and the second filter screen 9 to move through the sliding groove 16 and the sliding block 17 respectively, and the spring 18 contracts at the same time. When the first filter screen 8 and the second filter screen 9 move to the other side of the pressure rod 19 respectively, the spring 18 in the contracted state at this time is reset, and at the same time drives the first filter screen 8 and the second filter screen 9 to reset, so that the first filter screen 8 and the second filter screen 9 are displaced back and forth while the first filter screen 8 and the second filter screen 9 rotate back and forth;

[0042] At the same time, the blower 20 can be started, the blower 20 generates gas and blows the gas through the connecting pipe 10 to the second square groove 21 inside the first filter 8 and the second filter 9, and then discharges the gas through the holes of the first filter 8 and the second filter 9, and at the same time drives the solid particles blocked in the holes to be discharged to the upper part of the first filter 8 and the second filter 9, so as to realize the real-time rotation and displacement of the first filter 8 and the second filter 9, and then blows the gas into the holes of the first filter 8 and the second filter 9. The above-mentioned combined use can ensure that the first filter 8 and the second filter 9 always maintain the best separation effect, and the separation process will not be interrupted due to blockage.

[0043] Embodiment 2

[0044] like Figure 1-Figure 7 As shown, based on the first embodiment, the inner side of the box body 1 is rotatably connected to the first baffle 24, and the side of the box body 1 is installed with a second servo motor 25. The output end of the second servo motor 25 extending inside the box body 1 is fixedly connected to the first baffle 24. By starting the second servo motor 25 to drive the first baffle 24 to rotate, the storage cavity 12 is opened and closed.

[0045] The inner side of the box body 1 is rotatably connected to a second baffle 26, and a third servo motor 27 is installed on the side of the box body 1. The third servo motor 27 extends to the output end inside the box body 1 and is fixedly connected to the second baffle 26. By starting the third servo motor 27 to drive the second baffle 26 to rotate, the opening and closing of the secondary processing chamber 13 is realized.

[0046] The first gear 28 is rotatably connected to a side of the box body 1 close to the first servo motor 7, and a third transmission belt 29 is commonly sleeved between the first gear 28 and the output end of the first servo motor 7. A third rotating rod 30 is rotatably connected to the side of the box body 1, and the third rotating rod 30 is fixedly connected to the second gear 31, and the first gear 28 is meshed with the second gear 31. The third rotating rod 30 extends to one end of the inner side of the secondary processing chamber 13 and is equipped with a first bevel gear 32. A second bevel gear 34 is installed on the outer side of the threaded rod 33, and the second bevel gear 34 is meshed with the first bevel gear 32. The solid waste saw mud in the secondary processing chamber 13 is continuously squeezed by the back and forth movement of the extrusion plate 35.

[0047] The size of the opening of the secondary processing chamber 13 is matched with the size of the squeezing plate 35 so that the squeezing plate 35 can ensure sealing when squeezing the solid waste saw mud.

[0048] In this embodiment, after the solid waste saw mud passes through the first filter screen 8 and the second filter screen 9 for separation, the remaining solid waste saw mud can be discharged into the storage chamber 12 through the first square groove 14, and then the second servo motor 25 is started, and the first baffle 24 is driven to rotate by the second servo motor 25, so that the solid waste saw mud in the storage chamber 12 can flow into the secondary processing chamber 13. When the secondary processing chamber 13 is filled with solid waste saw mud, the second servo motor 25 can be started, and then the first baffle 24 is driven to reset to block the opening of the storage chamber 12. At this time, the separated solid waste saw mud flows into the storage chamber 12 for temporary storage. At the same time, when the first servo motor 7 is started, the first gear 28 can be driven to rotate back and forth through the third transmission belt 29. Since the second gear 31 is meshed with the first gear 28, the first gear 28 is meshed with the second gear 31. When the wheel 28 rotates, it can drive the second gear 31 to rotate back and forth, and at the same time drive the third rotating rod 30 to rotate. Since the first bevel gear 32 and the second bevel gear 34 are meshed, when the third rotating rod 30 rotates, the first bevel gear 32 and the second bevel gear 34 can drive the threaded rod 33 to rotate back and forth. The force generated when the threaded rod 33 rotates back and forth can drive the extrusion plate 35 to move back and forth. The back and forth movement of the extrusion plate 35 continuously squeezes the solid waste saw mud in the secondary processing chamber 13, so that the water flow in the solid waste saw mud passes through the third filter screen 36 and is discharged to the outside of the box body 1. Then the third servo motor 27 can be started, and the second baffle 26 can be driven to rotate at the same time, so that the remaining solid waste saw mud is discharged through the opening of the secondary processing chamber 13, which can further remove the residual moisture in the solid particles and make the solid particles drier. This continuous separation process greatly improves the overall separation efficiency, so that the water content of the solid part of the treated solid waste saw mud is lower.
