Description

Technical Field

[0001] The invention relates to the field of sludge treatment, and more specifically to a sludge solidifying agent stirring and conveying device. Background Art

[0002] The long-term random stacking of sludge occupies a large amount of land and reduces the efficiency of land resource utilization; it emits foul-smelling gases, affecting the living environment of surrounding residents; at the same time, the leachate produced by the stacking of sludge will pollute the soil and groundwater environment. Reducing, harmlessly treating and recycling the existing sludge is not only an important measure to implement the relevant environmental protection requirements of the Ministry of Environmental Protection and the Provincial Environmental Protection Department, but also an objective requirement to completely eliminate the environmental risks brought about by it and optimize the overall environment of the region;

[0003] Sludge solidifier is the main chemical material used in sludge solidification technology for sludge pre-landfill treatment. After solidification treatment, the unconfined compressive strength of the sludge solidified body is increased, the water content is reduced, the leachate is reduced, and the treated solidified body is easier to handle and transport than the original sludge.

[0004] A Chinese patent with authorization announcement number CN215822952U discloses a novel stirring and conveying device for a sludge solidifying agent.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0046] See also Figures 1 to 12 A sludge solidifying agent stirring and conveying device comprises a stirring bin 1, an upper cover 2 is fixedly connected to the upper surface of the stirring bin 1, a closing valve 8 is fixedly connected to the lower surface of the stirring bin 1, a spiral feeding cylinder 3 is fixedly connected to the bottom of the closing valve 8, a second driving motor 9 is fixedly connected to one side of the spiral feeding cylinder 3, a discharge port 4 is connected to the outer surface of the spiral feeding cylinder 3, a first driving motor 7 is fixedly connected to the middle of the upper surface of the upper cover 2, a stirring shaft 10 is fixedly connected to the output end of the first driving motor 7, a scraping assembly 5 for cleaning the residual material inside the stirring bin 1 is connected to the lower surface of the upper cover 2, and a speed reduction assembly 6 is connected to the edge of the upper surface of the upper cover 2.

[0047] like Figure 3 - Figure 5 As shown, the scraping assembly 5 includes a speed regulating motor 51 fixedly connected to one side of the upper surface of the upper cover 2 and a fixed sleeve rod 53 fixed to the lower surface of the upper cover 2, the fixed sleeve rod 53 is slidably connected to the inside of the telescopic assembly 55, and a triangular plate 54 is provided on one side of the telescopic assembly 55. The output end of the speed regulating motor 51 is fixedly connected to the second threaded rod 52, the outer surface of the second threaded rod 52 is threadedly connected to the internal threaded sleeve block 59, the outer surface of the internal threaded sleeve block 59 is slidably connected to the swing ring 57, the inner side of the swing ring 57 is provided with an arc groove 510, and the inner surface of the arc groove 510 is fixedly connected to the first spring 511, the lower surface of the swing ring 57 is provided with a fitting cleaning assembly 56, and the upper surface of the swing ring 57 is provided with a second through groove 58.

[0048] The bottom of the fixed sleeve 53 passes through the interior of the second through groove 58 and slides with each other. The internal thread sleeve block 59 is located inside the arc groove 510 and slides. One side of the first spring 511 is fixedly connected to one side of the internal thread sleeve block 59. The stirring shaft 10 is located inside the stirring chamber 1, and a feed port is provided on the upper surface of the upper cover 2.

[0049] After several times of stirring and production, some sludge solidifying agent raw materials will adhere to the inner wall of the stirring bin 1, which needs to be processed and collected in time to reduce the waste and deterioration of materials. At this time, it is necessary to turn on the speed regulating motor 51 to drive the second threaded rod 52 to rotate. The second threaded rod 52 drives the internal threaded sleeve block 59 to move downward under the action of the thread. The internal threaded sleeve block 59 pushes the swing ring 57 to move downward, and the swing ring 57 slides downward along the outer surface of the triangular plate 54. When the swing ring 57 contacts the upper bevel of the triangular plate 54 on the surface, the swing ring 57 will slide along the bevel of the triangular plate 54 and rotate the moving distance, and the internal threaded sleeve block 59 will slide relatively inside the arc groove 510, pressing the first spring 511. The swing ring 57 is compressed and the triangular plate 54 enters the second through groove 58. After the swing ring 57 passes through the upper bevel of the triangular plate 54, it will move in the opposite direction along the lower bevel of the triangular plate 54 under the elastic force of the first spring 511. After passing through the triangular plate 54, it will continue to move downward along the fixed sleeve rod 53, so that the swing ring 57 swings left and right at the same time while moving, and cleans the residual material from different directions, so that the bonding cleaning component 56 can clean the adhesion on the side wall of the mixing bin 1 more thoroughly, and the swing ring 57 can swing back and forth to throw off the material adhered to the bonding cleaning component 56, so as to ensure the relative cleanliness of the bonding cleaning component 56 and reduce the residue inside the bonding cleaning component 56.

[0050] like Figure 6 and Figure 7 As shown, the telescopic assembly 55 includes a telescopic rod 551 slidably connected to the inside of the fixed sleeve rod 53, a first through groove 555 opened on one side of the fixed sleeve rod 53 and a disc 554 fixed to the outer surface of the second threaded rod 52, two trapezoidal plates 553 are fixedly connected to the edge of the upper surface of the disc 554, three sliders 556 are fixedly connected to one side of the telescopic rod 551, one side of the slider 556 is fixedly connected to one side of the triangular plate 54, and a contact plate 552 is fixedly connected to the side of the telescopic rod 551 close to the disc 554.

[0051] The slider 556 slides inside the first through groove 555 , the disc 554 is located above the upper cover 2 , the top of the telescopic rod 551 passes through the interior of the upper cover 2 and slides with each other, the contact plate 552 is located above the disc 554 , and inclined surfaces are provided on both sides of the contact plate 552 .

[0052] Although the swing ring 57 can swing back and forth through the cooperation between the second through groove 58 and the triangular plate 54, the triangular plate 54 is in a fixed state and the swing ring 57 will always move along a certain motion trajectory. During the movement, there will be a gap between the cleaning components 56 that fit together, resulting in the area at the gap being unable to be cleaned, resulting in a partial area inside the mixing chamber 1 being unable to be cleaned, resulting in a poor cleaning effect. Therefore, a disc 554 is provided on the outer side of the second threaded rod 52. When the second threaded rod 52 rotates, it can drive the trapezoidal plate 553 to move in a circle. The hypotenuse of the trapezoidal plate 553 contacts the hypotenuse of the contact plate 552, and the movement of the trapezoidal plate 553 will The contact plate 552 is lifted upward, driving the telescopic rod 551 to move upward inside the fixed sleeve rod 53. When the trapezoidal plate 553 passes through the contact plate 552, the telescopic rod 551 moves downward under the action of its own weight. The telescopic rod 551 moving up and down drives the triangular plate 54 to slide on the outside of the fixed sleeve rod 53 through the slider 556, and the speed regulating motor 51 can change speed, so that the position of the triangular plate 54 is not fixed and regular, so that the position of the swing ring 57 is not fixed when passing through the triangular plate 54, and the height when it starts to swing is irregular, so that every corner is cleaned, thereby making up for the disadvantage that the distance between the cleaning components 56 cannot be cleaned, and the cleaning is more efficient and the effect is better.

[0053] like Figure 5 As shown, the cleaning assembly 56 includes four grooves 562 evenly arranged on the lower surface of the swing ring 57, two fourth springs 563 are fixedly connected to one side of the inner surface of the grooves 562, and an arc-shaped brush 561 is fixedly connected to one side of the two fourth springs 563.

[0054] The arc-shaped brush 561 is located inside the groove 562 and slidably fits therein, and one side of the arc-shaped brush 561 is in contact with the inner surface of the mixing chamber 1 .

[0055] As the arc-shaped brush 561 continuously cleans and wipes the inner wall of the mixing chamber 1, the arc-shaped brush 561 will be worn to a certain extent, causing the arc-shaped brush 561 to be unable to fit tightly against the inside of the mixing chamber 1, and the material adhering to the inner wall of the mixing chamber 1 cannot be cleaned. Therefore, when the arc-shaped brush 561 is installed, it is installed through the fourth spring 563, and the fourth spring 563 is in a compressed state, so that the elastic force generated by the fourth spring 563 is applied to the arc-shaped brush 561, so that the arc-shaped brush 561 fits against the inner wall of the mixing chamber 1 with a certain pressure, thereby improving the cleaning power, and when the arc-shaped brush 561 is worn, the arc-shaped brush 561 can be continuously pushed to ensure that the arc-shaped brush 561 always fits against the inner wall of the mixing chamber 1.

[0056] like Figure 8 - Fig.10As shown, the reduction assembly 6 includes a first pinion 61 fixed on the outer surface of the stirring shaft 10, a first large gear 62 rotating on the upper surface of the upper cover 2, a spline shaft 65 rotating at the edge of the upper surface of the upper cover 2, and a first L-shaped plate 67 fixedly connected to one side of the upper surface of the upper cover 2, a second pinion 63 fixedly connected to the upper surface of the first large gear 62, a second large gear 64 sleeved on the outer surface of the spline shaft 65, a first threaded rod 611 fixedly connected to the top of the second large gear 64, an inner threaded sleeve 69 threadedly connected to the outer surface of the first threaded rod 611, a limiting plate 610 fixedly connected to the outer surface of the inner threaded sleeve 69, a control switch 612 fixedly connected to the lower surface of the first L-shaped plate 67 near the inner threaded sleeve 69, and a second L-shaped plate 68 fixedly connected to one side of the inner threaded sleeve 69.

[0057] The top of the internal threaded sleeve 69 passes through the interior of the first L-shaped plate 67, the limit plate 610 is located at the top of the first L-shaped plate 67, the two control switches 612 respectively control the opening and closing of the closing valve 8 and the second drive motor 9, the first large gear 62 and the first small gear 61 are meshed with each other, the second small gear 63 and the second large gear 64 are meshed with each other, the second large gear 64 and the spline shaft 65 slide with each other, and a trigger assembly 66 is provided on the lower surface of the first L-shaped plate 67.

[0058] It takes a certain amount of time to stir the sludge solidifying agent, that is, a cycle required for the sludge solidifying agent to be completely stirred. After the cycle is completed, the material inside the stirring bin 1 needs to be transported to the inside of the spiral feeding cylinder 3 in time to avoid delaying the work efficiency. It is necessary to manually and accurately control the time, but manual operation and timely processing are not possible. The longer the delay, the lower the production efficiency.

[0059] To this end, when the first driving motor 7 drives the stirring shaft 10 to rotate to stir the material inside the stirring bin 1, the stirring shaft 10 drives the first pinion 61 to rotate, the first pinion 61 drives the first large gear 62 and the second pinion 63 to rotate, the second pinion 63 drives the second large gear 64 to rotate, and the speed reduction operation is performed through the transmission ratio of the large and small gears, so that the larger the transmission ratio of the first pinion 61 and the second large gear 64, the greater the first pinion 61 rotates a certain number of circles in one cycle, and the second large gear 64 rotates a certain number of circles, the second large gear 64 drives the first threaded rod 611 to rotate a certain number of circles through the spline shaft 65, and the first threaded rod 611 drives the internal threaded sleeve 69 to move upward, The internal threaded sleeve 69 drives the second L-shaped plate 68 to move upward. When the second L-shaped plate 68 squeezes the control switch 612, the closing valve 8 and the second drive motor 9 are opened at the same time to work. The material enters the interior of the spiral feeding barrel 3 through the closing valve 8. The second drive motor 9 drives the spiral shaft inside the spiral feeding barrel 3 to work to convey the material, so that the material is stirred and conveyed in time to avoid delays in the material, thereby greatly improving work efficiency. When the internal threaded sleeve 69 is reset, the second large gear 64 is lifted to disengage the second small gear 63, and the second large gear 64 is rotated in the opposite direction to drive the internal threaded sleeve 69 to reset. The limit plate 610 and the first L-shaped plate 67 are fitted and reset to complete.

[0060] like Fig.11 and Fig.12 As shown, the trigger assembly 66 includes a fixed plate 668 fixed to the lower surface of the first L-shaped plate 67, an L-shaped pressing plate 662 sliding inside the first L-shaped plate 67, a trapezoidal block 669 sliding inside the second L-shaped plate 68, and a variable speed motor switch 661 fixed on the top of the first L-shaped plate 67, one side of the trapezoidal block 669 is fixedly connected to a connecting plate 6611, one side of the connecting plate 6611 is fixedly connected to a third spring 6610, the interior of the fixed plate 668 is slidably connected to a pull rod 667, one side of the pull rod 667 is fixedly connected to a second thorn rack 665, the outer surface of the pull rod 667 is sleeved with a second spring 666, and the two sides of the L-shaped pressing plate 662 are respectively fixedly connected to a first thorn rack 664 and a plurality of triangular blocks 663.

[0061] The second thorn rack 665 and the first thorn rack 664 are meshed with each other, and one side of the third spring 6610 is fixedly connected to one side of the second L-shaped plate 68 .

[0062] After the material is mixed, the residual material on the inner wall of the mixing bin 1 needs to be cleaned regularly. When the second L-shaped plate 68 moves up, it drives the trapezoidal block 669 to move up. When the hypotenuse of the trapezoidal block 669 contacts the hypotenuse of the triangular block 663, the trapezoidal block 669 contracts and passes through a triangular block 663. When the second L-shaped plate 68 moves down, the right-angled side of the trapezoidal block 669 contacts the right-angled side of the triangular block 663 and drives the L-shaped pressing plate 662 to move down a certain distance. As the L-shaped pressing plate 662 moves down, the first The thorn rack 664 can move smoothly to one side of the second thorn rack 665, but cannot move upward. When the second L-shaped plate 68 moves upward again, it will drive the L-shaped pressing plate 662 to move down a certain distance through the triangular block 663. After a certain number of times, the L-shaped pressing plate 662 squeezes the speed motor switch 661 to turn on the speed regulating motor 51 to work. After the end, pull the pull rod 667 to drive the second thorn rack 665 and the first thorn rack 664 to separate from each other, and reset the L-shaped pressing plate 662 again.

At the same time, the trapezoidal plate 553 and the contact plate 552 cooperate, and the telescopic rod 551 moves up and down, and the triangular plate 54 is driven to slide on the outside of the fixed sleeve rod 53 through the slider 556, and the speed regulating motor 51 can change speed, so that the position of the triangular plate 54 is not fixed and regular, so that the position of the swinging ring 57 when passing through the triangular plate 54 is not fixed, and the height when it starts to swing is irregular, so that every corner is cleaned, and under the action of the fourth spring 563, the arc brush 561 is always fitted with the inner wall of the mixing bin 1, which can make up for the loss caused by the friction of the arc brush 561;

[0064] Then, the deceleration operation is performed through the transmission ratio of the large and small gears, so that the larger the transmission ratio of the first small gear 61 and the second large gear 64, the first small gear 61 rotates a certain number of times in one cycle, and the second large gear 64 rotates a certain number of times, and the second large gear 64 drives the first threaded rod 611 to rotate a certain number of times through the spline shaft 65, the first threaded rod 611 drives the internal threaded sleeve 69 to move upward, and the internal threaded sleeve 69 drives the second L-shaped plate 68 to move upward, when the second L-shaped plate 68 squeezes the control switch 612, the closing valve 8 is opened and the second drive motor 9 is operated at the same time, the material enters the interior of the spiral feeding barrel 3 through the closing valve 8, the second drive motor 9 drives the spiral shaft inside the spiral feeding barrel 3 to work, and the material is transported in time, in each mixing cycle, the trapezoidal block 669 drives the L-shaped pressing plate 662 to move down a certain distance through the triangular block 663, after several cycles, the L-shaped pressing plate 662 squeezes the variable speed motor switch 661, turns on the speed regulating motor 51 to energize, and cleans the inside of the mixing bin 1.
