DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 8 As shown, the present invention includes the following embodiments:

[0031] Embodiment 1: A landscaping waste drying treatment equipment, comprising a collecting trough 11 which is arranged through the front and rear of a box body 1; the middle section of the collecting trough 11 passes through the upper surface of the box body 1 upward; the collecting box 2 with an opening facing upward is connected to the front and rear sliding seals in the collecting trough 11; the front and rear sides of the upper surface of the box body 1 are fixedly connected to the supporting blocks 12; the front and rear two supporting blocks 12 are rotatably connected to the driving rollers 13; the number of the driving rollers 13 is two; the two driving rollers 13 rollingly support the sludge barrel 3; the outer wall of one of the supporting blocks 12 is fixedly connected to the first motor 1 4; the output shaft of the first motor 14 is fixedly connected to one of the driving rollers 13; the rotation of the driving roller 13 can drive the sludge barrel 3 to rotate; the opening of the sludge barrel 3 faces the front side; the inner and outer walls of the sludge barrel 3 are penetrated by a dewatering groove 31; there are multiple dewatering grooves 31; the multiple dewatering grooves 31 are evenly distributed around the arc-shaped outer wall of the sludge barrel 3; the dewatering cloth 32 is fixedly connected to the dewatering groove 31; the dewatering cloth 32 is fixedly connected to the dewatering groove 31 near the inner side of the sludge barrel 3; the inner bottom wall of the sludge barrel 3 is penetrated by a vent 41.

[0032] In this embodiment, the upper surface of the box body 1 is fixedly connected to the arch cover 5; the sludge barrel 3 is located inside the arch cover 5; the width of the sludge barrel 3 in the front-to-back direction is greater than the length of the dewatering cloth 32 in the front-to-back direction.

[0033] During operation, the staff pours the landscaping waste, i.e., the sludge, into the inner side of the sludge barrel 3 along the opening of the sludge barrel 3. The sludge is located at the lower inner side of the sludge barrel 3 under the action of gravity. Then, the staff controls the first motor 14 to rotate. The rotating first motor 14 drives one of the driving rollers 13 to rotate. The driving roller 13 is composed of a driving rod in the middle and driving wheels at both ends. The rotation of one of the driving rollers 13 drives the supported sludge barrel 3 to rotate. During the rotation of the sludge barrel 3, the dewatering cloth 32 on the arc-shaped outer wall is driven to rotate around the center of the sludge barrel 3. The free water in the sludge passes through the dewatering cloth 32 under the action of gravity. The free water flowing out from the dewatering cloth 32 will fall into the collecting box 2 in the collecting tank 11 for collection. During the rotation of the sludge barrel 3, the sludge at the lower position of the inner side of the sludge barrel 3 will be lifted up, and the sludge will adhere to the inner wall of the sludge barrel 3. The surrounding airflow will flow along the opening of the sludge barrel 3, the inner side of the sludge barrel 3 and the air vent 41, so as to air-dry the sludge on the inner wall of the sludge barrel 3. Compared with the flat-plate sludge spreading, the inner wall of the annular sludge barrel 3 greatly expands the spreading area of ​​the sludge, so that the contact area between the sludge and the air is increased, thereby improving the sludge air-drying efficiency, so that the sludge drying efficiency is improved;

[0034] For some sludge with a large water content, the staff will increase the rotation speed of the first motor 14. The rotating first motor 14 will drive the sludge barrel 3 to rotate by rotating the driving roller 13. When the sludge barrel 3 increases its rotation speed, the free water in the sludge inside the sludge barrel 3 will flow out through the dewatering cloth 32 under the action of centrifugation, so that the free water in the sludge is quickly separated, and the sludge is quickly dehydrated. As the sludge barrel 3 rotates, the sludge at the upper position on the inner side of the sludge barrel 3 is dried first, and the inner side of the sludge barrel 3 is in circulation and in contact with the undried sludge at the lower position on the inner side of the sludge barrel 3. In this way, as the sludge barrel 3 rotates in a cycle, the sludge thickness on the inner wall of the sludge barrel 3 becomes larger and larger, and the sludge on the inner wall of the sludge barrel 3 becomes thicker and thicker. When the dewatering cloth 32 in the dewatering tank 31 is located in the lower half of the sludge barrel 3, the dewatering cloth 32 bulges toward the outside of the sludge barrel 3, and when the dewatering cloth 32 is located in the upper half of the sludge barrel 3, the dewatering cloth 32 with the sludge adhered to it will bulge toward the inside of the sludge barrel 3 under the action of gravity, so that during the back and forth movement of the dewatering cloth 32, the dried sludge on the dewatering cloth 32 located in the upper half of the sludge barrel 3 will fall off, and the dried sludge will eventually fall to the lower position of the inner side of the sludge barrel 3. Finally, after the sludge in the sludge barrel 3 is completely dried, the dried sludge in the sludge barrel 3 can be directly scraped out, and the staff can then pour out the wastewater in the collection box 2; the dried sludge will be processed in the next step;

[0035] The present invention spreads the sludge on the inner wall of the sludge barrel 3 and cooperates with the airflow passing through the front and rear of the sludge barrel 3 to increase the contact area between the sludge and the air, thereby improving the sludge drying efficiency. In addition, by increasing the rotation speed of the sludge barrel 3, the wastewater in the sludge on the inner wall of the sludge barrel 3 can be quickly thrown out, thereby further improving the sludge drying efficiency.

[0036] Embodiment 2: A bottom groove 33 is provided at the bottom wall position of the sludge barrel 3; the bottom groove 33 is rotatably sealed and connected to the chassis 4; the air vent 41 is provided on the chassis 4; the outer wall of the chassis 4 is fixedly connected to the output shaft of the second motor 42; the outer wall of the second motor 42 is fixedly connected to the upper surface of the box body 1; a sludge plate 6 is provided in contact with the inner wall of the sludge barrel 3; the sludge plate 6 is obliquely arranged on the inner side of the sludge barrel 3; one end of the sludge plate 6 extends to the opening of the sludge barrel 3, and the other end extends to the bottom groove 33 and is fixedly connected to the chassis 4.

[0037] In this embodiment, there are multiple sludge plates 6; the multiple sludge plates 6 are evenly distributed around the center of the sludge barrel 3; the ends of the multiple sludge plates 6 away from the chassis 4 are connected to the support ring 61; the support ring 61 is arranged close to the opening of the sludge barrel 3.

[0038] In this embodiment, an annular support groove 34 is provided on the inner wall of the sludge barrel 3 near the opening; the support ring 61 is rotatably sealed and connected in the support groove 34; the support ring 61 is adapted to the shape of the support groove 34.

[0039] In this embodiment, the inner diameter of the sludge barrel 3 is set to decrease as it approaches the bottom tank 33; the undried sludge in the sludge barrel 3 is gathered at a lower position on the inner side of the sludge barrel 3 and close to the opening.

[0040] In this embodiment, the end of the sludge plate 6 close to the opening of the sludge barrel 3 is rotatably connected to the support ring 61 through a support block 62; the end of the sludge plate 6 close to the bottom groove 33 is rotatably connected to the chassis 4 through a torsion spring 63; a stopper 64 is provided on one side of the sludge plate 6; the stopper 64 is fixedly connected to the chassis 4; the sludge plate 6 can be flipped unidirectionally as the sludge barrel 3 rotates.

[0041] During operation, the inner diameter of the sludge barrel 3 decreases as it approaches the bottom tank 33, but the slope of the sludge barrel 3 formed by the reduction in the inner diameter of the sludge barrel 3 is not very large, and the opening of the sludge barrel 3 is contracted toward the center, so that the sludge in the sludge barrel 3 will not flow out along the opening of the sludge barrel 3. As the sludge containing wastewater is poured into the inner side of the sludge barrel 3 along the opening of the sludge barrel 3, the sludge will gather at a position on the lower inner side of the sludge barrel 3 and close to the opening; then the first motor 14 will drive the driving roller 13 to rotate, and the driving roller 13 will drive the sludge barrel 3 to rotate counterclockwise from the front side perspective, and the sludge barrel 3 will rotate during the rotation. The undried sludge is covered on the dewatering cloth 32 on the inner wall of the sludge barrel 3. During the counterclockwise rotation of the sludge barrel 3, the second motor 42 will drive the chassis 4 to rotate counterclockwise. During the counterclockwise rotation of the chassis 4, the plurality of sludge plates 6 will be driven to revolve around the center of the chassis 4. The rotation speed of the sludge plates 6 driven by the chassis 4 is greater than the rotation speed of the sludge barrel 3. In this way, on the one hand, the speed at which the sludge barrel 3 generates centrifugal force is met, and on the other hand, the movement speed of the sludge plates 6 on the inner side of the sludge barrel 3 is not too fast. During the movement of the inner wall of the sludge barrel 3, the undried sludge in the sludge barrel 3 can be lifted up. During the process of the mud plate 6 moving from bottom to top, the undried sludge will flow along the inclined mud plate 6 toward the bottom plate 4, and the sludge will be dispersed under the action of the mud plate 6; in order to improve the strength of the mud plate 6, a support ring 61 is connected to the end of the mud plate 6 away from the bottom plate 4, so that the mud plate 6 is not easy to bend, thereby ensuring the use effect of the mud plate 6. In addition, since the support ring 61 is rotatably sealed and connected in the support groove 34, the setting of the support ring 61 will not interfere with and block the outflow and inflow of the sludge, so that the position of the inner wall of the sludge cylinder 3 near the opening is smoother; during the counterclockwise revolution of the mud plate 6 In the process of the sludge plate 6 passing through the undried sludge at the lower position of the inner side of the sludge barrel 3, the sludge plate 6 will lift the sludge at the lower position of the inner side of the sludge barrel 3. As the sludge plate 6 is lifted, the sludge plate 6 will overcome the torsion spring 63 and rotate. During the rotation process, the sludge plate 6 will spread the lifted sludge on the inner wall of the sludge barrel 3, so that the sludge at the lower position of the inner side of the sludge barrel 3 is fully spread out by the rotation of the sludge plate 6. After the sludge is spread out, it is prevented from gathering at the lower position of the inner side of the sludge barrel 3 to affect the drying efficiency. The spread sludge is dried faster, so that the sludge drying efficiency is further improved.

[0042] After the sludge in the sludge barrel 3 is dried, it will agglomerate, the first motor 14 will stop rotating, the second motor 42 will drive the chassis 4 to rotate clockwise, and the chassis 4 will drive the sludge plate 6 to revolve clockwise during the clockwise rotation. During the clockwise revolution, the sludge plate 6 will contact the dried sludge on the inner wall of the sludge barrel 3, and the sludge plate 6 will flip back to its original position under the obstruction of the sludge. After flipping back, the sludge plate 6 will contact the dewatering cloth 32, and the sludge plate 6 cannot continue to rotate under the support of the block 64, that is, the sludge plate 6 can only rotate in one direction, and the sludge plate 6 pushes the inner wall of the sludge barrel 3 under the support of the block 64. sludge, thereby causing the sludge on the dewatering cloth 32 on the inner wall of the sludge barrel 3 to fall down under the push of the sludge plate 6, and the dried sludge will fall to the lower inner side of the sludge barrel 3 under the action of gravity. Since the inner diameter of the sludge barrel 3 decreases as it approaches the chassis 4, the dried sludge will gather at the lower inner side of the sludge barrel 3 and close to the opening. When the sludge plate 6 passes through the lower inner side of the sludge barrel 3, the sludge plate 6 will lift the agglomerated sludge. During the movement of the sludge plate 6 from bottom to top, the sludge lifted by the sludge plate 6 will move along the inclined sludge plate 6 toward the opening of the sludge barrel 3 and be discharged.

[0043] Embodiment 3: The upper part of the arch cover 5 is half-sleeve-shaped; the inner wall of the upper part of the arch cover 5 is in contact with a ring-shaped limit strip 7; there are two limit strips 7; one of the limit strips 7 is close to the outer side of the sludge barrel 3, and the other limit strip 7 is close to the rear side of the sludge barrel 3; the limit strip 7 is fixedly connected to the outer wall of the sludge barrel 3; and the plurality of dehydration cloths 32 are located between the two limit strips 7.

[0044] In this embodiment, the outer wall of the sludge barrel 3 is evenly fixed to the push bar 8; the edge of the push bar 8 away from the sludge barrel 3 can contact the inner wall of the upper half of the arch cover 5; the push bar 8 is long and strip-shaped; the push bar 8 is located between two limit bars 7, and the length direction of the push bar 8 is the same as the axial direction of the sludge barrel 3; the end of the push bar 8 is fixed to the limit bar 7.

[0045] In this embodiment, there are two push bars 8; the push bar 8 and the limit bar 7 are in active sealing contact with the inner wall of the arch cover 5; a slot 51 is horizontally penetrated at the junction of the upper and lower parts of the arch cover 5; the insertion bar 9 is slidably and sealingly connected in the slot 51; a guide surface 91 is provided at the lower position of the insertion bar 9 close to one end of the sludge barrel 3; the end of the insertion bar 9 away from the sludge barrel 3 is connected to the outer wall of the arch cover 5 by an elastic rope 92; the push bar 8 can contact the guide surface 91 when the sludge barrel 3 rotates.

[0046] During operation, in order to improve the transmission effect of the driving roller 13 on the outer wall of the sludge barrel 3, an outer tooth ring can be provided on the outer wall of the sludge barrel 3, and a gear can be provided on the outer wall of the driving roller 13. Through the gear meshing transmission, the sludge barrel 3 can rotate more stably. During the rotation of the sludge barrel 3, the limit strip 7 on the outer wall can be driven to rotate. The limit strip 7 is in active contact with the inner side of the upper half of the arch cover 5, so that the transmission of the sludge barrel 3 is more stable. During the rotation of the sludge barrel 3, the sewage on the inner side of the dewatering cloth 32 can be thrown out, and the sewage will fall on the inner wall of the arch cover 5. As the outer wall of the sludge barrel 3 is fixedly connected to the push strip 7, the sewage will fall on the inner wall of the arch cover 5. 8. The setting of the push strip 8 can quickly push away the sewage on the inner wall of the arch cover 5, so that the sewage finally flows into the collection box 2 along the inner wall of the arch cover 5 for collection; during the counterclockwise rotation of the sludge barrel 3, the push strip 8 on the outer wall will be driven to circulate and contact with the guide surface 91 on the insertion strip 9. The insertion strip 9 overcomes the elastic rope 92 and moves away from the sludge barrel 3 under the push of the push strip 8. After the push strip 8 passes over the insertion strip 9, the insertion strip 9 is reset under the pull of the elastic rope 92. The insertion strip 9 will be against the outer surface of the sludge barrel 3 and the outer surface of the dewatering cloth 32. The insertion strip 9 contacts the limiting strip 7, so that the push strip 8 passes over the insertion strip. A negative pressure zone will be formed behind the strip 9, and the space of the negative pressure zone expands to form negative pressure. The span of the negative pressure zone is the upper half of the entire arch cover 5, and the negative pressure zone corresponds to the upper half of the sludge barrel 3, so that the sludge on the inner wall of the upper half of the sludge barrel 3 is subjected to the negative pressure of the negative pressure zone while being subjected to the centrifugal force. On the one hand, this makes it easier to throw out the sewage, and on the other hand, it makes it easier for the sludge to adhere to the inner wall of the upper half of the sludge barrel 3, thereby reducing the probability of the undried sludge on the inner wall of the upper half of the sludge barrel 3 falling off, so that the inner wall of the sludge barrel 3 can be covered with sludge, ensuring the drying effect of the sludge. rate; since there are at least two push bars 8, all inner wall positions of the sludge barrel 3 can have negative pressure adsorption force when passing through the negative pressure zone, so that the sludge can be spread out and air-dried more stably, and the sludge originally on the inner wall of the lower half of the sludge barrel 3 is more stable under the action of gravity; the movable sealing contact in the present invention can be provided with some wear-resistant materials, or rolling parts can be directly provided to reduce wear. The negative pressure zone of the present invention does not require absolute sealing, but only needs to form a negative pressure effect, so that the sludge can be better attached to the inner wall of the upper half of the sludge barrel 3.
