AI Technical Summary
Existing sludge recovery devices are prone to jamming the crushing rollers during the crushing process due to the excessive size of the sludge blocks, resulting in a decrease in crushing efficiency. Furthermore, the powdered sludge is prone to caking at the discharge port, causing blockages.
The system employs a graded crushing structure, using a combination of crushing rollers and grinding rollers to initially break down sludge blocks and reduce their volume. The grinding rollers then further crush the sludge. The design, combined with movable plates and rubber plates, prevents the powdery sludge from caking and ensures smooth discharge.
This effectively avoids the impact of sludge volume on crushing efficiency and prevents powdered sludge from caking at the discharge port, ensuring smooth sludge discharge and improving overall processing efficiency.

[0015] Compared with the prior art, this utility model provides a recycling device for urban sludge treatment, which has the following beneficial effects:
[0016] 1. This utility model utilizes a configuration of crushing rollers. Two crushing rollers are fixedly installed in a group on the front and rear sides inside the cavity of the limiting tube, with the gears on the left end of the same group of crushing rollers meshing with each other. Crushing rollers are symmetrically installed directly below the bottom of the guide plate, with the gears on the left end of the crushing rollers meshing with each other. The crushing rollers and crushing rollers are rotatably connected to the limiting tube via bearings. When sludge blocks enter the limiting tube through the feed inlet, the limiting plates on both sides of the feed inlet guide the sludge blocks to fall directly above the guide blocks. After impacting the guide blocks, the sludge blocks are diverted and guided to the top of the two sets of crushing rollers, where they are crushed by the crushing rollers. The mud lumps undergo initial crushing. After passing through the crushing rollers, the mud lumps move above the crushing rollers under the guidance of the guide plate. The crushing rollers then further crush the mud lumps. The speed reducer increases the output torque, allowing the crushing rollers and crushing rollers to rotate at low speed and high torque. The drive motor drives the speed reducer. This method, through staged crushing, initially crushes the mud lumps before they are further crushed, reducing their volume. This allows the mud lumps to be positioned in small blocks above the crushing rollers and then crushed, preventing the crushing efficiency from being affected by excessively large mud lumps.
[0017] 2. This utility model utilizes a movable plate located inside the discharge hopper. The movable plate has L-shaped connecting rods on its bottom left and right sides, which are fixedly connected to the movable end of a connecting piston. The connecting piston is fixedly connected to the discharge hopper via a fixed block. When the connecting piston extends, it moves the movable plate downwards; when it retracts, it moves the movable plate upwards. The connecting piston causes the movable plate to move the rubber plate up and down reciprocally, moving the rubber plate downwards to the bottom of the discharge hopper. Because the width of the rubber plate is greater than the width of the bottom opening of the discharge hopper, it will bend and deform as it moves upwards past the bottom of the discharge hopper, and then return to its original shape inside the discharge hopper after passing the bottom. This breaks down the compaction of the powdery sludge inside the discharge hopper, facilitating sludge discharge. This method prevents the powdery sludge from compacting inside the discharge hopper, thus hindering its discharge. Attached Figure Description

[0026] Please see Figure 1 - Figure 4In this embodiment, a recycling device for urban sludge treatment includes: a support frame 1; a limiting tube 11 is fixedly installed on one side of the support frame 1; an inlet 12 is fixedly installed above the limiting tube 11; a limiting plate 13 is fixedly installed inside the inlet 12; a limiting block 14 and a guide block 15 are fixedly installed inside the limiting tube 11; a guide plate 16 is fixedly installed at the center of the limiting tube 11; a crushing roller 17 and a pulverizing roller 18 are movably installed inside the limiting tube 11; a gear 19 is fixedly installed at the left end of the crushing roller 17 and the pulverizing roller 18; and the crushing roller 17 and the pulverizing roller 18... Bearings 110 are installed on both sides. A reducer 111 is fixedly installed on the right end of the crushing roller 17 and the crushing roller 18. A drive motor 112 is fixedly installed on the right side of the reducer 111. A bracket 113 is fixedly installed below the drive motor 112. A discharge hopper 114 is fixedly installed at the lower end of the limit tube 11. A fixing block 115 is fixedly installed on the outside of the discharge hopper 114. A connecting piston 116 is fixedly installed below the fixing block 115. A movable plate 117 is fixedly installed at the bottom end of the connecting piston 116. Rubber plates 118 are fixedly installed on the front and rear sides of the movable plate 117.
[0027] The support frame 1 is symmetrically installed on both the front and rear sides of the limiting tube 11 with the center of the limiting tube 11 as the reference. The limiting tube 11 is a rectangular pipe structure. The limiting plate 13 is mirror-symmetrically installed on both the front and rear sides of the inlet 12 cavity. The limiting block 14 is mirror-symmetrically installed on both the front and rear sides of the top of the limiting tube 11 cavity. The guide block 15 is fixedly installed at the center of the top of the limiting tube 11 cavity, and the guide block 15 has a sloping structure on the left and right sides above it. The spacing between the outer teeth of the crushing roller 17 is greater than the spacing between the teeth of the crushing roller 18. The two crushing rollers 17 are fixedly installed in a group on both the front and rear sides inside the cavity of the limiting tube 11, and the gears 19 on the left end of the same group of crushing rollers 17 mesh with each other. The crushing rollers 18 are symmetrically installed directly below the bottom of the guide plate 16. The gears 19 on the left end of 18 mesh with each other. The crushing roller 17 and the crushing roller 18 are rotatably connected to the limiting tube 11 through the bearing 110. The inner cavity of the discharge hopper 114 has an inverted trapezoidal structure. The fixing block 115 is mirror-symmetrically installed on the left and right sides of the discharge hopper 114 with the center of the discharge hopper 114 as the reference. The connecting piston 116 is fixedly connected to the discharge hopper 114 through the fixing block 115. The movable plate 117 is located inside the discharge hopper 114, and the bottom left and right sides of the movable plate 117 are provided with "L"-shaped connecting rods fixedly connected to the movable end of the connecting piston 116. The rubber plate 118 is symmetrical front and back and is vertically and equidistantly installed on the front and back sides of the movable plate 117. The width of the rubber plate 118 is greater than the width of the opening structure at the bottom of the discharge hopper 114.
[0028] Specifically, the support frame 1 can limit the height of the limiting tube 11 to increase the falling stroke of the sludge block. The limiting tube 11 can limit the position of the crushing roller 17 and the crushing roller 18. When the sludge block enters the limiting tube 11 through the feed inlet 12, the limiting plates 13 on both sides of the feed inlet 12 will guide the sludge block to fall from directly above the guide block 15. After hitting the guide block 15, the sludge block will be diverted by the guide block 15 and guided to the top of the two sets of crushing rollers 17. The crushing rollers 17 will perform preliminary crushing of the sludge block. After passing through the crushing rollers 17, the sludge block will move to the top of the crushing roller 18 under the guidance of the guide plate 16. The crushing roller 18 will then crush the crushed sludge block. The gear 19 can facilitate the opposite rotation direction of the crushing rollers 17 and the crushing roller 18 in the same group. The reducer 111 can increase the output torque so that the crushing rollers 17 and the crushing roller 18 can rotate at low speed and high torque. The drive motor 112 can drive the reducer 111. The bracket 113 can reduce the speed of the reducer. The machine 111 and drive motor 112 provide support. The inner cavity of the discharge hopper 114 has an inverted trapezoidal structure. After the sludge blocks are crushed, they will be discharged from directly below the discharge hopper 114 under the guidance of the discharge hopper 114, so as to facilitate the collection of the crushed sludge blocks. The fixing block 115 restricts the position of the top of the connecting piston 116. When the connecting piston 116 extends, it will drive the movable plate 117 to move downward. When it retracts, it will drive the movable plate 117 to move upward. The plug 116 causes the movable plate 117 to drive the rubber plate 118 to move up and down reciprocally, so that the rubber plate 118 moves downward to the bottom of the discharge hopper 114. Since the width of the rubber plate 118 is greater than the width of the bottom opening of the discharge hopper 114, the rubber plate 118 will bend and deform when it moves upward through the bottom of the discharge hopper 114, and will return to its original shape inside the discharge hopper 114 after passing through the bottom of the discharge hopper 114, thereby breaking the compacted state of the powdery sludge inside the discharge hopper 114, so as to facilitate the discharge of sludge.
[0029] In use, two crushing rollers 17 are fixedly installed in pairs inside the cavity of the limiting tube 11 on both the front and rear sides, and the gears 19 on the left end of the same crushing roller 17 mesh with each other. The pulverizing rollers 18 are symmetrically installed directly below the bottom of the guide plate 16, and the gears 19 on the left end of the pulverizing rollers 18 mesh with each other. The crushing rollers 17 and pulverizing rollers 18 are rotatably connected to the limiting tube 11 via bearings 110. When the sludge blocks enter the limiting tube 11 through the feed inlet 12, the limiting plates 13 on both the front and rear sides of the feed inlet 12 will guide the sludge blocks to fall directly above the guide block 15. After impacting the guide block 15, the sludge blocks will... The sludge is diverted by guide block 15 and guided above the front and rear sets of crushing rollers 17. The crushing rollers 17 perform initial crushing of the sludge blocks. After passing through the crushing rollers 17, the sludge blocks move under the guidance of guide plate 16 to above the crushing rollers 18, where the crushing rollers 18 further crush the sludge blocks. Reducer 111 increases the output torque, allowing the crushing rollers 17 and 18 to rotate at low speed and high torque. Drive motor 112 drives reducer 111. This method, through staged crushing, initially crushes the sludge blocks using crushing rollers 17 before further crushing, reducing the amount of sludge. The volume of the mud lumps allows them to be positioned in small blocks above the crushing roller 18 for crushing, preventing excessively large mud lumps from affecting crushing efficiency. The movable plate 117 is located inside the discharge hopper 114, and its bottom left and right sides are equipped with "L"-shaped connecting rods fixedly connected to the movable end of the connecting piston 116. The connecting piston 116 is fixedly connected to the discharge hopper 114 via a fixed block 115. When the connecting piston 116 extends, it drives the movable plate 117 downwards; when it retracts, it drives the movable plate 117 upwards. The piston 116 causes the movable plate 117 to drive the rubber plate 118 to move up and down reciprocally, so that the rubber plate 118 moves downward to the bottom of the discharge hopper 114. Since the width of the rubber plate 118 is greater than the width of the bottom opening of the discharge hopper 114, the rubber plate 118 will bend and deform when it moves upward through the bottom of the discharge hopper 114, and will return to its original shape inside the discharge hopper 114 after passing through the bottom of the discharge hopper 114, thereby breaking the caking state of the powdery sludge inside the discharge hopper 114, so as to facilitate the discharge of sludge. This method can prevent the powdery sludge from caking inside the discharge hopper 114, which would affect the discharge of powdery sludge.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
