Description

Technical Field

[0001] This invention belongs to the field of sludge treatment technology, specifically relating to an electroplating sludge reduction treatment device. Background Technology

[0002] Electroplating sludge reduction treatment equipment is used to treat sludge generated in the electroplating industry. Through an integrated treatment process, it reduces the volume and weight of sludge to achieve waste reduction and environmentally friendly disposal. The entire system is monitored by an automatic control unit to ensure stable and efficient treatment. This equipment is suitable for electroplating wastewater treatment facilities, metal processing enterprises, and other places. It can reduce sludge disposal costs, reduce environmental risks, and promote resource utilization such as building material production or safe landfill.

[0003] Existing low-temperature drying devices for electroplating sludge use a continuously operating planar mesh belt to transport sludge strips in the drying section. In this structure, the mesh belt is used for static transport, and the sludge strips are in a fixed position. This results in the hot air from the bottom being blocked by the tightly packed sludge strips, leading to uneven airflow distribution and the potential for localized airflow short-circuiting between the strips, reducing overall heat exchange efficiency. During the drying process, surface moisture evaporates first, forming a dense, hard shell. This shell hinders further outward migration of internal moisture and inward penetration of hot air, causing a significant decrease in drying rate in the later stages and increased energy consumption. Simultaneously, wet sludge strips easily adhere to the mesh belt surface, and dried debris may clog the mesh after drying. Long-term operation reduces the mesh belt's permeability, requiring shutdown and cleaning. Existing devices lack mechanical structures that actively intervene in the physical state of the sludge during the drying process, making it impossible to break through the surface hard shell and optimize the air permeability channels, thus limiting further improvements in drying efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an electroplating sludge reduction treatment device to solve the problems mentioned in the background art of existing treatment devices, such as sludge accumulation due to the stationary mesh belt, which hinders hot air penetration and causes surface crusting, resulting in low internal drying efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electroplating sludge reduction treatment device, the device comprising an outer casing, a drying mechanism, and an efficiency-enhancing mechanism;

[0006] The drying mechanism includes a conveying section and a drying section. The conveying section is placed inside the outer casing, while the exhaust position of the drying section is directly below the conveying section. High-temperature gas is sprayed out by the drying section to dry the soil strips placed on the conveying section.

[0007] The enhancement mechanism includes a lifting component and a striking component;

[0008] The lifting component is located inside the transmission section, and the lifting component swings as the transmission section rotates.

[0009] The striking component is located above the mud strip being conveyed by the transmission section. Under the swing of the lifting component, the striking component performs a vertical reciprocating motion. The striking component has at least two alternating striking points, thereby achieving alternating striking and maximizing the use of the lifting component's power to achieve efficient striking.

[0010] As a preferred technical solution of the present invention, the transmission unit includes an upper conveyor belt and a lower conveyor belt arranged at an interval; the vertical projection of the unloading end of the upper conveyor belt is inside the loading end of the lower conveyor belt, thereby ensuring that the mud strips falling from the upper conveyor belt can be caught by the lower conveyor belt and subsequently dried; a transmission shaft is installed at one end of the upper and lower conveyor belts, and a servo motor is installed at the end of the transmission shaft; an arc-shaped groove is formed on the surface of the transmission shaft;

[0011] Two sets of lifting components are provided and placed inside the upper and lower conveyor belts respectively. The striking component is located above the lower conveyor belt and does not contact the upper conveyor belt. The function of the striking component is to slightly squeeze the clay strips that are dry on the outside but not dry on the inside, so that cracks are created on the surface of the clay strips, which facilitates the subsequent entry of hot air for drying. Since the overall dryness of the clay strips located on the upper conveyor belt is not sufficient to dry the inside, no striking component is added at the position of the upper conveyor belt.

[0012] As a preferred technical solution of the present invention, the lifting assembly includes a main camshaft, a connecting plate, a counterweight, and an auxiliary camshaft.

[0013] The main camshaft is inclined towards the transmission shaft, and its top end is positioned within the arc-shaped groove. During transmission shaft rotation, when the main camshaft is pushed out of the arc-shaped groove, the transmission shaft presses against it, causing the top of the main camshaft to rotate upwards. The main camshaft, through the connecting plate, lifts the tops of all auxiliary camshafts, and the connecting plate and counterweight also rise synchronously. The bottoms of the auxiliary camshafts rotate around the shaft column. At this time, the main and auxiliary camshafts press against the corresponding upper and lower conveyor belts. When the arc-shaped groove rotates back to the position of the main camshaft, it remains in an inclined state after being lifted. The main camshaft and auxiliary camshaft rotate in opposite directions. Combined with the gravity of the counterweight, this further increases the speed at which the main camshaft returns to its original position. At this time, the upper and lower conveyor belts are no longer pressed together and return to their original positions. This achieves high-frequency vibration of the upper and lower conveyor belts, which knocks them upward and returns them to their original positions downward. This method can not only vibrate out the sludge stuck in the mesh of the upper and lower conveyor belts to prevent blockage, but also lift up the accumulated sludge strips in the sludge lifting process, separating them from the upper and lower conveyor belts. This facilitates the upward discharge of gas from the drying section below and improves the drying effect.

[0014] Two connecting plates are provided and are symmetrically arranged on both sides of the main camshaft. A connecting shaft is also fixed on the inner side of the connecting plates.

[0015] Multiple counterweights are provided and are all fixed on the lower end face of the connecting plate. A lifting column is also fixed on the outer surface of the counterweight near the feeding end of the lower conveyor belt. The purpose of setting the counterweights is to provide gravity for the main camshaft and the auxiliary camshaft so that they can quickly fall back to their original positions.

[0016] Multiple auxiliary camshafts are provided and placed inside the two connecting plates. The top end face of the auxiliary camshaft has a hole for the insertion of the connecting shaft. The connecting plates drive all the auxiliary camshafts to move synchronously.

[0017] As a preferred technical solution of the present invention, the main camshaft and the auxiliary camshaft have the same tilt angle, and a shaft post is fixed at the bottom of the end face of the auxiliary camshaft. The shaft post is rotatably installed on the inner wall of the outer housing. The top of the end face of the main camshaft is also movably penetrated by the connecting shaft. Therefore, when the main camshaft rotates, it will push the connecting shaft, which will drive the connecting plate through the connecting shaft, and then drive all the connecting shafts through the connecting plate to push the auxiliary camshaft to swing.

[0018] As a preferred technical solution of the present invention, the striking component includes a first pressing block and a second pressing block;

[0019] The first and second pressing blocks are arranged side by side above the lower conveyor belt. A connecting rod assembly is provided between the first and second pressing blocks, and a lifting plate is fixed at the end of the second pressing block. The bottom of the lifting plate overlaps the lifting column. Therefore, when the connecting plate and counterweight are raised or lowered, the lifting column will be raised or lowered. The raising or lowering of the lifting column will drive the lifting plate to rise. Finally, the lifting plate will drive the second pressing block to rise or lower. When the second pressing block rises or lowers, it will knock the mud strips on the lower conveyor belt, causing gaps to appear on the surface of the mud strips. Finally, hot air can enter the gaps to achieve efficient drying.

[0020] As a preferred technical solution of the present invention, both ends of the top of the first pressing block and the second pressing block are fixedly provided with connecting ears, and end posts are fixedly provided on the inner side of the connecting ears.

[0021] The linkage assembly includes a connecting rod and a central shaft;

[0022] The connecting rod has its two ends sleeved on the end posts, while one end of the central shaft movably passes through the middle of the connecting rod, and the other end is fixed to the inner wall of the outer casing. When the second pressure block is lifted, it will drive one end of the connecting rod to lift, while the other end of the connecting rod will descend, driving the first pressure block to descend as well. The descending first pressure block will then strike the clay strip, preventing some un-striked clay strips from being directly transmitted during the lifting of the second pressure block. At the same time, the function of striking twice is achieved through a single lifting and lowering. To prevent the connection from loosening, a pin or other structure can be used to sleeve the central shaft and end posts.

[0023] As a preferred technical solution of the present invention, the inner wall of the outer casing is provided with a movable groove for the lifting plate to move up and down, and the lifting column is also placed in the movable groove;

[0024] The lifting column travels with a width less than or equal to its width within the moving groove during lifting and lowering. This is because the overall movement trajectory of the lifting column during lifting and lowering is arc-shaped, so its lifting height is less than its travel trajectory. This design also ensures that the first and second pressing blocks descend to a lower height, preventing excessive compression of the mud strips.

[0025] As a preferred technical solution of the present invention, the top surface of the lifting plate is higher than the plane where the connecting ear is located, and during the lifting process, the bottom surface of the lifting plate is located inside the lower conveyor belt. By setting the height of the second pressure block, it is ensured that the moving groove of the mud strip is always blocked by the lifting plate during the lifting process, so as to prevent the mud strip from entering the moving groove.

[0026] As a preferred technical solution of the present invention, the drying section includes a hot air drying assembly, which is installed on the outside of the outer casing. A hot air pipe is connected to the side of the hot air drying assembly and extends to the bottom of the outer casing. A hot air furnace assembly is installed inside the hot air drying assembly to generate high-temperature gas to dry the clay strips. A condensation circulation assembly is also installed on the top of the hot air drying assembly. An exhaust port connected to the condensation circulation assembly is opened inside the outer casing. The condensation circulation assembly cools and condenses the discharged medium-temperature and medium-humidity gas and discharges the condensate. The drainage pipe is not shown in the figure. Since this structure and principle are existing technologies, they will not be described in detail here.

[0027] As a preferred technical solution of the present invention, a feed inlet is provided at the top of one end of the outer casing. At least two strip cutters are provided in the feed inlet, and servo motors are installed at the ends of the two strip cutters. The servo motors drive the strip cutters to rotate and cut the mud blocks poured in from the feed inlet into strips, thereby reducing the volume of the mud blocks and improving the drying efficiency. A discharge bin is also provided directly below the feed inlet. The discharge bin is located at the discharge end of the lower conveyor belt. In order to discharge the dried mud strips in the discharge bin, a spiral conveyor shaft can be provided in the discharge bin to realize automatic material feeding.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] In this invention, a lifting component is designed that enables the conveyor belt to generate periodic horizontal micro-vibration. This not only effectively prevents wet sludge from sticking to the conveyor belt, but also makes the upper sludge strips tend to be loosely arranged and lifted by vibration, thereby expanding the physical gap between the sludge strips, creating a smoother flow channel for hot air, promoting uniform airflow distribution, and enhancing heat and mass transfer.

[0030] The designed tapping component operates synchronously with the vibration gap of the conveyor belt, performing controlled elastic tapping on the surface of the passing sludge strips. This causes uniform micro-cracks to form on the hardened shell of the sludge strips during the mid-drying process. These micro-cracks provide a physical path for hot air to penetrate into the sludge, significantly increasing the evaporation area and breaking down the drying resistance from the surface inwards, thereby accelerating the removal of internal moisture. Through the design of this invention, the drying rate and energy efficiency are improved without stopping the machine or adding an additional heat source. Attached Figure Description

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Please see Figures 1 to 8 The present invention provides a technical solution: an electroplating sludge reduction treatment device, the treatment device including an outer casing 100, a drying mechanism, and an efficiency-enhancing mechanism;

[0055] The drying mechanism includes a conveying section and a drying section. The conveying section is placed inside the outer casing 100, while the exhaust position of the drying section is directly below the conveying section. High-temperature gas is sprayed out by the drying section to dry the soil strips placed on the conveying section.

[0056] The enhancement mechanism includes lifting component 200 and striking component 300;

[0057] The lifting component 200 is located inside the transmission section, and the lifting component 200 swings under the rotation of the transmission section.

[0058] The striking component 300 is located above the mud strip conveyed by the transmission section. Under the swing of the lifting component 200, the striking component 300 performs a vertical reciprocating motion of lifting and lowering. The striking component 300 has at least two alternating striking points, thereby realizing alternating striking and making greater use of the power of the lifting component 200 to achieve the purpose of efficient striking.

[0059] In this embodiment, refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 The transmission section includes an upper conveyor belt 106 and a lower conveyor belt 107 spaced apart vertically. The vertical projection of the unloading end of the upper conveyor belt 106 is inside the loading end of the lower conveyor belt 107, thereby ensuring that the mud strips falling from the upper conveyor belt 106 can be caught by the lower conveyor belt 107 for subsequent drying. A transmission shaft 108 is installed at one end inside both the upper conveyor belt 106 and the lower conveyor belt 107. A servo motor is installed at the end of the transmission shaft 108. The servo motor is not shown, but its position is... Figure 2 As shown in the figure, the transmission shaft 108 is driven to rotate by a servo motor; the surface of the transmission shaft 108 is provided with an arc-shaped groove 108a;

[0060] Two sets of lifting components 200 are provided and are respectively placed inside the upper conveyor belt 106 and the lower conveyor belt 107. The striking component 300 is located above the lower conveyor belt 107. The striking component 300 does not contact the upper conveyor belt 106. The function of the striking component 300 is to slightly squeeze the clay strips that are dry on the outside but not dry on the inside, so that cracks are created on the surface of the clay strips, which facilitates the subsequent hot air to enter the interior for drying. The clay strips located at the upper conveyor belt 106 are not dry enough to meet the requirements for drying the interior, so the striking component 300 is not added at the position of the upper conveyor belt 106.

[0061] In this embodiment, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 The lifting assembly 200 includes a main camshaft 201, a connecting plate 202, a counterweight 203, and an auxiliary camshaft 204.

[0062] The main camshaft 201 is inclined toward the transmission shaft 108, and the top end of the main camshaft 201 is placed in the arc-shaped groove 108a. In the figure, the main camshaft 201 is in an unlifted state. As the transmission shaft 108 rotates, when the main camshaft 201 is pushed out of the arc-shaped groove 108a, the transmission shaft 108 squeezes the main camshaft 201, causing the top end of the main camshaft 201 to rotate upwards. The main camshaft 201, through the connecting plate 202, connects all the auxiliary cams. The top of shaft 204 is raised, and connecting plate 202 and counterweight 203 also rise synchronously. The bottom of auxiliary camshaft 204 rotates around shaft column 204a. It is worth noting that the maximum angle of the raised main camshaft 201 is an acute angle, which is determined according to the angle at which the lower conveyor belt 107 needs to be raised. It cannot be a right angle or an obtuse angle to avoid the main camshaft 201 being raised too much, causing it to puncture the upper conveyor belt 106 and the lower conveyor belt 107, and preventing it from returning to its original position. At this time, the main camshaft 201 and the auxiliary camshaft 204 squeeze the upper conveyor belt 106 and the lower conveyor belt 107 at the corresponding positions. When the arc groove 108a rotates to the position of the main camshaft 201 again, the main camshaft 201 and the auxiliary camshaft 204, which are still in an inclined state after being lifted, rotate in the opposite direction. At the same time, with the gravity of the counterweight 203, the speed of the main camshaft 201 returning to its original position is further increased. At this time, the upper conveyor belt 106 and the lower conveyor belt 107 are no longer pressed and are returned to their original positions, thereby realizing the high-frequency vibration of the upper conveyor belt 106 and the lower conveyor belt 107 being knocked upward and returned to their original positions downward. This method can not only vibrate out the sludge stuck in the mesh of the upper conveyor belt 106 and the lower conveyor belt 107 to prevent blockage, but also lift the accumulated sludge strips in the lifting process and separate them from the upper conveyor belt 106 and the lower conveyor belt 107, so as to facilitate the upward discharge of gas from the drying section below and improve the drying effect.

[0063] Two connecting plates 202 are provided and are symmetrically arranged on both sides of the main camshaft 201. A connecting shaft 202a is also fixed on the inner side of the connecting plates 202.

[0064] Multiple counterweights 203 are provided and are all fixed on the lower end face of the connecting plate 202. A lifting column 203a is also fixed on the outer surface of the counterweight 203 near the feeding end of the lower conveyor belt 107. The purpose of setting the counterweights 203 is to provide gravity for the main camshaft 201 and the auxiliary camshaft 204 so that they can quickly fall back to their original positions.

[0065] Multiple auxiliary camshafts 204 are provided and placed inside the two connecting plates 202. The top end face of the auxiliary camshaft 204 is provided with a hole for the connecting shaft 202a to be inserted. All the auxiliary camshafts 204 are driven to move synchronously through the connecting plates 202.

[0066] In this embodiment, refer to Figure 5 , Figure 6 The main camshaft 201 and the auxiliary camshaft 204 have the same tilt angle, and a shaft post 204a is fixed at the bottom of the end face of the auxiliary camshaft 204. The shaft post 204a is rotatably mounted on the inner wall of the outer housing 100. The top of the end face of the main camshaft 201 is also movably penetrated by the connecting shaft 202a. Therefore, when the main camshaft 201 rotates, it will push the connecting shaft 202a, which will drive the connecting plate 202. Then, the connecting plate 202 will drive all the connecting shafts 202a to push the auxiliary camshaft 204 to swing.

[0067] In this embodiment, refer to Figure 5 , Figure 7 , Figure 8 The striking component 300 includes a first pressing block 301 and a second pressing block 302;

[0068] The first pressing block 301 and the second pressing block 302 are arranged side by side above the lower conveyor belt 107. A connecting rod assembly is provided between the first pressing block 301 and the second pressing block 302. A lifting plate 302a is fixed at the end of the second pressing block 302. The bottom of the lifting plate 302a overlaps the lifting column 203a. Therefore, when the connecting plate 202 and the counterweight 203 are raised or lowered, the lifting column 203a will be raised or lowered. The raising or lowering of the lifting column 203a will drive the lifting plate 302a to rise. Finally, the lifting plate 302a will drive the second pressing block 302 to rise or lower. When the second pressing block 302 is raised or lowered, it will knock the mud strips on the lower conveyor belt 107, so that gaps are created on the surface of the mud strips. Finally, hot air can enter the gaps to achieve efficient drying.

[0069] In this embodiment, refer to Figure 8 Both ends of the top of the first pressure block 301 and the second pressure block 302 are fixed with connecting ears 303, and end posts 306 are fixed on the inner side of the connecting ears 303.

[0070] The linkage assembly includes a link 304 and a central shaft 305;

[0071] The connecting rod 304 has both ends sleeved on the end post 306, while one end of the central shaft 305 is movably inserted through the middle of the connecting rod 304, and the other end is fixed to the inner wall of the outer housing 100. When the second pressure block 302 is lifted, the second pressure block 302 will drive one end of the connecting rod 304 to lift, while the other end of the connecting rod 304 will descend, and drive the first pressure block 301 to descend. The descending first pressure block 301 will strike the clay strip, preventing some clay strips that have not been struck from being directly transmitted during the lifting of the second pressure block 302. At the same time, the function of striking twice is achieved through a single lifting. In order to prevent the connection from loosening, a structure such as a pin can be set at the position of the central shaft 305 and the end post 306.

[0072] In this embodiment, refer to Figure 8 The inner wall of the outer casing 100 is provided with a movable groove 100a for lifting the lifting plate 302a, and the lifting column 203a is also placed in the movable groove 100a.

[0073] Among them, the travel width of the lifting column 203a during lifting and lowering is less than or equal to the width of its own movement within the moving groove 100a. Because the overall movement trajectory of the lifting column 203a during the lifting and lowering process is arc-shaped, its lifting height is less than its travel trajectory. This design can also ensure that the first pressing block 301 and the second pressing block 302 fall to a low height, so as not to cause excessive compression of the mud strip.

[0074] In this embodiment, refer to Figure 8 The top surface of the lifting plate 302a is higher than the plane where the connecting ear 303 is located. During the lifting process, the bottom surface of the lifting plate 302a is located inside the lower conveyor belt 107. By setting the height of the second pressure block 302, it is ensured that the moving groove 100a of the mud strip is always blocked by the lifting plate 302a during the lifting process, so as to prevent the mud strip from entering the moving groove 100a.

[0075] In this embodiment, refer to Figure 1 , Figure 2 The drying section includes a hot air drying assembly 104, which is installed outside the outer casing 100. A hot air pipe 104a, which runs through the side of the hot air drying assembly 104 and extends to the bottom of the outer casing 100, is connected to the side of the hot air drying assembly 104. A hot air furnace assembly is installed inside the hot air drying assembly 104 to generate high-temperature gas to dry the clay strips. A condensation circulation assembly 103 is also installed on the top of the hot air drying assembly 104. An exhaust port connected to the condensation circulation assembly 103 is opened inside the outer casing 100. The condensation circulation assembly 103 cools and condenses the discharged medium-temperature and medium-humidity gas and discharges the condensate. The drainage pipe is not shown in the figure. Since this structure and principle are existing technologies, they will not be described in detail here.

[0076] In this embodiment, a feed inlet 101 is provided at the top of one end of the outer casing 100. At least two strip cutters 102 are provided inside the feed inlet 101. A servo motor is installed at the end of each of the two strip cutters 102. The servo motor drives the strip cutter 102 to rotate, cutting the mud blocks poured in from the feed inlet 101 into strips, reducing the volume of the mud blocks and improving the drying efficiency. A discharge bin 105 is also provided directly below the feed inlet 101. The discharge bin 105 is located at the discharge end of the lower conveyor belt 107. In order to discharge the dried mud strips in the discharge bin 105, a spiral conveyor shaft can be provided in the discharge bin 105 to realize automatic material feeding.

[0077] The working principle of the processing device is explained below:

[0078] First, soil with a moisture content of approximately 75% is poured into the feed inlet 101. Then, the slitter 102, driven by a servo motor, rotates and cuts the sludge into strips, which then fall onto the upper conveyor belt 106. At this time, the transmission shaft 108, driven by the servo motor, rotates and periodically pushes the main camshaft 201 through the arc-shaped groove 108a. This causes the main camshaft 201 to drive the connecting plate 202 and the auxiliary camshaft 204 to swing upwards, thereby causing the upper conveyor belt 106 to vibrate upwards, slightly lifting and loosening the sludge strips. The sludge strips are then transferred to the lower conveyor belt 107. The lifting component 200 within the lower conveyor belt 107 also oscillates periodically under the drive of the transmission shaft 108, causing the lower conveyor belt 107 to vibrate continuously, further preventing sludge blockage and promoting... Hot air flows between the mud strips; during this process, the hot air drying component 104 continuously conveys high-temperature gas to the lower conveyor belt 107 for drying. At the same time, the lifting column 203a moves with the rise and fall of the connecting plate 202 and the counterweight block 203, and drives the lifting plate 302a and the second pressure block 302 to rise. Through the linkage action of the connecting rod 304 and the central shaft 305, the first pressure block 301 and the second pressure block 302 alternately descend, elastically striking the surface of the mud strips on the lower conveyor belt 107 to form uniform micro-cracks, which facilitates the hot air to penetrate into the interior and accelerate drying. The dried mud strips finally fall into the discharge bin 105 and are discharged through the screw conveyor shaft. The moisture generated during the drying process is condensed and discharged from the system after being treated by the condensation circulation component 103, realizing continuous reduction treatment of sludge.

[0079] Although embodiments of the invention have been shown and described (see the detailed description above), 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 invention, the scope of which is defined by the appended claims and their equivalents.
