Description

Technical Field

[0001] This utility model relates to the field of sludge drying technology, and in particular to a material anti-sticking structure for a sludge steam dryer. Background Technology

[0002] Chinese patent application number 202121635592.6 discloses a high-efficiency, environmentally friendly, and energy-saving sludge dryer. The dryer involves injecting sludge into the drum through a feed inlet and steam into the drum through a steam inlet, where the steam dries the sludge. When the motor is turned on, the aluminum alloy and copper layers of the drum wall have excellent heat absorption and dissipation properties. Excess heat is absorbed by the drum, and the heat is drawn from one end of the drum cavity through a fan and conveying pipe, then inputted from the other end, creating a heat energy cycle between the drum and the conveying pipe, thus utilizing excess heat multiple times. The phenolic and polyurethane layers of the conveying pipe wall have excellent insulation properties, effectively preventing heat loss during transport. Excess pressure and heat inside the drum are discharged through the exhaust pipe and exhaust valve.

[0003] Although the aforementioned comparative documents can absorb excess heat from the inside of the rotating drum through the aluminum alloy and copper drum walls, sludge will adhere to the inner wall of the drum during the sludge drying process. Over time, excessive sludge on the drum wall will affect the heat absorption and dissipation effect of the drum wall, thus preventing the subsequent conveying pipe from utilizing the heat inside the drum, hindering effective energy circulation, causing subsequent manual cleaning trouble, and reducing the efficiency of sludge drying.

[0004] Therefore, how to improve the cleaning effect of the inner wall of the anti-sticking structure of a sludge steam dryer is a technical problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a material anti-sticking structure for a sludge steam dryer, so as to improve the working efficiency of a material anti-sticking structure for a sludge steam dryer.

[0006] To achieve the above objectives, this utility model provides a material anti-sticking structure for a sludge steam dryer, comprising:

[0007] Cleaning components installed inside the drum;

[0008] The cleaning assembly includes at least two rotating shafts, with rotating rods installed inside the rotating shafts. A first bevel gear is installed on the rotating rod, and at least two second bevel gears mesh with the first bevel gear. A rotating cylinder is installed on each of the second bevel gears, and a screw is threadedly connected inside the rotating cylinder. A scraper is fixedly connected to one end of the screw. At least two limiting frames are installed on the rotating shafts, and the scraper moves within the inner wall of the limiting frames. Two brushes, one positive and one negative, are installed on the motor.

[0009] The rotating shaft is rotated via a transmission assembly, which includes a motor and a gear mechanism for driving the rotating shaft to rotate.

[0010] The transmission assembly is mounted on the drum via a mounting assembly;

[0011] The support component is installed below the cleanup component.

[0012] The gear mechanism includes a first gear and a second gear. The first gear is located at the center of the gear ring. The first gear meshes with two second gears, and the two second gears are fixedly connected to their respective rotating shafts.

[0013] The mounting assembly includes a mounting plate, a support plate mounted on one side of the mounting plate, two through holes on the support plate, a rotating shaft rotating inside the through holes, a circular frame fixedly connected to the support plate, the circular frame being rotatably connected to the roller, a feed hopper mounted on the circular frame, and a second limiting plate mounted on the mounting plate.

[0014] The support assembly includes a support frame, with two support seats mounted on the top of the support frame. Two limiting members are mounted on the top of each of the two support seats. A fixing seat is mounted on the support frame, and the fixing seat is located between the two support seats.

[0015] A third gear is mounted on the fixed base via a motor, and a roller is mounted on one side of each support base.

[0016] A toothed ring is installed on the roller, and two circular rings are installed on the roller, with the toothed ring located between the two circular rings.

[0017] The gear ring meshes with the third gear, and the two rings are respectively tangent to their corresponding rollers.

[0018] The discharge end of the roller is rotatably connected to a discharge barrel. The bottom of the discharge barrel has a discharge port, and a discharge hopper is installed on the discharge port. The discharge barrel is fixedly connected to the support frame through a first limiting plate. The discharge barrel has two mounting holes. The other end of the rotating shaft rotates inside the mounting holes. An electric coil is installed on the discharge barrel. The electric coil and the mounting hole are on the same center. The electric coil has positive and negative poles.

[0019] The outer surface of the support plate is rotatably connected to the inner surface of the roller.

[0020] The second limiting plate is fixedly connected to the support frame.

[0021] This invention discloses a material anti-sticking structure for a sludge steam dryer. A motor drives a first gear to rotate, which in turn drives two second gears. The rotation of the second gears drives a rotating shaft, which in turn drives the motor. The motor's brushes rotate along the coils. When the motor is energized, its output shaft drives a rotating rod. This rotation of the rotating rod causes a first bevel gear to rotate clockwise, which in turn drives a second bevel gear located above the rotating rod to rotate counter-clockwise. The first bevel gear also drives a second bevel gear located below the rotating rod to rotate clockwise. Each of the two second bevel gears drives its own rotating drum to rotate, which in turn drives a screw. The two screws push corresponding scrapers to move in opposite directions. The scrapers extend along the limiting frame from the rotating shaft, causing them to rotate. Under the rotation of the shaft, the scrapers remove the sludge adhering to the inner wall of the drum. This solution eliminates the need for manual cleaning, improving the working efficiency of the sludge dryer and enabling it to operate efficiently.

[0033] The core of this utility model is to provide a material anti-sticking structure for a sludge steam dryer, so as to improve the effective load-bearing capacity of the material anti-sticking structure for a sludge steam dryer.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Please refer to Figures 1 to 7 This utility model discloses a material anti-sticking structure for a sludge steam dryer:

[0036] Includes: a cleaning assembly 2 installed inside the drum 1;

[0037] The cleaning component 2 includes at least two rotating shafts 201. A rotating rod 203 is mounted inside the rotating shaft 201 via a motor 209. A first bevel gear 204 is mounted on the rotating rod 203. At least two second bevel gears 207 mesh with the first bevel gear 204. A rotating drum 205 is mounted on the second bevel gears 207. A screw 206 is threadedly connected inside the rotating drum 205. A scraper 202 is fixedly connected to one end of the screw 206. At least two limiting frames 208 are mounted on the rotating shaft 201. The scraper 202 moves within the inner wall of the limiting frame 208. Two brushes 210, which are positive and negative, are mounted on the motor 209.

[0038] The rotating shaft 201 rotates via the transmission assembly 3, which includes a motor and a gear mechanism 301 for driving the rotating shaft 201 to rotate.

[0039] Transmission assembly 3 is mounted on roller 1 via mounting assembly 4;

[0040] Support component 5 is installed below cleaning component 2.

[0041] The gear mechanism 301 includes a first gear 302 and a second gear 303. The first gear 302 is located at the center of the gear ring. The first gear 302 meshes with two second gears 303 respectively. The two second gears 303 are fixedly connected to the corresponding rotating shafts 201 respectively.

[0042] Mounting assembly 4 includes mounting plate 401, a support plate 402 is mounted on one side of mounting plate 401, the support plate 402 has two through holes 403, a circular frame 404 is fixedly connected to the support plate 402, the circular frame 404 is rotatably connected to roller 1, a feed hopper 405 is mounted on the circular frame 404, and a second limiting plate 406 is mounted on mounting plate 401.

[0043] The support assembly 5 includes a support frame 501, the top of which is mounted on two support seats 502. Two limiting members 503 are mounted on the top of each of the two support seats 502. A fixing seat 504 is mounted on the support frame 501 and is located between the two support seats 502.

[0044] A third gear 505 is mounted on the fixed base 504 via a motor, and a roller 506 is mounted on one side of each support base 502.

[0045] A toothed ring 101 is installed on the roller 1, and two circular rings 102 are installed on the roller 1, with the toothed ring 101 located between the two circular rings 102.

[0046] The gear ring 101 meshes with the third gear 505, and the two rings 102 are tangent to the corresponding rollers 506 respectively.

[0047] The discharge end of the roller 1 is rotatably connected to a discharge barrel 6. The discharge barrel 6 has a discharge port 601 at its bottom and a discharge hopper 602 installed on the discharge port 601. The discharge barrel 6 is fixedly connected to the support frame 501 through a first limiting plate 603. The discharge barrel 6 has two mounting holes 604. The other end of the rotating shaft 201 rotates inside the mounting holes 604. An electric coil 605 is installed on the discharge barrel 6. The electric coil 605 and the mounting holes 604 are on the same center. The electric coil 605 has positive and negative poles.

[0048] The electric coil 605 is connected to an external switch. When the motor 209 drives the rotating rod 203 to rotate and the scraper 202 is fully extended, the external switch is turned off to de-energize the electric coil 605. When the scraper 202 cleans the sludge on the inner wall of the roller 1, the external switch is turned on to energize the electric coil 605. When the motor 209 rotates, the brush 210 on the motor 209 contacts the electric coil 605, the motor 209 is energized, and the output shaft of the motor 209 rotates.

[0049] The outer surface of the support plate 402 is rotatably connected to the inner surface of the roller 1.

[0050] The second limiting plate 406 is fixedly connected to the support frame 501.

[0051] The motor on mounting plate 401 drives the first gear 302 to rotate, which in turn drives the two second gears 303 to rotate. The rotation of the two second gears 303 drives the rotating shaft 201 to rotate, which in turn drives the motor 209 to rotate. The brushes 210 on the motor 209 rotate along the coil 605. When the motor 209 is energized, its output shaft drives the rotating rod 203 to rotate. The rotation of the rotating rod 203 drives the first bevel gear 204 to rotate clockwise, which in turn drives the second bevel gear 207 located above the rotating rod 203 to rotate counterclockwise. The first bevel gear 204 drives the second bevel gear 207 located below the rotating rod 203 to rotate clockwise. As the clock hand rotates, the two second bevel gears 207 drive the rotating drums 205 on their respective sides to rotate. The rotation of the rotating drums 205 drives the screws 206 to rotate. The two screws 206 push the corresponding scrapers 202 to move in opposite directions. The scrapers 202 extend along the limit frame 208 and the rotating shaft 201 to drive the scrapers 202 to rotate. At this time, under the rotation of the rotating shaft 201, the scrapers 202 scrape off the sludge attached to the inner wall of the roller 1. The two ends of the rotating shaft 201 rotate inside the through hole 403 and the mounting hole 604 respectively, making the rotating shaft 201 more stable in use. When the motor 209 drives the rotating rod 203 to rotate and the scrapers 202 are fully extended, the external switch is turned off to de-energize the coil 605.

[0052] After the cleaning component 2 cleans the inner wall of the roller 1, the external switch is turned on, the electric coil 605 is energized, and the brush 210 and the electric coil 605 are energized when the motor 209 rotates. The output shaft of the motor 209 flips, the rotating rod 203 rotates counterclockwise, driving the first bevel gear 204 to rotate counterclockwise. The first bevel gear 204 drives the second bevel gear 207 located above the rotating rod 203 to rotate clockwise. The first bevel gear 204 drives the second bevel gear 207 located below the rotating rod 203 to rotate counterclockwise. The two second bevel gears 207 drive the rotating drum 205 on their respective drums to rotate. The rotation of the rotating drum 205 drives the screw 206 to rotate. The two screws 206 drive the corresponding scrapers 202 to move in opposite directions. The scrapers 202 retract along the inner wall of the limit frame 208. When the scrapers 202 are completely retracted, the external switch of the limit frame 208 is turned off, and the electric coil 605 is de-energized.

[0053] The motor drives the third gear 505 to rotate, and the third gear 505 drives the roller 1 to rotate by meshing with the gear ring 101. At the same time, the roller 1 rotates and the ring 102 on itself drives the roller 506 to rotate. Because the discharge bucket 6 and the mounting assembly 4 are fixed to the support frame 501 by the first limiting plate 603 and the second limiting plate 406 respectively, and the discharge bucket 6 and the mounting assembly 4 are rotatably connected to the roller 1, the discharge bucket 6 and the mounting assembly 4 do not rotate when the roller 1 rotates. Therefore, when the cleaning assembly 2 rotates to scrape the sludge on the inner wall of the roller 1, the roller 1 does not rotate.

[0054] When the drum 1 is drying the sludge, the drum 1 is rotating. When the drum 1 is rotating, the limit frame 208 on the cleaning component 2 can act as a stirring rod to stir the sludge in the drum 1, increase the contact area between the sludge and the steam, and facilitate the drying speed of the sludge.

[0055] After the cleaning component 2 finishes cleaning the sludge on the inner wall of the drum 1, the cleaning component 2 stops rotating. Because the sludge steam dryer operates in a slightly tilted state, the drum 1 in this application is slightly tilted towards the discharge bucket 6. Therefore, when the drum 1 rotates, the sludge that has been cleaned off moves towards the discharge bucket 6 through the rotation of the drum 1 and the tilt of the drum 1. The sludge is finally discharged into the external collection device through the discharge hopper 602.
