Specifically, this device is mainly used to dry and dehydrate solid waste with a high moisture content (such as sludge, industrial waste residue, etc.).

[0010] Furthermore, a trapezoidal groove is provided on the right inner wall of the drying cylinder, a strip rod is fixedly installed in the trapezoidal groove, and a cleaning plate is slidably sleeved on the strip rod.

[0011] Furthermore, two cleaning springs are sleeved on the strip rod, and the ends of the two cleaning springs that are away from each other are fixedly connected to the trapezoidal groove, and the ends of the two cleaning springs that are close to each other are fixedly connected to the cleaning plate, and a plurality of oblique circular grooves are opened on the cleaning plate.

[0012] Furthermore, the exhaust mechanism includes an L-shaped hollow plate fixedly installed at the bottom of the drying cylinder, a telescopic spring is fixedly installed on the right inner wall of the L-shaped hollow plate, a T-shaped arc block is fixedly installed on the left end of the telescopic spring, and the left end of the T-shaped arc block slides and extends outside the L-shaped hollow plate.

[0014] Furthermore, a grooved limit plate is slidably installed in the rectangular box, and several hollow blocks are fixedly installed on the right side of the grooved limit plate. The front and back sides of several of the hollow blocks are respectively provided with strip-shaped ventilation grooves, and two exhaust springs are fixedly installed on the left side of the grooved limit plate. The left ends of the two exhaust springs are fixedly connected to the rectangular box.

[0015] The present invention has the following beneficial effects: (1) The present invention provides a solid waste drying treatment device. When in use, the sludge is poured into the drying cylinder through the feed pipe so that the height of the sludge is not higher than the height of the drive shaft. Then the drive motor is started and hot air is input into the drying cylinder through the air inlet pipe. The drive motor drives the drive shaft to rotate, and the drive shaft drives a plurality of mounting racks to rotate. The mounting racks drive the L-shaped plates to rotate. When the L-shaped plates and the trapezoidal plates rotate, the sludge is turned up by the centrifugal force. When the L-shaped plates drive the sludge to the highest point, the sludge falls out of the strip groove under the action of gravity and returns to the sludge in the drying cylinder. The separated sludge will move along the inside of the drying cylinder under the action of the trapezoidal plates. During this process, the hot air will increase the contact area with the sludge, thereby drying and dehydrating the sludge more effectively. Correspondingly, the sludge will be stirred during the rotation of the L-shaped plate and the trapezoidal plate, so that the sludge will fully contact with the hot air, thereby improving the efficiency of drying and dehydration. During the rotation of the trapezoidal plate, it will contact the inner wall of the drying cylinder and scrape off the sludge on the inner wall of the drying cylinder, which can prevent the sludge from sticking to the inner wall of the drying cylinder after drying, avoid jamming of the device, and save the process of manual cleaning of the inner wall of the drying cylinder; (2) The present invention provides a solid waste drying and processing device. During the rotation of the trapezoidal plate, the inclined surface of the trapezoidal plate is in contact with the rectangular block. When the trapezoidal plate enters the groove of the arc-shaped closing plate, the limit spring will contact the trapezoidal plate with the arc-shaped closing plate under the action of elastic force, ensuring that the sludge in the groove of the arc-shaped closing plate is also stirred, further improving the comprehensiveness of the sludge drying. When the trapezoidal plate contacts the rectangular block, the trapezoidal plate will slide into the hollow groove, and the corresponding limit spring will be compressed and deformed, ensuring that the trapezoidal plate passes through the rectangular block smoothly and continuously turns over the sludge. After the sludge is dried and dehydrated, the driving motor is rotated in the reverse direction, and the driving motor will drive the trapezoidal plate to reverse. At this time, the flat surface of the trapezoidal plate contacts the rectangular block, and the rectangular block will drive the arc-shaped closing plate to open under the push of the trapezoidal plate. At this time, the effect of automatic material discharge can be achieved, while saving manpower. When the arc-shaped closing plate is opened, the sludge on the inner wall of the arc-shaped closing plate will also be scraped off under the contact action of the arc groove, further enhancing the self-cleaning effect. (3) The present invention provides a solid waste drying treatment device. During the rotation of the L-shaped plate, the L-shaped plate will contact the arc surface of the T-shaped arc surface block. Under the action of the arc surface limit and friction, the L-shaped plate will drive the T-shaped arc surface block to move. At this time, the T-shaped arc surface block will drive the cleaning plate to move. The corresponding two cleaning springs will undergo tensile deformation and compression deformation respectively. After the L-shaped plate drives the T-shaped arc surface block to move a certain distance, when the elastic force of the cleaning spring is greater than the friction force of the T-shaped arc surface block, the T-shaped arc surface block will slide into the L-shaped hollow plate. At this time, the telescopic spring will undergo compression deformation, and the corresponding T-shaped arc surface block will leave the L-shaped plate. At this time, the cleaning plate will swing left and right under the action of the elastic force of the cleaning spring. The cleaning plate will clean the sludge thrown onto the strip chute when the sludge is turned over. The cleaned sludge will fall from the trapezoidal chute into the drying cylinder to prevent the sludge from clogging the strip chute and affecting the normal discharge of gas in the drying cylinder. (4) The present invention provides a solid waste drying treatment device. As hot air is continuously input into the drying cylinder, the air pressure in the drying cylinder will increase, and the hot air and water vapor released from the sludge will enter the rectangular box from the strip inclined groove. At this time, the gas will push the hollow block to move in the direction close to the circular exhaust pipe, and the hollow block will drive the grooved limit plate to move. At this time, the exhaust spring will be stretched and deformed. When the strip air-permeable groove on the hollow block enters the circular exhaust pipe, the gas will enter the circular exhaust pipe and be discharged from the circular exhaust pipe. At this time, under the action of the exhaust spring, the gas discharge can be effectively controlled, so that the gas in the drying cylinder can only be discharged but not entered, thereby avoiding hot gas leakage affecting the drying and dehydration effect of the sludge.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-8 As shown, the present invention is a solid waste drying treatment device, comprising a drying cylinder 1, and further comprising: The turning mechanism is arranged in the drying cylinder 1 and includes a support frame 101 arranged below the drying cylinder 1. The turning mechanism is used to continuously turn up the sludge when drying the sludge, thereby increasing the contact surface between the sludge and the hot air; The cleaning mechanism is arranged in the drying cylinder 1. The cleaning mechanism includes an arc-shaped groove 2 arranged in the drying cylinder 1. The cleaning mechanism is used to ensure the sealing of the drying cylinder 1 when drying the sludge and automatically open the drying cylinder 1 to discharge the material after the drying work is completed; The exhaust mechanism is arranged on the drying cylinder 1. The exhaust mechanism includes an L-shaped hollow plate 3 arranged in the drying cylinder 1. The exhaust mechanism is used to clean the sludge in the exhaust port during the sludge drying process to prevent the sludge from solidifying and clogging the exhaust port after drying.

[0022] like Figure 2 As shown, the flipping mechanism includes two support plates 102 fixedly mounted on the top of the support frame 101, and the two support plates 102 are fixedly connected to the drying cylinder 1. A drive shaft 103 is rotatably installed in the drying cylinder 1, and a drive motor 104 is fixedly mounted on the left side of the corresponding support plate 102, and the output shaft of the drive motor 104 is fixedly connected to the drive shaft 103.

[0023] The driving motor 104 drives the driving shaft 103 to rotate, the driving shaft 103 drives a plurality of mounting brackets 105 to rotate, and the mounting brackets 105 drive the L-shaped plate 106 to rotate.

[0024] like Figure 3 As shown, a plurality of mounting brackets 105 are fixedly mounted on the outer wall of the driving shaft 103 , and L-shaped plates 106 are fixedly mounted on ends of the plurality of mounting brackets 105 away from each other, and strip grooves 107 are respectively formed on the plurality of L-shaped plates 106 .

[0025] The L-shaped plate 106 and the trapezoidal plate 110 will turn over the sludge under the action of centrifugal force when rotating. When the L-shaped plate 106 drives the sludge to the highest point, the sludge will fall out of the strip groove 107 under the action of gravity and return to the sludge in the drying cylinder 1.

[0026] like Figure 2 and Figure 5 As shown, several L-shaped plates 106 are respectively provided with hollow grooves 108, and several limit springs 109 are respectively fixedly installed on the inner walls of the several hollow grooves 108. The ends of the several limit springs 109 are respectively fixedly installed with trapezoidal plates 110, and the several trapezoidal plates 110 are respectively slid and extended to the outside of the several hollow grooves 108 and contact the inner wall of the drying cylinder 1. A feeding pipe 111 is fixedly installed on the top of the drying cylinder 1, and a closing valve is provided on the feeding pipe 111. An air intake pipe 112 is fixedly installed on the left side of the drying cylinder 1, and the air intake pipe 112 is communicated with the drying cylinder 1.

[0027] Correspondingly, part of the sludge will move along the inside of the drying cylinder 1 under the action of the trapezoidal plate 110. During this process, the hot air will increase the contact area with the sludge, thereby drying and dehydrating the sludge more effectively. Correspondingly, the sludge will be stirred during the rotation of the L-shaped plate 106 and the trapezoidal plate 110, so that the sludge is fully in contact with the hot air, thereby improving the efficiency of drying and dehydration. During the rotation of the trapezoidal plate 110, it will contact the inner wall of the drying cylinder 1 and scrape off the sludge on the inner wall of the drying cylinder 1, which can prevent the sludge from sticking to the inner wall of the drying cylinder 1 after drying, avoid jamming of the device, and save the process of manually cleaning the inner wall of the drying cylinder 1.

[0028] like Figure 4 and Figure 5As shown, the cleaning mechanism includes an arc-shaped groove 2 opened in the drying cylinder 1, and a plurality of arc-shaped springs 201 are fixedly installed on the top inner wall of the arc-shaped groove 2. The bottom ends of the plurality of arc-shaped springs 201 are respectively fixedly installed with arc-shaped closing plates 202, and the arc-shaped closing plates 202 are slidably connected to the arc-shaped groove 2. A rectangular block 203 is fixedly installed through the arc-shaped closing plate 202, and a handle 204 is fixedly installed at the bottom end of the rectangular block 203.

[0029] During the rotation of the trapezoidal plate 110, the inclined surface of the trapezoidal plate 110 is in contact with the rectangular block 203. When the trapezoidal plate 110 enters the groove of the arc-shaped closing plate 202, the limit spring 109 will, under the action of elastic force, bring the trapezoidal plate 110 into contact with the arc-shaped closing plate 202, ensuring that the sludge in the groove of the arc-shaped closing plate 202 will also be stirred, thereby further improving the comprehensiveness of sludge drying.

[0030] like Figure 6 As shown, a trapezoidal groove 205 is provided on the right inner wall of the drying cylinder 1 , a strip rod 206 is fixedly installed in the trapezoidal groove 205 , and a cleaning plate 207 is slidably sleeved on the strip rod 206 .

[0031] The cleaning plate 207 will clean the sludge thrown onto the strip chute 304 when the sludge is turned over. The cleaned sludge will fall into the drying cylinder 1 from the trapezoidal groove 205 to prevent the sludge from clogging the strip chute 304 and affecting the normal discharge of gas in the drying cylinder 1.

[0032] like Figure 6 As shown, two cleaning springs 208 are sleeved on the strip rod 206, and the ends of the two cleaning springs 208 that are away from each other are fixedly connected to the trapezoidal groove 205, and the ends of the two cleaning springs 208 that are close to each other are fixedly connected to the cleaning plate 207, and a number of oblique circular grooves 209 are opened on the cleaning plate 207.

[0033] The corresponding T-shaped arc block 302 will leave the L-shaped plate 106, and at this time, the cleaning plate 207 will rock left and right under the elastic force of the cleaning spring 208.

[0034] like Figure 6 As shown, the exhaust mechanism includes an L-shaped hollow plate 3 fixedly mounted on the bottom of the drying cylinder 1, a telescopic spring 301 is fixedly mounted on the right inner wall of the L-shaped hollow plate 3, a T-shaped arc block 302 is fixedly mounted on the left end of the telescopic spring 301, and the left end of the T-shaped arc block 302 slides and extends to the outside of the L-shaped hollow plate 3.

[0035] During the rotation of the L-shaped plate 106, it will contact the arc surface of the T-shaped arc surface block 302. Under the action of the arc surface limitation and friction, the L-shaped plate 106 will drive the T-shaped arc surface block 302 to move. At this time, the T-shaped arc surface block 302 will drive the cleaning plate 207 to move, and the corresponding two cleaning springs 208 will undergo tensile deformation and compression deformation respectively. After the L-shaped plate 106 drives the T-shaped arc surface block 302 to move a distance, when the elastic force of the cleaning spring 208 is greater than the friction force of the T-shaped arc surface block 302, the T-shaped arc surface block 302 will slide into the L-shaped hollow plate 3.

[0036] like Figure 8 As shown, a rectangular box 303 is fixedly installed on the right side of the drying cylinder 1, and a plurality of strip-shaped inclined slots 304 are opened on the left side of the rectangular box 303. The rectangular box 303 is communicated with the drying cylinder 1. A plurality of circular exhaust pipes 305 are fixedly installed on the right side of the rectangular box 303. The plurality of circular exhaust pipes 305 are communicated with the rectangular box 303.

[0037] As hot air is continuously input into the drying cylinder 1 , the air pressure in the drying cylinder 1 increases, and the hot air and water vapor released from the sludge enter the rectangular box 303 through the strip chute 304 .

[0038] like Figure 7 and Figure 8 As shown, a grooved limit plate 306 is slidably installed in the rectangular box 303, and a number of hollow blocks 307 are fixedly installed on the right side of the grooved limit plate 306. The front and back sides of the several hollow blocks 307 are respectively provided with strip-shaped ventilation grooves, and two exhaust springs 308 are fixedly installed on the left side of the grooved limit plate 306. The left ends of the two exhaust springs 308 are fixedly connected to the rectangular box 303.

[0039] At this time, the gas will push the hollow block 307 to move toward the circular exhaust pipe 305, and the hollow block 307 will drive the grooved limit plate 306 to move. At this time, the exhaust spring 308 will be stretched and deformed. When the strip-shaped air-permeable groove on the hollow block 307 enters the circular exhaust pipe 305, the gas will enter the circular exhaust pipe 305 and be discharged from the circular exhaust pipe 305. At this time, under the action of the exhaust spring 308, the discharge of the gas can be effectively controlled, so that the gas in the drying cylinder 1 can only be discharged but not entered, thereby avoiding hot gas leakage affecting the drying and dehydration effect of the sludge.

[0040] When in use, pour the sludge into the drying cylinder 1 through the feed pipe 111 so that the height of the sludge is no higher than the height of the drive shaft 103. Then start the drive motor 104 and input hot air into the drying cylinder 1 through the air inlet pipe 112. The drive motor 104 drives the drive shaft 103 to rotate, and the drive shaft 103 drives several mounting racks 105 to rotate. The mounting rack 105 drives the L-shaped plate 106 to rotate. The L-shaped plate 106 and the trapezoidal plate 110 will turn over the sludge under the action of centrifugal force when rotating. When the L-shaped plate 106 drives the sludge to the highest point, the sludge will fall out of the strip groove 107 under the action of gravity and return to the sludge in the drying cylinder 1. Correspondingly, part of the sludge will move along the inside of the drying cylinder 1 under the action of the trapezoidal plate 110. During this process, the hot air will increase the contact area with the sludge, thereby more effectively drying and dehydrating the sludge. Correspondingly, the sludge will be stirred during the rotation of the L-shaped plate 106 and the trapezoidal plate 110, so that the sludge is fully in contact with the hot air, thereby improving the efficiency of drying and dehydration. During the rotation of the trapezoidal plate 110, it will contact the inner wall of the drying cylinder 1 and scrape off the sludge on the inner wall of the drying cylinder 1, thereby preventing the sludge from sticking to the inner wall of the drying cylinder 1 after drying, avoiding jamming of the device, and saving the process of manually cleaning the inner wall of the drying cylinder 1. During the rotation of the trapezoidal plate 110, the inclined surface of the trapezoidal plate 110 has been in contact with the rectangular block 203. When the trapezoidal plate 110 enters the groove of the arc-shaped closing plate 202, the limit spring 109 will contact the trapezoidal plate 110 with the arc-shaped closing plate 202 under the action of elastic force, ensuring that the sludge in the groove of the arc-shaped closing plate 202 will also be stirred, further improving the comprehensiveness of the sludge drying. When the trapezoidal plate 110 contacts the rectangular block 203, the trapezoidal plate 110 will slide into the hollow groove 108, and the corresponding limit spring 109 will be compressed and deformed to ensure that the trapezoidal plate 110 10 passes through the rectangular block 203 smoothly and continuously turns over the sludge. After the sludge is dried and dehydrated, the driving motor 104 is rotated in the opposite direction. The driving motor 104 will drive the trapezoidal plate 110 to reverse. At this time, the plane of the trapezoidal plate 110 contacts the rectangular block 203. The rectangular block 203 will drive the arc-shaped closing plate 202 to open under the push of the trapezoidal plate 110. At this time, the effect of automatic discharge can be achieved, and manpower is saved. When the arc-shaped closing plate 202 is opened, the sludge on the inner wall of the arc-shaped closing plate 202 will also be scraped off under the contact action of the arc groove 2, further enhancing the self-cleaning effect. During the rotation of the L-shaped plate 106, it will contact the arc surface of the T-shaped arc surface block 302. Under the action of the limit and friction of the arc surface, the L-shaped plate 106 will drive the T-shaped arc surface block 302 to move. At this time, the T-shaped arc surface block 302 will drive the cleaning plate 207 to move, and the corresponding two cleaning springs 208 will respectively undergo tensile deformation and compression deformation. After the L-shaped plate 106 drives the T-shaped arc surface block 302 to move a distance, when the elastic force of the cleaning spring 208 is greater than the friction force of the T-shaped arc surface block 302, the T-shaped arc surface block 307 will be moved. 302 will slide into the L-shaped hollow plate 3. At this time, the telescopic spring 301 will be compressed and deformed, and the corresponding T-shaped arc block 302 will leave the L-shaped plate 106. At this time, the elastic force of the cleaning spring 208 will cause the cleaning plate 207 to swing left and right. The cleaning plate 207 will clean the sludge thrown onto the strip chute 304 when the sludge is turned over. The cleaned sludge will fall into the drying cylinder 1 through the trapezoidal groove 205, preventing the sludge from clogging the strip chute 304 and affecting the normal discharge of gas in the drying cylinder 1. As hot air is continuously input into the drying cylinder 1, the air pressure in the drying cylinder 1 will increase, and the hot air and water vapor released from the sludge will enter the rectangular box 303 from the strip chute 304. At this time, the gas will push the hollow block 307 to move toward the direction close to the circular exhaust pipe 305, and the hollow block 307 will drive the slotted limit plate 306 to move. At this time, the exhaust spring 308 will be stretched and deformed. When the strip air-permeable groove on the hollow block 307 enters the circular exhaust pipe 305, the gas will enter the circular exhaust pipe 305 and be discharged from the circular exhaust pipe 305. At this time, under the action of the exhaust spring 308, the discharge of the gas can be effectively controlled, so that the gas in the drying cylinder 1 can only be discharged but not entered, thereby avoiding hot air leakage affecting the drying and dehydration effect of the sludge.
