When the L-shaped plate and trapezoidal plate of this invention rotate, they will turn the sludge up under the action of centrifugal force. When the L-shaped plate carries the sludge to the highest point, the sludge will fall out from the strip groove under the action of gravity and return to the sludge in the drying drum.

During this process, the hot air will increase the contact area with the sludge, thereby more effectively drying and dewatering the sludge.

Description

Technical Field

[0001] This invention relates to the field of solid waste treatment equipment technology, specifically to a solid waste drying treatment device. Background Technology

[0002] This introduction to a solid waste drying and treatment device aims to explain the basic uses, working principle, and importance of this equipment in solid waste treatment. Specifically, this device is mainly used for drying and dehydrating solid wastes containing high moisture content (such as sludge, industrial waste residue, etc.).

[0003] Traditional equipment has a relatively simple stirring structure, which makes it difficult to fully agitate and heat the sludge, resulting in low drying efficiency and difficulty in removing moisture from the sludge. In the existing technology, the sludge lacks an effective agitation and dispersion structure during the drying process, resulting in a small contact area between the hot air and the sludge and low heat transfer efficiency, which prolongs the drying time and increases energy consumption. Summary of the Invention

[0004] The purpose of this invention is to provide a solid waste drying and treatment device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0013] Furthermore, the cleaning mechanism includes an arc-shaped groove inside the drying cylinder. Several arc-shaped springs are fixedly installed on the top inner wall of the arc-shaped groove.

A rectangular block is fixedly installed through the arc-shaped closing plate. A handle is fixedly installed at the bottom end of the rectangular block.

[0014] Furthermore, a trapezoidal groove is provided on the inner right side of the drying cylinder, and a strip rod is fixedly installed in the trapezoidal groove. A cleaning plate is slidably sleeved on the strip rod.

[0015] Furthermore, two cleaning springs are sleeved on the strip rod. The ends of the two cleaning springs that are far apart 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. The cleaning plate has several oblique circular grooves.

[0016] Furthermore, the exhaust mechanism includes an L-shaped hollow plate fixedly installed at the bottom of the drying cylinder, a telescopic spring fixedly installed on the inner right side of the L-shaped hollow plate, a T-shaped arc block fixedly installed at the left end of the telescopic spring, and the left end of the T-shaped arc block slidingly extending outside the L-shaped hollow plate.

[0017] Furthermore, a rectangular box is fixedly installed on the right side of the drying cylinder, and several strip-shaped inclined grooves are opened on the left side of the rectangular box. The rectangular box is connected to the drying cylinder, and several circular exhaust pipes are fixedly installed on the right side of the rectangular box, and the several circular exhaust pipes are connected to the rectangular box.

[0018] Furthermore, a grooved limiting plate is slidably installed inside the rectangular box. Several hollow blocks are fixedly installed on the right side of the grooved limiting plate. The front and back of the hollow blocks are respectively provided with strip-shaped ventilation grooves. Two exhaust springs are fixedly installed on the left side of the grooved limiting plate. The left ends of the two exhaust springs are fixedly connected to the rectangular box.

[0019] The present invention has the following beneficial effects:

[0020] (1) In this invention, a solid waste drying treatment device is used such that sludge is poured into the drying cylinder through the feed pipe, ensuring the sludge height is no higher than the height of the drive shaft. Then, the drive motor is started, and hot air is introduced into the drying cylinder through the air inlet pipe. The drive motor drives the drive shaft to rotate, which in turn drives several mounting frames to rotate. The mounting frames drive L-shaped plates to rotate. When the L-shaped plates and trapezoidal plates rotate, they will cause the sludge to be turned up by centrifugal force. When the L-shaped plates carry the sludge to the highest point, the sludge will fall out of the strip trough under the action of gravity and return to the sludge in the drying cylinder. Correspondingly, some of the sludge is discharged. The sludge moves along the inside of the drying cylinder under the action of the trapezoidal plates. During this process, the hot air increases the contact area with the sludge, thus drying and dehydrating the sludge more effectively. Correspondingly, the sludge is also stirred during the rotation of the L-shaped and trapezoidal plates, so that the sludge can fully contact the hot air and improve the drying and dehydration efficiency. During the rotation of the trapezoidal plates, they will contact the inner wall of the drying cylinder and scrape the sludge on the inner wall of the drying cylinder clean. This can prevent the sludge from sticking to the inner wall of the drying cylinder after drying, avoid the device from jamming, and save the manual cleaning process of the inner wall of the drying cylinder.

[0021] (2) In the solid waste drying treatment device of the present invention, during the rotation of the trapezoidal plate, the inclined surface of the trapezoidal plate is in contact with the rectangular card block. When the trapezoidal plate enters the groove of the arc-shaped closed plate, the limiting spring will contact the trapezoidal plate with the arc-shaped closed plate under the action of elastic force, ensuring that the sludge in the groove of the arc-shaped closed plate will also be stirred, further improving the overall drying of the sludge. When the trapezoidal plate contacts the rectangular card block, the trapezoidal plate will slide into the hollow groove, and the corresponding limiting spring will be compressed and deformed, ensuring that the trapezoidal plate passes smoothly through the rectangular card block and continuously turns the sludge. After the sludge is dried and dewatered, the drive motor is rotated in the opposite direction. The drive motor will drive the trapezoidal plate to reverse. At this time, the plane of the trapezoidal plate contacts the rectangular card block. The rectangular card block will drive the arc-shaped closed plate to open under the push of the trapezoidal plate. At this time, the automatic feeding effect can be achieved, and manpower is saved. When the arc-shaped closed plate is opened, the sludge on the inner wall of the arc-shaped closed plate will also be scraped off under the contact action of the arc groove, further enhancing the self-cleaning effect.

[0022] (3) In the solid waste drying treatment device of the present invention, during the rotation of the L-shaped plate, it will contact the arc surface of the T-shaped arc block. Under the limiting and friction of the arc surface, the L-shaped plate will drive the T-shaped arc block to move. At this time, the T-shaped arc block will drive the cleaning plate to move. The two cleaning springs will undergo tensile deformation and compression deformation respectively. After the L-shaped plate drives the T-shaped arc 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 block, the T-shaped arc block will slide into the L-shaped hollow plate. At this time, the telescopic spring will undergo compression deformation, and the T-shaped arc block will leave the L-shaped plate. At this time, under the elastic force of the cleaning spring, the cleaning plate will sway left and right. The cleaning plate will clean the sludge that is thrown onto the strip inclined chute when the sludge is turned over. The cleaned sludge will fall into the drying cylinder from the trapezoidal chute, so as to avoid the sludge blocking the strip inclined chute and affecting the normal emission of gas in the drying cylinder.

[0023] (4) In the solid waste drying treatment device of the present invention, as hot air is continuously input into the drying cylinder, the air pressure inside the drying cylinder will increase. The hot air and water vapor extracted 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 towards the circular exhaust pipe. The hollow block will drive the grooved limiting plate to move. At this time, the exhaust spring will be stretched and deformed. When the strip 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 and not enter, avoiding the hot air leakage from affecting the drying and dehydration effect of the sludge.

[0024] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0036] 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.

[0037] Please see Figures 1-8 As shown, the present invention is a solid waste drying and treatment device, including a drying cylinder 1, and further comprising:

[0038] A turning mechanism is installed inside the drying cylinder 1. The turning mechanism includes a support frame 101 installed below the drying cylinder 1. The turning mechanism is used to continuously turn the sludge up during the drying process to increase the contact area between the sludge and the hot air.

[0039] The cleaning mechanism is installed inside the drying cylinder 1. The cleaning mechanism includes an arc-shaped groove 2 installed inside the drying cylinder 1. The cleaning mechanism is used to ensure the sealing of the drying cylinder 1 when drying sludge and to automatically open the drying cylinder 1 to discharge material after the drying work is completed.

[0040] An exhaust mechanism is installed on the drying cylinder 1. The exhaust mechanism includes an L-shaped hollow plate 3 installed inside the drying cylinder 1. The exhaust mechanism is used to clean the sludge at the exhaust port during the sludge drying process to prevent the sludge from solidifying and clogging the exhaust port after drying.

[0041] like Figure 2 As shown, the flipping mechanism includes two support plates 102 fixedly installed on the top of the support frame 101. Both support plates 102 are fixedly connected to the drying cylinder 1. A drive shaft 103 is rotatably installed inside the drying cylinder 1. A drive motor 104 is fixedly installed on the left side of the corresponding support plate 102. The output shaft of the drive motor 104 is fixedly connected to the drive shaft 103.

[0042] The drive motor 104 drives the drive shaft 103 to rotate, the drive shaft 103 drives several mounting brackets 105 to rotate, and the mounting brackets 105 drive the L-shaped plate 106 to rotate.

[0043] like Figure 3 As shown, a number of mounting brackets 105 are fixedly installed on the outer wall of the drive shaft 103. L-shaped plates 106 are fixedly installed on the ends of the mounting brackets 105 that are far apart from each other. Slots 107 are opened on the L-shaped plates 106 respectively.

[0044] When the L-shaped plate 106 and the trapezoidal plate 110 rotate, the sludge will be turned up by centrifugal force. When the L-shaped plate 106 drives the sludge to the highest point, the sludge will fall out of the strip groove 107 and return to the sludge in the drying cylinder 1 under the action of gravity.

[0045] like Figure 2 and Figure 5 As shown, hollow grooves 108 are respectively opened in several L-shaped plates 106. Several limiting springs 109 are fixedly installed on the inner walls of several hollow grooves 108. Trapezoidal plates 110 are fixedly installed at the ends of several limiting springs 109. Several trapezoidal plates 110 slide and extend to the outside of several hollow grooves 108 and contact the inner wall of the drying cylinder 1. A feed pipe 111 is fixedly installed at the top of the drying cylinder 1. A closing valve is provided on the feed pipe 111. An air inlet pipe 112 is fixedly installed on the left side of the drying cylinder 1. The air inlet pipe 112 communicates with the drying cylinder 1.

[0046] Correspondingly, some 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 also be stirred during the rotation of the L-shaped plate 106 and the trapezoidal plate 110, so that the sludge can fully contact the hot air and improve the drying and dehydration efficiency. During the rotation of the trapezoidal plate 110, it will contact the inner wall of the drying cylinder 1 and scrape the sludge on the inner wall of the drying cylinder 1 clean. This can prevent the sludge from sticking to the inner wall of the drying cylinder 1 after drying, avoid the device from jamming, and save the manual cleaning process of the inner wall of the drying cylinder 1.

[0047] like Figure 4 and Figure 5 As shown, the cleaning mechanism includes an arc-shaped groove 2 inside the drying cylinder 1. Several arc-shaped springs 201 are fixedly installed on the top inner wall of the arc-shaped groove 2. Arc-shaped closing plates 202 are fixedly installed at the bottom ends of the arc-shaped springs 201 respectively. The arc-shaped closing plates 202 are slidably connected to the arc-shaped groove 2. A rectangular locking block 203 is fixedly installed through the arc-shaped closing plate 202. A handle 204 is fixedly installed at the bottom end of the rectangular locking block 203.

[0048] 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 closed plate 202, the limiting spring 109 will contact the trapezoidal plate 110 with the arc-shaped closed plate 202 under the action of elasticity, ensuring that the sludge in the groove of the arc-shaped closed plate 202 will also be subjected to the stirring effect, further improving the overall drying of the sludge.

[0049] like Figure 6 As shown, a trapezoidal groove 205 is provided on the inner right side 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.

[0050] The cleaning plate 207 cleans the sludge that is 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, so as to prevent the sludge from clogging the strip chute 304 and affecting the normal discharge of gas in the drying cylinder 1.

[0051] like Figure 6 As shown, two cleaning springs 208 are sleeved on the bar 206. The ends of the two cleaning springs 208 that are far apart 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. Several oblique circular grooves 209 are opened on the cleaning plate 207.

[0052] The corresponding T-shaped arc block 302 will leave the L-shaped plate 106, and at this time, the cleaning plate 207 will sway left and right under the elastic force of the cleaning spring 208.

[0053] like Figure 6 As shown, the exhaust mechanism includes an L-shaped hollow plate 3 fixedly installed at the bottom of the drying cylinder 1. A telescopic spring 301 is fixedly installed on the inner right side of the L-shaped hollow plate 3. A T-shaped arc block 302 is fixedly installed at the left end of the telescopic spring 301. The left end of the T-shaped arc block 302 slides out of the L-shaped hollow plate 3.

[0054] During the rotation of the L-shaped plate 106, it will come into contact with the arc surface of the T-shaped arc block 302. Under the limiting effect of the arc surface and the friction, the L-shaped plate 106 will drive the T-shaped arc block 302 to move. At this time, the T-shaped arc block 302 will drive the cleaning plate 207 to move. The two cleaning springs 208 will undergo tensile deformation and compressive deformation respectively. After the L-shaped plate 106 drives the T-shaped arc block 302 to move a certain distance, when the elastic force of the cleaning spring 208 is greater than the friction force of the T-shaped arc block 302, the T-shaped arc block 302 will slide into the L-shaped hollow plate 3.

[0055] like Figure 8 As shown, a rectangular box 303 is fixedly installed on the right side of the drying cylinder 1. Several strip-shaped inclined grooves 304 are opened on the left side of the rectangular box 303. The rectangular box 303 is connected to the drying cylinder 1. Several circular exhaust pipes 305 are fixedly installed on the right side of the rectangular box 303. The several circular exhaust pipes 305 are connected to the rectangular box 303.

[0056] As hot air is continuously fed into the drying cylinder 1, the air pressure inside 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.

[0057] like Figure 7 and Figure 8 As shown, a grooved limiting plate 306 is slidably installed inside the rectangular box 303. Several hollow blocks 307 are fixedly installed on the right side of the grooved limiting plate 306. The front and back of the hollow blocks 307 are respectively provided with strip-shaped ventilation grooves. Two exhaust springs 308 are fixedly installed on the left side of the grooved limiting plate 306. The left ends of the two exhaust springs 308 are fixedly connected to the rectangular box 303.

[0058] At this time, the gas will push the hollow block 307 to move closer to the circular exhaust pipe 305. The hollow block 307 will drive the grooved limiting plate 306 to move. At this time, the exhaust spring 308 will undergo tensile deformation. When the strip-shaped ventilation 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 gas emission can be effectively controlled, so that the gas in the drying cylinder 1 can only be discharged and not enter, avoiding hot gas leakage from affecting the drying and dewatering effect of the sludge.

[0059] In operation, sludge is poured into the drying cylinder 1 through the feed pipe 111, ensuring the sludge level is no higher than the height of the drive shaft 103. Then, the drive motor 104 is started, and hot air is introduced into the drying cylinder 1 through the air inlet pipe 112. The drive motor 104 drives the drive shaft 103 to rotate, which in turn drives several mounting brackets 105 to rotate. The mounting brackets 105 then drive the L-shaped plate 106 to rotate. During rotation, the L-shaped plate 106 and the trapezoidal plate 110, under centrifugal force, tumble the sludge. When the L-shaped plate 106 carries the sludge to its highest point, the sludge, under gravity, falls out of the strip trough 107 and returns to the sludge inside the drying cylinder 1. Correspondingly, some 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 also be stirred during the rotation of the L-shaped plate 106 and the trapezoidal plate 110, so that the sludge can fully contact the hot air and improve the drying and dehydration efficiency. During the rotation of the trapezoidal plate 110, it will contact the inner wall of the drying cylinder 1 and scrape the sludge on the inner wall of the drying cylinder 1 clean. This can prevent the sludge from sticking to the inner wall of the drying cylinder 1 after drying, avoid the device from jamming, and save the manual cleaning process of the inner wall of the drying cylinder 1.

[0060] During the rotation of the trapezoidal plate 110, its inclined surface continuously contacts the rectangular clamping block 203. When the trapezoidal plate 110 enters the groove of the arc-shaped closed plate 202, the limiting spring 109, under the action of elastic force, will keep the trapezoidal plate 110 in contact with the arc-shaped closed plate 202, ensuring that the sludge in the groove of the arc-shaped closed plate 202 is also agitated, further improving the overall drying of the sludge. When the trapezoidal plate 110 contacts the rectangular clamping block 203, the trapezoidal plate 110 will slide into the hollow groove 108, and the corresponding limiting spring 109 will undergo compression deformation, ensuring that the trapezoidal plate 110... 10. The sludge passes smoothly through the rectangular clamp 203 and is continuously turned over. After the sludge is dried and dewatered, the drive motor 104 is rotated in the opposite direction. The drive motor 104 will drive the trapezoidal plate 110 to reverse. At this time, the plane of the trapezoidal plate 110 contacts the rectangular clamp 203. The rectangular clamp 203 will drive the arc-shaped closing plate 202 to open under the push of the trapezoidal plate 110. At this time, the automatic feeding effect can be achieved, while saving manpower. When the arc-shaped closing plate 202 opens, 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-shaped groove 2, further enhancing the self-cleaning effect.

[0061] During the rotation of the L-shaped plate 106, it will contact the arc surface of the T-shaped arc block 302. Under the limiting effect of the arc surface and friction, the L-shaped plate 106 will drive the T-shaped arc block 302 to move. At this time, the T-shaped arc block 302 will drive the cleaning plate 207 to move. Correspondingly, the two cleaning springs 208 will undergo tensile deformation and compressive deformation respectively. After the L-shaped plate 106 drives the T-shaped arc block 302 to move a certain distance, when the elastic force of the cleaning spring 208 is greater than the frictional force of the T-shaped arc block 302, the T-shaped arc block... 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, under the elastic force of the cleaning spring 208, the cleaning plate 207 will sway left and right. The cleaning plate 207 will clean the sludge that is thrown onto the strip inclined chute 304 when the sludge is turned over. The cleaned sludge will fall into the drying cylinder 1 from the trapezoidal groove 205, so as to avoid the sludge blocking the strip inclined chute 304 and affecting the normal discharge of gas in the drying cylinder 1.

[0062] As hot air is continuously fed into the drying cylinder 1, the air pressure inside the drying cylinder 1 increases. The hot air and water vapor extracted from the sludge enter the rectangular box 303 through the strip-shaped inclined groove 304. At this time, the gas pushes the hollow block 307 to move closer to the circular exhaust pipe 305. The hollow block 307 drives the grooved limiting plate 306 to move. At this time, the exhaust spring 308 will undergo tensile deformation. When the strip-shaped 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 gas discharge can be effectively controlled, so that the gas in the drying cylinder 1 can only be discharged and not enter, avoiding hot air leakage that affects the drying and dewatering effect of the sludge.
