Description

Technical Field

[0001] The utility model relates to the technical field of drying machine cleaning, in particular to a sludge drying machine. Background Art

[0002] Sludge is a solid sediment produced by the water and sewage treatment process. With the strengthening of the country's energy conservation and emission reduction efforts, the improvement of national environmental protection awareness, and the increasing production of urban sludge, the issue of sludge disposal and development and utilization has become an important issue in the country's environmental protection work. The development of sludge drying treatment technology has made it possible to use sludge for agricultural purposes, sludge fuel, and sludge incineration. The improvement and innovation of sludge drying technology and sludge dryers have directly promoted the development of sludge disposal methods, expanded the range of sludge disposal methods, and made it more and more reliable in terms of safety, reliability, and sustainability.

[0003] During the use of the existing sludge dryer, the sludge enters the dryer through the chute via the feeder. As the drum rotates, the sludge is fed in a scattered spiral state during the continuous rotation. During the scattered spiral feeding with the rotation of the drum, the high-temperature airflow passes through and heats and evaporates the sludge, thereby drying the sludge. Since the sludge itself contains moisture, there is a problem of sludge adhering to the inner wall of the barrel and the spiral blades during the continuous drying process. The regular cleaning method of the transmission is manual, which is inefficient. In view of this, we propose a sludge dryer. Utility Model Content

Through the setting of the scraping and cleaning device 4, when it rotates synchronously with the dryer drum 2, the scraping and cleaning device 4 does not affect the drying of the thrown materials in the dryer drum 2. When the scraping and cleaning device 4 rotates alone, the connecting plate 43 on the rotating gear ring 41 is limitedly rolled on both sides of the annular curved track 45 in a fixed state through two rollers 44, thereby realizing the connection plate 43 The spiral blade 6 and the reinforced scraper 7 are driven by the rotating ring 5 to perform a linear reciprocating motion during the revolution, thereby improving the scraping effect of the spiral blade 6 and the reinforced scraper 7 on the drum arm, while increasing the shaking effect of the high-frequency motion of the spiral blade 6 and the reinforced scraper 7, and then using the vibration to drive the spiral blade 6 and the reinforced scraper 7 to discharge the sludge, thereby achieving the purpose of fully cleaning the residual sludge on the inner wall of the drum.

[0024] Furthermore, a roller 44 is rotatably connected inside the connecting plate 43 , and a circular curved track 45 is connected to the surface of the roller 44 . The circular curved track 45 is sleeved and fixed on the drying drum 2 .

[0025] Example 2

[0026] See also Figure 3As shown, the driving device 3 includes an active motor 31, one end of which is mounted on the machine base 1, the output shaft of the active motor 31 is connected to a driving tooth 32, the surface of the driving tooth 32 is meshed with a connecting tooth 33, the interior of the connecting tooth 33 is fixedly connected to a connecting shaft 34, one end of the connecting shaft 34 is fixedly connected to a cleaning tooth 35, the other end of the connecting shaft 34 is slidably connected to a drying tooth 36, the surface of the drying tooth 36 is meshed with a material transfer ring gear 37, by setting the driving device 3, when the drying tooth 36 is meshed with the material transfer ring gear 37, the active motor 31 meshes with the connecting tooth 33 on the connecting shaft 34 through the driving tooth 32, the connecting shaft 34 meshes with the cleaning tooth 35 and the drying tooth 36 to rotate the rotating gear ring 41 and the material transfer ring gear 37, and the drying drum 2 The spiral blade 6 and the reinforcement scraper 7 on the rotating ring 5 rotate synchronously, and then the effect of throwing and drying is achieved; when the drying teeth 36 are not engaged with the material transfer ring gear 37, only the rotating ring gear 41 rotates, and the connecting plate 43 is limitedly rolled on both sides of the annular curved track 45 in a fixed state through two rollers 44, and then the connecting plate 43 drives the spiral blade 6 and the reinforcement scraper 7 to perform linear reciprocating motion during the revolution through the rotating ring 5, while improving the scraping effect of the spiral blade 6 and the reinforcement scraper 7 on the cylinder arm, increasing the shaking effect of the high-frequency movement of the spiral blade 6 and the reinforcement scraper 7, and then using the vibration to drive the spiral blade 6 and the reinforcement scraper 7 to discharge the sludge, so as to achieve the purpose of fully cleaning the residual sludge on the inner wall of the cylinder. The surface of the connecting shaft 34 is rotatably connected to the base 1, the surface of the cleaning teeth 35 is engaged with the surface of the rotating ring gear 41, and the material transfer ring gear 37 is sleeved and fixed on the drying cylinder 2.

[0027] Furthermore, an adjusting motor 38 is installed on the machine base 1, and the output shaft of the adjusting motor 38 is connected to a screw 39, and the screw 39 is threadedly connected to a moving seat 310, and the end of the drying tooth 36 is rotatably connected to the moving seat 310. By setting the adjusting motor 38 to control the rotation of the screw 39, the effect of adjusting the position of the drying teeth 36 on the moving seat 310 is achieved, and then the change in the position of the drying teeth 36 is used to achieve the switching of the meshing and disengagement states of the material transfer gear ring 37, thereby controlling the switching of the rotating or non-rotating state of the barrel.

[0028] When the sludge dryer of the utility model is in use, the sludge is fed into the dryer cylinder 2 through the existing feeding mechanism. During the feeding period, the driving motor 31 is started to drive the driving gear 32 to mesh with the connecting gear 33 and the connecting shaft 34 to rotate as a whole. The connecting shaft 34 rotates by meshing the cleaning gear 35 and the drying gear 36 to rotate the rotating gear ring 41 and the material transfer gear ring 37. The rotating gear ring 41 and the material transfer gear ring 37 realize synchronous rotation. The material transfer gear ring 37 drives the dryer cylinder 2 to rotate as a whole through the force of the fixed connection, and the machine is realized during the rotation. The sludge fed into the drum is constantly rotating and turning, and the drying mechanism at this time injects high-temperature airflow into the drum to assist in drying. Since the rotating gear ring 41 and the material transfer gear ring 37 are in synchronous rotation, the connecting plate 43 on the guide rod 42 connected by the rotating gear ring 41 drives the spiral blades 6 on the rotating ring 5 and the reinforced scraper 7 as a whole to rotate relatively statically in the dryer drum 2. The spiral blades 6 are used to guide the constantly rotating and turning sludge. The sludge is spirally fed and dried during the continuous throwing period, and finally discharged from the other end of the dryer drum 2.

[0029] After the sludge is dried and discharged, the active motor 31 stops, and less sludge will remain inside the drying machine cylinder 2. At this time, the adjusting motor 38 is started, and the adjusting motor 38 rotates by driving the screw 39, and drives the movable seat 310 threadedly connected thereon and linearly limited thereon to move, and the movable seat 310 drives the drying teeth 36 to slide on the connecting shaft 34. After sliding, the drying teeth 36 are disengaged from the meshing with the material transfer gear ring 37. At this time, the active motor 31 is started, and the output shaft of the active motor 31 drives the connecting shaft 34 on the meshing connecting teeth 33 through the driving teeth 32. The cleaning teeth 35 rotate, and at this time only the cleaning teeth 35 mesh with the rotating gear ring 41 to drive the connecting plate 43 on the guide rod 42 to drive the rotating ring 5 to rotate as a whole. The dryer drum 2 is locked in the machine base 1 by the self-locking mechanism. The self-locking mechanism is any existing public technology that can fix the dryer drum 2, which is used to ensure the stability of the dryer drum 2 under normal conditions. During the rotation, the rotating ring 5 drives the spiral blades 6 and the reinforced scraper 7 to rotate as a whole. During the rotation, the spiral blades 6 and the reinforced scraper 7 achieve the effect of rotating and scraping the inner wall of the drum, and then can The sludge attached to the inner wall of the cylinder can be automatically cleaned. At the same time, due to the fixation of the drying cylinder 2, the annular curved track 45 is also in a fixed state. When the rotating gear ring 41 is rotating, the connecting plate 43 is affected by the rolling of the rollers 44 on both sides of the annular curved track 45 to continuously move in a straight line. The connecting plate 43 that continuously moves in a straight line while revolving on the guide rod 42 will drive the rotating ring 5 to move as a whole, thereby achieving the effect of the spiral blades 6 and the reinforcement scraper 7 performing a straight reciprocating motion during the revolution, thereby improving the cleaning effect. While the high spiral blades 6 and the reinforced scraper 7 have a scraping effect on the drum arm, the high-frequency movement of the spiral blades 6 and the reinforced scraper 7 deepens the shaking effect of the spiral blades 6 and the reinforced scraper 7 themselves, and then the vibration drives the spiral blades 6 and the reinforced scraper 7 to discharge the sludge, thereby achieving the purpose of fully cleaning the residual sludge on the inner wall of the drum. After the cleaning work is completed, the adjustment motor 38 can be started again to drive the screw 39 to adjust the position of the moving seat 310, so that the drying teeth 36 engage the material transfer gear ring 37 again, which is convenient for subsequent sludge drying work.

Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the embodiments of the present utility model.
