DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model are clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example 1
[0023] Please see attached Figure 1-7 , the present embodiment is a lime slurry drying device: it includes a bracket 1, the bracket 1 is rotatably connected to a drying cylinder 2, the drying cylinder 2 is provided with a feed port and a discharge port, the feed port is provided with a water screening hopper 3, the lower end of the water screening hopper 3 is matched with a first water collecting trough 4, the water screening hopper 3 and the first water collecting trough 4 are both fixedly connected to the bracket 1, the bracket 1 is provided with a discharge plate 5, the discharge plate 5 is located at the lower end of the discharge port, the water screening hopper 3 includes a sieve plate 301, the sieve plate 301 is tilted, a plurality of sieve holes 302 distributed at equal intervals are opened on the sieve plate 301, the sieve plate 301 on the side of the sieve hole 302 is provided with a guide groove 303, and the upper end of the sieve plate 301 is fixedly connected to a guard plate 304.
[0024] The drying drum 2 is a hollow cylinder structure. The lime slurry enters the drying drum 2 from the feed port. The drying drum 2 can rotate on the bracket 1 to evenly arrange the lime slurry on the inner wall of the drying drum 2. The dried lime powder falls from the discharge port onto the discharge plate 5. The discharge plate 5 is used to collect the dried lime powder. In order to facilitate the lime slurry to enter the drying drum 2, a water screening hopper 3 is installed at the feed port of the drying drum 2. A plurality of sieve holes 302 are provided at the bottom of the water screening hopper 3. The water in the lime slurry falls from the sieve holes 302. The first water collecting tank 4 at the lower end of the water screening hopper 3 is used to collect the water in the lime slurry, which is convenient for the lime slurry to be collected later. The separated liquid is processed; in order to facilitate the lime slurry to enter the drying cylinder 2, an inclined sieve plate 301 is provided at the bottom of the water screening hopper 3. Under the action of gravity, the inclined sieve plate 301 facilitates the flow of the lime slurry. The guide groove 303 on the sieve plate 301 is recessed downward relative to the sieve plate 301. The viscous slurry in the lime slurry falls into the guide groove 303 under the action of gravity, and the water in the upper layer of the lime slurry falls into the first collecting tank under the action of the sieve hole 302, so that the water screening hopper 3 performs a one-step water removal process on the lime slurry, thereby increasing the viscosity of the lime slurry entering the drying cylinder 2 and improving the discharge efficiency of the drying cylinder 2.
[0025] Four driving rollers 6 are provided on the bracket 1, and two driving rollers 6 are provided on the left and right sides of the drying cylinder 2. The driving rollers 6 are frictionally connected with the friction sleeve 7. The friction sleeve 7 increases the wear resistance of the drying cylinder 2 and improves the service life of the device. In order to further improve the drying efficiency of the drying cylinder 2, small leakage holes are provided on the drying cylinder 2. The rotating centrifugal force of the drying cylinder 2 can throw out the liquid in the lime slurry to improve the drying effect. The thrown water is collected by the second water collecting tank 8 at the lower end. A protective cover is provided at the outer end of the drying cylinder 2, and a heating device for heating the drying cylinder 2 is provided in the protective cover.
[0026] The connecting block 9 of the discharge port is a truncated cone structure, and the purpose of the connecting block 9 is to reduce the diameter of the discharge port. The diameter of the through hole 10 is smaller than the width of the discharge plate 5 to ensure that the lime coming out of the through hole 10 can fall onto the discharge plate 5. Example 2
[0027] The structure of this embodiment is the same as that of the above-mentioned embodiment, but the specific difference of this embodiment is that a vibrator 11 is fixedly connected to the bottom of the discharge plate 5 , and a rebounder is installed between the discharge plate 5 and the bracket 1 .
[0028] In order to facilitate the falling of lime from the discharge plate 5, the discharge plate 5 is placed at an angle. Furthermore, a grid hole can be provided on the discharge plate 5. A vibrator 11 is installed at the bottom of the discharge plate 5. The vibrator 11 can make the discharge plate 5 vibrate. The vibrator 11 cooperates with the rebounder to increase the vibration frequency of the discharge plate 5. On the one hand, it is convenient for the lime to fall from the discharge plate 5. On the other hand, the block lime and powder lime can be screened and collected through the grid holes on the discharge plate 5.
[0029] The rebounder includes a first connecting rod 12 and a second connecting rod 13, the first connecting rod 12 is fixedly connected to the discharge plate 5, the second connecting rod 13 is fixedly connected to the bracket 1, the first connecting rod 12 and the second connecting rod 13 are slidably connected, a baffle 14 is fixedly connected to the second connecting rod 13, a spring 15 is sleeved on the second connecting rod 13 on the upper side of the baffle 14, the spring 15 has a downward elastic force on the second connecting rod 13, and the spring 15 has an upward elastic force on the first connecting rod 12, so that the rebound ability of the discharge plate 5 is improved under the action of the elastic deformation of the spring 15.
