The top of the left end of the shell 1 is provided with a material inlet 11, the feeding mode of the dryer adopts belt conveying or reamer conveying, as shown in fig. 3, a belt conveying feeder 7 is matched with the material inlet 11 of the shell 1, and materials are conveyed into the dryer; a material outlet 12 is arranged on one side wall of the right end of the shell 1. The bottom of the left end of the shell 1 is provided with an air inlet 13, and the air inlet 13 is connected with an air outlet of the fan 5. The inside of the shell 1 is provided with a semicircular hole plate I14 with a semicircular section below the rotating shaft 2 and the blade assembly 3, and the central axis of the rotating shaft 2 is arranged at the center of the circle above the semicircular hole plate I14. The housing 1 is provided with an air duct 16 below the first orifice plate 14. The first orifice plate 14 extends from left to right to penetrate through the whole shell 1, the first orifice plate 14 is uniformly perforated, and the aperture ratio is 25%, so that the air quantity of each part is uniform when the first orifice plate 14 is ventilated upwards. Except for the material inlet 11, a second orifice plate 15 is covered at the top opening of the shell 1, and the aperture ratio of the second orifice plate 15 can reach 50%, so that the moisture is discharged.
The speed reducer 4 is arranged on the right side of the shell 1, and the speed reducer 4 is in transmission connection with the rotating shaft 2 through the coupler 41 and is used for driving the rotating shaft 2 to rotate.
The fan 5 and the heat source 6 are arranged on the left side of the shell 1, and the fan 5 and the heat source 6 are assembled together and used for providing hot air for the dryer. In this embodiment, the heat source 6 is an electric heating tube set. The fan 5 adopts a medium-pressure fan, and the material filled in the dryer is basically full and accounts for more than 90% of the whole volume, so that the medium-pressure fan is convenient for penetrating the material.
The paddle assembly 3 is used for turning and pushing materials, the paddle assembly 3 is arranged in a staggered mode along the axial direction of the rotating shaft 2, the interval between the paddle assemblies 3 is 300mm, and the paddle assembly 3 comprises a paddle shaft 31 and paddles connected with the paddle shaft 31. The paddles include a first paddle 32 and a second paddle 33. As shown in fig. 3, the projections of the adjacent three blade assemblies 3 arranged on the rotating shaft 2 on the same plane are shown, and the included angle between the adjacent two blade shafts 31 is 120 degrees. In the continuous rotation process, the paddles on the rotating shaft 2 dial materials outwards from the material outlet 12, and a conveying belt can be arranged at the material outlet 12 to output dry materials to a position farther away.
The first paddle 32 is mainly used for turning materials so that the materials in the dryer are uniformly dried, and the second paddle 33 is mainly used for pushing the materials forwards; the first paddle 32 and the second paddle 33 each include a body portion 322 and a tip portion 321 disposed at one end of the body portion 322, and the size of the body portion 322 is larger than the size of the tip portion 321. One end of the paddle shaft 31 is fixed on the rotating shaft 2, and the first paddle 32 and the second paddle 33 are mounted at the other end of the paddle shaft 31, specifically, edges of one sides of the first paddle 32 and the second paddle 33 are connected to the other end of the paddle shaft 31 by welding; the length of the first blade 32 extending along the blade axis 31 is smaller than the length of the second blade 33 extending along the blade axis 31, and the width of the first blade 32 is also smaller than the width of the second blade 33.
As shown in fig. 4, a plane B is set, the plane B is perpendicular to the central axis of the rotating shaft 2, the blade shaft 31 is located in the plane B, the first blade 32 is located at the left side of the plane B and forms an included angle with the plane B of 45-60 degrees, preferably, the first blade 32 forms an included angle with the plane B of 60 degrees; the second blade 33 is located on the right side of the plane B and at an angle of 20-30 degrees to the plane B, preferably at an angle of 30 degrees to the plane B, so that a sharp angle C is formed at the edge of the one side of the first blade 32, the second blade 33, which is connected to the shaft 2, which sharp angle C reduces the resistance of the blade to rotation.
The first paddle 32 has smaller size and larger included angle with the plane B, so that the resistance of the first paddle 32 to turn over the material is smaller, and the material is more convenient to turn over; the second paddle 33 is larger in size and smaller in included angle with the plane B, so that the resistance of pushing materials by the second paddle 33 is smaller, the materials can be pushed forward more conveniently, and the materials in the whole dryer can be gradually turned and move forward under the turning and pushing actions of the paddles all the time.
More specifically, as shown in fig. 5, in the process of turning and pushing the paddles, in order to further reduce the resistance of the materials, in design, the paddle shaft 31 is bent into an arc shape, the first paddle 32 and the second paddle 33 are both fan-shaped, the tips 321 of the two paddles form a certain angle with the paddle shaft 32, and the tips 321 of the two paddles are combined together to form a plow shape, so that the resistance of the rotation of the paddles is better reduced.
When the invention is used, the height of the materials in the dryer shell 1 is 200mm higher than the highest point of the blade, the top of the dryer shell 1 is covered by the orifice plate II 15 except the material inlet 11, the aperture ratio of the orifice plate II 15 can reach 50%, and the function of discharging the moisture is mainly played. Because some materials have dust which can leak into the air duct 16 below the first orifice plate 14 from the first orifice plate 14 at the bottom, the dust is blown to one end of the housing 1 away from the fan 5 under the action of wind, so that the housing 1 is provided with an openable slag removal door (not shown) at the tail end of the air duct 16, and the accumulated dust is conveniently removed.
The turning pushing paddle dryer of the invention has the following characteristics: 1. the dryer has simple structure, convenient manufacture, almost no fault point and safe and reliable use; 2. the loading volume rate is 90%, the machine is small, and the yield is high; 3. the first 14 air homogenizing holes of the orifice plate with the aperture ratio of 25% are skillfully utilized to uniformly ventilate the front and back of the dryer; 4. the special blade design ensures that the materials are slowly pushed while being turned over; 5. the bending design of the blade shaft and the fan-shaped design of the blade reduce the resistance of turning and pushing materials; 6. the invention has wide application, and granular materials, flaky materials, small section materials, agricultural product accessories, grains, chinese medicinal materials, feeds and fertilizers can be dried by adopting the turning pushing paddle dryer.
The above description of the embodiments of the present invention, which is not related to the present invention, belongs to the technology known in the art, and may be implemented with reference to the technology known in the art.
