[0002] The double-cone dryer is a drying device widely used in industries such as chemical industry, pharmacy, and food. It is suitable for drying powdery, granular, and fibrous materials, and is especially suitable for drying materials that are easy to oxidize, volatile, heat-sensitive, toxic, and materials that do not allow the destruction of crystals.
[0003] In the double-cone dryer, a heat source (such as hot water, low-pressure steam, or heat-conducting oil) is introduced into the closed sandwich layer, and the heat is transferred to the material to be dried through the inner shell. The tank body rotates slowly under the drive of power, so that the materials are continuously mixed, strengthening the drying effect. Under the vacuum state, the vapor pressure of the materials drops. After the moisture on the surface of the materials reaches the saturated state, it evaporates and is discharged and recycled by the vacuum pump to achieve rapid drying.
[0004] During the drying process, it is often necessary to put the materials and grinding balls into the tank body together. When discharging materials, the large-sized grinding balls and materials are sometimes mixed and may block the inlet and outlet, and manual dredging is required, which brings inconvenience to the staff.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The technical solution of the present utility model will be further described in detail below in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work belong to the scope of protection of the present utility model.
[0023] Please refer to Figures 1-3 , the present utility model provides a technical solution: a double-cone dryer, including a frame 1 and a double-cone rotary drum 2, wherein the double-cone rotary drum 2 is mounted on the frame 1, the upper and lower conical parts of the double-cone rotary drum 2 are material inlets and outlets, and holes for external pipelines to pass through are provided on both the left and right sides. The double-cone rotary drum 2 is a hollow structure and a flow channel 21 is provided on the drum wall. A sieve plate 22 is arranged in the middle of the double-cone rotary drum 2. Several springs 23 are connected to the periphery of the sieve plate 22. One end of the spring 23 is fixed to the inner wall of the double-cone rotary drum 2, and a tensile force sensing module 24 is arranged at the connection between the spring 23 and the inner wall of the double-cone rotary drum 2.
[0024] The supplementary description of the above structure is as follows: The sieve plate 22 is used to separate the grinding balls and materials put in. Due to the elasticity of the spring 23, under the impact of the grinding balls, the sieve plate 22 will be driven to vibrate by a certain amplitude, so as to effectively shake off the materials attached to the plate surface. The tensile force sensing module 24 can judge which space the grinding balls are in according to the detected tensile force brought by the sieve plate 22, so as to judge the position of the discharge port.
[0025] A number of sieve holes 221 are provided on the sieve plate 22, and the diameter width of the sieve holes 221 is smaller than the diameter width of the grinding balls to be put in. It should be added that: the sieve holes 221 of the sieve plate 22 are used to disperse and screen the materials and intercept the grinding balls. The grinding balls will always be in the area above or below the sieve plate 22, which is convenient for separation during discharging and prevents material blockage at the discharge port.
[0026] The flow channel 21 includes a hot flow channel 211 and a cold flow channel 212. Among them, the hot flow channel 211 is located inside the cold flow channel 212. A partition plate 213 is fixed between the hot flow channel 211 and the cold flow channel 212. A flow plate 214 is arranged at the interface between the hot flow channel 211 and the cold flow channel 212.
[0027] A number of air ports are provided on the flow plate 214.
[0028] Inclined fins 215 are arranged on the side wall surfaces of both sides of the hot flow channel 211.
[0029] The supplementary description of the above structure is as follows: After the hot fluid enters the hot flow channel 211, it is transferred to the cold flow channel 212 through the air ports on the flow plate 214. Among them, the fins 215 are used to increase the heat exchange area and extend the flow length of the hot fluid so as to complete heat exchange.
[0030] One side of the double-cone rotating cylinder 2 is connected to a first pipeline 3. One end of the first pipeline 3 extending into the double-cone rotating cylinder 2 is connected to a sieve cylinder 31, and the end of the first pipeline 3 extending out of the double-cone rotating cylinder 2 is connected to a vacuum pump 32. The vacuum pump 32 is used to discharge the air in the double-cone rotating cylinder 2 to create a vacuum state to improve the drying quality.
[0031] A rotating sleeve 33 is sleeved on the first pipeline 3. The rotating sleeve 33 is fixedly connected to the outer wall of the double-cone rotating cylinder 2. The rotating sleeve 33 is connected to a speed reducer 4 and a motor 5 through belt pulleys. The motor 5 is used to drive the double-cone rotating cylinder 2 to rotate so as to be heated evenly.
[0032] The other side of the double-cone rotating cylinder 2 is connected to a second pipeline 6. A third pipeline 7 is sleeved outside the second pipeline 6. One end of the second pipeline 6 communicates with the hot runner 211, and the other end is connected to a hot fluid tank 8. One end of the third pipeline 7 communicates with the cold runner 212, and the other end is connected to a cold fluid tank 9.
[0033] Working principle: First, open one end opening of the double-cone rotating cylinder 2, pour the material and the grinding balls together, and then seal it. The double-cone rotating cylinder 2 discharges the internal gas through the vacuum pump 32, and the sieve cylinder 31 is used to prevent the internal material from being discharged. The hot fluid is transported to the hot runner 211 through the hot fluid tank 8. At the same time, the motor 5 drives the double-cone rotating cylinder 2 to rotate through the rotating sleeve 33. During the process that the hot fluid passes through the hot runner 211, it exchanges heat with the inner wall of the double-cone rotating cylinder 2. After the heat exchange, the hot fluid is converted into a cold fluid and is output to the cold fluid tank 9 from the cold runner 212;
[0034] During the rotation of the double-cone rotating cylinder 2, the material is scattered and sieved through the sieve plate 22, making the heating more sufficient and uniform. The grinding balls are always located in the space above or below the sieve plate 22. When the drying is completed, the tensile force sensing module 24 detects the magnitude of the tensile force. The space where the grinding balls are located brings a greater pressure to the sieve plate 22. Based on this, the space where the grinding balls are located is turned upwards, and then the double-cone rotating cylinder 2 is driven to deflect at a certain angle to sieve out the residual material on the sieve plate 22, and the dried material is taken out by opening the lower opening.
[0035] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
