Technical Field

[0001] The utility model belongs to the technical field of drying devices, and specifically relates to a double-cone vacuum dryer. Background Technique

[0002] The working mechanism of the double-cone vacuum dryer is as follows: the material jacket in the tank is heated by a heat medium such as hot water, steam or heat-conducting oil, and the tank rotates slowly under the drive of a power mechanism, and the materials in the tank are continuously mixed to achieve the purpose of strengthening drying.

[0003] After retrieval, the document with the publication number (CN117647064A) discloses a double-cone vacuum dryer, which includes a frame. The side wall of the frame is rotatably connected with a tank. A vacuum filter is arranged inside the tank. The vacuum filter includes a connecting pipe. A protective component is sleeved on the outer side wall of the vacuum filter. The protective component includes a protective shell. A fixing component is arranged inside the protective shell. The fixing component corresponds to and cooperates with the vacuum filter.

[0004] The above device is provided with a protective component. The protective shell can protect the vacuum filter to avoid being deformed and bent by the rolling materials in the tank. And the semi-circular shell provided can effectively reduce the impact of the rolling materials in the tank on the protective shell when the tank rotates, thereby avoiding the deformation and bending of the protective shell, and further protecting the vacuum filter. And when the protective shell is impacted by the rolling materials in the tank, the convex plate and the vertical plate are both slidably connected to the sliding ring. Therefore, the protective shell can be rotated to unload the force and provide secondary protection for the protective shell.

[0005] When loading materials into the above device, the materials need to be screened first. At present, most of the screening steps are carried out with the help of other devices, resulting in the need to transport the materials twice after screening, increasing the processing steps.

[0006] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0007] To solve the technical problem of material screening, the basic concept of the technical solution adopted by the present utility model is as follows:

[0008] A double-cone vacuum dryer includes a bracket composed of two symmetric columns; a drying cylinder arranged in the middle of the bracket and rotatably connected to the bracket; a vacuum component arranged between the bracket and the drying cylinder for vacuum filtering the materials in the drying cylinder; a screening component arranged on the bracket for screening the materials. The screening component includes a first shovel and a second shovel. The first shovel is arranged on the bracket and is in transmission connection with the bracket. The second shovel is arranged at the bottom end of the first shovel and is fixedly connected to the bracket.

[0009] As a preferred embodiment of the present utility model, the first bucket is integrally trapezoidal, a screening net is installed at the opening end of the first bucket through fasteners, and the opening of the second bucket is located at the upper end of the drying cylinder.

[0010] As a preferred embodiment of the present utility model, the screening assembly further includes a mounting frame, the mounting frame is arranged on the support, the mounting frame and the support are connected by fasteners, and the first bucket is fixedly connected to the mounting frame.

[0011] As a preferred embodiment of the present utility model, the screening assembly further includes spring plates, multiple groups of spring plates are arranged on the mounting frame, the spring plates are fixedly connected to the mounting frame, and the first bucket is fixedly connected to the spring plates.

[0012] As a preferred embodiment of the present utility model, an eccentric motor is arranged between the mounting frame and the spring plate, the eccentric motor is fixedly connected to the mounting frame, and the output shaft of the eccentric motor abuts against the spring plate.

[0013] As a preferred embodiment of the present utility model, the screening assembly further includes a third bucket, the third bucket is arranged between the first bucket and the second bucket, one end of the third bucket is located at the opening position of the first bucket, the opening position of the third bucket is on the support, and the third bucket is fixedly connected to the support.

[0014] As a preferred embodiment of the present utility model, the first bucket, the second bucket and the third bucket are all integrally trapezoidal, and the opening directions of the first bucket, the second bucket and the third bucket are the same.

[0015] As a preferred embodiment of the present utility model, the vacuum assembly includes a connecting shaft, a double-headed pipe and a vacuum filter, the connecting shaft is fixedly connected to the support, the connecting shaft is rotationally connected to the drying cylinder, the double-headed pipe is fixedly connected to one end of the connecting shaft, and the vacuum filter is fixedly connected to both ends of the double-headed pipe.

[0016] The present utility model has the following beneficial effects compared with the prior art:

[0017] 1. For this double-cone vacuum dryer, the screened material enters the second bucket through the screening net at the opening of the first bucket. Due to the inclined setting of the second bucket, the material enters the drying cylinder through the inclination angle of the second bucket. Through the cooperation of the first bucket and the second bucket, the material is screened, so that the screened material enters the drying cylinder, reducing the operation steps and improving the work efficiency.

[0018] 2. For this double-cone vacuum dryer, when the eccentric motor rotates through the output shaft, it abuts against and drives the spring plate. The spring plate is driven to vibrate. Due to its own elasticity, the amplitude of vibration of the spring plate is larger than that of rigid plates and other materials. However, the spring plate is limited by the eccentric motor and the second bucket, resulting in a limited amplitude of vibration. But the force on the spring plate still exists. Therefore, the amplitude of vibration is converted into the frequency of vibration, thereby increasing the vibration frequency of the spring plate driving the first bucket and improving the screening effect.

[0019] 3. For this double-cone vacuum dryer, the unqualified materials at the screening area enter the third bucket through the opening of the first bucket, and the third bucket discharges the unqualified materials, avoiding the accumulation of materials on the first bucket, which may affect the material screening or cause too much material to accumulate and enter the drying cylinder.

[0020] 4. For this double-cone vacuum dryer, when the drying cylinder rotates, it contacts the vacuum filters at both ends. The vacuum filters act as stirring rods, stirring the materials in the drying cylinder to make the materials mix more evenly. After mixing for an appropriate time, the vacuum machine conducts vacuum treatment on the inside through the vacuum filters and the double-headed pipe.

The following embodiments are used to illustrate the present invention.

A motor and a heating pipe are installed in the bracket 1, and the drying cylinder 11 is driven to rotate by the output shaft of the motor. The heating pipe provides heat for the drying cylinder 11. The motor and the heating pipe are prior art, so they are not drawn in the figure. The double-cone vacuum dryer disclosed in the document with publication number CN117647064A has been fully disclosed, and will not be repeated here; a vacuum component, which is arranged between the bracket 1 and the drying cylinder 11 The vacuum component is used for vacuum filtering the material in the drying cylinder 11; the screening component is arranged on the bracket 1, and the screening component is used for screening the material. The screening component includes a first bucket 21 and a second bucket 22. The first bucket 21 is arranged on the bracket 1, and the first bucket 21 is transmission-connected to the bracket 1. The second bucket 22 is arranged at the bottom of the first bucket 21, and the second bucket 22 is fixedly connected to the bracket 1. The second bucket 22 is tilted. The material is screened by the cooperation of the first bucket 21 and the second bucket 22, so that the screened material directly enters the drying cylinder 11, thereby reducing the operation steps and improving the work efficiency.

[0031] Among them, the first bucket 21 is trapezoidal as a whole. A screening mesh is installed at the open end of the first bucket 21 through fasteners. The fasteners include but are not limited to bolts. The opening of the second bucket 22 is located at the upper end of the drying cylinder 11. The screening assembly further includes a mounting frame 2. The mounting frame 2 is arranged on the support 1. The mounting frame 2 and the support 1 are connected by fasteners. The fasteners include but are not limited to bolts. The first bucket 21 is fixedly connected to the mounting frame 2. The screening assembly further includes spring plates 24. A plurality of groups of spring plates 24 are arranged on the mounting frame 2. The spring plates 24 are fixedly connected to the mounting frame 2. The first bucket 21 is fixedly connected to the spring plates 24. An eccentric motor is arranged between the mounting frame 2 and the spring plates 24. The eccentric motor is fixedly connected to the mounting frame 2. The output shaft of the eccentric motor abuts against the spring plates 24. The screening assembly further includes a third bucket 23. The third bucket 23 is arranged between the first bucket 21 and the second bucket 22. One end of the third bucket 23 is located at the opening position of the first bucket 21. The opening position of the third bucket 23 is located on the support 1. The third bucket 23 is fixedly connected to the support 1. The first bucket 21, the second bucket 22 and the third bucket 23 are all trapezoidal as a whole. The opening directions of the first bucket 21, the second bucket 22 and the third bucket 23 are the same. When the eccentric motor rotates through the output shaft, it abuts against and drives the spring plates 24. The spring plates 24 are driven to vibrate. Due to the elasticity of the spring plates 24 themselves, the swing amplitude is larger than that of materials such as rigid plates. However, the spring plates 24 are limited by the eccentric motor and the second bucket 22, resulting in the swing amplitude being limited. However, the force on the spring plates 24 still exists. Therefore, the swing amplitude is converted into a swing frequency, thereby increasing the vibration frequency of the spring plates 24 driving the first bucket 21 and improving the screening effect. The screened materials enter the second bucket 22 through the screening mesh at the opening of the first bucket 21. Due to the inclined setting of the second bucket 22, the materials enter the drying cylinder 11 through the inclination angle of the second bucket 22. Through the cooperation of the first bucket 21 and the second bucket 22, the materials are screened, so that the screened materials directly enter the drying cylinder 11, reducing the operation steps and improving the work efficiency. The unqualified materials screened out enter the third bucket 23 through the opening of the first bucket 21, and the unqualified materials are discharged through the third bucket 23, avoiding the accumulation of materials on the first bucket 21, which may affect the material screening or cause too much material to accumulate and enter the drying cylinder 11.

[0032] Among them, the vacuum assembly includes a connecting shaft 3, a double-headed pipe 31 and a vacuum filter 32. The connecting shaft 3 is fixedly connected to the support 1. The connecting shaft 3 is rotatably connected to the drying cylinder 11. The double-headed pipe 31 is fixedly connected to one end of the connecting shaft 3. The vacuum filter 32 is fixedly connected to both ends of the double-headed pipe 31. The connecting shaft 3 is connected to a vacuum machine through a pipeline. When the drying cylinder 11 rotates, it contacts the vacuum filters 32 at both ends. The vacuum filters 32 act as stirring rods. The vacuum filters 32 stir the materials in the drying cylinder 11 to make the materials mix more evenly. After mixing for an appropriate time, the vacuum machine performs vacuum treatment on the inside through the vacuum filters 32 and the double-headed pipe 31.

[0033] Working principle: When the eccentric motor rotates through the output shaft, it abuts against and drives the spring plate 24. The spring plate 24 is driven to vibrate. Due to its own elasticity, the swing amplitude of the spring plate 24 is larger than that of materials such as rigid plates. However, the swing amplitude of the spring plate 24 is restricted by the eccentric motor and the second bucket 22. Although the force on the spring plate 24 still exists, the swing amplitude is converted into a swing frequency, thereby increasing the vibration frequency of the spring plate 24 driving the first bucket 21 and improving the screening effect. The screened materials enter the second bucket 22 through the screening mesh at the opening of the first bucket 21. Due to the inclined setting of the second bucket 22, the materials enter the drying cylinder 11 through the inclined angle of the second bucket 22. Through the cooperation of the first bucket 21 and the second bucket 22, the materials are screened, so that the screened materials directly enter the drying cylinder 11, reducing the operation steps and improving the work efficiency. The unqualified materials are discharged through the opening of the first bucket 21 into the third bucket 23, and the unqualified materials are discharged through the third bucket 23, avoiding the accumulation of materials on the first bucket 21, which may affect the material screening or cause too much material to enter the drying cylinder 11. When the drying cylinder 11 rotates, it contacts the vacuum filters 32 at both ends. The vacuum filters 32 act as stirring rods, and the vacuum filters 32 stir the materials in the drying cylinder 11 to make the materials mix more evenly. After mixing for an appropriate time, the vacuum machine performs vacuum treatment on the inside through the vacuum filters 32 and the double-headed pipe 31.
