Description

Technical Field

[0001] The present application relates to the field of drying, and in particular to a material drying device. Background Art

[0002] Xanthate and black powder are two common mineral processing agents. The preparation process of this type of mineral processing agent is generally as follows: raw materials are mixed and reacted to form powdery finished products, the powdery finished products are extruded and granulated, qualified particles are sent to the pellet drying process to remove the contained moisture, and the pellets are cooled and inspected for qualified storage. At present, in the preparation of xanthate and black powder, the pellet drying process generally uses a double cone dryer to remove moisture from solid pellets.

[0003] For related technologies, reference may be made to Chinese patent publication number CN104315817A, which discloses a double-cone dryer capable of preventing material agglomeration, including a support base and an oven rotatably mounted on the support base, wherein the oven is mainly composed of a double-cone-shaped jacket body and an outer cylinder body which are fixedly connected to each other to form a closed cavity, wherein the outer cylinder body is mounted on the support base through a pair of rotating shafts on its outer wall, a raw material inlet and outlet are provided on the jacket body, and a crushing device is provided on the inner wall of the jacket body at the inner end side of the rotating shaft, wherein the crushing device is in the shape of comb teeth and circumferentially erected on the inner wall of the jacket body; while the material is being rotated and dried, the material can actively impact the crushing pieces through the rotating rolling of the material to prevent the formation of agglomerates.

[0004] With regard to the above-mentioned related technologies, during the rotation of the double-cone dryer, the two conical ends of the oven cyclically move to the bottom alternately. At this time, the material will gather at the sealing cover under the action of gravity. However, since the sealing cover does not have a closed cavity for heating, the heating effect of the sealing cover on the material is not good, which affects the drying efficiency of the material. Summary of the invention

[0005] In order to improve the drying efficiency of materials, the present application provides a material drying device.

[0006] The present application provides a material drying device, which adopts the following technical solution:

[0007] A material drying device comprises a support frame and an oven, wherein the middle position in the length direction of the oven is rotatably connected to the support frame, the ends in the length direction of the oven are connected to a feeding pipe, the feeding pipe is hinged with a sealing cover, a first heating chamber is provided on the side wall of the oven, a partition is movably connected in the feeding pipe, the partition has a closed state for closing the feeding pipe and an open state for connecting the two ends of the feeding pipe, a second heating chamber is provided in the partition, and a connecting pipe for connecting the first heating chamber with the second heating chamber is provided in the oven.

[0008] By adopting the above technical solution, when adding materials, the user opens the sealing cover and controls the movement of the partition, switches the partition to an open state, and then adds materials into the oven. After the materials are added, the user switches the partition to a closed state and closes the sealing cover, and then uses the hot fluid to enter the first heating chamber for heating and drying. The hot fluid can enter the second heating chamber from the connecting pipe. Even if the materials are gathered at a position close to the sealing cover, the hot fluid in the second heating chamber can still have a better drying effect on the materials, and the drying efficiency of the materials is high.

[0009] Optionally, the connecting pipe is arranged along the radial direction of the partition, one end of the connecting pipe is rotatably connected to the oven, and the other end extends into the second heating chamber and is fixedly connected to the partition.

[0010] By adopting the above technical solution, the partition is rotatably connected to the feeding pipe by means of a connecting pipe. When the partition is at the radial cross-section of the feeding pipe, the partition is in a closed state, and the material is not easy to fall back into the feeding pipe; when the partition is rotated to separate from the radial cross-section of the feeding pipe, the partition is in an open state. The structure is simple and the two states of the partition can be switched more conveniently.

[0011] Optionally, a torsion spring is connected between the partition and the oven. When the torsion spring is in a natural state, the partition is in a closed state. A first connecting rope is connected between the partition and the corresponding sealing cover. The first connecting rope is fixedly connected to the eccentric position of the partition.

[0012] By adopting the above technical solution, when the user opens the sealing cover, the first connecting rope pulls the partition to automatically rotate to the open state; when the user closes the sealing cover, the tension of the first connecting rope disappears, and the partition automatically returns to the closed state under the elastic recovery force of the torsion spring. The structure is simple and does not require manual switching of the state of the partition, so it is easy to use.

[0013] Optionally, both ends of the oven in the length direction are tapered, and the diameter gradually decreases in the direction away from each other. The partition and the feed pipe are coaxially arranged, and guide rails are provided at both ends of the length direction of the oven. The partition is slidably connected to the guide rails along the length direction of the oven, and the connecting pipe is slidably connected to the partition along the radial direction of the partition, and the feed pipe is provided with a connecting hole connected to the first heating chamber.

[0014] By adopting the above technical solution, when the partition slides along the guide rail to the outside of the feeding pipe, it can enter the open state, and a gap will appear between the partition and the inner wall of the oven, and the material can enter the oven through the gap; on the contrary, when the partition is located in the feeding pipe, it is within the diameter section of the feeding pipe and enters the closed state, and the connecting pipe is inserted into the connecting hole, which is convenient for the hot fluid to enter the second heating chamber; the structure is simple and the two states of the partition can be switched more conveniently.

[0015] Optionally, a first baffle plate hinged to the oven is provided at the connection hole, a first elastic member is provided at the hinge between the first baffle plate and the oven, the first baffle plate closes the connection hole when the first elastic member is in a natural state, and a slope is provided on one side of the first baffle plate close to the feeding pipe.

[0016] By adopting the above technical solution, when adding materials, the connecting pipe is outside the connecting hole. At this time, the first baffle closes the connecting hole under the action of the first elastic member, and the material is not easy to accidentally fall into the first heating chamber through the connecting hole, thereby achieving a better use effect.

[0017] Optionally, a second elastic member is connected between the connecting tube and the partition. When the second elastic member is in a natural state, one end of the connecting tube extends outside the partition, and the end of the connecting tube away from the partition is provided with a conical portion with a smaller diameter. When the connecting tube is inserted into the connecting hole, the conical portion abuts against the hole wall of the connecting hole.

[0018] By adopting the above technical solution, when the user controls the partition to move away from the feeding pipe, the connecting pipe is gradually retracted into the partition under the action of the tapered portion until it is separated from the connecting hole; conversely, when the partition approaches the feeding pipe, the connecting pipe is gradually retracted into the partition under the action of the tapered inner wall of the oven until the connecting pipe is aligned with the connecting hole. The connecting pipe is inserted into the connecting hole under the action of the second elastic member, and the user does not need to control the extension and retraction of the connecting pipe separately. The structure is simple and the operation is convenient.

[0019] Optionally, a second baffle is slidably connected in the conical portion, a support rod fixedly connected to the oven is provided in the first heating chamber, one end of the support rod extends into the connecting tube and abuts against the second baffle, a third elastic member is connected between the second baffle and the connecting tube, and when the third elastic member is in a natural state, the second baffle closes the connecting tube.

[0020] By adopting the above technical solution, when adding materials, the second baffle closes the connecting tube under the action of the third elastic member, and the materials are not easy to accidentally enter the second heating chamber. When the connecting tube enters the connecting hole, the abutment of the abutment rod causes the second baffle to move, and the second baffle no longer closes the connecting tube, thereby realizing the connection between the first heating chamber and the second heating chamber. The structure is simple and the control is convenient.

[0021] Optionally, a fourth elastic member is connected between the partition and the oven. When the fourth elastic member is in a natural state, the partition is located outside the feeding pipe, a guide wheel is provided near the hinge of the sealing cover, and the feeding pipe is movably connected to a second connecting rope. One end of the second connecting rope is located in the feeding pipe and fixedly connected to the partition, and the other end is located outside the feeding pipe and bypasses the guide wheel and is fixedly connected to the outer side of the corresponding sealing cover.

[0022] By adopting the above technical solution, when the sealing cover is opened, the partition automatically enters an open state under the action of the fourth elastic member; when the sealing cover is closed, the guide wheel flips with the sealing cover, driving the second connecting rope to pull the partition into the feeding pipe, so that the partition enters a closed state. The structure is simple and the operation is convenient.

[0023] Optionally, the feeding tube is fixedly provided with a steering rod, which is arranged along the radial direction of the feeding tube, and the second connecting rope passes around the steering rod and is fixedly connected to the center position of the partition.

[0024] By adopting the above technical solution, under the action of the steering rod, the second connecting rope applies a pulling force to the partition along the central axis of the feeding tube, the force at different positions of the partition is more uniform, and the sliding of the partition along the guide rail is more stable.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When adding materials, the user opens the sealing cover and controls the movement of the partition, switches the partition to the open state, and then adds materials into the oven. After the materials are added, the user switches the partition to the closed state and closes the sealing cover, and then uses the hot fluid to enter the first heating chamber for heating and drying. The hot fluid can enter the second heating chamber from the connecting pipe. Even if the materials are gathered at a position close to the sealing cover, the hot fluid in the second heating chamber can still have a better drying effect on the materials, and the drying efficiency of the materials is high;

[0027] 2. The partition is rotatably connected to the feeding pipe by a connecting pipe. When the partition is at the radial section of the feeding pipe, the partition is in a closed state, and the material is not easy to fall back into the feeding pipe; when the partition is rotated to be away from the radial section of the feeding pipe, the partition is in an open state. The structure is simple and the two states of the partition can be switched more conveniently;

[0028] 3. When the partition slides along the guide rail to the outside of the feeding pipe, it enters the open state, and a gap appears between the partition and the inner wall of the oven, and the material can enter the oven through the gap; on the contrary, when the partition is located in the feeding pipe, it is within the diameter section of the feeding pipe and enters the closed state. The connecting pipe is inserted into the connecting hole to facilitate the hot fluid to enter the second heating chamber; the structure is simple and the two states of the partition can be switched more conveniently.

DETAILED DESCRIPTION

[0036] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0037] The embodiment of the present application discloses a material drying device.

[0038] Embodiment 1:

[0039] Reference Figure 1 A material drying device includes a support frame 1 and an oven 2. The oven 2 is rotatably connected to the upper end of the support frame 1. The support frame 1 is equipped with a driving component for controlling the rotation of the oven 2 and a heating component for providing a hot fluid to heat the oven 2. The driving component and the heating component are common settings of a common double-cone dryer, and this application will not elaborate on them.

[0040] Reference Figure 1 The middle position of the length direction of the oven 2 is cylindrical and rotatably connected to the support frame 1; the two ends are conical with gradually decreasing diameters, and are both connected with feeding pipes 3, one for feeding and the other for discharging. The feeding pipes 3 are all round tubes, and the ends of the two feeding pipes 3 away from the oven 2 are hinged with sealing covers 6. When adding materials, the user manually flips the sealing cover 6 of the corresponding feeding pipe 3 along the hinge to open it.

[0041] Reference Figure 2 and Figure 3 A partition 4 is installed in the feeding pipe 3. The partition 4 is circular and matches the inner diameter of the feeding pipe 3. Two connecting pipes 5 are fixedly connected to the partition 4. The two connecting pipes 5 are arranged along the radial direction of the partition 4 and are located on the opposite side of the partition 4. The ends of the two connecting pipes 5 away from the partition 4 are rotatably connected to the oven 2. The partition 4 has an open state for connecting the two ends of the feeding pipe 3. When the user opens the sealing cover 6, the partition 4 enters the open state.

[0042] Reference Figure 2 and Figure 3A first connecting rope 42 is connected between the sealing cover 6 and the corresponding partition 4, one end of the first connecting rope 42 is fixedly connected to one side of the partition 4, and the other end is fixedly connected to the center position of the sealing cover 6. The connection between the first connecting rope 42 and the partition 4 is at the same distance from the two connecting pipes 5. When the user flips and opens the sealing cover 6 along the hinge, the sealing cover 6 pulls the partition 4 to flip around the connecting pipe 5 through the first connecting rope 42. After the sealing cover 6 flips 90°, the partition 4 also flips 90°. At this time, the partition 4 is in the axial section of the feeding pipe 3, and the partition 4 enters the open state, and no longer closes the feeding pipe 3. At this time, the material can smoothly enter the oven 2 from the feeding pipe 3.

[0043] Reference Figure 2 and Figure 3 The partition 4 also has a closed state for closing the feeding pipe 3. When the sealing cover 6 is buckled, the partition 4 will enter the closed state. The two connecting pipes 5 are both sleeved with a torsion spring 51. One end of the torsion spring 51 is fixedly connected to the partition 4, and the other end is fixedly connected to the oven 2. When the sealing cover 6 is buckled, the torsion spring 51 is in a natural state. At this time, the partition 4 is at the radial section corresponding to the feeding pipe 3 under the action of the torsion spring 51, and the edge is in contact with the inner wall of the feeding pipe 3, so as to achieve the closure of the feeding pipe 3; when the feeding pipe 3 rotates to a lower position, the material falls on the partition 4 and is not easy to fall into the feeding pipe 3.

[0044] Reference Figure 2 A first heating chamber 21 is provided on the side wall of the oven 2. The heating component supplies hot air or other hot fluid into the first heating chamber 21, and utilizes heat conduction of the inner wall of the oven 2 to gradually heat up the interior of the oven 2.

[0045] Reference Figure 2 A second heating chamber 41 is opened in the partition 4, one end of the connecting pipe 5 is located in the partition 4 and communicated with the second heating chamber 41, and the other end penetrates the inner wall of the oven 2 and communicates with the first heating chamber 21. The hot fluid in the first heating chamber 21 enters the second heating chamber 41 through the connecting pipe 5, and the hot fluid in the second heating chamber 41 utilizes the heat conduction of the partition 4 to heat the material on the partition 4. The material can always be heated during the turning process, thereby achieving higher drying efficiency.

[0046] Reference Figure 2 and Figure 3 Under the action of the first connecting rope 42, when the user opens the sealing cover 6, the partition 4 enters the open state; when the user closes the sealing cover 6, the tension of the first connecting rope 42 on the partition 4 disappears, and the partition 4 enters the closed state under the action of the torsion spring 51. The opening and closing of the partition 4 does not require the user to control it separately. Compared with the common double-cone dryer, the user does not need to perform additional operations, and the drying efficiency is improved at the same time.

[0047] The implementation principle of Example 1 of the present application is as follows: when adding materials, the user opens the sealing cover 6, and the sealing cover 6 pulls the partition 4 around the connecting pipe 5 through the first connecting rope 42, so that the partition 4 enters the open state, and the material can smoothly enter the oven 2 from the feeding pipe 3. When the user closes the sealing cover 6, the pulling force of the first connecting rope 42 on the partition 4 disappears, and the partition 4 enters the closed state; when the feeding pipe 3 rotates to a lower position, the material falls on the partition 4. The hot fluid in the first heating chamber 21 enters the second heating chamber 41 through the connecting pipe 5, and the hot fluid in the second heating chamber 41 uses the heat conduction of the partition 4 to heat the material on the partition 4. The material can always be heated during the rotation process, thereby achieving higher drying efficiency.

[0048] Embodiment 2:

[0049] Reference Figure 4 and Figure 5 The main difference between this embodiment and the embodiment 1 is that the moving mode of the partition 4 is different. Guide rails 7 are installed at both ends of the length direction of the oven 2. The guide rails 7 correspond to the feeding tubes 3 one by one, and include three guide rods 71 ​​fixedly connected to the corresponding feeding tubes 3. The three guide rods 71 ​​are arranged at equal intervals along the circumference of the feeding tube 3, and the guide rods 71 ​​are all arranged along the axial direction of the feeding tube 3. The partition 4 is coaxially arranged with the feeding tube 3 and is slidably connected to the three guide rods 71 ​​of the corresponding guide rails 7, and can slide along the axial direction of the feeding tube 3.

[0050] Reference Figure 4 A fourth elastic member 711 is sleeved on the outside of each guide rod 71. The fourth elastic member 711 is a telescopic spring. One end of the fourth elastic member 711 is fixedly connected to the partition 4, and the other end is fixedly connected to the guide rod 71. When the sealing cover 6 is opened, the fourth elastic member 711 is in a natural state. The partition 4 is located at the end of the guide rail 7 away from the corresponding material feeding pipe 3, and is located outside the corresponding material feeding pipe 3. Since the inner diameter of the oven 2 gradually increases in the direction approaching the center, a gap is left between the edge of the partition 4 and the inner wall of the oven 2 at this time. The partition 4 is in an open state, and the user can open the sealing cover 6 to add materials into the oven 2.

[0051] Reference Figure 5 After the feeding is completed, the user closes the sealing cover 6 and the partition 4 enters a closed state. The outer side of the sealing cover 6 (i.e., the side of the sealing cover 6 away from the feeding tube 3) is fixedly connected with the second connecting rope 43, and the sealing cover 6 is fixedly connected with the guide wheel 61 near the hinged part with the feeding tube 3. The hinged part is located between the guide wheel 61 and the sealing cover 6. A through hole is opened on the wall of the feeding tube 3. The second connecting rope 43 bypasses the guide wheel 61 and penetrates into the feeding tube 3 through the through hole. As the sealing cover 6 is closed, the guide wheel 61 moves away from the feeding tube 3, thereby pulling the second connecting rope 43 out of the feeding tube 3.

[0052] Reference Figure 5and Figure 6 A turning rod 31 arranged along its radial direction is fixedly installed in the feeding tube 3, and the end of the second connecting rope 43 away from the sealing cover 6 passes around the turning rod 31 and is fixedly connected to the center position of the partition 4. The partition 4 is pulled toward the feeding tube 3 by the second connecting rope 43, and then moves into the feeding tube 3; after the partition 4 enters the feeding tube 3, it enters a closed state. At this time, the connecting pipe 5 connects the first heating chamber 21 with the second heating chamber 41, so that the hot fluid can enter the second heating chamber 41 to fully heat the material.

[0053] Reference Figure 6 , the two connecting pipes 5 are slidably connected to the partition 4, one end of the connecting pipe 5 extends into the second heating chamber 41 and is sleeved with a second elastic member 55, which is also a telescopic spring. In the natural state of the second elastic member 55, the other end of the connecting pipe 5 extends outside the partition 4. As the partition 4 approaches the connecting pipe 5, the connecting pipe 5 gradually abuts against the inner wall of the oven 2. Since the two ends of the oven 2 are tapered, the distance between the edge of the partition 4 and the inner wall of the oven 2 gradually decreases, and the connecting pipe 5 is pushed by the inner wall of the oven 2 to slide into the second heating chamber 41.

[0054] Reference Figure 6 After the partition 4 enters the feeding tube 3, the connecting tube 5 completely enters the partition 4. The feeding tube 3 is provided with two connecting holes 22 communicating with the first heating chamber 21, and the connecting holes 22 correspond to the connecting tubes 5 one by one. When the sealing cover 6 is fully buckled, the connecting tubes 5 are aligned with the corresponding connecting holes 22. Under the elastic restoring force of the second elastic member 55, the connecting tubes 5 move outward from the partition 4. The end of the connecting tube 5 away from the second elastic member 55 is provided with a tapered portion 52 with a gradually decreasing diameter, and the tapered portion 52 moves toward the corresponding connecting hole 22.

[0055] Reference Figure 6 A first baffle 23 is slidably connected to the connecting hole 22. A slope is provided on the side of the first baffle 23 close to the feeding tube 3. The tapered portion 52 abuts against the slope, giving the first baffle 23 a sliding force, so that the first baffle 23 slides to one side, and the tapered portion 52 smoothly penetrates into the connecting hole 22.

[0056] Reference Figure 6 Two push rods 25 are installed in the first heating chamber 21. The push rods 25 are fixed on the oven 2 and correspond to the connection holes 22 one by one. The push rods 25 are directly opposite to the center of the corresponding connection holes 22. After the connection pipe 5 is inserted into the connection hole 22, the push rods 25 are inserted into the tapered portion 52 of the corresponding connection pipe 5. A mounting frame 54 and a second baffle 53 are installed in the tapered portion 52. The mounting frame 54 and the tapered portion 52 are integrally formed. The second baffle 53 is slidably connected to the mounting frame 54 along the axial direction of the connection pipe 5. As the connection pipe 5 is inserted into the connection hole 22, the push rods 25 push the second baffle 53 toward the direction close to the partition 4.

[0057] Reference Figure 6 Due to the change in the inner diameter of the tapered portion 52, a gap appears between the second baffle 53 and the inside of the connecting pipe 5 during movement. The hot fluid in the first heating chamber 21 can pass through the second baffle 53 through the gap and enter the second heating chamber 41, thereby improving the heating efficiency.

[0058] Reference Figure 5 and Figure 6 After the heating is completed, the user opens the sealing cover 6 to prepare for discharging. During the process of opening the sealing cover 6, the guide wheel 61 moves toward the direction close to the feeding tube 3, and the second connecting rope 43 loses its pulling effect on the partition 4. At this time, the partition 4 slides away from the feeding tube 3 under the action of the fourth elastic member 711; the outer wall of the tapered portion 52 contacts the hole wall of the connecting hole 22. Since the outer wall of the tapered portion 52 is inclined, during the sliding process of the partition 4, the hole wall of the connecting hole 22 gives the connecting tube 5 a thrust to retract the partition 4 through the tapered portion 52, thereby causing the connecting tube 5 to detach from the connecting hole 22, thereby ensuring that the partition 4 moves smoothly to the outside of the feeding tube 3.

[0059] Reference Figure 6 , the partition 4 moves to the outside of the material delivery pipe 3 and then returns to the open state, at which time the material can be discharged from the material delivery pipe 3. A third elastic member 56 is connected between the second baffle 53 and the mounting frame 54, and at this time the third elastic member 56 pushes the second baffle 53 away from the partition 4, so that the second baffle 53 abuts against the inner wall of the tapered portion 52, thereby closing the connecting pipe 5, and the movement of the material is not easy to accidentally enter the connecting pipe 5.

[0060] Reference Figure 6 A first elastic member 24 is connected between the first baffle 23 and the oven 2. After the conical portion 52 is separated from the connecting hole 22, the elastic restoring force of the first elastic member 24 causes the first baffle 23 to slide back to the initial position to close the connecting hole 22, so that the material is not easy to accidentally enter the first heating chamber 21 through the connecting hole 22.

[0061] The implementation principle of Example 2 of the present application is as follows: when adding materials, the user opens the sealing cover 6, and the second connecting rope 43 loses its pulling effect on the partition 4. At this time, the partition 4 slides away from the feeding pipe 3 under the action of the fourth elastic member 711, so that the partition 4 enters the open state, and the materials can smoothly enter the oven 2 from the feeding pipe 3. When the user closes the sealing cover 6, the partition 4 is pulled into the feeding pipe 3 by the second connecting rope 43, and then moves into the connecting pipe 5; after the partition 4 enters the feeding pipe 3, it enters the closed state; under the elastic restoring force of the second elastic member 55, the connecting pipe 5 penetrates into the connecting hole 22, and the hot fluid in the first heating chamber 21 enters the second heating chamber 41 through the connecting pipe 5, thereby achieving higher drying efficiency.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
