[0026] Example 1

[0027] See also Figure 1The utility model embodiment provides a vertical white mud drying furnace. When the vertical drying furnace is set up, it is generally necessary to have a supporting part, such as a wall. By providing the supporting part, the vertical drying furnace is more stable during operation. It includes a furnace body 10 and a drying part arranged inside the furnace body 10; the furnace body 10 is arranged in a cylindrical shape and has a accommodating cavity inside; the drying part includes a rotating shaft 31 and a drying layer plate 32; the drying layer plate 32 is attached to the rotating shaft 31. The surface of the drying layer plate 32 is a material receiving surface. The white mud is dried on the surface of the drying layer plate 32. And the material also rises with the rotation of the drying layer plate 32. The rotation of the rising drying layer plate 32 is driven by the rotation of the rising rotating shaft 31 to rotate the rising drying layer plate 32. Please refer to Figure 3 , the drying layer plate 32 is extended from the bottom of the rotating shaft 31 to the top of the rotating shaft 31; the drying layer plate 32 is set in a spiral shape. The white mud on the material receiving surface can reach an upward trend as the drying layer plate 32 rotates through the setting of the spiral drying layer plate 32, and the length of the rising time is inversely proportional to the preset rotation speed of the rotating shaft 31. When it is necessary to set a longer drying time for the white mud, the rotation speed of the rotating shaft 31 is rotated slowly, so that the white mud is placed on the drying layer plate 32 for a longer time, and the drying time experienced by the white mud is also longer, so as to achieve a better drying effect. When it is necessary to dry the white mud for a shorter time, the rotation speed of the rotating shaft 31 is increased to a faster speed, and the white mud is on the drying layer plate 32 for a shorter time, so that it can complete the discharge faster, so that a faster drying time can be obtained. The driving motor 41 is mounted on the furnace body 10 via a motor mounting bracket 44 , and the driving motor 41 is fixedly arranged via the motor mounting bracket 44 .

[0028] A drying chamber 11 is provided between the top and the bottom of the furnace body 10. The storage space inside the furnace body 10 is not only for storing the drying components, but also for the drying chamber 11. The white mud is heated and dried in the drying chamber 11. The drying layer plate 32 generates a large amount of heat and steam when in contact with the white mud. The steam circulates in the drying chamber 11, so that the inside thereof is kept at a relatively high temperature. Furthermore, since there is a large amount of water in the steam, it may adhere to the top of the furnace body 10 and drip onto the white mud, affecting the drying effect. An air outlet pipe is provided on the top of the furnace body 10. The water vapor is discharged through the air outlet pipe, so that the inside of the drying chamber 11 is kept in a relatively dry and high-temperature environment.

[0029] See also Figure 2 and Figure 4, heating elements are arranged at intervals inside the drying layer 32. The heating element includes a heating tube 35. Furthermore, the heating tube 35 can be a heating tube 35 arranged in a serpentine shape inside the drying layer 32. It can also be a plurality of heating tubes 35. Preferably, the utility model adopts the setting of a plurality of heating tubes 35, and the heating and drying time can also be changed by controlling different numbers of heating tubes 35. The heating tube 35 is arranged between the top plate 321 and the bottom plate 322 of the drying layer 32. The heating tube 35 is an electric heating tube 35, which generates heat transfer between the top plate 321 after heating, so that the temperature of the top plate 321 and the bottom plate 322 are increased, and then it is contacted with the white mud to dry the white mud. The white mud may have a lot of water. When the white mud has a lot of water, it will flow downward with the drying layer 32, and only a small layer of white mud will be attached to the drying layer 32. After falling several times, it enters the drying layer plate 32, and circulates back and forth to dry the white mud. The white mud with less water will directly adhere to the drying layer plate 32, dry and agglomerate, and then be transported out.

[0030] See also Figure 4 Furthermore, in order to ensure that the temperature of the furnace body 10 does not lose, a heat preservation cavity 33 is provided on the side wall of the furnace body 10, and a heat preservation material 34 is provided in the heat preservation cavity 33. First, the inner wall of the furnace body 10 is set as a furnace wall 49, which is made of a heat preservation material 34 such as ceramic. A cavity is provided between the furnace walls 49, and a heat preservation material 34 is provided in the cavity, which can prevent temperature loss and prevent potential dangers due to heat. The furnace wall 49 can prevent the internal heat from being transferred out and prevent fire from occurring after the temperature rises.

[0031] See also Figure 2 and Figure 4The side wall of the furnace body 10 is provided with a heat preservation chamber 33, and the heat preservation chamber 33 is provided with a heat preservation material 34; the upper surface of the drying layer plate 32 is a material receiving surface. A driving component is also provided on the top of the furnace body 10. The driving component includes a driving motor 41, a first driven wheel 42, a first bearing seat 43 and a second bearing seat 45. The first bearing seat 43 and the second bearing seat 45 are respectively arranged at both ends of the furnace body 10; the two ends of the rotating shaft 31 are respectively connected to the first bearing seat 43 and the second bearing seat 45. The driving wheel 46 arranged on the output shaft of the driving motor 41 is connected to the first driven wheel 42 through a belt 48. The rotation of the rotating shaft 31 is based on the first bearing seat 43 and the second bearing seat 45. A driving wheel 46 is arranged on the output shaft of the driving motor 41, and the driving wheel 46 is connected to the first driven wheel 42 through a belt 48. By starting the driving motor 41, the first driven wheel 42 is driven to rotate through the driving wheel 46, so that its rotating shaft 31 rotates based on the first bearing seat 43 and the second bearing seat 45, so that the spirally arranged drying layer plate 32 rotates, and the white mud on the material receiving surface moves upward.

[0032] Example 2

[0033] See also Figure 1 and Figure 2 The embodiment of the utility model provides a vertical white mud drying furnace, wherein a feed port 13 is provided at the bottom of the furnace; a discharge port 12 is provided at the top of the furnace body 10. The feed port 13 is provided with a storage bin 14; and the discharge port 12 is provided with an auxiliary discharge channel 15. When the white mud is transported to the drying furnace, it is first stored in the storage bin 14. The storage bin 14 assists the feeding of the white mud in the storage bin 14 through a feed pipe 16. The storage bin 14 is connected with the feed port 13 through the feed pipe 16, so that the white mud can directly enter the drying layer plate 32. The storage bin 14 is connected with the feed port 13 of the furnace body 10 through the feed pipe 16; the feed pipe 16 and the feed port 13 are connected by a flange 161.

[0034] For further information, see Figure 2, an auxiliary feeding mechanism is provided inside the feeding pipe 16; the auxiliary feeding mechanism includes an auxiliary feeding grid plate head 21; the auxiliary feeding grid plate head 21 is arranged on a rotating roller 22; at least three auxiliary feeding plates 211 arranged at intervals are arranged on the auxiliary feeding grid plate head 21. When there is a lot of white mud accumulation, the feeding port 13 will be blocked, resulting in the inability to perform normal feeding work. At this time, the feeding port 13 needs to be manually unblocked, which is more troublesome. Therefore, an auxiliary feeding mechanism is set. The auxiliary feeding mechanism is provided with an auxiliary feeding grid plate head 21, and at least three auxiliary feeding plates 211 are arranged on the auxiliary feeding grid plate head 21 at uniform angle intervals. The auxiliary feeding grid plate head 21 rotates based on the rotating roller 22. Thereby, the material at the feeding port 13 is moved by the auxiliary feeding plate 211. The first bearing seat 43 is connected to a second driven wheel 212 outside the furnace body 10; a third driven wheel 213 is provided at the bottom of the auxiliary feed grid head 21; and the roller 22 is connected to the third driven wheel 213. The auxiliary feed grid head 21 is fixedly sleeved on the roller 22, and the roller 22 is rotated by the transmission between the second driven wheel 212 and the third driven wheel 213, so as to move the material at the feed port 13.

[0035] For further information, see Figure 2 The second driven wheel 212 and the third driven wheel 213 are driven by a belt; the rotation speed of the second driven wheel 212 and the third driven wheel 213 is consistent with the rotation speed of the rotating shaft 31. The rotation speed of the roller 22 is consistent with the rotating shaft 31, so that the feeding speed is consistent with the expected drying time, and the material can be dried and fed continuously.

[0036] For further information, see Figure 3 , an auxiliary discharge plate 17 is provided on the top of the rotating shaft 31; the auxiliary discharge plate 17 sets the top of the drying layer plate 32 in a closed manner; the auxiliary discharge plate 17 is sleeved on the rotating shaft 31 and fixed on the inner wall of the top of the furnace body 10. After being dried, the white mud will generally clump and solidify on the drying layer plate 32, making it difficult to discharge. Therefore, a fixed auxiliary discharge plate 17 is provided on the top of the furnace body 10. When the dried white mud is transported to the discharge port 12 as the drying layer plate 32 rotates, the solidified white mud is not easy to discharge. Through the auxiliary discharge plate 17, the white mud contacts the auxiliary discharge plate 17, so that the white mud can no longer move upward, and is blocked by the auxiliary discharge plate 17. A relative force is generated between the auxiliary discharge plate 17 and the white mud, causing the white mud to fall off and be discharged. The white mud is directly discharged to a preset position through the auxiliary discharge channel 15, such as directly discharged to a transport vehicle, discharged to a storage bin, etc. It is more convenient and quick for discharging, and there is no need to transport the white mud to the expected location again.

[0037] Preferably, a gap is provided between the drying layer plate 32 and the inner wall of the furnace body 10; the gap is provided between the furnace body 10 and the inner wall to allow for overall circulation, thereby preventing excessive pressure on the inner wall.

[0038] Example 3

[0039] See also Figure 1 and Figure 2 The embodiment of the utility model provides a vertical white mud drying furnace, which has the following beneficial effects: by arranging a spiral drying layer plate 32 inside the furnace body 10, the material is heated on the drying layer plate 32, and hot air is generated to circulate in the drying chamber 11, so that the white mud can achieve a drying effect. The white mud is dried for a conveying length, and the drying time of the white mud is adjusted by adjusting the rotation speed of the rotating shaft 31 to achieve a drying effect. And through the spiral drying layer plate 32, the white mud is dried while rising, and after reaching the expected drying time, it is transported to the discharge place, and the dried white mud is transported out through the spiral drying layer plate 32. The vertical white mud drying furnace can control the drying time by controlling the rotation speed of the rotating shaft 31 to achieve the expected drying effect. It can also dry while, and automatically complete the discharge work after the drying is completed, which is convenient to operate and reduces manual operation. By adjusting the rotation speed of the rotating shaft 31, the residence time of the white mud on the drying layer plate 32 can be controlled, thereby realizing flexible control of the drying time and improving the drying efficiency. The furnace body 10 is designed with a heat preservation chamber 33 and a heating tube 35, which can effectively control the temperature during the drying process, improve the drying effect and ensure safety. The design of the feed port 13, the auxiliary feed mechanism and the setting of the auxiliary discharge plate 17 make the feeding and discharging of the white mud more convenient and quick, and improve the operating efficiency. In general, the optimization of these designs and structures helps to improve the working efficiency, stability and operating convenience of the white mud drying furnace, thereby achieving better drying effect and working effect.
