Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transmission bearing in high temperature and high humidity environment and the technical field of red mud material hot reaction device, and particularly relates to a control bearing for high temperature and high humidity environment and a red mud hot reaction pressure device. BACKGROUND

[0002] Red mud material is waste slag discharged after extraction of alumina, and contains iron, titanium and other rare and precious metals. However, extraction of other elements in the red mud material in the prior art is relatively complex, and the red mud has pollution, and direct discharge into the environment will pollute the surrounding environment.

[0003] Red mud material hot reaction can make the red mud material generate chemical reaction to generate recyclable metal compounds. In one link, the red mud material is heated to high temperature and then introduced into low-temperature liquid medicine, so that the fission reaction occurs, and the required metal compounds can be effectively obtained. However, a large amount of high-temperature water vapor is generated in this reaction, so as to avoid affecting the environment, the process is generally completed in a sealed warehouse.

[0004] On the other hand, when the red mud material is added to the liquid medicine, part of the red mud material will float on the water surface, so that the high-temperature red mud material cannot be in contact with the liquid medicine in time, and the effect of the red mud material hot reaction is reduced. The red mud material floating above the liquid medicine can be pressed into the liquid medicine by the rotating pressure device to fully contact with the liquid medicine.

[0005] In order to maintain the pressure effect of the red mud material at different liquid medicine heights, the pressure device vertically presses the red mud material into the liquid medicine, and the angle of the pressure device can be adjusted to adapt to different liquid medicine heights. However, when the pressure angle of the pressure device is adjusted, an adjusting groove is separately formed in the rotating shaft of the pressure device, and an adjusting structure is separately arranged in the adjusting groove. High-temperature and high-humidity air directly enters the adjusting groove, and the adjusting groove and the adjusting structure inside the adjusting groove are easily corroded after long-term use, and the structure is easily damaged.

[0006] In addition, the bearing is easily corroded inside after long-term use in high-temperature and high-humidity environment, and the friction resistance is increased during rotation.

[0007] Therefore, a solution capable of maintaining the integrity of the rotating shaft of the pressure device and adjusting the pressure angle of the pressure device is needed. SUMMARY

[0057] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0058] Embodiment 1:

[0059] Reference Figures 1-8 A control bearing for high-temperature and high-humidity environment, characterized in that it comprises:

[0060] Outer ring 11, inner ring 12, rolling element 13, and sealing sleeve;

[0061] The rolling element 13 is in rolling contact with the outer side of the inner ring 12 and the inner side of the outer ring 11. In the present application, the rolling element 13 is spherical or cylindrical, and rolling contact with the inner ring 12 and the outer ring 11 to reduce the friction when the outer ring 11 and the inner ring 12 rotate.

[0062] The inner ring 12 is provided with a sliding key 121 extending towards the axis of the inner ring 12;

[0063] The sealing sleeve comprises an outer sleeve ring 2 and an inner sleeve ring 3;

[0064] The outer sleeve ring 2 is sealingly connected to the end of the outer ring 11;

[0065] The inner sleeve ring 3 has a fixed hole 31 with a diameter smaller than the small diameter of the inner ring 12, and a sealing key 311 is provided on the inner side of the fixed hole 31;

[0066] The outer sleeve ring 2 has an outer sealing ring piece 21 extending towards the center line direction, and the inner sleeve ring 3 has an inner sealing ring piece 32 extending away from the fixed hole 31 direction;

[0067] The outer sealing ring piece 21 is at least two groups, and at least two groups of outer sealing ring pieces 21 are distributed along the axis direction of the outer sleeve ring 2, and the interval distance between adjacent outer sealing ring pieces 21 is the thickness of the inner sealing ring piece 32;

[0068] The inner sealing ring piece 32 is at least two groups, and at least two groups of inner sealing ring pieces 32 are distributed along the axis direction of the inner sleeve ring 3, and the interval distance between adjacent inner sealing ring pieces 32 is the thickness of the inner sealing ring piece 32;

[0069] Among them, at least two groups of outer sealing ring pieces 21 and at least two groups of inner sealing ring pieces 32 are matched with each other.

[0070] It should be noted that in the present application, the finger insertion refers to the insertion of the outer sealing ring piece 21 and the inner sealing ring piece 32 into the opposite interval gap.

[0071] The bearing used in high temperature and high humidity environment can accelerate the corrosion between the connection of the bearing and the rotating shaft 4 and each rotating part of the bearing. The consequence of bearing corrosion increases the rotating friction of the bearing. If it cannot be found in time, even if the bearing is damaged directly due to the increase of friction.

[0072] And the arrangement of the transmission device through the hole in the rotating shaft 4 (as shown in Figure 14 The inside of the rotating shaft will collect liquid condensed by high temperature and high humidity. After a certain period of use, the transmission device arranged in the rotating shaft 4 will appear corrosion phenomenon.

[0073] The embodiment provides a control bearing for high temperature and high humidity environment. The bearing and the rotating shaft 4 connected with the bearing are directly exposed to the high temperature and high humidity environment to prevent corrosion. At the same time, the relative movement between the rotating shaft 4 and the bearing can be used to control the pressing device, and the water collection space of the rotating shaft 4 structure is reduced.

[0074] Specifically, the inner ring 12 and the outer ring 11 of the control bearing are connected through the retainer, the retainer keeps the steel ball between the inner ring 12 and the outer ring 11, so that the inner ring 12 and the outer ring 11 can relatively stably rotate, and the friction between the inner ring 12 and the outer ring 11 is reduced.

[0075] The inner ring 12 is provided with a sliding key 121, which can be connected with the shaft 4 and the sliding key 121 through the key groove 41 on the surface, so that the shaft 4 has the freedom to move towards the axis of the inner ring 12 when rotating with the inner ring 12. The adjustment of the pressing device can be realized by converting the movement of the shaft 4 into the action of adjusting the angle of the pressing device, and no other transmission structure is needed.

[0076] The sealing sleeve is used to seal the bearing and the connection between the shaft 4 and the bearing, preventing high-temperature water vapor from entering. The inner sleeve ring 3 is directly sleeved on the shaft 4 through the fixing hole 31, and the sealing key on the fixing hole 31 can seal the surface of the shaft 4 after the key groove 41 is opened. When the shaft 4 moves along the axis, the inner sleeve ring 3 also moves with the shaft 4.

[0077] The outer sleeve ring 2 is sealingly connected to the end of the outer ring 11, and the outer sleeve ring 2 and the inner sleeve ring 3 are inserted and matched through the outer sealing ring piece 21 and the inner sealing ring piece 32. When the inner sleeve ring 3 rotates relative to the outer sleeve ring 2 driven by the shaft 4, the inner sealing ring piece 32 also rotates relative to the outer sealing ring piece 21. The distance between the inner sealing ring piece 32 and the outer sealing ring piece 21 is set to always maintain a sealing contact between the side of the inner sealing ring piece 32 and the side of the outer sealing ring piece 21. Even when the inner sealing ring piece 32 and the outer sealing ring piece 21 rotate relative to each other, high-temperature water vapor can still be prevented from entering, so as to prevent corrosion of the contact part between the inner sleeve ring 3 and the outer sleeve ring 2 and the shaft 4.

[0078] Embodiment 2:

[0079] Referring to Figure 2 , Figure 3 Further, the outer sleeve ring 2 further comprises a flexible sealing sleeve 22, and the flexible sealing sleeve 22 has a first open end 221 and a second open end 222.

[0080] The first open end 221 is sealingly connected to the end of the outer sleeve ring 2, and the second open end 222 is sealingly connected to the end of the outer ring 11.

[0081] The outer sleeve ring 2 and the outer ring 11 are flexibly and sealingly connected through the sealing sleeve.

[0082] The flexible sealing sleeve 22 is sleeved between the outer sleeve ring 2 and the outer ring 11. When the shaft 4 moves relative to the inner ring 12 along the axis, the inner sleeve ring 3 fixedly connected with the shaft 4 is driven by the shaft 4 to move synchronously, and the outer sleeve ring 2 inserted and matched with the inner sleeve ring 3 through the inner sealing ring piece 32 and the outer sealing ring piece 21 also moves with the inner sleeve ring 3, while the inner ring 12 and the outer ring 11 remain stationary.

[0083] The flexible sealing sleeve 22 is arranged between the outer sleeve ring 2 and the inner sleeve ring 3, and can be deformed to adapt to the change of the position of the outer sleeve ring 2 when the outer sleeve ring 2 moves relative to the outer ring 11, while keeping the seal between the outer sleeve ring 2 and the inner sleeve ring 3.

[0084] In some embodiments, the flexible sealing sleeve 22 can be made of flexible rubber with good corrosion resistance.

[0085] Embodiment 3

[0086] With reference to Figure 3 Further, the outer ring 11 further comprises a limiting slide bar 111, one end of the limiting slide bar 111 is fixedly connected to the end of the outer ring 11, and the other end of the limiting slide bar 111 extends away from the end of the outer ring 11.

[0087] The length direction of the limiting slide bar 111 is parallel to the axis direction of the outer ring 11.

[0088] The outer sleeve ring 2 further comprises a limiting hole 23, and the length direction of the limiting hole 23 coincides with the center line of the outer sleeve ring 2.

[0089] The limiting hole 23 and the limiting slide bar 111 are in sliding fit, and the limiting slide bar 111 limits the movement of the limiting hole 23 in the direction other than the length direction of the limiting slide bar 111.

[0090] The flexible sealing sleeve 22 does not have the ability to maintain shape, and will deform to adapt to the movement of the outer sleeve ring 2 when the outer sleeve ring 2 rotates or moves, especially when the inner sleeve ring 3 rotates. The outer sleeve ring 2 will twist the flexible sealing sleeve 22 to a certain extent before the inner sleeve ring 3 and the outer sleeve ring 2 can rotate relative to each other, and the long-term twisting of the flexible sealing sleeve 22 can easily cause fatigue of the material of the flexible protective sleeve, eventually leading to seal failure.

[0091] In this embodiment, the limiting slide bar 111 limits the movement of the limiting hole 23 and the outer sleeve ring 2 fixedly connected with the limiting hole 23 to be only in the axis direction of the outer ring 11, and cannot rotate relative to the outer ring 11 in the axis direction.

[0092] When the inner sleeve ring 3 rotates relative to the outer sleeve ring 2, the relative fixation of the outer sleeve ring 2 is maintained and does not rotate with the rotation of the inner sleeve ring 3. When the inner sleeve ring 3 moves towards one end of the inner ring 12, the limiting hole 23 on the outer sleeve ring 2 can move in the length direction of the limiting slide bar 111, so that the flexible sealing sleeve 22 deforms to adapt to the change of the position of the outer sleeve ring 2, and the seal is maintained.

[0093] Embodiment 4

[0094] With reference to Figure 2 , Figure 4Further, in the interlocking of the outer sealing ring piece 21 and the inner sealing ring piece 32, the end of the outer sealing ring piece 21 is away from the end of the outer ring 11;

[0095] The outer sleeve ring 2 away from the end of the outer ring 11 further comprises an air isolation ring piece 24, the air isolation ring piece 24 extends to the center line direction of the outer sleeve ring 2, and the outer sealing ring piece 21 is arranged between the air isolation ring piece 24 and the outer ring 11;

[0096] Wherein, the air isolation ring piece 24 and the inner sleeve ring 3 have an air suction channel 241 therebetween;

[0097] Wherein, the outer sleeve ring 2 between the outer sealing ring piece 21 and the air isolation ring piece 24 is further provided with an air inlet 25;

[0098] The inner sleeve ring 3 is sleeved with an air suction blade group 33, and the rotation axis 4 of the air suction blade group 33 coincides with the axis of the fixed hole 31;

[0099] The air suction blade group 33 is driven to rotate by the inner sleeve ring 3, so as to suck the air between the outer sealing ring piece 21 and the air isolation ring piece 24 to one side of the air suction blade group 33.

[0100] Only through the sealing mode of the contact between the inner sealing ring piece 32 and the outer sealing ring piece 21, there is still a problem that part of the water vapor enters the sealing area between the inner sleeve ring 3 and the outer sleeve ring 2 after passing through the gap between the inner sealing ring piece 32 and the outer sealing ring piece 21 after a long time of rotation, which is not conducive to the long-term use of the bearing.

[0101] In the embodiment, the air suction blade group 33 is used to suck the air at the opening of the outer sealing ring piece 21 farthest away from the outer ring 11, so as to avoid the water vapor staying at the inner diameter opening of the outer sealing ring piece 21, that is, to avoid the water vapor entering the sealing space between the inner sleeve ring 3 and the outer sleeve ring 2 from the contact surface between the outer sealing ring piece 21 and the inner sealing ring piece 32.

[0102] The special connection mode between the interlocking inner sealing ring piece 32 and the outer sealing ring piece 21 only has a sliding contact gap opening at the extension end of the inner sealing ring piece 32 and the outer sealing ring piece 21, and in the embodiment, the sealing ring piece 27 farthest away from the outer ring 11 is set as the outer sealing ring piece 21, so that the opening of the outer sealing ring piece 21 is arranged close to the inner sleeve ring 3, and the possible opening of the external water vapor into the sealing space is smaller. When the air suction blade group 33 rotates to suck the air at the outer sealing ring piece 21, the diameter of the side close to the inner sleeve ring 3 is smaller, so that the sucked air is more concentrated.

[0103] The air-insulating ring 24 isolates the suction blade assembly 33 and the outer sealing ring 21 on both sides of the air-insulating ring 24. There is only a suction channel 241 on the side near the inner ring 3. The air drawn in passes through the suction channel 241 before reaching the suction blade assembly 33. The suction channel 241 and the outer sealing ring 21 are both located on the side near the inner ring 3. When suctioning, the air near the entire opening of the outer sealing ring 21 is sucked away.

[0104] In this embodiment, the suction blade assembly 33 can be driven by being fixedly connected to the inner ring 3. When the inner ring 3 rotates, the suction blade assembly 33 also rotates synchronously with the inner ring 3.

[0105] Example 5:

[0106] Reference Figures 2-5 Furthermore, the windproof ring 24 is tapered in the length direction of the outer ring 2;

[0107] At the end near the inner ring 3, the distance between the air-insulating ring 24 and the outer sealing ring 21 is L1;

[0108] At the end near the outer outer ring 2, the distance between the air-insulating ring 24 and the outer sealing ring 21 is L2;

[0109] The air-insulating ring 24 is configured such that L1 is less than L2.

[0110] like Figure 5 As shown, the air-insulating ring 24 is inclined on one side in the cross-section along the length of the outer ring 2, and the inclined opening between the side closer to the outer ring 2 and the outer sealing ring is large, while the inclined opening between the side closer to the inner ring 3 and the outer sealing ring is small.

[0111] On the side where the suction blade assembly 33 is set, the opening is smaller at the end near the suction channel 241 and larger at the end near the suction blade assembly 33.

[0112] As the air is drawn in from the air inlet 25 into the suction channel 241 and then into the suction blade assembly 33, the airflow moves from the large opening section to the small opening section and back to the large opening section. During the entire flow process, the airflow speed at the small opening section is faster, which allows the airflow containing moisture to pass quickly through the outer sealing ring 21, reducing the residence time. At the same time, a negative pressure can be generated at the small opening section, which performs negative pressure adsorption at the opening of the outer sealing ring 21, further reducing the moisture between the outer sealing ring 21 and the inner sealing ring 32.

[0113] Example 6:

[0114] Reference Figure 5 , Figure 6Further, the air suction blade group 33 comprises an inner rotating ring 331, an outer rotating ring 332 and blades 334;

[0115] The blades 334 are provided in groups.

[0116] The outer rotating ring 332 is arranged outside the inner rotating ring 331.

[0117] The blades 334 are arranged between the inner rotating ring 331 and the outer rotating ring 332.

[0118] The length direction of the blades 334 passes through the center of the inner rotating ring 331.

[0119] The inner sleeve ring 3 is further provided with an inner ring gear 35, the rotation axis of the inner ring gear 35 coincides with the axis of the fixed hole 31, the inner ring gear 35 and the inner sleeve ring 3 are connected through a support rod 351.

[0120] The inner rotating ring 331 is rotationally connected with the inner sleeve ring 3, and the outer side of the outer rotating ring 332 is provided with an outer ring gear 333.

[0121] The outer ring gear 333 and the inner ring gear 35 are driven through meshing transmission of a transmission gear 36, and the central shaft of the meshing gear is fixedly arranged on the air isolation ring 24.

[0122] In some use scenarios, the rotation of the rotating shaft 4 is slow, and if the air suction blade group 33 maintains the same rotation speed as the rotating shaft 4 at this time, the air suction effect is limited in the process of rotation, and the water vapor at the opening of the outer sealing ring 21 cannot be quickly removed.

[0123] In this embodiment, the suction blade group 33 is fixed and rotatable on the inner sleeve ring 3 by the inner rotating ring 331, and an outer gear ring 333 is arranged outside the suction blade group 33. The outer gear ring 333 is fixed on the inner sleeve ring 3, and the diameter of the inner gear ring 35 is greater than that of the outer gear ring 333. When the inner sleeve ring 3 rotates, the outer gear ring 333 fixedly connected between the support rod 351 and the inner sleeve ring 3 rotates together with the inner sleeve ring 3. The transmission gear 36 is engaged with the outer gear ring 333 and the inner gear ring 35 respectively. When the outer gear ring 333 rotates, the inner gear ring 35 is driven to rotate synchronously. Since the outer gear ring 333 is arranged on the outer rotating ring 332 of the suction blade group 33, the suction blade group 33 also rotates together at this time. The diameter of the inner gear ring 35 is greater than that of the outer gear ring 333, the modulus between the indirectly engaged gears is the same, the number of teeth of the larger diameter inner gear ring 35 is greater than that of the outer gear ring 333, and the transmission ratio is greater than 1. At this time, when the inner gear ring 35, i.e., the inner sleeve ring 3, rotates one circle, the number of rotations of the outer gear ring 333, i.e., the suction blade group 33, is greater than one circle. The rotation of the suction blade group 33 is accelerated, so that when the rotating shaft 4 rotates slowly, the suction blade group 33 can maintain a high rotating speed to suck air on one side of the air separation ring 24.

[0124] Embodiment 7:

[0125] With reference to Figure 5 , further, the outer rotating ring 332 is provided with a rotating sealing ring 37 at one end close to the air separation ring 24, and one end of the rotating sealing ring 37 is sealingly fixed on the outer rotating ring 332.

[0126] The other end of the rotating sealing ring 37 away from the outer rotating ring 332 is in sliding contact with the air separation ring 24.

[0127] The rotating sealing ring 37 seals and blocks the opening of the suction blade group 33 and the air separation ring 24 away from the inner sleeve ring 3, avoiding air entering from between the air separation ring 24 and the outer rotating ring 332 away from the inner sleeve ring 3, so as to maintain the air suction strength at the air suction passage 241.

[0128] Embodiment 8:

[0129] With reference to Figure 3 , Figure 5 , further, the air separation ring 24 and the adjacent outer sealing ring 21 further comprise an air suction ring 26.

[0130] The air suction ring 26 comprises a first ring 261 and a second ring 262, and the first ring 261 and the second ring 262 are respectively fixedly connected to one side of the air inlet 25 close to the air separation ring 24 and the outer sealing ring.

[0131] The first ring piece 261 and the second ring piece 262 extend outwardly along the center line direction of the outer sleeve ring 2 and abut against each other.

[0132] When the rotating shaft 4 does not rotate, the air suction blade group 33 also does not rotate to generate suction force to suck away the water vapor near the opening of the outer sealing ring piece 21. If the air inlet 25 is always kept open, the high-temperature and high-humidity air can directly enter from the air inlet 25, which causes the water vapor to gather between the outer sleeve ring 2 and the inner sleeve ring 3.

[0133] In this embodiment, the first ring piece 261 and the second ring piece 262 of the air suction ring piece 26 are kept in the abutting state away from the end of the air inlet 25 when the air suction blade group 33 does not rotate. The mutual abutment between the first ring piece 261 and the second ring piece 262 can prevent the external water vapor from entering between the outer sleeve ring 2 and the inner sleeve ring 3 from the air inlet 25.

[0134] When the rotating shaft 4 rotates and drives the air suction blade group 33 to rotate, the suction force is generated between the outer sleeve ring 2 and the inner sleeve ring 3 to pull apart the mutually abutting first ring piece 261 and the second ring piece 262, expose the gap between the first ring piece 261 and the second ring piece 262, and let the external air enter between the outer sleeve ring 2 and the inner sleeve ring 3, so that the high-speed flowing air is generated at the air inlet passage to prevent the water vapor from entering the opening of the outer sealing ring piece 21.

[0135] Embodiment 9:

[0136] With reference to Figure 2 , Figure 5 , Figure 8 Further, the outer sleeve ring 2 further comprises a sealing ring piece 27 and a one-way exhaust sleeve ring 28.

[0139] One end of the one-way exhaust sleeve ring 28 is fixedly connected with the small ring end of the sealing ring piece 27, and the other end of the one-way exhaust sleeve ring 28 is sleeved on the inner sleeve ring 3 and extends away from the outer ring 11.

[0140] The sealing ring piece 27 and the one-way exhaust sleeve ring 28 are used for sealing and wrapping the end of the outer sleeve ring 2 and the inner sleeve ring 3 away from the inner ring 12 and the outer ring 11, and the one-way exhaust sleeve ring 28 is used for sealing between the small ring end of the sealing ring piece 27 and the inner sleeve ring 3 to prevent the external water vapor from entering therebetween when the rotating shaft 4 does not rotate.

[0141] When the air suction blade group 33 rotates, the air blown by the air suction blade group 33 blows away the one-way exhaust ring 28, so that the air entering from the air inlet 25 flows out from the one-way exhaust ring 28, forming a negative pressure circulation.

[0142] In some embodiments, the one-way exhaust ring 28 is made of flexible rubber material, which can be passively deformed when blown to release the wrapping of the inner ring 3, forming a gap for air outlet, so that the air between the outer ring 2 and the inner ring 3 is discharged.

[0146] Embodiment 11:

[0147] Referring to Figures 9-13 , further, the embodiment provides a red mud thermal reaction material pressing device, which comprises the control bearing for high-temperature and high-humidity environment, and further comprises a rotating shaft 4, a mounting frame 5, a material pressing mechanism, a driving motor 71 and a movement control mechanism.

[0148] The rotating shaft 4 is provided with a key groove 41, and the key groove 41 is in sliding fit with the sliding key 121 of the control bearing; and the inner sleeve 3 is sleeved on the rotating shaft 4.

[0149] The control bearing is two groups, and the two groups of control bearings are arranged at the two ends of the rotating shaft 4, and the control bearing is supported and installed by the mounting frame 5.

[0150] The two groups of control bearings are installed in a high-temperature and high-humidity environment to support rotation of the two ends of the rotating shaft 4, the inner side of the control bearing is used to install the rotating shaft 4, and the outer side of the control bearing is used to install the control bearing as a whole on the mounting frame 5 to provide a position basis for rotation of the rotating shaft 4.

[0151] The material pressing mechanism comprises a material pressing plate 61, a fixed rod 62 and a rotation control assembly.

[0152] The fixed rod 62 is fixedly connected in the circumferential direction of the rotating shaft 4, and the length direction of the fixed rod 62 passes through the axis of the rotating shaft 4.

[0153] One end of the pressing plate 61 is rotatably installed at one end of the fixed rod 62 away from the rotating shaft 4, and the rotation center of the pressing plate 61 is parallel to the axis of the rotating shaft 4.

[0154] Among them, the pressing plate 61 is a plurality of groups, and one group of pressing plate 61 is rotatably connected with at least two groups of fixed rods 62 in the length direction of the rotating shaft 4.

[0155] The fixed rod 62 and the pressing plate 61 are rotatably connected, and the rotation control assembly controls the rotation of the pressing plate 61 between the pressing plates 61, that is, the relative angle between the pressing plate 61 and the fixed rod 62, so that the height of the liquid medicine in the sealed warehouse can be adapted by setting the angle of the pressing plate 61 relative to the fixed rod 62 without changing the installation height of the rotating shaft 4, so that the pressing plate 61 can maintain a parallel posture with the water surface when pressing the material, and the red mud can be pressed into the liquid medicine, improving the efficiency of the pressing material.

[0156] The rotation control assembly comprises a sliding sleeve 631, a rotating connecting rod 632, a pushing connecting rod 633 and an abutting sleeve 634.

[0157] The sliding sleeve 631 is sleeved on the surface of the fixed rod 62, one end of the rotating connecting rod 632 is rotatably connected with the surface of the pressing plate 61, and the other end is rotatably connected with the surface of the sliding sleeve 631.

[0158] The abutting sleeve 634 is slidably sleeved on the rotating shaft 4, and the sliding sleeve is arranged between the rotating rod and the control bearing, one end of the pushing connecting rod 633 is rotatably connected with the sliding sleeve 631, and the other end of the pushing connecting rod 633 is rotatably connected with the abutting sleeve 634.

[0159] The mounting frame 5 further comprises a limiting mechanism, and the limiting mechanism is used for limiting the movement of the sliding sleeve 631 in the axial direction of the rotating shaft 4.

[0160] The driving motor 71 is arranged at the end of the rotating shaft 4, the rotating shaft 4 and the driving motor 71 are slidably connected through the spline 72, and the movement control mechanism controls the movement of the rotating shaft 4 relative to the driving motor 71 in the axial direction.

[0161] The rotating link 632 and the pushing link 633 are respectively hinged to the 90° direction of the sliding sleeve 631. Due to the limitation of the limiting mechanism, when the rotating shaft 4 is controlled to move along the axis direction by the moving control mechanism, the abutting sleeve 634 does not move with the rotating shaft 4, and under the driving of the pushing link 633 hinged at the two ends of the abutting sleeve 634 and the sliding sleeve 631 respectively, the sliding sleeve 631 moves along the length direction of the fixed rod 62, and under the driving of the rotating link 632 hinged at the two ends of the sliding sleeve 631 and the surface of the pressing plate 61 respectively, the pressing plate 61 rotates with the sliding sleeve 631, so as to change the hinge angle between the pressing plate 61 and the fixed rod 62, so as to adjust the angle of the pressing plate 61, so as to adapt to the liquid level of the liquid. The rotating shaft 4 is controlled to move close or away by the moving control mechanism, so as to adjust the angle of the pressing plate 61 back and forth.

[0162] Embodiment 12:

[0166] The caliper 733 is only arranged at the two ends of the rotating disc 732. When the rotating shaft 4 rotates and drives the rotating disc 732 to rotate, the caliper 733 does not limit the rotation of the rotating disc 732. When it is necessary to adjust the angle of the pressing plate 61 by moving the rotating shaft 4, the caliper 733 is directly controlled to move by the moving push rod 731, the rotating disc 732 and the rotating shaft 4 fixedly arranged at the rotating disc 732 are indirectly driven to move along the axis of the rotating shaft 4 by the caliper 733, so as to control the rotation of the pressing plate 61. For the pressing mechanism installed in the closed cabin, only the rotating shaft 4 penetrates the side wall of the cabin, and other powered control structures do not need to be arranged in the cabin to adjust the angle of the pressing plate 61, so as to avoid unnecessary openings of the cabin and corrosion of other powered control mechanisms in high temperature and high humidity environment.

[0167] In some embodiments, the moving push rod 731 is realized by using existing linear motion devices, such as hydraulic push rod, pneumatic push rod or electric push rod.

[0171] The limiting block 51 is directly inserted into the limiting groove 635, when the abutting sleeve 634 rotates with the rotating shaft 4, the limiting block 51 does not limit the rotation of the limiting groove 635, at this time, the limiting groove 635 can rotate freely relative to the limiting block 51. When the rotating shaft 4 moves along the axial direction of the rotating shaft 4, one of the two side surfaces of the limiting groove 635 directly abuts against the limiting block 51, and the movement of the limiting block 51 is limited, so that the rotating shaft 4 and the abutting sleeve 634 move relatively along the axial direction of the rotating shaft 4, the push connecting rod 633 drives the sliding sleeve 631 to move on the fixed rod 62, and the rotating connecting rod 632 drives the pressing plate 61 to rotate, so that the angle of the pressing plate 61 is adjusted.
