[0021] The features and exemplary embodiments of various aspects of the utility model will be described in detail below. In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the utility model, rather than to limit the utility model. For those skilled in the art, the utility model can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the utility model by showing examples of the utility model.
[0022] like Figure 1 and Figure 2As shown, the utility model provides a horizontal reactor, which comprises a horizontal reactor body 1 with a horizontally extending axis, a sealing cylinder 2 and a stirring shaft 3. The head end of the sealing cylinder 2 is sealed and installed on the outer side of the end wall of the horizontal reactor body 1, and the stirring shaft 3 capable of circumferential rotation comprises a shaft stirring portion 31 and a shaft connecting portion 32 connected to each other, the shaft stirring portion 31 is located in the horizontal reactor body 1, and the shaft connecting portion 32 extends from the end wall of the horizontal reactor body 1, the sealing cylinder 2 is sleeved on the outer side of the shaft connecting portion 32, and the sealing cylinder 2 and the shaft connecting portion 32 are sealed by a first labyrinth sealing structure arranged therebetween, and a first sealing component 4 is also arranged therebetween between the sealing cylinder 2 and the shaft connecting portion 32, and the first labyrinth sealing structure is located between the end wall of the horizontal reactor body 1 and the first sealing component 4.
[0023] Specifically, the axis of the horizontal kettle body 1, the axis of the sealing cylinder 2 and the axis of the stirring shaft 3 extend horizontally and overlap. A mounting hole is provided at the end wall of the horizontal kettle body 1, and the stirring shaft 3 is inserted into the mounting hole. The head end of the sealing cylinder 2 is sealed and mounted on the outer side of the end wall of the horizontal kettle body 1 around the mounting hole. The first labyrinth sealing structure is located between the sealing cylinder 2 and the shaft body connecting portion 32, and the first labyrinth sealing structure is arranged around the shaft body connecting portion 32. The first sealing component 4 is located between the sealing cylinder 2 and the shaft body connecting portion 32, and the first sealing component 4 is arranged around the shaft body connecting portion 32.
[0024] In this embodiment, the sealing cylinder 2 is sealed and installed on the outer side of the end wall of the horizontal kettle body 1 to prevent external gas from entering the gap between the end wall of the horizontal kettle body 1 and the stirring shaft 3 through the gap between the sealing cylinder 2 and the horizontal kettle body 1. Moreover, there is no relative movement between the sealing cylinder 2 and the horizontal kettle body 1, so a good sealing performance can be ensured between the sealing cylinder 2 and the horizontal kettle body 1. The shaft body connection part 32 of the stirring shaft 3 is located in the sealing cylinder 2. Although the shaft body connection part 32 of the stirring shaft 3 can rotate in the sealing cylinder 2, the shaft body connection part 32 of the stirring shaft 3 and the sealing cylinder 2 are double-sealed through the first labyrinth sealing structure and the first sealing component 4, preventing external gas from entering the gap between the end wall of the horizontal kettle body 1 and the stirring shaft 3 through the gap between the sealing cylinder 2 and the stirring shaft 3. Therefore, the gap between the end wall of the horizontal kettle body 1 and the stirring shaft 3 is effectively sealed, which improves the sealing performance of the horizontal reactor.
[0025] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, there are multiple first sealing components 4; and along the axial direction of the stirring shaft 3, all the first sealing components 4 are tightly attached to the end of the sealing cylinder 2 in sequence.
[0026] Specifically, a first mounting groove is provided on the inner side of the end of the sealing cylinder 2, and the first mounting groove is recessed from the inner side of the sealing cylinder 2 toward the outer side of the sealing cylinder 2. The first mounting groove surrounds the shaft connecting portion 32. All the first sealing components 4 are filled in the first mounting groove, and the plurality of first sealing components 4 are closely attached in sequence, which helps to improve the sealing performance of the horizontal kettle body 1. Of course, the first mounting groove has only one bottom wall and side wall, and the side wall of the first mounting groove is located between its bottom wall and the first labyrinth sealing structure. Therefore, the first mounting groove is open toward the axial outer side of the sealing cylinder 2 to facilitate the disassembly and assembly of the first sealing component 4.
[0027] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the horizontal reactor further comprises a pressing device 5 capable of pressing all first sealing components 4 toward the horizontal reactor body 1 .
[0028] Specifically, the rotation of the stirring shaft 3 may cause the first sealing component 4 to loosen, thereby reducing the sealing effect. The pressing device 5 can press the first sealing component 4 between the sealing cylinder 2 and the shaft connecting portion 32 to prevent the first sealing component 4 from loosening.
[0029] In some embodiments, the clamping device 5 is located between the sealing cylinder 2 and the bearing seat 7. The shaft connecting portion 32 extends from the sealing cylinder 2 and is connected to the bearing seat 7. Of course, the other side of the bearing seat 7 is a driving motor, which is connected to the shaft connecting portion 32 through the bearing seat 7.
[0030] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the clamping device 5 includes a limiting device 51 and a plurality of elastic extrusion rings 52. The extrusion ring 52 is sleeved on the outer side of the shaft connecting portion 32, the first sealing component 4 is located between the extrusion ring 52 and the first labyrinth seal structure, and all the extrusion rings 52 are closely attached to each other in sequence along the axial direction of the stirring shaft 3, the limiting device 51 is fixedly installed at the end of the sealing cylinder 2, and the limiting device 51 squeezes all the extrusion rings 52 toward the first sealing component 4.
[0031] Specifically, the extrusion rings 52 are arranged in sequence along the axial direction of the stirring shaft 3, and two adjacent extrusion rings 52 are squeezed and fitted to each other. And the extrusion ring 52 closest to the sealing cylinder 2 is squeezed on the first sealing component 4 located on the outermost side. The extrusion ring 52 is limited between the sealing cylinder 2 and the limiting device 51 by the limiting device 51. The extrusion ring 52 is in a state of radially and axially compressed, and the extrusion ring 52 with a tendency to restore deformation squeezes the first sealing component 4. The extrusion ring 52 can be fixedly connected or movably connected to the limiting device 51, and the utility model does not limit it. The extrusion ring 52 can be made of common rubber material or common plastic material with elasticity, and the utility model does not limit it.
[0032] like Figure 1 and Figure 2 As shown, in some embodiments of the utility model, the limiting device 51 includes a connecting tube 53 and an end plate 54, the connecting tube 53 is sleeved on the outside of all the extrusion rings 52, the end of the connecting tube 53 facing the horizontal kettle body 1 is fixedly connected to the end of the sealing tube 2, the end plate 54 surrounds the stirring shaft 3, and the end plate 54 is fixedly connected to the end of the connecting tube 53 facing away from the kettle body, all the extrusion rings 52 are located between the end plate 54 and the first sealing component 4, and the end plate 54 squeezes all the extrusion rings 52 toward the first sealing component 4.
[0033] Specifically, the head end of the connecting cylinder 53 and the end of the sealing cylinder 2 are axially opposite to each other. The outer ring of the head end of the connecting cylinder 53 is provided with a second flange plate 55, and the outer ring of the end of the sealing cylinder 2 is provided with a third flange plate 24. The second flange plate 55 and the third flange plate 24 are fixedly connected by a plurality of bolt assemblies, and all the bolt assemblies are distributed around the shaft body connection portion 32. Of course, the bolt assembly includes bolts, nuts and gaskets. An annular rubber sealing gasket can also be arranged between the third flange plate 24 and the second flange plate 55. Since the bolt assembly is located on the third flange plate 24 and the second flange plate 55, that is, the bolt assembly is located on the radial outer side of the connecting cylinder 53 and the sealing cylinder 2, it is convenient to check whether the bolt assembly is loose. All the extrusion rings 52 are located between the connecting cylinder 53 and the shaft body connection portion 32. Of course, the connecting cylinder 53 can also radially extrude the extrusion ring 52 to increase the deformation of the extrusion ring 52, thereby increasing the axial pressure of the extrusion ring 52. The end plate 54 is connected to the end of the connecting cylinder 53. The end plate 54 and the connecting cylinder 53 can be integrally formed. The end plate 54 is annular and is distributed around the shaft connecting portion 32. The radial outer side of the end plate 54 is sealed to the end of the connecting tube 53. The inner diameter of the end plate 54 is slightly larger than the diameter of the shaft connecting portion 32. All the extrusion rings 52 are located between the end plate 54 and the first sealing component 4. The end plate 54 applies an extrusion force to the extrusion ring 52 toward the sealing tube 2.
[0034] In some embodiments, the connecting tube 53 includes two C-shaped parts, which are spliced to form a cylindrical connecting tube 53 for easy disassembly. The end plate 54 also includes two C-shaped parts, which are connected to the two parts of the connecting tube 53 in a one-to-one correspondence, and the two parts of the end plate 54 are spliced to form a circular end plate 54.
[0035] In some embodiments, the extrusion ring 52 is configured to be C-shaped with a notch. When installing the extrusion ring 52, the extrusion ring 52 is simply sleeved onto the shaft connecting portion 32 from the notch. Therefore, the C-shaped extrusion ring 52 is easy to install. Of course, the notches of two adjacent extrusion rings 52 can be staggered.
[0036] In some embodiments, the extrusion ring 52 is a hollow structure, and an air filling tube 56 is provided on the extrusion ring 52. The end of the air filling tube 56 is connected to the inside of the extrusion ring 52, and the head end of the extrusion ring 52 extends from the limit device 51 (such as the connecting tube 53 or the end plate 54). On-site personnel can use an air filling device to connect the head end of the air filling tube 56 to inflate the extrusion ring 52. A one-way valve or an airtight core is also provided in the air filling tube 56 to prevent gas from flowing out of the extrusion ring 52. By inflating the extrusion ring 52, the pressure of the extrusion ring 52 on the first sealing component 4 can be increased. For example, when the first sealing component 4 is displaced due to the friction of the shaft connecting part 32, which causes the first sealing component 4 to loosen, gas can be filled into the extrusion ring 52 to increase the pressure on the extrusion ring 52 to prevent the first sealing component 4 from loosening.
[0037] like Figure 1 and Figure 2 As shown, in some embodiments of the utility model, a plurality of first sealing blocks 33 are provided on the side wall of the shaft connecting portion 32 and are spaced apart along the axial direction of the stirring shaft 3, and the first sealing blocks 33 circumferentially surround the shaft connecting portion 32; a plurality of first sealing grooves 21 are provided on the inner wall of the sealing cylinder 2 and are spaced apart along the axial direction of the stirring shaft 3, and the first sealing grooves 21 circumferentially surround the shaft connecting portion 32, and all the first sealing blocks 33 are movably embedded in all the first sealing grooves 21 one by one, and the surfaces of the first sealing blocks 33 are fitted with the groove walls of the corresponding first sealing grooves 21, and all the first sealing blocks 33 and all the first sealing grooves 21 cooperate to form a first labyrinth sealing structure.
[0038] Specifically, the first sealing block 33 protrudes radially outward on the shaft body connecting portion 32, and the first sealing groove 21 is recessed from the inner wall of the sealing cylinder 2 to the outer wall of the sealing cylinder 2. The size of the first sealing groove 21 is slightly larger than the size of the first sealing block 33, so the first sealing block 33 is movably embedded in the first sealing groove 21, and the surface of the first sealing block 33 is in contact with the groove wall of the first sealing groove 21. When the stirring shaft 3 rotates circumferentially, the first sealing block 33 can rotate circumferentially in the first sealing groove 21. An appropriate amount of sealing oil or lubricating oil can be filled between the first sealing block 33 and the first sealing groove 21 to improve the sealing performance and reduce friction. A bending gap or a labyrinth gap with multiple bending parts is formed between the first sealing block 33 and the first sealing groove 21. The bending gap is similar to a labyrinth, and the external gas needs to turn at a large angle multiple times before it can enter the horizontal kettle body 1, so the first labyrinth sealing structure can improve the sealing performance.
[0039] In some other embodiments, the first sealing block 33 can be arranged on the inner side of the sealing cylinder 2, the first sealing groove 21 can be arranged on the outer side of the shaft connecting portion 32, and the first sealing block 33 is movably embedded in the first sealing groove 21 to form a first labyrinth sealing structure.
[0040] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the head end of the sealing cylinder 2 and the outer side of the end wall of the horizontal kettle body 1 are sealed by a second labyrinth sealing structure to enhance the sealing between the horizontal kettle body 1 and the sealing cylinder 2 .
[0041] like Figure 1 and Figure 2 As shown, in some embodiments of the utility model, a first flange plate 22 is provided on the outer side of the head end of the sealing cylinder 2, and a plurality of second sealing grooves 23 surrounding the shaft body connecting portion 32 are provided on the side of the first flange plate 22 facing the horizontal kettle body 1, and all the second sealing grooves 23 are distributed at intervals along the radial direction of the stirring shaft 3. A plurality of second sealing blocks 11 surrounding the stirring shaft 3 are provided on the outer side of the end wall of the horizontal kettle body 1, and all the second sealing blocks 11 are distributed at intervals along the radial direction of the stirring shaft 3, and all the second sealing blocks 11 are embedded in all the second sealing grooves 23 one by one, and the surface of the second sealing block 11 is in contact with the groove wall of the corresponding second sealing groove 23, and all the second sealing blocks 11 and all the second sealing grooves 23 cooperate to form a second labyrinth sealing structure.
[0042] Specifically, the second sealing block 11 protrudes outward from the outer side of the end wall of the horizontal kettle body 1, and the second sealing groove 23 is recessed from the side of the first flange plate 22 facing the horizontal kettle body 1 to the side facing away from the kettle body. The size of the second sealing groove 23 is slightly larger than the size of the second sealing block 11, so the second sealing block 11 is fixedly embedded in the second sealing groove 23, and the surface of the second sealing block 11 fits the groove wall of the second sealing groove 23. An appropriate amount of sealing oil or lubricating oil can be filled between the second sealing block 11 and the second sealing groove 23 to improve the sealing performance. A bending structure similar to a maze is formed between the second sealing block 11 and the second sealing groove 23. The external gas needs to turn at a large angle for many times before it can enter the horizontal kettle body 1, so the second labyrinth sealing structure can improve the sealing performance. The first flange plate 22 and the sealing cylinder 2 can be integrally formed or welded. Of course, in this embodiment, the sealing cylinder 2 is installed on the horizontal kettle body 1 with a detachable structure, which is convenient for disassembly and assembly.
[0043] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, a second sealing component 6 is further provided between the first flange plate 22 and the end wall of the horizontal kettle body 1, the second sealing component 6 surrounds the shaft connection portion 32, the second labyrinth sealing structure is located between the shaft connection portion 32 and the second sealing component 6, and the second sealing component 6 is located at the radial outer edge of the first flange plate 22.
[0044] Specifically, the radial outer edge of the first flange plate 22 is thinner than other positions, and becomes thinner from the side of the first flange plate 22 facing the horizontal kettle body 1 to the side facing away from the horizontal kettle body 1, so a second mounting groove is formed between the first flange plate 22 and the end wall of the horizontal kettle body 1, and the second mounting groove surrounds the sealing cylinder 2. The second sealing component 6 is filled in the second mounting groove to increase the sealing between the sealing cylinder 2 and the horizontal kettle body 1 and facilitate replacement. Of course, the number of the second sealing components 6 can be multiple, and all the second sealing components 6 are sequentially close to the radial direction of the stirring shaft 3.
[0045] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the first sealing component 4 is a packing, and the second sealing component 6 is a packing. The packing has good sealing performance and is easy to fill. Of course, the first sealing component 4 and the second sealing component 6 can also be sealing components such as annular rubber rings.
[0046] In some embodiments, the sealing cylinder 2 includes two parts, each part is C-shaped, and the two C-shaped parts are spliced to form a cylindrical sealing cylinder 2. A sealing gasket can also be arranged between the two C-shaped parts to improve the sealing performance. Of course, a labyrinth sealing structure can also be arranged between the two C-shaped parts to enhance the sealing performance. The sealing cylinder 2 is arranged in such a splicing structure for easy disassembly and assembly.
