DETAILED DESCRIPTION

[0027] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below in conjunction with the drawings of the specification.

[0028] Example 1 Reference Figures 1-13 For the first embodiment of the present application, the embodiment provides a center cylinder separation structure for acetic acid pressurized gasifier, which realizes the effect of faster and more convenient installation and removal of the center cylinder composed of the center arc plate 12, comprising a mounting mechanism, which comprises a gasifier body 10 and a feeding pipe 11, the inner cavity of the gasifier body 10 is provided with a center arc plate 12 at the middle of the upper end, the inner ring of the upper end opening of the gasifier body 10 is provided with an inner ring sliding groove 13, a plurality of first arc-shaped sliding blocks 14 are slidingly arranged in the inner cavity of the inner ring sliding groove 13, two second arc-shaped sliding blocks 15 are abutted in the plurality of first arc-shaped sliding blocks 14, a third arc-shaped sliding block 16 is abutted between the two second arc-shaped sliding blocks 15, a plug-in assembly 17 for labor-saving installation and removal is arranged between the first arc-shaped sliding block 14, the second arc-shaped sliding block 15 and the third arc-shaped sliding block 16, and a quick plug-in assembly 18 for quick positioning and installation is arranged on the plurality of first arc-shaped sliding blocks 14; A fixing mechanism, comprising a plurality of horizontal sliding grooves 20 arranged in the inner cavity of the inner ring sliding groove 13, a limiting assembly 21 is arranged in each of the plurality of horizontal sliding grooves 20, and the limiting assembly 21 is used for quickly fixing and limiting the feeding pipe 11 and quickly unlocking; A quick disassembly mechanism, comprising a plurality of L-shaped horizontal grooves 30 arranged on the inner ring sidewall of the inner ring sliding groove 13, a plurality of reverse push assemblies 31 are arranged in the inner cavities of the plurality of L-shaped horizontal grooves 30, and the reverse push assembly 31 is used for separating the feeding pipe 11 and the plurality of first arc-shaped sliding blocks 14, the two second arc-shaped sliding blocks 15 and the third arc-shaped sliding block 16 from the gasifier body 10 in the reverse direction, thereby facilitating disassembly.

[0029] Specifically, the plurality of central arc plates 12 can be mutually attached to form a cylinder, referred to herein as a central cylinder, and the inclination angles of the two side surfaces of each central arc plate 12 corresponding to the first arc-shaped sliding block 14 are consistent. Since the upper opening of the gasification furnace body 10 is circular, when the plurality of first arc-shaped sliding blocks 14 are inserted into the inner ring sliding groove 13 in equal parts, the last installed first arc-shaped sliding block 14 will be more difficult to install. Therefore, the second arc-shaped sliding block 15 and the third arc-shaped sliding block 16 are arranged at the position where the central cylinder is finally assembled, and the inclination angle of the third arc-shaped sliding block 16 is opposite to that of the first arc-shaped sliding block 14. The inclination angle of one side of the second arc-shaped sliding block 15 is consistent with that of the first arc-shaped sliding block 14, and the inclination angle of the other side of the second arc-shaped sliding block 15 is consistent with that of the third arc-shaped sliding block 16. Thus, the last installed part of the central cylinder can be more conveniently inserted into the inner ring sliding groove 13 for installation.

[0030] Further, the plug-in assembly 17 includes a first inclined surface 171 arranged on the two side surfaces of the plurality of first arc-shaped sliding blocks 14. The first inclined surface 171 on each of the two side surfaces of the first arc-shaped sliding block 14 is arranged to be outwardly eight-shaped. The two second arc-shaped sliding blocks 15 and the first arc-shaped sliding block 14 abutting one side surface are arranged as the first inclined surface 171. The second arc-shaped sliding block 15 and the third arc-shaped sliding block 16 abutting one side surface are arranged as a second inclined surface 172, but the inclination angle of the second inclined surface 172 is greater than that of the first inclined surface 171. The third arc-shaped sliding block 16 is provided with a third inclined surface 173 on the two side surfaces, which is inwardly eight-shaped. The third inclined surface 173 and the second inclined surface 172 are mutually attached and abut. The third arc-shaped sliding block 16 is provided with a fast plug-in inclined surface 174 at the plug-in end of the inner ring sliding groove 13. The fast plug-in inclined surface 174 is used to reduce the resistance when the third arc-shaped sliding block 16 is inserted into the inner cavity of the inner ring sliding groove 13.

[0031] The upper end of the outwardly inclined surface of the fast plug-in inclined surface 174 has a vertical plate, which can better insert the third arc-shaped sliding block 16 into the inner cavity of the inner ring sliding groove 13, and also stably connect the third arc-shaped sliding block 16 with the inner ring sliding groove 13.

[0032] Preferably, the plurality of quick insertion assemblies 18 comprise an arc-shaped slot 181 initially formed in the inner ring of the plurality of first arc-shaped sliding blocks 14, the arc-shaped slot 181 is formed through the middle of the inner wall on one side of the inner ring sliding groove 13, an L-shaped vertical slot 182 is formed in the inner cavity of the arc-shaped slot 181, an L-shaped sliding rod 183 is slidably arranged in the inner cavity of the L-shaped vertical slot 182, a bottom push plate 184 is fixedly arranged at the lower end of the L-shaped sliding rod 183, the upper surface of the bottom push plate 184 abuts against the lower surface of the inlet pipe 11, a compression spring 185 is elastically connected to the middle of the lower surface of the bottom push plate 184, a spring groove 186 is arranged outside the compression spring 185, the spring groove 186 is formed in the middle of the bottom surface of the inner cavity of the first arc-shaped sliding block 14, and the plurality of quick insertion assemblies 18 further comprise a plurality of vertical insertion slots 187 formed in the inner ring side wall of the inner ring sliding groove 13, the positions of the plurality of vertical insertion slots 187 correspond to the positions of the protruding parts of the upper ends of the plurality of L-shaped sliding rods 183 one by one, and a vertical insertion rod 188 is inserted and arranged in the inner cavity of each of the plurality of vertical insertion slots 187, and the upper surface of the vertical insertion rod 188 is fixedly arranged with the middle of the lower surface of the protruding end of the upper part of the L-shaped sliding rod 183.

[0033] It should be noted that the middle of each of the first arc-shaped sliding block 14, the second arc-shaped sliding block 15 and the third arc-shaped sliding block 16 is provided with the quick insertion assembly 18, and the bottom push plate 184 in the normal state is located at the middle of the L-shaped vertical slot 182 and downward, so that when the first arc-shaped sliding block 14, the second arc-shaped sliding block 15 and the third arc-shaped sliding block 16 are inserted into the inner cavity of the inner ring sliding groove 13, the vertical insertion rod 188 can be inserted into the upper end opening of the vertical insertion slot 187 formed in the inner ring of the inner ring sliding groove 13, and then the first arc-shaped sliding block 14, the second arc-shaped sliding block 15 and the third arc-shaped sliding block 16 preliminarily limit the central arc plate 12, and then the lower end of the inlet pipe 11 is inserted into the arc-shaped slot 181, and the weight of the inlet pipe 11 presses the bottom push plate 184 and the L-shaped sliding rod 183 and the vertical insertion rod 188 downward, so that the vertical insertion rod 188 is further inserted into the vertical insertion slot 187 for limiting, and it should be noted that the width of each central arc plate 12 is less than the diameter of the inlet of the gasifier body 10 and less than the inner diameter of the circular ring formed by the first arc-shaped sliding block 14, so that when the plurality of central arc plates 12 are sequentially placed in the inner cavity of the gasifier body 10, they will not be blocked.

[0034] In use, first, the plurality of central arc plates 12 are sequentially placed in the inner cavity of the gasifier body 10, and after each central arc plate 12 is placed from the inlet of the gasifier body 10, the arc-shaped protruding part at one end of the outer arc surface of the first arc-shaped sliding block 14 is inserted into the inner cavity of the inner ring sliding groove 13, and before insertion, the vertical insertion rod 188 is aligned with the vertical insertion slot 187 on the inner ring sliding groove 13, and after the position is confirmed, the first arc-shaped sliding block 14 is inserted and limited with the inner ring sliding groove 13.

[0035] When the first arc-shaped slider 14 is inserted, the two center arc plates 12 provided with the second arc-shaped slider 15 are sequentially placed in, and are installed in the order of the first inclined surface 171 on one side of the first arc-shaped slider 14 and the first inclined surface 171 with the same inclination angle as the first arc-shaped slider 14. Finally, the center arc plate 12 provided with the third arc-shaped slider 16 at the upper end is placed in the inner cavity of the gasification furnace body 10. Since the inclination angle of the third inclined surface 173 on both sides of the third arc-shaped slider 16 is opposite to that of the second inclined surface 172 and the first inclined surface 171, the third arc-shaped slider 16 can be installed more easily. In addition, the protruding part of the third arc-shaped slider 16 inserted into the inner ring sliding groove 13 is provided with a quick insertion inclined surface 174, so that the insertion process is more labor-saving. Finally, when all the first arc-shaped slider 14, the second arc-shaped slider 15 and the third arc-shaped slider 16 are installed, the center cylinder composed of the three achieves preliminary installation and positioning.

[0036] Next, the pipeline lower end of the feeding pipe 11 is inserted into the arc-shaped slot 181 in the inner ring of the first arc-shaped slider 14, the second arc-shaped slider 15 and the third arc-shaped slider 16, so that the feeding pipe 11 is pressed downward by its own weight to push the bottom push plate 184, and the bottom push plate 184 drives the L-shaped sliding rod 183 to move downward along the L-shaped vertical slot 182, and then the L-shaped sliding rod 183 drives the vertical insertion rod 188 to move downward synchronously, so as to compress the compression spring 185, and then the vertical insertion rod 188 preliminarily inserted into the vertical insertion slot 187 is further inserted into the inner cavity of the vertical insertion slot 187. Then, the feeding pipe 11 is pressed again to continue moving downward, so as to trigger the limiting component 21 of the fixing mechanism to quickly fix and limit the feeding pipe 11 in the horizontal sliding slot 20. Thus, the installation is completed.

[0037] Example 2 Reference Figures 1-13For the second embodiment of the application, unlike the previous embodiment, the embodiment provides a fixing mechanism for the center cylinder separation structure of the acetic acid pressurized gasifier, which solves the problem of inconvenient disassembly when cleaning the center arc plate 12. It includes a plurality of limiting assemblies 21, including a lower push block 211 fixedly arranged in the middle of the lower surface of the vertical insertion rod 188, a horizontal sliding rod 212 abuttingly arranged at the lower end of the lower push block 211, the horizontal sliding rod 212 being slidingly arranged in the inner cavity of the horizontal sliding groove 20, and a fixed insertion groove 213 being arranged at one end of the horizontal sliding rod 212 located at the opening end of the horizontal sliding groove 20, the fixed insertion groove 213 being opened on the lower end outer ring surface of the inlet pipe 11, a plurality of horizontal sliding rods 212 being fixedly arranged at the middle of the end away from the fixed insertion groove 213, a pull rope 214 being fixedly arranged at the other end of the horizontal sliding rod 212, a plug pin 215 being movably penetrated through the outer ring side wall of the inner ring sliding groove 13, a wire wheel 216 being arranged at the lower end of the connection between the pull rope 214 and the plug pin 215 for changing the moving direction of the pull rope 214, the wire wheel 216 being rotationally arranged at the innermost end of the inner cavity of the horizontal sliding groove 20, a first ring plate 217 being arranged at the upper end of the plug pin 215, a plurality of pull rings 218 being arranged on the upper surface of the first ring plate 217, the lower end of each lower push block 211 and the side surface of the horizontal sliding rod 212 abuttingly arranged being inclined, and the abutting surface of the horizontal sliding rod 212 and the lower push block 211 also being inclined, so that the lower push block 211 and the horizontal sliding rod 212 can abut each other to push the horizontal sliding rod 212 into the fixed insertion groove 213 to fix the inlet pipe 11.

[0038] Specifically, the lower end of the lower push block 211 is provided with an opening slot in the middle, which is used to avoid the situation that the pull rope 214 is pressed during the downward movement. The width of the inner cavity of the horizontal sliding groove 20 at the front end is greater than that at the rear end, and the rear end of the horizontal sliding rod 212 in the normal state is located at the width transition position of the inner cavity of the horizontal sliding groove 20. This position can make the lower end inclined surface of the lower push block 211 abut with the inclined surface of the horizontal sliding rod 212 when the lower push block 211 moves downward with the vertical insertion rod 188, so as to push the horizontal sliding rod 212 out and just clamped into the fixed insertion groove 213 opened on the lower end outer ring surface of the inlet pipe 11 for fixation.

[0039] In use, when the lower end of the inlet pipe 11 is inserted into the arc-shaped slot 181 and the bottom push plate 184 is pressed down by its own weight, the L-shaped slide rod 183 drives the vertical insertion rod 188 to move downward synchronously, and the lower push block 211 on the lower surface of the vertical insertion rod 188 moves downward. Since the side of the lower end of the lower push block 211 that is in contact with the horizontal slide rod 212 is a slope, and the corresponding contact surface of the horizontal slide rod 212 is also a slope, during the continuous downward movement of the inlet pipe 11, the slope of the lower push block 211 will extrude the slope of the horizontal slide rod 212 during the continuous downward pressing of the lower push block 211 by the vertical insertion rod 188, thereby pushing the horizontal slide rod 212 to slide along the inner cavity of the horizontal sliding groove 20 towards the inlet pipe 11. At this time, the front end of the horizontal slide rod 212 is pushed out of the inner cavity of the horizontal sliding groove 20 and inserted into the fixed insertion slot 213 on the lower end of the inlet pipe 11, completing the quick fixing and limiting of the inlet pipe 11, and the opening slot at the lower end of the lower push block 211 effectively avoids the pull rope 214, preventing the pull rope 214 from being pressed during the downward movement and affecting the unlocking of the pull rope 214 pulling the horizontal slide rod 212.

[0040] When unlocking is needed, the operator pulls the pull ring 218 on the upper surface of the first ring plate 217 upwards, and the first ring plate 217 drives the plurality of insertion pins 215 to move upwards synchronously, and the insertion pins 215 pull the pull rope 214 around the wire wheel 216. Due to the action of the wire wheel 216 at the innermost end of the horizontal sliding groove 20, the pull rope 214 changes the direction of movement, thereby pulling the horizontal slide rod 212 to slide away from the fixed insertion slot 213, so that the horizontal slide rod 212 is pulled out of the fixed insertion slot 213, and the fixing and limiting of the inlet pipe 11 is released. At this time, the compressed compression spring 185 in the quick insertion assembly 18 is elastically reset, pushing the bottom push plate 184 to move upwards, driving the L-shaped slide rod 183 and the vertical insertion rod 188 to move upwards synchronously, and the vertical insertion rod 188 returns to the position of the opening of the inner cavity of the vertical insertion slot 187, but the vertical insertion rod 188 does not disengage from the vertical insertion slot 187 at this time, but continues to limit the first arc-shaped slide block 14, the second arc-shaped slide block 15, the third arc-shaped slide block 16 and the corresponding central arc plate 12. During the reverse pulling of the horizontal slide rod 212, the lower push block 211 is also pushed in the reverse direction, thereby pushing the vertical insertion rod 188 to move upwards.

[0041] Example 3 Reference Figures 1-13Figure, the third embodiment of the present application, unlike the previous embodiment, this embodiment provides a quick release mechanism for the center cylinder separation structure of the acetic acid pressurized gasifier, which solves the problem of complicated disassembly of the center arc plate 12, which includes a plurality of L-shaped transverse grooves 30 arranged on one side of a plurality of vertical insertion slots 187, and the plurality of L-shaped transverse grooves 30 are provided with two openings, one opening is communicated with the inner cavity of the vertical insertion slot 187, and the other opening is communicated with the inner cavity of the inner ring sliding groove 13, a plurality of reverse pushing assemblies 31 include an L-shaped sliding plate 311 slidingly arranged in the inner cavity of the L-shaped transverse groove 30, one end of the L-shaped sliding plate 311 protrudes out of the L-shaped transverse groove 30 and enters the inner cavity of the vertical insertion slot 187, and the lower end of the vertical insertion rod 188 is in abutment with the outer ring surface, the second ring plate 312 is fixedly arranged at one end of the L-shaped sliding plate 311 located at the other opening of the L-shaped transverse groove 30, and the second ring plate 312 is slidingly arranged in the inner cavity of the inner ring sliding groove 13, a tension spring 313 is arranged between the upper surface of the L-shaped sliding plate 311 and the inner cavity of the L-shaped transverse groove 30, for reversely pulling the L-shaped sliding plate 311, and then reversely pushing the inlet pipe 11 and the plurality of center arc plates 12 to pop up.

[0042] Specifically, when the vertical insertion rod 188 is inserted into the vertical insertion slot 187, it will initially abut with the L-shaped sliding plate 311, at this time the outer ring protruding portion of the first arc-shaped sliding block 14, the second arc-shaped sliding block 15 and the third arc-shaped sliding block 16 inserted into the inner ring sliding groove 13 all abut with the second ring plate 312, thereby enabling the vertical insertion rod 188 to push the L-shaped sliding plate 311 to move downward synchronously, thereby stretching the tension spring 313 to store energy, and when the inlet pipe 11 is inserted, it will pull the tension spring 313 to a preliminary energy storage position, and as the inlet pipe 11 is fixedly moved downward again, the tension spring 313 is in the final energy storage position, then when the horizontally sliding rod 212 fixedly limited is pulled out, the instantaneous pulling force of the tension spring 313 will make the inlet pipe 11 and the first arc-shaped sliding block 14, the second arc-shaped sliding block 15 and the third arc-shaped sliding block 16 pop up to the preliminary energy storage position, and then after the inlet pipe 11 is pulled out, the first arc-shaped sliding block 14, the second arc-shaped sliding block 15 and the third arc-shaped sliding block 16 are pushed in the opposite direction by the compression spring 185, so that the upper end of the first arc-shaped sliding block 14, the second arc-shaped sliding block 15 and the third arc-shaped sliding block 16 protrudes out of the upper opening of the inner ring sliding groove 13, making it more convenient to disassemble.

[0043] In use, when the first arc-shaped slider 14, the second arc-shaped slider 15 and the third arc-shaped slider 16 are inserted into the inner ring sliding groove 13, the lower surfaces of the outer ring protruding portions thereof are in abutment with the second ring plate 312; then, when the vertical insertion rod 188 is inserted into the vertical insertion slot 187, the preliminary abutment is formed with one end of the L-shaped sliding plate 311. When the feeding pipe 11 is inserted into the arc-shaped slot 181 and the bottom push plate 184 is pressed downward, the L-shaped sliding rod 183 drives the vertical insertion rod 188 to move downward synchronously, the vertical insertion rod 188 pushes the L-shaped sliding plate 311 to slide downward along the inner cavity of the L-shaped horizontal slot 30, at this time, the tensile spring 313 between the upper surface of the L-shaped sliding plate 311 and the upper surface of the inner cavity of the L-shaped horizontal slot 30 is gradually stretched and stored.

[0044] When the feeding pipe 11 is disassembled, the operator pulls the first ring plate 217 through the pull ring 218, so that the horizontal sliding rod 212 is pulled out of the fixed insertion slot 213, and the fixed limiting of the feeding pipe 11 is released. At this time, the tensile spring 313 in the final storage state releases the elastic potential energy instantaneously, generates a reverse pulling force to pull the L-shaped sliding plate 311 to slide upward along the inner cavity of the L-shaped horizontal slot 30, on one hand, the L-shaped sliding plate 311 pushes the vertical insertion rod 188 to move upward through the abutment with the vertical insertion rod 188, on the other hand, the L-shaped sliding plate 311 drives the second ring plate 312 to move upward synchronously, the second ring plate 312 applies an upward pushing force to the outer ring protruding portions of the first arc-shaped slider 14, the second arc-shaped slider 15 and the third arc-shaped slider 16, and the feeding pipe 11 and the arc-shaped sliders are collectively bounced upward to the preliminary storage position. Then, the compressed compression spring 185 in the quick insertion assembly 18 is further elastically reset, pushes the bottom push plate 184, the L-shaped sliding rod 183 and the vertical insertion rod 188 to move upward continuously, the vertical insertion rod 188 drives the arc-shaped sliders to continue to move upward, and finally the upper ends of the first arc-shaped slider 14, the second arc-shaped slider 15 and the third arc-shaped slider 16 protrude out of the upper opening of the inner ring sliding groove 13.
