[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-5As shown, a solid removal device for high solid content catalytic slurry includes a support bottom plate 1, a processing barrel 2 and a sealing cover 3: The outer wall of the top end of the support bottom plate 1 is provided with a processing barrel 2, and the outer wall of the top end of the processing barrel 2 is fitted with a sealing cover 3. A filter and solid removal mechanism is arranged inside the processing barrel 2, a portable cleaning mechanism is arranged on the side of the filter and solid removal mechanism, and an auxiliary solid removal mechanism is arranged on the side of the portable cleaning mechanism. The filter and solid removal mechanism includes a limit filter plate 41, a positioning support frame 42, a driving motor 43, a transmission shaft 44 and a limit scraper 45. The limit filter plate 41 is installed on the inner wall of the side of the processing barrel 2, the positioning support frame 42 is arranged on the outer wall of the top end of the sealing cover 3, the driving motor 43 is arranged on the outer wall of the top end of the positioning support frame 42, the driving motor 43 is connected to the outer wall of the top end of the transmission shaft 44, and a limit scraper 45 is arranged on the outer wall of the side of the transmission shaft 44 at the bottom position; As shown in the instruction manual appendix Figure 1 As shown, a feed hopper is conductively installed on the outer wall of the top end of the sealing cover 3. When solid removal treatment is required for the catalytic slurry stock solution, first, the catalytic slurry stock solution to be solid-removed needs to be poured into the inside of the processing barrel 2 through the feed hopper. Here, it should be noted that the limit filter plate 41 is set as a porous structure. Due to the setting of the limit filter plate 41, when the catalytic slurry stock solution to be solid-removed passes through the limit filter plate 41, the internal solid impurities will be automatically isolated above the limit filter plate 41. When it is necessary to accelerate the solid removal rate of the catalytic slurry stock solution, only the driving motor 43 needs to be turned on. After the driving motor 43 is turned on, it will automatically drive the transmission shaft 44 to rotate and then drive the limit scraper 45 to rotate. Subsequently, when the limit scraper 45 rotates, it will automatically push and rotate the solid impurities accumulated above the limit filter plate 41. At the same time, the rotation speed of the catalytic slurry stock solution is accelerated by the horizontal rotation method, so as to achieve the effect of accelerating solid removal on the basis of clearing the blockage of the limit filter plate 41 and accelerating the rotation speed of the catalytic slurry stock solution.

[0024] The limit scraper 45 is set in an "L" shape, and the outer wall of the bottom end of the limit scraper 45 is fitted with the outer wall of the top end of the limit filter plate 41, and the outer wall of the side of the limit scraper 45 is fitted with the inner wall of the side of the processing barrel 2; Through the above setting, when the limit scraper 45 rotates, on the one hand, it can push and rotate the solid impurities accumulated above the limit filter plate 41, thereby avoiding the phenomenon that the impurities block the limit filter plate 41 and cannot be filtered out. On the other hand, when the limit scraper 45 rotates, it can also scrape off part of the catalytic slurry stock solution remaining on the inner wall of the processing barrel 2 and continue to participate in the solid removal treatment.

[0025] The portable cleaning mechanism includes a limit support frame 51, a control motor 52 and a reciprocating lead screw 53. A limit support frame 51 is provided on the outer wall of the top end of the support bottom plate 1. The limit support frame 51 is arranged in an "n" shape, and a control motor 52 is provided on the outer wall of the top end of the limit support frame 51. The control motor 52 is connected to the outer wall of the top end of the reciprocating lead screw 53. The outer wall of the bottom end of the reciprocating lead screw 53 is connected to the outer wall of the top end of the auxiliary support shaft 54. The outer wall of the bottom end of the auxiliary support shaft 54 is rotatably installed on the outer wall of the top end of the support bottom plate 1. A limit block 55 is provided on the outer part of the reciprocating lead screw 53. Limit bumps are symmetrically arranged on both outer walls of the limit block 55, and the limit bumps are all slidably installed on the inner walls of the sides of the limit support frame 51. An auxiliary mounting plate 56 is provided on the outer wall of the side of the limit block 55. The outer wall of the side of the auxiliary mounting plate 56 is connected to the outer wall of the side of the sealing cover 3. When it is necessary to clean the solid impurities accumulated above the limit filter plate 41 after the solidification removal of the catalytic slurry stock solution, first, the control motor 52 needs to be started at this time. When the control motor 52 is started, it will automatically drive the reciprocating lead screw 53 to rotate and then drive the auxiliary support shaft 54 to rotate. Subsequently, when the reciprocating lead screw 53 rotates, it will automatically drive the limit block 55 to move. Here, due to the setting that the limit bumps arranged on both outer walls of the limit block 55 are slidably installed on the inner walls of the sides of the limit support frame 51, when the reciprocating lead screw 53 rotates, it will only drive the limit block 55 to move along a vertical reverse sliding track. Subsequently, when the limit block 55 moves, it will automatically drive the auxiliary mounting plate 56 to move. Furthermore, when the auxiliary mounting plate 56 moves, it will automatically drive the sealing cover 3 to move. When the sealing cover 3 is lifted to the highest position, the control motor 52 can be turned off at this time. It should be noted here that the control motor 52 has a self-locking function, and the sealing cover 3 can still maintain its position unchanged after moving. Furthermore, when the sealing cover 3 is lifted, a cavity structure is formed above the processing barrel 2. Subsequently, the solid impurities accumulated on the limit filter plate 41 can be directly cleaned.

[0026] A positioning snap ring 61 is provided on the outer wall of the bottom end of the sealing cover 3, and a positioning card slot 62 is opened on the outer wall of the top end of the processing barrel 2. The positioning snap ring 61 and the positioning card slot 62 are in a snap connection; the snap connection relationship between the positioning snap ring 61 and the positioning card slot 62 plays an auxiliary reinforcement effect on the tight installation of the processing barrel 2 and the sealing cover 3.

[0027] The auxiliary de-solidification mechanism includes a heat pipe 71, a heating wire 72 and a power supply 73. The heat pipe 71 is arranged on the outer side wall of the processing barrel 2. The heat pipe 71 is arranged in an annular structure, and the heating wire 72 is embedded and installed inside the heat pipe 71. The heating wire 72 is connected to the power supply 73. A controller 74 is arranged on the side of the power supply 73, and both the power supply 73 and the controller 74 are connected to the outer wall of the top of the support base plate 1. A protective cover 75 is arranged outside the power supply 73 and the controller 74. The protective cover 75 is connected to the outer wall of the top of the support base plate 1. A temperature monitoring sensor 76 is arranged on the outer wall of the top of the protective cover 75. A heat conduction rod 77 is connected between the temperature monitoring sensor 76 and the outer side wall of the heat pipe 71; Since the fluidity of catalytic slurry usually improves with the increase of temperature, generally speaking, the temperature between 60°C and 100°C can significantly improve the fluidity of catalytic slurry. Then, when it is necessary to heat the catalytic slurry to enhance its fluidity and facilitate the acceleration of the de-solidification process, first, the temperature monitoring sensor 76 needs to be adjusted to the appropriate monitoring range according to the safe heating range of the catalytic slurry. Then, the temperature monitoring sensor 76 is turned on. Here, the setting of the heat conduction rod 77 is to transmit the outer wall temperature of the heat pipe 71 to the temperature monitoring sensor 76 in real time. Once the outer wall temperature of the heat pipe 71 is lower than the monitoring range of the temperature monitoring sensor 76, at this time, the temperature monitoring sensor 76 will transmit the information to the controller 74 in real time. Then, the controller 74 will automatically control the power supply 73 to turn on. Then, when the power supply 73 is turned on, it will automatically supply power to the heating wire 72. Then, after the heating wire 72 is powered on and heated, it will heat the heat pipe 71 by heat transfer. At the same time, the heat pipe 71 will also synchronously heat the outer wall of the processing barrel 2 to heat the catalytic slurry stock solution to be de-solidified in the device. When the outer wall temperature of the heat pipe 71 is higher than the monitoring range of the temperature monitoring sensor 76, at this time, the temperature monitoring sensor 76 will also transmit the information to the controller 74. Then, the controller 74 will automatically control the power supply 73 to stop supplying power to the heating wire 72. In this way, the temperature control effect is achieved through the above working process. Then, as the catalytic slurry stock solution is heated, its fluidity will also be significantly improved, which is convenient for the subsequent acceleration of the de-solidification process.

[0028] When the present utility model is in use, as shown in the attached drawings of the specification Figure 1As shown, a feed hopper is conductively installed on the outer wall of the top end of the sealing cover 3. When solid removal treatment is required for the catalytic slurry stock solution, first, the catalytic slurry stock solution to be subjected to solid removal needs to be poured into the interior of the processing barrel 2 through the feed hopper. Since the fluidity of the catalytic slurry generally improves with the increase in temperature, generally speaking, the temperature between 60°C and 100°C can significantly improve the fluidity of the catalytic slurry. Thus, when it is necessary to heat the catalytic slurry to enhance its fluidity and facilitate the acceleration of the solid removal process, first, the temperature monitoring sensor 76 needs to be adjusted to the appropriate monitoring range according to the safe heating range of the catalytic slurry. Subsequently, the temperature monitoring sensor 76 is turned on. Here, the temperature guiding rod 77 is arranged to transmit the outer wall temperature of the temperature equalizing plate 71 to the temperature monitoring sensor 76 in real time. Once the outer wall temperature of the temperature equalizing plate 71 is lower than the monitoring range of the temperature monitoring sensor 76, the temperature monitoring sensor 76 will transmit the information to the controller 74 in real time. Subsequently, the controller 74 will automatically control the power supply component 73 to turn on. Then, when the power supply component 73 is turned on, it will automatically supply power to the heating wire 72. Subsequently, when the heating wire 72 is energized and heated, it will heat the temperature equalizing plate 71 through heat transfer. At the same time, the temperature equalizing plate 71 will also synchronously heat the outer wall of the processing barrel 2 to heat the catalytic slurry stock solution to be subjected to solid removal in the device. When the outer wall temperature of the temperature equalizing plate 71 is higher than the monitoring range of the temperature monitoring sensor 76, the temperature monitoring sensor 76 will also transmit the information to the controller 74. Then, the controller 74 will automatically control the power supply component 73 to stop supplying power to the heating wire 72. In this way, the temperature control effect is achieved through the above working process. Subsequently, as the catalytic slurry stock solution is heated, its fluidity will also be significantly improved, facilitating the acceleration of the subsequent solid removal process;

[0029] It should be noted here that the limiting filter plate 41 is set to a porous structure. Due to the setting of the limiting filter plate 41, when the catalytic slurry stock solution to be subjected to solid removal passes through the limiting filter plate 41, the internal solid impurities will be automatically isolated above the limiting filter plate 41. When it is necessary to accelerate the solid removal rate of the catalytic slurry stock solution, only the driving motor 43 needs to be turned on. After the driving motor 43 is turned on, it will automatically drive the transmission shaft 44 to rotate and then drive the limiting scraper 45 to rotate. Subsequently, when the limiting scraper 45 rotates, it will automatically push and rotate the solid impurities accumulated above the limiting filter plate 41. At the same time, by rotating horizontally, the rotation speed of the catalytic slurry stock solution is accelerated. Thus, the effect of accelerating solid removal is achieved on the basis of clearing the blockage of the limiting filter plate 41 and accelerating the rotation speed of the catalytic slurry stock solution. At the same time, through the above setting, when the limiting scraper 45 rotates, on the one hand, it can push and rotate the solid impurities accumulated above the limiting filter plate 41, thus avoiding the phenomenon that the impurities block the limiting filter plate 41 and cannot be filtered out. On the other hand, when the limiting scraper 45 rotates, it can also scrape off some of the catalytic slurry stock solution remaining on the inner wall of the processing barrel 2 to continue to participate in the solid removal treatment;

[0030] As shown in the instruction manual appendixFigure 1 As shown, a discharge pipe is conductively installed on the outer side wall of the processing barrel 2 at the bottom position, and a control valve is arranged outside the discharge pipe. When discharging, the control valve is directly opened, and then the solidified catalytic slurry stock solution will automatically flow out through the discharge pipe;

[0031] When it is necessary to clean the solid impurities accumulated above the limit filter plate 41 after the solidification of the catalytic slurry stock solution, first, the control motor 52 needs to be started. When the control motor 52 is started, it will automatically drive the reciprocating lead screw 53 to rotate, and then drive the auxiliary support shaft 54 to rotate. Subsequently, the rotation of the reciprocating lead screw 53 will automatically drive the limit block 55 to move. Here, due to the arrangement that the limit protrusions provided on the outer side walls of both sides of the limit block 55 are slidably installed on the inner side wall of the limit support frame 51, when the reciprocating lead screw 53 rotates, it will only drive the limit block 55 to move along a vertical reverse sliding track. Subsequently, the movement of the limit block 55 will automatically drive the auxiliary mounting plate 56 to move, and then the movement of the auxiliary mounting plate 56 will automatically drive the sealing cover 3 to move. When the sealing cover 3 is lifted to the highest position, the control motor 52 can be turned off at this time. It should be noted here that the control motor 52 has a self-locking function, and after it is turned off, the sealing cover 3 can still maintain its position unchanged after moving. Thus, when the sealing cover 3 is lifted, a cavity structure is formed above the processing barrel 2, and then the solid impurities accumulated on the limit filter plate 41 can be directly cleaned.

[0032] It should be noted here that the above driving motor 43 and control motor 52 can be powered according to the existing conventional operation technical means. Whether it is powered by a power supply component or an external wire, it belongs to the existing conventional operation technical means and will not be described in detail here.

[0033] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
