Description

Technical Field

[0001] This invention relates to the field of liquid refining technology, specifically to a solid-liquid continuous adsorption refining apparatus and process. Background Technology

[0002] Currently, liquid refining activities exist in many fields, aiming to reduce the content of non-ideal components in liquids, improve liquid quality, and enhance their performance. Traditional adsorption extraction processes include two types: column adsorption and contact stirring adsorption. Each method has its advantages and disadvantages. Column adsorption is a semi-continuous adsorption method, where the adsorbent is stored within the column, and the liquid continuously flows through the adsorbent for adsorption. This method gradually saturates the adsorbent, resulting in good refining effects, but requires periodic adsorbent replacement, leading to low production efficiency. Contact stirring adsorption is a gap-type adsorption method, providing uniform adsorption and high production efficiency, but the refining effect is generally average, and post-processing is more complicated.

[0003] In this regard, Chinese Patent No. CN109758788B discloses a solid-liquid continuous adsorption purification device and process. The device includes a cylinder, and an adsorbent interception mesh plate is arranged horizontally inside the cylinder. The adsorbent interception mesh plate divides the inside of the cylinder into a first section and a second section. Several baffles are arranged at intervals in the second section. The cylinder wall is also provided with an adsorbent inlet, an adsorbent outlet, a liquid inlet, a liquid outlet and a vent.

[0004] This device employs continuous adsorption, eliminating the need for adsorbent replacement and resulting in high production efficiency. However, the adsorbent is forced in from the upper inlet and then contacts the liquid in a counter-current manner from top to bottom, remaining at the bottom of the second section. This process is relatively slow. Although a stirring structure is incorporated, situations still arise where the adsorbent trapped inside cannot come into contact with the liquid, leading to low adsorbent utilization. Furthermore, the adsorbent generates flow force solely through centrifugal or centripetal thrust, which, due to their opposite directions, results in poor flow stability. Therefore, we propose a solid-liquid continuous adsorption purification device and process to address these issues. Summary of the Invention

[0005] The purpose of this invention is to provide a solid-liquid continuous adsorption purification apparatus and process to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a solid-liquid continuous adsorption purification device, comprising a solenoid, one end of which is fixedly connected to an inlet pipe, and the other end of which is fixedly connected to an outlet pipe. A plurality of connecting rods are fixedly connected to one end of each connecting rod, and a support column is fixedly connected to the other end of each support column.

An adsorbent discharge section is fixedly connected to the bottom of the adsorbent discharge section, and the support column is fixedly connected to the bottom of the support column. The adsorbent filling tubes are evenly distributed circumferentially. The adsorbent filling tubes are fixedly connected to the solenoid and are interconnected. The axis of the adsorbent filling tubes is parallel to the spiral centerline of the solenoid. A drive assembly is movably mounted on the top of the adsorbent injection section.

[0007] Preferably, valves are fixedly installed at both ends of the solenoid, with the inlet pipe located at the bottom and the outlet pipe located at the top.

[0009] Preferably, the inner diameter of the solenoid is smaller than the inner diameter of the adsorbent filling tube, the adsorbent filling tube is vertically arranged, and the axis of the adsorbent filling tube coincides with the helix of the solenoid.

[0010] Preferably, the inner wall of the adsorbent filling tube is fixedly connected with several meshes, and each mesh is fixedly connected to the opening where the solenoid and the adsorbent filling tube connect.

[0011] Preferably, one end of the adsorbent injection section is coaxially fixed with a feeding pipe, and the inner wall of the other end of the adsorbent injection section is fixedly connected with a frustum block.

[0012] Preferably, the drive assembly includes a double-sided gear ring, a driven gear, a stirring shaft, a driving gear, and a servo motor. Several stirring shafts are provided, each with its top rotatably connected to an adsorbent injection unit. The bottom of each stirring shaft is coaxially rotatably installed inside an adsorbent filling tube. The top of each stirring shaft is fixedly sleeved with a driven gear. Each driven gear meshes with the inner side of the double-sided gear ring, and the outer side of the double-sided gear ring meshes with a driving gear. The driving gear is fixedly connected to a servo motor, and the servo motor is fixedly connected to the adsorbent injection unit.

[0013] Preferably, a plurality of transverse stirring rods are fixedly connected to the periphery of the stirring shaft, and the transverse stirring rods are all rotatably disposed inside the adsorbent filling tube. A plurality of cutting rods are fixedly connected to the periphery of the transverse stirring rods, and the axes of the cutting rods are perpendicular to the axes of the transverse stirring rods and parallel to the axes of the stirring shaft.

[0014] A process for a solid-liquid continuous adsorption purification apparatus is also provided, comprising the following steps:

[0015] S1. The feed pipe is connected to the adsorbent supply box. The pump body draws the adsorbent into the adsorbent injection section, and then from the adsorbent injection section into the adsorbent filling pipe.

The separated liquid is temporarily stored in the storage tank and finally transported by the lift pump to the solenoid for further purification.

[0019] S5. While the saturated adsorbent is being discharged from the adsorbent-filled tube, new adsorbent is being filled into the tube.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the liquid flows upward in a spiral through the solenoid, and during the flow, it comes into contact with the adsorbent inside the adsorbent filling tube, resulting in more thorough contact between them. At the same time, the driving component agitates the adsorbent inside the adsorbent filling tube to prevent accumulation, ensuring complete contact between the liquid and the adsorbent. When replacing the adsorbent, the liquid flows from bottom to top in a spiral structure, and the adsorbent is discharged from top to bottom, enabling continuous production without affecting the adsorption process.

[0027] Example 1

[0028] Reference Figure 1 , 2 This is the first embodiment of the present invention, which provides a solid-liquid continuous adsorption purification device, including a solenoid 2. One end of the solenoid 2 is fixedly connected to an inlet pipe 1, and the other end of the solenoid 2 is fixedly connected to an outlet pipe 4. One end of several connecting rods 16 is fixedly connected to the inner side of the solenoid 2, and the other end of the connecting rods 16 is fixedly connected to a support column 15. The top end of the support column 15 is fixedly connected to an adsorbent injection section 6, and the bottom end of the adsorbent injection section 6 is fixedly connected to several adsorbent filling tubes 3. The bottom end of the adsorbent filling tubes 3 is fixedly connected to an adsorbent discharge section 9, and the adsorbent discharge section 9 is fixedly connected to the bottom end of the support column 15. The adsorbent filling tubes 3 are evenly distributed around the circumference, and the adsorbent filling tubes 3 are fixedly connected to the solenoid 2 and are interconnected. The axis of the adsorbent filling tubes 3 is parallel to the spiral center line of the solenoid 2. A drive assembly 7 is movably installed on the top of the adsorbent injection section 6.

[0029] A process for a solid-liquid continuous adsorption purification apparatus is also provided, comprising the following steps:

[0030] S1. The feed pipe 8 is connected to the adsorbent supply box. The pump body draws the adsorbent into the adsorbent injection section 6, and then from the adsorbent injection section 6 into the adsorbent filling pipe 3.

[0031] S2. Open valve 5 and introduce liquid from the bottom inlet pipe 1 into the solenoid 2. The liquid flows along the solenoid 2 and then passes through the adsorbent filling pipe 3. The adsorbent inside the adsorbent filling pipe 3 comes into contact with the liquid.

[0032] S3, drive component 7 works to agitate the adsorbent inside adsorbent filling tube 3, increasing the contact area between the liquid and the adsorbent;

[0033] S4. The refined liquid is discharged and collected from the outlet pipe 4. After the adsorbent inside the adsorbent filling pipe 3 is saturated, the slurry pump 10 works to extract the saturated adsorbent into the centrifugal separator 11 for separation. The separated liquid is temporarily stored in the storage tank 12 and finally transported by the lift pump 13 to the solenoid 2 for further purification of the separated liquid.

[0034] S5. While the saturated adsorbent is discharged from the adsorbent filling tube 3, new adsorbent is also filled into the adsorbent filling tube 3, which can realize continuous purification.

[0035] Example 2

[0036] Reference Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, valves 5 are fixedly installed at both ends of the solenoid 2. The valves 5 are set to control the flow of liquid. The inlet pipe 1 is located at the bottom and the outlet pipe 4 is located at the top, so that the liquid can flow in a spiral form from bottom to top.

[0037] Specifically, the bottom end of the adsorbent discharge section 9 is fixedly connected to the slurry pump 10 through a pipeline, the slurry pump 10 is fixedly connected to the centrifuge 11 through a pipeline, the centrifuge 11 is fixedly connected to the storage tank 12 through a pipeline, the top of the storage tank 12 is fixedly installed with a lift pump 13, the lift pump 13 is fixedly connected to one end of the return pipe 14, and the other end of the return pipe 14 is fixedly connected to the inlet pipe 1.

[0038] After the adsorbent inside the adsorbent filling tube 3 is saturated, the slurry pump 10 operates to extract the saturated adsorbent into the centrifugal separator 11 for separation. The separated liquid is temporarily stored in the storage tank 12 and finally transported by the lift pump 13 to the solenoid 2 for further purification by the spiral flow from bottom to top.

[0039] Specifically, the inner diameter of the solenoid 2 is smaller than the inner diameter of the adsorbent filling tube 3. The adsorbent filling tube 3 is set vertically, and its axis coincides with the helix of the solenoid 2, so that the adsorbent filling tube 3 and the solenoid 2 can communicate with each other.

[0040] Specifically, the inner wall of the adsorbent filling tube 3 is fixedly connected with several partitions 21. The partitions 21 are all fixedly connected to the openings where the solenoid 2 and the adsorbent filling tube 3 are connected. The partitions 21 allow the liquid to pass smoothly through the adsorbent filling tube 3, while the adsorbent inside the adsorbent filling tube 3 will not enter the solenoid 2.

[0041] Specifically, one end of the adsorbent injection section 6 is coaxially fixed with the feeding pipe 8, and the inner wall of the other end of the adsorbent injection section 6 is fixedly connected with the frustum block 61. The feeding pipe 8 is connected to the adsorbent supply box. The pump body draws the adsorbent through the feeding pipe 8 into the adsorbent injection section 6. The frustum block 61 is narrow at the top and wide at the bottom, which facilitates the adsorbent to slide smoothly into the adsorbent filling tube 3 and avoids adsorbent accumulation.

[0042] Specifically, the drive assembly 7 includes a double-sided gear ring 71, a driven gear 72, a stirring shaft 73, a driving gear 74, and a servo motor 75. Several stirring shafts 73 are provided, and their tops are all rotatably connected to the adsorbent injection section 6. The bottoms of the stirring shafts 73 are all coaxially rotatably installed inside the adsorbent filling tube 3. The top of the stirring shaft 73 is fixedly sleeved with the driven gear 72. The driven gears 72 are all meshed with the inner side of the double-sided gear ring 71, and the outer side of the double-sided gear ring 71 is meshed with the driving gear 74. The driving gear 74 is fixedly connected to the servo motor 75, and the servo motor 75 is fixedly connected to the adsorbent injection section 6.

[0043] Furthermore, several transverse stirring rods 731 are fixedly connected to the periphery of the stirring shaft 73. The transverse stirring rods 731 are all rotatably disposed inside the adsorbent filling tube 3. Several cutting rods 732 are fixedly connected to the periphery of the transverse stirring rods 731. The axis of the cutting rods 732 is perpendicular to the axis of the transverse stirring rods 731, and the axis of the cutting rods 732 is parallel to the axis of the stirring shaft 73.

[0044] When the drive component 7 is working, the servo motor 75 is powered on and drives the fixed drive gear 74 to rotate. The drive gear 74 drives the meshing double-sided gear ring 71 to rotate. The double-sided gear ring 71 is connected to the top of the adsorbent injection section 6. When the double-sided gear ring 71 rotates, it drives the multiple driven gears 72 meshing on the inner side to rotate synchronously. The driven gears 72 drive the fixed stirring shaft 73 to rotate circumferentially. The stirring shaft 73 stirs the adsorbent inside the adsorbent filling tube 3 to prevent the adsorbent from clumping and to increase the contact area between the liquid and the adsorbent.

[0045] Example 3

[0046] Reference Figure 1-4This is the third embodiment of the present invention, based on the above two embodiments. In use, the feeding pipe 8 is connected to the adsorbent supply box. The pump body draws adsorbent into the adsorbent injection section 6, and then from the adsorbent injection section 6 into the adsorbent filling tube 3. The frustum block 61 fixed to the adsorbent injection section 6 is narrow at the top and wide at the bottom, facilitating the smooth sliding of the adsorbent into the adsorbent filling tube 3 and preventing adsorbent accumulation. The valve 5 is opened, and liquid is introduced from the bottom inlet pipe 1 into the solenoid 2. The liquid flows along the solenoid 2, passes through the partition mesh 21, and enters the adsorbent filling tube 3 to contact the adsorbent. The liquid flows in a spiral pattern within the solenoid 2, then passes through multiple adsorbent filling tubes 3, contacting the adsorbent in each tube 3 sequentially from bottom to top, improving adsorption efficiency. The drive component 7 operates, and the servo motor 75 is energized, driving the fixed drive gear 74 to rotate. The drive gear 74 drives the meshing... The double-sided toothed ring 71 rotates, connecting to the top of the adsorbent injection section 6. When the double-sided toothed ring 71 rotates, it drives multiple driven gears 72 meshing on their inner sides to rotate synchronously. The driven gears 72 drive the fixed stirring shaft 73 to rotate circumferentially. The stirring shaft 73 agitates the adsorbent inside the adsorbent filling tube 3, increasing the contact area between the liquid and the adsorbent and preventing adsorbent agglomeration. The refined liquid is discharged and collected from the outlet pipe 4. After the adsorbent inside the adsorbent filling tube 3 becomes saturated, the slurry pump 10 operates, extracting the saturated adsorbent into the centrifuge 11 for separation. The separated liquid is temporarily stored in the storage tank 12 and finally transported by the lift pump 13 to the solenoid 2 for further purification. While the saturated adsorbent is discharged from the adsorbent filling tube 3, new adsorbent is also added inside. The direction of adsorbent addition is consistent to avoid affecting the agitation of the liquid flow and the stability of the adsorbent supply.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
