Description

Technical Field

[0001] The invention relates to the technical field of thickener preparation devices, and in particular to a thickener preparation device containing a beta-cyclodextrin gemini surfactant. Background Art

[0002] Thickener is a chemical substance that can increase the consistency or viscosity of a liquid. It forms a structural skeleton in the liquid, allowing the liquid to be adsorbed and fixed in these skeletons, thereby changing the physical state of the liquid from a liquid to a semi-solid state. Thickeners are widely used in many fields. In oil and natural gas extraction, thickeners are added to fracturing fluids to increase their consistency, thereby improving fracturing effects and recovery rates. Thickener components are also diverse. β-cyclodextrin (β-CD) gemini viscoelastic surfactant, as a new type of thickener, has low dosage, high viscosity and good temperature and shear resistance. The surfactant can still maintain a viscosity of about 150mPa·s after 60 minutes at 120℃ and 170s-1, meeting the viscosity requirements of clean fracturing fluids for on-site construction, and has excellent temperature and shear resistance, viscoelasticity and suspension support.

[0003] The Chinese invention patent with publication number CN117299063A: A raw material polymerization reaction device for producing fracturing fluid thickener, discloses a design of a mixing component that can drive the liquid to collide and mix between two mixing rollers, thereby increasing the uniformity of the mixing, and also solves the problem of stratification caused by different molecular weights of different raw materials during the stirring process; the use of a mixing component and a toggle plate for two mixings can improve the degree of polymerization of the raw materials; a technical solution that can automatically remove the filtered residue;

[0004] The Chinese utility model patent with publication number CN218553799U: A preparation device for producing an emulsion thickener for fracturing, which includes a preparation bin, a connecting frame is fixedly installed on both sides of the preparation bin, and the same driving structure is rotatably installed on the two connecting frames, and a support frame is fixedly installed on the inner wall of the preparation bin, and a stirring structure is rotatably installed on the support frame, which has the function of uniformly stirring the raw materials;

[0005] The above invention patent discloses a technical solution for filtering residues during the thickener production process, but the filtering effect is poor and cannot simultaneously meet high filtering efficiency and high filtering effect. In addition, the structure is complex, and the cost and energy consumption are high. It deviates from the existing industry's commonly used solution of using containers such as kettles as mixing chambers, and has low market acceptance. Summary of the invention

[0006] The object of the present invention is to provide a thickening agent preparation device containing β-cyclodextrin gemini surfactant to solve the technical problem in the prior art that residues cannot simultaneously meet high filtration efficiency and high filtration effect.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] The outer kettle comprises an inner filter cartridge installed therein, the inner filter cartridge comprises an inner filter cartridge body and an inner filter cartridge discharge pipe arranged at the bottom of the inner filter cartridge, the outer kettle comprises an outer kettle body, the inner filter cartridge is transmission-connected with a rotary drive mechanism, and the rotary drive mechanism can drive the inner filter cartridge to rotate, thereby improving the filtering effect;

[0009] A stirring tube is fixedly installed at one end of the outer wall of the filter hole close to the annular filter screen wall. The stirring tube rotates with the inner filter cylinder and can continue to stir and mix the filtered thickener and raw materials in the outer kettle to make the mixing more thorough.

[0010] In a top view, the free end of the stirring tube is inclined in a counterclockwise direction, so that when the mixed thickener or the raw material that is not completely mixed needs to be filtered into the outer kettle, the thickener in the outer kettle will not form resistance to the thickener or raw material flowing from the inner filter cartridge to the outer kettle, thereby ensuring the thickener filtering efficiency;

[0011] The inner filter cartridge body comprises an annular support wall and an annular filter screen wall which are vertically staggered and fixed. The annular filter screen wall is provided with filter holes. The annular filter screen wall can filter the thickener or raw material of the inner filter cartridge into the outer kettle and trap impurities in the inner filter cartridge. The annular support wall plays a role in maintaining the structural strength of the inner filter cartridge.

[0012] At least four guide plates are installed in a circular array on the inner wall of the inner filter cartridge. When the inner filter cartridge rotates, the guide plates play two roles. The first role is to stir and mix the raw materials in the inner filter cartridge, and the second role is to destroy the vortex phenomenon caused by the stirring. When the raw materials or thickeners near the side wall area of ​​the guide plates have a vortex tendency, they will be blocked by the guide plates, so that the raw materials or thickeners can be effectively assisted by centrifugal force and can be quickly filtered toward the outer kettle. The raw materials that are not thoroughly mixed after being filtered and enter the outer kettle will continue to be mixed in the outer kettle under the disturbance of the rotation of the inner filter cartridge until they are thoroughly mixed and discharged from the outer kettle discharge pipe.

[0013] By adopting the above technical scheme, the inner filter cartridge serves as a filtering container and a mixing container at the same time. The filtering container is the core technology of this scheme, and can efficiently filter the mixed thickener or incompletely mixed raw materials to the outer kettle, and retain impurities in the inner filter cartridge. With the assistance of centrifugal force, when the filter holes are small in diameter, the filtering operation can also be performed efficiently. The small-diameter filter holes can improve the filtering effect on impurities.

[0014] The outer kettle cover is provided with a feeding port, and the inner filter cartridge cover is provided with two symmetrically positioned feeding ports.

[0015] As a preferred solution, the rotating drive mechanism includes a support ring, a support rod, and a thrust bearing. A support ring is fixedly installed at the bottom end of the inner wall of the outer kettle, a support rod is fixedly installed on the inner wall of the support ring, and a thrust bearing is installed in the center of the support rod. The thrust bearing cooperates with the bearing of the inner filter cartridge discharge pipe to support the inner filter cartridge as a whole and enable the inner filter cartridge to rotate around the axis of the inner filter cartridge discharge pipe. A motor is fixed to the top support of the outer kettle, and the motor rotor is transmission-connected to the top of the inner filter cartridge, so that the motor can drive the inner filter cartridge to rotate.

[0016] As a preferred solution, the outer kettle also includes an outer kettle cover installed on the upper end of the outer kettle body by bolt connection, and an outer kettle bottom integrally formed with the bottom end of the outer kettle body. The outer kettle cover supports and fixes the motor, and the motor rotor passes downward through the outer kettle cover. The bottom end of the outer kettle bottom is connected and fixed with an outer kettle discharge pipe, and a valve is installed on the outer kettle discharge pipe.

[0017] As a preferred embodiment, the inner filter cartridge also includes an inner filter cartridge cover installed on the top of the inner filter cartridge body, and an inner filter cartridge bottom installed on the bottom of the inner filter cartridge body. The bottom end of the inner filter cartridge bottom is connected and fixed with an inner filter cartridge discharge pipe, and a valve is installed on the inner filter cartridge discharge pipe. After production is completed, the filtered impurities are discharged through the inner filter cartridge discharge pipe.

[0018] As a preferred solution, it also includes a transmission mechanism, which includes a snap-in connection block installed in the center of the top end of the inner filter cartridge cover, a snap-in groove is opened on the top surface of the snap-in connection block, and a snap-in block with the same shape as the snap-in groove is fixedly installed at the end of the motor rotor. The snap-in block is snapped into the inside of the snap-in groove. The use of the transmission mechanism is conducive to lifting the motor and the outer kettle cover, which is convenient for internal maintenance work of the separation and preparation device.

[0019] As a preferred embodiment, the lower half of the guide plate is a straight plate structure, and the upper half is an arc-shaped plate structure. When it is necessary to stir the inner filter cartridge mainly for mixing, the inner filter cartridge is driven to rotate counterclockwise in a top-down perspective, and the arc-shaped plate area can provide an upward driving force for the raw material, so that the raw material in the inner filter cartridge can obtain horizontal and vertical flow mixing effects at the same time, and the mixing efficiency is high; when it is necessary to filter the mixed thickener or the raw material that has not been thoroughly mixed into the outer kettle, the inner filter cartridge is driven to rotate clockwise in a top-down perspective, and the arc-shaped plate can hinder the upward flowing thickener or raw material, thereby enhancing the lateral flow force and improving the filtration efficiency.

[0020] As a preferred solution, the guide plate is inclined toward the concave surface of the arc plate on the side away from the annular support wall, which can reduce the stirring resistance when stirring mainly for mixing is required in the inner filter cartridge; when it is necessary to filter the mixed thickener or the raw materials that are not thoroughly mixed into the outer kettle, the retention resistance is increased, thereby further improving the thickener filtration efficiency.

[0021] As a preferred solution, a bearing is used to connect the middle part of the motor rotor and the outer kettle cover.

[0022] As a preferred solution, the inner filter cylinder body also includes a reinforced connecting plate for connecting and fixing adjacent annular support walls. The design of the reinforced connecting plate can increase the structural strength of the overall structure of the annular support wall and the reinforced connecting plate, thereby reducing the thickness requirement of the annular filter wall. On the premise of ensuring that the inner filter cylinder body can withstand the torsional force of the motor for a long time without deformation, the thickness of the annular filter wall is reduced to shorten the filter hole length. After production is completed, it is easy to clean out impurities blocked in the filter hole to avoid affecting production efficiency. In addition, the annular filter wall with a small thickness can reduce the overall mass of the inner filter cylinder and reduce motor power consumption.

[0023] Beneficial effects:

[0024] The present invention aims at the technical point of filtering the residue in the thickener production process, proposes an improved scheme, adopts the double space of the outer kettle and the inner filter cartridge to complete the preparation of the thickener, and can filter impurities and residues with high efficiency based on the filter cartridge principle. Compared with the existing technology, it has the advantages of small footprint, compact structure and low cost.

[0025] The guide plate designed in the present invention can improve the filtering effect by applying positive pressure, and at the same time can realize the auxiliary function of raw material stirring in the prior art.

[0026] The present invention makes a special design for the structure of the inner filter cylinder, which can ensure the overall strength of the structure while reducing the thickness of the annular filter wall, reducing the risk of clogging and improving the filtering efficiency;

[0027] The invention designs a stirring tube that is inclined in a counterclockwise direction, and can utilize the negative pressure generated by rotation during the production process to improve the filtering effect.

DETAILED DESCRIPTION

[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] Embodiment 1, as Figure 1-Figure 10As shown, a thickener preparation device containing β-cyclodextrin gemini surfactant includes an outer kettle, an inner filter cartridge is installed inside the outer kettle, the inner filter cartridge includes an inner filter cartridge body 200, and an inner filter cartridge discharge pipe 206 arranged at the bottom of the inner filter cartridge, the outer kettle includes an outer kettle body 101, and the inner filter cartridge is connected to a rotary drive mechanism, the rotary drive mechanism can drive the inner filter cartridge to rotate to improve the filtering effect, the rotary drive mechanism includes a support ring 401, a support rod 402, and a thrust bearing 403, and the inner wall of the outer kettle body 101 A support ring 401 is fixedly installed at the bottom end, a support rod 402 is fixedly installed on the inner wall of the support ring 401, a thrust bearing 403 is installed in the center of the support rod 402, and the thrust bearing 403 cooperates with the bearing of the inner filter cartridge discharge pipe 206 to support the inner filter cartridge as a whole, and enables the inner filter cartridge to rotate around the axis of the inner filter cartridge discharge pipe 206. A motor 301 is fixedly supported on the top end of the outer kettle, and the rotor of the motor 301 is transmission-connected with the top end of the inner filter cartridge, and the motor 301 can drive the inner filter cartridge to rotate;

[0045] The inner filter cartridge body 200 includes an annular support wall 201 and an annular filter screen wall 202 which are vertically staggered and fixed. The annular filter screen wall 202 is provided with filter holes 208. The annular filter screen wall 202 can filter the thickener or raw material of the inner filter cartridge into the outer kettle and trap impurities in the inner filter cartridge. The annular support wall 201 plays a role in maintaining the structural strength of the inner filter cartridge.

[0046] On the inner wall of the inner filter cartridge 200, six guide plates 207 are installed in a circular array. When the inner filter cartridge rotates, the guide plates 207 play two roles. The first role is to stir and mix the raw materials in the inner filter cartridge, and the second role is to destroy the vortex phenomenon caused by the stirring. When the raw materials or thickeners near the side wall area of ​​the guide plates 207 have a vortex tendency, they will be blocked by the guide plates 207, so that the raw materials or thickeners can be effectively assisted by centrifugal force and can be quickly filtered toward the outer kettle. The raw materials that are not thoroughly mixed after being filtered and enter the outer kettle will continue to be mixed in the outer kettle under the disturbance of the rotation of the inner filter cartridge until they are thoroughly mixed and discharged from the outer kettle discharge pipe 104.

[0047] By adopting the above technical solution, the inner filter cartridge serves as a mixing container and a filtering container at the same time, and can efficiently filter the mixed thickener or incompletely mixed raw materials to the outer kettle, and retain impurities in the inner filter cartridge. With the assistance of centrifugal force, when the filter hole 208 has a small aperture, the filtering operation can also be performed efficiently. The small aperture filter hole 208 can improve the filtering effect on impurities.

[0048] The outer kettle cover 102 is provided with a feeding port, and the inner filter cartridge cover 204 is provided with two symmetrically positioned feeding ports.

[0049] The outer kettle also includes an outer kettle cover 102 installed on the upper end of the outer kettle body 101 by bolt connection, and an outer kettle bottom 103 integrally formed with the bottom end of the outer kettle body 101. The outer kettle cover 102 supports and fixes the motor 301. The rotor of the motor 301 passes downward through the outer kettle cover 102. The bottom end of the outer kettle bottom 103 is connected and fixed with an outer kettle discharge pipe 104, and a valve is installed on the outer kettle discharge pipe 104.

[0050] The inner filter cartridge also includes an inner filter cartridge cover 204 installed on the top of the inner filter cartridge body 200, and an inner filter cartridge bottom 205 installed on the bottom of the inner filter cartridge body 200. The bottom end of the inner filter cartridge bottom 205 is connected and fixed with an inner filter cartridge discharge pipe 206, and a valve is installed on the inner filter cartridge discharge pipe 206. After production is completed, the filtered impurities are discharged through the inner filter cartridge discharge pipe 206.

[0051] It also includes a transmission mechanism, which includes a snap-in connection block 302 installed in the center of the top of the inner filter cartridge cover 204, a snap-in groove 303 is provided on the top surface of the snap-in connection block 302, and a snap-in block with the same shape as the snap-in groove 303 is fixedly installed at the end of the rotor of the motor 301, and the snap-in block is snapped into the inside of the snap-in groove 303. The use of the transmission mechanism is conducive to lifting the motor and the outer kettle cover 102, which is convenient for internal maintenance work of the separation and preparation device.

[0052] The lower part of the guide plate 207 is a straight plate structure, and the upper part is an arc-shaped plate structure. When it is necessary to stir the inner filter cartridge mainly for mixing, from a top-down perspective, the inner filter cartridge is driven to rotate counterclockwise, and the arc-shaped plate area can provide an upward driving force for the raw material, so that the raw material in the inner filter cartridge can obtain horizontal and vertical flow mixing effects at the same time, and the mixing efficiency is high; when it is necessary to filter the mixed thickener or the raw material that has not been thoroughly mixed into the outer kettle, from a top-down perspective, the inner filter cartridge is driven to rotate clockwise, and the arc-shaped plate can hinder the upward flowing thickener or raw material, thereby enhancing the lateral flow force and improving the filtration efficiency.

[0053] like Figure 7 As shown, the guide plate 207 is inclined toward the concave surface of the arc plate away from the annular support wall 201, which can reduce the stirring resistance when stirring mainly for mixing is required in the inner filter cartridge; when it is necessary to filter the mixed thickener or the raw materials that are not thoroughly mixed into the outer kettle, the retention resistance is increased, thereby further improving the thickener filtration efficiency.

[0054] The middle part of the rotor of the motor 301 is connected to the outer kettle cover 102 by a bearing.

[0055] The inner filter cartridge body 200 also includes a reinforced connecting plate 203 for connecting and fixing the adjacent annular support walls 201. The design of the reinforced connecting plate 203 can increase the structural strength of the overall structure of the annular support wall 201 and the reinforced connecting plate 203, thereby reducing the thickness requirement of the annular filter screen wall 202. On the premise that the inner filter cartridge body 200 can withstand the torsional force of the motor 301 for a long time without deformation, the thickness of the annular filter screen wall 202 is reduced to shorten the length of the filter hole 208. After production is completed, it is easy to clean out impurities blocked in the filter hole 208 to avoid affecting production efficiency. In addition, the annular filter screen wall 202 with a small thickness can reduce the overall mass of the inner filter cartridge and reduce the power consumption of the motor 301.

[0056] Example 2, based on the solution of Example 1, Figure 11-Figure 12 As shown, a stirring tube 209 is fixedly installed at one end of the outer wall of the filter hole 208 close to the annular filter wall 202. The stirring tube 209 rotates with the inner filter cylinder and can continue to stir and mix the thickener and raw materials after filtering in the outer kettle to make the mixing more thorough.

[0057] When viewed from above, the free end of the stirring tube 209 is tilted counterclockwise, so that when the mixed thickener or the raw material that has not been thoroughly mixed needs to be filtered into the outer kettle, the thickener in the outer kettle will not form resistance to the thickener or raw material flowing from the inner filter cartridge to the outer kettle, thereby ensuring the thickener filtration efficiency.

[0058] The stirring tube tilted in the counterclockwise direction can perform efficient cleaning after production is completed to fill the inner filter cartridge and the outer kettle with cleaning liquid. The stirring tube is indirectly driven by a motor and rotates counterclockwise in a top-down perspective, so that the cleaning liquid can be continuously poured into the stirring tube from the outer kettle. The cleaning liquid flows toward the inner filter cartridge to backwash the residue blocking the surface of the filter hole, making the present invention easy to maintain.

[0059] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
