Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical equipment technology, specifically to a catalyst preparation device for high-temperature heavy oil viscosity reducers, which can prepare catalysts for high-temperature heavy oil viscosity reducers and filter harmful gases generated during the preparation process. Background Technology
[0002] In the process of heavy oil extraction, viscosity reducers need to be added to reduce the viscosity of the oil so that it can be easily pumped out of the well. Adding a catalyst during the reaction between the viscosity reducer and the heavy oil can effectively improve the viscosity reduction effect.
[0003] The catalysts used in downhole catalytic viscosity reduction for heavy oil extraction are transition metal sulfates, such as NiSO4, CoSO4, CuSO4, and VOSO4. NiSO4 is a weak acid or an acid with moderate strength. Its molecular formula below 31 degrees Celsius is NiSO4·6H2O. When heated to 150 degrees Celsius, it transforms into NiSO4·H2O. When heated to 300 degrees Celsius, less water is lost. However, if the temperature is increased further, the remaining water will be gradually lost. Generally, the acidity and catalytic activity are at their maximum around 300 degrees Celsius.
[0004] The preparation of catalysts for high-temperature heavy oil viscosity reducers sometimes needs to be carried out on-site. During the catalyst preparation process, heating metal sulfates may generate harmful gases such as sulfur dioxide and sulfur trioxide. If these harmful gases are directly emitted, they will not only harm the health of workers, but also pollute the atmosphere. Since the preparation is carried out outdoors, it is not easy to centrally treat the harmful gases. Absorbents (such as limestone and activated carbon) are used to adsorb the harmful gases. The adsorption capacity of the absorbent will gradually decrease with use. Traditional catalyst preparation equipment may have poor filtration efficiency because the absorbent cannot be replaced in time. Utility Model Content
[0005] This invention provides a catalyst preparation device for high-temperature heavy oil viscosity reducers. The device uses a spring-sensing slide plate within the filter assembly to detect the weight of the solid absorbent placed on it. When the absorbent has adsorbed harmful gases to a certain extent, it gradually loses its adsorption capacity and its weight increases, pressing the slide plate and support platform downwards. When the spring is compressed to a certain degree, the spring push rod pushes the rectangular frame, causing the slide plate to slide out of the housing, reminding the operator to replace the solid absorbent. This solves the problem of poor filtration efficiency of harmful gases generated during catalyst preparation in the prior art.
[0006] The technical solution of this utility model is as follows:
[0007] A catalyst preparation apparatus for high-temperature heavy oil viscosity reducers includes: a housing and a base. The housing is fixedly connected to the top of the base, and a housing cover is rotatably connected to the inner wall of the housing. A filter assembly is embedded in the housing. A tray is provided on the top of the base, and a tank is fixedly connected to the top of the tray. A pair of heating components are fixedly connected to the tank. An inlet and outlet are opened on the top of the tank. A pipe is fixedly connected to the top of the tank, and the pipe communicates with the internal space of the tank. A second motor is fixedly connected to the top of the pipe. The output end of the second motor passes through the pipe and is fixedly connected to a rotating shaft. Multiple stirring blades and multiple fans are fixedly connected to the rotating shaft. A vent pipe runs horizontally through one side of the pipe, and the other end of the vent pipe is connected to the internal space of the filter assembly. The filter assembly includes multiple springs, with a support platform fixedly connected to the top of each spring. A second groove is provided on the top of the support platform, and a sliding plate is mounted on top of the support platform. The sliding plate is slidably connected to the support platform. The filter assembly also includes a housing, with a chamber on one side. A spring push rod is fixedly connected to the inner wall of the chamber, and a rectangular frame is fixedly connected to the output end of the spring push rod. The support platform and the sliding plate are located within the rectangular frame, and the rectangular frame is slidably connected to the housing. An air inlet and an air exchange outlet are penetrating through the top of the housing. A first groove is provided on the top inner side of the housing, and a slider is mounted inside the first groove. The slider is slidably connected to the first groove, and a spring plate is fixedly connected to one side of the slider.
[0008] Preferably, a turntable is fixedly connected to the bottom of the tray, and a support column is provided at the bottom of the tray, with the support column rotatably connected to the turntable.
[0009] Preferably, a driven wheel is fixedly connected to the bottom of the support column, a plurality of electric telescopic rods are fixedly connected to the top of the driven wheel, a plurality of bearings corresponding to the electric telescopic rods are fixedly connected to the bottom of the tray, and the output end of the electric telescopic rod is rotatably connected to the bearing.
[0010] Preferably, a motor is fixedly connected to the bottom inner side of the base, and a gear is fixedly connected to the output end of the motor, the gear meshing with the driven wheel.
[0011] Preferably, a cylinder is fixedly connected to the bottom inner side of the base, and the cylinder is rotatably connected to the driven wheel.
[0012] Preferably, the vent pipe is made of a flexible material.
[0013] Preferably, a solid absorbent is placed on top of the skateboard.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This utility model utilizes the combined use of a support platform, spring, and sliding plate. The catalyst is prepared by heating in the tank. During the preparation process, harmful gases generated pass through a pipe, a vent pipe, and then through an inlet into the filter assembly. When the filter assembly is working normally, the spring lifts the support platform and sliding plate together. Part of the support platform and the sliding plate are located within the rectangular frame. Due to the limiting effect of the support platform, the spring push rod cannot push the rectangular frame out of the device. As the solid absorbent placed on the sliding plate continuously absorbs the harmful gases generated during the catalyst preparation process, its weight increases, pressing the sliding plate and support platform downwards. The spring is gradually compressed until the support platform is completely squeezed out of the rectangular frame. At this point, the spring push rod can push the rectangular frame and sliding plate out of the outer shell, making it convenient for operators to replace the solid absorbent and maintain the filtration capacity of the filter assembly.
[0016] 2. This utility model utilizes the combined use of a rectangular frame and a slider. When the rectangular frame is pushed out of the filter assembly, its inner wall adheres to the spring plate, causing the slider to slide within the first groove, blocking the air inlet. The slider cannot continue moving due to the restriction of the first groove. Under the action of the thrust, the spring plate is briefly squeezed and deformed, and the side wall of the rectangular frame slides past the spring plate to continue moving. When the solid absorbent is replaced and the rectangular frame is pushed back into the filter assembly, the outer wall of the rectangular frame will drive the spring plate and slider to move, opening the air inlet. After moving a certain distance, the slider will be restricted by the first groove. Under the action of the thrust, the rectangular frame will slide past the spring plate to continue moving until it is fully inside the filter assembly. The spring lifts the support platform, fixing the rectangular frame, thus preventing the leakage of harmful gases when replacing the solid absorbent and further enhancing the environmental protection function.
[0017] 3. This utility model utilizes the combined use of electric telescopic rods and driven wheels. When the device is operating outdoors and placed on a sloped surface, multiple electric telescopic rods on the driven wheels are activated, causing one side of the electric telescopic rod to shorten and the other side to extend. This causes the support column and tray to rotate, tilting the tank. Then, motor one is activated, and its output drives the gear to rotate, which in turn drives the driven wheel to rotate. The driven wheel then rotates the tank, adjusting the angle in conjunction with the electric telescopic rods to keep the tank level. This ensures uniform heating inside the tank during catalyst preparation, improving product quality. Attached Figure Description

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0029] This utility model provides a catalyst preparation device for high-temperature heavy oil viscosity reducers, comprising: a housing 2 and a base 1. The housing 2 is fixedly connected to the top of the base 1. A housing cover 201 is rotatably connected to the inner wall of the housing 2. A filter assembly 3 is embedded in the housing 2. A tray 101 is provided on the top of the base 1. A tank 202 is fixedly connected to the top of the tray 101. A pair of heating components 203 are fixedly connected to the tank 202. The heating components 203 provide the heat required during catalyst preparation. An inlet and outlet 204 are provided on the top of the tank 202 for the entry of raw materials before catalyst preparation and the removal of raw materials after catalyst preparation. A pipe 205 is fixedly connected to the top of the tank 202, and the pipe 205 is connected to the interior of the tank 202. The space is interconnected. A second motor 206 is fixedly connected to the top of the pipe 205. The output end of the second motor 206 passes through the pipe 205 and is fixedly connected to a rotating shaft 208. Multiple stirring blades 209 and multiple fans 210 are fixedly connected to the rotating shaft 208. The rotation of the stirring blades 209 makes the raw materials in the tank 202 heat more evenly. A vent pipe 207 is horizontally passed through one side of the pipe 205. The other end of the vent pipe 207 is connected to the internal space of the filter assembly 3. Harmful gases generated during the catalyst preparation process enter the filter assembly 3 through the pipe 205 and the vent pipe 207. The filter assembly 3 includes multiple springs 301. A support platform 302 is fixedly connected to the top of the multiple springs 301. A sliding groove is opened on the top of the support platform 302. 3021, the top of the support platform 302 is provided with a sliding plate 303, which is slidably connected to the support platform 302. The filter assembly 3 also includes a housing 311, with a chamber on one side of the housing 311. A spring push rod 310 is fixedly connected to the inner wall of the chamber. A rectangular frame 304 is fixedly connected to the output end of the spring push rod 310. The support platform 302 and the sliding plate 303 are located inside the rectangular frame 304. The rectangular frame 304 is slidably connected to the housing 311. An air inlet 306 and an air exchange port 305 pass through the top of the housing 311. A sliding groove 308 is provided on the top inner side of the housing 311. A slider 307 is provided inside the sliding groove 308. The slider 307 and the sliding groove 308 are connected. The sliding connection includes a spring plate 309 fixedly connected to one side of the slider 307. When the solid absorbent on the slide plate 303 adsorbs harmful components such as sulfur dioxide in the harmful gas, its weight increases, pressing the slide plate 303 and the support platform 302 downwards. The spring 301 is compressed, and the support platform 302 is squeezed out of the rectangular frame 304. The spring push rod 310 can then push the rectangular frame 304 and the slide plate 303 out of the filter assembly 3, making it easier for staff to replace the solid absorbent. During the process of the rectangular frame 304 being pushed out and back into the filter assembly 3, the spring plate 309 will drive the slider 307 to close and open the air inlet 306, so that harmful gas will no longer enter the filter assembly 3 during the replacement of the solid absorbent, reducing the leakage of harmful gas.
[0030] A turntable 104 is fixedly connected to the bottom of the tray 101, and a support column 103 is provided at the bottom of the tray 101. The support column 103 is rotatably connected to the turntable 104. When the turntable 104 and the support column 103 rotate, the tank 202 will tilt. When the device is installed on a sloping ground, the tank 202 inside the device can be kept horizontal.
[0031] The bottom of the support column 103 is fixedly connected to a driven wheel 109, and the top of the driven wheel 109 is fixedly connected to a plurality of electric telescopic rods 102. The bottom of the tray 101 is fixedly connected to a plurality of bearing seats 105 corresponding to the electric telescopic rods 102. The output end of the electric telescopic rod 102 is rotatably connected to the bearing seat 105. By extending and retracting the electric telescopic rod 102, the turntable 104 and the support column 103 can be driven to rotate, which facilitates the adjustment of the tilt angle of the tank 202.
[0032] A motor 107 is fixedly connected to the bottom inner side of the base 1. A gear 108 is fixedly connected to the output end of the motor 107. The gear 108 meshes with the driven wheel 109. When the motor 107 is started, its output end drives the gear 108 to rotate, which in turn drives the driven wheel 109 to rotate, causing the entire box 2 to rotate. With the help of the electric telescopic rod 102, the appropriate angle can be better adjusted. When the device is placed on a sloping ground, the tank 202 can be kept horizontal.
[0033] A cylinder 106 is fixedly connected to the bottom inner side of the base 1. The cylinder 106 is rotatably connected to the driven wheel 109. When the gear 108 rotates, it will drive the driven wheel 109 to rotate around the cylinder 106, thereby causing the housing 2 to rotate.
[0034] The vent pipe 207 is made of flexible material, and it still maintains its function of transmitting harmful gases when the tank 202 is tilted inside the box 2.
[0035] A solid absorbent is placed on top of the slide plate 303 to adsorb harmful substances in the gas generated during the catalyst preparation process.
[0036] Example 1: As Figure 1-8As shown, in this embodiment, the catalyst preparation device for high-temperature heavy oil viscosity reducer is placed on the ground. If the ground has a slope, multiple electric telescopic rods 102 on the driven wheel 109 are activated, shortening the electric telescopic rod 102 on the higher side and extending the electric telescopic rod 102 on the lower side, causing the turntable 104, which is rotatably connected to the support column 103, to deflect, thereby causing the tray 101 to rotate, rotating the tank 202 until it is parallel to the horizontal plane. If the tank 202 is not parallel to the horizontal plane at this time, the motor 107 is activated, and its output end drives the gear 108 to rotate, which drives the driven wheel 109 to rotate. The driven wheel 109 drives the box 2 to rotate, coordinating with the electric telescopic rods 102 to adjust the appropriate angle until the tank 202 is in a horizontal position. The box cover 201 is then opened, and the raw materials required for catalyst preparation are injected into the tank 202 through the inlet and outlet 204. Then the inlet and outlet 204 and the box cover 201 are closed. The preparation work is completed, and the preparation of the viscosity reducer catalyst can begin.
[0037] The heating component 203 is activated to heat the raw materials in the tank 202 to the temperature required for catalysis. During the heating process, the motor 206 is activated, and its output drives the rotating shaft 208 to rotate. The stirring blades 209 and the fan 210 on the rotating shaft 208 rotate together. The rotation of the stirring blades 209 can stir the raw materials in the tank 202, making them more evenly heated and improving the preparation rate. The rotation of the fan 210 causes the harmful gases generated during the preparation process to enter the pipe 205, and then enter the vent pipe 207 through the pipe 205. From the vent pipe 207, they enter the filter component 3 and react with the solid absorbent in the filter component 3. The harmful components such as sulfur dioxide in the harmful gases are adsorbed. The filtered gas is discharged into the box 2 through the vent 305. After the catalyst preparation is completed, the box cover 201 and the inlet and outlet 204 can be opened to put the catalyst into the heavy oil viscosity reduction work.
[0038] During the filtration of harmful gases by the filter assembly 3, the weight of the solid absorbent gradually increases due to continuous adsorption, and the pressure on the slide plate 303 and support platform 302 also gradually increases. The spring 301 at the bottom of the support platform 302 is gradually compressed, causing the height of the support platform 302 and the slide plate 303 to gradually decrease. When the solid absorbent still has adsorption capacity, part of the support platform 302 will be located inside the rectangular frame 304. At this time, due to the limitation of the support platform 302, the spring push rod 310 cannot push the rectangular frame 304. Figure 4 As shown, after the solid absorbent has been adsorbing for a long time, its weight gradually increases and its adsorption force gradually decreases. This will cause the support platform 302 to slide out of the rectangular frame 304. At this point, the adsorption capacity of the solid absorbent is insufficient, and the spring push rod 310 will push the rectangular frame 304 and the sliding plate 303 out of the outer shell 311. Figure 5As shown, this facilitates the replacement of the solid absorbent by the staff. After the replacement is completed, the rectangular frame 304 and the slider 307 are pushed back into the outer shell 311. The spring 301 will push the support platform 302 into the rectangular frame 304 to fix the rectangular frame 304, so that the filter assembly 3 can replace the solid absorbent in time and maintain the filtration capacity.
[0039] It should be noted that the weight difference of the solid absorbent is small each time it is replaced. When the spring push rod 310 pushes out the rectangular frame 304 and the slide plate 303, it does not push out the entire structure of the rectangular frame 304 and the slide plate 303 out of the filter assembly 3. The slide groove 3021 opened on the top of the support platform 302 cooperates with the slide plate 303 to limit the pushing distance.
[0040] During the process of pushing the rectangular frame 304 and the sliding plate 303 out of the filter assembly 3, the inner side of the side wall of the rectangular frame 304 will fit against the spring plate 309, pushing the spring plate 309 and the slider 307 to move along the slide groove 308, blocking the air inlet 306 and stopping harmful gases from entering the filter assembly 3. When the slider 307 moves to the edge of the slide groove 308, its position is restricted, and the thrust will squeeze the spring plate 309, causing it to deform briefly, allowing the side wall of the rectangular frame 304 to slide past the spring plate. 309 continues to move. When the rectangular frame 304 is pushed back into the filter assembly 3, the outer side of the side wall of the rectangular frame 304 will push the slider 307 to open the air inlet 306. When the slider 307 moves to its limit, the thrust will cause the rectangular frame 304 to slide past the spring plate 309 and continue to move until it enters the filter assembly 3. At this time, the vent pipe 207 is connected to the filter assembly 3 again and the filtration continues. Through the above steps, the leakage of harmful gases can be reduced while replacing the solid absorbent, thus improving the reliability of the device.

Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
