Description
A polymerization reactor for drilling fluid production Technical Field
[0001] This utility model relates to the field of drilling fluid production technology, and in particular to a polymerization reactor for drilling fluid production. Background Technology
[0002] The polymerization reactor is one of the key pieces of equipment used in the drilling fluid production process to synthesize or polymerize chemical substances, especially in the preparation of drilling fluids containing polymers. Polymers are widely used in drilling fluids, usually to enhance the properties of drilling fluids, such as viscosity, rheology, and mud stability.
[0003] In existing drilling fluid production polymerization reactors, the preparation of drilling fluid often lacks a dedicated defoaming structure. This leads to the easy generation of a large amount of foam in the system due to the chemical properties of the raw materials and the intense stirring during the reaction. The formation of this foam first occupies a large amount of space in the polymerization reactor, reducing the effective reaction volume, limiting the amount of material added, and reducing production efficiency. The presence of the foam layer also seriously affects the stirring effect, causing uneven mixing of materials, hindering heat transfer, and resulting in uneven reaction temperature distribution, which affects the polymerization process. At the same time, if foam remains in the final drilling fluid product, it will change the key performance indicators such as rheology and density of the drilling fluid, affecting its actual use in drilling operations. Summary of the Invention

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Example 1, please refer to Figures 1 to 7. This utility model provides a technical solution: a polymerization reactor for drilling fluid production, including a polymerization reactor body 1, a support base 101 fixedly installed on the top of the polymerization reactor body 1, a motor 102 disposed inside the support base 101, an eccentric wheel 104 fixedly sleeved on the outer surface of the output shaft of the motor 102, and further including: a push plate 103, slidably connected to the top of the polymerization reactor body 1, two first return springs 105 fixedly installed on the right side of the push plate 103, the other ends of the two first return springs 105 being fixed to the top of the polymerization reactor body 1; an air cylinder 107, fixedly installed on the top of the polymerization reactor body 1, a movable plate 108 slidably connected inside the air cylinder 107, a push rod 106 fixedly installed on the left side of the movable plate 108, and the push rod 106... The left side of 06 is fixedly installed on the right side of the push plate 103. The right side of the air cylinder 107 is provided with a first air pipe 109. The two sides of the inside of the first air pipe 109 are fixedly installed with second air pipes 110. The other ends of the two second air pipes 110 are fixedly installed with first support columns 111. The two first support columns 111 are fixedly installed inside the polymerization reactor body 1. The inside of the two first support columns 111 is slidably connected with second support columns 112. The top of the two second support columns 112 is fixedly installed with second return springs 113. The other ends of the two second return springs 113 are fixedly installed on the top side of the inner wall of the first support column 111. The bottom of the two second support columns 112 is fixedly installed with defoaming plates 114. The defoaming plates 114 are slidably connected inside the polymerization reactor body 1.
[0035] In this embodiment, personnel can first feed raw materials into the interior of the polymerization reactor body 1 through the liquid inlet pipe 115, and then start the motor 102 through the power supply system of the motor 102 on the support base 101. When running, the motor 102 can drive the first rotating rod 2 through the output shaft, and the first rotating rod 2 drives the stirring blade 211 and the scraper 212 to rotate in a circle to stir the raw materials. At the same time, the scraper 212 scrapes off the raw materials adhering to the inner wall of the polymerization reactor body 1 to prevent incomplete mixing. When the output shaft of the motor 102 rotates, it will synchronously drive the eccentric wheel 104 to rotate in a circle. When the eccentric wheel 104 rotates to the right, it will push the push plate 103 to slide to the right on the top of the polymerization reactor body 1 and squeeze the first return spring 105 to retract. When the push plate 103 slides, it will squeeze the movable plate 108 inside the air cylinder 107 through the push rod 106, so that it can slide to the right inside the air cylinder 107. The air pump moves and simultaneously pushes the air inside the air cylinder 107, causing it to enter the first support column 111 through the first air pipe 109 and the second air pipe 110. When the air enters the first support column 111, it will squeeze the second support column 112 through air pressure, allowing it to slide downward inside the first support column 111. At the same time, it pulls the second return spring 113, causing it to extend. The second support column 112 drives the defoaming plate 114 to descend, thereby pressing down on the foam on the top of the raw material and eliminating it. After the drilling fluid is processed, the personnel can open the one-way valve 117, allowing it to flow out of the polymerization reactor body 1 through the liquid outlet pipe 116. The structure of the defoaming plate 114 and the eccentric wheel 104 can drive the defoaming plate 114 to descend, directly acting on the foam layer on the surface of the raw material to effectively remove the foam and prevent the foam from affecting the reaction process or product quality.
[0036] Example 2, as shown in Figures 1 to 7, has an inlet pipe 115 fixedly installed on the right side of the inside of the polymerization reactor body 1, and an outlet pipe 116 fixedly installed at the bottom of the polymerization reactor body 1. A one-way valve 117 is installed inside the outlet pipe 116. A first rotating rod 2 is movably embedded on the top side of the inside of the polymerization reactor body 1. The top of the first rotating rod 2 is fixedly installed at the bottom of the output shaft of the motor 102. The first rotating rod 2 is movably embedded inside the defoaming plate 114. A first bevel gear 201 is fixedly sleeved on the outer surface of the first rotating rod 2. A second rotating rod 202 is movably embedded on the left side of the inside of the polymerization reactor body 1. A second bevel gear 203 is fixedly installed on the right side of the second rotating rod 202. The second bevel gear 203 meshes with the adjacent first bevel gear 201. A material conveying component 204 is movably sleeved on the outer surface of the second rotating rod 202. The conveying component 204 is fixed to the left side of the polymerization reactor body 1. A material distribution plate 205 is fixedly sleeved on the outer surface of the second rotating rod 202 and inside the conveying component 204. The material distribution plate 205 has multiple slots 206 inside. A first feed pipe 207 is fixedly installed on the top of the conveying component 204. A storage box 208 is fixedly installed on the top of the first feed pipe 207. A second feed pipe 209 is fixedly installed on the top of the storage box 208. A discharge pipe 210 is fixedly installed on the bottom of the material distribution plate 205. The other end of the discharge pipe 210 is fixed to the left side inside the polymerization reactor body 1. Multiple stirring blades 211 are fixedly installed on both sides of the outer surface of the first rotating rod 2. Scrapers 212 are fixedly installed on both sides of the first rotating rod 2. The outer surfaces of the two scrapers 212 are movably connected to the inner wall of the polymerization reactor body 1.
[0037] In this embodiment, personnel can first add defoaming agent into the storage tank 208 through the second feed pipe 209. When the first rotating rod 2 rotates, it will drive the second bevel gear 203 through the first bevel gear 201. The second bevel gear 203 will then drive the material distribution disc 205 inside the conveying component 204 to rotate through the second rotating rod 202. When the material distribution disc 205 rotates, it can drive the slot 206 to rotate in a circle. When one of the slots 206 rotates to the bottom of the first feed pipe 207, the defoaming agent inside the storage tank 208 will be defoamed. The defoamer falls into the slot 206 through the first feed pipe 207. When one of the slots 206 rotates to the top of the discharge pipe 210, the defoamer inside the slot 206 can flow into the polymerization reactor body 1 through the discharge pipe 210. Through the structure of the storage box 208 and the distribution plate 205, the slot 206 can automatically receive the defoamer and transport it to the discharge pipe 210, reducing the need for manual addition of defoamer, avoiding errors and uneven distribution caused by human operation, making the whole process more automated, and improving the continuity and stability of production.
[0038] Working principle: During use, personnel can first feed raw materials into the polymerization reactor body 1 through the liquid inlet pipe 115, and then start the motor 102 through the power supply system of the motor 102 on the support base 101. When running, the motor 102 can drive the first rotating rod 2 through the output shaft, and the first rotating rod 2 drives the stirring blade 211 and scraper 212 to rotate in a circle to stir the raw materials. At the same time, the scraper 212 scrapes off the raw materials adhering to the inner wall of the polymerization reactor body 1 to prevent incomplete mixing. When the output shaft of the motor 102 rotates, it will synchronously drive the eccentric wheel 104 to rotate in a circle. When the eccentric wheel 104 rotates to the right, it will push the push plate 103 to slide to the right on the top of the polymerization reactor body 1 and squeeze the first return spring 105 to retract. When the push plate 103 slides, it will squeeze the movable plate 108 inside the air cylinder 107 through the push rod 106, so that it can move to the right inside the air cylinder 107. The air cylinder 107 slides sideways and simultaneously pushes the air inside the cylinder 107, allowing it to enter the first support column 111 through the first air pipe 109 and the second air pipe 110. Once the air enters the first support column 111, it will compress the second support column 112 through air pressure, causing it to slide downward inside the first support column 111. At the same time, it pulls the second return spring 113, causing it to extend. The second support column 112 then drives the defoaming plate 114 to descend, thereby pressing down on the foam on top of the raw material and eliminating it. After the drilling fluid processing is completed, the operator can open the one-way valve 117, allowing it to flow out of the polymerization reactor body 1 through the outlet pipe 116. The structure of the defoaming plate 114 and the eccentric wheel 104 allows the defoaming plate 114 to descend, directly acting on the foam layer on the surface of the raw material to effectively remove the foam and prevent it from affecting the reaction process or product quality. In use, personnel can first add defoaming agent into the storage bin 208 through the second feed pipe 209. When the first rotating rod 2 rotates, it will drive the second bevel gear 203 through the first bevel gear 201. The second bevel gear 203 then drives the material distribution disc 205 inside the conveying component 204 to rotate through the second rotating rod 202. When the material distribution disc 205 rotates, it can drive the slot 206 to rotate in a circle. When one of the slots 206 rotates to the bottom of the first feed pipe 207, the defoaming agent inside the storage bin 208 will be defoamed. The defoamer falls into the slot 206 through the first feed pipe 207. When one of the slots 206 rotates to the top of the discharge pipe 210, the defoamer inside the slot 206 can flow into the polymerization reactor body 1 through the discharge pipe 210. Through the structure of the storage box 208 and the distribution plate 205, the slot 206 can automatically receive the defoamer and transport it to the discharge pipe 210, reducing the need for manual addition of defoamer, avoiding errors and uneven distribution caused by human operation, making the whole process more automated, and improving the continuity and stability of production.
