Description

Technical Field

[0001] The present invention relates to the technical field of polyacrylamide production and processing, and specifically to a polyacrylamide stirring device. Background Art

[0002] Polyacrylamide is a linear polymer. It is a hard glassy solid at room temperature. The products include glue solution, latex, white powder, translucent beads and flakes, etc. It has good thermal stability and can dissolve in water in any proportion. The aqueous solution is a uniformly transparent liquid. As a lubricant, suspending agent, clay stabilizer, oil displacement agent, fluid loss reducer and thickener, polyacrylamide has been widely used in drilling, acidizing, fracturing, water plugging, cementing, secondary oil recovery and tertiary oil recovery, and it is an extremely important oilfield chemical. In the production process of polyacrylamide, it is necessary to mix acrylamide monomers with initiators, solvents, etc. evenly to promote the polymerization reaction. The stirring device can make the reactants fully contact, improve the reaction rate and reaction efficiency. Herein, the present invention provides a polyacrylamide stirring device.

[0003] According to the search, the Chinese patent document, publication number: CN219404923U, discloses a polyacrylamide raw material adding and stirring device. By setting the connection relationship of the stirring barrel, feed pipe, feed inlet, holding barrel and feeding hole, it is possible to pour the polyacrylamide raw materials to be added into the holding barrel. By starting the driving motor, the holding barrel is driven to rotate, so that the feeding hole rotates. When the feeding hole moves above the feed inlet, the polyacrylamide raw materials pass through the feeding hole through the feed inlet and enter the feed pipe, and then fall into the stirring barrel. And by continuously rotating the holding barrel, the feeding hole moves above the feed inlet multiple times, which is convenient for intermittently feeding the stirring barrel, and is beneficial to preventing the phenomenon of excessive feeding at one time and avoiding affecting the dissolution effect. By starting the stirring shaft, it is convenient to stir and mix the raw materials added to the stirring barrel. However, in the actual use process of this device, the materials may precipitate at the bottom of the stirring barrel due to the action of gravity, resulting in incomplete reaction or uneven product quality; in addition, during the polymerization reaction process, a large amount of heat will be generated, and this device cannot transfer the heat out in time, so the reaction temperature cannot be controlled, and further local overheating or overcooling and other situations will occur. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a polyacrylamide stirring device, which has the advantages of preventing material precipitation, promoting heat transfer, improving reaction efficiency and ensuring product quality, and solves the above technical problems.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the present invention provides the following technical solution: a polyacrylamide stirring device, including a stirring barrel, a driving motor and a feed pipe are fixedly installed on the top surface of the stirring barrel, a partition is fixedly installed inside the stirring barrel, a driving shaft and a driven shaft are installed inside the partition, a spiral stirring blade is fixedly installed on the outer side surface of the driving shaft, a cooling pipe and a discharge pipe are fixedly installed on the outer side surface of the stirring barrel, one end of the cooling pipe close to the top of the stirring barrel is fixedly connected to a water pump, a connecting pipe is fixedly installed on the rear side surface of the water pump, and the rear end of the connecting pipe is fixedly connected to a radiator.

[0008] Preferably, the bottom end of the feed pipe is installed inside the partition, and a sealing cover is provided at the top of the feed pipe, and an electric valve is installed on the outer side surface of the discharge pipe.

[0009] Through the above technical solution, various raw materials can be injected into the stirring barrel through the feed pipe for stirring and mixing. The feed pipe can prevent materials from entering the position between the partitions, and the sealing cover can ensure that no impurities enter the stirring barrel during stirring. The electric valve can control the opening and closing state of the discharge pipe, improving the automation degree of the device and thus improving the overall working efficiency.

[0010] Preferably, the number of the driven shafts is two, and the number of the spiral stirring blades is three. The three spiral stirring blades are respectively installed on the outer side surfaces of the driving shaft and the two driven shafts.

[0011] Through the above technical solution, when the driving shaft, the two driven shafts and the three spiral stirring blades rotate simultaneously, the three spiral stirring blades can effectively stir and mix various raw materials, and the spiral stirring blades can also continuously lift the materials settled at the bottom, making the materials react completely, thereby improving the product quality.

[0012] Preferably, the output shaft of the driving motor is fixedly connected to the top end of the driving shaft, and a first driving pulley and a second driving pulley are fixedly installed on the outer side surface of the driving shaft.

The first driving pulley and the second driving pulley can drive the other two driven shafts to rotate together through parts such as a first belt. Therefore, only a single motor is needed to drive multiple spiral stirring blades to rotate together, saving unnecessary energy consumption and improving the overall transmission efficiency of the device.

[0014] Preferably, a first belt is drivingly connected to the outer sides of the first driving wheel and the first driven wheel, and a second belt is drivingly connected to the outer sides of the second driving wheel and the second driven wheel.

[0016] Preferably, one end of the cooling pipe close to the bottom of the stirring barrel is fixedly connected to the rear side of the radiator.

[0017] Through the above technical solution, when the water pump is started, the water pump can transport the coolant to the inside of the cooling pipe, and then can cool the stirring barrel and the materials inside it. After that, the heat-exchanged and heated coolant flows into the inside of the radiator, and the radiator can cool it down. Then the coolant flows back to the water pump to complete the cycle. Therefore, the device can be effectively cooled, thereby controlling the reaction temperature. Parts such as the radiator are all prior arts, so their working principles and the like will not be elaborated.

[0018] Preferably, a spiral groove is provided on the outer side of the stirring barrel, and the cooling pipe is installed inside the spiral groove.

[0019] Through the above technical solution, installing the cooling pipe inside the spiral groove can effectively increase its contact area with the stirring barrel, thereby improving its heat exchange effect, and also making the installation of the cooling pipe more stable, ensuring the normal operation of the device.

[0020] Compared with the prior art, the present invention provides a polyacrylamide stirring device, which has the following beneficial effects:

[0021] 1. By starting the driving motor of the present invention, the output shaft of the driving motor can drive the main shaft, the first driving wheel and the second driving wheel to rotate. The first driving wheel can drive the first driven wheel and one of the driven shafts to rotate through the first belt. Similarly, the first driven wheel can drive the second driven wheel and the other driven shaft to rotate through the second belt. Therefore, the three spiral stirring blades can effectively stir and mix various raw materials, and the spiral stirring blades can also continuously lift the materials settled at the bottom, making the materials react completely, thereby improving the product quality.

[0022] 2. In the present invention, by starting the water pump, the water pump can transport the coolant to the inside of the cooling pipe, thereby cooling the stirring barrel and the materials inside it. Then, the coolant that has been heated through heat exchange flows into the inside of the radiator, and the radiator can cool it down. After that, the coolant flows back to the water pump to complete the cycle. Therefore, the device can be effectively cooled, thereby controlling the reaction temperature. And by installing the cooling pipe inside the spiral groove, the contact area between it and the stirring barrel can be effectively increased, thereby improving the heat exchange effect and also making the installation of the cooling pipe more stable, ensuring the normal operation of the device.
