[0002] In the process of preparing the filtration reducer, a stirring equipment is required to mix the dispersant and petroleum products. In order to facilitate the disassembly and cleaning of the stirring rod and the stirring blades in the stirring equipment, the existing solution, such as patent application No. 202220323938.7, discloses a filtration reducer preparation device, including a mixing box, a motor, a rotating rod and a limiting mechanism, etc. By utilizing the mutual cooperation of the rotating rod, the stirring rod, the fixed rod, the limiting block, the fixed frame, the spring, the connecting rod and the fixed plate, the elastic force of the spring causes the limiting block to return to its original position after movement, and the limiting block installs and disassembles the fixed rod, which is conducive to the disassembly of the stirring rod and facilitates the cleaning of the stirring rod and the stirring blades.

[0003] However, the above disclosed technical solution has the following defects in actual operation: first, before the stirring rod is disassembled, when the sealing plate is lifted upward, the stirring rod, stirring blades, motor and other structures will increase the weight when lifting, resulting in a large amount of manpower consumed in lifting the sealing plate; secondly, when disassembling the stirring rod, two connecting rods need to be pulled. Due to the existence of the spring, it is impossible to pull one connecting rod with one hand and then pull the other, resulting in the need for both hands to complete the operation of the two connecting rods, causing inconvenience in disassembling the stirring rod. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a stirring device for preparing filtration loss reducer. On the basis of the existing technical structure, an electric push rod is added to drive the sealing plate to move upward, and there is no need to lift the sealing plate manually, thereby avoiding the phenomenon that manually lifting the sealing plate consumes a lot of manpower. By adding a handle, a torsion spring, a connecting block and a top plate, the two connecting rods can be moved at the same time by rotating the handle. When disassembling the stirring rod, it is convenient for the staff to complete the operation with one hand, making the disassembly of the stirring rod more convenient.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A stirring device for preparing a filtration loss reducer comprises a mixing box, wherein a stirring rod is arranged inside the mixing box, and a plurality of stirring blades are fixedly connected to both sides of the stirring rod, a sealing plate is arranged above the mixing box, a motor is fixedly connected to the top of the sealing plate, a rotating rod is fixedly connected to the output shaft of the motor, a limiting mechanism is arranged between the rotating rod and the stirring rod, the limiting mechanism comprises a fixing rod and two limiting blocks, the bottom end of the fixing rod is fixedly connected to the stirring rod, the fixing rod is located on the rotating rod, the two limiting blocks are respectively located on both sides of the fixing rod, a mounting groove is provided at the bottom of the rotating rod, the fixing rod is slidably and interlacedly connected to the inner cavity of the mounting groove, through grooves are provided on both sides of the inner wall of the mounting groove, the limiting blocks are slidably and interlacedly connected to the inner cavity of the through groove, limiting grooves are provided on both sides of the fixing rod, and the limiting blocks are connected to the inner cavity of the limiting groove The cam is connected with the locking plate on one side of the locking plate, and the locking plate is fixedly connected with the locking plate on the other side of the locking plate.

[0007] Furthermore, the cross-sections of the mounting groove and the fixing rod are both rectangular.

[0008] Furthermore, the outer side of the handle is provided with anti-slip stripes.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. On the basis of the existing technical structure, firstly, by adding an electric push rod to drive the sealing plate to move upward, there is no need to lift the sealing plate manually, thus avoiding the phenomenon that manually lifting the sealing plate consumes a lot of manpower; secondly, by adding a handle, a torsion spring, a connecting block and a top plate, the two connecting rods can be moved at the same time by rotating the handle, so that when disassembling the stirring rod, it is convenient for the staff to complete the operation with one hand, making the disassembly of the stirring rod more convenient.

[0011] 2. Through the installation groove and the fixed rod with a rectangular cross-section, the rotating rod can directly drive the fixed rod to rotate, reducing the force on the limit block during rotation. When holding the handle and rotating it, the anti-slip stripes increase the friction with the hand to avoid slipping. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The cross-sections of the mounting groove and the fixing rod 6 are both rectangular.

[0021] The outer side of the handle 13 is provided with anti-slip stripes.

[0022] Working principle: In the utility model, when the dispersant and petroleum product in the mixing box 1 need to be stirred, the motor 4 is started to drive the rotating rod 5, and the fixed rod 6 is located in the installation groove and rotates synchronously with the rotating rod 5, and then the stirring rod 2 rotates synchronously with the rotating rod 5, and the stirring blades rotate synchronously with the stirring rod 2 to stir and mix the dispersant and the petroleum product. When the stirring rod 2 and the stirring blades need to be disassembled for cleaning, the electric push rod 12 is started to drive the sealing plate 3 to move upward until the stirring rod 2 is completely moved out of the mixing box 1. The staff member holds the handle 13 and rotates it, and the handle 13 drives the connecting block 16 to rotate. The elliptical connecting block 16 abuts against the two top plates 17 during rotation and pushes the top plates 17 away from the fixing frame 11 The top plate 17 drives the connecting rod 9 to move, the connecting rod 9 drives the fixing plate 8 to move, and the fixing plate 8 drives the limit block 7 to move until the limit block 7 moves out of the limit groove. At this time, the fixing rod 6 can be moved out of the installation groove, thereby completing the disassembly work. It should be noted that the rotation of the handle 13 will drive the torsion spring 15 to rotate. If the stirring rod 2 is subjected to the force of the torsion spring 15 and rotates with the handle 13, the wrist can be used to block the stirring blade at the top to prevent the stirring rod 2 from rotating, and the handle 13 can be rotated with the fingers. After the disassembly is completed, when the handle 13 is released, the torsion spring 15 is reset to drive the handle 13 to rotate in the opposite direction to reset it, and then the connecting block 16 is reset synchronously with the handle 13, which is convenient for reuse.
