Technical Field

[0001] This utility model relates to the field of petrochemical production technology, and in particular to a dual-stirring mixing device for petrochemical production. Background Technology

[0002] Petrochemicals is a processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. In today's global economy, the petrochemical industry plays a vital role, and its industrial chain covers a wide range from crude oil extraction to various chemical products.

[0003] Referring to the utility model patent with authorized publication number CN220478633U, a dual-stirring mixing device for petrochemical production is disclosed. This dual-stirring mixing device for petrochemical production includes a stirring tank, a top cover, a feed pipe, and a discharge pipe. The stirring tank has an inner tank inside, and the side surface and bottom surface of the inner tank are provided with several through holes. Two sliding rods and several equidistantly arranged second stirring blades are fixedly connected to the side surface of the inner tank. The inner tank is provided with a first rotating shaft, several equidistantly arranged first stirring blades, and several equidistantly arranged blades. The second rotating shaft and third stirring blades are provided below the inner tank. The two sliding rods are located on the front and rear sides of the inner tank, respectively. The stirring tank has a sliding groove inside, and the end of each sliding rod away from the inner tank is movably engaged with the sliding groove.

[0004] The aforementioned patent employs a two-rotating-body structure to drive the stirring of petroleum, along with a dual-motor drive system. Internal rotating components provide auxiliary support, and a through-hole is provided on the inner cylinder driven by the bottom motor. Given the high viscosity of petroleum, the internal stirring components of the aforementioned patent are too precisely integrated and have a complex structure, making them prone to jamming in actual production and resulting in unsatisfactory stirring effects. Therefore, we propose a dual-stirring mixing device for petrochemical production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual-stirring mixing device for petrochemical production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dual-stirring mixing device for petrochemical production includes a petrochemical processing tank. A top cover is provided at the top of the tank. A drive motor is fixedly installed on the upper end of the top cover. The output end of the drive motor rotates to the lower side of the top cover, and a shaft is connected to the output end of the drive motor via a coupling. A stirring rod is fixedly installed on the shaft, and an auxiliary stirring assembly is provided at the lower end of the stirring rod. The auxiliary stirring assembly includes a fixed cylinder, a sliding cylinder slidably installed inside the fixed cylinder, a bent rod fixedly installed on the side of the sliding cylinder, a long strip plate fixedly installed on the bent rod, a groove starting on the lower side wall of the shaft, and a sliding support fixedly installed on the inner wall of the sliding cylinder, the sliding support being slidably engaged with the inner side of the groove.

[0008] Preferably, the slide groove is arranged in a loop on the side wall of the rotating shaft and the slide groove is arranged in an arc slope in the vertical direction.

[0009] Preferably, the end of the sliding support is spherical.

[0010] Preferably, the elongated plate and the stirring rod are arranged in a cross configuration and do not interfere with each other.

[0011] Preferably, a limiting keyway is provided between the sliding cylinder and the fixed cylinder, and the fixed cylinder is fixedly installed on the bottom of the inner side of the petrochemical processing barrel.

[0012] Preferably, a snap-fit ​​ring groove is provided at the upper port of the slide cylinder, a sealing ring is provided at the upper port of the slide cylinder, and a snap-fit ​​foot that matches the snap-fit ​​ring groove is provided inside the sealing ring.

[0013] Preferably, the bottom of the petrochemical processing drum is equipped with a support column, the upper side of the petrochemical processing drum is equipped with a feeding pipe, and the lower side of the petrochemical processing drum is equipped with a discharge pipe.

[0014] Preferably, a positioning bolt is screwed onto the side wall of the top cover.

[0015] Compared with related technologies, the dual-stirring mixing equipment for petrochemical production proposed in this utility model has the following beneficial effects:

[0016] In this utility model, a dual-stirring mixing device for petrochemical production is described. Through the auxiliary stirring components, when the starting motor drives the rotating shaft and its stirring rods to stir inside the petrochemical processing tank, a chute is provided at the lower end of the rotating shaft. This chute engages with a sliding support inside the bottom sliding cylinder. As the rotating shaft rotates, the chute follows. Because the chute is arranged in an arc slope in the vertical direction and intersects along the side wall of the rotating shaft, when the chute rotates one revolution with the rotating shaft, the sliding support drives the sliding cylinder to complete one vertical movement. As the rotating shaft continues to rotate, the sliding cylinder drives the long strip plate on its side bend rod to vibrate back and forth between the stirring rods, enhancing the mixing effect of materials between the stirring rods. This improves the stirring efficiency of the petrochemical processing process and increases production efficiency. Furthermore, the simple structural design of each component prevents jamming during stirring. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Reference Figure 1-6 Please refer to the following: Figures 1-6 ,in, Figure 1 This is a three-dimensional structural diagram of a dual-stirring mixing device for petrochemical production proposed in this utility model. Figure 2 This is a schematic diagram of the internal three-dimensional structure of the top cover of a double-stirring mixing device for petrochemical production proposed in this utility model; Figure 3 This is a three-dimensional structural diagram of the top cover of a dual-stirring mixing device for petrochemical production proposed in this utility model. Figure 4 This is a partial perspective view of a dual-stirring mixing device for petrochemical production proposed in this utility model. Figure 5 This is a partially sectional perspective view of a dual-stirring mixing device for petrochemical production proposed in this utility model; Figure 6 This is a three-dimensional cross-sectional view of the sealing ring. A dual-stirring mixing device for petrochemical production includes: a petrochemical processing tank 1, a top cover 5 at the top opening of the petrochemical processing tank 1, a drive motor 6 fixedly mounted on the upper end of the top cover 5, the output end of the drive motor 6 drives to rotate to the lower side of the top cover 5 and the output end of the drive motor 6 is connected to a rotating shaft 8 by a coupling, a stirring rod 9 is fixedly mounted on the rotating shaft 8, and an auxiliary stirring component is provided at the lower end of the stirring rod 9.

[0026] In this method, the auxiliary stirring assembly includes a fixed cylinder 10, a sliding cylinder 11 slidably installed inside the fixed cylinder 10, a bent rod 12 fixedly installed on the side of the sliding cylinder 11, a long strip plate 13 fixedly installed on the bent rod 12, a groove 14 starting on the lower side wall of the rotating shaft 8, a sliding support 15 fixedly installed on the inner wall of the sliding cylinder 11, the sliding support 15 slidably engaging with the inner side of the groove 14, the groove 14 being arranged in a loop on the side wall of the rotating shaft 8 and the groove 14 being arranged in an arc slope in the vertical direction, the end of the sliding support 15 being spherical, and the long strip plate 13 being arranged intersectingly with the stirring rod 9 and the long strip plate 13 and the stirring rod 9 not interfering with each other.

[0027] With the above configuration, when the rotating shaft 8 rotates, it will drive the slide 14 to rotate synchronously. Since the sliding support 15 on the inner wall of the slide cylinder 11 is engaged and slids inside the slide 14, when the slide 14 rotates, it will drive the sliding support 15 to move up and down in the vertical direction. As a result, the slide cylinder 11 will synchronously drive the side strip plate 13 to shake between the stirring rods 9, which will increase the interlayer material exchange and mixing effect of the stirring rods 9 during stirring and improve the mixing efficiency.

[0028] In this method, a support column 2 is installed at the bottom of the petrochemical processing drum 1, a feeding pipe 3 is installed on the upper side of the petrochemical processing drum 1, and a discharge pipe 4 is installed on the lower side of the petrochemical processing drum 1.

[0029] Through the above-described configuration, the support column 2 provides overall support for the petrochemical processing drum 1.

[0030] In this configuration, positioning bolts 7 are screwed onto the side wall of the top cover 5.

[0031] With the above-mentioned setup, the top cover 5 is screwed onto the upper end of the petrochemical processing drum 1 by positioning bolts 7, which facilitates disassembly and inspection of the internal components of the petrochemical processing drum 1.

[0032] In this method, a limiting keyway 16 is provided between the sliding cylinder 11 and the fixed cylinder 10, and the fixed cylinder 10 is fixedly installed on the bottom of the inner side of the petrochemical processing barrel 1.

[0033] By setting the limit keyway 16 in the above manner, the slide cylinder 11 cannot rotate with the fixed cylinder 10.

[0034] In this method, a snap ring groove 18 is provided at the upper port of the slide cylinder 11, a sealing ring 17 is provided at the upper port of the slide cylinder 11, and a snap-fit ​​foot 19 that matches the snap ring groove 18 is provided inside the sealing ring 17.

[0035] With the above-described configuration, the sealing ring 17 is snapped onto the upper port of the slide cylinder 11 via the snap-fit ​​foot 19, ensuring a tight seal at the junction of the upper port of the slide cylinder 11 and the rotating shaft 8.

[0036] The working principle of the dual-stirring mixing device for petrochemical production provided by this utility model is as follows:

[0037] In use, the raw materials are added into the petrochemical processing drum 1 through the feeding pipe 3. The drive motor 6 is started and rotated. The drive motor 6 drives the rotating shaft 8 at the bottom of the top cover 5 and the stirring rod 9 on the rotating shaft 8 to rotate synchronously, thus mixing the materials. As the rotating shaft 8 rotates, the sliding groove 14 on its lower side wall rotates synchronously with it. Since the sliding cylinder 11 can only move up and down due to the limitation of the rotational freedom of the fixed cylinder 10, the sliding groove 14 drives the sliding support 15 on the inner wall of the sliding cylinder 11 to move up and down. With the continuous rotation of the rotating shaft 8, the sliding support 15 drives the sliding cylinder 11 and the long strip plate 13 on the side of the sliding cylinder 11 to shake up and down between the stirring rod 9, increasing the interlayer material exchange and mixing effect of the stirring rod 9 during mixing, and improving the mixing efficiency. After the mixing is completed, the discharge pipe 4 is opened and the mixed materials are discharged from the discharge pipe 4.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
