Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a raw material mixing device for the production of water-based additives. Background Technology

[0002] In the production of water-based additives, the uniformity and efficiency of raw material mixing directly affect product performance and production cycle.

[0003] A mixing device for raw materials used in the production of water-based additives typically consists of a mixing tank, a multi-functional stirring system, an intelligent temperature control module, an online detection unit, and an automatic control system. The mixing tank adopts a conical or elliptical bottom structure, with polished inner walls to reduce material retention. The multi-functional stirring system integrates a low-speed anchor-type stirring paddle, a high-speed shear emulsifying head, and guide baffles, and can switch operating modes according to the characteristics of the raw materials. The intelligent temperature control module achieves steam heating / cold water cooling through a jacket or coil, with a temperature control accuracy of ±0.5℃. The online detection unit includes an ultrasonic particle size analyzer and a conductivity sensor to monitor the mixing uniformity and reaction progress in real time. The automatic control system is based on a PLC program and can preset mixing parameters and dynamically adjust variables such as stirring speed, temperature, and time.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Traditional mixing devices mostly rely on the rotation of a single set of stirring paddles at the top to form a single horizontal or vertical flow field, which makes it difficult to achieve all-round mixing of materials. This results in uneven mixing of water-based additive raw materials, and even stratification in some areas, affecting the stability of product quality. In view of this, we propose a raw material mixing device for the production of water-based additives. Utility Model Content

[0005] The purpose of this invention is to provide a raw material mixing device for the production of water-based additives, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A raw material mixing device for the production of water-based additives includes a mixing tank, a lid snapped onto the top of the mixing tank, a reinforcing ring fixedly mounted on the mixing tank, a bracket fixedly mounted on the reinforcing ring, and a mixing assembly disposed on the mixing tank, the mixing assembly comprising:

[0008] A feeding funnel, one end of which is fixedly installed on the cover, and a feeding pipe is fixedly installed on the other end of the feeding funnel. A mounting bracket is fixedly installed on the cover.

[0009] A servo motor is fixedly mounted on the mounting bracket. A straight rod is fixedly mounted on the output end of the servo motor. A flat paddle is fixedly mounted on the straight rod. A reciprocating cylinder is fixedly mounted on the bottom of the mixing tank.

[0010] A bottom motor is fixedly installed at the other end of the reciprocating drum. A vertical rod is fixedly installed at the output end of the bottom motor. An auger paddle is fixedly installed on the vertical rod. A discharge pipe is fixedly installed on the reciprocating drum, and a valve is provided on the discharge pipe.

[0011] In a further embodiment, multiple sets of the feed funnel, feed pipe, and flat paddle are provided.

[0012] In a further embodiment, the flat paddle is located inside the mixing tank, the auger paddle is located inside the reciprocating cylinder, and the auger paddle is located below the flat paddle.

[0013] In a further embodiment, the discharge pipe is located at the bottom of the reciprocating cylinder, and the horizontal height of the discharge pipe is lower than that of the reciprocating cylinder.

[0014] In a further embodiment, the mixing tank is provided with an auxiliary component, which includes a mounting shell. The mounting shell is fixedly mounted on the mixing tank, and an auxiliary motor is fixedly mounted on the mounting shell. A short rod is fixedly mounted on the output end of the auxiliary motor, and a propeller is fixedly mounted on the short rod. A mounting rod is fixedly mounted on the other end of the straight rod, and a mixing rod is fixedly mounted on the mounting rod.

[0015] In a further embodiment, multiple sets of the short rod, propeller, mounting rod, and stirring rod are provided, and these multiple sets of the short rod, propeller, mounting rod, and stirring rod are arranged inside the mixing tank.

[0016] In a further embodiment, the mounting rod and stirring rod are positioned below the horizontal paddle and above the auger paddle. The propeller is positioned on both sides of multiple sets of mounting rods and stirring rods, and the rotation direction of the propeller is opposite to that of the stirring rod. Multiple sets of propellers are evenly distributed around the circumference of the mixing tank.

[0017] Compared with the prior art, this utility model provides a raw material mixing device for the production of water-based additives, which has the following beneficial effects:

[0018] 1. This raw material mixing device for the production of water-based additives is equipped with a stirring component to ensure the stability of the production quality of water-based additives. This component, in conjunction with a servo motor-driven rod, drives multiple sets of flat paddles to rotate at high speed, forming a horizontal shear flow in the middle of the mixing tank. This quickly disperses the raw materials that have just been added through the feed funnel and feed pipe. The bottom motor drives the auger paddle on the vertical rod to rotate inside the reciprocating drum. The spiral structure of the auger paddle transports the material at the bottom of the drum upwards, where it merges with the flow field generated by the flat paddles, forming a three-dimensional mixing effect that circulates from top to bottom. This prevents material sedimentation and uneven mixing. At the same time, the discharge pipe is located at the bottom of the reciprocating drum, below the horizontal height of the drum body. When the mixing is completed, the valve is opened, and the mixed material can be quickly discharged under the pushing action of the auger paddle.

[0019] 2. This raw material mixing device for the production of water-based additives incorporates an auxiliary component to improve mixing quality and efficiency. This component, in conjunction with an auxiliary motor, drives a short rod to rotate a propeller, generating an axial propulsive flow on both sides of the mixing tank. This pushes the edge material towards the center area, solving the problem of dead zones in edge mixing that often occurs in traditional mixing methods. The mounting rod at the lower end of the straight rod and the mixing rod are located between the horizontal blade and the auger blade. The staggered distribution of the mixing rods generates irregular vortices when the straight rod rotates. These vortices superimpose with the propulsive flow of the propeller, the shear flow of the horizontal blade, and the circulating flow of the auger blade, forming a complex three-dimensional turbulent field.

Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A raw material mixing device for the production of water-based additives includes a mixing tank 1, a cover 2 snapped onto the top of the mixing tank 1, a reinforcing ring 3 fixedly installed on the mixing tank 1, and a bracket 4 fixedly installed on the reinforcing ring 3.

[0033] In one embodiment of this utility model, a stirring assembly 5 is provided on the stirring tank 1. The stirring assembly 5 includes a feeding funnel 51. One end of the feeding funnel 51 is fixedly installed on the cover 2, and a feeding pipe 52 is fixedly installed on the other end of the feeding funnel 51. A mounting bracket 53 is fixedly installed on the cover 2, and a servo motor 54 is fixedly installed on the mounting bracket 53. One end of a straight rod 55 is fixedly installed on the output end of the servo motor 54, and a flat paddle 56 is fixedly installed on the straight rod 55. One end of a reciprocating cylinder 57 is fixedly installed at the bottom of the stirring tank 1, and a bottom plate is fixedly installed at the other end of the reciprocating cylinder 57. A motor 58 is installed at the bottom. A vertical rod 59 is fixedly installed at the output end of the motor 58. An auger paddle 510 is fixedly installed on the vertical rod 59. A discharge pipe 511 is fixedly installed on the reciprocating cylinder 57. A valve 512 is installed on the discharge pipe 511. Multiple sets of feeding funnel 51, feeding pipe 52 and flat paddle 56 are provided. The flat paddle 56 is located inside the mixing tank 1. The auger paddle 510 is located inside the reciprocating cylinder 57. The auger paddle 510 is located below the flat paddle 56. The discharge pipe 511 is located at the bottom of the reciprocating cylinder 57. The horizontal height of the discharge pipe 511 is lower than that of the reciprocating cylinder 57.

[0034] In this embodiment, the main raw material is first poured into the mixing tank 1, then the lid 2 is closed, and then the servo motor 54 and the bottom motor 58 in the mixing assembly 5 are started. At the same time, the auxiliary materials required for the production of water-based additives are put into the mixing tank 1 through the feed pipe 52 and the feed funnel 51. Simultaneously, the output end of the servo motor 54 drives the straight rod 55 to rotate at high speed, and the multiple sets of flat paddles 56 fixed on the straight rod 55 rotate accordingly, forming a horizontal shear flow in the middle of the mixing tank 1. This shear flow can quickly disperse the newly added raw materials and auxiliary materials, so that the raw materials and auxiliary materials are initially mixed in the tank. At the same time, the output end of the bottom motor 58 drives the vertical rod 59 to rotate, and the auger paddle 510 on the vertical rod 59 rotates in the reciprocating cylinder 57. The spiral structure of the auger paddle 510 plays a role in conveying the material at the bottom of the mixing tank 1 upward, which merges and merges with the horizontal shear flow generated by the flat paddles 56, so that the material forms a three-dimensional mixing effect of up and down circulation in the mixing tank 1, effectively avoiding the problem of uneven mixing caused by material sedimentation.

[0035] In one embodiment of this utility model, an auxiliary component 6 is provided on the mixing tank 1. The auxiliary component 6 includes a mounting shell 61, which is fixedly mounted on the mixing tank 1. An auxiliary motor 62 is fixedly mounted on the mounting shell 61. A short rod 63 is fixedly mounted on the output end of the auxiliary motor 62. A propeller 64 is fixedly mounted on the short rod 63. An installation rod 65 is fixedly mounted on the other end of the straight rod 55. A stirring rod 66 is fixedly mounted on the installation rod 65. Multiple sets of short rods 63, propellers 64, installation rods 65, and stirring rods 66 are provided. Multiple sets of short rods 63, propellers 64, installation rods 65, and stirring rods 66 are provided inside the mixing tank 1. The installation rods 65 and stirring rods 66 are located below the flat paddle 56 and above the auger paddle 510. The propellers 64 are located on both sides of the multiple sets of installation rods 65 and stirring rods 66. The rotation direction of the propellers 64 is opposite to that of the stirring rods 66. The multiple sets of propellers 64 are evenly distributed around the circumference of the mixing tank 1.

[0036] In this embodiment, while the stirring assembly 5 is running, the auxiliary motor 62 in the auxiliary assembly 6 is activated. The output of the auxiliary motor 62 drives the short rod 63 to rotate, and the propeller 64 on the short rod 63 rotates accordingly, generating an axial propulsion flow on both sides of the stirring tank 1. This propulsion flow pushes the material at the edge of the stirring tank 1 towards the center area, solving the problem of dead zones at the edges that are prone to occur in traditional stirring. The mounting rod 65 and stirring rod 66, fixed at the other end of the straight rod 55, are located between the flat paddle 56 and the auger paddle 510. When the straight rod 55 rotates, the staggered stirring rods 66 move accordingly, generating irregular vortices. The eddies, propulsive flow from propeller 64, shear flow from horizontal blade 56, and circulating flow from auger blade 510 superimpose with each other to form a complex three-dimensional turbulent field within the mixing tank 1. Under the action of this turbulent field, the raw materials can be mixed more thoroughly, greatly improving the mixing quality and efficiency. When the raw materials have been mixed to the desired effect, valve 512 on the discharge pipe 511 is opened. Since the discharge pipe 511 is located at the bottom of the reciprocating cylinder 57 and its horizontal height is lower than that of the reciprocating cylinder 57, the mixed material is quickly discharged from the discharge pipe 511 under the pushing action of the continuously rotating auger blade 510 and enters the subsequent production process.

[0037] All electrical components mentioned in this application are electrically connected to the PLC controller and 220V AC mains power. The PLC controller is a conventional and known device that can control the servo motor 54, the bottom motor 58, and the auxiliary motor 62. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding, which are mature in the prior art. The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. The supporting structures of the hydraulic drive structure mentioned in this application, such as the hydraulic tank and the hydraulic pump, are existing equipment and will not be described in detail here.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
