Description

Technical Field

[0001] This utility model relates to the field of antifreeze preparation technology, specifically to a mixing device for antifreeze preparation. Background Technology

[0002] In the antifreeze preparation process, a premixing process is usually used to ensure that solid additives (such as specific types of corrosion inhibitors and buffers) are uniformly dispersed in the main solvent (such as ethylene glycol and water). That is, the solid particulate additives are first premixed with a portion of the solvent in a small premixing tank to form a homogeneous slurry or concentrate, and then transferred to the main preparation tank for final blending.

[0003] Currently, the common practice is to directly pour solid particulate materials into the liquid in the premixing tank. Due to the high density and inertia of the particulate materials, they tend to settle rapidly and accumulate at the bottom of the tank after contacting the liquid surface. The fluid shear force and circulation generated by conventional stirring devices are insufficient to effectively and promptly impact and break up the dense sediment layer formed at the bottom of the tank. This settling and accumulation phenomenon causes particles to pile up at the bottom of the tank, drastically reducing the effective contact area with the solvent, thus slowing down the dissolution process, prolonging the premixing time, and reducing production efficiency. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a mixing device for antifreeze preparation.

[0005] The technical solution of this utility model is as follows: A mixing device for preparing antifreeze includes a premixing tank, a stirring assembly and a drive motor connected thereto on the premixing tank, the premixing tank having an inlet and an outlet, and a material dispersing unit located on the upper inner side of the premixing tank near the inlet. The material dispersing unit includes a support connected to the inner wall of the premix tank, a vibrating motor mounted on the support, and a perforated guide frame. The perforated guide frame includes a guide cylinder and a distribution frame connected vertically. The upper end of the guide cylinder is provided with a feeding port, and the distribution frame has several guide holes with a diameter larger than the particle size of the material.

[0006] The connection structure between the guide cylinder and the support is as follows: the support has a mounting hole on the side away from the vibrating motor that matches the guide cylinder. The guide cylinder is vertically adjustable within the mounting hole and can be mounted on the mounting hole via an overlapping connector. The stirring assembly pre-stirs the solvent in the premixing tank. The granular additive material is fed into the perforated feed frame through the feeding port. Under the vibration of the vibrating motor, the feed frame disperses the fed material, which then falls into the premixing tank through the feed holes. The stirring assembly then mixes the additive material and solvent evenly, reducing the occurrence of material clumping or failure to disperse and mix well with the solvent.

[0007] The guide tube can be overlapped in the mounting hole. The guide tube is a long structure. Multiple threaded holes are opened on both sides of the guide tube along its length. The threaded holes are connected to the overlapping parts by threads.

[0008] The specific structure of the lap joint is as follows: the lap joint includes an integrally formed nut and a screw rod. The screw rod includes a first threaded section, a smooth section and a second threaded section arranged sequentially from the side closest to the nut to the other side. The first threaded section and the second threaded section can be threadedly connected to two threaded holes on the same horizontal plane on opposite sides of the guide cylinder, so that the lap joint is connected to the guide cylinder and the lap joint limits the position of the guide cylinder in the mounting hole.

[0009] Furthermore, the first threaded segment and the second threaded segment have the same structure, and the length of the first threaded segment is greater than the length of the threaded hole.

[0010] To reduce the number of turns required for tightening the lap joint and enable quick installation of the lap joint into the appropriate mounting hole, the length ratio of the smooth section to the first threaded section is 3-5.

[0011] The specific structure of the perforated guide frame is that it is an arc-shaped structure pointing downwards, and the maximum length of the perforated guide frame is greater than the width or thickness of the guide cylinder.

[0012] To facilitate the uniform dispersion of granular materials on the bottom surface of the perforated feeder frame, the vibrating motor evenly disperses the materials before they fall into the premix tank through the feeder holes, reducing the occurrence of material clumping or uneven dispersion. The feeder frame is equipped with through feeder holes on both the lower and upper surfaces.

[0013] To avoid interference between the perforated feeder frame and the mixing assembly, the feeder frame is positioned at a height higher than the topmost mixing blade of the mixing assembly within the premixing tank.

[0014] Preferably, the support has a T-shaped cross-section, and the side of the support near the inner wall of the premix tank is adapted to the curvature of the inner wall of the premix tank.

[0015] The beneficial effects of this utility model are as follows: Through a material dispersing unit located below the feed inlet, a vibrating motor drives a perforated guide mesh frame to vibrate at high frequency. When granular additives are fed into the feed inlet, they first fall onto the distribution mesh frame. The vibration instantly disperses the aggregated granular material, which is then evenly and dispersed into the solvent in the premixing tank through the guide holes. This process avoids the problem of granular material rapidly settling at the bottom of the tank and forming a dense sediment layer due to direct feeding, allowing the stirring components to more efficiently stir and dissolve the material. This greatly reduces material clumping and uneven dispersion, significantly shortens the premixing time, and improves production efficiency and the consistency of the final antifreeze product quality. The material distribution frame adopts a downward arc-shaped structure, and guide holes are opened on both its upper and lower surfaces to increase the material dispersion area.

Detailed Implementation

[0017] See Figure 1 , Figure 2 and Figure 3 As shown, a mixing device for preparing antifreeze includes a premixing tank 1. The premixing tank 1 is equipped with a stirring assembly 2 and a drive motor 3 connected thereto. The stirring assembly 2 is located inside the premixing tank 1 and includes a stirring shaft 201 and multiple stirring blades 202 mounted on the stirring shaft 201. The upper end of the stirring shaft 201 is connected to the output end of the drive motor 3 via a connector. The drive motor 3 can drive the stirring shaft 201 to rotate, thereby causing the stirring blades 202 to stir the solvent and additives inside the premixing tank 1. Both the stirring assembly 2 and the drive motor 3 are prior art. The drive motor 3 is located on the upper outer part of the tank cover of the premixing tank 1. The premixing tank 1 has an inlet 101 and an outlet 102. The inlet 101 is located on one side of the tank cover. A material dispersing unit is located on the upper inner side of the premixing tank 1 near the inlet 101.

[0018] See Figure 4 and Figure 5As shown, the material dispersing unit includes a support 4 connected to the inner wall of the premix tank 1, a vibrating motor 5 mounted on the support 4, and a perforated guide mesh frame 6. The vibrating motor 5 is a waterproof type, which is existing technology. The support 4 has a T-shaped cross-section, and the side of the support 4 closest to the inner wall of the premix tank 1 is adapted to the curvature of the inner wall of the premix tank 1. The T-shaped cross-section of the support 4, which is adapted to the curvature of the inner wall of the tank, ensures the connection strength while making it stable and able to fully withstand the load of the vibrating motor 5 during operation, thus extending the service life of the equipment.

[0019] The width of the support 4 can be selected according to the tank capacity and the distance from the stirring shaft 201. It can be as close as possible to the side of the stirring shaft 201 so that the guide cylinder 601 on it is close to the stirring shaft 201 and the material distribution frame 602 does not contact the stirring shaft 201 and the stirring blade 202, which is conducive to the material falling to the middle of the premixing tank 1 for uniform mixing with the solvent.

[0020] The perforated feed guide frame 6 includes a guide cylinder 601 and a distribution frame 602 connected vertically. The upper end of the guide cylinder 601 is provided with a feeding port, and the distribution frame 602 has several feed guide holes 6021 with a diameter larger than the particle size of the material. To avoid interference between the perforated feed guide frame 6 and the mixing assembly 2, the height of the distribution frame 602 in the premix tank 1 is higher than the height of the uppermost mixing blade 202 of the mixing assembly 2.

[0021] The support 4 has a mounting hole on the side away from the vibration motor 5 that is compatible with the guide cylinder 601. The guide cylinder 601 is adjustable in the vertical direction in the mounting hole and can be mounted on the mounting hole by means of the overlapping part 7.

[0022] In the above structure, the stirring component 2 pre-stirs the solvent in the premix tank 1. The granular additive material is fed into the perforated guide frame 6 through the feeding port. Under the vibration of the vibrating motor 5, the distribution frame 602 disperses the fed material. The dispersed material falls into the premix tank 1 through the guide hole 6021. The stirring component 2 agitates the additive material and solvent, achieving uniform mixing and reducing the occurrence of material clumping or failure to disperse and mix well with the solvent. The additive, after being mixed in the premix tank 1, is connected to the antifreeze tank outside through the discharge port 102 and a connecting pipe, where it is mixed with the solvent in the antifreeze tank to produce antifreeze. The connection structure between the premix tank 1 and the antifreeze tank is a conventional technology and is not shown in the figure.

[0023] The guide cylinder 601, which can overlap the mounting hole, has an elongated structure. Multiple threaded holes 6011 are provided on both sides along its length, and overlapping members 7 are internally threaded into these holes 6011. Through the adjustable connection design between the guide cylinder 601 and the mounting hole on the support 4, and specifically by using the overlapping members 7 with a first threaded section 7021, a smooth rod section 7022, and a second threaded section 7023 for fixation, the overall height of the perforated material guide frame 6 can be flexibly adjusted. Operators can quickly adjust the frame to the optimal working position according to the characteristics of different batches of materials and the liquid level, optimizing the dispersing effect and improving the applicability and ease of operation of the device.

[0024] See Figure 5 and Figure 6 As shown, the lap joint 7 includes an integrally formed nut 701 and a screw 702. The screw 702 includes a first threaded section 7021, a smooth section 7022, and a second threaded section 7023 arranged sequentially from one side near the nut 701 to the other. The first threaded section 7021 and the second threaded section 7023 have the same structure, and the length of the first threaded section 7021 is greater than the length of the threaded hole 6011. The first threaded section 7021 and the second threaded section 7023 can be threadedly connected to two threaded holes 6011 located on the same horizontal plane on opposite sides of the guide cylinder 601, so that the lap joint 7 is connected to the guide cylinder 601, and the lap joint 7 limits the position of the guide cylinder 601 in the mounting hole.

[0025] The length ratio of the smooth section 7022 to the first threaded section 7021 is 3-5. This arrangement ensures that the first threaded section 7021 occupies a smaller proportion of the total length of the screw 702, while the smooth section 7022 occupies a larger proportion. This minimizes the number of turns while ensuring connection strength, allowing the lap joint 7 to be quickly installed in the appropriate mounting hole for rapid adjustment and locking.

[0026] The perforated material guide frame 6 has the following specific structure: it is an arc-shaped structure pointing downwards, and its maximum length is greater than the width or thickness of the guide cylinder 601. The material distribution frame 602 adopts an arc-shaped structure pointing downwards, which increases the material dispersion area.

[0027] To facilitate the uniform dispersion of granular materials on the bottom surface of the perforated feeder frame 6, the vibrating motor 5 disperses the materials evenly, and the materials fall into the premix tank 1 through the feeder holes 6021, thereby reducing the phenomenon of material clumping or uneven dispersion, the feeder frame 602 is provided with through feeder holes 6021 on both the lower and upper surfaces.
