A dispensing device for rust preventive processing

Abstract

The present application relates to the field of liquid mixing equipment, especially to a blending device for processing rust preventive, comprising a rectangular welded water tank, further comprising: a sliding assembly consisting of a sliding plate and a guide rod inserted at both ends of the sliding plate in an "H" shape structure, both ends of the guide rod being fixedly connected with the welded water tank; and a bubble jetting assembly consisting of a connecting pipe and a "Y" shaped jet pipe connection, both ends of the connecting pipe being rotatably connected with the sliding plate. The present application replaces the traditional stirring tank with the welded water tank (reducing the cost of the degraded container), replaces the traditional stirring paddle with the forced disturbance of the liquid by blowing bubbles to float (the energy required for pumping gas to the shallow liquid level is smaller than that of the paddle direct stirring, so the energy consumption of the equipment is reduced), and uses compressed gas as the power source to utilize the blowing gas reaction force to push the nozzle to do the slow back-and-forth movement between both ends of the welded water tank (the mixture is uniform and sufficient, and the equipment is automated), thereby achieving the sufficient mixing of the liquid in the welded water tank.

[0002] Rust inhibitors contain industrial white oil and various additives. Compared with industrial pure water, the viscosity of rust inhibitors is relatively high, which is not conducive to traditional electrically driven paddle agitation equipment.

Detailed Implementation

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Example, refer to Figures 1-8 This embodiment provides a mixing device for processing rust inhibitors.

[0028] The present invention includes a rectangular welded water tank 100, and also includes a sliding assembly 200 and a bubble jet assembly 300; refer to Figure 2 The sliding assembly 200 consists of a sliding plate 201 and guide rods 202 inserted at both ends, forming an "H"-shaped structure. The sliding plate 201 is parallel to the wide side of the welded water tank 100, and the guide rods 202 are parallel to the long side of the welded water tank 100. Both ends of the guide rods 202 are fixedly connected to the welded water tank 100. (Reference) Figure 2 and Figure 3 The bubble jet assembly 300 consists of a connecting pipe 301 and a "Y"-shaped nozzle 302 connected together, with both ends of the connecting pipe 301 rotatably connected to the slide plate 201; Reference Figure 4 and Figure 6 One end of the nozzle 302 is fixedly connected to the connecting pipe 301 with a core 304. Both ends of the nozzle 302 at the cross connection points are provided with perforated baffles 3021. The core 304 is slotted and hinged with a swing arm 305. One end of the swing arm 305 is hinged with two cover plates 306 for sealing the baffles 3021. (Ref. 5) Figure 7 The other end of the swing arm 305 is T-shaped, with short pull wire 1 307 and short pull wire 2 308 respectively attached to its two short sides and passing through the connecting tube 301. The outer peripheral wall of the insert 304 is fitted with an elastic rubber ring 309 at the T-shaped end of the swing arm 305. Pull ropes 203 are provided between the two ends of the two guide rods 202. Limiting clamps 204 are fixed at the ends of the two pull ropes 203 that are far apart from each other. Long pull wires 310 are slidably connected to the two pull ropes 203, and the two long pull wires 310 are fixedly connected to short pull wire 1 307 and short pull wire 2 308 respectively.

[0029] Specifically, the lengths from the connection point between all short guy wires 307 and long guy wires 310 to the end of short guy wire 307, and the lengths from the connection point between all short guy wires 308 and long guy wires 310 to the end of short guy wire 308, are all equal; (Reference) Figure 4 A short rod 3012 is fixedly inserted into one end of the connecting pipe 301 through the support 205 along its end radially. The support 205, through which the connecting pipe 301 passes, has two limiting screws 2051 fixedly connected to its side wall in the rotation path of the short rod 3012, so that the maximum deflection angle of the nozzle 302 from vertical to both sides is sixty degrees.

[0030] This invention provides a mixing device for rust inhibitor processing. The main function is to achieve mixing by using rising air bubbles to agitate the liquid. Specifically, unlike traditional paddle agitation that directly drives the liquid, the resistance encountered by paddle agitation is not significantly related to the depth of the paddle below the liquid surface, but rather to the paddle shape and liquid viscosity. When pumping gas into the liquid, the most significant factor affecting resistance is the depth of the exhaust point below the liquid surface, which is strongly correlated with liquid pressure. Therefore, based on these fundamental physical characteristics, this invention proposes a method that replaces the traditional mixing tank with a welding water tank 100 (reducing container downgrading costs), replaces the traditional agitator paddles with forced agitation by rising air bubbles (requiring less energy to pump gas into shallow liquid levels compared to direct paddle agitation, reducing equipment energy consumption), and uses compressed air as a power source to drive the nozzle 303 in a slow reciprocating motion between the two ends of the welding water tank 100 using the reaction force of the blowing air (resulting in uniform and thorough mixing, and automated equipment), thereby achieving thorough mixing of the liquid in the welding water tank 100. Before explaining the specific working principle, let me first clarify the scope of application of this invention. The production method of this invention is not suitable for processing liquids that are prohibited from containing air bubbles, such as hydraulic oil. It is only suitable for liquids that are not sensitive to the presence of tiny air bubbles or for which the air bubble content can be made to meet the production standard by simple means such as letting them stand.

[0031] First refer to Figure 1 This invention requires a row of nozzles 302 to reciprocate within the welding water tank 100, thereby thoroughly mixing the rust inhibitor throughout the welding water tank 100. Figure 1 and Figure 4Taking the perspective as an example, the "Y"-shaped nozzle 302 is tilted to the right at a 60-degree angle, causing one nozzle 303 to spray horizontally to the right and the other nozzle 303 to spray obliquely upward. At this time, the spray reaction force of the two nozzles 303 pushes the bubble spray assembly 300 and the slide plate 201 to the left. At the same time, the gravity of the steel nozzle 302 and the nozzle 303 causes the nozzle 302 to continue to deflect downward to the right. Since the short rod 3012 on the connecting pipe 301 abuts against the limit screw 2051 on the right, it prevents the nozzle 302 from continuing to deflect downward to the right. Only in this way can the spray angle of the nozzle 302 be maintained, thereby causing the bubble spray assembly 300 and the slide plate 201 to slide towards the left end of the welded water tank 100. by Figure 6 and Figure 8 Taking a perspective example, when the lower end of the swing arm 305 swings to the right, the top end of the swing arm 305 will press the left cover plate 306 onto the left partition plate 3021, sealing the hole on the partition plate 3021. (Refer to...) Figure 4 Correspondingly, the seal blocks the nozzle 303 that sprays obliquely upwards. At this time, only the nozzle 303 that sprays horizontally to the right works (the number of nozzles 303 decreases, and the working pressure of the remaining nozzles 303 will increase accordingly). The balance is broken. The axis of a single nozzle 303 does not intersect with the rotation axis of the connecting pipe 301. It will generate a thrust on one side of the rotation axis of the connecting pipe 301, thereby overcoming the gravity of the nozzle 302 and the nozzle 303 and the rotational resistance of the connecting pipe 301 in the rust inhibitor. This causes the connecting pipe 301, the nozzle 302 and the nozzle 303 to tend to deflect to the left around the rotation axis of the connecting pipe 301. To achieve the target action described above, the present invention also needs to meet the following conditions: When the skateboard 201 moves to the appropriate position (both ends of the welded water tank 100), the swing arm 305 overcomes the binding force of the rubber ring 309 on the neutral position of the swing arm 305, forcing the swing arm 305 to deflect in the desired direction. (Refer to...) Figure 8 If the right side is defined as short pull line 2 308, then the left side is short pull line 1 307. At this time, short pull line 2 308 is in a relaxed state, and short pull line 1 307 is in a tightened state, which forces the bottom end of the swing arm 305 to swing to the right, thereby sealing the partition 3021 on the left. Conversely, if short pull line 1 307 is loosened and short pull line 2 308 is tightened, the lower end of the swing arm 305 will deflect to the left and seal the partition 3021 on the right. refer to Figure 2Both pull ropes 203 have a limit clamp 204 fixed at one end. When the slide plate 201 slides along the guide rod 202 to either end, one of the long pull wires 310 will eventually come into contact with the sliding connection point of the pull rope 203 against the limit clamp 204. When the slide plate 201 continues to move under the thrust of the nozzle 303 and the action of inertia, the long pull wire 310 will be pulled to the outside of the connecting pipe 301. The long pull wire 310 pulls the short pull wire 1 307 or the short pull wire 2 308, thereby forcing the swing arm 305 to deflect against the binding force of the rubber ring 309. Since only one end of each pull rope 203 is fixed with the limit clamp 204, only one long pull wire 310 is triggered at a time. Specifically, considering the interference of objective factors such as processing and assembly precision, it is difficult for short pull wire 1 307 or short pull wire 2 308 to press the cover plate 306 onto the partition plate 3021 completely synchronously and fully. In this invention, the pull wire operation mainly serves to reduce the gap between the cover plate 306 and the partition plate 3021. The full sealing of the cover plate 306 onto the partition plate 3021 mainly depends on the forced increase in the airflow velocity when the gap between the cover plate 306 and the partition plate 3021 is reduced. The fluid velocity is inversely proportional to the pressure, thereby causing the cover plate 306 to actively adhere to the partition plate 3021. Subsequently, the pressure difference inside and outside the nozzle 302 is relied upon to maintain the close and sealed state of the cover plate 306 onto the partition plate 3021. This invention also relates to the following technical details: Firstly, refer to Figure 3 The slide plate 201 is horizontally set. The two ends of the slide plate 201 are clamped to the linear bearings through the ring part in the "P" shaped structure. The linear bearings are slidably connected to the guide rod 202. The two ends of the connecting pipe 301 are rotatably connected to the support 205 through the bearings. The two supports 205 are respectively fixedly connected to the two ends of the top surface of the slide plate 201. The side wall of the connecting pipe 301 is connected to the compressed air hose 313. Secondly, refer to Figure 2 and Figure 4 The outer wall of the connecting pipe 301 is provided with threaded interfaces 3011 in a straight array. The axial direction of the threaded interfaces 3011 is perpendicular to the axis of the connecting pipe 301. The nozzle 302 is sealed and fastened to the threaded interfaces 3011. Each nozzle 302 has a unidirectional nozzle 303 at the two interfaces away from the connecting pipe 301. The spray angle between the two nozzles 303 in a single nozzle 302 is 60 degrees. Each nozzle 303 has a backflow prevention function to prevent the rust inhibitor from flowing back into the nozzle 302. Thirdly, refer to Figure 6 The hinge position of the swing arm 305 and the cover plate 306 is located at the center of the cover plate 306, and the hinge axis of the swing arm 305 and the insert 304, as well as the hinge axis of the swing arm 305 and the cover plate 306, are parallel to the axis of the connecting pipe 301.

[0032] Fourth, refer to Figure 5 Both ends of the connecting pipe 301 have machined finish surfaces 3013 on their inner walls. The finish surfaces 3013 are sealed and slidably connected to pistons 311. The two ends of the pistons 311 that are far apart from each other are abutted against the ends of the connecting pipe 301 by springs 312. Two long pull wires 310 pass through the two pistons 311 respectively, and the long pull wires 310 are fixedly and sealedly connected to the pistons 311 they are connected to. This design aims to solve the problem of dynamic sealing between the pull wire and the connecting tube 301 during the operation of the pull wire in this invention. Dynamic sealing is achieved through the piston 311 and the precision-machined surface 3013. Because the compressed air inside the connecting pipe 301 has a high pressure, the piston 311 is elastically supported by the spring 312, which can prevent the piston 311 from moving towards the end of the connecting pipe 301 due to pressure difference and causing abnormal tightening of the long pull cable 310. When the long pull cable 310 is triggered to tighten, the piston 311 compresses the spring 312 to allow the long pull cable to work normally.

[0033] In summary, this invention achieves thorough mixing of the liquid in the welding water tank 100 by replacing the traditional mixing tank (reducing container downgrading costs), replacing the traditional stirring blades with forced agitation of the liquid by blowing air bubbles (requiring less energy to pump air to shallow liquid levels compared to direct stirring by blades, thus reducing equipment energy consumption), and using compressed air as a power source to drive the nozzle 303 to make a slow reciprocating motion between the two ends of the welding water tank 100 using the reaction force of blowing air (ensuring uniform and thorough mixing, and automating the equipment). This effectively solves the problem of high energy consumption in existing electrically driven blade stirring equipment when stirring rust inhibitors with high viscosity.
