Description
Technical Field
[0001] The utility model relates to the technical field of water-based paint production equipment, in particular to a water-based paint mixing device. Background Art
[0002] Water-based paints are paints that use water as a solvent or dispersion medium. When a liquid solute is mixed with water, it is typically produced by stirring in a reactor.
[0003] The use of a reactor is not only costly but also requires a long stirring time and is relatively inefficient.
[0004] Therefore, how to reduce the production cost of water-based coatings and improve production efficiency has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content
[0005] In order to solve the technical problems in the background technology, the utility model discloses a water-based paint mixing device.
[0006] The utility model provides a water-based paint mixing device, comprising a vertically arranged cylinder;
[0007] A vertically arranged spiral channel is provided in the cylinder;
[0008] A connected feeding cavity is provided above the spiral channel, and a connected discharging cavity is provided below the spiral channel;
[0009] The feed chamber is provided with a first atomizing nozzle and a second atomizing nozzle arranged in parallel and opposite to each other; the first atomizing nozzle is used to spray water in the form of atomization, and the second atomizing nozzle is used to spray liquid solute in the form of atomization;
[0010] An air inlet connector is provided at the top of the feed chamber, and argon gas is sprayed into the cylinder from top to bottom through the air inlet connector;
[0011] A discharge joint is provided at the bottom of the discharge chamber for collecting finished products;
[0012] The solute and water are mixed in the atomized state, and enter the spiral channel for further mixing under the conveying action of argon gas, and finally enter the discharge chamber.
[0013] Under the action of the atomizing nozzle, the solute and water are sprayed out in opposite directions, which can improve their mixing efficiency. After the argon gas enters the feed chamber, it drives the solute, water, and the already mixed paint into the spiral channel. The spiral channel not only extends the path but also increases the flow rate of the argon gas, thereby accelerating the mixing of the solute and water. The mixed paint enters the discharge chamber and flows out of the discharge connector for collection. Compared with traditional reactors, this utility model is not only low-cost, but also shortens the mixing time of the solute and water, improves the mixing uniformity, and improves production efficiency.
[0014] In order to simplify the structure of the spiral channel, a further design is: a partition is provided in the cylinder, the partition is spirally shaped, so that it forms a spiral groove; the groove wall of the spiral groove abuts against the inner wall of the cylinder and forms a spiral channel between the inner wall of the cylinder.
[0015] To further enhance the mixing efficiency of water and solute, a throat tube is connected between the spiral channel and the feed chamber. The throat tube is symmetrical in structure, with its diameter increasing from the center to the sides. This reduces the flow area, allowing the argon gas to form a mixed flow within the feed chamber, thereby increasing the mixing speed of water and solute.
[0016] Because the paint exerts a strong force under the action of argon gas, collection is difficult. Therefore, a further improvement is to install a filter cloth between the spiral channel and the discharge chamber, separating them. The filter cloth blocks the airflow, and when the paint passes through the filter cloth, it forms droplets that drip downward. When the argon gas passes through the filter cloth, its speed is reduced, thus preventing impact on the collection container.
[0017] Since the filter cloth is relatively soft, it is difficult to install. Based on this, further improvements are made: the cylinder includes a cylinder body, and the partition is inserted into the cylinder body; a cylinder head is provided at the upper end of the cylinder body, and its interior constitutes a feed cavity; a cylinder bottom is provided at the lower end of the cylinder body, and its interior constitutes a discharge cavity; a connecting flange is provided at the lower end of the cylinder body; a lower flange is provided at the upper end of the cylinder bottom; the connecting flange and the lower flange are connected and fixed by fasteners; two orifice plates are sandwiched between the connecting flange and the lower flange; and the filter cloth is sandwiched between the orifice plates.
[0018] When the filter cloth is subjected to pressure from the orifice plate, it is easily damaged and its performance will be reduced. Based on this, a further improvement is that: a notch is provided at the center of the orifice plate; the notches are opposite to each other and form a placement cavity; the filter cloth is arranged in the placement cavity.
[0019] In order to facilitate the recovery of argon, a further design is that an outlet pipe is connected to the bottom of the cylinder to discharge the argon.
[0020] In order to prevent the paint from being discharged outward from the air outlet pipe, a further design is that the air outlet pipe is arranged obliquely upward.
[0021] The beneficial effects of this utility model are as follows: the solute and water are sprayed out in atomized form under the action of the atomizing nozzle, and in opposite directions, which can improve their mixing efficiency; after the argon gas enters the feed chamber, it drives the solute, water, and the already mixed paint into the spiral channel. The spiral channel not only extends the path but also increases the flow rate of the argon gas, thereby accelerating the mixing of the solute and water; the mixed paint enters the discharge chamber and flows out from the discharge connector for collection. Compared with traditional reactors, this utility model is not only low-cost, but also shortens the mixing time of the solute and water, improves the mixing uniformity, and improves production efficiency.

DETAILED DESCRIPTION
[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.
[0027] like Figure 1 As shown, the present invention provides a water-based paint mixing device comprising a vertically arranged cylinder 1. The cylinder 1 comprises a barrel 101, within which a partition 9 is inserted. The partition 9 is vertically arranged in a spiral shape, forming a spiral groove; the outer wall of the spiral groove abuts against the inner wall of the cylinder 1, secured by friction. The spiral groove and the inner wall of the cylinder 1 form a spiral channel 2.
[0028] The upper end of the barrel 101 is integrally connected with a throat 10 and a barrel head 102. The throat 10 is a symmetrical structure with a diameter increasing from the center to the upper and lower sides. The inside of the barrel head 102 constitutes a feed chamber 3. A first atomizing nozzle 5 and a second atomizing nozzle 6 with opposite spray directions and at the same height are installed on opposite sides of the barrel head 102. The first atomizing nozzle 5 is used to spray water in the form of atomization, and the second atomizing nozzle 6 is used to spray liquid solutes in the form of atomization. An air inlet connector 7 is installed on the top of the barrel head 102, and argon gas is sprayed into the barrel 1 from top to bottom through the air inlet connector 7.
[0029] The lower end of the cylinder body 101 is connected to the cylinder bottom 103, and the interior of the cylinder bottom 103 constitutes the discharge cavity 4. The lower end of the cylinder body 101 is provided with a connecting flange 104; the upper end of the cylinder bottom 103 is provided with a lower flange 105; the connecting flange 104 and the lower flange 105 are connected and fixed by fasteners. Figure 2As shown, two orifice plates 12 are sandwiched between the connecting flange 104 and the lower flange 105. Notches 121 are positioned at the centers of the orifice plates 12. These notches 121 face each other and form a cavity within which the filter cloth 11 is placed. This arrangement protects the filter cloth 11 from pressure from the orifice plates 12, maintaining a stable structure and performance. The orifice plates 12 and filter cloth 11 separate the spiral channel 2 from the discharge chamber 4. The spiral channel 2 and the discharge chamber 4 are also connected via the through-holes of the orifice plates 12 and the mesh of the filter cloth 11.
[0030] The bottom 103 of the cylinder is connected to an air outlet pipe 13 for discharging argon gas. The air outlet pipe 13 is arranged obliquely upward to prevent the paint from being discharged outward from the air outlet pipe 13.
[0031] The working principle of the present invention is as follows: the solute and water are atomized and sprayed out in opposite directions under the action of the atomizing nozzle, which improves their mixing efficiency. After the argon gas enters the feed chamber 3, it mixes with the atomized material and drives the solute, water, and already mixed paint into the throat 10 and spiral channel 2 in sequence. The throat 10 reduces the flow area, allowing the argon gas to form a mixed flow in the feed chamber 3, thereby increasing the mixing speed of the water and solute. The spiral channel 2 not only extends the path but also increases the flow rate of the argon gas, thereby accelerating the mixing of the solute and water. Before the mixed paint enters the discharge chamber 4, it is blocked by the filter cloth 11, eliminating the impact force. When the paint passes through the filter cloth 11, the impact force is reduced and the paint is discharged and collected through the outlet pipe 13, enabling reuse. This way, the paint is collected without causing any impact on the collection container. After entering the discharge chamber 4, the paint flows out through the discharge connector 8 for collection. Compared with the traditional reactor, the utility model not only has low cost, but also has a short mixing time of the solute and water, a higher mixing uniformity and a higher production efficiency.
[0032] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
