Afterward, the glass is placed in a heat treatment process and heated to above the melting point of the nitrate, turning it into molten salt. However, existing spraying equipment cannot guarantee the uniformity of the sprayed salt, affecting the strengthening effect. Utility Model Content

[0019] Explanation of reference numerals in the attached figures: Detailed Implementation

[0020] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0021] The spraying device and salt spraying drying equipment of this utility model are described below with reference to the accompanying drawings.

[0022] like Figures 1 to 3As shown, this utility model provides a spraying device, wherein the spraying device 01 includes a spray valve 10, the spray valve 10 includes a valve body 100, a liquid flow channel 110 and a vibrating element 150, the liquid flow channel 110 includes an inlet 111 and an outlet 112, the liquid flow channel 110 passes through the valve body 100, the vibrating element 150 is sleeved on the outside of the liquid flow channel 110 and can transmit vibration to the liquid in the liquid flow channel 110, the spraying device 01 is provided with a gas flow channel 120, the gas outlet 127 of the gas flow channel 120 is arranged around the outlet 112 and can spray gas to atomize the liquid flowing out of the outlet 112.

[0023] When the above-mentioned spraying device 01 is used, since the liquid flow channel 110 is connected to the valve body 100 of the spray valve 10, the liquid flow channel 110 includes an inlet 111 and an outlet 112. A vibrating element 150 that can generate vibration is sleeved on the outside of the liquid flow channel 110, which can transmit vibration to the liquid in the liquid flow channel 110, so that the liquid resonates and inhibits the precipitation and aggregation of the liquid, ensuring the uniform distribution of the liquid. At the same time, the spraying device 01 is also provided with an air flow channel 120. The air outlet 127 of the air flow channel 120 is arranged around the outlet 112 and can spray gas to atomize the liquid flowing out of the outlet 112, thereby ensuring the uniformity of the salt spraying operation.

[0024] Specifically, the inlet 111 of the liquid flow channel 110 is located on the upper side of the valve body 100 to allow liquid to flow in, and the outlet 112 of the liquid flow channel 110 is located on the lower side of the valve body 100 to allow liquid to flow out. The vibrating element 150 can be located inside or outside the valve body 100, as long as it is fitted onto the outside of the liquid flow channel 110. Preferably, such as Figure 2 The valve body 100 is provided with a mounting cavity 130, the liquid flow channel 110 passes through the mounting cavity 130, and the vibrating element 150 is placed in the mounting cavity 130. The vibrating element 150 is electrically controlled. At the same time, the air flow channel 120 can be filled with compressed gas that can atomize the liquid.

[0025] Please see again Figures 1 to 3In one embodiment of this utility model, the airflow channel 120 is disposed on the valve body 100. The airflow channel 120 includes an axial channel 122, the end of which is an air outlet 127. The axial channel 122 surrounds the liquid flow channel 110 and extends along the axial direction of the liquid flow channel 110. The outer diameter of the axial channel 122 gradually decreases in the direction toward the air outlet 127. That is, the airflow channel 120 and the liquid flow channel 110 are both integrated on the valve body 100, which makes the structure of the spray device 01 simpler and more compact. At the same time, by setting the outer diameter of the axial channel 122 to be gradually decreasing in the direction toward the air outlet 127, the gas sprayed from the air outlet 127 has a converging force. The liquid flowing from the liquid outlet 112 will first converge and gather under the converging force, and then quickly diffuse outward after gathering, becoming a spray. The function of gas concentration is twofold: to control and guide the liquid to the precise spraying direction; and to remove disorderly splashed liquid along the way, preventing it from splashing onto the liquid outlet of the nozzle and causing blockage.

[0026] Furthermore, the axial flow channel 122 also forms an air inlet 126 on the valve body 100, which can be connected to a compressed air source. It should be specifically noted that those skilled in the art should understand that, as Figure 2 and Figure 3 The axial flow channel 122 is arranged in a ring shape in the liquid flow channel 110. The axial flow channel 122 has an inner ring wall and an outer ring wall. The outer wall of the liquid flow channel 110 is the location of the inner ring wall of the axial flow channel 122. The radial dimension of the inner ring wall is the inner diameter of the axial flow channel 122, and the radial dimension of the outer ring wall is the outer diameter of the axial flow channel 122.

[0027] Furthermore, when a liquid flow channel 110, a gas flow channel 120, and a mounting cavity 130 are integrated on the valve body 100, the mounting cavity 130 and the gas flow channel 120 are sequentially and spaced apart on the valve body 100 in the direction from the liquid inlet 111 of the liquid flow channel 110 toward the liquid outlet 112 (i.e., the direction of liquid flow within the liquid flow channel 110).

[0028] In one embodiment of the present invention, the airflow channel 120 further includes a radial channel 121, which includes a first air chamber 124 and a second air chamber 125. The first air chamber 124 and the second air chamber 125 are connected through a vent 128. The first air chamber 124 is provided with an air inlet 126. The second air chamber 125 is connected to the end of the axial channel 122 away from the air outlet 127. The opening direction of the vent 128 is perpendicular to the air inlet direction of the air inlet 126. By adding a radial flow channel 121, the air source entering from the inlet 126 first flows in the radial flow channel 121 and then flows into the axial flow channel 122, so that it is finally ejected from the outlet 127. At the same time, the radial flow channel 121 is further divided into a first air chamber 124 and a second air chamber 125. The air intake direction of the inlet 126 of the first air chamber 124 is perpendicular to the opening direction of the vent 128 connecting the first air chamber 124 and the second air chamber 125. This ensures that the gas undergoes at least two direction changes for "rectification". Because the compressed gas from the external air source is full of disordered vortices and disturbances, and its speed, pressure and direction are not uniform, if it directly acts on the droplets, it will cause inaccurate spray position and uneven amount of sprayed droplets at different positions. Therefore, this setting is necessary. The specific functions are as follows: stabilizing the airflow speed and unifying the airflow direction; stabilizing the air pressure; and eliminating disordered vortices in the gas.

[0029] Furthermore, such as Figure 3 The radial flow channel 121 can be sequentially connected by an air inlet 126, a first air chamber 124, and a second air chamber 125. The first air chamber 124 is located on one side of the axial flow channel 122 and is spaced apart from the axial flow channel 122. The second air chamber 125 is located at the end of the axial flow channel 122 away from the air outlet 127 and communicates with the axial flow channel 122. The air inlet 126 extends radially on the outer peripheral wall of the valve body 100 and extends to penetrate the first air chamber 124. The first air chamber 124 and the second air chamber 125 are connected through a vent 128.

[0030] In one embodiment of this utility model, the second air chamber 125 is located above the first air chamber 124, and a partition plate 141 is provided between the first air chamber 124 and the second air chamber 125 to separate the upper and lower air chambers. The air inlet 126 is radially extended from the outer peripheral wall of the valve body 100 at the upper part of the first air chamber 124, and the air vent 128 is located on the partition plate 141 and is located at one end near the air inlet 126. Specifically, the upper and lower sides of the partition plate 141 can be respectively divided into the lower wall surface of the second air chamber 125 and the upper wall surface of the first air chamber 124. This allows gas to be radially injected into the first air chamber 124 from the air inlet 126. Under the resistance of the upper wall of the first air chamber 124 and the side wall opposite to the air inlet 126, the gas first flows downwards, then flows towards the side wall of the air inlet 126 under the resistance of the lower wall of the first air chamber 124, and then flows upwards under the resistance of the side wall of the air inlet 126, finally entering the upper second air chamber 125 through the vent 128. This allows the gas to change direction three times in the first air chamber 124, forming a circular flow path before entering the second air chamber 125, further "rectifying" the flow. Specifically, this has the following effects: stabilizing airflow velocity and direction; stabilizing air pressure; and eliminating disordered vortices in the gas. More specifically, the first air chamber 124 can be a square cavity, so the gas flow path in the first air chamber 124 is approximately a square circle.

[0031] More specifically, a vertical partition plate 142 is provided between the first air chamber 124 and the second air chamber 125 to separate the inner and outer air chambers. The vertical partition plate 142 extends vertically along the side wall of the first air chamber 124 opposite to the air inlet 126 toward the side facing away from the air outlet 127. The partition plate 141 is connected to the lower wall of the partition plate 142 away from the first air chamber 124 and extends horizontally toward the side wall of the air inlet 126. The end of the partition plate 141 away from the partition plate 142 is spaced apart from the side wall of the air inlet 126 to form a vent 128. The second air chamber 125 includes an ascending section 125a separated from the first air chamber 124 by the partition plate 141 and a descending section 125b separated from the first air chamber 124 by the partition plate 142. The end of the descending section 125b away from the ascending section 125a is connected to the axial flow channel 122. The gas enters the rising section 125a of the second gas chamber 125 from the vent 128, and then changes direction within the rising section 125a to flow horizontally towards the descending section 125b. It then changes direction again at the junction of the rising section 125a and the descending section 125b to flow downwards into the descending section 125b, ultimately being guided into the axial flow channel 122. This allows for further "rectification," specifically: stabilizing the airflow velocity and direction; stabilizing air pressure; and eliminating disordered vortices in the gas.

[0032] In one embodiment of this utility model, the portion of the liquid flow channel 110 located in the axial flow channel 122 is configured as a tapered flow channel section 113. The end of the tapered flow channel section 113 forms a liquid outlet 112, and the inner diameter of the tapered flow channel section 113 gradually decreases in the direction toward the liquid outlet 112. By configuring the section of the liquid flow channel 110 that forms the liquid outlet 112 as a tapered flow channel section 113, the liquid flowing out of the liquid outlet 112 can flow in a converging direction, so that the liquid is first gathered and concentrated under the converging force of the gas ejected from the gas outlet 127, and then rapidly diffuses outward after gathering, becoming a spray. The main function of the conical flow channel section 113 is to increase the gas velocity to the point where it can atomize droplets and guide the airflow direction to the direction where the liquid can be focused. When the fluid passes through a narrower and narrower channel, its velocity will increase as the total flow rate remains constant. After passing through this channel, the airflow that was originally rectified will be guided to the correct direction and will have a strong impact force, thereby enabling precise control of the liquid spraying position and dispersing the liquid into a uniform spray.

[0033] Specifically, the liquid and gas will focus at the same focal point, where the wind force reaches its maximum. The liquid will be cut into a large number of fine mist droplets (atomization) by the high-speed airflow blowing from its circumference. Then the airflow is evenly carried to the surrounding area and will fall precisely into a predetermined area, thereby achieving uniform spraying at a fixed position.

[0034] In one embodiment of this utility model, there are two radial flow channels 121, which are respectively arranged on opposite sides of the axial flow channel 122. Since the axial flow channel 122 is annular outside the liquid flow channel 110, and the air outlet 127 is arranged around the liquid outlet 112, in order to ensure the uniformity of air output from the air outlet 127, radial flow channels 121 can be provided on opposite sides of the axial flow channel 122, so as to supply air to the axial flow channel 122 from opposite sides respectively.

[0035] In one embodiment of this invention, the vibrating element 150 is a piezoelectric ceramic component. Piezoelectric ceramics, as materials capable of efficiently converting electrical energy into mechanical energy, utilize the inverse piezoelectric effect under energized conditions. They deform under the influence of an electric field, thus generating mechanical vibration. This process offers advantages such as high efficiency, rapid response, high precision, and high stability. Furthermore, when controlling the vibration of the piezoelectric ceramic component, a high-frequency current signal with a pre-defined frequency and waveform generated by a controller can be input to the positive and negative electrodes of the piezoelectric ceramic component. This generates an electric field at both ends of the electrodes that changes according to the set frequency and waveform, thereby driving the ceramic to vibrate at high frequency. This further suppresses sedimentation and aggregation in the liquid and ensures a uniform distribution of the substance. Simultaneously, the high-frequency vibration induces cavitation within the liquid flow channel, making it easier for the liquid to be subsequently atomized by gas. Of course, this invention is not limited to this; the vibrating element 150 can also be other suitable vibrators from the prior art.

[0036] See Figure 4 and Figure 5 In one embodiment of this utility model, the spray device 01 further includes a liquid storage tank 20 capable of storing liquid. The liquid storage tank 20 is connected to the liquid inlet 111, and a switching valve is provided between the liquid storage tank 20 and the spray valve 10. That is, by adding the liquid storage tank 20 and the switching valve, the automatic supply of liquid to the spray valve 10 can be achieved by controlling the opening of the switching valve.

[0037] In one embodiment of this invention, an ultrasonic generator 21 is provided inside the liquid storage tank 20. By adding the ultrasonic generator 21, the liquid inside the liquid storage tank 20 can be dispersed by controlling the ultrasonic generator 21. Specifically, the ultrasonic generator 21 is elongated and inserted into the liquid storage tank 20. It can convert electrical energy into ultrasonic waves and transmit them to the liquid. The liquid vibrates at high frequency due to the action of the ultrasonic waves, preventing a decrease in concentration caused by crystallization and precipitation over a long period, thereby ensuring the homogeneity of the solution.

[0038] In addition, see Figure 5This utility model also provides a salt spraying drying device, which includes a supporting device 02, a transfer device 03, a flipping device 04, and a spraying device 01 as described above. The supporting device 02 has a jig assembly that rotates circumferentially, and multiple product placement positions are arranged at intervals along the rotation direction on the jig assembly. The transfer device 03 is located on one side of the supporting device 02 and is equipped with the spraying device 01. The transfer device 03 can drive the spraying device 01 to spray salt onto the processed parts 05 on the product placement positions. The flipping device 04 is located on one side of the supporting device 02 and has a clamping part that can be flipped. The clamping part can clamp the processed parts 05 on the product placement positions and flip them over. Since the salt spraying drying device adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0039] Specifically, the jig assembly has multiple product placement positions for placing workpieces 05 to be salt-sprayed, allowing multiple workpieces 05 to be processed in a single loading. Simultaneously, the jig assembly rotates circumferentially, creating several workstations in the rotational direction. The spraying device 01 is mounted on the transfer device 03 for automatic salt spraying of workpieces 05 at a specific workstation. The addition of the flipping device 04 allows for the flipping of workpieces 05 at the corresponding workstation, enabling the spraying device 01 to perform salt spraying on the flipped side of workpiece 05 at the next workstation.

[0040] More specifically, the product placement positions are all designed to be heated. The fixture assembly has four product placement positions, spaced apart sequentially along the rotation direction. The side of the fixture assembly furthest from the flipping device 04 is the preheating station, and the side closer to the flipping device 04 is the flipping station. The other two opposite sides of the fixture assembly are the first and second salt spraying stations. The fixture assembly can rotate counter-clockwise. The workpiece 05 located on the product placement position can rotate sequentially from the preheating station to the first salt spraying station and then flip. The workpiece 05 is preheated at the preheating station, then rotated to the first salt spraying station. The transfer device 03 drives the salt spraying device to spray salt onto the upward-facing side of the workpiece 05 at the first salt spraying station. Next, it rotates to the flipping station, where the flipping device 04 flips the workpiece 05 over. Finally, it rotates to the second salt spraying station, where the transfer device 03 drives the salt spraying device to spray salt onto the upward-facing side of the workpiece 05. This achieves fully automated salt spraying of the workpiece 05, maximizing processing efficiency.

[0041] In one embodiment of this utility model, the supporting device 02 further includes a rotary drive component. The fixture assembly includes a supporting base plate 022, a heating plate 023, and positioning blocks 024. The rotary drive component is drivenly connected to the supporting base plate 022. Multiple mounting grooves are evenly spaced along the rotation direction on the upper side of the supporting base plate 022. A heating plate 023 is installed within each mounting groove, and positioning blocks 024 are provided on the heating plate 023 to enclose and form a product placement position. The addition of the heating plate 023 allows the workpiece 05 to be placed flat on the heating plate 023, ensuring uniform heating. The addition of the positioning blocks 024 ensures the accuracy of the placement of the workpiece 05. Specifically, there are two positioning blocks 024. The two positioning blocks 024 are positioned one-to-one with the two corner positions on the same side of the workpiece 05. Both positioning blocks 024 are L-shaped to stop different sides of the workpiece 05 at their respective corner positions.

[0042] In one embodiment of this utility model, the transfer device 03 includes a mounting frame 031, an X-axis drive mechanism 032, a Y-axis drive mechanism 033, and a Z-axis drive mechanism 034. The mounting frame 031 is erected on one side of the supporting device 02. The X-axis drive mechanism 032 is located at the upper end of the mounting frame 031. The Y-axis drive mechanism 033 is drivenly connected to the X-axis drive mechanism 032, and the Z-axis drive mechanism 034 is drivenly connected to the Y-axis drive mechanism 033. The spraying device 01 is mounted on the Z-axis drive mechanism 034, and the tilting device 04 is located on the mounting frame 031. The inclusion of the X-axis drive mechanism 032, Y-axis drive mechanism 033, and Z-axis drive mechanism 034 in the transfer device 03 allows for a sufficiently large adjustment range for the position of the spraying device 01. Furthermore, placing the tilting device 04 on the mounting frame 031 improves the overall integrity of the equipment.

[0043] Specifically, the flipping device 04 includes a slide rail base 041, a slider 042, a connecting plate 043, a sliding drive component 044, a flipping drive component 045, and a flipping robot 046. The slide rail base 041 and the sliding drive component 044 are both mounted on the mounting frame 031. The slider 042 is slidably connected to the slide rail base 041. The sliding drive component 044 is driven to connect with the slider 042 to drive the slider 042 to move closer to or away from the flipping station. The connecting plate 043 is connected to the slider 042. The flipping drive component 045 is located on the side of the connecting plate 043 facing the bearing device 02. The flipping robot 046 is driven to connect with the flipping drive component 045 to clamp the workpiece 05 under the drive of the flipping drive component 045 and drive the workpiece 05 to flip.

[0044] Furthermore, the driving components of the X-axis drive mechanism 032, Y-axis drive mechanism 033, and Z-axis drive mechanism 034, as well as the sliding drive component 044, are all lead screw motors. Two open sliding grooves are provided on each side of the guide rails of the X-axis drive mechanism 032, Y-axis drive mechanism 033, and Z-axis drive mechanism 034, respectively. Corresponding lead screw structures are provided within the guide rails. The X-axis drive mechanism 032 and Y-axis drive mechanism 033 share a first slider. Two first sliding parts, spaced apart and L-shaped, are provided on the lower side of the first slider. These two first sliding parts correspondingly slide from the opposite sides of the guide rail of the X-axis drive mechanism 032 through the corresponding open sliding grooves. The groove extends into the guide rail and is driven by the lead screw structure; the upper side of the second slider is provided with two second sliding parts that are relatively spaced apart and are both L-shaped. The two second sliding parts extend into the guide rail from the corresponding open grooves on the opposite sides of the guide rail of the Y-axis drive mechanism 033 and are driven by the lead screw structure; the Z-axis drive mechanism 034 is provided with a second slider for mounting the spray device. The side of the second slider away from the spray device is provided with two third sliding parts that are relatively spaced apart and are both L-shaped. The two third sliding parts extend into the guide rail from the corresponding open grooves on the opposite sides of the guide rail of the Z-axis drive mechanism 034 and are driven by the lead screw structure.
