Description

Technical Field

[0001] The utility model relates to the technical field of galvanized steel plate processing, in particular to a galvanized steel plate passivation liquid spraying device. Background Art

[0002] The galvanized steel plate passivation liquid spraying device is a processing equipment in the manufacture of galvanized steel plates. Its main function is to evenly apply a layer of passivation liquid on the surface of the galvanized steel plate to prevent the steel plate from generating "white rust" when placed in humid air for a long time. The equipment can ensure that the passivation liquid is evenly sprayed on the surface of the steel plate, thereby improving production efficiency. Moreover, through the recovery system, the passivation liquid can be recovered and utilized to the maximum extent, thereby reducing production costs.

[0003] In the existing galvanized steel plate passivation liquid spraying device, after the multiple groups of nozzles therein spray the galvanized steel plate, some of the passivation liquid remaining inside will fall onto the galvanized steel plate at the bottom due to gravity, and the nozzles that just started spraying in the subsequent spraying will also have the problem of uneven spraying. Therefore, we propose a galvanized steel plate passivation liquid spraying device. Utility Model Content

It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] The following describes a galvanized steel plate passivation liquid spraying device provided by some embodiments of the present invention in conjunction with the accompanying drawings. Example 1

[0024] Combine Figure 1-3 As shown, the utility model provides a galvanized steel plate passivation liquid spraying device, comprising: a sprayer 100, a spraying assembly 200, and a blocking assembly 300; the sprayer 100 includes a feed port 101 and a discharge port 102 at both ends thereof, a conveying roller 103 and a transmission roller 104 arranged and installed at the lower end and the upper end thereof; the spraying assembly 200 includes a spraying pipe 201 fixedly installed at the top of the sprayer 100, a plurality of nozzles 202 arranged and fixedly installed at the bottom of the spraying pipe 201, a pre-collection box 203 movably installed at the lower end of the nozzle 202, and a pre-collection box 203 in which the nozzle 202 is mounted. A collection chamber 204 is opened, a middle diverter strip 205 and a side diverter strip 206 are fixedly installed in the middle and on both sides of the collection chamber 204 respectively, and a bottom guide strip 207 is symmetrically fixedly installed on both sides of the lower part of the collection chamber 204. A connecting frame 208 is also fixedly installed at both ends of one side of the pre-collection box 203, and an electric push rod 209 is also fixedly installed on one side of the connecting frame 208. A sharp portion 210 is also provided on the upper part of one side of the pre-collection box 203, and a recovery hose 211 is also fixedly connected to one side of the pre-collection box 203. The electric push rods 209 are all fixed to the top of the inner end of the sprayer 100.

[0025] Specifically, the galvanized steel plate passivation liquid spraying device is a processing equipment in the manufacture of galvanized steel plates, and its main function is to evenly coat a layer of passivation liquid on the surface of the galvanized steel plate to prevent the steel plate from generating "white rust" when placed in humid air for a long time; the multiple groups of nozzles 202 in this sprayer 100 can also be pre-sprayed into the pre-collection box 203 at the bottom before spraying the galvanized steel plate, so that the pre-collection box 203 at the bottom can be removed after the nozzles 202 spray evenly, so as to ensure that the galvanized steel plate conveyed at the bottom has good uniformity during spraying, and the middle diverter strip 205, the side diverter strip 206 and the bottom guide strip 207 installed at the upper and lower ends of the pre-collection box 203 are mainly used The spray liquid in the pre-spraying of the nozzle 202 in the pre-collection box 203 is drained and blocked, so as to avoid splashing to the outer end of the nozzle 202 and dripping during spraying to cause unevenness. After the spraying of the galvanized steel plate is completed, the electric push rod 209 in the sprayer 100 will also drive the pre-collection box 203 to move it to the bottom of the multiple groups of nozzles 202, so as to collect the passivation liquid remaining in the nozzle 202 after dripping, so as to avoid dripping to the upper end of the galvanized steel plate after spraying and causing uneven spraying. The recovery hose 211 connected to one side of the pre-collection box 203 is mainly used for dripping collection in the pre-collection box 203 and recycling of passivation liquid collected in pre-spraying. Example 2

[0026] Combine Figure 3 As shown, on the basis of embodiment one, the blocking assembly 300 includes a baffle 301 movably installed at both ends of the middle part of the sprayer 100, a connecting rod 302 movably installed between one side of the baffle 301 and the outer wall of the pre-collection box 203, and a rotating seat 303 is rotatably connected and installed on the top of the baffle 301, and the rotating seat 303 is fixed to the inner end side wall of the sprayer 100.

[0027] Specifically, the baffles 301 on both sides of the pre-collection box 203 connected by the connecting rod 302 can also block the galvanized steel plate on the upper end of the conveying roller 103 through the baffles 301 vertically on both sides of the front end of the middle conveying roller 103 when the nozzle 202 is pre-spraying in the pre-collection box 203, so as to facilitate the positioning of the galvanized steel plate on the conveying roller 103 during the pre-spraying of the nozzle 202.

[0028] The working principle and use process of this utility model:

[0029] When spraying galvanized steel sheets, they are first put in through the feed port 101 on one side of the sprayer 100 and moved to the rear end of the baffles 301 on both sides of the sprayer 100. At this time, the multiple groups of nozzles 202 at the lower end of the spray pipe 201 are started. After the multiple groups of nozzles 202 are started, they will be pre-sprayed in the pre-collection box 203. At the same time, the middle diverter strips 205, side diverter strips 206 and bottom guide strips 207 at the upper and lower parts of the pre-collection box 203 can also divert and block the passivation liquid pre-sprayed at the bottom of the nozzle 202 to avoid splashing during the pre-spraying, and maintain uniform spraying of the multiple groups of nozzles 202. After that, the electric push rods 209 on both sides of the top of the sprayer 100 can be started to drive the pre-collection box 203 to move forward. After the pre-collection box 203 moves forward, the lower end of the baffle 301 will be pulled to rotate and lift through the connecting rods 302 on both sides, so that the galvanized steel sheet on the upper end of the conveying roller 103 can be conveyed after the nozzle 202 is evenly sprayed, so as to evenly spray the galvanized steel sheet. After the galvanized steel sheet is conveyed and sprayed, the electric push rods 209 will also push the pre-collection box 203 and the baffle 301 back to their original positions, thereby collecting the passivation liquid dripping from the bottom of the nozzle 202 and blocking the two sides of the front end of the middle conveying roller 103.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
