[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] like Figure 1-4 As shown, this utility model provides a technical solution: a fine powder recovery device for a spray tower, including a support component 1, and a fine powder recovery component 2 fixedly installed on the top of the support component 1. The supporting component 1 includes a mounting base plate 101. Vertical plates 102 are fixedly mounted on both sides of the top surface of the mounting base plate 101 by welding. Sliding grooves are formed on opposite sides of each vertical plate 102. The lifting plate 103 is slidably mounted in the two sliding grooves on both sides, achieving a sliding connection between the lifting plate 103 and the two vertical plates 102. A stop 104 is bolted to the center of the bottom surface of the lifting plate 103, and a push-button switch 105 is bolted to the center of the top surface of the mounting base plate 101. The stop 104 is located directly above the push-button switch 105. The push-button switch 105 can be connected to an external alarm device (such as an alarm, indicator light, etc.) via a wire. Two mounting blocks 106 are bolted to both sides of the top surface of the mounting base plate 101. A round shaft 107 is welded between the two mounting blocks 106 on the same side. Sliding sliders 108 are slidably fitted onto both ends of the shafts of the two round shafts 107. The bottom surface of the sliding sliders 108 contacts the top surface of the mounting base plate 101, and the sliding sliders 108 can slide on the top surface of the mounting base plate 101. Springs 109 are fitted onto both ends of the shafts of the round shafts 107, and the two ends of the springs 109 are fixedly connected to the outer walls of the sliding sliders 108 and the mounting blocks 106 respectively by welding. The top surfaces of the two sliding blocks 108 are fixedly mounted with a first rotating seat 110 by bolts. The top surfaces of the two first rotating seats 110 on the same side are rotatably mounted with a transmission inclined rod 111 by a pin. The top ends of the two transmission inclined rods 111 are rotatably mounted with a second rotating seat 112 by a pin. The two second rotating seats 112 are fixedly mounted on both sides of the bottom surface of the lifting plate 103 by bolts. The fine powder recovery assembly 2 includes a recovery box 201, which is fixedly installed on the top surface of the lifting plate 103 by bolts. The recovery inlet pipe 202 is integrally formed on the rear part of the top surface of the recovery box 201. The recovery inlet pipe 202 can be connected to the fine powder outlet of the spray tower through a flange. The recycling bin 201 has a recycling chamber 203. An inclined plate 204 is fixedly installed on the bottom surface of the recycling chamber 203 by welding. The inclination angle of the inclined plate 204 can be set according to actual needs, generally 30° to 60°, so that fine powder can be better aggregated. The top front of the recycling bin 201 has a slot 205, into which a sealing plate 206 is movably inserted. The sealing plate 206 can be made of stainless steel, which has good wear resistance and sealing performance. A first magnetic plate 207 is glued to the bottom surface of the sealing plate 206, and a second magnetic plate 208 is glued to the bottom surface of the slot 205. The first magnetic plate 207 and the second magnetic plate 208 are arranged opposite each other with opposite poles attracting each other. A handle 209 is fixedly installed on the top surface of the sealing plate 206 by welding. The outer wall of the handle 209 can be covered with a rubber sleeve to increase the comfort of the staff when holding it, and at the same time play a role in preventing slipping. The working principle of this invention is as follows: When using the fine powder recovery device for the spray tower, the recovery inlet pipe 202 is first connected to the fine powder outlet of the spray tower via a hose. The fine powder generated by the spray tower enters the recovery chamber 203 of the recovery box 201 through the recovery inlet pipe 202. During the fine powder recovery process, due to the mutual attraction between the opposite poles of the first magnetic plate 207 and the second magnetic plate 208, the sealing plate 206 and the recovery box 201 have good sealing performance, which can effectively prevent the fine powder from leaking from the slot 205. As the amount of fine powder in the recovery chamber 203 increases, the overall weight of the recovery box 201 gradually increases, and the lifting plate 103 gradually descends under the action of gravity. The descent of the lifting plate 103 causes the push-button 104 to gradually approach the button switch 105. When the amount of fine powder in the recovery chamber 203 reaches the set value, the push-button 104 presses the button switch 105, which triggers the external alarm device to sound an alarm, reminding the staff to clean up the fine powder in time.

[0014] After receiving the alarm, the staff closes the fine powder outlet of the spray tower and then removes the sealing plate 206 from the slot 205 using the handle 209. Since the bottom surface of the recovery chamber 203 is provided with an inclined plate 204, the fine powder gathers to one side of the recovery chamber 203 under its own gravity, and the staff can easily clean out the fine powder. After the fine powder is cleaned, the overall weight of the recycling box 201 is reduced, and the sliding block 108 returns to its initial position under the elastic force of the spring 109. The movement of the sliding block 108 drives the transmission rod 111 to rotate, which in turn pushes the lifting plate 103 to rise. The stop 104 separates from the button switch 105, the alarm device stops alarming, and the device can continue to carry out the fine powder recycling work.

[0015] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
