Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, specifically a high-efficiency circulating air spray booth structure suitable for customized woodwork. Background Technology

[0002] A furniture spray booth, also known as a furniture baking booth, is a specialized piece of equipment used for spraying and drying furniture surfaces. This equipment reduces paint mist pollution through filtered airflow within a closed space, solving the problems of dust mixing, paint waste, and environmental pollution associated with traditional open-air spray painting. It mainly includes an air supply and filtration system, a paint mist treatment device, and a heat energy conversion device.

[0003] Spray booths use circulating fans to drive internal air circulation in order to reduce paint mist pollution. Existing circulating fans are integrated structures, and all of them must be turned on during operation. When the shape and size of the workpieces to be painted (such as custom woodwork) vary greatly, different areas require different air volumes. The integrated fans cannot adjust as needed, resulting in a large amount of air circulating in unnecessary areas, causing significant energy waste. At the moment when the painting is completed and the door is opened to remove the workpiece, a large amount of paint mist accumulated inside the spray booth will overflow, causing air pollution in the external working environment and endangering the health of workers.

[0004] The purpose of this invention is to provide a high-efficiency circulating air spray booth structure suitable for customized woodwork, so as to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0029] 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.

[0030] Example 1:

[0031] Please see Figure 1-4 A high-efficiency circulating air spray booth structure suitable for custom woodwork, comprising:

[0032] The room 1 has several installation ports 2 fixedly opened at the top of the room 1, several connection ports 3 are provided at the lower part of the interior of the room 1, an exhaust base 5 is fixedly installed at the bottom of the room 1, an exhaust fan 6 is provided at the front end of the exhaust base 5, the air inlet of the exhaust fan 6 is connected to the top of the exhaust base 5, an exhaust pipe 7 is provided at the top of the exhaust fan 6, and the bottom end of the exhaust pipe 7 is connected to the air outlet of the exhaust fan 6.

[0033] A filter mechanism 4 is installed inside the connection port 3;

[0034] The filter mechanism 4 includes a first grille 41, which is disposed inside the connection port 3, and the first grille 41 is filled with filter cotton 42.

[0035] A door frame 8 is provided on one side of the building 1, and a ramp 9 is provided on the left side of the door frame 8. The left side of the door frame 8 is aligned with the top of the inclined ramp 9. A slot 10 is provided inside the door frame 8, and an air curtain component 11 is provided on the top of the door frame 8.

[0036] The air curtain wall assembly 11 includes an air pump 111, which is located at the upper end of the slot 10. The lower end of the air pump 111 is provided with a first air duct 112 that is inclined to the left, and a second air duct 113 that is inclined to the right is provided on one side of the first air duct 112.

[0037] The first air duct 112 and the second air duct 113 are inserted through the slot 10 and installed on the inside of the door frame 8.

[0038] In this embodiment, when the wooden structure is pulled out, the door of room 1 opens accordingly. At this time, the air curtain wall assembly 11 installed in the slot 10 at the upper end of the door frame 8 is activated, and the internal air pump 111 is started. An object sensor (model E3Z-D61) detects an object, and the air pump 111 discharges gas downwards through two independent air ducts. The first air duct 112 is inclined outwards, blowing the airflow to the outside of room 1, and the second air duct 113 is inclined inwards, blowing the airflow to the inside of room 1. These two airflows in opposite directions converge at the doorway to form an air curtain barrier. This air curtain effectively isolates the air outside room 1 from the paint mist that may drift inside, preventing the paint mist from leaking out when the door is opened.

[0039] Example 2:

[0040] Please see Figure 5-6 This embodiment provides a technical solution based on Embodiment 1:

[0041] Air intake assembly 12 is located above the top of the chamber 1 and is used to input gas into the top of the chamber 1.

[0042] Side air outlet assembly 14 is disposed on both sides of the inner wall of the room 1 and is used to deliver air to both sides of the interior of the room 1.

[0043] The air intake assembly 12 includes a connecting pipe 121, which is installed in two air boxes 122. Air boxes 122 are provided on both sides of the connecting pipe 121, and an air box 122 is provided inside the mounting port 2.

[0044] The front end of the air box 122 is provided with a conveying pipe 123, and an independent valve 124 is provided on the outside of the conveying pipe 123. The front end of the conveying pipe 123 is provided with a central pipe 125. The top end of the conveying pipe 123 is centrally connected to an L-shaped central pipe 125. A blower 126 is provided at the bottom of one side of the central pipe 125. Two input pipes 127 are provided on the front side of the blower 126.

[0045] A second grille 13 is provided on the outer side of the side air outlet component 14, and the second grille 13 is fixedly installed on both sides inside the room body 1.

[0046] The side air outlet assembly 14 includes a side air duct 141, which is installed on the inner wall of the room 1. Several outlets 142 are opened at the upper end of the side air duct 141. Rotating rods 143 are rotatably connected to the left and right sides of the side air duct 141. An air supply pipe 144 is fixedly installed at the rear end of the side air duct 141, and the air supply pipe 144 is connected to the central pipe 125 in the air inlet assembly 12.

[0047] In this embodiment, when painting the woodwork, a camera inside the enclosure 1 captures the dimensions of the woodwork. Based on the identified dimensions, the controller activates the corresponding blower 126. The blower 126 draws in outside air through its internal fan. The outside air enters the housing via the input pipe 127 installed at the front end of the blower 126. The top of the blower 126 is connected to a central pipe 125 for gathering and delivering airflow. Based on the dimensions of the woodwork, the controller opens the corresponding independent valve 124. The airflow enters the corresponding delivery pipe 123 through the opened valve 124, and the delivery pipe 123 delivers the airflow to the corresponding... The bellows 122 ultimately inputs the adjusted airflow into the chamber 1 for use. To improve the uniformity of airflow distribution inside the chamber 1, side air outlet components 14 are added to both sides inside. The internal side air duct 141 is connected to the output end central pipe 125 of the blower 126 through the air supply pipe 144 to obtain airflow. The airflow is delivered to the side air duct 141 through the air supply pipe 144 and finally discharged from the outlet 142 on the side air duct 141. Rotating rods 143 are installed on both sides of the side air duct 141. The rotating rods 143 are connected to the gear set. This mechanism facilitates the subsequent adjustment of the blowing angle of the side air duct 141 as needed.

[0048] The working principle of this utility model is as follows: The woodwork is pushed into the room 1 through the ramp 9 set in the door frame 8. The door is closed, and preparation for painting is underway. The camera inside the room 1 captures the image of the woodwork, intelligently identifies its size, and starts the corresponding blower 126 according to the size of the woodwork. The blower 126 draws in external air through the input pipe 127. The airflow is delivered to the delivery pipe 123 through the central pipe 125. The corresponding independent valve 124 on the delivery pipe 123 is opened to control the airflow into the air box 122. The two air boxes 122 are connected by a connecting pipe 121. The air box 122 delivers air evenly into the room 1 through the installation port 2, improving the uniformity of airflow inside the room 1. Part of the airflow is diverted from the central pipe 125 at the output end of the blower 126 to the air supply pipe 144. The air supply pipe 144 is connected to the side air pipes 141 on both sides of the room 1. The gas passes through... The side air duct 141 discharges through its outlet 142. Rotating rods 143 are installed on both sides of the side air duct 141. The linkage gear set supports subsequent adjustment of the blowing angle of the side air duct 141 as needed. Air containing paint mist enters the exhaust base 5 through the lower end connection port 3 of the chamber 1. The airflow passes through the filter mechanism 4 (first grille 41, filter cotton 42) inside the connection port 3 in sequence. The filter cotton 42 adsorbs paint mist particles. The exhaust fan 6 starts and discharges the purified air through the exhaust pipe 7. When the woodwork is pulled out, the object sensor detects the door opening action. The air pump 111 at the upper end slot 10 of the door frame 8 starts. The air pump 111 sprays airflow downward through the double air duct. The first air duct 112 is tilted outward to block the influx of external air. The second air duct 113 is tilted inward to block the escape of internal paint mist. The two airflows converge to form an isolation air curtain to ensure that paint mist leaks out when the door is opened.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
