A high efficiency paint spray booth for collecting paint overspray

Abstract

This utility model discloses a high-efficiency spray booth for collecting sprayed paint mist, relating to the field of spray booth technology. It includes a vortex processing component, comprising a spray booth with a circulating water tank at the bottom and a vortex chamber containing a vortex plate. This utility model, by setting up the vortex processing component, enables the exhaust gas to undergo primary separation treatment through the centrifugal force generated by the vortex within the vortex chamber, combined with water flow. The exhaust gas, after most of the paint mist has been separated, enters a water vortex tank for secondary separation treatment. After entering the water vortex tank, the exhaust gas, through the sprayed water mist and the high-speed centrifugal force within the tank, separates the paint particles. The water mist then performs a secondary separation, thoroughly removing the paint mist from the exhaust gas. This secondary separation solves the problem of large amounts of paint mist carried during exhaust gas transportation, preventing excessive paint mist from being carried into the duct and accumulating there.

Description

Technical Field

[0001] This utility model relates to the field of spray painting station technology, and in particular to a spray painting station that efficiently collects sprayed paint mist. Background Technology

[0002] A spray booth is an industrial spraying equipment mainly used for purifying paint mist and treating exhaust gas during spray painting operations. It provides a closed or semi-closed working environment for operation. Its function is to capture paint mist and exhaust gas generated during spray painting through water circulation or filtration systems, thereby effectively reducing environmental pollution, protecting the health of operators, and improving the quality of spray painting. The existing technology involves cleaning the paint mist after spraying the workpiece through a water curtain washing device. After cleaning, the remaining paint mist is drawn into the exhaust gas duct by a fan and then enters the exhaust gas treatment box for further treatment. During the transportation process, the paint mist will accumulate in the fan and duct.

[0003] The ability to collect paint mist through water washing is crucial in the painting process. Current technologies do not collect enough paint mist, resulting in a significant amount of paint mist being carried into the air duct and accumulating there. This can affect the effectiveness of subsequent maintenance and treatment, as well as the exhaust gas treatment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a spray booth for efficiently collecting paint mist.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency paint spraying station for collecting paint mist includes a vortex treatment component. The vortex treatment component includes the spraying station itself, a circulating water tank at the bottom of the spraying station, a vortex chamber within the spraying station containing a vortex plate with an opening connected to the circulating water tank, a baffle plate inclinedly positioned within the vortex chamber, the position and size of the baffle plate matching the vortex plate, a water supply tank within the spraying station with an opening at the bottom connected to the vortex chamber, several sets of water swirl tanks within the spraying station with their bottoms connected to the vortex chamber, several sets of swirl plates within the water swirl tanks, an air outlet at the top of the spraying station connected to the water swirl tanks, an observation window connected to one side of each water swirl tank, an adsorption component for further adsorbing paint mist and an auxiliary spraying component on one side of the spraying station, and a detachable observation window on one side of each water swirl tank.

[0007] As a further embodiment of this utility model: the adsorption component includes a paint mist filter layer, and several sets of the paint mist filter layer are arranged in parallel within the spray booth. The position of the paint mist filter layer is adapted to the outlet end of the water swirl tank. The paint mist filter layer is filled with cleaning balls, and the cleaning balls have honeycomb-shaped openings.

[0008] As a further embodiment of this utility model: the spraying assembly includes a water pump, which is located on one side of the spray booth. One end of the water pump is connected to a circulating water tank. An upper spraying frame is provided on the inner wall of the spray booth, and the position of the upper spraying frame is adapted to the water vortex tank. A lower spraying frame is also provided on the inner wall of the spray booth, and the position of the lower spraying frame is adapted to the vortex chamber.

[0009] As a further improvement of this utility model: the side wall of the vortex plate is provided with an arc surface, and the shape of the arc surface is snail-shaped.

[0010] As a further improvement of this utility model: the spray painting station is rotatably equipped with a separation plate, the size and position of which are adapted to the vortex plate.

[0011] As a further improvement of this utility model: the bottom of the separation plate is provided with several sets of slots, and the slots are serrated in shape.

[0012] As a further improvement of this utility model: the circulating water tank is provided with a set of partitions, the size of which is adapted to the circulating water tank.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up a vortex treatment component, the centrifugal force generated by the vortex in the vortex chamber, combined with the water flow, can complete the primary separation treatment of the exhaust gas. The exhaust gas after most of the paint mist has been separated can enter the water vortex tank for secondary separation treatment through the vortex chamber. After the exhaust gas enters the water vortex tank, the paint particles can be separated by the sprayed water mist and the high-speed centrifugal force in the water vortex tank. After separation, secondary separation can be carried out by water mist, which can completely and thoroughly remove the paint mist from the exhaust gas. The secondary separation of paint mist can solve the problem of a large amount of paint mist being carried in the exhaust gas during transportation, avoiding the situation where a lot of paint mist is brought into the air duct and accumulates in the air duct during transportation, thus avoiding affecting the effect of subsequent maintenance and treatment and the effect of exhaust gas treatment.

[0015] 2. By setting up an adsorption component, the exhaust gas can be further treated after the secondary separation of paint mist. The cleaning ball can adsorb the last remaining tiny paint mist in the exhaust gas, thereby avoiding the presence of paint mist residue in the exhaust gas. It can complete the collection of paint mist in a comprehensive and efficient manner, making the subsequent exhaust gas transportation and treatment more convenient.

[0016] 3. By setting up a spray assembly, water can be supplied to the water vortex tank, thus enabling normal secondary separation of paint mist. Water sprayed from the lower spray frame can also rinse the vortex chamber, effectively cleaning away residual paint mist inside the vortex chamber and increasing the paint mist separation effect.

[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Example 1

[0026] A spray booth for efficiently collecting paint mist, such as Figure 1-5As shown, the system includes a vortex treatment assembly, comprising a spray booth 1, a circulating water tank 3 at the bottom of the spray booth 1, a vortex chamber 16, a vortex plate 4 inside the vortex chamber 16, the opening of the vortex plate 4 communicating with the circulating water tank 3, a baffle plate 12 inclinedly arranged inside the vortex chamber 16, the position and size of the baffle plate 12 being adapted to the vortex plate 4, and a water supply tank 13 inside the spray booth 1, the opening at the bottom of the water supply tank 13 being connected to the vortex chamber. 16. The spray booth 1 is equipped with several sets of water swirl tanks 10. The bottom of the water swirl tank 10 is connected to the vortex chamber 16. Several sets of swirl plates 11 are installed inside the water swirl tank 10. The top of the spray booth 1 is equipped with an air outlet 6, which is connected to the water swirl tank 10. An observation window 7 is connected to one side of the water swirl tank 10. An adsorption component for further adsorbing paint mist and an auxiliary spraying component are installed on one side of the spray booth 1. An observation window 7 is detachably installed on one side of the water swirl tank 10.

[0027] In use, the product to be painted can be hung in the spray painting station 1, and painted using a handheld spray gun. After painting, the suspended product can be removed for further processing. A fan is connected to one side of the spray painting station 1, which can supply high-pressure gas into the spray painting station 1. Water can be added through the water supply tank 13, and the water flow can be added into the vortex chamber 16 through the water supply tank 13. The baffle plate 12 can guide the flow. When painting, the air containing paint mist will enter the vortex chamber 16. With the input high-pressure gas, the air containing paint mist will rotate back and forth in the vortex chamber 16 and come into full contact with the added water flow, so that the paint mist is separated from the air and absorbed by the water. The high-pressure gas and water flow can generate a certain centrifugal force. Under the action of centrifugal force, the water containing paint mist will be thrown to the vortex plate 4, and then flow to the circulating water tank 3 for storage. The gas that has separated most of the paint mist by centrifugal force will be treated again through the water vortex tank 10. The spraying component can then spray the water vortex tank 10. Water is added, and the spray assembly can clean the residual paint mist in the vortex chamber 16 and vortex plate 4. The gas can enter the water vortex tank 10 through the vortex chamber 16. Secondary separation can be performed in the water vortex tank 10. After the air containing paint mist enters the water vortex tank 10, the exhaust gas forms a water vortex with the water vapor in the water vortex tank 10 in conjunction with the vortex plate 11. By adding clean water into the water vortex tank 10, the paint mist in the air can be fully absorbed, which can form a secondary separation effect of paint mist to avoid paint mist residue in the exhaust gas. The vortex plate 11 can generate high-speed centrifugal force in the water vortex tank 10. The high-speed centrifugal force can remove the water flow with paint mist adsorbed. The water flow with paint mist adsorbed can be sent into the vortex chamber 16 and discharged into the circulating water tank 3 through the vortex plate 4 for sedimentation. The paint in the circulating water tank 3 can be regularly removed, thereby maintaining the efficient operation of the exhaust gas treatment. The water vortex tank 10 is convenient for maintenance. After separation, the exhaust gas can be transported through the air outlet 6 by connecting to an exhaust fan.

[0028] The adsorption component includes a paint mist filter layer 9, which is provided in several groups and is arranged in parallel in the spray booth 1. The position of the paint mist filter layer 9 is adapted to the outlet end of the water swirl tank 10. The paint mist filter layer 9 is filled with cleaning balls 8, which have honeycomb-shaped openings.

[0029] When in use, the cleaning balls 8 filled in the paint mist filter layer 9, together with their honeycomb-shaped openings, can further adsorb and filter the exhaust gas discharged from the water swirl tank 10. The cleaning balls 8 can adsorb the last remaining tiny paint mist in the exhaust gas, thereby avoiding paint mist residue in the exhaust gas. After a certain period of use, the cleaning balls 8 can be disassembled and cleaned, and can be reused after cleaning.

[0030] The spraying assembly includes a water pump 2, which is located on one side of the spray booth 1. One end of the water pump 2 is connected to the circulating water tank 3. An upper spraying frame 14 is provided on the inner wall of the spray booth 1. The position of the upper spraying frame 14 is adapted to the water vortex tank 10. A lower spraying frame 15 is also provided on the inner wall of the spray booth 1. The position of the lower spraying frame 15 is adapted to the vortex chamber 16.

[0031] In use, the upper spray frame 14 and the lower spray frame 15 can be connected to the water pump 2 through pipes. The water pump 2 can be started to draw water from the circulating water tank 3. After drawing, the water can be delivered to the upper spray frame 14 and the lower spray frame 15. After being delivered to the upper spray frame 14 and the lower spray frame 15, it can be sprayed out through its nozzles. The nozzle of the upper spray frame 14 is set facing the internal space of the vortex chamber 16. The water flow sprayed by the lower spray frame 15 can rinse the vortex chamber 16, thereby cleaning away the paint mist remaining in the vortex chamber 16 and on the vortex plate 4. The nozzle of the upper spray frame 14 leads to the water vortex tank 10. The water flow sprayed by the upper spray frame 14 into the water vortex tank 10 can provide the water source required for the formation of the water vortex in the water vortex tank 10, thereby realizing the secondary separation of paint particles.

[0032] To ensure the effectiveness of paint mist separation, such as Figure 5 As shown, the sidewalls of the vortex plate 4 are provided with arc surfaces, and the shape of the arc surfaces is snail-shaped;

[0033] When in use, the spiral arc surface designed on the four side walls of the vortex plate can effectively increase the centrifugal force, thereby effectively ensuring the separation effect of paint mist.

[0034] To regulate airflow speed, such as Figure 1 , 5 As shown, the paint spraying station 1 is rotatably mounted with a separation plate 5, the size and position of which are adapted to the vortex plate 4;

[0035] In use, the angle of the separator plate 5 can be adjusted by rotating it. Adjusting the angle can change the opening size of the vortex plate 4, thereby adjusting the airflow speed. It can be adjusted to suit the needs.

[0036] In order to disperse and separate the paint mist during separation, such as Figure 1 , 5 As shown, the bottom of the separation plate 5 is provided with several sets of slots, and the slots are serrated in shape.

[0037] During use, the serrated slots at the bottom of the separation plate 5 can cut and tear the water flow when the high-speed airflow passes through. Compared with a smooth design, it can produce more water droplets with smaller particle size and more uniform distribution. These tiny water droplets have a larger total surface area, which allows them to collide and adsorb with paint mist particles more fully and efficiently, thus more thoroughly breaking down and separating the paint mist and effectively increasing the separation effect of the paint mist.

[0038] Example 2

[0039] To separate the water flow, refer to Figure 1-5 A spray booth for efficiently collecting spray paint mist. This embodiment makes the following improvements compared to embodiment 1: A set of partitions is provided inside the circulating water tank 3, and the size of the partitions is adapted to the circulating water tank 3.

[0040] In use, the circulating water tank 3 can be divided into a side water tank and a rear water tank by a partition. The rear water tank is used to receive and initially settle the wastewater flowing back from the vortex paint mist spraying station 1. The water tank is used to store the settled clean water and supply it to each spraying system through the water pump 2.
