Description

Technical Field

[0001] The present application relates to the technical field of electrostatic spraying equipment, and in particular to an electrostatic spraying powder booth that facilitates dust recovery. Background Art

[0002] Electrostatic spraying is a spraying method that has been widely used in recent years. Through electrostatic adsorption, powdery coatings can be more evenly adhered to the surface of workpieces, and it can better adapt to the surface coating of some irregular workpieces.

In existing solutions, a powder booth made of some baffles and covers is used to block the powder, or water is used to wash the powder on the surface of the equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the present application in detail with reference to the accompanying drawings.

[0023] To more clearly understand the technical solutions presented in the embodiments of the present application, first, the working principle of an existing electrostatic spraying powder booth that facilitates dust recovery will be introduced.

[0024] There is an existing electrostatic spraying powder booth for dust recovery, which is welded into a box shape with iron sheets, and liquid pipes are erected on the four walls of the box. As a result, the sprayed powder can fall on the liquid, and the liquid can carry away the dust. Then, through processes such as precipitation, drying, and pulverization, the reuse of raw materials can be achieved, and the purpose of dust recovery is realized, reducing the application cost. However, during the existing operation process, some dust is in a floating state and takes a certain amount of time to fall from spraying to landing. There is still a phenomenon of dust overflow in the form of liquid recovery. Therefore, this dust recovery equipment needs to be improved to solve these problems.

[0025] Please refer to Figure 1 and Figure 4 , which discloses an electrostatic spraying powder booth that facilitates dust recovery according to an embodiment of the present application, including a box body 1, a diversion inclined plate 2, a water spraying branch pipe 3, a water supply main pipe 4, a collection base 5, a liquid storage tank 6, a diversion pipe 7, a dust filtering mechanism 8, an air extraction pipe 9, an exhaust fan 19, and a control switch 18. The upper end and the front side of the box body 1 are open. The diversion inclined plate 2 is fixedly connected to the inner side of the middle and lower position of the box body 1. The lower end of the diversion inclined plate 2 slopes downward, and a gap is provided in the middle of the lowest end of the diversion inclined plate 2. The water spraying branch pipes 3 are equidistantly and fixedly connected to the middle of the box body 1. The water supply main pipe 4 is respectively connected to the ends of the water spraying branch pipes 3 in a penetrating manner. The collection base 5 is fitted and connected to the lower surface at the gap of the diversion inclined plate 2. The liquid storage tank 6 is fixedly connected to the bottom inner wall on one side of the box body 1. One end of the diversion pipe 7 is connected to the bottom of one end of the collection base 5 in a penetrating manner, and the other end of the diversion pipe 7 is connected to the upper end of the liquid storage tank 6 in a penetrating manner. The dust filtering mechanism 8 is fixedly connected to the bottom inner wall on the side of the box body 1 away from the liquid storage tank 6. One end of the air extraction pipe 9 is connected to the upper part of the end of the collection base 5 in a penetrating manner, and the other end of the air extraction pipe 9 is bent upward and connected to the inlet end of the dust filtering mechanism 8 in a penetrating manner. The inlet end of the exhaust fan 19 is connected to the outlet of the dust filtering mechanism 8 in a penetrating manner. The control switch 18 is fixedly connected to the surface on one side of the box body 1. The input end of the control switch 18 is electrically connected to the output end of an external power supply, and the output end of the control switch 18 is electrically connected to the input end of the exhaust fan 19.

[0026] Specifically, the provided box body 1 provides support and connection for the carrier. The provided diversion inclined plate 2 enables the water flow to converge towards the middle and be discharged through the gap in the middle of the diversion inclined plate 2. The provided spray branch pipe 3 is provided with downward spray holes, which can disperse the pressure water source supplied by the main water supply pipe 4, and then evenly spray it on the surface of the diversion inclined plate 2 and the corresponding box body 1, so that the liquid carries the spraying particles and is discharged downward. The upper end of the provided collection base 5 is provided with an opening, which can be connected in cooperation with the gap at the lower surface of the diversion inclined plate 2, so that the liquid can completely enter the collection base 5. A rectangular diversion pipe 7 is arranged at the bottom of the collection base 5, which can enable the mixture of liquid and dust to fully flow into the liquid storage tank 6. The area of the liquid storage tank 6 is relatively large, so that the liquid can be statically placed inside. After a short static placement, the particulate matter can sink to the bottom, completing the process of dust collection, and avoiding a large amount of dust from adhering to the inner wall of the box body 1. The provided exhaust fan 19 can extract the air with floating dust inside the box body 1 downward, so that the gas enters the dust filtering mechanism 8 through the air extraction pipe 9. In the collection base 5, gas and liquid can enter simultaneously. Then the liquid flows downward, and the dry dust carried by the gas enters the dust filtering mechanism 8 after bending upward at the position of the air extraction pipe 9, effectively avoiding the entry of moisture. The dust filtering mechanism 8 is provided with components such as filter elements, which can realize the filtration of dust and achieve collection under dry conditions. It cooperates with the wet collection form of the liquid, and the two cooperate with each other to achieve the effect of being able to clean the adhered dust and recycle the dry dust.

The filter paper 82 is connected in cooperation with the inner wall of the pipe body 81. The dust filtering bag 83 is connected in cooperation with the corresponding pipe body 81 inside the filter paper 82. The air inlet of the dust filtering bag 83 is connected in a penetrating manner to the end of the outlet of the air extraction pipe 9.

[0028] Specifically, the provided pipe body 81 and the end cover 84 cooperate with each other to form a sealed cavity, and through holes are respectively arranged at the middle positions of both ends. When the gas carrying dust is pumped in through the exhaust fan 19, the dust-carrying gas can first enter the dust filtering bag 83. Effective filtration of particulate matter can be achieved at the dust filtering bag 83. Then, when the gas passes through the filter paper 82 again, secondary filtration can be achieved. The two can achieve the collection of dry dust particles. After the board is cleaned out, it can be directly utilized, realizing the rapid recycling of part of the dust, and having good practicability.
