The mechanical structure and the principle of the paint from the inlet pipe through the spray plate and finally out of the spray pipe are prior art, and therefore the internal switch of the spray pipe and the internal structure of the spray plate are not described in detail here.
The four exhaust pipes are respectively distributed at four corners of the adsorption cover, an air suction ring is coaxially arranged outside a sleeve in the adsorption cover, four communicating pipes are connected above the air suction ring, each communicating pipe is connected with the exhaust pipe, the inside of the air suction ring is of a hollow structure, air suction ports are uniformly distributed on the bottom surface of the air suction ring along the circumferential direction, a conical flow expansion cover is connected at the air suction ports, filter paper covers the bottom surface of the flow expansion cover, a plurality of mesh belts distributed in concentric circles are arranged on the filter paper, and an inverted cone-shaped flow gathering cylinder is connected below the flow expansion cover; generally, when the air in the adsorption hood is extracted by the extraction tube, not only harmful volatile gas in the air is removed, but also particle molecules dispersed in the air are removed, but the particle molecules are easy to adhere to the adsorption pipeline, so that a great number of coating molecules are adsorbed on the inner wall of the extraction tube over time, and the extraction tube cannot work normally any more; according to the invention, the suction ring is arranged in the adsorption cover, and the suction ports are uniformly distributed on the bottom surface of the suction ring along the circumferential direction, so that the whole cross-sectional area range in the adsorption cover is covered under the suction effect, and the adsorption efficiency and effect are improved; the air suction port is connected with a cone-shaped flow expansion cover, the bottom surface of the flow expansion cover is covered with filter paper, a plurality of mesh belts which are distributed in a concentric circle are arranged on the filter paper, an inverted cone-shaped flow gathering cylinder is connected below the flow expansion cover, air enters the flow gathering cylinder along the bottom opening of the flow gathering cylinder under the suction action of an air suction device connected outside the air suction pipe, then the air passes through the filter paper and then enters the air suction port through the flow expansion cover to be sucked out, wherein the filter paper is soaked with liquid capable of adsorbing certain harmful gases, and the size of the filter holes of the filter paper can be selected according to actual needs; when air is sucked from the bottom of the flow gathering cylinder, the air is subjected to flow gathering at the bottom of the flow gathering cylinder, then flow spreading during upward movement is carried out, finally the air passes through the filter paper and enters the flow spreading cover to be gathered, the flow gathering cylinder is arranged to increase the suction force between the air and the bottom of the flow gathering cylinder, the smaller the opening is, the larger the generated suction force is, the adsorption capacity on the air is improved, the kinetic energy of molecules in the air is increased, after the air passes through the bottom of the flow gathering cylinder and enters the flow gathering cylinder, the larger the diameter of the flow gathering cylinder is, the more the air has more movement space, so that the particles in the air are fully moved and diffused, when the air passes through the filter paper, the particulate matters in the air are adhered and adsorbed on the filter paper, and meanwhile, harmful gases in the air can also adsorb a part of the particles, so that the paint particle molecules in the air are removed, and the accumulation of the particulate matters on the inner walls of the air suction ring, only the filter paper needs to be replaced, and the exhaust tube does not need to be replaced, so that the maintenance cost is reduced; the filter paper is provided with a plurality of mesh belts distributed in concentric circles, so that gas can smoothly pass through the filter paper, the sizes of meshes in the mesh belts can be set according to actual needs, then air enters the flow expansion cover, and the bottom size of the flow expansion cover is larger than the top size, namely the size of the air suction port, so that the suction capacity of the air suction port is improved.
Gather the bottom opening part of flowing a section of thick bamboo even and have and be the spiral and gather and flow the board, when the air from gathering flowing a section of thick bamboo bottom and inhale, when gathering flowing, the spiral gathers and flows the board and shunts the air for the air current is the spiral and is drawn into wherein, further improves and gathers a class ability and makes particulate matter fully dispersed, makes it can evenly distributed when being adsorbed by the filter paper, avoids causing the regional granule of filter paper center to gather, leads to the air to pass the hindrance increase of filter paper, reduces the change frequency of filter paper.
The upper clamping plate and the lower clamping plate are arranged in parallel up and down on the outer wall of the sleeve in a sleeved mode, the upper clamping plate is located above the top surface of the adsorption cover and attached to the surface of the adsorption cover, the lower clamping plate is located below the top surface of the adsorption cover, the downward moving height of the sleeve can be limited through the upper clamping plate, and meanwhile the distance between the spray pipe and a workpiece can not float up and down due to human factors in the spray pipe spraying moving process; the lower clamping plate plays a limiting role in the lifting process of the sleeve, and the collision between the spraying plate and the adsorption cover due to the overlarge lifting height of the sleeve is avoided.
Place between platform and the braced frame, braced frame and adsorb and all adopt the mode of dismantling to be connected between the cover, braced frame adopts rubber materials to make, makes things convenient for placing and taking out of work piece, places the braced frame who makes through rubber materials between platform and the adsorption cover simultaneously, has improved the leakproofness of connecting between the three.
Even there is separation gauze between two adjacent slotted hole of lower surface of baffle, use at last baffle and accomplish the back, the work piece surface has been sprayed a plurality of parallel spaced bars, consequently when the baffle sprays when remaining blank region under the use, because the spray tube is when spraying coating, the region at outermost edge must have partly sputter, splash easily on the region of spraying, consequently through setting up separation gauze at baffle lower surface down, the paint vehicle that the spray tube edge was sputtered splashes takes the separation to be absorbed on the gauze, the effect of blockking has been played, avoid the repeated overlapping to scribble the spraying region.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. according to the environment-friendly anti-corrosion treatment method for the household wood board, the upper and lower partition plates, the moving slotted holes in the adsorption cover, the sealing rubber plates in the slotted holes and the clenches are ingeniously arranged, so that the surface of a workpiece can be uniformly sprayed, the uniformity of the whole thickness is improved, the sealing performance of the whole spraying environment can be ensured, paint molecules which are splashed and diffused in the spraying process can only be left in the adsorption cover and cannot be diffused and overflowed in the external environment, and the safety of external workers is ensured;
