Abstract

The invention discloses a convex bottom middle air knife double-turning plate quick color changing spray booth which comprises a spray booth body and a powder cleaning device arranged at the bottom of the spray booth body, wherein the powder cleaning device comprises a bottom plate with an inverted V-shaped cross section, an air knife arranged at the top of the bottom plate and a recovery cavity used for recovering dust, a plurality of air holes are formed in the side wall of the air knife and connected with an air source, a gap is formed between the two ends of the bottom plate and the side wall of the spray booth body, the inlet of the recovery cavity is communicated with the gap, and the outlet of the recovery cavity is communicated with an air pipe. According to the invention, the bottom plate with the inverted V-shaped cross section is adopted, dust can slide to the gap under the action of gravity of the dust falling on the bottom plate, and meanwhile, air holes in the side wall of the air knife blow air outwards, so that the dust is accelerated to slide to the gap. Therefore, the dust removing efficiency of the spray room adopting the structure is higher, an air source with high air pressure is not required to be configured, the structure is simple, and the cost is low.

Description

The quick colour changing spray of the two turnover panels of air knife room in a kind of sunken bottom

Technical field

The present invention relates to the quick colour changing spray of the two turnover panels of air knife room in a kind of sunken bottom.

Background technology

The spray room is the place of workpiece being carried out spray, and workpiece can produce a large amount of dust in the process of spray, therefore sprays the room and all need configure the device of removing and reclaiming dust, and this device operated by rotary motion is in bottom, spray room.Existing remove and reclaim in the device of dust, bottom, spray room is typically provided to planar structure, then in the centre or two ends air knife is set, the dust on the bottom surface is blowed to the entrance of the device of collecting dust; The removing of this class formation and recovery dust device are owing to adopting flat bottom, be unfavorable for that dust is towards the entrance motion of collecting the dust device, its removing and recovery dust efficient are lower, and air knife need configure more anticyclonic source of the gas, dust accumulation can often occur in the phenomenon of bottom surface, therefore be necessary to provide the higher spray of a kind of removing dust efficient room.

Summary of the invention

In order to address the above problem, the invention provides the quick colour changing spray of the two turnover panels of air knife room in a kind of sunken bottom.

The technical solution adopted for the present invention to solve the technical problems is:

The quick colour changing spray of the two turnover panels of air knife room in a kind of sunken bottom, comprise spray room body and be arranged on the clear powder device that sprays body bottom, room, described clear powder device comprises that cross section is reverse V-shaped base plate, is arranged on the air knife at base plate top and is used for reclaiming the recycling cavity of dust, be provided with some pores on the described air knife sidewall, be provided with the gap between base plate two ends and the spray room body sidewall, described recycling cavity entrance is communicated with the gap, and recycling cavity is provided with an outlet that can be connected with dust pelletizing system.

Described gap location is provided with rotating turnover panel.

Described turnover panel is fixedly connected with a rotating shaft, described rotating shaft is rotating to be installed in the spray room body, rotating shaft is parallel with base plate with spray room body sidewall, described rotating shaft is fixedly connected with an end of a plate, this connecting plate other end and a cylinder or output shaft articulate, described cylinder integral body is articulated on the spray room body.

The invention has the beneficial effects as follows: it is reverse V-shaped base plate that the present invention adopts cross section, because the Action of Gravity Field of itself can slide toward gap location, and the pore on the air knife sidewall is blown outward simultaneously, accelerates dust and slides towards gap location after dust drops on the base plate.As seen adopt the spray room removing dust efficient of said structure higher, need not to configure the very high source of the gas of air pressure, simple in structure, with low cost.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples:

Fig. 1 is structural representation of the present invention;

Fig. 2 is the structural representation of clear powder device among the present invention;

Fig. 3 is the partial enlarged drawing A of Fig. 2.

The specific embodiment

With reference to Fig. 1, Fig. 2 and Fig. 3, the present invention is the quick colour changing spray of the two turnover panels of air knife room in a kind of sunken bottom, comprise spray room body and be arranged on the clear powder device that sprays body bottom, room, clear powder device comprises that cross section is reverse V-shaped base plate 2, be arranged on the air knife 3 at base plate 2 tops and be used for reclaim the recycling cavity 4 of dust, be provided with some pores 7 on air knife 3 sidewalls, pore 7 is connected with source of the gas, be provided with gap 5 between base plate 2 two ends and the spray room body sidewall, recycling cavity 4 entrances are communicated with gap 5, recycling cavity 4 is provided with an outlet 8 that can be connected with dust pelletizing system, outlet 8 can be connected with the next stage system by airduct 13, airduct employing PVC material is made (prior art adopts metal tube to make), adopts the making of PVC material can reduce sticking on airduct 13 inwalls of dust.It is reverse V-shaped base plate 2 that the present invention adopts cross section, slide in after dust drops on the base plate 2 because past 5 places, gap of the Action of Gravity Field of itself meeting, the simultaneously outward step air blowing of pore on air knife 3 sidewalls (by pulser control air blowing process) is accelerated dust and is slided at 5 places towards the gap.As seen adopt the spray room removing dust efficient of said structure higher, need not to configure the very high source of the gas of air pressure, simple in structure, with low cost.

Before changing the powder color, need dust in the whole spray room body is cleaned out, in order to clear up more easily the dust that is retained in the recycling cavity 4, as shown in the figure, 5 places, gap are provided with rotating turnover panel 6.During normal operation, turnover panel 6 rotation is to parallel with base plate 2, and dust enters recycling cavity 4 under himself gravity, air exhauster and air knife effect, then enter in the next stage device by tracheae 8 and process; When thoroughly cleaning dust, need can with turnover panel 6 rotations to vertical state, be convenient to clean recycling cavity 4 interior dust.

As shown in the figure, turnover panel 6 can be installed on the spray room body 1 by the following specific embodiment: turnover panel 6 is fixedly connected with a rotating shaft 9, rotating shaft 9 rotating being installed in the spray room body 1, rotating shaft 9 is parallel with base plate 2 with spray room body 1 sidewall, rotating shaft 9 is fixedly connected with an end of a plate 10, the output shaft 12 of these connecting plate 10 other ends and a cylinder 11 articulates, and cylinder 11 integral body are articulated on the spray room body 1.

Above-described embodiment is preferred version of the present invention, and the present invention also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite of spirit of the present invention, the modification that these are equal to or replacement all are included in the application's claim limited range.
