Abstract

The utility model discloses a protruding bottom middle air knife double reverse turning bed quick color changing spray room which comprises a spray room body and a powder cleaning device arranged at the bottom of the spray room body. The powder cleaning device comprises a base plate with an inverted-V-shaped cross section, an air knife arranged at the top of the base plate and a recovery cavity for recovering dust. A plurality of air holes are formed in the side wall of the air knife and are connected with an air source. Clearance is formed between two ends of the base plate and side walls of the spray room body. An inlet of the recovery cavity is communicated with the clearance. An outlet of the recovery cavity is communicated with an air tube. According to the protruding bottom middle air knife double reverse turning bed quick color changing spray room, the base plate with the inverted-V-shaped cross section is adopted, after falling on the base plate, the dust can slide toward the clearance due to self gravity, meanwhile, the dust is quickened to slide toward the clearance due to the fact that the air holes on the side wall of the air knife blow air outward. Consequently, the spray room with the structure is high in dust cleaning efficiency, does not need an air source with high air pressure, and is simple in structure, and low in cost.

Description

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

Technical field

The utility model 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 workpiece to be carried out the place of 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, therefore dust accumulation can often occur in the phenomenon of bottom surface, be necessary to provide the higher spray of a kind of removing dust efficient room.

The utility model content

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

The technical scheme that its technical problem that solves the utility model adopts 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 described air knife sidewall, be provided with the gap between base plate two ends and 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, rotating being arranged on of described rotating shaft sprayed in the 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 the output shaft pivot joint, described cylinder integral body is articulated on spray room body.

The beneficial effects of the utility model are: it is reverse V-shaped base plate that the utility model adopts cross section, Action of Gravity Field due to itself after dust drops on base plate can slide toward gap location, pore on the air knife sidewall is blown outward simultaneously, accelerates dust and slides towards gap location.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

Below in conjunction with drawings and Examples, the utility model is further illustrated:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of clear powder device in the utility model;

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 utility model 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 reclaiming 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 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 adopts the PVC material to make (prior art adopts metal tube to make), adopt the making of PVC material can reduce sticking on airduct 13 inwalls of dust.It is reverse V-shaped base plate 2 that the utility model adopts cross section, Action of Gravity Field due to itself after dust drops on base plate 2 can slide at 5 places toward the gap, pore step air blowing outward on air knife 3 sidewalls simultaneously (controlling air blowing process by pulser) 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 whole spray room body is cleaned out, in order to clear up more easily the dust that is retained in 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 the interior dust of recycling cavity 4.

As shown in the figure, turnover panel 6 can be arranged on by the following specific embodiment and spray on room body 1: turnover panel 6 is fixedly connected with a rotating shaft 9, rotating being arranged on of rotating shaft 9 sprayed in 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, output shaft 12 pivot joints of these connecting plate 10 other ends and a cylinder 11, cylinder 11 integral body are articulated in sprays on room body 1.

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