Description

Paint mist catching device in spray booth
Technical field
The utility model belongs to paint mist catching device in spray booth, is specifically related to be used to catch in a kind of paint spray booth tank the device of coating cloud.
Background technology
In the wet type spray chamber sink structure, be used for the Venturi tube structure that paint spray booth's coating cloud is caught, adopt relatively milder break-in structure between contraction section and trunnion and the diffuser, the current bump is few, can not satisfy the requirement that tank high efficiency coating cloud in paint spray booth's is caught, catching height, the length of the rinse water disperse water particle of coating cloud simultaneously can not regulate, and perhaps regulates inconvenient.Some other version is complicated simultaneously, perhaps makes processing etc. and has relatively high expectations.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, and can efficiently catch paint spray booth's tank mist catching device of coating cloud, to address the above problem.
The technical solution of the utility model is a paint mist catching device in spray booth, it comprises housing, the coating cloud that is provided with in the housing is caught Venturi, and the axes intersect of the port of export of the axis of the contraction section of Venturi and the trunnion of Venturi forms the first bump break-in; Exit end face with respect to trunnion is provided with baffle plate, forms the second bump break-in; The outlet of the diffuser of Venturi and the outlet of trunnion are oppositely arranged, and form the revolving structure of 180 degree.
The outlet front end place of the diffuser of described Venturi is provided with cistern, and cistern is located at below the trunnion.
The trunnion of described Venturi comprises the following current deflector that is connected with the Venturi contraction section, the first bump guide direction variable plate that is connected with the following current deflector, the trunnion outlet guide direction variable plate that is connected with the Venturi contraction section forms the trunnion outlet between the trunnion outlet guide direction variable plate and the first bump guide direction variable plate.
The exit of the diffuser of described Venturi is provided with diffusing opening size adjustment plate.
This paint mist catching device in spray booth adopts twice collision of current to change direction, because under certain wind speed and certain water yield circulation, rinse water forms plane current shape by the aditus laryngis place and flows to venturi aditus laryngis place, wind speed is bigger at venturi aditus laryngis place, the aditus laryngis place will form the fluid turbulence effect, rinse water flows down along deflector, with certain speed bump first bump guide direction variable plate, and the gusset that is provided with at the aditus laryngis place, make rinse water form fragmentary current, with the vertical or vertical also baffle plate of slightly angled d of certain speed bump, make rinse water spread again, atomizing, thus coating cloud caught.The rinse water of having caught coating cloud is overflowed with the current that enter the aditus laryngis place then in the other direction because the gravity effect continues to flow in the middle cistern that the diffusing opening place of lower floor is provided with, and flows into the tank master of paint spray booth again and cleans in the water channel.Flow to from the rinse water by mist catching device integral body, the rinse water of returning turnback flows to design and can carry out the secondary seizure to the coating cloud of catching at large, thereby has improved the efficient of catching coating cloud.This mist catching device enters in rinse water and is provided with the little cistern of one deck in paint spray booth's major trough water channel again, and coating cloud is caught once more, thereby has improved capturing efficiency.It is simple in structure, and convenient processing and manufacture has solved some problems such as existing mist catching device manufacturing, installation.

The specific embodiment
Present embodiment is used for the explanation to technical solutions of the utility model, and protection domain of the present utility model is not limited to following structure.
As shown in Figure 1, catch Venturi for coating cloud in housing 5 tops, housing 5 and coating cloud are caught between the Venturi reinforcement, fixture 8 are set, and its structure is not this tired stating.Water channel UNICOM (not shown) is cleaned with the tank master of paint spray booth in housing 5 bottoms 9.
Coating cloud is caught Venturi and is comprised contraction section 1, and the contraction section 1.1 and 1.2 that contraction section 1 is " V " by two interconnective cross sections constitutes.The angular range of the opening of the contraction section 1.1 of " V " and the angle a of horizontal plane is 25 °~45 °, and the contraction section 1.2 of " V " that is connected with the contraction section 1.1 of " V " is 8 °~25 ° with the angular range of the angle b of vertical plane.
Be connected to trunnion 2 with contraction section 1.2 tail ends of " V "; Trunnion 2 comprises the following current deflector 2.1 that contraction section connects, the first bump guide direction variable plate 2.2 that is connected with following current deflector 2.1, the trunnion outlet guide direction variable plate 2.3 that is connected with the Venturi contraction section forms trunnion outlet 2.4 between the trunnion outlet guide direction variable plate 2.3 and the first bump guide direction variable plate 2.2.The first bump guide direction variable plate 2.2 is provided with gusset 2.5.Gusset 2.5 forms the triangle guiding, makes current rush at trunnion outlet guide direction variable plate 2.3.Trunnion exports 2.4 opposites and is provided with baffle plate 7.Has an angle d, 90 °<d≤130 ° between baffle plate 7 and the trunnion outlet guide direction variable plate 2.3.
Outlet front end place at the diffuser 3 of Venturi is provided with cistern 3.1, and cistern 3.1 is located at below the trunnion 2.Cistern 3.1 comprises the pool wall 3.3 that is made of inner walls, at the bottom of the pond that inner walls connects 3.2, connects overflow wall 3.4 on 3.2 at the bottom of the pond.3.2 establish evacuation port 6 at the bottom of the pond.
The outlet of the diffuser of 2.2 times Venturis of the first bump guide direction variable plate is provided with diffusing opening size adjustment plate 4.Diffusing opening size adjustment plate comprises fixed head 4.1, connects movable plate 4.2 on the fixed head 4.1; Offer the guiding slotted eye on the movable plate, establish connecting hole on the fixed head, connecting bolt between guiding slotted eye on the movable plate and the connecting hole on the fixed head.
Constitute the outlet of Venturi diffuser between overflow wall 3.4 and the adjustable plate 4.
Whole venturi mist catching device is provided with skeleton and reinforcement, and is arranged in paint spray booth's tank, and paint spray booth's tank also is provided with the labyrinth plate.In the needs maintenance, can open maintenance evacuation port 6, the rinse water in the emptying cistern.
[0020] shown in Fig. 2,3, when paint spray booth's operate as normal, the needed rinse water in spray booth chamber is caught coating cloud by this jockey.At first rinse water is by the contraction section of venturi, because under certain wind speed and certain water yield circulation, rinse water forms plane current shape by trunnion section place and flows to Venturi throat section place, wind speed is bigger at Venturi throat section place, trunnion section place will form the fluid turbulence effect, rinse water flows down along deflector, impinge upon trunnion section place with certain speed and be set to have gusset to upper angle, make rinse water form fragmentary current, with the vertical or vertical also baffle plate of slightly angled setting of certain speed bump, make rinse water spread, atomizing, thus coating cloud caught; The rinse water of having caught coating cloud is overflowed with the current that enter the aditus laryngis place then in the other direction because the gravity effect continues to flow in the middle cistern that the diffusing opening place of lower floor is provided with, and flows into the tank master of paint spray booth again and cleans in the water channel.This mist catching device enters in rinse water and is provided with the little cistern of one deck in paint spray booth's major trough water channel again, and coating cloud is caught once more, thereby has improved capturing efficiency.
