Description

Technical Field

[0001] The utility model relates to the technical field of industrial coating, in particular to the field of capturing, separating and collecting coating paint mist, and specifically is a universal labyrinth-type paint mist collector. Background Art

[0002] Painting is a highly polluting and energy-intensive industry. The collection of paint mist generated by the painting production line has always been an important issue in the industry, especially for the working environment of the vehicle factory painting line, which will generate a large amount of overspray paint mist. In response to increasingly stringent environmental regulations and the trend of users' own increasing attention to various factors such as solid waste treatment and energy consumption management, painting equipment manufacturers are also constantly researching and exploring, and have launched many new solutions. Among them, the design of dry painting line combined with paint mist collector has emerged among many solutions, is widely used, and is also considered an important development direction of this technology.

[0003] Conventional paint mist collectors are equipped with multiple groups of paint mist collection units, with specific air ducts formed between the units. Combined with a negative pressure device, the air carrying paint particles hits the paint mist collection unit at high speed. The paint particles that hit the paint mist collection unit will adhere to the paint mist collection unit and be captured. This method can improve the capture ability of paint particles and greatly improve the separation effect of paint mist. However, in actual applications, the following problems often occur:

[0004] 1. Along the air flow direction, the paint mist collection unit close to the device inlet is always the first to be adhered by paint particles and is easily blocked. The paint mist collection unit close to the device outlet collects very few paint mist particles, resulting in a waste of collection unit resources.

[0005] 2. The structure of the paint mist collection unit is single, resulting in a single air duct pattern for the finished paint mist collector, which cannot meet the needs of different spraying workshops. Summary of the invention

[0006] The purpose of the utility model is to overcome the defects of the above-mentioned prior art and to provide a universal labyrinth paint mist collector, in which the paint mist collecting units can form air ducts as needed according to different material placement methods to meet different needs.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a universal maze-type paint mist collector, including a device shell, a device inlet, and a device outlet, characterized in that: a plurality of rows of paint mist collection units are arranged in the device shell, and the plurality of rows of paint mist collection units are fixedly installed through slots reserved in the device shell, the paint mist collection units are composed of a square frame and filter materials, and the filter materials are selectively filled in the separation space formed by the square frame.

[0008] Preferably, the square frame is formed by splicing multiple groups of transverse and longitudinal rods to form separation spaces between the multiple groups of transverse rods and the multiple groups of longitudinal rods, and multiple groups of high-strength connecting members are also arranged between the transverse rods and the longitudinal rods.

[0009] Preferably, the connecting piece is made of any one of metal material or plastic material.

[0010] Preferably, the filter material is filled in a manner that, along the mainstream air direction, while ensuring that there is a spare separation space in each row or column of the square frame, the filter materials of multiple rows of paint mist collection units on the device inlet side are randomly filled in the separation space, and the last row of paint mist collection units fills the frame with the filter material.

[0011] Preferably, the amount of the filter material filled increases gradually along the mainstream direction of air.

[0012] Preferably, the number of slots reserved in the device housing is 6-9 groups, and the paint mist collection units are arranged in 3-9 rows.

[0013] Preferably, the filter material is a fiber filter material.

[0014] Preferably, the square frame is made of any one of metal material or plastic material.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) According to the universal maze-type paint mist collector provided by the utility model, the filter materials of the paint mist collection units in the device are randomly filled, and a maze-type air duct can be formed as needed to ensure air circulation. At the same time, since the amount of filter material filled gradually increases along the mainstream direction of the air, the paint particles can be captured step by step. Each row of paint mist collection units can play a role, and the last row of square frames is filled with filter materials, which can achieve comprehensive capture of paint particles.

[0017] (2) According to the universal labyrinth paint mist collector provided by the utility model, the paint mist collection unit is an independent individual, and the number of paint mist collection units can be appropriately adjusted according to actual production needs. For small painting workshops, the number of paint mist collection units can be reduced to save materials, while for large painting workshops, the number of paint mist collection units can be increased to improve the collection effect.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0032] See also Figure 1-12The utility model provides a technical solution: a universal labyrinth paint mist collector, including a device housing 2, a device inlet 1, a device outlet 4, and 5 rows of paint mist collection units 3 are inserted into the reserved slots 5 in the 1st, 3rd, 5th, 7th, and 9th rows in the device housing along the air mainstream direction. The square frame 31 of the paint mist collection unit is spliced ​​by 10 plastic rods 311 in the horizontal and vertical directions, and fixed by high-strength plastic connectors 312, so as to form 9*9 groups of separation spaces for placing fiber filter materials 32. Figure 7-11 As shown, along the mainstream direction of air, fiber filter materials are randomly placed in the partition spaces of the square frames of the paint mist collection units in the first four rows, leaving partition spaces to ensure air circulation, as shown in FIG. Fig.12 As shown, in the last row (i.e., the 5th row), the square frame of the paint mist collection unit is filled with fiber filter materials.

[0033] This technical solution is applied to medium-sized spray workshops and is suitable for general situations. In actual application, the paint mist particles formed in the spray workshop pass through the negative pressure device and flow through the paint mist collector. The high-speed air with paint particles hits the paint mist collection unit and is adhered to the fiber filter material. The uncaptured paint mist enters the next-level paint mist collection unit through the empty separation space in the front row and is captured step by step. At the same time, since the last row of paint mist collection units is filled with fiber materials, the paint particles not captured by the front row are completely captured here. Example

[0034] See also Figure 1-12 The utility model provides a technical solution: a universal labyrinth paint mist collector, including a device housing 2, a device inlet 1, a device outlet 4, and four rows of paint mist collection units 3 are inserted into the reserved slots 5 in the first, fourth, eighth, and ninth rows in the device housing. The square frame 31 of the paint mist collection unit is composed of six horizontal and eight vertical metal rods 311, and is fixed by high-strength metal connectors 312, so as to form 5*7 groups of separation spaces for placing fiber filter materials 32. Figure 7-11 As shown, along the mainstream direction of air, fiber filter materials are randomly placed in the separation spaces of the square frames of the paint mist collection units in the first three rows, leaving separation spaces to ensure air circulation, such as Fig.12 As shown, the square frame of the paint mist collection unit in the last row (i.e. the 4th row) is filled with fiber filter materials.

[0035] This technical solution installs fewer paint mist collection units and is suitable for small spray workshops. Since there are fewer paint mist collection units installed, the square frame is spliced ​​with metal rods and fixed by high-strength metal connectors, which is unstable when placed for use. In actual application, the paint mist particles formed in the spray workshop pass through the negative pressure device and flow through the paint mist collector. The high-speed air with paint particles hits the paint mist collection unit and is adhered to the fiber filter material. The paint mist that is not captured enters the next level of paint mist collection unit through the empty separation space in the front row and is captured step by step. At the same time, since the last row of paint mist collection units is covered with fiber materials, the paint particles that are not captured by the front row are completely captured here.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
