Description

Technical Field

[0001] The utility model relates to the field technology of exhaust gas treatment in inkjet rooms, in particular to an exhaust gas treatment device. Background Art

[0002] At present, there are two common types of inkjet rooms:

[0003] One type is a device that designs an inkjet room to provide a special environment for painting operations. It can meet the requirements of painting operations for temperature, humidity, illumination, air cleanliness, etc., and can limit and treat the ink mist and organic waste gas generated during the inkjet operation before discharging. Although it is called an inkjet room, it is more precisely an environmentally friendly painting equipment suitable for fully automatic inkjet processing. After the product is placed in the inkjet room, it is usually not necessary for people to enter the inkjet room for on-site processing operations. For example, CN 220677294 U discloses an exhaust gas treatment device for a paint spraying room, including a paint spraying room, an exhaust gas treatment tower, and a wastewater purification box; by high-pressure spraying on the walls of the paint spraying room, the paint stuck on the walls of the paint spraying room is washed into the drainage chamber, which effectively improves the exhaust gas treatment efficiency in the paint spraying room. The guide fan in the exhaust gas treatment tower transports the smoke sucked by the air pump to the first activated carbon layer, and the strong adsorption of organic matter purifies the gas. The odor adsorption layer removes the odor in the gas, and effectively treats the exhaust gas.

[0004] The other type is for small products that require manual inkjet operations. Some relatively closed rooms are arranged in the building as inkjet rooms, and workers perform inkjet processing on the products on site. Workers wear masks, and the inkjet room is connected to an exhaust pipe to extract the gas in the inkjet room in real time as waste gas and enter the factory's waste gas main pipe. However, the size of the exhaust port is limited and needs to meet the exhaust pipe's displacement\rate requirements. The air cannot be diluted quickly and in time, resulting in a high gas concentration of mixed ink waste gas (ink particles and organic waste gas) in common ordinary inkjet rooms.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0006] In view of this, the utility model aims to solve the deficiencies in the prior art, and its main purpose is to provide an exhaust treatment device, which accelerates the air intake speed of the box body, and quickly flows the gas in the inkjet room into the box body. Due to the setting of the air outlet filter, the ink particles / odor of the gas flowing back to the inkjet room have been greatly reduced, so that the gas in the inkjet room is diluted, and the ambient air in the inkjet room is quickly improved. Moreover, the displacement requirement of the exhaust pipe can still be met.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An exhaust treatment device includes an inkjet waste gas collection box; the inkjet waste gas collection box includes a box body, an air intake filter screen arranged on at least one side of the box body, an exhaust fan arranged in the box body, and an exhaust pipe connected to the top of the box body and extending upward;

[0009] At least another side of the box body is also provided with an air outlet filter screen, and the gas in the inkjet room enters the box body through the air inlet filter screen, a part of the gas is sent back to the inkjet room through the air outlet filter screen, and the other part is discharged upwardly outside the inkjet room through the exhaust pipe.

[0010] As a preferred solution, the air inlet filter is arranged at the front side of the box body, the air outlet filter is arranged at the rear side of the box body, and the exhaust pipe is connected to the top of the box body.

[0011] As a preferred solution, the air intake filter is a detachable structure, and the air intake filter is pulled out upward from the box body for replacement and then a new air intake filter is inserted downward.

[0012] As a preferred solution, a window is reserved on the front side of the box body, and embedding grooves are provided on the left and right sides of the window, and the window and the embedding grooves are both arranged to penetrate upward.

[0013] As a preferred solution, the inkjet waste gas collection box is equipped with a quick-release bracket, which includes a base frame, an extension rod and a locking frame; a first placement position is reserved on the base frame, and the inkjet waste gas collection box is placed on the first placement position, and the extension rod is integrally extended upward from the front side of the base frame, and the locking frame is connected to the rear side of the upper end of the extension rod, so that a second placement position is formed between the locking frame and the upper end of the extension rod, and the exhaust pipe is placed on the second placement position, and the rear end of the locking frame has a locking hole for connecting to a wall.

[0014] As a preferred solution, the base frame includes two left upright poles, two right upright poles, and a front cross bar and a rear cross bar connected between the left upright poles and the right upright poles, and a plurality of reinforcing bars are connected between the tops of the left upright poles and the right upright poles;

[0016] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that it mainly accelerates the air intake speed of the box body, and quickly flows the gas in the inkjet room into the box body. Due to the setting of the air outlet filter, the ink particles / odor of the gas flowing back to the inkjet room have been greatly reduced, so that the gas in the inkjet room is diluted, and the ambient air of the inkjet room is quickly improved. Moreover, it can still meet the displacement requirement of the exhaust pipe.

[0017] Furthermore, the exhaust treatment device has a simple structure, and can replace the exhaust device in the traditional inkjet room. It is suitable for installation and application in various inkjet rooms, and has good versatility and strong practicality.

[0024] Please refer to Figures 1 to 5As shown, it shows the specific structure of an embodiment of the utility model.

[0025] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0026] An exhaust gas treatment device includes a plurality of inkjet rooms 1 and a centralized treatment device located on a higher floor. In this embodiment, the plurality of inkjet rooms 1 are uniformly arranged on the first floor, and the centralized treatment device is arranged on the second floor.

[0027] Each inkjet room 1 is provided with an inkjet station 2; an inkjet waste gas collection box 3 is provided for the inkjet station 2 in the inkjet room 1; the inkjet waste gas collection box 3 includes a box body, an air intake filter 31 provided on at least one side of the box body, an exhaust fan provided in the box body, and an exhaust pipe 4 connected to the top of the box body and extending upward. The upper end of the box body can be connected to an exhaust branch pipe 34, which is connected to the exhaust pipe 4 by the exhaust branch pipe 34. The inkjet waste gas collection box can be customized in size as required, or a plurality of modular inkjet waste gas collection box monomers can be designed. According to the actual situation of the inkjet room, a corresponding number of inkjet waste gas collection box monomers can be selected as required to form an inkjet waste gas collection box assembly of the required size. A quick-install buckle structure 33 can be designed at the assembly, such as a matching structure of a convex and a slot, and a matching structure of a plug-in positioning pin and a positioning hole, which is mainly to strengthen the connection integrity between adjacent monomers. Of course, it is also possible not to set up the quick-install buckle structure, because the inkjet waste gas collection box monomer, which is roughly in the shape of a cube, can be placed and positioned. In this solution, each monomer has an independent exhaust branch pipe 34.

[0028] The air intake filter 31 is a detachable structure. The air intake filter 31 can be pulled out upward from the box body for replacement and then a new air intake filter 31 can be inserted downward. Usually, a first window is reserved at the front side of the box body, and first embedding grooves are provided on the left and right sides of the first window. The first window and the first embedding groove are both provided to penetrate upward. Therefore, the air intake filter 31 can be inserted by aligning the first window and the first embedding groove.

[0029] In particular, at least another side of the housing is further provided with an air outlet filter. The gas of the inkjet room 1 enters the housing through the air inlet filter 31, a part of which is sent back to the inkjet room 1 through the air outlet filter, and the other part is discharged upwardly through the exhaust pipe 4 to the outside of the inkjet room 1. The air outlet filter is also a detachable structure. After the air outlet filter is pulled out of the housing upwards for replacement, a new air outlet filter can be inserted downwards. Usually, a second window is reserved at the rear side of the housing, and second embedding grooves are provided on the left and right sides of the second window. The second window and the second embedding groove are both provided to penetrate upwards. Therefore, the air outlet filter can be inserted into the second window and the second embedding groove. Specifically, air is taken in from the front side of the housing, and the preliminarily purified gas is refluxed into the inkjet room 1 from the rear side of the housing, and the waste gas is discharged to the outside of the inkjet room 1 from the top of the housing. The refluxed gas is filtered and purified twice, while the exhaust gas here is only purified once by the front air intake filter 31. By adopting this air intake, reflux and exhaust method, a sufficiently large air intake surface (air intake filter 31) can be designed to accelerate the air intake speed of the box, and the gas in the inkjet room 1 can flow quickly into the box. Due to the setting of the air outlet filter, the ink particles / odor of the gas refluxed to the inkjet room 1 have been greatly reduced, so that the gas in the inkjet room 1 is diluted, and the displacement requirement of the exhaust pipe 4 can still be met. The main material of the air intake filter and the air outlet filter is filter cotton, which can absorb and filter small particles of ink. The filter cotton is a consumable part and needs to be replaced regularly.

[0030] The inkjet waste gas collection box 3 is equipped with a quick-release bracket. During installation, the quick-release bracket is placed on the floor 100 of the inkjet room 1. The quick-release bracket includes a base frame, an extension rod 36 and a locking frame 32. A first placement position is reserved on the base frame, and the inkjet waste gas collection box 3 is placed on the first placement position. The extension rod is integrally extended upward from the front side of the base frame, and the locking frame 32 is connected to the rear side of the upper end of the extension rod 36, so that a second placement position is formed between the locking frame 32 and the upper end of the extension rod. The exhaust pipe 4 is placed on the second placement position, and the rear end of the locking frame 32 has a locking hole for connecting to the wall. Figure 4 and Figure 5As shown, the base frame includes two left-side uprights 35, two right-side uprights, and a front cross bar and a rear cross bar connected between the corresponding left-side uprights and the right-side uprights. A plurality of reinforcing bars are also connected between the tops of the left-side uprights and the right-side uprights to form a top surface on the reinforcing bars for placing the ink supply and inkjet waste gas collection box 3; two extension rods 36 are provided, and are respectively extended upward from the left-side uprights 35 and the right-side uprights on the front side; a baffle bar is connected between the two extension rods, and the baffle bar is located above the front cross bar and lower than the top of the extension rod 36, so that the front side of the inkjet waste gas collection box 3 is positioned and stopped by the baffle bar. The locking frame 32 is provided with two, each of which includes a longitudinal rod 37 extending forward and backward, a locking vertical rod 38 extending vertically, and a supporting diagonal rod 39. The front end of the longitudinal rod 37 is connected to the rear side of the upper end of the extension rod 36, and the locking vertical rod 38 is connected to the rear end of the longitudinal rod 37. The locking hole is opened on the locking vertical rod 38, and the locking hole passes through the locking vertical rod 38 front and back. The upper end of the supporting diagonal rod 39 is connected to the lower end of the longitudinal rod 37, and the supporting diagonal rod 39 is extended backward and downward and its lower end is connected to the front side of the locking vertical rod 38, thus forming a triangular support structure with simple structure and good stability.

[0031] The centralized processing equipment is arranged on a set floor, and the set floor is higher than the floor where all inkjet rooms 1 are located; the exhaust pipe 4 is connected upward to the centralized processing equipment. The centralized processing equipment is equipped with an electric control cabinet. The centralized processing equipment includes a gas collecting box 6, the air inlet end of which is connected to the exhaust pipe 4 to collect the waste gas from the inkjet waste gas collection box 3 into the gas collecting box 6, and a gas collecting fan is arranged in the gas collecting box 6; the gas from the gas collecting box 6 is sent to the processing center 7 for processing and then discharged. Specifically, the processing center 7 includes at least a spray tower and an activated carbon adsorption tower, so the air outlet end of the gas collecting box 6 is connected to the spray tower and the activated carbon adsorption tower in sequence, and the air outlet end of the activated carbon adsorption tower is connected to an exhaust pipe, and the exhaust pipe is equipped with a main fan 8. A number of gas collecting pipe joints 5 are reserved at the air inlet end of the gas collecting box 6, and the exhaust pipe 4 is detachably connected to the corresponding gas collecting pipe joints 5, and an air inlet switch regulating valve 11 is arranged on the gas collecting pipe joint 5. A filter box 12 may also be provided at the air inlet end of the air collecting box 6. At least one of the air collecting pipe joints 5 is connected to a bypass pipe, and the bypass pipe is equipped with a centrifugal fan 10.

[0032] The entire inkjet room exhaust gas treatment system can quickly improve the ambient air of inkjet room 1 by extracting the exhaust gas from inkjet room 1 in advance at inkjet station 2 and filtering out dust particles, avoiding negative physical effects on operators. It does not need to configure an exhaust gas treatment device separately, and is especially suitable for situations where small products require manual inkjet operations, with a better working environment and a better working experience. In addition, the exhaust gas is centrally treated on higher floors, which meets the requirements of gas upward flow and transportation, is easy to manage, and saves exhaust gas treatment costs.

[0033] The design focus of the utility model is that it mainly accelerates the air intake speed of the box body, and quickly flows the gas in the inkjet room into the box body. Due to the setting of the air outlet filter, the ink particles / odor of the gas flowing back to the inkjet room have been greatly reduced, so that the gas in the inkjet room is diluted, and the ambient air of the inkjet room is quickly improved. Moreover, the displacement requirement of the exhaust pipe can still be met.

[0034] Furthermore, the exhaust treatment device has a simple structure, and can replace the exhaust device in the traditional inkjet room. It is suitable for installation and application in various inkjet rooms, and has good versatility and strong practicality.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
