Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, and specifically relates to a waste gas treatment device for adhesive processing. Background Technology

[0002] The waste gas generated during adhesive processing contains various harmful substances, and direct emission of these substances can seriously endanger human health, the environment, and production safety. Therefore, waste gas treatment is crucial to remove toxic and harmful substances (such as formaldehyde, benzene compounds, and volatile organic compounds) and prevent respiratory diseases, nervous system damage, and even cancer caused by inhalation of these fumes by operators and nearby residents. By treating the waste gas, the emission of pollutants such as volatile organic compounds (VOCs), particulate matter, and acidic gases (such as sulfur dioxide and nitrogen oxides) can be reduced, thus preventing atmospheric pollution.

[0003] In a prior art (application number 202222072083.8), an adhesive processing waste gas treatment device has a vertically moving pressure plate whose through holes are easily blocked by particulate matter in the adhesive waste gas during operation. This blockage causes the pressure plate to compress the structural cavity during later use, thus affecting the entry of waste gas and reducing the waste gas treatment effect. Utility Model Content

[0004] The purpose of this invention is to provide a waste gas treatment device for adhesive processing, which can solve the above-mentioned technical problems.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] This utility model provides a waste gas treatment device for adhesive processing, including a housing, an inner partition plate, a dispersion tube, stirring blades, and a baffle plate. The inner partition plate is installed inside the housing, dividing the housing into a primary absorption chamber and a secondary absorption chamber. The air inlet pipe passes through the housing and extends into the primary absorption chamber. Two primary dispersion discs are installed on the air inlet pipe in the primary absorption chamber. The dispersion tube is installed on the inner partition plate. Two secondary dispersion discs are installed on the dispersion tube in the secondary absorption chamber. Stirring blades are installed in both the primary and secondary absorption chambers inside the housing. Two sealing covers, corresponding to the absorption chamber and the secondary absorption chamber respectively, are installed on the housing. A rotating shaft is rotatably mounted on the sealing cover. The stirring blades are installed on the lower side of the rotating shaft. A secondary pulley set and a main pulley set are arranged above the sealing cover. The secondary pulley set is used to drive the two rotating shafts to rotate synchronously. A drive motor is installed on one of the sealing covers. The main pulley set is installed on the output shaft of the drive motor and one of the rotating shafts, and is used to drive the motor to drive the rotation of one of the rotating shafts.

[0007] A delivery pump and a discharge pump are installed on the two sealing covers. A suction pipe is installed through the sealing cover and installed at the inlet end of the delivery pump and the discharge pump. A delivery pipe is provided in the primary absorption chamber and installed at the outlet end of the dispersion pipe and the delivery pump, and passes through one of the sealing covers.

[0008] The primary absorption chamber and the secondary absorption chamber inside the box are each equipped with three baffles, which are distributed in a 90° rotation around the axis of rotation.

[0009] When using the above-mentioned waste gas treatment device for adhesive processing, the controller starts the drive motor. One shaft rotates under the drive of the main pulley set, while the secondary pulley set drives the other shaft to rotate, so that the two shafts rotate synchronously. The shafts drive the stirring blades to rotate, and the stirring blades stir the absorbent liquid in the primary absorption chamber and the secondary absorption chamber inside the box. The air inlet pipe delivers the waste gas to the primary dispersion plate. The waste gas emerges from the absorbent liquid in the primary absorption chamber. The rotating absorbent liquid drives the waste bubbles to rotate. By controlling the extension or retraction of the push-pull electric push rod, the linkage plate and linkage frame move synchronously. The linkage frame drives the three sets of lifting shafts to slide on the sealing cover. The lifting shafts drive the baffle plate to block the rotating absorbent liquid, so that the waste bubbles in the absorbent liquid are blocked by the baffle plate and flow downward, thereby prolonging the residence time of the waste bubbles in the absorbent liquid. At the same time, the waste gas emerging from the primary absorption chamber is extracted by the delivery pump and delivered to the secondary absorption chamber, where it is fully mixed and absorbed with the rotating absorbent liquid again. This design improves the absorption effect of the waste gas and facilitates the replacement of the absorbent liquid later, realizing recycling.

[0010] Preferably, three sets of lifting shafts that extend into the housing are slidably installed on the sealing cover. Each set of lifting shafts includes two shafts, one long and one short. The baffle is installed on the lower side of the lifting shafts. A linkage frame is provided above the sealing cover. The upper sides of the three sets of lifting shafts are all installed on the linkage frame.

[0011] Preferably, a linkage plate is provided above the two sealing covers, the linkage plate is installed on the two linkage frames, a push-pull electric push rod is provided above the box body, the extended end of the push-pull electric push rod is installed on the linkage plate, the fixed end of the push-pull electric push rod is installed on the fixed seat, and the fixed seat is installed on the two sealing covers.

[0012] Preferably, two drain pipes are installed on the lower side of the side plate of the box, corresponding to the primary absorption chamber and the secondary absorption chamber respectively. Two replenishment pipes are installed on the upper side of the side plate of the box, corresponding to the primary absorption chamber and the secondary absorption chamber respectively. A discharge pipe is installed at the outlet end of the discharge pump on the top of the box.

[0013] Preferably, the minimum distance between the rotation radius of the stirring blade and the baffle is set to be more than 1.5 times the length of the stirring blade.

[0014] Preferably, all three baffles are tilted at 60°.

[0015] The beneficial effects are:

[0016] 1. This utility model, through an air inlet pipe, a dispersion pipe, and a conveying pipe, allows the waste gas output from the primary dispersion disc to be absorbed by the absorbent liquid in the primary absorption chamber, and then conveyed to the absorbent liquid in the secondary absorption chamber by a conveying pump. At the same time, when the waste gas is absorbed in the absorbent liquid in the box, the stirring blades are driven to rotate, and in conjunction with the baffle plate, the residence time of the waste gas in the absorbent liquid is extended, thereby improving the absorption effect. Meanwhile, the particulate matter in the waste gas can be mixed in the absorbent liquid in the primary absorption chamber, so that the particulate matter can be discharged later by replacing the absorbent liquid, thus maintaining the cyclic absorption and treatment effect of the device on waste gas.

[0017] 2. This utility model uses a push-pull electric push rod, a linkage frame, a linkage plate, and a lifting shaft to move the baffle plate up and down. When the stirring blades rotate and drive the absorbent liquid to rotate, the baffle plate, which moves up and down, can impact and mix the waste gas contained in the absorbent liquid downwards, thereby increasing the mixing and absorption time of the waste gas and the absorbent liquid and improving the treatment effect of the waste gas.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-2 As shown, a waste gas treatment device for adhesive processing includes a housing 1, an inner partition plate 1a, an air inlet pipe 3, a dispersion pipe 5, a stirring blade 7b, and a baffle plate 9b. The inner partition plate 1a is installed inside the housing 1, dividing the housing 1 into a primary absorption chamber and a secondary absorption chamber. The air inlet pipe 3 penetrates the housing 1 into the primary absorption chamber. Two primary dispersion discs 3a are installed on the air inlet pipe 3 in the primary absorption chamber. The dispersion pipe 5 is installed on the inner partition plate 1a. Two secondary dispersion discs 5a are installed on the dispersion pipe 5 in the secondary absorption chamber. The primary absorption chamber and the secondary absorption chamber are connected in the housing 1. Each cavity is equipped with a stirring blade 7b. The housing 1 is equipped with two sealing covers 2 corresponding to the absorption cavity and the secondary absorption cavity, respectively. A rotating shaft 7 is rotatably mounted on the sealing cover 2. The stirring blade 7b is mounted on the lower side of the rotating shaft 7. A secondary pulley set 7a and a main pulley set 8a are arranged above the sealing cover 2. The secondary pulley set 7a is used to drive the two rotating shafts 7 to rotate synchronously. A drive motor 8 is mounted on one of the sealing covers 2. The main pulley set 8a is mounted on the output shaft of the drive motor 8 and on one of the rotating shafts 7, and is used to drive the motor 8 to drive one of the rotating shafts 7 to rotate.

[0024] A conveying pump 4 and a discharge pump 6 are installed on two sealing covers 2. A suction pipe 41 is installed through the sealing cover 2. The suction pipe 41 is installed at the inlet end of the conveying pump 4 and the discharge pump 6. A conveying pipe 42 is provided in the initial absorption chamber. The conveying pipe 42 is installed at the outlet end of the dispersion pipe 5 and the conveying pump 4, and passes through one of the sealing covers 2.

[0025] Three baffles 9b are installed in both the primary absorption chamber and the secondary absorption chamber inside the housing 1. The three baffles 9b are distributed in a 90° rotation around the rotating shaft 7.

[0026] As an optional implementation, three sets of lifting shafts 9a are slidably installed on the sealing cover 2, extending into the housing 1. Each set of lifting shafts 9a includes two shafts, one long and one short. Baffles 9b are installed on the lower side of the lifting shafts 9a. A linkage frame 9 is provided above the sealing cover 2. The upper sides of the three sets of lifting shafts 9a are all installed on the linkage frame 9. This arrangement allows the linkage frame 9 to synchronously drive the three sets of lifting shafts 9a to move up and down, thereby realizing the synchronous lifting and lowering adjustment of the three baffles 9b.

[0027] See attached document Figure 2A linkage plate 10 is provided above the two sealing covers 2. The linkage plate 10 is installed on the two linkage frames 9. A push-pull electric push rod 11 is provided above the box body 1. The extended end of the push-pull electric push rod 11 is installed on the linkage plate 10, and the fixed end of the push-pull electric push rod 11 is installed on the fixed seat 12. The fixed seat 12 is installed on the two sealing covers 2. This arrangement allows the push-pull electric push rod 11 to drive the linkage plate 10 to move synchronously when it extends or retracts. This, in turn, drives the lifting shaft 9a through the linkage frame 9 to adjust the height of the baffle plate 9b, thereby enhancing the blocking effect of the baffle plate 9b on the rotating absorbent liquid.

[0028] Furthermore, two drain pipes 14 are installed on the lower side of the side plate of the housing 1, corresponding to the primary absorption chamber and the secondary absorption chamber respectively. Two replenishment pipes 15 are installed on the upper side of the side plate of the housing 1, corresponding to the primary absorption chamber and the secondary absorption chamber respectively. A discharge pipe 6a is installed on the upper part of the housing 1 and installed at the outlet end of the discharge pump 6. A controller 13 is installed on the other side of the housing 1. The output end of the controller 13 is electrically connected to the input end of the push-pull electric push rod 11, the drive motor 8, the conveying pump 4 and the discharge pump 6.

[0029] Furthermore, the minimum distance between the rotation radius of the stirring blade 7b and the baffle plate 9b is set to be more than 1.5 times the length of the stirring blade 7b. This setting ensures that the stirring blade 7b will not contact the baffle plate 9b when rotating, while the baffle plate 9b can effectively block the rotational flow of the absorbent liquid driven by the stirring blade 7b.

[0030] Furthermore, all three baffles 9b are set at an angle of 60°. This setting allows the baffles 9b to use their angle to block the rotating absorbent liquid while guiding the absorbent liquid to flow downwards.

[0031] Using the above structure, the controller 13 controls the start of the drive motor 8. One shaft 7 rotates under the drive of the main pulley group 8a, while the secondary pulley group 7a drives the other shaft 7 to rotate, so that the two shafts 7 rotate synchronously. The shafts 7 drive the stirring blades 7b to rotate, and the stirring blades 7b stir the absorbent liquid in the primary absorption chamber and the secondary absorption chamber in the housing 1. The air inlet pipe 3 delivers the exhaust gas to the primary dispersion plate 3a. The exhaust gas emerges from the absorbent liquid in the primary absorption chamber. The rotating absorbent liquid drives the exhaust gas bubbles to rotate. The extension or retraction of the push-pull electric push rod 11 is controlled. The linkage plate 10 and linkage frame 9 move synchronously. The linkage frame 9 drives three sets of lifting shafts 9a to slide on the sealing cover 2. The lifting shafts 9a drive the baffle plate 9b to block the rotating absorbent liquid, so that the waste bubbles in the absorbent liquid are blocked by the baffle plate 9b and flow downward, thereby prolonging the residence time of the waste bubbles in the absorbent liquid. At the same time, the waste gas coming out of the primary absorption chamber is extracted by the conveying and extraction pump 4 and transported to the secondary absorption chamber, where it is fully mixed and absorbed with the rotating absorbent liquid again. This design improves the absorption effect of waste gas and facilitates the replacement of absorbent liquid in the later stage, realizing recycling.
