Description

Technical Field

[0001] The utility model relates to the technical field of toughener production, and particularly relates to an exhaust gas treatment device in the production process of a toughener. Background Technique

[0002] A toughener is a substance that can increase the flexibility of the adhesive film layer, mainly used to improve the brittleness of some thermosetting resin adhesives after curing and increase their bearing strength. During the production process of the toughener, waste gas will be generated. Direct emission will pollute the surrounding air, so a special waste gas treatment device is needed to treat the waste gas to meet the emission standards, which is an important device to ensure the safety of the production environment and reduce environmental pollution.

[0003] The existing technical solutions in the traditional ones have the following defects:

[0004] 1. The gas collected into the device usually directly rushes towards the outlet, and the residence time when passing through the spray water is not sufficient, and the harmful substances in the waste gas cannot be fully absorbed or reacted by the spray water, resulting in a still relatively high emission concentration of the waste gas after treatment and unable to meet the environmental protection emission standards;

[0005] 2. When collecting the waste gas, it needs to be connected through pipes, but the usual pipe connection is relatively simple and the sealing effect is poor. Waste gas leakage occurs during the collection process of the gas, increasing the risk of air pollution. These waste gases contain harmful substances, posing a threat to the environment and human health. Content of the Utility Model

[0006] The purpose of the utility model is to provide an exhaust gas treatment device in the production process of a toughener, so as to solve the defects of poor treatment effect and poor sealing performance of the existing exhaust gas treatment device in the production process of a toughener.

[0007] To solve the above technical problems, the utility model provides the following technical solution: an exhaust gas treatment device in the production process of a toughener, including a housing and a filtering structure; a filtering structure is arranged inside the housing, an adjusting mechanism is arranged at the bottom end inside the housing, and the bottom end of the housing at the bottom of the adjusting mechanism is connected with a collecting pipe, and one end of the bottom of the housing is connected with a box body; the adjusting mechanism includes a fan blade, a connecting shaft, a connecting rod and a servo motor; the fan blade is arranged at the bottom of the housing, connecting shafts are fixed at the outer ends of the fan blade, and connecting rods are hinged between the connecting shafts, and a servo motor is installed at one end of the connecting shaft.

[0009] Preferably, a convex block is fixed to the top end of the limit block, and a sealing ring is fixed to the bottom end of the housing at the top of the convex block. The sleeve is provided with an external thread, and the sleeve is threadedly connected to the housing.

[0010] Preferably, the box body includes a water outlet pipe, a filter screen, and a zeolite filter screen. The water outlet pipe is connected to the bottom end of the housing. A filter screen is installed inside the box body at the end of the water outlet pipe, and a zeolite filter screen is installed at the bottom end of the filter screen. A sliding structure is formed between the filter screen and the box body, and a sliding structure is formed between the zeolite filter screen and the box body.

[0011] Preferably, the filtering structure includes a polypropylene filter screen, an activated carbon filter screen, a water inlet pipe, and a spray head. The water inlet pipe is arranged inside the housing, and three spray heads are installed at the bottom end of the water inlet pipe.

[0012] Preferably, an activated carbon filter screen is fixed inside the housing at the bottom end of the water inlet pipe, and a polypropylene filter screen is fixed inside the housing at the top end of the activated carbon filter screen.

[0013] Preferably, a plurality of groups of fan blades are provided, and a rotating structure is formed between the fan blades and the housing. The fan blades can be spliced into a circular shape after being flipped.

[0014] An exhaust gas treatment device in the production process of a toughening agent provided by the present invention has the following advantages: By providing an adjustment mechanism, when the exhaust gas enters the housing from the collection pipe, it passes through the fan blades. The servo motor can be started to drive the connecting shaft to rotate, so that the fixedly connected fan blades rotate. The fan blades are hinged and fixed by connecting rods, driving all the fan blades to rotate simultaneously. Adjust according to the required wind speed and direction, so that the exhaust gas spirally rises when passing through, increasing the residence time of the exhaust gas and fully contacting with the sprayed water, thereby enhancing the treatment effect of the exhaust gas treatment device in the production process of the toughening agent. The harmful substances in the exhaust gas are fully absorbed or reacted by the sprayed water, improving the treatment efficiency.

[0015] By providing a collection pipe, when the collection pipe is connected to the housing, the limit block is aligned with the air inlet at the bottom of the housing, so that the convex block presses the sealing ring, and then the sleeve is rotated and connected to the bottom of the housing. The fixing is achieved through the threaded cooperation between the sleeve and the housing. While continuously tightening, the convex block continuously presses the sealing ring. The sealing ring is an "O" - shaped ring, which fully fills the groove at the connection, strengthening the sealing effect. Thus, the sealing effect of the exhaust gas treatment device in the production process of the toughening agent is improved, avoiding the phenomenon of exhaust gas leakage and reducing the risk of air pollution.
