Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fabric gilding, in particular to an exhaust gas treatment mechanism for fabric gilding. Background Art
[0002] A gilding machine is a process processing device that uses high temperature and high pressure to stamp aluminum foil on decorative fabrics. By stamping metallic luster printing patterns on decorative fabrics with a gilding machine, it can maintain relatively bright colors and is not easy to fade, and the texture after stamping is not easy to wear, which is convenient for long-term storage and transportation, and is beneficial to improving the aesthetics and practicality of the production of decorative fabrics.
[0003] When gilding fabrics, high temperature will cause the moisture and other substances in the fabric to evaporate, thus generating exhaust gas. For this reason, a blower is used to absorb the exhaust gas, and after filtering, it is discharged. Generally, the gas delivery pipe is directly connected or connected to the air inlet and outlet of the blower through a short and straight pipe joint. After the gas is inhaled, filtered and discharged, its temperature is still relatively high, which will affect the physical health of workers and the quality of products. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an exhaust gas treatment mechanism for fabric gilding, which has the advantage of being able to reduce the temperature of the gas discharged after filtering.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions:
[0006] An exhaust gas treatment mechanism for fabric gilding includes a gilding mechanism. A frame is arranged around the gilding mechanism. A wind box is fixedly connected below the top of the frame of the gilding mechanism. A filtering mechanism is arranged inside the wind box. A blower is fixedly connected to the side of the top of the frame. A metal pipe interface one and a pipe interface two are respectively fixedly connected to the air inlet and outlet of the blower. The two pipe interfaces are respectively fixedly connected to the wind box through a delivery pipe. The pipe interface one is relatively long and is L-shaped. The middle of the pipe interface two is wide and both ends are narrow, and its cross-section is hexagonal. The pipe interface two is relatively long and is respectively connected to the air outlet of the blower and the delivery pipe at both ends.
[0007] With the above technical solution, the fan sucks the waste gas into the delivery pipe at the air inlet through the air box, and the waste gas flows into the first L-shaped pipe interface from the delivery pipe. Since the length of the first pipe interface is relatively long, the waste gas stays inside for a longer time, and the heat of the waste gas will be slowly absorbed by the first pipe interface and then dissipated into the air. After the waste gas is cooled to a certain extent in the first pipe interface, it enters the second pipe interface. The distance between the upper and lower bottom surfaces of the second pipe interface is relatively large, so the flow rate of the waste gas increases while the flow velocity decreases. The length of the second pipe interface is relatively long, so the time for the waste gas to flow through the second pipe interface increases, thereby increasing the time for heat transfer between the second pipe interface and the waste gas, further reducing the heat of the waste gas. The cooled gas enters the air box again, and after being filtered by the air box, it is discharged, reducing part of the heat in the gas and the harm caused to workers and products after discharge.
[0008] Preferably, the delivery pipe is a flexible telescopic hose.
[0009] With the above technical solution, the vibration generated during the operation of the fan can be absorbed, reducing the impact of equipment vibration on the pipeline.
[0010] Preferably, two rows of ventilation openings are provided on the bottom surface of the air box. A vertical partition is fixedly connected inside the air box. The partition is located in the middle of the air box and divides the air box into two chambers. The two rows of ventilation openings are respectively located on the bottom surfaces of the two chambers. The two chambers are connected to the air inlet and outlet of the fan through the delivery pipe. A filter element is provided in the chamber connected to the air outlet. The two sides of the filter element are respectively fixedly connected to the inner wall of the air box and the partition.
[0011] With the above technical solution, the fan sucks the waste gas into the chamber connected to the air inlet, then flows out of the chamber, and after being cooled, it flows into another chamber inside the air box and is discharged after being filtered by the filter element in the chamber.

[0017] The following is only the preferred embodiment of the present utility model, and the protection scope is not limited to this embodiment. Any technical solutions falling within the concept of the present utility model shall belong to the protection scope of the present utility model. At the same time, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
[0018] See Figures 1 to 4 , an exhaust gas treatment mechanism for fabric gilding, comprising a gilding mechanism. A frame 1 is arranged around the gilding mechanism. Below the top of the frame 1 of the gilding mechanism, an air box 2 is fixedly connected. Two rows of ventilation openings 7 are formed in the bottom surface of the air box 2. A vertical partition 8 is fixedly connected inside the air box 2. The partition 8 is located in the middle of the air box 2 and divides the air box 2 into two chambers. The two rows of ventilation openings 7 are respectively located at the bottom surfaces of the two chambers. A filter element 9 is arranged in one of the chambers. The two sides of the filter element 9 are respectively fixedly connected with the inner wall of the air box 2 and the partition 8. A blower 3 is fixedly connected to the side of the top of the frame 1. The air inlet and the air outlet of the blower 3 are respectively fixedly connected with a metal pipe interface one 4 and a pipe interface two 5. The pipe interface one 4 is relatively long and is L-shaped. The pipe interface two 5 has a larger diameter. The middle of the pipe interface two 5 is wide at both ends and narrow in the middle, and its cross-section is hexagonal, and the pipe interface two 5 is relatively long. The pipe interface two 5 is connected to the chamber where the filter element 9 is arranged through a conveying pipe 6, and the pipe interface one 4 is connected to the other chamber.
[0019] Working principle: The blower 3 sucks the exhaust gas into the chamber connected to the air inlet, and then the exhaust gas flows from the chamber into the telescopic pipe and then into the L-shaped pipe interface one 4. Since the pipe interface one 4 is relatively long, the exhaust gas flows inside it for a longer time, and the heat of the exhaust gas will be slowly absorbed by the pipe interface one 4 and then dissipated into the air. After the exhaust gas is cooled to a certain extent in the pipe interface one 4, it enters the pipe interface two 5. The distance between the upper and lower bottom surfaces of the pipe interface two 5 is relatively large, so the flow rate of the exhaust gas increases and the flow velocity of the exhaust gas decreases. The pipe interface two 5 is relatively long, so the time for the exhaust gas to flow through the pipe interface two 5 increases, thereby increasing the time for heat transfer between the pipe interface two 5 and the exhaust gas and further reducing the heat of the exhaust gas. The cooled gas then flows into the other chamber inside the air box 2 again, and after being filtered by the filter element 9 in the chamber, it is discharged, reducing part of the heat in the gas and reducing the harm caused to workers and products after its discharge.
