Description

Technical Field

[0001] The invention relates to the technical field of paint treatment, in particular to a device for treating waste gas of paint. Background Art

[0002] In the field of industrial production, especially in paint-related industries such as automobile manufacturing, furniture painting, and mechanical processing, paint is widely used. During the coating process, paint will volatilize a large amount of organic waste gas, which contains a variety of harmful substances, such as benzene, toluene, xylene, volatile organic compounds (VOCs), etc. With the continuous expansion of industrial scale and the continuous increase in the use of paint, the emission of waste gas and paint waste gas is also increasing, becoming one of the important sources of air pollution.

[0003] At present, for the treatment of waste gas and paint waste gas, such as the publication number CN212417453U, a paint waste gas treatment device is disclosed, including a support plate, the upper surface of the support plate is fixedly connected with a treatment box and a water tank, the upper surface of the treatment box is provided with a threaded hole, and the hole wall of the threaded hole is threadedly connected with a sealing plug, the outer wall of the treatment box is fixedly connected with a blower, the output end of the blower is fixedly connected with a conduit, the bottom end of the conduit passes through the upper surface of the treatment box and extends downward, the upper surface of the treatment box is fixedly connected with a connecting pipe, the bottom end of the connecting pipe passes through the upper surface of the water tank and extends downward, and the side wall of the water tank is fixedly connected with an auxiliary mechanism. The utility model can effectively treat waste gas in paint construction, avoid waste gas polluting the surrounding environment, ensure environmental protection requirements in paint construction, and at the same time improve the safety of paint construction, and can ensure the physical health of workers in paint construction.

[0004] During the use of the above-mentioned device, the staff is required to separately control the formaldehyde addition solution and the exhaust mechanism. In the process of adding the solution, the staff needs to rely on their own experience to judge the dosage to be added, which may easily lead to excessive or insufficient addition. If too much is added, it will not only cause waste of chemical reagents and increase processing costs, but also the excess chemicals may produce new pollutants in subsequent treatments, increasing the difficulty of treatment. If too little is added, it will not be able to fully react with the harmful substances in the exhaust gas, and it is difficult to achieve the expected treatment effect, resulting in substandard exhaust gas emissions. In addition, the separate control of the formaldehyde addition solution and the exhaust mechanism requires the staff to always pay attention to the operating status of the equipment, which increases labor costs and work intensity, and is not conducive to the automation and continuity of the production process. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a device for treating waste gas and paint waste gas, which solves the problem that when the above-mentioned device is in use, the staff needs to separately control the formaldehyde addition solution and the exhaust mechanism, and the dosage of the added solution is determined by experience, which is prone to over-addition or under-addition. Too much will waste reagents and increase processing costs and difficulty, while too little will make it difficult to achieve the treatment effect, resulting in waste gas emissions not meeting standards. In addition, separate control also increases labor costs and work intensity, which is not conducive to production automation and continuity.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A waste gas and paint waste gas treatment device, comprising a shell, the inner wall of the shell is provided with a storage mechanism, the storage mechanism includes a storage cylinder, the top of the storage cylinder is fixedly connected with a feed pipe, the outer wall of the storage cylinder is fixedly connected with an ultrasonic sensor, the bottom of the shell is hinged with a box door, the top of the shell is provided with an exhaust mechanism, the exhaust mechanism includes a top pipe, the inner wall of the top pipe is fixedly connected with a double-axis motor, one group of output shafts of the double-axis motor is fixedly connected with a fan, the other group of output shafts of the double-axis motor is fixedly connected with a disc, the inner wall of the disc is slidably connected with a protrusion, the outer wall of the disc is fixedly connected with a sliding track, the inner wall of the sliding track is rotatably connected with a threaded rod, the protrusions are provided with multiple groups, the multiple groups of protrusions are connected to each other by a hinge, one end of the hinge is hinged to the outer wall of one group of protrusions, and the other end of the hinge is hinged to the outer wall of another group of protrusions, the top of the storage cylinder is fixedly connected with a reagent tube, and the inner wall of the reagent tube is penetrated and slidably connected with a push rod.

[0007] Preferably, both ends of the storage cylinder are fixedly connected to the inner wall of the shell.

[0008] Preferably, the bottom of the storage cylinder is fixedly connected to an electronic valve, the bottom of the electronic valve is fixedly connected to a discharge cylinder, and the upper and lower ends of the discharge cylinder are fixedly connected to the inner wall of the shell.

[0009] Preferably, the bottom of the top pipe is fixedly connected to the top of the storage cylinder.

[0010] Preferably, a remote control motor is fixedly connected to the bottom of the sliding track, the remote control motor is connected to the ultrasonic sensor, and the output shaft of the remote control motor is fixedly connected to the bottom of the threaded rod.

[0011] Preferably, a slider is threadedly connected to the outer wall of the threaded rod, and the outer wall of the slider is fixedly connected to the outer wall of the protrusion.

[0012] Preferably, a positioning block is hinged at the center of the hinge.

[0013] Preferably, a sliding groove is provided on the inner wall of the disc, and the inner wall of the sliding groove is slidably connected to the outer wall of the positioning block.

[0014] Preferably, an arc block is fixedly connected to the bottom of the push rod, and a sealing ball is fixedly connected to the top of the push rod.

[0015] Preferably, the top of the arc block is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the bottom of the reagent tube.

[0016] Working principle: When the waste paint needs to be treated, the staff needs to first open the feed pipe to transfer the paint to be treated to the inner wall of the storage tube, and start the double-axis motor set on the inner wall of the top tube to drive the fan to rotate, so that the fan generates wind to extract the waste paint gas in the inner wall of the storage tube and discharge it outward along the exhaust pipe;

[0017] At the same time, the output shaft at the other end of the dual-axis motor drives the disc to rotate, so that the disc rotates and the convex block rotates at the same time, so that the outer wall of the convex block squeezes the bottom of the arc block, and the squeezing force drives the push rod to move upward, so that the push rod drives the sealing ball to separate from the bottom of the reagent tube, so that the reagent tube opens, and the formaldehyde treatment agent in the inner wall of the reagent tube is discharged into the inner wall of the storage cylinder, thereby achieving the effect of waste gas treatment of the paint. At the same time, the integrated design allows the exhaust and addition of formaldehyde treatment agent to be carried out at the same time, saving the process of separate control by the staff and further improving work efficiency.

[0018] At the same time, an ultrasonic sensor is arranged on the outer wall of the storage cylinder, so that the ultrasonic sensor can monitor the paint liquid level in the inner wall of the storage cylinder, so as to judge the amount of paint, and control the remote control motor to start according to the amount of paint, so that the remote control motor drives the threaded rod to rotate, so that the threaded rod drives a group of protrusions to move outward, and cooperates with the provided hinges to make the six groups of protrusions move outward at the same time, changing the position of the protrusions on the disc, so that after the protrusions move outward, the extrusion distance of the arc block is larger, and the amount of formaldehyde treatment agent added is larger, which is suitable for use when the amount of paint is large, and after the protrusions move inward, the extrusion distance of the arc block is smaller, and the amount of formaldehyde treatment agent added is smaller, which is suitable for use when the amount of paint is small.

[0019] The present invention provides a device for treating waste gas and paint waste gas. It has the following beneficial effects:

[0020] 1. The present invention can monitor the paint level in real time by setting an ultrasonic sensor on the outer wall of the storage cylinder, so as to accurately determine the amount of paint waste gas. According to the amount of waste gas, the ultrasonic sensor is linked with the remote control motor to intelligently control the rotation of the threaded rod, thereby adjusting the position of the bump. The change of the position of the bump will accurately control the amount of formaldehyde treatment agent extruded by the push rod, avoiding the problem of excessive or insufficient dosage when adding manually based on experience, which not only ensures the waste gas treatment effect, but also avoids reagent waste, reduces the treatment cost, and reduces the new pollutants and treatment difficulty that may be generated due to excessive reagents.

[0021] 2. The present invention provides a hinge so that when one group of protrusions moves outward or inward, the design of the hinge drives multiple groups of protrusions to move simultaneously, making the adjustment process more convenient and faster.

[0022] 3. The present invention adopts an integrated design, so that when the dual-axis motor is working, on the one hand, it drives the fan to extract the paint waste gas and discharge it, and on the other hand, it drives the disc to rotate, and the formaldehyde treatment agent is added by squeezing the push rod through the convex block, so that the exhaust and the addition of the treatment agent are carried out simultaneously. This innovative design saves the cumbersome steps of the staff to control the formaldehyde addition solution and the exhaust mechanism separately, greatly improves the work efficiency, and is also conducive to the automation and continuity of the production process, reducing labor costs and work intensity.
