Therefore, injection molding machines need waste gas treatment equipment to collect and treat the harmful waste gases generated during the injection molding process to reduce their impact on the environment and human body.

[0003] Most of the existing waste gas treatment equipment for injection molding machines may cause unnecessary damage to the equipment during use due to the high temperature of the waste gas. In addition, when the waste gas enters the filter layer, it cannot have more contact time with the filter layer, thereby reducing the purification effect. Most of the existing waste gas treatment equipment for injection molding machines is not convenient for disassembly and assembly when cleaning the filter. Therefore, technical improvements are needed.

[0004] Therefore, those skilled in the art have provided an exhaust gas treatment device for an injection molding machine to solve the problems raised in the above background technology. Utility Model Content

Because the buffer tube is arranged as a plurality of curved pipes, the waste gas is subjected to greater resistance during the flow process, so that the flow rate becomes slow after going out of the buffer tube, so that the waste gas can be in contact with the filter layer for a longer time, thereby improving the effect of purifying the waste gas.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] Furthermore, an exhaust pipe is fixedly connected to the upper surface of the box.

[0012] Furthermore, a hinge rotating device is provided on one side of the front end outer wall of the box body, and the box body and the box door are rotatably connected through the hinge rotating device.

[0013] Through the above technical solution, the box door can be rotated on the box body through the hinge rotating device, thereby opening and closing the box door.

[0014] Furthermore, a water inlet pipe is provided in the middle of the outer wall of one side of the box body.

[0022] Furthermore, the iron block is snap-connected to the limiting groove.

[0023] With the above technical solution, the iron block and the limiting groove can be more closely fitted through the snap connection, thereby increasing the sealing performance.

[0024] The utility model has the following beneficial effects:

[0025] 1. The waste gas treatment equipment for injection molding machines proposed by the utility model is compared with most existing waste gas treatment equipment for injection molding machines. The waste gas treatment equipment uses a sealing block to first rotate the sealing block to a vertical position, so that the pressure on the box door disappears, and then the power is turned off to make the electromagnet lose its magnetic force, so that the iron block on the box door separates the electromagnet, thereby realizing the opening of the box door, and then sliding the iron filter out of the filter groove inside the engaging block on the box door, thereby realizing more convenient cleaning of the iron filter. When the box door is closed, the electromagnet is energized to generate suction with the iron block on the box door, and then the sealing block is pulled to the positioning groove and rotated to a horizontal position so that it is stuck in the positioning groove. The movement of the sealing block drives the sliding block to move outward, thereby compressing the spring. At this time, the spring starts to react due to compression, so that the sealing block is squeezed, thereby making the sealing between the box door and the box body better.

[0026] 2. Compared with most existing waste gas treatment equipment for injection molding machines, the waste gas treatment equipment proposed in the utility model uses an air suction hood and an air pump to allow the waste gas to enter the water cavity through the air suction pipe and come into contact with the water in the water cavity, so that the temperature of the waste gas can be reduced, thereby avoiding damage to the equipment caused by excessively high waste gas temperature. The waste gas then enters the buffer tube through water bubbles. Because the buffer tube is provided with multiple curved tubes, the waste gas is subjected to greater resistance during the flow process, so that the flow rate becomes slow after leaving the buffer tube, so that the waste gas can be in contact with the filter layer for a longer time, thereby improving the effect of purifying the waste gas.

[0037] An air pump 12 is fixedly connected to the lower end of the outer wall of one side of the box body 1, an air pump 12 is fixedly connected to the input end of the air pump 12, and an air suction hood 9 is fixedly connected to the side of the air suction pipe 10 away from the air pump 12. A water cavity 28 is opened at the lower end of the interior of the box body 1, a buffer tube 19 is provided at the upper end of the water cavity 28, a fiber filter screen 17 is provided at the upper end of the iron filter screen 18, and an activated carbon net 16 is provided at the upper end of the fiber filter screen 17.

[0038] This type of waste gas treatment equipment for injection molding machines is easier to disassemble and clean, can cool the waste gas, and allows the filter layer to be more fully in contact with the waste gas treatment.

[0039] An exhaust pipe 2 is fixedly connected to the upper surface of the box body 1, through which the purified gas can be discharged from the box body 1. A hinge rotating device 25 is provided on one side of the outer wall of the front end of the box body 1. The box body 1 and the box door 27 are rotatably connected through the hinge rotating device 25. The box door 27 can be rotated on the box body 1 through the hinge rotating device 25, thereby opening and closing the box door 27. A water inlet pipe 14 is provided in the middle of the outer wall of one side of the box body 1. The water in the water cavity 28 can be replenished through the water inlet pipe 14. The lower end of the outer wall of one side of the box body 1 is provided with a water inlet pipe 14. A water outlet pipe 15 is provided, through which water and impurities in the water cavity 28 can be discharged. A base 8 is fixedly connected to the lower surface of the box body 1, and the base 8 can provide better support for the waste gas treatment equipment for the injection molding machine. The sealing block 13 and the positioning groove 6 are connected by a snap connection, which can make the sealing block 13 fit more closely with the positioning groove 6 through the snap connection, thereby better bearing force. The iron block 5 and the limiting groove 26 are connected by a snap connection, which can make the iron block 5 fit more closely with the limiting groove 26 through the snap connection, thereby increasing the sealing performance.

[0040] Working principle: During use, when the air pump 12 is turned on, the exhaust gas enters the suction pipe 10 through the suction hood 9, thereby allowing the exhaust gas to enter the water chamber 28 and come into contact with the water in the water chamber 28, thereby reducing the temperature of the exhaust gas, thereby avoiding damage to the equipment caused by excessively high exhaust temperature, and then enters the buffer tube 19 through water bubbles. Because the buffer tube 19 is configured as a plurality of curved tubes, the exhaust gas is subjected to greater resistance during the flow process, so that the flow rate becomes slow after exiting the buffer tube 19, thereby allowing the exhaust gas to contact the filter layer for a longer time, thereby improving the effect of purifying the exhaust gas. When the box door 27 is closed, by energizing the electromagnet 3, suction is generated with the iron block 5 on the box door 27, and then by pulling the sealing block 13 to the positioning groove 6 and rotating it to the water through the rotating block 21. The horizontal position makes it stuck in the positioning groove 6, and the sealing block 13 moves, so that the connecting block 22 drives the sliding block 23 to move outward, thereby compressing the spring 20. At this time, the spring 20 starts to react due to compression, so that the sealing block 13 is forced to squeeze with the positioning groove 6, thereby making the sealing of the box door 27 and the box body 1 better. When it is necessary to clean the iron filter 18, first rotate the sealing block 13 to a vertical position by rotating the block 21, so that the pressure on the box door 27 disappears, and then cut off the power to make the electromagnet 3 lose its magnetic force, so that the iron block 5 on the box door 27 separates the electromagnet 3, so that the box door 27 is opened by the hinge rotating device 25, and then slides out the iron filter 18 through the filter groove 4 inside the engaging block 7 on the box door 27, thereby making it more convenient to clean the iron filter 18.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
