Description

Technical Field

[0001] This utility model relates to the field of exhaust gas filtration equipment, and in particular to an asphalt fume treatment device for road construction. Background Technology

[0002] Currently, asphalt is a high-viscosity organic liquid with good waterproof and moisture-proof properties, so it is often used for road paving. Since asphalt solidifies at room temperature, it needs to be continuously heated to keep it liquid in order not to affect the road paving. However, asphalt produces a large amount of toxic asphalt fumes during the heating process, which has a high carcinogenic rate. Therefore, asphalt fume treatment devices are needed to treat and purify the toxic fumes during highway construction. The application "An Asphalt Fume Treatment Device for Highway Construction" with application number 202321650092.9 discloses that the sealing cover and filter box can be fixed or disassembled by the interaction of the positioning rod and the positioning hole. The operator only needs to turn the rotating handle in different directions to move the positioning rod into or out of the positioning hole, which facilitates the disassembly and assembly of the sealing cover and filter box, and makes it easy to take out the filter cotton frame inside the filter box for cleaning or replacement.

[0003] The following problems currently exist;

[0004] Because filter cotton can only filter asphalt exhaust gas within certain limits, when its filtration capacity exceeds the limit of the filter cotton itself, its internal filter pores will be blocked by large particles in the flue gas and thus lose their filtering effect. Therefore, the above-mentioned patent does not have an early warning mechanism for replacing the filter cotton, and the replacement time of the filter cotton can only be judged manually by the running time. This results in the filter cotton's usage efficiency being unstable. When the filter cotton is not replaced for a long time, the treatment equipment will lose its filtering effect.

[0025] Example 1

[0026] Reference Figures 1 to 6 This embodiment provides a road construction asphalt fume treatment device, including a filter duct 100. A filter channel 101 is formed through the outer wall of the filter duct 100. The filter channel 101 has a square cross-section. A first storage chamber 102 and a second storage chamber 103 are respectively formed on both sides of the filter channel 101 inside the filter duct 100. An operating chamber 104 is formed on the other side of the filter channel 101 inside the filter duct 100. Two sets of first windows 103a are formed on the inner wall of the operating chamber 104. The operating chamber 104 is connected to the first storage chamber 102 and the second storage chamber 103 through the two sets of first windows 103a. A second window 103b is formed on the inner wall of the operating chamber 104. The operating chamber 104 is connected to the filter channel 101 through the second window 103b. The inner wall of the filter channel 101 has openings at both ends. The third window 103c connects the filter duct 101 to the first storage chamber 102 and the second storage chamber 103 via two sets of third windows 103c. The feeding mechanism 200 includes a first support plate 201, a second support plate 202, a connecting baffle 203, and a sliding plate 204. The first support plate 201 and the second support plate 202 are slidably connected inside the operating chamber 104. The sliding plate 204 is slidably connected inside the filter duct 101. The first support plate 201 and the second support plate 202 are fixedly connected to the outer wall of the sliding plate 204. There are two sets of connecting baffles 203. Both sets of connecting baffles 203 are fixedly connected to the first support plate 201 and the second support plate 202. The two sets of connecting baffles 203 are slidably connected inside the first storage chamber 102 and the second storage chamber 103.

[0027] A limit baffle 104a is installed inside the operating chamber 104. A limit rod 104b is fixedly connected to the top of the limit baffle 104a. A through hole 201a is opened through the top of the outer wall of the first support plate 201. The limit rod 104b passes through the through hole 201a. A limit rod 104b is set on the top of the operating chamber 104. The other end of the limit rod 104b is fixedly connected to the bottom of the outer wall of the first support plate 201. Since both sets of connecting baffles 203 and sliding plates 204 are fixedly connected to the first support plate 201 and the second support plate 202, when the weight of the connecting baffle 203 changes, the entire feeding mechanism 200 will move downward along the limit rod 104b under the support of the support spring 104c.

[0028] An infrared transmitter 105 is installed on the top of the inner wall of the operating chamber 104, and an infrared receiver 202a is installed on the top of the outer wall of the second support plate 202. The infrared transmitter 105 and the infrared receiver 202a are positioned correspondingly. The infrared transmitter 105 emits infrared rays and receives them through the infrared receiver 202a. The distance between the second support plate 202 and the top of the operating chamber 104 is determined by this method, and the overall weight of the feeding mechanism 200 is determined by this distance.

[0029] A servo motor 203a is fixedly connected to one end of the outer wall of the connecting baffle 203. A winding rod 203b is connected to the output end of the servo motor 203a. A positioning rod 203c is rotatably connected to the outer wall of the connecting baffle 203 above the servo motor 203a. An outlet groove 204a is opened through both opposite ends of the outer wall of the slide plate 204. The two sets of servo motors 203a respectively cause the two sets of winding rods 203b to wind up the same roll of filter cotton. One end of the filter cotton is fixed to the outer wall of one set of winding rods 203b. Supported by the positioning rod 203c, it passes through the third window 103c and the outlet groove 204a in sequence until it reaches the other set of positioning rods 203c. The other end is released by the other set of winding rods 203b.

[0030] A glass door 106 is rotatably connected to the outer wall of the filter duct 100. The glass door 106 is supported by glass. When the roll of filter cotton is used up, the filter duct 101, the first storage chamber 102 and the second storage chamber 103 can be opened through the glass door 106 to replace the filter cotton.

[0031] Furthermore, during the movable process of the feeding mechanism 200, the two sets of connecting baffles 203 always fully cover the first window 103a, the slide plate 204 always fully covers the second window 103b and the operating chamber 104, and the outlet trough 204a always overlaps with the third window 103c. Moreover, the outer walls of the two sets of connecting baffles 203 and the slide plate 204 are tightly fitted to the inner walls of their respective chambers, and their edges are all provided with airtight treatment.

[0032] The feeding mechanism 200 includes a control module and a communication module. The control module is electrically connected to the servo motor 203a, and the communication module is electrically connected to the infrared receiver 202a. The distance data information measured by the infrared receiver 202a is transmitted to the control module through the communication module. The control module controls the operation of the servo motor 203a, thereby realizing the winding of the roll of filter cotton by the two sets of servo motors 203a according to the weight change of the feeding mechanism 200 itself.

[0033] Working principle: The two ends of the rolled filter cotton are fixed to two sets of winding rods 203b, and supported by the two sets of winding rods 203b, it passes through the third window 103c and the outlet groove 204a in sequence. In the working state, when the asphalt exhaust gas flows inside the filter duct 101, it is filtered by the filter cotton inside the filter duct 101. As this section of filter cotton continues to filter, large particles will block the pores of the filter cotton, and the weight of this section of filter cotton will increase. Due to the increased weight of this section of filter cotton, the feeding mechanism 200... As the overall weight increases, when the feeding mechanism 200 moves down to a certain threshold at this stage, the control module will control two sets of servo motors 203a to wind up the filter cotton that has lost its filtering function. This will wind up the filter cotton that has lost its filtering function at one set of servo motors 203a and place the new filter cotton at the other end inside the filter duct 101 to filter the asphalt exhaust gas. In this way, the usage status of the filter cotton can be warned, and the servo motor 203a can be used to wind up the filter cotton based on the warning information, thereby completing the purpose of replacing the filter cotton.

[0034] Among them, the infrared transmitter 105, infrared receiver 202a, servo motor 203a, control module and communication module are all common existing technologies in real life, so their structure, principle and power supply will not be described in detail here.
