Description

Technical Field

[0001] The utility model relates to the technical field of straw drainage board production equipment, in particular to a smoke exhaust device for straw drainage board production. Background Art

[0002] Drainage boards are used for drainage of structures in civil construction. The drainage boards and geotextiles are combined into a drainage system, which can form a system with water infiltration, water storage and drainage functions in the structure. Existing drainage boards are usually made of plastic. In order to reduce environmental pollution, the process of making drainage boards with straw as raw material began to appear.

[0003] However, in the production process of existing straw drainage boards, some degradable materials and viscose are usually mixed with straw after being crushed and heated, and a large amount of harmful smoke is generated in the process. In addition, since the straw and viscose are in a relatively closed state when heated and mixed, the generated smoke cannot be discharged from the mixing area in time, causing the smoke to easily escape from the discharge port after the straw is mixed and be inhaled by the surrounding staff, which is more likely to cause certain damage to the health of the staff; in addition, the emitted smoke is also likely to interfere with the staff's vision, which is not conducive to the staff's operation at the discharge port. At the same time, the untreated harmful smoke directly escaping from the equipment is likely to cause pollution to the surrounding environment. Utility Model Content

[0004] Therefore, the purpose of the present utility model is to provide a smoke exhaust device for the production of straw drainage boards to solve the problems raised in the above-mentioned background technology.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figures 1 to 4 As shown, the smoke exhaust device for straw drainage board production in this embodiment includes a base frame 17, a mixing drum 2 is fixedly connected to the top of the base frame 17, an electric heater 16 is fixedly installed on one side of the inner wall of the mixing drum 2, a rotating motor 12 is fixedly installed on one side of the top of the base frame 17, a rotating shaft 11 is engaged with the output end of the rotating motor 12, a reamer 13 is fixedly connected to the outer wall of the rotating shaft 11, a feed hopper 1 is penetrated through the top of the mixing drum 2, a suction pipe 3 is penetrated through the outer wall of the mixing drum 2, and a bottom barrel 4 is sleeved on the bottom end of the suction pipe 3;

[0025] A fan 6 is fixedly installed on one side wall of the bottom cylinder 4, a filter screen 22 is engaged with the intersection of the air inlet of the fan 6 and the bottom cylinder 4, a connecting pipe 7 is sleeved on the air outlet of the fan 6, a sleeve 8 is sleeved on the bottom end of the connecting pipe 7, a filter cartridge 14 is engaged inside the sleeve 8, an exhaust pipe 9 is penetrated through the bottom end of the sleeve 8, a spring 18 is provided on the top of the inner side of the suction pipe 3, a sliding frame 19 is fixedly connected to the bottom end of the spring 18, a pull rope 20 is fixedly connected to the middle part of the sliding frame 19, a side door panel 10 is hinged on the front of the mixing drum 2, and a discharge hopper 15 is penetrated through the bottom end of the mixing drum 2.

[0026] Specifically, the base frame 17 is a horizontal supporting structure, which can support and fix the mixing drum 2. The mixing drum 2 can achieve the mixing of crushed straw, viscose and some degradable materials. The suction pipe 3 is located near the top of the mixing drum 2, so that the smoke generated in the mixing drum 2 can be sucked in by the suction pipe 3 in time when it floats upward. The bottom drum 4 serves as a buffer structure at the connection between the fan 6 and the suction pipe 3, which can make the particulate matter sucked into the suction pipe 3 with the smoke settle and be collected in the suction box 5, thereby reducing the particulate matter from entering the fan 6 and interfering with the rotation of the fan 6. The fan 6 can draw the suction pipe 3 into a negative pressure state, so that the smoke near the suction pipe 3 mouth can be quickly sucked in, thereby achieving the timely suction of the smoke generated in the mixing drum 2 and reducing the probability of the smoke escaping from the discharge port of the discharge hopper 15. The mesh number of the filter 22 is 200 meshes, so that the inhaled particulate matter in the suction pipe 3 can be intercepted in The smoke that has completed the particle filtration enters the sleeve 8 through the connecting pipe 7. The filter cartridge 14 contains filtering materials such as activated carbon, which can purify the smoke, so that the smoke discharged through the device is not easy to pollute the environment, and will not cause harm to the health of the staff. The outer wall of the sliding frame 19 fits with the inner wall of the suction pipe 3, so that when the sliding frame 19 slides up and down in the suction pipe 3, the particles adhering to the inner wall of the suction pipe 3 can be scraped off, reducing the probability of the suction pipe 3 being blocked by particles such as cigarette ash. The sliding frame 19 slides up and down in the suction pipe 3 by means of the spring 18 and the pull rope 20. The pull rope 20 is a wear-resistant and corrosion-resistant steel wire rope. The initial state of the side door panel 10 is a closed state, so that the mixing drum 2 can be in a relatively closed state when smoke is generated, and when the mixing drum 2 is not in use, the mixing drum 2 can be opened, which is convenient for cleaning the inside of the mixing drum 2.

[0027] Furthermore, the interior of the suction pipe 3 is connected to the interior of the mixing drum 2, and the interior of the suction pipe 3 is connected to the interior of the bottom drum 4. The suction pipe 3 can suck the smoke generated inside the mixing drum 2 via the negative pressure generated by the fan 6, so that the smoke is promptly drawn out of the mixing drum 2 and enters the bottom drum 4, thereby reducing the probability of the smoke in the mixing drum 2 escaping from the discharge hopper 15 and reducing the probability of the staff at the discharge hopper 15 inhaling the smoke.

[0028] Furthermore, a suction box 5 is movably embedded inside the bottom tube 4, and an opening is opened at the top of the suction box 5. The opening of the suction box 5 faces upward, and can receive particulate matter that is sucked in from the suction pipe 3 along with the smoke, so that the particulate matter descends along the suction pipe 3 and falls into the suction box 5, and cooperates with the filter 22 to achieve preliminary filtration of the smoke.

[0029] Furthermore, the top end of the spring 18 is fixedly connected to the top of the inner side of the suction tube 3, and the sliding frame 19 is movably embedded in the suction tube 3 through the spring 18. When the spring 18 is in the initial state, the sliding frame 19 is located at the top of the inner side of the suction tube 3 and remains stationary, and the side door panel 10 is also in a closed state.

[0030] Furthermore, a transverse tube 21 is fixedly connected to the inner wall of the mixing drum 2, and the pull rope 20 is movably connected and interlaced with the transverse tube 21. The pull rope 20 can slide in the transverse tube 21 when being pulled, so that the pull rope 20 is not easy to contact with the reamer 13 in the mixing drum 2 and raw materials such as straw, thereby protecting the pull rope 20.

[0031] Furthermore, the bottom end of the pull rope 20 is fixedly connected to the inner wall of the side door panel 10, and the pull rope 20 is movably connected to the mixing drum 2 through the side door panel 10. When the side door panel 10 is opened, the pull rope 20 will be subjected to a downward pulling force to pull the sliding frame 19, so that the sliding frame 19 slides down along the inner wall of the suction pipe 3. At the same time, the sliding frame 19 also stretches the spring 18. When the side door panel 10 is closed, the stretched spring 18 will drive the sliding frame 19 to return to its original position.

[0032] Furthermore, the connecting pipe 7 is connected to the interior of the exhaust pipe 9 through the sleeve 8, and the flue gas entering the connecting pipe 7 can enter the exhaust pipe 9 along the sleeve 8, so that the flue gas purified in the sleeve 8 can be smoothly discharged out of the device.

[0033] The method of using the present embodiment is as follows: when using the smoke exhaust device for producing straw drainage boards, the device can be installed at a suitable position first, and then an external power supply can be connected. When the rotating motor 12 is started, the rotating shaft 11 will drive the reamer 13 to rotate in the mixing drum 2 to mix and stir the straw, viscose and degradable materials entering from the feed hopper 1. At the same time, the electric heater 16 will heat the mixing drum 2. As the temperature rises, smoke will be generated in the mixing drum 2. At this time, the fan 6 is started so that the fan 6 sucks the smoke in the mixing drum 2 into the suction pipe 3 through the suction pipe 3, and then enters the bottom drum 4 along the suction pipe 3. At this time, the particulate matter entering the suction pipe 3 with the smoke will be intercepted by the filter screen 22, and then fall into the suction box 5 of the bottom drum 4, and the smoke is sucked into the fan 6 and then discharged to the exhaust port of the fan 6. The smoke is then filtered out from the exhaust pipe 9. When the device is not started, the side door panel 10 on the front of the mixing drum 2 can be opened, so that the side door panel 10 drives the pull rope 20 to slide along the horizontal pipe 21. At the same time, the slide frame 19 in the suction pipe 3 is pulled downward, so that the slide frame 19 slides down along the inner wall of the suction pipe 3, and the particles adhering to the inner wall of the suction pipe 3 are scraped, so that the particles on the inner wall of the suction pipe 3 fall into the mixing drum 2. At the same time, the slide frame 19 also stretches the spring 18, and then the mixing drum 2 can be cleaned through the opening formed by opening the side door panel 10. After the cleaning is completed, the side door panel 10 is closed, and the slide frame 19 brings the stretched spring 18 back into the suction pipe 3.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
