Description

Technical Field

[0001] This application relates to the field of material toxicity testing technology, and in particular to a toxic smoke detection and flue gas recovery device. Background Technology

[0002] In construction projects, in order to ensure people's safety, the requirements for building materials are extremely high. In addition to having basic sturdiness, the materials also need to be non-toxic. Toxicity testing of building materials requires the use of smoke-producing toxicity testing equipment.

[0003] Currently, with traditional toxic smoke detection devices, after the material is burned, the ash produced during the combustion process falls onto the surface of the placement plate. After the combustion is complete, the ash on the surface of the placement plate needs to be manually cleaned by staff, resulting in a waste of human resources. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a toxic smoke detection and flue gas recovery device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a toxic smoke detection and flue gas recovery device, comprising a base, a combustion furnace fixedly connected to the top of the base, a detection mechanism provided on one side of the combustion furnace, a recovery mechanism provided on the side of the detection mechanism away from the combustion furnace, a protection mechanism provided inside the combustion furnace, a cleaning mechanism provided on one side of the protection mechanism, the cleaning mechanism comprising an electric push rod, the electric push rod fixedly connected to the combustion furnace, a movable plate fixedly connected to the telescopic end of the electric push rod, the movable plate slidably connected to the combustion furnace, a wire brush fixedly connected to the surface of the movable plate, a placement plate slidably connected inside the combustion furnace, a collection box provided at the bottom of the placement plate, and the collection box slidably connected to the combustion furnace.

[0006] In a preferred embodiment, the testing mechanism includes an air pump, which is fixedly connected to a combustion furnace. A delivery pipe is fixedly connected to one side of the air pump, and a testing box is fixedly connected to the side of the delivery pipe away from the air pump. The testing box is fixedly connected to a base, and a sealing door is hinged to the surface of the testing box.

[0007] By adopting the above technical solution, mice are placed inside the testing chamber by opening the sealed door, then the sealed door is closed, and the toxic fumes inside the combustion furnace are drawn into the first delivery pipe. The first delivery pipe then transports the toxic fumes to the inside of the testing chamber, exposing the mice to the fumes environment. Indicators such as respiratory rate and mortality rate are observed, and the toxicity index is calculated. This method can better estimate the toxicity index.

[0008] In a preferred embodiment, the recycling mechanism includes a recycling pump, which is fixedly connected to a detection box. A second conveying pipe is fixedly connected to one side of the recycling pump, and a storage pipe is fixedly connected to the side of the second conveying pipe away from the recycling pump. The storage pipe is fixedly connected to a base.

[0009] By adopting the above technical solution, the residual toxic fumes inside the detection box are drawn into the second conveying pipe by the recovery pump, and then the toxic fumes are transported to the storage pipe by the second conveying pipe, and then the toxic fumes are stored in the storage pipe, which can better recover the toxic fumes.

[0010] In a preferred embodiment, a discharge pipe is fixedly connected to the side of the storage pipe away from the second delivery pipe, and a valve is fixedly connected to the surface of the discharge pipe.

[0011] By adopting the above technical solution, the toxic fumes inside the storage tube can be discharged more effectively by using a valve on the surface of the discharge tube to lock the valve on the discharge tube.

[0012] In a preferred embodiment, an igniter is fixedly connected inside the combustion furnace.

[0013] By adopting the above technical solution, an igniter is fixedly connected inside the combustion furnace, and the igniter ignites the material inside the combustion furnace, which can better ignite the material inside the combustion furnace.

[0014] In a preferred embodiment, a laser particle size analyzer is fixedly connected inside the detection box.

[0015] By adopting the above technical solution, a laser particle size analyzer is fixedly connected inside the detection box. The laser particle size analyzer analyzes the particle size distribution of smoke and dust, and assesses the risk of breathing penetration of ultrafine particles. This allows for a better analysis of the particle size distribution of smoke and dust and an assessment of the risk of breathing penetration of ultrafine particles.

[0016] In a preferred embodiment, the protection mechanism includes a motor, which is fixedly connected to the combustion furnace. A threaded rod is fixedly connected to the output end of the motor. A baffle is threadedly connected to the outer surface of the threaded rod. The baffle is slidably connected to the combustion furnace. A limit rod is slidably connected inside the baffle. The limit rod is fixedly connected to the combustion furnace.

[0017] By adopting the above technical solution, the output end of the motor rotates to drive the threaded rod to rotate, and the rotation of the threaded rod drives the baffle to move. The limit rod then limits the baffle, and the baffle protects the wire brush, thus providing better protection for the wire brush.

[0018] In a preferred embodiment, the interior of the combustion furnace is fixedly connected with a heat insulation layer, which is made of rock wool.

[0019] By adopting the above technical solution, a heat insulation layer is fixedly connected inside the combustion furnace, and the heat insulation performance of the combustion furnace is enhanced by the heat insulation layer, thus improving the heat insulation performance of the combustion furnace.

[0020] The beneficial effects of this application are:

[0021] 1. This toxic smoke detection and flue gas recovery device, by setting up a wire brush, a moving plate and an electric push rod, uses the extension and retraction of the electric push rod to move the moving plate, which in turn moves the wire brush, and the wire brush cleans the ash on the surface of the plate. This avoids the problem of traditional toxic smoke detection devices requiring manual cleaning of the ash on the surface of the plate after combustion, which leads to a waste of human resources, and improves practicality.

[0022] 2. This toxic smoke detection and recovery device, by setting up a recovery pump, a second delivery pipe and a storage pipe, draws the residual toxic smoke inside the detection box into the second delivery pipe through the recovery pump, and then the second delivery pipe transports the toxic smoke into the storage pipe, where the storage pipe stores the toxic smoke. This avoids the problem of traditional toxic smoke detection devices being unable to recover the toxic smoke after detection, thus improving practicality. Attached Figure Description

[0029] Reference Figures 1-3 A toxic smoke detection and flue gas recovery device includes a base 1, a combustion furnace 6 fixedly connected to the top of the base 1, a detection mechanism 4 on one side of the combustion furnace 6, and an air pump 42 fixedly connected to the combustion furnace 6. A delivery pipe 41 is fixedly connected to one side of the air pump 42, and a detection box 43 is fixedly connected to the side of the delivery pipe 41 away from the air pump 42. The detection box 43 is fixedly connected to the base 1, and a sealing door 44 is hinged to the surface of the detection box 43. By opening the sealing door 44, mice are placed inside the detection box 43, and then the sealing door 44 is closed. Toxic smoke from inside the combustion furnace 6 is then drawn into the delivery pipe 41, and the delivery pipe 41 then delivers the toxic smoke to the detection box 43, exposing the mice to the flue gas environment. Indicators such as respiratory rate and mortality rate are observed, and the toxicity index is calculated. This allows for a better estimation of the toxicity index.

[0030] Reference Figures 1-2 A recycling mechanism 5 is provided on the side of the detection mechanism 4 away from the combustion furnace 6. The recycling mechanism 5 includes a recycling pump 51, which is fixedly connected to the detection box 43. A second conveying pipe 52 is fixedly connected to one side of the recycling pump 51, and a storage pipe 53 is fixedly connected to the side of the second conveying pipe 52 away from the recycling pump 51. The storage pipe 53 is fixedly connected to the base 1. The recycling pump 51 draws the toxic fumes remaining inside the detection box 43 into the second conveying pipe 52, and then the second conveying pipe 52 transports the toxic fumes to the storage pipe 53, where the storage pipe 53 stores the toxic fumes, thus enabling better recycling of the toxic fumes.

[0031] Reference Figure 1 A discharge pipe 11 is fixedly connected to the side of the storage pipe 53 away from the delivery pipe 52. A valve is fixedly connected to the surface of the discharge pipe 11. The valve on the surface of the discharge pipe 11 is used to open and close the discharge pipe 11, and the toxic fumes inside the storage pipe 53 are discharged through the discharge pipe 11, which can better discharge the toxic fumes inside the storage pipe 53.

[0032] Reference Figures 1-2 The combustion furnace 6 is equipped with a protection mechanism 3 inside. A cleaning mechanism 2 is provided on one side of the protection mechanism 3. The cleaning mechanism 2 includes an electric push rod 23, which is fixedly connected to the combustion furnace 6. A movable plate 22 is fixedly connected to the telescopic end of the electric push rod 23. The movable plate 22 is slidably connected to the combustion furnace 6. A wire brush 21 is fixedly connected to the surface of the movable plate 22. A placement plate 9 is slidably connected inside the combustion furnace 6. A collection box 7 is provided at the bottom of the placement plate 9. The collection box 7 is slidably connected to the combustion furnace 6.

[0033] Reference Figure 2 An igniter 8 is fixedly connected inside the combustion furnace 6. By connecting the igniter 8 to the inside of the combustion furnace 6, the material inside the combustion furnace 6 can be ignited by the igniter 8, which can better ignite the material inside the combustion furnace 6.

[0034] Reference Figure 3 A laser particle size analyzer 10 is fixedly connected inside the detection box 43. The laser particle size analyzer 10 is fixedly connected inside the detection box 43, and the particle size distribution of the smoke particles is analyzed by the laser particle size analyzer 10 to assess the breathing penetration risk of ultrafine particles. This allows for a better analysis of the particle size distribution of smoke particles and an assessment of the breathing penetration risk of ultrafine particles.

[0035] Reference Figure 2 The protection mechanism 3 includes a motor 31, which is fixedly connected to the combustion furnace 6. A threaded rod 33 is fixedly connected to the output end of the motor 31. A baffle 32 is threadedly connected to the outer surface of the threaded rod 33. The baffle 32 is slidably connected to the combustion furnace 6. A limit rod 34 is slidably connected inside the baffle 32. The limit rod 34 is fixedly connected to the combustion furnace 6. The rotation of the output end of the motor 31 drives the threaded rod 33 to rotate, which in turn drives the baffle 32 to move. The limit rod 34 then limits the movement of the baffle 32, and the baffle 32 protects the wire brush 21, thus providing better protection for the wire brush 21.

[0036] Reference Figure 4 The combustion furnace 6 is internally fixedly connected with a heat insulation layer 12, which is made of rock wool. The heat insulation performance of the combustion furnace 6 can be better enhanced by the heat insulation layer 12, which is internally fixedly connected with the heat insulation layer 12.

[0037] Working principle: The material to be burned is placed on the surface of the placement plate 9, and then the igniter 8 ignites the material. The output end of the motor 31 rotates, driving the threaded rod 33 to rotate. The rotation of the threaded rod 33 then moves the baffle 32. The limiting rod 34 limits the movement of the baffle 32, which in turn protects the wire brush 21 from damage due to high temperature. The sealing door 44 is then opened, and a mouse is placed inside the detection box 43. The sealing door 44 is then closed, and the toxic fumes inside the combustion furnace 6 are drawn into the conveying pipe 41. The conveying pipe 41 then transports the toxic fumes to the detection box 43, allowing the toxic fumes to dissipate. Mice are exposed to a smoke environment, and indicators such as respiratory rate and mortality rate are observed to calculate the toxicity index. Then, the residual toxic smoke inside the detection box 43 is sucked into the delivery pipe 52 by the recovery pump 51. The delivery pipe 52 then transports the toxic smoke to the storage pipe 53, where it is stored. After the test is completed, the output end of the motor 31 rotates to raise the baffle 32. The telescopic end of the electric push rod 23 then moves the moving plate 22, which in turn moves the wire brush 21. The wire brush 21 cleans the ash on the surface of the placement plate 9, and the collection box 7 collects the ash.
