Description

Technical Field

[0001] This utility model belongs to the field of exhaust gas absorption technology, and in particular relates to a muffle furnace with an activated carbon combustion exhaust gas absorption device. Background Technology

[0002] A muffle furnace is a general-purpose heating device that can be classified into box furnaces, tube furnaces, crucible furnaces, etc., according to its appearance. It has a wide range of applications, including as a sample processing device in fields such as water quality analysis and environmental analysis.

[0003] When processing materials, muffle furnaces generate exhaust gas. Generally, the exhaust gas is treated into harmless gas through multiple steps before being discharged. The exhaust gas first passes through a filter screen, which removes particles such as soot from the exhaust gas. However, after prolonged filtration, the filter screen inevitably accumulates a large amount of impurities, reducing the filtration effect. It usually requires manual cleaning, which is quite troublesome, consuming a lot of labor and time costs, and is also inefficient. Therefore, we propose a muffle furnace with an activated carbon combustion exhaust gas absorption device. Utility Model Content

[0004] The purpose of this invention is to provide a muffle furnace with an activated carbon combustion exhaust gas absorption device. By setting up a cleaning component, specifically, a second motor drives an eccentric turntable to rotate, which in turn drives a reciprocating frame to move. The reciprocating frame drives a moving ring to reciprocate vertically, which in turn drives a filter plate to reciprocate vertically. This vibration shakes most of the impurities on the filter plate into a sliding groove, and the valve is opened to allow the impurities to slide out. The operation is simple, saving significant labor and time costs, and improving cleaning efficiency. It solves the problem that existing exhaust gas first passes through a filter screen, which removes soot and other particles, but after prolonged filtration, the filter screen inevitably accumulates a large amount of impurities, reducing the filtration effect. Manual cleaning is usually required, which is cumbersome, consumes considerable labor and time costs, and is inefficient.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a muffle furnace with an activated carbon combustion exhaust gas absorption device, including a muffle furnace, an exhaust gas collection box fixedly connected to the right side of the muffle furnace, and a sealing strip fixedly connected to the top of the exhaust gas collection box.

[0007] The exhaust gas collection box is equipped with a cleaning assembly, which includes a filter plate. The front and back of the filter plate are slidably connected to the inner wall of the exhaust gas collection box. Two movable rings are fixedly connected to the right side of the filter plate, and two sliding rods are provided on the right side of the filter plate. The outer surface of the sliding rods is slidably connected to the inner wall of the movable rings. A reciprocating frame is fixedly connected to the right side of the movable rings located at the rear. A reciprocating frame is rotatably connected to the back of the reciprocating frame. A motor is fixedly connected to the back of the exhaust gas collection box. A valve is provided on the left side of the motor. The front of the valve is fixedly connected to the back of the exhaust gas collection box. The output end of the front of the motor is fixedly connected to the back of the eccentric turntable. The top and bottom of the slide rod are fixedly connected to the inner wall of the exhaust gas collection box. A guide platform is provided on the left side of the filter plate, and the left side of the guide platform is fixedly connected to the right side of the muffle furnace. A sliding groove is opened on the inner side of the bottom of the exhaust gas collection box. An activated carbon plate is provided on the right side of the filter plate. The front and back of the activated carbon plate are slidably connected to the inner wall of the exhaust gas collection box. A handle is fixedly connected to the top of the activated carbon plate. The moving ring drives the filter plate to reciprocate in the vertical direction, generating vibration that shakes most of the impurities on the filter plate into the sliding groove. Opening the valve allows the impurities to slide out. The operation is simple, which not only saves a lot of labor and time costs, but also improves cleaning efficiency.

[0008] Furthermore, a collection shell is fixedly connected to the right side of the handle, and a purification module is provided on the right side of the collection shell. The bottom of the purification module is fixedly connected to the inner bottom of the exhaust gas collection box. A combustion rack is fixedly connected inside the muffle furnace, and a waste collection box is slidably connected to the bottom of the combustion rack. A pull rod is fixedly connected to the front of the waste collection box. A switch assembly is provided on the right side of the muffle furnace. The switch assembly includes four fixed seats. The left side of the fixed seats is fixedly connected to the right side of the muffle furnace. A motor is fixedly connected to the right side of the muffle furnace. A bidirectional threaded rod is fixedly connected to the front output end of the motor via a coupling. The ash produced after the material is burned will naturally fall into the waste collection box, which not only facilitates the centralized collection of ash but also greatly simplifies the subsequent cleaning work.

[0009] Furthermore, the two upper fixed seats are rotatably connected to the front and back of the bidirectional threaded rod on opposite sides, while the two lower fixed seats are fixedly connected to a slide rod on opposite sides. Two moving rods are slidably connected to the outer surface of the slide rod. The inner top walls of the two moving rods are threadedly connected to the inside of the bidirectional threaded rod. A fixed block is fixedly connected to the outer center of the moving rod. An opening and closing plate is fixedly connected to the left side of the fixed block. The outer surface of the opening and closing plate is slidably connected to the inner wall of the muffle furnace. The two moving rods will move smoothly in opposite directions along the preset path of the slide rod, further driving the movement of the fixed block. The fixed block is connected to the opening and closing plate, so the opening and closing plate will also move accordingly, allowing for free opening and closing and facilitating temperature control of the muffle furnace.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-7 As shown, this utility model is a muffle furnace with an activated carbon combustion exhaust gas absorption device, including a muffle furnace 1, an exhaust gas collection box 2 fixedly connected to the right side of the muffle furnace 1, and a sealing strip 3 fixedly connected to the top of the exhaust gas collection box 2.

[0026] The exhaust gas collection box 2 is equipped with a cleaning component 12, which includes a filter plate 121. The front and back of the filter plate 121 are slidably connected to the inner wall of the exhaust gas collection box 2. Two moving rings 211 are fixedly connected to the right side of the filter plate 121. Two sliding rods 122 are provided on the right side of the filter plate 121. The outer surface of the sliding rods 122 is slidably connected to the inner wall of the moving rings 211. A reciprocating frame 125 is fixedly connected to the right side of the rear moving rings 211. A reciprocating frame 125 is rotatably connected to the back of the reciprocating frame 125. A motor 127 is fixedly connected to the back of the exhaust gas collection box 2. A valve 62 is provided on the left side of the motor 127. The front of the valve 62 is fixedly connected to the back of the exhaust gas collection box 2. The front output end of the motor 127 is fixedly connected to the back of the eccentric turntable 126. The top and bottom of the sliding rods 122 are fixedly connected to the inner wall of the exhaust gas collection box 2. A valve 62 is provided on the left side of the filter plate 121. The system includes a flow guide platform 6, whose left side is fixedly connected to the right side of the muffle furnace 1. A chute 61 is provided on the inner bottom of the exhaust gas collection box 2. An activated carbon plate 123 is located to the right of the filter plate 121. The front and back of the activated carbon plate 123 are slidably connected to the inner wall of the exhaust gas collection box 2. A handle 231 is fixedly connected to the top of the activated carbon plate 123. This invention utilizes a cleaning component 12, specifically a starting motor 127 that drives an eccentric turntable 126 to rotate. The eccentric turntable 126 drives a reciprocating frame 125 to move, which in turn drives a moving ring 211 to reciprocate vertically. The moving ring 211 then drives the filter plate 121 to reciprocate vertically, generating vibration that shakes most of the impurities on the filter plate 121 into the chute 61. Opening the valve 62 allows the impurities to slide out. The system is simple to operate, saving significant labor and time costs while improving cleaning efficiency.

[0027] A collection shell 124 is fixedly connected to the right side of the handle 231. A purification module 7 is provided on the right side of the collection shell 124. The bottom of the purification module 7 is fixedly connected to the inner bottom of the exhaust gas collection box 2.

[0028] A combustion rack 4 is fixedly connected inside the muffle furnace 1. A waste collection box 5 is slidably connected to the bottom of the combustion rack 4. A pull rod 51 is fixedly connected to the front of the waste collection box 5. A switch assembly 11 is set on the right side of the muffle furnace 1. The switch assembly 11 includes four fixed seats 113. The left side of the fixed seats 113 is fixedly connected to the right side of the muffle furnace 1. A motor 111 is fixedly connected to the right side of the muffle furnace 1. A bidirectional threaded rod 112 is fixedly connected to the front output end of the motor 111 through a coupling. In this utility model, by setting the switch assembly 11, the motor 111 is started to drive the bidirectional threaded rod 112 to start rotating. As the bidirectional threaded rod 112 rotates, the two moving rods 115 will move smoothly in opposite directions along the preset path of the slide rod 114, which further drives the movement of the fixed block 116. The fixed block 116 is connected to the opening and closing plate 161, so the opening and closing plate 161 will also move accordingly, allowing for free switching and convenient temperature control of the muffle furnace.

[0029] The two upper fixed seats 113 are rotatably connected to the front and back of the bidirectional threaded rod 112 on opposite sides, and the two lower fixed seats 113 are fixedly connected to the slide rod 114 on opposite sides.

[0030] Two movable rods 115 are slidably connected to the outer surface of the slide rod 114. The inner top wall of the two movable rods 115 is threadedly connected to the inner thread of the bidirectional threaded rod 112. A fixing block 116 is fixedly connected to the outer center of the movable rod 115. An opening and closing plate 161 is fixedly connected to the left side of the fixing block 116. The outer surface of the opening and closing plate 161 is slidably connected to the inner wall of the muffle furnace 1.

[0031] A specific application of this embodiment is as follows: After placing the material on the combustion rack 4, the muffle furnace 1 is started to efficiently burn the material. During this process, the ash produced after the material is burned will naturally fall into the waste collection box 5, which not only facilitates the centralized collection of ash but also greatly simplifies the subsequent cleaning work. In order to effectively control the emission of exhaust gas, the motor 111 is started to drive the bidirectional threaded rod 112 to start rotating. As the bidirectional threaded rod 112 rotates, the two moving rods 115 will move smoothly in opposite directions along the preset path of the slide rod 114, which further drives the movement of the fixed block 116. The fixed block 116 is connected to the opening and closing plate 161, so the opening and closing plate 161 will also move accordingly, ensuring that the exhaust gas can be effectively introduced into the exhaust gas collection box 2. After entering the exhaust gas collection box, the exhaust gas will first be pre-treated by the filter plate 121. This step can filter out a large amount of soot and other impurities in the exhaust gas. Then, the exhaust gas will continue to flow through the activated carbon. The activated carbon plate 123 effectively adsorbs a large amount of harmful gases in the exhaust gas. After these two treatment processes, the exhaust gas has been significantly purified. Subsequently, the exhaust gas is transferred to the purification module 7 through the collection shell 124 for further purification treatment to ensure that the final exhaust gas meets environmental protection standards. Considering that a certain amount of impurities may accumulate on the filter plate 121 after long-term operation, the starting motor 127 will drive the eccentric turntable 126 to start rotating. The rotation of the eccentric turntable 126 will be further converted into the reciprocating motion of the reciprocating frame 125. The reciprocating frame 125 is connected to the moving ring 211, so the moving ring 211 will also reciprocate in the vertical direction. This motion process drives the filter plate 121 to reciprocate in the vertical direction, thereby effectively shaking most of the impurities on the filter plate 121 into the lower slide groove 61. Finally, simply open the valve 62, and these impurities can be easily slid out for centralized treatment.
