DETAILED DESCRIPTION

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] like Figure 1-Figure 4 As shown, the utility model proposes an easy-to-install calcining furnace volatilization excess flue collection device, comprising a wrapping part 1, a control panel 2, a cover plate 3, a shock absorbing part 4, a connecting pipe 5, a shell 6, a connecting rod 7, a branch pipe 9, a water tank 10, a collecting bucket 11, a connecting pipe 12, a heating box 13, an oxidation plate 14, a cover body 15, a heating element 16, an electrode sheet 17 and a control module 18;

[0025] A connecting piece 8 is provided inside the shell 6; the connecting piece 8 is connected to the connecting pipe 5; the end of the connecting piece 8 away from the connecting pipe 5 is connected to multiple groups of branch pipes 9; the end of the multiple groups of branch pipes 9 away from the connecting piece 8 is connected to the bottom of the water tank 10; the bottom of the water tank 10 is connected to the bottom of the inner wall of the shell 6; the top of the water tank 10 is connected to the collecting bucket 11; the top of the collecting bucket 11 is connected to the connecting pipe 12; the end of the connecting pipe 12 away from the collecting bucket 11 is connected to the heating box 13; the bottom of the inner wall of the shell 6 is connected to the heating box 13; multiple groups of mounting grooves are provided inside the heating box 13, and the mounting grooves are connected to the oxidation plate 14; a through hole is provided on the end of the heating box 13 away from the connecting pipe 12; the top of the heating box 13 is connected to the cover body 15; the bottom of the cover body 15 is connected to multiple groups of heating elements 16; the bottom of the cover body 15 is connected to multiple groups of electrode sheets 17; the side of the electrode sheet 17 is in contact with the side of the oxidation plate 14; the top of the cover body 15 is connected to the control module 18; the control module 18 is electrically connected to the electrode sheet 17.

[0026] The wrapping portion 1 includes a foot 101, a docking piece 102, a docking tube 103 and a connecting shell 104. The two sides of the connecting shell 104 are symmetrically connected to multiple groups of docking pieces 102. One end of the multiple groups of docking pieces 102 away from the connecting shell 104 is connected to the docking tube 103. The bottom of the connecting shell 104 is connected to multiple groups of foots 101.

[0027] The shock absorbing part 4 includes a shock absorbing damping rod plate 401 and a shock absorbing damping rod 402. The bottom of the shock absorbing damping rod plate 401 is connected to the bottom of the inner wall of the connecting shell 104. The top of the shock absorbing damping rod plate 401 is connected to multiple groups of shock absorbing damping rods 402. The tops of the multiple groups of shock absorbing damping rods 402 are in contact with the bottom of the shell 6.

[0028] The control module 18 is provided with a battery pack and a current sensor. The current sensor is electrically connected to the electrode sheet 17 . The battery pack is connected to the plurality of heating elements 16 . The current sensor is control-connected to the control panel 2 .

[0029] A sealing member is provided on the inner wall of the installation groove in the heating box 13 , and the sealing member is in contact and pressed against the side surface of the oxidation plate 14 , and an airtight layer is provided on the sealing member.

[0030] The butt joint pipe 103 is provided with a connecting ring, a sealing member is provided on the connecting ring, and a plurality of connecting holes are provided on the connecting ring. The plurality of connecting holes are arranged in a circle on the side of the connecting ring. The structure of the connecting pipe 5 is the same as that of the butt joint pipe 103 .

[0031] The width of the cover plate 3 is greater than the width of the through hole at the top of the connecting shell 104 . A sealing ring is provided on the bottom of the cover body 15 , and the sealing ring contacts and is squeezed with the top of the heating box 13 .

[0032] In this embodiment, the device can adsorb and recover toxic and harmful gases generated after calcining carbon raw materials, thereby preventing toxic gases from entering the air environment. Compared with traditional devices, the structure of the docking piece 102 and the docking tube 103 can reduce the difficulty of the combined docking of the device, and the structure of multiple groups of oxidation plates 14 can effectively reduce the discharge of toxic gases.

[0033] When the device is in working state, the exhaust gas treatment, recovery and collection effect of the device is achieved by combining and connecting the air inlet end on the left side of the device with the exhaust gas end of the calcining furnace.

[0034] When the device is combined and connected with the calcining furnace, the combination of the shell 6 and the cover 3 can place the internal collection and recovery structure of the device inside the connecting shell 104, so that the device can be easily replaced through the structure of the cover 3, which reduces the maintenance difficulty of the device and facilitates the maintenance and replacement of the device. When the shell 6 is set inside the connecting shell 104, it is combined and connected through the connecting pipe 5 to avoid gas leakage inside the connecting shell 104. At this time, the shock-absorbing damping rod 402 of the shock-absorbing part 4 can provide a certain degree of support for the shell 6, which reduces the pulling force of the connecting rod 7 and can facilitate the connection pipe 5 on the side of the shell 5 and the connection pipe 5 on the inner wall of the connecting shell 104 to connect with each other.

[0035] When the multiple groups of connecting pipes 5 inside the connecting shell 104 are connected to each other and stably, the cover 15 is covered on the top of the heating box 13 and the pneumatic heating element 16 is pneumatically heated; the heating elements 16 are staggered in the heating box 13, so that an oxidation plate 14 is provided on the side of each heating element 16, ensuring the stable increase of the temperature of the oxidation plate 14. When the oxidation plate 14 reaches a certain temperature, the control valve is opened to allow the exhaust gas to enter the interior of the device.

[0036] After the calcination tail gas enters the interior of the device through the docking tube 103, the tail gas can enter the connecting piece 8 through the combination of the docking tube 103 and the connecting pipe 5. The multiple groups of branch pipes 9 at the bottom of the connecting piece 8 can disperse the tail gas, so that the tail gas can form more small bubbles instead of a small number of large bubbles after entering the water tank 10. When the tail gas comes into contact with the moisture inside the water tank 10, the moisture can absorb solid impurities such as dust particles carried in the tail gas, thereby making the tail gas purer. However, the solubility of water in carbon monoxide is low. Therefore, the tail gas containing carbon monoxide will pass through the collecting bucket 11 and enter the connecting pipe 12.

[0037] When the exhaust gas containing carbon monoxide enters the heating box 13 through the connecting pipe 12, the carbon monoxide can be fully contacted with the oxidation plate 14 through multiple groups of vertically arranged oxidation plates 14 during the process of carbon monoxide passing through. Due to the heating effect of the heating element 16, the oxidation plate 14 is in a high temperature state. Since the oxidizing property of ferrous oxide on the oxidation plate 14 is greater than that of carbon monoxide, under high temperature catalysis, ferrous oxide will be reduced to iron element, and carbon monoxide will form carbon dioxide and be discharged. Carbon dioxide is non-toxic and odorless and will not pollute the environment. The formed iron element adheres to the surface of the oxidation plate 14. As the iron element increases, the conductivity of the surface of the oxidation plate 14 will gradually increase. When the two ends of the electrode sheet 17 form a passage through the oxidation plate 14, it means that the oxidation plate 14 has been consumed to the threshold value. At this time, a signal is sent through the control module 18 on the top to remind the staff to replace it in time.

[0038] Embodiment 2

[0039] like Figure 1-Figure 4 As shown, the utility model proposes an easy-to-install calcining furnace volatile excess flue collection device. Compared with the first embodiment, the present embodiment further includes a connecting pipe 5, a shell 6, and a connecting rod 7; the side of the wrapping portion 1 is connected to the control panel 2, and a through hole is provided on the top of the wrapping portion 1.

[0040] The structure of the control panel 2 can effectively improve the operating efficiency of the device, reduce the difficulty of use for the staff of the device, and facilitate the staff to confirm the current internal working status of the device, avoiding direct contact between the staff and toxic gases, thereby reducing the risk of use for the staff.

[0041] Embodiment 3

[0043] The combination of the slope and the limiting groove provided on the guide limit member 19 can limit and fix the position of the cover plate 3 when the cover plate 3 is installed and placed on the top of the connecting shell 104, thereby reducing the difficulty of docking the connecting pipe 5. The shell 6 vibrates during the passage of airflow, and the vibration of the shell 6 can be damped by the shock-absorbing damping rod 402 structure at the bottom, thereby avoiding breakage at the docking point of the connecting pipe 5.
