[0028] An industrial waste gas recovery device, such as Figures 1-5 As shown, it includes a fixed box 100. A first connecting pipe 1121 is fixedly connected to the outer wall of one end of the fixed box 100. An air inlet pipe 112 is fixedly connected to the end of the first connecting pipe 1121 away from the fixed box 100. Exhaust gas can be discharged into the fixed box 100 for treatment through the first connecting pipe 1121 and the air inlet pipe 112.

[0029] For example, a first fan 1132 is movably installed on the inner wall of the first connecting pipe 1121, and the exhaust gas can be transported through the first fan 1132;

[0030] For example, a first rotating rod 1131 is fixedly connected to the center of the first fan 1132. A first mounting rod 113, which is fixedly connected to the inner wall of the fixed box 100, is fixedly sleeved on the outer wall of the first rotating rod 1131. A first pulley 114 is fixedly sleeved on the side of the outer wall of the first rotating rod 1131 away from the first mounting rod 113. A second pulley 1141 is provided above the first pulley 114. A first belt 1142 is sleeved on the outer wall of the first pulley 114 and the second pulley 1141. A movable rod 115 is fixedly connected to the end of the first rotating rod 1131 away from the first fan 1132. The movable rod 115 moves up and down. Two connecting rods 1151 are symmetrically fixed to one side of each end. A cleaning roller 1152 is fixedly connected to the end of each connecting rod 1151 away from the movable rod 115. The first belt 114 can be driven to rotate by the second pulley 1141 in conjunction with the first belt 1142. The first belt 114 can drive the first rotating rod 1131 to rotate. The first rotating rod 1131 can drive the first fan 1132 to rotate. At the same time, the movable rod 115 can be driven to rotate by the first rotating rod 1131. The cleaning roller 1152 can be driven to rotate by the movable rod 1151 in conjunction with the connecting rod 1151.

[0031] For example, a filter screen 119 is fixedly installed on the inner wall of the fixed box 100, and a cleaning roller 1152 is attached to the filter screen 119. The filter screen 119 can be cleaned by the cleaning roller 1152 to prevent the filter screen 119 from clogging.

[0032] For example, multiple sets of activated carbon plates 1191 located inside the fixed box 100 are fixedly installed on the side of the filter screen 119 away from the cleaning roller 1152. The activated carbon plates 1191 can be used to filter the exhaust gas entering the fixed box 100.

The second connecting pipe 1122 is fixedly connected to an exhaust pipe 1123 at one end away from the fixed box 100. A second fan 1185 is movably installed on the inner wall of the exhaust pipe 1123. By using the second fan 1185, the filtered gas inside the fixed box 100 can be discharged through the second connecting pipe 1122 and the exhaust pipe 1123.

[0035] In some examples, please refer to Figure 3 , Figure 4 , Figure 5 A second rotating rod 1183 is fixedly connected at the center of the second fan 1185, and the second fan 1185 can be driven to rotate by the second rotating rod 1183.

[0036] For example, the end of the second rotating rod 1183 away from the second fan 1185 is movably connected to a second mounting rod 1184 that is fixedly connected to the inner wall of the fixed box 100. The second fan 1185 can be installed and used through the second mounting rod 1184.

[0037] For example, a fourth pulley 1181 is fixedly sleeved on the outer wall of the second rotating rod 1183 between the second fan 1185 and the second mounting rod 1184. A third pulley 118 is provided above the fourth pulley 1181. A second belt 1182 is sleeved on the outer wall of the third pulley 118 and the fourth pulley 1181. The third pulley 118 and the second belt 1182 can drive the fourth pulley 1181 to rotate, thereby driving the second rotating rod 1183 to rotate, which facilitates the rotation of the second fan 1185.

[0038] In some examples, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A transmission rod 117 is fixedly sleeved at the center of the third pulley 118 and the second pulley 1141. A fixed cover 1172 is fixedly connected to the top of the fixed box 100. The transmission rod 117 is movably connected to the inner wall of the fixed cover 1172. The transmission rod 117 can be installed and used through the fixed cover 1172.

[0039] For example, one end of the transmission rod 117 is connected to a motor 1171 via a coupling. The motor 1171 is fixedly installed on the inner wall of one end of the transmission rod 117. The motor 1171 can drive the transmission rod 117 to rotate, and the transmission rod 117 can drive the second pulley 1141 and the third pulley 118 to rotate.

[0040] For example, the top of the fixed box 100 is symmetrically provided with two sets of slots that match the first belt 1142 and the second belt 1182. The slots facilitate the use of the first belt 1142 and the second belt 1182.

[0041] In some examples, please refer to Figure 1 and Figure 2 The bottom of the fixed box 100 is provided with a through groove, and a fixed frame 1001 located below the through groove is fixedly connected to the bottom of the fixed box 100. A collection box 1002 is movably connected to the inner wall of the fixed frame 1001, and a handle 1003 is fixedly connected to the surface of the collection box 1002. The through groove facilitates the collection of dust swept off the filter screen 119 through the collection box 1002. The handle 1003 facilitates the pulling of the collection box 1002 out of the fixed frame 1001, thereby facilitating the cleaning of the dust inside the collection box 1002.

[0042] For example, support plates 111 are fixedly connected to both sides of the bottom end of the fixed box 100, and support rods 1111 are symmetrically fixedly connected to the bottom ends of the two sets of support plates 111. The fixed box 100 can be supported by the support plates 111 and the support rods 1111.

[0043] In some examples, please refer to Figure 1 Two sets of cabinet doors 110 are symmetrically and movably connected to one side surface of the fixed box 100. Each set of cabinet doors 110 is fixedly connected to a handle 1101. The cabinet doors 110 facilitate the maintenance and use of the equipment inside the fixed box 100.

[0044] The working principle of this utility model is as follows: In use, exhaust gas is discharged into the fixed box 100 through the air inlet pipe 112 and the first connecting pipe 1121. The motor 1171 is started, and the motor 1171 drives the transmission rod 117 to rotate. The transmission rod 117 drives the second pulley 1141 to rotate. The second pulley 1141, together with the first belt 1142, drives the first pulley 114 to rotate. The first pulley 114, together with the first rotating rod 1131, drives the first fan 1132 to rotate, thereby facilitating the transportation of exhaust gas through the first fan 1132. The exhaust gas is filtered through the filter screen 119 and the activated carbon plate 1191.

[0045] Furthermore, the transmission rod 117 drives the third pulley 118 to rotate, and the third pulley 118, in conjunction with the second belt 1182, drives the fourth pulley 1181 to rotate. This facilitates the use of the fourth pulley 1181 to drive the second rotating rod 1183 to rotate. The second rotating rod 1183, in conjunction with the second fan 1185, discharges the filtered gas through the second connecting pipe 1122 and the exhaust pipe 1123, which is convenient for subsequent recycling.

[0046] Furthermore, when the filter screen 119 needs to be cleaned, the first rotating rod 1131 drives the movable rod 115 to rotate. The movable rod 115, through the connecting rod 1151, drives the cleaning roller 1152 to rotate, thereby facilitating the sweeping of particles off the filter screen 119 by the cleaning roller 1152, preventing the filter screen 119 from becoming clogged, and thus facilitating the cleaning and use of the filter screen 119. The swept-off dust falls into the collection box 1002 through the channel, and the collection box 1002 collects the dust, thus facilitating subsequent cleaning.
