Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a monitoring probe for the concentration of organic waste gas adsorbed and desorbed by activated carbon. Background Art

[0002] The organic waste gas in the paint spraying industry needs to be purified by activated carbon before being discharged, and before being discharged, it will be detected by a monitoring probe. The gas sensor in the detection probe will detect the concentration of harmful molecules in the waste gas. When the concentration of harmful molecules is detected to be too high, it is judged that the activated carbon adsorption is saturated, and an alarm is issued to notify maintenance personnel to replace the activated carbon in time.

[0003] However, the detection probe has the following disadvantages during use: it can only play a monitoring and alarm role, and the activated carbon needs to be replaced manually by maintenance personnel later, which is rather troublesome, and the automation level is low. Therefore, there is room for improvement. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] Some embodiments of the utility model are described below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] Combination Figure 1-5 As shown, this embodiment provides a monitoring probe for the concentration of organic waste gas adsorbed and desorbed by activated carbon, including: a main body module 100.

[0026] Among them, the main module 100 includes a tube body 110, a gas sensor 120 installed on the tube body 110 and extending into the tube body 110, a bracket 130 symmetrically fixed on the inner wall of the tube body 110, a rotating member 140 rotatably installed on the relative bracket 130, a driving member 150 installed on the tube body 110 and extending into the tube body 110 and engaging with the rotating member 140, a cylinder 160 fixedly sleeved on the rotating member 140, a storage box 170 installed at the top end of the tube body 110 and connected to the inner cavity of the tube body 110, a cover plate 180 embedded in the top end of the storage box 170, and an exhaust pipe 190 installed at the bottom end of the tube body 110 and connected to the inner cavity of the tube body 110.

[0027] The end of the tube body 110 is connected to the exhaust gas pipe to facilitate the exhaust gas to enter the inner cavity of the tube body 110 for purification and filtration. The gas sensor 120 is used to detect the concentration of harmful molecules in the exhaust gas after purification and filtration, and determine whether the activated carbon is in a saturated state based on the detection results.

[0028] The bracket 130 is used to install the rotating member 140 and maintain the stability of the rotating member 140. The bracket 130 includes support rods 131 fixed on the inner wall of the tube body 110 in an annular array and bearings 132 installed on the ends of the support rods 131. The rotating member 140 includes a rotating shaft 141 with both ends rotatably installed on the relative bracket 130 and a first bevel gear 142 fixed on the end of the rotating shaft 141. The two ends of the rotating shaft 141 are fixed to the inner ring of the bearing 132 to ensure the stability of the rotating shaft 141 when rotating. The rotating shaft 141 is used to install the cylinder 160 and drive the cylinder 160 to rotate.

[0029] The driving member 150 is used to drive the rotating shaft 141 to rotate, and includes a motor 151 installed on the outer surface of the tube body 110 and the shaft extending into the inner cavity of the tube body 110, and a second bevel gear 152 fixed on the shaft of the motor 151. The second bevel gear 152 is meshed with the first bevel gear 142, so that when the motor 151 is started, it can drive the second bevel gear 152 to rotate, and the rotation of the second bevel gear 152 drives the first bevel gear 142 to rotate. The rotation of the first bevel gear 142 drives the rotating shaft 141 to rotate, and the rotation of the rotating shaft 141 drives the cylinder 160 to rotate.

[0030] The cylinder 160 is arranged in the inner cavity of the tube body 110, and the outer diameter of the cylinder 160 is equal to the inner diameter of the tube body 110, and is used to fill activated carbon particles. An opening 161 is provided on one side of the cylinder 160 to facilitate the replenishment of activated carbon into the cylinder 160 or the removal of activated carbon in the cylinder 160. Through holes 162 are opened in a circular array on both sides of the cylinder 160 to facilitate the exhaust gas to enter the inner cavity of the cylinder 160 for adsorption and filtration by the activated carbon.

[0031] The storage box 170 is arranged at the top of the tube body 110 and is used to store spare activated carbon. When the opening 161 of the cylinder 160 is facing the storage box 170, the activated carbon in the storage box 170 will enter the cylinder 160 along the opening 161 to complete the loading of the activated carbon. The cover plate 180 is used to close the storage box 170. A pull plate is fixed at the top of the cover plate 180 to facilitate the user to move the cover plate 180.

[0032] The discharge pipe 190 is arranged at the bottom end of the tube body 110, and the other end is connected to the burner. When the opening 161 of the cylinder 160 is facing the discharge pipe 190, the activated carbon in the cylinder 160 can be sent into the burner along the discharge pipe 190 to complete the discharge of the saturated activated carbon in the cylinder 160.

[0033] The working principle and use process of the utility model are as follows: when in use, the exhaust gas enters through one side of the tube body 110. When the exhaust gas passes through the cylinder body 160, the activated carbon in the cylinder body 160 adsorbs the harmful molecules in the exhaust gas, and the adsorbed exhaust gas is sent out through the other side of the tube body 110. At the same time, the gas sensor 120 monitors the concentration of harmful molecules in the filtered exhaust gas in real time. When the concentration of harmful molecules is too high, it is judged that the activated carbon is in a saturated state. At this time, the motor 151 is started, and the motor 151 starts to drive the second bevel gear 152 to rotate. The rotation of the second bevel gear 152 drives the first bevel gear 142 to rotate. The rotation of the first bevel gear 142 drives the rotating shaft 141 to rotate. The rotation of the rotating shaft 141 drives the cylinder body 160 to rotate, so that the opening 161 on the cylinder body 160 is aligned with the cylinder body 160. The discharge pipe 190 is aligned, and the saturated activated carbon in the cylinder 160 is sent out through the discharge pipe 190. Then the cylinder 160 continues to rotate so that the opening 161 on the cylinder 160 is aligned with the storage box 170. At this time, the spare activated carbon in the storage box 170 is refilled into the cylinder 160 through the opening 161 to complete the replacement of the activated carbon in the cylinder 160. Then the cylinder 160 continues to rotate so that the opening 161 faces the inner wall of the tube body 110. Although the embodiments of the utility model have been shown and described, ordinary technicians in this field can understand that various changes, modifications, substitutions and modifications can be made to these embodiments without departing from the principles and purpose of the utility model. The scope of the utility model is defined by the claims and their equivalents.
