Description

Technical Field

[0001] The invention relates to the field of detection technology, in particular to a biomass detection device for determining phenolic compounds in water. Background Art

[0002] Phenolic compounds are common water pollutants that may come from industrial wastewater, agricultural runoff or biomass degradation. Biomass (such as plant residues, wood, etc.) may release phenolic compounds during natural degradation or combustion, and cause environmental pollution after entering the water body. Some biomass (such as wood processing waste, crop straw) may release phenolic compounds during stacking or processing. Therefore, it is necessary to detect phenolic compounds in water to evaluate their impact on the environment. The extraction method is an effective method for purifying phenolic compounds. First, select an organic solvent that is immiscible with water. Since the solubility of phenolic compounds is greatly affected by pH value, it is usually necessary to adjust the pH of the water sample to 3-5 to promote the existence of phenolic compounds in molecular form and improve the extraction efficiency. The adsorbent is loaded into the solid phase adjustment interface, and the adjustment interface is rinsed with appropriate organic solvents and deionized water in turn to activate the adsorbent. The pretreated water sample passes through the adjustment interface so that the phenolic compounds are adsorbed by the adsorbent. According to the actual situation, the adjustment interface is rinsed with deionized water multiple times to remove impurities. Finally, the phenolic compounds are eluted with a small amount of organic solvent and the eluent is collected.

[0003] At present, from adjusting the pH value of water samples to filling solid phase extraction columns, to pre-treating water samples, eluting columns, and eluting targets, the entire process requires manual addition of reagents, turning the extraction column discharge knob, and waiting at each step. Frequent operations and repeated steps can easily lead to fatigue of experimental operators, especially when dealing with a large number of samples, which may affect the experimental efficiency and consistency of results, and the detection efficiency is poor; therefore, it does not meet the existing needs. In this regard, we propose a biomass detection device for the determination of phenolic compounds in water. Summary of the invention

The needle head 130 and the groove 131 are intermittently slidably engaged. The movement of the reciprocating plate 141 drives the rectangular plate 128 on the side of the reciprocating plate 141 and the C-shaped connecting rod 129 on the top of the rectangular plate 128 to move, thereby driving the reagent tube 151 engaged in the suspension clamping ring 150 at the end of the C-shaped connecting rod 129 to move. When the needle head 130 at the bottom of the reagent tube 151 moves to the tube mouth of the extraction column 300, the needle head 130 and the groove 131 are slidably engaged, so that it can pass through the tube mouth of the extraction column 300 smoothly, so that the reagent tube 151 can be docked with the extraction column 300, and the reagent can flow into the extraction column 300 for solid phase extraction reaction.

[0035] See Figure 6 A limiting ring 132 is sleeved on the outside of the reagent tube 151, and the limiting ring 132 is engaged on the top of the suspension clamping ring 150. The limiting ring 132 limits the upper and lower heights of the reagent tube 151 placed on the suspension clamping ring 150, thereby preventing the reagent tube 151 from being unable to engage with the suspension clamping ring 150 due to its small diameter.

[0036] A piston chamber 133 is provided inside the reagent tube 151, and the piston chamber 133 is connected to the connecting groove 124. A moving rod 135 is connected inside the reagent tube 151, and a piston block 136 is connected to the end of the moving rod 135. The piston block 136 is slidably engaged with the piston chamber 133, and a disc 137 is connected to the other end of the moving rod 135. When the disc 137 is pressed by an external force, the disc 137 drives the moving rod 135 and the piston block 136 at the other end of the moving rod 135 to squeeze the reagent, and squeeze the reagent into the interior of the extraction column 300 to react with the sample.

[0037] See Figure 9-12 A storage slot 170 is provided inside the fixed box 113, and a first fixed slot 171 and a second fixed slot 172 are provided inside the storage slot 170 respectively, and a connecting cavity 173 is provided between the first fixed slot 171 and the second fixed slot 172, and an extrusion block 174 is slidably installed inside the first fixed slot 171, and a pressing plate 175 is slidably installed inside the second fixed slot 172, and a first inelastic pull rope 180 is connected between the extrusion block 174 and the pressing plate 175, and a first return spring 181 is sleeved on the outer side of the first inelastic pull rope 180, and one end of the first return spring 181 is connected to the inside of the first fixed slot 171, and the first return spring 181 The other end is connected to the side of the extrusion block 174. A second return spring 185 is also sleeved on the outside of the first inelastic pull rope 180. One end of the second return spring 185 is connected to the side of the pressing plate 175. The other end of the second return spring 185 is connected to the inside of the second fixing groove 172. The side of the reagent tube 151 is pressed and matched with the extrusion block 174. The pressing plate 175 is used in conjunction with the disc 137. The first guide wheel 182, the second guide wheel 183 and the third guide wheel 184 are rotatably installed in the inner wall of the connecting cavity 173. The first inelastic pull rope 180 passes through the sides of the first guide wheel 182, the second guide wheel 183 and the third guide wheel 184. The first return spring 181 and the second return spring 185 are jointly configured as compression springs, and the force of the first return spring 181 is greater than the force of the second return spring 185. Therefore, in normal state, the extrusion block 174 protrudes and the pressing block is hidden, and the reciprocating plate 141 drives the suspension clamping ring 150 and the reagent tube 151 inside the suspension clamping ring 150 to move. While moving, the disc 137 and the moving rod 135 are located inside the storage groove 170 and move. The suspension clamping ring 150 and the reagent tube 151 jointly squeeze the extrusion block 174 protruding from the first fixed groove 171, and the extrusion block 174 protrudes from the first fixed groove 171. Under the external force, the first return spring 181 on the side of the extrusion block 174 is compressed, and the first inelastic drawstring 180 on the side of the extrusion block 174 is relaxed. The first inelastic drawstring 180 slides on the sides of the first guide wheel 182, the second guide wheel 183 and the third guide wheel 184, so that the second return spring 185 is reset and released, thereby driving the pressing plate 175 to press the disc 137, and the disc 137 drives the moving rod 135 and the piston block 136 at the other end of the moving rod 135 to squeeze the reagent, and squeeze the reagent into the interior of the extraction column 300, replacing the manual operation; It should be noted that the extrusion block 174 is configured as a wedge-shaped block, and the suspension clamping ring 150 and the reagent tube 151 are in contact with the inclined surface of the extrusion block 174 during the movement.

[0038] The end of the reciprocating plate 141 is integrally connected with the transverse plate 192, and the side of the transverse plate 192 is connected with a threaded head 210. The output shaft of the cylinder 195 passes through the side of the side plate 112. The end of the output shaft of the cylinder 195 is rotatably installed with a connector 193. The inner wall of the connector 193 is provided with a threaded groove 194. The threaded head 210 is threadedly connected with the threaded groove 194. Start the cylinder 195. When the output shaft of the cylinder 195 drives the connector 193 to move, the connector 193 is manually rotated and connected to the end of the threaded head 210. Start the cylinder 195 again, and the cylinder 195 drives the transverse plate 192 and the reciprocating plate 141 on the side of the transverse plate 192 to move.

[0039] See Figure 11-12A force storage groove 220 is also provided inside the fixed box 113, and the force storage groove 220 communicates with the first fixed groove 171 and the second fixed groove 172. A first protrusion 221 is connected to the inner wall of the force storage groove 220, and a fourth guide wheel 212 is rotatably connected inside the force storage groove 220. A force storage assembly 213 is provided inside the force storage groove 220, and the force storage assembly 213 includes a force storage spring 214 and a second inelastic pull rope 215. The force storage spring 214 is connected to the side of the first protrusion 221, and an active block 216 is connected to the end of the force storage spring 214. A pull ring 217 is connected to the side of the pressing plate 175. Two ends of the second inelastic pull rope 215 are respectively connected to the sides of the active block 216 and the pull ring 217. The second inelastic pull rope 215 is sleeved on the side of the fourth guide wheel 212, and a second protrusion 218 is connected to the side of the extrusion block 174. The movable block 216 is slidably matched with the second protrusion 218. The adjustment interface 152 is provided with two groups. The specifications and structures of the two groups of adjustment interfaces 152 are the same. The tooth groove sections 142 are set to be a group of two sections. The two tooth groove sections 142 of each group are located on both sides of the adjacent rectangular plate 128. The initial state of the second inelastic pull rope 215 is set to a relaxed state. When the extrusion block 174 is squeezed, the extrusion block 174 pulls the second inelastic pull rope to rotate on the fourth guide wheel 212. When the extrusion block 174 is completely squeezed into the first fixed groove 171, the second inelastic pull rope 215 is pulled, and at the same time, the storage spring 214 is driven to contract and store force. The movable block 216 at the end of the storage spring 214 retracts and is hidden. The second protrusion 218 is not blocked, and the pressing plate 175 is ejected from the second fixed groove 172 to press the disc 137.

[0040] In this embodiment, the mounting plate 120 is clamped on the pressure extraction box 110 by setting the reciprocating plate 141, the reagent tube 151 is manually placed in the suspension clamping ring 150, and the cylinder 195 is started. The cylinder 195 drives the reciprocating plate 141 to move, and the movement of the reciprocating plate 141 drives the rectangular plate 128 on the side of the reciprocating plate 141 and the C-shaped connecting rod 129 on the top of the rectangular plate 128 to move, thereby driving the reagent tube 151 clamped in the suspension clamping ring 150 at the end of the C-shaped connecting rod 129 to move, and the needle head 130 at the bottom of the reagent tube 151 moves. When the needle head 130 moves to the nozzle of the extraction column 300, the needle head 130 slides and engages with the groove 131, so that it can pass through the nozzle of the extraction column 300 smoothly, so that the reagent tube 151 can dock with the extraction column 300, and the reagent can flow into the extraction column 300 for extraction. The reciprocating plate 141 drives the suspension clamping ring 150 and the reagent tube 151 inside the suspension clamping ring 150 to move. At the same time, the disk 137 and the moving rod 135 move inside the storage groove 170, and the suspension clamping ring 150 and the reagent tube 151 jointly squeeze the first fixed groove 171. The protruding extrusion block 174 is squeezed by an external force, so that the first return spring 181 on the side of the extrusion block 174 is completely contracted, and the first inelastic drawstring 180 on the side of the extrusion block 174 slides on the sides of the first guide wheel 182, the second guide wheel 183 and the third guide wheel 184. At this time, the second return spring 185 is reset to drive the first inelastic drawstring 180, and the second inelastic drawstring 215 is initially set to a relaxed state. When the extrusion block 174 is squeezed, the extrusion block 174 pulls the second inelastic drawstring 215 on the fourth guide wheel 212 When the squeezing block 174 is completely squeezed into the first fixed groove 171, the second inelastic pull rope 215 is pulled, and at the same time, the force storage spring 214 is driven to contract and store force, and the movable block 216 at the end of the force storage spring 214 is retracted and hidden, and the second protrusion 218 is not blocked, and the pressing plate 175 is ejected from the second fixed groove 172, and the squeezing block 174 presses the disc 137, and the disc 137 drives the moving rod 135 and the piston block 136 at the other end of the moving rod 135 to squeeze the reagent, and squeeze the reagent into the interior of the extraction column 300 to react with the sample.

[0041] When the suspension clamping ring 150 and the extrusion block 174 are offset, the extrusion block 174 and the movable clamping block 216 are reset. Since the movable clamping block 216 is configured as a wedge-shaped block with the inclined surface facing downward, the second protrusion 218 can smoothly return to the original position.

[0042] In this solution, the cylinder 195 drives the movement of the reciprocating plate 141 and other components, so that the reagent injection process is automated. This not only improves work efficiency and reduces the labor intensity of manual operation, but also avoids operational errors caused by human factors. It is suitable for large-scale sample extraction and processing, and solves the problem that frequent operations and repeated steps easily lead to fatigue of experimental operators, especially when processing a large number of samples, which may affect the experimental efficiency and consistency of results, and the problem of poor detection efficiency.

[0043] Embodiment 2: This embodiment is intended to promote the solution of the problem that when performing solid phase extraction, the knob of the adjustment interface 152 needs to be adjusted twice each time a reagent is added, which greatly reduces the overall processing efficiency. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-12 A mounting box 111 is installed on the side of the pressure extraction box 110, a side plate 112 is connected to the top of the mounting box 111, a fixed box 113 is arranged on the top of the mounting plate 120, a waste liquid box 121 is placed inside the pressure extraction box 110, by placing the waste liquid box 121 inside the pressure extraction box 110, the waste liquid in the extraction column 300 is extracted and flows into the waste liquid box 121, a piston ring 122 is connected to the bottom of the mounting plate 120, the piston ring 122 is engaged with the inner wall of the pressure extraction box 110, so that the mounting plate 120 and the pressure extraction box 110 jointly create a closed space, and an adjustment interface 152 is arranged on the side of the pressure extraction box 110. By adjusting the adjustment interface 152, the air pressure inside the pressure extraction box 110 can be quickly made to meet the experimental conditions, thereby accelerating the extraction progress. The adjustment interface 152 is usually composed of two parts: an actuator and an adjustment mechanism. The actuator drives the regulating mechanism according to the signals sent by the control system, such as electrical signals and gas signals, to change the flow area of ​​the valve, thereby achieving the adjustment of parameters such as pressure and flow.

[0044] A connecting groove 124 is provided inside the regulating interface 152, and the interior of the extraction column 300 is connected to the connecting groove 124. A rotating ball 125 is connected inside the regulating interface 152, and a flow groove 126 is provided in the middle of the rotating ball 125. When the flow groove 126 overlaps with the notch of the connecting groove 124, the connecting groove 124 and the flow groove 126 are connected to the interior of the pressure extraction box 110. When the gear 140 rotates, the shaft body 127 in the middle of the gear 140 drives the rotating ball 125 to rotate. When the flow groove 126 is misaligned with the notch of the connecting groove 124, the connecting groove 124 and the flow groove 126 are separated from the interior of the pressure extraction box 110, so that the waste liquid extracted by the extraction column 300 cannot flow to the waste liquid tank 121 through the regulating interface 152, so that the added reagent can fully react with the interior of the extraction column 300. A rotating shaft body 127 is connected to the side of the rotating ball 125 . The rotating shaft body 127 passes through the adjustment interface 152 , and the gear 140 is coaxially connected to the rotating shaft body 127 .

[0045] In this embodiment: through the setting of the adjustment interface 152, the adjustment interface 152 cooperates with the reciprocating plate 141, and the reciprocating plate 141 drives the reagent tube 151 to move and dock with the extraction column 300. At the same time, when the gear 140 rotates, the shaft body 127 in the middle of the gear 140 drives the rotating ball 125 to rotate. When the flow groove 126 and the notch of the connecting groove 124 are misaligned, the connecting groove 124, the flow groove 126 and the internal partition of the pressure extraction box 110 prevent the waste liquid extracted by the extraction column 300 from flowing to the waste liquid tank 121 through the adjustment interface 152. At this time, the reagent reacts with the sample. After the reaction is completed, the reagent tube 151 leaves, and the gear 140 engages with the tooth groove on the side of the reciprocating plate 141, driving the rotating ball 125 to rotate, so that the flow groove 126 overlaps with the notch of the connecting groove 124, and the waste liquid flows to the waste liquid tank 121. During manual operation, it is easy to be affected by factors such as fatigue, emotion, and attention, thereby causing operation errors. For example, when closing and opening the adjustment interface 152, manual operation may not ensure that the force and time of each action are completely consistent. However, the system controls the rotating ball 125 through the precise meshing of the gear 140 and the tooth groove, which can ensure that the state of closing and opening the adjustment interface 152 is consistent each time, making the reaction time of the reagent and the timing of waste liquid discharge more accurate.

[0046] Embodiment 3: This embodiment is intended to promote the solution of the problem that the flow rate of the regulating interface 152 needs to be adjusted according to the reaction conditions when performing solid phase extraction detection. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-12 The first piston cylinder 301 and the second piston cylinder 302 are installed on the mounting plate 120, and an air pipe 303 is connected between the first piston cylinder 301 and the second piston cylinder 302. A baffle 304 is slidably engaged inside the reagent tube 151, and the baffle 304 is located at the outlet of the connecting groove 124. The end of the baffle 304 is connected to the first piston disc 305, and the first piston disc 305 is slidably connected to the inside of the first piston cylinder 301. The second piston disc 306 is slidably installed inside the second piston cylinder 302, and the side of the second piston disc 306 is connected to a connecting rod. 307, the connecting rod 307 extends to the outside of the second piston cylinder 302, and the end of the connecting rod 307 is connected to a pressing handle 308; by manually controlling the pressing handle 308, the connecting rod 307 on the side of the pressing handle 308 drives the second piston disc 306 to move, pushing the gas to the air pipe 303, and then squeezing the gas from the air pipe 303 to the inside of the first piston cylinder 301, pushing the first piston disc 305 to move, thereby slowly driving the baffle 304 to block the outlet of the connecting groove 124, thereby slightly reducing the extraction flow rate, and vice versa, speeding up the flow rate.

[0047] In order to perform multiple groups of tests simultaneously, two groups of adjustment interfaces 152 are provided. The specifications and structures of the two groups of adjustment interfaces 152 are the same. The tooth groove segments 142 are provided in groups of two. The two tooth groove segments 142 of each group are located on both sides of the adjacent rectangular plate 128 .

[0048] In the present embodiment: through the arrangement of the first piston cylinder 301 and the second piston cylinder 302, the cooperation of the baffle 304 and the adjustment interface 152, through the manual operation of the pressing handle 308, the connecting rod 307 on the side of the pressing handle 308 drives the second piston disc 306 to move, pushing the gas to the air pipe 303, and then squeezing the gas from the air pipe 303 to the inside of the first piston cylinder 301, pushing the first piston disc 305 to move, thereby slowly driving the baffle 304 to block the outlet of the connecting groove 124, and driving the baffle 304 to move by the transfer of gas between the piston cylinders, which can achieve small-scale and precise adjustment of the extraction flow rate, making the entire solution better.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
