Description

Technical Field

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

[0002] Phenolic compounds are common water pollutants, potentially originating from industrial wastewater, agricultural runoff, or biomass degradation. Biomass (such as plant residues and wood) may release phenolic compounds during natural degradation or combustion, potentially polluting water bodies. Certain biomasses (such as wood processing waste and crop straw) may release phenolic compounds during storage or handling, necessitating the detection of phenolic compounds in water to assess their environmental impact. Extraction is an effective method for purifying phenolic compounds. First, a water-immiscible organic solvent is selected. Because the solubility of phenolic compounds is significantly affected by pH, the pH of the water sample is typically adjusted to 3-5 to promote the molecular form of the phenolic compounds and improve extraction efficiency. An adsorbent is loaded into a solid-phase conditioning interface. The conditioning interface is sequentially rinsed with an appropriate organic solvent and deionized water to activate the adsorbent. The pretreated water sample is passed through the conditioning interface to allow the phenolic compounds to be adsorbed by the adsorbent. The conditioning interface is rinsed with deionized water multiple times, as appropriate, to remove impurities. Finally, the phenolic compounds are eluted with a small amount of organic solvent, and the eluate is collected.

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

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1: This example is intended to solve the problem that during the test, the reagent needs to be added manually multiple times and the knob of the adjustment interface 152 needs to be rotated multiple times. The operation is too complicated and may affect the efficiency of the test and the consistency of the results. Figure 1-12A biomass detection device for measuring phenolic compounds in water includes a pressure extraction box 110 and a cylinder 195. The pressure extraction box 110 is provided with a mounting plate 120 at the end thereof for sealing the pressure extraction box 110. The mounting plate 120 is provided with an adjustment interface 152. A gear 140 is installed on the side of the adjustment interface 152. An extraction column 300 is plugged into the adjustment interface 152. A reciprocating plate 141 connected to the cylinder 195 is also provided at the end of the mounting plate 120. A plurality of suspension clamping rings 150 are provided above the reciprocating plate 141. A plurality of tooth groove sections 142 are equidistantly provided on the surface of the reciprocating plate 141. The tooth groove sections 142 are arranged corresponding to the suspension clamping ring 150 and intermittently mesh with the gear 140. A reagent tube 151 for dripping a reagent into the extraction column 300 is detachably provided inside the suspension clamping ring 150.

[0035] An installation box 111 is installed on the side of the pressure extraction box 110 , a side plate 112 is connected to the top of the installation box 111 , and a fixing box 113 is provided on the top of the installation plate 120 .

[0036] See Figure 1-3 The side of the reciprocating plate 141 is connected to a rectangular plate 128, and a C-shaped connecting rod 129 is connected between the rectangular plate 128 and the suspension clamping ring 150. The bottom of the reagent tube 151 is connected to a needle head 130, and the tube mouth of the extraction column 300 is symmetrically provided with grooves 131. The needle head 130 intermittently slides and engages with the groove 131. 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 slides and engages with the groove 131, 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 interior of the extraction column 300 for solid phase extraction reaction.

[0037] See Figure 6 A limiting ring 132 is provided on the outside of the reagent tube 151, and the limiting ring 132 is engaged above 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 the reagent tube 151 having a diameter that is too small.

[0038] 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 to the inside of the reagent tube 151, and a piston block 136 is connected to the end of the moving rod 135. The piston block 136 slides and engages with the piston chamber 133. The other end of the moving rod 135 is connected to a disc 137. 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.

[0039] 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 respectively provided inside the storage slot 170. A connecting cavity 173 is provided between the first fixed slot 171 and the second fixed slot 172. 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. A first non-elastic pull rope 180 is connected between the extrusion block 174 and the pressing plate 175. A first return spring 181 is provided on the outside of the first non-elastic pull rope 180. One end of the first return spring 181 is connected to the inside of the first fixed slot 171. 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 squeezed 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 on 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.

[0040] The first return spring 181 and the second return spring 185 are configured as compression springs. 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. 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 disc 137 and the moving rod 135 move inside the storage groove 170. The suspension clamping ring 150 and the reagent tube 151 jointly squeeze the extrusion block 174 protruding from the first fixed groove 171. The extrusion block 174 Under external pressure, the first return spring 181 on the side of the extrusion block 174 is compressed. At this time, the first inelastic pull rope 180 on the side of the extrusion block 174 is relaxed. The first inelastic pull rope 180 slides on the sides of the first guide wheel 182, the second guide wheel 183, and the third guide wheel 184, causing the second return spring 185 to be reset and released, thereby driving the pressing plate 175 to press the disc 137. 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 into the interior of the extraction column 300, replacing manual operation.

[0041] 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 come into contact with the inclined surface of the extrusion block 174 during the movement.

[0042] The end of the reciprocating plate 141 is integrally connected to the transverse plate 192, and the side of the transverse plate 192 is connected to the 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 connecting head 193. The inner wall of the connecting head 193 is provided with a threaded groove 194. The threaded head 210 is threadedly connected to the threaded groove 194. Start the cylinder 195. When the output shaft of the cylinder 195 drives the connecting head 193 to move, manually rotate the connecting head 193 and connect it to the end of the threaded head 210. Start the cylinder 195 again. The cylinder 195 drives the transverse plate 192 and the reciprocating plate 141 on the side of the transverse plate 192 to move.

[0043] See Figure 11-12, a 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, and the inner wall of the force storage groove 220 is connected with a first protrusion 221, and the fourth guide wheel 212 is rotatably connected inside the force storage groove 220, and 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, and the force storage spring 214 is connected to the side of the first protrusion 221, and the end of the force storage spring 214 is connected to a movable block 216, and a pull ring 217 is connected to the side of the pressing plate 175. The two ends of the second inelastic pull rope 215 are respectively connected to the sides of the movable block 216 and the pull ring 217, and the second inelastic pull rope 215 is sleeved on the side of the fourth guide wheel 212, and the side of the extrusion block 174 is connected to the second protrusion 218. The movable block 216 slides 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 section 142 is provided as 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 second inelastic pull rope 215 is initially set to a relaxed state. When the squeezing block 174 is squeezed, the squeezing block 174 pulls the second inelastic pull rope to rotate 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 storage spring 214 is contracted and stored. 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.

[0044] In this embodiment, the mounting plate 120 is clamped on the pressure extraction box 110 by setting the reciprocating plate 141, and the reagent tube 151 is manually placed in the suspension clamping ring 150. The cylinder 195 is started, and the cylinder 195 drives the reciprocating plate 141 to move. 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. The needle head 130 at the bottom of the reagent tube 151 moves. When the needle head 130 moves to the orifice of the extraction column 300, the needle head 130 slides and engages with the groove 131, so that it can pass through the orifice 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 interior of 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 disc 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 squeezing block 174 is squeezed by an external force, so that the first return spring 181 on the side of the squeezing block 174 is completely contracted, and the first non-elastic pull rope 180 on the side of the squeezing block 174 slides on the side 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 resets and drives the first non-elastic pull rope 180. The initial state of the second non-elastic pull rope 215 is set to a relaxed state. When the squeezing block 174 is squeezed, the squeezing block 174 pulls the second non-elastic pull rope 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 storage spring 214 is driven to contract and store force. The movable block 216 at the end of the storage spring 214 retracts and hides, and the second protrusion 218 is unobstructed. The pressing plate 175 is ejected from the second fixed groove 172, and the squeezing block 174 presses the disc 137. 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.

[0045] When the suspension clamping ring 150 and the extrusion block 174 are offset, the extrusion block 174 and the movable block 216 are reset. Since the movable block 216 is configured as a wedge-shaped block with an inclined surface facing downward, the second protrusion 218 can smoothly return to its original position.

[0046] In this solution, cylinder 195 drives the movement of reciprocating plate 141 and other components, automating the reagent injection process. 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 of frequent operations and repetitive steps that can easily lead to operator fatigue. Especially when processing a large number of samples, this can affect experimental efficiency and consistency of results, leading to poor detection efficiency.

[0047] Example 2: This example is intended to solve the problem that when performing solid phase extraction, the knob of the adjustment interface 152 must be adjusted twice each time a reagent is added, which greatly reduces the overall processing efficiency. This example is an improvement based on Example 1. For details, please refer to Figure 1-12 A mounting box 111 is installed on the side of the pressure extraction box 110, and a side plate 112 is connected to the top of the mounting box 111. A fixed box 113 is provided on the top of the mounting plate 120. A waste liquid tank 121 is placed inside the pressure extraction box 110. By placing the waste liquid tank 121 inside the pressure extraction box 110, the waste liquid extraction inside the extraction column 300 flows into the inside of the waste liquid tank 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. An adjustment interface 152 is provided 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 adjusted to meet the experimental conditions, thereby speeding up 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 signal sent by the control system, such as electrical signal and gas signal, to change the flow area of the valve, thereby achieving the adjustment of parameters such as pressure and flow.

[0048] 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 to the interior of the regulating interface 152, and a circulation groove 126 is provided in the middle of the rotating ball 125. When the circulation groove 126 overlaps with the notch of the connecting groove 124, the connecting groove 124 and the circulation groove 126 are connected to the interior of the pressure extraction box 110. When the gear 140 rotates, the rotating shaft body 127 in the middle of the gear 140 drives the rotating ball 125 to rotate. When the circulation groove 126 is misaligned with the notch of the connecting groove 124, the connecting groove 124 and the circulation 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 reagents 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 .

[0049] In this embodiment, the adjustment interface 152 is set, and the adjustment interface 152 cooperates with the reciprocating plate 141. 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 rotating 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 are blocked, so that the waste liquid extracted by the extraction column 300 cannot flow 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 and the notch of the connecting groove 124 overlap, and the waste liquid flows to the waste liquid tank 121. Manual operation is easily affected by factors such as fatigue, emotion, and attention, thereby causing operational errors. For example, when closing and opening the adjustment interface 152, manual operation may not guarantee the same force and timing each time. However, this system controls the rotating ball 125 by precisely meshing the gear 140 with the tooth groove, ensuring that the adjustment interface 152 is closed and opened consistently each time, making the reagent reaction time and waste liquid discharge timing more precise.

[0050] Example 3: This example is intended to facilitate solving the problem of needing to adjust the flow rate of the regulating interface 152 according to the reaction conditions when performing solid phase extraction detection. This example is an improvement made on the basis of Example 1. For details, please refer to Figure 1-12 , a first piston cylinder 301 and a second piston cylinder 302 are installed on the mounting plate 120, 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, 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, the first piston disc 305 is slidably connected to the inside of the first piston cylinder 301, a 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.

[0051] 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, and the two tooth groove segments 142 in each group are located on both sides of the adjacent rectangular plate 128.

[0052] In this 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 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. The baffle 304 is driven to move by the transfer of gas between the piston cylinders, which can achieve small and precise adjustment of the extraction flow rate, making the entire solution better.
