Description

TECHNICAL FIELD

[0001] The present application relates to the field of elemental sulfur content determination, in particular to a device for determining elemental sulfur content in building materials. BACKGROUND

[0002] Sulfur content is a harmful substance in construction engineering, such as concrete, and if the sulfur content exceeds the standard, it will affect the strength and durability of the concrete, so it is necessary to determine the sulfur content of building materials in construction engineering.

[0003] At present, the sulfur content is determined by using a fluorescent sulfur determination instrument. The fluorescent sulfur determination instrument uses ultraviolet fluorescence determination principle. The sample is placed in a crucible, and then the crucible enters a high-temperature pyrolysis furnace, and the sample undergoes pyrolysis and oxidation reaction. At a high temperature of about 1000℃, the sample is completely gasified and produces oxidative pyrolysis. The sulfur compounds in it are quantitatively converted into sulfur dioxide. The reaction gas is carried by the carrier gas, and the water in it is removed by a membrane dryer, and then enters the reaction chamber. The sulfur dioxide is irradiated by ultraviolet rays of a specific wavelength, absorbs the rays, and makes some electrons move to a high-energy orbit. Once the electrons return to their original orbit, the excess energy is released in the form of light, which is detected by a photomultiplier tube at a specific wavelength. The emitted fluorescence is completely specific to sulfur and is proportional to the sulfur content in the original sample. After being amplified by a micro-current amplifier and processed by a computer, it can be converted into an electric signal proportional to the light intensity, and the sulfur content of the corresponding sample can be calculated by measuring its size.

[0004] For the above related technology, the inventors found that there are the following defects: when determining the building materials, in order to facilitate measurement, the staff needs to put the weighed sample into the crusher in advance to crush it into multiple pieces, and then put the pieces into the crucible through the bearing disc, but part of the pieces will be left in the crusher, and when the pieces are put into the crucible, part of the pieces will also be left in the bearing disc, which leads to the fact that the sulfur content of part of the pieces cannot be determined, thereby leading to inaccurate determination of the sulfur content of the building materials.

DETAILED DESCRIPTION

[0038] The following description will be made in conjunction with the accompanying drawings Figures 1-5 The application is further described in detail.

[0039] The embodiment of the application discloses a device for measuring elemental sulfur content in building materials. Figure 1 、 Figure 2 The device for measuring elemental sulfur content in building materials comprises a fluorescent sulfur measuring instrument body 2, a crushing mechanism 3 and an oxygen feeding mechanism 4. The crushing mechanism 3 comprises a crushing shell 31, a crushing disc 32, a plurality of crushing knives 33 and a driving source for driving the crushing disc 32 to rotate. The crushing shell 31 is internally provided with a crushing cavity 311, and the side wall of the crushing shell 31 is provided with a crushing opening 312 in communication with the crushing cavity 311. The crushing disc 32 is rotatably installed on the side wall of the crushing cavity 311. The plurality of crushing knives 33 are installed on the outer side wall of the crushing disc 32 in a circumferential direction of the outer side wall of the crushing disc 32. The bottom of the crushing cavity 311 is provided with a discharging groove 313, and the bottom of the discharging groove 313 is provided with a receiving box 6. The side wall of the crushing shell 31 is provided with a discharging opening 314 in communication with the discharging groove 313, and the side wall of the receiving box 6 is provided with a connecting hole in communication with the discharging opening 314.

[0040] The fluorescent sulfur measuring instrument body 2 is internally provided with a crucible groove 22 in communication with a high-temperature pyrolysis furnace 21, and the crucible groove 22 is internally provided with a crucible 7. The bottom of the crucible groove 22 is provided with a lifting piece 8 for driving the crucible 7 to move up and down in a vertical direction. The crushing shell 31 is provided with a feeding pipe 9, and the side wall of the crucible groove 22 is provided with a feeding opening. One end of the feeding pipe 9 is in communication with the connecting hole, and the other end is in communication with the feeding opening.

[0041] The oxygen feeding mechanism 4 comprises an oxygen generator 41 and an oxygen feeding pipeline 42. One end of the oxygen feeding pipeline 42 is connected with the oxygen generator 41, and the other end is in communication with the crushing opening 312.

[0042] Firstly, the driving source is started to drive the crushing knives 33 to rotate. Then, the sample is put into the crushing cavity 311 from the crushing opening 312. After the sample contacts with the crushing knives 33, the sample is impacted to the side wall of the crushing cavity 311 under the pushing force of the crushing knives 33, so that the sample is crushed into a plurality of fragments and falls into the receiving box 6. Then, the oxygen generator 41 is started, so that the oxygen generated by the oxygen generator 41 enters into the crushing opening 312, drives the fragments remaining in the crushing cavity 311 into the receiving box 6, and drives the fragments in the receiving box 6 into the crucible 7 through the feeding pipe 9, thereby effectively reducing the residual fragments and improving the measurement accuracy of the sulfur content in the building materials.

[0043] The fluorescent sulfur measuring instrument body 2 is electrically connected with a computer. The fluorescent sulfur measuring instrument body 2 is internally provided with the high-temperature pyrolysis furnace 21, an oxygen supply system for supplying pure oxygen to the high-temperature pyrolysis furnace 21, and an exhaust system for discharging excess oxygen in the high-temperature pyrolysis furnace 21. The high-temperature pyrolysis furnace 21 is in communication with the crucible groove 22.

[0044] The crushing shell 31 is made of an alloy material, and the crushing opening 312 is arranged on the side wall of the crushing shell 31 and close to the top of the crushing shell 31. The crushing opening 312 is arranged in the crushing shell 31 in a horizontal direction and downwardly inclined, and the end of the crushing opening 312 close to the crushing cavity 311 is the lower end,

[0045] The crushing cavity 311 is a cross-sectionally circular cavity, and the crushing disc 32 is coaxially arranged on the side wall of one side of the crushing cavity 311 and made of an alloy material. The driving source is fixedly arranged outside the crushing shell 31 and is a servo motor, which is coaxially connected to the disc through a shaft coupling.

[0046] Referring to Figure 3 The elemental sulfur content determination device further comprises a controller 1 electrically connected to the driving source, and the controller 1 is in communication connection with a computer, so that a worker can control the controller 1 to start and stop the driving source through the computer.

[0047] The crushing blade 33 is made of an alloy material, and a plurality of crushing blades 33 are arranged on the outer side wall of the crushing disc 32 in a circumferential direction of the outer side wall of the crushing disc 32. In this embodiment, five crushing blades 33 are arranged on the outer side wall of the crushing disc 32. The crushing blade 33 is used to move the sample entering the crushing cavity 311 to the circular side wall of the crushing cavity 311, so that the sample collides with the circular side wall of the crushing cavity 311, thereby breaking the sample into a plurality of fragments.

[0048] Referring to Figure 2 The crushing cavity 311 is arranged on the side wall close to the crushing blade 33 and spaced apart from the outer side wall of the crushing disc 32 in a circumferential direction of the outer side wall of the crushing disc 32. In this embodiment, the crushing groove 315 is arranged on the side wall of one side of the crushing cavity 311. The crushing groove 315 is arranged on the side wall on both sides of the crushing groove 315, and an inclined surface 316 is arranged on the side wall. The end of the inclined surface 316 close to the crushing blade 33 is the lower end, so that the cross-section of the crushing groove 315 is trapezoidal. The sample collides with the crushing groove 315 under the pushing force of the crushing blade 33, thereby improving the crushing effect of the sample. The inclined surface 316 effectively reduces the residue of the fragments in the crushing groove 315, thereby improving the determination accuracy of the sulfur content of the building material.

[0049] The communication part of the crushing cavity 311 and the discharge chute 313 is provided with a filter plate 15, which is located directly below the crushing disc 32. The filter plate 15 is an arc-shaped plate made of alloy material, and the curvature of the arc-shaped plate is matched with the curvature of the circular side wall of the crushing groove 315. The filter plate 15 is provided with filter holes for the passage of crushed blocks. The crushed blocks first pass through the filter holes of the filter plate 15 and then enter the storage box 6, so that the filter plate 15 can alleviate the impact force of the crushed blocks falling into the storage box 6, effectively avoid the production of cracks in the storage box 6 due to long-term impact of the crushed blocks, and cause some crushed blocks to be left in the cracks, thereby improving the accuracy of the determination of the sulfur content of the building materials.

[0050] The side wall of the crushing cavity 311 is provided with a crushing plate 25, which is installed on the side away from the crushing groove 315 and close to the edge of the filter plate 15. The height of the filter plate 15 is such that the crushing knife 33 does not contact the top of the filter plate 15. The filter plate 15 intercepts the crushed blocks with a size greater than the diameter of the filter holes. The crushed blocks intercepted by the filter plate 15 are impacted by the crushing knife 33 and then fall onto the filter plate 15 again, repeating the working process until the crushed blocks can fall into the storage box 6 through the filter holes. The size of the crushed blocks entering the storage box 6 is relatively small, which improves the contact area with the high-temperature pyrolysis furnace 21, shortens the high-temperature pyrolysis time, and thus shortens the overall detection time. It also effectively avoids the incomplete high-temperature pyrolysis of the crushed blocks in the high-temperature pyrolysis furnace 21, thereby improving the accuracy of the determination of the sulfur content of the building materials.

[0051] The side wall of the crushing shell 31 is provided with a mounting hole 317 communicating with the crushing cavity 311. A glass 23 is installed on the crushing shell 31, which seals the opening of the mounting hole 317. The glass 23 is made of colorless and transparent glass 23, and the strength of the glass 23 can resist the impact strength of the crushed blocks. Through the glass 23, the staff can observe whether there are crushed blocks remaining in the crushing cavity 311, which is convenient to observe.

[0052] Referring to Figure 2 , Figure 3 The storage box 6 is made of a box body made of alloy material. The top of the box body is open and hollow. The size of the storage box 6 is matched with the size of the discharge chute 313, and the storage box 6 is slidably connected in the depth direction of the discharge chute 313. A pressure sensor 5 is installed between the bottom of the discharge chute 313 and the storage box 6. The controller 1 is electrically connected with the pressure sensor 5. In this embodiment, the pressure sensor 5 is an electric resistance strain pressure sensor 5. The measurement probe of the pressure sensor 5 is fixedly connected with the storage box 6. The pressure sensor 5 records the weight of the storage box 6 without crushed blocks as the initial zero point. The weight value of the crushed blocks entering the storage box 6 is transmitted to the computer through the controller 1. The staff can calculate the weight of the crushed blocks entering the storage box 6 through the value.

[0053] Referring to Figure 1 , Figure 2 , the crushing shell 31 is hingedly connected with a sealing plate 10 for closing the crushing opening 312, the hinged end of the sealing plate 10 is hingedly connected with the crushing shell 31, and the movable end is provided with a fixing member 11 for fixing the sealing plate 10 to the crushing shell 31, in the embodiment, the hinged end of the sealing plate 10 is located above the movable end, and the fixing member 11 is a U-shaped buckle. A clamping block is fixedly arranged at the bottom of the crushing shell 31 close to the crushing opening 312, and the U-shaped buckle is hingedly connected to the bottom of the sealing plate 10. When the sealing plate 10 closes the crushing opening 312, the worker rotates the U-shaped buckle to make the U-shaped buckle clamped with the clamping block, so as to fix the sealing plate 10 on the crushing shell 31, effectively avoiding that the fragments are discharged from the crushing opening 312 together with the oxygen during the operation of the oxygen generator 41, and improving the determination accuracy of the sulfur content of the building materials.

[0054] The gas generated when the oxygen generator 41 is started is oxygen, and the purity of the oxygen is rich oxygen or pure oxygen. In the embodiment, the oxygen generator 41 generates pure oxygen when it is started.

[0055] Referring to Figure 1 , Figure 2 , the outer side wall of the crushing shell 31 is provided with a gas outlet pipe 12 communicated with the discharge chute 313, the gas outlet pipe 12 is connected with the exhaust system of the fluorescent sulfur determination instrument body 2, and the gas in the gas outlet pipe 12 is discharged through the exhaust system. The gas outlet pipe 12 is provided with a first electromagnetic valve 13 for opening and closing the gas outlet pipe 12. The conveying pipe 9 is a flexible hose made of flexible material, and the conveying pipe 9 is provided with a second electromagnetic valve 14 for opening and closing the conveying pipe 9. The controller 1 is electrically connected with the first electromagnetic valve 13 and the second electromagnetic valve 14, and the worker can use the computer to control the opening and closing of the first electromagnetic valve 13 and the second electromagnetic valve 14 through the controller 1.

[0056] In other embodiments, a filter is arranged at the communication position of the gas outlet pipe 12 and the discharge chute 313, which effectively prevents the fragments from being discharged from the gas outlet pipe 12.

[0057] Before the worker puts the sample into the crushing opening 312, the worker first weighs the sample, then records the weight, and then compares the weight of the sample before crushing with the weight of the fragments after the sample is crushed and enters the storage box 6. When the weight of the fragments after the sample is crushed and enters the storage box 6 is less than the weight of the sample before crushing, it indicates that part of the fragments still remain in the crushing cavity 311. At this time, the oxygen generator 41 is started to oxygenate the crushing cavity 311, so that the fragments remaining in the crushing cavity 311 enter the storage box 6, thereby effectively avoiding the situation that the fragments are missed, and improving the determination accuracy of the sulfur content of the building materials.

[0058] Referring to Figure 2 , Figure 3After the crushing is completed, the staff starts the oxygen generator 41, opens the first electromagnetic valve 13 and closes the second electromagnetic valve 14, the oxygen in the crushing shell 31 moves the residual crushed blocks into the storage box 6, the oxygen is discharged from the air outlet pipe 12 and the air in the crushing shell 31 is discharged from the air outlet pipe 12 together, so that the crushing shell 31 is filled with oxygen, then the first electromagnetic valve 13 is closed and the second electromagnetic valve 14 is opened, the oxygen drives the crushed blocks into the crucible 7, and the excess oxygen is discharged through the high-temperature cracking furnace 21, effectively avoiding the air containing sulfur elements entering the high-temperature cracking furnace 21 through the crucible 7, causing the measured value of the sample sulfur element to be too high, and improving the determination accuracy of the sulfur content of the building material.

[0059] The crucible groove 22 is located directly below the high-temperature cracking furnace 21, and the side wall of the fluorescent sulfur determinator body 2 is provided with a communication hole communicating with the crucible groove 22, and the side wall of the fluorescent sulfur determinator body 2 is hinged with a cabinet door for closing the communication hole, and the staff can open the cabinet door to take the crucible 7 through the communication hole.

[0060] Referring to Figure 1 , Figure 3 , the lifting piece 8 adopts a gas cylinder, the top of the gas cylinder is provided with a fixing seat, the crucible 7 is placed on the top of the fixing seat, and the lifting piece 8 drives the fixing seat and the crucible 7 into the high-temperature cracking furnace 21 together. The lifting piece 8 is electrically connected with the controller 1, and the staff can control the lifting piece 8 to rise and fall through the computer.

[0061] Referring to Figure 1 , Figure 4 , Figure 5 , the side wall of the crucible groove 22 is provided with a baffle 16, and the baffle 16 is a rectangular plate made of alloy material. Two baffles 16 are installed along the length direction of the crucible 7, and the two baffles 16 are respectively hinged with the side walls of the two sides of the crucible groove 22,

[0062] The baffle 16 is provided with a storage shell 17 at the bottom close to the other baffle 16, and the storage shell 17 is a shell made of alloy material. The inside of the storage shell 17 is hollow and the top is open, the side of the storage shell 17 away from the adjacent storage shell 17 is provided with a discharge hole 171, and the top of the baffle 16 is provided with a feeding port 161 communicating with the top opening of the storage shell 17. The storage shell 17 stores combustion-supporting agent, which can fall out of the discharge hole 171 when the baffle 16 is tilted. In this embodiment, the combustion-supporting agent is tungsten particles and tin particles.

[0063] The staff opens the cabinet door before each detection, puts the combustion-supporting agent into the feeding port 161, and makes the combustion-supporting agent enter the storage shell 17. The combustion-supporting agent can lower the melting point of the crushed blocks, so that the crushed blocks are easy to burn, the detection time is shortened, and the detection accuracy of the sulfur content of the building material is improved.

[0064] The storage shell 17 is hinged to the baffle 16 at one end close to the adjacent storage shell 17, and the bottom of the baffle 16 is provided with a first elastic member 18 for driving the movable end of the storage shell 17 to move away from the baffle 16, and the first elastic member 18 is a spring.

[0068] During the movement of the lifting device to the direction of the high-temperature pyrolysis furnace 21, the telescopic rod 24 first tilts the baffle 16, so that the combustion-supporting agent in the storage shell 17 moves from the discharge hole 171 to the limiting plate 19, and falls from the through hole 191 on the limiting plate 19 into the crucible 7 and above the broken pieces, and then the lifting device continues to drive the crucible 7 to move to the direction of the high-temperature pyrolysis furnace 21, so that the crucible 7 is completely located in the high-temperature pyrolysis furnace 21, and the high-temperature decomposition of the broken pieces is better, and the accuracy of the determination of the sulfur content in the building materials is improved.

[0069] The combustion-supporting agent is located above the broken pieces, and the combustion-supporting effect is better than that of the combustion-supporting agent located below the broken pieces.

[0070] The working personnel controls the controller 1 to control the driving source to start through the computer, the driving source drives the rotating disc to rotate, the broken pieces are weighed by the pressure sensor 5 and the weighing value is transmitted to the computer through the controller 1, when the sample completely enters the receiving box 6, the working personnel starts the oxygen generator 41, the oxygen generated by the oxygen generator 41 enters the crushing opening 312 through the oxygen pipeline 42, the broken pieces remaining on the side wall of the crushing cavity 311 and the broken pieces on the broken blade 33 are driven into the receiving box 6, and the broken pieces in the receiving box 6 are driven into the crucible 7 through the material conveying pipe 9, the lifting device 8 is started to extend the crucible 7 into the high-temperature pyrolysis furnace 21, the high-temperature pyrolysis furnace 21 performs high-temperature pyrolysis on the broken pieces in the crucible 7, effectively reducing the broken piece residue, and improving the accuracy of the determination of the sulfur content in the building materials.
