Description

Technical Field

[0001] The invention relates to the technical field of ion exchange resin particle performance testing, in particular to a resin testing device. Background Art

[0002] The particle size and crushing strength of ion exchange resins used in water treatment are important components for evaluating their performance indicators. The particle size distribution is related to the resistance of water passing through the resin layer and the selection of the aperture of the protective net around the resin layer; the crushing strength directly affects the water pressure that the resin particles can withstand. Resin particles with poor crushing strength are easily broken during operation. If the broken resin particles leak through the resin catcher and enter the purified water, it will have a bad impact on the water quality and create serious safety hazards for the safe and stable operation of water-using equipment. Therefore, the accurate and rapid determination of the particle size and crushing strength of ion exchange resin particles plays an important role in the safe and stable operation of subsequent water-using equipment.

[0003] At present, the particle size of ion exchange resin for water treatment is mainly tested by standard sieve; the crushing strength of ion exchange resin is tested according to the DL / T771-2014 method for testing the crushing strength of ion exchange resin; Figure 1 , Figure 1 This is a schematic diagram of a device for measuring the crushing strength of ion exchange resins. A steel column 12 is provided above the resin particles 100. As the amount of water drops dropped into the beaker 11 at the other end of the balance 10 gradually increases, the position of one end of the resin particles 100 gradually rises, so that the pressure of the steel column 12 on the resin particles 100 gradually increases until the resin particles 100 are just crushed. The crushing strength of the resin particles 100 can be determined based on the amount of water drops in the beaker 11 at this moment.

[0004] For the above-mentioned measurement method, only the crushing strength of one resin particle can be measured each time, and the crushing strength measurement speed of each resin particle is slow. It is also necessary to manually calculate the average value after 20 resin particles are tested. The whole process is time-consuming, labor-intensive and inefficient. Summary of the invention

[0005] The purpose of the present invention is to provide a resin testing device, which can improve the crushing strength testing efficiency of resin particles to a certain extent.

[0006] In order to solve the above technical problems, the present invention provides a resin testing device, comprising:

[0007] A separator for separating resin particles from each other;

[0008] An extrusion component is disposed at the position where the resin particles are separated and outputted one by one by the separator, and is used to extrude the resin particles into powder;

[0009] The pressure sensor disposed on the surface of the pressing member pressing the resin particles is used to detect pressure data of the resin particles from being pressed to being crushed, so as to determine the crushing strength of the resin particles according to the pressure data.

[0010] In an optional embodiment of the present application, it also includes a distance measuring sensor arranged on the surface of the extrusion component that extrude the resin particles, for detecting the distance between the two surfaces of the extrusion component that squeeze the resin particles against each other when pressure is started to be applied to the resin particles, so as to determine the particle size of the resin particles.

[0011] In an optional embodiment of the present application, the extrusion component includes a first extrusion component and a second extrusion component, wherein the first extrusion component is provided with a groove structure that can accommodate the resin particles to fall into, and the second extrusion component is provided with a protrusion structure that can be inserted into the groove structure and extrude the resin particles.

[0014] In an optional embodiment of the present application, the pressure sensor is arranged at the tooth tip portion and tooth groove portion of the first gear structure and the second gear structure.

[0015] In an optional embodiment of the present application, a high-pressure water spray gun is further included to clean the surface of the extrusion component that extrude the resin particles to remove the crushed residues of the resin particles.

[0016] In an optional embodiment of the present application, the separator includes a cylindrical shell and a rotating blade arranged inside the cylindrical shell; wherein the inner diameter of the cylindrical shell is equal to the diameter of the rotating surface of the rotating blade; and a separation inlet and a separation outlet are also provided on the cylindrical shell, and the separation inlet and the separation outlet are respectively located above and below the rotating surface of the rotating blade.

[0017] In an optional embodiment of the present application, a separation detection device is further included, which is used to detect whether the resin particles output from the separator are separated one by one and fall into the extrusion component.

[0018] In an optional embodiment of the present application, the separation detection device includes an ultrasonic induction detector for sending ultrasonic waves to the space area between the separator and the extrusion component to determine whether the resin particles output from the separator fall into the extrusion component one by one.

[0019] In an optional embodiment of the present application, a sample tank is further included. The sample tank is a funnel structure for carrying the resin particles to be tested and outputting the resin particles to the separator.

[0020] A resin testing device provided by the present invention comprises: a separator for separating resin particles from each other; an extrusion component arranged at a position where the separator separates and outputs resin particles one by one, and used to extrude the resin particles until they are crushed; and a pressure sensor arranged on the surface of the extrusion component that extrude the resin particles, and used to detect pressure data of the resin particles during the process from being extruded to being crushed, so as to determine the crushing strength of the resin based on the pressure data.

[0021] The resin testing device in the present application separates the resin particles from each other through a separator, and then squeezes the separated resin particles through an extrusion component in turn until they are crushed, and a pressure sensor is arranged on the extrusion component, so as to realize the pressure during the entire process of the resin particles being squeezed to crush, thereby determining the pressure that the resin particles are subjected to when they are crushed and realizing the crushing strength test of the resin particles.

[0022] In order to more clearly illustrate the embodiments of the present invention or the technical solutions of the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0025] Figure 3 A schematic structural diagram of an extrusion component provided in an embodiment of the present application. DETAILED DESCRIPTION

[0026] Reference Figure 1 In the process of measuring the crushing strength of the resin particles 100 according to the DL / T 771-2014 method for measuring the crushing strength of ion exchange resins, it is necessary to manually drip water drops into the beaker 11 drop by drop, and after the two ends of the balance stabilize, read and record the readings of the balance 10, and continue to drip water drops into the beaker 11 until the resin particles 100 are squeezed and crushed by the steel column 12. The whole process requires manual operation, and in order to ensure the accuracy of the measured squeezing force strength, the increment of the squeezing force applied by the steel column 12 to the resin particles 100 caused by each additional drop of water in the beaker 11 is very small, which makes the whole measurement process relatively long; on this basis, it is also necessary to complete the crushing strength measurement of multiple resin particles 100 and find the average, which further makes the whole measurement process time-consuming and inefficient.

[0027] To this end, the present application provides a technical solution that can realize automated measurement of resin particles, thereby improving the efficiency of measuring the crushing strength of resin particles.

[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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 work are within the scope of protection of the present invention.

[0029] like Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the structure of the resin testing device provided in the embodiment of the present application. Figure 3 A schematic diagram of the structure of an extrusion component provided in an embodiment of the present application. The resin testing device may include:

[0030] A separator 21 for separating the resin particles 100 from each other;

[0031] An extrusion component 22 is provided at a position where the resin particles 100 are separated and outputted one by one by the separator 23, and is used to extrude the resin particles 100 into powder;

[0032] The pressure sensor disposed on the surface of the pressing member 22 pressing the resin pellets 100 is used to detect pressure data of the resin pellets 100 during the process from being pressed to being crushed, so as to determine the crushing strength of the resin pellets 100 based on the pressure data.

[0033] The resin testing device in this embodiment includes two parts, namely, a separator 21 and an extrusion component 22, wherein the separator 21 can realize automatic separation of a large number of resin particles 100 so that each resin particle 100 can fall into the extrusion component 22 one by one, and then be crushed by the extrusion component 22, and the pressure borne by the resin particle 100 at the moment of being crushed is the crushing strength of the resin particle 100. Because the resin particles 100 fall into the extrusion component 22 one by one, the extrusion of the resin particles 100 by the extrusion component 22 is completed by extruding each resin particle 100 individually, thereby realizing the individual measurement of the crushing strength of each resin particle 100.

[0034] It is understandable that in order for the extrusion component 22 to extrude the resin particles 100, it is necessary to have two relatively movable extrusion surfaces; for this purpose, the extrusion component 22 in this embodiment should be a component connected to a drive motor, which can drive the distance between the extrusion surfaces of the extrusion component 22 to change, thereby achieving extrusion and crushing of the resin particles 100 located between the two extrusion surfaces.

[0035] On this basis, a pressure sensor is also arranged on the extrusion surface of the extrusion component 22. When the driving component drives the extrusion surface of the extrusion component 22 to extrude the resin particles 100, the extrusion force on the resin particles 100 gradually increases as the extrusion process proceeds; the corresponding pressure data measured by the pressure sensor also gradually increases. Based on the principle of action and reaction, the pressure data measured by the pressure sensor is the pressure magnitude borne by the resin particles 100. When the resin particles 100 are crushed, the pressure data measured by the pressure sensor will inevitably produce a large jump, and the pressure data at the moment of the jump corresponds to the crushing strength of the resin particles 100, thus realizing the measurement of the crushing strength of the single-particle resin particles 100. In this way, the crushing strength of each resin particle 100 falling into the extrusion component 22 can be measured in the same way; in order to ensure the accuracy of the crushing strength finally measured, the average crushing strength of multiple resin particles 100 with the same particle size can be used as the crushing strength of the resin particles 100 corresponding to the particle size.

[0036] Based on the above discussion, although the extrusion component 22 also extrude each resin particle 100 individually, because the extrusion component 22 is provided with a pressure sensor, the force applied by the extrusion component 22 to the resin particles 100 can be detected in real time, and the resin particles 200 can be squeezed to the crushing process, which can be completed in one time. Compared with dripping water droplets into the beaker 11 drop by drop, the time consumed is greatly reduced, and the extrusion component 22 automatically extrude the resin particles 100 and measure the extrusion force during the whole process, and no manual operation is required, thereby saving time and effort in the crushing strength test process of the resin particles 100.

[0037] In addition, in order to process and display the pressure data corresponding to each resin particle 100, the pressure sensor and the host device can also be connected, and the pressure data of each resin particle 100 can be recorded in turn by the host device. Through the display, the staff can more intuitively see the measurement results of the crushing strength of each resin particle 100.

[0038] The separator 21 and the extrusion component 22 in the present application may have a variety of different structural forms. In an optional embodiment of the present application, the separator 21 may include:

[0039] A cylindrical shell 211 and a rotating blade 212 arranged inside the cylindrical shell 211; wherein the inner diameter of the cylindrical shell 211 is equal to the rotating surface diameter of the rotating blade 212; and a separation inlet 213 and a separation outlet 314 are also provided on the cylindrical shell 211, and the separation inlet 213 and the separation outlet 214 are respectively located above and below the rotating surface of the rotating blade 212.

[0040] Reference Figure 2 ,exist Figure 2 In the embodiment shown, the cylindrical housing 211 is arranged with its central axis in a horizontal direction. At the same time, the rotation central axis of the rotating blade 212 in the cylindrical housing 211 coincides with the central axis of the cylindrical housing 211, and the rotation surface of the rotating blade 212 is directly equal to the inner diameter of the cylindrical housing 211; and the cylindrical housing 211 is provided with a separation inlet 213 and a separation outlet 214 at its upper and lower parts respectively.

[0041] The separation inlet 213 is the entrance for the resin particles 100 to be measured to enter the separator 21. It can be set at the highest point on the cylindrical shell 212, or at least at a position more than half of the height of the cylindrical shell 211 in the vertical direction, as long as the resin particles 100 can be prevented from being discharged from the separation inlet 213. The separation outlet 214 is the outlet for the resin particles 100 to be output from the separator 21 and fall into the extrusion component 22; for the separation outlet 214, it is obvious that it should be the position facing the extrusion component 22 to receive the resin particles 100. Generally speaking, it can be set at the lowest point on the cylindrical shell 211 of the separator 21, or close to the lowest point, at least at a position less than half of the height of the cylindrical shell 211 in the vertical direction, to ensure that the resin particles 100 can be discharged from the separation outlet 214.

[0042] When the resin particles 100 enter the cylindrical shell 211 through the separation inlet 213 of the separator 21, they rotate inside the cylindrical shell 211 along with the rotating blades 212. When the resin particles 100 rotate to the upper half of the cylindrical shell 211 along with the rotating blades 212, the resin particles 100 fall into the groove between two adjacent rotating blades 212 due to the gravity of the resin particles 100, thereby preventing the resin particles 100 from being discharged from the separation inlet 214; when the resin particles 100 rotate to the lower half of the cylindrical shell 211 along with the rotating blades 212, the resin particles 100 fall on the inner surface of the cylindrical shell 211 and rotate along the inner surface of the cylindrical shell 211 due to the gravity of the resin particles 100, and the separation outlet 214 is provided on the inner surface of the cylindrical shell 211, so that the resin particles 100 can be discharged from the separation outlet 214 when passing through the separation outlet 214. However, in order to achieve the separation and discharge of each resin particle 100, that is, only one resin particle 100 is discharged from the separation outlet 214 each time, firstly, the aperture size of the separation outlet 214 can be reasonably set, at least requiring the aperture size of the separation outlet 214 to be smaller than the sum of the diameters of any two resin particles 100, so that the separation outlet 214 can only discharge one resin particle 100 at a time. On this basis, the rotation speed of the rotating blade 212 can also be reasonably controlled. When multiple resin particles 100 pass through the location of the separation outlet 214, when one of the resin particles 100 is discharged from the separation outlet 214, the second resin particle 100 is driven and taken away by the rotating blade 212 before it can be discharged from the separation outlet 214. Even if one of the multiple resin particles 100 between the adjacent rotating blades 212 is discharged from the separation outlet 214 again, there is a certain time difference between the discharge of the two resin particles 100, which does not affect the independent extrusion of the two resin particles 100 by the extrusion component 22.

[0043] Of course, the separator 21 is not limited to Figure 2 The arrangement shown in the figure, for example, the central axis of the cylindrical shell 211 can also be arranged in the vertical direction, or even be arranged at an angle with the horizontal direction and the vertical direction, etc., which does not affect the implementation of this embodiment. Figure 2 The cylindrical structure 211 shown, for example, can also be directly set as a device with an inverted cone structure at the bottom, and a port with controllable opening and closing is set at the bottom. By controlling the opening and closing time of the port, the port is opened each time for only enough time for one resin particle 100 to be discharged, and the mutual separation of each resin particle 100 can be achieved to a certain extent. Of course, in actual applications, there can be other separators 21 for separating the resin particles 100 from each other, which are not listed one by one in this application.

[0044] Furthermore, in order to ensure that the resin particles 100 discharged from the separator 21 are discharged one by one, in an optional embodiment of the present application, a separation detection device may be further included, and the separation detection device is used to detect whether the resin particles 100 output from the separator 21 fall into the extrusion component 22 one by one. In other words, the separation detection device is used to detect that only one resin particle 100 is discharged from the separator 21 each time.

[0045] The separation detection device may use an ultrasonic induction detector for sending ultrasonic waves to the space between the separator 21 and the extrusion component 22 to determine whether the resin particles 100 output from the separator 21 are separated one by one and fall into the extrusion component 22 .

[0046] The ultrasonic induction detector can send ultrasonic signals to the space area between the separation outlet 214 and the extrusion component 22 of the separator 21. Obviously, when resin particles 100 are discharged from the space area between the separation outlet 214 and the extrusion component 22, the ultrasonic signals can be reflected back by the resin particles 100, and when only one resin particle 100 and two or more resin particles 100 are discharged from the separation outlet 214, the reflected ultrasonic signals are completely different. Therefore, this can be used as a basis for judging whether the resin particles 100 are discharged separately one by one, and the separation detection of the resin particles 100 is realized according to the ultrasonic signals reflected back by the ultrasonic waves. When the ultrasonic induction detector detects that multiple resin particles 100 are separated and discharged from the separator 21 at the same time, a warning can be issued to remind the staff to appropriately increase the rotation speed of the rotating blade 212 in the separator 21; and when the ultrasonic induction detector fails to detect the resin particles 100 being discharged from the separator for a long time, an alarm can also be issued to remind the staff to appropriately reduce the rotation speed of the rotating blade 212 to achieve smooth separation and discharge of the resin particles 100 from the separator 21.

[0047] Of course, the separation detection device is not limited to the above-mentioned ultrasonic induction detector. Devices such as image detectors can also be used to continuously capture and shoot images of the spatial area between the separator 21 and the extrusion component 22, and perform image analysis to determine the number of resin particles 100 contained in the image. It can also detect the number of resin particles 100 discharged each time. There are other similar methods, which are not listed one by one in this embodiment.

[0048] In addition, in order to avoid manually adding resin particles 100 into the separation inlet of the separator 21, in another optional embodiment of the present application, a sample slot 23 may also be included. The sample slot 23 is a funnel structure for carrying the resin particles 100 to be tested and outputting the resin particles to the separator 21.

[0049] Reference Figure 2 The output port of the sample tank 23 faces the separation inlet 214 of the separator 21 . It is conceivable to directly connect the output port of the sample tank 23 and the separation inlet 214 of the separator 21 . In short, the two can be connected to each other.

[0050] In order to prevent the resin particles 100 in the sample tank 23 from being blocked at the output port of the sample tank 23 , a vibrator may be further provided on the sample tank 23 to facilitate the resin particles 100 to flow smoothly into the separator 21 .

[0051] Based on the above embodiments, refer to Figure 2 and Figure 3In another optional embodiment of the present application, the extrusion component 22 for extruding and crushing the resin particles 100 may include:

[0052] The first extrusion piece 31 and the second extrusion piece 32 , wherein the first extrusion piece 31 is provided with a groove structure 311 for accommodating the resin particles 100 to fall into, and the second extrusion piece 32 is provided with a protrusion structure 321 that can be inserted into the groove structure 311 and extrude the resin particles 100 .

[0053] The extrusion component 22 in this embodiment includes two parts, namely a first extrusion component 31 and a second extrusion component 32 that can move relative to each other. When the resin particles 100 fall into the position between the first extrusion component 31 and the second extrusion component 32, the resin particles 100 can be extruded by driving the first extrusion component 31 and the second extrusion component 32 to move relative to each other through a driving component.

[0054] Further considering that the resin particles 100 are spherical particles, in order to prevent the resin particles 100 from rolling during the extrusion process, a groove structure 311 can be set on the surface of the first extrusion member 31 that extrude the resin particles 100, so that the resin particles 100 discharged from the separator 21 can fall into the groove structure 311. On this basis, a protrusion structure 321 is also set on the second extrusion member 32. When the first extrusion member 31 and the second extrusion member 32 are driven to move relative to each other, the protrusion structure 321 can be inserted into the groove structure 311, so that the protrusion structure 321 and the groove structure 311 can cooperate with each other to extrude and crush the resin particles 100.

[0055] It can be understood that, for the first extrusion piece 31 and the second extrusion piece 32, the tip surface where the protrusion structure 321 and the resin particle 100 contact each other is also the extrusion surface for extruding the resin particle 100; and for the groove structure 311, the groove bottom surface of the groove structure 311 is the extrusion surface. Therefore, in practical applications, the tip surface of the protrusion structure 321 and the groove bottom surface of the groove structure 311 can be provided with an upper pressure sensor, or the upper pressure sensor can be provided with an upper pressure sensor on one of the two surfaces, and the pressure data of the resin particle 100 in the whole process of being extruded to crushed can be detected, thereby realizing the measurement of the crushing strength.

[0056] In order to further improve the working efficiency of the crushing strength measurement of the resin particles 100, in another optional embodiment of the present application, it may further include:

[0057] The extrusion component 22 includes a first gear structure 221 and a second gear structure 222 that can mesh with each other;

[0058] The position where the first gear structure 221 and the second gear structure 222 mesh with each other is located below the position where the resin particles 100 are output from the separator 21, so that the resin particles 100 output from the separator 21 fall between the tooth tips 224 and the tooth grooves 223 at the position where the first gear structure 221 and the second gear structure 222 mesh with each other, and squeeze the resin particles 100 as the first gear structure 221 and the second gear structure 222 rotate.

[0059] For the first gear structure 221 and the second gear structure 222 in this embodiment, the tooth groove 223 between the tooth tips 224 on each gear structure is equivalent to the groove structure 311 of the first extrusion member 31 in the above embodiment, and the tooth tip 224 engaged in the tooth groove 223 is equivalent to the protrusion structure 321 of the second extrusion member 32 in the above embodiment.

[0060] On this basis, because the first gear structure 221 and the second gear structure 222 are each provided with a plurality of tooth tips 224 and tooth grooves 223 that can mesh with each other, the first gear structure 221 and the second gear structure 222 are respectively driven by the driving motor to rotate, so that the resin particles 100 discharged from the separator can fall into each tooth groove 223 in turn, and are gradually squeezed by the corresponding tooth tips 224. In this process, there can often be a plurality of tooth grooves 223 between the first gear structure 221 and the second gear structure 222, each filled with a resin particle 100, so that the plurality of resin particles 100 can be squeezed and crushed independently at the same time and the crushing strength can be measured.

[0061] In order to ensure that the resin particles can be better inserted into the tooth groove 223, the spacing between the first gear structure 221 and the second gear structure 222 can be adjusted based on the particle size of the resin particles 100 to avoid the resin particles 100 being too large or too small in size and affecting the tooth tip 224 and the tooth groove 223 from squeezing the resin particles 100.

[0062] In actual applications, in order to simultaneously measure the pressure data of the resin particles 100 in each tooth groove 223, pressure sensors can be set at the ends of the tooth tips 224 and the bottoms of the tooth grooves 223 on the first gear structure 221 and the second gear structure 222. It is also possible to consider setting pressure sensors only at the ends of the tooth tips 224 or the bottoms of the tooth grooves 223. Based on the independent measurement of each pressure sensor, the independent measurement of the pressure data of each resin particle 100 can be achieved.

[0063] It is understandable that the independent detection of the crushing strength of the plurality of resin particles 100 is not limited to the first gear structure 31 and the second gear structure 32 in the above embodiment. Figure 3In the illustrated embodiment, the extrusion component 22 may also be a first extrusion component 31 having a row of groove structures 311 and a corresponding second extrusion component 32 having a row of protrusion structures 321, and the separator 21 also has a row of separation outlets 214, which discharge the resin particles 100 directly into each groove structure 311, and each second extrusion component 32 is driven by a driving motor to drive each protrusion structure 321 back and forth to extrude the first extrusion component 31 and the groove component 311 until all the resin particles 100 are crushed, and then drive the protrusion structure 321 to move away from the groove component 311 until each groove structure 311 is replaced with a new resin particle 100, and then repeat the above operation, thereby realizing the synchronous determination of multiple resin particles 100, thereby improving the test efficiency.

[0064] In addition, in another optional embodiment of the present application, the groove structures 311 provided on the first extrusion member 31 may be two rows or multiple rows, and each groove structure 311 is alternately located in sequence directly below the separation outlet 214 of the separator 21 and the protrusion structure 321, thereby realizing that each row of groove structures 311 alternately carries the resin particles 100 and cooperates with the crushing and measurement of the resin particles 100. Of course, the extrusion member 22 in the present application may also include a variety of other different structural forms, which are not listed one by one in the present application.

[0065] In addition, after the resin particles 100 in the extrusion component are extruded and crushed, the residue of the resin particles 100 will inevitably be generated. For this reason, in another optional embodiment of the present application, a high-pressure water spray gun is further provided to clean the surface of the extrusion component 22 extruding the resin particles 100 to remove the residue of the crushed resin particles 100.

[0066] It is understandable that when the groove structure 311 on the extrusion component 22 needs to be flushed by a high-pressure water spray gun, the groove structure 311 can be arranged with the notch tilted downward so that the water sprayed by the high-pressure water spray gun and the resin particle 100 residue can be better removed from the groove structure 311.

[0067] Of course, for Figure 2 In the illustrated embodiment, because the extrusion component 22 is a two-gear structure, each tooth groove 223 can be rotated to a position with the notch facing downward after extruding the resin particles 100, so that the water spray gun can clean the tooth groove 223.

[0068] As described above, the resin particles 100 include a variety of different particle sizes. The crushing strength of the resin particles 100 of different particle sizes should be different, and the particle size of the resin particles 100 is also one of the important performance indicators that need to be measured. For this reason, the present application may further include a particle size detector for measuring the particle size of the resin particles 100.

[0069] There may be a variety of different optional forms for the particle size detector. In an optional embodiment of the present application, the particle size measuring device may be a distance measuring sensor, which is disposed on the extrusion surface of the extrusion component 22 that extrude the resin particles 100. The distance measuring sensor is used to detect the distance when the two extrusion surfaces of the extrusion component 22 just begin to apply extrusion force to the resin particles 100, and the distance is used as the particle size of the resin particles 100.

[0070] It can be understood that when the two extrusion surfaces of the extrusion component 22 just begin to apply extrusion force to the resin particles 100, it is obvious that the two extrusion surfaces should be exactly tangent to the surface of the resin particles, and the two tangent points are the two end points of a diameter of the resin particles 100. Then the distance between the two extrusion surfaces is equal to the resin particles 100. When the distance between the two extrusion surfaces is measured at this time, the particle size of the resin particles 100 can be determined.

[0071] To this end, distance measuring sensors for mutual positioning and distance measurement can be set on the two extrusion surfaces that cooperate with each other to extrude the same resin particle 100, and the distance between the two extrusion surfaces can be detected in real time. At the same time, combined with the pressure sensors on the two extrusion surfaces, when the extrusion force measured by the pressure sensor increases from zero to a certain value, or from a constant pressure to a moment when the pressure starts to increase, it is the moment when the two extrusion surfaces simultaneously start to extrude and apply pressure to the resin particle 100, and the distance between the two extrusion surfaces measured by the distance measuring sensor corresponding to this moment also corresponds to the particle size of the resin particle 100.

[0072] The distance measuring sensor can be in various forms. For example, an RFID radio frequency receiver and a transmitter are respectively arranged on the two extrusion surfaces of the extrusion component, and the distance between the two extrusion surfaces is determined based on the distance between the RFID radio frequency receiver and the transmitter. Of course, UWB positioning technology can also be used to measure the relative distance between the two extrusion surfaces to a fixed position point, and then determine the distance between the two extrusion surfaces through mathematical calculation. The calculation process is common knowledge of UWB positioning technology and will not be described in detail here.

[0073] Of course, in another optional embodiment of the present application, it is also possible to consider using image recognition to capture images of the resin particles 100, and to detect the particle size of the resin particles 100 through image recognition technology, etc., which can achieve the particle size measurement of the resin particles 100 in the present application.

[0074] In addition, in another optional embodiment of the present application, it is also possible to consider setting the separation outlet 214 of the separator 21 as an outlet with adjustable aperture size, first allowing only resin particles 100 with small particle sizes to pass through, and when the resin particles 100 with small particle sizes are completely discharged and enter the extrusion component 22 to complete the measurement of the crushing strength, then gradually increase the aperture of the separation outlet 214. In this way, the size of the resin particles 100 discharged within a certain fixed time period can be determined by the aperture size of the separation outlet 214 corresponding to that moment.

[0075] As mentioned above, for the test device in the present application, it can be configured with a host device. Then, in actual applications, various devices such as the separator 21, the extrusion component 22, the separation detection device and even the ultrasonic induction detector can communicate with the host device, and the host device can realize the start and stop control and parameter setting of the operation of each different device component. For example, the rotation speed of the rotating blade 212 in the separator 21 can be controlled by the host device, and the driving speed of the driving motor of the extrusion component 22 can also be controlled by the host device. The host device can also collect detection data collected by sensing devices such as pressure sensors and ranging sensors, etc., which are not listed one by one in this embodiment.

[0076] In addition, the sample tank 23, separator 21, extrusion component 22 and other components that come into direct contact with the resin particles 100 can be made of acid-resistant, alkali-resistant, wear-resistant, pressure-resistant and leak-proof materials.

[0077] In summary, the resin testing device in the present application is provided with a separator for separating resin particles one by one, and an extrusion component for crushing the resin particles. The separator is used to discharge the resin particles into the extrusion component one by one, and the extrusion component is used to independently extrude and crush each discharged resin particle, and a pressure sensor is used to measure the pressure data of the resin particles at the moment of being crushed, thereby realizing the measurement of the resin particles. The whole process does not require excessive operation by the staff, and is fully automated. The crushing process of each resin particle is fast and efficient, thereby improving the efficiency of the crushing strength measurement of the resin particles.
