Description

Technical Field

[0001] The present invention relates to the technical field of chemical test analysis, in particular to a feeding structure of a chemical test analyzer. Background Art

[0002] Particle size and particle analysis are of central importance in the fields of chemical engineering, materials, medicine, energy, and other fields, directly impacting product performance, process optimization, and quality control. Common tools for particle size and particle analysis include laser particle size analyzers and high-speed camera dynamic image analysis. Laser particle size analyzers include wet laser particle size analyzers for suspensions and emulsions, and dry laser particle size analyzers for dry particles and powders. Dry laser particle size analyzers are particle measurement devices based on the principles of laser scattering and diffraction. They measure the intensity distribution of scattered light from a particle group to reveal the particle size and distribution.

[0003] Currently, dry laser particle size analyzers require the particulate material to be dried and pre-treated before use. The material is then evenly dispersed and discharged through a hopper and a vibrating distribution trough. The sensor (optical detection system) accurately captures the scattered light intensity distribution through a multi-angle detector array. This is followed by data processing and result output. That is, the scattered light intensity distribution data collected by the sensor is inverted into a particle size distribution through an algorithm. However, current granular materials are all dried in a centralized manner, with a large drying volume. They cannot be dried uniformly within the specified drying time, and there is still a clumping phenomenon. If the granular materials are analyzed and tested in a clumping state, the test results will be inaccurate. Secondly, due to the centralized and continuous discharge through the discharge hopper, a lot of material is accumulated at the discharge port, so a longer vibration distribution trough is required for vibration dispersion and discharge. The equipment occupies a large area and has high equipment cost. At present, all materials go through four steps: drying pretreatment, discharge hopper, vibration distribution trough and discharge test. The test process is cumbersome and the test efficiency is low. Furthermore, although there is a vibration distribution trough for vibration dispersion and discharge, there is still material accumulation and overlapping discharge. If the materials overlap during the analysis test, the granular form of the overlapping part cannot be identified, resulting in inaccurate test results.

[0004] Therefore, in order to optimize the test process and improve the accuracy of the test results, the present invention provides a feeding structure of a chemical test analyzer. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art and to propose a feeding structure for a chemical test analyzer.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A feeding structure of a chemical test analyzer comprises an analyzer body, wherein a heating mechanism is provided on the analyzer body, a diffusion mechanism is provided below the heating mechanism, and a feeding mechanism is provided below the diffusion mechanism.

[0008] The heating mechanism includes a support assembly arranged on the analyzer body and a heating assembly arranged on the support assembly. The support assembly is used to provide support for the heating assembly and to load the granular material.

[0010] The unloading mechanism includes a support frame fixedly connected to the top wall of the analyzer body and a dispersion component and an anti-blocking component arranged on the support frame. The dispersion component is used to further disperse the particulate material. The dispersion component drives the anti-blocking component through a deflection action. The cooperation between the dispersion component and the anti-blocking component helps the particulate material to form a single particle flow.

[0011] In the above-mentioned feeding structure of a chemical test analyzer, the support assembly includes a support column, and the top wall of the analyzer body is fixedly connected to a plurality of support columns distributed in a matrix shape, the top walls of the plurality of support columns are commonly fixedly connected to a heating bucket, and the middle part of the heating bucket is connected to a support member through a plate fixed to the inner wall, and a rotating seat is passed through the internal rotation of the support member.

[0012] In the above-mentioned feeding structure of a chemical test analyzer, the heating assembly includes a fan-shaped heating element, and the inner wall of the heating bucket and the outer wall of the support element are connected together by multiple torsion spring rods, and multiple fan-shaped heating elements distributed along the circumferential direction are rotatably connected. The multiple fan-shaped heating elements together form a disc shape, and an electric heating wire is installed inside the fan-shaped heating element.

[0013] In the above-mentioned feeding structure of a chemical test analyzer, a plurality of fan-shaped heating elements are fixedly connected to the bottom wall near the edge of the heating bucket with a protrusion one, the outer wall of the rotating seat is fixedly connected to a cross bar arranged below the fan-shaped heating element, and the end of the cross bar away from the rotating seat is fixedly connected to a protrusion two adapted to the protrusion one.

[0014] In the above-mentioned feeding structure of a chemical test analyzer, a trapezoidal inclined plate is fixedly connected between the heating bucket and the support frame, the trapezoidal inclined plate on the left is inclined toward the lower right, and the trapezoidal inclined plate on the right is inclined toward the lower left. The guide bar group includes multiple guide bars, which diffuse the particulate material on the surface of the trapezoidal inclined plate from the middle to the front and rear.

[0015] In the above-mentioned feeding structure of a chemical test analyzer, the dispersion component includes a driving part, and the bottom wall of the rotating seat is coaxially fixedly connected with the driving part. The driving part consists of a shaft connected to the rotating seat and a plurality of wedge blocks fixed along the circumferential direction on the bottom wall of the shaft.

[0016] In the above-mentioned feeding structure of a chemical test analyzer, two plates are symmetrically arranged on the support frame and are connected by a torsion spring rod. The outer walls of the two plates on the side close to each other are fixedly connected with multiple rows of blocks distributed at equal intervals above and below, and the two adjacent rows of blocks are staggered front and back.

[0017] In the above-mentioned feeding structure of a chemical test analyzer, the upper part of the outer wall on the side where the two plate surfaces are close to each other is fixedly connected with a wedge block 1 that is compatible with the wedge block 2, and the side of the wedge block 1 away from the plate surface is inclined, and the top wall of the wedge block 1 is fixed with a triangular block to prevent the granular material from staying.

[0018] In the above-mentioned feeding structure of a chemical test analyzer, the anti-blocking component includes a fixed plate, the bottom walls of the two plate surfaces are fixedly connected to the fixed plate, and the side walls of the two fixed plates close to each other are connected to an L-shaped movable plate by sliding back and forth through a spring, and the two L-shaped movable plates are symmetrical in center.

[0019] In the above-mentioned feeding structure of a chemical test analyzer, the rear of the left L-shaped movable plate and the front of the right L-shaped movable plate are fixedly connected with protrusion three, and the lower side wall of the support frame is fixedly connected with protrusion four corresponding to protrusion three.

[0020] Compared with the existing technology, the advantages of the present invention are:

[0021] 1. Through the coordination of the support assembly and the heating assembly, multiple fan-shaped heating elements alternately dry and discharge the materials. The fan-shaped heating elements perform tilt changes at the same angle and fixed time to evenly release the granular materials and improve the continuity of the test analysis. This eliminates the need for pre-treatment steps of centralized drying before testing, simplifies the test process, and helps avoid the situation where a large amount of drying is required during pre-treatment, resulting in uneven drying within the prescribed drying time and the presence of agglomerates, which in turn causes inaccurate test results.

[0022] 2. Through the coordination of the diffusion mechanism and the discharge mechanism, double dispersion treatment is carried out in the process of vertical falling of the granular material, with high dispersion efficiency and small equipment occupation area; the granular material scattered on the surface of the trapezoidal inclined plate with narrow upper part and wide lower part is diffused from the middle to the front and rear by the guidance of the guide bar group, and the lower part of the two trapezoidal inclined plates distributed symmetrically on the left and right forms a strip space facing front and back for the granular material to be discharged. After falling on the plate surface, it is blocked by the block for further dispersion.

[0023] 3. Through the coordination of the dispersion component and the anti-blocking component, the deflection angle of the plate surface can change the position of the granular material falling above the plate surface. The granular material between the gaps of the two fixed plates is driven back and forth alternately by the two L-shaped movable plates, which helps the granular material to form a single particle flow, reduces the situation of granular material stacking and feeding, and improves the accuracy of the test results.

[0036] 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.

[0037] Reference Figure 1 A feeding structure of a chemical test analyzer includes an analyzer body 1, a heating mechanism 2 is provided on the analyzer body 1, a diffusion mechanism 3 is provided below the heating mechanism 2, and a feeding mechanism 4 is provided below the diffusion mechanism 3.

[0038] The granular material passes through the heating mechanism 2, the diffusion mechanism 3 and the feeding mechanism 4 in sequence. After being heated, evenly released and dispersed, it enters the analyzer body 1 and generates scattered light when passing through the laser beam. The detector records the light intensity distribution. The software converts the scattered light intensity distribution into volume / number weighted particle size distribution and outputs the particle size distribution curve, specific surface area, average particle size and other results.

[0039] Reference Figures 1 to 3 The heating mechanism 2 includes a support component 21 arranged on the analyzer body 1 and a heating component 22 arranged on the support component 21. The support component 21 is used to provide support for the heating component 22 and is used for loading the particulate material. The heating component 22 is used to heat the particulate material layer by layer and evenly release the particulate material.

[0040] Reference Figures 2 to 4 The support assembly 21 includes a support column 211. The top wall of the analyzer body 1 is fixedly connected to multiple support columns 211 distributed in a matrix shape. The top walls of the multiple support columns 211 are commonly fixedly connected to a heating bucket 212. The middle part of the heating bucket 212 is connected to a support member 213 through a plate fixed to the inner wall. The internal rotation of the support member 213 is penetrated by a rotating seat 214.

[0041] Reference Figures 2 to 4 The heating assembly 22 includes a fan-shaped heating element 221. The inner wall of the heating bucket 212 and the outer wall of the support member 213 are rotatably connected to a plurality of fan-shaped heating elements 221 distributed along the circumferential direction through a plurality of torsion spring rods. The plurality of fan-shaped heating elements 221 together form a disc shape, and an electric heating wire is installed inside the fan-shaped heating element 221; the bottom walls of the plurality of fan-shaped heating elements 221 are fixedly connected to a protrusion 1 222 near the edge of the heating bucket 212; the outer wall of the rotating seat 214 is fixedly connected to a cross bar 223 arranged below the fan-shaped heating element 221, and the end of the cross bar 223 away from the rotating seat 214 is fixedly connected to a protrusion 2 224 adapted to the protrusion 1 222.

[0042] First, the granular material is placed in the heating bucket 212, and the electric heating wire in the fan-shaped heating element 221 is heated to dry the granular material near the top surface of the fan-shaped heating element 221. The top of the rotating seat 214 is detachably connected to the output end of the external motor. After the top of the rotating seat 214 is connected to the motor, the output end of the motor rotates to drive the rotating seat 214 and the cross bar 223 to rotate at a uniform speed. The cross bar 223 drives the protrusion 224 to rotate, pushing the protrusion 1 222 during the rotation. The protrusion 1 222 is pushed and drives the corresponding The fan-shaped heating element 221 is deflected, and a gap is generated between two adjacent fan-shaped heating elements 221. The torsion spring rod 1 adapts, and the deflected fan-shaped heating element 221 drives the dried granular material near the top surface to tilt. The granular material falls from the gap between the two adjacent fan-shaped heating elements 221 due to gravity. Since the cross bar 223 and the protrusion 224 rotate at a constant speed, each time a single fan-shaped heating element 221 is driven to tilt at the same angle and fixed time, so the granular material can be released evenly each time it tilts.

[0043] The fan-shaped heating element 221 is unloaded when it is in an inclined state. After the torsion spring rod is driven to reset, the fan-shaped heating element 221 is dried in a horizontal state. Multiple fan-shaped heating elements 221 are alternately dried and unloaded, which improves the continuity of test analysis, eliminates the pretreatment step of centralized drying before testing, simplifies the test process, and is conducive to avoiding the situation where a large amount of drying is caused during pretreatment, and the drying cannot be uniformly carried out within the prescribed drying time, resulting in agglomeration, thereby causing inaccurate test results.

[0044] Reference Figure 1 、 Figure 5 and Figure 6 The diffusion mechanism 3 is used to expand the range of downward feeding of particulate material. The diffusion mechanism 3 includes two trapezoidal inclined plates 31 symmetrically arranged on the support assembly 21. The trapezoidal inclined plates 31 are narrow at the top and wide at the bottom. The two trapezoidal inclined plates 31 are fixedly connected to a guide bar group 32 on one side close to each other.

[0045] Reference Figure 1 and Figure 7 The unloading mechanism 4 includes a support frame 41 fixedly connected to the top wall of the analyzer body 1 and a dispersion component 42 and an anti-blocking component 43 arranged on the support frame 41. The dispersion component 42 is used to further disperse the particulate material. The dispersion component 42 drives the anti-blocking component 43 through a deflection action. The dispersion component 42 cooperates with the anti-blocking component 43 to help the particulate material form a single particle flow.

[0046] Reference Figure 1 、 Figure 5 and Figure 6The trapezoidal inclined plate 31 is fixedly connected between the heating bucket 212 and the support frame 41. The trapezoidal inclined plate 31 on the left is inclined toward the lower right, and the trapezoidal inclined plate 31 on the right is inclined toward the lower left. The guide bar group 32 includes multiple guide bars, among which the guide bar in the middle is vertical and the upper end is wedge-shaped, and the other guide bars are all bent. The guide bars diffuse the granular material on the surface of the trapezoidal inclined plate 31 from the middle to the front and rear.

[0047] Reference Figures 7 to 10 The dispersing assembly 42 includes a driving member 421, and the bottom wall of the rotating seat 214 is coaxially fixedly connected with the driving member 421, and the driving member 421 is composed of a shaft connected to the rotating seat 214 and a plurality of wedge blocks 2 fixed along the circumferential direction on the bottom wall of the shaft; two plate surfaces 422 rotatably connected by a torsion spring rod are symmetrically arranged on the support frame 41, and the outer walls of the two plate surfaces 422 on the side close to each other are fixedly connected with multiple rows of blocks 423 distributed at equal intervals above and below, and the two adjacent rows of blocks 423 are staggered front and back; the upper part of the outer wall of the side close to each other of the two plate surfaces 422 are fixedly connected with a wedge block 1 424 adapted to the wedge block 2, and the side of the wedge block 1 424 away from the plate surface 422 is inclined, and the top wall of the wedge block 1 424 is fixed with a triangular block to prevent the granular material from staying.

[0048] Reference Figure 7 、 Figure 8 and Figure 10 The anti-blocking component 43 includes a fixed plate 431, the bottom walls of the two plate surfaces 422 are fixedly connected to the fixed plate 431, and the side walls of the two fixed plates 431 close to each other are connected to the L-shaped movable plate 432 for sliding back and forth through springs (not shown in the figure), and the two L-shaped movable plates 432 are symmetrical about the center; the rear part of the left L-shaped movable plate 432 and the front part of the right L-shaped movable plate 432 are fixedly connected to the protrusion three 433, and the lower side wall of the support frame 41 is fixedly connected to the protrusion four 434 corresponding to the protrusion three 433.

[0049] The fallen granular materials fall onto the upper part of the trapezoidal inclined plate 31 and slide downward under the action of gravity. The granular materials scattered on the surface of the trapezoidal inclined plate 31, which is narrow at the top and wide at the bottom, are diffused from the middle to the front and rear through the guidance of the guide bar group 32. The lower parts of the two trapezoidal inclined plates 31, which are symmetrically distributed on the left and right, form a strip space facing front and back for the granular materials to be discharged.

[0050] The two plate surfaces 422 symmetrically distributed on the left and right guide the granular materials below the trapezoidal inclined plate 31. The plate surface 422 can adaptively rotate relative to the support frame 41 through the second torsion spring rod, but the inclination angle of the plate surface 422 before and after rotation is always smaller than the inclination angle of the trapezoidal inclined plate 31, ensuring that the granular materials after passing through the trapezoidal inclined plate 31 can all fall on the surface of the plate surface 422.

[0051] After passing through the trapezoidal inclined plate 31, the granular material falls downward to the surface of the plate surface 422. After the granular material is discharged from the strip space, it is blocked by the block 423 and further dispersed. The rotating seat 214 rotates to drive the driving member 421 to rotate, and the second wedge pushes the first wedge 424. The first wedge 424 drives the upper part of the plate surface 422 to move. The second torsion spring rod rotates adaptively, and the plate surface 422 deflects the angle. The deflection angle of the plate surface 422 can change the position where the granular material falls above the plate surface 422 to prevent the two plate surfaces 422 from being blocked by granular materials near the lower position. At the same time, the second wedge pushes the first wedge 424, and the lower parts of the plate surfaces 422 move away from each other when the upper parts of the plate surfaces 422 move away from each other; when the second torsion spring rod drives the reset, the lower parts of the plate surfaces 422 move away from each other when the upper parts of the plate surfaces 422 move closer to each other.

[0052] When the plate surface 422 deflects, the fixed plate 431 and the L-shaped movable plate 432 are driven to displace synchronously. The L-shaped movable plate 432 drives the protrusion three 433 to move close to the protrusion four 434. The protrusion four 434 pushes the protrusion three 433, and the L-shaped movable plate 432 slides relative to the fixed plate 431. The spring is compressed, and the two L-shaped movable plates 432 slide in opposite directions. When the bottoms of the two plate surfaces 422 approach each other, the granular material between the gaps of the two fixed plates 431 is driven alternately back and forth by the two L-shaped movable plates 432, which helps the granular material form a single particle flow, reduces the situation of granular material stacking and unloading, and improves the accuracy of the test results.

[0053] The specific operating steps of the feeding structure of the chemical test analyzer are as follows: the granular material is placed in the heating bucket 212, and the granular material near the top surface of the fan-shaped heating element 221 is dried. The rotating seat 214 is driven to rotate by the output end of the motor, and the fan-shaped heating element 221 is driven to deflect by the cooperation of the protrusion 1 222 and the protrusion 2 224, so that the dried granular material near the top surface is tilted and evenly discharged.

[0054] The falling granular material lands on the trapezoidal inclined plate 31, spreading from the center to the front and rear. The strip-shaped space facing forward and backward provides space for the granular material to be discharged. After passing through the trapezoidal inclined plate 31, the granular material falls downward onto the surface of the plate 422, where it is blocked by the block 423 and further dispersed. The rotation of the rotating seat 214 drives the driving member 421, and the wedge block 1 424 and the wedge block 2 cooperate to deflect the plate 422. The protrusion block 3 433 and the protrusion block 434 cooperate to drive the two L-shaped movable plates 432 to move back and forth alternately, driving the granular material to form a single particle flow, reducing the occurrence of granular material stacking during discharge.
