Technical Field

[0001] The invention relates to the field of crystal powder measurement, in particular to a device for real-time collection and particle size measurement of crystal powder. Background Art

[0002] Particle size measurement of crystalline powder is an important step, which depends on its application field, required performance and multiple aspects of the production process. Here are some of the main reasons for particle size measurement: Performance optimization: Particle size directly affects the physical and chemical properties of crystalline powder, such as specific surface area, solubility, reactivity, etc. By accurately measuring the particle size, these properties can be optimized to meet the needs of specific applications. Quality control: In the production and R&D process, the uniformity of particle size is crucial to ensure product quality. Particle size measurement helps monitor the production process, ensure the consistency between product batches, and detect possible quality problems. Application requirements: Different application fields have different requirements for the particle size of crystalline powder. For example, in pharmaceutical preparations, the particle size of crystalline powder affects the dissolution rate, bioavailability and stability of the drug; in the field of catalysts, the particle size may affect the catalytic activity and selectivity. Commonly used particle size measurement methods include laser particle size analyzer, scanning electron microscopy (SEM), transmission electron microscopy (TEM), dynamic light scattering (DLS), etc. Which method to choose depends on factors such as the nature of the sample, the required measurement accuracy, and experimental conditions.

[0003] The particle size measuring devices in the prior art are generally manually operated for collection and measurement during use, resulting in low efficiency in the collection and measurement of crystal powders, and the inability to continuously and automatically perform real-time collection and particle size measurement of crystal powders. Therefore, we propose a real-time collection and particle size measurement device for crystal powders. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art, adapt to actual needs, and provide a real-time collection and particle size measurement device for crystal powder to solve the problem that the particle size measurement device in the current prior art is generally manually operated to collect and measure when in use, resulting in low efficiency in the collection and measurement of crystal powder, and the technical problem that the real-time collection and particle size measurement of crystal powder cannot be continuously and automatically performed.

[0005] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is: designing a crystal powder real-time collection and particle size measurement device, including a conveyor belt, a concave plate body passing through the inside of the conveyor belt, a collection shell attached to the top of the conveyor belt, an inclined groove integrally formed at the front end of the collection shell, a plurality of collection holes are opened on the surface of the inclined groove, both sides of the top of the collection shell are connected to an air suction pump, the top of the air suction pump is connected to a first connecting pipe, the top of the first connecting pipe extends into the collection shell, and is connected to a storage tank in the collection shell, and an injection mechanism is arranged inside the storage tank;

[0006] A measuring box is installed on the top of the collection shell, and a measuring component is arranged inside the measuring box.

[0007] Preferably, the jet mechanism comprises a jet pump installed at the top of the storage tank, a second connecting pipe connected to the bottom of the jet pump, and an L-shaped jet pipe connected to the top of the jet pump.

[0008] Preferably, the top of the L-shaped jet pipe passes through the storage tank and the collection shell and extends into the measuring box to spray the crystal powder into the measuring box.

[0009] Preferably, the measuring assembly comprises a motor installed on the top of the measuring box, a rotating disk connected to the motor, and a microscope installed at the rear end of the measuring box.

[0010] Preferably, the bottom of the motor extends into the measuring box and is connected to a rotating disk at the bottom of the measuring box, and a plurality of glass slides are placed around the surface of the rotating disk.

[0011] Preferably, one end of a hinge is rotatably connected to one side of the front end of the measuring box, and a box baffle is fixed to the other end of the hinge.

[0012] Preferably, square holes are opened on both sides of the front end of the collection box body, the storage tank passes through the square hole, and a front cover plate is installed at the front end of the storage tank.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention combines a collecting shell, a conveyor belt and an air suction pump, so that not only can the conveyor belt be used to continuously convey the crystal powder, but also, in the process of conveying the crystal powder, the air suction pump on the top of the collecting shell can be used to draw the crystal powder into a storage tank for storage, and the jet pump in the storage tank can be used to draw the crystal powder in the storage tank and spray it on multiple glass slides on the surface of the rotating disk. Since multiple jet pumps and air blowing pipes are provided, the crystal powder can be sprayed on multiple glass slides at the same time, which improves the spraying efficiency. The rotating disk drives the multiple glass slides to rotate, and the particle size of the crystal powder on the surface of the multiple glass slides can be measured separately through a microscope, which further improves the measurement efficiency and solves the problem that the particle size measuring device in the prior art is generally manually operated for collection and measurement during use, resulting in low collection and measurement efficiency for the crystal powder, and the technical problem that the crystal powder cannot be continuously and automatically collected in real time and the particle size measurement cannot be performed.

[0015] 2. The present invention combines a collection shell, an inclined slot and a collection hole, so that the crystal powder can be accumulated on the surface of the inclined slot during the process of conveying the crystal powder by the conveyor belt. The collection holes on the surface of the inclined slot are connected to an air suction pump to absorb the crystal powder at different positions on the surface of the conveyor belt, thereby solving the technical problem that the collection device in the prior art is prone to leaking a part of the crystal powder when directly extracting through a pipeline.

[0016] The present invention integrates a crystal powder collection device and a particle size measurement device, and does not require manual collection and particle size measurement, thereby improving the efficiency of crystal powder collection and particle size measurement.
