Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to automatic grinding equipment for pharmaceutical intermediates. Background Art

[0002] Pharmaceutical intermediates are an important component of drug synthesis. During the production process of pharmaceutical intermediates, the raw materials need to be ground to control the size of the powder particles within a specific range, thereby improving the efficiency of the chemical reaction and the quality of the product. Grinding equipment is required to grind them during the grinding process.

[0003] In the prior art, after grinding pharmaceutical intermediates, the resulting materials are screened through a sieve. However, there is a risk that the intermediates are not fully ground and become stuck in the mesh of the sieve. Screen blockage reduces the screening effect of the sieve, making it inconvenient to grind the subsequent intermediates. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic grinding device for pharmaceutical intermediates, which has the advantages that: under the elastic force of the vibration spring, the screen is driven to vibrate back and forth, and the stuck material is shaken off by the vibration, so that the screen can discharge the material normally, thereby improving the grinding effect of the pharmaceutical intermediates.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: an automatic grinding device for pharmaceutical intermediates, comprising a grinding barrel with a feeding port provided on the grinding barrel, a grinding disc driven by a motor provided in the grinding barrel, a grinding groove provided on the inner wall of the grinding barrel below the grinding disc, the grinding disc and the grinding groove both having a funnel-shaped structure, a discharge pipe connected to the bottom of the grinding groove, a solenoid valve fixedly connected to the discharge pipe, and a screen connected to the grinding barrel via a vibration component;

[0006] The vibration assembly includes a vertical slot opened on the inner side of the grinding barrel, a vibration spring is arranged in the vertical slot, a connecting rod connected to the screen is arranged on the top side of the vibration spring, and a vibration motor is installed at the bottom of the screen;

[0007] A dust processing component is provided on the outside of the grinding barrel, and a discharge port is provided near the bottom of the grinding barrel.

[0008] Through the above technical solution, the pharmaceutical intermediate is poured from the feeding port and ground by the grinding disc. The ground material falls onto the screen. When the incompletely ground material is stuck on the screen, the vibration motor is driven to drive the screen to vibrate. Under the elastic force of the vibration spring, the screen is driven to vibrate back and forth. The stuck material is shaken off by the vibration, so that the screen can discharge the material normally, thereby improving the grinding effect of the pharmaceutical intermediate.

[0009] The utility model is further configured as follows: a limiting sleeve surrounding the lower half of the vibration spring is provided on the inner bottom side of the vertical groove.

[0010] The utility model is further configured as follows: a sliding groove is provided in the vertical groove along the height direction, and a sliding block is provided on the connecting rod to slide in the sliding groove.

[0011] The utility model is further configured as follows: the dust processing component includes a dust collecting box arranged outside the grinding barrel, an exhaust pipe is connected between the dust collecting box and the grinding barrel, and an exhaust pump is fixedly connected to the exhaust pipe.

[0012] The utility model is further configured as follows: a water storage tank is provided on the top side of the dust collection box, a water pumping pipe is connected between the water storage tank and the dust collection box, a water pump is fixedly connected to the water pumping pipe, one end of the water pumping pipe passing through the water storage tank is connected to a drainage pipe, the drainage pipe is connected to the top side of the dust collection box, a plurality of water mist nozzles are provided at the bottom of the drainage pipe, and a water outlet is provided at the bottom of the dust collection box.

When the unground material is stuck on the screen, the vibration motor is driven to drive the screen to vibrate. Under the elastic force of the vibration spring, the screen is driven to vibrate back and forth. The stuck material is shaken off by vibration, so that the screen can discharge the material normally, thereby improving the grinding effect of the pharmaceutical intermediate.

[0019] Specifically, the pharmaceutical intermediate is poured into the feeding port 2 and ground by the grinding disc 3. The ground material falls onto the screen 7. When the unground material is stuck on the screen 7, the vibration motor 11 is driven. The vibration motor 11 drives the screen 7 to vibrate. Under the elastic force of the vibration spring 10, the screen 7 is driven to vibrate back and forth. The stuck material is shaken off by vibration, so that the screen 7 can discharge normally, thereby improving the grinding effect of the pharmaceutical intermediate.

At this time, the water pump 21 is driven to draw the water in the water tank 19 into the drain pipe 22 through the water pipe 20. The water mist nozzle 23 sprays water on the dust to achieve the effect of dust reduction. The dust dissolves in the water and is discharged through the water outlet 18, reducing the possibility of direct dust discharge and injury by human inhalation.

[0022] Operation steps: Pour the pharmaceutical intermediate from the feeding port 2, grind it through the grinding disc 3, and the ground material falls onto the screen 7. When there is material that has not been thoroughly ground and is stuck on the screen 7, drive the vibration motor 11, the vibration motor 11 drives the screen 7 to vibrate, and under the elastic force of the vibration spring 10, drives the screen 7 to vibrate back and forth, and the stuck material is shaken down by vibration, so that the screen 7 can be discharged normally, thereby improving the grinding effect of the pharmaceutical intermediate. The limiting sleeve 9 plays a limiting role on the vibration spring 10, and the slider drives the connecting rod 1 2 slides along the chute, making the screen 7 vibrate steadily up and down. When the grinding disc 3 grinds the pharmaceutical intermediate, a large amount of dust is generated. After the grinding is completed, the vacuum pump 16 is driven to draw the dust into the dust collection box 17 through the vacuum pipe 15. At this time, the water pump 21 is driven to draw the water in the water tank 19 into the drain pipe 22 through the water pipe 20. The water mist nozzle 23 sprays water on the dust to achieve the effect of dust reduction. The dust dissolves in the water and is discharged through the water outlet 18, reducing the possibility of direct dust discharge and injury caused by inhalation by the human body.
