Description

Technical Field

[0001] The invention belongs to the technical field of chemical medicine crushing, and specifically refers to a crusher for chemical industry. Background Art

[0002] The production process of chemical drugs consists of two parts: API production and drug preparation production. APIs are the material basis of drug production, but they must be processed into drug preparations suitable for oral administration before they become drugs. APIs are generally solid substances. Compared with liquids and gases, solids have a relatively fixed volume and shape and a relatively hard texture. In the pharmaceutical production process, solid APIs need to be crushed and ground. Existing grinding equipment will generate a lot of heat during grinding, which will affect chemical drugs. High-temperature chemical powders will condense water vapor during the cooling process, causing the chemical powders to become moist. The ground chemical powders need to be dried again, which increases the workload and reduces the efficiency of chemical processing.

[0003] Therefore, a chemical crusher is needed to solve the above problems. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a chemical crusher, which uses the pressure in the cooling and drying chamber to quickly decrease to lower the temperature, and then transports the low-temperature gas into the outer cylinder, which can both cool the chemical powder and dry the chemical powder.

[0008] Furthermore, the electromagnetic lifting assembly includes a lifting cylinder, an upper fixed platform, a lower fixed platform, a fixed rod and a driving spring, the upper fixed platform is arranged on the outer wall of the linkage rod, the lower fixed platform is arranged on the lower part of the outer wall of the outer cylinder, the lower end of the fixed rod is arranged on the upper wall of the lower fixed platform, the upper end of the lifting cylinder is arranged on the lower wall of the upper fixed platform, the fixed rod is slidably arranged in the lifting cylinder, the driving spring is sleeved on the fixed rod, the upper end of the driving spring is fixedly arranged on the lower end of the lifting cylinder, the lower end of the driving spring is fixedly arranged on the upper wall of the lower fixed platform, and the driving spring is connected to an external power supply.

[0009] Furthermore, the cone angle of the grinding chamber is greater than the cone angle of the rotating grinding body, and the gap between the grinding chamber and the rotating grinding body gradually decreases from the top of the cone to the bottom of the cone.

[0010] Furthermore, a baffle is provided at the vent hole near the cooling and drying chamber, a center hole is penetrated through the baffle, an elastic rubber membrane is provided at the vent hole away from the cooling and drying chamber, small holes are provided on the elastic rubber membrane, and the elastic rubber membrane is tightly attached to the baffle.

[0014] Furthermore, a pocket fixing ring is provided on the lower end surface of the outer cylinder.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: 1. When the electromagnetic lifting assembly drives the linkage rod to rise and fall, the linkage rod drives the sealing piston to rise and fall. When the sealing piston rises rapidly, the pressure in the cooling and drying chamber decreases rapidly, and the temperature decreases. When the sealing piston descends, low-temperature gas enters the outer cylinder from the central hole of the baffle and the small hole of the elastic rubber membrane, which can not only cool down the chemical powder, but also dry the chemical powder; 2. A baffle and an elastic rubber membrane are provided in the vent hole. When the air pressure in the cooling and drying chamber decreases, the elastic rubber membrane will not be deformed because the baffle blocks the elastic rubber membrane. Since the elastic rubber membrane is elastic and can squeeze the small hole, it has a sealing effect. The gas in the outer cylinder will not be sucked into the cooling and drying chamber, ensuring that the air pressure in the cooling and drying chamber is rapidly reduced.

[0025] like Figure 4 As shown, the cone angle of the grinding chamber 18 is greater than the cone angle of the rotating grinding body 12, and the gap between the grinding chamber 18 and the rotating grinding body 12 gradually decreases from the top of the cone to the bottom of the cone.

[0026] like Figure 7 , Figure 8 , Fig.11 As shown, the vent 10 is provided with a baffle 25 near the cooling and drying chamber 3, and a center hole 26 is penetrated through the baffle 25. The vent 10 is provided with an elastic rubber membrane 27 away from the cooling and drying chamber 3, and a small hole 31 is provided on the elastic rubber membrane 27. The elastic rubber membrane 27 is tightly attached to the baffle 25. Since the elastic rubber membrane 27 is elastic and can squeeze the small hole 31, it has a sealing effect when the elastic rubber membrane 27 is not deformed.

[0027] like Figure 3 , Figure 5 , Figure 6 As shown, the inner end surface of the clamping block 14 is an arc surface, and the end surface of the clamping block 14 matches with the inner wall of the clamping slot 19 .

[0028] like Figure 1 As shown, a funnel 28 is provided on the upper wall of the support plate 9 , and the funnel 28 is connected to the feed pipe 13 .

[0029] like Figure 1 As shown, a one-way valve 29 is disposed on the outer wall of the outer cylinder 1 , and when the sealing piston 7 moves upward, gas can slowly enter the cooling and drying chamber 3 from the outside.

[0030] like Figure 1 , Figure 7 As shown, a pocket fixing ring 30 is provided on the lower end surface of the outer cylinder 1.

[0031] When in use, firstly, the pocket is sleeved and fixed at the pocket fixing ring 30, and the block chemicals are added into the funnel 28, and the chemicals enter the grinding chamber 18 along the feeding pipe 13, and the power connected to the driving spring 24 is turned on. The driving spring 24 contracts after being energized, and the driving spring 24 drives the lifting cylinder 20 to descend along the fixing rod 23, and the lifting cylinder 20 drives the upper fixing platform 21 to descend, and the upper fixing platform 21 drives the linkage rod 8 to descend, and the linkage rod 8 drives the sealing piston 7 to descend, and the sealing piston 7 pushes the air in the cooling and drying chamber 3 to squeeze the elastic rubber film 27 from the central hole 26 of the baffle 25, and the elastic rubber film 27 is deformed, and the small hole 31 on the elastic rubber film 27 increases in size, and the air enters the interior of the outer cylinder 1 from the small hole 31 of the elastic rubber film 27; At the same time, the linkage rod 8 drives the support plate 9 to descend, the support plate 9 drives the discharge pipe 13 to descend, and the discharge pipe 13 drives the fixed grinding body 11 and the rotating grinding body 12 to descend. In the initial state, the driving magnetic block 15 on the rotating grinding body 12 is aligned with the second fixed magnetic block 17 along the axial direction. When the driving magnetic block 15 on the rotating grinding body 12 descends to be flush with the first fixed magnetic block 16, due to the magnetic attraction between the first fixed magnetic block 16 and the driving magnetic block 15, the driving magnetic block 15 and the first fixed magnetic block 16 tend to overlap, so that the driving magnetic block 15 drives the rotating grinding body 12 to rotate, and the rotating grinding body 12 and the fixed grinding body 11 move relative to each other, so as to grind the chemicals in the grinding chamber 18. When the fixed grinding body 11 and the rotating grinding body 12 continue to When the drive magnetic block 15 continues to descend, it descends until it is flush with the second fixed magnetic block 17. At this time, the second fixed magnetic block 17 and the drive magnetic block 15 are magnetically attracted to each other, and the drive magnetic block 15 and the second fixed magnetic block 17 tend to overlap, so that the drive magnetic block 15 drives the rotating grinding body 12 to rotate in the opposite direction, and the rotating grinding body 12 and the fixed grinding body 11 move relative to each other, and the chemicals in the grinding chamber 18 are ground again. In the process of the fixed grinding body 11 and the rotating grinding body 12 continuing to descend, the drive magnetic block 15 is alternately subjected to the magnetic attraction force of the first fixed magnetic block 16 and the second fixed magnetic block 17, so that the rotating grinding body 12 can reciprocate forward and reverse, and the chemicals are ground into powder. The ground chemical powder falls into the outer cylinder 1 and then enters the pocket. When the driving magnet 15 descends to the vent hole 10, the driving spring 24 is de-energized, and the driving spring 24 bounces the lifting cylinder 20 upward, and the lifting cylinder 20 drives the upper fixed platform 21 and the linkage rod 8 to move upward, and the linkage rod 8 drives the sealing piston 7 to move upward rapidly. Since the baffle 25 blocks the elastic rubber film 27, the gas in the outer cylinder 1 will not be sucked into the cooling and drying chamber 3, and the pressure in the cooling and drying chamber 3 decreases rapidly, and the temperature decreases. According to the above operation, when the sealing piston 7 descends, the cold air entering the inner part of the outer cylinder 1 from the central hole 26 of the baffle 25 and the small hole 31 of the elastic rubber film 27 is low-temperature gas, which can both cool the chemical powder and dry the chemical powder.
